Purpose: This study was a descriptive correlation research designed to provide basic data on family nursing interventions by examining burden, social support and quality of life for family caregivers of patients on hemodialysis. Methods: Data were collected from 132 family caregivers of patients on hemodialysis and analyzed using frequency analysis, correlation analysis, independent samples t-test method, one-way ANOVA and post-hoc analysis of $Scheff{\grave{e}}$, and multiple regression analysis. Results: Burden for family caregivers of patients on hemodialysis was 3.03, social support, 4.77, and quality of life, 3.26. Burden showed a negative correlation with social support (r=-.34, p<.001), and with quality of life (r=-.54, p<.001). There was a positive correlation between social support and quality of life (r=.54, p<.001). Factors predicting quality of life for family caregivers, were a significant and positive effect from social support (t=5.72, p<.001) and a negative effect from family burden (t=-5.62, p<.001). Conclusion: Results of the study indicate that burden of these family caregivers can be reduced by social support which plays an important role in improving quality of life. A nursing intervention program which goes beyond simply caring for patients and includes assessment of family burden and support for overall family caretaking needs to be developed.

Obecity in pregnancy causes many problems and increases risk of pregnancy complications at the time of childbirth. But there is a lack of comprehensive analysis of factors that are negatively affected during pregnancy. Therefore, this study is intended to analyze seven factors of high-risk maternal diseases by the degree of obesity using body mass index(BMI). We conducted a cross tabulation analysis and regression analysis to analisized relationship between variables : Gestational Hypertension(GH), Gestational Diabetes Mellitus(GDM), Thyroid Stimulation Hormone(TSH), Age, Blood Urea Nitrogen Test(BUN), Total-Cholesterol(T-C), and newborn's weight. As a result, the more the obesity level of mothers increases, the more the proportion of mothers with GH, GDM, TSH increases. And there was a positive relationship between the BMI of mothers and their age, T-C, and Newborn weight, and a negative relationship to the BUN.

The main purpose of this study was to examine the correlation between the consumption of red ginseng-based 'SSR' for 30 days and the reduction in human fatigue, blood component changes, and immune cell activity in 35 human subjects. 'SSR' is composed of zinc oxide, folic acid, and D-α-tocopherol with red ginseng as the main component. According to the protocol criteria of the study, 35 subjects who understood the purpose of the study and signed an informed consent form were selected. The fatigue survey was conducted through a questionnaire, and after taking 'SSR', a decreased tendency of physical, mental, and neurosensory fatigue was observed. In hematological analysis, no significant changes were observed in the levels of WBC, RBC, and hemoglobin; however, AST (SGOT) and ALT (SGPT) levels were statistically significantly decreased. In immunological analysis, it was observed that the proliferative effect of T cells (CD3+CD4+) was greater than that of NK cells (CD16+CD56+). The collected data were subjected to t-test analysis using the SPSS 25.0 statistical program. The result from this study proposes that 'SSR' can be used as a functional food material as it reduces human fatigue and enhances immune function.

Purpose: This study aimed to develop a scale to measure distress in patients with ischemic stroke and verify its validity and reliability. Methods: Preliminary items were developed from literature review and in-depth interviews. The final preliminary scale was confirmed through a content validity test of eight experts and a preliminary survey of 10 stroke patients. The participants for psychometric testing were 305 stroke patients in the outpatient clinic. Validity and reliability analyses included item analysis, exploratory and confirmatory factor analysis, convergent validity, known-group validity, and internal consistency of the scale. Results: The final scale consisted of 17 items and 3 factors. The three distinct factors were 'self-deprecation, worry about future health, and withdrawal from society' and this structure was validated using a confirmatory factor analysis. Convergent validity was supported by comparison with the Center for Epidemiologic Studies Depression Scale (r = .54, p < .001) and Brief Illness Perception Questionnaire (r = .67, p < .001). Known-groups validity was verified by dividing groups according to 'duration since diagnosis' (t = 2.65, p = .009), 'presence of sequela' (t = 10.16, p < .001), and 'awareness of distress' (t = 12.09, p < .001). The internal consistency of the scale using Cronbach's α for the total items was .93. Conclusion: The Ischemic Stroke Distress Scale is a valid and reliable tool that reflects stroke distress effectively. It is expected to be used as a basic tool to develop various intervention strategies to reduce distress in ischemic stroke patients.

Background: Dental hygienists provide direct dental care in the closest proximity to the patient, and each practice requires a high level of focus and concentration. These skills are an important human resource that can impact the quality of dental care services. Since more than half of dental clinics provide as overtime work in addition to regular hours, this study aims to determine the association between working overtime and job performance for dental hygienists. Methods: The study was conducted using a combination of online and in-person surveys via Google Forms among 131 employed dental hygienists. The survey consisted of 7 questions on demographic and work characteristics, 16 questions on characteristics related to overtime and the effect of overtime on job security, health, and life, and 10 questions on job performance, for a total of 33 questions. Chi-square analysis and independent samples t-test were used to identify the characteristics of demographic and work characteristics, and descriptive statistics analysis was used for the characteristics of overtime. Independent samples t-test was used to test the difference in the mean of job performance according to whether or not they worked overtime, and linear regression analysis was used to show the association of working overtime and job performance. Results: The study found that 71% of dental clinics worked overtime. The average number of overtime per week was once (78.5%), and the most common problems with overtime were fatigue (52.7%) and lack of personal and leisure time (41.9%). The appropriate number of overtime per week considered by dental hygienists was once a week, which was confirmed to be 94.6%. When comparing job performance by overtime status, those who worked overtime were 3.38 points higher than those who did not (35.45 vs. 32.07). Multiple linear regression analysis of the association of working overtime night and job performance showed that a one-unit increase in worked overtime was associated with a statistically significant increase in job performance of about 3.1 (p<0.01). Conclusion: Working overtime was found to have a positive effect on job performance among dental hygienists. Therefore, as a way to improve the working environment, providing appropriate compensation or welfare for overtime can reduce the negative aspects of overtime and turn it into a positive influence on job performance. This could ultimately raise awareness of the dental hygienist as a professional and effect the efficiency of dental care services.

The purpose of this study was to examine the anxiety, levels of diabetes-related distress, and post-traumatic growth of parents who have children with type 1 diabetes and determine the correlation between the differences and variables based on the general characteristics and disease-related characteristics. This is a descriptive survey research and data collection was conducted from January 4th-29th of 2016 with an online survey in an internet community for type 1 diabetes. Seventy seven individuals were included in the final analysis. Statistical analysis was carried out with a t-test, Mann-Whitney U test, Kruskal-Wallis test, and Pearson correlation coefficient. The study results showed that posttraumatic growth was significantly high (p<.05) under parents with a religion, and that parental anxiety and stress were high with children under 6 years of age (p<.05), with cases of hypoglycemia (p<.05), and with high levels of glycated hemoglobin (p<.05). Anxiety and stress had a positive correlation (r=.684, p<.001), and anxiety and stress exhibited a negative correlation with posttraumatic growth (r=-.401, p<.001; r=-.327, p<.05). This suggests that posttraumatic growth can reduce the negative emotions sufficiently, and that a mediating mechanism is needed that promotes posttraumatic growth while decreasing the level of anxiety and stress.

Purpose: The purpose of this study was to investigate screw joint stability and sagittal fit between internal connection implant fixtures of two different manufacturers and customized abutments. Materials and methods: Internal connection implant systems from two different manufacturers (Biomet 3i system, Astra Tech system) were selected for this study (n=24 for each implant system, total n=48). For 3i implant system, half of the implants were connected with Ti ready-made abutments and the other half implants were connected with Ti CAD-CAM custom ones of domestic-make (Myplant, Raphabio Co., Seoul, Korea) and were classified into Group 1 and Group 2 respectively. Astra implants were divided into Group 3 and Group 4 in the same way. Micro-CT sagittal imaging was performed for fit analysis of interfaces and preloading reverse torque values (RTV) were measured. Results: In the contact length of fixture-abutment interface, there were no significant differences not only between Group 1 and Group 2 but also between Group 3 and Group 4 (Mann-Whitney test, P>.05). However, Group 2 and Group 4 showed higher contact length significantly than Group 1 and Group 3 in abutment-screw interface as well as fixture-screw one (Mann-Whitney test, P<.05). In addition, RTV was lower in CAD-CAM custom abutments compared to ready-made ones (Student t-test, P<.05). Conclusion: It is considered that domestically manufactured CAD-CAM custom abutments have similar fit at the fixture abutment interface and it could be used clinically. However, RTV of CAD-CAM custom abutments should be improved for the increase of clinical application.
