There are many mountains and isn't much development district in Busan area. so, progressing in the large-scale reclamation with the urbanization. It thinks for the climate change in Busan area to accelerate by the reclamation. The way of making improve to the city environment aggravation which comes in the urbanization and the reclamation. There is the city vegetation and city planning in this way. The following was concluded from this study. 1) The minimum temperature rose remarkably in Seoul and Daegu by urbanization but, in this case, the maximum temperature rose remarkably in Busan by progressing of urbanization. 2) As a result of the study, Indoc-kyo plays a role of the wind road but, The very few influences occur. 3) The high-rise apartment building district and the four-lane road compared favorably with the low-rise building district and two-lane road for influx of sea wind.

폴리카프로락탐纖維의 加水分解에 關한 硏究

趙龍錫 대구효성가톨릭대학교 1980 연구논문집 Vol.22 No.2

Polycaprolactam fibers were hydrolysed with 1.0 to 2.0N hydrochloric acid and the effect of hydrolytic conditions on properties of the fibers were examined. The fiber did not show any significant changes in the weight. moisture regain, strength and elongation by varing the acid concentration and the hours of hydrolysis. However, these properties of the fiber were apparently changed by rising the hydrolytic temperature up to 70℃. When the fibers were hydrolysed for 7.5 hours at 70℃ with refluxing the acid(2.0N), they showed a remarkable decrease in moisture regain. They lost a 2.9 per cent of initial weight and they showed a 60 per cent decrease in strength and elongation against control. On contraly, when the fibers were hydrolysed under 60℃, they showed only a 1.7 per cent of weight loss, 1.0 per cent increase in moisture regain and 30 per cent decrease in strength and elongation. It is clear from above results that acid hydrolysis of polycaprolactam fiber at high temperature(above 70℃) drastically disturbes physical properties of the fiber.

운동부하전 섭취한 탄수화물이 운동흰쥐의 심근 및 골격근이 당원량에 미치는 영향을 측정하여 심근과 골격근의 대사적 차이점의 일단을 연구한 본 논문의 결과는 다음과 같다. 심근과 골격근 당원량(mg/ g wet tissue, 이하 단위 동일)은 정상군에서 심근 2.62±0.51로서 골격근의 3.37±0.58보다 낮았다(p<0.01). 심근 당원량은 정상군이 2.62±0.51이었다. 운동 30분에서 대조군은 정상군의 63%수준으로 감소하였으며(p<0.01), 탄수화물섭취군은 정상군의 86 및 90%수준으로 감소하였으나 통계적으로 유의한 차이는 없었다. 탄수화물 섭취군의 당원량은 대조군의 142 및 137%정도로 양군 모두 대조군보다 유의하게(p<0.01) 높았다. 운동 60분에는 대조군은 운동30분의 78%(정상군의 49%)수준으로 감소하였으며(p<0.05) 탄수화물섭취군은 포도당중합체 및 포도당섭취군에서 각각 운동 30분에 비하여 72(p<0.01, 정상군의 62%), 81%정도(p<0.05, 정상군의 73%)로 감소하였다. 포도당 섭취군의 당원량은 대조군의 147% 정도로 대조군보다 유의하게(p<0.01) 높았다. 운동 120분에서 대조군은 운동 60분에 비하여 63%(정상군의 33%) 수준으로 감소하였으며 (p<0.01) 포도당섭취군은 운동 60분의 69%(정상군의 50%)수준으로 유의하게 감소하였으나, 포도당 중합체 섭취군은 차이가 없었다. 탄수화물 섭취군의 당원량은 포도당 중합체 및 포도당섭취군에서 각각 대조군의 202 및 162% 정도로 양군 모두 대조군보다 유의하게(p<0.01)높았다. 골격근 당원량은 정상군이 3.37±0.58 이었다. 운동 30분에서 대조군은 정상군의 69% 수준으로 감소하였으며(p<0.01) 탄수화물섭취군은 포도당 중합체 및 포도당섭취군에서 각각 정상군의 85 및 88% 수준으로 감소하였으나 통계적으로 유의한 차이는 없었다. 탄수화물 섭취군의 당원량은 포도당 중합체 및 포도당섭취군에서 각각 대조군의 125 및 129% 정도로 양군 모두 대조군보다 유의하게(p<0.05) 높았다. 운동 60분에는 대조군은 운동 30분의 77%(정상군의 53%) 수준으로 감소하였으며(p<0.05)탄수화물섭취군은 포도당중합체 및 포도당섭취군에서 각각 30분에 비하여 93(정상군의 80%), 89(정상군의 78%) %정도로 감소하였으나 통계적으로 유의하지는 않았다. 포도당중합체 및 포도당 섭취군의 당원량은 각각 대조군의 152 및 149% 정도로 대조군보다 유의하게 (p<0.001) 많았다. 운동 120분에서 대조군은 운동 60분에 비하여 50%(정상군의 26%) 수준으로 감소하였으며(p<0.001) 포도당 섭취군은 운동 60분의 75%(정상군의 58%)수준으로 유의하게(p<0.05) 감소하였으나 포도당 중합체 섭취군은 대조군의 84%(정상군의 67%)정도로 감소하는 경향을 보였다. 탄수화물 섭취군의 당원량은 포도당 중합체 및 포도당섭취군에서 각각 대조군우ㅢ 255 및 221% 정도로 양군 모두 대조군보다 유의하게(p<0.001) 높았다. 이상의 결과로 미루어 보아 심근과 골격근 간의 생리, 생화학적 특성의 차이에도 불구하고 탄수화물의 섭취후 중등도 정도의 달리기 운동시 근 당원의 함량에 미치는 영향은 정도의 차이는 있으나 같은 경향을 나타내었으며, 골격근에서 심근보다 더 많은 근 당원 절감효과를 나타내었다. 또한 운동전 탄수화물의 섭취시 이러한 근 당원 절감 효과로 장시간의 운동시 심근 및 골격근 당원의 고갈 지연으로 운동수행능력의 증가가 기대되며, 특히 포도당 보다는 포도당 중합체의 섭취시 효과가 더 크리라고 사료된다. The purpose of this study was to investigate the effect of glucose and glucose plymer ingestion on the concentration of the cardiac muscle glycogen at 30, 60 and 12 minutes of the treadmill running in rats. Rats were randomly assinged to normal, control, and carbohydrate groups. Carbohydrate group was divided into glucose, and glucose polymer ingested rats. The experiment was carried out after overnight fasting. Rats were administrated either water (control) of carbohydrates of formulated glucose(6%), and glucose polymer(6%) via polyethylene tube to the stomaach before treadmill run. Exercise was loaded by a treadmill run at the speed of I ㎞/hr for 30, 60, and 120 minutes. The results of experiment were as follows: Glycogen content of the cardiac muscle was lower than that of the skeletal muscle (plantaris) in normal rats. Glycogen content of the cardiac muscle was decreased in proportion to the exercise time compared to normal in control and carbobydrates ingested rats. It decreased in control, glucose, and glucose polymer compared to normal rats in decreasing order at 120 minutes treadmill running (% change of glycogen content of control, glucose, and glucose polymer compared to normal rats were 33, 50, and 63% in the cardiac muscle at 120 minutes of treadmill running respectively). Glycogen content of the skeletal muscle was decreased in proportion to the exercise time compared to normal in control and corbohydrates ingested rats. It decreased in control, glucose, and glucose polymer compared to normal rats in ecreasing order 120 minutes treadmill running(% change of glycogen content of control, glucose, and glucose polymer compared to normal were 26, 58, and 67% in the cardiac muscle at 120 minutes of treadmill running respectively). Change of the glycogen content of the cardiac and the skeletal muscle during treadmill running after glucose and glucose polymer ingestion showed that both muscles had tendency to decrease in proportion to exercise time similarly in control and carbohydrates ingested rats. Decreasing rate of glycogen content of cardiac and skeletal muscles during treadmill running compared to normal in carbohydrates ingested rats was lower than that of control. From these results, it is suggested glycogen content of cardiac and skeletal muscles had tendency to decrease in proportion to exercise time similarly in control and carbohydrate ingested rats. Glycogen content of cardiac and skeletal muscles in carbohydrate singested rats less decreased than that of control during treadmill running compared to normal. Glucose polymer of the carbohydrates ingested rats in considered as the most effective for glycogen sparing according to exercise time in both muscles. Therefore, intake of carbohydrate, especially glucose polymer, before exercise may be increase performance of the prolonged moderate exercise.

Fifty two cases of traumatic diaphragmatic injuries that we have experienced from Jan. 1973 to Oct. 1994 were evaluated. The following results were obtained. The age of the patient was ranged from 1 to 74 years. Male was 38 and female was 14 in number with a ratio of 2.7 : 1. The traumatic diaphragmatic injuries were due to blunt trauma in 35 cases(motor vehicle accident 25, fall down 8, press 1, kick by fight 1) and penetrating trauma in 17 cases(stab wound 15, shot wound 1, explosion 1). In the blunt trauma, the preoperative diagnosis of the diaphragmatic injury was possible in 25 out of 35 cases(71%) and in the penetrating trauma, 15 out of 17 cases(88%). In the blunt trauma, the repture site was located in the left in 22 cases(63%) and in the right in 13 cases(31%). In the penetrating trauma, the rupture site was located in the left in 9 cases(53%) and in the right in 8 cases(47%). In the blunt trauma, 20 cases(63%) were treated within 24 hours and in the penetrating, 15 cases(88%) within 24 hours. In the blunt trauma, the herniated organs into the thorax were stomach(7), omentum(6), spleen(6), liver(5), colon(4), small bowel(2) and in the penetrating, stomach(7), colon(6), omentum(3), liver(2), and spleen(1) were herniated. Injury severity score(ISS) of 35-blunt trauma ranged from 11 to 66 with mean value of 30.6. Mean ISS of survivors and nonsurvivors was 27.6 and 52.7 respectively. The diaphragmatic repair of 49 cases was performed with thoracic approach in 23 cases, thoracoabdominal approach in 7 cases and abdominal approach in 19 cases, and 3 cases were not operated. The postoperative complication and mortality were developed in 16 out of 49 cases(33%) and in 5 cases(9.6%) respectively, and the causes of death were hypovolemic shock(1), combined head injury(2), asphyxia(1), and pulomnary edema and renal failure(1). In conclusion, the injuries of the diaphragm should be suspected in all patients with severe blunt trauma or penetrating injuries at thorax and upper abdominal area near the diaphragm. All of the cases had associated injury and most of deaths were related to the severity of associated injuries.

Prevertebral soft tissue swelling of cervical spine lateral radiogram is well known as an indirect evidence of occult cervical spine injury. But the clinical and statistical value of it has been of debate. We tried to analyse the value of cervical prevertebral soft tissue width as a screening test for cervical spine injury by comparison of two categorized study groups; the control group, traumatized patients without cervical spine injury and the injury and the injury group, traumatized patients with bony cervical injury. The injury group consisted of patients admitted between September 1993 and December 1994 with an ED diagnosis of bony cervical injury. The control group consisted of patients admitted between January 1994 and June 1994 who received cervical spine lateral radiograph because of suspicion of cervical spine injury or as a routine check. In both group, we sampled the patients who received cervical spine lateral rediograph within 24 hours after injury and excluded the patients less than 15 years old and more than 65 years old, In the control group, we confirmed the patients had no problem in cervical spine of follow-up. 101 control patients and 68 injury patients were identified. The injury group was further divided into two subgroups: those with injuries at C1-C3 to the upper injury subgroup and those with injuries at C4-C7 to the lower injury sub group. The prevertebral soft tissue widths of injury group were larger than of control group at C2(mean 6.1mm versus 4.5mm) and also at C6(mean 13.4mm versus 11.2mm). Especially upper injury subgroup had quite large value of C2 prevertebral soft tissue width(mean 14.1mm). Nevertheless, both in C2 and C6, there is no cutoff value with acceptable sensitivity and specificity as a screening test. But the 7mm at C2 and 14mm at C6 had high specificity(90%) and were thought to be a good radiologic indicators of further evaluation.

The evaluation of patients with microscopic hematuria after blunt abdominal trauma has become controversial. We tested the hypothesis that renal contusion can be diagnosed clinically and that these patients do not require radiographic evaluation. To evaluate the association of microscopic hematuria without shock and with renal injury, we reviewed the medical records of 252 patients following blunt abdominal trauma. Microscopic hematuria without shock was noted in 58 of 252 patients. Of the 58 patients 52 had renal contusion, 4 had renal laceration, 1 had a renal rupture and 1 had renal pedicle injury. All of the patients with renal contusions experienced no complications from nonoperative management. But, avoiding a radiopraphic evaluation in patients with blunt renal trauma plus microscopic hematuria and no shock would miss a few cases of severe renal injury.
