Purpose: This study was done to develop and implement the Nursing KMS (knowledge management system) in order to improve knowledge sharing and creation among clinical nurses in outpatient departments. Methods: This study was a methodological research using the 'System Development Life Cycle': consisting of planning, analyzing, design, implementation, and evaluation. Quality Function Deployment (QFD) was applied to establish nurse requirements and to identify important design requirements. Participants were 32 nurses and for evaluation data were collected pre and post intervention at K Hospital in Seoul, a tertiary hospital with over 1,000 beds. Results: The Nursing KMS was built using a Linux-based operating system, Oracle DBMS, and Java 1.6 web programming tools. The system was implemented as a sub-system of the hospital information system. There was statistically significant differences in the sharing of knowledge but creating of knowledge was no statistically meaningful difference observed. In terms of satisfaction with the system, system efficiency ranked first followed by system convenience, information suitability and information usefulness. Conclusion: The results indicate that the use of Nursing KMS increases nurses' knowledge sharing and can contribute to increased quality of nursing knowledge and provide more opportunities for nurses to gain expertise from knowledge shared among nurses.

This study investigates determinants of talent retention in textile and garment companies located in Vietnam's Binh Duong province to propose feasible actions for their sustainable development in the current context of competition on the labor market. This study uses self-completed questionnaires to collect data which are then analysed with statistical methods including scale reliability, exploratory factor analysis, and multiple linear regression. Specifically, results from an official survey of 129 people who are regarded as talents in related companies show that there are ten determinants, ranked in descending order of their importance, including: working environment; training and promotion opportunities; salary and benefits; personal loyalty; relationship with colleagues; nature of work; organizational recognition; type of ownership; relationship with superiors; and working experience. Moreover, it is also found that foreign companies are better in retaining their talents than private domestic ones. These findings suggest that, depending on their available resources, organizations need to focus on some of these factors to improve their talent retention; among them, it is critical to provide creative space or create conductive working environment by providing talents with proper tools and equipment for them to feel excited with their work and get things done in an optimal, efficient and effective manner.

The recycling cell formation problem means that disposal products me classified into recycling part families using group technology in their end of life phase. Disposal products have the uncertainties of product status by usage influences during product use phase and recycling cells are formed design, process and usage attributes. In order to treat the uncertainties, fuzzy set theory and fuzzy logic-based neural network model are applied to recycling cell formation problem far disposal products. In this paper, a heuristic approach fuzzy ART neural network is suggested. The modified fuzzy ART neural network is shown that it has a great efficiency and give an extension for systematically generating alternative solutions in the recycling cell formation problem. We present the results of this approach applied to disposal refrigerators and the comparison of performances between other algorithms. This paper introduced a procedure which integrates economic and environmental factors into the disassembly of disposal products for recycling in recycling cells. A qualitative method of disassembly analysis is developed and its ai is to improve the efficiency of the disassembly and to generated an optimal disassembly which maximize profits and minimize environmental impact. Three criteria established to reduce the search space and facilitate recycling opportunities.

As today's business environment has become more and more competitive, forward as well as backward flows of products among members belonging to a supply chain have been increased. The backward flows of products, which are common in most industries, result from increasing amount of products that are returned, recalled, or need to be repaired. Effective management for the backward flows of products has become an important issue for businesses because of opportunities for simultaneously enhancing profitability and customer satisfaction from returned products. Since third party logistics service providers (3PLs) are playing an important role in reverse logistics operations, they should perform two simultaneous logistics operations for a number of different clients who want to improve their logistics operations for both forward and reverse flows. In this case, distribution networks have been independently designed with respect to either forward or backward flows so far. This paper proposes a mixed integer programming model for the design of network integrating both forward and reverse logistics. Since the network design problem belongs to a class of NP-hard problems, we present an efficient heuristic algorithm based on genetic algorithm (GA), of which the performance is compared to the lower bound by Lagrangian relaxation. Finally, the validity of proposed algorithm is tested using numerical examples.

This paper considers mobility control to improve packet delivery in delay-tolerant networks (DTNs) under group mobility. Based on the group structure in group mobility, we propose two mobility control techniques; group formation enforcement and group purposeful movement. Both techniques can be used to increase the contact opportunities between groups by extending the group's reachability. In addition, they can be easily integrated into some existing DTN routing schemes under group mobility to effectively expedite the packet delivery. This paper is divided into 2 parts. First, we study how our proposed mobility control schemes reduce the packet delivery delay in DTNs by integrating them into one simple routing scheme called group-epidemic routing (G-ER). For each scheme, we analytically derive the cumulative density function of the packet delivery delay to show how it can effectively reduce the packet delivery delay. Then, based on our second proposed technique, the group purposeful movement, we design a new DTN routing scheme, called purposeful movement assisted routing (PMAR), to further reduce the packet delay. Extensive simulations in NS2 have been conducted to show the significant improvement of PMAR over G-ER under different practical network conditions.

This work firstly aims to analyse how the policy makers had been able to sort out the two policy issues, 'how did the MOST establish the inter-departmental project' and 'why did the MOST give a legal power to the private experts', in the process of policy making for Highly Advanced National(HAN) project, called G7 Project, which had been implemented for 10 years in 1990s. Then, this will discuss the policy implications available to the similar policy areas in the future. The result shows that the agenda setting of the G7 Project, one of the successful national R&D projects in Korea, had been initiated by a few leaders who had have the perspective of pioneer. In addition, this explains that private experts had more played than civil servant did in the process of policy formation, which had been backed up by the R&D plannin4g system then introduced in R&D management process for the frist time. This case study will provide policy makers with the opportunities to remind 'the necessities of the policy management by the system not actors', 'more effective management of distribution policy' and 'the better role of related experts in the policy making process'. Also, above issues will make both the practitioners and the researchers again consider how to improve the rationality and effectiveness of the policy making process in the field of science and technology.

Lately, there is a worldwide boom for start-ups. This trends has led to develop many policies for entrepreneurship in Korea, which focused on college education. Also, as the forth industrial revolution knows no borders, demands of software early education are expanding in line with strong interests in IT (Information Technology). Information technology is now an essential competency for all professionals who need creative thinking. And entrepreneurs are a representative job that requires creative thinking. This study suggests IT competencies-IT planning competencies (ITPC) and IT development competencies (ITDC)-as a core factor of the entrepreneurial intention. This paper is to study the relationship between IT competencies and entrepreneurial Intention. So we investigated IT competence and entrepreneurial intention in university students with a questionnaire. The results of this empirical study can be summarized as follows. First, IT planning competencies have positive influence on entrepreneurial attitude and intention. But IT development competencies do not influence directly on entrepreneurial intention. Second, entrepreneurial attitude have mediating effects in the relationship between IT planning competencies and entrepreneurial intention. So, we need to develop good contents related to the IT planning capabilities when organizing training programs in start-up course. In order to improve the quality of entrepreneurship education, it will be necessary to develop educational contents that can have a broad perspective for understanding the trends of technology convergence and creating opportunities.
