As a fundamental knowledge source in a global learning environment, it is feasible to apply the relational database management systems (RDBMS), object-oriented database management systems (OODBMS), and other traditional DBMS. However, the traditional DBMSs are not feasible in semantic knowledge/ontology representation and inference. One of the reasonable ways to overcome the limitations is the semantic web-based business support framework. Especially, in this study, we focused on the development of semantic web ontology and natural language (NL)-based inference framework. To validate the efficiency of the proposed framework, we considered a reasonable scenario for course recommendation in a university.

강의별학술정보페이지는 하나의 게이트웨이에서 강의정보와 도서관자원을 통합하여 제공하는 서비스로 대학도서관의 정보서비스를 더욱 강화시킬 수 있다. 이는 여러 검색게이트를 갖는 기존의 도서관 자료 제공방식과 달리 강의별 맞춤 정보를 제공할 뿐만 아니라, 강의관리시스템과 연계하여 강의와 도서관자원을 더욱 밀접하게 연계시킬 수 있다. 국외 대학도서관의 경우 강의별학술정보페이지를 대학의 특성에 맞게 다양한 내용으로 구축하며, 대학에 개설된 전체 강의에 대한 페이지를 구축하기 위해 수작업이 아닌 자동화처리 프로그램을 도입하거나 개발하고 있다. 따라서 강의별학술정보페이지 구축 프로그램도 자체 개발혹은 상업 벤더시스템 등으로 다양하다. 하지만, 국내에서는 강의별학술정보페이지 개발이 활성화되고 있지 않으며, 시스템 개발에 대한 구축방안도 모색되지 않고 있다. 이에 본고에서는 문헌연구와 사례조사 방법을 이용해 국내 대학도서관의 적극적인 서비스 방안의 하나인 강의별학술정보페이지 구축 방안을 제안한다. 본 연구에서 제안한 강의별학술정보페이지 구축 방안을 통해 도서관의 적극적 서비스를 마련할 수 있을 것이다.

Building materials have a great impact on the health of a building's occupants. Thus, it is imperative that their health-related properties be taken into during the course of construction project. Unfortunately, no current database system exists that can provide information on the health performance of building materials at each stage of construction project management, from planning and design to building and maintenance. therefore, an inordinate amount of time and effort is required to choose the right health-friendly materials(DBHM). To solve this problem, this study aims at building a database management system for health-friendly building materials. It analyzes the health-related properties and performance of various materials, and proposes a database structure and operation algorithm. The system proposed in this study is expected to contribute to the objective evaluation of health-friendly building materials through the accumulation of relevant data.

A big database utilizes the establishing network technology, and it became an emerging trend in the computing field. Therefore, there is a necessity for an optimal and effective data distribution approach to deal with this trend. This research presents the practical perspective of designing and implementing distributed database features. The proposed system has been establishing the satisfying, reliable, scalable, and standardized use of information. Furthermore, the proposed scheme reduces the vast and recurring efforts for designing an individual system for each university, as well as it is effectively participating in solving the course equivalence problem. The empirical finding in this study shows the superiority of the distributed system performance based on the average response time and the average waiting time than the centralized system. The system throughput also overcomes the centralized system because of data distribution and replication. Therefore, the analyzed data shows that the centralized system thrashes when the workload exceeds 60%, while the distributed system becomes thrashes after 81% workload.

Systems engineering technology development program for Korea next-generation high-speed railway(KNHR) system in progress is a national large-scale system development program that is not only a large-size and complex but also multi-disciplinary in nature. Using the RDD-IOO, a systems engineering tool, the KNHR program can establish requirements traceability and development process management in the course of development. This paper presents the results from a computer-aided systems engineering application to KNHR system technology development project over the three years of activities. The traceability among the system design database in the vertical direction of SE process, as the results of the first year and the second year research was accomplished. The database in both the requirement management domain and the project management domain was developed and set up the traceability between them in the horizontal direction of the SE process in the V model as the results of the third year research. Therefore, KNHR design database was built to support the life-cycle management of the system as well as to reuse the knowledge in future programs. In the following development phase, this database will be utilized to accomplish the test and integration activities providing a baseline database. The outcome of the study contributes to the establishment of the model-based systems engineering approach as a best practice in the accumulation and advancement of systems engineering technology for railway system development.

The book, "Euibangyoochui醫方類聚"(A.D. 1445) is called the treasure-house of the knowledge of medical science, due to the 50,000 prescriptions and an enormous amount of medical information that it contains. But in spite of the importance of this book, a convenient and efficient method to use the information in this book isn't developed yet and as a result the use of this book in a low state. Therefore before than anything else, there is necessity to establish the database on "Euibangyoochui". Before the establishment of database on "Euibangyoochui", there are basic works that should be preceded as follows; like the correction through investigating and comparing between the texts that are related with "Euibangyoochui", interpretation, proofread and translation to Korean of the original. And also bibliographical research on "Euibangyoochui". The compilatory course and transmissional system of the medical books in first term of Chosun(朝鮮) was able to apprehend through the bibliographical research about "Euibangyoochui". Also, many emergency medical books and books about the prevention of the infectious diseases mostly based on "Euibangyoochui" were wrote and put to practical use. And this fact, tells us that the compilation of "Euibangyoochui" was supported by the government of Chosun as means to accumulate the medical knowledge.

As the significance of knowledge convergence continues to grow, universities are making efforts to develop methods that promote multidisciplinary learning. To address this educational challenge, our paper applies network theory and text mining techniques to analyze university curricula and introduces a graphical syllabus rendering method. Visualizing the course curriculum provides a macro and structured perspective for individuals seeking alternative educational pathways within the existing system. By visualizing the relationships among courses, students can explore different combinations of courses with comprehensive search support. To illustrate our approach, we conduct a detailed demonstration using the syllabus database of Yonsei University. Through the application of our methods, we create visual course networks that reveal the underlying structure of the university curriculum. Our results yield insights into the interconnectedness of courses across various academic majors at Yonsei University. We present both macro visualizations, covering 18 academic majors, and visualizations for a few selected majors. Our analysis using Yonsei University's database not only showcases the value of our methodology but also serves as a practical example of how our approach can facilitate multidisciplinary learning.
