This study was carried out in order to establish the estimation equation for school power consumption using regression analysis based on collected power consumption for two years of weather data and schools are located in Central Changwon and Masan district in Changwon city. (1) The power consumption estimation equation for Heating and cooling is calculated using power consumption per unit volume, the difference between actual power consumption and results of estimation equations is 4.1%. (2) The power consumption estimation equation for heating load is showed 2.6% difference compared to actual power consumption in Central Changwon and is expressed 2.9% difference compared to that in Masan district. Therefore, the power consumption prediction for each school using the power consumption estimation equation is possible. (3) The power consumption estimation equation for cooling load is showed 8.0% difference compared to actual power consumption in Central Changwon and is expressed 2.9% compared to that in Masan district. As the power consumption estimation equation for cooling load is expressed difference compared to heating load, it needs to investigate influence for cooling load.

Although educational facilities are important considerations from a social equity standpoint, the educational environment generally found in rural areas has been continuously deteriorated due to numerous social problems following birth rate declines and school abolition numbers. The purpose of this study is to evaluate the commuting accessibility changed by the abolition of elementary schools. The village-level accessibility is assessed following physical accessibility criteria based on legally defined commuting distances. Moreover, this study shows the implications of commuting accessibility by school district zones through comparing the minimum commuting distances with real commuting distance. The target area is the Gangwon state, the coverage area in which for schools is the widest in South Korea (44.1 ㎢/school). We evaluated the commuting distances to the nearest elementary school for 992 rural villages and 74 urban villages. Of the 1,066 villages in urban and rural areas evaluated, most of the villages (about 77%) are exposed to commutes to elementary schools were the marginal distance is over 1,000 meters. The annual rate of increase of commuting distance for 1,066 villages in Gangwon state has steadily increased by 2.8%p since 2000, average commuting distance from 2.8 km to 3.6 km. By the designation of the school districts, elementary school students have to go to a faraway school located within administrative district, even though there is a school nearby. It is expected that the results of this study will be made use of as basic data for the establishment of policies such as a reasonable basis for closing schools measurements considering the locally unique environment.

This study discusses an effort to build a model to link normalized difference vegetation indices (NDVI) and socio-economic indicators derived from village survey (1990, 1993, 1996, and 2000) statistical data in Bekasi, West Java, Indonesia. Socio-economics indicators of sub-district level, in this study the number of agricultural households (AH), are aggregated from village level data. NDVI from Landsat-TM resolution data (1989 and 1997) are computed to detect land use/land cover (LULC) dynamics in the sub-district areas. Attention is mainly paid on the examination of agricultural land cover changing in the sub-district level. NDVI measurements might be used to predict AH dynamics as showed by computed linear regression models.

경동시장 한약상가는 조선시대부터 한약의 중심지이던 종로 4,5,6가 일대 한약상이 1960년대부터 이쪽으로 이동하기 시작하면서 발달하였다. 이 상가는 편리한 교통을 바탕으로 한약도매상의 성격을 띠면서 성장했다. 한약상가 내에는 다양한 한방관련 업종이 분포하고 있다. 최초 연구를 수행했던 1994년 당시에는 한의원이 주를 이루었으나 2007년에는 도매 중심의 한약국이 한의원을 대체하는 현상이 현저해졌다. 여기에는 한의사의 노령화가 크게 관여하였다. 경동시장 한약상가는 전국 약재물동량의 70%를 점유하고 있으며, 이 가운데의 70% 정도가 외국산이다. 과거에 비해 현대화된 건물이 속속 들어서 한약상가의 외관과 규모는 발전하였지만 실제 상황은 활기를 띠지 못하고 있는 형편이다. 본 연구의 목적은 1994년부터 2007년까지 13년간의 변화상을 고찰하고, 변화의 주된 원인을 규명하고자 하였다. 그간 경동시장 한약상가는 현대화된 모습으로 변모하였으나 새로 들어선 한방건물의 영업 실패의 주된 이유를 '장소에 대한 관성'이라는 개념으로 설명했다. 경동시장 한약상가는 우리나라의 전반적인 경기침체와 맞물려 어려움을 겪고 있지만 한방특구로 지정되면서 세계 최대 규모의 한약상가로서, 새로운 관광자원으로서 발돋움하려는 노력을 지속하고 있다.

This retrospective study was designed to evaluate the nutrient contributions of the five meal components of school lunch menus planned for elementary students in two school districts (District A and B) in the Midwestern state of the United States. The 4-week cycle menu was planned for two time periods (Period 1 and Period 2) following guidelines for NuMenus and general menu planning principles. Menu components of planned and served menus for two time periods were analyzed using $Nutri-Kids^{TM}$. No significant differences in the nutrient content of between Periods 1 and 2 were found for District A. District B served significantly more vitamin A and total fat in Period 1 and significantly more calories, iron, vitamin A, protein, and total fat in Period 2 than was planned. The major nutrients provided by the entree component included protein, calories, cholesterol, total fat, saturated fat, and sodium. Milk was an important source of calcium and provided approximately one-third of the total protein and vitamin A in the meal. The vegetable/fruit component was the major source of vitamins A and C. The grain/bread component provided approximately 20% of the carbohydrates among five meal components. The miscellaneous component affected the sodium and fat content of the menus. Menu planners can use the results of this study to enhance their knowledge of the nutrient contributions of each meal component and as inputs for planning menus that meet children's nutritional requirements.

Under the guise of a residential environment improvement, distendedly designated Pre-Housing Renewal districts and Renewal Districts by Basic Plan for Renewal Projects are not promoted and leaved for a long-term so that residential problems have become worse. In case of the canceled Housing Renewal district, at the time when the district are canceled, the residential environment has become already superannuated for more than 10 years but there is no follow-up plan to manage that problem so that the exact management plan for those neglected districts is urgently needed. Therefore, the purpose of this study is to analyze the aspect of change of residential environment after the cancellation and indicate appearing problems by conducting on the case of Canceled districts of Daegu Housing Renewal District. This study will be the first step to seek practical management measures for canceled districts, and on the basis of this, the research will become a precedent to seek the sustainable planning measures for the designation and management of Renewal Projects from now on.
