The topic of 21st century's culture is the appearance of digital media. It made changes as big as the industrial revolution, and our society is now ruled by the digital media. The main objective of this study is to forecast the direction of current visual design education by researching and analyzing how the introduction of digital media is influencing the evolution of visual design's identity, which is an ever changing and developing science. Also, since the rain target of digital media is the young generation, the change in the method of expressing visual language is inevitable In fact, there have been a lot of changes in the methods of creating and distributing visual communication due to the introduction of digital media. In the past, most educational institutions of design had similar objectives, curriculums and teaching methods to provide education that prepares students for practical business. However, in this digital media era, the application and utilization of visual design are uncomparably diversified, and it is generally classified as interaction. The purpose of this study is to find a wat to train visual design professionals in this digital era. For this purpose, this study will identify a new educational system that fulfills the demands of this society by fusing the traditional education and the new digital education, and will suggest what an design education institute that is ahead of the demands of society should be like.

In order to investigate the effects of Ganoderma lucidum on the fermentation of media by Kluyveromyces fragilis KCCM 35458, with 0%, 0.1%, 0.5%, and 1.0% (w/v) of Ganoderma lucidum extract were added to skin milk and fermented in the suspension culture at $30^{\circ}C$ for 72 hours. The pH, acidity, $CO_2$ evolution, alcohol production, number of yeast cells and lactose content were investigated. The results are summarized as follows; 1. As fermentation time advanced by the pH was decreased and the acidity was increased in the media of 1.0% Gnaoderma lucidum extract as fermentation time advanced. 2. $CO_2$ evolution was increased in the all of Genoderma lucidum extract and significantly effect showed in 1.0% extract medium. 3. During 72 hours culturing, alcohol was detected in all Gandoderma lucidum extract media, 1.0% Ganoderma lucidum extract medium showed extremly high in alcohol and shortened fermentation time. 4. The number of yeast was increased more at logarithmic phase and the growth of yeast was more rapid in all Ganoderma lucidum extract especially 0.5%, 1.0% media samples than control. 5. As fermentation time goes by, the lactose content of media were decreased more rapidly in 1.0% Ganoderma lucidum extract medium than control.

The purpose of this study was to optimize the conditions of continuous mixed culture of C.butyricum and R. spaeroides K-7, which were able to produce hydrogen using biomass-dreived substrate. To investigate the possibility of continuous culture, semi-continuous culture was carried out for 20 days. In semi-continuous culture using the reactor system, the replacement rate of fresh medium was 30% of total medium volume for the highest hydrogen evolution. In continuous culture, the optimum dilution rate was determined to be 0.05$h^{-1}$. The continuous culture produced 3.1 times as compared with the hydrogen on batch culture. On the other hand, the continuous mixed culture produced 1.3~2.1 times as much as hydrogen of the continuous monoculture of C. butyricum. When 10g of glucose in the media (1l) was supplied as a carbon source on continuous culture, mixed culture of C. butyricum and R. sphaeroides K-7 increased hydrogen evolution rate. Because considerable amount of glutamate was contained in waste water of glutamate fermentation, utilization of glutamate was examined in mixed culture. As a result of examination, production of hydorgen was slightly inhibited by high concentration of glutamate, more than 20mM, on continuous monoculture of R. sphaeroides K-7. On the other hand, both on continuous monoculture of C. butyricum and on mixed culture of C. butyricum and R. sphaeroides K-7, production of hydrogen was not inhibited by high concentration of glutamate such as 100mM. Hence this suggests that high concentration of waste water can be used as good substrate for hydrogen production on monoculture of C. butyricum and mixed culture of C. butyricum and R. sphaeroides K-7.

본 논문은 OFDM (Orthogonal Frequency Division Multiplexing)기반의 LTE (Long Term Evolution)하향링크 시스템에서 PS (Primary Synchronization)신호를 이용한 잔여 시간동기 오차를 검출 기법을 제안한다. 제안된 잔여 시간동기 오차 검출 기법은 기존의 잔여 시간동기 오차 검출 기법과 달리, 수신된 PS 신호간의 상호상관 값을 이용하여 잔여 시간동기오차를 검출한다. 제안된 기법은 기존의 기법보다 낮은 복잡도를 가지며, 비슷한 성능을 보여주며 이는 컴퓨터 모의실험을 비교하였다.

A multi-channel network(MCN) is an organization that works with video platforms, such as YouTube, to offer assistance to channel owners in areas such as "products, programming, funding, cross-promotion, partner management, digital rights management, monetization/sales, and/or audience development" in exchange for a percentage of the ad revenue from the channel. This paper examines the market trends, business trends, and future evolution of an MCN. It also examines the status of the MCN industry in the media industry and the strategic direction for future industry development.

Upbringing requires an active intervention in the process of children growing up. Convergence in technology and media makes it possible to augment nurturing by making blended infrastructures with new digital resources available in learning environments at schools. A game-based provision of educationally-valuable content within a collective, virtual environment combined with an analysis of events in the game after it has been played (blended nurture environment) may help to better communicate human values especially where old-fashioned discussion methods fail or do not fulfill the promise of effective, educational institution-based methods of bringing up. This is where life sciences, psychology, media, pedagogy and technology (need to) converge.

We investigate driven magnetohydrodynamic (MHD) turbulence by including the effects of expansion and collapse of background medium. The main goal is to quantify the evolution and saturation of strength and characteristic lengths of magnetic fields in expanding and collapsing media. Our findings are as follows. First, with expansion and collapse of background medium, the magnetic energy density per comoving volume does not saturate; either it keeps decreasing or increasing with time. The magnetic energy density relative to the kinetic energy density strongly depends on the expanding or collapsing rate. Second, at scales close to the energy injection (or driving) scale, the slope of magnetic field power spectrum shallows with expansion but steepens with collapse. Third, various characteristic lengths, relative to the energy injection scale, decrease with expansion but increase with collapse. We discuss the astrophysical implications of our findings.

The advent of multimedia as the new media was caused popularization of personal computer and evolution of technology. The age of multimedia instigated the coming of new paradigm. The computer have been changed reality as a human culture to simulation culture. And it have been developed as a connector between real world and cyber space. As a result, a man who have used a computer has a possibility of danger of immersion or addiction. Therefore we must have the media competence.

In the context of the evolution of automation and intelligence, deep learning and machine learning algorithms have been widely applied in aquaculture in recent years, providing new opportunities for the digital realization of aquaculture. Especially, water quality management deserves attention thanks to its importance to food organisms. In this study, we proposed an end-to-end deep learning-based TabNet model for water quality prediction. From major indexes of water quality assessment, we applied novel deep learning techniques and machine learning algorithms in innovative fish aquaculture to predict the number of water cells counting. Furthermore, the application of deep learning in aquaculture is outlined, and the obtained results are analyzed. The experiment on in-house data showed an optimistic impact on the application of artificial intelligence in aquaculture, helping to reduce costs and time and increase efficiency in the farming process.
