The mass media and people related to education have argued about the results of the Japanese national survey of academic performance which the Ministry of Education, Culture, Sports, Science, and Technology administered; paying attention to the low scores in Osaka prefecture. This paper, does not discuss countermeasures by prefectures, but analyzes the available quantitative data. By using multi regression analysis when letting academic performance be an objective variable, we find some effective explanatory variables. Also by factor analysis with factor loading amount, we can clarify the position of each prefecture and reveal the factors that affect the scores of students. We believe that this research can enable our compulsory education system to achieve higher scores in future.

Instant noodles were invented in Japan in 1958. Since then more than one hundred billion meals of ramen noodles have been consumed all over the world. China, which consumes about half of the world consumption, is the biggest market. The biggest food company in China, Master Kong, was founded in 1992. Although the company has a short history, it has grown rapidly to reach almost the size of world-famous food companies such as Coca-Cola. We analyzed the consumption structure of instant noodles in Japan. Also, we analyzed the Chinese economy which has supported the high growth rate of Master Kong. Finally, after the analysis of the financial status of Master Kong in recent years, by comparing it to the Nisshin Foods Company, which invented instant noodles in Japan, we will discuss how Master Kong might be managed in the future.

When Lehman Brothers went bankrupt in 2008, as in previous global financial crises, we could see that all banks expanding internationally tended to have closer linkage with global markets to perform balance-sheets adjustments. In recent years, the Nikkei stock average has been influenced by international linkage a lot. We analyzed the movement of shareholders by using the data of the Japanese distribution of dividends to shareholders. From factor analysis for the transition of investment ratio of each department, we could explain the actions of investments. Also, we performed multiple regression analysis to analyze the linkagebetween the Nikkei stock average and foreign stock market indices using the Dow Jones average, the S&P500, and the SSE composite indices as explained variables. From these results, we succeeded in showing the international linkage of Nikkei stock average by using statistical data.

The cellular automaton was created by John Von Neumann and Stanislaw Marcin Ulam. What Von Neumann was interested in was a machine which could replicate itself and the first such machine in the logical world was the Neumann cellular automaton. Since then, the cellular automaton has been expanded to many fields such as biology, history, and complex systems. This paper suggests closed social structure models with the method based on the cellular automaton. We succeeded in finding some interesting facts using simulations. The results gained can be applied to models such as closed social structures nowadays or the existence of living creatures.
