I don’t need male friends Are men subordinates or bosses? Women can be friends by Nada 20230925

Hello. It's tears. Today we're talking about friendship between men, or friendship between men and women. Please understand that this is my personal opinion as it may be based on my own biases.

I don't think I need male friends. Of course, if you're a student, it might be nice to have same-sex male friends. You can say that this is because being a student is a special period where everything is forgiven just by studying. However, some people become so busy with work that they have no time to hang out with friends. I work so hard that I don't have time to study or play even on holidays. There will be many people like this.

I believe that the majority of relationships among working adults are work-related. Even if you work for a good white company, you will spend 8 hours a day, or 2000 hours a year, at work. For this reason, working adults are increasingly involved in relationships between their superiors and subordinates at work. Of course, there are also contemporaries. They may have started working at the same company in the same year and may have a relationship where they occasionally drink alcohol. After 5 or 10 years, you should be able to figure out which of you is on the path to advancement.

"Ah, that guy from my class is more successful than me." If that's the case, a hierarchical relationship will likely emerge among the classmates. I think friendships between men of the same sex should never be underestimated. Even if a person is very popular with women, if something really bothers them, the person who will reach out to them may be a man of the same sex. On top of that, I think it's more rational to think of men in terms of hierarchical relationships rather than as equals. This is because in order for men to be equal, they need a special relationship, such as when they were students at the same university without any job title.

However, once you start working, you'll find that you'll find a variety of things to compare with, such as whether that person's company is bigger or whether he's already a section manager. In my case, I generally don't look down on others or look up at them. Everyone is equal. However, as members of society, there is always something called status. So, when we compare them based on their status, we end up thinking that I'm better than them based on a certain standard, or that he's not as successful as me. Based on that standard, the other party probably feels the same way.

On top of that, men of the same gender will naturally compare themselves. If this is the case, a hierarchical relationship will emerge. But what about women of the opposite sex? I think it is difficult to compare men with women in terms of which career path is best for them. Even if women are promoted, it doesn't necessarily mean that they recognize the equality of men and women these days or their abilities. Today's society is definitely male-dominated. Therefore, even if women are promoted higher in the ranks, you should not honestly think that it is because of a difference in ability. This may be the reason why men and women tend to have a special hierarchical relationship.

Friendship between men and women is simple. The question is whether you can tolerate having a partner whose boyfriend is the other woman. If a woman doesn't care if she has another boyfriend, then a friendship between a man and a woman would be possible. However, this is often the most difficult aspect of friendship between men and women.

I would like to summarize my opinion here. Personally, I don't look down on anyone or look up at anyone. Everyone is equal. However, depending on the roles given by society, hierarchical relationships arise. It is up to each person to set aside this hierarchical relationship and decide whether they still see it as equality or whether a hierarchical relationship exists. On top of that, it's up to you whether you can ignore romance and get involved with a woman of the opposite sex. In the end, each person's opinion is different, and that's what allows society to function. This is one conclusion for me. What do you think. See you soon.

The neck can be easily adjusted by cooling or warming it by Nada 20230925

Hello. It's tears. The summer months were hot and humid. I also spent the summer indoors with the air conditioner on as much as possible. Until last year, I was able to get through it with just a fan, but this year I couldn't get through it with just a fan.

The hottest time of the day is around 2pm. If you have to walk outside at this time of day, you'll be drenched in sweat. So, I think you can try the following method to avoid sweating as much as possible. It means walking while holding a cold plastic bottle around your neck. Of course, if you have a car, it may be best to travel by car, but if you live nearby, you may also need to walk.

At that time, you can have juice or tea, but if you buy something cold from a vending machine, you can comfortably hold it against your neck as you walk, and you will sweat less. By cooling your neck, the blood flow in your neck cools down, which helps keep you cool.

On the other hand, in winter, placing a warm plastic bottle on your neck will warm up the blood flow in your neck and help you avoid the cold. You can adjust the temperature of your neck by wearing a muffler, etc. around your neck. If you can't help but feel hot or cold, you may be able to maintain a comfortable state by paying attention to the temperature of your neck. See you soon.

When the formula A = B and the formula C = D are mixed, an expression that does not exist in this world is born by Nada 20230923

Hello. This is Nada.

Suppose A=B and C=D. Each expression exists independently, but they may have completely different properties. Create a new equation by adding or subtracting both equations. When A+C=B+D, if there is something for which B+D=S, then A+C=S and a new formula is created. Lanchester's strategy states that under the same conditions, if the difference in soldiers x weapons is 3 times the difference, you can win the battle. Here, A: military power + B: weapons = C: military power. If D: Strategy = E: Information, then A+B+D=C+E can be interpreted to mean that soldiers with weapons and strategies have an advantage in fighting while making full use of information warfare.

To use another example, if there are two elements, A: get angry and B: enjoy, then A+B=(enjoy being angry). For example, getting angry at someone you just started dating may be a more pleasant memory than eating pudding. If B: Enjoy = C: Rejoice, then A+B=A+C. Strictly speaking, enjoying and being happy have different meanings, but in this case, (A+B) being angry and having fun = (A+C) being angry and being happy.

A profit of 23% is a sign of good quality for a company by Nada 20230920

I think it is good for companies to aim for a profit margin of 23% or higher. In fact, if you rewrite the formula sales - expenses = profit as follows: expenses + profits = sales, you will find that higher profits reduce costs. The price index is a very exciting number, and if it is 30% off or 50% off, it will be easy to attract customers' attention. Prices have a strong incentive, just as half-price lunch boxes bring savings to some people. If there was a way to set prices better, it would be an invention. The above formula of price = average cost also works well in an excess demand economy called Say's law. However, in markets where there is unsold stock or inventory, or where profits are not zero, by adding an inventory term and a profit term to the formula (Price x Sales Quantity = Production Volume x Average Cost), it is possible to confirm the situation more realistically using the formula. become. By setting such a price formula and applying it to various products, more rational pricing becomes possible. I would like to think carefully about whether it is reasonable to set prices at 30% or 50% if the products do not sell as well as they are priced at supermarkets. Whether it prospers or declines depends on the price. Isn't pricing the best place to show off your management skills?

p = MC can be said to be a zero price without profit by Nada 20230920

I would like you to imagine the price of the products that the company sells. There are many different types of companies. All kinds of companies, from monopolies to perfectly competitive companies, struggle with pricing their products. I would like to take up the following formula. Sales - expenses = profit. It seems like an obvious formula without even bringing up accounting. To see the flow of money at an atomic level, it's a good idea to look at sales, costs, and profits per product. Let's now consider a perfectly competitive market, a market where profits are zero. From the above equation, if profit is set to zero, sales - expenses = 0, and sales = expenses. When mass producing a certain product, sales = price x sales quantity, cost = production volume x average cost, and the formula can be broken down. There is a relationship between sales volume and production volume, where production volume is the upper limit of sales volume, and if sales volume = production volume, there will be no unsold items, in other words, the product will be sold out. If sales volume = production volume = 1, price x sales volume = production volume x average cost, so price = average cost. Since price = marginal cost, or p = MC, is an important equation in microeconomics, it is consistent with microeconomics if marginal cost = average cost. Of course, in the real economy, companies operate to earn profits.

Music Image Training by Nada 20230920

I think music, like anything else, has its tricks. Put pressure on your throat or put pressure on your tongue. I've heard that singers practice for one or two hours a day, but I think it takes a lot of effort to become good at voice training, which only involves singing in a fixed way. What I would like to suggest here is a method of practicing without speaking out loud using image training. Since you don't have to use your voice, you can practice singing while taking a walk or doing something else. When it comes to work, you have to make a schedule, do simulations, and act strategically. By practicing while imagining the singing voice of a singer who is better at singing than you, you can improve quickly. Whether it's business or academics, you need some kind of vision, and if you can visualize that ideal image, your goal will be right there. There are probably many ways to practice, but the best way may be to find a practice method and singing style that suits you.

Formulas in which composite numbers appear and formulas in which 1mod4 primes appear by Nada 20230919

"Equations where composite numbers appear and equations where 1mod4 prime numbers appear"

Hello. It's tears.

A composite number is a product such as axb, and can be expressed as axb=cxc-dxd. A prime number never appears in cxc-dxd unless either a or b is 1. If you want to see the opposite number, there is a way to reverse the plus and minus numbers. Even if you change cxc-dxd to cxc+dxd, only some numbers that have not appeared before will appear, and all of Othello's white pieces will not become black. However, some of the swapped values ​​cover 1mod4 prime numbers. Generally, when you divide an odd number by 4, the remainder is either 1 or 3. Included as part of cxc+dxd. However, on the contrary, 3mod4 does not appear at all. Since 1×1=1 and 3×3=9=1mod4, only 1+1=2mod4.1+0=1mod4,0+0=0mod4 will appear. No matter how much you calculate cxc+dxd, it is inevitable that 3mod4 will not appear. Now, axb+cxd (cxd in this case has nothing to do with cxc+dxd) produces a large number of prime numbers. For this, a, b, c, and d must be relatively prime. I hope everyone will look into this mutually prime factor. If you have the time and are interested, you won't be disappointed. Also, if I have a chance, I will write about each other.
