최근 지구온난화와 기후변화에 관련된 각종 징후들이 여러 분야에서 주요 화두로 자주등장하고 있다. 이들은 주로 평균기온의 상승이나 강우패턴의 변동 등과 같은 기상학적 특성변화를 중심으로 다루어지고 있는데 이를 수문학적 관점에서 유추해 본다면 물 순환과정(hydrological cycle)내 성분별 거동양상의 변화로 해석할 수 있을 것이다. 유역의 특성을 파악하고 발생할 수 있는 수자원의 양적 불균형에 따른 문제점을 탐지하여 그에 대비하기 위해서는 무엇보다도 신속한 정보의 제공이 우선되어야 한다. 또한 이러한 정보를 이용하여 유역의 습윤 및 건조 상황을 모니터링하거나 예측하기 위해서는 즉각적이고 연속적인 정보의 수집이 요구된다. 본 연구에서는 기 수행된 연구결과를 바탕으로 기후학적 물수지 방법에 의하여 1998년부터 2004년까지의 금강유역에 대한 습윤지표를 산정하였다. 그러나 습윤지표가 유역의 습윤 혹은 건조상태를 반영한다고 하나 습윤지표에 익숙하지 않은 사용자의 경우 직관적으로 이 지표만을 이용하여 유역의 상황을 판단하기에는 어려움이 있다. 따라서 본 연구에서는 습윤지표를 통계학적 분포특성에 따라 유역의 습윤 및 건조 상황으로 분류하는 방법을 제안하였으며, 이를 바탕으로 당시 지역적 실제 현상과의 연관성 등을 통하여 가뭄을 평가하는 방법을 제안하고 자 한다.

The purpose of this study is to develop the indicators for measuring enjoyment of public libraries by the community. The term, enjoyment is defined as the community members' use and appreciation. Four types of enjoyment indicators are constructed through literature review: basic(environment), state(use), result(outcome), and essential(to enhance enjoyment). The prepared enjoyment indicators are evaluated and selected by focus groups interviews of professionals(researchers, librarians and policy makers). Those selected indicators are tested and revised through a internet survey of 508 Kyungi residents. Based on the analysis of the results this study suggests a total of 46 enjoyment indicators.

우리나라의 대표적인 도서지역인 제주도는 일반 내륙지역과 달리 지표수-지하수에 대한 연구가 지하수계에 대한 연구에 비해 미미한 실정이다. 제주도의 경우 내륙과 달리 대부분의 하천이 평상시 건천의 형태로 유지되며, 일정한 강우가 도달해야만 지표유출이 발생하는 경우가 많다. 이와 같은 하천특성은 내륙과 매우 상이하여 일반적으로 사용되는 유역 수문해석 방법으로는 수문성분의 정확한 산정을 기대하기 어렵고 이로 인해 지하수 해석에 있어서도 불확실성이 크게 증가하는 요인이 된다. 따라서 지표수의 정확한 거동과 지하수 해석의 불확실성을 줄이기 위해 유역개념의 물순환을 해석할 수 있는 지표수-지하수 연계 해석기술이 필요한 실정이다. 본 연구에서는 '삼다수 먹는샘물 환경영향조사'가 수행되어 비교적 정확한 지하수위 관측 자료가 확보되어 있고, 매우 제한적이기는 하나 하천의 유출량 조사가 수행된 바 있는 제주 표선 유역에 완전연동형 지표수-지하수 해석 프로그램인 SWAT-MODFLOW을 이용하여 지표수 유출성분과 지하수 유동변화를 동시에 고려한 분석을 수행하였다. 특히 MODFLOW의 Well 패키지와 SWAT의 물이동 옵션을 결합하여 표선유역의 198개 관측공의 양수를 동시에 모의하였다. 모의결과 지하수위는 비교적 양수에 비해 안정되게 유지되는 것을 알 수 있었고 이를 통해 현재 삼다수 공장의 양수량은 현재로서는 과다양수가 아닌 것으로 판단되었다. 현재의 양수량의 10배를 가정하여 모의를 한 결과, 지하수위는 함양에 의해 다시 회복되는 결과를 보이고 있어 이 지역의 실제 개발가능량에 대한 보다 심도있는 논의가 필요한 것으로 판단되었다. 나아가 이와 같은 분석을 통해 제주 지역의 전체의 지하수 개발가능량을 산정할 경우 제주지역의 지하수 관리방안이 새롭게 제시될 수 있을 것으로 기대된다.

As the entrepreneurial ecosystem turns out to be a leading factor in improving nation's entrepreneurship, many studies are underway in the country to develop the start-up ecosystem. Although the entrepreneurial ecosystem is receiving attention as an essential factor for the nation's economic growth as well as entrepreneurship due to its inter-relationship with start-ups, government agencies and investors, criticism of measurement indicators has been increasing due to the different institutional and political contexts of each country, including the various definition of start-up ecosystem. In this study, we develop indicators that are suitable for domestic conditions in Korea and that can measure the level of start-up ecosystems in each regional level. FGI and Delphi surveys by scholarly experts in each field of start-ups & entrepreneurship were conducted to verify how well existing indicators fit the domestic situation and to develop indicators that can measure the local entrepreneurial ecosystem in Korea through close examination. As a result, the local entrepreneurial ecosystem consisted of three to four sub-components and 38 sub-components, each consisting of seven indicators, including Policy, Investment, Culture, Market, Human Capital, Support and Knowledge. It is expected that this research will be used to diagnose local start-up ecosystems and to propose discriminatory policies that can complement regional strengths and weaknesses.

Land Use and Land Cover Changes (LUCC) occur over a wide range of space and time scales, and involve complex natural, socio-economic, and institutional processes. Therefore, modelling and predicting LUCC demands an understanding of how various measured properties behave when considered at different scales. Understanding spatial and temporal variability of driving forces and constraints on LUCC is central to understanding the scaling issues. This paper aims to 1) assess the heterogeneity of land cover change processes over the landscape in northern Ghana, where intensification of agricultural activities has been the dominant land cover change process during the past 15 years, 2) characterise dominant land cover change mechanisms for various spatial scales, and 3) identify the optimal spatial scale for LUCC modelling in a savanna landscape. A multivariate statistical method was first applied to identify land cover change intensity (LCCI), using four time-sequenced NDVI images derived from LANDSAT scenes. Three proxy land use change predictors: distance from roads, distance from surface water bodies, and a terrain characterisation index, were regressed against the LCCI using a multi-scale hierarchical adaptive model to identify scale dependency and spatial heterogeneity of LUCC processes. High spatial associations between the LCCI and land use change predictors were mostly limited to moving windows smaller than 10$\times$10km. With increasing window size, LUCC processes within the window tend to be too diverse to establish clear trends, because changes in one part of the window are compensated elsewhere. This results in a reduced correlation between LCCI and land use change predictors at a coarser spatial extent. The spatial coverage of 5-l0km is incidentally equivalent to a village or community area in the study region. In order to reduce spatial variability of land use change processes for regional or national level LUCC modelling, we suggest that the village level is the optimal spatial investigation unit in this savanna landscape.

The paper has its focus on comparative appraisal of sustainable development in korean metropolises. In reference to OECD, UNCSD, PCSD and BBR indicator lists, somewhat transformed 14 themes and 42 quantitative indicators were chosen in economic, social and environmental sector. In next step, for the standardization of the indicators the own value of each Metropolis was relatively appraised based on the mean value of each indicator of the metropolises. If necessary, the indicator which has negative characteristics was transformed into positive scale so as to compare all of the indicators with same scale direction. As a result, it was found out that Seoul and Ulsan, highly concentrated in specific economic sector, reveals high level of sustainable development in economic sector but not in environmental sector. Kwangju is diametrically opposed to the former case. In contrast to the generally low level of sustainable development of Pusan, Taegu and Incheon, the metropolis Taejeon shows equally high level of sustainable development in 3 sectors.

Korea's self-support program has constituted one of the most important workfare policy for the past 25 years. However, many pointed out the lack of field perceptions in the performance indicators of self-support program, such as overemphasis on the economic performance and uniform application regardless of regional types. This research intends to derive policy implications to improve performance indicators of self-support program by analyzing field perceptions, utilizing ISA(Importance-Satisfaction Analysis) method. Analysis on the difference between importance and satisfaction shows that the procedure was perceived more important than the consequences. It also reveals that current indicators were not satisfactory enough to reflect field practices. Finally, ISA matrix classified indicators into keep, improve, policy reconsideration area, and obvious differences were found by regional type. These findings suggest the importance of field-orientation in performance indicators, and by which, can serve as an exploratory study for the improvement of performance indicators.

This study was carried out to define the characteristics of the identified ground-dwelling invertebrate communities at Nari basin and Tonggumi area in Ulleungdo Island, designated as a nationally important agricultural heritage. The habitat types were divided into the following categories: crop land, forest, and ecotone, and the soil-dwelling invertebrates were collected according to habitat type. The ground-dwelling invertebrates were collected using a pitfall trap, and a self-organizing map (SOM) was applied to the invertebrates dataset to define the characteristics in invertebrates distribution. The SOM clearly classified the relevant information into four clusters, and extracted ecological information from the invertebrates dataset. The cluster II was composed of invertebrate communities which are collected in the Tonggumi area. The Tonggumi area is where mountainous areas were developed for agricultural purposes, which has geographical features commonly observed in Ulleungdo Island. It is noted that the cluster II has different characteristics as compared other clusters. The results of this study are expected to be used for the preservation of agricultural environment and maintenance of biodiversity by providing basic data, on the biotope of Ulleungdo Island designated as a nationally important agricultural heritage and information on the characteristics of the applicable ground-dwelling invertebrate communities.
