This paper presents a new interactive procedure for multiple objective linear programming problem (MOLP). In practical multiple objective linear programming applications, there is usually no need for the decision maker to consider solutions which are not efficient. Therefore, the interactive procedure presented here searches only among efficient solutions and terminates with a solution that is guaranteed to be efficient. It also can converge to nonextreme efficient final solutions rather than being restricted to only extreme efficient points of the feasible set. The procedure does not require sophisticated judgements or inputs from the decision maker. One of the most attractive features of the procedure however, is that the method allows the DM to examine the efficient faces it finds. As iteration goes, the DM can explore a wide variety of efficient faces rather than efficient faces confined to only certain subregion of the feasible set of problem MOLP since the efficient faces that the procedure finds need not be adjacent. This helps the DM explore the nature of the efficient set of problem MOLP and also helps the DM have confidence with a final solution. For these reasons, I feel that the procedure offer significant promise in solving multiple objective linear programs rapidly and in a satisfying manner to the DM.

Purpose: This study was conducted to evaluate the learning outcomes of simulation-based practice on emergency care for patients with dyspnea in nursing students. Methods: One group pre-post experimental design with 28 nursing students was used. Simulation-based practice on the basis of SimMan Human Patient Simulator including academic lectures, simulation lab exercises and debriefing was applied for four and half hours. The learning outcomes were assessed by measuring knowledge, critical thinking, problem solving process of cognitive skills, self-confidence and learning attitudes of affective domain. Furthermore, self reported clinical performance ability of psychomotor skills was examined. Results: After the completion of simulation-based practice, there was a significant increase in the mean of following measured variables: knowledge, critical thinking, problem solving process of cognitive skills, self-confidence, learning attitudes of affective domain and clinical performance ability of psychomotor skills. Significant positive relationships were found among learning outcome measurement variables. Conclusion: Simulation-based practice is an effective method to improve cognitive skills, affective domain and psychomotor skills of nursing students. Hence, Simulation-based practice should be applied for improving current limited emergency care training for nursing students and enhancing students' competency in clinical situations.

This is a quasi-experimental study involving one group design with pretest and posttest for evaluation of an effectiveness of an emergent care management simulation education among senior nursing students according to their learning styles. Participants were 58 senior nursing students. Learning style and educational effectiveness (critical thinking disposition, problem solving process, cooperation, satisfaction with learning, and self-confidence) were measured. Learning styles of senior nursing students were converger 46.6%, assimilator 34.5%, accommodator 15.5%, and diverger 3.4%. Critical thinking disposition, problem solving process, cooperation, and self-confidence were significantly enhanced by an emergent care management simulation education. Otherwise, educational effectiveness according to learning styles were not significantly different. Based on the results, devising stratagem to maximize an educational effectiveness will be needed trough re-evaluation of relationship between learning styles and effectiveness of a simulation education.

Purpose: The purpose of this study was to explore EMT-paramedic students' experience of simulation education and analyze the confidence before and after education, learning attitude and course evaluation. Method: Research survey was conducted on 38 EMT-paramedic students during November, 2011 and EMT-paramedic students' experience of simulation education was analyzed after applying head, spinal, and chest injury scenario. The confidence before and after education, learning attitude and course evaluation in gender were analyzed by Mann-Whitny U test and the difference of confidence before and after education was analyzed by Wilcoxon signed rank test and learning attitude & course evaluation were analyzed by evaluating frequency, percentage, mean, standard deviation by using SPSS WIN 17.0 program. Results: 1. Students experienced various advantages such as increasing interest and self-reflection on learning, critical thinking ability, and EMT-paramedic-role experience and recognition of importance of teamwork. Students also pointed out disadvantages such as gap between real situation and simulation, limit of time and equipments, and burden of demonstration. 2. The confidence between before and after education, learning attitude and course evaluation in gender were not significant different statistically. 3. Confidence mean score elevated from 5.53(before education) to 5.87(after education), but the difference in their confidence did not show significant difference statistically. 4. Total mean score in learning attitude after simulation education was 3.70 out of 5.00, which is considerably very high. 5. Total mean score in course evaluation was 3.89 with score of 3.83 in evaluation in learning environment and 3.99 in evaluation of debriefing. Conclusion: The finding of this study demonstrate that the simulation education can provide a safe and repetitive practice environment, improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective EMT-paramedic education strategy.

This study examined the effect of rope play through forest experience on children's self-confidence. Empirical analysis through the experimental design was carried out on an experimental group of 15 (seven male and eight female children) and a control group of 15 (nine male and six female children). Analysis of covariance (ANCOVA) for the effect between the experimental and control groups after the experimental treatment showed that the mean of the experimental group was significantly higher than that of the control group (F=357.350, p<.001). Rope play through forest experience has a statistically significant effect on the children's self-confidence. Consequently, rope play through forest experience between peers is a beneficial experience that helps improve children's self-confidence. Furthermore, it is a positive play activity to help them with a passive character boost to their self-confidence through cooperation between peers.

The purpose of this study was to investigate the effects of case-based learning about infants and toddlers on healthcare department students, using a video in an emergency care environment. A total of 57 students from a healthcare department of D university in J city were enrolled. They were divided into two groups: The experimental group (n=29) and the control group (n=28). This study is pre-post designed with a non-equivalent control group. The experimental group received a 1-week education for a duration of 3 weeks (3 sessions in total) with 180 minutes per session. The control group received a traditional curriculum of lecture. Before and after the education, we measured the knowledge and skill confidence of emergency care toward infants and toddlers, the academic self-efficacy, and problem solving ability. Data collection and intervention were carried out from November to December of 2014. Data were analyzed with x2-test, paired t-test, unpaired t-test with SPSS version 20.0 Program. The experimental group showed a significantly higher improvement of skill confidence of emergency care toward infants and toddlers (P<001), as well as preferred task difficulty among sub-items of academic self-efficacy (p=.029), approach avoidance style (P=.001), and problem solving confidence (p=.040) among sub-items of problem solving ability on preference compared with the control group. In this study, a case-based learning was verified to be an effective teaching method to enhance professional competency of healthcare department students. The findings from this study suggest that a case-based learning using various educational contents should be developed, expanded, and carried out to promote better learning.
