觸媒를 使用한 木材의 直接液化에 關한 硏究

陳恒敎 충남대학교 공업교육연구소 1982 論文集 Vol.5 No.1

Chemical feedstocks and fuels from biomass sources are rapidly attracting our attentions, today. The widespread uses of renewable biomass sources are inevitable for the near-term demise of petroleum sources. The liquefaction of wood (Pinus rigida, Populus euramericana, Salix pseudo-lasiogyne) in au toclave gives the following results. The liquid yield and the conversion are increased by using catalysts and Ni is more effective catalyst than bentonite in liquid yield. The liquid yield is maximum at 300℃(85 atm), with Ni catalyst (for Pinus rigida :0.52, for Populus euramericana : 0.53, for Salix pseudo-lasiogyne : 0.46). Populus euramericana gives more higher liquid yield than others in general. The liquid produced by using Raney-nickel catalyst represents higher combustion heat. The amount of produced gas is increased as the temperature increase from 200℃ to 400℃ without catalysts, but, when catalysts are used, that is maximum at 350℃.

진병래,손흥대,박혜진,조은숙 東亞大學校附設 農業生命科學硏究所 1999 農業生命資援硏究 Vol.8 No.1

들민달팽이의 배자발육은 해부현미경으로 관찰하였다. 산란 후 4일이 경과면서 발육이 급격하게 진전되어, 10일이 지나면서 난 내에서 들민달팽이 유충의 형태를 갖추고, 12일째 부화하였다. 들민달팽이의 배자발육에 따른 난황단백질의 변화는 산란 1일째, 3일째 및 6일째 알의 난황단백질을 전기영동방법으로 분석하였다. 그 결과 배자발육과 함께 급격히 감소되는 난황단백질 관련 밴드를 관찰할 수 있었다. We characterized embryogenesis and egg proteins of Variable field Slug, Deroceras varians. The embryogenesis was observed by light microscopy. The eggs were hatched at the twelfth day after oviposition. The egg proteins of the first day, third day and sixth day after oviposition were analyzed by native-and SDS-PAGE analyses. The results showed that yolk proteins are gradually decreased during embryogenesis.

林恒鎭,金正洙,朴晶來 公州大學校 스포츠科學硏究所 1991 스포츠科學硏究所論文集 Vol.- No.4-5

This study is meant to calculate the change of circulational ability (Heart rate, Blood pressure) and blood components (RBC, WBC, Hb, Hct, Glucose, Total cholesterol, Total protein) at rest (30 minute of rest before exercise), after exercise and at recovery (30 minutes of rest after exercise) by using bicycle ergometer. The boys (5 athletes group, 5 non-athletes group) were chosen form "K" middle school in "K" city and were examined to raise the expectations about exercise. The method of exercise load was decided with a pre-test at 80% of maximum heart rate with bicycle ergometer (Monark : Sweden). 2 minutes of warming up at 50 in 0 kp was done, and soon without rest, main exercise was done for 5 minutes at 50 in 30 kp. Blood circulational ability and blood components were examined three times respectively at rest, after exercise and at recovery. Blood circulational test was taken at sitting position using finger for heart rate and a Sphygmemanometer (Tycos type, Auto) 5cc of blood was collected using one time injector through the antecubital vein and soon 1cc of blood (anticoagulated, EDTA-2k) was examined for blood components change with Auto Cell Counter (ABX : France). The rest of the blood was placed in a plane tube. Later a biochemistrical test was took with Hand Chemistry Analyzer (Gylford : U.S.A) and Auto chemistry Analyzer (Gylford : U.S.A). Experimental items were physique examination (Height, Weight, Chest), circulational ability test (Heart rate , Blood Pressure), hematological test(RBC, WBC, Hb, Hct) and biochemistrical test (Glucose, Total cholesterol, Total protein). The results were compared and analyzed according to experimental items, Standard deviation and mean were made by SAS package program at rest Exercise, and at recovery, The T-test about the difference in average between athletes and non-athletes was made at level of α=0.05, α=0.01 The results are as follows. 1. At rest , the heart rate of the athletes and non-athletes did not have statistical differences, but after exercise, both groups showed rapid increase with concerning difference (p<0.01). 2. At rest, the maximum blood pressure (at systolic) was lower for the athletes group with no statistical significance for both of the groups. After exercise, both groups showed high increase, and at recovery both groups showed quick recover rate. There were no concerning difference both at after exercise and at recovery. 3. At rest the blood components showed less RBC's and WBC's than the normal adults and an average rate of Hb's and Hct's. Only WBC's and Hb's showed statistical difference (p<0.05, p<0.01). 4. After exercise, both groups showed low increase of RBC's Hb's, and Hct's but WBC's showed high increase WBC's Hb's and Hct's showed concerning increase (p<0.05) 5. At recovery, both groups showed approximately 95% recovery rate of RBC's Hb's and Hct's of the blood components, but WBC's showed a high recovery rate of 106%. Only WBC's and Hb's showed statistical difference (p<0.05) 6. At rest, Glucose and Total cholesterol was lower in athletes group but there were no statistical difference in both groups. After exercise both groups showed low increase in them. Glucose showed concerning difference (p<0.01) At recovery, both groups showed rapid recovery rare, but no concerning difference. 7. At rest, Total protein was low in athletes group with no statistical significance. After exercise, both groups showed low increase with no concerning differences. At recovery, both groups recovered quickly, but were no concerning differences. Concluding the above, compared to the non-athletes group, the athlete group showed low numeric value in blood circulating ability and change in blood components at rest, after exercise and of recovery. The low numeric value in blood circulating ability and quick recovery seems to reason form everyday planed and regular exercise in which physical and biochemical changes occur which gives the ability to adjust to the moving parts. The future subject is to understand the effect to the students of early growth which happen by the influence of developing society and to do continuous research of age, sex distinction, and areas to judge the details and intensity of physical strength training, and need to research with long and planned physical strength examination.

The Structure of CP

尹恒鎭 수원대학교 2006 論文集 Vol.24 No.-

생성문법에서의 기능범주(functional categories)에 관한 관심은 굴절어미는 통사적인 분포의 반영이라고 주장한 Chomsky (1957)에서부터 시작되었다. Chomsky (1986)는 모든 범주는 그 것이 기능범주건 어휘범주건 상관없이 최대투사(maximal projections)를 갖는다는 소위 확대 X'-이론 (Extened X'-theory)를 주창하였다. 이러한 전통은, Rizzi (1997)에 이르러 명제적 내용(propositional contents)인 IP의 외곽(left periphery)의 여러 가지 이동 현상을 설명하기 위해서는 보문소구조를 좀 더 나누어 더 많은 구조를 상정해야 한다는 소위 분할보문소가설(split CP hypothesis)을 주창하게 되었다. Rizzi는 보문소 체계를 문장의 서법을 결정하는 ForceP, 주제가 이동하여 투사되는 TopP, 초점이 이동하여 투사되는 FocP, 그리고, 시제와의 일치를 관장하고 명제와의 경계가 되는 FinP로 나누고, 이에 입각하여 여러 가지 통사현상을 상대적 최소성(relativized minimality)조건으로 설명하려 하였다. 이 논문은 이러한 분할 보문소 가설이 일부 한국어의 절 구조에도 적용될 수 있음을 보이고, 또한 어떠한 절에서는 적용되고 어떠한 절에서는 적용될 수 없는 지를 보이려는 데 그 목적이 있다. 우선, 분할보문소가설에 대해서 자세히 살펴본 후에, 한국어의 여러 절에 이 가설이 적용될 수 있는 지를 여러 가지 통사적 현상을 통해 밝혀 보려한다.

Purpose : To find the cause of root curvature by use of panoramic and lateral cephalometric radiograph. Materials and Methods : Twenty six 1st graders whose mandibular 1st molars just emerged into the mouth were selected. Panoramic and lateral cephalometric radiograph were taken at grade 1 and 6, longitudinally. In cephalometric radio graph, mandibular plane angle, ramus-occlusal plane angle, gonial angle, and gonion-gnathion distance (Go-Gn distance) were measured. In panoramic radio graph, elongated root length and root angle were measured by means of digital subtraction radiography. Occlusal plane-tooth axis angle was measured, too. Pearson correlations were used to evaluate the relationships between root curvature and elongated length and longitudinal variations of all variables. Multiple regression equation using related variables was computed. Results : The Pearson correlation coefficient between curved angle and longitudinal variations of occlusal plane-tooth axis angle and ramus-occlusal plane angle was 0.350 and 0.401, respectively (p<0.05). There was no significant correlation between elongated root length and longitudinal variations of all variables. The resulting regression equation was Y=10.209+0.208X_(1)+0.745X_(2) (Y: root angle, X_(1): variation of occlusal plane-tooth axis angle, X_(2): variation of ramus-occlusal plane angle). Conclusion: It was suspected that the reasons of root curvature were change of tooth axis caused by contact with 2nd deciduous tooth and amount of mesial and superior movement related to change of occlusal plane.

Actinomycosis is defined as a chronic, specific, suppurative, granulomatous disease caused mainly by the anaerobic, gram positive organism, Actinomyces israelii. Actinomycosis in the salivary gland is a rare disease that is caused by an inhabitant of the normal flora. We report the case of the actinomycosis of submandibular gland. A 53-year old man presented with the swelling on left submandiblar area. The lesion was not painful but had been increasing for about 10 days. In the CT view, the internal portion of the mass showed homogeneous moderate signal. The mass had continuities with the inferior portion of the left enlarged submandibular gland. In the MRI, there was a mass that showed a buldging pattern inferiorly in the left submandibular gland without bony invasion sign. The biopsy shows the colony of special organism. Many filaments are discovered with clubbed ends diffused from center of colony. We diagnosed this disease as actinomycosis in the submandibular gland by the postoperational biopsy.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.
