The purpose of this study is to present the importance of systematic database education in elementary and secondary schools in Korea. The authors compared the curriculum for database education in elementary and secondary schools of Gyeongsangbuk-do province in Korea with that of Arcola schools in the state of Illinois, US. The database industries of both countries were also compared to suggest the significance of database education in Korea. We have shown that it is urgent to include database education in IT curriculum for elementary and secondary schools in Korea considering importance of database itself as well as the magnitude and growth rate of database industries in 21st century. Contrary to our research results, however, it is shown the IT curriculums of elementary and secondary schools in Korea is hardly adequate to provide systematic database education required in information society. Based on these results, we conclude that IT curriculums should be revised to accommodate systematic database education for elementary and secondary schools in Korea.

The study reported here is a part of the Korean Science Education Database (SEDB) project, a long-term effort to improve science education by providing educational information to science educators. The purpose of the SEDB project is to improve access to science resources available to teachers, students, parents, and others. Three educational database have been investigated and discussed in depth. The Educational Resources Information Center (ERIC) that is the largest education database in the world and the Eisenhower National Clearinghouse for Mathematics and Science Education (ENC) that is creating an easy-to-use catalog of mathematics and science curriculum materials have been investigated on the aspect of system and operation. The pilot form of the SEDB developed in this study has committed itself to reaching audiences that include practitioners and policymakers. The SEDB should be a collection of the most up-to-date and comprehensive listing of science curriculum materials in the nation, because educators need better access to the best instructional materials and programs to continually improve science education our nation's science. The researchers recommend the practical tips for developing an effective science education database.

In this paper we present database model for Intelligent Peripheral (IP) of Advanced Intelligent Network (AIN). The new model is developed through four phase. (1) An information of AIN IP is classified that would be stored in AIN IP database as specialized resources, service. schema and system information. (2) The modeling criteria are developed that would be used to model information classified. (3) Object-oriented concepts are used in modelifl8 classified information according to modeling criteria captured. (4) Methods applied to developed model are grouped, and active-based mechnisms such as trigger and constraints are developed. These selected methods and attributes are encapsulated into objects. Consequently they compose an active object-oriented AIN IP database model.

Teacher, the guide of classwork, should acquire various an new knowledge and provide them for students timely. Owing to various reasons, however, they have some difficulties in research and in prior knowledge acquisition. This study is focused on the database construction scheme of elementary education data for everyone in any school and in any place to share those data. This can be accomplished by constructing a database system of elementary education data that are scattered nationwide and by providing them through present educational network.

This paper introduces a 'Hanmal' Korean language diphone database for speech synthesis, which has been publicly available since 1999 in the MBROLA web site and never been properly published in a journal. The diphone database is compatible with the MBROLA programme of high-quality multilingual speech synthesis systems. The usefulness of the diphone database is introduced in the paper. The paper also describes the phonetic and phonological structure of the database, showing the process of creating a text corpus. A machine-readable Korean SAMPA convention for the control data input to the MBROLA application is also suggested. Diphone concatenation and prosody manipulation are performed using the MBR-PSOLA algorithm. A set of segment duration models can be applied to the diphone synthesis of Korean.

This paper researched to improve the educational achievements in Database SQL education. In practice, it is not possible to taste all the cases required at database field within the given class times. Therefore we analyzed out the key issues that students must learn for database education, and provided SQL patterns matching to the issues. To validate the effectiveness of this approach, we programmed practical requirements with those SQL patterns under a hypothetical database.

The conventional database evaluation method is carried out by the way in which the person in charge of each specialty database(DB manager) composes the evaluation sheets for corretionㆍrevision on the already-constructed database in a manual method and carries out the measurement and re-education of DB workers based upon it. As a result, that way consumes much time on career information and measurement works about DB workers, causing low time and cost efficiency and lack of systematic management of DB workers, resulting in becoming the hindrance factor of databases quality improvement. This research provides on-line, red-time results of measurements about the efficiency of DB production and DB workers by combining the static measurement with dynamic measurement by DB manager, both of which utilize the System. Therefore, the DB manager can contribute to the improvement of DB quality by determining the continuation of DB production by DB workers or carrying out the re-education of DB workers without being affected by time or spacial constraints.

Recently, database technologies have been used commonly. But, ordinary technologies aren't suitable to construct a complicated database such as a classical literature database or an archaeological relic's database. Because this kinds of data are semi-structured data that doesn't have regular structures, database schema can't be defined before databases. We have proposed DREAM model for semi-structured databases. In this model, a database consists of five elements and the model has operations similar to operation of set theory. And further we have introduced dynamic schema "shape" showing structure of each element. We have already realized a prototype of DBMS adopting DREAM model (DREAM DBMS) and constructing function of shapes. However, shape is imperfect to describe database structures because it can't explain nested structures of elements. In this paper, we will profuse a "shape graph"that is dynamic schema showing database structures more exactly and extend the DREAM DBMS. Further we will evaluate the performance of constructing function of shapes and shape graphs.

In the current field of Medical Informatics, the information increases, and changes fast, so we can access the various data types which are ranged from text to image type. A small number of technician digitizes these data to establish database, but it is needed a lot of money and time. Therefore digitization by many end-users confronting data and establishment of searching database is needed to manage increasing information effectively. New data and information are taken fast to provide the quality of care, diagnosis which is the basic work in the medicine. And also It is needed the medical database for purpose of private study and novice education, which is tool to make various data become knowledge. However, current medical database is used and developed only for the purpose of hospital work management. In this study, using text input, file import and object images are digitized to establish database by people who are worked at the medicine field but can not expertise to program. Data are hierarchically constructed and then knowledge is established using a tree type database establishment method. Consequently, we can get data fast and exactly through search, apply it to study as subject-oriented classification, apply it to diagnosis as time-depended reflection of data, and apply it to education and precaution through function of publishing questions and reusability of data.
