  • Purpose: The purpose of this study was to investigate the concentrations of volatile organic compounds at elementary, middle, and high schools in Ulsan and its surroundings. Methods: To assess the hazardous chemicals of the 66 classrooms in the 22 schools, the 6 volatile organic compounds such as TVOCs (Total Volatile Organic Compounds), benzene, toluene, xylene, ethyl benzene and stylene were measured and analyzed from the beginning of May to the end of December, 2009. Results: The mean concentrations of TVOCs in the elementary schools were higher than those of middle and high schools, and multi-purpose classrooms was higher than that in general ones. The benzene and toluene level in schools in Dong-Gu in the vicinity of assorted industrial complexes was higher than that of schools located in other districts around the Ulsan Metropolitan Area. Conclusion: In case of schools in Ulsan Metropolitan Area, elementary school, schools in Dong-Gu, and multipurpose classrooms over general classrooms should be given a high priority for the management of volatile organic compounds.

  • This study was conducted to evaluate the effects of volatile organic compounds and formaldehyde of newly-built school classroom indoor air on the neurobehavioral functions of students. The elementary schools that were opened in September 2008(as of September 2008) was selected for newly-built school and the elementary school that were opened in March 2006 was selected for control group schools. The concentration of formaldehyde(HCHO), a hazardous organic compound that exists in the air of classrooms, exceeded the standard value of $108.2{\mu}g/m^3$ in newly-built schools while it was $60.8{\mu}g/m^3$ in control group schools, which is around 60% of the standard concentration. However, the concentration of the total volatile organic compounds(TVOCs) was $788.9{\mu}g/m^3$ and $756.1{\mu}g/m^3$ in newly-built schools and control group schools respectively, which are approximately two times higher than the standard concentration. In newly-built schools, the mean reaction time of additions and symbol digit, respectively 3,020ms and 2,398ms in pre-exposure were increased to 3,167ms and 2,514ms respectively in post-exposure. The difference of mean reaction time between pre and post exposure was 146.8 ms, or 4.6%, and 116.7ms, or 4.8%, respectively, showing statistically-significant increase of reaction time(p<0.05). On the contrary, the difference of reaction time of both tests were not statistically significant in the control group schools. These results showed that the neurobehavioral performance of newly-built schools students were affected by volatile organic compounds and formaldehyde of classroom indoor air.

  • The idea of the school networks for joint venture and use of school facilities is forming and using an organic network of schools that will communally share a group of facilities that are uniquely appropriate for each schools. Focused on two prominent cities of Northern Choongnam province, Cheonan and Asan city, the objective of this study is to present and exhibit the plans for joint venture and use of school facilities, and to use them as an example for other provincial cities within the nation where such renovation may be possible. The school networks is proposed based on units of 1 km radius around each site, that is named as small school network, in order to ease the communal use of the sidewalks by the residents and the facilities by the nearby schools. In Cheonan city, six small school networks were proposed, which will supply three to four elementary schools for an average of 50,000 people. On the other hand, Asan city, which showed shortages of elementary schools, three small school networks including the middle and high schools in addition to the elementary schools were proposed, that will provide three to six schools for an average of 30,000 people.

  • The purpose of this study was to investigate dietitians or nutrition teachers' perception of sugar reduction and usage of sugars in school meal service. A survey was conducted for dietitians or nutrition teachers at elementary, middle, and high schools in Gyeonggi and Incheon. Survey data were analyzed according to the experience period and school types of dietitians or nutrition teachers. The numbers of subjects according to work experience period were 134 (44.2%) for <5 years, 68 (22.4%) for ${\geq}5$ and <10 years, and 101 (33.3%) for ${\geq}10years$. Among the subjects, 168 (55.4%) were nutrition teachers at kindergarten/elementary schools, and 135 (44.6%) were at middle/high/special schools. Perceptions of sugar reduction programs were higher in kindergarten/elementary schools than in middle/high/special schools. The perception of added sugar use increased with more work experience, and interest in sugar reduction was higher in kindergarten/elementary schools than in middle/high/special schools. Practice for added sugar reduction increased with more work experience, and the most common method for reducing sugar was use of natural sugars. The main reason for not reducing added sugars in school meals was due to preference. Nutritional education for students increased with more work experience and was higher in kindergarten/elementary schools than in middle/high/special schools. The major nutritional education methods were using school homepage (37.4%), sending family letters (37.4%), and using principle's discretion time (18.4%). Organic sugar and rice taffy were used more at kindergarten/elementary schools, and white sugar, brown sugar, and white syrup were used more at middle/high/special schools. The most common menu using added sugars was stir-fried dishes (stir-fried pork, chicken, and vegetables).

  • Purpose: The purpose of this review is to introduce the progress of health promoting schools in Korea and future tasks. Method: From 2009 to 2018, we reviewed the literature on health promotion schools in Korea conducted by the Ministry of Education Results: Over the past decade, Korean health promoting schools have operated from a minimum of 14 schools to a maximum of 98 schools each year. As a result of the effectiveness evaluation, it was found that the students had a positive influence not only on the health behavior but also on the whole school life. Under the organic cooperation of the Ministry of Education, the Office of Education, the Korean Educational Development Institute and the schools, consulting, provision of educational opportunities for teachers, promotion of good practices, and public relations support systems for generalization are well established. Conclusion: Promotion and support system for Korean health promoting schools are already well established. Nevertheless, there are limitations on the universalization of health promoting schools, so various attempts such as introduction of certification system should be continued to overcome them.

  • Recently, indoor air quality (IAQ) in workplace, residential environments and schools has been concerned of people, scientists and related the public, and has recognized the healthy effectsrelated to IAQ, specially in schools in Korea. Therefore, objectives of this study in this study were to measure and compare the perception of TAQ of selected air pollutants in Seoul from April to September 2004. Measurement place measured 2 schools of Seoul and local 9 schools (by Kyonggi Province, Chungchong-bukdo Chungchong-namdo, Chollado-bukdo, Cholla-namdo, Kyongsang-bukdo, Kyongsang-namdo, Kwangju, schoolin Pusan each 1 place). Temperature, humidity, illumination, carbon monoxide, carbon dioxide, TBC (total bacteria count), noise, PM10, TVOC(total volatile organic compounds), HCHO (formaldehyde) were measured simultaneously. Also, we Performed a questionnaire survey of 250 students and 50 teachers about their awareness for the importance of IAQ in their schools. Among this article, we handled noise, carbon monoxide, carbon dioxide, TBC, TVOC, HCHO, PM 10 in our conclusion. Major results were as follows ; Carbon monoxide (CO) was lower than indoor air standard of Korea. Carbon dioxide $(CO_2)$ appeared that 4 schools among our sample target school exceeded in normal standard. 4 schools were almost similar with normal standard. TBC appeared that 7 schools among 11 schools were higher than standard. Noise measured school's mean value passed exceeded standard. And school which passed over standard appeared to 7 schools among 11 schools. HCHO was exceeded 4 schools by standard that excess and certainly interrelation between school's establishment year and facilities of construction was detected. PM10 was exposed all schools by fitness in standard. TVOC appeared that 9 schools among 11 measurement school was exceeded health effect standard of Japan.
