In conventional analysis methods, data and process are loosely coupled for building information systems. Several object oriented approaches have been proposed to integrate data and process. However, object oriented analysis requires a radical paradigm and thus system analysts find difficulties in generating object models direcctly from end users. To alleviate these difficulties, this paper proposes a methodology for deriving an object model by using structured analysis results. Objects are obtianed primarily from entities in Entity-Relationship Diagram. Methods are obtained through the analysis of the relationship between processes and data stores in Data Flow Diagram Methods are assigned to the objects by using object/process matrices. A real-life case is illustrated to demonstrate the usefulness of the methodology.

Recently, many enterprises have attempted to capitalize knowledge assets on data warehouse (DW). It has been recognized as strategic core process to create corporate competitive advantage and implement enterprise e-biz strategies. However, most approaches to represent knowledge and decision process have limits in considering various knowledge types, their relationships and continuity in knowledge formulation. In addition, they are so inclined to one side such as concept-oriented frameworks or technology-oriented ones. They lack universal and wide-ranging features. This paper presents a comprehensive methodology to accumulate knowledge capital on DW via a properly grained hypermedia model. The methodology consists of three phases: knowledge requirement elicitation, hypermedia modeling, and system implementation. A real-life case for medical DW development is presented to demonstrate the usefulness of the proposed methodology. This methodology is effective when an organization accumulates knowledge assets to put the corporate e-biz or cre-biz strategy into practice.

Human Being is being that have the reason as well as body, and first liaison consists through this body justly with outside. The essence of environmental problem such as today can speak that is a harmful traces for health that leave in air, water, soil that pass body. Actual nature is 'Ecological nature', that is necessary for human life directly in survival and offer the integrated relations with harmony. This grafting of principle, that is a construction for architecture and interior architecture in environment furtherance, is required. This is not a subject of usefulness and contemplation, but essential approach the cogredience, that is forming connection directly with nature, is required. Therefore, this research does Questel about 'Nature epistemology, which nature and human's relation can be integrated by alive practical relation. Through this, the Relatedness of 'Natural environment and construction surrounding' is accomplished 'the whole unity' and this research wish to investigate basis that a actual human work's environment can be completed as 'Ecological nature'.

본 연구는 제 7차 교육과정에 의해 통합된 중학교 $\ulcorner$기술 가정$\lrcorner$ 교과에 대한 학습자의 흥미도와 실험 실습의 가치 또는 중요성과 실생활 활용도 등에 대한 학습자 인식을 알아보고자 실시되었다. $\ulcorner$기술 가정$\lrcorner$ 교과에 대한 흥미도는 성별에 따라 차이가 있었다. $\ulcorner$기술 가정$\lrcorner$ 교과에 대해서는 여학생들이 남학생들보다 더 많은 흥미를 보였으나, 영역별로 보면 가정영역에서는 성차가 없었으나, 기술영역에서는 남학생들이 여학생들보다 흥미도가 더 높았다. 학습자들은 $\ulcorner$기술 가정$\lrcorner$ 교과의 내용 이해나 동기 유발을 위해 실험 실습의 중요성을 인식하고 있었고 그에 비해 운영되는 실험 실습의 양에 관해서는 부족함을 보고하였다. $\ulcorner$기술 가정$\lrcorner$ 교과의 실험 실습의 중요도를 높게 인식할수록 실생활에서의 활용도도 높게 나타났다. 특히, 학습자가 활용도를 가장 높게 인식한 단원은 타 단원에 비해 '청소년의 영양과 식사', '컴퓨터와 정보처리'였으며, 활용도를 가장 낮게 인식한 단원은 주로 '자원관리와 환경', '제도의 기초'와 '기계의 이해'로 나타났다. 이러한 결과는 기술 가정 교과에 대한 학습자의 흥미도와 실생활에서의 활용도를 높이기 위해서, 실험 실습의 중요성을 부각시키되 학습자의 성별에 따른 단원별 활용도에서 인식 차이를 고려한 실험 실습의 운영 방안이 강구되어야 함을 시사해준다.

A data model is a diagram that describes the properties of different categories of data and the associations among them within a business or information system. In spite of its importance and usefulness, data modeling activity requires not only a lot of time and effort but also extensive experience and expertise. The data models for similar business areas are analogous to one another. Therefore, it is reasonable to reuse the already-developed data models if the target business area is similar to what we have already analyzed before. In this research, we develop a case-based reasoning system for data model reuse, which we shall call CB-DM Reuser (Case-Based Data Model Reuser). CB-DM Reuse consists of four subsystems : the graphic user interface to interact with end user, the data model management system to build new data model, the case base to store the past data models, and the knowledge base to store data modeling and data model reusing knowledge. We present the functionality of CB-DM Reuser and show how it works on real-life a, pp.ication.

This paper proposes a form-based distributed database design methodology ($FD^3$). The methodology consists of five design phases such as (i) form requirement analysis (ii) schema integration (iii) distribution analysis (iv) distribution design, and (v) local logical/physical design. In the $FD^3$, all the important design information for each phase is obtained by using an organizations forms, Users requirements are analyzed by using forms that contain logical and quantitative information for distribution design. $FD^3$ resolves naming conflicts by employing SQLs based on the form field data in the schema integration phase. Furthermore, $FD^3$ enhances the quality of distributed database design by incorporating communication costs into the design model. A real-life case is illustrated to demonstrate the usefulness of the $FD^3$.

Today, corporate knowledge plays a critical role in obtaining competitive advantage. It is often pointed out that corporate knowledge is expected to be able to support various efforts for process innovation. Accordingly, it is important to establish a systematic infrastructure for the acquisition of knowledge which can support business-critical tasks effectively. From this motivation, this paper proposes a framework to guide a series of acquisition procedures for task knowledge and shows how to intemperate with activities for an innovation purpose. Moreover, the useful components of task knowledge are proposed; the schema of the components is ultimately implemented as a repository in a system for the management of task knowledge. To demonstrate the practical usefulness of the framework and the schema components, a real-life case is illustrated.

The Semantic Web is an extension of the current Web in which information is given formal and explicit meaning. The Semantic Web enables computer programs to understand information contents and thus facilitates more efficient discovery, automation, integration and sharing of data. To create Semantic Web contents one needs appropriate tools. In this paper, we describe such a toolkit we have constructed. The most important feature of the toolkit is that it makes use of information extraction techniques for automatically annotating web page contents. Experiments with a real life application show promising results and demonstrate the usefulness of the toolkit.

International construction projects typically manifest difficult, complex, and varied types of risk exposures; because of this, there is a need for accurate evaluation of risk-integrated performances during the timeframe of project execution. Given the financial crisis currently affecting the world economy recession, risk management has become a more crucial part for the success of international project management. However, the majority of risk management approaches, particularly for overseas projects, are focused primarily on simple forms of checklists, formalization of risk variables affecting project performance for a specific phase, or more complicated computational methods that restricting practical utilization in real-world projects; moreover, these methods lack the conceptual basis to broadly visualize the level of risk over all phases of a project. This study suggests an efficient, yet simple risk-integrated total index to successfully assess the risk levels of overseas construction projects. To this end, this paper first investigates the life cycles and key processes of decision-making for a given project and then derives formulas to represent the total risk index (TRI) along the key decision-making processes. In addition, the study examines the relationships between TRI and performance levels based on the analysis of 126 real-world project samples. Validations using the proposed TRI showed a high correlation to project performance, signifying the usefulness of the proposed approach for construction firms when investigating the level of risks and key areas for management focus.

Under the current dynamic business environment, the corporate knowledge resources are becoming more complicated and diverse. In order to manage these resources effectively, it is necessary to develop an integrative metaschema which accommodates various characteristics of the resources. From this perspective, this paper proposes an integrative metaschema which can manage three types of knowledge resources: schematic model, hypermedia information, and document file. This metaschema can help store and reuse knowledge in a systematic and consistent way. Furthermore, it can support useful and flexible search logics. To demonstrate the usefulness of the metaschema, a prototype system and a real-life bank case are illustrated.
