Purpose: The National Health Insurance Service-National Sample Cohort and medical checkup data from 2002 to 2013 were used to evaluate the association between periodontal surgery for the treatment of periodontitis (PSTP) and vasculogenic erectile dysfunction (VED). Methods: Bivariate and multivariate logistic regression analyses were applied to a longitudinal retrospective database to assess the association between PSTP and VED while adjusting for the potential confounding effects of sociodemographic factors (age, household income, insurance status, health status, residence area, and smoking status) and comorbidities (diabetes mellitus, angina pectoris, cerebral infarction, and myocardial infarction). Results: Among the 7,148 PSTP within the 268,296 recruited subjects, the overall prevalence of VED in PSTP was 1.43% (n=102). The bivariate analysis showed that VED was significantly related to PSTP (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.38-2.06; P<0.001), and this was confirmed in the multivariate analysis after adjusting for sociodemographic factors and comorbidities (OR, 1.29; 95% CI, 1.06-1.58; P=0.002). Conclusions: Subjects with a history of periodontal flap surgery had a significantly higher risk of VED, after adjusting for potential confounding factors. Further studies are required to identify the key mechanisms underlying the association between severe periodontal disease and VED.

Objectives: This study aimed to examined the socioeconomic disparities in oral health related behaviors and to assess if those behaviors eliminate socioeconomic disparities in oral health in a nationally representative sample of adults aged 30-64. Methods: Data are from the Korea Third National Health and Nutrition Examination Survey (2005). Behaviors were indicated by smoking, over intake of daily calories from carbohydrate, perceived stress, frequency of daily tooth brushing, use of oral hygiene goods, insufficient oral treatment. Oral health outcomes were self-reported dental caries and periodontitis during the last 12 months and perceived oral health. Education, household income, and employed status indicated socioeconomic position. Sex, age, residential area, marital status were adjusted for in the logistic regression analysis. Logistic regression analysis was used to assess socioeconomic disparities in behaviors. Logistic regression model adjusting and not adjusting for behaviors were compared to assess the change in socioeconomic disparities in oral health. Results: Clear socioeconomic disparities in all behaviors were showed. After adjusting for behaviors, the association between oral health and socioeconomic indicators attenuated but did not disappear. For example, the odd ratios of reporting poorer oral health for persons in no education or elementary school education and middle school education groups, compared with college or higher education group, were 1.77 (95% CI: 1.36-2.29) and 1.56 (1.19-1.97), respectively. After adjusting for all indicators of behaviors, these odds ratios attenuated to 1.54 (1.17-2.03) and 1.48 (1.15-1.91) for those groups, respectively. Conclusion: These findings suggest that the presence of more complex determinants of socioeconomic disparities in oral health should be considered with developing preventive policies for those disparities.

In this paper, we propose a method for compliance control of a SCARA type 2-freedom direct drive(DD) manipulator. Each joint of the manipulator is driven by a travelling ultrasonic motor(USM). The travelling USM has good some characteristics over conventional servo motors such as compact size, light weight, silent motion, high torque and high speed response. By controlling the elasticity and viscosity of robot joints, a robot can work in compliance with external environment. we control the elastic coefficient and the viscous coefficient of joint by adjusting the phase difference of the motor power. And we contemplate transient response of USM with adjusting the elastic coefficient and the viscous coefficient. To use the result, we can control the robot to reach its goal with compliance motion. It remains for further research to develop the impedance control of USM.

The challenge of accurately predicting eyelid height after blepharoptosis surgery is well-known problem even in complete hands. From May, 1988 to December, 2004, authors reviewed 182 cases(240 eyes) of blepharoptosis corrected by frontalis muscle transfer or levator resection and had experienced 10 cases(15 eyelids) of early reoperation around 1 week. The period from initial operation to reoperation are between six to eight days and mean period is seven days. Initial operative procedures were frontalis muscle transfer in 3 cases(4 eyelids) and levator resection in 7 cases(11 eyelids). Follow up period ranged from 6 months to 16 years. Early adjusting surgery was performed in accordance with the preoperative and postoperative degree of ptosis of patient and considering previous operative technique. The results are evaluated according to the criteria of an ideal correction by Souther and Jordan. Seven patients have good or satisfactory results(less than 1 mm asymmetry, good in 5 cases and satisfactory in 2 cases). Three patients(5 eyelids) recorded as poor results(more than 2 mm asymmetry). Even if early or late reoperation can be effective in correcting unsatisfactory results after correction of blepharoptosis, early reoperation is better than later reoperation because early reoperation can offer a reduction in time to final result, the ease with which it is performed, potential cost savings. The experience of surgeon is also important factor for the reatment of recurred blepharoptosis

BACKGROUND/OBJECTIVES: Sugar-sweetened beverages (SSBs) are regarded as modifiable risk factors for mental health in several populations. Although the consumption of SSBs is steadily increasing in Korea, there is scant evidence regarding the impact of SSB consumption on depression and suicidal ideation. The aim of this study was to investigate the association of SSB consumption with depression and suicidal ideation among adults in Korea. SUBJECTS/METHODS: We used the data for 5,465 participants (2,170 men and 3,295 women) aged ≥ 20 years from the 2014 and 2016 Korea National Health and Nutrition Examination Survey. The subjects were divided into four groups according to SSB consumption using a food frequency questionnaire. Logistic regression analyses were conducted to examine the association of SSB consumption with depression and suicidal ideation, adjusting for sociodemographic, health behavior, and dietary variables. RESULTS: Participants consuming ≥ 1 SSB/day had a significantly higher risk of depression (odds ratio [OR], 1.54; 95% confidence interval [CI], 1.08-2.18; P < 0.001) and suicidal ideation (OR, 2.20; 95% CI, 1.13-4.28; P < 0.001) compared with those in the non-SSB group after adjusting for potential confounding factors. CONCLUSIONS: Our results suggest that SSB consumption is positively associated with depression and suicidal ideation in Korean adults.

Both angiography and interventional procedures accompanied by angiography provide many diagnostic and therapeutic benefits to patients and are rapidly increasing. However, unlike general radiography or computed tomography using the same X-ray, the amount of radiation is quite high, but the dose range can vary considerably for each patient and operator. The high sensitivity of the lens to radiation during cerebral angiography and neurointervention is already well known, and although there are many related studies, it is insufficient to easily reduce radiation in diagnosis and treatment. In this situation, in particular, by adding three-dimensional rotational angiography (3D-RA) to the existing two-dimensional (2D) angiography, it is now possible to make an accurate diagnosis. However, since this 3D-RA acquires images through projection of more radiation than before, the exposure dose of the lens may be higher. Therefore, we tried to analyze whether the radiation dose of the lens can be reduced by moving the lens out of the field range by adjusting the table height and magnification ratio during the examination using 3D-RA. The surface dose was measured using a rando phantom and a radiophotoluminescent glass dosimeter (PLD) and the radiation dose was compared by adjusting the table height and magnification ratio based on the central point. As a result, it was found that the radiation dose of the lens decreased as the table height increased from the central point, that is, as the lens was out of the field of view. In conclusion, in 3D-RA, moving the table position of about 2 cm in height will make a significant contribution to the dose reduction of the lens, and it was confirmed that adjusting the magnification ratio can also reduce the surface dose of the lens.

BACKGROUND/OBJECTIVES: Although adherence to a higher diet quality may help prevent cognitive decline in older adults, literature for this in a Korean population is limited. Thus, the aim of this study was to examine the association between diet quality indices and the risk of mild cognitive impairment (MCI) in Korean older adults. SUBJECTS/METHODS: This cross-sectional study included 806 community-dwelling people aged 60 yrs and over in Korea. Diet quality was assessed via the revised Recommended Food Score (RFS) and alternate Mediterranean Diet Score (aMDS). Cognitive function was measured using a Korean version of the Mini-Mental State Examination (MMSE-KC). Associations between diet quality indices and MMSE-KC score were assessed with a general linear model after adjusting for covariates. Logistic regression was used to determine the association between diet quality indices and the risk of MCI. RESULTS: The prevalence of MCI was 35.3%. There were no significant trends between MMSE-KC scores and RFS and aMDS after adjusting for age, gender, education, exercise, living status, social activity, and alcohol drinking. Among total subjects, RFS was inversely associated with the risk of MCI after adjusting for covariates (Q5 vs. Q1; odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28-0.83). Among total subjects and men, aMDS was inversely related to the risk of MCI after adjusting for covariates (Q5 vs. Q1; OR, 0.51; 95% CI, 0.29-0.89 for total subjects; Q5 vs. Q1; OR, 0.36; 95% CI, 0.15-0.83 for men). CONCLUSIONS: Our results demonstrate that high diet quality evaluated by RFS and aMDS is inversely associated with the risk of MCI. Thus, high quality diet may reduce or retard cognitive decline in the old population. Longitudinal studies are needed to determine the causal relationship between diet quality and the risk of MCI in the elderly.

Objectives: The purpose of this study was to investigate the differences in smoking rates according to the major occupational categories in South Korea. Methods: The study subjects were a weighted sample of 24,495 men and 26,121 women aged 25-64 from the 2003 Social Statistics Survey, which was conducted by the Korea National Statistical Office. Occupation was classified according to the Korean Standard Occupation Classification. We computed the age-standardized smoking rates according to gender and occupations after adjusting for the education level, marital status, and self-rated health. Results: For men, the smoking rate in elementary occupations was two times higher than that of clerks (OR=1.98, 95% CI=1.74-2.26). In general, a more prestigious job(professionals) correlated with lower smoking rates, and less prestigious jobs correlated with higher smoking rates, except for legislators, senior officials and managers. For women, smoking among service workers was 4.1 times higher than among clerical workers (OR=4.11, 95% CI=2.87-5.88). For women, their occupations, except elementary workers, and the unemployed, the retired and the armed forces, failed to show significant differences in smoking compared with the clerical workers. After adjusting for education, occupational differences in the smoking rate for men were attenuated in most occupations, except for legislators, professionals, and technicians. Further adjustment for marital status and self-rated health had a minimal effect on the occupational differences in the smoking rate for men. For women workers with service or elementary occupations, the ORs of smoking were attenuated with adjustment of the educational levels. However, the ORs of smoking were increased in workers with service, sales or elementary occupations, as well as for legislators, and the unemployed, the retired and the armed forces, after additionally adjusting for marital status. Conclusions: More prestigious jobs generally correlated with lower smoking rates in both sexes. The anti-tobacco policy should consider smoking rate differentials by occupations.
