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.

윤정로,심재익,김택선,이성종,김영배,김학준,안국환,장재영,홍명표 대한골절학회 2002 대한골절학회지 Vol.15 No.4

쇄골 중간 1/3 부위의 골절은 치료 결과가 양호하여 보존적 치료가 원칙적으로 받아 들어지고 잇으며 불유합에 대한 빈도도 낮은 것으로 되어 있다. 그러나 최근 전위 및 단축의 정도가 심할 경우 높은 불유합의 결과와 불량한 임상 결과를 보고하고 있어 이런 예에 대해선 수술적 치료를 권장하고 있다. 저자들은 단축 및 전위의 정도와 불유합의 연관성을 알아보고자 하였다. 연구 대상 및 방법 : 1993년 2월부터 2002년 1월까지 본원에 내원 했던 성인 중간부 쇄골 골절 환자 194명 중 완전 전위를 보인 78례를 조사하여 이중 63례를 대상으로 분석하여 후 향적 연구를 시행하였다. 4개월 추시 후에도 방사성 사진상 유합 소견이 관찰되지 않으면 불유합의 유의성을 알아보고자 하였다. 결 과 : 63례 중 불유합 및 지연 유합을 소견을 보인 환자는 15(23%)례였다. 골유합을 보인 48례의 단축은 평균 8.6㎜(2㎜-17㎜)였고, 전위는 평균 9.7㎜(2-22㎜)였다 .불유합 및 지연 유합을 보였던 15례에서 단축은 평균 14.5㎜(3㎜-37㎜), 전위는 평균 17.3㎜(4-25㎜)였다. 18㎜이상 단축이 있었던 경우 불유합의 발생과는 통계학적으로 유의성을 나타내었고(Fisher's exact test, p<0.01), Chi-square test상 16㎜ 이상의 전위를 보였던 경우 불유합 발생과 통계학적으로 의미가 있었다(p<0.01). 결 론 : 쇄골 골절 특히 중간 1/3의 골절은 비교적 보존적 치료에 결과가 좋은 것으로 되어 있으나, 전위 및 단축이 심한 경우 불유합에 대한 가능성이 높이 때문에 보다 경과 관찰시 유합의 진행이 없으면 적극적인 치료를 고려해야한다. Purpose : Because the prognosis of the mid 1.3 clavicle fracture is good, the conservative treatment with a figure of 8 bandage is the gold standard and the nonunions are rare. However, recently surgical treatment is recommended when the shortening and displacement is severe because of the high nonunion rate and the poor clinical result. This study was undertaken to evaluate that the shortening and displacement at fracture site are associated with the development of nonunion. Materials and Methods : We analysed the 194 fractures of mid 1/3 clavicle in adults which had been treated conservatively from February 1993 to January 2002 and did the retrospective study. Of these, 78 cases were originally in the middle third of the clavicle and had been completely displaced. We reviewed 63 of these cases. The shortening and displacement at the fracture site was measured on the initial roentgenogram. And the analysis of the patients' chart was done for another predisposing nonunion factors. Nonunion and delayed union are considered to be present when there has been little or no progression of clinical or radiographic healing at a minimum of 4 months after injury. Results : 15 of the 63 cases had developed nonunion.. The average 8.6㎜(2㎜-17㎜) shortening and average 9.7㎜(2-22㎜) in the union patients. The average 14.5㎜(3㎜-37㎜) shortening and average 17.3㎜(4-25㎜) in the nonunion patients. We found that initial shortening ≥18㎜(Fisher's exact test, p<0.01) and initial displacement ≥ 16㎜(Chi-square test. p<0.01)at the fracture site were significantly associated with the development of nonunion. Conclusion : The conservative treatment with figure-80-bandage is the gold standard in the clavicle middle one third fracture. However, the nonunion is commonly occurs in the cases of more of severely shortened and displaced fractures. If there are no signs of callus formation and the patient complains of pain after several week, osteosynthesis should be considered.

이원종,윤정로 강릉대학교동해안지역연구소 1997 東海岸硏究 Vol.7 No.2

응고제로서 해수의 사용이 제조된 두부의 물리적 특성에 미치는 영향을 비교하였다. 해수 사용시의 두부의 수분함량은 다른 응고제 사용시보다 높았고 이것이 제조된 두부의 부드러운 조직에 영향을 끼치는 것으로 추정되었다. 또한 해수를 사용한 두부는 부드러운 가운데서도 결착성이 좋았다. 압착도를 달리하여 두부를 제조하였을 때 압착도가 증가함에 따라 두부의 수분 함량 및 수율은 감소하였고 경도는 증가하였다. 관능검사 결과 전체적인 기호도는 ??,??,?? 의 순으로 최적압착도에서의 압착을 통한 적정 경도 유지가 중요함을 알 수 있었다. 제조된 두부의 경우 경도는 수분함량이 높을수록 또 섬유질의 함량이 낮을수록 감소하였다. In this study, sea water was compared with several conventional coagulants (calcium chloride, calcium sulfate, magnesium chloride and gluconodeltalalactone) in its effect on the physical properties of tofu coagulated with it. Chodang tofu (coagulated with sea water) was highest in the moisture content and this made the texture of tofu soft. Moreover, Chodang tofu was not only soft but also cohesive. As the molding pressure was increased, the moisture content and the yield of tofu were decreased but the hardness was increased. As far as molding pressure is concerned, sensory evaluatin indicated that the overall preference of tofu was in the order of ??, ?? and ??. The hardness of Chodang tofu was lower with its higher moisture content and with lower fiber content.

교토대학 원자로 연구소의 46MeV 전자선형가속기를 사용하여 중성자 TOF 방법으로, 에너지 영역 0.003eV∼50keV의 ^161, 163Dy sample의 중성자 포획 단면적을 측정하였다. 본 실험에서 사용된 Bi_4Ge_3O_12(BGO) 섬광 검출기는 sample의 핵반응에서 나오는 즉발 포획 감마선 측정에 사용하였다. 이 검출기는 중성자 선원으로부터 거리 12.7±0.02m 위치에 12개의 블록으로 되어 있으며, sample에 포획되는 중성자 flux의 절대치를 구하기 위해 Sm(n, γ) 및 ^10B(n, αγ) 반응을 이용하였다. ^161, 163Dy에 대한 포획 단면적 측정결과는 ENDF/B-VI 결과와 비교하였다. The neutron capture cross sections of ^161, 162Dy has been measured in the energy region from 0.003eV 50keV by using the neutron time-of-flight(TOF) promptγmethod with a 46MeV electron linear accelerator at the Research Reactor Institute, Kyoto University. An assemble of twelve pieces of BGO scintillation detectors, which was placed at a distance of 12.7±0.02mm from the neutron source, was employed as a total energy absorption detector for the prompt capture gamma-ray measurement, to obtain the absolute capture cross section value. The sample of ^161, 163Dy is a form of metallic plate. An enriched boron sample was employed to monitor the neutron flux/spectrum of the TOF beam using the standard reference cross section of the ^10B(n, αγ) reaction. Previous measurements and evaluated data in ENDF/B-VI was compared with the present results.

이원종,윤정로,김은경,안규태 강릉대학교 동해안지역연구소 2000 東海岸硏究 Vol.11 No.1

추출조건 (온도, 추출시간, 용매의 농도)에 따라 당귀의 특유성분인 decursin의 함량을 측정하였으며, 산지별로 당귀를 수집하여 추출물을 제조한 후 이화학적 성질을 조사하였다. 물, ethanol, methanol, chloroform, benzene, ether등으로 추출한 결과, 당귀의 지표물질인 decursin은 물로는 잘 추출되지 않았고 고농도의 ethanol로 추출하는 것이 가장 효과적이었다. 당귀의 ethanol 추출물 제조시 ethanol의 농도는 95%, 추출온도는 60℃, 추출시간은 4시간이 가장 적합하였다. 진부지역에서 생산된 일당귀 및 일본산 당귀의 decursin 함량은 0.2-0.5%이었고, 중국산 당귀는 1.1%를 함유하였으며 진부산 토당귀는 6.2%를 함유하였다. 진부산 토당귀와 일당귀, 중국산, 일본산 당귀를 열수 추출물, ethanol 추출물을 제조한 결과, 열수 추출물은 ethanol 추출물보다 단백질과 회분을 많이 함유하였으며, ethanol 추출물은 지질을 많이 함유하였다. Chemical components and decursin contents of Angelica gigas Nakai (Korean), Angelica acutiloba Kitagawa (Korean and Japanese), and Angelica sinensis Diels (Chinese) were analyzed. Angelica gigas Nakai (Korean) contained the highest amount of decursin with 6.2%, while Angelica acutiloba Kitagawa (Korean and Japanese) contained only 0.2-0.5% decursin and Angelica sinensis Diels (Chinese) contained 1.1% decursin. Angelica gigas Nakai (Korean) was extracted under various conditions and evaluated for decursin content. The decursin content of extracts was the highest when extracted with 95% ethanol at 60℃ for 4 hours. Angelica gigas Nakai was extracted with water and 95% ethanol and physicochemical properties of extract were analyzed, The extraction yield. protein content, and ash content were high when using the water as an extraction solvent; while, crude lipid was high when using the 95% ethanol as the extraction solvent.

정용태,윤정로 順天靑巖大學 1992 論文集-順天靑巖大學 Vol.16 No.-

Microcystis aeruginosa의 증식에 미치는 중금속 첨가실험을 하여 조류증식에 미치는 중금속의 영향과 제거되는 중금속의 량을 조사하였다. 조류의 양은 건조중량법으로 중금속의 양은 원자흡광분석기로 분석하였다. 인제한실험에서 Monod type의 동력학적 해석으로 부터 μ_max=0. 6 day^-1이고 Ks=0. 06 mg/L의 값을 얻었다. 중금속이 저농도로 첨가되면 증식촉진효과를 나타냈고, 한계증식촉진농도 이상이 되면 증식저해를 나타냈다. 한계증식촉진농도는 크롬은 극미량이며, 구리와 카드뮴은 0. 2 ㎎/L이고, 코발트는 0. 4 ㎎/L이었다. Microcystis aeruginosa에 중금속을 첨가하면 증식저해는 비길항적 저해로 나타났고, 증식저해상수는 크롬은 0. 85 ㎎/L, 구리는 3. 23 ㎎/L, 코발트는 10. 53 ㎎/L를 나타냈다. 첨가된 중금속은 구리의 경우 5-10%정도 제거가 되고, 크롬이나 코발트는 거의 제거되지 않았다. The effects of heavy metals on Microcystis aeruginosa and quantity of heavy metals removed were experimentally investigate with adding heavy metals to CB media. The algal mass was determied by suspeded solids deried at 103-105℃ ad heavey metals determined by Atomic Absorption Spectrometry. Under the Phosphate-limiting culture condition, the kinetics coefficient of Monod equation, μ_max and Ks, calculated form the least-square method, were 0. 6 day^-1 and 0. 06 ㎎-P/L. The growth of Microcystis aeruginosa was accelerated at low concentration of heavy metal but inhibited above the critical growth-accelerating concentration. The critical growth-accelerating concentration was on the very low level;Cu and Cd was about 0. 2 ㎎/L and Co was 0. 4 ㎎/L respectively. When adding heavy metals to the culture media of Microcystis aeruginosa, the type of growth inhibition was turned out by noncompectitive-inhibition. The growth inhibition consatnat of Cr, Cu and Co was 0. 85 ㎎/L, 3. 23 ㎎/L and 10. 05 ㎎/L respectively. Cr and Co added to CB media was little removed but Cu removed at 5-10%.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.
