This study examines the preliminary license and approval facilitation standards for improvements in quality for childcare centers focusing on the number of children, building space standards, facilities and equipment, and childcare program. Data from 48 caese was collected from childcare centers nationwide in Korea through a questionnaire and building plan. The first step for starting care licensing is to work out the ages and numbers of children within four or five age ranges. The second step is to work out the number of children as small, medium, or large considering staff to child ratios and building size. The Nnext step is to make a choice about childcare service quality classification as minimum, fair, or good, considering space requirements per child for the building, the classroom and the outdoor playground. The next step is to make a choice of space organization relating to service programs, considering the sleeping and eating area, indoor play area, toilet & washing facilities, classroom layouts such as cluster type, double zone type, single zone type, and others. Also, each room and entrance, office, kitchen, storage, laundry, teacher's area, and chilldren's area, need to be checked for space requirements and performances. The last step is to arrange the childcare program with the building and site plan. In conclusion childcare service quality will get better by upgrading of license regulation especially in minimum space requirements per child, corresponding with an increase in GNP and housing area per person. This is needed for childcare licensing in order to determine the quality level of childcare service.

The purpose of this study is to understand the living culture of transnational married women and to analyze the out door play of children in their hometown. The data was collected through observation from 27th June to 7th July 2008 in Jian, Jilin Province China. The children's play and lifestyles were observed, and data pertaining to the culture of the people were collected by a teacher and staff. We also visited the residents for housing information. The results are given below. 1. They dressed in Korean clothes on festive days and the boys put on a hood. They had eating habits which included cooking for themselves or buying semi-manufactured goods but did not use, instant food. The housing habits involved a combination of cooking and heating by Korean floor heating system(Ondol). They utilized outdoor space to grow vegetables. Those with a fulltime job(teacher) preferred to live in an apartment but an apartment was too expensive. Public utility charges and traffic expenses were cheap. 2. The main festive days are the lunar New Year's Day and Chuseok. The children returned home and enjoyed the festive day with their parents. The language used are Korean language and Chinese. Some Korean words and phrases in Jian Joseonjok have different meanings as compared to how they are used in Korea. A capping ceremony did not to celebrate becoming an adult from an adolescent. Couples performed a wedding ceremony at a wedding hall attended by their parents and invited relatives from both families. The relatives gave the couple a wedding gift. They did not go on a wedding trip as it was not affordable but instead spent their wedding night at a hotel in this culture. When someone dies, they bury the body after cremation. They perform a memorial service for three years on the birthday of the departed. They have a banquet on the 60th birthdays with their relatives and neighbours and are typically presented with a carp for longevity. 3. They understand capitalism and therefore send their children to school to improve their social position. The Korean and Chinese languages are required subjects in school. The students choose a second language(English or Russian). They prefer English class but at the time of this study an English class was not offered at the school in Jian Joseonjok. Therefore the children entered a Chinese school. 4. The children play outdoor games such as Y$\acute{a}$o J$\grave{i}\bar{a}$(要家), X$\grave{i}$ang g$\grave{i}$(象棋), T$\grave{i}\grave{a}$o p$\acute{i}$ j$\grave{i}$n(r)(跳皮節), D$\grave{o}$uch ing g$\grave{u}$n 凍冷根, B$\bar{e}$i B$\bar{e}$i 背背, and soccer.

This study analyzed the components contained in the pine needles of first and second-year-olds to analyze the factors that the in vivo content of inorganic elements affects the sex determination of pine trees. In response, the plan for pine tree plant and maintenance was intended to be presented in consideration of the reproductive environment and physiological characteristics. The results are as follows. First, last year, when there were many encyclopedias, the analyzed N(%) content was found to be high. The nitrogen content of the previous year's soil was found to affect the production of the spheres the following year. This is believed to be possible to reduce the rate of Pine pollen produced in the new plant in the following year through a dispute over quality consumption in the spring of the previous year. Second, the weapons elements involved in the Pine cones and the generation of the Pine pollen in the new plant appeared to be P(%), K(%), Ca(%), and Fe(%). However, the nutrients from the previous year's leaves of Ca(%) and Fe(%) were found to have a low influence on the sex determination of first-year pine trees. Because Ca(%) and Fe(%) are not able to move nutrients accumulated in aging organs due to the nature of the components, feeding nutrients in the fall when the growth of the previous year's branches is reduced is expected to affect oral generation. Third, pine trees are extremely positive and Pine pollen is related to the time of the northeast wind. Therefore, it is believed that it would be good to be located in the northern direction, where the sunlight is good, in an outdoor space. In addition, it is important to use vaginal consumer products in spring and carry out a quarrel involving Mg and Fe during fall to reduce the effect of the Pine pollen, which is an outdoor plant. This is an important part of maintaining and managing pine trees in outdoor spaces as well as the sex determination of pine trees. This study suggested that plant planning, which derives the correlation between pine inorganic element content on sexual determination and takes into account the physiological characteristics of pine trees, is an important issue in the creation of outdoor space. Follow-up research on other factors affecting pine tree sex determination is expected.

The purpose of this study is to quantify human energy budgets for different structures of outdoor spatial surfaces affecting thermal comfort, to analyze the impacts of tree shading on building energy savings, and to suggest desirable strategies of urban greenspace planning concerned. Concrete paving and grass spaces without tree shading and compacted-sand spaces with tree shading were selected to reflect archetypal compositional types for outdoor spatial materials. The study then estimated human energy budgets in static activity for the 3 space types. Major determinants of energy budgets were the presence of shading and also the albedo and temperature of base surfaces. The energy budgets for concrete paving and grass spaces without tree shading were $284\;W/m^2$ and $226\;W/m^2$, respectively, and these space types were considerably poor in thermal comfort. Therefore, it is desirable to construct outdoor resting spaces with evapotranspirational shade trees and natural materials for the base plane. Building energy savings from tree shading for the case of Daegu in the southern region were quantified using computer modeling programs and compared with a previous study for Chuncheon in the middle region. Shade trees planted to the west of a building were most effective for annual savings of heating and cooling energy. Plantings of shade trees in the south should be avoided, because they increased heating energy use with cooling energy savings low in both climate regions. A large shade tree in the west and east saved cooling energy by 1~2% across building types and regions. Based on previous studies and these results, some strategies including indicators for urban greenspace planning were suggested to improve thermal comfort of outdoor spaces and to save energy use in indoor spaces. These included thermal comfort in construction materials for outdoor spaces, building energy savings through shading, evapotranspiration and windspeed mitigation by greenspaces, and greenspace areas and volume for air-temperature reductions. In addition, this study explored the application of the strategies to greenspace-related regulations to ensure their effectiveness.

A outdoor termination installed at the outdoor substation is required to connect undergroud cables and overhead transmission lines. The joint box for AC transmission system is already developed and widely used to interconnect overhead and undergroud systems. But the development of the joint box for DC transmission system was only introduced from China and Japan, but theire developemnt staus and core technologies were not fully reported. In order to implement HVDC systems connecting ovehead transmission lines and undergroud cables, a outdoor termination should be developed, but the detailed specifications and information of this device were not reported. It is estimated that the development of the joint box for DC environment has some technical obstacles including insulating materials, electric field mitigation, thermal temperature rise, and space charge accumuations. Among this, the most important one is the DC elctrical insualtion design. Therefore, in order to investigate the DC elctrical insualton design of outdoor termination, the design of AC slip-on type outdoor termination is reffered, and DC electric field analysis performed to verify the possiblity of application of AC joint box into DC joint box. Especially for DC electric field analysis, temperature rise of insualting materials of a joint box was considered, because the conductivity of materials could be changed due to temperature rise. Furthermore, DC electric field analysis considering transinet state, and polarity reversal state were also investigated to verify which state is the most severe condition for the DC joint box. From the simualtion resulsts, it was shown that the value and the position of maximum electric field was obtained comparing AC state, DC state without temperaure rise, and DC state with temperaure rise. And it was confimred that severe DC electric field was observed considing temperaure rise. Finally, in order to reduce DC eletric field intensifation, different configuration of the joint box was applied and it was not possible to obtain satisfactory results. It means that the slight change of configuration of AC joint box was not the suitable soluton for DC joint box. It is essential to establish novel DC insulaton design skills and method for DC joint box to commercialze this product in the near future.

Light-shelf is one of the most efficient natural lighting systems due to the improved function of the inflow level of the outdoor natural light. However, the existing research on the light shelf limits to the rectangular parallelepiped space, so do not provide sufficient data for various shapes of spaces. Thus, this study aims at deriving proper plan and relationship of the light shelf through its performance assessment depending on the indoor space shapes and utilizing them as basic data of light shelf design. The conclusions are as follows : 1) for 6m space depth, standard intensity of illumination satisfaction depth has shown 8.3%~26.3% improvement through the adjustment of the angle and width when installing light shelf compared to no light shelf installation; 2) $-30^{\circ}$, $-20^{\circ}$ and $-10^{\circ}$ light shelves set by this study play only as a blind regardless of the shape of ceiling on the summer solstice, and it is unsuitable; and 3) this study has derived proper plan of light shelf upon space shapes based on energy reduction and indoor evenness. The study results provide expanded data of the performance assessment of the light shelves according to the different space shapes and light shelf factors, which serves as a basis of the light shelves designing.

In recent years, Korean population aged 65 and over has grown faster(7.2% in 2000, 14.4% projected in 2018 and 20.0% in 2026) than the other age groups and average life expectancy has increased from 65.8 years in 1980 to 75.9 years in 2000. The Aging Simulation Center(ASC) was built for people to give educational chance for further understanding of the elderly and the environment for the aged. People are able to recognize the changes including hearing loss, vision changes, and changes in the ability to touch and move after experiencing the simulated daily life of older persons. In general, ASC is composed of residential setting area and exhibition area of daily commodities for the elderly and care person. Currently, there are four ASCs in Korea. The purpose of this study is to evaluate the characteristics of space design and design elements of ASCs and to suggest design implementation for better residential environment for the elderly. For the research purpose, design characteristics such as floor plans and spatial design elements of three ASCs were analyzed and compared. As a whole, space design of three ASCs was almost same without distinguished characteristics. The major finding of this study indicates that the ASC is considerably helpful environment to understand aging. However, some of design elements such as lighting should be supplemented for safety issue. It is recommended for future design of ASC to include exterior space including outdoor stairs, paths and roads and so on. In addition, reception and preparation area should be arranged with universally designed furniture.
