Acrobeads Test를 이용한 정자수정능의 평가

박영수,박남철,Park, Young-Soo,Park, Nam-Cheol 대한생식의학회 1996 Clinical and Experimental Reproductive Medicine Vol.23 No.1

The assessment of acrosomal status is important in evaluating the ability of sperm to fertilize the egg. The acrosomal status of sperm from 47 normal volunteers with proven fertility and 167 subfertile men with not to achieve pregnancy for at least 1 year were evaluated with Acrobeads test(FUSO Pharmaceutical Industries, Ltd, Japan) using immunobeads coated with MH61 monoclonal antibody, which is specific for acrosome-reacted sperm. The mean${\pm}$SD of acrobeads score in 47 volunteer group was $2.8{\pm}0.7$, of which 46(97.9%)cases were ${\geq}$ 2. The mean${\pm}$SD of acrobeads score in 167 subfertile group was $1.7{\pm}0.8$, of which 73(79.3%)cases were ${\leq}$ 1. The aerobe ads score in subfertile group were significantly lower(r=0.294, p<0.05) than those in volunteer group. In subfertile group, acrobeads score were well correlated with the sperm density and motility(r=0.275, r=0.281, p<0.01), but not with semen volume(r=0.16) and serum hormone level(FSH r=0.084, LH r=0.036, testosterone r=0.058, prolactin r=0.006 and estradiol r=0.060)(p>0.05). Of 63 subfertile cases with normozoospermia, 22(34.9%)cases showed 0 or 1 of acrobeads score, which means to accompany with a functional defect in spite of normal morphology. As a results, Acrobeads test is not only a technically simple sensitive procedure with good reproducibility in evaluating the sperm fertilizing capacity but also an useful in the evaluation of effectiveness in the treatment of infertility and the separation of acrosome-reacted sperm in the assisted reproductive technique.

Objectives : This study was designed to find clinical factors that could be differentiated by the lateralization of lesion and also find clinical factors to predict the lateralization of lesion. Methods : The subjects were 65 cooperative inpatients and outpatients with non-traumatic subcortical cerebrovascular disease without neurologic and psychiatric history from January 1995 to September 1995 ; 48 patients in Kyung Hee University, Oriental Medicine Hospital, 35 patients in Anam Hospital, Korea University were examined as subjects, but authors excluded 20 patients whose data were incomplete or who had uncertain lesions on brain CT or MRI. The 65 patients were divided into three groups-group with left hemispheric lesion, group with right hemispheric lesion, group with both hemispheric lesion-according to the finding of brain imaging study. Their cognitive functions were evaluated by the Benton Neuropsychological Assessment(BNA), their subjective neurobehavioral symptoms by Symptom Check List-90-R(SCL-90-R), their objective neurobehavioral symptoms by Neurobehavioral Rating Scale, and their daily living functions by Geriatric Evaluation by Relative's Rating Instrument(GERRl) and Instrumental Activities of Daily Living Scale(IADLs). Results : The results were as follows : 1) The results of cognitive function test indicated that the group with right hemispheric lesion showed low functions in Tactile Form Perception(left), the group with left hemispheric lesion showed low functions in Finger localization(right), the group with right hemispheric lesion showed low functions in Finger Localization(left). 2) Though, there were little significant differences in subjective neurobehavioral symptoms, the group with right hemispheric lesion showed higher scores in all symptoms except hostility. 3) Though, there were little significant differences in objective neurobehavioral symptoms, the group with both hemispheric lesion showed higher scores in cognition, guilty/disinhibition, the group with left hemispheric lesion showed higher scores in lability of mood, the group with right hemispheric lesion showed highest scores in psychotism, neurotism, agitation-hostility and decreased motivation/emotional withdrawal. 4) There were little significant differences among three groups in Daily Living Functions, but the group with right hemispheric lesion showed the lowest functions in Instrumental Activities of Daily Living. 5) As a result of discriminant analysis on each factor's contribution to the prediction of lesion, Finger Localization(left), Phoneme Discrimination and Tactile Form Perception(right) showed that they had the potentiality to predict lesion. Conclusion : The results suggest that there are little significant differences among the groups of three non-traumatic subcortical cerebrovascular disease in cognitive functions, but the group with right hemispheric lesion showed more serious and various changes in subjective and objective neurobehavioral symptoms, and showed low functions in Instrumental Activities of Daily Living. This results suggest the possibility that the decline of the daily living function in the group with right hemispheric lesion were due to various symptoms, not due to cognitive dysfunction. The confirmation of the possibility should be worked out through the follow-up study of some groups containing cortical lesion. Apart from these findings, Finger Localization, Tactile Form Perception(right) and Phoneme Discrimination suggest that they can be used as clinically valuable cognitive parameters that predict the lateralization of lesion in non-traumatic cerebrovascular disease.

박영수,정재용,Park, Young-Soo,Jeong, Jae-Yong 해양환경안전학회 2014 海洋環境安全學會誌 Vol.20 No.5

본 연구에서는 해상교통혼잡도에 영향을 미치는 요소인 선박점용영역크기, 선박의 속력, 항로폭에 대한 민감도 분석을 실시하였으며, 가장 민감한 요소로 선박점용영역을 도출하였다. 선박점용영역에 대해 일본, 덴마크 해협, 중국 상하이항에서의 점용영역에 대한 기존 연구사례를 조사하고, 우리나라 진해만 피항시의 해상교통관측조사를 통한 선박점용영역을 도출하여 비교 분석하였다. 민감도 분석결과, 선박속력 1노트 변화시 10 %, 항로폭 100미터 변화시 18 %, 점용영역 장직경 1L 변화시 34 %~43 %의 영향이 미치는 것으로 분석되었다. 그 결과, 현행 진단제도에서 사용하는 $8L{\times}3.2L$, $6L{\times}1.6L$은 일본의 $3.5L{\times}1.5L$, 중국 상하이항 $5.9L{\times}2.2L$, 덴마크 해협 $4L{\times}5B$ 및 진해만 피항시의 선박점용영역 $3L{\times}2L$과 큰 차이가 있음을 확인하였다. This research concluded that the area is most sensitively affected by the maritime traffic congestion rather than other factors including the ship's speed and fairway width. We performed a literature review for the area used in Japan, Denmark, and Shanghai ports, and analyzed by comparing with the area in Jinhae, Korea through the observation survey of marine traffic. The result of sensitivity analysis concluded that the congestion is affected by amount of 10% by changing 1 knot of the ship's speed, 18% of 100m of the fairway width, and 34%~43% of 1L of ship's length. By applying the result into the current audit system using $8L{\times}3.2L$, $6L{\times}1.6L$, we found that there is big difference with $3.5L{\times}1.5L$ in Japan, $5.9L{\times}2.2L$ in Shanghai, $4L{\times}5B$ in Denmark, and $3L{\times}2L$ in Jinhae, Korea. For this reason, further studies should be carried out in near future to the area mostly affected by congestion.

박영수,Park, Young Soo 한국디지털정책학회 2014 디지털융복합연구 Vol.12 No.12

본 논문에서는 HTML5에서 Quadratic & Cubic B$\acute{e}$zier 곡선을 이용하여 2D 이미지를 3D 입체 이미지로 변환하는 방법을 제안한다. 3D 입체 이미지 변환은 원본 이미지에서 RGB색상 값을 분리 추출하여 좌안과 우안을 위한 2개의 이미지로 필터링한다. 사용자는 Quadratic B$\acute{e}$zier 곡선과 Cubic B$\acute{e}$zier곡선을 이용한 제어 점을 통해 이미지의 깊이 값을 설정하게 된다. 이 제어 점을 기반으로 2D 이미지의 깊이 값을 계산하여 3D이미지에 반영하게 된다. 이 모든 과정은 HTML5를 사용한 웹 환경에서 구현하였으며, 사용자들은 매우 쉽고 편리하게 자신들이 원하는 3D 이미지를 만들 수 있게 하였다. In this paper, we propose a method to convert 2D image to 3D anaglyph using quadratic & cubic B$\acute{e}$zier Curves in HTML5. In order to convert 2D image to 3D anaglyph image, we filter the original image to extract the RGB color values and create two images for the left and right eyes. Users are to set up the depth values of the image through the control point using the quadratic and cubic B$\acute{e}$zier curves. We have processed the depth values of 2D image based on this control point to create the 3D image conversion reflecting the value of the control point which the users select. All of this work has been designed and implemented in Web environment in HTML5. So we have made it for anyone who wants to create their 3D images and it is very easy and convenient to use.
