Banks traditionally focus on the financial services against the uncertain future liquidity needs, i.e. saving as well as lending. As the business model of banks has been shifted from the originate to hold model to the originate to distribute model since the enactment of Gramm-Leach-Bliley Financial Services Modernization Act in 1999, the financial services encompass information gathering and generating, underwriting and risk sharing through packaging claims for the investors, in addition to the payment and settlement services. Ensued are the financial market integration and diversification of financial services, with which the accessibility to financial services is arguably significantly enhanced. Such integration and diversification necessarily entails the risk of contagion due to the non-fulfilling service over the several other financial services, which would be contained easily under the separate financial services. This paper addresses the pricing of fees for the integrated financial services through which the contagion could spread when the users of financial service are not immune to the failure to fulfill their obligation due to the economic turmoil. Consequently the information asymmetry about the clients is unavoidable. Higher fees could drive out the otherwise good clients out of the pool of customers for the financial services. Then, the risk could be exacerbated due to the proliferation of bad clients who are vulnerable to the financial distress and liquidity crunch. So the banks should take into account the interactional effect of the fees between/among the non interest based activities and interest based activities under the information asymmetry. Contrary to our general perception, the current analysis demonstrates that the bank should focus on the reduction of cost associated with good clients rather than that of bad clients.

Many firms have had a passion for IT investment for years. Despite such a continuing investment in IT, the application of newer technologies to business work doesn't guarantee a great success. Some IT projects were doomed to failure or ineffectiveness. What could we do to lead IT project to the territory of effectiveness? One plausible and inevitable avenue is enterprise architecture (EA), which requires one to first come up with a simplified view of the complex entity to be designed and then proceed to design and develop it as directed by the architecture. Though there have been more materials on such EA work and real cases, there still exist a doubt about why EA is needed and how a firm can introduce it. This article first presents a structured understanding about EA and then describes the necessity, and the introducing ways of EA.

Because of operating and ordering vessels over 10,000 TEU, the strategic alliance between liner shipping companies will be diversified and activated more briskly to secure cargo quantities, minimize costs, secure profits, improve service quality and manage stable business. Many of prior studies concerning strategic alliance are carried out to clarify success factors, motives or to explain how to select a good partner for success. But over 70% of strategic alliance has been resulted in failure. Because failures of strategic alliance occur much more frequently than success, negative effect factors in strategic alliance have to be measured and be adapted to changing conditions in the shipping market. To improve negative effect factors, shipping companies should make an effort to establish reliable relationships between partners and suppress claims by clearing off imprecise contract terms. And it is necessary to increase satisfaction of each individuals and minimize complexity occurred due to the exterior relationships for the successful strategic alliance.

The human resources of an enterprise is very important to survive in these days of business environment. This study investigates the influence of four behavioral types in MBTI (Myer-Briggs Type Indicator) and working conditions on organizational effectiveness. Job satisfaction and immersion have been regarded as a key conception of organizational effectiveness. The focus of this study is to investigate the effects of R&D employee's four behavioral types in MBTI and working conditions on organizational effectiveness. The results of this study show that organizational effectiveness is influenced by personality types and working conditions. According to the result, First, about the analysis of differences in job satisfaction, EP (Extraversion Perceiving)-type (3.56) and EJ (Extraversion Judging)-type (3.43) are higher than IJ (Introversion Judging)-type (3.07) and IP (Introversion Perceiving)-type (3.03) of four behavioral types in MBTI. So an enterprise makes various efforts to enhance job satisfaction for IJ (Introversion Judging)-type and IP (Introversion Perceiving)-type. Second, For improving the organizational effectiveness that is job satisfaction and immersion, an enterprise must make favorable working conditions to each four behavioral types in MBTI of R&D employees. In order to improve job satisfaction, the enterprise will provide IJ (Introversion Judging)-type with support for collegiality and IP (Introversion Perceiving)-type with good relationships with superiors. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type. Finally, in the case of EP (Extraversion Perceiving)-type, the enterprise must admit failure for efforts. In order to improve job immersion, the enterprise will provide IP (Introversion Perceiving)-type with good relationships with superiors, the vision of company and compensation for creative work. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type.

Recently, nuisance tripping or malfunction of MCCB(Melded Case Circuit Breaker) and ELB(Electrical Leakage Breaker) is being increased according as load circuits and equipments of electrical customers are various and complicated, but investigation of actual conditions on malfunction of MCCB and ELB was not implemented This paper investigated causes and influences of malfunction of MCCB and ELB by making up a question to electrical safety managers of two hundred and eighteen private electrical facilities. The results show that users above $70[\%]$ experienced malfunction of MCCB and ELB, and causes of malfunction are in order aging(above $25(\%)$), nuisance tripping $(above\;22(\%))$, goods badness$(above\;20(\%))$, abnormal power like as harmonics$(above\;20(\%))$ and others $(about\;9(\%))$. Also, second damages due to failure of MCCB and ELB are in order goods production, equipment trouble, information loss, business and operation interrupt, and others. The results of this study can be used in making decisions regarding causes of MCCB and ELB trip.

Purpose - With growing competition in the service distribution industry, the importance of managing customer complaints has increased. If firms handle customer complaints effectively, they can strengthen customer loyalty and repurchase intention. Many studies have focused on customers expressing complaints, yet research on silent customers is scant. This study focuses on two types of complainers and non-complainers. In other words, this study is to examine the value of voice complaint intention and no-action intention. This study also investigates how perceptual and relational factors affect complaint intention. Research design, data, and methodology - This study was carried out using the survey with undergraduate students who have faced a service failure in a retail store(fast foods, electronics, apparel). And if such complaint were to occur again, respondents were asked about any possible action they would take. 300 questionnaires were distributed and a total of 279 respondents provided complete and usable data. The sample consisted of 158 males(56.6%) and 121 females(43.4%). The structural equation modeling analysis was used for the hypothesis test. Results - The results are as follows. First, attitude toward complaining, likelihood of successful complaint, and ease of complaint were positively related to voice complaint intention. Second, attitude toward complaining, likelihood of successful complaint, and ease of complaint were negatively related to no-action intention. Third, commitment was positively related to voice complaint intention but didn't have a significant negative impact on no action. Forth, voice complaint behavior reduced switching intention and no-action intention enhanced switching intention. Conclusions - The findings of this study confirm the value of complaint behavior and show voice complaint intention and no-action intention should be managed differently. Voice complaint intention is evaluated positively because it reflects customers' concerns about the company, while no-action intention is evaluated negatively. Attitude toward complaing is the most effective in increasing voice complaint intention and likelihood of successful complaint is a major factor in reducing no-action intention. Also, in explaining switching intention, voice complaint intention plays a more important role than no-action intention.

This paper examines and estimates GARCH-VaR models (RiskMetrics, GARCH, IGARCH, GJR and APARCH) with three different distributions such as Gaussian normal, Student-t, Skewness Student-t Distribution using the daily price data from Korean Stock Market during Jan. 1, 1980-Sept. 30, 2004. It also compares them. In-sample test, this finds that for all confidence level as $90%{\sim}99.9%$, the performance and accuracy of IGARCH with ${\lambda}=0.87$ and skewness Student-t distribution are superior to other models and distributions in long position, but GARCH and GJR with Skewness Student-t distribution in short position. For above 99% confidence level, the performance and accuracy of IGARCH with ${\lambda}=0.87$ in both long and short positions are superior to other models and distributions, but Skewness Student-t distribution for long position and Student-t distribution for short position are more accuracy and superior to other distributions. In-out-of sample test, these results also confirm the evidences that the above findings are consistent as well.

To analyze the effects of R&D expenditure on the firm value of Korean firms, we classified portfolios based on R&D activity levels. After that, we conducted a time-series analysis to assess excess returns from the portfolios. To carry out such an analysis, an empirical analysis of excess returns in the capital market was performed by using the monthly earning rate of stocks from 2000 to 2013. The purpose of this research is to provide basic data on investment to stakeholders in the capital market by analyzing the effects of R&D on the firm value and to overcome scholarly limitations by offering a new model of analysis. The criteria for classifying the portfolios were based on R&D expenditure levels. The analysis models follow the Fama-French Three-Factor Model and the Carhart Four-Factor Model. The analyses results are as follows. Extrapolating monthly profit rates based on R&D expenditure levels, portfolios with low R&D expenditures showed higher earning rates than those with high R&D expenditures. This suggests that high R&D expenditures did not translate into high earning rates. The investor depreciates the R&D expenditures related profitability and the possibility of success in the market, leading to falls in stock prices and a failure to give a positive effect on the firm value. Our research differs from the previous investigations as we carried out an empirical analysis based on the actual investors' attitudes about R&D expenditures and how these can generate excess earnings. Our research results show that the data related to R&D expenditure are not reflected fully in the market.
