한 · 중 게임기업의 투자 성향이 경영성과에 미치는 영향
전호진 ( Hojin Jeon ) 한국비교경제학회 2017 비교경제연구 Vol.24 No.1
본 연구에서는 한국과 중국 게임기업을 대상으로 투자특성이 경영성과에 미치는 영향을 살펴보았다. 투자와 관련하여서는 투자규모와 경영성과 간에는 대체로 한국과 중국 모두에서 유의한 양(+)의 관계를 도출하였으며 투자의 증가율이 높을수록 중국 게임업체의 ROE가 유의적으로 증가하는 모습을 보였다. 연구개발 투자와 경영성과 간에는 대체로 음(-)의 유의한 결과를 도출하였다. 연구의 결과물로 사료되는 무형자산과 관련하여서는 유의한 결과를 많이 도출할 수는 없었으나 중국 게임기업의 경우 무형자산이 증가할수록 경영성과에는 긍정적인 영향을 미쳤다. 인력규모와 경영성과 간에는 대체로 양(+)의 관계를 보였으며 인력규모가 확대 될수록 한국은 음(-)의 경영성과를 중국은 양(+)의 경영성과를 도출하였다. 안정성 지표와 관련하여서는 대체로 부채비율이 높을수록 한국과 중국 모두에서 경영성과에는 부정적인 영향을 미치는 결과를 보였다. The study examined the impact of the investment characteristic in Korea and China game firms on their business performance. the positive relationship could be derived between scale of investment and business performance. in relation to investment. both Korea and China game firms. in terms of R&D performance , the significant negative relationship could be found with business performance.

This paper introduces PongBot, a quadruped robot developed for preparation in the Dronebot Challenge held in Jangseonggun, Jeollanam-Do, South Korea in November 2020. The Dronebot Challenge, hosted by the Army Headquarters, is a competition to demonstrate that drones and robots can be useful for military purposes. In 2020, this competition consisted of a total of 8 events and we participated in the ‘Traveling on rough terrain’ event, which consisted of various terrains, such as, slopes, unpaved roads, and streams. PongBot is a quadruped robot that uses an electric motor and can walk for more than an hour on various terrains. Also, according to the rules of the competition, the robot had a system which could be remotely controlled from a ground control station. In addition, by applying the SLAM algorithm, the robot operator received information about its surrounding environment, thereby deriving records to facilitate the operation. The performance of this robot system and SLAM algorithm was verified through this competition.
