"The Legend of Princess Bari" mostly accepted the story and character of the Myth of Baridegi. Each player has their own storyline from the beginning. "The Legend of Princess Bari 2" was released less than a year after the release of "The Legend of Princess Bari 1," but it fell short of creating additional contents from its original version. However, "The Persona4" applied and transformed the Myth of Inajagi & Ijanami according to our present time. The protagonist's each have their own designated "Persona" skills and Ijanami is their ultimate enemy. Interestingly, each player starts with the same storyline but all have different endings. Based on the existing story elements of Persona series, various genres of games were produced through remakes and spinoffs.

This paper propose a practical algorithm to reuse and expand the objects. This algorithm is based on the Motion Path Modification rules. We focus on reusing of the existing motions for synthesizing new motions for the objects. Both the linear and the nonlinear curve-fitting algorithm are applied to modify an animation by keyframe interpolation and to make the motion appear realistic. We also proposes a framework of the scenario-based 3D image synthesizing system that allows common users, who envision a scenario in their minds, to realize it into segments of a cool animation. The framework is useful in building a 3D animation in game programming with a limited set of 3D objects.

This paper deals with an information security problem that involves the strategies of both an attacker and an administrator of a web-based system. A game-theoretic model for the problem, based on an Stackelberg game environment, is presented. In the model, the administrator selects a set of anti-virus vaccines to cope with potential system attackers and the intruder chooses attacking modes that are most effective against the administrator's chosen set of vaccines. Moreover, the model considers a number of practical constraints, such as a budget limit on the vaccine purchase and a limit on the system performance. In addition, two different scenario analyses are provided, based on the results of the proposed model applied to a simulated pseudo-real-world data.

73 percent of online games in Korea hold perspectives of medieval times in them. So far in history, about a millennium in medieval times is said to be a period of darkness and savagery, but it is newly revived in the digital virtual world. Such phenomenon is paradoxical and meaningful to often bring out 'medieval times' as a theme for online games, which are revealed by up-to-date technologies in present days. This research examines the background of views of medieval times appeared in online games and how they are realized. Medieval fantasy games have appeared because people dream about escaping from pre-modem times and have fantasy about medieval times. Moreover, perspectives of medieval times have enormously influenced background epics, quest stories, creation of characters in a game scenario. The dual structure having coexistence of nature and super naturalness acts an important role to set up the epic for medieval fantasy games. And medieval romance literature, which has a three-step quest narrative of 'targeting - adventure and fight - achievement' is reflected in a quest story of medieval fantasy games. The strict pyramid system represented by feudalism forms a meaningful metaphor for designing characters, and players organize communities for online games through horizontal collective consciousness in such vertical system of history at the same time.

The U-Healthcare era has evolved with the development of the Internet of things (IoT) in the early stages of being connected as a society. Already, many changes such as increased well-being and the extension of human life are becoming evident across cultures. Korea entered the growing group of aging societies in 2017, and its silver industry is expected to grow rapidly by adopting the IoT of a super-connected society. In particular, the senior shift phenomenon has resulted in increased interest in the promotion of the health and well-being of the emergent silver generation which, unlike the existing silver generation, is highly active and wields great economic power. This study conducted in-depth interviews to investigate the characteristics of the new silver generation, and to develop the design for a wearable serious game that intends to boost the interest of the elderly in exercise and fitness activities according to their personalized physical training regimes as prescribed by the U-Hospital service. The usage scenario of this wearable serious game for the 'U-silver generation' is derived from social necessity. Medical professionals can utilize this technology to conduct health examinations and to monitor the rehabilitation of senior patients. The elderly can also use this tool to request checkups or to interface with their healthcare providers. The wearable serious game is further aimed at mitigating concerns about the deterioration of the physical functions of the silver generation by applying personalized exercise prescriptions. The present investigation revealed that it is necessary to merge the on / off line community activities to meet the silver generation's daily needs for connection and friendship. Further, the sustainability of the serious game must be enhanced through the inculcation of a sense of accomplishment as a player rises through the levels of the game. The proposed wearable serious game is designed specifically for the silver generation that is inexperienced in using digital devices: simple game rules are applied to a familiar interface grounded on the gourmet travels preferred by the target players to increase usability.

The commercial success of the game has also led to animation of the original game, especially the live version of The Street Fighter II in 1994 and a variety of videos of the game-based version, 2D Animation and 3D Animaion until now. But animations are not always successful because they are based on popular and commercially successful games. That's because when the original game was remade into an animation, the difference between the narrative structure of the original game story and the setting of the game and animation is striking. Nevertheless, a feature-length animation based on the Angry Birds game, which was released on May 19, 2016, has also been a huge commercial success, with this paper analyzing the case applied to the 12th stage of Christopher Vogler's hero's journey, Aengibird the Movie, and discussing the way in which the animation developed based on the game compared with other animations. Christopher Vogler, a Hollywood playwright, analyzed the structure of popular-loved movies based on the common narrative of the myth as the main motif of the mythologist Joseph Campbell. His narrative style is a hero's journey, using a total of 12 stages of epic narrative structure to help the protagonist find himself and achieve what he wants. Foreign heroes, adventure films as well as animations from big studios like Disney, Pixar, and Ghibli are using the story-development method of this Christopher Vogler.

Most of the previous game development has proceeded in the approaches of the temporal-oriented synchronization because of producing game objects by using general authoring tools, and ad hoc or trial and error methods has been devised for representation of spatial concept. This paper is a study on the unification notation for spatio-temporal synchronization to conquest this fault. First of all, we classify game space as temporal object, spatial object, absolute/relative spatio-temporal space. The spatio-temporal relationships are divided into temporal extent, temporal location, spatial extent, and spatial location. In the paper the temporal and spatial relationships of game scene are defined to represent the synchronization, and we propose new unification notation by temporal and spatial concept to represent two concepts putting emphasis on space. Their relationships are presented on 3D by creating time axis related with time in scene unit of the two dimensional plane in the pivot on space. The usability of this representation method are shown by applying examples of game scenario.
