플라즈마를 이용한 건식식각공정은 현 반도체, 디스플레이, 태양광 산업에 널리 적용되는 공정으로며 일부공정은 플라즈마 없이는 식각공정이 불가능할 정도로 매우 중요한 공정이다. 건식식각공정은 크게 플라즈마의 이온에 의한 물리적인 프로세스와 라디칼에 의한 화학적인 프로세스로 나눌 수 있으며, 최근 들어, 화학적인 식각프로세스가 매우 중요함이 알려지게 되었다. 본 발표에서는 화학적 식각프로세스에서 가장 중요한 역할을 하는 플라즈마 라디칼을 챔버가 공정에 제한받지 않고 널리 쓰일 수 있는 데이터 베이스로 생산하는 아이디어 전략을 소개하는 시간을 통해 건식식각물성데이터 센터의 소개와 참조표준 데이터베이스의 중요성을 알리고자 한다.

All of the partner must manage continually scheduling for the successful project in construction. Besides, that is not a important only contracter's managing but also owner's managing which is a very important about project finishing in time. Especially, in the case of mega project, the owner has to manage progress of scheduling to control contractor. And the case of progress to delay or to change, owner, contractor, and inspector must make a plan of recovery scheduling. This study proposes a construction process model from IDEF Methodology.

Big data is an emerging issue as large data which was impossible to be processed in the past is possible to be handled with the development of information and communication technology. Manufacturing is the most promising field that big data is applied such that there are abundant data available. It is important to improve an efficiency of manufacturing process for quality control and production efficiency because the processes from production design, sales, productions and so on are mixed intricately. This study proposes big data cloud service for manufacturing analysis using a big data technology and a process mining technique. It is expected for manufacturing corporations to improve a manufacturing process and reduced the cost by applying the proposed service. The service provides various analyses including manufacturing analysis and manufacturing duration analysis. Big data cloud service has been implemented and it has been validated by conducting a case study.

소프트웨어 시스템에 대한 요구사항이 증가하고 그 규모가 점차 거대.복잡해짐에 따라 시스템을 개발하기 위한 절차, 방법 등이 무수히 생겨나게 되었다. ISO/IEC 12207 소프트웨어 생명주기 공정 표준은, 존재하고 있는 소프트웨어 개발 및 유지보수에 대한 절차 및 방법에 대한 일반적인 지침을 제시하고, 이전의 프로세스 공정 표준들이 적용될 수 없는 새로운 개발 패러다임을 지원하기 위해 제정되었다. 이 표준은 표준 자체의 특성의 하나인 보편성을 유지하기 위해, 특정 프로세스 모델에 치우치지 않는 기반 표준(Base Standard)의 성격을 갖는다. 결국 기반표준은, 어떠한 프로젝트에서 어떠한 프로세스 모델을 사용하건, 임의의 방법론을 사용하든 모든 경우에 적용될 수 있어야 한다. 최근, 질적인 성장 뿐 아니라 양적으로도 풍부한 성장을 거둔 객체지향 개발 환경에서는 전통적인 개발 환경에서와 많은 차이점을 보이며, 새로운 개발 프로세스들을 제안하고 있다. 본 논문에서는 객체지향 개발 프로세스 중 현재 가장 대중적으로 사용되고 있는 Rational사의 Unified Process를 선택하여 ISO/IEC 12207 표준의 적용성을 고찰해보고, 표준의 발전, 개선방향에 대해 모색해 보겠다.

This paper describes a case study on an enterprise ontology(30) based analysis and representation of the production operation in shipbuilding. The production operation consists of steel fabrication, assembly, election, launching, sea trial and delivery process. We represent and analyze the steel fabrication process and the piping design business of the assembly process among them. First, we build an ontology on concepts of steel fabrication process and the piping design business of assembly process. And then we merge it with the original EO. We represent each process and analyze current state of production process with the merged EO and $Prot{\acute{e}}g{\acute{e}}$ plug-ins. Moreover, we can analyze dependency relations among the workflow elements. Through the case study, we have found the effectiveness of EO in business management and process management in complex heavy industries.

This paper provides theoretical deformation of lean concept and its application for usage of building information modeling (BIM) process. Recently, much research is focused on application of lean concept for more efficient usage of BIM. The lean theory and its basic function and feature is based on manufacturing industry. The manufacturing process can be improved by process re-engineering steps of lean concept which consist of the steps of value, value stream, flow, pull, perfection. However manufacturing process and construction process has different characteristics. Due to the differences, five steps of the traditional lean's process re-engineering can't be directly applied to the BIM based engineering process. In order to solve this problem, we conduct analysis on the characteristics of the manufacturing process and BIM based engineering. We propose modified and expanded concept of lean for process re-engineering and the modified theory was applied to the mechanical, electrical and plumbing (MEP) coordination process. Through the proposed 8 steps of methodology, 2D based process was changed to integrated and using BIM based MEP coordination process. In addition, the results showed the potentiality of cost reduction and process improvement. The results of this study can be a foundation for the theoretical combination of lean and a variety part of construction engineering process.

The domestic construction companies have implemented a various of management methodology and tools for time management. However, the work completion rate versus work plan have a big difference with the planned work completion rate previously despite of implementing the time management methodology and tools. The research searches the problems that the previous time management process and tools focusing on the management factors that can be controlled. Also, It suggest the improvement direction for these limits.

All sorts of technique for schedule progress management is being developed recently. These can change and develop the abstractive concept model to a detailed model that describes the visual 3D image about a schedule plan. but, this technique is troublesome, because this requires the handwork by means of connection between 3D-CAD and scheduling Program. In this study, the process of real-time schedule progress control system using the integrated database by 3D-CAD object information system and schedule module is presented. This study present the process of a schedule progress management using IDEF0 model, and the process of real-time schedule progress management using RFID system. Through this study, we want to realize the rapid generation of estimated schedule information and to simulate and analyze actual schedule information by real-time.
