    This study investigates how a company may maintain a high Occupational Safety and Health (OSH) standard through the fourth industrial revolution. Therefore, this study focuses on the impact of firms' R&D capabilities on OSH, which is based on knowledge management strategies. The analysis involves data from 100 U.S. companies in the manufacturing sector. The data describes incident rates, R&D activities, as well as investment in new technologies. This study demonstrates that although high R&D capabilities always promote OSH, low R&D capabilities with high investment in new technologies greatly impairs OSH. This study provides theoretical contribution to absorptive capacity theory and safety research as well as practical contribution to safety strategy for companies.

    In this research, we analyze the Wi-Fi log created every day in the recent widespread Wi-Fi environment, and make an effort to acquire user behavior. First, since Wi-Fi log will be huge and a calculation time to get users transitions will be very long, so we propose an algorithm for calculating the transition probability matrix and show a calculation time as a guideline for . Moreover, in order to confirm an ergodicity, that is the basic property of Markov chains, from the obtained transition probability matrix, we clarify a relationship between sites from a directed graph. By using basic properties of Markov chains of the transition probabilities obtained from Wi-Fi logs, we aim to get users behavior.

    The purpose of this research is to measure the competitive advantage period and the value of intangible assets which have been difficult until now. A model combining RI and CAP was constructed as a measurement method with objectivity and feasibility. The average CAP for each company revealed the cycle length, growth and decline of each business. Also, new indicators such as intangible assets per capita, and CAP were obtained. There is a contribution that can complement the part that indicators such as ROE miss. Introducing the concept of imaginary time, which is negative time, enables analysis with a high amount of information. It was possible to show that the conventional macro aggregation cancels out the positive and negative numerical values.

    This research focuses on the raw materials trading and technology insertion networks of the Japanese petrochemical industry. Although there is overlap in knowledge, this study demonstrates the influence of both networks formed between companies with completely different relationships on research and development (R&D) capability. The study uses indexes calculated using network analysis for two years in 2009 and 2013 and performed a negative binomial regression model analysis. Each centrality index of both networks not only improved R&D capability, but also had an interaction effect. Demonstrating the use of multiple different corporate networks in combination not only contributes to network theory and absorptive capacity theory, but is also a practical contribution to innovation strategies.

    In commercial facilities such as department stores and shopping centers that have multiple tenants, it is important not only to improve the profit of a single store but also to improve the profit of the entire commercial facility. We propose an optimization method of marketing resources by considering the cascading effect of store use. Using this method, we can estimate and extract stores and prospective customers that should be prioritized for sales promotion, and then we can understand the characteristics of customers on store visits. By applying this method to the actual purchase history, we estimated the number of store visits by customers, understood the customers' characteristics, and extracted stores/customers who should intervene.

    This research focuses on the impact of communication in the virtual laboratory on students' motivation for the research. A structural equation modeling was constructed using the questionnaire results from 41 students using the virtual laboratory. The students can feel someone close to them even if the virtual laboratory is designed in two rather than three dimensions. This illusion brings active interaction among students. This study demonstrated that this interaction among students generates a feeling of unity as an organization and increases their research motivation. In conclusion, the results suggest that a virtual laboratory can be leveraged as an educational tool even after COVID-19.

    Increasing the number of university spin-offs that commercialize university research and technologies has become a challenge and universities have gradually adopted RA (Research Administrators) to support spin-offs. This study demonstrates the impact of the diversity of RA's experience on the increase in spin-offs. The data were from 401 universities in Japan in 2018. We demonstrated the number of RA, the diversity of RAs' previous work experience, the percentage of long-term employees, and the training system positively impact the number of spin-offs. This study theoretically contributes to the resource-based view by quantitatively demonstrating the effectiveness of RA and practically contributes to making strategic recommendations from results of interaction effect for the effective operation of RA in increasing spin-offs.

    The “liability of newness" makes a venture firm's cash flow difficult. We demonstrate the impact of quick profitability on a university-originated venture firm's representative and university attributes, location of establishment, and related researcher. We use data obtained by the Ministry of Economy, Trade, and Industry from 115 firms between 2016 and 2019. A multiple regression analysis shows that it is easy to profit when the representative is a researcher. Furthermore, we examine the effect of the interaction between the attributes of the representative and those of the university. This reveals a prompt surplus mechanism. This study is a theoretical contribution to the study of emerging entrepreneurs, and it makes a practical contribution by presenting a strategy for establishing university-originated ventures.

    We predicted daily stock price fluctuations in the Japanese market based on inter-firm relationships and examined the predictability of stock price changes between the normal and the corona shock period. Using Japanese securities reports, we examined the impact of stock price fluctuations on one firm's stock price on the other. As a result, we successfully predicted these fluctuations on a daily basis. In addition, the alpha value of the stock price fluctuations in the corona shock period was larger than those in normal times, suggesting that the effectiveness of the stock price predictability is higher. In particular, a significant impact on the stock price fluctuation was observed in a customer-to-supplier relation, a downside event, and/or a case in which the customer company is a large corporation.

    The purpose of this study is to record, predict, and deliver beautiful moments in everyday landscape, and to derive potential tourism resources. We re-evaluate our everyday landscape, focusing on the sunset. First, we calculate a color distribution using RGB distance from teacher images. Next, we calculate a similarity of a color distribution between image of the fixed-point camera and teacher image to obtain a degree of beautiful sunset. Next, forecast dataset is created from open data, and this model is constructed using a stepwise method and logistic regression. This case, we confirm that there is more than 80% probability of forecasting a sunset. In the future, we will make this model able to use everyday landscapes as local tourism resources.

    Swiftly submitting a product recall notification reduces subsequent damage. This study demonstrates the influence of outside directors and whistleblowing on such submission. We use 111 notifications from 15 automobile industry firms in Japan in fiscal year 2019. Multivariate analysis shows that a high ratio of outside directors and frequency of whistleblowing have a negative effect on notification submission. We also examine the interaction effect between the outside director ratio and whistleblowing. The analysis reveals that outside directors have a positive effect on submission when whistleblowing occurs frequently, but otherwise have a negative effect. This study makes a theoretical contribution to top management team research and a practical contribution by proposing an effective outside director ratio and whistleblowing system.

    This study demonstrates the impact of the halo effect on renewing contract of Foreign Employees in Meiji, Japan (“Oyatoi-gaikokujin"). The halo effect is the tendency of existing evaluations to influence subsequent ones. We used financial data from 1874 to 1876, and the directory. The results reveal that due to the halo effect, high education and past performance earn higher pay, but result in less than expected outcomes; meanwhile, those with lower expectations are more likely to be rehired. This study contributes to the theory of cognitive bias by demonstrating the halo effect, which is difficult to quantify and made a cross-disciplinary contribution to the field of Japanese history.

    The interventions implemented in each region to prevent the spread of COVID-19 depend on a great many factors. In order to estimate the effects of the interventions, a large number of those factors need to be analyzed in combination. Fujitsu Laboratories have developed Wide Learning which can search for combinations of data items exhaustively and rapidly to find out important combinations. Using this Wide Learning, we analyzed the success or failure of the interventions in each region through August 2020. Furthermore, based on the results, we use a what-if analysis to estimate the effect of each intervention in each region and at each point in time.

    DX can be pertinently defined as "mastering the use of data and IT to create new value." The senior management plays an extremely important role in DX organizations, there is often a lack of appropriate human resources within such organizations; hence, it is necessary to hunt talent from outside the organization. Satisfactory annual salaries and work freedom are essential requirements when recruiting human resources in order to ensure competitive strength. In addition, a management that delegates human resource recruitment decisions and organizational operations to a DX organization, avoids micromanagement of human resources, and permits freedom with tolerance for mistakes is essential for promoting the creation of new value.

    In this study, we propose a valuation method for the similarity of firms and apply it to the valuation of unlisted firms. In this paper, we propose a new valuation method for non-listed companies based on the similarity of sales, operating profit, and ordinary profit with the target company. Based on the comparable company method, we aim to improve the valuation accuracy by creating a new indicator, the degree of similarity. Since we are considering to apply our method to unlisted companies as well, we select the financial data to be handled, and aim to propose a new enterprise value evaluation method. In this presentation, we use only the financial ratios as a measure of similarity, but we also consider weighting each financial item.

Although there are many kinds of production planning software for production planning, they are not used in SMEs. It is because these kinds are expensive and have no sufficient functions for the enterprises. In the existing conditions, experience and repetition of trials and errors make the planning of production schedules possible. Therefore, we propose a tool which supports heuristics scheduling by directly inputting to a Gantt chart with no use of conventional approaches. In this paper are reported the design contents of our trial system and the method for operation efficiency and automation by use of Robotic process automation (RPA).

    Effective utilization of external knowledge is important for innovation creation. Recently, the concept of reabsorption, where an originating firm reabsorbs its spilled knowledge, including the advancements made by recipient firms, has attracted attention. Although existing studies analyzed the impact of reabsorption on the number of patents, the impact of reabsorption on patent value is not sufficiently clear. In addition, the impact seems to depend on reabsorbing what kind of knowledge. Therefore, this study attempts to clarify the impact of reabsorption on patent value focusing on knowledge similarity.

    In recent years, due to technological progress and changes in social conditions, the transition to an online environment for organizations is rapidly progressing. In particular, in universities, human relations are weakening, and the amount and quality of support that people receive is declining. Mentoring is a representative form of the developmental relationship between mentors and prostheses, and is beneficial to both mentors who provide support and those who receive support. In order to build a lively relationship like the conventional offline environment in the online environment, the concept of emotional contagion in psychology is applied to investigate the contagion of mentoring. A case study will be conducted in a university laboratory, and through analysis, how existing mentoring will affect others will be clarified.

    It is becoming clear that humor has multiple and significant meanings and functions in our daily lives. Although much research exists on a sense of humor as defined by individual personalities, there is a lack of research papers on the ability of humor to be defined by interrelationships within organizations. Previous research has shown that joking behavior is facilitated by the perception of joking relationships. The promotion of individual joking behaviors may improve sense of humor in organizations. In this study, we conducted a questionnaire survey using the MSHS for humor and a questionnaire for the perception of joking relationships, and clarified the correlations between each factor of MSHS and the sense of understanding and acceptance of others.
