[3] FUNsys Project

Information on the campus is managed separately from Hope, Manaba, Student and each platform. As a current situation, there were many opinions that students wanted to consolidate the reference places in one place. Therefore, our project aimed at unified management of information and construction of a system that is truly easy to use for students. As an approach, as the first step of this fiscal year, we have made WebAPI information on campus using scraping technology.

学内の情報は，Hope，Manaba，Studentと各プラットフォームで別々の情報が管理されています．現状として，学生からは参照する場所を一箇所にまとめて欲しいという意見が多くありました．そこで，我々のプロジェクトは，情報を一元管理し学生にとって，本当に利用しやすいシステムの構築を目的としました．アプローチとしては，今年度第一段階として，学内の情報をスクレイピングの技術を用いて，WebAPI化しました．

[1] Swimming Club in Middle School

I was a director. The members of the club activities were such that there were many excellent players and some athletes participating in the national competition. Among them, why was I chosen as the director? In addition, I spent a year spent feeling a lot of oppression, such as not being able to show unless I got a result in front of an excellent member. Throughout the year, I was sorry that I could think only about myself rather than director, neglecting to consider the club activities as a whole.

部長を勤めていました．部活のメンバーは，優秀な選手が多く全国大会に出場する選手もいるほどでした．その中で，なぜ自分が部長に選ばれたのか．更には，優秀なメンバーの前に立つ自分が結果を出さなければ示しがつかないなど多くの圧迫を感じながら，過ごした1年間でした．1年を通して，部長というよりは，自分のことしか考えられず，部活全体を考えるという事を怠ってしまったという反省がありました．

[2] Swimming Club in High School

I was deputy manager. As a role, the director was absent, so I was in charge of almost all roles. Club activities, unlike the club team, are experienced athletes. Therefore, many differences in ability will occur in the team as well. Among them, having organized teams and made menus based on personal skills and the events I wanted to do. And I think that through the measures such as what kind of atmosphere it makes members can do their best, I think that they have cultivated their eyes to see individuals in a bird's-eye view. Also, as a different point from the junior high school days, I was able to pursue better club activities while sharing my work with my members instead of trying to do all the work alone.

副部長を勤めていました．役割としては，部長は不在であった為、ほぼ全ての役割を担当していました．部活動は，クラブチームとは異なり，経験が浅い選手もいます．そのため，チーム内でも実力差が多く生じてきます．その中で，個人の実力とやりたい種目を元に，チーム編成とメニュー作りを行ったこと．そして，どのような雰囲気を作っていけば，メンバーは頑張っていけるかなどの施策を通し，俯瞰的に個人を見る目を養えたと思います．また，中学生時代と異なる点として，単身で仕事全てをこなそうとするのではなく，メンバーと共に，仕事を分担しつつより良い部活を追い求めることができました．

[4] Private Cloud for Campus Education

Various lectures and activities are carried out at our university, but in many cases each student sets up the necessary software etc. on their own PC. Therefore, different environments are constructed for each PC little by little, which may lead to unexpected troubles at the time of execution, causing inconvenience to exercises as well. In order to solve such problems, this team constructs and operates a private cloud infrastructure for the needs such as exercises and self-study within the university, and provides it to lectures and students. In addition, we will actively utilize surplus computing resources of PCs installed in the classroom and proceed with research and verification for use on the foundation.

本学では様々な講義や活動が行われているが、それに必要なソフトウェアなどは各学生が自分のPC上にセットアップを行っているケースが多い。そのため、PC毎に少しずつ異なる環境が構築され、実行時に予期せぬトラブルを招くことがあり、演習課題にも不都合が生じる。このチームでは、そのような問題を解決するべく、学内の演習・自習などのニーズに向けたプライベートクラウド基盤を構築・運用し、講義や学生に対して提供する。また、教室設置PCの余剰計算資源の活用に積極的に取り組み、基盤上での利用に向けた調査・検証を進める。
