If I had to describe myself in one word, I would be a workaholic tuna person! If you get a skill, you won't have to worry about money when the time comes.

Hello. This is Tenmei Watanabe from Seito Medical School. This time, the theme of the survey is "How would you describe yourself in one word?" Below are links to recommended articles.

If I had to describe myself in one word, I think the word workaholic would be appropriate. I have been working in a variety of jobs for over 10 years since I entered the workforce. My work is an extension of my hobby, so I feel self-satisfied with the fact that I'm socially productive.

A working adult's job may mean graduating from university (high school), getting a job, and performing duties as directed by the boss.

I consider this blog to be both a hobby and a job, and I believe that if this blog becomes popular in the future, I will be able to recoup the effort I have put into the blog so far.

In that sense, I'm not as old as someone in my 20s, but I can say that I'm like a tuna who dies when I stop swimming. When I was in my 20s, I tried to take ownership of my work and pushed myself hard, but now that I'm in my 30s, I've started to feel like I should slow down a little.

Whether it's work or research as a hobby, I'm happy as long as I'm getting the results I want. To produce results, you need time to concentrate, and you also need the understanding of those around you.

If I had to describe myself in one word, I would say that I am a workaholic, but in terms of my personality, I would say that I am more principled than serious. In other words, he is a philosopher of life.

"Why not use your special skill as a workaholic to work your way up the ladder?" A hermit who has mastered the working world will be able to give me some advice. However, I can say that the work that I am passionate about is more of a hobby than a job as a member of society.

``If you become a workaholic, you'll become a pickled tuna soaked in an energy drink!!'' That advice is true. In fact, I felt sore from caffeine.

Also, staying up all night isn't good. The synonym for workaholics is staying up all night for 3 days, but in the morning after doing 3 consecutive sessions, you can feel the living blood flowing through your body. Once again, I don't recommend it.

In particular, even though I didn't get any ground-breaking results when I won three times in a row, I felt like, ``I did it! It's as exhilarating as winning Chomolangma.''

I also have a vague feeling that it's better to stop being a workaholic when you're in your 40s or 50s. In fact, if you're in your 40s, you can still be a well-oiled corporate warrior. Force should work.

However, from my 20s until now, when I am in my mid-30s, I have worked hard to train myself in the name of work, so I am sure I can fly. Although it is a low-altitude flight, it can be said that there is a big difference between being able to fly and not being able to fly.

There are amazing people in the world. Some people say that there is no big difference between managers, but there is something different about those who have truly mastered something. There is an overwhelming difference in experience points, so when we try to compete, we end up losing every time due to Sundae's difference.

It's easy to understand when you think of chess or shogi, but a really strong person can make it look like a last-minute battle and win every time, or they can make a last-minute loss to their opponent in order to make a difference.

Just as you can speak techniques according to the level of the other person, you can do the trick of adjusting to the level of the other person because that level is a passing point that you passed a long time ago.

Returning to my story about workaholics, there is a possibility that workaholics will eventually become one of those who have mastered their work. This is because they are trying to acquire work techniques that are more efficient and effective than other members of society by practicing hard at work.

My job includes writing for this blog, but if I start making money from writing, I don't think it's a problem to call myself a professional.

I would like to write about my strategy here, but I am running this Clear File Seito Medical School blog, the English version of the Seito Medical School blog, and a thread on SNS.

You can monetize your blog by posting advertisements such as Google AdSense, but I am not very active when it comes to advertisements. This is because we are not actually selling the actual item.

Therefore, I think it would be great if I could write an e-book and sell e-books and later paper books to interested readers. Since you will probably have to pay your readers, you can expect that it will be more difficult to make money from e-books than from advertising revenue.

I think I will talk about this story again in a separate article. For me, work is a role-playing game. I realized that the real pleasure of life is to keep taking on new jobs and investing a lot of your precious time so that you can earn money even if you become penniless.

Having a job that allows me to earn money anytime, even just writing this blog, will be a pillar of my future. I think our readers have a variety of skills. Rather than watching TV or playing games every day, it may be the fruits of your efforts that will help you in the event of an emergency.

I wish my readers success. It was from Watanabe, a workaholic. Let's meet again! ! See you soon.

When I was a kid, the virtual world was the world of video games! The current virtual world is a blog that is a game of reality

Hello. This is Tenmei Watanabe from Seito Medical School. Until now, virtual worlds were the worlds inside video games. I have also been obsessed with video games since I was a child. Watanabe is a gaming addict, but by the time he reached his 20s, he had completely stopped playing games. Well, this time I would like to think about the virtual world as it is a medical school rewrite. Below is a link to the previous rewrite article.

I don't deny games (I used to play a lot when I was a kid), but when I look at games from a certain angle, I realize that people who play video games or mobile games are doing something wasteful. I feel that way.

The good thing about video games is that you can experience a world that doesn't exist in reality. I believe that there have been games in the past where all the residents of a village were standing on their heads. When I find myself in such a strange, complete world in a different way, I feel like I am one of its inhabitants.

In the game, you steadily earn coins in the game, but the effort of earning coins, accumulating experience points, and leveling up is fun at the time, but when you look back on it after you get bored with the game, You may feel like you were wasting your time.

The reason I have such a cold view of games is that I was also a game geek, and looking back now, I wonder if I really needed the time I spent playing games when I was a kid.

Even if my life were to go back to square one, I would still be obsessed with gaming until I was 20 years old. I think it would have been more meaningful if I channeled that effort into more practical things like studying and gaining valuable experiences.

Of course, I'm not negative about my children playing games. The feeling you get when playing games is important even when you grow up and become a member of society. That fun, immersive experience is necessary if you want to become an adult who understands jokes. This is true whether it's a manga or a sports club.

I think my childhood experience working on games was necessary. The people I want to like are people who play games even after they grow up. Maybe it's a matter of values, but I think it's better to prioritize things like getting qualifications, falling in love, and playing with friends instead of playing games in order to earn real money and gain experience points. I feel that I am indebted to you.

Of course, I'm talking about this because I'm anonymous on the Internet, and I wouldn't go out of my way to say this to the person face to face in real life. This is a so-called story only here. When you grow up, you understand more about society than when you were a child, and I think it's wiser to use your time in ways that leave something behind, rather than wasting it on games that leave you with nothing.

Up to this point, I have been talking about my values ​​such as thinking, feeling, and thinking, but instead of playing video games, I am talking about whether it would be more interesting to think of reality as a game and invest time in real things. . Collecting money and gaining experience points in real life is so much more fun than playing video games, but from a distance, I think it's a waste when I see adults enjoying video games.　

For me, games are blogs and research hobbies, but as someone who played a lot of video games in my teens, I can say that they are much more exciting and interesting than video games. . Let's stop talking about video games.

Now, blogging is a current game, but blogging is also a virtual world. It's an internet world, and unless we actually drink together until we're hungover at an off-line meeting, it can't be called reality. Of course, the money generated from advertising revenue is real money, not game coins, but if you want to be anonymous, you can remain anonymous forever.

A virtual world may seem like a world that has no contact with the real world, but anything that is called virtual can continue to be virtual because it is connected to things somewhere.

One of my favorite movies is an animated movie called ``Summer Wars,'' and you could say that Summer Wars is also a movie about the connection between the virtual world and the real world.

Of course, if I remain anonymous on my blog, it will remain a virtual world for me. However, a blog is virtual in the sense that something like a computer or smartphone connects me to the blog. If you want to make it even more realistic, I think it would be a good idea to reveal your real name on your blog and become a celebrity.

It is up to you to decide whether to remain in the virtual world or to make it into the real world. This is not a story about how you should rule as the creator of the world, but a story about whether you can become a celebrity by succeeding at games such as blogging.

In that sense, unless you become a professional gamer in video games like e-sports, it seems like you have almost no chance of becoming a celebrity like blogging or video streaming. It can be said that you are more likely to be socially successful if you invest your time into real-life games rather than video games.

I think it's important to master everything. This is because dedicating several years to becoming a leading expert in a particular field is an important experience for living in society at large. Once you climb a reasonably high mountain, it becomes easy to climb other mountains.

You may climb one mountain many times, but you will gain more experience in life by climbing other mountains as well. If you view the virtual world as a game world, then mastering one virtual world will lower the hurdles to mastering another, allowing you to knock down the lowered hurdles and aim for the top of another mountain.

In the article before the rewrite, I concluded, ``The virtual world is just a place to have fun, and if you want to get financial benefits, you need to link it to the real world.'' In order to earn money, whether it's through advertising revenue from your blog, you'll need to write down your name, address, bank account, etc.

If you only have a free blog and don't want to expose your personal information, you can leave the virtual world of your blog as a virtual world and not link it to reality. In other words, the only relationship you have is your computer or smartphone and your blog.

In order to receive monetary rewards in real games, you will have to deal with the risk of personal information. Recently, there are singers who remain anonymous, and we may see a future where anonymity is seen as a benefit. Things in the world are impermanent. that's all. Let's meet again. See you soon.

Where is the virtual world headed? Virtual Bitcoin is also linked to things 20230314

This is Watanabe, the blog owner. These days, everything has the word "virtual" attached to it. Virtual reality VR, virtual currency, etc. As the game-like world expands, what should we focus on? This is just one idea.

・The virtual world needs to be linked to the real world! Bitcoin is also linked to things

I dream of taking out coins from a video game! It's up to you to make it a reality!

　If you think about it, the virtual world up until now was the world inside video games . When I was a child, I was also a gaming idiot who only played games. In the world of video games, there are many different stories, and I think most of the stories involve the main character we control playing an active role.

<Related articles>

Do you have the courage to complete your mission? ? You have enough time in your life, but how do you use it?

For example, the obsession of a weirdo! Attachment to normality robs eccentrics of their abilities! ?

　When I played video games, I desperately collected in-game coins and experience points. I think most of the people in the forest were like that too. It seems that some of them were strong enough to take on a time attack to clear it in the fastest time.

　In games like RPGs, the idea that if you put in the effort over time, you will eventually see results has greatly shaped who I am today. However, no in-game coins or experience points remain once you clear the game. Watanabe had many dreams during his sleep about how he could somehow bring the huge amount of in-game coins into reality . It's a very occult story, but I think there are many people who can relate to it.

　In the end, all Watanabe was left with was the joy of completing the game and a few lessons learned . There is nothing left that can be seen.

"Watanabe-kun, you're expecting too much from games. Games are for virtual experiences. The secret of games is to do whatever you want in virtual reality! Yay!"

　that's right. Watanabe had too high expectations for video games. Video games are virtual reality, not reality. However, recently it seems that the boundaries between virtual reality and reality are disappearing .

　The fact that blogs are also a type of virtual reality confronts us with a certain reality.

“The blog also has off-line meetings, so it’s not just about writing. Let’s all have off-site meetings and be groggy! Puhyaa.”

　In other words, it is up to the person blogging whether to make it virtual or real .

　Even if it is a so-called virtual reality game, such as a recent smartphone game, the in-game coins can be sold to someone who wants it. In the end, the question comes down to what is virtual?

　Until now, virtual reality was just a place to have fun.

"Let's enjoy BBQ with everyone in the forest. We'll feed them some imaginary bone-in meat and make them friends! Although we can't buy marbled meat."

　However, depending on your own judgment, you can link to reality and become happy or unhappy.

　I think it's not that risky to become famous just by making anonymous comments on the Internet. However, I think there is a lot of fear and anxiety when it comes to having to disclose your personal information in order to link it to reality .

"Watanabe. Show your face. You must have been popular when you were a student. If you're not lying, prove it. I'm the god of virality ♡"

　In fact, everyone in the forest probably won't know whether his surname Watanabe is his real name or not. He may also be using a fake name. However, even if it were his real name, some of his friends might wonder, ``Why does Watanabe use his real name? He probably doesn't want to show his face.It's contradictory.''

　Watanabe is a man full of contradictions, and he himself doesn't quite know what he wants to do. Watanabe often avoids accountability by saying, ``We're considering it.'' It may not be a matter of accountability, but there are bound to be some readers who are not satisfied with it.

　What we can say at this point is that in some cases it may be linked to reality . You can reply that the use of the person's last name is a foreshadowing. In other words, it depends on the situation. In the end, it's an escape posture. I am a pathetic person. Well, this discussion has little to do with this article, so I'll stop for now.

The virtual world needs to be linked to the real world! Bitcoin is also linked to things

　Will the space called virtual reality continue to expand? One of Watanabe's favorite movies is ``Summer Wars . '' This movie depicts an incident that occurs when the RSA code that Watanabe is researching, which uses prime factorization, is broken and the real world and virtual world are linked.

　After all, a virtual world cannot exist on its own; it must be linked to the real world somewhere . Virtual currencies such as Bitcoin, which have recently experienced a resurgence, cannot exist solely as virtual currencies, and can be said to have meaning because of the practical benefits of being able to exchange them for things.

"How much money did Mr. Watanabe make from Bitcoin? You must have been paying attention to it from a very early stage. It's normal for working people to spend a little money, right?"

　I have known about virtual currencies since the beginning. I've thought about investing many times, but in the end I never got around to it. I had been looking at money for quite some time, and even before that, I was looking at real estate investment. Watanabe is very sensitive to the needs of his time. If I had invested right away, I could have built up a fortune in the hundreds of millions, but I don't want to invest because I'm too nervous.

　On this blog, Watanabe would like to share with everyone in the forest what he has noticed. Of course, we do not mediate financial products . That's because it seems like he needs some qualifications, and if he proposed without qualifications, it would have been a no-brainer.

　The same goes for legal matters, but the act of obtaining money for some kind of professional consultation may qualify . If you accept money without qualification, you may be arrested, so you need to be careful.

　So it was time to listen to Hotaru no Hikari with my friends. I thought about it for a day, and I think it would be a good idea to write a blog post to reach everyone in the forest.

　So far, the story has flown in many directions, but the virtual world is just a place to have fun, and if you want to make financial gains, you need to link it to the real world . However, linking is an act that involves great anxiety, and you need to be careful.

　I don't know if everyone wants to gain financial gain or not, but if you are a blogger and want to gain financial gain, it is better to think carefully before exposing your personal information to the real world. I think. I wish everyone good luck. See you soon.

What is a middle manager? I like being a coordinating leader, but I want to be a proactive leader.

Hello. This is Tenmei Watanabe from Seito Medical School. This time, I would like to rewrite about middle management as it is a medical school rewrite. Below is the pre-rewrite article.

Middle management. Hmm. I believe that the role of a middle manager is to provide a model for the workplace. In this blog, we believe that middle management positions are the key to communication and are necessary for creating a team atmosphere. If it's not my imagination, I feel that middle managers are the ones who take the initiative and work harder than anyone else.

Recently, there was a story on internet news about how a boss's role is to leave notes. I think it's a good idea to leave notes. By writing memos, the workplace will be clearer and more clear with instructions about who said what and how, and who should act in what way.

I'm basically the type of person who says, "Don't look at the trees, look at the forest, look at me!!", so my boss's role is to come to work earlier than everyone else and work more overtime than anyone else to make sure it's not wasted until the end. I am thinking. My way of thinking is rooted in the Showa era (I'm in my 30s), but I would say that I'm a proactive leader, where the boss works the hardest and the subordinates watch and follow the boss.

There are books that say that it is important for modern leaders to create a work environment, but above all, it is important for bosses to take the initiative to create valuable work and pass it on to their subordinates. I'm thinking.

Some bosses create unnecessary work, but the idea is that the boss's role is to find work that will contribute to sales, and it is the boss who asks his subordinates to do that work. If it is a normal business, it can be handled by the usual number of people. This is where the skill of a boss lies in finding new work that will improve performance.

It's also a really good way to improve your business. In any case, think of ways to make it better than the current situation. If business performance is improving, everyone is happy. When superiors improve their performance, their subordinates naturally strive to improve their performance as well. In other words, it is necessary to create a positive cycle.

Although he is a player-type leader, he does not simply handle his work casually. I take the initiative in my work, and while I'm at it, I even create a manual. Of course, it is necessary to delegate the creation of manuals to subordinates, but first, as a superior, you should show your subordinates an example. This is something I can do because I am a player-type leader.

After showing a basic example, have your subordinates try their best to find their own strategies through trial and error. In the article before the rewrite, I wrote that I was nervous about becoming a middle manager, but appealing to subordinates that I am doing my job is effective, and actually doing high value-added work, that is, contributing to sales. I'll find a job to do.

It's ok. A model case could be a boss who communicates in the latest fashion and brightens the atmosphere. However, I am a player who wants to take the initiative in not only creating an atmosphere but also increasing sales, so as a playing manager I am aiming for the star job of creating new jobs that will increase sales.

Once an employee has determined that a job will be profitable, he or she will create a manual and hand over authority to subordinates. Since the subordinate's performance will improve relatively easily, the workplace will be full of motivation, there will be no fruitless situation of holding each other back, and the subordinate will be willing to cooperate with the superior.

Of course, there are some people who don't want to work from morning until night, but if you can invest your time into work, you can work longer hours than others, have a decent amount of private time, and even take in new knowledge outside of work hours. I think it's an interesting experience.

In fact, it is a hardship to continue working like this until you are in your 50s, but in my opinion, you will gain more than you will lose even if you focus solely on your work during your 20s or until your mid-30s. People who keep their work and private lives strictly separate probably keep in mind that their lives follow the same rhythm from the time they get a job until they retire.

However, I think that this is where you should focus your efforts and that the results will not be bad if you concentrate on your work until you are in your 20s or mid-30s. Of course, there are things that can only be done when you are young, such as youth. Everyone has different values ​​when it comes to this, so it's hard to say what's good.

However, as a lifestyle, by devoting yourself to work in your 20s or until your mid-30s, you can gain a far greater advantage over others in terms of job title and experience.

I think I can recover even if I'm in my 40s. I think there are many working adults in their 40s who were unable to get a full-time job during the job hunting ice age. However, if you have a certain qualification, it is possible to earn more than the average annual salary.

If you don't make that little bit of effort and remain a non-regular temporary employee forever, you're the one who's taking chances unexpectedly. There are many opportunities for financial success with just a little effort.

To that end, I don't think you will regret it if you break away from being the same as everyone else and take on a challenge, such as studying hard for a one-year qualification. This is also a matter of values, so if you say that there is no point in getting qualifications, I won't deny it. If so, you can make other efforts to break out of the status quo.

This is a long story, but I think that the role of boss must have the heaviest burden and responsibility. That's why you can receive a lot of authority and good treatment as your boss. Some people may think that my way of thinking is old-fashioned. The idea of ​​``Can you work 24 hours a day?'' in the Showa era.

However, I have not experienced the Showa era, and I was born in the Heisei era. As someone who was born in the Heisei era, I am saying that there is some truth to the way people worked in the Showa era. It might be a good idea for you to aim to become a coordinating communication leader. That's the latest trend, and that's probably why I don't want to jump on the bandwagon.

Well, in conclusion, values ​​vary from person to person. The best solution may be to become a unique leader. That's all for now. Thank you for joining me in my story. Let's meet again. See you soon.

Let's solve the elliptic curve formula! Is the key to using Fermat's little theorem effectively? dragon blog

Hello. This is Tenmei Watanabe from Dragon Blog. Last time and the day before last, we explained two keywords for mixing in this article. In other words, it's about linear congruences and Fermat's little theorem. Do you remember? about me. It's not a friend I haven't seen in a while, but I would like to check these two keywords again.

Now, the first-order congruence expression is ``a and b are congruent modulo m.'' I'm trying to confuse the reader right away, but the expression a ≡ b (mod m) means that the remainders when a and b are divided by m are the same. In a fantasy world, my confusion strategy is to use things like evening primrose to solve confusion, but next time I'll use Fermat's Little Theorem, which is even more difficult.

Fermat's little theorem is an impregnable cipher with the formula a^(p-1)≡1 (mod p), where if p is a prime number, then a has a value from 1 to p-1 and becomes 1 with mod p. is. This time, I would like to talk about elliptic curve cryptography, so please think of the keyword "cipher" as a foreshadowing.

If you remember the name Euler's phi function from last time, you should remember that the correct name is a^φ(p)= 1 mod p. I'll put a link to the previous article here. I generally don't like to read articles, so if you fall and have to call an ambulance, I'll immediately transport you to a fantasy world and teach you a spell that will help you walk without legs. Is it a ghost? ? It's a little surreal (lol).

Well, I'll leave the idle gag here for the first time in a while. φ(p) is the number of numbers for which p is relatively prime. In other words, if p is a prime number 7, then there are 7-1 = 6, and if p is a non-prime composite number 9, there are 6, 1, 2, 4, 5, 7, and 8. In this case, φ(7)=6 and φ(9)=6, respectively. In other words, if we multiply a six times and mod p, then if a and p are relatively prime, we get 1 mod p.

Well, I've explained it quite quickly and sloppily so far. This is a review, but if you want to know more, please refer to the previous and previous articles.

Now let's talk about codes. This is a story about the demon world called codes, so please continue to enjoy my story if you like.

When you think of codes, some people may think of the runes of ancient civilizations. From the point of view of modern people, the letters used in the distant past are truly worthy of the name cipher. Let's code! !

Among the codes that are often used in modern times, the codes that are commonly used in modern times are the RSA code, which involves decomposition of prime factors, and the elliptic curve code, which uses elliptic curves. RSA encryption, which is a prime factorization code, is used to send credit card pin numbers to the bank where you have your deposit account. On the other hand, what do you think about elliptic curves even if you ask an elderly person? It is used in codes related to cryptocurrencies, which may be said to be.

This time, I would like to introduce a method to easily find a solution for this elliptic curve. Hello everyone? Primary congruence? Fermat's little theorem? What was it? Instead, please try to prepare and review the previous article. If you do that, you should be able to see the beginning of my story.

Now, what is the elliptic curve cryptography used in Bitcoin? First, look at the following formula: This time, it is not meant to be multiplied by x, but expressed as a single variable. Be careful! !

y^2 ≡ x^3 + 7 mod p

Those who think that complicated surgical techniques should not be used. Please rest assured. Since the values ​​of y and p are known in advance, only x is found. By the way, the symbol "^" means y^2, which is the square of y. In other words, y is multiplied twice. x^3 is x to the third power. In other words, it means x multiplied three times.

For example, let's say y=11, p=17. Actually, if you substitute the numerical values ​​and organize them, you will get the following.

11^2 ≡ x^3 + 7 mod 17

121 – 7 ≡ x^3 mod17

x^3 ≡ 114 mod 17 ≡ 12 mod 17

x^3 ≡ 12 mod 17　

Here, the remainder when dividing 114 by 17 is 12. One of the points is that the equation of this elliptic curve is a cubic congruence. In other words, it is a congruence of x to the third power. Let's apply Fermat's little theorem to this. Let's raise both sides to the 5th power.

x^(3×5) ≡ 12^5 mod 17

Since p=17 is a prime number, x^16 is 1mod17 if x and p are relatively prime. Then multiply both sides by x.

x^(3×5+1) ≡ x(12^5) mod17

x^16 mod 17 ≡ 1mod17 ① 

 (12^5)x mod 17 ≡ 248832x mod17 ≡ 3x mod17 ②

3x mod 17 ≡ 1 mod 17 ②＝①

Multiplying both sides by 6 gives 18x, which becomes 17x+x ≡ x mod17. For information on how to find 6 multiplied by both sides, please refer to Euclid's mutual division method in the previous article.

x mod 17 ≡ 6 mod 17 　

Answer: x = 6 mod 17

Calculation: x^3 ≡ 6^3 ≡ 12 mod 17

Therefore, you know the answer. Let's take another example. What if y=8,p=17?

8^2 ≡ x^3 + 7 mod 17

64 – 7 ≡ x^3 mod17

x^3 ≡ 57 mod 17 ≡ 6 mod 17

x^3 ≡ 6 mod 17　

x^(3×5) ≡ 6^5 mod 17

x^(3×5+1) ≡ x(6^5) mod 17

x^16 ≡ 1 mod 17 ≡ (6^5)x mod 17 ≡ 7776x mod 17 ≡ 7x mod 17

7x ≡ 1 mod 17

Multiply both sides by 5.

35x ≡ x ≡ 5 mod 17

x ≡ 5 mod 17

x^3 ≡ 5^3 ≡ 6 mod 17　

So, I know the answer. The key point here is Fermat's little theorem. The key point is that depending on how you use Fermat's little theorem, a^(p-1) becomes 1 mod p. No matter how many a's are multiplied together, it can be converted to 1 mod p depending on the conditions.

This time we explained how to find the answer for an elliptic curve, but for example, it is also possible to find a, b, and c for a given value of p for a^3+b^3+c^3=p. maybe. Let's do the math on this one ourselves. The difficulty level is quite high. Let's make a legend meeting.

How was it. It seems that the linear congruence equation and Fermat's little theorem are closely related, but by synthesizing them, I was able to discover a new way to solve the mathematical equation. This time I just mixed two keywords, but you might be able to find a more advanced way of thinking if you mix three keywords. This time is over. See you soon. 

Are you confused about moving from the field to middle management? Communication is for managers!

 This is Watanabe, the blog owner. Watanabe is a field worker who loves the field. However, he may also become a middle manager from now on. If you are a middle manager or a reader, you must have been confused when you were first appointed to your position. So, I would like to write about what happened when I was promoted from the field to middle management.

Management is communication! Skills are fundamentally different between managerial positions and those in the field.

　Middle management. Hmm. Starting a management career can be confusing at first . Up until now, I had been fulfilling my duties on-site, but now I am in a supervisory position, and my responsibilities have increased.

“After all, wouldn’t it be ideal for Watanabe to be ranked more like the second son of a 30-year-old boy than a middle manager?”

　I have brothers, but I don't have three brothers, so I admire having many brothers. However, when you have several subordinates who are like brothers, you have to keep track of everyone's situation at all times , which I think is difficult.

　In the first place, management can be said to have a completely different nature from any previous job. After all, it is necessary to create a comfortable working environment, and communication is important . There is also the position of playing manager, in which case you will be responsible for more complex tasks.

・What is Playing Manager?

　A playing manager is also a managerial position, so communication skills are required.

"Watanabe can't even manage his own blog properly, so can he even do his work in the field? First, let's try to master at least one of them! Kieeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeoooooooooooooooooooooooooooooo!"

　That's right. Watanabe prioritizes blogging, but due to various life circumstances, it has become difficult for him to keep up with his recent declaration of 2,000 characters per day x 5 articles. However, I am aiming for two articles a day. Quantity and quality are important.

　The story has gone off topic a bit, but if Watanabe continues to work hard, he may even get a promotion. At that point, you'll probably be confused. What should management do ? After all, I would like to say that it is a crutch to keep you from falling, and I think it would be a good idea to learn from Dr. Drager.

　This is Watanabe's strategy, but I think studying business administration will probably improve his morale. By the way, whether it's work or blogging, there are a certain number of people who want to hold back those who are working hard .

"He wasn't even bothered at all until recently. He's been on a roll lately! I'm the only one who should be on a roll! I am Ja*an!"

　It can be said that a manager's job is to deal with such people. I will say it again, one of the jobs of a manager is to prepare the workplace environment and maintain smooth interpersonal relationships in the workplace. Field work places emphasis on specialist skills, while managerial work places emphasis on communication such as interpersonal relationships. These two require fundamentally different abilities .

Watanabe meets anti-victim! ? 20% are allies, 60% are not interested and 20% are enemies! !

　Watanabe was not sharp today. Although Watanabe is usually very excited and the readers are also very excited, he seems to be the calm before the storm.

　It is possible that Watanabe was also exposed to the damage of antis for the first time.

"Be more humble, Watanabe! Well then, it's still going to be a kid's lunch. Don't you want to try steak with beer?"

　I wasn't told this directly, but I had a feeling it was something like that. However, Watanabe is not slowing down here! In fact, he plans to continue at his current pace. I declare it here.

　Watanabe's biggest purpose in blogging is to create a place for himself . Of course, the aim is to earn some pocket money, but there's no point in doing it if it's not fun. I hope I can only hang out with people who sympathize with Watanabe, who is such a natural person, and I'm sure there will be more and more haters in the future.

　As the subtitle of this blog says, `` Do not pursue those who leave, nor reject those who come .'' I'm not a real-life manager, so I can only date people I like online. I've been talking about Watanabe's grudges so far, but both his blog and Twitter are doing well. Well, it might be the best time ever.

　Real management jobs are tough. This is because you have to get along well with people you are not good at . Watanabe also wants to become an attractive person with good communication skills so that people will like him more. However, people don't act modest online. I would like to develop Watanabe's world as he pleases.

　This is a big departure from the topic of middle management, but in the sense that I also manage blogs, I should also be considered a blog manager . Through my blog, I intend to communicate with my readers and report information that will benefit them, who are my boss and company president.

　In summary, Watanabe is not suitable for real management positions. This is because I am better at increasing numbers by making creative efforts on-site. However, the more you raise the number, the closer you get to a managerial position that you are not good at, which is nothing but a dilemma.

　So, as I had previously declared, I came to the conclusion that I would study business administration and marketing. `` Watanabe, now to the president '' After all, there are many kinds of human relationships. Morale may drop in relationships. However, if you keep getting caught up in such things, you will only slow down your growth. You don't have to deal with it.

　I'm sorry that I couldn't write a silly article like I usually do this time. I never even meet the readers who came to this blog expecting such articles. Starting tomorrow, I will change my mind and make amends.

　That's why it's time for Hotaru no Hikari in this article. Some of our readers may be in management positions, but there is no need to seriously worry about interpersonal relationships. Watanabe, who is always worried, has no persuasive power to say this, but I'm sure there will be readers on his side.

　20% are allies, 60% are not interested, and 20% are enemies . Watanabe is one of the 20% of readers. And I believe that the readers are also one of Watanabe's 20% allies. I hope we can enjoy each other's lives in the coming days. See you soon.

First order congruence and Fermat's little theorem, Part 2! What are the conditions for Fermat's little theorem to hold? dragon blog

 Hello. This is Tenmei Watanabe from Dragon Blog. Last time, I explained keywords for dragon games. According to this, he explained the linear congruence formula a ≡ b (mod m), where a and b are congruent by modul m, and a – b = my. In other words, we can say that a and b have the same remainder when divided by m.

https://nabenekocom.blogspot.com/2024/02/i-will-explain-primary-congruence.html

Here, I would like to add one more explanation: my represents a multiple of m, and if m=18, it will be the number 18y. The reason why I used y here is that you can basically use any variable you like as long as there are no symbols that mean the same alphabet in the formula leading up to it. For example, to put it in an extreme way, if you set 18y to 18:00 and y=hours, there is no problem as long as it is not inconvenient for you or the person being viewed.

Now, regarding Fermat's little theorem, first let's remember how to express axaxa=a^3. A is repeated three times. Fermat's little theorem means that a^(p – 1) ≡ 1 (mod p). The expression is a little difficult, so let's actually substitute numerical values. Let p=7 be a prime number. Substituting p=7 into the formula of Fermat's little theorem, we get a^(7-1) = a^6 ≡ 1 mod 7. a^6 means multiplying a six times.

As a review before this, mod 7 calculates the remainder when divided by 7, with 7 as one period. In other words, a=0,1,2,3,4,5,6 are raised as candidates, and a=7 has a remainder of 0 when divided by 7, so 7 ≡ 0 mod 7, which overlaps with a=0, so it is excluded. Masu. Negative values ​​can also be converted to a value in the same way.

1 ^ (7 – 1) ≡ 1 ^ 6 ≡ 1 mod 7
2 ^ (7 – 1) ≡ 2 ^ 6 ≡ 64 ≡ 1 mod 7
3 ^ (7 – 1) ≡ 3 ^ 6 ≡ 729 ≡ 1 mod 7
4 ^ (7 – 1) ≡ 4 ^ 6 ≡ 4096 ≡ 1 mod 7
5 ^ (7 – 1) ≡ 5 ^ 6 ≡ 15625 ≡ 1 mod 7 6
^ (7 – 1) ≡ 6 ^ 6 ≡ 46656 ≡ 1 mod 7

One thing to note here is that a=0 is 0 no matter how many times it is multiplied by 0, so 0^(7-1)=0. Multiplying by 0 six times is still 0. In other words, if mod 7 is used, even if the number one less than that (7-1)=6 is used as an exponent, it will be 1 except for a=0.

Here, I would like to use a calculator to calculate the remainder of 109÷8. First, substitute "109", "÷", "8", and "=". "13.625" will be displayed on the calculator screen. Now subtract an integer greater than the decimal point, in this case 13. "ー" "13" "=". The screen will display "0.625", so multiply the original divided value by 8. When you press "x", "8", and "=", the desired value "5" will be displayed on the screen. This 5 is the remainder of 109÷8. When we check the calculation, we find that the calculation was correct as (109-5)÷8=13 with a remainder of 0.

Next, just to be sure, let's check whether this Fermat's little theorem is correct. The next value will be mod9.

0 ^ 8 ≡ 0 mod 9
1 ^ 8 ≡ 1 mod 9
2 ^ 8 ≡ 4 mod 9 
3 ^ 8 ≡ 0 mod 9 
4 ^ 8 ≡ 7 mod 9 
5 ^ 8 ≡ 7 mod 9
6 ^ 8 ≡ 0 mod 9
7 ^ 8 ≡ 5 mod 9
8 ^ 8 ≡ 1 mod 9

The results of mod9 were disastrous, but in mod7, 7 was a prime number. In this case, 9 is 3×3, so it is a composite number and not a prime number. Here, mod9 has two 1s, why? First, let's check whether 9 is relatively prime. Relative prime means that the greatest common divisor is 1. In the previous Dragon Game explanation, the greatest common divisor was the overlapping part of 16=2x2x2x2 and 24=3x2x2x2. In other words, 24 and 16 have 2x2x2 in common, so the greatest common divisor is 2x2x2=8.

If I write this far and explain the combination of the linear congruence and Fermat's little theorem, it will probably become quite a long article, so I would like to touch on the relationship between disjoint and 9 that I just explained and leave it for the next article. I think. I'm probably a bit inexperienced since I've just started using Dragon Games, but I'll write one article for each keyword, and one article for the summary. Since we will be mixing two keywords this time, I think the number of articles should be 2+1. Well, let's continue.

Let's check whether the values ​​up to 9 are prime with 9 in order.

The greatest common divisor of 9 and 1 is 3 x 3 and 1, so it becomes 1. First, the first greatest common divisor is 1, which is a relatively prime value. 9 and 2 are 3×3 and 2, so they are prime to each other. In other words, the second greatest common divisor is 1. Since 9 and 3 are 3×3 and 3, the greatest common divisor is 3 and they are not relatively prime. 4 and 5 are mutually prime★★. Since 6 is 2×3, the greatest common divisor is 3, so they are not coprime. 7 and 8 are mutually prime★★.

Therefore, the six elements that are relatively prime are 1, 2, 4, 5, 7, and 8. Here, the six numbers that are coprime to 9 are expressed as φ (pronunciation: phi) and are called Euler's phi function.

φ(9)=6.

mod7, which uses the prime number 7, is coprime other than 0, so there are 6 values ​​where the greatest common divisor is 1. A prime number is expressed as φ(p) = p – 1.

φ(7) = 7 -1 = 6

Returning to the topic, the composite number 9, which is the product of an integer and an integer, is a ^ φ(m) ≡1 mod m, and although a and m must be relatively prime, a ^ φ(9) = a^6 =1 mod 9. 

Taking 4 and 5, which were not 1, as an example, it becomes as follows.

4 ^ 6 ≡ 4096 ≡ 1 mod 9
5 ^ 6 ≡ 15625 ≡ 1 mod 9
6 ^ 6 ≡ 46656 ≡ 0 mod 9
7 ^ 6 ≡ 117649 ≡ 1 mod 9

Here, 6= 0 mod 9 because 6 and 9 are not relatively prime.

The number theory textbook I'm reading includes an explanation of Fermat's little theorem. If you want to know more, please read ``Number Theory for Beginners'' by Joseph H. Silverman.

Next time, I will synthesize the linear congruence and Fermat's little theorem, so please look forward to it. I spent a day researching a combination of these two keywords, but something happened. stay tuned. thank you for reading. See you soon.
