최근 농경지 투입양분으로 인한 환경영향의 우려와 함께 하천 등으로 유출되는 양분의 오염부하 관리가 요구되고 있다. 이에 정부는 국내 농지의 양분 과잉 투입 문제를 해결하기 위해 농경지의 양분관리 목표를 설정하여 관리하는 양분관리제도의 도입을 추진하고 있다. 본 연구는 국내 합리적인 양분관리제도 도입을 위한 양분관리 지표 기준을 설정하고자 도 단위의 양분부하와 양분수지 지표를 분석하고 지표별 특성을 비교 검토하였다. 도 단위 질소와 인성분의 양분부하와 양분수지 분석에서 지역별 양분 부하 순위와 양분수지 순위가 다르게 나타나, 지역의 양분 수준을 평가하는데 있어 양분부하와 양분수지의 두 지표는 서로 상이한 지표 값을 도출하는 것으로 나타났다. 양분부하와 양분수지 간의 상관관계 분석에서 질소성분의 경우 상관관계 계수 (r)는 0.2504로서 5% 유의수준에서 통계적 유의성이 없었으며, 인성분의 경우 상관관계 계수 (r) 가 0.7375로서 5% 유의수준에서 통계적 유의성이 인정되었다. 따라서 양분관리 지표활용에 있어 인성분의 경우 양분부하와 양분수지 간의 상호 호환성이 나타났으나, 질소 성분의 경우 양분부하와 양분수지 간의 상호 호환성이 없는 것으로 나타났다. 따라서 지역의 양분관리 지표로서 농업환경 특성을 반영하는 양분수지 지표의 활용이 합리적인 것으로 평가되었다.

This experiment was carried out to determine the treatment interval on neem product for control of Bemisia tabaci on eggplant using eco-friendly agriculture. We have investigated the control effect of B. tabaci, growth characteristics of eggplant, economics according to neem product treatment interval on eggplant. The longer neem processing interval tended to decrease control effect on nymphs of B. tabaci. Control effect of nymph of B. tabaci according to treatment interval of 3 days, 5 days, 7 days, 10 days, and 15 days were 96.7%, 89.7%, 76.1%, 73.4%, and 51.0%, respectively. This result was the same tendency in adult of B. tabaci control effects on eggplant. Growth characteristics of eggplant according to neem the treatment interval of 3 days, 5 days, and 7 days, was less damaged on of B. tabaci. However, the 10 days, 15 days, and untreated of neem treatment intervals were badly damaged by B. tabaci. Therefore, neem treatment interval of 3~7 days for control of B. tabaci was high control effect. However, it is considered to be the most suitable to process every seven days considering the economics and so on. The results of economic analysis from income of 7 days neem treatment interval was the most high as 19.505 thousand won per 10a and the most economical treatment for control of B. tabaci.

The main purpose of the research is to suggest a new business model of direct distribution of organic agricultural products cultivated in suburban area. To secure competitiveness, logistics cost reduction is important through direct transaction of organic agricultural products cultivated on suburban area. The research addresses food safety, farmers' income and unemployment issues with Eco-M business model. The research methods include investigation on the followings: current domestic agriculture; related problems on the existing literature reviews; the current status of suburban agriculture; specialty store of eco-friendly agricultural products. Eco-M business model can solve various problems of suburban agriculture supply system, challenges of organic farming specialty stores, unemployment issues, and difficulties of processing verticalization. Future research should include followings. First, there should be comparative analysis between businesses of environmentfriendly specialty stores through suburban agriculture and producer's agriculture connected with organic farming market. Second, it is required to develop strategy of environment-friendly specialty stores. Finally, analysis of the potential of Sextic industries is necessary throughout production-process-service process.

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.
