  • Scientific and technical development, as well as the emergence of new types of contracts, which do not have their expression in current legislation, force us to explore the issues of contract law to adapt to change. In this context, the principle of freedom of contract is fundamental, which states that each person has the right to enter into a contractual relationship at his discretion. However, such freedom is not absolute, because the freedom of one person should not violate the freedom of another. Together with the conflict of private and public interests, these phenomena are a field for the study of topical issues of theory and application of the principle of freedom of contract in practice. Research methods are philosophical, general scientific, and special scientific methods, in particular, system-structural, formal-legal, hermeneutic; methods of analysis, synthesis, etc. As a result of the research, the main characteristics of the principle of freedom of contract, its role for private law regulation of contract law are given; approaches to understanding the restriction of contract freedom are analyzed; typical examples and means of such restrictions are identified; demonstrated how contract freedom is embodied in the use of IT tools, which types of contracts are most common in the digital environment.

  • This study aims to compare self- and peer-assessments of science-gifted elementary students' scientific creativity. A science-gifted program on the Pascal's principle was implemented to 40 fifth-graders in the Science-Gifted Education Center for two weeks. After that, students presented their results from a scientific creativity task using the principle in class. The task was to devise a new and useful tool using the principle, and it included the students' self-assessment about their idea. During presentation, students were asked to assess the works of peers and write down the reasons that they gave the scores they gave. Shortly, student self- and peer-assessments about students' scientific creativity outcomes were compared. Based on two essential components of creativity, ideas that satisfy both originality and usefulness can be counted as scientifically creative. The main results of this study are as follows: First, the average scores of student self- and peer-assessments were 71.5 and 61.9. Second, the standard deviations of student self- and peer-assessments were 14.47 and 5.79. Third, among scientific creativity, originality, usefulness scores, only originality had a significant correlation between student self- and peer-assessment (r=.42). Fourth, the students were categorized into four groups according to the levels of their scores by student self- and peer-assessment. And the frequencies of peer-assessment group had a significant difference at p<0.05 level, according to self-assessment group (Chi Square=4.0000, df=1, p=0.0455). Fifth, through a case study by group, the results suggesting that self-assessment could be affected by the students' self-efficacy and perfectionism and such effect could also influence peer-assessment have been found. The result showed that how the student self- and peer-assessment of scientific creativity are different and what the students' thoughts on the evaluation of scientific creativity are. The findings suggested that there are several things to consider for the educators to make efforts to construct consistent assessment methods for scientific creativity.

  • The purpose of this paper is to survey the definition and scope of English Education as an academic discipline or science, relating to English linguistics, linguistics and applied linguistics. English Education has come to be regarded as fulfilling its true function when it is based on the solid scientific principles and methods of such related sciences as linguistics, English linguistics, psycholinguistics, sociolinguistics, sociology, psychology and pedagogy. English Education is, therefore, an independent and specialized applied science, interrelated with the sciences mentioned above. Thus, English Education is defined as an academic discipline which is concerned with the concrete teaching and learning of English, and which is based on the scientific methods, applications and evaluations of English. As a science, English Education has three elements: content, process and methods. Content, which concerns input, consists of the fundamental interrelated sciences and English language skills. Process refers to research methodology and analysis. Methods are the application of the theories and the processes.

  • An important and somewhat under-emphasized issue in assessing the risk potentially associated with exposure to ETS is the reliability and objectivity of the methods used to measure the actual level of exposure. Objectivity of the science is crucial in this context since this topic tends to elicit strong social, emotional and political responses among the general public and the scientific community alike. This mini-review compares the strengths and limitations of various methods used in determining ETS exposure in scientific investigations. Methods reviewed include: questionnaire, area monitoring, bio-monitoring, and personal monitoring. In particular, results of several recent studies (conducted in the United States, Europe, and the Far East) using personal monitors in combination with questionnaire and bio-monitoring, which contribute to a more reliable, objective and realistic estimates of a person's actual exposure to 575, are discussed.

  • Many kinds of teaching methods have been used to instruct ethical issues that arise in the field of science and technology. However, few teaching methods of bioethics have been validated by ethical theories, or justified based on practical utility in bioethics teaching. The aim of this article is to suggest teaching methods of bioethics that are appropriate for ethical theories and socio-scientific issues related to biological sciences in secondary schools. In the article, the teaching methods are classified into three types of ethical theories and into three types of socio-scientific issues in biological sciences. The characteristics of nine teaching/learning methods are then described in terms of appropriate bioethical issues or contexts, and ethical theories or principles.

  • Despite extensive research, performance enhancement of keyphrase (KP) extraction remains a challenging problem in modern informatics. Recently, deep learning-based supervised approaches have exhibited state-of-the-art accuracies with respect to this problem, and several of the previously proposed methods utilize Bidirectional Encoder Representations from Transformers (BERT)-based language models. However, few studies have investigated the effective application of BERT-based fine-tuning techniques to the problem of KP extraction. In this paper, we consider the aforementioned problem in the context of scientific articles by investigating the fine-tuning characteristics of two distinct BERT models - BERT (i.e., base BERT model by Google) and SciBERT (i.e., a BERT model trained on scientific text). Three different datasets (WWW, KDD, and Inspec) comprising data obtained from the computer science domain are used to compare the results obtained by fine-tuning BERT and SciBERT in terms of KP extraction.
