In this study, a new formula of settlement at the head of IGM was suggested and the applicability of suggested formula was verified with field test results. This suggested formula was the function of the settlement at the shaft head and the elastic compression of shaft. The applicability of suggested formula was verified with the result of in-situ load test. Also, the bearing capacity of drilled shaft with the IGM's theory was compared with those of classical theories. The results showed that classical method showed smaller values of bearing capacity than those of field load test data. The results of analysis also showed that the suggested formula and IGM's theory were applicable for the estimation of bearing capacity with the increase of shaft settlement. Especially, settlement correction factor($k_m$), which reflects ground condition and load transfer characteristics, increases as the applying load and shaft deformation increase. This suggested formula was applicable for medium density or higher density of soil condition and $k_m=1$ means yielding load for firm soil condition.

This study was conducted in a glasshouse to examine the possibility of producing tomato plug seedlings in a newly-developed inert phenolic foam medium. Plug seedlings of 'Madison' tomato were grown in four pellet type media, Grodan rockwool, UR rockwool, phenolic foam LC, and phenolic foam LC-lite. Seed germination was checked for 7 days. Seedling growth was measured at 19 days after sowing. The greatest germination was obtained in the phenolic foam LC and phenolic foam LC-lite. Plant height, hypocotyl length, leaf area, dry weight, and fresh weight were significantly greater in the rockwool medium than those in the other media. However, the T/R ratio and stem diameter were the greatest in the phenolic foam LC than those in the other media. The total porosity and container capacity of the phenolic foam LC was higher than in the other media. The air space (%) was lowest in the phenolic foam LC. Overall, the phenolic foam LC and phenolic foam LC-lite produced seedlings with similar growth as the rockwool. These results suggested that both phenolic foam LC and phenolic foam LC-lite have potential to be used in production of plug seedlings of 'Madison' tomato.

This study analyzed both the effect small and medium-sized suppliers' SCM capacity on the performance and how the moderating effect of demand uncertainty as an environmental factor affects this relation. The study is based on the data collected from the survey of small and medium-sized suppliers operating in electronics, metal, machinery, automobile, and textile. It analyzed the results of survey targeting suppliers of these areas by using structure equation modeling. According to the analyzed result, the relation capital of small and medium-sized supplier affects the performance, but there is no relation between coordination capability and the performance. In case of the moderating effect of demand uncertainty, while there is a positive moderating effect of demand uncertainty between relation capital and performance, there is no any moderating effect between coordination capability and performance. It turns out that the relation capital keep having a positive effect on the performance even if there is a demand uncertainty.

An improved procedure for the rapid purification of glucose-6-phosphate dehydrogenase from extracts of Saccharomyces cerevisiae was developed by using affinity chromatography. Among six affinty media tested, $NADP^+ -agarose$ and Affi-gel Blue were more effective than others (i.e., Affi-gel Red, AMP-agarose, ATP-agarose, and $NAD^+ -agarose$). Conditions to desorb the enzyme bound to the affinity media were examined to increase the purity as well as yield. The best result was obtained when the column was developed with a linear gradient of KCl (0-1.0M). In case of Affi-gel Blue, introduction of $NAD^+$ (15mM) washing step prior to the salt gradient was most effective to remove $NAD^+ -binding$ proteins. For a large scale preparation of G-6-P dehydrogenase higher recovery was obtained by Affi-gel Blue than $NADP^+ -agarose$, however, the purity of the enzyme was decreased by 10 times if the former was used as the affinity medium. The capacity of Affi-gel Blue for G-6-P dehydrogenase was found to be 5 times higher than that of $NADP^+ -agarose$. Furthermore Affi-gel Blue could be reused repeatedly and its preparation is relatively easier and less expensive than $NADP^+ -agarose$.

North Korea classify literature and art according to some concepts and standards. First, as concepts, North Korea classify Literature and Art in a species and a type. But in 1996, North Korea added third concept, a kind of Genre, Galae. This shows us that North Korea attempts to subdivide Literature and Art in classification. But there are not fixed contents in each type. So we can say that North Korea emphasis on principles of classification and at the same time they have a flexible attitude. Second, as standards, North Korea in 1987 used manner depicted, medium employed, capacity, a literary style, figured plot, quality and in 1992 used manner depicted, medium employed, object depicted, a mission, a function and in 1996 used manner depicted, medium employed, object depicted, a form of plot and in 2007 used manner depicted, medium employed, a scale and a capacity of work, a quality of materials and contents, emotional color of works, and so forth. So we can say that North Korea regard classification as an important thing as a basic work for developed Literature and art in future. And to South Korea, classification means that it could suggest a way for creative work for Literature and Art.

This study demonstrated the effect of IT Ssupports for Iintegration Ccompetency(ITSIC) on organizational performance by using organizational temperance and absorption capacity as medium. The research model was verified with Smart PLS 3.0 based on the survey conducted overa total a total of of 126 pparticipantseople's surveys for the employees. First, the ITSIC had a positive effect on both the alignment and adaptability and also on absorption capacity. Second, it was confirmed that organizational temperance hads a positive effect on absorption capacity. Third, when the organizational temperance was mediated in the relationship between ITSIC and absorption capacity, it had a indicated a positive effect. Fourth, absorption capacity had a positive impact on organizational performance. The implications of this study differ from the existing studies through by validating validation of correlations correlations by extending IT technology and organizational performance to organizational ethical factors. In addition, it has been established that the ethical factors of the organization also act as leading factors of absorption capacity. ITSIC helps managers make balanced decision-making, which can contribute to improving absorption capacity by giving members a positive perception, ultimately having a positive impact on organizational performance. It suggests the importance of building appropriate IT infrastructure and cultivating organizational virtues in order to improve the performance of organizations in which absorption capacity is essential.

Although small and medium-size enterprises are facing the significant trends in the Fourth Industrial Revolution and Open Innovation which are increasingly in need, the subjects of absorptive capacity and entrepreneurship has not been studied sufficiently in order to enhance the competitiveness of SMEs' products and cope with the current trend. The purpose of this study is to investigate the effects of absorptive capacity of SMEs on product competitiveness and the moderating role of CEO's entrepreneurship between the absorptive capacity and the product competitiveness. The data were collected from 313 employees of 22 SMEs in the Seoul metropolitan area, Kyunggi-do and Chung-cheong province, and analyzed using hierarchical regression analysis. As a result of the hypothesis test, both the absorptive capacity of SMEs and CEO's entrepreneurship had a positive effect on the product competitiveness. In addition, also found out the innovativeness and the proactivness out of the three entrepreneurship had the moderate roles between the potential absorptive capacity out of the absorptive capacity and the product competitiveness. On the other hand, the risk-taking out of the three entrepreneurship had the moderate roles between the realized absorptive capacity out of the two absorptive capacity and the product competitiveness. These results suggest that open innovation and technological entrepreneurship are needed to help SMEs learn external resources and information to create performance. After discussing this conclusions and implications of the study, the direction for future study was presented.
