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.

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 SDF(synthetic 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.

The purpose of this study is to investigate the differences between the competitive state anxiety with 3 sub-categories and the competitive trait anxiety on gender and weight classification. The study empolyed 523 Judo players in high schools. The results of this study are as follow: 1. The congnitive state anxiety(p<.01) and state self-confidence(p<.01) in competitive state anxiety showed significant difference on gender. Competitive trait anxiety also showed significant difference(p<.05) on gender. 2. Differences in competitive anxietyaccording on weight classification was revealed. Significant difference in sometic state anxiety and cognitive state anxiety were showed on overall weight classification. State self-confidence showed significant difference between middle weight and heavy weight and between light and heavy weight. 3. Interaction effect for gender and weight clasiffication was revealed in sometic state anxiety.

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.

Langerhans Cell Histiocytosis는 Langerhans Cell 의 비정상적인 증식을 특징으로 하는 질환이다. 임상적 양상은 단독 골병소에서부터 여러 장기를 침범하여 치명적인 경우까지 매우 다양하게 나타나며, 나이가 어릴수록, 침범된 장기의 수가 많을수록 예후는 좋지 않다. 악골의 경우는 전체 Langerhans Cell Histiocytosis 환자의 10~20%에서 나타나며, 주로 초기에 이환된다. 본 환아는 만 3세 때 하악골 전반에 걸친 동통으로 본 치과병원에 내원하여 조직학적 검사를 통해 Langerhans Cell Histiocytosis임을 확진 받은후 소아과에 의뢰되어 화학요법에 의해 치료되었다. 재발의 가증성이 있어 현재 주기적 검사중이며, 하악 좌측 제2소구치배의 상실로 인해 향후 교정치료 및 보철치료가 필요하리라 사료된다. 본 증례는 치과병원에서 Langerhans Cell Histiocytosis임을 확진한 후 조기치료를 시행해 주어 양호한 결과를 얻었기에 보고하는 바이다. Langerhans Cell Histiocytosis(LCH) is characterized by proliferation of Langerhans cells. The clinical manifestation varies from solitary bone lesion to multi-system, life threatening disorder. The younger the patient is and the more system is involved, the worse the prognosis is. The jaw is involved 10~20 percent of all LCH and it is involved usually in early stage of LCH. In this case the patient is three years old girl who suffered from pain of whole mandibular body and histological examination confirmed the dignosis LCH. She is referred to pediatrics and managed with combined chemotherapy. Due to the possibility of recurrence, we follow up the girl and she need orthodontic and prosthodontic treatment in the future because of the loss of lower left 2nd premolar. We report this case because early recognized LCH in dental hospital result in good prognosis.

In this paper, we have discussed on the characteristics and modeling of machined geometry which was established for the case of round shape machining, also the effects of externally machined profile are analyzed and its modeling realia-biliy was verified by the experiments of roundness testing, especially in lathe operation. In this study, we established a harmonic geometric model with the parameter harmonic function. In general, we can calculate the theoretical roundness profile with an arbitrary multilobe parameter. But in real experiments, only 2-5 lobe profile was frequently measured. the most frequently measured ones are 3 and 5 lobe profile in experiments. With these results, we can predict that these results may be applied to round shape machining such as turning, drilling, boring, ball screw and cylindrical grinding operation in bearing and shaft making operation with the same method. In this study, simulation and experimental work were performed to show the profile behaviors. we can apply these new modeling methods in real process for the predic-tion of part profile behaviors machined such as in round shape machining operation.
