The people around industrial complexes and polluted areas suffer from the many occurrences of odors, and frequently issue a request for solving the odors to their local government in charge of those areas. Recently local governments whose regions have a number of such areas have a great interest in monitoring odor occurrences and gathering air on demand. This paper proposes a system in which a user can perform real-time monitoring the values of odor and atmospheric sensors, and the management of odor sensing devices using the Internet browser. Compared to previous systems, the system has an advantage of providing the functions for controlling and managing a number of devices irregardless of the location of the user. Also, the system is built around a blackboard-based multi-process architecture, enabling the easy incorporation of a new software model to be found useful. To our experiment, users showed great satisfactions in terms of the easiness of use. Our system has been installed and operated in an area of a local government in which odors are likely to occur.

Recently, the view of value and the national consciousness are expressed in various fields because of a rapid urban expanding, enforcement of local self-government system and tendency of democratization over the whole fields of society. It is difficult to satisfy this tendency of social environment change with only existing data management system. Therefore, we would use GSIS mainly used in facility management to develop the integrated urban management system which is connected the related information to related Agency. As a result, we can expect the efficient development, maintenance-management of urban and much civil affairs. On this study, firstly, we select a study area and present a basic direction of various urban facility management system. secondly, we develop the integrated urban information system with related Agency that combined the various urban facility management. Finally, we intended of its expression. It aims to manage as far as the step which is presented a model of urban integrated management system at the study area

Road sign is one of the road attached facilities to provide conveniences to motor drivers. The setup of location information according to the related regulation and the inclusion of various attributes such as place names, route numbers, symbols, bearings, distances to the place of interest distinguish the road sign from other facilities. These features give advantages to the informationization of road sign. Presently there established about 130,000 road signs on each class of roads, and about 280 road management offices have controlled these road signs independently, but there are plethora of ineffectiveness such as the lack of consistency, recognition, connectivity, and location suitability etc. These are the major factor of confusions rather than providing conveniences, and arisen a lot of public grievances. Accordingly, in this research the road signs throughout the nation were databased and the web-GIS based road sign management system was established to ameliorate the problems reveled. Since the road sign management system we developed reflected the demands of the persons in charge and users, the management effectiveness might be enhanced and the public inconveniences will be reduced.

It is so sensitive that the matter of compensation for private possessions caused in the course of public construction planning is very important. Especially, more logical planning is necessary when the dam be constructed, because it is mainly controlled by the surface of water, and if that planning is made public, artificial change is occurred in land use in that area for the purpose of rising the compensation. In this study, the plan for the application of aerial photo based ortho image was drew up for solving these problems and for the rational, rapid compensation. Ortho image was made by aerial photo, used as reading material for the change in land use. The modeling of drainage basin, came under the planning surface of water, and the 3D simulation were performed for the scene analysis, the change understanding in land use for a lot number in a certain period by overlapping the digital image, the digital land registration map, and the digital topography map as well as the analysis of the admitted land followed by the height of reservoir water.

Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16 MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with two complete blood count analyzers (Sysmex WE-8000 and Coulter STKS) for unidirectional data transmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology.

It is anticipated that the introduction of ICT to street-level welfare administration will smoothen communication processes between frontline officials and recipients by intensifying welfare information sharing and distribution. However, through a case study of ICT-mediated street-level welfare administration in South Korea, this article claims that ICT can deteriorate frontline official-recipient relationship into more distrustful and disempowered directions. This study demonstrates that ICT tends to replace face-to-face rapport building between officials and recipients with mechanical checking and complaining processes. ICT-based welfare administration can also disempower the autonomous interactions of street-level actors by surveiling every working step of frontline officials and the daily lives of recipients. Through an investigation into street-level bureaucracy in an information society, this study criticizes the dehumanization tendency of ICT-mediated human services and raises a question in the roseate vision on social welfare informatization.

As artificial intelligence develops, AI chatbot systems are actively taking place. For example, in public institutions, the use of chatbots is expanding to work assistance and professional knowledge services in civil complaints and administration, and private companies are using chatbots for interactive customer response services. In this study, we propose a scenario-based AI voice chatbot system to reduce museum operating costs and provide interactive guidance services to visitors. The implemented voice chatbot system consists of a watcher object that detects the user's voice by monitoring a specific directory in real-time, and an event handler object that outputs AI's response voice by performing inference by model sequentially when a voice file is created. And Including a function to prevent duplication using thread and a deque, GPU operations are not duplicated during inference in a single GPU environment.
