  • This paper describes and effective teaching approach to an undergraduate database course. This research draws on practical experience based on the hands-on practice approach which leads students to develop a database application utilizing various tools. Students not only learn concepts, methodologies and tools of database technology in class and through online multimedia learning aids, but also practice how to integrate them through collaborative team projects. The course employs collaborative learning approach and multimedia and internet technologies. Students are encouraged to work collaboratively on assignments and projects and to learn independently through online multimedia learning aids.

  • In this paper, SQL statements are analyzed to improve database performance in the current course registration system. The performance of the current database was measured through the execution plan of the SQL statements used in the transactions related to the course registration. Through the SQL analysis, the complemented SQL statements confirmed the improved performance. Overall, the performance of the course registration database system was improved through the analysis of the execution plan, and some improvement methods of the course registration SQL were shown as test results. The improved method is to reorganize the tables and index tables related to the course registration through database tuning, and utilize the SQL function to implement an optimized system that has evolved into a course database system with improved performance. The enrollment system re-adjusted by the proposed method showed excellent results in terms of performance compared to the previous enrollment system, and the integrated performance test result reduced the response time by 1.8 to 18 times.

  • Flipped learning is a pedagogic model in which the typical lecture and homework elements of a course are reversed. Short video lectures or e-learning contents or other learning materials are viewed by students at home before the in-class session, while students are mainly carried out diverse active learning activities such as the discussions, exercises, team projects and so on in class time. Recently flipped learning has been emerging as an effective teaching-learning method that can train the 21st century talents who can create creative values based on fusion competencies. Based on the experience in applying the flipped learning to the database class that is an elective course of the school of computer engineering through three semesters, this paper proposes a flipped learning model consists of 7 steps in detail. Also, this paper analyzes the effects and weak points of the flipped learning and proposes several things for the successful flipped learning application.

  • In the database design course, the team project is a very important process to develop students' database design competencies. In order to carry out team projects smoothly, active interaction between students and the professor as well as collaboration among team members are very important. However, a full uncontacted class was suddenly decides in the first semester of 2020, it was questionable whether it would be possible to effectively manage this course, where team projects to construct database take up a big portion. However team projects were able to proceed without major problems through interaction using real-time video media such as zoom, and discussions, quizzes, and Q&A supported by the online education support system (LMS), and online presentations, mutual evaluations, and so on. This paper shares the experience of managing engineering team projects in uncontacted classes and based on three surveys introduces desirable improving directions of this instruction and some suggestions to improve uncontacted classes overall.

  • Recently with developments of an internet and web techniques, the amount of data that are stored in database is increasing rapidly. So the range of adaption in database has been expanded and a research of Data Mining techniques finding useful skills from the huge database has been progressed. Many original algorithms have been developed by cutting down the item set and the size of database isn't required in the entire course of creating frequent item sets. Although those skills could save time in some course, it requires too much time for adapting those techniques in other courses. In this paper, an algorithm is proposed. In an Transaction Database that the length of it's transactions are short or the number of items are relatively small, this algorithm scans a database once by using a Hashing Technique and at the same time, stores all parts of the set, can be appeared at each transaction, in an Hash-table. So without an influence of n minimum percentage of support, it can discover a set of frequent items in more shorter time than the time what is used by an original algorithm.

  • Much attention has been paid recently to environmental destruction by golf course constructions in Koera. An efficiency and up-to-date technology on the planning and design practices has been requested to minimize the environmental impacts. Computerized systems for golf course design in the point of physical conservation of environment were discussed here. Geograpic Information System were applied on the process of geograpical data input and analysis through the final outputs, Simulation works by the total database management make enable to pre-investigate of the design in view of an assessment of environment impacts. It is also possible to evaluate plans easily and propose the alternatives properly. Precise quantity caculation of en-gineering works by computer system should be guarantee scientific, economic, and environme-ntally sound golf course design.

  • This paper is a study on implementation of the golf play advice system which provides advice to golfers through mobile devices. The system consists of a mobile unit consisting of a GPS receiver, a data transmitter and receiver, and a display unit, and a server unit composed of a database and advice generator. The advice generator that provides advices to the users, generates advices with IF-THEN rule-based reasoning method. The reasoning module utilizes golfer's personal records and various information in the database of the server unit. This system provides the advice to the users who play on the golf course through mobile devices, so that it is possible to provide various information similar to the screen golf using the computer simulating technology in the outdoor golf course.
