  • According to the recent development of the ubiquitous computing environment, the use of spatio-temporal data from sensors with GPS is increasing, and studies on the Semantic Sensor Web using spatio-temporal data for providing different kinds of services are being actively conducted. Especially, the W3C developed the SSNO(Semantic Sensor Network Ontology) which uses sensor-related standards such as the SWE(Sensor Web Enablement) of OGC and defines classes and properties for expressing sensor data. Since these studies are available for the query processing about non-spatio-temporal sensor data, it is hard to apply them to spatio-temporal sensor data processing which uses spatio-temporal data types and operators. Therefore, in this paper, we developed the SWE based on SSNO which supports the spatio-temporal sensor data types and operators expanding spatial data types and operators in "OpenGIS Simple Feature Specification for SQL" by OGC. The system receives SensorML(Sensor Model Language) and O&M (Observations and Measurements) Schema and converts the data into SSNO. It also performs the efficient query processing which supports spatio-temporal operators and reasoning rules. In addition, we have proved that this system can be utilized for the web service by applying it to a virtual scenario.

  • Aus kommunikativer Hinsicht wird die Textsorte 'Rede' als appellierende-persuative Textsorte charakterisiert, die eine bestimmte Aufbaustrukutur hat. Das klassische Schema der Rede setzt sich aus Einleitung, $Erz\"{a}hlung$, Beweis und $Schlu{\ss}$ zusammen. $Erz\"{a}hlung$ und Beweis, die sich in der Mitte des ganzen Textes befinden, sind verbunden mit einem Appell an die Vemunft und haben ein intellektuelles Wirkziel. Im Gegensatz dazu beabsichtigen Einleitung und $Schlu\ss$ jeweils als erster und letzter Redeteil das Erzeugen einer sanften oder heftigen Emotion. In dieser Arbeit stellt sich es in drei Textanalysen heraus, $da\ss$ die Einleitung darauf abzielt, die $Zuh\"{o}rer$ wohlwollend, aufmerksam und gelehrig zu machen, und $da\ss$ der $Schlu\ss$ darauf abzielt, die $Zuh\"{o}rer$ wohlwollend, gelehrig zu machen und zum Handeln zu ermuntern. Das Wohlwollen wird dadurch gewonnen, wenn der Redner die Zuhorer lobt oder ihren Ehrgeiz anregt, wenn der Redner den $Zuh\"{o}rern\;Ha{$\ss}$, Zorn, $Mi{\ss}gunst$ gegen den Gegner $einfl\"{o}{\ss}t$, indem er $\"{u}ber$ die schlechten Eigenschaften seines Gegners spricht, oder wenn der Redner den $Zuh\"{o}rern$ Liebe, Gunst und Mitleid $f\"{u}r$ sich selbst $einfl\"{o}{\ss}t$, indem er Dank, Freude und Bedauern usw. ausspricht oder den $Zuh\"{o}rern$ seine eingenen Tugenden, seinen Gerechtigkeitssinn, $W\"{u}rde$, Verdienste, Wohlhaben und Vertrauen zeigt. Die Aufmerksamkeit wird geweckt, wenn der Redner angesehene oder $m\"{a}chtige$ Personen in den Vordergrund stellt, wenn er zeigt, $da\ss\;er\;f\"{u}r$ das allgemeine Wohl $pl\"{a}diert$, wenn er ein Wertargument oder ein plausibles Argument benutzt, wenn er etwas Neues bespricht, oder wenn er letztendlich $ank\"{u}ndigt$, zur Sache zu kommen. Der Wille, sich belehren zu lassen, wird geweckt, wenn das vorher Gesagte anhand der Hauptpunkten und in aller $K\"{u}rze\;aufgez\"{a}hlt$ wird, um es den $Zuh\"{o}rern\;eine\;Erinnerung\;zur\"{u}ckzurufen$. Ermuterung zum Handeln wird geschaffen, wenn der Redner seine $W\"{u}nsche$ und Erwartungen usw. ausspricht. $Au{\ss}erdem$ sind rhetorische Mittel wie Ironie, rhetorische Fragen, Antithese, Wiederholung, Parallelismus, Klimax, Correctio, Metapher, Vokativ, Anspielung, Einschub, Hyperbel, $Aufz\"{a}hlung$, Chiasmus, Ellipse usw. $f\"{u}r\;das\;Gef\"{u}ge$ der Rede von Bedeutung. Sie dienen vor allem dem Zweck, den $Zuh\"{o}rern$ den Redeinhalt anschaulich, spannend und eindringlich darzubieten und damit die Wirkung der Aussage zu steigern.

  • In this paper, we implement an automated composition system of web services using hybrid techniques that merge the benefit of BPEL techniques, with the advantage of OWL-S, BPEL techniques have practical capabilities that fulfil the needs of the business environment such as fault handling and transaction management. However, the main shortcoming of these techniques is the static composition approach, where the service selection and flow management are done a priori and manually. In contrast, OWL-S techniques use ontologies to provide a mechanism to describe the web services functionality in machine-understandable form, making it possible to discover, and integrate web services automatically. This allows for the dynamic integration of compatible web services, possibly discovered at run time, into the composition schema. However, the development of these approaches is still in its infancy and has been largely detached from the BPEL composition effort. In this work, we describe the design of the SemanticBPEL architecture that is a hybrid system of BPEL4WS and OWL-S, and propose algorithms for web service search and integration. In particular, the SemanticBPEL has been implemented based on the open source tools. The proposed system is compared with existing BPEL systems by functional analysis. These comparisions show that our system outperforms existing systems.

  • Nowadays, XML has been favored by many companies internally and externally as a means of sharing and distributing data. there are many researches and systems for modeling and storing XML documents by an object-oriented method as for the method of saving and managing web-based multimedia document more easily. The representative tool for the object-oriented modeling of XML documents is UML (Unified Modeling Language). UML at the beginning was used as the integrated methodology for software development, but now it is used more frequently as the modeling language of various objects. Currently, UML supports various diagrams for object-oriented analysis and design like class diagram and is widely used as a tool of creating various database schema and object-oriented codes from them. This paper proposes an Efficinet Query Modelling of XML-GL using the UML class diagram and OCL for searching XML document which its application scope is widely extended due to the increased use of WWW and its flexible and open nature. In order to accomplish this, we propose the modeling rules and algorithm that map XML-GL. which has the modeling function for XML document and DTD and the graphical query function about that. In order to describe precisely about the constraint of model component, it is defined by OCL (Object Constraint Language). By using proposed technique creates a query for the XML document of holding various properties of object-oriented model by modeling the XML-GL query from XML document, XML DTD, and XML query while using the class diagram of UML. By converting, saving and managing XML document visually into the object-oriented graphic data model, user can prepare the base that can express the search and query on XML document intuitively and visually. As compared to existing XML-based query languages, it has various object-oriented characteristics and uses the UML notation that is widely used as object modeling tool. Hence, user can construct graphical and intuitive queries on XML-based web document without learning a new query language. By using the same modeling tool, UML class diagram on XML document content, query syntax and semantics, it allows consistently performing all the processes such as searching and saving XML document from/to object-oriented database.

  • The IHO S-100 is a standard on the universal hydorgraphic data model for supporting information services that integrate various data in maritime and provide proper information for safety of vessels. The S-100 is used to develop S-10x product specifications which are standards on guideline for creation and delivery of specific data set in maritime. The product specification for feature-based data such as ENC(Electronic Navigational Chart) data includes a feature catalogue that describes characteristics of features in that feature-based data. The feature catalogue is developed by domain experts with knowledge on data of the target domain. However, it is not feasible to develop a feature catalogue according to the XML schema by manual. In the IHO TSMAD committee meeting, needs of developing technology on building feature catalogue has been discussed. Therefore, we present a feature catalogue builder that is a GUI(Graphic User Interface) system supporting domain experts to build feature catalogues in XML. The feature catalogue builder is developed to connect with the FCD(Feature Concept Dictionary) register in the IHO(International Hydrographic Organization) GI(Geographic Information) registry. Also, it supports domain experts to select proper feature items based on the relationships between register items.

  • In constructing projects, there exist various kinds of work interferences, which cause a delay of the outset and completion of planned schedule because of some attributions, such as variability, uncertainty and complexity, and so schedule delay has been treated as a natural phenomenon. To reduce or prevent the schedule delay, a constant confirmation of schedule delay and a preparation of counter plans for finding out the cause structure of schedule delay should have been done. However, all this time the research has been mostly done on the calculation method or claim cases of schedule delay, and the range of analysis method of the cause structure of schedule delay has been multifarious from industrial views to views of specific work. Moreover, the classifying system and analysis method did not consider the trait, which cause the schedule delay, in constructing projects. For this reason, it is difficult to compare the cause of delay factors of the projects and to understand the effect of schedule delay by each factor. This paper restricts the range of the cause analysis of schedule delay to the field of site management in the projects and divides the cause structure of schedule delay into the cause objects and cause attributes of schedule delay according to the input elements. The system of classifying causes of schedule delay is examined by interviews with experts and questionnaire. Additionally, this paper analyzes the attributes of cause attributes and cause subjects and presents the analysis method and procedure of schedule delay with the application of VSM.

  • In this paper we present an integrated design methodology for relational database based on object-oriented analysis and design. The integrated design methodology is based on business profile and has six phases. In the first phase, business use cases are identified and described by macroactivity diagrams and then the macroactivity diagrams are transformed to detailed business activity diagrams by using objects, object flows and business worker's responsibilities. In the third phase, the detailed business activity diagrams are transformed to business class diagrams that describe the static structure of the entire business system based on detailed business activity diagrams. In the four phase, the business class diagrams are transformed to class diagrams that represent the initial conceptual model of the target relational database. In the five phase, we add additional transformations on the class diagrams with generalization and specialization of associations, roles, activities, additional classes and redundant associations. Eventually, the final class diagrams are transformed to relational database schema. The methodology presented in this paper by applying that proposal for organic connection between object-oriented analysis and design methodology and relational database design methodology. And it will be able to deal with integration management. By the integrated design methodology, we can make more easily software systems based on relational database. In the case study, proposal integrated design methodology applied for a visa issuing system.

  • In this paper, we developed a big data platform to store, process, and analyze effectively on such education longitudinal study data. And it was applied to the Seoul Education Longitudinal Study(SELS) to confirm its usefulness. The developed platform consists of data preprocessing unit and data analysis unit. The data preprocessing unit 1) masking, 2) converts each item into a factor 3) normalizes / creates dummy variables 4) data derivation, and 5) data warehousing. The data analysis unit consists of OLAP and data mining(DM). In the multidimensional analysis, OLAP is performed after selecting a measure and designing a schema. The DM process involves variable selection, research model selection, data modification, parameter tuning, model training, model evaluation, and interpretation of the results. The data warehouse created through the preprocessing process on this platform can be shared by various researchers, and the continuous accumulation of data sets makes further analysis easier for subsequent researchers. In addition, policy-makers can access the SELS data warehouse directly and analyze it online through multi-dimensional analysis, enabling scientific decision making. To prove the usefulness of the developed platform, SELS data was built on the platform and OLAP and DM were performed by selecting the mathematics academic achievement as a measure, and various factors affecting the measurements were analyzed using DM techniques. This enabled us to quickly and effectively derive implications for data-based education policies.

  • In this paper, a traffic adaptive sleep based medium access control (TAS-MAC) protocol for wireless sensor networks (WSNs) is proposed. The protocol aims for WSNs which consist of clustered sensor nodes and is based on TDMA-like schema. It is a typical schedule based mechanism which is adopted in previous protocols such as LEACH and Bit-Map Assisted MAC. The proposed MAC, however, considers unexpected long silent period in which sensor nodes have no data input and events do not happen in monitoring environment. With the simple traffic measurement, the TAS-MAC eliminates scheduling phases consuming energy in previous centralized approaches. A frame structure of the protocol includes three periods, investigation (I), transmission (T), and sleep-period (S). Through the I-period, TAS-MAC aggregates current traffic information from each end node and dynamically decide the length of sleep period to avoid energy waste in long silent period. In spite of the energy efficiency of this approach, the delay of data might increase. Thus, we propose an advanced version of TAS-MAC as well, each node in cluster sends one or more data packets to cluster head during the T-period of a frame. Through simulation, the performance in terms of energy consumption and transmission delay is evaluated. By comparing to BMA-MAC, the results indicate the proposed protocol is more energy efficient with tolerable expense in latency, especially in variable traffic situation.
