Why illegal digital contents sharing happens? This study pays attention to the fact that file sharing is an exchanging behavior between people and it is expanding despite of an illegal behavior and proposes that it is necessary for the phenomenon to be understood from social cultural point of view beyond a personal dimension. Based on the social exchange theory, this study demonstrates effects of file sharing attitudes and continuity, regarding 'group norm', 'popular demand', 'reciprocity' and 'social solidarity' as main factors. The main findings of this study are as followed;- First, it is shown that a tacit agreement of a group on file sharing is a determinant of positive attitude to file sharing and the intent of continual file sharing. Second, it is not found that the social relationship factors that are regarded as potential influential factors on file sharing attitude have effects on file sharing behavior, except for 'group norm'. Unlike previous studies, the results may come from the fact that this study deals with an illegal behavior. The third finding indicates a structural relationship between social relationship factors. When members of a group have more amicable attitude to file sharing including silence or a tacit agreement on file sharing, more people ask illegal sharing of files that they need. Such public demand creates expectation of reciprocity. As reciprocity maintains, social connectedness is strengthened. Then, strong social connectedness escalates the intent to maintain file sharing. It is important to notice that this study promotes understanding of how digital contents sharing happens by structuring and demonstrating influential relationship between characteristic factors of the social relationship.

In order to reduce the spread of illegal digital contents, many studies have been focusing on how to stop it through laws and regulations. Only few of the studies tried to explain the illegal behaviors from individual's viewpoints. This paper aims to examine the intention of sharing illegal digital contents over the Internet and proposes a theoretical model based on the Theory of Planned Behavior (TPB) along with the introduction of two outcome expectations. We also argue that the individuals' cognition of online copyright will influence individuals' illegal contents sharing on the Internet. We have collected data from online survey and offline interview. By empirical study, the results support the theoretical model except the subjective norm which has no effect on individuals' behavior. This is a different finding from the previous researches revealing that the subjective norm has no effect on individuals' unethical actions. Overall, the findings provide strong confirmation that attitude, self-efficacy and outcome expectations impact on individual's intention of sharing illegal contents. In addition, this study proposed an improved cognition of online copyright through education and standard of new media management will reduce illegal contents sharing on Internet.

The purpose of this study was to analyze the effects of online writing contents on college students' learning strategy, achievement motivation, and knowledge sharing attitudes. Online writing contents were developed in the 4th class and operated as a extracurricular. The contents were developed in 25 minutes and included quizzes for learning activities. Changes in learning strategy, achievement motivation, and knowledge sharing attitude were analyzed for 149 students who finally completed online writing contents operated as a extracurricular. As a result of the analysis, it was found that online writing contents had a significant effect on college students' learning strategy, achievement motivation, and knowledge sharing attitude. Online contents is not limited by time and space, and since it can be used according to the learning plan, the utilization effect is attracting attention. Therefore, it is necessary to conduct various studies such as developing contents tailored to the needs of students and analyzing their effects.

본 논문에서는 분산된 협업 환경을 통합하는 콘텐츠 공유 모델을 제안한다. 확장 가능한 고해상도 디스플레이 자원, 로컬 및 원격 콘텐츠 공유, 다중 사용자 상호작용 및 접근제어 특성들을 통합하여 결합된 하나의 모델을 제공한다. 다중 사용자의 상호 작용은 모든 사용자가 상호 작용이 가능하다는 이점이 있지만, 그로 인해 오버랩이 발생할 수 있다. 그 오버랩을 관리하기 위해 접근 제어를 모델에 적용했으나 작업 흐름의 방해가 가능하다. 따라서 이 두 가지 사항을 중점으로 모델을 평가하기 위해 상호작용성에 대한 이용자 연구를 실시했다. 그 결과를 바탕으로 제안된 콘텐츠 공유 모델은 상호작용과 그 흐름을 방해 하지 않아 작업에 집중할 수 있는 분산 협업 환경을 제공한다.

소프트웨어 제작자들이 불법복제로부터 그들의 제품을 보호하기 위해 노력하는 것처럼 콘텐츠 제작자들도 사용자간 불법 콘텐츠 공유를 규제하기 위해 노력하고 있다. 본 연구는 이러한 시도가 과연 저작권자의 권익을 보호하고 그들의 수익을 극대화할 수 있는 근본적인 해결책이 될 수 있을 것인지에 대하여 경제적 측면에서 논의한다. 이를 위해 불법 콘텐츠 공유에 대한 규제가 제작자의 수익에 미치는 효과를 파악하기 위한 분석적 모형을 개발하고 규제와 비 규제하에서 콘텐츠 제작자의 수익극대화를 위한 최적 조건을 제시한다. 분석결과, 정품 콘텐츠와 불법 복제 콘텐츠간의 충분한 차별화가 어려운 경우에는 불법 복제의 규제가 긍정적인 효과를 줄 수 있으나 정품 콘텐츠와 불법 복제 콘텐츠 사이에 충분한 차별화가 가능한 경우에는 오히려 규제가 없는 경우에 저작권자의 수익이 극대화되는 것으로 나타났다.

These days, anyone can easily product and share their own content through a web service such as blogs and SNS. However, contents are being operated separately because of the space limitation in individual SNS. Therefore, it is hard to search contents efficiently in individual SNS. To solve this problem, this paper propose a "Private Contents Management and Sharing Service with Voluntary Sharing Economy System." The system is in part [Input], [Save] and it provides a way to collect the content that are scattered on the Internet based on the creation of personal index. It also proposes a more systematic content management and sharing by creating and updating the website standard index by introducing an index Coordinator concept. Furthermore in [Use] section, by providing a portion of the index as the primary search results, it avoid unclassified content list which was simply collected by users. In conclusion, unlike previous studies, this system will contribute to the acquisition and management of interspersed content and ultimately contribute to the shared activation by preventing secondary processing and unauthorized processing to the original article.

Load sharing is a critical resource in computer system. In sender-initiated load sharing algorithms, the sender continues to send unnecessary request messages for load transfer until a receiver is found while the system load is heavy. Meanwhile, in the receiver initiated load sharing algorithms, the receiver continues to send an unnecessary request message for load acquisition until a sender is found while the system load is light. These unnecessary request messages result in inefficient communications, low CPU utilization, and low system throughput in distributed systems. To solve these problems, we propose a genetic algorithm based approach for improved sender-initiated and receiver-initiated load sharing in distributed systems. And we expand this algorithm to an adaptive load sharing algorithm. Compared with the conventional sender-initiated and receiver-initiated algorithms, the proposed algorithm decreases the response time and task processing time.

Due to the advancements in the capabilities of smart devices and home networks, we are able to easily access multimedia contents stored in a home server. In this paper, we present a wireless media content sharing mechanism for home networks that utilizes UPnP-based DLNA technology. We also present a novel Peer-to-Peer content sharing system that is able to operate on the client as well as server. Our system supports multiple push/pull services simultaneously via a multi-thread technique, and our intuitive user interface facilitates ease of use. Future studies would explore the feasibility of implementing our system in a multi-hop environment or providing a community-wide service.

A load sharing algorithm is one of the important factors in computer system. In sender-initiated load sharing algorithms, when a distributed system becomes to heavy system load, it is difficult to find a suitable receiver because most processors have additional tasks to send. The sender continues to send unnecessary request messages for load transfer until a receiver is found while the system load is heavy. Because of these unnecessary request messages it results in inefficient communications, low cpu utilization, and low system throughput. To solve these problems, we propose a self-adjusting evolutionary algorithm for improved sender-initiated load sharing in distributed systems. This algorithm decreases response time and increases acceptance rate. Compared with the conventional sender-initiated load sharing algorithms, we show that the proposed algorithm performs better.
