오래 전부터 교정진단 및 치료계획 수립 시 골격 및 치열 관계와 안모를 분석하기 위한 필수적인 진단 자료로 측모 두부방사선계측사진을 이용하였다. 하지만 최근 들어 심미적인 측면이 강조되면서 좀 더 정량화된 연조직 분석법이 필요하게 되었고 좀 더 사실적인 연조직 측모를 얻기 위해서는 측모 두부방사선계측사진보다는 측모 사진이 더 유용할 것이다. 아직까지 측모 사진을 계측, 분석하는 경우는 드물었기 때문에 이 연구에서는 측모 사진의 계측 분석을 측모 두부방사선계측사진 분석과 비교해 봄으로써 연조직과 경조직 분석이 서로 상관관계를 갖는지를 알아보고 그 대체 가능성을 시험 평가해 보고자 하였다. 교정과에 내원한 환자들 중 측모 두부방사선계측사진의 계측치인 ANB를 기준으로 Ⅰ급 부정교합(0˚~4°) 32명, Ⅱ급 부정교합(4°≤) 32명, Ⅲ급 부정교합(5°~0°) 31명을 선정하였다. 각 피험자들의 측모 두부방사선계측사진과 측모 사진을 각각 촬영하여 수평적, 수직적 계측 항목을 설정한 후 각 계측치들의 평균과 표준편차를 구하였고 통계적 유의성을 알아보기 위해 표준화 변수 Z를 이용한 t-test와 상관분석을 이용하였다. 분석 결과 측모 두부방사선계측사진 분석에서 세 그룹 간에 뚜렷한 차이를 보이는 계측치들이 측모 사진에서도 유사한 차이를 보이는 것을 확인할 수 있었다. 본 연구결과 측모사진은 Sn-N'-Pg'은 측모 두부방사선계측사진에서 상,하악골의 전후방적인 관계를 나타내는 ANB를 대신하여 사용될 수 있으며, 측모 사진의 N'-Sn/Sn-Pg'은 측모 두부방사선계측사진의 NA/APg (ficial convexity)을, 그리고 측모 사진의 N'-Tra-Me'는 측모 두부방사선계측사진의 FH-MP (mandibular plane)을 대신하여 사용될 수 있을 것으로 보인다. Alalysis of lateral cephalometric radiograph (cephalogram) has been used routinely to evaluate skeletal and dental relationships, but alalysis of the lateral facial photograph has not been used frequently for evaluation of skeletal relationships. As concerns about harm of X-ray irradiation increases, this study was planned to evaluate the possibility of substituting analysis of the lateral cephalogram with analysis of the lateral facial photograph by comparing these two analysis. According to the ANB values from cephalometric analysis, subjects were divided into three group: ClassⅠmalocclusion group (n = 32). Class Ⅱ malocclusion group (n = 32), and Class Ⅲ malocclusion group (n = 31). After measurements of angles indicating horizontal and vertical relationships of the maxilla and mandible on the lateral cephalograms and photographs, differences between ClassⅠ,Ⅱ and Ⅲ groups were evaluated. To evaluate the similarity between two similar values in the cephalograms and photographs, t-test using standardized variable Z and correlation analysis were performed in the Class Ⅰmalocclusion group. The results show that 1) SnN'Pg' on the photograph can be used to evaluate the antero-posterior relationship of the maxilla and mandible (ANB), 2) N'-Sn/Sn-Pg' on the photograph can be used to evaluate facial convexity (NA/APg), 3) Sn-Tra-Me' on the photograph can be used as a measurement similar to FMA, In conclusion, partly substituting lateral cephalogram analysis with lateral facial photograph analysis was possible in the evaluation of the maxilla and mandible.

The purpose of this study is to measure and analyse the geomagnetic flux density distribution in a steel-concrete campus building with a flux-gate equipment referring to records. Also this study provides fundamental information and data relating to the geometric flux density in steel concrete building. The major conclusions that drawn from this study are as follows: 1)Geomagnetic flux density distribution of each measuring heights show that the closer to the floor, the more unstable and the farther from the floor, the more stable. 2)Geomagnetic flux density distribution according to the horizontal location show that a steel-concrete post makes unstable geomagnetic flux density. 3)A symmetrical floor plan does not make symmetrical geomagnetic flux density distribution.

Azithromycin으로 치료한 임신 중 쓰쓰가무시병 1예

We report a case of tsutsugamushi disease in a 26 year-old pregnant woman who was treated with azithromycin. Her gestation period was 27 weeks and she admitted with fever, rash, and eschar on the right shoulder. Currently recommended medications for the treatment of scrub typhus are doxycycline or chloramphenicol. But, these drugs are class D drugs according to the U.S. Food and Drug Administration (FDA) Fetal Risk Summary, so they couldn't be used to treat pregnant women. Recently, a few case reports suggested that azithromycin, a relatively new macrolide antibiotic, was effective and safe for the treatment of scrub typhus in pregnant women. And, there is no evidence that azithromycin causes harmful effects to the developing fetus or to children. On the basis of current in vivo test that confirms the effectiveness of azithromycin, it may be the drug of choice for the treatment of scrub typhus in pregnant women and children.

변연융선평면을 계측기준으로 한 정상교합자의 구치부 치관경사도에 관한 연구

임성훈,윤영주,김광원 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.5

이전의 preadjusted appliance 개발을 위한 치관경사도의 계측에 있어서는 교합평면을 계측기준으로 사용했는데, 교합평면은 Spee 만곡으로 인해 브라켓 부착점들을 연결하는 선(Andrews' plane)에 평행하지 않은 문제점이 있었다. 따라서 본 연구에서는 Spee 만곡에 영향받지 않으며, Andrews' plane에 보다 평행한 계측기준으로 각각의 구치의 근, 원심측 변연융선을 잇는 가상선을 설정하고, 이를 변영융선평면으로 명명하였다. 교합평면과 변연융선평면으로부터 각각 정상교합자의 구치부 치관경사도를 계측하여 비교한 결과 교합평면을 기준으로 한 치관경사도가 특히 상, 하악 제 1소구치(P<0.05) 및 제 2대구치(P<0.01)에서 Spee 만곡의 영향을 받음을 발견하였다. 구치부 치아들의 치관경사도는 Spee 만곡의 양에 따라 변해야만 인접치간 변연융선의 불일치가 생기지 않는다. 이전의 연구들에서는 다소의 Spee 만곡을 갖는 정상교합자 표본에서 교합평면을 기준으로 계측한 치관경사도를 Spee 만곡이 없는 교합평면이 치료 목표의 일부인 bracket system에 적용하는 오류가 있었다. 이러한 치관경사도와 Spee 만곡 사이의 부조화는 Spee 만곡이 straight wire에 의해 완전히 leveling되었을 때 변연융선 불일치를 초래할 수 있다. 이를 해결하기 위해서는 구치부 브라켓 slot이 변연융선평면에 평행하도록 브라켓 경사도를 결정하는 것이 추천된다. In the previous studies about prescription of preadjusted appliance, occlusal plane was used as a reference plane for crown angulation (tip) measurement. But this reference plane is not parallel to the line connecting the facial axis points at which the centers of brackets are positioned (Andrews' plane), due to the curve of Spee. Therefore, we developed a new reference plane unaffected by the curve of Spee and more parallel to the Andrew's plane. It is an imaginary line connecting mesial and distal marginal ridges of each posterior tooth, and we named it 'marginal ridge plane'. In this study, crown angulations of posterior teeth or 29 normal occlusion samples were measured and measurements from both reference planes were compared. Crown angulation measurements measured from occlusal plane were different from crown angulation measurements from marginal ridge plane in the upper and lower 2nd molars (p<0.01), and 1st premolars (p<0.05). These results were analyzed as the crown angulation measurements from occusal plane were affected by the curve of Spee. Crown angulations should be varied according to the amount of curve of Spee to maintain the continuity of marginal ridges. To solve this problem, determining bracket angulation as the bracket slot is parallel to the marginal ridge plane of each posterior teeth is recommended.

김상훈,최광돈 한국경영과학회 2001 韓國經營科學會誌 Vol.26 No.4

The purpose of this study is to derive critical success factor for ERP system implementation by integrating managerial, technical, human resource and organizational culture factors which have been proposed as influencing factors for the performance of ERP system implementation in previous studies. Especially, this study divides ERP system implementation process into preparation stage. Implement stage and settle-down and stabilization stage, and then derives critical success factors in each stage. The data for empirical analysis of the research model are collected from 64 companies and the respondents for questionnaire consist of ERP system implementation project managers and user department managers in companies which have already operated it after ERP system installation. The main results of this study are as follows. First, it derives 27 success factors through comprehensive review of various factors which may affect ERP system implementation performance, and categorizes them into one of three stages: preparation stage, implement stage, and settle-down and stabilization stage. Second, the relationship between many success factors at each stage (preparation stage, implement stage, and settle-down and stabilization stage) and performance variables is tested. As a result, the significant correlations between many success factors at each stage and ERP system implementation performance are found, and the difference among success factors in the degree of influencing the system performance is significantly shown. Finally, the relationship between process-oriented performance variables and result-oriented performance ones is tested. As a result, it is found that there is significant correlation between process-oriented performance variables except for one variable - project resource management appropriateness - and result-oriented performance ones. The theoretical contribution of this study is to derive a comprehensive model of critical success factors for implementing ERP system project from the system development life cycle perspective, and empirically test it through field survey with a wide range of data collection. And, the practical implication of this study is to present the desirable guidelines for performing ERP system implementation project successfully.

Ohjective : The primary purpose of this study was a replication of the effectiveness and tolerability of rispehdone in the treatment of patients with acute mania in very larger cohon in naturalistic treatment setting to extend the data on the effect and tolerability of risperidone in the treatment of patients with acute mania to Asian population. Methods : A total of 909 patients with DSM-TV criteria of bipolar disorder current manic and hypomanic episode, entered this large, open, multicentre study. The Young Mania Rating Scale (YMRS), Clinical Global Impression (CGI) and Simpson-Angus Rating Scale (SARS) were measured at baseline and weeks 1, 3 and 6, for the assessment of effectiveness and extra-pyramidal symptom (EPS). Results : This study showed statistically significant reduction of scores on the YMRS and CGI-s (mean change=-23.5±11.8, p<0.0001 ; mean change=-2.7±1.5, p<0.0001, respectively) from the baseline to the endpoint (week 6). Number of patients with 50% reduction or more in the YMRS and CGI-s scores was 693 (77.8%) and 630 (70.7%) at endpoint, respec-tively. There were no statistically significant increments of scores on SARS. Risperidone was generally well tolerated. Conclusion : The present larger open study demonstrates that hsperidone add-on therapy is effective and tolerable in treat-ment of bipolar disorder, replicating results in various controlled and uncontrolled studies from Western countries.
