페이스북이나 트위터 같은 소셜 네트워킹은 최근 몇 년간 큰 인기를 얻고 있다. 매우 많은 사용자가 엄청난 양의 정보를 네트워크상에서 주고받기 때문에, 소셜 네트워크 서비스가 악의적인 사용자들에게는 유용한 공격수단이 될 수 있다. 많은 서비스 제공업체들이 그러한 취약점을 보완하기 위해서 노력을 하지만, 다양한 공격방법들이 새롭게 개발되면서 여전히 소셜 네트워크 서비스 사용자들을 위협하고 있다. 따라서 본 고에서는 온라인 소셜 네트워크에서의 프라이버시 및 보안 이슈를 점검해 보고자 한다.

한국증권산업은 최근 5년 동안 증권서비스의 거래방식이 오프라인에서 온라인으로 전환되는 급격한 패러다임의 변화를 겪었다. 이는 온라인 증권서비스가 오프라인에서 제공해 주지 못했던 서비스를 제공해 주었기 때문인 것으로 많은 연구를 통해 밝혀 졌다. 또한 정보통신기술의 급격한 발달과 모바일 기기의 빠른 보급으로 인하여 또다시 증권서비스의 거래 방식이 모바일기기를 이용한 방식으로 점차적으로 전환 될 것이라는 전망이 많이 예측 되었다. 그러나 전문가들이 예상했던 것과는 달리 모바일 증권서비스의 확산 속도는 2003년 온라인 증권 거래 방식 중 모바일 증권서비스의 거래방식이 3% 미만의 비중을 차지하는 등, 그 확산 속도가 정체되거나 매우 느리게 진행되고 있는 실정이다. 이에 본 연구에서는 초기에 많은 전문가들이 예상했던 모바일증권서비스가 활성화 되지 않는 요인을 장애요인으로 정의하고, 사용자들이 모바일증권서비스의 수용의도에 있어서 무엇이 가장 큰 장애요인 인지를 도출해 내고 도출된 장애요인을 실제 온라인 증권서비스 사용자들에게 검증 받는데 그 연구목적이 있다.

This paper describes the design and implementation of a 3-tiered proxy driving system utilizing smartphones. This system provides customers with a convenient request facility, and enables proxy drivers to provide a prompt service based on customer's location information. Implemented system supports two methods such as the existing phone-call and the online requesting method using smartphones. Performance analysis shows that the higher the ratio of online requests, the greater the effect of decreasing of phone jockey's workloads and the reduction of request processing time through the automation of receipt and processing. From a proxy driver company's standpoint, this system minimizes the increase of phone jockeys, and improves customer satisfaction through good service quality. This system also helps the company reduce the cost and increase the market share.

The development of Internet technology has brought the era of one-man media. An individual produces content on user own and uploads it to related online services, and many users watch the content of online services using devices that allow them to use the Internet. Currently, most users find and watch content they want through search functions provided by existing online services. These features are provided based on information entered by the user who uploaded the content. In an environment where content needs to be retrieved based on these limited word data, user unwanted information is presented to users in the search results. To solve this problem, in this paper, the system actively analyzes the video in the online service, and presents a way to extract and reflect the characteristics held by the video. The research was conducted to extract morphemes based on the story content based on the voice data of a video and analyze them with big data technology.

Considering the continuous increase of teenagers' Internet use and the high rate of their participation in online communities, educators need to devote efforts to minimize the negative function of teenagers' Internet use and to guide them to experience positive aspects of Internet. Through activities in online communities, teenagers can experience various socialities and explore their self-consciousness. However, on the other hand many communities do not provide teenagers with considerate care. This may cause conflict in their sense of value and mislead them. Through this study, online learning community is designed and developed, which can reflect teenagers' various needs and connect their needs with learning experiences. The community consists of the following categories: 'about e-Tivity'(community vision, general information, list of activities, Q&A), 'activity space for teens'(event hall, data park, e-Tivity center), 'administrative space for teachers and managers'(research room, management room), and 'teen's private space'(my room, my avatar).

In the post-pandemic era, the demand for online education platforms has surged, leading to increased consumer reliance on online reviews for decision-making. This study investigates the impact of Chinese online customer reviews on consumer purchase behavior in online education. By examining the role of trust, review sentiment, and the quantity and timeliness of reviews, the research aims to understand how these factors influence consumer decisions. By using regression model, findings reveal that negative reviews, timely feedback, and a higher volume of reviews positively affect consumer purchase decisions, while course pricing demonstrates an inverse relationship. Furthermore, cognitive and affective trust mediate the relationship between reviews and purchase behavior, highlighting a reverse U-shaped effect on consumer decision inclination. These insights provide valuable implications for online education providers, emphasizing the need to manage and leverage online reviews to foster consumer trust and improve sales performance.
