  • 최근 유기농법이 확산되며 벼농사와 더불어 맛과 영양소 측면에서 월등하게 높은 가치를 평가받는 미꾸리를 활용한 생태농법이 농업과 어업이 결합된 차세대 산업으로 급부상하고 있는 추세이다. 본 연구는 복합생태농업이 식생다양성 기능에 미치는 영향을 알아보기 위해 수행하였다. 연구방법은 식생조사를 통한 식물학적 분류를 통해 분석하였다. 전체 연구대상지에서 식생조사 결과 38과 100속 107종 20변종 127종류가 출현하였다. 둠벙이 있는 복합생태논에서는 출현하였으나 둠벙이 없는 대조논에서 출현하지 않은 종은 총 15종류(Taxa)의 차이로 확인되어 둠벙의 유무에 따라 식생의 수분요구도 차이로 나타난 결과로 판단된다. 또한 생활형 분석결과 둠벙의 유무에 따라 접지, 일년생, 수생식물의 차이도 확인되었다. 출현한 귀화식물도 전국적으로 널리 분포하는 종으로 분석되었다. 습지출현빈도 분석결과 둠벙이 있는 복합생태논이 대조논에 비해 절대습지식물과 임의습지식물의 비율이 높게 나타났다. 본 연구결과 생육환경이 다양할수록 식생다양성은 높아질 것으로 판단된다. 하지만 유형별 통계적 유의성은 확인되지 않아 식생다양성 및 생물다양성 증진을 위해서 향후 둠벙의 유무, 면적, 둠벙의 깊이, 수문, 수질환경, 토양환경 등 다양한 환경적 요인 찾는 추가적인 연구가 필요하다고 판단된다.

  • The study was conducted to indentify systematically current marketing structure and markeiing efficiency of major cash crops such as red peppers and garlics. That various data and information have been used to analyze the problems related, some of them have come from secondary sources, but major parts of real circum stances were primarily obtained from the scheduled field survey. Some of valuable facts and consequences stemmed from the research can be summarized as fellows: First of all, the commercial rates of peppers and garlics produced by sample farms were 87.5 percent and 69 percent, respectively. On the other hand, annual handling volumes per marketing firm of those two crops were on the average estimated into 51,000 kyun(about 600gr) for peppers and 20,000 hundred bulbs of garlic. As seen physical losses over the entire marketing channels of each crop, it was approximately calculated in 14.7 percent of peppers and 21.1 percent of garlic, respectively. Secondarily, it was found that marketing chanells of these crops are very diversified and complex. However, the five-staged chanell is typical: i.e., from producers to local consigners, to local carry-out merchants, to consigner-wholesales, and finally to retailers. Thirdly, it was also estimated that gross marketing margin, marketing cost and profit based on average grade of peppers were 56.1 percent, 22.6 and 33.5 percent, respectively, having 43.8 percent of farmer's share, and those of garlic 38.9, 17.1, 21.8 and 61.1 percent, separately. To the end, it seems that current collective bargaining power of farmers' cooperatives is virtually weak compared to free individual marketing firms in terms of bssiness volumes and quantity handled over the year.

  • Rodents are well-known reservoirs and vectors of many emerging and re-emerging infectious diseases, but little is known about their role in zoonotic disease transmission in Bhutan. In this study, a cross-sectional investigation of zoonotic disease pathogens in rodents was performed in Chukha district, Bhutan, where a high incidence of scrub typhus and cases of acute undifferentiated febrile illness had been reported in people during the preceding 4-6 months. Twelve rodents were trapped alive using wire-mesh traps. Following euthanasia, liver and kidney tissues were removed and tested using PCR for Orientia tsutsugamushi and other bacterial and rickettsial pathogens causing bartonellosis, borreliosis, human monocytic ehrlichiosis, human granulocytic anaplasmosis, leptospirosis, and rickettsiosis. A phylogenetic analysis was performed on all rodent species captured and pathogens detected. Four out of the 12 rodents (33.3%) tested positive by PCR for zoonotic pathogens. Anaplasma phagocytophilum, Bartonella grahamii, and B. queenslandensis were identified for the first time in Bhutan. Leptospira interrogans was also detected for the first time from rodents in Bhutan. The findings demonstrate the presence of these zoonotic pathogens in rodents in Bhutan, which may pose a risk of disease transmission to humans.

  • The present studies were undertaken to determine accurately whether Korean native fresh-water shrimps can serve as the second intermediate host of Clonorchis sinensis. The experimental results obtained were as follows; 1. Metacercaria of Clonorchis sinensis was not discovered in 36 Macrobranchium nipponensis (De Hann), 1992 Palaemon paucidens (De Hann) and Palaemon madestus Heller, and 860 Caridina leucastica Stimpson, collected in Kimhae district, which were digested in artificial gastric juice, using binocular dissecting microscope. 2. Cercariae of the Chinese liver fluke could not approach the body wall of young shrimps due to streaming caused by their motion. 3. Young Palaemon spp. of 247 were divided into two groups and placed in two different room aquariums, one is at high temperature, the other is normal. Then they were contacted with the cercariae. Only 11 degenerated metacercariae were found in 9 Palaemon spp. It was suggested that they had died immediately or within a few days after penetration. Furthermore the temperature did not affect the infective ratio. 4. At the field experimental aquarium, no metacercaria of Clonorchis sinensis was discovered tn 100 Palaemon spp. which had been brought into contact with 5000 Parafossarulus manchouricus two trials. 5. Specific changes in the cercariae mixed with the extract of shrimps meat were not observed through the dissecting microscope. 6. These results suggest that the Korean native shrimps cannot serve as the intermediate host of Clonorchis sinensis.

  • The most limited production resource in Korea is land. During the period from 1995 to 2002, annual farm land area of 17,600ha have been converted to urban and industrial land. The self-sufficiency rate of rice, Korean staple food, is expected to be decreased from 97.5% in 2003 to 60-70% in 2020. Under such conditions, this study is aimed at first identifying multi-functional benefits of the reclamation projects such as agricultural production, industrial water supply, urban land supply, transportation effects, sightseeing effects and environmental values with and without the projects. To carry out the objectives, three existing tideland reclamation projects such as Daeho, Kumgang and Yongsangang irrigation project stage II were evaluated and Saemangeum tideland reclamation project which was jointly revaluated by environmental NGO and Govn't appointed specialists in 2000 was reviewed. According to this study results, tide land reclamation projects were showed financially and economically feasible and environmentally sustainable. The joint cost like estuary dam should be allocated based on the multi-functional benefits of the projects. To allocate the joint cost, legal and institutional improvement should adapt the joint cost allocation method as the specific cost-remaining benefit method. Korea has more than 402,000 ha of tidal flat of which 76,396ha have been reclaimed in 2003. To meet food security and to cope with shortage of land, phil-environmental reclamation projects should be continuously implemented and necessary tidal flats for protecting environmental ecosystem should be remained according to the detail survey results of reclaimable resources.
