There are many attempts to develop rural areas by the use of local resources. Local industrialization is a well-known means to found industrialization by the local people using specialized local resources. However, there are many difficulties local people face in the industrialization of these local resources. This is mainly due to local people's lack of experience and knowledge in the development of these resources and the foundation of industrialization in these rural areas require further assistant. This thesis intends to examine the local conditions in order to represent the possibilities and limitations of the industrialization in the use of local resources, Gokseong cotton. We will further suggest various methods & means of these applications and illustrate the efficient approach to development scheme.

This study aims to analyze the affecting factors-construction of collaborative planning process and effect on Comprehensive Rural Village Development Project. To this end, targeting the 36 districts which were selected for 2004 Comprehensive Rural Village Development Project and completed their 2010 5-year projects, components of collaborative planning process and planning effect will be drawn and the affecting factors-construction of collaborative planning and effect on Comprehensive Rural Village Development Project will be analyzed below. According to the results of this study, the affecting factors of collaborative planning process of Comprehensive Rural Village Development Project on planning effect, The level of effect of individual component on endogenous variable appeared greatest mostly in the upper groups. In terms of the level of individual component effect, social learning process and interaction among participants affected greatest. The process of Comprehensive Rural Village Development Project is evaluated that it reflected collaborative planning theory of Healey enough. Therefore, in the course of Comprehensive Rural Village Development Project progress, collaborative planning model must pass social learning process and interaction among participants which are the most important components out of collaborative planning process as we saw in the upper groups. And in order to maximize the performance and results of Comprehensive Rural Village Development Project, the following sequential affecting factors model as Figure 7 must be suggested as optimal collaborative planning models of Comprehensive Rural Village Development Project. Based on the results of the study, the policy implication was drawn as follows. First, systematic supplementations in the form of a consultative body are required to perform Comprehensive Rural Village Development Project efficiently. Second, network needs to be built among different participants in Comprehensive Rural Village Development Project process. Third, systematic mechanism is required to improve social learning among different participants. Fourth, systematic rearrangement is required to guarantee the residents' realistic participation in the course of Comprehensive Rural Village Development Project process.

This study attempted to propose a space planning of rural villages having been connected by small-regions units as a plan of regional economic growth through cultivating native resources located in rural areas and then developing them. As research methods, this study carried out literature research and empirical study at the same time, and then was progressed to directions of deducing a basic plan by applying alternatives to actual object sites based on the results. Endogenous developments of areas through native resources' developments have been emphasized in Korea recently, and various policies and strategies are being appeared for making regional economic growth under these recognitions. However, rural village planning has directed to physical maintenances centering on functionality till now, and composed of facility repairs and experience projects of urban-rural interchanges mostly so as to solve living environments between cities and agricultural villages. Therefore, this study intended to pose discrimination with existing rural village planning, and set up a growth plan of rural villages by cultivating and developing tangible and intangible native resources having been kept in the rural villages and then commercializing them centering on indigenous native resources.

The lacquer is one of the most important resources for endogenous development and cultural reproduction in Wonju. However traditional and social network, which had been formed by lacquer farmers, group of lacquer-pickers, refineries, and lacquer-ware craftsmen, is being collapsed. It is due to the recent imports of raw lacquer from China and refined lacquer from Japan. Public sectors including Wonju city have continuously improved the potential of lacquer production by planting lacquers. However, the potential of lacquer production isn't under enough condition to realize its value. In this study, it is suggested that the efforts of public sectors to raise lacquer industry, focused on the improvements of lacquer production potential until now, should be concentrated on realization of the production potential by reconstructing social productive system which is composed of diverse groups involved in lacquer ware production.

Diabetes mellitus, the most common metabolic disorder, is divided into two types: type 1 and type 2. The essential treatment of type 1 diabetes, caused by immune-mediated destruction of ${\beta}-cells$, is transplantation of the pancreas; however, this treatment is limited by issues such as the lack of donors for islet transplantation and immune rejection. As an alternative approach, stem cell therapy has been used as a new tool. The present study revealed that bone marrowderived mesenchymal stromal cells (BM-MSCs) could be transdifferentiated into pancreatic cells by the insertion of a key gene for embryonic development of the pancreas, the pancreatic and duodenal homeobox factor 1 (PDX1). To avoid immune rejection associated with xenotransplantation and to develop a new cell-based treatment, BM-MSCs from ${\alpha}$-1,3-galactosyltransferase knockout (GalT KO) pigs were used as the source of the cells. Transfection of the EGFP-hPDX1 gene into GalT KO pig-derived BM-MSCs was performed by electroporation. Cells were evaluated for hPDX1 expression by immunofluorescence and RT-PCR. Transdifferentiation into pancreatic cells was confirmed by morphological transformation, immunofluorescence, and endogenous pPDX1 gene expression. At 3~4 weeks after transduction, cell morphology changed from spindle-like shape to round shape, similar to that observed in cuboidal epithelium expressing EGFP. Results of RT-PCR confirmed the expression of both exogenous hPDX1 and endogenous pPDX1. Therefore, GalT KO pig-derived BM-MSCs transdifferentiated into pancreatic cells by transfection of hPDX1. The present results are indicative of the therapeutic potential of PDX1-expressing GalT KO pig-derived BM-MSCs in ${\beta}-cell$ replacement. This potential needs to be explored further by using in vivo studies to confirm these findings.

The objective of this study was to determine the effect of exogenous abscisic acid (ABA) on the red coloration and endogenous ABA contents of apple fruit skins. ABA and fluridone (an ABA synthetic inhibitor, FD) was sprayed on 'Hongro' apple fruit skins at 107 days after full bloom (DAFB). Visual coloration and hunter's color values were not affected by the ABA and FD treatments. Anthocyanin contents in fruit skins increased similarly to hunter $a^*$ values of fruit skins, but ABA and FD did not affect its accumulations. Liquid chromatography analysis revealed that endogenous ABA contents in control fruit increased at first and then decreased from 12 hours after the treatment. ABA treatment increased ABA contents in fruit skins from 2 hour after the treatment and it lasted until the end of the treatments. FD decreased ABA contents in fruit skins from 6 hours after the treatment. ABA treatment increased MdNCED2 (an ABA biosynthetic gene), MdACO1 (an ethylene biosynthetic gene), and MdCHS and MdDFR expressions. However, MdUFGT expressions were not affected by ABA treatment.

Many of biochemical or physiological processes can be regulated by non-coding RNAs as well as coding RNAs in plants, animals and microbes. Recently, many small RNAs including microRNAs (miRNAs) and endogenous small interference RNAs (siRNAs) and long non-coding RNAs have been discovered from ubiquitous organisms including plants. Biotic and abiotic stresses are main causal agents of crop losses all over the world. Much efforts have been performed for understanding the complex mechanism of stress responses. Up to date, many of these researches have been related with the identification and investigation of stress-related proteins, showing limitation to resolve the complex mechanism. Recently, non-coding RNAs as well as coding genes have been gradually interested because of its potential roles in plant stress responses as well as other biophysical aspects. In this review, various potential roles of non-coding RNAs, especially miRNAs and siRNAs, are reviewed in relation with plant biotic and abiotic stresses.

The aim of this paper is to explore the role played by the endogenous farming organization sustaining rural community's competitiveness. Nulmi-Ri, Chungdo Kun in Kyongsangbuk-do chosen as a case study area is known to be one of the most competitive rural communities, making a living with a peach farming. This community maintains its competi- tiveness by operating a community-based filming organization which was organised in an endogenous way. Most of individual farmers in this community belong to the farming organization and they have cooperative relationships in the processes of production and distribution. In this respect, the exchange and circulation of knowledge, and collective learning, tend to be significantly taken place between the organization members. Based on the experience of the Nulmi-Ri's endogenous farming organization, we propose some constructive comments for rural community development.

The Bombyx mori Microarray Database (BmMDB; http://silkworm.swu.edu.cn/microarray) provides information for tissue-specific gene expression by using the whole-genome oligonucleotide microarray in the silkworm. We analyzed the tissue-specific expression patterns in the silk gland, fat body, and midgut five days of fifth instar larvae during the development of B. mori. To verify the tissue-specific expression, analysis was conducted using quantitative Real-time RT-PCR and the highly expressed endogenous Actin RNA as an intrinsic reference. Finally, we confirmed five genes, (sw15872, sw00692, sw20990, sw05300,and sw2250), out of 18 candidates expressed in two different tissues, which was consistent with the data published by Dr. Xiang's group, thereby supporting the BmMDB. Further studies for promoter regions of candidate genes can be applied in creating transgenic silkworms as biomedical insects for use in producing biomaterials, and to serve as well-characterized models for understanding the mechanism for the genetic regulation of tissue-specific development.
