In China, the enhancement of water services has become the most crucial issue confronted with the rapid urbanization and industrialization process. A huge financial gap to meet the demand for water infrastructure and need for adopting advanced operation technology precipitated the rapid growth of PPP over the last 10 years. Diverse schemes of PPP such as TOT, Divestiture, and Management Contract and Lease have been practiced. Local governments and private investors/operator have adjusted their objectives and strategies to avoid potential pitfalls behind BOT projects in China. However, current academic research outcomes do not properly reflect important issues of BOT projects or related case studies in China. This limitation has brought in the lack of assessment of important risks and success factors required for the improvement of the body of risk management. In this regard, this study uses the market analysis method to identify major schemes of PPP water projects and conducts case studies on five PPP projects to identify key risk and success factors in association with each different scheme. It is expected that the risk and success factors identified from the cases will be used as reference to Korean companies which plan to enter the Chinese water market.

Purpose - Following the speedy development of the smart phone industry, tourism companies started to increase their brand recognition and sales volume by adopting mobile applications. However, applications for tourism industries are still insignificant. This study tries to analyze empirical evidence from Korean and Chinese consumers who have used mobile tour applications. By using an expansion of the technology acceptance model (TAM), this study will find what factors have effects on user intention for mobile tour applications. The findings will be helpful for the development of mobile tour applications and the tourism industries. Research design, data, and methodology - This study uses the TAM, which was presented by Davis in 1989. This study uses consumer acceptance level, consumer choice attitude, and use intention as the basic variables to fit to the TAM, and adopts choice content quality, brand value, and usage motivation as additional variables to analyze. This study has developed several hypotheses and collected data from 620 users who used mobile applications for tourism during April 1 to April 30, 2015. A total of 612 valid questionnaires were collected and used in the data analysis. The data was analyzed with structural equation modeling using SPSS Win/pc and Amos 22.0. Results - The findings can be summarized as follows: First, the content quality affects the consumer acceptance degree and choice attitude. Second, the brand value has a directly positive effect on the consumer acceptance degree and choice attitude. It is clear that the content quality and brand value play important roles in raising consumer acceptance and choice attitude. Third, usage motivation has no effect on the consumer acceptance degree and choice attitude. Fourth, the acceptance degree does not have any effect on the consumer choice attitude. Fifth, the acceptance degree affects the use intention. Last, the consumer choice attitude affects the use intentions. This indicates that consumer acceptance and choice attitude must both be achieved to induce use intention among consumers. Finally, the effects of the mobile tour application content quality and brand value on consumer acceptance degree and choice attitude were confirmed. Additionally, the effects of the consumer acceptance degree and choice attitude on use intentions were analyzed. Conclusion - It is not meaningful for tourism marketing to launch tour applications in the mobile market without understanding tourism consumer characteristics. When developing mobile tour applications, companies should focus on the characters of consumer choice attitudes as high quality, high brand value, usefulness, and ease of mobile tour applications. This study has limitations in that it did not consider negative factors such as perceived risks or analyze whether there are differences between Korean and Chinese consumers. In the future, we will consider equipping the same mobile tour applications commonly used by both Korean and Chinese consumers, and then examine negative factors as well as the differences in mobile tour applications between Korean and Chinese consumers.

The purpose of this study was to examine the factors which influence the attitude of employees in security firms in Korea that ultimately lead to their turnover. Several variables which are seen as influential in formation of employees' attitudes about their organizations are leadership and job characteristics. In commitment and job stress were seen as two major variables which lead to the formation of their turnover, commitment was seen as positive influential variable and job stress a negatively influencing variable in employees' attitudes about their respective organizations. Survey method using questionnaires were utilized on employees of medium to large security firms in Seoul and Kyonggi province of Korea where 30 or more were employed. Sample for this research were field operators and, for leadership determination, their division chiefs were chosen. For the purpose of this research, several key hypotheses derived and developed from existing works related to this research topic were tested using multiple regression analysis utilizing SPSS 11.0. and Lisrel 8W The research findings are an follows: 1. leadership behavior of the superiors greatly influence, in most positive way, the employees' commitment. 2. Those employees who view their high organization commitment. shown to possess lower turnover. 3. Autonomy in their job characteristics to positively influence one's job stress 4. Higher the job stress the higher and positively influence one's turnover.

Raising the level of quality of the security industry is an urgent matter. Since security service is provided through direct contact with customers, the security agents' expression of emotion directly influences the evaluation of the security company or their own earnings. So emotion control at customers demand is necessary above all things, and this research established what difference the service career makes in the influence that the security agent's emotional labor exerts on customer orientation, and the results of the analysis are summarized as follows. First, the security agent's emotional labor exerted negative effects on customer orientation. From this, the conclusion that the higher the security agent's emotional labor, the lower the customer orientation, was obtained. Second, the service career showed differences in the effects of the security agent's emotional labor on the customer orientation. In other words, the conclusion that the lower the security agent's service career, the greater effects the emotional labor exerts on the customer orientation, was obtained. In conclusion, in order to raise the level of customer service, systematic education to control the emotional labor of the security agents with low service career is necessary. Particularly, since the emotional labor of new employees is related to the service environment, the improvement of the service environment of the security agents is more important than anything else.

Gamma amino butyric acid (GABA), known as a non-protein amino acid and major inhibitory neurotransmitter in the brain, has several functional properties such as neurotransmission, induction of hypotension, tranquilizer, and diuretic effects. The purpose of this study was to isolate and identify lactic acid bacteria, producing high GABA in fermented soy curd. Thirty-two strains of tofu-forming lactic acid bacteria were isolated from kimchi which a traditional Korean food fermented with many kind of microorganism. Among 32 strains, four strains (strain No. 10, 104, 214, 249) formed firm soycurd. In order to select lactic acid bacteria having high GABA producing potential, the isolated strains were cultured in the soymilk and fermented for 48 hr at $37^{\circ}C$. A strain No. 383, which showed highest GABA contents in fermented soycurd, was identified as L. sakei by 16S rDNA sequencing and API analysis, and named as L. sakei 383. L. sakei 383 showed optimal growth up to 24 hr at $35^{\circ}C$ in MRS broth. The optimal time and temperature for GABA production were 18 hr and $35^{\circ}C$ in soymilk. In the optimal condition time and temperature, GABA content of fermented soycurd by L. sakei 383 was 8.65 mg/100 g.

This study analysed the complicated introduction process of IPTV in Korea, based on the rent seeking theory which is one of an useful economic theory for explaining the dynamic interaction between government and entrepreneurs. Rent seeking theory describes the possibility of lobbying for economic regulations or regulatory capture which refers to collusion between firms and the government agencies assigned to regulate them. The introduction of IPTV(Internet Protocol TV) in Korea was the most controversial policy issue since the beginning of new media business of cable TV in 1995. In addition to the ordinary conflict between the old and new entrepreneurs, IPTV caused the bureaucratic conflicts between the Ministry of Information and Communication and the Korean Broadcasting Commission (Two regulation agencies were merged into KCC(Korean Communications Commission) in 2008). Through the process all related policy players, including the government, pursued their own rent, and it caused vicious circle of continuous rent seeking and mutual distrust among players. Finally, all-directional lobby of pre-IPTV companies brought about the successful entrance to IPTV market and the enactment of IPTV special law which includes deregulation compared to the existing Broadcast Act. Considering the convergence trend of media related laws it means going against the times. Until now, the conflict phenomena occurring in broadcast industry were mostly explained based on the sociological conflict theory. However, the result of this study shows the usefulness and necessity of rent seeking theory because it gives an economic explanation of conflict behavior.

The results of this study are the two. First, for convergence technology and convergence technology transfer based on analysis of previous studies I suggested a framework for convergence-type technology transfer conceptualization and measurement. Second, I am compared convergence-type technology transfer to total technology transfer from public research(university and public institute) to SME. Overall, despite the trend to increase technology transfer to SMEs, convergence-type technology transfer is only 4.4%. Both total technology transfer and convergence-type technology transfer to the Industry is active to electronic components, machinery, chemicals, food and beverage, and the medical. The role of universities is emphasized in both total technology transfer and convergence-type technology transfer. There are small transactions of less than 5 million in both total technology transfer and convergence-type technology transfer. Both total technology transfer and convergence-type technology transfer to the region are concentrated in Seoul, Daejeon and Gyeonggi-do.

The SS-epm(N,N '-bis-[2(S)-pyrrolidinylmethyl]ethane-1,2-diamine) ligand having stereospecificity has been prepared and reacted with $CoCl_2{\cdot}6H_2O$ or trans-$[Co(pyridine)_4Cl_2]Cl.$ The resultants are green crystals, both of which are identified to be trans-$[Co(SS-epm)Cl_2]_2(COCl_4)$ by elemental analysis and absorption spectra. CD spectrum of trans complex shows negative (-) cotton effect at long wavelength due to the vicinal effect of the stereospecifically chelated ligands. The conformation of SS-epm in trans complex is ${\delta}{\lambda}{\delta}$(SRRS) for each of the five membered chelated ring. $Co(II)Cl_4^{2-}$ as counter ion plays an importance role in the ionic association of the formation of trans complex with SS-epm. Furthermore, according to orientation of secondary amine, total strain energy on each isomers was calculated by molecular mechanics (MM) to verify structural characterization and spectral data.

The present study attempted to test the effects of using external knowledge services on corporate management performance among SMEs. A survey of SMEs that had used external knowledge services was conducted for the analysis. The findings are as follows. First, regarding government-supported knowledge services for SMEs, knowledge service expert groups' competencies and government's support policies had positive effects on the quality of knowledge services. In particular, the knowledge service expert groups' competencies had more significant effects on the quality of knowledge services than the government's support policies. Second, the quality of knowledge services had significantly positive effects on management performance, whilst confidence-related knowledge service quality factors exerted significant effects on enhancing the relationship with customers and the informationization of knowledge. These findings have the following implication and meaning. The present findings indicate that the government's policy to foster and lay the foundation for knowledge service industry should be furthered, e. g. knowledge service supports for individual companies including knowledge service support projects and systems for SMEs and institutional supports for knowledge service companies and expert groups. In sum, this study is meaningful in that it suggests an effective and efficient policy direction for government's knowledge service provision projects.
