The purpose of this study is to analyze the effect of public transit accessibility on the Carsharing use demand. By utilizing the rental historical DB of Greencar which is operated in Suwon city and public transit GIS DB, the use demand models for Carsharing by rental offices are built and analyzed in accordance with public transit accessibility. The result indicates 73% of walking as a majority, 3% cycling, and 20% using buses and urban railways to access Carsharing rental offices. The goodness of fit of Carsharing use models reflecting accessibility to buses and railways is verified as 0.818 which proves that public transit accessibility is a significant variable. Therefore, it is verified that installing Carsharing rental offices where public transit transfer is convenient can possibly increase the use demand. Especially, while accessibility to buses is verified as a significant variable out of other public transit means, the accessibility to urban railways is verified as not significant. This suggests that a variety of complementary policies such as transfer discount policy and one-way transfer return policy are necessary in between urban railways and Carsharing in order to promote mutual use demand in accordance with the other public transit means. This study result is yet the basic research on Carsharing, however it is expected to contribute to improvement of transfer demand in between different public transit means.

The purpose of this present study is not only to investigate mutual relationship between general values and clothing behaviors, but to analyize the differences in clothing behaviors in view of socio-economic backgrounds, such as professions, social classes, educational levels, monthly income, etc. For the measurement of the general values, a total of 45 questions were made use of from both part I and part II of 'The study of General Values' jointly developed by Allport-Vernon-Lindzey, while for the measurement of the clothing behaviors were used questions selected from 'The clothing variables Inventory' developed by Creekmore and from those previously used in our country for the same purpose. Data were obtained from 460 Persons and the selected sample was composed of 238 Persons from the upper class and of 222 persons from the lower class. The former class is mainly represented by government officials, doctors, company directors, professors, while the latter by factory workers, clerks, drivers. Analysis of the data in this present study reached its conclusions as follows ; 1. Among the general values valiables, the selected group in this study ranked, theoretical values' first, 'political values' 'econmic values', 'social values', aesthetic values', 'religious values' in that order, and also among the clothing behaviors variables it ranked in the following order ; economy' 'modesty' 'aesthetic' 'conformity' 'status symbol'. 2. A significant relationship between general values and clothing behaviors was found as follows ; there are negative relationships between 'theoretical values' and 'aesthetic', 'status symbol', between 'aesthetic values' and 'conformity', between 'social values' and 'status symbol', between 'political values' and 'conformity', on the one; there are positive relationships between political values' and 'status symbol', between religious values' and 'aesthetic', on the other, 3. In view of profession, it was found that a group of company directors placed the most importance upon 'status symbol', a group of factory workers upon 'economy', a group of drivers upon 'conformity' among the clothing behaviors. In light of social classes, 'economy' was given a high priority by the lower class, and 'status symbol' by the upper class, respectively. Considering educational levels, it was found that the highly educated class placed more emphasis on 'status symbol' and the lower educated class showed their preference to 'economy'. In view of monthly pay, 'conformity' was given a top priority by the middle class, and 'status symbol' by the upper class. 4. As a result of investigating the influence that one's age and marriage effect on clothing behaviors, significant differences were found among the three clothing motivations of 'aesthetic', modesty', 'status symbol'.

This study is to suggest a system to increase workers' job satisfaction by analyzing the impact of conflicts in their families and work places to the satisfaction of work and the effects of personality types affecting job satisfaction. For this study, a questionnaire targeting 450 workers was conducted. As a result of this study, firstly, it was revealed that both conflicts of the family-work place and the work place-family have statistically negative interrelationships and impacts with/on job satisfaction. In terms of sub-fact categories, it is revealed that work itself has more impacts than personal persuasion based on people's value. Secondly, the results of this study concerning the conflicts in a family and the workplace shows the same result with the previous studies. They are formed by mutual interactions of cause and effect. Thirdly, it turned out that differences in Enneagram Personality Types have statistically significant impacts on job satisfaction. The result also shows that thinking-centered personalities and behavior-centered personalities have more impacts on job satisfaction than emotion-centered personalities. Study result indicates that more wide use of a psychology consultation program for workers and their families, EPA(Employee Assistant Program). It also shows that introductions of personality trainning programs and personality coaching programs are required.

Biogeochemical processes in groundwater-stream water mixing zone are recently of great interest because biodegradation and natural attenuation of aquatic contaminants may occur through the processes. The objectives of this study are to investigate the hydrologic and biogeochemical processes at the groundwater-stream water mixing zone through which surface water-driven nitrate may be naturally attenuated, and to examine the effect of the vertical flow exchange flux on biogeochemical processes using correlation analysis. To examine the direction of vertical water flow in the zone, vertical hydraulic gradients were measured at several depths using mini-piezometers. Microbial populations in soil samples of the zone were also analyzed by means of the polymerase chain reaction (PCR) and Cloning methods. In addition, partial correlations among vertical flow exchange, nitrate concentration and microbial activity was investigated to examine their mutual interaction. The results showed the significant interaction among the three parameters, resulting in natural attenuation of nitrate. This study showed an example of the biogeochemical fuction of groundwater-stream water mixing zone, which can be predictable from the examination of the interaction among microbial activities, concentration of contamination and vertical flow exchange flux. temperature show a significant difference in adjacent streambed, Also, the results shows that distribution of temperature was more affected by groundwater direction than intensity of flux.

Recently the web service area is rapidly growing as the next generation IT paradigm because of increase of concern about SOA(Services-Oriented Architecture) and growth of B2B market. Since a service discovery through UDDI(Universal Description, Discovery and Integration) is limited to a functional requirement, it is not considered an effect on frequency of service using and reliability of mutual relation. That is, a quality as nonfunctional aspect of web service is regarded as important factor for a success between consumer and provider. Therefore, the web service selection method with considering the quality is necessary. This paper suggests the agent-based quality broker architecture and selection process which helps to find a service providing the optimum quality that the consumer needs in a position of service consumer. A theory of agent is accepted widely and suitable for proposed system architecture in the circumstance of distributed and heterogeneous environment like web service. In this paper, we considered the QoS and CoS in the evaluation process to solve the problem of existing researches related to the web service selection and used PROMETHEE(Preference Ranking Organization MeTHod for Enrichment Evaluations) as an evaluation method which is most suitable for the web service selection among MCDM approaches. PROMETHEE has advantages that solve the problem that a pair-wise comparison should be performed again when comparative services are added or deleted. This paper suggested a case study with the service composition scenario in order to verify the selection process. In this case study, the decision making problem was described on the basis of evaluated values for qualities from a consumer's point of view and the defined service level.

Purpose - When it comes to first impressions of family restaurants, people basically think of the following factors: cozy, a refreshing space, indoor lighting, atmospheric music, the best-quality service through mutual interactions with employees, birthday events, follow-up customer management, brand image, and many others. Focusing on such family restaurants characteristics, with consumption experience and customer satisfaction determined as mediator variables, this study looks into the selection factors that affect customer loyalty when choosing a family restaurant. Subsequently, the study conducts an empirical analysis of these selection factors with the greatest influence. Research design, data, and methodology - This study analyzed 200 total surveys of family restaurant customers including college students, workers, housewives, and others. The survey was conducted over two weeks in May 2014. For statistical processing, SPSS 21 was used for factor analysis and reliability analysis as well as AMOS for structural equation analysis. In terms of a variable that would influence either consumption experience or customer satisfaction at the restaurants, the study introduced the concept of customer equity. The study designed a model based on a hypothesis developed using the following factors: customer encounter service value, customer convenience value, brand equity, relationship equity, and other factors defined as components of customer equity by Rust et al. (2000) determined as independent variables as well as with customer experience and customer satisfaction set as mediator variables. The hypothesis, after all, assumed that customer loyalty would be positively (+) influenced. Results - The analysis results from the study reported that brand value, customer encounter service value, and relationship value have positive (+) effects on consumption experience and customer satisfaction. However, as for customer convenience value, this turned out not to have a statistically significant influence on consumption experience and customer satisfaction. In regard to a relation between consumption experience and customer satisfaction, the results showed that the former affects the latter, and in terms of intervening variables, both of these appeared to have a positive (+) effect on customer loyalty. Conclusions - This study suggests that family restaurants should look for strategies that focus on how to promote customer relationships. For example, restaurants could try birthday events or discount events to achieve this goal. Since the study ended up realizing relatively low levels of suitability and statistical significance, the path of the study changed. After all, in order to increase suitability and statistical significance, the study had to eliminate factors such as service quality and others and for this reason the study was unable to conduct the analysis as initially planned. In addition, the data samples of the research were mainly gathered from students, which made it hard to say that the analysis was carried out on samples from every different group. Future research should analyze the characteristics of each group of customers for factors affecting customer satisfaction and customer loyalty in the family restaurant chain.

Tidal farm is a multi-arrayed turbine system for utilizing tidal stream energy. For horizontal-axis turbine(HAT) system, it is recommended that each unit has to be deployed far apart in order to avoid hydrodynamic interference among turbines, as proposed by the European Marine Energy Centre(EMEC). But there is no rule for the arrangement of vertical-axis turbine(VAT) yet. Moreover it has been reported that a proper arrangement of adjacent turbines can enhance the overall efficiency even greater than an arrangement without mutual interference effect. This paper suggests the layout of VATs showing the better performances, which turned out to be quite different from HATs' arrangement. Numerical calculations were performed to investigate the performance variation in terms of the rotational direction as well as the distance between turbines. It has been shown that the best combination of rotational direction and distance between turbines can increase its performance higher about 9.2% than that of two independently operated turbines. It is likely that such improvement is due to the increased velocity between adjacent turbines. For diagonally arranged turbines, the maximum normalized mean power coefficient was obtained to be higher about 5.6% than that of two independent turbines. It is expected that the present results can be utilized for conceptual design of tidal farm to harness the tidal stream energy.

As the first class Teaching Artists system is about to be brought to effect, the ability required for Teaching Artists to design educational contents, develop and manage education programs is not much different from that of a museum Educator. This system is necessary for resolving problems in existing Arts and Culture Education, such as overlapping programs and adjusting difficulty levels by age to meet the demand of educatee. It also deals with drawbacks in production-oriented curriculum originating from the preference in some subject. In addition, as progress in science and technology makes rapid changes in digital media and its subculture, increasing need for novel and interdisciplinary curriculum in the field of Arts and Culture Education puts further emphasis on the importance of this system. In this study, we focus on clarifying the significance of Educator as a professional and proposing curriculum for the system, trying to avoid restricting our discussion to current Arts Instructor Supporting Project which are merely aimed at supporting children and adolescents to grow up to enjoy culture and arts. Capacity for designing curriculum for culture and arts, the kernel of qualification for the first class Teaching Artists, requires a variety of comprehensive expertise and qualification such as doing preliminary research on contents related to animation, curating, determining potential of educational contents, organizing educational contents for appropriate educatee, understanding esthetic property and its role in education, and appreciating and enjoying cultural contents. Therefore, Teaching Artists plays roles not only in developing and running educational programs but also in supporting and cooperating with culture and arts institutions, designing and managing creative programs, combining and communicating with different social groups, and emphasizing mutual interchange in culture.
