Purpose: This study examined whether there was a difference in the nutrients and food intake of young children depending on their lunch places. Methods: The dietary survey data of the fifth Korea National Health and Nutrition Examination Survey (2010 ~ 2012) were used. The children were grouped into either a child care center lunch group (n = 728) or home lunch group (n = 592) and their nutrients and food intakes were compared. Results: No differences in the 24-hr energy intake and energy intakes from lunch and dinner according to the lunch places were observed. The percentage of breakfast energy was lower in the child care center lunch group, whereas the percentage of snack energy was higher. In children aged 3 ~ 5 years, the sodium, potassium, and vitamin C intakes were high in the child care center lunch group. The 1 ~ 2 years and 3 ~ 5 year old children's vegetable intake from lunch was significantly higher in the child care center lunch group than in the home lunch group. Children aged 3 ~ 5 years in the child care center lunch group consumed more beans and fish at lunch. The adequacy of nutrients and food diversity of child care center lunch appear better than home lunch. Conclusion: Parents and care providers need to make efforts to use diverse foods, such as vegetables and fish, in children's meals to provide balanced diets and promote healthy eating behaviors to their children.

The maintenance of intestinal health is complex and relies on a delicate balance between the diet, the normal microflora and mucosa, including the digestive epithelium and overlying mucus layer. The colorectal mucosa is protected by a visco-elastic mucus gel formed by high molecular mass glycoproteins referred to as mucins. Abnormality of mucin have been identified with colorectal disease. Constipation increases with age, and is more common among women than men in all age groups, e.g. 10% of men and 20% of women in the USA. The aim of the present study was conducted to investigate that the effects of formulation KTG075 from edible plants on intestinal function on mucus secretion, were examined by loperamide-induced constipation method using Sprague Dawley male rats. Epithelial cells of colonic crypt contained more mucus in the KTG075 group compared with those of the control group and the thickness of the mucus layer stained with alcian blue was significantly thicker in KTG075 treated rats compared with in control rats. Mucus production of epithelial cells of crypt and mucus contents at fecal and mucosa surfaces were reduced by loperamide-induced constipation. These results indicates that a poly herbal formulation KTG075 accelerates evacuation and activated intestines.

In this study, the breads with medicinal herbs (MH) composites showing immunostimulating activity were prepared and their characteristics were examined. Fourteen kinds of medicinal herbs were extracted with hot water and divided into 3 groups (MH-1, MH-2, MH-3) based on their contents. All groups showed immunostimulating activity in terms of macrophage phagocytosis, nitrite production, cytostatic activity and cytokine production. In the preparation of breads containing MH extracts of various contents (0, 30, 50, 70, and 100%), there was no significant difference among dough pHs of all groups after first fermentation, but loaf volume was significantly (p<0.05) increased in 70% added group while decreased in 30%, 50%, and 100% added groups compared to the control. The "a" and "b" values of bread crumb increased with the content of MH extracts while "L" value decreased, but these values of bread crust were similar to the control group. Most improvements in hardness, adhesiveness, gumminess and chewiness of bread were noticed by the addition of 70% MH extracts, but those of springiness, cohesiveness and resilience were mostly by the 50% addition ones. Through the sensory evaluation, it was revealed that mouth feeling, taste and overall preference decreased at breads containing 70% and 100% extracts, although appearance and crumb texture were not significantly (p<0.05) different among all groups.

This study aimed to investigate the factors influencing the decision on whether to receive regular oral check-ups among the national health insurance beneficiaries with income and aged over 20 years in Korea. This was a cross-sectional study, using the data from the 2014 6th Korea National Health and Nutrition Examination Survey (KNHANES VI-2), conducted by the Korea Centers for Disease Control and Prevention. The final sample included 2,843 subjects who participated in the health examination survey and oral check-ups. The IBM SPSS Statistics ver. 20.0 was used for the statistical analysis, based on the complex sampling design. The Rao-Scott chi-square test was used to verify the difference in the distribution of independent variables with regard to oral check-ups. The binary logistic regression analysis was used to determine the influencing factors. The ratio of beneficiaries who received oral check-ups was less than half of those who received medical examinations. The Rao-Scott chi-square test, revealed significant differences in the age group (p<0.05) of the predisposing factors, toothache within a year (p<0.001), untreated dental caries (p<0.001) of the need factors, personal income level (p<0.001), educational level (p<0.001), type of medical insurance (p<0.001), and private health insurance (p<0.01) of the enabling factors. In the binary logistic regression analysis, factors influencing oral check-ups were age group, personal income level, educational level, toothache within a year, and untreated dental caries. These findings show a variety of factors influencing the utilization of regular oral check-ups.

The study was intended to investigate the factors affecting dental caries in adults. To that end, adults aged 19 years and older among 10,113 subjects who completed the health-related questionnaire, medical examination and nutrition surveys in the first year (2013) of the 6th Korea National Health and Nutritional Examination Survey, and 4,843 subjects categorized as patients with permanent teeth caries were included in the final analysis. The prevalence of dental caries in line with socio-economic aspects was found to be higher in men than in women. In view of education, the prevalence of dental caries was high in high school graduates, middle school graduates, college graduates and other advanced degree holders in the order named. Low monthly income earners showed the highest prevalence of dental caries. As for health-related lifestyles, the prevalence of dental caries was higher in smokers than in non-smokers. Obese subjects showed a little higher prevalence of dental caries compared to people of normal weight. Also, the prevalence was higher in those who failed to get oral examination than otherwise. Frequent daily toothbrushing and use of dental floss and interdental brush significantly decreased the prevalence of dental caries. In the logistic regression analysis with the presence or absence of dental caries employed as a dependent variable, gender, age, income level, smoking, oral examination and use of dental floss were found to serve as independent variables affecting dental caries. Therefore, Korean adults' socio-economic factors and lifestyles were proved to affect dental caries, which warrants some dental health programs and action plans designed to help lead healthy lifestyles whilst preventing dental caries and improving dental health in adults.

International Maritime Organization (IMO) is one of the most effective organizations in evolving international law for the protection and conservation of the marine environment. The IMO, MARPOL(Marine Pollution) 73/78 contains six Annexes that provide an overarching framework for the objectives of the international marine pollution. Annex IV was regulated by 64 th resolution in 2012 to control sea pollution from sewage. In 2014 large-scale wastewater treatment and nutrient removal device was developed with a grant from the Ministry of Oceans and Fisheries. A combined new process of Sequence Batch Reactor (SBR) and Membrane Bioreactor(MBR) was developed to overcome the pollution caused by shipboard sewage. In the present study, shipboard sewage wastewater was treated by mixing and aeration cycle in the newly developed SBR process. Furthermore, during analysis by NGS technique(Macrogen Co., Ltd.), dominant species of bacteria were found in the aeration tank of the Bench-scale wastewater treatment facility. Bacteroidetes and Gammaproteobacteria accounted for 27.1 % of the aerobicbacteria and 16.8 % of the anaerobicbacteria, respectively. Microorganisms play a vital role in shipboard wastewater treatment. A further detailed study is required to understand the precise role of the microorganisms in the wastewater treatment.

The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

In order to find out the possibility of utilizing red pepper seed as food resources of fats and proteins, a series of studies were conducted. The red pepper seed contained 27.6% of crude fat and 22.2% of crude protein. The lipid fractions obtained by silicic acid column chromatography were mainly composed of 95.4% neutral lipid, where as compound lipid were 4.6%. Among the neutral lipid separated by thin layer chromatography, triglyceride was 85.6%, sterol ester 4.9%, free fatty acids 3.4%, diglyceride 2.5%, sterol 2.2% and monoglyceride 1.1%, respectively. The predominant fatty acids of red pepper seed oil were linoleic acid (57.1-75.4%), palmitic acid (13.9-21.3%) and oleic acid (8.0-15.1%), especially glycolipid contained 1.7% of linolenic acid and small amount of myristic acid and arachidic acid. The salt soluble protein of red pepper seed was highly dispersible in 0.02M sodium phosphate buffer containing 1.0M $MgSO_4$, and the extractability of seed protein was about 25.0%. Glutamic acid and arginine were major amino acids of red pepper seed protein. The electrophoretic analysis showed 6 bands in seed protein, and the collection rate of the main protein fraction purified by sephadex G-100 and G-200 was about 62.2%. Glutamic acid (19.9%) was major amino acid of the main protein, followed by glycine and alanine. The molecular weight of the main protein was estimated to be 93,000.
