The purpose of this was to investigate the measurement of fluence dose map for the specific patient quality assurance. The measurement of fluence map was performed using 2D matrixx detector. The absorbed dose was measured by a glass detector, Gafchromic film and ion chamber in Hybrid Optimized VMAT Phantom (HOVP). For 2D Matrixx, the results of comparison were average passing rate 85.22%+/-1.7 (RT_Target), 89.96%+/-2.15 (LT_Target) and 95.14%+/-1.18 (G4). The dose difference was 11.72%+/-0.531, -11.47%+/-0.991, 7.81%+/-0.857, -4.14%+/-0.761 at the G1, G2, G3, G4. In HOVP, the results of comparison for film were average passing rate (3%, 3 mm) 93.64%+/-3.87, 90.82%+/-0.99. We were measured an absolute dose in steep gradient area G1, G2, G3, G4 using the glass detector. The difference between the measurement and calculation are 8.3% (G1), -5.4% (G2), 6.1% (G3), 7.2% (G4). The using an Ion-chamber were an average relative dose error -1.02%+/-0.222 (Rt_target), 0.96%+/-0.294 (Lt_target). Though we need a more study using a transmission detector. However, a measurement of real-time fluence map will be predicting a dose for real-time specific patient quality assurance in volume modulated arc therapy.

Although surgical closure is the standard approach for a muscular ventricular septal defect, the procedure may be complicated by poor visualization and the need for incision on the ventricle. Another approach is catheter-based intervention. However, it also has limitations. A hybrid procedure, the intraoperative combined use of an interventional device may reduce the procedure's invasiveness. We successfully managed two cases of muscular ventricular septal defect with a hybrid procedure. We report here on these 2 cases along with a review of the literature.

OBJECTIVE: The term "Open API" has been recently in use by recent trends in social media and web 2.0. It is currently a heavily sought after solution to interconnect Web sites in a more fluid user-friendly manner. We could have many benefits easily development and high efficiency. In this paper, Real-time ambulance location monitoring system including Integrated Maps was designed by using Maps Open API based on Web 2.0. METHODS: Integrated Maps were used by using Google Maps Open API and Naver Maps Open API respectively. GPS Web Browser was implemented to present integrated Maps on the designed system continuously. The development environments of the designed systems were C# and ASP.NET Platform. RESULTS: The designed systems contained three parts composed to Integrated Maps, Ambulance System, and Center Monitoring System respectively. Integrated Maps could offer Satellite, Map and Hybrid typed maps at Real-time Ambulance Location Monitoring System. CONCLUSION: Real-time Ambulance Location Monitoring System could be developed with low cost using a Open API at available emergency situations. We expect to more using Open API in medical systems.

9.Isolation Trend of Nontuberculosis Mycobacteria at a Tertiary-care Hospital in 2003-2011.
Kosin Medical Journal 2011;26(2):155-160
OBJECTIVES: This study was performed to investigate the prevalence of nontuberculous mycobacteria (NTM) species and to determine the clinical significance of NTM isolates. METHODS: From January 2003 to July 2011, NTMs were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or reverse blot hybridization assay (REBA). And pulmonary NTM infection was diagnosed by clinical history, underlying disease, radiological and microbiological findings according to the diagnostic criteria of 2007 American Thoracic Society (ATS). RESULTS: Of the 697 AFB culture-positive specimens, NTM was detected in 149 (21.4%) specimens. Among 154 NTM isolates from 149 specimens, M. avium-intracellulare complex (MAC) (48.1%) was the most frequently isolated organisms followed by M. abscessus (13.6%), M. gordonae (9.1%), M. kansasii (8.4%), M. szulgai (3.9%), M. fortuitum complex (3.3%), M. scrofulaceum (2.0%), M. malmoense (1.3%), M. chelonae (1.3%), M. marinum (1.3%), M. genavense (1.3%), M. lentiflavum (1.3%) and M. mucogenicum (0.6%). Among 147NTM isolates from 142 respiratory specimens, 54 NTM isolates (36.7%) were causative organisms in NTM pulmonary infection. CONCLUSIONS: The isolation rate of NTM was 21.4% in clinical specimen, and in some cases NTM species results in pulmonary NTM infection. Because the treatment of pulmonary NTM infection depends on the infecting species, accurate identification and clinical significance of NTM are required for adequate treatment.

Journal of the Korean Fracture Society 2008;21(2):124-129
PURPOSE: To cmpare the clinical results of complex tibial plateau fractures treated by hybrid external fixation and dual plate fixation. MATERIALS AND METHODS: We studied forty patients with Schatzker type V and VI fractures respectively and selected twenty seven patients who were followed at least one year between January 2000 and December 2005. We evaluated the clinical results in which fourteen fractures with hybrid external fixation were compared with thirteen fractures with dual plate fixation. The clinical results were evaluated according to Knee Society Clinical Rating System and the statistical analysis was performed by Student t-test. RESULTS: There were no significant differences in terms of bone union time (average union time: dual plate fixation 13.8 weeks, hybrid external fixation 14.2 weeks). The quality of osseous reduction was superior in the fractures with dual plate fixation than those with hybrid external fixation. There were significant differences in functional score (average functional score: dual plate fixation 73, hybrid external fixation 62), but not in average knee score. CONCLUSION: The hybrid external fixation can be a useful modality for treatment of complex proximal tibial plateau fractures. But the good quality of the fracture reduction by dual plate fixation may be a indicator for favorable prognosis for satisfactory knee function.
