This research analyzed the relationship and the interaction effect between information understandability and information acquisition level in accordance with government's official message presentation types, in other words, press release in text form, infographic that visualize a large amount of information, and webtoon that helps to understand convoluted information in interesting ways. As a result of research, it was confirmed that there exist both main effect and interaction effect in official message types presented by government and information understandability according to the environmental awareness. In addition, the main effect per each variable was confirmed between official message types presented by government and information understandability according to the environmental awareness; however, the interaction effect per each variable was not confirmed. Such research result is meaningful in that it provides the government with basic data in obtaining the effectiveness and usefulness of the information dependent of the official message types presented by government to the information consumer facing the era of government 3.0.

We will analyze how color is used creatively in essential work, Red Deser, directed by Michelangelo Antoioni, one of the most unique film director in film history. in Red Desert, Antonioni especially tried to focus on the use of color to develop the narrative. Therefore, through the analysis of the Red Desert, this paper will endeavor to support the perspective that the role of color is not only a mere backdrop but has the primary funtion of storytelling in this film.

In this study, I would like to conduct a study on the design of chat UX between fandom and idol. The 1:多 form of message exposure method between idols and fandom was studied and the optimal exposure form and speed were tested. Based on the results of the experiment, 30 sentences were selected per second among various options, and based on this, the results were applied to the actual Universe platform to facilitate communication between idols and fans.

무선 센서네트워크에서 지상시설물 관리를 위하여 대상 시설물에 대한 이벤트 발생 메시지 및 상황보고 메시지에 의한 데이터 수집 및 분석에 따르는 기존의 방식에 의해서는 시설물 상황 파악의 한계를 가지고 있다. 따라서 본 논문에서는 기존의 무선 센서네트워크에 적용되는 게이트웨이 기술에 영상 카메라를 이용한 영상제어 게이트웨이를 제안한다. 영상제어 게이트웨이를 적용함으로서 이벤트가 발생한 해당 센서노드에 대한 상황을 영상으로 인지하고 운용자 및 관리자의 시각적인 영상 정보 확인으로 관리대상 시설물의 상황 파악에 대한 정확도 및 신뢰도를 증대시킬 수 있다.

메시지전달 병렬프로그램에서는 메시지들의 경합으로 인해서 의도하지 않은 다결정적인 수행결과가 초래되므로, 메시지들의 경합을 탐지하는 것은 중요하다. 이전 연구에서 경합을 탐지하는 다양한 기법들을 제안하였으나, 각 탐지기법의 기능을 검증할 수 있는 방법은 없다. 이는 기존 경합 탐지기법과 새롭게 개발되는 경합 탐지기법의 기능을 검증하기 어렵게 한다. 본 연구는 기존의 경합 탐지기법들을 구현하여 각 기법들의 탐지결과를 비교함으로써 그 기능을 검증할 수 있게 하는 시험도구를 제안한다. 본 시험도구의 사용자는 기존의 경합 탐지기법과 새로운 탐지기법을 선택하여 적용할 수 있고, 탐지된 결과에 대한 시각화 정보의 비교를 통해서 탐지기법들의 기능을 검증할 수 있다. 그러므로 본 도구는 새로운 경합 탐지기법의 개발을 위한 효과적인 기능시험을 가능하게 한다.

This paper presents a time synchronization algorithm based on PLL for application to telemetry systems and implement FPGA logic. The large aircraft of the telemetry system acquires status information through each distributed acquisition devices and analyzes the flight status in real time. For this reason, time synchronization between systems is important to improve precision. This paper presents a PLL based time synchronization algorithm that is less complex than other time synchronization methods and takes less time to process data because there is minimized message transmission for synchronization. The validity of proposed algorithm is proved by simulation of Python. And the VHDL logic was implemented in FPGA to check the time synchronization performance.

The purpose of this study is to primarily explore the characteristics of 'irony' and focus on the process of visualizing it. 'Irony' is one of the rhetorics used to describe the context or situational aspects of writing. This 'Dépaysement' that appears in art history corresponds to 'ironic' rhetoric in writing. 'Dépaysement' is a combination of techniques, which conveys a message through de-familiarizing rhetoric. With the images conflicting with each other in logic on the same canvas. 'Dépaysement' and 'ironic' rhetoric have commonalities in that they produce a situation with opposite or contradictory images and obscure the images and the situation by distorting them into being different from what has usually been known. In conclusion, Ironic Characteristics and Visual technique elements of dépaysement are identical, this study attempts to understand the visual language by analyzing 'the visual irony' that appears in artworks.

Time synchronization in underwater environment is challenging due to high propagation delay and mobility of sensor nodes. Previous researches do not consider practical issues affecting on the accuracy of time synchronization such as high-channel access delay and relative position between sensor nodes. Also, those protocols using bidirectional message exchange shorten the network lifetime and decrease the network throughput because numerous transmission, reception and unnecessary overhearing can be occurred. Therefore, in our research, we suggest enhanced time synchronization based on features of underwater environment. It controls the instant of transmission by exploiting the feature of an oceanic movement and node deployment. Moreover, the protocol uses more accurate time information by removing channel access delay from the timestamp. The proposed scheme is also practical on the underwater sensor network requiring low-power consumption because the scheme conducts time-synchronization with smaller transmission and reception compared with previous works. Finally, simulation results show that the proposed protocol deceases time error by 2.5ms and 0.56ms compared with TSHL and MU-Sync respectively, reducing energy consumption by 68.4%.

Data visualization has become a useful tool to effectively communicate information and is widely used not only by experts but also at a general level. However, it is dangerous that it is as efficient as it is to transmit false information. All data visualizations have hidden intent with powerful messages by editor. Building a system that grasps these intentions helps to understand the thoughts of groups and individuals. Most of the existing research focuses on effective data visualization methods and methods of expression. The more various visualization methods, the more likely the data will be distorted. In this paper, we present an analysis of deceptive data visualization in a goal-oriented environment. Based on the vulnerability of human cognitive processing, we classify the attack types and identify what tricks occur in the context of data visualization. This study suggests the first step in studying the case of aggressive visualization and opens the way for further research.

Formation of optical meaning shown in the picture book screen is the original expression method in that it makes you understand properties or characteristics of subjects more easily and faster adding another images to them, exaggerating or reducing them as well as shows the phenomenon that you try to deliver. In this study, I first prepared the framework of classification on metaphorical expression methods of the picture books' illustration through theoretical study on the optical metaphorical characteristics and expression forms to analyze how the metaphorical expression methods shown in the picture books for children works optically and psychologically to them. Also, I divided the expression form into 2 types to derive optical psychological perceptional response of children through the empirical survey and analyzed linguistic psychological response of children by type utilizing it as the survey materials of in-depth interviews. Finally, I think that the result of this study will help screen production based on personality and creativity of illustrators and, in addition, it will be utilized in studies and tests of the effective expression methods for students who learn illustration.
