    In large-scale system development, telework and communication in remote environments are not uncommon. Smooth communication is crucial in team building. In this study, we approach communication issues in large-scale development using the idea of gamification. Specifically, we conducted a workshop using a gesture game and a virtual scavenger hunt as part of a team-building activity, we confirmed that the game has a certain effectiveness in addressing communication issues in large-scale development. In the gesture game, there is room for improvement in the content of the questions. In the future, we would like to improve the game content and contribute to solving communication issues in remote environments.

    In recent years, ERP systems have become obsolete, and many are being replaced with new systems or upgraded to the latest versions. Replacements are often migrated without changing the business specifications, hoping to keep the current status without any specific requirements from the users. As previous studies have shown, in such cases, it is difficult to accurately grasp the requirements, and requirement omissions occur. This study examines, based on a case study, how to investigate the current system under such circumstances to ensure a successful system implementation. It is hoped that this study will help those in charge of system implementation who are struggling with the current as-is requirements.

    This paper discusses future issues and countermeasures for the spread of contactless credit card transactions, which has been an issue in previous studies toward secure transactions in stores under COVID-19. The authors analyzed the situation before and after COVID-19 through a literature survey and text mining of newspaper articles. As a result, it became clear that “credit card contactless transactions” were in the “introduction” phase before COVID-19, but are shifting to the “use” phase after COVID-19. The challenges to the diffusion of credit card contactless transactions identified in this analysis and in previous studies are clearly stated as increasing awareness, providing gainful use, diffusion to the elderly, introduction in rural areas, and involvement of universities and research institutions, and countermeasures to these challenges are discussed. As a solution to these issues, the report suggests that the expansion of the introduction of contactless credit card transactions on public transportation will provide an opportunity.

    This study delves into the realm of management accounting changes, specifically within the context of institutional complexity, as discussed through the lens of institutional theory. The principal aim is to elucidate the mechanisms that underlie institutional complexity in the context of management accounting changes by providing a comprehensive overview and comparative analysis of two prominent analytical models. These models, proposed by Smets et al. (2012) and ter Bogt and Scapens (2019), respectively, delineate the processes of institutionalization within organizations grappling with institutional complexity. The research encompasses a thorough review of each analytical model, the systematic categorization of their distinctive attributes, and a rigorous comparative analysis of their variations. Consequently, the findings reveal notable differences in the processes of institutional change within each analytical model, whether they manifest as trickle-up or trickle-down patterns. Additionally, the findings underscore a discernible distinction between models that presuppose the resolution of institutional complexity and those that do not.

    This paper proposes the concept of an enterprise system with a knowledge base and agent. Knowledge base is commonly used in expert systems, which is a part of AI, Artificial Intelligence. The architecture of enterprise systems is usually monolithic. The author proposes an agent-based system to segregate the knowledge and database access from the algorithms of the enterprise system. The concept allows the architecture to be a more distributed and independent system and more events driven.

    This paper discusses the proliferation of online classes due to the COVID-19 pandemic and the utilization of the metaverse in education. Online classes come in various forms, and the metaverse has gained attention as part of this trend.The year 2022 is referred to as the “metaverse year,” with significant societal focus in education and business sectors. The metaverse is anticipated to complement the drawbacks of online classes. Previous cases suggest its effectiveness in ProjectBased Learning (PBL) environments. However, challenges like proficiency in IT device operation and issues like VR-induced discomfort are noted. Successful use of the metaverse in pre-enrollment seminars has demonstrated heightened student interest and motivation. Future efforts should concentrate on improving IT support and resolving connectivity issues, while also exploring methods for providing more realistic learning experiences.

    The automotive industry is working to achieve net zero carbon dioxide emissions by 2050. Scientific studies have shown that recycling of materials is an effective way to reduce carbon dioxide emissions. To achieve this, it is necessary to sort out the waste derived from vehicles, which used to be disposed of as ASR (Automobile Shredder Residue), and recycle each material separately. There are two important things to do in this process. One is to link the recycling chain of the venous industry (the industry responsible for waste treatment, disposal, and recycling), and the other is to build an IT platform (hereinafter referred to as “ITPF”) for its traceability and information management. In Japan, Toyota Motor Corporation, Honda Motor Co., Ltd. and Nissan Motor Co., Ltd. are in the process of building a recycling platform (PF) involving dismantlers and shredders in the venous industry. In this study, we analyze PFs in Japan and around the world, examine solutions to the issue of information distribution, consider how a global PF (GPF) should be formed, and propose solutions.

    By analyzing the descriptions of the diploma policies of professional universities in this study, we found that the diploma policies of professional universities have common items as institutions of higher education and degree training institutions similar to general universities, and are formulated by incorporating functions that produce professional human resources for the industrial society. Professional universities need to increase social awareness. We need to promote the development of programs that foster entrepreneurship with a focus on internships that develop practical skills and creativity and practical courses that are based on active learning.

    How can we quantify the differences between business models? It is the ultimate research question of this study. This essay reports on the possibility of using category theory as a method to achieve this goal. Specifically, when we consider a business model as an “object,” of category theory, we have shown that it can be represented by a structure called a monoid in mathematical algebraic structure, We report one more result that the business models are independent of each other in the sense of Leibniz’s monad theory.

    In the EU countries, young people who are NEET (not in Education, Employment, or Training) are currently recognized as a major social policy issue. Entrepreneurship is one of the career options for these young people. In this paper, the author summarizes the history of entrepreneurship support for young people as a measure against NEET in EU countries and how entrepreneurship support is provided in Italy, which has a high percentage of NEETs in the EU, through a literature study.

    In order to build the vision of engineering industry for sustaining regional city/community coping with super aging society in Japan, the new business research group in Engineering Advancement Association of Japan (ENAA) has been examining the future form of social infrastructure. Based on the perspectives of “Society 5.0”, “Smart City” and “Super City” projects in government policy, we focus the developing process of typical type of smart city cases. Therefore, we researched 31 proposal contents of municipalities, which applied “Smart City”. And conducting field survey and case analysis of typical regional cases, we are examining each case analysis from the perspective of the three layers of “SDGs vision”, “smart policy”, and “smart utilization”, to extract the relationship between the elements in each layer. Then, through comparing the results of chain analysis, we are approaching categorization about regional smartification towards SDGs vision. As a result of applying our research framework to the cases of Kaga City, we show a possibility of the methodology for further research.

    In each DMO, it is necessary to set management targets and evaluation indicators that are appropriate for each DMO by satisfying quantitative data and modeling and verifying evaluation indicators that go beyond the existing essential KPIs. It is also important to be skeptical of existing “essential KPIs,” to determine the nature and sustainability of DMOs, and to define new evaluation indicators. To this end, the construction of an evaluation model from quantitative research is required.

    The rise of mobile devices and improved network infrastructure are revolutionizing work and lifestyle through expanded remote work, including teleworking. This study focuses on Digital Nomads (DN) as a paradigm, addressing their “coliving” and synergy with local communities, using the Workation (WN) concept for reference. Results from a DN Living Learning Lab in Slovenia and a WN case in Wakayama Prefecture, Japan, were summarized. Findings highlight the balance between participant mobility and location dependency, while also considering collaborations with communities inside and outside of corporate organizations. These insights can indicate diverse DN and WN strategies, emphasizing local contribution, especially in a post-pandemic context.

    The aims of this article are analyzing two new movements of transportation industry, and proposing the tentative assumption of the curriculum for education into the transportation industry. What are he two new movements? The one is collaboration with other corporation and industry in rural transportation. The another is highly servitization in urban transportation. In addition, it occurs the decline of communitarianism, adopting IT, and getting closer to the airline industry.

    Our tasks are as follows. First, we must clarify the human resources image of our graduate. Second, we must questionnaire survey and interview for all train industries in Japan. And, we must refer the curriculum of college of aviation management in Obirin university. In next annual meeting, we will propose concrete curriculum map.

    With the increasing emphasis on open innovation, the importance of intellectual property (IP) strategy has long been advocated. Instead of using conventional means of exclusive monopolization or as a bargaining chip when rights are exercised, the active use of means such as licensing, assignment of rights, and free release of rights is recommended. However, executing a patent strategy involves careful considerations, including industry positioning and market maturity. The purpose of this paper is to organize prior research on open-close strategies and standardization strategies and present cases of their application at Toyota and Daikin. Additionally, it introduces three scenarios for the intellectual property strategy of the small and thin lithium-ion secondary battery, ‘EnerCera®,’ and explains their effectiveness.

    Japanese companies and society are facing many problems, such as the absence of leaders and the selection of appropriate successors. In general, the change in leadership style during the growth stage of a company is often referred to as the transition from an charismatic leader to a democratic leader. Therefore, in this research, we constructed a hypothesis about changes in leadership style accompanying the growth of an organization and tried to prove it.

    The hypothesis is to combine “Greiner’s corporate growth model” and “Situational Leadership Theory (SLT)” which considers leadership style, and to formulate the hypothesis that appropriate leadership styles at each growth stage of a company and should be selected according to the situations. Therefore, we attempted to verify the results in three cases.

    Companies that are continuing and expanding changed their leadership style according to the growth stage and the surrounding environment. But the company that was sold was not able to select appropriate leadership styles. In addition, it was common for all companies to shift from the “instruction leader” who instructs subordinates to the “persuasion leader” who supports subordinates, but after that, distinct types of leaders were selected depending on the situation.

    You can’t run a business with half-baked knowledge. I learned management of technology and was able to organize my knowledge of management in general.

    In technology management, I learned many things such as management philosophy, financial management, cost management, medium- and long-term management planning, new product development, and human resource development. And I can make use of it in my daily business activities. It was very meaningful for me, as a manager, to learn about technology management and organize it in this report.

    Currently, the TATAMI industry is said to be in decline, but changes in the times are also business opportunities. We aim to be a company that is needed by society by setting high goals and continuing to create products that meet the needs of the times.

    I am the second president of a small and medium-sized enterprise. I had the opportunity to study technology management and learned specific strategies to grow our company, which we have been working on for many years without growth.

    The company will not develop unless it formulates a medium- to long-term management plan, shares the plan with employees, and works on a growth strategy. Therein lies the logic of “technology management.”

    In order to become a management leader, you must first be able to lead employees as a person. Together with business administration, we strive to foresee the future and talk about dreams to employees. I learned that if you don't talk about big dreams and create a solid business plan to achieve your dreams, your business will not be viable.

    There are many examples of companies developing cross-industry platform strategies around themselves in order to form ecosystems. Some major manufacturing companies are also planning to promote industry platforms with a focus on digitalization, and some companies are promoting the building an ecosystem by focusing on collaboration with complementary suppliers. At the same time, the building an ecosystem is fraught with challenges. A typical example is the chicken and egg problem. A number of factors can lead to the chicken-egg problem. They may include appropriate multisided decisions, cleverness of the business model, relationships with complementary suppliers and the competitive situation. The purpose of this paper is to identify the factors that hinder the building an ecosystem from previous studies. It then looks at the medical industry and the diagnostic imaging case study of Siemens Healthineers and raises issues related to ecosystem building.

    After rapid economic growth, any society is faced with a series of structural challenges. Aging and population decline are the biggest issues in East Asia today. After losing World War II, Japan achieved rapid economic growth. In 1970, Japan entered an “aging society” (7% of the population aged 65 years old), and the aging rate continues to rise sharply thereafter. With the total population reaching a peak of 128.08 million in 2008, the aging and declining population will be the trend for the next 100 years. A similar trend can also be seen in other Asian regions, which have achieved growth following Japan.

    In this paper, we examined the commonalities and differences in the issues of the aging society experienced by Japan in comparison with the so-called "Greater China", such as Taiwan, Hong Kong, Singapore, mainland China, and overseas Chinese.

    As a result, unlike the welfare regime in Europe and the United States, in which social resources and costs are redistributed by the government centered on citizens' rights, a new social security system that responds to the impact of drastic changes in "population" due to urban demographics and family metamorphosis. The need for a regime became clear.
