This study conducted a survey on recognition of teachers, students, and Parent Teacher Association(PTA) for the Education for Sustainable Development from April to October, 2008. It confirmed a couple of facts, which were summarized as follows; First, among eight educational areas including Environmental Education, Energy Education, Gender Education, World Heritage Education, Multi-cultural Coexistence Education, Peace Education, Education for human rights, and Education for international understanding that UNESCO had offered, this study showed that the 'Environmental Education' is a relatively important area comparing with others. Second, 54.4% of the respondents have agree with the need of the education for sustainable development in the middle school and the high school, and 54.1% of them showed their willingness to participate in the program. Third, because 49.2% of the respondents chose 'important' on the question of 'how important the field education and the experience education are', it looked like most of them agreed with the importance of the field education and the experience education. Fourth, because 61.1% of the responded teachers chose 'need' on the question of 'if it needs relationship with other studies', it looked like most of them agreed with the necessity of relationship with other studies. Fifth, 62.5% of the respondents chose 'no' on the question of 'if they conduct the education for sustainable development Even if some wanted the education for sustainable development, most of them would not do it in the regular curriculum, but in the special activity class or teacher's discretional time. Sixth, most respondents indicated the teacher's class burden and the teacher's lack of knowledge as the problem if the education for sustainable development would be conducted. This result implied that in order to vitalize the education for sustainable development, the teacher's class burden should be reduced and the teacher train program is necessary. Finally, urgent requested studies could improve the education for sustainable development in communities and schools, because the result of the survey showed education, natural observation learning, and visiting ecological parks as important elements.

Purpose: The purpose of this study was to examine the relationship between perceived job stress and work environmental factors related with socioeconomics factors and physical burden in the golf caddies. Methods: Job stress in golf caddies was estimated by using the Karasek's job content questionnaire (JCQ) and work environmental factors were estimated by self-reported questionnaire and interview. Results: The subjects were 316 woman caddies who had never been occupationally exposed to hazardous chemicals, was mean age 31.1 years. Mean work duration was 6.44 years and working hours per day on low- and high-demand season were 6.16 and 10.51, respectively. The golf caddies displayed higher scores of job stress due to multiple factors such as working hours and frequency of rounding per week, physical burden, confliction, income satisfaction and employment stability. We found that high strain group was positive correlation with age, career, working hour (including frequency of rounding) and job demand, however, showed negative correlation with job decision latitude and support of supervisor and coworker. Conclusion: In conclusion, we suggest that the golf caddies be regard divided into high strain group as appropriate. Thus, stress management and health promotion program for golf caddies should be developed.

A survey was conducted to 890 radiological technologists working at 44 general hospitals of 16 cities and provinces across the county to determine their stress level according to regions divided into the capital city, metropolitan areas and small- and medium-sized cities. For this purpose, such factors as their working environment, role playing, job conflict and job burden were compared and analyzed according to the regions. The findings may be summed up as follows: 1. In terms of working environment, radiological technologists in the capital city were found to have the least stress(23.46), followed by those in metropolitan areas(24.53) and small- and medium-sized cities(24.85). There was a significant difference according to the regions as for the item 'worry about influence of radioactive contamination(genetic, decisive and plausible)(P<0.001). 2. As for role playing, radiological technologists in small-and medium-sized cities appeared to receive the highest stress(l8.25) followed by metropolitan areas(l7. 71) and the capital city(l6.69). There was a statistically significant difference(P<0.001) according to the regions 3. Regarding job conflict, those who work in small- and medium-sized cities turned out to get the highest stress(15.66) compared to those in metropolitan areas(15.35) and the capital city(l4.44). In terms of job autonomy, there was no significant result from the survey in spite of the difference between metropolitan areas(14.87), small- and medium-sized cities(l4.79) and the capital city(l4.66). 4. Little difference was detected according to the regions as far as the job burden(excessive or too little) was concerned. But their was a significant regional difference in tenns of patient-related factors with the capital city(11.50), small- and medium-sized cities(l0.75), and metropolitan areas(1.63)(P<0.001).

Objectives: The purpose of this study is to analyze the recent trends in patients with work-related musculoskeletal disorders in South Korea and to check the major results by reviewing the literature on the risk factors and prevalence of musculoskeletal diseases related to work. Methods: Industrial disaster data from the Ministry of Employment and Labor from 2012 to 2021 were used, and the literature was reviewed regarding risk factors for musculoskeletal diseases related to work using PubMed and RISS. Results: The trend of patients with work-related musculoskeletal disorders has increased overall since 2017 after declining until 2016, with a particularly notable increase in the average annual number of patients with physical burden work. The average annual rate per ten thousand people for patients with body burden work, non-accidental lower back pain, and carpal tunnel syndrome among work-related diseases was high in the mining industry. The average annual rate per ten thousand people for patients with accidental lower back pain was the highest in the fishing industry. Within the manufacturing field, it was the highest in the shipbuilding and ship repair industry. As a result of the literature review, the search rate for work-related musculoskeletal disease papers in unstructured work was high. In addition, physical stress factors were high among risk factors, and pain areas showed a high rate for the waist. Conclusion: Even after the institutional implementation of a hazard investigation system related to musculoskeletal diseases is implemented, the number of patients with occupational musculoskeletal disorders continues to increase. Therefore, it is necessary to conduct regular surveys and implement effective improvement activities for vulnerable industries or occupations.

Objectives: In establishing policies for agricultural safety, evaluating injury burdens as well as investigating the rates and characteristics of work injury is important. This study investigated the types and characteristics of agricultural injury subjective burdens. Methods: By analyzing the injured farmers identified in the 2013 Korean Farmers' Occupational Injury Survey, the burdens caused by injuries were categorized using one direct cost item (medical costs) and five indirect cost items (including productivity decreases and wage increases). Statistical differences among the burden items were analyzed using logistic regression analysis according to the characteristics of the farmers and their farm injuries. Results: Among the subjective burdens indicated by the 457 injured farmers, disruption to work was most common. The major influences on each subjective burden item are as follows: for the item of disruption to work, age, time of injury occurrence, treatment period, and farming machine use were influential; for an increased family member's burden of farm works, the number of family members and treatment period were influential. Regarding cost burden of treatment, the results varied according to whether or not the patient was hospitalized and annual income. Conclusion: Subjective burdens induced by indirect costs rather than those induced by direct costs were found to be higher in ratio. In regard to each burden item, the results varied according to the characteristics of the farmers and their farm injuries. To support injured farmer, setting goals to reduce indirect cost burdens and preparing concrete methods is necessary.

The use of chlorinated water in swimming pools produces elevated chloroform levels in the water and air of the pools which can cause chloroform body burden of swimming individuals. Present study confirmed the chloroform body burdens from a 40-min swimming and evaluated the decay of chloroform breath concentration after the cessation of a 60-min swimming. Air and water concentrations were measured in the pools. The water and air chloroform concentrations ranged from 18.1 to 25.3 ${mu}g/l$ and from 30.9 to 60.7 ${\mu}g/m3$ for the confirmation study, respectively. The breath level after 40-min swimming was about 64 to 266 folds higher than the corresponding background breath. The breath concentration after the 40-min swimming ranged from 10.5 to 21.3 ${\mu}g/m3$, while that prior to the corresponding swimming ranged from 0.07 to 0.19 ${\mu}g/m3$. In addition, the post-exposure breath level varied with the subjects who swam in the pool on the same visiting day. Breath concentration increased gradually during 60-min swimming, then decreased rapidly within 5 minutes after the cessation of exposure, after that, decreased slowly, and finally approached to a background breath level at 1-2 hr after exposure.

A life cycle impact assessment was applied in an industrial waste incineration plant to evaluate the direct and indirect environmental impacts based on toxicity and non-toxicity categories. The detailed life cycle inventory of material and energy inputs and emission outputs was compiled based on the realistic data collected from a local industrial waste incineration plant, and the Korean life cycle inventory and ecoinvent database. The functional unit was the treatment of 1 tonne of industrial waste by incineration and the system boundary included the incineration plant and landfilling of ash. The result on the variation of the impact by the unit processes showed that the direct impact was decreased by 79.3, 71.6, and 90.1% for the processes in a semi dry reactor, bag filter, and wet scrubber, respectively. Considering the final impact produced from stack, the toxicity categories comprised 91.7% of the total impact. Among the toxicity impact categories, the impact in the eco-toxicity category was most significant. A separate estimation of the impact due to direct and indirect emissions showed that the direct impact was 97.7% of the total impact. The steam recovered from the waste heat of the incineration plant resulted in a negative environmental burden.

Facing the issue of global climate change, it is important for environmental educators to prepare a person who is able to understand of, communicate about, and make informed decisions on the climate change. Climate change education is to help learners understand of human influence on climate and climate's influence on them and society. This study was conducted in a way to discuss how climate change education could be implemented in Korean context. For this purpose, several documents and research articles on climate change education and communication were analyzed: Climate literacy, guidelines for K-12 global climate change education, and guidelines for effective climate change communication and message and so on. Many of the documents emphasize age appropriateness, positive thinking, participation and empowerment in climate change education while suggesting not to burden young learners with fears. Some documents such as the climate literacy suggest key concepts and/or essential principles of climate change education. Based upon the analysis, several considerations to incorporate the concepts in climate change into educational programs were suggested for further discussions.

Heat stress is a significant burden to animal production in most areas of the world. Improving our knowledge of physiological and metabolic mechanisms of acclimation may contribute to the development of procedures that may help to maintain health and production efficiency under hot temperature. The effect of Ulmus pumila (UP) extract in inducing Heat Shock Proteins (HSPs) expression in heat-stressed RAW264.7 macrophage cells was investigated. Cell viability assay showed a dose dependent increase in cells after treatment with UP for 24 hours. RT-PCR and western blot analysis showed that increasing concentrations of UP induce the expression of Heat Shock Factor 1 (HSF1) and dose dependently upregulated the expression of Heat shock protein 70 (Hsp70) and Hsp90. LPS-induced nitric oxide was dose-dependently reduced while phagocytic activity greatly recovered with UP treatment. These data demonstrated that UP can be a potential candidate in the development of cytoprotective agent against heat stress.
