도용태,최병수 대구대학교 정보통신연구소 2012 情報通信硏究 Vol.9 No.1

화재는 여러 가지 재난들 중에서 가장 흔하다. 따라서 이에 대한 효과적인 대책이 필요하지만, 기존의 연기 검출기를 비롯한 단순한 형태의 센서들은 자주 오작동하는 문제가 있다. 이 문제에 대한 해결책으로 카메라의 영상을 사용하여 화재를 검출하는 방법에 대한 관심이 근래 증대되고 있다. 본 논문에서는 화염을 포함하는 영상을 검출하기 위한 기법이 서술된다. 주어진 영상을 다수의 영역으로 나눈 후, 각 영역의 특성으로부터 화염의 존재 유무를 판정한다. 서술된 기법은 다양한 영상들을 이용하여 그 성능을 평가하였으며, 그 성공률은 약 73%이었다. 이와 같은 결과는 연속 영상에 의한 화재감지에 사용되어 더 높은 성공률로 개선될 수 있을 것이다. detection using camera images. In this paper, a technique to detect images containing flames is described. After segmenting a given image into multiple regions, the existence of flames is determined from the characteristics of each region. The described technique was tested using various images, and we could get about 73% of success rate. This result may be improved by detecting fire in image sequences.

The Changes of mucosubstances in the duodenal mucosa of developing rats were investigated by conventional methods. On the 15 and 17 day-old fetal rat, neutral mucosubstances were observed in the stratified epithelium of the duodenum, whereas both neutral mucosubstances and sialomucins were demonstrated in the oligomucous cells on 17 day-old fetal rat. 'The brush border contained neutral mucosubstances and sialomucins from 19 day-old fetal rat, and thereafter changed the properties as a mixture of neutral mucosubstances, sialomucins and weak sulfomucins. In the goblet cells, most cells showed a mixture of neutral mucosubstances and strong sulfomucins front 19 day- old fetal rat, but a few cells contained neutral ones only. The amount of neutral and acid mucosubstances increased in the goblet cells of both villi and crypt during the suckling period. However acid mucosubstances increased in the goblet cells of crypt during the weanling period. 'Ihe Brunner's gland contained neutral mucosubstances only from 21 day-old fetal rat, but from the end of suckling period, a few cells located deep gland region contained additional strong sulfomucins.

The hydraulic excavator has been a popular research object for automation because of its multi-workings and economic efficiency. When it works crane tasks, most of disasters happen. The stability of the excavator having crane function has a close relation with excavator's posture, motion and load. In this paper, the stability of tipping-over has been analysed using Zero Moment Point(ZMP),

최창운,이경한,최용,임상무,김상은,이정림,홍성운,김병태 대한핵의학회 1999 핵의학 분자영상 Vol.33 No.3

Purpose: To assess the quantitative accuracy and the clinical utility of 3D volumetric PET imaging with FDG in brain studies, 24 patients with various neurological disorders were studied. Materials and Methods: Each patient was injected with 370 MBq of 2-[18F]fluoro-2-deoxy-D-glucose. After a 30 min uptake period, the patients were imaged for 30 min in 2 dimensional acquisition (2D) and subsequently for 10 min in 3 dimensional acquisition imaging (3D) using a GE AdvanceTM PET system. The scatter corrected 3D (3D SC) and non scatter-corrected 3D images were compared with 2D images by applying ROIs on gray and white matter, lesion and contralateral normal areas. Measured and calculated attenuation correction methods for emission images were compared to get the maximum advantage of high sensitivity of 3D acquisition. Results: When normalized to the contrast of 2D images, the contrasts of gray to white matter were 0.75±0.13 (3D) and 0.95±0.12 (3D SC). The contrasts of normal area to lesion were 0.83±0.05 (3D) 0.96±0.05 (3D SC). Three nuclear medicine physicians judged 3D SC images to be superior to the 2D with regards to resolution and noise. Regional counts of calculated attenuation correction was not significantly different to that of measured attenuation correction. Conclusion: 3D PET images with the scatter correction in FDG brain studies provide quantitatively and qualitatively similar images to 2D and can be utilized in a routine clinical setting to reduce scanning time and patient motion artifacts.

Teratomas are embryonal neoplasms that show characteristics of three germ cell layers(ectoderm, mesoderm, and endoderm). They are distributed in the following regions: sacrococcygeal(57%), gonadal(29%), mediastinal(7%), cervical(3%), retroperitoneal(4%), and intracranial(3%) regions. Non-gonadal treatomas present in infancy whereas gonadal are seen in adolescence. Especially, teratomas that occurred in midline neck of adult are very rare and are confused with thyroglossal duct cysts, cystic hygromas, and thyroid tumors. We report, along with the review of appropriate literature, a case of histopathologically confirmed benign teratoma in the midline neck of a 33 years old woman.

For a preliminary study of a social readjustment rating scale for Korea, 623 individuals over 16-years of age were randomly selected and questioned by a paper and pencil method in Taegu area from May 1980 to August 1980. A scale consisting of 54 items was made ranging from the highest score, death of spouse, to the lowest score, change of residence. Of all the differences between this study and the studies in America, it was notable that, in Korea, higher stress scores were given for child care concerns and problems with in-laws, while a lower score for retirement compared with the studies in America. Female showed higher scores than males and responded particularly sensitively on the problems about marriage. The teenage group and unmarried group noted high stress scores on those problems of sex, study, and peer relationship. Finally the author suggested to do further studies in this field comparing the difference of the Eastern and Western cultural climates.

피조개 발의 조직학적 구조는 hematoxylin-eosin염색 및 Weigert iron hematoxylin염색을, 점액질 성상을 검색하기 위하여 PAS반응, diastase 침지 후 PAS반응, alcian blue pH 2.5염색, alcian blue pH 1.0염색, alcian blue pH 2.5-PAS염색, alcian blue pH 1.0-PAS염색, aldehyde fuchsin pH 1.7-alcian blue pH 2.5염색 및 0.25% toluidine blue염색을 실시하였다. 피조개의 발은 상피, 상피하결합조직 및 근층으로 이루어져 있었으며 상피는 단층섬모원주세포로 되어 있었다. 상피하결합조직 및 근층에 다세포성 점액선인 발선이 발달되어 있었고 도관은 결합조직과 상피세포를 거쳐 개구되어 있었다. 근층은 종주근, 수직근 및 횡근섬유로 구성되어 있었다. 점액질의 조성을 보면 상피세포섬모에는 sialomucin만을, 상피세포는 중성점액질만 함유하고 있었다. 상피세포 및 결합조직내 점액도관에는 산성과 중성점액질의 혼합성인 것과 산성점액질만 함유한 것이 혼재하나 전자가 더 많았다. 산성점액질의 성상으로 보아 대부분이 강 sulfomucin을 가지며 일부는 약 sulfomucin과 sialomucin의 혼합성이었다. 대부분 발선의 점액선포에 대한 점액질 조성은 점액도관과 유사하였으나 일부 상부발선의 점액선포는 중성점액질만을, 하부발선의 점액선포는 sialomucin만을 함유하였다. This study was performed to investigate the histological structure and the histochemical properties of the mucosubstances in the foot of Anadara broughonii. For the histological structure, hematoxylin-eosin and Weigert iron hematoxylin staining were used. The mucosubstances stained with PAS, PAS-diastase, 0.25% toluidine blue, alcian blue pH 2.5, alcian blue pH 1.0, alcian blue pH 2.5-PAS, alcian blue pH 1.0-PAS, aldehyde fuchsin pH 1.7-alcian blue pH 2.5 methods. The foot was composed basically of three layers: epithelium, subepithelial connective tissue and muscular layers. The foot was lined by simple ciliated columnar epithelial cell. Foot glands consisted of multicelluear mucous acini were present in the subepithelial connective tissue and muscular layer. The mucous duct of foot glands was distributed from connective tissue to epithelial cells, and open onto the surface of the foot. The foot muscle traveled in three planes as longitudinal, transverse and vertical muscle fiber. About the properties of mucosubstances on the foot, cilia of epithelial cell contained sialomucin only and epithelial cell neutral mucosubstances only. Most of mucous duct within epithelial cells and connective tissue showed a mixture of acidic and neutral mucosubstances, while a few mucous ducts were contained acidic ones only. Among acidic mucosubstances, notable strong sulfomucin were found in most mucous cell of duct, and a mixture of weak sulfomucin and sialomucin appeared in a few cells. The properties of mucosubstances in the food glands were similiar to those of mucous duct. But a few mucous acini contained neutral mucosubstances and sialomucin only in upper and lower portion of foot gland, respectively.

In this study, torsional and lateral vibrations of a gear box transmission system were analyzed theoretically using some mathematical models and examined to determine the causes of its excessive vibrations. As the results, it was found there exist possibility of resonance between gear mesh frequencies and lateral vibration mode of the transmission shaft during the third shifting mode operation. In order to avoid this resonance, we proposed changing the arrangement of gears on the transmission shaft. The measured vibration levels of the improved gear box were dramatically reduced. These results may be helpful to design a machine tool gear box with low noise and vibration.
