From September 1, 2003 to November 30, 2004, 20 mineral water wells were selected for some area in east Europe and the study on their water quality was analized. It revealed that mineral water contained considerable quantity of magnesium ions which helps the smooth activities of vascular muscles, nervous systems and protects skins from allergic reactions. It also lowers cholesterol level and contains high concentration of calcium ions which is one of the vital components of teeth and bone like phosphorus. Thus it is concluded that it is not qualified as boiler feed water as it has overall high degree of hardness by the presence of four times content of $Mg^{2+}\;and\;Ca^{2+}$.

The purpose of this study was to investigate the effects of interview with a scientist and engineer on service performance assessment on science career orientation and image of scientists. Science track students in the 11th grade carried out the interviews and made powerpoint presentations. After the students' presentation in the chemistry class, the teacher made comments on the contents of the interviews. Students gave presentation in each class for a year. Before starting this assessment, students took science career orientation questionnaire and DAST (draw-a-scientist-test). These two tests were conducted again at the end of the year. The results of this study showed that there was no significant difference between pre- and post-test score for the science career orientation. However, a significant difference was observed in the 'preference for science learning' category. These results showed that the career decision of a high school student has already been fixed rigidly. On the other hand, there was a significant difference (p < 0.01) between pre- and post-test on the image of scientists. This demonstrated that the stereotypic image for a scientist was reduced by the interview performance assessment and that, students came to have an affirmative perception of scientists on service.

This study analyzes the depictions of scientists and teachers' thoughts on the 2015 revised elementary school science authorized 3rd-4th grade textbooks from the perspective of gender equality, and suggest improvements for the 2015 elementary school science authorized 5th-6th grade textbooks as well as a 2022 revised elementary school science curriculum. The data consist of representations of scientists found in seven elementary science textbooks provided to 3rd- and 4th-grade students in 2022 as well as in-depth interviews conducted with three elementary school teachers and responses from 32 teachers in Gyeonggi-do. Of the 23 scientists depicted in the textbooks, three (13.0%) are female and 10 (43.5%) worked in the inquiry domain, which was the largest group. When the teachers were asked about their perceptions of the gender ratio of scientists in the textbooks, their answers revealed that they had lower perceptions of female scientists compared to male scientists; moreover, they had no or very little teaching experience concerning female scientists. Furthermore, the teachers' thoughts on improving the gender ratio of scientists depicted in the textbooks differed considerably by the teachers' gender. Based on these findings, it was concluded that during the process of producing textbooks, writers and members of society need to agree on the gender ratio of scientists to be represented, and a social consensus is needed to identify and introduce the achievements of previously unknown female scientists towards gender equality.
