In this study, the effects of the intake of Prunus sargentii R. seed oil on the lipid levels of mouse blood were compared to the effects of commercially available corn oils. Mice from the same purchase lot were separated into 3 groups [control (n=5), corn oil-treated group (n=5), and Prunus sargentii R. seed's oil-treated group (n=5)] of equal size. The oil-treated groups of mice were fed their respective supplemented diets for a total of 8 weeks. Prunus sargentii R. seed oil is high in palmitic acid, oleic acid, and linoleic acid. The kidney weights of mice fed Prunus sargentii R. seed oil were higher than those fed corn oil (p<0.05). The HDL-cholesterol (high density lipoprotein cholesterol) levels in mice fed Prunus sargentii R. seed oil ($124.40{\pm}20.19$mg/dl) were higher than those of mice fed corn oil (p<0.05). The total cholesterol level was highest in mice fed Prunus sargentii R. seed oil, but the LDL-cholesterol (low density lipoprotein cholesterol) level was lowest in mice fed Prunus sargentii R. seed oil. Therefore, Prunus sargentii R. seed oil may be a good resource as a natural oil material.

Since Korean ancient times, powder of Rosa rugosa Thunberg has been used as a folk remedy. This study was conducted to verify the effects of Rosa rugosa Thunberg powder on in vitro antioxidant properties and serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. In the case of Rosa rugosa Thunberg powders, measurement of TPC, ABTS radical scavenging activity of trolox, DPPH radical scavenging activity, and measured value of FRAP were higher in ethanol extract than water extracts. For LDL-cholesterol concentration, mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a high numerical value compared with other groups (p<0.05). When testing for triglyceride concentrations in blood, mice fed 10% and 20% powder of Rosa rugosa Thunberg with high-fat diets showed the lowest numerical values (p<0.05). When testing for blood insulin concentrations, the high-fat diet group showed higher levels than compared to the control group (p<0.05). When testing for blood leptin concentrations, the high-fat diet group was $5.88{\pm}3.53ng/dL$, whereas mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a blood leptin level of $10.36{\pm}5.96ng/dL$ (p<0.05). Therefore, results prove that powder of Rosa rugosa Thunberg reduces triglyceride concentrations in the blood, and could be used as an excellent natural antioxidant in the future.

In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of $10.74{\pm}0.56%$, ash $9.67{\pm}0.56%$, crude protein $25.24{\pm}1.02%$, and crude fat $2.66{\pm}0.08%$. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

The purpose of the present study was to investigate the relationship between social cognition (interpersonal problem-solving ability) and social competence. Subjects were 142 male and 148 female fifth graders randomly selected from two elementary schools located in Seoul and their fathers. The children and fathers were administered the Means-Ends Interpersonal Problem-Solving (MEPS) test and the Social Competence Scales based on Choi`s inventory(1992). The results indicated significant positive correlations between two subvariables (capability and leadership) of social competence and MEPS. Girls showed significantly higher MEPS scores than boys in the variables of overall problem solving, effective problem solving, and dependent strategy.

서울지역 여대생의 BMI를 기준으로 식생활, 영양섭취상태 및 혈액인자 비교 연구

최경순(Kyung Soon Choi),신경옥(Kyung Ok Shin),정근희(Keun Hee Chung) 한국식품영양과학회 2008 한국식품영양과학회지 Vol.37 No.12

본 연구는 20∼24세의 여대생 대상으로 비만유형에 따라 각 군별로 식습관과 식생활 평가, 영양섭취상태 및 혈액인자가 건강에 어떠한 영향을 주는지를 조사하였다. 체질량지수 (BMI)에 따라 저체중군, 정상군, 비만군으로 분류하였을 때, 신장은 군 간에 유의적인 차이가 없었지만, 체중·골격근량ㆍ체지방량ㆍ제지방량ㆍ체지방률 및 waist-hip ratio는 비만군에서 가장 높았다(p<0.05). 조사대상자의 식습관은 매일 아침식사를 하는 경우는 129명 중 저체중군은 36명 27.9%, 정상군은 88명 68.2%, 비만군은 5명 3.9%로 나타났으며, 전체 조사대상자의 아침 식사의 결식률도 15.3%나 되었다. 아침 결식의 이유로는 아침시간이 바쁘거나, 늦게 일어나서 아침을 거르는 경우가 많았으며, 결식으로 인한 배고픔을 간식으로 대체하고 있어 하루에 1~2회 정도 간식을 한다고 답하였다. 식생활 평가를 보면, 저체중군에 속하는 여대생들은 육류, 생선, 알류 등의 단백질 식품의 섭취(23.4%)와 과일 및 과일주스의 섭취(37.8%)를 많이 하는 경향을 보였으며, 비만군에 속하는 여대생들은 삼겹살, 갈비 등 지방이 많은 육류를 주 2회 이상 먹는 비율(77.8%)과 김치 및 채소를 식사 때마다 먹는 비율(66.7%)이 다른 군에 비해 높았다(p<0.05). 그러나 비만군에 속한 여대생의 경우 모든 식품을 골고루 섭취하려고 많은 노력을 하였으며, 저체중군에 비해 오히려 비만군에서 식생활과 건강에 더 많은 관심을 보이고 있는 것으로 나타났다. 영양소 섭취상태 중 콜레스테롤 섭취량은 오히려 다른 군에 비해 비만군에서 낮았고(p<0.05), 전체 여대생의 영양소 섭취상태를 한국인 영양섭취기준과 비교해 볼 때, 철, 칼슘, 섬유소의 섭취는 제시된 기준치에 비해 현저히 낮았으며, 소디움의 섭취는 오히려 기준치에 비해 과다하게 섭취하는 것으로 나타났다. 혈액 검사 결과 혈중 총콜레스테롤, HDL-cholesterol 및 HDL-C/LDL-C(ratio)는 비만 군에서 낮았으며, 중성지방 수치는 다른 두 군에 비해 비만 군에서 매우 높은 수치를 나타내었다(p<0.05). 혈중 총콜레스테롤은 각각 HDL-cholesterol 및 LDL-cholesterol과 정의 상관관계를 보였으며, 중성지방은 HDL-cholesterol과 역의 상관관계를 보였다. 따라서 본 연구의 결과를 보면, BMI에 의해서 분류된 세 그룹 모두에서 아침 결식률과 운동부족이 문제가 있는 것으로 나타났다. 저체중군에서는 균형적인 영양섭취가 요구되는 것으로 나타났고, 비만군에서는 너무 본인의 신체적 문제를 의식하여 식품의 섭취에 있어서 균형적인 식사를 무시하고, 체중을 줄이려고 편식을 시도하려는 경향이 있는 것이 문제점으로 지적되었다. 따라서 저체중군, 정상군 및 비만군에 상관없이 여대생의 현실에 맞는 전반적인 식생활의 개선과 건강 증진을 위한 영양교육 강화의 필요성 및 체계적인 식사관리 프로그램이 요구됨을 알 수 있었다. 또한 비만인 뿐만 아니라 저체중의 비율도 높아 자신의 건강상태를 올바르게 판단하여 자신에게 맞는 식생활 계획을 세우는 것이 필요하다고 사료된다. The objective of this study was to investigate the effect of obesity on health by analyzing the factors which are related to obesity through the questionnaires on the dietary pattern, nutrient intake and physical measurements. The subjects, 419 college women aged 20 to 24 year-old, were randomly selected from Seoul and data were collected during March to May, 2008 and classified as under underweight, normal weight, and obesity groups according to BMI. However, weight, skeletal muscle mass, body fat mass, fat free mass, percentage of body fat, and waist to hip ratio showed significant differences among all the groups (p<0.05). In the obese group, 77.8% ate fat-rich foods such as galbi and samgyopsal more than two times per week, 66.7% ate vegetables other than kimchi (p<0.05) as compared to the underweight and normal groups by mini dietary assessment (p<0.05). The cholesterol intakes of the underweight, normal weight, and obese groups were 164.67±114.52 ㎎/㎗, 143.31±99.58 ㎎/㎗, and 121.92±54.91 ㎎/㎗, respectively, and the obese group had a significantly lower intake than the other groups (p<0.05). The serum total cholesterol levels of the underweight, normal, and obese groups were 177.04±26.36 ㎎/㎗, 189.46±29.05 ㎎/㎗, and 170.00±12.75 ㎎/㎗, respectively, and the obese group showed lower total cholesterol level than the other groups (p<0.05). The triacylglycerol level of the obese group (132.00±64.60 ㎎/㎗) was significantly higher than the other two groups (p<0.05). The HDL-cholesterol levels of the underweight, normal weight, and obese groups were 51.92±9.39 ㎎/㎗, 59.20± 13.53 ㎎/㎗, and 43.00±8.98 ㎎/㎗, respectively, showing that the obese subjects had significantly lower HDL-cholesterol levels as compared to the subjects in the other groups (p<0.05). The HDL-C/LDL-C ratios of the underweight (0.52±0.45) and normal weight (0.59±0.23) groups were higher than the ratio of the obese group (0.41±0.06). Total cholesterol were positively correlated with LDL-cholesterol (r=0.768, p<0.01), but triacylglycerol were adversely correlated with HDL-cholesterol. In conclusion, our results show that college-aged women in Seoul should be encouraged to amend their overall dietary habits, make a dietary plan that fits their individual needs, and maintain an effective exercise schedule.

읽기이해부진아동의 의미 처리 특성

최경순(Kyung-Soon Choi),황민아(Mina Hwang) 한국언어청각임상학회 2010 Communication Sciences and Disorders Vol.15 No.2

배경 및 목적: 많은 선행 연구들에서 읽기이해부진아동의 언어능력의 결함을 보고하였다. 그러나 이들의 단어수준에서의 의미처리과정을 알아본 연구는 드문 실정이다. 본 연구에서는 한국어 사용하는 읽기이해부진아동의 내재적인 단어의미처리 과정을 어휘판단을 이용한 점화과제를 사용하여 알아보았다. 방법: 연구대상은 초등학교 4학년 이상의 읽기이해부진아동 15명과일반아동 15명으로 총 30명이었다. 점화단어 및 목표단어의 의미관련성에 따라 구성된 의미관련조건과 의미무관련조건에서 목표단어에 대한 어휘판단과제를 컴퓨터로 실시하였다. 결과:읽기이해부진아동과 일반아동 모두에게서 점화효과가 관찰되었다. 그러나 읽기이해부진아동은 일반아동에 비하여 전반적인 어휘판단시간이 느렸다. 논의 및 결론: 두 집단 아동에게서모두 나타난 의미점화효과에 근거할 때 읽기이해부진아동은 일반아동과 비슷한 양상으로 단어의미 활성화가 이루어지는 것으로 보인다. 그러나 읽기이해부진아동의 전반적으로 느린 어휘판단시간을 미루어 볼 때 일반아동에 비하여 단어의미 활성화의 효율성이 낮음을 확인할수 있었다. Background & Objectives: It has been reported in many studies that children with poor reading comprehension (poor comprehenders) exhibit impairments in various language skills. However, such reports are mostly based on their performances on standardized language tests and studies tapping their underlying language processing are limited. In the present study, we investigated whether Korean-speaking poor comprehenders exhibit semantic priming effect during lexical decision tasks. Methods: Fifteen poor comprehenders in grades 4-6 and 15 typically developing children participated in the study. The children were asked to perform a lexical decision task on target words preceeded by either semantically related words or unrelated words. Both the target words and the preceeding priming words were visually presented on a computer screen. Results: Both the poor readers and typically developing children showed a semantic priming effect where there lexical decision times on target words following semantically related words were significantly master than those following unrelated words. However, the poor readers were significantly slower than the typically developing children in the overall lexical decision times. Discussion & Conclusion: The significant effects of semantic priming in both groups indicate that the processing pattern of word meaning appeared to be similar in both groups of children. However, slower lexical decision times of the poor readers indicate that their processing of word meaning may be less effective than typically developing peers
