In case of Aju capital, it adopted a strategy to use a single brand not two separate brands after M&A was completed. In order to implement this strategy, it has endeavored to effectively process the work of shifting existing marketing infrastructure of DAEWOO capital, the mergee, spending enough transition time for the brand migration. In the process of merging, Aju capital picked the strategy to use the brand of mergee first, which is the Daewoo Capital brand, and then took a transition time for a while to converge to the single brand of Aju capital. Putting another way, even if the M&A deal was completed back in 2005, it maximized the effect of launching its final brand "Aju capital" by capitalizing on the positive image of "Daewoo" during the transition time and changing its name just in the right moment. In a bid to implement this strategy successfully, it established a cautious but sophisticated brand migration strategy. 1) "Brand bridge" strategy through reinforcing brand power of "Naegeron", which is an individual product brand of Daewoo Capital 2) Establishing a good brand image through reinforcing customer satisfaction 3) It implemented and completed its brand transition initiative by going through the step of Aju Capital brand unification (from Sept 09 to present) Currently, the sales unit of Aju Capital is realizing quality growth through specialization. It's strategy is to construct a systematic sales portfolio in terms of both quality and quantity through product-by-product specialization where the existing practice was selling a variety of products in a single branch. Back in 2009, it opened a branch that specialize in imported cars and expanded its used car business to 6 specialized locations. Besides, the specialized locations for personal loan named "Naegeron" was expanded from 3 to 11 locations. Recently, it is expected that it will inject vigor to retail and corporate financing business alongside with its core business, which is auto financing.

Convergeance in the military operations can be attained by simultaneously integrating effects based on sensor, C2, shooter asset in multi-domain and there is no exception to special operations. However, because of challenges from enemy, terrain, geopraphy, and weather, it's not easy to intertwine effects created from ground, sea, air, cyber and electromagnetic spectrum, and space in special operations conducted in deep area. This study presented how to intertwine high-tech such as long-rane reconnaissance·strike drone, cutting-edge sensor, jamming pod, and modular repeater in order to offset aforementioned challenges. Several new high-tech are able to strengthen convergeance of special operations in accordance with the development of the 4th industrial revolution. Therefore, follow-up studies need to be continued making an efforts to search for them.

Recently, credit risk in the Chinese corporate bond market has increased significantly, and there is a possibility that banks that have invested in corporate bonds may become insolvent. The purpose of this study is to empirically analyze the effect of Chinese commercial banks' investment in securities on financial performance. The analysis results are as follows. First, it is estimated that as the share of securities investment by Chinese commercial banks increases, the bank's profitability decreases. It was found that investment in securities did not have a positive impact on profitability due to the increase in credit risk in the corporate bond market and the increase in marginal companies. Second, it is estimated that as the proportion of securities investment by Chinese commercial banks increases, the bank's soundness deteriorates. As credit risk in China's capital market is increasing, continuous management of non-performing assets is required. Chinese commercial banks need portfolio management through securities investment in addition to loan assets to improve profitability. However, volatility should be managed by adjusting the scale of securities management to an appropriate level.

Consumers demand that corporates fulfill their social responsibility by exerting influence over not only economical values but also social values in markets. Given such a social mood, most corporates are actively engaging in Corporate Social Responsibility(CSR) activities, and marketing scholars continue to study the effects of such CSR activities. Numerous such studies examined the relationship between CSR activity and brand equity. Moreover, virtually, a majority of these studies focused on consumer responses to CSR activity from an individual brand perspective. In a situation in which brand management must consider the spillover effects of brands, firms holding various brands should consider these spillover effects when they establish CSR activity strategies. Therefore, we examine the effects of CSR activity using a comprehensive approach that considers the hierarchy of brands. Additionally, we develop a new perspective on fit that has been used as a major influence on the effects of CSR activity. We argue that the mixed results of the impact of fit regarding the effect of CSR activities is attributed to the influence of connections among brands based on the hierarchy of brands. We then examine the effect of two types of CSR activity strategies that reflect the relativity of fit. The results reveal that there was no difference in impact of the two strategies based on unique roles and traits of corporate brand and effects of low fit. Also, we found that the corporate brand focused strategy creates a greater change in consumers' attitudes than does an individual brand focused strategy in the case of a particular brand. This finding is meaningful because it indicates that a hierarchy of brands may relatively reduce the impact of the role of fit, unlike general arguments from previous related research. Second, the spillover effects from the CSR activities of individual sub-brands belonging to the same corporate brand were confirmed. Therefore, we clearly verified the role of the hierarchy of brands. Although both strategies cause changes in consumer attitude toward brands engaged in CSR activity, overall, a corporate brand focused strategy turned out to be more effective than an individual brand focused strategy because of the spillover effects of brands. Third, this study verified the effect of a corporate brand focused strategy through a moderating effect analysis of the degree of association between individual brands and corporate brand. Given these results, we identified a moderating role in the degree of association and the changes in consumer attitudes toward both main brands engaged in CSR activities and other different individual brands, which were caused by the spillover effects of brands. Finally, this study addresses implications and limitations.

Recently, in the asset management industry, the smart beta strategy, which has an intermediate nature between passive and active strategies, is attracting attention. In this smart beta strategy, value, momentum, low volatility, and quality index are widely used. In this study, we analyzed the quality index which is not clear and complicated to calculate. According to the MSCI methodology, the quality index was calculated using three variables: return on equity, debt to equity, and earnings variability. In addition, we use the index using only return on equity variable, the index using only two variables of return on equity and debt to equity, and the KOSPI index as comparison targets for the quality index. In order to evaluate the performance of the indices used in the analysis, the arithmetic mean return, the coefficient of variation, and the geometric mean return were used. In addition, Fama and French (1993) model, which is widely used in related studies, was used as a pricing model to test whether abnormal returns in each index are occurring. The results of the empirical analysis are as follows. First, in all period analysis, quality index was the best in terms of holding period returns. Second, the quality index performed best in the currency crisis and the global financial crisis. Third, abnormal returns were not found in all indices before the global financial crisis. Fourth, in the period after the global financial crisis, the quality index has the highest abnormal return.

소비자의 욕구변화와 정보기술의 발전으로 정보경제시대, 신경제시대가 도래함에 따라 가치사슬이 변화하고, 새로운 가치를 창출하는 신산업이 등장하고 있다. 인터넷의 확산과 더불어 선으로부터의 자유, 개인성, 즉시성이 가능한 모바일 비즈니스가 우리나라에서도 태동하고 있다. 모바일 비즈니스는 금융업체, 정보제공업체, 통신망 운용업체, 최종이용자간의 새로운 가치의 결합이 특징이며, 막 흐름이 만들어지고 발전되고 있는 상황이다. 이와 같이 다양한 이해관계자가개입하고 있어 협력이 특히 강조되고 또 요구되고 있다. 이러한 중요성에도 불구하고 이들간의 관계에 대한 연구가 미흡한 편이다. 따라서 본 연구는 모바일 비즈니스를 주도하고 있는 통신망 제공업체와 모바일 컨텐츠 공급 파트너간의 조직간 협력관계에 대한 실증 연구를 수행하였다. 관계마케팅, 거래비용, 자원기반관점, 네트워크 이론 등 기업간 관계를 기술, 설명, 예측하는 주요이론에서 논의되고 있는 개념을 바탕으로 본 연구는 컨텐츠 공급파트너의 전략적 성과에 영향을 주는 연구 모형을 제시한다. 최근 중요성이 더 강조되고 있는 항목은 신뢰와 결속임을 감안하여, 매개변수로써 전략적 성과에 영향을 주는 주요한 요소로 신뢰와 결속을 제시하고 있다. 컨텐츠 제공업체의 전략적 성과는 서비스제공업체에 대한 신뢰와 결속에 큰 영향을 받고있다는 점을 반영하고 있다. 한편 신뢰에 영향을 주는 독립변수로는 서비스 제공업체에 대한 평판, 서비스제공업체와 컨텐츠 제공 파트너간의 상호의사소통, 그리고 업무처리의 절차에 대한 공정성을 제시하고 있다 결속에 영향을 미치는 독립변수로는 동의된 목표, 업무정보교류, 거래특유자산의 3개의 변수를 선정하였다. 독립, 매개, 종속변수간의 9개의 연구 가설을 수립하였다. 국내의 주도적인 이동통신망소유업체에 모바일 컨텐츠를 공급하고 있는 170여개의 파트너를 대상으로 실증연구를 수행했다. 공변량 구조분석을 위주로 분석한 연구의 결과에 의하면 본 연구의 모델은 충분한 적합성을 보여주고 있는 것으로 나타났다. 또한 가설의 상당수가 채택이 되었다. 그러나 모바일 비즈니스의 기업간관계의 실제측면을 나타내는 업무정보교류와 결속자의 관계의 유의하지 않게 나와 기각되었다. 기각에 대한 여러 가지의 해석이 가능하지만 측정의 신뢰성을 확보해야 하고 개념의 타당성을 더 엄격하게 준수할 필요성이 제기되었다. 본 연구는 조직이론에 근거한 변수를 채택하고 있으나 모바일 비즈니스의 생명주기특성상 태동기이기 때문에 기업간 관계를 연구하는 측면에서는 탐험적 연구성격이 강하다. 더 나아가 본 산업의 주된 연구가 질적이고 기업내부만을 연구했던 것에 비교하면 시초적이라고 할 수 있다. 또한 관계마케팅, CRM 등의 이론적 배경이 되고 있는 신뢰와 결속의 중요성이 재확인하는 결과도 의의라고 할 수 있다. 그리고 신뢰는 양사 간의 상호관계에서 조성될 수 있는 특성을 가진 반면, 결속은 계약관계 초기단계에서 성문화하고 규정화 할 수 있는 변수의 성격이 강하다고 할 수가 있다. 본 연구는 복잡한 기업간 관계를 지나치게 협력적 측면에서만 규명했기 때문에 많은 측면을 간과할 가능성이 있다. 또한 방법론적으로 일방향의 시각만을 고려했고, 횡단적 조사를 통하고 국내의 한 서비스제공업체와 관련이 있는 컨텐츠 공급파트너만의 시각을 검증했기 때문에 해석에서 유의할 필요가 있다. 또한 타당성확보 노력을 기하였지만 측정도구 면에서 엄격한 개발과정을 준수하지는 못했다. 향후에는 모바일 컨텐츠 파트너의 기업의 특성을 조사하여 관계성 변수와의 상호관련연구를 진행할 필요가 있다. 관계기간, 의존성, 거래처의 단/복수여부, 서비스 범주 등의 제반 변수를 고려하여 이러한 변수가 양사와의 관계성 변수에 어떤 영향이 있는가를 검증할 필요가 있다. 또한 신뢰, 결속 등 다차원의 개념에 대한 심도 깊은 연구와 최근 제기되고 있는 이론의 확대도 필요하다. 마지막으로 신뢰와 결속에 영향을 미치는 요소간의 개념적 분류, 차이의 검증, 영향력 등을 광범위하게 진행시킬 필요가 있다.

Starting from 2010, blockchain technology, along with the development of artificial intelligence, has been in the spotlight as the latest technology to lead the 4th industrial revolution. Furthermore, previous research regarding blockchain's technological applications has been ongoing ever since. However, few studies have been examined the standards for classifying the blockchain economic ecosystem from a capital market perspective. Our study is classified into a collection of interviews of software developers, entrepreneurs, market participants and experts who use blockchain technology to utilize the blockchain economic ecosystem from a capital market perspective for investing in stocks, and case study methodologies of blockchain economic ecosystem according to application fields of blockchain technology. Additionally, as a way that can be used in connection with equity investment in the capital market, the blockchain economic ecosystem classification methodology was established to form an investment universe consisting of global blue-chip stocks. It also helped construct an intelligent portfolio through quantitative and qualitative analysis that are based on quant and artificial intelligence strategies and evaluate its performances. Lastly, it presented a successful investment strategy according to the growth of blockchain economic ecosystem. This study not only classifies and analyzes blockchain standardization as a blockchain economic ecosystem from a capital market, rather than a technical, point of view, but also constructs a portfolio that targets global blue-chip stocks while also developing strategies to achieve superior performances. This study provides insights that are fused with global equity investment from the perspectives of investment theory and the economy. Therefore, it has practical implications that can contribute to the development of capital markets.

With the realization of the importance of the NWI, iterated by the Cheonan Ship sink and the YP-Do shelling, this thesis separates the NWI from the peninsula, regarding it separate from the Korea Theater of Operations, and suggests the method to establish NCOE with consideration to the characteristics of separated theater as well as the current situation. Although the NWI holds strategic value, systematical NCOE of surveillance and reconnaissance system, command and control system, and precision strike system is not yet established. Pertaining to this issue, Architecting was utilized to identify improvement measures and of the identified improvement measures, improvement on the "strike on nK hardened artillery sites with K-9 Self-Propelled Artillery in correlations with theater ISR" shows greatly improved strike effects when conducting simulations based on the Operation-Plan Analysis Model. Such a method of NCOE establishment will serve as a standard model for military force building and operation execution system for separated theater operations such as the NWI.
