Due to unprecedented extreme weather events such as global warming and climate change, many parts of the world suffer from severe pain, and economic losses are also snowballing. In order to address these problems, 'The Paris Agreement' was signed in 2016, and an intergovernmental consultative body was formed to keep the average temperature rise of the Earth below 1.5℃. Korea also declared 'Carbon Neutrality in 2050' to prevent climate catastrophe. In particular, it was found that the increase in temperature caused by greenhouse gas emissions hurts the environment and society as a whole, as well as the export-dependent economy of Korea. In addition, as the diversification of transportation types is accelerating, the change in means of choice is also increasing. As the development paradigm in the low-growth era changes to urban regeneration, interest in idle railway sites is rising due to reduced demand for routes, improvement of alignment, and relocation of urban railways. Meanwhile, it is possible to partially achieve the solar power generation goal of 'Renewable Energy 3020' by utilizing already developed but idle railway sites and take advantage of being free from environmental damage and resident acceptance issues surrounding the location; but the actual use and plan for these solar power facilities are still lacking. Therefore, in this study, using the big data provided by the Korea National Railway and the Renewable Energy Cloud Platform, we develop an algorithm to discover and analyze suitable idle sites where solar power generation facilities can be installed and identify potentially applicable areas considering conditions desired by users. By searching and deriving these idle but relevant sites, it is intended to devise a plan to save enormous costs for facilities or expansion in the early stages of development. This study uses various cluster analyses to develop an optimal algorithm that can derive solar power plant locations on idle railway sites and, as a result, suggests 202 'actively recommended areas.' These results would help decision-makers make rational decisions from the viewpoint of simultaneously considering the economy and the environment.

This study is based on the view point of diglossia that Chinese writing held a higher position than Korean language in the Joseon Dynasty, especially during the 16th century. Diglossic writers were focus on and the implication of diglossia in literacy education was examined. In particular, the diglossic literary features of Korean poetry and songs were examined, with a focus on differences in the authors' gender: female(Hwang Jini and Heo Nanseolheon) and male (Lee Hwang, Jeong Cheol and others). In the case of diglossic literature written by male poets, their Hansi and Sijo had quite different subjects. In addition, their Hansi, which was the exclusive property of noblemen, was largely based on their lives. However, the female poet Heo Nanseolheon covered wider range of subjects and used the first-person point of view, even when the content was not based on her actual life. In particular, she wrote Hansi as lyrics for Korean songs and thus, some of her Hansi can be enjoyed through singing. This differs considerably from the work of male diglossic writers. Furthermore, this tendency can be seen in the history of Hansi after the 18th century. Another female poet, Hwang Jini free from Neo-Confucianism, depicted her free thoughts and expressions in Sijo and reflected various poetic speakers' situations in both Sijo and Hansi. This is especially interesting since women were considered to be of lower social class at that time; these two female poets did not just refuse to follow the writing patterns of male noblemen, they also applied the characteristics of Korean poetry and songs to Hansi and disrupted the traditional characteristics of Hansi. In current education, the 2015 revised national curriculum put emphasize on understanding not only the scope of functional literacy, but also the principle for enhancing critical perception with respect to understanding the ways of communication of power and hierarchical structure. This can be considered a good principle, although mainstream literature does not pay attention to it. In addition, it can be applied through self-internalization and an acceptance of literature in school education by using the spoken language culture that students generally prefer in digital media. Highlighting the perception of advantages and characteristics, when minority statuses are linked to artistic freedoms to flout current prevailing values and cultural tendencies, can enhance not only classical literature literacy but also improve students' characteristics and competency.
