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.

The aim of this study is to report 2 cases of acute promyelocytic leukemia who died from intracranial hemorrhage following leukapheresis and to provide proper preventive measures against hemorrhage following leukapheresis. From 1994 to 1997, a total of twenty-six patients with leukemia underwent leukapheresis to control hyperleukocytosis at Ajou University Hospital. Two patients with acute promyelocytic leukemia received all-trans retinoic acid but developed drug-induced hyperleukocytosis. Shortly after leukapheresis, they died from intracranial hemorrhage. The risk factors for fatal hemorrhage are thought to be coexisting disseminated intravascular coagulation(DIC), thrombocytopenia aggravated by leukapheresis, exacerbated coagulopathy related to mechanical trauma through leukapheresis and the excess use of citrate during leukapheresis. To reduce the risk of the bleeding associated with leukapheresis, it is necessary to replace platelet sufficiently before and after leukapheresis and to give calcium to correct coagulopathy induced by excess citrate which is used as anticoagulant as well as the correction of disseminated intravascular coagulation.

노자상이주(老子想爾注) 양생윤리 -양생의 시대적 변용이라는 관점에서-

Nurturing life is one of the most important thoughts in ancient china. Xiang Er Zhu is the bible of Wou Dou Mi Tu(五斗米徒). I investigated Xiang Er Zhu from the perspective of Nurturing Life in this treatise. Nurturing Life first shown in Zhuang Zi(莊子) and Guan Zi(管子) had developed through Qin Hin(秦漢) period and changed itself in accordance with the demand of age. This change can be told to be the development of Nurturing Life Theory. In post han period, Nurturing Life Theory had to fit itself into the age request, socialization. Nurturing Life Ethic in Xiang Er Zhu is the response to the request. China had some thoughts of the original form of Nurturing Life Ethic. Tai Ping Jing(太平經) is one of them. But the oldest model we can find would be in Guan Zi. In Guan Zi, we can find the thought that feeling stability cause health of mind and body. Nurturing Life in Xiang Er Zhu formed on the foundation of that thought. But it did not follow the same logic. It borrowed such concepts as Tai Yin(太陰), Tian Cao(天曹) from folk religion. Folk religion was familiar with the chinese and had the power to enforce moral behavior. People should keep Dao Jie(道誡) not to lessen his life by punishment of Tian Cao. But Zao Shen(조神) or San Shi(三尸) that report guilty of person to Tian Cao in Daoism Ethic is not in Xiang Er Zhu. Instead, Xiang Er Zhu proposed the technique of Shi Jie(尸解), revival from death. Nurturing Life Ethic in Xiang Er Zhu is folk religion ethic founded on the traditional ethic orienting feeling stability and the cohesion of life and ethic behind traditional ethic.

Air-jet looms represent a major step in the development of shuttleless weaving because of their ability to weave a wide range of yarns at high speeds. Air-jet weaving involves inserting a pre-measured length of yarn through the wrap shed by means of compressed air. The analysis of air flow characteristic of the main nozzle and acceleration tube is necessary to loom performance. We examined the effect of the main nozzle with different acceleration tube as well as diameter. And also, we compared to the performance of straight type tube and laval type tube.

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.

전 세계의 환경문제인 기후변화에 적극적으로 대응하기 위해 새로운 국가 비전인 저탄소 녹색도시을 견인할 수 있는 지역·권역별 녹색도시화 특성화 방안을 제시함으로서 기후변화에 대응할 수 있는 방안을 모색하고자 한다. 부산 원도심인 서구 충무동·남부민동의 풍부한 자연자원과 다양한 역사·문화자원을 활용한 저탄소 녹색성장과 환경보호를 양립시켜 새로운 성장동력과 지역경제 활성화로 도시재생방안을 마련한다. 녹색기술을 활용한 경사지 주거재생, 도심형 항만재생, 원도심 상권재생의 3대 목표를 설정하고 6대 핵심 전략을 중심으로 지속가능한 녹색도시를 조성한다. 서구 저탄소 녹색도시 선도사업에서 노후화된 주거시설을 개선하기 위한 하우스 프로젝트을 통해 지역성에 맞는 주거모델을 제시하고 친환경 기술요소를 이용하여 자체에너지 생산, 그린 인프라를 이용하여 생태복원 및 바람길을 연결하여 미기후 조절을 가능하게 한다. 그리고 도심형 항만재생에서는 공동어시장에 발생하는 유기성폐기물을 바이오매스시스템 구축을 통하여 바이오에너지를 생산하며 해양친수공간 조성과 천마산을 연결하는 그린네트워크를 형성하여 부산의 대표적인 저탄소 녹색성장 명품도시로 조성한다. By suggesting the green city characterization measure for each region and zone that can lead the low carbon green city which is a new national vision in order to actively cope with the climate change, the global environment issue, we aim to seek for the measure to build up low carbon green city suitable for local characteristics. With low carbon green growth and environment protection by using abundant natural resources and various historical/cultural resources in Seo-gu Chungmu-dong and Nambumin-dong, the old downtown of Busan, the city reclamation measure can be prepared based on a new growth driving force and local economic vitalization. It is a general measure related to easing and adapting to climate change like water circulation, including setting up the three main goals like reclamation of residence on slopes, urban ports and business districts in old downtown based on green technology, and the six core strategies like establishing system of carbon reduction through using low carbon energy, improving the transportation structure through introducing green traffic system, having water/resource circulation system through low carbon circulation resource, having green construction system through applying green technology and environmentfriendly materials, building up ecotype greens based on the carbon absorption system through management of greens and urban forest and creating green community through private and public green partnership. It is possible to control microclimate by connecting wind ways, restoring ecology through using green infrastructure and producing its own energy based on environment-friendly technical elements as also suggesting residental models suitable for local characteristics based on the house project to improve obsolete residential facilities with low carbon green city leading project in Seo-gu. For the urban port reclamation, bio-energy is produced by building up biomass system through organic waste generated in the joint fish market. As also forming waterfront and green network connecting with Mt. Cheonma, it can be the representative low carbon green growth city in Busan.

위암 주위 점막에서 장화생과 Carcinoembryonic Antigen (CEA) 표출과의 관계에 대한 연구

윤석중,강상균,김창진 순천향대학교 1994 논문집 Vol.17 No.4

Stomach carcinoma is the most common tumor in Korea and it's pathogenic mechanisms have not been elucidated. Through vast histologic studies on the mucosa adjacent to the carcinoma, intestinal metaplasia was known as one of the possible candidates for the precancerous lesion of gastric carcinoma. Moreover, further close relationship between intestinal metaplasia and gastric carcinoma was brought out by several lines of study showing that alpha-fetoprotein and carcinoembryonic antigen, which are oncofetal protein expressed frequently in malignant tumor or transforming growth factor alpha, which is mitogenic oncoprotein, are expressed in metaplastic mucosa. To investigate the close relationship between intestinal metaplasia(IM) and gastric carcinoma, immunohistochemical expression of carcinoembryonic antigen was studied on the mucosa adjacent to gastric carcinoma(n=90), to peptic ulcer(n=20) and on normal mucosa resected for duodenal ulcer(n=20). The results were as follows; 1. Among 90 gastric carcinomas, type Ⅰ, type Ⅱ and type Ⅲ intestinal metaplasia were 11(24%), 25(28%) and 32(36%) respectively. 2. CEA was expressed in 45% of type Ⅰ metaplasia, 84% of type Ⅱ metaplasia and 91% of type Ⅲ metaplasia. 3. Among 20 cases of peptic ulcer, 15 cases(75%) showed type Ⅰ metaplasia, while type Ⅱ and type Ⅲ metaplasia were 2 cases(10%) each. 4. CEA was expressed in 80% of type Ⅰ metaplasia, and all 2 cases of type Ⅱ a nd typeⅢ metaplasia showed CEA positivity. 5. Among 20 cases of normal gastric mucosa resected due to duodenal ulcer, type Ⅰ, Ⅱ and Ⅲ metaplasia were found in 13 cases(65%), 3 cases(15%) and 2 cases(10%) respectively. 6. CEA was expressed in 9(69%) among 13 cases of type Ⅰ metaplasia, in 2(67%) among 3 cases of type Ⅱ metaplasia and in all 2(100%) cases of type Ⅲ metaplasia. Above results suggest that the mucosa adjacent to gastric carcinoma show frequent sulphomucin secreting incomplete intestinal metaplasia and most of the metaplastic lesion express CEA, which imply close relationship between sulphomucin secreting intestinal metaplasia and gastric carcinogenesis. However, the metaplasia occurred in the mucosa adjacent to peptic ulcer or in normal mucosa resected dor duodenal ulcer showed CEA positivity as well, though the number of cases is not enough. Therefore, further studies on the relationship between sulphomucin secreting intestinal metaplasia and gastric carcinoma should be done to elucidate the pathogenesis of gastric carci

Accurate position estimation is required for mobile robot navigation. To estimate current position, mobile robot uses sensors. As one sensor or two sensors system is insufficient to estimate accurately, it is necessary to use sensor fusion method. Mobile robot can obtain redundant and complementary information by using sensor fusion method. It is possible to estimate current position more accurately than one sensor or two sensors system. Sensor fusion system is composed of vision sensor, ultrasonic sensors and encoder sensor. Personal computer and interface board control three different sensors. Extended Kalman Filter(EKF) method using three different sensors is proposed for sensor fusion. The validity of the proposed sensor fusion method is proved by experimental results in indoor environment.
