Aspect-Oriented Software Development is new software development method. It has many advantages related to software performance, maintenance and repair. Also it offers modularization method to a existing programming language for secondary function such as security and fault tolerance. But the present problem is that we have to use new aspect-oriented programming language. Further more when we apply Aspect to legacy system, we have to recompile the source code in order to build software system based on AOSD. In this paper, we propose and design Connector that can be composed with Aspect in legacy system dynamically. To elaborate this work, we use the information of operations about Core and Aspect, and the information of pointcut described with XML. We validate that the proposed Connector has features such as no need of new compiler, no recompilation and no modification of legacy system through case study.

In the domestic game development field, game system planning is the work that game designers design the gameplay mechanics system to satisfy the game concepts in the perspective of creative design by data structural methods. But the programmers work to design the game system based on the results of the game system planning in the perspective of engineering design by object-oriented methods. This work process is a high risky way for high occurring probability of communication errors between the game designers and programmers, and mismatching errors in their work results. In this study, we propose an object-oriented design method of game system for the game designers in order to resolve this problem. The proposed method is a customized one of GRAPPLE object-oriented SW development guidelines to suit the game system planning. To investigate the effectiveness of the proposed planning method for the game designers, we carried out a survey targeting 10 game system designers working in the domestic game industry. The survey results show that the necessity and effectiveness of the proposed method is "a little over" for almost the game designers.

This study explores the effectiveness of employment-oriented welfare state by analyzing the mediating role of employment rate on the relationship between public welfare effort and fiscal soundness. Notably, this study considers the quality of employment into the analysis: part-time work, involuntary part-time work and low-wage work in analysis. The data sample consists of 18 OECD countries which initiated employment-oriented welfare strategy after the crisis of welfare state. An analysis was conduct based on Baron & Kenny(1986)'s method and panel two-stage model to handle the endogeneity problem. The results show that while the high level of public welfare effort negatively affects the fiscal soundness if it contributes to boosting employment rates, it has positive effects on the fiscal soundness. However, when the incidence of involuntary part-time employment and low-wage employment is high, the mediating impact of employment rate on the fiscal soundness disappears. This study argues that unless the quality of employment is taken into consideration, the positive effect of employment-oriented welfare state strategy to improve the fiscal soundness is not fully guaranteed.

Recent demands from construction industry have emphasized the capability for graduates to have improved skills both technical and non-technical such as problem solving, interpersonal communication. To satisfy these demands, problem-based learning that is an instructional method characterized by the use of real world problem has been adopted and has proven its effectiveness various disciplines. However, in spite of the importance of field senses and dealing with real problem, construction engineering education has generally focused on traditional lecture-oriented course. In order to improve limitations of current construction education and to satisfy recent demands from construction industry, this paper proposes a new educational approach that is Failure-Based Learning for using combination of the procedural characteristics of the problem-based learning theory in construction technology education utilizing failure information that has the educational value in the construction area by reinterpreting characteristics of construction industry and construction failure information. The major results of this study are summarized as follows. 1) Educational effect of problem-based learning methodology and limitation of application in construction area 2) The educational value of the information on construction failure and limitation in application of the information in construction sector 3) Anticipated effect from application of the failure-based learning 4) Development and application of the failure-based learning conceptual model.

An agent is an abstract unit for problem solving in the field of distributed artificial intelligence, and an agent-based system is designed and implemented based on the definition of agent as its central concept. Agent modeling is advantageous to abstraction, disintegration and structuring for describing complex system, so its application is increased in various areas including air traffic control, power transmission, e-commerce and medicine. There is no agreed definition of agent but agents have common points as follows: autonomy, reactivity, pro-activeness and cooperation. An agent-oriented modeling is an approach of a concept different form existing object-oriented modeling. This study proposed the agent application for E-Beam manufacturing system. To evaluate the performance of the proposed process design, we used the JADE library. The JADE toolkit provides a FIPA-compliant agent platform and a package to develp Java agents. It provides a basic set of functionalities that are regarded as essential for an autonomous agent architecture.

Purpose: The purpose of this study was to explore the predictors of cardiovascular risk factors among type 2 diabetic patients. Method: Data were collected from November, 2003 to June, 2004 using a physiological index and questionnaires. Patients(N=159) aged 40 and above were conveniently recruited from health care centers in B city. Data were analyzed with descriptive statistics, Pearson correlation and stepwise multiple regression using SPSS WIN 10.0 program. Results: The cardiovascular risk factors were negatively related with female gender, household monthly income, educational experience about diabetes, physical activity, self-care, self-efficacy and problem oriented coping, while positively related with the duration of diabetes, diabetic family history and depression. Self-care, diabetic family history, female gender, monthly household income, self-efficacy, affective-oriented coping and physical activity predicted 41.5% of the variance in cardiovascular risk factors of diabetic patients. Conclusion: According to the findings of this study, we concluded that cardiovascular risk factors of type 2 diabetic patients are related to the modifiable and non-modifiable variables. Self-care, self-efficacy, affective oriented coping, and physical activity were identified as modifiable variables. Intervention programs to increase those variables are warranted to reduce cardiovascular risk factors among type 2 diabetic patients.

Asymmetric rolling, in which the circumferential velocities of the upper and lower rolls are different, can give rise to intense plastic shear strains and in turn shear deformation textures through the sheet thickness. The ideal shear deformation texture of fcc metals can be approximated by the <111> // ND and $\{001\}<110>$ orientations, among which the former improves the deep drawability. The ideal shear deformation texture for bcc metals can be approximated by the Goss $\{110\}<001>\;and\;\{112\}<111>$ orientations, among which the former improves the magnetic permeability along the <100> directions and is the prime orientation in grain oriented silicon steels. The intense shear strains can result in the grain refinement and hence improve mechanical properties. Steel sheets, especially ferritic stainless steel sheets, and aluminum alloy sheets may exhibit an undesirable surface roughening known as ridging or roping, when elongated along RD and TD, respectively. The ridging or roping is caused by differently oriented colonies, which are resulted from the <100> oriented columnar structure in ingots or billets, especially for ferritic stainless steels, that is not easily destroyed by the conventional rolling. The breakdown of columnar structure and the grain refinement can be achieved by asymmetric rolling, resulting in a decrease in the ridging problem.

Social participation of the elderly and the disabled continuously becomes more active due to the improvement of social systems and technological development. Various systems such as intelligence robots and intelligence home systems have been developed to support their social participation, and those systems obviously contribute to the independent lives of the elderly and the disabled. Those systems, however, usually require special hardware, which make them very expensive. Considering the economic difficulties of the users, the problem should be tackled with software-oriented approaches using existing hardware such as laptops. The software should be adapted to users with limited capabilities by enabling them to utilize the system without much knowledge related to computers and also without keyboards and mice. This paper suggests software-oriented approaches to solve those problems with the description of the unified user interface for a special work chair, and introduces an actual development procedure of the program together with real application of related theories.

In the case of developing the real-time system using object-oriented method, k the problem of the timing constraints is certainly considered. we propose the method of modeling the object-oriented real-time system using the OMT methodology and the SDL. And we also present the predictable time table that reflects the constraints of real-time system into dynamic model of OMTs and the predicatable time formula of the sequence, repeat, and parallel routine. The proposed method is applied to the estimate of the maximum process time of the ATMs(Automatic teller machines) and is used to specifying the functional specification for the user interface of the ATMs using the SDL syntax and the object interaction graph.
