Purpose: To find the effects of semi-Fowler's position on the post-operative recovery for patients with laparoscopic abdominal surgery in recovery room. Method: The research was performed by nonequivalent control group non-synchronized quasi-experimental design. The subjects are forty patients who had laparoscopic abdominal surgery in a hospital from Aug. thru Nov. of 2003. Post-recovery scores and $O_2$saturation degree were measured. The experimental group was place in semi fowler's position while the control group was placed in supine position. The homogeneity between the control group and experimental group was analyzed using the Chi-square, and the hypothesis were tested using t-test. Result: 1. The patients in the experimental group placed in semi fowler's position showed significant higher post-recovery scores than those in the control group who were in a supine position. 2. The patients in the experimental group who were in semi Fowler's position showed no significant higher $O_2$ saturation degree than those in the control group who were in supine position. Conclusion: Based on the results described above, it is considered that the semi-Fowler's position might be effective in enhancing the post-operative recovery score of the patients with laparoscopic abdominal surgery in recovery room.

Purpose: The purpose of this study was to examine the influence of safety control, nursing professionalism, and burnout on patient safety management activities of operating room nurses. Methods: Data were collected from August 10 to September 26, 2022 from 154 operating nurses who consented to participate and have worked for more than six months in hospitals with 300 or more beds in the Seoul-Incheon area. The data were analyzed using the SPSS/WIN 26.0 program. Results: The main factors affecting patient safety management activities were safety control (β=.36, p<.001) and nursing professionalism (β=.15, p=.046). The regression model was statistically significant (F=13.49, p<.001), with explanatory power of approximately 28.6%. Conclusion: Based on these results, the aforementioned activities can be promoted by preparing and providing an operating room safety management program that can improve safety control and establish proper nursing professionalism.

The temperature and humidity distribution in a dry room are studied numerically by using standard$\kappa-\varepsilon$ turbulence model. In order to evaluate effective heat and moisture ventilation characteristics inside the room, the heat removal capacity and moisture exhaust efficiency are introduced. An effective ventilation control is analyzed by evaluating quantitatively temperature and humidity distributions. It was found that the mean absolute humidity inside the room was almost constant with approximately 0.1905g/kg air regardless of the models and the heat generation rates. This was believed that the moisture generation by workers was relatively small. 40% improvement of the critical decay time was achieved, through the modifications of design variables.

This study has been conducted to evaluate the applicability of the control method in the dehumidification-integrated radiant floor cooling system in terms of stability of the room air temperature and the control variables through experiments. To do this, the relationship between the control variables in preventing floor surface condensation is first analyzed and the control method is predetermined through simulations. The results are as follows. First, it is necessary to determine the operation status of the dehumidification system according to the relationship between floor surface temperature and dew point temperature in the conditioned space. Second, outdoor reset with indoor temperature feedback control is better than on/off bang-bang control with respect to temperature stability in controlling the room air temperature and the possibility of energy savings. Finally, the humidity sensor can be located with the current thermostat in that there are small differences in absolute humidity in vertical distribution.

Purpose : The purpose of study was to identify to analysis of core nursing interventions performed by Operating Room nurses. Method : The subjects of the study were arbitrarily selected nurses(n=104) working in Operating Room. The period for data collection was 15 days from July, 15, 2002 to July, 30. 2002. The instrument for study was 486 Nursing Interventions Classification developed by McClosky & Bulechek(2000) and was translated into Korean. In 486 nursing interventions, 57 nursing interventions were selected by more than half of 47 professional nurses group of Operating Room. 57 nursing interventions were used as a secondary questionnaire. In the secondary questionnaire, labels and definitions of all 57 interventions were listed. The collected data were self reported by Operating Room nurses. The data were analysed with SPSS program. Result : In 57 nursing interventions, the 'Behavior' domain was the most frequently used. Core interventions of Operating Room were performed several times a day by more than 50% of Operating Room nurses. Core interventions of Operating Room were 16 Core interventions, 7 classes, 5 domains. In the core interventions, the 'Physiological:Complex' domain was the most frequently used. Core interventions of Operating Room were Surgical Preperation, Infection Control:Intraoperative, Surgical Precautions, Fall Prevention, Documentation, Surgical Assistance, Environmental Management:Safety, Skin Surveillance, Physical Restraint, Pressure Ulcer Prevention, Environmental Management:Comfort, Infection Protection, Presence, Emotional Support, Specimen Management, Shift Report. Conclusion : Core interventions of Operating Room have implications for nursing care practice, nursing education, nursing research, and nursing information system in Operating Room.

At this study, we are developing a possible control system through remote monitoring for fire protection in various chemical factory facilities. It's possible to do real time confirmation of a normal operation presence of the various equipment installed in a chemical factory through the internet network at a fire fighting head office, an area fire department and a chemical factory situation room using this remote monitoring control system. When occurring, abnormal operation is the remote monitoring control system, which can check this immediately and notify the situation room administrator. After it was tested using developed remote monitoring control system, the remote monitoring for which the internet network was used confirmed possible.

To evaluate the smoke control systems, the large eddy simulation turbulence model based Fire Dynamics Simulate was applied to a 2m $\times$ 2m $\times$ 2.4m room with an opening. The smoke removal rate was investigated for three different smoke control systems: ventilation, extraction and pressurization. When the opening was closed, the smoke removal rates of the smoke control systems were almost the same as expected. The pressurization system showed a lower smoke removal rate compared with the other two smoke control systems for the room with the opening, and hence the pressurization system might not be efficient for a place with large openings. It was shown that the lower extraction flowrate is, the longer time the ventilation system requires to remove smoke. From these results, the ventilation system is recommended for subway stations where several large openings exist.
