The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

윤상옥,박정근,윤종호,이학현 강원대학교 석재복합신소재제품연구센터 2001 석재연 논문집 Vol.6 No.-

새로운 상감도자기 기법을 이용한 특산품은 개발하기 위하여 지르코니아와 백토 및 황토계 소지에 대한 선 수축과 색의 변화를 조사하였다. 지르코니아계는 1350℃ 소결에서 23%정도의 선수축율을 나타내고 첨가량은 0.5wt% 이내가 적당하며, Co3O4는 청색, NiO는 녹색, Fe2O3는 갈색 그리고 Mn3O4는 검정색으로 변하였다. 백토계는 1250℃ 소결에서 13%정도의 선수축율을 나타내고 첨가량은 1wt%이내가 적당하며, NiO는 갈색, Co3O4는 녹색, TiO2는 아이보리색으로 변화 하였다. 황토계는 1250℃ 소결에서 12.5%정도의 선수축율을 나타내며, TiO2는 노란색, 그리고 복합첨가의 경우 검정색으로 변화하였다. 첨가된 전이금속산화물은 제2상의 화합물을 형성하여 분산되어 존재함으로써 발색시키는 것으로 판단된다. 상감도자기 시작품은 색채가 우아하고 질감이 좋아 특산품으로 활용가능성이 매우 높은 것으로 판단된다. Variation of sintered color and linear shrinkage in zirconia, white clay and yellow clay systems have been investigated with various transition metal oxide additives to develop special products using new inlaid porcelain method. Zirconia systems sintered at 1350℃ show 23% of linear shrinkages and their additives are suitable to add up to 0.5wt%, and the color of their specimens changes from white to blue for Co3O4, green for NiO, brown for Fe2O3 and black for Mn3O4, respectively. White clay systems sintered at 1250℃ appear about 13% of linear shrinkages and their additives are suitable to add up to 1wt%, and the color of their specimens changes form white to brown for NiO, to blue for Co3O4, green for Cr2O3 and ivory for TiO2, repedtively. Yellow clay systems sintered at 1250℃ show about 12.5% of linear shrinkages and the color of their specimens changes from red to yellow for TiO2 and black for complex compounds, respectively. It could be explained due to the formation of the second phase compounds by added transition metal oxides with basic composition and the dispersion of their second phase particles in sintered bodies.

Chlamydia pneumoniae infections, known to be very prevalent in many countries, are not reported in Korea to the best of our knowelege. Prevalence of antibodies against C. pneumoniae was determined by the micro-immunofluorescence test. The proportion of sera with antibody titers of ≥16,tested by polyvalent conjugate of IgG, IgM, and IgA (poly-Ig) were blood donor 76.8%, blood chemistry-tested patients 58.0% and Mycoplasma Pneumoniae antibody-tested patients 22.0%. The positive rates by age groups were ≤years 13.5%, 10-19 years 66.7% and over all 49.6%. Only three sera showed IgM antibody titer of ≥, which became negative after absorption with RF-absorbent. Poly-Ig against C. trachomatis was less prevalent and that against Legionella pneumophila rare. None of the sera at 1:8 dilution were positive for the poly-Ig against Coxiella burnetii. It is concluded that the poly-Ig antibody against C. pneumoniae are highly prevalent in the sera of Koreans suggesting the existance of the infection, and for the diagnosis of the infection, the same interpretation criteria of the MIF titer, which is used in other countries, can also be applied in Korea.

성상진,문윤식,김정국,정현성 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.2

악안면 기형과 부정 교합의 성공적인 교정 치료를 위하여 안모의 3차원적인 평가가 필수적이지만 교정의사는 주로 측모두부방사선사진에 기초한 진단 및 치료계획에 익숙하다. 이는 정모두부방사선사진에 관한 계측치, 악골의 폭경 성장에 관한 지식과 임상적 의의에 대하여 관심이 부족한 때문으로 생각된다. 본 연구에서는 골격성 I 급 부정교합으로 진단된 6세에서 16세 사이의 남자 130명과 여자 171명을 대상으로 정모두부방사선사진 상의 두개골 및 상하악골의 폭경을 계측하여, 연령과 경추골 발육지표(CVMI)에 따른 변화 양상을 알아보았다. 다항 회귀모형(polynominal regression models)과 변수선택법(method of variable selection)을 이용하여 적합한 회귀모형(regresslon model)을 각 성별에서 선택하고 이를 이용하여 연령에 따른 각 계측치의 평균 및 개별 계측치(individual measurement)의 70% 신뢰구간(confidence interval)을 추정하여 그래프로 작성하였으며, 다음과 같은 결과를 얻었다. 1.모든 폭경 계측치는 나이 또는 CVMI의 증가에 따라 점차 증가하였으며,6세부터 16세까지의 총변화량은 상악골 폭경보다는 하악골 폭경이 그리고 여자보다는 남자에서 더 많은 경향을 나타내었다. 2.Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio는 연령과 CVMI에 따른 남녀간의 유의차가 없었다. 3.회귀모형을 이용하여 나이에 따른 남녀 계측치의 평균 및 신뢰구간을 70%로 추정하여 상악골폭경,하악골 폭경, Mx-Mn difference, Mx/Mn ratio에 대한 그래프를 얻었다. 4.한국인의 상하악골 폭경은 성장기 동안 서양인에 비하여 큰 경향을 나타내었다. 본 연구의 결과를 성장기 부정교합 환자의 폭경 성장 평가와 폭경 부조화의 진단에 이용한다면 치아 석고모형 만을 이용하는 한계를 적절히 보완할 수 있다고 생각된다 Three dimensional analysis of malocclusion and craniofacial deformation is essential for the successful orthodontic treatment. But the orthodontists are not familiar with diagnosis and treatment plane based on lateral cephalometric analysis. Since orthodontists do not posses a sufficient knowledge in standard value of posteroanterior cephalometric analysis and of clinical importance for transverse jaw growth. In this study male(n=130) and female(n=171) aged from 6 to 16 and diagnosed as Class I malocclusion were selected to analysis width of cranium, maxilla and mandible on the posteroanterior cephalogram. The changes as a function of chronologic age and cervical vertebrae maturity index(CVMI) were examined. The proper regression model was selected by sex with polynominal regression models and method of variable selection. Mean of each measurements and 70% confidence interval of individual measurement according to age was assesed and a graphs were made. Results are as follows : 1.All the measurements for the width are gradually inclesed as increase in chronologic age and CVMI. From the total amount of change between age 6 and 16, there is a tendency that mandibular width is broader than maxillary width and the width of male is broader than female. 2.There is no statistically significant sexual difference in Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio according to age and CVMI. 3.Mean of each measurement and 70% confidence interval of individual measurement according to age and sex were assessed and graphs were made for maxillary width, mandibular width, Mx-Mn difference, Mx/Mn ratio. 4.The width of maxilla and mandible in Korean children are broader than Western children during growth period.
