  • This study examined artificial joint replacement surgery for early intervention and prevention of the occurrence of delirium surgery. Data of study were analysed using the sample through the EMR (Electronic Medical Record) and after surgery to provide basic data. The subjects were elderly aged 60 years or more and the number of the sample was 821. Data were analysed by using SPSS 20.0 with t-test, $x^2$-test and multiple logistic regression analysis. The study results showed patients with artificial joint replacement surgery incidence of delirium was 13.5%, findings of these variables insisted that the main influencing factors of delirium were caused by age, fall history, physical activity, emotional status, body mass index (BMI) before surgery. The study suggested that the above findings are required for early intervention, early detection and prevention of delirium.

  • This study investigates the influence of project-based learning method on the problem-solving ability and communication ability of students taking the 'Reading Guide' course in Library and Information Science(LIS). During this study, two tests measuring students' problem-solving ability and communication ability were conducted, containing 30 items divided into 5 steps of problem-solving processes and 45 items divided into 15 categories of communication ability, respectively. By utilizing the correspondence sample T-test during this study, significant differences were found in the 5 steps problem-solving processes. However, no difference was found between the pre-test and the post-test results in all 15 categories of communication ability. Subsequently, an in-depth interview was conducted, inquiring into the students' perspectives on the difficulty of attending classes, the content of lectures, the appropriateness of assignments, the validity of the evaluation method, the relationship with their team members, and the benefits acquired from completing the projects. Finally, an intensive analysis was conducted in the categories of problem-solving ability and communication ability.

  • The purpose of this study was to explore the differences of the metacognitive awareness of reading strategies which gifted English language learners (GELLs) and general middle school learners (GMSLs) used while reading English test-typed texts. 74 GELLs in a gifted program of C city and 90 GMSLs in the southern part of C city participated in this study. The MARSI questionnaire was administered to the GELLs and GMSLs at the end of the semester. Frequency and t-test were used to examine the differences in metacognitive awareness of reading strategy use between GELLs and GSMLs when reading the English test-typed texts. Based on the analysis, the study discovered that GELLs were likely to use metacognitive awareness of reading strategies more frequently than GMSLs. Also, GELLs tended to use more global and problem-solving strategies than GMSLs. However, there is no significant difference in support strategy use between the two groups. In conclusion, the study suggests pedagogical implications for GELLs and GMSLs' effective English reading.

  • Purpose: Obesity affects dysfunction of Hypothalamus-Pituitary-Ovary(H-P-O) axis. Dysfunction of H-P-O axis could be related to Skin Resistance Variability (SRV). This study investigated the impacts of obesity which related to female age on SRV. Methods: We randomly selected 400 women who had taken CP-6000A test and InBody test on the same day at Oriental Hospital of Sangji University from Jan. 2008 to Jun. 2011. In this study, the Body Mass Index(BMI) range of normal group is 18.5~24.9, obesity group is over 25, the age range of childbearing age group is 24~34 years, post-menopause group is 50~65 years. 139 women that met the criteria of this study were assorted by their BMI and age. After detection of SRV, SPSS 19.0 has conjugated for data analysis and the independent samples t-test and paired samples t-test were used to verify the results. Results: At 1st and 2nd trial, the height of 3 area of childbearing age obesity group was significantly higher than that of childbearing age normal group. At 1st and 2nd trial, the height of 1, 2 area of childbearing age obesity group was higher than that of childbearing age normal group, but there were no significant difference. At 1st and 2nd trial, the height of 1, 2, 3 area of post-menopause obesity group was mostly higher than that of post-menopause normal group, but there were no significant difference. Conclusions: This study showed the SRV of obesity group was higher than that of normal group in most of 1, 2, 3 area. Further study will be needed.

  • The purpose of this study was to investigate the factors affecting clinical competence on early stage nurse working in a general hospital. Data were collected by questionnaires on early stage nurses from september 11 to september 30, 2020. Data were analyzed by t-test, ANOVA, Scheffe test, Pearson correlation coefficients and multiple regression analysis, using SPSS WIN program. The degree of dysmenorrhea was 2.77 points, clinical competence was 3.44 points. Dysmenorrhea was negative correlated with clinical competence(r=-.226, p=.002). Response of autonomic nervous system was identified as factors influencing clinical competence(𝛽=-.261, p= .001). The model explained 22.1% of the variables. These results suggest that we need intervention education program for response of autonomic nervous system in order to improve the clinical competence of early stage nurses.
