This single-blinded, nonequivalent control group pretest-posttest study was undertaken to evaluate the effectiveness of simulation education on clinical judgement, collaboration, communication skills, and perceived education practices and simulation design characteristics among student nurses in Korea. Participants were 47 students (19 in the experimental group and 28 in the control group) recruited by convenience sampling. The simulation based clinical reasoning education consisted of seven weekly, 120-minute high fidelity simulations. All participants completed the pretest and 7-week post measurements of a clinical judgment, collaboration, and communication skills with 4-week post measurement of collaboration, and participants in the experimental group provided a measurements of perceived education practices and simulation design characteristics. Data were analyzed using repeated measured ANOVA, and mixed linear model with SAS 9.2. Significant improvements were found in the experimental group for clinical judgment, collaboration, communication skill, and perceived education practices and simulation design characteristics. The study results show the impact of the perceived education practices and simulation design characteristics on facilitating the effectiveness of simulation education. The findings suggest a feasible and sound teaching method for student nurses and the need for further studies with a larger sample.

Objective : This study was designed to determine the effects of sensory integration group therapy with regard to the sensory processing, peer interactions, and task performance, and whether they continue. Methods : Twelve children aged 7 to 13 years enrolled in this study for 60 minutes per session, three times a week for 8 weeks. Sensory integration group therapy consisted of a total of 24 activities that included sensory processing, play skills, and interaction with peers. Short Sensory Profile was used to select subjects. In order to measure the outcome, we used the Short Sensory Profile, Penn Interactive Peer Play Scale and Canadian Occupational Performance Measure at pre, post, and follow-up evaluations. The results were analyzed by means of repeated measures analysis, and the pre-test, post-test, and follow-up tests were compared using the Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy, sensory processing, peer interaction, and task performance significantly improved(p<.05). In addition, we confirmed that the effects of treatment were maintained in the 4 weeks follow-up test. Conclusion : Sensory integration group therapy is an effective way of mediating effects not only by improving sensory processing skills, but also by providing imitation and training in groups for children in need of peer interaction and linking them to daily life.

Big Data technology has been attracted much attention in aspect of fast data processing. Research of practicing Big Data technology is also ongoing to process large-scale structured data much faster in Relatioinal Database(RDB). Although there are lots of studies about measuring analyzing performance, studies about structured data loading performance, prior step of analyzing, is very rare. Thus, in this study, structured data in RDB is tested the performance that loads distributed processing platform Hadoop using Apache sqoop. Also in order to analyze the influence factors of data loading, it is tested repeatedly with different options of data loading and compared with data loading performance among RDB based servers. Although data loading performance of Apache Sqoop in test environment was low, but in large-scale Hadoop cluster environment we can expect much better performance because of getting more hardware resources. It is expected to be based on study improving data loading performance and whole steps of performance analyzing structured data in Hadoop Platform.

This research is to find out which position is more effective on exercise. This study compared paricipants in their twenties on sitting position & standing position doing abdominal breathing of their respiration & abdominal muscle activation for 4 weeks. In sitting position, FEV1 was the biggest after breathing exercise. In standing position, the gap was biggest between the FEV1 & forced expiratory flow before and after the exercise. In standing and supine position, Lt. rectus abdominis before exercise and Rt. rectus abdominis after exercise muscle activities were the biggiest. Both posture exercise of repeated measure of analysis result, before and after the exercise of the rectus abdomonis muscle and external oblique muscle were not difference in both muscle activity(p>.05). Left Musculus obliquus externus abdominis before and after physical exercise, it's showed a meaningful difference(p<0.05). Before and after exercise, saw a meaningful difference the efforts of FEV1/FVC(p<0.05). The left external oblique abdominis muscle showed the most muscle activity in the supine position before/after exercising, the efforts expiratory showed the lowest muscle activity.The results from the repeated measures ANOVA regarding to before/after the volume and muscle activity, it showed significant difference between at the right rectus abdominis muscle(p<.05). This study finally gathered data about the muscle activity according to the position. This could be used to find in what position the abdominal breath exercise is the post effective & a new treatment for the patients who has worsened respiration function.

The purpose of this study was to determine whether changes of position might effect the convergence pulmonary function of the 20s men of mild intellectual disabilities with obesity. Ten subjects of mild intellectual disabilities with obesity(fat group) and ten contrary subjects without obesity(control group) were participated in the experiment. Subjects were assessed for their pulmonary function by using Fit mate according to the position changes(supine position, 45 lean sitting position, 90 sitting position). One-way repeated ANOVA analyzed each region data of pulmonary function of both the fat group and the control group according to their position changes. The result of the experiment showed that the 20s men of mild intellectual disabilities with obesity have lower pulmonary function than the contrary subjects in the each given posture. In comparison with three experimental positions, supine position was the lowest in the pulmonary function. This study showed the 20s men of mild intellectual disabilities with obesity have lower function of pulmonary volume than the control group, and thus, it suggests that the pulmonary functional data of 20s men of mild intellectual disabilities with obesity in this experiment can be used as a basic respiratory one for the various exercise programs in the area of the physical activities.

This study intends to evaluate the balance ability of Korean adults in their 20s and create balance indicators using digital equipment(FRA 510 S). The study participants participated in 50 men and women in their 20s without musculoskeletal and nervous system diseases. For data analysis, Repeated Measures ANOVA was used. As a result of the study, it was confirmed that the movement of the body weight was higher when the eyes were closed and the test was performed than when the eyes were opened on a flat floor and a balance pad(47cm×39cm×5.5cm). And there was no difference according to the gender of men and women. In a future study, it is considered that the balance ability of normal elderly people will be evaluated, and the balance index of normal adults in Korea will be created and applied to the evaluation of patients with impaired balance ability.

The purpose of this study is to examine the effects of spiritual education for spiritual care competence reinforcement of nursing students. 83 subjects of nursing students were participated in two universities located in J city(from February 27 to May 19, 2017) and composed of 42 in the experimental group and 41 in the control group. The spiritual education was composed of three sections; self-awareness, spirituality, and spiritual dimension in nursing. This program was then implemented on the subjects for a total of 10 sessions with each session lasting 120 minutes and given 2 times a week for 5 weeks. The data collected were analyzed for descriptive statistics, χ2-test, Independent t-test and Repeated ANOVA. This spiritual education increased the spirituality, ego-identity, spiritual well-being, satisfaction with life, and spiritual care competence of the nursing students. The effectiveness of the spiritual education also maintained in five weeks after intervention. It is therefore proposed that this education be utilized for the nursing students as basic standardization process of a spiritual nursing care.

With the ease availability of statistical software and powerful computers the application of statistical methods in domestic veterinary journals is on the increase. In parallel with this benefit, statistical errors are not uncommon even in renowned scientific and medical journals. These errors may lead to misinterpretation of the data, thereby, subjected to faulty conclusions. A systematic review of articles published in 8 issues of the Journal of Veterinary Clinics during 2006-2007 was performed to assess the statistical methodology and reporting. Ninety-four (72.9%) articles of the 129 original articles screened included any inferential statistical analysis in the article, including comparison of 3 or more groups (53 or 56.4%), comparison of independent 2 groups (40 or 42.6%), and paired t-test (9 or 9.6%) in order. Of the 94 articles in which statistical analysis was done 62 (or 66.0%) had at least 1 statistical error. Errors included failure to apply or incorrectly applying independent Student's t-test for paired data or vice versa, inappropriate use of t-test for more than 3 groups and failure in chi-square test to consider continuity-correction for small expected frequencies. The common errors in ANOVA were failure to validate assumption of the test, inappropriate post-hoc multiple-comparison and incorrect assumption of independence of data in repeated measures design. Reporting errors included failure to state statistical methods and failure to state specific test if more than 1 test was done. It is suggested that an editorial effort would be necessary to achieve the improvement of appropriate statistical procedures through the publication of statistical guidelines to author(s).

The purpose of this study was to compare the shoulder stabilizer muscle activity during a push up plus on a different conditioning surface. Eighteen healthy volunteers were tested. Surface EMG was recorded from the upper trapezius(UT), pectoralis major(PM), and serratus anterior(SA) using surface differential conditions. Measurements were performed for 7 days. The mean root mean square (RMS) of EMG activity was calculated. A one-way repeated measures analysis of variance was performed to compare RMS normalized values. The UT and PM did not show significant differences of electric activation amplitude in relation to different surface conditions(p>.05). However, the SA showed greater mean electric activation amplitude values on the push up plus exercise on a upper and lower unstable surface(p<.05). These results suggest that to improve SA EMG activity is more useful when performed on a upper and lower unstable surface conditions than on a stable surface conditions.
