This study aimed to investigate the effect of treating environmental purification insect larvae to pig manure on crude ash contents and ammonia production. The experiment set up consisted go two groups: 1 kg of each 3rd instar TM (Tenebrio molitor) and 3rd instar PBS (Protaetia brevitarsis seulensis) larvae in Experiment 1 or 3rd and 4th instar of HI (Hermetia illucens L.) larvae in Experiment 2 were treated with 5 kg of pig manure. In Experiment 1, the crude ash content was higher in TM larvae-treated pig manure at days 0 and 5 (p>0.05), but was similar to that in PBS larvae-treated pig manure over (p>0.05). Ammonia production was observed at day 0 of TM and PBS larvae-treated pig manure (p<0.05), but did not occur thereafter. For Experiment 2, there was significant difference in crude ash content of 3th and 4th instar HI larvae-treated pig manure on day 15. Additionally, ammonia production was found in 3th and 4th instar HI larvae-treated pig manure at days 0 and 5, but did not continue over time. In conclusion, treating TM, PBS and HI to pig manure changed the crude ash contents and reduced ammonia through the ability to decompose pig manure. Thus, environmental impact can be minimized using environmental purification insect larvae.

The objective of this study is to propose a development method and a political theme of environmental silvipolis as a new alternative to mountain-village development. For mountain village to be environment-friendly area which is surrounded by clean water, fresh air, and thick forest, the development of sivipolis in a way that people are harmonized with forest is based on the followings; 1) fixing a policy direction of that gradually with a changing trend of society, 2) improving legal and executive support system including a legislation of the law of silvipolis development, 3) setting up the guideline of the policy and introducing an incentive scheme at the action plan, and 4) identifying the main body and the method of silvipolis development.

The purpose of this study is to figure out the necessity of forest insurance, by surveying forest insurance related questionnaires such as understanding of forest disaster control systems, preference of forest insurance types, and willingness to buy the insurance for forest owners. Therefore, this study can present the basic information for establishing a new forest insurance market. The willingness to buy the insurance for forest owners estimated by logit model and probit model. The result is shown that the older forest owner and group forest owner the probability of willingness to buy the insurance is decreased. But, In the case of more government subside to forest insurance payment, larger forest owner the probability of willingness to buy the forest insurance is increased.

국민의 건강과 웰빙에 대한 관심 증대 및 소득 증가로 한약재 소비를 비롯한 식품과 화장품 원료로서의 산업적 가치가 커지면서 약용작물의 수요는 점차 증가할 것으로 예상하며 한, 중 FTA 체결로 인해 약용작물 시장개방의 수입증가는 위협요인으로 작용할 것이다. 그러한 측면에서 약용작물을 포함한 농식품산업을 미래 성장 동력산업으로 육성하기 위해서는 종자품종육성과 생산유통기반의 정비와 확충, 산지이용규제 완화 등의 다양한 대책이 마련되어야 한다. 본 연구 결과의 활용방안을 살펴보면 다음과 같다. 첫째, 국가의 약용산업 육성 중장기 전략과 종자관리체계의 구축에 필요한 약용작물의 데이터베이스를 구축하고 향후 개발해야 할 중점기술을 제시해야 한다. 둘째, 우수한 약용작물 품종 개발 및 보급으로 농업생산성을 높여야 한다. 셋째, 약용작물 종자생산 및 보급에 필요한 제도정비가 필요하다. 넷째, 우량종자의 표준화 및 규격화로 약용작물의 생산유통체계를 확립해야 한다. 현재 약용작물의 소비행태는 직접적인 섭취보다 화장품, 의약품, 식품의 형태로 소비되는 패턴으로 바뀌고 있으며 규모가 점점 확대될 것으로 전망된다. 그러므로 향후 약용작물의 생산에서는 이러한 산업화 추세와 변화에 대응한 정책개발과 제도적인 개선이 뒷받침되어야 한다. Increasing concern for the health, well-being, and income of the people has expectedly brought continuous increase in the industrial value of medicinal plants in recent years as these are also used in foods and cosmetics. However, Korea's increased import of these products from China due to the FTA contract causes negative effects on its industrial value. In this regard, various measures for medicinal crop seed development and production, organization and expansion of circulation and forest land use deregulation are needed to promote the agricultural food industry including medicinal plants. As a measure, first, a database of medicinal plants should be built that can help to promote the national medicinal industry and the seed management system. Second, agricultural productivity should be enhanced via the development and supply of varieties of high quality medicinal plants. Third, there should be a good practice of the system maintenance for the production and supply of medicinal crop seeds. Fourth, production and distribution system of medicinal plants should be established by standardization of high quality seeds. Nowadays, the consumption pattern of medicinal crops is changing from direct ingestion to cosmetics, drugs, and food and this is expected to increase continuously. Consequently, the increased production of medicinal crops will support the development policy and the institutional improvement in response to this trend of the positive change of industrialization.

The purpose of this study is to examine the aspect and characteristics of conflict among the people in the rural tourism villages shown in the course of conducting a joint project and managing a business. This study was undertaken in view of the ground theory, which includes the stage of research design, collection and analysis of information, and assessment in reliability of the study. There were 3 stages of conflict: the source, the expression and the result of this conflict. As the stage of business propulsion and the stage of business operation, the aspect of conflict in the agricultural joint business was different. The result of conflict was not only in the point of negative but also in the point of positive. Additionally, systematic management of conflict among the people in an agricultural joint business should be conducted.
