The interaction between student and school levels should be considered to understand and examine equity in education. For this reason, we included the socioeconomic composition of schools to scrutinize the equity related to students' socioeconomic status and mathematical literacy in Korea. We applied the hierarchical linear modeling approach to the Programme for International Student Assessment (PISA) 2015 data for binational comparison between Korea (5,548 students from 168 schools) and the U.S. (5,217 students from 161 schools). The findings show that school-level achievement and the socioeconomic composition of schools cannot be ignored to understand Korean students' achievement gap between high and low socioeconomic status. In addition, U.S. students from low socioeconomic status were likely to have similar mathematics literacy scores. These findings indicated that inequity in Korean mathematics education could be intertwined with the characteristics of Korean students like high demands for supplementary private education and school characteristics like curriculum selection. This research also reminds mathematics educators that people should not simply mimic other education systems to resolve education issues in their own system.

The purpose of this study is to examine the causal relationship of related variables in order to promote entrepreneurship, which is one way to support the economic independence and stable settlement of North Korean defectors. This study is firstly to examine the influence of individualism and collectivism on entrepreneurial intentions, and secondly, to examine the mediating effect of social adaptability in the relationship between socialist value system and entrepreneurial intention. To this end, a survey was conducted on North Korean defectors, and the empirical analysis target was 223 North Korean defectors. For the verification of the causal relationship between personal disposition and entrepreneurial intention, and the causal relationship between value system and entrepreneurial intention PLS was used. And PROCESS for SPSS Macro was used to verify the mediating effect of social adaptation in the relationship between the value system and entrepreneurial intention. Looking at the results of the empirical analysis, the extraversion factor was found to have a positive effect on the entrepreneurial intention level of North Korean defectors, and the self-fulfillment desire factor was found to have a positive effect on the entrepreneurial intention. It was also found that individualist values have a positive effect on the entrepreneurial intentions of North Korean defectors, and collectivist values do not have a significant effect on the entrepreneurial intentions. As a result of examining the mediating effect of social adaptability between individualism/collectivism and entrepreneurial intention in this study, it was found that individualist value has a direct impact on entrepreneurial intention without engaging social adaptability.

This study analyzes the effect of poverty on child development outcomes including academic achievement, self-esteem, depression/anxiety, attention problems, aggression, and delinquency. The poverty experiences among elementary school children are longitudinally observed during 3 years between the 4th grade and the 6th grade. When development outcomes are compared among persistently poor children, transitory poor children, and non-poor children, academic achievement is found to be significantly different. The analyses of the relationships between the poverty status and developmental trajectories show that academic achievement among non-poor children has improved over time, while the level of poor children's achievement has decreased. The result also shows that problematic behaviors such as attention problems, aggression, delinquency has improved over time among all the children. Yet, the gap between poor and non-poor children has not decreased. The multivariate analyses indicate that the effect of poverty remains statistically significant only for academic achievement after children's individual and familial characteristics are controlled. Past experiences of poverty in addition to the current poverty affect academic achievement and persistent poverty has a stronger effect than transitory poverty on academic achievement, although the findings are not consistent across all the estimated models.

This is a case study of Korea Airports Corporation(KAC) examining the effects of pre- and post-employment experience factors on individual and organizational priority. This study surveyed 240 employees of KAC and analyzed the results. The influence of pre-employment experience (number of times applying to public sector, reason to choose public sector, and job changing experience) and post-employment experience (years of employment, position, and job types) on personal value (authority, achievement, welfare, vacation, and personal life) and organizational value (responsibility, obligation, performance, compensation, and participation) was studied. The results indicated that organizational value is generally greater than personal value. Preference value (=organizational value/personal value) was greater than one for every group. Education, years of employment, position, reason to choose public sector were confirmed to influence preference value. For pre-employment factors, as an employee chooses to work in the public sector because of better balance of work-personal life, preference value was confirmed to be lower. For post-employment factors, when the years of employment are longer and the position is higher, preference value is significantly higher. The results imply that an organization should establish a fair evaluation and compensation system to help employees display their full capability to produce maximum performance.
