  • This study reviewed the planning characteristics of contemporary Japanese middle school architecture on which related studies are insufficient, aiming to obtain new ideas for planning Korean middle school facilities. Fourteen case schools built after 1990s were selected and analyzed. They were divided into learning-living space and other major spaces. The planning characteristics of the case schools are summarized as follows 1) The case schools were classified into two categories, departmentalized classroom type (D type) and usual with variation type (UV type) by school system. These categories can also be the classification standard for basic architectural characteristics in learning and living space of case schools. 2) D type case schools have departmentalized classrooms, home base, media space and teacher's space for learning-living space. D type case schools are divided into 'attached-to-classroom type' and 'separate type' depending on the adjacency of the home base and departmentalized classroom. 3) UV type case schools have multipurpose space around the classroom for learning-living space and can be divided into two types, i.e., 'directly adjacent' and 'separate', depending on the connectivity to classroom of multipurpose room. 4) Specialized classrooms are designed to have the openness to the public and the own characteristics of school subjects strengthened and show the spatial differentiation with connected ancillary spaces. 5) Libraries are designed as complex zones grouped with computer labs, audio visual rooms and multipurpose halls not as a single room and as open plan not with a closed wall. 6) The gymnasium is the basic sports facility with a martial arts room and outdoor pool, which are for after-school activities as well as physical education class. 7) The terrace, balcony and outdoor stairs are frequently used architectural vocabularies as diverse outdoor spaces with a variety of functions.

  • This research is to analyze the spatial information search features which shown by Eye fixation and movement and conducted eye tracking experiment for targeting sports shop spatial images which it are same but looks different. This is able to find out the eye movement feature according to placement of goods from the eye movement and movement distance of spatial visitor, and the result can be defined as following. First, the whole original-reverse left / right images have a higher number of observations in the [IN] area than in the [OUT] area. This is because after eye taking high observations in LA area of [IN] have been jump-over [OUT], performed search activities in low eye fixation without high eye fixation. Second, there was a difference in the frequency of the observation data as the composition of the images changed. The original image has been often fixed the eyes in LA area, and the one that has been observed for a long time is reverse left / right image. Also, fixation point was shown higher at the reverse left / right image as jump-over from [OUT] area to [IN] area. If LA area seen as reverse left / right image, it is located in right-hand side. The case where the dominant area is on the right side has a characteristic that the eye fixation is longer. This can be understand that the arrangement of products for attract the customer's attention in the commercial space might be more effective when it is on the right side. Third, the moving distance(IN ${\rightarrow}$ OUT) of the sight pointed to external from LA area was long in the both original-reverse left / right images, but it is no relation with search direction([IN${\rightarrow}$OUT] [IN${\rightarrow}$OUT]) of the sight. In other words, the sight that entered in LA area can be seen as visual perception activity for re-searching after big jump-over, in the case go in to outward (OUT area) after searching for more than certain time. The fact that the moving distance of eye is relatively short in the [IN ${\rightarrow}$ OUT] process considered as that the gaze that stays outside the LA area naturally enters in to LA area.

  • A performance analysis was conducted according to changes in inflow velocity and the tip speed ratio of a portable horizontal-axis hydro turbine that can be used for marine leisure sports and outdoor activities by using the commercial computational fluid dynamics software ANSYS CFX. By using the analysis result and flow field analysis, the design was reviewed and the performance of the device was confirmed. In addition, data necessary to improve the performance of the hydro turbine were acquired by performing an additional performance analysis according to the variable blade pitch angle. The results among the numerical analysis cases show that the highest performance at all inflow velocities and blade pitch angles if achieved at a tip speed ratio of 4. The output power was found to be 30 W even under some conditions below the design flow rate. Among the numerical analysis cases, the highest output power (~ 85 W) and power coefficient (~ 0.30) were observed at an inlet flow rate of 1.5 m/s, a blade pitch angle of 3°, and a tip speed ratio of 4.

  • Understanding customer' lifestyles important for banks because it will guide in determining marketing policies, such as services, pricing, service delivery and promotion decisions. From the customer' lifestyle, banks will know what kind of customers' attitudes, interests and opinions, so they also will understand what the costumer' needs and what services needed by them. For Islamic banks, customers understanding are important because, nowadays, the competition of the banks is not only with other Islamic banks but also with the well-established conventional banks offering Islamic products or services The aims of this research paper are to describe what factors underline the customer's lifestyle of both Islamic and conventional bank, to segment the bank customers based on their lifestyles and investigate the profile of each segments, to compare the characteristics of the segments, and to identify marketing policies based on the characteristics. The population of the study is banking customers in Indonesia, in which the researchers have used judgment sampling as sample selection. There were 186 customers of Islamic banks and 244 customers of conventional bank as respondents in this study. Statistical methods employed were exploratory factor analysis and cluster analysis. The finding of the study shows that there are twelve factor underlining the customers' lifestyle, namely: factor of fashion conscious, internet usage, sports spectator, financial and technology optimism, price sensitivity, independent, compulsive housekeeper, new brand tryer community activities, opinion leader, credit usage, and homebody. In addition, for Islamic banking, there are two market segments, namely fashionable-independent and innovative-social segment. Based on the lifestyle characteristics, the first segment has higher level in factor of fashion conscious, homebody, independent, optimism and price conscious, which is therefore called fashionable-independent segment. On the other hand, the second cluster has higher level in factor of new brand tryer, community minded, sport spectator, credit user, internet usage, opinion leader, and compulsive housekeeper, which is therefore called the innovative-social segment. Furthermore, for conventional banking, there are also two segments, namely persuasive-optimistic and sensitive-independent segment. The first segment has higher level on some factors, namely: opinion leader, optimism, internet usage rate, credit usage level, sport spectator, and new brand tryer. On the other hand, the second cluster is characterized by higher level in factor of price conscious, confidence, community minded, homebody, fashion conscious, and compulsive housekeeper. Managerial implications for the management of Islamic banks could be identified in this study as follows. Firstly, the twelve lifestyle factors of this study could be an alternative view in observe Islamic banking customers. The domination of both the fashionable conscious and the internet usage factor show that the aspects are quite instrumental in perceiving the customer' lifestyles, in which reflects the importance of these two aspects to customers. Secondly, in serving their customers, Islamic banks need to understand the customer lifestyle, in which the lifestyle segments found in this study provide a guide of how their needs were reflected. Finally, by understanding the segments and the characteristics each segment of the conventional banks, Islamic banks could adjust their marketing strategies differently from the conventional banks.

  • With today's heightened interest in quality of life, leisure and sports activities were popular in the general public. Accordingly, the incidence of oral and maxillofacial injury are also rising. Use of a mouth protector to prevent the trauma of the oral and maxillofacial region is growing in importance, and among the mouth protector the mouthguard is the most commonly used. Mouthguard has been suggested to protect injuries by (1) preventing tooth injuries by absorbing and deflecting blows to the teeth; (2) shielding the lips, tongue, and gingival tissues from laceration; (3) preventing opposing teeth from coming into violent contact; (4) providing the mandible with resilient support, which absorbs an impact that might fracture the unsupported angle or condyle of the mandible; (5) preventing neck and cerebral brain injuries. Although mouthguard is effective for prevention of oral and maxillofacial injury, it is not widespread to athletes or general public and they are lack of awareness about the importance of mouthguard. We present the types and materials of mouthguard, things to consider when mouthguard fabrication, and the usage. This should be helpful in awareness about the importance and popularization of mouthguard.

  • With the changing safety services and social order systems accompanied by the economic development and changing public security environment since the Chinese economic reform, the security service industry in China is growing daily and related problems are increasing. For the Chinese security service market to be activated, the monopoly of security services by the public security agencies must be removed. In addition, the research and development, expansion, and applications of safety and crime prevention technologies regarding the safety and protection of exhibition, sales, culture, sports, commerce activities, combinations of safety technologies and crime prevention processes, the provision of relevant technical operations, and the expansion of security service areas are required. Furthermore, the administration rights, property rights, and business management rights of security companies must be separated, the security headquarters must be integrated and coordinated for optimization of various resources solely by market needs, and their rights and affiliation relations must be clear. Besides, the competitiveness of security companies in the security service market must be enhanced by unifying the business management, and optimizing and sharing their resources. The security service ordinances of China that have been implemented now must be applied realistically, methods to activate the true market economy for security services must be researched, and various ordinances related to security services must be realigned in line with the characteristics of security services. Finally, for the mutual cooperation system between public and private security services, the public security agencies must acknowledge the importance of private security services and the status of security service providers in crime prevention and social order maintenance. They must establish partnership relations with each other beyond the unilateral direction and management system for security services and drive with positive attitudes the security service industry which is still in its infancy.

  • These days utilization of copyright in daily life and economic activities is becoming more important than ever, and IT technology is developing day by day. Along with those fact, copyright infringement and dispute is naturally increasing. This thesis dealt with the 3 different issues of ADR on copyright. The First part, introduce ADR system that was performed by Korea Copyright Committee according to Copyright law. This paper evaluate the committee's efforts to provide resolution of copyright disputes via conciliation was effective. So it needs to be look over several countries' ADR, beside conventional judicial remedy. And Korea's copyright conciliation system which is successfully operating also introduced. Second, In many countries, including South Korea are take advantage of conciliation as the way to settle down the dispute over copyright. Furthermore, looked over if we can use arbitration as tool to settle dispute or not. Currently in Korea, patent dispute is handled by Industrial Property Dispute Conciliation Committee(The Invention Promotion Act Ch.5) and Layout-design Review and Mediation Committee(The Act on the Layout-designs of Semiconductor Integrated Circuits Art.29-34), but using performance of those two committee is still too low. In comparison, the copyright committee, a affiliation organization of the ministry of culture, sports and tourism has much more result in conciliation compare with patent dispute. Copyright disputes has arbitrability of it's subject-matter and many regulating organs are interested in it. (especially, binding of arbitral award and final resolution). Take advantage of both conciliation and arbitration could be good way to resolve copyright disputes. Third, the writer look at the proposal on the creation of Northeast Regional Center for Intellectual Property ADR. Because of the nature of copyright and rapid development of internet technology, international use of work become more frequent and accordingly infringement cases are increasing. The role of commercial arbitration regimes and institutions which has progressed significantly worldwide level, but which has only just begun in the intellectual property ADR area, leads also to a clash of often very different legal cultures and protection in a market economy. International cooperation in regional area with conflict interests becomes an important alternative. But it will depend on the building of regional institutions and mechanisms. The feasibility of this proposal and preconditions were examined. Establishment of new international organization requires a lot of time, cost and efforts. And risk of failure is much too high. Therefore factual, statistical review should be preceded. In addition, technical measures, such as on-line arbitration is necessary to review also. Furthermore in order to establish new organization, the relative law, legal environment, public sentiment and international compliance must be carefully considered with factual review about the needs and economic benefits of each country Yet on complex regulatory matters such as IP and ADR, a great deal of the potential benefits from international standards arises not from the international legal framework nor even the formal content of national legislation, but from the informed and effective use made of the possibilities within the system, including by policymakers and regulators.

  • The purpose of this study was to investigate effects of academic stress levels on life-style behaviors and mental health among the junior high school students in Korea. A convenient sample drawn from the 842 students from 8 junior high schools in Seoul and Kyunggi-Do area was investigated with a survey instrument. Female students showed higher academic stress levels compared to male students, especially in terms of the stress related to teachers, class time, and peer relationships. For the male students, higher stress levels were related to the higher risk factors of smoking, drinking and inhaling drug abuse. Students who had higher academic stress levels spent more time in using computer and playing digital games compared to those who had lower academic stress. In addition, higher academic stress levels were significantly related to risk of mental health, especially depression. These results suggest the urgent needs of preventive or educational program to support students with academic stress resolve in healthy manners such as playing sports or music or club activities.
