MOCT(Ministry of Construction & Transportation) suggested 'A Plan for Implementation of Knowledge-based Economy for the Construction Industry' to add high value to the construction industry by means of knowledge-based management techniques. However, there are no guidelines which help the bodies of the construction industry(government, research center / university, enterprise, etc) with doing a knowledge management. So it is difficult to implement the knowledge management systems for the construction industry. To establish the knowledge portal for the construction industry, the objective of this study is to present works, which help the bodies of the construction Industry(government, research center/university, enterprise, etc) with doing knowledge activities efficiently. To accomplish this objective, we analyzed the overall knowledge management activities. And we suggested an implementing direction of the knowledge management systems for the construction industry and a strategy for implementing the knowledge management systems in the construction industry. As results of this study, we established a strategy of knowledge management and works of the bodies of the construction industry(government, research center / university, enterprise, etc) We expect that the results of this study will be used as a manual of the bodies of the construction industry for implementing knowledge management systems and the knowledge portal that brings the construction industry to high value added industry.

The antioxidative and antimicrobial activities were determined on the mushroom (Sarcodon aspratus) extracts in order to find out new food functional components. The antioxidative activities of water and ethanol extracts from the Sarcodon aspratus were measured by peroxide values (POV), electron-donating ability (EDA) using 1,1-diphenyl-2-picryl hydroxyl (DPPH), nitrite-scavenging ability and superoxide dismutase-like activity (SODA) by pyrogallol. The antioxidative activity of the ethanol extract measured by POV was higher than those of the water extract, BHT, and ${\alpha}-tocopherol$. The EDA of the water extract and ethanol extract using DPPH showed the highest values of 76.94% and 73.06%, respectively. The nitrite-scavenging abilities (pH 1.2, 1,000 ppm) of the water and ethanol extracts were 72.61% and 62.69%, respectively, and the nitrite-scavenging ability of the water extract was higher than that of the ethanol extract in all pH values. The SODA of the ethanol extract was higher than that of the water extract. The Sarcodon aspratus extracts had antimicrobial effects on Listeria monocytogenes and Staphylococcus aureus.

The purpose of this study is to analyze the effects of mergers and acquisitions of domestic IT companies on strategic aspects of internal capacity enhancement. Empirical analysis applied to this study analyzed the business performance in the market through the merger of Daum Communications and Kakao Group. After Daum pursued the merger with Kakao, it showed that the platform business of kakao is expanding to the domain of the existing portal site. The merger was completed, and the total value of the stocks went up to the highest level, but soon its value declined. The merger shows that the growth potential of the enterprise is temporarily declining, which seems to be the internal cost of the merger. Even in the case of profitability, the merger did not show positive results. In the case of stability, the expectation due to the merger was reflected and slightly increased. The following two companies were interested in the kakao when they viewed the merger through a chronological analysis. However, after the merger, the interest of the next kakao was similar. This is seen as a result of the expansion of kakao's diverse platform business rather than the following search sites. From the results of this study, it is suggested that domestic IT companies should approach by analyzing the strategic factors that generate synergy when pursuing M & A to strengthen their resources or capabilities.

This study was conducted to investigate chemical properties of wild $Lactuca$ $indica$ (WL) and cultivated $Lactuca$ $indica$ (CL). The proximate composition, reducing sugar, free amino acids, organic acid, vitamin C, minerals, chlorophyll, and crude saponin were analyzed. WL and CL contained high levels of carbohydrate. The leaves and roots of CL contained higher levels of free amino acid than those of WL. Especially, the proline content of CL leaf was 12 times higher than that of WL leaf, and the arginine content of CL root was 100 times higher than that of WL root. The major organic acid and mineral of $Lactuca$ $indica$ were tartaric acid and potassium, respectively. CL showed significantly higher value of reducing sugar than WL. The vitamin C content of the samples ranged from 0.4 to 24.1 mg%, and CL leaf was the highest amount of vitamin C among the samples. CL leaf had a higher amount of chlorophyll than WL leaf, but WL root contained a higher amount of crude saponin than CL root. As in this study, CL showed better nutritional properties than WL, and these results will provide fundamental data in order to activate the cultivation of wild plants.

In 1988, the government provided to the low income people 34.1% of the stocks of Pohang Iron & Steel Company through the People's Share Program of Privatization for the first time, and then in 1989 21% of the share of the Korea Electric Power Corporation were also provided to the low income classes through the same way. The purpose of the People's Share Program was known to be to support the low income classes through participating the profit of public enterprises, and also to expand the capital market through the diversification of stock holding structure. Initially, the government planned that the government share of enterprises such as the Citizens National Bank, the Korea Telecommunication Authority would be sold to the low income classes through the People's Share Program step by step. The income support policy, however, was no longer driven after 1989 when the overall stock prices started to decline. In this paper we tried to measure the effect of the privatization scheme of the public enterprises through the People's Share Program. The problems of the People's Share Program of the Pohang Iron & Steel Commpany and the Korea Electric Power Corperation were also identified. Several implications of the privatization scheme of the public enterprise through the People's Share Program by stages were found. The People's Share Program was found to be a non-stable policy measure for the income support of low income classes. The efficiency impact of the privatization through the People's Share Program was found to be non-significant.

In order to create value for maritime tourism industry, new port infrastructures have been planned, improvements in passenger terminal services have been designed, and new maritime transport technologies have been applied, so that ports improve their efficiency and the quality of their service more than their national and international competitors. Thus, the purpose of this study is to verify the dimensions of the service quality of ocean passenger terminal. Based on a survey of 260 customers in port of Busan and Inchon, terminal service quality's five main dimensions have been checked regarding their fit with the use of Confirmatory Factor Analysis. Empirical results support that this is a valid instrument for measuring service quality of a ocean passenger terminal. The interactive sequence of computing Cronbach's alpha, corrected item-to-total correlation, and factor analysis was repeated a few times and resulted in a final set of 19 items representing five distinct dimensions-tangibles, responsiveness, knowledge, reliability, and accessibility. This finding provides the more appropriate instrument to evaluate the customers perception as well as to measure the service quality of ocean passenger terminal.
