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.

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.

A classification algorithm of traffic signs using a MSHMT (modified synthetic hit-miss transform) is proposed for the autonomous road vehicles(ARV's). In the case of classification of traffic signs, there are many kinds of signs with intraclass distortions and interclass similarities. The MSHMT provides a good solution with the property of distortion invariant recognition of multiple objects in noisy and cluttered scene. The proposed algorithm of traffic sign classification consists of the phase of sign detection and the phase of symbol recognition. In the phase of sign detection. structuring elements(SEs) are synthesized using only set theory to adapt to simple variations. In the phase of symbol recognition, SEs are synthesized using set theory and SDFkynthetic discriminant function) synthesis method to adapt to complex variations. Based on extensive simulations, it has been shown that the proposed algorithm is efficient for the classification of traffic signs.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.
