Nowadays, Korean society is quickly transforming into an aging society. There are lots of problems resulting from old aged society. First of all, in the case of medical service, it is an urgent task to find out what is the most proper care for the elderly in order to reduce medical expenses. It can be said that the geriatric hospital has to be designed to give adequate medical service to the elderly. However, it is hard to find out what the differences is between the general hospital and the geriatric hospital. Especially, the plan of the patient room has to reflect thoughtful consideration relating to characteristics of the elderly due to the fact that there is a close connection between the patient room and residence. Therefore this study aims to suggest the guideline and the plan of the patient room for the elderly.

Purpose: The purpose of this study was to develop the medical error reporting system and to validate an trait of error in the Operating Room. Methods: Descriptive research design was used. The subjects were 30 nurses with below 5-year-career in a University Hospital. Data was collected from 11, April until 22, April, 2005 using web-based error reporting system. Data was analyzed by mean, standard deviation, $X^{2}-test$ using SPSS WIN 10.0 program. Results: A time of medical error in operating room nursing frequent occurrence was from 12 pm. to 4pm. 'Lack of sterile materials' management' was the best frequent occurrence of medical error in operating room nursing. Conclusion: The findings of this study show that manager of healthcare organization must develop the error reporting system more familiar and ordinary. Afterward, we prevent the repetitive medical errors in nursing care through analyzing of error reporting system.

It is known that elimination of ship engine room noise is impossible thing, so the working environment in the engine room is getting worse because ships are recently built with huge engines to take higher sailing power. In the yacht and cruise yacht, the engine room noise is more serious because they have bigger engines relative to their hull sizes. The noise generated from the main engine makes the employee to hearing loss and the transmitted noise make the uncomfortable conditions in the cabins of ship. The noise generated by ship engine must be attenuate for the employee and passenger. In yacht and cruise yacht, the noise levels in cabines are the most important criterions to the value of commodities. In this study, the noise absorbtion barrier which have resonators is experimentally studied by the 1/3 octave band noise elimination rates(%).

In general, the function of university dormitory includes residental, educational and many other functions for students who need quite environment and energetic living life. Among these many functions, the most important function is residental function (bed room). This study attempts to evaluate the bed room environment of four university dormitories in north region of Gyeongbuk Province using resident's (students) need and satisfaction. In the present work, SPSS window version12.0 program's Anova (duncan, scheff, t-test.) was used for analysis of statistical data which obtained from survey. The field surveys carried out for a total samples of 473 residents such as AD (118), DY (159), Kw (101) and SJ (95)) types of bed room in four university dormitories. The result appears that the most dissatisfied factor of resident was personal privacy, and the most satisfied factor was the direction (location) of bed room space.

In this study, develop the thermal pump using water evaporation and condensation. Vapor from heating room moves up to pumping room and press the water of pumping room. Consequently water is pumped out to water tank. Then hot vapor direct contact with cold water in condensing room after pumping process. At this time, pressure of condensing room is down to-5kPa and suck in water of tank. This pump executes self ping and good durability because of no mechanical moving parts. Thermal pump is pumped cyclic so that, this pump is not used single. Therefore thermal pump of hot water boiler used to multi-stage for stable pumping rate. As the result of performance test, the developed thermal pump proves pumping action of water evaporation/condensation. And total volume flow rate is 500liter during one hour. If three thermal pump is installed parallel, this pump can use to the hot water boiler in the 300,000kcal/h class.

Indoor air environment is one of the most important factors that affect resident's health and comfort level. In this paper, the influence of ventilation efficiency with different types of furniture arrangement at breathing zone in a room was analyzed by numerical simulation based on computational fluid dynamics(CFD). The furniture layout of students' bedroom have been classified by three different patterns so that SVE3(scale for ventilation efficiency3) in the rooms was analyzed for air flow distribution. According to the results of the study, SVE3 has the maximum value in spaces between furnitures and each comer of the room. The furniture arrangement influences the ventilation efficiency. It was con finned that ventilation effective in a room is not uniformly distributed as compared the breathing zone with all the area in a room. It means that a study of ventilation efficiency was considered relatively with target zone(a residential or breathing zone) and all the area in a space.

The heavy thermal load to battle tanks can cause electronic components' malfunction and crew to be put out of action. The thermal load is generated from Internal heat sources such as electronic devices installed in the room as well as extremely hot weather. In this study, heat and flow analysis for the cabin room of a battle tank was performed to deal with this thermal problem. This study presented the validation of simulation results in comparison with those of test, the investigation of optimal flow design for effective cooling in cabin room and finally the evaluation of thermal comforts to crew.

This study aims to analyzed the acoustics characteristics of Korean Traditional Houses in Chonnam Province varied with lay out and floor plane to reflect the way of control for environmental condition. These houses are surveyed the reverberation time and level difference between rooms of the main living room and other main floored room, master room and kitchen. As a result, the reverberation time of traditional rooms are below 0.6 second, and the sound insulation performance of Korean traditional door are mostly very low grade with D-15. The level difference between rooms are low grade not to meet minimum class except between main living room and master room away from main living building.

Purpose:The purpose of this study was to apply the disinfection method using chlorhexidine in practice on disinfection of vascular access for hemodialysis. Methods: This study was designed as a randomized controlled trial for examining effectiveness on infection of the vascular access device for hemodialysis when using chlorhexidine and betadine/alcohol. One-hundred-thirty study participants were separated into two groups randomly. Infection signs of the vascular access device for hemodialysis were observed and recorded before disinfection on vascular access device. Result: Before the study, there was no difference between the experimental group (chlorhexidine group) and the control group (betadine/alcohol group) in general characteristics and hematological index. Incidence of infection rate of chlorhexidine group was 0 percent and the betadine/alcohol group was 1.5 percent. There was no significant difference between the two groups. Conclusion: This study examined the effectiveness of prevention of infection with the disinfection method using chlorhexidine and betadine/alcohol. The disinfection method using chlorhexidine is considered an effective and alternative method of betadine/alcohol.
