  • Purpose: The purpose of this study was to evaluate the effect of a self-evaluation method using video recording on competency in nursing skills, self-directed learning ability, and academic self-efficacy in nursing students. Methods: The study design was a non-equivalent pre-post quasi-experimental design. The experimental and control groups were randomly assigned with 35 participants in each group. Interventions for the experimental group were video recording and students' self-evaluation of what they did. Nursing skills included in the study were tube feeding, intradermal injection, subcutaneous injection, and intramuscular injection. Competency in nursing skills was measured one time at the end of the study using a checklist. Self-directed learning ability and academic self-efficacy were measured 3 times (pre-, mid-, and post-intervention) over the 8 weeks. Independent t-test, chi-square test, and repeated measures ANOVA were used for data analyses. Results: There was no statistically significant difference for competency in nursing skills and self-directed learning ability over the 8 weeks of the practice session. There was a significant difference in academic self-efficacy by groups over time. Conclusion: Results indicate that self-evaluation method using video recording is an effective learning way to improve academic achievement in nursing students.

  • Purpose: This study investigates the effects of task-oriented training for a left trunk flexion pattern using real-time ultrasound imaging in a stroke patient with unilateral neglect symptoms. Methods: This study used the ABA experimental design, which is a single-subject research method among individual case research methods. For the ABA experimental design, changes in the degree of unilateral neglect, balance ability, and the thickness of the lateral abdominal muscle were visually analyzed during the baseline process, in the intervention period, and after the intervention. The experiments were performed 24 times in total for 8 times in each of the 3 periods. The unilateral neglect was measured using the Albert test, balance ability was measured using the Berg balance test, and the thickness of the lateral abdominal muscle was measured using ultrasound imaging. The subject was a 50-year-old male patient with unilateral neglect caused by right cerebral hemorrhage. He performed task-oriented training for a voluntary left trunk flexion pattern using real-time ultrasound imaging during the intervention period. Results: The result of comparing the data collected during the intervention period with the data point average of the baseline process showed that balance ability improved and the tendency line was above the baseline. The tendency line of unilateral neglect was below the baseline and showed a decreasing tendency. The thickness of the lateral abdominal muscle showed an increasing trend and the tendency line was above the baseline. Conclusion: The results of this study suggest that the task-oriented training for left trunk flexion pattern using real-time ultrasound imaging has a beneficial effect on balance ability, the degree of unilateral neglect, and the strength of the lateral abdominal muscle in unilateral neglect patients.

  • Concrete structures need repairing due to various reasons such as deteriorative effects, overloading, poor quality of workmanship and design failures. Cement based repair mortars are the most widely used solutions for concrete repair applications. Various factors may affect the bond strength between concrete substrate and repair mortars. In this paper, the effects of polymer additives, strength of the concrete substrate, surface roughness, surface wetness and aging on the bond between concrete substrate and repair mortar has been investigated. Full factorial experimental design is employed to investigate the main and interaction effects of these factors on the bond strength. Analysis of variance (ANOVA) under design of experiments (DOE) in Minitab 14 Statistical Software is used for the analysis. Results showed that the interaction bond strength is higher when the application surface is wet and strength of the concrete substrate is comparatively high. According to the results obtained from the analysis, the most effective repair mortar additive in terms of bonding efficiency was styrene butadiene rubber (SBR) within the investigated polymers and test conditions. This bonding ability improvement can be attributed to the self-flowing ability, high flexural strength and comparatively low air content of SBR modified repair mortars. On the other hand, styrene acrylate rubber (SAR) modified mortars was found incompatible with the concrete substrate.

  • The purpose of this study was to examine the effects of analytic rubrics on learners' self-directed learning ability in information technology unit assessment. The experiment and control groups were 4 classes of the 2nd grade in B middle school located in Daejeon. The pretest was performed to check the group homogeneity. For the experiment design, the nonequivalent control group design as a type of quasi-experimental design was used. The experiment was composed of 5 sessions. Statistical significance was p < .05 to verify the hypothesis, and SPSS 12.0 for Windows was used for statistical treatment. The results from this study were as follows: (1) The application of analytic rubrics in information technology unit assessment affected learners' self-directed learning ability in a positive way in 4 factor's(openness, self-concept, intrinsic motivation, self-evaluation) but does not affected in 3 factor's(autonomy, creativity, problem solving). (2) The difference in sex was not a statistically significant factor in the application of analytic rubrics in information technology unit assessment. Based on the results of the experiment, two suggestions were made to promote the application of rubrics in technology education assessment. (1) Research and development of many types of rubrics for technology education are needed. (2) Systematic training of rubrics for technology teachers is needed.

  • Objectives: The purpose of this study was to evaluate the effects of assertiveness training on assertiveness behavior, problem solving ability, and interpersonal relationships of nursing college students. Methods: A nonequivalent pre- and post-test experimental design was used. This study included 15 subjects in the experimental group, and 15 subjects in the control group, who were sophomore nursing students recruited from Gachon Nursing School located in Inchon City. The experimental group received 8 series of a ready planned and reorganized assertiveness training course, while the control group did not receive any training. The 120 minute training session was held on a weekly basis. The Maan-Whitney U Test was done to identify the changes in scores of assertiveness behavior, problem solving ability, and interpersonal relationships between the experimental and the control groups, after the assertiveness training. The data were collected before and after each part of the assertiveness training. The data collection period was from May 7 to July 10, 2001. Results: 1) The assertiveness behavior scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. 2) The self problem solving evaluation scores of the nursing students who received assertiveness training were higher than those of the nursing students who did not receive the training. 3) The interpersonal relationship scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. Conclusion: The study results showed that the assertiveness training was effective in promoting assertiveness behavior, problem solving ability, and changes in interpersonal relationships in nursing college students. It is suggested that well designed strategies are needed in the further studies in order to expand and apply the assertiveness training to other nursing student and nurse cohorts.

  • Objective: Kinesio tape has been applied to the ankle to improve balance and gait. Stroke patients show abnormal gait patterns due to foot drop. This study aimed to determine the effects of ankle balance taping which to support the ankle joint on balance and gait in patients with chronic stroke. Design: A randomized controlled trial. Methods: Twenty-four chronic stroke patients were selected and randomized into experimental group (n=12) and control group (n=12). The experimental group applied kinesio taping three times a week for three weeks, and the control group applied placebo taping for the same amount of time. To evaluate the effectiveness of the treatment, the subjects' walking ability, static balance, and dynamic balance were assessed before and after the experiment. Gait speed and spatiotemporal gait ability were measured to examine walking ability, postural sway velocity and velocity moment for static balance, and Timed-Up and Go test and Berg Balance Scale were conducted to check dynamic balance. Results: The experimental group showed a significant increase in walking ability, static balance, and dynamic balance in the within-group pre-post difference (p<0.05). In the between-group comparison, the experimental group had a significant difference in walking ability than the control group (p<0.05). Conclusions: Ankle balance taping can help improve gait, and this study can be used as a basis for future studies of ankle balance taping.
