이원용(Won Yong Lee),이진(Jin Lee),문은이(Eun Yi Moon),남순철(Soon Chul Nam),이덕근(Dug Keun Lee),윤성준(Sung June Yoon) 한국응용약물학회 1997 Biomolecules & Therapeutics(구 응용약물학회지) Vol.5 No.1

DW-166HC (^(166)Holmium-chitosan) is a complex of ^(166)Ho, (β- and γ- ray emitter, and chitosan, a polymer of glucosamine, with radiotherapeutic potential. The current study was performed to determine the acute toxicities of ^(165)Ho-chitosan in mice by two different routes of administration. The both sex mice were given a single intravenous bolus injection of ^(165)Ho-chitosan complex at doses of 12, 10, 6, 5 and 4 mg/kg or subcutaneous administration at doses of 600, 500, 400 and 300 mg/kg. Chitosan was dosed to control animals as 16 and 800 mg/kg, intravenously and subcutaneously, respectively. The doses of ^(165)Ho-chitosan complex were expressed as ^(165)holmium nitrate pentahydrate and the ratio of ^(165)Ho(NO₃)₃, ·5H₂0 to chitosan was 3/4. Severe convulsion and respiratory failure were followed by death within 10 min after intravenous dosing. Transient unilateral hindlimb hypokinesias were found in two mice of 5 mg/kg dosing group during the study period. No abnormalities were observed during the necropsy of survived animals in intravenous dosing group. Only one male animal was found dead in 500 mg/kg subcutaneously dosed group. Alopecia with or without cutaneous ulcer were found in most mice including control animals. During necropsy, omental adhesion was observed in all dose ranges and enlarged spleen was found in several animals including control group. It is suggested that the acute intravenous LD_(50)s for male and female mice were 4.90 and 6.03 mg/kg, respectively. The lowest lethal dose in male was 500 mg/kg by subcutaneous administration.

어트랙터 해석을 이용한 레일 용접부의 결함 평가

이원,윤인식,권성태,Yi, Won,Yun, In-Sik,Kwon, Sung-Tae 한국철도학회 1999 한국철도학회논문집 Vol.2 No.1

This study proposes the analysis and evaluation method of time series ultrasonic signal using the attractor analysis. Features extracted from time series signal analyze quantitatively characteristics of weld defects. For this purpose, analysis objective in this study is fractal dimension and attractor quadrant feature. Trajectory changes in the attractor indicated a substantial difference in fractal characteristics resulting from distance shifts such as parts of head and flange even though the types of defects are identified. These differences in characteristics of weld defects enables the evaluation of unique characteristics of defects in the weld zone. In quantitative fractal feature extraction, feature values of 3.848 in the case of part of head(crack) and 4.102 in the case of part of web(side hole) and 3.711 in the case of part of flange(crack) were proposed on the basis of fractal dimensions. Proposed attractor feature extraction in this study can enhance the precision rate of ultrasonic evaluation for defect signals of rail weld zone such as side hole and crack.

이원,윤인식,Yi, Won,Yun, In-Sik 대한기계학회 1999 大韓機械學會論文集A Vol.23 No.7

This study proposes the analysis and evaluation method of time series ultrasonic signal using the chaotic feature extraction for ultrasonic pattern recognition. Features extracted from time series data using the chaotic time series signal analysis quantitatively welding defects. For this purpose analysis objective in this study is fractal dimension and Lyapunov exponent. Trajectory changes in the strange attractor indicated that even same type of defects carried substantial difference in chaoticity resulting from distance shills such as 0.5 and 1.0 skip distance. Such differences in chaoticity enables the evaluation of unique features of defects in the weld zone. In experiment fractal(correlation) dimension and Lyapunov exponent extracted from 6dB ultrasonic defect signals of weld zone showed chaoticity. In quantitative chaotic feature extraction, feature values(mean values) of 4.2690 and 0.0907 in the case of porosity and 4.2432 and 0.0888 in the case of incomplete penetration were proposed on the basis of fractal dimension and Lyapunov exponent. Proposed chaotic feature extraction in this study enhances ultrasonic pattern recognition results from defect signals of weld zone such as vertical hole.

시기별 해충의 발생량을 파악하는 것은 유연한 방제 계획 수립을 가능케 한다. 기존에는 해충의 발생량을 파악하기 위해 사람이 페로몬 트랩에 잡힌 해충의 마릿수를 직접세는 방식으로 수행되어왔다. 따라서 주광성 기반의 디지털 트랩에서 촬영된 해충 영상을 기반으로 해충의 마릿수를 자동으로 파악하는 해충 카운팅 딥러닝 모델을 소개하고자 한다. 디지털 트랩 안의 해충의 마릿수가 많아질수록 폐색 문제가 발생한다. 이러한 문제를 해결하기 위해 이전 연구에서 멀티스케일 CenterNet을 제안하였다. 하지만 여전히 해충 카운팅 성능 개선에 대한 문제가 남아있다. 따라서 본 연구에서는 해충 카운팅 성능 개선을 위한 멀티스케일 어텐션 CenterNet을 제안하고자 한다. 연구 결과를 통해 해충 카운팅의 성능을 개선할 수 있음을 보이고자 한다. Identifying the amount of occurrence of pests by season makes it possible to establish a flexible control plan. Conventionally, in order to determine the amount of pests generated, a person has been performing a method of directly counting the number of pests caught in a pheromone trap. Therefore, we would like to introduce a deep learning model for counting pests that automatically counts the number of pests based on images of pests taken from phototight-based digital traps. The blockage problem occurs as the number of pests in the digital trap increases. To solve this problem, a multiscale CenterNet was proposed in previous studies. However, there is still a problem to improve pest counting performance. Therefore, in this study, we propose a multiscale attention CenterNet to improve pest counting performance. The results of this study are intended to show that the performance of pest counting can be improved.

This paper is concerned with defects detection and evaluation of heat affected zone (HAZ) in austenitic stainless steel type 304 by ultrasonic wave and neural network. In experiment, the reflected ultrasonic defect signals from artificial defects (side hole, vertical hole, notch) of HAZ appears as beam distance of prove-defect, distance of probe-surface, depth of defect-surface on CRT. For defect classification simulation, neural network system was organized using total results of ultrasonic experiment. The organized neural network system was learned with the accuracy of 99%. Also it could be classified with the accuracy of 80% in side hole, and 100% in vertical hole, 90% in notch about ultrasonic pattern recognition. Simulation results of neural network agree fairly well with results of ultrasonic experiment. Thus were think that the constructed system (ultrasonic wave - neural network) in this work is useful for defects dection and classification such as holes and notches in HAZ of austenitic stainless steel 304.

This study proposes th analysis and evaluation method of time series ultrasonic signal using the chaos feature extraction for ultrasonic pattern recognition. Features extracted from time series data using the chaos time series signal analyze quantitatively weld defects. For this purpose, analysis objective in this study is fractal dimension and Lyapunov exponent. Trajectory changes in the strange attractor indicated that even same type of defects carried substantial difference in chaosity resulting from distance shifts such as 0.5 and 1.0 skip distance. Such differences in chaosity enables the evaluation of unique features of defects in the weld zone. In quantitative chaos feature extraction, feature values of 4.511 and 0.091 in the case of side hole and 4.539 and 0.115 in the case of vertical hole were proposed on the basis of fractal dimension and Lyapunov exponent. Proposed chaos feature extraction in this study can enhances ultrasonic pattern recognition results from defect signals of weld zone such as side hole and vertical hole.
