  • Recently the road traffic noise has appeared as a significant environmental issue because of dramatic increase of vehicles and expansion of newly constructed road. Therefore, this study proposes the method that improves prediction factors and models through analysis of the existing road traffic noise prediction model. Prediction factors can be improved by establishing guideline for diffraction attenuation and applying daily traffic discharge, peak traffic discharge, and average traveling speed through an analysis of level service. Prediction must be made by periods of one or five years during 20 years. Prediction models also can be improved to include better prediction model through setting the database, establishing functional relation between physical properties and noise levels by acoustic analysis, and developing models for road traffic noise prediction in residential areas.

  • To efficiently manage data varying over time and process event driven transactions, some of the various database applications recently emerged require database systems supporting both a temporal data model and active rule processing. There has been much progress in independent research on temporal databases and active databases, but studies on databases which support both functions, have been rare. In this paper, an active temporal rule model supporting both active rule processing and temporal data model is presented with its rule expression language. This active temporal rule model contributes to the active function extension of the temporal database, and to establishing the concept of data access events which refer temporal attributes of data in active rules.

  • $\ulcorner$Euibangyoochui醫方類聚$\lrcorner$ (1445) is regarded as a treasure-house of the knowledge of traditional oriental medicine which contains over 50,000 prescriptions and enormerous amount of medical information. Despite the importance and information contained in this book, it has been rarely used since it was not convenient to use this book. In this study, therefore, the establishment of database on $\ulcorner$Euibangyoochui$\lrcorner$ was carried out. Before the database establishment of $\ulcorner$Euibangyoochui$\lrcorner$ , basic works such as correction, interpretation, proofreading and translation of original text should be done. The results obtained in this study are summaried as follows : 1) During the course of studying the original text of $\ulcorner$Euibangyoochui$\lrcorner$ , the editing process and transmission of medical books in early Chosun dynasty was figured out. 2) For better correction, interpretation, proofreading and translation of $\ulcorner$Euibangyoochui$\lrcorner$ , $\ulcorner$Euibangyoochui$\lrcorner$ microfilms which are the collection of Japanese Royal Library (宮內廳 圖書寮) were obtained in this study. Through this process, the errors in the republication were able to be corrected. 3) Analyzing the organization and compilatory method of $\ulcorner$Euibangyoochui$\lrcorner$ is one of the basic requirements of understanding the scale of the whole. book and establishing database as a result. So the analysis results were used for the basic structuring of database. 4) $\ulcorner$Euibangyoochui$\lrcorner$ CD- ROM was designed in a way that the images of microfilms, original text and Korean translation can be compared by 3-D device. In addition, the convenience and proficiency of imaging the information and prescriptions of the text is one of the remarkable features of this CD-ROM.

  • Objectives Mibyeong is an ideological concept that means the state between the healthy and diseased conditions. The purpose of this study was to suggest a research direction to establish the diagnostic criteria for the Mibyeong by reviewing the research results for the Mibyeong. Methods Academic databases (OASIS for Korean database, Embase for English database, and CNKI for Chinese database) were used to search related literatures, and articles describing the concept or diagnostic criteria of the disease were selected. Results The concept of Mibyeong consisted of three different conditions: (1) subjective symptoms without a specific disease, (2) abnormal examination findings without a specific disease, and (3) a state in between health and disease. No matter which of the three conditions is applied, the spectrum of condition was very wide and diverse. Conclusions It is impossible to apply appropriate and monolithic diagnostic criteria to all types of Mibyeong. Therefore, we suggests that the Mibyeong be classified into several subtypes and the diagnostic criteria suitable for each type be established.
