In this note, we shall prove a new variational inequality in non-compact sets and as an application, we prove a generalization of the Schauder-Tychonoff fixed point theorem.

We introduce the notion of the generalized covariance and variance for bounded linear operators on Hilbert space, and prove that the generalized covariance-variance inequality holds. It turns out that the inequality is a useful formula in tile study of inequality involving linear operators in Hilbert spaces.

The purpose of this paper is to generalize the Carleson inequality, which is known to play important roles in harmonic analysis. The result given here is a generalization of Coifmann, Meyer, Stein [CMS]. A similar result is shown by Deng [D].

The purposes of this study are to analyze sex education content in high school textbooks and to suggest new guidelines for high school sex education content from a gender equality standpoint. The study analyzes sex-related content from high school textbooks based on the 7th curriculum, including subject areas such as Technical/Home Economics, Sciences, Physical Education, Social Studies and Moral Studies. The analysis relies on the framework of Sexuality Information and Education Council of the United States that covers 4 levels and 6 categories as well as the framework of Choi (2005) that includes 36 themes in 6 different categories. The results of this study are as follows: First, high school sex-related textbooks are focused mainly on human development and human relations. Secondly, there is a lot of level 3 sex education content within the analyzed textbooks. Third, there are gender inequality issues in the coverage of such topics as pregnancy, contraception and sexual violence. Fourth, there are also gender inequality problems caused by content level. This study recommends that gender inequality issues be included in high school sex education guidelines in the future in order to provide improved and appropriate content for high school level sex education.

Purpose: This study was aimed to identify gender-based health inequality and explore impacting factors on health inequality in one province in Korea. Methods: This was an explanatory study using the secondary data on Chungnam province from the Fifth Community Health Survey from August 16 to Oct 31, 2012. Variables included in this analysis were education level, poverty, marital status, and residential community for socio-cultural characteristics and subjective health status as an indicator of health inequality. Data were analyzed by ${\chi}^2$-test, t-test, ANOVA, and multiple linear regression. Results: There were gender inequalities and disparities in health, and these inequalities were greater in woman than in man (${\chi}^2$=161.8, p<.001). The impacting factors were education level, poverty, marital status, and residential community, which was accounted for 22.6% of variances of health inequality. Among these variables, gender showed the largest influence in health inequalities. Conclusion: To solve health inequalities, it should be considered gender differences based on social determinants of health. It is necessary to develop long term project based on these results and the social determinants model of World Health Organization.

This study aims is to explore of the theoretical concepts of regional imbalances and spatial inequality, analysis of spatial distribution of economic growth and identifying of "growth poles" for sustainable development in the regions of Kazakhstan. Based on the theoretical views, we conclude that the key direction of regional policy is the search and development of "growth poles", which will distribute their potential equally to backward regions. The authors propose the methodological tools for presenting a standard form of evaluation of spatial distribution and inequality of the regions of Kazakhstan. This study confirms the importance of using of proposed methods and its application for objectively and realistically defines "growth poles" for sustainable development. Further, the obtained results showed the distribution of Kazakhstan's regions by economic growth and specialization with using modified index of KDI. According to the results of this theoretical and empirical study proved that distribution of the regions of Kazakhstan and results of KDI indexes shows that the spatial differentiation of economic development, but its level and dynamics are different in different respects. In addition, according to the conducted survey, we conclude that one of the most important tasks is sustainable growth based on "growth poles" for sustainable development.

We give an upper bound for the estimation of the difference between both sides of the well-known H$\ddot{o}$lder's inequality. Moreover, an upper bound for the estimation of the difference of the integral form of H$\ddot{o}$lder's inequality is also obtained. The results of this paper are natural generalizations and refinements of those of [2-4].
