수직농업은 미래의 식량, 인구문제를 해결할 수 있는 농업 방식 중 중요한 농업 방식이다. 그러나 초기투자비용, 기술문제 등으로 인하여 저개발 국가에서는 진입에 어려움을 겪고 있다. 이러한 문제들을 해결하기 위하여 수직농업 도메인을 온톨로지로 정형화하는 것이 필요하다. 본 논문에서는 수직농업의 다양한 재배방식을 포함하고 그 방식에 따른 센서들과 액츄에이트의 연결 및 선택된 수직농업의 재배환경 컨텍스트를 인지하고 제어할 수 있는 온톨로지를 제시하였다. 우리는 온톨로지의 논리 추론 기능을 사용하여 인지된 수직 재배에 주요한 환경 컨텍스트를 분석함으로써 자율적으로 컨텍스트에 대한 제어 결정을 내릴 수 있을 것으로 기대한다.

This study was conducted to compare the community structure and biodiversity of epigeic spiders between pear fields cultivated by integrated pest management (IPM) and organic methods. This is the first study of this kind to be conducted in Korea. Eighty-four spider species from 22 families were identified among the collected 2,489 arthropods, with 754 individuals being sampled from IPM fields and 1,735 individuals from organic fields. Generally, Theridiidae, Linyphiidae, Lycosidae, Agelenidae, Gnaphosidae, and Salticidae were the dominant spider families in the pear orchard regardless of the farming methods, and species richness and abundance were higher in organic fields than in IPM fields. The dominant species were the wolf spiders (Lycosidae) and stone spiders (Gnaphosidae), and their cumulative abundance was 70.7% in IPM fields and 72.7% in organic fields. The community structure between organic and IPM fields was heterogeneous, with a 45% similarity level. Biodiversity, species richness, abundance, and species diversity index were higher in organic fields than in IPM fields, and significantly different between the farming methods. Seasonal fluctuations in biodiversity were similar in both IPM and organic fields. The species richness and species diversity index increased and the abundance decreased in the second half of the cultivation period. This study on the community structure and biodiversity of epigeic spiders, which form one of the most important predator groups, will provide principal ecological and faunistic information required to maintain the biodiversity of useful arthropods in agricultural ecosystems and help implement sustainable agriculture based on the active use of natural enemies.

The purposes of this study are to analyze the time use patterns of rice and barley for farm couples. The data used for this study were collected from farm households during the farming seasons (17th to 30th June) and the off-farming seasons (28th November to 11th December) of 2005, using a time diary. The sample for this study consisted of 118 couples, whose principal crops were rice and barley, living in rural area in eight provinces. SPSS Win 12.0 was utilized to analyze the data. The statistical methods used were frequency, percentage and paired t-test. The major findings of this study were as follows. First, the personal care time of wives was shorter than that of husbands, regardless of the fanning period, with the couples showing more personal care time during the off-farming season than during the farming season. Secondly, the total work(paid work plus housework) time of wives was longer than that of husbands during both the farming season and the off-farming season, showing that the labor burden of wives was bigger than that of husbands. Compared to the farming season, the total work time for both husbands and wives was shorter during the off-farming season, due to reduced farm work time, but the housework time increased for both husbands and wives. Thirdly, the leisure time of husbands was longer than that of wives during both seasons. The leisure time increased for both husbands and wives during the off-farming season, but the portion of the increase was bigger for husbands than for wives.

This study analyzes patent trends regarding farming-related technologies such as breeding or nursery technology, production systems, and new cultivation methods in order to provide objective patent information about the trends of R&D on marine products' proliferation or farming. Presently, in Korea, we try to secure marine living resources through the formation of artificial resources instead of environmental improvement policy or resource management policy. However, this is not about eliminating the causes of marine environment destruction but just the policy for improvement, so it is needed to revise the related policy with more ultimate measures. And it is necessary to develop technology that can secure the rights by integrating patent application strategies from the stage of R&D for medicine that can be utilized in chief farming countries and provide intensive support for the research centering around strategic varieties for farming in each region as well as strategic national farming varieties afterwards. Also, the analysis shows that it is urgent to make applications overseas based on domestic applications in order to develop technology that can be commercialized in not just Korean but overseas market as well.

기존의 예측 방법들은 과거의 통계적인 수치를 사용해서 미래를 예측했었다. 정확하게 농산물 가격을 예측하려면 정확한 지식과 많은 노력이 필요하다. 그러므로 이러한 문제점을 해결하기 위해서, 본 논문에서는 농산물 예측 가격을 향상하기 위해서 전처리로 퍼지 및 신경망을 사용하였다. 또한 후처리로써 예기치 못한 상황을 실시간으로 예측할 수 있는 지능형 농사 전문가시스템을 개발하였다. 시뮬레이션결과 제안된 농산물 가격 예측이 퍼지 규칙을 사용하지 않은 기존 수요예측 시스템보다 가격오차를 줄일 수 있음을 입증했다.

Organic fanning in the UK has been greatly grown for the last decade. Two policies for supporting organic farming introduced in 1994 and 1999 played a crucial role in expanding organic farming area and increase in the number of farmers taken up organic fanning methods. Comparing the two policies, this paper identifies that the significant increase in financial aid to organic fanning in 1999 not only was a key factor to succeed in the scheme but also provided environmental base for further development of rural areas. However, such a national aid scheme should be improved in order to reflect regional specific characteristics in terms of environmental protection and local social and economic development. the experience of the UK suggests that the role of organic fanning in rural economics should be defined before enhancing financial support to farmers.

Offshore-aquaculture is a new idea, has emerged as an alternative method, which can minimize the damage to the natural disaster due to the environment pollution by the fish farming activities in the coast and overcome the problems of vicious cycle in fish farming management. On the other hand, as the current fish farming laws and institutions focus on the support for offshore-aquaculture, having the limit to revitalizing and supporting the fish farming business in the open sea, it is necessary to amend the laws and institutions related to fish farm. We should be establish in connection with offshore-aquaculture, after the study aims at examining the foreign laws and institutions in such countries as USA and Norway, establishing the methods for the future laws and institutions of open sea fish farm through the analysis of the issues and controversies in the process of enactment in Korea.

The agriculture in Korea has been gradually changed from a labor-intensive type to a labor-saving one which aims to maximize productivity of labor. Herbicides have been utilized in rice farming since 1955. The consumption of herbicides rapidly increased during the last decade. However, the technology of weed control with herbicides has not been developed yet. For the dissemination of efficient weed control methods in farming, both research and extension activities on herbicide utilization should be strengthened. Appropriate research and guidance units on weed control should be established as early as possible, in order to provide the necessary technical information.

The status of recently expanded exotic pangasiid catfish Pangasius hypophthalmus, Pangasiidae farming in rural Bangladesh has been studied for finding research needs, through knowing the culture methods, associated activities and problems, to make the farming sustainable. Data were collected using participatory rural appraisal (PRA) tools in nine villages in three upazilas (sub-district) of Mymensingh district. The farmers have not got any formal training and have developed their knowledge on farming the fish through practice over years and sharing of knowledge among fellow farmers. Linked industries, e.g. hatcheries, nurseries, feed mills, trading of feed and fish etc. have developed that created employment opportunities. Most of the farmers produce two crops a year. About 90% of the farmers were found to practice mono culture of pangasiid catfish at high stocking density. The feeding rates started from 10-15% of the body weight per day at fingerling stage that reduced to 4-6% with growth. The average yield was found to be 25 tonslha/year. The livelihood of the farmers has been improved through farming the fish. Women and children were rarely engaged in the activities. The identified major problems in farming the fish were water quality deterioration, high feed costs and declining consumer demand and market price.
