The purpose of this study is to investigate how Integrated Science, a new subject introduced under the 2015 revised curriculum, was implemented in 2018 when it was first enacted at the school level. Through a survey of 258 high school science teachers, we explored how Integrated Science was organized and implemented at the school level, how teaching & learning and assessment were conducted in Integrated Science courses, how teachers' learning communities were operated, what kinds of support are required for the settlement of Integrated Science, etc. Major results are as follows: A similar ratio is found between schools with eight units and schools with six units of integrated science, and in about 2/3 of surveyed schools, multiple teachers are in charge of Integrated Science lessons per classroom. In addition, lecture-type teaching methods are still dominant in the majority of the classes, and science teachers have difficulties with lack of understanding of non-major areas or burden of designing integrated teaching depending on their teaching experiences, and so on. Discussed and suggested in the conclusion are ways to raise awareness of curriculum integration, ways to support for activation of teacher learning communities, ways to support the settlement of Integrated Science, and reexamining the system of science teacher certification.

Recently, as the semiconductor integration technology due to miniaturization and high density of electronic equipment have developed, it is importantly recognized the application of thermal control system in order to release inner heat generated from chips, modules, In this study, we considered the heat transfer and pressure drop characteristics in a horizontal channel with four blocks using k-${\omega}$ SST turbulence model During CFD (Computational Fluid Dynamics) analysis, the parameters applied block width, block height, heat source and turbulence generator placement etc. As the boundary conditions of analysis, the channel inlet temperature and flow velocity were respectively 300 K and 3.84 m/s, the heat flux was $358W/m^2$. As a result, the heat transfer performance was decreased as the block width ratio (w/h) was increased, while it was increased as the block height ratio (h/w) was increased. In addition, as the arrangement of heat source size was increased to high heat flux from low heat flux, it was influenced by heat source size and the heat transfer coefficient showed a tendency to increase, When the turbulence generator was installed in the upper part of block No. 1 position the closely to the channel entrance, the heat transfer characteristics was greatly influenced on the whole of four heating blocks. and in oder to consider the pressure drop characteristics, we are able to select the most appropriate turbulence generator's position.

This study investigated a total of 529 integrated science teachers' implementation and changes to apply the curriculum-instruction-assessment. Data was collected through online survey on scientific competencies and skills, teaching-learning and assessment methods, changes of teacher's preparation, topics/materials, teaching-learning, and assessment to apply the curriculum-instruction-assessment as teaching integrated science. The results of the study were as follows: first, in the integrated science class, teachers implemented more on scientific communication and scientific inquiry among scientific core competencies, and analysis and interpretation of data collection and communication among scientific skills. Teachers often taught in lectures and used multiple choice items and short essay for evaluation. Teacher groups with less than 10 years of teaching experience appeared to be less active in teaching scientific core competencies and skills than those with more than 10 years. Second, Teachers have increased more time and efforts to search and to organize various materials in addition to textbooks, and try to integrated concepts in various fields to prepare learning topics and textbooks. Third, even though teachers made little change in implementing the process-oriented assessment, they used instructional strategies to increase student engagement in the integrated science class, restructured the instruction to provide immediate feedback after conducting the assessment. It is necessary to build a system that ensures fairness and credibility of evaluation while respecting the autonomy and professionalism of teachers.

In the midst of the aging of underground facilities in urban areas and anxiety about road excavation safety accidents, the Ministry of Land, Infrastructure and Transport began to build Underground Geospatial Infomation Map from 2015 as part of the 「ground subsidence prevention measures」 and efficient use of underground spaces. So, the scope is spreading every year. The current Underground Geospatial Infomation Map information is web-based and is operated in a desktop environment, so it is true that there are some limitations in its use in a field environment such as an excavation construction site. The Underground Geospatial Infomation Map, built and operated in a web-based environment, is a large-scale 3D data. Therefore, in order to service by transmitting data to the field without delay, it is necessary to lighten the Underground Geospatial Infomation Map data. In addition, the current Underground Geospatial Infomation Map is not unified in data formats such as 3DS and COLLADA, and the coordinate system method is also different in relative coordinates and absolute coordinates. In this study, by analyzing domestic and overseas prior research and technical use cases, a mobile Underground Geospatial Infomation Map data format and a lightweight method were presented, and a technology development was conducted to create a mobile underground space integration map in the presented format. In addition, the weight reduction rate was tested by applying 3D data compression technology so that data can be transmitted quickly in the field, and technology was developed that can be used by decompressing 3D data compressed in the field. finally, it aims to supplement the technology experimentally developed in this study and conduct additional research to produce it as software that can be used in the excavation site and use it.

Confucianism which pursues the right relationship between person and person, depicts the ideal that moral individuals contribute to community development. In the 16th century, Toegye Yi Hwang, the authority of Korean Confucianism, reflected his educational intentions and interests and made the whole of the body of Confucianism and the whole process of the study into a series of 10 paintings 'Ten Diagrams of Sage Learning'. The purpose of the education which is claimed in the 'Ten Diagrams of Sage Learning' is to become a saint, and it ultimately coincides with the purpose of moral education which is to be introspective and practical moral man. The whole theme of 'Ten Diagrams of Sage Learning' is related to revealing the principles of humanity and morality in order to restore human nature on the basis of piety. Piety(敬) is also a purpose and a method of self-discipline, and is the main content. The method of education for traditional confucianism is aiming for the organic integration of purpose, content and method of education and reveals the consistency of the combination of knowledge and behavior in content and method. Exploring the universal value of traditional culture and re-raising moral culture that is important in traditional education is to discuss that what is valid for the present and the future is derived from the past tradition. That may be useful in solving today's educational problems. Especially, it is very meaningful to adopt a reflective approach to cultivate talented people who can 'realize oneself' and 'care for the community' which is the ultimate goal of education through analyzing the essence of moral education pursued by traditional education.

Research on diagnosing and predicting the response of ecosystems caused by environmental changes such as artificial disturbance and climate change is emerging as the most important issue of biodiversity and ecosystem researches. This study aims to clean, standardize, and provide the results of National Ecosystem Survey which should be considered fundamentally in diagnosing and predicting ecosystem changes in the form of dataset. To refine and clean the dataset we developed a simple verification program based on the fifth National Ecosystem Survey Guideline and applied that program to the data from the second (1997~2005), third (2006~2013) and fourth (2014~2018) National Ecosystem Survey. Data quality control processes were implemented including (1) standardization of terminology, (2) similar data table integration, (3) unnecessary attribute and error elimination, (4) unification of different input items, (5) data arrangement in codes, and (6) code mapping for input items. These approaches and methods are the first attempt propose an option for ecological data standardization in Korea. The standardized dataset of National Ecosystem Survey in Korea will be easily accessible, reusable for both researchers and public. In addition, we expect it will contribute to the establishment of diverse environmental policies concerning environmental assessments, habitat conservation, prediction of endangered species distribution and ecological risks due to climate change. The dataset through this study is open freely online via EcoBank (nie-ecobank.kr) which is the first ecological information portal system in Korea developed by National Institute of Ecology.

The EDucation-research Integration through Simulation On the Net (EDISON) platform, which is a web-based platform that provides computational science and engineering simulation execution environments, can offer various analysis environments to students, general users, as well as computational science and engineering researchers. To expand the user base of the simulation environment services, the EDISON platform holds a challenge every year and attempts to increase the competitiveness and excellence of the platform by analyzing the user requirements of the various simulation environment offered. The challenge platform system in the field of computational science and engineering is provided to users in relation to the simulation service used in the existing EDISON platform. Previously, EDISON challenge servicesoperated independently from simulation services, and hence, services such as end-user review and intermediate simulation results could not be linked. To meet these user requirements, the currently in-service challenge platform for computational science and engineering is linked to the existing computational science and engineering service. In addition, it was possible to increase the efficiency of service resources by providing limited services through various analyses of all users participating in the challenge. In this study, by analyzing the simulation and usage environments of users, we provide an improved challenge platform; we also analyze ways to improve the simulation execution environment.

Eduardo Galeano is a left-wing intellectual who led the criticism and accusations of dictatorship and social absurdity in Latin America. It digs into the truth of hidden history that has not been revealed in official history. He values the memory of history to stop repetition of the unfortunate history of the past. The main research topic of this study, 『The Book of Embraces』, is also an extension of such work. Most of the stories in this work depend on the writer's memory. There is no coherence or integration in the content of the story, and the length of the text is not constant, so it is extremely informal and fragmented. This is a strategy to formally reveal the illogical and irrational reality of Latin America. He analyzes the problems of the separation system prevalent in Latin American society from various perspectives. It separates me and the others as well as the past and the present. It makes the memory of history void and paralyzes the consciousness of history. These systems are fixed for convenient governance. In this situation, the pattern of violence becomes more explicit and broad. The anxiety and fear of the Latin American public become commonplace. It is a reality of enduring daily life without hope. Galeano finds this enduring force in historical memory. He believes that when the past and the present meet and embrace, a new history of the future can be encountered. Galeano does not just criticize reality or cynical attitude but also suggests hope for the future.

The purpose of this study is to present a reflective review of the earth and universe units from the revised elementary curriculum of 2007-2015 and suggest changes in the 2022 revised curriculum. For this purpose, we conducted an FGI with earth science educators and elementary school teachers regarding the content elements and system, the achievement standards and inquiry activity composition, and the vertical and horizontal curriculum connectivity. Free response and weighted hierarchical analysis items were incorporated into the FGI to ensure logical consistency of the inductively derived improvement. This analysis revealed that the composition of units by grade group had been unevenly distributed among each of the "earth systems" until the 2015 revised curriculum was finalized. Furthermore, the basic concept was still insufficient. We suggest that achievement standards centered on the learning content and skills must state specific scientific core competencies, and inquiry activities should include rigorous critical thinking, student written responses, and student inquiry and analysis. In the hierarchical analysis items, FGI emphasized the inclusion of essential content elements rather than reduction of content elements, understanding-oriented concept learning rather than interest-centered phenomenon learning, basic concept division learning before integration between subjects, and expanding vertical-horizontal connectivity rather than repeating and advancing learning. There is a limit to the generalizing the suggestions proposed in this study to the common opinion of elementary earth science experts. However, since the main vision of the 2022 revised curriculum is to gather opinions through educational entities' participation in a variety of educational subjects, it is suggested that our results should be incorporated as one of the opinions proposed for the 2022 curriculum revision.
