Examination of Fraud Prevention Possibility by Online Authentication Using Fingerprint Recognition System Named JAMS (Josai Attendance Management System)
Get PDF2020 年のコロナ禍により，感染対策の面から社会のデジタル化・オンライン化が急速に進んでいる。文部科学省は，GIGA スクール構想として，2023 年度までに義務教育の全課程において児童生徒のひとりひとりに学習用端末を購入することを決定した。これは，高速大容量の通信ネットワークの環境の新しいスクールの実現を推進したものである（1）。また，大学入試などにおいても文部科学省の「令和4 年度大学入学者選抜実施要項」（2021 年6 月4 日）で，新型コロナウイルス感染症拡大防止の観点から，ICT を活用したオンラインによる入学試験への工夫が要請されている。以上のことから，城西大学の杉本理，栗田るみ子，志田崇の研究チームはデジタル化・オンライン化へ向けた学習環境の構築のための，研究設備整備費等補助金を獲得した（2）。補助金により，学内にサーバーを設置し，世界初のアカデミア所有のFIDO 2 認証サーバーを完成させた。「FIDO 2（Fast Identity Online 2）標準を利用したパスワード認証環境による機密性，可能性の高いデジタルクラスルームの運用システムを構築し，JAMS（Josai Attendance Management System）」と名付けた。本論では，JAMS の活用による，オンライン上での，「なりすまし」による不正防止の可能性に関する検討について述べる。Due to the corona epidemic in 2020, the digitization and onlineization of society has been rapidly progressing from the aspect of infection control. The Ministry of Education, Culture, Sports, Science and Technology has decided to purchase learning terminals for each child and student in all courses of compulsory education by 2023 as the ‘Global and Innovation Gateway for All’. This aims to promote the realization of a new style school with an environment for high-speed, large-capacity communication networks.In addition, as indicated by the Ministry of Education, Culture, Sports, Science and Technology’s “Guidelines of the Selection of University Admissions for the 4th year of Reiwa (announced on June 4, 2021), universities are required to utilize ICT for their entrance examination, from the perspective of preventing the spread of new coronavirus infections.Under such circumstances, the research teams of Osamu Sugimoto, Rumiko Kurita, and Takeshi Shida of Josai University planned a project to build a learning environment for digitization and onlineization, and obtained the subsidies for research equipment maintenance costs, etc. Using this subsidy, a server was set up on campus, and complete the world’s first academia-owned FIDO 2 (Fast Identity Online 2) authentication server.The research team has built an operation system for digital class rooms with high possibility of confidentiality by password authentication environment using FIDO 2 (Fast Identity Online 2) standard, and named it JAMS (Josai Attendance Management System). This paper describes the examination of possibility preventing fraud caused by spoof on online, with utilizing JAMS.論

Enhancement of Skin Permeation of a Hydrophilic Drug from Acryl-Based Pressure-Sensitive Adhesive Tape
Get PDFPurpose: Penetration enhancers are necessary to overcome a formidable barrier function of the stratum corneum in the development of topical formulations. Recently, non-lamella liquid crystal (NLLC)-forming lipids such as glycerol monooleate and phytantriol (PHY) are gaining increasing attention as a novel skin permeation enhancer. In the present study, fluorescein sodium (FL-Na) was used as a model hydrophilic drug, and acryl-base pressure-sensitive adhesive (PSA) tape containing NLLC forming lipids, mono-O-(5,9,13-trimethyl-4-tetradecenyl) glycerol ester (MGE) or PHY, was prepared to enhance drug permeation through the skin.Methods: A PSA patch containing FL-Na was prepared by mixing FL-Na entrapped in NLLC and acrylic polymer. FL permeation through excised hairless rat skin, and also human skin, was investigated. Changes in lipid structure, folding/unfolding state of keratin in the stratum corneum, and penetration of MGE into the stratum corneum were investigated using confocal Raman microscopy.Results: Enhanced FL permeation was observed by the application of a PSA patch containing MGE and PHY. Especially, dramatically enhancement effect was confirmed by 15% of MGE contained formulation. Penetration of MGE provided diminished orthorhombic crystal structure and a peak shift of the aliphatic CH3 vibration of keratin chains toward lower wavenumbers.Conclusion: The present results suggested that the formulation development by adding MGE may be useful for improving the skin permeation of mal-permeable drugs such as hydrophilic drugs
The Trial of Face-to-Face and Online Hybrid Lecture on Large-group Class
Get PDF本稿は筆者が 2020年7月に試行したハイブリット型式の授業について報告するものである。新型コロナウィルス感染症が拡大する中で，城西大学では 2020年度前期の対面授業は中止されたが，後期授業に備える意味を込めて実施した。その結果，教室環境の整備や，使用する機器の準備等，安全な講義運営のための重要な知見を多数得ることが出来た。特に座学の一斉型講義においても，対面授業を必要とする学生が存在することが明らかになったのは大きな成果と言えるだろう。This paper reports on the trial of the hybrid-style lecture that the author gave in July 2020. As the spread of COVID-19, the face-to-face class at Josai University was canceled in the first term of 2020, but I tried this trial lecture with the intention of preparing for the second term. Through this trial, we were able to obtain a lot of important knowledge for safe lecture management, such as improving the classroom environment and preparing the tools to be used. And I think it is especially important that there are students who need face-to-face style even in the classroom lectures.教育実践研究 / Educational Practice Researc
How well do College Students Understand Basic Knowledge? A Study Based on the Short Quizzes in Freshman Class
Get PDF本稿は，城西大学経営学部の初年次授業で行った数学と社会の基礎知識テストを分析することにより，大学生の基礎学力を考察したものである。8年間のテスト結果を分析した結果，以下の点が明らかになった。(1)設問の正答率が半分以下の学生は，数学で 24.1％，社会で 19.6％を占める。(2)数学では中央値と複利計算，社会では高度経済成長期，配当，通貨についての正答率が低く，普段の学習や日常生活で使用頻度が低いテーマを正しく理解できていない学生が多い。(3)また，2回目の再テストでは正答率が大幅に向上しており，知識がないというより解法を忘れている学生が多いと推定できる。以上の点から，学部のリメディアル教育においては一度忘れてしまった基礎知識を回復させる教育内容が重要である点など，運営の改善につながる可能性が見いだされる。This paper considers the basic academic ability of university students by analyzing the basic knowledge test of mathematics and social studies, conducted in the freshman class of the Faculty of Business Administration of Josai University. As a result of analyzing the test results for 8 years, the following points became clear.（1）Students with less than half the correct answer rate of questions account for 24.1％ in mathematics and 19.6％ in social studies.（2）The percentage of correct answers is low for "median and compound interest calculations "of mathematics and "Japanese high economic growth period, dividends, foreign currency "of social studies. These students may not understand themes that are rarely used in daily learning and life.（3）In the second retest, the percentage of correct answers has improved significantly, and it could be interpreted that the student has forgotten how to solve the problem rather than lack of basic knowledge.（4）It is found that there is a possibility that the remedial education, which is operated by compensating for the lack of basic knowledge and focusing on the review of "regaining the forgotten knowledge ", will lead to the improvement of educational management.教育実践研究 / Educational Practice Researc
Determinants of Individuals’ Acceptance of Cashless Payment Methods in Japan
Get PDFキャッシュレス決済が経済・社会的側面からだけでなく，コロナ禍において衛生面からも注目を浴びている。これまでキャッシュレス決済を促すような金銭的インセンティブを与える仕組みを社会に導入し，成功を収めているものの，持続的な促進を考えるのであれば，非金銭的インセンティブによる仕組みについても考えていく必要がある。本研究では，この非金銭的インセンティブの可能性について検証する。具体的には，キャッシュレス決済サービス（クレジットカード決済サービス，交通系 IC カード決済サービス，QR コード決済サービス）に注目し，これらのサービスに関してオリジナルの技術受容モデル（TAM）に「知覚された不安」「知覚されたリスク」「社会的影響」「信頼」という新たな要因を組み込んだモデリングおよびそのモデルの検証を行った。その結果，これらの決済サービスの間で利用意図につながる要因ならびに心理的構造が異なることなどを明らかにした。Recently, attention on cashless payment methods are attracted not only from the economic and social aspects, but also from the aspect of good hygiene. Japanese government implements the policy to give monetary incentives that we promote to use the cashless payment methods. In addition, for the purpose of rapid and sustained spread of cashless payment, we also must discuss the non-monetary incentives for it. In this article, we verify the non-monetary incentives for using the cashless payment methods employing credit card, IC cards, and QR-code. Particularly, we build and test our technology acceptance model (TAM) for cashless payment methods that incorporated into “perceived anxiousness,” “perceived risk,” “social influence,” and “trust.” As a result, we found that it was different to some determinants of individuals’ acceptance of each cashless payment method. From this viewpoint, we could confirm that psychological structures were different among three cashless payment methods.論文 / Treatise
