  • The purpose of this research is to determine how the present use of Geographic Information Systems (GISs) can be improved for ill-structured problems in planning and design, While information-oriented GIS technology has proven useful for routine and administrative problems, it is not yet capable of providing information and knowledge interactively within a problem solving process that can be characterized as "ill-structured." This suggests that GIS technology must be embedded wi thin a large problem solving process for ill-structured problems. The hypothesis of this research is that implementation of conceptualization-oriented Spatial Decision Support Systems(SDSSs) will significantly improve the use of GIS technology for ill-structured problems.

  • The purpose of this study was to identify the effect of structured information provided on knowledge and self-care behavior. The subjects of this study were both hospitalized patients and outpatients in K university hospital. The instrument use for this study were the knowledge assessment tool and self-care behavior assessment tool by Eom Soon-Ja(1998) and they were modified for liver cirrhosis patients. The data were analyzed by t-test, Chi-square test, Pearson correlation coefficients using SAS program. The results of this study were as follows. The experimental group which had received structured information provided showed greater increased knowledge of liver cirrhosis(P=.001). The experimental group which had received the structured information provided indicated increased self-care performance rate, especially after information about diet(P=.001), activity and bed rest(P=.001), drug therapy and visiting the hospital(P=.001), prevention of a complication and observation(P=.001). In conclusion, structured information provided showed increased in the degree of knowledge and self-care behavior, so information showing is an effective nursing intervention. It is much needed to employ information showing for chronic patients.

  • This paper focus on the development of object-oriented model bases for Structured Modeling. For the model base organization, object modeling techniques and model typing concept which is similar to data typing concept are used. Structured modeling formalizes the notion of a definitional system as a way of dscribing models. From the object-oriented concept, a structured model can be represented as follows. Each group of similar elements(genus) is represented by a composite class. Other type of genera can be represented in a similar manner. This hierarchical class composition gives rise to an acyclic class-composition graph which corresponds with the genus graph of structured model. Nodes in this graph are instantiated to represent the elemental graph for a specific model. Taking this class composition process one step further, we aggregate the classes into higher-level composite classes which would correspond to the structured modeling notion of a module. Finally, the model itself is then represented by a composite class having attributes each of whose domain is a composite class representing one of the modules. The resulting class-composition graph represent the modular tree of the structured.

  • XML (extensible Markup Language) is selected and published as a representative standard of electronic documents by W3C (World Wide Web Consortium). The structured information can be created and also transferred in XML documents. By utilizing XML, you can express the meaningful information unit as a structure comparing existed file typed information. With structured information, you can also manage retrieve, and reposit documents. According to the above facts, in this paper, it is the purpose to design and implement XML documents repository system to reposit and retrieve using structured information of XML documents. As a model it was designed to be stored by element unit which is the basic unit of documents and was also designed to retrieve the stored XML information by structured unit. It was, especially, designed to manage and reposit the structure of various documents effectively through creating schema as to DTD(Document Type Definition) and instance.

  • Node is the semantic unit and a part of structured document. Information retrieval from structured documents offers an opportunity to go subdivided below the document level in search of relevant information, making any element in an structured document a retrievable unit. The node-based document retrieval constitutes several similarity calculating methods and the extended node retrieval method using structure information. Retrieval performance is hardly influenced by the methods for determining document similarity The extended node method outperformed the others as a whole.

  • So far, many sensors such as a structured grid pattern generator, a laser, and CCD camera to obtain 3D information have been used, but most of algorithms for a calibration are inefficient since a huge memory and experiment time are required. In this paper, the calibration algorithm of a structured grid pattern based on triangulation method is introduced to calculate 3D information in the real world. The beams generated from structured grid pattern generator established horizontally with the CCD camera are projected on the calibration plat. A CCD camera measures the intersection plane of a projected beam and an object plane. The 3D information is calculated using measured and calibration datum. This proposed method in this paper has advantages such as a memory saving and an efficient experimental time since the 3D information is obtained simply the triangulation method.

  • In this paper, we propose a new video structuring method for reconstructuring a 'structured logical video' which adds logical video information to a conventional structured video. Logical video information is composed of background, object, and situation. The proposed structured video is reconstructed in logical unit like episodes as well as in physical unit like shots. It can support many video functions and may be reusable in many video applications-video browsing, video retrieval, video editing, etc. we also present the video database management system in order to manage the proposed structured video is modeled on object-oriented concept and hierarchical structure. Also, we design and implement a video browsing and retrieval system using the proposed structured video.

  • The goal of this study is to generate a structured document which improves the performance of an information retrieval system by using thesaurus, information on relations between words (terms), and to study on the technique for searching this structured document. In order to accomplish this goal, we propose a DODI (Depth -Oriented Decomposition Index) technique for the structured document and an algorithm to search for related information efficient]y through this index technique that uses a thesaurus. We establish a storage system by which the structured document generated by this index technique is saved in a database through OpenXML and XML documents are generated through ForXML methods.

  • Visions of ubiquitous robotics and ambient intelligence involve distributing information, knowledge, computation over a wide range of servers and data storage devices located all over the world, and integrating tiny microprocessors, actuators, and sensors into everyday objects as well in order to make them smart. In this paper, we introduce our ongoing research effort aimed at realizing ubiquitous robots in an information structured space. For this, a ubiquitous space and ambient intelligent systems for a librarian robot are introduced and the RFID technology based approach for these systems is described.
