Objective of this paper is to assess the available data on the pesticide uses and regulations in the golf courses, and provide the nationwide systematic management options. Numbers of golf courses in Korea are rapidly increasing from 2000s and reached at 421 sites by the end of 2011. Accordingly pesticide usage has been increased with years in direct proportion to the increasing number of golf courses. Amounts of pesticide applied in 2011 were 118,669 kg as of an active ingredient and were in the orders of fungicides (54.9%) > insecticides (24.4%) > herbicides (13.3%) > growth regulators (0.1%). Average pesticide usages in 2011 were 280.9 kg per golf course and $5.4kg\;ha^{-1}$. Frequencies of the residual pesticide detections in green and turf were higher than those in fairway and soil, respectively. Residue of highly toxic pesticides was not detected in golf courses. Ministry of Environment in 2010 has developed the 'golf course pesticide monitoring and management system' which is the advanced online registry for kind and amount of pesticides applied in each golf course. This system is intended for monitoring of the pesticide uses and residual levels and protecting the environmental pollution from pesticides in the golf course. In 2009, management of pesticides in the golf courses became the task of Ministry of Environment, being merged from many federal agency and ministries. The protocol for the site-specific best management practices, on which to base results from the risk assessment, should be set for pesticides in the golf to minimize the environmental impacts.

This study investigated the operation criteria of specialized complexes for horticultural production reflecting the farmers' preferences. First, the analysis of the communal activity included six factors: the group purchase of consumables for common activity, group purchase of the greenhouse apparatus, cooperative seed raising, use of a common air conditioning and heating system, cooperative shipping, and soil examination and certification system. The results of the Importance-Performance analysis can be summarized as follows. The factors requiring good management included the group purchase of consumables for common activity, group purchase of the greenhouse apparatus, and cooperative shipping. The factors with a lower priority included cooperative seed raising and the use of a common air conditioning and heating system. While the importance of the soil examination and certification system was low, the satisfaction was high, so this factor needs to be managed to avoid overkill. Second, the analysis of information exchange and education included six factors: production technique information, greenhouse facility management information, distribution-related information, production technique education, greenhouse facility management education, and distribution-related education. The results of the Importance-Performance analysis can be summarized as follows. The factor of production technique education was the most important determinant, plus the factors requiring good management included production technique information, greenhouse facility management information, and distribution-related information. The factors with a lower priority included greenhouse facility management education and distribution-related education. Therefore, to enhance productivity through facility modernization, the scaling up and creation of more specialized horticulture complexes are recommended as policy measures to gain export competitiveness. As the Korean government is expected to expand the scale of specialized horticulture complexes, the results of this paper can be widely utilized.

The functional change of university forest have led to need more complicated techniques for forest management strategies, and more information about forest and natural environment. Therefore the systematic tools, like the so-called Forest Information System to which apply the techniques of geographic information system, are eagerly required for collecting, editing, managing, analyzing the various data about forest and environment, and for supporting the decision-making process. The digital mapping, which could be a primary step to construct the Forest Information System, was carried out using the many kinds of thematic spatial data referring to the Seongju Experimental Forest of Taegu University. As a result, various digital maps including forest type, soil type and so on were constructed. And then we made an user-interface system to link the attributive data in management plan to the thematic spatial data. This system was regarded as the effective tool capable of the more rapid query, analysis and update of related data for systematic management of university forest. Moreover, it would be a useful tool of decision-making in devising, assessing and operating the plan of forest management and development. But there would be much room for supplementation and improvement to make the more convenient and powerful system for the external demands, therefore more concerns and efforts in collecting, revising and updating the data is continuously required.

The objective of this study was to determine microbiological risk factors in hot pepper farms for the application of good agricultural practices (GAP). Samples were collected from cultivation environments and utensils, plants, workers, and air at 3 hot pepper farms located in Cheongsong, Korea and were tested to detect sanitary indications [aerobic plate bacteria (APC), coliform, and Escherichia coli], foodborne pathogens, and fungi. APC, coliform, and fungi were detected at the levels of 0.7~6.2, 0.2~4.7, and 0.4~4.3 log CFU, respectively, in the three farms. Four (4.4%; l leaf, l irrigation water, and 2 soil) of 90 samples collected were revealed to be E. coli positives. For foodborne pathogens, Staphylococcus aureus was only detected at $1.0log\;CFU/100cm^2$ in the worker's cloth of B farm, and Bacillus cereus was detected at the levels 1.0~2.5 log CFU in the cultivation environments and utensils and worker of B and C farms. However, other pathogens were not detected. The results demonstrated potential microbiological risks for hot pepper cultivated in the farms. Therefore, a management system to minimize the microbial risk such as GAP is required to ensure the safety of hot pepper.

본 연구는 방글라데시의 친환경농업 실태와 농업인들의 인식을 바탕으로 친환경농업 개발에 대한 정부의 역할과 정책적 대안을 모색하고자 하였다. 연구 자료는 방글라데시 탕가일 지역의 농업인을 대상으로 유기농가 100가구와 일반농가 100가구를 무작위로 추출하여 설문조사를 통하여 수집되었다. 인구 과밀의 방글라데시 정부는 식량안보를 위하여 지력 저하 및 환경악화를 방지하고자 많은 노력을 기울이고 있다. 즉 지속 가능한 농업개발을 위하여 통합해충관리(IPM), 통합작물 관리(ICM)를 비롯하여 토양의 비옥도 개선, 페로몬트랩이나 자연 천적을 이용한 해충방제 등 다양한 프로그램을 운영하고 있다. 농업인들의 의견 조사에 따르면 친환경농업에 대한 정부의 역할은 긍정적으로 평가하고 있으나 정책이나 관련 프로그램은 아직 부족한 것으로 나타났다. 일반농가인 경우 극히 소수 농가만이 친환경농업을 실행하고 있는데, 이는 관련기술에 대한 지식의 부족과 유기농 비료 등의 자재 부족이 친환경농업을 실행하는데 가장 큰 어려움이라 지적하고 있다. 일반농가의 39%는 유기농업 의사를 보이고 있지만 마케팅시설의 부족과 농사 실패에 대한 두려움 등을 유기농으로 전환하지 못하는 주요 이유로 들고 있다. 일반농가의 일부(17%)만이 정부의 농업교육 프로그램임인 통합해충관리(IPM)과정을 이수하고 있다. 정부의 유기농 정책은 거의 전무하며 NGO들의 지원에 의하여 꾸준하게 진행되고 있을 뿐이다. 따라서 농업인들은 통합해충관리(IPM), 유기농 퇴비, 페로몬트랩이나 자연 천적 등 매우 다양한 농민교육프로그램들을 정부 주도적으로 실시하여야 하며 친환경농업정책을 보다 명확하게 규정하기를 요구하고 있다. 비교적 젊고 교육수준이 높은 소규모 농업인들이 유기농에 적극적임을 알 수 있다. 유기농의 평균 농지규모는 0.246ha, 유기농 평균 경력은 7.63년, 일반농가대비 농가수입은 11.4% 높게 나타났고 비교적 소농들이 높은 수익률을 보이고 있다. 소비자의 신뢰, 마케팅시설, 생산자단체나 조직의 부족 등이 유기농가들의 가장 큰 애로점이 되고 있고, 유기농산품의 표준화를 위하여 정부의 인증제도와 인증기관 설립이 필요함을 지적하고 있다. 유기농을 보다 활성화하기 위해서는 정부 주도하에 마케팅을 비롯하여 교육, 수출 및 각종 장려책 등이 마련되어야 할 것이다.

The prevalence and distribution of hazardous microorganisms were investigated from the major perilla cultivation area at Milyang, Gyeongnam province, Korea. Aerobic plate count (APC) and coliform count of perilla leaves were 4.82 log CFU/g and 3.85 log CFU/g, respectively. E. coli, S. aureus and B. cereus were detected in 3.0% (4/114), 7.9% (9/114) and 46.5% (53/114) of examined perilla leaves. However, E. coli O157:H7, Salmonella spp, and L. monocytogenes were not detected. The distribution of hazardous microorganisms in perilla leaf cultivation environment were compared and the concentration of APC and coliform counts were more than 3.0 log CFU/(mL, g, $100cm^2$, hand) from most of the samples. S. aureus were detected from irrigation water, packing table, packing vinyl, hand, and clothes. Also, B. cereus was frequently detected from the examined samples. Especially, packing table and collection container were contaminated with maximum 5.5 log $CFU/100cm^2$ of B. cereus. Good Agricultural Practice (GAP) system should be introduced to farms to enhance the safety of perilla leaves.
