This study was carried out to identify factors related to breakfasts in elementary, middle and high school students. This study was surveyed by questionnaires and data was analyzed by SPSS program. Exploratory analysis was conducted according to three school student groups (elementary children, middle school students, and high school students). The subjects were 1,886 school students (female 893, male 959) of 51 schools in the nationwide region. The distribution of subjects was elementary school children 544, middle school students 661 and high school students 681. The results are summarized as follows. Only sixty percent of the subjects had breakfast regularly. About one fourth of the subjects had the habit of skipping breakfast or eating it 2$\sim$3 times per week. Frequency of having breakfast and reasions of skipping breakfast were significantly different according to school student groups (p < 0.001 respectively). The rate of skipping breakfast was $14.4\%$ in elementary school, $16.1\%$ in middle school, and $25.0\%$ in high school. The main reason for skipping breakfast was 'not delicious or poor appetite' in elementary school ($42.5\%$), but 'busy' in middle ($50.2\%$) and high school ($61.1\%$). There was no significant difference in frequency of having breakfast according to living areas (rural and urban). There were not significant differences between frequency of having breakfast and BMI and degree of satisfaction on body weight. But there were significant difference in frequency of having breakfast according to economical status (p < 0.05). There were significant differences in degree of school performance according to frequency of having breakfast (p < 0.001) There was significant relationship between the time of attending school and the frequency of having breakfast. But there were significant relationships between frequency of having breakfast and time of rising. These findings suggested that the time of rising was controlled by having enough time that students eat breakfast. And mother (or person who prepares meals) must have more concerns about preparing breakfast for children and students.

Most of the students in middle and high schools today wear school uniforms. The school uniform is the most important and intimate clothes in adolescences and makes students feel a sense of group identity and belonging, and lessen the difference of economical capabilities. However levels of satisfaction is low because school uniforms do not express their individualities and do not keep up with the fashion. In this paper, we studied the partial liberalization of schools uniforms to raise the levels of satisfaction. The subjects were 378 male and female students from middle schools and high school in Ulsan, and a questionnaire was sent out. The survey was conducted in February 2007, and frequency analysis, ${\chi}^2$-analysis, and t-test were used for the analysis of the data. The results are as follows: The students recognized the partial liberalization of the dress code as loosening of the regulation As the result of analysis on attitudes toward the partial liberalization of the dress code, most of the students support the introduction of the plan. They chose a shirt as the most appropriate item and length as the best extent in liberalization. Among the elements of school uniform required to be unified, they selected a jacket and design as the item and extent, respectively. Through this study, we came to know the demands of students for school uniform and confirmed the possibility of the partial liberalization of the dress code as an improvement of consumer-oriented school uniform. In the future, it seems that their desires would be accepted and reflected in the design and school uniforms would be manufactured from the view point of consumer.

The mathematical object is conceptual. Thus we can not prove the property of mathematical object in experimental viewpoint but in conceptual viewpoint. We performed the experiment for 28 middle school students to investigate whether they understand this. As a result, the majority of student didn't cognize the limit of experimental method. We had also individual interviews with four students. As results, one student was exactly cognizing the limit of experimental method, but he couldn't prove logically. The others didn't cognize the limit of experimental method. They thought that the proposition was already true regardless of the error. And one of them even thought that to be equal approximately was the same of to be equal exactly. Also, one student has confused between the experimental viewpoint and the conceptual viewpoint. This implies that it is necessary to help students understand the limit of experimental method.

Many researches proposed different models and concepts for the PCK. It is important to understand its composition. Most studies investigated the development of PCK and its influence on students' learning from the teachers' perspectives. We developed an instrument for assessing middle school students' perceptions of mathematics teachers' PCK (SPOMTPCK) to investigate the nature of PCK. Theoretical claims and empirical research in PCK were used to design questions and sub-scales for the SPOMTPCK. The face validity of the instrument was established by the expert mathematics teachers and students. A questionnaire consisting of 38 items on a five-point Likert-type scale was used for data collection from 799 middle school students. The exploratory factor analyses resulted in the development of a three-factor scale of 17 items that was proved valid and reliable, that is, pedagogical representation, understanding students and curriculum, and encouraging students' engagement. The Cronbach α coefficients of the scale was 0.935, and the Cronbach α coefficient of three factors were ranged from 0.721 to 0.912. The confirmatory factor analysis showed that the questionnaire has good construct validity and the fit indexes are good. MANOVA analysis of variance revealed that the differences in mathematics teachers' PCK identified by students of different school types and grades were statistically significant. It is a validate measurement to evaluate the perceived mathematics teachers' PCK for middle school students.
