  • This study examined the thinking styles of scientifically gifted students on the basis of Sternberg's theory of mental self-government, and the relationship between thinking styles and self-regulated learning ability of the students and their scientific inquiry ability by the different types of thinking styles. 110 middle school students who belonging to the university science-gifted education center participated in this study. 13 thinking styles were postulated that fall along 5 dimensions which are functions, forms, levels, scopes and leanings of the mental self-government. Scientifically gifted students responded to the Thinking Style Inventory (TSI) that standardized Korean version, Self-regulated Ability Inventory and Test of Science Inquiry Skills Inventory (TSIS). The results indicated that scientifically gifted students prefer legislative, liberal, external, hierarchical and judical thinking styles, rather than conservative style. This result also showed that subscales of thinking styles were significantly correlated with self-regulated learning ability and scientific inquiry ability. The legislative style, hierarchical style, local style and liberal style were significant predictors of self-regulation learning ability. The legislative style was significant predictor, whereas oligarchic style was negative predictor of scientific inquiry ability. The results of k-means clustering analysis and MANOVA showed that the self-regulated learning ability and scientific inquiry ability were significantly correlated with the pattern and level of thinking style.

  • The Reform Movement(戊戌變法) of 1898 was a boundary tablet of modern history of science and technology which inherited the past and ushered in the future. Kang Youwei(康有爲), as a leader, his scientific thoughts opened up the way of Chinese enlightenity campaign and pushed the development of Chinese modem science and had an important position in modem history of scientific thoughts. The dissertation analyses the source, establishment and content of Kang Youwei. Kang Youwei developed the useful and discarded the useless of the view of implement science held by the Westernized Party, undertook a deep and throughout thinking on the nature of science, had cognition of scientific methods and spirit, by which he criticized negative proneness of ancient Chinese views of science. He put forwards a series of practical suggestions on political reform that provided a solid guarantee and support in system for scientific development. Kang Youwei rooted in the soil of Chinese traditional academic culture, but also western learning in modern western civilization. Kang go through Westernization Movement since the in-depth study of Western natural and inevitable outcome of the social sciences, are giving to science and technology. Although he was originally of Western "science" has a lot of misunderstandings and prejudices, but these shallow hazy perceptual knowledge, his view of science which constitutes the basis of the formation. In the course of scientific inquiry, Kang has begun to explore the essence of scientific development. He has a gut feeling that behind the scientific discovery of the existence of a force, which is the scientific truth and is used to grasp the scientific method. After contact with the Western world, with the traditional "Heaven(天)", and modern Chinese intellectuals began to "axiom(公理)" to recover his traditional "Heaven" of the new understanding is reflected mainly in "Zhutianjiang(諸天講)". "Zhutianjiang" is the Kang Yuwei in the absorption of traditional astronomy knowledge base, will the traditional arithmetic, as well as Buddhism and the West since the twentieth century, new knowledge of astronomy combines written. Kang while recognizing that scientific instruments, is nothing more than an extension of the role of the human senses and make the "Dao(道)" is more clear, but the "artifacts(器物)" caused by the inherent limitations of the limited nature of human knowledge, which is "Heaven" boundless nature of the broad terms, refused to concede defeat to. In reality, the activities of political reform, he gradually recognize this real-world helpless, and he recognized that the real world to achieve common ground of social ideal is impossible, so he chose comfort in life that people really get a stage of "Tianyou(天遊)". This is the cause that his writing "Datongshu(大同書)", at the same time, followed by writing "Zhutianjiang" talk "Tianyou".

  • Since the study of student's preconceptions and their effects on the learning of relevant subjects became an influential research area with high significance, the research area bas mainly been concerned by science educators. However, it was not until the year of 1983 that the area received recognition of various fields other than science education. The recognition was given by the Scientific American when it published a paper reporting a misconceptions in mechanics. Studies concerning misconceptions primarily interested in the following questions: What kinds of theoretical bases do preconceptions or misconceptions have? What are the sources of those conceptions? How are the misconceptions changed into or improved to scientific concepts? What are the efficient teaching methods appropriate for reducing the number of the misconceptions after instruction? Those questions are partly answered by experimental psychology and by philosophy of science, especially epistemology. Therefore, the paper will examine the theoretical background for and the sources of the misconceptions through literature review. Then, a few learning and teaching theories currently carrying great prestige in educational practice will be interpreted in terms of the knowledge of preconceptions or misconceptions.

  • Caring is being rediscovered as a central and unifying concept of the nursing. Traditionally, nursing profession has emphasized spirit and activities of caring. But there is little efforts to study the caring phenomena scientifically and systematically in nursing, and then the concept of caring is still remained unclear and ambiguous. Changes of social, and health care environment are threatening the philosophy and practice of caring, so it is urgent to identify caring more scientifically and to rediscover the nature of nursing discipline. Knowledge of the caring is essential component for the development of nursing as a science and a profession. The first thing to study a concept is thought to be the analysis of the concept. So in this study, concept analysis of caring was performed to clarify the concept of caring as a basis for the study of caring afterward. The approach used for the concept analysis of caring was the approach presented by Walker and Avant. The defining(or critical) attributes of caring identified in this study were (1) a series of activities for helping others, (2) concern and devotion. (3) interpersonal relationship, and (4) scientific and systematic process. The identified antecedents of caring were (1) awareness of other's needs for help, and (2) moral and cognitive motivation for helping others. The identified consequences of caring were (1) healing, (2) satisfaction, and (3) growth. And the consequences of caring were revealed to both of the care giver and the care receiver. The empirical referents of caring could be the behaviors of interpersonal relationship through scientific and systematic process with concern and devotion for others.

  • The important PH (paleontological heritages) with scientific, educational and esthetic values designated as natural monuments and protected by legislations of South and North Koreas are herein compared for the first time. On the basis of data (Jan. 2017) provided by the Cultural Heritage Administration of (South) Korea, a total of 457 natural monuments was designated. Of these, geological heritages are 80 in number, which includes 24 (30%) PH. Data (Dec. 2005) of North Korea show that a total of 474 natural monuments was designated. Among these, geological and geographical ones are 154 in number, which includes 22 (14%) PH. Differences between PH of South and North Koreas are regarded to be directly related with geological difference in distribution of the fossil-bearing strata between South and North Koreas. PH of Silurian corals, Devonian plants, Jurassic fishes, Cretaceous dinosaur tracks, birds (so called Korean Archaeopteryx) and pterosaurs, and Pleistocene paleoanthropological fossils appear to be scientifically significant. Together with these North Korean PH, scientific, esthetic, conservational, educational, and economical values of important PH including KCDC (Korean Cretaceous Dinosaur Coast), Jigunsan Shale, and Geumgwangdong Shale of South Korea should be evaluated as potential future candidates for international heritages.

  • A self-regulatory community fisheries management program in Korea is designed to enhance fisheries resources, to protect fishing grounds of self-regulatory communities, and to manage their fisheries resources by their own regulations and knowledge. This study explored an applicable ecosystem-based management plan based on the scientific investigation and analysis. This study suggested objectives, indicators and reference points of the ecosystem-based resource management system which are applicable to selfregulatory community fisheries. The objectives of the management system are to maintain sustainable fisheries production, to maintain optimum fishing intensity, to reduce by-catch, to conserve spawning ground and habitat, to maintain optimum habitat environment, to increase/maintain abundance of prey species, to increase/maintain stock biomass, and to conduct stock enhancement on the basis of scientific assessment. The improved methods for the assessment and management are introduced by demonstrating a self-regulatory fishery which targets on hen clam in Dong-li fishing village in Busan.

  • Exposure of nonsmokers to environmental tobacco smoke (ETS) has been claimed to be associated with an increased risk for lung cancer e. g., in the US, Europe, Japan and several Asian countries. The present paper reports on and discusses the scientific evidence available to date that can be used in order to assess this potential risk for Korea. Evidence related to three key steps in risk assessment, i.e., the characterization of a potential risk, data associating a response to a dose, and data characterizing actual exposures of people to ETS will be reviewed. The final assessment of the potential risk will be left to those qualified and commissioned with the task of risk assessment as a basis for public health policy in Korea.

  • This study introduces the development of elementary science textbooks in Korea. In Korea there has been eight revisions to the National curriculum and the development of nine textbooks. The State of Korea has organized textbook development teams, but this time the State chose the development team through public contest. Researchers suggested the 'FLOW' development model based upon results of studies in creative education and developed the new science textbooks. The 'FLOW' model includes four stages, aimed towards capturing students' interest in science (Fun Science), engaging students in various scientific inquiries and experiences (Lab. Experience), organizing their own knowledge of science (Organizing Knowledge), and to encourage students to become little scientists (Willing to be a Scientist). The textbook is a research-developmental textbook that utilizes various literature and exploration-strategic textbooks. The textbook's basis is formed upon scientists' experiences that assist in the realization of 'inquiry' that is emphasized within the science field.

  • The process of mould design in the foundry industry has been based on the intuition and experience of foundry engineers and designers. To bring the industry to a more scientific basis the design process should be integrated with scientific analysis such as heat transfer. The production by foundry techniques is influenced by the geometry configuration, which affects the solidification conditions and subsequent cooling. Numerical simulation and/or experiments make possible the selection of adequate materials, reducing cycle times and minimizing production costs. The main propose of this work is to study the heat transfer phenomena in the mould considering the phase change of the cast-part. Due to complex geometry of the mould, a block unstructured grid and a generalized curvilinear formulation engaged with the finite volume method is described and applied. Two types of boundary conditions, diffusive and Newtonian, are used and compared. The developed numerical code is tested in real case and the main results are compared with experimental data. The results showed that the solidification time is about 6 seconds for diffusive boundary conditions and 14.8 seconds for Newtonian boundary conditions. The use of the block unstructured grid in combination with a generalized curvilinear formulation works well with the finite volume method and allows the development of more efficient algorithms with better capacity to describe the part contours through a lesser number of elements.

  • The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.
