The purpose of this study is to understand the public needs for AI education actively promoted and supported by the current government. In doing so, 11 metropolitan news articles and Twitter posts regarding AI education that have been posted from January 1, 2018 to December 31, 2019 were collected. Then, word frequency analysis using TF(Term Frequency) method and LDA(Latent Dirichlet Allocation) method of topic modeling analysis were conducted. The topics of the news articles turn out to be a macroscopic policy support such as 'training female manpower in the AI field' and 'curriculum reform of university and K-12', whereas the topics of twitter delineate more detailed social perception on future society, such as future competencies and pedagogical methods, including 'coexistence with intelligent robots', 'coding education', and 'humane education competence development'. The findings are expected to be used to suggest the implications for the composition and management of AI curriculum as well as the basic framework of human resources development in the future industry.

This article intends to examine the value of the world citizenship in the perspective from the root meaning that is stressed as the behavior style of Daesoon thoughts in relation with 'desirable attitude of life in education of morality. Traditional root meaning of Daesoon thoughts turned out to be proper moral behavior principle such as Yin Yang harmonious virtue, God Humane keeping unity, and conviviality with regrets settlement. Such three principles of Daesoon Thoughts show the characteristic of global code such as respect of life, solidarity unity, and tolerant trust. To revise the phenomenon of duality, and to realize the human awakening in radically changing reality, we need to cultivate world citizenship based on the root meaning of Daesoon thoughts. Daesoon thoughts covering the East and the West, especially the key features of religion, can cultivate the world view of citizenship in the era of plural society based on folk beliefs toward Gucheon Sangje faith as the essence of the multiplism. The world citizenship of human society is necessary to unite the world in the unified construction cooperative spirits. All beings need to be away from antagonistic confrontation with the practice of mutual conviviality. The diameter of acquired joining world citizenship can have the opportunity to realize of Gucheon Sangje's Heaven and earth construction. The root meaning of Daesoon thoughts can contribute to moral practicality with world citizenship by practice of heavenly truth and human truth. First, cultivating heavenly truth by means of insight can develope the profound world citizenship. Secondly, the solidarity of the public and private can cultivate public citizenship. Thirdly, in the crisis of the mankind, this awakening conviviality can be foundation for world citizenship of public communication. Fourthly, the spirit that would not deceive ownself can be contributed to cultivating the world citizenship by means of the process of internalizing Daesoon thoughts. Nowadays in the plural society demanding world citizenship, the public citizenship can deepen the spirit of respect of life, solidarity unity, and tolerant trust in the process of world citizenship cultivation. In the future, the world citizenship can be deepen the alternative of practice in the continuous cultivation of world citizenship. In this process, we can form the culture of coexistence which can contribute to human society as well as korean society by developing the value of living together happiness through the guide of this phonesis.

A study on the electrolytic dissolution of SUS-304 and Inconel-600 specimen was carried out in neutral salt electrolyte to evaluate the applicability of electrochemical decontamination process for recycle or self disposal with authorization of large amount of metallic wastes contaminated with uranium compounds generated by dismantling a retired uranium conversion plant in Korea. Although the best electrolytic dissolution performance for the specimens was observed in a Na2s04 electrolyte, a NaNO$_3$ neutral salt electrolyte, in which about 30% for SUS-304 and the same for Inconel-600 in the weight loss was shown in comparison with that in a Na$_2$SO$_4$ solution, was selected as an electrolyte for the electrochemical decontamination of metallic wastes with the consideration on the surface of system components contacted with nitric acid and the compatibility with lagoon wastes generated during the facility operation. The effects of current density, electrolytic dissolution time, and concentration of NaNO$_3$ on the electrolytic dissolution of the specimens were investigated. On the basis of the results obtained through the basic inactive experiments, electrochemical decontamination tests using the specimens contaminated with uranium compounds such as UO$_2$, AUC (ammonium uranyl carbonate) and ADU (ammonium diuranate) taken from an uranium conversion facility were performed in 1M NaNO$_3$ solution with the current density or In mA/$\textrm{cm}^2$. it was verified that the electrochemical decontamination of the metallic wastes contaminated uranium compounds was quite successful in a NaNO$_3$ neutral salt electrolyte by reducing $\alpha$ and $\beta$ radioactivities below the level of self disposal within 10 minutes regardless of the type of contaminants and the degree of contamination.
