4차 산업혁명은 정보통신기술(ICT)의 발전으로 인한 다양한 산업분야의 혁명적 변화를 말한다. 이러한 변화는 한 기술자체의 발전뿐만 아니라 기술 간 융합과 연결을 통해 더 가속화될 수 있다. 학술적 영역에서도 ICT의 발전과 함께 디지털화에 소요되는 비용이 줄어들어 디지털화를 기반으로 한 학술논문의 공개, 공유의 움직임이 시작되었다. 학술논문의 공개와 공유는 기술 간 융합과 연결이 원동력이 되는 4차 산업혁명 시기에 더 중요하고 필요한 일이 되었다. 따라서 한 편의 학술논문이 가지는 고유의 가치와 수집된 논문이 집합체로서 활용을 통해 실현될 수 있는 잠재적 가치에 대해 알아보고자한다. 학술논문의 가치에 대한 평가를 통해 4차 산업혁명 시대를 더 잘 준비하기 위한 일환으로 학술논문의 가치 제고 방안에 대한 논의와 실행이 필요하다.

Pose estimation of the sensor is important issue in many applications such as robotics, navigation, tracking, and Augmented Reality. This paper proposes visual-inertial integration system appropriate for dynamically moving condition of the sensor. The orientation estimated from Inertial Measurement Unit (IMU) sensor is used to calculate the essential matrix based on the intrinsic parameters of the camera. Using the epipolar geometry, the outliers of the feature point matching are eliminated in the image sequences. The pose of the sensor can be obtained from the feature point matching. The use of IMU sensor can help initially eliminate erroneous point matches in the image of dynamic scene. After the outliers are removed from the feature points, these selected feature points matching relations are used to calculate the precise fundamental matrix. Finally, with the feature point matching relation, the pose of the sensor is estimated. The proposed procedure was implemented and tested, comparing with the existing methods. Experimental results have shown the effectiveness of the technique proposed in this paper.

본 연구에서는 음악 데이터 베이스에서 노래의 특정 구간과 가장 유사한 구간을 검색하는 시스템을 제안한다. 제안된 시스템에서는 음악을 다차원 시계열 데이터로 간주하고, 음악의 조성 차이 및 템포(tempo) 차이를 고려한 음악의 유사도 계산 방법을 사용한다. 유사도 계산의 전처리 단계에서 조성 차이를 보정하고, 비트(beat)를 검출하며, 추출된 크로마그램(chromagram)을 검출된 비트와 동기화 하여 평균한다. 이후, 동적 시간 왜곡(DTW; dynamic time warping)을 사용하여 두 구간사이의 유사도를 계산한 후 계산된 유사도 순서로 정렬된 검색 결과를 출력한다. 사용자는 제안된 시스템을 사용하여 선택 구간 유사도 검색과 자동 유사 검색 결과로 도출된 구간 쌍을 검토하여 유사 구간을 보다 쉽게 찾을 수 있다.

Is caused by with growth etc. of the digital contents circulation market which leads suddenly accommodates in order to control the network traffic which increases and the researches which are various are being advanced the explosive evidence and a electronic transaction of the Internet user. The present paper protects a digital contents and a copyright from CDN system environments which will appear the center of new network service with the plan for the dispersive DRM system of CDN bases plans. Respect this dispersion DRM package formats which provide a stronger security characteristic in the contents which is stored the operational process of the dispersive DRM system for to be defined, CDN system and of existing interoperability they present.

In this paper, broadcasting contents management system which is for sharing user-created information in restricted areas is proposed. By the proposed system, the information is compulsively sent to a television set receiving broadcasting contents via various transmit media. So, user should be contacting the information while they are watching broadcasting contents.

Due to the development of science and technology and the emergence of new industries, the environmental change of the digital contents industry is rapidly progressing. The scope of technological development in the digital contents industry is affecting not only the entertainment industry but also various industries. Recently, with the development of digital convergence using realistic content, games, video, and VR have provided new opportunities for the growth of the content industry. The researcher determined that a new education system would need to be changed as the digital contents industry developed. For this purpose, an AHP questionnaire was conducted for experts with a high basic understanding of the education platform based on previous studies. We proposed a platform model for human resource development as an education system that meets the demand of digital contents industry. The education system for nurturing talents needed by future society should include elements that can interest the learning of users. The platform should not be approached from a system point of view, but should be developed from the content and user's point of view, considering the platform's original purpose.

This study aims to analyze what is necessary for realization of convergence smart city service, and what is the priority order for it. First, the concept is set up through the theoretical review about convergence smart city service. Second, conduct in-depth interviews with smart-city related experts and derive the necessary elements to implement convergence smart city service. Third, derive priorities by subdividing the derived elements and utilizing the AHP method. The result of this study is expected to contribute to the development of convergence smart city service by deriving what should be considered for implementation of convergence smart city service.

The Journal of Digital Policy & Management. This space is for the abstract of your study in English. In this paper, we propose a u-convergence Tourist Information 3.0 System using Flow Theory. It generates a sense of u-challenge and u-skills to maximize the enjoyment of tourists is u-convergence Tourist Information 3.0. This is a challenge to good sense and adjust the rating of the Convergence Contents information quality(CCIQ) analysis to maximize the enjoyment of tourists. Convergence Contents information quality(CCIQ) of the conductive continuity of the content closed antecedents u-conductive sense, the tourist synchronization adequacy may generate data that can be analyzed. Content Information Quality of rating is the leading factor in the ability of the u-skill mastery of tourists, can generate data availability. The result is to create a meta-model is referred to as content information to reach the best quality maximize enjoyment. Design a sense of u-challenge the skill of the information quality of the tourist information content has the advantage of being able to identify the data formation has the pleasure of tourists. By applying to future national competent standard it is expected to maximize the enjoyment of the job.
