Objectives: This study is to examine that drinking problems among university students were accounted for not only by student's individual characteristics but alcohol policy and environmental characteristics of the university in which students were enrolled. Method: Secondary data analysis was employed in which variables under study were derived from a raw data of a nationwide representative sample in 2009. Raw data under analysis included 3,665 students from 63 universities across Korea. Organizational and environmental characteristics of the university were collected from university administrators while individual characteristics and drinking behavior from the students in using self-administrated questionnaire. Multilevel regression analyses were employed to describe alcohol policy effects on students's drinking problems measured by AUDIT by using HLM7.0. Results: ICCs indicate that variation in drinking problem depends on alcohol policy of university. Multilevel regression models identified statistically significant factors in explaining variance of drinking problems. Group means on drinking problem are affected by indicators representing alcohol policy with level of drinking problem of student being decreased in accordance to level of availability of alcohol on campus. Conclusions: It is concluded that drinking problems among university students were associated with both individual characteristics and alcohol policy of the university they enrolled. This study supports policy belief that interventions at environmental as well as individual level are required to prevent drinking problem among university students.

Background: Physical activity (PA) is critical for maintaining the health and well-being of older people in community and also institutional settings. The purpose of this study was to examine the current status of PA and related individual and organizational factors among older nursing home residents with and without dementia. Methods: This is a secondary data analysis study of a nationwide survey of 92 long-term care facilities in Korea, and the study sample includes older residents with dementia (n= 753) and without dementia (n= 480). The level of PA was measured by PA time and whether or not residents had an outdoor activity over the past 3 days. Multi-variate, multi-level analyses were conducted. Results: More than half of the sample in both groups had no or less than 1 hour of PA. About one out of four older people in our sample had no outdoor activity over the past 3 days regardless of whether or not they had dementia. Among the people without dementia, several individual-level factors were associated with PA, including dependency for activities of daily living, social activity participation, and caregivers' belief in the functional improvement of residents. Unlike the non-dementia group, individual- and organizationallevel factors including staffing level and having the relevant equipment for PA were associated with PA among those with dementia. Conclusion: Study findings provide evidence on the lack of PA among older nursing home residents, and the importance of institutional capacity with regard to human resources and physical equipment for promoting PA among people with dementia, in particular. Policies and supports are needed to promote the implementation of healthy aging programs including PA for older nursing home residents. Such programs should be person-centered with consideration to the physical and cognitive status of individual residents.

Objectives: This study divided the factors that affect participation in health screenings into individual, household, and regional levels and conducted a multi-level analysis to identify the factors related to participation in health screenings. Methods: Participants from the 2017 Community Health Survey were classified into 2 groups (under 40 and 40 or older). A multi-level logistic regression analysis was conducted to identify the factors that affected participation in health screenings. Results: The screening rate of the participants was 69.7%, and it was higher among participants aged 40 and older (80.3%) than it was among participants younger than 40 (49.8%). At the individual level, the factors that influenced participation in health screenings included age, economic activity, smoking status, physician-diagnosed hypertension, and a moderate or high physical activity level. At the household level, the odds ratio of participation in health screenings was high for participants who lived in single-person households, lived with a spouse, earned a high monthly household income, and were not beneficiaries of national basic livelihood security. At the regional level, the odds ratio at the 95% confidence interval level of participation in health screenings was high for participants who had trust in the local community and lived in an area with a proportionally high social welfare budget. Conclusions: This study analyzed nationalwide data and confirmed that individual, household, and regional characteristics affected participation in health screenings. Therefore, policies that prioritize the improvement of regional level factors and especially household level factors are likely to be the most effective for improving the screening rate.

As the business environment becomes more rapid and unpredictable change, greater diversity, increased complexity, and intensified competitive pressures, supply chain risk management has been growing attention over the past several decades. However, little of known about how absorptive capacity can mitigate supply chain risk for improving operational performance despite its important role in responding to supply chain risk. Therefore, we aim to examine the role of organizational-level absorptive capacity on operational performance, and further identify how the interplay of individual-level and organizational-level absorptive capacity results in operational performance. Our results represent not only direct but also indirect effects of supply chain risk on operational performance, mediated by organizational-level absorptive capacity. Furthermore, this study reveals that individual-level absorptive capacity enhances the effect of organizational-level absorptive capacity on operational performance.

Objectives : The aim of this study is to investigate the various effects of individual or combined extract of GamiSaengmaeksan (GSS) on cell viability, anti-inflammatory and antioxidant activityMethods : In order to evaluate cytotoxicity, MTT assay was performed. We investigated the levels of proinflammatory cytokines such as tumor necrosis factor (TNF)-α and interleukin (IL)-6 and interleukin (IL)-1β, and nitric oxide(NO) in LPS-induced RAW 264.7 cells to check the effects on anti-inflammatory activity. The level of NO production in RAW 264.7 cells was measured by using Griess reagent. The levels of cytokines and ROS were measured by Luminex and Flow cytometry, respectively.Results : At concentration of 200 ㎍/㎖ GSS, cytotoxicity was observed in RAW 264.7 cells. However, at concentration less than 100 ㎍/㎖ of both combine and individual GSS, cytotoxicity was not observed in Raw 264.7 cells. However, the level of ROS in RAW 264.7 cells were decreased at both extract of 100 ㎍/㎖ GSS. Also, the level of NO in RAW 264.7 cells were decreased from extraction of concentration of 100 ug/ml in GSS and individual-extraction of Liriopis Tuber, White Ginseng and Glycyrrhizae Radix. In addition, productions of pro-inflammatory cytokines (TNF-α) in LPS-induced RAW 264.7 cells were decreased from extraction of concentration of 10 and 100 (㎍/㎖) in GSS and individual-extraction of Liriopis Tuber.Conclusions : It is concluded that combined extract of GSS appears to be more effective in anti-oxidation and anti-inflammatory effect than those in individual-extraction of GSS. These results may be developed as a raw material for new therapeutics to ease the symptoms related with inflammatory and oxidative stress.

Background: In this study, we aimed to investigate the interaction effects of individual socioeconomic status and regional deprivation on the onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients. Methods: Korean National Health Insurance Service National Sample Cohort data from 2002 to 2013 were used. A total of 50,954 patients newly diagnosed with type 2 diabetes from 2004 to 2012 and aged 30 years or above were included. We classified patients into six groups according to individual income level and neighborhood deprivation: 'high in advantaged,' 'high in disadvantaged,' 'middle in advantaged,' 'middle in disadvantaged,' 'low in advantaged,' and 'low in disadvantaged.' We calculated hazard ratios (HR) of onset of diabetes complication and diabetes-related hospitalization using the Cox proportional hazard model, with the reference group as diabetes patients with high income in advantaged regions. Results: In terms of the interaction effects of individual income level and regional socioeconomic level, even with the same low individual income level, the group with a high regional socioeconomic level (low in advantaged) showed low HRs for the onset of diabetes complication (HR, 1.04; 95% confidence interval [CI], 1.00-1.08) compared to the 'low in disadvantaged' group (HR, 1.10; 95% CI, 1.05-1.16). In addition, the 'high in advantaged' group showed slightly higher HRs for the onset of diabetes complication (HR, 1.06; 95% CI, 1.00-1.11) compared to the 'low in advantaged' and it appeared to be associated with slight mitigation of the risk of diabetes complication. For the low-income level, the patients in disadvantaged regions showed the highest HRs for diabetes-related hospitalization (HR, 1.29; 95% CI, 1.19-1.41) compared to the other groups. Conclusion: Although we need to perform further investigations to reveal the mechanisms that led to our results, interaction effects individual socioeconomic status and regional deprivation might be associated with on onset of diabetes complications and diabetes-related hospitalization among type 2 diabetes patients.
