Recently, many public institutions have been conducting promotional activities using digital platforms. Communication methods using digital platforms have a very important meaning in that they can create new values that did not exist before by connecting and sharing information with various users. To this end, we tried to analyze YouTube videos of five government ministries and examine them. As a result of YouTube analysis by government ministries, most of them were mainly used as channels for policy promotion, and many were used as channels for new information. Although the message is delivered through the production of various contents, it was possible to look at cases where the target as a channel for communication was not clear and the purpose was unclear. In order to communicate with the people, it should be used as a channel for communication through content suitable for clear target setting and purpose.

This study analyzed the factors that viewers consider when watching anime on Over The Top(OTT) service platforms and the characteristics of each type of preference, which are the components of anime preference. To this end, the survey data of 240 animation major students were used for analysis, and the conclusions drawn through frequency analysis and cross-tabulation of IBM SPSS Statistics 27 are as follows. Netflix is the OTT service platform that viewers use the most, and TV series are the most preferred for animation works. In addition, it was found that Netflix OTT original animation works were preferred over other platforms, and long-form animation preferred Disney+. Among the characteristics of each type of animation preference, it was found that the factors considered when watching animation in terms of narrative value, aesthetic value, and entertainment value respectively value the structure, screen production, and immersion of the storyline. It is hoped that this study will be used as useful data for producing animation contents with the OTT service platform.

For an advanced intelligent service, the need of HRI technology has recently been increasing and the technology has been also improved. However, HRI components have been evaluated under stable and controlled laboratory environments and there are no evaluation results of performance in real environments. Therefore, robot service providers and users have not been getting sufficient information on the level of current HRI technology. In this paper, we provide the evaluation results of the performance of the HRI components on the robot platforms providing actual services in pilot service sites. For the evaluation, we select face detection component, speaker gender classification component and sound localization component as representative HRI components closing to the commercialization. The goal of this paper is to provide valuable information and reference performance on appling the HRI components to real robot environments.

ROS is based on a graph architecture where processing takes place in nodes. Nodes communicate together by passing messages through topics based on the publish/subscribe model. On the other hand, OPRoS components know each other and are tightly-coupled via port connections, and different coupling schemes make the interoperation between two platforms difficult. This paper describes an extension of OPRoS framework to support the interoperation with the ROS topic.

Energy is a direct restriction to the working life of an underwater mooring platform (UMP). In this paper, a vertical axis water turbine (VAWT) is designed to supply energy for UMPs. The VAWT has several controlled blades, which can be opened or closed by inside plunger pumps. Two-dimensional transient numerical studies are presented to determine the operating performance and power output of the turbine under low ocean current velocity. A standard k-${\varepsilon}$ turbulence model is used to perform the transient simulations. The influence of structural parameters, including foil section profile, foil chord length and rotor diameter, on the turbine performance are investigated over a range of tip-speed-ratios (TSRs). It was found that turbine with three unit length NACA0015 foils generated a maximum averaged coefficient of power, 0.1, at TSR = 2.

As flash technology is a widely used in Web pages, it tends to load a S/W flash player in mobile phones and PDAs to play flash contents on diverse H/W platforms currently. In this paper, we design and implement a linux-based standalone flash player which can be used in various fields like animation, game and advertizing. We also implement an web-based manager which user can effectively manage flash players anywhere.

With the development of AI (artificial intelligence), animation digital publishing has been integrated with intellectualization. This paper adopts the theory of the global value chain, and analyzes the basic structure of the animation publishing value chain. Then focuses on the analysis of digital technology and artificial intelligence technology to play an active role in the topic selection and content customization of animation digital publishing products, optimization of publishing platforms, and user experience of publishing products. Finally, it proposes the use of artificial intelligence data analysis and deep learning technology. The purpose of this paper is to realize the upgrading of animation digital publishing, product upgrading, industrial chain upgrading, and identify some promotion methods for the value chain, such as copyright protection.

Recently, LNOI photonics technology has attracted attention as a photonics platform capable of integrating ultra-high-speed, low power consumption, and high nonlinearity optical devices, as it is possible to manufacture LiNbO₃ optical waveguides with ultra-low optical loss and a radius of curvature of several tens of micrometers. Here, we will briefly compare various photonics platforms, such as Si, InP, SiN, and LNOI, describe the current research trends of LNOI photonics, and discuss the direction of photonics technology at the conclusion.

The advent of social media has revolutionized the speed of communication between millions of people around the world in various cultures and disciplines. Social media is the best platform for exchanging opinions and ideas, interacting with other users of similar interests and sharing different types of media and files. With the phenomenal increase in the use of social media platforms, the need to pay attention to protection and security from attacks and misuse has also increased. The present study conducts a comprehensive survey of the latest and most important research studies published from 2018-20 on security and privacy on social media and types of threats and attacks that affect the users. We have also reviewed the recent challenges that affect security features in social media. Furthermore, this research pursuit also presents effective and feasible solutions that address these threats and attacks and cites recommendations to increase security and privacy for the users of social media.
