With a view to creating beautiful farm villages, this study aims to exploit space syntax and thereby establish a systematic plan for refurbishing common farming facilities in farm villages by expanding a remodeling plan that has so far been focused on farm houses to cover different villages as well as in spatial scope. For this purpose, the study has extracted a system of categories for common ownership facilities in farm villages and applicable elements needed for collaboration in the space of joint production by performing a comprehensive analysis of related literature for the purpose of researching the distribution of common farming facilities. Based on such categorization of applicable elements, the study conducted a field survey of the four types of farm villages such as suburban area (Hwaseong), inland farming-centered area (Jeungpyeong), coastal & plain area (Goheung), and mid-mountain area (Gangneung), through group discussions by participating researchers and field pilot surveys. Also, space analysis has come up with measurements based on the five criteria of integration, local integration, control, connectivity, and spatial depth. And a plan for type-specific remodelling of common farming facilities has been drawn up through standardization based on the values in integration for different villages and spatial depth for common farming facilities. The significance of the current study consists in identifying how the location of common farming facilities influences the characteristics of different villages in terms of spatial structure and then drawing up guidelines for planning their placement.

This study aims to design and implement a traffic model that can simulate the traffic behavior on the microscopic level by using the GIS. In the design of the model, the vehicle in the simulation environment recognizes the GIS road centerline data as road network data reflecting number of lanes, speed limit and so on. In addition, the behavior model was designed by dividing functions into the environmental perception model, time headway distribution model, car following model, and lane changing model. The implemented model was applied to Jahamun-road of Jongno-gu district to verify the accuracy of the model. As a result, the simulation results on the Jahamun-road had no great error compared with the actual observation data. In the aspect of usability of model, it is judged that this model will be able to effectively contribute to analysis of amount of carbon emission by traffic, evaluation of traffic flow, plans for location of urban infrastructure and so on.

Researchers and scientists spend huge amount of time in analyzing the previous studies and their results. In order to timely take the advantageous position, they usually analyze various resources such as paper, patents, and Web documents on recent research issues to preoccupy newly emerging technologies. However, it is difficult to select invest-worthy research fields out of huge corpus by using the traditional information search based on keywords and bibliographic information. In this paper, we propose a method for efficient creation, storage, and utilization of semantically relevant information among technologies, products and research agents extracted from 'big data' by using text mining. In order to implement the proposed method, we designed an ontology that creates technological knowledge for semantic web environment based on the relationships extracted by text mining techniques. The ontology was utilized for InSciTe Adaptive, a R&D trends analysis and forecast service which supports the search for the relevant technological knowledge.

본 연구는 2012년 시행할 예정인 신재생에너지 공급의무화제도(RPS) 하에서 신재생에너지 전력에 대한 추가비용 발생 시 국민들이 RPS 제도의 목표 및 형태에 대하여 어떤 선호를 가지고 있으며, RPS 제도에 대한 소비자들의 만족도를 높이기 위한 개선점이 있는지 알아보고자 수행되었다. 이에 소비자 선호를 조사하는 대표적인 연구방법론인 조건부가치평가법(CVM)을 활용하여, RPS 제도 하에서 발생 가능한 소비자 선호, 구성요소 합산효과 및 지역별 선호의 차이의 3개 주제에 대한 연구를 3차례 설문을 통해 수행하였다. 해당 연구의 주요 내용을 요약하면 다음과 같다. 첫째, 우리나라 국민들의 신재생에너지 전력에 대한 WTP는 가구당 1,456~1,560원/월 수준으로 이는 우리나라 가구당 월 평균 전기요금의 약 3.7~3.5% 수준에 해당한다. 이를 토대로 추산한 신재생에너지 전력 이용에 대한 국민들의 편익은 2011년 신재생에너지 보급 관련 예산의 42.4% 정도인 것으로 나타났다. 둘째, 국민들은 에너지원의 선택에 대한 비용 차이가 있을 시에는 개별 신재생에너지원을 대체재(substitutes)로 인식하였다. 그러나 에너지원의 선택에 대한 비용 차이가 없는 경우에는 특정 신재생에너지원에 대한 선호를 보이며, 특히 태양광에 대한 선호도가 가장 높게 도출되었다. 셋째, 소비자들의 선호도에 따른 재생에너지 포트폴리오를 적용한 결과, 우리나라 국민들은 연 2,618~2,806 GWh 규모의 신재생에너지 전력을 생산하는데 소요되는 추가비용을 지불할 의사가 있는 것으로 분석되었다. 이는 2010년도 우리나라 전체 전력 수요의 0.62~0.66% 정도로 RPS에서 목표로 하는 의무비율을 이행하기에는 부족한 것으로 보인다. 넷째, 신재생에너지 전력에 대한 선호는 지역별로 다르게 나타났다. 이는 지역 간 저항응답의 비율, 재생에너지 시설 인근 경험 및 재생에너지 시설 입지에 대한 찬반의사 등의 지역별 차이에서 기인하는 것으로 분석되었다.

This study investigated the international transfer of retail know-how via the prism of Learning Organizational Theory. As a case, 7-Eleven, a worldwide chain of convenience stores was examined. Its international transfer of retail know-how occurred when 7-Eleven, originally founded by Southland Corporation in Dallas, Texas, was introduced in Japan in 1973 in the form of 7-Eleven Japan. Our analysis shows that both strategic core learning and adaptive learning played a significant role during the international transfer of retail know-how. Our findings reveal the evidence of the following elements of strategic core learning such as the convenience store concept, the three principles of store management, the minimum profit guarantee system, and the margin-based royalty system. On the other hand, the retailing mix such as store type, store location, store size, and merchandising acted as the acting agents of adaptive learning. The hypothesis verification methods acted as the main methods for adaptive learning. Through the persistent adaptive learning, inimitable innovations could be brought forth. However, the elements of strategic core learning should provide the direction for the adaptive learning.

전 세계적으로 인공습지는 도시화, 기후변화 및 생활수준 향상으로 인한 홍수와 가뭄, 하천생태계 변화, 수질오염과 같은 환경문제의 해결방안으로 제시되고 있다. 이에 따라 국내에서도 여러 목적과 형태의 인공습지가 조성되고 있다. 인공습지의 경우 특정 기능을 목적으로 하여 조성하더라도 인공적 생태계가 조성되므로 복합적 기능을 갖게 된다. 하지만 현재까지의 인공습지 조성 효과에 관한 연구는 한가지 기능에만 초점을 맞추어서 실제 인공습지 조성의 가치가 저평가되고 있다. 본 연구에서는 하천변 인공습지 조성에 따른 여러 효과 중 가장 주가 되는 홍수저감 및 수질개선 기능에 대한 효과를 분석하고 이에 따른 편익을 산정하였다. 먼저 인공습지의 적용 대상 유역을 선정하고 유역 내에 입지를 결정하여 이에 맞는 인공습지를 설계 및 적용하였다. 인공습지 조성에 따른 홍수저감 효과 및 수질개선효과를 각각 분석하였다. 분석 결과에 대해 MD-FDA를 통해 홍수피해액을 산정하였고 대체비용법을 통하여 동일한 수질개선 효과를 갖는 하수처리시설의 하수처리비 및 운영관리비에 해당하는 수질개선 편익을 산정하였다. 본 연구를 통해 인공습지의 홍수저감 효과뿐만 아니라 수질개선 효과를 확인하였으며 정량적인 분석방법을 통해 두 가지 기능에 대한 효과를 분석하여 보았다. 또한 산정된 홍수저감 및 수질개선 효과를 경제적 가치로 환산하여 보다 객관적인 지표로 나타내었다. 본 인공습지 조성에 따른 종합적 편익 산정 연구 결과는 다목적의 인공습지를 적재적소에 적용하는데 기여할 것이다. 추후 생태적 기능, 레크레이션 기능 등에 따른 기타 편익 산정 방법론 조사를 통해 각 기능의 편익을 추가한다면 인공습지 조성에 따른 편익을 종합적으로 고려할 수 있을 것으로 판단된다. 또한 인공습지 조성의 소요사업비 및 유지관리비를 산정하여 인공습지 조성에 대한 경제성분석을 한다면, 실제 인공습지 조성 사업 시 사업의 타당성을 평가하는 기초자료로 활용할 수 있을 것으로 기대된다.

The position, size and landscape of the former Donam SeoWon as well as the physical organization of the old site, are studied to extract data for the enhancement of the authenticity of Donam SeoWon since its registration as a world heritage site. The results are as follows. The 'Donam(豚巖)' encaved rock, the tombstone of teacher Sagye(沙溪), Kimjipsadang(金集祠堂), the head of the Gwangsan Kim family, the Sagye stream in front of them, and the Gyeryong and Daedun mountains in the distance are united in the former Donam SeoWon as landscape elements that clearly show the characteristics of the former site, which was called 'Donam-Wollim(豚巖園林).' Moreover Yangseongdangsipyoung(養性堂十詠), adds the garden elements of a medical herb field, twins pond, a bamboo forest, a school, and a peach field. On this site, one can also engage in activities that are related to the land and are closely related to Neo-Confucianism such as fish watching, conferencing, visit in seclusion(訪隱), looking for monks, and overseeing farming. The former site facing east is assumed to have Sau(祠宇) - Eungdodang(凝道堂) - Ipdeokmum(入德門) - Sanangru(山仰樓: estimated). Jeonsacheong seems to have been located to the left of the Sau area, Yangseongdang, which contained upper and lower twin lotus ponds, on the right and was surrounded by various plants. As it has been used as a lecture hall for the past 250 years, the former Donam SeoWon, located 1.8km away from the current area, must be preserved, and the landscape should be formed to establish the authenticity of Donam SeoWon.
