The purpose of this study was to test the effects of simulation practice education on clinical judgment, self-confidence, and clinical performance ability of nursing student. This study used a one group, pre-post test design. The subject of this study were 45 second grade nursing students who participated in the simulation practice education. Data were collected before and after the simulation practice education using the questionnaire. As a result of this research, the improvements of the clinical judgment, self-confidence, and clinical performance ability were statistically significant. Therefore, the simulation practice education has a positive effect on nursing students in terms of the clinical judgment, self-confidence, and clinical performance ability.

프랑스 CEA 실험장치인 BETHSY 실험설비에서 수행된 부분충수 운전에 대한 실험인 6.9c 실험에 대한 MELCOR 1.8.3 의 평가를 수행하였다. 이 연구는 OECD/NEA 국제공동연구인 ISP-38 로 수행되었다. 평가결과, MELCOR 1.8.3 은 부분충수운전시 잔열제거계통 상실에 대한 예측능력이 있고 원자로 냉각재계통압력, 노심수위 등 전반적으로 거동을 잘 모의하고 있다고 판단되었다. 그러나 민감도 분석에서 도출된 결론에 의하여 상간의 운동량 전달 및 Liquid Entrainment모델에 있어서 개선 필요성이 있는 것으로 평가되었다.

Experimental study was carried out to investigate the structural performance of composite beams with steel fiber concrete and angle. For this purpose, seven specimens composed of two RC beams with or without steel fiber and five composite beams with steel fiber and angle were constructed and tested. All specimens had no web shear reinforcement. Main variables for the specimens were tensile reinforcement ratio and fiber volume fraction. Based on the test results, structural performance such as strength, stiffness, ductility and energy dissipation capacity was evaluated and compared with the predicted strength. The prediction of flexure and shear strength gives a good relationship with the observed strength. The strength, ductility and energy dissipation capacity are increased, as the fiber volume fraction is increased. Meanwhile, high tensile reinforcement ratio resulted in the reduction of ductility and energy dissipation capacity for the composite beams.

This study aims to verity effects of project method on the girl students' task performance ability in the unit of 'Energy and Transportation Technology' of Technology' Home Economics Subject in High schools. The task performance ability are composed of collecting information, performing achievement, planning of solving the task, and performance evaluation. The results of this research conducted for girl students of two classes of H high school located in Gyeong-gi Province are as follows: First, the group with the project method was more effective, in general, in learning ability of performing the tasks of 'Energy and Transportation Technology' than the group with traditional teaching. Second, the group with the project method was more effective than the group with traditional teaching in ability of task performance of subordinate elements of performing tasks in the unit of 'Energy and Transportation Technology', such as collecting information and performing achievement. However, in the fields of another subordinate elements of planning of solving the task and performing evaluation, the degree of effectiveness was unknown. After examining the results of all the cases, it was found that project method was more effective than the traditional teaching method in increasing the performing task abilities of the students in the lesson of 'Energy and Transportation Technology' in high schools.

Purpose. This study was conducted to identify effects of the high fidelity simulation for nursing students. Methods. A non-equivalent quasi-experimental design was used to experimental group (N=43) and control group (N=39) for 8 weeks, 5 times from September 26 to November 9, 2013. Clinical performance was measured by using standardized patients. Critical thinking was measured through the questionnaire and clinical judgement was measured through observation by Lasater's rubric. Results. Clinical performance (F=211.15, p<.001), critical thinking (t=3.00, p<.004) and clinical judgement (t=7.60, p<.001) were significantly higher in experimental group with simulation education program than control group. Conclusion. Simulation education program were effective to improve clinical performance, critical thinking disposition and clinical judgement for nursing students.

This study was conducted to examine the convergence effects of a simulation-based handoff training program on nursing students' handoff performance ability and handoff confidence. A quasi-experimental study of pre and post-experimental design was performed on 104 nursing college students located in P city and A city and the developed simulation-based handoff training program was implemented for 2 weeks from October 30 to November 10, 2017. The collected data were analyzed using the SPSS WIN 21.0 program with x² test, Fisher's exact test, independent t-test, ANCOVA with pretest value as covariate. The experimental group had significantly different handoff Performance Ability in comparison to the control group. The simulation-based handoff training program can be used as an effective handoff training program to enhance the handoff performance ability of nursing students.

Objectives：This study was conducted to investigate the effect of oxygen on attention and memory functions in healthy adolescents. Methods：The participant subjects were recruited from local advertisement. All subjects are students attending ordinary middle and high school. Their degree of achievement was average or below average. Before the study, its nature and purpose were fully explained to the patients and their parents, and a written informed consent was obtained from each child's parent and a written assent from each child for entire the procedure. The Ethics Committee and Clinical Research Committee of Gyeongsang National University Hospital approved the protocol. For baseline assessment, all subjects received tests for attention and memory. All tests were conducted by a certified psychologist. Stroop test, continuous performance test and trail making test A and B were used for evaluation of attention. As memory tests, we used memory assessment scale(MAS), standardized memory assessment tools. Ten to fourteen days after initial assessments, same tests was applied to the same subjects after prior 5 minute oxygen inhalation. Results：1) Attention test：Improved performances in trail making part B, and stroop test were found in normobaric oxygen inhalation group compared to air inhalation group. Improved reaction time in those tests seemed to reflect the enhanced executive prefrontal activity. 2) Memory test：More words and digits memorization were found in short-term memory subscale score in MAS in oxygen inhalation group compared to air inhalation group. This finding suggested the improved working memory function after oxygen inhalation. Conclusion：Though interpreted cautiously, these results suggested that normobaric oxygen inhalation could enhance executive function and working memory of prefrontal lobe. Further study, however, should be performed to investigate the mechanism of effects of oxygen on cognitive enhancement.

최근에 수행된 철골모멘트 접합부의 실험 및 해석결과에 의하면, 기둥으로 각형강관을 가진 접합부가 H형강을 기둥으로 사용하는 접합부에 실험체에 비해서 조기에 스캘럽 단부에서 취성파단이 발생하는 열등한 변형능력을 나타냈다. 이는 각형강관 기둥의 면외변형에 따른 보 웨브의 모멘트 전달효율의 저하, 스캘럽이 가지는 노치효과 및 합성보의 구속효과가 주요원인으로 밝혀졌다. 실험결과는 또한 개선된 수평스티프너로 하부 플랜지를 보강한 실험체는 우수한 변형능력을 가짐을 보였다. 본 연구에서는 이러한 영향을 고려하여, 다양한 수평스티프너로 보강된 접합부에 관한 유한요소해석을 실시하였다. 해석결과를 바탕으로 파일럿 테스트를 실시한 결과, 수평스티프너로 보강된 RBS 접합부 (SR)와 연장된 수평스티프너를 가진 접합부(LH)는 우수한 변형능력을 보였다.
