This study investigates time series data on internet banking systems and business performances for 5 large-scale banks : Kookmin, Woori, Hana, City, Shinhan. These banks have the common features that they merged with other banks around 2000, hence they experienced massive IS integration between banks. This study adopted VAR and VECM for identifying Granger causality between the quality of internet banking systems and the performances of banks(operating revenue and cost). The main results are as follows. First, internet banking system impacts positively on the revenues as well as costs of banks. Second, the improvement of internet banking system is instigated by cost part more than revenue part. Hence, the results imply that banks tries to reduce operating costs via internet banking systems, however the systems rather increased the costs of banks, although the systems increased operating revenues of banks too.

This study analyzes the characteristics of customer's preferences on banking channels (branches, automated machines, telebanking, internet banking, and mobile banking) and examines the factors influencing channel usage. To accomplish this, ANOVA and multiple regression analysis are performed using customer data from Bank A. The analysis reveals that customers primarily utilizing branch counter transactions have a significant impact on the profitability of 1st and 2nd grade banks, particularly among the age group of 50 years and above. Additionally, it is observed that as customers' loan, deposit, and financial product holdings increase, branch counter transactions also increase. On the other hand, it is found that as the usage of mobile banking decreases in terms of loans and deposits, transaction volume increases.

본 논문에서는 온라인 전자현금 시스템을 설계하고 개발한다 개발된 전자현금 시스템은 공개키 알고리즘, 맹목 서명, tut-and-choose등과 같은 다양한 암호화 기법들이 사용되어 안전성을 높였으며 특히, 전자현금의 이중 사용(double spending)의 효과적인 방지를 위해 2중 은행 구조(2-level bank structure)를 취함으로써 통신망을 오가는 트래픽의 양을 많이 줄이고자 하였다. 이 구조의 가장 큰 특징을 각 은행마다 그 은행에서 발행하는 전자현금을 구분하기 위해서 전자 현금의 정보에 들어 있는 일련번호(sequence number)의 값을 은행별로 범주화한다는 점과, 이를 지원하기 위해서 각 은행마다 Cash Clearing Agent라는 모듈을 가진다는 점이다.

본 연구의 목적은 지난 2004년에 공표된 바젤II 규정에 의거 각국 은행들에 대한 체계적인 위험관리가 강화되는 상황에서 최근 국내 S은행에서 은행권 최초로 기존의 DRP(Disaster Recovery Planning)차원을 넘어선 전행 차원의 BCP프로세스를 구축하게 되었다. 여타 은행들도 대형 재난 및 바젤II 규정등에 대비해 금명간 체계적인 BCP시스템을 갖추게 될 것인바, 이러한 BCP시스템의 구축에 따른 효과로 실제 재해 상황에서 이러한 시스템이 은행의 안정적인 업무수행을 보장하는데 그 주된 목적이 있겠지만, BCP 프로세스에 포함된 내용으로서 BIA(Business Impact Analysis)를 통한 RTO(Recovery Time Objectives), 그리고 BCP 프로세스의 추진으로 은행의 여러 이해관계자들에게 미치는 영향등을 고려해 은행원들의 평시 업무수행절차나 프로세스등의 개선등을 통해 은행원들의 직무만족도에 어느 정도 영향을 미치는지 살펴보고자 한다.

This study empirically analyzes whether bank capital channel and risk-taking channel for monetary policy work for domestic banks in South Korea by analyzing the impact of the expansionary monetary policy on the rate spread between deposit and loan, capital ratio, and loan amount. For the empirical analysis, the Uhlig (2005)'s sign-restricted SVAR(Structural Vector Auto-Regression) model is used. The empirical results are as follows: the bank's interest rate margin increases, the capital ratio improves, risk-weighted asset ratio increases, and the amount of loans increases in response to expansionary monetary shock. This empirical results confirm that bank capital channel and risk-taking channel work in domestic banks, similar to the previous research results. The implications of this study are as follows. Although the expansionary monetary policy has the effect of improving the bank's financial soundness and profitability in the short term as bank capital channel works, it could negatively affect the soundness of banks by encouraging banks to pursue risk in the long run as risk-taking channel works. It is necessary to note that the capital ratio according to the BIS minimum capital requirement of individual banks may cause an illusion in supervising the soundness of the bank. So, the bank's aggressive lending expansion may lead to an inherent weakness in the event of a crisis. Since the financial authority may have an illusion about the bank's financial soundness if the low interest rate persists, the authority needs to be actively interested in stress tests and concentration risk management in the pillar 2 of the BIS capital accord. In addition, since system risk may increase, it is necessary to conduct regular stress tests or preemptive monitoring of assets concentration risk.

Korea came to see its first internet bank as 'K bank' obtained the digital-only banking license in December 2016. This paper suggests ways to foster internet banks of Korea in their early stage by analyzing the successful cases of overseas internet banks. The followings are the key success factors identified from those cases across Europe, Japan, China, and USA: Support from the related government authorities; Stable governance structure; Distinct business capabilities based on information & communications technology(ICT). These points lead to the following implications for Korean internet banks. Regulatory restrictions on owning and running internet banks should be lifted to facilitate innovation. Policies to support internet bank industry should be introduced as it is a vital part of the 4th industrial revolution. Finally, internet banks should strive to differentiate themselves by utilizing their ICT capabilities. Subjects of the further research hereafter should include the following: Analyzing the ongoing performance and developments of digital banks in Korea; Deriving success factors from the analysis; Assessing the influence and effects on financial market and economic environment.

본 연구는 확률 프런티어(stochastic frontier) 분석방법을 사용, 1995년부터 1999년까지 한국, 미국, 일본의 136개 상업은행을 대상으로 효율성을 추정하였다. 분석결과에 의하면, 국내 은행의 효율성은 미국, 일본에 비하여 큰 차이가 나지 않았으나 금융위기 이후 급격히 떨어졌으며, 이후 다시 효율성이 향상된 모습을 보이고 있다. 반면 같은 기간에 국내 은행만을 대상으로 추정한 결과는 효율성의 큰 변동을 감지하지 못하고 있다. 이는 지역경제 전반에 걸친 충격이 있을 경우 국제비교를 하는 것이 타당함을 시사하고 있다.

An internet primary bank, which is formed by internet and banks combined, is called the essence of fin-tech, and is currently experiencing rapid growth. 'K-Bank' and 'Kakao Bank', the representative internet primary banks this year, received positive responses as the origin of financial revolution. internet primary banks provide convenient financial services, benefits in time and money for customers. Not long ago, however, undesirable fraud cases caused by a used commodity dealer have happened. The damage exceeds 20,000,000 won. It is because the newborn banks are unable to check the fraud history through the bank account. In this paper, We will analyze the trend in internet primary banks, offer damages and examples, in addition, prevention of damage, and strategies for development.

This study was conducted to find potentialities of the leaves of gingko tree (Gingko biloba L.) which has been planted as a roadside tree in Korea because of its resistance on air pollution, insect, fungi, etc. Various amounts of the leaves were mixed with wasted wood particles to manufacture particleboard. Their influences on physical and mechanical properties and the formaldehyde emission of PB were investigated. Physical and mechanical properties, such as density, modulus of rupture (MOR), and internal bond (IB) strength, of manufactured particleboard were not much different from those of control board. Formaldehyde emission values were decreased with increasing amount of leaves in PB prepared. Especially, particleboard made with 3 percent of leaves was decreased to $1.66mg/{\ell}$ in formaldehyde emission, which is about 40% lower emission than that of control. From these results, the leaves of gingko tree may be considered as a formaldehyde emission lowering additive in a functional PB manufacturing process.

When banks prefer securities holding to lending, bank-dependent borrowers would be rationed in bank loan markets. This paper examines, both theoretically and empirically, the incentive of banks to hold securities rather than loans. When banks are in trouble due to an external shock and subsequent drain of deposit, they cannot reduce their loans quickly because loans are illiquid and are not easy to sell. Therefore, banks should respond to insured deposit drain by raising uninsured CDs or debentures. However, they cannot raise enough money through uninsured CDs or debentures when there is costly external finance premium. Meanwhile, if banks hold securities which are highly liquid, they can sell those securities and thus endure deposit drain without costly external financing. This explains why banks hold liquid securities of which yields to maturity are lower than those of loans. Banks' preference for securities comes from the existence of costly external finance premium, which is inversely related with bank net worth. After all, if bank net worth is kept high enough or capital market incompleteness is not severe, the preference for securities should be weakened.
