  • EZW (Embedded Zerotree Wavelet) is an efficient algorithm to encode wavelet-transformed image. In this algorithm, each coefficient of wavelet transformed image is given one of the specific symbols and encoded according to its significant priority. In this paper, we analysis the occurrence conditions of symbols in EZW and propose a modified EZW algorithm. In the proposed algorithm, the significance of an IZ (Isolated Zero) symbol is determined by the additional conditions as well as its absolute value. The occurrence of IZ symbols is decreased and the required bits for insignificant IZ symbols is saved, so we obtained good quality of the reconstructed image.

  • The uniqueness of the K-Pop 'idol' culture, which is a key area of its success, can be found not only through the acceptance of diverse cultures and the strengthening of the performance capacity, but also by the effective utilization of new technological environment. As a result, the Korean idol system, which is distinguished from the Japanese idol system, is established. And these systems are evolving with new technological environments. This paper examines the process of evolution of the Korean idol system that adapts to the technical environment through the case of the idol girl group 'IZ*ONE'. 'IZ*ONE' not only achieved rapid success by actively utilizing SNS and new media and producing interactive narratives, but also establishing stable expansion and homogeneity of fandom through interactive rituals. By comparing the evolution and achievement of such a system with the Japanese idol system, we will be able to present the factors of K-Pop success more clearly.

  • The crude methanol extract of the roots of Achyranthes aspera Linn. was investigated for its possible antinociceptive, diuretic and neuropharmacological activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced-writhing in mice comparable to that produced by diclofenac sodium, used as standard drug. The crude extract produced significant diuretic effect at the dose of 500 mg/kg of body weight comparable to that produced by furosemide, used as standard drug. The extract also potentiated significantly the pentobarbital induced sleeping time in mice; decreased the open field score in open field test, decreased the number of hole crossed from one chamber in the hole cross test and decreased the head dip responses. The obtained results provide a support for the use of this plant in traditional medicine and its further investigation.
