This study empirically examines the effects of regulation on online gaming. Going beyond ad hoc heuristic approaches on individual behavior, we investigate the effects of regulation on dynamic changes of games or service providers. In particular, we propose three theoretical perspectives: social influence to investigate the regulation effect, the role of prior experience to determine the difference in the regulation effect size through users' prior experience, and network externalities to discover the difference in the regulation effect size according to the number of users on an online gaming platform. We use the vector autoregression methodology to model patterns of the co-movement of online games and to forecast game usage. We find that online gamers are heterogeneous. Therefore, policy makers should make suitable regulations for each heterogeneous group to effectively avoid generating gaming addicts without interrupting the economic growth of the online gaming industry.

Group communications are becoming popular in Internet applications such as video conferences, on-line chatting programs, games, and gambling. Secure and efficient group communication is needed for message integration, confidentiality, and system usability. However, the conventional group key agreement protocols are too much focused on minimizing the computational overhead by concentrating on generating the common group key efficiently for secure communication. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. After achieving the secure group communication, the secure group communication should generate the group key efficiently and distribute it to group members securely, so the balance of security and system usage must be considered at the same time. Therefore, this research proposes the software architecture model of a secure and efficient group communication that will be imbedded into networking applications.

Group communication is becoming increasingly popular in Internet applications such as videoconferences, online chatting programs, games, and gambling. For secure communications, the integrity of messages, member authentication, and confidentiality must be provided among group members. To maintain message integrity, all group members use the Group Key (GK) for encrypting and decrypting messages while providing enough security to protect against passive attacks. Tree-based Group Diffie-Hellman (TGDH) is an efficient group key agreement protocol to generate the GK. TGDH assumes all members have an equal computing power. One of the characteristics of distributed computing and grid environments is heterogeneity; the member can be at a workstation, a laptop or even a mobile computer. Member reordering in the TDGH protocol could potentially lead to an improved protocol; such reordering should capture the heterogeneity of the network as well as latency. This research investigates dynamic reordering mechanisms to consider not only the overhead involved but also the scalability of the proposed protocol.

The casinos and gaming sector consists of all forms of betting, including commercial, state-run, and charitable operations. The casinos segment comprises gambling in casinos, and includes gaming machine gambling where this occurs on casino premises. The gaming segment covers all other forms of gambling, including national and other lotteries, racing and sports betting, bingo, pachinko, and gaming machines where these are not located on casino premises. All values are stated in terms of gross gaming win. This is the total amount waged by customers minus the total amount paid out to customers as winnings, but before the payment of any applicable taxes, disbursements to charitable or other causes by games established for those purposes, or other expenses. The South American casinos & gaming sector posted strong growth in 2009 and this growth is expected to accelerate during the forecast period. The South American casinos & gaming sector generated total revenues of $9.6 billion in 2009, representing a compound annual growth rate(CAGR) of 15% for the period spanning 2005-2009. In comparison, the Argentinian and Chilian sectors grew with CAGRs of 17% and 21.9% respectively, over the same period, to reach respective values of $2.2 billion and $93.7 million in 2009. The other gaming segment was the sector's most lucrative in 2009, generating total revenues of $7.1billion, equivalent to 74.1% of the sector's overall value. The casino segment contributed revenues of $2.5billion in 2009, equating to 25.9% of the sector's aggregate revenues. The performance of the sector is forecast to accelerate, with an anticipated CAGR of 20.4% for the five year period 2009-2014, which is expected to drive the sector to a value of $24.3 billion by the end of 2014. Comparatively, the Argentinian and Chilian sectors will grow with CAGRs of 10.2% and 7.3% respectively, over the same period, to reach respective values of $3.6 billion and $133.6 million in 2014.

Arcade game up until early 2000 had been highly influential and profitable industry that occupied most of the market share for the Korean domestic game industry. However, extensive and yet tightened restrictions were imposed to the industry in 2006 due to the problems of speculative games such as winning rate manipulation, serious addictiveness, and etc. This resulted in damaging healthy arcade game business and eventually caused it seemingly impossible to comeback up until now. This study is to address the current arcade game industry in Korea along with the best practices in other countries to come up with propositions for the comeback of domestic arcade game industry and improvement of competitiveness. Ultimately it is to develop diversification and flexibility and to induce new business opportunities in the domestic arcade game industry by proposing the ways to convert the bad perception and introduction of functional games.

After being enforced web board game enforcement ordinance, the majority manufacturer of sales that had been operating a web board game was greatly reduced. This restriction is true and that it had a significant impact in preventing exchange and gambling resistance, abnormal use has occurred to still bypass. Therefore, in this study, you can either leave a note of the 'Web Board' sunset enforcement ordinance, and how the debate any changes are necessary and alternative dimension approach, especially we try to study an unusual user patterns that utilize the game system of responsibility as an alternative.

This study examines the regulatory issues and introduction problems of TV-betting data broadcasts in Korea by in-depth interview with a panel group. TV-betting data broadcast services of card games and horse racing games are widely in use in Europe and other parts of the world. In order to carry out the study, a demo program of TV-betting data broadcast in the OCAP(OpenCableTM Application Platform Specification) system environment, which is the data broadcasting standard for digital cable broadcasts in Korea was exposed to the panel group and then they were interviewed after watching and using the program. The results could be summarized as below. First of all, while TV-betting data broadcasts have many elements of entertainment, the respondents thought that it would be difficult to introduce TV-betting in data broadcasts as in overseas countries largely due to social factors. In addition, in order to introduce TV-betting data broadcasts, they suggested that excessive speculativeness must be suppressed through a series of regulatory system devices, such as by guaranteeing credibility of the media based on safe security systems for transactions, scheduling programs with effective time constraints to prevent the games from running too frequently, limiting the betting values, and by prohibiting access to games through set-top boxes of other data broadcast subscribers. The general consensus was that TV-betting could be considered for gradual introduction within the governmental laws and regulations that would minimize its ill effects. Therefore, the government should formulate long-term regulations and policies for data broadcasts. Once the groundwork is laid for safe introduction of TV-betting on data broadcasts within the boundary of laws and regulations, interactive TV games are expected to be introduced in Korea not only for added functionality of entertainment but also for far-ranging development of data broadcast and new media industries.

This study is devoted to investigating participation motivations of billiard players who join games through open-ended questionnaires, and identify the difference of participation motivations in the game according to age and experience. Thus, 696 original data on participation motivations was obtained from 267 billiard players in Gyeonggi-do based on open-ended questionnaires. Results from inductive analysis are as follows. First, their participation motivations included 10 general sectors such as interests, objective achievement motive, competition, interpersonal relationship, mental health, job, gambling, sport competence, suggestion by others, and university admission. Second, enjoyment showed the highest percents among participation motivations according to participants' age. Third, interest showed the highest percents among participation motivations in less than five years of their experiences. Objective achievement motive was the highest portion for more than five years. These outcomes will be used as a basic data to understand the relationship of billiard players who participate in the game and further create better billiard game culture.

Currently many people are concerned about 'Amusement With Prize(AWP)', together with the starting of Game Rating and Administration Committee (hereafter 'GRAC'). The mature-rated arcade games reproduced in reel game like the sea story in addition to main game and sub-game, causing social confusion in 2006, are waited for the reviewing of 'GRAC'. Although the game is reproduced in poker style as game system, in reel method as game graphic like 'AWP', the Supreme Court's decision is considered as a poker game May 23, 2013 in the past. Moreover, the Supreme Court said that it is not illegal because they decide that game users do not make a great loss in their possessions, without money change. The research tries to find the direction of the reviewing the mature-rated arcade game for guarantee of objectivity and reliability.
