  • An adaptive on-line optimization method has been applied to test the ability to maximize the cellular productivity of a continuous methylotroph culture system which was simulated by a variable yield Monod-type model. Optimum dilution rate and productivity were successively obtained and maintained at all times by the algorithm that utilizes steepest descent technique as optimization method and recursive least-square method with forgetting factor as dynamic model identification.

  • The second research of "a study of the evaluation indicators in Korean public libraries’ had as Its major objective the identification of Indicators and broad dimensions of public library effectiveness in Korea. The managers and librarians of the 175 public libraries in the sample were asked to rate the performance of their libraries. Factor analysis was used to derive 11 dimensions of effectiveness. The dimensions fit four different models of organizational effectiveness.

  • The objective of experimental study is to apply simultaneous measurement by PIV(Particle Image Velocimetry)to high_speed flow characteristics within Ginseng washing machine. Three different kinds of flow rate(15,20,27 $\ell$/min)are selected as experimental conditions. Optimized cross correlation identification to obtain velocity vectors is implemented by direct calculation of correlation coefficients. Instantaneous velocity distribution, time-mean velocity distribution and velocity profiles are represented quantitatively at the full-scale region for the deeper understanding of the flow characteristics in Ginseng washing machine.

  • A robust audio fingerprinting method is presented based on segmentation boundaries. In order to obtain robustness against linear speed changes, fingerprint extraction and matching are synchronized with the segmentation boundaries. Experimental results show that the proposed method is also robust against other common audio processing steps including low bit-rate compression, equalization, and time-scale modification.

  • Multilayer neural network using a modified beackpropagation learning algorithm was introduced to achieve automatic identification of different types of aircraft in a variety of 3-D orientations. A 3-D shape of an aircraft can be described by a library of 2-D images corresponding to the projected views of an aircraft. From each 2-D binary aircraft image we extracted 2-D invariant (L, Φ) feature vector to be used for training neural network aircraft classifier. Simulations concerning the neural network classification rate was compared using nearest-neighbor classfier (NNC) which has been widely served as a performance benchmark. And we also introduced reliability measure of the designed neural network classifier.

  • This paper presents the text-prompt method to overcome the weakness of text-dependent and text-independent speaker recognition. Enhanced dynamic time warping for speaker recognition algorithm is applied. For the real-time processing, we use a simple algorithm for end-point detection without increasing computational complexity. The test shows that the weighted-cepstrum is most proper for speaker recognition among various speech parameters. As the experimental results of the proposed algorithm for three prompt words, the speaker identification error rate is 0.02%, and when the threshold is set properly, false rejection rate is 1.89%, false acceptance rate is 0.77% and verification total error rate is 0.97% for speaker verification.

  • In order to monitor the parasites, 303 fecal samples were taken from Korean native goats (n=279) and sheep(n=24) in Chonbuk area. The identification of the parasites were determimed by the fecal examination using the floatation or sedimentation methods and microscopical examination, respectively. The obtained results were summarized as follows ; 1. The detection rate of the parasites from Korean native goats and sheep was 98.2% and 83.3%, respectively. 2. In Korean native goat, mixed infection rate was single 7.5%(21 heads), double 47.3%(132 heads), triple 40.8%(114 heads), quadraple 5.0%(14 heads) and quintuple 2.5%(7 heads). 3. In sheep, mixed infection rate was single 12.5%(3 heads), double 45.8%(13 heads) and triple 16.6%(4 heads). 4. The parasites isolated were identified as Eimeria spp. from 283 heads, Oesophagostomum spp. from 96 heads, Ostertagia spp. from 97 heads, Strongylodes papillus from 97 heads, Heamonchs spp. from 73 heads, Trichostrongylus spp. from 42 heads, Moniezia expenza from 26 heads, Cooperia spp. from 16 heads, Nematodirus spp. from 9 heads, Bonostomum spp. from 9 heads, Paraphistomum spp. from 7 heads, and Fasciola hepatica and Capillaria spp. In 2 heads, in order.

  • We evaluated the hatchability of fertilized eggs from six hybrid combinations of highly valued grouper species inhabiting temperate and warm waters, with the goal of establishing a novel hybrid with enhanced growth and viability during the culturing period in the temperate waters of Korea. Hybrid combinations with red-spotted grouper females exhibited high hatchability with high a fertilization and hatching rate of fertilized eggs and a low deformity rate of hatched larvae. Conversely, hybrid combinations with kelp grouper females had very low hatching rates and very high deformity rates; commercial production of seed from such crosses would be difficult without improving hatchability. The hatchabilities of convict grouper ♀×giant grouper ♂ and kelp grouper ♀×red-spotted grouper ♂ were lower than those of maternal purebreds, but these two hybrid combinations were expected to produce potentially large quantities of hatched larvae. In the above evaluation, promising hybrid combinations were identified for commercial production of seed. For these hybrids to contribute to the development of Korea's mariculture industry, mass production of fertilized eggs and seeds is necessary, along with the development of advanced rearing techniques, such as the identification of a suitable rearing temperature.
