Knowledge-based Society has come into fashion after Industrial Society and Information Society. The world is shifting from industry-based capitalism to knowledge-driven post capitalism, which means that knowledge-based Soceity on production, distribution, and utilization of knowledge and information, which thereafter stirs up broad discussions of Knowledge-based Society. With these background, this study analized the theoretical framework and model for The Effective Strategy of Small Venture Business in the Knowledge-based society. In this study, strategies for establishment of Successful e-Business are improving Small Venture Business in the Knowledge-based society

The purpose of this study was to compare the number and percentage of natural killer cell in schizophrenic and major depressive patients with those in normal healthy subjects 15 Schizophrenic patients, 15 major depressive patients and 16 healthy subjects were included in this study There was no statistical difference in the age and sex between patients and control subjects. All of these patients were drug-free for at lest two weeks before this study. The results of this study were as follows : 1) In schizophrenic patients, the number and percentage of natural killer cell of the group with below-mean score of general psychopathology were significantly lower than those of the group with above-mean score(p<.05). The number but not the percentage of natural killer cell of the group with below-mean BPRS score was significantly lower than that of the group with above-mean BPRS score(p<.05). 2) The number of natural killer cell showed statistically negative correlation with generalpsychopathology score or BPRS score(p<0.05). In conclusion, these findings suggest that the number and percentage of natural killer cell is not significantly changed in schizophrenia and major depressive disorder, but in schizophrenic patients, severe psychopathology in the rating scales is associated with suppression of the number and percentage of natural killer cell.

In this paper, we suggest a new encryption system for high speed permutation image processing. We show how to secure attack relative to redundancy in image data. In addition, by applying the proposed permutation algorithm in image data, we show how to solve problems related to scanning sequence and scraming.
熔融 Zn-Cd, Zn-Bi, Cd-Bi系 및 Zn-Cd-Bi系에서 각 成分金屬의 活動度 측정

Activities of the component metal in Zn-Cd, Zn-Bi-Cd alloys have been determined at 823 K by touch instant electromotive force method. The cell employed was ◁표삽입▷ (원문을 참조하세요) Activities of each component metal which obtained by T.I.E. method showed similar tendencies with the compare of the equilibrium concentration cell method. But activities of the noble metals showed small difference in some range. This difference was made from the substitution reactions in the molten electrolyte, and from calculation's error.
