BCPE Certification Requirements
Request application materials from the BCPE website's online store at www.bcpe.org, by phone at, or by sending a check US applicants who have demonstrated eligibility for the exam will be notified of the date and location of the next exam approx. 2 months before the test date.
Methods
The attributable proportion is the proportion by which the outcome rate among those exposed would be reduced if the exposure were eliminated. None of the musculoskeletal disorders discussed in this report are exclusively due to occupational exposures.
Results
Two facts suggest the strength of the association between work-related psychosocial factors and back pain. Of the nine types of work-related psychosocial risk factors, six had strong evidence for an association with back pain (low job satisfaction, monotonous work, poor social support at work, high perceived stress, perceived high job demands and perceived ability to return). to work), and three had moderate evidence (low control over work, emotionally demanding work and the perception that work can be dangerous).

Introduction
Any sudden introduction to a legal process can be a worrying, anxiety-inducing, error-prone and frustrating experience. The researcher may be asked to explain his findings either as an expert witness or as a consultant to a law firm.
Human Factors Testimony
The expert's statement took two full days to cover all the human factors that the opposing party believed were relevant to the accident. There must be sufficient stability and predictability so that the driver does not lose control of the vehicle and cause an accident situation.
Forensic Issues
Expert qualifications generally refer to the weight of the evidence presented, not its admissibility (Campbell, 2001; Goodstein, 2000). Either human input is modified by perceptions that the vehicle's lateral stability is approaching limits (requiring cautionary input) or has exceeded its limits (requiring corrective action for the uncontrolled vehicle).
Court Appearances
In the other case, the expert opinion was contested on the basis of the “possibility of causation”. The expert witness may observe the reactions and behavior of the jurors as the testimony is given.

Introduction
A cost-benefit model that ergonomists and others can use to support their economic arguments for good working conditions. Unfortunately, none of the articles in this special issue proposed a generic method that could be used by ergonomists and others who would like to implement ergonomic solutions. Cost-benefit analysis is one of the tools we can use to correct this imbalance.
Financial Modeling
Cost-benefit analysis models assume that the company will already comply with the law. A cost-benefit analysis allows the benefits of an ergonomic intervention to be quantified for that company, presenting the value of the intervention to the company's decision-makers. A cost-benefit analysis also provides a logical framework to assess the impact of an ergonomic intervention on all aspects of the business.
Cost-Benefit Analysis
When used judiciously, a cost-benefit analysis can be a powerful tool to put forward one's case for funding an ergonomics project. This particular cost-benefit analysis model can be used to answer a number of economic questions that follow. Because a cost-benefit analysis can be used for individual workers, it is suitable for determining the cost of rehabilitating an injured worker.
Applications
In the first case, the improved loading of the trucks and, in the second, the reduction in line interruptions. In any cost-benefit analysis, it is only necessary to include enough information to provide a reasonable estimate of the costs and benefits.

Objectives and Structure of the Article
Overview of Selected System Approaches
A study carried out in English coal mines forms the starting point for the development of the socio-technical systems approach (Trist and Bamforth, 1951). It includes the environment insofar as it is relevant to the stabilization of the system (Luhmann, 1971). The progress of the theory lies in the fact that structures are considered as variables.
Work System Approach as an Analytical Framework
The applicable rules of the work process (instructions about actions) are also referred to as work methods. System optimization tasks include, for example, the implementation of the CIP in a work system. According to the theory of social systems (Section 5.2.5), the setting of boundaries is rather done by the work system itself.
Systematic Design of Work Systems
The information effort of the working people can be reduced with the help of work equipment such as templates or devices. General strategies for the work system design, apart from this systematic, sequential procedure, can be further differentiated and described in the following. It is further criticized that sequential concepts usually begin with the technological work system design and the following decisions are subordinated to the chosen technological concept (technological determinism).
Approaches to Anticipatory Work System Design
Development of a model for the coupling of the thermal regularization system and the cardiovascular system. The recovery time increases to the power of the energetic load value and the effective temperature. It illustrates the structure of the company and the products, which are relevant to the PPC.

Introduction: TQM and Human Factors Programs in Industry
Predictive control allows the process to operate with minimal setup time after a product changeover, facilitating steps towards just-in-time production. At the same time as these strategically driven quality changes have been taking place, there have been concurrent programs at other levels. Corporate responses to this have included injury/safety reduction programs (Rahimi, 1995), ergonomics programs (Liker, Joseph, and Armstrong, 1984) aimed at reducing employee injury, and similar impact reduction programs of human error (e.g. Taylor, 1990). ).
Fundamentals: The Basic Tenets of TQM and Human Factors
Table 6.2 is proposed as a working list, preserving the structure of the equivalent TQM list to facilitate comparison. As Table 6.2 clearly shows, ergonomics is a people-centered process, where detailed knowledge of human functioning is used as the basis for designing high-quality, safe systems. Optimize the job through equipment, environment and procedure design before optimizing the operator through selection, placement, motivation and training.
Applications of TQM and Ergonomics to Each Other
A plant-wide posture survey showed a significant improvement over the course of the project. Standard quality techniques should be used to measure process parameters, and models of human performance and well-being should be used to measure and understand the operator's role in the system. Think at the strategic level. Understand forces beyond the factory process, such as end-customer demands and active supply chain management.

Primer: The Need for User-Centered Design (UCD)
In addition to the poor layout, there were several issues with actually reading the cards to count votes. Because the system's design was negligent in addressing these critical components, obstacles arose to the ultimate goal of electing a president. Good designs take into account the user(s), the organization, the environment and the technology at various points during the design and implementation process.
Introduction to UCD
UCD directs the focus of the design process on the role of users in human-machine interactions, and the resulting dynamics with work, environment and organization. Eason (1995) describes three main goals of UCD, which include: (1) translating articulated user/context/work needs into general product requirements and design specifications; (2) production of several design options; and (3) evaluating the degree to which design options meet requirements. Intuitively the quality of the information gathered (and the subsequent quality of the design) is a function of the time in the design process in which the user is involved and the extent of their involvement.
Common Tools and Techniques for UCD
This clarification of the work system is important because it is the focus of UCD. This process FIGURE 7.3 The process of translating an understanding of the work system into design. It is this intimate knowledge of the work system that helps drive ergonomic design.
Conclusions
The challenge for evaluators, designers and developers is how to best match the evaluation method to the identified goals of the design within the organizational constraints of funding, lead time and availability of evaluators. As discussed, within the realm of UCD there are countless variations of techniques and tools to include end users and their needs in the design process, to generate data and knowledge of the work system, and to test and validate the usability, applicability, and applicability. evaluate. of system design alternatives. Users and the various aspects of the work system must be deliberately and judiciously woven into the design process to produce a useful, useful and attractive design.

Relation between Safety and Technical Risk
Evaluation of Technical Risk
Products of this pipe mill are pipes with diameters from 500 to 1420 mm. FIGURE 8.1 Gearboxes are single- or two-stage types with helical gears and with a synchronous motor. The analysis of maintenance costs and technical risk shows that the main area of interest is ultrasonic welding 1 . Therefore, it is very useful to carry out the technical risk analysis for all components of this ultrasonic welding machine 1 (figure 8.5).
Complex Method of Risk Evaluation in the Workplace
It is recommended that this technical risk assessment is always performed by the same person/team to reduce the human subjectivity factor. If this is not determined exactly, it limits the value for the acceptance of the technical risk. The main source of technical risk in this part of metallurgical technology is the improper handling of the liquid metal.
Application of Risk Management in Maintenance
There is a representation of one selected material flow in the steel mill, shown in Figure 8.6. After determining all necessary values, we obtain the final result: risk values for each element participating in the work process in the chosen segment of metallurgical technology.
