The purpose of the research on the noise of educational facilities is to build up pleasant environments by minimizing the influence on the students in the school. This study provides fundamental data for acoustic design by measuring, computer simulation and analyzing the room acoustic characteristics of the lecture room in middle school. For measurement on the factors of room acoustic, RT of lecture room and noise reductions depending on various walls of different structures were measured and analyzed. The lecture system being installed and carried out on the normal lecture room was divided into 4 types-employment of multimedia machines, employment of multimedia machines and loud speakers, employment of loud speaker, and existing verbal speaking-and SPL for each type was measured and analyzed. Based on the measured characteristics of acoustic characteristics for normal lecture room, the problems for environment of noise were understood through computer simulation, applications for improvements of performance for each facility were studied, schemes for improvements of performance by using the effects were presented, necessary fundamental data were secured, and schemes to enhance flexibility on the existing facilities of school against changing educational courses were secured.

Background : 6.1% of red blood cells and whole blood issued to the operating room was not transfused to the patients and discarded in Seoul National University Hospital in 1994. Objectives : We planned to set up an effective management program of blood in the operating room and we investigated whether this program could reduce the disposal rate of blood. Methods : We made a guideline of blood management in the operating room through a workshop. The guideline was revised after a preliminary application. The revised guideline was applied for 5 months from May to September in 1996. The disposal rate was compared before and after the installation of the new program. Results : 5,336 units of blood were issued to the operating room for 5 months. Disposal rate of red blood cells and whole blood was markedly reduced from 6.2% in May to 2.1% in September(p<0.05). The average disposal rate was 3.7% during the five months. Conclusion : We were able to reduce the disposal of unused blood in the operating room through the development and the application of a new blood management program.

In this study, the reverberation time of apartment living room was measured and distribution of the reverberation time was analyzed. In addition, sound field characteristics of mock-up test room similar with living room and timber structured bedroom was investigated with addition of furniture and sound absorption material. Average reverberation time of unfurnished apartment unit was 1.11 s, and reverberation time in 630 Hz~2000 Hz bands were longer than 1.2 s. It was found that from the field measurement results, reverberation time characteristic of furnished apartment living room was uniform in most of frequency bands. Averaged reverberation time of furnished living room was 0.48 s and the reverberation time of bedroom was 0.44 s. Standardized sound pressure level correction values were calculated from the average reverberation time of furnished and unfurnished apartment units. The correction value of unfurnished living room was −3.4 dB and that of furnished living room was 0.2 dB. Measured reverberation time of furnished and unfurnished apartment units indicated that reference reverberation time; 0.5 s, in KS and ISO standards is reasonable also in Korean residential environment.

The purpose of this study is to estimate the energy expenditure of working in a clean room for manufacturing embedded needles by ergonomic programs. Embedding needle is one of medical devices and it should be manufactured in a clean room. 3D static strength prediction program was used to analyze the slow movements during embedding needle manufacturing in a clean room. Also the energy expenditure prediction program was used to estimate energy expenditure rates for materials handling tasks to help assure worker safety and health in clean room. The energy expenditures of the tasks were calculated using prediction equations derived from empirical data. The energy expenditure rate of 3.09 kcal/min in a clean room didn't exceed the 3.5 kcal/min action limit guideline for an average 8-hour day set by the National Institute for Occupational Safety and Health (NIOSH). Energy consumption was calculated on the same working conditions as EEPP program, using an average body weight of female 20 years old to 59 years who would be the candidates of the real workers.

Purpose: To find the factors of subjective musculoskeletal symptoms associated with the general characteristics and tasks of operating room nurses (OR nurses) and then to use the factors as basic information for preventing and managing musculoskeletal symptoms in OR nurses. Method: This study was an exploratory research. Data were collected using a self-report questionnaire from OR nurses working at 8 polyclinics in Korea during the period from July 26 2004 to August 19 2004. The questionnaire contains 7 questions on general characteristics and 18 questions on tasks in the operating room. Result: 187 (75.1%) nurses said they 'had' subjective musculoskeletal symptoms. Statistically significant differences were observed according to clinical career, career as an OR nurse, skillfulness, satisfaction with tasks in the operating room, perception on suitable treatment, care of symptoms by the hospital. weight of hospital linen and weight of a basic operation set (p<.05). Conclusion: Musculoskeletal symptoms complained of by OR nurses were significant. This may cause difficulties in nursing tasks in the operating room. Thus, various arrangements should be made for OR nurse with subjective musculoskeletal symptoms at the early stage.
