IT convergence plays a key role in increasing the value of goods and services in other industry sectors. The government has enhanced the policy and institutional support for convergence technology development and technology commercialization. Some of the leading companies already achieve performance through the strategic IT convergence. However, in order to maximize the benefits and performance of IT convergence, policies should be established from the viewpoint of industrial ecology and many companies can participate in and share benefits of IT convergence business. From an industrial ecology perspective, this study suggests a role of the government, keystone enterprise, and other stakeholder for promoting the IT convergence using analytic hierarchy process(AHP).

To have global competitiveness in newly growing industry, good quality R&D's in convergence technology arerequired. Korean government also started to emphasize the importance of convergence technology as a new engine of growth for the future development. Since 2008, worldwide energy crisis and concerns on low carbon green growth made people focus on the convergence between information technology (IT) and energy technology (ET). However, the R&D performance comparison among the convergence technologies is not well explored so far. Therefore, this study uses Korea's patent citation database to measure the R&D performance of convergence technologies. We adopt technology development cycle, technology spillover analysis, and technology diffusion analysis to see the knowledge flow from R&D industry to others. We find that IT_ET convergence technology generally shows higher R&D performance than other convergence technologies. Contrary to public belief, convergence R&D by big companies has relatively low performance especially measures in technology spillover and technology diffusion. This implies that they might concentrate on delicate Fuel Cell Energy/Environment Technology (FEIT) or Nano Environment/Energy Information Technology (NEIT) rather than general energy information technologies. We also find that Korea's chemical industry may play a crucial role for the growth of other convergence technologies.

We called a current society the convergence generation. In information society, digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. The effects of convergence technologies and social phenomenons are visualized in overall regions of society such as economy, society, culture, etc. In 2011, The Government introduced "IT Convergence Technology Prediction Survey 2025". This report includes 10 ICT industries. In this paper, we described a smart city which was leading case in digital convergence and related with our life.

Securing a well-trained workforce with skills and expertise is a prerequisite for the successful fostering of IT industry. Investment into human resources in a knowledge-based economy is more effective than material resources since a high quality IT workforce is recognized around the world as the key resource that decides the national competitiveness. This study examines the environments of IT industry that are ever-changing depending on technology trends such as new bases for IT technology and convergence, the concept of IT convergence. The concept and necessity of ideal talents of convergence are also addressed as the paradigm of IT industry is changing. Chapter 3 analyzes the governmental demand-oriented IT workforce training programs and supports for convergence IT workforce training centers conducted by the government as well as convergence workforce training programs. Chapter 4 analyzes, based on the survey, major factors that may affect the attempt to secure an efficient education system for convergence-oriented IT workforce training in reflection of corporate demands. Lastly, chapter 5 states the major findings and limitations of this study.

Many scholars have addressed the technological convergence of small-medium sized firms in Korea and their impact on the economic growth of nation. Nevertheless, most studies have been investigated the relationship between entrepreneurship and venture creation, and a few studies have analyzed the innovation and technological convergence of SMEs. The purpose of this research is to gain industrial insight into the technological convergence and to suggest a dynamic growth policy for entrepreneurs of SMEs to improve their convergence performance based on IT and BT. Therefore, we intend to propose solutions to these key questions in convergence such as; what are the key patterns in the process of technological convergence of SMEs on IT and BT, and what kinds of strategy do their need? In order to answer these research questions, we adopt network analysis using patent citation information. Results of network analysis revealed that building ecosystem based on government and universities is one of the most important factors for the future growth of SMEs in Korea. Also, the fit between technological convergence direction of SMEs and division of convergence structure of government and universities will be positively associated with dynamic growth of SMEs in Korea. In conclusion, this research extends the current studies on important aspects of SMEs in the technological convergence process by proposing their growth in convergence process to a newly converging context, IT and BT, and shed light on the integrative perspectives of crucial roles of SMEs on innovation performance in the IT and BT technological convergence.

대규모 양자컴퓨터의 개발은 현재 사용하는 많은 암호화 알고리즘에 위협이 될 것으로 예상한다. 현재 NIST 는 양자 후 시대에 대비하기 위해 양자 내성 암호를 표준화 하기 위한 작업을 진행하고 있으며 이에 따라 post-quantum 시스템의 마이그레이션 과정이 필요하며 각 시스템에 QSC 적용을 위한 연구들이 이어지고 있다. 본 논문에서는 양자 후 시대에 대비하기 위해 NIST 의 PQC post quantum conference 에서 발표한 PQC 후보와 QSC 마이그레이션 과정 및 적용 방안에 대해 조사한다.

IoT 기기가 발전으로 블루투스 활용도와 보안에 대한 관심이 증가하면서, 블루투스와 관련된 취약점이 매년 발생하고 있다. 보안을 높이기 위하여 블루투스 4.2 버전부터 페어링 단계에서 타원곡선 디피-헬먼 키 교환을 적용하였지만 타원곡선 기반의 암호들은 양자컴퓨터의 발전과 Shor 알고리즘에 의해 더 이상 안전하다고 보기 어렵다. 본 논문에서는 양자 환경에서 발생할 법한 블루투스 관련 취약점을 미연에 방지하기 위하여 페어링 단계에 적용된 기존의 암호 대신 양자 내성 암호 NewHope를 적용한 블루투스 모델을 제안한다.

In this letter, we present a design of a single chip video decoder called advanced mobile video ASIC (A-MoVa) for mobile multimedia applications. This chip uses a mixed hardware/software architecture to improve both its performance and its flexibility. We designed the chip using a partition between the hardware and software blocks, and developed the architecture of an H.264 decoder based on the system-on-a-chip (SoC) platform. This chip contains 290,000 logic gates, 670,000 memory gates, and its size is $7.5\;mm{\times}7.5\;mm$ (using 0.25 micron 4-layers metal CMOS technology).
