PURPOSE: The aim of this study is to examine a path model on the relationship among social capital, physical activity and subjective health status in the community indwelling elderly. METHODS: The study was conducted utilizing the 2014 Seoul Survey, in the method of analyzing cross-sectional design and secondary data. Among 45,497 participants in total, the data of 4578 adults aged 65 or above was analyzed. Social capital was measured by social trust and social participation. Physical activity was measured by regular exercise. Additionally, a numerical rating scale was used to assess subjective health status. The data were analyzed using descriptive statistics, Pearson's correlation coefficients and path analysis. RESULTS: Social participation and physical activity showed a direct effect on subjective health status in community indwelling elderly while social trust and physical activity showed an indirect effect on their subjective health status. The hypothetical path model of community indwelling elderly's subjective health status was proved correct. CONCLUSION: Findings from this study indicate that health-promoting intervention for community indwelling elderly should consider social trust and participation.

Purpose: The aim of this study was to identify differences and influencing factors in the level of life satisfaction among the urban community-dwelling elderly by age group. Methods: The study was conducted utilizing the secondary data of 2017 Seoul Survey in a cross-sectional design. Of 42,688 participants in total, the data of 7,927 adults aged 65 or older were analyzed. The data were analyzed using descriptive statistics, independent t-test, chi-square test, Pearson’s correlation coefficients, and multiple linear regression. Results: There were significant differences between age groups, and it was found that the old elderly groups had significantly higher life satisfaction than the oldest elderly group (t=8.37, p<.011). In common, family and community factors influencing life satisfaction in the two age groups were companion animals (old elderly: β=.03, p=.002; oldest elderly: β=.06, p=.021), social network (old elderly: β=.10, p<.001; oldest elderly: β=.08, p=.008), and social support (old elderly: β=.05, p<.001; oldest elderly: β=.08, p=.005). Conclusion Based on these results, social welfare and nursing care services focusing on social capital and age group-specific interventions are needed to improve life satisfaction of the elderly. This study might provide the possibility and evidence for a program to improve life satisfaction for the urban community-dwelling elderly, including social capital elements.

Purpose: The number of older adults with dementia who reside in long-term care institutions has significantly grown. When older adults with dementia are institutionalized, their spouses, who were providing care at home, may experience chronic mental health conditions. This study examined and compared the mental health status of older adults who institutionalized their spouses with dementia in long-term care institutions versus that of older adults who reside with their spouses in their homes. Methods: The analysis included 95 spouses of institutionalized individuals and 285 control group participants, drawn from 63,617 participants of the 2018 Korean Community Health Survey. Results: The results showed that the spouses of institutionalized individuals with dementia had more depressive symptoms, poorer sleep quality, and experienced greater stress than those in the control group. Conclusion It is necessary to provide supportive care, for alleviating depressive symptoms, poor sleep quality, and stress, to individuals whose spouses are residing in long-term care facilities. For a spouse caregiver, navigation help and education on the changing roles after an older adult’s admission to a long-term care facility would be necessary.

PURPOSE: The purpose of this study was to identify factors influencing psychosocial well-being in family caregivers of patients with amyotrophic lateral sclerosis (ALS). METHODS: A descriptive correlational design was used. The transactional model of stress and coping was used to investigate the psychosocial well-being of 137 family caregivers of patients with ALS. Data were collected through self-reported questionnaires from January to November 2016. Data were analyzed using an independent t-test, one-way ANOVA, Pearson's correlation, and hierarchical multiple regression analysis with the SPSS WIN 21.0 program. RESULTS: The regression model had an adjusted R2 of .49, which indicated that meaning-focused coping, social support, ALS patient-family caregiver relationship (especially a spousal relationship), and tracheostomy were significant predictors of caregivers' psychosocial well-being. CONCLUSION: Meaning-focused coping and social support significantly influenced caregivers' psychosocial well-being. Therefore, interventions to improve caregivers' psychosocial well-being must focus on increasing meaning-focused coping and social support resources.

Recombinant DNA vaccines, based on plasmid vectors expressing an antigen under the control of a strong promotor, have several advantages over traditional vaccines. They have been shown to induce a full spectrum of immune responses for humoral and cellular systems and to secure the higher safety and the simplicity of administration. Thus, establishment of DNA vaccines against Newcastle disease virus (NDV) in poultry has been widely investigated using various virus strains and vector systems. In this study, the F and HN genes of NDV CBP-1 strains isolated from diseased pheasants and attenuated by serial passages in egg embryos were cloned using pSLIA vector and constructed two recombinants of pSLIA-tsF and pSLIA-tsHN. The recombinant plasmids were transfected into COS-7 cell and the expression of HN and F proteins were verified by immunofluorescence, SDS-PAGE and Western blot. The recombinant plasmids were injected intramuscularly and intradermally into C57B/6 mouse and a significant increment of HN and F antibodies was detected by ELISA. According to the results, it was implicative that the recombinant DNA could be utilized for development of recombinant DNA vaccine for NDV.

Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.
