Application sharing for collaborative works make multiple participants to be capable of collaborative developments through sharing development tools and applications which is distributed to various system without spatial restriction. However, applying legacy application sharing to CSCW based virtual environment has a problem because it dont consider 3D space and it disturbs the harmonic interaction of participants. In this study, we designed application sharing system for collaborative works in 3D virtual environment to share application effectively on collaborative virtual environment. The designed application sharing system for collaborative works in 3D virtual environment consist of application sharing manager, group manager and communication manager. This system is able to perceive event of 3D space about application of participant on 3D virtual environment by agent which moves to participant sites and get an ordered events and conflict among participants through scheduling. Therefore, designed application sharing system for collaborative work in 3D virtual environment can support efficient collaborative works and improve reusability of legacy application through using easily legacy application in 3D virtual environment when CSCW application development for virtual environments.

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.

Application sharing is the ability to use existing applications, such as Excel or MS-Word, during a group session without modification. In this paper, we present the design and implementation of an application sharing system, called ShareIt, which enable users to share arbitrary MS-Windows applications under the Win 3.1/95/NT and X window system, and evaluation of the system performance. To share an application, the image of the application window is captured and transmitted to other sites. With the use of the window capturing method, ShareIt allows any MS-Windows application to be shared regardless of not only the window systems but also the version-up of window systems.

The current network environment is composed of heterogeneous H/W and S/W resources. Integrating CSCW applications in such heterogeneous environments is highly complex. This paper describes the design and implementation of ASS (application sharing server) which supprot sharing of a single application between different operating systems. The ASS supports cooperative work among user group using its own window system (X-windwo or MS-windwos). We adopted improved managing heavy-weight data. ASS also provides development environment for vaious groupware application.

Purpose: This study is to identify the effect of organizational characteristics on knowledge sharing in a general hospital nurses. Method: The objects of this study were 358 nurses who had worked in a general Hospital. Data were collected from May, 3rd to May, 10th in 2004 through questionnaire. Five structured Instruments were used to collect the data. Result: The knowledge sharing of nurses was the positive correlation with openness of communication, learning orientation, the support of director of nursing department, and application of information technology(r=.431${\sim}$.611, p=.000). The degree of nurse's knowledge sharing showed a significant difference according to nurses' education level, duration of working, duty shift, working field, position in Hospital(p=.05). Openness of communication appeared into a most important predictor in knowledge sharing of Nurses, and then was learning orientation, the support of director of nursing department, application of information technology in order(p=.000). All of these variables explained 55.1% of knowledge sharing of nurses. Conclusion: To increase knowledge sharing of nurses, nursing organization will have to make up organization culture of opening communication and learning orientation of nurse, promote up the support of director of nursing department and application of information technology.

Traditionally, a domestic construction industry has recognized the relationship between a primary contractor and a subcontractor as a subordinated trade connection. To improve this unfair connection, the primary contractor and subcontractor's relationship must be recognized as Co-Development, and a new construction circumstances are needed, too. To apply benefit sharing to this relationship for Mutual Corporation, this needs the application method which could be reflected the specific aspects such as construction production method and production organization. Therefore, this study is aimed for the suggesting of basic data for Benefit Sharing application in the domestic construction industry by researching the problems and Benefit Sharing application States.

Due to the popularity of mobile phones, Peer-to-Peer (P2P) content sharing in mobile phones is highly desirable, especially in a mobile data connection. In addition, there has been an increasing demand for content sharing applications for P2P communication in Android-based smartphones as ubiquitous mobile devices. However, due to wireless network limits, unstable characteristic and restricted storage space, mobile users confront challenges in establishing connections and sharing video frames with other users. To solve this issue, we propose an architectural design and implementation of key frame sharing application that uses Chord, a distributed lookup protocol to establish a content sharing platform for mobile devices, combined with the Chord SDK based on Android. Our proposed system enables users easily to share key information on video data in real-time over a wireless network without manual processing of devices which join or leave the group and cost associated with the 3G/4G network.

This study conducts topic modeling analysis on four electric scooter sharing platforms: Alpaca, SingSing, Kickgoing, and Beam. Using user review data, the study aims to identify key topics and issues associated with each platform, as well as uncover common themes across platforms. The analysis reveals that users primarily express concerns and preferences related to application usability, service mobility, and parking/accessibility. Additionally, each platform exhibits unique characteristics and challenges. Alpaca users generally appreciate convenience and enjoyment but express concerns about safety and service areas. SingSing faces issues with application functionality, while Kickgoing users encounter connectivity problems and device usability issues. Beam receives overall positive feedback, but users express dissatisfaction with application usability and parking. Based on these findings, scooter sharing service providers should focus on enhancing application features, stability, and expanding service coverage to meet user expectations and improve customer satisfaction. Furthermore, highlighting platform-specific strengths and providing tailored services can enhance competitiveness and foster continuous service growth and development.

IoT (Internet of Things) is a collective term referring to application services that provide information through sensors/devices connected to the internet. The real world application of IoT is expanding fast along with growing number of sensors/devices. However, since IoT application relies on vertical combination of sensors/devices networks, information sharing within IoT services remains unresolved challenge. Consequently, IoT sensors/devices demand high construction and maintenance costs, rendering the creation of new IoT services potentially expensive. One solution is to launch an IoT open market for information sharing similar to that of App Store for smart-phones. Doing so will efficiently allow novel IoT services to emerge across various industries, because developers can purchase licenses to access IoT resources directly via an open market. Sharing IoT resource information through an open market will create an echo-system conducive for easy utilization of resources and communication between IoT service providers, resource owners, and developers. This paper proposes the new business model of IoT open market for information sharing, and the requirements for ensuring security and standardization of open markets.
