Recently, National Emergency Management Agency constructs integrated information system for preventing national earthquake based on underground information. In the past, there are numerous difficulties in construction and management of underground information, because underground information is constructed by each management agency. But a link and application of underground information are available because of government 3.0. This study shows the integrated information system for preventing national earthquake based on real-time link of underground information. The integrated information system for preventing national earthquake developed in this study consists of boring information input modules, underground information search/analysis modules based on V-world tile map, user authority management modules, user management modules and real-time liaison interface modules. Also, this study proposes enhancement plan to construct integrated information system for preventing national earthquake stably and strongly. Stability test conduct on stability of data storage, system stability and consistency of processing speed test results show stability of the integrated information system for preventing national earthquake is high.

Recently, semantic search techniques which are based on information space as consisting of nonambiguous, non-redundant, formal pieces of ontological knowledge have been developed so that users do exploit large knowledge bases. The purpose of the study is to design more user-friendly and smarter retrieval interface based on ontological analysis, which can provide more precise information by reducing semantic ambiguity or more rich linked information based on well-defined relationships. Therefore, this study, first of all, focuses on ontological analysis on researcher information as selecting descriptive elements, defining classes and properties of descriptive elements, and identifying relationships between the properties and their restriction between relationships. Next, the study designs the prototypical retrieval interface based on ontology-based representation, which supports to semantic searching and browsing regarding researchers as a full-fledged domain. On the proposed retrieval interface, users can search various facts for researcher information such as research outputs or the personal information, or carrier history and browse the social connection of the researchers such as researcher group that is lecturing or researching on the same subject or involving in the same intellectual communication.

The description of this paper was made putting the emphasis on CIM Interface configuration with a college policy program as the center whether it is suitable or not for a college promotion. CIM Interface technique for a college promotion is an expression method by visual requirements. Alternatives to a college promotion turned up which are depending on Contents, Image, Marketing strategies by visual elements. The application of consumer contents to give users information did the role of a channel inducing the users to join. Besides, an information designing enabled the information structure to be a visual expression by being grafted on content consistency. First above all, the implementation policy of such systematical formation could be found through University Identity Program-IMC useful as a branding strategy of a college promotion. Like this, a methodology which is able to increase the efficiency of college promotion through a process and a connection was established.

In this paper, we propose a computationally efficient method detecting the P300 wave for brain-machine interface. Electrophysiological researches have shown that the P300 wave's potential is decreased when human intention matches visual stimulation. Motivated by this fact, we can infer human intention for brain-machine interface by detecting the P300 wave's potential decrease. The P300 wave is recorded from EEG(electroencephalogram) electrodes attached on human brain skull after giving alphabetical stimulation. To detect the potential decrease in P300, firstly we statistically model the P300 wave's negative potential. Then we infer human intention based on maximum likelihood estimation. The proposed method was evaluated on the data recorded from three healthy human subjects. The method achieved an averaging accuracy of 98% from subject k, 90% from subject j and 79.8% from subject h.

Currently broadcasting and telecommunication has integrated, And IPTV Service has appeared who called TPS(Triple Play Service) which integrated with broadcasting, telecommunication and Phone Service. IPTV provide broadcasting service and VOD(Video on Demand) service, and it must be satisfied digital content security. For this condition, IPTV Forum working on standardization of interface for digital content security. The Security solution for broadcasting and VOD are CAS(Conditional Access System) and DRM(Digital Rights Management). But these solutions manufactured by many vendors, so there is no inter-operablity. And after finished standardization of interface for CAS and DRM system, the problem of inter-operability with them will be issued. For this reason, Rights management system which possible to operate independently with platform is necessary. In this paper, To protect multimedia digital content, we designed and implemented Conditional Access Management System.

GIS is a powerful toolbox in managing spatial data associated with attribute data. However GIS is short of spatial analysis function and graphic user interface(GUI) function in dealing with dynamic planning problems. Decision Support Systems(DSS) make up for the shortage of GIS by providing GUI function, modeling function and database function. Spatial Decision Support Systems(SDSS), a new kind of DSS, incorporate display function, basic spatial analysis function and manipulation function of spatial data and attribute data of GIS and GUI function, modeling function and database function of DSS in dealing with spatial planning problems. Planning Support Systems(PSS) add more advanced spatial analysis function and intertemporal function to the functions of SDSS. This study focuses on the modeling of a PSS for capacity expansion of water-distribution network depending upon land use planning by using GIS, value engineering(VE) and life cycle costing(LCC). The PSS shows a guideline about the investment of water-distribution networks related to urban growth management through generating certain numbers of dynamic alternatives to supply the amount of water caused by land use planning.

Current virtual game interfaces cannot comprehend our metaphor, cannot reflect on our natural behavior aspect, cannot make us immerse into a game, and makes a barrier between virtual game space and our real behavior. It is very meaningful issue to use real objects tightly related to human-being's behaviors or reactions for interacting with game applications. Interactive Augmented Reality interfaces may augment users' perception of the real world by adding virtual information to it. We attempted an experiment on camera-based non-marker interface for online TCG application. This experiment uses real TCG cards which are recognized by our two phases Image KeyPoint Extraction/Matching Algorithm. These initiative experiments not only enlarge immersion and reality to the game, but also make real and virtual world seamless.

The demand of MOST interface module is increasing with car-multimedia network system. MOST devices consist of INIC part which controls MOST network and EHC part which is used by user. The efficient data communication between EHC and INIC demands implementation of a proper device driver. This paper presents a design method for I2C communication driver which is used for transmitting control messages between nodes of MOST network. For effetive I2C communication, we design driver with NetService API. For testing the experiment, we use the MOST audio interface deivce for porting driver sources and will develop various driver on MOST device based OS.

Recently, with the development of mobile communication technologies such as 5G, interest in oscilloscope technology based on high bandwidth and user-friendly UI is increasing. In this paper, we proposed a Python-based UI(user interface) SW for a high-bandwidth digital oscilloscope in connection with the study of a 13GHz band digital oscilloscope system. The proposed UI SW is designed not only to be executed integrally with the oscilloscope, but also to be run on a separate PC or laptop cooperating with the instrument through WiFi communication. Functions of the UI SW consists of displaying and analyzing signal data, storing signal data in an external storage device, generating test signal data, and reconfiguring the toolbar. Finally, we have shown that the proposed digital oscilloscope system operates normally by interworking test with the signal generator.
