  • This study investigates methodological implications of cyberspace and information technology for online survey research Online survey method provides useful methodological tools for collecting empirical data for the study of cyberspace, In terms of sampling frame , selection method, and questionnaire from four major types of the online survey research can be found: member survey visitor survey e-mail survey and the electronic survey. Online survey research with sample design(population specification error. sampling frame error, selection error) measurement (measurement instrument bias system-related processing error, nonrespone, and response bias) and research ethics (privacy and netiquette) pose important methodological issues for the survey. The realization of the technological possibilities of online survey will be possible only through a right consideration of these issues.

  • It is the purpose of this article to present a brief and systematical behavioral methods in recent developed behavioral pharmacology. Specifically, the present review has been organized around three major topics reflecting both current research emphasis in behavioral pharmacology and methodological applications to the study of psychopharmacological actions of crude drug or herb medicine. The first major topic focuses upon the appropriate experimental design especially in the study of psychopharmacology. A large number of factors should be controlled to have a bearing on design of studies reflecting to psychological effects of drugs. The second section presents several recent methodological developments in behavioral pharmacology involving Turner's screening methods and several types of conditioning techniques. The last section calls specific attention to the observation of behavioral development processes in relation to the activity of pharmacological agents and emphasizes critical period of drug treatment.

  • This study investigated methodological principles of childhood education in the Choson Dynasty. The study was conducted through review of literature, particularly through the analysis of the textbooks used in childhood education and the Confucianism Classics. The ultimate goal of childhood education in the Choson Dynasty was the moral completion of human beings through daily practice. The methodological principles of childhood education were the principles of learning by imitation, early education, the inseparability of knowing and doing, education for Ye(禮) in daily life, sex-role education, and teaching with consideration of the developmental characteristics of the children. The scientific validity of such methods of traditional education is verified in terms of its many points corresponding to important principles of modern education.

  • In this paper, we introduce the methodological system design via feature selection using Principal Component Analysis and Particle Swarm Optimization algorithms. The overall methodological system design comes from three kinds of modules such as preprocessing module, feature extraction module, and recognition module. First, Histogram equalization enhance the quality of image by exploiting contrast effect based on the normalized function generated from histogram distribution values of 2D face image. Secondly, PCA extracts feature vectors to be used for face recognition by using eigenvalues and eigenvectors obtained from covariance matrix. Finally the feature selection for face recognition among the entire feature vectors is considered by means of the Particle Swarm Optimization. The optimized Polynomial-based Radial Basis Function Neural Networks are used to evaluate the face recognition performance. This study shows that the proposed methodological system design is effective to the analysis of preferred face recognition.

  • Objectives: The purpose of this study is to assess the methodological and reporting quality of the systematic reviews in the Journal of Korean obstetrics and gynecology. Methods: Systematic reviews in the Journal of Korean obstetrics and gynecology were selected from January 1987 to February 2021, by searching Koreanstudies Information Service System (KISS) and the search system of the Society of Korean medicine obstetrics and gynecology. The methodological and reporting quality was assessed using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2) tool and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Results: Total of 19 systematic reviews were finally included for this study. The levels of methodological quality were low in 63.2% and very low in 36.8%. As a result of evaluating the reporting quality, 22 to 15 (average 18.6) items out of 27 items (81.5 to 55.6%) were reported. Conclusions: The results of a systematic review are helpful in giving a high level of evidence. In order to improve the quality of systematic reviews published in the Journal of Korean Obstetrics and Gynecology, it is necessary to perform and report according to the the PRISMA checklist and AMSTAR 2.

  • Civil aviation cybersecurity challenges are global in nature and must be addressed using global best practices and the combined efforts of all stakeholders. This requires the development of comprehensive international strategies and detailed plans for their implementation, with appropriate resources. It is important to build such strategies on a common methodology that can be applied to civil aviation and other interrelated critical infrastructure sectors. The goal of the study was to determine the methodological basis for developing an international civil aviation cybersecurity strategy, taking into account existing experience in strategic planning at the level of international specialized organizations. The research was conducted using general scientific and theoretical research methods: observation, description, formalization, analysis, synthesis, generalization, explanation As a result of the study, it was established the specifics of the approach to formulating strategic goals in civil aviation cybersecurity programs in the documents of intergovernmental and international non-governmental organizations in the aviation sphere, generally based on a comprehensive vision of cybersecurity management. A comparative analysis of strategic priorities, objectives, and planned activities for their implementation revealed common characteristics based on a single methodological sense of cybersecurity as a symbiosis of five components: human capacity, processes, technologies, communications, and its regulatory support. It was found that additional branching and detailing of priority areas in the strategic documents of international civil aviation organizations (by the example of Cybersecurity Strategy and Cybersecurity Action Plan) does not always contribute to compliance with a unified methodological framework. It is argued that to develop an international civil aviation cybersecurity strategy, it is advisable to use the methodological basis of the Cyber Security Index.

  • This study intended to enhance understanding of concept and measurement of service quality and analyzed studies investigating dimension and attributes of service quality in both Korea and international foodservice industries. This study summarized many methodological issues related to service quality measurement, especially SERVQUAL. SERVQUAL has been criticized because performance-expectation difference operationalization threatened reliability and discriminant validity including shared method variance. Researcher suggests that future studies should understand clearly the concept of service quality and methodological issues of SERVQUAL prior to adapting SERVQUAL itself.

  • Reviewing the outcomes of studies on contemporary information science during some periods and identifying the research area exposed in its studies are essential processes to develop the research and theories of information science and to establish the academic identity of information science. This study seeks to provide the some useful methodological approaches for establishing the research area of information science. The methodological approaches to research area of information science are as follows : (1) normative approach by concepts, definitions, and principles of information science, (2) content analysis of text books, (3) content analysis of curricula of graduate courses, (4) content analysis of graduate disserations or treatises, (5) IIS(Institute of Information Scientists)'s criteria for information science, (6) professors' need assessment, (7) interdisciplinary approach, etc. These are the representative types of methodological approach and have an enough validity and effectiveness in their own way. Therefore I think of that those should be integrately applied to establishing the academic identity of information science.
