  • Shear keys in precast concrete segmental bridges (PCSBs) are usually match-casting which is very labour intensive. In this research, an innovative match-casting-free construction was proposed by leaving small gap between the convex and the concave castellated shear keys in the joints of PCSBs. Specimen experiment, shear strength analysis and numerical simulation were conducted, investigating the loading performance of this new type of dry joints, the gap dry joints. Compared with match-casting joint specimens, it has been found from experiment that shear capacity of gap joint specimens significantly decreased ranging from 17.75% to 42.43% due to only partially constrained and contacted in case of gap dry joints. Through numerical simulation, the effects of bottom contacting location, the heights of the gap and the shear key base were analyzed to investigate strength reduction and methods to enhance shear capacity of gap joint specimens. Numerical results proved that shear capacity of gap dry joints under full contact condition was higher than that under partial contact. In addition, left contact destroyed the integrity of shear keys, resulting in significant strength reduction. Larger shear key base remarkably increased shear capacity of the gap joint. Experimental tests indicated that AASHTO provision underestimated shear capacity of the match-casting dry joint specimens, while the numerical results for the gap dry joint showed that AASHTO provision underestimated shear capacity of full contact specimens, but overestimated that of left contact specimens.

  • The purpose of this study is to analyze the difference of economic condition of students, that is, the difference of basic information utilization ability stemming from education gap. First, we investigated information literacy for high school freshmen who can control the difference of information utilization education experience by school. In doing the research, 629 high school students in the metropolitan city were surveyed using web. we analyzed the educational gap between schools depending on their economic conditions and analyzed the correlation between education gap and basic information utilization ability. As a result, it was found that there is a very significant negative correlation between the ratio of students who get support for school expenses and basic information utilization ability. Second, regression equation was produced through regression analysis of information literacy regression to analyze the effect of educational gap on basic information literacy. In addition, it seeks to consider alternatives that can improve the inequality of information literacy which is derived from education gap.

  • Recently in South Korea, various methods are followed in decreasing educational gap between region and social classes through school education. The National Assessment Educational Achievement(NAEA) intends to strengthen responsibility of school education and manage quality of curriculum. Besides, the NAEA intends to bridge achievement gap which is one of educational gaps by grasping the characteristics of academic ability to guarantee basic academic ability. There is not much research about the educational gap among regional scales. Therefore in this study, to examine the achievement characteristics among regional scales closely, we analyse the 2010, 2011 NAEA results in elementary mathematics subject and explore characteristics of items which have sharp differences between local population sizes. The results of the analysis has been showed that the educational gap between 'big-sized cities' and 'small and midium-sized cities' has been increased, but the overall educational gap among regional scales has been decreased.

  • This study starts from a question about the expectation that government policy reduces the educational gap by introducing digital textbooks. In addition, we try to figure out how to minimize the problems that will occur when digital textbooks are introduced and fully adopted. The purpose of this study is exploring the possibility that suing digital textbook deepens learning gap among students. Researchers are discussed that the gap between 'information' haves' and 'information' have-nots' and between 'the competent user' and 'the incompetent user' increase difference between 'knows' and 'know-nots' on the socio-economic class. These difference are likely to imply that using digital textbook is deepening the educational gap.

  • Colleges of technology in Japan are characterized by specialized education starting from the first grades aged fifteen, making it particularly important to provide motivation for specialized subjects. The most difficult thing for teachers in the technical college is giving the motivation to a professional education to the lower grades who don't know the technology and engineering. Teachers tried to use and make a suitable example or an education material for their lecture. The generation gap with students makes it difficult for teachers to use examples of objects that students are actually familiar with in their daily life. To compensate for the generation gap with students, we asserted that education for lower grades should adopt the perspectives of students in higher grades. The relative closeness in age of lower and higher grades helps reduce the generation gap with students, which is advantageous in that teachers can share the perspectives of students.

  • This study aims is to analyze of existing concepts of gender stereotypes and gender differences in wages, defining of gender pay gap determinants, and to evaluate the level of discrimination against women in Kazakhstan. This paper begins by reviewing trends in gender stereotypes and gender segregation during the past several decades. In this research, authors propose the methodological tools for presenting a standard form of evaluation of gender pay gap. The developed methodological tools will allow providing authentic and formal analysis on gender pay gap and identifying the main determinants of gender pay differences. Further, the obtained results showed the distribution of wage gap in Kazakhstan's regions and the Duncan's dissimilation index allows us to trace the dynamics of changes in the professional structure between men and women. According to the results, gender pay gap is narrowing with the reduction of the job level and discrimination is related to differences in human capital and education. Wages in the industrial sector are higher for men than for women, because men's professions are characterized by severe and unhealthy working conditions. In addition, employers prefer male managers, but if they take woman managers, they give them salary 3 times less.

  • In this article, we considered a class of nonlinear variational hemivariational inequality problems and investigated a gap function and regularized gap function for the problems. We discussed the global error bounds for such inequalities in terms of gap function and regularized gap functions by utilizing the Clarke generalized gradient, relaxed monotonicity, and relaxed Lipschitz continuous mappings. Finally, as applications, we addressed an application to non-stationary non-smooth semi-permeability problems.
