    2012-04-01

    There is an increasing interest in human factors within the healthcare environment reflecting the understanding of their impact on safety. The aim of this paper is to explore how human factors might be taught on resuscitation courses, and improve course outcomes in terms of improved mortality and morbidity for patients. The delivery of human factors training is important and this review explores the work that has been delivered already and areas for future research and teaching. Medline was searched using MESH terms Resuscitation as a Major concept and Patient or Leadership as core terms. The abstracts were read and 25 full length articles reviewed. Critical incident reporting has shown four recurring problems: lack of organisation at an arrest, lack of equipment, non functioning equipment, and obstructions preventing good care. Of these, the first relates directly to the concept of human factors. Team dynamics for both team membership and leadership, management of stress, conflict and the role of debriefing are highlighted. Possible strategies for teaching them are discussed. Four strategies for improving human factors training are discussed: team dynamics (including team membership and leadership behaviour), the influence of stress, debriefing, and conflict within teams. This review illustrates how human factor training might be integrated further into life support training without jeopardising the core content and lengthening the courses.

    2008-01-01

    As the "passion that animates authentic professionalism," humanism must be infused into medical education and clinical care as a central feature of medicine's professionalism movement. In this article, we discuss a current definition of humanism in medicine. We will also provide detailed descriptions of educational programs intended to promote humanism at a number of medical schools in the United States (and beyond) and identify the key factors that make these programs effective. Common elements of programs that effectively teach humanism include: (1) opportunities for students to gain perspective in the lives of patients; (2) structured time for reflection on those experiences; and (3) focused mentoring to ensure that these events convert to positive, formative learning experiences. By describing educational experiences that both promote and sustain humanism in doctors, we hope to stimulate the thinking of other medical educators and to disseminate the impact of these innovative educational programs to help the profession meet its obligation to provide the public with humanistic physicians.

    Clinical governance (CG) is an approach to quality improvement in healthcare aimed at achieving a patient-centered health care system. The main objective of this study was to highlight human centered healthcare latent factors underlying the results of a CG assessment performed in the teaching hospital "A. Gemelli" of Rome, Italy. CG implementation levels were assessed through OPTIGOV© (OPTimizing healthcare GOVernance), a CG scorecard methodology. In order to identify the variables generating latent factors that can influence the governance of the Hospital, the multiple correspondence analysis (MCA) was applied. The application of OPTIGOV© showed a good CG implementation level in the Gemelli Hospital. By applying MCA, the variables aggregated so as to define 3 latent factors (F1: assessment for people oriented improvement strategy; F2: assessment for people targeted management; F3: tracking for timely accountable people) explaining as a whole 82.68% of the total variance and respectively 48.09% (F1), 24.95% (F2) and 9.64% (F3). The heuristic interpretation of the three latent factors could bring back to the concept of humanization in healthcare. This study shows that in the teaching hospital "A. Gemelli" humanization in healthcare is the driver of health care quality improvement.

    China has approximately one-fifth of the world's population. Despite the recent success in controlling major parasitic diseases, parasitic diseases remain a significant human health problem in China. Hence, the discipline of human parasitology is considered as a core subject for undergraduate and postgraduate students of the medical sciences. We consider the teaching of human parasitology to be fundamental to the training of medical students, to the continued research on parasitic diseases, and to the prevention and control of human parasitic diseases. Here, we have summarized the distribution of educational institutions in China, particularly those that teach parasitology. In addition, we have described some existing parasitology courses in detail as well as the teaching methods used for different types of medical students. Finally, we have discussed the current problems in and reforms to human parasitology education. Our study indicates that 304 regular higher education institutions in China offer medical or related education. More than 70 universities have an independent department of parasitology that offers approximately 10 different parasitology courses. In addition, six universities in China have established excellence-building courses in human parasitology.

    Even under optimal conditions, helicopter flight is a most demanding form of human-machine interaction, imposing continuous manual, visual, communications, and mental demands on pilots. It is made even more challenging by small margins for error created by the close proximity of terrain in NOE flight and missions flown at night and in low visibility. Although technology advances have satisfied some current and proposed requirements, hardware solutions alone are not sufficient to ensure acceptable system performance and pilot workload. However, human factors data needed to improve the design and use of helicopters lag behind advances in sensor, display, and control technology. Thus, it is difficult for designers to consider human capabilities and limitations when making design decisions. This results in costly accidents, design mistakes, unrealistic mission requirements, excessive training costs, and challenge human adaptability. NASA, in collaboration with DOD, industry, and academia, has initiated a program of research to develop scientific data bases and design principles to improve the pilot/vehicle interface, optimize training time and cost, and maintain pilot workload and system performance at an acceptable level. Work performed at Ames, and by other research laboratories, will be reviewed to summarize the most critical helicopter human factors problems and the results of research that has been performed to: (1) Quantify/model pilots use of visual cues for vehicle control; (2) Improve pilots' performance with helmet displays of thermal imagery and night vision goggles for situation awareness and vehicle control; (3) Model the processes by which pilots encode maps and compare them to the visual scene to develop perceptually and cognitively compatible electronic map formats; (4) Evaluate the use of spatially localized auditory displays for geographical orientation, target localization, radio frequency separation; (5) Develop and flight test control

    Future space missions will be significantly longer than current shuttle missions and new systems will be more complex than current systems. Increasing communication delays between crews and Earth-based support means that astronauts need to be prepared to handle the unexpected on their own. As crews become more autonomous, their potential span of control and required expertise must grow to match their autonomy. It is not possible to train for every eventuality ahead of time on the ground, or to maintain trained skills across long intervals of disuse. To adequately prepare NASA personnel for these challenges, new training approaches, methodologies, and tools are required. This research project aims at developing these training capabilities. By researching established training principles, examining future needs, and by using current practices in space flight training as test beds, both in Flight Controller and Crew Medical domains, this research project is mitigating program risks and generating templates and requirements to meet future training needs. Training efforts in Fiscal Year 09 (FY09) strongly focused on crew medical training, but also began exploring how Space Flight Resource Management training for Mission Operations Directorate (MOD) Flight Controllers could be integrated with systems training for optimal Mission Control Center (MCC) operations. The Training Task addresses Program risks that lie at the intersection of the following three risks identified by the Project: 1) Risk associated with poor task design; 2) Risk of error due to inadequate information; and 3) Risk associated with reduced safety and efficiency due to poor human factors design.

    Cerdà and Civera (2012); Fernández Raga et al., (2013) and Cerdà et al., (2014) show that teaching Earth Sciences to students older than 55 is a new challenge for the universities of developed countries due to the higher life expectancy and the arrival of new students and teaching programs to the academy. Fire, due to the background of many of our students, is one of those topics that need more attention when teaching to students older than 55. Most of them see the fire as the enemy and not as a part of the natural and human ecosystems. The view of the scientists is based in the scientific method, and they see the fire as part of the ecosystems and the human societies (Roebroeks and Villa, 2011; Archibald et al., 2012; Berna et al, 2012; Romme et al., 2012; Zumbrunnen et al., 2012). Moreover, the studies developed on the soils, vegetation and hydrological response of fire affected land, show that the fire disturbance use to be short and the ecosystems return to the pre-fire period after a window of disturbance (Cerdà and Lasanta, 2005; Doerr and Cerdà, 2005; Lasanta and Cerdà, 2005; Granjed et al., 2011; Pérez Cabello et al., 2012; Bodí et al., 2013; Guenon et al., 2013; León et al., 2013: Pereira et al., 2013; Pereira et al., 2015; Prats et al., 2015), and this is related to the policies applied in different countries (Carreiras et al., 2014). More recent advances in the impact of fire on soils can be found in Bento-Gonçalves et al. (2012) This research show the different strategies that we apply to explain the students older than 55 to understand the natural processes that are involved in nature due to the fire. The lectures are developed at the lectures room as an introduction about the fire in the Earth System and how the fire modify the soils, the water resources and change the vegetation cover, and 10 hours of field work in an recently fire affected land. The second part of the course, 10 hours in the field, will be done in February during a visit

    2016-01-01

    Objective This study tests the reliability of a system (FINANS) to collect and analyze incident reports in the financial trading domain and is guided by a human factors taxonomy used to describe error in the trading domain. Background Research indicates the utility of applying human factors theory to understand error in finance, yet empirical research is lacking. We report on the development of the first system for capturing and analyzing human factors–related issues in operational trading incidents. Method In the first study, 20 incidents are analyzed by an expert user group against a referent standard to establish the reliability of FINANS. In the second study, 750 incidents are analyzed using distribution, mean, pathway, and associative analysis to describe the data. Results Kappa scores indicate that categories within FINANS can be reliably used to identify and extract data on human factors–related problems underlying trading incidents. Approximately 1% of trades (n = 750) lead to an incident. Slip/lapse (61%), situation awareness (51%), and teamwork (40%) were found to be the most common problems underlying incidents. For the most serious incidents, problems in situation awareness and teamwork were most common. Conclusion We show that (a) experts in the trading domain can reliably and accurately code human factors in incidents, (b) 1% of trades incur error, and (c) poor teamwork skills and situation awareness underpin the most critical incidents. Application This research provides data crucial for ameliorating risk within financial trading organizations, with implications for regulation and policy. PMID:27142394

    The exploration of space is one of the most fascinating domains to study from a human factors perspective. Like other complex work domains such as aviation (Pritchett and Kim, 2008), air traffic management (Durso and Manning, 2008), health care (Morrow, North, and Wickens, 2006), homeland security (Cooke and Winner, 2008), and vehicle control (Lee, 2006), space exploration is a large-scale sociotechnical work domain characterized by complexity, dynamism, uncertainty, and risk in real-time operational contexts (Perrow, 1999; Woods et ai, 1994). Nearly the entire gamut of human factors issues - for example, human-automation interaction (Sheridan and Parasuraman, 2006), telerobotics, display and control design (Smith, Bennett, and Stone, 2006), usability, anthropometry (Chaffin, 2008), biomechanics (Marras and Radwin, 2006), safety engineering, emergency operations, maintenance human factors, situation awareness (Tenney and Pew, 2006), crew resource management (Salas et aI., 2006), methods for cognitive work analysis (Bisantz and Roth, 2008) and the like -- are applicable to astronauts, mission control, operational medicine, Space Shuttle manufacturing and assembly operations, and space suit designers as they are in other work domains (e.g., Bloomberg, 2003; Bos et al, 2006; Brooks and Ince, 1992; Casler and Cook, 1999; Jones, 1994; McCurdy et ai, 2006; Neerincx et aI., 2006; Olofinboba and Dorneich, 2005; Patterson, Watts-Perotti and Woods, 1999; Patterson and Woods, 2001; Seagull et ai, 2007; Sierhuis, Clancey and Sims, 2002). The human exploration of space also has unique challenges of particular interest to human factors research and practice. This chapter provides an overview of those issues and reports on sorne of the latest research results as well as the latest challenges still facing the field.

    For a long time,Chinese EFL teaching has been following the teacher-centered model,which emphasizes the cognitive aspect but ignores the affective factors. So "emotional illiteracy" is a common phemenon and harmful to language learning and students' all-round development. This essay lays special stress on humanistic approach and analyzes the influence of some important affective factors on language learning,for the purpose of inviting teachers' attention to students' emotions in fulfilling their teaching task.

    The general human factors analysis analyzes human functions, effects and influence in a system. But in a narrow sense, it analyzes human influence upon the reliability of a system, it includes traditional human reliability analysis, human error analysis, man-machine interface analysis, human character analysis, and others. A software development project in software engineering is successful or not to be completely determined by human factors. In this paper, we discuss the human factors intensions, declare the importance of human factors analysis for software engineering by listed some instances. At last, we probe preliminarily into the mentality that a practitioner in software engineering should possess.

    Parasitic infection profile in China has been changed greatly with the rapid economic development in China since the 1980s, such as the tremendous decreased infection rate of the soil-borne helminthiasis, the elimination of filariasis, the control of malaria, and the initiation to eradicate malaria in 2020. Some food-borne parasitic infections have increased such as Clonorchiasis, Cysticercosis, and Echinococcosis, probably because of the increased chances of eating out. This trend directly affected the status of Human Parasitology teaching in medical universities, such as the shorten length of this course, re-adjusted contents structure and teaching manners, even the change of the name of this course. In this paper, we analyzed the current status and challenges of Human Parasitology teaching in medical universities, and discussed the requisite contents and manners in course delivery and measures to improve the quality of Human Parasitology teaching in China.

    An effective integration of human abilities and limitations is crucial to the success of all NASA missions. The Integrated Human Factors Toolkit facilitates this integration by assisting system designers and analysts to select the human factors tools that are most appropriate for the needs of each project. The HF Toolkit contains information about a broad variety of human factors tools addressing human requirements in the physical, information processing and human reliability domains. Analysis of each tool includes consideration of the most appropriate design stage, the amount of expertise in human factors that is required, the amount of experience with the tool and the target job tasks that are needed, and other factors that are critical for successful use of the tool. The benefits of the Toolkit include improved safety, reliability and effectiveness of NASA systems throughout the agency. This report outlines the initial stages of development for the Integrated Human Factors Toolkit.

    1995-03-01

    As industries position themselves for the competitive markets of today, and the increasingly competitive global markets of the 21st century, agility, or the ability to rapidly develop and produce new products, represents a common trend. Agility manifests itself in many different forms, with the agile manufacturing paradigm proposed by the Iacocca Institute offering a generally accepted, long-term vision. In its many forms, common elements of agility or agile manufacturing include: changes in business, engineering and production practices, seamless information flow from design through production, integration of computer and information technologies into all facets of the product development and production process, application of communications technologies to enable collaborative work between geographically dispersed product development team members and introduction of flexible automation of production processes. Industry has rarely experienced as dramatic an infusion of new technologies or as extensive a change in culture and work practices. Human factors will not only play a vital role in accomplishing the technical and social objectives of agile manufacturing. but has an opportunity to participate in shaping the evolution of industry paradigms for the 21st century.

    The majority of errors, litigation, and complaints in the health service are due to 'human factors', yet the term is still not widely understood and is sometimes used interchangeably to refer to team training or communication skills. Although including these, the subject of 'human factors' goes far beyond this to look at systems, environmental influences, and interactions with equipment, in addition to self-awareness and human interaction. All of these aspects are captured inHuman Factors in Healthcare and are built into a new framework: the SHEEP model, which breaks down into five key areas:

  11. How to learn about teaching: An evolutionary framework for the study of teaching behavior in humans and other animals.

    Science.gov (United States)

    Kline, Michelle Ann

    2015-01-01

    The human species is more reliant on cultural adaptation than any other species, but it is unclear how observational learning can give rise to the faithful transmission of cultural adaptations. One possibility is that teaching facilitates accurate social transmission by narrowing the range of inferences that learners make. However, there is wide disagreement about how to define teaching, and how to interpret the empirical evidence for teaching across cultures and species. In this article I argue that disputes about the nature and prevalence of teaching across human societies and nonhuman animals are based on a number of deep-rooted theoretical differences between fields, as well as on important differences in how teaching is defined. To reconcile these disparate bodies of research, I review the three major approaches to the study of teaching - mentalistic, culture-based, and functionalist - and outline the research questions about teaching that each addresses. I then argue for a new, integrated framework that differentiates between teaching types according to the specific adaptive problems that each type solves, and apply this framework to restructure current empirical evidence on teaching in humans and nonhuman animals. This integrative framework generates novel insights, with broad implications for the study of the evolution of teaching, including the roles of cognitive constraints and cooperative dilemmas in how and when teaching evolves. Finally, I propose an explanation for why some types of teaching are uniquely human, and discuss new directions for research motivated by this framework.

    Objectives To understand whether aviation-derived human factors training is acceptable and useful to healthcare professionals. To understand whether and how healthcare professionals have been able to implement human factors approaches to patient safety in their own area of clinical practice. Methods Qualitative, longitudinal study using semi-structured interviews and focus groups, of a multiprofessional group of UK NHS staff (from the emergency department and operating theatres) who have received aviation-derived human factors training. Results The human factors training was evaluated positively, and thought to be both acceptable and relevant to practice. However, the staff found it harder to implement what they had learned in their own clinical areas, and this was principally attributed to features of the informal organisational cultures. Conclusions In order to successfully apply human factors approaches in hospital, careful consideration needs to be given to the local context and informal culture of clinical practice. PMID:24631959

  1. The concept of lifestyle factors, based on the teaching of avicenna (ibn sina).

    Science.gov (United States)

    Choopani, Rasool; Emtiazy, Majid

    2015-01-01

    According to the definition stated in the beginning of the "Al-Qanun fi al-Tibb" (the Qanun of Medicine); medicine is a science, from which one learns the states of the human body; health and disease and what causes them, in order to preserve good health when it exists, and restore it when it is lacking. Based on this issue, Avicenna believes that medical science belongs to all human without any limitation, and maintenance of health is one of its prime objectives. He states that many disorders are related to errors in the 6 factors, which are essential for maintaining health and preventing diseases. Avicenna described these six essential factors (lifestyle factors) in his masterpiece, Qanun of Medicine, as "Asbab-e-Settah-e-Zaruriah." Based on the teaching of Avicenna, the first step for maintaining health and approaches to treatment is modification of lifestyle factors, including of nutrition, physical activity, etc.

  2. Accepting, understanding, teaching, and learning (human) evolution: Obstacles and opportunities.

    Science.gov (United States)

    Pobiner, Briana

    2016-01-01

    Questions about our origin as a species are universal and compelling. Evolution-and in particular human evolution-is a subject that generates intense interest across the world, evidenced by the fact that fossil and DNA discoveries grace the covers of major science journals and magazines as well as other popular print and online media. However, virtually all national polls indicate that the majority of Americans strongly reject biological evolution as a fact-based, well-tested, and robust understanding of the history of life. In the popular mind, no topic in all of science is more contentious or polarizing than evolution and media sources often only serve to magnify this polarization by covering challenges to the teaching of evolution. In the realm of teaching, debates about evolution have shaped textbooks, curricula, standards, and policy. Challenges to accepting and understanding evolution include mistrust and denial of science, cognitive obstacles and misconceptions, language and terminology, and a religious worldview, among others. Teachers, who are on the front lines of these challenges, must be armed with the tools and techniques to teach evolution in formal education settings across grades K-16 in a straightforward, thorough, and sensitive way. Despite the potentially controversial topic of human evolution, growing research is demonstrating that a pedagogical focus on human examples is an effective and engaging way to teach core concepts of evolutionary biology.

  3. Human factors in safety and business management.

    2010-02-01

    Human factors in safety is concerned with all those factors that influence people and their behaviour in safety-critical situations. In aviation these are, for example, environmental factors in the cockpit, organisational factors such as shift work, human characteristics such as ability and motivation of staff. Careful consideration of human factors is necessary to improve health and safety at work by optimising the interaction of humans with their technical and social (team, supervisor) work environment. This provides considerable benefits for business by increasing efficiency and by preventing incidents/accidents. The aim of this paper is to suggest management tools for this purpose. Management tools such as balanced scorecards (BSC) are widespread instruments and also well known in aviation organisations. Only a few aviation organisations utilise management tools for human factors although they are the most important conditions in the safety management systems of aviation organisations. One reason for this is that human factors are difficult to measure and therefore also difficult to manage. Studies in other domains, such as workplace health promotion, indicate that BSC-based tools are useful for human factor management. Their mission is to develop a set of indicators that are sensitive to organisational performance and help identify driving forces as well as bottlenecks. Another tool presented in this paper is the Human Resources Performance Model (HPM). HPM facilitates the integrative assessment of human factors programmes on the basis of a systematic performance analysis of the whole system. Cause-effect relationships between system elements are defined in process models in a first step and validated empirically in a second step. Thus, a specific representation of the performance processes is developed, which ranges from individual behaviour to system performance. HPM is more analytic than BSC-based tools because HPM also asks why a certain factor is

    This consensus group from the 2017 Academic Emergency Medicine Consensus Conference "Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes" held in Orlando, Florida on May 16, 2017 focused on the use of human factors and simulation in the field of emergency medicine. The human factors discipline is often underutilized within emergency medicine but has significant potential in improving the interface between technologies and individuals in the field. The discussion explored the domain of human factors, its benefits in medicine, how simulation can be a catalyst for human factors work in emergency medicine, and how emergency medicine can collaborate with human factors professionals to affect change. Implementing human factors in emergency medicine through healthcare simulation will require a demonstration of clinical and safety outcomes, advocacy to stakeholders and administrators, and establishment of structured collaborations between human factors professionals and emergency medicine, such as in this breakout group.

    Ergonomics/human factors is, above anything else, a systems discipline and profession, applying a systems philosophy and systems approaches. Many things are labelled as system in today's world, and this paper specifies just what attributes and notions define ergonomics/human factors in systems terms. These are obviously a systems focus, but also concern for context, acknowledgement of interactions and complexity, a holistic approach, recognition of emergence and embedding of the professional effort involved within organization system. These six notions are illustrated with examples from a large body of work on rail human factors.

    Selecting measures is a necessary component of human factors research. Proper selection must take into account the representation problem (how is the assignment of numbers to objects or phenomena justified?) and the uniqueness problem (to what degree is this assignment unique?). Other key human factors measurement issues include subject representativeness, variable representativeness, and setting representativeness. It is difficult to create a single measure that captures essential characteristics of complex systems. Several examples illustrate how theory can guide measurement selection in such diverse human factors research as vigilance, turning off warning alarms, information requirements for military command centers, subjective workload, heart-rate signal analysis, and heat stress in nuclear power plants.

  8. Study on Angiogenesis Factor of Human Osteosarcoma

    Angiogenesis factor of human osteosarcoma was partially purified and its biological features were studied. The active peptide with 8000 to 10 000 u molecular weight in the conditioned medium obtained from the cultivation of human osteosarcoma cells were partially purified by ultrafiltration, chromatography and dialysis. The angiogenic effects of the fractions were assessed by proliferation assay of human umbilical vein and pig aorta thoracic endothelial cells. The results showed that the chromatography fractions of 4 to 6 could significantly promote the proliferation of the endothelial cells. It was suggested that the human osteosarcoma cells could synthesize and secrete angiogenesis factor with a molecular weight of 8000 to 10 000 u.

    2015-10-01

    Full Text Available This article explores how I teach about human rights and so-called humanitarian interventions to MA and Ph.D. students.  The course has three main themes or foci.  First, what are human rights and why have the social and economic human rights laid out in the Universal Declaration of Human Rights been so neglected or rejected, especially by the U.S.  Second, how has American foreign policy used and abused human rights.  Third, why have liberal or humanitarian interventions of a militarized sort become so prevalent since the end of the Cold War and why are they so damaging.  The goal is to get students to look critically at the meaning and uses of human rights, about which many display a naive enthusiasm.

    Wisdom is a complex phenomenon: it finds its home primarily but not exclusively in theology, philosophy, psychology, education--that is, in the humanities--and in life itself. In a paradoxical manner, wisdom finds its home in the world of the unanswerable, where there are no empirical proofs and no obvious answers. Wisdom actually finds its place…

    Full Text Available The concept of holiness is one of the key theological issues. Semantically the term “holiness” focuses on God, theonly absolutely Holy, who lives and works in the Church, and is also the source of the holiness of the Church. Visiblereflection of the holiness of the Church on earth are the countless saints – people who are called by God to be holy, andwith the proper spiritual life, had grown up in perfection and become able to accept the special sanctification by the Holy Spirit. But God is calling to be holy not only those who have tasted holiness – which formally announced to the world bythe church in an act of canonization – but all Christians.The term “holy” is used by Bible not only in reference to God, but also to the people, places and things, sanctified bycontact with God, exalted by him, dedicated to the service of God. The article deals on the holiness of the human in theOld and New Testaments only.The New Testament repeats call to be holy directed by God to man in the Old Testament (cf. 1 Peter 1:15. But at thesame time God calls the human to be perfect (Mathew 5:48. The source of human holiness in the New Testament is JesusChrist, who received it from God the Father. The New Testament sacrifice of Jesus Christ replaced the Old Testamentsacrifice rendered by archpriest. This sacrifice is the source of human sanctification and forgiveness of sins (Hebrews10:14. Christ sacrifice has opened the way for every man to God, and this path is not limited neither by time nor byspace.The New Testament reveals the concept of human holiness much wider and deeper than the Old Testament did. On thepages of Gospels and Epistles of the Apostles there are shown the human patterns that make up the definition of holiness.Then they are repeated and explained in the Church by Holy Fathers mainly. It is thanks to the action of the Holy Trinityevery Christian can be saint. It is thanks to the adoption by the Son of God the human nature, members

    Key problem areas in the management and transfer of information in the National Airspace System, contributing to human errors are identified. Information-management aspects supporting the user's ability to assess prevailing situations accurately with adequate time to make an informed decision are considered. The relationship between judgment biases and requirements for managing weather information is illustrated by examining such hazardous weather phenomena as microbursts and windshears. The system of air-ground communication relying almost exclusively on voice transmissions is discussed, and recommendations in the areas of communications procedures and technology development are provided.

    Five hundred students attending higher education institutions in northeastern Brazil responded to questionnaires about their anatomy classes; students represented a variety of different health sciences disciplines. Analysis of the responses revealed the participation of teaching assistants in a large percentage of classes and the use of teaching resources, particularly images, from conventional radiographs to magnetic resonance images. The number of classes for cadaver dissection and the number of students with access to that type of class were small. In most cases, dissection was performed according to anatomic regions or systems. Medicine and nursing students had the highest number of practical dissection classes. Most students were assessed using practical and theoretical tests. Findings revealed conditions similar to those found elsewhere. Resources should be renewed and used to improve teaching for students whose courses demand the study of human anatomy.

    2015-01-01

    We developed and offered a sequence of neuroscience courses geared toward changing the way non-science students interact with the sciences. Although we accepted students from all majors and at all class levels, our target population was first and second year students who were majoring in the fine arts or the humanities, or who had not yet declared a major. Our goal was to engage these students in science in general and neuroscience in particular by teaching science in a way that was accessible and relevant to their intellectual experiences. Our methodology was to teach scientific principles through the humanities by using course material that is at the intersection of the sciences and the humanities and by changing the classroom experience for both faculty and students. Examples of our course materials included the works of Oliver Sacks, V.S. Ramachandran, Martha Nussbaum, Virginia Woolf and Karl Popper, among others. To change the classroom experience we used a model of team-teaching, which required the simultaneous presence of two faculty members in the classroom for all classes. We changed the structure of the classroom experience from the traditional authority model to a model in which inquiry, debate, and intellectual responsibility were central. We wanted the students to have an appreciation of science not only as an endeavor guided by evidence and experimentation, but also a public discourse driven by creativity and controversy. The courses attracted a significant number of humanities and fine arts students, many of whom had already completed their basic science requirement.

    Cohen, Marc M.; Brody, Adam R.

    1991-01-01

    Developments in research on space human factors are reviewed in the context of a self-sustaining interstellar spacecraft based on the notion of traveling space settlements. Assumptions about interstellar travel are set forth addressing costs, mission durations, and the need for multigenerational space colonies. The model of human motivation by Maslow (1970) is examined and directly related to the design of space habitat architecture. Human-factors technology issues encompass the human-machine interface, crew selection and training, and the development of spaceship infrastructure during transtellar flight. A scenario for feasible instellar travel is based on a speed of 0.5c, a timeframe of about 100 yr, and an expandable multigenerational crew of about 100 members. Crew training is identified as a critical human-factors issue requiring the development of perceptual and cognitive aids such as expert systems and virtual reality.

    The objective of this study is to develop human factors engineering program review guidelines and alarm system review guidelines in order to resolve the two major technical issues: 25. Human Factors Engineering Program Review Model and 26. Review Criteria for Human Factors Aspects of Advanced Controls and Instrumentation, which are related to the development of human factors safety regulation guides being performed by KINS. For the development of human factors program review guidelines, we made a Korean version of NUREG-0711 and added our comments by considering Korean regulatory situation and reviewing the reference documents of NUREG-0711. We also computerized the Korean version of NUREG-0711, additional comments, and selected portion of the reference documents for the developer of safety regulation guides in KINS to see the contents comparatively at a glance and use them easily. For the development of alarm system review guidelines, we made a Korean version of NUREG/CR-6105, which was published by NRC in 1994 as a guideline document for the human factors review of alarm systems. Then we will update the guidelines by reviewing the literature related to alarm design published after 1994. (author). 12 refs., 5 figs., 2 tabs.

    Mining, by its very nature, requires workers and technology to function in an unpredictable environment that can not easily be engineered to accommodate human factors. Miners' physical and cognitive capabilities are sometimes stretched to the point that 'human error' in performance result. Mine safety researchers estimate that 50-85% of all mining injuries are due, in large part, to human error. Further research suggests that the primary causes of these errors in performance lie outside the individual and can be minimized by improvements in equipment design, work environments, work procedures and training. The human factors research is providing the science needed to determine which aspects of the mining environment can be made more worker-friendly and how miners can work more safely in environments that can not be improved. Underground mines have long been recognized as an innately hazardous and physically demanding work environment. Recently, mining is becoming a more complicated process as more sophisticated technologies are introduced. The more complicated or difficult the tasks to be performed, the more critical it is to have a systematic understanding of the humans, the technology, the environments, and how they interact. Human factors is a key component in solving most of today's mine safety and health problems. Human factors research primarily centered around solving problems in the following four areas: 1) How mining methods and equipment affect safety, 2) Evaluating the fit between miner's physical capabilities and the demands of their job, 3) Improving miner's ability to perceive and react to hazards, 4) Understanding how organizational and managerial variables influence safety. Human factor research was begun during the World war II. National Coal Board (British Coal) of Great Britain commenced ergonomics in 1969, and Bureau of Mine of United States started human factor researches in same year. Japan has very short history

    In the 21 st century,the medical model has transformed from the biological model to the biopsycho-social medical model. The transformation of medical model raises higher requirements for the training of medical staff. Comprehensive promotion of the reform of medical education has become the consensus and trend,which breeds the integrated medical teaching that is based on modules and organ systems. As one of eight integrated modules,the human body structure course of Shanghai Jiao Tong University School of Medicine introduces morphological structures of normal human organs according to function systems( such as locomotor system,digestive system,angiological system,and nervous system) of human organs and parts of human body. This course endeavors to integrate theories with practices,contents of disciplines of basic medicine,and basic medicine with clinical medicine. The human body structure course combines basic medicine with clinical medicine and is an important part of medical science.

  4. Factors influencing teaching style in block-scheduled science classrooms

    Science.gov (United States)

    Schoen Giddings, Linda

    This survey study sought to determine the extent to which teachers' personal belief systems, the leadership practices of the principal, and the nature of the organization as a professional learning community influence their teaching methodologies. The data were contributed by 172 South Carolina science teachers from 65 4 x 4 block-scheduled high schools. The teachers were pre-identified by teaching style as predominantly constructivist or traditional. The online survey consisted of two parts. Part I was the CTBA (Torff & Warburton 2005), which examined teacher beliefs regarding critical-thinking classroom strategies. Part II was the short form of the LOLSO Project Questionnaires (Shins et al., 2002), which examined teacher perceptions of their principal as a transformational leader and of their school as a learning organization. Logistic regression analysis identified two significant factors differentiating constructivist and traditional teachers. Traditional teachers were more likely to believe that low critical-thinking strategies were appropriate strategies for use in the classroom and constructivist teachers were more likely to perceive their schools as learning organizations. These two factors, when entered into the logistic regression predictive equation, could predict group membership with a 61% accuracy level. While not a differentiating factor, there was also a strong correlation between leadership and organizational learning (r = .86). These findings are consistent with other research that has found that schools which are learning organizations support more constructivist pedagogy and student-centered classrooms and are dependent upon strong support from school leadership.

    Objective: To investigate the effectiveness of a high-fidelity teaching simulation based on an NLN/Jef-fries simulation in the nursing education theoretical framework and its influencing factors. Methods: A high-fidelity teaching simulation on clinical nursing practices using intelligent human an-alogues was conducted with 200 students, and The Simulation Design Scale, and the Student Satisfaction and Self-Confidence in Learning Scale developed by the National League for Nursing were used to evaluate the training effectiveness and its influencing factors. Results: For the high-fidelity teaching simulation, students gave scores of 4.36 ± 0.54 points for satis-faction and 4.33 ± 0.46 points for Self-Confidence. The students highly rated the five dimensions of teaching design, i.e., teaching objectives/information, assistance/support for students, problem solving, guided feedback, and fidelity. The teaching design was closely correlated with the satisfaction of the high-fidelity teaching simulation and self-efficacy, and the dimensions of teaching objectives/informa-tion and assistance/support for students were particularly strong predictors of teaching effectiveness. Conclusions: A high-fidelity teaching simulation based on Jeffries' theoretical framework improved student satisfaction with the simulation and their Self-Confidence. In planning simulations, teachers should take into account five characteristics, i.e., teaching objectives/information on simulation educa-tion, assistance/support for students, problem solving, guided reflection, and fidelity, to achieve better teaching effectiveness.

    A model based on an input process and outcome conceptualisation is suggested to address safety-relevant factors in emergency medicine. As shown in other dynamic and demanding environments, human factors play a decisive role in attaining high quality service. Attitudes held by health-care providers, organisational shells and work-cultural parameters determine communication, conflict resolution and workload distribution within and between teams. These factors should be taken into account to improve outcomes such as operational integrity, job satisfaction and morale.

    Knight, Andrew

    2007-01-01

    Animal use resulting in harm or death has historically played an integral role in veterinary education, in disciplines such as surgery, physiology, biochemistry, anatomy, pharmacology, and parasitology. However, many non-harmful alternatives now exist, including computer simulations, high quality videos, ''ethically-sourced cadavers'' such as from animals euthanased for medical reasons, preserved specimens, models and surgical simulators, non-invasive self-experimentation, and supervised clinical experiences. Veterinary students seeking to use such methods often face strong opposition from faculty members, who usually cite concerns about their teaching efficacy. Consequently, studies of veterinary students were reviewed comparing learning outcomes generated by non-harmful teaching methods with those achieved by harmful animal use. Of eleven published from 1989 to 2006, nine assessed surgical training--historically the discipline involving greatest harmful animal use. 45.5% (5/11) demonstrated superior learning outcomes using more humane alternatives. Another 45.5% (5/11) demonstrated equivalent learning outcomes, and 9.1% (1/11) demonstrated inferior learning outcomes. Twenty one studies of non-veterinary students in related academic disciplines were also published from 1968 to 2004. 38.1% (8/21) demonstrated superior, 52.4% (11/21) demonstrated equivalent, and 9.5% (2/21) demonstrated inferior learning outcomes using humane alternatives. Twenty nine papers in which comparison with harmful animal use did not occur illustrated additional benefits of humane teaching methods in veterinary education, including: time and cost savings, enhanced potential for customisation and repeatability of the learning exercise, increased student confidence and satisfaction, increased compliance with animal use legislation, elimination of objections to the use of purpose-killed animals, and integration of clinical perspectives and ethics early in the curriculum.

    Full Text Available This study analyzes the system of relationships that may explain the impact of information technology (IT on competitive advantage. In this social and economic system, the study focuses on the human factors that play a key role in IT effectiveness. This is a first step to empirically specifying which human resources can complement the effect of IT on organizations. The paper revisits the main theoretical frameworks that can explain the research issue and proposes an empirical model to test the hypotheses. The results, obtained from a Data Envelopment Analysis, show that there are some human factors that positively affect the influence of IT utilization on competitive advantage. Nevertheless, other structural, industrial and internal factors may play an important role in the relationship.

    This paper summarizes the past and present successes of the Habitability and Human Factors Branch (HHFB) at NASA Johnson Space Center s Space Life Sciences Directorate (SLSD) in including the Human-As-A-System (HAAS) model in many NASA programs and what steps to be taken to integrate the Human-Centered Design Philosophy (HCDP) into NASA s Systems Engineering (SE) process. The HAAS model stresses systems are ultimately designed for the humans; the humans should therefore be considered as a system within the systems. Therefore, the model places strong emphasis on human factors engineering. Since 1987, the HHFB has been engaging with many major NASA programs with much success. The HHFB helped create the NASA Standard 3000 (a human factors engineering practice guide) and the Human Systems Integration Requirements document. These efforts resulted in the HAAS model being included in many NASA programs. As an example, the HAAS model has been successfully introduced into the programmatic and systems engineering structures of the International Space Station Program (ISSP). Success in the ISSP caused other NASA programs to recognize the importance of the HAAS concept. Also due to this success, the HHFB helped update NASA s Systems Engineering Handbook in December 2007 to include HAAS as a recommended practice. Nonetheless, the HAAS model has yet to become an integral part of the NASA SE process. Besides continuing in integrating HAAS into current and future NASA programs, the HHFB will investigate incorporating the Human-Centered Design Philosophy (HCDP) into the NASA SE Handbook. The HCDP goes further than the HAAS model by emphasizing a holistic and iterative human-centered systems design concept.

    Tuberculosis (TB) is a major threat to human health, especially in many developing countries. Human genetic variability has been recognised to be of great relevance in host responses to Mycobacterium tuberculosis infection and in regulating both the establishment and the progression of the disease. An increasing number of candidate gene and genome-wide association studies (GWAS) have focused on human genetic factors contributing to susceptibility or resistance to TB. To update previous reviews on human genetic factors in TB we searched the MEDLINE database and PubMed for articles from 1 January 2014 through 31 March 2017 and reviewed the role of human genetic variability in TB. Search terms applied in various combinations were 'tuberculosis', 'human genetics', 'candidate gene studies', 'genome-wide association studies' and 'Mycobacterium tuberculosis'. Articles in English retrieved and relevant references cited in these articles were reviewed. Abstracts and reports from meetings were also included. This review provides a recent summary of associations of polymorphisms of human genes with susceptibility/resistance to TB. © 2017 John Wiley & Sons Ltd.

    This study reports about teacher motivation and work engagement in a Dutch University Medical Centre (UMC). We examined factors affecting the motivation for teaching in a UMC, the engagement of UMC Utrecht teaching faculty in their work, and their engagement in teaching compared with engagement in patient care and research. Based on a pilot study within various departments at the UMCU, a survey on teaching motivation and work engagement was developed and sent to over 600 UMCU teachers. About 50 % responded. Work engagement was measured by the Utrecht Work Engagement Scale, included in this survey. From a list of 22 pre-defined items, 5 were marked as most motivating: teaching about my own speciality, noticeable appreciation for teaching by my direct superior, teaching small groups, feedback on my teaching performance, and freedom to determine what I teach. Feedback on my teaching performance showed the strongest predictive value for teaching engagement. Engagement scores were relatively favourable, but engagement with patient care was higher than with research and teaching. Task combinations appear to decrease teaching engagement. Our results match with self-determination theory and the job demands-resources model, and challenge the policy to combine teaching with research and patient care.

  2. The Foundations of Human Cooperation in Teaching and Imitation.

    Humans exhibit extensive large-scale cooperation, of a form unprecedented in the natural world. Here I suggest that this cooperation arises in our species alone because of our uniquely potent capacities for social learning, imitation and teaching, combined with the co-evolutionary feedbacks that these capabilities have generated on the human mind. Culture took human populations down evolutionary pathways not available to non-cultural species, either by creating conditions that promoted established cooperative mechanisms, such as indirect reciprocity and mutualism, or by generating novel cooperative mechanisms not seen in other taxa, such as cultural group selection. In the process, gene-culture co-evolution seemingly generated an evolved psychology, comprising an enhanced ability and motivation to learn, teach, communicate through language, imitate and emulate, as well as predispositions to docility, social tolerance, and the sharing of goals, intentions and attention. This evolved psychology is entirely different from that observed in any other animal, or that could have evolved through conventional selection on genes alone.

    When planning for control room upgrades, nuclear power plants have to deal with a multitude of engineering and operational impacts. This will inevitably include several human factors considerations, including physical ergonomics of workstations, viewing angles, lighting, seating, new communication requirements, and new concepts of operation. In helping nuclear power utilities to deal with these challenges, the Idaho National Laboratory (INL) has developed effective methods to manage the various phases of the upgrade life cycle. These methods focus on integrating human factors engineering processes with the plant’s systems engineering process, a large part of which is the development of end-state concepts for control room modernization. Such an end-state concept is a description of a set of required conditions that define the achievement of the plant’s objectives for the upgrade. Typically, the end-state concept describes the transition of a conventional control room, over time, to a facility that employs advanced digital automation technologies in a way that significantly improves system reliability, reduces human and control room-related hazards, reduces system and component obsolescence, and significantly improves operator performance. To make the various upgrade phases as concrete and as visible as possible, an end-state concept would include a set of visual representations of the control room before and after various upgrade phases to provide the context and a framework within which to consider the various options in the upgrade. This includes the various control systems, human-system interfaces to be replaced, and possible changes to operator workstations. This paper describes how this framework helps to ensure an integrated and cohesive outcome that is consistent with human factors engineering principles and also provide substantial improvement in operator performance. The paper further describes the application of this integrated approach in the

    As we know, the human brain is one of the most complicated organs in the human body, which is the key and difficult point in neuroanatomy and sectional anatomy teaching. With the rapid development and extensive application of imaging technology in clinical diagnosis, doctors are facing higher and higher requirement on their anatomy knowledge. Thus, to cultivate medical students to meet the needs of medical development today and to improve their ability to read and understand radiographic images have become urgent challenges for the medical teachers. In this context, we developed a digital interactive human brain atlas based on the Chinese visible human datasets for anatomy teaching (available for free download from http://www.chinesevisiblehuman.com/down/DHBA.rar). The atlas simultaneously provides views in all 3 primary planes of section. The main structures of the human brain have been anatomically labeled in all 3 views. It is potentially useful for anatomy browsing, user self-testing, and automatic student assessment. In a word, it is interactive, 3D, user friendly, and free of charge, which can provide a new, intuitive means for anatomy teaching.

    Full Text Available We are aware of a large number of marine accidents that result in numerous casualties and even deaths and substantial negative environmental effects. The objective of this paper is to indicate factors that contribute to human errors which is identified as the most frequent cause to marine accidents. Despite rapid technological development and safety legislation, this paper identifies the human factor as the waekest link in maritime safety system. This analysis could lead to decrease of vessel accidents. In addition, starting from the European Maritime Safety Agency data and by linear regression model application, we have obtained the trend of number of ships involved in marine accidents as well as the trend of lives lost in marine accidents  in and around European Union waters.

    The events which have led to the intensive study of aircraft structural problems have contributed in no less measure to the study of human factors which influence aircraft maintenance and inspection. Initial research emphasis on aging aircraft maintenance and inspection has since broadened to include all aircraft types. Technicians must be equally adept at repairing old and new aircraft. Their skills must include the ability to repair sheet metal and composite materials; control cable and fly-by-wire systems; round dials and glass cockpits. Their work performance is heavily influenced by others such as designers, technical writers, job card authors, schedulers, and trainers. This paper describes the activities concerning aircraft and maintenance human factors.

    Current human activities are seriously eroding the ability of natural and social systems to cope. Clearly we cannot continue along our current path without seriously damaging our own ability to survive as a species. This problem is usually framed as one of sustainability. As concerned professionals, citizens, and humans there is a strong collective will to address what we see as a failure to protect the natural and social environments that supports us. While acknowledging that we cannot do this alone, human factors and ergonomics needs to apply its relevant skills and knowledge to assist where it can in addressing the commonly identified problem areas. These problems include pollution, climate change, renewable energy, land transformation, and social unrest amongst numerous other emerging global problems. The issue of sustainability raises two fundamental questions for human factors and ergonomics: which system requires sustaining and what length of time is considered sustainable? In this paper we apply Wilson (2014) parent-sibling-child model to understanding what is required of an HFE sustainability response. This model is used to frame the papers that appear in this Special Issue.

  17. Space Station crew safety - Human factors model

    Science.gov (United States)

    Cohen, M. M.; Junge, M. K.

    1984-01-01

    A model of the various human factors issues and interactions that might affect crew safety is developed. The first step addressed systematically the central question: How is this Space Station different from all other spacecraft? A wide range of possible issue was identified and researched. Five major topics of human factors issues that interacted with crew safety resulted: Protocols, Critical Habitability, Work Related Issues, Crew Incapacitation and Personal Choice. Second, an interaction model was developed that would show some degree of cause and effect between objective environmental or operational conditions and the creation of potential safety hazards. The intermediary steps between these two extremes of causality were the effects on human performance and the results of degraded performance. The model contains three milestones: stressor, human performance (degraded) and safety hazard threshold. Between these milestones are two countermeasure intervention points. The first opportunity for intervention is the countermeasure against stress. If this countermeasure fails, performance degrades. The second opportunity for intervention is the countermeasure against error. If this second countermeasure fails, the threshold of a potential safety hazard may be crossed.

    1976-06-01

    The effect of human epidermal growth factor (hEGF), a 5,400 molecular weight polypeptide isolated from human urine, on the growth of human foreskin fibroblasts (HF cells) was studied by measuring cell numbers and the incorporation of labeled thymidine. The addition of hEGF to HF cells growing in a medium containing 10% calf serum resulted in a 4-fold increase in the final density. The presence of hEGF also promoted the growth of HF cells in media containing either 1% calf serum or 10% gamma globulin-free serum. The addition of hEGF to quiescent confluent monolayers of HF cells, maintained in a medium with 1% calf serum for 48 hours, resulted in a 10- to 20-fold increase in the amount of 3H-thymidine incorporation after 20-24 hours. The stimulation of thymidine incorporation was maximal at an hEGF concentration of 2 ng/ml, was dependent on the presence of serum, and was enhanced by the addition of ascorbic acid. In confluent cultures of HF cells, subject to density dependent inhibition of growth, hEGF was able to stimulate DNA synthesis more effectively than fresh calf serum. Human EGF stimulated DNA synthesis in quiescent cultures, however, regardless of cell density. The addition of rabbit anti-hEGF inhibited all effects of this growth factor on HF cells.

  20. Activated human neutrophils release hepatocyte growth factor/scatter factor.

    LENUS (Irish Health Repository)

    McCourt, M

    2012-02-03

    BACKGROUND: Hepatocyte growth factor or scatter factor (HGF\\/SF) is a pleiotropic cytokine that has potent angiogenic properties. We have previously demonstrated that neutrophils (PMN) are directly angiogenic by releasing vascular endothelial growth factor (VEGF). We hypothesized that the acute inflammatory response can stimulate PMN to release HGF. AIMS: To examine the effects of inflammatory mediators on PMN HGF release and the effect of recombinant human HGF (rhHGF) on PMN adhesion receptor expression and PMN VEGF release. METHODS: In the first experiment, PMN were isolated from healthy volunteers and stimulated with tumour necrosis factor-alpha (TNF-alpha), lipopolysaccharide (LPS), interleukin-8 (IL-8), and formyl methionyl-leucyl-phenylalanine (fMLP). Culture supernatants were assayed for HGF using ELISA. In the second experiment, PMN were lysed to measure total HGF release and HGF expression in the PMN was detected by Western immunoblotting. Finally, PMN were stimulated with rhHGF. PMN CD 11a, CD 11b, and CD 18 receptor expression and VEGF release was measured using flow cytometry and ELISA respectively. RESULTS: TNF-alpha, LPS and fMLP stimulation resulted in significantly increased release of PMN HGF (755+\\/-216, 484+\\/-221 and 565+\\/-278 pg\\/ml, respectively) compared to controls (118+\\/-42 pg\\/ml). IL-8 had no effect. Total HGF release following cell lysis and Western blot suggests that HGF is released from intracellular stores. Recombinant human HGF did not alter PMN adhesion receptor expression and had no effect on PMN VEGF release. CONCLUSIONS: This study demonstrates that pro-inflammatory mediators can stimulate HGF release from a PMN intracellular store and that activated PMN in addition to secreting VEGF have further angiogenic potential by releasing HGF.

  3. Human factors engineering program review model

    Energy Technology Data Exchange (ETDEWEB)

    1994-07-01

    The staff of the Nuclear Regulatory Commission is performing nuclear power plant design certification reviews based on a design process plan that describes the human factors engineering (HFE) program elements that are necessary and sufficient to develop an acceptable detailed design specification and an acceptable implemented design. There are two principal reasons for this approach. First, the initial design certification applications submitted for staff review did not include detailed design information. Second, since human performance literature and industry experiences have shown that many significant human factors issues arise early in the design process, review of the design process activities and results is important to the evaluation of an overall design. However, current regulations and guidance documents do not address the criteria for design process review. Therefore, the HFE Program Review Model (HFE PRM) was developed as a basis for performing design certification reviews that include design process evaluations as well as review of the final design. A central tenet of the HFE PRM is that the HFE aspects of the plant should be developed, designed, and evaluated on the basis of a structured top-down system analysis using accepted HFE principles. The HFE PRM consists of ten component elements. Each element in divided into four sections: Background, Objective, Applicant Submittals, and Review Criteria. This report describes the development of the HFE PRM and gives a detailed description of each HFE review element.

    This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P teaching received. Blended learning was more effective than traditional teaching for teaching human anatomy.

    Eukaryotic translation initiation factor 3 (eIF3) plays a central role in protein synthesis by organizing the formation of the 43S preinitiation complex. Using genetic tag visualization by electron microscopy, we reveal the molecular organization of ten human eIF3 subunits, including an octameric core. The structure of eIF3 bears a close resemblance to that of the proteasome lid, with a conserved spatial organization of eight core subunits containing PCI and MPN domains that coordinate functional interactions in both complexes. We further show that eIF3 subunits a and c interact with initiation factors eIF1 and eIF1A, which control the stringency of start codon selection. Finally, we find that subunit j, which modulates messenger RNA interactions with the small ribosomal subunit, makes multiple independent interactions with the eIF3 octameric core. These results highlight the conserved architecture of eIF3 and how it scaffolds key factors that control translation initiation in higher eukaryotes, including humans.

    Hirata, Y; Orth, D N

    1979-04-01

    Human epidermal growth factor (hEGF), which stimulates the growth of a variety of tissues, was first isolated from mouse submandibular glands, but is also excreted in large amounts (about 50 micrograms/day) in human urine and is probably identical to human beta-urogastrone (hUG), a potent inhibitor of stimulated gastric acid secretion. However, the primary tissue source of hEGF/hUG is as yet unknown. The hEGF/hUG in homogenates of human salivary glands and a wide variety of other endocrine and nonendocrine tissues was extracted by Amberlite CG-50 cation exchange chromatography and immune affinity chromatography using the immunoglobulin fraction of rabbit anti-hEGF serum covalently bound to agarose. The extracts were subjected to homologous hEGF RIA. Immunoreactive hEGF was found in extracts of adult submandibular gland, thyroid gland, duodenum, jejunum, and kidney, but not in several fetal tissues. The tissue immunoreactive hEGF was similar to standard hEGF in terms of immunoreactivity and elution from Sephadex G-50 Fine resin, but its concentrations were very low (1.3-5.5 ng/g wet tissue). Thus, it is not certain that these tissues represent the only source of the large amounts of hEGF/hUG that appear to be filtered by the kidneys each day.

    To prevent accident of nuclear power plant, Human Factors Center was built in the Central Research Institute of Electric Power Industry in July 1987. It developed an evaluation method of human error cases and an application method of human factors information. Now it continues analysis and application of human factors information, development of training/work support tools and research/experiment of human behavior. Japan-Human Performance Evaluation System (J-HPES) was developed as an analytical system for analysis and evaluation of human factors related to the trouble and for using the result as the common property by storage the analytical results. J-HPES has a standard procedure consisted of collecting and analyzing data and proposing the countermeasures. The analytical results are arranged by 4 kinds of charts by putting into the form of a diagram. Moreover, it tries to find the causes with indirect and potential causes. Two kinds of materials, Caution Report and Human Factors Precept by means of Illustrations, are published. People can gain access to HFC database by URL http://criepi.denken.or.jp/CRIEPI/HFC/DB. To prevent these accidents, creation of human factors culture has been required. Five kinds of teaching materials and the training method are developed. (S.Y.)

    There are many forms of psychotherapies, each distinctive in its own way. From the origins of psychotherapy, it has been suggested that psychotherapy is effective through factors that are common to all therapies. In this article, I suggest that the commonalities that are at the core of psychotherapy are related to evolved human characteristics, which include (a) making sense of the world, (b) influencing through social means, and (c) connectedness, expectation, and mastery. In this way, all psychotherapies are humanistic. (c) 2012 APA, all rights reserved.

    Yang Changpeng

    2014-08-01

    Full Text Available A systematic methodology including a computational pilot model and a pattern recognition method is presented to identify the boundary of the flight performance margin for quantifying the human factors. The pilot model is proposed to correlate a set of quantitative human factors which represent the attributes and characteristics of a group of pilots. Three information processing components which are influenced by human factors are modeled: information perception, decision making, and action execution. By treating the human factors as stochastic variables that follow appropriate probability density functions, the effects of human factors on flight performance can be investigated through Monte Carlo (MC simulation. Kernel density estimation algorithm is selected to find and rank the influential human factors. Subsequently, human factors are quantified through identifying the boundary of the flight performance margin by the k-nearest neighbor (k-NN classifier. Simulation-based analysis shows that flight performance can be dramatically improved with the quantitative human factors.

The results revealed, inter alia, that a number of factors influence the career choice of first-year teaching students. Trends that emerged from the current study include the following: many more women than men enter the teaching profession; relatively few African language speaking students choose education as a field of study and the role of parents in helping their children to choose a career cannot be underestimated.

  19. Human factors and ergonomics for primary care.

    Science.gov (United States)

    Bowie, Paul; Jeffcott, Shelly

    2016-03-01

    In the second paper of this series, we provide a brief overview of the scientific discipline of human factors and ergonomics (HFE). Traditionally the HFE focus in healthcare has been in acute hospital settings which are perceived to exhibit characteristics more similar to other high-risk industries already applying related principles and methods. This paper argues that primary care is an area which could benefit extensively from an HFE approach, specifically in improving the performance and well-being of people and organisations. To this end, we define the purpose of HFE, outline its three specialist sub-domains (physical, cognitive and organisational HFE) and provide examples of guiding HFE principles and practices. Additionally, we describe HFE issues of significance to primary care education, improvement and research and outline early plans for building capacity and capability in this setting.

    While many professionals are quite competent when dealing with operational aspects of organizational continuity, often the "human factor" does not receive adequate attention. This article provides a brief overview of a soon to be published book by the same title. It provides a comprehensive understanding of the ubiquitous yet complex reactions of the workforce to a wide array of organizational disruptions. It goes beyond the short term intervention of debriefings to describe the more extensive pre and post incident strategies required to mitigate the impact of crises on the workforce. It is important to remember: "An organization can get its phone lines back up and have its computers backed up...but its workers may still be messed up."

    Students’ individual differences pose a challenge to language teachers and influence the way in which a foreign language is learned. We are therefore invited to consider the role of our students’ personalities,motivation and cognitive styles in the language classroom. LANGUAGE teaching would be much easier if all students were alike. The number of instructional decisions would be greatly reduced; teaching methods would be rather simpler; lesson designs would not have to be modified; teachers would not have to consider alternative procedures; teacher-student interaction

    2009-01-01

    The purpose of this study was to identify and describe factors associated with successful university teaching within the cultural norms of a public university in the midwestern United States. An interpretive analysis was conducted using the educational philosophy and goal statements of 35 university professors who received Presidential Teaching Awards from the university. The professors' diverse disciplines included nursing, curriculum and instruction, accountancy, music, and political science. The authors offer nursing educators the opportunity to increase their confidence and effectiveness by "learning" from faculty members who have been recognized as exceptionally successful in teaching. Four main relevant themes associated with successful university teaching were identified: Presence, Promotion of Learning, Teachers as Learners, and Enthusiasm. The narratives of the professors helped define the meaning of successful teaching across disciplines and offer nursing faculty additional perspectives and experiences.

    2002-10-15

    Interactive teaching techniques have been used mainly in clinical teaching, with little attention given to their use in basic science teaching. With the aim of partially filling this gap, this study outlines an interactive approach to teaching anatomy based on the use of "brainstorming." The results of the students' critique of the teaching techniques are also included. Seventy-five students from the first-year nursing curriculum were tested by a structured questionnaire after three brainstorming sessions. The overall response to these sessions was very positive, indicating that students perceived this interactive technique as both interesting and useful. Furthermore, this approach may provide a useful strategy when learning the clinical courses of the upcoming academic years.

    2015-03-01

    The development of any inhalation product that does not consider the patient needs will fail. The needs of the patients must be identified and aligned with engineering options and physical laws to achieve a robust and intuitive-to-use inhaler. A close interaction between development disciplines and real-use evaluations in clinical studies or in human factor studies is suggested. The same holds true when a marketed product needs to be changed. Caution is warranted if an inhaler change leads to a change in the way the patient handles the device. Finally, the article points out potential problems if many inhaler designs are available. Do they confuse the patients? Can patients recall the correct handling of each inhaler they use? How large is the risk that different inhaler designs pose to the public health? The presentations were given at the Orlando Inhalation Conference: Approaches in International Regulation co-organised by the University of Florida and the International Pharmaceutical Aerosol Consortium on Regulation & Science (IPAC-RS) in March 2014.

  2. Human Factors Aspects of Operating Small Reactors

    2010-11-07

    The nuclear-power community has reached the stage of proposing advanced reactor designs to support power generation for decades to come. They are considering small modular reactors (SMRs) as one approach to meet these energy needs. While the power output of individual reactor modules is relatively small, they can be grouped to produce reactor sites with different outputs. Also, they can be designed to generate hydrogen, or to process heat. Many characteristics of SMRs are quite different from those of current plants, and so may require a concept of operations (ConOps) that also is different. The U.S. Nuclear Regulatory Commission (NRC) has begun examining the human factors engineering- (HFE) and ConOps- aspects of SMRs; if needed, they will formulate guidance to support SMR licensing reviews. We developed a ConOps model, consisting of the following dimensions: Plant mission; roles and responsibilities of all agents; staffing, qualifications, and training; management of normal operations; management of off-normal conditions and emergencies; and, management of maintenance and modifications. We are reviewing information on SMR design to obtain data about each of these dimensions, and have identified several preliminary issues. In addition, we are obtaining operations-related information from other types of multi-module systems, such as refineries, to identify lessons learned from their experience. Here, we describe the project's methodology and our preliminary findings.

  3. Understanding the Process and Success Factors to Increase Synergies between Research and Teaching

    2016-12-01

    Full Text Available While the synergies between research for knowledge discovery and teaching are widely accepted, the evidence is mostly implicit, verbal and poorly documented, and many times contradictive. In an effort to better understand the interaction between these important activities, the main objective of this study is to collect knowledge illustrating their synergies through specific cases. A complementary objective is to identify the important factors, which professionals should implement or avoid for increasing the likelihood that these synergies will be derived. To collect the necessary information personal interviews have been used to address the research question. The same set of questions was sent to several professionals known to have extensive experience in the areas of academic research and teaching. The respondents were asked to: 1. briefly describe the knowledge area in which the synergies occurred; 2. For the specified knowledge area, to please describe in summary form but specifically how they derived the synergy between research and teaching; and 3. Based on their personal experience, to please identify the important factors to increase the likelihood that academic research will produce benefits for teaching, and vice versa. The results strongly corroborate the importance of academic research for effective teaching. Based on the results, a set of recommendations are made to faculty members and school administrators to further promote academic research as an important factor for more effective teaching.

  4. Teachers' beliefs about science teaching and context factors: Implications for teaching and learning science at the middle school level

    Science.gov (United States)

    Pea, Celeste H.

    Current research shows that teachers' beliefs have been virtually ignored in science education reform efforts spearheaded by the development of national, state, and local standards. Since the aim of science education reform is to improve scientific literacy for all students, increasingly, researchers are questioning the lack of attention to teachers' beliefs and are calling for more research to examine teachers' beliefs and the influence of school environmental factors on their classroom practices. The purpose of this study was to explore, investigate, and analyze data that might reveal middle school science teachers' beliefs about science teaching and how school environmental factors influence their classroom behavior. The mixed methods study was conducted in a large urban/suburban county in an eastern state in the United States. Data were collected through a Likert-style survey and interview and observation sessions. Ninety-one middle school science teachers completed the survey. Three teachers from the survey sample also participated in the interview and observation sessions. The findings from the quantitative and qualitative data indicated that most of the middle school science teachers in this study believed that science teaching should be student-centered, and science instruction should be based on an inquiry-based approach to teaching and learning. They also believed that the state and county standards were the most important factors in helping teachers to use inquiry-based instructional strategies to teach science. In addition to the science standards, the middle school science teachers believed that peer and principal support were critical to their success as teachers, and that instructional materials and supplies were readily available to help them teach science. The findings from the study indicated that few school environmental factors affected the middle school teachers' classroom practices. However, time (to participate in more professional activities

    2015-10-01

    Technology has revolutionized in the field of Education. The importance of technology in schools cannot be ignored. While it is important that mathematics teachers should have positive attitudes towards adopting ICT in their teaching, various problems can arise when integrating ICT into classroom lessons. This study explored the factors that influence the attitudes of mathematic teachers in the integration of ICT in the teaching and learning process. A total of 187 mathematics teachers from the state of Selangor in Malaysia were randomly selected from a stratified cluster sample. The research examined five factors that were postulated to impact teachers' attitudes towards the integration of ICT in their lessons, viz. teachers' technology competence, school culture, access to ICT, school support, and years of classroom teaching experience. The findings showed that the teachers' attitudes towards using ICT in teaching and learning were positively correlated with the teachers' technology competence [r = .41; p ICT school culture [r = .261; p ICT resources [r = .220; p ICT in teaching and learning [r = -0.192; p ICT in the classroom was explained by the variation in teachers' technology competence, school support and school culture, with the effects of teaching experience and ICT resource access being negligible.

  11. Beginning elementary school teachers' perceptions of structural and cultural context factors impacting their science teaching

    Science.gov (United States)

    Sterling, Hillary A.

    Science maintains low status in many elementary classrooms. Beginning teachers find it difficult to teach science effectively. The Teacher-Centered Systemic Reform Model suggests there are personal, structural, and cultural factors that impact teaching practices. The questions that drove this study were: (a) How do beginning teachers perceive structural and cultural factors of the TCSR model as affecting their science teaching practices? (b) How do those perceptions compare between beginning teachers who teach science and those who do not? (c) How do beginning teachers' perceptions compare to those of principals and veteran teachers? The model was used to collect and analyze data on the perceptions of factors that influenced beginning teachers' science teaching practices. A case study involved six beginning teachers from three elementary schools in the southwestern United States during the 2005--2006 school year. Through an initial survey, two groups of beginning teachers were first identified as (a) those who taught and liked science, and (b) those who did not teach or like science. Three teachers from each group were selected to participate in the study that consisted of semi-structured interviews, observations, and review of artifacts. These data were compared with interview data from three veteran teachers and three principals. The findings of this study supported the TCSR model and confirmed that the beginning teachers did perceive certain structural context factors (e.g., curriculum, materials, time, professional development, district requirements, classroom management), and cultural context factors (e.g., district-wide low priority of science) as having an impact on their science teaching. The veteran teachers' perceptions more closely matched those of the beginning teachers' than did those of the principals. Despite the contextual influences, the beginning teachers' perceptions ultimately differed in teacher thinking (i.e., those who taught science had

    Human factors have been well known as one of the key factors to the system effectiveness as well as the efficiency and safety of nuclear power plants(NPPs). Human factors engineering(HFE) are included in periodic safety review(PSR) on the existing NPPs and the formal safety assessment for the new ones. However, HFE for NPPs is still neither popular in practice nor concrete in methodology. Especially, the human factors guidelines, which are the most frequent form of human factors engineering in practice, reveal the limitations in their applications. We discuss the limitations and their casual factors found in human factors guidelines in order to lesson the workload of HFE practitioners and to improve the applicability of human factors guidelines. According to the purposes and the phases of HFE for NPPs, more selective items and specified criteria should be prepared carefully in the human factors guidelines for the each HFE applications in practice. These finding on the human factors guidelines can be transferred to the other HFE application field, such as military, aviation, telecommunication, HCI, and product safety.

    Writing teaching materials is one of the generic pedagogical skills. Teachers and pre-service teachers should be trained to have the skills of writing teaching materials. This study examines the factors that influence the skills of writing in the disciplines among pre-service physics teachers. This study in particular aims to contribute to the development of science writing in the disciplines and to the organization of workshops on writing teaching materials for pre-service teachers. The problems of this research are formulated in the question of what are the factors that influence the skills of pre-service physics teachers in writing teaching materials. The research adopted mixed methods with embedded experimental design. The research subjects were 18 students enrolled in the school physics course. The instruments used consisted of conceptual understanding tests, learning strategy questionnaire, tests of the multiple representation skills, and one-on-one semi- structured interview. Results of data analysis show that the ability and skills of writing physics teaching materials of the pre- service physics teachers are determined by the factors of conceptual understanding of the subject matter with a contribution of 20%, the skills of making multiple representations of concepts with a contribution of 9.8% and students' self-regulation and learning strategy with a contribution of 33.5%. There are other factors that have not been investigated in this study; therefore, it is recommended that future research conduct further investigation on other factors that influence pre-service teachers' skills in writing physics teaching materials.

      大学人文学科的理论知识乍看枯燥、深奥,但如果我们在教学中能激活蕴含在其中的有趣的因素,并辅之以诗意渗透,定能收到不一般的教学效果。以现代汉语语音教学为例,其具体的教学策略可进行如下创新:以声腔多样的方言为趣点激活语音教学全盘棋;在平仄起伏、韵律和谐中展开语音的诗意教学;结合现实需求进行应用能力的培养。%  Theoretical knowledge of university humanities seems boring and profound, but if we can activate the interesting factors in it, and teach it poetically, our teaching effect will be quite different. Taking Modern Chinese pronunciation teach-ing for example, specific teaching strategies can be innovated as follows:to activate the pronunciation teaching with a vari-ety of dialects, to begin poetic teaching of pronunciation with the rise and fall of the level and oblique tones as well as rhythmic harmony, and to train students’ application ability based on the needs of the society.

  8. Factors Affecting the Development and Evolution of the Teaching Beliefs of Future Geoscience Professors

    Science.gov (United States)

    Chapman, LeeAnna Tiffany Young

    The pedagogical beliefs of university instructors influence how they design their courses and whether they choose to use research-validated teaching methods that have been shown to improve student learning. The next generation of professors will be drawn from today's graduate students and post-doctoral fellows but we know relatively little about their preparation to use research-validated teaching practices. We followed a broad population of geoscience graduate students and post-docs over a three year period to evaluate changes in teaching beliefs. This study employed a longitudinal mixed-methods experimental design including surveys, short interviews, and longer case study interviews to: a) collect information on the teaching beliefs of geoscience graduate students and post-doctoral scholars; and b) identify experiences that contributed to the development of reformed teaching beliefs and their interest in an academic career. We collected initial surveys from more than 600 participants and re-surveyed more than 300 of these participants 12-18 months later. We conducted an initial round of interviews with 61 participants and repeat interviews with 31 of these individuals. The survey utilized was the Beliefs about Reformed Teaching and Learning (BARSTL); the interview tool was the Teacher Belief Interview (TBI). Finally, we conducted detailed case study interviews with a sample of ten participants who were either PhD students, post-doctoral scholars, or beginning professors at the time of the interviews. The data were examined to determine if there was a difference in beliefs about teaching on the basis of factors including number of years in graduate school, teaching assistant (TA) experiences, gender, and participation in professional development. Data from the large initial population were interpreted to show that participation in teaching-related professional development was the experience that was most likely to result in more reformed pedagogical beliefs among

    2015-09-01

    Full Text Available The purpose of this article, which can be envision as an essay, is to present a pedagogical-didactic strategy for human rights education focusing on the controversy. Advancements and setbacks faced by human rights education in Latin America are exposed in order to support this strategy. Therefore, it indicates that education has denied the conflict and explains the need for its inclusion under the idea of ‘controversial issue’. Additionally, the existence of conflicts in the interpretation, violation and/or respect for human rights is pointed out. The principal tensions that cross human rights are displayed. Based on the above, the need to support the existence of a human rights education focusing on the conflict and central components of its teaching strategy are described, and it ends by referring to its didactic approach and the role which should be assumed by faculty when teaching human rights including the conflict.

    Science.gov (United States)

    Vollmer, Anna-Lisa; Wrede, Britta; Rohlfing, Katharina J; Oudeyer, Pierre-Yves

    2016-01-01

    One of the big challenges in robotics today is to learn from human users that are inexperienced in interacting with robots but yet are often used to teach skills flexibly to other humans and to children in particular. A potential route toward natural and efficient learning and teaching in Human-Robot Interaction (HRI) is to leverage the social competences of humans and the underlying interactional mechanisms. In this perspective, this article discusses the importance of pragmatic frames as flexible interaction protocols that provide important contextual cues to enable learners to infer new action or language skills and teachers to convey these cues. After defining and discussing the concept of pragmatic frames, grounded in decades of research in developmental psychology, we study a selection of HRI work in the literature which has focused on learning-teaching interaction and analyze the interactional and learning mechanisms that were used in the light of pragmatic frames. This allows us to show that many of the works have already used in practice, but not always explicitly, basic elements of the pragmatic frames machinery. However, we also show that pragmatic frames have so far been used in a very restricted way as compared to how they are used in human-human interaction and argue that this has been an obstacle preventing robust natural multi-task learning and teaching in HRI. In particular, we explain that two central features of human pragmatic frames, mostly absent of existing HRI studies, are that (1) social peers use rich repertoires of frames, potentially combined together, to convey and infer multiple kinds of cues; (2) new frames can be learnt continually, building on existing ones, and guiding the interaction toward higher levels of complexity and expressivity. To conclude, we give an outlook on the future research direction describing the relevant key challenges that need to be solved for leveraging pragmatic frames for robot learning and teaching.

    The Usability project addresses the need for research in the area of metrics and methodologies used in hardware and software usability testing in order to define quantifiable and verifiable usability requirements. A usability test is a human-in-the-loop evaluation where a participant works through a realistic set of representative tasks using the hardware/software under investigation. The purpose of this research is to define metrics and methodologies for measuring and verifying usability in the aerospace domain in accordance with FY09 focus on errors, consistency, and mobility/maneuverability. Usability metrics must be predictive of success with the interfaces, must be easy to obtain and/or calculate, and must meet the intent of current Human Systems Integration Requirements (HSIR). Methodologies must work within the constraints of the aerospace domain, be cost and time efficient, and be able to be applied without extensive specialized training.

    Full Text Available Background: Leptospirosis is one of the most under diagnosed and underreported disease in both developed and developing countries including India. It is established that environmental conditions and occupational habit of the individuals put them at risk of acquiring disease, which varies from community to community. Various seroprevalence studies across the world have documented emerging situation of this neglected tropical disease, but limited have probed to identify the risk factors, especially in India. Objectives: The objective of this study was to identify the environmental and occupational risk factors associated with the disease in Udupi District. Materials and Methods: This population-based case-control study was carried out in Udupi, a District in Southern India from April 2012 until August 2012. Udupi is considered to be endemic for Leptospirosis and reported 116 confirmed cases in the year 2011. Seventy of 116 laboratory confirmed cases and 140 sex matched neighborhood healthy controls participated in the study. A predesigned, semi-structured and validated questionnaire was used for data collection through house to house visit and observations were noted about environmental conditions. Univariate analysis followed by multivariate analysis (back ward conditional logistic regression was performed by using STATA version 9.2 (StataCorp, College Station, TX, USA to identify potential risk factors. Results: Occupational factors such as outdoor activities (matched odds ratio [OR] of 3.95, 95% confidence interval [CI]: 1.19-13.0, presence of cut or wound at body parts during work (matched OR: 4.88, CI: 1.83-13.02 and environmental factors such as contact with rodents through using the food materials ate by rat (matched OR: 4.29, CI: 1.45-12.73 and contact with soil or water contaminated with urine of rat (matched OR: 4.58, CI: 1.43-14.67 were the risk factors identified to be associated with disease.

  18. Human factors in resuscitation: Lessons learned from simulator studies

    Directory of Open Access Journals (Sweden)

    Hunziker S

    2010-01-01

    Full Text Available Medical algorithms, technical skills, and repeated training are the classical cornerstones for successful cardiopulmonary resuscitation (CPR. Increasing evidence suggests that human factors, including team interaction, communication, and leadership, also influence the performance of CPR. Guidelines, however, do not yet include these human factors, partly because of the difficulties of their measurement in real-life cardiac arrest. Recently, clinical studies of cardiac arrest scenarios with high-fidelity video-assisted simulations have provided opportunities to better delineate the influence of human factors on resuscitation team performance. This review focuses on evidence from simulator studies that focus on human factors and their influence on the performance of resuscitation teams. Similar to studies in real patients, simulated cardiac arrest scenarios revealed many unnecessary interruptions of CPR as well as significant delays in defibrillation. These studies also showed that human factors play a major role in these shortcomings and that the medical performance depends on the quality of leadership and team-structuring. Moreover, simulated video-taped medical emergencies revealed that a substantial part of information transfer during communication is erroneous. Understanding the impact of human factors on the performance of a complex medical intervention like resuscitation requires detailed, second-by-second, analysis of factors involving the patient, resuscitative equipment such as the defibrillator, and all team members. Thus, high-fidelity simulator studies provide an important research method in this challenging field.

The study explored (1) the extent and nature of evolution education; (2) the role of teacher's attitudes, knowledge and beliefs in the teaching of evolution; (3) the nature and sources of student misconceptions; and (4) the extent to which conceptual change teaching can induce changes in these misconceptions. Questionnaires, interviews, and an experimental intervention were used to ascertain the factors affecting the teaching and learning of evolution. Among the study's major findings: (1) While evolution is present in the official curriculum, it is not treated as a central unifying theme. (2) In actual teaching evolution is completely neglected. (3) This neglect is due to several factors including: the religious beliefs of teachers; deficient pre-service training in particular poor training in history and philosophy of science, and deficient content and methods knowledge. (4) Students possess a wide variety of misconceptions about evolutionary theory. While some of these are ascribable to religion, many are related to other aspects of student affect, knowledge and cognition, including: (a) a misunderstanding of the nature of science; (b) methodological, epistemological and ontological commitments which difficultate comprehension; (c) the distorting influence of an anthropocentric, urban experience; (d) deficiencies in prior knowledge; and (e) an ahistoric worldview. (5) Conceptual change teaching was found to be more effective in transforming student views towards more scientific ones, than traditional didactic instruction. Conceptual change instruction: (a) increased the explanatory repertoire of students; (b) promoted greater changes towards more scientific conceptions; (c) increased student acceptance and understanding of evolutionary theory, and (d) induced more students to incorporate evolution in their explanations of biological phenomena.

    1989-01-01

    A survey oriented towards identifying the human factors issues in regard to the use of advanced instrumentation and controls (I C) in the nuclear industry was conducted. A number of United States (US) and Canadian nuclear vendors and utilities were participants in the survey. Human factors items, subsumed under the categories of computer-generated displays (CGD), controls, organizational support, training, and related topics, were discussed. The survey found the industry to be concerned about the human factors issues related to the implementation of advanced I C. Fifteen potential human factors problems were identified. They include: the need for an advanced I C guideline equivalent to NUREG-0700; a role change in the control room from operator to supervisor; information overload; adequacy of existing training technology for advanced I C; and operator acceptance and trust. 11 refs., 1 tab.

    This report describes the basic aspects of control room modernization projects in the U.S. nuclear industry and the need for supplementary guidance on the integration of human factors considerations into the licensing and regulatory aspects of digital upgrades. The report pays specific attention to the integration of principles described in NUREG-0711 (Human Factors Engineering Program Review Model) and how supplementary guidance can help to raise general awareness in the industry regarding the complexities of control room modernization projects created by many interdependent regulations, standards and guidelines. The report also describes how human factors engineering principles and methods provided by various resources and international standards can help in navigating through the process of licensing digital upgrades. In particular, the integration of human factors engineering guidance and requirements into the process of licensing digital upgrades can help reduce uncertainty related to development of technical bases for digital upgrades that will avoid the introduction of new failure modes.

    It has been reported that virtual reality can be a useful tool for ergonomics study. The proposed integrated simulation system aims at measuring operator's performance in an interactive way for 2D control panel design. By incorporating some sophisticated virtual reality hardware/software, the system allows natural human-system and/or human-human interaction in a simulated virtual environment; enables dynamic objective measurement of human performance; and evaluates the quality of the system design in human factors perspective based on the measurement. It can also be for operation training for some 2D control panels.

  4. Pragmatic frames for teaching and learning in human-robot interaction: review and challenges

    Directory of Open Access Journals (Sweden)

    Anna-Lisa Vollmer

    2016-10-01

    Full Text Available One of the big challenges in robotics today is to learn from human users that are inexperienced in interacting with robots, but yet are often used to teach skills flexibly to other humans, and to children in particular. A potential route towards natural and efficient learning and teaching in HRI is to leverage the social competences of humans and the underlying interactional mechanisms. In this perspective, this article discusses the importance of pragmatic frames as flexible interaction protocols that provide important contextual cues to enable learners to infer new action or language skills, and teachers to convey these cues. After defining and discussing the concept of pragmatic frame, grounded in decades of research in developmental psychology, we study a selection of HRI work in the literature which has focused on learning-teaching interaction, and analyze the interactional and learning mechanisms that were used in the light of pragmatic frames. This allows us to show that many of them have already used in practice, but not always explicitly, basic elements of the pragmatic frames machinery.However, we also show that pragmatic frames have so far been used in a very restricted way as compared to how they are used in human-human interaction, and argue that this has been an obstacle preventing robust natural multi-task learning and teaching in HRI. In particular, we explain that two central features of human pragmatic frames, mostly absent of existing HRI studies, are that 1 social peers use rich repertoires of frames, potentially combined together, to convey and infer multiple kinds of cues; 2 new frames can be learnt continually, building on existing ones and guiding the interaction towards higher levels of complexity and expressivity.To conclude, we give an outlook on the future research direction describing the relevant key challenges that need to be solved for leveraging pragmatic frames for robot learning and teaching.

    The design and use of mechanical compression tools in electrical distribution functions were examined from the point of view of effects of design and use of tools on human operators. Various alternative tools such as manual compression tools, battery operated tools, wedge pressure tools, hydraulic tools, and insulating piercing connectors were also examined for purposes of comparison. Results of the comparative assessment were summarized and a tool satisfaction ratings table was produced for Burndy MD6, Huskie-Robo (REC 258) and Ampact (small) tools, rating level of effort, fatigue experienced, tool mass, force required to crimp, ease of use, comfort while using the tool, maneuverability, and overall satisfaction. Both the battery operated tool as well as the wedge pressure tool have been found to have ergonomic advantages over the mechanical compression tool.

  3. Effects of a Cooperative Learning Strategy on the Effectiveness of Physical Fitness Teaching and Constraining Factors

    Tsui-Er Lee

    2014-01-01

    Full Text Available The effects of cooperative learning and traditional learning on the effectiveness and constraining factors of physical fitness teaching under various teaching conditions were studied. Sixty female students in Grades 7–8 were sampled to evaluate their learning of health and physical education (PE according to the curriculum for Grades 1–9 in Taiwan. The data were quantitatively and qualitatively collected and analyzed. The overall physical fitness of the cooperative learning group exhibited substantial progress between the pretest and posttest, in which the differences in the sit-and-reach and bent-knee sit-up exercises achieved statistical significance. The performance of the cooperative learning group in the bent-knee sit-up and 800 m running exercises far exceeded that of the traditional learning group. Our qualitative data indicated that the number of people grouped before a cooperative learning session, effective administrative support, comprehensive teaching preparation, media reinforcement, constant feedback and introspection regarding cooperative learning strategies, and heterogeneous grouping are constraining factors for teaching PE by using cooperative learning strategies. Cooperative learning is considered an effective route for attaining physical fitness among students. PE teachers should consider providing extrinsic motivation for developing learning effectiveness.

    2016-09-01

    This study tests the reliability of a system (FINANS) to collect and analyze incident reports in the financial trading domain and is guided by a human factors taxonomy used to describe error in the trading domain. Research indicates the utility of applying human factors theory to understand error in finance, yet empirical research is lacking. We report on the development of the first system for capturing and analyzing human factors-related issues in operational trading incidents. In the first study, 20 incidents are analyzed by an expert user group against a referent standard to establish the reliability of FINANS. In the second study, 750 incidents are analyzed using distribution, mean, pathway, and associative analysis to describe the data. Kappa scores indicate that categories within FINANS can be reliably used to identify and extract data on human factors-related problems underlying trading incidents. Approximately 1% of trades (n = 750) lead to an incident. Slip/lapse (61%), situation awareness (51%), and teamwork (40%) were found to be the most common problems underlying incidents. For the most serious incidents, problems in situation awareness and teamwork were most common. We show that (a) experts in the trading domain can reliably and accurately code human factors in incidents, (b) 1% of trades incur error, and (c) poor teamwork skills and situation awareness underpin the most critical incidents. This research provides data crucial for ameliorating risk within financial trading organizations, with implications for regulation and policy. © 2016, Human Factors and Ergonomics Society.

    Lombardi, Doug; Sinatra, Gale M.

    2013-01-01

    Global climate change is receiving increasing attention as a classroom topic. At the same time, research has shown that individuals have strong emotions about the topic. Emotions about controversial topics and individuals' dispositions toward knowledge have been shown to influence judgments about these topics. This study examined the relationships among preservice elementary and in-service secondary science teachers' emotions about and plausibility perceptions of climate change, background knowledge of weather and climate distinctions (a principle related to understanding climate change), and dispositions toward knowledge. Teachers' topic emotions (anger and hopelessness) were significant predictors of plausibility perceptions, with more anger associated with lesser plausibility and greater hopelessness associated with higher plausibility. Decisiveness-an urgent desire to reach closure-was also significantly related to plausibility perceptions with greater decisiveness associated with reduced plausibility perceptions. In-service secondary teachers who do not currently teach about climate change exhibited greater anger and decisiveness than preservice elementary teachers and in-service secondary teachers who do teach about climate change. Implications for climate literacy education are discussed.

    2011-01-01

    With the ending of the Space Shuttle Program, it is critical that we not forget the Human Factors lessons we have learned over the years. At every phase of the life cycle, from manufacturing, processing and integrating vehicle and payload, to launch, flight operations, mission control and landing, hundreds of teams have worked together to achieve mission success in one of the most complex, high-risk socio-technical enterprises ever designed. Just as there was great diversity in the types of operations performed at every stage, there was a myriad of human factors that could further complicate these human systems. A single mishap or close call could point to issues at the individual level (perceptual or workload limitations, training, fatigue, human error susceptibilities), the task level (design of tools, procedures and aspects of the workplace), as well as the organizational level (appropriate resources, safety policies, information access and communication channels). While we have often had to learn through human mistakes and technological failures, we have also begun to understand how to design human systems in which individuals can excel, where tasks and procedures are not only safe but efficient, and how organizations can foster a proactive approach to managing risk and supporting human enterprises. Panelists will talk about their experiences as they relate human factors to a particular phase of the shuttle life cycle. They will conclude with a framework for tying together human factors lessons-learned into system-level risk management strategies.

    Full Text Available In this article we present the results of a qualitative research study on the pedagogical factors that influence English teaching in four public schools of Medellín, Colombia. Twelve teachers were interviewed regarding three linguistic principles: communicative competence, native language effect, and interlanguage. The data analysis led to the identification of various factors, such as teachers’ linguistic ego, view of their teaching role, and attitude towards English, which shape English teaching and are tied to teachers’ education. It was concluded that teachers’ professional development must tap into these factors so teachers can effectively revise their beliefs and adjust their practices to ensure a high qualityin their teaching.En este artículo se presentan los resultados de una investigación cualitativa acerca de los factorespedagógicos que influyen en la enseñanza del inglés en cuatro escuelas públicas de Medellín (Colombia. Doce maestros fueron entrevistados sobre tres principios lingüísticos: competencia comunicativa, efecto de la lengua nativa e interlenguaje. A partir del análisis se concluyó que factores como el ego lingüístico, la percepción del papel del docente y la actitud frente al inglés son determinantes en laenseñanza de esta lengua. Se concluye que dichos factores deben ser incorporados en los programas de desarrollo profesional para que los maestros puedan revisar sus creencias y ajustar sus prácticas efectivamente y así asegurar la calidad de su enseñanza.

    We will examine how the humanities -- the visual arts, science fiction, poetry, music, etc. -- can be used in teaching introductory astronomy courses for non-science majors. A number of instructors have found innovative ways to show how astronomy has a deep influence on other areas of human culture and how the humanities can illuminate our students' understanding of the universe. A few astronomers are also making original contributions at the interface of astronomy and the humanities. The panel of speakers for the session will consists of: Gregory Benford (U. of California, Irvine): Using Science Fiction to Teach Astronomy: Promise and Pitfalls William Hartmann (Planetary Science Institute): Science and Art in the Classroom Andrew Fraknoi (Foothill College & A.S.P.): The Humanities in the Astronomy Classroom: Activities and Projects George Greenstein (Amherst College) will be the session moderator. Time will be set aside for brief summaries of the poster papers associated with this session and for discussion. Participants will receive a resource guide to using the humanities for astronomy teaching.

    Full Text Available Purpose: The purpose of this paper is to review the literature, for both theoretical foundations and empirical research, in order to establish relationships between the variables related to human factors and their impact on productivity.Design/methodology/approach: The strategy employed corresponds to a descriptive non-experimental design, which is the establishment of three criteria for the literature review, in order to narrow down the topic to research works relating productivity with the human factor. This was investigated in databases and journals dealing with related topics, in addition to consulting doctoral theses and published books concerning the influence of human factors on productivity. About 250 papers which were considered the most relevant for the research were selected.Findings:  As a result of this exploration the classification of the factors in two dimensions that are manifested in people when they act in organizations was highlighted: the psychological and the psychosocial dimension. Human factors included in these dimensions are: individual factors (motivation, skills, job satisfaction, identification, commitment and involvement with the organization, group factors (participation, cohesion and management conflict and organizational factors (organizational culture, organizational climate and leadership. All these factors have an impact on the productivity of the organization and are addressed in this research.Originality/value: The selected variables were used to formulate a model that incorporates the human factors identified and considers the phenomenon in a comprehensive manner. It will be addressed through multivariate analysis, with the possible application of structural equations in order to assess the causal relationships that may exist between factors and productivity.

    Three-dimensional (3D) visualization of neuroanatomy can be challenging for medical students. This knowledge is essential in order for students to correlate cross-sectional neuroanatomy and whole brain specimens within neuroscience curricula and to interpret clinical and radiological information as clinicians or researchers. This study implemented and evaluated a new tool for teaching 3D neuroanatomy to first-year medical students at Boston University School of Medicine. Students were randomized into experimental and control classrooms. All students were taught neuroanatomy according to traditional 2D methods. Then, during laboratory review, the experimental group constructed 3D color-coded physical models of the periventricular structures, while the control group re-examined 2D brain cross-sections. At the end of the course, 2D and 3D spatial relationships of the brain and preferred learning styles were assessed in both groups. The overall quiz scores for the experimental group were significantly higher than the control group (t(85) = 2.02, P higher in the experimental group (F₁(,)₈₅ = 5.48, P = 0.02). When surveyed, 84% of students recommended repeating the 3D activity for future laboratories, and this preference was equally distributed across preferred learning styles (χ² = 0.14, n.s.). Our results suggest that our 3D physical modeling activity is an effective method for teaching spatial relationships of brain anatomy and will better prepare students for visualization of 3D neuroanatomy, a skill essential for higher education in neuroscience, neurology, and neurosurgery.

    Jegede, Olugbemiro J.; Olajide, Janet O.

    Wait-time, a variable related to questioning in a teaching-learning situation, has been found to have implications for the inquiry mode of science teaching especially in Western classroom environments. Aside from the fact that the literature is very sparse in this area about what obtains in developing countries, nothing appears to be available with regard to how wait-time interacts with the sociocultural factors within non-Western science classrooms. In a non-Western country such as Nigeria where most science programs in schools are inquiry-oriented, do teachers take notice of, and effectively use, wait-time in the teaching-learning process? Are science teachers able to effectively use the mediating role of sociocultural factors in science teaching in a traditional environment which expects children to be seen only and not heard? The main purpose of this study was to investigate the wait-time of Nigerian integrated science teachers in relation to the amount of students' participation in inquiry. This study also investigated the relationship between wait-time and sociocultural attitudinal factors prevalent in traditional societies. The instruments used for data collection were the Hough's Observational Schedule and a modified version of the Socio-Cultural Environment Scale (SCES); a stop-watch was used to measure the wait-time of audio-recorded integrated science lessons of 37 integrated science teachers from selected junior secondary schools in Kaduna State, Nigeria. The results showed that the average wait-time TT and wait-time ST of the integrated science teachers was 3.0 seconds and 0.7 seconds, respectively. The study reported the amount of student participation in the student-teacher classroom discourse to be very low. Wait-time was also shown to have a strong relationship with sociocultural factors of authoritarianism, goal structure, societal expectation, and traditional worldview. The pedagogical and curricular implications of the results have been

    Dengue fever is the most frequent arthropod-borne viral disease of humans, with almost half of the world's population at risk of infection. The high prevalence, lack of an effective vaccine, and absence of specific treatment conspire to make dengue fever a global public health threat. Given their compact genomes, dengue viruses (DENV-1-4) and other flaviviruses probably require an extensive number of host factors; however, only a limited number of human, and an even smaller number of insect host factors, have been identified. Here we identify insect host factors required for DENV-2 propagation, by carrying out a genome-wide RNA interference screen in Drosophila melanogaster cells using a well-established 22,632 double-stranded RNA library. This screen identified 116 candidate dengue virus host factors (DVHFs). Although some were previously associated with flaviviruses (for example, V-ATPases and alpha-glucosidases), most of the DVHFs were newly implicated in dengue virus propagation. The dipteran DVHFs had 82 readily recognizable human homologues and, using a targeted short-interfering-RNA screen, we showed that 42 of these are human DVHFs. This indicates notable conservation of required factors between dipteran and human hosts. This work suggests new approaches to control infection in the insect vector and the mammalian host.

    2012-12-01

    To provide a review of human factors research within the context of surgery. We searched PubMed for relevant studies published from the earliest available date through February 29, 2012. The search was performed using the following keywords: human factors, surgery, errors, teamwork, communication, stress, disruptions, interventions, checklists, briefings, and training. Additional articles were identified by a manual search of the references from the key articles. As 2 human factors specialists, a senior clinician, and a junior clinician, we carefully selected the most appropriate exemplars of research findings with specific relevance to surgical error and safety. Seventy-seven articles of relevance were selected and reviewed in detail. Opinion pieces and editorials were disregarded; the focus was solely on articles based on empirical evidence, with a particular emphasis on prospectively designed studies. The themes that emerged related to the development of human factors theories, the application of those theories within surgery, a specific interest in the concept of flow, and the theoretical basis and value of human-related interventions for improving safety and flow in surgery. Despite increased awareness of safety, errors routinely continue to occur in surgical care. Disruptions in the flow of an operation, such as teamwork and communication failures, contribute significantly to such adverse events. While it is apparent that some incidence of human error is unavoidable, there is much evidence in medicine and other fields that systems can be better designed to prevent or detect errors before a patient is harmed. The complexity of factors leading to surgical errors requires collaborations between surgeons and human factors experts to carry out the proper prospective and observational studies. Only when we are guided by this valid and real-world data can useful interventions be identified and implemented.

    Full Text Available The main activity of social robots is to interact with people. In order to do that, the robot must be able to understand what the user is saying or doing. Typically, this capability consists of pre-programmed behaviors or is acquired through controlled learning processes, which are executed before the social interaction begins. This paper presents a software architecture that enables a robot to learn poses in a similar way as people do. That is, hearing its teacher’s explanations and acquiring new knowledge in real time. The architecture leans on two main components: an RGB-D (Red-, Green-, Blue- Depth -based visual system, which gathers the user examples, and an Automatic Speech Recognition (ASR system, which processes the speech describing those examples. The robot is able to naturally learn the poses the teacher is showing to it by maintaining a natural interaction with the teacher. We evaluate our system with 24 users who teach the robot a predetermined set of poses. The experimental results show that, with a few training examples, the system reaches high accuracy and robustness. This method shows how to combine data from the visual and auditory systems for the acquisition of new knowledge in a natural manner. Such a natural way of training enables robots to learn from users, even if they are not experts in robotics.

    Introduction: Human performance in organizations reflects on the knowledge, skills, behaviors, and values. Since the abilities and skills will help the organization to better performance and productivity, any expenditure on education and development is a long term investment that as long as the organization can benefit from it. The aim of this research is assessment of influence of structured workshops by resource management at different levels of acquaintance, skills, updates, and upgrades in field of teaching before teaching for invited professors and tuition. Methodology: So in a case study in the first semester of the academic year of 91- 92, 30 teachers with no teaching experience in tuition PNU after internal interview was selected as a sample. Then their awareness of indicators of effective teaching and training allowance of two categories before and after the workshop assessed and evaluated by a questionnaire. Results: The results of descriptive and inferential statistical analysis indicates that the 52/4% of the professors of the age group 25-30, and 38/1% are in the age group 31-36. Also 76/2% percent of teachers have graduated from the National University and the rest of the teacher have graduated from Azad or Payamenoor University. Also there is significant difference between the knowledge of laws and regulations and effective teaching index before and after the workshop on four indicators: evaluation of students, teaching methods, planning, behavioral patterns and rules and regulations PNU. So it shows the impact of targeted workshops and the role of education experts in the process of recreating human resource management in higher education systems. PMID:25870529

    Blood type, which harbors abundant genetics meaning, is one of the most common phenotypes in human life. With the development of science and technology, its significance is unceasingly updated and new finding is increasingly emerging, which constantly attracts people to decipher the heredity mechanism of blood type. In addition to four main associated contents, i.e., Mendelian inheritance, genetic linkage, gene mutations, and chromosome abnormalities, the blood type case also covers many other aspects of the genetics knowledge. Based on the genetic knowledge context, we can interest the students and improve the teaching output in genetic teaching practice by combining with explaining ABO blood type case and heredity mechanism, expanding leucocyte groups, and introducing infrequent blood type such as Bombay blood, Rh and MN. By carrying out the related experimental teaching, we could drive the student to integrate theory with practice. In genetic experimental teaching, 80% of the students chose this optional experiment, molecular identification of ABO blood type, and it greatly interested them. Using appropriate blood type case in teaching related knowledge, organizing PPT exhi-bition and the debating discussion activities, it could provide opportunities for student to propose their own opinions, guide the student to thinking deeply, and develop their abilities to analyze and solve problem. Afterwards, students will gain in-depth comprehension about the fundamental knowledge of genetics.

    For the design and construction of new nuclear power plants as well as for maintenance and operation of the existing ones new man-machine interface designs and modifications are been produced. For these new designs Human Factor Engineering must be applied the same as for any other traditional engineering discipline. Advantages of implementing adequate Human Factor Engineering techniques in the design of nuclear reactors have become not only a fact recognized by the majority of engineers and operators but also an explicit requirement regulated and mandatory for the new designs of the so called advanced reactors. Additionally, the big saving achieved by a nuclear power plant having an operating methodology which significantly decreases the risk of operating errors makes it necessary and almost vital its implementation. The first step for this is preparing a plan to incorporate all the Human Factor Engineering principles and developing an integral design of the Instrumentation and Control and Man-machine interface systems.

    Advanced human-system interface (HSI) technology is being integrated into existing nuclear plants as part of plant modifications and upgrades. The result of this trend is that hybrid HSIs are created, i.e., HSIs containing a mixture of conventional (analog) and advanced (digital) technology. The purpose of the present research is to define the potential effects of hybrid HSIs on personnel performance and plant safety and to develop human factors guidance for safety reviews of them where necessary. In support of this objective, human factors issues associated with hybrid HSIs were identified. The issues were evaluated for their potential significance to plant safety, i.e., their human performance concerns have the potential to compromise plant safety. The issues were then prioritized and a subset was selected for design review guidance development.

    As NASA is planning to send humans deeper into space than ever before, adequate crew health and performance will be critical for mission success. Within the NASA Human Research Program (HRP), the Space Human Factors and Habitability (SHFH) team is responsible for characterizing the risks associated with human capabilities and limitations with respect to long-duration spaceflight, and for providing mitigations (e.g., guidelines, technologies, and tools) to promote safe, reliable and productive missions. SHFH research includes three domains: Advanced Environmental Health (AEH), Advanced Food Technology (AFT), and Space Human Factors Engineering (SHFE). The AEH portfolio focuses on understanding the risk of microbial contamination of the spacecraft and on the development of standards for exposure to potential toxins such as chemicals, bacteria, fungus, and lunar/Martian dust. The two risks that the environmental health project focuses on are adverse health effects due to changes in host-microbe interactions, and risks associated with exposure to dust in planetary surface habitats. This portfolio also proposes countermeasures to these risks by making recommendations that relate to requirements for environmental quality, foods, and crew health on spacecraft and space missions. The AFT portfolio focuses on reducing the mass, volume, and waste of the entire integrated food system to be used in exploration missions, and investigating processing methods to extend the shelf life of food items up to five years, while assuring that exploration crews will have nutritious and palatable foods. The portfolio also delivers improvements in both the food itself and the technologies for storing and preparing it. SHFE sponsors research to establish human factors and habitability standards and guidelines in five risk areas, and provides improved design concepts for advanced crew interfaces and habitability systems. These risk areas include: Incompatible vehicle/habitat design

    Human embryology requires students to understand the simultaneous changes in embryos, but students find it difficult to grasp the concepts presented and to visualise the related processes in three dimensions. The aims of this study have been to develop and evaluate new educational materials and a teaching methodology based on multimedia approaches to improve the comprehension of human development. The materials developed at the State University of Campinas include clinical histories, movies, animations, and ultrasound, as well as autopsy images from embryos and foetuses. The series of embryology lectures were divided into two parts. The first part of the series addressed the development of the body's structures, while in the second part, clinical history and the corresponding materials were shown to the students, who were encouraged to discuss the malformations. The teaching materials were made available on software used by the students in classes. At the end of the discipline, the material and methodology were evaluated with an attitudinal instrument, interviews, and knowledge examination. The response rate to the attitudinal instrument was 95.35%, and the response rate to the interview was 46%. The students approved of the materials and the teaching methodology (reliability of the attitudinal instrument was 0.9057). The exams showed that most students scored above 6.0. A multimedia approach proved useful for solving an important problem associated with teaching methods in many medical institutions: the lack of integration between basic sciences and clinical disciplines.

    Research results have shown that more than half of aviation, aerospace and aeronautics mishaps incidents are attributed to human error. As a part of Quality within space exploration ground processing operations, the identification and or classification of underlying contributors and causes of human error must be identified, in order to manage human error.This presentation will provide a framework and methodology using the Human Error Assessment and Reduction Technique (HEART) and Human Factor Analysis and Classification System (HFACS), as an analysis tool to identify contributing factors, their impact on human error events, and predict the Human Error probabilities (HEPs) of future occurrences. This research methodology was applied (retrospectively) to six (6) NASA ground processing operations scenarios and thirty (30) years of Launch Vehicle related mishap data. This modifiable framework can be used and followed by other space and similar complex operations.

  1. Human factors in the management of the critically ill patient.

    Bion, J F; Abrusci, T; Hibbert, P

    2010-07-01

    Unreliable delivery of best practice care is a major component of medical error. Critically ill patients are particularly susceptible to error and unreliable care. Human factors analysis, widely used in industry, provides insights into how interactions between organizations, tasks, and the individual worker impact on human behaviour and affect systems reliability. We adopt a human factors approach to examine determinants of clinical reliability in the management of critically ill patients. We conducted a narrative review based on a Medline search (1950-March 2010) combining intensive/critical care (units) with medical errors, patient safety, or delivery of healthcare; keyword and Internet search 'human factors' or 'ergonomics'. Critical illness represents a high-risk, complex system spanning speciality and geographical boundaries. Substantial opportunities exist for improving the safety and reliability of care of critically ill patients at the level of the task, the individual healthcare provider, and the organization or system. Task standardization (best practice guidelines) and simplification (bundling or checklists) should be implemented where scientific evidence is strong, or adopted subject to further research ('dynamic standardization'). Technical interventions should be embedded in everyday practice by the adjunctive use of non-technical (behavioural) interventions. These include executive 'adoption' of clinical areas, systematic methods for identifying hazards and reflective learning from error, and a range of techniques for improving teamworking and communication. Human factors analysis provides a useful framework for understanding and rectifying the causes of error and unreliability, particularly in complex systems such as critical care.

    Patient safety is a global challenge that requires knowledge and skills in multiple areas, including human factors and systems engineering. In this chapter, numerous conceptual approaches and methods for analyzing, preventing and mitigating medical errors are described. Given the complexity of healthcare work systems and processes, we emphasize the need for increasing partnerships between the health sciences and human factors and systems engineering to improve patient safety. Those partnerships will be able to develop and implement the system redesigns that are necessary to improve healthcare work systems and processes for patient safety.

    Human factors systems approaches are critical for improving healthcare quality and patient safety. The SEIPS (Systems Engineering Initiative for Patient Safety) model of work system and patient safety is a human factors systems approach that has been successfully applied in healthcare research and practice. Several research and practical applications of the SEIPS model are described. Important implications of the SEIPS model for healthcare system and process redesign are highlighted. Principles for redesigning healthcare systems using the SEIPS model are described. Balancing the work system and encouraging the active and adaptive role of workers are key principles for improving healthcare quality and patient safety. PMID:23845724

    1999-06-30

    The purpose of this report is to present the results and findings of the final Human Factors Engineering (HFE) technical analysis and evaluation of the Cold Vacuum Drying Facility (CVDF). Ergonomics issues are also addressed in this report, as appropriate. This report follows up and completes the preliminary work accomplished and reported by the Preliminary HFE Analysis report (SNF-2825, Spent Nuclear Fuel Project Cold Vacuum Drying Facility Human Factors Engineering Analysis: Results and Findings). This analysis avoids redundancy of effort except for ensuring that previously recommended HFE design changes have not affected other parts of the system. Changes in one part of the system may affect other parts of the system where those changes were not applied. The final HFE analysis and evaluation of the CVDF human-machine interactions (HMI) was expanded to include: the physical work environment, human-computer interface (HCI) including workstation and software, operator tasks, tools, maintainability, communications, staffing, training, and the overall ability of humans to accomplish their responsibilities, as appropriate. Key focal areas for this report are the process bay operations, process water conditioning (PWC) skid, tank room, and Central Control Room operations. These key areas contain the system safety-class components and are the foundation for the human factors design basis of the CVDF.

    Full Text Available This article examines the existing research findings in relation to the research of the factors that are presumably involved in university students’ evaluations of the teaching quality they receive, possibly threatening the validity of the construct. The review is organized around the three implicated sources in the perceptive process of the student, being the student himself, the professor, and the context. The review concludes that, despite some minor effects, the factors under analysis do not represent a substantial threat to the system’s validity. The unproductive debate that has gone on for decades about guarantees in the evaluation of teaching staff has largely been used to cover up the absence of a desire to institutionalize this kind of evaluation system. El presente artículo tiene como objetivo presentar una revisión sobre los hallazgos existentes en relación a la investigación de los factores supuestamente implicados en la valoración que el alumnado universitario realiza sobre la tarea docente de sus profesores, pudiendo suponer una amenaza a la validez de dicho constructo. La revisión se presenta organizada en torno a las tres fuentes implicadas en el proceso perceptivo del alumno, siendo éstas el propio alumno, el profesor y el contexto. La revisión concluye que, a pesar de efectos menores, los factores analizados no representan una amenaza substancial a la validez del sistema. El debate infructuoso que se ha producido durante décadas sobre las garantías en la valoración del personal docente ha sido usado en gran parte para encubrir la falta de deseo de institucionalizar este tipo de sistemas de evaluación.

    A series of human factors evaluations were undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. A team of human factors specialists, assisted by a panel of radiation oncologists, medical physicists, and radiation therapists, conducted site visits to radiation oncology departments at community hospitals, university centers, and free-standing clinics. A function and task analysis was performed initially to guide subsequent evaluations in the areas of workplace environment, system-user interfaces, procedures, training, and organizational practices. To further acquire an in-depth and up-to-date understanding of the practice of teletherapy in support of these evaluations, a systematic literature review was conducted. Factors that have a potential impact on the accuracy of treatment delivery were of primary concern. The present volume is the literature review. The volume starts with an overview of the multiphased nature of teletherapy, and then examines the requirement for precision, the increasing role of quality assurance, current conceptualizations of human error, and the role of system factors such as the workplace environment, user-system interfaces, procedures, training, and organizational practices.

  7. Human factors/ergonomics as a systems discipline? "The human use of human beings" revisited.

    Science.gov (United States)

    Hollnagel, Erik

    2014-01-01

    Discussions of the possible future of Human factors/ergonomics (HFE) usually take the past for granted in the sense that the future of HFE is assumed to be more of the same. This paper argues that the nature of work in the early 2010s is so different from the nature of work when HFE was formulated 60-70 years ago that a critical reassessment of the basis for HFE is needed. If HFE should be a systems discipline, it should be a soft systems rather than a hard systems discipline. It is not enough for HFE to seek to improve performance and well-being through systems design, since any change to the work environment in principle alters the very basis for the change. Instead HFE should try to anticipate how the nature of work will change so that it can both foresee what work will be and propose what work should be.

  8. Comparative genomics of human stem cell factor (SCF

    2017-03-01

    Full Text Available Stem cell factor (SCF is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. In the present study a comparative analysis on nucleotide sequences of SCF was performed in Humanoids using bioinformatics tools including NCBI-BLAST, MEGA6, and JBrowse. Our analysis of nucleotide sequences to find closely evolved organisms with high similarity by NCBI-BLAST tools and MEGA6 showed that human and Chimpanzee (Pan troglodytes were placed into the same cluster. By using JBrowse, we found that SCF in Neanderthal had a single copy number similar to modern human and partly conserved nucleotide sequences. Together, the results approved the gene flow and genetics similarity of SCF among human and P. troglodytes. This may suggest that during evolution, SCF gene transferred partly intact either on the basis of sequence or function from the same ancestors to P. troglodytes, the ancient human like Neanderthal, and then to the modern human.

  9. Revolutions and shifting paradigms in human factors & ergonomics.

    Science.gov (United States)

    Boff, Kenneth R

    2006-07-01

    The "Revolution in Information Technology" has spawned a series of transformational revolutions in the nature and practice of human factors and ergonomics (HFE). "Generation 1" HFE evolved with a focus on adapting equipment, workplace and tasks to human capabilities and limitations. Generation 2, focused on cognitive systems integration, arose in response to the need to manage automation and dynamic function allocation. Generation 3 is focused on symbiotic technologies that can amplify human physical and cognitive capabilities. Generation 4 is emergent and is focused on biological enhancement of physical or cognitive capabilities. The shift from HFE Generations 1 and 2 to Generations 3 and 4 profoundly alters accepted boundary constraints on the adaptability of humans in complex systems design. Furthermore, it has opened an ethical divide between those that see cognitive and physical enhancement as a great benefit to society and those who perceive this as tampering with the fundamentals of human nature.

    Background Does klotho (KL) protein exist in human serum, and is there any correlation between KL protein in serum with human aging? In order to answer those questions, we identified KL protein in human serum and established the correlation between KL protein in human serum and aging.Methods We prepared a polyclonal antibody against human KL protein that was able to recognize the C-terminal of human secreted KL protein. Western blot and enzyme-linked immunosorbent assay (ELISA) were used to identify KL protein in human serum.Results In Western blot, the antibody specifically recognized a 60-kD KL protein in both human and mice serum. The population aged from 0 to 91 years screened by ELISA revealed that the level of serum KL declined while age increased, though each individual level was variable and that the trend of decreasing in serum KL had no difference in sex.Conclusion Our data suggest that KL is a serum factor related to human aging.

    Moore, Dave; Barnard, Tim

    2012-12-01

    This article is based on a keynote presentation given at the 18th Congress of the International Ergonomics Association in Recife, Brazil, February 2012. It considers new, and not so new, approaches and practical roles for the emerging field of human factors/ergonomics (HFE) in sustainable development (SD).The material for this article was largely drawn from the literature in the fields of human development, sustainability, climate change mitigation and adaptation, and social/environmental impact assessment. Identifying the role of HFE in SD is not a simple one and from the outset is complicated by the widely differing ideas in the sustainability literature about what exactly it is we are hoping to sustain. Is it individual companies, business models, cultures, or the carrying capacity of our planet? Or combinations of these? For the purposes of this article, certain assumptions are made, and various emerging opportunities and responsibilities associated with our changing world of work are introduced. First, there are new versions of traditional tasks for us, such as working with the people and companies in the renewable energy sectors. Beyond this, however, it is suggested that there are emerging roles for HFE professionals in transdisciplinary work where we might play our part, for example, in tackling the twinned issues of climate change and human development in areas of significant poverty. In particular we have the tools and capabilities to help define and measure what groups have reason to value, and wish to sustain. It is suggested, that to do this effectively, however, will require a philosophical shift, or perhaps just a philosophical restatement at a collective level, regarding who and what we ultimately serve.

    Animals have been used in research and teaching for a long time. However, clear ethical guidelines and pertinent legislation were instated only in the past few decades, even in developed countries with Judeo-Christian ethical roots. We compactly cover the basics of animal research ethics, ethical reviewing and compliance guidelines for animal experimentation across the developed world, "our" fundamentals of institutional animal research ethics teaching, and emerging alternatives to animal research. This treatise was meticulously constructed for scientists interested/involved in animal research. Herein, we discuss key animal ethics principles - Replacement/Reduction/Refinement. Despite similar undergirding principles across developed countries, ethical reviewing and compliance guidelines for animal experimentation vary. The chronology and evolution of mandatory institutional ethical reviewing of animal experimentation (in its pioneering nations) are summarised. This is followed by a concise rendition of the fundamentals of teaching animal research ethics in institutions. With the advent of newer methodologies in human cell-culturing, novel/emerging methods aim to minimise, if not avoid the usage of animals in experimentation. Relevant to this, we discuss key extant/emerging alternatives to animal use in research; including organs on chips, human-derived three-dimensional tissue models, human blood derivates, microdosing, and computer modelling of various hues. © 2017 The Authors.

    Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this shift. Yet, essential clinical skills, professionalism, and humanistic patient interactions are best taught at the bedside. Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this decline. This study explored perceptions of teachers and learners on the value of bedside teaching and the humanistic dimensions of bedside interactions that make it imperative to shift clinical teaching back to the bedside. Focus group methodology was used to explore teacher and learner opinions. Four teacher groups consisted of (a) Chief Residents, (b) Residency Program Directors, (c) skilled bedside teachers, and (d) a convenience group of other Department of Medicine faculty at Boston University School of Medicine. Six learner groups consisted 2 each of 3rd-year students, PGY1 medicine residents, and PGY2 medicine residents. Each discussion lasted 60 to 90 minutes. Sessions were audiotaped, transcribed, and analyzed using qualitative methods. Teachers and learners shared several opinions on bedside teaching, particularly around humanistic aspects of bedside interactions. The key themes that emerged included (a) patient involvement in discussions, (b) teachers as role models of humanism, (c) preserving learner autonomy, (d) direct observation and feedback of learners at the bedside, (e) interactions with challenging patients, and (e) admitting limitations. Within these themes, participants noted some behaviors best avoided at the bedside. Teachers and learners regard the bedside as a valuable venue in which to learn core values of medicine. They proposed many strategies to preserve these humanistic values and improve bedside teaching. These strategies are essential for true patient-centered care.

  15. Teaching Progress: A Critique of the Grand Narrative of Human Rights as Pedagogy for Marginalized Students

    Directory of Open Access Journals (Sweden)

    Robyn Linde

    2015-10-01

    Full Text Available With the adoption of the Universal Declaration of Human Rights in 1948, education about human rights became an important focus of the new human rights regime and a core method of spreading its values throughout the world. This story of human rights is consistently presented as a progressive teleology that contextualizes the expansion of rights within a larger grand narrative of liberalization, emancipation, and social justice. This paper examines the disjuncture between the grand narrative on international movements for human rights and social justice and the lived experiences of marginalized students in urban environments in the United States. Drawing on our experience as professors who teach human rights, social justice, and social movements courses at an urban, four-year college in Providence, R.I., with a student body which includes large populations of students who are of color, first-generation, economically disadvantaged, and nontraditional in other ways, we explore the relevance and impact of these grand narratives for the lives of our students and their sense of agency. In particular, we advocate for a critical and transformational approach to human rights pedagogy to counter and overcome the pervasive individualization that undergirds the grand narrative of human rights. We argue that a critical (and radical human rights pedagogy must evaluate the position of the individual in modern life if liberation through human rights law and activism is to be possible.

    2013-03-01

    Full Text Available Learning interventions and new technologies that aim to improve human performance must take cognisance of industry factors inhibiting human performance. The dynamic and fast pace nature of the Information and Communication Technologies (ICT and the engineering industries do not lend themselves to proper skills planning and management. These industries experience real skills gaps, to some of which they contribute by themselves. This study reports on these performance-inhibiting factors such as the underutilisation of available skills, tolerance for individual preferences, and dynamically, and informally refining a role objective while an employee is occupying a certain role. The important professional skills required by individuals to cope with these real life factors are also explored in the skills gaps management context. Moreover, these industries need a profile they refer to as Special Forces, which denotes a high calibre of worker that possesses well-developed professional skills whilst having advanced technical expertise and sufficient experience. This resource profile is required largely due to the poor management of human resource processes in practice and the current reported lack of adequate skills. Furthermore, this study refers to the recent lack of a working definition for these Special Forces leading to the omitted active development of these profiles in industry today, which appears to become a key human performance inhibiting factor.

    Full Text Available With the constant increasing in technology and education, with development of multinational corporations and frequent changes in economic status and structures, Human Resources become the most crucial, the most reliable and necessary department. Moreover, in many companies, Human Resource Department is the most important department. The main purpose of this research is to mark off top rated factors related with Human Resource Management by analyzing all the abstracts of the published papers of a Human Resource Management journal for the period between the first issue of 2005 and the first issue of 2013. We identified the most frequent categories of the articles during this analyzed period. The literature is reviewed according to the identified factors related to Human Resource Management. If the keywords about Human Resources (35,7 % is not considered, it is observed that the researches, for the selected period, have organizational approach (39,2 % (Management, organizational strategy, organizational performance, organizational culture, contextual issues, technical issues and location and from the individual approach (24,4 % (Individual performance, training and education, employee rights, and behavioral issues. Furthermore, it is also observed that the researchers (a mainly give importance to the practice more than the theory and (b consider the organization more than the individual.

    Seeing is critical to human performance. Lighting is critical for seeing. Therefore, lighting is critical to human performance. This is common sense, and here on earth, it is easily taken for granted. However, on orbit, because the sun will rise or set every 45 minutes on average, humans working in space must cope with extremely dynamic lighting conditions. Contrast conditions of harsh shadowing and glare is also severe. The prediction of lighting conditions for critical operations is essential. Crew training can factor lighting into the lesson plans when necessary. Mission planners can determine whether low-light video cameras are required or whether additional luminaires need to be flown. The optimization of the quantity and quality of light is needed because of the effects on crew safety, on electrical power and on equipment maintainability. To address all of these issues, an illumination modeling system has been developed by the Graphics Research and Analyses Facility (GRAF) and Lighting Environment Test Facility (LETF) in the Space Human Factors Laboratory at NASA Johnson Space Center. The system uses physically based ray tracing software (Radiance) developed at Lawrence Berkeley Laboratories, a human factors oriented geometric modeling system (PLAID) and an extensive database of humans and environments. Material reflectivity properties of major surfaces and critical surfaces are measured using a gonio-reflectometer. Luminaires (lights) are measured for beam spread distribution, color and intensity. Video camera performances are measured for color and light sensitivity. 3D geometric models of humans and the environment are combined with the material and light models to form a system capable of predicting lighting conditions and visibility conditions in space.

    The threat posed by large carnivores to livestock and humans makes peaceful coexistence between them difficult. Effective implementation of conservation laws and policies depends on the attitudes of local residents toward the target species. There are many known correlates of human attitudes toward carnivores, but they have only been assessed at the scale of the individual. Because human societies are organized hierarchically, attitudes are presumably influenced by different factors at different scales of social organization, but this scale dependence has not been examined. We used structured interview surveys to quantitatively assess the attitudes of a Buddhist pastoral community toward snow leopards (Panthera uncia) and wolves (Canis lupus). We interviewed 381 individuals from 24 villages within 6 study sites across the high-elevation Spiti Valley in the Indian Trans-Himalaya. We gathered information on key explanatory variables that together captured variation in individual and village-level socioeconomic factors. We used hierarchical linear models to examine how the effect of these factors on human attitudes changed with the scale of analysis from the individual to the community. Factors significant at the individual level were gender, education, and age of the respondent (for wolves and snow leopards), number of income sources in the family (wolves), agricultural production, and large-bodied livestock holdings (snow leopards). At the community level, the significant factors included the number of smaller-bodied herded livestock killed by wolves and mean agricultural production (wolves) and village size and large livestock holdings (snow leopards). Our results show that scaling up from the individual to higher levels of social organization can highlight important factors that influence attitudes of people toward wildlife and toward formal conservation efforts in general. Such scale-specific information can help managers apply conservation measures at

    Full Text Available This article explores the degree to which student collaborations on research and writing assignments can effectively realize learning outcomes. The assignment, in this case, encouraged students to contribute discrete parts of a research project in order to develop their complementary abilities: researching, consulting, drafting, and revising. The outcomes for students included appreciation for their individual expertise, and experience combining discrete contributions into a result that surpasses the sum of its parts. In the course, we gave students preliminary guidance for establishing team objectives and roles for the duration of this assignment and asked them to evaluate their learning experience at the end. In this paper, we analyze the students’ quantitative and qualitative feedback, and suggest ways to structure and supervise collaborative assignments so that students develop their expertise and complementary skills. We suggest that collaborative work such as this is essential for advanced undergraduates in the humanities, where collaborations are less common than in other disciplines. Moreover, we conclude that future humanities instructors should be open to the benefits of collaborative research and writing. This article will be of interest to instructors who wish to develop collaborative assignments that improve students’ disciplinary expertise, engagement with course materials, and outreach to audiences beyond the academy. Cet article explore la mesure dans laquelle le travail en collaboration des étudiants en matière de recherche et de rédaction de devoirs peut aboutir à des résultats d’apprentissage efficaces.

    Nuclear installations are socio technical systems where human and organizational factors, in both utilities and regulators, have a significant impact on safety. Three Mile Island (TMI) accident, original of several initiatives in the human factors field, nevertheless became a lost opportunity to timely acquire lessons related to the upper tiers of the system. Nowadays, Spanish nuclear installations have integrated in their processes specialists and activities in human and organizational factors, promoted by the licensees After many years of hard work, Spanish installations have achieved a better position to face new challenges, such as those posed by Fukushima. With this experience, only technology-centered action plan would not be acceptable, turning this accident in yet another lost opportunity. (Author)

    New human factors issues, such as evaluation of information navigation, the consideration of operator characteristics, and operator performance assessment, related to the HMI design based on VDUs are being risen. Thus, in order to solve these human factors issues, this project aims to establish the experimental technologies including the techniques for experimental design, experimental measurement, data collection and analysis, and to develop ITF (Integrated Test Facility) suitable for the experiment of HMI design evaluation. For the establish of the experimental data analysis and evaluation methodologies, we developed as the following: (1) a paradigm for human factors experimentation including experimental designs, procedures, and data analysis. (2) the methods for the assessment of operator`s mental workload (3) DAEXESS (data analysis and experiment evaluation supporting system). Also, we have established a experiment execution technologies through the preliminary experiments, such as the suitability evaluation of information display on a LSDP, the evaluation of information display on a LSDP, the evaluation of computerized operation procedure and an experiment of advanced alarm system (ADIOS). Finally, we developed the ITF including human machine simulator, telemetry system, an eye tracking system, an audio/video data measurement system, and three dimensional micro behaviour analysis system.

    Smaller and multi-modular reactor (MMR) will be highly technologically-advanced systems allowing more system flexibility to reactors configurations (e.g., addition/deletion of reactor units). While the technical and financial advantages of systems may be numerous, MMR presents many human factors challenges that may pose vulnerability to plant safety. An important human factors challenge in MMR operation and performance is the monitoring of data from multiple plants from centralized control rooms where human operators are responsible for interpreting, assessing, and responding to different system’s states and failures (e.g., simultaneously monitoring refueling at one plant while keeping an eye on another plant’s normal operating state). Furthermore, the operational, safety, and performance requirements for MMR can seriously change current staffing models and roles, the mode in which information is displayed, procedures and training to support and guide operators, and risk analysis. For these reasons, addressing human factors concerns in MMR are essential in reducing plant risk.

    1995-03-01

    This technical report was produced to assist the preparers and reviewers of the human factors portions of the SAR in completing their assigned tasks regarding analysis and/or review of completed analyses. The checklists, which are the main body of the report, and the subsequent tables, were developed to assist analysts in generating the needed analysis data to complete the human engineering analysis for the SAR. The technical report provides a series of 19 human factors engineering (HFE) checklists which support the safety analyses of the US Department of Energy`s (DOE) reactor and nonreactor facilities and activities. The results generated using these checklists and in the preparation of the concluding analyses provide the technical basis for preparing the human factors chapter, and subsequent inputs to other chapters, required by DOE as a part of the safety analysis reports (SARs). This document is divided into four main sections. The first part explains the origin of the checklists, the sources utilized, and other information pertaining to the purpose and scope of the report. The second part, subdivided into 19 sections, is the checklists themselves. The third section is the glossary which defines terms that could either be unfamiliar or have specific meanings within the context of these checklists. The final section is the subject index in which the glossary terms are referenced back to the specific checklist and page the term is encountered.

    Since the space era began, we learned first to survive and then to live in space. In the state of the art, we know how important human factors research and development is to guarantee maximum safety and performance for human missions. With the extension of the duration of space missions, we also need to learn how habitability and comfort factors are closely related to safety and performance. Humanities disciplines such as design, architecture, anthropometry, and anthropology are now involved in mission design from the start. Actual plans for building a simulated Moon village in order to simulate and test Moon missions are now being carried out using a holistic approach, involving multidisciplinary experts cooperating concurrently with regard to the interactions among humans, technology, and the environment. However, in order to implement such plans, we need basic anthropometrical data, which is still missing. In other words: to optimize performance, we need to create doors and ceilings with dimensions that support a natural human movement in the reduced gravity environment of the Moon, but we are lacking detailed anthropometrical data on human movement on the Moon. In the Apollo missions more than 50 years ago, no anthropometrical studies were carried in hypogravity out as far as we know. The necessity to collect data is very consistent with state-of-the-art research. We still have little knowledge of how people will interact with the Moon environment. Specifically, it is not known exactly which posture, which kind of walking and running motions astronauts will use both inside and outside a Moon station. Considering recent plans for a Moon mission where humans will spend extensive time in reduced gravity conditions, the need for anthropometric, biomechanics and kinematics field data is a priority in order to be able to design the right architecture, infrastructure, and interfaces. Objective of this paper: Bring knowledge on the relevance of anthropometrical and

    My first encounter with human factors happened in early 1973: I was performing a reliability assessment of the safety injection system of the Fessenheim reactor, and I found that the operators had to switch to the recirculation phase manually and had only 6 min between the low and low-low level alarm indicating that the water tank was empty. It of course led us to replace this manual action by an automatic positioning for the recirculation phase. In July of the same year, I attended a North Atlantic Treaty Organization workshop in Liverpool on reliability assessment, and I met Alan Swain from the United States and Jens Rasmussen from Denmark. During the long rainy evenings of the seminar, we had time to discuss human errors and human factors, and that was the beginning of a very fruitful collaboration between us. I realized then the complexity of the problem. Quantification needs were obvious for reliability and risk assessment studies, but, at the same time, there were needs for better understanding of human behavior and the mechanisms that could lead to human errors. Knowledge of the man-machine interface also seemed very poor, although some basic ergonomic rules were available and could be applied. But a major problem was the lack of data.

    Regulatory factor binding to genomic DNA protects the underlying sequence from cleavage by DNase I, leaving nucleotide-resolution footprints. Using genomic DNase I footprinting across 41 diverse cell and tissue types, we detected 45 million transcription factor occupancy events within regulatory regions, representing differential binding to 8.4 million distinct short sequence elements. Here we show that this small genomic sequence compartment, roughly twice the size of the exome, encodes an expansive repertoire of conserved recognition sequences for DNA-binding proteins that nearly doubles the size of the human cis-regulatory lexicon. We find that genetic variants affecting allelic chromatin states are concentrated in footprints, and that these elements are preferentially sheltered from DNA methylation. High-resolution DNase I cleavage patterns mirror nucleotide-level evolutionary conservation and track the crystallographic topography of protein-DNA interfaces, indicating that transcription factor structure has been evolutionarily imprinted on the human genome sequence. We identify a stereotyped 50-base-pair footprint that precisely defines the site of transcript origination within thousands of human promoters. Finally, we describe a large collection of novel regulatory factor recognition motifs that are highly conserved in both sequence and function, and exhibit cell-selective occupancy patterns that closely parallel major regulators of development, differentiation and pluripotency.

    The human cytomegalovirus (HCMV) IE86 Cdna was cloned into Pgex-2T and fusion protein GST-IE86 was expressed in E. Coli. SDS-PAGE and Western blot assay indicated that fusion protein GST-IE86 with molecular weight of 92 ku is soluble in the supernatant of cell lysate. Protein GST and fusion protein GST-IE86 were purified by affinity chromatography. The technology of co-separation and specific affinity chromatography was used to study the interactions of HCMV IE86 protein with some transcriptional regulatory proteins and transcriptional factors. The results indicated that IE86 interacts separately with transcriptional factor TFIIB and promoter DNA binding transcription trans-activating factors SP1, AP1 and AP2 to form a heterogenous protein complex. These transcriptional trans-activating factors, transcriptional factor and IE86 protein were adsorbed and retained in the affinity chromatography simultaneously. But IE86 protein could not interact with NF-Кb, suggesting that the function of IE86 protein that can interact with transcriptional factor and transcriptional trans-activating factors has no relevance to protein glycosylation. IE86 protein probably has two domains responsible for binding transcriptional trans-activating regulatory proteins and transcriptional factors respectively, thus activating the transcription of many genes. The interactions accelerated the assembly of the transcriptional initiation complexes.

    Joint arthrodesis utilizing autogenous bone graft remains the gold standard of treatment in fusion procedures of the foot and ankle. Graft harvest, however, has been associated with increased morbidity to patients as well as increased costs. With this in mind, multiple clinical studies have evaluated the efficacy of recombinant human platelet-derived growth factor (rh-PDGF-BB) with beta-tricalcium phosphate (B-TCP) to augment in foot and ankle arthrodesis with favorable results. These factors have led to the increased use of rh-PDGF-BB with B-TCP in Vancouver with good clinical results. Copyright © 2016 Elsevier Inc. All rights reserved.

    2012-01-01

    For human factors (HF) to avoid being considered of "side-car" status, it needs to be positioned within the organization in such a way that it affects business strategies and their implementation. Tools are needed to support this effort. This paper explores the feasibility of applying a technique from operational research called cognitive mapping to link HF to corporate strategy. Using a single case study, a cognitive map is drawn to reveal the complex relationships between human factors and achieving an organization's strategic goals. Analysis of the map for central concepts and reinforcing loops enhances understanding that can lead to discrete initiatives to facilitate integration of HF. It is recommended that this technique be used with senior managers to understand the organizations` strategic goals and enhance understanding of the potential for HF to contribute to the strategic goals.

    Although the proteins that read the gene regulatory code, transcription factors (TFs), have been largely identified, it is not well known which sequences TFs can recognize. We have analyzed the sequence-specific binding of human TFs using high-throughput SELEX and ChIP sequencing. A total of 830 binding profiles were obtained, describing 239 distinctly different binding specificities. The models represent the majority of human TFs, approximately doubling the coverage compared to existing systematic studies. Our results reveal additional specificity determinants for a large number of factors for which a partial specificity was known, including a commonly observed A- or T-rich stretch that flanks the core motifs. Global analysis of the data revealed that homodimer orientation and spacing preferences, and base-stacking interactions, have a larger role in TF-DNA binding than previously appreciated. We further describe a binding model incorporating these features that is required to understand binding of TFs to DNA.

    Energy Technology Data Exchange (ETDEWEB)

    Ryan, T.G.

    1995-10-01

    A workshop was conducted whose specific purpose was to build on earlier work of the United States National Research Council, United States Federal government agencies, and the larger human factors community to: (1) clarify human factors issues pertaining to degraded performance in advanced human-machine systems (e.g., nuclear production, transportation, aerospace) due to human work underload and workload transition, and (2) develop strategies for resolving these issues. Recent history demonstrates that: (1) humans often react adversely to their diminishing roles in advanced human-machine systems, and therefore (2) new allocation models and strategies are required if humans are to be willing and able to assume diminishing and shifting roles assigned to them in these systems, and are to accept new technologies making up these systems. Problems associated with theses diminishing and shifting human roles are characterized as work underload and workload transitions. The workshop affirmed that: (1) work underload and workload transition are issues that will have to be addressed by designers of advanced human-machine systems, especially those relying on automation, if cost, performance, safety, and operator acceptability are to be optimized, (2) human machine allocation models, standards, and guidelines which go beyond simple capability approaches will be needed to preclude or seriously diminish the work underload and workload transition problems, and (3) the 16 workload definition, measurement, situational awareness, and trust issues identified during the workshop, need resolution if these models, standards, and guidelines are to be achieved.

    The paper describes a method for purification of human platelet-derived growth factor (PDGF) from outdated platelet-rich plasma (PRP) using commonly available laboratory reagents and yielding a mitogen purified 800,000-fold over the starting material. (/sup 3/H)thymidine incorporation into DNA of cultured cells responsive to PDGF represents the most readily available method to follow its purification and define the biological activity of a purified preparation. Other assays to quantitate PDGF include radioreceptor assay and radioimmunoassay.

    1980-06-01

    The purpose of this document is to provide an overview of the recommended activities and methods to be employed by a team of human factors engineers during the development of a nuclear waste retrieval system. This system, as it is presently conceptualized, is intended to be used for the removal of storage canisters (each canister containing a spent fuel rod assembly) located in an underground salt bed depository. This document, and the others in this series, have been developed for the purpose of implementing human factors engineering principles during the design and construction of the retrieval system facilities and equipment. The methodology presented has been structured around a basic systems development effort involving preliminary development, equipment development, personnel subsystem development, and operational test and evaluation. Within each of these phases, the recommended activities of the human engineering team have been stated, along with descriptions of the human factors engineering design techniques applicable to the specific design issues. Explicit examples of how the techniques might be used in the analysis of human tasks and equipment required in the removal of spent fuel canisters have been provided. Only those techniques having possible relevance to the design of the waste retrieval system have been reviewed. This document is intended to provide the framework for integrating human engineering with the rest of the system development effort. The activities and methodologies reviewed in this document have been discussed in the general order in which they will occur, although the time frame (the total duration of the development program in years and months) in which they should be performed has not been discussed.

  19. What does Pirahã grammar have to teach us about human language and the mind?

    Everett, Daniel L

    2012-11-01

    Pirahã is a language isolate of the Brazilian Amazon. Among the lessons it has to teach us about human language and the mind, two are highlighted here. The first is that recursion is not a necessary condition for human syntax, because there is no evidence for recursive sentential syntax in the language. This is a stark counterexample to the claims of Chomsky and others. The second lesson is that the influence of culture on Pirahã grammar, coupled with much established and newer research, indicates that the idea of an innate, universal grammar has little if any role to play in our understanding of the nature, origins, and use of human language.

    Transforming growth factor (TGF)-{alpha} and epidermal growth factor (EGF) were measured in human milk by means of homologous radioimmunoassay. As previously reported, EGF concentration in the colostrum was approximately 200 ng/ml and decreased to 50 ng/ml by day 7 postpartum. The value of immunoreactive (IR)-TGF-{alpha} was 2.2-7.2 ng/ml, much lower than that of EGF. In contrast to EGF, the concentration of IR-TGF-{alpha} was fairly stable during the 7 postpartum days. There was no relationship between the concentrations of IR-TGF-{alpha} and IR-EGF, suggesting that the regulatory mechanism in the release of the two growth factors is different. On gel-chromatography using a Sephadex G-50 column, IR-EGF appeared in the fraction corresponding to that of authentic human EGF, while 70%-80% of the IR-TGF-{alpha} was eluted as a species with a molecular weight greater than that of authentic human TGF-{alpha}. Although the physiological role of TGF-{alpha} in milk is not known, it is possible that it is involved in the development of the mammary gland and/or the growth of newborn infants.

    during aircraft maintenance. In the EASA approved aircraft maintenance organisation, which includes in its working system the human factor as well, the tendency is to apply the approach by continuous monitoring and analysis of errors in aircraft maintenance. Such approach achieves advance prevention or reduction of the occurrence of harmful events, such as accidents, incidents, injuries and in a wider sense damages related to aircraft operation and maintenance. The research presented in this paper is a result of gathering and systematization of errors caused by human factors over the last five years in one organisation for aircraft maintenance certified according to the European standards. The study encompasses an analysis of 28 (twenty-eight investigations of individual cases and provides insight into the main factors of errors. The results of analyses on the cause of occurrence of human error show similar results like the Boeing study which was carried out for the world fleet.

    A continuing high number of patients suffer harm from medical treatment. In 60-70% of the cases the sources of harm can be attributed to the field of human factors (HFs) and teamwork; nevertheless, those topics are still neither part of medical education nor of basic and advanced training even though it has been known for many years and it has meanwhile also been demonstrated for surgical specialties that training in human factors and teamwork considerably reduces surgical mortality.Besides the medical field, the concept of crisis resource management (CRM) has already proven its worth in many other industries by improving teamwork and reducing errors in the domain of human factors. One of the best ways to learn about CRM and HFs is realistic simulation team training with well-trained instructors in CRM and HF. The educational concept of the HOTT (hand over team training) courses for trauma room training offered by the DGU integrates these elements based on the current state of science. It is time to establish such training for all medical teams in emergency medicine and operative care. Accompanying safety measures, such as the development of a positive culture of safety in every department and the use of effective critical incident reporting systems (CIRs) should be pursued.

    Full Text Available Necrotizing enterocolitis (NEC is a devastating condition of premature infants that results from the gut microbiome invading immature intestinal tissues. This results in a life-threatening disease that is frequently treated with the surgical removal of diseased and dead tissues. Epidermal growth factor (EGF, typically found in bodily fluids, such as amniotic fluid, salvia and mother's breast milk, is an intestinotrophic growth factor and may reduce the onset of NEC in premature infants. We have produced human EGF in soybean seeds to levels biologically relevant and demonstrated its comparable activity to commercially available EGF. Transgenic soybean seeds expressing a seed-specific codon optimized gene encoding of the human EGF protein with an added ER signal tag at the N' terminal were produced. Seven independent lines were grown to homozygous and found to accumulate a range of 6.7 +/- 3.1 to 129.0 +/- 36.7 μg EGF/g of dry soybean seed. Proteomic and immunoblot analysis indicates that the inserted EGF is the same as the human EGF protein. Phosphorylation and immunohistochemical assays on the EGF receptor in HeLa cells indicate the EGF protein produced in soybean seed is bioactive and comparable to commercially available human EGF. This work demonstrates the feasibility of using soybean seeds as a biofactory to produce therapeutic agents in a soymilk delivery platform.

    β-Cell dysfunction in type 1 and type 2 diabetes is accompanied by a progressive loss of β-cells, and an understanding of the cellular mechanism(s) that regulate β-cell mass will enable approaches to enhance hormone secretion. It is becoming increasingly recognized that enhancement of human β-cell proliferation is one potential approach to restore β-cell mass to prevent and/or cure type 1 and type 2 diabetes. While several reports describe the factor(s) that enhance β-cell replication in animal models or cell lines, promoting effective human β-cell proliferation continues to be a challenge in the field. In this review, we discuss recent studies reporting successful human β-cell proliferation including WS6, an IkB kinase and EBP1 inhibitor; harmine and 5-IT, both DYRK1A inhibitors; GNF7156 and GNF4877, GSK-3β and DYRK1A inhibitors; osteoprotegrin and Denosmab, receptor activator of NF-kB (RANK) inhibitors; and SerpinB1, a protease inhibitor. These studies provide important examples of proteins and pathways that may prove useful for designing therapeutic strategies to counter the different forms of human diabetes.

    This project aims to identify poor human factors design decisions that led to error-prone systems, or did not facilitate the flight crew making the right choices; and to verify that NASA is effectively preventing similar incidents from occurring again. This analysis was performed by reviewing significant incidents and close calls in human spaceflight identified by the NASA Johnson Space Center Safety and Mission Assurance Flight Safety Office. The review of incidents shows whether the identified human errors were due to the operational phase (flight crew and ground control) or if they initiated at the design phase (includes manufacturing and test). This classification was performed with the aid of the NASA Human Systems Integration domains. This in-depth analysis resulted in a tool that helps with the human factors classification of significant incidents and close calls in human spaceflight, which can be used to identify human errors at the operational level, and how they were or should be minimized. Current governing documents on human systems integration for both government and commercial crew were reviewed to see if current requirements, processes, training, and standard operating procedures protect the crew and ground control against these issues occurring in the future. Based on the findings, recommendations to target those areas are provided.

    The spatial position and distribution of human body meridian are expressed limitedly in the decision support system (DSS) of acupuncture and moxibustion at present, which leads to the failure to give the effective quantitative analysis on the spatial range and the difficulty for the decision-maker to provide a realistic spatial decision environment. Focusing on the limit spatial expression in DSS of acupuncture and moxibustion, it was proposed that on the basis of the geographic information system, in association of DSS technology, the design idea was developed on the human body meridian spatial DSS. With the 4-layer service-oriented architecture adopted, the data center integrated development platform was taken as the system development environment. The hierarchical organization was done for the spatial data of human body meridian via the directory tree. The structured query language (SQL) server was used to achieve the unified management of spatial data and attribute data. The technologies of architecture, configuration and plug-in development model were integrated to achieve the data inquiry, buffer analysis and program evaluation of the human body meridian spatial DSS. The research results show that the human body meridian spatial DSS could reflect realistically the spatial characteristics of the spatial position and distribution of human body meridian and met the constantly changeable demand of users. It has the powerful spatial analysis function and assists with the scientific decision in clinical treatment and teaching of acupuncture and moxibustion. It is the new attempt to the informatization research of human body meridian.

    Quantitative Risk Analyses (QRAs) are one of the main tools for risk management within the Norwegian and UK oil and gas industry. Much criticism has been given to the limitations related to the QRA-models and that the QRAs do not include human and organizational factors (HOF-factors). Norway and UK offshore legislation and guidelines require that the HOF-factors are included in the QRAs. A study of 15 QRAs shows that the factors are to some extent included, and there are large differences between the QRAs. The QRAs are categorized into four levels according to the findings. Level 1 QRAs do not describe or comment on the HOF-factors at all. Relevant research projects have been conducted to fulfill the requirements of Level 3 analyses. At this level, there is a systematic collection of data related to HOF. The methods are systematic and documented, and the QRAs are adjusted. None of the QRAs fulfill the Level 4 requirements. Level 4 QRAs include the model and describe the HOF-factors as well as explain how the results should be followed up in the overall risk management. Safety audits by regulatory authorities are probably necessary to point out the direction for QRA and speed up the development.

    Healthcare employee satisfaction is an important criterion for the efficiency of human resource management and prognostic impact factor for high turnover of staff. Furthermore, job satisfaction positively affects patient satisfaction, which is an important indicator for quality of care. The goal of our study was to identify factors associated with job satisfaction in healthcare organizations in Ukraine. We conducted sociological and psychological survey of 190 healthcare professionals (81% response rate) in Kherson City Hospital. Job satisfaction and organizational climate was assessed through developed questionnaire, "Test Motype" method of Gerchikov (motivational profile designing) and "Diagnosis Syndrome emotional burnout" method of Boyko. Spearman rank correlation was used for analysis. Job satisfaction positively correlated with personnel age and time record, career prospects, professional development, superior-subordinate, peer-to-peer and patient communications (psatisfaction did not correlate with responsibility of executives, factors for satisfaction of job description, working conditions and range of wages (all p> 0.05). Based on findings we developed dual job satisfaction-dissatisfaction approach specific for healthcare employee in Ukraine. This model includes internal factors such as work experience, career prospects, professional motivation; external factors such as leadership, governance, work environment, customer satisfaction and preventive factors such as staff role, job description, company policies, salary and benefits.

    Factor VIII is a procofactor that plays a critical role in blood coagulation, and is missing or defective in hemophilia A. We determined the X-ray crystal structure of B domain-deleted human factor VIII. This protein is composed of five globular domains and contains one Ca{sup 2+} and two Cu{sup 2+} ions. The three homologous A domains form a triangular heterotrimer where the A1 and A3 domains serve as the base and interact with the C2 and C1 domains, respectively. The structurally homologous C1 and C2 domains reveal membrane binding features. Based on biochemical studies, a model of the factor IXa-factor VIIIa complex was constructed by in silico docking. Factor IXa wraps across the side of factor VIII, and an extended interface spans the factor VIII heavy and light chains. This model provides insight into the activation of factor VIII and the interaction of factor VIIIa with factor IXa on the membrane surface.

Analysis of the responses revealed the participation of teaching assistants in a large percentage of classes and the use of teaching resources, particularly images, from conventional radiographs to magnetic resonance images. The number of classes for cadaver dissection and the number of students with access to that type of class were small. In most cases, dissection was performed according to anatomic regions or systems. Medicine and nursing students had the highest number of practical dissection classes. Most students were assessed using practical and theoretical tests. Findings revealed conditions similar to those found elsewhere. Resources should be renewed and used to improve teaching for students whose courses demand the study of human anatomy.

    2008-07-01

    Full Text Available Higher education institutions in South Africa have undergone a number of changes over the past few years. These changes brought about inter alia changed work environments and job demands. One of the new job demands is the need to incorporate technology in teaching and learning, viz. e-learning. Not all job incumbents, however, adapted successfully to these changes, particularly with regard to e-readiness. Such a lack in e-readiness is likely to influence the effectiveness with which an academic employee will fulfil his/her online learning duties. Therefore, it is important to find solutions to overcome the lack of e-readiness. This article will focus on the role of human resource appraisal, in order to assess the e-readiness of online learning facilitators with a view to improving their online skills and capacity. A number of human factors that can play a role in employee performance and motivation, namely learning styles, personal profile patterns, and pace and style of technology adoption will be briefly outlined, in order to determine the role that these factors could play in assessing the e-readiness of online learning facilitators.

  17. Workforce scheduling: A new model incorporating human factors

    2012-12-01

    Full Text Available Purpose: The majority of a company’s improvement comes when the right workers with the right skills, behaviors and capacities are deployed appropriately throughout a company. This paper considers a workforce scheduling model including human aspects such as skills, training, workers’ personalities, workers’ breaks and workers’ fatigue and recovery levels. This model helps to minimize the hiring, firing, training and overtime costs, minimize the number of fired workers with high performance, minimize the break time and minimize the average worker’s fatigue level.Design/methodology/approach: To achieve this objective, a multi objective mixed integer programming model is developed to determine the amount of hiring, firing, training and overtime for each worker type.Findings: The results indicate that the worker differences should be considered in workforce scheduling to generate realistic plans with minimum costs. This paper also investigates the effects of human fatigue and recovery on the performance of the production systems.Research limitations/implications: In this research, there are some assumptions that might affect the accuracy of the model such as the assumption of certainty of the demand in each period, and the linearity function of Fatigue accumulation and recovery curves. These assumptions can be relaxed in future work.Originality/value: In this research, a new model for integrating workers’ differences with workforce scheduling is proposed. To the authors' knowledge, it is the first time to study the effects of different important human factors such as human personality, skills and fatigue and recovery in the workforce scheduling process. This research shows that considering both technical and human factors together can reduce the costs in manufacturing systems and ensure the safety of the workers.

    Ramasharma, K.; Li, C.H.

    1987-05-01

    Human granulosa cells cultured with calf serum actively proliferated for 18-20 generations and secreted progesterone into the medium; progesterone levels appeared to decline with increase in generation number. Cells cultured under serum-free conditions secreted significant amounts of progesterone and insulin-like growth factor II (IGF-II). The progesterone secretion was enhanced by the addition of human follitropin, lutropin, and chorionic gonadotropin but not by growth hormone. These cells, when challenged to varying concentrations of human growth hormone, human chorionic somatomammotropin, human prolactin, chorionic gonadotropin, follitropin, and lutropin, secreted IGF-II into the medium as measured by specific IGF-II RIA. Among these human hormones, chorionic gonadotropin, follitropin, and lutropin were most effective in inducing IGF-II secretion from these cells. When synthetic lutropin-releasing hormone and ..cap alpha..-inhibin-92 were tested, only lutropin-releasing hormone was effective in releasing IGF-II. The results described suggest that cultured human granulosa cells can proliferate and actively secrete progesterone and IGF-II into the medium. IGF-II production in human granulosa cells was influenced by a multi-hormonal complex including human growth hormone, human chorionic somatomammotropin, and prolactin.

    1995-01-01

    Maintenance operations incidents submitted to the Aviation Safety Reporting System (ASRS) between 1986-1992 were systematically analyzed in order to identify issues relevant to human factors and crew coordination. This exploratory analysis involved 95 ASRS reports which represented a wide range of maintenance incidents. The reports were coded and analyzed according to the type of error (e.g, wrong part, procedural error, non-procedural error), contributing factors (e.g., individual, within-team, cross-team, procedure, tools), result of the error (e.g., aircraft damage or not) as well as the operational impact (e.g., aircraft flown to destination, air return, delay at gate). The main findings indicate that procedural errors were most common (48.4%) and that individual and team actions contributed to the errors in more than 50% of the cases. As for operational results, most errors were either corrected after landing at the destination (51.6%) or required the flight crew to stop enroute (29.5%). Interactions among these variables are also discussed. This analysis is a first step toward developing a taxonomy of crew coordination problems in maintenance. By understanding what variables are important and how they are interrelated, we may develop intervention strategies that are better tailored to the human factor issues involved.

    The polymorphism of Alu-repeats, which are located in the introns of the human factor IX gene (copies 1-3), was studied. To identify polymorphic variants, direct sequencing of PCR products that contained appropriate repeats was used. In each case, 20 unrelated X chromosomes were studied. A polymorphic Dra I site was found near the 3{prime}-end of Alu copy 3 within the region of the polyA tract. A PCR-based testing system with internal control of restriction hydrolysis was suggested. Testing 81 unrelated X chromosomes revealed that the frequency of the polymorphic Dra I site is 0.23. Taq I polymorphism, which was revealed in Alu copy 4 of factor IX gene in our previous work, was found to be closely linked to Dra I polymorphism. Studies in linkage between different types of polymorphisms of the factor IX gene revealed the presence of a rare polymorphism in intron a that was located within the same minisatellite region as the known polymorphic insertion 50 bp/Dde I. However, the size of the insertion in our case was 26 bp. Only one polymorphic variant was found among over 150 unrelated X chromosomes derived from humans from Moscow and its vicinity. 10 refs., 4 figs., 1 tab.

Human brucellosis is a severely debilitating disease that requires prolonged treatment with a combination of antibiotics. The disease can result in permanent and disabling sequel, and results in considerable medical expenses in addition to loss of income due to loss of working hours. A study was conducted in Northern Tanzania to determine the risk factors for transmission of brucellosis to humans in Tanzania. METHODS: This was a matched case-control study. Any patient with a positive result by a competitive ELISA (c-ELISA test for brucellosis, and presenting to selected hospitals with at least two clinical features suggestive of brucellosis such as headache, recurrent or continuous fever, sweating, joint pain, joint swelling, general body malaise or backache, was defined as a case. For every case in a district, a corresponding control was traced and matched by sex using multistage cluster sampling. Other criteria for inclusion as a control included a negative c-ELISA test result and that the matched individual would present to hospital if falls sick. RESULTS: Multivariable analysis showed that brucellosis was associated with assisted parturition during abortion in cattle, sheep or goat. It was shown that individuals living in close proximity to other households had a higher risk of brucellosis. People who were of Christian religion were found to have a higher risk of brucellosis compared to other religions. The study concludes that assisting an aborting animal, proximity to neighborhoods, and Christianity were associated with brucellosis infection. There was no association between human brucellosis and Human Immunodeficiency Virus (HIV serostatus. Protecting humans against contact with fluids and tissues during assisted parturition of livestock may be an important means of reducing the risk of transferring brucellosis from

    This Nuclear Regulatory Commission (NRC) sponsored study has identified human-performance issues in new and advanced nuclear power plants. To identify the issues, current industry developments and trends were evaluated in the areas of reactor technology, instrumentation and control technology, human-system integration technology, and human factors engineering (HFE) methods and tools. The issues were organized into seven high-level HFE topic areas: Role of Personnel and Automation, Staffing and Training, Normal Operations Management, Disturbance and Emergency Management, Maintenance and Change Management, Plant Design and Construction, and HFE Methods and Tools. The issues where then prioritized into four categories using a 'Phenomena Identification and Ranking Table' methodology based on evaluations provided by 14 independent subject matter experts. The subject matter experts were knowledgeable in a variety of disciplines. Vendors, utilities, research organizations and regulators all participated. Twenty issues were categorized into the top priority category. This Brookhaven National Laboratory (BNL) technical report provides the detailed methodology, issue analysis, and results. A summary of the results of this study can be found in NUREG/CR-6947. The research performed for this project has identified a large number of human-performance issues for new control stations and new nuclear power plant designs. The information gathered in this project can serve as input to the development of a long-term strategy and plan for addressing human performance in these areas through regulatory research. Addressing human-performance issues will provide the technical basis from which regulatory review guidance can be developed to meet these challenges. The availability of this review guidance will help set clear expectations for how the NRC staff will evaluate new designs, reduce regulatory uncertainty, and provide a well-defined path to new nuclear power plant

    A series of human factors evaluations was undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. The principal sources of radiation are a radioactive isotope, typically cobalt60 (Co-60), or a linear accelerator device capable of producing very high energy x-ray and electron beams. A team of human factors specialists conducted site visits to radiation oncology departments at community hospitals, university centers, and free-standing clinics. In addition, a panel of radiation oncologists, medical physicists, and radiation technologists served as subject matter experts. A function and task analysis was initially performed to guide subsequent evaluations in the areas of user-system interfaces, procedures, training and qualifications, and organizational policies and practices. The present report focuses on an evaluation of the human-system interfaces in relation to the treatment machines and supporting equipment (e.g., simulators, treatment planning computers, control consoles, patient charts) found in the teletherapy environment. The report also evaluates operating, maintenance and emergency procedures and practices involved in teletherapy. The evaluations are based on the function and task analysis and established human engineering guidelines, where applicable.

    As the potential of civil and military helicopters has increased, more complex and demanding missions in increasingly hostile environments have been required. Users, designers, and manufacturers have an urgent need for information about human behavior and function to create systems that take advantage of human capabilities, without overloading them. Because there is a large gap between what is known about human behavior and the information needed to predict pilot workload and performance in the complex missions projected for pilots of advanced helicopters, Army and NASA scientists are actively engaged in Human Factors Research at Ames. The research ranges from laboratory experiments to computational modeling, simulation evaluation, and inflight testing. Information obtained in highly controlled but simpler environments generates predictions which can be tested in more realistic situations. These results are used, in turn, to refine theoretical models, provide the focus for subsequent research, and ensure operational relevance, while maintaining predictive advantages. The advantages and disadvantages of each type of research are described along with examples of experimental results.

    Human factors (HF) study is mandatory to get air transport pilot licences. In aviation, crew resource management (CRM) and declaration of adverse events (feedback) result in improving of air safety. Air missions and surgical procedures have similarities. Bridging the gap is tempting, despite severe warnings against simplistic adaptation. Putting HF theory into surgical practice: how to? Educational principles derived from CRM improve professional attitudes of a team. We propose to translate concepts of CRM to clinical teams. CRM training applying in surgery could allow the work environment to be restructured to reduce human error. Feedback: in aviation, the Bureau of Flight Safety deals with investigations for air events. Pilots, air traffic controllers can anonymously declare nuisance, resulting in a feedback for the whole air force. Adverse events are analysed. Usually, multilevel problems are found, rather than the only responsibility of the last operator. Understanding the mechanisms of human failure finally improves safety. In surgery, CRM and feedback would probably be helpful. Anyway, it requires time; people have to change their mind. Nevertheless people such as fighter pilots, who were very unwilling at the beginning, now consider HF as a cornerstone for security. But it is difficult to estimate the extent of HF-related morbidity and mortality. We propose as a first step to consider CRM and feedback in surgical procedure. HF deals with the mechanisms of human errors and the ways to improve safety and probably improve the surgical team's efficacy.

    Macrophage migration inhibitory factor (MIF) was originally identified as a lymphokine. However, recent work strongly suggests a wider role for MIF beyond the immune system. It is expressed specifically in the differentiating cells of the immunologically privileged eye lens and brain, is a delayed early response gene in fibroblasts, and is expressed in many tissues. Here, the authors report the structure of the remarkably small gene for human MIF that has three exons separated by introns of only 189 and 95 bp and covers less than 1 kb. The cloned sequence also includes 1 kb of 5[prime] flanking region. Primer extension and 5[prime] rapid amplification of cDNA ends (RACE) of human brain RNA both indicate the presence of a single transcription start site in a TATA-less promoter. Northern blot analysis shows a single size of MIF mRNA (about 800 nt) in all human tissues examined. In contrast to previous reports, they find no evidence for multiple genes for MIF in the human genome. 20 refs., 3 figs.

    Cobra venom factor (CVF) is a complement activating protein in cobra venom, which functionally resembles C3b, and has been used for decades for decomplementation of serum to investigate the role of complement in many model systems of disease. The use of CVF for clinical practice is considered impractical because of immunogenicity issues. Humanization of CVF was recently demonstrated to yield a potent CVF-like molecule. In the present study, we demonstrate that mice treated with recombinant humanized CVF (HC3-1496) are protected from myocardial ischemia-reperfusion (MI/R) injuries with resultant preservation of cardiac function. Also, C3 deposition in the myocardium following MI/R was not observed following treatment with HC3-1496. HC3-1496 led to complement activation and depletion of C3, but preserved C5 titers. These data suggest, unlike CVF, HC3-1496 does not form a C5 convertase in the mouse, similar to recent studies in human sera/plasma. These results suggest that humanized CVF (HC3-1496) protects the ischemic myocardium from reperfusion injuries induced by complement activation and represents a novel anti-complement therapy for potential clinical use.

    The 2015 Space Human Factors Engineering (SHFE) Standing Review Panel (from here on referred to as the SRP) met for a site visit in Houston, TX on December 2 - 3, 2015. The SRP reviewed the updated research plans for the Risk of Inadequate Design of Human and Automation/Robotic Integration (HARI Risk), the Risk of Inadequate Human-Computer Interaction (HCI Risk), and the Risk of Inadequate Mission, Process and Task Design (MPTask Risk). The SRP also received a status update on the Risk of Incompatible Vehicle/Habitat Design (Hab Risk) and the Risk of Performance Errors Due to Training Deficiencies (Train Risk). The SRP is pleased with the progress and responsiveness of the SHFE team. The presentations were much improved this year. The SRP is also pleased with the human-centered design approach. Below are some of the more extensive comments from the SRP. We have also made comments in each section concerning gaps/tasks in each. The comments below reflect more significant changes that impact more than just one particular section.

    Full Text Available One of the most important components in today's market is a party decision-making under risk and uncertainty. The first step in making such decisions - to adequately process the information for estimating the future value of assets and the interests of investors probabilities of each particular scenario. The next step is to choose the alternative that has the greatest utility for the investor. Each of these steps is associated with numerous difficulties, the roots of which stem from the specificity of human psychology. The article notes that an integral part of professional risk management is to identify the nature of the object of management in the sphere of economy. Since the domestic theory of risk management is being formed-tion, the problem of a clear comprehensive definition of “risk” becomes now particularly relevant-ness. The article deals with along with economic forecasts of the risks and the human factor in decision-tions solutions. Along with economic forecasts, the report focuses on psychological problems and attempts to take into account the human factor in decision-making at the forecast of risks arising in the company. The important parameters are the status and position of the person in the society, as well as its social well-being. Analysis Meto-ing risk assessment concluded that the need to develop new models and methods of risk management, taking into account the four-lovecheskogo factor. Economic psychology and its applications have developed into a special branch of economic knowledge - the so-called behavioral economics, which surely develops a wide range of economic issues - from the actual theory of individual behavior to the problems of public choice and the financial economy. The most interesting item is the fact that the concept of “risk” is considered from different points of view - as the economist-mathematician with the position, and a psychologist.

    1989-11-01

    An alternative way of teaching informatics, especially health informatics, to health professionals of different categories has been developed and practiced. The essentials of human competence and skill in handling and processing information are presented parallel with the essentials of computer-assisted methodologies and technologies of formal language-based informatics. Requirements on how eventually useful computer-based tools will have to be designed in order to be well adapted to genuine human skill and competence in handling tools in various work contexts are established. On the basis of such a balanced knowledge methods for work analysis are introduced. These include how the existing problems at a workplace can be identified and analyzed in relation to the goals to be achieved. Special emphasis is given to new ways of information analysis, i.e. methods which even allow the comprehension and documentation of those parts of the actually practiced 'human' information handling and processing which are normally overlooked, as e.g. non-verbal communication processes and so-called 'tacit knowledge' based information handling and processing activities. Different ways of problem solving are discussed involving in an integrated human perspective--alternative staffing, enhancement of the competence of the staff, optimal planning of premises as well as organizational and technical means. The main result of this alternative way of education has been a considerably improved user competence which in turn has led to very different designs of computer assistance and man-computer interfaces. It is the purpose of this paper to give a brief outline of the teaching material and a short presentation of the above mentioned results.(ABSTRACT TRUNCATED AT 250 WORDS)

    Little is known about the risk factors of human brucellosis in Jordan. A case-control study was conducted involving 56 Jordanians who had been treated for brucellosis and at least 3 matched controls for each case (n = 247). Matching was for sex, age, locality (the same village) and socioeconomic standard. Univariate and multivariate logistic regression analyses were used. In all, 17 risk factors were examined related to: contact with various livestock, milk and milk product consumption, drinking-water treatment and disease awareness. Most variables were associated with brucellosis in the univariate analysis but the final logistic model included only 4: milking sheep and goats (OR 3.5), consumption of raw feta cheese made from sheep and goat milk (OR 2.8) and consumption of cows' milk (OR 0.4) and boiled feta cheese (OR 0.4). Small ruminant farmers need to be trained in safer milking practices and feta cheese making procedures.

    Being exposed to good teachers has been shown to enhance students' knowledge and their clinical performance, but little is known about the underlying psychological mechanisms that provide the basis for being an excellent medical teacher. Self-Determination Theory (SDT) postulates that more self-regulated types of motivation are associated with higher performance. Social Cognitive Theory (SCT) focuses on self-efficacy that has been shown to be positively associated with performance. To investigate the influences of different types of teaching motivation, teaching self-efficacy, and teachers' perceptions of students' skills, competencies and motivation on teaching quality. Before the winter semester 2014, physicians involved in bedside teaching in internal medicine at the University Medical Center Hamburg-Eppendorf completed a questionnaire with sociodemographic items and instruments measuring different dimensions of teaching motivation as well as teaching self-efficacy. During the semester, physicians rated their perceptions of the participating students who rated the teaching quality after each lesson. We performed a random intercept mixed-effects linear regression with students' ratings of teaching quality as the dependent variable and students' general interest in a subject as covariate. We explored potential associations between teachers' dispositions and their perceptions of students' competencies in a mixed-effects random intercept logistic regression. 94 lessons given by 55 teachers with 500 student ratings were analyzed. Neither teaching motivation nor teaching self-efficacy were directly associated with students' rating of teaching quality. Teachers' perceptions of students' competencies and students' general interest in the lesson's subject were positively associated with students' rating of teaching quality. Physicians' perceptions of their students' competencies were significantly positively predicted by their teaching self-efficacy. Teaching quality

    2013-11-01

    Full Text Available Background: The molecular mechanisms by which myocardial ischemia translates into ventricular remodeling remain unclear. Methods: We investigated whether hypoxia and proinflammatory cytokines are specific inducers of remodeling signals in an in vitro model of cultured adult human ventricular myocytes (AC16 cells. Results:Hypoxia modified the ratio of matrix remodeling factors by increasing the aminoterminal propeptide of type III procollagen (PIIINP and reducing tissue inhibitor of matrix metalloproteinase type 1 (TIMP-1 secretion in AC16 cells. These effects, however, were not associated with either modifications in expression of matrix metalloproteinase type 2, collagen-I or metalloproteinase activity. Hypoxia does, actually increase the production of the cardiac antifibrogenic growth factors, Apelin and VEGF, through an Hypoxia Inducible Factor type 1-dependent mechanism. Concerning proinflammatory signaling pathways, IL1β emerged as a powerful inducer of matrix turnover, since it significantly enhanced PIIINP, TIMP-1 and hyaluronic acid production and increased metalloproteinase activity. In contrast, TNFα did not modify matrix turnover but markedly induced the production of Apelin and VEGF. Conclusion: Hypoxia and increased TNFα activity likely exert cardioprotective actions by activating the cardiac antifibrogenic factors Apelin and VEGF. In contrast, IL1β is a strong promoter of interstitial collagen remodeling that may contribute to ventricular dilation and heart failure in the ischemic myocardium.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Most HPV infections are cleared within two years by the immune system. Only in 5% to 10% of infected women the infection persists determining a high risk of developing cervical intraepithelial neoplasia. The transfer factor (TF) or dialyzable leukocyte extract is an immunomodulator that has been successfully used as an adjuvant in the treatment of intracelular infections such as recurrent herpes virus diseases. One daily dose of transfer factor was given for five days and subsequently each week for five weeks to a group of women with persistent genital papillomavirus infection. We included 13 patients, aged 19 to 45 years, with first intercourse between the ages of 14 to 23, and a mean of three sexual partners in their lifetime. All of them had persistent HPV that had been treated before with local and ablative therapeutic options, including cervical freezing, cervical conization, cauterizing loop, imiquimod and podophyllin. Transfer factor was administered daily for 5 days, and subsequently at 7-day intervals for 5 weeks. We found a clinical significant improvement in the gynaecological evaluation of cervical, vaginal, vulvar and perineal lesions. No recurrences have developed for at least 1 year of follow-up. The use of transfer factor in women with HPV showed resolution of genital lesions, without recurrences for at least one year after the treatment was ended.

    Nav channels are essential for metazoan membrane depolarization, and Nav channel dysfunction is directly linked with epilepsy, ataxia, pain, arrhythmia, myotonia, and irritable bowel syndrome. Human Nav channelopathies are primarily caused by variants that directly affect Nav channel permeability or gating. However, a new class of human Nav channelopathies has emerged based on channel variants that alter regulation by intracellular signaling or cytoskeletal proteins. Fibroblast growth factor homologous factors (FHFs) are a family of intracellular signaling proteins linked with Nav channel regulation in neurons and myocytes. However, to date, there is surprisingly little evidence linking Nav channel gene variants with FHFs and human disease. Here, we provide, to our knowledge, the first evidence that mutations in SCN5A (encodes primary cardiac Nav channel Nav1.5) that alter FHF binding result in human cardiovascular disease. We describe a five*generation kindred with a history of atrial and ventricular arrhythmias, cardiac arrest, and sudden cardiac death. Affected family members harbor a novel SCN5A variant resulting in p.H1849R. p.H1849R is localized in the central binding core on Nav1.5 for FHFs. Consistent with these data, Nav1.5 p.H1849R affected interaction with FHFs. Further, electrophysiological analysis identified Nav1.5 p.H1849R as a gain-of-function for INa by altering steady-state inactivation and slowing the rate of Nav1.5 inactivation. In line with these data and consistent with human cardiac phenotypes, myocytes expressing Nav1.5 p.H1849R displayed prolonged action potential duration and arrhythmogenic afterdepolarizations. Together, these findings identify a previously unexplored mechanism for human Nav channelopathy based on altered Nav1.5 association with FHF proteins. PMID:26392562

    2015-01-01

    In recent years, advances in sensor technology, connectedness and computational power have come together to produce huge data-sets. The treatment and analysis of these data-sets is known as big data analytics (BDA), and the somewhat related term data mining. Fields allied to human factors/ergonomics (HFE), e.g. statistics, have developed computational methods to derive meaningful, actionable conclusions from these data bases. This paper examines BDA, often characterised by volume, velocity and variety, giving examples of successful BDA use. This examination provides context by considering examples of using BDA on human data, using BDA in HFE studies, and studies of how people perform BDA. Significant issues for HFE are the reliance of BDA on correlation rather than hypotheses and theory, the ethics of BDA and the use of HFE in data visualisation.

  9. Connective Tissue Growth Factor Expression in Human Bronchial Epithelial Cells

    2006-01-01

    Connective tissue growth factor (CTGF) is a cysteine-rich protein that promotes extracellular matrix deposition. CTGF is selectively induced by transforming growth factor β and des-Arg kallidin in lung fibroblasts and increases steady-state mRNA levels of α type I collagen, 5α-integrin and fibronectin in fibroblasts. Bronchial epithelial cells have been proposed to functionally interact with lung fibroblasts. We therefore investigated if bronchial epithelial cells are able to synthesize CTGF. Human bronchial epithelial cells were grown to subconfluence in standard growth media. Proliferating cells grown in small airway growth media were harvested following starvation for up to 24 h. Expression of CTGF transcripts was measured by PCR. Immunocytochemistry was also completed using a commercially available antibody.The cells expressed readily detectable CTGF transcripts. Starvation of these cells resulted in a quantitative decline of CTGF transcripts. Direct sequencing of the PCR product identified human CTGF. Immunocytochemistry confirmed intracellular CTGF in the cells and none in negative control cells. We conclude that bronchial epithelial cells could be a novel source of CTGF. Bronchial epithelial cell-derived CTGF could thus directly influence the deposition of collagen in certain fibrotic lung diseases.

    2012-05-01

    Emergency departments are one of the highest risk areas in health care. Emergency physicians have to assemble and manage unrehearsed multidisciplinary teams with little notice and manage critically ill patients. With greater emphasis on management and leadership skills, there is an increasing awareness of the importance of human factors in making changes to improve patient safety. Non-clinical skills are required to achieve this in an information-poor environment and to minimise the risk of errors. Training in these non-clinical skills is a mandatory component in other high-risk industries, such as aviation and, needs to be part of an emergency physician's skill set. Therefore, there remains an educational gap that we need to fill before an emergency physician is equipped to function as a team leader and manager. This review will examine the lessons from aviation and how these are applicable to emergency medicine. Solutions to averting errors are discussed and the need for formal human factors training in emergency medicine.

  11. Mutations and binding sites of human transcription factors

    Kamanu, Frederick Kinyua

    2012-06-01

    Mutations in any genome may lead to phenotype characteristics that determine ability of an individual to cope with adaptation to environmental challenges. In studies of human biology, among the most interesting ones are phenotype characteristics that determine responses to drug treatments, response to infections, or predisposition to specific inherited diseases. Most of the research in this field has been focused on the studies of mutation effects on the final gene products, peptides, and their alterations. Considerably less attention was given to the mutations that may affect regulatory mechanism(s) of gene expression, although these may also affect the phenotype characteristics. In this study we make a pilot analysis of mutations observed in the regulatory regions of 24,667 human RefSeq genes. Our study reveals that out of eight studied mutation types, insertions are the only one that in a statistically significant manner alters predicted transcription factor binding sites (TFBSs). We also find that 25 families of TFBSs have been altered by mutations in a statistically significant manner in the promoter regions we considered. Moreover, we find that the related transcription factors are, for example, prominent in processes related to intracellular signaling; cell fate; morphogenesis of organs and epithelium; development of urogenital system, epithelium, and tube; neuron fate commitment. Our study highlights the significance of studying mutations within the genes regulatory regions and opens way for further detailed investigations on this topic, particularly on the downstream affected pathways. 2012 Kamanu, Medvedeva, Schaefer, Jankovic, Archer and Bajic.

  12. Developing human factors/ergonomics as a design discipline.

    2014-01-01

    This paper deals with internal challenges that the human factors/ergonomics (HFE) research faces when wishing to strengthen its contribution to development of work systems. Three established characteristics of high-quality HFE, i.e., HFE takes a systems approach, HFE is design-driven, and HFE focuses on two closely related outcomes, performance and well-being, are taken as a starting point of a methodological discussion, in which conceptual innovations, e.g. adopting the technology-in-use perspective, are proposed to support development of HFE towards the high-quality aims. The feasibility of the proposed conceptual choices is demonstrated by introducing a naturalistic HFE analysis approach including four HFE functions. The gained experience of the use of this approach in a number of complex work domains allows the conclusion that becoming design-driven appears as that most difficult quality target for HFE to reach. Creating an own design discipline identity in a multi-voiced collaboration is the key internal challenge for human factors/ergonomics.

  14. [Influence of genetic factors on human sexual orientation. Review].

    Science.gov (United States)

    Rodríguez-Larralde, Alvaro; Paradisi, Irene

    2009-09-01

    Human sexual orientation is a complex trait, influenced by several genes, experiential and sociocultural factors. These elements interact and produce a typical pattern of sexual orientation towards the opposite sex. Some exceptions exist, like bisexuality and homosexuality, which seem to be more frequent in males than females. Traditional methods for the genetic study of behavior multifactorial characteristics consist in detecting the presence of familial aggregation. In order to identify the importance of genetic and environmental factors in this aggregation, the concordance of the trait for monozygotic and dizygotic twins and for adopted sibs, reared together and apart, is compared. These types of studies have shown that familial aggregation is stronger for male than for female homosexuality. Based on the threshold method for multifactorial traits, and varying the frequency of homosexuality in the population between 4 and 10%, heritability estimates between 0.27 and 0.76 have been obtained. In 1993, linkage between homosexuality and chromosomal region Xq28 based on molecular approaches was reported. Nevertheless, this was not confirmed in later studies. Recently, a wide search of the genome has given significant or close to significant linkage values with regions 7q36, 8p12 and 10q26, which need to be studied more closely. Deviation in the proportion of X chromosome inactivation in mothers of homosexuals seems to favor the presence of genes related with sexual orientation in this chromosome. There is still much to be known about the genetics of human homosexuality.

    Systems, facilities and equipment are periodically updated during a power plant's lifetime. This has human factors implications, especially if the central control room is involved. Human factors work may therefore be required. There is an extensive literature on human factors itself, but not so much on how it is verified and validated. Therefore, HRP and the Swedish Nuclear Power Inspectorate commissioned a study. The objective was to review the literature and establish a knowledge base on verification and validation (V and V) of human factors issues. The report first discusses verification and validation as applied to human factors work. It describes a design process and the typical human factors topics involved. It then presents a generic method for V and V of human factors. This is built on a review of standards, guidelines and other references given in an annotated bibliography. The method is illustrated by application to some human factors topics.

    This project has been performed as cooperative research between KAERI and USNRC. Human factors issues related to soft controls, which is one of key features of advanced HSI, are identified in this project. The issues are analyzed for the evaluation approaches in either experimental or analytical ways. Also, issues requiring additional researches for the evaluation of advanced HSI are identified in the areas of advanced information systems design, computer-based procedure systems, soft controls, human systems interface and plant modernization process, and maintainability of digital systems. The issues are analyzed to discriminate the urgency of researches on it to high, medium, and low levels in consideration of advanced HSI development status in Korea, and some of the issues that can be handled by experimental researches are identified. Additionally, an experimental study is performed to compare operator's performance on human error detection in advanced control rooms vs. in conventional control rooms. It is found that advanced control rooms have several design characteristics hindering operator's error detection performance compared to conventional control rooms.

    1984-02-01

    The expression of receptors for epidermal growth factor (EGF-R) was determined in 29 samples of brain tumors from 22 patients. Primary gliogenous tumors, of various degrees of cancer, five meningiomas, and two neuroblastomas were examined. Tissue samples were frozen in liquid nitrogen immediately after the operation and stored at -70 degrees until use. Cerebral tissue samples from 11 patients who died from diseases not related to the central nervous system served as controls. Immunoprecipitation of functional EGF-R-kinase complexes revealed high levels of EGF-R in all of the brain tumors of nonneuronal origin that were examined. The level of EGF-R varied between tumors from different patients and also between specimens prelevated from different areas of the same tumor. In contrast, the levels of EGF-R from control specimens were invariably low. The biochemical properties of EGF-R in brain tumor specimens were found to be indistinguishable from those of the well-characterized EGF-R from the A-431 cell line, derived from human epidermoid carcinomas. Human brain EGF-R displays a molecular weight of 170,000 by polyacrylamide-sodium dodecyl sulfate gel electrophoresis. It is phosphorylated mainly in tyrosine residues and shows a 2-dimensional phosphopeptide map similar to that obtained with the phosphorylated EGF-R from membranes of A-431 cells. Our observations suggest that induction of EGF-R expression may accompany the malignant transformation of human brain cells of nonneuronal origin.

    2016-01-01

    Inflammation and dysfunction of endothelial cells are thought to be triggers for the secretion of Von Willebrand factor. The aim of this study was to examine the effects of the inflammatory cytokines interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor-alpha (TNF-α) and the coagulation factors, tissue factor and thrombin on the release and cleavage potential of ultra-large von Willebrand factor (ULVWF) and its cleavage protease by cultured human umbilical vein endothelial cells (HUVEC). HUVEC were treated with IL-6, IL-8, and TNF-α, tissue factor (TF) and thrombin, and combinations thereof for 24 hours under static conditions. The cells were then exposed to shear stress after which the VWF-propeptide levels and the VWF cleavage protease, ADAMTS13 content were measured. All treatments and their combinations, excluding IL-6, significantly stimulated the secretion of VWF from HUVEC. The VWF secretion from the HUVEC was stimulated most by the combination of TF with TNF-α. Slightly lower levels of ADAMTS13 secretion were found with all treatments. This may explain the thrombogenicity of patients with inflammation where extremely high VWF levels and slightly lower ADAMTS13 levels are present.

  1. Helicopter flights with night-vision goggles: Human factors aspects

    Science.gov (United States)

    Brickner, Michael S.

    1989-01-01

    Night-vision goggles (NVGs) and, in particular, the advanced, helmet-mounted Aviators Night-Vision-Imaging System (ANVIS) allows helicopter pilots to perform low-level flight at night. It consists of light intensifier tubes which amplify low-intensity ambient illumination (star and moon light) and an optical system which together produce a bright image of the scene. However, these NVGs do not turn night into day, and, while they may often provide significant advantages over unaided night flight, they may also result in visual fatigue, high workload, and safety hazards. These problems reflect both system limitations and human-factors issues. A brief description of the technical characteristics of NVGs and of human night-vision capabilities is followed by a description and analysis of specific perceptual problems which occur with the use of NVGs in flight. Some of the issues addressed include: limitations imposed by a restricted field of view; problems related to binocular rivalry; the consequences of inappropriate focusing of the eye; the effects of ambient illumination levels and of various types of terrain on image quality; difficulties in distance and slope estimation; effects of dazzling; and visual fatigue and superimposed symbology. These issues are described and analyzed in terms of their possible consequences on helicopter pilot performance. The additional influence of individual differences among pilots is emphasized. Thermal imaging systems (forward looking infrared (FLIR)) are described briefly and compared to light intensifier systems (NVGs). Many of the phenomena which are described are not readily understood. More research is required to better understand the human-factors problems created by the use of NVGs and other night-vision aids, to enhance system design, and to improve training methods and simulation techniques.

    Village, Judy; Searcy, Cory; Salustri, Filipo; Patrick Neumann, W

    2015-01-01

    The 'design for human factors' grounded theory explains 'how' human factors (HF) went from a reactive, after-injury programme in safety, to being proactively integrated into each step of the production design process. In this longitudinal case study collaboration with engineers and HF Specialists in a large electronics manufacturer, qualitative data (e.g. meetings, interviews, observations and reflections) were analysed using a grounded theory methodology. The central tenet in the theory is that when HF Specialists acclimated to the engineering process, language and tools, and strategically aligned HF to the design and business goals of the organisation, HF became a means to improve business performance. This led to engineers 'pulling' HF Specialists onto their team. HF targets were adopted into engineering tools to communicate HF concerns quantitatively, drive continuous improvement, visibly demonstrate change and lead to benchmarking. Senior management held engineers accountable for HF as a key performance indicator, thus integrating HF into the production design process. Practitioner Summary: Research and practice lack explanations about how HF can be integrated early in design of production systems. This three-year case study and the theory derived demonstrate how ergonomists changed their focus to align with design and business goals to integrate HF into the design process.

    For decades, Space Life Sciences and NASA as an Agency have considered NASA-STD-3000, Man-Systems Integration Standards, a significant contribution to human spaceflight programs and to human-systems integration in general. The document has been referenced in numerous design standards both within NASA and by organizations throughout the world. With research program and project results being realized, advances in technology and new information in a variety of topic areas now available, the time arrived to update this extensive suite of requirements and design information. During the past several years, a multi-NASA center effort has been underway to write the update to NASA-STD-3000 with standards and design guidance that would be applicable to all future human spaceflight programs. NASA-STD-3001 - Volumes 1 and 2 - and the Human Integration Design Handbook (HIDH) were created. Volume 1, Crew Health, establishes NASA s spaceflight crew health standards for the pre-flight, in-flight, and post-flight phases of human spaceflight. Volume 2, Human Factors, Habitability and Environmental Health, focuses on the requirements of human-system integration and how the human crew interacts with other systems, and how the human and the system function together to accomplish the tasks for mission success. The HIDH is a compendium of human spaceflight history and knowledge, and provides useful background information and research findings. And as the HIDH is a stand-alone companion to the Standards, the maintenance of the document has been streamlined. This unique and flexible approach ensures that the content is current and addresses the fundamental advances of human performance and human capabilities and constraints research. Current work focuses on the development of new sections of Volume 2 and collecting updates to the HIDH. The new sections in development expand the scope of the standard and address mission operations and support operations. This effort is again collaboration

    Objectives To explore the change of endogenic nerve growth factor (NGF) expression in human glioma cells infected with human cytomegalovirus (HCMV). Methods U251 cells were cultured in RPMI 1640 culture medium and infected with HCMV AD169 strain in vitro to establish a cell model of viral infection. Morphologic changes of U251 cells were observed under inverted microscope before and after infection with HCMV. Expression of NGF gene and protein of cells was detected by RT-PCR and Western blotting before and after infection with HCMV. Results The cytopathic effects of HCMV-infected cells appeared on day 5 after infection. However, differential NGF expression was evident on day 7. NGF expression was decreased significantly in U251 cells on day 7 after infection in comparison with control group (P<0.05). Conclusion HCMV can down-regulate endogenous NGF levels in human glioma cell line U251.

    This paper summarizes my experiences teaching a 28-hour course on the bacterial world for undergraduate students in the humanities and the social sciences at the Hebrew University of Jerusalem. This course was offered in the framework of a program in which students must obtain credit points for courses offered by other faculties to broaden their education. Most students had little biology in high school and had never been exposed to the basics of chemistry. Using a historical approach, highlighting the work of pioneers such as van Leeuwenhoek, Koch, Fleming, Pasteur, Winogradsky and Woese, I covered a broad area of general, medical, environmental and evolutionary microbiology. The lectures included basic concepts of organic and inorganic chemistry necessary to understand the principles of fermentations and chemoautotrophy, and basic molecular biology to explain biotechnology using transgenic microorganisms and molecular phylogeny. Teaching the basics of microbiology to intelligent students lacking any background in the natural sciences was a rewarding experience. Some students complained that, in spite of my efforts, basic concepts of chemistry remained beyond their understanding. But overall the students' evaluation showed that the course had achieved its goal.

  11. Self-perceived Occupational Prestige among Romanian Teaching Staff: Organisational Explicative Factors

    2015-12-01

    Full Text Available Most studies discuss occupational prestige by stressing out the macro-social aspects related to specific social stratification models. This paper aims to address the impact of organizational aspects on how teachers perceive the prestige of their occupational group, moving the focus on the micro-social context of their daily activity. The way teaching staff evaluate the social prestige of their profession fulfils normative and motivational functions and is, hence, reflected in how they actually perform their professional roles, serving both explicative and prospective purposes. In trying to identify the main factors that can explain the self-perceived level of occupational prestige among educators and teachers, we conducted a national level study among Romanian teachers (N=2165 from preschool to high school educational stages. Within the explicative model (R²=0.38, we were able to group the factors in three main categories: material conditions, bureaucratic and relational aspects. The findings reveal that teachers’ involvement in bureaucratic activities such as elaborating different reports, as well as a lower level of satisfaction regarding the relation they have with students, parents and representatives of the school's management end up decreasing the self-perceived occupational prestige. Our study lays emphasis on the fact that organizational factors influence teachers' selfperceived prestige and, thus, can affect the overall quality of the educational act. Therefore, to improve this, a greater involvement of national and local authorities in providing better material conditions in schools, in supporting the debureaucratization of the educational system and re-evaluating the role of teacher-student-parent communication triad is needed.

  12. The quarantine of philosophy in medical education: why teaching the humanities may not produce humane physicians.

    Science.gov (United States)

    Stempsey, W E

    1999-01-01

    Patients increasingly see physicians not as humane caregivers but as unfeeling technicians. The study of philosophy in medical school has been proposed to foster critical thinking about one's assumptions, perspectives and biases, encourage greater tolerance toward the ideas of others, and cultivate empathy. I suggest that the study of ethics and philosophy by medical students has failed to produce the humane physicians we seek because of the way the subject matter is quarantined in American medical education. First, the liberal arts are seen as the province of undergraduate education, and not medical school. Second, philosophy, when taught in medical school, is seen by students as just one subject to be mastered along with many other more important ones, and not as a way to foster critical thinking and empathy. What is needed is a new pedagogy that combines both cognitive and affective elements to implant and nourish the liberal arts in students. Removing the quarantine of philosophy from other facets of medical education is an important first step.

    Surface texture sensation is significant for business success, in particular for solid surfaces for most of the materials; including foods. Mechanisms of roughness perception are still unknown, especially under different conditions such as lubricants with varying viscosities, different temperatures, or under different force loads during the observation of the surface. This work aims to determine the effect of those unknown factors, with applied sensory tests on 62 healthy participants. Roughness sensation of fingertip was tested under different lubricants including water and diluted syrup solutions at room temperature (25C) and body temperature (37C) by using simple pair-wise comparison to observe the just noticeable difference threshold and perception levels. Additionally, in this research applied force load during roughness observation was tested with pair-wise ranking method to illustrate its possible effect on human sensation. Obtained results showed that human's capability of roughness discrimination reduces with increased viscosity of the lubricant, where the influence of the temperature was not found to be significant. Moreover, the increase in the applied force load showed an increase in the sensitivity of roughness discrimination. Observed effects of the applied factors were also used for estimating the oral sensation of texture during eating. These findings are significant for our fundamental understanding to texture perception, and for the development of new food products with controlled textural features. Texture discrimination ability, more specifically roughness discrimination capability, is a significant factor for preference and appreciation for a wide range of materials, including food, furniture, or fabric. To explore the mechanism of sensation capability through tactile senses, it is necessary to identify the relevant factors and define characteristics that dominate the process involved. The results that will be obtained under these principles

    The U.S. Department of Energy (DOE) has funded major environmental technology developments over the past several years. One area that received significant attention is robotics, which has resulted in the development of a wide range of unique robotic systems tailored to the many tasks unique to the DOE complex. These systems are often used in highly hazardous environments, which reduces or eliminates worker exposures. The DOE, concurrent with the technology development initiative, also established and funded a 5-yr cooperative agreement intended to interface with the technology development community-with specific attention to the occupational safety and health aspects associated with individual technologies through human factors and hazard assessments. This program is now in its third year.

    This paper presents the direction being taken in the Canadian regulatory program to guide the incorporation of human factors principles, knowledge, information, and methods in activities such as those that address the design and implementation of the advanced control room (ACR) in nuclear power plants. Within the current activity in the international nuclear industry aimed at the development of ACR concepts, the steps that are being taken to develop design review guidelines for ACRs, such as the work sponsored by the U.S. Nuclear Regulatory Commission are filling an identified important need. The salient feature of most ACR projects is the increased use of digital technology for the analysis, synthesis, management, and display of information. The greatly increased functionality of the devices that can be introduced during such projects allows changes to be made at the design and implementation stages that are not necessarily based on prior function allocation or task analyses.

    Full Text Available Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behavior, compartmentalization, and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. Problems still occurred despite of the adequate fire safety systems installed. For most people in high-risk buildings, not all accidents were caused by them. They were more likely to be the victims of a fire that occurred. Besides damaging their properties and belongings, some people were burned to death for not knowing what to do if fire happens in their place. This paper will present the human factors in fire safety management and prevention system.

    The third plague epidemic in Harbin broke out in 1946 and ended in 1954. Different from the first two plague epidemics (imported), the third prevalence was both imported and idiopathic infectious disease which was caused by human factors. Japanese troops set forbidden zones to build a biological weapon center, which destroyed the natural environment and offered a good growth condition for Citellus Undulatus. In 1945, on the eve of surrender, the Japanese blew up the Unit 731 germ factory located in a bungalow district, which caused diffusion of infected plague fleas. Mice of the district were infected and a man-made plague focus was created. During the prevalence of the third plague, prevention departments at all levels took a series of actions and with people's efforts, the plague was effectively controlled.

    To assess the effectiveness of human patient simulation to teach patient safety, team-building skills, and the value of interprofessional collaboration to pharmacy students. Five scenarios simulating semi-urgent situations that required interprofessional collaboration were developed. Groups of 10 to 12 health professions students that included 1 to 2 pharmacy students evaluated patients while addressing patient safety hazards. Pharmacy students' scores on 8 of 30 items on a post-simulation survey of knowledge, skills, and attitudes improved over pre-simulation scores. Students' scores on 3 of 10 items on a team building and interprofessional communications survey also improved after participating in the simulation exercise. Over 90% of students reported that simulation increased their understanding of professional roles and the importance of interprofessional communication. Simulation training provided an opportunity to improve pharmacy students' ability to recognize and react to patient safety concerns and enhanced their interprofessional collaboration and communication skills.

    Recent studies indicate that various types of vesicles, like microparticles (MP) and exosomes, are present in blood, saliva, bone marrow, urine and synovial fluid. These vesicles, which are released upon activation or shear stress, are thought to play a role in coagulation, neovascularisation, inflammation and intercellular signalling. Seminal fluid is a cell-, sperm- and protein-rich suspension. Although seminal fluid is known to contain vesicles like prostasomes, MP and exosomes have never been characterised. Therefore, the aim of our study was to analyse and characterise vesicles in seminal fluid in male partners of patients undergoing controlled ovarian stimulation for IVF/ICSI. MP from seminal fluid of patients during routine IVF/ICSI procedures were detected and analysed with flow cytometry (FACS) and transmission electron microscopy (TEM), using antibodies against tissue factor (TF), CD10, CD13, CD26 and annexin V. The coagulant properties of vesicles were studied using a fibrin generation test. MP were detected in human seminal fluid by both flow cytometry and TEM. Seminal fluid-derived MP expressed CD10, CD13, CD26 and TF, which was highly procoagulant and a powerful trigger of the extrinsic pathway of coagulation. The extent to which the procoagulant activity of MP in seminal fluid contributes to the implantation process itself and therefore affects human reproduction needs to be further elucidated.

    Stem cells are capable of generating various cell lines and can be obtained from adult or embryonic tissues for clinical therapies. Stem cells from deciduous dental pulp are among those that are easily obtainable from adult tissues and have been widely studied because of their ability to differentiate into a variety of cell lines in the presence of various chemical mediators. We have analyze the expression of several proteins related to the differentiation and proliferative potential of cell populations that compose the tooth germ of human fetuses. We evaluate 20 human fetuses of both genders. After being paraffin-embedded, cap and bell stages of tooth germ development were subjected to immunohistochemistry for the following markers: Oct-4, Nanog, Stat-3 and Sox-2. The studied antibodies showed nuclear or cytoplasmic immunnostaining within various anatomical structures and with various degrees of expression, indicating the action of these proteins during tooth development. We conclude that the interrelationship between these transcription factors is complex and associated with self-renewal and cell differentiation. Our results suggest that the expression of Oct-4, Nanog, Sox-2 and Stat-3 are related to differentiation in ameloblasts and odontoblasts.

    Stress responses within dyads are modulated by interactions such as mutual emotional support and conflict. We investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a laboratory setting. Salivary cortisol was measured and questionnaires were used to assess owner and dog personality as well as owners' social attitudes towards the dog and towards other humans. We calculated the individual coefficient of variance of cortisol (iCV = sd/mean*100) over the different test situations as a parameter representing individual variability of cortisol concentration. We hypothesized that high cortisol variability indicates efficient and adaptive coping and a balanced individual and dyadic social performance. Female owners of male dogs had lower iCV than all other owner gender-dog sex combinations (F = 14.194, pNeuroticism (NEO-FFI) and of owners who were insecure-ambivalently attached to their dogs (FERT), had low iCV (F = 4.290, p = 0.041 and F = 5.948, p = 0.016), as had dogs of owners with human-directed separation anxiety (RSQ) or dogs of owners with a strong desire of independence (RSQ) (F = 7.661, p = 0.007 and F = 9.192, p = 0.003). We suggest that both owner and dog social characteristics influence dyadic cortisol variability, with the human partner being more influential than the dog. Our results support systemic approaches (i.e. considering the social context) in science and in counselling. PMID:28178272

    Compelling evidences suggest that fibroblast growth factor-2 (FGF-2) plays important roles in tumor growth, angiogenesis and metastasis. Molecules blocking the FGF-2 signaling have been proposed as anticancer agents. Through screening of a human scFv phage display library, we have isolated several human single-chain Fv fragments (scFvs) that bind to human FGF-2. After expression and purification in bacteria, one scFv, named 1A2, binds to FGF-2 with a high affinity and specificity, and completes with FGF-2 binding to its receptor. This 1A2 scFv was then cloned into the pIgG1 vector and expressed in 293T cells. The purified hIgG1-1A2 antibody showed a high binding affinity of 8 x 10{sup -9} M to rhFGF-2. In a set of vitro assays, it inhibited various biological activities of FGF-2 such as the proliferation, migration and tube formation of human umbilical vein endothelial cells. More importantly, hIgG1-1A2 antibody also efficiently blocked the growth while inducing apoptosis of glioma cells. For the first time, we generated a human anti-FGF-2 antibody with proven in vitro anti-tumor activity. It may therefore present a new therapeutic candidate for the treatment of cancers that are dependent on FGF-2 signaling for growth and survival.

    The anti-human epidermal growth factor receptor (EGF-R) humanized antibody h-R3 (IgG{sub 1}), which binds to an extracellular domain of EGF-R, was used to evaluate the biodistribution on nude mice xenografted with A431 epidermoid carcinoma cell line. Results are compared with its murine version ior egf/r3 monoclonal antibody (mAb). Twenty-one athymic female 4NMRI nu/nu mice were injected intravenously with 10 {mu}g/100 {mu}Ci of {sup 99m}Tc-labeled mAbs. The mAb ior C5 that recognizes an antigen expressed preferentially on the surface of malignant and cytoplasm of normal colorectal cells was used as negative control. Immunoreactivity of {sup 99m}Tc-labeled mAbs was measured by enzyme linked immunosorbent assay on A431 cell line and the immunoreactive fractions determined by Lindmo method. Among all organs significant accumulation was found in tumor (6.14{+-}2.50 %ID/g, 5.06{+-}2.61 %ID/g for murine and humanized mAbs, respectively) 4 h after injection. The immunoreactive fractions were found to be 0.88 and 0.81 for murine and humanized mAb, respectively. Thus, we expect better results using the humanized mAb h-R3 for diagnostic immunoscintigraphy.

    The expression of basic fibroblast growth factor (bFGF) and fibroblast growth factor receptor-1 (FGFR-1) in human meningiomas and the relationships between their expression and the tumors' histological features and angiogenesis were investigated by means of immunohistochemical technique. The expression of bFGF and FGFR-1 was detected by antibody of bFGF or FGFR-1.The tumors' angiogenesis was evaluated by microvascular density (MVD) and, which was observed by use of CD34-antibody immunohistochemically. The results showed that there were varied degrees of the expression of bFGF and FGFR-1 proteins in meningiomas. The expression was correlated with the tumors' histological characters and angiogenesis. It was concluded that bFGF and FGFR-1 might play important roles in meningiomas' angiogenesis and proliferation. The expression positive rate of bFGF and FGFR-1 may provide an indication of evaluating the histological and malignant degree of the tumor.

    Limited human resources are a major impediment to achieving the UN health-related Millennium Development Goals in a number of Pacific Island Countries (PICs). Lack of education capacity to support competency development in medicine supply management is one of the main issues affecting workforce development in this region, which is characterised by disparate service delivery due to the range of environments in which supply occurs (ie urban, rural and remote), geographical challenges and cultural practices associated with teaching and learning. The supply of medicines, and an adequate pharmacy workforce with appropriate competencies is crucial to ensuring a well-functioning pharmaceutical system. In this region approximately 80% of patients access healthcare in rural areas without a pharmacist, thus local health personnel must be competent in pharmaceutical management relevant to the local context and culture. A new approach involves a partnership between the UN Population Fund Suva Sub-Regional Office, University of Canberra, Ministry of Health officials and the heath personnel within identified PICs, starting with the need to understand local culture and its impact on learning and teaching, and the mapping of competency requirements and an understanding of currently available information and materials. This information will be used to develop and trial new pedagogical approaches to training health personnel involved in essential medicines supply management, to improve medicines availability for patients in their own environment. The focus of this review was to determine what cultural and learning factors need to be considered when developing a curriculum for South Pacific pharmaceutical health personnel who work across a range of practice environments. A 'realist methodology' consisting of a systematic investigation of the published literature and a targeted review of the 'grey' literature was used. All relevant literature was retrieved and coded manually using

    The primary objective of the United States (U.S.) Department of Energy (DOE) Light Water Reactor Sustainability (LWRS) program is to sustain operation of the existing commercial nuclear power plants (NPPs) through a multi-pathway approach in conducting research and development (R&D). The Advanced Instrumentation, Information, and Control (II&C) System Technologies pathway conducts targeted R&D to address aging and reliability concerns with legacy instrumentation and control (I&C) and other information systems in existing U.S. NPPs. Control room modernization is an important part following this pathway, and human factors experts at Idaho National Laboratory (INL) have been involved in conducting R&D to support migration of new digital main control room (MCR) technologies from legacy analog and legacy digital I&C. This paper describes a human factors engineering (HFE) process that supports human-system interface (HSI) design in MCR modernization activities, particularly with migration of old digital to new digital I&C. The process described in this work is an expansion from the LWRS Report INL/EXT-16-38576, and is a requirements-driven approach that aligns with NUREG-0711 requirements. The work described builds upon the existing literature by adding more detail around key tasks and decisions to make when transitioning from HSI Design into Verification and Validation (V&V). The overall objective of this process is to inform HSI design and elicit specific, measurable, and achievable human factors criteria for new digital technologies. Upon following this process, utilities should have greater confidence with transitioning from HSI design into V&V.

    Objective:To construct a Pichia pastoris (P. Pastoris) expression vector of human intestinal trefoil factor (hITF) and study its expression and purification procedures. Methods:hITF gene encoding mature peptide was modified with a polyhistidine tag sequence at the N-terminal, and then inserted into the P. Pastoris expression vector pGAPZαA at the ownstream of the α-mating factor signal. After gene sequencing, the recombinant pGAPZαA-hITF was transformed into the P. Pastoris strain X-33 with lithium chloride. rhITF was induced to constitutively express in shake flask, and then analyzed with Tricine SDS-PAGE and Western blotting. The obtained rhITF was isolated from the cultured supernatants y ammonium sulfate precipitation, Ni-NTA affinity chromatography, and ultrafiltration. Results:The correctness and integrity of rhITF were identified by restriction digestion and gene sequencing. rhITF was successfully expressed to 50 mg/L as a secretive protein. After purification, the purity was above 95%.Tricine SDS-PAGE and Western-blot analysis howed that rhITF presented as a single band with a molecular weight of 10 kDa, a little larger than 7 879 Da as assayed by mass spectrometry analysis. Conclusion:hITF P. Pastoris expression vector is successfully constructed and rhITF is expressed in P. Pastoris at commercially relevant level. This research lays foundation for the further functional tudying of hITF.

    Coconut oil is being heavily promoted as a healthy oil, with benefits that include support of heart health. To assess the merits of this claim, the literature on the effect of coconut consumption on cardiovascular risk factors and outcomes in humans was reviewed. Twenty-one research papers were identified for inclusion in the review: 8 clinical trials and 13 observational studies. The majority examined the effect of coconut oil or coconut products on serum lipid profiles. Coconut oil generally raised total and low-density lipoprotein cholesterol to a greater extent than cis unsaturated plant oils, but to a lesser extent than butter. The effect of coconut consumption on the ratio of total cholesterol to high-density lipoprotein cholesterol was often not examined. Observational evidence suggests that consumption of coconut flesh or squeezed coconut in the context of traditional dietary patterns does not lead to adverse cardiovascular outcomes. However, due to large differences in dietary and lifestyle patterns, these findings cannot be applied to a typical Western diet. Overall, the weight of the evidence from intervention studies to date suggests that replacing coconut oil with cis unsaturated fats would alter blood lipid profiles in a manner consistent with a reduction in risk factors for cardiovascular disease.

    Full Text Available Introduction. The objective of this research was to learn what variables determine satisfaction with the teaching-learning process (TLP, from the perspective of students participating in the ECTS experience (European Credit Transfer System. Method. A total of 1490 students from the Universities of Almería and Granada (Spain participated in an evaluation of their class subjects. They completed a protocol for evaluating the ECTS experience. Analyses of Variance were carried out, taking different measures as independent variables, such as student’s grade average, year in school, branch of studies, workload in terms of ECTS credits per subject and the use of e-learning. Perception of TLP was used as the dependent variable.Results. Variables that establish significant differences in the perception of the TL process were determined. Student’s grade average (in favor of high performers, year in school (in favor of earlier years, ECTS load (in favor of subjects with a medium load of credits, and e-learning (in favor of its use establish a sufficiently delimited profile of factors that trigger a favorable perception of this process. Discussion and Conclusions. The appearance of significant differences showed that perception of TLP depends on different variables that were assessed. Thus, it is important to take these variables into consideration in giving shape to the European Higher Education Area. We comment on the results and their implications for the large-scale implementation of the ECTS.

    Since the 1980s wildlife managers in the United States and Canada have expressed increasing concern about the physical threat posed by cougars (Puma concolor) to humans. We developed a conceptual framework and analyzed 386 human–cougar encounters (29 fatal attacks, 171 instances of nonfatal contact, and 186 close-threatening encounters) to provide information relevant to public safety. We conceived of human injury and death as the outcome of 4 transitions affected by different suites of factors: (1) a human encountering a cougar: (2) given an encounter, odds that the cougar would be aggressive; (3) given aggression, odds that the cougar would attack; and (4) given an attack, odds that the human would die. We developed multivariable logistic regression models to explain variation in odds at transitions three and four using variables pertaining to characteristics of involved people and cougars. Young (≤ 2.5 years) or unhealthy (by weight, condition, or disease) cougars were more likely than any others to be involved in close (typically females were more likely than males to attack, and of attacking animals, adults were more likely than juveniles to kill the victim (32% versus 9% fatality, respectively). During close encounters, victims who used a weapon killed the involved cougar in 82% of cases. Other mitigating behaviors (e.g., yelling, backing away, throwing objects, increasing stature) also substantially lessened odds of attack. People who were moving quickly or erratically when an encounter happened (running, playing, skiing, snowshoeing, biking, ATV-riding) were more likely to be attacked and killed compared to people who were less active (25% versus 8% fatality). Children (≤ 10 years) were more likely than single adults to be attacked, but intervention by people of any age reduced odds of a child’s death by 4.6×. Overall, cougar attacks on people in Canada and the United States were rare (currently 4 to 6/year) compared to attacks by large felids and

    Background: The surgical extraction of impacted third molars is a common oral surgical procedure, and it is often associated with complications such as sensory nerve damage, dry socket, pain, swelling, trismus, infection and hemorrhage. Aim: The aim of this study was to determine the surgical indications and risk factors for complications of third molar surgery at a Nigerian teaching hospital. Materials and Methods: Medical records of patients referred to the Oral Surgery Clinic of our institution for surgical extraction of their impacted mandibular third molars from January 2008 to December 2010 were retrospectively examined. Information on patients’ demography, types of impaction, operative parameters and complications were obtained and analyzed using Statistical Package for Social Sciences (SPSS Version 13), Chicago, IL, USA. A P pericoronitis (154/330 [46.7%]) was the most common indication for extraction. The complications were delayed healing (19/330 [5.8%]), alveolar, osteitis (9/330 [2.7%]) and injury to alveolar nerve (2/330 [0.6%]). Cigarette smoking (P < 0.001), Oral contraceptives use (P = 0.01), age of the patient (P = 0.03) and the surgeon's experience (P = 0.04) were found to be significantly associated with the development of alveolar osteitis; nerves injuries were significantly associated with the raising of a lingual flap (P < 0.001) and the technique of surgery (P ≤ 0.001). Conclusion: The age of the patient, cigarette smoking and oral contraceptive use at the time of surgery are some of the factors affecting outcome in third molar surgery. PMID:25506490

  20. Plastination and its importance in teaching anatomy. Critical points for long-term preservation of human tissue.

    2014-03-01

    Most medical curricula rely on human bodies for teaching macroscopic anatomy. Over the past 20 years, plastination has become an important means of preservation of organs, for well dissected specimens or for body slices. Here, several critical points regarding body donation with legal and ethical considerations for long-term preservation, the use of cadavers in teaching and the preparation of plastinates as an additional teaching tool will be discussed. Silicone S10 is the gold standard in the preparation of plastinates. An important point to respect is the preparation of specimens, since only very well dissected body parts or excellent tissue sections should be plastinated to show the extraordinary aspects of the human anatomy. The preparation of thin and transparent sections and preservation with P40 polyester provides an additional technique to prepare resistant body slices. A selection of samples prepared by S10 and P40 are shown and compared. In addition, Prussian or Berlin blue staining of brain slices is shown to discriminate better between gray and white matter and demonstrate neuroanatomical structures. These plastinates have been used for many years in teaching first- and second-year medical students and have not lost their appeal. Students and staff appreciate the use of such plastinates. One of the advantages is that their use is not restricted to the dissection hall; slices and body parts can be used in any lecture room or in small group teaching. Therefore, ethical and legal questions need to be addressed regarding their specific use. Plastinates do not replace the traditional dissection courses, since students learn best the anatomical features of a given region by hands-on dissection and by exploratory anatomy. Furthermore, plastinates are more rigid and do not allow demonstration of hidden structures; they also become more cumbersome for endoscopy or are too rigid for demonstrating mechanical features of joints. However, although not a replacement

    The aim of this paper is to describe a human factors assessment guide for the study of the erroneous characteristic of operators in nuclear power plants (NPPs). We think there are still remaining the human factors issues such as an uneasy emotion, fatigue and stress, varying mental workload situation by digital environment, and various new type of unsafe response to digital interface for better decisions, although introducing an advanced main control room. These human factors issues may not be resolved through the current human reliability assessment which evaluates the total probability of a human error occurring throughout the completion of a specific task. This paper provides an assessment guide for the human factors issues a set of experimental methodology, and presents an assessment case of measurement and analysis especially from neuro physiology approach. It would be the most objective psycho-physiological research technique on human performance for a qualitative analysis considering the safety aspects. This paper can be trial to experimental assessment of erroneous behaviors and their influencing factors, and it can be used as an index for recognition and a method to apply human factors engineering V and V, which is required as a mandatory element of human factor engineering program plan for a NPP design.

    Full Text Available Trypanosome lytic factor (TLF is a high-density lipoprotein (HDL subclass providing innate protection to humans against infection by the protozoan parasite Trypanosoma brucei brucei. Two primate-specific plasma proteins, haptoglobin-related protein (Hpr and apolipoprotein L-1 (ApoL-1, have been proposed to kill T. b. brucei both singularly or when co-assembled into the same HDL. To better understand the mechanism of T. b. brucei killing by TLF, the protein composition of TLF was investigated using a gentle immunoaffinity purification technique that avoids the loss of weakly associated proteins. HDL particles recovered by immunoaffinity absorption, with either anti-Hpr or anti-ApoL-1, were identical in protein composition and specific activity for T. b. brucei killing. Here, we show that TLF-bound Hpr strongly binds Hb and that addition of Hb stimulates TLF killing of T. b. brucei by increasing the affinity of TLF for its receptor, and by inducing Fenton chemistry within the trypanosome lysosome. These findings suggest that TLF in uninfected humans may be inactive against T. b. brucei prior to initiation of infection. We propose that infection of humans by T. b. brucei causes hemolysis that triggers the activation of TLF by the formation of Hpr-Hb complexes, leading to enhanced binding, trypanolytic activity, and clearance of parasites.

    Progress toward improving patient safety has been slow despite engagement of the health care community in improvement efforts. A potential reason for this sluggish pace is the inadequate integration of human factors and ergonomics principles and methods in these efforts. Patient safety problems are complex and rarely caused by one factor or component of a work system. Thus, health care would benefit from human factors and ergonomics evaluations to systematically identify the problems, prioritize the right ones, and develop effective and practical solutions. This paper gives an overview of the discipline of human factors and ergonomics and describes its role in improving patient safety. We provide examples of how human factors and ergonomics principles and methods have improved both care processes and patient outcomes. We provide five major recommendations to better integrate human factors and ergonomics in patient safety improvement efforts: build capacity among health care workers to understand human factors and ergonomics, create market forces that demand the integration of human factors and ergonomics design principles into medical technologies, increase the number of human factors and ergonomic practitioners in health care organizations, expand investments in improvement efforts informed by human factors and ergonomics, and support interdisciplinary research to improve patient safety. In conclusion, human factors and ergonomics must play a more prominent role in health care if we want to increase the pace in improving patient safety.

    We prepared and characterized golimumab (CNTO148), a human IgG1 tumor necrosis factor alpha (TNFα) antagonist monoclonal antibody chosen for clinical development based on its molecular properties. Golimumab was compared with infliximab, adalimumab and etanercept for affinity and in vitro TNFα neutralization. The affinity of golimumab for soluble human TNFα, as determined by surface plasmon resonance, was similar to that of etanercept (18 pM versus 11 pM), greater than that of infliximab (44 pM) and significantly greater than that of adalimumab (127 pM, p=0.018).  The concentration of golimumab necessary to neutralize TNFα-induced E-selectin expression on human endothelial cells by 50% was significantly less than those for infliximab (3.2 fold; p=0.017) and adalimumab (3.3-fold; p=0.008) and comparable to that for etanercept. The conformational stability of golimumab was greater than that of infliximab (primary melting temperature [Tm] 74.8 °C vs. 69.5 °C) as assessed by differential scanning calorimetry.  In addition, golimumab showed minimal aggregation over the intended shelf life when formulated as a high concentration liquid product (100 mg/mL) for subcutaneous administration.  In vivo, golimumab at doses of 1 and 10 mg/kg significantly delayed disease progression in a mouse model of human TNFα-induced arthritis when compared with untreated mice, while infliximab was effective only at 10 mg/kg. Golimumab also significantly reduced histological scores for arthritis severity and cartilage damage, as well as serum levels of pro-inflammatory cytokines and chemokines associated with arthritis. Thus, we have demonstrated that golimumab is a highly stable human monoclonal antibody with high affinity and capacity to neutralize human TNFα in vitro and in vivo.

    Executive Summary Despite advances in technology, power system operators must assimilate overwhelming amounts of data to keep the grid operating. Analyses of recent blackouts have clearly demonstrated the need to enhance the operator’s situation awareness (SA). The long-term objective of this research is to integrate valuable technologies into the grid operator environment that support decision making under normal and abnormal operating conditions and remove non-technical barriers to enable the optimum use of these technologies by individuals working alone and as a team. More specifically, the research aims to identify methods and principles to increase SA of grid operators in the context of system conditions that are representative or common across many operating entities and develop operationally relevant experimental methods for studying technologies and operational practices which contribute to SA. With increasing complexity and interconnectivity of the grid, the scope and complexity of situation awareness have grown. New paradigms are needed to guide research and tool development aimed to enhance and improve operations. In reviewing related research, operating practices, systems, and tools, the present study established a taxonomy that provides a perspective on research and development surrounding power grid situation awareness and clarifies the field of human factors/SA for grid operations. Information sources that we used to identify critical factors underlying SA included interviews with experienced operational personnel, available historical summaries and transcripts of abnormal conditions and outages (e.g., the August 14, 2003 blackout), scientific literature, and operational policies/procedures and other documentation. Our analysis of August 2003 blackout transcripts and interviews adopted a different perspective than previous analyses of this material, and we complemented this analysis with additional interviews. Based on our analysis and a broad

    Almost all the existing Nuclear Power Plants (NPPs) include plans to modernize their existing Instrumentation and Control (I and C) systems and associated Human System Interfaces (HSIs), due to obsolescence problems. Tecnatom, S.A. has been participating in modernization programs in NPPs to help them to plan, specify, design and implement the modernization of control rooms and associated I and C and HSIs. The application of Human Factors Engineering (HFE) in modernization programs is nowadays unavoidable. This is because is becoming a regulatory requirement, and also because it is needed to ensure that any plant modification, involving the modernization of I and C and HSI, is well designed to improve overall plant operations, reliability, and safety. This paper shows some experiences obtained during the application of HFE to the modernization of these HSIs. The experience applying HFE in modernizations and design modifications show a positive effect, improving the associated HSIs, with the acceptability of the final user.

    Full Text Available Carnosine is a naturally present dipeptide abundant in skeletal muscle and an over-the counter food additive. Animal data suggest a role of carnosine supplementation in the prevention and treatment of obesity, insulin resistance, type 2 diabetes and cardiovascular disease but only limited human data exists.Samples of vastus lateralis muscle were obtained by needle biopsy. We measured muscle carnosine levels (high-performance liquid chromatography, % body fat (bioimpedance, abdominal subcutaneous and visceral adiposity (magnetic resonance imaging, insulin sensitivity (euglycaemic hyperinsulinemic clamp, resting energy expenditure (REE, indirect calorimetry, free-living ambulatory physical activity (accelerometers and lipid profile in 36 sedentary non-vegetarian middle aged men (45±7 years with varying degrees of adiposity and glucose tolerance. Muscle carnosine content was positively related to % body fat (r = 0.35, p = 0.04 and subcutaneous (r = 0.38, p = 0.02 but not visceral fat (r = 0.17, p = 0.33. Muscle carnosine content was inversely associated with insulin sensitivity (r = -0.44, p = 0.008, REE (r = -0.58, p<0.001 and HDL-cholesterol levels (r = -0.34, p = 0.048. Insulin sensitivity and physical activity were the best predictors of muscle carnosine content after adjustment for adiposity.Our data shows that higher carnosine content in human skeletal muscle is positively associated with insulin resistance and fasting metabolic preference for glucose. Moreover, it is negatively associated with HDL-cholesterol and basal energy expenditure. Intervention studies targeting insulin resistance, metabolic and cardiovascular disease risk factors are necessary to evaluate its putative role in the prevention and management of type 2 diabetes and cardiovascular disease.

  9. Applying Human Factors during the SIS Life Cycle

    Safety Instrumented Systems (SIS) are widely used in U.S. Department of Energy's (DOE) nonreactor nuclear facilities for safety-critical applications. Although use of the SIS technology and computer-based digital controls, can improve performance and safety, it potentially introduces additional complexities, such as failure modes that are not readily detectable. Either automated actions or manual (operator) actions may be required to complete the safety instrumented function to place the process in a safe state or mitigate a hazard in response to an alarm or indication. DOE will issue a new standard, Application of Safety Instrumented Systems Used at DOE Nonreactor Nuclear Facilities, to provide guidance for the design, procurement, installation, testing, maintenance, operation, and quality assurance of SIS used in safety significant functions at DOE nonreactor nuclear facilities. The DOE standard focuses on utilizing the process industry consensus standard, American National Standards Institute/ International Society of Automation (ANSI/ISA) 84.00.01, Functional Safety: Safety Instrumented Systems for the Process Industry Sector, to support reliable SIS design throughout the DOE complex. SIS design must take into account human-machine interfaces and their limitations and follow good human factors engineering (HFE) practices. HFE encompasses many diverse areas (e.g., information display, user-system interaction, alarm management, operator response, control room design, and system maintainability), which affect all aspects of system development and modification. This paper presents how the HFE processes and principles apply throughout the SIS life cycle to support the design and use of SIS at DOE nonreactor nuclear facilities.

    Epidermal growth factor (EGF), a polypeptide hormone originally discovered in the mouse submaxillary gland, stimulates growth in a variety of tissues in several species. This hormone has recently been identified in human urine. A homologous RIA for human EGF (RIA-hEGF) has been developed. In general, levels were similar to those recently reported using a heterologous RIA system. Twenty-four-hour urinary excretion of RIA-hEGF by normal adult males and females was 63.0 +- 3.0 and 52.0 +- 3.5 (mean +- SE) ..mu..g/total vol, or 29.7 +- 1.1 and 39.8 +- 1.7 ..mu..g/g creatinine, respectively. Excretion by females taking oral contraceptives was significantly greater (60.1 +- 2.7 ..mu..g/g creatinine; P < 0.01) than that by females who were not. Recent evidence suggests the probable identity of hEGF and ..beta..-urogastrone, a potent inhibitor of gastric acid secretion. Adult males with active peptic ulcer disease appeared to have lower urinary RIA-hEGF excretion (22.9 +- 2.6 ..mu..g/g creatinine) than normal men, but this was not significant (P > 0.05). Several of those with very low values had histories of alcohol abuse. Excretion by patients with Cushing's syndrome was normal. Patients with psoriasis or recovering from major burns excreted both abnormally high and abnormally low levels of RIA-hEGF, with no obvious correlation to their clinical condition. There was no apparent diurnal or postprandial variation in urinary RIA-hEGF excretion by normal subjects. An excellent linear correlation was observed between RIA-hEGF and creatinine concentrations in each urine sample for each subject, suggesting that RIA-hEGF concentration in a random urine sample provides a valid index of 24-h RIA-hEGF excretion.

    Human being, namely. 'living' get involved in risk factor. Even if risk is limited to lethal danger, human history is coresponding with numberless risks from ancient up to today. For example, there is increase in risk of death by car-crash owing to get high efficiency in transfer. In Japan, the death toll by car-accident is about ten thousands per year constantly. State of deaths by car-accident not only include driver itself but cyclist and pedestrian. Death rate of both the cyclist and pedestrian amounts to 40% of all. In the age, rate of fracture as result of fall-down while walking is very high. It shows that the aged who give up driving and get out of danger car-crush are attacked the another accident as walkers. On type of danger, the decrease in risk of one-side come to increase in risk of other side. That is 'risk trade-off'. Examples of risk trade-off as above are numerous in environment. Acceptable death rate of various causes is about 10{sup -4} per year in generally. Flight accident happens on rare occasions (10{sup -7} per year in Japan, usually). Spite of insignificant probability, people fear by both reasons that the possibility of rescue is very few and the size of accident is enormous. In the cases of flight and nuclear power plant, estimated accidents is sever, but its probability is very small. Therefore, risk of annual deaths by accident must be considered as multiplication of size of risk (deaths per year) by probability (frequency per year). Obtained result by such analysis shall conduct to right risk perception and stable 'risk acceptance'. (author)

  12. Teleoperator hand controllers: A contextual human factors assessment

    1994-05-01

    This document provides a human factors assessment of controllers for use with remotely controlled manipulators deployed to remove hazardous waste from underground storage tanks. The analysis concentrates on controller technique (i.e., the broad class of hand controller) and not on details of controller ergonomics. Examples of controller techniques include, for example, direct rate control, resolved unilateral position control, and direct bilateral position control. Using an existing concept, the Tank Waste Retrieval Manipulator System, as a reference, two basic types of manipulators may be identified for this application. A long reach, gross-positioning manipulator (LRM) may be used to position a smaller manipulator or an end-effector within a work site. For a Long Reach Manipulator, which will have an enormous motion range and be capable of high end-effector velocity, it will be safest and most efficient to use a resolved rate control system. A smaller, dexterous manipulator may be used to perform handling work within a relatively small work site, (i.e., to complete tasks requiring near-human dexterity). For a Dexterous Manipulator, which will have a smaller motion range than the LRM and be required to perform more difficult tasks, a resolved bilateral position control system will be safest and most efficient. However, during some waste recovery tasks it may be important to support the users by restricting movements to a single plane or axis. This can be done with a resolved bilateral position control system by (1) using the master controller force output to restrict controller inputs or (2) switching the controller to a multiaxis rate control mode and using the force output to provide a spring return to center functionality.

    Deaths from colorectal cancer are often due to liver metastasis. Trefoil factor-3 (TFF3) is expressed by normal intestinal epithelial cells and its expression is maintained throughout the colon adenoma-carcinoma sequence. Our previous work demonstrated a correlation between TFF3 expression and metastatic potential in an animal model of colon cancer. The aim of this study was to determine whether TFF3 is expressed in human colon cancer liver metastasis (CCLM) and whether inhibiting TFF3 expression in colon cancer cells would alter their invasive potential in vitro. Human CCLMs were analyzed at the mRNA and protein level for TFF3 expression. Two highly metastatic rat colon cancer cell lines that either natively express TFF3 (LN cells) or were transfected with TFF3 (LPCRI-2 cells), were treated with two rat TFF3 siRNA constructs (si78 and si365), and analyzed in an in vitro invasion assay. At the mRNA and protein level, TFF3 was expressed in 17/17 (100%) CCLMs and 10/11 (91%) primary colon cancers, but not in normal liver tissue. By real time PCR, TFF3 expression was markedly inhibited by both siRNA constructs in LN and LPCRI-2 cells. The si365 and si78 constructs inhibited invasion by 44% and 53%, respectively, in LN cells, and by 74% and 50%, respectively, in LPCRI-2 cells. These results provide further evidence that TFF3 contributes to the malignant behavior of colon cancer cells. These observations may have relevance for designing new diagnostic and treatment approaches to colorectal cancer.

    CTC-binding factor (CTCF) is a DNA-binding protein of vertebrates that plays essential roles in regulating genome activity through its capacity to act as an enhancer blocker. We performed a yeast two-hybrid screen to identify protein partners of CTCF that could regulate its activity. Using full-length CTCF as bait we recovered Kaiso, a POZ-zinc finger transcription factor, as a specific binding partner. The interaction occurs through a C-terminal region of CTCF and the POZ domain of Kaiso. CTCF and Kaiso are co-expressed in many tissues, and CTCF was specifically co-immunoprecipitated by several Kaiso monoclonal antibodies from nuclear lysates. Kaiso is a bimodal transcription factor that recognizes methylated CpG dinucleotides or a conserved unmethylated sequence (TNGCAGGA, the Kaiso binding site). We identified one consensus unmethylated Kaiso binding site in close proximity to the CTCF binding site in the human 5' beta-globin insulator. We found, in an insulation assay, that the presence of this Kaiso binding site reduced the enhancer-blocking activity of CTCF. These data suggest that the Kaiso-CTCF interaction negatively regulates CTCF insulator activity.

    The aim of this study was to demonstrate how research on emotion in sport psychology might inform the field of human factors. Human factors historically has paid little attention to the role of emotion within the research on human-system relations. The theories, methods, and practices related to research on emotion within sport psychology might be informative for human factors because fundamentally, sport psychology and human factors are applied fields concerned with enhancing performance in complex, real-world domains. Reviews of three areas of theory and research on emotion in sport psychology are presented, and the relevancy of each area for human factors is proposed: (a) emotional preparation and regulation for performance, (b) an emotional trait explanation for risk taking in sport, and (c) the link between emotion and motor behavior. Finally, there are suggestions for how to continue cross-talk between human factors and sport psychology about research on emotion and related topics in the future. The relevance of theory and research on emotion in sport psychology for human factors is demonstrated. The human factors field and, in particular, research on human-system relations may benefit from a consideration of theory and research on emotion in sport psychology. Theories, methods, and practices from sport psychology might be applied usefully to human factors.
