This study is a research for an idea of costume containing clothing system in the early Practical Science School. The result are described as follows 1. Bak-Kyem, Han got a critical thought and attitude to seek for practical and rational as pect. Because that he studied an original text and wanted to find a basic meaning. And the result, he made a Pang-Ryeong Symeui. 2. Hwyeng-won, Rue contended that we had to model after chinese costume system to seek for a correct clothing system to harmonize with our culture and regulation. And he sought for the original courtesy because that his basic idea of reformation in the clothing system was an ancient system. But when there was a remedy, he suggested a new system. 3. Ik, lee considered a clothing system with a critical and investigated attitude. In the clothing system, he wanted to keep an original courtesy. But he asserted a constant reformation in evil tradition. He pursued a rationality not to be tied a formality, and he had also a flexibility to recognize real customs.

Database management systems are now used in almost every organization to maintain and utilize important collections of information. Relational DBMSs have a firm theoretical base. However, it lacks important features needed for representing certain critical aspects of an entity. One alternatives to remedy this problem is to adopt the object-oriented approach to the data model development process. In this paper, we tried to show the advantages of object-oriented data model design process for the development of extended relational database schema needed for the integrated plant information system at H. Heavy Industry Co.

It has been studied a lot to solve the problems concerning about the port management system in Korea. Since the international competitive power of port system in Korea is decreasing these days. This paper suggests that Port Authority should be given to the local government in order to not only properly meet the demands from worldwide change in port condition but also develop the major country which will lead distribution system of northeast Asia in 21th century. In this paper, I also acknowledge the following facts. 1. more power needed for local government to develop and manage port system 2. the harmony of port function and urban capacity needed in order to utilize the extending effect from port development.

Since a ductile coupled shear wall system is the primary seismic load resisting systems of many structures, a coupling beams of these system must exhibit excellent ductility and energy absorption capacity. In this paper, the seismic response of coupled shear wall system is discussed. It includes that the evaluation of the degree of coupling between the shear walls and the coupling beams. It is demonstrated through a review of experimental investigations of coupling beam behavior that often the coupling beam ductility demand exceeds the expected available ductility. As a result, it is possible that coupled shear wall system will not behave as desired in the course of a significant seismic event. Limits to the allowable degree of coupling are proposed as a remedy to this apparent deficiency.

최근에는 WTO의 다자주의 체제에 대비되어 지역주의 또는 양자주의를 표방하는 FTA의 체결이 급격히 증가하고 있다. FTA 체제하에서 무역구제제도는 존립 필요성 및 내용과 관련된 다양한 이슈를 가지고 있다. FTA체제 하에서 무역구제제도의 존립근거는 GATT 제24조에서 찾아 볼 수 있는데, 공식적인 무역구제제도는 반덤핑, 상계, 세이프가드가 있고 본 연구는 이러한 협의의 무역구제제도 개념에 국한하여 이루어졌다. FTA체결 시에는 한국의 경제상황과 국내산업 보호 필요성을 충분히 고려하고 FTA협상 상대국 별로 다른 무역구제제도를 도입하는 것이 필요하다. 현재, 한국의 기 체결된 FTA에서 무역구제제도는 대체로 WTO협정의 권리와 의무를 유지하고, 일부 FTA 무역구제분야에서 상황에 따라 협정의 일부를 변경하고 있다. 본 연구는 위의 분석결과를 실제 한 중 FTA의 무역구제 협상에 적용하였는데 즉, 중국과의 산업전반 및 주요 교역품목에 관한 경쟁력 우열관계를 고려하여 무역구제제도가 결정되어야 할 것이다. 따라서 FTA의 체결 목적을 충분히 고려하고, 예상치 못한 경제상황 변화에 대비한다는 취지에서 무역구제조치의 발동 근거를 마련할 필요가 있다. 또한 민감품목에 대해서는 추가로 특별세이프가드 규정을 도입해야할 것으로 생각된다.

Worldwide, air transport demand of this century is expanding rapidly, and each countries' demand is also increasing. Thus a number of low-cost carriers emerged in existing air transportation business sector and airman qualification check work regarding aviation safety management is increasing too. As the remedy for the result of aviation safety audit by ICAO and FAA in 2001 that governmental activity for aviation safety had been performed by a small number of aviation safety inspectors, airman qualification inspection system implemented by airlines was improved and the government has established the system that authorized airman qualification inspectors check airmen qualification with airlines according to the international trend. This study suggests the need of improvement of airman qualification inspection system that existing inspection system as the means of safety management can be transferred to Operations Safety Inspection(OSI) activity which is compliant with international standards.

Electromagnetic levitation system(EMLS) is one of the well known nonlinear systems due to its high degree of nonlinearities. Moreover, when there are uncertain parameters in EMLS, it is not easy to have an accurate control of EMLS. In this paper, we first apply a standard input-output feedback linearzing controller to EMLS and investigate the possible control error caused by uncertain coil resistor. Then, as a remedy, we design and apply a robust controller using Lyapunov redesign technique to deal with this uncertain coil resistor in the system. The validity of our robust controller is verified via system analysis and experimental results.

In this paper, we propose a novel OFDM-based system structure to reduce PAPR (Peak-to-Average Power Ratio) and improve BER for OFDM system in which BER enhancement is obtainable based on WH (Walsh-Hadamard) transform to transmit concurrently each data symbol on all subcarriers so as to take advantage of frequency diversity and remedy the effect of channel's frequency-selectivity. By doing so, we also attain a low PAPR. Moreover, DGT (Data Grouping Technique) that is independent on the side information is also applied to further reduce PAPR. The simulation programs have been also performed to verify the validity of the proposed system.
