This study aimed to identify the development direction of Arduino-based boards relating to artificial intelligence based on social awareness identified using big data analytical methods. For the purpose, big data were extracted through the Textom website, focusing on keywords that included 'Arduino + artificial intelligence' and 'Arduino + AI', and these data were refined and analyzed using the Textom website and the UNICET program. In this study, big data analyses, including frequency analysis, TF-IDF analysis, Degree Centrality analysis, N-gram analysis, and CONCOR analysis, were performed. The analyses' results confirmed that keywords relating to education and coding education, keywords relating to making and experience based on Arduino, and keywords relating to programs were the main keywords used in Arduino- and artificial intelligence-related Internet documents, and clusters were formed based on these keywords confirmed. The social awareness of Arduino and artificial intelligence was evaluated, and the direction of board development was identified based on this social awareness. This study is meaningful in that it identified various factors of board development based on the general public's social awareness, which was evaluated using a big data analysis method. This study may serve as a point of reference for future researchers or developers wishing to understand user needs using big data analysis methods.

Digital transformation refers to the economic and social effects of digitisation and digitalisation. Although digital transformation acts as a useful tool for economic/social development and enhancing the convenience of life, it can have negative effects (misuse of personal information, ethical problems, deepening social gaps, etc.). The government is actively establishing policies to promote digital transformation to secure competitiveness and technological hegemony, however, understanding of digital transformation-related risk issues and implementing policies to prevent them are relatively slow. Thus, this study systematically identifies risk issues of the future society that can be caused by digital transformation based on quantitative analysis of media articles big data through the Embedded Topic Modeling method. Specifically, first, detailed issues of negative effects of digital transformation in major countries were identified. Then detailed issues of negative effects of artificial intelligence in major countries and Korea were identified. Further, by synthesizing the results, future direction of the government's digital transformation policies for responding the negative effects was proposed. The policy implications are as follows. First, since the negative effects of digital transformation does not only affect technological fields but also affect the overall society, such as national security, social issues, and fairness issues. Therefore, the government should not only promote the positive functions of digital transformation, but also prepare policies to counter the negative functions of digital transformation. Second, the detailed issues of future social risks of digital transformation appear differently depending on contexts, so the government should establish a policy to respond to the negative effects of digital transformation in consideration of the national and social context. Third, the government should set a major direction for responding negative effects of digital transformation to minimize confusion among stakeholders, and prepare effective policy measures.

The purpose of this study is to develop a theme-selection activity in 'clothing life' in relation to SDGs(Sustainable Development Goals) for the free semester program. After analyzing the contents of the 'clothing life' area of middle school home economics textbooks based on the SDGs, the content system and learning goals were set. Then a program was developed and the validity and the feasibility of the program were verified. As a result of the analysis of textbooks, the contents of 'clothing life' included all the three basic dimensions of social development, economic growth, and environment protection, yet focus only on 1 or 2 goals of each area. Based on the results of the analysis, a 'Righteous(義) Clothing(衣) Life' program was developed. The developed program consists of teaching-learning process plans and teaching-learning materials in eight class periods, including 'The future everyone dreams of' based on SDG12, 'Two faces of fast fashion' based on SDG1, SDG5, SDG8, SDG10, 'Living as Homoclimatus' based on SDG13, and 'The future we create' based on SDG9 and SDG12. Through the expert evaluation process for the developed program, the program's teaching and learning adequacy and feasibility were reviewed and feedback was actively reflected to correct and supplement the program. Through this study, it is expected that it will contribute to laying the foundation for establishing home economics as a subject that educates citizens who practice sustainable life, and a pivotal subject in education for sustainable development.

At present, we are at the point of change of the 4th industrial revolution era due to the development of artificial intelligence(AI) and rapid technological innovation that no one can predict until now. This study started from the question of 'What role should home economics education play in the era of the Fourth Industrial Revolution?'. The Fourth Industrial Revolution is characterized by AI, cloud computing, Internet of Things(IoT), big data, and Online to Offline(O2O). It will drastically change the social system, science and technology and the structure of the profession. Since the dehumanization of robots and artificial intelligence may occur, the 4th Industrial Revolution Education should be sought to foster future human resources with humanity and citizenship for the future community. In addition, the implication of education in the fourth industrial revolution, which will bring about a change to a super-intelligent and hyper-connected society, is that the role of education should be emphasized so that humans internalize their values as human beings. Character education should be established as a generalized and internalized consciousness with a concept established in the integration of the curriculum, and concrete practical strategies should be prepared. In conclusion, home economics education in the 4th industrial revolution era should play a leading role in the central role of character education, and intrinsic improvement of various human lives. The fourth industrial revolution will change not only what we do, or human mental and physical activities, but also who we are, or human identity. In the information society and digital society, it is important how quickly and accurately it is possible to acquire scattered knowledge. In the information society, it is required to learn how to use knowledge for human beings in rapid change. As such, the fourth industrial revolution seeks to lead the family, organization, and community positively by influencing the systems that shape our lives. Home economics education should take the lead in this role.

This study aims to confirm the effect of the 'Meal and Cooking for Single-Person Households' education program on improving the dietary management competency of high school students. In order to achieve this research purpose, 'Meal and Cooking for Single-Person Households' education program was developed, implemented, and evaluated based on the ADDIE instructional design model. The results of this study are as follows. First, an analysis was conducted on literature and prior research related to the dietary life of single-person households and dietary education programs of the home economics subject. Based on this, the theoretical background for the 'Meal and Cooking for Single-Person Households' education program was established. Then, teaching-learning process plan and student workbooks for a total of 16 unit classes were developed. The expert validity of the program was verified by 6 experts who are current high school home economics teachers and have experience in conducting research related to dietary education programs. As a result, the average of all items was 4.89 (out of 5 points) and the CVI was 0.98, securing very excellent content validity. Second, the researcher directly implemented 'Meal and Cooking for Single-Person Households' education program for 100 students in Y high school located in Sejong city. Considering the school's situation, the 16th session of teaching-learning process plan was shortened to 6th sessions while all the core topics. A survey was conducted on students who participated in the program and the pre- and post- results were analyzed. As a result of the survey analysis, the 'Meal and Cooking for Single-Person Households' education program had a positive effect on improving the dietary management competency of high school students. This study is meaningful in that it has implications for the development of a new subject in home economics in preparation for the high school credit system and improving dietary management competency in accordance with social changes in the era of single-person households, and the 'Meal and Cooking for Single-Person Households' education program developed in this study can be used as a mini-subject in the 2022 revised curriculum.

This study aimed to identify the effects of mothers' variables and present children's variables on subsequent childbirth plan and to explore predictors of subsequent childbirth plan for non-employed and employed mothers. The subjects were 1,635 mothers participating in the Panel Study on Korean Children from 2008 to 2010 and having no subsequent children until 2010 after giving birth to children in 2008. The data were analyzed with descriptive statistics, t test, ${\chi}^2$ test, and decision tree analysis. The main results of this study were as follows. Firstly, mothers' child-rearing stresses, child value, marital satisfaction, social support, present children's birth order and sex influenced mothers' subsequent childbirth plans, whereas mothers' average family income per month did not. Secondly, in the case of non-employed mothers, their present children's birth order and sex, and mothers' child value predicted their subsequent childbirth plan. Specifically, mothers whose present children's birth order and sex was first and female had the highest possibilities of subsequent childbirth plan, followed by mothers whose present children's birth order and sex was first and male, and child value was higher. Thirdly, in the case of employed mothers, their present children's birth order and mothers' marital satisfaction predicted their subsequent childbirth plan. Specifically, mothers whose present children' birth order was first and marital satisfaction was higher had the highest possibilities of subsequent childbirth plan. Finally, the study suggested the role of Home Economics Education in raising the rate of subsequent childbirth.

The purposes of this study are to not only estimate optimal harvests and efforts using the surplus production methods for Spanish mackerel caught by multiple fishing gears, but provide dynamic optimal fisheries management for these gears using the current value Hamiltonian method. To achieve the above purposes this study uses several models such as Gavaris's general linear model for standardizing fishing efforts, surplus production method for estimating biological and technological coefficients, current value Hamiltonian method for estimating dynamic optimal harvest and efforts, and sensitivity analysis for diagnosing economic influences of these fisheries. As a result, this study showed that Spanish mackerel was overfished by multiple fishing gears based on surplus production method and the current value Hamiltonian method. Also, this study found that when the price and cost proportionally changed, the optimal harvest and fishing effort sensitively responded to the stock level of Spanish mackerel. Next, this study suggested that the multiple fishing gears for Spanish mackerel should reduce unnecessary costs such as operating time or inefficient fuel consumption. Finally, this study provided reasons Spanish mackerel should be included in the TAC system in a view of profit maximization based on sustainable use of the Spanish mackerel.

The recent crises of Marxism do not mean Marx’s crisis. Marx said that he was not a Marxist. The purposes of this essay explore (1) the modern identity of the political economy; (2) the possibilities of mutual understanding between neoclassical economics and Marxist economics; (3) problems of the political economy in media and communication industry. I have begged for analytical Marxists, because of their good fruits. They accepted the methods of modern social science and they constituted a tremendous advance in the application of the scientific methods to the study of society. In insisting on micro-foundations(methodological individualism), analytical Marxism distinguished itself from structuralism and functionalism. I appreciate that analytical Marxism has reduced a theory to practice. But the works didn’t listen to everyone(from Marxists to un-Marxists), and explain everything. Making theory with production/consumption, macro/micro, and structure/behavior is a road to the political economy in the long run. It also applies to media and communication industry. The realm of media/communication is broad, which in philosophy, humanities, politics, economics, sociology, and engineering. And media policy is more complicated by politicians who look at the same situation from different angles. By the aid of interdisciplinary research, the political economy of media/communication shall explain at full length.

The current employment status among young home economists and perspectives in occupations for prospective Home Economics graduates were explored in this study which utilized information from 17 to 21 colleges in Korea and colleges in the United States during the five years of 1977∼1981. The Home Economics content areas covered in this study were Clothing and Textiles, Foods and Nutrition, Housing and Interior Design, and Child Development and Family Life. The highest percentage of Korean graduates in Clothing and Textiles was employed either as teachers at the junior high school level or as designers in the clothing and textile industries. Quite a number of the graduates were engaged in further studies at the graduate level. Korean graduates with a master's degree were teaching at the college level and some had furthered their studies at the doctorate level either here or abroad. Koreans with a bachelor's degree in Foods and Nutrition held jobs as teachers in junior high school, dieticians at mass feeding institutions and hospitals, food scientists in food industries, and researchers in institutions. Those with a master's degree were teaching at the college level. Americans with a bachelor's degree worked as dieticians, supervisors in restaurants and institutions, extension workers, researchers at various facilities, teachers and clerks. Americans with a master's or doctorate degree were engaged in teaching at colleges or supervising at research or working as extension specialists. In general, Korean graduates were found to hold positions in less varied areas than their American counter-parts. Among forty-nine graduates those working in their professional field reported less sex discrimination that those working in other fields. The major area of employment in Housing and Interior Design or Home Management graduates in Korea was teaching while in the United States it was extension work, business, governmental work and teaching. It was suggested that in the future, career development in Korea be further explored to include extension service, research, social welfare, financial planning, business, free-lancing, funeral home, home-call, and correctional education. Interviews with executives from 6 business enterprises indicated that most of them were aware of the potential contribution home economists could make for their companies but they expressed a negative attitude towards women in general due to their short stay on the job. Jobs held by Child Development and Family Life majors with a bachelor's degree in Korea were mostly teaching positions in public, junior and senior high school. However, jobs such as nursery school teaching, working in clinical setting, business, and teaching at public, junior and senior high school predominated in the United states. Most Korean graduates with a master's degree were teaching in professional colleges while in the United Stated the job variation among the graduates was rather evenly distributed among teaching at college level, public and high school, nursery school and administration areas. Reports from 7 child development majors on the job indicated that they were paid less that secretarial workers. Only half of them were working in their major area and these expressed satisfaction with their work. Two thirds of the respondents indicated no sex discrimination. It was suggested that in the future Child Development and Family Life majors pursue employment in counseling, guidance, recreation, mass media, administration and outreach work as well as education, research and parent education in services for children, teen-agers, adults and families.

The purpose of this study was to identify the contents that students want to learn the most on Home-Economics. Participants were 710 middle school students(359 boys and 351 girls) from 9 schools located in 4 cities and 5 counties in CholaBukDo. The results are as follows: 1. Of 32 contents on Family life, boys were interested in 'the puberty', 'pregnancy and the ethics on sex', 'social needs', 'the importance of family relationship', and 'adolescents' physical development'. On the other hand, girls were more intered in 'pregnancy' and 'the ethics on sex', 'the puberty', 'development of career consciousness' and 'career preparation', 'the adolescents' physiolosical and physical development', and 'the importance of family relationship'. 2. Of 37 contents of Managing home resource and Consumer life subarea, boys showed their interests on 'environmental problems', 'environmental conservation', 'environmental pollution', 'management of time and work', 'knowledge', 'management of their abilities'. And girls were more interested in 'environmental conservation', 'environmental pollution', 'environmental problems', 'adolescents life', and 'management of time and work'. 3. Of 49 contents on Dietary life, boys were more interested in 'puberty and the development', 'importance of nutriment', 'nutrition and health' and 'smoking and the health'. However, girls were more interested in 'smoking and health', 'puberty and the development', 'the importance of nutriment', 'nutrition and health', 'a realistic plan to reduce the food-based environmental pollution'. 4. Of 40 contents on Clothing life subarea, while boys were interested in 'the suitable cloths on oneself', 'clothing design', 'regulation of temparature', physical protection' 'merchandising for ready-made clothing'. On the other hand, girls were mostly interested in 'the suitable cloths on oneself', and next 'the clothing design', 'merchandising for ready-made clothes','physical protection', and 'the appropriate posture and physical adornment'. 5. Of 18 contents on Residence life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. In general, those middle school students in Cheolabukdo showed the biggest interest on 'Clothing life', 'Residence life' the second, 'Eating life' the third, 'Human development and Family relationship' the fourth, and Management of family resource and Consuming life' was their fifth interest. Such result was consistent with Ⅱ-Rok Park's previous research(1997). Since the participants for this study were sampled form 9 schools located in CheolaBukDo, it is not suitable to apply the results nationwide. The restricted sampling must be considered and further studies are needed to make comparisons among areas.
