For the purpose of turning learners' locus of control into internal-controllable variables, counseling materials were developed, and attribution counseling was given. The counseling effects were practically confirmed by way of teaching and evaluation in the actual classes, and furthermore the efforts to provide learners with successful experiences in learning were repeatedly made. As a result, the conclusions are as follows: 1. The procedure of Individual counseling for learning attribution based on individual standard grades and data of the variable order of merit apparently shows learners that if learners are to try their best in learning, they will surely go far in terms of learning in the near future. 2. The procedure of Individual counseling for teaming attribution based on achievement distribution in individual behavior-oriented fields suggests to learners that how to learn is as important as how much effort they make. Surely enough, learners are required to make more effective and efficient efforts, considering their own learning abilities. 3. With the above 1, 2 procedures involved, learners have attributed locus of causality in achievement to their internal-controllable causes. 4. With preparatory assignments according to learner's abilities provided, even slower learners came to be assured that their constant efforts could give rise to success in learning achievement. 5. Above all, it was confirmed that the learners' struggling attitude might well have a significant correlation with achievement success. The learners who are willing to attribute locus of causality in achievement to their internal-controllable causes or strenuous efforts and intrinsic motivation tend to be convinced that they can address themselves to whatever faces them, so they can set up specific learning goals fit for their abilities. Accordingly, they will bit by bit acquire successful experiences (often called 'Aha' experiences) and in turn, feeling the senses of self-efficacy and self-esteem enough to push their efforts even further, they can grow to form a positive self-concept. With one successful experience after another fed back into learners, they are gradually motivated to bring the oncoming achievement expectation to a higher level. To conclude, it is necessary that instruction leading to internal-controllable attribution should be provided, inducing learners to recognize success and failure in learning achievement as a result of their strenuous efforts.

Although the reward based on group accomplishment in cooperative learning has a merit to emphasize interdependency, it may have some undesirable side effects such as free rider effect and sucker effect. For the purpose of reducing these side effects, this study examined how the adjustment of the reward structure affected the scholastic achievement, the perception of learning environments, and the attitude toward science class by adding individual reward to group reward. We selected 2 classes of sixth grade in an elementary school, and taught on oxygen and carbon dioxide for 13 class hours in cooperative learning strategies. Group reward was applied to one class, and both group and individual rewards were applied to the other class. Analysis of the results indicated that the achievement scores of the students under the group and individual rewards were significantly higher than those under the group reward. In addition, they had more difficulty in science class and felt less satisfied. The upper level students under the group and individual rewards were also found to exhibit more competition. Educational implications were discussed.

There are being a lot of studies for achievement of high speed Dehydration, high-strength and Lightweight of washing machine in the latest washing machine business. It is essential that Press-joining Strength of Spin Drum Seaming division is improved .to attain that target. Generally, we are using Mechanical press-joining by Seaming and T.I.G (Tungsten Inert Gas) welding among part joint method. Mechanical press-joining method that is mainly using for Stainless Steel (STS430) Drum have lots of merit that consumption of energy is low more than welding and production costs cut down and generation of the corrosion is solved by removing weld zone defect and materials having different properties are enable to join without special equipment. But, it is difficult to realize joint strength required at high speed operation because joint strength of mechanical press-joining method is low remarkably in comparison with welding. Also, there are a lot of analysis difficulties and very limited research is under way due to the dynamic factor such as multistage plastic working, elastic recovery, residual stress etc. The results of this study show optimal joining condition for mechanical press-joining by performing lots of tensile joining strength test with various specimen under multi-change of important design factor such as seaming width, bead area and bead depth etc.

Background : In order to cope with changes in the management environment at hospitals, increased interests are drawn in patient foodservice system on Continuous Quality Improvement Activity as the method of approaching a quality food service and effective management. Thus, as a part of this activity, this study was conducted to evaluate job flow improvement that was already performed and the results of that process at the dietetic department of a university hospital, focusing on improving management. Method : On February 15 of 1998. the dietetic department formed a job flow-improvement to decide on the priority of job flow improvement, and prepared specific action strategies and schedule of the priority: after a 5 month process period, job improvement achieved on June 15. 1998. Also, economic achievement of the task was evaluated through labor productivity analysis and cost-benefit analysis. Results : The patient food service system which was managed decentralized at the present hospital was centralized, some steps of the food service process were integrated, and quality of patient food was improved. Also, as a solution of the problems expected when conducting job flow improvement was made on food service equipments and utensils. The result of evaluating the job flow improvement that labor productivity improved by 18.2% compared to before the improvement and the result of the analysis of cost-benefit showed that Benefit-Cost (B/C) ratio was 2.22. showing financial merit on the investment. Conclusions : Continuous Quality Improvement Activity needs to be initiated and conducted in the future in various areas of hospital foodservice system in order to actively adopt to ever changing hospital management environment. In order to achieve this goal, many researches and more efforts need to be put in by people in charge of hospital food service management, and interests and support are needed from hospital policy makers.

Key escrow is a default property that is inherent in identity-based cryptography, where a curious private key generator (PKG) can derive a secret value shared by communicating entities in its domain. Therefore, a dishonest PKG can encrypt and decrypt ciphers or can carry out any attack on the communicating parties. Of course, the escrow property is not completely unwanted but is acceptable in other particular applications. On the other hand, in more civil applications, this key escrow property is undesirable and needs to be removed to provide maximum communication privacy. Therefore, this paper presents an escrow-free identity-based key agreement protocol that is also applicable even in a distinct PKG condition that does not use pairings. The proposed protocol has comparable computational and communicational performance to many other protocols with similar security attributes, of which their security is based on costly bilinear pairings. The protocol's notion was inspired by McCullagh et al. and Chen-Kudla, in regard to escrow-free and multi-PKG key agreement ideas. In particular, the scheme captures perfect forward secrecy and key compromise impersonation resilience, which were lacking in McCullagh et al.'s study, as well as all other desirable security attributes, such as known key secrecy, unknown key-share resilience and no-key control. The merit in the proposed protocol is the achievement of all required security requirements with a relatively lower computational overhead than many other protocols because it precludes pairings.

The purpose of this study was to find the factors affecting the bum out syndrome and its degree in terms of personal, organizational and clients characteristics, and then to find the ways to reduce or eliminate those factors. The 228 doctors and the nurses who worked at the emergency departments in 6 general hospitals with more than 700 beds in Seoul were surveyed from April 15, 2002 for 15 days. A structured self-recording questionnaire was used; the t-test and ANOVA was used to analyse the median difference between the occupation, and multiple regression was employed to find the factors affecting the bum-out syndrome. The summary of this research analysis is as follows : First, of several variables, the highest frequency of the burn-out was the emotional burn-out followed by lack in personal touch toward the patients, decrease in sense of personal achievement. These results indicate that the doctors and nurses in emergency departments experience higher degree of burn-out than the social workers and the nurses who work at other departments in heath care environment as other studies revealed. Second, the analysis of the total burn-out factors showed the lower self respect, younger age, heavier work load, higher dissatisfaction rate toward remuneration and not-so-smooth relationship with the patients and their relatives the higher burn out rate. These variables explained 54% of the total variables. Third, the nurses experienced more burn-out syndrome than the doctors. The degree of self-respect, work pattern, relationship with the clients, age and remuneration were the causes of the burn-out. The doctors recorded lack in personal touch toward the patients more, while the nurses more to emotional exhaustion. The limitations of this research are the subjective answers of the respondents to certain questions and differences in sample numbers of each hospital in which some reservation can be exercised in explaining statistical significance of the data, and generalizing the conclusion. Despite of its limitation, this research has its own merit as an unpreceded research in this field, and provision of the basic materials to prevent and find causes of the burn-out syndrome among the doctors and nurses in the emergency departments.
