  • This experimental studies was to investigate location of labeled neurons in CNS following injection of pseudorabies virus(PRV), Bartha strain, into the uterus and Sanyinjiao(Sp6) of rats. After survival times of 4-5 days following the injection of PRV, the rats were perfused, and their brain and spinal cord were frozen sectioned($30\mu\textrm{m}$). These sections were stained by PRV immunohistochemical staining methods, and observed with light microscope. The results were as follows: 1. In the spinal cord, overlap areas of PRV labeled neurons projecting to uterus and Sp6 were observed in lamina VII, IX and X areas of cervical segments. In thoracic segments, overlap areas were observed in lamina IV, VII, X and intermediolateral n.. In lumbar segments, overlap area of PRV labeled neurons were observed in lamina I, V-VII, IX, X and intermediolateral n.. In sacral segments, overlap areas of PRY labeled neurons were observed in lamina N, V, VII, X and sacral parasympathetic n.. 2. In the brain, overlap areas of PR V labeled neurons projecting to the uterus and Sp6 were observed in lateral paragigantocellular n., rostroventrolateral reticular n., raphe obscurus n., raphe pallidus n., raphe magnus n., locus coeruleus n., Barrington's n., A5 cell group, central gray n., paraventricular hypothalamic n. and arcuate n. This results suggest that overlap areas of PRV labeled neurons of the spinal cord projecting to the uterus and Sp6 might be the first-order neurons related to the viscera-somatic sensory and sympathetic preganglionic neurons. PRV labeled neurons of the brain may be the second and third-order neurons response to the movement of smooth muscle of uterus. These PRV labeled neurons may be central autonomic center related to the integration and modulation of reflex control linked to the sensory and motor system monitoring the internal environment. These overlap areas of spinal cord and brainmay be related to autonomic centers related to regulation of uterus.

  • The data of crown width with 4 directions, DBH, tree height, and coordinate for sample trees were collected from 30 permanent sample plots in secondary fore st of the Maoershan Experimental Forestry Farm, Northeast China. In this paper, the competition of individual trees in stand were discussed for secondary forest by using iterative Hegyi competition index and crown overlap index that represented the competitive and cooperative interactions among neighboring trees. Active competitors of subject tree in the competition zone were selected to calculate the iterative competition index. Using the results of crown classification based on the equal crown projection area, a new distance dependent competition index called crown overlap index (COI) was developed for secondary forest. The COI performed well in describing the crown competition rather than crown competition factor (CCF). The individual-based competition index discussed in this paper will provide more precise for developing individual tree growth models for secondary forest and it can also use to adjust the stand structure for spatial optimal management.

  • This study identified overlap of male innovativeness and of opinion leadership across product class. Product class include clothing, hairstyle and cosmetics, small electronic appliances, large electronic appliances, interior supplies, sports and leisure supplies, and cars. 423 male adults working in Seoul area was surveyed using questionnaire. Results of statistical analysis supported that innovativeness and opinion leadership are not monomorphic but polymorphic across product class. Higher degree of overlap and higher degree of correlationship of innovativness and of opinion leadership exist across product class which share similar characteristics such as clothing-cosmetics, small electronic appliances-large electronic appliances. Innovative communicator ranged from 5.0% to 11.4% in which percentage of innovative communicator was highest in the case of clothing purchase.

  • Focused Ion Beam(FIB) systems is a useful tool for the fabrication of micro-nano scale structures. In this study, the effects of FIB etching on the Au microstructure are systematically investigated. As the fabrication parameters, ion dose, dwell time and beam overlap ratio are studied. First, the increases of Ga ion dose makes the milling yield higher and the sidewall of milling profile steeper. Dwell time is found to have little effects on the milling profile due to the relatively large milling area of $1\times1{\mu}m^2$ used in this study. However, beam overlap significantly affects not only milling rate but also milling profile. As the beam overlap ratio changes from positive to negative, the development of regular cross-stripe patterns at the bottom with low milling rate is observed.

  • The crystallization temperature of an amorphous silicon (a-Si) can be lowered down to 400.deg. C by a new method : Double-metal induced lateral crystallization (DMILC). The a-Si film was laterally crystallized from Ni and Pd deposited area, and its lateral crystallization rate reaches up to 0.2.mu.m/hour at that temperature and depends on the overlap length of Ni and Pd films; the shorter the overlap length, the faster the rate. Poly-Silicon thin film transistors (poly-Si TFT's) fabricated by DMILC at 400.deg. C show a field effect mobility of 38.5cm$^{3}$/Vs, a minimum leakage current of 1pA/.mu.m, and a slope of 1.4V/dec. The overlap length does not affect the characteristics of the poly-Si TFT's, but determines the lateral crystallization rate.

The labeled common locations of the spinal cord and brain were observed following injection of pseudorabies virus(PRV) into the the kidney, UB23 and GB25. Methods : After survival times of 96 hours following injection of PRV, The fifteen rats were perfused, and their spinal cord and brain were frozen sectioned($30{\mu}m$). These sections were stained by PRV immunohistochemical staining method, and observed with light microscope. Results : In spinal cord, PRV labeled neurons projecting to the kidney, BL23 and GB25 were founded in cervical, thoracic, lumbar and sacral spinal segments. Dense labeled areas of cervical segments were overlap in lateral cervical n. and lamina III-V area. Thoracic segments were overlap in lateral spinal n., intermediolateral n. and lamina V-X areas. Lumbar segments were overlap in lamina I-V areas. Sacral segments were overlap in lamina IV, V and X areas. In brain, PRV labeled areas projecting to the kidney, UB23 and GB25 were overlap in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular n./rostroventrolaterai n., raphe obscurus n,, raphe pallidus n., raphe magnus n., gigantocellular reticular n., locus coeruleus, subcoeruleus n., A5 cell group and paraventricular hypothalamic n.. Conclusions : This results suggest that PRV labeled overlap areas of projecting to the kidney may be correlated to shu and mu points related to the kidney. These morphological results provide that organs-shu(transport) and mu(alarm) points interrelationship may be related to the central autonomic pathways.

  • A variable air-gap type system is widely used for inductive precision position measurement systems. This type transducer has high sensitivity but lacks a linear measurement range due to structural nonlinearity. Furthermore, as measurement range increases, linearity error is also increased. The alternative is a variable overlap-area type system. The sensitivity of this type is determined by the initial air-gap dimension, keeps the original value and does not deteriorate linearity in spite of the variations of the measuring range.

  • Two dimensional computer simulations were conducted on percolative structure in which second phases with various short diameter were arranged in matrix phase. In case of prohibiting the overlap among the second phases, the maximum area fraction of second phase arranged in matrix was increased with higher short diameter. In case of allowing the overlap among the second phases, the critical area fraction was increased with higher short diameter and the total number of distributed second phase was decreased. This results represented that thickness variation of short diameter by grain growth on the production processes affect significantly forming the completion path.

  • 본 논문에서는 센서 클러스터에서 액터를 재배치하기 위하여 센서신호 공통 중첩영역을 추출하는 기법을 분석한다. 기존의 액터 재배치 알고리즘은 CH (Cluster Head)와 동일하게 센서들과 연결을 설정하고자 하는 액터를 CH가 있는 위치로 이동시킨다. 이러한 액터의 이동방법은 액터와 CH를 단순하게 결합하여 액터를 재배치하는 것이며, 액터와 CH가 서로 중첩되거나 충돌하는 문제점을 가지고 있다. 본 논문에서는 센서 클러스터에서 CH와 중첩 또는 충돌 없이 액터를 재배치하기 위해 센서신호 공통 중첩영역을 추출하는 기법을 제시한다.

  • This study conducted an analysis of the distribution and status of baby boomer households and trends of turn to farming and returning home. At the same time, the density analysis of land price increase data, building data, and floating population data was conducted in Jeollanam-do County. The established base areas were superimposed to distinguish the regional centers according to the number of superimposed indicators. It is intended to present management measures according to the degree of activation of the center. An area where three bases overlap can be designated as a center activation area, and a place where two regions overlap can be designated as a center semi-activation area. Using the analysis of regional centers at the county level, hierarchies of the centers were classified and management measures were presented. Based on these findings, this study addresses meaningful applicability for regional and medium- and long-term plans.
