  • In the analysis of product reliability, the fault tree is widely used since it shows the interrelations of the faults that lead to the product fault. A top-down approach based on experts’ experience is commonly used in the fault tree construction and the trees often take different forms depending on the intent of the analyst. In this work it is studied how to construct fault trees with the utilization of function trees obtained from analyzing the functions and sub-functions of products in order to suggest a generic way of fault tree construction. The function tree of a product is obtained by analyzing basic functions comprising the product main function in a bottom-up approach so that it enables to construct an objective fault tree. The fault tree for a scroll compressor is shown as an example.

  • The purpose of this study is to compare the differences of clothing behavior by the level of self-monitoring under given social situations. The result of this study is drown from the analysis of the survey, gathered from the 522 female students of universities reside in Seoul, by using the method of convenience sampling. The statistical methods used to test the data were MANOVA and chi-square test. The results of this study can be summarized s follows; first, as a result of analyzing the differences of situational self-image pursuits among situations depending individual's self-monitoring levels, it was found that the pursuits changes among situations regardless of the self-monitoring levels. Thus, this hypothesis could not be verified. Second, as a result of analyzing the changes of priority of clothing selection factors among situations depending on individual's self-monitoring levels, it was found that the priority factors changed among situations regardless of the self-monitoring levels.

  • This study aims at determining what affects lighting environment of a kitchen in a Japanese restaurant in a hotel and at analyzing. cooks' perception during cooking and appropriate lighting they consider to be important in each working area. For this purpose, 196 cooks working in Japanese restaurants in first-class hotels participated in a survey. After analyzing the results, cooks attach importance to illumination during cooking, and the more inappropriate luminosity is in each working area, the lower appropriateness of luminosity recognized by cooks is. And there is strong correlation between lighting environment items and illumination in each working area. The results suggest that cooks working in a Japanese restaurant in a hotel should be provided with good lighting environment appropriate for each working area. On this ground, it is expected that cooks will see their health and productivity improving.

  • The market size of Internet portals has been continuously expanded and also competition has been fierce. For the business success of Internet portals, it is necessary to repeatedly perform a renewal project which improves their services, reflecting more improved or changed strategies. Accordingly, this paper proposes an analysis methodology for performing the renewal project more systematically and effectively. The methodology consists of four phases : establishing improved strategies, analyzing customers, deriving service alternatives, and determining services. The methodology places an emphasis on reflecting effectively customers' standpoints (i.e. customers' needs) and service providers' standpoints (i.e. business strategy) upon service improvement. Furthermore, the methodology includes a specific technique for analyzing the feasibility of services. To demonstrate the practical usefulness of the methodology, a real-life case is illustrated.

  • Alliances, collaborations and partnerships are essential practices in today's business. The purpose of this study was to understand the trends in retail alliances by analyzing the patterns of alliances in the Korean retail market. Retail alliance cases were collected from the published news article database in a major internet portal. A total of 1,061 retail alliance cases for the first decade of the 2000s were categorized into the alliances: 1) within the same retail format and 2) across different formats within the retail industry; and 3) with service industries and 4) with manufacturing industries outside the retail industry. The study described the patterns on the characteristics of participating retailers and partners, industries involved, and alliance types for each of the four categories.

  • This study was mainly done by factors analyzing to find out the structure and the dimension of the results of a previous study; analyzing the school and hospital dietitians'human attributes needed for successful job performance(Song 1998). The results were as follows: 1) Through factor analysis, the 12 knowledge items were categorized into 4 groups ; ‘basic knowledge of food and nutrition’, ‘knowledge of clinical nutrition and diet therapy’, ‘knowledge of medial science’, and ‘knowledge from experience and common sense’. These 4 knowledge factors were more frequently used and importantly recognized by hospital dietians compared with school dietitians. 2) The 38 skill and ability items were categorized into 7 groups ; ‘ability of program development and research’, ‘ability of counseling and nutrition education’, ‘ability of production control and facility management’, ‘ability to use computer’, ‘ability to cooperate with others’, ‘ability to manage consignment marketing’, and ‘ability of managing situations and informations’. Different skills and abilities were required for each group. 3) The 11 personality items were categorized as 3 groups ; ‘respoinsibility and sincerity’, ‘positive personality’, and ‘affirmative and inquisitive personality’.

  • This paper describes a theoretical model developed for analyzing the heat transfer of automotive cooling systems. From the model, heat transfer rate of automotive cooling systems can be predicted, providing useful information at the early stages of the design and development. The aim of the study is to develop a simulation program for automotive cooling system analysis and a performance analysis program for analyzing heat exchanger. Heat release rate from combustion gas to coolant through cylinder wall in engine cylinder was analyzed by using a two zone combustion model. This paper studied how cooling condition would affect engine heat release rate and measured temperature distribution of coolant in water jacket.
