Purpose: The purpose of this study was to compare practice stress and practice satisfaction between clinical practice and simulation-based practice groups. Methods: A total of 159 nursing students (85 in the simulation group and 74 in the NICU group) participated in the study. Research tools measuring practice stress and practice satisfaction were used. Data was analyzed utilizing a t-test, Mann Whitney U-test, and descriptive statistics. Results: The simulation group showed a lower level of practice stress(practice instruction, practice evaluation, interpersonal relationship) a higher level of practice satisfaction compared with the NICU group. Conclusion: Simulation-based practice is an effective learning method for high-risk newborn nursing and can be used as an alternative to clinical practice.

Purpose: This study was performed to identify in nursing students the effects of simulation practice for hemorrhagic patients. Methods: Subjects were sophomore nursing students in Daegu (n=133). A self describing performance questionnaire which included knowledge, skill and attitude towards bleeding patients was given. Consent was received from students. The data was analyzed by ANOVA with Scheffe's test and Mann-Whitney U test using the SPSS 12.0 Program. Result: Subjective and objective knowledge and skill showed significant improvement in the control group, especially in assessment, correct medication administration, explaination of NPO and preparing the crash cart for a cardiac arrest. Objective knowledge and skill was significantly higher in the control group although attitude was not. Conclusion: Simulation practice was an effective education method for improving knowledge, skill and attitude in nursing students.

Objectives : This study is a quasi-experiment with a pre-post design and a nonequivalent control group performed from May 1 to June 2, 2013 to verify the effects of a simulation based education program on nursing students' self-confidence, and clinical performance ability. Methods : The subjects of the study were a total of 60 students in their fourth year of a nursing program at a university located in G city and they were assigned to an experimental group of 30 students and a control group of 30 students by convenience sampling. Results : After being offered education, self-confidence, and clinical performance ability were significantly more improved than before in each group. In the comparison of the two groups, the self-confidence (t=3.00, p=.004) and clinical performance ability(t=3.14, p=.003) of the experiment group were significantly higher than those of the control group. Conclusions : The results indicated that instructional methods using a simulation-based emergency care program should be adopted maximize the effects of advanced cardiopulmonary life support education.

Substructure pseudo-dynamic hybrid simulation (SPDHS) combining the advantages of physical experiments and numerical simulation has become an important testing method for evaluating the dynamic responses of structures. Various parameter identification methods have been proposed for online model updating. However, if there is large model gap between the assumed numerical models and the real models, the parameter identification methods will cause large prediction errors. This study presents an ANN (artificial neural network) method based on forgetting factor. During the SPDHS of model updating, a dynamic sample window is formed in each loading step with forgetting factor to keep balance between the new samples and historical ones. The effectiveness and anti-noise ability of this method are evaluated by numerical analysis of a six-story frame structure with BRBs (Buckling Restrained Brace). One BRB is simulated in OpenFresco as the experimental substructure, while the rest is modeled in MATLAB. The results show that ANN is able to present more hysteresis behaviors that do not exist in the initial assumed numerical models. It is demonstrated that the proposed method has good adaptability and prediction accuracy of restoring force even under different loading histories.

교사를 양성하는 사범대학이나 교육대학에서는 해마다 학교현장에 많은 교사들을 배출하고 있다. 예비 교사들은 매력적인 수업의 설계와 시행, 수업기술을 향상 시킬 수 있는 기술을 충분히 습득해야 한다. 학교는 시행착오의 장이 아니며, 교사는 시행착오를 최소화하여 학생들을 지도해야할 중책을 맡고 있기 때문이다. 예비교사나 초임교사들이 효과적인 학습목표 달성을 위한 수업기술을 시뮬레이션을 통해서 훈련 한다면 학교 수업환경 개선은 물론, 교사의 역량 또한 강화될 수 있을 것이다. 본 연구는 문헌고찰을 통하여 예비 및 초임교사의 발문기술 증진을 위한 시뮬레이션 도입을 위한 시뮬레이션의 개발을 위한 당위성과 개발을 설계 방향을 제시하는데 있다.

Purpose: The purpose of this study is to identify the educational effect among nursing students who performed the patient role in women's health nursing simulations. Methods: In this exploratory qualitative study, a sample of 31 third- and fourth-grade nursing students who participated in scenario-based patient roles in clinical performance examination of the women's health nursing simulation practice training. Data were collected through focus group interviews. Qualitative data were analyzed using qualitative content analysis. Results: Three themes emerged from the data analysis. Participants experienced an enhancement of patient-centered nursing competence, deep learning immersion and display of self-regulated learning. The difficulty of performing the patient role contributed additional effects such as the difficulty to perform the patient role in the psychological training environment. Conclusion: It is recommended to utilize nursing students as patients in simulation practice training. On the other hand, the psychological training environment can cause difficulties in performing patient roles, a burden on the role of the patient, and involves the interruption of the role.

Atomic force microscopy (AFM) simulation for Si (001) surface defects was conducted by using density functional theory (DFT). Three major defects on the Si (001) surface are difficult to analyze due to external noises that are always present in the images obtained by AFM. Noise-free surface defects obtained by simulation can help identify the real surface defects on AFM images. The surface defects were first optimized by using a DFT code. The AFM tip was designed by using five carbon atoms and positioned on the surface to calculate the system's energy. Forces between tip and surface were calculated from the energy data and converted into an AFM image. The simulated AFM images are noise-free and, therefore, can help evaluate the real surface defects present on the measured AFM images.

이 연구의 목적은 계절의 변화 원인을 설명하는 과정에서 초등학생들의 개념 시뮬레이션을 분석함으로써 학생들이 어떻게 계절의 변화 원인에 대한 설명을 어떻게 생성하고 있는지를 알아보고, 계절의 변화와 관련된 교육에 시사점을 주는 데 있다. 이를 위해 문헌 연구를 기반으로 개념 시뮬레이션 과정 및 전략 분석틀을 개발하였으며, 과학교육 전문가 4인의 내용타당도를 확인 받았다. 연구의 결과는 다음과 같다. 첫째, 계절의 변화 원인 설명 과정에서 초등학생들은 주로 과학수업에서 모형 실험을 통해 학습한 지각적 경험을 이용하여 설명을 만들고 있었으며, 친숙한 대상을 이용하여 사고실험 사례를 고안하거나, 친숙한 지각적 경험을 유추하여 설명을 확고히 하는 것을 돕고 있었다. 둘째, 개념 시뮬레이션 사례의 실수는 초기표상의 진술, 심상 시뮬레이션의 실행 과정에서 나타났으며, 참여자들의 초기표상 진술이 불완전하거나, 심상 시뮬레이션 실행에서 부적절한 상황을 떠올린 경우였다. 셋째, 초등학생들의 개념 시뮬레이션 과정에서 남중고도의 개념과 관련된 정신모델을 확고히 하기 위해 제거, 대체의 시뮬레이션 전략을 사용하는 것을 확인하였다.
