기존의 공간구문론(Space Syntax)을 활용한 공간구조분석(Spatial Structure Analysis)은 가로망(road)에 관한 인자(factor)만을 활용하는 한계를 가지고 있기에, 가로망 인자만이 아닌 지역의 지역적 특성을 고려한 인자를 도출한 현실성 있는 공간구조 분석 방법이 필요한 실정이다. 본 연구는 지역의 공간구조 특성인자를 도출하여 기존의 공간구문론과 GIS와의 통합모델을 구축하여 수정형 공간구조분석 방법을 제시하고 합덕읍 일원의 중심지역을 대상으로 공간구조 분석을 수행하는데 목적이 있다. 이를 위해 전문가 설문조사를 실시하여 지역의 공간구조 특성요인 및 상대적 가중치를 도출하였고, 지역적 특성을 반영하는 인자로 가로망 뿐만 아니라 용도지역, 지가, 건물의 밀집도 요인을 도출하였다. 분석 결과 합덕읍의 경우 도로만을 이용한 기존의 공간구조분석을 활용한 공간구조분석 방법이 실제적인 값을 반영하지 못한 것으로 분석되었고, 지역적 특성 인자를 추가하여 분석한 수정형 공간구조분석 결과가 합덕읍의 현실성을 잘 반영한 것으로 나타났다. 즉, 합덕읍과 같은 경우 개발 축에 따라 가로망이 변화되고 중심성이 변화되는 지역이 아니라, 효율성과 형평성에 의해 가로망이 형성되거나 쇠퇴로 인해 중심성이 변화된 지역이기에 이러한 지역의 경우 지역적 특성을 반영한 방법이 더 적합한 것으로 분석되었다. 향후 지역적 특성을 반영한 공간구조분석 인자 선정 및 파라미터 선정에 관한 더 깊은 연구가 필요하고 다른 지역을 대상으로 시뮬레이션하여, 모델에 대한 상호 검증 및 보완하는 과정이 필요할 것이다.

The purpose of the study was to find out the relationship between subjective happiness and satisfaction of social sustainability in residential environment. The data for the analysis were collected through questionnaire survey method from October 29 to November 10, 2013, and the sample consisted of 338 residents living in Seoul and Gyeonggi-Do province. The social sustianability was composed of locality, communality and organism. Locality composed of historical and cultural reflection of regional identity and of regions. Communality composed of social integration, community program and facilities. Organism composed of employment, self-sufficiency, welfare, population, safety and housing. The findings of the study were as followings: 1) The average of subjective happiness was 3.82 points, over neutral. 2) The social sustainability in residential environment was related with the subjective happiness. 3) In the social sustainability in residential environment, the residents was satisfied with locality and organism, but they was not satisfied with communality.

The purpose of this study is to investigate the architectural change of the modern Korean farm-houses. Regional boundary of this study is confined to Pocheon-Gun, and the object is mainly forty-two farm-houses as long as sixty years since it was built. An analysis is made on the change of spaces, facilities and finished materials of farm-houses. The results of this study, An-Chae have changed for the more comfortable living conditions through the spatial changes as like the fittest facilities with spatial extension and integration. And in Arae-Chae, unlike An-Chae, the old and unused space often have transformed to the other function and the its facilities remained still unimproved.

So far, the water management have separately been accomplished by water supply, flood control, and environmental river management. In spite of sustainable policy of water resource development, flood & drought damage, poor water accident, and deterioration of river ecosystem have continuously occurred. It means that it is difficult to improve those problems with the present systems and institutions. So, it is time to discuss to change the present water management system of administrative sense into the one classified by the watershed in order to understand problems of water resource in the regional basis. First, a integration of similar branch office in organization and a work specialization should be driven in the government. Second, it is desirable to develop the water resources according to the inherent characteristics of the watershed.

In meteorology, exploitation of Kalman filter as a data assimilation system is virtually impossible due to simultaneous requirements of adjoint model and large computer resource. The other substitute of utilizing ensemble Kalman filter is only affordable by compensating an enormous usage of computing resource. Furthermore, the latter employs ensemble integration sets for evolving the background error covariance matrix by compensating the dynamical feature of the temporal evolution of weather conditions. We propose a new implementation method that works without the adjoint model by utilizing the explicit expression of the background error covariance matrix in backward evolution. It will also break a barrier in the evolution of the covariance matrix. The method may be applied with a slight modification to the real time assimilation or the retrospective analysis.

Water resources management depends on dealing inherent uncertainties stemming from climatic and hydrological inputs and models. Dealing with these uncertainties remains a challenge. Streamflow forecasts basically contain uncertainties arising from model structure and initial conditions. Recent enhancements in climate forecasting skill and hydrological modeling provide an breakthrough for delivering improved streamflow forecasts. However, little consideration has been given to methodologies that include coupling both multiple climate and multiple hydrological models, increasing the pool of streamflow forecast ensemble members and accounting for cumulative sources of uncertainty. The approach here proposes integration and coupling of global climate models (GCM), multiple regional climate models, and numerous hydrological models to improve streamflow forecasting and characterize system uncertainty through generation of ensemble forecasts.

This article examines the nature of geopolitics and its impact on the international political economy of Eurasia/Silk Road. The research questions are exploratory and aim at revealing the differing geopolitical perceptions of the Russian Federation, the People's Republic of China (PRC) and the former Soviet Central Asian countries-Uzbekistan, Turkmenistan, Tajikistan Kyrgyzstan and Kazakhstan-within the context of an emerging "New Silk Road". Consequently, the main goal of this article is to contribute to a better understanding of what factors constrain and shape Silk Road initiatives in Eurasia. To this end, the article focuses on geopolitics and regional integration theories through a consideration of the Silk Road initiatives of a number of Eurasian countries.

A three-dimensional linear model and the Advanced Regional Prediction System (ARPS) were used to simulate parabola-shaped disturbances and clouds in the lee of a bell-shaped mountain. The ARPS model was compared in the x-y plane against the linear model's analytic solution. Under similar conditions with the linear theory, the ARPS produced well-developed parabola-shaped mountain disturbances and confirmed the features are accounted for in the linear regime. A parabola-shaped cloud in the lee of an isolated bell-shaped mountain was successfully simulated in the ARPS after 6 hours of integration time with the prescribed initial and boundary conditions, as well as a microphysical scheme.

Some devices of sustaining the small scale farming in the changing social and economic conditions in which comparative disadvantages are evidently to be experienced in the near future, are becoming a central proposition in the Korean agriculture. In this connection, development of integrated activities in farming among individual farmers within a region may be an important device of overcoming prevailing limits of resource possession and use of individual farmers. These inter-farm or inter-group cooperation and integration can be promoted through establishing efficient cooperative system within a farming district. This study was undertaken to find facts pertaining to situations leading to successful performence of cooperative systems in group farming. In this study, The case in Cheunee Myun, Yungi-Gun, Chungchungnam-Do in which farming is specialized in production of so called "organic farming products" and farmers are integrated for increasing their productivity.ductivity.

To have the competitiveness in the future worldwide small aircraft market, we should be able to develop the aircraft which is highly safe, easy to fly, and having excellent flight characteristics. FBW(Fly-By Wire) system is essential for the enhancement of flight safety and control easiness. FBW system that has been applied only to the modern fighter and transport aircraft is recently applied to smaller aircraft such as regional aircraft, business aircraft and even small aircraft. The purpose of this research includes the development of flight control computer, the definition of FBW system component, the design concept of each component for redundant management, OFP(Operational Flight Program) development, FBW system integration and HILS(Hardware In-the Loop Simulation) verification environment to test this FBW system.
