Various methods have been proposed to efficiently animate the motion of soft objects in realtime. In order to maintain the topology between the elements of the objects, it is required to employ constraint forces, which limit the size of the time steps for the numerical integration and reduce the efficiency. To tackle this, an implicit method with larger steps was proposed. However, the method is, in essence, a linear system with a large matrix, of which solution requires heavy computations. Several approximate methods have been proposed, but the approximation is obtained with an increased damping and the loss of accuracy. In this paper, new integration method based on harmonic oscillation with better stability was proposed, and it was further stabilized with the hybridization with approximate implicit method. GPU parallelism can be easily implemented for the method, and large-scale soft objects can be simulated in realtime.

Personal information includes information about a living human individual. It is the information identifiable through name, resident registration number, and image, etc. Personal information which is collected by institutions can be wrongfully used, because it contains confidential information of an information object. In order to prevent this, a method is used to remove personal identification elements before distributing and sharing the data. However, even when the identifier such as the name and the resident registration number is removed or changed, personal information can be exposed in the case of a linking attack. This paper proposes a new anonymization technique to enhance data utility. To achieve this, attributes that are utilized in service tend to anonymize at a low level. In addition, the anonymization technique of the proposal can provide two or more anonymized data tables from one original data table without concern about a linking attack. We also verify our proposal by using the cooperative game theory.

This study is a study on the factors of preference for mobile game characters whose intellectual property rights (IP) influence is great. There have been many cases in which user-side research has been conducted on the character's preference factors. However, it is largely macro-divided. Detailed analytical studies are needed because details are overlooked. By classifying the elements of the character, the five-point scale of the recorder also obtains the data through the survey. Detailed factors were analyzed according to the results. Prior studies and results were compared and factors consistent with prior studies were analyzed. Because this study analyzed detailed factors, unlike previous studies of macro view. It is expected to help develop characters in the future.

In this paper, we suggest the Deep Neural Network Model System for predicting results of the match of 'League of Legends (LOL).' The model utilized approximately 26,000 matches of the LOL game and Keras of Tensorflow. It performed an accuracy of 93.75% without overfitting disadvantage in predicting the '2020 League of Legends Worlds Championship' utilizing the real data in the middle of the game. It employed functions of Sigmoid, Relu and Logcosh, for better performance. The experiments found that the four variables largely affected the accuracy of predicting the match --- 'Dragon Gap', 'Level Gap', 'Blue Rift Heralds', and 'Tower Kills Gap,' and ordinary users can also use the model to help develop game strategies by focusing on four elements. Furthermore, the model can be applied to predicting the match of E-sports professional leagues around the world and to the useful training indicators for professional teams, contributing to vitalization of E-sports.

This study is a study on the development of board games using local cultural contents. As a prior study related to this study, basic research on board game development, research on cultural products based on cultural heritage, and storytelling development research using local cultural and tourism resources were considered. Among them, for the main purpose of board games and development process, discussions were conducted on the research methodology of Lee Dae-woong and Oh Seung-taek (2004). As a result, it was possible to successfully proceed with planning meetings, proposal preparation, board game design, board game 3D graphic production process, and prototype development. What is peculiar is that characters (dried persimmons, strawberries, jujube, and salted seafood) containing Nonsan's unique regional characteristics were searched and utilized. In addition, major cultural heritages such as Donamseowon Confucian Academy and Gwanchoksa Temple, designated as Nonsan-si cultural properties, were combined with important treasure hunt contents of board games to enhance interest and education at the same time. The theme of this paper, Nonsan, Finding Lost Treasure, is a new educational alternative that can solve the problems of computer games, and has the advantage of having the nature of community leisure play, not individual play. Based on this board game development research in the future, we intend to expect the results of game production using cultural elements from other regions.

Functional game, which is the combination of play and learning and a futuristic tool, can minimize the dysfunction and maximize the proper functions, and furthermore, has taken root as a new alternative that can change the game industry and game culture. Recently, the focus of game and education markets is shifting to the development of more advanced learning contents, rather than emphasizing the self-control and motivation of users. Along with that, the game market has excluded the socially dysfunctional elements, such as the addiction and learning disabilities, and has witnessed a diversification into the human-friendly entertainment business that emphasizes the mental and physical health and pursues scientific educational effects. In addition, functional games are expanding its reach from the professional sectors - such as medical aide/medical learning, military simulation, health, auxiliary tools, special education and learning tools - to the realm of routine education, mental health, etc., and has seen a steady growth. However, most functional games, which are being currently planned and developed to cope with the special characteristics of the market, have not undergone accurate scientific assessment of their functions and have not proven their effectiveness. An overwhelming proportion of the functional games are being developed based on the intuition and experience of game developers. Moreover, the type of games, which involve the repetition of simple tasks or take the form of simple puzzles, cannot effectively combine the practically interesting factors and the learning effects. Most games incorporate unscientific methods leading to the vague anticipation of improvement in functions, rather than the assessment of human functions. In this paper, a study was conducted to present the measures that could maximize the effects of functional games in relation to the changes in the visual and auditory stimulations in order to maximize the effects of functional games, i,e., the immersion and concentration. To compare the degree of effects arising from the visual stimulation, the functional game contents made in the form of 2D and 3D were utilized. In addition. ultra sound and 3-dimensional functional game contents were utilized to compare the degree of effects resulting from the changes in the auditory stimulation. The brainwave of the users were measured while conducting the experiments related to the response to the changes in visual and auditory stimulations in 3 steps, and the results of the analysis were compared.

As environmental problems such as global warming, and ecocide have a great influence on society, the attention to environmental pollution is being expanded. To solve the environmental problems, the awareness and practice of members of society in question is required. However, it has been found that few people are participating in practising environmental protection in real life. Our main goals are to show that Gamification has great potential in delivering messages for public interest and to suggest guidelines for researchers and public contents developers who engage in designing in relation to Gamification. Based on the domestic and foreign theoretical investigations, we found that Gamification mechanism made based on psychological mechanism of users aims at public interests' value by maximizing motivations of users and spreading social relationships among people. As shown in the case study, if contents are developed by reflecting the elements which stimulate challenging of users, the elements which can express their opinions, and the elements of altruism which form the sympathy in the development of public interest contents in the future, practical participation of people to solve social problems can be expected.

Thesedays, not only a quality of a product but also a design of it plays an important role. Throughout this analysis, I would like to discuss how a design of package works in the cosmetics with the fact that low cost cosmetics sales better than high cost cosmetics. In this research, there are five samples each for Korean and Chinese low-costed cosmetics to yield a result about an element of package design. Based on that result, there was an survey about two different package design followed by the research problems. Throughout research, an attention and familiarity of package which was considered of characteristics of China was more effective on Chinese consumers. In order to activate the content market of cosmetics, it is utilized to manufacture taking into account the maximum of the design elements in the package design is a conclusion that affect the time of purchase. In this paper, one in which I hope to help in the development of being utilized as a basis article content market industry for pre-market research foray into the Chinese market is South Korean cosmetics.

Indonesia has the largest potential mobile payment (m-payment) market in Southeast Asia. The government has realised this through Government's National Non-Cash Movement to increase its adoption. This is then followed up by advocating its adoption massively. However, for this movement to be a success, ensuring its continued use is critical. Various studies have attempted to contribute to this issue. Incorporating game elements into the application that brings benefits and satisfaction to its user is envisaged as one of the most feasible ways. This study, therefore, sets out to investigate the effects of gamification on the m-payment application, which drive the intention to continued use by employing the Uses dan Gratification Theory (UGT). A total of 826 m-payment users were gathered to be analysed using Structural Equation Modelling. The results show that utilitarian, hedonic and social gratifications have significant effects on the continuance usage intention of m-payment. Theoretically, this study contributes to the literature by showing that gamification applied in the payment significantly affects the m-payment continuance usage intention. Practically, this research informs the m-payment providers to maintain the gamification elements in their applications to ensure their sustainable use. Limitations and future research directions are also discussed.
