    ABSTRACT: There has been growing concern as to whether the growing investment in rural South Korea is achieving the desired ends. Empirical evidence is required to assess the current policies. Based on the logic of those policies, this study conducts an ex-post evaluation of outcomes following the termination of the Rural Traditional Theme Village program previously operated by the Rural Development Administration, a central government agency in South Korea. The research adopts farm households' non-farm income as an ex-post quantifiable indicator and assesses the impact of the Program on this indicator. It is found that the Program was evaluated positively and as being effective from both cross-sectional and longitudinal perspectives. It is concluded that in the absence of the program the farms would have experienced difficulties in making non-farm income due to the lack of internal competitiveness and the deterioration of human resources.

    ABSTRACT: The objective of the present study was to compare the effect of sow and/or piglet vaccination regimen by three commercial porcine circovirus type 2 (PCV2) vaccines on pigs experimentally challenged with PCV2 at 84 days of age based on immunological, virological, and pathological evaluation. One hundred and nineteen piglets born to vaccinated or non-vaccinated sows were divided into 17 groups. A portion of the pigs with or without passively acquired immunity was vaccinated at 21 or 49 days of age. Regardless of the PCV2 vaccine, the combination of sow and pig (49 days of age) vaccinations significantly (P < 0.05) reduced PCV2 viremia, induced higher log2 transformed neutralizing antibody titers, and resulted in higher proportion of CD4+CD8+IFN-γ+ lymphocyte subsets than the sow vaccination alone, the pig (21 or 49 days of age) vaccination alone, and the combination of sow and pig (21 days of age) vaccinations at various days post challenge. The results showed a significant negative correlation between maternally derived antibodies at the day of vaccination and the increment of antibody titers to PCV2 at 28 days post vaccination in the combination of sow and pig (21 days of age) vaccinations but not the combination of sow and pig (49 days of age) vaccinations. The combination of sow and pig (49 days of age) vaccinations could be more effective for controlling PCV2 infection if PCV2 the infection occurs during the growing-finishing period in herds. Optimal vaccination strategies must balance the advantage of delayed vaccination with the need to induce immunity prior to exposure to pathogens under field conditions.
