Most cultural contents currently we face are not suitable for associating with state of arts and high technology as simply providing one-sided learning. Pictures and movies of cultural contents also sees to utilize for efficacy of cultural education. There are still some limitations to draw interest from users when providing one-sided learning for cultural study, which aims to only deliver knowledge itself. In this paper, we propose interactive HMD VR cultural contents that can support more experience to get rid of aforementioned limitations. To this end, we first select quite interesting and wellknown cultural contents from world wide to draw more attention and effect. To increase immersion, presence and interactivity we have used HMD VR and Leapmotion, which intentionally draws more attention to increase interest. The cultural contents also facilitate augmented information as well as puzzle gaming components. To verify, we have carried out a user study as well.

For the usage of the different standard technology among DRM vendors, the DRM technologies in today could not guarantee the interoperability between the digital contents and digital devices. While users have been guaranteed the protection of contents, they have to put up with the limitation and inconvenience. The Superdistribution methods that InterTrust has proposed is the content distribution technology which is possible to use the content only by the user authentication with the license regardless of the acquisition of the DRM contents. However, it need a additional license with re-authentication from DRM server when the original contents need to be moved to other devices from the own device. In this paper, to reduce the inconveniences of re-authentication and re-issue procedures of the license and continually to protect the rights of contents on the offline, we propose the DRM system that creates domain between home devices and enable users to freely transfer contents with the domain.

Despite the growing educational demand for the extended reality (XR) convergence content creation for non-IT students, fewer studies have attempted to education material development. In this paper, non-IT students' requirement to create XR convergence contents was analyzed and designed framework system specification. The object-oriented application framework (OOAF) was developed for non-IT students to create XR convergence contents through simple interaction methods such as drag and drop in-game engines. To evaluate the developed framework XR contents development course was operated with 26 industrial design majors sophomore in university. More than 90% of students succeeded in working on prototype XR contents in Oculus Rift. This result will be expected to improve the quality of XR contents creation education for non-IT students and contribute to the growth of the future convergence contents industry.

The purpose of this study is to investigate how the service quality of dance performance halls influences the satisfaction with performance halls and willingness of re-spectating. To perform this study, questionnaires were used and frequent analysis, factor analysis, correlation analysis, multiple regression analysis were used to analyze the collected data. Conclusions are as follows; First, the service quality of dance performance halls had an effect on the satisfaction of dance performance halls. Second, the service quality of dance performance halls had an effect on re-spectating. Third, the satisfaction with performance halls influenced the re-spectating. These results show that the higher the service quality becomes the more positive effect appears between the satisfaction of performance halls and re-spectating.

With the development of digital satellite communication technology and the widespread use of smart devices, the demand for data communication in the maritime ship has increased. Recently, the communication between the maritime ship and the land is based on Inmarsat satellite service. The Inmarsat provides telephone, fax, data and telex service etc. However, since the satellite is payper-seconds billing service, the transmission of whole web contents to the maritime ship through the satellite causes high cost. In this paper, we propose web browsing system architecture that reduces the data traffic on the satellite link and retransmits the content selectively in order to solve these problems.

지난 10월 문화재청과 KBS, LG전자가 공동으로 기획한 '다시 만난 우리문화 유산전'은 국외문화재를 울트라HD 영상으로 촬영하여 고화질의 디스플레이를 통해 국민들에게 국외의 문화재를 소개하였다. 국외문화재를 만으로 구성된 전시는 국민들에게 지금까지 볼 수 없었던 유물에 대한 정보와 이미지를 제공하여 국외 문화재에 대한 국민들의 관심을 이끌어 냈다. 하지만 관람 방법과 정보 전달적인 측면에서 한계가 있었다. 따라서 '다시 만난 우리 문화 유산전'의 사례를 살펴보고 관람 방법과 정보전달의 방법에 대한 보완점을 찾아야 한다. 앞선 전시에 대한 보완점을 전시에 적용한다면 국외에 있는 우리 문화재에 대한 지속적인 관심과 접근성을 높여 국외문화재에 대한 꾸준한 전시를 유도할 수 있을 것이다 또한 국외문화재를 학술적으로 폭 넓게 사용되어 활발한 연구가 진행되고 전시뿐만 아니라 다른 분야로의 확장을 이끌 수 있다.

There is no guideline or standard for the specification of the open-source-framework-based Spring AOP, and it causes confusion in development and maintenance. Moreover, the inconsistency between the existing MVC model, the AOP model that is used for Struts framework and the UML diagram makes the aspect reuse more difficult. In this study, a widened existing method was proposed so that Aspect, Pointcut and Advice could be expressed by either UML or XML to ensure that the Spring AOP can accept the combined use of the existing MVC model and the AOP model, which is used for Struts framework. Relationship was defined so that the mutual conversion could be possible with the proposed expression method, and the realization of simple development and maintenance was verified via the examples of mutual conversion. In addition, a packaging method to efficiently reuse aspect was proposed, and the possibility of reuse was verified.

Many researches have achieved to reuse existent experience at each step of software life cycle. It is achieved various study about Design Pattern serving that abstract level solves design problem at high level. But, design step is not supplying design information that is abstracted so that new designers may reuse standardizing defined good design information. Therefore, in this paper, to do so that can reuse existent design information because composes Design Pattern can solve problem at design step, and extend design information that also is standardized XMI to base meta model of Design Pattern. And I did so that can compose Design Pattern utilizing MetaModel of Design Pattern standardized by XMI. Therefore, software designer can reuse composing existent design information that is could standardize problem at design because uses MetaData of standardized Design Pattern, and designs by Design Pattern base.

The server redirection system replicates contents on replica servers in the distributed network environment. When users make a request for contents, the system can provide the contents much faster than the client-server network system. In the server redirection system, it is the most important to select the optimal replica server with user's information because many replica servers are geographically distributed. And, the system can serve contents to users flexibly if a redirector is well constructed. In this paper, the redirector makes a list of candidates suitable for user conditions by the decision tree method and calculates the availability of each replica server. And, the redirector selects the replica server with the highest availability. This paper also proposes an availability-based server redirection system that predicts the availability of each replica server in order to reduce the workload of replica servers and the repetitive communication messages between a redirector and replica servers. If a user accesses the network path for the replica server selected and noticed by the proposed system, the user can get contents effectively and efficiently.

온라인상의 쇼핑에서 사용후기에 관한 많은 연구가 진행 중이지만, 사용후기를 보는 원인에 관한 분석에 대해서는 아직 부족함으로 연구를 진행하였다. 온라인상이기 때문에 가지는 위험 중에서도 사용후기를 통해서 어떤 위험을 가장 많이 가지고 있는지에 대해 우선 알아볼 필요성이 있을 것 같다. 이의 연구결과 기능적 위험을 가장 크게 지각하고 있었기 때문에 사용후기를 보는 이유로서의 근거가 될 수 있을 것이다. 둘째, 의류에 관련된 논문들을 보면 온라인상에서 구매를 꺼려하는 이유가 직접 눈으로 보고 만질 수 없다는 기능적 위험을 가장 크게 가지고 있었다. 그렇기 때문에 대리 시용구매를 할 수 있는 사용후기를 이용하여 의류제품을 온라인상에서 구매하는 것이 영향을 미치는 것인지에 대해 알아보고자 한다. 본 연구 결과, 긍정적인 후기를 보고 구매하려는 의도가 나타났었고 부정적인 후기를 보고 구매하지 않으려하므로 사용후기가 구매함에 있어 영향을 미치고 있음을 알 수 있었다. 마지막으로 사용후기를 중심으로 메시지를 보고 메시지에 대한 태도와 제품에 대한 태도, 그리고 구매의도 뿐만 아니라 메시지의 유형에 따라서 구전 의도나 사이트 재방문 의도라는 구매 행동에도 차이가 날 것이라고 추측했다. 연구 결과를 보면 유형별로 각각 다르게 영향을 미치고 있었으며, 부정적인 메시지로 인해 제품에 대한 좋지 않은 태도를 가지게 됨으로써 제품을 구입하려는 사이트 재방문 의도는 나타나지 않았다.
