Objectives: The aim of this study is to investigate microbial contamination in the school food service environment for the assessment of microbial food safety. Methods: We collected both swab samples from tables and desks and airborne bacterial samples from an elementary school (School A) and a high school (School B). Heterotrophic plate count, total coliform, Staphylococcus aureus, and Bacillus cereus were measured with selective media to quantify microbial concentration. PCR assay targeting 16S rRNA genes was performed to identify the strains of S. aureus and B. cereus isolated. In addition, we made a food service checklist for the locations to evaluate the food service environment. A Wilcoxon test was employed to examine the differences in microbial concentration between before lunchtime and afterwards. Results: Heterotrophic plate counts showed higher levels after-lunch compared to before-lunch at School B. However, levels of S. aureus were higher in the after-lunch period (p<0.05) in both classrooms and in the cafeteria in School A. B. cereus was only sparsely detected in School B. Several samples from food dining carts were found to be contaminated with bacteria, and facilities associated with food delivery were found to be vulnerable to bacterial contamination. Although microbial concentrations in the air showed little difference between before- and after-lunchtime in the cafeteria in School A, those in classrooms were greater after-lunchtime at both schools. Conclusion: Our results suggested that the microbial safety in schools after lunchtime of concern. Necessary preventive measures such as hygiene education for students and food handlers should be required to minimize microbial contamination during food service processes in schools.

The purpose of this study is to define the difference in the self-concepts between the public and the private primary school students. The data were collected from March 16 to 20 in 1994. The objects of this study are the 5th graded primary school students, total 193, from the public (94 students) and private (99 students) schools located in Chong Ju city. The tool used for this study is SDQ (Self Description Questionnaire). The SDQ is a multidimensional instrument designed to measure seven aspects self-concept hypothesized in Shavelson's hierarchical model. The collected data were analyzed using descriptive statistics, chi-square test, t-test and 2-way ANOVA. The results of the study are as follows: 1. Between the public students and the private students there were no significant differences in the self-concept. 2. 2-way ANOVA using sex (male vs. female) and type of school (public vs. private) were performed. The boys had substantially higher self-concepts in physical ability and the nonacademic self concept. The girls tended to have higher self-concepts for the academic factors (except for Mathematies). 3. 2-way ANOVA using social stratification (upper vs. lower) and type of school (public vs. private) were performed. The upper classes tended to have higher self-concept for the academic factors. The social stratification and sample interactions were statistically no significant.

Public perceptions of nanotechnology and its potential risk can be an important measure for the sustainable advances of the technology. We conducted a survey for public (N =599) and experts (N = 165). They answered the same questions and results were analyzed. 74% of the public have not heard about the potential risk of nanotechnology and 77% expected that nanotechnology/materials are not harmful to the human and nature. 74% of experts realized the potential hazards by nanomaterials. The results represented that large perception gab between public and experts has existed in Korea. Interestingly, Korean public thought that nanotechnology is more profitable and less risky than that of American. We suggest that 'now is the best time to give appropriate information on the potential risk of nanotechnology to Korean public without preconception or exaggeration.'

The authors compared the basic characteristics of rural woman in relation to family planning for June 1967 and June 1969 in Kyung San County, Kyungpook Province, Korea. The statistics showed that these characteristics are gradually changing. The marriage age was slightly higher than the past year and the formal education of women increased. The ideal children number, and the gravidity and mortality rates decresed. At the same time the number of induced abortions, the knowledge of family planning, and the acceptance rate of contraception increased. These phenomena seem to follow the present worldwide trend.
