This study aimed at inquiring into the basic theory on co-operative education, grasping and analyzing the present situation of the junior health college, the present condition of co-operative education and into problem. and seeking to find a solution to activate the co-operative edcation of the junior health colleges. For this purpose this study compared the co-operative education system in our country with that of foreign countries revolving around the related literature to co-operative education, analyzed it, and the pointed out its problem. And this study classified into the solution of establishing co-operative education system, the solution of consolidating the on-the-spot training system, the solution to activate the co-operative education of the junior health college. First this study suggested three methods as a part of establishing co-operative education system as below. 1. The need to set up the ideology concerning co-operative education. 2. The construction of the advisory committee for co-operative education. 3. The establishment of an agency for co-operative education. And this study suggested nine methods as the method of consolidating the on-the-spot training as below. 1. The execution of the basic research for the on-the-spot training. 2. The reorganization of the existing curriculum into the curriculum the industrial organization requires. 3. The establishing of the system in a closer cooperation with the industrial organization for the on-the-spot training. 4. The participation in solving commonly the problems of the industrial organization and in education. 5. The establishing of the guidance system assuming exclusive charge of the on-the-spot training. 6. The submission of the evaluation sheet for the on-the-spot training. 7. The extension of the period of the on-the-spot training and the reorganization of an educational system. 8. The persistent support for the on-the-spot training at the governmental dimension. 9. The securing of the educational dost spent on the on-the-spot training and the imposition of benefits on the industrial organization.

Energized power transformers in substations make unwelcome noises which propagate to nearby residential areas. As the excessive noise level become a target of public grievance than ever, utilities are seeking solutions to it. This paper introduce a power transformer noise prediction program which can give utilities effective solutions. Once a noise source is given, the program calculates the propagated noise level at certain points. The estimated result is rendered as noise contour map. To validate the accuracy of the program, the predicted noises are compared to measured one in real substations and proven to be acceptable within a margin of 5 percent.

Korea is one of the most advanced countries in terms of nation-wide readiness for conducting complex trade processes in an electronic way. Since various trade processes are well-known for their complexity and cost as well as time consuming characteristics due to required collaborations with involving parties, automation and efficiency are always the main concern of trade-related practitioners. Using information technology can be a possible solution to this problem and Korea has developed the national e-trade infrastructure called "u-Trade Hub." In this paper, we propose the framework to enhance the national integrated e-trade system called "u-Trade Hub," which is ready to be released for commercial use in near future. We propose the framework to upgrade u-Trade Hub in four directions: (1) opening, (2) strengthening community feature, (3) modularization, (4) seeking profitability. In this paper, we study and compare national e-trade environment of other countries such as Singapore and Japan. Then, we analyze and design the enhanced e-trade infrastructure based on Web 2.0.

By committing to a long-term replenishment contract, suppliers can mitigate the pressure to find new customers and afford to charge a discounted price to buyers seeking to lower their purchasing costs. In this paper, we develop an analytical model from buyer's perspective for the contracting process to investigate the buyer-supplier interactions. Based on the developed model, we propose an algorithm to derive optimal strategy for the contract. We consider a system with a single buyer and a supplier in a situation where the buyer's inventory is controlled by (R, S) policy under VMI setting. According to the contract, the supplier should replenish the buyer's inventory up to a fixed level every R times during a specified period. The buyer purchases any deficient amount from a spot market at a higher price. We show by computational experiment that our proposed algorithm finds the global optimum solution.

The tremendous growth in electronic journals made it clear that access would be one of the biggest issues confronting libraries seeking to adopt them. While users must be given the freedom to move seamlessly between electronic and paper journals, the most of university libraries in Korea have not provided a single point access to these yet. This study offers opportunities to improve the convenience which permits integrated access to the thousands of electronic and paper ones. It is suggested that the integrated catalog can be an appropriate solution that allows the one-stop shopping approach to library's entire collection.

Unlike that of most management science methodologies, the focus in systems thinking is not on \\\"solving\\\" problems or seeking an optimal solution. Conventional problem solving does not explicitly consider the context of the problem. This implies that the \\\"hospital financial management problem\\\" could be neatly isolated from its environmental and external factors. System thinking and system archetypes, in contrast, acknowledges the messiness of the world and views a problem in the context of its environment. This is one reason why qualitative variables play an important role in system thinking, as these variables represent conditions or phenomena that cannot be measured or accounted in a strictly quantitative approaches. In this paper we present specific healthcare system archetypes which consider such external influences in the healthcare industry in Australia and observe their behavior over time. behavior over time.

Purpose: The purpose of this study was to explore the experience of workplace violence among intensive care unit nurses. Methods: The participants of this research were twelve registered nurses who work in the intensive care units (ICU) at the hospitals in Seoul and Gyunggido. Data were collected by individual in-depth interviews and analyzed using the phenomenological methodology by Colaizzi. Results: From significant statements, five theme clusters emerged as follow; 1) vulnerable young women to violence, 2) my own reflection was bruised and exhausted, 3) a hopeless everyday, 4) seeking a solution in relation, 5) establishing one's status as a professional nurse. Conclusion: This study provides a profound understanding on the experiences of workplace violence among ICU nurses. The hospitals are suggested to provide a safe environment by developing programs and policies to prevent and cope with hospital workplace violence for ICU nurses.

The rapid development of airlines, has made airports busier and more complicated. The assignment of scheduled to available gates is a major issue for daily airline operations. We consider the over-constrained airport gate assignment problem(AGAP) where the number of flights exceeds the number of available gates, and where the objectives are to minimize the number of ungated flights and the total walking distance or connection times. The procedures used in this project are to create a mathematical model formulation to identify decision variables to identify, constraints and objective functions. In addition, we will consider in the AGAP the size of each gate in the terminal and also the towing process for the aircraft. We will use a greedy algorithm to solve the problem. The greedy algorithm minimizes ungated flights while providing initial feasible solutions that allow flexibility in seeking good solutions, especially in case when flight schedules are dense in time. Experiments conducts give good results.
