  • Digital transformation refers to the economic and social effects of digitisation and digitalisation. Although digital transformation acts as a useful tool for economic/social development and enhancing the convenience of life, it can have negative effects (misuse of personal information, ethical problems, deepening social gaps, etc.). The government is actively establishing policies to promote digital transformation to secure competitiveness and technological hegemony, however, understanding of digital transformation-related risk issues and implementing policies to prevent them are relatively slow. Thus, this study systematically identifies risk issues of the future society that can be caused by digital transformation based on quantitative analysis of media articles big data through the Embedded Topic Modeling method. Specifically, first, detailed issues of negative effects of digital transformation in major countries were identified. Then detailed issues of negative effects of artificial intelligence in major countries and Korea were identified. Further, by synthesizing the results, future direction of the government's digital transformation policies for responding the negative effects was proposed. The policy implications are as follows. First, since the negative effects of digital transformation does not only affect technological fields but also affect the overall society, such as national security, social issues, and fairness issues. Therefore, the government should not only promote the positive functions of digital transformation, but also prepare policies to counter the negative functions of digital transformation. Second, the detailed issues of future social risks of digital transformation appear differently depending on contexts, so the government should establish a policy to respond to the negative effects of digital transformation in consideration of the national and social context. Third, the government should set a major direction for responding negative effects of digital transformation to minimize confusion among stakeholders, and prepare effective policy measures.

  • Socially-oriented R&D programs aimed at solving societal problem rather than scientific and industrial fruits have started recently. Societal problem is recognized as dilemma since this problem related to various stakeholders. And this is not solved with single program and needed long-term process. So the perspective of socio-technical system transition including technological and institutional change is needed. This paper suggests policy implication of Socially-oriented R&D programs from socio-technical system transition perspective. 'Transitioning of Socially-oriented R&D program' is the key concept of restructuring the program for the system transition. The establishment of multi-layer transition governance and the transition vision-making and transition experiment planning are the key process of transitioning the R&D program. This paper suggests the ways and issues of implementing this process in Socially-oriented R&D program.

  • 장면 전환 검출(Scene Change Detction)수행 방법으로 객체 인식에 의한 검출이 아닌 전체 영상의 전역적인 형태 흐름을 기반으로 한 검출 시스템을 제안한다. 형태흐름의 변하는 영상의 전체적 모양에 관한 전역적 특징을 이용하여 영상내에 존재하는 에지, 에지의 중심, 표준 편차 및 에너지의 분포 변환에서 추출할 수 있다. 본 논문에서는 효율적인 에지 검출을 위하여 미디언 필터와 개량형 라플라시안 필터를 사용한다. 일반적으로 이용되는 라플라시안 필터를 사용하였을 때 획득할 수 있는 에지 정보보다 우수한 정보를 얻을 수 있었고 보다. 정착한 장면 전환을 검출하기 위해 이 에지 정보를 수평$(0^{\circ})$, 수직$(90^{\circ})$, 대각선$(45^{\circ},\;135^{\circ})$ 방향으로 세분화한 뒤에 프레임간에 각도 방향별 에지 정보를 파악하여 방향별 에지 에너지(Energy of edge)의 상대적인 성분 분포의 비교를 수행함으로써 정확성을 높였다.

  • In this paper, a new touch user interface which is based on the hand operations of dragging and diversion is presented. With it, convenience and quickness for inputting of texts as well as searching and selecting of multi-layered menus are improved. The new interface also applies relative coordinate systems which display texts on the touch positions corresponding to the moving of touch location. It accommodates more text codes than those in conventional fixed coordinate systems which allocates texts to fixed location on touch screen. The suggested interface is implemented to IPTV remote control and set-top box to prove its practicality and effectiveness.

  • It needs to consider of turns during a path-finding on real road network. Because a car is delayed by waiting a traffic signal and decreasing speed when drived in a turn road such as cross road and slip road. If a straightness of a path is increased, a real cost of traveling should be able to decrease. An older method, the algorithm with Turn Heuristic, considered of this case. The algorithm, that differently gave weights to left, right and U-turns, improved a straightness of a path, but increased a cost of exploring. In this paper, we propose a improved Turn Heuristic Algorithm. Proposed algorithm uses Dynamic Turn Heuristic. It is able to more decrease a cost of exploring than older method by using the Turn Heuristic in a part of path-finding.
