As the safety fields are expanding to a variety of industrial fields, safety technology has been developed by convergence between industrial safety fields such as mechanics, ergonomics, electronics, chemistry, construction, and information science. As the technology convergence is facilitating recently advanced safety technology, it is important to explore the trends of safety technology for understanding which industrial technologies have been integrated thus far. For studying the trends of technology, the patent is considered one of the useful sources that has provided the ample information of new technology. The patent has been also used to identify the patterns of technology convergence through various quantitative methods. In this respect, this study aims to identify the convergence patterns and fields of safety technology using association rule mining(ARM)-based patent co-classification(co-class) analysis. The patent co-class data is especially useful for constructing convergence network between technological fields. Through linkages between technological fields, the core and hub classes of convergence network are explored to provide insight into the fields of safety technology. As the representative method for analyzing patent co-class network, the ARM is used to find the likelihood of co-occurrence of patent classes and the ARM network is presented to visualize the convergence network of safety technology. As a result, we find three major convergence fields of safety technology: working safety, medical safety, and vehicle safety.

This study suggests a new approach for identifying core robot tech-nologies based on technological cross-impact. Specifically, the approach applies data mining techniques and multi-criteria decision-making methods to the co-classification information of registered patents on the robots. First, a cross-impact matrix is constructed with the confidence values by applying association rule mining (ARM) to the co-classification information of patents. Analytic network process (ANP) is applied to the co-classification frequency matrix for deriving weights of each robot technology. Then, a technique for order performance by similarity to ideal solution (TOPSIS) is employed to the derived cross-impact matrix and weights for identifying core robot technologies from the overall cross-impact perspective. It is expected that the proposed approach could help robot technology managers to formulate strategy and policy for technology planning of robot area.

글로벌 폴더블 디스플레이 시장은 최근 업체들 간 치열한 경쟁이 벌어지고 있어, 정확한 기술 동향 분석을 통한 전략적 기술기획이 요구되고 있다. 기술기획을 위한 분석 방법으로서의 특허분석은 그 개방성, 정형성, 기술에 대한 상세정보 등의 데이터 특성으로 인해 현장에서 자주 활용되고 있다. 그런데 이 가운데 정성분석은 특허의 내용을 건별로 파악하여야 하는 관계로 시간과 비용의 문제가 발생하며, 전통적인 정량분석은 주로 특허의 수에 의존함으로써 특허의 내용 및 기업별 핵심기술을 파악하는 데 한계가 존재한다. 따라서 본 연구에서는 특허의 동시분류 네크워크 분석 방법을 활용하여 기업별 핵심기술을 분석해 보고자 하였다. 분석 결과, 폴더블 디스플레이 관련 특허 출원은 2014년부터 급격히 성장하여 출원 기업의 92%가 한국의 2개 패널 제조사(SDC 및 LGD)와 2개 세트 제조사(SEC 및 LGE)의 출원으로 확인되었다. 동시분류 네트워크를 분석해 본 결과, 패널 제조사인 SDC와 LGD는 핵심기술 분야가 서로 유사한 반면, 세트 제조사인 SEC와 LGE는 눈에 띄는 차별성이 존재함을 확인하였다. 이러한 결과는 본 분야 기업의 기술전략에 대한 시사점을 제공한다. 또한 특허 동시분류 네트워크를 통해서만 확인이 가능한 것으로, 이 분석이 기업 기술전략에 유용하게 활용될 수 있음을 확인하였다.

A primary concern of national R&D plans is to encourage technological development in private firms and research institutes. For effective R&D planning and program support, it is necessary to assess technological impacts that may exist both directly and indirectly among technology areas within the whole technology system; however, previous studies analyze only direct impacts among technologies, failing to capture both direct and indirect impacts. Therefore, this study proposes an approach based on decision-making trial and evaluation laboratory (DEMATEL) to identifying specific characteristics of technology areas, such as technological impact and degree of cause or effect (DCE). The method employs patent co-classification analysis to construct a technological knowledge flow matrix. Next, to capture both direct and indirect effects among technology areas, it incorporates the modified DEMATEL process into patent analysis. The method helps analysts assess the technological impact and DCE of technology areas, and observe their evolving trajectories over time, thereby identifying relevant technological implications. This study presents a case study using Korean patents registered during 2003-2012. We expect our analysis results to be helpful input for R&D planning, as well as the suggested approach to be incorporated into processes for formulating national R&D plans.

Purpose: As most defense technologies are classified as confidential, the corresponding International Patent Classifications (IPCs) require special attention. Consequently, the list of defense-related IPCs has been managed by the government. This paper aims to evaluate the defense-related IPCs and propose a methodology to revalidate and improve the IPC classification scheme. Methods: The patents in military technology and their corresponding IPCs during 2009~2020 were utilized in this paper. Prior to the analysis, patents are divided into private and public sectors. Social network analysis was used to analyze the convergence structure and central defense technology, and association rule mining analysis was used to analyze the convergence pattern. Results: While the public sector was highly cohesive, the private sector was characterized by easy convergence between technologies. In addition, narrow convergence was observed in the public sector, and wide convergence was observed in the private sector. As a result of analyzing the core technologies of defense technology, defense-related IPC candidates were identified. Conclusion: This paper presents a comprehensive perspective on the structure of convergence of defense technology and the pattern of convergence. It is also significant because it proposed a method for revising defense-related IPCs. The results of this study are expected to be used as guidelines for preparing amendments to the government's defense-related IPC.
