The concept of alternative sphere is terminologically various; resistance media, counter media, minjung media, grassroots media, underground media, alternative media, civic media, etc. Each terminology reflect the feature of times and the emphasis of advocator. This article explore the transformation of alternative public sphere and its motive in Korea. In a world, Korea's alternative public sphere has changed as following: resistance media and liberty media in 70', counter media and minjung media in 80', alternative media in 90', and alternative media and civic media in 2000'. The motive of transformation is basically the expansion of civil society and extension of social movement in Korea. As social movement's character has changed, the feature of alternative public sphere has also changed. Minjung movement played key role of social movement in 1980', the alternative public sphere characterized as minjung media or counter media which was based on working class consciousness. After this, According as civil movement have initiative of social movement, the character of alternative public sphere changed by alternative media and civic media. Besides, this article argue that the alternative public sphere of Korea has changed dialectically with social movement.

The authors examine the characteristics of the counter public sphere during the late Chosun era based on three dimensions: historical, ideological, and analytical. The counter public sphere during the late Chosun era was a lively communicative sphere where the common people, who resisted the premodern ideas and foreign power, tried to overcome the oppressing social and political environment. Although the counter public sphere did not continue to grow during the Japanese colonization era, it provided a basis of the independence movement and the ideological ground for the democratic movement today.

The electrolyte, $(HO)_2C_6H_2(SO_3Na)_2H_2O $(Tiron), disperses efficiently alumina powder in aqueous media and stable suspensions with 60 vol% solid loading can be prepared. The strong adsorption of this additive is mainly due to the ability of the molecule to form chelate rings with the particle surface but electrostatic interactions between the surface charge and the anionic dispersant strongly influence the amount of Tiron adsorbed. By using a cationic exchange route to substitute the counter ion which neutralizes the sulfonate groups, new molecules of dispersant have been prepared, either with mineral cations as $Li^+,\; Na+^,\; NH_4^\;+$, or with organic cations as counter ion but organic counter ions lead to less to less viscous suspensions than $Na^+$ in particular when the number of carbon atoms of the aliphatic chain increases from 1 to 3.

In post-industrial society consumption takes a role as a means of acquiring unique lifestyle of style especially for the new generation. The purpose of this study was to identify consumption culture of adolescents in the context of consumerism culture. The use of goods in order to create social distinctions and to establish self-identity was note in is new generation's consumption culture and it was argued that advertising and other media attach images of beauty fulfilment and good life and that they persuade adolescents to have such lifestyle through buying consumer goods. It was also argued that the consumption culture of adolescents is strongly related to the counter-culture or counter-school culture. Implications were discussed with respect to future research area.

The influence of adding counter-ion such as Na+ on the dimerization of the two sulphonated azo dyes, C.I. Acid Red 14 and C.I. Acid Red 17 in aqueous media has been studied spectrophotometrically. The observed hypochromic effect on increasing the amount of salt has been described. The dye concentration range where the dimerization equilibrium is applicable was chosen. No metachromatic behaviour was observed on changing the dye concentration and the amount of salt. This behaviour was attributed to the ability of the counter-ion to disrupt the structure of water as well as reducing the electrostatic repulsion forces between dye anions which will lead to the increase of aggregation tendency of the dye species.

This paper describes experiments made to develop a technique for marking insects and get the informations for ecological studies as a means of tagging flies with radioactive phosphorus, and also to learn the effect on the subsequent generation of flies. Tests were conducted with house flies, Musca domestica L. emerged front the larvae that had reared in a media containing various concentrations of P-32. Radioactivity of the flies was measured with end-window type $(2mg/cm^2)$ Geiger-Muller counter and proportional counter made by Aloka. In following the daily increases in counting rates by 6-day-old larvae it was apparent the larvae in the starting media containing the higher concentrations of P-32 were showing high counting rates. It was found that about 13.2 per cent of the radioactive material remained in the empty puparia after the flies emerged. Radioactivity of the emerged flies decreased gradually and the biological halflife of phosphorus-32 was approximately 6.14 days with considerable variation. A significant amount of P-32 were detected in the abdominal and thoracic sections as compared with other parts of adult. The activity of phosphorus·32 in eggs and larvae produced by adults reared in medium containing 0.2 microcurie or more of P-32 per gram were readily detected with Geiger-Mi·lier counter. On the other hand, the radioactivity of eggs and larvae produced by the treated males crossed with untreated normal females could be only detected in the medium containing more of 2.0 microcurie with G.M. counter. There was no apparent damage to the flies at dosages as high as 0.5 microcurie per gram of medium. For field studies a concentration of 0.5 microcurie of P-32 per gram of artificial medium appears to give adequate labeling for positive identification of flies and their egg masses.

This research is based on the purpose of awaking the importance to publicity of terrorism prevention in the environment of neo-terrorism and presenting the direction of effective publicity activities of terrorism prevention in the counter-terrorism system. Government publicity through public media plays a significant role in promoting people's participation and improving the awareness. So, to strengthen the terrorism prevention in environmental changes of terror occurrence, active method available for people must be found as publicity method of terrorism prevention suitable for high information society. For this method, this research argued first about relationship between police organization and public as counter-terrorism system and about effective publicity methods of terrorism prevention through active erection of these relationships. This research suggested the operation method through introduction of e-CRM and etc, with ultimate purpose about maximizing the publicity effect of terrorism prevention by using as the advantage of internet these days as possible. And needs of information service activities and other administration strategies of publicity of terrorism prevention are suggested through enlarging the distribution scope of governmental counter-terrorism information materials by strengthening the national publicity activities and using media.

A bubble counter was designed and fabricated for the measurement of gas production rate on the basis of number of bubbles produced from yeast fermentor. The sensor was consisted of bubble forming device and electronic signal processing circuitry. The bubble forming device was built with bubble collector and liquid cell to form uniform size of bubble. Bubbles were counted by pulses formed by photo-interrupter circuitry having 8-bit binary latch counter. The gas production rate curves on the basis of bubble counted showed a good agreement to that of growth curves obtained by the optical measurement method. The sensor was succesfully applied to monitoring of the nutrient utilization test with glucose and galactose media.

Today, the structure of terrorist organizations in the form of a variety of network complexity are evolving. However, terrorist organization not combining randomly generated network but preferential attachment a network. So, it's research should be preceded a better understanding about the characteristics and type of terror network for a effective counter-terrorism policy of law enforcement. In addition, the appropriate response strategy have to technique establish in an era of smart media. In particular, homegrown terrorist attacks on unspecified people without boundaries of countries and regions unlike the traditional terrorism. Also, homegrown terrorism are violence and criminal activity by new various of religion, politics, philosophy. Besides the extreme members of homegrown terror networks went grow up through the evolutionary process in the age of smart media. Law enforcement agencies must identify the terrorist network at the national level. Therefore, terror networks evolving in the online space, forming a radical homegrown terror organizations have access to the network. Intelligence community track terrorist networks and to block the negative aspects of the smart media outlets should be considered.
