Objective : To develop a boner understanding of the relationship between weight status and the prevalence of obesity related diseases in the Korean population. Methods : The 1998 Korean National Health and Nutrition Survey was used and 10,880 persons who had previously taken health examinations were selected for study. The Korean Society for the Study of Obesity's classification of weight status was used. Hypertension, diabetes mellitus, dyslipidemia, osteoarthritis, chronic heart disease, stroke were included as obesity related disease. A logistic regression model was developed to estimate the prevalence odds ratio by obesity class adjusted for demographic and socioeconomic factors and we converted the odds ratio to a prevalence ratio using the base line prevalence of disease to aid in the interpretation of the ratios. Results : The prevalence of obesity was 26.3% based on the KSSO classification $(BMI\geq25)$. A graded increase in the prevalence ratio was observed with increasing severity of overweight and obesity for all health outcomes with the exception of chronic heart disease in men and stroke in both men and women. With normal weight individuals as the reference, for men who were younger than 50 years, the prevalence ratios were highest for hypertension BMI<23-25: 1.70(95% CI=1.41-2.05), 25$BMI\geq30$: 4.83(95% CI=3.70-5.84). The prevalence ratios for dyslipidemia were as high as hypertension, but were lower than hypertension for diabetes mellitus and osteoarthritis. Prevalence ratios generally were greater in younger adults. The prevalence of having 2 or more obesity related diseases increased with weight status category, except in people who were older than 50 years. Conclusions : Based on results, obesity is an increasingly important health problem in Korea and the disease burden increases according to weight status. For Korean adults, the strongest relationship was seen between weight status and hypertension and dyslipidemia. In older people the impact of excess weight and obesity is stronger than that seen in younger people. Increased efforts in the study of obesity and prevention and treatment of obesity and obesity related disease are required.

Objectives: Plasma lipid profiles and Apolipoprotein E (ApoE) are established risk factors for cardiovascular disease (CVD). The knowledge of lipid profile may estimate the potential victims of cardiovascular disease before its initiation and progression and offers the opportunity for primary prevention. The most common ApoE polymorphism has been found to influence plasma lipid concentrations and its correlation with CVD has been extensively investigated in the last decade. Methods: The ApoE polymorphism and its influence on plasma lipid were investigated in healthy woman workers. The information on confounding factors was obtained through a self-administered questionnaire and ApoE polymorphism was investigated using PCR. Results: The relative frequencies of alleles E2, E3 and E4 for the study population (n = 305) were 0.127, 0.750 and 0.121, respectively. ApoE polymorphism was associated with variations in plasma HDL-cholesterol lipid profile. In order to estimate the independent effects of alleles E2 and E4, as compared with E3, on lipid profile, multiple regression was performed after adjustment for confounding variables such as age, BMI, blood pressure, education status, insulin, fasting glucose, HOMA-IR, menopause. ApoE2 had a negative association with HDL cholesterol and ApoE4 had a positive association with LDL cholesterol. Conclusions: This study identified that the ApoE and CVD risk factors contribute to the lipid profiles, similar to other studies. The analysis including dietary intake and other gene in further studies may help to identify clear effects on lipid profiles as risk factor for CVD.

Purpose: The purpose of this study was to develop a new fall-prevention exercise intervention for the community-dwelling elderly and to examine the effects of program. Methods: A total of 7 older adults were participated in a 10-week fall-prevention exercise intervention (1 day per a week in community centers, 2 days per a week in a home). The exercise program consisted of warming-up, extension exercises, muscle strength exercises, balance exercises, and finishing exercise. Data were collected before the exercise and after 10 weeks of exercise. In this study, muscle strength of lower limbs was measured by 10 times of standing up and sitting on a chair. Static balance was measured by one-leg standing, and dynamic balance was measured by 6 meter walking. Results: After a 10-week exercise program, muscle strength of lower limbs (t=4.18, p<.05), statical balance were significantly improved (left leg, t=-3.11, p<.05; right leg, t=-4.56, p<.05). Seven of 11 items measuring fear of falls were significantly decreased (p<.05), and dynamic balance tended to be improved (p=.117). Conclusion: This result suggests that evidence-based, fall-prevention exercise program can improve muscle strength, static and dynamic balance, and fear of falling in the community living elderly.

Objectives: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. Methods: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants' frailty. Results: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. Conclusions: More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.

Objectives: The aim of this study was to observe the changes of women's postpartum symptoms, the quality of life and depression scale over the first six weeks after childbirth. Methods: Twenty seven mothers who received Korean medical treatment in the outpatient department treatment (from September 27th, 2017 to January 5th, 2018) were evaluated for Verbal numerical rating scale (VNRS), edema index, EuroQol Visual Analogue Scale (EQ-VAS), and Edinburgh Postnatal Depression Scale (EPDS). Results: There were 17 high risk participants (63.0%) and 10 normal participants (37.0%). The VNRS of edema is the highest in the first week, and the VNRS of joint pain is the highest from the second week to the sixth week in all patients. The Extra Cellular Water/Total Body Water (ECW/TBW) of high risk group significantly decreased from $0.403{\pm}0.011$ to $0.387{\pm}0.006$(p<0.05) in the first 2 weeks. The ECW/TBW of normal group significantly decreased from $0.393{\pm}0.070$ to $0.383{\pm}0.011$ (p<0.05) in the first 2 weeks. The EQ-VAS of high risk group increased from $64.12{\pm}13.941$ to $69.35{\pm}18.155$ (p<0.05) in the first 2 weeks. But this difference was not significant statistically (p=0.234). The EQ-VAS of normal group significantly increased from $62.50{\pm}21.763$ to $74.00{\pm}9.661$ (p<0.05) in the first 2 weeks. The difference of EPDS was not statistically significant between the first week and the sixth week in every participants. Conclusions: VNRS was the highest in edema in the first week, joint pain was the highest from the second week to six week. The edema index of high risk groups was higher than that of the normal group in the first week (p<0.05). The EQ-VAS of normal group significantly increased (p<0.05) in the first 2 weeks but high risk group didn't. In the EPDS, the ratio of nine or more points of high risk group was more than twice than normal group in the first 2 weeks.

Objectives : The Glycyrrhiza new varieties, WONGAM and SINWONGAM, were developed through interspecific cross between Glycyrrhiza glabra and Glycyrrhiza uralensis by the National Institute of Horticultural and Herbal Science, Rural Development Administration in Korea. This in vitro study was undertaken to compare the antioxidant and cytotoxic effects between Glycyrrhiza new varieties (WONGAM and SINWONGAM) and official compendia (Glycyrrhiza glabra and Glycyrrhiza uralensis). Methods : Antioxidant activity was determined by DPPH (1,1-diphenyl-2-picrylhy drazyl), ABTS (2,2-azino-bis (3-rthylbenz-thiazoline-6-sulfonic acid)) diammonium salt, Nitrite radical scavenging assay, and Reducing Power assay. Cytotoxicity was determined by MTT assay and cell morphology was observed by an inverted microscope. Results : The DPPH, ABTS, Nitrite radical scavenging activities and reducing power of Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM were evaluated at different concentrations (0, 10, 50, 100, 500, 1000 ㎍/㎖). Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM showed similar dose-dependent increase in antioxidant activities. The cytotoxic effects with increasing doses of Glycyrrhiza new varieties and official compendia did not differ in HCT116, HT29, A549, MDA-MB231, PC3, ACHN, and HeLa cells. However, significant difference in cytotoxicity were observed in AGS, MCF7 and Hep3B cells by Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM. Conclusions : These results showed that Glycyrrhiza new varieties and official compendia acts as a potent antioxidant. Also, the finding that equivalent cytotoxic potency was observed in a cell dependent manner. Our study suggests that Glycyrrhiza new varieties may offer a wide-variety of health benefits.

According to a survey on the frequency of access to medical ads by the Korea Press Foundation in 2017, the most commonly exposed ads among adult men and women are advertising about beauty, plasticity and obesity. As of 2011, South Korea had the largest number of cosmetic surgeries in the world, with 131 cosmetic surgeries per 10,000 people. As a result, as many as 1,414 plastic surgery clinics are operating in South Korea, and the number is also on the rise. Although there are various standards for evaluating people's appearance, the desire to pursue a better look is growing day by day. Then, one might wonder what factors influence consumers' choices among the numerous advertisements for plastic surgery clinics. Based on these questions, this study identified the examples of plastic surgery advertisements, analyzed their type, and identified the types of advertisements with the high visual appeal of the advertising consumer through eye tracking experiment. In total, seven eye-tracking tests of plastic surgery social media advertisements were conducted on 10 subjects. The results showed that the commercial model was the biggest factor that caught the attraction and attention of the ad recipient first and that the most focused and long-standing factor was the treatment contents. Therefore, it is important to select proper commercial models for hospital and clinic contents and to specify factual treatment contents when producing social media advertisements for plastic surgeons. We hope these findings will help create online advertising for plastic surgery clinics effectively.

Objective : This study was conducted to determine the emotional labor of occupational therapists and the level of their feelings of depression and to examine the impact of their emotional labor on their depressive mood. Methods : Subjects of this study were clinical occupational therapists working at hospitals and clinics in Seoul and Gyeonggi regions. The factors of emotional labor were set as independent variables, the general characteristic variable and job characteristic variable which showed significant results in the chi-square test was set as the adjusted variable and whether the depression happens or not was set as the dependent variable, after which a multivariate logistic regression analysis was conducted. Results : Components of emotional labor, including frequency of emotional display(OR 1.699, 95% CI 1.202-2.401), attentiveness to required display rules(OR 1.436, 95% CI 1.070-1.982), and emotional dissonance(OR 1.866, 95% CI 1.336-2.607) all had a significant effect on depression. The possibility of depression was significantly higher in women than men(OR 5.736, 95% CI 1.746-18.846), those working for more than 8 hours per day than less than 8 hours per day(OR 8.609, 95% CI 2.306-32.137), and those working with children than those working with adults(OR 4.249, 95% CI 1.668-10.824). Conclusion : This study revealed that the emotional labor that occupational therapists are exposed to while interacting with patients and their caregivers exerts an influence on their feelings of depression. This suggests the need for developing various preventive intervention programs designed to alleviate the depressive symptoms of occupational therapists and formulating appropriate policies.
