Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

목 적 : 본 연구는 저출생 체중아로 출생한 소아에 있어서 학동기 및 청소년기 소아 천식의 중증도에 미치는 영향에 관해서 후향적으로 검토하였다. 방 법 : 대동병원 소아과와 호흡기내과에 통원 중에 있거나 부산 동래구 및 연제구 소재 개인의원에서 대동병원으로 전원 된 천식 환자 중에서 8세 이상 18세 이하의 소아 및 청소년을 대상으로 출생체중을 기준으로 1,500 g 이상 2,500 g 미만인 15명을 추출하여 연구군으로 하고 출생체중 2,500 g 이상이며 연구군의 나이에 일치하는 순서대로 2명씩 추출하여 이 30명을 대조군으로 하였다. 결 과 : 양군을 비교한 결과 천식 중증도는 연구군에서 유의하게 높았다.(P=0.015) 또 흡입 스테로이드 약의 사용 빈도(증례군 13명/15명, 대조군 4명/30명 : P=0.0001)와 사용 기간에 있어서도 연구군에서 유의하게 높게 나왔다.(P= 0.009) 혈중 총 IgE치와 아토피피부염의 유병률은 대조군에서 높았다.(각각 P=0.007, P=0.0001) 폐기능 검사와 PC(20), 특이 IgE 항체는 두 군 사이에 유의한 결과를 볼 수가 없었다.(P>0.05) 결 론 : 천식의 중증도와 흡입 스테로이드 사용의 빈도와 기간 등으로 미루어 볼 때 저출생 체중은 소아 천식의 중증도를 증가시키는 요인 일 수 있음을 시사한다. Purpose : Over the past several decades, the survival rates of low birth weight(LBW; birth weight <2,500 g) infants have been improving. Many of these infants have had bronchial asthma(BA) at childhood and aldolescence. The aim of this study is to investigate whether LBW influenced the severity of BA in prealdolescent children and aldolescence by a retrospective case control study. Methods : 15 LBW children(1,500 g<birth weight<2,500 g) between 8 year-old and 18 year-old with BA visiting Dae-dong hospital as the case group were compared with 2 BA children to each case as the control group(total 30 children) on the basis of following criteria : the same age, he/she attended Dae-Dong hospital or local medical center after 8 years old, birth weight was more than 2,500 g. Asthma severity was modified from 2003 Guideline for management of childhood asthma at The Korean Academy of Pediatric Allergy and Respiratory Disease. PFT(Pulmonary function test) were measured using a portable spirometer. The value are expressed as percentage predicted using standard reference values. Total IgE and specific IgE Ab. were assessed by the PRIST method and MAST Allergy Test. Methacholine challenge test and PC20 was assessed by the Masterlab. Results : LBW group had : a significantly more severe symptoms between 8 year-old and 18 year-old than control group.(P=0.015) A significantly more used to ICSs(Inhaled corticosteroids) and add-on therapy than control group.(P=0.009)(P=0.0001) There were no significant differences in the PFT and PC(20) and specific IgE Ab. between LBW group and control group. But, total IgE level is higher in the control group than in the LBW group. Conclusion : These results suggest that LBW is a risk factor for the severity of BA. We suggest that infants with birth weight of less than 2,500 g have a more severe risk of asthma during prealdolescent children and aldolescence than who were birth weight of more than 2,500 g.

跳馬 Handspring 動作의 力學的 分析

李大珩,李勇仁,崔大雨 忠南大學校體育科學硏究所 1987 體育科學硏究誌 Vol.5 No.1

Mechanical analysis of the handspring motion at the long horse vault has been made as follows: 1. On setting the hands on the long horse vault, the heights of the subject body from the ground were 102cm (Subject A)and 132cm (Subject B), respectively. Subject A maintained the center of the body 30cm lower than Subject B. 2. Subject A took 0.06 seconds less than Subject B as for the time required from the feet leaving the mat to setting the hands on the long horse. 3. On taking the hands off the long horse, the power consumed was 26.88HP (Subject A)and 2.08 HP (Subject B), respectively. 4. At phase 1, the mean of HO and He was 134.76cm (Subject A), and 162.08cm and 94.96cm(Subject B), respectively. 5. The landing preparation when the neck joint is flexed was 9˚ in the frame 23(Subject A)and 176˚in the frame 31(Subject B), respectively. That means that Subject A made an earlier landing preparation than Subject B. 6. In phase 2, the mean of force was 7869.71 Newton (Subject A)and 3672.79 Newton(p<0.01)(Subject B), respecrively. That shows that Subject A consumed more force than subject B. 7. Subject A set the hands on the long horse earlier than Subject B. Subject A had the better position, when taking the hands off the horse than Subject B. On setting the hands on the horse, Subject B failed in the right landing, because the knee joint was much overflexed.

中共文化革命期에 있어서의 學生(紅衛兵)과 軍隊와의 關係

李大雨 부산대학교 통일문제연구소 1982 統一論叢 Vol.3 No.-

In this paper I shall attempt to describe real aspect of Military-Student relation during the Great Proletarian Revolution from the perspective of Mao's theory of contradiction. To achieve this aim, I shall also attempt to clarity some major concerns : interrelation between Mao's personality and political action, political turmoil and the stability of political system. As we see, Socialist Education Movement, in fact, is the strategy of conflict created by Mao Tse-tung in order to test the strength of Liuist group on the course of takeover. But it was not successful in coping with Liuist group. Mao now began to draw upon the Army's experience in coping with more extensive political difficulties, and on Lin Piao's support in his deeping conflict with the party organization. Judging from this context, it might to well assumed that Mao had already prepared to seize power in this period. This is, of course, the indication of group conflict strategy toward victory in power struggle. Mao began to turn to the new generation to attack enemy. Mao's advancing age constituted an important limit on the reassertion of his authority. However, his determination to institutionalize his own conception of new political life for China led him to seek a way of passing on the lesson of the revolution to a new generation. He was seeking a way to combine theory without relying on bookish recitations alone. At some point, before the summer or 1996 Mao conceptualized a way of confronting in "unity and struggle" both the opposition of long-time Party leaders and political immaturity of the younger generation. In the rebellion of student revolutionaries and bring them into a place of influence within China's political life. On the one hand, Mao drew upon Student Red Guard to check the PLA. But they were harmonized with each other while attacking the capitalist-roaders. Thus, Mao decided to make use of his alliance. As we have seen the outstanding contrast between Student Red Guard and bureaucrat on the one hand, and Student Red Guard and PLA on the other hand, is the reflection of the law of the unity of opposites. Student Red Guard created the PLA to use armed forces in order to check the Red Guard. The incredible turmoil of 1967 and 1968 which appears to have nearly undermined the ability of Mao and Lin Piao ride out the Luan of their to wrest political control from the party organization. Perhaps the passage of time will give a better perspective to the factional conflict and violence which appears to have brought China on the verge of Civil War. As the turmoil progressed, Mao initiated rebellion which is called 'January Storm' of Shanghai. Workers and peasants were involved in this rebellion. Finally they established Shanghais Commune. This led to another political chaos. When Mao confronted confusion, he had lost the stability of mind. However, Mao soon restored his balance of mind. In psychological dimension, we can find that Mao has the dualism of mind ; frustration and courage, nihilism and confidence. But Mao derived 'unity' from psychological confusion and he used to link psychological dimension with the political action. Mao regarded Luan as creative political conflict in rebuilding new political order. Mao pressed hard to purge the peoples in authority taking the capitalist road by grand alliance. In the wake of confusion, Mao's enduring concern about workers and peasants meant that he expressed his determined will to keep firmly the principle of Marxism-Leninism. As is viewed from the above mentioned, Mao took advantage of Military and student to seize power.

백혈병환자에서 Liposomal Amphotericin B로 치료된 파종성 Fusarium 감염 1예

이지연,김성범,박대원,신성희,김용현,윤소영,엄중식,최철원,정희진,김우주,김준석,김장수,이갑노 대한감염학회 2003 감염과 화학요법 Vol.35 No.5

Fusarium spp.는 사람에서 드물게 각막염, 조갑진균증, 상처나 화상부위감염 등을 유발하는 것으로 알려져 있으나 최근에는 면역저하자에서 기회감염의 원인균으로 증가하고 있는 추세이다. 면역저하자에서 파종성 감염이 있는 경우에 예후는 치명적이나, 증례가 많지 않고 진단방법이 제한되어 있어 조기 진단과 신속한 치료가 쉽지 않다. 그러나 특징적으로 피부병변의 동반이 흔하여 면역저하자에서는 피부 병변의 면밀한 관찰과 함께 Fusarium 감염을 조기에 의심하여 피부생검이나 배양을 하는 것이 진단에 도움이 되리라 생각된다. 파종성 Fusarium 감염의 치료로는 감염 부위의 국소적 외과적 절제와 전신적 항진균제의 사용이 필요하고 현재까지는 amphotericin B가 비교적 효율적인 항진균제로 알려져 있으나 면역저하자에서 이에 반응을 하지 않는 경우가 많다. 저자들은 급성골수성백혈병 환자에서 관해유도화학요법 시행 후 호중구감소상태에서 피부병변과 폐침윤이 발견되었고 피부의 중심부 궤양을 동반한 구진성 병변에서 배양검사를 통해 파종성 Fusarium 감염을 진단하였으며 liposomal amphotericin B (AmBisome )를 사용하여 성공적으로 치료한 예를 경험하여 보고하는 바이다. Fusarium spp., basically a superficial pathogen, is a newly emerging fungal pathogen of opportunistic infections in immunocompromised patients. At present, although Fusarium spp. are relatively resistant to amphotericin B, the combination of amphotericin B and surgical debridement appear to be optimal treatment for disseminated infection. Recently we experienced a 32-year-old neutropenic patient after induction chemotherapy for acute myelocytic leukemia presented with skin lesions and infiltrations in both lungs. We diagnosed with disseminated fusariosis by skin culture and successfully treated the patient with liposomal amphotericin B. We emphasize a high index of suspicion for skin lesions especially in immunocopromised patients.
