This study verified the limitations of commercial GPS data processing software and the applicability on precise positioning through comparing the processing results between Bernese and TGO under various conditions. To achieve the goal, we selected three nationwide station data and two smaller local data to constitute networks. By using Bernese and TGO, those networks are processed through the baseline analysis and the network adjustment. The comparative analysis was carried out, in terms of software, baseline length and network scale, observation duration, and number of fixed points. In the comparison between softwares, the scientific software was excellent in accuracy. It was confirmed that, as GPS-related technology is developed, the performance of the receiver was enhanced. And, in parallel with this, even the functionalities of the commercial software were tremendously enhanced. The difference, however, in result between the scientific and commercial software are still exist even if it is not big. Therefore, this study confirms that the scientific software should be used when the most precise position is necessary to be computed, especially if baseline vectors are big.

In order to investigate any differences of the characteristics of goat milk according to seasons and individual farms, we analysed and compared the components of fat, protein lactose, total solid, solid-not fat (SNF) and cells of goat milk collected from 8 individual farms between December 2006 and June 2007. Milk fat content has shown higher values in December to March than in other seasons, and SNF appeared especially higher in February. However, lactose content was not different according to seasons. Regional differences of milk components were not big at all either. Milk components from goats were in general similar to cow milk except a little lower fat content, but appeared higher than mare milk. Production of goat milk is in difficulty in aspects of balancing demand and supply due to its seasonal reproductive system. For the future of goat milk industry, it is necessary to develop various products of longer storage life.

The purpose of this study is to analyze characteristics of welfare level for the persons with disabilities in Korean local governments. The study adopted multidimensional scaling and cluster analysis. Based on prior studies and comparative importance research, three indicators were extracted from the welfare circumstance index for the disabled. They are the ratio of the registered disabled population, the ratio of the disabled household in poor households, the ratio of dependence on public finance. Also, nine dimensions and twenty seven indicators were extracted from the welfare level index. The dimensions are as follows : Education, income & economic activities support, welfare services infra-structure, health & welfare service support, movement convenience & safety, rights protection, culture, leisure & information accessibility, welfare administration & budget for the disabled. The findings from the welfare circumstance index show that local governments are divided into three groups and all indicators are statistically significant. On the other hand, the findings from the welfare level index, show that local governments are divided into four groups and five indicators are statistically significant. Based on these findings, the study proposes improvement in the disabled welfare level, and balanced development of local governments.

농업 분야에서 미생물은 영양분 가용화, 유기물 분해 등 토양 영양분 공급에 중요한 역할을 하며, 토양 건강성 증진, 식량 안보 및 식품 건강 면에서 많은 활용 가능성을 지니고 있다. 최근 유역 환경 건강성, 생물 다양성 보존, 효율적인 고품질 농산물 생산에 대한 관심이 커져, 지속 가능한 농업 중 하나인 유기농업과 관행농업 토양의 이화학적 및 생물학적 특성에 관한 비교 연구가 진행되고 있다. 미생물은 지속 가능한 농업 발전의 중요한 요소 중 하나로써, 미생물 다양성이 풍부할수록 토양 비옥도, 작물 성장 면에서 긍정적인 영향을 미친다고 알려져 있다. 본 연구는 이에 대한 기초 데이터를 제공하기 위해 논 경작지를 대상으로 유기 및 관행농업 토양의 미생물 군집조성과 Alpha diversity analysis(Chao1, Shannon, Simpson index)을 통해 비교하였다. 경기도 양평군에서 유기 및 관행 논 지역을 각각 1지점씩 선정하였으며, 8월부터 11월까지 총 4회 현장 조사를 진행하였다. 미생물 분석은 차세대염기서열분석을 실시하였으며, bacteria는 16S rRNA V3-4 영역, fungi는 ITS 3-4 영역을 sequencing 하였다. 미생물 군집조성은 문수준에서는 큰 차이가 없었으나, 속수준에서는 fungi 군집조성에 차이를 보였다. 예로 Ustilaginoidea 속은 관행 논 토양에서만 발견되었으며, 벼 이삭누룩병을 일으키는 병원균으로 과도한 질소 비료 시비가 원인으로 추정된다. 종 다양성은 bacteria diversity의 경우 관행 논 토양에서 높게 측정되는 반면, fungi diversity의 경우 유기 논 토양에서 높게 측정되었다. 결론적으로 체계적인 시비 관리 통해 미생물 군집은 조절될 수 있으며, 관행농업은 적절한 시비를 통해 토양 건강성 및 식품 건강성 면에서 유기농업과 비슷한 효과를 보여줄 가능성이 있다고 판단된다.

Recently, the changes of industrial location can be explained as the concentration of small and medium manufacturing firms or high technology industries by industrial restructuring in Seoul metropolitan area, and the dispersion of large companies'branch plant into the peripheral region in Korea. Particularly deindustrialization is progressing in the inner city and manufacturing firms disperse into the outer city in Seoul metropolitan area. This study reviews on the structural perspectives for the changing industrial location factors. The development of capitalism organizes economic spacial structures and Its characteristics can be reasons which can raise changes in industrial location. Korean economy rapidly grew in the movement process of international capital. And capital accumulation by continuous economic growth is raising the spatial division of labor or the spatial difference and inequality on land price, wages. the base of labor reproduction. Therefore, these factors are the most reasons to raise the changes of industrial location in Korea. Hereafter the study on these factors, that is, in relation to sociocultural structure and land use structure have to be progress more concretely.

Newtown Business of Seoul had been performed to reduce deterioration of Gangbuk and economic inequality between Gangnam and Gangbuk. According to this, Eunpyeong-gu was set as test-bed for Newtown business and Newtown business had been completed until 2013. This study aims to analyze the influence of social and economical factors which affect land price using GWR (Geographically Weighted Regression) considered spatial effect. As a result of analysis, GWR model demonstrated a better goodness-of-fit than OLS (Ordinary least square) model typically used in most study. Furthermore, AIC value and Moran's I of residual prove that GWR model is more suitable than OLS model. GWR model enable to explain more detailed than global regression model as coefficient and sign show different value locally. In future, this research will be helpful to develop Eunpyeong-gu considering spatial characters and strength effectiveness of development.

As the concentration of people in urban area become severe and abnormal meteorological disasters such as regional torrential rains, heavy snows, sweltering heat, and so on have been increasing, the interest on the urban meteorological information service, which considers the specific characteristics of metropolitan areas in weather forecasting, are also increasing. The urban meteorological information service is one of up-to-date technologies which observes urban weather in a more microscale perspective compared to the present weather forecasting system and provides useful meteorological information which is specialized for metropolises in real time. Therefore, urban meteorological information service is expected to contribute to the increase in quality of life for citizens and to the development of industry in urban areas. In this study, we estimate the economic benefit of the urban meteorological information service using contingent valuation method with survey data of the citizens who are expected to be the direct customers of this new information service. As a result, we conclude that the household is willing to pay 5,963 Korean won per year on average, during a period of five years, for receiving this meteorological information service, and this willingness-to-pay is varied by the socio-economic characteristics of head of the household.

As world trade becomes more active and expansive, job mobility has progressed correspondingly in growth. In particular, high-skilled scientists (including advanced-degree holders) now possess the option of various occupational and residential mobilities. We explain the "brain drain" by using two empirical examples. One concerns the U.S. experience of foreign-born Ph.D holders living and working in the United States. The other pertains to the Korean experience, where Korean-origin and foreign-born experienced scientists are actively recruited by the government. We also explore the necessary conditions for recruiting and keeping advanced-skilled scientists, the attainment of which will result in strong future economic growth.

Ahead of the 21st Korean National Assembly Election, the congressional election law was revised, and the semi-mixed member proportional system was introduced. The purpose of the revision of the election law was to increase the proportionality and representativeness of the election system through the institutional reform in the direction of promoting a multi-party system. This study shows that the effect of the introduction of the semi-mixed proportional system was compared with the election results when the previous proportional representative system was maintained. There was no significant difference from the results. This study reveals that contrary to the intention of institutional design to revitalize the multi-party system, the two large political parties took the most seats after democratization in 1987, resulting in an unintended consequences. In addition, with regard to the recent argument for party realignment, the Busan, Ulsan, and Gyeongnam regions have been dealigned in the Yeongnam regional cleavage, and are undergoing a process of party realignment. It has not yet entered the stage of realignment, but remains in the stage of fluid dealignment.
