This study mainly examined the unit space (room) called 'MARI' of the private houses that were built between the 19c and the early 20c in the insular areas of southwestern sea. Generally, this region has unique historicity (restructure of the insular environment in the 17c and the 18c) and geographic environment that are different from inland regions thus the environment is presumed as a related factor to developments and structures of the private houses. 'MARI' is a noticeable space that is installed in a main building without an exception even in small 3 bedroom private houses. Its nature has location and usage distinctions in an architectural plan with similar 'MARU' of inland Jeollanam-Do. There are large crocks filled with grains at MARI. Thus, MARI is a storage room. Mostly rice and various other kinds of grains are stored in the several crocks, large and small. Many household goods are kept here as well. Another peculiar function of MARI is that this space commonly enshrines ancestral tablets of three generations. Hence, MARI takes a role of a shrine of an aristocratic house from an inland region. Considering the size of the house and space, this seems to be a very unprecedented utilization of area. MARI is located at the top (at the head of the house) on the floor plan. In other words, it is located at the space in the highest rank. The importance of ancestor worship and grains is evinced architecturally. It is really interesting fact that MARI is also located within recently built modern houses (Cheongsan Island, Joyak Island, etc.). Therefore, it can be said that the unique MARI tradition of this region has an intact continuity even today. After all, MARI has a great significance as a unique unit space of insular areas of southwestern sea that is installed in the main buildings of all houses regardless of size and shape of the houses, and their insular locations.

Purpose: The main objective of this paper is, to assess environment, care process, and patient-related factors associated with patient falls. The study also aims at identifying various factors that would affect inpatient falls and, therefore, helping both caregivers and designers contribute to better prevent inpatient falls in their own areas of expertise. Methods: A retrospective analysis of inpatient falls that occurred in the unit of General Medicine in the United States has been conducted and environment, care process, patient-related factors associated with those falls have been analyzed at the same time. Results: The study identified several factors associated with inpatient falls. They range from environmental factors to care process- and patient-related factors. Patient visibility and patient accessibility can matter to patient falls and where those falls occur, along with patient days per room, the percentage of patient days with high fall risk patients per room, the percentage of high fall risk patients per room. Implications: The findings of the study can provide design implications that can be incorporated into design process and design decisions to promote fall prevention in inpatient care units. Inpatient falls can be effectively reduced when caregivers and designers work together to understand the complex nature of inpatient falls and the importance of multidisplinary efforts among various experts in the areas of healthcare.

The purpose of this study was to determine if homogeneity of the resin associated with benchcuring could be obtained in the curing unit as the water increased from room temperature to curing temperature. The results of the experiment were as follows : 1. Long periods of bench-curing are not necessary. 2. Bench-curing can take place in the water bath of the curing unit. When this procedure is used, the water should be far enough below the temerature at which active polymerization of the resin proceeds to allow the bench-curing to occur.

We performed the experimental and the numerical study on the comparison of thermal comfort performance indices for cooling loads in the lecture room for 4 cases: Fan coil unit(FCU) or 4-way cassette air-conditioner is respectively operated with the ventilation system or without. We measured the velocity, the temperature distribution and predicted mean vote(PMV) value in the lecture room for 4 different air-conditioning methods. Effective draft temperature(EDT) and PMV were investigated to analyze the characteristics of two thermal comfort indices in the lecture room and to compare their values each other. From the results we knew that there is the similarity between PMV values and EDTs when the room is air-conditioned for cooling loads. It turned out that definition of the control temperature is very important when the EDT is calculated. Finally EDT should not be used to predict the accurate thermal comfort in case that the temperature and humidity are suddenly varied and the zone affected by the solar and inner wall radiation.

This experiment was carried out to investigate the changes of egg qualify during storage in order to find out the proper storage condition. Fresh eggs were stored at cold condition ($5^{\circ}C$, relative humidity ; RH :$65\pm$3%) and room condition($25^{\circ}C$, RH :$40\pm$3%) during 10 weeks and examined microbiological quality, weight loss and interior quality periodically. Weight loss was indicated 17.93% at room condition and 2.56% at cold condition. The pH of egg white and yolk were increased from 7.94 to 9.03(average 13.72%) and from 6.16 to 6.57(average 6.65%) at cold condition and from 7.94 to 9.54(average 20.15%) and from 6.16 to 6.90(average 12.01%) at room condition respectively. But pH of egg white and yolk did not showed significant difference between before molting and after molting. Haugh unit was decreased from 82.0 to <30 at room condition after 3 weeks. The most frequent bacteria isolated were E coli, Staphylococcus leutus, S saprophyticus, Citrobacter freundii, Klebsiella oxytoca, Providencia rettgeri, and Pontoea spp. It was recommended that shelf life of unrefrigerated eggs would not be longer than 21 days at room temperature in summer.

The purpose of this paper is to describe the transition of a 1,100 beds teritary hospital from 50% softcopy operation to full PACS operation. For the past 2 years, radiologists and clinicians have been using PACS to provide softcopy services to the outpatient clinics and inpatient wards of orthopedics surgery, neurosurgery and neurology as well as emergency room, surgical intensive care unit, medical intensive unit, pediatrics intensive care unit and neonatal intensive care unit. The examinations requested by these departments account for about 50% of hospital's radiological exams. In September 1996, we began the second phase of PACS implementation and installed additional workstations (102) in the remaining wards and clinics, interfaced to PACS additional imaging modalites, and increased the capacity of both the image server (256 Gbytes) and optical juke boxes (3 Tbytes). As of January 1997, we are in the final phase of moving away from conventional film system to full PACS operation.
