  • The transverse electromagnetic (TEM) cells are widely used for electromagnetic compatibility (EMC) testing and field probe calibrations. We propose the verification of TEM mode with statistical method using a four-port TEM cell. The verification results are compared with Normal, Rayleigh, and Gamma distribution. As a result, the 75 % quantile of the Rayleigh distribution is excellent agreement with the true quantiles for a number of calibration points.

  • Traditional broadcasting environment is merged with various interactive broadcasting services, and the users use these services through Set-Top-Boxes. But they have limited user interfaces, which are not suitable for TV environments by adopting internet formats. Therefore, this paper suggests a User Navigating Interface which helps the audiences to select and watch their favorite channels more effectively. Firstly, this paper analyzes EPG interface - the most basic service in interactive broadcasting. Secondly, it suggests a user interface and service structure suitable in the network-integrated TV environment.

  • This study focused on effective decomposition methods for low concentrated organic compounds from the reuse of industrial wastewater, and confirmed the possibility through photocatalyst media. Photocatalyst immobilized media was developed to carry on this experiment which confirmed the removal possibility of low concentrated organic compounds. Considering the stability and efficiency of photocatalyst immobilization, inorganic support, hollow bead, and $TiO_2$ nano powder were used. As a result of the removal experiment, the removal efficiencies of acetonitrile, ethanol, IPA(Isopropyl alcohol), methanol were above 75% after 15 minutes while those of acetone, acetaldehyde, urea were 10%, 45%, 20%, respectively after 60 minutes. If further studies were made to increase the surface area of the photocatalyst immobilized media, the efficiency of the removal of low concentrated organic compounds can be improved and this solution can also be used in an actual treatment process.

  • Forming perceptions and having experiences through digital media is becoming more common than having in-person relationships in digital media environment. This study, which was conducted when Fashion Week transitioned to a digital platform in 2020, focuses on fashion shows that are announced through social media. The purpose of the study is to explore how traditional fashion media change through social media and what their media characteristics are from the perspective of remediation, which has been suggested by Bolter and Grusin (1999) as the logic of change in the new media. The results of the case analysis in this study, based on the definition and logic of remediation outlined through a literature review, are that social media fashion shows are remediated from traditional fashion shows in the manner that they are represented, improved, refashioned, and absorbed. The characteristics of remediation expressed in social-media-based fashion shows were derived from repurposed video content, improved the elements of fashion shows to express the shows in various ways, expanded places within the fashion shows, and decontextualized and visually flattened spatial discontinuity, and from genre transitions and perceptual shifts. Social-media-based fashion shows are becoming a tool to renew the fashion experience and views of fashion and strengthen the authenticity of the brand by interacting with the audience, improving on the spatial limitations of traditional fashion shows, and diversifying fashion presentation methods.

  • Objective of this research was to determine the effect of application rate of a slow release fertilizer (SRF) in three root media, peatmoss+vermiculite (1:1, v/v; PV), peatmoss+composted rice hall (1:1, v/v; PR), and peatmoss+composted pine bark (1:1, v/v; PB), on growth and nutrient contents of potted chrysanthemum 'Lima Honey'. All media contained polyacrylic acid sodium salt at a rate of $4.5g L^{-1}$. The fresh and dry weights at 43 days after transplanting did not show statistical differences among treatments in each root media. Elevated application rate of SRF increased fresh and dry weights at 80 days after transplanting in PV and PB media, but not in PR medium. Elevated application rates of SRF resulted in the increase of tissue phosphorus content and decrease of tissue Ca, Na, and Zn contents at both 43 and 80 days after transplanting. Elevated application rates of SRF resulted in the decrease of pH and increase of EC and concentrations of ${NO_3}^-$ and ${P_2O_5}^{3-}$, K, Ca, and Mg in the soil solution of PV and PR media. The trends of those in PR media were also similar except ${NO_3}^-$. The differences among treatments in EC at 80 days after transplanting were less significant as compared to those at 43 days after transplanting in three media.

  • This study identifies correlations between the use of media devices, communication ability, and executive function difficulties for third grade students, as well as investigates the moderating effect of a child's communication ability. Data from the 10th (2017) Panel Study on Korean Children [PSKC] was employed (N=557). Descriptive statistics, Pearson's correlation and hierarchical regression were used along with SPSS 25.0(IBM Co., Armonk, NY, USA). The results were as follows. First, the executive function difficulties in the third-grade showed a significant positive correlation with media device use. While also, showing a negative correlation with a child's communication ability. Media devices use and communication ability has a significant negative correlation. Second, a child's communication ability has a moderating effect in relation to the use of media devices and executive function difficulties. The difficulty of executive function showed a reciprocal increase to a child's use of media devices and indicated a discriminatory effect of a child's communication ability. In conclusion, this study shows that communication ability is important as a personal factor for children who control the negative effects of media devices. Therefore, it is necessary to provide and support an environment for the development of a child's communication ability.
