Due to the fast development of information technology, a variety of edutainment software has been used in the field of business education. One of them is Business Simulation Game that the business game domain and the information technology is definitely associated. A lot of business simulation game have been developed and used for many courses of colleges and corporate training in USA and EU. However, education program based on business simulation game has not been activated in Korea. This paper introduce a business simulation game developed by joint effort of business professors and a software firm for last three years and suggest the method of business education using this business simulation game. First of all, the development process, architecture and procedure of business simulation game are summarized. From a perspective of business education, the effect and advantage of business simulation game, sample syllabus, course outlines, users, missions and evaluation method are also addressed.

This study describes a system which makes children use a cooperation study for the education of a library use and applies SDG technology to this cooperation study SDG means a system which is able to do a cooperation work as a multi-inputting device in a computer display. Through the use library utilization education system based on SDG, learners study simultaneously and collaborately. On this thesis. We embodied the understanding of the decimal classification of Korea and the arrangement of a bookshelf and the study of the location tracking as a game style based on an existed study that a cooperation study used SDG is more superior that an individual study used a single device. Librarians through this system will be able to easily and interestingly instruct children for the use of a library.

The prisoner's dilemma game which is a representative example of game theory is being studied with interest by many economists, social scientists, and computer scientists. In recent years, many researches on computational approaches that apply evolutionary computation techniques such as genetic algorithms and particle swarm optimization have been actively conducted to analyze prisoner dilemma games. In this study, we intend to evolve a strategy for a iterated prisoner dilemma game participating two or more players using three different binary particle swarm optimization techniques. As a result of experimenting by applying three kinds of binary particle swarm optimization to the iterated prisoner's dilemma game, it was confirmed that mutual cooperation can be established even among selfish participants to maximize their own gains. However, it was also confirmed that the more participants, the more difficult to establish a mutual cooperation relationship.

As the number of Internet users has increased, the uses of social networking sites (SNSs) and online games have become universal activities across gender and ages. The extensive distribution and the usage of the Internet are beneficial to our society, but its adverse effects, such as Internet addiction, which refers to uncontrollable excessive Internet use, are becoming prevalent. Relevant social costs are also becoming troublesome. SNS and gaming addictions have negative effects on one's life, causing significant social problems. To illustrate different facets of these addictions, Problem Behavior Theory is adopted in the study. How self-esteem and perceived family environment affect SNS addiction and gaming addiction is addressed. The main subjects are Korean university students in their 20s who use SNS and play online games. The relationship between SNS addiction and gaming addiction is also addressed.

Excessive use of the internet and smart phones have become a social issue. The level of engagement has both positive and negative effects such as good performance or indulgence phenomenon, respectively. This study was to develop an algorithm to determine the engagement state based on cardiovascular response. The participants were asked to play a pattern matching game and the experimental design was divided into cooperation and competition task to provide the level of engagement. The correlation between heart rate and amplitude was analyzed according to each task. The regression equation and accuracy were verified by polynomial regression analysis. The results showed that heart rate and amplitude were positively correlated when the task was a game, and negatively correlated when there was a reference task. The accuracy of classifying between game and reference task was 89%. The accuracy between tasks was confirmed to be 76.5%. This study is expected to be used to quantitatively evaluate the level of engagement in real time.

The tangible virtual heritage environment employs a tangible interface to increase social interaction and engages user's understanding of cultural heritage with the activities in the virtual environment. Tangible Moyangsung is an tangible virtual heritage environment of a Korean war-defensive castle Moyangsung, and it allows a group of users to collaboratively play the tangible interface for fortifying the broken walls. This paper suggests an overview of cultural meanings behind Moyangsung and represents the details in the design and implementation of the Tangible Moyangsung system. It will also discuss improvements and further research directions.

To discover an up-to-date way of learning through smart devices, our research studied the impact of Web 2.0 learning environment using smart devices on learner's academic achievement and learning attitude. We performed an experiment during 7 weeks based on elementary school 5th grade Society curriculum and the results were analyzed. Followings are the summary of results: The experimental group obtained higher academic achievement and also showed more improvements in self-directed learning attitude than the control group. Therefore, the usage of smart devices in Web 2.0 environment has positive effects on the academic achievement of students and their self-directed learning attitude within collaborate learning courses.

Many web-based simulation environments have been proposed to create models and execute simulation through the Web. Although web-based simulation has the advantage of utilizing many computers connected to Internet, overhead of the web server and heavy traffic caused by Java RMI degrade the performance and scalability of simulation. In this paper, we design and implement web-based distributed simulator using Java for the scalability and performance. In addition, we can apply the proposed simulator to create model server and client engines in online game. We apply the proposed simulator to simulate ATM switch queueing model.
