  • A stochastic simulation model incorporated with Reed-Frost approach was derived for evaluating diagnostic performance of a test used for a screening program of an infectious disease. The Reed-Frost model was used to characterize the within-herd spread of the disease using a hypothetical example. Specifically, simulation model was aimed to estimate the number infected animals in an infected herd, in which imperfect serologic tests are performed on samples taken from herds and to illustrate better interpreting survey results at herd-level when uncertainty inevitably exists. From a risk analysis point of view, model output could be appropriate in developing economic impact assessment models requiring probabilistic estimates of herd-level performance in susceptible populations. The authors emphasize the importance of knowing the herd-level diagnostic performance, especially in performing emergency surveys in which immediate control measures should be taken following the survey. In this context this model could be used in evaluating efficacy of a survey program and monitoring infection status in the area concerned.

  • The purpose of this study is to investigate priority of cultural-environmental resource using the Analytic Hierarchy Process. Based on survey of expertise, a series of pairwise comparison judgements is performed to evaluate the relative strength or intensity of impact among the elements in the Hierarchy. This Study are applied three kinds of evaluation criteria and 40 kinds of cultural environmental resource. The results of this study are as follows. First, Traditional culture, landscapes, rural community vitality of Agriculture and Rural culture of environmental resources by establishing the concept of a comprehensive classification scheme are defined by the United Nations Food and Agriculture Organization (FAO) and the Rural Amenity Resources Multifunctionality in Agriculture. Second, Experts was considered important to "Continuity of history (43%),"> "Global importance (37%)"> "Notable characteristic (20%)" the order of the ratings on the importance of culture with rural agricultural and environmental resources. This is deemed the most important part of Continuity of history Third, The importance of the cultural and environmental resources comprehensive evaluation of the results, a strong tradition of building traditional sense or a landscape resource most highly were evaluated. and Vinyl greenhouse and warehouse such as agriculture, the current facilities required the relatively compared to other resources very low importance were evaluated. Resources, the importance of this study is judged to be able to be utilized as basic data in the selection criteria for the evaluation of the agricultural heritage.

  • The feasibility of precision farming for small sized fields was studied by determining fertilizing amount of nitrogenous and calcareous to a cite specific region. A detailed soil survey at three experimental fields of 672㎡, 300㎡ and 140㎡ revealed a considerable spatial variation of the pH and organic matter(OM) levels. Soil organic matter was measured using Walkley-Black method and soil pH was measured with a pH sensor. Soil sample was obtained by Grid Node Sampling Method. The soil sampling depth was 10 - 20 cm from the soil surface. To display soil nutrient variation, a soil map was made using Geographic Information System (GIS) software. In soil mapping, soil data between nodes was interpolated using Inverse Distance Weighting (IDW) method. The variation was about 1 - 1.8 in pH value and 1.4 -7 % in OM content. Fertilizing Amount of nitrogenous and calcareous was determined by the fertilizing equation which was proposed by National Institute of Agricultural Science and Technology.(NIAST). The variation of fertilizing amount was about 3 - 11 kg/10a in nitrogenous and 70 - 140 kg/10a in calcareous. The results showed a feasibility of precision fertilizing for small size fields.

  • During a survey of fungal diversity of the order Mucorales, three zygomycete isolates, CNUFC-YR113-1, CNUFC-KNU16-7, and CNUFC-BS1-1 were isolated from freshwater and soil samples in Korea. The strains were analyzed both morphologically and phylogenetically based on internal transcribed spacer and 28S rDNA gene sequences. Based on their morphology and phylogeny, the CNUFC-YR113-1 and CNUFC-KNU16-7 isolates were identified as Actinomucor elegans, and CNUFC-BS1-1 was identified as Mucor minutus. To the best of our knowledge, the species A. elegans and M. minutus, belonging to an undiscovered taxon, have not been previously described in Korea.

  • This paper describes the results of a survey aimed at characterizing smallholder pig production systems in northern Lao PDR. A total of 341 households from five Northern provinces were interviewed in the survey. Village meetings and individual interviews, using a semi-structured questionnaire, were used to collect information. Three main pig rearing systems, free-scavenging, semi-scavenging and confinement (enclosures and pens), were found in the survey areas. These systems were practiced differently by smallholders depending on the level of intensity of crop production, ethnicity and purpose of keeping pigs. The confinement system was mainly practiced by Lao-Tai and Tibeto-Burman groups, who mainly bought piglets and fattened these pigs for sale. In contrast, the Mon-Khmer and Hmong-Mien reared pigs in free-scavenging and semi-scavenging systems, and usually keep sows for piglet production. The main factors that affected the changes in rearing systems were found to be level of intensity of crop production, local regulations and outbreaks of disease. The main constraints found in smallholder systems were outbreaks of disease, high mortality of piglets and the slow growth rate of fattening pigs.

  • 고품질의 차 생산과 풍요로운 생물다양성의 보전으로 환경과 공생하는 보성 차농업 시스템의 가치를 인정받아 2018년 국가중요농업유산으로 지정받았으나 농업인구의 고령화로 농업시스템의 보전과 전승이 위협받고 있는 실정이다. 이에 본 연구에서는 보성 차농업시스템의 보전과 차세대 전승 방안의 하나로 세계중요농업유산시스템의 등재를 제안하고자 한다. 본 연구는 세계중요농업유산과 국가중요농업유산, 보성 차농업 시스템을 검토하고, 2020년 3월에서 5월까지 석 달간 전라남도 보성군 차 재배 농민을 대상으로 방문과 전화 인터뷰를 통한 실태조사와 심층면접조사를 통하여 보성 차 농업인구의 초고령화 실태를 확인하였다. 조사 결과, 보성 차농업인의 평균연령은 69.4세였으며, 2세대 이상 전승 가구는 36%(54명)에 불과하였고, 79.4%(119명)의 농가의 차 수입 의존도가 90% 이상인 것으로 나타났다. 심층면접 결과, 보성 차 재배농업인의 고령화에 대해 우려를 나타냈으며, 세계중요농업유산 등재는 보성 차에 대한 신뢰도와 인지도 향상으로 이어져 보성 차농업시스템의 보전과 전승에 도움이 될 것이라고 응답하였다. 세계중요농업유산 등재는 보성 차 농업시스템의 농업가치를 전 세계와 공유하고 미래에 전승할 수 있다는 점에서 더없이 훌륭한 자산이 될 것이다.

  • 국내산 유통 수삼 중 농약의 잔류특성을 구명하기 위하여 전국 15개 지역의 45개 재래시장 상점에서 45점의 시료를 채취한 후 GC-MS/MS와 LC-MS/MS를 이용한 다성분동시분석법을 이용하여 잔류농약을 분석하였으며, 검출된 농약은 GC-ECD/NPD를 이용한 개별분석으로 수삼 중 잔류농약을 정량하였다. 잔류농약 분석 결과 총 45점의 시료에서 cypermethrin, fenitrothion, fludioxonil, thifluzamide, tolclofos-methyl이 검출되었으며, 검출율은 35.6%이었다. Tolclofos-methyl이 가장 높은 검출빈도를 보였으며, 인삼에 대한 안전사용기준과 잔류허용기준이 설정되어 있지 않은 fenitrothion이 검출되었다. 수삼에서 검출된 농약은 모두 잔류허용기준 미만이었다. 수삼 중 검출된 농약의 일일섭취허용량 대비 일일섭취추정량은 0.03-16.67%이었다.

  • 청주지역에서 유통중인 농산물 중 농약의 잔류실태를 조사하고 안전성을 평가하기 위하여 도매시장과 재래시장에서 총 120점의 농산물을 채취하여 GLC와 HPLC 및 GC-MSD를 이용한 다성분동시분석법으로 분석하였다. Procymidone과 penconazole 및 tetraconazole과 같은 3종의 살균제가 양파, 부추, 토마토, 풋고추에서 검출되었다. 도매시장에서 채취한 양파에서 살균제 penconazole이 검출되었으며, 재래시장의 경우는 살균제 procymidone이 부추와 토마토에서, 살균제 tetraconazole이 풋고추에서 검출되어 3.3%의 검출율을 나타내었다. 검출된 농약의 일일섭취추정량(EDI)은 일일섭취허용량(ADI)의 0.1% 미만으로 안전한 것으로 판단되었다.
