Remote laser beam welding (RLW) has the benefits of high speed and high quality welding, especially as applied to automotive industry. RLW is designed in a way that end effecter and head of scanner move simultaneously, and require the compensation for the motion of end effecter in order to weld proper position. In this paper, we show the algorithms of RLW that enable the end effecter to synchronize with scanner based on time. The proposed method consists of two algorithms. These algorithms make it possible for the moving end effecter to weld on desired place. The effectiveness of the algorithms is shown by experiments. 원격레이저 용접은(RLW)은 고속으로 고품질의 용접을 가능하게 하고 특히 자동차산업에 적용할 때 그 장점이 발휘된다. RLW은 로봇의 말단과 스캐너가 동시에 움직이도록 설계되는데 적합한 위치에 용접을 하기 위해서는 말단의 움직임에 대한 보상이 이루어져야 한다. 본 논문에서는 스캐너와 말단을 시간에 기반하여 동기화 하는 RLW을 위한 알고리즘을 보인다. 제안된 알고리즘은 두 개의 알고리즘으로 구성되어 있고 본 알고리즘으로 움직이는 말단이 원하는 위치에 용접을 가능하게 한다. 제안된 알고리즘의 효용성은 실험을 통해 보인다.

Acute cholecystitis as a complication of malarial disease is a rare condition, especially with Plasmodium vivax infection. A 62 year-old-female was admitted via emergency room (ER) due to high fever (40.3°C) and epigastric pain. Initial abdominal ultrasound and computed tomography (CT) scan showed edematous gallbladder with stone, which suggested acute calculous cholecystitis. Emergency percutaneous transhepatic gallbladder drainage (PTGBD) was done with systemic antibiotic therapy. The clinical course, however, unusually worsened with hypotension and intensive care unit (ICU) management was done. Four days after admission multi-focal splenic infarction was developed and Plasmodium vivax infection was diagnosed afterward. The clinical symptoms and laboratory results, including fever and epigastric pain, improved dramatically after anti-malarial treatment and cholecystectomy was done. The resected gallbladder (GB) specimen shows vasculitis pattern with capillary red blood cell (RBC) engorgement, which suggests the cause of cholecystitis was due to Plasmodium vivax rather than GB stone.

저자들은 초기의 특발성 후복막강 섬유화증으로 진단받은뒤 전신의 저림 증상이 발생한 44세 남자 환자에서 신경계를 침범한 전신홍반루푸스를 새롭게 진단하였고 스테로이드 등의 약물 치료로 두 질환 모두 성공적으로 치료한 증례를 경험하였다. 특발성 후복막강 섬유화증의 소견을 보일 경우 드물지만 전신홍반루푸스를 포함한 자가면역질환에 대한 검사도 적극적으로 고려하여야 할 필요성이 있다고 판단하여 문헌 고찰과 함께 국내 첫 증례를 보고하는 바이다. Retroperitoneal fibrosis (RPF) is a rare inflammatory fibrotic condition affecting the peri-aortic retroperitoneum in which fibrosis of the surrounding tissue can encase the ureters, resulting in obstructive uropathy. RPF is generally idiopathic in nature, but may also arise in response to other conditions, such as malignancies, infections, surgery, radiotherapy, or drugs. Idiopathic RPF is commonly seen in association with various autoimmune diseases, such as autoimmune thyroiditis, autoimmune pancreatitis, rheumatoid arthritis, and systemic lupus erythematosus (SLE). Here, we describe the first case of RPF in Korea. A 44-year-old man with SLE presenting with pain in both flanks due to RPF is discussed, along with a review of the relevant literature.

본 증례는 감염성 심내막염으로 진단된 환자에서 CA-MRSA가 동정되었으며 분자형은 PVL 음성 SCCmec type IV A; the MLST ST 72; 1-4-1-8-4-4-3 MRSA clone이었다. 심내막염의 원인 병원체였던 MRSA는 지역사회가 아닌 병원에서 발생한 것으로 추정되며 vancomycin에 감수성이 있었음에도 치료 실패하여 linezolid로 변경하여 성공적으로 치료되어 문헌고찰과 함께 보고하는 바이다. The prevalence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has been increasing worldwide. In Korea, the most common genotype of CA-MRSA is the Panton-Valentine leukocidin-negative, sequence type 72 Staphylococcal cassette chromosome (SCC) mec type IV clone. However, within Korean hospitals, this strain is still not commonly reported. In this study, we describe a case of infective endocarditis caused by Panton-Valentine leukocidin-negative MRSA (ST72-SCCmec type IV A clone). Infection occurred after open reduction and internal fixation due to a right humerus fracture with cerebral hemorrhage. Initially, the patient was treated with linezolid, but with the onset of severe thrombocytopenia, the patient was switched to vancomycin therapy. (Korean J Med 2016;90:361-364)

The importance of LCC analysis has been enlarged. Also, it would be necessary to computerize LCC analysis for accurate and logical analysis of LCC. In other papers, they showed LCC analysis model but the study of database development which could be applied in LCC analysis have been undeveloped. This study showing the development of common database for the LCC analysis computerization inquires into cost breakdown structure by previous researches. Also, it makes cost breakdown structure for deriving LCC cost item. As a result, the standard of LCC analysis computerization by developing LCC DB of cost breakdown structure would be shown.
