Japanese intellectual property from university students' IDs (Wedge) --Yahoo! News

　JCAST News reported on February 15 on February 15 that "Waseda -University, about 100 people failed by simultaneous viewing of online classes," the Faculty of Ripples Commercial Faculty of Commerce, "The Faculty of Faculty of Ripples is a fact and recognition." It is. It is a method of regenerating on -demand classes simultaneously on multiple tabs and multiple PCs, which are called "double windows" among students. Many students can get credits in a short time, but at Waseda University, "double windows" are not treated as attending, and the results are not satisfied because the requirements are not satisfied. It is a certified F rank. Waseda University's internet classes use a free open source learning platform called "Moodle". The problem is that the learning platform has no function to prohibit simultaneous regeneration. There are quite a few systems that do not have "exclusive control" because it is necessary to create a mechanism called "exclusive control" with the same account that can execute as many as the same account. Web mail is a good example.

"Double window" leaks Japanese intellectual property

　The problem of "exclusive control" is not only "double window" but also Japanese intellectual property leaked overseas. In the first place, in Japanese universities, the management of the ID given to students is left to each university. The ID assigned at the same time as enrollment should be invalidated at the same time as graduation, but most universities can be used after graduation. In recent years, more and more universities have left the alumni association to traders, but in most cases, the IDs given during school days are used for the alumni association member ID, so some IDs that are not invalidated forever. It seems to be increasing. On the other hand, the ID given to students is also used to access academic networks (sinet). SINET is the academic information base used by universities and research institutions throughout Japan, which are built and operated by the National Institute of Informatics (NII). By connecting to an academic network, large experimental facilities, supercomputers, observation equipment, academic information databases, etc. can be used, and it is possible to cooperate with overseas. In particular, papers included in the academic information database are popular because they are originally paid but can be used for free. Therefore, it can be said that the ID of Japanese university students is very useful. It is not a student who knows the true value, but is not a student who aims to acquire credits using a "double window". In particular, Chinese students who are sending a large number of students to Japanese universities are extreme.
