Purpose: The purpose of this study is to use P300 latency to determine whether methods of motor learning in terms of massed and distributed practice can affect motor sequential learning in healthy adults. Methods: Twenty-four healthy subjects participated in this study. They were randomly allocated into three groups: a 10 minute, a 12 hour, and a 24 hour group. In the SRT task, eight numbers were adopted as auditory stimuli. During an experiment, participants were instructed to press the matching key as quickly and accurately as possible when one of the eight numbers was presented randomly. The subjects practiced for three sessions, each of which comprised five blocks of 40 serial reaction time tasks. While they practiced during these three sessions, P300 latency was measured. The data were analyzed using ANCOVA. Results: The P300 latency of Fz, Cz, and Pz decreased in all groups except for the Fz area of the 10 min group. Overall, the P300 latency of the 10 min group showed a smaller decrease compared with the 12 hr and 24 hr groups. Statistically, no significant differences in the Fz and Cz areas were observed among the three groups. The P300 latency in the Pz area of the 10 min group showed a significantly smaller decrease compared with the other groups. Conclusion: These findings suggest that short-term sequential motor training can alter brain functions such as the P300 latency. We also found that better acquisition of a motor skill was obtained with distributed practice of a task than with massed practice.

This study was conducted to investigate how child-care teachers participate, practice mealtime instruction, and perceive difficulties in food service, focusing on comparison between the teachers caring two different age groups: children younger than three years (Younger Group) and those three years or older (Older Group). Questionnaires were distributed to 151 child-care centers in Kwanak-gu, Seoul, Korea during December, 2011. Only the data from 25 child-care centers, where two respective teachers in charge of Younger Group and Older Group completed the questionnaires, were analyzed. The results showed that there was no difference in terms of child-care teachers' participation in food service practice between the two groups, except for serving method; 'Pre-plated' serving was used significantly more often in Younger Group, whereas 'Line-up' serving was used in Older Group. Approximately, three quarters of the child-care centers had policies or guidelines on mealtime instruction. During mealtime, child-care teachers tended to use frequently verbal instructions such as "sit up straight when you eat" about eating manner, "don't be picky with your food" about eating habit, and "wash your hands before eating" about eating procedure in both the groups. There was no statistically significant difference regarding child-care teachers' perceived difficulties in food service between the two groups. These results indicated that child-care teachers' participation and mealtime instruction in food service did not differ between the two age groups, although children's development of digestion and eating skill differed by age. Therefore, training should be provided to child-care teachers about food service practices and mealtime instruction appropriate to children's age.

Purpose: This study was carried out to describe the process and evaluation of a critical thinking class for new community health practitioners. Methods: The case study design was used to develop and evaluate a critical thinking class for 46 participants in the community health practitioners training program. The class was held two hours a week for 8 weeks. Critical thinking disposition was tested before and after the class and critical skill was graded according to the final test score. Data analysis was performed using descriptive statistics and paired t-tests using SPSS WIN 20.0. Results: Clinical critical thinking competences were identified through the literature review. The case situations with questions guiding the problem-solving process were developed and used for group discussion. Critical thinking disposition of participants was determined to have increased slightly after having taken the class. 17.4% of the participants had a competency level high enough to solve a problem and half of them stayed at the level of understanding of critical thinking. Compared with the class's satisfaction with the relevance to their jobs, the satisfaction with the learning method and instructor was high. Conclusion: The findings of this research will serve as the basis for developing critical thinking classes for community health nurses in order to improve their critical thinking competence.

Purpose: This study was conducted to examine the effects of simulation-based practice using standardized patients for the care of woman with postpartum hemorrhage as related to clinical performance competence and critical thinking deposition of nursing students. Methods: A nonequivalent control group pre-post test experimental design was used. Fifty four third year students were recruited, 29 students for the experimental group and 25 students for the control group. The simulation-based practice about nursing care related to postpartum hemorrhage included skill training, team-based practice, and debriefing. It was implemented with the experimental group for about 30 minutes in October 6, 2011. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability, and t-test using the SPSS/WIN program. Results: The experimental group who had the simulation-based practice showed significantly higher knowledge and skills of clinical performance competence than the control group (t=2.19, p=.003). But the experimental group who had the simulation-based practice did not show significantly higher critical thinking deposition than the control group (t=-0.32, p=.748). Conclusion: The results indicate that a simulation-based practice is an effective teaching method to improve knowledge and skills for clinical performance competence of nursing students. Further study is needed to identify the effect of a simulation-based practice on nursing attitudes.

The purpose of this study was to investigate factors associated with the critical thinking ability of nursing students at the individual and school levels. The study adopted a descriptive design and recruited 465 nursing students from four nursing schools from November 2014 to September 2015 through convenience sampling. The Clinical Critical Thinking Skill Test was used to measure critical thinking ability, and the data were analyzed with the SAS ver. 9.4 program (SAS Institute Inc., Cary, NC, USA) for descriptive statistics, t-test, analysis of variance, and multi-level model. The results showed that clinical practicum experience (${\beta}=-0.72$, p=0.025), taking critical thinking courses (${\beta}=0.63$, p=0.010), and taking simulation courses (${\beta}=0.56$, p=0.035) improved critical thinking ability in the individual level model. In the school level model, the interaction effect between the years of clinical practice done by the student and the presence of full-time clinical instructors was significant (${\beta}=1.29$, p=0.011). These results suggest that critical thinking ability improves with the more years of clinical practice individual nursing students have, and this improvement is greater with the presence of full-time clinical instructors in the school. Therefore, it is recommended that nursing students undergo critical thinking and simulation courses to develop their critical thinking ability, and dedicated clinical instructors in nursing schools should play a vital role.
