Component users must customize components they obtain from providers, in order to fit them to their own purposes. Normally, a component consists of black-box parts and white-box parts. Component users customize a component by modifying white-box parts of a component, and the customization faults appear through the interaction between black-box parts and white-box parts. Customization testing could be an integration testing of these two parts of a component. Also, customization testing in CBSD should select effective test data to reduce the testing cost, since CBSD aims to reduce the development cost. Therefore, this paper proposes a customization testing technique based on COM architecture through analyzing many COM components, and the technique selects effective test data. This paper evaluates the effectiveness of the test data selected by the proposed technique through an empirical study. It applies the techlique to a large-scale component-based system, Chamois, and it shows that the technique enables us to test customized COM components that run in a real component-based system

It is well recognized that component-based development (CBD) is an effective approach to manage the complexity of modem software development. To achieve the benefits of low-cost development and higher productivity, effective techniques to maximize component reusability should be developed. Component is a set of related concepts and objects, and provides a particular coarse-grained business service. Often, these components include various message flows among the objects in the component, called 'business workflow`. Blackbox components that include but hide business workflow provide higher reusability and productivity. A key difficulty of using blackbox components with business workflow is to let the workflow be customized by each enterprise. In this paper, we provide techniques to model the variability of family members and to customize the business workflow of components. Our approach is to provide formal specification on the component variability, and to define techniques to customize them by means of the formalism.

It is very useful to perform the surgery simulation before implanting TAH(Total Artificial Heart} in a patient. The space of chest and the shape of vessels are different from patient to patient. So, It is desirable to customize a TAH design to the anatomy structure of a patient. Several studies are performed to visualize and explain the 3D structure of heart. These studies are performed using 2-dimensional ref or mated images and simple measurement. Anatomy structure of a human heart is not so simple. It is 4dimensional structure ; 3-dimensional plus time, heart beating. 3-dimensional reconstruction schemes of medical images developed for about 10 years are usually categorized into two types of rendering technique ; surface rendering and volume rendering. Volume rendering is preferable in medical image processing field because this technique can be applied without considering the complexity of geometry and change of field of interest. The usable space in the chest of patient can be measured by 3D volume matching of patient trunk and TAH model. This space changes with time. In this research we have developed the 4-dimensional volume match program of patient and TAH model. 3-dimensional rendered set of volumes along time were used to simulate TAH fitting trial. The quantitative measurement from this simulation could be applied to customize TAH design.

Quality of the web service is one of the most important elements as various web services provide diverse functionality, and therefore, it is more and more difficult to satisfy customer's needs. Since the existing UDDI registry provides the basic information such as name and URL of a web service, users are having hard times to choose and customize their web service. In this paper, we propose an extended UDDI architecture for providing quality data of a web service. And in this architecture, we used an automated collection technique of data for testing web service which provides quality information to the users, including response time, throughput, availability, reliability and accessibility. With this new architecture, users and web developers can benefit from web services that customize information for the users and this ensures reliability of web-based applications.

The goal of wireless sensor networks is to collect sensing data on specific region over wireless communication. Sink node gathers all local sensing data, processes and transmits them to users who use sensor networks. Generally, senor nodes are low-cost, low power devices with limited sensing, computation and wireless communication capabilities. And sensor network applies to multi-hop communication on large-scale network. As neighboring sensor nodes have similar data, clustering is more effective technique for 'data-aggregation'. In cluster formation technique based on multi-hop, it is necessary that the number of cluster member nodes should be distributed equally because of the balance of cluster formation To achieve this, we propose a method to customize cluster member nodes for energy-efficiency in wireless sensor networks.

Component-Based Development (CBD) has emerged as a new effective technology that reduces development cost and time-to-market by assembling reusable components in developing software. The degree of conformance to standards and common features in a domain largely determines the reusability of components. In addition, variability within commonality should also be modeled and customization mechanism for the variability should be designed into components. Enterprise JavaBeans (EJB) is considered a most suitable environment for implementing components. However. the reusability of EJB is limited because EJB does not have built-in variability design mechanisms. In this paper, we present efficient variability design techniques for implementing components in EJB. We propose a method to customize the variability of EJB-based components by applying three variability design mechanisms; selection, plug-in, and external profile. And we elaborate the suitable situations where each variability design mechanism can be applied, and conduct a technical comparison to other approaches available.

소프트웨어를 개발하는데 미리 구현된 블록을 사용하여 소프트웨어 개발비용과 시간을 단축할 수 있다. 이와 같이 미리 구현된 블록을 컴포넌트(Component)라고 하며 컴포넌트를 실행 단위로 개발자에게 인터페이스만을 제공하여 내부 상세한 부분을 숨기므로 쉽고 바르게 대행 어플리케이션을 개발할 수 있다. 개발자는 완전히 내부를 볼 수 없는 블랙 박스(Black Box) 형태의 컴포넌트를 사용한다. 그러나 개발자들은 개발 도메인의 특성에 맞게 속성 및 워크플로우(Workflow)의 변경을 원하기 때문에 커스터마이즈(Customize)할 수 있는 방법이 있어야 한다. 기존의 커스터마이즈 기법은 컴포넌트의 속성을 변경하는 것에 국한되어 있다. 본 논문에서는 비즈니스 측면에서 속성 뿐만이 아니라 컴포넌트 내부의 워크플로우도 변경할 수 있는 기법을 제시한다. 기존에 워크플로우를 변경한다는 것은 컴포넌트 내부를 개발자가 이해하고 코드 수준에서 수정해야 하는 화이트 박스(White Box)이지만, 본 논문에서는 워크플로우의 변경을 화이트 박스가 아니라 블랙 박스 형태로 컴포넌트 인터페이스 만을 이용해 커스터마이즈 할 수 있다. 본 논문에서 제시하는 컴포넌트 커스터마이즈 기법은 특정 비즈니스 측면에서 도메인에 종속적인 특성을 가지며 컴포넌트를 좀더 범용적으로 사용할 수 있는 향상된 커스터마이즈 기법을 제시한다.

In this paper, we discuss the user-customized interaction for intelligent home environments. The interactive system is based upon the integrated techniques using both speech and face recognition. For essential modules, the speech recognition and synthesis were basically used for a virtual interaction between user and proposed system. In experiments, particularly, the real-time speech recognizer based on the HM-Net(Hidden Markov Network) was incorporated into the integrated system. Besides, the face identification was adopted to customize home environments for a specific user. In evaluation, the results showed that the proposed system was easy to use for intelligent home environments, even though the performance of the speech recognizer did not show a satisfactory results owing to the noisy environments.

The enterprise resource planning(ERP) system becomes more popular as a vehicle of realizing an integrated information system, because this system not only facilitates the reengineering of processes in a firm but also provides the function of generating consolidated financial statements. However, ERP vendors have unsuccessfully provided methodologies on the customization of ERP packages although one of the important issues during the implementation of an ERP package is how to customize it. The purpose of this paper is to build a strategy on the successful customization of ERP packages. The result from the analysis of interviews with 25 consultants and experts in the ERP field recommends 14 customization strategies of an ERP package in the four areas of a firm: management, technology, organization, and environment. The analysis of the feedback from the consultants and experts generates the ranking of the 14 customization strategies.
