This study aimed to investigate the effects of learning with role-playing on student satisfaction and achievement regarding behavior management teaching in pediatric dentistry. 93 students were divided into 19 groups and randomly assigned to role-play as a doctor, patient, parent, assistant, or narrator. Their performances were evaluated by the instructor and the satisfaction survey was conducted. All participants took the written test and were asked to compare lecture and role-playing with regard to the effectiveness of learning. Statistical analysis was performed with Mann-Whitney U test, Independent T-test, and Kruskal-Wallis test. 68 students (73.1%) who believed that the role-playing was more helpful than lecture showed higher level of satisfaction than students who believed lecture was more helpful. But there were no differences in the tutor evaluation score and the written test scores. Participants in the patient management scenario showed higher level of descriptive question scores of the written test and tutor evaluation score than those who participate in the parent management scenario. There were no differences between the role groups. Role-playing may help students to become more interested and participatory in learning behavior management. The level of satisfaction may differ by the design and content of the scenario.

This study was undertaken to examine changes in the performance of nurses before and after initial cardiac arrest, and compare the performance, confidence, and satisfaction between two groups: group 1, Rapid Cycle Deliberate Practice simulation method; group 2, traditional simulation method. The participants were 122 nurses (group 1: 62, group 2: 60). Data were collected from March 18 to 29, 2019 and analyzed using the SPSS Version 23.0 program, by applying descriptive statistics, Fisher's exact test, t-test, Wilcoxon sign rank test, and Mann-Whitney U-test. Comparing the educational effects of the traditional simulation training vs. RCDP simulation training, some items of performance were significantly different (z=-2.02, p=0.044 / z=-2.42, p=0.015 / z=-3.03, p=0.002), but no difference was observed in the levels of confidence (z=0.388, p=0.699) and satisfaction (t=0.72, p=0.476) between the two groups. This study confirms that both training methods are effective teaching modules for enhancing the nurse's ability to perform resuscitation with confidence. Hence, we suggest applying the appropriate simulation method, according to the subjects included during education, and contents in the training of Advanced Life Support for nurses. Effectiveness of the modules can be ascertained by applying the RCDP simulation training method in various fields.

This study aims to identify the effects of experiencing health promotion education on the present health status of elderly people. The subjects of this study were a total 10,532 elderly people (aged 65 years or older), and who were selected from the data of the '2017 Community Health Survey'. The health promotion education experience consisted of handwashing education/campaign, a non-smoking campaign and non-smoking education. The chronic disease control education experience consisted of education on hypertension, diabetes mellitus and arthritis. Psychiatric counseling consisted of consultations on stress, depression and suicide. The present health status consisted of the patients' ability to exercise, their self-care ability, their activities of daily living, their pain/discomfort and their anxiety/depression. The data was analyzed utilizing the chi-square test, the Mann-Whitney test and multivariate logistic regression analysis. The general characteristics of the subjects were 4,075 males (38.69%) and 6,457 females (61.31%). The average age was 73.71(±6.18) years old. The significant factors influencing the elderly peoples' present health status were age (OR=0.909, 95% CI=0.886-0.933), handwashing education/campaign (OR=2.463, 95% CI=1.703-3.563), a stop smoking campaign (OR=1.624, 95% CI=1.146-2.301) and consultation for mental problems (OR=0.533, 95% CI=0.359-0.791). In conclusion, to modify the personal habits that the elderly have had for a long time and to show the effects of education, long-term continuous education that focuses on the characteristics of the people will be effective.

Traffic accidents on highways are likely to happen when there is an imbalance in the complex relationships among key elements such as road geometries, driver related factors, and mechanical performances. The Demand-Effort Model (DEM), which evaluates highway safety, can be explained by the imbalance, which occurs when the level of demand of the driver's attention to the road environment exceeds that of the response from the driver. This study suggests a new model that improves the reliability of the current DEM through the reinterpretation on the physiological signals with the help of the Neural Network Model (NNM). The data were collected from 149 subjects, who drove a test vehicle on the Yongdong, Honam, and Seohaean Expressways in Korea. Three important results could be drawn from the recursive tests as follows; (1) Only 5 out of 10 parameters on the physiological signals which are currently used were proven to be meaningful through the Normality Test, Cluster Analysis, and Mann-Whitney Analysis. (2) The revised DEM, which internally uses the NNM, showed more reliable results than existing DEM. Group 1, which is based on the new DEM showed 80.0% of accuracy in measuring the level of driver's efforts, however, that of Group 2 based on the current DEM was 74.3%. (3) Field tests on the Honam Expressway showed lower 'type II error' with the new DEM (40.5%) than the old DEM (58.8%). The DEM is designed as a quick and easy way to determine highway safety prior to the minute road safety audit (RSA) by a professional audit team. Then a new DEM, which is based on the NNM, needs to be considered since it showed higher reliability and lower error.

This study was conducted to investigate the relationship between hand grip strength and cardiopulmonary fitness in patients with myocardial infarction. In this retrospective study, 67 patients who experienced myocardial infarction for 10 months were analyzed. Hand grip strength was measured using a handheld dynamometer. Dynapenia was diagnosed based on a dominant hand grip strength of less than 30 kg for males and 20 kg for females. A cardiopulmonary exercise test was performed using a treadmill. Physical activity status was also evaluated. Cardiorespiratory fitness parameters were analyzed using a t-test and a Mann-Whitney test. VO2max, METmax, and exercise time significantly decreased in the dynapenia group compared with the non-dynapenia group. Correlation analysis revealed that dominant handgrip strength was significantly related to cardiorespiratory fitness parameters. Moreover, VO2max, METmax, and exercise time were significantly increased in patients with vigorous activity compared with the sedentary group. These findings indicate that handgrip strength could potentially be used as a marker of cardiorespiratory functions. Accordingly, patients with myocardial infarction should be evaluated for grip strength and physical activity, and we can encourage patients to participate actively in cardiac rehabilitation.
