  • The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.

  • In pH 4.2 HAc-NaAc buffer solution, horseradish peroxidase (HRP) catalyzed $H_2O_2$ oxidation of nanosilver to form $Ag^+$. After centrifugation, $Ag^+$ in the supernatant can be measured by graphite furnace atomic absorption spectrophotometry (GFAAS) at the silver absorption wavelength of 328.1 nm. When HRP concentration increased, the $Ag^+$ concentration in the supernatant increased, and the absorption value enhanced. The HRP concentration in the range of 0.84-50 $ng{\cdot}mL^{-1}$ was linear to the enhanced absorption value (${\Delta}A$), with a regression equation of ${\Delta}A$=0.012C+0.11, correlation coefficient of 0.9988, and detection limit of 0.41 $ng{\cdot}mL^{-1}$ HRP. The proposed GFAAS method was used to detect HRP in waste water samples, with satisfactory results.

  • As a comprehensive study on the development of curriculum for environmental education based on the standpoint of ecology, the environmental issues within the science textbooks used in the elementary, middle and high school were analyzed with the special emphasis to four aspects; 1) the causes and 2) the examples of environmental pollution, 3) the principles of ecology, and 4) the endeavor to overcome environmental crises. The results confirm that the science textbooks were written on the basis of Environmentalism rather than Ecology, and the environmental issues were listed fragmentarily within the subjects related to science, and not systematically assembled between inter-subjects or-sciences. Therefore, the systematic and inter-scientific approaches based on the ecology will be needed for further and better environmental education.

  • This paper is about interactional characteristics of a middle school student's conceptual ecology in the context of conceptual change. A case study in this paper shows that: (1) there is interacted with three characteristics(conceptions, past experience, and explanatory coherence) within conceptual ecology; (2) the interactional characteristics of conceptual ecology have significant affects on the difficulties of conceptual change. Implications of this case study are that: (1) teaching for conceptual change should start at the certain site related to subject-matter task within students' conceptual ecology; (2) Students' inconsistent explanations could be used as the clue of conceptual change; (3) Past experience is the important area of conceptual ecology research for understanding learners.

  • This study investigated unmarried college students' knowledge of sex and cognition of prenatal education. It also aimed to provide insights into how college students' awareness of prenatal education may be raised and to make future married couples practice prenatal education. This study used a descriptive correlational research design. Participants were 346 college students in North and South Jeolla Province. Descriptive statistics with the SPSS WIN 12.0 program were used to analyze the collected data. Important findings were as follows: The mean knowledge of sex was .55, which was near moderate level. The mean cognition of prenatal education was 4.08, which was near high level. Knowledge of sex was influenced significantly by sex and major, whereas cognition of prenatal education was influenced significantly by sex. Thus, it was found that when considering how to raise the cognition of prenatal education and sexual knowledge of sex, both gender and major are important factors to consider.
