Developing smart cities increasingly relies on metaverse technology. This has become much more apparent in the post-COVID-19 pandemic urban environment. The demand for fast processing of huge amounts of data and the convergence of various media types is essential for keeping city residents well-informed and safe. This paper builds on recent research on metaverse, smart cities, and digital outdoor advertising media. It proposes that "space culture media", which collectively functions by using physical or virtual spatial information, will play a key role in the smart city, functioning as an augmented city. Specifically, this paper deals with significant issues related to the smart city changes created by tecoration, a metaverse urban media space facilitated and enhanced through digital outdoor advertising.

This research analyzed domestic newspapers' agenda setting trend and meaning construction process on the issue of marine environment by year. The research conducted a language network analysis and used R program and Netminer program to analyze four major daily newspapers' news coverages (Dong-A, Joongang, Hanhyoreh, and Kyunghyang) for the last ten years (2005-2014). The results show that the issue of marine environment in Korean media reports are signified in the economic context. For the last ten years, news reports are mainly focused on the 'development' issue of marine environment, without distinction of year. The core key words of the networks are "development", "plan", and "project." However, diverse strategies for 'preservation' are not covered in media reports as a major issue. The importance of effective preservation and reasonable development should be considered in a balanced way. Korean media coverages mainly concentrate on the development issue, and it has a strong influence on considering the marine environment area as an object of development. Future direction and implication of the press reports related to marine environment are discussed.

Feasibility test for a biofilter was performed to treat VOCs. The applied loading rate to the biofilter was calculated between 60 to $3,700\;kg\;COD/m^3$. Trimethyl-pentene and trimethyl-hexene were the two most dominant compounds and they occupy about 85 percent. During the acclimation period, it is desirable for a biofilter to receive relatively lower VOCs concentration and flow rate, until it can adjust to new substrate and operational environment. Temperature at various points inside the biofilter reactor was observed with more than 23 temperature sensors. With steam heating, temperatures of the top sections of the media were greater than those of bottom sections. Without steam heating, intermediate stages generally had higher temperature measurement than those of bottom and top stages. Because the pH values for different biofilter materials vary significantly, measurement of the pH for the mixture of different combinations of biofilter materials is necessary. Based on the types and brands of media, the measured pH ranged from 5.38 to 9.10. The range of measured pH of different mixtures with perlite, compost, saw dust, peat moss, limestone, vermiculite was 7.05 to 8.62.

To obtain basic information on the detection of cellulolytic activity in Auricularia auricula-judae, the influences of dye reagent, pH, and temperature were assessed. Chromogenic dye (congo red, phenol red, remazol brilliant blue, and trypan blue) was individually incorporated into a medium containing either carboxymethyl-cellulose, Avicel, or D-cellobiose as a polysaccharide carbon substrate. The other assessments utilized pHs ranging from 4.5 to 8.0 and temperatures from $15\sim35^{\circ}C$. Overall, when A. auricula-judae species were transferred onto media contained Congo red and adjusted pH 7.0 and then incubated at $25^{\circ}C$ for 5 days, the clear zone indicative of cellulolytic activity was more pronounced.

Over the past few years, training professionals have become more pragmatic in their approach to technology-based media by using it to augment traditional forms of training delivery, such as classroom instruction and text-based materials. This trend has led to the rise of the term blended learning. Blended learning, an environment of e-learning, is a powerful learning solution created through a mixture of face-to-face and online learning delivered through a mix of media and superior learning experiences. In this article we design and implement an e-learning environment for blended learning. The environment focused on following factors: learning activity and participation of learners, and real time feedback of instructor.

Daily newspapers are one of the most influential mass media and the news coverage can be used an indicator of social issues and needs. The purpose of this study was to investigate characteristics of physical environment in apartments, and to examine the underlying social ideas. In doing so, the contents of national daily newspapers in the past ten years were analyzed by using frequencies. The study found that sophistication, diversity, and differentiation were drawn as social values that lie in the physical environment of apartments, and the characteristics were related to housing types, space planning and complex layout. The finding shows that the coverage of the physical environment in apartments has been growing, and the increasing attention to the residential environment remains strong and significant.

Purpose As web 2.0 has taken root in the Internet environment, people began to create specific values to produce and disseminate contents on their own. In order to emphasize the personalized media attributes, the concept of self media was derived. In this paradigm shift, self media has emerged that succeeded in commercializing themselves in social media. Taking advantage of the influence of self media will have a tremendous positive impact on management activities such as marketing strategy, brand promotion, customer retention, and profit growth. This study examines the factors affecting the loyalty of self media in Korea and China because the studies in the area of selfmedia is not enough. Design/methodology/approach This study analyzed what factors influenced the loyalty of self-media in terms of Korea-China comparison. The research model was proposed on the basis of previous research papers. Content value, interactivity, ease of access, self-congruity, sympathy, and reputation were used as independent variables. Trust and satisfaction are used as mediating variables, nationality as moderator variables, and loyalty to self-media as a dependent variable. Results As a result, it was found that all independent variables directly influence the loyalty of self-media except interactivity, and interactivity indirectly influence loyalty through trust and satisfaction. There was a moderating effect of nationality between satisfaction and loyalty, but was not a moderating effect between trust and loyalty.

Physical parameters such as porosity and effective porosity are important physical parameters that determine the transfer and movement of water and solutes in porous media. Various methods of determining these parameters have been developed, with varying degrees of accuracy and applicability. Most of the existing methods produce static results. They do not produce instantaneous and real time of porosity and effective porosity in a porous media. In this study, a new permittivity method called Frequency Domain Reflectometry with Vector analyzer (FDR-V) is proposed to determine the porosity and effective porosity of some sand samples in the laboratory. The advantage of the FDR-V method is that it instantaneously determines the temporal variation of dielectric constants of porous media. Then, the porosity and the effective porosity of porous media are computed using well established empirical equations. Results obtained from the FDR-V method compared favorably with results from other permittivity methods such as gravimetric, injection and replacement tests. The ratio of effective porosity to porosity was $85{\sim}92%$, when FDR-V was used. This value compared favourably with 90%, which has been usually quoted in previous studies. Considering the convenience and its applicability, the measurement system of FDR-V permittivity holds a great potential in porous media and contaminant transport studies.

This study was conducted on the visitors regarding their usage and evaluation state of the interpretive media which is utilized as a self-guide environment interpretation for the purpose of accumulating basic data for the park management. A questionnaire survey was chosen and the 275 valid samples among them were analyzed. The socioeconomic and behavioral characteristics of the visitors turned out to be similar with the results from another visitor survey in the same site. Among those who used the interpretive media, the largest proportion(77%) used the information board resources of the park; the usage rate of interpretive labels of woody plants, interpretive signs of cultural assets, and LED signs were shown to be relatively high. The usage of park brochures, park web sites, visitor center exhibits, and bulletin boards were less than 40% each. Visitors were asked to evaluate the importance and performance of the nine interpretive medias using a Likert Scale whose value ranges from one to five. The result recorded averaged above 4, which proved that the respondents were perceiving the importance of all forms of interpretive media greatly. The performance of interpretive media was also evaluated as affirmative, except the visitor center exhibits.
