Many Applications of scientific research have coupled with functional data signal clustering techniques to discover novel characteristics that can be used for the diagnoses of several issues. In this article we present an interpretable multi-scale cluster hierarchy framework for clustering functional data using its multi-aspect frequency information. The suggested method focuses on how to effectively select transformed features/variables in unsupervised manner so that finally reduce the data dimension and achieve the multi-purposed clustering. Specially, we apply our suggested method to mutual fund returns and make superior-performing funds group based on different aspects such as global patterns, seasonal variations, levels of noise, and their combinations. To promise our method producing a quality cluster hierarchy, we give some empirical results under the simulation study and a set of real life data. This research will contribute to financial market analysis and flexibly fit to other research fields with clustering purposes.

Fisheries finance is divided into the policy time of long period of time and low interest and the special financing institutions, such as Fisheries Co-operatives. Union system finance is the system finance, which supports the fisheries system organization. Fisheries Co-operatives in cities, towns and villages are the independent management objects. Prefecture federation of Fisheries Co-operative is in prefecture stage. Norm Chukin Bank is in national stage. Each shares functions in these three stages, and finance is performed systematically, Fisheries policy finance comprises government financial institution capital such as the Agriculture, Forestry and Fishery Finance Corporation whish is based on the capital of a country or a prefecture financial fund, and fishery Modernization Capital used as financial funds through the government. Moreover, to complement such finance institutionally, Fisheries Credit Foundations, Agriculture and Fisheries Saving Insurance Corporation and National fisheries Co-operative Trust Enterprise Mutual Aid system have been established

The Port Development has been achieved by the Government because it needs large scale of funds. However, since 1994, the Govenment has been implemeting private investments for constructing and operating the ports and so on. Although the Government had high expectation that it could expedite the expansion of the port facilities, there were many problems in view of construction, management, financial and social environment. This study figure out that most of the important reasons are the uncertainty of risk allocation between private investors and the Government, using with Analytic Hierarchy Process. It is expected that the results of this study will encourage more private investors to participate in port private investments in the future.

Korean government has created the organizations for the private research development, has increased the support in taxes and funds, and has promoted the simplification of administrative structure and the removal of unnecessary restriction for the settlement of the private enterprise-centered technical reformation system. The investment of the research and development of Korea was 2.17% of GNP and the number of researchers was 89,000 in 1992. Korean government will expand the investment of research and development by 3-4% of GNP until 1998 and reinforce the number of researchers by 140,000. For the timely supply of the technical information, which is expected to be a major industry base in the year 2000, Korean government has already started to invest and continuously increased key projects which are focused on the database architectures, information distribution systems, and organizations for the information dissemination.

Tilting trains are now an established feature of railway operations throughout the world. For intercity traffic, tilt provides operators with increasing speeds, and therefore enhanced competitiveness, on existing routes where insufficient traffic or a lack of funds precludes the construction of a dedicated new high-speed railway. Appling the tilting train, we can expect 30% of speed up on existing lines, but the stability of the electric current would be low because of tilting the train. Also, the spark between the catenary and pantagraph cause environmental problems such as noise, radio wave malfunction. Therefore, the tilting on pantagraph for the power suppling device is very essential for stable electric power supply.

Small and Medium Enterprises(SME's) Informatization is the essential element for the competitive advantage. But SME's lack of IS specialist, Informatization Mind, IS implementation's funds etc. This study suggest Framework and Key Performance Indicator(KPI) which is will be able to diagnose a BPR & Information system of SME's Informatization and developed A Web-based Evaluation System for BPR & Information Systemsn(WESBI). WESBI help efficiently SME's Informatization implementation and WESBI' data which is accumulated provide guideline in the policy development a SME's Informatization.

Nowadays national research and development fund is continuously increased. And the evaluation on the feasibility of R&D budget investment was carried out. Through this study it was possible that a business feasibility evaluation of large scale research project. Also the benefit of research project about large scale plant(A plant) is $2.67{\sim}3.76$ times of research funds, and the R&D fund pay-back period is $6{\sim}8$ years. And also there is employment effect as $1,200{\sim}2,200$ every year, and $22,000{\sim}35,000$ within 20 years after research project.

The Ministry of the Energy and Resources is planning to invest a great deal of public funds in the energy conservation measures in order to conserve the energy. This study aims at applying the project scheduling model, especially to the energy conservation measures. In the study, we develop the project scheduling model, which is based on the modified Rorie-Savage problem. And the model is applied to the X-enterprise, which is one of the leading metal industry in the nation. The result shows that the model enables the top management to choose the set of projects which promises the largest profit among the entire projects. It appears that the proposed policy of the study is more profitable than the existing policy which is namely based on the qualitative consideration.

Nowadays, most of bridge networks are complete or close to completion. The biggest challenge railroad./highway agencies and departments of transportation face is the maintenance of these networks, keeping them safe and serviceable, with limited funds. To maintain the bridges effectively, there is an urgent need to predict their remaining life from a system reliability viewpoint. And, it is necessary to develop the maintenance models based on system reliability concept. In this paper, maintenance models are developed for preventive maintenance and essential maintenance by using system reliability and lifetime distributions. The proposed model is applied to an existing railroad bridge. The optimal maintenance strategy of this bridge is obtained in terms of services life extension and cumulative maintenance cost.

The concept of seismic design was induced in our country which was poor in it for the scarcity of recognition and insufficiency of funds. Recently many specialists are enforcing the provisions of seismic design. But because seismic force of seismic design is very great and all the seismic force are concentrated on the fixed bearings and substructure the bearings are the seismic force are concentrated on the fixed bearings and substructure the bearings are destroyed so that seismic design lose its basic concept. In addition when the earthquake which exceeds seismic design force takes place the bridge is collapsed. For these reasons the developed seismic isolation design concept was appeared which diminishes seismic force itself by period shift and additional damping distributes it to each superstructures evenly. Therefore this study introduced the method which combines PC-LEADeR(design program for L.R.B) with SAP 2000(linear elastic analysis) and performs the seismic isolation design more elaborately and simply verified the propriety of that method and examined the force control of L. R. B.
