There is a common misbelief that female gamers prefers simple cute easy games so that they are incompetent if higher skill level is required or disqualified to be a winning party member in MMORPG. This pink game theories are the results of video game analysis done in US and Europe way before online games and mobile games become popular thus. there are many evidences that such misconceptions do not hold anymore. However, researches on gender game culture and gender preferences have not been seriously conducted since 2007 in Korea. Thus, in this paper, we surveyed 88 male and 151 female gamers from their late teens to 30s and found a gap between behavior and perception due to serious gender stereotypes. Gender differences are still found in several areas, but the degree of differences were weakened or in different direction from 2007. The game design to attract female gamers should understand such gender gaming culture and gender difference.

Games can be divided into different genres such as action, adventure, role playing, simulation and etc based on the types of the play provided to a player. And each genre has various kinds of balancing system. Fighting games are classified as one of the action genres. They seem to have a simple structure but there is a variety of complex balancing factors. Because there are quite a number of the fighting games that were developed in a relatively short period, it is possible to identify diverse balancing systems in the fighting games from unstable ones in the early stage to the recent ones in a stable condition. The balancing system allows players to use all the contents offered in the game by eliminating the imbalance created among the various components. It helps players maintain their interest during the procedure. Furthermore, it gives the justification, increases the efficiency of controlling, and develops the empathy in the process. Therefore, the balancing system plays a crucial role in the games when it comes to getting an evaluation and building popularity, which can determine its lifespan. In this study, we researched on the possibilities of expanding an application to the other genres by understanding the established balancing model developed from the case study of the fighting games.

Obviating user churn is a prominent strategy to capitalize on online games, eluding the initial investments required for the development of another. Extant literature has examined factors that may induce user churn, mainly from perspectives of motives to play and game as a virtual society. However, such works largely dismiss the service aspects of online games. Dissatisfaction of user needs constitutes a crucial aspect for user churn, especially with online services where users expect a continuous improvement in service quality via software updates. Hence, we examine the relationship between a game's quality management and its user base. With text mining and survival analysis, we identify complaint factors that act as key predictors of user churn. Additionally, we find that enjoyment-related factors are greater threats to user base than usability-related ones. Furthermore, subsequent quasi-experiment shows that improvements in the complaint factors (i.e., via game patches) curb churn and foster user retention. Our results shed light on the responsive role of developers in retaining the user base of online games. Moreover, we provide practical insights for game operators, i.e., to identify and prioritize more perilous complaint factors in planning successive game patches.

The purpose of this study was to examine the entry behaviors of kindergarten children into peer dyads and the responses of the peer dyads in relation to the sex and sociometric status of the entering child. The subjects were 46 triads(138 children). Each triad consisted of two children of average peer status and one child of high/low peer status, identified by the Peer Rating Scale. The two children of the average peer status were placed in a small laboratory and were given a game to play. After the game had started, the child of high/low peer status entered into the laboratory. The behaviors of the entering child and the responses of the peer dyads were videotaped for 6 minutes. The data were analyzed by sex(2)${\times}$sociometric status (2) ANOVAs and ${\chi}^2$-tests. The results were as follows: (1)Popular children showed more group-oriented statements and fewer waiting behaviors than non-popular children. (2)Popular children elicited more positive responses and were less ignored than non-popular children. (3)The peer group responded positively to the entering child's helping, agreeing, and giving group-oriented statements, and neglected the entering child's waiting behaviors.

Virtual world and simulation need large scale map rendering. However, rendering too many vertices is a computationally complex and time-consuming process. Some game development companies have developed 3D LOD objects for high-speed rendering based on distance between camera and 3D object. Terrain physics simulation researchers need a way to recognize the original object shape from 3D LOD objects. In this paper, we proposed simply automatic LOD framework using point cloud data (PCD). This PCD was created using a 6-direct orthographic ray. Various experiments are performed to validate the effectiveness of the proposed method. We hope the proposed automatic LOD generation framework can play an important role in game development and terrain physic simulation.

Competitive coevolution models, often called host-parasite models, are searching models that imitate the biological coevolution that is a series of reciprocal changes in two competing species. The models are known to be an effective method of solving complex and dynamic problems such as game problems, neural network design problems and constraint satisfaction problems. However, previous models consider only ectoparasites that live on the outside of the host when designing the models, not considering endoparasites that live on the inside of the host. This has a limitation to exploiting some information. In this paper, we develop an artificial adaptation model simulating the process in which hosts coevolve with both ectoparasites and endoparasites. In the model, the endoparasites play important roles as follows. By means of them, we can keep the history on results of previous competition between hosts and parasites, and use endogeneous fitness, not exogeneous. Extensive experiments are carried out to show the coevolution phenomenon and to verify the performance of the proposed model. Nim game problems and neural network problems are used as test-bed problems. The results are reported in this paper.

At the present time it continues to be the smart device released has also been commercialization device accessories accordingly. Such accessories are getting great response to consumers in the form of an external device to a character commercialization design. However, these products are not useful in the functional aspects of using the external form of the device is concentrated only. This study documents the management app to give the game character acts on the application category grouping the ability to efficiently manage the smart device. Research method is to study the existing product released to find out how it works come from the smart device management side, The device app management features added to the game play will be produced based on them.

Babesia spp. were detected from 4 asymptomatic pukus captured on a game ranch in central Zambia in October 2008. Blood smears were examined in 4 species of aymptomatic free-ranging antelopes, namely the puku (Kobus vordanii), reedbuck (Redunca arundinum), bushbuck (Tragelaphus sylvaticus), and kudu (Tragelaphus strepsiceros), and showed the presence of Babesia parasites only in the puku. In the puku, the prevalence of babesiosis was estimated at 33.3% (n=12), while the overall prevalence in all examined animals was 8.5% (n=47). The parasites showed morphological characteristics of paired ring-like stages with the length varying between $1.61{\mu}m$ and $3.02{\mu}m$ ($mean=2.12{\mu}m$, n=27; $SD=0.76{\mu}m$). Both the infected and non-infected pukus showed good body condition scores (BCS), while the dominant tick species detected from all animals were Rhipicephalus appendiculatus, Rhipicephalus spp., and Boophilus spp. To our knowledge this is the first report of Babesia spp. infection in pukus in Zambia. These findings suggest that wildlife could play an important role in the epidemiology of babesiosis in Zambia.

The purpose of the study was to determine the way to improve the school environments especially focused on the elementary school through design gaming with children. Main purpose of the study was to establish the method to find how children experience school environments and the way to find their needs, feelings, and desires of the school facilities. The methods which have been used are design gaming consisted of picture card game, drawing favorable and unfavorable places, and making the wish list. 46 children in Seoul area participated in the study. The main physical environments which have been focused in the study are as follows; the type of classroom, atmosphere of library, indoor and outdoor leisure activity space, indoor and outdoor play area, and the pedestrian way from home to school and from school towards home. Quantitative and qualitative analysis were used to attempt to develop children's preference of each place and their wish about school environments. The results have been summarized based on the general preferences and differences of favorite and unfavorite places. The differences between grades and gender have also been discussed focused on the picture game and drawings of favorite and unfavorite places.

This study examines the potentials and limitations of interactive movies at present by reading the narrative of the interactive movie, through the concept of gamification. The 'quest' of the is to choose an option to play out the story in unpredictable world, and the 'reward' is the hierarchy of the ending. It is necessary to reduce uncertainty between option and ending, intensify playfulness, and provide a variety of discriminative endings in order to make viewers immerse deeper in interactive movies. Such an analysis implies that the intensification of gamification elements may influence the immersion in interactive movies positively.
