In this study we aim to identify the core technologies that play central roles along with the peripheral technologies that contribute to the technology convergence in digital healthcare. A total of 376 korean-patents related to healthcare were gathered from 2011 to 2020, and a topic modeling technique and a network analysis were conducted on the collected data. Six major topics were derived through the topic modeling procedure which are "data collection", "signal measurement", "health management", "data transmission", "diagnostic treatment", and "measurement device". Each of the six topics were analyzed to depict relations among technologies, specify the convergence characteristics, and identify the core-technology through centrality analysis. The study illustrates the present status of digital healthcare technology development and the technological convergence in South Korea and is anticipated to help establish policies to foster healthcare industry.

This study proposes to identify digital library services applying cutting-edge technologies, and attempt to investigate the applicability of these technologies and services to domestic libraries. To this end, we reviewed main research which discusses next generation digital libraries, and examined thoroughly main technologies which can be applied to future libraries. As a result, the core technologies, concepts, and tools of the next generation of digital library are: cloud services, space for infinite creating (makerspace), big data, augmented reality, context-aware technologies, Google-glass, a revolutionary display technology, open linked-content-offering method, and so on. Specific cases of libraries already utilizing these technologies are also discussed.

The industry has undergone a significant change over the last decade: digital business has become a strategy to survive; the extended enterprise is being implemented; parts are made where conditions are most favourable; non-core activities are out-sourced; advanced manufacturing systems and information technologies are introduced to improve manufacturing performance. Suppliers and distributors become part of the supply chain and they all comprise an integrated international co-operative network to provide manufactured goods and support services for a world market just in time, at low prices and with quality surpassing customers' expectations. In this paper, we review various state-of-the-art information technologies for the shipbuilding industry. The successful introduction and implementation of those technologies will be the key enabler for e-transformation in the shipbuilding industry.

The style of war in the $21^{st}$ century became digitalized cooperative union tactic, which relies heavily on the system providing real time information. Critical information is provided during the war from sensing to shooting. Therefore, epochal development in observation, reconnaissance (ISR), commanding (C4I) and precision strike (PGM) are necessary. Application of ubiquitous computing and network technologies in national defense is necessary for carrying out with various types of wars in the $21^{st}$ century. Therefore, the author wants to research core technology sector that can be developed and applied in preparation of ubiquitous national defense era. Also plans for applying recent u-Defense technology to the military sector had been suggested. Particularly, the author have suggested plans for utilizing combined future information technologies such as ad-hoc network, RFID for the logistic supply in construction of u-Defense system. By utilizing these information technologies, combat power and strategic capabilities of the military can be enhanced greatly.

The frequency range of a radio wave is from 3kHz to 300GHz, and radio technologies use this range to improve the quality of human lives. Radio technologies have entered a new phase of communication. The core infrastructure used as the basis for technologies leading the fourth industrial evolution, such as artificial intelligence, the Internet of Things, autonomous cars/drones, augmented reality, robots, and remote medical diagnoses, is the 5G network. The 5G network enables transmitting and receiving large amounts of data at very high speed. In particular, application technologies with artificial intelligence have been studied, including radar, wireless charging, electromagnetic devices and their effects on humans, EMI/EMC, and microwave imaging. In this study, we present a future radio technology that is needed to prepare for the upcoming industrial revolution and digital transformation.

This paper discussed the following. 1. After reaching the final phase of an oil-based society, a resource-saving and -recycling "Methane Energy-based Society" will come about because of limited natural resources. 2. Industrial Infrastructure Technologies which support the Methane Energy-based Society will cause a paradigm shift in the area of industrial, transportation and civilian sectors. 3. The Non-communication application technology of microwaves plays an important role as one of the core element technologies which comprise new industrial infrastructure technologies.

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.
