수 처리 분야의 통합시스템을 구현함에 있어 이기종 장비 간의 데이터 연계는 프로그래머의 통신 프로그래밍 작업으로 매번 개발을 하여하는 문제점을 가지고 있다. 이로 인해 시스템의 안정화에 많은 시간 및 인력이 투입되고 있다. 본 연구는 인터프리터 엔진을 활용하여 엔지니어가 엔지니어링 한 데이터 (통신 스크립트)를 번역, 해석, 자동동작 시켜 별도의 프로그래밍 작업(개발)없이 엔지니어링으로만 통합 시스템의 감시 및 제어를 구축 가능케 프로토콜 편집기를 개발 하여 신뢰성 높은 시스템을 구축키 위한 내용이다.

As the cost of installing and maintaining software on large organizations such as recent companies and schools has increased, software installation and maintenance costs are low, system management is easy, demand for ease of use software solutions has increased. In the reality that special education for service center engineers is required along with the release of various products, training of the software and solution industry is regarded as important. Building Web-based user and system interactive environment, strengthened usability and educational ability effect suitable for engineer level. In the future, research that is familiar with specific software, not successfully combining multiple frameworks, rather than developers, will be increasingly important for research that can achieve optimal performance.

This paper proposes to apply machine learning to the process of predicting the slab thickness based on the structural analysis results or experience and subjectivity of engineers in the design of bridge data construction to enable digital-based decision-making. This study aims to build a reliable design environment by utilizing machine learning techniques to provide guide values to engineers in addition to structural analysis for slab thickness selection. Based on girder bridges, which account for the largest proportion of bridge data, a prediction model process for predicting slab thickness among superstructures was defined. Various machine learning models (Linear Regress, Decision Tree, Random Forest, and Muliti-layer Perceptron) were competed for each process to produce the prediction value for each process, and the optimal model was derived. Through this study, the applicability of machine learning techniques was confirmed in areas where slab thickness was predicted only through existing structural analysis, and an accuracy of 95.4% was also obtained. models can be utilized in a more reliable construction environment if the accuracy of the prediction model is improved by expanding the process

현재의 소프트웨어 개발 방법론은 소프트웨어 개발에만 국한 되어서 사용되지는 않고 있다. 도리어 인프라 시스템 구축방안에서 사용하는 것이 개발 방법론을 적용하는데 있어 더욱 정확하고, 인프라 시스템 요구분석 기술을 적용하는데 있어서도 개발 방법론이 부족하지 않다. 소프트웨어를 개발하는데 있어서 인도되는 시간을 프로젝트 초기에 산정하기가 매우 어려운 경우가 많지만 인프라 시스템 구축에서는 정확한 인도시간을 산정할 수 있다. 또한 소프트웨어 개발 프로젝트는 성공과 실패에 대한 기준을 설정하기가 모호한 경우가 많지만 인프라 시스템 프로젝트는 성공과 실패에 대한 명확한 기준을 설정 할 수가 있다. 하지만, 이러한 명확한 인프라시스템 구축에 있어 소프트웨어 개발 방법론을 적용시키는 경우는 거의 없다. 시스템 엔지니어의 시선으로는 소프트웨어 개발 방법론은 개발자만이 지켜야 하는 것이라는 생각이 크다. 이러한 문제를 해결하고, 인프라시스템 구축 방법에 소프트웨어 개발 방법론을 적용시켜서 표준화 하는 방법을 테스트 하였다.

Construction Projects have mutual collaborative structures among various participants for common objectives. Most of all the design project which is the initial phase in the project is crucial for determining project overall quality and requires intimate and continuous relations between project participants. Thus, this study suggests Design Collaboration Management System for successful performing projects through cooperation among participants in the initial stage of projects. First, expert interviews were performed to figure out present conditions of design collaboration management and problems. The factor analysis was applied to draw owner's collaboration factors and engineer's collaboration factors. Based on those factors, this study suggests design cooperation management process which gives a framework for systematic management method. Through the process the design collaboration management system was developed which helps owner/designers/engineer's co-work. The System suggested from this study realizes systematic information management tool and through that it is expected to improve design product;'s quality, and further contribute the advancement of project.

Traditionally engineers' main roles are concentrated on solving any given problems and engineering education has emphasized problem solving ability. Therefore engineers intend to solve easily perceived problems with their knowledge and experience instead of trying to analyze the given problems thoroughly and to define real problems, and go through lots of trial and error. So, engineers require the ability to define real problems accurately before trying to solve the problems. This study proposes a real problem definition process using visualization of a core zone and TRIZ concepts such as contradictions and IFR(Ideal Final Result) in order to define real problems with minimum trial and error. TRIZ is the theory of inventive problem solving and was developed by a Soviet engineer and researcher Genrich Altshuller from 1946. Nowadays many industries use TRIZ and its effectiveness was already proved by lots of real problem solving in various areas. Therefore TRIZ might be very effective tool for developing students' inventive thinking ability in engineering education.

To produce quality software products, engineers must feel personally responsible for the qualify of products. Superior products are not produced by mistake; engineers must strive to do quality work. Every engineer is different and has own process improvement method. To be most effective, engineers must plan their work and they must base their plans on their own personal data. To consistently improve their performance, engineers must personally use well-defined and measured processes. The Personal Software Process(PSP) is a self-improvement process designed to help software engineers control, manage, and improve the way they work. It is a structured framework of forms, guidelines, and procedures for developing software. Properly used, the PSP provides the historical data you need to better make and meet commitments and it makes the routine elements of your job more predictable and more efficient. Then, PSP is the very useful tool to train the students in Programming Language Course. This paper is to provide the concept of PSP/TSP and the sample curriculums for Program Language Training Courses. Personal Software Process(PSP) to train students of Programming Language Courses

Distillation columns are one of the main equipment used for the separation of chemical components in petrochemical process design. However, in spite of the efficient operation in wide range, and the advantage of data collection for equipment verification, the distillation columns are inherently known for high energy consumption and capital cost. Hence, the trade-off analysis needs to be done between investment cost and operation cost to develop the most economical distillation columns. This study was conducted using Aspen Plus, a popular process simulation program, in the pursuit of broad application by as many process engineers as possible. In this paper, design variables for optimization of distillation columns were defined to improve emphatically the design quality with reducing erratic practice of many engineers. In addition, by eliminating unnecessary reviewing step and establishing systematic and efficient procedures, the amount of time for design and human resources were minimized. Aspen Process Economic Analyzers (APEA) program was introduced in order to calculate the investment cost reliably, and the efficient systematic procedure for utilization of APEA was established.
