In this study, we investigated elementary school teachers' and students' perceptions of the reading materials in science textbooks. Participants were 181 teachers from 23 elementary schools who were teaching science and 643 third- to sixth-grade students from 12 elementary schools. A questionnaire for teachers consisted of 18 items and a questionnaire for students consisted of 11 items about their perceptions of the reading materials in science textbooks. Nine to twelve items, according to grades, examining the actual uses of each reading material in science textbooks were also included to both questionnaires. The results indicated that teachers have positive perceptions about reading materials and frequently use them in case of needs for supplement and/or enrichment of science learning. Novice teachers were found to have less positive perceptions about reading materials than expert teachers. Over 70 percent of students responded that they read all reading materials. Fifth- and sixth-grade students were tended to have less positive perceptions about reading materials than third-grade students. Finally, students tended to have more positive perceptions about reading materials than their teachers.

This study aims to clarify the difference between scores for time management practice and the self-evaluation of time use according to time rules in families. This study used data obtained from the first survey on after-school activities in 2008, conducted by the Benesse Educational Research and Development Institute in Japan. The study sample consists of 3,372 middle school students. First, scores for independence and planning were highest in third grade, yet the score for regularity was also lowest in third grade. There will be different lifestyles even among middle school students of the same grade, so it is necessary to consider their characteristics and family rules. Second, the scores for independence, regularity and planning were lowest in groups whose families had rules about time (time rules for curfew, time rules for watching television, time rules for playing games), but in which those rules were not kept. These results were similar for both boys and girls and show that it is more important keep rules rather than to make rules.

This study examined the current interior conditions of children's rooms, and investigated the children's satisfaction of the rooms and their needs for improvement. Survey questionnaires were given to 205 elementary school children in the third or lower year grades and to their parents. Frequency analysis, t-tests, analysis of variance, and Duncan tests were mainly employed for data analysis. The findings indicated that the respondents' satisfaction of the children's rooms differed in their grade, room size, and the main color of the rooms. In general, those in the third grade, those in the rooms under 16.5$m^2$, or mainly painted in cold colors, tended to respond more negatively. Meanwhile, they expected to exchange their furniture for study, such as desks and bookshelves, and to individually possess electric appliances in their rooms. Most children's rooms were designed on the basis of the parents' preferences: The more the rooms reflected the children's opinions, the higher satisfaction with the furniture they showed.

The purposes of the present study were to give the new direction of teaching English based on the 7th English curriculum, and to show some useful insights on English teaching in the 21st century. The 7th English curriculum was developed in two parts: as a required subject and as an elective subject. As a required subject, the English curriculum applies to the third grade of elementary school through to the first grade of high school. The elective subject of the English curriculum applies to the second and third grades of high school. In the 7th curriculum reform, a proficiency-based language program will be applied in the form of intensive and supplementary courses at the same levels irrespective of differences based on students' abilities, schools and regions. Linguistic functions, communicative functions, subject matters are included in the content area in language organization. Limiting the length of sentences is applied at elementary school only and is not applied at higher levels.

Chordoid glioma is a rare primary brain tumor of the third ventricle, and was recently characterized as a novel tumor entity. Typical radiological features of chordoid gliomas include; a solid, round-to-ovoid, well-circumscribed, contrast-enhancing mass of the hypothalamus and anterior third ventricle. Despite being classified as WHO grade 2, the third ventricular chordoid glioma has been reported to have a poor clinical outcome because of its anatomical location. The authors report a case of chordoid glioma of the third ventricle in a 48-year-old man with unusual radiological features of cystic component and ill defined circumscription.

Objective : This study is designed to present the direction and the necessity of education on the biomedical ethics the establish desirable ethical view of paramedic students by understanding on the consciousness of students of department of emergency medical technology on biomedical ethics on euthanasia. Method : Data were collected from on 335 students of department of emergency medical technology in 4-year-college located in districts of Chungcheong-do, from March 4 to April 22, 2010. The questionnaire consisted of total 29 items, i.e., 11 items of general characteristics, 11 items of characteristics related to biomedical ethics and 7 items of consciousness on euthanasia. Result : In general characteristics, the first grade showed the most dense distribution of 37.3%, the second grade was 20.0%, the third grade was 20.9% and the fourth grade was 21.8%. In the consciousness of biomedical ethics on euthanasia, the third and the fourth grades showed a higher ratio(${\chi}^2$ = 136.327, p= .000), in comparison with the first and the second grades, the higher year they were, the higher degree of consciousness they had. The consciousness on each item of euthanasia showed significant differences in grade (F = 8.203, p= .000), experience of clinical practice or none (t = 3.731, p= .000), experience of biomedical ethics education or none (t = 1.997, p = .047) and degree of consciousness on DNR (F = 8.240, p = .000) regarding 'CPR shall not be required in any cases if a patient wants DNR', in experience of biomedical ethics education or none (t = 2.452, p= .015) and degree of consciousness on DNR (F = 2.725, p = .044) regarding if a patient refuses all treatments, the patient's opinion shall be respected', and in degree of consciousness on DNR (F = 2.858, p = . 037) regarding 'after determination of DNR, if the family wants a positive treatment, it shall follow the family's request'. Conclusion : It seemed that the differences in consciousness according to grade and experience of clinical practice were influenced by experiences to treat patients in personally. Moreover, it showed that the higher grade they are, the more experience of education they have, the experiences of education had influences on the consciousness. Development of educational programs is required in order to supply accurate knowledge on biomedical ethics for euthanasia to lower-grade students the to let them establish ethical views properly, and in order to correct wrong knowledge and to establish ethical views while supplying knowledge on biomedical ethics for euthanasia to higher-grade students.
