Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

As the social distance has been strengthened by the COVID-19 Pandemics, telecommuting has spread, and government agencies have also begun telecommuting since March and are still maintaining a certain level. The Government's remote work service, Government Virtual Private Network (GVPN), which is essential to telecommuting of government agencies, is expected to cause a number of problems with the rapid increase in users in a short period of time. Therefore, a survey and statistical analysis were conducted to analyze the impact of the quality factors of GVPN on the users' satisfaction to the public officials of the government departments who are directly using it, and based on these results, we intend to derive the implications necessary for the improvement of GVPN for remote work in preparation for the full-fledged spread of the non-contact era.

The Korean central government has been investing a lot of efforts to promote performance of local governments. For example, the Ministry of Public Administration and Security (MOPAS) supported the local governments to develop and provide with a 'balanced score card' and a 'customer satisfaction innovation. ' Many other central ministries also conducted individual evaluations for local governments in their substantive policy areas. These evaluation systems of 78 appraisals for local governments conducted by the MOPAS and other ministries had made the local governments to work harder. However, most local governments have appealed their 'reform fatigue' caused by the overlapping evaluation systems. In this context, the MOPAS initiated merging the evaluations into a co-evaluation system under the new Government Performance Evaluation Act of 2006. In this process of introduction of new evaluation system, there are two significant movements. Firstly, as Korean Government has strong information technology, MOPAS has developed 'Virtual Policy Studio (VPS)' which evaluates the performance of each local government with on line. In other words, in the co-evaluation system for local government performance most evaluation steps are implemented by computer and Internet. So most stakeholder can access and work on the VPS in real time when they want to. And the other thing is that cooperation among stakeholders has been occurred in the co-evaluation system. Furthurmore the cooperative governance is systemized and sustain for a long time because MOPAS made IT based co-evaluation system. Therefore this paper intends to illustrate the process of introduction of VPS, main process of co-evaluation system based on VPS and analyze collaborative governance of the co-evaluation system.

We live now in information society. High-tech communication technique of information came up to our daily life thoroughly. Then, what will happen to change the field of architecture in information society\ulcorner This study realized architecture in virtual reality by choosing technique in virtual reality that was able to alternate architecture in reality. The result of this study: 1. We promoted some shopping malls by making use of 'an active world' that is one of the virtual reality programs. As a result, we could know that we were able to find out goods faster than reality economically and purchase them in virtual reality. 2. There are many fields that we can adapt the architecture in virtual reality beside the shopping malls. For example, they can be a museum, an art gallery, and educational facility, a movie theater, a government and public office, and a recreation facility. 3. The architecture in virtual reality will cause to change our lifestyles and environments and to coexist architecture in reality.

The outbreak of the Covid 19 increased the interest on the 'Virtual Tourism. In this research the key word related to "Virtual Tourism" was collected through the search engine and was analyzed through the data mining method such as Log-odds ratio, Frequency, and network analysis. It is clear that the information and communication dependency increased in the field of "Virtual Tourism" after Covid 19 and also the trend have changed from "securement of the contents diversity" to "project related to economic recovery." Since the demands for the "Virtual Reality" such as metaverse is increasing, there should be an economic and circular structure in which the government establishing a related policy and the funding plan based on the research, local government and the private companies planning and producing discriminate contents focusing on AISAS(Attension, Interest, Search, Action, Share) aand the research institutions and universities developing, applying, assessing and commercializing the technology.

Since January 2009, Seoul Metro Government(SMG) is operating own Network RTK Systems connecting four(4) GNSS Reference Stations which are installed inside Seoul Metro City area. SMG is currently providing VRS data service via wireless internet for Network-RTK and RINEX data observed from GNSS Reference Stations. This paper will discuss utilization of data available from SMG Network-RTK System for various applications, and present the test results on practicalities of Virtual RINEX data. For the utilization of data available from SMG Network- RTK system, 1)NTRIP data delivery of GNSS realtime observables streaming and converting to RINEX at receiving side, 2) monitoring deformation of bulky structures using GNSS observation were discussed. In addition to those discussion, 3) broadcasting VRS correction data for job site via radio modem after acquiring such correction data on-line using NTRIP based GNSS Internet Radio from SMG Network-RTK System were introduced. For the test results on practicalities of Virtual RINEX data, 1) the post-processing results of the GNSS observation data on a certain point with GNSS Reference Station data have been compared to the post-processing results of Virtual RINEX data on the same point generated from SMG Network-RTK System, and 2) VRS RTK positioning results for a certain point and post-processing results of Virtual RINEX data for the point were compared. The results showed only a few mm difference, and the high possibility for using Virtual RINEX data for post-processing applications.

The purpose of this study is to present the application of Information and Communication Technology(ICT) during the 4th Industrial Revolution for the efficient implementation of government emergency preparedness policies. Brainstorming by experts categorized the government's emergency preparedness policies into 4 types and 12 detailed tasks. Classification results were used by AHP(Analytic Hierarchy Process) to analyze relative importance and priorities. The AHP survey found that strengthening crisis management responsiveness was the most important detailed task. Artificial Intelligence(AI), Internet of Things(IoT), Unmanned Autonomy System, Virtual Reality(VR), and Augmented Reality(AR) were presented as major information and communication technology(ICT) for the efficient execution of detailed tasks.

A VPN is a private network that uses a public network to connect remote sites or users together. As its popularity grows, companies, organization and even the government turned to it as a means of extending their own networks. To setup a Virtual Private a proper IP VPN Architecture must first be selected. In this paper, the types of IP Virtual Private Network Architecture like the MPLS-Based, IPSec-Based and the SSL/TLS-Based are discussed and compared. The comparison may serve as a guide for selecting the proper IP Virtual Private Network Architecture that is suitable for the company's needs.
