The dependency of long-range order parameter on the ordered structure of $Pb(Mg_{1/3}Nb_{2/3})O_3$ solid solutions has been investigated by means of computer simulations of high-resolution lattice images. The computer image simulations were performed by the multislice method in a wide range of sample thicknesses, defocusing values, and long-range order parameters. It was found that the lattice images of the ordered structures were predominantly dependent on the long-range order parameter, The lattice images in a complete ordered structure showed a pseudo-hexagonal pattern. As the order parameter decreases, the simulated images changed slowly from a pseudo-hexagonal pattern to a rectangular pattern. The lattice images in a complete disordered structure showed a rectangular pattern. Also, the simulated images of the $Pb(Mg_xNb_{1-x})O_3$ with different Mg:Nb ratios obtained at a given long-range order parameter were basically the same patterns, irrespective of Mg and Nb compositions.

This study analyzed the contents of the milk-related nutrition education currently found in elementary and secondary school textbooks. An attempt was made to develop the basic data needed to in the future provide students with pertinent in formation regarding the nutritional attributes of milk, as well as the desired consumption behavior, within the school education system. To attain the objectives of this study, the researcher analyzed the contents of the milk-related nutrition education described in elementary and secondary school textbooks(1st-10th grades). Based on the results of this analysis, measures were developed to organize the contents of the milk-related nutrition education that should be taught within the school education system. At the elementary school level, milk-related nutrition education was included in the textbooks for the integrated curriculum for the lower grades, as well as in the science, practical arts, and physical education textbooks for every grade, except the End and the 6th. The practical arts textbook, which contained basic knowledge related to the nutritional attributes of milk and the proper method in which to intake milk, was found to be the one which dealt with milk-related nutrition education in the most detail. At the secondary school level. milk-related nutrition education was included in the 7th-10th grade textbooks for the science, technology and home economics, and physical education courses. In this instance. the technology and home economics textbooks were the ones which were found to contain the most milk-related nutrition education covering such aspects as the nutritional attributes of milk, the special characteristics of milk as a food. how to select and store milk. as well as how to use milk as part of a balanced diet in everyday life. However, as was the case at the elementary school levet the repetitious nature of the milk-related contents found in the textbooks for various school subjects and at different school levels, as well as the inefficient hierarchical structure in which the knowledge is presented, were identified as key problems. There is a need to establish the appropriate milk-related nutrition education for each school level. The need to develop education programs, which could be linked to the school subjects and special milk programs, was also emphasized.

This study attempts to identify the relationship between students' images of science and science learning, and their career choices. A total of 163 students (seventh graders) from three different middle schools participated in this study. Students' images of science and science learning were investigated using the Draw-A-Scientist Test (DAST) and the Draw-A-Science-Learner Test (DASLT), respectively. Then, students' drawings were analyzed using the Draw-A-Scientist Test Checklist (DAST-C) and the Draw-A-Science-Learner Test Checklist (DASLT-C). The relationship between each element composing the students' images and their career choices were analyzed. Among several elements constituting the students' image of science, 'expression,' 'lab coat,' 'oddity,' 'knowledge symbol,' 'technology symbol,' 'co-work,' 'danger,' and 'STS' showed significant differences between students who chose a science-related career and students who did not. It was also revealed that the following elements - 'expression,' 'learning type,' 'inquiry symbol,' and 'learning place' - were more significantly associated with a science-related career choice compared to other elements consisting of an image of science learning.

The purpose of this study was to develop health belief model based various milk education program as print education media and apply to elementary, middle, and high schools. The subjects were 432 students(124 elementary, 122 middle, 186 high school students). We designed one group pretest-posttest study model. The data were obtained from pre and post-study with self-administered questionnaires. Before applying this education program, we evaluated the degree of awareness on milk. Their awareness on milk was very low, 35.5% lower elementary, 32.7% higher elementary, 52.5% middle, and 54.3% high school students were answered they don't know the milk well. After they had implemented milk education program, their recognition on milk had changed that milk is nutritious as supplementary food. And their reasons for drinking milk were also changed that 'they want to eat it' in elementary school students, 'they want to be healthier' in middle school students, and 'they want to be taller' in high school students. Their nutrition knowledge score showed a significant increase(p<0.05). As a results. milk nutrition education has improved nutrition knowledge and recognition on milk in elementary, middle, and high school students. To improve their milk eating behaviors, nutrition education programs will have to be continued.
