The purpose of the present study was to examine socio?demographic and health?related characteristics associated with awareness of the Long?term care insurance system in Korean older adults. Methods: The survey included items on awareness of the Long?term care insurance system as the dependent variables, and physical activity levels, self?rated health status, awareness of long?term care prevention and demographic variables as the independent variables. Logistic regression analysis revealed that having a higher level of education (OR = 2.60; 95% CI = 1.47 ? 4.53), having higher subjective feelings of health (OR = 0.22; 95% CI = 0.12 ? 0.39), having a higher level of physical activity (OR = 2.78; 95% CI = 1.30 ? 5.73) were associated with the awareness of the Long?term care insurance system. The present study shows that respondents who are aware of the Long?term care insurance system are more likely to have higher subjective feelings of health and higher levels of physical activity. To promote the Longterm care insurance system on future, action plans for the unawareness group is needed. Moreover, formulating strategies in promoting the participation of non?profit group is necessary.

Objective: The purpose of the present study was to examine the relationship between the use of senior center and health-related quality of life in Korean older adults. Methods: A questionnaire survey was conducted to two types of older adults who lived in Busan, Korea: 154 older adults who used a senior center and 137 older adults who did not use a senior center. The Korean version of short-form 36-item health survey was administered to assess the health-related quality of life. Demographic variables were obtained from a questionnaire. These were gender, age, family status, marital status, education, monthly income, present illness, body mass index and physical activity. Results: The 8-domain scales of physical function and role-physical were significantly higher in the users of the senior center compared with the non-users (F=4.87, p=0.027 and F=7.02, p=0.009, respectively). The 8-domain scales of vitality was also significantly higher in the users of the senior center compared with the non-users (F=7.48, p=0.007). Conclusions: The present study showed that the users of the senior center have higher physical function, role-physical and vitality compared with the non-users. These findings suggest that although the results are unable to specify causal relationships using the senior center may lead to some improvement in health-related quality of life.

Objectives: The purpose of the study was to examine the relationships among the psychological, social, and environmental factors influencing the utilization of senior centers among older adults in Korea. Methods: A questionnaire survey was administered to two types of older adults who lived in Seoul, Korea: 262 older adults who used senior centers (3 places) and 156 older adults who did not use senior centers. Results: Our results showed clearly that the utilization of the senior centers in Korea is affected by higher self-efficacy (odds ratio [OR], 6.08; 95% confidence interval [CI], 3.31 to 12.32), higher perceived benefits (OR, 1.71; 95% CI, 1.16 to 4.36), lower perceived barriers (OR, 6.43; 95% CI, 3.07 to 11.45), higher family support (OR, 4.21; 95% CI, 2.02 to 8.77), and higher support from friends (OR, 4.08; 95% CI, 2.38 to 7.81). The results also showed that participants whose total travel time was 15 to 29 minutes (OR, 2.84; 95% CI, 1.21 to 3.64) or less than 14 minutes (OR, 4.68; 95% CI, 3.41 to 8.41) were more likely to use a senior center than those who had to travel more than 30 minutes. Conclusions: This study showed that the utilization of senior centers in Korea is affected by psychological, social, and environmental factors, specifically by self-efficacy, perceived benefits, perceived barriers, social support, convenience of transportation, and total travel time to the senior centers. The effects of longer-term utilization of the senior centers by non-users on health-related outcomes in a large population warrant attention.

Pseudomonas syringae pv. tabaci 6605 has two mul- tidrug resistance (MDR) efflux pump transporters, MexAB-OprM and MexEF-OprN. To understand the role of these MDR efflux pumps in virulence, we generated deletion mutants, ∆mexB, ∆mexF, and ∆mexB∆mexF, and investigated their sensitivity to plant-derived antimicrobial compounds, antibiotics, and virulence. Growth inhibition assays with KB soft agar plate showed that growth of the wild-type (WT) was inhibited by 5 μl of 1 M catechol and 1 M coumarin but not by other plant-derived potential antimicrobial compounds tested including phytoalexins. The sensitiv- ity to these compounds tended to increase in ∆mexB and ∆mexB∆mexF mutants. The ∆mexB∆mexF mutant was also sensitive to 2 M acetovanillone. The mexAB- oprM was constitutively expressed, and activated in the ∆mexF and ∆mexB∆mexF mutant strains. The swarming and swimming motilities were impaired in ∆mexF and ∆mexB∆mexF mutants. The flood inocula- tion test indicated that bacterial populations in all mu- tant strains were significantly lower than that of WT, although all mutants and WT caused similar disease symptoms. These results indicate that MexAB-OprM extrudes plant-derived catechol, acetovanillone, or cou- marin, and contributes to bacterial virulence. Further- more, MexAB-OprM and MexEF-OprN complemented each other’s functions to some extent.
