The article reveals the essence of cyber socialization influencing the process of education and development. The general and potential possibilities of cyber socialization in the process of using the cyberspace of the Internet environment are presented. The sudden transition to distance learning in the spring of 2020 put the pedagogical community in the face of problems related to the content, organizational and methodological basis of the educational process. During the training in distance mode, a rich experience was gained in the use of information and communication technologies. The article discusses the techniques and methods of teaching using the capabilities of information and communication and digital technologies.

With the advent of digital age, we've come to have an affinity with multimedia, in our daily lives, which has the most visual images. Everyday, more than 90 percent of people watch television, and most of them spend their time watching television and use internet for their leisure time activity. Multimedia change and diversify rapidly and have powerful potential. However, it is true that there is a considerable limit in the use of and application for their function. In this study, I've aimed at supporting the potential of therapeutic function which visual images have as the most powerful brain-stimulating-media. In order to accomplish the purpose of this study, I've placed chroma therapy in the element of video production. Thus, I've produced functional videos which shall be the backbone of video therapy. For EEG and psychology test, 1 chose 25 employees as sample group, and testified the potential of it.

Specially, the character in the kids animation is the fundamental visual element, and also has the high value which is to connect to various related businesses. The main purpose of this study is the analysis for character's appearance by the basic plane figure, and it has studied on the authority of recognition capability which is to catch the simple shape rapidly and clearly rather than complex shape. For this study, I established the standard of analysis and then applied that to the characters which were selected in broadcasting domestic kids animation on EBS. Through this procedure, I analyzed character's appearance with the distribution chart. As the result, the circular and oval shapes are the most frequently used shapes for character's appearance. Finally, I expect the result of this study could be one of the design index for the character creation in practical environment.

In recent years, the number of love stories in Japanese TV series are decreasing. Comparing this with Korean popular TV series in Japan, it was found that Korean TV series have the following differences. In the Japanese series, the main characters were mostly from common origin. The conflicts within each relationship stage illustrated the conflicts between characters and their surroundings, as well as the conflicts which commonly arise in real life, that with the self. Confessions of love in the Japanese series used simpler expressions. Some couples did not even say "I love you". Further, when love was threatened, rarely was deep attachment shown. There were even cases where the main characters did not end up as a couple. On the other hand, there often existed a class difference between the male and female main characters in the Korean series and conflicts mostly arose from differences of environment, illness, love rivals, and etc. Every couple verbally confessed their love and they used more passionate expressions of love than in the Japanese series, and when love was threatened no man backed down and each showed his deep attachment. Finally, there were happy endings for everyone even after the many complications.

Bell Laboratory introduced the sound and visual system for the first time in 1927. Since then, the development of telecommunication technology made it possible for people located far away to communicate each other watching through the TV screen. Over the period different types of telelecturing systems have prospered in line with the development of telecommunication technology. Therefore, it is quite natural that telelecturing/conferending system attracts the attention of many people as a new way of educating people located in a long distance. In the industrial sector, telelecturing systems already come into wide use to save time and training and travelling expense. In this study, I examine the concept and characteristics of telelecturing/conferencing system and introduce different types telelecturing system developed in parallel with the development of communication technology. Then, I analyze how those merits of the telelecturing system can be applied to educational purpose. Finally, I propose and design ideal telelectuirng/conference facilities consisting of telelecturing rooms, bilateral movie system, seats, ceilings, color, TV screen, lighting, acoustics, humidities and temperature control, security system, projection system to maximize the educational purpose and effectiveness.

The purpose of this paper is to introduce some new class of rings that are closely related to the classes of sharp domains, pseudo-Dededkind domains, TV domains and finite character domains. A ring R is called a ${\phi}$-sharp ring if whenever for nonnil ideals I, A, B of R with $I{\supseteq}AB$, then I = A'B' for nonnil ideals A', B' of R where $A^{\prime}{\supseteq}A$ and $B^{\prime}{\supseteq}B$. We proof that a ${\phi}$-Dedekind ring is a ${\phi}$-sharp ring and we get some properties that by them a ${\phi}$-sharp ring is a ${\phi}$-Dedekind ring.

In this paper, we describe a software implementation of a digital TV stream analyzer that can be used for analyzing and verifying digital TV bitstreams on personal computes. It accepts as input MPEG-2 transport streams (TS's) already stored on hard disks and doesn't require any special hardware. After classifying TS packets into program specific information(PSI) TS section auido, video, program clock reference (PCR) private data and null packets, it displays their contents through a graphic user interface along with the syntax elements of the TS header. Also it displays the decoded I frame nearest in time axis the TS packet currently shown This feature helps pin pointing the specific location of problematic parts in bitstreams. The bitsteam analyzer provides the compliance test of MPEG-2 Systems standard and the data injection functionality with which one can easily insert additional data to existing MPEG-2 bitstreams. Using the resulting system one can produce at low test streams for interactive broadcasting and data broadcasting for laboratory use.

The article reports findings on: (1) development of emotion assessment scale in evaluating the Television(TV) picture quality; and (2) how psychological and physical factors relate to TV picture quality. A total of 152 adjectives that specifically describe emotional reactions were first selected from a Korean dictionary of adjectives, followed by ratings on their suitability for the evaluation of TV picture quality. The final selection of 19 adjective, based on the reported rating scores greater than 4.1, were used on 126 college students who were asked to perform similarity ratings on the adjectives. Based on factor analyses (i.e., principal component analysis with oblique rotation) on the similarity of scores, the following adjectives were selectively chosen for the development of the new emotion assessment scale: 'neat-messy', 'refreshing-gloomy', 'clean-dirty', 'comfortable-tense', 'smooth-rough', 'bright-dark', 'gorgeous-plain', 'diverse-monotonous', 'satisfying', 'natural', and 'sensuous'. These adjectives composed into two distinct constructs, 'cleanness or smart' factor and 'gorgeousness' factor, which demonstrated sensitivity to changes in brightness, contrast, color, and tint in the TV picture quality, except for changes in sharpness.
