Recent cross-sectional studies indicate that obesity is a risk factor for periodontal disease. This study was aimed to investigate whether the four-week weight control program including caloric restriction and exercise training could have an effect on periodontal health. Forty-one obese (body mass index [BMI] ${\geq}25.0$) and five overweight ($23.0{\leq}BMI<25.0$) students participated in the weight control program. Anthropometric data and oral examination data were collected at the baseline and at the 27th day. BMI, waist hip ratio (WHR), and percent of body fat (PBF) of the subjects decreased significantly, but gingival index, sites with bleeding on probing (BOP), and sites with shallow pocket depth didn't show the significant changes in paired t-test. There was no difference in the outcomes according to smoking, drinking alcohol, and sex. Nevertheless, PBF and sites with BOP (r=0.777) and WHR and sites with shallow pocket depth (r=0.444) showed positive correlations. PBF accounted for 58.9% of the variance in sites of BOP in regression analysis. We suggested that obesity might relate with periodontal health, although it was not clear whether weight control could influence on periodontal health directly.

The purpose of this study was to investigate effects of academic stress levels on life-style behaviors and mental health among the junior high school students in Korea. A convenient sample drawn from the 842 students from 8 junior high schools in Seoul and Kyunggi-Do area was investigated with a survey instrument. Female students showed higher academic stress levels compared to male students, especially in terms of the stress related to teachers, class time, and peer relationships. For the male students, higher stress levels were related to the higher risk factors of smoking, drinking and inhaling drug abuse. Students who had higher academic stress levels spent more time in using computer and playing digital games compared to those who had lower academic stress. In addition, higher academic stress levels were significantly related to risk of mental health, especially depression. These results suggest the urgent needs of preventive or educational program to support students with academic stress resolve in healthy manners such as playing sports or music or club activities.

This study has analyzed the factors related to everyday stress, professional stress, and professional satisfaction experienced while performing administrative duties in unit of school, concerning administrative education government officials. The study period was set from March 10 to March 30, 2013, and the subjects of study was set as 122 employees of Cheongwon-gun, Cheongju-si, Chungcheongbuk-do, working as administrative education government officials. The spsswin18.0 program was used for data analysis, and the t-test, and frequency analysis and credibility were also analyzed. The positive analysis was verified at a significant level of 5%. The results of the analysis displayed regarding the Professional Satisfaction pursuant to demographic Characteristic, the difference of Professional Satisfaction between positions was meaningful. However, the differences between sex, age, religion, educational background, marital status, school level, school scale, career, drinking, smoking were not analyzed as meaningful at a significant level of 5%. With regard to Sub-factors of Professional Satisfaction for Demographic Characteristic, the factors in the part of human resource management, human relation, and job capacity were analyzed as meaningful but organizational atmosphere was analyzed as not meaningful at a significant level of 5%. Also with regard to the stress on Quantitative Role among Sub-factors of Professional Stress by Demographic Characteristic, the difference between age, school level, position, career, smoking was meaningful. With regard to career development, the difference between smoking was meaningful. With regard to the stress on role conflict and ambiguity, the difference for demographic characteristic was analyzed as not meaningful at a significant level of 5%. This study implies that the social environmental consideration is required for administrative education government officials, and it is regarded that consideration is required sequentially to developing job capacity, human relation, organizational atmosphere, rather than to human resource management.

Excessive alcohol consumption is one of the leading causes of many neurological diseases, such as dementia and Alzheimer's disease, and many efforts are under way to solve them. Red ginseng is known to enhance neuronal survival, inhibit apoptosis, and promote nerve regeneration of nerve cells. This study examined whether Rg3-enriched Korean red ginseng extract (KRG) inhibits the apoptosis of PC12 cells caused by alcohol-induced neurotoxicity and how KRG regulates several factors related to the caspase mediated pathway. In this way, the cell survival rate and apoptosis rate of PC12 cells were measured using an EZ-Cytox cell viability assay kit and flow cytometry, respectively. The expression of the apoptosis-related proteins (Bcl-2, Bid, Bax and caspase-3) were analyzed by western blotting, and the significance of the measured results was confirmed using the ANOVA method. As a result, KRG increased the expression of Bcl-2; inhibited the expression of Bid, Bax, and caspase-3; and inhibited the apoptosis of alcohol-induced PC12 cells. These results mean that the KRG-induced increase in Bcl-2 expression and down-regulation of Bid and Bax expression down-regulate caspase-3 expression, which in turn inhibits the mitochondrial apoptotic pathways. This study suggests that KRG is worth developing as a neuroprotective agent candidate.

A case-control study was conducted to investigate the effect of low-level blood lead on the blood pressure. The plasma renin activity(PRA) was measured also to investigate one of the possible mechanisms by which lead nay play a role to influence on the blood pressure. Seventy-two hypertensive and sixty -nine control study subjects were selected from the workers who had no history of b-related lead exposure, in Ulsan city and it's vicinity, Korea. In addition to measuring blood lead levels and PRA, body mass index(BMI), hematocrit, serum sodium, potassium, creatinine, ionized calcium, and cholesterol were measured. Also, the habits of smoking, alcohol drinking and family history of hypertension were checked. The blood lead level of the hypertensive group was $19.8{\pm}5.5{\mu}g/dl$, which was significantly higher than that of the control group, $12.5{\pm}4.7{\mu}g/dl$(p<0.01). On multiple logistic regression analysis, the odds ratio of blood lead level on the occurence of high blood pressure was 1.38, also statistically significant (p<0.01). There was no significant differences between the hypertensive and the control group in the PRA or In (PRA), but there was a marginally significant linear relationship between blood lead and PRA in the hypertensive group(p<0.1). In conclusion, blood lead level which has been known to be within normal limits may be one of the possible risk factors of hypertension and PRA alteration by lead may act as one of the mechanisms.

Correlation between occupational exposure levels to toluene and urinary hippuric acid (HA) concentrations were studied for 124 workers at 54 work places. The highest indoor toluene concentration measured at printing process was 81.116 ppm, and their geometric average concentration was as high as 12.304 ppm. The geometric average concentration of hippuric acid in urine samples from workers who are exposed to toluene was 0.714 g/g creatinine. This is almost five times higher than the average HA concentration from non-exposure workers. Printing workers showed the average HA concentration of 1.145 g/g creatinine from their urine samples. It is the highest concentration among the workers exposed to toluene. The correlation coefficient between HA concentrations in urine and indoor toluene concentration at work places was relatively high as r=0.624 (P<0.01). But the correlations of HA with sex, smoking, drinking, age and employment history was relatively low. We can express the regression equation for the urinary HA concentration which is Y = 0.037X + 0.562 as exposure toluene concentration is X. The urinary HA concentrations showed significantly increase depend on indoor toluene concentration at work place.

This study aimed to present cosmetic countermeasures for preventing fast aging process in the middle age and accepting healthy aging both physically and mentally by investigating the perception of aging according to the health condition, lifestyle and psychological condition targeting mid-aged women in 40s to 50s residing in Seoul and Gyeonggi-do Province. The data collection period was from July 25 to Sept 1, 2015. The data was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. It was shown that as the age was higher, the menopause ratio was higher, drinking, exercise volume and hours of sleep were reduced and the stress and psychological pressure were higher. According to the menopausal status, the status of facial aging showed a significant difference (${\chi}^2=39.692^{***}$, p<.001), and it also showed a difference according to the status of leisure (hobby) activity (${\chi}^2=22.470^{***}$, p<.01). Also, as higher the age and closer to the menopause in items including the progress of aging, anxiety about aging and improvement efforts, more negative perception was shown, indicating that it is necessary to prepare cosmetic countermeasures for mid-aged women in like a second puberty 40s to 50s although aging and menopause around 50s are very natural. If a beauty alternative is provided, it will help them to have a successful retirement.
