When humans make decisions, they differentiate classifications of individual attribute variables that affect the decisions according to the importance and pattern of each attribute variables. The present study examines the practicality of the proposed Code Arrangement-Based Reasoning(CABR), which resembles the human's way of reasoning. To this end, we developed a CABR technique that classifies each attribute variable affecting significant impacts on the target variable into a cluster and assigns a code to the cluster. For verifying the proposed technique, both case-based reasoning and CABR were used for the customer continuance judgment problem of an automobile insurance company. Results indicated that the performance of CABR is close to the one of the case-based reasoning. The CABR also shows the possibility of using bio-informatics techniques for organizational data analysis in the future.

Online communities are an important source of electronic word-of-mouth (e-WOM). However, few studies have examined the use of such messages within the Middle Eastern context. This study focuses on Saudi women as members of an online beauty forum. Previous work suggested a mediating effect of gender, with women being more likely to trust word-of-mouth and follow it up with a purchase. A conceptual model with a theoretical underpinning from existing contributions in literature provides the basis of a coding framework for the message characteristics that influence members' e-WOM adoption. A total of 310 threads and 2200 messages coded into 5725 units were content analyzed to demonstrate cases where e-WOM was adopted and indicate further continuance intention with members returning to the forum. A new category of 'community bonding' was created from the content analysis given the prevalence of emotional aspects in messages. Emotion expressed in messages, often expressed in religious terms, is as influential and important as the cognitive aspects of community bonding.

This study proposed an expanded technology acceptance model (TAM) incorporating perceived fee (PFE) and perceived enjoyment into the original TAM We examined that the extended TAM provides supplementary information about behavior intentions (BI) toward mobile data services (MDS). This study also investigated some significant differences in the relative influence of the determinants of BI toward MDS depending on experience. The extended TAM was empirically evaluated by using survey data collected from 149 inexperienced users and 393 experienced users. The findings indicated that PFE is the strongest determinant of BI toward MDS, and the antecedents leading to users' BI vary over time. The results may provide further insights into MDS practitioners and marketing managers.

People tend to resist changing their software even alternatives are better then the current one. This study examines the resistance to change in the use of software from the switching costs perspective based on status quo bias theory. For this study, we select Web Browsers as software. Based on the classification of switching costs into three groups (psychological, procedural, and loss), this study identifies six types of switching costs (uncertainty, commitment, learning, setup, lost performance, and sunk costs). This study tests the effects of six switching costs on user resistance to change based on the survey of 204 web browser users. The results indicate that lost performance costs and emotional costs have significant effects on user resistance to change. This research contributes towards understanding of switching costs and the effects on user resistance to change. This study also offers suggestions to software vendors for retaining their users and to organizations for managing user resistance in switching and adopting software.

The objective of this study is to analyze the properness, effectiveness and sustainability on the large-scale environment-friendly agricultural districts (LEAD). For this, we survey 11 public officers who manage the LEAD. Most of them aware necessities of LEAD project. They have a higher satisfaction and think that the project affect ripple effect and contribution on environment-friendly agriculture. Main performance expected of the LEAD project is a spread of natural circulation agriculture in connection with cultivation and stockbreeding. For continuance of environment-friendly agriculture after the project, it is necessary to find markets of products. Also policy making related with environment-friendly agricultural technique is required. The results of this study show that the LEAD project need a modification based on field and change of agricultural issues.

PID 제어기는 산업자동화 설비에 널리 쓰이고 있다. 하지만 시스템 특성이 간헐 또는 연속적으로 변화할 때에 정밀제어를 위한 새로운 매개변수 결정이 쉽지 않다. 이를 해결하기 위한 방법으로 본 논문에서는 PID 제어기와 같은 기능을 갖는 학습이득조절기를 제안하였다. 시스템의 적절한 학습이득은 델타 학습규칙에 의해서 결정된다. 제안된 학습이득 조절기의 기능은 직류 전동기의 모의실험에 의해 확인하였다.

Since IMF system was introduced once, downsizing has been usual phenomenon in business sphere. Downsizing influences the unemployed, and also the survivors such as in job stress, communication bias, lower organizational commitment and so on. This paper reviewed the relationship between organizational commitment and service quality, and the moderating effect of sex in hotel. Based on the responses from 494 hotel employees, the results of multiple regressional analysis showed that affective OC and normative OC have affirmative effects on service quality. The results of moderating analysis showed that continuance OC has an affirmative interactive-effect on responsiveness, assurance, and empathy with gender, and affective OC an negative interactive-effect on assurance.

This thesis has purpose of explaining that light is not only appreciated but also physically percepted in contemporary space design and examining effects of space experience through the physical perception. In keeping with such developments, light has been perceived as the object of another architectural tool in modern space design and has provided men with new experience by providing space image and function different from previous ones. With the expansion of the area of light, light has changed a space that is not a simple architectural factor into the essential concept that gives the architectural space image ! by combining it with architectural space, structure, form and materials throughout the whole process from the beginning to the completion. Through phenomenological approach, light is percepted and experienced by body movement, intervention of senses and memories, and passing of time. The percepted and experienced light brings increase of mutual understanding in space, activation and continuance of user's sensation, recreational experience by event occurrence and space experience effect thorough information from media.

This study is focused on the indeterminacy of the contemporary social structure based on the philosophical concept of relationship. The purpose of this study is to present the index of the space planning that the contemporary society demands through analysis of a characteristics of the indeterminate program. As the result, we got a characteristic and a design method of the following indeterminate programs. (1)The characteristic of the interior space programs are in such cases as combined, the continuance, the pile, the juxtaposition, mixing and interference etc. (2) The characteristics of space planning are multiple changes of the space occupation, various sight experiences, folding structure, expansion of flow space, the insertion of a between spates etc. (3) The characteristic of space design expression is addition of various functions tv unification of a structural element and an element of furniture.

To date Korean electronic industry has held a position of the first rank both in productions and exports among the nation's industries. However, it is gradually losing its competitive foundation in the world market owing both to the weakening in price competition by least developed among developing countries(LDDC) and to the lack in technological competition with industrially advanced countries. Specifically it is worried about an industrial subordination to industrially advanced countries owing to an evasion of components supply, control of amount of materials, and the evasion of kernel technology transfer etc. As the condition has developed, both the government and the electronic industry in July of this year came to jointly establish a research and development center for electronic components for the purpose of rehabilitating the electronic industry and accordingly strengthen the export industry which has been and continuance to be vital to our nation.
