  • This study was a descriptive study conducted to identify factors that had an influence on clinical competency of core basic nursing skills(CBNS) during the clinical practice in nursing students. Data were collected from 3rd and 4th grade 190 nursing students in G city using self-report questionnaire, and analyzed using descriptive statistics, the t-test, one way ANOVA, multiple regression with SPSS 23.0 program. This study found that the number of experience CBNS below 5 was 51.1%, and the number of observation CBNS over 11 was 78.4%. Clinical competency according to general characteristics, clinical practice satisfaction and the level of CBNS experience increased with male, increase age and grade, and major subject satisfaction and clinical practice satisfaction, especially, as the number of experience CBNS increased, clinical competency increased(p<0.001). But clinical competency did not differ according to the number of observation CBNS(p=0.463). The factors affecting the clinical competency of nursing students were age, grade, clinical practice satisfaction and the number of experience CBNS. Therefore, it is important to increase the opportunity to directly experience the various CBNS in clinical practice of nursing students in the nursing education curriculum, and it is necessary to find ways to actively use simulation education.

  • The purpose of this study was to investigate the effect of applying whole body vibration exercise at 30 Hz on the thickness and mechanical properties of the erector spinae. The study population included 24 adults (11 male and 13 female) in the N region. The subjects were divided into two groups, a 30Hz whole body vibration exercise(WG, n=12) and an LSG(12 subjects). Changes in the thickness and mechanical properties of the erector spinae were analyzed before the exercises and after four and eight weeks of exercises using a two-way repeated analysis of variance with a statistical significance level of α=0.05. When there was an interaction between the groups and measurement times, post hoc analyses were conducted at a statistical significance level of α=0.01. The thickness, frequency, stiffness and strain of the erector spinae muscles were significantly different in each time period and in the interaction between time period and the group (P<0.05), and recovery was significantly different only in each time period (P<0.05). Thus, 30Hz whole body vibration exercise had a positive effect on the thickness and mechanical properties of the erector spinae. The results of this preliminary study suggest that whole body vibration exercise may find a place as a lumbar stabilization exercise in clinical practice in the future.

  • The purpose of this study is to investigate differences in learning flow and teaching presence according to the lecturer's appearance and the lecturer's speech rate. For this experiment, 183 freshman students from Xingtai University in China were selected as subjects of the experiment, and a total of four types of lecture videos were developed to test the lecturer's appearance and their speech rates. Data was analyzed through multivariate analysis of variance. According to the results of the analysis, first, learning flow and teaching presence of groups who experienced the presence of the lecturer appeared were significantly higher than the groups who learned without the appearance of the lecturer. Second, the groups who learned from videos with a fast speech rate showed higher learning flow and teaching presence than the group who learned at a slow speech rate. Third, there were no significant differences in both learning flow and teaching presence according to the lecturer's appearance and speech rate. This result provides a theoretical and practical basis for developing customized videos according to learners' characteristics.

  • As part of studies on the reduction of forest trails degradation caused by high users density, this study was carried out to investigate soil physical properties of forest trails of Gyeongnam Domain in Mt. Jiri, Southeast Korea. Since the forest were opened for leisure trailing in 2008, the average soil erosion amounts per a square meter on the forest trails were $0.0015m^3$ from Inweol to Gumgeo, $0.0018m^3$ from Dongang to Suchol, and $0.0027m^3$ from Suchol to Chungam for 3 years. But, from Chungam to Agyang, the erosion was almost not occurred because it was recently opened. The soil hardness in 5 cm depth was significantly higher than in 10 cm depth. It indicates that intensive soil compaction by users has mainly affected in 5 cm soil depth until now on. In three forest trails compacted intensively, the porosity of 0-7.5 cm soil layer was down to 1.4-1.5 times compared to that in 2008. In additions, the bulk density was up to 1.6-3.1 times compared to the controls, which were not opened to users. As a result, the degradation caused by high users density would keep occurring on the three forest trails unless any counterplans are considered for the degradation reduction. At the moment, users distribution to other forest trails and long-term sabbatical years would be the most effective counterplans to keep from users gravitation on the three forest trails.

  • The purposes of this study were to identify the changes of postprandial blood pressure and pulse rates of elderly living in nursing homes by time and position after a meal. Blood pressure and pulse rates of 141 elderly aged over 65 years were measured at before the meal to 90 minutes after the meal by 15 min. interval. Data were analyzed by descriptive statistics, repeated measures of ANOVA, ANCOVA, and t-test using the SPSS program. There were no significant differences in change of systolic blood pressure and pulse rates by time between sitting group and lying group after meal. The biggest drops in systolic pressure in sitting and lying position were occurred at 30 min and 45min respectively after the meal. There were no significant change in pulse rates except for the immediately after meal in lying position. To prevent complications of postprandial blood pressure reduction, nurses should carefully monitor blood pressure of elderly in lying position at least from 30 min. till to 90 min. after the meal.

  • In this study, a survey was conducted and analyzed to provide basic data on hospital infection control measures and education by identifying awareness and practice of hospital infection control among workers at general hospitals in Busan. As a result of conducting a t-test and one-way ANOVA to see the difference in general variables, the awareness and practice of personal hygiene management were generally low, and the awareness and practice of equipment hygiene management were high. In all areas except for men's personal hygiene management, the level of awareness was higher than the level of practice, confirming that the level of practice was insufficient compared to the level of awareness of infection control. As a result of Pearson's correlation analysis, people with high awareness of infection control showed a high level of practice, so it was thought that raising the awareness of infection control among hospital workers would be effective in preventing hospital infection. Therefore, it is considered that it is necessary to raise the awareness of infection control among workers through continuous education on hospital infection control, and to make efforts of hospital workers to practice it.

  • The subjects of this study were 463 people aged 65 and older in the senior welfare center in Seoul and Gyeonggi. The purpose of the study is to analyze the differences between physical fitness factors and cognitive functions, activities of daily living, instrumental activities of daily living, and psychological variables in the participation of the elderly in physical activities. Data ware analyzed by frequency analysis, reliability analysis, independent sample t-test and one-way ANOVA, and Pearson's correlation analysis, with SPSS 25.0 statistics program. The results of this study are as follows. First, there are statistically significant differences in physical fitness, cognitive function, activities of daily living, instrumental activities of daily living, and psychological factors such as depression and quality of life, depending on whether the elderly participate in physical activity. There were statistically significant differences in physical fitness, cognitive function, ADL, IADL, depression and quality of life, depending on the frequency of participation of older people in physical activity. A statistically significant difference in physical fitness appeared depending on the participation time of the elderly who participated in physical activity. Second, a study of the correlation between physical fitness and cognitive function, ADL, IADL, depression, and quality of life revealed a correlation for most factors. Based on these research results, it is necessary to develop a systematic arbitration strategy including physical activity for the successful aging of the elderly and the independent life of old age.

  • This research studied the effect of visual improvement of "72 Hour Project" that has regenerated small scale derelict spaces in Seoul through citizen participation. 29 projects built form 2016 to 2019 were analyzed. The research analyzed landscape image preference of before and after status of projects using 12 pairs of landscape adjectives. Basic statistical analysis, correlation analysis, factor analysis, cluster analysis, and ANOVA were performed based on the survey results. Since the satisfaction level of the projects compared with the before-condition was 3.63 higher than 3.00, it could be concluded that there was an meaningful effect of visual improvement after completion of the projects. As the result of the factor analysis, landscape adjective pairs were categorized into two factors: harmony and aesthetics. Through the cluster analysis, four clusters were formed and characteristics of each cluster were identified. As the result of rhe cluster analysis, the cluster with the high harmony level and the aesthetics level showed the highest overall satisfaction level. Comparing each cluster, it could be concluded that the factor of harmony was more important than the factor of aesthetics in evaluating the satisfaction level of projects. Analyzing qualitative aspects of project groups, spatially well-balanced design with generous vegetation areas was more effective in landscape improvement than artistic design with visually strong installations. Further researches based on behavior studies of actual users are required to compensate the limits of this research. This research can contribute to establish the improved direction of policies to regenerate various types of small scale derelict spaces.
