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.

민경호,박효상,배용철,성재현 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.3

이 연구의 목적은 말초조직에 유해 자극을 가하였을 때 중추 신경계내 이차 신경 세포체내에 발현되어 Neuronal marker로 사용되고 있는 c-fos를 사용한 면역 조직화학법으로 치아이동시 동반되는 동통의 투사경로의 이해에 도움을 주고자하는 것이다. 생후 9 주령의 210gm내외의 Sprague-Dawley계 웅성 백서 21마리를 교정력을 가하지 않고 마취만을 시행한 정상대조군과 교정력 적용 시간 경과에 따라 1시간, 3시간, 6시간, 12시간, 1일, 3일군으로 나누어 각 해당 시간동안 상악 우측 제1대구치와 상악 우측 측절사이에 Ni-Ti coil spring을 결찰하여 30gm내외의 지속적인 교정력을 가한 후 희생시켰다. 희생시킨 백서의 뇌간을 적출하여 토끼의 항체를 이용하여 면역화학 염색을 시행하였다. 삼차신경 감각핵군내 부위에 따른 c-fos 면역 반응 세포를 측정하여 교정력 적용 시간 경과에 따른 변화를 관찰하였다. · c-fos면역 반응 세포의 배측에서의 분포는 자극측 중위핵과 미측핵의 이행부위에서 시작하여 제1경추 척수 후각에까지 이어졌는데 가장 많은 분포를 보인 곳은 미측핵의 문측 부위였다. 그리고 주로 I층 과 II층에서 관찰되었다. · 복측에서의 c-fos 면역 반응 세포의 분포는 자극측 중위핵의 미측 부위에서 시작하여 미측핵의 중간부위에 까지 이어졌다. · 교정력 적용 3,6시간군에서 c-fos면역 반응 세포가 가장 많이 관찰 되었으며 12시간군에서 감소되기 시작하여 1일, 3일군에서는 현저히 감소 하였다. 위로 미루어 볼 때 지속적인 교정력에 의한 동통은 중위핵과 미측핵의 이행부위, 미측핵, 제1경추 척수후각에서 매개되는 것으로 생각된다. The c-fos is known as neuronal marker of second neurons which is activated by noxious peripheral stimulation. To investigate the changes of c-fos expression in the trigeminal nucleus complex during tooth movement, immunohistochemical study was performed. Experimental rats(9 weeks old, 210 gm, 21 rats) were divided into seven groups(normal, 1 hour group, 3 hour group, 6 hour group, 12 hour group, 1 day group, 3 day group). Rats in the normal group were anesthesized without orthodontic force. Rats in the experimental groups were applied orthodontic force (approximately 30 gm) to upper right maxillary molar. Frozen sections of brain stem were immunostained using rabbit antisera. The change of c-fos expression were observed with respect to rostrocaudal distribution, laminar organization, and duration of orthodontic force application. The study results were as follows. · The c-fos nuclei in the dorsal part were observed from ipsilateral transition zone of subnucleus interpolaris and subnucleus caudalis to C1 cervical dorsal horn rostrocaudally. The maixmal peak point was the rostral part of subnucleus caudalis. The greatest proportion of c-fos cells were located within lamina and I and II. · The c-fos nuclei in the dorsal part were observed from the most caudal part of subnuleus interpolaris to the middle part of the subnucleus caudalis. · The number of c-fos immunoreactive dot increased at 1 hour group, reached its maximum at the 3 and 6 hour groups, and showed a decreasing trend after 12 hours. These resutls imply that nociceptive stimulation caused by continuous orthodontic force might be modulated by transition zone of subnucleus interpolaris and subnucleus caudalis, subnucleus caudalis, C1 spinal dorsal horn.

배창휴,Abe, Tomoko,민경수,김동철,정재성,이춘환,임용표,이효연 충남대학교 생물공학연구소 1999 생물공학연구지 Vol.7 No.-

중이온 빔을 이용한 방사선 돌연변이의 기초자료를 얻고자 담배의 수분·수정 직후의 원배에 100 Gy의 중이온빔을 조사하여 M_1세대의 종자를 얻었다. NaCI 2.0과 2.5%를 포함된 MS배지에 M_1 세대의 종자를 파종하여 17개통의 NaCI 저항성 식물체를 선발하였다. 저항성 식물체는 BY-4품종에 ^14N빔을 조사한 처리구에서만 관찰되었다. M_1 세대의 저항성 식물체의 경우 영양생장기간 중에는 외형적 변이가 관찰되지 않았으나 생식생장기의 화기에 있어서는 다양한 변이가 관찰되었다. 특히 암술 수술의 길이의 변화, 꽃잎의 변화, 불완전 화분립, 줄기당 꽃의 착생수 감소 등의 변이가 발생하였다. M_1 세대에서 17개의 NaCI저항성 계통 중에서 8계통은 M_2 세대에도 저항성형질이 발현되었고, 또한 M_2 세대의 3계통은 Mannitol이 포함된 배지에서 저항성을 보여주었다. Tobacco proembryos were irradiated with 100 Gy of heavy-ion beams (^14N, ^20Ne : 135 Mev/u) after 24 to 96 hours of pollination as a mutagen and screened M_1 generation for morphological mutants and salt-tolerant plants. Morphological and physilolgical characteristics of the salt-tolerant plants derived from the irradiated proembryo are discussed in this report. Mutants irradiated porembryos with the beams after pollination produced various kinds of morphological variation. A total of 17 salt-tolerant plants were selected from tobacco cultivar (BY-4) by treatment with ^14N beam. Shapes of filament and pollen grain of most salt-tolerant plants were abnormal compared with non-irradiated wild type, and seeds weight and fertility obviously decreased. The germination rates of the several M_2 lines on the saline and the mannitol condition were higher than that of wild type.

Covariates included were age, gender, education, housing, Past occupation, current employment, and depression. Of 879 without insomnia at baseline, 651 (74%) were followed 2 years later, and incident insomnia was evaluated. Results : Prevalent insomnia was significantly associated with 10 of 11 physical disorders. Incident insomnia was associated with 2 physical disorders : eyesight problems and hearing difficulty. Both prevalent and incident insomnia were significantly associated with increased number of physical disorders. Conclusion : Certain physical disorders were comorbid and precipitating factors of insomnia in elders.

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.

치근 천공 치료 재료의 생체친화성의 비교

강민경,배인호,고정태,황윤찬,황인남,오원만 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.3

This study was carried out in order to determine in vitro biocompatibility of white mineral trioxide aggregate (MTA), and to compare it with that of the commonly used materials, i. e. calcium hydroxide liner(Dycal), glass ionomer cement (GIC), and Portland cement which has a similar composition of MTA. To assess the biocompatibility of each material, cytotoxicity was examined using MG-63 cells. The degree of cytotoxicity was evaluated by scanning electron microscopy (SEM) and a colorimetric method, based on reduction of the tetrazolium salt 2,3 bis {2methoxy 4nitro 5〔(sulfenylamino) carbonyl〕2H tetrazolium hydroxide} (XTT) assay. The results of SEM revealed the cells in contact with GIC, MTA, and Portland cement at 1 and 3 days were apparently healthy. In contrast, cells in the presence of Dycal appeared rounded and detached. In XTT assay, the cellular activities of the cells incubated with all the test materials except Dycal were similar, which corresponded with the SEM observation. The present study supports the view that MTA is a very biocompatible root perforation repair material. It also suggests that cellular response of Portland cement and GIC are very similar to that of MTA. 이번 연구는 치근 천공의 치료 재료인 white mineral trioxide aggregate (MTA)를 흔히 사용되는 calcium hydroxideliner(Dycal^(R), glass ionomer cement (GIC), 그리고 MTA와 유사한 성분을 가진 Portland cement와 세포독성 실험으로 생체 친화성을 평가하는 것이다. 세포독성의 정도는 MG-63 세포를 이용해 주사전자 현미경적 관찰과 수용성 tetrazolium salt를 이용한 흡광도를 측정 (XTT assay)하여 평가하였다. SEM 관찰에서, 1일과 3일째 모두에서 GIC와 MTA, Portland cement표면에서는 잘 부착된 세포를 보여주었다. 반면에, Dycal 표면의 세포들은 둥글고 부착되지 않은 양상을 보여주었다. XTT assay에서는 Dycal을 제외한 모든 재료에서 유사하게 높은 세포 활성도를 보여주었으며, 이는 SEM 관찰 소견과 일치하였다. 이번 연구는 MTA가 생체친화적인 재료라는 견해를 뒷받침한다. 또한 Portland cement와 GIC에서도 MTA와 유사한 세포반응을 보여주었다.

The purpose of this study was to identify the effect of shout-term oral creatine administration of maximum strength and body composition. For this purpose, specialists in yudo and undergraduates in 'Y' University were selected as the subjects of this study and 5 persons were each randomly assigned to the group of training plus creatine, to the group of only training and to the group of only creatine administration. They were asked to ingest 20g of creatine with ionized beverage and water after breakfast, lunch and supper and before bedtime(5g x 4 times) everyday for 6 days. They was asked to conduct weight training three time a week, and sports events included bench press, leg extension, leg curl, arm curl, shoulder press and the like. The repeated them at the workload of 70∼80% of I-RM and conducted each motion in three sets. To measure muscular strength as the variable to be tested, an attempt was made to measure bench press I-RM, leg extension I-RM, leg curl I-RM, arm cur I-RM, shoulder press I-RM before and after training. An attempt was made to determine such factors related to body compostion as weight, body fat amount and body fat ratio using the Inbody 3.0 Body Compostion Analyzer. Creatine analysis was conduct through creatine in urine by using the biochemical analyzer(Model-Ha TACHI 747/737, HITACHI CO. Japen). Repeated two-way ANOVA was used to analyze data. Hypotheses were tested at the significance level of d=.05. As a result, the following results were obtained: 1. It was found that both of the groups showed a significant defference in bench press, leg extension, leg curl, arm curl, shoulder press, incline bench press, should machine, sit-up I-RMs before and after participation in short-run weight training(p<.05). But there was no difference in them between groups. And it was found that there was no interaction before and after creatine administration and one-week weight training. (p>.05). 2. It was found that there was no signigicant variation in body composition(body fat amount changes and body fat ratio changes) before and after shout-run weight training(p>.05). And it was found that there was no interaction before and after creatine administration and one-week weight training(p>.05). 3. It was found that there was no significant variation in the urinalysis before and after short-run weight training(p<.05). And it was found that there was no interaction before and after creative administration and one-week weight training (p>.05).
