  • This study analyses the factors that affect the satisfaction of school meals program. To obtain the data, 54 elementary, middle and high schools in Jeonbuk area were chosen for survey. A ordered probit model analysis is conducted to identify the key explanatory variables that affect the satisfaction of school meals about elementary, middle and high school's students. Also, a ordered probit model is used to calculate marginal effects of several key variables. The study finds that key factors that affect to increase the satisfaction of school meals are rural area schools, elementary school's students, and education for school meals or food nutrition. The satisfaction of school meals in urban and rural school's students are significantly different. Also, the satisfaction of school meals about elementary, middle and high school's students are significantly different. To do this, importance of school meals is to build up the safe agricultural supply system. For safe agricultural supply system, local agricultural products provided in school meals should be supplied based on GAP, HACCP certificated companies such as US FTS(Farm to School) program.

  • The purpose of this study is to investigate allergic diseases related to allergy caused by the exposure to indoor and outdoor sources of air pollution in primary schools. The symptoms questionnaire of allergic diseases based on the International Study of Asthma and Allergies in Childhood (ISAAC) was completed by the participants. The past and present status of asthma, allergic rhinitis, eczema, and allergic conjunctivitis were investigated by providing a questionnaire to all the participating children. Questionnaires were sent to a total of 61,350 children from 438 primary schools. A total of 40,522 children responded to the questionnaire, which represents a 66.1% return rate. Volatile Organic Compounds (VOCs), $\underline{A}$ldehydes, and Particulate Matter ($PM_{10}$) were measured and analyzed from October to December of 2006, in 82 primary schools. The final study population comprised 35,168 children with complete data which excluded incomplete questionnaire responded by 5,354 children. Based on the survey, the level of indoor air contamination did not appear to be high, but 27.2% of the schools evaluated had exceeded the $PM_{10}$ level specified by the school health guidelines ($100\;{\mu}g/m^3$). The overall mean concentration of formaldehyde was $22.07\;{\mu}g/m^3$ and 1.0% of schools (1 school) exceeded the $100\;{\mu}g/m^3$. Statistically significant relationships have been observed between indoor air quality and prevalence rate of allergic rhinitis and conjunctivitis of primary schools in Korea.

  • Antitumor polyacetylenic alcohol, panaxytriol (Cl7 H26O3), was isolated and purified from a powder of the root of Pnnnx tin.1.encl C.A. Meyer. Panaxytriol possesses unusual property of being soluble in both water and organic solvents. Panaxytriol inhibited the growth of various kinds of human cultured cell lines in dose-dependent fashion in vitro. The in vivo effects of panaxytriol were tested against C57BL/6 mice transplanted with Bl6 melanomas. Panaxytriol (8 and 40 mg/kg) administered intra-muscularly(im) produced significant tumor growth delays in mice. Although a detailed mechanism of growth inhibition by panaxytriol is unknown, preliminary results appear to implicates a surface membrane site of action. And its action seems to be more dose-dependent than time-dependent. Finally, panaxytriol pharmacokinetics was evaluated in mice given single 8 mg/kg doses intraperitoneally (ip) or im. Serum panaxytriol content was measured using both tumor growth inhibitory assay and a gas chromatographic method. The maximum serum panaxytriol content after ip and im administration was 35.0 and 1.6 $\mu$g/ml respectively. These results indicate that the compound may act as cytotoxic substance even in patients.

  • This study considers the concept of schools and their spatial composition by John Dewey through literature review who argued for a new, children-centered education in the early 19th century, and it also mentions some suggestions for improvement of the elementary school facilities in Korea that the size and number of students in school has decreased sharply. John Dewey claimed that a school is a big household as well as a small society in which one studies the current occupation and experience in connection between the household-school-society. At the same time, he pursued an organic and open spatial composition which can effectively and efficiently enable educational curriculum's application, social occupation and project learning based on children's native impulse and stage in child growth. Korea's education policy should shift from quantity-based education production to quality-based production due to the reduction of school age population among other reasons. Especially this study emphasizes that small size schools need to be changed to local community facilities with environment-friendly, children-centered and open learning spatial composition with basis on John Dewey's educational philosophy.

  • Purpose: This study was conducted to describe the experience of school health teachers in regard to the COVID-19 pandemic in South Korea. Methods: We conducted a qualitative study using content analysis. Ten school health teachers were recruited from 6 elementary schools, 2 middle schools and 2 high schools in Seoul, using purposive sampling. They participated in semi-structured in-depth interviews in person or using an online communication system from January to February, 2021. Interviews were transcribed verbatim and analysed using qualitative content analysis. Results: Three main categories and nine generic categories emerged from the analysis. Firstly, it was discovered that school health teachers had psychological and physical stress to cope with COVID-19 due to the 1) fear of the unexpected infectious disease, 2) burden of having to deal with it alone, 3) breakdown of personal life and physical exhaustion and 4) heavy duty as a health teacher caused by the lack of an organic cooperation system with institutions related to school infectious diseases. Secondly, school health teachers had an increased sense of empowerment in regard to infectious disease management as a result of 1) feeling rewarded and appreciated and 2) gaining confidence and trust in infectious disease management. Finally, school health teachers experienced the urgent need for an effective response strategy for infection control because of the 1) confusion over infectious disease response due to lack of practical manuals applicable to the field as well as training, 2) disappointing response system without an expert response team dedicated to managing infectious diseases in schools, and 3) growing awareness of the need for change. Conclusion: It is expected that school health teachers' experience of COVID-19 will be used as important data for building effective and advanced school infectious disease response systems.

  • The purpose of this study is to examine the health of beauty salon workers through the utilization of questionnaires concerning the extent of exposure to organic solvents found in the air of some beauty salons and any resultant symptoms in employees. The subjects were 36 employees from 10 beauty salons who agreed to participate in this study. The degree of exposure to organic solvents in the air of beauty salons was measured from September 1, 2008 to September 30, 2008. A survey of symptoms that occurred due to exposure to these solvents was also performed. The results were as follows: questionnaires were collected and analyzed from a total of 36 subjects. Of these, 28(77.8%) were female and 8(22.2%) were male. The mean age was 29.08. The mean working period was 7.13 years. Sixteen subjects attended programs at universities while 11 went to beauty schools for vocational education. When testing the concentration of organic solvents in the air of beauty salons, the highest value found was Isopropyl alcohol 511.85 ppb followed by butyl acetate, toluene, acetone, xylene, ethyl benzene, styrene, and chlorobenzene. A logistic regression analysis was performed as follows: the point of each factor was the dependent variable while sex, age, drinking, smoking, educational level, work experience, hairdresser's license, and organic solvents were the independent variables. Statistically significant difference (p<0.05) was shown in the hairdresser's license among Factor 1 and in Xylene among Factor 2; however, difference was not shown in the other variables.

  • Indoor air quality has been addressed as an important atmospheric environmental issue and has caught attention of the public in recent years in Korea. Good indoor air quality in classrooms favour student's learning ability, teacher and staff's productivity according to other studies. In this study, each classroom at four different schools was chosen for comparison of indoor and outdoor air quality by means of source generation types such as new constructed classroom, using of cleaning agents and purchased furniture. Temperature, relative humidity (RH), carbon dioxide $(CO_2)$, formaldehyde (HCHO), total volatile organic compounds (TVOCs) and particulate matter with diameter less than $10{\mu}m\;(PM_{10})$ were monitored at indoor and outdoor locations during lesson. HCHO was found to be the worst among parameters measured in new constructed classroom, HCHO and TVOCs was worst in classroom with new purchased furniture, and TVOCs was worst in classroom cleaned by cleaning agents, Indoor $(CO_2)$ concentrations often exceeded 1500 ppm indicating importance of ventilation. Active activity of students during break time made the $PM_{10}$ concentration higher than a lesson, Improvements and further researches should be carried out considering indoor air quality at schools is of special concern since children and students are susceptible to poor air quality.

  • The purpose of this study is to help examine the nature and direction of today's village education community by examining the characteristics of Osan School and Myeongdong School, which were representative national schools during the Japanese colonial period, as village education communities. These two schools were prestigious private schools that became the bases for national and international independence movements at home and abroad. The fact that these schools were able to produce excellent graduates by faithfully carrying out the national education, which was the mission of the time, despite the oppressive situation, was influenced by the village education community formed by the organic cooperative relationship between the school and the village. The two schools have had active support from the village since their establishment, and the schools invited villagers if there was a good educational opportunity or cultural event. The school opened all the facilities of the school to the residents, and the villagers took care of the students and teachers, forming a close fusion between the two sides. Based on this relationship, the school and village made an effort to create an ideal village community based on independence, equality and solidarity. As such, the historical examination of Osan School and Myeongdong School suggests implications that help the village education community move forward to a more mature stage.
