Jakarta Slide는 아파치 프로젝트 중의 하나로 개발된 WebDAV 서버로서 인터넷 통하여 다양한 콘텐츠의 비동기적인 협업 활동을 지원한다. 하지만 WebDAV 프로토콜은 사용자와 그룹을 위한 작업공간을 명시적으로 지원하지 않기 때문에, Jakarta Slide를 통하여 복잡한 협업을 수행하기는 매우 어렵다. CoSlide는 이러한 문제점을 개선하기 위하여 Jakarta Slide를 확장한 협업시스템으로서 다수의 사용자와 그룹을 위한 다양한 작업공간을 제공하여 효과적인 협업 환경을 제공한다. 협업시스템을 통하여 복잡한 협업을 보다 효과적으로 수행하기 위해서는 협업 참여자들 간에 실시간적인 통신이 원활이 이루어져야 할 필요성이 있다. 본 논문은 CoSlide 협업시스템에서 실시간 메시징을 지원하기 위한 CoJBother 메신저 클라이언트의 개발에 대하여 기술한다. 개발된 CoJBother는 협업시스템의 사용자와 그룹을 정의하기 위하여 개발된 Jabber 프로토콜을 사용하며, 또한 이를 지원하기 위하여 개발된 메신저 서버와 함께 동작한다. 사용자는 CoJBother를 통하여 협업시스템의 작업그룹에 참여하는 사용자들을 확인하고 자동적인 그룹채팅 기능을 사용함으로써 그룹 참여자들과 협업 수행을 위한 원활한 의사소통을 할 수 있다.

The purpose of this study is to investigate the influence of gamification strategies on improving participation and motivation of shared electric scooter users. To this end, this study derived the user type through the first research question of how the shared electric scooter usage behavior and pulse are, and derived user tasks and scenarios. The second research question, a shared electric kickboard app with gamification, was tested by users to see if it helps increase user participation and form motivation. As a result of the analysis, it was found that users were induced to be considerate of other users by using a combination of the motivational, relational, and self-expression strategies of gamification. Second, it was found that the use of motivation, achievement and reward, and reward visualization strategy elements promotes user's voluntary behavior. Third, through relationship, achievement, and reward strategies, users participated to create a positive culture of shared electric scooters, drawing immediate feedback, indicating that convenience has increased. In conclusion, it was found that the user helped to play a positive role in voluntary participation and motivation through the use of the shared electric kickboard service with gamification.

본 연구는 메타버스 플랫폼에서 사용자 간의 커뮤니티 사회성을 형성해 가는 과정에서 성격의 5요인이 미치는 영향에 대하여 살펴보고 상호 간에 유의미한 특성을 살펴보고자 한다. 성격 5요인의 특성으로는 신경성, 외향성, 우호성, 성실성, 개방성의 다섯 가지 요소가 있으며 이는 메타버스 가상공간에서 사용자 간의 통합 및 경쟁, 게임과 같은 시스템을 통하여 사회 형성에 많은 영향을 미칠 것이다. 성격 5요인과 반대적 성격 5요인은 메타버스 사용에서 개인의 성격을 강화하거나 약화시킬 수 있고 사용시간, 참여율, 만족도 면에서도 다른 결과를 보여줄 것이다. 소통을 중요시하는 메타버스에서 사용자의 성격에 따른 섬세한 콘텐츠 제시는 분명 더 나은 콘텐츠로 시장에 경쟁력이 있을 것이다. 본 논문에서는 메타버스의 사용이 개인의 성격에 미치는 영향을 이해하는 데 도움이 될 것이며, 메타버스 내에서 사용자 성격 5요인 성향을 정립하고 이를 통해 차세대 플랫폼 구축 및 개발에 도움이 되고자 한다.

The sharing economy has emerged as a new form of consumption pattern along with the advancement of information technology and the changes in the consumers' desires for economic spending. In a C2C-sharing economy platform, the user side and supplier side share the same assets, thereby making both sides of the market closely related. However, an information asymmetry exists within the platform that makes the players from one side reluctant to participate. This information asymmetry warrants a strategic approach for solving the fundamental "chicken and egg" problem for platform development. Motivated by this phenomenon, this study aims to analyze how the participation intentions from both sides of the platform are influenced by certain anteceding factors, such as trust, perceived risk, and perceived economic profit. Our findings show that the anteceding factors affect the participation intentions in different paths for both sides of the platform. As a managerial implication, these findings highlight the necessity of employing different approaches for each side of market development.

Recently, the web 2.0 services which appear by exponential extension of the Internet can be expressed with the changes in the quality of structural evolution and in the quantity of increasing users. The structural base is in user participational architecture, the web 2.0 services such as Blog, UCC, SNS(Social Networking Service), Mash-up, Long tail, etc. play a important role in organization of web, and grouping and searching of user participational data in web 2.0 is broadly used by folksonomy. Folksonomy is a new form that categorizes by tags, not classic taxonomy skill. it is made by user participation. Searching based on tag is now done by a simple text or a tag cloud method. But searching to consider and express the relations among each tags is imperfect yet. Thus, this paper provides the relational searching based on tags using the relational graph of tags. It should improve the trust of the searching and provide the convenience of the searching.

This study defines the integrated game experience of game users that across internal and external media of game as the transmedia enjoyment of game. This study categorizes the cases and analyze features. Game users have four types of transmedial enjoyment. The expansion type is characterized by the user's desire to solve the uncertainty, and the transmission type is characterized by the emergence of alternative play spaces. In the permeation type and the circulation type, it is observed users participate more in the content can be re-contextualized and based on real world knowledge.

The era of Web 2.0, which is the web environment that offers end user oriented web platform, has arrived. Moreover, as the interest in UCC (User Created Contents) environment increases, it is a fact that the involvement of the users in multimedia contents is increasing rapidly. When the aim of Web 2.0, i.e. active involvement of the user, is considered, the necessity and the understanding about accessibility problem of the people who have difficulties about accessing web information, such as elderly and visually handicapped people, is increasing as well. This research analyzes the problems of virtually handicapped users to access web-based UCC services, and proposes an efficient implementation plan for a web-based UCC service that enables smooth access for them. Especially, the validity of the proposed method was verified by comparing the reaction time of the visually handicapped users with that when using the existing UCC services, through the implementation of the test page according to the plan proposed in this research.

The environmental problems caused by food waste have been a steady social issue, and the severity of the problem emerged as the 2013 London Convention banned the marine emissions of waste water. The government implemented measures related to food waste, but prior studies showed that it lacked continuity and lacked strategies for each area of occurrence, and emphasized that citizens' participation is important to implement effective reduction policies. Therefore, this study proposed a food waste disposal machine through user experience analysis as a way to induce civic participation. To this end, the design development direction was outlined in this study after the pre-research and user survey stages through FGI and user journey maps. Based on this, the proposed treatment machine facilitates the frequent discharge of waste and simplifies the process of food waste in the home. In addition, the moment of direct contact between the user and waste is only the point at which the waste is released to the handler, thereby minimizing the negative experience the user has experienced.

무선 환경에서의 전자상거래가 빠르게 성장함에 따라 종단간 보안이 필요하다. 기존 WTLS를 사용하는 WPP 프로토콜에서는 종단간 사용자 안전성을 보장하고 있지 않다. 이 논문에서는 AIP 프로토콜에서 사용자와 서비스 제공자간에 종단간 안전성이 제공되는 무선 인터넷 플랫폼에 독립적인 소액지불 프로토콜을 제안한다. 또한 인증기관이 인증과정에 참여할 경우 ID 기반 공개키 암호 시스템을 적용한 세션키를 생성하여 제안 프로토콜의 안전성 및 효율성을 분석한다.

Web technology has allowed the rise of services such as blogs or YouTube that make possible the sharing of opinions, perspectives, and experiences with other users through contents. Online services that promote such sharing of information and communication are known as social media. Recently, the explosive growth of these services displays the carry-over of the natural sociality that all humans possess as social creatures. This study took an exploratory approach in investigating what influential relationships are involved in forming new relationships through sharing and participation, as sharing and participation are core keywords of social media. In order to do this, relationship formations were observed in actual usage environments with the use of the diary study method and in-depth interviews. This study sought to deduce necessary elements in relationship formations and examine the influences of weak ties on participation and sharing.
