In the era of the Fourth Industrial Revolution, digital transformation, which means changes in all industrial structures, politics, economics and society as well as IT technology, is an important issue. It is difficult to know which research topic is being studied because digital transformation is being studied in various fields. Convergence research is possible because a research topic is studied in various fields such as computer science area and Decision science area. However, it is difficult to know the specific research status of the research topic. In this study, eight research topics were derived using the topic modeling technique of text mining for abstract of academic literature and the trend of each topic was analyzed. We also proposed to create a Topic-Word Proportions Table in the LDA based Topic modeling process to predict the topic of new literature. The results of this study are expected to contribute to advanced convergence research on topic of digital transformation. It is expected that the literature related to each research topic will be grasped and contribute to the design of a new convergence research.

Renewable energy generation cannot be consistently predicted or controlled. Therefore, it is currently not widely used in the electricity market, which requires dependable production. In this study, reliability- and variance-based controls of energy storage strategies are proposed to utilize renewable energy as a steady contributor to the electricity market. For reliability-based control, photovoltaic (PV) generation is assumed to be registered in the power generation plan. PV generation yields a reliable output using energy storage units to compensate for PV prediction errors. We also propose a runtime state-ofcharge management method for sustainable operations. With variance-based controls, changes in rapid power generation are limited through ramp rate control. This study introduces new reliability and variance indices as indicators for evaluating these strategies. The reliability index quantifies the degree to which the actual generation realizes the plan, and the variance index quantifies the degree of power change. The two strategies are verified based on simulations and experiments. The reliability index improved by 3.1 times on average over 21 days at a real power plant.

One of the core keywords in the fourth industrial revolution is convergence, and the convergence of the production, distribution, and consumption processes of services is particularly important. The convergence of user services is underway in various industrial fields including mobile communications, healthcare, mobility, artificial intelligence, etc. In order to offer these converged services efficiently, it is necessary to provide accurate user-centric location information, which can be obtained by employing the global navigation satellite system (GNSS). In addition, as we have entered the post-COVID era, the demand for various fields such as a healthcare, customized tourism services, and aviation services based on accurate location information is exploding. In this paper, we present the results of a case study on the current research trends of GNSS used in telemedicine services and AI & IoT fields, and also analyze these results.

Since the announcement of President Klaus Schwab's fourth industrial revolution at the World Economic Forum in Davos, Switzerland in January 2016, the fourth industrial revolution has emerged as a hot topic in our society. The United States, Japan, China, and Germany, which are major advanced nations, are preparing and implementing a strategy and system for responding to the Fourth Industrial Revolution, focusing on information and communication technology (ICT) and manufacturing convergence in response to the fourth industrial revolution era. Korea is announcing the expansion of financial support for R & D investment budget and related industries for major technology related to revolution. In this paper, we analyze the defense R & D project procedure of the Defense Improvement Project, which is responsible for the development of the defense weapon system, and present the development direction of the defense weapon system in accordance with the 4th world industrial revolution trend.

Recently, the attention to the $4^{th}$ Industrial Revolution has been increasing. In the $4^{th}$ Industrial Revolution era, the boundaries between physical space, digital space, and biological space are becoming blurred because of the active convergence between various fields. There are many issues about the $4^{th}$ Industrial Revolution such as artificial intelligence, Internet of things, big data, and cyber physical system. To cope with the $4^{th}$ Industrial Revolution, an accurate analysis and technology planning need to be undertaken from a broad point of view. However, there is little research on the analysis of the major issues about the 4th Industrial Revolution. Accordingly, this study aims to analyse these major issues. Data mining such as topic modelling method is used for this analysis. This study is expected to be helpful for the researcher and policy maker of the 4th Industrial Revolution.

산업스파이에 의한 핵심기술 유출이 점차 지능화, 첨단화, 복잡화 되어가고 있으며 이로 인한 피해 또한 심각해지고 있다. 이러한 상황에 대응하는 방안으로 융합보안이 대두되었고 모든 산업분야에 점차 확대되고 있다. 특히 국가적 핵심기술과 인력 및 시설을 포함하고 있는 방위산업은 융합보안이 더 요구되는 산업분야이다. 방위산업은 국가의 안전보장에 필요한 방위산업물자를 연구, 개발, 생산하는 산업이다. 방위산업은 군사기밀, 산업비밀, 핵심기술인력, 방위산업물자, 국가중요시설, 정보통신체계 등 다양한 보안요소를 포함하고 있다. 방위산업보안은 군사보안과 산업보안의 복합체이며 방위산업의 모든 보안요소를 통합하는 융합보안이다. 따라서 방위산업보안은 융합보안의 대표적인 실천모델이라고 할 수 있다. 방위산업보안에 대한 연구는 일반적인 다른 산업분야에서의 보안과 관련된 연구에 비해 미흡한 실정이다. 방위산업의 핵심기술 유출을 방지하고 기술인력 및 시설을 보호하기 위해서, 방위산업보안을 융합보안의 개념에서 연구하고 실천하는 노력이 절실한 시점이다.
