We set up the following theoretical hypothesis that has never been studied so far; the altruistic transmitting information (ATI) in internet environment improves techno tentered and quality of life (QOL). It was investigated and analyzed statistically based on questionnaire surveys of university students in the information sciences, and the hypothesis was analyzed by the structural equation model. As a result, even though ATI was related to techno tentered, it turned out that ATI elevates QOL.

The purpose of this study is to analyze the potent influence on depression tendency caused by techno-centered tendency. We made a comprehensive study of stress, techno-centered tendency, depression tendency, loneliness and the purpose and the tool of the internet use. It was investigated and analyzed by the structural equation model based on questionnaire surveys of university students in the information sciences. The result verified that a rise in the techno-centered tendency causes the increase in the depression tendency. We also proved that the influence depend on the purpose of the Internet use. Moreover, it was shown that the adverse effect of the techno-dependency tendency was more than twice the stress effect. As a preventive measure against the depression tendency in the information society, we concluded that it is essential to prevent techno-centered and refrain from using the internet for escaping from reality.

The purpose of this study is to conduct regional revitalization and traditional culture by ICT.

In recent years, we are anxious about whether the young person’s conversation power decrease by an increase in the use of the Internet tool for communications according to rapid progress of informatization. Then, we set up the following theoretical hypothesis; even if the use of the Internet tool for communications increases, the conversation power doesn’t decrease enough to adversely affect quality of life (QOL). It was investigated and analyzed statistically based on questionnaire surveys of university students in the information sciences, and the hypothesis was analyzed by the structural equation model. As a result, it was verified that the adverse effect that the use of the Internet tool for communication caused for the conversation power was very small. However, if altruistic information in the Internet was not sent, the possibility of decreasing the conversation power was suggested.

In these days, organizations such as companies have to adapt to rapid environmental change in business in various way (divisional organization, SCM, SOA, outsourcing, etc.), but the way of current adaptation to the environmental changes does not work well. We propose a support system that is able to support in decision making of adaptive transformation in its own organizational structure based on collaboration among the autonomous resources (human, material, money, information). We define a set of the autonomous resources as an agent, and develop the support system in changing business environment, and evaluate its effectiveness. In this research, we develop a model that can describe a shift of organizations among centralized and decentralized structures, and simulate the shift in organizations by a multi-agent model, then discuss the results of simulation with respect to the effectiveness of our support system.

Cambodia is the constitutional monarchy nation located in the Indo-China peninsula which shares the east common border with Vietnam, the west border with Thailand, the north border with .Laos, and the south border with the South China Sea. The major industries of Cambodia are tourist business and manufacturing business including sewn products and shoemaking as well as the primary industry. As Cambodia attracts lots of attention as one of the countries for risk diversification of China +1 in recent years, investments from foreign countries are increased and economic development is shown though it is a least developed country. Today, China and South Korea are expanding their business positively in Cambodia to make a large sum of overseas investments on the society’s infrastructures and the real estates. On the other hand, Cambodia adopts the industrial policy of utilizing positive investments by the foreign capitals. The approach on an industrial cluster is seen on the industrial accumulation ground in the domestic special economic zone. In this text, we will examine the possibility of the industrial cluster formation in Cambodia with the major comparison of cases with two special economic zones in Phnom Penh and the Sihanoukville port.

How does the actual information-oriented society face the issues of resources limitation or ethics while protecting its advantages, such as freedom and diversity? We will try to resolve these issues through a positive thinking process in which we will analyze the concept of information. It is important to analyze nowadays communication as a gift rather than as a well-balanced exchange. Indeed, seeing communication as a gift, and knowing what is given in return, is a process that will show us its new value and its rethought meaning, both ideas that cannot be reduced to necessity or the money economy.

In this paper, we analyzed effects of defectives replies included in semantic differential data (SD data) on outcomes of analysis of the data. We prepared several data with different ratios of defective replies, through adding defective replies generated by a computer using random numbers to SD data obtained by an experiment. Applying Principal Component Analysis, we found that the proportion of variance of first principal axis declines rapidly and specific features of objects described by PCA become vague in proportion to the ratio of defective replies.

In this paper, we compare two types of semantic differential data (SD data), same layout data (SLD) and different layout data (DLD). SLD were obtained by using same layout of paired adjectives for all objects to be evaluated and DLD were obtained by using different layout of paired adjectives for each every object. According to analysis of these data, response times were longer in DLD , the ratio of responses to third category in 5-points response scale were higher in DLD and also differences among correlation coefficients between adjectives are smaller in DLD. These outcomes suggest that different layout of paired adjectives prevent respondents to construct cognitive space to evaluate objects.

The study analyzes discourses about “psychologism” and considers mastery of it. Since 1997, public schools provide control education taking psychological approach. Experts in psychology criticize such aptitude. However, they haven't offered alternative proposals. So, the study focuses on environments without their student's mind referring to discourses about “architecture”.

In this paper, we discuss the online community that attach points with user action. In fact, we compared two online recipe sites, one is point-grant and the other is not. We used text-mining analysis, and analyzed ingredients used in cooking. These two online recipe sites had differences of ingredients. Especially, recipes of the point-grant site had been optimized to get points by user.

The author clarified that relation between difficulty in human-relations and e-mail use of girls' high school students. As a result, there were 19 episodes of difficulty in human-relations related to e-mail use and we could classify them in six types. In addition, we found some episodes of maintained relations and the others broken off. In episodes of maintained relations, there were common territories in the real world, but there were no territories in episodes of relations broken off. Moreover, we found personal spaces in the Internet, and some girls had displeasure in being infringed on their personal spaces.

In late years the cases which a local government introduces social media such as Twitter into increase.
