This study aimed to provide implications required to establish a content strategy by examining the influencing factors affecting the acceptance of curation services for 320 OTT users, and the main results are as follows. First, innovativeness was found to have a positive effect on performance expectations. Second, innovativeness was found to have a positive impact on the effort expectation. Third, performance expectation had a positive effect on the intention to use continuously. Fourth, it was shown that the effort expectation had a positive effect on the intention to use continuously. Fifth, social influence was found to have no significant effect on the intention to use continuously. Sixth, it was found that the facilitating conditions did not significantly affect the intention to use continuously. The above results can be assessed as the higher the OTT users perceive the performance and effort expectations of the curation service, the higher their intention to continue using them. This study is meaningful in that it verified the factors affecting the intention to use the OTT curation service and expanded the UTAUT model.

Education for Sustainable Development is an imperative mean to achieve the sustainable development which is the key idea that meets the needs of both present and succeeding generations by reconciling environmental protection, social development and economic growth. This study addressed the following question. First, what is the overall structure of the ESD contents presented in the textbooks? Second, How are the sub-contents of ESD distributed in the textbooks? Lastly, How are the ESD contents connected to mathematics in the textbooks? For this purpose, the contents in the elemtentary mathematics textbooks from 1^st to 6^th grades were analyzed at both macro and micro levels through quantitative and qualitative research methods. As results, contents related to environmental, social, and economic dimensions were presented from the first grade. The contents were involved the mathematics content domains of Numbers and Operations, Data and Possibilities, and Patterns. However, the contents were presented intensively in middle and high grades, and environmental topics accounted for a high proportion. Among the activities related to ESD, many were focused on solving problems mathematically while some were presented to solve problems as well as to consider sustainability through the activities. Based on the results, the study aims to provide implications for the direction of mathematics education for sustainable development in elementary school.

Science and technology have led the development of mankind, but have created problems such as natural depletion, climate change, economic inequality and poverty. The purpose of this study is to explore the meaning of early childhood science for sustainable development to solve these problems and to contribute to the harmony of nature and human beings. In order to accomplish this research objectives, 18 experts and 15 teachers were interviewed on the meaning of sustainable development and the directions of early childhood science education for sustainable development. Early childhood science education for sustainable development was categorized as follows. 'Mutual respect between child-teacher-organism', 'developing individual inquiry-based on community consciousness', 'looking at the world with child's eyes', 'deepening and expanding on topics of interest', 'continuous inquiry and commitment', 'conversation and sharing-centered exploration'. By these results, it was concluded that early childhood science education for sustainable development should start from the perspective of children, and was a meaningful process in which children constantly learn about the nature surrounding themselves based on mutual respect.

After COVID-19, interest in "sustainable tourism" increased, and the number of tourists who wanted to experience "sustainable tourism" also increased. However, there is a problem that the programs and methods for 'sustainable tourism' are not specific and diverse. In addition, since most of the interests of "sustainable tourism" focus on "environment" and "carbon neutrality," there are not many programs or government policies that can contribute to the community. Therefore, in this study, news data and review data were analyzed to suggest a method for promoting 'sustainable tourism'. First, in this study, major themes of sustainable travel were derived through news big data analysis. Through this analysis, policy themes and events of 'sustainable tourism' were derived. By analyzing news big data related to "sustainable tourism," we would like to analyze the reasons why sustainable travel has not been activated in Korea. Finally, in order to promote sustainable travel in Jeju island, we analyzed user review data of Jeju local currency, and propose a idea to coexist with the local community.

2014년 주택시장은 초반에는 소폭 상승 하락을 거듭하지만 시간이 지나면서 지역별, 규모별 차별화가 심화될 것으로 전망된다. 지역별로는 초과공급이 상대적으로 심한 수도권에 비해 비수도권의 강세현상이 지속될 전망이다. 규모별로는 핵가족화, 고령화 등으로 인하여 가구의 다운사이징 현상이 뚜렷해지면서 중소형 강세, 대형 약세 현상이 지속될 것으로 보인다. 한편 2014년에는 매매시장 불안과 연관된 전세수요가 지속되면서 전세시장 불안도 지속될 가능성이 크다. 여기서는 현대경제연구원의 '2014년 주택시장 전망과 시사점' 보고서를 통해 최근 주택시장 흐름과 주택 시장 주요 수급여건을 분석한 뒤 2014년 주택시장의 특징에 대해 살펴본다.
