이 연구의 목적은 대학의 온라인 수업에 대한 대학의 운영 및 시스템지원이 학습실재감을 매개로 학습참여도에 미치는 영향을 분석하고 구성요인들 간의 구조적 관계를 탐색하는 것이다. 연구목적을 달성하기 위해 온라인수업으로 이루어지는 공통교양과목 중 '대학영어2' 수강생 135명을 대상으로 구조방정식 모형의 확인적 요인분석을 통해 연구모형의 적합도 분석과 경로구조 분석을 실시했다. 연구결과, 첫째, 온라인 수업환경에 대한 대학의 운영지원이 학습자의 학습실재감에 정적인 영향을 치는 것으로 나타났다. 둘째, 온라인 수업환경에 대한 대학의 운영지원이 학습실재감을 완전매개하여 학습참여도에 긍정적 영향을 미치는 것으로 나타났다. 본 연구는 대학의 온라인 수업에서 환경특성 요인인 온라인 수업에 대한 지원, 학습자 특성 요인으로 학습실재감, 학습참여도간의 구조적 관계를 규명하여 온라인 학습장면에서 학습참여도에 대한 이해의 폭을 넓히고 교수·학습 설계에 고려해야 하는 시사점을 제시해 주었다는 점에서 연구의 의의를 지닌다.

This paper presents an integrated object-oriented database approach for managing the evolution of products in agile manufacturing environments, Schema evolution modification facilities are provided to support full potential versioning of type definitions. All of the possible versions for a composite product are not explicitly represented to avoid version proliferation. However, valid configurations of any composite products can be provided to comply with customer demands, The attributes of composite products are classified in order to provide well-defined representation scheme for composite products and to be exploited in version control. The attributes are partitioned into composite-related and non composite-related categories. Composite-related attributes consist of subproducts and description ones. Subproducts attributes represent physical constituents of a composite product. Description attributes represent external features, assembling, and correspondence property. Interface attributes are introduced for managing configurability and version propagation. Version derivations due to the changes to the interface attributes are propagated toward the product composition hierarchy, The validity of configurations of composite products is checked by using configurability maps. Instance objects which represent the actual product instances are stored and manipulated in the database in order to support traceability during product life cycle.

The purpose of this study is to analyze the effects of job stress on job attitude among nurse practitioners, determine moderating effects of perceived organizational support in this process, and provide preliminary data to devise a scheme for managing job attitude effectively in nursing manpower. The research model was composed of 7 sub-variables of job stress, which was a independent variable; job attitude, which was a dependent variable, was divided into job satisfaction and organizational commitment; and variables of moderating effects included perceived organizational support. The data for empirical analysis of the model were collected from 300 nurses working in one university hospital and two general hospitals in Busan by using structured self-administered questionnaires. The main results of empirical analysis were as follows: Perceived organizational support was effective in preventing job stress from worsening job attitude. Moderating effects of perceived organizational support were found to exist in relations between job stress and organizational commitment. These results imply that a sense of organizational support has both direct and moderating effects on job attitude and can be a good means of managing job attitude.

Purpose: This study was attempted and completed in order to settle down and qualitatively improve web-based nursing education by evaluating effect and managing strategy of tutor. Method: The development of tutor's managing strategy was based on "The Self-regulated Learning" and "The supportive Learning", then it was applied to 79 learners in one of the cyber-learning centers. After applying the tutor's managing strategy, self-regulated learning scale, attitude for school, preference for computer and academic achievement were evaluated. The development of tutor's managing strategy for web-based nursing education are consisted of participation promotion, psychological support and motivation, recognition and promotion strategy of learning activity, management strategy of evaluating stage. Result: The levels of learner's self-regulated learning, recognition, behavior, attitude on the school and learning achievement were meaningfully increased in statistics after applying for the managing strategy of tutor. The motivation level and learning participation kept high scores from the beginning with no significant statistical changes. Conclusion: It is required to develop an educational program for cultivating well-educated tutors in order to help the effective learning process of nurses based on understanding characteristics of learners.

Due to the rapid growth of Internet, means of communication with customers in a traditional customer support environment such as telephone calls are being replaced by mainly e-mail in a Web-based customer support system. Although such a Web-based support is efficient and promises potential benefits for firms, including reduced transaction costs, reduced time, and high quality of support, there are some difficulties associated with responding to many types of customer's inbound e-mails appropriately. As many types of e-mail are received, considerable attention is being paid to methods for increasing the efficiency of managing and responding e-mails. This research proposes an intelligent system for managing customer's inbound e-mails in organizations by applying case based reasoning technique for responding to various customers' inbound e-mails more effectively. In this approach, a case is represented as a frame-typed data structure corresponding to an inbound e-mail, keywords, and its reply e-mail. In the retrieval procedure, keywords and affinity set is developed to index a case, and then the case is represented as a vector, a case vector. Also, cosines value is calculated to measure the similarity between a new inbound e-mail and the cases in the case base. In the adaptation procedure, we provide several adaptation strategies to adapt and modify the retrieved case. The strategies guide to make an outbound e-mail using product databases, databases for customer support, etc. Additionally, the Web-based system architecture is proposed to implement our methodology. The proposed methodology and system will be helpful for developing more efficient Web-based customer support.

Based on the Financial Management Information Systems (FMIS) variables and supporting arenas, the current study aims to highlight the importance of FMIS in supporting organizations to achieve organizational excellence (Managing Liabilities, Support Decision Making, Cost Efficiency, Financial Quality, and Security). A quantitative approach was utilized by adopting a questionnaire as a tool. A convenient sample of (249) individuals from different Kuwaiti SMEs answered the questionnaire. SPSS v. 26 was used to analyze gathered data. The study's findings revealed that FMIS has a significant impact on organizational trials to achieve organizational excellence. This impact was most noticeable on the level of cost-efficiency, with an R-value of 0.583, followed by a positive impact on security, with an R-value of 0.453. Based on the results, it can be widely generalized that FMIS can help the organization reach organizational excellence through managing its financial affairs. As a result, the study recommends paying more attention to the quality of data presented to FMIS, keeping in mind that human errors in data entry might result in incorrect and malfunctioned data, even if it is processed by FMIS. FMIS also improves the ability of an organization to schedule financial information, such as obligations, receivables, debts, payments, and expenses.

This study is about apartment greening to improve urban environment. To achieve this, questionnaires concerning the planter preferences were distributed. To improve perpendicular greening methods for apartments, MOCT (The Ministry of Construction and Transportation) reformed the law to obligate constructors to make apartment planters in June, 2000. But apartment residents take negative attitudes to making green space. It is difficult to manage the planters as well, so it is necessary that the point at making green spaces at apartments be scrutinized through questionnaires and an active method for making and managing the planter be made. The results show that apartment residents are reluctant to pay the expenses for planting and managing planters and have negative attitudes about plant purchases. If planting and managing of simplified planters are continually entrusted to residents, even vertical landscapes will be affected by illegal diversion and negligence as a result. Therefore, support from governments and local administrations are needed and legal obligation should be imposed on construction companies to install irrigation facilities.
