This article reviewed the research on factors associated with marital quality and stability. Three major categories of factors were described, including background and context, individual traits and behaviors, and couple interactional processes. This review highlighted findings from cross-sectional and longitudinal studies of the prediction of marital quality and stability. Particular attention was given to marital instruments and procedures that had a solid empirical foundation for understanding the concepts related to measure of marital quality and stability. Also, empirically based intervention programs that had been designed to prevent marital distress and divorce were investigated to figure out the relationship between communication factors and conflict resolution styles. Finally, three theoretical frameworks were drawn from empirical literatures, marital measurment instruments, and programs for marital strength to predict factors associated with the marital quality and stability. Recommendations for future research and implications were described.

Many companies are investing in the development of the PDM(Prodct Data Management) system to improve the productivities of manufacturing since people believe that PDM technology can give a new solution from planning to development. As the requirements of PDM grows, so many industries sped their own budget on developing common requirements and functionalities. In this paper, we describe the framework for a PDM application to promote reuse in a PDM system development area. However, developing the framework is not easy. In this paper, the current state and results of our development are described: 1) the phases of developing our framework, 2) abstruction strategies, 3) programing model based on repository. Although frameworks improve software reuse, frameworks are so large and complex that application developers require to understand framework in order to customize the framework. To support the customization of framework, development environment is developed, also.

Value chain analysis has been applied in various fields, from the time the concept of “value chain” was introduced by Porter in 1985. Several frameworks have emerged and have been used to study individual firms, entire industries, industry clusters, as well as global production networks. The purpose of this paper is to provide a brief review of these frameworks, identify factors that influence the performance of value chains, and suggest areas for future research. Since there is a wide range of value chain literature, this paper focuses on a selective set of earlier works within the value chain model as conceptualized by Porter. The study takes note of the many dimensions and applications of value chain analysis, and shows that value chain analysis is an effective way to examine the interaction among different players in a given industry. The study further points out the shortcomings of the traditional or Porter view of value chain analysis.

Recently, Korea has enacted the Framework Act on Product Safety to allow comprehensive control of product safety accidents. This is a government policy aiming to ensure product safety and customer protection by strengthening the obligation of producers. However, the framework has not yet been completed in Korea. Therefore, this paper deals with improvement assignments and directions by comparing the frameworks of applied in Korea and Japan for ensuring such production safety.

A Discrete Event Dynamic System is a system whose states change in response to the occurrence of events from a predefined event set. A major difficulty in developing analytical results for the systems is the lack of appropriate modeling techniques. This paper proposes the use of Real-time Temporal Logic as a modeling tool for the analysis and control of DEDS. The Real-time Temporal Logic Frameworks is extended with a suitable structure of modeling hard real-time constraints. Modeling rules are developed for several specific situations. It is shown how the graphical model can be translated to a system of linear equations and constraints.

This paper is a review of a 13-year-old policy for university reform in Korea, the Brain Korea 21 Program, based on current theoretical frameworks. Current theoretical frameworks are classified into three groups: micro and macro perspectives on universities and discussion on world-class universities. The overall purpose of BK21 is to bring up high-level scholarship through manpower and achieve several targets of university reform. The program can be evaluated as a success in terms of following a research university model but not the entrepreneurial university model. However, the fact that a 13-year old policy developed under a research university model had features of the entrepreneurial university shows the direction of change that the research university is currently undergoing.

This paper explores a content-based image retrieval framework with relevance feedback based on genetic algorithm (GA). This framework adopts GA to learn the user preferences using the similarity functions defined for all available descriptors. The objective of the GA-based learning methods is to learn the user preferences using the similarity functions and to find a descriptor combination function that best represents the user perception. Experiments were performed to validate the proposed frameworks. The experiments employed the natural image databases and color and texture descriptors to represent the content of database images. The proposed frameworks were compared with the other two relevance feedback methods regarding effectiveness in image retrieval tasks. Experiment results demonstrate the superiority of the proposed method.

The present study addresses the research frameworks and directions in the area of accounting information systems (AIS) by conducting a comprehensive survey of 76 A/S doctoral dissertations published between 1980 and 1990. The central research task is to identify the distinctive features of A/S that distinguish it from other disciplines. The procedure of the survey analysis is as follows. First, the A/S dissertations are categorized according to information systems (IS) and accounting. Then, some representative A/S research areas are documented, based on the IS/accounting domain combinations. The paper also attempts to discover the topical trends, supporting bases, and qualitative aspects of the A/S research. The survey reveals a : 1) the existence of economics as a supporting discipline, 2) the topical trend consistent with the evolution of IS, but restricted by the specific combinations of its parent domains, and 3) the need for intellectual rigor in the A/S research.

This paper concerns about how and why design frameworks for optimization should consider various software development environments such as MATLAB, VB, VBscript, Python, Tcl, PHP, Perl, and JAVA. The frameworks can be utilized by many engineers who have a basic concept about the optimization theory and/or basic knowledge about the computer programming languages. The framework will integrate a number of remote CAE tools, automatically execute them for design optimization, and have the capabilities of post-processing of data such as objective functions, state variables and design variables using a third-party spreadsheet program like Excel. The prototype framework developed in this study will be applied to various examples of optimization problems and show the validity of the proposed method of a framework implemenation.

Hydrogen is the most abundant element in the universe. Although hydrogen can produce three times more energy than gasoline and seven times than coal, the most challenging problem in utilizing hydrogen as energy carrier is its storage problem. In contrast to the liquid hydrocarbon, hydrogen can not be stored or transported easily and safely because of its extremely low boiling point(21K). Recently scientists have made a tremendous achievement in storing hydrogen capacity in solid state materials such as carbon based and metal organic frameworks materials as well as metal hydrides. In this review the author reviewed the status of the hydrogen storage technologies in solid state, the advantages and disadvantages in each category of materials and the future prospects of hydrogen storage.
