In this study, the characteristics of NOx reduction by using charge air moisturizer system were evaluated by engine performance simulation in medium speed diesel engines. The results of performance simulation were verified by experimental results of single cylinder medium speed diesel engine equipped with charge air moisturizer system. Performance simulation was carried out to evaluate charge air moisturizer system of turbocharged diesel engine, HYUNDAI HiMSEN 9H25/33 engine. Those results show 50% NOx reduction at dew point 80℃ and charge air pressure 4bar.

Pleural complication is extremely rare among the complications of lung following transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma. We report a case of hepatopleur al fistula complicated by TACE. A 50-year-old male was admitted to the hospital because of aggravation of cough and chest pain. Fifty-five days before admission, a liver abscess had developed and treated by percutaneous drainage. A hepatocellular carcinoma had been diagnosed as a cause of liver abscess. Forty-five days before admission, TACE had been performed for the hepatocellular carcinoma. Thirty days after TACE, dry cough and right pleuritic chest pain developed. After admission, serial CT scans of thorax and abdomen showed the pleural effusion containing the lipiodol from the liver through hepatopleural fistula. Chest tube insertion with a urokinase instillation was performed for the treatment of empyema caused by hepatopleural fistula. (Korean J Med 62:278- 283, 2002)

The pelvic bone fractures in children were uncommon, except for avulsion injuries in the literature and authors had 21 cases of children' s pelvic bone fracture, ranging from 1 to 15 years. The mode of injury, type of fracture, associated injuries, morbidity and mortality, and out- come were retrospectively analyzed. The majority of injuries were from automobile-pedestrian collisions (81.0%). The Torode and Zieg type IV injury had the greatest morbidity, mortality, and complications. Sixteen patients had non-orthopedic, associated injuries and fourteen required blood transfusions within initial 48 hours after injury. Two of them passed away due to hematologic unstableness. Twenty patients were managed by conservative method, except for one operative case by using of an external fixation device. This study included only 13 cases had average I year of follow-up. One acetabular dysplasia of 5 acetabular fractures was found at 12 months after injury. The nonoperative approach for the pelvic bone injury has had a satisfactory outcome in our hospital. So, authors think that if conservative methods will be properly applied, it may be one of the methods of treatment for the children s pelvic bone fracture. Even though there is no symptoms, long-term follow-up will be inevitable for checking more severe acetabular dysplasia and leg length discrepancy.
