  • Six kinds of canned processed fish-balls were collected from the local market of Korea in April, 1975 and frozen section was prepared with the fish-balls at $-25^{\circ}C$ , coincidently stained with PAS, sudan III, carbol-thionine and light green for histochemical observation on evaluation of materials and quality of the porducts. The results tased on morphological analysis were summarized as follows. Protein contents were showed the lowest level, ranging about $2.7-9.0\%$, while carbohydrate was contained from $58.1\%\;to\;75.2\%$ of the highest degree. Fat contents had a great variety depending upon the quality of porducts, showing $1.4-17.6\%$, and air bubble was contained from $14.4\%\;to\;21.1\%$, tended to a large quantity. In sample No. 6, the micro-organism3 were observed around the denaturated prtotein, carbohydrate, and air bubbles in canned fish-ball. When the other samples were incubated for 4 days at $37^{\circ}C$, bacterial colony was also formed around the denaturated protein, carbohydrate, and air bubbles in cavities.

  • Two experiments were executed to investigate the effect of uniform connectedness systematically using the identification task of briefly exposed forms. Previous study observed negative repetition effected (i.e., NRE) in the identification task of two parentheses either connected or disconnected vertically, which was interpreted as an evidence against the hypothesis of uniform connectedness. Experiment I tested the hypothesis that NRE resulted from the Perceptual set or anticipating disconnected displays. Experiment 2 tested the hypothesis that NRE resulted from relatively shorter exposure time. Using partial report task asking participants to report only the cued target and whole report task asking them to report the whole pattern with only connected displays, experiment 1 observed NRE respectively. Experiment 2, with longer exposure time equivalent to 83% accuracy and response bias controlled by use of catch trials, obtained the same NRE. Those results seems to indicate that uniformly connected forms were processed analytically by perceivers without task demand and futhermore, the hypothesis of uniform connectedness as a principle of perceptual organization is not plausible.

  • In this study, homogeneous regions for regional frequency analysis were identified using rainfall data from 61 observation points in Korea. The used data were gathered from 1980 to 2010. Self organizing map and K-means clustering based on Davies-Bouldin Index were used to make clusters showing similar rainfall patterns and to decide the optimum number of the homogeneous regions. The results from this analysis showed that the 61 observation points can be optimally grouped into 6 geographical clusters. Finally, the 61 observations points grouped into 6 clusters were mapped regionally using Thiessen polygon method.

  • Morphology and histochemical characteristics of the alimentary tract in surfperch, Ditrema temmincki were investigated by histological observation. The relative length of gut(RLG) in surfperch, that is the postpharyngeal portion of the alimentary tract, is about 0.89 to standard length. The absence of a stomach, which is the part of expantion of the alimentary tract between esophageal end and the entrance of the bile duct into the intestine, was observed. The alimentary tract is divided into the esophagus, esophageal-intestine part, anterior intestine, mid intestine, posterior intestine, intestinorectum part, rectum, rectal-anus part, and anus by morphology and histochemical features. Morphology of mucosal folds is the most complexity in the rectum and the tunica muscularis of the esophagus and anus is more advanced than those of other parts. The epithelial layers of mucosal folds consist of columnar epithelium except for cuboidal cells of the anterior part of the esophagus. The goblet cells and polysaccharide absorptive cells were observed in the alimentary tract. Nutritive polysaccharide is mainly absorbed by the absorptive cells in the posterior intestine of the surfperch.

  • This study proposed a robust detection algorithm. It detects hands more stably with respect to changes in light and rotation for the identification of a hand shape. Also it satisfies both efficiency of calculation and the function of detection. The algorithm proposed segmented the hand area through pre-processing using a hand shape as input information in an environment with a single camera and then identified the shape using a Self Organized Feature Map(SOFM). However, as it is not easy to exactly recognize a hand area which is sensitive to light, it has a large degree of freedom, and there is a large error bound, to enhance the identification rate, rotation information on the hand shape was made into a database and then a principal component analysis was conducted. Also, as there were fewer calculations due to the fewer dimensions, the time for real-time identification could be decreased.

  • Radical paradigm shift is being expected due to the coming of the so-called intelligent society. In the intelligent society, things or machines are able to use intelligence for the first time in history and this will bring about fundamental changes at every corner of human society. This article analyzes views of the world in order to figure out basic directions of this paradigm shift. A dualistic view of world mediated by technology is suggested for a new world view of the intelligent society, based on comparison of a traditional dualistic view of world between human-nature and a tripartite view of world between human-machine-nature. This article summarizes paradigms of the intelligent society into four ; externalization of intelligence, productivity explosion, platform society, and self-organizing society. These new paradigms will provide lots of benefits such as intelligence augmentation, production capacity increase, and self-organizing effect. But at the same time, it will increase risks of system failure because of loss of human control on technologies. In conclusion, it is argued that human choices and efforts will decide the future of the intelligent society becuase the paradigm shift is value neutral in essence.

  • This study examined a methodology of architectural integrated design education from the design methodology of architects in 1990s, particularly FOA, who thought of architecture as a material organization. Their design method starts from a prototype, which is a technical and material mediator, and processes a number of materials as specific information into an architectural organization. This method is used in the architectural design studio so that the students can integrate the knowledge leant from other classes into architectural proposals. Three case studies show they can successfully organize their proposals with structural and functional materials, which suggests that the FOA's design methodology is a potential solution for architectural integrated design education.

  • As the digitization of maps in Korea has been completed in 1998, local governments begin to apply digital maps for their administrative convenience. In applying GIS to local administration, there are some important aspects to be considered such as technical aspect, organizational aspect and data managerial aspect. Using surveys to local governments, the study examines the implementation factors such as leadership, GIS organizational settings, human and financial resources, and education programs which are related to the applications of GIS to local governments in Korea. As a conclusion, the study proposes that organizational and human factors be combined harmoniously with technical factors from the beginning stage of GIS installation for the successful implementation of GIS applications to local governments.

  • Ten pigs infected with Aujeszky's disease virus (ADY) or hog cholera virus(HCV) were tested for the detection of virus antigens in frozens or paraffin-embedded sections by avidin-biotin-peroxidase complex(ABC) method. Tonsils, spleens, cerebra and buffy coats were examined for the immunohistochemical test. Where ADV antigen was detected by ABC, a dark brown deposit occurred in both the nucleus and the cytoplasm of lymphocytes and macrophages, however, HCV antigen was demonstrated in the cytoplasm of the infected cells. ADV-positive cells were most frequently detected in tonsils and cerebra, whereas, HCV -positive cells were frequently observed in spleens. And buffy coat were also good for both virus detection. The results suggested that ABC method is considered as an excellent and reliable tool for confirmative diagnosis of these viral diseases.
