Background: As social distancing persists and interest in work-life balance grows, more companies are adopting flexible work policies. While there have been studies on sleep disorders associated with different types of work, such as shift work, research exploring the relationship between flexible work schedules and sleep disorders is still limited, particularly among Korean workers. Methods: We performed a secondary analysis of the 6th Korean Working Conditions Survey, focusing on 31,243 paid workers out of a total of 50,538 participants. We defined flexible workers as those who set their own working hours. Sleep disorders were divided into three categories: 'difficulty falling asleep,' 'frequent waking during sleep,' and 'waking up feeling exhausted and fatigued.' Using scores derived from three specific symptoms, the Minimal Insomnia Symptoms Scale (MISS) was calculated to assess the prevalence of insomnia. We used chi-square tests to analyze demographic and job-related differences. A multivariate logistic regression analysis was employed to identify any relationship between flexible work schedules and sleep disorders. Results: Significant differences were found between flexible and non-flexible workers regarding age, income level, education level, and job type. Flexible workers reported sleep-related symptoms significantly more often. The odds ratio for insomnia was 1.40 (95% CI 1.21-1.61). For males, the odds ratio was 1.68 (1.36-2.08). Conclusion: This study establishes a correlation between flexible work schedules and sleep disorders among Korean salaried workers. Potential causes could include changes in circadian rhythm, increased work demands, and extended working hours. To precisely determine causality and associated diseases, further research is required.

‘Environmental Literacy’ is defined as ‘one's individual status to be accomplished or to be acquired by environmental education’ and it has the same meaning as ‘the Goals of EE’. The purposes of this study was to identify the components of environmental literacy and analyse the related studies. Much of the work in EE has followed the path outlined by the Belgrade Charter, the Tbilisi Declaration, and later in Agenda 21. Over the years, scholars such as Hungerford et al., Iozzi et al., Roth, the Wisconsin Center for Environmental Education, and the Environmental Education Literacy Consortium have examined and proposed a framework of ‘Environmental Literacy’. Recently, the influential framework developed by the NAAEE(the North American Association for Environmental Education) National Project for Excellence in EE included seven categories: affect, ecological knowledge, socio-political knowledge, knowledge of environmental issues, skills, additional determinants of environmentally responsible behavior, and environmentally responsible behaviors. According to the analysed results, 37.7% of the American studies and 32.5% of Korean ones measured aspects of the attitude. Especially, the measure of this variable in America, however, led to the most inconclusive and least positive outcomes. The studies included related to cognitive skills were very few but 100% reported positive impacts of instructions in two countries. In America, using a television documentary, a journal and the field trip were very useful and effective. But using a computer simulation/game was less effective and the supplemental instruction did't led to the positive effect. In Korea, instruction, the supplemental instruction and EE program led to positive outcomes generally. The lack of validity and reliability of the instruments was pointed out as a common problem and the development of valid and reliable instrument for nation-wide assessment is urgently needed.

The aim of this study is to explore the meanings and significance of sense of place in environmental education. Sense of place is related to affective aspect of human, means emotional bonds to place where he live. In general sense, place is referred to a location on the earth but is not confined to physical settings or space. It is a construction reflecting human experiences and meanings and being center of meaningful experiences in everyday life. Recently there are many environmental educators emphasizing lived experience as a way to develop environmental sensitivity or intimacy toward nature. Environmental education should be practiced in the place where the participants live and reflect locality including social and cultural characteristics as well as natural features. In addition, it should provide opportunities for participants to have an lived experience where they can get the sense of bonds to place or connectedness. It is the significance that sense of place has. If you get sense of place, sense of bonds to place, you are likely to feel much more belongingness and attachment to place, which in turn become a basis for a variety of activities to conserve and improve the place and will develop an ecological self.

While global warming and climate change have been issues with global implications for ecology and nature as well as for the economy, politics and social sector, Korean's climate change awareness has been reported to be low. This phenomenon can be attributed to the fact that there is neither a systematic and continuous educational program for climate change nor a system to implement and support it. Although environmental education traditionally has not been a center of focus in most schools, the move towards "green growth" in national policies are slowly influencing school education as well. Throughout the year 2009, Green Suncheon 21 has offered a program called 'Suncheon Climate School' designed for elementary schools and regional centers for underprivileged children. Program instructors were sent to schools and centers that requested such climate change education. The aim of this study is to evaluate the success of the program and to provide feedback on its impacts. According to the study, students' interests in climate change have increased after the climate change education, and students found the lectures to be informative and interesting. Students said that they became more aware of the serious consequences of global warming and climate change and found that such education is beneficial and should be available to a wider population. This study suggests that first, school teachers should be aware of climate change and support such educational programs to be a part of the regular curriculum. Second, the content and the level of the program should be designed in consideration of the corresponding school curriculum to make the subject relevant and accessible to students.

Objectives The aim of this study was to determine the association between low-level mercury exposure and neurobehavioral functions in adults living in coastal regions of Korea. Methods We selected 172 adults aged 20-65 years living in a city in the coastal region of Korea. A sociodemographic survey was conducted, mercury levels in the blood, urine, and hair were measured, and the associations according to computerized neurobehavioral tests were determined using univariate analysis. After adjustment for associated variables, a multivariate linear regression analysis was performed. Results The geometric mean mercury levels in the blood, urine, and hair were $5.41{\mu}g/L$ (range, $0.00-15.84{\mu}g/L$), $1.17{\mu}g/g$-creatinine (range, $0.00-32.86{\mu}g/g$-creatinine), and 1.37 mg/kg (range, 0.42-6.56 mg/kg), respectively. Variables that were associated with simple reaction time according to the neurobehavioral test results were age and urine mercury level. Variables associated with choice reaction time were the recent use of Korean traditional medicine and urine mercury level. Variables associated with the right-hand finger tapping speed test were age, gender, smoking behavior, education level, monthly household income, and urine mercury level. Variables associated with the left-hand finger tapping speed test were age, gender, education level, and urine mercury level. After adjustment for associated variables, there was no significant association between urine mercury level and simple reaction time (${\beta}=25.96$; p =0.47), choice reaction time (${\beta}=50.37$; p =0.32), or the number of left-hand finger taps (${\beta}=-1.54$; p =0.21). However, urine mercury level was significantly associated with the number of right-hand finger taps (${\beta}=-3.86$; p =0.01). Conclusions We found no evidence that low-level mercury exposure in adults is associated with deficits in neurobehavioral functions. A longer follow-up study is required to confirm this conclusion.

Obesity may be the consequence of various environmental or genetic factors, which may be highly correlated with each other. We aimed to examine whether grandmaternal and maternal obesity and environmental risk factors are related to obesity in daughters. Daughters (n = 182) recruited from female students, their mothers (n = 147) and their grandmothers (n = 67) were included in this study. Multivariable logistic regression was used to analyze the association between the daughter's obesity and maternal, grandmaternal, and environmental factors. Maternal heights of 161-175cm (OD: 8.48, 95% CI: 3.61-19.93) and 156-160 cm (2.37, 1.14-4.91) showed positive associations with a higher height of daughter, compared to those of 149-155 cm. Mothers receiving a university or a higher education had a significant OR (3.82, 1.27-11.50) for a higher height of daughter compared to those having a low education (elementary school). Mother having the heaviest weight at current time (59-80 kg, 3.78, 1.73-8.28) and the heaviest weight at 20 years of age (51-65 kg, 3.17, 1.53-6.55) had significant associations with a higher height of daughters, compared to those having the lightest weight at the same times. There was no association between the height, weight, and BMI of daughters and the characteristics and education of her grandmothers. In conclusion, although genetic factors appear to influence the daughter's height more than environmental factors, the daughter's weight appears to be more strongly associated with individual factors than the genetic factors.

The international environmental activity and environmental education began in 1970's. Environmental education in Korea was emphasized since the Forth National Curriculum. The Environmental Curriculum was regarded as one of the most important part in the Sixth National Curriculum in Korea. Environment-related reference texts of Elementary school were already developed. Soon, 'Environment' of middle school and 'Environmental Science' of high school will be developed. The purpose of this study were to analyse environment-related texts in the Fifth National Curriculum and to measure how much environmental education has achieved. As a environmental text for regular class, selected the environmental part in 'Science Part 1' and as environment-related reference text, 'Survival and Environment'. The environmental part of 'Science Part 1' was unit [Life and Environment]. According to the analysis of objectives, most of unit objectives were not stated in a detailed and precise manner. When the goals of environmental education were divided into four fields as follows, knowledge and information, skill, thinking and attitude, behavior and participation, unit objectives were mostly emphasized on knowledge and information of environment, exactly 44.5% of unit objectives and 89.6% of subunit objectives. The degree of relationship between unit objectives and contents was low. All the Check up-problems were about knowledge and information of environment. Environment-related reference text, 'Survival and Environment' was the only reference text for high school students in Korea and was organized in the form of the regular curriculum text. It was developed in Korean Education Development, Center with support of Korean Environmental Ministry in 1990. According to the analysis of 'Survival and Environment', the objectives of units and subunits were less stressed on knowledge and information than those of unit [Life and Environment] in the environmental part of 'Science Part 1' On the other hand, they were a little more stressed on skill, thinking and attitude, behavior and participation. And fifteen of all the seventy subunit objectives were not related with contents. In organization, this text included Thinking problems, Experiments and Inquiries, Reading, Developed studies and Check up-problem etc. It was remarkable that Inquiries leaded to individual activities and Developed studies to group discussions or individual inquiries. And as Check-up problems were presented as a form of activities, students could achieve many various objectives at the same time by solving one problem. To measure the achievement of environmental education by questionnaire, 497 high school students in total were selected from five different schools. Scores in subtest 'behavior and participation' and subtest 'thinking and attitudes' were 13.19 and 18.18, respectively. Actually, most students had a positive thinkings and attitudes in their hearts about environmental problems, but many of them actually did not take actions to solve environmental problems and to protect environment. Scores in subtest 'knowledge and information' and subtest 'skill' were 10.76 and 10.81, respectively. The higher the score students got in 'knowledge and information', the higher the score in 'skill'. It implies that learning of skills is based on learning of knowledges and informations about environment has not always ensured positive thinkings and attitudes or active behaviors and participations to solve environmental problem.

This study aims to find the perception and utilization of the citizen about the dryness watch warning (DWW) among special weather reports. For this we have made up a descriptive questionnaire including the perception, utilization of special weather reports. Using the SPSS 17.0 program, descriptive statistics, t-test, ANOVA and Scheffe test were used to analyze the collected data. The results are as follows; The perception of DWW is measured by 4 point Likert scale and the average is $15.97{\pm}3.70$ (percentile=57.0). This value shows that the awareness level is not that high and according to the occupation, college students show the lowest awareness and housewives show the highest awareness. According to the age, the teens and twenties show the lowest awareness and fifties and sixties show the highest awareness. Although the perception of the teens and college students are rather poor, there were many positive answers that it is necessary to establish the advanced disaster prevention plan according to the questionnaire about the utilization of DWW. Therefore, if we come up with an effective plan to improve the perception than we can expect a large-effect in terms of fire and forest fire prevention. The perception of DWW can be improved by providing weather information and weather related education program on TV or internet which have the high level of preference. Also, it is necessary to provide online and offline program of advertising education and disaster management education through the weather forecast bureau which is the host organization of delivering weather information.
