Recently, the long-term care insurance for the elderly was carried out according to the elderly is increased rapidly and the formation of sympathy that a nation and society try commonly to share health and welfare promotion of the elderly. The purpose of this study is to analyze the present status of nursing home after that the long-term care insurance is enforced in chungcheongbuk-do and to utilize as basic data. The study limited its survey to those facilities that refer to the Ministry of Health and Welfare data, that had the capacity of more than 50 people. The result are as followings. Firstly, most of the nursing home were located on the outskirts of the city. But it must be constructed in the city center if the recent deinstitutionalization trend is reflected. Secondly, notwithstanding the provisions of the Elderly Welfare Law, if the Livability and amenity are considered, the plan of a single or a twin room is needed. The ondol(溫突) system bedroom for the safety of the elderly had to be planned and for the color planning of a bedroom, a heating, the furniture, the form of a door, corridors, etc. should be partly improved. The fastener in which it is appropriate for the main exit, a stair, an elevator, the lighting device, and etc. is needed and the installation of a wandering path for the dementia patient and etc. is required. Thirdly, most of the dining room arranged on the first floor but it is not nearly used and it used for employee or the other use. Therefore, we have to consider the system in which it can deliver the meal to a bedroom. If the smell of the elderly and etc. is considered, the sufficient height of the floor should be reflected for the ventilation equipment. Lastly, The improvement of the existing law are required.

The purpose of this study is to determine the personalizing characteristics of detached housing that reflect the housing needs according to the residents' participation in the back-to-countryside community village. For this study, 15 households of Jagun-maul at Namwon in Jeonbuk provided responses to the semi-structured questionnaire on housing consciousness, housing needs, and views on lifestyle. In addition, 15 plans were analyzed about the shape of the plan, the composition of LDK, the type of access, and the type of special space. The results were as follows. 1) The number of households under the elementary education stage was larger than the number of households above the middle education stage. Most of the households revealed the housing consciousness of 'house as resting place'. Households under the elementary education stage showed a housing consciousness for family-oriented life and households above the middle education stage showed a housing consciousness to interact with neighbors. 2) Households under the elementary education stage preferred LK style while households above the middle education stage preferred LDK style. Most of the floor plans had a front entrance and sliding door for the access from living room to garden. 3) Special spaces such as a loft, 'Ondolbang' (room with underfloor heating), study, maru, 'Toenmaru' (narrow wooden porch), family room, workroom, and toilet with outside door were arranged on each floor plan.

Korea has achieved a rapid economic development and with the increase in population and national income and the expansion of social and economic activities, energy consumption has rapidly increased too. Energy consumption per head has constantly increased and currently, power consumption per head is 7.5 times bigger than in 1985. Buildings occupy 25% of total energy consumption and especially, 50% of total energy is consumed for heating and cooling. In this situation, multi-family housing, which has constantly been increased, has an energy saving rate of 1.9%, which is the lowest level and this makes the government's energy policy for sustainable energy system development useless. Besides, energy consumption leads to secondary problems, such as air, water and marine pollution and heat pollution and wastewater/drainage and the increased use of fossil fuel is a fundamental reason for ozone layer destruction and global warming. Therefore, efficient energy consumption plans are required. This study aims to analyze energy performance in each block type of high-rise and diversified multi-family housing that accounts for 60% of all the housing forms, depending on the variations in stories through BIM-based energy simulation. For this study, four representative block types were selected, based on the multi-family floor plan, which is certified for energy performance evaluation and they were applied to the floor plan of a multi-family house that is scheduled to be built. Then BIM modeling was conducted from the fifth story to the 40th story at an intervals of 5 stories and based on the finding, energy characteristics of each block type and energy performance depending on the variations in stories were analyzed. It is considered that this would serve as objective data for block type and block story decision of energy performance-based multi-family housing.

Introduced in 2004 as an 'After-School Academy' policy, the 'After-School Care Class' has become a universal program for elementary schools over time. While the concept of public education service has expanded and changed in various ways including educational welfare, the physical environment of the care classroom has undergone fixed changes within the uniform classroom structure of a standardized school space. The purpose of this study is to identify spatial characteristics of care classroom through chasing and analysing changes in the care class space configuration from 2004 to the present. The findings are as follows. The plan of the early care classroom wasn't much different from the existing common classroom, and it was only in 2007 that the kitchen and floor heating appeared for the first time.From the 2015 standard plan, prominent differentiation of the space between learning activities and resting area was shown, but the spatial characteristics are nothing more than a division that utilizes ready-made furniture. A distinctive feature of the 2018 Seoul care classes are diversity. In the case of the care exclusive classrooms, the division between the support space and the main activity space became more clear using furniture integrated open walls and various floor levels. In the case of a shift classrooms that is used together with common classrooms, it is characterized by flexibility that allows dramatically different classroom configurations for each time period by using a convertible furnishing space.

This paper aims to approach a spatial furniture for sedentary lifestyle which been has derived and evolved from Korea's traditional 'Ondol' heating system. In this living culture, people has been staid on the floor where people would sit directly on without furniture such as chair and bed. With every changing technological advances, sedentary life culture is transformed and mixed instead of sedentary habit. Most of people lived in western house such as apartment forms. As time go by, western furnitures were used became widespread. However, during the process, it impossible to acclimate ourselves to the new lifestyle such as chair, bed etc. This leads to users feeling uncomfortable on certain points. The researcher suggests a spatial furniture through a new approach to rest-taking that also intersects the cultures of East and West while resolving the a fore-mentioned issues. The study is conducted as follows. Firstly, issues are discovered through a user's lifestyle to exist usage and interplay of house and furniture. Furthermore, the issues was not a fragmentary thing but more related to a culture and a coustom of long standing. Secondly, a design experiment is conducted to conclude a new form and function that is better fit for the Korean culture where sitting on the floor is the norm. New direction for space that intersects the cultures of the East and West while using modules made convenient for contemporary life is presented. Finally, this study is meaningful in that it reinterprets furniture used for rest within the context of sedentary culture, in order to propose a new direction and value for design that overcomes the boundaries between eastern and western applied to resting space.

It is important to design windows in a reasonable way considering the performance characteristics of the elements of the window rather than just to increase the thermal energy performance of the window. In this study, the Heat-transfer Coefficient as insulation performance of the windows and together with the grade of the glass's SHGC (Solar Heat Gain Coefficient) were analyzed to relate to the energy efficiency performance of the building by azimuth angle. Based on this basic study, the Heat-transfer Coefficient of windows and the SHGC rating of glass were applied to the unit plan of apartment building, and the Heating and Cooling Demand were analyzed by azimuth angle. Apartment plan types were divided into 2 types of Non-extension and extension of balcony. The designPH analysis data derived from the variant of the Heat-transfer Coefficient and SHGC, were put into PHPP(Passive House Planning Package) to analyze precisely the energy efficiency(Heating and Cooling Demands) of the building by azimuth angle. In addition, assuming the 'ㅁ' shape layout, energy efficiency performance and potential of PV Panel installation also were analyzed by floors and azimuth angle, reflecting the shading effects by surrounding buildings. As the results of the study, the effect of Heat Gain by SHGC was greater than Heat Loss due to the Heat-transfer Coefficient. So it is more effective to increase SHGC to satisfy the same Heating Demand, and increasing SHGC made possible to design windows with low Heat-transfer Coefficient. It was also revealed that the difference in annual Heating and Cooling Demands between the low, mid and high floor households is significantly high. In addition to it, the installation of PV Panel in the form of a shading canopy over the window reduces the Cooling Load while at the same time producing electricity, and also confirmed that absolute thermal energy efficiency could not be maximized without controlling the thermal bridge and ventilation problems as important heat loss factors.

Background Various focal heating devices are popular in Korea under the cultural influence of the traditional ondol under-floor method of home heating. These devices can cause severe burn-like injuries resulting from device malfunction or extended with low heat contact. In addition to injuries under these high heat contact, burns can be occurred by low heat exposure with prolonged periods despite the devices are properly functioning. In order to develop strategies to reduce the duration of periods of illness due to low-temperature burns, we analyzed and compared treatment methods and therapeutic periods for this type of injury. Methods This retrospective study included 43 patients burned under low heat conditions. Patients were divided into an operative group and a conservative group. The patients in the operative group underwent at least one surgical excision, and were further subdivided into early and late visit groups. The conservative group was treated only with dressings. We compared the treatment periods between the operative group and the conservative group, and also compared the preparation periods and treatment periods between the two operative groups. Results The average treatment period was significantly shorter in the operative group (P=0.02). In the early visit operative group, both wound preparation and treatment were briefer than in the late visit group. Conclusions We recommend that early proper burn care and early surgical intervention, including appropriate excision, are feasible ways to reduce the treatment period of lowtemperature burn patients.
