The minimum attractive rate of return (MARR) has been used for many years as a decision criterion in engineering economic analysis. Typically, inflation has been either ignored in such studies or considered by adjusting each of the individual cash flows associated with a project for inflation, frequently a lengthy process. This research investigates a new decision criterion for economic analysis, the comparative rate of return (CRR). The CRR is defined to be the minimum rate of return earned on uninflated cash flows of proposed expenditures is simplified, since the analysis can be performed on the uninflated cash flows. The research presents a derivation of the CRR and investigates its relationships to the MARR, inflation rate project cash flows and project life.

kEPCO is now conducting a project called the "Feasibility Study & Basic Designs for the 500kV Transmission System in Myanmar" as its second overseas project following the "Development Study on the rover System Network Analysis in Myanmar" performed from 2001 to 2002. As a part of this project, this paper deals with the analysis process and results of the demand forecasts, master plan for transmission system expansion, and the major factors for the new 500kV transmission facilities.

In this study, the productivity factors of software maintenance are categorized into the three areas such as maintainer characteristics, software technical characteristics and maintenance environment characteristics. And the various regression analyses are performed for searching the most significant model by using actual project's data. At conclusion, an linear model including new variables derived from factor analysis to estimate the effort for software maintenance project is suggested.

ECDIS, highlihgted as a new technology for the navigation safety, could replace the paper charts in the bridge and make the more safe navigation possible. For the marines to use the ECDIS, the infrastructrue of the ENC production and distribution, the development of IMO compliant ECDIS, the training program for the ECDIS usage and related matters are thought as the key points to be solved. Also it is necessary for the ECDIS usage and related maters are thought as the key point to be solved. Also it is necessary for the related groups, such as ECDIS manufactures, users, ENC producers, the to be involved in developing the national infrastructure altogether to promote the ECDIS usage. Upon these background, the Korean ENC pilot project was introduced and the comparison study of the SHARED project coordinated by MPA(Maritime Port Authority, Singapore) and the Canadan Pilot project has been done. With such a analysis, the Korean ENC sea trial test plan is presented.

The purpose of this study is to define the role of a T. Q. C. engineer in the plant engineering activities. A "plant engineering" moves to complete a new project through a series of stages such as: 1. Research & Development stage. 2. Economic evaluation & engineering design stage. 3. Erection & start up stage. 4. Final production & control stage. This suggests that the plant engineering project should be carried out with a wide variety of tasks, as well as a central control. For a successful completion of the project, a T. Q. C. engineer is required, in practice, either as a central activity creator or as a key advisor in each task.

In 1980s, studies on the river environment and the management techniques to maintain the quality of water achieved actively. From the beginning of 1990s, the concept considering the river ecology and conservation in urban area have been introduced in Korea. Recently, some environment friendly projects on the rivers have been executed and some are under way. Many small rivers in rural areas have been maintained considering landscape and partly ecology. However until the pilot project named Songsam drainage channel project started in 1998, there were no studies and projects on the irrigation and drainage channels considering environment friendly maintenance. Korea Agricultural and Rural Infrastructure Corporation (KARICO) is going to introduce environment friendly and naturally favorable maintenance technique when the new projects to reform the irrigation and drainage channels are planned. Irrigation channel in O-dong project site in Yeomsan-myeon, Younggwang-gun was designed considering environment friendly consolidation and maintenance.

In this study, we propose an expert system aided model necessary for extracting the rules, which can diagnose the success level of new product development project. For this purpose, first, we design a classification model to analyze the characteristics of $\ulcorner$parts development projects$\lrcorner$. Second, in order to select success factors, we explore literatures and interview with project managers working at large sized companies of electronic parts. And we conduct the enquete survey and statistical analysis to extract key success factors. Third, in order to decide the level of project success, we use the concept of 'Recearchitivity' as a framework of judgement criteria. Fourth, in order to extract diagnosis rules, we use expert system development tool.

BOLERO project and TradeCard System are attracted public attention as new settlement method that is able to substitute for documentary letter of credit. BOLERO is the business processes and methods, together with the digital information system, which are provided by Bolero International for communicating Messages and Documents and facilitating business transactions. TradeCard aim to make international business-to-business e-Commerce easy, fast, inexpensive and secure while innovating current documentary compliance and financial settlement mechanisms. The main purpose of this paper is to search the possibility of paperless trade. Since, this paper examine the international legal feasibility of these systems and compare the strength and weakness.

Recently, many enterprises wish to preoccupy competitive positions in the market by motivating themselves towards CALS(Commerce At Light Speed) and try hard to achieve system implementation with the use of new concept-based backbone systems such as ERP(Enterprise Resource Planning) or PDM(Product Data Management). However, unfortunately there is an inevitable discrepancy during implementation period between package vendors and customers due to lack of clear methodology and misunderstanding about system. In some cases, consensus on partially verified system design invokes customers'continuous change demands and often it tends to result in unnecessary project delays. PDM application system implementation project of the company L has been studied here to solve these sorts of problems. The major yields of this work are achievement of a willing approval from customers and rapid system design under a time-limited and conceptually defined project scope and finally, through fully verified system design, we were able to reach successful system implementation.

The development of station districts is mainly categorized into 4 types. The first one is the composite development of the railroad station-areas. The second is the re-development of the direct station districts. The third is the rearrangement of the indirect station districts. And the fourth is the development of the new station districts for newly constructed railroad routes. Among these, this study aims to focus on the problems and methods of improvement in the development of the railroad station-areas, since there is not much problem with the implementation of the city development project, housing site development project or city rearrangement project for the direct or indirect station districts.
