"D.H .Lawrence作品속에 나타나는 ""Pan Image"" 硏究"
高龍湖 陸軍士官學校 1981 한국군사학논집 Vol.21 No.-
As its title implies, this study is intended as a survey of D.H.Lawrence's Pan images in his early and later works. He used Pan's images, demons of perversity and nobility, through his novels and created his own myth with the creative energy of the universe. He showed his own vision of Life with the primitive religion of human being and tried to tell us pan-power. He said that we had lost our primitive human-relation in our most spiritual and intellectual society and he wanted to recover our ancient human-relation with the tender contact of sexes. Even though he expressed his own pan-mystery, I think it is enough to be a new way of life in our poor society.
그래핀 산화 분말을 첨가한 플렉시블 기판 솔더 접합부의 반복 굽힘 신뢰성 향상

In this study, a new approach using graphene oxide (GO) powder-composited Sn-3.0Ag-0.5Cu(in wt.%) solder paste for improving the bending reliability of solder joints between a flexible substrate and small outline package (SOP) was suggested. The GO addition slightly affected the melting temperature, however, the change in the melting temperature was not significant. Meanwhile, we observed the addition of GO could suppress IMC growth and IMC thickness of solder joint during the reflow process. Moreover, the cyclic bending test was also performed for evaluation of reliability in solder joint and we could improve the cyclic bending reliability of solder joint by adding GO powders. For 0.2 wt.% of GO added to the solder joint, the bending lifetime was increased to 20% greater than that without GO. Pull strength and ductility of the solder joint with GO were also higher than those of the joint without GO and it was assumed that this effect by adding GO could contribute to improve cyclic bending reliability of solder joint. 본 연구에서는 그래핀 산화(graphene oxide, GO) 분말 복합 Sn-3.0Ag-0.5Cu(in wt.%) 솔더페이스트를 이용한플렉시블 기판과 SOP(small outline package) 사이의 솔더 접합부의 굽힘 신뢰성 향상에 관한 새로운 접근을 제안하였다. 솔더페이스트에 GO의 첨가는 녹는점에 약간의 영향을 미치었으나 그 차이는 미미한 것으로 나타났다. 한편, GO의 첨가는 리플로우 공정 동안 솔더 접합부의 금속간화합물(intermetallic compound, IMC) 성장과 두께를 억제 할 수 있음을 확인하였다. 더욱이 접합부의 신뢰성에 미치는 영향을 살펴보고자 반복 굽힘 시험을 진행하였으며 GO 분말의 첨가로 솔더접합부의 반복 굽힘 신뢰성 향상 시킬 수 있었다. 0.2 wt.%의 GO가 첨가된 솔더 접합부의 경우 GO가 첨가되지 않은 경우에 비하여 굽힘 수명은 20% 가량 증가하는 것으로 나타났다. GO가 첨가된 경우 솔더 접합부의 인장 강도와 연성이 증가하게 나타났는데 이러한 GO 첨가에 의한 기계적 특성 향상이 솔더 접합부의 반복 굽힘 신뢰성 향상에 기여한 것으로추측된다.

Multiple leve laminectomies are a destructive procedure complicating kyphosis, anterior sub-luxation and instability of the spine in children. The surgical procedure of multiple level osteoplastic laminotomies was proposed as an alternative by Raimondi et al in 1976. The goal is preservation of the normal architecture of the spine in patients who are still developing. We have experienced a case of multiple level laminotomies(T4-T11) for removal of epidural neuroblastoma in a 3-month old baby. The technical points of surgical procedure were discussed.
파열된 흉추간판탈출증 : 증례보고 Case Report

A soft ruptured thoracic disc herniation is very rare. We have experienced a ruptured T5-6 disc herniation which was migrated into spinal canal and compressed spinal cord posteriorly. It was difficult to differentiate it from spinal cord tumor. Posterior laminectomy offers a better chance of removal than does the anterolateral or posterolateral approach this case.
