The purpose of this study was to evaluate the accuracy and usefulness of spiral tomography through the comparison and analysis of SCANORA cross-sectional tomographs and DentaScan computed tomographic images of dry mandibles taken by a SCANORA spiral tomographic machine and a computed tomographic machine. Thirty-one dry mandibles with full or partial edentulous areas were used. To evaluate the possible effect of location in the edentulous area, it was divided into 4 regions of Me (region of mental foramen), MI (the midportion between Me and M2), M2 (the midportion between mental foramen and mandibular foramen) and S (the midportion of the mandibular symphysis). A ZPC column (sized 4 mm x 5 mm) was seated on the edentulous regions of Me, MI, M2 and S using the acrylic stent. Then SCANORA spiral tomography and computed tomography were taken on the edentulous regions which contained the ZPC column. The ZPC columns and cross-sectional images of the mandible were measured in the radiographs by three observers and the differences between the two imaging modalities were analysed. The results were as follows: 1. In comparing the actual measurements of the ZPC column and measurements in the radiographs, the mean error of the DentaScan computed tomography was 0.07 mm in vertical direction and -0.06 mm in horiwntal direction, while the mean error of the SCANORA spiral tomography was 0.06 mm in vertical direction and -0.12 mm in horizontal direction. There was a significant difference between the two radiographic techniques in the horizontal measurement of the ZPC column of the symphysis region (p<0.05). But there was no significant difference in the measurements of other regions (p>0.05). 2. In measurements of the distance from the alveolar crest to the inferior border of the mandible (H), and of the distance from the alveolar crest to the superior border of the mandibular canal (Y), there was no significant difference between the two radiographic techniques (p>0.05). 3. In measurements of the distance from the lingual border of the mandible to the buccal border of the mandible (W), and of the distance from the lingual border of the mandible to the lingual border of the mandibular canal (X), there was a significant difference between the two radiographic techniques in measurements of the midportion between the mental foramen and the mandibular foramen (M2) (p<0.05). But there were no significant differences in measurements of the other regions of symphysis (S), mental foramen (Me), the first one-fourth portion between the mental foramen and the mandibular foramen (M1) (p>0.05). 4. Considering the mean range of measurements between observers, the measurements of SCANORA spiral tomography showed higher value than those of DentaScan computed tomography, except in measurements of symphysis (S). 5. On the detectability of the mandibular canal, there was no significant difference between the two radiographic techniques (p>0.05). In conclusion, SCANORA spiral tomography demonstrated a higher interobserver variance than that of DentaScan computed tomography for implant site measurements in the posterior edentulous area of the mandible. These differences were mainly the result of difficulty in the detection of the border of the mandible in SCANORA spiral tomography. But considering the cost and the radiation exposure, SCANORA spiral tomography can be said to be a relatively good radiographic technique for implant site measurement.

1982-92 년간 근로자가구의 소득분배 변화 추세 : 소득원천별, 사회보장수혜, 이전소득, 조세부담

김기덕,손병돈 한국사회복지연구회(서울대학교 사회복지연구소) 1995 사회복지연구 Vol.6 No.1

이 연구는 82-92년간 우리나라의 소득분배형태가 어떤 변화를 보이고 있는가를 살펴보기 위하여 근로소득, 자본소득, 이전소득, 조세부담의 계층별 분배정도를 분석해 보았다. 연구 결과는 크게 세 가지로 요약된다. 첫째 총소득의 분배는 1980년대 중반이후 불평등도가 점점 완화되는 경향을 보이고 있는데, 그것은 임금 및 봉급등 근로소득의 분배에서 중하위계층의 소득이 중상위계층의 소득보다 더 급속히 증가한 경향에 기인하는 것으로 밝혀졌다. 둘째 일반적으로 시장경제의 불평등을 완화하는 것으로 평가되는 사회보장수혜는 1차소득의 불평등정도를 오히려 악화시키고 있는 것으로 분석되었다. 그리고 이전소득 중에서 사적 이전소득이 사회보장 수혜보다 훨씬 더 큰 비중을 차지하고 있으며, 사적이전의 불평등한 분배정도가 사회보장수혜의 불평등한 분배정도보다 적은 것으로 나타났다. 셋째 국가에서 실시하는 소득재분배기제 중에서 조세정책만이 우리사회의 불평등 완화에 일정정도 긍정적인 역할을 하고 있는 것으로 밝혀졌다.

주파수 성형 LQ제어기를 이용한 반능동식 자기유변유체 현가 시스템

김기덕,전도영,Kim, Gi-Deok,Jeon, Do-Yeong 대한기계학회 2000 大韓機械學會論文集A Vol.24 No.9

An MR(Magneto-Rheological) fluid damper is designed and applied to the semi-active suspension system of a 1/4 car model. The damping constant of the MR damper changes according to input current and the time delay of the damper is included in the system dynamics. The passive method, LQ control and Frequency shaped LQ control are compared in experiments. The advantage of the proposed frequency shaped LQ control is that the ride comfort improves in frequency range from 4 to 8Hz where human body is most sensitive and the driving safety improves around the resonance frequency of unsprung mass, 11Hz. The experiments using a 1/4 car model show the effectiveness of the algorithm.

고리 투영 변환과 벡터 합을 이용한 새로운 별 인식 알고리즘

김기덕,임이랑,방효충 한국항공우주학회 2014 한국항공우주학회 학술발표회 논문집 Vol.2014 No.11

본 논문에서는 새로운 별 인식 알고리즘을 제안한다. 최근에는 기존에 사용하던 CCD(Charge Coupled Device) 화상소자보다, 저 전력 및 낮은 가격과 함께 우주환경에서 높은 내구성을 지닌 CMOS(Complementary Metal Oxide Semiconductor) 화상소자를 많이 사용하는 추세이다. 그러나 CMOS 화상소자를 사용할 경우 CCD 화상소자보다 이미지의 질이 낮기 때문에 잡음에 강건한 인식 알고리즘을 필요로 한다. 잡음에 강건하기 위해서는 패턴 매칭을 이용한 별 인식 방법을 사용하는 것이 일반적이며, 패턴을 생성할 때는 직교 좌표계 보다는 극 좌표계를 이용하는 것이 더 강건하다고 알려져 있다. 본 연구에서는 고리 투영 변환과 벡터 합을 이용한 패턴으로 별을 인식하는 새로운 알고리즘을 제시하며 다양한 잡음 조건 속에서 시뮬레이션을 통해 별 인식 결과를 확인해 본다. This paper proposes new star identification algorithm. Rather than using a existing CCD image device, recently CMOS image device is used because of its high durability in space environment and low power consumption and price. However quality of CMOS image is lower than CCD image. So it is important to use an identification algorithm which is robust to noises. Identification algorithm using pattern matching is generally used for robustness to noises. Also it is noted that using polar coordinate system is more robust than Cartesian coordinate system in pattern generation. Then, this paper proposes new star identification algorithm with a pattern using ring projection transform and vector sum, and the algorithm is simulated in several noise cases.

The Apes of God의 座標 : Wyndham Lewis 小考

金基德 淑明女子大學校 1978 論文集 Vol.18 No.-

My aim in this study is to present The Apes of God as a masterpiece of a satire and external method; to demonstrate through quotation, comment and analysis significant aspects of the Apes. Although Wyndham Lewis commanded limited recognition in England and America during most of his life time, one speculates, indeed, how many Koreans are hearing his name, or at least identifying it for the first time. It is a matter of regret that there are very few persons in Korea who are intrested in Mr. Wyndham Lewis and his literature. During the thirties in which the Move ment of Modernism was prevalent in the literary circle of Korea, late Dr. Jae-Seo Choi refered to only the name of Wyndham Lewis along with T.S. Eliot, Ezra pound, I.A. Richards and Herbert Read and so on. Since then not even the name has been mentioned in both the academic and the literary circles of Korea for more than forty years. Such being the case, I have written two short treatises on Wyndham Lewis; the one was "Introduction to Wyndham Lewis", the other "A Study on Wyndham Lewis' Political Point of View", in 1970 and 1973 respectively. As a premise of the discussion, the basic conception of his satire and the great philosophy of 'eye' are commented in this study, refering to his posture as a sociological-diagnotician and a painter. His external imagery is also briefly treated in this comment. After that the general survey of The Apes is followed, as a satire of the Bloomsbury and the decadence prevalent between the two great wars. Timothy Masterer or some other commentators argues that in so far as Wyndham Lewis strives only for the spatial efforts proper to painting, he fails in The Apes. But it is no exaggeration to say that in spite of the limitation of the external method, Mr. Wyndham Lewis becomes, as T.S. Eliot says, the greatest prose master of style of his generation. The Apes of God is also an inevitable milestone in his literary pilgrimage.
