The increasing popularity of the concept of technology innovation has been driven by greater international competition in a rapidly globalizing economy. Both countries and enterprises are placing more and more emphasis on it in order to gain competitive advantages. This article gives a general introduction about the research and application of technology innovation in China. At the national level, one obvious fact is that the total R&D expenditure increased rapidly during the year 2001 to year 2005 and reached Y 245 billions, and China made 2,452 international patent applications in 2005 and became the world's 10th largest user of the Patent Cooperation Treaty. At the industry and enterprise level, much progress has also been made in China. This article uses the high-tech industry as an example to introduce the industry and enterprise technology innovation respectively. Corresponding to the practice, scholars also did a great amount of research work related to technology innovation. This article sums up all the work done from the macroscopic aspect (such as national technology innovation strategy, regional innovation system, industry technology innovation) and microcosmic aspect (such as enterprise technology innovation strategy, patterns and evaluation standards). Based on the analysis, this article discusses the limitation of current work and research trend about the technology innovation.

When the 60-ton-class patrol boat '72' of the Korea Coast Guard (KCG) was on duty and she accidentally collided with another patrol boat ('207', 200-ton-class) and sank. A month-long search found a small amount of lost items, but neither the crew nor the ship was found. For the first time in 39 years since the accident, the Korea Institute of Ocean Science and Technology (KIOST) searched the boat 72 using the latest integrated geophysical techniques. A number of sonar images presumed to be of a sunken ship was acquired using a combined system of side scan sonar and marine magnetometer, operated at an altitude of approximately 30 m from the seabed. At the same time, a strong magnetic anomaly (100 nT) was detected in one place, indicating the presence of an iron ship. A video survey using a remotely operated underwater vehicle (ROV) confirmed the presence of a shielding part of a personal firearm at the stern of the sunken vessel. Based on these comprehensive data, the sunken vessel discovered in this exploration was assumed to be '72'. This result is meaningful in terms of future ocean exploration and underwater archaeology, as the integrated system of various geophysical methods is an efficient means of identifying objects present in the water.

A novel smart metering technique capable of anomaly detection was proposed for real-time home power management system. Smart meter data generated in real-time were obtained from 900 households of single apartments. To detect outliers and missing values in smart meter data, a deep learning model, the autoencoder, consisting of a graph convolutional network and bidirectional long short-term memory network, was applied to the smart metering technique. Power management based on the smart metering technique was executed by multi-objective optimization in the presence of a battery storage system and an electric vehicle. The results of the power management employing the proposed smart metering technique indicate a reduction in electricity cost and amount of power supplied by the grid compared to the results of power management without anomaly detection.

The KSLV-II project with high difficulties technically requires thorough technical management during long-term life cycle more than 10 years for launching into space. The TRL is a quantitative indicator developed by NASA widely used all over the world to measure technology maturity of a system development objectively and consistently. The TRL is also used to make sure technology level and to establish a future direction in the KSLV-II project. The TRL has advantage enable to identify a technology level through quantitative indicators. However, it takes a lot of efforts such as trials and errors, time and cost to apply it to the project considering the project environments, and stakeholder needs. These include not only to establish TRL management plan from ideal, conceptual and abstractive standards/guidelines such as NASA's, but also to construct TRL management environment enable to apply and manage harmoniously. In the KSLV-II project, it is required to figure out current technology level and technology development trend in the future, to access conveniently, to share related data in real time, and to update periodically for the comprehensive TRL management. From the reason above, the TRL management environment was built by using the systems engineering tool already has been used for other system management data such as requirements in the project. It also could be accomplished a practical management basis of systems engineering from the traceability among system management data including TRL. In this paper, case study results are introduced to manage the TRL for the space launch vehicle using the systems engineering tool in the KSLV-II project.

Technological innovation generates products, services, and processes that can disrupt existing industries and lead to the emergence of new fields. Distributed ledger technology, or blockchain, offers novel transparency, security, and anonymity characteristics in transaction data that may disrupt existing industries. However, research attention has largely examined its application to finance. Less is known of any broader applications, particularly in Industry 4.0. This study investigates academic research publications on blockchain and predicts emerging industries using academia-industry dynamics. This study adopts latent Dirichlet allocation and dynamic topic models to analyze large text data with a high capacity for dimensionality reduction. Prior studies confirm that research contributes to technological innovation through spillover, including products, processes, and services. This study predicts emerging industries that will likely incorporate blockchain technology using insights from the knowledge structure of publications.

The purpose of this study is to identify trends and to analyze knowledge structure and knowledge flow of studies on science and technology policy adopting the keyword network analysis. For analysis, we established a data set of published papers in the Journal of Korea Technology Innovation Society and Journal of Technology Innovation from 1993 to 2016. As a result of analysis, a great part of existing researches have been carried out in Seoul and Daejeon area, universities and public research institute. So it should be carried out in diversified form rather than being concentrated on specific regions or research performing subjects in the future. By research scope, more than 70% of research were carried out in 'R&D management' and 'technology innovation'. In the future, more research must be carried out in 'public process of science and technology' and 'public management of science and technology'. On the other hand, we performed the keyword network analysis to identify the knowledge structure of studies on science and technology policy. As a result of analysis, it was clustered into 'public process of science and technology', 'public management of science and technology', 'R&D management' and 'technology innovation', So It has not been different from research scope proposed by Yi, Kim and Oh(2016). And also, in earlier stage, research topics were general such as researchers and R&D investment. But as time goes by, topics were more diversified and subdivided. Therefore, in future, the research scope of studies on science and technology policy should be further expanded in terms of 'public process of science and technology', 'public management of science and technology', 'R&D management' and 'technology innovation', and systematic knowledge structure should be formed.

There is a growing interest in convergence. National R & D is also providing various policies and institutional support to promote convergence research. Convergence research, however, does not clearly specify its characteristics at the academic and government levels. This research proceeds with the process of collecting, refining, analyzing, modeling, verifying and visualizing national R & D data through the National Science and Technology Information Service (NTIS). The method is to derive the convergence research characteristics and to derive through text mining, focusing on the unstructured information of national R & D project data. The study confirmed that there was a difference in perception between the definition of converged research and the research site. In order to improve this, the research suggested that convergence among research subjects, collaboration among research topics reflecting various backgrounds and characteristics of researchers, and analysis of characteristics of convergence research using information were suggested in the process of establishing convergence policy.
