In this study, the network formation process of personal actors in industries for the elderly was analyzed. This process is applied to the knowledge creation model of the SECI (Nonaka-Takeuchi learning cycle), that is socialization, externalization, combination, internalization. There are some kinds of opportunities to interact in these industries in the forms of field survey teams to overseas, some seminars and symposiums, many kinds of meetings, education and training programs, trade fairs and on-line forums. These palces(ba) - originating ba, interacting ba, cyber ba, exercising ba - played great roles in the formation of personal actor networks. Personal actors had opportunities to interconnect with distant actors through those places(ba). In the spatial perspective, personal actors could make face-to-face contact and build trust through temporary geographical proximity or temporary clusters with the help of personal mobility. Relations in the virtual spaces such as the Internet community did much toward building personal networks.

사이버커뮤니티의 발전상은 까페, 싸이, 블로그, 휴대폰 등의 형태로 개체화와 나열형 정보에 주력되어, 정보홍수로 인한 역설적 정보빈곤의 부작용 또한 커지고 있다. 이에 본 논문에서는 나열형 정보의 단점을 극복할 수 있는 공유형 정보의 구현방안으로서, '의미소개체화 기반 게임형토론시스템'을 제안한다. 기존에 나열형 정보의 대안이자 웹 2.0의 모델로 주목받아온 위키(wiki)방식의 원론적 공유에서 나아가, 구성개체 간 상호평가가 수치로 교환되고 그에 따른 가중치가 활용되는 방안이다. 이는 시맨틱 웹과 웹2.0의 통합적 논의이며, 인터넷의 자연스런 발전방향이다. 이 시스템이 구현된 인터넷(Internet)을 포럼넷(Forumnet)이라 부를 수 있다. 포럼넷은 현실적, 기술적으로 개인기반평가에서 개체기반평가로 구현되어갈 것이다.

Industry 4.0의 진행으로 이기종의 IoT 장비들 간의 통신을 위해 다양한 산업용 통신 미들웨어들이 등장했다. 그 중 Robotics 분야에서 활발히 사용되는 Robot Operating System (ROS)는 개발자 커뮤니티와 로봇 개발 도구들을 기반으로 지속적인 시장 점유율 증가세를 보이고 있다. 초기 발표된 ROS1의 경우 보안이 전혀 고려되지 않은 설계로 Packet Injection 공격등의 사이버 보안 위협에 취약했지만, ROS2의 경우 통신 미들웨어인 Data Distribution Service (DDS) 통신규격을 전송 계층에 적용하여 메시지 전송에 대한 보안 기능을 제공하고 있다. 그러나 최근 연구에서는 DDS와 관련된 ROS2 취약점이 발표되고 있다. 따라서 본 논문에서는 DDS와 관련된 ROS2의 공격 기술 동향을 소개한다.

First, although the vast majority of adolescents (96.9%) had a computer at home, majority of adolescents visited Internet cafe. Second, 70.3% of adolescents visited Internet cafe to play Internet games, followed by engaging in information search, chatting, and participated in cyber community. Third, on average adolescents spent 5.43 hours per week playing Internet games, with more males playing Internet games than female adolescents. As for information search, the weekly average was 2.60 hours, with university students spending more time than the other groups. As for chatting, the weekly average was 1.69 hours, with no significant differences among the groups. The weekly average of Internet use was 9.65 hours, with older groups spending more time. The weekly average use of computer was 10.91 hours, with older groups spending more time and more males using more computer than females. Fourth, as for self-concept in cyberspace, elementary and middle school students reported that they had fun, while high school and university students reported that they were the same as in the regular daily life. In addition, adolescents reported that they spent leisure activity in cyberspace and they become a fictional character in cyberspace. Fifth, when they played Internet games, regardless of age and gender, adolescents reported that they had fun, followed by that they were absorbed, that they became aggressive, and that they were the same as in the regular daily life. Sixth, when they chatted on Internet, regardless of age and gender, adolescents reported that they had fun, followed by that they were not interested, that they were the same as in the regular daily life, and that they do not chat on Internet. Seventh, when they interacted with their friends on Internet, regardless of age and gender, majority of adolescents reported that they had fun, followed by that they conversed, that they were the same as in the regular daily life, and that they felt closer. These results indicate that Korean adolescents view Internet as a place to spend their leisure time and that they enjoyed spending time on Internet.

Online communities have become playgrounds for enjoyment and political public spheres as well as have been vitalized by participation of diverse users, which shows that users of online communities experience participatory democracy and new subjects who project the politic of everyday life eventually. The purpose of the study is to examine that how phenomenon from above have been revealed in the academic discourses and seek the ways for development of the theory and methodology of community media research. To do this, I analyze that features and tendencies of academic discourses which have historically been accumulated through applying method of meta-analysis into topics, methods, and issues in the precedence studies. Data is centered on Journals of the Korean Society for Journalism and communication Studies, Korean Association for Broadcasting and Telecommunication studies, Korean Association for Communication and Information studies, and the Cybercommunication Academic Society. The reason why I choose these journals is that they have a long history of the publication compared to other journals, thus, I can collect various related articles. Total of 53 Samples are selected after input keywords '공동체' and 'Community'. This study makes a contribution by offering the preliminary data in order to seek the ways for revitalization of local communities and for the future theories and methodologies of community media through researching on precedence studies having piled from 2001 when the first article about community media was published to November 2016.

Recently, discussions for the eradication of illegal shooting have been carried out in a socially-oriented way. The government has established comprehensive measures to eradicate cyber sexual violence crimes such as illegal shooting. Although the social interest in illegal shooting has increased, the illegal film shooting case is evolving more and more due to the development of information and communication technology. Applications that can hide confused videos are constantly circulating around the market and community sites. As a result, field investigators and professional analysts are experiencing difficulties in collecting and analyzing evidence. In this paper, we propose an evidence collection and analysis framework for illegal shooting cases in order to give practical help to illegal shooting investigation. We also proposed a system that can detect hidden applications, which is one of the main obstacles in evidence collection and analysis. We developed a detection tool to evaluate the effectiveness of the proposed system and confirmed the feasibility and scalability of the system through experiments using commercially available concealed apps.

One of the social aspects that changes as the use of the Internet becomes widespread is communication in online space. In the past, only one-on-one conversations were possible remotely, except when they were physically in the same space, but nowadays, technology has been developed to enable communication with a large number of people remotely through bulletin boards, communities, and social network services. Due to the development of such information and communication networks, life becomes more convenient, and at the same time, the damage caused by rapid information exchange is also constantly increasing. Recently, cyber crimes such as sending sexual messages or personal attacks to certain people with recognition on the Internet, such as not only entertainers but also influencers, have occurred, and some of those exposed to these cybercrime have committed suicide. In this paper, in order to reduce the damage caused by malicious comments, research a method for improving the performance of discriminate malicious comments through feature extraction based on parts-of-speech.
