Purpose: As Koryo Hand Therapy is generally referenced by a manual, we made a database system to ease. Method: Using the basic theory of Koryo Hand Therapy with the System Development Life Cycle (SDLC), we tested, analyzed, designed and implemented the system and constructed a database system with MS Access according to the symptoms. Results: We constructed the database system of Handing and the symptoms of Koryo Hand Therapy in 3 parts (Basic Data Management, Disorder Therapy Management, Report) for easy management. This database system will be useful for general users to protect, promote and measure their health. The structured database system was valued on the basis of the students basic knowledge of Koryo Hand Therapy. As a result, 80% of the respondents answered that the "system is well structured", 78% that "it's convenient to search", and 87% that "it's helpful for self health management". Conclusion: These study results provides people with information on the basic treatment of symptoms for the self health protection and promotion with Koryo Hand Therapy by constructing a database.

In this paper, we describe the design and implementation of a multimedia information system integrating hypermdia, information retrieval, and DBMS technologies. We browse the information space through hypermedia link navigation and also use ad hoc queries for direct retrieval of information from the database. Both the hypermedia and the information retrieval systems are integrated into a database management system (DMBS) so that concurrent edition, update, and retrieval of documents can have the ACID properties of atomicity, consistency, isolation, and durability. We will first explain the architecture of the system and then, describe how the hypermedia system is integrated with information retrieval capability, and finally integrated with DBMS capabilities.

We discuss the characteristics of authoring tool for the lecture on demand(LOD) in a cyber university. Authoring tool will be one of the important tools for constructing LOD that gives good educational opportunities to students of cyber university. The one of characteristics in authoring tool is“Education”and“Entertainment”. The LOD system constructed with authoring tool will be impact on multimedia telecommunication, technology for constructing and searching multimedia database, GroupWare and distributing technology, etc.

In this paper, we propose the obstacle database management module for obstacle estimation and clustering. The proposed G-eye manager system can create customized walking route for blind people using the UI manager and verify the coordinates of the path. Especially, G-eye management system designed a regional information module. The regional information module can improve the loading speed of the obstacle data by classifying the local information by clustering the coordinates of the obstacle. In this paper, we evaluate the reliability of the walking route generated from the obstacle map. We obtain the coordinate value of the path avoiding the virtual obstacle from the proposed system and analyze the error rate of the path avoiding the obstacle according to the size of the obstacle. And we analyze the correlation between obstacle size and route by classifying virtual obstacles into sizes.

The goal of this research is to develop a Remote Medical Examination System on Oriental Medicine on the very high sped information communication network. We developed a remote medical examination system based on the sample examination data of 10 patients and develop the information of search database based on contents. We analyzed the sample data and the requirements of patients, doctors, and nurses. By the analyzed result, we designed and constructed a prototype are as follow: the multimedia ORDBMS server system, network interface technology, internal/external database schema design, oriental medicine expert knowledge base design, inter-data search algorithm design and thesaurus.

Recently, as the quality of life has been improving, search items in the area of entertainment represent an increasing share of the total usage of Internet portal sites. Information retrieval in the entertainment area is mainly depending on keywords that users are inputting, and the results of information retrieval are the contents that contain those keywords. In this paper, we propose a search method that takes natural language inputs and retrieves the database pertaining to entertainment. The main components of our study are the simple Korean morphological analyzer using case particle information, predicate-oriented token generation, standardized pattern generation coherent to tokens, and automatic generation of the corresponding SQL queries. We also propose an efficient retrieval system that searches the most relevant results from the database in terms of natural language querying, especially in the restricted domain of music, and shows the effectiveness of our system.

GIS technique enhanced a space data manipulation ability and we are offering a geographic information service through various analysis. The quantity used of the water was increased in such situation according to a population increase and a city concentration phenomenon. But, to secure clear water are difficult, owing to the water shortage phenomenon, seepage and the quality of water change for worse. We decide the seepage and the system to retrieve the seepage location using GIS in order to reduce vast loss from the seepage. In this paper we proposed Leakage Sensing System using TDR technology in GIS, constructed a GIS database and pilot system to prove the validity, and simulated it using TDR in GIS.

In this paper, we described web content searching system focused on the natural monuments, the endangered and reserved wild animals, the rare wild animals relevant to CITES & IUCN red data book, and the Korean endemic species. As a result of this research, we developed system for inserting and modifying of contents and efficient web searching system on the multimedia contents.

In this paper, we address the problem of how to replace huffers in multimedia database systems with time-varying skewed data access. The access pattern in the multimedia database system to support audio-on-demand and video-on-demand services is generally skewed with a few popular objects. In addition the access pattem of the skewed objects has a time-varying property. In such situations, our analysis indicates that conventional LRU(least Recently Used) and LFU(Least Frequently Used) schemes for buffer replacement algorithm(ABRN:Adaptive Buffer Replacement using Neural suited. We propose a new buffer replacement algorithm(ABRN:Adaptive Buffer Replacement using Neural Networks)using a neural network for multimedia database systems with time-varying skewed data access. The major role of our neural network classifies multimedia objects into two classes:a hot set frequently accessed with great popularity and a cold set randomly accessed with low populsrity. For the classification, the inter-arrival time values of sample objects are employed to train the neural network.Our algorithm partitions buffers into two regions to combine the best roperties of LRU and LFU.One region, which contains the 핫셋 objects, is managed by LFU replacement and the other region , which contains the cold set objects , is managed by LRUreplacement.We performed simulation experiments in an actual environment with time-varying skewed data accsee to compare our algorithm to LRU, LFU, and LRU-k which is a variation of LRU. Simulation resuults indicate that our proposed algorthm provides better performance as compared to the other algorithms. Good performance of the neural network-based replacement scheme means that this new approach can be also suited as an alternative to the existing page replacement and prefetching algorithms in virtual memory systems.

Information management area faced new challenge arised from the developments of the computer and the information network, and the advent of information super highway. With deep perception of importance of the information, developments of information technologies, and change of the users' environment, we came to envision the digital library. This paper intends to describe the concept and function of the digital library, and to examine some of information technologies such as CD-ROM, OCR technology and image scanning, hypertext, hypermedia and multimedia. And it also considers the strategies for electronic information services and the applicability of the current information technology for digitalization by case studies of the existing database systems.
