현재 그리드 컴퓨팅에 관한 연구는 그리드 컴퓨팅 인프라의 성공적인 구축과 함께 그리드 컴퓨팅의 응용분야가 확대됨으로써 그리드 컴퓨팅이 제공하는 고성능 연산 자원뿐만 아니라 대용량의 저장장치와 데이터베이스를 이용하기 위한 데이터 그리드에 관한 연구도 활발히 이루어지고 있다. 하지만 데이터 그리드를 이용하는 응용에서 파일을 이용할 기회가 더욱 많음에도 불구하고 데이터베이스에 관한 연구에 비해 파일 데이터에 관한 연구가 미비한 실정이다. 따라서 본 논문에서는 그리드 컴퓨팅 미들웨어의 표준으로 자리 잡고 있는 OGSA물 기반으로 한 그리드 파일 시스템을 설계한다. OGSA 기반 그리드 파일 시스템은 크게 전통적인 파일 시스템과 같은 단일 뷰를 가능케 하는 명명 공간 서비스, 여러 개의 같은 파일을 단일 파일로 보이게 하는 복제 파일 관리 서비스, 파일의 메타 데이터 정보를 관리하는 파일시스템 정보 서비스, 마지막으로 사용자들과 개발자들이 동일한 접근 방식을 이용하도록 하는 서버${\cdot}$클라이언트${\cdot}$파일 제공자 인터페이스로 구성된다.

The analysis of the progressive collapse resistance of structures is a well-known issue among structural engineers. Large-span reticulated dome structures are commonly utilized in large public buildings, necessitating research into their progressive collapse resistance to assure user safety. The most significant part of improving the structural resilience of reticulated domes is to evaluate their key elements. Based on a stiffness-based evaluation approach, this work offers a calculating procedure for element importance coefficient. For both original and damaged structures, evaluations are carried out using the global stiffness matrix and the determinant. The Kiewitt, Schwedler, and Sunflower reticulated domes are investigated to explore the distribution characteristic of element importance coefficients in the single-layer dome structures. Moreover, the influences of the load levels, load distributions, geometric parameters and topological features are also discussed. The results can be regarded as the initial concept design reference for single-layer reticulated domes.

In this study, we tried to develop STEAM integrated program using virtual reality(VR) equipment and to evaluate the learners' satisfaction in order to cultivate the convergent talent. The pre-test and the post-test were used to compare the mean scores of the assessed candidates and sub-areas. The post-test results were higher than pre-test results. The area with statistically significant mean height was derived as the 'self-concept' area of 'science' which is a sub-area of 'care and communication'.

Recently, we have been listening such a words, that is, the crisis of public education through the mass communication such as newspaper or broadcasting. This means that we didn't have an enough opportunity to think it over about good education programme which the education of school can be normalized or the design of curriculum in the current problems such as overcrowded class, teacher and poor finance which is not still solved. As we know, it is true that the older generation is familiar with the rote learning which was under the control of behaviorism for about three hundred years. Fortunately, The 7th curriculum which had made public by the ministry of education on 30 Dec. 1997 have changed so many things such as real life based or activity based and so on. But it still leaves something to be desired in reflecting the demand of teachers of field. Taking into account this real situation, I have wondered how they run curriculum and how math learning programme of lower grade is different with ours in New Zealand, etc and so I had tried to find some suggestive points through the comparison of curriculum and text between Korea and New Zealand. But, if we want to compare all the strands of curriculum between two countries, it is too global and so in this paper, we deal with only number and operations(number), measurement, figure(geometry), equation and patter(algebra), probability and statistics(statistics) which are dealt with more comparatively in the lower grade of primary school. Because the main purpose of this paper is a comparison and analysis of the curriculum and math learning program of the lower grade in the primary school between two countries and so we compare global characteristics of education system and curriculum between two countries, at first and then we dealt with the very core part of the content of New Zealand curriculum within the ranges of level 1, 2 and 3 and global characteristics of learning program simultaneously.

STEAM and S / W education in public education are effective in fostering talented people and the talents of the 4th industrial revolution era. It is necessary to expand the teachers for this purpose, to find out and apply various learning materials, and to improve education environment for fusion talent education. An open learning platform is effective in reducing private education costs and supplementing public education. Especially, it is useful for flip learning combined with classroom (off-line). In this case, teacher's role can be transformed into active teaching activities and research activities, which can speed up normalization of public education and reduce private education.In particular, the core functions of the MOOC platform for elementary education are 'creative instructional design and contents development function', 'digital teaching and learning curation', 'big data based learner customization', 'learning participation' flip learning and social Learning function.Through this study, it is expected that discussion on the introduction of MOOC for career and admission education for adolescents including elementary education will be established and the Korean youth MOOC platform will be developed and developed as a global advanced model of education democratization.

Particulate matter has emerged as a serious global problem, necessitating highly reliable information on the matter. Therefore, various algorithms have been used in studies to predict particulate matter. In this study, we compared the prediction performance of neural network models that have been actively studied for particulate matter prediction. Among the neural network algorithms, a deep neural network (DNN), a recurrent neural network, and long short-term memory were used to design the optimal prediction model using a hyper-parameter search. In the comparative analysis of the prediction performance of each model, the DNN model showed a lower root mean square error (RMSE) than the other algorithms in the performance comparison using the RMSE and the level of accuracy as metrics for evaluation. The stability of the recurrent neural network was slightly lower than that of the other algorithms, although the accuracy was higher.

The purpose of this study is to develop a sustainable dietary education program using garden vegetables for middle school students. Textbook analysis and demand survey were conducted before developing the program. Ten textbooks of technology and home economics for middle and high school students were analyzed and the results showed that none of the textbooks covered food gardening. Two hundred and six middle school students participated in the demand survey and the results revealed that students lack an understanding of food gardening despite high interest. Therefore, six sessions of a sustainable dietary education program using garden vegetables were developed based on a six-step DESIGN procedure. Then, the content validity of the program was evaluated by three experts and the program was revised based on the results. This dietary education program will lead students to live a sustainable diet, eventually benefiting the health and wellness of individuals, communities and ecosystems.

Purpose: The role of medical staff gained immense significance in the context of the prolonged coronavirus disease (COVID-19) pandemic. However, few studies had explored the impact of simulation-based education on the ability of nursing students to care for the patients of COVID-19. This study provided nursing students with simulation-based education in caring for the patients of COVID-19 and confirmed its effectiveness. Methods: This study used a non-equivalent control group pretest-posttest design. The participants were recruited from the nursing departments of two universities in Korea through convenience sampling. A total of 79 participants were included: 37 in the intervention group and 42 in the control group. The intervention group received four sessions of simulation training based on the National League for Nursing Jeffries simulation theory. Results: The intervention group showed an improvement compared to the control group in terms of knowledge related to coronavirus, confidence in performing infection control skills, and perception of preparedness for caring for the patients of COVID-19, with a high-level of satisfaction and self-confidence in learning. There was no significant difference between the two groups in terms of anxiety. Conclusion: This simulation is expected to be a significant strategy for alleviating the global burden in terms of staff safety and patient outcomes by improving the competencies of prospective medical staff in responding to pandemics.

According to the Fourth Industrial Revolution, SW education is emphasized around the world to educate student with new abilities. Following to these global trends, SW education has become mandatory in Korea's 2015 revised curriculum. However, Korean elementary SW education is focused on the use of block-based programming languages. In addition, the point of view of selecting goals and organizing content of SW Education, the affective domain is ignored and focused only on the cognitive and psychomotor domains. So, this study explored method of SW education using the concept of Team-Shared Mental Model for develop of community capacity and Python, which is textual programming language gaining popularity recently. As a result of performing the post test t-test on two groups with similar Team-Shared Mental Model formation, we found that it was effective in forming a Team-Shared Mental Model of the group applying the SW teaching method suggested in the study.
