Medical radiation offers significant benefits in diagnosing and treating patients, but it also generates unnecessary radiation exposure to those nearby. Accordingly, the objective of the present study was to analyze spatial dose rate according to types of radiation source term in multi-bed hospital rooms occupied by patients and general public. MCNPX was used for geometric simulation of multi-bed hospital rooms and radiation source terms, while the radiation source terms were established as whole body bone scan patients and imaging using a portable X-ray generator. The results of simulation on whole body bone scan patients showed $3.46{\mu}Sv/hr$ to another patient position, while experimental results on imaging using a portable X-ray generator showed $1.47{\times}10^{-8}{\mu}Sv/irradiation$ to another patient position in chest imaging and $2.97{\times}10^{-8}{\mu}Sv/irradiation$ to another patient position in abdomen imaging. Multi-bed hospital room, unnecessary radiation generated in the surrounding patients, while legal regulations and systematic measures are needed for radiation exposure in multi-bed hospital rooms that are currently lacking in Korea.

The aim of this study was to investigate the trend of the room where activities of daily living and family rituals(activities of non-daily living) were performed between 1992 and 2002. Research data was collected in 1992 and 2002 from households living in Seoul that have university student by using questionnaire surveys. Data was analyzed using the SPSS package program. The major findings of this study were as follows: 1) Living room was a multi-function space for various activities: receiving guests, family communication, ironing, sewing and dining as well as a kitchen. Anbang(master bed room) is the place where the couple sleeps. Anbang's function has changed from a multi-function space to a private space. 2) Most of the families performed the majority of the family rituals in the living room and Anbang. In 1992, traditional events and birthday parties were performed in Anbang, but in 2002, the trend has changed. This would mean that with time the majority of the family rituals were held in the living room. 3) Space planning is required to meet the dwellers' use of living room and Anbang.

The purpose of this study was to investigate the trend of the room where activities of daily living and family events(activities of non-daily living) were performed with time. Research data was collected in 1992 and 2002 from households living in Seoul that have university student by using questionnaire surveys. Data was analyzed using the SPSS package program. The major findings of this study were as follows: 1) Living room was a multi-purpose space for various activities: receiving guests, family communication, ironing, sewing and dining as well as a kitchen. Anbang(master bed room) is the place where the couple sleeps. The room's purpose has changed from a multi-purpose space to a private space. 2) Most of the families performed the majority of the family events in the living room and Anbang. In the past, traditional events and birthday parties were performed in Anbang, but currently the trend has changed. This would mean that with time the majority of the family events were held in the living room. 3) Space planning is required to meet the dwellers' use of living room and Anbang.

The purpose of this study was to explore behaviors of spatial usages such as patterns of spatial usages, perception on residential spaces, and furniture arrangement. A questionnaire survey and interview were adopted in this study, and 146 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Gwangju. The major findings of this study were that 1) dining-kitchen (DK) was conceived and used as a space not only for dining but also family gathering and guest reception. Dining table without refrigerator was frequently found in furniture arrangement of DK, and refrigerator has been relocated in utility room facing DK. The results imply the need for social interaction that has been growing. Anbang (master bedroom) has been perceived and used as couples' private area, aside from the traditional function of family interaction. A coordination of both bed and wardrobe out of different furniture arrangements was popular in anbang. Living room was used as a multi-purpose room carrying out various activities such as family gathering, guest reception, and housekeeping. Sofa and cabinet were the most common furniture arrangement in living room. The research results are a basis for development residential open housing system.

The effects and necessity of the breast milk are well known, but the breast-feeding rate in our country is very low. One of the reason is due to the separation policy of mother and baby after delivery. The mother is in the inpatient-room and the baby is in the new-born baby room. This isolation operation of hospital get increased according to the decreasing ratio of breast feeding in Korea. Only a few hospital operates and provides the space for a new-born baby in the mother's room. The system of baby and mother in one room is adopted and operated due to the breast feeding campaign. It is very encouraging, but the space for the baby and the mother is not enough in multi-bed rooms. We should reconsider the relationship between the new-born baby unit and the obstetric ward, and design the patient's room for the baby and the mother.

Additive manufacturing with 3XX austenitic stainless steels has been widely investigated during a decade due to its high strength, good corrosion resistance, and fair weldability. However, in recently, Ni price drastically increased due to the high demand of secondary battery for electric mobilities. Thus, it is essential to substitute the Ni with Mn for reducing stainless steels price. Meanwhile, the chemical composition changes in stainless steels not only affect to its properties but also change the optimal processing parameters during additive manufacturing. Therefore, it is necessary to optimize the processing parameters of each alloy for obtaining high-quality product using additive manufacturing. After processing optimization, mechanical properties and microstructure of the laser-powder bed fusion processed Fe-15Cr-7Ni-3Mn alloy were investigated in both room (298 K) and cryogenic (77 K) temperatures. Since the temperature reduction affects to the deformation mechanism transition, multi-scale microstructural characterization technique was conducted to reveal the deformation mechanism of each sample.

This study aims to identify convenient surrounding of the hospital room to be improved by specifically focusing on light environment and to examine a change of inflow of the daylight in the hospital room by using blind and light shelf device as base data of preliminary research for comprehending the relationship between healing environment and natural day light. Simulation analysis on previous facilities and the installation of horizontal light shelf that derives the inflow of day light has been specifically referred by using ECOTECT2011 program. In case of C-facility that mostly adjoined to exterior spaces, it was shown to be closer to a proper uniformity factor when an angle was controlled on the light shelf with blind installed at the same time. However, it was not overall appropriate because of visual displeasure occurred from inflow of much day light. In conclusion, it is the form of flat surface such as H-facility that provides an effect after installing the device to derive day light. Especially, it was shown that interior day light environment was improved when installing blind and controlling the angle at the same time.
