Agricultural environmental policies to reduce negative externalities and expand positive externalities became common around the world. However, literature regarding the efficient and effective implementation of agricultural environmental policies, such as optional direct payment, is limited. This study, thus, analyzes the relative importance for target selecting-criteria in order to enhance the cost-effectiveness of the Agricultural Environment Conservation Program in Korea. In this context, we conducted survey to 15 experts who are related in agricultural environment policies and analyzed survey results based on ANP method which can consider correlation between selecting criteria. The results show that, in the case field, "soil", "water", and "ecology" field have relative high importance than the other fields. Also, the relative importance for 'improving rural landscape', 'giving nutrient input moderately', and 'conserving agricultural heritage' activities is higher than the other activities. Furthermore, the relative importance among fields and activities of ANP is different from those of AHP. This result implies that it is necessary to consider the correlation between selecting criteria in order to design effectively. Finally, we suggest that in order to enhance the effectiveness of the program, it would be appropriate to assign differential points according to the importance of each activity when identifying appropriate farms.

EYM (European Yield Model), which was adopted in NDS (National Design Specification for wood construction), has been used in Korea without any verification of the analysis of bolted wood connections. In the case of applying lumber from domestic small diameter logs, however, there are some problems with the direct application of EYM ; 1) relatively low dowel bearing strength and dimensional stability due to a large amount of immature wood, 2) effect of MC (moisture contents) on the dowel bearing strength of wood and the yield load of a bolted connection. To evaluate the strength properties of bolted connections with lumber from domestic small diameter logs, effect of MC on the dowel bearing strength of wood was investigated and double shear bolted connection tests were performed. As the MC of wood increased, the dowel bearing strength was linearly reduced, even under 19% MC, which showed that adjustment, not considered in NDS, was required. Double shear bolted connection tests indicated that effect of MC on yield load should be considered in order to determine design value.

Most of eco-friendly agrifood processing enterprises in Korean rural area are small and medium-sized business. For this reason, it's hard for eco-friendly agrifood processing enterprises to neither analyze business performance for efficient business management nor establish their own business plan for rational decision-making. Therefore it's necessary to design effective mathematical programming model and to make practical application which can support rational management decision-making ensuring the stable business activity of eco-friendly agrifood processing enterprises. Accordingly this paper focuses on the designing and its application of multi-objective mathematical programming model using goal programming to support rational decision-making of eco-friendly agrifood processing enterprise. Hansalimanseongmachum Food Inc. which runs soy bean processing business making tofu based on regional-based soybean farms around Anseong City will be the specific case to apply multi-objective mathematical programming model in practice. And it will suggest measures to support rational management decision-making of other eco-friendly agrifood processing enterprises.

Volunteerism, as one type of citizen participation, can help local governments to cut down administrative expenditure and contribute to rasing of democratic consciousness in community. In this study, researchers examined the practical use of volunteerism in America. And discussed diverse incentives to voluntary service and rewards for volunteers. Local governments in Korea have suffered under lack of human resource and public finance. By positive introduction of volunteerism, they may obtain the desired results.

IT convergence with agriculture is expected to bring more efficiency and quality improvement in producing, distributing, consuming of agricultural products with the aid of information processing and autonomous control technologies of the IT area. In this paper, it is required to consider the actualized IT convergence case for agriculture, namely Smart Farming as a solution to cope the presented problems. In addition, suggest to standard functional model and standardization items for the smart farming based on network.

본 연구는 1992년도 브라질에 개최되는 국제환경회의에 UNDP의 요청에 의하여 이루어진 것이다. 한국의 유기농민단체들 가운데에서 화학비료와 농약을 전혀 사용하지 않고 영농을 경영하고 있는 정농회의 역사적인 발전과정을 조사하여 보았다. 그리고 정농회 회원들에 의하여 생산된 유기농산물과 일반 농산물 사이에 가격수준을 비교하여 보았다. 아직도 유기농업에 종사하고 있는 회원수는 500여명에 달하고 있다. 그러나 핵심 구성원수는 50여명에 불과하다. 정농회는 약 17년의 역사를 가지고 있는 유기농민단체이다. 유기농산물의 가격수준은 일반농산물과 비교하여 약 20% 정도의 수준을 나타내고 있다. 그러나 유통과정에서 소비자들에게 직접 배달하여 주거나 또는 직판장에서 직판하고 있는 실정이다. 앞으로 한국의 유기농업을 발전시키기 위하여 좀더 많은 실증적인 연구가 이루어져야 할 것으로 기대하는 바이다.

This study was carried out to investigate the potential promise of Chamaecyparis obtusa oil as a natural antioxidant. C. obtusa oil and its fractions were subjected to screening for their antioxidant activities by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and ammonium thiocyanate method. In the first case, $IC_{50}$ value of the C. obtusa oil was determined as $40{\mu}{\ell}/m{\ell}$. At $0.5{\mu}{\ell}/m{\ell}$ concentration level, free radical scavenging effect of fraction G determined as 66.94% was the highest among the fractions of C. obtusa oil. In the ammonium thiocyanate method, essential oil of C. obtusa and its fraction C, D, and E showed activities of 72.0%, 71.2%, 71.9% and 71.1%, respectively. Fraction G, most active fraction, was mainly consisted of $\alpha$-terpineol, elemol, widdrol and $\alpha$-cadinol.
