This study was intended to carry out the Post-Occupancy Evaluation of ward design of one general hospital in Busan. On the basis of this POE, the design guidelines for the user-oriented hospital were suggested. The subjects were 47 in-patients, 47 families, and 49 nurses in this hospital. The POE was carried out in three aspects of ward design: function, interior finishes and color, and psychological aspects. The functional aspects were the view, location, size, furniture arrangement, safety, accessibility, and storage; The interior finishes and color were the ones of floor, wall and ceiling of each room in the ward; The psychological ones were the visual and acoustical privacy, control, home-likeness, consideration for the care-giver, social interaction, familarity, and way-finding. The users were relatively satisfied with the functional aspects except for the room size of each room. They were also satisfied with the interior finishes and color. However, they were dissatisfied with the psychological aspects of ward design. As for the difference among users, the satisfaction degree of patients and their families with the functional and psychological aspects of ward design was higher than that of nurses, and the satisfaction degree with the interior finishes and color showed having no difference.

In this study, monometallic Pt and bimetallic Pt-Ru, Pt-Ir were supported to TiO₂. In order to distribute metals uniformly, and Xylene, toluene and MEK were used as reactants. The monometallic or bimetallic catalysts were prepared by the excess wetness impregnation method and were characterized by XPS and BET analysis. As a result, Pt-Ru, Pt-Ir bimetallic catalysts were showed higher conversion than Pt monometallic catalyst. Pt-Ir bimetallic catalyst was showed highest conversion on the TiO₂ support. In the VOCs oxidation, Pt-Ir bimetallic catalyst had multipoint active sites, so it improved the range of Pt metal state. Therefore, bimetallic catalysts were higher conversion of VOCs than monometallic ones. In the kinetics, VOCs oxidation was appeared on the first order reaction. In this study, the use of small amount of Jr to Pt promoted oxidation conversion of VOCs.

School has a responsibility on its students for making their ideal sense of values and guiding them correctly to physical, mental and social health. If we consider this fact, we'll understand the reason why the physical education in middle school has a awful lot meaning to the students. So the purpose of this study is to investigate the influence that an Intramural Sports Involvement of a Middle School has on social implications development. The subject of this study were 330 non-athletes Middle School students in Daejeon Metropolitan City selected by the stratified cluster random sampling. And I studied 317 students among them finally. For the method of collecting the data, I chose the questionnaire written by Jung, Bum-Mo(1971) and standardized by the study of Han, Tae-Ryong. And the numerical value of this data was Cronbach' a=.62 For analyzing the data, I used the technical statistics and the one-way ANOVA. So the conclusion of the influences that an Intramural Sports Involvement of a Middle School has on social implications development. 1. The development of socialization according to the vital statistical has similar differences among groups. About the difference of the development of socialization according to the gender, male students are superior to female students in direction and self control and female students are superior to male students in stability and social contact. About the difference of the development of socialization according to the grade, lower graders are superior to higher graders. 2. The development of socialization according to an Intramural Sports participation has similar differences among groups. About the difference of the development of socialization according to the time of the participation, the activity and the direction are proportional to the time or the participation. And about the difference of the development of socialization according to the period of the participation, the activity and the self control are proportional to the period of the participation.

This paper reports a suitable operating mode and condition through the economic and exergy analysis to a cogeneration power plant cycle with computer simulation. The exergy analysis that permits to predict the exergy losses in each component furnishes information to the quantity and the place of exergy loss. The simulation condition is to generate constant electricity in spite of the load change of process steam when the supply of process steam and pressure of condenser is changed, devided with sixteen kinds of operating modes according to the ratio of process steam by the auxiliary boiler to steam extracted from the high pressure turbine. Performing the computer simulation for the economic and exergy analysis with above condition, the results show that a cogeneration efficiency is increased as process steam supply is increased and the ratio of process steam by auxiliary boiler is decreased. Oherwise, a economics rate and a cogeneration efficiency are decreased as the pressure of the condenser is increased. And the boiler and the condenser have about 96 to 98 percent of the total exergy losses in a cogeneration power plant cycle.
