The purpose of this study is to analyze visual environmental elements of game space by play-event in adventure games. We extracted common six types of play-event through exploring ten representative adventure games and organized three types of space structure and four types of object as the criteria of analysis. Based on the criteria, we embodied the characteristics of visual environmental elements by performing direct playing and monitoring. As a result, we verified that the story intended and the gameplay induced by the play-event are closely related to visual environmental elements.

Active catalog is a kind of digital content that enables consumers to test the functions and features of products from their PCs as if they were using it in real life, by simulating the actions and responses of the product. This new type of interactive digital content can be used extensively to make sales personnel training manuals, sales tools, user manuals and user trouble shooting documents. With active catalogs, companies will be able to compare different designs, show actions according to different functions, and evaluate user reaction to new products without having to produce a single physical prototype or mock-up. At the same time, consumers will be able to understand and 'operate' the product and make well-informed purchase decisions. In this paper, we present a visual event-driven modeling tool, PlayMo, for creating active catalogs, analyze the advantages of using PlayMo, describe the event-driven method used by PlayMo and also introduce two enhanced characteristics of the Event Flow Chart with which the events in PlayMo are structured. Interactive digital content by using the PlayMo3D makes easy, simple and effective design for e-learning, e-catalogue, e-marketing/sales, e-prototyping, customer support, etc. Through its application-ready 3D function visualization solution, engineers and designers can rapidly turn a CAD design model into a 3D interactive virtual product, and the effective function prototyping job can be also completed within a minute.

Free-to-play business model, which first commercialized in Korea, now becomes crucial sales drivers in the game industry, but the theoretical background is not well known that most of free-to-play content business models are developed based on the guts and trial-and-errors. In this study, we verified that the price discrimination theory in economics is the backbone of the free-to-play business model, and we also derived the three boundary conditions that should be satisfied in the business model design. We reviewed the three boundary conditions of free-to-play business model using case studies of previous games, and showed how the boundary conditions should work in the actual business. Through case studies, we tried to suggest the theoretical basis of free-to-play business model design, and sales enhancing techniques in free-to-play business.

This study aimed to determine whether there is a significant difference in play properties in the case of media conversion through the combination of analog three-dimensional puzzles and immersive media in children's experience. Based on Roger Caillois' play theory and the contents of previous research, an experience was conducted on an experimental group and control group, and a questionnaire was prepared. The results of the correlation and paired t-test analysis showed that the play properties were higher and more evenly distributed in the media conversion immersive experience. This implies that an increase in children's fun during the immersive experience further increases their immersion, suggesting that the use of immersive media may have a positive effect on children who achieve holistic development through play and experience. We hope that this study will help recognize the difference in effectiveness through conversion into immersive media and will be referenced in various media studies that consider double-play properties.

In this paper, self-networking and replaceable structure in vector graphics contents are presented for wireless internet service. The wireless networks over 2G or 3G are limited in the sense of the speed and the cost. Considering these characteristics of wireless network, self-networking method and replaceable structure in downloaded contents are introduced in order to save the amount of data and provide variations for contents. During the display of contents, a certain data for the contents is downloaded from the server and it is managed appropriately for the operation of the contents. The downloaded materials are reflected to the original contents using replaceable structure. Also, the downloading and modification are independent of the play. In this implementation, the data consists of control data for control and resource data for image, sound or text. Comparing to the conventional methods which download the whole data, the amount of the transmitted data is very small since only the difference is downloaded. Also, during the play of the contents, the changes are adopted immediately. The whole functions are implemented in wireless handset and the various applications are discussed.

This study is to think a new arena of collective play culture at the university campus festival for digital generation used to be individually consuming play in cyberspace. While cyberia is virtual cultural space by providing gigantic platforms in which producers and consumers meet, this space has characterized as individuality and disembodiment, that is why recalling the collective play culture at the off-line. This article is to examine the characteristics and meaning of the recent campus festivals during the history of Korean college festivals, and to analyze proposals of play-contents applied by various theories. The 2016-7' proposals include several kind of board game and experimental theatre sublimed philosophical reflection, which shows a kind of attempt to escape from the cultural industrial logic, however they are characterized by Ilinx(drinking culture) and Alea(board game) emphasized more than Agon, and Mimicry combined with paidia rule strongly. Under the neoliberalism, college students' gloomy reality is represented emasculating of the structure of competitions in the context of an unreal world and Mimicry of experience stay in front of the limen before entering the embodiment.

Objectives: This study aimed to investigate the current status of oral health applications developed for smartphones because they can be used as a new educational medium to manage and improve oral health. Methods: This study examined 60 basic oral health applications provided by Google Play Store and Apple App Store as of May 2019 and examined delivery contents, delivery methods, application types, and other information. Results: Apple included 65.4% of oral apps in the game category whereas Android included 64.3% in the education category (p>0.05). All Apple's apps and 71.4% of Android apps were developed overseas (p<0.01). The delivery contents were 61.5% for Brushing + tooth decay in Apple, and 78.6% for others (oral care products and gum diseases) in Android (p>0.05). For the delivery method, game + video was 65.4% in Apple, and game and other methods (text, image, augmented reality) was 42.9% in Android (p>0.05). In the case of application type, play type was the most common with 88.5% in Apple, and 46.4% play type and 39.3% other type (text, appreciation, problem-solving types) in Android (p<0.01). In addition, play type was high in both education (53.8%) and game (90.0%) categories (p>0.05). The average review score was 4.30 in the education category, 4.34 in the case of brushing and care (delivery contents), 4.37 in the case of using game + video (delivery methods), and 4.57 in the case of Play + other types (application type) (p>0.05). Conclusions: The use of healthcare apps is expected to increase owing to improved lifestyles, an increase in the elderly population, cost-effectiveness, and convenience that is not affected by time and place. Effective use of oral health apps will require the participation of dental professionals in the development process to identify the exact status, expand subjects, and provide appropriate information.

Recently, the regular service of a terrestrial digital multimedia broadcasting(T-DMB) made faster distribution of T-DMB receiver. The problem of an illegal distribution is increasing owing to a large distribution of T-DMB receiver. In this paper, we propose a watermarking and encryption method on T-DMB bit-stream for a copy and Play control to prevent an illegal distribution of T-DMB contents. We implement our proposed method on a portable multimedia player (PMP) which has T-DMB receiver. The proposed method insert the encrypted information for control of copy and play after finding padding area of program map table (PMT) and program association table (PAT) from analysis of transport stream (TS) of T-DMB. In implementation result, we can control use of contents according to information of copy and play control. The proposed method can be used to content Protection software for blocking of an illegal distribution of T-DMB contents on a mobile T-DMB receivers.
