  • In this paper, our proposed system uses the regional Gabor wavelet and Neural Network to implement face recognition similar to human face recognition system, because the Gator wavelet expresses visual recognition system of human mathematically and the regional Neural Network is robust to white noise and partial illumination. This system consists of two stages of building database and recognizing face. One is composed by using the supervised learning of Neural Network. At this time, the Neural Network is applied to the upper and the lower part of face images respectively. The Backpropagation algorithm is used to learn Neural Network. Another consists of calibration of slope of face image, measurement of illumination variant using deviation with average face image and similarity comparison using Euclidean distance measure.

  • We presents a new algorithm for tracking person in video sequence that integrates the meanshift iteration procedure into the particle filtering. Utilizing the nice property of convergence to the modes in the meanshift iteration we show that only a few sample points are sufficient, while in general the particle filtering requires a large number of sample points. Multi-parts of a person is tracked independently of each other based on the color Then, the similarity against the reference model color and the geometric constraints between multi-parts are reflected as the sample weights. Also presented is the computer simulation results, which show successful tracking even for complex background clutter.

  • As part of a larger study of indigenous prokaryotic species diversity in South Korea, various samples from Namhangang were subjected to analyses. Fresh water, underwater sediment, and moss-inhabiting aerobic and anaerobic bacteria were isolated. 22 of the isolates were identified as unrecorded bacterial species in Korea that had ${\geq}98.7%$ 16S rRNA gene sequence similarity with published species. The aerobic strains isolated were Kurthia gibsonii and Massilia plicata. Also identified were four facultative anaerobic strains: Bacillus hisashii, Enterococcus rotai, Paenibacillus vini, and Pediococcus pentosaceus. 16 strictly anaerobic strains were identified as Bacteroides xylanolyticus, Carnobacterium maltaromaticum, Clostridium argentinense, Clostridium beijerinckii, Clostridium butyricum, Clostridium cavendishii, Clostridium diolis, Clostridium frigidicarnis, Clostridium perfringens, Clostridium saccharoperbutylacetonicum, Clostridium sphenoides, Clostridium subterminale, Cutibacterium acnes, Paraclostridium bifermentans, Prevotella paludivivens, and Romboutsia lituseburensis. Based on the examination of morphological, cultural, physiological, and biochemical properties of the isolates, descriptive information of these previously unrecorded species is provided here.

  • In 2016, as part of a larger effort to discover indigenous prokaryotic species in Korea, we isolated the family Deinococcaceae and Planctomycetaceae as unrecorded bacterial species. From the high 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clade with known species, it was determined that each strain was a distinct bacterial species. There are no official reports that these two species have been described in Korea; therefore, the bacterial strains of Deinococcus and Blastopirellula are described for the first time in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

  • In this paper, we introduce the design method using CAE(Computer Aided Engineering) which is profitable in the compatability and standardization of the developed product, and the reduction of construction time and price to develop and design a machine equipment. Particularly, we select the standard model to design or develop from the large machinery to the super precision one, extract the peculiar characters of the model by the close analysis of the physical and technical part, the experiment for the characteristics of objective dimensions by analogical mathematical analysis for previous results, and can induce the design model demanded by user investigating optimal data in the design previous We present the analogical algorithms and process method of design factors and restriction factors in the systematization design with computer. Then we analyze step functions for each systematization equipment and induce the process of technical data with actuator model.

  • Regarding Korean psych-adjectives and their -e ha- counterparts, e.i., [psych-adjective + -e ha-] constructions, what is at issue is how to capture the semantic difference and similarity between the two. Concerning this issue, one of the most controversial and difficult problems is whether the psych-construction has Action (Agency) as part of its meaning. The purpose of this paper is to solve this problem by answering the question why psych-constructions are much more natural when they are used as negative imperative than when they are used as positive imperative. First, in order to figure out why positive imperative is not allowed, we show that.e ha- adds the meaning of non-volitional action to psych-adjectives, using Jackendoff's Conceptual Semantics. Secondly, in accounting for why negative imperative is so natural, we show, with Talmy's Force Dynamics theory, what the speaker requires from the hearer is internal volitional action.

  • In this study, we calculated the genetic relationships of Pestalotiopsis species collected from various places in southern part of Korea through isozyme analyses. As a result, EST showed the largest number of band, and the number of bands were ranged from 5 to 7 on the average. All the isozymes used in this study showed distinctive band patterns for each isolates. Similarities among the compared isolates ranged from 48 to 93%. Isolates SP7, SP19 and SP23 showed more than 90% similarities, and most isolates showed similarities ranging from 65 to 82%.

  • The region containing 18S rRNA gene, ITS 1 and part of the 5.8S rRNA gene of the Atractylodes japonica Koidz was amplified by PCR and the product cloned in a pBluescript SK II plasmid. DNA sequence of the cloned DNA was determined and submitted to the GenBank (accession number EU678363). Phylogenetic analysis of the ITS 1 DNA showed close similarity with the other plant species of the family Compositae. The extract of the plant materials of five different members of the family Compositae was analyzed by HPLC to detect atractylon. Extract of the A. japonica Koidz showed presence of significant amount of atractylon. However, noticeable amount of atractylon was not detected by the same analyses from the extracts of the other plants belonging to the family Compositae including Artemisia capillaris, Chrysantemum zawadskii, Eclipta prostrata or Taraxacum platycarpum.

  • From the plasmid library made from Sstl and San-digested genomic DNA of Streptomyces fradiae NRRL 2702, four positive clones were selected using an oligodeoxynucleotide probe from the N-terminal amino acid sequence of purified threonine dehydratase. The cloned gene for threonine dehydratase was a 2.0 kilo-base pair DNA fragment. The deduced amino acid sequence of PCR product (PCR245) was matched to that of the N-terminal part of threonine dehydratase from S. fradiae and this showed a high similarity to the threonine dehydratases of other organisms. This indicated that amino acid sequences of threonine dehydratases were highly conserved and the polypeptide product of the PCR245 was likely to be involved in the deamination of threonine.

  • In this paper, we consider the H$\infty$ tracking control of linear system with a limited actuator capacity. The considered reference is a general time-varying one with bounded magnitude and rate. By adopting a similarity transform and a new sto variable, we convert the original system equation to new one which has a tracking error as a part of the new state variable. First, we obtain a result on the low-gained H$\infty$ tracking control which never permits the actuator saturation. Next, we give a result on scheduled H$\infty$ tracking control which uses the actuator capacity more effectively. All results are in the form of linear matrix inequalities(LMI) which can be easily checked their feasibility. Finally, we give a numerical example to show the validity and usefulness of our results.
