In this paper, authors focused on the difference between successful and unsuccessful items in terms of the innovation and imitation parameters of Bass diffusion model. Each item was scraped by members directly from the minihompies they visit. Top 50 items in terms of total number of adoption are classified as successful items and the 50 items whose total number of adoption was just below the average are classified as unsuccessful items. In particular, authors are interested in investigating the role of influentials in the diffusion process. Influentials are defined as those people whose network centrality (Indegree, Outdegree, and Betweeness centrality) was larger than the mean centrality in their social network. Figure 1 shows the plots of number of scraping, cumulative scraping, indegree, outdegree and betweenness of the people who scraped the most popular item among 100 items.

NIE(Newspaper-In-Education)는 신문을 활용한 교육을 말한다. NIE가 기존의 교육에 비하여 다양한 가치 인식을 통한 사회성 확립과 아울러 독해력과 작문력 향상, 정보 활용 능력의 육성 등의 장점이 있어서 교육 현장에서 널리 활용되고 있다. 그러나 기존의 NIE는 기사 스크랩의 번거로움, 복사 사용으로 인한 판독의 어려움, 전문용어에 대한 지도의 어려움 등의 문제점을 가지고 있다. 따라서 본 논문에서는 웹 기반 NIE를 위한 교수-학습 시스템을 설계한다. 웹 기반 NIE는 신문활용교육의 장을 교실과 가정에서 그대로 컴퓨터와 인터넷으로 옮겨온 것이다. 인터넷 신문을 통해 다양한 신문의 기사와 정보를 접하고, 분석하며 기존의 워크북(workbook)에서 하던 NIE 활동을 그대로 웹 기반으로 옳긴 것이다. 본 논문에서 설계한 웹 기반 NIE 교수-학습시스템은 신문지면을 준비하는 문제에 구애받지 않고, 전문용어에 대한 실시간 검색을 통한 빠른 이해와 다른 사람의 NIE 작품을 비교할 수 있는 둥의 장점을 가지고 있기 때문에 우리나라 NIE교육의 발전에 기여할 것으로 기대된다.

The concept of Web 2.0, which means that internet users are producers and also consumers is evolved according to the development of web service technology. In the Web 2.0 space, the enormous amount of web contents are produced using many social web services. Proactive display system supports various types of users's web contents. Unfortunately, private web contents sharing facility is imperfect to date. In this paper, we develop a proactive display application which identifies people, displaying their social contents such as blogs and open cafes through wide display devices or multi-media players in physical spaces. For this, we develop a social contents presentation server where users can register their profiles and information on the social contents to be shared through the developed application. Also, we develop a social contents presentation client that proactively identifies the user in close proximity and displays the user's social contents through an intuitive user interface in physical spaces. In addition, we develop an on-the-spot feedback service which supports posting various types of replies and an on-the-spot scrap service which specifies direct sharing of the contents through the intuitive user interface.

최근 ICT의 발전으로 인해 웹사이트 수가 폭발적으로 증가하고 있으며 인터넷상에는 여러 가지 다양하고 방대한 데이터들이 존재한다. 이러한 데이터를 효과적으로 검색하고 이용하기 위하여 웹 검색 기능은 주요한 역할을 담당한다. 본 논문에서는 웹 데이터를 자동으로 스크랩하여 파일로 저장하는 웹 크롤러를 구현하고 처리 속도 향상을 위하여 쓰레드 기능을 추가하였다. 웹 크롤러 구현을 위한 프로그래밍 언어는 파이썬을 사용하였으며 다양한 크기의 레퍼런스 사이트의 크롤링 속도 비교는 쓰레드 수를 변경함으로 측정하여 성능향상을 확인하였다.

In this paper, we analyzed the papers related to the "4th Industry". In order to analyze the papers, total of 685 papers were collected by searching with the keyword "4th industry" in Korea Journal Index(KCI) from 2016 to 2019. We used Python-based web scraping program to collect papers. As a result of analysis, it was confirmed that artificial intelligence, big data, Internet of things(IoT), digital, network and so on have emerged as the major technologies, and it was confirmed that research has been utilizing the major technologies in various fields related to the 4th industry such as industry, government, education field, and job.

In this research, text mining techniques were used to analyze the papers related to the "4th Industry". In order to analyze the papers, total of 685 papers were collected by searching with the keyword "4th industry" in Korea Journal Index(KCI) from 2016 to 2019. We used Python-based web scraping program to collect papers and use topic modeling techniques based on LDA algorithm implemented in R language for data analysis. As a result of perplexity analysis on the collected papers, nine topics were determined optimally and nine representative topics of the collected papers were extracted using the Gibbs sampling method. As a result, it was confirmed that artificial intelligence, big data, Internet of things(IoT), digital, network and so on have emerged as the major technologies, and it was confirmed that research has been conducted on the changes due to the major technologies in various fields related to the 4th industry such as industry, government, education field, and job.
