Since 1795, 106 districts in Japan have been selected as Important Historic Preservation Districts (Juuyo dentouteki kenzoubutsugun hozon chiku [Juudenken]). The system for protection of cultural properties enables the local government to name a "Preservation District" and allows for the development of a preservation plan based on local ordinances. Moreover, the well-organized, bottom-up networks, which are groups for community development activities on the basis of local participation, play an important role in raising awareness and conducting several preservation projects in their own towns. This study mainly focused on cultural resources management in the local community. The system, which possibly bridged the gap between the local authorities and the community, was revealed. Fifty non-profit groups and active citizens, who were engaged in an advanced stage of community participation in Juudenken, were selected to be interviewed. The results then were analyzed using STAT program. The significant associations were shown by mapping the associations related to the public process of community involvement. Each variable had its own significant meaning and contributed credible indirect association to community involvement. The network mapping indicated that balancing the local economy and technical conservation was important in generating community involvement, which provided a model on how local authorities and communities could articulate and maintain their own cultural resources.

Purpose - Since Iran's economy is only now developing, and its stock market is only now emerging, we should deal with the relationship between ownership structure and conservative accounting of companies to see whether such a relationship exists in Iran's market. This study aims to investigate the relationship between ownership structure and accounting conservatism of listed companies on the Tehran Stock Exchange. Research design, data, and methodology - All listed companies on the Tehran Stock Exchange, for which the required information financial statements (balance sheet, profit and loss account) could be acquired for the period 2007-2012, were studied. A total of 123 companies from various industries was selected. Results - In order to test the hypotheses, multi variate regression (inter procedure), with their meaningful t- and f-statistics, and a Durbin-Watson autocorrelation model were used. Conclusions - The research results show that the ownership of major shareholders and ownership concentration have a negative significant relationship with accounting conservatism. Therefore, as a significant negative relationship between concentration of ownership and accounting conservatism at the 95% confidence level was found, the second hypothesis was confirmed.

This paper investigates the determinants on decision to conduct seasoned equity offerings (SEOs) of listed companies on the Ho Chi Minh Stock Exchange in Vietnam. Seasoned equity offerings (SEOs) are defined as the issue of more stocks by a firm to raise more capital after a primary issue. Using panel data collected from audited financial statements of 99 listed companies on the Ho Chi Minh Stock Exchange during 2014-2018, the study employs a logit regression model by fixed effects method to examine factors that affect the decision to implement seasoned equity offerings of those companies. The findings of this study show that profit, revenue growth and company's size have a positively significant impact on the decision, while dividend pay-out ratio negatively significantly influences the equity issuing decision. Furthermore, these results are robust after controlling for the forms of equity offerings, i.e. bonus stocks, stock dividends and rights to buy shares. These findings are consistent with economic theories such as agency theory, pecking order theory, and growth opportunity theory, and also could be explained by the real situations of the Vietnamese stock exchange. This study has important implications for corporate managers, policy makers and investors.

Purpose: Evaluation of the creativity level of design concepts. Methods: 14 winners of design concepts area of the 2015 Red dot Award are used to evaluate the creativity level of design concepts. Among the 14 winners, one is the highest award (; luminary) winner, 4 are the second highest award(; best of the best) winners, and the remaining 9 are winners. AHP model was developed to evaluate the creativity levels of design concepts, and applied to the 14 winners of the reddot award. Results: Originality and practicality have been used to evaluate creativity level of new product ideas in the previous study. In this study, it is identified that originality is composed of innovativeness and topicality, and practicality is composed of utility and realizability. The design concepts which won higher level awards have higher level of originality. Among the two dimensions of originality, topicality has more significant relationship than innovativeness. Conclusion: The design concepts with higher level of originality, especially higher level of topicality, have a fair chance to be recognized as creative. It is notable that higher level of originality does not guarantee higher profit. According to the previous studies on the commercial success of new products, practicality is more important than originality.

In current IEEE 802.11 wireless LAN, every unicast transmission requires an ACK from the receiver for reliability, though it consumes energy and bandwidth. There have been studies to remove or reduce ACK overhead, especially for energy efficiency. However none of them are practically used now. This paper introduces a noble method of selective unacknowledged transmission, where skipping an ACK is dynamically decided frame by frame. Utilizing the fact that a multicast frame is transmitted without accompanying an ACK in 802.11, the basic unacknowledged transmission is achieved simply by transforming the destination address of a frame to a multicast address. Since removing ACK is inherently more efficient but less strict, its practical profit is dependent on traffic characteristics of a frame as well as network error conditions. To figure out the selective conditions, energy and performance implications of unacknowledged transmission have been explored. Extensive experiments show that energy consumption is almost always reduced, but performance may be dropped especially when TCP exchanges long data with a long distance node through a poor wireless link. An experiment with a well-known traffic model shows that selective unacknowledged transmission gives energy saving with comparable performance.

In recent years, the market for online computer games has become an important part in the entertainment industry. New online games have been introduced every month and the numbers of game players who are playing online games have grown rapidly. However, only a few online games have been successful in making a good profit among many online games. Why are most players playing only a few online games repeatedly? To answer the question, this research focuses on the customer loyalty and their optimal experience(flow) in playing specific online games. This research hypothesizes that customer loyalty for specific online game can be increased by customers' optimal experience(flow) in playing it, and they would feel optimal experience because of mechanic and social interaction in online games. In order to validate the hypothesis, this research analyzes online survey data of players of various online games. According to this survey results, players' optimal experience is affected by their mechanic interaction between a player and an online game system, and their social interaction with other players who participated in the online game. And their optimal experience during playing the online game affects the degree of customer loyalty to the game. This paper ends with conclusions of the survey results and study limits.

Private security will be of great importance in the coming 21st century. In the future, most of the crimes will be violent and frequent. In order to prevent crimes private security must be dealt with in public service area and private area. For this reason, nowadays studies on private security is going on actively. But in reality, serious studies on theoretical backgrounds of private security has not been made yet. Currently, almost all of the theories propose various grounds, such as administrative, economic, and social grounds. And they are based on five backgrounds, that is, profit-oriented enterprise theory, economic reduction theory, vacuum theory, interest group theory, and private management theory. The article furnishes several grounds in addition to these. They are local self-government, management of local self-government, and task-force of guard enterprise. In this article, I am going to present some perspectives in classifying the theories. They are administrative, economic, and social perspective. They are shown as follows by figure. In conclusion, based on theoretical backgrounds mentioned above, private security will be advanced constantly in the future. But in carrying out studies on private security, approaching method of proposing the developmental model is more important than theoretical approaching method.

The restructuring of power industry is still going on all over the world for last several decades. Many kinds of restructuring model has been studied, proposed, and applied. Among those models, power pool is more popular than others. This paper assumes the power pool market structure having competitive generation sector and a new method is presented to build bidding strategy in that market. The utilities participating in the market have the perfect information on their cost and price functions, but they don't know the strategy to be chosen by others. To define one's strategy as a vector, we make utility's cost/price function into discrete step function. An utility knows only his own strategy, so he estimates the other's strategy using stochastic methods. For considering these conditions, we introduce the Bayesian rules and noncooperative game theory concepts. Also additional assumptions are included for simplification of solving process. Each utility builds the strategy to maximize his own expected profit function using noncooperative Bayesian game. A numerical example is given in case study to show essential features of this approach.
