  • Granular cell tumor(myoblastoma) of the bronchus is an uncommon benign tumor that causes pulmonary complications due to obstruction of the airways. The tumor as origianally described by Abrikossoff was considered to be muscular origin, but currently neural derivation is favored. We report a case of granular cell tumor of bronchus of 27-year-old female patient with recurrent pneumonia that is confirmed by bronchoscopic biopsy, and review the liturature.

  • Purpose: Urgent diagnosis and treatment of the septic arthritis is required. The purpose of this study is to review to correlate preoperative MRI findings with arthroscopic findings in septic arthritis of the glenohumeral joint. Materials and Methods: Eleven patients with acute septic arthritis of the glenohumeral joint were treated with combination of arthroscopic lavage, debridement, and systemic antibiotics. The arthroscopic staging of infection was made based on the modified criteria of $G\"{a}chter$ and five major findings of MRI were marked in each stage of septic shoulder. Results: Bone and cartilage erosion was the end stage finding and two patients with all five positive findings had failed with arthroscopic treatment. Reactive bone marrow edema was evident in the greater tuberosity. Joint effusion, synovial thickening and soft tissue edema were rather non-specific finding and presented in all stages of septic shoulder. Conclusion: Diffuse marrow edema with metaphyseal cyst formation in the preoperative MRI implied advanced stage of septic arthritis, which may fail with arthroscopic debridement.

  • Recently sports science is various attempts to improve the athletes' performances. Above all they collect a results for the data and analyze the movement of the players after the game. Based on this, they are utilized to complement the vulnerability and how to improve. However, this way is not able to understand the movement a player and the flow of the game in real time. Because they are analyzed to match results based on the data. Therefore it is possible to managed for performance enhancement used to IT technology during the game in real-time.

  • Motor intentional disorders have been studied by visual examination methods such as cross-response task and Luria loop. To provide more analytical, quantitative information for motor intentional disorders, the present study developed a method which evaluates force control capabilities by the index finger. The assessment method analyzes the finger force control capabilities at four stages(initiation, development, maintenance, and termination) with NK Pinch-GripTM(force resolution= 0.098 N; temporal resolution=50Hz). By applying the assessment method, a patient(age=66) with callosal legion was compared with 6 healthy males(mean age=65.5, SD=2.8), showing significant but different decreases in force control capabilities depending on hand and response location. The assessment method would be of use to better understand various aspects of motor intentional disorders such as the effects of the disorders to the neurological network of the brain and severity assessment of the disorders.

  • Hepatoprotective effects of the water extract of Protaetia brevitarsis larva (PB) was investigated in carbon tetrachloride ($CCI_{4}$) treated male Sprague-Dawley rats. PB administration protected rats against ALT, AST and LDH elevations induced by $CCI_{4}$, as well as the severity of liver damage. PB recovered the decrease in serum level of high-density lipoprotein-cholesterol and the increase in serum level of low-density lipoprotein-cholesterol induced by $CCI_{4}$. In histopathological observation, massive fatty change and necrosis in the centrilobular area, degenerative change including pyknosis of nucleus and swelling of parenchymal cell induced by $CCI_{4}$ were clearly protected by PB. These histopathological findings paralleled with the serum biochemical results. The present results demonstrated that the water extract of PB may have the hepatoprotective effect against $CCI_{4}$-induced liver damage in vivo.

  • To gain insight on cheese consumption and develop strategies for the cheese industry, we conducted a survey of 742 women (age 25 or older) who were responsible for purchasing food for their families. Of them, 49.5% consumed cheese more than once a week and 25.1% expected that the cheese consumption of their families would increase, whereas only 7.1% expected a decrease in consumption. The most important considerations for purchasing cheese were taste and price. Of the respondents, 40.6% purchased domestic cheese, whereas 49.1% were unconcerned about the country of origin. Of them, 20.6% had experience of purchasing farm-made cheese, and 62.7% of them were satisfied with the cheese. These results suggest that cheese consumption will increase in the future, and that with attention to quality improvement and advertising, domestic farm-made cheese consumption could increase accordingly.

  • This survey was carried out to provide a sound and a vibration level of bridges on the Han river. A sound and a vibration level of 6 bridges(Ban po, Cheon ho, Olympic, Jam soo, Young dong, Dong ho) were measured. The X-axis vibration level($L_{10}$) was $42{\sim}60$ dB(H), Y-axis vibration level was $41{\sim}52$ dB(H) and Z-axis vibration level was $44{\sim}77$ dB(V). The Z-axis vibration level($L_{10}$) on the midpoint of bridges was 68 dB(V), and on the joint point was 56 dB(V). The sound level was $77{\sim}84$ dB(A). The sound level of Jam soo bridge was higher than any other bridges.

  • The molten carbonate fuel cell (MCFC) is endowed with the high potential especially in future electric power generation industry by its own outstanding characteristics. KEPCO (KEPRI) started a 100 kW MCFC system development program in 1993 and has been executed 100kW system develpilot plant successfully completed first phaseopment by 2005 on the basis of successful results of 25kW system development. In this program, the components and mechanical structure for 100 kW stack and system construction were completed on last year and now system pre - commissioning was being executed. A 100 kW MCFC power plant was constructed at the site of Boryeong Thermal Power Plant. A 100 kW MCFC system has characterized as a high pressure operation mode, CO2 recycle, and externally reforming power generation system. The 100 kW MCFC system consisted with stacks which was made by two 50 kW sub-stacks, 90 cells with 6,000 cm2 active area and BOP including a reformer, a recycle blower, a catalytic burner, an inverter, and etc. The system has been operated from 13th of September on this year and produced 50 kW AC under atmospheric pressure condition and expected to operate by the end of this year.

  • 무선 모바일 통신 시장의 성장에 따라 수동 소자로 구성된 모듈에 대한 관심이 높아지고 있다. 본 논문에서는 수동소자를 이용한 Wi-MAX용 트리플렉서를 설계하였다. 트리플렉서는 Wi-MAX의 RF Front-end단 앞부분에 연결되며, IEEE 802.16에 따른 2GHz, 3GHz, 5GHz 대역을 선택, 분리해주는 역할을 한다. 제안된 트리플렉서는 저역통과필터, 대역통과필터, 고역통과필터로 구성하였으며, 수동소자의 최소화로 인해 삽입손실 향상을 중점으로 설계하였다. 회로해석 결과, 각 대역별 (2/3/5GHz) 삽입손실은 각각 -0.5dB, -0.6dB, -0.4dB 였으며, 반사손실은 -20dB, -20dB, -12dB, 격리도는 -20dB, -24dB, -25dB의 특성을 보였다. 수동 소자의 최소화 설계로 인해 모듈 및 시스템의 저가화를 기대할 수 있다.

  • Some analogs and their Mannich bases of Antineoplaston A10 (A10) were synthesized. Chemical yield for the 2-(or 3-)thienyl, benzol, and phenylpropionyl analogs were high but 1-naphthyl analog was synthesized in low yield. The Mannich bases formation of these analogs with morpholine went verywell compared to other bases. 1-Naphthyl, 4-nitrobenzoyl, and phenylpropionyl analogs of A10 showed weak in vitro activity but the other A10 analogs showed weaker or no activity at 10-1000mcg/ml. But their Mannich bases containing A10analogs showed good in vitro activity compared to simple A10 analogs.
