본 연구의 목적은 공공시설물이지만 기피시설물이기 때문에 상당한 갈등을 일으키고 있는 쓰레기 소각장 입지를 선정하는데 있어서 GIS를 기반으로 다기준평가기법을 활용하여 보다 객관적이고 과학적이면서도 유연적인 후보입지를 추출하려는 것이다. 본 연구에서는 다양한 입지요인들을 표준화한 후 각 요인들이 갖는 상대적 중요도를 반영하는 가중치를 산출하고 의사결정 규칙을 적용하여 적합도 수준에 따른 후보입자들을 추출하였다. 또한 민감도 분석을 통하여 각 평가기준들에 대해 상이한 가중치를 부여하고 의사결정 규칙방법을 달리 적용하였을 경우 후보입지들의 적합도 순위에 어떠한 영향을 미치는가를 파악하였다. 이러한 방법을 통해 분석된 결과는 의사결정자들이 입지를 결정하는데 필요한 정보를 활용될 수 있으며, 따라서 GIS를 기반으로 하는 다기준 평가기법은 공간적 의사결정 지원시스템으로서으 GIS기능을 증대시킨다고 볼 수 있다.

본 연구는 산림 내 시설물의 산림환경 특성 분석을 위하여 2013년 3월 9일부터 10일 이틀 동안 280ha의 산림 피해면적과 57동의 시설물 피해를 준 울주산불에 대하여 현장조사를 실시하였다. 조사 대상물은 주택 15개소, 비닐하우스 1개소, 축사3개소 등 총 19개소에 대하여 2013년 3월부터 5월까지 현지조사를 실시하였다. 조사항목은 시설물의 입지여건, 임상분포, 주변 산불인자, 시설물 외벽구조제, 산불 등 화재진화를 위한 소방시설 여부, 기타 산불 등 화재방지를 위한 시설, 보호시설과 산림과의 거리 등 총 7개 항목을 작성하여 피해시설물 및 미피해시설물의 특성을 분석한 결과 입지여건의 경우 피해시설물과 미피해시설물은 1~2개의 진 출입로를 갖고 있었고, 도로 폭은 7m 내외로 비슷한 여건이었다. 주변 임상은 침엽수, 임분 밀도는 중, 밀임분이었다. 비가연성 외벽구조제는 피해시설물 보다 미피해시설물에 많았고, 피해시설물과 미피해시설물의 시설물 주변 가연물질 관리상태는 모두 양호하였다. 반면, 급수시설 및 스프링클러, 방화선, 방화벽 등 소방시설 및 화재방지 시설은 미피해시설물이 피해시설물보다 더 많이 구축되어 있었고, 산림과의 이격거리는 피해시설물 평균 20m, 미피해시설물 평균 25m로 조사되었다.

The purpose of this study is to show how could GIS along with digital maps and census data be used for scientific urban analysis and location analysis for a proposed project. Results are summarized as follows. First. after digital maps being completed, the census tract system being adopted, and major urban data being inputted in the computer file, GIS could be used intensively for various reliable urban analysis. With graphic statistical, and overlay functions of GIS, various physical and socio-economic characteristics of urban areas could be presented for analysis in the form of thematic and datapoint maps on the computer screen. Second, the locational analysis for a proposed project is a major part in the building permit review process, which tends to become disputable and time consuming as society become pluralized. Along with various GIS functions scientific decision-making methods could be developed, and the methods could play an important role for faster and scientific location analysis. As such, GIS would play an important role for faster and reliable urban analysis and location analysis and these functions finally would play important roles to improve public services and administration of local governments.

세계적인 기상이변으로 가뭄발생 빈도 및 영향이 증가하고 있으며, 급속한 산업화로 사용 가능한 수자원이 점차 고갈되어 있어, 국내에서도 해수담수화(Seawater Desalination)는 새로운 대체수자원으로 많은 관심을 받고 있다. 해수담수에 필요한 에너지 약 50~70%는 역삼투(Reverse Osmosis) 공정에서 발생되며, 해수온도 및 염분도에 따라 많이 변동될 수 있으므로 국립해양조사원(KHOA)의 과거 20년 자료를 이용하여 해수담수화 시설물 위치에 따른 영향을 분석하였다. 해수담수화에 필요한 에너지는 막 제조사에서 제공하는 RO Projection Software를 적용하여 에너지 소모량을 평가하고, 이를 고려한 시설물 위치에 대한 평가 모델을 구축하였다. 기존 해수담수화 시설은 대규모 물 공급이 필요한 지역을 우선적으로 고려했기 때문에 시설물 위치에 대한 객관적인 평가기준 마련이 어려웠다. 그러나 해수담수화 플랜트는 한번 설치되면 장기적인 시설물 유지 및 관리가 필요함으로 경제성을 고려한 최적 입지의 선정은 매우 중요하다. 본 연구는 국립해양조사원의 수집된 자료를 바탕으로 해수담수화 시설물 입지선정을 정량적으로 평가함으로서, 시설물 위치에 대한 의사결정시 참고할 수 있는 기초자료로 활용될 것으로 기대한다.

This study conducts quantitative analysis with the use of GIS of characteristics of Buddhism relics spatial locations such as Buddhist temple sites. With the intention of analysis of the generally known Buddhist temple site locations from spatial side, following the Buddhism relics sites state, the present conditions of Buddhist temple sites was analyzed from the spatial point of view. The results of the present study are that, comparing with general location analysis, different characteristics of competitive strength which maintains Buddhist temple sites functioning until now are showing. In case of such cities as Chuncheon and Wonju, Buddhist temples exist in the areas of high locational competitiveness, and most of them were located in the areas which with relatively poor environment. On the other hand, comparing with Samchuk city case, the location environment of Buddhist temples there turned out to be excellent. Such results show that we can discover the special characteristics of Buddhism which holds the entire history for the space called the Korean Peninsula.

This paper addresses the efficient facility placements to adopt a super WiFi network, taking significant considerations as the next generation 'information highway'. Since the super WiFi has a wider geographic coverage by utilizing the white spaces of TV broadcasting which are empty and available frequencies for the wireless communications, it would play an important role in releasing digital divide of the internet access for low populated or mountainous areas. The purpose of this paper is to explore systematic and efficient spatial plans for the super WiFi. For doing this, we applied optimal location covering models to Gurye-gun, Jeonlanamdo. From the application, we presented optimal locations for super WiFi facilities and significant analytical results, such as the tradeoff between the number of facilities and coverage and marginal coverage for establishing super WiFi network. The results of this research would be usefully utilized for decision makers who wish to adopt a super WiFi, to extend wireless networks in a city or build a regional infrastructure of wireless facilities.

The initial market of alternative-fuel vehicle (AFV) will show geographically uneven distribution due to AFV's high price, and thus efficient location model should consider spatial variation of demand. This paper estimates AFV trips by incorporating an AFV demand estimation model with origin-destination (OD) trips. The estimates are the input for the flow-refueling location model that maximizes the OD flows that can be refueled by the given number of stations considering AFV's limited range per refueling. A scenario analysis is conducted by varying assumptions in estimating demands and AFV acceptance rate. Optimal location alternatives for Orland metropolitan area are provided and results are compared.

The purpose of this study is to propose the method to improve management aspect and facilities plan to enhance spatial cognition of visitors through visitors' analysis of spatial cognition regarding tourism destination facilities. The research model was established by factors affecting spatial cognition such as facilities characteristics and visitor characteristics as well as spatial cognition of visitors' facilities to achieve objectives of research, and actual proof analysis was made to visitors to Nami Island tourism destination based of this. As a result of analysis, it was proved that visitor characteristics including their gender and age, and tour map use as well as facilities characteristics of facilities type, location, etc showed a statistically significant difference in visitors' spatial cognition. In addition, it is deemed as a result of analysis that Nami Island requires re-organization of symbolic features and attractiveness of food and beverage facility, while needing additional installment and rearrangement of information facilities and related facilities. The result of this research suggests that close analysis and application of factors affect spatial cognition such as facilities and visitors' characteristics to plan and manage the tourism destination facilities effectively. Moreover, visitors' spatial cognition is related to spatial characteristics of tourism destination, therefore it is analyzed that the uniqueness of facilities played an important role in improving female's spatial cognition. In particular, the result of this study is meaningful in that in light of plan and management for tourism destination facilities, the function to provide tourism destination plays a major role in improving visitors' spatial cognition regardless of complexity of spatial structure of tourism destination.

Small hydropower is the one of the cleanest one among new and renewable energy with less green house gas emissions. Recently, the necessity of developing small hydropower is emerging since its remaining potential resources in this country are abundant. However, a survey or research on the small hydropower development has been hardly performed since the 1990#s. These circumstances encourages a systematic approach for the small hydropower development. The purpose of this study is to propose a methodology of the location analysis for developing small hydropower. To this end, constraint and location criteria with weights are established and quantification method of each factor is presented. Especially, the analysis procedure is established on the basis of GSIS. Also the study focus on raising the objectivity and precision of analysis by developing system model with automatic search. The proposed methodology is applied to Bochung stream in Keum Riverbasin. The result selects the four and two locations of dam type and run-of-river type respectively. This study will be beneficial to the future activation of small hydropower development as a fundamental work.
