General branches of science and engineering now enjoy being substantially repleted in their databases. However, comparing the databases of such branches with chemistry or medical science and pharmacology, the strata do not seem to be fully equipped yet. As a matter of fact, the variety of such databases in practical application is still somewhat limited. Moreover, these databases are, with a few exceptions, prepared abroad. In this paper varieties and features of databases now available on the market for each database service system, as well as crucial points for practical use are introduced. At present, it is focussed more or less on the application of bibliographical information. Yet, it would be inevitable to equip them with factual data in order to increase the efficiency of research and development activities. Of course, it is still not easy to solve problems for better profitability and higher technical achievement. The author wishes to emphasize the necessity to fully equip the commercial factual database for said branches as quickly as possible.

For the National Geo-Spatial Information System the development of the National Digital Basemap database is actively underway in Korea. For the National Digital Basemap database to be truly useful for various applications development it is essential to maintain its reliability. To maintain the reliability of the database it is necessary to understand the nature and the frequency of the errors in it. In general, a data inspection under the standardized quality control process is required to maintain the quality of a large database. In addition, it is important to maintain complete and detailed records of the inspection results so as to understand the relationship between the m and other factors causing errors. These records can be used as a reference for map updates and future application development. The goal of this study is to count the frequency of errors based on the typology of errors found in the digitized map inspection process and to analyze the correlation between errors and topographic composite quotient This study also provides guidelines for the inspection process regarding the error-prone cartographic elements in the digital map generation process.

In this paper, I discuss the development techniques and implemented type of DAVIS, a standalone JAVA-based application, by which statistics application can be downloaded from a web server, stored and installed to a client. Also I discuss both the server-based application and the client-based application that analyze statistics data. Considering the strengths and weaknesses of types discussed previously, I propose an advanced learning system of statistics that can execute an application in a client by client request. And data used in this system are loaded from a database server or input into a client by users.

Various web applications are developed as the Internet is popularized in many fields. However, in most cases of web application development, systematic analysis is omitted and developers jump into the implementation. Therefore developers have difficulties with applying the development methods for a large scale project. The approach of creating an analysis models of a web application from a business model is proposed for the rapid and efficient development. The analysis process, tasks and techniques are proposed for this approach. The use case diagram and web page list are created from business modes that is depicted using the notation of UML activity diagram. The page diagram and logical / physical database models are created using the use case diagram and the web page list. These analysis models are refined during the detailed design phase. The efficiency of proposed method has been shown using a practical case study which reflects the development project of the web application for supporting the association of auto repair shops.

GIS is essential to regional development and management in informatization age. But utilization of GIS in Korea remains still elementary area of automated mapping or facility management. In this paper, we suggest executable principles that are able to enhance and improve the efficiency of regional development affairs using GIS DB. In order to accomplish the role of planning support tool, GIS DB have to be plentiful geographic contents. Metadata DB, user-friendly application interface and compatibility of data between the public and the private must be constructed in GIS DB. And geographic information should be shared between the public and the private.

The purpose of this study is to develop a growth prediction model that can predict growth and development information influencing the production of citrus fruits: the growth model algorithm that can predict floral leaf ratio, number of fruit sets, fruit width, and overweight depending on the main period of growth and development with consideration of the applied weather factors. Every year, large scale of manpower was mobilized to investigate the production of outdoor-grown citrus fruits, but it was limited to recycling the data without an observation supporting system to systemize the database. This study intends to create a systematical database based on the basic data obtained through the observation supporting system in application of an algorithm according to the accumulated long term data and prepare a base for its continuous improvement and development. The importance of the observed data is increasingly recognized every year, and the citrus fruit observation supporting system is important for utilizing an effective policy and decision making according to various applications and analysis results through an interconnection and an integration of the investigated statistical data. The citrus fruit is a representative crop having a great ripple effect in Jeju agriculture. An early prediction of the growth and development information influencing the production of citrus fruits may be helpful for decision making in supply and demand control of agricultural products.

Ontology can be used as a formal and demonstrative knowledgebase that can express the thinking process of human. Software Development Process is a collection of ideal practices and procedural system that is performed by mature organization with high capability. Due to complexity of process, however, Software development Process often results in obstruction of introducing and improving simple process activity. While introducing and improving software development process, application of ontology to complex software development process is more approachable by showing deductive results of relationship between ISO/IEC 15504 and CMMI. In this paper, we demonstrate a methodology that utilizes the improved process database conceptually mapping between ISO/IEC 15504 and CMMI using ontology.

Flooding caused by torrential rains and landslide causes the deaths of people and property damage as well as traffic congestion and isolation. Driver enters the dangerous area when driver doesn't recognize disaster information on the road and the damage is spread over time. In this paper, we will develop a smart phone application to collect dangerous disaster area information and a system based on C/S to manage the data received from the smart phone application. This system can analyze dangerous disaster areas using the data received from the smart phone application and the spatial database analyzed dangerous disaster areas is displayed in the smart phone application using a map server. We think that the suggested system provides more efficient information to user.

The importance of factual database is becoming larger and larger as the application of computer in design and processing is increasing. To follow up and support this demand and tendency, construction of factual database is necessary. The goal of this research project is to construct a factual database about the creep properties of high temperature materials. A factual database on the creep properties of 25 kinds of high temperature materials was constructed. Domestically produced data which were appeared in journals, theses, reports, etc., were collected and used as a input data source. Evaluation on these collected data will be done during the 2nd year of this project. In addition to this database construction, an experimental facility to produce creep crack propagation data was set up.
