  • With the advent of the Information Age, the source identification of digital images, as a part of digital image forensics, has attracted increasing attention. Therefore, an effective technique to identify the source of digital images is urgently needed at this stage. In this paper, first, we study and implement some previous work on image source identification based on sensor pattern noise, such as the Lukas method, principal component analysis method and the random subspace method. Second, to extract a purer sensor pattern noise, we propose a sample selection method to improve the random subspace method. By analyzing the image texture feature, we select a patch with less complexity to extract more reliable sensor pattern noise, which improves the accuracy of identification. Finally, experiment results reveal that the proposed sample selection method can extract a purer sensor pattern noise, which further improves the accuracy of image source identification. At the same time, this approach is less complicated than the deep learning models and is close to the most advanced performance.

  • The advent of digitalisation has transformed economies into more integrated, but increasingly complex systems. This new trend has brought dynamic changes in the manufacturing sector through advanced ICT infrastructure, smart factories, digitally-controlled logistics, and skilled ICT-labour. The impacts of the digital economy on manufacturing could be best illustrated through "Industry 4.0." With this wave of technological advancement, countries aim to establish an industrial ecosystem where every manufacturing process and function is connected and interacts through digital networks. Industry 4.0 presents opportunities for Emerging Asia, as the region has emerged as a fast-growing manufacturing hub and particularly a production base for ICT goods. However, growing production capacity, increased exports, and increases in FDI in the field of ICT goods manufacturing have so far contributed little to the development and diffusion of ICT. A huge gap exists in the ICT uptake amongst countries and between small and large firms. This paper highlights the level of Industry 4.0 readiness of Emerging Asia and key factors that determine its enhancement.

  • 공유경제의 등장은 디지털 기술을 사회혁신에 활용하는, 디지털 사회혁신을 사회문제의 새로운 해결책으로 주목 받게 하고 있다. 그런데 또 한편으로는 부스러기 공유경제, 주문경제처럼 디지털 기술의 부정적 영향을 우려하는 목소리도 있다. 본 연구는 디지털 사회혁신에 의해 창출되는 가치의 성격과 원천 그리고 작동방식을 밝힘으로써 제기된 의문과 우려에 대한 답을 구해보고자 한다. 먼저 사회혁신이 창출하는 비즈니스 가치의 성격과 원천에 대해 논의하고 디지털 기술에 의해서 창출되는 비즈니스 가치의 성격과 원천을 검토한다. 기부, 연대, 공유라는 사회혁신 활동 창출 가치의 원천, 그리고 디지털 기술이 만들어내는 가치의 원천인 효율성과 효과성을 알아보고 소비자/사용자의 역할을 논의한다. 실제 디지털 사회혁신 성공사례인 행복주차골목 리빙랩의 비즈니스 모델 분석을 통해 창출되는 가치들이 실제 현장에서 어떤 방식으로 발생하고 구현되는지 알아본다.

  • This study analyzed the efficiency and influence factors according to the main research institute type of R&D Program for the local community problem-solving. This study applied data envelopment analysis (DEA) method and Tobit regression analysis by using 20 institutions that participated in R&D Program. The results are summarized as follows. First, Analysis results according to the research institute type of R&D project, Efficient DMUs showed more regional innovation institutions than social economy enterprises. But regional innovation institutions were the lowest in the CCR and BCC model. However, efficiency dose not differ between regional innovation institutions and social economy enterprises. Second, as a result of the analysis relation between efficiency and allocation characteristics of R&D input, the participation of regional innovation organizations as participating organizations has a negative effect on efficiency. It was found that the higher the proportion of government subsidies and the higher the employment rate of the vulnerable, which is a social achievement, the positive effect on efficiency. The implication of this study is that the participation of social economy enterprises as the main R&D institution and government R&D support can provide social economy enterprises with opportunities to accumulate R&D capabilities and experience successful commercialization.

  • 최근 디지털 플랫폼을 활용하여, 사회·경제활동을 수행하는 시니어들이 증가하고 있다. 이들은 디지털 플랫폼을 통하여 새로운 사회적 네트워크를 구축하거나, 수익을 창출하는 등 새로운 정체성을 형성하고 있다. 해당 플랫폼에 참여하는 시니어들이 점차 증가추세임에도 불구하고, 아직 이와 관련된 학술적 논의는 아직 미미한 상황이다. 이에, 본 연구는 디지털 플랫폼에서 사회·경제활동을 하는 시니어 17명을 대상으로, 심층 인터뷰(in-depth interview)를 수행하여, 그들의 참여 동기와 경험을 세밀히 살펴보고자 하였다. 본 연구의 결과는 향후 디지털 플랫폼을 매개로 그들의 사회적 고립을 예방하고, 나아가 그들을 향후 디지털 경제의 주체로 유도하는 데 있어 기반 자료로 활용될 수 있을 것으로 예측된다.

  • Entering the 21st century, the primary influence leading world economy have been shifting. U.S. economy has seemed to slow down, Japan and EU are also in same situation. But China have started to lead Asia economy and expended to the World. According to Goldman Sachs Group, "The 21st century will be a era of Brics because of their enormous territory, a large population and abundant natural resources." We have to more focus on China because China have directly effect on Korean market and have a great potential market opportunity for our industries. However, this report mentioned above didn't carefully deal with a field of information and technology(from here IT), Digital contents consumption wasn't mentioned at all. Now Digital Contents (from here 'DC') emerge as new value creator and actually Korea has been a dominant in IT industries and is leading Digital contents market in China. This phenomenon is called as 'Korean wave (Han-Ryu)'. Many researchers have studied about 'Korean wave(Han-Ryu)' focusing on the economic effect but Korean DC industries need to build specifical strategies for exporting Korean DC to China market. Therefore, purpose of this study is following : Firstly, to analyze environment of DC in China and competitive advantages of it. Secondly, to compare ICAI (Industrial Comparative Advantage Index) according to a kind of DC. Finally, to make an analysis of China consumer's attitude to DC. This study will give much implication for Korean DC industries to enter China market.
