The air ventilation system of operation rooms has been studied to prevent the cross infection during the operation. Operation rooms and air ventilation systems of three University hospitals were investigated. The distribution of microbe was measured by cultivating air samples in the operation room. A two-dimensional model for the cross-section of an operation room was developed for the CFD(Computational Fluid Dynamics) analysis. The characteristics of air flow in the empty operation room and in occupied operation room were calculated by using a CFD program. The current diffuser location of an old hospital did not deliver the clean air to the operation part efficiently. A new method to locate diffusers that improve air venting with little increase of the cost of equipment was suggested.

Recently, multi-room type heat pump system has aroused much attention, because it can achieve much reduction of installation cost and space as well as energy saving in companion with the single room type heat pump system. In the present study, performance characteristics of a 3 room type inverter driven heat pump system, which is widely spread in Japanese market, are measured.. In the single room operation, performances of a heat pump system such s the difference of compressor outlet and inlet pressures and the mass flowrate may increase with the increase of cooling capacity so that COP of the system decrease with the increase of cooling capacity. However, in the 2 room operation, mass flowrate and COP of the total system increase markedly as compared with the single room operation.

To minimize the train operation interruptions and train exchanges, the RF transmission system is proposed. The current control room of the Seoul Metro has information of the train movement through the Total Traffic Control System, but it does not have information of the train itself, rail status, and other facilities' status. When some trouble occurs during train operation, the train crews should report the control room about the trouble and fix it. If the control room has exact information of the trouble, the expert in the control room can help the crews to fix the trouble swiftly and exactly. Since the crews are busy taking care of the trouble, they often miss to report the control room on time. The proposed RF transmission system relays the information of the train to the control room automatically in real time, and makes it possible to provide the passengers good service by reducing the train operation interruptions and train exchanges.

Objectives: The purpose of the study is to investigate the parents' toothbrushing guidance on the children by operation of toothbrushing room. Methods: A self-reported questionnaire was completed by 790 parents of first, fourth, and sixth grade students of J elementary school in Changwon from June 1 to 30, 2013. J elementary school did not have toothbrushing room. The questionnaire consisted of general characteristics of the subjects (3 items), toothbrushing room operation (3 items), and toothbrushing (7 items). Data were analyzed using SPSS 20.0 program. Results: Parents of high school diploma demanded the establishment of toothbrushing room (p<0.05) and parents having undergraduate course tended to want the operation of toothbrushing room (p<0.05) and children's dental health care (p<0.05). Parents within forties tended to have higher concern for their children's toothbrushing (p<0.05) and toothbrushing room operation (p<0.05). They tried to have much interest in their dental health checkup and toothbrushing frequency. Conclusions: The establishment and operation of toothbrushing room is very important to elementary school children. The toothbrushing guidance by parents will enhance children's dental health knowledge and maintain lifelong dental healthcare for the children.

Purpose: The purpose of this study was to perform an operating room nursing activities analysis and estimate nursing intensity of each nursing activity based on the Relative Value Scale (RVS). Methods: The methodology for this study of RVS was based on the work of Hsiao et al. The first stage was to identify nursing activities and the second to measure intensity of nursing activities including technical skill, mental effort, and stress. Results: Calculation of the RVS for 99 nursing practices showed a score range from 300.00 to 1337.78. CS operation assistant, OS operation assistant, and obtaining certification had high nursing intensity. Surgical hand washing, putting on surgical gowns, surgical gloves and surgical caps and mask had low nursing intensity. Conclusion: The activities of operating room are not compensated separately but reimbursement is usually included in physician fees. In the future, an estimation of nursing cost should show the nursing contribution rate to total operation revenue.

Background : This study was attempted to provide a basic information necessary for the development of measures evaluating perceived discomfort of the patients under local anesthesia and the developments of nursing intervention and nursing standard. Method : The study subjects were a convenience sample of 100 surgical patients under local anesthesia. The researcher visited the patients directly and explained the purpose of the study to them. Then they were asked to fill out questionnaires which were developed and structured by the researcher, under their prior permission. Out patient's data were collected at recovery room after operation. Results : Factor analysis on measures evaluating the patients under local anesthesia showed that the measures consisted of eight factors including "explanation", "humane treatment", "motion limitation", "pain", "no togetherness", "waiting", "the environment of operating room", and "unkindness". When analyzing each of the factors regarding their degree of contribution to perceived discomfort, it was found that "waiting" was highest in terms of the degree. According to general chara-cteristics of the sampled patients, the factor of "explanation" contributed to perceived discomfort more in male patients than female ones. Regarding parts of medical examination, the patients of otorhinolaryngology felt perceived discomfort most because of the factor of "pain". Conclusion : To relieve perceived discomfort the patients under local anesthesia require providing individually systematized nursing services which can reduce perceived discomfort according to each of the factors. In doing so, an unlimited attention and much effort should be given to realize CQI reaching the dimension of increase in comfort as well as decrease perceived discomfort.

In this study, the operation strategy of the radiant floor cooling is evaluated in terms of indoor environmental conditions and energy consumption through simulations using the TRNSYS comparing the existing cooling operation. The operation strategy during continuously operated for cooling is proposed that a representative room had additional equipments and other rooms were operated with only a radiant floor cooling system and that system and control method for cooling are varied with period while intermittently operated for cooling. Specifically, when there are no people in the room, rooms were operated by only radiant floor cooling system using cooling storage and when people are occupied, rooms were operated by dehumidification and supplementary cooling device with radiant floor cooling system. The results of this study show that proposed operation strategy can stably maintain the set room air temperature and can reduce the energy consumption compared to the existing cooling method during continuously operated for cooling. While intermittently operated for cooling, the difference of set room air temperature by proposed operation strategy does not happen, satisfying comfort standards and the radiant floor cooling can expect to supply stable electric power because of decreasing demand for peak electric power of energy consumption.
