Component-Based Software Engineering (CBSE) is widely accepted as new paradigms for building applications with reusable assets. Mismatch problems occur while integrating the assets and make a burden in CBSE. Therefore, a larger-grained reuse unit than a component such as a framework is required, and it consists of relevant components, connectors and domain-specific architecture. The benefits of frameworks over components are commonly known, however, the key elements and internal structure of framework has not been clearly defined. We believe most of the framework models proposed in recent works remain at conceptual level. In this paper, we propose a practical-level framework reference model, and define key elements of frameworks. The research goal is to precisely identify concrete elements of a framework, inter-connection of components within a framework, extended notion of connectors, and tailored meaning of architecture In a framework. Hence, the proposed framework can be practically implemented in common object-oriented languages and with middleware such as lava, J2EE, CORBA Component Model (CCM) and NET.

근래의 소프트웨어 관련업계에서는 소프트웨어 개발 및 관리에 있어 소프트웨어구조를 중심으로 생산성 및 품질의 극대화를 추구하고 있다. 또한 소프트웨어 컴포넌트 관련 기술 및 컴포넌트 기반 소프트웨어 개발 방법론에 대한 연구도 활발히 진행중이며, 많은 응용기술들이 나오고 있다. 소프트웨어 구조는 소프트웨어를 컴포넌트로 구성하고 그 사이의 상호작용을 커넥터를 이용해 기술함으로서 전체적인 구조를 분석하고 유지하는데 필수적인 요소로 고려된다. 본 연구에서는 우리가 개발한 HappyWork라는 모델링 도구를 사용하여 소프트웨어 구조를 설계하는 기법을 설명한다. HappyWork를 이용한 소프트웨어 구조 설계 과정에는 System Context Diagram, Component Diagram, Component Sequence Diagram과 같이 세 가지 다이어그램이 사용되며, 이 Diagram들을 User, System, Component, Connector와 같은 네 가지 element들로 구성된다.

Prefabricated exterior wall panel is the main non-load-bearing component of assembly building, which affects the comprehensive performance of thermal insulation and durability of the building. It is of great significance to develop new prefabricated exterior wall panel with durable and lightweight characteristics for the development of energy-saving and assembly building. In the prefabricated sandwich insulation hanging wall panel, the selection of material for the outer layer and the arrangement of the connector of the inner and outer wall layers affect the mechanical performance and durability of the wall panels. In this paper, high performance cement-based composites (HPFRC) are used in the outer layer of the new type wall panel. FRP bars are used as the interface connector. Through experiments and analysis, the influence of the arrangement of connectors on the mechanical behaviors of thin-walled composite wall panel and the panel with window openings under two working conditions are investigated. The failure modes and the role of connectors of thin-walled composite wallboard are analyzed. The influence of the thickness of the wall layer and their combination on the strain growth of the control section, the initial crack resistance, the ultimate bearing capacity and the deformation of the wall panels are analyzed. The research work provides a technical reference for the engineering design of the light-weight thin-walled and durable composite sandwich wall panel.
