This paper describes a simple delay diversity technique for terrestrial digital multimedia broadcasting (T-DMB) and digital audio broadcasting in a single-frequency network (SFN). For the diversity technique, a delay diversity scheme is adopted. In the delay diversity scheme, a non-delayed signal is transmitted in the first antenna, and delayed versions of the signal are transmitted in each additional antenna. For an SFN environment with multiple transmitters, delay diversity can be executed by controlling the emission times of the transmitters. This SFN delay diversity scheme does not require any hardware changes in either the transmitter or receiver, and perfect backward compatibility can be acquired. To evaluate the performance improvement, laboratory tests are executed with various types of commercial T-DMB receivers as well as a measurement receiver. The improvement in the bit error rate performance is evaluated using a measurement receiver, and an improvement of the threshold of visibility value is evaluated for commercial receivers. Test results show that the T-DMB system can obtain diversity gain using the described technique.

Expanded rice husk (ERR) is different from commercial rice seedling media in chemical and physical properties such as pH, permeability, and water content. This study was conducted to test a possibility of improving rice seedling growth by improving the texture of ERR as a rice seedling medium. The seedling media used were a commercial seedling medium (CSM), rice husk, and ERR 1, 2, 3, and 4 with different expansion degrees. The pH of the ERHs ranged from 6.3 to 6.8. As the expansion rate increased, ERR particle sizes decreased, and water permeability and absorption rates improved. No significant differences in shoot dry weight and rate of maturity were found among the seedlings cultivated in the different ERH media. However, the mat formation of seedling roots became loose as the expansion rates were decreased. Further studies are necessary to determine the cause of poor root growth in ERH media.

Social media comprises a vast and consequential landscape that has been poorly mapped and understood. Hundreds of millions of people have eagerly moved many of the conversations and discussions that compose civil society into these services and platforms. There is a need to document and analyze these social spaces for many academic and commercial purposes. The Social Media Research Foundation has engaged a strategy to cultivate better research into the structure and dynamics of social media. The foundation is dedicated to the creation of open tools, open data, and open scholarship related to social media. It has implemented a free and open network collection, analysis, and visualization tool called NodeXL to facilitate social media network research. Using NodeXL a group of researchers has collectively authored a publicly available archive, called the NodeXL Graph Gallery, composed of network data sets and visualizations from users around the world. This site has enabled the aggregation of tens of thousands of network datasets and images. Use of the archive has led to scholarly research results that are based on the wide range and scope of social media data sets available.

In the 'Society of the Spectacle', Guy Debord argued that modern life was dominated by the commodity form and the false desires it engendered. He predicted in 1967 that culture would become the driving force in the development of the economy by the end of the century, He was sure when culture becomes nothing more than a commodity, it must also become the star commodity of the spectacular society. Fashion, the starriest of star commodities with its seductive fantasy approaches to the viewers occluding the commercial reality. From this point, the spectacular property of the modern fashion can be found. This study starts on the notion that the modern fashion is on the center of capitalist consumer culture and is constructed by spectacle. On this premise, the purpose of this study is analysing the attribute of 'spectacle' and 'keeping distance ￡Tom spectacle' in modern fashion expressed in fashion show, fashion media and fashion store. The fashion houses in the 1990s that recognised the commercial value of shock and spectacle were eager to employ young spectacularly visible named designers. They generated the publicity necessary for sales of perfume, cosmetics, bags and diffusion range of clothes through the visible fashion show and fashion media. In the fashion show and fashion media, fashion goods as the commodity both flaunts and disguises its commercial nature in spectacle. The spectacle on the fashion store is the process turning the commodity into image to arouse viewer's higher interest. In the fashion store, the appearance of the commodity such as space, display, package is considered more importantly than its 'utility value'. Meanwhile, the study also covered the innovative trial to evade the ubiquitous 'spectacle' in fashion area.

The strategies of commercial development have been focused on the economy of scale for a process. The design of media has been recognized as a key in assuring mass production of entomopathogenic nematodes. Media optimization was conducted with insect host, proteins, lipids, and symbiotic bacteria mass. G. mellonella (insect host) produced about 290,000 infective juveniles per one. Complex media produced about 250,000 infective juveniles / ml in liquid culture within 8 days (one generation).

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.
