This study collects social data and academic research data from portal sites and RISS, and analyzes TF-IDF, N-Gram, semantic network analysis, and CONCOR analysis to analyze the social awareness and current aspects of 'AI Literacy' and 'AI Convergence Education'. Through this, we tried to understand the social awareness aspect and the current situation, and to suggest implications and directions. In the social data, the collection of 'AI Convergence Education' was more than twice that of 'AI Literacy', indicating that awareness of 'AI Literacy' was relatively low. In 'AI Literacy', the keyword 'human' in social data showed no cluster to which it belonged, indicating a lack of philosophical interest in and awareness of humanities and AI. In addition, the keyword 'Ministry of Education' showed high frequency, importance, and centrality of connection only in the social data of 'AI convergence education', confirming that 'AI convergence education' is closely related to government policy.

Consumer awareness of current food labeling system and new nutrition labeling system which the government considers to adopt widely was assessed, from May to June in 1994, for 423 adults living in Seoul. Being highly conscious of food safety, they thought the current food label did not provide sufficient information. Dissatisfaction with the current system was shown higher in the female, young, or unmarried strata. The need for nutrition labeling system was widely recognized by 82% of total respondents regardless of sex, level of education, monthly income, and marital status. Although some expressed worries about proper management of the system, most of the respondents answered that the system would benefit them after all. In this connection, 59% of the respondents showed willingness to accept a price increase to be entailed by nutrition labeling. Nutrition informations that, they thought, should be covered were: calorie>minerals>cholesterol>protein>vitamins>fat>sodium. Additional labeling informations they called for were nutrient contents>RDA percentage>specific statement on reinforced or eliminated nutrients.

The purpose of this study was to survey the status of the operation of site-based environmental education(EE) programs. This study surveyed 165 schools and organizations that operated site-based EE program in 2000 using a mail questionnaire and interviews. The response rate was 43%. The result indicated that awareness, participation, and attitude were considerably addressed, while knowledge and skills were addressed to a lesser degree. There were some difficulties in motivating students and in considering the developmental stage of participants. For programing the site-based EE, financial support and expert knowledge of EE were needed most of all. Learning materials for various and hand-on activities were also needed. The affective domain, such as awareness and attitude, showed marked improvement in the outcomes of the programs. Direct experience and sensitivity, connection with school education, regional characteristics were sufficiently addressed in the programs, while cultural aspects, fairness, originality, and accuracy were not. Flexibility in performing the programs and less rigidity of report on operations were needed. Through the discussion of the results, some improvements for the operation of site-based EE program were suggested.

The construction industry is considered the most hazardous industry globally. Therefore, safety education is crucial for raising the safety awareness of construction workers working at construction sites and creating a safe working environment. However, the current safety education method and tools cannot provide trainees with realistic and practical experiences that might help better safety awareness in practice. A metaverse, a real-time network of 3D virtual worlds focused on social connection, was created for more interactive communication, collaboration, and coordination between users. Several previous studies have noted that the metaverse has excellent potential for improved safety education performance, but its required functions and practical applications have not been thoroughly researched. In order to fill the research gap, this paper reviewed the potential benefits of a metaverse based on the current research and suggested its application for safety education purposes. This paper scrutinized the metaverse's key functions, particularly its information and knowledge sharing function and reality capture function. Then, the authors created a metaverse prototype based on the two key functions described above. The main contribution of this paper is reviewing the potential benefits of a metaverse for safety education. A realistic and feasible metaverse platform should be developed in future studies, and its impact on safety education should be quantitatively verified.

Awareness that smartphones can be used as tools for criminal activity is prevalent in many organizations, but the functionally smartphone-like smartwatch's potential as a criminal tool is being overlooked. Considering this situation, this research verifies the possibility of information leakage through an insider's smartwatch in a situation where smartphones are controlled by security regulations and technologies, but smart watch are not. By analyzing information related application usage and Wi-Fi connection generated in the smartwatch during the verification process, forensic information and limitations are identified. Finally, this research proposes preventive methods to prepare for potential smartwatch-related crimes, and reconsiders awareness of the possibility of using smartwatches as criminal tools.

Recently, makers who do not have huge production equipments and who actually make products that they thought by utilizing digital production tools are emerging as new trends. As these makers shared how to make products, the 'maker movement', an open source manufacturing movement, spread. In the case of the domestic market, the maker movement is being activated through the government's policy support. However, compared to developed countries, there is not enough awareness and environment of maker culture, and only open platform hardware and software are used without specialized education / development equipment or kit for maker. Therefore, in this paper, we implement a MQTT protocol based Internet object maker kit for real service interworking rather than simple data connection through hardware connection.

The government is in the process of pursuing various resident-driven rural development projects for rural development. Accordingly, the government is promoting various software projects to enhance social capital in order to effectively involve residents in rural development projects. However, residents' participation in rural development projects is still passive, while passive residents' involvement creates various problems such as conflicts among residents in the process of project implementation and poor operation after project implementation. This study is intended to be a basis for inducing voluntary community participation in rural development projects by disclosing the intention of residents to participate in the community's internal solidarity with social capital and connection with external communities. According to the analysis of 195 rural residents, three groups were divided according to the level of social capital awareness. While individualist groups with low integration and social capital were 25.1%, they were more integrated, but the average family-oriented group was 42.5%, and social-development groups with high integration and linked social capital were 32.3%. This study is meaningful in that it revealed that the social capital of the resident community is an important factor in both the internal solidarity (integrity) and the external community connection (connectivity) in the rural area development project.

This study would understand the overall perception of our society about public libraries, analyzing the texts related to public libraries, utilizing the semantic connection network & sentiment analysis. For this purpose, this study collected data from the last five years with keywords, 'Library' and 'Lifelong Learning Center' from January 1, 2016 through November 30, 2020 through the blogs and cafés of major domestic portal sites. With the collected data, text mining, centrality of keywords, network structure, structural equipotentiality, and sensitivity analyses were conducted. As a result of the analysis, First, 'reading' and 'book' were identified as representative keywords that form the social perception of public libraries. Second, it turned out that there were keywords related to the use of the library and the untact service due to the recent spread of COVID-19. Third, in seeking a plan for the development of public libraries through the keywords drawn to have positive meanings, it is necessary to create continuous services that can form a new image of the library, breaking away from the existing fixed role and image of the library and increase the convenience of use. Fourth, facilities and facilities for library services were recognized from a neutral point of view. Fifth, the spread of infectious diseases, social distancing, and temporary closure and closure of libraries are negatively related to public libraries, and awareness of librarians has been identified as negative keywords.

We are to introduce an example of ESD in connection with SDGs through liberal arts courses opened at the College of Education. We analyzed the awareness of the carbon footprint expressed by 42 preservice teachers in a class designed in connection with SDGs 13 goal, 'climate action'. The pre-service teachers wrote a carbon diet diary, a checklist for the level of practice that emits carbon in daily life, and freely expressed the source and proportion of their carbon emissions through the carbon footprint drawing activity. In items of electricity use, public transportation use, and garbage disposal, the level of practice was positive, but water use was analyzed in a negative way. The pre-service teachers who expressed the carbon footprint in 2-3 items reached a majority, showing limitations in recognizing the carbon emission situation in their daily life. Pre-service teachers will be the main actors of education on the environmental issues of the earth at the school site, and the carbon literacy of pre-service teachers will directly or indirectly affect students. We hope that various ESD programs linked to the 17 SDGs will be developed and applied to the educational field to contribute to sustainable global environmental education.

In this paper, we introduce a comprehensive design methodology of Radial Basis Function Neural Networks (RBFNN) that is based on mechanism of clustering and optimization algorithm. We can divide some clusters based on similarity of input dataset by using clustering algorithm. As a result, the number of clusters is equal to the number of nodes in the hidden layer. Moreover, the centers of each cluster are used into the centers of each receptive field in the hidden layer. In this study, we have applied Fuzzy-C Means(FCM) and K-Means(KM) clustering algorithm, respectively and compared between them. The weight connections of model are expanded into the type of polynomial functions such as linear and quadratic. In this reason, the output of model consists of relation between input and output. In order to get the optimal structure and better performance, Particle Swarm Optimization(PSO) is used. We can obtain optimized parameters such as both the number of clusters and the polynomial order of weights connection through structural optimization as well as the widths of receptive fields through parametric optimization. To evaluate the performance of proposed model, NXT equipment offered by National Instrument(NI) is exploited. The situation awareness system-related intelligent model was built up by the experimental dataset of distance information measured between object and diverse sensor such as sound sensor, light sensor, and ultrasonic sensor of NXT equipment.
