In order to implement clean technology to Petro-chemical process, simulation package of given process should exist. In this paper, reaction and recycling parts of a process are explained using EA process and MEK process respectively so as to explain how to make simulation package. Based on simulation package, several options are generated and feasibility tests are performed.

In the present study, we developed a methodology to minimize a waste solution produced in the etching process. The condition for the optimization of the GRS process was studied on the basis of laboratory experiment and field test as well as pilot test. Through the study, we analyse the relation of the main process variables and the yield of the GRS process. The application of the new operation condition and the reactor internal modification results in 10% yield improvement in the GRS process and accordingly decreases a wasted solution.

This paper presents the core technology of Construction Business Process Automation to model and automate construction business processes. Business Process Reengineering (BPR) and Automation (BPA) have been recognized as one of the important aspects in construction business management. However, BPR requires a lot of efforts to identify, document, implement, execute, maintain, and keep track thousands of business processes to deliver a project. Moreover, existing BPA technologies used in existing Enterprise Resource Planning (ERP) systems do not lend themselves to effective scalability for construction business process management. Application of Workflow and Object Technologies would be quite effective in implementing a scalable enterprise application for construction business processes by addressing how: 1) Automated construction management tasks are developed as software components, 2) The process modeling is facilitated by dragging-and dropping task components in a network, 3) Raising business requests and instantiating corresponding process instances are delivered, and 4) Business process instances are executed by using workflow technology based on real-time simulation engine. This paper presents how the construction business process automation is achieved by using equipment reservation and cancellation processes simplified intentionally.

Technology commercialization is a reward process for companies' various trials and investment to develop technologies, which can be regarded as a way to figure out company's business performance. To successfully attain companies' purpose via technology commercialization, a variety of knowledge which triggers and completes business activities are needed. This paper suggests a methodology to analyze problems and solutions around the technology commercialization process in terms of knowledge distribution status, especially focused on Korean SMC cases. The knowledge map of this paper is constructed from the knowledge networks and identifies problems and solutions of the target process. A case study for applying proposed concepts to SMC's cases is also performed by checking knowledge distribution status and extracting practical implications. This paper's ideas can be regarded as one of references for SMCs to prepare technology commercialization with guaranteeing facilitated knowledge distribution and utilization.

Position reading devices such as optical encoders are most essential components in numerical control (NC) machines and robots. Fabrication process of optical NC-scales was developed for domestic production. The whole process using photo-lithographic techniques consists of about 10 steps. The process parameters were to be carefully determined through many trial experiments. The scale marks of metal film was printed on a glass substrate. The optimum values of various process parameters were extrilcted. The quality of scale marks was attributed to the each process parameters.

The PC system has advantages in terms of project management, such as shortening the construction period and reducing costs. However, it is difficult to activate the technology due to insufficient application of the technology. Therefore, there is a need for a strategy to expand and activate the PC system. This study is a basic research for PC construction project management, and its purpose is to derive the entire construction process from factory production of PC components to on-site construction. In this study, the construction process of the PC system was derived through literature review, and the main matters for the construction process management of PC system were confirmed in the analysis process. In the future, the results of this study are expected to be used as basic data for research for PC project management, such as deriving construction classification and calculating construction periods.

In order to design an OLED(Organic Luminescent Emitting Device) evaporation system, geometric simulation of film thickness distribution profile is required. For the OLED evaporation process, thin film thickness uniformity is of great practical importance. In this paper, a geometric modeling algorithm is introduced for process simulation of the OLED evaporating process. The physical fact of the evaporating process is modeled mathematically. Based on the developed method, the thickness of the thin-film layer can be successfully controlled.
