The objective of this study is to develop evaluation indices which can be applied to analyze rational rehabilitation-policy directions of redundant farmlands. To achieve this objective, the main tasks of this research are 1) categorizing the redundant farmlands rehabilitation types 2) developing the evaluation indices of redundant farmlands rehabilitation 3) determining the weights of each index. The redundant farmlands rehabilitation types were classified into agricultural rehabilitation type, non-agricultural rehabilitation type and hybrid type which are called by agricultural income model, rural environment improvement model and hybrid model as development project name, respectively. The 5 parts and 21 indices for evaluation of redundant farmlands rehabilitation directions were extracted by case studies and experts brainstorming. The weights of each index were determined by Analytic Hierarchy Process (AHP). The developed evaluation indices were applied to study areas located on Yanghwa district of Gongju-city and Aewol district of Jeju-city. From the results of this study, it was ascertained that the evaluation indices developed in this study would help the decision-makers in the planning process of redundant farmlands rehabilitation directions.

Most of livestock houses are concentrated in certain area with mass rearing system resulting in rapid spread of infectious diseases such as HPAI (highly pathogenic avian influenza). The livestock-related vehicles which frequently travel between farms could be a major factor for disease spread by means of transmission of airborne aerosol including pathogens. This study was focused on the quantitative measurement of aerosol concentration by field experiment while vehicles were passing through the road. The TSP (total suspended particle) and PM10 (particle matter) were measured using air sampler with teflon filter installed downward the road with consideration of weather forecast and the direction of road. And aerosol spectrometer and video recorders were also used to measure the real-time distribution of aerosol concentration by its size. The results showed that PM2.5 was not considerable for transmission of airborne aerosol from the livestock-related vehicle. The mass generated from the road during the vehicle movement was measured and calculated to 241.4 μg/㎥ by means of the difference between TSP and PM2.5. The dispersion distance was predicted by 79.6 m from the trend curve.

우리나라의 재해연보를 통해 산사태의 발생 및 피해 형태를 분석하면 대부분 돌발홍수에 의해 사면 내에 유로가 발생하고 이 유로를 따라 토석류가 무너져 내리는 형태로 진행됨을 알 수 있다. 일반적으로 우리나라에 설치된 산사태·토석류 감지 및 돌발홍수 감지장비는 초기투자비 및 유지관리에 막대한 비용이 소요되며, 특히 우리나라 농촌 및 산악지역을 감안할 경우 넓은 지역에 대해 조밀한 계측 센서의 설치가 필요하므로 현재까지의 개발되어 적용하고 있는 계측센서 및 모니터링 체계를 적용하기가 곤란하다. 최근 정보통신기술이 발전하고 스마트-센서 관련 시장이 확대되면서 가속도센서, 자이로센서, 압력센서, 온도센서 등이 소형화되고 가격이 저렴해짐에 따라 기존 고가의 경사계, 간극수압계, 토양수분계를 대체할 수 있는 기술이 개발되고 있다. 또한 USN(Ubiquitors Sensor Network)과 같은 무선통신기술의 개발로 농촌지역과 같은 광범위한 감시체계를 구축해야 하는 지역에서 이용할 수 있는 센서-네크워크 기술이 개발되고 있다. 이에 본 연구에서는 이와 같은 무선 통신 인프라를 바탕으로 센서-네트워크를 이용하여 농업·농촌시설의 현장맞춤형 돌발재해 경보감지체계를 개발하고자 한다. 이는 산지재해 감지 무선센서 및 하천 수위센서를 개발하고, 무선으로 정보를 수집하는 게이트웨이를 경유하여 중앙의 정보수집센터로 수집 및 분석되며, 최종적으로는 지역주민들에게 사이렌 및 문자메시지 전송 등의 다양한 매체를 통하여 조기경보를 달성할 수 있는 체계를 구축하고자 한다.

This study aims to effective survey on actual condition for impact and vulnerability assessment on climate change in agriculture and rural community (limited to rural water and agricultural infrastructure, Paragraph 3, Article 2 of the Rearrangement of Agricultural and Fishing Villages Act) entrusted to Korea Rural Community Corporation based on the Law (Paragraph 2, Article 47 of the Framework Act on Agriculture, Rural community and Food industry). The results are summarized as follows. The rural water was divided into three categories (abnormal climate, water use, and flood control), and 31 indicators were selected. The reservoirs were divided into four categories, and 20 indicators were selected. The pumping stations were divided into two categories, 7 indicators, and the drainage pump stations were divided into two categories, 5 indicators were chosen. A survey on actual condition of each indicator was conducted and the result of the impact assessment was calculated. The 65 rural water showed values ranged from 0.855 to 1.308. The reservoir ranged from 0.966 to 23.338 as a result of the impact assessment on the 16 indicators. The pumping station was able to calculate the results of the safety inspection and the thorough safety inspection, and the drainage pump station was able to calculate only the result of the safety inspection. It is judged that it will be necessary to secure and analyze data on indicators with no data in the future. The results of this research can be utilized as baseline data that can deal with climate change preemptively.

The fabrication method of scintillator panel for digital radiography is proposed and demonstrated. The micro pixel structures were fabricated by DRIE(Deep Reactive Ion Etching) process and the scintillator was filled in the micro pixel structures using doctor blade. The micro pixel structures prevent the scattered visible light from spreading to neighboring pixels. The experimental results of X-ray image verified that the scintillator panel with smaller pixel size has better spatial resolution.

Analysis and evaluation of uncertainty is adopting the advanced methodology among the methods for greenhouse gas emission assessment that was defined in GPS2000 (Good practice guideline 2000) and GPG-LULUCF (GPG Land Use, Land-Use Change and Forestry). In 2006 IPCC guideline, two approaches are suggested to explain the uncertainty for each section with a national net emission and a prediction value on uncertainty as follows; 1) Spread sheet calculation based on the error propagation algorithm that was simplified with some assumptions, and 2) Monte carlo simulation that can be utilized in general purposes. There are few researches on the agricultural field including greenhouse gas emission that is generated from livestock and cultivation lands due to lack of information for statistic data, emission coefficient, and complicated emission formula. The main objective of this study is to suggest an evaluation method for the uncertainty of greenhouse gas emission in agricultural field by means of intercomparison of the prediction value on uncertainties which were estimated by spread sheet calculation and monte carlo simulation. A statistic analysis for probability density function for uncertainty of emission rate was carried out by targeting livestock intestinal fermentation, excrements treatment, and direct/indirect emission from agricultural lands and rice cultivation. It was suggested to minimize uncertainty by means of extraction of emission coefficient according to each targeting section.
