The purpose of this study is to gain an understanding of scientifically gifted students' views on the nature of science. A multiple-choice format questionnaire was administered to 237 Korean 10th, 11th and 12th graders at the Korea Science Academy. The differences and similarities by gender and experience of R&E program on the students' views of the nature of science were investigated. The questionnaire developed by Lim(2004) was implemented for this investigation. We found that the majority of scientifically gifted students had highly possessed the tentativeness of scientific knowledge. The students who experienced R&E program have relatively high apprehension of scientists' motivation for researches and activities in social context compared to the students who did not experience an R&E program. Scientifically gifted students had relatively high apprehension that government should not control researches of scientists and relatively low apprehension of social responsibilities of scientists comparing to general high school students. The experience on R&E program was identified as a factor to effect changes in the students' views on the nature of science. The study has implications for the development of gifted program and curriculum such as running and assessing R&E program, and also the pre-service preparation of science teacher, teacher education reformat in both the practical and the policy levels.

Understanding of the nature of science (NOS) has been a consistent topic as one of the most important goals in science education for the past several decades. Even though there is a variety of research related with the NOS conducted in science education, few researches has been conducted for the conception of scientists regards to the nature of science (Bayir et al., 2014; Taylor et al., 2008; Wong & Hudson, 2008). Recently, researchers in science education turned their attention to identifying views of scientists about the nature of science since they recognized the importance of participation of scientists in science education (Southerland et al., 2003; Taylor et al., 2008). This study was conducted to examine the Korean scientists' views of the nature of science. Through the use of semi-structured questionnaire and in-depth interview the views of 35 scientists who belong to the Korean-American Scientists and Engineers Association (KSEA) regards to the nature of science were explored. Findings show that while the scientists have more informed views with respect to the tentativeness of scientific knowledge, cultural and social influence embedded in science, the limitation of science, and the collaboration of science with others, the scientists have more na${\ddot{i}}$ve views about the distinction between laws and theories, the existence of a universal scientific method, and the importance of imagination and creativity. As such, it can be assumed that the scientists cannot conceptualize their notion in a philosophical sense even though they are engaged in scientific work in reality (Bayir et al., 2014).

In this study, find out of recognition of the effect of science, society and ethical aspects on natural disasters and understanding degree of knowledge applying for SSI class aimed at elementary pre-service teachers by developing SSI training program of the 'Earth and Space' field. Also, after SSI class application we examined the change perceptions of elementary pre-service teachers. SSI training program was that elementary pre-service teachers participated in the SSI class of a variety of subjects in the field of 'Earth and Space' and directly joined in the decision-making process and reflectional discussion with colleagues as conducted in this class reflective discussion with the pre-primary teachers pre-service teachers. Elementary pre-service teachers were understanding of the nature of the science and to understand in more depth about the SSI class characteristics. This study, second grade 115 people who was taking 'science and teaching materials' course in B National University of Education at B city participated. In order to apply for SSI class, one semester based on 15 weeks until seven weeks were science and teaching materials and based on the nature of science, after 8 weeks we set the theme of the contents related to the Earth and space and give lesson applied for SSI. During 8 weeks, test subjects 4 classes were taking 50 minutes a week 100 minutes. First time has theoretical lessons in topics related to the 'Earth and space' and on the second week, each classes participate in the decision-making processes respectivly by dicussing and debating on the first week's topic as regarding social and moral aspects of it. We obtained the following results. First, elementary pre-service teachers were acquiring the results of 67% in the knowledge aspects of the 'Earth and space'. This result was determined that most of the elementary pre-service teachers were liberal arts in high school. Second, while participating in the SSI class, elementary pre-service teachers were concretely aware of the nature of SSI and the characteristics of the class. Third, the elementary pre-service teacher are thaught that introduction education courses about 'Earth and space' are needed but most of the students responded that this would require a lot of effort of teachers. This was derived from not familiar class form that did not fulfill in the science teaching methods until now.

Purpose: Contemporary consumers are increasingly adopting public displays of their loyalty towards brands: consumer dedication surpasses loyalty in that they find various ways to show their devotion to their favorite brands. The purpose of the current study is to utilize sports psychology to improve customer experience in the sports shops. Research design, data and methodology: To investigate the purpose of the study and suggest the solutions, Epistemology methods were used to analyze the nature of knowledge and various forms of attaining knowledge. As such, epistemology asks questions such as "what are constitutes of valid knowledge?". Results: This study figured out five theoretical results to suggest for practitioners in the sports retail shop based on prior research. According to the research, sports psychology can affect consumer buying behavior which builds upon specific demographics and their differentiating behavior. The results also show that males shop with specificity, while female consumers are likely to shop for pleasure. Men are also less frequent shoppers than women. Conclusions: Above all, this study concludes that a consumer decision-making study is vital in the sports retail business, and information about consumer decision-making can be an influential factor for sports retailers to increase their competitive advantage.

To have more insight into the nature of plant, plant scientists carry out phytosociological studies on such plant species. The phytosociological studies on Tridax procumbens. Linn was carried out at Imo State University, Owerri, Imo State between the months of July and September, 2018. Tridax procumbens Linn grows abundantly in the areas under tropical climate and supported by a sandy-loam soil. Morphological features showed a range of variations. Phytosociological investigation showed a Tridax- Mitracarpus-Digitaria plant community. Tridax procumbens was positively associated with Digitaria horizontalis, Mitracarpus scarber and Vernonia cinera. The Inter-relationship of T. Procumbens was thus determined. This study therefore is a contribution to the general ecology of the plant. Phytosociological studies helps plant scientist to have more knowledge into the nature of plant species. This study is a contribution to the general ecology of the plant Tridax procumbens. The study also shows that it has close association with mitracarpus Scarber and Digitaria horizontalis. More work should be carried out to find out if these plant species flower and produce seeds at the same time or not.

Importance: Rabies is a neglected tropical viral disease most often transmitted through the bite of an infected animal. Objective: This study assessed the level of knowledge, attitudes, and practices of the Shone Ttown community toward rabies. Methods: A survey-based cross-sectional study was conducted in Shone town, Ethiopia, from November 2022 to April 2023. Woreda was selected purposefully, while Kebeles and the study populations were selected by simple random sampling. Four hundred and sixteen respondents were interviewed using a semi-structured questionnaire. Results: All respondents had heard about rabies from different sources, with the majority hearing from informal sources (62%). Approximately 51.9%, 0.7%, and 47.4% of individuals were aware of saliva contact, rabid animal bites, and both as means of transmission, respectively. The survey showed that 64.4% of participants knew the 100% fatal nature of rabies once the clinical signs developed, and 35.6% did not. Approximately 51.4% of respondents agreed that killing stray dogs was an effective method for rabies prevention. In this study, 72.6% of the respondents had contact with pets, and 36.8% of the interviewees had vaccinated their dogs. Only the educational level (p = 0.03) was associated with knowledge of the transmission route. Age (p = 0.04) and educational level (p = 0.01) had a statistically significant association with knowledge of the risk of not vaccinating dogs. Conclusions and Relevance: A lack of formal education in the communities, low levels of education, and the majority of respondents acquiring their knowledge from unofficial sources are important contributors to the low levels of awareness.

This Paper analyses characteristics of the numerical controller industry in market formation and the flow of information between users and producers and the characteristic of knowledge base of the industry and discusses the difficulties derived, from the characteristics, in accumulation of technological capability In market formation between users and producers, the multi-layered market is not favorable to domestic producers in that lower end market is not large enough to provide cradle market to them which produce inferior quality and lower price than imported products. The credibility of the performance of a product is difficult to prove until a critical mass of products are sold. Therefore gaining market share is deterred by unproven credibility of the performance of the product. The flow of information between users and producers is limited. The flow of information on users environment through mass market to producers is essential for improving credibility of a product. The nature of knowledge base is tacit and the means of knowledge transmission is limited. Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. It is conjectured that these characteristics are derived from the fact that the numerical controller is the result of IT based technological convergence in controlling machining process. This paper argues that these characteristics of the industry challenges existing approach to R&D management and framework of science and technology Policy.

Learning progressions (LP), which describe how students may develop more sophisticated understanding over a defined period of time, can inform the design of instructional materials and assessment by providing a coherent, systematic measure of what can be regarded as "level appropriate." We developed LPs for the nature of matter for grades K-16. In order to empirically test Korean students, we revised one of the constructs and associated assessment items based on Korean National Science Standards. The assessment was administered to 124 Korean secondary students to measure their knowledge and submicroscopic representations, and to assign them to a level of learning progression for the particle nature of matter. We characterized the level of students' understanding and models of the particle nature of matter, and described how students interpret various representations of atoms and molecules to explain scientific phenomena. The results revealed that students have difficulties in understanding the relationship between the macroscopic and molecular levels of phenomena, even in high school science. Their difficulties may be attributed to a limited understanding of scientific modeling, a lack of understanding of the models used to represent the particle nature of matter, or limited understanding of the structure of matter. This work will inform assessment and curriculum materials development related to the fundamental relationship between macroscopic, observed phenomena and the behavior of atoms and molecules, and can be used to create individualized learning environments. In addition, the results contribute to scientific research literature on learning progressions on the nature of matter.

Educational Discourses on the nature of science(NOS) identify understanding of the role of scientific knowledge, especially the distinction between law and theory, as a crucial goal of instruction. However, the scientist community uses the terms such as law, theory, and principle without explicit definition so that the terms have no coherent meanings in their conventional language expression. The inconsistency between the norm and the reality could impose confusion on the teaching and learning. From the awareness of the problem, this study critically reviews the science education research papers and literatures on the philosophy of science which focus on the meaning of law, theory, or principle and the structure of scientific knowledge. From the examination of the science education researches, it is revealed that the disparity between the normative meanings of the law and theory by NOS researchers and actual usage of the terms is quite serious. From the review of the literatures of the philosophy of science, the necessity of the distintion of three categories: law, theory, and principle beyond the dichotomy between law and theory is brought up. By synthesizing the related literatures, we provide an outline of the characteristics of knowledges belonging to law, theory, and principle. Considering the conflict between the normative definition and the conventional language, it could be unnecessary to emphasize clear distinction on the terms as an instructional goal. Instead, the goal of instruction should focus on that there are three types of scientific knowledges of different functions and characteristics.
