디지털 홈 시대의 도약으로 가정용 TV의 기능과 그 역할이 확대되면서 Digital TV(DTV)가 새로운 가전기기의 하나로 등장하게 되었다. DTV를 통한 디지털 데이터 방송뿐 아니라 웹 컨텐츠의 다양한 활용이 가능하게 되면서 기존의 PC 환경과는 다른 DTV 환경에 적합한 새로운 컨텐츠 표현 규격이 필요해졌다. 이에 다수의 디지털 데이터 방송 표준 단체들이 DTV를 위한 디지털 데이터 방송용 컨텐츠 표현 규격을 제시하고 있고, DTV가 등장하기 이전부터 TV와 웹의 접목 기술을 위한 W3C의 활동도 있어왔다. 또한 양방향 TV 서비스 또는 웹 TV 서비스를 제공하는 방법으로 자체적인 컨텐츠 표현 규격을 정의하고 브라우저 등의 프로그램을 통해서 시청자들에게 TV에 특화된 다양한 웹 컨텐츠를 제공하고 있다. 이에 본 논문에서는 현재까지 제시되어 온 DTV 또는 TV환경을 위한 컨텐츠 표현 규격들을 다양한 관점에서 비교 검토해보고자 한다. 또한 DTV가 가지는 특징들을 살펴봄으로써 TV와 다르고 또한 PC와도 다른 DTV만의 특성을 반영할 수 있는 컨텐츠 표현 방법을 제시하고자 한다. 이를 통해서 DTV 시장 활성화의 선두 위치에 있는 국내에서 DTV 용 컨텐츠의 표현 규격에 대한 보완 및 발전 방향을 숙고하고, 세계적으로도 앞서가는 인터넷 서비스 시장이 DTV를 통해서 안방에서 보다 효율적이고 간편한 방법으로 다양한 계층의 사용자에게로 확대될 수 있는 계기를 마련하고자 한다.

This study was conducted to analyze the moderating effect of self-expression and attitude toward help on the relation between interpersonal relationship and bullied experience among adolescents. Participants were 316 junior and highschool students in Seoul and Namyangju, Gyeonggi-do during May-June, 2014. As a result of analyses, first, the interpersonal relationship and self-expression had significant negative impact on bullied experience. Second, there was no significant correlation between attitude toward help and bullied experience. Third, self-expression had a significant moderating effect on the relationship between interpersonal relationship and bullied experience. Specifically, high self-expression weakened the negative influence of interpersonal relationship on bullied experience. Fourth, there was no significant moderating effect of attitude toward help on the relation between interpersonal relationship and bullied experience. Based on these results, we discussed the importance of self-expression for prevention of bullying among adolescents.

The esthetics of 'grotesque' and its entertaining values have many things in common with the characteristics and properties of animation as a medium of expression. The ways to express grotesque images in animation have expanded its realm of expression with the development of modern image digitalization technologies. The grotesque images that were expressed by the combination of photographs and animations and objet animations have been developing its disharmony in a more realistic manner with full 3D animation technology and realistic motions of virtual characters with motion capture. The subject matter also has become more diverse with the advance of modern scientific civilization. An example is the appearance of Cyborg(cybernetic+organism) characters and the grotesque images in the modern times mainly start to appear in animations dealing with the isolation of human beings among its characteristics. Also, the changes of the expression methods of grotesque images along with the development of visual technology development in the future will transform its methodological forms by changing its expression methods to VR forms and interactive visuals. Thus it is expected that the grotesque images and characteristics will change into a visual genre which emphasizes dehumanization.

This study examined the middle school students' psychological well-being, emotional expressiveness and peer relationships according to sex, and the relationships among them. The participants of this study were 391 second grade students at a middle schools located in Gyeonggi-do. The collected data were analyzed using a t-test, Pearson's correlation analysis and stepwise multiple regression analysis. The results were follows: First, there were significant differences in the psychological well-being, emotional expressiveness and peer relationships according to sex. Female students had higher levels in all variables than male students. Second, there were significant relationships among psychological well-being, emotional expressiveness and peer relationships. In addition, psychological well-being and positive emotional expressiveness, negative expressiveness in the sub-factor of emotional expressiveness were significant predictors of peer relationships. These findings provide suggestions regarding the plan to improve middle school students' peer relationships.

Analyzing the inner meaning and expression of philosophy by analyzing the composition, symbolic expression, and style of the film with high artistic perfection, which contains the spirit of the times, considers human beings through society and history, and raises awareness of life and the present generation. It will be a very meaningful and valuable study in film as art. The movie 'Rome' was cut into the rest of the public's mind by being tempered, hidden and omitted, and the color was black and white. Many aesthetic attempts can be found through symbolic images expressing the ironic message of maid's daily life as a race, capital, socially oppressed history. It can be seen that he expresses his own authorism visual language by drawing symbolic expressions through many contrasts and symbolic expressions through objects. The analysis of commercial films containing these artistic values is expected to help in the future production as a measure of the progress of art films and precedents of authorism expression techniques.

In this study, experimental guide materials for teachers were developed so that algorithm expression, the core of computational thinking, can be applied to experimental activities. The experimental manuals presented in text was converted into an algorithmic form with a linear, branched, and repetitive structure according to the information visualization process using flowchart symbols. As an example, an experiment guide materials was developed by applying an algorithm expression to an experiment to find out the properties of a magnet. The developed experiment guide materials is different from the existing experiment guide materials expressed only sequentially in that it has an algorithmic structure of branching and repetition in which the suitability and judgment of information are expressed, and that the experiment process is visualized and expressed. It is expected that the experimental guide materials developed in this study will help teachers to understand algorithmic thinking and to implement experiments using it.

Among many other factors associated with anger expressions and problem behaviors, the effect of temperament has not been much investigated in adolescents. Thus, the purpose of this study was to investigate the relationship between temperament and problem behaviors in adolescents, and whether dysfunctional anger expressions mediated this relation. A total of 360 students in either middle or high school participated but only data from 354 surveys were analyzed. We found that temperament was associated with dysfunctional anger expressions and problem behaviors, and the relationship between temperament and problem behaviors was mediated by dysfunctional anger expressions. Temperament adaptability was shown to be negatively related with dysfunctional anger expressions and problem behaviors, while temperament approach was shown to be positively related with anger-out expression and externalized problem behaviors. This study suggests that appropriate intervention of anger related issues in adolescents considering their temperament should is needed.

Recently realistic descriptions have been frequently used in anti-smoking campaigns. The same trend can also be seen with regard to posters as a medium of visual communication. It was intended to examine how different types of visual images in anti-smoking campaign posters produced and distributed by the WHO can improve the effectiveness of health communication. This article aims to determine how each of abstract/stylized illustrations and realistic images might affect the three key variables of the Theory of Planned Behavior, which are Attitudes toward the Behavior, Subjective Norms and Perceived Behavioral Control, in relation to quitting smoking. Results showed that realistic images are different in improving the attitudes toward the behavior and subjective norms. However, there are no significant difference between abstract/stylized illustrations and realistic images in Perceived Behavioral Control. The findings of this study suggest that the above-mentioned types of visual information achieve different levels of effectiveness in health communication. It is desirable that more effort be devoted to the interdisciplinary study across the areas of visual design and social psychology, for example, with a view to developing better health communication strategies.

In this study, we focus on the classifying and representing data in the elementary mathematics curriculum for 1st and 2nd grades which have been rarely addressed in the previous studies. We analyze the significance of classifying and representing sata in terms of statistical problem solving and variability as the core of statistical literacy. As a result, the classifying and representing data are important for students to recognize the variability which is ubiquitous in the data and to construct distribution of data, respectively. They are reflected in the 2015 revised mathematics curriculum as the statistical literacy for addressing data. We suggest some implications to teach the classifying and representing data as the practice of statistical literacy education in their statistics classes for 1st and 2nd grades.

Internet becomes more and more popular, and most companies and institutes use web services for e-business and many other purposes. With the explosion of Internet, the attack of internet worm has grown. Simulation is one of the most widely used method to study internet worms. But, it is quite challenging to simulate very large-scale worm attacks because of various reasons. By this reason, we often use the modeling network simulation technique. But, it also has problem that it difficult to apply each worm attacks to simulation. In this paper, we propose worm attack representation and mapping methods for apply worm attack to simulation. The proposed method assist to achieve the simulation efficiency. And we can express each worm attacks more detail. Consequently, the simulation of worm attacks has the time-efficiency and the minuteness.
