  • This study proposes an effective direction for operating the "Korea Baseball of Fame" based on baseball records. To clarify problems, a literature review on the case analysis of the "Hall of Fame" of the United States and Japan, an assortment and management of Korean baseball records, and a consultation with officials who work in the baseball industry were progressed. In conclusion, this study suggested building an archive database to operate the "Korea Baseball Hall of Fame" effectively. First, archives will be collected, and then managed and utilized at the "Korea Baseball Hall of Fame." Second, to preserve the memories of baseball heroes, an oral archive will be constructed. Third, baseball records will be assorted and stored in a database.

  • In this paper, we propose a new batter evaluation model that reflects the skill of the opponent pitcher in Korean professional baseball. The model consists of evaluation factors such as Run Value, Contribution Score and Ball Consumption considering the pitcher grade. These evaluation factors are calculated as different data. In order to include the evaluation factors having different characteristics into one model, each evaluation factor is weighted and added. The genetic algorithms were used to calculate the weights, and the data were based on the 2016 records of Korea Professional Baseball and the salary data of the players of 2017. As a result of calculation of the weight, the weight of the Run Value was high and the weight of the Contribution Score was very low. This means that when calculating the annual salary, it reflects much of the expected score according to the batting result of the batter. On the other hand, the contribution score indicating the degree to which the batting result contributed to the victory of the team according to the state of the economy is not reflected in the salary or point system.

  • This paper makes an attempt to find a systematic portion of the database design process, especially using the Entity-Relationship(E-R) model. Basically, we consider three aspects as a systematic portion of the database design process. They are, the strategy that a designer selects to design an E-R diagram, designer's cognitive style, and the knowledge and preference of the database designer. An experiment has been carried out in order to verify the systematic relationship between above-mentioned three aspects and the E-R modeling performance. The target system is a professional baseball system. A normative E-R diagram was constructed based upon 48 E-R diagrams produced during the experiment. The ANOVA process has been used to analyze the results. It has been found that there exist significant differences in query-answering capacity and the completeness of the E-R model among design methods. Individual differences in cognitive styles has not been found to be significantly related to the modeling performance.

  • Recently, as the form of media has been various and computer graphic technology has developed, it has been possible and attempted to present database information 3-dimensionally and dynamically. However, there was not many studies done regarding how to present 3-dimensional and dynamic information. Therefore, this study was conducted to develop presentation techniques and languages of 3-dimensional and dynamic information. This paper consists of four section. First, it was introduced by secondary research that fundamental knowledge and functions for presenting the information by the computer graphics. In other words, it was stated what is possible to present 3-dimensional information on the 2-dimensional screen and which functins becomes better as computer graphic technology has developed. Second, computer graphic model that present database information should also have hierarchical structure that database information has. Thus, it was discussed how to present information regarding how to make a structure of graphic model that present database information. There are two ways to present information- by changing structure of information and by changing graphical presentation techniques. Third, all the graphical presentation language was collected and explained. Finally, the case study of presenting statistical data for baseball players demonstrated concrete example of using graphical presentation language.

  • VSField-associated term is a single or compound word whose terms occur in any document, and which makes it possible to recognize a field of text by using common knowledge of human. For example, human recognizes the field of document such as or , a field name of text, when she encounters a word 'Pitcher' or 'election', respectively We Proposes an efficient construction method of field-associated terms (FTs) for specializing field to decide a field of text. We could fix document classification scheme from well-classified document database or corpus. Considering focus field we discuss levels and stability ranks of field-associated terms. To construct a balanced FT collection, we construct a single FTs. From the collections we could automatically construct FT's levels, and stability ranks. We propose a new extraction algorithms of FT's for document classification by using FT's concentration rate, its occurrence frequencies.
