This study explored the perception of internet media credibility and influencing factors among college students who are routine users of internet-based media. Media literacy competences are of primary interest among others in that users' media literacy such as information evaluation, critical understanding of media, and information sharing are assumed to be related to media credibility. The results of analysis revealed critical understanding ability to be statistically significant and consistently influencing factor. Users with more critical view on media ownership, represented reality, commercial intention of media seemed less likely to trust internet media. Whereas media use motive for information was found to be a strong predicting factor, motive for pleasure showed no relationship with credibility. Based on the findings, suggestions for new research and limitations of the study were discussed.

The purpose of this study is to explore the diversity of French learning materials and suggest a learning method to increase the efficiency of learning. In the first part, we explore the linguistic characteristics of the proverb. In the second part, we present the examples that can be utilized in actual learning. In terms of teaching methods, sharing a common cultural consciousness is important for language and communication between interlocutors. In view of this point, the proverb has an extremely important value in the linguistic dimension. It means that the proverb can serve as a very useful material for the comparison of the morphology and phonetics of French. The efficiency of learning can be increased if we can apply an adequate learning plan using proverbs in accordance to the learner's level and the learning contents.

Recently commercial mixed-reality devices have be launched and a variety of mixed-reality content has produced, but narrow field of view, which appear to be hardware technical limitations, are mentioned as an important issue for hindering immersion and limiting the scope of use. We propose a new innovative system that cooperate multiple beam projectors and a number of mixed reality devices. Using this technology, users can maximize immersion and minimize frustration of narrow viewing angles through 3D object rendering on background of large 2D screens. This system, named BtS (Beyond the Sight), is implemented on a client-server basis and includes the ability to calibrate between devices, share spatial coordinate systems, and synchronize real-time renderings as core modules. In this paper, each configuration module is described in detail and the possibility of its performance and application is shown through the introduction of mixed reality content case created using BtS system.

People can easily use a shared economic service system based on ICT technology. Most of the shared economic services are provided by private companies, and discussion on public goods is insufficient. If we look at the current shared economic service from the point of view of courier service, $\ddot{U}ber^{\prime}s$ system can be an alternative. The post office courier service uses ICT technology but differs from the service of the shared economy. This study uses Delphi analyzer method and AHP methodology to derive important factors in introducing shared economic system. As a result, socioeconomic characteristics were found to be the most important in the upper tier, and the shared economic platform, sharing of idle resources, popularization of smartphone, and increase of e - commerce were the four important factors in the lower tier. In order to maximize efficiency, which is the essence of the shared economy, the necessity of introduction into the shared economic system and important factors in the introduction of public goods are presented.

Media sharing platform such as YouTube have grown significantly in the mobile environment. This is a platform that allows users to select and view broadcast programs that are only available on TV through network-connected PCs and mobiles, and share their media content to communicate. Currently, in the era where mobile and TV broadcasts can be viewed equally, there is a time difference between the video and real-time screen transmitted to TV and mobile, different from the actual situation.We want this time difference to be realized in the same way as the real time, and there is a need for a system that can broadcast in a free environment at any time. Therefore, in this paper, a broadcasting system was designed and implemented in a mobile environment. The result of reducing the delay time difference due to the improvement of the processing method was obtained.

The purpose of DRM is to protect the copyrights of content providers and to enable only designated users to access digital contents. From the consumers' point of view, they have a tendency to go against complex and confusing limitations. Moreover, consumers' rights of use of the content obtained legally were frequently harmed by arbitrary limitations. The concept of Authorized Domain (AD) was presented to remove such problems. However, the previous work on authorized domain has two problems. The first is that it requires a rather expensive revocation mechanism for withdraw process. The second is that the modules still can play contents which are previously obtained even though they are currently out of the authorized domain. On the contrary, our scheme presents the content from being played by modules which are out of the domain for better security. Furthermore our scheme does not need to maintain a revocation list and prevent replay attack.

Hospitals store and manage personal and health information through the electronic medical record (EMR). However, vulnerabilities and threats are increasing with the provision of various services for information sharing in hospitals. Therefore, in this paper, we propose a model to prevent personal information leakage due to the transmission of patient information in EMR. A method for granting permission to securely receive and transmit patient information from hospitals where patient medical records are stored is proposed using OAuth authorization tokens. A protocol was proposed to enable secure information delivery by applying and delivering the record access restrictions desired by the patient to the OAuth Token. OAuth Delegation Token can be delivered by writing the authority, scope, and time of destruction to view patient information.This prevents the illegal collection of patient information and prevents the leakage of personal information that may occur during the delivery process.

This study chose the academic journals related with e-sports for analysis among the top tier journals of National Research Foundation of Korea from 2006 to 2011 to check the academic trend Beginning in 2006, the first study of e-sports was published in the journal related with e-sports. So, the studies from 2006 to 2011 were chosen for analysis. Using Research Information Sharing Service(RISS), the keyword 'e-sports' was searched. By virtue of this process, total 27 studies were selected as final analysis. So, the academic trends are as follows. In Korea, the studies related with e-sports have started from the beginning of 2000s with internet and then it spread out via cable TV. And then from the middle of 2000s, e-sports was discussed seriously. The early subject of the studies usually focused on the measurement of e-sports based on the strategic elements as a product. After that, game addiction and violent tendency which were one of the biggest issues were raised as a constant problem and it became the academic studies of user behavior. E-sports became a recreation culture of teenagers so it has been in charge of the role of exit and the problems related with it have continuously appeared. So, the academic studies tend to have departmentalization like immersion, addiction, sociality, self-regulation and etc. But, there was a tendency that the similar contents were repeated in the view point of subject and method while the subjects were departmentalized. So, for the systematic study of e-sports, development of the unique subject, study method and verification process should be conducted continuously.

Boundary Station is an evaluation index that was not reflected in the Seoul Metropolitan Urban Railroad Connected Eare Allocation. Boundary station is a station located at the boundary point of two transportation agencies sharing the same route, and track operation methods are divided into business management and maintenance management. Until now, the Connected Fare Allocation has evaluated the boundary stations from the perspective of business management. Meanwhile, the integrated public transportation fee system requires the need to interpret the boundary stations from the point of view of maintenance management at the developmental level. This study was prepared a measure to quantitatively analyze changes in income with the introduction of maintenance methods in mind. The Change in the income of operation agency evaluated based on the daily transportation card data for the boundary stations of the four Seoul Transportation Corporation and KORAIL sections. This study is meaningful as a basic research for an analytical judgment that evaluates and allocates changes in transportation income of Seoul Metropolitan Urban Railroad in the future.

As an IETF standard protocol, WebDAV provides infrastructure for managing and authoring resources and supports asynchronous collaborative authoring on the Web. The CoSlide server is an extension of the Jakarta Slide WebDAV server, providing various workspaces and collaborative services through the WebDAV protocol. The CoSlide server supports workspaces for storing and sharing information of various users, and provides environment for effective collaborative authoring. Actual collaboration activities are performed through a collaboration client software which provides collaboration services along with the CoSlide server. In this paper, we describe the development of the CoSpace client which operates in association with the CoSlide server, presenting effective collaborative environment. The CoSpace client provides user interfaces for accessing and controlling the resources of each workspace on the CoSlide server. In particular, CoSpace provides the facility to launch an authoring application from its workspace view, automatic locking, and downloading the content to be edited, and resource movement using mouse drag & drop.
