Digital high resolution cameras are widely available. and are increasingly use in digital close-range photogrammetry. And photogrammetry instruments are developing rapidly and the precision is improving continuously. The building of 3D terrains of high precision are possible and the calculation of the areas or the earthwork volumes have high precision due to the development of the technique of the spatial information system using computer. Using the digital camera which has capacity of keeping numerical value by itself and easy carrying. we analyze the positioning error according to various change of photographing condition. Also we try to find a effective method of acquiring basis data for 3D monitoring of high-accuracy in pixel degree through digital close-range photogrammetry with bundle adjustment for local terrain model generation and 3D embodiment of tumulus. In the study is about to efficient analysis of digital information data for conservation of cultural properties.

The purpose of this study was to investigate the mean cranial bone thickness at various points of the bone and to serve as a clinical guide for choosing a bone graft. Twelve bones were obtained from 6 Korean adult skulls for this study. The mean bone thickness at each point of the 17 points of the bone and at the corresponding points of the opposite bone was obtained in all skulls studied. The thinnest part of the parietal bone was 5.92mm. The thickest part of the parietal bone was 7.58mm. The mean bone thickness at each point of measurements on two opposite bones was compared using the paired Student's t-test. The mean thickness did not differ significantly. The thickness in the same bone varied widely depending on the points of measurement.

Background: Propofol is a good induction agent. but it has a disadvantage of pain on intravenous injection. Pretreatment of metoclopramide or lidocaine have been reported to reduce pain on injection. thus, we have evaluated the quantity and quality of anagesic effect of metoclopramide and lidocaine. We observed differences in quality of pain according to venous cannula sizes and intravenous injection sites as well as nausea and vomiting in the postoperative state. Methods: Eighty patients scheduled for an elective operation by general anesthesia were chosen according to ASA (Ⅰ or Ⅱ) and divided into four groups randomly. Each group was injected through venous cannulas with normal saline (control group), metoclopramide 5 mg (group 1), netoclopramide 10 mg (group 2), or 2% lidocaine 40 mg (group 3) respectively. Then, propofol was injected of a 2 mg/kg dose with 0.5 ml/sex to all groups and we asked questions about injection pain after 10 seconds. Results: Pain relief was shown in all groups compared with the control. but metoclopramide 10 mg and lidocaine 40 mg pretreatment groups showed significant pain reief. Pain was relieved significantly when the drug was injected in the antecubital area. Postoperative nausea and vomiting were not observed. Conclusions: Metoclopramide 10 mg or lidocaine 40 mg pretreatment to induction by propofol revealed a good analgesic effect for propofol injection pain. (Korean J Anesthesiol 2002; 43: 558~565)

근거리 수치사진측량의 정확도 향상에 관한 연구

박운용,김진수,정공운 동아대학교 건설기술연구소 2003 硏究報告 Vol.27 No.1

As state-of-the-art usually high-quality digital cameras are used for photogrammetric industrial metrology. Digital high-resolution consumer cameras are widely available. and are increasingly used in close-range photogrammetry. The mechanical construction of the cameras often do not meet photogrammetric requirements, thus they have to be modelled sufficiently. The close-range photogrammetry is a surveying technique the acquiring the 3D object from 2D geometric appearance shown in the image. Camera treatment is relatively so simple. Camera position refer to the object can be freely adjusted by locating the exposure station at any site. So it is used effectively a small area or object for survey. In this study, suing the digital camera which has capacity of keeping numerical value by itself and easy carrying, we analyze the positioning error according to various change of photographing condition. Also we try to find effective method of acquiring basis data for 3D monitoring of high-accuracy in sub-pixel degree through digital close-range photogrammetry with bundle adjustment for local terrain model generation.

Odontogenic fibromyxomas are extremely rare benign odontogenic tumors that probably arise from interstitial portion of jaw bone. The plain X-ray showed osteolytic destructive lesions in the molar root area. CT scans demonstrated osteolytic expansile lesions with mild enhancement of the solid portion of the mass. Histologically, the tumor is composed of fibrous tissue and myxoid tissues. In this paper a case of odontogenic fibromyxoma of the maxilla and a review of the literature is presented.

We report a case in which a right mandibular incisor was impacted beneath an odontoma in the anterior mandible. An odontoma at the symphyseal region was removed under general anesthesia, and bone was grafted. Tooth #41, which was beneath the lesion, was extracted and transplanted to its original site. It was splinted with resin for 2 weeks and was checked at intervals during that time. After 4 months, it was filled endodontically with calcium hydroxide.

GPS/GLONASS 결합에 의한 차량의 동적상대측위 정확도 비교

박운용,이재원,이인수 동아대학교 2001 大學院論文集 Vol.26 No.-

Nowadays stand-alone GPS sarellite navigation system determines the kinematic positions of vehicle. but in the bad environment such as urban canyon, only stand-alone GPS can't afford to determine the vehicle's positions accurately, so until now the with complementary methods like Dead Reckoning, etc. have been used. Therefore, on this study, combining the GPS and GLONASS, operated by the former Soviet Union(SU), combined the author acquired the data of vehicle's positions even in the worse environments where only stand-alone GPS can't receive the data. And also results in good values in the post-processed methods such as DGPS or OTF. But it is impossible in the worst environments so far, so it is expected to study about it more.

Pilomatricoma or calcifying epithelialioma of Malherbe is an uncommon, benign growth with origination from the epithelial hair matrix or a skin appendage manifestating as a firm, solitary or multiple lesion of face and upper extremity. It generally measures several mm to cm in diameter and typically found in young people. We report a 14-year-old male who developed solitary mass on the left buccal cheek. The size of tumor was 4.5 by 3.5cm. Microscopically, the histologic appearance showed demarcated tumor lobules with thin fibrous capsule composed of eosinophilic shadow cells, basaloid cells and partial calcified area. We described unusual case of giant pilomatricoma and the typical features, variants, histopathogenesis, differential diagnosis, and therapy are reivewed

The purpose of this study was to investigate the eating behaviors and food preferences of university students. The survey was carried out through questionnaire and the subjects were 250 students in Chungbuk National University. Results showed that eating behaviors and food preferences of university students were concerned with general status. And most of the lodgers and the cooking food for themselves showed that their eating behaviors were irregular. As the result, It is necessary that university students were taught eating behaviors and food preferences right.

우리나라와 같이 B형 간염 바이러스의 유병율이 높은 지역에서는 B형 간염 바이러스 뿐만 아니라 HCV에 대한 항 바이러스 효과도 동시에 시행함이 유용할 것으로 사료되었다. 본 연구에서는 茵蔯淸肝湯을 이용하여 B형 간염 바이러스에 대한 抗 바이러스 효과를 PCR을 이용하여 HBV의 DNA를 검색하였다. 茵蔯淸肝湯이 처리된 처리군의 경우 대조군에 비하여 농도 의존적으로 B형 간염 바이러스의 표면항원 생산을 억제하였고, PCR을 이용하여 증폭한 경우에도 증폭된 DNA의 양은 감소하였다. 또한 C형 간염 바이러스에 대한 抗 바이러스효과를 검색하기 위하여 복제에 필수적인 단백질인 HCV helicase의 ATPase에 대한 활성 억제 효과를 조사하였다. 茵蔯淸肝湯이 HCV helicase의 ATPase 활성을 억제하는 효과가 있음을 확인한 후 dose-respond에 따른 실험을 수행하여 HCV helicase의 ATPase 활성을 억제함으로써 탈인산화 되지 않은 ATP의 양을 이용하여 PSL로 분석한 결과 茵蔯淸肝湯이 HCV helicase의 ATPase 기능에 대한 억제효과가 우수함이 확인되었다. 이상의 결과로 보아 茵蔯淸肝湯이 B형 및 C형 간염 치료에 동시에 응용될 수 있을것으로 사료된다. For the purpose of investigate the inhibition effects of Injinchunggantang on Hepatitis and C Virus. The inhibition experiments were as follows : 1. The inhibition effects of Hepatitis B surface antigen production was remarkably increased in the pretreated group of Injinchunggantang compared with control group. 2. Amplified PCR products of HBV-DNA in culture media was considerably decreased in the pretreated group of Injinchunggantang compared with control group. 3. Results of ATP quantitation and ATPase inhibition percent was increased pretreated group of Injinchunggantang. Also ATPase activity of HCV helicase inhibition assay was increased with a dose dependent manner. These results may suggest that Injinchunggantang will have the inhibition effects of Hepatitis B and C Virus.
