This paper describes technical method about remote control and monitoring of local system by use internet web connection system, which connect local system and system manager works in long distance office. The local system, which will be controlled remotely have constructed with analog/digital signal acquisition device, signal control board and their software. The local systems are constructed with several electronic modules need AC or DC power supply to operate the right way. We used NI labview software to control and monitoring of local system. The computer server for remote connection are constructed with Apache web server, PHP and MySQL ODBC. The experiment for the remote control are need internet web browser which load local control software. By use of web system, we have experimented control and monitoring of local electronic module.

Web usage mining is the technique of data mining that analyzes web users' usage patterns by large web log. To use the web usage mining technique, we have to classify correctly users and users session in preprocessing, but can't classify them completely by only log files with standard web log format. To classify users and user session there are many problems like local cache, firewall, ISP, user privacy, cookey etc., but there isn't any definite method to solve the problems now. Especially local cache problem is the most difficult problem to classify user session which is used as input in web mining systems. In this paper we propose a heuristic method which solves local cache problem by using only click stream data of server side like referrer log, agent log and access log, classifies user sessions and completes session.

The purpose of this paper is to review the performance of the Green Village Project during the last 10 years, and examine the possibility of the institutionalization of a local governance. The Green Village Project was first initiated by an environmental movement group in Cheongju City, and now various actors, including Cheongju City and City Council members, public organizations, professionals etc, are participating. The project has been continuously and stably carried out for 10 years, and the participants now recognize that the project should be carried out every year. According to the analysis, the participants recognized the project as beneficial project for them on the basis of the rational choice. And the participants recognized the project as having legitimacy, and accumulating 'trust' between participants, accumulating the experiences of success. In conclusion, the sustainability and stability of the project has been strengthened, and the institutionalization possibility of the governance of the Green Village Project has been increased continuously.

The creation of new economic paradigm shift in creative economy age have influence on the characteristics of social networks and space, it leads to the formation of new relationship in space depending on social network service development. In this paper, it gives a name to 'social network resource' the power affecting these features and to find the meaning of spatial changes in the economic geography perspectives. 'Social network resource' shows the characteristics of openness, sharing, participation and cooperation, with features of encompassing all the features of local and global characteristics in space. This features are related the meaning of 'trans-locality' and can be found in the case of 'WikiSeoul.com (http:/www.wikiseoul.com)', Seoul's social knowledge sharing web platform. In particular, physical resources, human resources, information resources, and the characteristics of the relationship as a resource features was found and these features appear in space is projected to the space of social relations, it reflects the characteristics of qualitative space regarding social network resource.

In this paper, we proposed a new lazy classifier with fuzzy k-nearest neighbors approach and feature selection which is based on reconstruction error. Reconstruction error is the performance index for locally linear reconstruction. When a new query point is given, fuzzy k-nearest neighbors approach defines the local area where the local classifier is available and assigns the weighting values to the data patterns which are involved within the local area. After defining the local area and assigning the weighting value, the feature selection is carried out to reduce the dimension of the feature space. When some features are selected in terms of the reconstruction error, the local classifier which is a sort of polynomial is developed using weighted least square estimation. In addition, the experimental application covers a comparative analysis including several previously commonly encountered methods such as standard neural networks, support vector machine, linear discriminant analysis, and C4.5 trees.

In this paper, a von system which is based on current computer technologies is implemented. This von system organizes many personal computers in a local network into a configuration server, storage servers, and clients. To provide reliability, the data is stored using software RAID technology. Also, multimedia services are client-based for efficiency. The software components of this von system are the von configuration software, the von configuration service software, the von management software, and the von service software. Only the von service software runs in the client, while all the others run in the configuration server. The operating system on which the configuration server is run is the Windows NT such that the software executes like the UNIX-daemon process in the Windows NT service manager.

Debugging for application Programs running in embedded Linux systems has mostly been done remotely due to the limited resources of the target systems. The gdb, which is one of the most famous debugger in Linux systems, does not support the debugging of the child processes which is created by the fork system call in local and remote environments. Therefore, by using gdb, developers can debug the application programs that have single-process structure in local and remote environments, but they cannot debug the application programs that have multi-process structures by using gdb in remote environments. Also, although developers can debug the application programs that have multi-process structures by using gdb in local environments, it needs additional and unnecessary codings. In this paper, we presents the remote debugging scheme that can be used for debugging multi-process structured applications. The proposed scheme is implemented by using the library wrapping scheme, and also uses the conventional system components such as gdb and gdbserver.

In this paper, we proposed the adaptive local sigma filter reducing noises generated by an image sensor. The small noises generated by the image sensor are amplified by increased an analog gain and an exposure time of the image sensor together with information. And the goal of this work was the system design that is reduce the these amplified noises. Edge data are extracted by Flatness Index Map algorithm. We made the threshold adaptively changeable by the luminance average in this algorithm that extracts the edge data not in high luminance, but just low luminance. The Local Sigma Filter performed only about the edge pixel that were extracted by Flatness Index Map algorithm. To verify the performance of the designed filter, we made the Window test program. The hardware was designed with HDL language. We verified the hardware performance of Local Sigma Filter system using FPGA Demonstration board and HD image sensor, $1280{\times}720$ image size and 30 frames per second.

VNC(Virtual Network Computing) is a desktop sharing system based on the RFB(Remote Framebuffer) protocol which allows you to control a remote computer running a VNC server through a VNC client(or viewer) on a local computer. To exchange information between the two computers, VNC provides the functionality of sharing the clipboard contents. Unfortunately, the current VNC softwares support only the clipboard text contents, not providing methods for sharing the clipboard multimedia contents such as images. In this paper, we extend the RFB protocol to share the clipboard contents composed of text and images. Also, to support the developed protocol. we extend both the UltraVNC server and the JavaViewer VNC client which are free open-source softwares. Through the developed VNC softwares, users can exchange the clipboard contents including texts and images between the remote computer and the local computer.
