현재 컴포넌트 기반 소프트웨어 엔지니어링의 접근은 소프트웨어 컴포넌트 인터페이스 디자인과 실행에 중심을 둔 경향이다. 컴포넌트 기반 소프트웨어 개발을 하기 위하여, 전체 시스템을 분석하는 것은 복잡하고, 이해하기 어렵다. 이를 위하여 aspect 기반 컴포넌트 개발방법을 도입한다. Aspect 기반 개발에서는 필요로 하는 컴포넌트를 표현하기 위하여 provide 와 require 를 사용한다. 또한 Aspect 기반 컴포넌트 엔지니어링을 위하여 컴포넌트 사이의 provide/require 서비스에 대한 분류와 추론을 위하여 다른 컴포넌트와 함께 이용할 수 있는 방법을 제안한다. 이 방법은 개발자들은 전체 시스템 개발을 위해 필요로 하는 적합한 컴포넌트의 provide/require 을 사용하여 접근하기 때문에 컴포넌트 검색, 합성, 재사용에 도움을 줄 수 있다. 컴포넌트 aspect 정보의 확장을 위하여 XML 문서 포맷을 사용함으로써 서로 다른 환경에서도 사용할 수 있도록 명세 하였다.

In order to increase extensibility and reusability of business components, the variable things need to be analyzed from the analysis phase and identified as components. In this paper, we propose a rule-based analysis pattern, which can effectively extract object-based main concepts from a variable business process in the analysis phase and identify a variable business component by applying the pattern to the UML Components development process. It can make analysis artifacts consistent and readable for analysts with different level of knowledge and experience to apply the pattern to analysis of rule-based variable business processes. And also, variable business components can be easily identified by applying the pattern to the UML Components development process. In order to prove the feasibility of the pattern, we have applied the pattern the deposit and import/export subsystem of the banking domain. According to our experience, we can make the same business conceptual models between the deposit and import/export subsystem due to the main concepts suggested by the pattern and effectively identify a variable business components in the UML Components development process.

Modeling and simulation technology is being used in various fields. Especially in the field of military, Simulation-Based Acquisition (SBA) is recognized as a essential policy. To effectively carry out SBA, modeling and simulation techniques should be applied in the whole life-cycle for the weapon system development, and the framework and tools which can help the rapid component development and reusability are needed. In this research, we use the simulation framework based on modeling formalism for enhancement of reusability and a GUI-based modeling environment for rapid M&S component development. The Proposed framework can act as plug-in components on the basis of XML-based object model, so that the flexible design is possible for the change of the model and simulation structure. In addition, our methods are effective to implement the functions for supporting simulation such as the model data logging and communication with external systems. In this paper, we describe an architecture and functions for the framework and tools.

The emergence of new technologies and their implementation by different manufacturers of electronic devices are experiencing an ascending trend. Most of the time, these protocols are expected to reach a certain degree of maturity, and electronic equipment manufacturers use simplified communication standards and interfaces that have already reached maturity in terms of their development such as ModBUS, KNX or CAN. This paper proposes an IoT solution of the Smart Home type based on an Analysis and Prediction System. A data acquisition component was implemented and there was defined an algorithm for the analysis and prediction of actions based on the values collected from the data update component and the data logger records.

Component-based development(CBD) has been generalized in industry to master the complexity and reduce the development cost and time. However, current CBD practice is developing the component which is dependent on single application[l][2]. Therefore component variability is emphasized to reuse the component in many family members in a domain[8]. However, components are developed for the reason of replaceability rather than the reusability which is the main purpose of the component due to the insufficiency of the study of component variability definition and type[3]. In this paper, we formally specify the component variability reflecting the characteristics of the component to increase the component reusability. We define the logic variability which was recognized as the existing component variability and we propose all types of variability existing in the component by suggesting three more variability types. And we propose the component variability scope which makes us estimate and verify the number of cases of the variability when we customize the component. We propose these component variability types and scope through formal specification. By applying these techniques in developing components, we can develop high quality components reusable in many family members.

Component Based Development (CBD) is appealing as a technology to improve the productivity of software development through component reuse. Model Driven Architecture (MDA) is a new development paradigm which automatically generates application by transforming design models incrementally. Since both reusability of CBD and model transformation of MDA increase software productivity. integration of two technologies is desirable. To enable this technology integration, we need to devise a UML profile for specifying component design as a PIM. In this paper, we first define a meta-model for components, and propose a UML profile which is used to specify elements of component design as PIM. Since the proposed profile is based on Meta Object Facility (MOF) from which is MDA is derived, it is consistent and compatible with existing MDA methods and tools.

A software development using components reuse is an useful method to reduce the software development cost. But a retrieval method by the keyword and category classifications is difficult to search an exact matching component due to components complexity in component reuse. Therefore, after different existing methods are examined and analyzed, an effective classification and retrieval method using XML specifications and the system architecture of components integrated management based on it are presented. Many discording elements of DTD which is component meta-expression exist in components retrieval. To compensate it, this retrieval method using estimations of precision and concision is effective one to catch considerable matching preference components. This method makes possible to retrieve suitable components having better priority due to searching similar matching components that are difficult in an existing keyword matching method.

GPS/GIS Related Information Technology evolves drastically and a great quantity of spatial information is available to users who require highly qualitative spatial information services. Hence the development of GIS tools that can improve position accuracy and maintenance efficiency is required. To meet various requirements from users. we developed a GPS data processing component based on OLE/COM by utilizing GDK which is a unique domestic GIS product. Also we developed an application package that includes the GPS data processing component to implement GPS into GIS. The development of GPS data processing component will contribute toward the expansion of component-wise GIS softwares.
