Recently farming succession has become an important topic in agriculture in order to secure agricultural manpower in response to the aging of farming households and declining population. This study investigates farmers and agricultural college students’ perception of farming succession in Korea, especially of farming succession to a third party. Farmers and agricultural college students are potential farming transferors and successors, respectively. We surveyed 146 farmers and 95 students who graduated or were studying at the Korea National College of Agriculture and Fisheries. The questions of the survey are largely divided into four categories: 1) the will and scope of farming transfer and succession, 2) the requirements for the successors of farming, 3) the perception on the succession to third-parties, and 4) the farming succession policy. According to the survey results 41.4% of farmers and 46.3% of potential farming successors have willingness to accept a farming succession to a third party. When farming succession was carried out through the Farming Succession Exchange, 46.8% of farmers and 54.7% of successors said they are willing to carry out third-party farming succession. This means that a third-party farming succession could be activated if the reliability issue that may arise during the farming succession is resolved through the Farming Succession Exchange. Other implications for farming succession are suggested at the end of this study.

The purpose of this study is to explore the dynamic properties of causality and asymmetric price transmission in the distributional channel of the tomato market in Korea. Using the wholesale and retail price series of the tomato market, we obtain the following results. First, the price transmission mechanism reveals the causal relationship channeling from the wholesale price to the retail price. Second, we find an asymmetric price transmission from the analysis using the threshold partial adjustment model. The retail price responds strongly when the wholesale price increases. On the other hand, the retail price shows sluggish adjustment when the wholesale price decreases.

Quality characteristics, such as moisture content, pH, acidity, sugar content, salinity, flavor, taste, color, and overall acceptance of apple Jangachi prepared with different apple cultivars were investigated after different times in storage. The initial moisture content of apple Jangachi was 14.19-16.94% according to cultivar. After 5 days of storage, the moisture content increased to 23.26-26.91%. The pH was 3.98-4.55 regardless of cultivar. Total acidity decreased at first and then increased slightly after 10 days in the range of 0.8% to 1.3%. The sugar content of apple Jangachi decreased from 60-68% to 27-34% on the 5th day and was maintained at 23-25% after 5 days regardless of apple cultivar. The salinity of apple Jangachi increased from 0.94-1.64% to 3.5-3.8% after 15 day regardless of cultivar. In the sensory evaluation, apple Jangachi prepared with the Gala cultivar was given the best ratings in overall acceptability.

본 연구에서는 무농약 산머루 즙의 양을 각각 50 g, 100 g, 150 g, 200 g 수준으로 다르게 첨가하여 양갱을 제조하고 색도, 당도, 기계적 조직감, 관능평가를 조사하였다. 무농약 산머루 양갱의 색도는 명도(L)값과 황색도(b)값이 무농약 산머루 즙의 첨가농도가 증가할수록 감소하였으나, 반대로 적색도(a)값은 증가하는 경향을 나타내었다. 당도는 대조군이 2.31 Brix로 가장 낮게 나타났으며 무농약 산머루 즙의 첨가량이 증가할수록 당도가 점차 높아져 유의적인 차이를 보였다. 기계적 조직감은 무농약 산머루 즙의 첨가량이 증가할수록 경도는 증가하는 경향을 나타냈지만, 탄력성, 응집성, 점착성, 씹힘성 등은 모두 감소하는 경향을 나타내었다. 관능검사 결과는 색, 향, 맛 등의 전체적 선호도에서 무농약 산머루 즙 150 g 첨가군이 가장 높은 점수를 얻었다.

The objective of this study is to analyze the willingness to change into organic blueberry and the activating strategies on domestic products. For the activation of domestic blueberry, it is necessary to get the quality certification, especially organic certificate and develop the technology for increasing production. It is investigated that the smaller product, younger farmer and higher price expected, the higher willingness to change into organic blueberry. The results and finding of this study can be used to build-up the technical and marketing supporting system that reflects the rapid change of customer’s preference on blueberry.
