  • The purpose of this study is to evaluate the effect of horse-riding simulator exercise on the static balance of chronic stroke patients. The study's sample included 30 stroke patients who were randomly classified into an experiment group and a control group. Both the experiment and control groups received therapeutic exercise one time per day, but the experiment group also received twenty minutes of horse-riding simulator exercise three times per week for six weeks. To compare the groups, an independent t-test was performed, and to compare each period, a paired t-test was conducted and its result was analyzed. The result of this study, moving distance under standing position with eyes closed, showed significant difference in horse-riding simulator exercise group after exercise. But, there was no significant difference between horse-riding simulator exercise group and control group. Further, various clinical studies focusing on effects of horseback riding exercise on function of stroke patients are needed.

  • This study was aimed to identify surgical ward nurses' importance-performance awareness toward early mobilization after abdominal surgery patients. The date were collected from 162 nurses and the importance and performance of early mobilization were analyzed by the IPA method. The collected data were analyzed using the SPSS/WIN 25.0 by implementing descriptive statistics, independent t-test, paired t-test, and ANOVA. Early mobilization was divided into exercise of pulmonary complications and early ambulation. As a result of the study, the areas requiring concentration were 'check risk of aspiration', and areas requiring improvement were 'oral care', 'check lung sound', 'percussion/vibration', 'suction', and 'reinforcement exercise in bed'. Therefore, each item of early mobilization is recommended to reduce the gap between importance and performance in clinical care.

  • The purpose of this study was to investigate the related variables of the resilience of Korean young adults. The sample was 464 young adults aged 19-34 years who had never been married, both parents alive and living with one or more of their parents in the Seoul metropolitan region. The collected data were analyzed by descriptive statistics, factor analysis, t-test, paired t-test, one-way ANOVA, and multiple regression analysis using SPSS ver.23 and AMOS 23.0. The resilience of young adults was significantly related to the variables of gender, maternal helicopter parenting, bonding social capital, and bridging social capital. As a result, this study showed that the resilience of young adults was formed and promoted by the combined effects of the family-related environment and social-related environment. The results of this study provide meaningful data that should be considered in the counseling and education field when developing programs to build the resilience of young adults. Policy implications for improving the resilience of Korean young adults are discussed.

  • In the previous article in this series we introduced the basic concepts for statistical analysis. The present review introduces hypothesis testing for continuous and categorical data for readers of the veterinary science literature. For the analysis of continuous data, we explained t-test to compare a single mean with a hypothesized value and the difference between two means from two independent samples or between two means arising from paired samples. When the data are categorical variables, the $x^2$ test for association and homogeneity, Fisher's exact test and Yates' continuity correction for small samples, and test for trend, in which at least one of the variables is ordinal is described, together with the worked examples. McNemar test for correlated proportions is also discussed. The topics covered may provide a basic understanding of different approaches for analyzing clinical data.
