The media industry influenced by digital convergence is developing in the direction which the media consumers change their passive attitudes for positive participation on the base of the interactivity of convergence media of telecommunication and broadcasting. And content is progressing toward on-demand service which is customer-oriented and open. In light of these findings, interactivity is the most important feature which is able to shift the paradigm of the media industry and critical success factors which should be considered in order to plan the media strategy. This study is aimed at shedding light on the effects of interactivity factors, which are main factors of ubiquitous environment, on consumer's acceptance intention and describing the role of perceived interactivity and awareness of media substitution in the process of formation of acceptance intention..

The purpose of the study was to explore the degree of children's access to media and the relationship between the use of media and language development of Korean-Chinese bilingual children in Yanji, China. Questionnaires were answered by 258 4th graders and their parents. The results showed that the children had an access to a variety of media. The children's use of language(Korean/ Chinese) differed to the type of media： they had more access to Korean language in the use of newspapers/magazines, books, and radio, and to Chinese language in the use of computer. They had comparatively a balanced access to Korean/chinese language in the use of TV. Stepwise regression analyses revealed that the children's access to Chinese language in the use of media, proficiency of a parent's Chinese language, and a parent's affection were related to proficiency of the children's Chinese language. Implications are derived from the use of media in development of bilingualism.

The diffusion of smart media based on Internet has brought great changes on existing media business model. This changes also affect the core competence of jobs in media industry. This study performed two focus group interviews among professionals in media industry. The interviews examined the changes that media professionals recognize in the field and requirement changes to meet the job core competence. The interviews also examined the media education method in university that can respond to the changes in the media industry. Breaking away from the classical theory oriented education, university should develop the curriculum that can support competence required in the media industry. Media education in university should focus on fostering problem solving ability that can work regarding various issues in new media environment.

This study conducted both a content analysis and Q-methods analysis in order to find media coverage and recognition type of users about ubiquitous environment in digital online age. The perception type of this study were divided into four types in all through Q-methodology. Above all, this study investigated three research problems. First, how is the type of the perception divided into the subjectivity by recognition-characteristic on ubiquitous environment in Korea? Second, what is a trait of character in these same or different types? Third, how did news media cover ubiquitous phenomena overall? Fourth, is there any difference between media coverage and audiences' perception about ubiquitous phenomena? The results show that audiences seem to generally follow the frames that mass media provide. In addition, however, the audiences tend to recognize ubiquitous environment based upon their own schema as following four types: 1. Positive Universality Leading Type, 2. Uncertain Prudence Preference Type, 3. Future Cultural Enjoyment Type, 4. Negative Effect View Type. This study suggests that every efforts such as technology and policies that can improve the quality of ubiquitous environment in Korea should be accompanied.

Pollution by chemical substances such as POPs, EDCs and PBTs in the ecosystem has become more complex and varied, increasing the possibility of irreversible damage to human health or the ecosystem. It is necessary to have a exposure assessment in a multi-media environment for various chemical substances is required for efficient management. This study applied MUSEM(Multi-media Simplebox-systems Environmental Model), a multimedia environmental model that can simultaneously evaluate the possibility of exposure of hundreds of chemical substances in order to efficiently manage chemical substances that can have negative impact on human health or ecological environment through environmental contamination. MUSEM executed the modeling for Japan by setting all 47 prefectures of japan as the regional area for 62 chemical substances and the rest of the territory of japan, excluding regional area, as the continental area and made the estimation of concentration among environment media in each administrative area and made the sensitivity analysis on Tokyo area. The results of simulation for chemical distribution showed that most of the target chemicals located in water region. The result of sensitivity analysis for octanol-water partition rate showed that the concentration change of soil in urban/industrial area and sediment in freshwater was high. In the case of sensitivity analysis for degradation rate showed that the concentration change of freshwater, soil in urban/industrial area, and sediment in freshwater was high.

Hot-water extracted natural media were made from raw materials for mycelial culture of Pleurotus eryngii. Poplar sawdust, wheat bran and rice bran were used as substrates for hot water extraction. The mixed substrates of poplar sawdust, wheat bran, and rice bran with 50 : 20 : 30 (v/v/v, PWR523) and 50 : 30 : 20 (v/v/v, PWR532) were optimal for mycelial growth of P. eryngii, respectively. The hot-water extracted natural media from PWR523 and PWR532 showed a rapid mycelial growth and spawn running compared to PDA. There was no significant difference in mushroom yield when the mycelium grown on the hot-water extracted natural media was used as the inoculum source for producing fruit body.

To determine the optimal isolation conditions of the entomopathogenic fungi from soil, we compared their growth characteristics with non-entomopathogenic fungi on agar media containing various concentrations of cooper (II) chloride ($CuCl_2$) or dodine. The result showed that dodine medium is more selective, and the optimal concentration of dodine is determined with $50{\mu}g$/ml. We could isolate several putative entomopathogenic fungi from soil using this, and identify them using ITS analysis. As a result, 64% fungi were identified as typical entomopathogenic fungi. This selective medium may be useful to the rapid and simple isolation of entomopathogenic fungi from soil.

The influence of digital media according to environmental change of multi-media came to have significance more than what we imagine. In accordance with high resolution of HDTV in digital media era, the cautious awareness is required for skin color by the immediate color such as replica of TV color, lighting and clothing. As for the broadcasting makeup expression technique caused by a change in broadcasting environment in the digital media era, the first, There is necessity for natural makeup technique, and for expressing the whole makeup evenly and very delicately. The makeup work gets much more delicate. For the delicate expression, more time is being required than the existing makeup time. Second, Lots of time and manpower are required for elaborate real-object processing on all the production fields such as background set, stage properties, and makeup. Third, Realistic expression is available on the screen. Importance of basic makeup is highlighted. Thus, even the skin care shop came to be prevalent. Development in only HD cosmetics is needed for foundation with fine particle in new material and with diverse colors hereafter. The video-media field is a method that is ignored a sense of distance through vehicles such as camera, picture tube, and several kinds of broadcasting machinery and equipment and that is delivered vividly to viewers through screen, unlike the stage makeup, thereby being needed the makeup technology proper for HDTV according to the changing broadcasting environment and media. The video machinery and equipment are proceeding with being gradually high-tech and precise. Thus, an expert in makeup needs to know common sense on the video machinery and equipment before makeup, and needs to make an effort according to it. And, a follow-up research can be said to be necessary on the advance in makeup method and on more diverse dedicated cosmetics along with a research on color tone proper for HDTV.
