대전대학교 교양과목으로 개설된 ‘식생활과 다이어트’ 교과목을 수강하는 남녀 학생 151 명을 대상으로 다이어트 경힘과 함께 그들의 식습관을 알아온 결과는 다음과 같다 조사대상자는 남학생 81 명과 여학생 70명으로 총 151 명이었다. 남학생들의‘식생활과 다이어트’ 수강동기는 식생활 전반에 대해 공부하고 싶다는 응답이 여학생들은 특히 다이어트에 관심이 있어서 라고 응답한 학생이 가장 높아 유의적 차이를 보였다 여학생 중 51 .4%, 남학생 중54.3%는 다이어트에 대한 경험이 있었으며, 다이어트 해 본 시기는 남학생은 대학교 때 여학생은 고등학교 때가 가장 높게 나타나 유의적 차이를 보였다. 다이어트 정보는 남학생과 여학생 모두 인터넷과 경험 있는 친구 나 선배를 통해서가 가장 높게 나타났다. 남녀 학생의 평균 운동 시간은 유의적 차이를 보여 남학생은 주 1 - 3시간 운동하는 학생이 가장 많았고 여학생들의 주 1 시간미만 운동하는 학생이 많았다. 식생활 태도에 대한 조사에서 아침 식사를 하지 않는 학생이 남녀 각각 19.6%. 18.6%로 나타났다. 남학생이 여학생보다 과식하는 경향을 보였으며 간식을 먹는 횟수는 여학생이 많았다. 조사대상자 자신의 식생활의 개선점으로 남녀 학생이 각각 56 .4%와 47.0%가 불규칙한 식사로 답하였다. 이상의 결과로 남녀 학생들이 다이어트에 대한 관심도가 높았고 식습관에 문제가 있어 “식생활과 다이어트”과목을 수강함으로써 식습관과 다이어트 과목을 통한 영양교육이 효과가 있을 것으로 본다. In th is study, 151 students(male were 81 and female were 70enrolled in ‘' Food and Diet course were asked about their diet experiences and food habits . In the question asking the reasons for taking this‘' Food and Diet'class , most male subjects answered they enrolled 'to learn about overall knowledge’, whereas female students answered ' special interest in diet’' led to taking th is class. 67 .1 %of women and 64.2% of men said they put effort to maintain weight. Also , 51 .4%of female and 54.3% of male have experience of diet. The period of diet was most frequent in University for men (33 .3%) and in high school for women (47.1 %). Diet information was gathered from internet of from friends with previous experiences for both genders . It showed students gain little through reading nutrition related books , percentage was low for men and women (3 .7%. 1.4%, respectively). For diet methods. 40% of the subjects in total said they do diet through exercise. Female subjects showed that they've tried many different methods such as yoga and diet therapy . 53 .1 % of male and55.7% of female answered the diet was effective and lost weight. In the questionnaire about the dietary life and habits. percentage of the subjects who do not eat breakfast was 19.6% for men and 18.6% for women. The frequency of excessive eating and taking snacks was higher in men and it showed statistically meaningful result. From above results , we can conclude that the interest in diet was high in both gender and they both have problems regarding eating habits. 80 by taking ‘' Food and Diet’' class , it is predicted that this course will have educational effect on students 'eating habits and their diet.

단클론항체를 이용한 타액 내 Streptococcus mutans 수준의 측정

김추성,김재곤,양연미,백병주,이경열,김미아,임수민 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.2

Streptococcus mutans는 구강 내에 상존하는 치아우식증의 주요 원인균으로서 치면의 피막에 부착 후 glucan을 형성하여 세균의 군락을 이루며, 외부로부터 공급된 자당대사를 통하여 유기산을 생성함으로써 법랑질을 탈회시킨다. 치아우식 활성도의 평가를 위한 단클론항체를 이용한 방법은 진료실에서 빠른 시간 내에 간편하게 타액에 존재하는 Streptococcus mutans의 정량분석이 가능한 방법이다. 이 연구는 3세에서 6세 사이의 어린이 15명을 대상으로 자극성 타액을 채취하여 시판 중인 단클론항체를 이용한 Salivacheck Mutans, strip을 이용한 Dentocult-SM 그리고 MSB배지 배양법으로서 타액 내 Streptococcus mutans를 측정한 후 그 값을 우식경험치아수와 비교하여 상관관계를 알아보았다. Saliva-check Mutans를 이용한 방법은 Dentocult-SM과 MSB배지법과 통계학적으로 유의한 상관관계를 보였으나 (p<0.05), MSB배지법은 어린이의 우식경험치아수와 통계학적으로 유의한 결과를 나타내지 않았다 (p=0.34). Streptococcus mutans, one of the major causal agents of dental caries, is component of the dental plaque. It produces various organic acids such as lactic acid which is the end-product of glycolysis, and this leads to dental caries. A new system using species-specific monoclonal antibodies was developed to detect Streptococcus mutans in saliva. The system quickly detects salivary Streptococcus mutans in 30min and classifies the result into two levels. The purpose of this study was to investigate correlation between monoclonal antibody-based detecting system and selective medium-based detecting methods. Children's deft indices were also compared with Streptococcus mutans counts in MSB agar plate. Subjects consisted of 15 children in the age of 3 to 6 years. They were assigned to three groups: Group Ⅰ (deft index = 3), Group Ⅱ (deft index ≤ 3), Group Ⅲ (deft index ≥ 4). The results are as follows : 1. The rate of children with positive response was 13.3% and with negative response was 86.7% in the result of Saliva-check Mutans test kit. 2. There was a positive correlation between monoclonal antibody-based detecting system and selective medium-based detecting methods (p<0.05). 3. Streptococcus mutans counts in MSB agar plate were irrelevant to deft of children(p=0.34).

여성에서 Dehydroepiandrosterone sulfate와 인슐린저항성증후군의 연관성

김효정,홍은순,오지영,홍영선,성연아 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: DHEA는 안드로겐 전구체로서 연령 증가에 따라 감소한다. 남성에서 DHEA는 인슐린저항성 및 심혈관질환에 대한 보호 작용을 하는 것으로 알려져 있으나 여성에서는 인슐린저항성과 심혈관질환에 대한 DHEA의 역할은 정립되어 있지 않다. 본 연구는 여성에서 인슐린저항성과 심혈관질환에서 DHEA의 역할을 규명하고자 시행하였다. 방법: 지역사회에서 무작위 추출된 471명의 여성을 대상으로 DHEA보다 반감기가 길고 일중 변동이 적은 것으로 알려져 있는 DHEAS의 농도를 방사면역측정법으로 측정하였다. DHEAS 농도와 인슐린저항성증후군 및 이 증후군을 구성하는 인자들과의 연관성을 관찰하였다. 결과: 1. 인슐린저항성증후군 인자의 빈도는 비만 25.3%, 내당능장애 8.5%, 고혈압 21.9%, 이상지질혈증 6.2%이었으며 인슐린저항성증후군의 빈도는 16.5%이었다. 2. DHEAS는 연령(r=-0.47, p<0.001), 수축기혈압(r=-0.18, p<0.001), 이완기혈압(r=-0.10, p<0.05), 공복혈당(r=-0.10, p<0.05), 포도당부하 2시간 혈당(r=-0.12, p<0.01), 및 중성지방(r=-0.16, p<0.01)과 의미있는 음의 상관관계가 있었다. 3. DHEAS 농도를 사분위수로 나눈 후 연령을 보정한 후 인슐린 저항성증후군 구성요소의 빈도를 관찰하였을 때 DHEAS 농도 감소에 따라 고혈압의 빈도가 유의하게 증가하였다.(p<0.05). 4. 연령(p<0.0001) 및 체질량지수(p<0.05)가 DHEAS에 영향을 주는 인자로 작용하였다. 5. 연령을 보정한 후 낮은 DHEAS농도는 인슐린저항성증후군의 위험인자로 작용하지 않았다. 결론: 여성에서 혈청 DHEAS 농도는 혈압, 혈당 및 혈청 지질 농도와 음의 상관관계가 있었으며, 연령을 보정한 후 DHEAS 농도가 감소함에 따라 고혈압의 빈도가 증가하는 것으로 보아 최소한 DHEAS는 인슐린저항성증후군에 대해 위해 작용을 가지지는 않는 것으로 생각된다. 그러나 DHEAS의 인슐린저항성증후군 및 심혈관질환에 대한 보호 작용을 증명하기 위해서는 이들 대상자를 전향적으로 추적 관찰하여 인슐린저항성증후군 및 심혈관질환의 발생과 DHEAS의 관계를 규명해야 할 것이다. Background: Dehydroepiandosterone (DHEA) is an androgen precursor, and is known to be decreased by the aging process. DHEA has been known to have a protective effect on insulin resistance and cardiovascular disease in men, but remains controversial in women. The aim of this study was to elucidate the role of DHEA on insulin resistance, and the risk for cardiovascular disease, in women. Methods: We analyzed the relationship between DHEA sulfate (DHEAS), known to have a longer half-life and less diurnal variation than DHEA, and insulin resistance syndrome (IRS) in 471 non-diabetic women from an urban community diabetes prevalence study. Serum DHEAS concentrations were measured using a commercially available radioimmunoassay kit. Results: 1. the frequencies of obesity, impaired glucose tolerance, hypertension and dyslipidemia were 25.3, 8.5, 21.9 and 6.2%, respectively, and the frequency of IRS was 16.5%. 2. DHEAS was significantly inversely correlated with age (r=-0.47, p<0.001), systolic blood pressure (r=-0.18, p<0.001), diastolic blood pressure (r=-0.10, p<0.05), fasting serum glucose (r=-0.10, p<0.05), postchllenge 2 hour glucose (r=-0.12, p<0.01) and triglycerides (r=-0.16, p<0.01). 3. As serum DHEAS concentrations, by quartiles, were decreased, the age-adjusted frequency of hypertension was significantly increase (p<0.05). 4. A Multiple linear regression analysis revealed that DHEAS was significantly associated with age (p<0.0001) and BMI (p<0.05). 5. A Logistic regression analysis showed that DHEAS was not associated with IRS after adjustment for age. Conclusion: DHEAS is inversely associated with age. DHEAS has no harmful effect, and may even have a protective role, on insulin resistance syndrome. Prospective examinations of DHEAS and insulin resistance syndrome in women are needed to confirm the mechanism for the association between DHEAS and the development of cardiovascular disease (J Kor Soc Endocrinol 17:675∼684, 2002).

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

서정아,김재곤,백병주,양연미,이용희,김상훈 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).

The purpose of this study was to examine research trends in infant research published from 2000 to 2013, in order to understand overall aspects in research topics, methods, and subjects in infant research and to suggest directions for future infant research. A total of 2916 journal articles and theses/dissertations, both domestic and foreign, were selected for the analysis. The findings of this study were as follows: First, for the 14 year period, 737 domestic articles, 634 domestic theses/ dissertations, 1242 foreign articles, and 303 foreign dissertations on infant research were published, and there was a steady increase in the number of articles and theses/dissertations over the years. Second, in terms of research topics, different patterns were found between the domestic ones and the foreign ones; the topic of “education and teachers” in the domestic ones and “development” in the foreign ones occurred most frequently. Third, in terms of research methods, the domestic ones employed “survey” the most, and the foreign ones employed “experiment” the most among quantitative research methods; when analyzing the relation between methods and topics, the foreign ones showed clear matches between topics and research methods, while the domestic ones preferred “survey” regardless of the topics. Fourth, in terms of subjects/participants, “infants” were the most researched in both the domestic ones and the foreign ones, followed by “parent” and “teachers.” Among the infants, the domestic ones focused on 25~36-month olds the most, while the foreign ones focused most on 0~12-month olds. In addition, in all types of infant research, there were more single subject studies than multiple subject ones.
