With most major full service banks having launched transactional Internet banking, attention is shifting to the realities of managing the Internet channel as a profitable component of an overall delivery strategy. In addition to examining Case Study and Internet Bank Model. Services of Internet Banking available through the Internet are as follows. 1. credit card loans, personal loans. 2. high-yield financial products. 3. insurance products. 4. securities products. 5. Case study of Foreign Internet Banking(ING, BNP, HSNC, City Bank). The study reviewed fields, including financial services, customer service, Website formation and design, convenience of use and system safety, Internet Banking Model, and many related areas. Internet Banking earned high marks in most fields. This study review focuses on the following: Understanding and meeting consumer expectations for us ability, site performance and functionality.

The rapid progress of computer networking technology is changing the environment of today's business and its influence is spreading out widely. Although the practical use of business system using the internet technology is providing easy going infrastructures, many security problems of data or equipment in the open field will be exposed if we do not give serious considerations to their securities. In this paper, we suggest advanced methods to measure the network security capability with considerations for the security of data or equipments.

This paper investigates various channels through which liquidity can affect stock returns and examines whether behavioral explanation for liquidity risk is reasonable. First, we examine whether liquidity level (average liquidity) plays a significant role in determining asset returns. The result is consistent with the hypothesis that a stock with higher average illiquidity will have a higher expected return. Second, we focus on the argument that liquidity has a non-diversifiable systematic component. If systemic liquidity has a different impact across individual securities, a stock that is more sensitive to systematic liquidity will have a higher expected return. The results of various tests are inconsistent with each other, not completely supporting the argument. Finally, the intra-market tests in Korea support the behavioral explanation for the liquidity premium, and the effect is stronger in the liquidity level than in the liquidity beta related to systematic liquidity.

We produce a photosensitive convex plate to research a Nickel metal relief printing plate using galvanic process. A Method for preparing DLC convex plate that is metalized on Nickel metal relief printing plate using CVD(Chemical Vapor Deposition) process and $N_2DLC$-convex plate that is DLC metalized thin film layer of $N_2$ plasma surface treatment are comprised. DLC thin film layers on Nickel surface are fragile. The results of the research indicate that the coefficient of friction on DLC metalized thin film layer is relatively low than Nickel surface and the durability of Nickel surface coated DLC metalized thin film layer is superior to Nickel surface. A relative evaluation of three form plate wetting properties using varnish liquid-drop plate indicates superior printing aptitudes for $N_2DLC$, DLC, Nichel plate order as above.

Since 2001, REITs are introduced in Korea as a type of general REITs and CR-REITs. But REITs are not succefully settled down in Korea. The purpose of the study is to propose the way to activate REITs in Korea. We should make up for the weak points in the current REITs system. For the success of REITs the followings are prepared.: first, REITs give a current, stable dividend income. second, disclosure obligations should be satisfied. third, securities are registered with the SEC are required to make regular SEC disclosures. fourth, REIT manager should be skilled, experienced real estate professionals. sixth, REITs must distribute more percent of its taxable income to its shareholders. seventh, Ownership interests be more flexible.

We develop an efficient numerical method for pricing the Derivative Linked Securities (DLS). The payoff structure of the hybrid DLS consists with a standard 2-Star step-down type ELS and the range accrual product which depends on the number of days in the coupon period that the index stay within the pre-determined range. We assume that the 2-dimensional Geometric Brownian Motion (GBM) as the model of two equities and a no-arbitrage interest model (One-factor Hull and White interest rate model) as a model for the interest rate. In this study, we employ the Monte Carlo simulation method with the Compute Unified Device Architecture (CUDA) parallel computing as the General Purpose computing on Graphic Processing Unit (GPGPU) technology for fast and efficient numerical valuation of DLS. Comparing the Monte Carlo method with single CPU computation or MPI implementation, the result of Monte Carlo simulation with CUDA parallel computing produces higher performance.

This paper focused on analyzing the effect against the Chinese Economy of Korea-China FTA and the trend of China-launching FTAs. And then this paper intended to deduce policy implications against the negotiations of Korea-China FTA. The points that Korea should consider in the process of the research and negotiations of Korea-China FTA are as follows: First, it is necessary that Korea should negotiate with China only in terms of the economic sector, excluding non-economic sectors which includes politics, national securities and so on. Second, Korea should put on the lists the every possible sectors that Korea has comparative advantages in. It is essential that the sectors include services in trade, TRIPs, ect. Third, the Korean government should put investment arrangements on the negotiating lists and ask China to afford a special favor to Korean investment In China. Forth, the Korean government should set the level of its tariff, considering the nation's trade deficit that Korea-China FTA will bing about.

It is essential for any public institution to establish a systematical scheme and a management system to maintain the contents and securities of its ever-expandingweb-site with efficiency. The general users want a reliable system and a simple and stress-free web environment, and expect the public institutions to maintain the accuracy and conformity of information they provide to the public. In かis study, 1 examined a web-site owned by a certain governmental research institute for the current maintenance status and problems to seek an effective and easy-to-use scheme for both users and web managers. Based on what I teamed from my study, 1 moved on to design a web integration system and tested it on the above mentioned web-site for analysis.

최근의 추세를 볼 때 위험관리에 관한 중요성이 점점 증대하고 있다. 그럼에도 불구하고 우리나라 은행들의 위험관리 실태는 아직 미흡한 실정이다. 그리고 대부분의 은행들이 현재 위험관리에 대응하기 위하여 ALM의 갭관리, 듀레이션관리 등을 행하고 있지만 BIS에서 중요시하고 있는 VaR의 개발과 운용은 아직 초보단계에 있다. 한국 주식포트폴리오에서 몬테카를로 시뮬레이션과 Full Variance Covariance Model의 VaR값은 비슷한 수준으로 Diagonal Model 의 VaR값 보다 작음을 알 수 있다. 이는 좀 더 정교한 계산이 요구되는 Full Variance Covariance Model의 VaR값이 보다 단순한 Diagonal Model의 VaR값 보다 정확성면에서 우수하다는 것을 보여주고 있다. 한편 이자율포트폴리오 의 경우에는 델타-감마 분석법과 몬테카를로 시뮬레이션의 경우 95% 신뢰구간의 VaR는 델타-감마 분석법이 작지만 99% 신뢰구간에서의 VaR는 몬테카를로 시뮬레이션방법이 작다는 것을 알 수 있다. 그래서 어느 한 가지 방법에 의한 VaR추정치가 가장 좋은 것이라고 단정하기 어려움을 알 수 있었다.

이 논문은 거시경제변수가 유럽, 호주, 한국의 주식시장 변동성에서 시간에 따른 변화(Time Variation)를 설명할 수 있는지에 관하여 조사하는데에 목적을 두고 있다. 그리고 이 논문은 미국에서 발표된 논문들의 결과와 달리 많은 경우에서 주식시장 변동성의 시간에 따른 변화가 과거의 화폐적 또는 실물적 거시경제 요소의 변화 가능성에서 통계적으로 유의하게 영향을 받는 지를 알 수 있었다. 따라서 자본 및 포트폴리오 배분에 대한 중요한 의미를 가지고 있다. 한국의 경우 경제회복에 따라 통화와 산업생산의 변동성 증가가 이뤄지면 주식시장의 성장에 중요한 역할을 할 수 있을 것이다. G7국가중에서 상대적으로 소규모국가인 이태리와 네덜란드에서도 위에서와 같은 결과들을 발견할 수 있었다. 한편 한국에서 특이한 점은 경제회복 이후에는 산업생산증가율의 증가가 통화량의 증가보다 더 주식시장에 중요한 영향을 줄 것임을 알 수 있다.
