An approach to software architecture evaluation with the 4+1 view model of architecture

Architectural evaluation to determine a software architectures fitness with respect to its desired quality attributes is one of the most important issues in architecture-based software development. However, existing techniques have too many limitations for widespread application, such as the inappropriate representation of architecture and ambiguities in the evaluation process. Therefore, this paper presents an approach to evaluate software architecture with a 4+1 view model in UML. Our approach is divided into three main areas of activity: the work involved in preparation, execution, and completion of the evaluation. By performing these activities, architecture evaluation can be explicitly described and its result can be systematically organized based on the 4+1 view model. In addition, we show the practical applicability and features of our approach via an ATM example.

CAS/sup 2/: context awareness service system based on wireless sensor networks

In recent years, the appearance of ubiquitous computing provides a fair opportunity to access diverse information and service at anyplace, anytime for users. Furthermore, those services need system architecture and context-aware and, furthermore, location-aware technologies are essential. In this paper, we suggest that a system architecture (CAS2) for handling context information based on wireless sensor network (WSN) that can provide diverse and convenient services to user with only minimum actions by collecting context information of the user in real-time. CAS also provides optimized services to each user based on the context information

Framework for extending RFID events with business rule

Radio frequency identification (RFID) technology is believed to be the next revolutionary step in supply-chain management. Complex process simplification using RFID technology can offer particularly important benefits to many enterprises. To derive real benefit from RFID, the application must rapidly implement functions to process the large quantity of event data generated by RFID operations. For this reason, developers are forced to implement systems to derive meaningful high-level events from simple RFID events. Although applications could directly consume and act on RFID event, extracting the business rules from the business logic leads to better decoupling of the system, which consequentially, increases maintainability. In this paper, we describe an RFID business aware framework for extending RFID events using business rules, and then processing these to show complex events.

An approach to quality achievement at the architectural level: AQUA

Architecture-based software development plays an important role in successfully developing and managing large and complex software systems. Recently, there have been a number of studies for designing, evaluating, or transforming architectures. However, there is not much work being done for closely connecting an architectural evaluation with an architectural transfor-mation in order to achieve quality attributes during the architecture-based software development. For this reason, it is still difficult to achieve consistently quality attributes at the architectural level. This paper presents an approach to quality achievement in architecture-based software development, which is called AQUA. The AQUA involves two distinctive activities, which are architectural evaluation and transformation, but these activities can be seam-lessly combined through producing relevant artifacts based on the design decisions that led to the architecture. Due to the proposed approach, we can expect to achieve quality attributes in architecture-based software development.

A Design of R&D Planning Workbench Based on Research Outcome Analysis

Open collaboration based R&D activities such as research planning, development, and sharing of outcome has become an important issue recently. However, a information analysis system for supporting open collaboration based R&D planning is not sufficient. For this reason, R&D planning is dependent on the knowledge of a few planning experts, rather than the result of information analysis. This paper proposes a service model for supporting research planning based on outcome analysis in the phase of R&D planning, called R&D planning workbench. The R&D planning workbench is composed of R&D planning activities, R&D planning support services, and three different types of outcome analysis tools. We expect to enhance competitive power by constructing global collaborative network, promoting strategies by objective evaluation respect to research performance of individuals or institutions.

National repository of papers based on open access

Efforts to open and share research outcomes (publications, data, etc.) by public funds have been performed. And efforts to spread knowledge more easily and quickly have been also promoted. However, in Korea, we do not manage the research outcomes as core assets that can be produced and reused by public funds. In this paper, we analyze the characteristics of overseas studies in terms of deposition, management and utilization of papers produced by the publicly funded research. In addition, we proposed a project to build a national repository based on open access so that public research papers can be integrated and managed at national level.

Design of a Personalized Service Model for Developing Research Support Tool

최근 정보기술과 모바일 환경의 발전에 따라 서비스의 패러다임이 웹에서 앱 중심으로 다시 변화하고 있 다. 또한 R&D 투자 증대에 따라 연구자의 R&D 생산성 제고를 위한 노력들이 중요하게 인식되고 있다. 본 연구에서는 연구자의 R&D활동을 지원할 수 있는 연구지원 도구 개발을 위한 개인화 서비스 모델을 설 계하였다. 이를 위하여 R&D 과정에서 연구자들의 정보활동 관점에서 기존의 연구지원 서비스들을 비교하 였다. 또한 정보와 데이터의 공개·개방, 개인정보보호 강화, 소셜 네트워킹 서비스 대중화, 콘텐츠의 최대형 화, 웹 플랫폼 기술 진화 등의 정보환경 변화를 개인화 관점에서 분석하고, 개인화 서비스 개발의 방향성을 정의하였다. 이를 바탕으로 연구지원 도구의 개인화 서비스 모델을 기능, 콘텐츠, 운영 뷰로 구분하여 설계 하고, 이를 구현하기 위한 개인화 설계 목표와 원칙들을 표준, 참여, 개방으로 정의하였다.

Conceptual Design of a Network-Based Personalized Research Environment

With advancement in information technologies and a better mobile environment, virtual and personal research environments can be made available for researchers. On the other hand, as more investment is being made in R&D, the efforts to enhance R&D productivity are becoming important. This study proposes a conceptual design of network-based personalized research environment that is called NePRE for developing the tool to assist researchers in their R&D efforts. It can be more easily utilized by researchers in their R&D information activities. To do this, we analyze existing research support environments in terms of R&D information activities. And we also analyze changes of information environment in terms of personalization. Subsequently we define three design principles of NePRE for personalization. Finally we define its key functions to assist researchers with respect to six R&D information activities.

Design and Implementation Issues for Expanding Information in a Service (NTIS)

National Science & Technology Information Service(NTIS) established a system that collect, manage and service the information of national Research and Development(R&D) program in Korea. However, the existing system can’t support monitoring of detailed fund usage results of projects and commissioned projects. To solve this problem, NTIS need to collect additional detail information including each expense items of projects, co-work projects, commissioned projects and co-research information. We designed NTIS database structure for the improvement project and implemented the registration and management functions at the Standard Information Management Service(SIMS).

Similar Document Retrieval among the Different Kind of National R&D Outcomes

All research or development activities produce many kinds of outcome such as article, patent, research report, human resources information, application method for some equipment, experimental data and so on. The NTIS (National Science & Technology Information Service) in Korea offers a unified search service using national R&D outcomes data to researchers. But this function does not meet the academic requirements of users who want to use the relevance of papers, patents, research reports, etc. It is needs to display related documents together when a user stays in a page which offers detail metadata about one outcome, this helps users to diminish effort to search their interesting information. In this paper, we propose the method for similar document retrieval among heterogeneous kinds of R&D outcomes. A combination of user query and search factor extracted from the search engine are used to search some similar documents, and the boosting technology using the author field and subject code (S&T standard code) field is applied to document ranking process. We show usefulness of proposed method in this paper as developing the intelligent system of NTIS or many metadata search services.
