While the Chinese banks have started the impact of foreign banks. At the same time, rising pressure on foreign exchange reserves and appreciation of the renminbi has prompted Chinese banks to go abroad and diversify their risks. The financial crisis of 2008 has caused the continued turbulence of the major financial markets around the world, and the valuation of foreign financial institutions has been drastically shrinking, providing opportunities for Chinese banks to carry out overseas M&A. Based on the overseas M&A status of Chinese commercial banks, this paper sums up the characteristics of the overseas M&A. Then taking a series of overseas M&A conducted by ICBC from 2006 to 2011 as an example, it analyzes the relationship between M&A and performance growth using grey incidence model. The test shows: there is a positive correlation between both overseas M&A and interest rate differential with performance growth of ICBC, and overseas M&A transactions role in promoting the performance growth is significantly higher than the interest rate differential.

This study raises the question about why do many international fisheries organizations or regional fisheries agreements come into existence, sustain, and develop prior to the internationally recognized institution such as United Nations Convention on the Law of the Sea(UNCLOS). In oder to solve the problem, I will investigate the characteristics of fisheries as renewable resources and propose the collusion model where it is based on the cost-benefit analysis. Especially, if once a fooall large number of fishing is implemented, they are immediately depleted. Consequently they are extinct and no longer exploitable. Thus each interest nations or participants will be better off if they are cooperative and will be worse off if they are competitive or noncooperative in a resource management. Therefore, many of the internationally recognized fisheries institutions and agreements have been made and developed in these days.

This study investigates the factors determining accounting method for R&D costs (capitalizevs. expense) in Korea. Using agency theory and other economic factors, probit and regression model have been developed to distinguish between firms choosing different accounting alternatives for R&D costs. The results are consistent to debt contract, R&D burden and regulation hypotheses both in probit and regression analysis. The size variable has opposite sign in univariate t-test and probit analysis, which may be due to the differences of political environment between Korea and the US. Generally, the results are consistent to those of previous research. The evidence suggests that larger firms with higher leverage and larger burden of R&D costs are more likely to capitalize R&D costs, while regulated firms are more likely to expense R&D costs.

The purpose of this study was to clarify the model of fashion change related to the cyclical variations suggested by Kroeber and Young and the selected social changes factors since Kapokyungchang(1894) in Korea. The sample was drawn from illustrations and photos in newspapers and magazines such as Chosunilbo, Dongailbo, and Yeowon. Documentary research and a content analysis have been done. The results were as follows : 1. Cyclical variations in dress were apparent for skirt length and silhouette. However, Kroeber's model and Young's model that regulary recurring cycles exist did not fit the data for 1970 to 1990 in Korea. For skirt length, the cycles appeared to be approximately five to six years for 1970 to 1990. 2. Social and institutional factors tended to account for more the variance in dress dimensions than political factors.

Development of information and communication technology is changing commerce environment and consumer purchasing behavior has also been changed. Globalization is becoming increasingly prevalent in the world today and many factors such as culture, politics, and economics may influence the applicability of management theories. Concurrently, corporate managers are faced with the challenge of offering usable and useful applications to the local users. Besides, many scholars strongly support that the criteria for M-Commerce adoption in developing countries are different from that of developed countries, due to cultural, security, social, political, economic, and technological aspects. This research tried to investigate the differences on the adoption of mobile commerce between developed and developing countries. In this study, the motivation for studying advanced mobile phone services adoption in the South Korea and Viet Nam is presented. Second, M-Commerce adoption model is introduced as a starting point for the research model. We then integrate price, personal innovativeness, quality dimension and perceived of playfulness into our model. Next, we describe our method and report the results of our analysis. The paper concludes with a discussion of the results from both the South Korea and Viet Nam with implications.

본 논문은 러시아 현지에 진출하여 직접 경영활동을 수행하고 있는 한국기업들이 직면하고 있는 정치적 환경요인이 무엇인가를 규명하고 이에 어떠한 대응책을 마련하여 경영활동을 전개하고 있는 가를 밝히기 위한 것이라 할 수 있는데, 이를 위해 구조방정식모델링 기법을 사용하였다. 또한 기업의 경영활동에 영향을 미치는 일반 환경요인과 산업 환경요인 중에서 일반 환경요인으로 연구의 대상을 제한하였다. 그 이유는 기업이 오히려 일반 환경에 대한 분석을 체계적으로 실행하고 있지 않다는 지적이 있기 때문이다. 그리고 일반 환경요인 중에는 문화적 환경요인 등의 변수들은 제외하고 정치적 환경요인만을 분석에 대상에서 포함시켰는데 기업의 현지경영활동에 가장 직접적이고 가시적인 영향력을 행사하기 때문이며 동시에 연구결과의 효율성을 제고하기 위한 것이다. 분석 절차로는 선행연구를 통해 문헌분석을 실행하고 이를 토대로 연구가설을 설립한 후 이를 검증하기 위한 실증분석을 실시한다. SPSS 12.0 for windows를 이용하여 상관분석, 신뢰성 타당성 분석을 실행하고, 구조 방정식 모델링을 통한 경로분석은 AMOS 7.0 for windows 통계프로그램을 활용하였다.

본 연구는 통일한국에서 남한 중심으로 추진되는 통일정책을 분석하고 북한 주민들이 소득재분배와 관련한 의사결정에 참여할 때 어떤 정책이 채택되는지 살펴본다. 구체적으로 두 가지 정책을 분석한다. 첫째는 남한 중심의 이주 및 재분배정책으로서 남한의 중위 투표자가 가장 선호하는 이주 비율과 세율이 채택된다. 둘째는 북한이 참여하는 재분배정책으로서 이주가 자유롭고 통일한국에서 중위투표자가 세율을 선택하며 동 세율이 남북한 모든 주민들에게 동일하게 적용된다. 북한 주민들의 남한 이주문제를 명시적으로 분석하기 위해서 이주 의사결정을 내생화한다. 남한으로 이주를 선택하지 않는 북한 주민들은 새로운 정부를 구성하거나 통일 직후 남한으로부터의 재정 독립을 선언할 수 있다. 본 연구에서는 남한 중심의 재분배정책 하에서 소득재분배가 이루어지지 않는다는 것을 보인다. 북한의 중위투표자는 소득재분배가 이루어지지 않는 상황에서 재정독립을 통해 자체적으로 소득재분배를 수행하는 것을 선호한다. 북한 참여 정책 하에서는 보다 적극적인 재분배 정책이 이루어지고 재정독립이 일어나지 않는다는 것을 보인다.

Emerging attacks aim to access proprietary assets and steal data for business or political motives, such as Operation Aurora and Operation Shady RAT. Skilled Intruders would likely remove their traces on targeted hosts, but their network movements, which are continuously recorded by network devices, cannot be easily eliminated by themselves. However, without complete knowledge about both inbound/outbound and internal traffic, it is difficult for security team to unveil hidden traces of intruders. In this paper, we propose an autonomous anomaly detection system based on behavior profiling and relation mining. The single-hop access profiling model employ a novel linear grouping algorithm PSOLGA to create behavior profiles for each individual server application discovered automatically in historical flow analysis. Besides that, the double-hop access relation model utilizes in-memory graph to mine time-sequenced access relations between different server applications. Using the behavior profiles and relation rules, this approach is able to detect possible anomalies and violations in real-time detection. Finally, the experimental results demonstrate that the designed models are promising in terms of accuracy and computational efficiency.

This study analyzed the factors affecting economic growth using multiple regression model and Geographically Weighted Regression in consideration of population, industry and employment, housing and political characteristics on economic growth by region. The analysis results are summarized as follows. First, the total employment growth rate, manufacturing employment growth rate, local election turnout and the level of party consensus between the central and local governments are having a positive impact on regional economic growth. Second, according to the GWR analysis, the population has a positive impact on economic growth in the southern region of Korea, and the increase in the total number of employees has a positive impact on the southern region of Gyeonggi Province, Gangwon Province, North Chungcheong Province and North Gyeongsang Province. Finally, the voter turnout of urbanites is positively affecting economic growth in South Chungcheong Province, Gangwon Province and the southern coast, while North Jeolla and South Jeolla provinces have a positive impact on economic growth as the parties of the central and local governments are equal. The results of this study may suggest the role of local government for regional economic development.

Weapon systems are curcial instruments for the security of a nation and critical elements for the victory in a war. Since modern weapon systems tend to be capital-intensive with high precision and quality, they become more and more complex and diversified; their acquisition costs become huge; and their technological obsolescence becomes accelerated. Therefore, the systematic management of weapon acquisition process would be one of the most important defense tasks at the national level. To analyze such problems and find solutions, this paper has studied various aspects related to the efficient management of weapon system acquisition. After brief summarization of the general characteristics of weapon systems, their effectiveness, and developmental trend, the paper discusses the defense management policies and techniques for the weapon systems. Specifically, four alternative acquisition methods such as indigenous R & D, foreign purchase, co-production and joint-production are discussed and analyzed by systems approach. The systems analysis procedure to evaluate and select weapon acquisition method is as follows; 1) to analyze the merits and demerits of the alternative methods, 2) to screen unrealistic alternatives through the consideration of significant factors such as political, economic, military, technological, and social constraints, 3) to evaluate and select an optimal one among the remaining acquisition methods after the cost-effectivenss analysis. For the base of cost-effectivess analysis, cost analysis model as well as effectiveness analysis model of each acquisition method are developed.
