If the application is approved, you can obtain a period of stay for 6 months. Extension is admitted only once. Therefore, it is possible to stay in Japan for job search for up to 1 year after the graduation.

    5. Fee: 4,000 yen
      *The immigration office may require other additional documents for the application.
  • When you need to change your status of residence due to becoming employed after graduation
    You need to confirm a type of status of residence after becoming employed. Also, you need to prepare the appropriate type of application form and other necessary documents, and then apply to the immigration office. The immigration office usually starts accepting the application from December for the students who are going to be employed from April after your graduation in March. However your status will be changed after your graduation. In the application form, there is an Organization part. You need to ask the company to which you are being employed, to fill out this part of the application.
  • When you want to change your status of residence from "Temporary Visitor" to others
    When you would like to change your status of residence from "Temporary Visitor" to another type of status of residence, it is not usually approved unless you have a particular reason.
    Therefore, in this case, you need to apply for the certificate of eligibility for status of residence (CESR) first, and then you can apply for changing of status of residence after your CESR has been issued. However, if your CESR is not issued by the current expiration date as a temporary visitor, you need to leave Japan before the expiration date. Once you return to your country, you need to apply for your visa after you receive your CESR. After you obtain the certain type of Japanese visa, you can enter Japan again.

Theorem vs Lemma vs Corollary vs...

Definition — a precise and unambiguous description of the meaning of a mathematical term. It characterizes the meaning of a word by giving all the properties and only those properties that must be true.

Theorem — a mathematical statement that is proved using rigorous mathematical reasoning. In a mathematical paper, the term theorem is often reserved for the most important results.

Lemma — a minor result whose sole purpose is to help in proving a theorem. It is a stepping stone on the path to proving a theorem. Very occasionally lemmas can take on a life of their own (Zorn’s lemma, Urysohn’s lemma, Burnside’s lemma, Sperner’s lemma).

Corollary — a result in which the (usually short) proof relies heavily on a given theorem (we often say that “this is a corollary of Theorem A”). Proposition — a proved and often interesting result, but generally less important than a theorem.

 Conjecture — a statement that is unproved, but is believed to be true (Collatz conjecture, Goldbach conjecture, twin prime conjecture).

Claim — an assertion that is then proved. It is often used like an informal lemma. Axiom/Postulate — a statement that is assumed to be true without proof. These are the basic building blocks from which all theorems are proved (Euclid’s five postulates, Zermelo-Fraenkel axioms, Peano axioms). Identity — a mathematical expression giving the equality of two (often variable) quantities (trigonometric identities, Euler’s identity).

Paradox — a statement that can be shown, using a given set of axioms and definitions, to be both true and false. Paradoxes are often used to show the inconsistencies in a flawed theory (Russell’s paradox). The term paradox is often used informally to describe a surprising or counterintuitive result that follows from a

[InterstingTopic] Người Nhật không còn siêng năng như 10 năm trở về trước

From:  http://www.japantoday.com/category/lifestyle/view/despite-hardworking-image-are-japanese-just-as-lazy-as-the-rest-of-us

Despite hardworking image, are Japanese just as lazy as the rest of us?

TOKYO —
Workers in Japan are often perceived by the rest of the world as possessing an extremely strong work ethic, which drives them to daily acts of unpaid overtime, selfless sacrifice of rightfully accrued holiday time, and occasionally even to karoshi, or death by overwork. So pervasive is this perception that the image of the exhausted salaryman splayed out across train carriage floors after a hard day’s work has become a sort of unofficial symbol of Japanese working life.
But what people who have actually worked in Japanese offices will tell you is that, while simply existing in the strict hierarchical system of a Japanese workplace can be an exhausting feat in and of itself, it doesn’t necessarily mean that everybody’s getting loads of work done. In fact, Japanese workers may be just as lazy as the rest of us. So how come everybody still thinks they work so hard?
To try to break down the reasons why Japanese people aren’t actually doing as much work as we in the west think they do, we’re going to talk about three misconceptions about Japanese working life, and the ways in which they are kinda false.
Misconception 1: Japanese workers never take holidays; therefore they must work hard
It’s common in Japan to only get around 10 days paid holiday a year to begin with, but most of those paid holidays end up going unused, not because people are denied when they try to take them (they’ve earned ‘em, after all) but because in general nobody ever even asks to take them.
Why it’s false:
The perception is that Japanese workers voluntarily give up paid vacation days because they would much prefer to work. Not only is this not true, it gives too much credit to workers’ dedication and fails to address the real reason why nobody wants to take paid holiday – peer pressure.
Taking paid holiday means leaving coworkers to pick up your slack, which is a total no-no in Japan’s group-oriented society. Also, since getting ahead at a company in Japan relies so much on how you behave, nobody wants to look like a slacker who would rather be sipping beers on a couch somewhere than hard at work. There’s also the fact that asking to take paid holiday usually means directly petitioning your supervisor, who only has to raise an eyebrow to let you know in no uncertain terms that they consider your request to be the ultimate in bare-faced cheek.
Also, Japan actually has a hefty amount of public holidays. There’s a week at the end of the year, Golden Week, Obon, and numerous stand-alone national holidays which pop up practically every month. With another tantalising national holiday always just around the corner, it’s easier to just hang on until then rather than specifically ask for paid holiday. Basically, while it’s true that people aren’t taking their paid holidays the way they probably ought to be able to do, it’s not necessarily because they’d rather be at work or don’t wish they could use them.
Misconception 2: Japanese workers do loads of overtime; therefore they must work hard
“I would never want to work in Japan, because Japanese office workers don’t get home until midnight!” is something I hear a lot from friends back home. Certainly the Japanese seem to be doing quite a bit of overtime, and the last train is usually stuffed full of near-comatose salarymen and office ladies.
Why it’s false:
Working more hours doesn’t necessarily mean working harder, especially in Japan where it’s a common sight to see people stretching out small tasks and generally faffing around in order to try to spread the normal amount of work they have across a full day and into the overtime hours. This can be attributed to two factors: peer pressure again, and, secondly, wanting more money.
Companies that offer paid overtime usually find that their employees take them up on it, every single day. After all, that’s extra money you could be bringing home in today’s tough economy, and since nobody seems to actually care if you’re working or not as long as you’re on the clock, then why not spend the evening goofing around at your desk and making bank for it? Unpaid overtime is a whole different kettle of fish, and is usually undertaken for simple reasons such as “everybody else is doing it” and “I couldn’t possibly go home before the boss without bringing shame upon my entire family and getting daggers from my workmates.”
While the Japanese might well be spending more time at work than people in other countries, it’s not necessarily true that they’re being more productive. With the average day including endless, pointless meetings, verging on voluntary bureaucracy, filing of entirely unnecessary paperwork, and sneaking naps at your desk, it’s amazing that some people in Japan get any work done at all.
Misconception 3: Japanese workers are exhausted all the time, therefore they must work hard
Those poor salarymen slumped on street corners, so exhausted they’ve somehow lost control over their own bodies and on occasion a few articles of clothing too. That poor office lady snoring and drooling on everyone’s shoulders on the last train of the night. They must just be run ragged at work.
Why it’s false:
As we mentioned above, it’s pretty common for workers in Japan to try to conserve energy during the day by not getting especially stuck into their work. Then, in the evening, it’s all nomikai, or drinking parties, and schmoozing, a vital part of staying part of the work group and getting to know the right people in order to further one’s career and be looked upon favourably by the boss.
Maybe those people on the train aren’t tired out from working – maybe they’re tired from compulsory socializing. That’s not to mention the huge quantities of booze that are required to lubricate these post-work social engagements. Conbini shelves are stuffed full of supplement drinks in order to keep exhausted post-work partiers going longer, and to help alleviate the inevitable hangover symptoms. We can’t deny that long days full of work-stretching and drinking with the higher-ups isn’t exhausting, but does it result in hard work and getting things done?
With evidence now suggesting that it’s actually the Americans who are working the hardest in the world (as reported last year by ABC News), is it perhaps time for the myth of the hyper-diligent Japanese worker to be debunked, once and for all?
