  • 온라인 게임은 가상 재화를 현금화할 수 있게 되면서 여러 가지 부정 행위가 발생하고 있다. 그 중 대표적인 것이 사용자 대신에 게임 플레이를 해주는 게임 봇(game bot)이다. 이러한 게임 봇은 사용자는 물론 게임회사에 큰 해를 입히고 있다. 본 연구에서는 게임 봇을 탐지하는 기존의 연구 중 사용자의 행동 로그를 분석하는, 데이터 분석 기반의 연구를 조사하였다. 관련 연구를 사용자의 행위를 중심으로 구분하였고, 향후 연구가 나아갈 방향에 대해 첨언하였다.

  • 온라인게임은 부정로그인 및 게임봇 (Game BOT) 탐지 등 서비스에 악영향을 주는 이상징후를 조기에 탐지해야 하는 서비스 분야이다 보니, 데이터기반 보안 (Data-Driven Security)이 상당히 오랜 기간 자생적으로 구축이 되어왔다. 온라인 게임은 초당 동시접속이 800만~1천만에 육박하는 게임도 시장에 빈번히 존재하기 때문에, 게임유저들의 로그데이터를 빅데이터 기술을 접목한 데이터 분석이 필수적이다. 본고에서는 온라인게임 분야에 존재하는 다양한 위협요소 중 하나인 게임봇 및 작업장 탐지에 적용된 데이터기반 보안 기술들에 대해 조사하고 향후 온라인게임분야에서의 데이터기반 보안의 연구 방향을 제시해 보고자 한다.

  • I study a solution concept which preserves the nice Nash equilibrium properties of two-person zero-sum games, and define a locally competitive equilibrium which is characterized by a saddle point with respect to the coordinates of strategies. I show that a locally competitive equilibrium shares the properties of uniqueness of equilibrium payoffs, interchangeablity of equilibrium strategies and convexity of the equilibrium set.

  • Environmental taxes tend to compound the welfare cost of pre-existing tax distortions, the tax-interaction effect, however they also raise government revenues, tax revenue-recycling effect. By incorporating these two opposite tax effects, this paper examines a second- best environmental taxation for a polluting monopolist with distortionary taxes. The analysis suggests that the complications posed by pre-existing tax distortions as well as market structure can be key considerations in designing environmental taxes. In the tax setting game between regulator and regulated firm, we also derive the equilibrium tax rate and examine its relationship with distortionary taxes.

  • 온라인게임은 출시 후 2~3개월 안에 인기를 얻지 못하면 시장에서 퇴출되는 게 일반적이다. 만성적인 자금 압박 등으로 인해 결국 서버를 내렸던 무협 온라인게임, ‘디오온라인’역시 그렇게 사라지는 듯 싶었다. 그런데 이변이 일어났다. 2년만에 서비스를 재개한 이 게임은 지난해 12월 동시접속자수 6,000명을 기록하더니 올해에는 최고 1만4,000명을 넘어서는 등‘후폭풍’이라는 표현이 어울릴 정도로 화려하게 재기했다. 뒤늦게 인기몰이에 성공한 디오온라인을 살펴봤다.

  • This study is based on the theory of R.Caillois about element of play which is motivated to infant for studying Hangul. The ultimate goal of play has to be accompanied by pleasure. And learning means permanent changes from experiences for the individual's. Play and learning, these two elements are united to the genre of serious game since the GBL (game based learning) was lead. Most importantly, in order to achieve their own Hangul learning is the fun. Coupled with fun and learning has an important issue for flow because concentration is low in infants than adults. In this case study is to know about fun factor has been applied effectively to Hangul serious mobile game. 20 Infant Hangul mobile serious games of Google Android mobile game section were selected as a case study based on more than 10,000 downloads and user's review rate by April 22, 2014. After that is currently available on the market can play a variety of cases of infant learning Hangul from previous research of R.Caillois offers four categories of play. R.Caillois of Agon, Mimicry, Alea, Ilinx have unique characteristics in comparison with its functional characteristics Hangul four are present any role in Hangul serious mobile games. As a result of the cases selected and the rules of the game will include a maximum of two of the most common types of Agon. Each attribute of the play, rather than one single factor is applied to four kinds of game play performance when properties are distributed to experience together gave the best flow. As a result of this study will be a based research for infants Hangul serious mobile game reflects the properties of the elements of a fun game that you want to combine learning.

  • This study suggests a methodology for automatically extracting placing information from 2D reinforced concrete details drawings and generating a 3D reinforcement placing model to develop a mobile augmented reality for bar placing work. To make it easier for users to acquire placing information, it is suggested that users takes pictures of structural drawings using a camera built into a mobile device and extract placing information using vision recognition and the OCR(Optical Character Registration) tool. In addition, an augmented reality app is implemented using the game engine to allow users to automatically generate 3D reinforcement placing model and review the 3D models by superimposing them with real images. Details are described for application to the proposed methodology using the previously developed programming tools, and the results of implementing reinforcement augmented reality models for typical members at construction sites are reviewed. It is expected that the methodology presented as a result of application can be used for learning bar placing work or construction review.

  • Background: Digital therapeutics are software medical devices that provide evidence-based treatments to prevent, manage, and treat disease. Digital therapies have recently been shown to be effective in motivating children with cerebral palsy as a tool in neuropsychological therapy. Digital therapies improve postural control, balance and gait in children with cerebral palsy. Therefore, this study aims to investigate the effects of digital therapies on balance and gait in children with cerebral palsy and to provide guidelines for prescribing digital therapies for children with cerebral palsy. Design: A Systematic Review Methods: This study searched for English-language articles published in medical journals from January 2000 to July 2023 using PubMed and MEDLINE based on the year of initiation of the digital therapy. The search terms used in the study were 'digital technology' OR 'digital therapeutic' OR 'mobile application' OR 'mobile health' OR 'virtual reality' OR 'game' AND 'cerebral palsy', 'balance' 'gait' as the main keywords. The final article was assigned an evidence level and a Physiotherapy Evidence Database (PEDro) score to assess the quality of clinical trials studies. Results: The digital therapies applied to improve balance and gait in children with cerebral palsy are game-based virtual reality training and the Nintendo Wii Fit program. Both digital therapy interventions had a significant effect on improving balance in children with cerebral palsy, and virtual reality training significantly improved balance and gait. However, there were no significant improvements in balance and gait within two weeks of treatment, regardless of the type of digital intervention. Conclusion: The study suggests that this data will be important in building the evidence base for the effectiveness of digital therapies on balance and gait in children with cerebral palsy and in advancing clinical protocols.

  • Online customer reviews (i.e., electronic word-of-mouth) has gained considerable interest over the past years. However, a knowledge gap exists in explaining the mechanisms among the factors that determine the product sales in online retailing environment. To fill the gap, this study adopts a principal-agent perspective to investigate the effect of customer reviews and customer incentives on product sales in online retail stores. Two customer review factors (i.e., average review ratings and the number of reviews) and two customer incentive factors (i.e., price discounts and special shipping offers) are used to predict product sales in regression analysis. The sales ranking data collected from the video game titles at Amazon.com are used to analyze the direct effects of the four factors and the interaction effects between customer review and customer incentive factors to product sales. Result reveals that most relationships exist as hypothesized. The findings support both the direct and interaction effects of customer reviews and incentive factors on product sales. Based on the findings, discussions are provided with regard to the academic and practical contributions.

  • This paper deals with methods for determining the reasonable royalty rates in the valuation of patents. To calculate the reliable reasonable royalty rate of a patent, we review pros and cons of the 25% rule royalty calculating method and the recent trend of this method. We also review the game theory of Nash Bargaining equation and review the Investment of Rate of Return Method according to the financial analysis. Next, we refer to the reasonable royalty damage cases among the recent patent infringement cases in USA and analyze the corresponding patents. We extract the patent indicators from the patent bibliographic information. Finally, we obtain a regression model for calculating a reasonable royalty rate using the patent indicators and the reasonable royalty rates in the recent patent infringement cases.
