This study examined the effects of safety-aisle on the safety climate, safety leadership, safety behavior, work loading and perceived accident risk in the small sawmilling industry. We distributed a questionnaire that measured various demographic variables, safety related variables by mail to 200 sawmilling companies. Finally 59 managers' and 129 workers' questionnaires were used for data analysis. An independent t-test was conducted to identify significant mean differences of safety related variables between safety-aisle installed and non-installed companies. Results indicated that mean differences of safety climate and safety behavior between safety-aisle installed and non-installed companies were significant. However, mean differences of safety leadership, work loading and perceived risk were not significant at the p < .05 level. Based on these results, the implications of this study and suggestions for future research were discussed.

In recent years, hazardous flash flooding has caused deaths and damage to infrastructure in Saudi Arabia. In this paper, our aim is to assess patterns and trends in climate means and extremes affecting flash flood hazards and water resources in Saudi Arabia for the purpose to improve risk assessment for forecast capacity. We would like to examine temperature, precipitation climatology and trend magnitudes at surface stations in Saudi Arabia. Based on the assessment climate patterns maps and trends are accurately used to identify synoptic situations and tele-connections associated with flash flood risk. We also study local and regional changes in hydro-meteorological extremes over recent decades through new applications of statistical methods to weather station data and remote sensing based precipitation products; and develop remote sensing based high-resolution precipitation products that can aid to develop flash flood guidance system for the flood-prone areas. A dataset of extreme events has been developed using the multi-decadal station data, the statistical analysis has been performed to identify tele-connection indices, pressure and sea surface temperature patterns most predictive to heavy rainfall. It has been combined with time trends in extreme value occurrence to improve the potential for predicting and rapidly detecting storms. A methodology and algorithms has been developed for providing a well-calibrated precipitation product that can be used in the early warning systems for elevated risk of floods.

기후변화로 인해 가뭄의 빈도, 심도 및 지속기간 등이 증가함에 따라 가뭄 위험도가 높아질 것으로 전망되고 있다. 가뭄 위험도는 수문기상학적 요인뿐만 아니라 용수의 공급 및 수요와 관련 있다. 최근에는 기후변화와 함께 사회경제적인 요인도 가뭄 위험도를 높이는 것으로 나타나고 있다. 따라서 미래에 발생가능한 심각한 가뭄에 적절히 대응하기 위하여 다양한 조건에서의 가뭄 위험도를 전망할 필요가 있다. 또한, 다양한 시나리오를 고려하는 것은 미래의 가뭄 위험도 전망이 가지는 불확실성을 줄이는데 도움이 될 것이다. 본 연구에서는 한국의 160개 시군구에 대한 기후변화 시나리오와 인구 및 용수 수요량 등을 고려하여 가뭄 시나리오를 작성하고 이에 따른 가뭄 위험도를 전망하였으며, 가뭄 위험도 전망 결과를 토대로 가뭄 위험 단계를 재설정하였다. 그 결과 한국의 가뭄 위험도는 과거에 비해 2020, 2025 및 2030년에서 모두 높아지는 것으로 나타났다. 특히, 기준 및 고위 시나리오에 따르면 2030년에는 가뭄 위험도가 과거보다 약 2배 정도 증가하는 것으로 나타났다. 본 연구에서 산정된 가뭄 전망 결과를 새로운 가뭄 위험 단계에 적용한 결과, 기준 및 고위 시나리오에서는 2020년 및 2030년에 한국 대부분의 지역에서 대응(V) 단계로 나타났다.

Globally, consumers' enormous and increasing appetite for meat is one of the biggest causes of climate change because livestock industry emits more greenhouse gas than transportation. The purpose of this study is to analyze consumer awareness about the impact of meat consumption on sustainability in response to climate change. Based on the theory of planned behavior, the attitudes, subjective norms, perceived behavioral control, prior knowledge, and risk perception variables were analyzed to evaluate the impact of climate change awareness over consumer behavior on meat consumption. Major findings are as follows: consumers were aware of climate change but has made few changes to their meat consumption. In addition, changes in meat consumption were found to be caused by health safety concerns, such as disease outbreaks. Significant variables related to meat consumption patterns associated to climate change impacts were household income, age, attitude, subjective norm, perceived behavioral control, and prior knowledge. These results suggest some implications for policy. There is a need for public relations and education to make the public aware of and better understanding of link between climate change and diet. Also, government should make efforts to raise awareness of mitigation of climate change such as comprehensive food labels which are identifying lesser impacts on climate and better dietary guideline instructions which would include coping with climate change.

Depending on the increased energy needs, a large number of dams have been built around the world. These dams have significant impacts on river ecology and climate change. When the climate change scenarios are examined, it is stated that the annual average temperature in Turkey will increase by 2.5-4 degrees in the future years, the south of the country will be opposed to the severe drought threat, and the northern regions will have a flood risk. In particular, it can be predicted that many dams and dam lakes built in the North of Turkey may increase the impact of climate change. In this study, the effects of the dams constructed in Çoruh basin on climate change are examined. Environmental and ecological problems of dam reservoirs have been examined. As a result of the data received from meteorological stations, it was determined that temperature and rainfall changes in the region. In this direction, solution proposal is presented.

The government should establish internationally harmonious regulations for effective import and export of necessary resources to other countries. However, the use and the number of pesticides used for the same purpose on same crops are depending on the soil and the climate where the crops are grown. Therefore, if internationally harmonized standards are difficult to establish, it is mandatory to conduct a risk assessment based on scientific data to reflect the domestic situation in order to avoid trade friction or conflict between countries. The government is preparing the implementation of a more regulated PLS (positive list systme) than the existing pesticide management system for safer pesticide management reflecting the recent increasing imported food, changing dietary habits, and changing climate. In order for effectively safe and scientific management of pesticides, the government should strive to communicate with consumers properly and the perception of pesticides by consumers should also be changed.

Background: The purpose of this study is to examine the combined effects of organizational climate (OC) with emotional labor (EL) on turnover intention in Korean firefighters. Methods: The data were obtained from the study Firefighters Research: Enhancement of Safety and Health. A total of 4,860 firefighters whose main duty was providing "emergency medical aid" were included. To examine the effects of OC on the relationships between five subscales of EL and turnover intention, four groups were created using various combinations of OC ("good" vs. "bad") and EL ("normal" vs. "risk"): (1) "good" and "normal" (Group I), (2) "bad" and "normal" (Group II), (3) "good" and "risk" (Group III), and (4) "bad" and "risk" (Group IV). Multivariate logistic regression analyses were performed to estimate the risk of turnover intention for the combinations of OC and EL. Results: The results showed turnover intention was significantly higher in the group with "bad" OC (17.7%) than in that with "good" OC (7.6%). Combined effects of OC and EL on turnover intention were found in all five subscales with the exception of Group I for emotional demands and regulation. Groups II, III, and IV were more likely to experience risks of turnover intention than Group I (p for trend <0.001). Conclusions: A positive and cooperative OC plays a role in decreasing the risk of turnover intention and in attenuating the negative effects of EL on turnover intention in firefighters.

Background: As the impact of climate change intensifies, exposure to heat stress will grow, leading to a loss of work capacity for vulnerable occupations and affecting individual labor decisions. This study estimates the future work capacity under the Representative Concentration Pathways 8.5 scenario and discusses its regional impacts on the occupational structure in the Republic of Korea. Methods: The data utilized for this study constitute the local wet bulb globe temperature from the Korea Meteorological Administration and information from the Korean Working Condition Survey from the Occupational Safety and Health Research Institute of Korea. Using these data, we classify the occupations vulnerable to heat stress and estimate future changes in work capacity at the local scale, considering the occupational structure. We then identify the spatial cluster of diminishing work capacity using exploratory spatial data analysis. Results: Our findings indicate that 52 occupations are at risk of heat stress, including machine operators and elementary laborers working in the construction, welding, metal, and mining industries. Moreover, spatial clusters with diminished work capacity appear in southwest Korea. Conclusion: Although previous studies investigated the work capacity associated with heat stress in terms of climatic impact, this study quantifies the local impacts due to the global risk of climate change. The results suggest the need for mainstreaming an adaptation policy related to work capacity in regional development strategies.

This study aimed to suggest an alternative income generation (AIG) for local artisanal fisheries communities in the southern coastal area of Bangladesh, which is vulnerable to climate change. To analyze the problems of local artisanal fisheries caused by climate change, field surveys and in-depth interviews with fishermen and government officials were conducted. Livelihood risk factor (LRF) in the marine fishing sector included reduction of fishing days and fish production and damage to fishing vessels and fishing gear due to cyclone and sea-level rise. LRF in the aquaculture sector included cultured fish escape, reduction of aquaculture production, and water pollution due to Monsoon flood. A common challenge for two sectors was high interest rate on commercial loans. Small-scale tank aquaculture is recommended as AIG for securing income of artisanal fisheries communities. In the early stages of dissemination of small-scale tank aquaculture technology, it is necessary to prevent fishermen from struggling to repay high-interest rate loans through technology transfer and facility support by official development assistance. The aquaculture training center, along with the technical education, will also contribute toward expansion of local distribution network and marketing support to establish a value chain for local artisanal fisheries communities.
