Smartphones are representative multimedia devices capable of various functions that have emerged due to the development of information communication technologies (ICTs). The popularization of smartphones has changed the way ICTs media is used; consequnetly, it is expected that smartphones will influence family life by changing family communications and time use. However, there is a gap between the empirical research on ICTs media and family. This study explores any correlations in the amount of time spent on smartphones between a husband and wife. We marged 1,444 married couples' media diaries from the 8th Korean Media Panel Survey (2017) to analyze the average amount of time spent on communications and leisure shopping using smartphones. The results show that husbands' time use for communication has increased similarly to wives' time use. In addition, husbands' time use for leisure and shopping was positively related to wives' time spent on communications and leisure shopping. The findings show that the use of smartphones is interrelated within the family and suggested that a family systems approach is needed in ICTs media research. Future studies will provide a deeper understanding of the impact of ICTs media and how families are using a variety of ICTs media devices such as smartphones.

This study analyzes the characteristics of the process of changing content as print media is remediation as video media. By applying the dual logic of remediation, we analyze the process of remediation analog media(print) into new media(video). Through the results, we present the possibility that remediation methods using changes and variations in various media can be applied to the design methodology. Marvel Comics has been remediationed as Marvel Cinematic Universe. By understanding the phenomenon that analog media is remediation as new media, Design methodologies can be presented so that designers can derive the results by using the characteristics of remediation when designing.

Consumer innovativeness plays a vital role in explaining consumer dynamics, such as adoption, usage, and behavioral intention, in the new world of disruptive online media. This empirical study aimed to examine the importance of consumer innovativeness and digital literacy in the adoption and expansion of new technology-based media services, focusing on OTT services. Extending the theory of adoption of new technologies by innovators to new media environment centered on OTT services, it examines the influence of the four dimensions of motivated consumer innovativeness on OTT service usage. The Korea Media Panel Data of 2019, where overall ICT usage and media consumption of a broad panel of respondents was collected, was used for the analysis. From the data of 10,864 respondents, 4,031 (37.1%) were found to have experience in using OTT services. To clarify the mediating effect of digital literacy on the correlations between cognitive innovativeness of consumers and their use of OTT services, Process Macro Model 4 was used. The bootstrap method was applied to reveal that all four dimensions of consumer innovativeness have a significant indirect effect on new media usage through digital literacy, thus indicating how digital literacy plays an important role in the spread of new digital services in addition to consumer innovativeness. The findings are important in that they can help in the efforts to introduce new technologies to the public and educate them to improve their digital literacy so that they can enjoy the complete experience of using these new digital products.

The primary objective of this study is to investigate the effect of media on the performance of biofilters. Two types of experiments were carried out in this study. The first type of experiment used a biofilter with the media composed of three different packing materials of compost, peatmoss and GAC(granular activated carbon), whereas the second type used a biofilter with the media composed of compost only. It was found from the two experiments that the biofilter composed of compost, peatmoss and GAC showed better performance than the one composed of compost only with the higher toluene removal efficiency, lower pressure drop, and more uniform media moisture content. In particular, no appreciable media compression occurred for the biofilter composed of compost, peatmoss and GAC, whereas significant media compression took place in the biofilter composed of compost only. As suggested by the other researchers, it is likely that GAC may be responsible for the higher toluene removal efficiency in the case of the biofilter composed of mixed media especially for the early stage of biofiltration due to its adsorption capability of toluene of such high concentration as 300 ppm. It was also regarded that GAC may playa major role in maintaining lower media pressure drop in the case of the mixed media than the media with compost only because of its mechanical strength resisting to the compression. Nonetheless, further refined experiments may need to draw more accurate conclusion. The results of the additional test run using the same mixed media showed that the biofilter system using the mixed media can be consistently operated for more than 100 days very stably despite sudden change in operating conditions of temperature and flow rate.

User Generated contents(UGC) interchange with internet users actively in Web2.0 environment. According to growth of content sharing site, the number of non-expert's contents increased. But non-expert's contents have a simple media just recorded. For providing actual feeling like effects and actions to non-expert's contents, we suggest Fusion Media Middleware(FMM). The FMM can increase user satisfaction by providing actual feeling. Furthermore, The content changes advanced media that has emotional impression. The FMM for providing actual feeling classify the inputted media as a scene based on MPEG-7. The FMM provide an actual feeling to simple media by inserting effects like a sound, image and text among the classified media. Using the BSD code of MPEG-21, the FMM can link up with inputted media and effects. Through the mapping BSD code the FMM control synchronization between media and effects. In this paper, Using the Fusion Media Middleware, the non-expert's contents express value as multimedia that has an actual feeling. Futhermore, the FMM creates flow of new media circulation.

Feasibility of microbial culture media using by-product of salt fermented kanary was investigated. Gram negative strain, Escherichia coli, and Gram positive strain, Bacillus subtilis, and bioluminescent Photobacterium Phosphoreum were incubated with kanary by-Product media (KB media). Compared with LB media, KB media had enough carbon source, but lacked nitrogen source and growth factor. When 0.5% of peptone as a nitrogen source and 0.3% of yeast extract as nitrogen and growth factor source were fortified in KB media, the cell population rate was similar to LB media. Also, when 0.5% of yeast extract was fortified to KB media, it showed the same result as in LB media. The price of KB media with fortification of 0.5% peptone and 0.3% yeast extract, and 0.5% of yeast extract is only 46 and 19% of that of LB media, respectively. These results showed that kanary by-Product could be a good and cheaper bacterial culture media if small amount of nitrogen source and growth factor were added.

Large amount of sludge have been generating in the process of water and wastewater treatment in urban area, and it has been making many environmental problems. Currently almost of sludge is landfilled, and since sludge is difficult to handle and dehydrate, the permeated water from the filled-in ground contaminate the surrounding soil and groundwater which may cause serious environmental and sociological problems. The organic component in sludge can be almost removed through the heat treatment process, and the final product is called artificial soil or artificial media according to the temperature control. To produce artificial media using sludge, chabazite and lime were used as an additive, and the mixture of sludge & additives was thermally treated in the firing kiln at about 800~1, 100。C for about fifteen minutes. The physical and chemical characteristics of the produced artificial media were analyzed, and it showed that it can be used as an artificial media for plant production or soil conditioner for farmland. The concentrations of the toxic heavy metals in the artificial media were lower than the soil quality standard for farmland. The characteristics of produced artificial media, using the mixture of sludge and additives through the heat treatment, is similar to the natural chabazite and soil. The analyzed result of the mineral composition of artificial media showed that it has a characteristics similar to natural stable soil, so the produced artificial media may be applied to farmland or water culture without causing adverse effect. Therefore this study showed that the above process can be a feasible alternative for sludge treatment.
