The price of agricultural products has changed from year to year, the m ajor c ause o f price fluctuation is the imbalance of supply and demand. Materials which are mainly used in korean cabbage production volume is the forecast model, using the cadastral result, slope calculation is impossible to achieved. For this reason, this implies the drastic decrease of prices and the prediction of supply and demand of field crops that is cultivated in a highland slope area, this situation is being repeated. Therefore, the target area of this research is the slopes of high land, by using 2D and 3D Lidar data for the analysis of the cultivated area. Experiment was carried out in the same area to compare the data differences. The rate of change in the area of slope is quantitatively increasing presented by the regression model. An alternative methodology that can improve the reliability of the calculated slope area using 2D is through cadastral map.

강우가 발생하거나 관개를 함에 따라 농경지의 토양침식물, 잔류 비료나 농약 등의 비점오염원은 지표 및 지하 유출과 함께 거동함으로써 지표수 뿐 아니라 지하수 수질에도 영향을 미칠 수 있다. 특히, 최근 고부가가치 농산물 수요의 증가로 전국적으로 시설재배 농업이 확대되고 있으나 시설재배 내에서의 비점오염원 유출특성에 관한 연구는 미흡하다. 따라서 시설재배 농업과 관행농업의 비점오염원의 거동 및 지하침투 오염부하를 비교 평가하고 비점오염원을 저감하기 위한 적절한 방안 마련이 필요하다. 따라서 본 연구에서는 시설 및 관행재배 지역의 지하침투 오염부하량을 평가하기 위하여 주변 영향이 배제되어 시설재배와 관행재배의 비교 평가 가능한 포장 및 광역 단위 시험포장을 선정하고 모니터링 시스템을 구축하였다. 먼저 필지 단위와 광역 단위 단위에서의 모니터링 시스템을 설계하고, 수문 및 수질 분석 항목을 설정하였다. 이를 바탕으로 관행재배지에서의 물수지 모니터링을 위하여 기상 및 강우량, 지하수위, 토양수분, 관개 및 배수량을 측정하기 위한 장비를 설치하고, 토양수 및 지하수의 물질 수지 분석을 분석하기 위한 토양수, 지하수, 논담수 등의 수질 샘플망을 구축하였다. 또한 시설재배지에서의 물수지 모니터링을 위하여 기상, 지하수위, 토양수분 및 관개량을 측정하기 위한 장비를 설치하고, 토양수 및 지하수의 물질 수지 분석을 분석하기 위한 토양수, 지하수, 관개용수 등의 수질 샘플망을 구축하였다. 향후 본 시험 포장에 대한 지속적인 모니터링과 샘플링 실시하여 다양한 항목에 대한 조사 및 분석이 이루어진 다면 시설재배지 비점오염원 모니터링 및 정량화 기술개발을 통해 시설재배지에서의 비점오염에 대한 정량적 자료구축이 가능할 것으로 판단되며, 기초적인 자료를 제공함으로써 국내 농업비점오염총량 추정 기술에 기여할 수 있을 것으로 판단된다.

유기농업은 저농약, 무농약, 자연농법과 함께 환경 친화적 농업으로 인식되어 세계적으로 유기농산물 생산량 및 재배면적이 급격하게 증가하고 있다. 국내 역시 안전한 먹거리 생산과 재배환경에서의 유해물질 관리방안 구축 등이 필요한 상황이다. 자가생산 유기농자재, 가축분을 이용한 축분 퇴비와 액비, 그리고 유박 등이 유기농업에 활용되고 있으나 사용 유기농자재의 양분가용화와 양분이용효율에 따른 비점오염원 형태로 토양 및 수질에 미치는 환경영향 등의 관측과 분석이 필요한 실정이다. 따라서 본 연구의 목적은 밭 포장에서의 유기농업 적용에 따른 유기농과 관행농에서의 대표적 비점오염원인 영양물질(T-N 및 T-P)에 대한 원단위를 평가하는데 있다. 시험포장은 전북 순장군 순창읍에 위치하고 있으며, 유기질비료시비 및 관행작물(고구마)의 3반복 1처리구(경사도 $6.6^{\circ}$)와 관행농관리 및 관행작물(고구마)의 1반복 1대조구(경사도 $6.8^{\circ}$)로 구성하였다. 현장에서 강우량과 유량을 실측하였으며, 강우 이벤트 시 T-N 및 T-P의 수질항목을 샘플링 후 분석하였다. 2016년 현재까지 총 6회의 강우 이벤트가 발생하였으며, 그 중 4회의 수질 샘플링을 실시하였다. 유출률은 평균 유기농에서 32%와 관행농에서 57%로 나타났다. 이는 토지피복 및 선행강우 등의 영향으로 다양한 분포를 보여주었다. 유기농 처리구에서 수질 부하량이 전체적으로 높게 나타났으며, T-N의 경우 4.4배와 T-P의 경우 1.8배로 나타났다. 이러한 경향은 유출수의 농도 영향보다 유출량의 영향이 큰 것으로 보인다. 유기농 처리구의 경우 제초제 등의 농작업이 제대로 이루어지지 않아 조도계수가 높았으며, 유기농 처리구에서 유출량이 31% 수준으로 상대적으로 낮게 나타났다. 본 연구의 경우 관행적으로 이루어지는 제초관리 형태를 벗어난 경우로 일반적인 결론 도출에는 한계가 있으나 유기농업 경작지에서 일반적으로 식생분포가 활발한 특성을 보여주고 있다. 향후 추가적인 모니터링 연구가 지속적으로 필요하며, 본 연구를 바탕으로 유기농업 최적관리방안 제시에 필요한 기초자료로 활용되기를 기대된다.

Development of synthetic vinegar has been focused on the acidic taste typically caused by acetic acid. Recently, consumer interest in fermented vinegars which contain a variety of valuable nutrients increased growth of the beverage industry. Vinegar beverages made of a variety of foreign fruits such as pineapple, grapefruit, and aloe are being commercialized to meet market needs from female consumers interested in beauty. However, commercialization of traditional fermented vinegars using regional products such as rice has not been successful yet compared to fruit vinegar beverages. Systematic research for development and commercialization of functional value-added traditional vinegars made of regional agricultural products should be performed. In this study, type and manufacturing methods of traditional vinegar were reviewed based on classic literatures.

This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using local foods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and web documents before (from January 2016 to December 2019) and after (from January 2020 to November 2022) the COVID-19 outbreak. TF-IDF analysis showed that 'Trend', 'Market', 'Consumption', and 'Food service industry' were the major keywords before the COVID-19 outbreak, whereas 'Wanju-gun', 'Distribution', 'Development', and 'Meal-kit' were main keywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after the COVID-19 outbreak, the 'Market' category included 'Non-face-to-face market' instead of 'Event,' and 'Delivery' instead of 'Distribution'. In the 'Product' category, 'Marketing' was included instead of 'Trend'. Additionally, in the 'Support' category, 'Start-up' and 'School food service' appeared as new topics after the COVID-19 outbreak. In conclusion, this study showed that meaningful change had occurred in market issues on HMR using local foods after the COVID-19 outbreak. Therefore, governments should take advantage of such market opportunity by implementing policy and programs to promote the development and marketing of HMR using local foods.

The purpose of this study is to establish and propose a post-diagnosis checklist for the revitalization of domestic regional co-brands that have not been activated despite many strengths. First, I looked into the brand revitalization methodology through prior researches and among them, referring to the cause-remedies model, the cause of the deactivation of the co-brand and the currently used revitalization method were examined through case studies and expert interviews. Regarding the currently used method, the reason for using the method was inferred, and the factors corresponding to the cause and effect were found and categorized in the inferred sentence, and the corresponding detailed items were set and the checklist items were presented. Although this study has a limitation in that there is no practical checklist verification, it is expected that a specific activation plan will be presented through verification of future studies.

While the integration into global value chains has garnered attention as a rural development strategy, less is known about why some integrations are successful while others are not. This study draws on rent theory and on empirical examples from Jinju and Nonsan, the two biggest strawberry production regions in South Korea, to explore the mechanisms of Jinju creating and exclusively retaining monopoly rents from the exports. Based on five months of fieldwork and in-depth interviews with stakeholders, the findings show that a producer-driven chain integration into the overseas markets was possible in Jinju due to the natural barriers to entry based on an exportable variety, as well as the region's climate conditions being suitable to the variety. Moreover, the farmers have attempted to retain the monopoly rents and extra profits from public supports by associating producers. The horizontally associated farmers stabilized their positions by enhancing their bargaining power against exporters, as well as by managing access to the public supports by controlling memberships.

To investigate the germanium content in paddy soil in Gyeongnam province, 310 paddy soil samples were collected at 19 areas in Gyeongnam, Ulsan and Busan. Contents of germanium in paddy soils were analyzed in different topographies, soil types and soil textures. Average content of germanium in Gyeongnam was 0.24 mr/kg, those of Masan, Jinju and Hadong were above 0.30 mg/kg. Germanium content with different topographies were no difference. Germanium contents in different soil types were 0.27 mg/kg in well adapted soil and 0.23 mg/kg in poorly drained soil. Germanium contents in different soil textures were 0.27 mg/kg in silt loam and 0.23 mg/kg in sandy loam. To determine germanium content on agricultural product in the field, content of germanium in cereals, vegetables and fruits were analyzed. Germanium content of agricultural product was high in the order of cereals>vegetables>fruits. In case of vegetables, germanium contents were high in the order of leaf vegetables>root vegetables>fruit vegetables. Germanium contents were high with 62 and $65{\mu}g/kg$ in lettuce and young radish, respectively. To analyze the germanium content in medicinal plant, samples were collected from 19 medicinal plants at Hamyang areas. Germanium contents in Angelica keiskei, Ligusticum chuanxiong, Panax ginseng and Atractylodes macrocephala were relatively high with $100{\mu}g/kg$ above.
