Recently, the drone industry is rapidly expanding as it is suggested that it will be used in various fields. As the size of the drone market grows, interest in drone-related certificates is also increasing. However, the current drone-related qualification system and education system are insufficient. Thus this study, analyzed the necessity of drone training, the features of functional games, and the effectiveness of educational training using AR through related technical studies to solve the practical difficulties of drone educational training. Later, drone educational training game contents using AR were divided into practice mode and test mode based on the drone national qualification course practical test, and the result screen was displayed at the end of the curriculum so that players could learn by level and evaluate the results on their own. In addition, constructed a hybrid processing system and network and AR operation system for response rate and response speed, implemented drone training game contents utilizing AR based on the design contents. It is expected that the use of game content using AR presented in this paper for drone training will further alleviate environmental difficulties and improve the sense of immersion in play, which will lead to a more effective drone educational training experience.

With the diversification of payment methods and games, related financial accidents are causing serious problems for users and game companies. Recently, game companies have introduced an Fraud Detection System (FDS) for game payment systems to prevent financial incident. However, FDS is ineffective and cannot provide major evidence based on judgment results, as it requires constant change of detection patterns. In this paper, we analyze abnormal transactions among payment log data of real game companies to generate related features. One of the unsupervised learning models, Autoencoder, was used to build a model to detect abnormal transactions, which resulted in over 85% accuracy. Using X-FDS (Explainable FDS) with XAI-SHAP, we could understand that the variables with the highest explanation for anomaly detection were the amount of transaction, transaction medium, and the age of users. Based on X-FDS, we derive an improved detection model with an accuracy of 94% was finally derived by fine-tuning the importance of features that adversely affect the proposed model.

Casual games are easy in terms of control and mode, and thus everyone can enjoy them in their free time. Character games, in particular, feature a variety of cute and attractive characters. Such character games are now available for smartphones, which are used by a large number of users, as well as for PCs. This paper is aimed at demonstrating the design of 2D side-scrolling casual shooting games utilizing Unity 3D Engine, which can be manipulated on smartphones. Unity 3D engine was used because it supports multi-platform with low costs, and it makes it possibile for games to be operated on various platforms using a single program source code. This approach is unique because the design of the games uses cute characters, attractive concepts and easy control, targeting users in their 10s or 20s, unlike existing shooting games that are serious.

Objective: The purpose of this study was to explore the effects of a senior functional game (Rejuvenescent village) on cognitive function, instrumental activities of daily living (IADL), depression, and life satisfaction in Korea. Methods: An one-group pretest-posttest design was used in this study. Data were collected twice (at the beginning and the end) from 100 elderly adults in S city who played "Rejuvenescent village" 8 times (twice per week, one hour per session) for a month. Also they completed questionnaires on their cognitive function, IADL, depression, life satisfaction, and general characteristics. The data were analyzed using SPSS 20.0 programs. Results: The mean age was 70.06(${\pm}3.77$) years, with a range of 65-80 years old. Among 100 subjects, 21% were male and 85% were young old. There were statistically significant differences in cognitive function (t=-3.32, p=.001), IADL (t=1.98, p=.049), and life satisfaction (t=-2.15, p=.034). Although there was no statistically significant difference in mean depression score (t=1.06, p=.292), categorized depression was statistically significant (${\chi}^2=62.97$, p<.001). Conclusion: The findings in this study show that the serious game (Rejuvenescent village) was effective for older Koreans' cognitive function, IADL, depression, and life satisfaction. Thus, we need to consider senior functional games to get health benefits by making elderly adults active with enjoyment.

This paper was intended to present a way to incorporate Korean content and products of Korean brands into functional coloring games that color them for the continued development of digital hallyu at this time of the world's derivation, as shown by the Korean Wave, a word that means more and more people like Korean culture worldwide. For the development of the Korean digital convergence functional game industry that can solve users' leisure time, we will compare and analyze the advanced image cuts provided by coloring games that have been commercialized and serviced, and seek ways to utilize the image of Hallyu contents that are not provided in existing coloring games. In the image cuts used in functional coloring games, we will find ways to utilize differentiated Hallyu content image cuts and study and present the direction of development of aesthetic elements of coloring games. Research on Korean Wave content, which has made use of our own aesthetic elements, should continue, and functional games using digital mobile device devices and game content elements utilizing Korean images in the Korean game industry will help spread Korean pop culture and digital Hallyu.

Game technologies are now applied in various engineering areas such as the simulation of surgical operation or the implementation of a cyber model house. One of the essential and important technology in these applications is cutting of the 3D polygon model in real time. Real-time cutting technology is an essential technology needed to implement the simulation of a building demolition or a car assembly for training or educational purpose. Previous cutting method using the conventional BSP-Tree structure has some limitations in that they divide the whole world including the 3D model and its environment, only into two parts with respect to an infinite plane. In this paper, we show a technique cutting the 3D model in a finite extent in order to solve this problem. Specifically, we restricted the cut surface in a finite rectangular area and constructed the mesh for the divided surface. To show the usefulness of our partial cutting technique, an example of the dismantling process simulation of a nuclear reactor polygon model was illustrated.

Dementia once occurred is known to be mostly irreversible but can be treated only if it is detected early; especially vascular Dementia. Thus, in this paper we have developed Dementia diagnosis and care application through inter-working between biometric sensors and smart phone. With developing serious game for the demented elderly, we proposed ons-stop solution for Dementia; smart-phone application with diagnosis, prevention and mitigation of Dementia. Since the proposed game for mitigating Dementia requires sense of space and balance using both arms instead of operating simple arrow button, a treatment effect for Dementia will be doubled. If we tried to forestall, ease and cure Dementia with the proposed application. the social losses from Dementia would be minimized as a result.
