The number of clinics for Oriental Clinic is increasing sharply in Korea after the inception of National Health Insurance System in 1987. However there have been many troubles in making efficient plans for oriental clinic facilities because of the lack of proper guidelines related to the design of them. This research was conducted as part of the planning project for the "G" Oriental Clinic. The purpose of this project Is to place a optimal number of beds in a small oriental clinic and medical-environmental friendly design After arranging necessary spaces, such as the Director's Office, Herbal Medicine Preparation Room, Multipurpose Room, Medicine Cabinet, and Waiting Room in the clinic, partitions are used to differentiate the spaces and the storage area.

One of the major changes in the information era is that the concept of workplace is changing, Therefore this research is to provide basic data for future home office design by surveying office workers's opinions about preferred design for home office. This research is based on a survey of 215 office workers in Seoul. The major findings are ; Office workers prefer an isolated type of workplace that is arranged by U-shped workstation at home. Office workers preferred ivory color of walls and ceiling in home office, Brown color for the floor and brown ivory beige green and grey colors are preferred for the furniture. For home office furniture office workers put to an importance on desk chair computer table cabinet filbox sofa mobil lack credenza, and tea table.

The purpose of this study was to design rural kitchen furnitures. Thirty seven rural houses were selected for this study. Present and past uses of space for cooling and dining were investigated by a field survey method. The Major findings were that ; 1) Sink, mixing, and range centers should be installed in rural kitchen 2) The depth of working center, 550-600mm was recommended. And working space cold be added by 150mm in depth and 100mm in height. The height of working center, 820mm-850mm was recommended . The minimum width of sink was 900 mm and the optimum one was 1200mm. The optimum width of mixing center and cooking center were 600m respectively 3) In the low ceiling of kitchen or the wooden structure of kitchen, a wall cabinet without upper cupboard was recommended. On the basis of the results, four types of rural kitchen furnitures is proposed.

The purpose of this study was to devise guidelines for the kitchen workspace of the aged by examining current usage. To achieve this objective, surveys were conducted and measurement were taken between June 15 and lune 30, 2005. The data were gathered from 50 women over 65- years-old who live in the downtown and suburbs of Seoul, Korea. The collected data were processed using SPSS 12.0 for Microsoft Windows and resulted in the following conclusions: The kitchen for the aged needs to be laid out in ㄱ-shape and the refrigerator needs to be positioned prominently. The height of the work counter is relative to the user's height (${\times}0.49{\sim}056$). and the length varies depending on the available space of the house and the type of work counter needed: however it was found that it should be at least 270cm Concerning the depth of the work counter, the standard sizes (60cm) currently on the market did not cause any inconvenience. It was found that the sink must be designed to allow for some space at the bottom so as to ensure comfortable sedentary work. Also, an electrical oven was preferred over a gas-fuelled one. Finally, the height of the upper cabinet should be relative to the user's height at ${\times}0.85{\sim}1.0$ from the floor to the bottom of the cabinet.

Gas cylinder cabinets have risks such as cylinder explosion and scattering of debris when a fire occurs. These risks are likely to cause gas spills and cause secondary damage. In order to reduce damage, it is very important to secure the fire resistance performance of the gas cylinder cabinet. In foreign countries, NFPA codes in the United States and EN-14470-2 in Europe stipulate fire resistance test standards for gas cylinder cabinets to protect internal cylinders for a certain period of time in a situation where gas cylinder cabinets are exposed to flames. However, in Korea, only internal pressure performance and airtight performance standards are specified, and the target is limited to piping, and research and regulations for the fire resistance performance of gas cylinder cabinets are insufficient compared to overseas. Therefore, in this study, finite element analysis was used to establish fire resistance standards for domestic gas cylinder cabinets. In the event of a fire, optimal conditions are derived in terms of structure and material.

Opening commercial service of KTX at the time of demanding more flexible train set for HONAM line and JEONLA line, it's necessary for the Korean High speed train, performing the stabilization; to modify the design in aspect of passenger and maintenance. In order to ensure the optimized interior design in Korean High speed train, it is necessary to review the major items such as disabled passenger facility, toilet, seat arrangement, compartment partition and door, access door, electrical cabinet, color and paint through the European standard and compare with other high speed train.

Most washing machines are now produced as a drum-type, where a washing drum mounted on a suspension system with springs and dampers, to minimize the transmittance of the vibration from the drum to the cabinet. The purpose of this paper is to develop optimized suspension system of the drum washing machine which minimizes transmission of disturbing vibration and force. In this paper, a method for optimizing suspension system of the drum washing machine is presented using ADAMS. The design variables to optimize are extracted using Sequential Quadratic Programming(SQP) in ADAMS. To evaluate optimized spring constants and damping coefficients of the drum washing machine, simulation was done to compare the vibration attenuation performances before and after the optimization. The results of simulation show that the optimized suspension system has better performance than before the optimization.

This paper describes the results of reliability prediction analysis of control rod control system, which is being developed as part of KNICS project. The results of reliability prediction indicate MTBF(Mean Time Between Failure) of cards for control rod control system. A purpose of reliability prediction is to evaluate MTBF of cards, identify the design drawbacks of cards, and propose design improvement to a designer to help design the more reliable control rod control system. This reliability prediction analysis used the the part count and part stress method in the basis of MIL-HDBK-217F.

This paper deals with the design, implementation, and test of a CRCS for nuclear power plants. Although CRCS is still classified into non-safety class, much attention on its reliability issue has been given so far because of its importance for the stable operation of the reactor in the plant. In terms of technical aspects, our system adopts a full-duplex configuration to enhance reliability in contrast to the existing systems that are all simplex.
