  • As a representative reuse paradigm, the theme of service-oriented Paradigm (SOC) is largely centered on publishing and subscribing reusable services. Here, SOC is the term including service oriented architecture and cloud computing. Service providers can produce high profits with reusable services, and service consumers can develop their applications with less time and effort by reusing the services. Design Patterns (DP) is a set of reusable methods to resolve commonly occurring design problems and to provide design structures to deal with the problems by following open/close princples. However, since DPs are mainly proposed for building object-oriented systems and there are distinguishable differences between object-oriented paradigm and SOC, it is challenging to apply the DPs to SOC design problems. Hence, DPs need to be customized by considering the two aspects; for service providers to design services which are highly reusable and reflect their unique characteristics and for service consumers to develop their target applications by reusing and customizing services as soon as possible. Therefore, we propose a set of DPs that are customized to SOC. With the proposed DPs, we believe that service provider can effectively develop highly reusable services, and service consumers can efficiently adapt services for their applications.

  • This was designed to identify the relationship of perceived stress, ways of coping, and stress response in student nurses. The subjects of this study were 320 student nurses from two universities and three junior colleges located in Seoul. The data were collected from November 28 to December 10, 1997 by a questionnaire survey method. The instruments for this study were the perceived stress scale developed by Levenstein(1993), ways of coping scale developed by lazarus & Folkman (1984), and the stress response scale developed by Choi(1991). The data were analyzed by SAS program, using descriptive statistics, Pearson correlation coefficient, and ANOVA. The results are summarized as follows : 1. The mean score for the level of perceived stress was 2.55. 2. The mean score for the level of problem oriented coping was 1.61 and the mean score for the level of emotional oriented coping was 1.37. 3. The mean score for the level of stress response was 3.74. Stress was classified into nine factors and the order of scoring for the most frequent was ; assignments(3.98), as a nurse(3.97), interpersonal relationship(3.88). 4. The relationship between perceived stress and stress response revealed a positive significant correlation(r=0.23, p=0.0001) 5. The relationship between emotional oriented coping and stress response revealed a positive significant correlation(r=0.22, p=0.0001). 6. The relationship between perceived stress and emotional oriented coping revealed a positive significant correlation(r=0.13, p=0.020). In conclusion, this study revealed that the level of perceived stress and ways of coping were important factors influencing the stress response of student nurses. Therefore, in consideration of perceived stress, ways of coping should be included in the development of a stress management program for student nurses. Further research with an expanded area and subjects is recommended.

  • The students who learn the computer languages think it very difficult to program using the text-based programming languages and also to learn the object-oriented programming. Therefore, we introduce the object-oriented visual programming into the programming education. And, to solve the this problem in the programming education, in this paper, we introduce the UML to support the object-oriented modeling and to teach the students using the LabVIEW OOP that supports the object-oriented visual programming. And, we propose to apply it on the embedded programming education. Also, we analyze the educational effect of the proposed education methodology of programming based on the student survey.

  • The manufacturing system has been changed from labored manual process system, which is managed and operated by managers and operators, to CIMS(Computer Integrated Manufacturing System) for integration of manufacturing, research, development and consumption in the age of diverse customer's needs[6]. However, because it involves the hierarchical system composed of many sub-systems interface and its installation & setup cost is very expensive, CIMS has many difficulties in constructing the durable optimal system that is able to adapt to rapid in-outer circumstance change. So, HMS(Holonic Manufacturing System), the new conceptual manufacturing system having the self-problem-solving and self-organization[11], is instructed to solve these difficulties that it has in these days. The system flexibility in the HMS is able to be ensured, with the integration of human's strong points into mechatronics manufacturing system to reduce interference among sub-systems. In this paper, the manufacturing process rationalization and integration of the assembly line in an automobile industry, has lots of problems in efficiency and productivity, has been studied in an early stage of converting the present state of process system to HMS, which is human-oriented processing system, to improve the line efficiency, system productivity and reliability by using human capability effectively. This paper is derived into the human-oriented & object-oriented holons settlement of the shop floor system composed of processing, assembly and material handling system for the future holonic manufacturing system, which is going to be computer supported control system.

  • Complex scheduling problems are related to planning, scheduling, constraint satisfaction problems, object-oriented concepts, and agent systems. Human preference-driven scheduling technique was to solve complex scheduling problems using constraint satisfaction problems and object-oriented concepts. We have tried to apply human preference-driven scheduling technique to reservation problems. For customer's satisfaction, we have considered customer's preferences in the reservation scheduling. The technique of reservation scheduling proposed in this thesis is based on object-oriented concepts. 1'o consider the over all satisfaction, the events of every object are alloted to the board along its priority. Constraints to reservation scheduling are classified to global and local. The definition of board and information of every event are global constraints and the preferences to object's board slots are local constraints. We have applied look-ahead technology to reservation scheduling in order to minimize backtracking not to fail the allotment of events.

  • In order to cultivate talented people who have problem solving ability due to computational thinking according to the trend of the fourth industrial revolution, each university is actively promoting software education. This study suggests that understanding-oriented SW curriculum is needed for non-majors students to improve computational thinking. In order to achieve the purpose of the study, this study designed the basic education program based on the understanding of the SW with the backward design model. The SW Basic Education Program was applied to 15 weeks of instruction and conducted three surveys. The positive effects of the understanding-oriented SW basic education on the computational thinking efficacy and the computer perception were verified. In addition, it was found that the understanding-oriented computational thinking and programming education are effective when they are linked to one process. It is expected that understanding-based SW based education, which uses the backward design model, can be applied as one of the efficient ways to improve computational thinking in the education field.
