붕장어(Conger myriaster)는 2018년 6월부터 2019년 5월까지 거제 구조라, 망치 인근해역에서 장구형통발을 이용하여 매달 1회 채집해 이용하였으며, 항문장(Preanus length)과 습중량을 각각 0.1 cm, 0.1 g까지 측정한 뒤 위를 적출하여 가능한 종 수준까지 분석하였다. 위내용물 분석결과는 각 먹이생물에 대한 출현빈도(%F), 개체수비(%N), 습중량비(%W)를 구하여 상대 중요도지수비(%IRI)로 수치화하여 주 먹이생물과 크기군에 따른 먹이조성 변화를 알아보았다. 붕장어의 가장 중요한 먹이생물은 어류(Pisces)였으며, 그중 멸치(Engraulis japonicus)가 가장 우점한 먹이생물로 확인되었다. 그 외, 새우류(Macrura), 패충류(Ostracoda), 갯지렁이류(Polychaeta), 게류(Brachyura) 등 다양한 먹이생물을 섭식하였지만 그 양은 많지 않았다. 과거 광양만에서 이루어진 연구에서는 붕장어의 주 먹이생물이 날개망둑(Favonigobius gymnauchen)으로 나타나 이번 연구결과와 다소 차이가 있었다. 성장에 따른 위내용물 조성의 변화를 살펴본 결과, 뚜렷한 먹이전환이 나타나지 않았다. 붕장어는 성장함에 따라 개체당 평균 먹이생물의 개체수(mN/ST)는 통계적으로 유의한 차이를 보이지 않았으나, 평균 먹이생물의 중량(mW/ST)은 붕장어의 항문장이 증가함에 따라 유의하게 증가하는 경향을 보였다.

The aim of this study was to evaluate the methylation status of three important cancer related genes viz. p16, E-cadherin and hMLH1 promoters and to associate the findings with specific dietary habits in Kashmiris, a culturally distinct population in India, with gastric cancer. The study subjects were divided into three age groups viz. 0-30yrs ($1^{st}$), 31-60yrs ($2^{nd}$) and 61-90yrs ($3^{rd}$). A highly significant association between the intake of local hot salted tea in $2^{nd}$ (p=0.001) and $3^{rd}$ (p=0.009) age groups was observed with the promoter hypermethylation of E cadherin. Again a highly significant association between the aberrant methylation of hMLH1 (p=0.000) and p16 (p=0.000) promoters and the intake of local hot salted tea was observed in the $2^{nd}$ age group of gastric cancer patients. The intake of sun-dried food was also significantly associated with the promoter hypermethylation of E cadherin (p=0.003) and p16 (p=0.015) genes in $3^{rd}$ age group. The results of the present study suggest a close association between the aberrant methylation of p16, E-cadherin and hMLH1 promoters and the intake of local hot salted tea and sun-dried foods in Kashmiri population.

Objectives: This study was performed to identify the current barriers of obesity management for children using Community Child Care Centers and their caregivers (parents and teachers working in the Centers). Further, this study explored the possibility of utilizing a mobile phone application for tailored obesity prevention and management programs to overcome the current difficulties associated with children's obesity management. Methods: The qualitative data were collected through in-depth interviews with 20 obese and overweight children or children who wanted to participate in this study using Community Child Care Centers, 12 teachers working at the Centers, and a focus group interview with five parents of children using the Centers. Data were analyzed with a thematic approach categorizing themes and sub-themes based on the transcripts. Results: The current barriers of obesity management of obese and overweight children using Community Child Care Centers were lack of self-directed motivation regarding obesity management (chronic obesity-induced lifestyles and reduced self-confidence due to stigma) and lack of support from households and Community Child Care Centers (latchkey child, inconsistency in dietary guidance between the Center and household, repetitive pressure to eat, and absence of regular nutrition education). Mobile phone applications may have potential to overcome the current barriers by providing handy and interesting obesity management based on visual media (real-time tracking of lifestyles using behavior records and social support using gamification), environmental support (supplementation of parental care and network-based education between the Community Child Care Center and household), and individualized intervention (encouragement of tailored and gradual changes in eating habits and tailored goal setting). It is predicted that the real-time mobile phone program will provide information for improving nutritional knowledge and behavioral skills as well as lead to sustainable children's coping strategies regarding obesity management. In addition, it is expected that environmental factors may be improved by network-based education between the Community Child Care Centers and households using the characteristics of mobile phones, which are free from space and time constraints. Conclusions: The tailored education program for children using Community Child Care Centers based on mobile phones may prevent and reduce childhood obesity by overcoming the current barriers of obesity management for children, providing environmental and individualized support to promote healthy lifestyles and quality of life in the future.

The purpose of this study was to investigate fast-food consumption and it's nutrient density, and the correlation between subject's characteristics and consumption frequency of fast-foods among middle school students. The questionnaires were distributed to 150 male and 190 female students in Cheongju city. The data were analyzed using SAS and statistics used were percent of frequency, $X^2$-test, t-test, and pearson's correlation coefficient. The main reasons for using fast-food restaurants were 'good taste' and 'convenience'. The major concerns when the subjects choose fast-foods were 'taste ($65.9\%$), price ($20.3\%$) and 'nutrition'($6.0\%$). The consumption pattern of fast-foods go as follows: twice a month ($42.3\%$), once a week ($31.5\%$), and less than once a week. The number of fast food items that the subjects ate for one meal was two ($46.0\%$) or three ($33.2\%$). The most frequently chosen combination of foods for number of two choices was beefburger and cola. The mean average energy intake from fast foods for one meal was 620.7 kcal for male, 504.5 kcal for female. The energy ratio of carbohydrate : protein fat from fast foods was 49 : 14 : 43, which means fat intake is much higher than recommended level ($20\%$). Fiber was appeared to be the lowest on the nutrient density which was $17.7\%$ of the recommended level for Koreans, vitamin C was next ($22.8\%$ for male, $20.1\%$ for female). In mineral, iron was the lowest ($71.8\%$ for male, $67.1\%$ for female), and protein was over $100\%$ for both males and females. Frequency of fast food intake was positively correlated with eating frequency of the salty, the sweets, him, caffeine containing foods, instant noodles, and cookies. In conclusion, frequent consumption of fast foods can lead unbalanced nutrient intakes for middle school students, and those who consumed fast foods frequently showed undesirable food habits in their daily meal. Therefore, nutrition education for middle school students should be needed to encourage them to choose more nutritious food and have healthier dietary pattern.

Quercetin and naringenin are representative flavonoids that not only exert anti estrogenic, cholesterol-lowering and antioxidant activities but also can modulate the metabolism of many xenobiotics. The activity of the specific form(s) of CYP450 is likely to be a major determinant of susceptibility to chemically induced carcinogenesis between which varies among between individuals due to different dietary habits as well as genetic characteristics. People consume cooked meat or fish together with various vegetables containing substantial amounts of quercetin and naringenin that can modify the enzyme activity of CYP1A2 to stimulate or to inhibit the mutagenic activities of HCAs. Heterocyclic amines (HCAs) produced by cooking meat products at high temperatures are promutagens that are activated by cytochrome P450 (CYP) lA2. Using a newly developed Salmonella typhimurium TA1538/1A2bc-b5 strain, we tested the effect of quercetin and naringenin on the mutagenicity of 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ). TA1538/1A2bc-b5 bears two plasmids, one expressing human CYP1A2 and NADPH-P450 reductase (NPR), and the other plasmid which expresses human cytochrome b5 (cyp b5). TA1538/1A2bc-b5 cells showed high activities of 7-ethoxyresorufin O-deethylase (EROD) and methoxyresorufin O-demethylase (MROD) associated with CYP1A2 and are very sensitive to mutagenesis induced by several HCAs. MeIQ was found to be the strongest mutagen among the HCAs tested in this system. Mutagenicity of MeIQ was enhanced 50 and 42% by quercetin at 0.1 and 1 mM, respectively, but suppressed 82% and 96% at 50 mM and 100 mM. Naringenin also increased the MeIQ-induced mutation about 37% and 22% at 0.1 and 1 mM, but suppressed it 32% and 63% at 50 mM and 100 mM concentrations, respectively, in TA 1538/1A2bc-b5 cells. Thus, they stimulated the MeIQ induced mutation at low concentrations, but strongly suppressed it at high concentrations. This biphasic effect of flavonoids was due to the stimulation or the inhibition of CYP1A2 activity in a dose-dependent manner judging by the activities of EROD or MROD in the Salmonella cells. Collectively, it is likely that the biphasic effects of quercetin and naringenin on the MeIQ-induced mutagenesis in S. typhimurium TA1538/CYP1A2bc-b5 were due to their differential modification of the CYP1A2 activity in these cells.

The purpose of this study was to find out the common characteristics of eating behaviors of the long-lived elderly in order to offer the basic data for establishing dietary guidelines for a long and healthy life for the general population. The subjects were three-hundred elderly people over age 85 living in Kyungpook Sung-ju who have no problems in daily living. The general characteristics, nutrition knowledge and attitudes, meal patterns, and food preferences of the subjects were surveyed by individual intervies. The levels of the nutrition knowledge of the subjects were very low(average score ; 4.3) and the correlation coefficient between their nutrition knowledge and attitude score was also low(r=0.323, p=0.000). Most of the subjects(93%) had a regular meal pattern consuming three meals a day. The major staple food was rice mixed with other grains(75%) and the number of side dishes was mostly under four(99%). A majority(73%) had no habit of overeating and 51% of the subjects were taking snacks besides regular meals. Thirty one percent of the subjects had drinking habits and 80% of the drinking subjects had over 40 years of drinking history. The most common frequencies for intakes of various food groups were ; more than once a day(95%) for vegetables ; 2∼3 times a week(74%) for green and orange color vegetables ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2∼3 times a week(49%) for milk ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2-3 times a week(49%) for milk ; 2-3 times a week(85%) for seaweeds and 2-3 times a week(81%) for foods cooked with oil. The most preferred foods by the subjects were white rice(staple foods), soybean paste soup(soups), beef and eggs(meats and eggs), yellow croaker and hair tail(fish and shellfish), yoghurt(milk and milk products), all vegetables except carrot(vegetables), and watermelon(fruits). The popular food preparation methods included mixing with seasonings and the most preferred taste was sweet. The results showed that the eating pattern of long-lived elderly was characterized by regularity, simplicity, and no overeating.

교정치료 중 구강 내 환경 변화를 파악하기 위하여 교정치료 시작 후 24개월까지의 임상적 구강위생지수 및 타액, 구강 내 미생물의 변화양상을 평가하였다. 30명의 환자를 대상으로 하여, 임상적 구강위생지수(DMFS [decayed, missing and filled surfaces], O'Leary's plaque index, plaque pH), 타액의 변화(비자극/자극시의 타액량, 완충능(buffer capacity), pH, 잠혈(occult blood)류량, 구강 내 미생물(Streptococcus mutans, Lactobacillus) 변화를 파악하였다. 추가적으로 설문지를 이용하여 구강위생관리 및 식습관을 평가하였다. 분산분석, 회귀분석 및 Spearman의 상관분석을 통해 데이터를 분석하였다. 교정치료 도중 DMFS 값은 유의성있게 증가한 반면, plaque index는 감소하였고, plaque pH는 산성을 나타내었다 (p = 0.23). 비자극 시 타액량은 치료 중 유의성있게 변화하였으며 (p = 0.13), 자극 시의 타액량은 여성에서 장치 부착 이후 증가하는 양상을 보였다. Buffer capacity는 남성에서 치료 도중 감소되었으며, 타액의 pH는 유지되었다. 구강 내 미생물 및 잠혈류량은 고위험 수준까지 증가하였으며 성별의 차이는 나타나지 않았다 (p > 0.05). 치료 전 plaque와 구강위생용품의 사용 (r = 0.429; p = 0.018), 최종 DMFS와 비자극 시의 타액량 (r = -0.372; p = 0.043) 간에 뚜렷한 상관관계가 확인되었다. 교정장치의 부착으로 인해 구강 내 미생물은 증가하고, plaque pH는 산성화되어 치주조직의 손상이 일어나게 되었다. 또한 Buffer capacity는 변하지만, 치료 기간중의 타액의 pH는 유지되었다.
