Purpose
The incidence of diabetes mellitus (DM) rises significantly in the post-middle-age population, and stress along with depressive symptoms hinders effective DM management. This study examined the mediating effect of social capital (trust in the physical environment, reciprocity, social participation, and social networks) on the relationship between perceived stress and depression among middle-aged adults with DM in Korea. It also aimed to provide data for developing targeted interventions to enhance blood glucose management in this population.
Methods
A descriptive correlational study using data from the 2019 Community Health Survey by the Korea Disease Control and Prevention Agency (KDCA) was conducted. Complex sample regression analysis and the Sobel test were employed for mediation analysis. The study included 9,394 middle-aged adults (aged 45-64 years) diagnosed with DM. The analysis assessed the effects of perceived stress on social capital and depression, as well as the mediating role of social capital.
Results
Perceived stress negatively impacted social capital (β=-0.16, p<.001) and positively influenced depression (β=0.37, p<.001). Both perceived stress and social capital significantly affected depression (F=998.83, p<.001), with social capital showing a partial mediating effect (z=2.65, p<.001).
Conclusion
Social capital partially mediated the relationship between stress and depression, suggesting its potential as a strategy for reducing stress and lowering depression among middle-aged adults with DM. These findings lay the groundwork for targeted interventions to improve blood glucose management in this population. Future research should explore the relationships among specific components of social capital, stress, and depression.

PURPOSE
This study was performed to identify the relationship between Sense of Humor, Coping Humor, Perceived stress and self-esteem in the middle-aged women. METHODS: Data were collected from the 20th of June to the 30th of August in 2009 from 145 middle-aged women living in Seoul.

RESULTS: The mean score of the humor sense was 55.94+/-6.52, coping humor was 21.11+/-3.82, perceived stress was 22.21+/-3.03 and self-esteem was 27.50+/-2.88. Subcategories of sense of humor were that emotional expressiveness was average 20.75+/-2.70, meta-message sensitivity was average 20.12+/-2.74 and liking of humor was average 15.13+/-3.44. Sense of humor was difference according to the economic status(t=2.000, p=.047), coping humor was difference according to the on medication use(t=2.227, p=.027). There was a significant correlation between the coping humor, perceived stress and the self-esteem. When the coping humor was higher, perceived stress was lower and the self-esteem was higher. CONCLUSION: This study showed that medication and economic status influences the humor scores and the sense of humor and coping humor were related to perceived stress and self-esteem in middle-aged women Therefore, these findings can provide the basis for the development of nursing intervention to increase the ability to coping with stress.

PURPOSE
This study is descriptive study that confirms the affect of the factors of perceived stress and social support of the kidney transplantation recipient affect on the quality of life.
METHODS
167 subjects who have received kidney transplantation in a university hospital in G city. Data obtained are analyzed by SPSS Win 13.0.
RESULTS
The perceived stress based on transplantation related characteristics and general traits of kidney transplantation has significant differences only in frequency of admission. The subjects who had been supported by acquittances have more significant social support index. The quality of life has significant differences in number of admissions, gender and occupation. Also, when the perceived stress of kidney transplantation recipients is lower and social support is higher, the quality of life is higher. The perceived stress has 28.1% increment of quality of life. Adding social support, both of them affect 34.8% increment of quality of life.
CONCLUSION
To decrease the factor to cause the stress of kidney transplantation recipients, it is necessary to have social support networks and to develop plans and programs to increase the quality of life of recipients.
