This study was conducted to evaluate the effect of several fungicides and growth regulators on rice seedling growth and damping-off in seedling boxes for machine transplanting. Fungicide treated plots were better seedling growth, shoot regrowth, rooting ability, change of moisture content than those of nontreated plot. Metalaxyl application of Samgangbyeo and SF8002 application of Nagdongdyeo apparently increased plant height, length of the third leaf and fourth leaf. And metaiaxyl application highly increased dry weight. Fungicide treated plots were highly effective in reducing the incidence of damping-off. Benzyladenine application of Samgangbye and $GA_3$ application of Nagdongbyeo apprently increased plant height. But ABA application highly decreased plant height. ABA application and aCE application resulted in highly increased rooting ability. Fungicide and $GA_3$ treated plots, Metalaxyl and growth regulator treated plots resulted in highly increased plant height. I soprothiolane and growth regulator treated plots resulted in decreased plant height. Dachigaren and lAA treated plot apprently increased dry weight and shoot dry weight/plant height. Fungicide and growth regulator treated plots were highly effective in reducing the incidence of damping-off.

The purpose of this study is to review and draw lessons from the case of Family and Consumer Sciences(FCS) curriculums in Ohio and to provide implications to the designing of HE elective courses for high schools in Korea. For this, 19 curriculum documents that are available from the website of the Ohio Ministry of Education were analyzed. As a result of the analysis, the following conclusions were drawn: First, following the example of the Ohio Pathway which was developed in consideration of the characteristics of the field, college admission, student's interests, and the societal change, it is recommended that Korean HE curriculum consider developing HE Pathway that reflects the characteristics of Korean HE education system. Second, Ohio's FCS curriculum offers a well-structured system consisting of total 18 courses and contents within the four broad FCS Pathway themes. Thus, it is suggested that the Korean Home Economics Education Association organize a task force to develop 'HE Pathways'-'College majors'-'Elective career focused courses', and student-centered career exploratory elective courses focusing on the students' needs. Third, it is necessary for HE teachers and professors to newly develop basic elective courses which lays the foundation for understanding of Home Economics and help students to follow advanced HE elective courses. Lastly, there is a need for designing career-focused elective courses that can provide practical resources for the college admission process by interviewing college admission officers, education specialists, career counselors, college admission specialists, home economic professors and teachers.

Of all the 55 security departments in colleges, the information security departments occupies the majority of 45. Though existing security focused too much on information security, a new research stream on industrial security from a perspective of convergence has emerged. Since the first department of industrial security was established in a college in 2014, the total of four departments have been established until 2018. A new discipline to solve the existing problems and an opportunity to cultivate industrial security professionals have been greatly appreciated; however, the definition of industrial security is not yet specific, and more discussions on education categories and subjects with a focus on the characteristics of convergence are needed. The demand for industrial security professionals has gradually increasing and the departments of industrial security have been established to meet the demand. It is necessary, in this circumstance, to find out how the industrial security departments are teaching students. To this end, the purpose of this article is to deliver an overview of the educational curriculums of the four industrial security departments. This study analyzed 127 subjects in the curriculums, categorized educational areas, and employed Social Network Analysis to understand the relationships between subjects of each departments.

In order for young people to be interested in tradition, a specialized experience program that can be frequently encountered is needed. We have developed an after-school traditional gift-wrapping design program in relation to the subject of home economics for the purpose of enabling students to become interested in tradition and deepen their traditional knowledge. The research process was comprised of analysis, development, and evaluation. We analyzed the home economics curriculum, authentic designs from blogs and department stores along with books published by gift-wrapping associations, and interviews with three gift wrapping specialists. Contemporary traditional packaging design is not limited to the reproduction of the traditional design but also creates designs that strongly express unique Korean identity using traditional symbol patterns, colors, traditional decorations, and small items along with modern materials. A 16-week after-school program was developed based on the analysis results. After the implementation of the after-school program in a middle school, survey results showed students who were indifferent toward tradition showed interest and acquired a positive image towards tradition.

Data science starts with small data analysis and includes machine learning and deep learning for big data analysis. Data science is a core area of artificial intelligence technology and should be systematically reflected in the school curriculum. For data science education, The Entry also provides a data analysis tool for elementary education. In a big data analysis, data samples are extracted and analysis results are interpreted through statistical guesses and judgments. In this paper, the big data analysis area that requires statistical knowledge is excluded from the elementary area, and data science education examples focusing on the elementary area are proposed. To this end, the general data science education stage was explained first, and the elementary data science education stage was newly proposed. After that, an example of comparing values of data variables and an example of analyzing correlations between data variables were proposed with public small data provided by Entry, according to the elementary data science education stage. By using these Entry data-analysis examples proposed in this paper, it is possible to provide data science convergence education in elementary school, with given data generated from various subjects. In addition, data science educational materials combined with text, audio and video recognition AI tools can be developed by using the Entry.

As the core technology of the Fourth Industrial Revolution, AI is applied to various fields of society(e.g. politics, culture, industry, economy, etc.) and causes revolutionary changes. Students who will lead the age of AI need the ability to recognize social changes due to AI, acquire AI related knowledge and utilize AI in various situations. However, it is difficult for elementary school students to understand the concept and principles of AI. Therefore, this study developed an AI education program by selecting educational contents and methods appropriate to the level of elementary school students, and investigated the educational effects of the program by applying it to an actual educational setting. The content selected in this study is 'Social Awareness on AI', 'Understanding AI' and 'Utilizing AI', and eight content elements were selected. To help students learn AI easily and pleasantly at their level, activity-centered education, convergence of subjects and project-based learning were selected as instructional methods, and 20 sessions of education program were developed and implemented. In addition, the effects of the program were analyzed concerning 'perception on AI', 'convergent thinking', 'creative problem-solving' and 'collaboration capability', and positive changes were verified for all four aspects.

The purpose of this study was to develop a sustainable dietary education program for middle school home economics subject using a teaching strategy to improve the empowerment of adolescents and to verify and evaluate the effectiveness of the program. To achieve the purpose of this study, the program was developed and evaluated according to the ADDIE teaching design model. The contents related to the dietary area were extracted from the technical & home economics curriculum of the 2015 revised middle school and SDGs, and their relevance was analyzed to select the contents of dietary education. The program developed based on the analysis results is 'dietary life together' and consists of five learning topics: 'living together in the global village', 'maintaining healthy diet', 'creating a dietary culture together', 'living with nature and people', and 'maintaining a safe diet'. As a strategy for improving empowerment, we presented four situations, each of which represents value judgment, prediction of results, responsible behavior choice, and decision making. The developed program was reviewed by experts and applied to 17 unit classes for 17 weeks (1 unit hour per week) to the third graders of middle schools in Gyeonggi-do. Significant differences were found between before and after the class measurements of the personal empowerment and the political and social empowerment, which shows the classes were effective in improving empowerment. However, since there was no significant difference in interpersonal empowerment before and after the program, suggestions were made to utilize strategies to facilitate discussion and cooperative learning when implementing the program. The students who participated in the class evaluated the program positively as a whole. The program was evaluated to have helped the students believe they could change society through solving dietary problems.
