It is difficult to assemble independently developed software components because of discrepancies between their interfaces. In order to resolve such problem, we propose a new component model, Active Binding Technology, in which each component has its own independently-defined interface for service request that is revealed in its metadata, instead of passively following the interface of a service-providing component. This model Includes the use of the glue component, an interface mediating place, whose template code is automatically generated by reading in the metadata of the components to be combined. We also propose a runtime framework that holds the pool of component instances, completes the assembly of components in the manner of dependency injection, and performs middleware services and real-time system monitoring through glue components. In order to test the practical value of Active Binding Technology, we have made a tool, which supports the development and assembly of Active Binding components.

The study proposes component models in developing an efficient platform for internet-based structural analysis. Since a structural analysis requires an operation of complicated algorithms, a client-side computation using X-Internet is preferred to a server-side computation to provide a flexible service for multi-users. To compete with the user-friendly interfaces of available commercial analysis programs, a window-based interface using Smart Client was applied. Also, component-based programming was performed with the considerations on reusability and expandability so that active Preparation for future change or modification could be feasible. The components describe the whole system by subdivision and simplification. In the relationship between upper-and lower-level components and also in the relationship between components and objects, a unified interface was used to clearly classify the connection between the libraries. By performing data communication between different types of platforms using XML WebService, a conner-stone of data transfer is proposed for the future integrated CAE. The efficiency of the developed platform has been examined through a sample structural analysis and design on planar truss structures.

The goal of this study is to examine the perceptions of pre-service teachers that directly affect the concepts and ways of the consideration of Earth systems by students studying the water cycle. A concept sketch method was applied to a survey involving 131 pre-service teachers. The survey was designed to analyze the perception of subordinate concepts of Earth systems from the applied components of the water cycle process and to code the applied concepts with components of the water cycle to the subordinate concepts of Earth systems that were the Hydrosphere, the Atmosphere, the Geosphere, and the Biosphere. The survey was designed to examine the perception of the water cycle from the perspective of Earth systems. The recognition by pre-service students was largely confined to components of the atmosphere and the hydrosphere. With regard to the water cycle process, all subjects surveyed recognized precipitation, and most of those expressed recognition of evaporation and condensation. Many of them recognized the surface flow, while they scarcely expressed knowledge of the underground flow.

The purpose of the study was to divide social commerce websites' information into components of product, price, service, and seller information, and to systematically analyze each component of information. A content analysis was used as a research methodology, and 100 webpages from social commerce websites were analyzed. As results, the social commerce websites provided basic information (front view, fabric contents, country of origin, care, color, size) for product information and emphasized price information, including discount rates, sales dues, product quantity, and the amount of products sold. They basically provided expected delivery date, delivery company, Q&A, and return/refund service for service information. In addition, they basically presented brand logo and brand name but need to add information about brand concepts, history and volume as seller information. This study suggested diverse theoretical and practical implications of social commerce information.

This paper proposes strain-based acceptance criteria for assessing plastic instability of the safety class 1 nuclear components made of ferritic steel during level D service loads. The strain-based criteria were proposed with two approaches: (1) a section average approach and (2) a critical location approach. Both approaches were based on the damage initiation point corresponding to the maximum load-carrying capability point instead of the fracture point via tensile tests and finite element analysis (FEA) for the notched specimen under uni-axial tensile loading. The two proposed criteria were reviewed from the viewpoint of design practice and philosophy to select a more appropriate criterion. As a result of the review, it was found that the section average approach is more appropriate than the critical location approach from the viewpoint of design practice and philosophy. Finally, the criterion based on the section average approach was applied to a simplified reactor pressure vessel (RPV) outlet nozzle subject to SSE loads. The application shows that the strain-based acceptance criteria can consider cumulative damages caused by the sequential loads unlike the stress-based acceptance criteria and can reduce the overconservatism of the stress-based acceptance criteria, which often occurs for level D service loads.

Service-oriented computing systems have been issued by their properties of reducing software development time and effort by reusing functional service units. The reusability of services can effectively promote through loose coupling between services. But strong associations of object-oriented systems such as inheritance and aggregation create a rather tight coupling between objects. The component-based systems without inheritance and aggregation create a loose coupling between components. Thus components provide service realization at runtime using the functionality provided by their interfaces. Therefore legacy component-based systems need to have service-oriented computing concept in order to support functional service units efficiently. Also, conventional methods for service-oriented computing system have not suggested the clear classification of service layers, the clear service identification guideline introducing service layers and a service mapping method between serviceces of each layer. Therefore we suggest the service classification and the identification guideline of business view and implementation view introducing layers and propose a mapping between two views. That is, we research service layers, service identification, diversified service sizes and a service mapping method between services of each layer. This can be applied to legacy component-based system to extend to the service-oriented computing system.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

This paper proposes a bridge model for data exchange and service invocation between OPRoS and ROS platforms, shows the validity of the proposed model via applications, and compares the proposed model with the OPRoS platform and the ROS platform using performance measures such as data exchange time and service response time. The proposed model operates independently of OPRoS and ROS Platforms using its configuration file with mapping information among the OPRoS data/service port and the ROS topic/service. The configuration file makes easy connections between OPRoS data/service and ROS topic/service without changing the source code of the platform and components.

Service-Learning pedagogy includes community service and reflection as main components. Students can learn integration and application of knowledge beyond specific fields through experiences and reflection. The purpose of family and Consumer Sciences Education is related to connect theory and practice to improve individual, family, and community life. The curriculum focuses not only on content mastery in subjects, but also application of that knowledge to the real lives of students. Considering the purpose of service-learning as integration and application of knowledge, service- learning pedagogy can contribute to rethink family and Consumer Sciences Education. Reflection as a key component is examined for service-learning pedagogy. Exploring a deeper meaning of reflection in aspects of community connection, critical thinking, and transformative learning would extend the value of it and provide implications for implementing reflection in service-learning pedagogy in Family and Consumer Sciences Education.
