A Soft x-ray microscope operates in the 'water window' wavelength region (2.3-4.4 nm), where natural contrast between carbon (protein) and oxygen (water) allows to image a biological cell. The compact soft x-ray microscope operates at λ = 2.88 nm (430 eV) and consist of liquid-nitrogen-jet-target laser-plasma x-rays source, a tandem ellipsoidal condenser mirror for sample illumination, an objective micro zone plate, and a thinned back-illuminated charge coupled device with 1,024 × 1,024 pixels. The Liquid-nitrogen-jet-target laser-plasma source was a high brightness of 1.4×10^(12) photons/pulse·sr·line. The tandem ellipsoidal condenser mirror has 15% reflectivity. The photon flux arrived at the sample is 1.29×10^(5) photons/μ㎡ The micro zone plate was used for an objective optic, and had outermost zone width of 30 nm, zone number of 667, and diameter of 80㎛, and the focal length was 835㎛. On performance test for the compact soft x-ray microscope, the 'Siemens Star' image was obtained with a 60-nm-resolution at 380 magnification and 3 minutes exposure. I also obtained images of biological samples, such as diatom and red blood cell of a mouse with 5-10 minutes exposure.

한상봉,권오원 慶北大學校 齒科大學 1992 慶北齒大論文集 Vol.9 No.1

정상교합자 남녀 각각 20명을 8세에서 16세까지 격년으로 촬영한 측모 두부 방사선 규격사진을 이용하여 상악골의 성장량과 형을 분석하여 다음과 같은 결과를 얻었다. · 각 계층항목의 남녀별, 연령별 평균치를 얻었다. · 남녀 모두 깊이 성장보다 높이 성장쪽이 성장량이 더 많았다. · 남자의 성장량이 여자보다 많았으며 특히 상악의 높이 성장에서 많았다. · 8세때는 거의 유사한 상악골 형태가 14세에서는 남자가 여자보다 후연부를 제외하고는 전반적으로 더 컸다. The primary purpose of this study was to know the longitudinal changes in the amount of growth and the form of maxilla. From the analysis of longitudinal cephalograms derived from 20 boys and 20 girls from 8 to 16 years of age with normal occlusion, the following results were obtained. 1. The author made the tables of means and standard deviations of Korean boys and girls in each item, sex & age. 2. The growth changes in the height of the maxilla were larger than those of the depth in both sexes. 3. The total amount of growth during 8 years was larger in boys than in girls, expecially in the height growth of the maxilla. 4. At the age of 8, there was no significant difference between boys and girls, but at the age of 14, the form of the maxilla became larger in boys than in girls except for the posterior margin.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperlycooked crustacea infected with the laval stage (metacercaria) of Paragonimus westermani. The most characteristic symptoms were rust-colored sputum and cough. Paragonimiasis causes pleural thickening or effusion in 48% of the patients. Pleuro-pulmonary paragonimiasis can be easily overlooked by physicians who do not suspect this disease in the differential diagnosis. Method: We compared the outcomes of 11 patients with paragonimus empyema managed either through thoracotomy or pig-tail catheter drain. These patients were confirmed by food history, clinical and radiological findings, and laboratory data. Results: The male and female ratio was 1.75 : 1, and mean age was 40.0 ± 13.5 years. AII patients had pulmonary symptoms such as cough or chest pain. Serum-ELISA for paragonimiasis were all positive (mean titer was 0.57). AII patients had pleural effusion in radiological findings( 2 patients had bilateral pleural effusion). All patients received praziquantel (75 ㎎/㎏/day for 3days). Two patients were treated with thoracotomy and nine patients were treated with pig-tail drain. Hospital stay were 14.5 days in thoracotomy group and 5.6 days in pig-tail group respectively, Conclusion: Compared to the conventional thoracotomy grouP, the patients with paragonimus empyema who received pig-tail catheters had a significantly-decreased period of drain in situ, were clinically improved earlier, and were discharged earlier.

권대근,이상한 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.1

We observed 117 orthognathic surgery cases with dentofacial deformity for 8 years from Jan. 1986 to Dec. 1993. The ratio of male female was 1 : 1.4 and the mean age was 23.0 years ranged from 16 to 35 years. The most dominant group was related to mandibular prognathism (75.0%). Surgery method were divided into 88 cases of mandible surgery, 6 cases of maxilla surgery and 23 cases of two jaw surgery. Sagittal split osteotomy were performed on 84 cases (71.8%). Rigid fixation was increased after 1989 and total percent of rigid fixation was 66%. We used autotransfusion method from 1992 to all orthognathic surgery patient. Lower lip numbness caused by Inferior alveolar nerve injury is the most common problem after operation, and it was 63 cases (53.8%) of total operation cases. In our clinic, we performed 5 cases of re-operation because of segment malaligment, condylar sag, and fixation instability.

권대근,이상한,이근호,장도근 大韓顎顔面成形再建外科學會 1994 Maxillofacial Plastic Reconstructive Surgery Vol.16 No.1

Obwegeser Ⅱ method and Rigid fixation conserving the condylar position has been performed on 5 patients with severe mandibular prognathism, and we obtained the result after the follow up study follows. 1. Obwegeser Ⅱ method is considered to move the distal segment passively when surgical correction of severe open bite correction and large amount of set back above 15mm is needed. 2. In one case that has more change of condylar position after operation, documented immediate post- operative relapse have been occurred 3. In the others that have adequate control of condylar position, passive set back and firm skeletal fixation, more functional and esthetic improvement and more post-operative stability has been achieved
