Objectives: To examine the complaint proportion and characteristics of musculoskeletal symptoms and to find risk factors of musculoskeletal symptoms among caterers for school lunch services. Methods: The study subjects were 385 caterers who were working for school lunch services in 71 elementary schools and 114 housewives who had visited a hospital for routine health check-up. A self-recording questionnaire was used to investigate the general characteristics, labor conditions, job stress and nature of musculoskeletal symptom. Caterers were surveyed from September to October in 2003 and the housewives during September by post. The ergonomic risk factors were examined for the caterers of an elementary school in Kyonggi Province in November, 2003. Results: The complaint proportion of self-reported positive musculoskeletal symptoms was 52.0% and that of severe musculoskeletal symptoms was 24.9%. Ergonomic assessment revealed that washing the dishes, carrying the soup containers and cleaning the sewage drain were highly risky activities in terms of repetitive and heavy weight-bearing motions. As for personal factors, the caterers having severe musculoskeletal symptoms had high psychological job demand. As for the workplace factors, the proportion of schools having severe musculoskeletal symptoms was significant higher where each caterer prepared more than 150 lunches. Among schools without school lunchroom, more schools had caterers having severe musculoskeletal symptoms. Using multilevel analysis, we found that the number of lunches to be prepared per caterer was a significant risk factor of severe musculoskeletal symptoms (O.R. 4.67). Conclusions: This study showed that the number of lunches prepared per caterer has a significant influence on the development of musculoskeletal disorder and that caterers work in an ergonomically highly risky job environment. The study results suggest that the number of caterers be increased to decrease the number of lunches prepared per caterer and the ergonomic environment be improved.

The purpose of this study was to study the effects of female oriented science curriculum and methodology on middle school girls` attitude toward science. This study utilized girl-friendly science content and method relating to electricity on middle school girls. The subjects of this study were 39 second grade female students in the experimental group and 38 second grade female students in a control group from a middle school in Seoul. The chapter `Electricity and Magnetism` of a middle school science II textbook was redesigned to reflect girl-friendly science content and method for the experimental group. These lessons using girl-friendly science content and method were conducted with the subjects of the experimental group while lessons from traditional textbooks with a lecture-centered pedagogy were conducted with the subjects of the control group for 6 weeks respectively. Before the research, a pretest about learning attitudes was given to both the experimental and control groups. And after the study, a post-test was also administered. According to the results of this study, there were significant differences between the experimental group and the control group and their respective attitudes toward science as it related to the lessons on electricity and magnetism. The use of girl-friendly science content and teaching approach had a positive effect on the experimental subjects affective disposition about the science lessons, science learning attitude(p<.05). For effective science teaching and learning to female students in middle school, further research and development on female students` learning styles and sequential studies for female friendly science curriculum and pedagogy are needed.

Objectives: The purpose of the present study was to estimate the prevalence of metabolic syndrome and to investigate the relation between metabolic syndrome and heart rate variability in a community population. Methods: The study design was cross-sectional, and 1028 subjects, aged 20~87 years, were recruited. Heart rate variability was measured in the sitting position for five minutes. The recorded data were assessed by time-domain (standard deviation of RR interval) and frequency-domain analysis. All subjects were examined for five components of metabolic syndrome. Results: The prevalence of metabolic syndrome in male and female subjects was 25.9% and 27.7%, respectively. The mean value of heart rate variability of the subjects was significantly different between healthy subjects and those with metabolic syndrome. The regression model showed that metabolic syndrome was negatively correlated with heart rate variability. Conclusions: The results demonstrate that metabolic syndrome has potentially negative effects on the cardiovascular system, and that these effects could be detected by heart rate variability. Follow-up studies able to control the cohort effect are necessary to evaluate the relation between metabolic syndrome and heart rate variability.

When building a testing environment with a testing platform, the configuration of test executor and its interface should be built to be appropriate for the system under test (SUT). That is, it is necessary to build the test executor and interface environment that can properly handle the input and output signals of SUT. If the testing platform is not extendable, it should be modified significantly whenever new SUTs and models are tested. It is a serious drawback that the test executor and interface configuration need to be modified depending on testing targets. To overcome the drawback, this paper proposes TEM(test Execution Machine), which allows for test executor to reconfigure its environment suitable to new SUTs by modifying the configuration file. The proposed TEM is verified through testing two real systems.
