The Internet of Things (IoT) is a new concept associated with the future Internet, and it has recently become a popular concept to build a dynamic, global network infrastructure. However, the deployment of IoT creates difficulties in satisfying different Quality of Service (QoS) requirements and achieving rapid service composition and deployment. In this paper, we propose a new QoS control scheme for IoT systems. The Markov game model is applied in our proposed scheme to effectively allocate IoT resources while maximizing system performance. The results of our study are validated by running a simulation to prove that the proposed scheme can promptly evaluate current IoT situations and select the best action. Thus, our scheme approximates the optimum system performance.

The basic idea of IoT(Internet of Things) is interconnection and cooperation with a variety of things in real life such as Radio-Frequency Identification(RFID) tags, sensors, mobile phone, etc, through internet. IoT technologies which applied to these fields consist of sensor network technology and middleware, application. Currently, IoT technology is applied to various fields such as health care, home care, automotive, transportation, construction, agriculture, environment, food, and etc, based on its technologies. This paper focuses on discussion of the game planning method in IoT environment. In order to achieve this purpose, first, introduce the IoT technologies. Second, propose a game design elements and considerations in IoT environments. It can help for game developers by using IoT technologies.

Recently Internet of things(IoT) industry has grown, Giant company of the world, have developed a variety of equipment using this. Several things are to be able to enjoy the game of devices have been developed game that play with the device has been released. This paper aims to derive the necessary element for the game development around IoT equipment. In this study, we investigated several cases using IoT device that have been released and have been developed abroad, literature related to game development reviewed. As a result, majority case using in game field, it appeared by using virtual reality that supported the 3D screen using a head-mounted display, in addition, have been released motion-based game.

최근 사물인터넷 기술은 4차 산업혁명을 이끌 차세대 성장기술로 많은 분야에서 기술도입과 융합을 시도하고 있다. 장난감 시장 역시 사물인터넷 기술 도입으로 많은 변화가 일어나고 있다. 특히, 단순한 조작 위주의 장난감을 스마트 기기, 센서 등과 연동하여 원격제어를 하고, 부가 정보를 축적하여 활용함으로써 사장되었던 많은 장난감들이 새로운 놀이도구로 재생산되고 있다. 본 논문에서는 대표적인 놀이기구였던 팽이를 새롭게 사물인터넷 기반 스마트 팽이로 제작하기 위한 방안을 제시한다. 스마트 팽이는 초소형 아두이노 보드를 장착하고 스마트폰과 통신이 가능하도록 하여 회전 및 충돌 정보를 스마트폰으로 전송하도록 한다. 또한, 스마트 팽이에 솔레노이드를 이용한 점핑 모듈을 추가하고 스마트폰에서 점프 명령을 내릴 수 있도록 함으로써 게임 참여자의 직접 제어가 가능한 스마트 팽이 대전 게임을 구현할 수 있도록 한다.

The world is changing rapidly as the Internet spreads and various smart devices appear. High-performance PCs and high-speed communication networks are rapidly spreading in every home, and all kinds of the internet sites are emerging. In particular, the high education enthusiasm of Korean parents adds to this, and the ratio of the internet users among teenagers is exploding every day. In the case of adolescents, most of them use the Internet for online games, indicating that online games are the main cause of the internet addiction. This study was conducted using a questionnaire for male and female high school students using the Internet, and demographic and sociological characteristics were used only as basic data. In this study, as much as parents, students and teachers think, the results of the internet addiction type analysis according to academic achievement in humanities high school students are to be investigated to determine whether internet use has an effect on academic achievement.

Brain-Machine Interfaces(BMI) are interfaces that control machines by decoding brainwaves, which are electrical signals generated from neural activities. Although BMIs can be applied in various fields, their widespread usage is hindered by the low portability of the hardware required for brainwave measurement and decoding. To address this issue, previous research proposed a brain-machine interface system based on the Internet of Things (IoT) using cloud computing. In this study, we developed and tested an application that uses brainwaves to control the Pong game, demonstrating the real-time usability of the system. The results showed that users of the proposed BMI achieved scores comparable to optimal control artificial intelligence in real-time Pong game matches. Thus, this research suggests that IoT-based brain-machine interfaces can be utilized in a variety of real-time applications in everyday life.

Focusing on the differences in perceptions of color education fields between game majors and game designers. As a result, game major college students were surveyed to have a low recognition rate for the color field, the other group were not. for resolve the gap in perception, it's suggested need to re-educate systematic color education of game major college students and color experience of game designers in terms of securing expertise. it's expected to be presenting the direction of fostering game designers with color sense that contributes for the competitiveness of the game industry.
