Application of polyacrylamide gel (PAG) instead of agar to solid cultures of Streptomyces spp. was studied. The improved media were prepared by 1) gelling 20 ml of 5% acrylamide in a glass petri dish at room temperature, 2) washing by running water for more than 8 hr to remove residual reaction reagents, 3) drying at 5$0^{\circ}C$ for 12 hr to make a gel film, 4) autoclaving at 121$^{\circ}C$ for 15 min, and 5) swelling gel for about 4 hr by adding sterile liquid medium. In PAG media there were no differences from the observation of morphological characteristics showing during the cellular differentiation on agar media, whereas the ability to utilize carbohydrates differed somewhat from agar media. Agar media thus were little favorable for biochemical tests which the growth was determined depending on the formation of colony, but washed PAG was superior to serve as a solidifying agent.

The media compositions and culture conditions were optimized for mycelial growth of Coriolus versicolor and Lentinus edodes. Media composition for optimal growth of Coriolus versicolor was 2.0% glucose 0.4% peptone and 0.6% yeast extract. Media composition for optimal growth of Lenttnus edodes was 2.0% glucose 2.0% starch 0.4% bacto-soytone and 0.6% yeast extract. The media supplemented with KH2PO4, 0.046% KH2PO4 0.1% and MgSO4, .7H2O 0.05% supported better mycelial growth than the media without mineral salts. The optimum temperature for mycelial growth ranged from $25^{\circ}C$-28$^{\circ}C$. The optimum pH range for mycelial growth of Coriolus versicolor was 5.2~5.6 while that of Lentinus edodes appeared to be 5.75.

Recently, as social media users have grown, the resulting form of advertising has emerged, and one of the types is native advertising. This advertising method appears to be 52% higher than the banner, according to a study by the IPG Media Lab (2013). Therefore, there is a positive effect on native advertising, but it is necessary to maximize the effect. In this paper, the acceptor's attitude to the native advertisement and the shared intention are verified as to how the effect of the native advertisement can be understood and the maximized effect can be obtained. When the brand phrase was in the form of direct exposure, the subjects were positive about the advertisement and the brand attitude was favorable. Share intentions were also high. These results included suggestions to produce native advertisements in consideration of the attitudes and sharing of the recipients.

Media art, which is a combination of media technology and art, is making a lot of progress in combination with AI, IoT and VR. This paper aims to meet people's needs by creating a video that simulates the dance moves of an object that users admire by using media art that features interactive interactions between users and works. The project proposed a universal image synthesis system that minimizes equipment constraints by utilizing a deep running-based Skeleton estimation system and one of the deep-running neural network structures, rather than a Kinect-based Skeleton image. The results of the experiment showed that the images implemented through the deep learning system were successful in generating the same results as the user did when they actually danced through inference and synthesis of motion that they did not actually behave.

With the diversified development of modern art, the application of mixed media in painting has become increasingly prominent, which not only provides artistic creators with new creative ideas, but also magnifies the creators' emotions and re endows the media with meaning and value. This paper systematically introduces the definition, features and connotation of mixed media painting, and expounds three aspects of the aesthetic function of multimedia in oil painting creation, the embodiment of painting individuality, and the combination and application of materials and technique to demonstrate that mixed media presents different understanding and expression in Chinese oil painting, no longer constrained by traditional oil painting materials, which promotes more development possibilities of the art expression form of Chinese oil painting, enhances its international influence, and bring new vitality to the creation and development of Chinese oil painting.

Background: The isolation of non-tuberculous mycobacteria (NTM) has been increasing in South Korea. To date, however, the cause of this increase has not been determined, and it remains unclear whether the use of liquid media has contributed to this increase. The aim of this study was to evaluate the factors associated with NTM isolation and the impact of liquid media on NTM culture. Methods: Mycobacterial smear/culture results of respiratory specimens (sputum and bronchial aspirates), obtained during the years 2002, 2005, and 2010, were retrieved and analyzed retrospectively. Results: During the years 2002, 2005, and 2010, 83,096 sputum specimens were collected from 31,104 patients, and were cultured for mycobacteria, using solid media only in the 2002 and 2005 specimens and both solid and liquid media in the 2010. Of these, 3,516 (4.2%) specimens were smear-positive for acid-fast bacilli (AFB). The annual rate of NTM among positive culture specimens increased from 21% in 2002 to 57.8% in 2010 (p<0.001), as did the proportion of NTM, among AFB smear- and culture-positive specimens, from 12.2% in 2002 to 45.2% in 2010 (p<0.001). In 2010, the NTM culture rate was higher in the liquid than in the solid media (13.9% vs. 8.4%, p<0.001). The NTM rate among AFB-positive specimens was higher in patients aged >50 than ${\leq}$50 years. Conclusion: The rate of NTM isolation has steadily been increasing at the hospital in South Korea, likely due in part to the use of liquid media for the culture.

This study was conducted to find out the commercial in vitro propagation methods through protocom-like bodies (PLB) induced from shoot tip culture of Miltonia spp. Among several culture media for induction PLB from shoot tip in Miltonia spp., MS basal medium was better than Hyponex, Vacin & Went basal medium and other media supplemented with natural additives. PLB's proliferation and differentiation in Hyponex medium including $20g{\cdot}L^{-1}$ banana + $20g{\cdot}L^{-1}$ sucrose(pH 5.2) was better than in MS medium. It was tendency that solid media showed higher PLB fresh weight than liquid medium or other cotton bridge culture. The dark culture for 1~2 weeks and adding $10{\sim}20g{\cdot}L^{-1}$ sucrose on hyponex basal medium was the most effective to increase the PLBs growth and shoot number.

This paper proposes an arts and culture content creation tool powered by artificial intelligence. With the recent advances in technologies including artificial intelligence, there are active research activities on creating art and culture contents. However, it is still difficult and cumbersome for those who are not familiar with programming and artificial intelligence. In order to deal with the content creation with new technologies, we analyze related creation tools, services and technologies that process with raw visual and audio data, generate new media contents and visualize intermediate results. We then extract key requirements for a future creation tool for creators who are not familiar with programming and artificial intelligence. We finally introduce an intuitive and integrated content creation tool for end-users. We hope that this tool will allow creators to intuitively and creatively generate new media arts and culture contents based on not only understanding given data but also adopting new technologies.

In this modern digital era, there are very vigorous arguments about digital and media aesthetics throughout culture and art on the basis of new transferring of recognition about the art-media's characteristics. Therefore, this paper tries to discover the art-media's characteristics and aesthetic value that are included in contemporary digital fashion through studying the fusion between digital and fashion. The purpose of this research is to offer positive and evolutive opportunity of artistic thinking to make the meeting between fashion and media suggest the future generation, adaptation and recognition in the media - developmental environment that will be deeper and more fueling. In the area of research method, this paper takes the method of theoretical research by referring national and foreign literatures and preceding research-papers, and carries out investigation and analysis about digital fashion for the last 10 years. The results of this study; The art-media's characteristics of modern digital fashion are virtuality, immateriality and characteristics of multimedia. The aesthetic values can be classified with four kinds of properties. First is hybridity initiated from multi-media that creates works; the second is infinite reproductivity initiated from the characteristics of the multi media and the digital carrier. Thirdly, there is also interactivity appeared all over the area of production, adaptation and perception caused by non-linearity and immateriality. Finally there is synesthesia that can extend the capability of sense through digital media.
