With the rapid development of the Fourth Industrial Revolution and digital transformation, scientific and technological innovation measures are being devised to overcome Korea's low-growth, high-cost structure. Accordingly, by examining the R&D investment evaluation system of R&D PIE (R&D Platform for Investment and Evaluation), which has been promoted by the Korean government in response to the Fourth Industrial Revolution, from the perspective of R&D transformation, this study aims to explore a new path for a sustainable national science and technology innovation system following digital transformation. In particular, from the perspective of R&D PIE, a MLP (Multi-level Perspective), which had been conducted as an abstract theoretical study, was attempted with specific cases and analysis for each of the three layers: niche, landscape, and regime. In conclusion, R&D PIE was intended to elevate the abstract R&D investment evaluation system to a platform that leads innovation in the digital space of the Fourth Industrial Revolution. In addition, it was confirmed that the R&D PIE could be replaced or enhanced as a platform for innovation in response to the Fourth Industrial Revolution, thereby providing an alternative to job creation and an escape from economic crisis.

We have developed a prototype super-high-definition (SHD) digital cinema distribution system that can store, transmit, and display eight-million-pixel motion pictures that have the image quality of a 35-mm film movie. The system contains a movie server, a real-time decoder, and an SHB projector. Using a Gigabit Ethernet link and TCP/IP, the server transmits JPEG2000 compressed motion picture data streams to the decoder at transmission speeds as high as 300 Mbps. The received data streams are decompressed by the decoder, and then projected onto a screen via the projector. By using an enlarged TCP window, multiple TCP streams, and a shaping function to control the data transmission quantity, we achieved real-time streaming of SHD movie data at about 300 Mbps between Chicago and Los Angeles, a distance of more than 3000 km. We also improved the decoder performance to show movies with Image qualities of 450 Mbps or higher. Since UDP is more suitable than TCP for fast long-distance streaming, we have developed an SHD digital cinema UDP relay system, in which UDP is used for transmission over a fast long-distance network. By using four pairs of server-side-proxy and decoder-side-proxy, 450-Mbps movie data streams could be transmitted.

This paper examined the leapfrogging of Korean Digital TV Industry in the midst of digital Revolution. Despite the lack of sufficient capability and core knowledge base, the Korean firms succeeded in the catching up forerunner firms in the Digital TV industry. The reasons of the success of Korean firms were as follows. Firstly, the Korean firms had some complementary asset, such as the experience of producing analog TV, and were able to develop the prototype digital TV given the accesses to the foreign knowledge via overseas R&D posts and acquisition of a foreign company. Secondly, the Korean firms were not locked in the analog technologies. As a follower, they had little sunk cost on the existing analog technologies. Thirdly, New mode of innovation, such as National R&D program for the development of HDTV and ASIC, were used as a tool for the mobilization of scarce knowledge base of digital technologies and the sharing the risks of development of path-breaking new technologies.

The purpose of this study is to explore conquest plans of the barrier and resistance in innovation management. In addition, this study is to describe the model of innovation resistance that reflects adoption process stages and identify the factors that drive the resistance of consumers and the barriers. Whenever organizations try to plan and implement some kind of innovation in organizations, they confront the resistance and barriers in many ways. By understanding innovation resistance and barrier, organizations can not only design better innovations but can develop strategies to reduce resistance and conquer the barriers. Thus they accelerate innovation. Also, these results indicate that people resist innovation strongly when it betrays their value, needs and beliefs or when they felt the pressure on self-conviction and mental risk, loss, and lack of knowledge. Understanding the factors that drive the innovation resistance and barrier has important implications for both theoretical development and managerial action.
