Purpose: This study was conducted to identify factors associated with high-risk drinking in Korean men. Methods: This study was a secondary analysis using data from the Korea National Health and Nutrition Examination Survey (KNHANES VIII-2), 2020. Data were downloaded from the KNHANES website. The subjects of this study were 1,653 alcohol-drinking men between 19 and 64 years of age. Data were analyzed using the Rao-Scott chi-square test and complex sample logistic regression statistics. Results: The high-risk drinking rate among alcohol-drinking men was 27.1%. High-risk drinking was more common in men who smoked (odds ratio [OR] = 2.11, p < .001), men with a middle school education or lower (OR = 1.91, p = .016), men who lived with a spouse (OR = 1.61, p = .025), men who slept less than 6 hours on weekends (OR = 1.51, p = .016), and men who perceived stress (OR = 1.30, p = .044), while it was lower in men who were underweight (OR = 0.19, p = .006). Conclusion: To reduce the rate of high-risk drinking, it is necessary to provide an intervention that considers factors associated with high-risk drinking among men. In particular, smoking was the most important factor associated with high-risk drinking, implying that the integrated management of drinking and smoking is necessary to reduce high-risk drinking.

Chronic joint pain due to loss of cartilage function, degradation of subchondral bone, and related conditions are common plights of an arthritis patient. Antioxidant compounds could solve the problems in arthritic condition. The objective of this study was to evaluate the anti-arthritic activity of D-carvone against complete Freund's adjuvant (CFA)-induced arthritis in rats. D-carvone was orally administered for 25 days at the doses of 30 and 60 mg/kg against CFA-induced arthritic rats. Changes in body weight, paw swelling, organ index, hematological parameters, oxidative stress markers, inflammatory cytokines, and histopathology were recorded. Oral treatment of D-carvone significantly improved the body weight, reduced the paw swelling, edema formation, and organ index in arthritic rats. The levels of white blood cells were reduced, red blood cells and hemoglobin levels were improved in D-carvone treated arthritic rats. Lipid peroxidation levels were lowered whereas enzymatic and non-enzymatic antioxidants were significantly elevated by D-carvone administration against arthritic rats. D-carvone significantly modulated inflammatory cytokine levels and improved the ankle joint pathology against CFA-induced arthritic inflammation. In conclusion, D-carvone proved significant anti-arthritic activity against CFA-induced arthritis in rats.

The current study was conducted to produce basic data for the policy establishment to improve the life satisfaction of residents in regional communities. The study subjected total 1,400 residents living in youngnam province in our nation for the survey by using convenience sampling. The survey took about 4 months started from March 1, 2007 to June 30, 2007. The abstract and conclusion of the result could be summarized as in below. 1. In subjective health status, 45.4% responded as normal, and the health status scored $2.68{\pm}0.67$ in 5 point scale(53.6 in 100 point scale). 2. The level of life satisfaction was found to show the score of $19.57{\pm}3.39$ in 30 point scale(65.2 in 100 point scale). Characteristically, the highest score was found in male in both age groups younger than 19 and in 20s, but lowest score was found in the age group in 40s(p<0.001). In the level of life satisfaction, 29.6% responded as satisfactory and 11.9% responded as not satisfactory. 3. In reviewing the life satisfaction by the health related characteristics, 65.7% of whom responded as very healthy answered satisfactory in life, and the life satisfaction was significantly high in peoples who do not smoke. However, the level was significantly higher in alcohol drinker than no alcohol drinker. People who have enough sleep tended to satisfy in their life, and the life satisfaction level of whom have leisure turned out to show superiorly high satisfaction level. 4. As the variables affecting on the life satisfaction, sex, age, education level, marital status, health status, stress level, life satisfaction level, healthy life activities and depression level were found, and the influence of these variables was 19.6%. As the above results demonstrate, the life satisfaction of residents in regional community was proportional to health status and highly affected by daily health life. So, the more attentions have to be made on health management and the self effort should not be neglected. Especially, since stress, depression level and leisure life did have effects on life satisfaction, more attentions have to be made on stress solving and on the development of leisure life programs. For the goal, the governments, related private organizations and specialized workforces have to make integrated efforts along with the health improvement project in large perspectives.

Objectives: This study was conducted in order to improve the current understanding of rare earths(RE) and to provide supporting data for establishing occupational health policies by reviewing the toxicological data and issues caused by the use of RE compounds in various fields. Methods: To evaluate the potential toxicity of RE from the viewpoint of occupational health, we summarized extensive reviews of relevant articles in the toxicology(animals and cells), occupational health and safety, and epidemiologic literature. Results: Although occupational RE exposure occurs extensively from ore mining and refining to end users in various industrial applications, epidemiologic study has not been performed among workers up to now. Bioaccumulation and adverse effects of RE have also been mentioned in ore mining regions and nearby residences, but safety standards for each process are insufficient. Moreover, because new commercial recycling technology will soon be applied to various industries, regulation and policies are needed for preventing abuse of recycling. In the results of animal toxicity for a few REs(mostly cerium, lanthanum, and gadolinium), toxicities of liver, lung, blood, and the nervous system were identified due to oxidative stress, but study of long-term RE exposure is required. Understanding the dual effect for RE and discovery of biomarkers pose a scientific challenge in further mechanism studies. Conclusions: In the future, additional hazard evaluation based on animal experiments is required, alongside continuous research for developing analytical methods and discovering biomarkers. Finally, RE occupational health and safety management needs to be integrated into the sustainable use of these materials.
