The abilities to effectively use and create technology to solve complex problems are the new and essential literacy skills of the twenty-first century. Digital literacy is an essential tool to support other subjects and all jobs. The digital literacy requires several thinking skills, an awareness of the necessary standards of behaviour expected in online environments, and an understanding of the shared social issues created by digital technologies. The government tried to cultivate communication ability to solve various problems creatively and efficiently through software education in the 2015 revised national curriculum and to raise communication ability and community consciousness through collaborative problem solving process. In this paper, we analyze whether the 2015 revised curriculum can develop digital literacy ability through educational contents of software curriculum.

This study explores the social phenomenon of the universalization of one-person households through a literature analysis and text mining in order to explore a future direction for Home Economics Education(HEE) development in the one-person household era. From 2010 to 2018, texts from newspaper articles and book content of one-person households were analyzed through R program. The results of the study are as follows. In order to develop students' competency to live a happy life in the one-person household era, it is necessary to: (1) expand the preemptive and collaborative research of HEE, (2) develop and operate a curriculum to raise the living competency to live alone, (3) expand opportunities for secondary school students as well as off-campus youth, middle-aged, and elderly students, and (4) develop various HEE's elective curriculum focusing on the ability to live as one-person household. Also, (5) in order to overcome the psychological and social poverty and isolation of one-person households, HEE should strengthen the learner's ability to form relationships through self-esteem, care of others, community life, communication and conflict resolution education. In conclusion, HEE's independent living competency, relationship formation competency, and practical problem solving competency are all necessary competencies to live in one-person households. In this study, it is meaningful to suggest a future direction for HEE and to use new research methods such as word cloud techniques in the absence of HEE's previous research in relation to the increase of one-person households.

Smart City is gaining attention with the advancement of Information and Communication Technology (ICT). ICT provides the basis for smart city foundation; enables us to interconnect all the actors of a smart city by supporting the provision of seamless ubiquitous services and Internet of Things. On the other hand, Crowdsourcing has the ability to enable citizens to participate in social and economic development of the city and share their contribution and knowledge while increasing their socio-economic welfare. This paper proposed a hybrid model which is a compound of human computation, machine computation and citizen crowds. This proposed hybrid model uses knowledge-based crowdsourcing that captures collaborative and collective intelligence from the citizen crowds to form democratic knowledge space, which provision solutions in areas of civic innovations. This paper also proposed knowledge-based crowdsourcing framework which manages knowledge activities in the form of human computation tasks and eliminates the complexity of human computation task creation, execution, refinement, quality control and manage knowledge space. The knowledge activities in the form of human computation tasks provide support to existing crowdsourcing system to align their task execution order optimally.

With the development of IoT and artificial intelligence, location-based services are getting more and more attention. For solving the current problem that indoor positioning error is large and generalization is poor, this paper proposes a Model Stacking Algorithm for Indoor Positioning System using WiFi fingerprinting. Firstly, we adopt a model stacking method based on Bayesian optimization to predict the location of indoor targets to improve indoor localization accuracy and model generalization. Secondly, Taking the predicted position based on model stacking as the observation value of particle filter, collaborative particle filter localization based on model stacking algorithm is realized. The experimental results show that the algorithm can control the position error within 2m, which is superior to KNN, GBDT, Xgboost, LightGBM, RF. The location accuracy of the fusion particle filter algorithm is improved by 31%, and the predicted trajectory is close to the real trajectory. The algorithm can also adapt to the application scenarios with fewer wireless access points.

This study aims to verify the effects of the sewing practice class, developed for the cultivation of creativity and personality, the two qualities that the Korean Department of Education tried to emphasize in 2009 national curriculum. We conducted a single-group pretest-posttest experiment with the developed sewing practice class as a treatment. Results are as follows. First, the comparison results of before and after the developed sewing practice class showed that there were meaningful differences in creativity and its subfactors such as divergent thinking skill, problem solving ability, open-mindedness and patience. This is because in-class activities such as coming up with ideas by group discussion, creative activities and problem-solving experiences make the students be aware that they are the hosts of the class. It also affected their abilities of producing creative ideas and solving problems proactively. Second, the developed sewing practice class had an impact on students' personality and its subfactors like responsibility, diligence, consideration, communication skill, and collaborative ability. This practice class is based on personal activities which lead to the completion of the group assignment. This has not only emphasized individual responsibilities, but also highlighted the completion of group work and encouraged the flow of communication and cooperation among students. As a result, we concluded that this practice class helped nourish the participating students' personality.

Excessive cognitive burdens caused by learning grammar should be reduced to cultivate high-level thinking skills in students through programing education. To this end, various educational programing languages have been developed. In recent years, block-based App Inventor that can used in real life have been introduced. This study intends to suggest an educational environment in which programing can be utilized as a leading problem solving tool by designing and producing an app that can be easily used by students in their real life. In particular, given the developmental phase of elementary school students, specific operational activities are important. For this reason, an App Inventor that can be proposed to enable dynamic interactions with the real world based on various smartphone sensors during the process of programing has significance as an educational programing language for elementary school students. In this regard, this study designed App Inventor programing education for elementary school students, which can be used in their daily life. The results of applying the education in fifth graders showed its positive effects on learning programing. LT collaborative learning where the students cooperated with each other, the theme of learning, which enables the utilization of various smartphone sensors in real life, and the app inventor may have generated and sustained the students' interest and attention.

This study suggests a Korean fashion design education model through a comparison of the fashion design curriculum and education systems in the USA, Europe, and Korea. For this, a case study of fashion design curriculum and education systems in the USA was performed with literature reviews about education methodology and design process to develop creativity, following the prior study, A Comparative Study on Fashion Design in Europe and Korea. For the case study, 12 superior fashion design education institutions in the USA were chosen from fashionista (N.Y.) and the goals, the emphases, the constitution of the online curriculum of each undergraduate fashion design course were examined. As a result of this study, Korean fashion design education model (1+2.5+0.5 model), was proposed by integrating the education systems of the USA and Europe, as follow: First, Korean fashion design education institutions need to be characterized and the departments/majors should be gradually specialized by the major. Second, foundation courses prior to undergraduate courses or during the 1st year should be established to result in a multi- disciplinary basic education. Third, a project based major needs to be performed that connects fashion design subjects with their related subjects for 2 and a half years as of the $2^{nd}$ year. These projects can be progressed by problem-solving design process of problem-identification and brainstorming-research, analysis-design concept-design ideation, selection-design development, implementation-critical evaluation and solutions. Fourth, collaborative projects or integrated courses with related Liberal Arts or other art and design majors should lead to muliti-discilplinary education. Fifth, the chance of increased active industry-academy collaboration and actual employment or enterprise can be facilitated by the establishment of only the courses related to domestic or international internships during the $2^{nd}$ semester of the $4^{th}$ year.

The aims of this paper were to review the usable possibility of the educational App Inventor Program in the field of programming education and to develop programming teaching materials that can overcome limitations of the established programming instruction. The study showed that the learners' motivations were strengthened through smart device programs. Containing the elements of STEAM, the teaching materials were developed for the logical and systematic learning that deals with elementary students' real-life situations, and that helps children follow the procedures of software development. By introducing the Waterfall Model to the process of programming, students are able to follow the software developers' thinking process. In addition, beyond the simplistic programming language and simply acquiring related knowledge, the App Inventor programming was designed to enhance students' higher-order thinking skills such as creativity, problem solving ability, collaborative thinking, and so forth.

The convergence and consilience in education (hereafter, interdisciplinary education) is receiving great attention from societies. This study aims to investigate the works of scientists and artists who have intended to combine science with the arts in the modern era, to take into account the socio-philosophical setbacks during the period, and to suggest pedagogical implications of science education as interdisciplinary education. The concept of interdisciplinary education stems from Plato's thought, idea, as a comprehensive and invariant truth. The renaissance, full of enrichment about scientific achievement, was based on Neo-Platonism pursuing holistic-synthetic approach. During the time, scientists presented in this study tried to find comprehensive principles and borrow useful method from the arts. In such a context, scientists not only made use of the arts for expression of scientific knowledge, but also drew conclusion by analogical reasoning between science and the arts. Artists, as well, relied upon anatomy and optics especially, to elaborate linear perspective and even developed their own scientific knowledge through personal experience. Hence, contemporary science education should encourage students to hold a holistic viewpoint about science and the arts, articulate explicit goals and outcomes as interdisciplinary education, implement meta-disciplinary instruction about science and the arts, and develop assessment framework for collaborative learning. There may be good examples for inter-disciplinary education as listed: illustrating scientific ideas through the arts and vice versa, organizing collaborative works and evaluations criteria for them, and stressing problem solving on a daily basis.
