What is Alpha School in America, where AI teaches instead of teachers!

 What is Alpha School in America, where AI teaches instead of teachers!


What comes to mind when you think of ‘school’? Surely, for many, classrooms from kindergarten to 12th grade, front-line teachers, and long lessons come to mind. This is how schools have been set up for centuries. But now, as AI is changing our lifestyle, the traditional way of learning and schooling has also started to take a new form.



Alpha School, located in Texas, USA, has become a global sensation due to its unique and modern way of teaching students. Instead of a teacher teaching 25-40 students at a time as per the traditional style, it is said that in this school, students are instructed individually by AI guides. It is said that the AI ​​system also analyzes their progress and provides immediate feedback, which helps them improve their weaknesses.


At Alpha School, students are said to have to study for only 2 hours a day. According to international media, after two hours of study, Alpha School students spend time on physical activity, problem-solving activities, leadership exercises, and life skills. These include activities ranging from long bike rides to creative projects and entrepreneurship training.


Another feature of Alpha School is its financial rewards system. Students are said to earn money for completing assignments, projects, or mastering skills, which they can spend on their own projects or interests, or even invest.


According to international media, Alpha School is not a school that appeared overnight or became famous. It has been operating on campuses in Texas, Florida, and California for more than a decade, and is now preparing to expand to New York City. It is said that a new Alpha campus is planned to open in Manhattan next September, with annual tuition fees ranging from $40,000 to $65,000, depending on the location.


This unique and technological teaching style demonstrated by Alpha School has shown the potential for education to take on a completely new form through innovation, not just limited to books and teachers.


What are the procedures for postmortems and identification of those who died in the protests?

 What are the procedures for postmortems and identification of those who died in the protests?


Coordination between forensic science, police, and hospitals is necessary to identify and determine the cause of death of those who died during the protests.

An official letter of medico-legal examination from the police is required before the postmortem is conducted, which confirms the cause of death.

DNA analysis and other scientific methods are used to identify bodies that have been burned, but identifying completely burned bodies is challenging.

Violent incidents during protests cause great human loss. In such incidents, a complex and sensitive procedure is adopted to identify and determine the cause of death of those who die due to gunshots, fire, or other injuries.



Coordination between forensic science, as well as the police, and hospitals is very important to identify and determine the cause of death of the deceased. This process is sensitive from both a scientific and legal perspective.


Incident and initial procedures


People who die during the protests are often taken to the hospital immediately by eyewitnesses or friends. The name of the deceased is registered in the hospital and treatment is attempted. If the person is confirmed not to be alive, the body is sent for postmortem. Tribhuvan University Teaching Hospital, Kathmandu is a well-equipped centre for mortuary storage and postmortem. The body is preserved in a freezer facility. The teaching hospital has the necessary equipment for proper management of the body and postmortem, which makes the process systematic.


Identification process of the deceased


Initial identification


The identity cards, jewellery or other personal belongings of the deceased form the initial basis for identification. The name and address of the deceased can be ascertained from such items. If such items are not available, the relatives come to the hospital and identify the body.


Personal belongings are of great help in the identification process, but sometimes other scientific methods have to be used in cases where these items are destroyed.


Notification to relatives


Once the details of the deceased are registered in the hospital, the relatives are informed. The hospital maintains a list of the names of the deceased, which the relatives look at to identify the body. Once the identity is confirmed, the postmortem process proceeds.


Postmortem and medico-legal process


A medical-legal examination is required from the police before a postmortem can be conducted. In cases where police stations are affected, such a letter is issued by the Kathmandu Police Complex. A postmortem determines the cause of death, such as gunshot wounds, injuries or fire. This process is important for the relatives of the deceased and the community to uncover the truth.


The main causes of death during the protests currently include gunshot wounds, internal injuries, head injuries or fire. In cases of gunshot deaths, doctors analyze the nature of the bullet and the damage to the body.


Identification of people who died in a fire


The identification of bodies that died in a fire is complicated. For example, in the case of seven people who died in a fire in Bhatbhateni, identification is challenging. Methods such as presumptive identification and DNA analysis are used to identify burned bodies. If jewelry, clothes or other personal belongings are left, they can be used to identify them.


DNA Analysis


When a body is not completely burned and some tissue remains, DNA is extracted and analyzed. This process is carried out at the Central Forensic Science Laboratory of the Nepal Police. DNA analysis can confirm the identity of the deceased, but this process is time-consuming and resource-intensive.


DNA Analysis Process


DNA Extraction


DNA is extracted from white blood cells, because red blood cells do not have a nucleus. DNA can be extracted from bones or teeth in burned bodies, if they are not destroyed.


Polymerase Chain Reaction (PCR-M)


If the amount of DNA is low, the amount of DNA is increased by the PCR-M process. This makes it easier to analyze the DNA sequence adenine, guanine, thymine, cytosine.


Profile Matching


The DNA profile of the deceased is compared with the DNA of his father or mother. A 50 percent match between the father or mother's DNA confirms the identity.


Challenges in completely burnt bodies


If the body is completely burnt and the tissues are destroyed, DNA analysis is not possible. In such a case, identification becomes impossible. Also, if the relatives of the deceased do not contact them in time, the process becomes more complicated. The possibility of identifying completely burnt bodies is limited, but we must make the most of the resources and technology available.


This process is not only to identify the deceased and determine the cause of death, but it is also a means of ensuring truth and justice in society. Such sensitive processes provide comfort to the victim’s family and provide truthful information to society.

Back Pain: An Accounts Officer in the Circle of Wrong Treatment

 Back Pain: An Accounts Officer in the Circle of Wrong Treatment


Accounts Officer Tilak Shrestha started treatment for back pain at the Physiotherapy Unit of Bir Hospital in 2082 Jestha.

Tilak spent more than two hundred thousand rupees on various clinics and treatments for 6 months, but it did not get better.

Physiotherapy at Bir Hospital reduced Tilak's pain by teaching him evidence-based treatment and exercises, and he returned to work.

Tilak Shrestha (name changed) by profession, an accounts officer by profession, arrived at the Physiotherapy Unit of Bir Hospital in 2082 Jestha.



His problem was back pain.


He came here after wandering around many places for treatment but the problem was not resolved.


He recounted the list of frustrations he faced during treatment.


This experience is not unique to him, many people with back pain experience the same. Many people fall into the trap of wrong treatment by following unnecessary suggestions from various people.


Suffering from pain


Tilak had been suffering from back pain for 6 months. The pain was worse when he woke up in the morning. It was worse when he sat or stood for a long time. At first, he ignored it, considering it normal. The pain gradually spread to his legs and made it difficult to walk. He even changed his office chair twice, wondering if it was because he was uncomfortable sitting while working.


Unable to concentrate on work, unable to sit in the office for a long time, and daily life became difficult, he started looking for treatment.


Initial efforts


Initially, he went to an Ayurvedic treatment center in Basundhara as suggested by his uncle. There, he was told that his back hurt due to heavy lifting and sitting in the wrong posture. Tilak did not do heavy lifting. He concluded that his back hurt because he sat in the same position for a long time in the office.


He was given acupuncture services, hot water baths, and massage once a week. He was also told to take some medicines. Although these treatments reduced some of the pain, the problem did not completely resolve. He was charged Rs. 2200 each time for these treatments. The cost of the medicine was separate.


After the fourth massage during the treatment, he started having problems with tingling in his legs and increasing pain.


And at the clinic


When the problem did not work, he went to a clinic near his house to consult a doctor. On the doctor's advice, he got blood tests and X-rays done. These tests did not show any major problems. He was informed that there was a normal bone loss.


It was suggested that further tests be done for further investigation. Accordingly, tests were done for CBC, ESR, vitamin D, calcium, uric acid levels, etc. Additional blood tests were also done for other parameters.


After finding that all the parameters were normal, an MRI was asked to find out the cause of the back pain.


In the same clinic, ‘needle therapy’, ‘traction’, ‘tension’ were given as physiotherapy. However, Tilak did not feel any improvement. Instead, he felt more pain. He was advised to rest for some time and stay at home, not go to the office and not do daily household chores.


Second clinic and expensive expenses


Then he was advised to go to a clinic in Tripureshwor. After examining his problem, it was suggested that he should burst the lump in the back. For this, methods such as ‘needling’, ‘manual’, ‘chiropractic’ massage gun were used.


He underwent the treatment as prescribed there for 15 days at a rate of 1000 per day. But the pain did not reduce much.


More expenses at the third clinic


Then he went to another clinic near the Civil Hospital in Baneshwor. There he spent 500 per day and took hot steam for 9-10 days. He also took massage therapy for the same number of days. He spent 600 per day on that. Here, he spent about 10 thousand.


Although these simple massages and steam treatments provided immediate relief from the pain, they did not provide a long-term solution.


Towards natural treatment


Finally, Tilak went to a center in Baneshwor to seek natural treatment. Where he underwent treatment for 10 days continuously. There, treatments like ‘acupuncture’, ‘cupping’ were given. There, he was given 10 minutes of physiotherapy daily. In which the therapist would stretch his hands and teach him some exercises to do on his own.


These treatments also could not completely cure Tilak’s back pain.


Consultation with a doctor at the National Trauma Center


After many types of treatment did not help, he went to the National Trauma Center to consult an orthopedic doctor. There, the doctor said that the condition was very complicated and that an MRI should be done.


The doctor suggested taking medicine and doing physiotherapy for some time. If that did not help, he was told to get injections.


Tilak informed the doctor that he had not gotten better despite undergoing physiotherapy at various places. After hearing all that, the doctor suggested injections and surgery if necessary, and ordered an MRI.


At the Pain Care Center


Tilak was scared when they said injections and surgery would be necessary. When he consulted his friends and relatives, some gave examples of people who had undergone surgery and recovered, while others advised against surgery. This confusion left him in a dilemma.


After being diagnosed, he again started looking for non-surgical treatment. In the same vein, he reached the Pain Care Center. There, he was prescribed medicine for 20 days. After undergoing various therapies and treatments, he took the service for a few days at the rate of 700 rupees per day.


6 months of suffering and unnecessary expenses


Tilak went to various places for about 6 months for treatment of his back pain. During this, he had to endure physical pain, mental stress, work interruptions, and expenses of more than two hundred thousand rupees. He could not give time to his family. And his lifestyle was greatly affected.


He took 18 days off from work repeatedly during this time. Even after all this treatment, problems such as difficulty doing household chores, sitting in the office for long periods of time, and pain increasing when riding a scooter in potholes persisted.


What is his real problem?


The problem of back pain and the experience of suffering for treatment are common problems for many back pain patients in Nepal. In most cases, back pain is common and complications are rare. But if there is a health problem, it seems that the problem becomes more complicated when various people give various suggestions and the patient follows them.


The use of non-physiotherapy in the name of physiotherapy or the failure to use evidence-based physiotherapy treatment methods are also causing unnecessary suffering to the patient.


Time and money are being spent for free on treatments that do not yield results. There is a tendency to confuse patients by promoting new and unproven methods.


A misconception and practice that when there is a pain problem, an ‘MRI should be done’ at the first appointment has increased in Nepal. On the one hand, there is the problem of healthcare workers who insist on getting an MRI, and in some cases, patients themselves are dissatisfied with the healthcare workers not suggesting an MRI. There are also patients who think that the doctor did not ask for an MRI, perhaps ignoring my problem.


In fact, most back pain is not unnecessary to get an MRI. When an MRI is performed for normal pain, it may show normal ‘disk bulging’ or ‘degenerative changes’, which are also seen in many healthy people with age. When patients are told about these things seen on an MRI, patients are unnecessarily scared. They consider it a big problem and worry.


Similarly, the practice of injecting ‘steroids’ to relieve pain is also increasing in Nepal. Although steroids relieve pain immediately, their long-term effects and repeated use can have negative effects on the body.


What is even more worrying is the increasing trend of recommending surgery for simple back pain. While only 1-2 percent of back pain sufferers have a complex problem that requires surgery.


This is why patients are going through unnecessary suffering, expense, and mental stress. We need to understand that back pain is not a serious illness, it is a normal reaction of the body and can be managed with proper understanding.


The most important thing for back pain is reassurance, patience, and accurate information. About 95 percent of back pain is of a normal nature. It resolves on its own within 6 weeks to 3 months or is completely cured with good self-management.


Evidence-based ‘conservative’ treatment should be the first priority for the first 3 to 6 months. It is necessary to receive individualized physiotherapy services from a certified physiotherapist.


Exercises and hands-on therapies such as mobilization, manipulation, and stretching are provided according to the person’s condition, pain level, and functional capacity. The main goal of physiotherapy is to prepare the patient for self-management by teaching them about their body and pain. The physiotherapist assesses the patient’s functional capacity and suggests ways to increase their functional capacity.


This includes the following:


1. Self-management and patient education


The patient should be explained why back pain occurs, what its normal course is, and that in most cases it can resolve on its own. It is important to develop the idea that ‘back pain is not always serious’. Giving the patient accurate information about their pain reduces unnecessary fear and anxiety.


Fear and anxiety can cause and worsen pain. The patient should be reassured that back pain is normal and is not a long-term problem. Instead of bed rest, they should be encouraged to be active in their usual activities.


2. Pain management and exercise


Exercises that strengthen the back and abdominal muscles, increase flexibility, and improve posture (such as cobra pose, cat-camel stretch, pull exercises) should be taught according to the patient's condition.


Activities such as walking, cycling, and swimming increase blood circulation and help reduce pain. Hot or cold packs can be used to relieve short-term pain.


If the pain is unbearable, painkillers or muscle relaxants can be used on the advice of a doctor. However, relying on such medications for long-term pain relief can have negative effects.


3. Physical exertion and continuation of daily activities


You should be encouraged to continue your normal daily activities despite the pain. Prolonged inactivity can worsen the pain. Teach the correct way to sit, stand, and walk. Correct technique should be adopted when working on a computer or lifting heavy objects. Do not stay in any one posture or position for more than 30 minutes. Take ‘microbreaks’ every 20-30 minutes, such as getting up, walking, or stretching.


4. Psychological support


This is a treatment method provided by a physiotherapist in general and a clinical psychologist in complex cases when the patient shows yellow signs. For example: The role of mental health is important in chronic pain. It helps to change negative thoughts and behaviors towards pain. Meditation and mindfulness practices teach you to reduce the feeling of pain and accept it.


In what cases is complex treatment necessary?


If back pain lasts for 6 months If the pain persists for more than a month, does not improve with treatment, or if other serious symptoms occur along with the pain, other types of treatment are necessary.


For example, if there are problems such as weakness in the legs, problems with urine or stool control, persistent fever, or pain at night, additional tests such as MRI are necessary.


In this case, steroid injections or surgery should be considered. These treatment methods should be recommended only after a thorough evaluation by a specialist doctor.


The change in Tilak


What Tilak suffered in the name of treatment, he became a victim of malpractice. Which tortures the patient financially, physically, and mentally and reduces the importance of physiotherapy.


As advised by the physiotherapy unit of Bir Hospital, Tilak started taking regular physiotherapy sessions. He was given correct information about back pain. He was taught exercises to do daily. He improved his sitting style. He started walking regularly.


He realized that back pain is not always serious and staying active is the best treatment for it. Within a few weeks, his pain significantly decreased and he was able to return to his work fully. He was spared unnecessary expense and suffering.

What are the health risks of repeatedly frying samosas and jerry in oil?

 What are the health risks of repeatedly frying samosas and jerry in oil?


Experts say, ‘Reusing oil increases the risk of heart attack, cancer and other diseases.’

Repeated heating of oil has a negative impact on health as it causes chemical changes and increases the amount of trans-fat.

It is recommended to store oil properly and use new oil.

Often, samosas, pakodas, jerry, etc. are cooked in the same oil repeatedly in chowks and markets. Some people even use the remaining oil after cooking food once in their own homes and kitchens. What happens when oil is used repeatedly in this way?



Experts say, ‘Reusing oil increases the risk of heart attack, cancer and other diseases.’


Not only at home but also in restaurants and roadside stalls, food is prepared by reheating oil. This has a negative impact on health. This can be responsible for many diseases, says senior nutritionist Bhupal Baniya.


Health effects of reusing oil


1. Chemical changes and increase in trans-fat


Repeated heating of cooking oil changes its chemical and nutritional properties. According to a study published in the Journal of Food Science and Technology (2021), repeated heating of oil increases the amount of ‘total polar compounds’, which is harmful to health.


These compounds damage the structure of the oil and increase the level of trans-fat. Bania says that trans-fat increases the risk of heart disease by increasing the amount of bad cholesterol.


According to a study published in the Journal of Nutrition 2020, reheated oil produces free radicals, which damage cells. Free radicals cause oxidative stress, which increases the risk of chronic diseases such as cancer and diabetes.


2. Cancer risk


Harvard T.H. A study by the Chan School of Public Health (2022) noted that reheated oil produces toxic substances such as aldehydes.

These substances can damage DNA, which encourages the growth of cancer cells. In particular, the oil used in fried foods is repeatedly heated, which increases the amount of these toxins, Bania said.


According to a study published in the International Journal of Cancer (2019), polycyclic aromatic hydrocarbons found in reheated oil increase the risk of cancer in the lungs, skin and other organs. This risk is especially high in fried foods in hotels and restaurants, where the oil is heated for a long time.


3. Inflammation


Reheated oil promotes inflammation. According to a study published in the American Journal of Clinical Nutrition (2021), the production of free radicals and other harmful compounds in reheated oil damages blood cells. Chronic inflammation can lead to diseases like heart disease, joint pain, atherosclerosis, and periodontitis.


4. Bacterial infections


When food particles remain in the oil, they encourage the growth of bacteria, says nutritionist Ayush Adhikari. He says, “If used oil is not stored properly, it can lead to the growth of bacteria like Clostridium botulinum, which causes botulism. This is a serious food poisoning that can cause muscle weakness, difficulty breathing, and other complications.”


5. Increase in cholesterol and acidity


According to a study published in the European Journal of Lipid Science and Technology (2023), the amount of saturated fat and oxidized lipids in repeatedly heated oil increases.


These compounds increase cholesterol levels, which harm the heart and blood vessels. In addition, the use of such oil can cause acidity, gas and digestive problems in the stomach, said Adhikari.


Ways to avoid reusing oil


Adhikari says that reusing oil can be avoided by cooking less. He says, "Do not use more oil than necessary and cook in small quantities. This reduces the chances of oil remaining."


You should try to use fresh oil every time you cook. If oil remains, he suggests storing it properly. After the used oil cools down, it should be carefully filtered to remove food particles. This prevents the growth of bacteria, said Adhikari.


"If oil is left over while cooking, it should be stored properly," says Adhikari. "The oil should be stored in a cool and dry place, away from sunlight and heat. Keeping it in the refrigerator reduces the growth of bacteria."


To avoid health problems caused by reusing oil, nutritionist Baniya suggests staying away from fast food and packet food. “These foods should be consumed less frequently as heated oil is frequently used in roadside stalls and restaurants,” says Bania.


He also says that it is important to avoid heating oil for a long time while cooking.


“When cooking, use mustard oil, olive oil or other oils with low saturated fat,” suggests Bania. “These oils are less harmful to heart health.”


Different oils have different smoke points. For example, olive oil is suitable for use at low heat, while sunflower or canola oil can be used at high heat. He also suggests paying attention to these things.


According to Bania, if there is a change in the color, smell or texture of the oil, it should be discarded. No. Such oil may contain high levels of harmful compounds, so the quality of the oil should be checked before use.

What happens in the body when we are in deep sleep?

 What happens in the body when we are in deep sleep?


Sleep is as necessary as nutritious food and pure water. Why do people feel sleepy? Why is it necessary to sleep? To know these mysteries, another important question is necessary, ‘What happens in our body when we are in deep sleep?’



Why do we feel sleepy?


Sleep also has stages. It is mainly divided into two parts. The first is rapid eye movement. The second is non-rapid eye movement. Apart from this, there are three more stages, which are called N-1, N-2 and N-3.


Out of these, N-3 is the deep sleep stage. It is also called wave sleep. We usually enter this stage within the first two hours of sleep. That is, we reach deep sleep. This is repeated in short periods throughout the night.


During this stage, i.e. deep sleep, the brain produces delta waves. This wave slows down brain activity and puts the body into a deep state of rest. It is very difficult to wake people up in this state. Even if they wake up, they often feel confused or unfocused.


Processes that occur in the body during deep sleep


During deep sleep, the body carries out various physical processes that play an important role in maintaining health and functionality.


1. Cell repair and growth


During deep sleep, the body repairs and regenerates cells. During this period, the production of growth hormone is high. Especially in children and adolescents. This hormone helps in the growth and repair of muscles, bones and other cells. In adults, this hormone also plays an important role in healing injuries, strengthening muscles and repairing cells.


During this time, the body also accelerates protein synthesis, which helps in regenerating damaged cells and building new cells.


2. Increases immunity


During deep sleep, the immune system is strengthened. During this time, the body produces proteins like cytokines, which are necessary to fight infection. Lack of sleep weakens the immune system.


Sleep promotes the activity of T-cells and other immune cells. These cells destroy viruses and bacteria that enter the body. Vaccines are also more effective in people who get enough sleep.


3. Brain cleansing and memory


During deep sleep, the brain cleanses itself and strengthens memory. In this process, it removes toxins and waste from the brain. Deep sleep also helps in increasing memory. The things learned throughout the day are organized in the brain and converted into long-term memory. This process is driven by the interaction between the hippocampus and the neocortex.


4. Energy storage and digestion


During deep sleep, the body's digestive rate decreases, which conserves energy. Heart rate, breathing, and body temperature decrease, which allows the body to rest. During this period, the body controls glucose utilization and improves insulin sensitivity, which reduces the risk of diabetes.


Sleep also controls levels of stress hormones such as cortisol. If sleep is lacking, cortisol levels increase, which increases the risk of stress, anxiety, and obesity.


5. Heart Health


Sleep helps keep the heart and circulatory system healthy. Blood pressure and heart rate decrease during this time, which relaxes the heart. People who get regular sleep have a lower risk of high blood pressure, heart attack, and stroke. In addition, during this time, the body also focuses on repairing blood vessels and reducing inflammation.


Effects of sleep deprivation


If sleep deprivation occurs, various body systems are negatively affected. Sleep deprivation weakens memory, reduces immunity, increases stress, and imbalances in digestion. In the long term, sleep deprivation increases the risk of diseases such as diabetes, obesity, heart disease, depression, and Alzheimer's.


How to get a good night's sleep?


Regular sleep schedule: Go to bed and wake up at the same time every day.


Sleeping environment: A quiet, dark, and comfortable room.


Limit screen time: Reduce mobile and computer use before bed.


Healthy lifestyle: Regular exercise, a balanced diet, and stress management.

What are the top 3 types of insurance? What is risk in insurance?

 What are the top 3 types of insurance? What is risk in insurance?


The **top three types of insurance** are typically the ones most essential for individuals and families to ensure financial security and peace of mind. Here's a breakdown of each:  



---


### 1. **Health Insurance**  

**Why It’s Important:**  

Health insurance covers medical expenses, including doctor visits, hospital stays, surgeries, and medications. It ensures that individuals and families can access necessary healthcare without facing overwhelming financial burdens.  


**Key Benefits:**  

- Covers preventive care (e.g., vaccinations and check-ups).  

- Reduces out-of-pocket costs for major medical procedures.  

- Protects against unexpected health crises and chronic conditions.  


**Popular Options:**  

- Employer-sponsored health plans.  

- Government programs like Medicare and Medicaid.  

- Private health insurance policies.  


---


### 2. **Life Insurance**  

**Why It’s Important:**  

Life insurance provides financial support to your loved ones in the event of your death. It helps cover expenses like funeral costs, outstanding debts, and future living expenses for your family.  


**Key Benefits:**  

- Ensures financial stability for dependents.  

- Helps pay off mortgages, loans, and other debts.  

- Offers peace of mind, knowing your family is financially secure.  


**Types of Life Insurance:**  

- **Term Life Insurance:** Coverage for a specific period (e.g., 10, 20, or 30 years).  

- **Whole Life Insurance:** Lifetime coverage with a cash value component.  

- **Universal Life Insurance:** Flexible policies with investment options.  


---


### 3. **Auto Insurance**  

**Why It’s Important:**  

Auto insurance is often required by law and protects drivers from financial liabilities related to car accidents, theft, or damage. It covers both personal and third-party risks.  


**Key Benefits:**  

- Covers repair or replacement costs for your vehicle.  

- Provides liability coverage for damages or injuries caused to others.  

- Protects against uninsured or underinsured drivers.  


**Coverage Options:**  

- **Liability Insurance:** Covers damages and injuries you cause to others.  

- **Collision Coverage:** Pays for damage to your own vehicle.  

- **Comprehensive Coverage:** Covers non-collision-related damages, like theft or natural disasters.  


---


### Why These Three?  

These types of insurance address the most common and critical risks individuals face: health emergencies, the financial impact of death, and liabilities related to vehicle use. Together, they form the foundation of a sound financial protection plan.  



In the context of insurance, **risk** refers to the possibility or likelihood of an event occurring that could result in financial loss, injury, or damage to property. Insurance is fundamentally about managing this uncertainty by transferring the financial burden of potential risks from the insured to the insurer.


---


### **Types of Risk in Insurance**

1. **Pure Risk**  

   - Involves situations where there is only a possibility of loss or no loss, with no potential for gain.  

   - Examples: Natural disasters, theft, illness, or death.  

   - Insurers typically cover pure risks because they can be measured and predicted statistically.  


2. **Speculative Risk**  

   - Involves situations where there is a possibility of loss, no loss, or a gain.  

   - Examples: Investments, business ventures.  

   - Speculative risks are not insurable because they depend on individual choices and market conditions.  


---


### **Components of Risk in Insurance**

1. **Peril**  

   - A specific cause of loss, such as fire, flood, or accident.  

   - Example: A house burning down due to a fire is a peril.  


2. **Hazard**  

   - Conditions or circumstances that increase the likelihood of a peril occurring.  

   - Types of Hazards:  

     - **Physical Hazards:** Tangible factors like a faulty electrical system.  

     - **Moral Hazards:** Behavioral risks, like exaggerating claims.  

     - **Morale Hazards:** Carelessness, such as leaving doors unlocked.  


---


### **Risk Assessment in Insurance**  

Insurers assess risk to determine:  

1. **Premiums:** Higher-risk individuals or properties may be charged more.  

2. **Policy Terms:** Coverage limits and exclusions are set based on the risk profile.  

3. **Insurability:** Some risks are deemed uninsurable if they are too unpredictable or catastrophic.  


---


### **Risk Mitigation in Insurance**  

Insurance doesn't eliminate risk but helps manage it. Risk mitigation strategies include:  

1. **Risk Transfer:** Transferring the financial burden to an insurer by purchasing a policy.  

2. **Risk Reduction:** Taking steps to lower the likelihood or severity of risks (e.g., installing smoke detectors).  

3. **Risk Retention:** Accepting minor risks (like small deductibles) to save on premiums.  


---


### **Examples of Risk in Different Insurance Types**

- **Health Insurance:** The risk of illness or injury leading to medical expenses.  

- **Auto Insurance:** The risk of car accidents or vehicle theft.  

- **Life Insurance:** The risk of premature death and its financial impact on dependents.  

- **Property Insurance:** The risk of property damage due to natural disasters or theft.  


---


Understanding risk is the cornerstone of insurance. It enables insurers to design policies that protect individuals and businesses while ensuring sustainability for the company.

Why lips crack in winter, how to avoid?

 Why lips crack in winter, how to avoid?


In the winter season, the skin starts to become dry, so if the skin is not moisturized, it starts to crack. The same problem occurs in the skin of our lips. Chapped lips are common in cold weather, which is a problem for many people.


Despite taking various measures to avoid this problem, many times the problem of chapped lips remains. Some people have cracked lips, bleeding, and even have trouble eating.






Why do lips crack in winter?


In winter we drink less water. Due to the lack of water in the body, the lips become dry and crack easily. Since the air is dry in the winter season, the body does not get the moisturizer it gets from the air. Because of this, the lips are more chapped.





Staying in the sun for a long time in winter can also make the lips dry, because the sun's rays remove the moisture from the lips and the lips crack. When the lips are dry in winter, we touch or lick them frequently, due to which the lips become more dry and chapped. Lips can also be chapped if you use sticky or cosmetic products that irritate your lips.


What to do if the lips are cracked?


Use petroleum jelly to soften the lips. By using it, the moisture of the lips is maintained and the lips do not crack.


Lips should be protected from the sun like any other part of the body. Therefore, it is advisable to use a lip balm with SPF. It also provides protection from damage caused by ultraviolet rays.


The skin of the cracked lip should not be scratched. If the lips are chapped, the skin on the lips will look dry. Dead skin on the lips should not be removed by scratching with fingers or nails, doing so may cause injury.


Ways to avoid chapped lips


It is important to keep the body as well as the skin hydrated. Moisturize the skin for hydration, drink enough water. It is necessary to drink at least two to three liters of water a day. Do not touch your lips frequently. Dirty hands can cause infection in the lips. Also, the lips may become more dry.


When the lips become dry, many people move their tongue around the lips. But this should not be done, because doing so will make the lips even more dry.


In winter, lips are affected a lot due to cold wind, sunlight and many other reasons. So before going out you should apply lip balm or any moisturizer on your lips. Before going out in the cold, you should wear a mask to cover your lips.

How to check fresh meat in Dashain?

 How to check fresh meat in Dashain?


Many meat shops in Nepal are not constructed and operated scientifically. Due to carelessness there is a risk of bacterial infection in the consumer, the larvae of lice entering the body and different types of diseases. Therefore, you have to pay special attention to some things when buying meat.


Everyone should consider the danger of getting disease instead of nutrition from meat if they get spoiled meat while buying meat. Therefore, consumers should be aware of these things for healthy meat.






Color: Fresh meat should be dark natural color. For example, beef, pork, and chicken are usually dark red, pink, and white, respectively. However, if the color of the meat is light purple instead of red, it means that it has been exposed to oxygen. But it is not dangerous or harmful.


Smell: This is considered to be the easiest way to check the freshness of meat. Fresh meat does not have any kind of smell. There is no particularly strange smell. Strange odors can often be sour, bleach, ammonia or fishy.





Touch: You can also know the quality of meat by touch. Fresh meat is hard to the touch. To check whether the meat is fresh, you should gently press the meat with your fingers. If the meat is fresh, then after a while the meat will return to its original shape, no fingerprints will remain on the meat. If it is not fresh meat, it will have fingerprints on it. If the meat feels slippery to the touch, it is a sign that the meat is rotten.


Check for excessive 'Drop Loss': Drop loss refers to the liquid material that comes out of the meat due to gravity during storage and handling. If the drop loss of meat is excessive, it indicates that the meat is not fresh.

Why do cholesterol patients increase in hospital after Dashain?

Why do cholesterol patients increase in hospital after Dashain?


We understand Dashain as a festival of eating and drinking. That is why Manlagdi is eaten at this time. Fish, meat and alcohol are mandatory during Dashain.


Even those who don't drink at other times drink because it's a festival. Drunkenness was a better excuse. They sit and drink from morning till midnight.






On top of that, Sitan was also wanted. Grilled, fried, spicy, bitter, sour meat. Dalmot, chips. What is the habit of most of them is to take vinegar after drinking alcohol.


Such foods may not have an immediate effect. However, with the onset of winter, the number of patients in the hospital begins to increase. Most of them have cholesterol problems. After all, why did they have bad cholesterol? The uncontrolled eating of the same Dashain is one of the reasons behind this.





What happens when cholesterol increases? Why does it increase? Let's understand it in common language.


Cholesterol is a layer of fat in our body. Cholesterol is necessary for proper blood flow in the blood vessels and the structure of the body's cells. However, if the amount of cholesterol in the blood is more than required, it accumulates in the blood vessels, liver and heart.


Blood collects in the blood vessels and narrows the blood vessels. This is why the blood flow is not good. What this does is increase the risk of stroke, heart attack and heart disease.


This problem is mostly seen in people with heart problems and high blood pressure. However, it does not mean that it is not seen in others.


Cholesterol is such a problem, the early signs of which do not match anything. It suddenly causes problems. Its general symptoms can be seen in anyone. Like white spots appearing around the eyes, black spots appearing on the back of the neck. However, in most cases, this problem is not detected without testing.


When the problem increases, it becomes difficult to handle it. Therefore, it is advisable to find preventive measures before such a problem occurs.


What to do now?


Be alert and take necessary precautions before problems occur. For this, some conditions must be followed.


- Reduce the consumption of red meat. Instead of red meat, white meat and fish can be consumed.


- Do not eat too much ghee, butter, cheese and animal fats.


- Cholesterol contains triglycerides. As carbohydrates increase the amount of triglycerides, eat such foods as little as possible.


- Sugary foods are high in carbohydrates, so eat as little as possible.


- In case of heart disease and high cholesterol level, take related medicine regularly.


- Consuming more fruits and green vegetables than meat.


- Eating less fat and skinned meat.


- Full sleep.


- Don't drink alcohol. Even if you do, consume very little.


Consuming high amounts of fibrous and fiber-rich foods.


Along with diet, you should also pay attention to exercise. At least five days a week you should walk briskly for 30 to 45 minutes.


A medical emergency situation


Eating alcohol and meat indiscriminately increases cholesterol. Apart from that, there are also many people who come to the hospital with a bone stuck in their neck. People are not alert and alert when they are drunk. At that time, when they eat bones with meat, there are many cases of them getting stuck in the throat. This is a medical emergency. In such a situation, if not treated immediately, it can lead to death.


Likewise, people with heart problems, high blood pressure, and those taking blood thinners can also be at risk from uncontrolled eating.

 

Central Themes of Radical Feminism in Sexual Politics

Central Themes of Radical Feminism in Sexual Politics


Radical feminism, particularly as articulated by Kate Millett in her seminal work *Sexual Politics*, provides a critical framework for understanding women's subordination through the lens of sexual politics. Millett's analysis focuses on the intersection of power dynamics and sexual relationships, arguing that patriarchy is not just a social structure but a pervasive political system that governs all aspects of women's lives.



## Central Themes of Radical Feminism in Sexual Politics


### 1. Patriarchy as a Political System


Millett argues that patriarchy operates as a political system that enforces male dominance over women. She posits that this dominance is maintained through cultural narratives, societal norms, and institutional practices that privilege men while subjugating women. According to Millett, sexual politics encompasses all power-structured relationships where one group exercises control over another, making it essential to understand how these dynamics manifest in everyday life.


### 2. Sexual Relationships and Power Dynamics


In *Sexual Politics*, Millett examines how sexual relationships are inherently political. She critiques the portrayal of women in literature and media, highlighting how male authors often depict women as passive objects of desire, reinforcing their subordinate status. By analyzing works from authors like Norman Mailer and D.H. Lawrence, Millett illustrates how these narratives perpetuate violent and misogynistic attitudes toward women, framing them as compliant and subservient.


### 3. The Social Construction of Gender


Millett emphasizes that gender roles are socially constructed rather than biologically determined. She argues that societal expectations dictate behaviors deemed appropriate for men and women, which are then internalized by individuals. This socialization process contributes to the normalization of women's oppression, making it seem natural rather than a product of systemic inequality.


### 4. Critique of Traditional Family Structures


Millett critiques the traditional family unit as a microcosm of patriarchy, where power imbalances are reproduced. She argues that the family serves to reinforce gender roles and maintain male authority, often at the expense of women's autonomy and freedom. This perspective aligns with radical feminist views that seek to dismantle patriarchal institutions to achieve true liberation for women.


### 5. Call for Revolutionary Change


Radical feminists like Millett advocate for a fundamental reordering of society to eliminate male supremacy. This involves not just reforming existing structures but challenging the very foundations of patriarchal power. Millett's work encourages women to recognize their oppression and mobilize for collective action against the systems that sustain it.


## Critique of Western Feminist Approaches


Millett's critique extends beyond literary analysis to challenge broader feminist movements that may inadvertently reinforce patriarchal structures:


- **Reductionism**: Millett warns against reducing women's oppression to mere economic or legal issues without addressing the underlying sexual politics at play. She argues that understanding the complexities of power dynamics is crucial for effective feminist activism.


- **Cultural Representation**: By focusing on how women are portrayed in literature and media, Millett highlights the importance of cultural narratives in shaping societal attitudes toward gender. She calls for feminist critiques that address these representations directly rather than accepting them uncritically.


- **Intersectionality**: While Millett's work primarily addresses gender and sexuality, it also lays the groundwork for future feminist theories that incorporate intersectional analyses, recognizing how race, class, and other factors intersect with gender to shape experiences of oppression.


## Conclusion


Kate Millett's *Sexual Politics* serves as a foundational text within radical feminism, articulating how sexual politics reflects broader systems of power and oppression. By examining the interplay between sexuality and power dynamics, Millett critiques patriarchal structures and calls for revolutionary change to achieve true gender equality. Her work remains influential in contemporary feminist discourse, urging activists to confront not only legal inequalities but also the cultural narratives that perpetuate women's subordination in society.

Comparison of Cross-Sectional, Cohort, and Panel Data in Sociological Research

Comparison of Cross-Sectional, Cohort, and Panel Data in Sociological Research


### Comparison of Cross-Sectional, Cohort, and Panel Data in Sociological Research


In sociological research, the choice of data type is crucial as it influences the research design, analysis, and interpretation of results. Cross-sectional, cohort, and panel data are three fundamental types of data, each with distinct characteristics, advantages, and applications. Below is a detailed comparison of these data types, along with examples of when each would be used in sociological research.



### Cross-Sectional Data


**Definition**: Cross-sectional data is collected at a single point in time, providing a snapshot of a population or phenomenon. Researchers analyze various variables simultaneously without any follow-up.


**Characteristics**:

- Data is collected from multiple subjects at one time.

- Useful for identifying patterns, associations, and prevalence of characteristics within a population.

- Quick and cost-effective to gather.


**Example of Use**: A sociologist might conduct a cross-sectional study to assess the relationship between social media usage and anxiety levels among teenagers. By surveying a diverse group of teenagers at one time, the researcher can identify trends and correlations but cannot establish causality.


**Situations for Use**:

- When the research objective is to understand the current status or prevalence of a phenomenon.

- To generate hypotheses for further research.

- In studies where time constraints or budget limitations exist.


### Cohort Data


**Definition**: Cohort data involves tracking a specific group of individuals (a cohort) who share a common characteristic or experience over time. This data type allows researchers to observe changes and developments within that group.


**Characteristics**:

- Focuses on a specific cohort, such as individuals born in the same year or those who experienced a particular event (e.g., graduating from college).

- Data can be collected at multiple time points, allowing for longitudinal analysis of the cohort.


**Example of Use**: A researcher might study the long-term effects of childhood obesity by following a cohort of children from ages 5 to 25. By measuring various health outcomes at different ages, the researcher can analyze trends and impacts over time.


**Situations for Use**:

- When researchers want to study the effects of a specific event or experience on a group over time.

- To understand generational differences or trends.

- In studies that require tracking changes in health, behavior, or attitudes within a defined group.


### Panel Data


**Definition**: Panel data, also known as longitudinal data, involves collecting data from the same subjects over multiple time periods. This allows researchers to analyze changes at the individual level while also comparing different individuals at the same time.


**Characteristics**:

- Combines elements of both cross-sectional and time series data.

- Enables the analysis of dynamic changes and causal relationships.

- Can control for unobserved variables that do not change over time within subjects.


**Example of Use**: A sociologist studying the impact of a new educational policy might collect data on student performance, attendance, and demographic information from the same group of students over several years. This allows for observing how individual performance evolves in response to the policy.


**Situations for Use**:

- When researchers aim to analyze changes over time and establish causal relationships.

- To control for individual-level variability and unobserved heterogeneity.

- In studies requiring detailed insights into the dynamics of social phenomena.


### Summary of Differences


| Feature               | Cross-Sectional Data                      | Cohort Data                           | Panel Data                               |

|-----------------------|-------------------------------------------|---------------------------------------|------------------------------------------|

| **Data Collection**   | Single time point                         | Multiple time points for a cohort    | Multiple time points for the same individuals |

| **Focus**             | Snapshot of a population                  | Specific group over time              | Changes within individuals over time     |

| **Analysis Type**     | Correlational, descriptive                | Longitudinal, trend analysis          | Dynamic analysis, causal relationships    |

| **Cost and Time**     | Quick and cost-effective                  | More time-consuming and costly        | Most complex and resource-intensive      |

| **Causality**         | Cannot establish causality                | Can suggest causal links              | Can establish causal relationships       |


### Conclusion


Choosing between cross-sectional, cohort, and panel data depends on the research questions, objectives, and available resources. Cross-sectional data is ideal for quick assessments and hypothesis generation, cohort data is suitable for studying specific groups over time, and panel data provides in-depth insights into individual changes and causal relationships. Understanding these differences allows sociologists to design effective studies that yield meaningful and actionable insights into social phenomena.
