The studies about automatic pattern detection of the eye and face from the human image acquired by the CCD image sensor have good applicabilities in the industry, home automation, and data communication field. In general, pattern detection method consists of feature based matching and template matching. In feature based matching, the feature vector is extracted with DLM(dynamic linking matching), EBGM(elastic bunch graph matching), HMM(hidden markov model) matching and knowledge based matching using statistical characteristics. In template matching, in general, the template vector is extracted with PCA(principal component analysis). When these method applied in the face and eye detection, each method has its own merits and some disadvantage. Therefore, by combined utilization of SVD(singular value decomposition) and HMM algorithm, is expected that we can selectively make use of each methods advantage and it result in improved detection accuracy. In this paper, we proposed the method for face and eye detection, which was combined by the two algorithms, to be suitable for the high speed image processing using DSP chip or microprocessor. In the beginning, template matching was followed by a template extraction using batch SVD algorithm and then face pattern was classified and recognized by HMM algorithm which is one of feature based matching technique. Finally, eye pattern detection was performed by pattern search neural network utilizing eigeneye image.

Surface and bottom water samples were collected from 10 stations located in the coastal area of Tongyong in April, August and October 2000. Distribution of heterotrophic bacteria, coliform bacteria and fungi in the sea water samples was investigated by measuring the comrresponding viable cell number according to the plate counting method. Heterotrophic bacteria in the surface water counted 3.1×10 exp∼4.0×10 exp (3) cfu ml^1, 2.7×10 exp∼1.2×10 exp (5) cfu ml^-1 and 1.3×10 exp (2)∼7.2×10 exp (2) cfu ml^1 in April, August and October, respectively. The cell number of coliform bacteria in the surface water amounted to 0∼15×10 exp (1) cfu ml^-1, 3.5×10 exp (1)∼5.2×10 exp (3) cfu ml^-1 and 0∼1.8×10 exp (2) cfu ml^-1 in April, August and October, respectively. As for fungi, the cell number in the surface water was 0∼3.0×10 exp (1) propagules ml^-1, 3.0×10 exp (1)∼8.0×10 exp (1) propagules ml^-1 and 0∼2.2×10 exp (1) propagules ml^-1 in April, August and October respectively. The surface water samples from the station 3 in August were added with feed staffs for fish as much as 0.01gl^-1, 0.1gl^-1 and 1gl^-1 and cultured at 5℃, 15℃, 25℃ and 35℃. Microbial cells were not isolated at all when the culturing temperature was 5℃. However, the microbial cell number increased significantly in all the surface water samples containing 1gl^-1 of the feed stuffs when cultured at 15℃, 25℃ and 35℃.

Due to social problems such as the increasing of land price and the expanding of city, buildings require more complex and bigger components and structure. However, the complex and massive building projects need new technology to solve effect of local buckling and the needs for more space. Hence, Concrete Filled Tube Steel (CFT), the tube steel to hold concrete during pouring and curing of concrete procedure, which helps to reduce local buckling and space, was developed. Most researches on CFT might not be focused on the characteristic of concrete filled in tube but structural analysis. However, it is the essential factor to increase the strength of concrete on CFT for having efficient results. Therefore, this paper will describe how to apply CFT into the construction site through examining High Strength Concrete (800kg/cm2), the strength of core, and bleeding during pouring strategy.

초음파 비파괴검사와 관련하여 많은 측정 방법들이 사용되고 있으며, 전형적인 예로서 재료성질 결정, 미시구조 특성 평가, 결함의 탐상 등을 들 수 있다. 이러한 응용에서 속도와 감쇠계수는 가장 흔히 요구되는 초음파 측정 파라미터이다. 본 연구에서는 수침식 펄스 에코방법으로 속도 및 감쇠 측정을 위한 5가지 해석 알고리즘 (럴스 겹침법, 상호 상관법, Fourier 변환, Hilbert 변환, Wavelet 변환)을 소개하였다. 먼저 연속한 두 저면 반사파 사이의 시간 지연 측정을 위하여 펄스 겹침법, 상호 상관법, Fourier 변환에 의한 위상 기울기법 및 Hilbert 변환법을 사용하였다. 주파수 의존 위상/군속도와 감쇠계수는 Fourier 변환에 의한 위상 및 진폭 스펙트럼이 사용되었으며, 이와 더불어 시간-주파수 해석법인 wavelet 변환이 이용되었다. 사용된 시편은 분산을 무시할 수 있는 강판과 약한 분산성을 지닌 기공을 함유한 복합판재이다. 각 측정 알고리즘의 특성에 대해 논의하였으며, 측정된 결과들을 서로 비교하였다. There are many ultrasonic measurement methods that are used in nondestructive testing applications. Some typical applications include material property determination. microstructural characterization, and flaw detection. Ultrasonic parameters such as velocity and attenuation are most commonly required in these applications. The accuracy and repeatability of testing results are dependent on both the hardware used to generate and receive the ultrasonic waves and on the analysis software for calculating these parameters. In this study, five analysis algorithms were implemented on a computer for measuring wave speed in a pulse echo, immersion testing configuration. In velocity measurements comparisons were made between the overlap, cross-correlation. Fourier transform, Hilbert transform, wavelet transform algorithms. Velocity measurement was applied to an isotropic steel sample using the five analysis algorithms. Frequency-dependent phase/group velocity and attenuation were also measured using the Fourier transform and wavelet transform algorithms on a composite laminate containing voids.

The water-soluble cutting oil was used in the type of the mixture of additive lubricant, surfactant, etc., as the organic nutrients, with water. Therefore it was easy to be affected by microbials ; they brought the bad odor by putridity, decreased the cutting property, and destroyed the emulsion phase. In the study using cells, Saccharomyces cerevisiae and Escherichia coli, we studied the effect of concentration and dilution ratio on the growth of cells and the cell growth rate, the pH variance and the change of oil's concentration. The results obtained in this experiment were as follows : 1) The result of test dilution ratio (water:oil) vs. cell growth was that by using E. coli, the growth was better in this order in emulsion type (sample 1) 50:1 > 30:1 > 100:1, and in the soluble type (sample 2) the order was 100:1 > 50:1 > 30:1. The effect of the cutting oil's concentration on the Saccaromyces cerevisiae's was less in this order 100:1 < 50:1 < 30:1 ; the maximum growth was occurred at 100:1. 2) In sample 1 by using E, coli, pH range was changed from 9.5 to 8.0 and refractive index(the cutting oil's concentration) was changed from 1.3327 to 1.3318. And in the test using S. cerevisiae, pH range was varied from 9.5 to 6.2 and refractive index was changed from 1.3330 to 1.3310. In sample 2 by using E. coil, pH was changed to 8.9 and refractive index was changed from 1. 3315 to 1.3313 and in that of using S cerevisiae, pH was changed to 8.1 and refractive index was decreased from 1.3355 to 1.3340.
