Importance and necessity is enlarged due to globalization. So, English education is diverse and recently applies AR(Augmented Reality) technology to offer immersion and interest. Contents in this paper are Mobile AR contents for training infant English cognition. Our system displays teaching aid objects into 3D models, lets infants listen to English conversation and teaches them everyday English like a play. Considering infants that like games, this system adds an English game about each object of teach aids. To attract infants and parents interest persistingly, We give them immersion and interest by suggesting a different event at each step.

In this paper, we propose a development methodology of interactive stereoscopic image display system. In our case, we consider a multiple touch recognition technique as the interaction method. That's because we want to guarantee multiple user access and interaction to the content without any restriction. In this case, however, some restrictions are occurred on account of the distance between display and participants. For this reason, this paper propose an invisible interaction surfaces which are generated in the air. This surface is utilized as interaction medium instead of the display wall. We also present an effective way to generate and edit interactive stereoscopic images based on Game Engine.

In this paper, the assessment items were selected for water by drought, water quality by drought, and thermal diseases by heat wave. We described the selection background for these assessment items. and then we weighted the selected vulnerability assessment items. The vulnerability assessment procedures also describe the calculation methods applied in phases and the actual cases. The vulnerability assessment database was analyzed and a climate change vulnerability assessment system for heat waves and droughts using these vulnerability assessment procedures was designed.

In the fifth generation (5G) mobile networks, the interactive mobile game users have increased tremendously, which induces correlated information sources (CIS). One of the promising 5G technologies is non-orthogonal multiple access (NOMA). In NOMA, the users share the channel resources, so that CIS affect each user's bit-error rate (BER) performance, which is not the case for orthogonal multiple access (OMA). In this paper, we derive the optimal receiver for NOMA with CIS, and then investigate the impact of CIS on each user's BER performance.

The flying-disc game has started since 1940. It has been spreading rapidly in Korea since 2007, mainly in elementary schools. Additionally, as sports science has been developed, research on flying discs has been continued to build a monitoring system for technological improvement and efficiency. In this paper, we acquire information on the user's flying-disc using 9-axis motion sensor and GPS. Then we propose a method for wireless transmission using Bluetooth 5.0. Specifically, the HW platform was designed and implemented not only to monitor a real-time data but also to compare and analyze rotational speed, flight trajectory, and a count of disc rotation through post-processing.

Sports video is a very critical information resource. High-precision extraction of effective segments in sports video can better assist coaches in analyzing the player's actions in the video, and enable users to more intuitively appreciate the player's hitting action. Aiming at the shortcomings of the current sports video clip extraction results, such as strong subjectivity, large workload and low efficiency, a classification method of sports video clips based on MobileNetV3 is proposed to save user time. Experiments evaluate the effectiveness of effective segment extraction. Among the extracted segments, the effective proportion is 97.0%, indicating that the effective segment extraction results are good, and it can lay the foundation for the construction of the subsequent badminton action metadata video dataset.

Sentiment analysis, a branch of natural language processing that classifies and identifies subjective opinions and emotions in text documents as positive or negative, can be used for various promotions and services through customer preference analysis. To this end, recent research has been conducted utilizing various techniques in machine learning and deep learning. In this study, we propose an optimal language model by comparing the accuracy of sentiment analysis for movie, product, and game reviews using existing RNN-based models and recent Transformer-based language models. In our experiments, LMKorBERT and GPT3 showed relatively good accuracy among the models pre-trained on the Korean corpus.

Piano is one of the most beloved instruments in the world and is used a lot for children to learn music because it is simple to play. As a result, various products for children, such as toy pianos, were released. However, there is a lack of piano skills for music education, such as how to play the piano or read the score. To solve this problem, in this paper, we propose a game-style educational piano using Arduino. It is expected to capture fun and education at a low price by scoring points by displaying the score on the LCD screen and pressing the keyboard according to the timing of playing the note.

This paper is a study of the changing nature of software for virtual Cyborg self and the virtual body that occur in the game from a philosophical point of view. Looking broadly, the cyborg concept refers to the combination of man and machine. Specifically, there is a hardware cyborg organism to combine human and restoration of machine In addition, there is software cyborg by electronic the human brain of converting a virtual body. Virtual games are cases software-Cyborg applied. In the game , There seems to have characteristics of virtual body and ego that different from general cyborg meaning. To analyze the features, I applied the concept of software-cyborg of Hans morabek and the multiple selves in cyberspace properties of Kim Sun-Hee. generally, software cyborg cloning the brain type tended to invalidate the body due to the nature of the virtual world. But If you look at third-person's view and the game character that made from real actors, it is pursuing the realism of photographic images and it stressed the need for a virtual body in order to maintain the psychological identity of the player. And, The game player crosses the eight characters to choose while completing the mission. This is a big role in the reality ego leads to the desired final ending with the selection and experience to be experienced as self-replication to multiple. These cyber multi-ego looks for an active and positive features compared to the multi-ego in the real world and highlights the advantages of the software cyborg. Game The characteristics of the final result varies depending on the selection of the player. The life and death of a friend is determined by the relationship between the characters friendship. In this case, the virtual self is empirically through trial and error, moral, and try to select the desired setting the standard for intuitive and self own choice. Also It can be fused to the knowledge of multiple selves as one step is formed by a high spiritual introspection. This process is a positive interpretation of the world and their own forms of mental reflection through self-overcoming human, Nietzsche is said that the process is Wibeomenswi.
