Component based design is perceived as a key technology for developing advanced real-time systems in a both cost- and time effective manner. Already today, component based design is seen to increase software productivity, by reducing the amount of effort needed to update and maintain systems, by packaging solutions for re-use, and easing distribution. Nowdays, a thousand and one companies in If(Information Technology) industry such as Sl(System Integration) and software development companies, regardless of scale of their projects, has spent their time and endeavor on developing reusable business logic. The component software is the outcome of software developers effort on overcoming this problem; the component software is the way propositioned for quick and easy implementation of software. In addition, there has been lots of investment on researching and developing the software development methodology and leading If companies has released new standard technologies to help with component development. For instance, COM(Component Object Model) and DCOM(Distribute COM) technology of Microsoft and EJB(Enterprise Java Beans) technology of Sun Microsystems has turned up. Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, It suggest that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. about implements and accomplishes the modeling for the Product Control component development by applying CCD(Contract-Collaboration Diagram), one of component development methodology, to MRP(Material Requirement Planning) System

A company wishes to obtain a competitive edge by adopting an efficient logistics information system to control the logistics management process. The elements of the competitive edges a company targets are to maintain good quality, reduce cost and on-time delivery and those competitive edges are closely related to the cycle time of a product. The logistics information system in a company is also closely tied with other business activities than the logistics itself. Therefore it is essential to choose a system that will help rationalize the logistics but also overall business operations along the supply chain from manufacturing to distribution of the products. This paper aims to research and analyze a problem with a logistics information system through case study and to suggest a logistics information system with RFID in place adopted to eliminate problems such as damages, loss and defect rates.

The purpose of the present study was to examine the effectiveness of an English program called Global English. The fall, 2003, program at a 4-year university in southwest Korea, was designed for students to attain ability and confidence in both oral and written reports in English necessary to participate actively in everyday and business situations. The study described the educational principles and curriculum in detail and provided an overall evaluation of the program. Students' communicative competence was measured by the computer-based TOEIC both prior to and in the middle of the Global English instruction. Questionnaires were administered to 2,791 students and to 18 native English-speaking teachers to identify their satisfaction with the program. The results from the paired-samples t test indicated that the Global English program significantly affected students' English achievement scores. The students demonstrated satisfaction with the program in the analyses of the questionnaires: The students' motivation, interest, and attitudes towards learning English improved, and their anxiety in speaking English with native speakers was lowered; their confidence increased. On the basis of the findings, educational suggestions were made for improving the Global English program.

철골 중심가새골조의 경우 접합비용의 절감을 위해 가새가 설치된 스팬을 제외한 기둥들은 통상 중력기둥으로 설계된다. 따라서 중력기둥이 미치는 P-{\Delta} 효과를 내진성능 평가에 적절히 반영할 필요가 있다. 본 연구에서는 철골 중심가새골조의 중력기둥이 유발하는 P-{\Delta} 효과를 가상의 의지기둥(leaning column) 개념에 의해 간편하게 모델링할 수 있는 해석기법을 예시하였다. 역V형 가새골조를 사례로 하여 FEMA 273의 비선형정적해석법에 의한 내진성능평가를 수행하고 동적 P-Δ 증폭계수 적용에 있어서의 문제점을 지적하였다. 본 연구의 결과에 의할 때 P-{\Delta} 효과는 중심가새골조의 내진성능평가에 무시할 수 없는 영향이 있는 것으로 밝혀졌다. 아울러 기존연구에서 제시된 인장보강재에 의한 역V형 가새골조의 보강법은 내진성능향상에 매우 효과적임을 확인하였다.

Is not used by consistency transport at transport of freight nothing but is using Pallet only by pedestal when work palletized unit load or materials handling when keep simplicity receptacle which fill raw material or product in factory in our country. Therefore, pallet that is most important function of Pallet is not empled circulation to end consumer from manufacturing plant which is circulation process whole path being done and factory. It is real condition stopping only in extremely determinate part process use of warehouse back. Additionally, it is possible to figure out the flow of all the materials loaded on the RFID pallet; product, material, raw material immediately, so that epoch-making management is possible and it contributes to the reduction of logistics cost because there are little loss or outflow of pallet. The materials flow is getting speedy and inventory is decreasing in the logistics process, and also bad inventory and loss problems are prevented. As a result, not only logistics cost of company but also national logistics cost is decreased. Thus it contributes to the strength of national competitiveness.

In U.S.A., minimum wage of New Jersey in April 1, 1992 rose from $4.25 to $5.05. At this assession, there was survey by 410 numbers related back and pro minimum wage in New Jersey and eastern Pennsylvania.. At stores of New Jersey and eastern Pennsylvania, comparison of the increase of employment at constant minimum wag is with estimative effect of increase of minimum wage. Through comparison of stores of low wage and high wage above $5, employment volatility in New Jersey was studied. In U.S.A., increase of minimum wage was not caused to reduce to employment. Contrary to this, result of Korea was not consisted after timing of IMF bailout of 1997. It is because drop of revenue was caused to decrease employees of part-time and full-time job at the viewpoint of cost minimization.

서해 상에서 저기압과 태풍 통과 시 해상상태를 비교 분석을 하였다. 1999년 4월 9일∼12일에 강한 저기압이 화중지방에서 발생하여 서해를 지나 한반도에 영향을 미친 경우의 9905호 태풍 NEIL과 9907호 태풍 OLGA가 서해를 통과하면서 서해 연안에 영향을 미친 사례이다. 봄철 이동성 저기압 발생 시 에는 저기압 중심부의 풍속이 주변 지역에 비해 위상이 빠르고 강하게 나타나며, 이에 수반되어 발생하는 파고는 주변의 지형적 영향으로 다르게 나타날 수 있다. 이에 비해 두 태풍에 의해 발생한 파고는 태풍 Olga가 서해 남부해역에서 북상할 시기에 칠발도 근해상에서 5m이상의 높은 유의파고를 발생한 것 이외에는 저기압 통과 시보다 파고가 낮다. 해일도 태풍보다 저기압 통과 시에 더 크게 나타나는데, 이러한 결과는 강하지만 국지적이고 빠르게 이동하는 태풍보다 종관적이고 느리게 이동하는 기압장에 의해 발생한 파도와 해일이 더 클 수 있음을 보여준다.

본 연구는 2000년 일부 구간이 자연형 하천으로 복원된 불광천을 대상으로 하여 한 하천 내에 정비방식이 다른 직강화 하천구간과 자연형 하천복원구간으로 구분하여 식물상 및 식물종의 출현빈도를 비교 분석하였다. 조사는 2003년 5월과 8-9월에 걸쳐 이루어졌으며, 식물상은 하천의 양안에 출현한 모든 식물을 동정하여 정리하였고. 식생은 200m를 기준으로 하여 Belt-transect 방법을 이용하였다. 2003년 5월 및 8-9월은 직강화 하천구간에서는 33과 73속 88종의 식물이 출현하였고. 자연형 하천복원구간은 36과 76속 90종의 식물이 출현하였다. 귀화율 (Naturalized Index：Nl)은 직강화 하천구간은 22.7%, 자연형 하천복원구간은 21.1%였고, 도시화지수 (Urbanization Index：Ul)는 직강화 하천구간이 7.8%. 자연형 하천복원구간이 74%로 직강화 하천구간이 자연형 하천복원구간보다 약간 높았다. Belt-transect 조사법에 의한 식물종 출현빈도 결과는 직강화 하천구간에서는 하안에는 여뀌와 환삼덩굴이 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 이에 반해 자연형 하천복원구간에서는 하안에는 갯버들, 여뀌, 소리쟁이. 환삼덩굴이, 제방에는 망초와 큰비짜루국화가 가장 높은 출현빈도를 보였다. 즉 직강화 하천구간과 자연형 하천복원 구간은 제방에는 구간에 따른 차이가 없고, 하안의 경우에는 자연형 하천복원구간에 도입된 갯버들이 출현하여 차별을 보였다.
