In recent years, machine learning algorithms are continuously being used and expanded in various fields, such as facial recognition, signal processing, personal authentication, and stock prediction. In particular, various algorithms, such as deep learning, reinforcement learning, and Q-learning, are continuously being improved. Among these algorithms, the expansion of deep learning is rapidly changing. Nevertheless, machine learning algorithms have not yet been applied in several fields, such as personal authentication technology. This technology is an essential tool in the digital information era, walking recognition technology as promising biometrics, and technology for solving state-space problems. Therefore, algorithm technologies of deep learning, reinforcement learning, and Q-learning, which are typical machine learning algorithms in various fields, such as agricultural technology, personal authentication, wireless network, game, biometric recognition, and image recognition, are being improved and expanded in this paper.

The flight information visualization of the aircraft is the system which is widely used to the threat against low altitude tasks and terrain altitude. But, it is difficult to implement the system because of restrictions that GPS data and huge geographic information should be stored. In this paper, it proposes economic DMM (Digital Moving Map) system for flight information visualization from open-source-base. First, the flight information is transferred from X-Plane through UDP and then demonstrated on the DMM system. In the proposed DMM system, flight information is visualized on the map information downloaded from an ArcGIS Map server using the mapping data between the present altitude of the aircraft and the terrain altitude. The result of this paper could be used an economic tool in the field of flight information visualization and the game algorithm research.

A graphic simulator can be a useful tool for planning gaits or dynamic behaviors to a walking pet robot. Microsoft describes robotics developer studio (MSRDS) as an end-to-end robotics development platform including simulation engine based on dynamics. In this paper, we propose a pet robot simulator (PRS), based on MSRDS, which supports interactively controlled two walking robots connected over network. To be pet robot simulator, modeling a commercial pet robot is performed and gait planning is also implemented. By using concurrency and coordination runtime (CCR) and decentralized software services (DSS) of MSRDS software platform, we connect two robots which are displayed together but controlled separately over network. The two walking pet robots can be simulated interactively by joysticks. It seems to be an internet game for pet robots.

The purpose of the study was to analyze consumers' perceptions of gamification. Based on the analyzed data, we would like to provide data by systematically organizing the concept, game elements, and mechanisms of gamification. Recently, gamification can be easily found around medical care, corporate marketing, and education. This study collected keywords from social media portal sites Naver, Daum, and Google from 2018 to 2023 using TEXTOM, a social media analysis tool. In this study, data were analyzed using text mining, semantic network analysis, and CONCOR analysis methods. Based on the collected data, we looked at the relevance and clusters related to gamification. The clusters were divided into a total of four clusters: 'Awareness of Gamification', 'Gamification Program', 'Future Technology of Gamification', and 'Use of Gamification'. Through social media analysis, we want to investigate and identify consumers' perceptions of gamification use, and check market and consumer perceptions to make up for the shortcomings. Through this, we intend to develop a plan to utilize gamification.

The informatization of Korea is accompanied by the great growth of new strategic export industry, as of mobile phone or semiconductor LCD. Speaking to the situation of mobile phone, Motorola swept over the American domestic market in the beginning of 1990s, digital mobile communication as CDMA developed swiftly in Korea. In 1996, the first year's CDMA users of Samsung were merely one million, nevertheless, the world's sales in the first half of this year is up to 92 million. In this p aper I design 3D application based on J2ME and implement a freely removable 3D object which happened in a 3D scen e by receiving the keyboard response of mobile device with WTK (Wireless ToolKit) simulator. It contains benefits of improvement of relative speed and high-level functionality such as scene graph, keyframe animation, etc.

Unity is a powerful game engine that can be used to create 2D or 3D content. The current study focuses on the use of Unity for 3D computer animations, covering the strengths, basic concepts and tools for creating and integrating 3D animations in Unity, including the use of keyframe animation, animation controllers, and blend trees. Also covering advanced topics such as skeletal animation, procedural animation and their applications in games, simulations, and other interactive media. Case studies that showcase the potential of Unity for 3D animation will be analyzed and discussed taking in the quality of visuals and the receptance by the public in general.

현재 컴퓨터교육에서 알고리즘 교육의 중요성은 강조되고 있지만 주어진 문제를 알고리즘으로 표현하고 표현된 알고리즘을 해석하는 방법에는 비교적 연구가 미약하였다. 본 연구에서는 알고리즘의 표현 도구 중 순서도에 대해 초등학교 저학년 대상으로 놀이 활동 기반 학습 방법을 개발하고 실제 수업에 적용하여 학습 가능성을 진단하여 보았다. 학습 놀이는 순차형 놀이, 선택형 놀이, 반복형 놀이와 퍼즐 맞추기 게임으로 4가지이며 퍼즐 맞추기 게임은 학습 놀이 내용을 순서도 카드를 활용하여 실제 순서도로 재구성하는 게임이다. 순서도 학습 후 성취도 평가에서는 학습 놀이 기반으로 수업을 진행한 집단이 ICT기반으로 학습한 집단보다 상대적으로 평균은 약 7.5% 높게 나타났으며 두 집단 모두 학습 후 평균이 10점 만점에 9점 이상을 보였다. 이는 순서도 교육이 초등학교 저학년도 학습 가능하며 특히 놀이 활동을 통한 교육이 효과적이라는 것을 보여준 것이다.
