For this study, we developed a STEAM program on Air Pollution, which focuses on the control of air pollution and the changes of production processes in Green and Sustainable Chemistry (GSC). This study mainly deals with ascertaining the change in concepts toward air pollution among senior high school students. The STEAM program on Air Pollution includes three worksheets (WS 1, WS 2, and WS 3), and a reference and study history sheet (SH sheet) based on a one-page portfolio assessment (OPPA). The revised version (Korean) of the Air Pollution program was implemented in a senior high school. The results of this study are as follows. The STEAM program on Air Pollution is effective for senior high school students to conduct enthusiastic investigative activity and to develop favorable attitudes towards science and technology. Enabling students to obtain information about historical facts, including their study of scientists, engineers, and the GSC approach, gave them confidence in Science and Technology, and stimulated the development of scientific perspectives and attitudes. © Research India Publications.

An amperometric biosensor modified with a membrane-covered peroxidase and a ferrocene-embedded carbon paste (HRP-Fc-CP) electrode was applied for the highly sensitive analysis of a trace amount of phenols. In this research, various experimental parameters were optimized (content ratio of HRP, pH of solution, temperature of solution, interference, incubation time and temperature, and stability of the electrode). From the results, optimum experimental conditions were as follows: the content ratio of the HRP was 5%, the pH of the solution was 6.5, the temperature of the solution was 35□, and storage temperature was 4□. © Research India Publications.

Generalizing the notions of (ε, ∈ Vq)-fuzzy ideal, (ε, ∈ Vq)-fuzzy quasi-ideal and (ε, ∈ Vq)-fuzzy bi-ideal, the concepts of (ε, ∈ Vqk)-fuzzy ideal, (ε, ∈ Vq k)-fuzzy quasiideal and (ε, ∈ Vqk-fuzzy bi-ideal are defined. Different classes of semigroups are characterized by the properties of these fuzzy ideals. © 2010 Elsevier Ltd. All rights reserved.

The diffuse dielectric anomaly properties of (Pb0.98La0.02)(Zr0.95Ti0.05)O3(PLZT-2/95/5) ceramics were studied by using dielectric spectroscopy methods at temperatures ranging from 20 °C to 650 °C and frequencies between 100 Hz and 106 Hz. It was noted that diffuse dielectric anomaly was observed in the complex dielectric constant at temperatures between 300 °C and 500 °C. We propose a model to explain this phenomena for the diffuse dielectric anomaly. Frequency-dependent characteristic of the dielectric constant at measuring temperature range from 300 °C and 500 °C in the PLZT-2/95/5 ceramic was well satisfied the equation, such as ε (Equation). Finally, the adopted model is satisfactory in rationalizing the diffuse dielectric anomaly at temperatures above the phase transition temperature of PLZT-2/95/5 ceramic.

This study is to investigate the influence of students’ family background factors on the international science achievement using the results of both TIMSS 2003 and 2007. The results of this study are as follows. First, we were able to pinpoint the students’ family background factors that significantly influence students’ science achievement. Among those factors, high rates of book possession and usage of computers at school and at home had a positive effect on science achievement, while high frequency of homework assignments had a negative effect on it. Second, this study demonstrates that students’ science achievement is not only influenced by their educational environment, but also by other factors like their family backgrounds. © Research India Publications.
