Among 2,373 slaughtered pigs examined for one year(March 1995 to February 1996), 1,899 pigs had visible pulmonary lesions. Prevalence rate of pulmonary lesion was examined by pathological techniques according to rearing and health managements of pig farms. The results were as follows : 1. Prevalence rate of pulmonary lesion in all-in/all-out flow farms(71.9%) was lower than that in continous flow farms(85.2%). 2. Prevalence rate of pulmonary lesion in non-infected farms with Aujeszky's disease virus and/or porcine reproductive and respiratory syndrome virus(74.4%) was lower than that in infected farms(85.5%). 3. During winter, prevalence rate of pulmonary lesion in farms with cold-control facilities(83.2%) was lower than that in farms with poor cold-control facilities.

The persistence of porcine epidemic diarrhea virus(PEDV) infection was demonstrated in 7 swine farms employing continuous pig flow management even after seasonal outbreaks. Clinically, sporadic postweaning diarrhea was a major concern in those farms. Subsequently circulatory antibody detection using serum neutralizing test made useful for confirmation of PEDV persistent infections. The persistence of PEDV in the premise might have induced recurrence over the period of time.

The "leading farms" or "superior management farms" were relatively capable to overcome various limitations in rapidly changing agricultural environment and economic conditions, and quick to adopt agricultural management innovations and accomplish more compared to the other farms in shorter durations. The farmers from these "leading farms" were innovative and dynamic, and endowed with potentials to be the core leaders in rural society. Their adaptability created a difference and worthy of emulations. The purpose of this research was to propose a policy to develop, promote and sustain these leading farms. There were some problems in communication structures and in implementing agricultural policies for upbringing leading farmers. In coordination with the Ministry of Agriculture and Forestry(MAF) and Rural Development Administration (RDA), this article attempted to come up with workable strategies to solve these problems affecting the leading farms.

The aims of this study were to classify the cultivation status of medicinal crop farmers and to obtain basic data on domestic medicinal crops. To this end, 406 medicinal crop farmers participating in farming education programs in 14 cities and counties were surveyed over 10 months. The results were as follows. First, the biggest difficulty farmers faced in the overall production of medicinal crops was a lack of cultivation skills. Second, in a detailed inquiry about each difficulty item, the most difficult problems were injury by continuous cropping of root-using crops, shortage of specific farm machinery, uncertain market prices, and lack of knowledge about pest control or the positive list system (PLS). Third, the profitability of medicinal crops increased with career experience. Among the farmers who earned profits, requests for education and technical guidance were the most important factors for profitability. Fourth, the results of the analysis suggest that to achieve stable cultivation of medicinal crops, the following items need to be addressed: development and supply of basic cultivation technologies, climate response, registration of pest control pesticides, a solution to the injury by continuous cropping, and contracting cultivation expansion. Additionally, to improve profitability, it is necessary to create conditions that enable the same crops to grow for a long time in one region.

The goal of this study is to determine, based on survey results, the underlying factors that affect the intention of the farmers who have not adopted the Hazard Analysis and Critical Control Points (HACCP) system for the rearing phase of pig production to adopt this system in the future. The research model for this study was con structed based on strategic contingency theory, the theory of the diffusion of innovation, and the technology acceptance model (TAM). Using structural equation modeling with partial least squares (PLS), this study analyzes the effects of the intensity of competition, the environmental uncertainty, the innovativeness and self-efficacy of the individual farmers, and the impact of the credibility of the Agricultural Technology Service Center (ATSC), which acts as the principal agent of technology dissemination and as a leader of change, on the perceived usefulness of technology and the farmers' intention to adopt the system. The results of the analysis are as follows. First, with regard to the underlying factors affecting the intention to adopt the new system, the intensity of competition within the industry and the institutional credibility of the ATSC were inferred to underlie the perceived usefulness. Second, institutional credibility has a positive impact on the perceived usefulness of the system, and the perceived usefulness, in turn, has a positive impact on the intention to adopt. The perceived ease of use also has a positive impact on the intention to adopt. Because the factor that has the biggest impact on the intention of a farm to adopt is the credibility of the ATSC, it is crucial for extension organizations, such as the ATSC, to make greater efforts to promote the expansion of the HACCP system. Because farmers feel that the implementation of the HACCP system is an instrumental strategy for coping with the high intensity of competition within the industry, they attempt to gain a competitive edge through the production of safe livestock products.
