Objectives: This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively. For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions: The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

This study investigated elementary students' perception of the suitability of inquiry activities related to the science inquiry, essential features of the inquiry and essential features of the inquiry by science inquiry activities. First, 5-6th grade elementary students' perception of the suitability of inquiry activities to the science inquiry was positive in this study and especially the score of experiment and field trip was high. The lowest score was on the discussion and elementary students thought that discussion might be wrong, because they just talked when they participated in the discussion. Second, perception of the essential features of science inquiry was positive. Especially, engaging students in evaluating their explanations in the light of alternative explanations was the highest. Students thought that explanation is important, but it is too hard to perform the science inquiry with only the explanation. Third, the score of research and experiment was high in essential features of science inquiry by science inquiry activities. The score of the field trip was low, so a more meaningful field trip should be carried out in the school.

The purpose of this study is to analyze the type of latent profile for general high school students' subject selection criteria and to identify the characteristics of the latent class. The survey data of 1072 general high school students (male; 648, female; 424) in G city, Jeollabuk-do and the scale composed of 8 sub-factors: 'SAT orientation', 'academic achievement', 'ability orientation', 'pursuit of interest', 'teacher orientation', 'career development', 'others' recommendation', and 'subject availability' were used for latent profile analysis and cross-analysis between potential layers. As a result of the analysis, high school students' perceptions of subject selection were classified into four latent profiles. The four groups were named 'High Perception Type', 'Low Perception Type', 'Self-Directed Type', and 'Stability-Oriented Type' according to their types. It was found that there was a difference between the latent classes in the importance and performance level of the subject selection criteria. These results can help identify the subject selection tendencies of latent groups in the operation of the 2015 revised curriculum and the 2025 high school credit system that emphasizes the student-centered course selection curriculum and they can also provide customized course selection guidance considering individual differences.

In this study, high school students' perceptions and attitudes toward nanotechnology are examined through questionnaires gathered from 1704 high school students (five general high schools and two science high schools). As a result, the study shows that high school students have generally high perceptions and positive attitudes toward nanotechnology. Science high school students show more positive attitudes and correct knowledge toward nanotechnology rather than general high school students do. High school students get information on nanotechnology via various sources such as TV and internet, whereas they have rarely perceived to get information on nanotechnology in textbooks and science class. They think that newspaper and TV programs are proper methods to introduce new science technology and get information on the advanced science and technology through the internet and science teachers. High school students show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chips and nano-taste enhancer. And they trust nanotechnology researchers and science teachers, whereas they rarely trust about government, public organizations, and internet.
