The purpose of this study is to suggest structural model and analyze design factors for the development of small greenhouse standardization model. The average dimensions of small greenhouse desired by urban farmers were 3.3m in width, 1.9m in eaves height, 2.7m in ridge height, 5.7m in length. The cladding materials for small greenhouse were preferred to glass, PC board and plastic film, framework to aluminum alloy and steel, and heating method in electrical energy. In addition, it was analyzed that small greenhouses need to develop structural model by dividing them into entry-level type and high-level type. The roof type that was used for entry-level type was arch shape, framework was steel pipe, cladding material was plastic film. On the other hand, high-level type was used in even span or dutch light type, framework with square hollow steel, cladding materials with glass or PC board. In consideration of these findings and practicality, this study developed four types of small greenhouses. The width, eaves height, ridges height, and length of the small greenhouses of even span type, which were covered with 5mm thick glass and 6mm thick PC board were 3m, 2.2m, 2.9m, and 6m, respectively. The small greenhouse of dutch light type covered with 5mm thick glass was designed with 3.8m in with, 2.2m in eaves height, 2.9m in ridges height, and 6m in length. The width, eaves height, ridges height, and length of the arch shape small greenhouse covered with a 0.15mm PO film were 3m, 1.5m, 2.8m, and 6m, respectively.
1. 우즈베키스탄과 농업협력강화를 위한 유망분야로 제시된 체리산업은 우즈베키스탄 정부의 제조업 육성 정책과 연계되는 사업으로 고용창출 및 경제개발 지원 효과 등 우즈베키스탄 정부의 지원이 가능한 분야임. 2. 최근 우즈베키스탄 정부는 주스 원액 제조 등 가공 산업의 개발을 통해 제조업 육성 정책 마련하고, 수출 기업들에게 국제기준에 부합하는 GAP의 인증 취득을 독려하고 있어 향후 수출 증대를 통한 농산업 발전이 기대됨. 3. 우즈베키스탄의 체리 산업은 현지 진출한 기업의 관심 분야이나, 체리 수출시 우리나라 검역관이 파견되어 상주하는 비용 등을 우즈베키스탄 생산자가 부담해야 하는 등의 이유로 우리 정부의 적극적인 지원이 필요함. 4. 향후 대 우즈베키스탄과의 농산물 교역 확대를 위해서는 기술지원 뿐 아니라 생산, 유통, 검역, 수출 등 가치사슬 전반을 고려하여 양국 협력 사업의 지속가능성을 강화해야함.
세계 빈곤인구의 대부분은 농촌에 거주하면서 농업에 종사하는 소규모 농가의 구성원이다. 소농은 자원 동원력과 시장 교섭력이 취약하기 때문에 스스로의 힘으로 빈곤에서 탈출하기 쉽지 않다. 한편, 소농은 개도국의 농업발전과 농촌지역사회 유지에 중요한 역할을 하며, 식량안보 강화와 빈곤 퇴치를 위한 잠재력을 보유하고 있다. 이러한 잠재력을 발휘하기 위해서는 소농의 농업부문에 대한 투자가 원활하게 이루어져야 하고, 생산-가공-유통으로 이어지는 농업의 가치사슬이 형성되어야 한다.
본 논문에서는 농업협동조합 모델을 그 대안으로 제시하였다. 특히 정부의 적극적인 개입과 지원 하에 금융서비스를 포함한 종합적 서비스를 제공함으로써 농업·농촌발전에 큰 공헌을 한 한국형 농업협동조합에 착안하여 ODA 적용방안을 모색하였다. 그리고 최근 농업협동조합법 제정을 앞두고 있는 라오스의 농업 생산, 농산물 시장접근성, 조직화 수준, 농업 금융시스템 등 농업협동조합 설립 여건을 고려하여 ODA 프로그램 모델을 수립하였다. 즉, 조직화를 중심축으로 하고 생산성 향상, 시장접근성 제고, 금융서비스 제공을 주요 내용으로 한 농업협동조합 ODA 프로그램 모델을 제안하였다.
본 연구에서는 정밀농업 구현을 위해 필수적인 요소인 토양과 기후 그리고 위치요인을 데이터로 구축한 후 이를 수치화하여 최고점수제를 이용하는 지식기반형 작물추천모델을 개발하였다.
작물추천시스템에서 사용한 요인은 토양과 기후 그리고 위치정보이다. 토양의 경우에는 흙토람 자료 중 작물적지 선정에 80%이상 활용되는 토성, 침식등급, 배수등급, 경사, 자갈함량, pH를 선정하였다. 기후요인은 기상청의 5년간 누적데이터를 기초로 하여 작물생육에 필수적인 기온과 강수량 그리고일조시간 등을 사용하였다. 위치정보는 한국토지정보시스템과 수치지형도를 가공하여 사용하였다. 예시작물은 농촌진흥청에서 추천한 옥수수, 유채, 갈대, 수박, 고추, 토마토, 양파, 감자, 고구마, 구기자 10개 작물로 하였으며, 향후 작물추천 수요가증가할 것으로 예상되는 제천, 무안, 원주, 함안 4개 지역을 포괄적으로 시뮬레이션하였다. 분석결과 평균점수는 고추가 75.5점으로 가장 높았으며 고구마가 61.2점으로 가장 낮았다. 작물별 식재면적에 제약이 있다고 가정하고 2차 시뮬레이션을실시하여 경남 함안시의 7만 필지를 별도설정하고 분석한 결과 고구마가 39,190필지에서 가장 높은 점수를 받았으며 면적으로는 27.014 km2이었다.
지식기반형 작물추천시스템은 작물의 적지를 선정하는 항목과 가중치가 검증되지 않았다는 한계를 가지고 있으나, 이에 대한 보완이 이루어지고, 농산물유통부분을 고려하여 실제 정보수요자에게 제공하면 영농현장에서 활용 가능할 것으로 판단한다.
이 연구에서는 최근 농림수산식품부를 중심으로 추진되고 있는 농업·농촌부문 국제협력사업의 규모 및 협력 대상지역등을 분석하여 우리나라가 전수할 수 있는 경험, 기술의 목록(안)을 작성하여 제시하였다. 농업·농촌부문에서 적용할 수있는 국제협력 모델 수립을 위하여 이들 경험과 기술을 기초로 한 원조 프로그램을 7가지로 정리하여 제시하였다. 원조 프로그램은 미곡 생산성 증대 및 산업화 체계 구축, 원예작물생산성 증대 및 산업화 체계 구축, 축산업 발전체계 구축, 농업 인프라 구축, 농업기술 개발 및 보급, 지도, 농촌종합개발,그리고 농업정책 종합 컨설팅 등이다. 협력사업은 역량개발,컨설팅, 시설장비물자와 같은 현물지원 등 세 가지의 형태로구분하여 제시하였다. 원조 프로그램이 협력사업으로 추진되는 경우의 추진 주체는 정부와 민간부문(기업, NGO), 국제사회 등으로 효과적인 역할 분담과 원조조화성이 강조되어야 한다. 농업·농촌부문에서의 추진주체간 협력형태는 “선진화 방안”의 표준 “원조모델”을 참고하여 정부-NGO간 협력 사업 형태, 정부-기업간 협력 사업 형태, 정부-국제사회간 협력 사업형태로 설정되어야 할 것이다.
정부가 추진하는 국제개발협력 “선진화 방안”에 부응하여농업·농촌부문에서 협력대상국에 적용 가능한 개발경험과 사업기술 항목들을 발굴, 선정함으로써 국가 전체의 개발협력 기본방향에 부합할 수 있을 것이다. 또한 이들 개발경험과 사업기술 항목들을 참고하여 대상국의 요청에 맞는 세부 사업내용을 협의함으로써 농업·농촌부문 협력사업의 효율적인 추진이 가능하게 될 것이다. 그리고 이 연구를 통해 농식품부와소속기관에게 원조 프로그램과 추진주체의 역할 및 협력형태등에 대한 기본적인 모델을 제공함으로써 사업간 조정능력이 제고되고 사업추진의 효율성이 높아질 것으로 기대된다.
농업·농촌부문에서 협력대상국은 우리나라의 개발경험과 사업기술 및 이를 토대로 수립된 협력 모델을 근거로 하고, 또한 자체 개발전략과 공여국기구의 국별협력전략 등을 참고하여 적합한 사업을 선정할 수 있게 됨으로써 보다 신속하고 체계적인 맞춤형 협력사업이 추진되어야 할 것이다. 끝으로, 선정된 경험, 사업기술을 중심으로 협력사업이 추진될 경우 관련인력, 조직기관의 역량이 제고되어 지속가능한 사업이 될 수있게 하는 것이 향후 협력대상국의 농업·농촌부문에서 나타나고 있는 문제점을 해결하는데 도움이 될 수 있을 것이다.

The aims of this paper is to develop a modular agricultural robot and its autonomous driving algorithm that can be used in field farming. Actually, it is difficult to develop a controller for autonomous agricultural robot that transforming their dynamic characteristics by installation of machine modules. So we develop for the model based control algorithm of rotary machine connected to agricultural robot. Autonomous control algorithm of agricultural robot consists of the path control, velocity control, orientation control. To verify the developed algorithm, we used to analytical techniques that have the advantage of reducing development time and risks. The model is formulated based on the multibody dynamics methods for high accuracy. Their model parameters get from the design parameter and real constructed data. Then we developed the co-simulation that is combined between the multibody dynamics model and control model using the ADAMS and Matlab simulink programs. Using the developed model, we carried out various dynamics simulation in the several rotation speed of blades.
The aim of our study was to provide a basic data for the development of a small greenhouse model suitable for urban farmers. The study analyzed installation inclination, positive and negative reasons for installation, location of installation, preferred crops in small greenhouses, plans for use of products, and expected effects by using small greenhouse. Positive opinion on small greenhouse installation was 80.4% of the survey respondents. The most positive reason for the installation of small greenhouses was fresh and safe food supply, and the negative reason was maintenance difficulties. The results obtained in our survey indicated that small greenhouses were more likely to be installed near the house, and urban farmers tended to grow organic leafy vegetables in soil. The expected benefits of small greenhouse operation were largely divided into ‘benefit for the improvement of the quality of life’ and ‘benefit for economic profits’, and expectation for the improvement of the quality of life was higher than economic benefit. As a result of the Likert 5-point scale analysis, ‘benefit for the improvement of the quality of life’ by using a small greenhouse was graded as high as 4.17∼4.60. On the other hand, the ‘benefit to economic profits’ was rated as low as 3.51∼4.14.
This study was in line with consecutive growth of urban agriculture implemented to provide a functional vegetable garden model for urban vegetable gardeners. It targeted the users who actually raise functional vegetable gardens, analyzed the flaws for correction in many ways including a type of products, quantity, ratio, and the like and existing problems. It is found out from Utilization that first is the highest ranking with no experience of growing vegetable garden education while growth education helping vegetable garden activity takes the half. Saying yes to the participation in the growth education following the process ranked the highest. In addition when planting, in regards to earning information about plantation timing and measure, they responded that they directly determine those by themselves. Second, the type of plant that they are mainly supposed to produce in family gardening was vegetables. Many say that it is easy to produce, easy to get information. In the fall, Kimchi and vegetables ranked the highest, the reason for functional vegetable gardeners to participate in planting family garden is an interest in a variety of producing crops. Third, the current amount included is proper for flower・herb plants in functional vegetable garden model while the ratio of crops vegetables60.5 : medical21.2 : flower・herbs18.3 in vegetable garden model is responded moderate.
The estimation of groundwater usage in Jeju island is important to understand hydrologic cycle system and to plan management of water resource because large amounts of groundwater have been used for agricultural and domestic purpose. The model has been developed to estimate agricultural groundwater usage for garlic at uplands and citrus at orchards raising outdoors using the soil water balance model from FAO 56, respectively. The total amount of water supplied for the crop evapotranspiration and the multipurpose function such as sprout promotion can be simulated by the model. However, due to the discrepancy of water use in initial stage between calculated and observed, the model was calibrated and verified using actual groundwater usage monitoring data for 3.5 years (2011.6 to 2014.12) at three uplands for garlic and three orchards for citrus. Consequently, it would be concluded that the model simulated efficiently actual water usage in that root mean square (RMS) and normalized RMS of the validation stage were less than 8.99 mm and 2.43%, respectively, in two different conditions.
The key objective of this study was to evaluate trophic state and empirical water quality models along with analysis of fish trophic guilds in relation to water chemistry (N, P). Trophic state index (TSI), based on total phosphorus (TP) and chlorophyll-a (CHL), ranged between oligotrophic and hypereutrophic state, by the criteria of Nürnberg(1996), and was lower than the trophic state of total nitrogen (TN). Trophic relations of Secchi depth (SD), TN, TP, and CHL were compared using an empirical models of premonsoon (Pr), monsoon (Mo), and postmonsoon (Po). The model analysis indicated that the variation in water transparency of Secchi depth (SD) was largely accounted (p < 0.001, range of R2 : 0.76–0.80) by TP during the seasons of Mo and Po and that the variation of CHL was accounted (p < 0.001, R2 = 0.70) up to 70% by TP during the Po season. The eutrophication tendency, based on the TSITP vs. TSIN:P were predictable (R2 ranged 0.85–0.90, p < 0.001), slope and y intercept indicated low seasonal variability. In the mean time, TSIN:P vs. TSICHL had a monsoon seasonality in relation to values of TSIN:P during the monsoon season due to a dilution of reservoir waters by strong monsoon rainfall. Trophic compositions of reservoir fish reflected ambient contents of TN, TP, and CHL in the reservoir waters. Thus, the proportions of omnivore fish increased with greater trophic conditions of TP, TN and CHL and the proportions of insectivore fish decreased with greater trophic conditions.
To revitalize rural economy and to generate job opportunities in the Korean countryside through the specialized production of high-valued/environment-friendly farm products and the active promotion of green tourism in the farmland-remodelling project sites in 4 main riverside areas, this study developed the regionally differentiated development models of future-oriented agri-business complex. Through two rounds' expert group consulting/checking, related literatures review and similar case-projects benchmarking, a tentative model system was made and corrected, and finally, 6-development types with 24 model complexes proposed.
We need fundamental plan to develop Environment-friendly agriculture which has essential effect to agriculture and rural community. It should be avoided the structural problem that the farming corporations has gone through in present. Firstly, it needs to be systematized and constructed farming complex for the priority. The government initiated Environment-friendly agriculture business and expanded agriculture business as the part of the policy. There are some researches which have been studied the systematization and the construction of farming complex. It is suggested and mentioned various kinds of policies and directions so far. But, it is not mentioned any practical models. That means it seems to be various differences between each farming corporations in the structural cases. This research suggests the most optimized model of Environment-friendly agriculture by analyzing structural differences between ‘Natur’ farming Corp and ‘Sancheong-gun’ expanded Environment-friendly farming complex.
The green craze has hit all the world lately. The green revolution which means immense changes for sustainable development under the new environment-economy system is foretelling that we should have new angle to the environment and economy. This paper is about the development of the model and indicators for construction of ECO(Energy Circulating Organic)-Village which is the green growth option of local community. This model is composed of three concepts - SPDC (about procedural methodology of Model), Virtuous Circle (about functional relationships of three requisites), Network (about spatial relationships between communities) - and evaluation indicators. Environment, tourism, industry (Energy & Organic Agriculture) are set as the three requisites for green growth of local community. Nations of the world plunge into the green war which is silent, general, sweeping changes. We can not win this war with the existing thinking system and policy. We need revolutionary changes reconsidering of environmental value and sustainable development strategy of the region. Each of us should go through the changes and this work would be the one among those efforts.
Customary agriculture seeks to increase production and supply people with safe foods. Thus, the promotion and establishment of organic agriculture are required to reduce water and soil pollution caused by customary agriculture.
Although organic agriculture is an agricultural technology system whose basic principle is organic water circulation in agronomic agriculture and livestock industry, the livestock raising sector has not been developed in Korean organic agriculture;hence the limited development of agronomic agriculture. This study therefore sought to develop a standardized model connected with organic livestock raising and organic agronomic agriculture to secure symmetric and continued development. Specifically, this study reviewed the technological and economic problems related to the development of a naturally circular standard model where organic agronomic agriculture and organic livestock raising are connected. Likewise, a model for calculating the appropriate quantity of fertilizers to be applied and appropriate number of livestock to be bred was proposed as important factors in the development of a regionally circular agriculture model, and an alternative to a system connecting the two factors suggested.
