The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

서강석,감신,박정배,이정헌,김종근,윤영국,곽경숙,이원기,우석정 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.

Pap smear were performed to 30,294 women living in the north-west of Chung-nam. The result are summarized below 1. Positive vaginal cytology was 1.09 percent. 2. 72 percents women in their 30's and 40's experienced vaginal cytology. 3. Vaginal cytology was performed at a decreasing rate as age increases. 4. Positive cytology rate is 2.42% higher than average for elderly women over the age of 65. The present date indicates that pap smear is being widely recognized to be important but they needs to be continued advocacy for pap smear.

김융성,서중배,이석재,홍장수 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.2

연구목적 . 손상 후 3주 이상 경과된 건성 추지에 대하여 tuft를 만들어 주고 신전상태에서 K-강선으로 고정하는 수술적 치료 방법의 유용성을 분석하고자 하였다. 대상 및 방범: 1997년 8월부터 2001년 3월까지 본 교실에서 건성 추지로 치료받은 예 중 손상 후부터 3주 이상 경과된 환자 11예를 대상으로 하였다. 평균 추시 기간은 7개월(3개월-9개월)이었으며, 평균 연령은 19세(2년 3개월-48세)였다. 11예 중 4예는 15세 미만의 소아였다. 수상 후 수술까지 경과된 기간은 평균 12개월(3주-7년)이었다. 우측 수부가 7예였고, 좌측은 4예였다 수지 별로는 인지가 3예, 중지가 4예, 약지가 2예, 소지가 2예였다. 모든 예에서 신전건의 절단, K-강선에 의한 원위지 관절의 고정, tuft의 형성, Roll-stitch 등의 동일한 방법을 사용하였으며, 최종 추시일에 Crawford 평가방법을 사용하여 환자를 평가하였다. 결과: Crawford의 방법을 이용한 평가 결과, 11예 중 7예(64%)가 우수(Excellent)의 결과를 보였고, 3예(27%)는 우량(Good), 1예(9%)는 양호(Fair)로 판명되었다. 즉 11예 중 1예를 제외하고는 모두, 즉 91%에서 만족스런 결과를 얻었다 우량 또는 양호의 결과를 보였던 4예의 경우 수상 후 경과된 기간이 각각 4개월, 9개월, 3년, 7년으로 수상 후 경과된 기간이 길수록 결과가 나빴다. 15세 미만의 소아 4예는 모두 우수한(Excellent) 결과를 보였고, 반면에 양호로 판정된 환자는 연령이 48세로 대상 환자 중 가장 고령이었다. 손상된 수지가 좌측이거나 우측인지 여부와 몇 번째 수지인지 여부는 결과와 무관한 것으로 보인다. 성별과도 관련성을 알 수 없었다. 결론: 손상 후 상당기간이 경과한 후에도 비교적 간단한 수술 방법에 의한 치료가 가능하였으며, 결과도 만족스러웠으나, 지나치게 오래된(손상 후 수 개월 이상이 경과한) 건성 추지의 경우, 그리고 나이가 많은 경우 예후가 좋지 않다는 사실을 알게 되었다. Purpose : The authors have attempted to analyze the effectiveness of making tuft and fixing the distal interphalangeal joint in extension with a K-wire in patients whose injured finger were left over 3 weeks without treatment for the tendinous mallet finger. Materials and Methods : Eleven fingers of eleven patients were analyzed who were treated operatively from August 1997 to March 2001. The average follow-up period was 7 months(3-9 months). The average age of the patients was 19 years(2 years 3 months-48 years) Four out of the 11 cases were children under age of 15. The average duration between injury and operation was 12 months(3 weeks-7 years) . All cases were treated by only one surgeon(Seo, JB) and with same procedure, just cutting and reattaching the extensor tendon tightly(tuft) and fixing the joint in extension. Crawford method was used for evaluating the patients. Results : Ten out of eleven patients(91%) came out to be satisfactory according to Crawford method. Excellent in 7 cases, good in 3, fair in 1, respectively. Four patients whose duration between injury and surgery seemed to be too long(4 months, 9 months, 3 years, 7 years respectively), have not showed excellent results. Excellent results were reported in all children. On the contrary, the age of the patient who had the poorest result was 48 years(the oldest in our series) Which hands or which fingers were injured seemed to have not made any differences. So as the surgery was performed earlier and the patients were younger, the results were better. Conclusion : We advocate that it is possible to treat operatively and to get good results in Patients with neglected mallet finger deformities. But it should be emphasized that the earlier the operation is performed, and the younger the patients are, the better the results are.

Purpose To compare the diagnostic performance of rectal CT with that of high-resolution rectal MRI and histopathology in assessing rectal cancer. Materials and Methods Sixty-seven patients with rectal cancer who underwent rectal CT with rectal distension using sonographic gel and high-resolution MRI were enrolled in this study. The distance from the anal verge/anorectal junction, distance to the mesorectal fascia (MRF), extramural depth (EMD), extramesorectal lymph node (LN) involvement, extramural venous invasion (EMVI), and T/N stages in rectal CT/MRI were analyzed by two gastrointestinal radiologists. The CT findings of 20 patients who underwent radical surgery without concurrent chemoradiotherapy were compared using histopathology. Interclass correlations and kappa statistics were used. Results The distance from the anal verge/anorectal junction showed an excellent intraclass correlation between CT and MRI for both reviewers. For EMD, the distance to the MRF, presence of LNs, extramesorectal LN metastasis, EMVI, T stage, and intermodality kappa or weighted kappa values between CT and MRI showed excellent agreement. Among the 20 patients who underwent radical surgery, T staging, circumferential resection margin involvement, EMVI, and LN metastasis on rectal CT showed acceptable concordance rates with histopathology. Conclusion Dedicated rectal CT may be on par with rectal MRI in providing critical information to patients with rectal cancer.

만성 하악골염, 유행성출혈, 만성 신부전 및 간 경변증을 가진 환자의 혈청중에 포함된 여러가지 종류의 유리아미노산의 정량분석을 gas-liquid chromatography (G. L. C.)로 측정하였고, 건강인들의 유리아미노산의 정량과 비교한 결과 환자의 종류에 따라서 혈청중에 포함된 유리아미노산의 양에 차이가 있음을 발견 하였다. The quantitative analysis of various kinds of free amino acids contained in blood serum of patients with chronic mandible ostities, epidermic hemorrhagic fever, chronic renal failure and liver cirrhosis were measured with the gas-liquid chromatography (G. L. C.). The results compared with the quantity of free amino acids of healthy persons. It was found that the quantity of free amino acids were differently contained in blood serum in accordance with kinds of patients.

자연이 스스로 정화할 수 없는 임계점에 도달했음을 뜻하는 환경오염에는 대기, 수질, 토양, 소음, 전파, 방사능 등 다양한 종류가 있다. 본 논문에서는 정지궤도에서 한반도 주변의 대기오염을 감시하기 위한 GEMS (Geostationary Environment Monitoring Spectrometer)의 개발과정 및 현황에 대해서 설명한다. 2013년부터 미국과 국제공동개발로 시작된 세계 최초의 정지궤도 상 환경탑재체 GEMS는 2020년 6월 현재 초기기능시험을 완료하고 궤도상시험 수행 중에 있으며, 향후 발사될 미국항공우주국의 TEMPO (Tropospheric Emissions: Monitoring of POllution) 및 유럽우주국의 Sentinel-4와 함께 정지궤도에서 전지구의 대기오염을 감시하는 중요한 역할을 수행할 것으로 기대한다. Environmental pollutions mean nature could not be purified itself because that are exceeded the critical point of self-cleaning capabilities for air, water, soil, noise, microwave, or radioactive contaminations. This paper explains development processes and current status for GEMS (Geostationary Environment Monitoring Spectrometer) which is developed to monitor air pollutions around the Korean peninsula in a geostationary orbit. The GEMS developments have been started from 2013 as an international joint development with the United States, and it is on the In Orbit Test now after successful Initial Activation and Check activities. It is expected that the GEMS will conduct the important roles for the geostationary air quality constellation with the NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) and with the ESA’s Sentenial-4 in the early 2020s.
