The top-down method for SOA delivery is recommended as a best way to take advantage of SOA. The core step of SOA delivery is the step of service modeling including service analysis and design based on ontology. Most enterprises know that the top-down approach is the best but they are hesitant to employ it because it requires them to invest a great deal of time and money without it showing any immediate results, particularly because they use well-defined component based systems. In this paper, we propose a service identification method to use a well-defined components maximally as a bottom-up approach. We assume that user's inputs generates events on a GUI and the approximate business process can be obtained from concatenating the event paths. We first find the core GUIs which have many outgoing event calls and form event paths by concatenating the event calls between the GUIs. Next, we adapt sequential pattern mining algorithms to find the maximal frequent event paths. As an experiment, we obtained business services with various granularity by applying a cohesion metric to extracted frequent event paths.

Residential satisfaction is one of the most studied topics in the field of housing. This paper is to find factors that correlate with residential satisfaction of the residents and study the satisfaction differences between different groups of residents in urban village in Shenzhen. A questionnaire of 61 satisfaction variables grouped into five components based on literature review and actual situation in targeted village was conducted to find out factors related with residential satisfaction in urban villages. These components are dwelling unit, building conditions, village environment, neighborhood environment, and neighbors. Factors were extracted from these components and the correlations between the factors and residential satisfaction were analyzed by using Pearson's correlation coefficient to find out factors that most correlate to residential satisfaction. Satisfaction differences of the five components between respondents with different characteristics were also studied. The result showed all the factors positively correlated with residential satisfaction and residential satisfaction correlated the most with the factors of perception and information exchange, room sizes, and air condition and quality. The characteristics of gender, unit type, and interaction frequency with neighbors contributed to different satisfaction with certain components.

프로그램을 개발하다보면 많은 분야에서 파싱 작업을 필요로 하게 된다. 이러한 필요에 의해 개발되는 파서는 Lex와 Yacc과 같은 도구에 의해 생성되는 경우도 있지만, 도구의 사용이 어렵기 때문에 프로그램으로 직접 작성하는 경우도 많다. GUI 방식으로 아이콘을 이용해서 파서를 작성할 수 있다면, 파서를 필요로 하는 많은 프로그램 개발에서 손쉽게 사용될 수 있을 것이다. 이 논문에서는 아이콘을 이용해서 파서를 생성할 수 있는 방법에 대해 기술하고 있다.

This paper proposes a method to classify and retrieve components in repository using the idea of domain orientation for the successful reuse of components. A design pattern was applied to existing systems and a component classification method is suggested here to compare the structural similarity between each component in relevant domain and criterion patterns. Classifying reusable components by their functionality and then depicting their structures with a diagram can increase component reusability and portability between platforms. Efficiency of component reuse can be raised because the most appropriate component to query and similar candidate components are provided in priority by use of-SARM algorithm.

This research is the method that develops the efficient Source Head and the performance of Ion Implanter. Source Head is used during 20 days because Source Head's life time is different from the life time of most components. Components which is replaced to remake the Source Head is very expensive, and moreover, the above of 50% is used with one time. In this research, as we applied the influx method of the atom in aerial distributed method, obtained the effect which suppresses the portion which occurs with loss of thermion and is a possibility of lowering the pressure of the Arc. And then We it will be able to suppress be imbrued of the Chamber.

OPC has made it to improve the development of control and monitoring software. But it is difficult to understand COM/DCOM model that is a base technology of OPC and complex communication setting between OPC Server and OPC Client. Therefore, in this paper, we design and implement ActiveX based components that are enable to solve these problems. Implemented components provide a method for simple communication between OPC Sewer and OPC Client and a GUI environment for easy and fast setting of communication information. Also, they provide the architecture fur efficient management of OPC Server's data. By using implemented component, easy development and efficient maintenance of OPC Client can be supported.

A tape feeder of a SMD(Surface Mount Device) mounter is a device that sequentially feeds electronic components on a tape reel to the pick-up system of the mounter. As components are getting much smaller, feeding accuracy of a feeder becomes one of the most important factors for successful component pick-up. Therefore, it is critical to keep the feeding accuracy to a specified level in the assembly and production of tape feeders. This paper describes a tape feeder inspection system that was developed to automatically measure and to inspect feeding accuracy using machine vision. It consists of a feeder base, an image acquisition system, and a personal computer. The image acquisition system is composed of CCD cameras with lens, LED illumination systems, and a frame grabber inside the PC. This system loads up to six feeders at a time and inspects them automatically and sequentially. The inspection software was implemented using Visual C++ on Windows with easily usable GUI. Using this system, we can automatically measure and inspect the quality of ail feeders in production process by analyzing the measurement results statistically.

A performacne simulation model of the PT6A-62 turboprop engine using the $SIMULINK^R$ was proposed to predict transient and steady state behaviors. The $SIMULINK^R$ has several advantages such as user-friendliness due to the GUI(Graphic User Interfaces) and ease in the modification of the computer program. The $SIMULINK^R$ model consists of subsystems to represent engine gas path components such as flight initial subsystem, compressor subsystem, burner subsystem, compressor turbine subsystem, power turbine, exhaust nozzle subsystem and integrator subsystem. In addition to subsystems, there are search subsystems to find an appropriate operating point by scaling from the 2-D components look-up table, Gasprop Subsystem to calculate the gas property precisely. In case of steady state validation, performance results analyzed by the proposed $SIMULINK^R$ model were agreed well with the analysis results by the commercial GASTURB program. Moreover in validation of the transient model, it was found that performance simulation results by the proposed model were reasonable agreement with analysis results by the well-proved computer program using FORTRAN.
