Rice bacterial leaf blight (BLB) by Xanthomonas oryzae pv. oryzae (Xoo) is considered to be one of the major rice diseases steadily occurring around the rice-producing countries. In this study, we developed a recombinase polymerase amplification (RPA) assay for the rapid, convenient and specific diagnosis of Xoo by targeting Xoo-specific transposase A gene. As the target gene can be amplified in 10 min without DNA extraction process and special equipment for temperature control, RPA for BLB can be useful and practical component for on-site diagnosis.

Recently it has been encouraged in developed countries that labor force participation of the elderly is one of the means to cut down the cost of social welfare for them. However, empirical studies have rarely explored how work in later life contributes to national economy. Especially, even though 56.6 percent of elderly workers aged 65 and older engaged in agriculture and forestry in Korea, their contribution has been socio-economically overlooked. This study aims at examining the effect of farming labor in later life on social welfare expenditure. For this purpose, social welfare expenditure was defined as social benefits provided for the elderly by the social security in public sector and measured as transportation allowance, pension, livelihood aid, medical aid, and health insurance in 2003. Data were obtained from National Health Insurance Cooperation and 37 town/village offices and analyzed by 3 age groups; 65~74, 75~84, and 85 and over using SPSS/PC windows program. Results showed that both livelihood and medical support in all age groups were expended more to non-farm than to farm workers. The amount differences per person between them were 113,959~361,132 won in livelihood support and 15,644~51,418 won in medical support. Also, participation in farming influence reduction of livelihood expenditure for the group 65~74 and 75~84 and that of medical expenditure only for the group 65~74. Based on these results, it was estimated the amount of social welfare expenditure reduced by farming labor in later life. The limit of this study and the policy implications of the results are discussed.

The purpose of this study is to investigate exchange between companies and rural communities in 1 company - 1 village campaign and assess functions of NACF(National Agricultural Cooperative Federation)'s 'I Farm Love' as intermediary organization. The result shows that Korea companies participated in 1 company - 1 village campaign to understand rural area and revitalize economic condition in rural community. Most of exchange programs are volunteer works and direct dealing of farm products. The functions of NACF was highly assessed as an informant and intermediary. However establishing networks or promoting exchanges between corporation and rural village were low assessed. It is necessary of NACF to make up for advanced mediation and intermediary between rural villages and companies so that 1 company - 1 village campaign become corporate community investment. Moreover functions to develop programs suited characteristic of companies and set up networks of multi-stakeholders are needed.

The Cooperatives Act was enacted. This enabled people to establish easily cooperatives at various fields. A cooperative is an important vehicle for rural community development. Therefore, the enactment of the Cooperatives Act can be a significant chance for rural policy. The Cooperatives Act have made three significant changes. First, cooperatives can start businesses at all the fields except for financial and insurance business. Second, requisites for people to establish cooperatives have been alleviated exceptionaly. Third, the Cooperatives Act introduced a new cooperative organization, social cooperative which aims to serve the socially excluded class. The self-help approach places rural community members at the core of a development process with two goals: to improve the quality of life within the community and to facilitate the community's capacity building. Community cooperatives contribute to accomplish those goals. One of the roles for cooperatives is to provide products and services at competitive prices. Providing a good or service at a competitive price bcomes increasingly important in some rural communities declines. Cooperative development processes have bic impacts on the ablility of community members to increase human asset and social capital. We conducted a survey targeting rural community businesses to grasp inclinations toward establishing cooperatives. The Cooperatives Act has gained low level of recognition. But so many community businesses wanted to establish cooperatives. This means there is a possibility for many community businesses to establish cooperatives without sufficient understanding. We suggested some policy issues for coping with this situation, as followings. First, the governments should provides rural community residents with opportunities to learn about cooperatives. Second, the current legal systems and regulations about business and social service should be reviewed to do away with the possible discrimination between the new cooperatives and the other forms of incoporation. Third, the cooperation of cooperatives should be encouraged and facilitated in rural communities.

The amylose content of starch is a major factor in the texture of cooked cereal grains. Therefore, down-regulation of amylose synthesis is one of the alternative method to improve eating quality of rice. We developed transgenic rice plants designed to suppress granule-bound starch synthase I(GBSSI) gene using RNA interference(RNAi) technology. Transgenic plants with RNAi vector containing the 3'-UTR region of GBSSI showed a lower amylose content in rice endosperm than that of wild-type. The range of amylose content was 5.9~9.0% in the transgenic plants, whereas that of wild-type was 17.7~18.0%. Transgenic rices showed the decrease of short chain and the increase of long chain by analyzing chain length distribution of amylopectin in the endosperm. In the SEM micrographs, we found that compound starch granules in whole grains of the wild-type rice were readily split during fracturing, while the starch granules in RNAi-transgenic lines showed small voluminous, non-angular rounded bodies.

We developed insect-resistant GM rice(Bt transgenic rice) by inserting the mCry1Ac1 a modified gene from the soil bacterium, Bacillus thuringiensis. The Bt transgenic rice expressing the Bttoxin mCry1Ac1 was tested for the effects on survival of Misgurnus anguillicaudatus and Cyprinus carpio, commonly used as a model organism in ecotoxicological studies. M. anguillicaudatus and C. carpio fed 100% ground rice in suspension, using either Bt rice or non-GM counterpart rice(Nakdong). The Bt rice used for the test were confirmed to have the mCry1Ac1 gene expression by the immuno-strip and ELISA analysis. Feeding test showed that no significant differences in cumulative immobility and abnormal response of M. anguillicaudatus and C. carpio fed on between Bt rice and non-GM counterpart rice. The 96hr-LC₅₀ values showed no difference between Bt rice(>1,000mg/L) and non-GM rice(>1,000mg/L). We concluded that there was no significant difference in toxicity for non-target organisms(M. anguillicaudatus and C. carpio) between Bt rice and non-GM counterparts.

This study aims to identify the factors influencing residents' satisfaction for the urban regeneration projects in South Korea. Data were collected from 250 people with self-administrated questionnaires. A factor analysis identified three factors which are positive economic impacts, negative social impact, and positive environment impact. The positive economic impact has the highest variance explained. Results showed that high income and students and unemployed are less like to be satisfied with their community life. And whereas negative social impacts are less likely to have community satisfaction, positive economic impacts are more likely to have community satisfaction. This study suggested that community leaders and policy makers should consider perceived impacts and income when implementing development projects.
