The aim of this study make it clear the trait of physical strength according to Physique index and help the Physical fitness leaders to raise the function of exercise and provide them with study programs by stage in the sport learning. For this study 620 students (male & female students in 5 and 6 class of elementary school) were selected. The result of study show outstanding physical trait in body weight ratio and chest girth ratio. The results are the following. (1) The physical characteristics of the investigated children, around 5 class or 6 class, show that female children's growth is faster than male's. (2) The trait of Physical Fitness shows it is superior in male's group and as grow older, but the group of 5 class is more superior than the group of 6 class, in male's and female's pull-ups. (3) The correlation between physique index shows the highest correlation(P< .01) in body weight and girth of chest, next is height and sitting height, height and girth of chest, followed by girth of chest and sitting height. (4) The correlation between 100m sprint and physical fitness shows high positive interrelation(P< .01) in 600m distance run, but negative interrelation(P< .01) in standing broad jump, pull-ups, sit-ups and ball throwing. (5) The correlation between standing broad jump and physical fitness shows positive interrelation(P< .01) in sit-ups, pull-ups and ball throwing, but negative interrelation(P< .01) in 100m sprint and 600m distance run. (6) The correlation between pull-ups and physical fitness shows positive interrelation(P< .01) in sit-ups, standing broad jump and ball throwing, but negative interrelation(P< .01) in100m sprint and 600m distance run.

The ultrastructures of the glandular hairs in leaf of Thymus quinquecostatus were investigated using transmission electron microscope. The glandular hair was consisted of three cell layers ; an epidermal cell layer, a stalk cell with single-celled intermediate layer and a discoid secretory layer with thickened cuticle. The glandular hair possessed an enlarged secretory cavity covered with a thick cuticle and subjacent cell wall, formed from the secretory cell which were subtended by a stalk cell supported by an epidermal cell. The secretory vesicles, originated from Golgi complex, appeared as membrane bounded vesicles and secreted to the outer wall surface. Subcuticular cavity was developed between the subcuticular layer and the secretory cell wall, and it formed above the secretory cell upon separation of cuticle-wall. The presence of well developed rER, mitochondria, Golgi complex, plastids, and membrane-bounded vesicles fused with plasmalemma in the secreting cells indicates that the granulocrine mechanism of secretion is occurring in T. quinquecostatus.

Finite failure NHPP software reliability models presented in the literature exhibit eitherconstant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. Inthis paper, proposes the Gompertz distribution reliability model, which made out efficiencyapplication for software reliability. Algorithm to estimate the parameters used to maximumlikelihood estimator and bisection method, model selection based on mean square error(MSE) and coefficient of determination(R²), for the sake of efficient model, was employed. Analysis of failure using real data set for the sake of proposing fixed shape parameter of theGompertz distribution was employed. This analysis of failure data compared with theGompertz distribution model of shape parameter. In order to insurance for the reliability ofdata, Laplace trend test was employed. In this study, the proposed Gompertz model is more efficient in terms of reliability in thisarea. Thus, Gompertz model can also be used as an alternative model. From this paper,software developers have to consider the growth model by prior knowledge of the softwareto identify failure modes which can was helped

신현철,장희선 한국융합보안학회 2002 융합보안 논문지 Vol.2 No.2

멀티미디어 인터넷 망에서 호 라우팅은 번호나 이름을 라우팅 주소로 번역하며 라우팅 주소는 연결 설정을 위해 사용된다. 트래픽 엔지니어링 기능은 트래픽 관리(Traffic Management), 용량 관리(Capacity Management), 그리고 네트워크 계획(Network Planning) 등을 포함한다. 본 논문에서는 트래픽 엔지니어링의 기능 중 트래픽 관리 기능에서 호 라우팅(Call Routing)과 연결/베어러-패스라우팅을 위한 기본 기능을 제시한다. We use the call routing to interpret the number or name for routing address in multimedia internet. The routing address is used for connection setup. The traffic engineering consists of traffic management, capacity management and network planning. In this paper, in the traffic management function, the basic functions for call routing and connection/bearer-path routing will be presented.

Objective : Somatosensory evoked potentials(SSEPs) have been used widely both experimentally and clinically to monitor the function of central nervous system and peripheral nervous system. Studies of SSEPs have reported the various recording techniques and patterns of SSEP. The previous SSEP studies used scalp recording electrodes, showed mean vector potentials which included relatively constant brainstem potentials(far-field potentials) and unstable thalamocortical pathway potentials(near-field potentials). Even in invasive SSEP recording methods, thalamocortical potentials were variable according to the kinds, depths, and distance of two electrodes. So they were regarded improper method for monitoring of upper level of brainstem. The present study was conducted to investigate the characteristics of somatosensory evoked field potentials(SSEFPs) of the cerebral cortex that evoked by hindlimb stimulation using ball electrode and the pathways of SSEFP by recording the potentials simultaneously in the cortex, VPL nucleus of thalamus, and nucleus gracilis. Methods : In the first experiment, a specially designed recording electrode was inserted into the cerebral cortex perpendicular to the cortical surface in order to recording the constant cortical field potentials and SSEFPs mapped from different areas of somatosensory cortex were analyzed. In the second experiment, SSEPs were recorded in the ipsilateral nucleus gracilis, the contralateral ventroposterolateral thalamic nucleus(VPL), and the cerebral cortex along the conduction pathway of somatosensory information. Results : In the first experiment, we could constantly obtain the SSEFPs in cerebral cortex following the transcutaneous electrical stimulation of the hind limb, and it revealed that the first large positive and following negative waves were largest at the 2mm posterior and 2mm lateral to the bregma in the contralateral somatosensory cortex. The second experiment showed that the SSEPs were conducted by way of posterior column somatosensory pathway and thalamocortical pathway and that specific patterns of the SSEPs were recorded from the nucleus gracilis, VPL, and cerebral cortex. Conclusion : The specially designed recording electrode was found to be very useful in recording the localized SSEFPs and the transcutaneous electrical stimulation using ball electrode was effective in evoking SSEPs. The characteristic shapes, latencies, and conduction velocities of each potentials are expected to be used the fundamental data for the future study of brain functions, including the hydrocephalus model, middle cerebral artery ischemia model, and so forth.
