Product Certification Marks can be used as reliable information in terms of product quality to consumers. This study focuses on how each product attitude of consumers in Korea and China can be changed depending on attachment of product certification mark. Based on nations, product certification marks, and price levels, eight types of questionnaire are distributed and collected where the respondents are allowed to answer product attitudes of two different products in oder to minimize the effect of the product characteristic. As a result, the product attitude of Korean consumers has been showed to more depend on product certification mark than that of Chinese consumers does. The moderating effect of price has been stronger on Chinese consumers than on Korean consumers, and in the case of high price there has been a distinct gap between two countries. This study has its meaning in the way of that the product certification mark has been considered in relation to price level and differently affected product attitude between two countries.

This study aims at analyzing 6 OECD countries' (Australia, New Zealand, Sweden, Norway, England, South Korea) national early childhood care and education curriculum (framework) based on the perspectives of its implementation. Its design and development always focus on how the national early childhood education and care curriculum will be applied in the early childhood settings in a correct and faithful way. As a result, teachers are considered the user or deliverer of the national curriculum rather than the one who interprets it and construct their own curriculum in accordance with their students. Five OECD countries which have achieved an integrated system between early education and care systems, take the constructive view of designing and applying the national curriculum. Accordingly, a national early childhood education and care curriculum within an integrated system should be developed in Korea, in order to accept the constructive view of curriculum development and application.

In relation to differentiated mathematics education, Russia has a longer experience in research and practice than Korea. The mathematics curriculum for 10-11 grades currently in use in Russia is a level-specific curriculum and consists of a basic level and an advanced level. And in Russia mathematics textbooks for 10-11 grades are also textbooks for each level. In this study, we analyzed basic level textbook and advanced level textbook written by the same author group among the textbooks 'Algebra and Introduction of Mathematical Analysis' of the 10th grade in Russia. To analyze the main learning contents and textbook descriptions that were added in advanced level the 'real numbers' and 'complex numbers' sections were studied. The main contents of basic and advanced level textbooks for 'functions', 'trigonometric functions', 'trigonometric equations', 'conversions of trigonometric expressions', and 'derivatives', which are included in both basic and advanced textbooks were compared and analyzed, and the descriptive characteristics of the definitions and theorems presented in the two levels of textbooks were also compared and analyzed. From the results of this study, it is expected that various information on the contents of various level textbooks of mathematics, the differences between textbooks for each level, and strategies for the composition of textbooks for various level can be accumulated.

The purpose of this study was to measure middle and high school students' stage of concern(SoC) and their level of use(LoU) on the self-directed learning in science learning based on the CBAM(Concern-Based Adoption Model). Additionally, this research was designed to analyze the difference between the degree of students' SoC and their LoU according to the their background variables. For this, 440 middle and high school students participated in the research. The results of this study were as follow: Firstly, since the students' SoC and LoU about the self-directed learning in science learning are low(Stage0 : awareness and Level II : preparation), we should draw students' immediate concern by developing training programs that would enable them to actually participate in the process of implementing the self-directed learning. Secondly, the students' SoC and LoU on self-directed learning in science learning vary depending on their residence, gender, and grade. This is the reason why we have to develop customized training programs on self-directed learning that suits their background. Thirdly, it shows that students, who have higher concern on self-directed learning in science learning, implement it better than those who are not concerned with it at all. It implies that we need a training program that considers both the students' concern and implementation on self-directed learning in science learning.

The purpose of this study is to assess the smart city for major cities in Korea. The assessment indicators are based on the STIM structure (Service, Technology, Infrastructure, and Management Layer Architecture) of the Multi-Layered Smart City Model. Assessment indicators are established through smart city concepts, case analysis, big data analysis, as well as weighted through expert AHP survey. For the assessment, seven major metropolitan cities are selected, including Seoul, and their data such as KOSIS, KISDISTAT from 2017 to 2019 is utilized for the smart city level assessment. The smart city level results show that the service, technology, infrastructure, and management levels were relatively high in Seoul and Incheon, which are metropolitan areas. Whereas, Busan, Daegu, and Ulsan, the Gyeongsang provinces are relatively moderate, while Daejeon and Gwangju, the South Chungcheong region and the Jeolla provinces, were relatively low. The overall STIM ranking shows a similar pattern, as the Seoul metropolitan area smart city level outperforms the rest of the analyzed areas with a large difference. Accordingly, balanced development strategies are needed to reduce gaps in the level of smart cities in South Korea, and respective smart city plans are needed considering the characteristics of each region. This paper will follow the literature review, assessment index establishment, weight analysis of assessment index, major cities assessment and result in analysis, and conclusion.

This paper proposes a method to establish an optical lifetime maintenance strategy for deteriorating bridges in consideration of life-cycle performance and cost. A program is developed based on the proposed method, which can generate optimum maintenance scenarios not only at the individual member level but also at the system level of the bridge. By applying the developed program is studied through the comparative analysis of maintenance strategies generated at each level. According to the results of comparison between maintenance strategies of the member-level analysis and system-level analysis. It is expected that the establishment of a maintenance strategy through the bridge system-level analysis considering target, members reflects practical and reasonable results.

This study compared levels of mathematically talented students' statistical thinking with those of non-talented students in statistical modeling and sampling distribution understanding. t tests were conducted to test for statistically significant differences between mathematically gifted students and non-gifted students. In case of statistical modeling, for both of elementary and middle school graders, the t tests show that there is a statistically significant difference between mathematically gifted students and non-gifted students. Table of frequencies of each level, however, shows that levels of mathematically gifted students' thinking were not distributed at the high levels but were overlapped with those of non-gifted students. A similar tendency is also present in sampling distribution understanding. These results are thought-provoking results in statistics instruction for mathematically talented students.
