As CBD technologies and researches have been matured, component framework as a larger reuse unit than component is being introduced. Especially issues related with adaptation and integration of components in CBD are being raised as a new research topic. The component framework is given as a solution to resolve these issues. However, current approaches don't suggest a sound and comprehensive reference model and development process applying reference model. In order to develop practical and stable component framework, reference model and concrete guidelines are essential elements. In this paper, we propose a generic reference model integrating existing reference models and a design technique of component framework based on it. Especially, we propose concrete and pragmatic guidelines such as how to design component framework architecture's view and style, how to design commonality and variability of component framework, how to design macro workflows among components, and so on. We believe that the proposed reference model becomes basis for component framework development, and the proposed design technique will support reliable and effective development of the component framework.

기업 등 조직의 경계를 초월한 분산 환경에서의 정보교환은 인터넷이 확산되면서 더욱 증가하고 있다. 특히 전자결재나 기업 간 상거래, 공동작업을 위한 정보나 메시지 교환이 폭발적으로 증가하고 있는 것이 현실이다. 본 논문은 다양한 정보들이 분산된 노드와 사용자간 의미 있는 메시지로 교환될 수 있도록 지원하는 메시지 엔진을 설계하는 연구이다. 특히 자바 메시징 서비스의 모델을 기본으로 하여 메시징 요구사항을 충족함과 아울러 다양한 인터페이스의 제공에 초점을 두기보다는 핵심적인 메시징 서비스 모델에 치중하여 다양한 응용에 통합되어 활용될 수 있도록 설계하였다.

본 연구의 목적은 현재 국내에서도 스마트워크가 확산되고 있는 바, 스마트워크의 도입이 직무성과에 어떠한 영향을 미치는지를 분석하고자 한다. 스마트워크를 도입하여 사용하고 있는 국내 대기업, 중소기업에 근무하는 직원들을 대상으로 다수의 설문지를 통한 실증분석 즉 빈도, 요인, 신뢰도 분석을 실시하였고, 통계분석의 도구인 PROCESS Macro를 사용하였다. 연구결과는 다음과 같다. 첫째, 스마트워크 도입기업의 IT자원은 직무성과에 유의한 영향을 미치는 것으로 나타났다. 둘째, 스마트워크 도입기업의 IT자원은 집단지성과 독립적으로는 직무성과에 영향을 미치지 않는 것으로 나타났다. 셋째, 집단지성 중 개방과 협업이 IT자원과 업무개선 간을 매개하고, 집단지성 중 참여, 개방 및 협업이 IT자원과 업무협조 간을 매개하는 것으로 나타났다. 향후에는 동일 산업군내에서 스마트워크 도입 기업과 미도입 기업간 재무성과를 비교하거나 동일 기업 내에서 스마트워크 도입 전후의 재무성과를 동태적으로 비교하는 정량적인 분석이 필요하다.

A multi-agent and web based engineering framework concerning the automation of fatigue durability analysis for welded bogie frame of railway vehicles is presented. Mostly, this kind of design or analysis includes complex workflow, huge amounts of information processing, and problem solving. Macro programs of I-DEAS, APDL of ANSYS, and in-house fatigue code are utilized for parametric geometry representation, automatic mesh generation, static stress analysis, fatigue durability analysis, post-processing, and data sorting. The engineering framework is implemented on the JADE. Since every task requires a fairly complex process and specialized knowledge, the multi-agent based framework is very useful to keep the independency among several disciplines or tasks and to use distributed hardware and software resources. All engineering programs are integrated by XML wrapper. Related database of the engineering framework and web based user interfaces are also developed. A parametric study is carried out to take into account the effect of geometrical change of transom support bracket on its cumulative fatigue damage. The developed engineering framework reduced remarkably the time and costs required in designing and solving engineering problems.

Background: To describe domain knowledge consistently and precisely, the establishment of a controlled vocabulary, a so-called ontology, is essential. Internationally, the plant ontology (PO) in the ecology field has been developed for the anatomy and developmental stages of plants in English, Spanish, and Japanese, but there is no Korean version of the PO due to a lack of knowledge on standardization for Korean plants. Objectives: We aimed to establish a Korean plant ontology with core PO architectures. Methods: The latest ontology web language (OWL)-formatted raw version of the PO was collected from the PO consortium site. A formal workflow process and OWL file-handing tools for efficient Korean content development were conducted and executed. Results: The macro- and micro-perspective frameworks of the PO were presented by analyzing the upper model and the internal OWL-leveled physical structure, respectively. We developed and validated Korean knowledge content for a total of 1,957 classes included in the PO and transplanted them into an ontology modeling system. Conclusions: A Korean plant ontology was established for international harmonization through improved compatibility and data exchangeability with multilingual environmental and ecological knowledge bases.
