Recently, new content for e-leisure, including e-sports and e-games, has become necessary. To meet this requirement, e-leisure mobile AR studies which track human are underway. The tracking performance at long distances is important because e-leisure mobile AR is used in outdoor environments. However, conventional mobile AR applications such as SNOW and Snapchat have the disadvantage of low tracking performance at long distances. Therefore, we propose an e-leisure mobile AR in outdoor environments. The proposed e-leisure mobile AR can estimate the position of the head in outdoor environments at long distances by using color markers and the human body ratio, and then augment a virtual object at the estimated position. The performance of the proposed e-leisure mobile AR was evaluated by measuring the tracking performance and processing time.

As games have been used throughout the advertisement design in diverse ways, the paradigm of the internet advertising has also been changed. At the same time, there has been a growing tendency among companies to maximize the purpose of advertising by using game-like internet banner advertising, which provides internet-users with the information of the advertisements by exposing specific information, brands, characters, or image. In spite of the quantitative expansion of the game-like internet banner ads, according to a survey with regard to their click-through rate(CTR), the result indicates the CTR is less than 0.5%. Therefore, this study aims to examine what types of displaying elements of the game-like banner ads gaining in popularity can leave the users with a strong impression, and also to explore what types of displaying elements need to be highlighted for the users' active and aggressive access to internet banner advertisements. Currently advertised game-like banner ads on the internet web sites in different fields are selected. Then, they are analyzed by using seven categories. The findings are expected to lay out systematic and practical guidelines for the future production of game-like banner ads.

MMORPG online game business has emerged as the most lucrative entertainment industry, with over 10 million gamers in South Korea. It appears that in this extremely attractive and growing services segment, academics, as well as practitioners, would benefit from investigating the relationships among the players' attachment or affection, game contents-related and social interaction-related construct. We assume that game contents-related construct consists of storytelling, game-play method, contents-diversity and the sense of identification, and that social interaction-related construct includes information-sharing, gamers' empowerment and the word-of-mouth. Based on data collected from online questionnaire survey, the validity of the research model has been tested. The results show that contents-related construct influences the players' attachment, and that social interaction-related construct has no direct impact on the attachment. But social interaction-related construct has been shown to influence contents-related construct, implying the indirect impact on the players' attachment.

Illegal game players' hacking and propagation of malignant code in online game exposes privacy of online game customers. So, online game companies have to support the standardized systems and operations of customers' privacies. Since online game companies implement authentication of information protection, which focuses on assets or physical, systemic security, they need a more professional system that is related to protection of individual privacy. We analyzed the individual information protection system, which includes ISO27001, ISMS of KISA, GMITS, ePrivacy, online game privacy protection guide, and BS10012. Using the suggested systems, we proposed the systemic tools that measure the level of individual information protection, which includes process and check items of each phase.

This research is the study of raindrop rendering. In case of rendering for raindrop in existing games, it is used on sprites images or roughly raindrops images using texture rendering. These methods are similar to the shape and size of all rendered raindrop. That's why players are limitations to provide a sense of reality. To overcome this limitation, this paper proposes a method for generating raindrop considering surface tension and contac angle, the amount of water, implements the raindrop using Unity3D engine. To demonstrate the usefulness of this paper, this paper shows the generated raindrop in accordance with the change in the area and pulling force in surface tension formula. This paper can help to provide the actuality in game in case of rendering the raindrop.

A smart TV is able to show terrestrial broadcasting and also can be used as a computer -VOD, games, image communications, application utilities and so on. In order to carry out Smart TV business, it has to contains contents, platforms, network terminal unit. If ill-equipped with any of these aboves, it must cooperate with other licensee. Therefore, Smart TV business is necessary to cooperate with each business agent. In this paper, we will look into domestic/foreign country Smart TV market, policy, vitalization strategy, and suggest the application of big data analysis methodology for Smart TV vitalization method - 1) hardware infrastructure building based on cloud computing 2) Network upgradability acceptable traffic increase 3) Technical development cooperation between each licensee 4) Variable Smart TV contents supply 5) Cooperation with party interested individuals in using UX/UI for N-Screen, network traffic estimation may increase, customized supply smart contents for consumer in real time.

Interest in Augmented Reality (AR) game $Pok{\acute{e}}mon$ GO is getting heightened. However, based on its characteristic, various direct and indirect problems are highlighted, thus increasing concerns. Although the game is not formally released domestically, there are limits in national game classification to apply on such outdoor Augmented Reality game. This paper will examine the problematic cases regarding Pokemon GO and analyze internal and external game classification system to discuss safe gaming measures for domestic users. In result of examining cases, need for adding 'physical danger' in current game classification system for user's safety was shown. As the government's game regulation is being eased, appearance of a variety of games using Augmented Reality technology in near future is predicable. Therefore it is important to prepare improvement of game classification system as a pre-safety measure, and it is expected to bring positive effect on game usage and industrial growth through safe game usage.

The objective of this research is to empirically analyze the impact of contents update or patch service in online game, being provided after delivery to correct faults and to improve performance of the game. Regression analysis is applied to the data set, where the weekly increase rate of playing times is dependant variable, and the time(week) and two types of contents updates are introduced as independent variables. Statistical results show that the time(week) negatively influences the weekly increase rate of playing times. But the impact of new contents generation and contents adjustment on the weekly increase rate of playing times is not statistically significant, implying that once online game is published, contents update has no significant impact on the playing times. Implications for game designs are provided as a conclusion.

The Haenyeo of Jeju exists as a unique human resource only in Korea and Japan in the world. Especially, the anti-Japan opposition movement of the Haenyeo of Jeju, which had started to get the right to live on their own in 1931, had developed as the national liberation movement by struggling against a colonial of Japan and the official regulation association that was a plundering organization of Japan. Accordingly, there is making an effort to register Jeju's women divers as The National Treasure in UNESCO's Memory of the world. In this research, we are going to make stuff like a digital storytelling, characters, animation movies, games, and hompage to let our children understand and succeed the spirit and culture of the Haenyeo. We'll also use these contents for the education. We examine ways to recreate the culture resources related to the Haenyeo who gradually vanishes.
