Korea Institute of Construction Materials founded Seosan Outdoor Exposure Test Site 2005 at Korea, which is a part of Worldwide Exposure Network (WEN). To evaluate the test site along with other exposure test sites, three different types of paints have been under real time weathering conditions at three major weathering test facilities around the world. Using these test specimens several spectroscopic experiments along with physical tests have been performed. Also acceleration tests have been performed using the same paints. The correlation of weathered paints among three different test facilities and accelerated test results has been compared. From the results the reliability of Seosan Weathering Test Facility and reasonable life time prediction tests are discussed.

The aim of this report was to present a rare case of a tracheotomy site recurrence after operation and post-operative radiotherapy in head and neck squamous cell carcinoma patient. Tracheotomy site recurrence other than subglottic cancer is very rare in head and neck cancer patient. The granulation tissue around tracheotomy was a fertile "soil" for tumor cell implantation. Midline mucosal sparing block which was used to decreased acute toxicity during post-operative radiotherapy could be facilitating the tumor cell implantation. The head and neck surgeon should try every effort to reduce contamination of cancer cells during operation and consider the entire operative field should be included in post-operative radiation portals.

There are many challenges for reconstruction after intraoral tumor resection. Especially, palatomaxillary reconstruction has two primary goals: closure of the oronasal communication and re-creation of proper myomucosal function. Prosthodontic treatment using obturator and several surgical procedures are selected depending on the size and site of the defect, the difficulty of operative procedure, operation time and donor site problem. Above all, it is considered that radial forearm free flap is the first choice for palatal reconstruction. Our department introduces a novel method using tunnelized-facial artery myomucosal island flap for palatomaxillary defect reconstruction, which can successfully reduce donor-site morbidity, and duration of surgery and hospitalization.

This study was conducted to derive the regional design rainfall by the regional frequency analysis based on the regionalization of the precipitation suggested by the first report of this project. Using the L-moment ratios and Kolmogorov-Smirnov test, the underlying regional probability distribution was identified to be the Generalized extreme value distribution among applied distributions. Regional and at-site parameters of the generalized extreme value distribution were estimated by the linear combination of the probability weighted moments, L-moment. The regional and at-site analysis for the design rainfall were tested by Monte Carlo simulation. Relative root-mean-square error(RRMSE), relative bias(RBIAS) and relative reduction(RR) in RRMSE were computed and compared with those resulting from at-site Monte Carlo simulation. All show that the regional analysis procedure can substantially reduce the RRMSE, RBIAS and RR in RRMSE in the prediction of design rainfall. Consequently, optimal design rainfalls following the legions and consecutive durations were derived by the regional frequency analysis.

We report here on an uncommon case of mediastinitis that occurred after central venous catheterization. A patient with colon and jejunal cancer complained high fever, right shoulder pain, chest pain, and limited motion of the affected shoulder just 6 days after central venous catheterization. Bacterial culture of the blood, shoulder abscess, and catheter puncture site revealed methicillin-resistent staphylococcus aureus. Right upper mediastinal widening on chest film also suggested mediatinitis. Mediastiotomy and pus drainage was performed along with adequate antibiotics therapy. In this case, it seems that initially formed bacteria from the puncture site migrated to the mediastinum through the tissue plane to start the mediastinitis. Careful dressing of puncture site and correct handling of catheter is important to prevent this serious complication.

The present study was carried out to evaluate the effect of avian pox on wild bird population by investigating the avian pox infection in migratory birds of a stopover site. 3,565 birds in 116 species were examined for avian pox in migratory birds at the Heuksando island in South Korea during the spring and fall of 2011. 20 birds in 12 species were found pox-like lesions and 5 birds were diagnosed by avian pox using PCR: Pale Thrush (Turdus pallidus), Yellow-breasted Bunting (Emberiza aureola), Yellow-throated Bunting (Emberiza elegans), Rustic Bunting (Emberiza rustica), Black-faced Bunting (Emberiza spodocephala). To our knowledge, this is the first report of avian pox detected in these 5 species of the world.

Patient safety has become a growing concern in health care. The U.S. Institute of Medicine (IOM) report "To Err Is Human: Building a Safer Health System" in 1999 included estimations that medical error is the eighth leading cause of death in the United States and results in up to 100,000 deaths annually. However, many adverse events and errors occur in surgical practice. Within all kinds of surgical adverse events, wrong-side/wrong-site, wrong-procedure, and wrong-patient adverse events are the most devastating, unacceptable, and often result in litigation. Much literature claims that systems must be put in place to render it essentially impossible or at least extremely difficult for human error to cause harm to patients. Hence, this research aims to develop a prototype system based on active RFID that detects and prevents errors in the OR. To fully comprehend the operating room (OR) process, multiple rounds of on site discussions were conducted. IDEF0 models were subsequently constructed for identifying the opportunity of improvement and performing before-after analysis. Based on the analysis, the architecture of the proposed RFID-based OR system was developed. An on-site survey conducted subsequently for better understanding the hardware requirement will then be illustrated. Finally, an RFID-enhanced system based on both the proposed architecture and test results was developed for gaining better control and improving the safety level of the surgical operations.

Contrast-enhanced ultrasonography (CEUS) has been applied to evaluate parenchymal organs in human and veterinary medicine. However, to our knowledge, there is no report on the identification of active bleeding and the bleeding site in veterinary clinical patients. Herein, we describe the use of CEUS in two cases of abdominal bleeding caused by ruptured lesions with malignant abdominal tumors. One dog had a splenic hemangiosarcoma, which had metastasized to the liver; the other dog had hepatic cell carcinomas in the left hepatic lobe, which were lobectomized, and another nodule was identified in the right hepatic lobe. Immediately after the rupture of these oncogenic lesions was suspected, CEUS was performed to identify the bleeding sites. The active bleeding sites were confirmed by hyperechoic pooling signs in the arterial phase, and extravasation could be observed within the defects showing hypoechoic perfusions in the delayed phase of the CEUS. Microbubbles were also observed in the ascites; thus, CEUS could detect the presence of hemorrhage and accurately identify the bleeding site. Collectively, the study findings suggest the usefulness of CEUS in emergent situations as it enables rapid and noninvasive evaluation of bleeding points in case of active bleeding in dogs.

This study evaluated a case of trigeminal nerve stimulation during acupotomy at a site 5 pun left of GV16. The study participant was a 52-year-old male suffering from upper neck pain and numbness, which was managed by acupotomy at a site 5 pun left of GV16. During acupotomy, the patient experienced unexpected numbness and stiffness of the left zygomatic bone. This area corresponds to the distribution of the maxillary nerve, which is the second branch of the trigeminal nerve. After approximately one month, symptoms of numbness and stiffness disappeared without rendering medical treatment. These side effects are presumed to be associated with the trigeminocervical complex and stimulation of the trigeminal nucleus within the spinal cord. Thus, during the acupotomy of the upper neck, especially at GV16, the needles should be inserted slowly, and the patient's response should also be monitored.
