  • 바이오매스 자원은 고체, 액체, 기체 등의 다양한 형태의 에너지 자원으로 전환되어 이용될 수 있기 때문에 필수적인 재생에너지 자원으로 여겨지고 있다. 더불어 바이오매스는 화석 연료의 고갈과 지구 온난화를 해결할 수 있는 방법으로도 각광을 받고 있다. 바이오매스 에너지 전환 플랜트의 규모를 결정하고 경제성을 분석하기 위해서는 지역 내의 바이오매스 에너지 잠재량과 에너지 밀도에 대한 정보가 유용하게 이용될 수 있다. 농업 폐기물, 임업 폐기물, 축산 폐기물, 도시생활 폐기물 등의 국내 에너지 잠재량과 에너지 밀도를 정부 및 연구 기관들이 발표한 최신 자료를 수집하여 분석되었다. 바이오매스 자원을 확보하기 위한 지역이 증가할수록 에너지 잠재량은 증가하나 에너지 밀도는 감소하는 것으로 나타났다.

  • The main purpose of this study is to explore the factors that affect the transformation of over-depopulated rural villages. Specifically, we investigated the reasons of the rapid decrease in the number of over-populated rural villages shown by recent census data in spite of the continuing decrease of population in rural area. We used a binary-logit model and the Census of Agriculture, Forestry and Fisheries data(2010, 2015). The main results are summarized as followed: First, the over-depopulated rural villages with strong agronomic base are more likely to exit from over-depopulation. Second, returners from urban to rural have a positive impacts on the revival of over-depopulated rural areas. Thirds, improving the basic services accessibility of rural residents is also critical for keeping rural community more sustainable. These findings can be used to make effective strategies to revive the depopulated rural villages.

  • The residential population of Jeju Island has increased more than 10% for last 10 years. Especially, the tourist population is more than twice comparing to 2005. The population growth of Jeju has brought about large-scale urban development and increased land demands for tourism services. The goal of this study is to analyze the human, social, and environmental status of Jeju Island and to evaluate the environmental capacity of land use using ecological footprint (EF) model. This study shows the changes in ecological deficits of Jeju Island through estimating ecological productive land (EPL) considering EF from 2005 to 2015. The categories of total EF consists of food land, built-up land, forestry, and energy consumption. In order to reflect the characteristics of resort island, we consider not only residential population but also tourist population who can increase land demands. The outputs of this study also provide the potential excess demands of EPL and suggest needs of sustainable management plans for the limited land of Jeju Island.

  • Recently, the improvement of on-board satellite sensors covering hyperspectral image sensors, high spatial resolution sensors provide data on earth in diverse aspect. The application field relating remotely sensed data also varies depending on what type of job one wants. The various resolution of sensors from low to extremely high is also available on the market with a user defined specific location. The expense to purchase remote sensed data is going down compare to the cost it need past few years ago in terms of research or private use. Now, the satellite remote sensed data is used on the field of forecasting, forestry, agriculture, urban reconstruction, geology, or other research field in order to extract meaningful information by applying special techniques of image processing. There are many image processing packages available worldwide and one common aspect is that they are expensive. There need to be a advanced satellite data processing package for people who can not afford commercial packages to apply special remote sensing techniques on their data and produce valued-added product. The study was carried out with the purpose of developing a special satellite data processing package which covers almost every satellite produced data with normal image processing functions and also special functions needed on specific research field with friendly graphical user interface (GUI). And for the people with any background of remote sensing with windows platform.

  • Regional closed schools of about more 3,348(2010 year) have occurred all over the country according to governmental policy of 1982. Moreover, The applications of be closed school are not efficient and few studies about using community center. Also, Farmer which is the leader of revitalization of rural village could not have advantages about community center in rural area than in urban area. Therefore, The propose of study is increasing values of culture and local by using community center with closed schools. For moving ahead with study, I analysis about causes of origination of closed schools with literature and refer to the reference of the current of situation in Gyeongbuk Local Education Authority and National Statistical Office and Comprehensive Rural Community Development Program of Minister for Food, Agriculture, Forestry and Fisheries of Korea for examination of conjugating closed school through community center. According to the research, community center was to be included hall, visiting center, exhibiting space, conference room, experience room, multipurpose room, dining room, welfare space and specialized room with revitalization of rural village. I proposed improvement of law and administration and suggest several cases which already in utilization.

  • New rural village development programs have been implemented, and rural village land use is expanded to encompass green-tourism, citizen and silver domicile space because of the internal and the external changes in the agricultural environment. This study was conducted to propose the evaluation index for retiree rural village development project issued by Ministry for Food, Agriculture, Forestry and Fisheries. The evaluation index was consisted of four categories (population, economic, environment, and living), which were consisted of 35 variables. The relative weight for 35 variables was calculated based on the questionnaire survey from the experts and AHP (Analytical Hierarchy Process). Growth rate of population in population criteria, job creation by exterior inflow in economics criteria, improvement of exchange between urban and rural in life criteria, and the flood outbreak in environment criteria were the most important contents of 35 variables. These results are consistent with the objectives of retiree rural village development project, and indicate the need of prevention the negative sides by implementation of the project.

  • The scientific objectives of PACRIM (Pacific Rim) are to advance the understanding of polarimetric and interferometric radar and to promote its application in environmental research designed to detect and quantify changes found in both the physical and humanly dominated ecosystems on the earth's surface. The information derived is used to more readily identify environments at risk; improve environmental decision making and the management of resources and thereby lead to the implementation of more effective and sustainable land use practices. PACRIM is a collaborative research project was organized by NASA's Mission to Planet Earth, Airborne Sciences Program; the Jet Propulsion Laboratory; CSIRO-COSSA and the Centre for Remote Sensing and GIS at the University of New South Wales. A decade of working with AIRSAR data (1993-2003) in the Australia-Asian-Pacific region has provided the opportunity for more than 400 investigators from 20 countries to collect, analyse, interpret and apply state-of-the-art radar data to earth-science studies. This has been achieved by scientists working within seven broad research themes; o Forestry and vegetation o Geology and tectonic processes o Interferometry o Disaster management o Coastal analysis o Agriculture o Urban and regional development. This paper presents an overview of the three data acquisition missions (1993,1996 and 2000) and the science research outcomes achieved from analyzing high quality radar data.

  • Recently, growing emphasis has been placed on the installation of rain gardens. However, previous rain garden studies have mainly focused on physicochemical effects such as rainfall runoff management and water quality improvement. Therefore, this study aims to investigate general perceptions of rain gardens and landscape aesthetics among rain garden visitors. To achieve this goal, a survey of 100 rain garden visitors was conducted, gathering information about their general perceptions of rain gardens and landscape aesthetics at three pre-selected rain garden locations. Results showed that rain garden recognition was limited to 34% of the respondents, indicating that most people were not aware of rain gardens and were unable to notice differences between rain gardens and traditional gardens. However, stronger support for rain gardens was observed among those who were aware of the concept, those who recognized that rain garden planting types are differentiated from traditional gardens, and those who rated positively the landscape aesthetic value of rain gardens. The main findings are expected to encourage further studies of quantitative indicators by conducting a correlation analysis between aesthetics and functionality of rain gardens.

  • 우리나라의 토석류에 관한 연구들을 살펴보면 강우강도 및 강우지속시간, 선행강우 등의 토석류를 유발하는 강우의 특성과 토석류 발생 등에 대한 다양한 연구가 수행되고 있으며, 현재 산사태 및 토석류 예보는 산림청에서 제시한 산사태 경보 및 주의보 기준(Korea forest service, 2012)을 사용하고 있다. 그러나 산림청의 예보기준만으로 볼 때, 대부분의 피해는 주의보 기준 이상의 강우에서 발생한 것으로 나타났고, 또한 최대시강우량의 경우 주의보 이하의 강우에서도 많은 피해가 발생하였다(Hwang et al., 2013). 따라서 본 연구에서는 산림청에서 제시한 산사태 경보기준 보다 더욱 세밀한 예 경보 기준을 산정하기 위해 토석류 발생원인 인자인 강우량, 강우강도 및 누적강우량을 이용하여 강우경보지수(rainfall triggering index, 이하 RTI)를 산정하였으며, 이를 등급화 하여 관심, 주의, 경계, 대피로 구분하여 토석류 피해가 발생했던 서울시 우면산, 청주시, 인제군 피해사례를 적용하여 평가하였다. 또한 기존에 산림청에서 제시한 산사태 경보 및 주의보 기준과 비교하여 적용성을 검토하였다.
