  • PURPOSE: This study examined the effects of both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation on the balance and gait of stroke patients. METHODS: Ten patients with stroke were divided randomly into two groups of five patients each who met the selection criteria. The training was conducted five times a week, for 60 minutes. The experimental group received both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation while the control group received general physical therapy with functional electrical stimulation. RESULTS: The timed Up-and-Go (TUG) test result was statistically significant after the intervention in the experimental group (p<.041). Berg Balance Scale (BBS) assessment was statistically significant after the intervention in the experimental group (p<.047) and between the experimental and control groups (p<.012). The cadence assessment was statistically significant after intervention in the experimental group (p<.031) and between the experimental and control groups (p<.015). The stride length assessment was not statistically significant after intervention in the experimental group and between the experimental and control groups. Gait velocity assessment was statistically significant after the intervention in the experimental group (p<.031) and between the experimental and control groups (p<.015). CONCLUSION: Both lower extremities proprioceptive neuromuscular facilitation training with functional electrical stimulation had positive effects on the balance and gait of stroke patients.

  • 과학교육에서 컴퓨터는 교수 학습 뿐 아니라 평가의 목적으로도 활용되고 있다. 죽, 컴퓨터의 장점을 살린 컴퓨터 기반 평가가 실시되고 있다. 그러나 이와 같은 평가는 주로 과정 중심이 아닌 결과 중심의 평가이며, 피험자의 수만큼 컴퓨터가 있어야 하므로 학교의 정규 시험으로 활용하기 곤란하다. 그러나 수행평가의 경우 일반적으로 평가 과제가 미리 공개되므로 학급별 또는 학생별로 평가 시간이 다르게 평가를 실시하는 것이 가능하다. 따라서 본 연구에서는 실제 실험기구를 사용한 실험평가를 대체할 수 있는 컴퓨터 기반 수행평가 문항을 개발하였다. 이를 위해 먼저 물리 교사를 대상으로 과학교육에 있어 이러한 기능에 대한 평가의 필요성 및 어려운 점 등에 대한 설문조사를 실시하였고, 이를 반영하여 전류계와 전압계를 포함한 회로를 구성을 하는 평가 문항을 개발하였다. 개발된 컴퓨터 기반 문항은 실제의 실험기구를 사용하여 진행되는 평가와 유사하게 구성하였으며 평가 과정에서 학생들의 수행에 따라 적절한 피드백을 제공하고, 수행 결과를 자동적으로 채점할 수 있도록 하였다. 이를 위해 컴퓨터가 학생들의 수행 결과의 정확성을 판단할 수 있는 알고리즘을 개발하였다.

  • Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using $x^2$-test (Fisher's exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.

  • As the application of quantitative risk assessment (QRA) to food safety becomes widespread, it is now being questioned whether experimental results and simulated results coincide. Therefore, this paper comparatively analyzed experimental data and simulated data of the cross contamination, which needs summation of the simplest calculations in QRA, of chicken by Monte Carlo simulation and fuzzy math computation. In order to verify summation, the following basic operation was performed. For the experiment, thigh, breast, and a mixture of both parts were preserved for 24 hr at $20^{\circ}C$, and then the cell number of Salmonella spp. was measured. In order to examine the differences between experimental results and simulated results, we applied the descriptive statistics. The result was that mean value by fuzzy math computation was more similar to the experimental than that by Monte Carlo simulation, whereas other statistical descriptors by Monte Carlo simulation were more similar.
