  • Improving of scientific inquiring ability is the major goal of current science curriculum, and the 6th science curriculum. But science educators consider that the existing textbooks and teaching manuals are insufficient to achieve this goal. For science teachers at teaching site to guide students efficiently in research work, development of teaching-learning programs is urgently demanded. Hypothesis Verification Learning Model(HVLM) was applied to classroom situation to improve ability of scientific inquiry in experiment teaching of middle school biology. The effects of the model were analyzed to suggest some approach method to reach the goal of science education in this study. The major results of this study are as following: 1. The students and teachers responded positively on this new learning model. an students were willing to participate in biology experiment and they said that to know what was unknown to them while exchanging ideas and opinions through the discussion, It was hard for teachers to instruct at the first time and it took much time for them to arrange materials ready, but it turned to be easier as time went on. 2. In science process skills, there was no significant difference statistically by new leaning model. Only the formulating a generalization or model showed significant difference statistically between the two groups. 3. For scientific attitude, experimental group did not show significant difference statistically between the two groups, but the experimental group showed statistically more significant positiveness in all areas afterwards than before. 4. In science achievement test, there was significantly higher than the control group. It is also analyzed that they remember the experiments in courses and results they planned and performed by themselves longer than these guided by teachers.

  • Collective intelligence has been focused because it plays an important role for creating knowledge. In order to solve a problem with collective intelligence, collaborative works sharing information are required. In this study, we have investigated what informations are shared while 4 science gifted students are asked for scientific explanation to the problem which is cognitive conflict. They have shared presupposition and problem in stage of problem finding, aims and means of problem solving in stage of setting up hypotheses, and constraints for evaluation and results of evaluation in stage of hypotheses evaluation. Our research tells that group can create knowledge through sharing information and make a change of their concepts. Our foundation of these spontaneous conceptual change gives an implication for gifted education.

  • In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

  • The strengthening of Institutional Review Board (IRB) and Human Research Protection Program (HRPP) for clinical research on advanced regenerative medicine reflecting the 3 Principles of the Belmont Report (Respect, Beneficence, Justice) is very important. The research institution IRB should naturally be in charge of managing the clinical research process. And it is crucial to reinforce HRPP for the protection of research subjects in institutions conducting advanced regeneration clinical research. So, it is needed to establish a Protection System for Advanced Regenerative Medical Research Subjects composed of clinical research management communication system for advanced regenerative medicine between KAIRB (Korean Association of IRB) of research institutes and National Management Agency for Advanced Regenerative Medical Research. In advanced regenerative medicine clinical research to verify safety and efficacy of the investigational drugs to the subjects with rare and incurable diseases rather than to treat the patients, it is hoped that a management system that guarantees the scientific characteristics of research and the rights of research subjects would be well organized and operated.

  • This study was analyzing what studying factors are affecting on the development of science process skills of the 5th graders in the elementary school. For this research, 2 hundreds of elementary students were chosen and questioned on 3 factors like teacher, school environment, and learning strategy which are supposed to affect the development of science process skills. According to the result, there were differences in the categories according to the region. Especially, science process skills were significantly different in level of school category(p<.05)). Science process skills were significantly correlated with teachers and school category, and learning environment in 5th grade. Based on these results, it is expected to perform analysis about the influences that studying variables have on science achievement and attitude as well as scientific reasoning ability. Also, further study is needed about the influence that these small difference have on middle and high school students, though studying variables are not statistically significant on this research.

  • Control of plasma processing methodologies can only occur by obtaining a thorough understanding of the physical and chemical properties of plasmas. However, all plasma processes are currently used in the industry with an incomplete understanding of the coupled chemical and physical properties of the plasma involved. Thus, they are often 'non-predictive' and hence it is not possible to alter the manufacturing process without the risk of considerable product loss. Only a more comprehensive understanding of such processes will allow models of such plasmas to be constructed that in turn can be used to design the next generation of plasma reactors. Developing such models and gaining a detailed understanding of the physical and chemical mechanisms within plasma systems is intricately linked to our knowledge of the key interactions within the plasma and thus the status of the database for characterizing electron, ion and photon interactions with those atomic and molecular species within the plasma and knowledge of both the cross-sections and reaction rates for such collisions, both in the gaseous phase and on the surfaces of the plasma reactor. The compilation of databases required for understanding most plasmas remains inadequate. The spectroscopic database required for monitoring both technological and fusion plasmas and thence deriving fundamental quantities such as chemical composition, neutral, electron and ion temperatures is incomplete with several gaps in our knowledge of many molecular spectra, particularly for radicals and excited (vibrational and electronic) species. However, the compilation of fundamental atomic and molecular data required for such plasma databases is rarely a coherent, planned research program, instead it is a parasitic process. The plasma community is a rapacious user of atomic and molecular data but is increasingly faced with a deficit of data necessary to both interpret observations and build models that can be used to develop the next-generation plasma tools that will continue the scientific and technological progress of the late 20th and early 21st century. It is therefore necessary to both compile and curate the A&M data we do have and thence identify missing data needed by the plasma community (and other user communities). Such data may then be acquired using a mixture of benchmarking experiments and theoretical formalisms. However, equally important is the need for the scientific/technological community to recognize the need to support the value of such databases and the underlying fundamental A&M that populates them. This must be conveyed to funders who are currently attracted to more apparent high-profile projects.

  • Inquiry has great value in environmental education(EE). Being able to see the world environmentally through 'inquiry-based environmental education' can be an important value and goal of EE. In this study, we intended to develop an EE program of measuring activity of dissolved oxygen(DO), based on the theory of 'inquiry-based EE'. Especially, we recognized the potential that DO meter can be used in 'inquiry-based EE', and we tried to develop a model of inquiry-based EE using DO meter. As a result of this research, we present specific models of inquiry-based EE about how to perform measuring activity of DO and how to use the DO meter in laboratories and streams from the perspective of inquiry of water environment. In the process of program development, we considered organization of the inquiry process, use of concept and knowledge, scientific inquiry and insightful inquiry, integration, sustain-ability, content components of 'Environmental Studies for EE', developmental level and in-forest of students. The developed EE model is a scientific inquiry model, pursuing 'explanation' based on data collection. Through this model, we tried to make students see water environment more deeply. The developed program can be applied to various water environments, like laboratories, streams, ponds, etc. It can be more effective inquiry activity if we perform measuring activities simultaneously with PH, electrical conductivity, and turbidity meters.

  • In this paper, We propose the aesthetic exploration of horseback riding is considered to be the process of pursuing physical, mental, emotional, and social beauty. Despite the search effect of aesthetics in various aspects, the study of equestrian aesthetics in the field of physical education in Korea is very insufficient. Equestrian aesthetics is being studied in the field of special physical education and is being studied in the fields of rehabilitation and therapeutic horseback riding. Horse riding is a type of exercise. However, studies that track and observe various changes are inadequate. The purpose of this study is to explore the theory of equestrian aesthetics and to explore the possibility of approaching aesthetic theory from the top of horseback riding and to extend the area of equestrian game aesthetically. Until now, horse riding has been thought to be an aristocratic sport. Today, however, everyone can participate. Horseback riding is a sport for raising livelihoods, and it is a special sport that animals and humans enjoy in harmony. Equestrianism is a method of aesthetics from below, a philosophical method of aesthetics from the top, and a scientific method of empirical or positivistic direction. This study examines equestrian aesthetics from aesthetic point of view through the whole process of horse riding. The purpose of this study is to explore the aesthetics of horse riding through an aesthetic approach from the top, and to study the nature of aesthetics, a philosophical debate on beauty, Art can be divided into two categories: empiricism and positivism. For the sake of simplicity, the former is called the philosophical method, the latter is called the scientific method, and the latter is called the aesthetic from the bottom. Generally, in art, artistic, artistic works, perfumers, if you are grasped in the triangular shape, equestrian aesthetics can be described as triplets such as horse riding, passengers, and spectators. It was not easy to give satisfactory results in suggesting a new theory or a clear discussion due to lack of precedent research.
