최근에 모바일 게임을 즐기는 이용자들이 증가하고 있다. 우리나라 뿐만 아니라 전 세계적으로 모바일 게임의 인기가 식을 줄 모르고 있는 가운데 블루오션이라 불리는 중국시장을 겨냥해서 게임이 개발되고 있다. 게임의 장르는 서바이벌(생존)게임인데, pc게임시장에서는 서바이벌게임이 상위권에 많은 반면 모바일시장에서는 서바이벌 장르의 게임의 비중이 적다. 뿐만 아니라 모바일시장에는 카피캣 게임이 대다수를 차지하고 있다. 본 논문에서는 틈새시장 공략하기 위해서 서바이벌(생존)게임을 기획하고 새롭고 참신한 독자적인 모바일게임을 개발에 대한 연구를 한다. 유비쿼터스 컴퓨팅 환경에서 다양한 접속 채널과 서비스 플랫폼에 대응하는 게임의 개발도 요구 되고 있는 상황에서 본 연구에서 개발된 게임은 좋은 사례가 될 것이다.

Recently the telemedicine platform firms which have been temporarily permitted since COVID-19 outbreak have increasingly provided online prescription drugs delivery, causing concerns among incumbent providers of medicine, some of whom began to take aggressive actions again them. In this study, using game theoretic market entry - deterrence model, we show that although the incumbent medicine provider can effectively deter entry by the telemedicine platform firms by its preemptive action, accommodation could be a optimal action when telemedicine platform firms already have penetrated the market with their being permitted to do business due to the COVID-19. However, for the incumbent to cooperate for the successful change in the retail market for medicines, policies like placing a ceiling on the maximum number of taking prescriptions by the pharmacists a day in the telemedince platform network, providing favorable exposure of community pharmacists on the telemedicine platform user interface, and allowing community pharmacies to participate as shareholders of the telemedicine platform firms in its initial public opening of capital, are suggested.

Procurement of development funds is a very difficult process in the Korean game industry where competition is fierce. Recently, crowdfunding has been used as a convenient platform to attract potential investors to secure the development cost of the game. This study explored the factors influencing the success of crowdfunding for game development projects. We collected data on 229 game development projects in Tumblebuck, a reward-based crowdfunding site in Korea. According to the results of the logistic regression model, the factors that have a positive effect on the success of funding are the average compensation amount relative to the target amount, the number of SNS shares, the number of updates, and the originality of the proposed game. Video playback time has been found to have a negative impact. Based on the results of this study, it is expected that planning a game development project considering the variables affecting the success of crowdfunding will help financing.

We propose a brain-machine interface(BMI) based human-robot interaction(HRI) platform which operates machines by interfacing intentions by capturing brain waves. Platform consists of capture, processing/mapping, and action parts. A noninvasive brain wave sensor, PC, and robot-avatar/LED/motor are selected as capture, processing/mapping, and action part(s), respectively. Various investigations to ensure the relations between intentions and brainwave sensing have been explored. Case studies-an interactive game, on-off controls of LED(s), and motor control(s) are presented to show the design and implementation process of new BMI based HRI platform.
