Protective Effectiveness of Inactivated Hantavirus Vaccine Against Hemorrhagic Fever With Renal Syndrome.

Abstract: As there is no effective treatment against hemorrhagic fever with renal syndrome (HFRS), the development of effective vaccine is important. An inactivated hantavirus vaccine (IHV) has been used in Korea, but there has been controversy regarding its effectiveness. We conducted a case-control study to evaluate the vaccine effectiveness (VE) of IHV against HFRS in the Korean military. Unadjusted and adjusted VEs of IHV were 59.1% and 58.9%, respectively. VE was higher in divisions with high incidence of HFRS (unadjusted VE, 71.4%; adjusted VE, 78.7%). Our study demonstrated the moderate effectiveness of IHV in high-risk populations residing in endemic area.

A Robust Control of Robotic Hand with Nine Axis for Assembly and Handling of Parts In Forging Manufacturing Process

Abstract: The focus of this paper is to design and flexible control a three fingered hand system with eight axes for smart factory with an flexible controller, and to keep a useful big database for dynamic manipulation based on the experimental results. The weight of the hand module is only 1.2 kg, but flexible motion and powerful grasping are possible. To achieve such a flexible motion control of a robotic hand, we have developed a robust and precise fingered hand with a control system incorporating image recognition system in which we deal with the problems of not only accuracy and range of motion but also the flexibility of hand. The fingers are arranged so as to grasp both circular and prismatic objects. In order to achieve the light mechanism, we reduced the number of joints and fingers as much as possible. In this study, it was used three fingers with eight axes which is the optimal number to achieve a robust grasping diverse shape parts for factory automation.

Right Main Bronchus Rupture Presenting with Pneumoperitoneum.

Abstract: We report the case of a 16-year-old male patient who was involved in a traffic accident and transferred to the emergency department with mild chest pain. We initially did not find evidence of tracheal injury on computed tomography (CT). Within an hour after presentation, the patient developed severe dyspnea and newly developed subcutaneous emphysema and pneumoperitoneum were discovered. Abdominal CT showed no intra-abdominal injury. However, destruction of the right main bronchus was identified on coronal images of the initially performed CT scan. Emergency exploratory surgery was performed. The amputated right main bronchus was identified. End-to-end tracheobronchial anastomosis was performed, and the patient recovered without any complications.
