Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.
Background: It is well known that the prevalence of obesity in Korea is increasing over time, however it is not known how the trends among occupational groups and sex differ in such increasing trends. This study was designed to provide recent trends of obesity among workers in Korea and to identify whether there were differences among occupational groups. Methods: We used data from the Korean National Health and Nutrition Examination Survey, Phases I to VI (19982015), to analyze trends in the prevalence of obesity in adult Korean workers. Obesity was defined as a body mass index of 25 kg/㎡ or higher. Occupations were classified into 3 groups: (a) nonmanual workers, (b) service/sales workers, and (c) manual workers. Results: During the period of the Korean National Health and Nutrition Examination Survey Phases I to VI, the prevalence of obesity in male workers increased in all occupations (31.1% to 39.5% in manual workers, 32.3% to 38.2% in service/sales workers, and 25.3% to 39.7% in manual workers). However, female workers did not show any particular tendency toward obesity, except for a significant decrease in the prevalence rate in service/sales workers (30.8% to 23.9%, p for trend = 0.0048). Conclusion: The trends of obesity prevalence by sex and occupation were different. For male manual workers, the prevalence rate increased steadily during the data period, while it decreased steadily in female sales/service workers.
Blood serum from 30 pregnant cows, 6 non-Pregnant cows (one month after delivery), 6 sterile cows (ovarian cyst), and 6 heifers (16 months old) were analyzed for total vitamin E concentration by the ferric chloride-bipyridyl reaction. The pregnant group was determined periodically throughout pregnancy. The results obtained were as follows: 1. The mean value of serum vitamin E level in pregnant group was $0.651{\pm}0.068(SE)mg/100ml$, in non-pregnant group $0.647{\pm}0.119(SE)mg/100ml$, in sterile group $0.488{\pm}0.053(SE)mg/100ml$, and in heifer group $0.083{\pm}0.016(SE)mg/100ml$. Samples below 0.19mg/100ml were net observed and most of the pregnants (83.3%) showed the values of 0.40 to 0.99mg/100ml during pregnancy 2. The difference of vitamin E level between pregnant group and non-pregnant group was net significant, but these trio groups showed a significantly higher value than that of sterile group. On the other hand, in heifer group was recognized significantly lower value compared with adult groups. 3. The change of serum vitamin E level in pregnant group revealed the tendency of decrease as gestation progresses and significantly dropped at the eighth month, thereafter, the value was rose slightly at the tenth month of gestation but no differences were observed. The coefficient of correlation between months and serum vitamin E levels during pregnancy was r=-0.956(p<0.01), and a regression equation was Y (serum vitamin E levels, mg/100ml)=1.034-0.063x(month).
This study focused on the disintegration and reconstruction of the family/kinship structure among the rural families of Korea. For this study, detailed data about the value related to the family/kinship, the family relationship, The attitude of divorce and remarriage, the social network, and the family/kin rites are gathered A total 593 subjects completed structured questionnaires. Major conclusion of the study are as follows : First, most of the rural respondents are found to support familism and boy preference slightly, and not to agree the reward of child value. So, their attitudes toward traditional values are changing slowly than urban residents. Second, the rural respondents shared the common perceptions that spousal and parent-child relationships has been changed toward the direction that the positions of wives and children are respected and the their influences are increased in the past 10 years. In addition, generational differences in the perceptions of relationship change and appropriate roles of wives and husbands are discovered. However, sex differences previously revealed in Seoul study were not found in the case of rural respondents. Third, generally, there are both remaining and changing aspects of conservative attitude toward divorce and remarriage, the level of change is different according to age and sex. And the difference by age is stronger than by sex. Fourth, the social networks of the respondents is characterized by two distinct trends, namely, strong parent-adult child ties and the close relationships between neighbors. fifthly, in the family/kin rites, traditional aspects coexist with changing aspects under the influence of industrialization and westernization. But the aspects of attitudes toward rites, it is showed the non-traditional tendency. Respondents who support westernization and socialization of family rites are young, highly eamed, and Christian.
Maxillary deficiency, anterior cross bite, constriction of maxillary arch, malaligned teeth are frequently observed in patients with cleft lip and palate. Surgery and orthodontics, combined intervention are needed to correct maxillary deficiency. Distraction osteogenesis that currently used has many advantages like less relapse tendency, more advancement of maxilla, capable in growing patients. In case 1, 18 years old girl with BCLP had severe midfacial deficiency and multiple missing of teeth. LeFort I osteotomy, followed by maxillary distraction osteogenesis utilizing rigid external distraction device(RED) system, was performed. After a 6-day latency period, distraction proceeded at a rate of 1mm per day (at 1st week, 1.5mm/day). Total advancement was 19mm. The RED device left in place for the additional 4 weeks for consolidation. After the RED device was removed, face mask was applied with elastic traction for 5 weeks. After achieving acceptable facial appearance and occlusion, orthodontic appliance was removed. The results after 4 years follow-up was sustained pretty well without aggravation of velopharyngeal function. In case 2, 22 years old man with UCLP had severe midfacial deficiency and palatally erupted upper 2nd premolars due to arch length discrepancy, but the anterior segment of maxillary did not show constriction and crowding. patient had no arch width discrepancy, crowding was concentrated on premolar region. Segmental LeFort I osteotomy was performed. After a 6 - day latency period, using internal distraction device, distraction proceeded at a 0.5mm per day(at 1st week, 0.75 - 1 mm/day). Total advancement was 15mm. After internal distraction device was removed, face mask was applied with elastic traction for 4 weeks. After surgical-orthodontic treatment, facial appearance and occlusion was improved pretty good, and after 46 months follow-up the result was retained well.

STATEMENT OF PROBLEM. A few of studies which compared and continuously measured the stability of various surface treated implants in the same individual had been performed. PURPOSE. We aim to find the clinical significance of surface treatments by observing the differences in the stabilization stages of implant stability. MATERIAL AND METHODS. Eight different surface topographies of dental implants were especially designed for the present study. Machined surface implants were used as a control group. 4 nano-treated surface implants(20 nm $TiO_2$ coating surface, heat-treated 80 nm $TiO_2$ coating surface, CaP coating surface, heat treated CaP coating surface) and 3 micro-treated surface implants [resorbable blast media(RBM) surface, sandblast and acid-etched(SAE) surface, anodized RBM surface] were used as experiment groups. All 24 implants were placed in 3 adult dogs. $Periotest^{(R)}$ & ISQ values measured for 8 weeks and all animals were sacrificed at 8 weeks after surgery. Then the histological analyses were done. RESULTS. In PTV, all implants were stabilized except 1 failed implants. In ISQ values, The lowest stability was observed at different times for each individual. The ISQ values were showed increased tendency after 5 weeks in every groups. After 4 to 5 weeks, the values were stabilized. There was no statistical correlation between the ISQ values and PTV. In the histological findings, the bone formation was observed to be adequate in general and no differences among the 8 surface treated implants. CONCLUSIONS. In this study, the difference in the stability of the implants was determined not by the differences in the surface treatment but by the individual specificity.
Renal dysfunction is a common complication of open-heart surgery: a form of controlled hemorrhagic shock, and successful perioperative management of renal dysfunction depends on recognition of the risk factors and optimal management of factors influencing renal function, including cardiopulmonary bypass, and early detection of renal failure. Changes in renal functional parameters including Ccr, Cosm, CH2O, FENa, and RFI were observed prospectively in forty five patients operated on at Dept. of Thoracic and Cardiovascular Surgery, S.N.U.H., from April to June, 1985. They were 23 males and 22 females with 35 acquired and 10 congenital heart diseases and the mean age and body surface area of them were 38.010.3 years [22-63] and 1.5518 M2[1.151.92] respectively. Followings are the conclusion. 1. The Ccr, representative of renal function, is significantly improved from 90.231.3 ml/min/M2 preoperatively to 101.536.4 ml/min/M2 postoperative and day [P<0.05], and all patients were classified as postoperative renal functional class I of Abel, which representing adequate renal protection during our cardiopulmonary bypass. 2. The Cosm is significantly elevated at immediate postperfusion time and remained high at postoperative one day representing osmotic diuresis at that time, but CH2O shows no significant changes at immediate postperfusion period and is decreased significantly at postoperative one day, representing recovery of renal concentrating ability at that time with decreasing urine flow. 3. The absolute value and changing tendency in FENa and RFI during perioperative period shows no diagnostic reliability on these parameters, but those of CH2O appear to reveal future renal function more accurately than Ccr 4. The depth of hypothermia may be protective upon renal function against the ill effects of prolonged nonpulsatile cardiopulmonary bypass. 5. The depth of the hypothermia, pump time of more than 150 minutes, poor cardiac function, and intraoperative events such as embolism appear to be related with immediate postperfusion renal function. 6. Hemoglobinuria and hemolysis, poor preoperative renal function, history of cardiac surgery, and massive transfusion associated with bleeding appear not to be related with renal dysfunction.
The purpose of this study was to investigate several aspects of eating out behavior especially in relation to Korean food. Self-administered questionnairs were completed by 700 adults living Seoul and Kyunggi-do area from June to July 1994. The results were as follows: 1. The 68.4% of subjects ate outside home either frequently or occasionally. Lunch-eat-out was the most frequent and breakfast-eat-out, the least. Male subjects, adults under the age of 50, and students ate out more frequently. 2. The 70.3% of subjects spent less than 5000 won for the expense of eating out. Those under the age of 25 and students considered reasonable the expenditure of less than 3000 won for lunch and less than 5000 won for supper. But older adults and workers and housewives prefered $3000{\sim}5000$ won for lunch and $5000{\sim}15000$ won for supper. 3. Nayngmyun, bibimbap, jajangmyun, pizza, Broiled galbi, and pork cutlet were favorite eat-out dishes. Among Korean foods, bibimbap, Broiled galbi, nayngmyun, bulgogi and galbitang were frequently selected menues. While Korean dishes had a tendency to be selected as a first choice, noodle type dishes and western style fast food were prefered as a second and third choices. 4. Korean food restaurants received highest score in the food taste and familiarity evaluations. They also received good grade in such points as the nutritive value of food, amount of serving portion and the variety of menu. But as for the sanitation and food price, Korean restaurant scored the lower mark in comparison to noodle restaurant and fast food restaurant.
This study sought to identify the types of fashion brands preferred by tourists based on the shopping values that they pursue through purchases at tourist destinations and to verify the effects of these values on their satisfaction. To obtain a representative sample of South Korea's tourist shoppers, a survey was conducted among 300 subjects involving adult men and women in their twenties to sixties. Structural equation modeling analyses were performed on the collected data using SPSS and AMOS. The effects of tourist shopping values on brand attitudes were verified by dividing tourist shopping values into social, epistemic, and functional values and dividing brand attitudes into attitudes toward fashion global and local brands. Additionally, this work intended to ascertain the moderating effect of cosmopolitanism on tourist shopping behaviors. The analysis results reveal that a high level of epistemic value as perceived by tourists during shopping resulted in a corresponding high level of preference for local fashion brands. Furthermore, a high level of social value as perceived by tourists led to a high level of preference toward global fashion brands. Contrastingly, functional value influenced both local and global brands. As a result of the moderating effect, in the group with high cosmopolitanism tendency, the effect of epistemic value was not significant, but the low group significantly affected brand attitude based on the social and epistemic value. Given its academic and practical implications, the present study is likely to broaden the understanding of tourist shopping and facilitate future research on that phenomenon.

Background: Pembrolizumab, an anti-cancer drug, is known to increase the activity of the immune system, leading to side effects called immune-related adverse events (irAE), including type 1 diabetes. This study analyzed the correlation between blood glucose level and pembrolizumab administration and investigated the covariates that affect those changes in cancer treatment. Methods: The information of 133 adult cancer patients was obtained from the electronic medical record (EMR) to identify the changes in random blood glucose (RBG) levels during the pembrolizumab treatment. Subjects were classified into subgroups according to their baseline RBG level, history of diabetes, and the use of steroids, and linear regression analysis was conducted. In addition, a secondary analysis was performed within the group of subjects having a strong correlation to glycemic change, which was based on the Pearson correlation coefficient being less than -0.7 or greater than +0.7. Univariate and multivariate logistic regressions were conducted to identify the risk factors to glycemic increase. Results: The RBG level tended to descend without significant differences in total patients during the administration period of pembrolizumab. Despite the insignificance, the logistic regression analysis presents that the odds ratios of baseline RBG less than 130 mg/dL, prophylactic steroid use, and higher dose of pembrolizumab per cycle (mg/kg/cycle) were greater than 1. Conclusions: Prophylactic administration of steroids and a higher dose of pembrolizumab per cycle may increase the blood glucose level as irAE in cancer patients with a strong tendency to glycemic change.
