정보화 사회에서의 일원으로 꼭 갖추어야 할 정보통신윤리 덕목들은 기존 산업화 사회에서의 교수-학습방법으로는 부적절하다. 덕 교육 (Virtues Education)은 행위자가 교육의 중심이 되어, 인지 정의 행동의 통합과 공동체주의를 중요시 여겨 학습자 스스로 윤리를 체득하도록 하는 장점이 있다. 본 연구에서는 덕 교육의 장점을 기반으로 학습자가 보다 재미있고 쉬운 학습을 통해 정보통신윤리의 능동적이고 자연스러운 체득이 가능하도록 게임 모형을 개발하였다. 본 게임 모형은 문제 사태를 확인하고, 그에 관련된 규범을 찾고, 규범의 의미와 근거를 찾은 후, 판단을 예측하고, 판단하여 미션을 해결하는 모형이다. 본 모형의 장점 (특징)은 다음과 같다. 첫째, 학습자가 쉽고 재미있게 정보통신윤리 학습을 할 수 있다. 둘째, 게임을 진행하며 윤리의식을 교사가 전달하는 것이 아닌, 학습자 스스로 체득하게 할 수 있다. 셋째, 정보화 사회의 구성원으로서 알맞은 가치관을 확립하여, 정보화 사회의 역기능에 대해 올바르게 판단하고 실천할 수 있다.

본 연구는 최근 개발된 다양한 저비용 센서와 기계 학습 알고리즘을 이용한 게임을 위한 사람 팔 제스처 인식에 관한 것이다. 게임의 입력으로 사용할 수 있는 동작 10개를 정의하고, 이러한 동작들을 센서에서 수집된 팔 관절의 좌표를 추적하여 전처리했다. 자료의 시간성을 고려하여 HMM(Hidden Markov Model)을 학습 알고리즘으로 사용하였으며 제안한 방법의 유용성은 실험을 통해 검증했다.

The purpose of this study is to identify the factors influencing the user's continuous usage intention of computer games. A research model was developed which shows that the independent variables of value, expectation confirmation, perceived enjoyment affect user satisfaction and continuous usage intention. To test the six hypotheses, survey data were collected from 104 respondents, and hypotheses tests as well as a confirmatory factor analysis were conducted using a partial least square analysis tool. The statistical analysis result showed that expectation confirmation had a significant positive effect on satisfaction, and satisfaction also had a strong positive effect on the game user's continuous usage intention. Perceived enjoyment showed a highly strong positive effect on satisfaction. In addition, satisfaction was found to have full mediation effects in the relationship between expectation confirmation and continuous usage intention, and perceived enjoyment and continuous usage intention respectively. This result provides an important implication that continuous usage intention occurs through user satisfaction, and also indicates the contribution of this study for the game industry. Another contribution of this study is to introduce critical independent variables from the marketing and information technology domains in order to explain continuous usage intention of computer games.

In this paper, we evaluated educational effects of H-STEAM group play contents(a course) and tried to suggest a convergent model for college liberal art curriculum. We opened a mixed course(math, art, engineering, and humanities) with team teaching for this purpose. For the test, we collected data from survey, K-W-L sheet, and reflection paper from 23 students who enrolled in this course. Students should do a team project during the course, propose a new group game, and write K-W-L sheet at the end of each session and reflection paper at the final stage. As a result, it is said that H-STEAM group contents had an effect on students' satisfaction and achievement. During the course, students made academic efforts and were able to construct convergent knowledge from the four fields. From this study, we are sure that H-STEAM contents can play a substitute role for the traditional liberal arts program and innovate the curriculum for the knowledge convergence society.

The net shape effects by the various vectors in underwater. Each particle of the net calculating the effect of all vectors augments an accuracy and reality. But, the time complexity becomes larger because of huge calculation. The previous techniques reduced a physics reality. And embodied the underwater virtual reality which augments visual reality with simulation. In this paper, parallel processing the particles, it embodied the simulation which is satisfied a physical reality and time reality. The parallel processing used the OpenMP, and the reality graphic expression used the OpenGL. The simulation which this paper Proposes will be the possibility becoming the fundamental data for a model analysis or a specialist system from game and marine field.

Computer simulation has used to a area of military training in recent years. Computer simulation endow a military nan with field raining such as combat experience without operating combat strength or capabilities. To samely construct simulation environment against actual combat environment is to well construct ㏈ to operate war game model, associate among federates on network. we construct virtual combat environment enabling to efficiently manage network traffic among federates(or active nodes) on active network that construct virtual military training spare such as urgent combat field needed to rapidly transfer combat information including image and video.

The Generative Adversarial Networks, as one of the most creative deep learning models in recent years, has achieved great success in computer vision and natural language processing. It uses the game theory to generate the best sample in generator and discriminator. Recently, many deep learning models have been applied to the security field. Along with the idea of "generative" and "adversarial", researchers are trying to apply Generative Adversarial Networks to the security field. This paper presents the development of Generative Adversarial Networks. We review traditional generation models and typical Generative Adversarial Networks models, analyze the application of their models in natural language processing and computer vision. To emphasize that Generative Adversarial Networks models are feasible to be used in security, we separately review the contributions that their defenses in information security, cyber security and artificial intelligence security. Finally, drawing on the reviewed literature, we provide a broader outlook of this research direction.

Since the supply of smart phones, a change in mobile environment brought a turning point called a mobile generation. Smart mobile office is a combined form of smart phones' new mobile environment and its social media. A construction of mobile office environment using smart phones brought revitalization of the smart phone market. CRM construction also became new requirements for a customer management. However, based on the current information system audit standard, check fields or check lists are insufficient to apply to audit for CRM construction in a smart mobile office environment. Therefore, this paper proposes a model for auditing CRM system construction in smart mobile office environment. It proposes audit domain and check lists of CRM construction. It also verified whether the proposed model is suitable or not by doing a survey if deduced audit domain and check lists correspond with the purpose of the CRM construction audit during smart mobile office environment. As the result, this study appear to have more than average satisfaction the suitability results were.

As application development environment changes rapidly, importance of user interface design is increasing. Usually, most of designers are clustering by subjective method of individual to define objects that have relativity in design interface. But, interface which is designed without particular rules just adds inefficiency and complexity of business to user who use this system. Therefore, in this paper, we propose an object oriented design model that allows for flexible development by formalizing the user interface prototype in any GUI environment. The visual cohesion of the user interface is a new set of criteria which has been studied in relation to the user interface contents, and is founded on the basis of the cohesion of the interface as defined using basic software engineering concepts. The visual cohesion includes the issue of how each unit is arranged and grouped, as well as the cohesion of the business events which appear in the programming unit. The interface will become easier to understand and use if the business events are grouped by their inter-relevance within the user interface.

Most of the computer to implement a Augmented reality 3-D, or a graphic or visual means through the virtual space. The participants in the Augmented reality immersive virtual reality and virtual reality, the process proceeds to change the world. In particular, the field of children's games and Augmented reality fits well with the technical characteristics of the children that may lead to more interesting and creative sector is pointing to. In this study, children's games in order to maximize learning effectiveness of board games and Augmented reality technology, take a look at the characteristics of the children's educational program is to propose a new model proposal.
