Mycoplasma pneumoniae infection is usually confined to the respiratory tract but it can cause a variety of extrapulmonary manifestations such as rashes, myalgia, hemolytic anemia, cerebral infarction, transverse myelitis, cerebellar ataxia, Guillain-Barre syndrome and meningoencephalitis. Neurologic complications of Mycoplasma pneumonia have been rarely reported until now. Cerebral infarction as a complication of mycoplasma infection in children has been very rarely reported. In our case, in a young girl with M. pneumoniae infection, a cerebral infarct resulted in persistent and significant neurological dysfunction. We report a 11-year-old girl with cerebral infarction associated with clinical and serologic evidence of Mycoplasma infection.

Purpose: The purpose of this study is to assess the results of the autologous osteochondral grafting for the osteochondral lesion of the talus. Materials and Methods: This study included 21 patient who had been treated with the open autologous osteochondral grafting between December, 1999 and December 2003. We treated the patients with autologous osteochondral grafting method who had the lesion of stage II or medial lesion of stage III without improvement for at least 6 months, the medial lesion of stage IV, the lateral lesion of stage III, IV by Berndt and Harty's classification or who had not improved with previous operation. The average duration of follow up was 26 (12-56) months. 6 patients had been treated with the previous operation that 3 patients with drilling, 3 patients excision, curettage and drilling. Results: The average AOFAS Ankle/Hindfoot score was 92.7 points and no patient had a limitation of the daily activities due to pain or abnormal function. Postoperative radiography showed good joint congruency and postoperative MRI good incorporation of the graft. The average Lysholm knee score was 96 points and only two patients had mild knee pain during severe exertion. Conclusion: The autologous osteochondral grafting is the useful operative method when the lesion is advanced stage or when previous operative treatment has failed.

Radioactive isotopes which are manufactured using a cyclotron in a radioisotope used for radiation diagnosis is affected by the production yield according to size and shape of the beam and beam uniform degree from irradiated location when the proton beam investigated the target by cyclotron. Therefore, in this paper developed the BPM(Beam Profile Monitor) device capable of measuring the beam cross-section at the cyclotron beam line. It was configured so as to be able to remote control the BPM device in LabView and used the BPM program it was to be able to easily monitor and display to analyze the graph of two-dimensional graph and a three-dimensional beam distribution numerical information of the beam obtained while scanning the tungsten wire to the X and Y axis. The time it takes to measure the beam can be confirmed 37seconds when step motor driving speed was 2000pps. Through a beam readjusted based on the measured beam distribution information by optimizing the beam distribution it can be made to maximize the RI production yield and contribute supply stabilization. 방사선 진단에 사용되는 방사성동위원소 중 사이클로트론을 이용해 생산되는 방사성동위원소는 사이클로트론에서 인출된 양성자 빔이 타겟에 조사될 때 빔의 크기와 모양, 조사되는 위치에서 빔 균일 정도에 따라 생산 수율에 영향을 받는다. 이에 본 논문에서는 사이클로트론 빔 라인에서 빔의 단면을 측정할 수 있는 BPM(Beam Profile Monitor)장치를 개발하였다. LabView로 BPM장치를 원격 제어할 수 있도록 구성하였으며 BPM 프로그램을 이용하여 X축과 Y축으로 텅스텐 와이어를 스캔하면서 얻은 빔의 수치 정보를 2차원 그래프와 3차원 빔 분포 그래프로 표시하여 해석을 쉽게 모니터링 할 수 있도록 하였다. 빔을 측정하는 데 걸리는 시간은 스텝 모터 구동 속도가 2000pps일 때 37초가 걸린다는 것을 확인 할 수 있었다. 측정된 빔 분포정보를 기반으로 빔 재조정을 통해 빔 분포를 최적화함으로써 방사성동위원소 생산 수율을 극대화 시킬 수 있고 공급 안정화에도 기여하리라 본다.

<Eulji Project>, the main work of this thesis, is a series of photographs focused on the changing urban space. The traces of time found in the city and the landscape created by mixing them were interpreted as artistic elements. It is composed of three series total, according to the interests of each detailed series and the method of expressing them. In this paper, focusing on the <Eulji Project>, the author looked at the process of materializing the formative elements and artistic meanings found in the urban landscape and expressing them through photography. This thesis examines and analyzes the background, main concepts, and production process of these series in detail, and studies the artistic significance of the works. It is an exploration of the author's perspective on the cycle of city space’s change, and an exploration of the disorder and unstable form revealed in the process of transitioning the existing urban space to a new urban space. As a complex attempt based on the author's exploration, expression, intervention, and interpretation, this thesis has artistic significance. This thesis was a process of reflecting the artist's perspective on a space where very complex elements of the city co-exist, and trying to present a new perspective through artistic practice.

In order to improve the refresh rate of old newspaper(ONP), PCC shape-controlling experiments were carried out. The effect of aPCC polymorph on improving the quality of old newspaper was studied for a transformation from waste paper to eco-friendly paper. The synthesis of PCC consists of an in-situ process and a loading process to enhance the refresh rate of old newspaper. Thecharacteristics between the in-situ process and the loading process could be analysed by SEM analyses of coated fiber surfaces. Theretention rate ranges from 65 to 67% after the application of the in-situ process, and that after the loading process ranges from 55 to58%. The retention rates thus show a difference of about 7-10%. In addition, the whiteness and ERIC characteristics of the in-situprocess gave more efficient results than those of the loading process.

Study Design: A Case report. Objectives: We report 4 cases of transverse fracture of upper sacrum with good clinical results. Summary of Literature Review: There is no clear guideline for the treatment of transverse fracture of upper sacrum. Materials and Methods: Four patients, who visited our institute for transverse fracture of upper sacrum, were reviewed from January 2006 to July 2009. Results: All patients had good clinical results after treatment. Conclusions: In all cases, patients were managed conservatively without reduction or internal fixation. Only for Roy-Camille type 2 and 3 transverse fracture of the upper sacrum with neurologic deficit, decompression was performed, yielding good clinical results.
