디스플레이 산업은 현재 세계 최고 수준의 LCD 및 PDP 양산 기술을 보유하고 있으나, 우리나라의 정보 디스플레이산업을 10년 내에 10% 수준으로 높이기 위한 노력이 양산기술 개발뿐 만 아니라 핵심 부품재료 및 원천기술 개발도 병행되어야 한다. 2010년에는 1,00억 달러 이상의 세계 시장이 예측되므로 기존의 LCD 및 PDP 뿐만 아니라, 앞으로 산업화가 가능한 디스플레이 제품의 핵심이 되는 기술 개발에 많은 노력이 요구된다. 디스플레이 용도별 전망을 요약하면 고화질(HD) TV에서는 PDP, TFT-LCD, FED 및 Rear-projection TV의 경쟁이 예상되고, 여기에 유기 EL이 가세할 전망이다. 단기적으로는 PDP가, 중기적으로는 TFT-LCD가, 장기적으로는 유기 EL과 FED가 유망할 전망이다. 모니터와 노트북 분야에서는 TFT-LCD가 주축을 이를 것이며, 유기 EL이 가세할 전망이다. 또한, 차세대 디스플레이 기술인 종이처럼 얇고, 필요할 때 펼쳐볼 수 있는 flexible display는 영화 속의 상상만이 아니라 가까운 장래에 실현 가능하며 유기 EL 디스플레이, 유기 TFT 및 전자종이 기술이 이와 같은 꿈을 실현시켜 줄 것이다. 디스플레이의 주생산국으로 현재는 일본, 한국 및 대만에 한정되어 있으나, 10년 이내에 중국이 가장 강력한 생산국가가 될 전망이다. 따라서 우리나라가 중국과 경쟁에서 우위를 확보할 수 있는 전략을 세워야 될 것으로 믿는다. 디스플레이는 정보 산업의 핵심 부품이며 반도체와 더불어 우리나라의 주력 수출산업이며, 기존 시장의 지속적인 성장뿐만 아니라 디지털 컨버전스 추세에 따라 신규 시장이 개척되는 미래 유망 산업이다. 따라서 디스플레이산업은 이미 세계 수준의 반도체, 이동통신, 인터넷 기술 및 가전 기술 등의 분야에서 국가경제 성장엔진으로 중요성을 인정받고 있으며 세계 시장에서 경쟁력을 갖추고 있는 분야이다. 그러나 우리나라는 미국, 일본 및 유럽연합 등 선진국뿐만 아니라 중국 등 신흥공업국의 도전에 직면해 있으므로 디스플레이산업이 지속적으로 발전하기 위해서는 나노-정보 기술(NT-IT) 등 첨단 기술과의 융합을 통한 신기술 개발과 신시장 개척에 주력해야 한다.

Further more, despite of much development and investment for water resource which caused by increasing the social and economic expectation of water resource, the problem is getting worse and seems impossible to solve because of the complexity, variety and acuteness. To make matters worse, government almost do not give countermeasure for the small water supply systems which supply safe water for the rural residents neglected from government. The target region, named H-Gun, is an area of 983.38 ㎢ and has a population of 56,000 and 141 industries. It is a typical farming village. Based on the result of the 1st and 2nd quality inspection of underground water for the simplified water supply system of 17 areas 503 points in 2004 and 2005, this study compare and analyze the 4 areas 20 points and around that has often been founded as undrinkable water. Also it presents what is the result of that and how the result affect the surrounding underground water. Looking into the geological condition of H-Gun, underground condition is base on granite surrounded metamorphic sedimentary rock segment, the content of turbidity, hardness, remains of evaporation, fluorine is higher, during the season of not much using water from early winter to early spring the deterioration of water quality does not appear but from spring to early summer, because of incoming many impurities caused by much using water, serious deterioration of water quality showed up, neighboring underground water appeared the same case. In the part of environmental effects, there were lots of small water supply systems surrounded by farms, during spring because of using many agricultural chemicals, fertilizers, composts, the range of water quality fluctuation increased, neighboring underground water showed similar tends too.

This study attempted that determine the way to reduce the negative pressure effectively in pipeline by a test and computational water hammer analysis when water hammer occurs. An air valve can make negative pressure reduced by inhaling atmosphere, but an air valve has the delay time caused by the buoyancy in air valve. Besides, an air valve can be potential risk factor because of mechanical defects like fixation of float in the air valve body. To solve problems of air valve, “Prevention Equipment for negative pressure” is recently invented that can inhale atmosphere forcibly by sensing the pressure and level in air valve when water hammer occurs. However, there has been little application of the equipment because effects of the equipment hasn’t been proved yet. This study attempted to prove the effects of the prevention equipment by conducting a performance test. As the result of test, it was determined that installment of the equipment can reduce the operation time of air valve. In addition, a water hammer computational analysis was conducted based on the result of test. As the subject of computational analysis, two practical pump-pipeline system were selected which have different characteristic. As the result of analysis, it was founded that installment of the equipment can relieve negative pressure quickly in pipeline. So the capacity of air chamber can be also reduced. In addition, it was also determined that the effect of prevention equipment is even lager in the flat pipeline with a long pipe length and low actual pump head. On the other hand, the effect of prevention equipment is not significant in the steep pipeline with a short pipe length and high actual pump head. In the future, it is expected that the construction period and cost of water and sewage facility can be reduced by using this study and install the prevention equipment for negative pressure. Besides, the stability of operating facilities can be also improved.

Axially moving beams often exhibit lateral vibration. This thesis presents a result of dynamic analysis and vibration suppression for axially deploying beams. Two modeling approaches are introduced: modal modeling method and finite element method. Simulations are made to validate the proposed modeling methods as well as to investigate the dynamics of axially deploying beams. Unlike other models, the proposed models include gravity as a source of vibration. In order to suppress lateral vibration for deploying beams, the moving speed command is modified by using input shaping method. Experiments are also performed to prove the proposed vibration suppression method. The simulations and experiments show that the proposed modeling and input shaping methods are effective for the dynamic analysis and vibration suppression of axially deploying beams.

As financial sector becomes liberalized and universalized, a tight control on its asset quality also becomes a visible trend over the world. Financial authorities urge banks to prepare the sufficient rules, regulations and constraints in order to maintain better asset quality and hold stability and credibility. The authorities will guarantee banks freedom of management in exchange of acceptance of their supervision The ways to regulate banks varies according to each country's conditions and financial profiles. However, the core regulation is same to all in that every bank should reserve its capital proportionate to risk assets holding. And, the capital ratio is universal under the common standard set by The Bank for International Settlements (BIS). The purpose of regulating capital ratio is to protect banks from bankruptcy by absorbing difficulties in management with the proper capital reservation. A supervisory authority is given its power to regulate financial institutions from consensus that supervisory organization will execute a helpful function before financial chaos and malfunction of financial system. The Basel Committee of the Bank for International Settlements made the New BIS Capital (New Accord) Standard, in June, 1996, which will set to raise risk sensitivity of BIS Capital System. And also, it increases individual bank's discrepancy in risk measurement. Basel Committee approved the New Accord and decided major member banks of the Committee to apply the Accord from year 2006. Since Korea accepts applying the New Accord to all Banks in 2007, Korean Banks start to prepare the application. In this paper, I summarize theoretical basis for BIS Capital regulations and core content of the New Accord, major disputing issues and possible effects by the new BIS standard application. In addition to the summaries, I search to develop the solution for the New Accord application and to plan for efficient shareholder's equity management in small & medium size banks. The New Accord consists of 3 Pillars. Pillar Ⅰ, the minimum capital regulation, tells that banks should reserve over 8% capital of total risk-weighted assets including operational risk as well as the previous credit & market risks. Especially though a bank can choose the Standard Measurement or Internal Ratings Measurements according to the level of bank's credit risk management, the classification of debtor's credit risk is more diversified than the previous one. Pillar Ⅱ, regulative authority's supervision, requires that the authority is given to inspect and measure capital adequacy and risk control procedures. When needed, the authority will take a proper action for reducing possible side effects. Pillar Ⅲ, market regulation, mandates that a bank should disclose information about risk level and capital adequacy in the market. Major disputing issues from application of the New Accord are that too complicated regulations, construction cost for measurement system, incompatibility to a business cycle, "expanding loans in boom but projecting loans in depressions", different internal measurement systems for different banks, operational risk not cured by capital reservation. The effects for the application of the New BIS pillars are that few banks with better risk management capability will have more favorable market and client. Those banks will focus more on small loans & collateralized mortgage due to better manipulations of credit risk, provisions and preference on safe assets. Bank will tighten internal control after introduction of operational risk. When the New Accord is introduced, we expect the introduction to improve domestic bank's risk management capability and concrete bank's stability and financial system by reserving proper level of shareholder's equity in the long term. But, many also worry that the introduction will result in enlarging width of business cycles, raising funding cost, preferring highly rated safe assets and projection of issuing asset-backed securities. When we adopt the New Accord, we have to build stable growth base by maximizing positive effects and minimizing negative effects. So, I mention several suggestions in this paper to maintain proper capital and to keep in mind must-knows of the Accord in respect of small and medium size banks. First, small and medium size banks should adapt an advanced risk management system since risk management is all about banking. We need to develop and practice software of risk management in addition to development of hardware. Considering Small and Mid size bank's risk preference and characteristics, they should maintain appropriate capital level, prepare possible risk crisis. The banks reduce fluctuation of necessary capital and introduce dynamic provision system by formulating risk management policies and strategies. Preparing the time when BIS capital falls below the guided level by the regulative authority, a bank should have an ability to issue new shares or bond with warrant. If both are not possible, a bank must execute to raise BIS ratio by downsizing its risk assets, selling off loans or issue asset-backed securities. Second, when a bank introduces the New Accord, it will equip sufficient data accumulation and system. Considering the size of the banks, it is highly possible that the Accord introduction in second half of 2007 would rouse inevitable errors and cost spending. For adopting IRB measurement, we need to obtain consistent loan data. In order to get the consistency, a bank should upgrade loan procedures and consolidate various systems. Since those infrastructures are inferior to big ones, they should be considered to apply the same standard measurement. When small banks obtain enough data and competitive system, it is natural that they then set forward to the IRB measurement. Third, since the New Accord will affect credit ratings, internal performance evaluation, portfolio strategies, loan decision-making, internal control, risk management, etc., we do not mistake to think that the Accord is merely a capital regulation. An application of the New Accord gives banks an opportunity to keep pace with the global standard for innovating primary infrastructures. Especially, small and middle banks will have an opportunity to accustom the advanced banking management and business culture for them, which are lack of well-educated practitioners and advanced system. They should also try hard to be competitive in adopting the new global standard. Forth, small and middle banks have to reorganize themselves and allocate proper human resources to the new BIS related works. Since the application of the New Accord may greatly affect bank's infrastructure, managements should stand in the center of all workers with long-term blueprint. The application is not few teams job. In order to be competitive to a peer group, a bank should be customized and upgrade a developed system. For doing this, a bank should focus on obtaining risk professionals as well as development of system. Fifth, a bank should receive reliable credit ratings. The core of the New Accord is to measure necessary capital under IRB measurement. To measure it, a bank needs to settle internal rating system and maintain consistency and stability of ratings. Though a bank can keep the consistency for scoring, bank cannot maintain the consistency all the time. There may be data problems, drastic change of business environment, inexact measurements. I suggest that small and medium size banks mainly use qualitative analysis with support of quantitative analysis for keeping the consistency and stability.
