The purpose of this study is to analyze the process of changes in regional science and technology policies in Korea and to seek future development directions. In Korea, regional science and technology policies have been implemented since the introduction of the local autonomy system. Since then, it has been implemented in earnest with the establishment of a central government-level plan. The regional science and technology policies have been developed to this day by interacting with national science and technology policies and regional development policies. Nevertheless, due to the path dependence and lock-in effect in the accumulated process, the regional science and technology policies are still subordinate to central government policies. Thus, the establishment of an independent ecosystem for local science and technology is still insufficient. Furthermore, the gap between regions is deepening, such as the growing of aging population, population decline due to low birth rates, job losses due to the recession of local key industry, and the concentration of the youth population in the metropolitan area. The transformation path such as digital transformation and carbon neutrality paradigm is expected to further widen regional disparities. In order to address a comprehensive problem, the implementing system of regional science and technology policies need to be newly established. A framework for reinvention of regional science and technology policy needed in the era of grand societal challenges have to be developed.

Drawing on the autonomist Marxist concepts of 'social factory', 'immaterial labour', and 'precarity', this paper discusses the changed nature of labour, life and social relations in contemporary informational capitalism. More specifically, it first traces back to the early autonomist (operasimo) theories of 'social factory' and 'class composition' and then discusses how these earlier theories were developed into the concept of 'immaterial labour' by a group of later autonomist theorists such as Paolo Virno, Maurizio Lazzarato, Micheal Hardt, and Antonio Negri. Then, it reviews how the concept of immaterial labour was taken up to understand the nature of labour in digital economy within the tradition of Cultural Studies, closely intersecting with the critiques of 'creative labour'. Finally, it discusses how the changed nature of labour is interrelated with the neoliberal labour forces transformations such as casualization of employment and increasing insecurity in employment and life, which the autonomist explores with the concept of 'precarity', the material condition of immaterial labour.

In the future there would be many kinds of digital images for many industrial markets. 3D stereoscopic images for variable fields; medical operation, film and animation, broadcasting, internet, game, or design for art and architecture. And many people to work about computer programming, and digital image making will concern about it more and more. However, these kinds works and studies are focused on the professional technical fields like 3D display or computer programming technology so far. To revitalize the market of a variable stereoscopic contents, there should build up the foundation for easy processing of the making stereoscopic images. This paper is based on stereoscopic making skills for anaglyph system. An anaglyph system has an old history about making stereoscopic images, and very simple method to produce the stereoscopic images. Particularly this study is focused on color compositing technique, and camera positioning on the compositing system. It will help optimization of the environments to create 3D motion graphic and animation contents.

For Effective and systematic response to disasters, needs of broadband multimedia services in wireless communication of PPDR(public protection and disaster relief) is increasing gradually. Recently in Korea, by the digital television transition, Korea Communications Commission is considering whether the freed spectrum can assign additional spectrum of PPDR or not. In this paper, we were defined the input parameters, were estimated the spectrum of requirements for Korean wireless communication of PPDR based on M.1390 methodology recommended by ITU-R.

최근 스마트 시대에 디지털 컨버젼스(digital convergence)의 대표기기로 대두되고 있는 태블릿 PC는 휴대전화와 컴퓨터의 기능을 바탕으로 장소의 제한 없이 네트워크에 접속할 수 있다. 이는, 개인의 일상생활에서 큰 영향을 미치고 있는 실정이다. 10년 이상 e러닝이 주도해 온 IT교육시장에서 스마트러닝으로의 변화는 새로운 플랫폼을 구축하는 그 이상의 의미를 가진다. 스마트 러닝은 기존의 수직적인 학습방식을 수평적, 참여적, 지능적, 그리고 상호작용적인 방식으로 전환하여 학습의 효과를 높였다. 이러한 트랜드를 반영하여 스마트러닝의 장점을 극대화 시킬 수 있는 학습자 중심의 컨버젼스 러닝시스템(learning system)을 구현하고자 하였다. 또한, 영어의 중요성이 대두되면서 영어 인증시험에 대한 관심이 날로 커지고 있다. 그리하여 바쁜 일상생활 중에서 시간과 장소에 구애 받지 않고 태블릿 PC를 통하여 영어 인증시험을 공부할 수 있는 어플리케이션을 기획하였다. 본 LEMON(Learn English Mobile ON-air) 앱(application)은 영어 학습 시간이 충분하지 않은 대학생 및 직장인 등을 대상으로 TOEIC, TOEFL, TOEIC SPEAKING 영어 인증시험에 대한 학습이 가능하도록 구현하였다.

2020년 전자서명법 개정으로 공인인증서가 폐지됨에 따라 자체 인증 기술의 도입이 필요한 실정이다. 특히나 COVID-19로 인한 비대면 상황이 지속됨에 따라 기존 아날로그 방식을 통해 대면으로 계약서를 작성하고 수립하는데 많은 비효율적 문제가 대두되었다. 디지털 전환 가속화와 비대면 거래확대로 인한 전자 신원확인 중요성이 점차 커지고 있음에 따라 전자 서명 및 전자 봉투 방식으로 계약할 수 있는 안전한 시스템 개발을 진행하고자 한다. 이를 위해 계약 시스템의 보안 요구 사항을 도출하였으며 최종적으로 NFT 연동을 통해 안전한 계약을 진행할 수 있도록 프로세스를 설계하였다. 시스템의 동작 방식을 표현하기 위하여 DFD 등을 포함한 Diagram 형태로 나타내었으며 실제 프로토타입을 제작 후 블록체인 네트워크에 연결한 뒤 테스트를 진행하여 시스템 검증을 수행하였다. 추후 이 시스템을 통해 B2B, B2C 모델 등의 모델 기반 다양한 거래와 계약이 가능하도록 구성할 예정이며 추가적인 연구를 진행하여 사용자 측면에서 더 간편하고 안전한 환경이 될 수 있도록 고도화 시키는 것을 목표로 한다.

The level of transference of NGN is beginning as the operation of Access Gateway in korea at present, but NGN will keep developing continuously to the NGN integrated network until 2010. This research is finding the meaning and assignment of NGN QoS to deduct how to manage the control system and presenting the QoS control process and trial framework. The trial framework is the modeling of the QoS measurement metrics, the measurement time schedule, the section, hierarchy, instrument, equipment and method of measurement and the series of cycle & the methodology about analysis of the result of measurement. The objective standard of quality in communication service is guaranteed not by itself but by controlling and measuring continuously. Especially it's very important time to maintain the research about NGN QoS measurement and control because the big conversion of new network technology paradigm is now spreading.

Human desires start from the factors that make up the basic living environment. The development model of the safety guidelines will start from a sense of departure from collective psychology and systemic environment, at the time of inducing threats to threats. The design and methodology of the safety guidelines should be drawn up repeatedly by the sequence of iterative models, and the design methodology should be designed in the chronological order of the public services through the methodology of service design methodology. Various and complex threats attempt to derive insights from the user's perspective and to derive insight into the development of the safety guidelines and the sophistication of the user experience, and to extract insights from the perspective of a user's perspective and supervision model. This derived insight can be implemented as a multi-dimensional service model derived from the same problem consciousness methodology.
