Objectives: Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Methods: Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

The purpose of this study was to investigate the effect of nutrition counseling on improving metabolic syndrome (MS) risk factors. Sixty-eight subjects were grouped according to their numbers of MS risk factors. Subjects who have three or more risk factors of MS were defined as "High risk", subjects who have two risk factors of MS were defined as "low risk", and subjects who have below two risk factors of MS were defined as "no risk" group. All groups finished nutrition counseling every three weeks for 12 weeks. Anthropometric, dietary assessments (24 hr-recall) and blood samples were measured at 0 and 12 weeks nutrition counseling. After 12 weeks of intervention, anthropometric data (weight, BMl, body fat (%), and waist/hip ratio) were significantly decreased (p < 0.05) in all groups. Daily consumption of calorie was decreased significantly (p < 0.05) in the group of low risk and high risk. Blood level of fasting plasma glucose was significantly decreased (p < 0.001) in all groups after 12 weeks of intervention. Significantly, the fasting plasma glucose level was returned to normal range in the high risk group. The number of people who have three or more risk factors of MS (high risk group) was decreased from 25 to 12. Sum of MS Criteria decreased from 85 to 52 in the group of MS and decreased from 143 to 99 in all groups. These results indicate that nutrition counseling for male workers at the worksite proved to be helpful by reducing the risk factors of MS and thereby reducing the risk of cardiovascular disease. Continuing and systematic nutritional management programs should be developed and implemented for male workers at the worksites.

Objectives: The purpose of this study was to investigate the behavioral modification of obese adults who underwent nutritional and physical activity education. Twenty obese females, aged 20-60 years old, with BMIs (Body Mass Index) >30 or body fat (%) >40 were subjected to this study. Methods: The physical activity education program consisted of doing exercise in a gymnasium together or home exercise. Dietary attitudes and dietary intakes were assessed using weight control, physical activity, and eating habits. The nutrition-exercise educational period was 12 weeks. Results: After the study period, there was significant improvement in physical activity and eating habits score. Furthermore, there was a significant increase in the dietary intakes of fiber, iron, potassium, vitamin A, vitamin $B_6$, and niacin. Blood pressure, blood glucose, and total cholesterol levels showed a tendency to decrease, but there was no significant difference. BMI, fat mass, abdominal circumference, and visceral fat levels were significantly reduced while muscle mass significantly increased. Conclusions: This study suggests that behavioral modification by nutrition and physical activity education with feedback has positive effects on dietary intake and anthropometric biomarkers in obese adults. Therefore, lifestyle interventions of this kind could be recommended as a method for obesity management.

In this study, a fish survey was conducted to investigate the habitat status of black shinner (Pseudopungtungia nigra) designated as endangered species level from the lower part of Yongdam Dam to the upper part of Daecheong Dam. Biodiversity analysis was performed on the basis of the number of fish emerged, and biological health and physical habitat environment were quantitatively analyzed using collected P. nigra. According to the survey, the habitat range of P. nigra was found from Banguri-myeon, Buri-myeon, Geumsan-gun, downstream of Yongdam Dam. The biodiversity analysis results of all species appeared to be low in overall dominance index and relatively high in species diversity and uniformity index. In addition, P. nigra collected in this study was confirmed to have normal growth and nutritional status by the full-length-weighted relativities and condition factor. The physical habitat environment of P. nigra was 0.3 - 0.6 m in depth, 0.3 - 0.7 m/s in flow rate, and bed materials showed high frequency of occurrence in the range of cobbles (64.0 - 256.0 mm) to boulders (>256.0 mm). These results are expected to be used as data for habitat restoration and management in the future as basic data on the spatial range and preferred physical habitat environment of P. nigra in Geumgang.

The amount of cellular components including soluble sugars, amino acids, organic acids and glucosinolates (GLS) was investigated during radish root processing to develop a radish beverage. The radish root was divided into two parts, white and green tissue, and processed separately by extracting the juice from the fresh tissue and from the boiled tissue to compare differences in the components content among the preparations. The overall palatability of both the fresh and boiled extracts from the green part of the radish was higher than that of the same extracts from the white part. The sweetness of extract by boiling increased and its pungency decreased, thereby the palatability increased by being compared to the fresh radish extract. The sweetness was affected by sucrose not by glucose or fructose of monosaccharides by showing different sucrose contents according to treatment comparing palatability. Malic acid was identified as primary organic acid, and the content was higher in both the fresh and boiled extracts from the white part than in the extracts from the green part of the radish. The fresh extract from the green part of the radish contained more essential amino acids, such as threonine and valine, and more hydrophilic amino acids including glutamic acid, aspartic acid, and arginine than those of the fresh extract from the white part, suggesting the green fresh part is more palatable than the white fresh part. The main sulfur compound was ethylthiocyanate in radish, and others were butyl isothiocyanate, dimethyl-disulfide, and 4-methylthio-3-butylisothiocyanate. The four GLS were detected much more in the fresh green and fresh white parts of the radish because they evaporated during boiling. The contents of the four sulfur compounds were higher in the white fresh part than in the green fresh part, which is likely the reason the pungency was higher and the palatability was lower in the white fresh part than in the green fresh part of the radish. The ascorbic acid content was higher in the fresh extract compared to the boiled extracts from both the green and white parts. Taken together, these findings indicate that fresh radish extract is superior to obtain in terms of retaining desirable nutritional and functional components for health.

Milk constituents and somatic cell count (SCC) were analysed for 4,059 milk samples from 178 dairy farms from April to December in 1999. Correlations among each milk constituents, milk urea (MU) concentration and SCC in association with lactation stage, milk yield and parity, and balancing status of nutrients' supplies were analysed, and the results are summarized as follows; Averages of milk fat percent, total solids percent and milk yield were $3.72{\pm}0.91%$, $12.50{\pm}1.31%$ and $23.80{\pm}8.54kg$, respectively, whereas those were significantly lower during the summer season. In contrast, average of MU concentration was $0.0361{\pm}0.0006%$ which was significantly higher during the summer season. With milk yield, concentrations of fat, protein and SCC in milk decreased but concentrations of lactose and urea in milk and body condition score (BCS) were not altered. Concentrations of fat, protein, lactose, total solids, SNF, and urea in milk were significantly affected by stage of lactation ($P{\leq}0.0001$) but SCC was not changed. Parity of dairy cows had a significant effect on concentrations of fat ($P{\leq}0.02$), lactose ($P{\leq}0.0001$), total solids ($P{\leq}0.002$), and SNF ($P{\leq}0.0001$) in milk and milk yield ($P{\leq}0.0005$) but did not change concentrations of urea and protein in milk. Somatic cell count had significant positive correlationship with percentages of fat, protein and total solids ($P{\leq}0.0001$), respectively, but had negative correlationship with percentages of urea and lactose in milk and milk yield ($P{\leq}0.0001$). Milk urea concentration was negatively correlated with concentrations of protein, fat, total solids, and SNF in milk and milk yield ($P{\leq}0.0001$) and, according to regression analysis using milk urea concentration and SCC, following equation was obtained; $Y(MU)=3.688{\times}10^{-2}-4.04{\times}10^{-7}{\times}X(SCC{\times}1,000)(r^2=0.0038$, $P{\leq}0.0001$). We studied balance between protein and energy supplies to dairy cows in each farm based upon milk urea and protein concentrations, and results showed that 137 of total 178 farms fed cows unbalanced amounts of dietary protein and energy.

This study was performed to compare nutrient intakes, diet quality and serum indices (TG, Total cholesterol, LDL-cholesterol, HDL-cholesterol, RBC, Hb, Hct, Serum iron, ferritin, MCV) of obese and normal weight children. The subjects were 149 children living in the Seoul and Gyeonggi areas. Each subject was assigned to one of such as normal weight group ($15th{\le}BMI$ percentile < 85th, n = 82) or obese children ($85th{\le}BMI$ percentile, n = 67) according to their percentile of BMI by The Korean Pediatric Society. Data on dietary intakes, body composition and serum indices were obtained. Differences of all the above variables were assessed. Energy, carbohydrate, fat, cholesterol, total fatty acid, SFA, MUFA, PUFA, phosphate, potassium, zinc, vitamin $B_1$ and vitamin $B_6$ intakes of girls in the obese group were higher than those of the normal weight group (p<0.05). The intake of fiber was as insufficient as below 50% of KDRIs in both groups. Nutrient adequacy ratio of calcium, iron, phosphate, zinc and folate in obese boys were lower than those of normal weight boys (p<0.05). Energy intakes of grain and milk and dairy food in the obese girl group ($905.9{\pm}344.5kcal,\;210.9{\pm}166.4kcal$) were higher than those of normal weight girls ($671.2{\pm}360.7kcal,\;184.0{\pm}103.5kcal$) (p<0.05). HDL-cholesterol level of obese boys ($52.7{\pm}6.3mg/dL$) was significantly lower than that of normal weight boys ($65.3{\pm}15.6mg/dL$). Serum iron level of obese boys and girls (boys: $79.4{\pm}32.6mg/dL$, girls: $98.3{\pm}16.2mg/dL$) was significantly lower than those of normal weight children (boys: $104.8{\pm}38.6mg/dL$, girls: $106.7{\pm}28.9mg/dL$) (p<0.05). These results suggest that there should be sensible food selection and more intakes of fruit and vegetable are needed to improve the nutritional status in obese children.

This study compared the food habits and attitudes towards dietary life culture in types of feeding management, gender and grade. The subjects were 352 elementary school students who lived in Seocheon, Chungnam. The independently managed school students were better than jointly managed school students in food habits (p<0.05). In skipping school meals, upper grade students were skipped more than lower grade students (p<0.05). In rate of eating school meals, boys were faster than girls (p<0.001). The independently managed school students and the jointly managed school students were different on distasteful food. Boys disliked vegetables and girls disliked cereals and beans (p<0.05). Upper grade students ate more well-balanced meals than lower grade students (p<0.05). As for the question 'what you will do if the distasteful foods are provided through school meals', they responded. the highest percent of students, 'I will try once or twice'. And the response 'I have them for health' was higher independently in managed school students than the jointly managed school students (p<0.05), girls than boy (p<0.05), and the lower grades than the upper grades (p<0.05). As for the question 'what you will do if the distasteful foods are provided, after the guide for school meals was performed', the response, 'I will make an effort to have it' accounted for the highest percents, and there were differences in lower grade students who were high percents than upper grade students (p<0.01). As for the recognition for unbalanced diets, most of the students recognized that it is a 'bad habit'; the girl students accounted for more percentage than boys (p<0.05). The criterion of food choice were different in gender and grade (p<0.01). As for the factor of influences for the food habits formation, lower grade students were 'school education' and upper grade students were 'parents' (p<0.05). Thus, the systematic guide for proper intakes of nutrition should be performed. Also, the time when students can be educated by an expert of nutritional education, which is connected with school meals and students can grow healthily.

Congenital Missing Teeth(hypodontia, oligodontia) is the developmental absence of one or more teeth. It has been reported as being the most common anomaly of dental development in human, relatively common in the permanent dentition. In a recent review, Vastardis has quoted incidence ranges of $1.6%{\sim}9.6%$ in the permanent dentition. Brook has quoted a prevalence of $3.5%{\sim}6.5%$ in most populations, with severe hypodontia, defined as the absence of six or more teeth, having a prevalence of $0.3{\sim}0.4%$. The most commonly affected teeth are third molars, followed by maxillary lateral incisor, and second premolars. The etiology is unknown, several hypotheses include trauma, nutritional deficiency, infection, metabolic abnormalities, systemic disease and genetic influence. The multiple congenital missing is commonly associated with specific syndrome or severe systemic abnormalities such as cleft lip & palate and Down's syndrome. These cases present that children have multiple congenital missing teeth in the permanent dentition, without any systemic disease. Management of this condition must be considered orthodontic and prosthodontic treatment comprehensively. In these cases, children were treated by space maintainer or orthodontic appliance and follow-up checked.

White rice consumption, a staple food for the Korean influence the other food consumption and nutrition balance. The aim of this study was to investigate the association with rice consumption based dietary intake and muscle mass for the Korean elderly who are easily in mal-nutrition. A total of 1,433 subjects (658 male and 775 female) 60 years or older from the fifth Korea National Health and Nutritional Examination Survey 2010 participated in this study. One of the findings was that there was association white rice consumption and marital status (single/with/without spouse) as well as education for men. Other interesting finding was the member of highest white rice consumption group showed higher muscle mass in both sexes. The other finding was that the more white rice consumption group showed the less meat consumption as well as the less consumption of other grains, noodle & dumpling, and flours & bread in both sexes. We found the significant association between white rice consumption level and muscle mass and several metabolic syndrome related factors in the elderly. But the association with white rice consumption and glucose metabolism related factor had not shown consistently.
