Air Transportation And Safety - Abstract
NASA Langley researchers addressed the Commercial Aviation Safety Team Safety Enhancement 211 through a series of studies to address "Attention-related Human Performance Limiting States" which include channelized attention, diverted attention, startle/surprise, and confirmation bias. The present report focuses on the development of improved training scenarios for operationally realistic Line-Oriented Flight Training scenarios. Areas addressed in the report include: (1) Highlights of events in the LOFT scenario used; (2) Interesting findings with implications for simulator motion; (3) Eye-tracking heat maps in proximity to failure events; (4) Researcher observations of crews as test subjects versus a pilot and a research team co-pilot; and (5) The results of a follow-up questionnaire completed by pilot participants regarding their usual training as well as the scenarios employed in the SHARP studies. These pilot ratings and comments are of value to simulation training developers.

Man/System Technology And Life Support - Abstract
In an era of increasing automation, it is important to design displays and input devices that minimize human error. In this context, information concerning the human response to the detection of incongruous information is important. Such incongruous information can be operationalized as unexpected (perhaps erroneous) information on which a decision by the human or operation by an automated system is based. In the aviation environment, decision making when faced with inadequate, incomplete, or incongruous information may occur in a failure scenario. An additional challenge facing the human operator in automated environments is maintaining alertness or vigilance. The vigilance issue is of particular concern as a factor that may interact with performance when faced with inadequate, incomplete, or incongruous information. From the literature on eye-scan behavior we know that the time spent looking at a particular display or indicator is a function of the type of information one is trying to discern from the display. For example, quick glances are all it takes for confirming that an indicator is in a normal position or range, whereas a continuous look of several seconds may be required for confirmation that a complex control input is having the desired effect. Important to consider is that while an extended look takes place, visual input from other sources may be missed. Much like an extended look, the interpretation of incongruous information may require extra time. The present experiment was designed to explore the performance consequences of a decision making task when incongruous information was presented. For this experiment a display incongruity was created on a subset of trials of a clock reading laboratory task. Display incongruity was made possible through presentation of 'impossible' times (e.g. 1:65 or 11:90). Subjects made 'same' 'different' decisions and keyboard responses to pairings of Analog-Analog (AA), Digital-Digital (DD), and Analog- Digital (AD), display combinations. For trials during which display incongruities were not presented, based on prior research comparing digital and analog clock displays, it would be expected that the Digital-Digital condition would result in the shortest response times and the Analog-Analog and Analog-Digital conditions would have longer response times. The performance consequence expected on trials with incongruous times would be very long response times.

CYBERTERRORISM ,DENIAL of service attacks ,AIR conditioning - Abstract
The future of warfare will likely not be won by those with merely the greatest military might. Rather, the world powers of the 21st Century will be those states that have the most robust cyber defensive capabilities coupled with an experimenting culture that allows them to develop the most effective offensive cyber weapons. Arguably the greatest challenge any state faces when coming up with an arsenal of powerful cyberattack capabilities is properly defining what its offensive cyber operations (OCO) will encompass. This research tackles the complexities of this problem by examining the attributes most necessary for effective OCO. Through the review of literature on cyber operations and on real-world cyberattacks that have already taken place, this paper defines five factors which OCO must consider in order to be truly effective: degree of damage inflicted, target specificity, undetectability, surprise, and degree that the attack can be prevented. This research employs systems engineering tools and techniques to prioritize how the US can focus on OCO for the 21st Century and beyond so that it is prepared to fight and win in its future wars.

On a near-daily basis, the news media informs the public of the latest company to succumb to the onslaught of a cyberattack and having its sensitive data records breached. Although considerable research has been conducted to improve cybersecurity from the perspective of bolstering defenses as one would do to fortify castles in the Middle Ages, this report analyzes whether or not a strategy of deterrence can be employed to bolster cyber defense. Drawing heavily from the defensive paradigm that resulted from the nuclear deterrence strategy of the 20th Century, this paper investigates how the US can achieve a more long-term equilibrium solution for cyberspace through a number of key principles inherent within deterrence. In doing so, this paper posits that cyber deterrence can be an effective strategy for US defense in the 21st Century. By employing a systems thinking approach to this complex problem, this research argues that there are 3 key attributes that help create effective cyber deterrence: improving international partnerships, diversifying both cyber and non-cyber weapons capabilities, and promoting the correct international narrative on cyber violations. This research finds that an effective cyber deterrence bolsters cybersecurity by dis-incentivizing threats and adversaries from perpetrating cyberattacks. [ABSTRACT FROM AUTHOR]

As threats continue to evolve within cyberspace, defense of the cyber domain requires that the most qualified and technically skilled individuals be able to help protect this increasingly important area in national security. The US Army defends the cyber domain against adversaries along multiple fronts--doing this effectively in cyberspace requires that the military develop a plan to leverage the talents and capabilities of individuals in the private sector to form an effective civilian cyber reserve force. To successfully integrate this cyber reserve force, the US And must take into consideration 3 critical concerns: the employment of effective security controls, the cultivation of key cyber skills, and the implementation of a cost-effective program that efficiently and effectively allows private sector cybersecurity professionals to serve in the Army Reserves. This research employs both qualitative and quantitative systems engineering models that help prioritize key stakeholder values and shape recommendations for future consideration. The goal of this research is to equip the US Army with a framework that can successfully integrate and implement a civilian reserve cyber force that is prepared for 21st Century warfare in cyberspace.

Objective: This work introduced judgment-based measures of spatial awareness and used them to evaluate terrain textures and fields of view (FOVs) in synthetic vision system (SVS) displays.Background: SVSs are cockpit technologies that depict computer-generated views of terrain surrounding an aircraft. In the assessment of textures and FOVs for SVSs, no studies have directly measured the three levels of spatial awareness with respect to terrain: identification of terrain, its relative spatial location, and its relative temporal location.Methods: Eighteen pilots made four judgments (relative azimuth angle, distance, height, and abeam time) regarding the location of terrain points displayed in 112 noninteractive 5-s simulations of an SVS head-down display. There were two between-subject variables (texture order and FOV order) and five within-subject variables (texture, FOV, and the terrain point's relative azimuth angle, distance, and height).Results: Texture produced significant main and interaction effects for the magnitude of error in the relative angle, distance, height, and abeam time judgments. FOV interaction effects were significant for the directional magnitude of error in the relative distance, height, and abeam time judgments.Conclusion: Spatial awareness was best facilitated by the elevation fishnet (EF), photo fishnet (PF), and photo elevation fishnet (PEF) textures.Application: This study supports the recommendation that the EF, PF, and PEF textures be further evaluated in future SVS experiments. Additionally, the judgment-based spatial awareness measures used in this experiment could be used to evaluate other display parameters and depth cues in SVSs. [ABSTRACT FROM AUTHOR]- Published

AERONAUTICAL safety measures , *COMMERCIAL aeronautics , *INFORMATION display systems - Abstract
The retrofit question concerns whether useful and effective synthetic vision displays are usable in aircraft that have limited-size-day spaces. Two experiments were conducted to examine the efficacy of these displays and develop field-of-view and terrain texture recommendations for design. The first experiment examined issues of field of view and display size using an Asheville, North Carolina, synthetic vision database and fixed-based simulator. The second experiment was conducted on the NASA B-757 aircraft at Dallas/Fort Worth International Airport and investigated the efficacy of both head-down and head-up displays and generic and photorealistic terrain texture. Both experiment confirmed the retrofit capability and that all sizes and texturing methods were found to be viable candidates for synthetic vision displays. These results, future directions, and implications for meeting national aeronautic safety and capacity goals are discussed. [ABSTRACT FROM AUTHOR]

METAL formability , *SHEET metal - Abstract
Testing of sheet metal formability has been a long-standing challenge because variability in test procedures and testing machines can mask material variations. In spite of the importance of such testing for manufacturing, few standards exist. The Ohio State University formability test (OSUFT) has shown promising improvements in scatter and speed compared with the limiting dome height (LDH) test, but few laboratory-to-laboratory scatter data have been available. The scatter in formability testing was investigated using several testing protocols with three ferritic stainless steel alloys: Type 409, Type 439, and a new 18Cr–Cb alloy. The sensitivity of the OSUFT results to punch speed, lubrication, specimen width, hold-down force, and sheet thickness was measured and procedures were defined to maximize the test effectiveness. Tensile and OSUFT testing were carried out independently at three laboratories using more than 45 coils of material. Laboratory-to-laboratory scatter of 0.4–2.2% of measured formability is less than that for tensile testing and much less than that reported for LDH testing. The scatter among laboratories for the OSUFT is approximately equal to test-to-test scatter at one laboratory. Coil-to-coil variations are typically greater than the observed test-to-test scatter, particularly in the transverse direction. [Copyright &y& Elsevier]

18. Oculometric Indices of Simulator and Aircraft Motion

Comstock Jr., James Raymond
- Abstract
In a series of three experiments on the effects on eye-scan behavior of both simulator and aircraft motion, the sensitivity of an oculometric measure to motion effects was demonstrated. "Fixation Time", defined as the time the eyes spend at a particular location before moving on (saccade) to another fixation point, was found to be sensitive to motion effects in each of the experiments conducted. The first experiment studied differences between simulator motion and no-motion conditions during a series of simulated Instrument Landing System (ILS) approaches. The mean fixation time for the no-motion condition was found to be significantly longer than for the motion condition for the five pilots tested. This was true particularly for the Flight Director, the instrument supplying attitude and deviation from glideslope information. A second experiment investigated eye-scan parameters based on data collected in flight, with the oculometer in the NASA Transport Systems Research Vehicle (TSRV), and in the fixed base TSRV simulator. The results of this study were similar to those of the first study, and showed fixation time and rate measures to be sensitive to motion (flight) and no-motion. Motion effects were most evident when the subject was viewing a display supplying attitude and flight path information. A third study addressed the question of the nature of the information provided by motion. Utilizing a part-task (monitoring one instrument), with motion in only one dimension (pitch) ten subjects were tested in no-motion, correct motion, and reversed direction motion conditions. The mean fixation times for the no motion condition were significantly longer than for either motion condition, while the two motion conditions did not differ significantly. The results of the present series of experiments support the hypothesis that motion serves an altering function, providing a "cue" or "clue" to the pilot that "something happened". The results do not support the hypothesis that direction of motion is conveyed through this type of motion information. The results suggest that simulation without motion cues may represent an understatement of the true capacity of the pilot.

- Abstract
The report presents the results of an experimental study in which aluminized and non-aluminized composite solid propellants were ignited under different environmental conditions. Ignition was achieved by radiative, convective and chemical heating. An optical system operating in two narrow wavelength bands was used to detect the onset of ignition on and near the surface of the propellant. It was found that ignition delay time was dependent on the wavelength used for detection, the method of heating, and other environmental factors. The implications of these results are discussed in relation to existing ignition theories, and recommendations are made for further study.

- Abstract
Hyper-IgE syndromes (HIES) are a heterogeneous group of rare primary immunodeficiency diseases classically characterized by the triad of atopic dermatitis, and recurrent cutaneous and pulmonary infections. Autosomal dominant, loss-of-function STAT3 pathogenic variants are the most common genetic cause, which lead to deficiency of Th17 lymphocytes, impaired interferon gamma production, and IL-10 signal transduction, and an unbalanced IL-4 state. Dupilumab, a monoclonal antibody to the IL-4a receptor, inhibits both IL-4 and IL-13, and has been shown to improve atopic dermatitis and other manifestations of HIES including asthma and allergic bronchopulmonary aspergillosis. We present a pediatric patient with HIES who presented predominantly with eosinophilic folliculitis, recurrent cutaneous infections, and other non-eczematous findings and achieved sustained clearance with dupilumab., (© 2022 The Authors.

- Abstract
Importance: Dermatologists with specialty training in pediatric dermatology are scarce, which can mean extended wait times and reduced access to care for patients. Lower compensation for pediatric dermatology visits compared with adult visits may affect physician career choice and contribute to workforce shortages., Objective: To evaluate differences in work relative value units (wRVUs) generated by pediatric and adult outpatient dermatology encounters., Design, Setting, and Participants: This cross-sectional study used data from outpatient dermatology encounters at a single-site academic center in Atlanta, Georgia, from September 1, 2016, to March 31, 2020. Encounters with patients younger than 18 years were classified as pediatric, and encounters with those 18 years or older were classified as adult. Encounters with missing data were excluded as were those generating 0 wRVUs, inpatient visits, nursing visits, postoperative encounters, cosmetic procedures, phototherapy visits, and Mohs surgery encounters., Main Outcomes and Measures: Work relative value units generated per encounter type were assessed through multivariable linear regression models adjusted for the potential confounder of sex., Results: The study included 12 989 pediatric dermatology encounters (mean [SD] age, 7.3 [5.2] years; 7586 [58.4%] girls) and 78 057 adult dermatology encounters (mean [SD] age, 54.9 [18.9] years; 45 724 [58.6%] women). Pediatric encounters were associated with 0.23 (95% CI, 0.21-0.25; P < .001) fewer wRVUs than adult encounters after adjusting for sex. In a mediation analysis, biopsies and destruction of premalignant lesions explained 74.1% (95% CI, 69.6%-77.9%; P < .001) of the wRVU difference between pediatric and adult encounters., Conclusions and Relevance: This cross-sectional study found significant differences in wRVUs generated between adult and pediatric dermatology encounters that were largely attributable to biopsies and destruction of premalignant lesions. Policies that increase the value of cognitive services to be on par with procedural care may mitigate wRVU differences and improve reimbursement for pediatric dermatologists.

- Abstract
Background: Consumers seek "clean" and "natural" products based on their perception of safety. However, there is no standard, scientific basis, or regulatory oversight in the marketing or ingredient use for "clean" products., Objective: The aim of this study was to determine the prevalence of allergenic ingredients in "clean" products., Methods: Target and Walgreens Web sites were queried for "clean" products with inclusion of 1470 products. Ingredient lists were analyzed for potential allergens. Analysis included descriptive statistics and χ2 test., Results: The most common allergens were fragrances/botanicals (1218/1470, 82.9%), phenoxyethanol (591/1470, 40.2%), tocopherol (545/1470, 40.2%), benzoic acid and benzoates (434/1470, 29.5%), propylene glycol (369/1470, 25.1%), alkyl glucosides (305/1470, 20.7%), ethylhexylglycerin (304/1470, 20.7%), cetyl alcohol (282/1470, 19.2%), cocamidopropyl betaine (258/1470, 17.6%), and benzyl alcohol (232/1470, 15.8%). Among fragrances/botanicals, the most common ingredients found were fragrance/perfume/aroma (911/1470, 68.2%), citrus derivatives (375/1470, 25.5%), linalool (305/1470, 20.7%), limonene (279/1470, 19.0%), and benzyl alcohol (231/1470, 15.7%). A total of 93.8% of the products (1379/1470) contained at least 1 potential allergen., Conclusions: Most "clean" products contain a potential allergen, predominately fragrances and botanicals., Competing Interests: M.R. is the American Contact Dermatitis Society Contact Allergy Management Program Director.

- Abstract
Lipoatrophic panniculitis (LP) is a rare childhood panniculitis characterized by sclerotic, atrophic plaques on the extremities. We present a case of LP diagnosed during the inflammatory phase that was difficult to distinguish clinically from eosinophilic fasciitis. This report adds to the limited phenotypic spectrum of LP by differentiating the clinical features of disease activity from disease damage and highlighting the importance of biopsy in establishing a diagnosis., (© 2020 Wiley Periodicals, Inc.)

- Abstract
Background: Patients with allergic contact dermatitis rely on ingredient lists published in databases and by online retailers to find safe skincare products., Objective: The aim of this study was to determine the accuracy of product ingredient labeling by comparing drugstore product labels to ingredient lists published online., Methods: Amazon was queried for best-selling items in several categories of skincare, generating a list of 93 products. These products were then found at a local Target and Walgreens and online on Contact Allergen Management Program, SkinSAFE, and Consumer Product Information Database. Drugstore product labels were compared with online ingredient lists and analyzed for discrepancies., Results: There were 31 occurrences in which an allergen listed in the 2017 American Contact Dermatitis Society Core Allergen Series was omitted (present on the in-store label but missing from an online list.) Seven omissions occurred on Contact Allergen Management Program, 11 occurred on SkinSAFE, 5 occurred on Consumer Product Information Database, and 8 occurred on Amazon., Conclusions: Definitive treatment of allergic contact dermatitis is avoidance of allergens found on patch testing. These data suggest that patients may be at risk of inadvertent exposure to allergens from products, which are supposedly deemed safe according to online ingredient lists.
