For real-time transmission of Nonlinear Terrain Information, a new Neural Network algorithm is proposed. The proposed neural network technique is the real time computation method through the inter-node diffusion. In the network, a node corresponds to a state in the quantized input space. Each node is composed of a processing unit and fixed weights from its neighbor nodes as well as its input terminal. The most reliable algorithm derived for real time transmission of Nonlinear Terrain Information, is a dynamic programming based algorithm based on sequence matching techniques that would process the data as it arrives and could therefore provide continuously updated neighbor information estimates. Through several simulation experiments, real time reconstruction of the nonlinear Terrain information is processed. 일반적인 실상 정보의 전송올 위하여 표본추출 데이터를 이용하여 목표하는 위치까지의 전송기법이 많이 사용되고 있다. 이를 위 하여 저해상도를 가지 는 지형정보시스템에서 고해상도의 원래의 지형 정보로 보간 시키는 몇몇 연구 방법이 수행되었다. 또한 지형의 고도 윤곽 정보에 대한 응용 부분 으로 써, 국토 건설, 도시 계획시의 채광 및 통신 장애 지역 등에 압축된 등고선 지형도 등을 이용하여 3차원 실재 지형도를 복원시켜 사용하였다. 정보 보간 특성을 갖는 기존모텔로 Inverse Distance 기법, TIN (삼각불규칙망) 기법, DT기법 등의 알고리즘을 이용한 기법 등 수학적인 계산 방식 들은 보편 적으로 주위의 정보를 잘 계산해 내지만, 굴곡이 심한 부분 등에 부분적인 오차가 자주 발생되며, 특히 계산 시간이 오래 걸리는 단점을 가지고 있어 불편함이 있다. 이와 반면, 병렬처리의 원리를 이용하는 신경회로망은 내부의 연결강도를 적응적으로 변화시키는 학습성, 병렬성 등의 특성에 의하여 신속하게 계산처리를 하는 보간 기능을 가진다.

The Lateral Information-Propagation Neural Networks is proposed to regenerate the 3-dimensional terrain elevation data from contour lines. Contours in paper map are an expression of terrain elevation in highly compressed form. A real time regeneration of terrain data for each grid points from the contour information is required for various applications. I the proposed neural networks, the elevation information on contours is propagated to neighbor units through updating its output toward that of neighbor units. An interpolation of terrain information is achieved from such computation mechanisn. Terrain data regeneration simulation has been done.

In this paper, new calibration technique of the maladjusted stereo cameras using calibrated pixel distance parameter is proposed. The camera calibration in stereo vision systems is a necessary procedure for correct depth computation. Intra and extra parameters should be obtain to determine the relation between image and 3-dimensional world coordination through calibration experiment. One difficulty is in camera alignment for parallel installation: placing two CCD arrays in a plane. No effective methods for such alignment have been proposed till now. Some amount of depth error caused from such non-parallel installation of cameras is inevitable. If the pixel distance parameter which is one of intra parameter is calibrated with known points, such error can be compensated in some amount. Such error compensation effects with calibration technique of the calibrated pixel distance parameter are demonstrated with some experiments and as a results, the effects of the proposed method that used compensated parameters is three times better than that of uncompensed parameter methods.

Ginseng seedlings of different weight were transplanted into the field of different fertilizing level and the changes in growth and in absorption of some mineral nutrients were investigated. 1. Leaf area and leaf dry weight reached the maximum in the beginning of June and were affected greatly by seedling weight rather than fertilizing level. 2. Dry weight and diameter of root decreased temporarily at the early stage of growth, but were recovered soon and increased conspicuously until late in July, then showed slight increase afterward. The effect of seedling weight was remarkable. 3. Total nitrogen content ratio decreased at early stage of growth, but were recovered soon and increased afterward. At the late stage of growth, content ratio of aerial part(leaf, stem and petiole) decreased while that of root increased. A wide difference of content ratio between heavy and light fertilizing level was appeared in the whole plant except leaf during vigorous growth period. 4. The changing patterns of content ratios of phosphate and potassium were similar to that of nitrogen, but the phosphate content was very low as compared with nitrogen. 5. In case of calcium, content ratio of aerial part increased continuously, but that of root showed low and slight change through the growth period. Magnesium content ratio of aerial part increased along with the progress of growth in light fertilizing level. 6. In total nitrogen, phosphate, potassium and magnesium, rate of plant partial to whole mineral content exhibited that the root shared relatively small part compared with leaf, stem and petiole at early growth stage, but increased continuously along with the progress of growth. Calcium content of aerial part, especially leaf, took relatively large portion all through the growing season.

양단힌지 비대칭 포물선아치의 자유진동을 지배하는 미분방정식가 경계조건을 D'Alembert원리와 평형방정식을 이용하여 유도하였다. 유도된 미분방정식에는 회전관성의 영향을 고려하였다. 위의 미분방벙식을 수치적분하기 위하여 Runge-Kutta Method가 이용되었으며, 고유 진동수 매개변수의 값F를 찾기 위하여 시행착오적 고유치문제가 이용되었다. 상세연구로는 양단힌지 포물선아치의 최저차의 3개의 고유진동수를 해석하였다. 회전관성이 고유진동수에 미치는 영향은 무시할 정도로 작았다. 또한 수치해석의 결과로 고유진동수-아치 지간길이의 관계를 그림에 나타내었다. The governing differential equations and the boundary conditions for the free vibration of hinged ended unsymmetric parabolic arch are derived on the basis of the equilibrium equations and the D'Alembert principle. The effect of rotary inertia as well as extentional and flexural deformations is considered in governing differential equations. A trial eigen value method is used for determining the natural frequencies. The Runge-Kutta method is used in this method to perform the integration of the differential equations. The detailed studies are made of the lowest three vibration frequencies for the hinged ended unsymmetric parabolic arches. The effect of the rotary inertia is analyzed and it's numerical data are presented in table. And as the numerical result the frequency versus the span length of arch is presented in figure.

With a view to increase the yield of farming and foresting, the consumption of agricultural pesticides has been greatly increased. Since DDT has been synthesized in 1938, many organic pesticides have been developed. Among these pesticides, organophosphorous chemicals have been believed to be almost nontoxic because they are not accumulative in tissues or organs. However, some studies have reported quite many cases of farmers and foresters who have been suffered from organophosphorous pesticides, and others have described on the incidence of organophosphorous poisoning ranging 20-45 per cent of acute drug intoxication. This study was in this relevance, attempted to examine the effects of organophosphorous pesticide upon the kidneys. For doing this, four different organophosphorous pesticides (phosphamidon, malathion, diazinon, monocrotophos) being used frequently in Korea, were selected. And Sprague-Dawely rats weighing around 200 gm were divided, for the experiment, into 1) basic diet group (control) and groups of 2) phosphamidon 3) malathion 4) diazinon 5) monocrotophos administered. The basic diet was composed of adequate solid nutrients, and each rat was given orally 15-20 gm of basic diet per day. Organophosphorous pesticides (1/2 of LD??, 1/4 of LD??) were administered to the appropriate group per rat per day 1, 3 times respectively. The kidney has been examined grossly, light and electron microscopically, and the serum cholinesterase, hemoglobin, WBC differential count, BUN and creatinine have also been measured. The results obtained from this experiment were as follows: 1. Hemoglobin is decreased in 24, 72 groups of phosphamidon, malathion, diazinon and monocrotophos administered. 2. In white series, neutrophils are decreased but lymphocytes increased in the groups of phosphamidon, malathion, diazinon and monocrotophos administered. 3. BUN is somewhat increased in the groups of phosphamidon and malathion administered. 4. Serum creatinine is increased in the groups of phosphamidon, malathion and 24 hours groups of diazinon, monocrotophos administered. 5. Serum cholinesterase is significantly suppressed in the groups of phosphamidon, malathion, diazinon and monocrotophos administered. 6. Light microscopically, congestion and focal hemorrhage, swelling and degeneration of the cells of the proximal tubule, and hyaline casts in the tubule are observed in the groups of phosphamidon, malathion administered. These findings are less apparent in diazinon, monocrotophos administered groups than that in the groups of phosphamidon, malathion administered. 7. On electron microscopy, swelling of mitochondria, numerous lysosomes vacuoles observed in groups of phosphamidon, malathion administered are more apparent than that in groups of diazinon, monocrotophos administered. Additionally, disruption of mitochondrial cristae and focal thickening of basement membrane are visible in groups of phosphamidon, malathion administered.
