This study identified fashion consumers disposal behavior and analyzed the effects of consumers pursuing values in disposal, environmental awareness, and sustainable fashion consumption attitudes in regards to fashion disposal behavior. A survey questionnaire was developed and data were obtained from 460 consumers in their 20's to 50's in Korea who had experienced fashion disposal behaviors during last 12 months. As a result, there were four different fashion disposal behaviors such as economical, practical, and social disposal as well as hoarding behaviors. Consumers pursuing values in disposal affected fashion disposal behavior. Practical and economical values had positively impacted economical disposal and hoarding behaviors. While hedonic value had a negative impact on economical disposal behavior, it had a positive impact on social disposal behavior. Also, environmental-social values had positively impacted practical and social disposal behaviors. Fashion-related environmental knowledge had positively impacted economical and practical disposal behaviors and PCE affected social disposal behavior, while environmental concerns had a negative impact on economical disposal behavior. Consumers attitude toward used-fashion items, fashion recycling, and fashion innovativeness affected all of fashion disposal behaviors. Although hoarding behavior has been an under researched area, the finding implied that hoarding behavior was affected by consumer's pursuing value in disposal and sustainable consumption attitude. Also, environmental-social values and attitudes toward used-fashion items would induce practical disposal behavior such as reuse by alteration or reform. Consumers economical and hedonic values can promote donations or exchange/resale of unwanted fashion items, which can lead to sustainable consumption.

This study verified the motivation to use Tiktok for Chinese teenagers. This paper investigated the influence of adolescents'use motivation on use satisfaction and continuous use intention. In addition, this study was to grasp the relationship between use motivation and sustained use intention as a mediating effect of use satisfaction. The survey was conducted online and offline, 315 adolescents were selected for analysis. For the data, factor analysis, multiple regression analysis, and effect analysis of parameters were conducted using the SPSS 25 program. As a result of the study, information/entertainment pursuit, communication, and self-expression were derived as motivation for use. Among these motivations, information/enterprise pursuit and communication were found to have a significant effect on use satisfaction and continued use intention. In addition, it was confirmed that use satisfaction has a mediating effect on intention to use continuously. But it is found that the self-expression factor handled as reuse intention have no significant influence on the use satisfaction and continuous use intention of Tiktok.

Just as noted in some studies related to U-learning based on the ubiquitous technology, it is required to reflect both factors of the environments and contexts of learners on the teaching and learning strategy. For this, the current paper suggests an inquiry learning method and a mobile learning support device for the inquiry learning. Since the inquiry learning is operating on the basis of the contents that learners themselves experience in the fields, it naturally leads them to position in the learning environments and contexts. In this study some curricula are adopted and transformed for the inquiry learning, and the developed mobile device for the learning has a guide function, so that learners might follow the inquiry learning process. In addition, it is possible to reuse the acquired learning data by storing them on a remote learning sever, which may support the inquiry learning of students. These system and device are applied in the teaching sites of schools and, consequently, it is found that in regard with the learning interest and academic performance of students there is an advanced result, being statistically significant.

Rapid social change affects residential environments and this in turn creates new stimuli to which people have to adapt. These stimuli have been seen to increase stress levels. Therefore, dwellers in these environments try to reduce stress through various methods. The purpose of this paper is to: 1) identify the general trends of coping styles about residential environmental stress, 2) analyze the differences in socio-demographic characteristics and how the physical characteristics of buildings affect stress, find out how personal backgrounds affect stress levels and the ability to get rid of environmental-related stress. The subjects in this study consisted of people living in multi-family housing in Gwangju. The city is divided into 5 districts and used quota sampling. 324 housewives were surveyed from the households by self-administered questionnaires. The survey was conducted in December, 2006, after the questionnaire was revised based on the results of preliminary survey. After all the questionnaires were collected, the data was coded and analyzed using the SPSS 12.0 program. This study confirmed that the manner in which those in multi-family housing coped with stress. Especially, we need a policy which seriously considers residents who are of low social-economic standing. As well as being exposed to residential environmental stress, they also have no means to deal with it. The age of a building had a strong impact on coping styles about residential environmental stress. We have to make special studies about the adaptive reuse of buildings for the reduction of residential environmental stress and to greatly improve coping styles. In conclusion, it emphasized the importance of education, information, and economic aid. Reasonable housing management would surely lead to a rise in residential satisfaction and the promotion of residential welfare.

Today, Digital Right Management (DRM) is used to protect copyrights of digital contents from illegal reproduction and redistribution. Unfortunately, current DRM systems are causing user's discomfort because of lack of mutual compatibility. In order to overcome this drawback, technologies for interoperability of heterogeneous DRM systems are developing. In this paper, we study the protection profile for conversion technologies of heterogeneous DRM systems, using the Common Criteria. Especially, this paper is written by reuse of the existing protection profile. Therefore, performance analysis reveals that efficiency of time and cost is significantly improved. This protection profile can be used by contents provider and administrator who manage user's copyrights to reference data for copyright protection.

With the recent establishment of a ubiquitous environment and the paradigm shift to a smart society, the use of mobile devices, such as smart phones and tablet PCs, has become widespread. Thus, the trend is gradually shifting from using Web-based Instant Messenger to using Mobile-based Instant Messenger. Mobile Instant Messenger refers to a service that allows instant messaging as well as data sending and receiving between individuals with exclusive application programs(mobile Apps), which can be used in portable devices-such as smart phones-with wireless Internet access. Korea's portal sites, telecommunication companies, and even big companies have all rushed into the MIM market to join the competition. The reason so many companies are showing interest in the MIM business is because it is rising as a core platform to substitute portal sites in the mobile society, and MIM is perceived as the best means to attract and secure users. The intention to reuse or use continually was considered an important factor in maintaining a dominant position amidst such fierce competition, and consequently, most research thus far has reflected such thought. However, the frequent or long-term use of a system alone cannot indicate the definite success of the system, nor guarantee its dominant position in the market. On the contrary, MIM dependence, which goes beyond simple repetitive use and indicates a state where users actually or emotionally depend on a specific system, can better explain the user action. However, not much research has been conducted on dependence. The research results showed that lively message, concise message, message responsiveness, and social belonging significantly affected perceived usefulness. Message responsiveness, Link, and social belonging significantly affected flow. Flow significantly affected MIM dependence, and perceived usefulness did not affect MIM dependence. This study has proven that lively message, concise message, message responsiveness, Link, social belonging and perceived usefulness are important antecedents and mediating factors of MIM dependence. Moreover, this study is significant in that it explains the overall process of MIM dependence, and expands on the variety and scope of research that can be applied to MIM-related studies.

The testing time and cost of developed software can be reduced by automation of the whole or part of testing process. Since the testing automation tools to be used currently have been developed without their interoperability, test case information such as test procedures, test data, and expectation of test results generated at the stage of test execution cannot be shared and reused in other testing automation tools, In order to reduce testing time and cost, in this thesis, we have proposed a software testing automation framework which makes it possible to share and reuse the test case information generated in testing process. To prove the availability and effectiveness of proposed testing automation framework, three testing automation tools that are available in current market were experimented by the test scenario. As a result of experiment, the testing time and cost could be reduced by sharing and reusing the test case information in software testing automation framework.

Problems and improvemental measures for the historical inquiry of TV drama costumes and for the reproduction of them were investigated. For this study, the MBC historical drama 'The way of the Great King' started on march 24 in 1998 and ended on september 26 in 1998 was selected as the subject. The reasons why the drama was selected are as follows. First, the historical background was the time of King Young ＆ drama introduced various kinds of costumes Joungjo, which is the starting era of traditional costumes peculiar to Korea. Second, the based on the historical inquiry of that time. There is a limitation in the process of historical inquiry about the costumes of that time because we don't have enough research data such as relics, remains, references, literary works, pictures, etc. Although, in some cases, exact historical inquiry about the costumes were made, they could not be reproduced in the original forms due to several reasons: the absence of the materials of that time, structural changes including length and size for convenience of action, alterations of the manufacturing method for the reuse, addition of the gorgeous and various olors for the enhancement of image quality, variations in colors according to the actor's character, modulations of the structures and colors by the producer's intention, and the restraints in time and money for manufacturing. In view of these situations, it seems to be difficult for us to settle the problems occurring between the historical inquiry about the traditional costumes and the reproduction of them in drama. However, the costumes presented in historical drama have the meanings to provide informations of that time with TV audience. Therefore I think that it is necessary to narrow the gap between the historical inquiry of TV drama costumes and for the reproduction of hem, First, It should be restrained that each broadcasting stations show the costumes under the similar situations of the same age in different ways. Second, We need to unify the inquiry systems concerning historical drama costumes, In addition to this, it is also necessary for broadcasting stations to establish internet sites of traditional costumes for communication.

These papers propose an evolutionary algorithm for re-using output of waste fuel of light water reactor system in nuclear power plants. Evolutionary algorithm is useful for optimization of the large space problem. The wastes contain several re-useable elements, and they should be carefully selected and blended to satisfy requirements as input material to the heavy water nuclear reactor system. This problem belongs to a NP-hard like the 0/1 Knapsack problem. Two evolutionary strategies are used as a, pp.oximation algorithms in the highly constrained combinatorial optimization problem. One is the traditional strategy, using random operator with evaluation function, and the other is heuristic based search that uses the vector operator reducing between goal and current status. We also show the method, which performs the feasible teat and solution evaluation by using the vectorized data in problem. Finally, We compare the simulation results of using random operator and vector operator for such combinatorial optimization problems.
