Variable concept plays a crucial role in understanding not only algebra itself but also school mathematics which is algebra-oriented. It solves as an essential means in applying mathematics to the real world because il enables us to describe varying phenomena in the real world. In this study, we examined some matters related to the learning of variable concept in school mathematics. In Particular, we discussed on the teaching of variable concept in the [7-first] stage of the 7th Mathematics Curriculum. We analysed the textbooks in the [7-first] stage and attempted to explain concretely the contents and teaching methods of variable concept which be taught in school mathematics. After reconsidering the practices on variable concept teaching, we pointed out the problems of formalistic teaching method and then proposed the direction in which variable concept teaching should go.

The main purpose of this study was to examine the effects of maternal materialism and parenting on materialism in adolescents. Moreover, the relative significance of maternal materialism and parenting materialism in adolescents was also explored. The study subjects were 199 (98 male, 101 female) high school students in Seoul and their mothers. The following are the major findings. 1) Maternal materialism was not related with male adolescents' materialism but was with female adolescents'. 2) Maternal support, and open communication were negatively related with female adolescents' materialism while maternal control, and permissiveness were positively related. On the other hand, only maternal control was positively related with male adolescents' materialism. 3) Stepwise regression analysis revealed that maternal support, followed by maternal materialism, was the most important variable affecting female adolescents'. However, for male adolescents, maternal control was the only one variable affecting their materialism.

The concern over beauty is increasing as the importance of appearance is becoming more prominent. Accordingly, the importance of studying beauty is now apparent. The purpose of this study is to analyze existing beauty-related research in order to assess current trends in beauty-related studies. Materials were collected from the master's theses and academic journals from 1997 through 2016. In addition, 81 beauty-related papers were selected and classified into 3 categories according to their subjects and content. There were 19 hair attitude papers, 52 papers about make-up and skincare, and 10 papers on cosmetic surgery. Each type was divided into detailed themes according to the study theme and its number was grasped. Consequently it was classified into 9 themes about the attitude toward hair and the relevant variable study, 10 themes about the attitude toward hair style and relevant variable study, 24 themes about the make-up attitude and relevant variable study, 28 themes about the skin care attitude and relevant variable study, and 10 themes about the cosmetic surgery attitude and relevant variable study. The results revealed that academic concern about beauty sharply increased starting in 2005. Moreover, we determined that the methodologies used in hair and make-up studies were sound and detailed, while cosmetic surgery studies were more inconsistent and poorly analyzed. Thus cosmetic surgery should be further researched in a more standardized and thorough manner. This review of attitudes toward beauty will serve as a basis for follow-up studies that employ meta-analyses to draw more quantitative conclusions by aggregating many more study results.

With the advent of lean-six sigma era, an extensive use of analytic tools such as control charts is required in the field of manufacturing. In relation to statistical quality control (SQC) or process control (SPC), the Korean standards have undergone a meaningful change. In this study, the theoretic backgrounds for evaluating the control limits in connection with the variable control charts are examined in view of better understanding the related constants and coefficients. This paper is intended to help the quality control practitioners understand the mathematical backgrounds by comparing related quality control constants and also to encourage them to make use of and to take the advantage of the variable control charts which are very useful for implementing the concept of lean-six sigma in many industrial sites.
