  • This paper is focused on the development of sea wave experimental module for the science gifted students and the potential of its application in high school earth science. Sea wave experimental module for the gifted was characteristics by five phases: Engagement, Exploration, Explanation, Elaboration, and Expansion. Subjects were 16 gifted students, who were 10th graders and have been taught in the adjacent Education Institute for the gifted of Education Districts, Daejeon Metropolitan Office of Education The changes of inquiry ability and knowledge achievement were analyzed according to analysis of experimental report and pre-test and post-test. Experimental module for the gifted was very effective on inquiry skills as follows: control of variables, experimental designing, and selecting tools of experimental process. And also it was positively effective on achievement. The result of this study suggested that experimental module for the science gifted should be very meaningfully to improve scientific ability of them, and the development and application of experimental module for the science gifted be needed for them.

  • This research was planned to analyze the students' science writing tendencies according to the level of meta-cognition for using as materials of selection of gifted students. To get results, meta-cognition writing tests which measured critical thinking ability and problem solving ability were developed, and the students' the level of meta-cognition was measured. Thereafter We analyzed the students' science writing tendencies in accordance with the level of meta-cognition through the science writing with meta-cognition task(the main theme are expectation; explanation; claim; criticism; imagination), and found out the students' ability of science writing was different with the level of meta-cognition. Students with the low level meta-cognition did not represent their thinking well, but students with the high level meta-cognition were try to upgrade their writing through highly concentration and perceiving theirs writing mistakes. As this results, science writing is useful as materials of selection of gifted students.

  • This study was to investigate the preconception and phases of children's conceptual change about season through an instruction on the concept. Participants in the study were seventy-eight fifth graders in two classrooms of an elementary school located in Incheon city. Children's preconception was examined using a questionnaire, consisted of a drawing and literal explanation. The questionnaire also was used at the midterm-test, post-test, and one-week delayed-test. The results shows several findings as follows: some children (a) change their synthetic conceptions to form another synthetic conceptions through the instruction; (b) exhibit that their conceptions are unstable; and (c) are mainly influenced by distance and heating effect on the seasonal spatial distribution between the Earth and the Sun, and by the Earth's rotation on the seasonal change of constellations in acquiring the scientific concepts.

  • Alternative medicine is defined as the practices used for the prevention and the treatment of diseases that are not taught widely in medical schools, nor generally available inside hospitals. Alternative medicine or therapy is of growing interest to the general public. We conducted a survey to determine the prevalence and patterns of using alternative medicine such as herbal medicine acupuncture, folk medicine, health food and diet, yoga, qi therapy, shiatsu, chiropractics, homeopathy etc.. Based on 794 completed questionnaires, 484 respondents(61%) reported using at least one form of alternative medicine for their medical problems. The major medical conditions for which they used alternative medicine were back pain(85.6%), arthritis(85.4%), hypertension(85.2%), cerebrovascular disorders(86.4%), and insomnia(84.6%). The types of alternative medicine frequently used were herbal medicine, acupuncture, folk medicine, and health food. The reasons why the vast majority of people sought after alternative medicine was that: less side-effect, it is not harmful, it is more effective, there is a shorter waiting time, and a better explanation fur the conditions and a kinder therapist. We found that the frequency of using alternative medicine in the health care system was high. Physicians need to be more aware that many patients may be using alternative medicine. Further survey of the nation-wide prevalence of alternative medicine, and scientific study into the efficacy of this medicine should be followed. In the meantime, we suggest paying attention to possible harmful effects caused by some sorts of alternative medicine.

  • The purpose of this study is to analyze university students' views on STS(science-technology-society) literacy. We divided definition and interaction of science, technology and society in the views' category about STS literacy. Research object was three universities' students(engineering department: 119 and social science department: 117) in Seoul and Jeju. Research result was following. First, students from engineering department valued convenience of life in the definition of science and technology. Students from social science department valued explanation of phenomenon and experiment in the definition of science and technology. Second, two groups perceived inter-relationship of science, technology and society. Third, two groups had different opinions about responsibility and ethics of scientific technician and technical use. As a result of this study, students perceived highly about STS literacy. Therefore, the result of this study will provide important implication for establishing and operating subjects about STS literacy in university curriculum.

  • In 1969, Y.J. Yun wrote the terrestrial navigation text book that discussed earth sciences, aides to navigation, chart and publications, tide and tidal current, piloting, rhumb-line sailing, great circle sailing grounded on the hand-on background and theory. It has still been used as a principle text book in a lot of maritime academies and schools. And many contents and definitions came from other terrestrial navigation books published in the United States of America, the United Kingdom, and Japan. But some of them have caused the misunderstanding because they had no enough explanation and explained by incorrect items. In this study, we have found out the problems in the terms course and heading which are related with the direction of the vessel movement, and proposed the amended definitions in order to prevent the misunderstanding and confusion. of them.

  • In philosophy of mind, both reductionism and deflationism claim that the problem of mental causation is overstated, but the reason why they claim that way is quite different. On the one hand, for deflationism, since the problem of mental causation is bogus problem we need to focus on epistemology or scientific explanation rather than metaphysics. On the other hand, although the proponents of nonreductionism seem to think of the principles of causal closure of the physical and causal exclusion proposed by Jaegwon Kim as tenable, they do not go with the reductive approach to the problem of mental causation. Instead they stay with the concept of supervenience to overcome mental causation problem that, reductionists think, leads us to the dilemma situation. Of course, deflationists do not think that supervenience is plausible not as much as supervenience physicalists think that it is. If so, in what way and how do deflationists regard the problem of mental causation as a bogus problem? In this paper, I shall examine the most plausible response to mental causation problem, the contemporary version of mind-body problem by critically discussing and clarifying matters concerning the problem.

  • 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.

  • A posteriori physicalists criticize non-physicalist arguments based on the framework of two-dimensional semantics. Most of them argue for physicalism based on the analogy between scientific identity statements and psychophysical identity statements. This paper argues for another version of aposteriori physicalism, so called physicalism employing 'phenomenal concept strategy' or 'exceptionalist strategy', which appeals to merely the nature of phenomenal concept without recourse to a semantic framework. Loar's phenomenal concept strategy employs the aspect of our recognitional ability of objects in criticizing non-physicalism, leading to the argument that phenomenal concepts are 'exceptional' in applying conceivability-possibility link. I critically examine Stoljar's, Chalmers', Raffman's criticisms against Loar's exceptionalists strategy. Loar's phenomenal concept strategy reflects well our psychological aspects surrounding the acquisition and the possession of 'phenomenal concept'. In several respects, Loar's exceptionalist version of a posteriori physicalism is the best explanation for accounting for both the explanatory gap and the a posteriority of psychophysical identity.

The Problem of Individuality and Intrinsic Norms in Canguilhem's Philosophy of Life (캉길렘의 생명철학에서 개체성과 내재적 규범의 문제)

  • George Canguilhem(1904-1995) is one of the rare French philosophers of the 20th century to develop an approach that was shaped by a medical education. For him, medicine is considered as "a technique or an art at the junction of many different sciences, rather than a proper science." The thesis that medicine is a technique is presented not at a practical level, but on an axiological horizon which reflects the totality of humanity. This character of medicine became a motive that concretized Canguilhem's philosophical thinking. Medical knowledge is not an application of physiology, but is derived from clinical observations which are based on the personal experiences of each patient. If medicine were based on scientific knowledge and its practice the very application of this pure knowledge, the patient might be a passive object. However, the patient doesn't remain passive, but reacts to the menace of disease according to attitude that the patient developed over the course of his or her life. Canguilhem characterizes this point as 'normativity', the core of individual life, which eludes positivist medicine. Here appear the essential contents of his vitalism. Although they emphasized the activity of individual living being, other modern French vitalists didn't consider this dimension of norms. Since the normativity in Canguilhem concerns the subjectivity of the first person, it avoids a mechanical form of explanation. Thus Canguilhem's originality is found in his derivation of the essence of medicine from individuality, values and norms.
