A cyst is a pathologic lesion characterized by a cavity filled with fluid, celluar products, air, or a combination of these. Dentigerous cysts were formed around the crown of unerupted teeth. The reduced enamel epithelium persists around the crown after it has formed. Proliferation of the epithelium in a fluid-filled sac may be induced by osmotic pressure. In the first decade the most frequent location is the premolar site. In each subsequent decade the largest number of cysts are in the mandibular third molar site, with the second most frequent site being the maxillary canine. The treatment of odontogenic cyst can be mostly classified into three types of cyst enucleation, marsupialization and decompression. We should consider age of patient, anatomic structure, location and size for choosing a treatment method. Advantage of cyst enucleation is fast healing, but a injury of a surrounding structure is highly. Marsupialization is conservative treatment that can reduce the damage of a adjacent structure, but it is only limited at superficial lesion. Decompression also is conservative treatment, but it has the difficulty of the oral hygiene and the troublesome of the lavage. We present the possibility that reduces the defect of decompression and cures the lesion efficiently. We report a male patient with the dentigerous cyst developed at left mandibular third molar in this study. We used the decompression for a treatment and created special appliance to treat the lesion efficiently. We report a case of the cyst treatment that is association with efficiency of decompression appliance.

The population were increased by industrialization and urbanization of the modern society and social activities of the person were rapid increased too. Subsequently the number of motor vehicle accident, sports accident and industrial accident were increased, resulting in the number of oral and maxillofacial trauma were increased. Because of the mandible relatively protruded among the facial bone, the most frequent associated oral and maxillofacial injuries was mandible fracture in the trauma center setting. A clinical study on 411 patients with mandibular fracture who visited in Department of Oral and Maxillofacial Surgery, Chun-chon Sacred Heart Hospital during 10 years(1997-2006) was done by analysing sex, age, mode, fracture site and treatment method

정밀한 다중센서 영상정합을 위한 통계적 상관성의 증대기법

김경수,이진학,나종범,Kim, Kyoung-Soo,Lee, Jin-Hak,Ra, Jong-Beom 대한전자공학회 2005 電子工學會論文誌-SP (Signal processing) Vol.42 No.4

영상정합은 동일한 장면에 대해서 서로 다른 시간 혹은 서로 다른 특성의 센서로부터 서로 다른 위치에서 얻은 영상들의 위치적 대응관계를 찾는 기법이다. 이 논문에서는 특성이 다른 적외선 센서와 광학 센서로부터 얻은 영상의 정합을 위한 새로운 알고리즘을 제안한다. 지금까지 제안된 서로 다른 특성의 영상을 위한 정합기법은 크게 특징점 기반 영상정합기법과 밝기값 기반 영상정합기법으로 구분될 수 있다. 특징점 기반의 영상정합기법은 정확하게 대응하는 특징점을 선택하는 것이 성능에 결정적인 영향을 준다 그러나 적외선 영상과 가시광선 영상에서는 특징점이 서로 같지 않은 경우가 많기 때문에 강인하지 못하다 그리고 밝기 값 기반의 정합기법에서는 정규상호정보를 유사성 척도로 사용한 영상정합기법이 가장 좋은 성능을 제공하는 것으로 알려져 있다. 그러나 정규상호정보 기반의 영상정합기법은 두 영상의 통계적 상관성이 전역적이어야 한다는 가정을 전제하는데, 적외선 영상과 가시광선 영상에서는 이를 보장하지 못하는 경우가 많아 정규상호정보를 유사성 척도로 사용하는 영상정합기법에서도 좋은 성능을 기대하기 힐들다. 따라서 이 논문에서는 적외선 영상과 가시광선 영상의 통계적 상관성의 해석에 기반한 두 단계 영상정합기법을 제안한다. 정확하고 강인한 정합을 위해서 첫 단계에서는 두 영상에서 통계적 상관성이 높은 부분을 추출하는 ESCR기법과 두 영상을 통계적 상관성이 높도록 필터링하는 ESCF기법을 수행한다. 그리고 두 번째 단계에서는 첫 단계에서의 결과 영상에 대해서 정규상호정보를 유사성 척도로 한 영상정합을 수행한다. 다양한 적외선 영상과 가시광선 영상을 이용한 실험으로부터 제안하는 두 단계 영상정합기법이 기존의 정규상호정보 기반의 영상정합기법에 비해 정확도와 강인함, 그리고 실행 속도의 측면에서 더욱 향상된 성능을 제공함을 확인하였다. Image registration is a process to establish the spatial correspondence between images of the same scene, which are acquired at different view points, at different times, or by different sensors. This paper presents a new algorithm for robust registration of the images acquired by multiple sensors having different modalities; the EO (electro-optic) and IR(infrared) ones in the paper. The two feature-based and intensity-based approaches are usually possible for image registration. In the former selection of accurate common features is crucial for high performance, but features in the EO image are often not the same as those in the R image. Hence, this approach is inadequate to register the E0/IR images. In the latter normalized mutual Information (nHr) has been widely used as a similarity measure due to its high accuracy and robustness, and NMI-based image registration methods assume that statistical correlation between two images should be global. Unfortunately, since we find out that EO and IR images don't often satisfy this assumption, registration accuracy is not high enough to apply to some applications. In this paper, we propose a two-stage NMI-based registration method based on the analysis of statistical correlation between E0/1R images. In the first stage, for robust registration, we propose two preprocessing schemes: extraction of statistically correlated regions (ESCR) and enhancement of statistical correlation by filtering (ESCF). For each image, ESCR automatically extracts the regions that are highly correlated to the corresponding regions in the other image. And ESCF adaptively filters out each image to enhance statistical correlation between them. In the second stage, two output images are registered by using NMI-based algorithm. The proposed method provides prospective results for various E0/1R sensor image pairs in terms of accuracy, robustness, and speed.

본 논문은 8비트 마이크로 컨트롤러인 8051과의 호환성을 가진 16비트 마이크로 컨트롤러의 설계 및 검증 과정에 대해서 다루고 있다. 설계 디자인의 동작을 확인하기 위해 명령어별 검증과 명령어 조합에 의해 생성된 다양한 형태의 명령어 셋을 검증했다. 또한 다양한 형태의 명령어를 보다 효율적으로 검증하기 위한 방법을 제시한다. IMA-ADPCM, SOLA 등의 응용 프로그램의 검증을 통해서 설계 디자인의 동작을 확인하였다. 최종적으로 Xilinx FPGA(XCV1000-560C)를 이용한 보드 구현을 통해서 명령어 및 응용 프로그램 등의 동작을 검증했다. 타겟 컨트롤러인 8비트 마이크로 컨트롤러, 8051과의 호환성 및 성능비교를 통해서 널리 사용 중인 8051을 대체 할 수 있고 보다 나은 성능을 발휘할 수 있다는 것을 보인다. In this paper, we study for the design and verification of a 16 bits micro controller, which is compatible with a 8 bits micro controller, 8051, widely used in the industrial fields these days. To confirm our design, we verified our design for all instruction sets and various combinational sets of them. Also we propose a new idea for the verification of various instruction sets, We verified our design through some application programs such as IMA-ADPCM, SOLA. Finally, we verified our design for all instruction sets and application programs through an application board, used Xilinx FPGA(XCVl000-560C). After the comparison our design with a 8051 for various cases, We concluded that we could substitute our design for a 8051 and our design could be operated more powerfully than a 8051.

청주시 토양 중 다이옥신 농도 및 특성

김경수(Kyoung Soo Kim),김교근(Kyeo Keun Kim) 大韓環境工學會 2009 대한환경공학회지 Vol.31 No.5

청주시 토양을 대상으로 다이옥신의 오염수준 및 특성에 대해 조사하였다. 채취된 28개 지점의 토양 중 17개 다이옥신 이성질체의 농도범위는 2.30~630.40(평균 55.42) pg/g-dry으로 검출되었으며 TEQ 농도범위는 0.002~9.79(평균 1.13) pg I-TEQ/g-dry로 조사되었다. 이들 농도는 우리나라 소각시설 주변의 농도(불검출~153.23, 평균 7.36 pg I-TEQ/g-dry)보다 매우 낮은 수준을 나타내었다. 총농도와 TEQ 농도와는 99% 신뢰구간에서 서로 상관성을 나타냈다(p값<0.001). 토지이용별 농도는 공단>녹지>주거 및 상업지>농경지의 순으로 높게 나타났다. 이성질체 조성에 있어서는 일반적으로 토양 중에서 높게 검출되는 OCDD의 비율이 23~100%(평균 59%)로 채취지점에 따라 편차가 심하였으며, PCDF/PCDD의 비율 또한 0.1~2.4(평균 0.8)로 지점에 따라 편차를 보였다. To investigate concentration and characteristics of dioxins in soil at Cheongju city, total 28 soil samples were collected. The total and I-TEQ concentration of 17 PCDDs/DFs ranged from 2.30 to 630.40 pg/g dry weight and from 0.002 to 9.79 pg I-TEQ/g dry weight with averages of 55.42 pg/g and 1.13 pg I-TEQ/g, respectively. These levels are very lower than those of around various incinerators in Korea (from n.d. to 153.23 with average value of 7.36 I-TEQ/g). The correlation between total concentration and TEQ concentration showed significant with 99% confidence interval (p-value<0.001). The TEQ concentration as land use was high as follows; industrial area>green area>residential and commercial area>farm land. In terms of congener distribution, OCDD which is highly detected in general soil samples, was predominant and showed various fraction (from 23 to 100%). The ratios of PCDF concentration against to PCDD concentration varied as samples (from 0.1 to 2.4).

The objective of this study is to investigate the distribution of PCDDs/PCDFs in Chon-Ju River. Concentration of PCDDs/PCDFs ranged from 0.105 to 1.538pgTEQ/g in fish samples, from 0.06 to 0.42pgTEQ/g in sediment samples, and ranged from 0.016 to 0.247pgTEQ/ ℓ in water samples. These levels were some high than the result of NIER(National Institute Environmental Research) that were published in March 2000. In case of isomer`s distribution, low-chlorinated compounds(especially 2378-TCDD/TCDF), 1234678-HpCDF, and OCDD were high in fish samples. The other isomers except 2378-TCDF and OCDD were not detected in water samples. Isomer`s distribution of chon-ju river was similar to that of sediment sample, but distribution of isomer in these samples were dissimilar to that of fish sample. Therefore, we found out that selective biocaccumulation of dioxin`s isomer occurred in fish samples.

Construction and maintenance of the buildings should be planned to prevent the defects in apartment houses. Therefore, defect in each process survey were analyzed by construction companies or management office, and the results are presented a follows: First, processes are roughly categorized into three groups such as construction, facilities, and electric field. The process in which most defects occurred in the construction field is followed by facilities and electricity. The total rates of defects are 71.78% in construction, 19.32% in facilities, and 8.90% in electricity. Second, the distribution rates of defects to be maintained were 20.37% in construction using wooden materials, 18.03% in floor hating, 12.79% in tiling, and 9.54% in paperhanging. The rates of defects found in facilities were 29.12% in bathing facilities, 45.64% in kitchen facilities, and 68.95% in lighting. Third, the rates of defects to be repaired were 4.37% in construction, 1.11% in facilities, and 0.14% in electricity, which show that the repair rare was very low except for construction.

This paper is introducing on a strategy of storytelling which is utilized as a core skill in developing cultural contents. The proposed storytelling method consists of three steps(planning, production, editing). The method of storytelling strategy is based on rhetoric metaphors and classifies rhetoric metaphors into three kinds of image metaphor, image personification and image simile. This thesis produced and studied 3 visual-image contents including 1 metaphor, 1 personification and 1 simile. As a result, visual-image contents can be a resonable method of the communicational act of visual-image contents with a rhetoric expression. This result will contribute to recognize the possibility of expressing visual-image contents by various figure. Recently, there are a lot of concernments on the expression by creative visual-image contents, but a theoretical study on creative idea for visual-image contents is insufficient. So, in the future, this thesis will be used for basic materials to express a creative visual-image contents, and also contribute to offering basic theories for visual-image contents study and teaching.
