콩팥의 사슴뿔 결석에 동반된 거대세포 종양 유사 증식증 - 1예 보고 -

A 62-year-old man with left flank pain and hematuria was shown to have a staghorn stone in left renal pelvis. Grossly, renal pelvis and calyces were markedly dilated with cystic and hemorrhagic degeneration and renal parenchyma was atrophied. A tumor-like mass was located in a hemorrhagic cyst of the renal upper pole. This mass consisted of giant cells and stromal cells mimicking a giant cell tumor of bone. This giant cell tumor-like proliferation may represent a response to hemorrhage into a cystic cavity. Recognition of this finding is important to avoid the over-diagnosis of neoplastic lesions.

AC motors were mostly used as constant speed Machines in the past. Remarkable is the progress of the latest technique of speed control. In Particular thristors that came into the world about a decade ago and their applications to the field of speed control are really out standing. A number of effective speed control systems have been developed, and as a result away with the induction machines. Because of their distinctive feature of sturdiness and easy maintenance, induction motors are coming into the sphere of DC motors in future. Herein are introduced various speed control systems of AC motors.

The effect of reducing flood magnitudes, flood stages, and flood damage by upstream reservoir regulation are investigated in this study. The analytical procedures which has been established newly, are treated through this study for 7 index stations and same numbr of reaches. The method of this study could be expressed briefly as following procedures. Using stage-frequency relations and the potential damage survey data, damage-frequency relations are established, and from this, average annual flood damages computed. By holding out portions of the floods with various amounts of flood control storage in 6 reservoirs in the basin, routing were made to establish modified stage-frequency relations. From damage frequency relation, average annual damages are computed with and without condition of each control volume. The study result are concluded as follows; (1) The relationtship of corresponding water level between nearby stations are useful tools to adjust error of the data due to observation error and change of the gaging location. (2) The number of records about 10 years could not be applied for the statistical methods of flood frequency analysis. (3) The regional skew factors are recommended to apply flood frequency study by the log-Pearson Type III method. (4) The effect of damage reductions are greatly affectedin accordance with the routed flood. Therefore application of the Typical Tributary Contribution Flood are reasonable for this type of study. (5) In the North Han, effect of damage reduction due to the lacation of control point are gradually increased from upstream to downward until the confluence of North and South Han. (6) In the South Han, control effect are increased from Chungju to Yeoju where the maximum effect are analyzed and then decrease gradually until the confluence. (7) Better hydrologic and topographic combinations for the flood control are existed in South Han to compare with North Han in this study results.
영화 “그랑블루”를 통해 살펴 본 Narcissism의 정신분석적 이해
김한성 한국정신분석학회 2021 精神分析 (Psychoanalysis) Vol.32 No.3
Individuals with unhealthy narcissism due to social changes are causing various social problems. Kohut noted that primary narcissism is essential for growth and development and persists in life, covering all facets of a personality. This thesis analyzes how nar- cissism affects an individual’s personality from the perspective of the movie “Le Grand Bleu.” Enzo had a strong rivalry for Jacques, which killed him. Narcissistic wounds play a key role in this competitive spirit, and there was an attempt to restore narcis- sism as a child by projecting Enzo’s ideals on Jacques. Jacques appeared to be in a secondary narcissistic state, living in isolation from the loss of his parents as a child. While meeting Enzo and Joanna, the relationship with the world begins again, but due to Enzo’s death, the original state of libido distribution was re-enacted and reality verification was lost. Meanwhile, Jacques showed his death instinct throughout the film and made a break from the people around him. Joanna’s love for Jacques is analyzed in terms of object-choice. Joanna followed a narcissistic pattern, seeing Jacques as a proxy for ego ideal. Recently, a series of social problems caused by individuals immersing unconsciously in excessive narcissism that is not integrated into the ego or superego like the main characters in the movie. It will be an important task for society and psychotherapists to provide empathy and optimal activities to frustrations in these individuals, leading to the growth of healthy narcissism.
薦骨 前方의 腫塊를 동반한 Currarino Triad : 증례 보고 Case Report
김한성,박철완,백광흠,이언 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.8
The Currarino triad is a unique complex of congenital caudal anormalies including anorectal malformation, sacral bony abnormality, and presacral mass. Histologically the presacral mass has been identified as a meningocele, teratoma, enteric duplication of a combination of this. A Case of female infant with this triad was presented and was successfully treated by surgery. The presacral mass was lipomyelomeningocele. The clinical features, unique radiologic findings, and importance of a correct diagnosis of currarino triad were reviewed.
Korean Missionaries: An Unbroken Horse Power for World Mission
김한성 한국복음주의선교신학회 2009 복음과 선교 Vol.11 No.-
This paper investigates the identity of Korean missionaries. To do so, I look at the subject in a couple of different ways. After providing with an overview of Korean missionaries, I use two social factors of grid and group which were first suggested by Mary Douglas and used by Sherwood Lingenfelter. I, then, use four frames of organizations. The argument of this paper is that they fall into the categories of the bureaucratic and the individualist type and provide the basis of the argument.

병렬 커패시터를 이용한 직류 초퍼의 출력특성에 관한 연구
金漢星 건국대학교 1984 學術誌 Vol.28 No.2
DC choppers are usually to control the output of DC motor by varying the average output value of chopper. But the chopped output by the switching operation gives rise to the ripple in the output side and the harmonics in the source side. Also the discontinuous current mode makes the output characteristics worse in speed regulation, system gain and accuracy than the continuous mode. To improve these disadvantages, the capacitor chopper circuit is suggested and its characteristics are investigated. And the analytical expression is approximately derived from the equivalent circuit of the output capacitor filter C.
