Spontaneous retroperitoneal hemorrhage due to hemophilia A with impaired coagulopathy is very rare. Spontaneous retroperitoneal hemorrhage has been recorded as having originated from many retroperitoneal organs and blood vessels, and it may be due to local and/or systemic factors. In the majority of the patients, kidney and adrenal gland were the major site of hemorrhage. The systemic causes of spontaneous retroperitoneal hemorrhage are anticoagulation therapy and chronic hemodialysis. During the course of these treatments, hemorrhagic complications may occur at many site, including the retroperitoneal space. Blood dyscrasias including leukemia, polycythemia, sickle cell trait and hemophilia have been reported associated with spontaneous retroperitoneal hemorrhage. We report a case of spontaneous retroperitoneal hemorrhage occurred in a gemophilia A patient with brief review of literature

상처받은 주체의 치유, '몸'과 '세계'의 이중억압을 넘어서 : 『달력공장 공장장님 보세요』를 중심으로 본 김혜순의 시 세계

This study seeks to investigate the interplay between 'body' and 'object' in the poetry of Kim, Hye-Soon. In Kim's poems, the body is the source of interminable existential crises and also the basis for suffering. Futthermore, the outer world that the body occupies proves to be no less an aggressive threat to the subject. In an attempt to effectively overcome this 'double oppression,' Kim foregrounds both the inner and the outer sphere affecting the body. However, in terms of the inner sphere, the wounded subject fails to overcome the limits sets by the reality principle. Likewise, in terms of te outer sphere, the attempt at the pluralization of the subject is also doomed to failure, insofar as the process f convergence back to a singular self ultimately comes into play. In the end, the yoke of multiple oppression can only be surmounted by re-establishing the relationship between the wounded subject and the external savior.

Background: A hyperosmolar nonketotic state has been known to have a high mortality, and even now, despite this high mortality, only a few studies of this disease have been performed. We studied the prognostic factors for the hyperosmolar nonketotic state. Methods: We retrospectively studied the cases of 40 patients who were in a hypersomolar nonketotic state when admitted to Sanggye Paik Hospital during the 6-year Period from 1995 through 2000. We divided the hyperosmolar nonketotic patients into two groups, the complete recovery group and the incomplete recovery group, and compared the clinical features, the laboratory findings, and the precipitating factors between two groups. Results: 1) A total of 40 patients were studied: 24 in the complete recovery group and 16 patients in the incomplete recovery group. The mortality rate was 32.5%. 2) No significant statistical difference existed among the clinical features of the two groups, except for the sex(p<0.01). 3) Among the laboratory findings of both groups, analysis revealed that the effective osmolarity was significantly higher among those in the incomplete recovery group(p<0.01). Serum sodium concentration was also significantly higher among those in the incomplete recovery group(p<0.01). Serum creatinine was also significantly higher among those in the incomplete recovery group(p<0.05). Serum bicarbonate concentration, on the other hand, was significantly lower among those in that group(p<0.05).4) Infection was identified as the most common precipitating factor(62.5%). Among the precipitating factors of the two groups, there were significant statistical difference in pneumonia, UTI, and inappropriate glucose control. 5) A significant statistical difference existed among the initial level of consciousness of both groups(p<0.05). 6) The only significant independent factor responsible for prognosis of nonketotic hyperosmolar state patients was the sex. Conclusion: The sex was only significant independent prognostic factor of nonketotic hyperosmolar state patients.

Orotic acid 의 과잉 섭취는 지질대사의 이상으로 인한 간 장해를 야기시키는 것이 알려져있다. 특히 지방간 생성에 대하여 관심을 가지게 되어서 본 연구는 orotic acid에 의한 혈청, 腎臟및 肝臟의4 지질 농도에 미치는 영향에 대하여 검토하였다. 시판 분말 chow 식이에 orpotic acid 1% 첨가, 무첨가한 식이를 21일간 90g전후의 성장기 Spragud-Dawley 系 웅성 쥐에 급여하였다. 그 결과 orotic acid 1% 첨가 식이에서 혈청 cholesterol, triglyceride및 phospholipid 농도는 각각 5% 수준에서 유의하게 저하하였다. 肝臟의 triglyceride농도는 5% 수준에서 유의하게 저하하였다, Orotic acid 첨가 식이에서 肝臟중량은 증가한 반면 腎臟중량은 저하하였다. Orotic acid 1% 첨가한 군에서 肝臟및 腎臟의 phospholipid 조성에의 영향은 인정되지 않았으나, 腎臟의 lysophosphatidylcholine은 높은 증가율을 보였다. 肝臟 phospholipid와 비교하여 腎臟에서는 sphingomyeline phospphatidylethanolamin은 유의하게 높은 분포를 나타냈다. 腎臟 phospholipid의 지방산 조성중에서 linoleic acid(18:2)가 상승하고 arachidonic acid (20:4)가 감소하였다. It was generally known that over-ingestion of dietary orotic acid caused hepatic disorder by the lesion of fatty acid and cholesterol synthesis in rats. The present study was carried out to investigate the effects of dietary orotic acid on the lipid composition of serum. liver and kidney of rats. For the experiments rats were fed with commercialized chow powder diet in the presence or absence of 1% orotic acid. The prepared diets were fed to male rats (Sprague-Dawley strain. 90∼100g of body weight) for 21 days. According to the results, orotic acid treated group showed that each concentration of serum cholesterol, triglyceride and phospholipid was significantly decreased (p<0.05). The centration of liver triglyceride was significantly decreased (p<0.05). In the presence of 1% orotic acid, the weight of liver increased while that kidney decreased. The treatment of orotic acid seemed to have no effects on the phospholipid composition in liver and kidney, except the kidney lysophosphatidylcholine. In the comparison of the phospholipid composition between liver and kidney, the levels of sphingomyeline and phosphtidylethanolamine in the kidney were higher than those in the liver. Among the composition of fatty acid in kidney, the concentration of linoleic acid (18:2) was increased, and the concentration of arachidonic acid(20:4) was decreased with the addition of the orotic acid.

Background: In emergency department, there are many drunken patients with various emergency medical situations. In these patients, evaluation and management of the medical problems are delayed from time to time because of the uncooperative nature of the patients and because of consciousness and sensory changes. A precise evaluation can only be obtained when the patients become sober. For this purpose, most clinicians start IV fluid loading. This study was carried out to evaluate the effect of IV fluid(normal saline and glucose solution) on the rate of ethanol clearance in such patients Methods: Ten volunteers(healthy males in their twenties and with a Michigan alcohol screening test below 4) were enrolled in this study. Alcohol intake was restricted to at least 48 hours before the test and food intake to at least 4 hours. For the test, A predetermined dose of ethanol(1 gm/kg) was given to the volunteers. Each volunteer was tested on three consecutive times with 3 or more days interval for alcohol wash out period . On the lst day, the volunteers received ethanol only per os. On the second day, they received ethanol and a liter of IV 10% dextrose solution. Each day, blood was drawn from the antecubital vein to measure the ethanol level at the time of ethanol ingestion and at 0.5, 1, 1.5, 2, 3, 4, 5 and 6 hours after ingestion. The repeated measure ANOVA test was used for the statistical analysis. Results: The difference in the blood ethanol level between the 3 test was F=1.7, p=0.184 and the difference corrected by the time factor was F=0.32, and p=0.985. Conclusion: There was no significant difference in the blood ethanol level between the tests. In conclusion, the IV normal saline or glucose solution does not accelerate ethanol clearance in suffering

DNA回復에 미치는 Poly(ADP-ribose)의 影響에 관한 硏究

金碩煥,鮮于洋一 東亞大學校 1990 東亞論叢 Vol.27 No.1

Effects of 3-aminobenzamide(3-AB), a potent inhibitor of poly(ADP-ribose) polymerase, on DNA replication was determined in CHO cells treated with methyl methanesulfonate(MMS) or UV-light by alkaline s ucrose gradient sedimentation analysis. MMS has been thought to inhibit the replication intitiation in mammalian cells, but we could also observe the inhibitory effect on chain elongation in CHO cells. At low concentration of 3-AB, the rate of DNA replication was not inbibited but at high concentration was shown in dose dependent manner. When MMS-treated cells were subsquently exposed to 3-AB, additive ingibitory effects were brought out. this result may be due to increases of single stand breaks by 3-AB. In the case of treatment with UV-light and 3-AB, hihg concentration of 3-AB induced the additive inhibitory effect on DNA replication, but low concentration of 3-AB alleviated unexpectedly the inhibitory effects of UV-light alone.

우리나라 리스會計制度의 改善方案에 관한 硏究 : 現行 리스會計處理基準을 중심으로 The Current Leases Accounting Standard

金錫煥 상명대학교 논문집 1987 상명대학교논문집 Vol.20 No.-

Korea's current lease' accounting standard bears a great deal of inconvenience and undue advantage against the lessees, which is fundamentally caused by the fact that the accounting standard was established, upon request of lessors and in favor of them, by two accounting corpor ations, Samil and Dongyong, and that the object of the Lease Act about equipment and facilities is aimed at gaining profit from the lease business. This means that many factors in the accounting standard inclined toward the interest of lease companies. Since accounting information have a considerable influence on the business activities, the importance of fairness and inconvenience of accounting standard cannot be underestimated. Some sufficient and closer re-examination on the Act for lease accounting should be made. Besides those problems mentioned above, this thesis reveals a number of other controversial and reformable points in the Act as follows. 1) Since it is a conceptual fallacy to put the bargain purchase option together with the bargain renewal option, the two concepts must be differentiated from each other. 2) It. is in reality almost impossible to get some profit from the bargain purchase option made use of by lessors, but it is stated conversely. 3) Depreciation of the leased assets is prescribed in the same way as actual assets, but that of financing lease should be made along with lease term. 4) In case of depreciating leased liabilities, which one of the interest rate rules should be adopted is not specified. This paper proposes that the interest rate used in lessee's evaluating the present value should be applied unchanged to this occasion. 5) The principles about residual value are not provided. Its concept and the rules for accounting procedure ought to be provided. 6) According to the lease classifying standard, danger and advantage arisen from the ownership are prescribed to be transfered to lessees only when the economic useful life ends. But a financial report of lease business is dependent upon the actual transfer of danger and advantage resulting from the ownership of leased property. 7) All the Financing leases of lessors, without taking sales-type lease into consideration, are regarded as direc-??financing lease. This must be point out an another conceptual fallacy, since it is presumed that the profit source of lessors is restricted to interest receipts. Some proper complements are therefore required on this item. 8) No principles for the initial direct costs can be found in the Act. Its concept and basic accounting must be set up in concrete terms. In order to show the said controversial and reformable points, this paper consists of five chapters. ⅰ) Introduction ⅱ) The Current State of Korea's Lease Finance ⅲ) Korea's Lease Accounting System ⅳ) Problems on Lease Accounting Standard ⅴ) Conclusion

The purpose of this study is to clarify correlations between soil environments and the growth of trees in urban park and green areas and thereon analyze effects of seasonal changes in such environments on such growth. To determine seasonal factors of soil affecting the vitality of Pinus thunbergii, first of all, the study designated the vitality as a dependent variable and soil hardness, moisture, pH, K, Na, Mg and Ca as independent variables. Then the study performed Pearson's coefficient analysis. Based on findings from the analysis, the multiple regression analysis were carried out. The result of the study can be described as below; When correlations between the independent and dependent variables were examined using Pearson's correlation analysis, it wa found that the vitality, soil hardness, K, Na, Mg and Ca were significant at the level of 5%. Among those significant variables, the vitality and Mg were most correlated with the coefficient of 0.415, while K and Mg were least correlated with that of -0.235. Considering findings from the coefficient analysis, this researcher performed multiple regression analysis to determine soil factors influencing the growth of Pinus thunbergii. As a result. it was found that the growth was most influenced by Mg, followed by soil hardness and Ca in order. To clarity what soil factors influence the growth of Pinus thunbergii in spring, the researcher carried out multiple regress ion analysis to find that the growth was most influenced by pH. followed by soil hardness. Then the researcher applied multiple regression analysis to determine soil factors influencing the growth mentioned above in summer. The analysis showed that no soil factors affected the vitality at the significance level of 5% for t. Concerning relative importance based on the standard regressive coefficients, or β, K had the coefficient of 0.437 suggesting it was relatively more influential comparing to the other independent variables. Soil factors which influence the growth of Pinus thunbergii in fall were determined through multiple regressive analysis to find that the growth was influenced by soil hardness in the same season. Also such factors as affecting the growth mentioned above in winter were clarified using multiple regressive analysis to show that the growth was most influenced by soil hardness, followed by Mg, pH and Ca in order. In conclusion soil hardness had effects on the growth of Pinus thunbergii throughout four seasons except summer. Thus soil hardness is the most important factor for the growth of Pinus thunbergii. 본 연구는 도시공원녹지의 토양환경과 수목생육과의 상관관계를 구명하고, 계절별 토양 특성의 변화가 수목의 생육에 미치는 영향을 분석하고자 하였다. 곰솔의 수목활력 도에 영향을 미치는 계절별 토양인자를 알아보기 위하여 수목활력 도를 종속변수로 지정 하고 토양경도, 토양수분함량, 토양 pH , K, Na, Mg,Ca함량을 독립변수로 지정하여 Pearson 상관 분석을 수행한 후, 그 결과를 이용하여 다중 회귀분석을 실시하였으며 그 결과는 다음과 같다. 1) 각 변수들 간의 Pearson 상관분석을 실시한 결과, 유의확률 값 5%수준에서 유의한 변수는 수목활력도와 토양경도, K, Na, Mg Ca로 나타났다. 유의한 변수들 중 에서 수목활력도와 Mg가 상관계수 0.415로서 상관성 이 높게 나타났고 K와 Mg가 상관계수 - 0.235 로 상관성이 가장 낮게 나타났다. 2) 상관분석 결과를 바탕으로 곰솔의 생육에 미치는 조사지의 토양인자를 알아보기 위해 다중 회귀 분석한 결과, 경도, Mg, Ca가 수목활력 도에 유의적인 영향을 미치는 것으로 판단할 수 있었으며, 곰솔의 생육에 영향을 미치는 토양인자는 Mg, 토양경도, Ca 순으로 나타났다. 3) 곰솔의 생육에 영향을 미치는 봄철의 토양특성은 pH, 토양경도 순으로 나타났고, 곰솔의 생육에 영향을 미치는 여름철의 토양 특성은 없는 것으로 나타났으며, 곰솔의 생육에 영향을 미치는 가을 철 의 토양특성은 토양경도로 나타났고, 곰솔의 생육에 영향을 미치는 겨울철의 토양특성은 토양경도, Mg,pH, Ca 순으로 나타났다. 본 연구의 결과, 곰솔의 생육에 영향을 미치는 토양특성 중에서 토양경도는 여름을 제외한 모든 계절에 영향을 미치는 중요한 토양인자로 나타났다.
