As a direct-view flat panel displays, there are many devices, such as plasma display panels(PDPs), vacuum fluorescent displays (VFDs), and light emitting diode(LED). Among these, a PDP is the first type of panel display to be made commercially available. A 'Plasma display' is the general term for a flat display utilizing the light emission that is produced by gas discharge. However, the brightness and Luminous efficiency are still not adequate for consumer television. So, the new sustain electrode type of ac PDP was proposed. By arranging the transparent electrode of quadrangle by zigzag, the area of electrode are reduced, and the length of electrode gap is increased. It generates a high luminous efficiency(corresponding to a 40% improvement of standard type), the same discharge voltage characteristics, and the low power consumption at same luminance.

The emergence of a growing number of tall buildings, often with unusual shapes and innovative structural systems, has led to the realization of the need for and the importance of field measurements. The new China Central Television (CCTV) Tower in Beijing is one of tall buildings with a highly unusual shape and a complex structural system, requiring field measurements to identify its dynamic characteristics for the subsequent dynamic analysis of the tower under wind excitation, seismic-induced ground motion and traffic-induced ground motion. The structural system and the finite element model of the CCTV Tower are first introduced in this paper. The computed natural frequencies and mode shapes are then presented as a reference for the field measurement. After introducing the arrangement of the ambient vibration measurement, the field measured natural frequencies and damping ratios of the CCTV Tower are presented and the measured natural frequencies are finally compared with the computed ones. It was found that the structural damping ratios of the CCTV Tower are small and the computed natural frequencies are smaller than the measured ones by about 12~17%.

This study investigated current status of lighting environment, residents' awareness of lighting and lighting use according to behavior in the living room of apartment to determine current lighting trends and their related problems. The living rooms of newly-built apartment units(133~165[$m^2$] and larger than 166[$m^2$] within the past five years) were examined. The results are summarized as follows. 1. Resident satisfaction with current living room lighting was the highest in 'illumination' and the lowest was 'energy savings' regardless of the size of living room. 2. This kind of ceiling lighting layout, 133~165[$m^2$] unit used central lighting and larger than 166[$m^2$] units used central lighting and cove lighting. Regarding light sources, 133~165[$m^2$] linear FL, halogen, larger than 166[$m^2$] bulb-type FL are widely used. LED are now being found in the living room corridor and kitchen walls of newly-built apartment houses. 3. Watching TV and reading books were commonly behaved in the living room. Conversations between family, having desserts, resting, housekeeping, and entertaining were usually done weekdays, while having desserts and conversations between family were done weekends. Use of lighting as main behaviors is properly and differently required due to the distinct uses of lighting as residents' behaviors or their life style.

Single-phased $CaZrO_3:Dy^{3+}$, $Tm^{3+}$ series have been successfully synthesized by solid-state reaction, and their luminescence properties were investigated. Under 355 nm excitation, $CaZrO_3:Dy^{3+}$ series showed characteristic emission of $Dy^{3+}$, which exhibited yellowish white color. By introducing $Tm^{3+}$ into the matrix, the emitted hue of the $Dy^{3+}$-doped sample could be easily tailored to white, and simultaneously, energy transfer from $Tm^{3+}$ to $Dy^{3+}$ was observed. The color coordinates of the optimum white-emitting sample were (0.321, 0.323), which were very close to the data of the National Television Standard Committee (0.33, 0.33). The co-activated phosphors presented good match to ultraviolet light-emitting diodes (LEDs), which revealed that they could be novel promising phosphors utilized in white LED application.

This study measured the effects of fake news and propaganda on managing information on COVID-19 among the Nigerian citizenry. This study examined sources of information on COVID-19 available to the people, evaluated reasons behind spreading fake news, examined how fake news has affected the spread of COVID-19 pandemic in Nigeria, established the consequences of fake news on managing COVID-19 pandemic and as well identified ways to contain fake news at a time like this in Nigeria.It is a survey with a sample size of 375 participants selected using simple random technique. Instrument of data gathering was questionnaire widely distributed in the six geo-political zones of Nigeria using Survey monkey. Data was analysed using frequencies, counts and percentages, tables and charts. Findings revealed that people rely more on radio, television, and social media for information on COVID-19. Fake news is spread by people mostly for political reasons and intention to cause panic. In Nigeria, fake news has led to disbelief of the existence of the virus thereby leading to violation of precautionary measures among the citizenry and lack of trust in the government. Concerted effort on the part of the government is required to give public enlightenment on the danger of fake news. Also, directorate of anti-fake news should be established to censor and reprimand sources of fake news. People should always check source of information to confirm its credibility and be weary of sharing unconfirmed information especially on the social media.

Purpose: The purpose of this study is to understand fans' perception of the MLS. Particularly, this study investigates both the avid fan's perception of the MLS as well as the same perception in a potentially larger audience. This study aims at (1) segmenting the findings into three groups, (2) understanding the characteristics of these groups from the sport marketing prospective and (3) comparing the three groups to see whether there are any similarities and differences. Research design, data, and methodology: Using motivational factors alongside the 4P's of marketing, these three segments were analyzed and their similarities and differences were compared. An online survey was created and distributed through different MLS databases. Results: Prior to the distribution, a few hypotheses were made regarding the motivational factors of fans; specifically, that the quality of play has led to a lack of interest in the league and that the presence of star athletes has the potential to bring in more fans for the league. The quality of play and star athletes are important and thus a bigger emphasis needs to be placed on the designated player rule. At the same time, more television coverage as well as more exhibition games with international teams can generate more buzz for the league and garner more fans. Conclusions: This study explored motivational factors which support fanship of Major League Soccer. Further implications were discussed.

Lip-reading is the task of inferring the speaker's utterance from silent video based on learning of lip movements. It is very challenging due to the inherent ambiguities present in the lip movement such as different characters that produce the same lip appearances. Recent advances in deep learning models such as Transformer and Temporal Convolutional Network have led to improve the performance of lip-reading. However, most previous works deal with English lip-reading which has limitations in directly applying to Korean lip-reading, and moreover, there is no a large scale Korean lip-reading dataset. In this paper, we introduce the first large-scale Korean lip-reading dataset with more than 120 k utterances collected from TV broadcasts containing news, documentary and drama. We also present a preprocessing method which uniformly extracts a facial region of interest and propose a transformer-based model based on grapheme unit for sentence-level Korean lip-reading. We demonstrate that our dataset and model are appropriate for Korean lip-reading through statistics of the dataset and experimental results.

An interest in 'ordinary things' has been increased because public things become issues as the influence of mass media including mass production has been increased in the 1950s. And this phenomenon drew an art style of pop art in the world of art. Media art means that the fine arts are expressed by means of media such as TV and monitors because media has been developed in the modern society. It started emerging through the artists such as Nam June Paik, Bill Viola, and others in the 1960s. Recently, it can be easily accessible not only at the art museum but also in everyday life such as cafe, park, fashion show, performance, and etc. This study analyzed that how many different techniques of pop art were borrowed by especially Nam June Paik media art and how they influenced it. Accordingly, this study respectively analyzed expressive techniques and characteristics of both pop art and Nam June Paik's media art and then searched for their similarities based on the analysis. Both Nam June Paik's media art and pop art extended media by using various ordinary things in everyday life neglected previously as a material. Next, the characteristic of pop art shown in Nam June Paik's media art is participation with audience. While the arts in the past were high-level culture that only certain people could understand and enjoy, pop art or Nam June Paik's media art is an art trend that has led the popularity of fine arts and audience participation in order to let diverse classes enjoy without any specific knowledge.

As an exploratory research on China's animation, this study aims to enhance an understanding of the trends and characteristics of China's animation through examining its history and to forecast its future development trajectory. From its founding to recent period, China tried to maintain Communist political system through imbuing national identity to its people through management and supervision of media products under direct government's leadership in combination with ideological education. Such policy was also implemented in animation, major audience of which is children. With regard to the introduction of the policy and its influence, five historical phases could be identified as follows. During the first phase, from the founding of the Republic until the Cultural Revolution, national culture was introduced to China's animation. The second phase, which corresponds with the Cultural Revolution period, marks the decline of national culture. National culture was reemphasized during the third phase that follows the Cultural Revolution, which led to the nomination of the 'China school,' followed by the fourth phase, during which China's animation suffered the second decline due to the spread of TVs and foreign animation imports. Reintroduction of national culture on China's animation in the context of rapid industrialization process before and after 2000 characterizes the recent phase. It can be expected that although there could be some change in methods and forms, China's animation, which introduced national culture from its inception and maintained remarkable resilience following the period of decline, will continuously stress the its own national cultural identity.

The objective of this study was to understand the characteristics of Chinese cultural industry shown in the analysis of a successful IP martial arts stage play 'Seongeomg ihyeopjeon' that applied martial arts as Chinese traditional culture. The cultural industry of Chin a has modified the relevant legislation since China's reform and opening up in 1979, and the term 'intellectual property rights(IP)' was used in the Chinese laws for the first time in 2008. Thus, transcending the instrumental scope for maintaining the regime in the past, the culture was regarded as an economic profit industry and a representative industry for strengthening the soft power of traditional culture. The results of analysis on the stage play are as follows. First, the Chinese cultural industry has been developed by support policies for strengthening the soft power of Chinese-characteristic traditional culture and overseas expansion through the state-led modification of relevant legislation. Second, the Chinese cultural industry is including its unique traditional cultural factors, and the succe ssful marke ting results could be obtained only when the high awareness and many fans are secured. Third, for the inflow of audiences through the work advertising, it would be preferentially needed to analyze various opinions of fans through active SNS communications with them instead of the existing advertising such as TV, radio, and newspaper, and also to reflect the national cultural industry policies and producers' opinions.
