This study demonstrates the educational effect of active learning for business people, using questionnaires of a supply chain management game. In the analysis, first, we classified player's educational effects by using machine learning and apply the player's strategy from questionnaires to the text mining. Next, we employ structure equation model using calculated index. The findings reveal that the strategy considering risks increases educational effects and the strategies an unwillingness to change decrease educational effects. This study demonstrates that risk awareness provides high education effect to players and indicates important guidelines for educational design for business people using active learning.

Many prior researches had pointed out that inter-and intra-organizational knowledge sharing in a supply chain(SC) is an important key factor for improving the performance of supply chain management(SCM). But how knowledge sharing affects the process of making efficient SCM strategies has not been researched. In this study, we focus on the analysis of how to make efficient SCM strategies after knowledge sharing by constructing and evaluating the system dynamics models for each strategy. And the comparison between different efficient SCM strategies not only indicates the importance of knowledge sharing on making efficient SCM strategies, but also clarifies the concrete effects of inter-and intra-organizational knowledge sharing on making efficient SCM strategies.

In recent years, with expansion and growth of E-commerce market, it is expected that the competition of getting customers will be fierce. Choosing appropriate target customers is very important for expanding sales and improving profitability. In this paper, we analyze customers' behavior using the web access logs and purchase records data on a gold EC site. Firstly, we evaluate the loyalty of customers using RFM analysis to divide customers into the loyal and general ones. Next, we perform logistic regression to discriminate loyalty by using the initial purchase and browsing behavior. Through our analysis, we clarify the characteristics of high loyal customers.

Pro-cyclicality means the economic cycle amplification effect. For example, it means that a mechanism such as "economic deterioration → deterioration of lending assets → capital shortage → suppression of lending → further deterioration of the economy" occurs.
In a previous study, there seems to be many views that lending declines have occurred with the strengthening of capital adequacy during the economic downturn after the collapse of the bubble economy. However, now the economic expansion period, the opposite mechanism should work, but according to the statistics, lending has not increased and this has not led to a further rise in the economy. Therefore, in this research, we will examine the relationship between capital adequacy regulation and loans using system dynamics method to explore the reason.

Diffusion of the Internet leads expanding EC market. On EC site, customer's reviews about product or service gives a great influence on purchase decision. So rating points and evaluation on review are expected to be utilized for marketing activities. In this study, we analyze reviews and rating points in a golf courses reservation sites and clarify the characteristics of positive reviews for the golf courses. Concretely, we used logistic regression to discriminate positive and negative reviews. In our model, the rating point to golf course is used as the objective variable. Moreover, we extracted some characteristic words from reviews and used these as explanatory variables. Through our analysis, we could clarify the effective reviews of golf course.

In the reconstruction process from large-scale disasters, economic support
is important because large-scale disasters may give serious damage on the economic situation of local residents. The primary purpose of this study is to conduct a simulation analysis of CFW programs implemented as employment creation project after the Great East Japan Earthquake.We elaborated a previous model to consider the impact on companies and workers in the labor market, and divided a model into three affected areas. We confirmed the model validity by fitting with labor market indicators at that time, analyzed whether the regional characteristics have an influence on the effect of CFW programs and whether the design factors of CFW programs have an influence on the labor market indices and the households that need economic assistance.

Prior research has shown great interest in the process and mechanism of innovation diffusion. This study demonstrates the influence of network position on innovation diffusion by analyzing “hanko," which were schools for clan retainers in the Edo period in Japan. We create an external knowledge network of hanko that was formed by ties when hanko taught the same subjects. We employ statistical analysis using network position indexes. The results contribute not only to revealing the adaptation process of new studies but to revealing the process and mechanism of knowledge transfer and diffusion.

Product design is the source of competitiveness that contributes to purchase intentions, word of mouth, payment intention. In the automobile industry, design has been regarded as important. In the design evaluation, companies often carry out Central Location Test. So, it is necessary to transport cars and prepare a venue of the scale capable of exhibiting multiple cars. In order to introduce each product globally, surveys overseas are also necessary, which places a heavy burden on companies. Therefore, VR is thought to be beneficial, but the influence on purchase intention is not sufficiently clarified. In this research, we evaluated the influence from the perception and the viewing behaviors for the purchase intention, then grasped the conditions for practical use of VR.

There, we thought of a method for college students, who are indeed millenials, to come up with the concept and idea of a washing machine by facing themselves alone. Since we were able to obtain an interesting design idea concerning the next generation washing machine, we will introduce it along with a detailed method in this paper.

In order to assess precisely the impact of workers' aptitude on productivity, we have made a series of experimental studies and questionnaires. However, because the workers were university students in all of these experiments and questionnaires, it is necessary to clarify whether the results of experiment questionnaire obtained from the student workers can also be fitted to general workers. In this paper, we hire 40 workers from the general public and conduct cell production experiment. Then, we make several statistical comparisons between student workers and general workers. It was clarified that the assembly times of student workers are generally shorter than the general workers.

This study focuses on firms' failure of recognition problem in innovation, especially when they introduce new technologies. As an interpretation system, firms develops information filters for efficient information processing, however due to those filters, firms sometimes hit roadblocks to develop skills to use new technologies. Steel industry is one of oldest industry and its history is the history of importing and implementing technologies, most of which are invented and developed in other countries and continents. However, not all firms are developers. Most firms "purchase" technologies and upgrade toward high grade products by "integrating" processes. This study elaborates on what makes process integration difficult, focusing on the linkages among manufacturing processes and recognition problem.
