The process and change of convergence in the economy and industry with the development of digital technology and combining with new technologies is called Digital Transformation. Specifically, it refers to innovating existing businesses and services by utilizing information and communication technologies such as big data analysis, Internet of Things, cloud computing, and artificial intelligence. Digital transformation is changing the shape of business and has a wide impact on businesses and consumers in all industries. Among them, the big data and analytics market is emerging as one of the most important growth drivers of digital transformation. Integrating intelligent data into an existing business is one of the key tasks of digital transformation, and it is important to collect and monitor data and learn from the collected data in order to efficiently operate a data-based business. In developed countries overseas, research on new business models using various data accumulated at the level of government and private companies is being actively conducted. However, although the trade and import/export data collected in the domestic public sector is being accumulated in various types and ranges, the establishment of an analysis and utilization model is still in its infancy. Currently, we are living in an era of massive amounts of big data. We intend to discuss the value of trade big data possessed from the past to the present, and suggest a strategy to activate trade big data for trade digital transformation and a new direction for future trade big data research.

This study aims to analyze international trade papers published in Korea during the past 2002-2022 years. Through this study, it is possible to understand the main subject and direction of research in Korea's international trade field. As the research mythologies, this study uses the big data analysis such as the text mining and Social Network Analysis such as frequency analysis, several centrality analysis, and topic analysis. After analyzing the empirical results, the frequency of key word is very high in trade, export, tariff, market, industry, and the performance of firm. However, there has been a tendency to include logistics, e-business, value and chain, and innovation over the time. The degree and closeness centrality analyses also show that the higher frequency key words also have been higher in the degree and closeness centrality. In contrast, the order of eigenvector centrality seems to be different from those of the degree and closeness centrality. The ego network shows the density of business, sale, exchange, and integration appears to be high in order unlike the frequency analysis. The topic analysis shows that the export, trade, tariff, logstics, innovation, industry, value, and chain seem to have high the probabilities of included in several topics.

통계에 의하면 국내 중소기업들은 자금조달의 대부분을 은행 대출에 의존하고 있는 것으로 나타나고 있다. 그러나 담보가 없고 금융거래 이력도 부족한 소상공인들은 은행으로부터 대출을 받는데 어려움을 겪고 있다. 재무제표 등 은행에서 신용평가를 위하여 필요로 하는 정보를 제공하지 못하는 금융정보부족 (Thin File) 때문이다. 이러한 문제를 타개하기 위해서 최근 P2P 등 대안금융에서는 기존의 금융정보 대신 핀테크를 활용한 인구통계, 거래정보 등 차별화된 정보들을 이용하여 소규모 자금을 소상공인들에게 제공하는 새로운 신용평가기법들이 확산되고 있다. 이러한 환경 변화 패러다임 속에서 본 연구는 매출액 변동, 입지조건 등 상권정보에 기초한 빅데이터를 활용하여 소상공인들에게 자금공급을 확대할 수 있는 신용평가방안을 모색하고자 한다. 상권에서 발생하는 빅데이터를 실증적으로 분석함으로써 신용평가요소로서의 효과성을 검증하여 소상공인의 사업성 평가에 필요한 주요변수들을 도출하고자 하는 것이다. 본 연구에서는 2009년에서 2018년 2월까지 서비스업을 영위하는 서울시 소재 사업체 17,116건을 대상으로 사업체의 위치별로 발생하는 상권정보를 빅데이터 전문기업 NICE지니데이터(주)로부터 수집하여 표본을 구성하였다. 소상공인들에게서도 어렵지 않게 구할 수 있는 사업장의 입지 및 상권과 관련된 빅데이터를 수집 분석하여 이들 데이터가 기업의 부실화에 영향을 미치는가를 분석하였다. 기존에 활용되지 못한 빅데이터 변수들을 탐색하여 소상공인에 대한 효율적인 금융지원에 활용 가능성을 확인함으로써 대부분 정책자금이나 담보에 의존하여 이루어지는 소상공인대출이 일반 상업은행에서도 중소기업대출의 한 부문으로 비중 있게 이루어질 수 있도록 하기 위함이다. 본 연구는 근본적으로 정보비대칭 (Information Asymmetry)의 문제가 내재되어 있는 소상공인들의 자금조달에 관하여 전통적인 재무정보가 아닌 상권분석 변수들을 도출하고, 이 변수들이 신용평가에 효과성이 있는지 여부를 상권 빅데이터의 분석을 통하여 검증하였다는 점에서 연구의 차별성이 있다.

As the capacity of the 3d scanner developed, the reverse engineering using the 3d scanner is emphasized in the construction industry to obtain the 3d geometric representation of buildings. However, big size of the indoor point cloud data acquired by the 3d scanner restricts the efficient process in the reverse engineering. In order to solve this inefficiency, several pre-processing methods simplifying and denoising the raw point cloud data by the rough standard are developed, but these non-standard methods can cause the inaccurate recognition and removal the key-points. This paper analyzes the correlation between the accuracy of wall recognition and the density of the data, thus proposes the proper method for the raw point cloud data. The result of this study could improve the efficiency of the data processing phase in the reverse engineering for indoor point cloud data.

The purpose of this study was to analyze big data to identify the sub-dimensions of ethical consumption, as well as the consumption value associated with ethical consumption that changes over time. For this study, data were collected from Naver and Daum using the keyword 'ethical consumption' and frequency and matrix data were extracted through Textom, for the period January 1, 2016, to December 31, 2018. In addition, a two-way mode network analysis was conducted using the UCINET 6.0 program and visualized using the NetDraw function. The results of text mining show increasing keyword frequency year-on-year, indicating that interest in ethical consumption has grown. The sub-dimensions derived for 2014 and 2015 are fair trade, ethical consumption, eco-friendly products, and cooperatives and for 2016 are fair trade, ethical consumption, eco-friendly products and animal welfare. The results of deriving consumption value keywords were classified as emotional value, social value, functional value and conditional value. The influence of functional value was found to be growing over time. Through network analysis, the relationship between the sub-dimensions of ethical consumption and consumption values derived each year from 2014 to 2018 showed a significantly strong correlation between eco-friendly product consumption and emotional value, social value, functional value and conditional value.
