我国部分保健与安全活动经济代价的初步评价

社会中的许多卫生保健活动都需要在经济代价和人的安全健康之间作出权衡。这种权衡往往需要确定危害人们健康和安全的经济价值。笔者从人力资本和支付意愿两个方面,对我国卫生、环保、安全有关的经济数据进行了评价分析。在人力资本方面,考虑了人均终生的国民生产总值、国民收入、消费水平、职工工资、城乡居民收入。在支付意愿方面,考虑了医疗救治的费用、社会保险费用、司法赔偿、职业劳动保护费用、降低辐射危害的费用以及政府采用数值等。根据这些分析评价,笔者建议：我国卫生保健有关的人的社会经济价值,若以１９９０ 年可比价格计算,分布在（９～４０）万元之间,适中的估计为２０ 万元。     

The Relationship Between Workers’ Safety Culture and Accidents,Near Accidents and Health Problems

One of the dimensions treated as part of a company’s safety culture or climate is workers’ attitudes towards risk and safety. In the present study these personal aspects are defined as workers’ safety culture, which is understood as a way of acting focused on life and taking care of one’s health. A questionnaire on safety culture was filled out by 200 employees of a metallurgical enterprise. Factor analysis was used to determine empirical scales of the questionnaire, whereas variance analysis was used to test hypotheses. The results confirmed the hypotheses that people who experienced accidents, dangerous situations, and—to a lesser extent—health problems had a lower level of safety culture. Nevertheless not all of the scales determined during factor analysis turned out to be significant as far as all kinds of those undesirable situations are concerned. Proposals for future studies are formulated in the conclusion.     

When bathing leads to drowning in older adults

Introduction: Bathing is the most problematic activity of daily living for aging adults, and the ability to perform it is influenced by physical capabilities that decrease with age. Drowning is an under-documented event related to bathing for older adults. This study investigates the circumstances of these tragedies, to prevent them. Methods: Census of 2005–2014 bathtub drownings in the province of Quebec (Canada) involving victims aged 65 +. Coroner's reports were analyzed using a grid based on factors previously associated with bath-related drownings in literature, iteratively modified. Results: Among the 92 bathtub drowning victims inventoried, 42% were aged 65 +. The average age of older victims is 79 (65–97, ± 9 years). Main probable cause of drowning is a cardiac problem, although only 19% of victims had a medical history of heart disease. Most victims were alone in their apartment or residence when drowning occurred. Risky periods appear to be springtime, Sundays, and evenings. Despite expectations, relevant information about the physical environment is very scarce. Conclusions: At least 39 Quebecers, aged 65 +, drowned in their bathtubs over a 10-year period. More older adults than children are victims of bathtub drownings in community-dwellings. It seems that bathing may induce heart distress, leading to an appreciable number of drownings. Practical implications: Since cardiac health problems are present in these deplorable events, promoting access to safety devices in the environment (emergency button, grab bars) and modified personal hygiene habits (bathing chair, showering) might be potential ways to prevent drowning and improve safety in older adults while they perform their personal hygiene, an essential activity for health and human dignity.     

Target level of safety for Chinese airspace

This article considers the target level of safety (TLS) for Chinese airspace. If collision risk is lower than TLS, we can say the separation minima meet the safety requirements, so the TLS is the safety limit on the flight operation. But there are no regulations on TLS in China by now, hence, it is necessary to judge whether it is fair to apply the TLS proposed by ICAO to evaluating air traffic safety in China.The accidents data of more than 50 years are collected, and we apply the trend extrapolation to predicting the safety level in the future so as to resolve the TLS problem. The resulted showed the safety level in the period from 2010 to 2020 is very close to TLS established by ICAO. The results show the safety level of collision risk in China has reached the international level and it is rational to use TLS of ICAO to assess collision risk.

An integrated framework of safety performance evaluation for oil and gas production plants: Application to a petroleum transportation station

Safety performance evaluation is a significant way to ensure the safety of oil and gas production plants. Various evaluation methods have been proposed to make safety evaluation more consistent and scientific. However, a major concern is that many existing safety evaluation measurements are still subjective and are not easy to obtain in a uniform way, which can be attributed to the challenges that process plants faced such as people having different knowledge levels, equipment with dispersed locations and management with many processes. This paper aims to display the impact of risk factors on system safety level in a succinct and visual way that may be expected to overcome subjective opinions from experts and provide a more pertinent and practical safety strategies. To this end, an integrated framework is developed, which considers crucial risk factors from pipeline, static equipment, dynamic equipment and management. First, Fault tree analysis (FTA) is used to explicitly determine the crucial r risk factors. Then, a novel fuzzy cognitive map cooperating with relative degree analysis model (FCM-RDA) is proposed to deal with the weigh distribution opinions. Finally, considering the oil and gas production process is a complex system, a fuzzy comprehensive evaluation (FCE) is employed to calculate the overall safety level.

A new-generation safety contest in the construction industry – A long-term evaluation of a real-life intervention

A new-generation safety campaign has been taking place in southern Finland since 1997. The Finnish Construction Employer’s Association together with trade unions, safety inspectorates, and other institutions have been organising a safety contest based on the standardised TR-observation method. Safety inspectors conduct evaluation visits without previous notice to the sites, and best performing companies and sites are rewarded at annually held public seminars. Even though participation is voluntary, more than 70% of the total number of construction sites in the target area have participated in the contest, and the results have been successful. Deficiencies in protection against falling have decreased by 63%, in order and tidiness by 69%, and in working habits by 51%. The effectiveness is also evident in the accident figures. An estimated 4000 accidents and three fatalities are prevented each year, while other parts of the country during the same period show no improvement in accident risk. A key success factor may be the adoption among firms of a new, standardised safety monitoring method which has been used effectively by senior management teams. The method employs a combination of penalties and incentives in order to set and enforce new safety targets. Another success factor is the close co-operation between the construction industry, labour organisations and safety authorities.

When workplace safety depends on behavior change: Topics for behavioral safety research

Introduction

Comprehensive interventions that address public-health concerns invariably include behavior-change strategies. In occupational safety and health, behavioral safety is an approach designed to improve safety performance directly through peer observations of safe behaviors, goal setting, performance feedback, and celebrations or incentives for reaching safety goals. Although the basic components of behavioral safety processes have been studied and widely documented, the current safety literature reveals several gaps in knowledge. These gaps are associated mostly with wide practice variations among the common process elements and uncertainty about the influence of organizational and other external factors.

Impact to Industry

A major objective of this paper was to highlight not only key topic areas that warrant further research, but also to propose a list of research questions that are tied to uncertainties about various intervention practices. If only a portion of these topic areas and research questions are addressed through systematic reviews, field interventions, surveys, and laboratory-based studies, then the knowledge gained will significantly improve the delivery and effectiveness of behavioral safety interventions and thus their impact on worker health and safety.     

What the research says about concussion risk factors and prevention strategies for youth sports: A scoping review of six commonly played sports

Introduction: Given the growing research on potential adverse outcomes related to concussion and other serious brain injuries and the increased susceptibility for concussion among youth athletes, primary prevention is vital to protect the health and safety of this population. The purpose of this study is to summarize the current research on risk factors and primary concussion prevention strategies focused on specific youth sports, and to identify research gaps. Methods: A literature search was conducted using six electronic databases. A scoping review method was used to identify studies that addressed risk factors or primary concussion prevention strategies focused on youth athletes (ages 5–18 years) in six sports (football, ice hockey, soccer, lacrosse, basketball, and wrestling). Results: Of the 18 publications identified, the publications focused on risk factors (N = 11), policy (N = 1), rule changes (N = 3), education (N = 2), equipment (N = 2), and playing technique (N = 0). Some articles had information related to multiple topics. Conclusions: Current research on concussion prevention has primarily been focused on risk factors. There are a dearth of studies that examine primary concussion prevention in sports. When studies do exist, most focus on football and ice hockey. Only a small number of studies focus solely on risk factors or primary prevention in soccer, lacrosse, basketball, and wrestling—all sports in which concussions are common. Practical applications: This scoping review summarizes current research on concussion risk factors and primary prevention strategies in specific sports focused on youth athletes and identifies research gaps to help inform future efforts.

Safe driving practices and factors associated with motor-vehicle collisions among people with insulin-treated diabetes mellitus: Results from the Diabetes and Driving (DAD) study

IntroductionThe aim of this study was to assess the prevalence of people with insulin-treated diabetes mellitus (ITDM) who have discussed issues related to diabetes and driving with their health care providers (HCPs). We also sought to determine the safe driving practices that are currently employed by this group. Finally, we investigated the factors that might increase the risk of motor-vehicle collisions (MVCs) among this group in Saudi Arabia.MethodThis cross-sectional study surveyed a representative sample of 429 current male drivers with ITDM using a structured questionnaire in Saudi Arabia.ResultsMost of the participants (76.5%) never discussed topics regarding diabetes and driving with their HCPs. The majority of the participants (61.8%) reported at least never doing one of the following: (a) carrying a blood glucose testing kit while driving, (b) testing their blood glucose level before driving or during a journey, or (c) having thought of a specific threshold of blood glucose level that would preclude driving. Three factors were associated with a higher risk of MVCs among participants with ITDM: (a) being on a basal/boluses regimen, (b) never having a discussion regarding diabetes and driving with their HCPs, and (c) having experienced hypoglycemia during driving.ConclusionsThe majority of people with ITDM had not had a discussion regarding diabetes and driving with their HCPs, which was reflected by a lack of safe driving practices. People with ITDM should be encouraged to take precautions while driving in order to prevent future MVCs.Practical applicationsThis research highlights the importance of investing more effort in educating drivers who have diabetes about safe driving practices by their health care providers. Also, it will attracts the attention of policymakers for an urgent need to establish clear policies and procedures for dealing with drivers who have diabetes.     

Determinants of safety priorities in transport – The effect of personality,worry, optimism,attitudes and willingness to pay

Much research within risk has investigated risk perception and how risk behaviour is understood by the public. One goal of risk research is to understand how people perceive and interpret risk to facilitate safe behaviour. This is seen as important for many different reasons, one being because policy measures might be more effective when they address and understand individual differences in beliefs and perceptions of a target group (Steg, L., Sievers, I., 2000. Cultural theory and individual perceptions of environmental risks. Environment and Behavior 32 (2), 250–269). The main aim of this study was to investigate what is most important in regard to safety priorities. Three personality assets – anxiety, excitement-seeking and trust – were first examined. Further factors were driver optimism, worrying about transport risks, willingness to pay to increase safety, and negative attitudes toward traffic rules (as a driver). The results are based upon two questionnaire surveys carried out among a representative sample of the Norwegian public in 2004. The results showed that worry was the most important predictor of safety priorities. In addition, negative attitudes towards rules were also found to have an impact on priority. The proposed model explained 44% of the variance of safety priority. This knowledge gives additional information to improve the success of interventions because it will develop the ability to target those who consider safety to be of low priority and guide them to modify their attitudes. This may in turn increase their value of safety.     

A qualitative investigation of factors affecting school district administrators’ decision to adopt a national young worker curriculum

Introduction: Even though the majority of youth in the U.S. work, and workers under the age of 18 are seriously injured on the job at higher rates when compared to adults, most adolescents lack instruction on workplace safety and health. Method: This qualitative study examines the extent to which selected U.S. school districts provide workplace safety and health instruction to students and explores the factors that influence districts’ decision to adopt a free, foundational occupational safety and health (OSH) curriculum. Results: Results from key informant interviews conducted with a purposive sample of 34 school administrators revealed that only a third of the districts have at least 75% of their students receive some instruction on workplace safety and health, while 15% indicated they provide no instruction on this topic. District staff who indicated that they provide OSH instruction stated that it is most often taught through career and technical education (CTE; 65%) and/or health classes (26%). They believed the benefits of providing this instruction include assisting students to get jobs (38%) and helping students learn about safety (32%), while competing demands (44%) and time constraints (41%) were identified as barriers to providing OSH education to students. Conclusions: Given the importance of work to teens and their increased risk of work injury, interested stakeholders—including parents, teachers, employers, and the public health community—should promote the inclusion of workplace safety and health instruction in U.S. secondary schools. Practical Applications: This research fills a gap in current knowledge about the extent to which OSH is currently taught within U.S. secondary schools, enumerates barriers and facilitators to the inclusion of workplace safety and health instruction in schools, presents a free, foundational curriculum in workplace safety and health, and provides directions for future research on the vital role schools can play in preparing the future workforce for safe and healthy employment.     

Occupational Health and Social Resources

There is a relationship between the changes in work-related diseases and the following factors: the transformation of the organization of work, organizational development, as well as human and social changes in the work environment. These factors also influence the maintenance of industrial health and safety standards at work. Safety technology will continue to be important, but will be reduced in significance compared to the so-called soft factors, that is, all dimensions and parameters affecting people’s health and social environment at the work place.

It seems that in the future the relationship between the social resource development and work protection will become more relevant. Social resource development influences the quality of work performance and motivation, the quality of work and work protection, the likelihood of accidents and breakdowns, and the level of self-control and capacity of change.

The consequences of work protection research will be discussed in this article with a focus on the contribution of social sciences.

灰色层次分析法在航空工业企业事故中的分析运用

航空工业常使用高精度、高价值的关键仪器、设备、设施,各种型号飞机试验、试飞频繁。机械伤害、高处坠落、冲压设备伤手等事故时有发生。分析航空企业事故致因主要为事故预防措施不到位,生产工艺设备安全性不高,职业病预防及管理不到位。利用数学建模的思路,引入灰色层次分析法(GAHP),以航空某企业为例,将评估对象安全状况分为指标层、准层次、目标层,逐级计算灰数,确定所属灰类,得出航空某企业的安全综合评估结果。评估结果显示,GAHP法能够客观反映航空企业安全状况,值得在航空企业安全生产事故风险评估中推广使用。     

工作安全分析在管理实践中的应用

管理者有责任确保员工的健康和安全,包括告之员工工作场所存在的危险,提供必要的设备以确保健康和安全,并建立适当的健康和安全规程。因此,管理者有义务在员工开展工作之前评估健康和安全风险,进一步完善消除或减轻这些风险。而工作安全分析job safety analysis（JSA）,就是提供了这样一种方法,是一种常用于评估与作业有关的基本风险分析工具,以确保风险得以有效的控制。JSA一般在控制房或作业现场进行。对于大型或复杂的任务,初始的JSA可以作在办公室以桌面练习的形式进行。其实施关键是JSA应由熟悉现场作业和设备的、有经验的人员进行。JSA分析方法的优点就是把工作中潜在危害的关键活动或重要步骤作为分析对象,发挥集体的智慧,采用定量的方法把风险描述出来,从而进一步实施风险预防和控制,同时又和现场作业票证管理相结合,在现场的实际工作中取得了良好的效果。
