The purpose of present study is to examine the science attitude level of middle school, high school and university students, and to provide the suggestions for science education. Instrument to invent science attitude consists of four domains as 'Scientific Inquiry', 'Importance of Contribution to Science', 'Normality of Scientist', and 'Social Value of Science'. Inventory instrument have 20 items(Likert scale of 1 to 5). Subjects are 70 middle school, 72 high school, and 95 university students. There is no significant difference among students by school, but the attitude level toward science of female students is lower than that of male students. 'Importance of Contribution to Science' among four domains has the highest score of attitude toward science, whereas 'Normality of Scientist' has the lowest attitude score toward science. To bring up scientific abilities of students, we conclude that it needs the educational plan to increase science attitude of students, through improving and developing curricular system and science curriculum for the secondary school and university.

This study sets out to assess the scientific literacy of secondary school students and to describe their differences according to gender, grade, course. This study involved 112 middle school students and 213 high school students. Their scientific literacy was measured by the Scientific Literacy Test designed by Manhart (1997). A 70-item multiple-choice test was used to assess their scientific literacy. The constructs of science factor included 36 items making up physical science, life science, and earth science subtests. The social aspects of science factor consisted of 34 items in nature of scientific inquiry/knowledge, science as a human endeavor, science and technology, and societal perspectives. A two-way analysis of variance (ANOVA) and t-test were conducted using the SPSS program. The scientific literacy score of the middle school students was 45.17. There was no significant difference according to gender but boys tended to perform better than girls on both the constructs of science factor and the social aspects of science factor. The scientific literacy score of the high school students was 51.79. There was no significant difference according to gender. But, boys tended to perform better than girls on the constructs of science factor. Girls tended to perform better than boys on the social aspects of science factor. The students taking a course on natural science got statistically higher scores than the students taking a course on humanities. The high school students got statistically higher scores than the middle school students.

This study investigated and analyzed the social and emotional learning components of middle school science, and high school integrated science and science inquiry experiments, which are common subjects that all students must complete. The subjects of analysis were 139 achievement standards of science and curriculum and 496 activities included in textbooks. The research results are as follows. In the case of curriculum achievement standards, 'cultural understanding' was hardly included among the seven science and social-emotional learning elements, 'numeracy' and 'creative thinking' appeared high in middle school, 'critical thinking', 'social technology' and 'ethical understanding' were included with high frequency in high school. And in the case of textbook activity, the tendency of social-emotional learning elements in middle school and high school was similar. 'critical thinking', 'creative thinking', and 'social skills' were mainly provided, while 'ethical understanding' and 'cultural understanding' were reflected in a limited way. In order to cultivate the elements of overall social-emotional learning, it is necessary to specify the achievement standards of the curriculum or to supplement the textbook activities and teaching-learning process.

Dielectric ceramic capacitors present high output power density due to the fast energy charge and discharge nature of dielectric polarization. By forming dense ceramic films with nano-grains through the Aerosol Deposition (AD) process, dielectric ceramic capacitors can have high dielectric breakdown strength, high energy storage density, and leading to high power density. Dielectric capacitors fabricated by AD process are expected to meet the increasing demand in applications that require not only high energy density but also high power output in a short time. This article reviews the recent progress on the dielectric ceramic capacitors with improved energy storage properties through AD process, including energy storage capacitors based on both leadbased and lead-free dielectric ceramics.

The purpose of this study was to investigate the satisfaction with school foodservice programs by foodservice operation type in middle school and high school students in the Geumsan-Gun area. A total of 530 subjects(250 middle school and 280 high school students) from the Geumsan-Gun area participated from March 15 to March 23, 2004. Questionnaires were used to study dietary habits, activity levels, and current health conditions. The results of the study are summarized as follows. Based on the body mass index(BMI) scores of the students, the high school male BMI scores were significantly different(5%), and they were underweight for their height. The students were primarily dissatisfied with times for meals for school foodservice under direct management and with the quantity of meal for school foodservice under contract. Compared to the middle school female students, the male high school students were dissatisfied with the time for meals and quantity of food. Generally, the students were satisfied with dessert items the most. The food most often wasted was soup. The middle and high school students preferred food services to those under contract.

In this study, the meteorology terms in the geography text books of North Korea which includes all of the meteorology educational contents in secondary school curriculum are compared with those in the earth science text books in South Korea. Forty science terms which are the same meaning but composed of different words are picked up to investigate the degree for 89 high school students in Chonnam province to perceive the meanings correctly. High school students' perceptions is on the average 30% higher in terminology of South Korea textbooks than in those of North Korea. But, students' perceptions on 9 North Korean terms is rather higher compared to South Korean terms. Twenty six (83.9%) terms which are difficult for high school students to perceive correct meanings are those lately composed of North Korean native words. Most of meteorology terms in South Korean textbooks are derived from the Chinese characters or imported from foreign language terms are easier for high school students to perceive correct meanings than those of North Korean terms derived from North Korean native language.
