In the simulation, humans move randomly and social distancing measures are implemented when the number of infected humans exceeds 5%. The virus is defined by two traits: the infection rate between humans and the virus attack, represented by strings and floating-point genes, respectively. The progression of the disease is calculated through the “life system” based on the competition between the virus attack and the human recovery rate. The viruses were classified into subspecies based on genetic similarity. Through analysis of the changes in traits per species, it was concluded that an increase in infection rate and a decrease in virus attack within the body were favorable variations for the survival of the virus. Simulation results were compared with the daily new confirmed COVID-19 cases in Sweden, demonstrating accuracy of the simulation. This simulation is more realistic and adaptable in terms of the implementation of mutations and immunity compared to existing spread models. It is expected that by analyzing the effectiveness of quarantine policies, the damage caused by infectious diseases could be reduced drastically.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127836573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a systematic teaching-learning process was presented through the development of a teaching plan, and a series of curriculums such as teaching-learning-evaluation were carried out by performing SSI writing in the evaluation process. The theme of the first teaching-learning lesson plan is ‘Plastic Age, How to solve it’, and the reason for the selection is to recognize the seriousness of environmental pollution caused by discarded plastic through the recognition of the problem of plastic items that are easily used and discarded, and to seek experimental and social countermeasures to solve them. The class was conducted by exploring the current status of plastic appliances, starting with plastic, and finding ways to solve problems through the study of larva eating plastic. The learning objectives were to recognize environmental and social problems caused by plastic, to find ways to reduce plastic waste, and to present scientific methods for problem solving through argumentation. The second subject of the teaching-learning lesson plan was selected as ‘Seeds, Dominate the World’, and the reason for the selection is to examine the seed patent rights of multinational corporations and analyze the problems caused by them, and ultimately to think about why biodiversity is important between the universal interests of mankind and the interests of specific companies. The class established the concepts of species diversity, biodiversity, seed banks, and life patents, identified the current status and problems of agriculture around the world due to patented seeds, and established their own claims through advocacy or refutation of seed bank establishment. The purpose of the study was to identify the current status and problems of the cotton industry in India, identify the seed industry in Korea, identify the status of GMO seeds in the United States, and identify the problems of life patents in multinational companies such as Monsanto. In SSI writing, or evaluation after teaching-learning, students were aware of given social science problems, sought ways to solve problems, and presented scientific methods for problem solving through argumentation.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128534034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the camera is pointed at the Dokdo diorama, virtual objects such as birds and ships are augmented, and the sounds of waves and seagulls are combined to create a sense of presence. Users can move their bodies to explore different parts of Dokdo, and interact with specific elements of the island, such as rocks and structures, to deepen their understanding of the island while hearing explanations of the elements they want to see. DokdoTour was developed using CoSpaces as the main development environment and MageCube for augmented reality implementation. In the future, if the DokdoTour is developed with 3D game engines such as Unity3D and Unreal by professional developers, it is expected to become a service with sufficient commercial value for education and non-face-to-face tourism. The system is also highly scalable, as it can be applied not only to Dokdo but also to various industries that can be made into dioramas. Although it was developed with CoSpaces, an educational platform, the DokdoTour is expected to be a prototype and a good reference for implementing an augmented reality system using dioramas in the future, including the process of directly generating voices for elements using artificial intelligence voice generation services and the process of implementing reality blending for realistic augmentation by scanning dioramas in three dimensions.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131094978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is not difficult for middle school students to understand the solution of the NIM game and solve the problem while obtaining the logical sum expressed in binary. However, unlike the enrichment course, R&E education for gifted students explores new mathematical properties beyond the given problem-solving method, and experiences the rediscovery of principles, reinvention of forms, and re-creation of games through various transformations (making, development). We should be able to guide them through these methods. As a result of re-creation mathematics through recreational activities, students created a modified NIM game that extended it in addition to several known modified NIM games. The results of this study can be used for the development of modified NIM games and will be helpful for teaching R&E in the secondary school course.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125839151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The labia of dragonfly nymphs can be categorized into two types based on their shapes: Scooped and Flat. Orthetrum albistylum and Anax parthenope were selected respectively as the most representative species of the scooped and flat labial types. This study aimed to examine the hunting behavior of dragonfly nymphs through analyzing the biomechanical characteristics of the scooped and flat labia and three separate analyses were performed. First, we conducted a quantitative analysis of the labium structures by measuring the length, mass, and joint angle of each part through anatomical dissection. The result showed that the scooped labium has limitations in opening its joints compared to the flat one due to structural difference. Second, we analyzed hunting videos of dragonfly nymph using the Tracker program to measure physical quantities such as velocity and acceleration. The average Striking velocity of the labium is 0.40m/s in O. albistylum and 1.53m/s for A. parthenope. Third, we conducted two additional biomechanical analyses: (1) we calculated the magnitude of the force involved in the strike and (2) we compared the water resistance that the labia encountered during hunting using a second-order differential equation that calculates terminal velocity of damped oscillation. Our findings may suggest that the differences in the biomechanical characteristics of the labia can explain the ecological differences between O. albistylum and A. parthenope. We found out that O. albistylum is better adapted to catching small prey, whereas A. parthenope is more adept at catching larger and faster prey. This study is not only expected to contribute to better understanding of insects, but is also expected to be highly valuable for future research on biomimetic devices.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131288006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teachers’ self-efficacy and their attitudes towards gifted students are important because they impact teachers’ perception and performance, which in turn could impact on the motivation and academic performance of gifted students and their chance of being identified for gifted education programs. Although many studies have emphasized the positive effects of initial teacher training on pre-service teachers’ self-efficacy and attitudes towards students, none of the universities in South Korea that offer a bachelor’s degree in primary education provides a compulsory course in gifted education, and elective course offerings are limited. In total, 481 fourth-year South Korean primary education major students participated in the survey. As a result of the survey, significant correlations were found between the pre-service teachers’self-efficacy in teaching gifted students and their supportive attitudes towards gifted students and gifted education.

Our goal is to minimize manual effort and create exam schedules that meet specific requirements. To achieve this, we utilize exhaustive search techniques to ensure that each student’s enrolled subjects are included in their exam schedule. We measure student fatigue using an objective function that takes into account their satisfaction with each subject and its placement. We continuously generate schedules with lower average and standard deviation of fatigue for each student. To further optimize the schedules, we consider additional constraints such as grouping subjects that cannot be scheduled on the same day and taking into account the number of exam rooms available. Given the large number of possibilities involved in the search, we sort subjects and exam times according to fatigue levels and prioritize the search for difficult-to-allocate subjects and exam times.
