Min-Kyung Kim,Byung Joon Ko,E-Yeon Kim,Byoung-Duck Han,조경환 대한가정의학회 2015 Korean Journal of Family Medicine Vol.36 No.6

Background: Fast eating or overeating can induce gastrointestinal diseases such as gastritis. However, the association between gastritis and speed of eating is unclear. The aim of this study was to determine whether eating speed is associated with increased risk of endoscopic erosive gastritis (EEG). Methods: We carried out a cross-sectional study involving 10,893 adults who underwent a general health checkup between 2007 and 2009. Two groups, EEG patients and EEG-free patients, were compared by using the t-test and the chi-square test. Multiple logistic regression analyses were performed to investigate the association between eating speed and EEG. Results: The group with EEG had a higher proportion of males, average age, body mass index, and percentages of current smokers and risky drinkers than those without EEG. After adjusting for anthropometric, social, and endoscopic parameters, the group with the highest eating speed (<5 min/meal) had 1.7 times higher risk for EEG than the group with the lowest eating speed (≥15 min/meal) (odds ratio, 1.71; 95% confidence interval, 1.20–2.45). Conclusion: High eating speed is an independent risk factor for EEG. Our results indicate the need for further studies to clarify the role of eating speed in gastritis.

Purpose: The purpose of this descriptive study was conducted to investigate the health condition and satisfaction for health examination of students in elementary school. Method: The subjects for this study were 113 students, from an elementary school in W, Kyung-Buk Province. The health condition and satisfaction Questionnaire made by Kyung-Buk Education Office(2007) and modified by authors of this study were used to measure health condition and satisfaction. The data were collected from Dec. 21 to Dec. 13, 2009 using questionnaire with self reported and records of the school health. Data was analysed by x 2-test, independent t-test and ANOVA with SPSS WIN 17.0. Result: There were no statistically significant differences in the reported satisfaction scores of elementary school children regarding health examinations either by gender (male: 40.13 ± 3.90, female: 39.95 ± 4.50)or economic conditions (low: 41.00 ± 2.3, upper: 40.53 ± 4.9, middle: 39.66 ± 4.1). Conclusion: The findings in this study did not support differences in satisfaction scores either by gender or level of income relative to health examination. Future research may utilize a qualitative approach to explore differences among school.

이영우,고경수,고재준,박경수,김원배,한은경,김성연,조보연,이홍규,고창순,민현기 한국지질학회 1991 韓國脂質學會誌 Vol.1 No.1

Since the changes of Na^+-Li^+ countertransport (SLC) Vmax in essential hypertension have been reported. it has been known that hyperlipidemia could affect SLC independently of blood pressure. To reveal the relation between SLC Vmax and RBC membrane fatty acid conposition in the hypertensive patients, we divided patients into two groups according to their levels of SLC Vmax of erythrocytes(elevated SLC Vmax: n=4, normal SLC Vamx: n=6). The results were as follows: 1) There was no difference in body mate index, waist-hip ratio, blood pressure, serum cholesterol level between two groups. Triglyceride were higher in elevated group (278.0±180.0 ㎎/㎗) than normal group (124.3±60.7 ㎎/㎗) but there was no statistical significance. HDL-cholesterol levels were significantly lower in elevated group (32.0±3.6 vs. 44.8±8.9 ㎎/㎗) and free fatty acid concentrations, intracellular (RBC) Na^+ concentrations were similar between two groups. 2) The results of oral glucose tolerance test showed no differences in the glucose and insulin area, however the incremental insulin areas of elevated group (108.8±31.3, μU. min/㎖×10²) were significantly higher compared with those of normal group (56.3±20.7 μU. min/㎖×10²). 3) In the elevated group, palmitic acid proportions of erythrocytes (22.1±0.7%) were higher than those of normal group (20.1±0.7%) and SLC Vmax showed significant correlation (r=0.81, p$lt;0.01) with palmitic acid proportion. These results suggest that the abnormal lipid metabolism may change the RBC Na^+ transport system through the alterations of RBC membrane fatty acid composition.

본 연구에서는 가압가열 및 microwave 처리가 gliadin의 항원성에 미치는 영향을 살펴보기 위해 강력분에 가압가열과 microwave를 단독 또는 병행으로 처리하여 Ci-ELISA, SDS-PAGE 및 immunoblotting을 실시하였다. 가압가열 처리의 경우 시간이 길어질수록 IgG와의 결합력이 감소하였으며, 특히 50분 처리구에서 약 87%로 가장 낮은 결합력을 보였다. 또한 SDS-PAGE와 immunoblotting 결과에서도 무처리구에서 강하게 보였던 gliadin band가 가압가열처리에 의해 거의 소실되고 항체와 반응하지 않았다. 가압가열 및 microwave를 병행 처리 시도 마찬가지로 gliadin의 결합력이 감소하였으며, 처리구 중 가압가열 50분, microwave 5분 처리구에서 약 93%로 가장 낮은 결합력을 보였다. 반면 microwave를 단독으로 처리한 경우에는 일부 단백질의 변화는 관찰되었으나, 항원성 감소에는 효과가 없음을 확인하여 단백질 변화가 항원성에는 큰 효과를 준 것 같지 않다. 이상의 결과를 통해 가압가열 단독 처리 및 가압가열 및 microwave의 병행처리 시 gliadin의 항원성이 감소함을 확인하였다. This study was conducted to evaluate the effects of physical treatments on the antigenicity of gliadin in strong wheat flour. Strong wheat flour was treated with an autoclave (5, 10, 30, 50 min), a microwave (1, 5, 10 min), or both (10, 30, 50 min/ 5, 10 min), followed by SDS-PAGE, immunoblotting, and Ci-ELISA using anti-gliadin IgG. The results indicated that the binding ability of IgG to gliadin in strong wheat flour slightly decreased after autoclaving or autoclaving/microwaving. In particular, the binding ability was reduced to about 87% after autoclaving for 50 min and to 89% after autoclaving/microwaving (50/5 min). In addition, gliadin bands in the 50 min autoclaved group disappeared in both SDS-PAGE and immunoblotting. On the other hand, the antigenicity of gliadin was unaffected by microwaving alone. In conclusion, the results of this study suggest that autoclaving may reduce the antigenicity of gliadin in strong wheat flour.

Mental illness such as schizophrenia, bipolar disorder and depression have shown high prevalence of obesity. According to the previous studies, nutrition education has therapeutic effects on patients, however mentally ill patients rarely have opportunities of long term nutrition education. In this study, nutrition education based on the social cognitive theory was conducted. Patients with mental illness received education program once a month during 18 months in a day hospital. Fifteen patients were included and divided into two groups according to the attendance rate. Results showed that the group attended the education more than 10 times showed weight loss, while the group less than 10 times showed weight gain. Five long-term hospitalized patients gained weight during one year prior to the nutrition education, but showed weight loss during one year with the nutrition education. Regardless of the number of attendance, the group of BMI≥30kg/m2 showed weight loss. Although this study has several limitations and did not obtain a statistically significant results, it confirmed the necessity of providing clinical nutrition services including nutrition education for mentally ill patients.

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.

농촌지역 초등학생의 인지된 가족환경 수준에 따른 건강 행위 실천 비교

박경민,배연숙 대한보건협회 1998 대한보건연구 Vol.24 No.2

본 연구는 농촌 초등학생의 인지된 가족환경 수준에 따른 건강행위 실천을 비교 분석하여 아동의 자기 건강관리 능력 향상을 위해, 양호교사가 가족환경과 연계한 보건교육을 실시하도록 하는데 기초자료를 제시하고자 한다. 경북지역에 소재 하는 13개군 241개 초등학교를 12학급 이하인 50개 초등학교에서 17개 초등학교를 다단계 표출법으로 표출하여 6학년 전수인 583명이 대상자로 선정되었다. 자료수집은 설문지에 의해 1998년 2월 2일에서 2월 20일까지 가족환경과 건강행위 실천을 조사하였다. 연구 도구로 가족환경은 Moos(1974)가 제작한 Family Environment Scale 중 R Form을 박(1992)이 수정한 것이고(Cronbach's Alpha=0.80), 건강행위는 WHO 유럽지역 Health behavior in school-aged children(Aaro et al., 1986)에서 이용한 설문도구와 서태평양 지역의 건강증진위원회에서 개발한 설문지를 정영숙과 문영희(1996)가 수정 보완한 것을 사용하여 x^2-test, t-test, Odds Ratlo, 95% Confidence Interval로 분석한 결과 다음과 같은 결론을 얻었다. 인지된 가족환경 수준별 건강행위 실천에 대한 Odds Ratio에서, 식사관련 행위는 '아침식사' 여부(p=0.000), '3회/일식사' 여부(p=0.011), '영양제 복용'(p=0.043), 사고 예방 관련 행위는 '자동차 승차시 안전벨트 항상 착용' 여부(p=0,000), '흡연상태'(p=0.018), 개인 위생관련 행위는 '식사 전 손씻기'(p=0.000), '귀가 후 손씻기'(p=0.000) '취침 전 양치질'(p=0,000), 양치질 빈도'(p=0.000), '목욕 빈도'(p=0.000), '끓인 물 섭취'(p=0.000), 운동 관련 행위는 '같은 또래 친구들에 비하여 운동 능력의 평가'(p=0.000), 환경 관련 행위는 '가정에서 쓰레기 분리 수거'(p=0.000), '학교에서 쓰레기 분리 수거'(p=0.000)가 인지된 가족환경 수준이 낮은군에 비해 높은군의 초등학생이 바람직한 건강행위를 형성하는 것으로 나타나 유의한 차이를 보였다. 이상의 연구 결과에서 보면, 가족환경은 질병을 예방하고 건강을 유지·증진시키는 초등학생의 건강행위 실천에 지대한 영향을 미치므로, 학생들의 바람직한 건강행위를 위한 보건 교육시에도 반드시 고려되어져야 한다(김 등 1997). 그러므로 인지된 가족환경 수준이 낮은군의 초등학생을 위하여 올바른 식습관 형성, 사고 예방 관련 고육, 흡연 예방(약물 오·남용 포함). 개인 위생 실천, 지속적인 운동 프로그램, 환경 보전을 강조하는 보건교육 프로그램은 가족환경을 고려한 개발이 필요하고, 양호교사는 가족환경을 반드시 사정하여 건강행위 실천에 관한 보건 교육을 실시하여 학교 보건 교육의 목표인 아동의 자기 건강 관리 능력 향상(김 및 윤 1995)을 도모하는 적극적인 건강증신 전략자로서 양호교사의 역할 수행이 요구된다. This research intended to survey health-related behavior of the students by perceived level of family environment in rural elementary schools, analyze those factors comparatively, and use the result as the basic material for a school health teacher to teach health education connected with family environment. It also intended to improve pupil's self-abilities of health care. The subjects involve 583 students of rural elementary schools, who are selected by means of multi-stage probability sampling. Using the questionnaires, I collected data on family environment, health behaviors for 19 days, Feb. 2nd, 1998 through Feb. 20th, 1998. R-from of Family Environment Scale(Moos, 1974) is used as the instrument of family environment(Cronbach's Alpha=0.80), and questionnaires of Health Behavior in School-aged children used in WHO Europe area and the ones developed by Health Promotion Committee of the Western Pacific area(adapted by Jong Young-suk and Moon Young-hee(1996)), as the instrument of health behavior. Next step, I used them to get x^2-test, t-test. Odds Ratio, 95% Confidence Interval. Referring to the Odds Ratio of the health related behavior of the students by perceived level of family environment it was found that, higher group children in the level set up more desirable behavior than lower group children in having breakfast(p=0.000), having three meals a day(p=0.011), and taking vitamin compounds(p=0.043) as meal-related behavior, wearing safety belts(p=0.000) as accident prevention-related behavior, smoking(p=0.015), washing hands after meals(p=0.000), washing hands after home-coming(p=0.000), brushing teeth before sleeping(p=0.000), the frequency of brushing teeth more than once a day(p=0.000), the frequency of bathing(p=0.000) and intaking boiled water(p=0.000) as individual hygiene-related behavior, the estimation of physical-exercise ability compared with their peers(p=0.000) as exercise-related behavior, collecting garbage at home(p=0.000) and in the school(p=0.000) as environment-related behavior, which led to significant difference. Considering the results referred above, we could recognize that there were significant differences in health related behaviors by perceived level of family environment of rural children. These results also made us some suggestions for the coming health education. What I would like to suggest for the health program of elementary school is that, we, school health teachers, should play an active role to recognize the need and importance of health education, and incorporate them into the real school to improve children's self-abilities of health management.

The Relationship between the Salivary IgA against Ag I/II of S.mutans and Dental Caries Experience among Children and Adults

임수민,김재곤,백병주,양연미,김수경,이경열 大韓小兒齒科學會 2008 大韓小兒齒科學會誌 Vol.35 No.4

치아 우식증은 감염성 질환의 하나로 치아우식의 원인균은 Streptococcus mutans(S. mutansJ와 같은 mutans stepto-cocci로 알려져 있다. S. mutans가 치면에 접착하여 군집을 형성하는 능력은 균독성에 중요한 역할을 하는데. Agl/IT와 같은 세포 표면의 섬유성 단백질을 매개로 한다. Secretory 1gA는 타액이나 누 · 비액, 초유, 그리고 폐나 소화기관의 분비액에서 선택적으로 다량 발견되는데 타액에서 se cretory 19A는 S. mutans의 대사활동을 억제하고 치면으로의 부착을 방해한다. 이전의 몇몇 연구에서 S. mutans에 특이적인 타액 내 IgA와 우식경험도는 역상관관계를 보인다고 발표하였다. 그러나 다른 연구에서 통계적 유의성이 없다고 보고하기도 하였다. 본 연구의 목적은 소아 성인의 치아우식증과 S. mutans의 Ag I/II에 특이적인 타액 내 IgA와의 관계를 알가위한 것이다. 이를 위해 소아(평균6세) 28명, 성인(20-30세) 18명을 대상으로 Group I(deft index ≤ 3). Group II (deft index ≥ 4), Group III (DMFT index ≤ 3), Group IV (DMFT index ≥ 4)로 분류하였다. 그리고 caries resistant group(CR group, deft or DMFT index ≤ 3)과 caries susceptible group(CS group. deft or DMFT index ≥ 4)으로 분류하였다. S. mutans 수와 우식 경험도 간에는 통계적으로 유의 한 상관관계를 나타냈다. Agl/II 특이 salivary IgA titer는 Group III 이 Group II 보다 통계적으로 유의하게 더 컸으며, CR group이 CS group보다 유의하게 크게 나타났다. AgI/II of Streptococcus muiens(S. mutens) is an important virulence factor that contributes to the pathogenesis of S. mutans-induced dental caries. In oral cavity, salivary IgA antibodies act as safeguards against enormous challenges from oral bacteria. IgA antibodies inhibit adherence of cariogenic microorganisms to hard surfaces. Analysis of salivary IgA against AgI/II can be very useful diagnostic and powerful communication tools to the dental caries The purpose of this study was to investigate correlation between salivary AgI/II specific IgA and incidence of dental caries among children and young adults. Subjects consisted of 28 children and 18 adults. They were as￢signed to four groups: Group I (deft index ≤ 3), Group lI (deft index ≥ 4), Group Ill (DMFT index ≤ 3), Group IV (DMFT index ≥ 4) and they was divided two groups into caries resistant group and caries susceptible group. The study group were examined caries activity and their salivary IgA was evaluated by enzyme-linked immunosorbent assay. The results are as follows : 1. There was a positive correlation between the number of S. mutans and caries activity. 2.The titer of salivary IgA against the AgI/II was significantly higher in caries resistant group than caries susceptible group(p<0.01). 3. The titer of salivary IgA against the AgI/II in Group Ill was significantly higher than Group II (p<0.05).
