These actions may be represented by sheltering, evacuation, distribution of stable iodine tablets and/or relocation. This study represents a comprehensive probabilistic study to investigate the role of the adoption of the countermeasures in case of a hypothetical accident of type LOCA for nuclear power plant of PWR (1000 Mw). The effective doses in different organs, short and long health effects, and the associated risks are calculated with and without countermeasures. In addition, the overall costs of the accident and the costs of countermeasures are estimated which represent our first trials to know how much the proposed accident cost. The results showed that, the area around the site requires early and late countermeasures action after the accident especially in the downwind sectors. For late countermeasures, the duration time of relocation ranged from about two to 10 years. The adoption of the countermeasures increases the costs of emergency plan by 40% but reduces the risk associated the accident.展开更多

The questionnaire is sent to a sample of external auditors from Malaysian Big Four (Klynveld Peat Marwick Goerdeler (KPMG), Ernst and Young, Deloitte KassimChan, and PricewaterhouseCoopers (PwC)) main offices. There are 167 useable responses. The regression results have provided evidence that ethical climate is directly, significantly, and positively associated with job satisfaction. In contrast, ethical climate appeared not to be directly related with external auditor's turnover intention. Both job satisfaction and organizational commitment were identified as significant predictors in explaining turnover intention, since they had a significant and negative effect on external auditor's turnover intention. This study also implied that job satisfaction had a significant effect on organizational commitment. Furthermore, the findings revealed that organizational commitment partially mediated the relationship between job satisfaction and turnover intention. The results extend the literature on external auditor's turnover intention and provide insights for human resource management in accurately assessing employee's turnover intention in order to improve retention and reduce actual turnover particularly in audit firms.展开更多

For the mitigation of ATWS (anticipated transients without scram) as well as CCF within the PPS (plant protection system) and the ESF-CCS (engineered safety feature-component control system), the ADPS (advanced diverse protection system) has been developed by KEPCO E & C (KEPCO Engineering and Construction) Company for new nuclear units in Korea. As compared to the DPS (diverse protection system) design of APR1400, the ADPS has a diverse safety injection function considering a LBLOCA (large break loss of coolant accident) concurrent with the CCF of the PPS and ESF-CCS. Besides the function of SIAS (safety injection actuation signal) initiation, several CCF avoidance features, such as the changes of software design classification, communication methods, equipment platform, and man-machine interfaces, are introduced to enhance the reliability of the ADPS. In addition, the ADPS has recently incorporated four redundant channels with 2-out-of-4 voting logics to enhance its fault tolerant capability. Therefore, it is expected that the ADPS can provide an enhanced reliability regarding possible CCFs in the safety-grade digital I & C systems as well as the ADPS itself.展开更多

Pedestrians have been considered as a high-risk group among road users, especially in middle- or low-income communities. This study attempted to determine the burden of pedestrians' fatalities in Fars, the southern province of Iran using years of life lost (YLL) approach. Methods: The data used in this study were retrieved from Fars Forensic Medicine Organization database on pedestrian traffic accidents. The YLL from 2009 to 2013 was estimated using the method presented by World Health organization. Some epidemiological characteristics of pedestrians' fatalities were analyzed by SPSS. Results: Although YLL among 1000 male pedestrians decreased from 2.5 in 2009 to 1.5 in 2013, it increased from 0.9 to 2.1 among 1000 females during the same period. Higher proportion of death was found in female, illiterate, and married pedestrians {p 〈 0.001 ). In addition, mortality was higher in pedestrians living the cities, during daytime, at home, and in hospitals (p 〈 0.001 ). Conclusion: Consistent with the global trends, burden of pedestrian accidents in Fats was also excep- tionally high. Considering the national and cultural aspects of different countries, improving the safety of pedestrians demands a multi-dimensional approach with interventional factors concerning policies, rules, pedestrians, motor vehicles and environmental conditions taken into consideration.展开更多
