There are many precedent researches about the going concern notice appeared in securities report, which is equivalent to Form 10K in the United States, but none was conducted in terms of survival analysis. This paper analyzes 296 companies with going concern over thirty-five quarterly results and categorizes them in six types such as bankruptcy, survival or reorganization to find out the difference in survival time between companies in traditional public markets such as the first section of Tokyo Stock Exchange and companies in emerging markets such as JASDAQ. Companies in emerging markets are usually regarded as less creditworthy than companies in traditional public markets because traditional public market requires harder rules than emerging market in terms of profit amount for the recent fiscal years before application. This paper analyzes bankrupt companies and delisted companies by utilizing survival analysis and concludes that companies in emerging markets go bankrupt in shorter term than companies in the first section and the second section of Tokyo Stock Exchange after going concern notice is appeared in securities report.

　Along with increase a variety of customer needs, treating of mass-customization is more topicality. However, for increasing variety of product to receive customer requirement, paradigm should be changed to be able to consider business according to circumstances. This paper proposes an improvisational approach for manufacturing management to respond flexible customer request. Also this approach is examined through some examples as realizing this consideration. As result, the effectiveness of this proposal is discussed through FBOM (fundamental bill of manufacturing) that can manage variety’s master data, managing the processing of an order with undetermined specifications, SEIBAN type production management and EDS (event driven simulation), and also manufacturing information system that adopts an improvisational approach.

　Deregulation is a first step in realizing a “growth strategy” to promote private sector investment and is often considered a powerful tool. One economic approach to this argument is the “mixed oligopoly” model. A typical conclusion therein is that privatization cannot be justified if the number of companies is not large. In this paper, we adopt to the mixed oligopoly model (1) an internalization approach of the “routine innovation” a la Baumol (2002) and (2) vertical structure which Hokari (2019) emphasizes as one of the characteristics of state-owned enterprises. As a result, in a “vertically integrated company” model, one of the typical form of vertical structure, it is shown that privatization is socially preferable even for the case of duopoly. This is because a privatized company makes cost-reducing investment and the total outputs increase.

　In today's discussion of Industry 4.0, we frequently find the word of MES (Manufacturing Execution System). MES is a system that appeared in the 1990s, which is not something new, but has existed in the center of the production systems in large factories. It is now becoming one of the most important words that a lot of people, including non-specialists in the computer and manufacturing field, need to understand to be able to discuss Industry 4.0. This is because these days the discussion of Industry 4.0 applies not only to large-scale factories, but to small and medium-sized factories as well. Moreover, this discussion has become widely talked about not only in the field of business administration such as marketing, management strategy, human resource management, etc., but in other social science fields such as labor economics. However, although there have been many technical interpretations of MES, there have been few previous studies that clearly explain why MES appeared as a new system in the 1990s, when computerization had been advancing. Therefore, in this paper, I would like to consider the reason why MES appeared and its background, using layman's terms as much as possible to be understood in various specialists’ fields.

　In this study, we used evaluation of physique, body composition, and a hierarchical fitness degree balance system to examine changes between the time of enrollment and graduation for newly-recruited male students at a firefighting academy. Results showed a decrease in the body fat percentage of the students. However, we clarified for the first time that the number of students in the “average, standard development of fat” group decreased and the number of students in the “lean, underdevelopment of fat” group increased. Based on these results, we found that reduction of body fat is effective for the “obese” group and the “excessive development of fat” group. However, for the “average” group and the “lean” group, we concluded that the prevention of excessive loss of body fat and the acquisition of muscle mass were the important themes for further improvement of productivity.

　There are three types of IoT human resources who practice IoT (Internet of Things) management: 1 strategy, planner, 2 development, engineer, and 3 operation, utilization person. At present, in Japan, the Ministry of Internal Affairs and Communications and private organizations are engaged in various discussions and IoT human resource development, but the IoT human resource development currently implemented is mostly for engineers. However, if a manager or user does not understand the creation of added value by IoT, it is difficult for the business strategy to penetrate the whole organization and to create the added value. In this research, we developed the goal of the human resource development program focusing on planners who can practice IoT management and users, and the procedure for using IoT added value creation map for education.

　In many schools, we can utilize in open campus to grow the motivation of the student. It is effective tools. However, if these games are used to the game to a certain extent, the other party is a machine, so the operability is more important than the contents of the game, and the original effect of the management game is lost because it proceeds without reading the explanation. It is important to play the game in a sense of presence and pressure that the machine is played by human beings and that the machine cannot obtain, so it will help to understand the contents of management.

　In this paper, we will develop a management game with educational effects using a board, and verify what kind of effects there will be by implementing it.

　Japan that has fallen into a labor shortage due to the declining birthrate and aging population, has enacted the revised Immigration Control Act in April this year, opening up simple labor for foreigners to 14 industries with a serious labor shortage of up to 340,000 foreigners in five years. 30 years ago, the Japanese yen fell into a recession, and the exporting company built an overseas factory and shifted overseas. Electrical companies also actively moved overseas, and shifted to less developed countries as the economies of the countries where they entered the country developed. However, the electrical industry has now been exposed to dust from China and Korea. Many foreign workers are currently visiting Japan because there is an economic disparity, so we must consider what to do with the labor force when the disparity narrows in the future. To that end, it becomes a problem how to replace the work currently performed by humans with machines. Automation of work, unmanned work and introduction of robots will be the key. In labor-intensive manufacturing industries such as food manufacturing, where mechanization is delayed, it is necessary to enhance production technology that supports factory automation, unmanned manufacturing, and robot introduction.

Governments around the world have agreed on Sustainable Development Goals (SDGs) that will show global priorities and the world's ideals for 2030. Companies are required to contribute through their core business. SMEs are also asked how to tackle social issues through their main business in the global demand chain.

Based on the analysis and consideration of the case of the sustainability report of one small and medium enterprise, the following strategic procedure is proposed as a business strategy for SDGs.

(1) Outside-in approach from social issues (2) Organization of business strengths and weaknesses (3) Assessment of impacts and risks on social issues SDGs (4) Determination of strategies to solve issues and take advantage of opportunities (5) Setting of key performance indicators (KPI) and business planning formulation and enforcement

(6) Going to the target of SDGs while reviewing milestones during the execution of business plans based on the setting of KPI (Key Performance Indicators).

　The majority of parents think that the cost of school lunch is around 2 to 300 yen. The reason is that the school lunch day is 20 days and the school lunch fee is about 250 yen per meal and about 5000 yen per month. However, the actual cost of school lunches is about 700 yen per meal in elementary schools and about 750 yen in junior high schools. Actually, the cost of lunch for parents is only equivalent to the actual cost of materials. Labor costs such as lunch cooks per meal and management costs such as utility costs and equipment costs are about 500 yen. Is this cost spent from taxes appropriate? What about cost performance compared to lunches served at restaurants, etc.? Who is the responsibility of management other than school lunch nutrition management and food hygiene management?

　Sports governance has lately attracted considerable attention. This is because, in sports, there are various scandals which is caused by sports organization, sports team, and athletes. The discussion has been progressing without making the object of sports governance clear. Although it is trying to use the discussion of corporate governance, it is not discussed carefully what is governance. In this paper, I studied sports governance from the viewpoint of business administration. The concept of governance is grasped in a broad sense.

Since revelations of illegal behavior by some Japanese companies after 2000’s, the studies about CSR have capture people’s attention． These studies emphasized sustainable relations with diverse stakeholders was critical factor for what firms have survived long-term． This insistence, since the concept of CSR constructed in 1920’s, have been remained doing repeatedly． Some empirical studies supported positive effects of CSR in Japan to corporate profitability． However, this result may be no relevance． Because the concept of CSR has had been expanded and transformed after occurrences of social problems such as some diseases by pollution, poor working environment and aging population and low birthrate in some developed countries． That is, this current broadly definition of CSR may not be same to past one． This paper re-examine preceding studies about the effect of CSR, especially empirical studies about CSR in Japan, with comparison of alternative views about CSR, positive view and negative view, theoretically． This examination will suggest what CSR companies should focus on, firstly．

　I conducted previous research related to business succession, an urgent social issue in Japan. In this study, the succession of business to third parties, which is increasing, is targeted. I compared and considered the successor in relatives and the third party outside in the entrepreneurial activity process of the family business successor presented in the previous research. As a result of the consideration , an analysis framework of the entrepreneurial activity process of business succession for third-party successors was presented. In the analysis framework presented, it can consider the impact on entrepreneurial activities such as balance, utilization, and constraints of these added resources that depend on third parties and resources that depend on predecessor management. It is an analysis framework that can consider the influence on entrepreneurial activities. Execution of analysis is a future task.
