Background : The purpose of this study is to investigate the influencing factors on the length of emergency department stay of patients with acute myocardial infraction. Methods : we reviewed medical records of all patients who were Hospitalized with acute myocardial infraction from March 1, 2002 to February 28, 2003. Results : The average length of stay in the emergency room of the subjects was 182.74 minutes. After the emergency room treatment, 48.1% of the subjects were transferred to intensive care unit. The hospitalization through emergency room mostly took place in the office hours. There were more patients on Monday. The influencing factors on the length of stay in the emergency room of patients with acute myocardial infraction were emergency room arrival time which was classified in seasons, treatment hours of specialized doctors, medical care insurance and required time of radiologic examination. Conclusion : In order to reduce the length of emergency room stay, it might be an available solution secure enough spaces, facility, and staff of the radiologic test only for the patients of the emergency room. And the effective use of emergency facility and space, establishment of standardized treatment guideline, and provision of emergency treatment support system are also needed.

Nursing Homes are different from other medical facilities, because they have a living space. And most of residents in a nursing home have dementia, therefore nursing homes are in control of outdoor activities for resident's safety and most of residents live in the living room at the daytime. The purpose of this study is analysis of spacial behaviors of residents in the living room, and reflection of the analysis into the architectural plan of nursing homes.There are two activities, individual activity and social interchange activity, in a living room and the role of a living room is semi-private space that includes both of them. Most numerous activities are watching TV and take a eat. Activities are different in accordance with the position at the living room. Individual activity and social interchange activity is same ratio in the middle and the ratio of social interchange activities are more than individuals in outside of living room. but alcove use of private.The types of living rooms are distinguished by combination of functions of livingroom, activity-room, and diningroom. The activity of use of residents have been shown different phases following the types of livingroom. The type of combination has been seen high rate of use and private activities and social communications are expressed evenly. The type of mixing has been seen low rae of use, but two activities, the above, are equal. The type of separation has been seen not only low rate of use, but also there has been only private activities.

This study was carried out to focus on the user-oriented design of patients' room in general hospital. The purpose of the study was to examine the users' evaluation on their patients' rooms in H General Hospital and to suggest how to improve the patients' room design. The users were inpatients, care givers, and nurses, 300 subjects of each 100 users in H hospital. They evaluated 26 items related to the patients' room design using by 5-points Likert scale. Also, they answered three elements which bothered them, what needed improvement, and what they feel ill at ease. The results were as followings; 1) The users evaluated positively the location and size of window. This implies that the current one is relatively ideal and deserve to be maintained. 2) The users responded negatively to the thermostat system and the space for care-givers. 3) The lack of space for care-givers and visitors, common use of refrigerator and bathroom, and the lack of space bothered the users. 4) Most users mentioned the lack of space in patients' room. This implies that it needs to consider the change of the person number per patient's room, from 5 persons to 4 ones. 5) The lacks of sleeping space, dining space, and bathroom space bothered the care-givers. This implies that the space for care-givers such as sleeping, dinging, and bathing should be considered in patients' room.

Bio Clean Room(BCR) and pharmaceutical product manufacturing facilities require careful assessment of many factors, including HVAC, controls, room finishes, process equipment, room operations, and utilities. Flow of equipment, personnel, and product must also be considered along with system flexibility, redundancy, and maintenance shutdown strategies. It is important to involve designers, operators, commissioning staff, quality control, maintenance, constructors, validation personnel, and the production representative during the conceptual stage of design. Critical variables for room environment and types of controls vary greatly with the clean space's intended purpose. It is particularly important to determine critical parameters with quality assurance to set limits and safety factors for temperature, humidity, room pressure, and other control requirements. In this paper, oxygen cluster ion equipment was utilized in order to enhance the indoor air quality and to prevent the airborne infection of ward in hospital. Moreover, the performance test of the equipment was also performed in order to develop the optimal sterilization system of BCR using the equipment.

Purpose : Due to the shortage of the room for the disabled, it may be difficult to use the accommodation for the disabled (especially wheelchair users). The purpose of this paper is to propose a universal design(UD) application for all rooms to solve the problems caused by the shortage and the decrease of the usage rate of the rooms for the disabled. Methods : Classify and analyze the type of room and bathroom according to the survey. The space of the room is classified into six types mainly based on the relation and location among the entrance, the bathroom, and the bedroom. Also, the bathroom is classified into 20 types considering the positional relationship with the entrance and between sanitary fixture. By using these types, FGI survey will be conducted and the application of UD will be reviewed and presented. Results : We analyzed by using the types of the room and the bathroom. One of majority type in the actual research and two of UD applicable types from FGI, are shown UD application. In addition, the bathroom were analyzed about four types from FGI. The room were shown about the activity space and the furniture layout for UD. The bathroom were shown about the space for the entrance, the internal activitiy space and the arrangement of the sanitary fixture. Implications : By comparing and analyzing through type classification, it was found that universal design can be applied to all rooms. Therefore, it is expected that the UD will be activated in all rooms of the accommodation.

If human beings could make friends with nature, it would be a truly wellbeing. This project has selected the design concept under the supposition that human beings and the nature become friends. This residential house, which is consisted of one ground floor and two underground floors, is confronting the mountains that surround the residential complex. Residents can enjoy viewing the mountains from the living room. The garden is created by using this given environment in maximum. The walls are made up with rocks, and a small pond is formed with water from the mountain, presenting another attractive sight. Through the connection rather than the break between mountain and garden, living room and garden, and again garden and mountain, the dialogue with nature was attempted. The water of the pond in the garden flows down along the walls and creates another water space at the gate area of the house. Passing through the entrance, there are a living room, a kitchen, a bedroom for spouses, a common bathroom, and a library on the ground floor. On the second floor, there are two rooms, a bathroom, and a mini living room. The platform of living room on the 1st floor is lowered to produce the comfortable living room with the hearth. From the view of living room, the garden with full feeling of nature can give a good emotional rest for modem people who want the mental relaxation. The marble stones are used as its material to present rich texture and sophisticated image presentation. The hearth in the living room is harmonized with high-tech electronic home appliances and surrounding accessories. On the kitchen, the high-glossy materials are used to express the external appearance neatly and the depository function is more improved for housewives.

Most of the domestic cold storage rooms are inefficient for agricultural products because of temperature gradients inside the storage rooms. Temperature gradients are developed mainly by improper airflow pattern inside the storage room, which is a main cause of the spoilage of the agricultural products. There proper airflow pattern is essential to minimize these temperature gradients and the spoilage. The performance and characteristics of a cold storage room were determined as a function of airflow pattern and temperature distribution in forced circulation cold storage room. A commercial CFD(computational fluid dynamics) code was used to simulate 3-D airflow in the cold storage room. Solving the flow equations for the storage room, a standard k-$\varepsilon$ turbulent model was implemented to calculate steady state turbulent velocity distribution. The CFD prediction results were compared with temperature measurements inside the cold storage room. In case of pallet storage, Temperature gradients inside pallet storage was reduced because the contact area of cold air expanded through an alley of airflow in storage. But is case of bulk storage, the last temperature of storage considerably rose more than the initial temperature of storage. The reason was that bulk storage didn't include any alley of airflow in storage.

This study investigated the pressure difference distribution and the flow characteristics among room, ancillary room, and stair case by carrying out the numerical simulations on the air flow inside the pressurized air supply smoke control system. Numerical simulations were conducted to analyze pressure and velocity distribution of compartments by pressurized air supply for the air-leakage test facility which was built to measure the effective leakage area. In this study, the leakage of air was considered by locating the narrow slit onto fire door and window of room. Simulated results using this method precisely followed the previous experimental results for the pressure differences between the stair case and ancillary room. Predicted results showed that the local leakage of air rarely affected the overall flow pattern and pressure distribution. Although the average velocity over the door between room and ancillary room satisfied the regulation for fire safety, it was certified the unsafe outflow to ancillary room could be occurred in the local position such as the upper part of the door.

The probability of lethality of personnel targets inside a room is a key issue at assessing effectiveness of a weapon system. In this study, the minimum charge weight to achieve 100% lethality of personnel targets inside a box-type room is proposed at each side length of a base of a room. A fast running blast wave model is used to simulate the pressure-time histories of the blast generated by an internal explosion inside a room, and Axelsson SP method is used to evaluate the lethality of personnel targets under the blast. 176 different internal explosion scenarios are simulated for cases of TNT weights ranging from 20kg to 170kg inside a room whose square base has a side length ranging from 5m to 15m. A linear model and a charge-density model were developed to predict the minimum charge weight to achieve 100% lethality inside a room given a length of a base of a room.
