<P>This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was −0.4% (95% confidence interval, −9.8% to 9.1%), which was above the non-inferiority margin of −14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670)</P>

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

In the present study, a towed underwater particle image velocimetry (PIV) system was validated in uniform flow and used to investigate the free-surface effects on the turbulent wake of a simple surface-piercing body. The selected test model was a cylindrical geometry formed by extruding the Wigley hull's waterplane shape in the vertical direction. Due to the constraints of the two-dimensional (2D) PIV system used for the present study, the velocity field measurements were done separately for the vertical and horizontal planes. Using the measured data at several different locations, it was possible to identify the free-surface effects on the turbulent wake in terms of the mean velocity components and turbulence quantities. In order to provide an accuracy level of the data, uncertainty assessment was done following the International Towing Tank Conference standard procedure.

임베디드 소프트웨어는 그 특성상 제품의 종류가 매우 다양하고 각 제품마다 필요로 하는 기능도 아주 상이하며 제품의 하드웨어에 의존적인 소프트웨어이다. 또한 특정 CPU 에 대한 한번의 개발로는 다양한 임베디드 시스템을 지원하기가 어려우므로 최대한 하드웨어의 종류에 독립적으로 개발하면서, 빠른 시간에 각 제품에서 요구하는 기능에 최적화된 임베디드 소프트웨어를 개발하기 위한 기술이 필요하다. 본문에서는 이러한 임베디드 소프트웨어를 개발하는데 필요한 그래픽 라이브러리에 대하여 알아보고 일반적으로 리눅스 시스템에서 많이 사용되고 있으며 공개된 형식의 GTK+ 그래픽 라이브러리를 임베디드 리눅스 시스템에서도 널리 사용할 수 있도록 경량화 하는 방법에 대하여 알아본다.

자동차 내부 네트워크 데이터를 이용하는 자동차-IT 융합 기술은 자동차 안전 및 진단, 텔레매틱스, ITS등 새로운 서비스 시장을 형성하며 산업적인 파급 효과가 클 것으로 전망된다. 이러한 자동차 내부 네트워크 데이터 중 가장 최근에 많이 사용되고 있는 것이 CAN(Controller Area Network) 이다. 그리고 현실적으로 자동차 내부의 데이터 중 사용할 수 있는 가장 적절한 데이터가 Diagnostic CAN 데이터이다. 본 논문에서는 자동차-IT 융합 기술에서 사용할 수 있는 CAN 데이터 중에서 진단용 CAN데이터에 대하여 알아보고 이를 제품개발에서 사용할 수 있도록 하기 위한 데이터를 수집하고 제공하는 방법에 대하여 알아본다.

Purpose This study aims to draw a business agreement between SMEs and patent agents through the relative importance of evaluation factors for selecting patent attorneys. Methods This study designs an empirical research model to determine the relative importance of service quality evaluation items for the selection of patent attorney (PA) by small and medium-sized enterprises (SMEs). The relevant literature is reviewed by focusing on selecting or evaluating PA from companies, universities, and public organizations in South Korea at a working level. Further, interviews from experts on intellectual property (IP) are conducted and the service quality of PA is analyzed using an analytic hierarchy process (AHP). Results We find that SMEs prioritize cooperation in their supporting tasks, followed by the quality of documents, performance, IP innovative development, and IP management support. However, there are differences between public organizations and PA, even though they prioritize performance, quality of documents, human resources, and size at similar levels. Conclusion This approach is unique as it combines PA service quality for technology, law, and service in professional service firms. We expect that this study will promote innovation and outcomes for SMEs for sustainable economic growth and improve PA' quality of service.
