        이화운,김유근,정우식,오은주,임헌호,노순아,반수진,최현정,김민선,김헌숙 부산대학교 환경문제연구소 2002 環境硏究報 Vol.20 No.-

        In the view of the results investigated the effect of air pollutants that is emitted from a new generator facilities, the total estimated concentration which is the summation of a contributional concentration and observational concentration is much less than that of atmospheric environment criterion for the air pollutants. So we can predict that the operation of the new generator facilities with mitigation equipment don't seriously affect around environment. At the same time, we compared the contributional concentration of before mitigation equipment with that of after it to examine the decreasing amount due to mitigation equipment. The result showed that the concentration of SO2, NO2 and PM-10 is reduced to 25%, 30% and 26% of original value, respectively.

      • ATM 망에서의 VDT 제공 방안

        김영선,김화종,정명순 강원대학교 정보통신연구소 1997 정보통신논문지 Vol.1 No.-

        VDT was proposed in order to provide residential multimedia services such as digital video, voice, data and so on, We studied a VDT network architecture and MPEG-2 transmission scheme over an ATM network. For this purpose, we studied the network architecture and communication protocols for MPEG-2 over AAL 5. In a hierarchical video coding, a picture can be seperated into the basic and the higher layers. The basic layer coding is the minimal information needed to reconstruct the video, and the higher layer coding is used to make better quality. By simulation, we obtained the cell loss probability caused by the overflow of video traffic, when subscribers received MPEG-2 video through an ATM network.

        경기 K대학 치위생과 재학생들의 대학 진학시 학과선택 요인을 알아보고, 학과 만족도를 분석하여 치위생과 학과 경쟁력을 높이고 학생지도의 기초자료를 제공하고자 한다. 치위생과 입학 결정시 영향을 준 요인으로는 전반적으로 본인이 가장 높게 나타났으나 학년별로는 2학년이 77.5%로 가장 높았으며, 치위생과 선택이유로는 취업보장, 주위권유, 적성·흥미 순으로 조사되었다. 치위생과 학과만족도에서 강의실환경에 대해서는 전체 조사대상자 중 9.4%가 만족하다고 응답했고, 실험·실습기자재는 36.0%가 만족한다고 응답하였으며, 학우관계에서는 74.0%, 학과지도방침 38.9%, 치과위생사 직업만족도는 79.4%가 만족하고 있었다. 특히 조사대상자 중 다른 학년보다 2학년 학생들에게서 직업만족도를 제외한 다른 항목의 만족도가 가장 높게 나타나고 있다. 직업만족도는 1학년이 85.4%로 가장 높게 조사되었다. 휴학·자퇴를 고려한 경험유무에 대한 질문에서는 있다고 응답한 학생이 47.8%이었으며, 그 이유로 1학년은 경제적이유를, 2, 3학년은 적성이라고 응답하였다. 입학결정요인과 만족도와의 관계에서는 본인이 입학을 결정했을 때 재학만족도, 직업만족도, 학과지도방침, 전임교수에 만족한다고 응답한 경우가 가장 많았으며 진로계획에서는 취업이 가장 높았다. 학우관계와 만족도와의 관계에서는 학우관계에 만족한다고 응답한 경우 재학만족도, 직업만족도, 학과지도방침에 대한 만족도가 높은 것으로 분석되었다. 구강보건교육이 치위생과 선택에 미친 영향력에 대한 조사에서는 학년별 유의성은 보이지 않았으나, 전체조사대상 중 89.5%가 영향력이 보통이상이라고 응답해 높은 비율을 차지하는 것으로 나타났다. The purpose of this study is to identify the factors affecting selection of a major and the department satisfaction for improving the competitiveness of the dental hygiene department and providing the data for students guidance. The most influential person and factor in selecting a major is the person oneself(77.5% of the second-year students responded to the question) and the percentage of employment. The reaction of satisfaction with the classroom and practice facility indicates 9.4% and 36.0% in favor. 74.0% of surveyees is satisfied with classmates. In satisfaction with a course of department and profession, 38.9% and 79.4% of respondents answer in the affirmative. The second-year students of the respondents shows higher rate than other grades in .satisfaction with items above, except the satisfaction with profession. It appears that the freshman answered the most in that question. From the survey related to the experience of thinking over temporary absence from school or voluntary resignation, 47.8% of surveyees responded they had experienced thinking about that. The freshman answered the reason is financial difficulty and the second- and third-year students selected an aptitude. In the correlation coefficient of determinants for selection of college with the department satisfaction, when the determinant is oneself, the satisfaction with being at college, profession, a course of department, and teaching staff is high. In the correlation coefficient of classmates with department satisfaction, the students responding in the affirmative on classmate satisfaction had a high degree of satisfaction with being at college, profession, and a course of department. The experience of oral health education is not statically significant by grades to select the major, but 89.5% of the students majoring dental hygiene at K-college responded over average.

      • 만성 골수성 백혈병 환자에서 발생한 거대 후복막강내 혈종 1예

        박기령,김영선,박사영,최진혁,이순남,정화순 梨花女子大學校 醫科大學 醫科學硏究所 1996 EMJ (Ewha medical journal) Vol.19 No.1

        Thrombohemorrhagic complications in chronic myeloproliferative disease(CMPD) including chronic myelogenous leukemia(CML) are not rare. Lower incidence of disordered hemostasis is reported in CML compared with other CMPD. The mechanism of thrombohemorrhagic complications might be a consequence of qualitative platelet abnormalites and prolonged bleeding time rather than that of thrombocytosis. Although defect of platelet function has been extensively investigated, there was no established consistent correlation between clinical bleeding and number and function of platelet. The most common site of bleeding complications in the CMPD is superficial mucosa. Bleeding in deep tissue and viscera is very unusual. We report a case of CML which developed a huge spontaneous retroperitoneal hematoma.

        김현우,허경회,박관수,김정화,이원진,허민석,이삼선,최순철 대한구강악안면방사선학회 2006 Imaging Science in Dentistry Vol.37 No.1

        Purpose : To investigate the validity of digital image processing on panoramic radiographs in estimating bone quality before endosseous dental implant installation by correlating bone quality in radiographic images with clinical bone quality classification. Materials and Methods : An experienced surgeon assessed and classified bone quality for implant sites with tactile sensation at the time of implant placement. Including fractal dimension eighteen morphologic features of trabecular pattern were examined in each anatomical sites on panoramic radiographs. Finally bone quality of 67 implant sites were evaluated in 42 patients. Results : Pearson correlation analysis showed that three morphologic parameters had weak linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.276, -0.280, and -0.289, respectively (p<0.05). And other three morphologic parameters had obvious linear negative correlation with clinical bone quality classification showing correlation coefficients of -0.346, -0.488, and -0.343 respectively (p<0.05). Fractal dimension also had a linear correlation with clinical bone quality classification with correlation coefficients -0.506 significantly (p<0.05). Conclusion : This study suggests that fractal and morphometric analysis using digital panoramic radiographs can be used to evaluate bone quality for implant recipient sites.

        하악 제1대구치의 치근 만곡에 영향을 주는 요인

        최항문,이원진,허민석,이삼선,김정화,최순철,박태원 대한구강악안면방사선학회 2006 Imaging Science in Dentistry Vol.37 No.1

        Purpose : To find the cause of root curvature by use of panoramic and lateral cephalometric radiograph. Materials and Methods : Twenty six 1st graders whose mandibular 1st molars just emerged into the mouth were selected. Panoramic and lateral cephalometric radiograph were taken at grade 1 and 6, longitudinally. In cephalometric radio graph, mandibular plane angle, ramus-occlusal plane angle, gonial angle, and gonion-gnathion distance (Go-Gn distance) were measured. In panoramic radio graph, elongated root length and root angle were measured by means of digital subtraction radiography. Occlusal plane-tooth axis angle was measured, too. Pearson correlations were used to evaluate the relationships between root curvature and elongated length and longitudinal variations of all variables. Multiple regression equation using related variables was computed. Results : The Pearson correlation coefficient between curved angle and longitudinal variations of occlusal plane-tooth axis angle and ramus-occlusal plane angle was 0.350 and 0.401, respectively (p<0.05). There was no significant correlation between elongated root length and longitudinal variations of all variables. The resulting regression equation was Y=10.209+0.208X_(1)+0.745X_(2) (Y: root angle, X_(1): variation of occlusal plane-tooth axis angle, X_(2): variation of ramus-occlusal plane angle). Conclusion: It was suspected that the reasons of root curvature were change of tooth axis caused by contact with 2nd deciduous tooth and amount of mesial and superior movement related to change of occlusal plane.
