Cyber Range

We present a conceptual foundation and empirical framework for modeling cognitive complexity in cyber range event operating environments. Definitions of key concepts, such as cognitive complexity, task difficulty, and Blue Team cognitive workload, are informed by the literature of human factor engineering. This is followed by an approach to assessing cognitive complexity as experienced by a Blue Team in a given cyber range event operating environment, and a validation of that assessment method.

Visual Displays

An approach for measuring the cognitive complexity of visual display formats is presented. The approach involves modeling both the knowledge that can be extracted from a format and the knowledge an operator brings to a task. A semantic network formalism is developed to capture task-relevant knowledge, from which four orthogonal predictor measures of cognitive complexity are derived. In an experiment, seven different avionic missions, performed with the aid of a horizontal situation display, were studied, and three of the predictor measures were found to correlate significantly with observed task difficulty. The results indicate that a semantic network formalism can be used to produce an objective metric of format quality in terms of cognitive complexity.

Ultimate Objective

Amidst the macroeconomic, social, and industrial trends altering the industrial operating environment, calls have been made to shift attention from specialized but narrow technical content of engineering education to a broader competence base that better accommodates societal demands. This chapter focuses on the micro-level ethical conduct that materializes in face-to-face interaction in engineering teams. The chapter serves three aims: first, it defines the key concepts employed in the discussion. Second, it offers an account of the worth and impacts of investments in emotive skills in the engineering world. Finally, it describes a pedagogic experiment in incorporating ethics into engineering degree studies at Aalto University, Finland. The ultimate objective is to propose a teaching practice that would turn the currently marginal attempts to include ethical topics in engineers' syllabi into a mainstream mindset and philosophy that dictates decisions and drives conduct in future engineering communities.

A growing volume of literature proclaims the benefits of e-commerce for construction organizations in developing countries. However, it is questionable on what are determinants of a successful implementation of e-commerce in such a context. Furthermore, lacking a model or a method through which to discuss and assist for construction companies in improving their success rate of the implementation. This paper proposed such a method called the “integrated” e-commerce readiness method (IECR). In this method, the role of an organization’s perception of operating environment is highlighted, and e-readiness of an individual organization is considered as an integrated power of the internal and external resources.

Design Considerations

The existing design of ultrasound real-time scanners is not satisfactory from the standpoint of operator comfort or efficient use. As currently configured, these units are cumbersome and fatiguing to use and require unnecessarily complex and time-consuming movements on the part of the operator. Redesigning ultrasound scanners so that they conform to accepted principles of ergonomics or human-factor engineering should make it possible to achieve increased efficiency and improved study quality.

Review Criterion

The reviewing of operating experience at nuclear power plants (NPP) is not only critically important to safe and reliable operations, but also useful to guide the design of new plants which are similar to the current one under review. How to identify and analyze the safety-related operating experience and then implement a more extensive review is a vital and challengeable issue. In this paper, a methodology of human factor engineering (HFE) operating experience review (OER) is proposed for NPP. The need for the application of HFE in the life cycle activities of NPP and other nuclear facilities has been demonstrated by plant operating histories and regulatory and industry reviews. As a very important element of HFE, the OER is performed from the beginning of the design process. The main purpose of performing an OER is to verify that the applicant has identified and analyzed HFE-related safety problems and issues in previous designs that are similar to the current one. In this way, negative features associated with predecessor designs may be avoided in the current NPP design while retaining positive features. The research of OER concentrates on the aspect of review criterion, scope and implementation procedure of the HFE-related operating experience. As the NRC requirement, the scope of operating experience can be divided into six types in accordance with sources of information. The implementation procedures of USA and China are introduced, respectively. The resolution of HFE OER issues involve function allocation, changes in automation, HSI equipment design, procedures, training, and so forth. The OER conclusions can contribute to other HFE activities and improve the safety, reliability and usability of the HSI design in NPP.

Attribution Training

Perceived control over school performances is often assessed by means of attributions of performance to "controllable" or "non-controllable" causes. We assume that this assessment method is not reliable, because it is not possible to make a general distinction between controllable and non-controllable causes. Both developmental level and experience influence the perceived controllability of the causes. Also external attributions may be perceived as controllable. Our hypotheses are: (1) that children frequently perceive failures caused by "lack of competence", "task difficulty", and "insufficient explanation by the teacher" as controllable; and (2) that children with problems in learning and concentration perceive failures caused by "effort" as non-improvable more often than control children. Both hypotheses are confirmed. This implies that assessing perceived control by assessing attributions for school performances is not a reliable method. In addition, attribution-training should not focus merely on increasing the rate of attributions to "controllable" causes, but also on the translation of these "controllable" attributions to concrete behaviour.

The hydraulic steel structure is an important device in water resources and hydropower engineering, affected by operating environment, corrosion is becoming an important factor in affecting the structure on safe operation .In this paper, fuzzy assessment method for disaster degree identification is introduced, using the Monte-Carle numerical simulation for distance measurement to achieve the distance measurement calculated of corrosion morphology, making corrosion assessment of hydraulic steel gate quantitative. Combining with the study for attenuation of mechanical properties of corrosion components, this paper propose the method of quantitative correction of corrosion components based on five levels, clearing the impact properties of corrosion components caused by corrosion morphology .
