  • Biomass is considered to be a major potential fuel and renewable resource for the future. In fact, there is high potential to produce the large amount of energy from biomass around the world. In this study, to obtain basic data for practical application of agricultural and forest by-products as fuel of heating system in agriculture, agricultural and forest biomass resources were surveyed, the pelletizer with capacity of $50\;kg{\cdot}h^{-1}$ was designed and manufactured and pellets were made by the pelletizer. High heating value, ash content, etc. of pellets made of agricultural and forest by-products were estimated. Straw of rice was the largest agricultural biomass in 2009 and the total amount of rice straw converted into energy of $299{\times}10^3$ TOE. And in 2009, amount of forest by-product converted into energy of $9,579{\times}10^3$ TOE. High heating values of pellets made of stem and seed of rape, stem of oat, rice straw and rice husk were 16,034, 16,026, 16,089, 15,650, $15,044\;kJ{\cdot}kg^{-1}$ respectively. High heating values of pellets made of agricultural by-products were average 83.6% compared to that of wood pellet. Average bulk density of pellets made of stem and seed of rape, stem of oat, rice straw and rice husk was $1,400\;kg{\cdot}m^{-3}$ ($1.4\;g{\cdot}cm^{-3}$). Ash contents of the pellets were 6.6, 7, 6.2, 5.5, 33% respectively. Rice husk pellet produced the largest ash content compared to other kinds of pellets.

  • 우리나라는 농산물 수출확대를 위하여 농산물 수출지원제도를 운영하고 있으며 수출물류비지원사업도 여기에 포함되어 있다. 수출물류비지원을 통한 수출지원사업을 통해 농산물의 수출확대는 농업부문의 수출산업화는 물론 신수요 창출과 국내 농산물 가격의 안정화에도 기여한다. 우리나라가 DDA 협상에서 개도국지위를 유지하게 되면 WTO 규정이 허용하는 범위 내에서 수출보조의 지속적인 지원이 일정기간까지 가능하나 개도국지위를 상실하게 되면 수출보조금으로 지원하는 수출물류비 등 각종의 지원이 향후 협상에서 결정되는 특정연도에는 완전폐지를 해야 하는 상황이다. 따라서 본 연구에서는 농산물에 대한 수출물류비 지원이 수출에 미치는 효과를 분석하고, WTO/DDA 농업협상 결과 예상되는 수출물류비 감축이나 철폐에 대비하기 위한 농산물 수출물류활동의 활성화 방안과 과제에 대하여 연구해보고자 한다.

  • By using the raw data of the 2015 Agriculture, Forestry and Fishery Consensus that surveyed the farmers engaged in agriculture, forestry and fishery in 2015, this study investigated the effects of the characteristics of the farms in Gangwon-do on the utilization of the digital devices, which was classified into computers usage only, smartphones usage only, both computers and smartphones usage, and no digital device usage. This study used the Multinomial Logit Model for the above purpose. Moreover, the IIA(Independence of Irrelevant Alternatives) method of the Multinomial Logit Model was analyzed to be suitable. Upon the result of the analysis, when all the other variables were constant in the average, the probability of choosing both computers and smartphones increased by 0.02% as the family member living together with the farm owner increased by 1 person. In addition, the farms with agricultural machineries have 0.03% increased probability of using smartphones to sell their agricultural products, when compared with the farms without agricultural machinery. Moreover, for the farms with high sales profit of the agricultural products, the probability of using computers and the probability of using smartphones increased by 0.04% and 0.01%, respectively, and the probability of using both computers and smartphones increased by 0.02%. On the other hand, for the farms affiliated with the agricultural organization, the probability of using both computers and smartphones increased by 0.17%, and the probability of using only smartphones and the probability of using only computers increased by 0.16% and 0.15%, respectively. In case of selling to the National Agricultural Cooperative Federation(NACF), the probability of using smartphones increased by 0.11% if all other variables were to be constant in the average. In particular, the farms participating in the agriculture-related industries have 1.09% increased probability of using computers, have 0.92% increased probability of using smartphones, and 0.85% increased probability of using both computers and smartphones. Therefore, the implications suggested based on the results of the analysis are as follows. First, the farms' choices of the digital devices are made independently. Hence, the future agricultural industry business platform establishment should necessarily consider the types of farms' choices of the digital devices in the future. Second, since the usage of digital devices has a generally positive influence on the farm household income, digital education to improve farmers' ability to use the digital devices should be urgently provided in order to improve the farm household income in the farms in Gangwon-do. Third, because the digital devices used to sell agricultural products differ depending on the age of the farm owner, it would be desirable to target the younger generation of the farm owners rather than establishing the agricultural industry business platform for the farms in the aged farm villages. Fourth, it would be advisable for the future agricultural business platform to consider the characteristics of agricultural products sales source.

  • In 1995, the WTO started to ease the trade barriers. Globalization has accelerated. The opening of the agricultural products market is rapidly gaining momentum with the conclusion of an FTA. The acceleration of this FTA is expected to be a threat to Korea's agriculture, and a new strategy is needed. At the beginning of the nuclear accident, mainly radioactive materials are found in the surface layer of the soil. Over time, the concentration of the plant gradually increases. After 5 years, it becomes noticeable. In March 2016, it will be five years after the nuclear accident. Radioactive contamination is very likely to occur in agricultural products produced in the Fukushima area at this time. In this period, agricultural products produced in the Fukushima region are expected to generate supply disruptions in Japan, and imports to replace them will increase. Therefore, it is necessary to establish a mid- and long-term strategy for exporting to Japan by analyzing the competitiveness of Korean agricultural products. In this study, standardization index was derived by using agricultural price ratio, TSI, export CAC. Based on this, we analyzed the competitiveness of each item in the Japanese market. The analysis shows that garlic is the most competitive product in the Japanese market. Also, strawberry, tomato, and cucumber were found to be competitive. On the other hand, Kiwi, pineapple, soybean, onion, potato, etc. As a result of the analysis, the following strategies were proposed for the export of agricultural products with high competitiveness. First, it is necessary to develop technology to suppress deterioration of export transportation quality. Second, continuous supply of local consumption pattern information is required. Third, it is necessary to expand exports by processing fresh food. Fourth, it suggested the establishment of export base and strengthening of support system.

  • This study was carried out to investigate the consumption behaviors of environmentally-friendly agricultural products, including satisfaction of purchases. Questionnaires completed consumers were statistically analyzed. Regarding purchase frequencies of environmentally-friendly agricultural and animal products, consumers consumed them 1 time per month. No significant differences in consumption by age, living area, family type, or BMI were found. Exactly 38.2% of consumers preferred to purchase items in the packing amount of 0.2-0.5 kg, whereas 39.7% of consumers preferred amounts from 0.5-1.0 kg. Significant differences in packing amount were found according to age (p<0.05) and family type (p<0.01). However, there were no significant differences according to living area or BMI group. Many consumers made decisions based on the outer packing label (69.6%). Significant differences by age and living area were not found, whereas there was significant difference according to family type (p<0.05). Consumers answered that they purchased products in a general supermarket (24.7%) and cooperative (24.2%). Significant differences were found by age and living area (p<0.01) but not by family type. Consumer satisfaction of purchases scored 3.39 out of 5 points. In conclusion, significant differences in consumer satisfaction were not found according to age, living area, family type, or BMI.
