Private financing is playing an increasing role in public infrastructure construction projects worldwide. However, private investors/operators are exposed to the financial risk of low profitability due to the inaccurate estimation of facility demand, operation income, maintenance costs, etc. From the operator's perspective, a sound and thorough financial feasibility study is required to establish the appropriate capital structure of a project. Operators tend to reduce the equity amount to minimize the level of risk exposure, while creditors persist to raise it, in an attempt to secure a sufficient level of financial involvement from the operators. Therefore, it is important for creditors and operators to reach an agreement for a balanced capital structure that synthetically considers both profitability and repayment capacity. This paper presents an optimal capital structure model for successful private infrastructure investment. This model finds the optimized point where the profitability is balanced with the repayment capacity, with the use of the concept of utility function and multi-objective GA (Generic Algorithm)-based optimization. A case study is presented to show the validity of the model and its verification. The research conclusions provide a proper capital structure for privately-financed infrastructure projects through a proposed multi-objective model.

The term "artificial intelligence" is considered a component of sophisticated technological developments, and several intelligent tools have been developed to assist organizations and entrepreneurs in making business decisions. Artificial intelligence (AI) is defined as the concept of transforming inanimate objects into intelligent beings that can reason in the same way that humans do. Computer systems can imitate a variety of human intelligence activities, including learning, reasoning, problem-solving, speech recognition, and planning. This study's objective is to provide responses to the questions: Which factors should be taken into account while deciding whether or not to use AI applications? What role do these elements have in AI application adoption? However, this study proposes a framework to explore the significance and relation of success factors to AI adoption based on the technology-organization-environment model. Ten critical factors related to AI adoption are identified. The framework is empirically tested with data collected by mail surveying organizations in Vietnam. Structural Equation Modeling is applied to analyze the data. The results indicate that Technical compatibility, Relative advantage, Technical complexity, Technical capability, Managerial capability, Organizational readiness, Government involvement, Market uncertainty, and Vendor partnership are significantly related to AI applications adoption.

Purpose: The purpose of this study was to investigate the factors influencing nurse turnover intention in small and medium sized hospitals in the metropolitan area. Methods: A cross-sectional survey design was used. A questionnaire was distributed to the nurses in small and medium sized hospitals. The data of 209 nurses was analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression. Results: Organizational commitment and age were identified as factors influencing turnover intention. These factors explained 56.8% of variance of turnover intention. Conclusion: Results suggest that establishment of organizational commitment needs to be discussed and continuously developed. Further study is also necessary to identify the key mechanism in nurse turnover intention.

Since it was found out that the degree of medical contribution to health was timid. the direction of health policy studies has been focused on the personal health behavior. Participation in health has been closely related to the behavior. Those who have insisted on the new direction believe that the health policy laying stress on low cost and personal responsibility can avoid the pathology of medical policy and medical crisis. Participation in health has been very important method of changing health behaviors. It is certainly important to change bad health behaviors. But there is no deliberation of social structure here. Most health behaviors are the adaptation to social structure. The attempt to change the established adaptation behaviors without considering social structure is difficult to succeed. It is little meaningful to say the importance of the health behavior to those who have no choice but to be ill due to the poor environment and health risks. What can guarantee the real direction of community participation at least is the consciousness and behaviors of people's right.

The purpose is to explore elementary students' attitudes towards money and the effects of parents' educational involvement on children's economic behaviors. The subjects are elementary students(N= 123) from first grade to sixth grade. The survey consists of question items of money ethics, attitudes towards money, consumer ethics, parents' attitudes toward economic education, and children's economic practices such as management of allowance, income, saving and savings account. The results are as follows: first, the elementary students show the double standard in attitudes to money, thinking of money as positively being important, at the same time, as being negative social value. Second, the parents play positive models in children's economic education. However, their efforts are not enough so that their children could have desirable economic habits. Therefore, economic education is first needed for the parents and then for children.

The managerial environment of automobile industry has been rapidly changing, mainly with the tighter standard of legal and environmental regulations, the pressure of cost reduction from the end-user, the various functional improvements of vehicles, and the globalization management. In order to survive in this complicate circumstances, the automakers have strongly pursued the mutual collaboration with the suppliers, especially tier-1, for the optimal selection of parts/materials and the assembly manufacturing processes of the new model development. They prepare the early involvement program for the suppliers during the conceptual design stage, and implement the win-win strategy of technology development activity, in order to improve the value creation. This study considers the strategic technology management of automotive steel sheets makers on the aspects of strategy, processes, human & physical resources, and organization structure. It also suggests the corporate strategies of steel mills, in order to obtain the technology competence.

The main purpose of this exploratory research was to examine the characteristics of consumers who patronize natural-dyed clothes and their perceptions regarding natural-dyed clothes. Thirty three participants who have worn natural-dyed clothes were interviewed for the study. They were asked about the styles and price of natural-dyed clothes they owned, their evaluation on them, and the lifestyles of themselves. Existence of subculture among the interviewes and its characteristics were also probed. The results indicated that natural-dyed clothes are relatively high-priced, mostly of modified hanbok style, and became popular in recent years. Interviewees frequently mentioned uniqueness and comfort as the main benefits of natural-dyed clothes, and expressed dissatisfaction regarding color fastness, easy care and problem of coordination. The consumers of natural-dyed clothes appeared to have strong preferences for environment conservation and Korean traditional culture. They also seemed to form a subcultural group who have commonality in their involvement in Korean cultural activities, mainly tea ceremony.

This work was designed for the Green Fund Aid 2004 of Korea Forest Service. It won the prize and has been constructed. We can have an opportunity to play a leading role in improving partnership with participation of local communities, promoting environmental education, and enhancing the environmental quality by constructing biotops in urban areas where energy flow in the ecosystem is not balanced. This design includes 'citizen participation process' and 'local community partnership' that is expected to promote local community participation in the process of design. This work suggests that biotope construction with citizen involvement and community partnership plays an important role not only in design items but also in the revitalization of local community. This sort of design process could not be fully achieved without cooperation with stakeholders - environmental specialists, local authorities, relevant societies, schools, teachers, parents of students.
