  • The purpose of this study is to investigate the characteristics of members and communities that have significant influence in the online fashion community through their word-of-mouth activities. In order to identify the influence and the diffusion of word-of-mouth in fashion community, the study selected one online fashion community. Then, the study sorted the online posts and comments made on fashion information and put them into the matrix form to perform social network analysis. The result of the analysis is as follows: First, the fashion community network used in the study has many active members that relay information very quickly. Average time for information diffusion is very short, taking only one or two days in most cases. Second, the influence of word-of-mouth is led by key information produced from only a few members. The number of influential members account for less than 20% of the total number of community members, which indicate high level of degree centrality. The diffusion of word-of-mouth is led by even fewer members, which represent high level of betweenness centrality, compared to the case of degree centrality. Third, component characteristic shares similar information with about 70% of all members being linked to maximize information influence and diffusion. Fourth, a node with high degree centrality and betweenness centrality shares similar interests, presenting strain effect to particular information. Specially, members with high betweenness centrality show similar interests with members of high degree centrality. The members with high betweenness centrality also help expansion of related information by actively commenting on posts. The result of this research emphasizes the necessity of creation and management of network to efficiently convey fashion information by identifying key members with high level of information influence and diffusion to enhance the outcome of online word-of-mouth.

  • This study has been performed to explore process of forming low cost small site housing communities and residential lives of the young elderly around small cities along rural counties of America and Canada, and suggest future implications for Korea. In this study, five low cost small housing zones such as cottage and mobile home parks in non-metropolitan counties of California and Ontario State such as Weed, Paradise, Sun City,, Wellington on the Lake, and Trenton were visited and the elderly residents and service experts were interviewed. The senior concentrating housing clusters were formed primarily from influx of both metropolitan and rural residents for the purpose of seeking warmful localities, traffic connections, and business purposes in theme focused production areas. On the other hand, residential lives in the zones are occasionally negatively influenced by unbalanced concentrations of elderly facilities such as nursing stations and funeral homes. For the future of Korean rural elderly policies, suggestions are made as follows: first, integrated forms of urban and rural township need to be settled as attracting places for early retiring people who seek low cost pastoral oriented but culturally activated environment. Second, a model town of mobile housing structures needs to be initiated as a measure of evaluating adaptation process of those movers. Third, a cooperation system among governmental ministries needs to be formed in order to integrate a long term master plan of establishing traditional rural town of independent housing districts. fourth, productive and active lifestyles need to be maintained for government lead retirement rural villages by limiting expansion of nursing related facilities around the independent areas. Fifth, visiting welfare service programs and volunteer groups need to be further developed for the housing area especially in winter time, when social integration and emotional comforts are extremely limited.

  • This study intends to reconsider pleat, which was undermined as something too simple to express the details for women's costume, by focusing on the aesthetic value of plea in men's costumes in the west before the 20th century. Furthermore, based on the aesthetic value of the pleat, diverse studies on contemporary men's costumes shall help to attempt to set up a basis for the new mode of men's costume. The pleat, a component in the costume since the ancient times, had unique characteristics including functionality, a sense of volume, directing effect that is caused by line repetitions and formativeness that results through elasticity. First, the aesthetics of the pleat before the 20th century shows rhythmic sense through the repetition of the pleat line as shown in the drape type costume, and it also shows a sense of volume as the pleat is moved along the motion of the body. Second, it shows functionality as the expansion of space moves in accordance with the motion of body sets up an internal space of the costume that facilitates body motion. Third, the pleat extends two dimension space into three dimension space using its elasticity. It exaggerates specific parts of the costume while ignoring body shape in order to symbolize status and authority of men. Fourth, it unifies the costume by wrapping the body by using quadrangle cloths with drapers, and expanding the silhouette with the pleat artificially to conceal the physical character and personality of the wearer. The physical character of the wearer disappears into the space made by the pleat. The pleat reveals the voluptuous beauty within.

  • Occupying the center of architecture, design, painting and culture, minimalism is aesthetics of essence that reflects modern age but transcends age at the same time. Pursuing minimalist trend like this and covering the range of furniture, interior and architecture, total designer Antonio Citterio is developing minimalist designs of his own. Called one of the 3 greatest furniture designers in the world today, he leads the trend and enjoys high reputation as a world-renowned interior designer and architect. Therefore, the purpose of this study is to analyze and integrate minimalist descriptive characteristics which appeared in interior space of Citterio who pursues minimalist design. As a study method, this study reorganized minimalism from methodological perspective, drew out expressive characteristics of minimalist interior spaces unique to Citterio based on background and influence of Citterio's design and, centering on this frame of analysis, analyzed and integrated interior spaces he designed. The results of this study are as follows; first, in order to overcome problems that can become monotonous in a minimalist space, Citterio provides spatial experiences to feel visual and spatial variations using the ramp and bridge. Second, he created various senses of space with visual and spatial expansion using transparency in the walls made of glass. Third, with linear expressions, he designed modern spaces with beauty of proportion and balance through contrast and emphasis. Fourth, he made constructive expression through exposure of structures or stairs in the space. Fifth, he created sophisticated atmosphere with contrast between natural and artificial materials and emphasis of material properties. Sixth, his design also shows the characteristic of using furniture as the role of adjusting overall atmosphere of interior space, not as separated parts from it. The author hopes that above results of this study will provide new implications for the development of domestic interior design.

  • School lunch programs at middle schools have increased in quantity. However, the quality of them is in fact not enough to reach the satisfactory standard, especially in the aspect of environment of school meals. It is true that there seems to be little attention to the environment. In this study, degree of satisfaction about school lunch program was surveyed for students in one middle school. Focus of survey was sanitary condition about the dining room and classroom where they have lunch. First, in order to investigate the degree of satisfaction about their dining place, questionnaire was sent out to the students at one middle school in Seoul. Questionnaire was made with reference to previous research. Second, for the study on environmental sanitation, dropping bacteria (general bacteria) is measured in three parts of dining place (entrance, serving table, dining table). Petriplate film was exposed to the responsible places for 15 minutes and then cultivated at the temperature of $32^{\circ}C$ for 48 hours before counting the number of bacteria formed. For the statistical analysis, SPSS 12.0 was used. The results of the study show that students had more satisfaction in dining room service than in classroom service. Important factors for the meal program such as "taste of food", "amount of food per student", "state of keeping warm", "appearance of food", "diversity of menu", and "kindliness of feeding staff" had more points in dining room than in classroom. For the environmental and sanitary aspect, the result of dropping bacteria (general bacteria) in dining room and classroom showed that table (5.00) and fooddistribution corner (8.67) of dining room were cleaner than those of classroom (P < 0.05). Making a good environment for school feeding will have a positive effect on the improvement of satisfaction and sanitation of school feeding. There should be expansion of dining room service for the students.

  • Th~ss tud is to recommend a suggestion to adapt and expand the class 200 Religon for Korean libraries using DDC. The grst art of it investigates the development and general problem of the options in 200 and leads to the conclusion t k t it is somewhat undesirable to use the options in the libraries of the nations m y religions are predominant, as in Korea. The second part of it recommends a su gestion. The major characteristic of it is that it not onl follows the basic systems and order of the DDC but a k suggests the plan that emphasizes the Budhsm andother religions of brea, Ouna, and Japan, for Korean libraries. It contracts the Christianity of 22@280 in oripl DDC lnto only one division 220, and rearran es the divisions 230-270 for the BudNusm and other religions oi the world so that various religons can be inc\ulcorneruded in the divisions.

  • Analyzing the effects of information technology(IT) in the life insurance Industry is important in establishing the direction for future information technology investment. In this research, the cost-elasticity of IT capital stock was measured by the SUR technique, using the second-order translog cost function, which was drawn out by a Taylor expansion of the multi-product joint cost function. Analysis was made based on data from 1991 to 2003 collected from 33 life insurance firms. The results show that although the effects of information technology investment vary according to individual life insurance firms, half of the life insurance firms surveyed reduced their costs by investing in information technology. The research also revealed that although large life insurance firms reduced their costs by investing in information technology medium & small life insurance firms and foreign ,life insurance firms increase their costs. Additionally, although both information capital and information labor increase as the information budget increases, the increase in information capital is larger than one in information labor. Because the price of information capital is decreased rapidly more than one of information-related labor.

  • The interface design for most present query-base model of OPAC systems does not include the function to implement an iterative feedback process till the user arrives at satisfied search results through the interaction with the system. Also, the interface doesn't provide the help function for a user to select pertinent search terms. To formulate a query at the present OPAC system, a user should learn a set of syntax different from system to system. All of above mentioned things make an end-user feel difficult to utilize an OPAC system effectively. This experimental system is attempted to alleviate a few limitations of the present OPAC system by a n.0, pplying the direct-manipulation technique as well as the feedback principle. First, this system makes it unnecessary for a user to learn some syntax for query formulation by providing option buttons for access points. Second, this system makes it possible for a user to decide whether each displayed record is relevant or not, and for keywords included in the relevant records to be automatically stored in order to be used for later feedback. Third, in this system, the keywords stored in [sayongja yongeu bogyanham] can be deleted if unnecessary or can selected as search terms for a query expansion as well as a query modification. Fourth, in this system, after inputting the original query, the feedback process can be proceed without coming back to the previous search step until a user becomes satisfied with the search results. In conclusion, the searching behaviors of heterogeneous users should be continuously observed, analysed, and studied, the findings of which should be integrated into the design for the interface of the OPAC system.

  • All machines deteriorate in performance over time. The phenomenon that causes such performance degradation is called deterioration. Due to the deterioration, the process mean of the machine shifts, process variance increases due to the expansion of separate interval, and the failure rate of the machine increases. The maintenance model is a matter of determining the timing of preventive maintenance that minimizes the total cost per wear between the relation to the increasing production cost and the decreasing maintenance cost. The essential requirement of this model is that the preventive maintenance cost is less than the failure maintenance cost. In the process mean shift model, determining the resetting timing due to increasing production costs is the same as the maintenance model. In determining the timing of machine adjustments, there are two differences between the models. First, the process mean shift model excludes failure from the model. This model is limited to the period during the operation of the machine. Second, in the maintenance model, the production cost is set as a general function of the operating time. But in the process mean shift model, the production cost is set as a probability functions associated with the product. In the production system, the maintenance cost of the equipment and the production cost due to the non-confirming items and the quality loss cost are always occurring simultaneously. So it is reasonable that the failure and process mean shift should be dealt with at the same time in determining the maintenance time. This study proposes a model that integrates both of them. In order to reflect the actual production system more accurately, this integrated model includes the items of process variance function and the loss function according to wear level.
