음식에는 한 나라의 역사와 문화가 고스란히 담겨 있다고 한다. 특히 오랫동안 우리의 삶과 함께 해온 발효식품에는 우리 조상들의 깊은 지혜와 더불어 그 시대의 문화뿐만 아니라 과학 또한 숨겨져 있다고 해도 과언이 아니다. 어떻게 생각하면 현대의 과학과는 맞지 않는 비과학적일 수 있다는 생각이 들지만 전통음식이란 지금까지의 수많은 시간동안 체계적이고 영양면에서도 과학적인 조리법에 의해 이어져 내려온 훌륭한 식품이라 불리는 데 있어 전혀 손색이 없다고 할 수 있다.

박영수,위인희,조우석,김진호,황광택,Park, Young-Soo,Wui, In-Hee,Cho, Woo-Seok,Kim, Jin-Ho,Hwang, Kwang-Taek 한국결정성장학회 2012 한국결정성장학회지 Vol.22 No.6

알루미늄 에칭 폐액으로부터 boehmite(AlOOH) 분말을 합성하였다. 폐액에서 침전되어 있는 결정상은 gibbsite ($Al(OH)_3$)였으며, 산을 이용하여 pH를 조절한 결과 pH가 7~8 영역에서 boehmite 결정상이 얻어졌다. 침전 분말에 남아 있는 Na 이온을 제거하고자 세척공정을 진행하여 boehmite 분말을 얻었다. 합성한 분말의 평균입경은 약 40 nm이었다. 또한 열처리 온도가 증가함에 따라 boehmite는 ${\gamma}-Al_2O_3$와 ${\delta}-Al_2O_3$, ${\Theta}-Al_2O_3$를 거쳐 ${\alpha}-Al_2O_3$ 결정상으로 상전이가 일어났다. Boehmite (AlOOH) powder was synthesized using waste aluminium etching solution. In waste solution, precipitated phase was gibbsite ($Al(OH)_3$), and boehmite (AlOOH) phase was obtained at pH of 7 and 8 controlled by addition of acid. Boehmite powder was obtained by washing process to remove the Na ion in precipitated solution. Mean particle size of obtained powder was 40 nm. Boehmite phase transformed to ${\alpha}-Al_2O_3$ phase via ${\gamma}-Al_2O_3$, ${\delta}-Al_2O_3$, and ${\Theta}-Al_2O_3$.

박영수,박인학,Park, Y.S.,Park, I.H. 한국전자통신연구원 1998 전자통신동향분석 Vol.13 No.1

전역 클럭을 사용하는 동기 회로 설계 기술은 설계의 단순화 및 자동화가 용이하기 때문에 현재 많이 사용하는 설계 기술이다. 그러나 다양한 기능과 고성능을 필요로 하는 대규모 시스템이나 회로 설계에서는 전역 클럭 사용으로 인한 신호 지연, 전력 소모 등이 문제로 부각되면서 비동기 회로 설계 기술이 각광을 받고 있다. 비동기 회로 설계 기술은 1940년대에 개발된 기술이지만 설계 자체가 어렵고 면적 증가 등의 단점으로 제한된 분야에서 이용되었다. 현재 이러한 단점을 극복하기 위한 연구가 회로 설계, 검증, 동기/비동기 인터페이스, 그리고 저전력 회로 등의 분야에서 많이 진행되고 있다.

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.

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.
