Background : The necessity of unify and standardize codes used at hospital has been emphasized since OCS (Order Communicating System) was adopted. Therefore, the purpose of this study were to standardize operation code by continuous training of the ICD-9-CM code that is used as standard code in OCS program at operating room. Method : In 400 operation data, operation code entered in OCS program at operating room was compared to operation name recorded in medical record. In addition, a matching rate between input data of operation code by medical record department and computing input data of operation code in 3,710 cases was compared for each department. User operation name and operation code were matched and major diagnosis by operation department and operation name were also matched. Results : User operation name was reflected in operation classification code in detail, and operation code entered on user was registered. Input rate and matching rate of operation code were gradually improved after improvement activity. In particular, a matching rate was high at ophthalmology where operation name is segmented. Plastic surgery and orthopedics with a lot of emergency operation and comprehensive operation name show low input rates. Conclusions : As the medical field makes progress in computerlization, awareness of information exchange and sharing becomes higher. Among codes to classified medical institution, codes related to surgical operation are all different by user of hospital and department. Computerlization and standardization is essential. And when efforts of standardization continue in alliance with individual hospital and institution, initiative of preparing medical policy data at a national level will be accelerated.

The individual rotten water purification tank recently discharges wastewater and sewage through the outlet without purification ability. The outlet water and affiliated water purification tank with microorganism cultivator tank cultivates microorganism and then drops the value BOD, COD of sewage and discharges the quality of water into the outlet. The blower and water pump operating continuously prompts the waste of energy and deterioration of equipment. Each room of deposition tank, foaming tank, microorganism cultivator tank is equipment with the sludge detection senses so it can detect the density of each room. The power-drive plant of the blower and water pump which ate the system cultivating the microorganism must be made as fuzzy controlization (If the sludge amount of each room become higher, the rate of operation of blower and water pump must heighten, on the contrary, in case of row sludge amount, the total handling amount and microorganism handling amount of each room of control. Tank reducing the rate of operation must be DB. At present, the blower amount in proportion to the sludge and oxygen demanding amount has to control. Each mom must be checked outlet level of the outlet, also each room must flow backward discharge materials, and must operate feed-back control until we want to be come as a below value of BOD/COD(10PPM ; KS).

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.

In a room air conditioning cooling system, if the room-sensible-heat-factor as plotted on a Psychrometric Chart intersects the saturation curve below the apparatus leaving air dewpoint, reheat must be used to maintain the design room air conditions. However, if the design room humidity is permitted to be raised to some degree, the cooling system will not require reheat as a new room-sensible-heat-factor line is developed between the apparatus leaving air dew-Point and the adjusted design room air conddition point. The advantages to this are the cost of reheat equipment and operation can be avoided. The cycle of this system can be shown on a Psychrometric Chart to plot the design condition points.

The purpose of this study was to review the operation systems and estimate the food cost of the dining room(進士食堂) in Sungkyunkwan, the highest national education institute of confucianism in the Chosun dynasty. ${\ulcorner}$the true records of the Chosun dynasty(朝鮮王朝實錄)$\lrcorner$, $\ulcorner$Taehak-Ji(太學志)$\lrcorner$ and $\ulcorner$Banjungjabyoung(泮中雜詠)$\lrcorner$were reviewed. Because the foodservices for the students were related to the Wonjeom(圓點) regulation, the qualification for the national examination(大科), Chosun dynasty government took the much considerations for the operation of the foodservice. Especially, YangHyunGo(養賢庫) was established to support the finances for Sungkyunkwan and took an important role to procure all the supplies including food. The budget of the foodservice was on a large scale. Over 960 suks(石) of rices were needed for the 200 students, and it can be converted as 276,480,000 won for the current price and the food cost per meal can be estimated about $4,000{\sim}5,000$ won.

The present study has been directed at developing thermal models to investigate the dynamic behavior of a solar cooling system including an absorption chiller, solar collectors, a hot water storage tank, a fan coil unit, and the air-conditioned space. The operation of the system was simulated for 8 hours in two different operation modes. In the mode 1, the system operated without any capacity control.0 the mode 2, an auxiliary boiler supplied heat to the generator if hot water temperature became lower than a certain value. Moreover, the mass flow rate of hot water to the generator was controlled by comparing the instantaneous room air temperature with the design value. The variation of temperature and concentration in the system components and that of heat transfer rates in the system were obtained for both modes of operation. It was found that the room temperature was maintained near the desired value in the mode 2 by supplying auxiliary heat or controlling the mass flow rate of hot water, while the deviation of room temperature was quite great in the mode 2.

Purpose: The purpose of this study was to explore the effectiveness of informational intervention delivered by electronic patient information board in the OR waiting room for reduction of anxiety of mothers with child having operation. Method: Nonequivalent control group non-synchronized design was used in this study. The subjects was 52 mothers whose children underwent elective surgery in one Pediatric Hospital. Informational intervention in this study consisted of four critical stages. State anxiety by Spielberger, mean arterial pressure, and heart rates at preoperative and postoperative period were measured. The data were analyzed by using Chi-Square test and t-test with SPSS/PC 10.0 program. Results: 1) There was a significant difference in the state anxiety between the control and the experimental groups. 2) There was no significant difference in the mean arterial pressure between the two groups. 3) There was no significant difference in the heart rate between the two groups. Conclusion: The results of this study indicate that informational intervention delivered by electronic patient information board would be an effective intervention during the operation in reducing anxiety of mothers with child having operation.
