Purpose: This randomized controlled trial was conducted to compare the effectiveness of global postural reeducation to segmental stretching in subjects with neck and shoulder pain. Methods: Sixteen subjects with neck and shoulder pain were randomized into two intervention groups, a global posture reeducation group (n=8) that performed muscle chain stretching, and a segmental stretching group (n=8) that performed conventional static muscle stretching. The intervention program consisted of two 40 minutes individual sessions per week for four weeks. Subjects were evaluated pre-intervention, two-week after intervention and at a four-week follow-up appointment for pain intensity, disability and health-related quality of life. Two-way repeated analysis of variance was used for between-time and between-group comparisons. The significance level was 0.05. Results: Significant pain relief and decreasing discomfort of the neck and shoulder were observed after intervention in both groups, and there was an interaction between time lapse and groups (pain, F=10.31, neck disability, F=25.45, shoulder disability, F=12.82, p<0.05). Quality of life also improved after intervention in both groups. Moreover, the physical components score improved, and a significant interaction was observed between time and groups (F=4.85, p<0.05). However, no significant improvement in mental component score of quality of life and no significant interaction between time and groups were observed (p>0.05). Conclusion: These findings suggest that a GPR intervention in subjects with neck and shoulder pain induces greater improvement of pain and disability and quality of life than segmental stretching.

Purpose: The purpose of this study was to identify the influence of depression, optimism and posttraumatic growth on health-related quality of life in female breast cancer survivors received adjuvant chemotherapy. Methods: In total, 115 female breast cancer survivors participated in this descriptive correlational study. The participants answered self-report questionnaires. Data were collected from 1 June 2020 to 10 June 2020, and were analyzed using descriptive statistics, the t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression with SPSS for Windows ver. 24.0. Results: The mean age of the breast cancer survivors was 45.83 years. The mean score for the degree of health-related quality of life was 81.85 out of 148 points. Participants' scores for health-related quality of life differed significantly based on economic status (F=5.36 p=.006) and hobbies (t=-3.37, p=.001). Health-related quality of life was negatively correlated with depression (r=-.73, p<.001), and positively correlated with optimism (r=.65, p<.001) and posttraumatic growth (r=.28, p=.002). Depression (𝛽=-.55, p<.001) was the most significant factor that affects health-related quality of life, followed by optimism (𝛽=.29, p<.001), and post-traumatic growth (𝛽=.12, p=.048), which together accounted for 62.2% (F=63.61, p<.001) of the variance. Conclusion: It is necessary to develop educational programs for breast cancer survivors to reduce depression, increase optimism and post-traumatic growth, and improve the health-related quality of life. By adapting these programs, positiveness may increase and this may lead to improvement of health-related quality of life for breast cancer survivors.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.

Purpose: The purpose of this study was to evaluate the effects of client-centered art and craft activities on depression and quality of life in stroke clients. Through this, we aim to find a way to reduce depression and improve the quality of life in stroke clients. Methods: Clients diagnosed with stroke were selected as participants for the study. Participants in the experimental group (n=13) and control group (n=14) received general occupational therapy. Clients in the experimental group participated in client-centered art and craft activities, whereas clients in the control group participated in general art and craft activities for 8 weeks. Beck Depression Inventory(BDI) and Stroke Specific Quality of Life(SS-QOL) were used to evaluate the depression and quality of life of the clients before and after the intervention. Results: The experimental group and control group presented significant statistical difference in depression before and after intervention (p<.01; p<.05). The experimental group showed a greater decrease in depression (p<.05) than the control group. Additionally, the experimental and control group displayed significant statistical difference in quality of life (p<.01) before and after intervention. The experimental group showed a more statistically significant improvement in quality of life (p<.01) than the control group. Conclusion: These results demonstrate the significance of client-centered art and craft activities in reducing depression and improving quality of life in clients with stroke. Therefore, it is expected to be useful in clinical settings. Occupational therapy should be provided based on the decision of the clients.

The purpose of this study was to examine the understanding and perception of 'community welfare', a domain of social welfare. First of all, we used the Q methodology, a qualitative research, to typology the recognition of community welfare. For the analysis, we have obtained various terms (Q samples) that have been discussed and learned in the community welfare, and examined the types of recognition of these terms. For the analysis, 29 samples of 29 samples were obtained from 29 samples of P samples. As a result of analysis, three types were defined. In other words, emphasizes 'participation of residents', 'building ties', and 'improvement of life quality of residents' is named it "Quality of residents life-Relationship Type". emphasizes 'improvement of quality of life of residents' and 'satisfaction of community needs' and named it "Quality of residents life- Desire for community needs Type". emphasizes 'participation of residents' and 'improvement of quality of life of residents' and named it "Participation of Residents-Quality of Life Type". The respondents' characteristics according to type, it was found that there was a difference in recognition of community welfare by individual characteristics. So, we hope to enhance the usefulness of the hypothesis abductive approach and to extend the study to future quantitative research.
