In this study, an overall survey of ERP system and methodology are first introduced, then an efficient way of const겨cting ERP system is suggested through a case study on S company S company has not reached the goal of ERP system as it planned and is still working on the project. The main idea for the efficient construction methodology of ERP system is that BPR (Business Process Reengineering) should be accomplished and the company should have enough time to test the ERP package and a proper ERP team organization before the ERP system is introduced. It is suggested that introduction of ERP system bring about benefits to companies in terms of effective management system.

우리나라 도로중 PMS가 구축된 도로는 현재, 고속도로와 국도가 있다. 그러나 많은 시(市)에서 도로의 효율적인 관리를 위해 요구되는 시도로 PMS는 아직 없는 실정이다. 따라서, 본 논문에서는 시단위에 적용가능한 Prototype PMS 전산시스템을 개발 제시하였다. 개발한 PMS는 기본적으로 PC 수준에서 운영 가능하도록 구성하였으며 GIS 기능을 이용하여 사용자가 쉽게 포장상태나 유지보수 현황 및 계획을 이해할 수 있게 하였다. 본 PMS의 기능상 구성은 크게 조회, 분석, 자료관리, 출력 부분으로 구축하였다. 특히, 분석과정의 주논리(보수우선순위결정, 보수공법결정)부분은 필요시 사용자가 각 항목의 criteria 값을 수정 할 수 있게 하여 시스템운영이 경직되지 않도록 배려하였다. PMS 데이터베이스의 항목은 시도로 PMS의 규모 및 목적을 고려하여 선정하였다. 또한 PMS에서 사용된 도로 관리길이 및 위치 지정체계는 노선을 기준으로 기본 100m길이의 section으로 분할관리하였으며, 위치 지정체계 방식은 reference points 방식을 기본으로 사용하였다.

조절 부족 환자와 조절 용이성 부족 환자에 대한 사례 연구를 통해 실제 엄상 결 과를 비교하고， 각각의 치료 방법과 그에 따른 효과를 확인하였다. 본 임상 연구는 진단을 내리기 위한， 각각의 특성 및 임상 결과 평가에 초점을 두었으며， 두 사례간 꾀 다른 접근 처방 방식과 그에 따라 환자의 기능 시스템에 미치는 긍정적 효과에 대해 고찰해 보았다.

Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. For this reason, this study is to build up the users demand for the imminent marketing product of a certain company by Analytic Hierarchy Process, analyze quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of Quality Function Deployment. And, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for the correlation users demand with technology and for the processing and marketing of a new product. The all assumption on this thesis was based on the reliable real data of a certain company.

This study proposes strategical, practical guide to build up ERP system through several case studies to large company and comparative analysis of success and fail factors. Key words in paper .is in summary of previous BPR and ERP studies, try to clarify relationship between BPR and ERP, derivative seeking of practical key success factors through several real cases studies to build up ERP system which is in-house development or customization of commercial package.

A field case study was performed to investigate the effect of shallow ponding in paddy field on irrigation water requirement of direct seeded rice. In addition, an economic analysis was made to see the effect of no-till direct seeded rice on cost reduction. A field study was performed at a 2.1ha paddy field in Kimjae city, Chonbuk province from 1991 to 1999. Various direct seeding methods such as dryland seeding, wetland seeding, and no-till wetland seeding were introduced. Then, cost reductions due to the direct seeding and no-till were calculated. In addition, to investigate the effect of shallow ponding on irrigation water requirement, field measurements such as irrigation water volume, drainage water volume, rainfall depth, and ponding depth, were made at a 40a plot within the same area in 1988 and 1990. The results of the shallow ponding study showed that the irrigation water depth, rainfall, and the drainage depth were 379mm, 458mm, and 448mm in 1988 growing season, and 274mm, 819mm, and 736mm in 1990, respectively. The shallow ponding irrigation method saved irrigation water by about 20% with higher yield compared with the traditional method. The economic analysis showed that won \640,000 per ha can be saved by direct seeding due to no nursery cost, and \1,220,000 per ha due to no-till and no nursery cost. The yields ranged 540 to 640 kg per 10a during the study period with an average of 590kg per 10a. If these cropping techniques with no-till direct seeding and shallow ponding depth for rice cropping prove to be advantageous with further study, they can be adopted for the most of the paddy fields in Korea.
