김병량,김수철,손인진,Kim, Byung-Ryang,Kim, Su-Chul,Shon, In-Jin 한국분말야금학회 2009 한국분말재료학회지 (KPMI) Vol.16 No.1

Nanostructured $ReSi_{1.75}$ was synthesized to have high density via rapid and cost effective process named as high-frequency induction heated combustion synthesis(HFIHCS) method. For the process, mechanically activated Re-Si powder was used, which had been prepared by mechanical ball milling of Re and Si powders with mixing ratio of 1:1.75. Both combustion synthesis and densification were accomplished simultaneously by applying electric current and mechanical pressure of 80 MPa during the process. The average grain size, hardness, and fracture toughness of the compound were 210 nm, 1085 $kg/mm^2$ and 4 $MPa{\cdot}m^{1/2}$, respectively. The experimental results show that HFIHCS is a promising process for synthesis of nanostructured $ReSi_{1.75}$ which has a potential for both high temperature and thermo-electric applications.

1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is looking up the efficient way of developments of commercial properties, and sales. Especially this study concentrate on supply such as oversupply, or shortage to prevent operation houses, and delayed leases, shortage of social overhead capital. By analysing the condition of a location, and features of store's location, this study would like to offer one of the index of commercial properties' planning, for instance, size, location by floor. (2) RESEARCH METHOD This study did actual analyze type of businesses, ratio of area for exclusive use, location floor, and rental fee from thirty-three different Residential land development district to figure out locational pattern, and features. By comparing and analysing the elements, This study find out the locational floor patterns, and location features. SPSS 17.0 used to analyze. (3) RESEARCH FINDINGS In the results of this study, there were found out several features. The first, the rental fees are going higher when it closed to the first floor in commercial buildings. Therefore lower level stores have more expensive rental fees, and the stores, which are located on the first floor, are influenced by accessibility more than other businesses. Also, they are willing to pay more rental fees relatively. However, the stores, those are located on upper level in the building, have less influenced by accessibility. The second, ratio of area for exclusive use is increased by upper level than lower level in the commercial buildings. It looks like the owner would like to make more tenant on the lower floor due to high rental fee, also there are more demand on the lower level than upper level stores. Thus, the study find out that the businesses located on lower level are not to demand large space, and the upper level stores are figured out the opposite phenomenon. The third, the floor is decided by the business' features. Each business has different importances for its business such as main factor, requirement of space to run business, and solvency of rent. It looks like these elements effects on decision of floor, and it shows the difference of distribution in the commercial buildings. 2. RESULTS This result of this study, the location of commercial type of business looks like has been decided by feature of business, feature of floor, rental fee, ratio of area for exclusive use.

A proper establishment of the medical service area for a region is essential for the rational allocation of health resources. Thus, this study aims to analyze a spatial interaction of hospital utilization in Chungnam Province and to examine the impact of the location of university hospital on the medical service area. The method of cluster analysis is applied based on the Kullback's minimum discriminant information as a criterion of proximity. As a data set for this study, an inpatient home-hospital flow matrix is formulated from the inpatient records of each hospital in the study area. And from this data set an isometric image of the hierarchical structure is drawn for each of the inpatient flow matrix. The findings of the research are as follows; First, the characteristics of inpatient home-hospital transit pattern shows that the older age group and internal treatment department reacts more sensitively to spatial accessibility of the location of university-hospital than younger age groups and other departments. Second, the city of Chonan plays a major role in providing medical services in the regional medical service area, although the city is located in the northern part of the Province. Third, the impact of new location of university hospital tends to be greater in the area within 60㎞ from the facilities, and in the area without a general hospital nearby over 60㎞ from the facilities. Fourth, the impact of the location of university hospital tends to decrease with the lapse of time. Fifth, the number of medical service areas and the type of medical services provided are changing rapidly in the case of Chungnam Province. This indicates the fact that the medical service area of the Province is not established properly. Last, the result of this study requires that the current establishment of medical service area should be adjusted based on the inpatients' home-hospital transit behavior.

Korea is the most rapidly aging country in the OECD countries, becoming 'an aging society' in 2010, when over 12% of the population had reached the age 65 and beyond. Along with the population aging, problems of the elderly have become a social issue. Also, the elderly population in most farming villages is increasing due to the cityward concentration of younger generation and the rapid urbanization centered around the capital area. Yet no definite success in revitalization of these villages has been reported despite the acknowledgement of the problems arising from such phenomena. Therefore, by examining "marginal villages" (communities whose joint social activities are difficult to maintain as over 50% of the population is 65 years or older) in Japan, which at this point has entered "the ultra-aged society" before Korea, this study intends to compare and analyze the countermeasure plans for the population decrease in these villages. The case study has been done with the focus on the literary references published in Japan such as papers, various reports, statistics, newspapers, and journals.

옥외광고물 표출면적 총량제에 관한 연구

이경아(Lee Kyong A),김병량(Kim Byung Ryang) 한국옥외광고학회 2011 OOH광고학연구 Vol.8 No.4

우리나라 도시의 상업 건축물은 1980년대 이후 다양한 성격의 용도가 하나의 건물군으로 복합화하는 성향을 나타내고 있다. 복합화 성향은 다양한 지역에 나타나지만 특히, 신도시 주거지역 배후시설의 복합화는 경관적으로도 매우 주목할 만한 것이다. 옥외광고물 총수량은 해마다 급증하고 있으며 이 중 약 50%가 불법광고물로 파악되고 있다. 이들 옥외광고물의 대부분은 고밀도, 과대크기, 자극적·원색적 디자인, 건물과의 부조화, 획일화 등의 문제를 안고 있다. 상기의 문제를 해결하고자 옥외광고물에 대한 규제와 개선의 수단으로 옥외광고물 가이드라인 도입, 고시지역확대, 옥외광고업자 자격강화, 광고물실명제, 옥외광고자율관리지역 등 다양한 행정적·제도적 수단이 동원되고 있다. 2011년 상반기에는 옥외광고물등관리법 및 시행령이 개정되었으며 이에 따른 지자체의 조례개정 또한 진행될 것이다. 그러나 상기와 유사한 행정적·제도적 대응이 있었음에도 불구하고 개선되지 않고 있는 옥외광고와 관련한 작금의 상황은 간판의 영향력을 인정하고「간판악영향」을 개선하여야 한다. 이에 본 연구에서는 가로경관을 개선하기 위한 옥외광고물의 문제를 해결하기 위해 건축물 전면적에서 광고물이 차지하는 면적을 총량의 개념으로 관리하는 방안을 통해 건축물의 입면 개선에 대한 '광고면적 총량제'로 연구·탐색하였다. 광고면적 총량제는 건물의 입면 구조와 크기에 따라 부착할 광고물의 면적을 일정한 범위내로 제한함으로써 획일적으로 설치되는 광고물의 크기를 제한하여 일방적으로 노출되는 광고물로부터 가로환경의 질을 개선·보호하고자하는 제도로 정의할 수 있으며, 건축물 광고면적 총량제, 가로별 광고면적 총량제, 광고내용 면적 총량제로 세분 할 수 있다. 간판이 아름다운 거리 조성사업지 10곳을 대상으로 총량률 분석 결과를 종합하여 보면 광고물의 수량은 평균 37.3개에서 평균 16.7개로 감소하였으며, 광고표출면적 총량은 평균 41.4%에서 평균 23.5%로 감소하였다. 이는 간판 시범가로 조성사업의 시행과 옥외광고물 가이드라인의 적용에 의한 것으로 가로의 이미지에 대한 쾌적성 지수가 향상 시키는 유의미한 요소로 나타났으며 바람직한 광고면적 총량의 도출로 활용 될 수 있다.
