Lecture room, space for student to study, need to get exactly information and show up what students are required So, problems for illuminated environments are low effect of studying, and that students may get weak-sighted. Research is required to get enough lighting for lecture room which students spend most their time. If we compare lighting system for recent college lecture room with computer simulation, lighting system at the lecture room with down light will be improve intensity of illumination. Therefore we can get economical benefit and save energy.

The purpose of this study was to the characteristics of the interior space composition for luxurious apartments and the trend of interior design. Surveying visits were made to 30 model houses for which individual apartments of 8 million Won or more per pyeong (about 3.30 square meters) were on sale from December 1999 through November 2000 in Seoul and suburb area, pundang. The major finding were summarized as follows; (1) The characteristics of the planes indicated that the living-room separation type accounted for the majority, which was not generally different from common apartments. The master zone divided several room. The main room which conventionally played the roles of the family gathering space and the second room shared by family members, was designed exclusively for husband and wife. Distinctively separated from the other spaces, it was to be used for personalized space, together with bathroom for the couple, dressing room, or study. Attempts were made for the high-class apartments to get away from the common uniformed apartments, such as the yard-type balcony or the second entrance in consideration of the moving path. (2) The characteristics of the interior designs showed that the detailed attention was paid to every composing element for the emphasis of the high quality image. The factors determining the quality were finishing materials, kitchen furniture, hygienic ceramics, electrical appliances water supply equipment, or functional storage closet.

A window increases the lighting quality of a space by allowing daylight into the space, and maintains visual contact with the outside. Moreover, the window with a preferred view provides many benefits such as psychological satisfaction, occupants' health and improved environmental quality. This study aimed to investigate how view elements and window luminance influence occupants' seating preference in a living room. The experiment was carried out in a mock-up model with thirty-two subjects (17 men and 15 women). The nine seating positions in a living room have different view such as natural view (trees or sky) and man-made view (paving and roof top). Subjects were asked to select a position in the room where they felt most visual comfort. Simultaneously Photolux 2.1 software was used to analyze the window luminance. The experiment results indicated that subjects prefer to be seated near a window and feel comfort in a seating overlooking the trees and sky. This would indicate that the natural elements of the view and a distance to the window affect seating preference to the occupants.

Purpose: The purpose of this study was to identify the factors influencing on burnout in operating room nurses. Methods: Using a cross-sectional design, a total of 109 operating room nurses working at 7 general hospitals with 300 beds or more in B city were analyzed. The instruments used for this study assessed job stress, resilience, professional identity, and burnout. Data was analyzed using descriptive statistics, a t-test, an ANOVA, a Pearson's correlation coefficient and a multiple regression analysis. Results: There was a statistically significant correlation between burnout and job stress (r=.53, p<.001), resilience (r=-.59, p<.001), and professional identity (r=-.47, p<.001). The factors influencing burnout include job stress (${\beta}=.27$, p<.001), resilience(${\beta}=-.37$, p<.001), dissatisfaction with the nursing job (${\beta}=.32$, p<.001), and moderate satisfaction with the nursing job (${\beta}=.19$, p=.014), and the explanatory power was 53.0%. Conclusions: The results suggest that intervention to reduce job stress and to improve resilience, which were the factors influencing burnout in operating room nurses, is necessary.

Purpose: This study was designed to investigate the relationships of the types of nurse staffing, the competency of nursing performance and job satisfaction by analyzing the types of nurse staffing in operating room. Method: The subjects were 472 nurses who work in operating room. The instruments used in this study were three tools: competency of nursing performance, job satisfaction and type of nurse staffing. Result: Type 4 was most in the type of nurse staffing of the subjects. According to the type of nurse staffing, the competency of nursing performance was significantly different. There was significant difference in the competency of nursing performance according to age, marital status, bachelor, employ, position, and career, and job satisfaction according to age, position, and career. In opinion about the ideal type of nurse staffing, type 2 was most regardless of career. Conclusion: Type 4 which has lower competency of nursing performance was adopted in many hospitals now but, type 2 which has highest competency of nursing performance was selected by many nurses as the best one. So, it should be considered the type of nurse staffing of in operating room and change it.

Liquid crystal displays (LCD's) are continuously coated with some chemicals in the clean room of a factory. Spreading of these chemicals is causing serious problems both in controlling clean room quality as well as to the workers inside the factory. It is required to alleviate or properly control the offensive odor which is mainly composed of propylene glycol mono ethyl acetate, novolak resin and photo active compound. The control strategy employed is to bleed the offensive odor gas out the clean room. A full scale 3D CFD model was created with anisotropic porous media, chemical species transport with no volumetric reaction, and thermal diffusion with propane gas (tracer gas) to simulate the odor spreading. A segregated implicit solver with standard k-$\varepsilon$ model is employed. The detailed CFD analysis made it possible to develop an effective method of ventilating the coater room and optimizing their capacities.

The objective of this study is to provide new direction on house design in consideration of the user's life pattern. To this end, pc usage status at home, demand for pc using space, and requirements for pc room interior were analyzed. A survey was taken by parents and the SPSS win.10 was applied for analysis. The survey was conducted for 2 months, starting May 2004 to see the computer usage at home, demand and satisfaction for the computer's room. The results of this study were as follows; The oldest son or daughter in a family was the main user of the computer, posting 71%. 42percent of respondents said they used the pc in their son's and daughter's room while 36% answered living room. It reflects that the whole family want to use the pc in their sharing room, or for their children's convenience. Currently, inconvenience of space-related constraints for using the pc was not that high, which possibly stems from a lack of awareness of inconvenience in using the pc. However, the need for furniture and space for refreshment was suggested. Through this study, it is expected that new housing designs need to be made to reflect these requirements into interior design and building plan for user's convenience.
