In this era of knowledge economy, a variety of virtual communities are proliferating for the purpose of knowledge creation and utilization. Since the voluntary contributions of members are the essential source of knowledge, member turnover can have significant implications on the survival and success of virtual communities. However, there is a dearth of research on the effect of membership turnover and even the method of measurement for membership turnover is left unclear in virtual communities. In a traditional context, membership turnover is calculated as the ratio of the number of departing members to the average number of members for a given time period. In virtual communities, while the influx of newcomers can be clearly measured, the magnitude of departure is elusive since explicit withdrawals are seldom executed. In addition, there doesn't exist a common way to determine the average number of community members who return and contribute intermittently at will. This study initially examines the limitations in applying the concept of traditional turnover to virtual communities, and proposes five membership fluidity measures based on a preliminary analysis of editing behaviors of 2,978 featured articles in English Wikipedia. Subsequently, this work investigates the relationships between three selected membership fluidity measures and group collaboration performance, reflecting a moderating effect dependent on work characteristic. We obtained the following results: First, membership turnover relates to collaboration efficiency in a right-shortened U-shaped manner, with a moderating effect from work characteristic; given the same turnover rate, the promotion likelihood for a more professional task is lower than that for a less professional task, and the likelihood difference diminishes as the turnover rate increases. Second, contribution period relates to collaboration efficiency in a left-shortened U-shaped manner, with a moderating effect from work characteristic; the marginal performance change per unit change of contribution period is greater for a less professional task. Third, the number of new participants per month relates to collaboration efficiency in a left-shortened reversed U-shaped manner, for which the moderating effect from work characteristic appears to be insignificant.

The business management system is a standardized system commonly used by government agencies and is a major tool that remains in the work process and decision-making of government agencies. Production of document-type records is mainly focused on approval documents, so it does not cover various types of records. In a changing environment such as the production of new digital types of records, the emergence of various collaboration software and work systems, and remote work, it is necessary to think about the direction the government work management system will go. This study investigates business systems and utilization methods of competitive companies, analyzes the usage status of On-Nara 2.0, a government business management system, and conducts interviews with business managers. And the purpose is to analyze what kind of difference there is. In addition, we would like to suggest improvement functions and policy directions to respond to digital innovation and improve job accountability and efficiency.

The World Wide Web (Web) is one of the most popular internet tool on now, In this reason most of common user, they understand the Web is internet and Web content is also important issues on this side. However, commonly Web content created by one of Web content creator and sometime they refer the another document and link. In these kinds of environments cause tile delivery of incorrect information or linking to another Web user. There are lots of way to protect the incorrect information deliveries to Web user and the most famous one is Computer Supported Cooperation Work (CSCW). This supports the multi-user environment on single system environment, but this needs more additional things in the current internet environment Current internet defined as distributed information network not tile traditional client-server environment. Specially, Intranet environments need to support the heterogeneous system environment like several Rinds of database, systems like PC, Mac and UNIX workstation, and etc. In this reason, we need collaboration and this would serve the common user interface to all of Web user. In these paper, we review the current concept of CSCW and grouoware that are major concept of collaboration and definition, classification and problem analysis of the collaboration. Finally, we suggest the construction method of collaboration environment for Web.

An information system in a construction project has been typically used for drawing, document management, and administration process. And it has limitations to support real-time communication and collaboration among project stakeholders. The objective of this research is to improve communication, information share, and task management by developing a collaboration platform among project stakeholders supporting various communication methods and contents. The platform developed in this research, named as CCP, aims to support communication and collaboration related activities beyond the scope of legacy systems at construction sites. CCP was validated through pilot test and user survey, and it was found to be very helpful for sharing and distributing information, tracking and recording, and improving a user's work capability.

In this paper, the business process was easily modeled by distinguishing between the business process and work logic. Based on this model, B2Bi collaboration Workflow modeling tool, which facilitates collaboration, was designed and implemented. The collaboration workflow modeling tool consists of 3 components; business process modeling tool, execution engine and monitoring tool. First, a business process modeling tool is used to build a process map that reflects the business logic of an application in a quick and accurate manner. Second an execution engine provides a real-time execution environment for business process instance. Third, a monitoring tool provides a real-time monitoring function for the business process that is in operation at the time. In addition to this, it supports flexibility and expandability based on XML and J2EE for the linkage with the legacy system that was used previously, and suggests a solution for a new corporate strategy and operation.

In this paper, we have tfesigned and ihlplemented ACE(Application sharing Collaboration Engine) which is pessible an application sharing to collaborate among peoples who are geographically dispersed. The application sharing is a technology whereby two or more users collaborate to share the output of single application running on one computer system to the other users, and to provide input to the applications. We defined ASO(Applicatio!1 Sharing Object) object and its behavior to share applications in real time and ACE processes a sharing using ASO object among the distributed systems. ASO is classified into activateASO, updateASO, inputASO, and controlASO. The each ASO's behavior involves both events which occur at specific moments such as keystrokes and mouse clicks and more persistent status which can be observed at any time such as the image on the screen. The implemented ACE can be applied to the data conferencing, distance education, and project collaboration for engineer in distributed environments.

Mule Bone (1931), Zora Neale Hurston's collaboration with Langston Hughes, has been credited as the 'first' attempted by African Americans to create black folk comedy. The proposed research is driven from a question to the recent scholarship's tacit consent on such historic importance imposed on the play. This paper suggests a possibility that De Turkey and De Law (1930), Hurston's edition of the collaboration work, could be the truly first attempt in the tradition of American black folk comedy. By illuminating a series of historical moments in which Hurston first expressed her dream for writing a real black folk comedy that would be a really new departure in the African American drama, then collaborated with Hughes on the dream play project, and eventually quit the collaborationship due to artistic dispute with Hughes, this paper explains why Hughes edition Mule Bone came to remain 'unfinished' and, more importantly, fall short of Hurston's original goal and expectation from the collaboration. On the other hand, this paper sheds light on the significance of often-ignored Hurston's edition De Turkey and De Law by demonstrating how this play, compared to Mule Bone, fulfills her original idea of black folk comedy in terms of contents and themes compared with Mule Bone. Adding to the knowledge about little known behind story related to the Mule Bone controversy and the subsequent birth of the two different editions of the Hurston-Hushes collaboration project, supplementing the dearth of the related research with a critical comparison of the two editions, and discussing the validity of Hurston's edition as the real sense of black folk comedy, this paper argues for the necessity of reconsidering the origin of the mentioned genre. This paper finally concludes that De Turkey and De Law, replacing Mule Bone, deserves a right to be truly the first American black folk comedy genre in the sense that it was completed and copyrighted three months earlier than Mule Bone and that, more importantly, it cherished the original aim and artistic vision of black folk comedy Hurston first planned and expected through the collaboration with Hughes.
