A study of domestic furniture arrangements may reveal the living style relevant to the room as conceived and coded by occupants and the effects of the physical environment on the structure of behavior settings. The purpose of this study was to investigate, through analizing the furniture usage and behavior as a non-reactive and activity oriented behavioral measures, the occupants` domestic habits as a living style using MDS. MDS(multidimensional scaling technique) is a statistical technique for creating a spatial representation of data. It Is a particularly appropriate technique for analizing qualitative data such as the furniture usage and behavior because it takes into account all of the relationships between items. For the MDS analysis, the furniture usage and behavior examined by housing types based on 114 households in Seoul. The result of spatial configuration by MDS has three dimensions : recogn;lion of room function, pattern of room organization, understanding of room meaning. The effect of housing types for dimensions is identical but configuration of furniture items is different.

The purpose of this study was to suggest usage that all family members could find satisfaction in the way to use furniture and living room. First of all, methods of research for this purpose were to grip on the points of difference and sameness on the attitude and the actual condition about furniture usage and living room between housewives and woman university students. To make analysis the data, frequency, $\chi$2-test, t-test, F-test and factor analysis were used. The major results are as follows ; 1. There were significant differences in the using time, time zone and life behavior in living room. 2. In furniture usage, housewives and woman university students have significant differences. 3. According to the results of making investigation into degree of satisfaction abut furniture and living room usage, housewives and woman university students have significant differences.

Ventilation of the marine engine room is very important for the health of the workers as well as the nomal operation of machines. To find proper ventilation conditions of this engine room, numerical simulation with standard k-.epsilon. model was carried out. In the present study, the marine engine room is considered as a closed space with a heat source and forced ventilation ducts. The injection angle of air supply is found to be important. Injection with downword angle depresses recirculation flow, causing a strong steam in the wider space of the room. Ventilation and removal of the released heat are promoted with this pattern. There is a possibility of local extreme heating at the upper surface of engine when supply and exhaust ports of air are in bilateral symmetry. The effect of the increase of exhaust port area on ventilation decreases as the number of supply port increases.

This study proposed the optimum design values for the biological clean room system observing the regulations of Hazard Analysis Critical Control Point (HACCP). Even though the standard for industrial clean room system has been well established, the basis for biological food clean room system is the first stage. In order to prevent the contaminations in advance for food storages, processes, and distributions, the criterion of Hazard Analysis Critical Control Point is positively required. This study also suggested the possible ways of how to avoid the hazardous contaminations.

Cohousing is communities balance the traditional advantages of home ownership with the benefits of shared common facilities and ongoing connections with your neighbors. It is characterized by private dwellings with their own kitchen living-dining room etc, but also extensive common facilities. These cooperative neighborhoods are one of the most promising solutions to many of today's most challenging social and environmental concerns. The purpose of this study is suggest planning direction to cohousing as alternative house. It focuses on the planning method through case study. The result of the study are summarized as follow ; Size of cohousing is 20${\sim}$50 family. Location of cohousing is urban. Type of house is detached house+row house. Size per family is 0${\sim}$15m$^2$. Common house makes up kitchen, dining-room living-room, guest room nursery room and so on.

Nowadays, Korean society is quickly transforming into an aging society. There are lots of problems resulting from old aged society. First of all, in the case of medical service, it is an urgent task to find out what is the most proper care for the elderly in order to reduce medical expenses. It can be said that the geriatric hospital has to be designed to give adequate medical service to the elderly. However, it is hard to find out what the differences is between the general hospital and the geriatric hospital. Especially, the plan of the patient room has to reflect thoughtful consideration relating to characteristics of the elderly due to the fact that there is a close connection between the patient room and residence. Therefore this study aims to suggest the guideline and the plan of the patient room for the elderly.

Purpose: The purpose of this study was to develop the medical error reporting system and to validate an trait of error in the Operating Room. Methods: Descriptive research design was used. The subjects were 30 nurses with below 5-year-career in a University Hospital. Data was collected from 11, April until 22, April, 2005 using web-based error reporting system. Data was analyzed by mean, standard deviation, $X^{2}-test$ using SPSS WIN 10.0 program. Results: A time of medical error in operating room nursing frequent occurrence was from 12 pm. to 4pm. 'Lack of sterile materials' management' was the best frequent occurrence of medical error in operating room nursing. Conclusion: The findings of this study show that manager of healthcare organization must develop the error reporting system more familiar and ordinary. Afterward, we prevent the repetitive medical errors in nursing care through analyzing of error reporting system.

Construction machinery includes an engine enclosure separated from a cooling system enclosure by a wall to reduce noise and advance cooling system performance. For this structure, however, the axial fan cannot be of benefit to the engine room, and so the temperature rise in the engine room makes several bad conditions. This paper proposes that hot air in engine room is evacuated tv secondary pipe using jet pump. This paper demonstrates the structure and the effect of jet pump and useful guideline on design of area, length, and shape of secondary pipe to maximize the effect of jet pump.

It is known that elimination of ship engine room noise is impossible thing, so the working environment in the engine room is getting worse because ships are recently built with huge engines to take higher sailing power. In the yacht and cruise yacht, the engine room noise is more serious because they have bigger engines relative to their hull sizes. The noise generated from the main engine makes the employee to hearing loss and the transmitted noise make the uncomfortable conditions in the cabins of ship. The noise generated by ship engine must be attenuate for the employee and passenger. In yacht and cruise yacht, the noise levels in cabines are the most important criterions to the value of commodities. In this study, the noise absorbtion barrier which have resonators is experimentally studied by the 1/3 octave band noise elimination rates(%).

Four types of different flow inlet models were tested to improve the flow uniformity at the inlet of the radiator and to prevent thermal damages of auxiliary units from the hot air in the bus engine room. Measurements and numerical calculations were performed and their results were in a good agreement with each other. Simultaneously temperature measurements were carried out under the conditions of actual bus driving. As designing the new flow inlet at the partition board which seperates the engine space and radiator space, flow circulation can be achieved and fresh air comes into the engine room from the bottom. It was proved that new inlet makes the one air temperature cooling down in the engine room, the other uniformity improvement.
