In this research, we employed various data mining techniques to build predictive models for win-loss prediction in Korean professional baseball games. The historical data containing information about players and teams was obtained from the official materials that are provided by the KBO website. Using the collected raw data, we additionally prepared two more types of dataset, which are in ratio and binary format respectively. Dividing away-team's records by the records of the corresponding home-team generated the ratio dataset, while the binary dataset was obtained by comparing the record values. We applied seven classification techniques to three (raw, ratio, and binary) datasets. The employed data mining techniques are decision tree, random forest, logistic regression, neural network, support vector machine, linear discriminant analysis, and quadratic discriminant analysis. Among 21(= 3 datasets${\times}$7 techniques) prediction scenarios, the most accurate model was obtained from the random forest technique based on the binary dataset, which prediction accuracy was 84.14%. It was also observed that using the ratio and the binary dataset helped to build better prediction models than using the raw data. From the capability of variable selection in decision tree, random forest, and stepwise logistic regression, we found that annual salary, earned run, strikeout, pitcher's winning percentage, and four balls are important winning factors of a game. This research is distinct from existing studies in that we used three different types of data and various data mining techniques for win-loss prediction in Korean professional baseball games.

This study is to describe the principles and outcome of the development for a classification scheme of presidential records to manage efficiently and provide them as archival information service productively. First, this scheme accommodates a management aspect, taking consideration into the aspect of archival records as the results of government administrative duties. Additionally, governance aspects are embraced into this scheme since presidential records can be seen as the results of governing purpose. We are considering the functional aspects of the public records too. As a result, this scheme adopts both management and governance aspect. Focusing on reflecting both functional and governance aspects, first analyzes existing classification systems in domestic and abroad. Finally, this study proposes 24 first-level, 114 second-level, and 179 third-level classification categories. Archivists and classification experts examined the classification scheme for verification by advisory meetings.

The need for changes in archival studies curriculum has been steadily raised because of the wide variation of the curriculum in each graduate school. In this study, the foreign archival studies guidelines and certification standards were compared and analyzed to derive key categories and elements for developing the Korean guidelines for a graduate program in archival studies. The five key categories and elements of the guideline include introduction, mission and goal, knowledge categories, administrative factors, and conclusion. On the other hand, the 10 knowledge categories to be learned by archivists include ① The Nature of Records and Archives, ② Selection, Appraisal, and Acquisition, ③ Arrangement and Description, ④ Preservation, ⑤ Reference and Access, ⑥ Outreach, Instruction, and Advocacy, ⑦ Management and Administration, ⑧ Social and Cultural Systems, ⑨ Legal and Financial Systems, and ⑩ Information Technology. In the future, knowledge categories need to be actively reflected by the opinions of the academic community and archivists to improve the graduate curriculum.

World practice is evidence of that computer systems of an intellectual support of medical activities bound up with examination of patients, their diagnosis, therapy and so on are the most effective means for attainment of a high level of physician\`s qualification. Such systems must contain large knowledge bases consistent with the modern level of science and practice. To from large knowledge bases for such systems it is necessary to have a medical ontology model reflecting contemporary notions of medicine. This paper presents a description of an observation ontology, knowledge base for the physician of general tipe, architecture, functions and implementation of problem independent shell of the system for intellectual supporting patient examination and mathematical model of the dialog. The system can be used by the following specialist: therapeutist, surgeon, gynecologist, urologist, otolaryngologist, ophthalmologist, endocrinologist, neuropathologist and immunologist. The system supports a high level of examination of patients, delivers doctors from routine work upon filling in case records and also automatically forms a computer archives of case records. The archives can be used for any statistical data processing, for producing accounts and also for debugging of knowledge bases of expert systems. Besides that, the system can be used for rise of medical education level of students, doctors in internship, staff physicians and postgraduate students.

This study aims to suggest measures for handling copyright information on government publications during records and archives management to use them freely as public works according to Article 24-2 of the Copyright Act in Korea. Through email interviews with 17 records managers, persons in charge of government publication management, and government staff with experience in production from April 4 to June 13, 2022, this study determined the current situations and problems related to producing and managing copyright information on government publications. Based on the interview findings, this research suggested the following. First, Article 24-2 of the Copyright Act must be revised to apply the Korea Open Government License (KOGL) type 1 mandatorily to all public works. Second, a cooperative system for managing copyright information on government publications should be established to improve their production and management effectiveness. Third, copyright information, such as authors, copyright holders, copyright duration, information on the copyright property transfer, public works status, and reasons for nonpublic works, must be managed through records and archives management systems. Fourth and last, information on public works must be provided during the registration number application for government publication so that everyone can access the full texts of the publications on the National Archives of Korea website.

Presidential records which have produced during a presidency as a national center are the evidence of the presidency and main historical records. We have the responsibility to establish fundamental systems to produce such main historical records and to manage such main historical records which could help people and history to judge the presidency based upon the evidence of their activities. The historical appraisal could be achieved not by memory but by evidence. A draft of a proposed law on the management of presidential records which includes the establishment of presidential libraries for the presidential records Mecca is being moored at the National Assembly now. The presidential library is to be considered as a multi-functional national institution which is carrying out the role as an Archives, Museums and Center for the education. In addition, it is imperative for a presidential library to provide user-oriented services to enrich the usability and the value of records, recognizing the change of administration paradigm from a supplier-oriented system to a customer-oriented system. This dissertation, in order to develop presidential library service programs focusing on customers rather than the convenience of administration, reviewed programs of the U.S. presidential libraries as a developed case and proposes guidelines and applicable samples for the development of the Korean presidential library service programs.
