In the external inspection and packaging stages of products used in the semiconductor manufacturing process, there is a problem in which particles are adsorbed to the product itself or a carrying tool due to electrostatic discharge. This study presents a methodology that can improve the problem of adsorption of particles to a product by using a practical TRIZ technique. By applying the proposed practical TRIZ-based methodology, the problem was defined, and contradictions caused by product waiting time were derived. Among the derived contradictions, physical contradictions were set and the concept of 'space separation' was applied to derive solutions such as 'installation of Ionizer' and 'improvement of the layout of the workroom'. As a result of the experiment by applying 'Ionizer Installation' and 'Workroom Layout Improvement' derived through the application of practical TRIZ, it was confirmed that the particle adsorption problem that occurs during the waiting time of the product can be solved.Through this study, it is expected that workers, facility engineers, and technical engineers working at manufacturing processes will be able to effectively solve the problems they face through creative thinking and change of ideas by using practical TRIZ techniques, and contribute to innovative technology development and productivity improvement.

Recently, hospital patients experience anxiety, confusion, and stress about wayfinding as the spacial layout and treatment circulatory system of hospitals have become complicated due to their oversized and complex structure. As part of finding a solution to the problem, this study seeks to examine what are the essential elements of the wayfinding planning of O.P.D. in general hospitals, to develop the model of wayfinding, and to suggest the methods of improving the wayfinding system. The research methods of this study adopted were literature review in wayfinding cognition, plan analysis of ten general hospitals, space analysis of these hospitals through space syntax, analysis of the system of visual-perceptual information through a field study, and analysis of surveys and follow-up surveys conducted to support the results. Based on these results, the proposals for finding decision points, providing the information, and developing a model planning are listed as follows. 1) The comprehensive understanding of O.P.D. spacial layout and the visual-perceptual information system is necessary to find the essential elements of wayfinding. 2) The decision points are found through the full understanding of spacial functions, circulation systems, and facility configuration, considering the spacial layout, the bound of the visual-perceptual information system, and the circulatory system. Furthermore, the information decision points could be confined by space syntax. 3) The checklist and color compound & color codes, developed through the planning of signage system and color system could be applied to the methods of providing the information. 4) The planning of wayfinding system according to the whole process of practices for outpatients was mentioned above. The system of visual-perceptual information developed through the process of this study should be integrated in the spacial layout of the whole O.P.D.

This research is concerned with environment problems related to Munhwa-Maul where Korean government are financially much supporting in developing housing sites and constructing houses. The purposes of this research are to find out the problems and to present the practical guidelines in order to improve an environmental quality of Munhwa-Maul in which will be under construction in the near future. The method for finding out the problems are based upon the most atisfaction and dissatisfaction of residents with opened interview. Both Mueur Munhwa-Maul and Umo Munhwa-Maul are considered for this research because Mueur Munhwa-Maul is characterized with a modern village where is located far from the city while Uo Munhwa-Maul, near the city. Also, these Munhwa-Mauls have been firstly constructed. The interview participants are 34 persons in all. They are confined to Mueur Munhwa-Maul and Umo Munhwa Maul that have been firstly constructed in Kyeongook. According to the interviews, each 60% of both Mueur Munhwa-Maul interview participants and Umo Munhwa-Maul ones have shown the their most positive satisfaction in a new housing and facility. It can be seen from that these figures that housing environment including facility of both Munhwa-Mauls is surely improved and successful. On the other hand, 43.8% of Mueur Munhwa-Maul participants and 14% of Umo Munhwa-Maul ones have particularly shown the most negative satisfaction in a size of housing lot. Also, 15.6% of Mueur Munhwa-Maul interview participant and 44% of Umo Munhwa-Maul ones have stated the most dissatisfaction in a traffic convenience. The reasons showing these differences are likely that 90% of Mueur Munhwa-Maul residents are farmer while 85% of Umo Munhwa-Maul ones are not farmer. With this results the purpose of munhwa-Maul project that government has been supporting and the reality of Umo Munhwa-Maul could be never coincident. Therefore, it can be inferred that housing layout should be reconsiderd to be appropriate for agriculture and that the government should carefully consider the contributions of new housing lot to real farmers. In addition, we can say that Munhwa-Maul project should be firstly accomplished in the district far from the city rather than near the city.

Resort Hotel Rate System was first introduced as an official guideline after Tourism Promotion Act, which enables the secretary of transportation to rate resort hotel by its facility and accommodation, was enacted on January 18, 1971. And the system was modified time to time to what we currently have after numerous revisions. However, the system has made a slow progress compare to the other countries system and have shown many potential problems that need to be improved. There is a problem that it is not even clear whether the act is as effective to apply it to rate any resort hotel in reality. The hotel rate system was first introduced in 1970's and changed ever since, and it also changed the private organizations to audit the decision. However, unlike the hotels in other countries, our hotel rating system is not focus on the customer's service and informations. It focus on the hotel's quality so that cause the problem whether the hotel is for customer or not In other different countries, they have some specific standard for evaluation of customer service based on customers' reference or needs. However, there is no evaluation part concerning on customer service in Korea. Also, even the hotel rating system is not based on the hotel waitress or waiter's service part. It means the system is almost focus on the hotel's qualities. Therefore, customer who needs hotel service, can not trust whether they can choose the hotels which gives the right informations and good quality services. Although hotel's physical layout is important, the service part is also important for evaluating the hotel entirely. There are a lot of things to develop and to be changed in order to develop tourism industry in the process of decision about Hotel's level in Korea Thus, this research will summarize some problems which are revised through the former research of hotel's level. And it will compare the system of hotel's level between Korea and developed countries in hotel industry Additionally, I will show current tourism industry in Korea. Finally, I suggest the improvement proposal for the level system of hotel in Korea and process of this system in the future.

Urban campus, one of the main urban facilities, is the representative place that is struggling with 'gridlock'. Due to privatization of space among different departments and space shortages, gridlock has been occurring as a result. The urban campus trying to solve this problem by changing the quality of space, especially the structure of the shared space, which is expected to be the solution to the grid lock problem. The main purpose of this study is to investigate the structural change in the university's shared space based on paradigm transition. The theoretical consideration is to analyze the spatial characteristics of university shared space that appear at different stages through a new perspective that compares the gridlock phenomenon and the shared paradigm. The framework of the analysis of the shared space, which has recently been restructured, is classified into the spatial characteristics of collaborative space, the creative space, and the common/complex space. In addition, these spatial characteristics are again analyzed through the division of legislative facility classification, management governance subject, area, building location and layout, exposure to the outside as well as the analysis of student and staff entry and exit, sharing structure of site and space, and the classification of program characteristics. The results are as follows: The restructured space is systemized so that the management governance of each space would be connected to each other to share information and space. Furthermore, the spatial boundary between colleges or between campus spaces are not only physically, but categorically clear. The restructured space has semi (or in-between)-spatial characteristics such as the intersection in inside and outside of the pedestrian's circulation and the mixture of programs. This study could serve as principal references in presenting the systematic analysis of directions of the shared spatial structure for the urban campus where new educational space is required due to the changes in the university system.

A systemic review on the factors affecting food catering hygiene was conducted to provide information for risk management of food catering in Korea. In total 47 keywords relating to food catering and food hygiene were searched for published journals in the DBpia for the last decade (2005-2014). As a result, 1,178 published papers were searched and 142 articles were collected by the expert review. To find the major factors affecting food catering and microbial safety, an analysis based on organization and stakeholder were conducted. School catering (64 papers) was a major target rather than industry (5 pagers) or hospitals (3 papers) in the selected articles. The factors affecting school catering were "system/facility/equipment (15 papers)", "hygiene education (12 papers)", "production/delivery company (6 papers)", food materials (4 papers)" and "any combination of the above factors (9 papers)". The major problems are follow. 1) The problems of "system/facility/equipment" were improper space division/separation, lack of mass cooking utensil, lack of hygiene control equipment, difficulty in temperature and humidity control, and lack of cooperation in the HACCP team (dietitian's position), poor hygienic classroom in the case of class dining (students'), hard workload/intensity of labor, poor condition of cook's safety (cook's) and lack of parents' monitoring activity (parents'). 2) The problem of "hygiene education' were related to formal and perfunctory hygiene education, lack of HACCP education, lack of compliance of hygiene practice (cook's), lack of personal hygiene education and little effect of education (students'). 3) The problems of "production/delivery company" were related to hygiene of delivery truck and temperature control, hygiene of employee in the supplying company and control of non-accredited HACCP company. 4) The area of "food materials" cited were distrust of safety regarding to raw materials, fresh cut produces, and pre-treated food materials. 5) In addition, job stability/the salary can affect the occupational satisfaction and job commitment. And job stress can affect the performance and the hygiene practice. It is necessary for the government to allocate budget for facility and equipment, conduct field survey, improve hygiene training program and inspection, prepare certification system, improve working condition of employees, and introducing hygiene and layout consulting by experts. The results from this study can be used to prepare education programs and develop technology for improving food catering hygiene and providing information.

Considering that rural village had evolved through a long-sustained effort of harmnization with nature, there should be the wisdom not only to reflect the level of rural resident's housing demand, but also to conserve the traditional characteristics of high-valuation in the modern rural housing. In Korea , standard design proposals of rural houses had been made public three times ; in 1972 , 1984 and 1995. so , firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through, the positive acceptance of residents' opinion living inthe houses built by standard design proposals in 1970 ~1980's, improved design principles and an alternative model were proposed , finally. The inner-space structed of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the " open system". In 1980s, the basic design principle changed to the 'closed system' in which the living room being the focus of indoor family life, and , in 1990s, progressively, therural housing developed to the high qualified type by the spatial enlargement and with increased equipements. However, this structural change of rural house brought about the problem of functional separatioon between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. conclusively in this study, newoly arranged "open system" was recommended , as a basic design principle for theinner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criterial was proposed as follows ; 1. The living room be directly linked to the front-yard and centrally placed, the addtional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The kitchen also be directly linked to side-yard and to livng room , for the convenience of farming activities and the shortening of path flow housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet and-bathroom , of which function would be for undressing of working clothes, quickwashing and ordinary working.nd ordinary working.
