The purpose of study was to develop distance education programs that combine the characteristics of the programs for the math gifted students. To this end, the first is to establish the standards for the development of distance programs for the math gifted students. The second is to develop the distance education programs for the elementary school math gifted students according to the program procedure models for distance education. The third is to apply the programs developed to actual distance education field and analyze the results to verify the validity of the programs. This program can increase high-level mathematical thinking power even though it is the distance education, not the face-to-face education. Second, this program make contributions to active mathematical communication through newsgroup or reflective journals. Third, the use of Diffy Game facilitates the selection of in-depth contents, which will in turn enable the development of intensive programs.

Since service competition among global supply chains became intensified, market-oriented system, instead of the existing cost-based system, for port service pricing has been strongly recommended in order to enhance their long-term viability and competitiveness. The Owen value of cooperative game frameworks allows us to apply a market-oriented pricing theory for the port pricing in the case of Gwangyang port to verify its usefulness. The analytical results of this paper suggested some solutions in the problem of berth-based cost allocation by a characteristic function and also showed the proper relative weights of factors to derive the quay use index by Budescu(1993). We also suggested a favorable port pricing system to major shipping firms as well as a discount port pricing system for their strategic alliance. To put it differently, the results of this study enable the port managers to make out some strategic port pricing system like the reasonable discount in port charge for the larger ship owners using the ports frequently.

With the consistent development of the 3D application technique, visuals are available at more realistic quality and are utilized in many applications like game. In particular, interacting with 3D objects in virtual environments, 3D graphics have led to a substantial development in the augmented reality. This study proposes a 3D user interface to control objects in 3D space through virtual two-view method using only one camera. To do so, homography matrix including transformation information between arbitrary two positions of camera is calculated and 3D coordinates are reconstructed by employing the 2D hand coordinates derived from the single camera, homography matrix and projection matrix of camera. This method will result in more accurate and quick 3D information. This approach may be advantageous with respect to the reduced amount of calculation needed for using one camera rather than two and may be effective at the same time for real-time processes while it is economically efficient.

Recently, with the high interest of machine learning, the need for educational controllers to interface with physical devices has increased. However, existing controllers are limited in terms of high cost and area of utilization for educational purposes. In this paper, motion control controllers using brain waves are proposed for the purpose of students' machine learning applications. The brain motion that occurs when imagining a specific action is measured and sampled, then the sample values were learned through Tensor Flow and the motion was recognized in contents such as games. Movement variation for motion recognition consists of directionality and jump motion. The identification of the recognition behavior is sent to a game produced by an Unreal Engine to operate the character in the game. In addition to brain waves, the implemented controller can be used in various fields depending on the input signal and can be used for educational purposes such as machine learning applications.

The background fort this study is related to the concept of modern time and space which has been extended from physical space to virtual space in the present times witnessing the advent of the Fourth Industrial Revolution. Based on visual tactility and illusion in virtual reality, we intended to present the possibility of the interactions as realistic as the interactions occurring in reality. Regarding the scope of this study, we analyzed the relationship between illusion in game space and immersion in interactions based on the games used frequently among current virtual reality contents. The results of the study showed that the interactions in virtual reality occurred within the space converging the time and space and that the illusion of digital images had realistic position of reality without original. Research which investigates the interaction in virtual space and media projection method for real space and virtual space will provide useful basis for promoting technological development based on novel methods differentiated from existing image grammar and for identifying the content utilization methods.

As the growth of the live streaming service market is accelerating due to COVID-19, the number of downloads and reviews of live streaming mobile applications is also rapidly skyrocketing. This study is to research game streaming applications using Twitch reviews as database. A total of 8 topics are extracted through LDA topic modeling and 7 out of them are detected to be inconvenience factors. Then, to pinpoint the main inconvenience factors, co-occurrence analysis is used in order to find out main factors. Finally, based on previous studies, several solutions are provided, which can solve the inconvenience factors(advertisement, UI design, technology problems) as well as strengthening digital competitiveness. This study will serve as an opportunity to improve digital competitiveness not only for Twitch but also for other game live streaming service companies in the future.

As smartphones have become widely used, topics of smartphone become a hot research subject in IT technologies. Many applications have been developed for the smartphone and the application market has become more and more increasing. However here are few studies or application developments on Korea's traditional games. In this paper we developed Korea's traditional board game Gonu. People who are young or old can play the game. We expect that many applications which related with Korean culture are developed on the smartphone environment.

The avatar gender, the basic element that constitutes the identity of the MMORPG player, can be created by the player due to the nature of the game through the system provided within the game. Thus, players exhibit a different attitude from reality regarding avatar gender. Gender customization in virtual space is an expansion of the identity in an effort to express one's identity in various ways. A number of users manage avatars with the opposite gender where it was found that male players preferred the female avatar persona. In this study, the player attitudes regarding gender was analyzed using Q methodology and the motivational factors for gender swapping and the generalization phenomenon was determined. This study will be significant as critical standards in the usability evaluation of the MMORPG customization system.

The purpose of this study is to investigate the effect of reading education program for high school on students' self-esteem and reading attitude and satisfaction of students through the whole reading education process. The program that consists of 10 classes was developed and reading education was conducted. Through analysis of pre-post variance in self-esteem and reading attitude, effects of reading education has been proved. Also, satisfaction as evaluation about the whole reading education process was surveyed. As a result, it was found that reading education that uses program based on board game affects high school students' self-esteem and reading attitude, enhances reading attitude and promotes reading motivation.
