  • Interfaculty Comparison of Generation Z's willingness to contribute to society based on WTP of SDGs

    Generation Z (born between late 1990s and early 2010s) is considered to be more motivated to contribute to society and more enthusiastic about solving social issues such as the SDGs (Sustainable Development Goals) than other generations before them. We conducted a survey on willingness to contribute to society by asking regional university students to select their WTP (willingness-to-pay) for the importance they attach to specific items of the SDGs. This study examines the factors that influence the level of willingness to contribute to society by comparing the results of the survey across faculties.

    Generation Z (born after the mid-1990s) is considered to be more motivated to contribute to society and more enthusiastic about solving social issues such as the SDGs (Sustainable Development Goals) than other generations before them. Many of these surveys are in the form of questions asking whether or not or which specific items are important. In this study, based on the results of a survey conducted on student at a regional university in the form of questions asking WTP (Willingness To Pay) of specific items of SDGs, we will examine Generation Z's willingness to contribute to society.

    The Online Attention Game (OAG), which has been developed by the authors, is a gaming simulation that allows players to experience simulated online attention competitions through posting headlines of online news or articles, which are created by the players or selected from among headlines found by internet, and evaluating those posted headlines. The game is intended to increase players' awareness of their digital identity development, and to enable to analyse individual players' online posting behaviour under the situation of online attention competition. In this study, we conduct the OAG, which was played in a classroom setting, in a remote environment, and discuss the results of it to investigate the nature of online posting behaviour and the effectiveness of the game for digital identity education.

  • The Online Attention Game for Digital Identity Education: An Exploratory Study.

    Ill-considered postings by young social media users hungry for attention have recently garnered headlines. Imprudent online posts distort the posters' digital identity, which refers to one's online image as perceived by others. Online attention-seeking behaviour may result in digital identities that are separate from a person's true nature, which can lead to social and mental harm. To mitigate these impacts, effective educational material is needed to help non-technical users understand the risks and consequences of thoughtless, attention-seeking online behaviour. This study takes the first step towards fulfilling this educational need by developing the Online Attention Game (OAG), which is played in a laboratory or classroom setting (OAG-CS) or remotely (OAG-R). It replicates the online competition involved in seeking other social media users' attention. Through five OAG games (two OAG-CS games with students, two OAG-CS games with researchers, and one OAG-R game with researchers), we confirmed the tendencies and characteristics of young university students' and adult researchers' online posting behaviour. Through carrying out the OAG-R successfully, we ensured the OAG was useful for digital identity education even at the difficult time of the COVID-19 pandemic.

    Ill-considered postings by young social media users hungry for attention have recently garnered headlines. Imprudent online postings may distort posters' digital identity, which is someone's online image as perceived by others. Online attention-seeking behaviour may result in digital identities that are divorced from a person's true nature, which can lead to social and mental harm. To mitigate these harms, effective educational material is needed to help non-technical young users understand the risks and consequences of thoughtless, attention-seeking online behaviour. Because such materials do not exist, we took the first step towards fulfilling this educational need by developing the Online Attention Game (OAG). The OAG is an online game played in a laboratory or classroom setting that replicates the online competition involved in seeking other social media users' attention. Through four OAG games (two with students and two with researchers), we confirmed the differences in posting and evaluation behaviour between young university students and adult researchers.

    We present session management architecture on e-mail-based learning support environment. This system consists of attendance management subsystem, short examination management subsystem, questionnaire subsystem, and so on. Both students and teachers mainly use only e-mail functions and it can access the server. Management of lecture sequence is important for continuous and habitual study. Therefore we need a sequence management function using e-mail communication, and so we introduce session-based communication architecture. In this paper, the outline of this system is described, and the functions and effects are discussed.

    Since 2004 we had researched education-support system as industry-university research and development collaboration for about five years. Moreover we arranged a industry-university collaboration environment, and then incorporated a university-originated venture company. This paper will describe the actual application of a mobile system developed by a venture company incorporated by a university with industrial collaboration. In addition we analyze similar systems developed by university, industry, and industry-university collaboration, and discuss validity of industry-university research and development collaboration, and success factor for practical use. We explain the essence of industry-university collaboration program by the concept of "Ba".

    In recent years, many local governments in Japan have outsourced the operation of public sewage treatment plant to the private sector. Under this public-private relationship, we need to consider the principal-agent problems and transaction costs. That is, for control activities by the principal and signaling activities by the agent, information technology can be useful for us. In addition, from the viewpoint of transaction costs, we have pointed out the need for standardization of equipment and software.

    本研究では、労働安全対策活動のコストをより適切に把握することおよび、その費用対効果の適切な把握方法を検討した。
    日本でも労働安全対策の国際的規格のひとつであるOHSASに適合した企業が増加している。また、企業の社会的責任として労働安全対策活動に取り組む企業が増えている。これら先進的企業に訪問調査をすることにより、明示的・積極的に労働安全対策を実施する企業の情報を収集する一方、安全規格に適合的な作業服を製造・販売しようとする愛媛県内の企業と情報交換を行い、より詳細な専門知識の提供を受けながら研究を進めた。また、RFIDタグを利用した施設管理の効率化について実地調査を行う機会を得たため、これを労働安全対策活動の効率化と関連付けて検討した。
    すなわち、労働安全対策活動のコストについては、活動基準原価計算のように、特に制度としての原価計算の集計範囲を超えた、直接的に製造に関わらないコストを幅広く捕らえた把握が、経営管理の上で必要であることを明らかにした。
    また、その費用対効果の適切な把握については、品質原価計算を援用する手法を提案した。具体的には、「予防コスト」「評価コスト」「失敗コスト」というPAF分類を労働安全の問題に応用し、援用できる部分と応用できない部分とを明るみにした。
    さらに、近年、民間企業における派遣労働、また地方自治体経営における民間委託のように、従来からある組織内部...
