Based on RBV(Resource Based View), IT of SMEs classified into IT resource and capabilities. And We confirmed that capabilities and resources affected each performance. In other words, based on the questionnaire of SMEs and IT professionals, divides capability from the overall IT resource that are possessed by SMEs. Among the four attributes (value, rare, non-substitutability, imperfect imitability) presented by Barney (1991), this study targeted at value and imperfect imitability and investigated how SMEs recognize IT resource and capability. Furthermore, this study tests how IT resource and capability influence corporate performance. The result of this study finds that resources that are needed on "Knowledge-based" are classified into IT capability, otherwise classified into IT resource. Analysis shows that server, DB(database), system administrators, programmers, CIO, BA were capabilities, Desktop PC, PC software, software for salary and accounting management, e-commerce, Homepage, and network inside th enterprise were resources. Secondly, this study reveals that both IT resource and IT capability affected company performance (employee satisfaction, CEO satisfaction). IT is certainly having an impact on corporate performance. In conclusion, resource can be either IT resource or IT capability based on they way of utilization. And both IT resource and IT capability have an influence on corporate performance (employee job satisfaction, CEO satisfaction). Therefore, when considering IT investment, a company can purchase necessary IT resource and actively utilize it to be IT capability, which can have an influence on corporate performance in return.

IT outsourcing (ITO) is an integration of two firms-external vendor(s) and a client firm-IT resources by contract. According to resource-based view(RBV), three different resources-ITO vendor's resource, client firm's resource, and the relationship resource between two firms- may have an impact on ITO performance. However, there have been few previous studies considering all three IT resources simultaneously. There have been also few empirical studies in ITO context, which test Bharadwaj (2000)'s findings: 1) IT resources can be divided into tangible IT asset and intangible IT capability, and 2) only IT capability has an impact on the IT performance. Therefore we examined whether, in ITO context, all three different resources have a significant impact on ITO performance. Adopting the findings of previous IT studies, we also divided IT resource into IT asset and IT capability. To achieve this research objective, we analyzed 62 ITO cases of 45 companies being listed in Korean top 100 companies for recent 3 years. Also, we analyzed the data with the Partial Least Squares method. The results of this research lead to the following conclusions: First, only when partnership is high, ITO vendors' resource can have an influence on ITO performance. Second, only client firm's IT capability, not IT asset, is directly related to the ITO success. Third, a firm's IT capability can increase the partnership. Therefore, we concluded that 1) RBV is also an useful theory in ITO context, 2) Bharadwaj(2000)'s suggestion is valid in ITO context as well, and 3) the relationship resource is also important in ITO.

Sesame (Sesamum indicum L.) is an ancient oilseed crop, which is usually cultivated for its seeds. Sesame breeding aims to achieve high seed yield and quality, along with resistance to biotic or abiotic stresses. It is estimated that sesame is originated from Asia or Africa continent. In this study, we characterized 10 agronomic traits and evaluated lignan contents in 165 sesame germplasm originated from Asia or Africa, to select high-yield or high-lignan content accessions. Sesame germplasm showed diverse phenotypes and highly variable lignan contents (sesamin: 0.5-12.6 mg/g, sesamolin: 0.1-3.5 mg/g, lignan: 1.1-16.1 mg/g). Based on originated continent, there are significant difference in agronomic traits, but no in lignan content. Correlation analysis revealed that yield-related agronomic traits were negatively related with lignan contents. Also, PCA analysis showed that most agronomic traits and lignan contents were principal components explaining diversity of whole sesame germplasm. Sesame germplasm was clustered into three groups based on agronomic traits and lignan contents. Finally, we selected high-yield (IT29416, IT167042, K276848, K276849) and high-lignan candidate accessions (IT169254, IT170031, IT169250, IT154876, IT170034), respectively. These accessions are expected to be valuable resources for breeding of high-yield and high-lignan contents functional cultivars.

This study reviews the current status of the Korean landscape resources survey and foreign cases in order to determine the meaning and importance of it. Several cases are compared based on the evaluation method, the evaluation criteria and the application plan. Twelve domestic cases of landscape resources survey are reviewed to understand the current status and limitations of the Korean status, and 5 foreign cases to determine the implications for the Korean system. As the result of the analysis, some implications are drawn for domestic landscape resource system. First of all, it is suggested to establish more objective criteria to evaluate and select landscape resources. Various values of landscape resources should be included into the criteria and more people, as well as experts, should participate to reflect local conditions. Secondly, the management for the landscape resources must be implemented continuously. It is important to introduce a periodic reassessment system and to construct and manage a database of the landscape resources. Lastly, the landscape resource system should be integrated into other programs such as an environmental impact assessment and landscape planning. For a better landscape resource management system and efficient evaluation, resources should be comprehensively managed including various landscape types. It is essential to establish supporting policies and legislation. This research covered only the current status of the landscape resource survey and reviewed a limited number of foreign cases. Despite these limitations, it is meaningful for showing the importance of landscape resource management and to suggest some future tasks for better landscape resources management.

In this study, physical property evaluation and physical separation of the target product were performed to investigate the possibility of using sewage sludge gasification solid residue (GSRs) as a circulating resource. Firstly, the GSRs used in this study was supplied by Sudokwon Landfill Management Corporation, and generally the GSRs was in the form of porous pellets with a particle size of several millimetres. In addition, the partially black areas were confirmed to be unburned and ungasified carbon, and the average carbon content was 5%. In addition, the content of silica, alumina and phosphorus oxide was more than 70% of the total content. It was confirmed that the metallic components of the wet grinding product were separated into individual elements. As a physical separation of metallic and non-metallic components was required, it was finally found that flotation screening was suitable. Accordingly, cationic and anionic surfactants were selected to separate metallic components in which a relatively large amount of non-metallic components were concentrated, and the separation characteristics were confirmed. As a result, it is expected that the concentration of non-metallic components such as silica, alumina and phosphorus will be easier than the separation of metallic components. Therefore, since it is possible to physically treat the gasified sludge residue, it is judged to have potential as a circular resource according to the proposed recycling method for the separated product.
