The present study was conducted to explore which variables form consumer`s risk perception of large-scale livestock diseases and how these variables affect their intention not to buy livestock products. For this purpose, a research model was established and used the results of a survey gathered from 728 adult males and females across the country in a structural equation model for analysis. The results revealed that factors affecting the consumer`s risk perception included the level of news exposure, involvement, and subjective knowledge of the diseases, and that anxiety and intention not to purchase increased as the risk perception rose. In addition, it appeared that risk communication affected the relationship between risk perception and anxiety, while reference groups affected the relationship between anxiety and intention not to purchase. The outcome of this study suggests that, in order to reduce consumer`s risk perception toward the large-scale livestock diseases, it is necessary to expand education for accurate awareness of the risks and respond to the consumers according to their levels of news use and involvement. Furthermore, public institutions need to strengthen risk communication and actively react to food safety information distributed through SNS, so that the risk perception does not increase anxiety and intention not to purchase of the public.

This study analyzed the effects of reducing nutrients by managing pollution sources from cultivated area and livestock area in order to improve the water quality of the Lake Paldang Basin. To predict the effects of reducing nutrients in the Lake Paldang Basin, water pollution sources were first analyzed and possible scenarios to reduce the sources were selected accordingly. Using the basin environmental database, water flow rates, and TN and TP concentrations were simulated based on the Soil and Water Assessment Tool (SWAT) model. Model evaluation indices were calculated through the calibration and validation of water flow rates, and TN and TP concentrations, and they were found that simulation values reflected measurement values well, and that it was possible to evaluate the Lake Paldang Basin both qualitatively and quantitatively. In the case of Scenario 3 in which a measure to reduce pollution sources from both cultivated area and livestock area was applied together, the concentrations of TN and TP were reduced by 29.6% and 28.6% respectively. It is believed to be important to improve water quality by managing pollution sources from both cultivated area and livestock area particularly in area like the Lake Paldang Basin where agricultural and livestock production activities are actively conducted. The results of analyzing the effects of reducing nutrients in the Lake Paldang Basin showed that the concentrations of TN and TP were reduced to 3.42 mg/L and 0.167 mg/L respectively in Scenario 3. It was found that measures to reduce pollution sources from cultivated area and livestock area were effective for improving the water quality of the Lake Paldang Basin. It is also believed that reducing the amount of fertilizer applied to cultivated area is effective for managing nutrients, and that it is necessary to expand environmental infrastructure to reduce pollution sources from livestock area.

본 연구는 축산식품으로부터 식중독균 검출을 위한 시료 전처리법을 확립하기 위해 전처리용액, 균질화 시간, 시료와 전처리용액의 비율에 따른 회수율을 비교하였다. 이를 위하여 햄, 발효유, 소고기에 E. coli O157:H7, S. aureus, S. Typhimurium를 7.0 log CFU/g로 접종하고 PW, SS, BPD, BPW로 처리하였다. 또한 균질화 시간은 30, 60, 90, 120, 300초, 시료와 전처리용액 비율은 1:2, 1:4, 1:9, 1:19로 각각 처리하였다. 그 결과 발효유와 소고기에서는 BPW로 처리하였을 때 전반적으로 식중독균의 회수율이 높았으나(p < 0.05), 햄의 경우에는 전처리 용액에 따른 유의적 차이는 없다. 전처리용액의 최적 비율은 햄, 발효유, 소고기가 각각 1:9, 1:2, 1:4였으며(p < 0.05), 균질화 시간은 모든 시료에서 120초로 처리했을 때 유의적으로 가장 높은 회수율이 나타났다(p < 0.05). 따라서 선정된 최적 전처리 조건에서 식중독균 회수율을 수행한 결과 모든 시료및 균종에서 85%이상의 높은 회수율을 보였다. 이상의 결과를 종합해 볼 때 축산식품으로부터 식중독균 검출을 위한 전처리 용액 및 시료와 전처리용액의 비율은 시료의 종류에 따라 적절한 것으로 사용하는 것이 식중독균 검출의 정확성을 높일 수 있을 것으로 판단되어진다.

This study researched the farming succession conditions and intentions of 607 livestock managers. As a research result, the livestock managers` average age was 59 years and the estimated period of time for continued livestock raising beyond the present time was 10.7 years. The percentage of managers with a farming successor was 41.2%. The percentage of responses claiming that `Management will stop with my generation` was 10.7% of the farms that do not have a farming successor (58.8%). The percentage of responses claiming that they will `Lease or transfer to others` was 18.0% and those claiming `No existing plan` was 30.1%. In regards to identifying prior measures that are necessary for achieving better succession, 25.2% of the respondents answered `Successor`s train or support (Technical education)`. The problems (rated with a 5 point scale) identified during succession processing were `Livestock Regulation` (3.89 points) and `Funding` (3.59 points). The significance of this study was the gathering of basic information on establishing measures to support livestock farming succession. Human training and technical education are needed to maintain continuous succession of family farming.

Objectives: General livestock farmers are known as a high riskgroup for zoonoses, but studies of general livestock farmers in regard tozoonoses have been rare in Korea. We surveyed awareness of zoonoses amonggeneral livestock farmers to suggest directions for education. Methods: A questionnaire was developed examining the workbehaviors and risk factors of general livestock farmers. We conducted a questionnairesurvey on awareness on zoonoses among 265 general livestock farmers. Results: The awareness rates for zoonosis itself,brucellosis, and q-fever were 13.0%, 65.0%, and 2.3%, respectively. The awarenessrate of zoonoses and brucellosis tended to increase with sex. Conclusions: Livestock is the principal reservoir ofzoonoses. Therefore, effective working guidelines for preventing zoonoses amonggeneral livestock farmers must be developed and an educational program onzoonoses is needed for general livestock farmers. Furthermore, publicityactivities on the prevention of zoonoses are needed for high-risk groups.

This study analyzes the livestock industry participant perception of meat auction markets and factors affecting the perception. It was revealed that livestock industry participants generally show positive perceptions about both the necessity and the function of price determination of auction markets. More positive perceptions are detected in Hanwoo market than in Handon market. The generalized ordered logit regression analysis shows that demographic and industry-related factors, such as the type of the participants, the frequencies of using auction markets, the duration of participation, etc, affect these perceptions in Hanwoo and Handon markets differently. For example, both auctioneers and farmers in Hanwoo industry significantly recognize the necessity of auction market, but physical distance from the Eumsung auction market affects the participant perception of auction market in Handon industry. Similar trend is also repeated for the function of price determination of auction markets. The results of the study indicate that improvement plans for auction markets must be differently approached for these markets.

중합효소연쇄반응법을 이용한 축산물 가공식품 내에 존재하는 소고기 성분을 특이적으로 검출할 수 있는 방법을 개발하기 위하여 축산물 가공식품 78종류를 무작위로 선별하였다. 가공식품으로부터 추출한 genomic DNA를 이용하여 소의 미토콘드리아 16S rRNA 염기서열을 이용하여 strain-specific primer를 직접 제작하여 중합효소연쇄반응을 수행한 후, 증폭된 반응산물의 염기서열을 분석 하였다. 축산물 가공식품 내 소고기 성분 검출을 위한 중합효소연쇄반응 수행 결과, 소고기 성분이 함유되어 있는 17개의 축산물 가공식품이 정확히 증폭되었고, 증폭산물의 DNA 염기서열 분석 결과 소의 미토콘드리아 16S rRNA 서열과 95% 이상의 상동성을 보였다. 본 실험에서 제시된 방법으로 축산물 가공식품 내 소고기 성분검출을 적용하였을 시, 소고기 성분이 함유된 축산물 가공식품을 정확하게 감별할 수 있었으며, 나아가 식품 원재료의 허위기재 등에 의한 불량식품 유통 근절 및 종교적 이유로 인한 금기 식품감별 등과 같은 과학적 식품 감시에 기여할 수 있다고 사료된다.

The primary objective of the study is to develop a livestock price index and determine how much the individual index components contribute to the variation of the livestock price index. The livestock price index calculated using a Laspeyres index formula is composed of beef, pork, chicken and egg at the wholesale level, and weighted by the production amount from 2007 to 2009(base period). Results show that the newly developed livestock price index(LPI) in this study has a cointegration relationship, or a long-run equilibrium relationship with the livestock index(LI) that is a subindex of the consumer price index(CPI). Of the components of the livestock price index, pork contributes the most to the fluctuations of the overall index, followed by beef. The average contribution of pork and egg is a negative value respectively, suggesting that they generally contribute to the decrease in livestock price index.
