  • In this Paper, Ⅰ illustrate the continuity and severance of Korean railroad. The Korean railroad has been running for 105 years now since it started operation in 1899. Between 1905 and 1945, Japan's imperial government ruled Korea including operations of the railroad. After Korea restored its sovereignty, Korean nationals managed the Korean railroad with our own ability and strategies. At present, we can examine the effect of railroad in perspective of continuity and severance respectively. For one thing, the concept of continuity is described as influence or railroad still remains. For another, the severance shows facts and phenomena that are broken off. I have come up with some facts that are involved with continuity. For example, infrastructure and the formation of cities and land spaces are connected with the sequence. Futhermore, the railroad has made a huge dent in modernization and expedition of movement. In the course of tracing down the facts, I classified the concept of severance : the separation of South and North Korea, drastic changes in transport policy, operations and characteristics. Finally technology has brought about a major breakthrough with the development of Koran high speed rail.

  • Background: Mycotic aortic aneurysms are rare and life-threatening. Unfortunately, no established guidelines exist for the treatment of patients with mycotic aortic aneurysms. The purpose of this study was to evaluate the midterm outcomes of the open repair of mycotic thoracic and thoracoabdominal aneurysms and suggest a therapeutic strategy. Methods: From 2006 to 2016, 19 patients underwent open repair for an aortic aneurysm. All infected tissue was extensively debrided and covered with soft tissue. We recorded the clinical findings, anatomic location of the aneurysm, bacteriology results, antibiotic therapy, morbidity, and mortality for these cases. Results: The median age was $62{\pm}7.2years$ (range, 16 to 78 years), 13 patients (68%) were men, and the mean aneurysm size was $44.5{\pm}4.9mm$. The mean time from onset of illness to surgery was $14.5{\pm}2.4days$. Aortic continuity was restored in situ with a Dacron prosthesis (79%), homograft (16%), or Gore-Tex graft (5%). Soft-tissue coverage of the prosthesis was performed in 8 patients. The mean follow-up time was $43.2{\pm}11.7months$. The early mortality rate was 10.5%, and the 5-year survival rate was $74.9%{\pm}11.5%$. Conclusion: This study showed acceptable early and midterm outcomes of open repair of mycotic aneurysms. We emphasize that aggressive intraoperative debridement with soft-tissue coverage results in a high rate of success in these high-risk patients.

  • This study aimed at understanding the spatial characteristics in the Tugendhat house. For this study, it is need to analyze the early plans of the Tugendhat house design process. To analyze this, the study leads to how to effect on the real practice with the process. Therefore, this research investigates the conceptional design process of the house. There are 2 main characteristics of the interior space alternation. One is the closed spatial character on the 2nd floor, the other is the open spatial character on the 1st floor. It clearly shows the severance between interior and exterior on the 2nd floor. Each 2nd floor's space volume uses different materials so that each the space can show the individuality. On the 1st floor, however, it seems the interior is not as much open to the exterior, because the materiality and reflection of the glass, the objet of furniture and wall. In case of 1st floor, it has a complex concept as open and close character, because it is using the proper gardening elements and the relationship between the house and site. The exterior characteristic is separated the house from the ground with the podium and the slope, and this leads to have the discontinuity. The house clearly shows the spatial characteristics of the continuity and discontinuity, it proves that Mies tried to move onto modem architecture as a turning point.

  • Benign peripheral nerve tumors, although infrequent, must be considered as a possible cause of pain and disability in the extremities. There are three varieties of these tumors that are of clinical importance: neurilemmomas, neurofibromas, and post-traumatic neuroma. Neurilemmomas are the most common primary solitary tumor of the peripheral nerve trunks, and are almost always benign, Neurofibromas may occur as a solitary nerve tumor, but can present as multiple lesions as in von Recklinghausen's disease. Clinically, this tumor may presents as a solitary mass in the subcutaneous tissue which is centrally located with the nerve fibers travelling through the tumor mass. Traumatic neuroma is the proliferation of nerve elements with connective tissue during the process of regeneration from severed nerves undergoing Wallerian degeration, and is therefore not a true neoplasm. A neuroma-in-countinuity is the result of partial severance of a nerve, or of a crushing or traction injury in which all or part of the epineurium and perineurium is intact. We experienced each of the three varieties. With magnification, the neurilemmoma was removed by meticulous dissection from the parent nerve preserving the normal fascicles to which it was attached. The neurofibroma was excised and the nerve was reconstructed with interposed vein graft and the neuroma-in-continuity was excised and reconstructed with sural nerve graft. We report histologic characteristics of each tumors and the methods to repair the nerve defects after tumor excision with brief discussion.

  • 이 글에서 다루고자 하는 주요 퍼즐은 '왜 영국은 19세기 말 ~ 20세기 초 기간 동안 다른 국가와 달리 초국적기업이 출현하는 일반 구조를 발전시키지 못했는가?'이다. 이에 대해 필자는 비록 완전한 대답은 아니지만 근본적으로 영국 사회의 속성을 보여주는 '사회적 구성(Social construction)'의 맥락에서 그 원인을 규명하고자 한다. 이러한 목적 하에 이 글은 사건을 둘러싼 행위자들의 이해관계와 (사건에 대한)통제력이 빚어내는 사건의 가치 상승효과를 고려한다. 이 글의 결론은 다음과 같다: 첫째, 영국 사회 내에 팽배해 있었던 산업자본주의에 대한 경멸과 대기업 및 초국적 기업 육성의 필요성에 대한 영국 정부의 불식, 그리고 신사적 지배층의 확산과 더불어 수반된 시티의 상업-금융 자본가들의 영향력 확대 등도 영국 기업의 초국적화를 가로막았다. 둘째, 영국의 정치적 지배구조와 경제구조의 토대는 지속과 변화를 동시에 보여주었다. 1850년 이래 영국 사회구조는 점진적으로 시티의 상업-금융 자본가들의 영향력이 강화되는 구도로 형상화되었다. 그리고 그 결과는 제조업체의 초국적화가 아닌 금융서비스업의 초국적화였다. 셋째, 영국 엘리트 집단들이 주도한 사회연결망의 형상은 단절과 연계로 구분되는 행위자들의 이해관계와 통제력을 통해 구성된다. 서로의 이익이 상호보완적이었던 것과 달리 통제력의 차원에서 초기에는 지주계급과 상업-금융 자본가들의 자발적 동기에 기반 한 의도된 연계가 형성되었으나 결국 통제력의 소유는 산업자본가들을 배제한 채 상업-금융자본가들에게로 이전되어 사회연결망의 재구축이 이루어졌다.
