The purpose of this study is to determine how the use of retailtech technology affects consumers' purchase intention. Furthermore, this study aims to investigate the mediating effects of technology usefulness and ease of use on this influence relationship and whether experiential marketing moderates consumers' purchase intention. The survey was conducted from August 1, 2023 to September 30, 2023, and a total of 257 people participated in the study. For statistical analysis, hierarchical regression analysis, three-stage mediation regression analysis, and hierarchical three-stage controlled regression analysis were conducted to test the hypothesis. The results of the study are as follows. First, it was confirmed that big data-AI utilization, mobile-SNS utilization, live commerce utilization, and IoT utilization affect purchase intention in retail technology utilization. Second, technology usefulness has a mediating effect on IoT utilization, mobile-SNS utilization, and big data-AI utilization. Third, perceived ease of use of technology mediated the effects of IoT utilization, mobile-SNS utilization, live-commerce utilization, and big data-AI utilization. Fourth, escapist experience has a moderating effect on mobile SNS utilization and live commerce utilization. Fifth, esthetic experience has a moderating effect on mobile-SNS utilization and big data-AI utilization. Through this study, we hope that the domestic distribution industry will contribute to national competitiveness by securing the competitive advantage of companies by utilizing new technologies in entering the global market.

Emerging hotspot and trendy areas are formed into alleys and blocks with the help of viral effects among social network services (SNS) users called "Golmogleo." These users search for every corner of the alleys to share and promote their own favorite places through SNS. An analysis of hot places is limited if it is only based on macroeconomic indicators such as commercial area data published by national organizations, large-scale visiting facilities, and commuter figures. Careful analyses based on consumers' actual activities are needed. This study develops a "social big data analysis methodology" using Instagram data, which is one of the most popular SNSs suitable to identify recent consumer trends. We build a spatial analysis model using Local Moran's I. Results show that our model identifies new trend zones on the basis of posting data in Instagram, which are not included in the commercial information prepared by national organizations. The proposed analysis methodology enables better identification of the latest trend areas formulated by SNS user activities. It also provides practical information for start-ups, small business owners, and alley merchants for marketing purposes. This analytical methodology can be applied to future studies on social big data analysis.

대규모의 데이터가 생산되고 저장되는 정보화 시대에서 현재와 과거의 데이터를 바탕으로 미래를 추측하고 방향성을 알아갈 수 있는 빅데이터의 중요성이 강조되고 있다. 정형화 되지 못한 대규모 데이터를 빅데이터 분석 도구인 R과 웹크롤링을 통해 분석하고 그 통계를 기초로 데이터의 정형화와 정보 분석을 하도록 한다. 본 논문에서는 R과 웹크롤링을 이용하여 최근 이슈가 되고 있는 벤처창업을 주 키워드로 하여 뉴스 및 SNS에서 나타나는 벤처창업 관련 빅데이터를 분석한다. 뉴스기사와 페이스북, 트위터에서 벤처창업 관련 데이터를 수집하고 수집된 데이터에서 키워드를 분류하여 효율적인 벤처창업의 방법과 종류, 방향성에 대해 예측한다. 과거의 벤처창업 실패요인을 분석하고 현재의 문제점을 찾아 데이터 분석을 통해 벤처창업의 흐름과 방향성을 제시하여 창업자들이 겪을 수 있는 어려움을 사전에 예측하고 파악함으로써 실질적인 벤처창업에 크게 이바지할 것으로 보여 진다.

Research on what factors affect the success of the movie market is very important for reducing risks in related industries and developing the movie industry. In this study, in order to find out the degree of correlation of independent variables that affect movie performance, a survey was conducted on film experts using the AHP method and the importance of each measurement factor was evaluated. In addition, we hypothesized that factors derived from big data related to search portals and SNS will affect the success of movies due to the increase in the spread and use of smart phones. And a prediction model that reflects both the expert survey information and big data mentioned above was proposed. In order to check the accuracy of the prediction of the proposed model, it was confirmed that it was improved (10.5%) compared to the existing model as a result of verification with real data.Therefore, it is judged that the proposed model will be helpful in decision-making of film production companies and distributors.

The ICT (information and communication technology) paradigm shift, including the burgeoning use of mobile, SNS, and smart devices, has resulted in an explosion of data along with lifestyle changes. We have thus arrived at the age of big data. In the meantime, a number of difficulties have arisen in terms of cost or on the technical side with respect to the use of large quantities of data. However, big data has begun to receive attention with the advent of efficient big data technologies such as Hadoop. In this paper, we discuss the patent analysis of big data platform technology research and development in major countries. Especially, we analyzed 2,568 patent applications and registered patents in four countries on December 2010.

The era of Big Data has come and the importance of Big Data has been rapidly growing. The part of transportation, the Four-Step Travel Demand Model(FSTDM), a traditional Trip-Based Model(TBM) reaches its limit. In recent years, a traffic demand forecasting method using the Activity-Based Model(ABM) emerged as a new paradigm. Given that transportation means the spatial movement of people and goods in a certain period of time, transportation could be very closely associated with spatial data. So, I mined Spatial Big Data from SNS. After that, I analyzed the character of these data from SNS and test the reliability of the data through compared with the attributes of TBM. Finally, I built a database from SNS for the operation of ABM and manipulate an ABM simulator, then I consider the result. Through this research, I was successfully able to create a spatial database from SNS and I found possibilities to overcome technical limitations on using Spatial Big Data in the transportation planning process. Moreover, it was an opportunity to seek ways of further research development.

정보통신 기술(ICT)의 발달로 이루어진 4 차 산업혁명으로 '빅데이터'의 시대가 도래하고 있다. 소셜 네트워크 서비스(SNS), 사물인터넷(IOT), 인공지능(AI) 등 다양한 장소에서 다양한 형태로 데이터들이 쌓이고 있다. 그중 MBTI 성격유형 검사를 통한 다양한 분석 시스템이 많아지고 있다. 사람들은 재미를 위해 자신의 성향을 입력하고 정해진 MBTI 검사 기준을 통해 결과를 받는다. 이러한 개개인의 성향 데이터를 모으면 거대한 빅데이터 플랫폼을 만들 수 있을 것이라 기대한다. 이에 본 논문은 구체적인 방안을 제시하고자 한다.

매년 국지성호우 및 태풍으로 인해 하천 범람이나 저지대침수가 발생하고 있으며 이는 인명 피해 사례로 이어지기도 한다. 피해 발생을 최소화시키기 위해 강우와 유량과 같은 정형데이터로 홍수예보가 이뤄지고 있으나 기존의 정형데이터만 사용하다보니 도심지역이나 소규모 하천에서 인명 피해 예측에 어려움이 있다. 이를 보완하기 위해서는 인구의 유동성을 고려한 비정형데이터를 활용해야 한다. 최근 소셜 네트워크 서비스(SNS)의 사용자가 증가됨에 따라 텍스트나 사진과 같은 다양한 비정형데이터가 생성되고 있다. 이렇게 생성된 데이터는 다양한 분야에서 활용되고 있으며 특히 지진이나 홍수와 같은 재난 발생 시 유용한 데이터로 활용된 사례가 증가하고 있다. 이는 사람들이 GIS와 같은 위치정보나 시간 등을 포함한 다양한 정보를 포함하기 때문이다. 하지만 이렇게 생산된 비정형데이터를 기존 물리적 기반의 수문모형의 데이터로 활용하기에는 많은 한계점이 있다. 따라서 본 연구에서는 SNS 채널을 통해 생성된 비정형 데이터들을 인공신경망모형에 적용하여 하천수위를 예측하였다.

Recently, SNS (Social Network Service) such as Twitter and Facebook has grown dramatically because of smart phones. Since development of IT has created massive information, social big data extremely increased. Competition between corporations is getting more intense, so they need customer feedback in order to fulfill an effective management. Because social big data plays an important role for getting customer feedback, a lot of corporations are interested in analyzing and applying of social big data. Collecting and analyzing social big data is operated by Buzz monitoring system. This paper demonstrates the research of buzz monitoring system that analyzes big data, and presents examples of customer reputation using buzz monitoring. In the paper, after all, it would analyze the result from the customer reputation, and research the implication.
