인쇄전자는 RFID 나 유연 디스플레이 등의 전자회로나 소자를 인쇄방식으로 제작하는 공정이다. 특히 롤투롤과 같은 웹 이송방식 프린팅은 얇은 필름형태의 웹(Web)에 그라비아 인쇄나 고속 잉크젯과 같은 방법으로 이송중인 웹 상에 회로를 형성하는 공법이다. 이 공정은 생산단가가 저렴하고 고속생산이 가능하다는 이점이 있다. 다층구조를 가지는 회로나 디바이스를 생산할 때, 층과 층을 얼마나 정확하게 중첩시켜 인쇄하는가 하는 것은 인쇄된 전자회로의 집적도와 성능을 결정짓는 중요한 요소이다. 인쇄전자공법을 상용화하기 위해서 높은 중첩정밀도 구현이 선행되어야 한다. 본 연구에서는 롤투롤 인쇄방식에서 중첩정밀도의 향상을 위한 위치측정 시스템을 제안하고 신뢰성을 확인하였다. 또한 웹이 변형되었을 때의 측정 강인성도 실험적으로 확인하였다. Printed electronics is a technology used for forming electronic circuits or devices, and it is used in the manufacture of many products such as RFID tags, solar cells, and flexible display panels with a much lower cost than in the case of semiconductor process technology. Web-guide-type printing such as roll-to-roll printing is a method used to produce printed electronic devices in a large volume. To commercialize such products, highly precise alignment between printed layers is required. In this study, a highly precise alignment system is proposed, and some experimental results are compared with those obtained using a laser surface vibrometer to illustrate the reliability of the proposed system. The robustness of the proposed system to web deformation is also considered experimentally.

As technological development accelerates, regulatory authorities have to collect relevant information to address rapid and safe introduction of new drugs with advanced technology. In this study, we investigated the cases of selected high-income countries that took advantage of horizon scanning, a systematic information collection method, for their early response to new drugs and advanced technologies in health care settings. To this end, we reviewed the contents available at the website of the relevant institution, as well as the literature such as white reports and journal articles. The International Coalition of Medicine Regulatory Authorities (ICMRA) was engaged in activities to prevent overlapping work in each country and to harmonize of regulatory procedures. ICMRA's Horizon Scanning Project suggested specific methodologies through an analysis of global best practices, identified regulatory science areas to address emerging technologies, and provided policy options to promote market access of new medicines. The PharmaScan database, in which manufacturers directly input information, was operated and used for horizon scanning in the UK. Considering the implications obtained through case review of each country, horizon scanning will contribute to improving regulatory approval process and to enhancing early market access of new drugs in Korea.
