The purpose of this study is to suggest 100MPa class ultra high strength concrete mix design model applying neural network theory, in order to minimize an effort wasted by trials and errors method until now. Mix design model was applied to each of the 70 data using binary binder, ternary binder and quaternary binder. Then being repeatedly applied to back-propagation algorithm in neural network model, optimized connection weight was gained. The completed mix design model was proved, by analyzing and comparing to value predicted from mix design model and value measured from actual compressive strength test. According to the results of this study, more accurate value could be gained through the mix design model, if error rate decreases with the test condition and environment. Also if content of water and binder, slump flow, and air content of concrete apply to mix design model, more accurate and resonable mix design could be gained.

모바일 게임 콘텐트 제작과 서비스 기술 수준의 향상은 모바일 게임 시장의 폭발적인 증가를 가져오고 있다. 현재 서비스 되고 있는 모바일 게임은 WAP 방식과 다운로드 방식을 사용하고 있다. 기존에 구현된 모바일 게임 콘텐트는 구현과정의 기술적인 문제로 인해 WAP->다운로드, 다운로드->WAP으로 이어지는 연동 콘텐트를 구현할 수 없었다. 본 연구에서는 WAP->다운로드, 다운로드->WAP로 이어지는 무무선 연동을 혼합적으로 사용한 모바일 게임 콘텐트를 설계하고 구현하였다. 제안 방식은 WAP게임과 다운로드 게임 간에 실시간으로 연동 자료를 공유함으로써 기존의 게임 콘텐트가 가질 수 없었던 랭킹과 스테이지의 연동이 가능하게 하였다.

It is required for today's video contents to interact with a viewer in order to provide more personalized experience to viewer(s) than before. In order to do so by providing friendly experience to a viewer from video contents' systemic perspective, understanding and analyzing the situation of the viewer have to be preferentially considered. For this purpose, it is effective to analyze the situation of a viewer by understanding the state of the viewer based on the viewer' s behavior(s) in the process of watching the video contents, and classifying the behavior(s) into the viewer's emotion and state during the flow. The term 'Flow-emotion-state' presented in this study is the state of the viewer to be assumed based on the emotions that occur subsequently in relation to the target video content in a situation which the viewer of the video content is already engaged in the viewing behavior. This Flow-emotion-state of a viewer can be expected to be utilized to identify characteristics of the viewer's Flow-situation by observing and analyzing the gesture and the facial expression that serve as the input modality of the viewer to the video content.

IP 셋톱박스에 서비스되는 콘텐츠는 IP 네트워크를 통하여 전송되므로 네트워크 해킹 도구를 이용하면 스트리밍되는 콘텐츠를 저장후 불법이용이 가능하다. 따라서 안전한 스트리밍 서비스를 위해서는 스트리밍 환경에 적합한 콘텐츠 보호 방법이 요구된다. 최근까지 스트리밍 서비스되는 콘텐츠는 MPEG-2 TS를 이용하였지만, 낮은 압축률과 TS 패킷의 높은 오버헤드때문에 현재는 WMV, MPEG-4, H.264로 점차 옮겨가고 있다. 본 논문은 스트리밍되는 윈도우 미디어 콘텐츠를 보호하기 위한 DRM을 제안한다. 제안하는 방법은 기존의 WMV 스트리밍 시스템에 비의존적으로 설계되어 기존의 스트리밍 환경에 적용이 용이하고, 사용자 기기의 성능을 고려하여 DRM 처리 시간을 조절할 수 있도록 선택적 암호화 기법을 제공한다. 본 논문에서는 실험을 통하여 선택적 암호화를 이용하여 DRM 처리시간을 감소시킬 수 있음을 보인다.

반려동물 산업이 급성장함에 따라 반려견을 위한 디지털 콘텐츠까지 그 영역을 넓히고 있다. 이에, 본 연구는 반려견의 감각적 특성인 시각적, 청각적, 후각적 요소를 고려해, 반려견 콘텐츠에 적용 가능한 게임 요소를 제시하고자 한다. 이를 위해 먼저, 반려견주에게 지속적인 콘텐츠 사용을 유도하기 위한 요소로 출석과 규칙을 도출하였고, 반려견이 콘텐츠를 통해 재미와 흥미를 느껴 긍정적인 반응 얻을 수 있도록, 친밀도와 보상을 게임화 요소로 도출하였다. 본 연구를 통해, 새롭게 진화하는 반려견 콘텐츠 산업에 활력을 불어넣을 것으로 기대한다.

Korea's cultural content industry can develop into another unique tourism industry. However, since other prior studies focus on the Japanese content industry, this study identifies modern industrial trends by combining the unique characteristics of Korean content, that is, cultural content tourism, and the analysis ability of big data. The current status and direction of the cultural content tourism industry were studied by utilizing the extensive information collection and in-depth analysis capabilities of big data, and as a result, it was confirmed that the trend of the cultural content industry is related to the business aspect of cultural content, not the pure content interest of cultural content. This shows that Korean cultural contents have a strong business aspect. As a limitation, when research design was conducted using social media big data, the age, gender, etc. of the subject analyzed with unique anonymity could not be known. The Korean cultural content industry is expected to be successful in terms of business.

무선 인터넷 시장이 급속히 성장함에 따라 모바일 콘텐츠에 대한 수요가 급증하고 있다. 사용자에게 서비스되고 있는 모바일 콘텐츠는 텍스트나 음성과 같은 단일 미디어 콘텐츠에서 멀티미디어 콘텐츠로 변화하고 있다. 향후 이동전화와 광대역 통신 기술이 발전함에 따라 개인의 개성을 보다 잘 표현할 수 있는 멀티미디어 콘텐츠 개발이 더욱 활발해 질 것이다. 이러한 콘텐츠 발전의 한 예로 통화연결음 콘텐츠 서비스를 들 수 있다. 통화연결음 콘텐츠 서비스는 기존의 단순한 통화연결음에서 개인의 취향에 따라 다양한 음악으로 변경해주는 서비스로 발전하였다. 본 논문에서는 차세대 모바일 콘텐츠 서비스를 위한 멀티미디어 인사말 시스템을 설계하고 구현한다. 제안하는 시스템은 통화연결음 콘텐츠 서비스를 발전시켜 개인의 개성을 나타낼 수 있도록 다양한 멀티미디어 콘텐츠를 이용하여 직접 멀티미디어 인사말을 제작한다.

In this study, we showed understanding and production ability of the interface about internet, operating system, contents, and devices. This study aimed to make a list of 18 items in 4 areas for basic knowledge of UI/UX, establishment of design research, design concept, and design production for 22 sophomore, junior and senior students in IT departments, and the results of understanding were divided into three groups of excellent, normal, and insufficient, and evaluated. It was found that excellent was 18.39%, average was 38.52% and insufficient was 43.07%. Therefore, 18.39% of the students understood UI/UX, and 81.61% of students did not understand UI/UX well. In particular, in the comparison analysis of four areas, the design research area was 44 points, the design content area was 29 points, and the design production area was 11 points which was found to be the lowest. Next, the 10 evaluation items in the mobile UI/UX build guide evaluation were evaluated in the same way as the UI/UX understanding, and the excellent score was 3 points, the average score was 73.3 points, and the poor score was 155 points. The UI/UX build guides showed worse evaluation than UI/UX understanding. Therefore, to cultivate UI/UX understanding and content production ability, UI/UX experts should be fostered with professional course organization and systematic curriculum.

Purpose: The importance of creativity has been emphasized in the transition from industrial society to knowledge-based society. Recently, design thinking has attracted great attention as one of the ways to increase the creativity of the organization. From the perspective of solving urban problems through collaboration between technology and citizens, the active participation of citizens is indispensable for realizing smart cities. Research design, data and methodology: From the perspective of solving urban problems through collaboration between technology and citizens, the active participation of citizens is indispensable for realizing smart cities. Results: Therefore, the purpose of this research was to design a citizen-participation type system and contents using a specific space to realize a smart city. This system utilizes the concept of space as a tool to promote innovation activities with the participation of citizens and makes it easy for users of space to participate based on urban problems derived from living labs and the internal structure and user flow line have been designed. Conclusions: It was been also used voice recognition, artificial intelligence, the Internet of Things, and big data as important technologies for experiencing smart cities. The system and content were designed with an emphasis on allowing citizens to directly recognize and experience smart city technology, especially through space-based information visualization and multi-faceted stimulus elements.
