Current rural development polices in Korea consist of three programs, namely: integrated rural community development, rural tourism development, and community based industry development. Within these areas, national and local policies have often concentrated on trying to encourage ‘bottom-up’ development revolving around the commodification of cultural or amenity resources. In important ways, the three categories of rural development programs are more of a community development program than an economic development program. In Korea, it is true to say that governmental decisionmaking is slowly being influenced in terms of community, self-reliance and self-help, which are gradually creeping into the discussion on rural development. I suggest that the planning process itself had to include broad public participation and partnership and bottom-up approaches, not merely the product of a planning office or consulting firm.

Granulocyte colony-stimulating factor (G-CSF) is a cytokine secreted by stromal cells and plays a role in the differentiation of bone marrow stem cells and proliferation of neutrophils. Therefore, G-CSF is widely used to reduce the risk of serious infection in immunocompromised patients; however, its use in such patients is limited because of its non-persistent biological activity. We created an N-linked glycosylated form of this cytokine, hG-CSF (Phe140Asn), to assess its biological activity in the promyelocyte cell line HL60. Enhanced biological effects were identified by analyzing the JAK2/STAT3/survivin pathway in HL60 cells. In addition, mutant hG-CSF (Phe140Asn) was observed to have enhanced chemoattractant effects and improved differentiation efficiency in HL60 cells. These results suggest that the addition of N-linked glycosylation was successful in improving the biological activity of hG-CSF. Furthermore, the mutated product appears to be a feasible therapy for patients with neutropenia.

A common post-harvest disease of sweetpotato tuber is root rot caused by Fusarium solani in Korea as well as the other countries. Storage root rot disease was monitored earlier on sweetpotato (Ipomoea batatas) in storehouses of different locations in Korea. In the present study, an isolate SPL16124 was choosen and collected from Sweetpotato Research Lab., Bioenergy Crop Research Institute, NICS, Muan, Korea, and confirmed the identification as Fusarium solani by conidial and molecular phylogenetic analysis (internal transcribed spacer ITS and translation elongation factor EF 1-α gene sequences). The isolate was cultured on potato dextrose agar, and conidiation was induced. The fungus was screened for Fusarium root rot on tuber of 14 different varieties. Among the tested variety, Yenjami, Singeonmi, Daeyumi, and Sinjami showed resistant to root rot disease. Additionally, the pathogen was tested for pathogenicity on stalks of these varieties. No symptom was observed on the stalk, and it was confirmed that the disease is tissue specific.

Extracellular superoxide dismutase (EC-SOD) is a metallo-protein and functions as an antioxidant enzyme. In this study, we used lentiviral vectors to generate transgenic chickens that express the human EC-SOD gene. The recombinant lentiviruses were injected into the subgerminal cavity of freshly laid eggs. Subsequently, the embryos were incubated to hatch using phases II and III of the surrogate shell ex vivo culture system. Of 158 injected embryos, 16 chicks (G0) hatched and were screened for the hEC-SOD by PCR. Only 1 chick was identified as a transgenic bird containing the transgene in its germline. This founder (G0) bird was mated with wild-type hens to produce transgenic progeny, and 2 transgenic chicks (G1) were produced. In the generated transgenic hens (G2), the hEC-SOD protein was expressed in the egg white and showed antioxidant activity. These results highlight the potential of the chicken for production of biologically active proteins in egg white.

This study is a case study focusing on the residents' participation and satisfaction in the promotion of rural development projects under the Block Grants System in Buyeo. Along with changes in the way to support rural development projects, it requires the autonomy, responsibility, creative planning etc. in the municipal governments and the active participation of local residents for the effective development in rural areas. The purpose of this study is to suggest some policy implications by analyzing the relationship between the level of participation of local residents and residents' satisfaction in rural development projects. This study explained the background and characteristics of rural development projects under the Block Grants System, and also reviewed the theoretical literature on the residents' participation and satisfaction, including the survey of the local residents. For this study, we selected some variables, and then divided into the participating groups such as the resident representatives, the development committee and the local residents. Finally, using statistical method we analyzed the level of participation and satisfaction of the local residents in rural areas.

This research was carried out to provide the basic informations for the study of the occupational socialization process of rural development workers. Until now in a study of rural development workers, the study about the socialization process, which is to study the whole change during the life, has not been sufficient. The occupational socialization process of rural development workers may be considered both a process from life as a pre-rural development workers to life as a rural development worker and a process of retirement or resigination as a rural development worker. The socialization process of rural development workers in general is presumed as the five steps. Each theme word corresponding to the cultural characters in each step is as following. (1) Expectation toward Uncertainty: Step before Life of Employing (2) Extra-Passion and Trial and Error: Step for Adapting the Working Life (3) Swimming: Step of Dissension and Desperation (4) Sinking or Avoiding Dissension: Step of Stability and Stagnation (5) Emptying a Lonely Mind: Step of Professional Inactivity and Retirement The five steps appear mixedly and irregularly. At each step, rural development workers can feel the sense of fruitage and dignity (a naive compensatory mind) despite appearance intermittent and unclear.

This study intends to review the sustainable agriculture and rural development concepts and practices and to present their directions toward better rural planning. Review of related literature including use of available documents and field visits both in Korea and overseas countries are two main methods of data collection with no quantitative analysis. Before sustainable (rural) development was fashionably used in the 1990s in the world, sustainable agriculture and other similar terminologies such as organic farming, alternative agriculture, low-input sustainable agriculture, natural farming, and environment-friendly farming are considered important in the academics as well as In action. The significant relationship between farmers' engagement in sustainable farming and their participation in voluntary social organizations is evidenced, so that it might be said that sustainable agriculture be the basis of sustainable rural development. Whether in sustainable agriculture or in sustainable rural development, the sustainable rural economy is considered more important toward better rural planning both in Korea and in the world.
