The purpose of this study was to investigate the current status of health promotion policies about antismoking, and the relationship between policy status, enforcement of smoking restrictions and perceptions of smoking behaviour among teachers. A representative sample of 173 teachers$.$school inspectors from 150 elementary$.$middle$.$high schools in Gangwon-do was surveyed during Gangwon-do Office of Education's antismoking and temperance training course in 2002 (response rate 60.7%). One staff member from each school was also analyzed regarding school antismoking polices for students and teachers in several locations within and outside the school building. The results showed that 118 elementary$.$middle$.$high schools (78.7%) had an antismoking policy and more schools had a written policy on student antismoking than on teacher antismoking. Most schools (92.4%) in the sample banned smoking by students, but 52 schools (44.1%) allowed smoking by teachers in restricted areas. However, teachers reported seeing smoking sometimes in the toilets (42.7%) or the playground (40.0%) among students and sometimes in the staff room (31.3%) or about every day on school premises (52.7%) among teachers. Irrespective of the type of policy or restrictions on smoking, the association between having a ban on student/teacher smoking and teachers' perceptions of student/teacher smoking in school was not significant. In conclusion, we suggest that most schools must have explicitly an antismoking policy on both students & teachers and enforce consistently a ban in promoting a healthy school environment(smoke-free schools).

This paper aims at the examination on the fallacy of the name of 'Dadaepo-gaeksa'. The results are as follow: The so called 'Dadaepo-gaeksa' was one of the official buildings of Dadaejin, the naval forces in the late period of J osun dynasty. The building was moved to Molundae near the original site in 1970. And two years later, it was designated as a cultural asset. However it's real name is 'Dadaejin-dongheon', because Dadae-jin gaeksa was demolished about the time of the foundation of Dadaepo-elementary school. Otherwise, Dadae-jin donheon was used as a school building from 1904 to 1970. Futhermore, the architectural style of the existing building is different from the general gaeksa's in the period of J osun dynasty. Therefore, the name of Dadaepo-gaeksa needs to change into Dadaejin-gaeksa and to restore as its original style.

Objectives: This study is to examine the polyvinyl chloride (PVC) materials in elementary school classrooms and libraries in Seoul, and to investigate phthalate contamination in indoor dust. Methods: PVC material was identified for building materials and furniture using portable x-ray fluorescence (XRF). Phthalates in dust samples (n=19) were extracted by ultrasonic extraction using cyclohexane and analyzed by GC-MS. Results: Diethyl phthalate (DEP), di-n-butyl phthalate (DBP), and Bis (2-ethylhexyl) phthalate (DEHP) were found in all collected dust samples (n=19), and diisonyl phthalate (DINP) was detected in all except for one sample (n=18). The concentration of DEHP (median: 2190 mg/kg) and DINP (2960 mg/kg) were higher than other compounds, suggesting that there are many products in the school that used these compounds. When comparing the phthalate concentration in the classroom (n=11) and library dust (n=8), the total concentration in the classroom (median: 10000 mg/kg) was higher than that in the library (8030 mg/kg). DEHP was the dominant compound in the library. The library is relatively more equipped with PVC furniture (n=83) and most floors are also identified as PVC material, suggesting that floors and furniture made of PVC materials are main sources of DEHP contamination. Conclusions: This study is a pilot survey for investigating phthalate contamination in elementary schools. As a result of the survey, phthalate contamination in elementary school was confirmed. However, further study requires risk assessment of children through analysis of phthalate metabolites in children based on sufficient number of samples and information about the site.

신축 녹색건축물의 환경영향 감축 효과를 평가하기 위해서는 비교를 위한 기존 건축물에 대한 환경영향 결과가 필요하다. 본 연구는 비교 기준을 제시하기 위하여, 많은 기존 건축물에 대한 환경영향을 사례 분석하는 것을 목적으로 한다. 이를 위하여, 산업연관표와 에너지원별 목록분석 데이터(LCI)를 기반으로 하는 LCA 모델을 이용하여 서울, 부산, 대구, 광주 지역의 17개 초등학교 건축물에 대한 환경영향(지구온난화지수, 오존층파괴지수, 산성화지수, 부영양화지수, 광화학산화지수, 자원고갈지수)을 평가하였다. 평가 결과, 초등학교 건축물의 환경영향은 연면적, 사용에너지원의 차이에 따라서는 큰 차이를 보이지 않은 반면, 지역에 따라 명확하게 구분되는 것으로 나타났다. 이에 따라, 본 연구에서는 지역에 따라 구분된 비교 기준을 제시하였다. 예를 들어, 서울, 부산, 대구, 광주 지역에서의 GWP에 대한 비교 기준은 각각 3.76E+03, 1.90E+03, 2.63E+03, $2.81E+03kg-CO_2\;eq./m^2$로 나타났다. 제시된 결과는 신축 녹색 초등학교 건축물의 환경영향 저감 효과를 파악하는데 활용될 수 있을 것으로 기대된다.

In social constructivist teaching, knowledge construction is achieved through learners' collective social interaction. Vygotsky argued that this process is mediated with language use, and the development of higher order thinking is realized through the transition from inter-personal psychological functions to intra-personal psychological functions. In so doing scientific concepts are internalized to learners. This study examined the third grade elementary students' inter/intra-personal psychological functions and their internalization processes during social constructivist teaching plan about strata and fossils. The lessons were designed along with Wells' dialogic inquiry and Leach and Scott's social constructivist teaching-learning sequences. Results showed that a teacher's utterances of talking with questioning to switch attention, creating cognitive disequilibrium, and expanding the width of students' opinions could make effective inter-personal psychological function. In addition, a learner's inner speech expressed into social discourse through talking about personal experiences, comparing epistemic idea with visual representation, or applying to different situation showed his/her intra-personal psychological function. Some cases of learners' internalization through language use could be at the stage of knowledge building and understanding of the spiral of knowing, but not all. Thus it is argued that a teacher's deeper insight into Vygotskian social constructivist teaching can make elementary science classroom teaching more effective in their inter/intra-psychological functions.

The purpose of this study was closely to explore the guidance experiences of senior elementary teachers who have had over 30 years of teaching experiences in elementary school based on interpretive(or hermeneutic) inquiry. The entry research question was 'What are the guidance experiences of senior elementary teachers like?' Seven senior elementary teachers working for O elementary School in G city participated in this study voluntarily. Each participant was interviewed twice in a consecutive manner. 14 periods of interview were completed all together and each period took about 40-60 minutes. In conclusion, this study conceptualized the guidance experiences of the senior elementary teachers(participants) as follows: First, the concepts of guidance held by the participants were conceptualized as 1) supporting and caring activity helping students to lead joyful school life, 2) assisting activity helping students to grow on good basic life habits, 3) character building activity helping students to lead integrative growth. Second, the fields and contents of guidance held by the participants were conceptualized as basic life habits, manners, and health & safety. Interestingly, these concepts were evolved in connection with their personal, practical teaching experiences rather than in-service teacher education. Third, the guidance methods frequently used by the participants were co-work with parents, exemplary storytelling, counselling, and praise. The participants applied these methods differently according to the grade, individual difference, and school curriculum policy to some degree. Fourth, the participants have experienced a lot of struggles with students, teachers, and parents in doing their guidance practices throughout the whole teaching career. Their guidance experiences commonly shifted from more teacher-centered or authoritative to more student-centered or relational way as their teaching years accumulated. Interestingly, all the participants more or less lived as lifelong learners to create their own right space as senior teachers in today's competitive and challenging landscape. This study strongly suggests that responsible teacher education can playa great role of enabling senior teachers to cope with guidance issues successfully. Compared with the speedy social change, the teacher education in Korea had been so authoritative, provider-based, subject-based until recently and it have not met the needs and wants of the elementary teachers in field. This trend has significantly hindered them from catching up with the needs of the speedy social change in terms of contemporary guidance issues. This study is limited in that the data is solely collected based on interview. So, an observational research is strongly suggested in order to uncover the situated understanding of the guidance experiences of elementary senior teachers.
