넙치(Paralichthys olivaceus)에서 호르몬 처리에 의한 효과적인 인공산란 연구의 일환으로 human chorionic gonadotropin(HCG)에 의한 성숙 넙치에서의 spermatocrit법에 의한 배정(spermiation)효과를 연구하였다. 안정된 spermatocrit치를 위한 정액의 분획조건은 12,000rpm, 30분간의 원심분리가 적절하였으며 spermatocrit(Y)는 정자밀도(X)와는 Y=1.14X-10.04(r=0.91, P<0.0001, n=50)의 관계식을 나타내었다. 정자밀도는 21.5∼98.4×10??정자/㎕정액으로 12∼95%의 spermatocrit치에 해당하였다. 성숙넙치의 정액생산은 1,000IUHCG/㎏BW의 주사시 24시간후에 가장 높았고(7.46㎖/㎏BW), 낮은spermatocrit치(63%)와 낮은 정자밀도(67.4×10??정자/㎕정액)수준과 일치하여 정액점도는 매우 낮게 나타났다. 이와같은 낮은 정액점도는 HEG처리에 의한 정소의 수화(hydration)에 기인된 것으로 여타 lobular형 정소에서의 호르몬 처리시 결과와 일치하였다. 48시간후의 HCG처리군과 대조군간의 정액생산, spermatocrit치 및 정자밀도에서는 유의한 차이를 보이지 않았다. 본 연구결과 성숙넙치의 배정은 spermatocrit법에 의해 명확히 판별될 수 있으며 HCG는 본 종에서 배정을 효과적으로 촉진시킬 수 있음이 나타났다. For the evaluation of hormonal control of sperm in cultured fish a method to quantify the spermiation response of mature flatfish to hormonal therapy is described. Spermatocrit was determined after 30 min. in centrifuge condition of 12,000rpm. Sperm density was estimated by a standard hemacytometer method. However, sperm density can be predicted from spermatocrit since their relationship is linear as described by the regression equation, Y=1.14X-0.04(r=0.91, P<0.0001, n=50), where Y is spermatocrit and X is sperm density. Sperm density levels ranged from 21.5 to 98.4×10?? spermatozoa per ㎕ milt corresponding to spermatocrit values of 12 to 95%. Milt production by mature flatfish was highest(7.4ml per ㎏ body weight) at 24h after injection of 1,000IU of human chorionic gonadotropin(HCG) per ㎏ body weight and coincided with low spermatocrit(63%) and sperm density(67.4×10?? spermatozoa per ㎕ milt) levels. No significant differences was appeared in milt production, spermatocrit and sperm density between control and HCG-treated fish at 48h after HCG injection. These results demonstrate that spermiation in mature flatfish can be reliably evaluated by a spermatocrit method and that HCG is effctive in stimulating of spermiation in this species.

In the past time, the protection relay did only a protection function. Currently, its upgraded device i.e. IED (Intelligent Electric Device) has been designed to protect, control, and monitor the whole power system automatically. Also the device is desired to successfully measure important elements of the power system. This paper considers design method of a digital protection IED with a function of measuring various elements and a communication function. The protection IED is composed of the specific function modules that are signal process module, communication module, input/output module and main control module. A signal process module use a DSP processor for analysis of input signal. Main control module use a embedded processor, Xscale, that has an ARM Core. The communication protocol uses IEC61850 protocol that becomes standard in the future. The protection IED is able to process mass information with high-performance processor. As each function module is designed individually, the reliability of the device can be enhanced.

This is a case report of difficult eruption of succeeding permanent tooth by periapical inflammation of primary tooth. 12-year-8-month-old girl who had been treated by pulpotomy of lower right second primary molar about 4 years ago was recalled for prolonged retention of it. Radiographs showed periapical inflammation of lower right second primary molar and horizontal buccal impaction of succeeding permanent tooth. Right second premolar seemed impossible to erupt so surgical extraction of it was done with removal of lower right second primary molar and resin space maintainer was manipulated for prevention of space closure and elongation of opposing tooth.

본 연구는 한국인의 삶의 질 향상을 위한 국민 생활체육 진흥정책 수립에 필요한 기초자료를 제공하기 위하여, 건강한 30-60대 서울시민(313명)의 체격과 근력, 전신지구력 등의 체력을 측정하여 문화, 경제생활수준이 서로 빠른 동경시민(509명) 및 북경시민(160명)과 비교 검토하는 것을 목적으로 하였다. 각국의 연구대상에 대한 측정은 사전에 협의한 동일한 방법(동경대학 체육과학실법)과 기기를 이용하였다. 체격요인으로는 신장과 체중을, 체력요인으로는 트레드밀 보행시 (90m/분)의 심박수와 보폭 그리고 자전거 에르고미터 운동시의 PWC75%HRmax와 脚筋伸展파워를 측정하였다. 신장 및 체중, 신체질량지수는 남녀 모두 북경, 서울, 동경시민순으로 높게 나타났다. 트레이드밀 보행시의 심박수는 남녀 모두 북경, 동경, 서울시민 순으로 낮은 값을 보였으며, 신장에 대한 보폭비율은 남자의 경우에는 북경, 서울, 동경의 순으로, 여자는 북경, 동경, 서울의 순으로 높았다. 脚筋伸展파워는 60대 여자를 제외한 남녀 모두 북경, 서울, 동경시민의 순으로 높았으며, PWC75%Hrmax는 남자 40대 와 여자 30대를 제외한 모든 연령 대에서 서울시민이 동경시민 보다 높은 경향을 나타냈다. 한편 모든 피검자를 대상으로 연령과 脚筋伸展파워와의 회귀식은 남녀 각각 Y=-0.30X+28.88(n=230, r=0.61, p<.001), Y=-0.l0X +12.49(n=611, r=0.32, p<.001), PWC75%HRmax와의 회귀식은 남녀 각각 Y=-0.01+ 2.50(n=116, r=0.29, p<.01), Y=-0.l0X+1.89(n=461, r=0.20, p<.001)이였다. 따라서 30~60대 서울시민의 체격 및 脚筋伸展파워는 북경시민 보다 낮게 나타나 삶의 질 향상을 위해 보다 적극적인 사회체육 활성화 방안 마련이 요망된다. The purpose of this study was to serve as a basis for making a health promotion policy for better quality of Korean life, by examining 313 citizens of Seoul's physical and leg extension power, physical working capacity who were in their thirties to sixties, enjoying good health, and by making a comparison of tile result with that of 509 citizens of Tokyo and 160 citizens of Peking who lived in different culture and living environment. The findings of this study were as below: First, the male citizens of Peking, who were in their forties to sixties, and the female citizens of the same city, who were in their fifties to sixties, were significantly higher in height, body weight and body mass index. Second, the male citizens of Peking, who were in their thirties and sixties, and the female citizens of the same city, who were in their thirties to forties, were significantly lower in heart rate in walking in the treadmill(90n/min). And there was a tendency that the citizens of Peking showed a higher ratio of stride to height. Third, the male citizens of Peking, who were in their fifties, and the female citizens of the same city, who were in their thirties to forties, had a significantly better leg extension power. As a result of examining all the subjects, there was a negative correlation between leg extension power and age. Fourth, all age groups of Seoul citizens, except males in their forties and females in their thirties, fended to be better in PWC75%HRmax than the citizens of Tokyo. When all the subjects were examined, there was a negative correlation between PWC75%HRmax and age. Consequently, there was a need to prepare more active plan to step up sports fur all successfully in order to improve the quality of life, as the citizens of Seoul who were their thirties to sixties appeared to be inferior in physical physique and leg extension power to the citizens of Peking.

Spermatocrit was determined after 30 min. in centrifuge condition of 12,000rpm. Sperm density was estimated by a standard hemacytometer method. However, sperm density can be predicted from spermatocrit since their relationship is linear as described by the re-gression equation. Y=1.14X-0.04 (r=0.91. P<0.0001. n=50), where Y is spermatocrit and X is sperm density. Sperm density levels ranged from 21.5 to 98.4×10^(4) spermatozoa per ㎕ milt corresponding to spermatocrit values of 12 to 95%. Milt production by mature flatfish was highest (7.4ml per kg body weight) at 24h after injection of 1,000IU of human chorionic gonadotropin(HCG) per kg body weight and coincided with low spermatocrit (63%) and sperm density (67.4×10^(4) spermatozoa per ㎕ milt) levels.

<P>A 16-year-old, castrated, male English cocker spaniel dog was presented due to generalized alopecia. Routine clinical pathology, endocrine and abdominal ultrasonography results were consistent with a diagnosis of pituitary-dependent hyperadrenocorticism. The adenohypophyseal lesion was clearly visualized on both 3 T and 7 T magnetic resonance imaging (MRI) of the pituitary gland. Although biochemical and MRI findings were consistent with a functional pituitary microtumor, a pituitary lesion was not detected using <SUP>18</SUP>F-fluorodeoxyglucose positron emission tomography (FDG-PET). This report firstly describes the application of high-resolution FDG-PET to a spontaneous pituitary microtumor in a dog.</P>

레이저 직접금속성형기술을 이용한 금형재 표면보수 특성 연구

Direct laser metal forming technology was applied to restore the damaged mold surface. In order to estimate melting characteristics of the 20 ㎛ Fe-Cr-Ni powder, single layer experiments were performed at various levels of heat input. The process window of the 20 ㎛ Fe-Cr-Ni powder provided feasible process parameters for the smooth regular surface. The cross hatching scanning strategy on the multiple layer experiment was performed to reduce the thickness non-uniformity of edge portions compared with the one direction scanning. To estimate the coherence between the melted powder and the basematal, the tendency of hardness distribution has been observed. The hardness of the melted and the remelted zone was distributed from 400HV to 600HV. It is over 2 times compared of the hardness of the basemetal. Experimental results show that the mold restoring process using direct laser metal forming can be successfully applied in the mold repair industry.
