Pelvic fractures are associated with life-threatening injuries and high rates of morbidity and mortality. Management of internal blood loss associated with unstable pelvic ring injuries is paramount during the initial period. The reconstruction of the pelvic ring is of importance because it is a major contributor to the stability of the pelvic ring. We report the case of a 25-year-old man who had an unstable pelvic ring fracture combined with rupture of an obturator artery and had a successful and satisfactory treatment using minimally invasive surgery with percutaneous antegrade screw fixation.

Epidural hematoma (EDH) can sometimes be life-threatening, although small-volume EDHs can resolve spontaneously like other intracranial hematomas. However, in rare cases, EDH can transform into a chronic form instead of disappearing. In contrast to subdural hematoma, there is no agreed-upon definition or treatment of chronic EDH. A 41-year-old male patient with acute EDH in the bilateral paravertical area due to partial rupture of the sagittal sinus was operated first, and then remnant contralateral hematoma was treated conservatively. One month after surgery, he showed hemiparesis, and brain imaging revealed chronic EDH at the location of the remnant acute hematoma. We performed surgery again to treat chronic EDH through a large craniotomy. Although many cases of EDH are self-limited, clinicians must keep in mind that some cases of EDH, especially those of venous origin and arising in young people, can become chronic and require surgical treatment.

Fungal thrombophlebitis of the central vein is a rare, life-threatening disease associated with significant morbidity and mortality. It requires immediate central venous catheter removal and intravenous antifungal therapy, combined in some cases with either anticoagulation or aggressive surgical debridement. A 70-year-old male patient injured by a falling object weighing 1,000 kg was transferred to our hospital. A contained rupture of the abdominal aorta with retroperitoneal hematoma was treated with primary aortic repair, and a small bowel perforation with mesenteric laceration was treated with resection and anastomosis. After a computed tomography scan, the patient was diagnosed with thrombophlebitis of the left internal jugular vein and brachiocephalic vein. Despite antifungal treatment, fever and candidemia persisted. Therefore, emergency debridement and thrombectomy were performed. After the operation, the patient was treated with an oral antifungal agent and direct oral anticoagulants. During a 1-year follow-up, no signs of candidemia relapse were observed. There is no optimal timing of surgical treatment for relapsed fungal central thrombophlebitis. Surgical treatment should be considered for early recovery.

Aneurysmal venous dilatation is a frequent complication of arterio venous fistulas (AVFs) created for hemodialysis. Venous aneurysm rupture can lead to lethal hemorrhage. A 49-year-old male patient presented with a giant aneurysmal dilatation of his AVF 10 years after its creation. The patient had complaints of pulsating pain and discomfort due to swelling of the left forearm. We performed an aneurysm resection and revised the overlying dermal lesion through a brachial plexus block. Here, we describe the pathological features of the arterialized venous aneurysm compared to simple venous aneurysms.

Architecture is the product of a way of thinking. If the problems of architecture are to be traced to their roots, then attention needs to be focused on the thinking and considerations that inform its production. Adolf Loos occupies a truly exceptional place in the history of architecture. Adolf Loos's ideas and attitudes disagree with the notion that modernity is possible to develop a harmonious culture within the bounds of a modernizing society. Loos chronologically precedes the modern movement, but his ideas contain the seeds of what will be worked out later as a complex critique of the movement's notions about architecture and modernity. Loos holds the view that modernity provokes an inevitable rupture with tradition that has as a consequence the disintegration of one's experience of life. This evolution, he think, obliges architecture to display a number of languages corresponding to a multitude of different experiences. Through the discussion of Loos's opinions on dwelling and architecture, it explores the true features of position of Loos in modern architecture. Loos thinks that the rejection of the deliberate creation of a new style was a correct response to the diagnosis of life as being rootless and fragmented. Ornament is that which people use to attempt to relate different aspects of life and to join inner and outer worlds in a coherent whole. By getting rid of ornament the illusion is destroyed that a harmonious unity of this sort is still possible. One can only remain true to tradition if one acknowledges that its continuity is not an unbroken one. Dwelling can only be saved by separating it from other aspects of life.

Objective : The aim of this study was to compare clinical characteristics of ruptured aneurysms in young adults, of the third and fourth decades of life, and to compare several clinical characteristics affecting the outcome of patients. Methods : We retrospectively investigated 1459 patients who underwent surgery and endovascular treatment for ruptured cerebral aneurysms from June 1992 to December 2010 and compared clinical characteristics. We also reviewed pre-existing medical conditions and perioperative complications. Results : Among 1459 patients, there were 21 patients (1.44%) in the third decade and 104 patients (7.13%) in the fourth decade of life. Within two age groups, 88 (70.4%) were male and 37 (29.6%) were female, a ratio of 2.37 : 1. In both groups, we observed the anterior cerebral artery (ACA) aneurysm with the most frequency (p=0.028). In general, favorable outcome was achieved in both age groups (90.5% and 81.7%, respectively). An initial univariate analysis showed Hunt-Hess grade, Fisher grade, location of aneurysm, and rebleeding significantly associated with outcome after aneurysm rupture. Further, multivariate analysis demonstrated that only Hunt-Hess grade (grade 4-5) was a risk factor for the outcome (odds ratio=9.730, 95% confidence interval 2.069-45.756, p=0.004). Conclusion : The incidence of subarachnoid hemorrhage (SAH) was higher in the male population of the third and fourth decades of life. Aneurysms on the ACA were most frequently occurred in both age groups and the outcome of aneurysmal SAH among the third and fourth decades was favorable. Multivariate analysis revealed that high Hunt-Hess grade was a risk factor for patient's outcome.

이 연구에서는 선행연구의 녹차-목재섬유 복합보드에 부가하여, 목제품 생산 후 발생하는 부산물인 편백 톱밥의 효율적인 이용과 건축내장재로의 응용을 목표로 목재섬유와 편백톱밥 및 녹차분말을 혼합한 복합보드를 제조하여 정적 휨강도성능에 영향하는 톱밥 및 녹차의 배합비율의 영향을 조사하였다. 목재섬유-톱밥-녹차 복합보드의 휨 탄성계수는 0.956~1.18 GPa의 범위에 있었고, 목재섬유 : 톱밥 : 녹차의 배합비율 50 : 40 : 10에서 가장 높은 값을, 50 : 30 : 20에서 가장 낮은 값을 나타내었다. 이 값은 선행연구의 녹차-목재 섬유 복합보드보다 2.0~3.1배 낮은 값을 나타냈다. 목재섬유-톱밥-녹차 복합보드의 휨 강도는 8.99~11.5 MPa의 범위에 있었고, 구성요소의 배합비율에 따른 휨 강도의 변화는 휨 탄성계수와 같은 경향을 나타내었다. 이 값은 선행연구의 녹차-목재섬유 복합보드보다 1.9~3.5배의 낮은 값을 나타내었고, KS에 규정된 파티클보드 및 중밀도섬유판의 강도치보다 약간 낮은 값을 나타냈다. 따라서 이 복합보드를 산업화하기 위해서는 복합보드 구성요소의 배합비율의 조정, 이종재료와의 복합화 및 접착제의 전환 등으로 강도성능을 향상시킬 필요가 있을 것으로 사료된다.

본 연구는 밀도와 귤박첨가율이 다른 톱밥-귤박 파티클보드의 동적 정적탄성계수와 휨강도를 측정, 비교하여 밀도와 귤박의 첨가율이 파티클보드의 역학적 성능에 주는 영향과 동적탄성계수와 정적 휨강도 성능사이의 관계를 조사하였다. 톱밥-귤박 파티클보드의 밀도가 0.4에서 $0.6g/cm^3$로 증가할수록 휨성능은 증가하여, 밀도가 휨성능에 크게 영향하였으며, 밀도 $0.4g/cm^3$와 $0.5g/cm^3$의 톱밥-귤박 파티클보드에서 귤박의 첨가량이 증가할수록 휨성능은 감소하는 경향을 나타내었다. 톱밥-귤박 파티클보드의 동적탄성계수, 정적탄성계수 그리고 휨강도 사이에 높은 상관관계가 확인되었으며 양단 자유 휨진동시험에 의한 동적탄성계수로부터 비파괴적으로 정적 휨강도 성능의 예측이 가능할 것으로 사료되었다.

신생아의 피막하 간 혈종은 다양한 원인에 의해서 유발되는데 대부분은 출혈의 양이 적어 임상적으로 발견되기 보다는 부검시 발견되는 경우가 많다. 그러나 출혈의 양이 많아 혈종을 싸고 있는 피막이 파열되고 잇따른 출혈이 발생할 경우에는 창백, 혈관 허탈, 빈혈, 복부팽만, 저산소증, 산혈증 등의 증상을 보이므로 조기에 의심하여 정확한 진단을 내리고 적절한 수술적 치료를 실시하지 않으면 사망률이 높다. 저자들은 태변 흡입후 신생아 가사 소견을 보여 심폐소생술을 실시한 신생아에서 출생후 7일에 발현된 대량 피막하 간 혈종 파열 1례를 경험하였기에 보고하는 바이다.

본 논문은 북한 이탈주민을 대상으로 한 설문조사와 심층 면담 결과를 활용하여 북한 내 여러 경제주체들이 경제위기에 어떻게 대응해왔고 이를 통해 나타나는 다양한 경제관행들이 공간성과 어떻게 얽혀 있는지를 규명하는데 목적이 있다. 본 논문은 북한의 시장화를 경제지리학에서 최근 논의되고 있는 '길들이기' 관점에서 바라볼 필요가 있음을 주장하고자 한다. 이와 같은 관점에서 북한의 시장화를 이해할 때 우리는 시장화를 헤게모니 권력을 갖는 거대 프로젝트로서 '저편에 놓여 있는' 무엇이 아니라 공간 내 다양한 경제주체들이 일상생활의 관행을 통해 끊임없이 (재)구성하고 있는 것으로 설명할 수 있다. 경제적 위기와 파열, 경제적 주변화에 대한 경제주체의 대응전략은 경제와 비경제가 절합되어 있는 관점에서 파악할 수 있다. 구체적으로 본 논문은 일상생활의 다양한 대응전략이 경제적, 비경제적 요인들에 의해 중층결정되어 있으며 관행의 효과성은 권력관계에 따라 차별적으로 나타나고 있음을 강조한다.
