Recently, a lot of smart devices such as smart phones have been spread. The research on smart education based on the devices are being actively investigated. A typical example of them is EPub3.0 proposed by the IDPF. Even if the educational content has supported multimedia such as image, video, text to speech and etc, it does not support a 3D virtual content yet. So a virtual reality-based education has not been achieved. In this paper, we propose an educational content system in which a virtual education simulation is possible through smart devices. To do it, the proposed system consists of an authoring tool creating 3D virtual educational content, and a viewer visualizing the content. The experimental results showed possibility of virtual experience education.

This study attempts to introduce and develop nature experience program utilizing the instructional mixed reality and examines its effects on creativity and young children in order to overcome the limitations that can be found when young children explore and observe nature. In addition, the purpose of this study is to investigate the change aspects of creativity and nature-friendly ability of young children when experiencing nature with the further activities using the instructional mixed reality. To verify the effect of the instructional mixed reality developed through this process, this study selected 30 young children who are 5 years old in H child care center located in Seoul. As a research tool, creative test of characteristics for children (K-CTC) produced and standardized by Chung Kyung-won (2003) was used to test creativity. As data analysis methods, SPSS 17.0, T-test, MANOVA test, and repeated measure ANOVA were conducted.

Since the conventional methods of physical therapy may decrease the motivation of a patient for rehabilitation due to repetitive, monotonous movement, a new physical therapy system inducing a motivation from the patient is needed. The present study is intended to develop a physical therapy serious game for enhancement of dynamic balance control. The balance control therapy game was developed by the following steps: (1) survey of existing balance control therapy systems, (2) analysis of balance control literature, (3) ideation and architecture planning of the balance control therapy game, and (4) implementation of the balance control therapy game. The proposed physical therapy serious game can provide better usability, satisfaction, clinical effectiveness for balance control than the conventional methods.

In recent, modern people has been suffering from their hair loss. According to the definition, hair loss refers to the status in which hairs on certain regions are lost, due to multiple causes albeit they are supposed to be present under normal conditions. Compared to the normal hair growth cycle, numbers of hair loss outnumber the newly growing hairs and there is excessive amount of hairs in the resting phase, thereby resulting the reduction of total numbers of hairs. In the present study therefore, we designed and developed the scalp management system to pursue more efficient management of hair loss. In the suggested system, scalp types were classified as follow: Plain Scalp, Dry Scalp, Oily Scalp, Compound Scalp, Sensitive Scalp, Seborrhea Scalp, Pressure alopecia Scalp, Tinea capitis Scalp, Aging Scalp, Inflame Scalp, Psoriasis Scalp, Steroid side effect Scalp, alopecia scalp and so on. It was designed that each individual can perform the scalp imaging analysis using the system so that relevant experts review diagnosis history of existing databases and diagnose various statuses of scalps. Utilizing the system herein, we are looking forward to improving competitiveness of relevant industries.

In this study, a digilog program is suggested for the integration of analog and digital media. As analog sensibility is giving way to digital, analog is now being regarded as old and outdated, and various emotional advantages of analog are being disregarded. A program constituting eight lessons was conducted for third-grade students through Chochungdo. In this program, analog expressions were interpreted in a digital environment and the students experienced game characteristics in artistic media. The educational effects were as follows. First, an expanded audio-visual effect was displayed, using Flash on a 2D plane, based on analog emotional expression. Second, students experienced game characteristics through interaction using the MaKey MaKey program, and an immersive digital environment within a media device.

The location-based game(LBG) is a major game which is using temporal-spatial model as a game space like a real world in mobile environment. A gamer have to fight with game-enemies who have low level power for their victory. Then conventional researches have studied finding lower level game objects using skyline query in spatial game. However, since the researches which are using traditional skyline (TS) just query in one quadrant, the surrounding objects of a gamer can not be queried. This paper proposed a safe-route search scheme that a gamer searches the surrounding objects and safe-routes to level up in his/her power using Global Skyline query. In simulation, we evaluate two safe-route that a game object’s game-level and distance from gamer. The result shows that a gamer has high game-level after game-level-oriented evaluation. That is, the proposed scheme could be an advanced scheme to level up a gamer’s power in location-based game.

Benjamin introduced the concept of the “aura”and discussed its absence in film and photography. Benjamin posited that the loss of aura changes artistic values. This brought about a paradigm shift in the entire mode of existence of humanity. After Benjamin, various opinions followed regarding the concept of aura, namely, aura collapse, aura transformation, aura-media, and returned aura. This study discusses the idea of the “aura”in games as a digital medium. From the three characteristics of games,i.e., presence, interactivity, and multi-sensory interface, it is evident that digital aura exists in games in the form of immersion. Analogue aura has lapsed because of technical shortcomings, but digital aura makes perfect simulacra that create a hyper-real world. The qualities of immersion, interactivity, and a multi-sensory interface provide a world of illusion, and provide the visual, auditory, and tactile experience of aura without any space between the user and the object.

In cloud and game servers, SSDs are used as cache on large capacity disk-based storage. In that configuration, the SSD can be exploited as write-back or write-through cache. Though the write-back cache can improve write performance significantly, data can be lost when the SSD fails. On the contrary, performance improvement is limited in the write-through cache though it has high reliability. By the way, reliability can be improved by applying RAID technique to SSD cache while exploiting write-back for better performance. In this paper, we analyse the reliability and the performance of hybrid storage using SSD cache over disk-based primary storage. In particular, we mathematically analyse reliability and also measure performance of real storage systems with various SSD cache configurations.

Recently, the computer software has become an increasingly important share in the overall industry and many countries have been adapted an early SW education as their mandatory curriculum in school for children. Most of the prior SW education curriculums had been focused on how to learn a programming language to make a SW in a computer, but current SW education goal has been moved onto training the computational thinking to solve various problems with the computer, effectively. The paper exploits a game design activity as a good and fun tool to training such computational thinking for children. The proposed game design activity consists of a series of systematic curriculums to design a creative game in offline for the children who do not have any prior-knowledge of game. Participants first understand game elements such game title, synopsis, rules, game-play, which are indispensable to make a game. Then they try to understand what the fun is in the game and discuss with how to make such fun in the game. Finally, they have proposed a creative game design which is motivated by playing board-style games and iPad-games. With our assessment of the proposed activity, our game activity derives let the participants to computational thinking while creating the synopsis and game rules to define the game. It also revealed increased interest and understanding of computer software. We expect that the proposed game design activity could be an alternative to train computational thinking and a more holistic program to have increased interest and understanding of computer software for children.

The popularity of online games highlights the need for research approaches that can increase our scientific understanding of online game play experience. This paper proposes a model for examining and evaluating the ways by which factors of game motivate players and shape psychological processes. Previously, Nick Yee has done one of the most extensive and influential empirical research on motivations for play in online games. His research provides the foundation to understand what motivates people to play games and how we can improve our designs based on those findings. His factor analysis revealed ten motivational sub-components that grouped into three overarching components of achievement, social, and immersion. However, there are a handful of empirical results that were unique and did not clearly fit into Yee's motivational components, such as "making a difference", "the search for self", "the search for youth", and "the nurturance motivation", as Yee acknowledged in his paper. Therefore we developed a motivational theory of "reality integration" to encompass the cases that could not be explained by Yee's theory. While his theory was implicity focused on "escapism" (escape from reality), we found that dual and integrated perspectives of "reality integration" and "escapism" of online games are very important in understanding players' behavior and improving game design. The future goal of this research is to develop a motivational design framework for educational games or serious games.

The N-Screen contents is a kind of emerging technologies to make a new user-experience by integrating multiple devices like smart TVs, personal computers, and smartphones. In the paper, we characterize game design issues of N-Screen based game with smart TV and smartphone and describe the game design issues of 「Beaver Rising」as its case study.「Beaver Rising」is the N-Screen game which developed by our team ans its' game play is similar with a classic game, called「Snake」but it can be played on a smart TV screen while players can control their own beaver characters with their smartphones. We first give a survey of N-Screen games to characterize their properties in the paper. Then, we describe the game play, game design architecture, and user experience of the game,「Beaver Rising」as its case study. Finally, we propose three new properties to make an effective N-screen game with a smart TV and smartphons. The paper will contribute to provide am effective game design guideline when we make a N-screen based game with a smart TV and smartphones.

The aim of this study is to verify the effects of user experiences such as present, flow and arousal between game play under 3D virtual environment(VE) and general video game play. For this purpose, Oculus Rift play test experimental treatment methodology was adapted for analysis. As a result, for the present hypothesis between the VE game and general video game, cognitive and present hypotheses were all adopted except for emotional presence, and there was no difference in arousal effect. And, VE game had significant differences in emotional presence, flow concentration effect, flow merging action & awareness and arousal effect compared with general video game. As the study verified that VE game had higher effect in presence effect, sense of realism and user experience of players than general video games through experimental studies, it contributes to elaborate 3D virtual environment game interface design and user experience study.

For increase the game speed, game systems apply a multi-threading. The popularization of multi-core system accelerates multi-threading also. Multi-threading brings high performance, but this is not ease to apply the game logic. Because many multi-core system share the memory, if two or more threads access the same memory region, they can be conflicted. Multi-threading uses Lock method to prevent the conflict, but Lock method reduces the performance. For increase the performance, programmer can use Lock-Free method. In this case, we found strange phenomenon that Lock-Free queue operates incorrectly, and this phenomenon has been accelerated by number of threads. In this study, we analyzed the input output of the Lock-Free Queue in multi-core system.

The game intended for treatment directly is not yet much in domestic and even though it is used for child psychotherapy, the direct game therapy has not been used yet. But the possibility of the game therapy is likely to increase in the future due to emerging the field of virtual reality therapy, recreational therapy. In this study it is proposed the rhythm game using the balance ball connected the wired/wireless PC, it is the reason why the functional game may help the upper limb rehabilitation if you are using it continuously without a place, time, and cost constraints.

Recently, education game contents with advanced mobile and Web technology have been widely researched. However, considering of interaction involved for children, it is necessary user friendly interfaces and interesting interactions. In addition, it is important to design to encourage the user’s learning motivation as a way to the effect of educational game contents. Therefore, in this study, we designed and implemented the educational game contents system using inter-working between KINECT camera, PC, and android platform based humanoid robot. The designed system consisted of KINECT system for capturing hand gestures, game contents system for playing games, and android humanoid robot system for interacting with users. This system can lead to interests and willingness of users through handy interaction such as hand gestures and interesting quiz game contents. To improve effectiveness and userability, we plant to advance designed educational game contents system that can be operated on a smart TV system including a built-in camera as a further study.

Recently, the game industry is rapidly growing with the distribution of high-speed internet network. With the growth of game business, the game developers and distributors are making efforts to find more various game materials that lead to success. Therefore, the game developers began to apply successful novels or movies for games and, as a result, they were able to get high added values with the minimum investment costs. In this study, the Game contents is reviewed based on Suzanne Collins's trilogy 'The Hunger Games' published in 2008. If 'The Hunger Games', the novel of thrilling adventures and suspense harmonized with philosophy, is reprocessed as game contents considering media environment, the values of the novel will be more diversified and newly enjoyed by people. As the research method, the actantial model of Greimas and the five conflict types of Linda Seger were used for a case study and the Game contents of the novel. The study using the novels as source materials was conducted to be helpful for game development and its possibility was suggested through the study result.

When a game was developed, it is impossible to predict the success of the game. Most game developers made a game play test stage in game development process. It is important factor that gamer have good emotion playing the game. There are many ways of gamer's emotion test such questionnaire suvey, EEG test and etc.. but their tests are hard to quantify the results. Gamer's emotion are evolveing according to playing the game. Gamer's emotions are one of important criteria that is used for choosing a game by gamers. Nevertheless, the emotion detection is not considered for play test, because of the difficulty. The emotions of each gamers are different because of their own skills, experiences, preferences, etc. In recent years, the emotion detection technology is evolved, but it is not enough to guarantee the accuracy. In this paper, we propose a hybrid emotion classification system by EEG(Electroencephalogram) test, questionnaire suvey and eyetracking.

The personality of individuals are different form each other and they have a different feature. So when they playing games, it would be common for them to choose the character that mach for their personality. When MMORPG game compares to the other genre of games, it has many characters and users can choose the character that fits their personality to playing a game. However, some MMORPG game was not doing well in the game markets because the form of common MMORPG have no differentiation with each others. In this research, will use the egogram to drew the character element of individuals and with that output use the AHP to show you the result of important analysis about the character element of individuals’s favor game characters. This research can use as base of developing a new games or updating a new contents, regulating balance between the characters.
