Purpose: The aim of this study was to evaluate the clinical outcomes of periodontal granulation tissue preservation (PGTP) in access flap periodontal surgery. Methods: Twenty patients (stage III-IV periodontitis) with 42 deep periodontal pockets that did not resolve after non-surgical treatment were consecutively recruited. Access flap periodontal surgery was modified using PGTP. The clinical periodontal parameters were evaluated at 9 months. The differences in the amount of granulation tissue width (GTw) preserved were evaluated and the influence of smoking was analyzed. Results: GTw >1 mm was observed in 97.6% of interproximal defects, and the granulation tissue extended above the bone peak in 71.4% of defects. At 9 months, probing pocket depth reduction (4.33±1.43 mm) and clinical attachment gain (CAG; 4.10±1.75 mm) were statistically significant (P<0.001). The residual probing depth was 3.2±0.89 mm. When GTw extended above the interproximal bone peak (i.e., the interproximal supra-alveolar granulation tissue thickness [iSUPRA-GT] was greater than 0 mm), a significant CAG was recorded in the supra-alveolar component (1.67±1.32 mm, P<0.001). Interproximal gingival recession (iGR) was significant (P<0.05) only in smokers, with a reduction in the interdental papillary tissue height of 0.93±0.76 mm. In non-smokers, there was no increase in the iGR when the iSUPRA-GT was >0 mm. The clinical results in smokers were significantly worse. Conclusions: PGTP was used to modify access flap periodontal surgery by preserving affected tissues with the potential for recovery. The results show that preserving periodontal granulation tissue is an effective and conservative procedure in the surgical treatment of periodontal disease.

The prevalence rate of thyroid dysfunction (hypothyroidism and hyperthyroidism) has increased within the Korean population and seems to be affected by iodine dietary habits. Some studies reported that the prevalence of thyroid dysfunction increase both in the area of iodine deficiency and excess. In this study, we tried to discover the difference in iodine intake, anthropometric measurements, and blood parameters between male subjects with or without subclinical thyroid dysfunction. A total of 5,249 subjects (Euthyroid: 4706, SubHypo: 454, SubHyper: 89) were used in this study. There were no significant differences in BMI, body fat, visceral fat, waist circumference, SBP, DBP, total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, fasting serum glucose, HbA1c, alcohol intake, however significant differences were noticed in both age and smoking status. Through a food frequency questionnaire (FFQ), iodine intake per day was estimated. The average iodine intake was similar (SubHypo $392.9{\pm}279.0{\mu}g$, Euthyroid $376.5{\pm}281.7{\mu}g$, SubHyper $357.3{\pm}253.8 {\mu}g$) among groups. The main source of iodine intake was eggs (52.8%, 54.2%, 52.4%) followed by milk (16.3%, 15.8%, 17.8%), then sea mustard & sea tangle (12.4%, 11.9%, 11.6%). The prevalence of subclinical hypothyroidism and subclinical hyperthyroidism was higher in subjects whose intake was higher than the recommended nutrient intake (RNI). These results suggest that the excess consumption of iodine intake may act as one of the risk factors regarding thyroid dysfunction in Korea. Therefore, an adequate amount of iodine intake is necessary in order to prevent subclinical thyroid dysfunction and clinical thyroid dysfunction.

This study aimed to compare energy nutrient intake, health related factors, physical characteristics, blood biochemical indices, prevalence of metabolic syndrome and odds ratio (OR) of metabolic syndrome based on dietary fat energy ratio. Subjects were 1,205 men aged 40~64 years. The average fat intake was 52.8 g. Subjects were divided into three groups (deficient, normal, excess) based on dietary fat energy ratio. The dietary fat energy rations of the three groups were 36.9%, 42.9% and 20.2%, respectively. Energy and protein intake were increased significantly with dietary fat energy ratio (p<0.001), whereas carbohydrate intake decreased (p<0.001). In health related factors, amount of smoking alone showed increase based on dietary fat energy ratio (p<0.001). In comparing physical characteristics, blood pressure and blood biochemical indices, excepting diastolic blood pressure, increased significantly based on dietary fat energy ratio (p<0.01~p<0.001). The rate that exceeded criteria in risk factors for metabolic syndrome was higher in the serum triglyceride (41.2%) and was lower in the waist circumference (22.2%). Prevalence of metabolic syndrome was 37.9%, and showed significant correlation to dietary fat energy ratio (p<0.05). The OR of metabolic syndrome was higher in deficient and excess group than in normal group, but it had no relationship between fat energy ratio and metabolic syndrome. The results of this study provide basic data to establish fat intake guidelines for prevention of metabolic syndrome in middle-aged men.

Purpose ： To describe epidemiological characteristics and related factors in school personnel with hypertension. Method ： 5,384 school personnel (2,638 males and 2,746 females) received physical examination at the Seoul School Health Center in 2002. blood pressure(BP) was classified by JNC 7th report. Normal BP is systolic BP <120 and diastolic BP<80, prehypertension BP is 120-139 or 80-89mmHg, stage 1 hypertension BP is 140-159 or 90-99, and stage 2 hypertension >=160 or >=100 mmHg. each group was evaluated by gender. We used multiple regression and logistic regression. Results ： Normotension was 20.13% in males and 48.65% in female, prehypertension 43.4% in males and 38.06% in females, stage 1 hypertension 26.38% in males and 10.99% in females, stage2 hypertension 9.59% in males and 3.2% in females. the older age group had higher distribution of stage 1 hypertension and stage 2 hypertension. The means and abnormal rates of BMI, blood sugar, total cholesterol, GOT, GPT, and GTP was higher when their blood pressure was higher. However, an alcohol habit among lifestyle factors had an inverse effect. Higher Bp was correlated to a higher BMI, FBS, and cholesterol-like dose response. In stage 1 hypertension, the related factors of hypertension for males were BMI, amount of cigarettes smoked, exercise, blood sugar, total cholesterol, and GTP. In stage 1 hypertension, age, BMI, exercise, blood sugar, total cholesterol were related factors in female. In stage 2 hypertension, age and smoking were related factors in male, and age, BMI, and cholesterol in female. Conclusions ： It is possible to intervene in all related factors of hypertension except age through life-style modification and appropriate medical management. Active health promotion is needed in School personnel.

The purpose of this study was to determine halitosis perception status of firefighters and identify the factors related to halitosis; for this purpose, a survey was conducted in 241 firefighters in Daejeon, obtaining the following results: First. The higher level of smoking and alcohol intake, the more likely to perceive halitosis; all of those with a general disease perceived halitosis; and the more stress, the more likely to perceive halitosis. Second, The respondents who brushed their teeth three times a day, who spent 1~2 minutes in brushing their teeth, who failed to wash their tongue, and who had never received oral health education were most likely to perceive halitosis. And third. such factors as age, the amount of tongue coating, and dry mouth affected halitosis perception status. Firefighters' halitosis perception is related to several factors. For this reason, emphasis is placed on the need to develop a program for helping firefighters prevent halitosis and remove oral symptoms and to give education for good oral health management.

The relationship between body weight and body image, an objective and subjective measure of body shape, respectively, has long been a recurrent concern in the area of medical sociology and health-related studies. This concern stems from the argument and findings in the literature indicating that the two are not necessarily likely to be strongly correlated due mostly to the fact that one's own idea or conception about his/her body shape could be pretty different from one's actual shape. This study tries to empirically address the two issues based on the analysis of a national sample survey data in Korea: to what extent body weight and body image are correlated with or deviated from each other, on the one hand, and what factors help to account for the relationship between the two, on the other. The latest(2010) national sample data of KGSS(Korean General Social Survey) is used to evaluate the issues. Results of data analysis demonstrate that body weight and image have a moderate amount of correlation, and that the correlation tends to vary to a large extent depending on a few major socio-demographic and socio-economic characteristics. Most important, the risk factor analysis attempted in this study could identify several salient risk factors, which include gender, age, chronic diseases, smoking, physical exercises, and medical checkup. To be precise, those who may be best characterized as particularly risky to weight gains are females, who are in their 20's, who have chronic diseases, non-smokers, who exercise regularly, and who conduct medical checkups on a regular basis. To extrapolate, the findings suggest that the most typically risky kinds of individuals in Korea are "young women who care very much for their health." The findings are interpreted and discussed with suggesting a recommendation for further studies.

This study examined the tongue coating index and halitosis to determine the association with the oral care behavior and variation in halitosis according to the tongue coating index, dental calculus, and the oral environment before and after scaling among 130 participants in scaling practices of the Department of Dental Hygiene at K University in Daejeon. The subjects were asked to participate in a survey, in an oral examination for the tongue coating index, dental plaque, and dental calculus status, and in halitosis measurement. The tongue coating most significantly affected halitosis and the tongue coating index was strongly correlated with smoking and tongue washing. More frequent toothbrushing, a lower level of halitosis; and nonsurgical treatment of scaling were effective in reducing halitosis; age was associated with the tongue coating index. Therefore, it will be necessary to perform good oral care and reduce the amount of dental plaque and tongue coating and undergo regular scaling with the objective of improving oral health and reducing halitosis.

This study was conducted to compare solo eating perceptions and dietary behaviors in the Seoul and Gyonggi-do regions according to gender. The study focused on the dietary perceptions, solo eating, eating together, dietary habits, food intake patterns and 38 keywords pertaining to solo eating. Of 411 subjects, 207 (50.4%) were males and 204 (49.6%) were females. The biggest problem that respondents perceived in their dietary life was irregular eating. Women prepared meals more often than men (p<0.001) and ate more instant and frozen food than men (p<0.05). Both males and females missed breakfast most, and the amount of the population eating breakfast alone ranked second highest. Women had lunch alone more often than men, while men ate dinner alone more often than women (p<0.01). All respondents spent 5~15 min when eating alone. Women avoided excessive smoking and drinking more than men (p<0.001). Men related key words regarding solo eating with negative emotions such as 'lonely', 'boring', and 'feel sorry when I see someone eating alone in a restaurant' more than women. Conversely, women related more positive key words with eating alone such as 'free', 'joy', and 'my own time'. Dietary lives of Koreans have rapidly changed along with social changes. Our research findings will contribute to increased comprehensive menu development and HMR development in the foodservice industry.

Adequate vitamin $B_2$, vitamin $B_6$, folate and vitamin $B_{12}$ intakes are known to be important for the growth and development in infants. The purpose of this study was to evaluate concentrations of vitamin $B_2$, vitamin $B_6$, folate and vitamin $B_{12}$ in human milk and to investigate the relationship between vitamin B levels in human milk and dietary habits and other health-related behaviors. Milk samples were obtained from 38 healthy lactating women (aged 29.0 $\pm$ 3.2 years) who are participating in the cohort study on pregnant women. Vitamin $B_2$ concentrations in human milk were positively correlated with maternal vitamin $B_2$ intakes in lactating mothers. Vitamin $B_6$, folate and vitamin $B_{12}$ concentrations in human milk were not correlated with maternal B vitamin intakes. Vitamin $B_6$ concentrations in human milk were negatively correlated with the amount of postpartum weight loss. The vitamin B concentrations in human milk were not associated with maternal age, height, weight and parity. Mothers who were exposed to indirect smoking had lower vitamin $B_2$ concentrations, and those who reported to consume health foods had higher vitamin $B_2$ concentrations in their milk. In conclusion, lactating women need to consume more vitamin B intakes for the growth and development in infants. Further researches are needed to find other diet and health-related factors which influence on B vitamin concentrations in human milk.

In present study, the authors investigated the possible effect of coffee consumption on serum cholesterol level in 1017 men between the ages of 40 and 59 years, who were randomly selected from the members of Seoul Cohort Study. Serum total cholesterol data was collected with other serologic indices (e.g. systolic blood pressure, diastolic blood pressure, hight, weight, etc.) through the program of biennial health check-up offered by Korean Medical Insurance Corporation (KMIC). The amount of coffee consumption was assessed by a self-administered questionnaire through mailing. Other confounding factors, such as age, body mass index, cigarette smoking, alcohol consumption, physical activity, and other dietary intake pattern were also determined by the questionnaire. The differences in means of serum total cholesterol in compared to non consumers were $-0.4{\pm}3.56mg/dl$ for those drinking less than 1 cup a day, $-0.6{\pm}3.60mg/dl$ for those drinking 1 cup a day, and $7.1{\pm}3.41mg/dl$ for those drinking more than 2 cups a day. Since smoking interacted the relationship between coffee consumption and serum total choleaterol, we re-analyzed those relationship in smokers and non-smokers separately Other atherogenic behaviors were well correlated with total cholesterol, so we adjusted the mean values of serum total cholesterol through multivariate model selection with age(r=0.12), total cigarette index (cigarette-years; r=0.10), Quetelet's index ($Kg/m^2$, r=0.16), daily calory expenditure (kcal/day, r=0.06), weekly meat and poultry consumption(g/week, r=0.05), weekly fish consumption (g/week, r=0.08), other caffeinated beverage intake (cups/week), and the amount of sugar and prim added to the coffee. Among those variables only age, Quetelet's index, fish consumption, and total cigarette index (in smokers) were remained in the models. After adjustment, the corresponing differences of total cholesterol in smokers were changed to $0.4{\pm}5.24mg/dl,\;-0.5{\pm}4.97mg/dl,\;and\;8.9{\pm}4.78mg/dl$, which were significantly different among themselves (P=0.011). In non-smokers, however, the differences were not statistically significant (P=0.76). Adjusted mean values of systolic blood pressure and diastolic blood pressure were also determined to evaluate the direct effect of coffee to cardiovascular system, but their means were not significantly different by coffee consumption(p=0.18 for SBP, p=0.48 for DBP). Asuming instant coffee in the most popular type of coffee in Korea, the association observed in our study between coffee and serum total cholesterol, especially in smokers, is very interesting finding for the connection between coffee and serum total cholesterol, because only 'boiled coffee' tend to show significant lipid raising effect rather than to other types of coffee, like filtered or espresso, in most of the western countries. We concluded that people who drink coffee more than 2 cups a day have significantly higher serum total cholesterol level than those who never drink coffee, especially in smokers.
