Recently, OOM(Object-Oriented Method) access method which begins to apply to software development is emphasizing development cost and time reduction through independent software reuse. But because of planning to the exclusion of the lack of knowledge and expansion or performance for development technology many problems are coming out. Therefore, this thesis suggests Effective Object-Oriented Modeling methods considering the plan for higher productivity enhancement of software in the software development life cycle. Effective Object-Oriented Modeling method includes, methods, Use Case modeling methods, Analysis Modeling methods, Design Modeling methods and others. This thesis suggests Framework model method read in characteristics as follows. First, suggestion about effective object-oriented standard model development, Second, retrenchment of software development or maintenance cost, Third, solution about uncertain problems of projects in line with the application of new technology.

Since the guaranteed service quality(QoS) is spotlighted as a strategic competitive tool to Broadband Convergence Network(BcN) service providers, many scholars have dealt with QoS issues in the BcN environment. However, just a few researchers focus on end-users and most are lean toward service providers or technology itself. In this paper, therefore, we investigated how end-users could measure service quality in the BcN environment, and moreover, proposed the end-user oriented measurement guideline for BcN QoS. Through literature review and two surveys, four QoS dimensions and nineteen measurement items were derived from end-user's perspective. proposed QoS dimension and items would be utilized as meaningful tools for future BcN service.

The aim of this study is to develop a simulation model for analyzing 2D truss structure using Generic Agricultural System Simulator (GASS). Although the truss is simple structure, numerical methods based on matrix analysis are cumbersome and complicated. This study suggests simple and convenient methods to remove calculating steps for whole stiffness matrices. The simulation environment based on independency of object-oriented components on GASS consists of component development and component deploy stages. A component for a truss structure is implemented based on equilibrium equations at nodes. The simulator can analyze truss structures through deploying components with attributes and links. The examples using GASS show intuitive graphical results of the movements of truss nodes.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced, and the Web services and ESB (Enterprise Service Bus) ate also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which is introduced in this paper, will be a good reference for future SOA implementation.

As web environment receives web2.0, producer-oriented services are changing user-oriented. This trend is considered the collective intelligence made by users' knowledge. But in contrast with a change of web, structure of current education is composed of educators as producers. Accordingly, it is difficult to reflect needs of educatees who are real users in education system. So we study online education for advance of its environment which is applied to collective intelligence.

This study explores the types of lifestyle of females living in urban areas, and examines the relationship between the types of lifestyle and the preference for interior design images. The research sample is 301 adult females in Kwangju City, Korea. The sample is divided into two groups by employment status. Based on eight lifestyles by related factors, four major lifestyle types are classified: traditional type, private and sensible type, passive and private type, and environment-oriented and sensible type. The portions of these types are 32.6% of passive and private type, 21.6% of environment-oriented and sensible one, 21.6% of active and sensible one, and 16.6% of traditional one. The research of the lifestyle types reveals that they differ by age, marital status, education, and dwelling types. There are negligible differences among four types in preference for three interior design images.

A competitive automated manufacturing system integrates the various control processes and data used in service of products. design, manufacturing, and, sale. CIM is a way to achieve such integration through computers and computational techniques in manufacturing, planning, and design. Developing effective CIM architectures is hampered by integration problems. The key to resolving these problems lies in a better understanding of manufacturing function and how it is related to other manufacturing functions. Integration of CIM environment requires coordinated solutions to data management problems for individual application system as well as for exchange of data between these applications. This requires a common framework for data management throughout the CIM environment. This paper discusses the design paradigm as a framework for this purpose. Designing an organizational structure to meet those goals invloves 1) analyzing the functions through functional decomposition, 2) developing a data model to coordinate functions. As a result, we propose an object-oriented design methodology for manufacturing information system.

It is an urgent time to give impetus to an ecological understanding of relationship between man and environment and to promote an action to preserve environment. This paper is to examine factors which give influence to environmental education environmental consciousness and environmental behavior of housewives. The subjects of this study are 806 Seoulite housewives. A questionaire is used as the survey method and the statistical methods such as frequency percentage ANOVA multiple regression path analysis have been applied for research. Major findings are summarized as follows: Major findings are summarized as follows: When environmental education program is relatively low differences are shown according to variables of age, education and occupation. Second, when environmental consciousness is high differences are shown according to variables of age education income and housing. Third when environmental behavior is low group difference is shown only according to age. Relative influence to environmental behaviour is shown in the order of spare-life type environmental education environmental consciousness socio-oriented type fashion-oriented type and age difference.

A modular programming approach for simulation/control of turbocharged diesel engines is investigated. The MATLAB/SIMULINK, which provides easy construction of various control modules and handy retrieval of objects, is adopted as a programming environment. The mathematical models for diesel engines are utilized from the literature. The object-oriented modules, which represent mechanical parts or theoretical algorithms for engines, are easily transferable to other application programs in the same environment. The simulation model is applied to a 4 strokes diesel engine. Details of the block diagrams of example modules are demonstrated. Finally, a PI controller and a sliding mode controller are applied to the simulator constructed for a typical turbocharged diesel engine.

Rural policies in Korea have been changed into amenity-oriented ones recently to enhance the quality of life for villigians, which should be supported by the amenity-oriented maintenance system for rural space or environment too. Although so many studies on the classification system of amenity resources had been carried out, few ones which classified them principally by their spatial characteristics had been tried. From the viewpoint mentioned above, this study tried to propose a tentative classification system of amenity resources focussed on their locational characteristics. By the literature review, its draft was prepared, and after 2-round expert checks, the final table determined, which composed of 3-subsystems; green, production and living environment. Through the field application works in two case villages, its practical applicability was ascertained, from which two regarding points were found; public usability of terms and seasonality of amenity resources, especially green ones.
