TRIP강의 수소에 의한 취성화정도를 확인하기 위하여 산성과 알칼리성 전해질 분위기 하에서 전류밀도와 주입시간을 달리하여 수소를 강제주입시킨 후 sp시험으로 평가하고자 하였다. SP시험결과 산성 전해질 분위기가 알칼리성 전해질 분위기에 비해 수소 취성화가 더욱 민감하게 반응하는 것으로 조사되었다. 또한 산성 전해질은 주입시간과 전류밀도가 수소취성화에 영향을 미치는 인자로 확인되었으며, 알칼리성 전해질은 주입시간이 전류밀도보다 수소 취성화를 촉진하는 요소로 조사되었다. In order to evaluate the degree of hydrogen embrittlement of TRIP steels charged with hydrogen according to varying the current density and the charging time under acid and alkaline electrolyte conditions were tested by small punch test. The results of SP test showed that the degree of hydrogen embrittlement at acid electrolyte condition was more effective factor compared to that of alkaline electrolyte condition. Therefore, all of the charging time and the charging current density were at the condition of acid electrolyte appeared as the main factor of the degree of hydrogen embrittlement in the condition of acid electrolyte. But, it was considered that the charging time compared to the charging current density at the condition of alkaline electrolyte was more effective factor to raise the degree of hydrogen embrittlement.

In a patient with blunt abdominal trauma with small bowel injury, early diagnosis is clinically challenging due to unclear clinical symptoms and signs in the early stage of an injury. On the other hand, a delay of diagnosis of bowel disruption may lead to increased complication and mortality. The diagnostic laparoscopy is very useful for the evaluation of the small bowel injury. Laparoscopy can reduce unnecessary open surgery in a patient with blunt abdominal trauma with subtle symptoms and imprecise findings on abdominal computed tomography. Also it can prevent delay of treatment and be converted immediately to open surgery as soon as bowel damage is revealed. Furthermore, extracorporeal repair of small bowel via mini-laparotomy after a single incision diagnostic laparoscopy in a patient with traumatic small bowel perforation was a feasible and safe alternative to conventional laparoscopy. We are pleased to introduce successfully treated cases by extracorporeal repair of small bowel via mini-laparotomy after a single incision diagnostic laparoscopy in a patient with small bowel perforation after blunt trauma.

복부 팽만과 장천공 및 패혈증성 쇼크로 수술 후 진단된 신생아의 회장 폐쇄증에서 비후성 유문 협착증이 동반된 증례로서 회장 폐쇄증의 산전 진단 및 치료 과정에 있어서 다른 부위의 폐쇄증과의 차이를 인지하고, 문합 수술 후 지속적인 구토 증상을 보이는 공회장 폐쇄증 환아에 있어서 수술과 관련된 합병증 이외에 다른 위장관계의 동반 기형의 유무도 확인해야 하며 그 감별 진단에 비후성 유문 협착증도 고려해야 할 것으로 생각된다. Ileal atresia, a subtype of intestinal atresia, is one of the well-recognized causes of bowel obstruction in newborns. Prenatal diagnosis of intestinal atresia is very important in its management and outcome. Unfortunately, there are few cases of ileal atresia diagnosed prenatally, so more appropriate diagnoses and management plans are needed. As an associated gastrointestinal malformation with ileal atresia, hypertrophic pyloric stenosis is rarely reported. We report one case of postnatally diagnosed ileal atresia associated with hypertrophic pyloric stenosis which was complicated initially by bowel perforation and later by vomiting due to pyloric obstruction. Vomiting in the postoperative period is a common problem. But, if vomiting continues after the operation for ileal atresia, hypertrophic pyloric stenosis should be considered as a possible cause of medically retractable non-bilious vomiting.

이 논문은 국제우주정거장 (ISS)내의 미소중력의 환경에서 5㎏이하의 살아있는 고체, 반고체, 액체 (용기내) 등의 무게를 측정할 수 있는 가속형 우주저울(SMMD)에 대한 것이다. 먼저, 여러 가지 개념을 구현하기 위하여 3가지 형태(가속형, 원심력형, 진동형)의 시스템을 개발하였고, 그 중에서 성능이 가장 우수한 가속형 장비를 우주저울로 선택하였다. 이 논문은 이전 가속형 시스템에서 야기되었던 문제점을 해결하고, 하드왜어 및 소프트웨어를 좀 더 발전된 형태로 개선한 볼 스크류를 이용한 가속형 우주저울을 개발을 설명한다. 이 장비를 가지고 저울로써의 기능과 정확도 등의 성능 시험을 하였다. 측정 분석 결과 현 시스템의 측정 범위는 20g ~ 2㎏ 까지 가능하며, 그 정확도는 0.5% 이내로 우수한 결과를 보여주었다. 이 장비를 바탕으로 하여 앞으로 현 장비를 우주환경에 맞는 FM 개발을 위한 우주급 시스템으로의 개선이 필요하겠다. In this study, we will explain acceleration type SMMD(small mass measuring device) which is able to measure the mass of solid, semisolid and liquid(in a container) materials in the microgravity environment of ISS(International Space Station). First of all, we developed the 3 types(acceleration, centrifugal force, vibration) of systems and selected the acceleration type among them, of whim performance is the best, as the SMMD. This paper is showing the development of acceleration type SMMD using the ball screw motor. this system is improved in hardware and software and solved the some problem for acceleration type test model. With the system, we did performance test for function as a balance and accuracy. The measurement result showed that the range of measurement is 20g to 2㎏ and the accuracy of the system is within 0.5%. With the base of the system, We need to improve the system for developing Flight Model with adapting the space environment.

民俗씨름의 샅바에 關한 硏究

金光植 청주대학교 대학원 1993 우암논총 Vol.9 No.-

Ssirum, our national sport required power and skill, makes our body robust and has a nation’s spirit in it. Also, the development of a nation is based on the peopie’s healthy mind and body, completed by the gymnastic activity. Therefore, Ssinun can be strechted itself as a pannational and public folk gymnastics. However, our Ssirum becomes gradually amused, professionalized, and exceedingly commercialized on the level of the folkgame according to the changes of the times. As a result of it, we seem to be forgetful of its value as an essential folk match. We should have the calling conscience to develop our cultural heritage on the basis of its essence. In this thesis, we suggest a new Satba and it’s holding before the match about the commonly called "the struggle of the Satba", argumented much during the match, to be part of the rational and systematic theory establishment. This study is based on the ground of the questionnaire to the athletes enlisted on the folk Ssirum committee. The content is summarized as follows. First, the folk Ssirum committee makes and controls a pair of the blue and red personal Satba for the enlisted athletes only, marks an athlet’s name according to the personal one, and draws a red line on the blue Satba and a blue one on the red by 1.5㎝ wide at the central line of the on left and right femoral region to clearly indicate the position of both athlet’s holding the Satba before the match. Secondly, when the committee enlists an athlete, he makes d Satba after weighing. And its size is by 114㎝ wide and 134㎝ plus the girth of the waist and the thigh long. Thirdly, they made a Satba suitable measuring its size, but they supplement its size in changing of the body class and reweighing per a quiter of half a year. Fourthly, the vice-umpire confirms to agree on athlete and its name specified on the Satba, and to agree the geight of th Satba and its line position to the central line of the left-right femoral region at the commence of the match, Fifthly, when holding Satba before the match, an athlete catches the thigh Satba first and the waist Satba next at the present practice, but he holdes the latter toward the abdomen first and the former next by the reverse order. Sixthly, when they finished all the matchs, the committee treturn and take charge of the Satba which are supplied to the atnlete after the match. In doing so, we could reduce psychological and practical fators caused by holding the Satba before the match, and enhance its value and import as a cultural heritage well-matched the aspect of the professionalized game an meeting the times. Also, we want to summarize the function of the Satba and its value as a symbolic meaning to do so, we think that it is possible to assciate the symbolic significance of our Taekeuk frag design and Jisinbalgi in the New Year manners with the Ssirum match. First, the circle of the Taekeuk frag design symbolizes the universe, which is equal to the circle in an arena. The blue and re line within the circle runs toward up and down, which symbolizes the meaning that winner or loser can be repeated and a permanent winner and loser can’t exist, I think. Also, the blue and red color is consistant with the same color Satba, which represents the harmony of power and skill. Second, the Jinsinbalgi among our New Year customs represents of expelling the minor demos to step down the chilliness of the earth. In this respect, the earth symbolizes the Yin as arena. We could understand the man and the man, doing Ssirum on it, as the Yang and the harmony of the Yin and the Yang. Therefore, we could have the significance when Ssirum makes a decision of the win or lose and it is conistent with the symbolic meaning of combination and symmetry as our proper naional sport. As mentioned above, we make an effort to proceed the practical game systematizing the size and control of Satba. We could enhance the value of our proper folk Ssirum if we had the correspondence between the Ssirum match the symbolic meaning of the Satba color.
