In this paper, we investigate and analyze the application of VV&A on the development of war-game models which were developed in Korea. Then we propose VV&A framework which comprises VV&A basic model, VV&A reference model and a supporting tool. The VV&A basic model consists of VV&A process, products and methodologies. The VV&A reference model includes VV&A check lists for each VV&A activities, an assessment model of VV&A execution level and VV&A process maturity model. The VV&A supporting tool is to document and manage VV&A products. The proposed VV&A framework can be used as the foundation of VV&A plan on its execution.

The study was to find out the effects of computer game and stretching on muscle tone and concentration. The subjects were 30 adults, who were divided into 15 stretching group and 15 control group after applying computer game for 120 minutes. The subjects measured muscle tone and concentration before experiment, the same measurements were made before and after applying the stretching. The muscle tone was respectively measured after 60 minutes and 120 minutes of computer game. The results showed that muscle tone increased significantly after 60 minutes and 120 minutes of computer game, and significantly decreased in the stretching intervention group. Concentration increased significantly after computer game, but there was no significant difference after application of stretching. In this study, computer game increased muscle tone and concentration, and stretching decreased increased muscle tone. Therefore, proper stretching after computer games will reduce musculoskeletal diseases caused by increased muscle tone, and development of appropriate game contents will be an effective tool for concentration training.

This study investigates the effectiveness of computer programming with KODU on problem-solving abilities of elementary school students. Diverse tools were developed for novice programmers to become more easy and comfort in learning a computer programming. Among them, KODU has focused on facilitating the programming of various multimedia applications to create games, animations and music videos etc. It is expected that KODU will help elementary school students to improve their problem-solving abilities through creating their own games, animation, and music etc. In this paper, we developed the educational program using KODU for teaching the elementary school students. The developed programming course was offered at the 5th grade students of a elementary school in Seoul and a total of 27 elementary school students were participated in our programming courses. Most of the students stated that the course was interesting, and their problem-solving ablilities were improved after the course from March 2014 through May 2014.

AGT 시스템은 복잡한 대규모 시스템이며 이 시스템에 도입된 무인운전의 운영 개념은 한국 철도 기술의 환경에서는 처음 시도되는 기술이다. 게다가 신호시스템을 무선 기술을 이용하여 구현해 한다는 요구사항이 추가되어 신호시스템 개발은 더욱 도전적인 문제가 되었다. 이와 같이 실천하기 어려운 요구사항이 많은 무선열차 제어시스템 개발의 위험을 줄이기 위해 시스템공학팀은 전산지원 시스템공학 도구를 사용한 재공학의 개발공정을 수행하도록 하였다. 본 연구에서는 기존의 정적인 데이터모텔에 추가하여 시나리오 기반으로 동적거동 분석을 수행하여 기능 모델을 구축하였고 기능 모델을 토대로 한 시스템 아키텍처를 구성하였다. 특히 기능 요구사항의 취약성을 보완하기 위해 CORE의 FFBD(Functional Flow Block Diagram)기능을 활용하여 열차 운행 중 발생할 수 있는 여러 가지 시나리오를 분석함으로써 기능 모델의 완전성의 기여하였다. 이는 정적인 데이터 흐름 다이아그램(DFD:Data Flow Diagram)이 가지는 한계를 모델 기반 시스템공학 도구에서 지원하는 동적인 기능 분석을 수행하여 보완함으로써 모델의 충실도를 높였음을 의미한다. 이를 통해 기능의 오류를 개념단계에서 최소화함으로써 기술 위험이 높은 제품을 개발할 수 있다는 것을 확인하였다.

The generalization trend of smart phones have brought many smartphone games into daily lives. These games are mainly dependent on the interactions on the display of the phone using finger touches. On the other hand, functions for detecting the positions and actions of the phones such as gyro-sensors have been rapidly developed over the former orientation sensors and acceleration sensors. Though it has become technologically possible to detect the users' motion via the smartphone devices and to use the phone device directly as the game device, it is hard to find the actualized cases. This paper proposes a new paradigm including basic frameworks and algorithm for the games combining the motion recognitions and mutual communications on the smartphones and finally presents the details of its implementation and results.

This study suggests a design for an analytical software program and method for multitasking e-sports viewing through the web using an eye tracking device. To fulfill this task, we designed a Window of Interest (WOI) to measure and record visually on a screen wherever numerous multitasking activities occur. In addition, we developed an OBS (Opensource Broadcaster Software) plug-in that records and streams participant viewing behavior patterns in real time. The purpose of this study is as follows. First, unlike existing tools that limit web interface recording to still images, the developed tool can record dynamically via media such as videos. Second, when several windows are processed on a screen, the tool can accurately record the gaze positions of the participants. Lastly, the tool can enhance the objective validity of the data as it can be implemented in natural situations. Therefore, this study can trace natural viewing patterns and behavior as we do not create artificial experimental environments and stimuli.

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 examined the education effect of business simulation game. It was found that managers who were educated and trained with business simulation game were very satisfied with a business simulation game. Based on the statistical results, the method of business education using business simulation game was also suggested.

In the mobile gaming market, it is desirable for a specific content to be served on various platforms. Recently, it is a very important issue in the market for mobile games. This problem incurs extra cost, because we need to redevelop existing contents to be executed on another platforms. Moreover, the release of a new platform has spent much more effort and cost developing many contents in short period of time. Therefore, we need to research about translation techniques that enable the existing contents to run on a different platform. In this paper, we propose translation techniques for mobile games. The techniques can be applied on converting mobile contents to runnable contents on a new platform. To realize it, we design and implement a source-level contents translator which is targeting Android platform using the suggested techniques. Our source-level contents translator is implemented systematically by applying compiler theory. Also, we solve partially translation problems between different programming languages. The translator has been implemented separately divided into three tasks such as kernel porting, library mapping as well as language translation. We expect these techniques to increase utilization of existing mobile games and contribute to vitalizations of mobile contents industry.

Illegal game players' hacking and propagation of malignant code in online game exposes privacy of online game customers. So, online game companies have to support the standardized systems and operations of customers' privacies. Since online game companies implement authentication of information protection, which focuses on assets or physical, systemic security, they need a more professional system that is related to protection of individual privacy. We analyzed the individual information protection system, which includes ISO27001, ISMS of KISA, GMITS, ePrivacy, online game privacy protection guide, and BS10012. Using the suggested systems, we proposed the systemic tools that measure the level of individual information protection, which includes process and check items of each phase.
