The purpose of this study was to assess the diet diversity, food habit and nutrient intake of obese adults who were visiting the health promotion center. This study was accomplished with the 138 obese adults (men = 103, women = 35) aged over 20 years old whose BMI were above 25 kg/m2. Nutrient adequacy ratio (NAR), the number of foods (Dietary Variety Score, DVS), and food group consumed (Dietary Diversity Score, DDS) by using the data from the three days record were analyzed and the food habit and lifestyle were assessed by self reporting questionnaire. The average energy intake of men was 2150.2 kcal which was significantly higher than that of women (p < 0.05). The intake ratio of carbohydrate, protein and fat over total energy was 54.8% : 19.3% : 25.8% in men, 59.5% : 17.8% : 22.6% in women, respectively. Frequency of the breakfast in a week above 4, 2~3 time and under one time was 75.7%, 10.7% and 9.7% in men, 77.1%, 5.7% and 14.3% in women respectively. Frequency of eating between meals in a day under one time was 73.8% in men, 57.1% in women (p < 0.05). The average DDS and DVS was 3.63 ± 0.07 and 14.10 ± 3.45, respectively which was significantly correlated with MAR (r = 0.40 in DDS, r = 0.64 in DVS, p < 0.01). The most frequent style of food pattern was DMGFV = 01101 in 35% of men, and DMGFV = 01111 in 37.1% of women. Our results show that dietary diversity and variety are useful parameters for evaluating nutrient intakes in obese adults. These findings suggest that nutritional education based on obese persons` eating behavior and eating diversity may be required to increase educational efficiency of weight control programs.

Elevated serum concentration of inflammation markers is known as an independent risk factor of metabolic syndrome (MS) and dietary intake is an important factor to control MS. The purpose of this study was to investigated the hypothesis that inflammatory indices are associated with dietary intake and diet quality index-international (DQI-I) in subjects with MS. A cross-sectional study was conducted on 156 men and 73 postmenopausal women with MS, defined by three or more risk factors of the modified Adult Treatment Panel III criteria. Serum levels of high sensitive C-reactive protein (hs-CRP), adiponectin were examined and nutrients intake and DQI-I were assessed using a semiquantitative food frequency questionnaire. The total DQI-I score was significantly higher in female subjects (65.87 ± 9.86) than in male subjects (62.60 ± 8.95). There was a positive association between hs-CRP and polyunsaturated fatty acid intake (p < 0.05) and a negative association between adiponectin and lipid (p < 0.05), total sugar (p < 0.01), and total fatty acids (p < 0.05). When the subjects were divided into 5 groups by quintile according to serum adiponectin and hs-CRP level, there was no association between DQI-I score and hs-CRP levels. Moderation score of DQI-I was significantly higher in highest quintile group than the lower quintile groups. Therefore, our results provide some evidence that dietary intake and diet quality are associated with inflammation markers and dietary modification might be a predictor to decrease risk for metabolic syndrome complications. However further research is needed to develop the dietary quality index reflecting the inflammatory change by considering the dietary habit and pattern of Koreans.

본 논문은 DC모터와 Bluetooth모듈을 통해 직접 조종하여 움직이는 알람시계 형태로 로봇을 제작하여 단순한 알람시계가 아닌 재미와 편의를 제공하는 알람시계 로봇을 제안한다. Arduino Uno 보드(ATmega328 기반의 마이크로컨트롤러 보드)와 DC모터를 이용한 로봇 본체, 스마트폰과 통신하는 bluetooth모듈, 로봇을 작동하는 어플리케이션 등으로 구성된다. 알람이 작동되면서 랜덤하게 움직이는 로봇은 블루투스 통신으로 제어가 되고 사용자의 조종에 따라 움직인다. 로봇은 스마트폰과 블루투스 통신을 통해 받은 데이터로 조종되어 지정된 도착장소로 움직일 수 있다. 이러한 로봇을 제작하여 실생활에 상용화 가능하게 만들어 또 하나의 아이디어 알람시계가 되고자 하는 목표를 가진다.

본 연구는 프락토즈 중합체인 레반의 지질 감소 효과와 비만 유전자인 UCP를 통한 에너지 대사에 미치는 효과를 살펴보기 위하여 성장기 6주간 AIN-76A diet로 사육한 흰쥐에게 레반을 식이 섭취량의 1%, 2%로 5주간 경구투여하여, 혈중지질 수준과 체지방 형성 및 혈중 인슐린, 렙틴 농도와 갈색지방 조직, 백색지방 조직, 골격 근육, 시상하부에서의 UCP mRNA 발현량 변화를 관찰하였다. 연구 결과를 종합해 보면 다음과 같다. 1) 레반군에서 혈청 중성지방과 총 콜레스테롤은 감소하고 HDL 콜레스테롤 수준은 영향을 미치지 않아 1%와 2% 레반 공급이 지질 대사를 개선시킬 수 있음을 보여주었다. 2) 1%와 2% 레반군에서 내장 지방 무게가 감소하여 적은 양의 레반 공급으로 체지방 축적이 억제될 수 있음을 보여주었다. 3) 갈색 지방 조직과 부고환 지방, 복막 지방 무게는 그룹간 차이가 나타나지 않았다. 4) 혈청 인슐린 농도는 1% 레반군에서, 혈청 렙틴 농도는 1% 레반군, 2% 레반군에서 대조군에 비해 감소하는 경향을 나타내었으나 통계적 유의성은 나타나지 않았다. 5) 1%와 2% 레반 공급에 의하여 갈색 지방 조직과 골격근육, 시상하부에서의 UCP mRNA 발현량에는 변화가 없었다. 6) 백색 지방 조직의 UCP 2 mRNA 발현량이 레반 공급에 의해 증가하여 1%와 2% 레반 공급에 의해 에너지 소비율이 증가할 수 있음이 나타났다. 결론적으로 저농도의 1%와 2% 액상 레반 공급은 총 식이의 3%~5% 레반 공급과 비교하여 혈중 총 콜레스테롤과 중성 지방 감소 효과에는 차이가 있으나 UCP 발현 증가에 미치는 영향은 적은 것으로 보인다. 그러나 저농도의 1~2% 액상 레반 공급으로 지질 대사를 개선하고 체지방 축적을 어느 정도 억제하는 효과를 나타냄을 알 수 있으며 이에 관한 임상 연구로 레반의 고지혈증과 비만을 조절하는 기능성 식품 소재로서의 가능성 검색이 요망된다. This study described the effect of levan (β-2,6-linked fructose polymer) feeding on serum lipids, adiposity and uncoupling protein (UCP) expression in growing rats. Levan was synthesized from sucrose using bacterial levansucrase. UCP is a mitochondrial protein that uncouples the respiratory chain from oxidative phosphorylation and generates heat instead of ATP, thereby increase energy expenditure. We observed that 3% or 5% levan containing diet reduced serum triglyceride levels, visceral and peritoneal fat mass and induced the UCP expression in rats fed high fat diet in previous study. To determine whether the intake of low level of levan may have the hypolipidemic and anti-obesity effect, 4 wk old Sprague Dawley male rats were fed AIN-76A diet for 6 wk, and sub-sequently fed 1% or 2% levan solution for further 5 wk. Intake of 1% levan in liquid form reduced serum triglyceride and serum total cholesterol levels to 50% and 66% of control group, respectively. Although epididymal and peritoneal fat masses were not affected by levan feeding, visceral fat mass was lower in 1% levan group compared to control group. The expression of UCP2 mRNA in brown adipose tissue, skeletal muscle and hypothalamus and UCP3 mRNA in skeletal muscle were not changed by levan feeding, while the UCP2 mRNA in white adipose tissue was up-regulated by levan feeding. In conclusions, intake of low level of levan solution reduced serum triglyceride and total cholesterol, restrained the visceral fat accumulation and increased UCP expression in white adipose tissue in rats. This study suggests that hypolipidemic and anti-obesity effect of levan attributed to anti-lipogenesis and inefficeint energy utilization by up-regulation of UCPs.
