Ever-evolving diverse communication tools bring numerous changes and improvements into the lives of humans. It is extremely important to provide visual information when communicating with consumers in the commercial arena because humans acquire over eighty percent of the information around them through sense of sight. One cannot compete with just sheer quality in today's world. Therefore, the applications of digital technology in the visual merchandising became crucial, for it can dramatically improve the market value. Among these applications is digital signage, a new media for esthetic experience. I strongly believe that this would be a new marketing tool for the brand's distinctive and unique publicity. This research has been conducted in order to find out how the fast-growing digital signage, defined by the contents, has become not just a mere digital video clip but an esthetic merchandising tool that can produce various effective marketing strategies; and to discover the characteristics that this application has brought out in the visual merchandising field of fashion stores' global SPA brands. Based on the market case study, analyses have been made for the digital signage types and strategies regarding the visual merchandising expressive elements and for the effects the digital signage application will have on publicity. According to the results, the digital signage has proven to be informative, diversely applicable and contributes greatly to the increase in sales and to the improvement of company and brand image. Thus, it is much more than just a media tool for advertisement.

Sectors of rice blast fungus, Pyricularia grisea, frequently appeared on potato dextrose agar amended with edifenphos and iprobenfos. Thus, we assessed the sector-forming frequency of isolates of P. grisea and compared the fungicide sensitivity between wild types and sectors against the fungicides. The 905 isolates of the fungus were obtained from rice-growing locations in Korea from 1997-1998. When the isolates were grown on potato dextrose agar amended with minimal inhibitory concentrations of edifenphos (20 ${\mu}$g a.i./ml)and iprobenfos (55 ${\mu}$g a.i./ml), they produced sectors that overcame the effect of the fungicides. Among the 905 isolates tested, 9.0% produced sectors against edifenphos and 5.6%, against iprobenfos. Different sector-forming frequencies were also observed among the 11 locations of Korea. Sectors obtained from the fungicide-amended media generally grew more than their counterpart wild types grown on the media with either edifenphos or iprobenfos, regardless of their origins. In this study, greater relative growth of sectors over wild types of tested isolates can support the resistant characteristic of the fungus to survive against the fungicides. Therefore, the results indicate that the sectoring in rice blast fungus, P. grisea, may play a role in the occurrence of fungicide resistance.

The present study is dedicated to investigate the SH body-as well as Love-waves propagation effects in porous media with uncertain porosity and permeability. A unified formulation of the governing equations for one-dimensional (1-D) wave propagation in anisotropic porous layered media is presented deterministically. The uncertainties around the above two cited parameters are taken into account by random fields with the help of Monte Carlo Simulations (MCS). Random samples of the porosity and the permeability are generated according to the normal and lognormal distribution functions, respectively, with a mean value and a coefficient of variation for each one of the two parameters. After performing several thousands of samples, the mathematical expectation (mean) of the solution of the wave propagation equations in terms of amplification functions for SH waves and in terms of dispersion equation for Love-waves are obtained. The limits of the Love wave velocity in a porous soil layer overlaying a homogeneous half-space are obtained where it is found that random variations of porosity change the zeros of the wave equation. Also, the increase of uncertainties in the porosity (high coefficient of variation) decreases the mean amplification function amplitudes and shifts the fundamental frequencies. However, no effects are observed on both Love wave dispersion and amplification function for random variations of permeability. Lastly, the present approach is applied to a case study in the Adapazari town basin so that to estimate ground motion accelerations lacked in the fast-growing during the main shock of the damaging 1999 Kocaeli earthquake.

This study explored the characteristics of media contents in the past, present and future. Also, it investigated the problems in terms of production of contents and circulation in order to find an effective way of providing contents that can keep pace with ubiquitous environment as well as one source multi use in various platforms and channels. In conclusion, it is viewed easy to expect that content would be the most valuable assets in ubiquitous media environments and the importance of contents will be more growing. Rather than game and enjoyment-related contents, more informative and cultural programs will be more valuable so policy-makers as well as industry need to more cultivate this area. In addition, this study presented the method for copyright protection and suggested that governmental policy fostering independent production should also be followed.

The domestic game market is still on a trend of growth. Particularly, as the demand for mobile games is increased, the mobile version is developed in a growing number of cases even after the launch of the games for PCS. In a bid to search for the effective method of UI design depending on the differences between the platforms, this study analyzed the types of different media in the first place and as the approaches to the UI design based on the affordance concept, implemented on the platform of PCS and implemented on the platform of mobile devices were analyzed as the cases which are the same MMORPG games. Since the differences between the game platforms can cause the variations in the physical size of the screens depending on the environment in which the user interface (UI) is rendered and may often involve the controls implemented by the touch of screens rather than the manipulation based on the keyboard and mouse, they usually give the influences on the direction of UI designs. By analyzing these UI elements based on the affordance concept, it may be possible to find the effective method of UI design in the future.

This study was undertaken to develop an efficient propagation technique for mature Betula davurica. Using aseptic materials taken from in vitro culture, the effects of media and plant growth regulators on shoot proliferation and rooting were investigated. DKW medium turned out to be the best in shoot proliferation among the media tested. Whereas axillary buds were better culture material than apical buds in proliferation of shoots, apical buds were slightly better than axillary buds on shoot elongation. Neither 1 /2 MS nor WPM medium seemed to be suitable for shoot multiplication or elongation. When the explants were cultured on 1/2 MS medium, shoot elongation was retarded by forming big callus at the base. In the case of WPM, shoots could be formed normally, but they exhibited slow growing. NAA was so effective on in vitro rooting that more than 80% rooting could be achieved on half-strength DKW medium supplemented with 1.0 mg/L NAA after 4 weeks in cultures. Ex vitro rooting using elongated shoot was also applicable to rooting and acclimatization. Rooted plantlets were successfully acclimatized in an artificial soil mixture and grew normally. The results demonstrate that efficient mass propagation of mature B. davurica can be done through tissue culture.

As the size of the construction industry becomes larger, there are many tries to change the construction education for growing the pre-engineering who has many directly experience. However, architectural construction education, which requires a lot of practical understanding, is still limited to educational textbooks and field trips. Therefore, this study proposed the development of educational contents which can indirectly experience by combining smart media such as time-lapse, video and animation. Also, we verified the effectiveness of contents developed based on usability, practicality(fitness of education), necessity, possibility of commercialization. We will contribute to enhance the effectiveness of education through building construction education contents that take advantage of contents based on this.

Focusing on native plants that have a high possibility of being introduced as extensive rooftop material, this study was conducted to realize extensive and easy-to-manage rooftop gardens and to raise the utilization of native plants by verifying their growing response to soil media and depth. Its result is as follows: 1) In the case of Chrysanthemum zawadskii, the top growth was better in sandy loam than in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$, but the mortality rate was high, making it unsuitable soil. Regarding soil depth the mortality rate was lower in 10cm than in 5cm, and it grew well in 10cm. When using it for rooftop gardens, it would be desirable to keep the minimum viable soil depth over loom. 2) In the case of Sedium middendorffianum the mortality rate was 0% regardless of soil media and depth making it very suitable material for rooftop garden. Although the flowering rate was somewhat lower in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$ than in sandy loam, the mortality rate was low and the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. 3) In the case of Allium senescens, the mortality rate was 0% regardless of soil or soil depth, making it a very suitable plant for extensive rooftop gardens. Although top growth was poorer in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$than in sandy loam the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. In conclusion the study revealed that suitable species for extensive rooftop gardens are Sedium middendorffianum and Allium senescens. However, Chrysanthemum zawadskii can be utilized greatly when fertilizing is managed regularly in artificial mixed soil over l0cm.

Expectations for the industrialization of cultured meat are growing due to the increasing support from various sectors, such as the food industry, animal welfare organizations, and consumers, particularly vegetarians, but the progress of industrialization is slower than initially reported. This review analyzes the main issues concerning the industrialization of cultured meat, examines research and media reports on the development of cultured meat to date, and presents the current technology, industrialization level, and prospects for cultured meat. Currently, over 30 countries have companies industrializing cultured meat, and around 200 companies that are developing or industrializing cultured meat have been surveyed globally. By country, the United States has over 50 companies, accounting for more than 20% of the total. Acquiring animal cells, developing cell lines, improving cell proliferation, improving the efficiency of cell differentiation and muscle production, or developing cell culture media, including serum-free media, are the major research themes related to the development of cultured meat. In contrast, the development of devices, such as bioreactors, which are crucial in enabling large-scale production, is relatively understudied, and few of the many companies invested in the development of cultured meat have presented products for sale other than prototypes. In addition, because most information on key technologies is not publicly available, it is not possible to determine the level of technology in the companies, and it is surmised that the technology of cultured meat-related startups is not high. Therefore, further research and development are needed to promote the full-scale industrialization of cultured meat.
