    General problems associated with social impacts of radiology and decision making is discussed, as the main topics of the meeting. The problem of population is discussed living in areas contaminates with radioactive substances resulting from a major accident or from pest practices. This situation needs decision making process for initiating actions like relocation, resettlement or large-scale decontamination. The roles of various participants in this decision making process and in the communication with the public are considered. (R.P.)

    In this study, it was revealed that the designed worksheets were feasible to collect HRA data, especially in abnormal situations. The defined taxonomy of UAs was unambiguous to distinguish actions of operators and quantify the probabilities. It is widely recognized that reliability of operators are critical to complex socio-technical systems. For this reason, human reliability analysis (HRA), which aims to identify unsafe actions (UAs) that contribute to risks of the systems and assess the failure rates of the actions, has been conducted. Although many techniques of HRA have been developed and used in many years, many reports indicated lack of database for supporting empirical bases of HRA methods. Thus, there have been recent efforts to collect data about human reliability from plant experience, simulator experiment or qualification, and laboratory experiments. As one of these efforts, KAERI also established a guideline to collect information about human reliability and performance shaping factors from simulators. This guideline particularly presented a set of worksheets that allows comprehensively gathering objectively observable information in simulations of emergency situations. This paper reports the process and preliminary results of the data collection from the simulations of abnormal situations based on the developed worksheets in KAERI database guideline. We analyzed operator behaviors of the sixteen experiments for the two kinds of abnormal situations: RCP (reactor coolant pump) cyclone filter blockage and CDP (condensate pump) valve stuck. The UAs of operators were identified and quantified. Because the number of simulations was limited and data of various situations will be obtained continuously, it is uncertain to conclude the resulted probabilities. Based on the worksheet, operator behaviors in many different kinds of scenarios will be analyzed and the relations between human reliabilities and the observed factors will be also investigated.

    Full Text Available Four hundred seventy nine Peruvian students (188 mal e and 291 female rated the frequency of negative social emotions in themselves, in their neighborhood, and in the Peruvian society; and the frequency of anomalous daily situations. Verbal aggressions and gossiping obtained the highest averages in the evaluations of affects in the neighborhood, but solidarity was rated as high than the negative affects. In the Peruvian society, envy and physical aggression were rated asthe highest, and the positive affects obtained the smallest averages. To be a victim of an assault,to be cheated, and to be insulted obtained the highest averages in anomalous situations. Resentment and anger were the most salient negative affects.

    In the wake of an event in Fukushima, the importance of leadership that is able to increase responses and retain safety in unexpected accidents and disasters is emerged and it is increased interest in a systemic approach to leadership. Experts of international community urge to pay attention to humans and organizations because decision making, understanding the situation and communications affect the progress of accident significantly in the extreme condition. The individual as a leader should be able to carry out a central role to coordinate in the central, to take responsibility for ethical decisions, to earn the trust of employees by taking initiative, and to order by using empirical knowledge. However it is not desirable to limit the flexible response of the organization to the individual role of the leader. It should also be emphasized that leadership is a characteristic of the organization that is required by all levels in order to achieve the goal and it is important to develop the ability in organizational level. Therefore it is necessary to constantly modify situational awareness while interacting with the entire organization and all employees must carry out as a leader in the ever-changing field because the leader's recognition ability is limited. Also, leadership can function only through followership in ethical situations.

  5. A study on the operator's communication pattern characteristics under abnormal operating situation of nuclear power plants

    2008-01-01

    The quality of a probabilistic safety assessment (PSA) has become more important and a human reliability analysis (HRA) is known as a major contributor to the uncertainty of a PSA. As a part of enhancing the HRA quality, a study was initiated to find out characteristics of communication pattern and to evaluate communication quality of the operators of nuclear power plants. Korea Atomic Energy Research Institute (KAERI) is developing evaluation methods for the effect of human-induced events on risk/performance. This paper describes a study on the operator's communication pattern characteristics under abnormal operating situation of nuclear power plants. The study was carried out in four stages; 1) Video recording 2) Audio scripting 3) Message Classification 4) Communication Pattern Analysis. We recorded eight abnormal simulator training programs from Younggwang nuclear power plant training center. After that we performed message classification and carried out communication pattern analysis. We compared communication patterns of abnormal operating situation with emergency operating situation.As results of analysis, the role of SRO (senior reactor operator) under abnormal operating situation was decreased than the activities under emergency operating situation because each operator (reactor operator, turbine operator, safety supervisor) in main control room (MCR) performs the activity to control by himself with corresponding field engineers with his basic knowledge of the system. On the other hand, the operator's decision making processes and activities under abnormal operating situation were dramatically increased than the emergency operating situation. (authors)

  6. An abnormal situation modeling method to assist operators in safety-critical systems

    2015-01-01

    One of the main causes of accidents in safety-critical systems is human error. In order to reduce human errors in the process of handling abnormal situations that are highly complex and mentally taxing activities, operators need to be supported, from a cognitive perspective, in order to reduce their workload, stress, and the consequent error rate. Of the various cognitive activities, a correct understanding of the situation, i.e. situation awareness (SA), is a crucial factor in improving performance and reducing errors. Despite the importance of SA in decision-making in time- and safety-critical situations, the difficulty of SA modeling and assessment means that very few methods have as yet been developed. This study confronts this challenge, and develops an innovative abnormal situation modeling (ASM) method that exploits the capabilities of risk indicators, Bayesian networks and fuzzy logic systems. The risk indicators are used to identify abnormal situations, Bayesian networks are utilized to model them and a fuzzy logic system is developed to assess them. The ASM method can be used in the development of situation assessment decision support systems that underlie the achievement of SA. The performance of the ASM method is tested through a real case study at a chemical plant. - Highlights: • Bayesian networks are applied to represent operators’ mental models when confront with abnormal situations. • A fuzzy logic system is used to resemble operators’ generating assessment results for every abnormal situation. • A virtual plant user interface and a prototype based on proposed method are developed to simulate a real case

    In contrast with previous research, we separated the flowchart into a search phase of an AOP category and the phase of an AOP in order for the operators to informatively and efficiently find an AOP. Meanwhile, Kang et al. developed a technique to associate alarm response procedures from annunciated alarms and data related with their causes. The search engine in this system, however, associates complex abnormal situations with multiple alarms and considers multiple abnormal situations to be diagnosed. The developed system shows how some advanced digital functions can collaboratively enhance a human operator's cognition. We expect that improvements and integration of these kinds of functions into the instrument and control of an MCR will continue. When an abnormal situation occurs in a nuclear power plant, the operators in the main control room (MCR) diagnose the cause of the abnormal situation based on the occurring alarms. However, because there are many different alarms and abnormal operating procedures (AOPs) in an MCR, it is necessary to develop education techniques or diagnosis supporting tools for aiding operators to efficiently cope with abnormal situations. Owing to the recent development of new power plants and new human resources, the necessity of these techniques and tools has been magnified. There have been some efforts to support operators in diagnosing abnormal situations from annunciated alarms. This paper introduces an integrated system that not only educates operators but also aids operators in searching AOPs under actual situations. For the purpose of education, this system provides flowcharts to find an AOP from annunciated alarms and a mimic alarm window that displays annunciated alarms during a selected abnormal situation. For the purpose of aiding a real-time search, this system has a function that shows AOPs related to the inputted alarm data and calculates the similarity of the AOPs and the alarm data.

    1981-01-01

    A methodology for the study of human planning behavior in complex dynamic systems is presented and applied to the study of aircraft pilot behavior in normal, abnormal and emergency situations. The method measures the depth of planning, that is the level of detail employed with respect to a specific task, according to responses to a verbal questionnaire, and compares planning depth with variables relating to time, task criticality and the probability of increased task difficulty. In two series of experiments, depth of planning was measured on a five- or ten-point scale during various phases of flight in a HFB-320 simulator under normal flight conditions, abnormal scenarios involving temporary runway closure due to snow removal or temporary CAT-III conditions due to a dense fog, and emergency scenarios involving engine shut-down or hydraulic pressure loss. Results reveal a dichotomy between event-driven and time-driven planning, different effects of automation in abnormal and emergency scenarios and a low correlation between depth of planning and workload or flight performance.

    2010-07-01

    Team performance has been studied in many safety-critical organizations including aviation, nuclear power plant, offshore oil platforms and health organizations. This study looks into teamwork strategies that air traffic controllers employ to manage emergencies and abnormal situations. Two field studies were carried out in the form of observations of simulator training in emergency and unusual scenarios of novices and experienced controllers. Teamwork strategies covered aspects of team orientation and coordination, information exchange, change management and error handling. Several performance metrics were used to rate the efficiency of teamwork and test the construct validity of a prototype model of teamwork. This is a companion study to an earlier investigation of taskwork strategies in the same field (part I) and contributes to the development of a generic model for Taskwork and Teamwork strategies in Emergencies in Air traffic Management (T(2)EAM). Suggestions are made on how to use T(2)EAM to develop training programs, assess team performance and improve mishap investigations. Copyright 2010 Elsevier Ltd. All rights reserved.

    This paper describes the task of the technical advisers within the off-site emergency response organization in nuclear accident. They shall be collected and evaluated all influencing factors relevant in decision-making process. The major influencing objective factors are the results of radiological and economic consequence assessments. However, it is associated with uncertainties in predictions dependent of the phase of the accident. Important other factors emerge from subjective arguments between technical advisers in decision-making process. By theirs different opinions, the decision maker who is lack of experience and knowledge has a much more difficult to make and implement the emergency actions. Therefore, the practically considerations in a concrete emergency situation are timely implemented the emergency actions result from already existing plans. The actual process of decision-making consists in identifying in a iterative process implementing individual actions or a set of combined action

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society. We propose you of to know more about it in this file. (N.C.)

    Thirty-one individuals awaiting trial or sentencing for murder or undergoing an appeal process requested a neurologic examination through legal counsel. We attempted in each instance to obtain EEG, MRI or CT, and neuropsychological testing. Neurologic examination revealed evidence of "frontal" dysfunction in 20 (64.5%). There were symptoms or some other evidence of temporal lobe abnormality in nine (29%). We made a specific neurologic diagnosis in 20 individuals (64.5%), including borderline or full mental retardation (9) and cerebral palsy (2), among others. Neuropsychological testing revealed abnormalities in all subjects tested. There were EEG abnormalities in eight of the 20 subjects tested, consisting mainly of bilateral sharp waves with slowing. There were MRI or CT abnormalities in nine of the 19 subjects tested, consisting primarily of atrophy and white matter changes. Psychiatric diagnoses included paranoid schizophrenia (8), dissociative disorder (4), and depression (9). Virtually all subjects had paranoid ideas and misunderstood social situations. There was a documented history of profound, protracted physical abuse in 26 (83.8%) and of sexual abuse in 10 (32.3%). It is likely that prolonged, severe physical abuse, paranoia, and neurologic brain dysfunction interact to form the matrix of violent behavior.

    1986-01-01

    The Texas Low-Level Radioactive Waste Disposal Authority was formed in 1981 to address the Texas low-level radioactive waste problem consistent with the direction of P.L. 96-573. The Authority has completed technical tasks, including source term evaluations, preliminary conceptual designs, economic assessments, and long-range planning, and has work in progress on facility design, site selection, operating procedures, and licensing. Site selection has been the major technical activity and will be completed in 1987 after on-site evaluations of potential sites. The Authority expects to have its site licensed and operating in 1992. Texas has been the leader in site selection. Political concerns and the uncertainty of the national agenda led Texas policy makers to slow down the state's progress. The lessons learned through the Texas situation should be instructive to other states and compacts and may well be a prediction of events for these other groups. This paper discusses the background and status of Texas development activities, future plans, and lessons learned

  2. Communication and abnormal behaviour.

    Science.gov (United States)

    Crown, S

    1979-01-01

    In this paper the similarities between normal and abnormal behaviour are emphasized and selected aspects of communication, normal and aberrant, between persons are explored. Communication in a social system may be verbal or non-verbal: one person's actions cause a response in another person. This response may be cognitive, behavioural or physiological. Communication may be approached through the individual, the social situation or social interaction. Psychoanalysis approaches the individual in terms of the coded communications of psychoneurotic symptoms or psychotic behaviour; the humanist-existential approach is concerned more with emotional expression. Both approaches emphasize the development of individual identity. The interaction between persons and their social background is stressed. Relevant are sociological concepts such as illness behaviour, stigma, labelling, institutionalization and compliance. Two approaches to social interactions are considered: the gamesplaying metaphor, e.g. back pain as a psychosocial manipulation--the 'pain game'; and the 'spiral of reciprocal perspectives' which emphasizes the interactional complexities of social perceptions. Communicatory aspects of psychological treatments are noted: learning a particular metaphor such as 'resolution' of the problem (psychotherapy), learning more 'rewarding' behaviour (learning theory) or learning authenticity or self-actualization (humanist-existential).

The monitoring strategy developed was able to provide early alert mechanisms in the event of abnormal situations caused by abnormal patient arrivals to the ED. More specifically, This work proposed the application of autoregressive moving average (ARMA) models combined with the generalized likelihood ratio (GLR) test for anomaly-detection. ARMA was used as the modelling framework of the ARMA-based GLR anomaly-detection methodology. The GLR test was applied to the uncorrelated residuals obtained from the ARMA model to detect anomalies when the data did not fit the reference ARMA model. The ARMA-based GLR hypothesis testing scheme was successfully applied to the practical data collected from the database of the pediatric emergency department (PED) at Lille regional hospital center, France. © 2015 IEEE.

    1995-01-01

    Only components synchronized with rotation of pumps are sampled from detected acoustic sounds, to judge the presence or absence of abnormality based on the magnitude of the synchronized components. A synchronized component sampling means can remove resonance sounds and other acoustic sounds generated at a synchronously with the rotation based on the knowledge that generated acoustic components in a normal state are a sort of resonance sounds and are not precisely synchronized with the number of rotation. On the other hand, abnormal sounds of a rotating body are often caused by compulsory force accompanying the rotation as a generation source, and the abnormal sounds can be detected by extracting only the rotation-synchronized components. Since components of normal acoustic sounds generated at present are discriminated from the detected sounds, reduction of the abnormal sounds due to a signal processing can be avoided and, as a result, abnormal sound detection sensitivity can be improved. Further, since it is adapted to discriminate the occurrence of the abnormal sound from the actually detected sounds, the other frequency components which are forecast but not generated actually are not removed, so that it is further effective for the improvement of detection sensitivity.

  15. Operator training for the abnormal

    International Nuclear Information System (INIS)

    Marzec, R.J.

    1977-01-01

    Training of nuclear power plant control room operators, on actions to be taken for an abnormal event, has classically been limited to discussion, on-shift and/or during requalification training classes, of symptoms, logical thought processes, systems analysis, and operator experience. The prerequisites for these discussions are a common technical vocabulary, and a minimum basic comprehension of nuclear power plant fundamentals, plant component theory of operation, system configuration, system control philosophy and operating procedures. Nuclear power plant control room operators are not the only personnel who are or should be involved in these discussions. The shift supervisors, operations management, and auxiliary equipment operators require continuing training in abnormal operations, as well. More in-depth training is necessary for shift supervisors and control room operators. The availability of vendor simulators has improved the effectiveness of training efforts for these individuals to some extent by displaying typical situations and plant performance characteristics and by providing a degree of ''hands on'' experience. The evolution of in-depth training with these simulators is reviewed

  4. Management of abnormal radioactive wastes at nuclear power plants

    International Nuclear Information System (INIS)

    1989-01-01

    As with any other industrial activity, a certain level of risk is associated with the operation of nuclear power plants and other nuclear facilities. That is, on occasions nuclear power plants or nuclear facilities may operate under conditions which were not specifically anticipated during the design and construction of the plant. These abnormal conditions and situations may cause the production of abnormal waste, which can differ in character or quantity from waste produced during normal routine operation of nuclear facilities. Abnormal waste can also occur during decontamination programmes, replacement of a reactor component, de-sludging of storage ponds, etc. The management of such kinds of waste involves the need to evaluate existing waste management systems in order to determine how abnormal wastes should best be handled and processed. There are no known publications on this subject, and the IAEA believes that the development and exchange of such information among its Member States would be useful for specialists working in the waste management area. The main objective of this report is to review existing waste management practices which can be applied to abnormal waste and provide assistance in the selection of appropriate technologies and processes that can be used when abnormal situations occur. Naturally, the subject of abnormal waste is complex and this report can only be considered as a guide for the management of abnormal waste. Refs, figs and tabs.

    1991-01-01

    When an operator hears sounds in a plantsite, the operator compares normal sounds of equipment which he previously heard and remembered with sounds he actually hears, to judge if they are normal or abnormal. According to the method, there is a worry that abnormal conditions can not be appropriately judged in a case where the number of objective equipments is increased and in a case that the sounds are changed gradually slightly. Then, the device of the present invention comprises a plurality of monitors for monitoring the operation sound of equipments, a recording/reproducing device for recording and reproducing the signals, a selection device for selecting the reproducing signals among the recorded signals, an acoustic device for converting the signals to sounds, a switching device for switching the signals to be transmitted to the acoustic device between to signals of the monitor and the recording/reproducing signals. The abnormality of the equipments can be determined easily by comparing the sounds representing the operation conditions of equipments for controlling the plant operation and the sounds recorded in their normal conditions.

  10. Abnormal pressures as hydrodynamic phenomena

    Science.gov (United States)

    Neuzil, C.E.

    1995-01-01

    So-called abnormal pressures, subsurface fluid pressures significantly higher or lower than hydrostatic, have excited speculation about their origin since subsurface exploration first encountered them. Two distinct conceptual models for abnormal pressures have gained currency among earth scientists. The static model sees abnormal pressures generally as relict features preserved by a virtual absence of fluid flow over geologic time. The hydrodynamic model instead envisions abnormal pressures as phenomena in which flow usually plays an important role. This paper develops the theoretical framework for abnormal pressures as hydrodynamic phenomena, shows that it explains the manifold occurrences of abnormal pressures, and examines the implications of this approach. -from Author

  11. The effectiveness of airline pilot training for abnormal events.

    Casner, Stephen M; Geven, Richard W; Williams, Kent T

    2013-06-01

    To evaluate the effectiveness of airline pilot training for abnormal in-flight events. Numerous accident reports describe situations in which pilots responded to abnormal events in ways that were different from what they had practiced many times before. One explanation for these missteps is that training and testing for these skills have become a highly predictable routine for pilots who arrive to the training environment well aware of what to expect. Under these circumstances, pilots get plentiful practice in responding to abnormal events but may get little practice in recognizing them and deciding which responses to offer. We presented 18 airline pilots with three abnormal events that are required during periodic training and testing. Pilots were presented with each event under the familiar circumstances used during training and also under less predictable circumstances as they might occur during flight. When presented in the routine ways seen during training, pilots gave appropriate responses and showed little variability. However, when the abnormal events were presented unexpectedly, pilots' responses were less appropriate and showed great variability from pilot to pilot. The results suggest that the training and testing practices used in airline training may result in rote-memorized skills that are specific to the training situation and that offer modest generalizability to other situations. We recommend a more complete treatment of abnormal events that allows pilots to practice recognizing the event and choosing and recalling the appropriate response. The results will aid the improvement of existing airline training practices.

    2017-06-01

    Full Text Available The ultimate goal of a company is to build the enterprise value, which is achievable thanks to abnormal profits generated in particular period. Moreover, firms are expected to take measures to maintain abnormal profit in the future. On the other hand, abnormal profits attract competitors, who increase competition and as a result abnormal profits disappear. The persistence of profit is a term that describes a situation, when the company is successful in maintaining the abnormal profit over time. The main aim of this paper is to investigate the persistence of abnormal profit in Polish manufacturing sector. In other words, the question is whether Polish manufacturing companies are able to maintain their abnormal profits over time. The persistence of abnormal profits is investigated using dynamic panel model with generalized method-of-moments estimators. The method is applied to a panel of 5303 Polish companies from manufacturing sector observed over the period 2006-2014. This paper contributes to the existing literature in two ways. First, analysis is performed for developing country. Second, analysis is performed both at the level of entire sector and at division level. Three main conclusions can be drawn from the conducted research: there are significant differences between profit rates within the same industry at division level; estimated persistence of abnormal profit coefficients are at moderate level; there are substantial differences between estimated persistence of profit coefficients for divisions in the same industry.

    Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. A literature review was conducted on Medline considering the articles listed until January 2012. Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

  19. Situational theory of leadership.

    Waller, D J; Smith, S R; Warnock, J T

    1989-11-01

    The situational theory of leadership and the LEAD instruments for determining leadership style are explained, and the application of the situational leadership theory to the process of planning for and implementing organizational change is described. Early studies of leadership style identified two basic leadership styles: the task-oriented autocratic style and the relationship-oriented democratic style. Subsequent research found that most leaders exhibited one of four combinations of task and relationship behaviors. The situational leadership theory holds that the difference between the effectiveness and ineffectiveness of the four leadership styles is the appropriateness of the leader's behavior to the particular situation in which it is used. The task maturity of the individual or group being led must also be accounted for; follower readiness is defined in terms of the capacity to set high but attainable goals, willingness or ability to accept responsibility, and possession of the necessary education or experience for a specific task. A person's leadership style, range, and adaptability can be determined from the LEADSelf and LEADOther questionnaires. By applying the principles of the situational leadership theory and adapting their managerial styles to specific tasks and levels of follower maturity, the authors were successful in implementing 24-hour pharmacokinetic dosing services provided by staff pharmacists with little previous experience in clinical services. The situational leadership model enables a leader to identify a task, set goals, determine the task maturity of the individual or group, select an appropriate leadership style, and modify the style as change occurs. Pharmacy managers can use this model when implementing clinical pharmacy services.

    Roentgenograms of 28 patients with Down's syndrome were reviewed with emphasis on all previously reported abnormalities and any possible additional ones. Most of the abnormalities occurred with the same frequency as previously reported, but some less frequently reported findings were also seen. One abnormal vertebral measurement found in this series may be an additional stigma of Down's syndrome. All of the 27 cases studied cytogenetically had chromosomal abnormalities consistent with this disease. This study emphasizes the need for roentgenologic norms for the Japanese, and the desirability of combining chromosome studies with roentgenological abnormalities and clinical observations in diagnosing Down's syndrome. 19 references, 2 figures, 5 tables.

  19. Ictal Cardiac Ryhthym Abnormalities.

    Science.gov (United States)

    Ali, Rushna

    2016-01-01

    Cardiac rhythm abnormalities in the context of epilepsy are a well-known phenomenon. However, they are under-recognized and often missed. The pathophysiology of these events is unclear. Bradycardia and asystole are preceded by seizure onset suggesting ictal propagation into the cortex impacting cardiac autonomic function, and the insula and amygdala being possible culprits. Sudden unexpected death in epilepsy (SUDEP) refers to the unanticipated death of a patient with epilepsy not related to status epilepticus, trauma, drowning, or suicide. Frequent refractory generalized tonic-clonic seizures, anti-epileptic polytherapy, and prolonged duration of epilepsy are some of the commonly identified risk factors for SUDEP. However, the most consistent risk factor out of these is an increased frequency of generalized tonic-clonic seizures (GTC). Prevention of SUDEP is extremely important in patients with chronic, generalized epilepsy. Since increased frequency of GTCS is the most consistently reported risk factor for SUDEP, effective seizure control is the most important preventive strategy.

We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

    Three experimentally naive abnormal children were exposed to a terminal operant contingency, i.e., reinforcement was delivered only if the children pressed a panel during intervals when it was lighted. Despite the absence of both successive approximation and manual shaping, it was found that each child began to respond discriminatively within a small number of trials. These data replicated previous animal studies concerned with the phenomena of autoshaping and signal-controlled responding. It was also found, however, that one type of autoshaping, the classical conditioning procedure, had a powerful suppressive effect on the discriminative responding. An experimental analysis that consisted procedure, had a powerful suppressive effect on discriminative responding. An experimental analysis that consisted of intrasubject reversal an multiple baseline designs established the internal validity of the findings. The finding of rapid acquisition of signal-controlled responding obtained with the initial procedure is suggessted to have practical significance. The disruptive effects of the classical form of autoshaping are discussed in terms of negative behavioral contrast.

  8. Management Re-situated

    DEFF Research Database (Denmark)

    Lystbæk, Christian Tang

    The purpose of this paper is to examine ways to situate management within philosophy, that is, ways to analyze the philosophical assumptions in management history, theory and practice. Since Burrell and Morgan suggested the idea that “all theories of organization are based upon philosophy...... of science“ (Burrell & Morgan, 1979:1), philosophical reflections in terms of a series of “isms” informed by different schools or paradigms (such as positivism, structuralism, phenomenology, critical theory, and so on and so forth) have been a central part of management studies. Thus, today, it has become...... common sense to categorize different approaches to management according to their assumptions of ontology, epistemology and methodology. My paper will argue first (1) that, although sometimes very abstract and obtuse writing that seems to owe more to competition among academics than to illumination...

    Considerations related to the early planning for the International Magnetospheric Study (IMS) took into account the desirability of an establishment of specific entities for generating and disseminating coordination information for both retrospective and predictive periods. The organizations established include the IMS/Satellite Situation Center (IMS/SSC) operated by NASA. The activities of the SSC are related to the preparation of reports on predicted and actually achieved satellite positions, the response to inquiries, the compilation of information on satellite experiments, and the issue of periodic status summaries. Attention is given to high-altitude satellite services, other correlative satellite services, non-IMS activities of the SSC, a summary of the SSC request activity, and post-IMS and future activities

    To determine in a cross-sectional study the prevalence of electrocardiographic (ECG) abnormalities in opiate addicts who were therapy-seeking and its association with demographic, clinical and drug-specific parameters. In consecutive therapy-seeking opiate addicts, a 12-lead ECG was registered within 24 hours after admission and evaluated according to a pre-set protocol between October 2004 and August 2006. Additionally, demographic, clinical and drug-specific parameters were recorded. Included were 511 opiate-addicts, 25% female, with a mean age of 29 years (range 17-59 years). One or more ECG abnormalities were found in 314 patients (61%). In the 511 patients we found most commonly ST abnormalities (19%), QTc prolongation (13%), tall R- and/or S-waves (11%) and missing R progression (10%). ECG abnormalities were more common in males than in females (64 versus 54%, P seizures less often (16 versus 27%, P opiate addicts. The most frequent ECG abnormalities are ST abnormalities, QTc prolongation and tall R- and/or S-waves. ST abnormalities are associated with cannabis, and QTc prolongation with methadone and benzodiazepines.

    Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis. We present among others characteristic radiographic findings of hemangioma, chondrosarcoma, hydatid disease, and SAPHO syndrome. In those cases in which findings are not specific, cross-sectional imaging modalities may help the clinician in their management. (orig.)

    Full Text Available In this paper we analyzed the cirumstances of every day life which requires the need to adapt the leadership style. Leadership needs a lot of abilities and skills, including the capability to communicate. The paper deals with leader’s need of changing the style of leading as organizational circumstances change. The process is efficient only when the leaders and the followers have the right climate. The importance of this process is reflected in the productivity of the organization. As the economic climate changes the leadership style needs to be changed and also the style of communication throughout the leader coaches, coordinates, evaluates and supervises. Leadership is about organizing a group of people to achieve a goal. The leader may or may not have any formal authority. Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. This paper describes the styles of leadership which the leaders must use and switch when is needed in comparison with what leadership is about.

    2012-03-01

    The aim of this study was to use quantitative sensory testing (QST) to explore the range and prevalence of somatosensory abnormalities demonstrated by patients with advanced knee OA. One hundred and seven knee OA patients and 50 age- and sex-matched healthy participants attended a 1-h QST session. Testing was performed on the medial side of the knee and the pain-free forearm. Light-touch thresholds were assessed using von Frey filaments, pressure pain thresholds using a digital pressure algometer, and thermal sensation and pain thresholds using a Thermotest MSA. Significant differences in median threshold values from knee OA patients and healthy participants were identified using Mann-Whitney U-tests. The z-score transformations were used to determine the prevalence of the different somatosensory abnormalities in knee OA patients. Testing identified 70% of knee OA patients as having at least one somatosensory abnormality. Comparison of median threshold values between knee OA patients and healthy participants revealed that patients had localized thermal and tactile hypoaesthesia and pressure hyperalgesia at the osteoarthritic knee. Tactile hypoaesthesia and pressure hyperalgesia were also present at the pain-free forearm. The most prevalent somatosensory abnormalities were tactile hypoaesthesia and pressure hyperalgesia, evident in between 20 and 34% of patients. This study found that OA patients demonstrate an array of somatosensory abnormalities, of which the most prevalent were tactile hypoaesthesia and pressure hyperalgesia. Further research is now needed to establish the clinical implications of these somatosensory abnormalities.

  18. Screening human populations for abnormal radiosensitivity

    International Nuclear Information System (INIS)

    Gentner, N.E.; Morrison, D.P.

    1990-07-01

    A relatively rapid and inexpensive in vitro growback assay was developed that uses the irradiated versus the unirradiated re-growth responses of lymphoblastoid cell lines developed from individual donors as an estimator of donor radioresponse. The purpose of this project was to furnish an estimate of the proportion of strains derived from various study populations that may be regarded as exhibiting abnormal radioresponse. The emphasis in this study was on hypersensitivity, because of the known radiation-hypersensitivity and cancer proneness associated with the genetic disorder ataxia-telangiectasia. Using methods developed especially for survival analyses, the percentage of significantly hypersensitive responses was 5.5% in a donor population composed of ostensibly normal individuals. We also examined lines derived from an unselected cancer patient population. These were not enriched, compared to the reference normal population, for hypersensitive responses. We thus conclude that hypersensitivity in vitro is not associated with increased risk for spontaneous development of cancer. However, the failure to observe an association between hypersensitivity and spontaneous cancer does not preclude a correlation between such sensitivity and radiogenic cancer. At the present stage, we would caution against the application of this assay or related in vitro tests to the situation of an individual, as opposed to a population. While we have clear indications that hypersensitivity in vitro is associated with abnormal radioresponse in vivo, this study has identified sources of variation that must be understood before attempts are made to unambiguously attribute a particular type of radioresponse to an individual

    2010-11-01

    Disaster relief can be seen as a dynamic multi actor process with actors both joining and leaving the relief work during the help and rescue phase after the disaster has occurred. Actors may be governmental agencies, non profit voluntary organisations or spontaneous helpers comprised of individual citizens or temporal groups of citizens. Hence, they will vary widely in agility, competence, resources, and endurance. To prepare for for disasters a net based Agora with simulation of emergency situations for mutual preparation, training, and organisational learning is suggested. Such an Agora will ensure future security by: -Rising awareness and preparedness of potential disaster responders by help of the components and resources in the netAgora environment; -Improving cooperation and coordination between responders; -Improving competence and performance of organisations involved in security issues; -Bridging cultural differences between responders from different organizations and different backgrounds. The developed models are intended to reflect intelligent anticipatory systems for human operator anticipation of future consequences. As a way to catch what should be included in this netbased Agora and to join the split pictures that is present, Team Syntegrity could be a helpful tool. The purpose of Team Syntegrity is to stimulate collaboration and incite cross fertilization and creativity. The difference between syntegration and other group work is that the participants are evenly and uniquely distributed and will collectively have the means, the knowledge, the experience, the perspectives, and the expertise, to deal with the topic. In this paper the possibilities with using Team Syntegrity in preparation for the development of a netbased Agora is discussed. We have identified that Team Syntegrity could be useful in the steps User Integration, Designing the netAgora environment, developing Test Scenarios, and assessment of netAgora environment.

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

  1. Memetics clarification of abnormal behavior

    AIM: Biological medicine is hard to fully and scientifically explain the etiological factor and pathogenesis of abnormal behaviors; while, researches on philosophy and psychology (including memetics) are beneficial to better understand and explain etiological factor and pathogenesis of abnormal behaviors. At present, the theory of philosophy and psychology is to investigate the entity of abnormal behavior based on the views of memetics.METHODS: Abnormal behavior was researched in this study based on three aspects, including instinctive behavior disorder, poorly social-adapted behavior disorder and mental or body disease associated behavior disorder. Most main viewpoints of memetics were derived from "The Meme Machine", which was written by Susan Blackmore. When questions about abnormal behaviors induced by mental and psychological diseases and conduct disorder of teenagers were discussed, some researching achievements which were summarized by authors previously were added in this study, such as aggressive behaviors, pathologically aggressive behaviors, etc.RESULTS: The abnormal behaviors mainly referred to a part of people's substandard behaviors which were not according with the realistic social environment, culture background and the pathologic behaviors resulted from people's various psychological diseases. According to the theory of "meme", it demonstrated that the relevant behavioral obstacles of various psychological diseases, for example, the unusual behavior of schizophrenia, were caused, because the old meme was destroyed thoroughly but the new meme was unable to establish; psychoneurosis and personality disorder were resulted in hard establishment of meme; the behavioral obstacles which were ill-adapted to society, for example, various additional and homosexual behaviors, were because of the selfish replications and imitations of "additional meme" and "homosexual meme"; various instinct behavioral and congenital intelligent obstacles were not significance

    Overcrowding is one of the most crucial issues confronting emergency departments (EDs) throughout the world. Efficient management of patient flows for ED services has become an urgent issue for most hospital administrations. Handling and detection of abnormal situations is a key challenge in EDs. Thus, the early detection of abnormal patient arrivals at EDs plays an important role from the point of view of improving management of the inspected EDs. It allows the EDs mangers to prepare for high levels of care activities, to optimize the internal resources and to predict enough hospitalization capacity in downstream care services. This study reports the development of statistical method for enhancing detection of abnormal daily patient arrivals at the ED, which able to provide early alert mechanisms in the event of abnormal situations. The autoregressive moving average (ARMA)-based exponentially weighted moving average (EWMA) anomaly detection scheme proposed was successfully applied to the practical data collected from the database of the pediatric emergency department (PED) at Lille regional hospital center, France.

For this reason, ESO has until now been silent in these matters, but we have now become obliged to make our opinion known". The ESO representative also made it clear, that "ESO does not question the rights of the claimants to recur to the Chilean Tribunals which must decide on the matter of ownership, and that ESO cannot be party to this lawsuit". He added that "ESO fully trusts that the Chilean Government will do whatever is necessary to defend the immunity of ESO". THE CURRENT SITUATION During the past few days, declarations from high officials at the Chilean Ministry of Foreign Affairs have been made which clearly confirm ESO's immunity of jurisdiction from Chilean Courts. The same opinion has been ventured by Chilean experts in international law, quoted in various Chilean newspapers. On Friday, February 17, the Chilean Minister of Foreign Affairs, Mr. Jose M. Insulza, made a similar, very eloquent statement. ESO welcomes these articulate expressions that support its official position and trusts that the current situation will be speedily resolved by the competent Chilean authorities, so that the construction work at Paranal will not be stopped. During the past three decades, ESO's presence in Chile has been characterised by good relations to all sides. The development of astronomy in Chile during the past decades has reached such a level that it will now benefit from a new quality of cooperation. In addition to its past and numerous services to Chilean astronomy, ESO has recently considered to establish a "guaranteed" observing time for astronomers from this country, both at La Silla and the future VLT observatory on Paranal. With a proposed 10 percent quota for the VLT, Chilean astronomers will in fact have free access to the equivalent of 40 percent of one 8.2-metre telescope; the associated, not insignificant cost is entirely carried by ESO. ESO has also considered to incorporate

    Operating complex plants is an increasingly demanding task for human operators. Diagnosis of and reaction to on-line events requires the interpretation of real time data. Vast amounts of sensor data as well as operational knowledge about the state and design of the plant are necessary to deduct reasonable reactions to abnormal situations. Intelligent computational support tools can make the operator’s task easier, but they require knowledge about the overall system in form of some model. While tools used for fault-tolerant control design based on physical principles and relations are valuable tools for designing robust systems, the models become too complex when considering the interactions on a plant-wide level. The alarm systems meant to support human operators in the diagnosis of the plant-wide situation on the other hand fail regularly in situations where these interactions of systems lead to many related alarms overloading the operator with alarm floods. Functional modelling can provide a middle way to reduce the complexity of plant-wide models by abstracting from physical details to more general functions and behaviours. Based on functional models the propagation of failures through the interconnected systems can be inferred and alarm floods can potentially be reduced to their root-cause. However, the desired behaviour of a complex system changes due to operating procedures that require more than one physical and functional configuration. In this paper a consistent representation of possible configurations is deduced from the analysis of an exemplary start-up procedure by functional models. The proposed interpretation of the modelling concepts simplifies the functional modelling of distinct modes. The analysis further reveals relevant links between the quantitative sensor data and the qualitative perspective of the diagnostics tool based on functional models. This will form the basis for the ongoing development of a novel real-time diagnostics system based

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society. We propose you of to know more about it in this file. (N.C.)

    As a consequence of the Chernobyl accident the need for better communication and cooperation between the countries of Nordic Europe (Denmark, Finland, Iceland, Norway and Sweden) in case of nuclear accidents became increasingly obvious. An initiative in this direction was taken by the Nordic Liaison Committee for Atomic Energy (NKA), a intergovernmental body responsible for cooperation in the Nuclear field, established by the Nordic Council. Thus, the Nordic Contact Forum became a reality. The Forum was created to serve as an informal network among nuclear experts, information officers and journalists in the Nordic countries. The network has been held together by a committee consisting of one representative from each country, as appointed by the Governments. The Nordic Contact Forum arranged the first of three seminars for representatives of public authorities, the nuclear industry, and journalists in 1988 in Vikersund, Norway. The Forum also has established a network among information officers for the exchange of information of public interest within the nuclear field. As a result of its work and agreement has been reached as to when and how this information is to be disseminated, and lists of contact points have been drawn up. This will make it easier to give the public in each of the Nordic countries better an, above all, better coordinated information. The existence of this network has had positive results. Thus, on several occasions false rumours of nuclear accidents, radioactive clouds, etc, have been neutralized before they have caused unnecessary public concern. (au)

Myasthenia gravis was present in 6 cases (16%) of thymic abnormalities, four (10,5%) with invasive thymoma and two (5%) with thymic hyperplasia. Graves' disease was also present in one case of thymic hyperplasia. We emphasize the contribution of CT to the diagnosis and the prognosis.

    Hearing loss and otitis media are commonly associated with Down syndrome. Hypoplasia of the mastoids is seen in many affected children and sclerosis of mastoid bones is not uncommon in Down syndrome. Awareness and early recognition of mastoid abnormality may lead to appropriate and timely therapy, thereby preserving the child's hearing or compensating for hearing loss; factors which are important for learning and maximum development.

    Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office or primary-care setting. The wider availability of diagnostic tools has allowed prompt diagnosis and treatment of an increasing number of menstrual disorders in an office setting. This White Paper reviews the advantages and disadvantages of transvaginal ultrasound, blind endometrial sampling and diagnostic hysteroscopy. Once a proper diagnosis has been established, appropriate therapy may be embarked upon. Fortunately, only a minority of such patients will have premalignant or malignant disease. When bleeding is sufficient to cause severe anemia or even hypovolemia, prompt intervention is called for. In most of the cases, however, the abnormal uterine bleeding will be disquieting to the patient and significantly affect her 'quality of life'. Sometimes, reassurance and expectant management will be sufficient in such patients. Overall, however, in cases of benign disease, some intervention will be required. The use of oral contraceptive pills especially those with a short hormone-free interval, the insertion of the levonorgestrel intrauterine system, the incorporation of newer medical therapies including antifibrinolytic drugs and selective progesterone receptor modulators and minimally invasive treatments have made outpatient therapy increasingly effective. For others, operative hysteroscopy and endometrial ablation are proven therapeutic tools to provide both long- and short-term relief of abnormal uterine bleeding, thus avoiding, or deferring, hysterectomy.

    A bleeding diathesis is a common feature of Noonan syndrome, and various coagulation abnormalities have been reported. Platelet function has never been carefully investigated. The degree of bleeding diathesis in a cohort of patients with Noonan syndrome was evaluated by a validated bleeding score and investigated with coagulation and platelet function tests. If ratios of prothrombin time and/or activated partial thromboplastin time were prolonged, the activity of clotting factors was measured. Individuals with no history of bleeding formed the control group. The study population included 39 patients and 28 controls. Bleeding score was ≥2 (ie, suggestive of a moderate bleeding diathesis) in 15 patients (38.5%) and ≥4 (ie, suggestive of a severe bleeding diathesis) in 7 (17.9%). Abnormal coagulation and/or platelet function tests were found in 14 patients with bleeding score ≥2 (93.3%) but also in 21 (87.5%) of those with bleeding score Noonan syndrome had a bleeding diathesis and >90% of them had platelet function and/or coagulation abnormalities. Results of these tests should be taken into account in the management of bleeding or invasive procedures in these patients. Copyright © 2014 by the American Academy of Pediatrics.

    1987-10-01

    Although much time, effort, and money have been expended in the area of fetal surgery and even though considerable unfortunate media publicity has resulted, the actual clinical problem is not one of great magnitude. Currently all those interested in this area agree that consideration of any intrauterine manipulation or surgery should be reserved for a fetus who has bilateral involvement that is progressive, destructive, and associated with oligohydramnios. Except for rare instances, this eliminates all fetuses except those with some type of urethral obstruction. Significant urethral obstruction accounts for approximately 10 per cent of all patients who have a prenatal diagnosis of a urologic abnormality. Of this 10 per cent, some will not be progressive, some will not be destructive, some will not involve both kidneys, and some will not develop oligohydramnios. Some of these patients will be diagnosed early enough in pregnancy to allow termination of the pregnancy if the involvement is significant and if termination is acceptable to the family. Some will be diagnosed late enough in pregnancy so that if the lungs are mature or can be stimulated to mature, early delivery and postnatal management can be elected. Some will have other associated lethal anomalies that can be diagnosed and would preclude any consideration of intrauterine manipulation or therapy. Some will have irreversible renal failure. Occasionally, the mother may refuse any proposed intrauterine therapy. Thus we are probably considering, on a theoretic basis, well under 1 per cent of all fetuses who have a prenatal diagnosis of urologic abnormalities. There may be some unusual situations that justify intrauterine manipulation. One that we encountered involved a fetus with an abdominal mass so large that a cesarean section was deemed necessary (Figs. 12 and 13). Aspiration of the mass just before delivery was performed to allow a vaginal delivery. Another case involved a pregnant woman who developed

    Energy Technology Data Exchange (ETDEWEB)

    Utsunomiya, Kazuhiro; Oyama, Shinmi; Sakaba, Hideo

    1989-02-21

    According to the present invention, abnormality such as abnormal increase of temperature in a nuclear reactor is detected to send a signal to control rod drives, etc. thereby stopping the operation of the nuclear reactor. Receiving/transmission device transmits a signal for conducting normal operation of an abnormality information section, as well as receives an echo signal from the abnormality information section to transmit an abnormal signal to a reactor protection system. The abnormality information section is disposed to fuel assemblies, receives a signal from the receiving/transmission device for conducting the normal operation to transmit a normal echo signal, as well as changes the echo signal when detecting the nuclear reactor abnormality. By the foregoing method, since the abnormality information section is disposed to the fuel assemblies, various effects can be attained such as: (1) there is no response delay from the occurrence of abnormality to emergency counter measure after detection, (2) high burnup degree for fuels can thus be possible to improve the economical property, (3) the abnormality information section can be taken out from the reactor container together with fuel assemablies by an existent take-out mechanism and (4) since wireless transmission and reception are established between the receiving/transmission device and the abnormality information section, cables are not required in the container.

  5. [Support psychotherapy in traumatic situations].

    Science.gov (United States)

    Pérez-Sales, Pau; Vázquez Valverde, Carmelo

    2003-12-01

    It seems that a certain consensus exists to speak about a traumatic situation as an experience which is made up of a threat on the physical or psychological integrity of a person and against which one responds with fear, desperation and intensive horror. Different psychological phenomena are involved with the manner through which a human being confronts his/her past. In particular, the response to traumatic situations, mourning, and blame share their characteristic of being an irreversible living reality related to facts, loss or past impacts and it is necessary to integrate these in one's life in order to advance; these comprise a triangle frequently coexisting and interconnected. Aid for these three situations has, therefore, as common elements, two premises: an active task is required by the person who suffers this situation; this person must, in some form, desire to move ahead. One can not toil in mourning, in a traumatic experience, or in a life of blame if these have a positive symbolic value for this person; for example, mourning as a manner not to treason the dead person by forgetting that person, the reliving a trauma as an attempt to provide some sense to the actions which occurred, or blame as a desire to not forget an error or as a final punishment of this active task; the final objective of this active task is not usually to forget but to integrate in order to live. If a person does not perceive this clearly, this person may not become actively involved in the task to overcome a traumatic situation and to move ahead, nor will that person accept that a person who tries to help questions this person's realities or experiences.

    Full Text Available We test the hypothesis that strategies which are long on portfolios of looser stocks and short on portfolios of winner stocks generate abnormal returns in Brazil. This type of evidence for the US stock market was interpreted by The Bondt and Thaler (1985 as reflecting systematic evaluation mistakes caused by investors overreaction to news related to the firm performance. We found evidence of contrarian strategies profitability for horizons from 3 months to 3 years in a sample of stock returns from BOVESPA and SOMA from 1986 to 2000. The strategies are more profitable for shorter horizons. Therefore, there was no trace of the momentum effect found by Jagadeesh and Titman (1993 for the same horizons with US data. There are remaing unexplained positive returns for contrarian strategies after accounting for risk, size, and liquidity. We also found that the strategy profitability is reduced after the Real Plan, which suggests that the Brazilian stock market became more efficient after inflation stabilization.

  12. Situation awareness system for Canada

    Science.gov (United States)

    Hill, Andrew

    1999-07-01

    Situation awareness encompasses a knowledge of orders, plans and current knowledge of friendly force actions. Knowing where you are and being able to transmit that information in near real-time to other friendly forces provides the ability to exercise precise command and control over those forces. With respect to current command and control using voice methods, between 40 percent and 60 percent of Combat Net Radio traffic relates to location reporting of some sort. Commanders at Battle Group and below spend, on average, 40 percent of their total time performing position and navigation related functions. The need to rapidly transfer own force location information throughout a force and to process the received information quickly, accurately and reliably provides the rationale for the requirement for an automated situation awareness system. This paper describes the Situation Awareness System (SAS) being developed by Computing Devices Canada for the Canadian Department of National Defence as a component of the Position Determination and Navigation for Land Forces program. The SAS is being integrated with the Iris Tactical Command, Control, Communications System, which is also being developed by Computing Devices. The SAS software provides a core operating environment onto which command and control functionality can be easily added to produce general and specialist battlefield management systems.

  13. Harmful situations, impure people: an attribution asymmetry across moral domains.

    Science.gov (United States)

    Chakroff, Alek; Young, Liane

    2015-03-01

    People make inferences about the actions of others, assessing whether an act is best explained by person-based versus situation-based accounts. Here we examine people's explanations for norm violations in different domains: harmful acts (e.g., assault) and impure acts (e.g., incest). Across four studies, we find evidence for an attribution asymmetry: people endorse more person-based attributions for impure versus harmful acts. This attribution asymmetry is partly explained by the abnormality of impure versus harmful acts, but not by differences in the moral wrongness or the statistical frequency of these acts. Finally, this asymmetry persists even when the situational factors that lead an agent to act impurely are stipulated. These results suggest that, relative to harmful acts, impure acts are linked to person-based attributions. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available In this study, 44 patients with liver cirrhosis were investigated for hemostatic parameters. Patients with spontaneous bacterial peritonitis, hepatocellular carcinoma, hepatorenal syndrome and cholestatic liver diseases were excluded. Patients were classified by Child-Pugh criterion and according to this 4 patients were in Class A, 20 in Class B and 20 in C. Regarding to these results, it was aimed to investigate the haematological disturbances in liver cirrhotic patients.In the result there was a correlation between activated partial thromboplastin time, serum iron, ferritin, transferrin, haptoglobin and Child-Pugh classification. Besides there was no correlation between prothrombin time, factor 8 and 9, protein C and S, anti-thrombin 3, fibrinogen, fibrin degradation products, serum iron binding capacity, hemoglobin, leukocyte, mean corpuscular volume and Child-Pugh classification.There were significant difference, in terms of AST, ferritin, haptoglobulin, sex and presence of ascites between groups (p0.05. In the summary, we have found correlation between hemostatic abnormalities and disease activity and clinical prognosis in patients with liver cirrhosis which is important in the management of these patients. This is also important for identification of liver transplant candidiates earlier.

  15. [Cognitive abnormalities and cannabis use].

    Science.gov (United States)

    Solowij, Nadia; Pesa, Nicole

    2010-05-01

    Evidence that cannabis use impairs cognitive function in humans has been accumulating in recent decades. The purpose of this overview is to update knowledge in this area with new findings from the most recent literature. Literature searches were conducted using the Web of Science database up to February 2010. The terms searched were: "cannabi*" or "marijuana", and "cogniti*" or "memory" or "attention" or "executive function", and human studies were reviewed preferentially over the animal literature. Cannabis use impairs memory, attention, inhibitory control, executive functions and decision making, both during the period of acute intoxication and beyond, persisting for hours, days, weeks or more after the last use of cannabis. Pharmacological challenge studies in humans are elucidating the nature and neural substrates of cognitive changes associated with various cannabinoids. Long-term or heavy cannabis use appears to result in longer-lasting cognitive abnormalities and possibly structural brain alterations. Greater adverse cognitive effects are associated with cannabis use commencing in early adolescence. The endogenous cannabinoid system is involved in regulatory neural mechanisms that modulate processes underlying a range of cognitive functions that are impaired by cannabis. Deficits in human users most likely therefore reflect neuroadaptations and altered functioning of the endogenous cannabinoid system.

  18. Update on the nutrition situation.

    Science.gov (United States)

    Mason, J; Garcia, M

    1995-01-01

    The Update on the Nutrition Situation, 1994 was published in early 1995 by the United Nations Subcommittee on Nutrition. Thus, data available at the country level about estimates of the nutritional situation now provide trends of prevalences of underweight children in 35 countries for the 1990s. In Sub-Saharan Africa recent deterioration has occurred as a result of the general worsening of nutrition in Africa. However, in the Near East, North Africa, and South America the generally improving trends of the 1980s seem to be continuing with the likelihood of reaching the prevalences of the developed countries by the year 2000. A surveillance system in Bangladesh indicates improvement from 1990 to 1993; however, India data for 1991/92 indicate deterioration in 3 states and no significant change in 4, possibly connected the economic slowdown in the early 1990s. In many countries of southeast Asia, China, Middle America and the Caribbean, South America, the Near East and North Africa the improvement of rates could result in halving the prevalences of underweight children. The gross domestic product (GDP) is an important indicator of nutritional performance. During 1985-92 in Sub-Saharan Africa GDP declined by 0.8% and consequently the nutritional situation also deteriorated. In other areas of the world the GDP growth rates improved after 1990 and the underweight trends in the early 1990s were generally similar to those of the late 1980s. The nutritional improvement outside Sub-Saharan Africa and possibly India continued in the early 1990s. Rapid economic growth was associated with improving nutrition in Thailand and Vietnam in the 1980s and also to a smaller extent for Indonesia and China. Faster than average improvement is plausible for Jamaica, Sri Lanka, and Zimbabwe. Deteriorating cases are Ethiopia, Madagascar, and Rwanda. Economic growth, health, education, and community-based nutrition programs all contribute to improving nutrition.

    The complexity of the work situation during abnormal situations is a major topic in a discussion of safety aspects of Nuclear Power plants. An understanding of complexity and its impact on operator performance in abnormal situations is important. One way to enhance understanding is to look at the dimensions that constitute complexity for NPP operators, and how those dimensions can be measured. A further step is to study how dimensions of complexity of the event are related to performance of operators. One aspect of complexity is the operator 's subjective experience of given difficulties of the event. Another related aspect of complexity is subject matter experts ratings of the complexity of the event. A definition and a measure of this part of complexity are being investigated at the OECD Halden Reactor Project in Norway. This paper focus on the results from a study of simulated scenarios carried out in the Halden Man-Machine Laboratory, which is a full scope PWR simulator. Six crews of two licensed operators each performed in 16 scenarios (simulated events). Before the experiment subject matter experts rated the complexity of the scenarios, using a Complexity Profiling Questionnaire. The Complexity Profiling Questionnaire contains eight previously identified dimensions associated with complexity. After completing the scenarios the operators received a questionnaire containing 39 questions about perceived complexity. This questionnaire was used for development of a measure of subjective complexity. The results from the study indicated that Process experts' rating of scenario complexity, using the Complexity Profiling Questionnaire, were able to predict crew performance quite well. The results further indicated that a measure of subjective complexity could be developed that was related to crew performance. Subjective complexity was found to be related to subjective work load.

  1. Thoughts on the Postpartum Situation

    Full Text Available The event of childbirth carries with it a dominant narrative: that a pregnant woman happily gives birth to a baby. This appears to be quite a simple formulation—as if a natural fact, as if plain and common sense. Yet, the complexities masked by the mythological and whitewashed quality of this narrative, as I have already argued recently in The Pregnancy ≠ Childbearing Project: A Phenomenology of Miscarriage (Feb 2017, harms and even kills women. In this paper, I expand on the problem of what I term “dismemberment after birth” as it operates invisibly in the “postpartum situation.” The dominant narrative, combined with a pervasive cultural misogynoir— manifesting specifically as an antagonism toward black women and women of color—as medicalized and ableist establishment of care, renders women without resource if they cannot maintain the desires and embodiments required of a contented and successful maternity. The naturalized assumptions about the narrative move from the birth event to “having a baby” are disrupted here with hope of opening up an opportunity to validate and diversify the more non-linear narratives. As an afterthought to these disruptions, I offer an additional challenge to anti-natalist thinking in its limited insight into the postpartum situation.

    The layperson's qualification to provide early care in emergency situations and basic life support (BLS) is fundamental to save lives and prevent sequels. The objective was to identify the level of knowledge of lay people about approaching an emergency victim. Structured interviews in non-technical language were used with a 385-subject sample, average age 35.4 (+/- 14.55) years, with more than 50% having a high school or university education. Over 55% of these observed situations with loss of consciousness, but only 31% called for specialized help. 34% underwent a first-aid course, but only 13% feel prepared. The most often cited place of learning was the driving school (DS), 35.9%. Other training places were higher when compared to the DS (p = 0.048). Almost 17% do not know how to recognize the presence of vital signs. Almost 31% do not know the telephone number of the emergency service. Laypersons have incomplete or incorrect knowledge about care for unconscious victims.

    Full Text Available The study on diagnosis method of concrete crack behavior abnormality has always been a hot spot and difficulty in the safety monitoring field of hydraulic structure. Based on the performance of concrete dam crack behavior abnormality in parametric statistical model and nonparametric statistical model, the internal relation between concrete dam crack behavior abnormality and statistical change point theory is deeply analyzed from the model structure instability of parametric statistical model and change of sequence distribution law of nonparametric statistical model. On this basis, through the reduction of change point problem, the establishment of basic nonparametric change point model, and asymptotic analysis on test method of basic change point problem, the nonparametric change point diagnosis method of concrete dam crack behavior abnormality is created in consideration of the situation that in practice concrete dam crack behavior may have more abnormality points. And the nonparametric change point diagnosis method of concrete dam crack behavior abnormality is used in the actual project, demonstrating the effectiveness and scientific reasonableness of the method established. Meanwhile, the nonparametric change point diagnosis method of concrete dam crack behavior abnormality has a complete theoretical basis and strong practicality with a broad application prospect in actual project.

  4. Effect of Time-Dependent Pinning Pressure on Abnormal Grain Growth: Phase Field Simulation

    2018-05-01

    The effect of the time-dependent pinning pressure of precipitates on abnormal grain growth has been investigated by multiphase field simulation with a simple precipitation model. The application of constant pinning pressure is problematic because it always induces abnormal grain growth or no grain growth, which is not reasonable considering the real situation. To produce time-dependent pinning pressure, both precipitation kinetics and precipitate coarsening kinetics have been considered with two rates: slow and fast. The results show that abnormal grain growth is suppressed at the slow precipitation rate. At the slow precipitation rate, the overall grain growth caused by the low pinning pressure in the early stage indeed plays a role in preventing abnormal grain growth by reducing the mobility advantage of abnormal grains. In addition, the fast precipitate coarsening rate tends to more quickly transform abnormal grain growth into normal grain growth by inducing the active growth of grains adjacent to the abnormal grains in the early stage. Therefore, the present study demonstrates that the time dependence of the pinning pressure of precipitates is a critical factor that determines the grain growth mode.

  5. Constructing catalogue of temporal situations

    Full Text Available Constructing catalogue of temporal situations The paper is aiming to create a common basis for description, comparing, and analysis natural languages. As a subject of comparison we have chosen temporal structures of some languages. For such a choice there exists a perfect tool, describing basic temporal phenomena, namely an ordering of states and events in time, certainty and uncertainty, independency of histories of separate objects, necessity and possibility. This tool is supported by the Petri nets formalism, which seems to be well suited for expressing the above mentioned phenomena. Petri nets are built form three primitive notions: of states, of events that begin or end the states, and so-called flow relation indicating succession of states and events. This simple constituents give rise to many possibilities of representing temporal phenomena; it turns out that such representations are sufficient for many (clearly, not necessarily all temporal situations appearing in natural languages. In description formalisms used till now there is no possibility of expressing such reality phenomena as temporal dependencies in compound statement, or combination of temporality and modality. Moreover, using these formalisms one cannot distinguish between two different sources of uncertainty of the speaker while describing the reality: one, due to the lack of knowledge of the speaker what is going on in outside world, the second, due to objective impossibility of foreseen ways in which some conflict situations will be (or already have been resolved. Petri net formalism seems to be perfectly suited for such differentiations. There are two main description principles that encompassed this paper. First, that assigns meaning to names of grammatical structures in different languages may lead to misunderstanding. Two grammatical structures with apparently close names may describe different reality. Additionally, some grammatical terms used in one language may be

    Heart abnormality does not choose gender, age and races when it strikes. With no warning signs or symptoms, it can result to a sudden death of the patient. Generally, heart's irregular electrical activity is defined as heart abnormality. Via implementation of Multilayer Perceptron (MLP) network, this paper tries to develop a program that allows the detection of heart abnormality activity. Utilizing several training algorithms with Purelin activation function, an amount of heartbeat signals received through the electrocardiogram (ECG) will be employed to condition the MLP network.

  3. Mexican energy situation and perspectives

    1978-01-01

    The energy situation of Mexico is analyzed, including a projection to year 2000. An energy trade balance for 1975 is presented, including the energy invested in the imported and exported manufactured goods. Although Mexico is an oil exporting country, it is found that there was a net import of 32 million barrels of oil equivalent. The projection shows that by developing all alternative sources, hydrocarbons will supply 73% of all the primary energy at the end of the century. A 20,000 MW(e) nucleoelectric program would depress hydrocarbons percentage to 63%. It is concluded that there has been a lack of a coherent energy policy which would permit to elaborate adequate energy development programs. Some criteria are recommended for an energy policy: a) the oil export program should be reviewed; b) The country should encourage the generation of its own technology; c) The energy demand growth-rate should be maintained high enough until an acceptable level of per-capita consumption is reached; d) The internal prices of energy should be reviewed to modify the consumption scheme and e) The primary energy sources should be diversified as possible; with special emphasis on nuclear energy which is the only one important alternative at short time.

    Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

    During routine contamination checks we encountered an abnormal high level of Alpha and Beta emitting radioisotopes on working gloves of employees of the gardening department. It came out that the source was due to ''contamination'' levels on steering wheels of some gardening machines. In order to ensure that no real contamination of these workers was involved , a series of checks was started to identity the source of the abnormal levels found during monitoring

    Visual fields were examined with a tangent screen in 54 patients with multiple sclerosis (MS) or optic neuritis (ON). Visual fields were abnormal in all patients with definite MS, 94% with probable MS and 81% with possible MS. Three-quarters of the MS patients with no history of visual symptoms had abnormal fields. The commonest defect found was an arcuate scotoma. As a diagnostic test of visual pathway involvement in MS, tangent screen examination compares favourably with more sophisticated ...

    The aim of this study was to investigate and describe the range of white matter abnormalities in children with tuberous sclerosis complex by means of MR imaging. Material and Methods: A retrospective cross-sectional study was performed on the basis of MR imaging findings in 20 cases of tuberous sclerosis complex in children aged 17 years or younger. Results: White matter abnormalities were present in 19/20 (95%) cases of tuberous sclerosis complex. These were most frequently (19/20 cases) found in relation to cortical tubers in the supratentorial compartment. White matter abnormalities related to tubers were found in the cerebellum in 3/20 (15%) cases. White matter abnormalities described as radial migration lines were found in relation to 5 tubers in 3 (15%) children. In 4/20 (20%) cases, white matter abnormalities were found that were not related to cortical tubers. These areas had the appearance of white matter cysts in 3 cases and infarction in the fourth. In the latter case there was a definable event in the clinical history, supporting the diagnosis of stroke. Conclusion: A range of white matter abnormalities were found by MR imaging in tuberous sclerosis complex, the commonest being gliosis and hypomyelination related to cortical tubers. Radial migration lines were seen infrequently in relation to cortical tubers and these are thought to represent heterotopic glia and neurons along the expected path of cortical migration. (orig.)

    To evaluate the effectiveness of the hysteroscopic polypectomy in terms of the decrease of the abnormal uterine bleeding. A cross-sectional and analytical study was done with patients to whom a hysteroscopic polypectomy was done for treating the abnormal uterine bleeding, between January 2009 and December 2013. The response to the treatment was evaluated via a survey given to the patients about the behavior of the abnormal uterine bleeding after the procedure and about overall satisfaction. The results were obtained after a hysteroscopic polypectomy done to 128 patients and were as follows. The average time from the polypectomy applied until the survey was 30.5 months, with a standard deviation of 18 months. 67.2% of the patients reported decreased abnormal uterine bleeding and the 32.8% reported a persistence of symptoms. On average 82.8% of the. patients were satisfied with the treatment. Bivariate and multivariate analysis showed no association between the variables studied and no improvement of abnormal uterine bleeding after surgery (polypectomy). There were no complications. Hysteroscopic polypectomy is a safe surgical treatment, which decreases on two of three patients the abnormal uterine bleeding in the presence of endometrial polyps, with an acceptable level of satisfaction.

    Two efferent feedback pathways to the auditory periphery may play a role in monitoring self-vocalization: the middle-ear acoustic reflex (MEAR) and the medial olivocochlear bundle (MOCB) reflex. Since most studies regarding the role of auditory efferent activity during self-vocalization were conducted in animals, human data are scarce. The working premise of the current study was that selective mutism (SM), a rare psychiatric disorder characterized by consistent failure to speak in specific social situations despite the ability to speak normally in other situations, may serve as a human model for studying the potential involvement of auditory efferent activity during self-vocalization. For this purpose, auditory efferent function was assessed in a group of 31 children with SM and compared to that of a group of 31 normally developing control children (mean age 8.9 and 8.8 years, respectively). All children exhibited normal hearing thresholds and type A tympanograms. MEAR and MOCB functions were evaluated by means of acoustic reflex thresholds and decay functions and the suppression of transient-evoked otoacoustic emissions, respectively. Auditory afferent function was tested by means of auditory brainstem responses (ABR). Results indicated a significantly higher proportion of children with abnormal MEAR and MOCB function in the SM group (58.6 and 38%, respectively) compared to controls (9.7 and 8%, respectively). The prevalence of abnormal MEAR and/or MOCB function was significantly higher in the SM group (71%) compared to controls (16%). Intact afferent function manifested in normal absolute and interpeak latencies of ABR components in all children. The finding of aberrant efferent auditory function in a large proportion of children with SM provides further support for the notion that MEAR and MOCB may play a significant role in the process of self-vocalization. © 2013 S.

    Triangular fibrocartilage complex abnormalities seem to be more common with age, but the degree to which this is so, and the degree to which the presence of an abnormality is associated with symptoms, are topics of controversy. We wished to perform a systematic review to determine the prevalence of triangular fibrocartilage complex abnormalities, and to determine if the prevalence of abnormalities are greater with increasing age. In addition, we stratified age groups based on symptoms. We searched MEDLINE, EMBASE, and the Cochrane Library through August 15, 2013. Studies that reported triangular fibrocartilage complex abnormalities by age were included. Fifteen studies including 977 wrists met our criteria and reported a total of 368 (38%) triangular fibrocartilage complex abnormalities. Eight studies included symptomatic patients; the remainder studied cadavers (six studies) or asymptomatic volunteers (one study). Patients were divided into four age groups (fibrocartilage complex abnormalities increased with age, from 27% (80/301) in patients younger than 30 years to 49% (130/265) in patients 70 years and older (p fibrocartilage complex prevalence abnormality increased from 15% (24/159) to 49% (129/263) in the same age groups (p fibrocartilage complex abnormalities are common in symptomatic and asymptomatic wrists, and they are increasingly common with age. As in all situations where abnormalities are so common that they may be incidental, we need (1) a reliable and accurate method for determining whether these abnormalities are the cause of symptoms; and (2) evidence that treatment of these abnormalities improves symptoms better than placebo.

  4. Normal or abnormal? 'Normative uncertainty' in psychiatric practice.

    The 'multicultural clinical interaction' presents itself as a dilemma for the mental health practitioner. Literature describes two problematic areas where this issues emerges--how to make an adequate distinction between religious rituals and the rituals that may be symptomatic of 'obsessive compulsive disorder' (OCD), and how to differentiate 'normative' religious or spiritual beliefs, behaviours, and experiences from 'psychotic' illnesses. When it comes to understanding service user's 'idioms of distress', beliefs about how culture influences behaviour can create considerable confusion and 'normative uncertainty' for mental health practitioners. In the absence of clear diagnostic and assessment criteria on distinguishing between 'culture' and 'psychopathology', practitioners have had to rely on their own intuition and seek out possible 'strategies' or 'procedures' from a contradictory and cross-disciplinary evidence base. Decontextualisation of service users' experiences may result in the pathologisation of culturally 'normative' phenomenon, 'category fallacy' errors, and poor health care experiences and outcomes for service users.This paper situates this dilemma within a wider debate that has concerned both the biomedical and social sciences, namely, the unresolved question of 'normality' or 'abnormality'. Indeed, issues that arise from dilemmas surrounding the question of 'culture' or 'psychopathology' are intimately tied to wider cultural ideas about what is considered 'normal'. The disciplines of psychiatry, psychology, and medical anthropology have struggled to establish workable criteria against which to judge behaviour as 'normal', 'abnormal', or 'pathological'. Three models for understanding mental 'abnormality' are evident in 'transcultural psychiatry' (what is now commonly known as 'cultural psychiatry'), and these models have corresponded closely to the interpretive models used by anthropologists attempting to make sense of the apparent diversity of

    This paper addresses the problem of learning situation models for providing context-aware services. Context for modeling human behavior in a smart environment is represented by a situation model describing environment, users, and their activities. A framework for acquiring and evolving different layers of a situation model in a smart environment is proposed. Different learning methods are presented as part of this framework: role detection per entity, unsupervised extraction of situations from multimodal data, supervised learning of situation representations, and evolution of a predefined situation model with feedback. The situation model serves as frame and support for the different methods, permitting to stay in an intuitive declarative framework. The proposed methods have been integrated into a whole system for smart home environment. The implementation is detailed, and two evaluations are conducted in the smart home environment. The obtained results validate the proposed approach.

    There is an increasing recognition by commercial and civil space operators of the need for space situational awareness (SSA) data to support ongoing conjunction analysis, maneuver planning, and radio frequency interference mitigation as part of daily operations. While some SSA data is available from the Joint Space Operations Center via the Space Track web site, access to raw observations and photometric data is limited due to national security considerations. These data, however, are of significant value in calibrating intra- and inter-operator orbit determination results, determining inter-system biases, and assessing operating profiles in the geostationary orbit. This paper details an ongoing collaborative effort to collect and process optical observations and photometric data using a network of low-cost telescope installations and shows how these data are being used to support ongoing operations in the Space Data Center. This presentation will demonstrate how by leveraging advance photometric processing algorithms developed for Missile Defense Agency and the Ballistic Missile Defense (BMD) mission ExoAnalytic and AGI have been able to provide actionable SSA for satellite operators from small telescopes in less than optimal viewing conditions. Space has become an increasingly cluttered environment requiring satellite operators to remain forever vigilant in order to prevent collisions to preserve their assets and prevent further cluttering the space environment. The Joint Space Operations Center (JSpOC), which tracks all objects in earth orbit, reports possible upcoming conjunctions to operators by providing Conjunction Summary Messages (CSMs). However due to large positional uncertainties in the forward predicted position of space objects at the time closest approach the volume of CSMs is excessive to the point that maneuvers in response to CSMs without additional screening is cost prohibitive. CSSI and the Space Data Association have been able to screen most

    Thermoluminescent phenomenon resulting from two kinds of complicated geological situation, Ordos Basin and Huainan deposits in Anhui Province, is studied by the means of thermoluminescence counting method. It is shown that: (1) there are no apparent abnormalities of natural TL detected from the rock samples selected in the first 1000 meter depth of the Earth, and these natural TL are accumulated through natural radiation effects; (2) the natural TL shows statistically obvious reducing trends for the rock samples selected under the 2000 meter depth, and even no detectable TL is found for those rocks selected at 4000 meter depth. (3) the natural TL peaks corresponding to high temperature generally shift to the direction of higher temperature for the quartz-related rock samples, and several thermal events which occurred during the geological times might be responsible for this case

    Highlights: • We proposed quantitative situation awareness (SA) evaluation technique. • We developed a computer based SA evaluation tool for NPPs training environment. • We introduced three rules and components to express more human-like results. • We conducted three sets of training with real plant operators. • Results showed that the tool could reasonably represent operator’s SA. - Abstract: Operator performance measures are used for multiple purposes, such as control room design, human system interface (HSI) evaluation, training, and so on. Performance measures are often focused on results; however, especially for a training purpose – at least in a nuclear industry, more detailed descriptions about processes are required. Situation awareness (SA) measurements have directly/indirectly played as a complimentary measure and provided descriptive insights on how to improve performance of operators for the next training. Unfortunately, most of the well-developed SA measurement techniques, such as Situation Awareness Global Assessment Technique (SAGAT) need an expert opinion which sometimes troubles easy spread of measurement’s application or usage. A quantitative SA measurement tool named Computational Representation of Situation Awareness with Graphical Expressions (CoRSAGE) is introduced to resolve some of these concerns. CoRSAGE is based on production rules to represent a human operator’s cognitive process of problem solving, and Bayesian inference to quantify it. Petri Net concept is also used for graphical expressions of SA flow. Three components – inference transition, volatile/non-volatile memory tokens – were newly developed to achieve required functions. Training data of a Loss of Coolant Accident (LOCA) scenario for an emergency condition and an earthquake scenario for an abnormal condition by real plant operators were used to validate the tool. The validation result showed that CoRSAGE performed a reasonable match to other performance

    Secondary amenorrhea is a condition in which there is cessation of menses after at least one menstruation. It is a symptom of different diseases, such as hormonal disturbances which range from pituitary to ovarian origin, as well as chromosomal abnormalities. Knowledge of the distinct cause of secondary amenorrhea is of tremendous benefit for the management and monitoring of patients. In this study, we determine the chromosomal abnormalities in patients with secondary amenorrhea in Southwest Iran. We selected 94 patients with secondary amenorrhea who referred to our Cytogenetic Ward from 2004 until 2009. For karyotyping, peripheral blood lymphocyte cultures were set up by conventional technique. In this study, 5.3% (n=5) of patients with secondary amenorrhea presented with chromosomal abnormalities, of which all contained an X element. The chromosomal abnormalities were: i) 45, X (n=1); ii) 47, XXX (n=1); iii) 45, X [13]/ 45, Xi(X)q[17] (n=1);  iv) 45, X[12]/46,X,+mar[12] (n=1); and v) 46,X,del(Xq)(q23q28) (n=1). Our study revealed that some causes of secondary amenorrhea could be due to chromosomal abnormalities. Therefore, cytogenetic studies should be important tests in the evaluation of patients with secondary amenorrhea.

    With so many terms available to define the same thing, it would seem nearly irresponsible to introduce yet another term (complex situation) to describe a phenomenological state of such as a system. However, a complex situation infers both a broader meaning and imposes a different perspective. Complex in this context is dependent on understanding and reality rather than observer and knowledge.   Situation imposes a gestalt that cannot be characterized within a singular perspective that relegates paradox to a superior/subordinate hierarchy. This also infers that complex situation has no monotonic definition or each definition is by default incomplete. Therefore the perennial derivations for systems such as complex systems, system of systems, federation of systems is no longer a sufficient descriptor for complex situation.  Ergo system and its genealogy lack the constitution to define complex situations. The books' intent is to explore this pathology through a series of papers written by authors that work in ...

    Cardiac abnormality often occurs regardless of gender, age and races but depends on the lifestyle. This problem sometimes does not show any symptoms and usually detected once it already critical which lead to a sudden death to the patient. Basically, cardiac abnormality is the irregular electrical signal that generate by the pacemaker of the heart. This paper attempts to develop a program that can detect cardiac abnormality activity through implementation of Hybrid Multilayer Perceptron (HMLP) network. A certain amount of data of the heartbeat signals from the electrocardiogram (ECG) will be used in this project to train the MLP and HMLP network by using Modified Recursive Prediction Error (MRPE) algorithm and to test the network performance.

    Dysaesthesiae of the scalp and neurological abnormality after mobile phone use have been reported previously, but the roles of the phone per se or the radiations in causing these findings have been questioned. We report finding a neurological abnormality in a patient after accidental exposure of the left side of the face to mobile phone radiation [code division multiple access (CDMA)] from a down-powered mobile phone base station antenna. He had headaches, unilateral left blurred vision and pupil constriction, unilateral altered sensation on the forehead, and abnormalities of current perception thresholds on testing the left trigeminal ophthalmic nerve. His nerve function recovered during 6 months follow-up. His exposure was 0.015-0.06 mW/cm(2) over 1-2 h. The implications regarding health effects of radiofrequency radiation are discussed.

  16. Report on Congress on abnormal occurrences

    1991-06-01

    Section 208 of the energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event that the Nuclear Regulatory Commission determines to be significant from the standpoint of public health or safety and requires a quarterly report of such events to be made to Congress. This report covers the period from January 1 through March 31, 1991. The report discusses six abnormal occurrences, none of which involved a nuclear power plant. Five of the events occurred at NRC-licensed facilities: one involved a significant degradation of plant safety at a nuclear fuel cycle facility, one involved a medical diagnostic misadministration, and three involved medical therapy misadministrations. An Agreement State (Arizona) reported one abnormal occurrence that involved medical therapy misadministrations

    1990-01-01

    Computed tomography (CT) of the temporomandibular joint (TMJ) was compared with hypocycloidal tomography in 30 joints of 15 adults with rheumatic disease. CT included 1.5 mm thick axial scans (at 1.0 mm intervals) with reformatted oblique sagittal and oblique coronal sections. Multisection (at 2.0 mm intervals) tomography included oblique sagittal and occasionally, oblique coronal sections. CT demonstrated bone abnormalities in 21 and tomography in 20 joints, indicating high agreement between the imaging modalities regarding number of abnormal TMJs. Bone structures were, however, better visualized by multiplanar CT due to superior contrast and spatial resolution particularly in the most lateral and medial parts of the joint, indicating superiority of CT for depicting subtle bony TMJ abnormalities in patients with rheumatic disease.

    Several case reports have described adult respiratory distress syndrome (ARDS) secondary to tricyclic acid (TCA) overdose. During a 1-year period 83 patients requiring intubation secondary to drug overdose were evaluated. Abnormalities on chest radiographs occurred in 26 (50%) of the 54 patients with TCA overdose, compared to six (21%) of the 29 patients overdosed with other drugs. In addition, five (9%) of the patients with TCA overdose subsequently had radiographic and clinical abnormalities meeting the criteria for ARDS. Only one (3%) of the patients with non-TCA overdose subsequently had change suggesting ARDS. TCAs should be added to the list of drugs associated with ARDS, and TCA overdose should be considered a major risk factor in the development of radiographically evident abnormalities

    1986-01-01

    Purpose: To measure the collision energy easily and at high accuracy by applying impact shocks at known collision energy from a simulated acoustic wave generator and using the generated acoustic signal as reference data. Constitution: A plurality of acoustic detectors are attached to the surface of a nuclear reactor pressure vessel. These acoustic detectors are connected respectively to an abnormality diagnosis device for equipments. Then, when metal obstacles collide against the inner surface of the reactor pressure vessel, acoustic signals generated upon collision are detected by the acoustic detectors and acoustic information thus obtained from the acoustic detectors determines the colliding position of the metal obstacles by means of the abnormality diagnosis device and then the collision energy is measured. In this case, by applying impact shocks at known collision energy near the colliding position of metal obstacles determined by the abnormality diagnosis device, collision energy can be determined at a higher accuracy.

  1. Aircraft Abnormal Conditions Detection, Identification, and Evaluation Using Innate and Adaptive Immune Systems Interaction

    Science.gov (United States)

    Al Azzawi, Dia

    Abnormal flight conditions play a major role in aircraft accidents frequently causing loss of control. To ensure aircraft operation safety in all situations, intelligent system monitoring and adaptation must rely on accurately detecting the presence of abnormal conditions as soon as they take place, identifying their root cause(s), estimating their nature and severity, and predicting their impact on the flight envelope. Due to the complexity and multidimensionality of the aircraft system under abnormal conditions, these requirements are extremely difficult to satisfy using existing analytical and/or statistical approaches. Moreover, current methodologies have addressed only isolated classes of abnormal conditions and a reduced number of aircraft dynamic parameters within a limited region of the flight envelope. This research effort aims at developing an integrated and comprehensive framework for the aircraft abnormal conditions detection, identification, and evaluation based on the artificial immune systems paradigm, which has the capability to address the complexity and multidimensionality issues related to aircraft systems. Within the proposed framework, a novel algorithm was developed for the abnormal conditions detection problem and extended to the abnormal conditions identification and evaluation. The algorithm and its extensions were inspired from the functionality of the biological dendritic cells (an important part of the innate immune system) and their interaction with the different components of the adaptive immune system. Immunity-based methodologies for re-assessing the flight envelope at post-failure and predicting the impact of the abnormal conditions on the performance and handling qualities are also proposed and investigated in this study. The generality of the approach makes it applicable to any system. Data for artificial immune system development were collected from flight tests of a supersonic research aircraft within a motion-based flight

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

    Because abnormal psychology courses presuppose a focus on pathological human functioning, nonpathologizing interventions within these classes are particularly powerful and can reach survivors, bystanders, and perpetrators. Interventions are needed to improve the social response to trauma on college campuses. By applying psychodynamic and feminist multicultural theory, instructors can deliver nonpathologizing interventions about trauma and trauma response within these classes. We recommend class-based interventions with the following aims: (a) intentionally using nonpathologizing language, (b) normalizing trauma responses, (c) subjectively defining trauma, (d) challenging secondary victimization, and (e) questioning the delineation of abnormal and normal. The recommendations promote implications for instructor self-reflection, therapy interventions, and future research.

    PURPOSE OF REVIEW: The aim is to provide an overview of recent studies of structural brain abnormalities in migraine and to discuss the potential clinical significance of their findings. RECENT FINDINGS: Brain structure continues to be a topic of extensive research in migraine. Despite advances...... in neuroimaging techniques, it is not yet clear if migraine is associated with grey matter changes. Recent large population-based studies sustain the notion of increased prevalence of white matter abnormalities in migraine, and possibly of silent infarct-like lesions. The clinical relevance of this association...

    Recent imaging studies have associated Developmental dyscalculia (DD) to structural and functional alterations corresponding Parietal and the Prefrontal cortex (PFC). Since these areas were shown also to be involved in timing abilities, we hypothesized that time processing is abnormal in DD. We compared time processing abilities between 10 children with pure DD (8 years old) and 11 age-matched healthy children. Results show that the DD group underestimated duration of a sub-second scale when asked to perform a time comparison task. The timing abnormality observed in our DD participants is consistent with evidence of a shared fronto-parietal neural network for representing time and quantity.

    2017-02-01

    Rotation abnormalities may be asymptomatic or may be associated with obstruction caused by bands, midgut volvulus, or associated atresia or web. The most important goal of clinicians is to determine whether the patient has midgut volvulus with intestinal ischemia, in which case an emergency laparotomy should be done. If the patient is not acutely ill, the next goal is to determine whether the patient has a narrow-based small bowel mesentery. In general, the outcomes for children with a rotation abnormality are excellent, unless there has been midgut volvulus with significant intestinal ischemia. Copyright © 2016 Elsevier Inc.

    Lo Presti, Rosalia; Hopps, Eugenia; Caimi, Gregorio

    2014-05-01

    Blood rheology is impaired in hypertensive patients. The alteration involves blood and plasma viscosity, and the erythrocyte behaviour is often abnormal. The hemorheological pattern appears to be related to some pathophysiological mechanisms of hypertension and to organ damage, in particular left ventricular hypertrophy and myocardial ischemia. Abnormalities have been observed in erythrocyte membrane fluidity, explored by fluorescence spectroscopy and electron spin resonance. This may be relevant for red cell flow in microvessels and oxygen delivery to tissues. Although blood viscosity is not a direct target of antihypertensive therapy, the rheological properties of blood play a role in the pathophysiology of arterial hypertension and its vascular complications.

    2007-08-08

    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

    Full Text Available The personalization of learning is a major pedagogical challenge solicited by pedagogues and didacts. There are several projects about the production of personalizable learning situations such as Reload-LDE and Alfanet. These projects are interested in producing new standardized and personalizable learning situations. However, on the Web, an important number of learning situations exist. These situations are rich in information but don't consider all the characteristics of participants taking part in the learning, nor their technical environments. In this paper we suggest a help system that can transform an existing learning situation to another structure standardized and personalizable depending on the context of learning personalization that we have defined.

    Chromosome abnormalities in bone marrow cells were recognized in 6 cases which consisted of one case of chronic myelogenous leukemia, two cases of acute myelogenous leukemia, one case of sideroblastic anemia, and two cases of myelodysplasis. Frequency of stable type chromosome abnormalities in bone marrow cells was investigated in 45 atomic bomb survivors without hematologic disorders and 15 controls. It was 1.4% (15 cases) in the group exposed to atomic bomb within 1 km from the hypocenter, which was significantly higher as compared with 0.1% (15 cases) in the group exposed to atomic bomb over 2.5 km from the hypocenter and 0.2% in normal controls. Examination of chromosome was also made on 2 of 3 cases which were the seconds born of female with high chromosome abnormality, who was exposed to within 1 km from the hypocenter, and healthy male exposed 3 km from the hypocenter. These two cases showed chromosome of normal male type, and balanced translocation was not recognized. There was not a significant difference in chromosome abnormalities between the seconds of atomic bomb survivors and controls.

    Psychopathic offenders inevitably violate interpersonal norms and frequently resort to aggressive and criminal behaviour. The affective and cognitive deficits underlying these behaviours have been linked to abnormalities in functional interhemispheric connectivity. However, direct neurophysiological evidence for dysfunctional connectivity in psychopathic offenders is lacking. We used transcranial magnetic stimulation combined with electroencephalography to examine interhemispheric connectivity in the dorsolateral and motor cortex in a sample of psychopathic offenders and healthy controls. We also measured intracortical inhibition and facilitation over the left and right motor cortex to investigate the effects of local cortical processes on interhemispheric connectivity. We enrolled 17 psychopathic offenders and 14 controls in our study. Global abnormalities in right to left functional connectivity were observed in psychopathic offenders compared with controls. Furthermore, in contrast to controls, psychopathic offenders showed increased intracortical inhibition in the right, but not the left, hemisphere. The relatively small sample size limited the sensitivity to show that the abnormalities in interhemispheric connectivity were specifically related to the dorsolateral prefrontal cortex in psychopathic offenders. To our knowledge, this study provides the first neurophysiological evidence for abnormal interhemispheric connectivity in psychopathic offenders and may further our understanding of the disruptive antisocial behaviour of these offenders.

  15. Gastric emptying abnormal in duodenal ulcer

    Energy Technology Data Exchange (ETDEWEB)

    Holt, S.; Heading, R.C.; Taylor, T.V.; Forrest, J.A.; Tothill, P.

    1986-07-01

    To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.

    1993-01-01

    The device of the present invention rapidly detects a small amount of primary coolants leaked from a heat transfer pipes in a steam generator to estimate the scale of the rupture and forecast the transition of the amount of the leakage. That is, a gamma-ray spectrum and dose rate measuring system having a bypass line capable of decaying short half-time nuclides disposed to each of second main steam pipelines and primary coolant pipelines. Data obtained from the measuring systems are compared, to judge the presence of abnormal symptom due to leakage and further, radioactivity concentration in main steams is calculated based on the dose rate at each of the measuring points. Further, radioactivity concentration of the leakage from the secondary main steam pipelines is calculated by change with passage of time. With such procedures, when primary coolants are leaked to the secondary main steam pipelines, the dose rate of the measured system is changed, thereby enabling to recognize the state at the abnormal point. The transition of abnormalities can be forecast with reference to the dose rate by change with passage of time. Further, state of the abnormal point can be recognized based on the gamma-ray spectrum, which is inherent upon occurrence of fuel rupture. (T.S.)

    Full Text Available OBJECTIVE To determine the frequency and types of craniofacial abnormalities observed in patients with trisomy 18 or Edwards syndrome (ES. METHODS This descriptive and retrospective study of a case series included all patients diagnosed with ES in a Clinical Genetics Service of a reference hospital in Southern Brazil from 1975 to 2008. The results of the karyotypic analysis, along with clinical data, were collected from medical records. RESULTS: The sample consisted of 50 patients, of which 66% were female. The median age at first evaluation was 14 days. Regarding the karyotypes, full trisomy of chromosome 18 was the main alteration (90%. Mosaicism was observed in 10%. The main craniofacial abnormalities were: microretrognathia (76%, abnormalities of the ear helix/dysplastic ears (70%, prominent occiput (52%, posteriorly rotated (46% and low set ears (44%, and short palpebral fissures/blepharophimosis (46%. Other uncommon - but relevant - abnormalities included: microtia (18%, orofacial clefts (12%, preauricular tags (10%, facial palsy (4%, encephalocele (4%, absence of external auditory canal (2% and asymmetric face (2%. One patient had an initial suspicion of oculo-auriculo-vertebral spectrum (OAVS or Goldenhar syndrome. CONCLUSIONS: Despite the literature description of a characteristic clinical presentation for ES, craniofacial alterations may be variable among these patients. The OAVS findings in this sample are noteworthy. The association of ES with OAVS has been reported once in the literature.

    Chiari-like malformation (CM) and syringomyelia (SM) are widely reported in Cavalier King Charles Spaniels and Griffon Bruxellois dogs. Increasing evidence indicates that CM and SM also occur in other small and toy breed dogs, such as Chihuahuas. To describe the presence of SM and craniocervical junction (CCJ) abnormalities in Chihuahuas and to evaluate the possible association of CCJ abnormalities with SM. To describe CM/SM-related clinical signs and neurologic deficits and to investigate the association of CM/SM-related clinical signs with signalment, SM, or CCJ abnormalities. Fifty-three client-owned Chihuahuas. Prospective study. Questionnaire analyses and physical and neurologic examinations were obtained before magnetic resonance and computed tomography imaging. Images were evaluated for the presence of SM, CM, and atlantooccipital overlapping. Additionally, medullary kinking, dorsal spinal cord compression, and their sum indices were calculated. Scratching was the most common CM/SM-related clinical sign and decreased postural reaction the most common neurologic deficit in 73 and 87% of dogs, respectively. Chiari-like malformation and SM were present in 100 and 38% of dogs, respectively. Syringomyelia was associated with the presence of CM/SM-related clinical signs (P = 0.034), and medullary kinking and sum indices were higher in dogs with clinical signs (P = 0.016 and P = 0.007, respectively). Syringomyelia and CCJ abnormalities are prevalent in Chihuahuas. Syringomyelia was an important factor for the presence of CM/SM-related clinical signs, but many dogs suffered from similar clinical signs without being affected by SM, highlighting the clinical importance of CCJ abnormalities in Chihuahuas.

    To report a retrospective series of 84 cerebral developmental venous anomalies (DVAs), focusing on associated parenchymal abnormalities within the drainage territory of the DVA. DVAs were identified during routine diagnostic radiological work-up based on magnetic resonance imaging (MRI) (60 cases), computed tomography (CT) (62 cases) or both (36 cases). Regional parenchymal modifications within the drainage territory of the DVA, such as cortical or subcortical atrophy, white matter density or signal alterations, dystrophic calcifications, presence of haemorrhage or a cavernous-like vascular malformation (CVM), were noted. A stenosis of the collecting vein of the DVA was also sought for. Brain abnormalities within the drainage territory of a DVA were encountered in 65.4% of the cases. Locoregional brain atrophy occurred in 29.7% of the cases, followed by white matter lesions in 28.3% of MRI investigations and 19.3% of CT investigations, CVMs in 13.3% of MRI investigations and dystrophic calcification in 9.6% of CT investigations. An intracranial haemorrhage possibly related to a DVA occurred in 2.4% cases, and a stenosis on the collecting vein was documented in 13.1% of cases. Parenchymal abnormalities were identified for all DVA sizes. Brain parenchymal abnormalities were associated with DVAs in close to two thirds of the cases evaluated. These abnormalities are thought to occur secondarily, likely during post-natal life, as a result of chronic venous hypertension. Outflow obstruction, progressive thickening of the walls of the DVA and their morphological organization into a venous convergence zone are thought to contribute to the development of venous hypertension in DVA.

    Health Care professionals working in disaster situations have to face urgent choices which diverge from their normal deontological ethos and are more utilitarian. Such is the triage system used to choose whom to treat. Instead of entering a crisis these professionals should be thought that ethics is not harmonizable to all situations and that there are situations in which saving as many lives as possible mean sacrificing others. This calls for defining a perimeter zone in which such choices occur, and a time frame (a space-time niche) in which it ought to be considered ethical and legitimate to use such value laden choices.

    To assess the auditory and vestibular function in patients with diabetes. We studied and followed for three years, 10 patients (6 females) of 20.6 years of age (SD 5.5 years), with insulindependent diabetes mellitus of 9.5 years (SD 3.7 years). The patients were selected for having peripheral neuropathy without prolipherative retinopathy and otologic disease or individual factors which could cause neurootologic symptoms. Their glomerular filtration rate and renal plasma flow were 150 mL/min (SD 50) and 543 mL/min (SD 113). Initially all patients had normal audiologic responses, including auditory brainstem responses, but had abnormally and simetrically diminished horizontal vestibulo-ocular responses. A year later one patient had vertigo and asymmetric vestibulo-ocular responses. In the third year, another patient showed similar abnormalities and a third one showed sensorineural hearing loss. Our results suggest that patients with insulindependent diabetes mellitus may suffer neuro-otological deterioration.

    Epileptic discharges are not considered a part of the clinical picture of selective mutism, and electroencephalography is generally not recommended in its work-up. This report describes 6 children with selective mutism who were found to have a history of epilepsy and abnormal interictal or subclinical electroencephalography recordings. Two of them had benign epilepsy of childhood with centro-temporal spikes. The mutism was not related in time to the presence of active seizures. While seizures could be controlled in all children by medications, the mutism resolved only in 1. Although the discharges could be coincidental, they might represent a co-morbidity of selective mutism or even play a role in its pathogenesis. Selective mutism should be listed among the psychiatric disorders that may be associated with electroencephalographic abnormalities. It can probably be regarded as a symptom of a more complicated organic brain disorder.

    1985-01-01

    The authors studied gastric emptying (GE) in patients with peripheral manifestations of progressive systemic sclerosis (PSS) using a radionuclide method. 18 patients underwent esophageal manometry and a GE study using chicken liver labeled in vivo with Tc-99m sulfur colloid as a marker of solid emptying. GE was also measured in 13 normal volunteers. 4 PSS patients with normal esophageal motility also had normal GE. The GE of 14 PSS patients with abnormal esophageal motility was significantly (p < 0.05) delayed; with 67.4% retention of isotope after 2 hours compared to 49.8 in normals. The authors conclude that GE of solids is slow in approximately 2/3 of PSS patients with abnormal esophageal motility but is normal if the esophagus is uninvolved; Delayed GE may contribute to the severity of gastroesophageal reflux in PSS patients and the degree of dysphasgia; and Metoclopramide accelerates GE in PSS patients and should have a valuable therapeutic role

    Over a 3.5 year period of time, 345 patients hospitalized for psychiatric problems were evaluated cytogenetically. The patient population included 76% males and 94% children with a mean age of 12 years. The criteria for testing was an undiagnosed etiology for mental retardation and/or autism. Cytogenetic studies identified 11, or 3%, with abnormal karyotypes, including 4 fragile X positive individuals (2 males, 2 females), and 8 with chromosomal aneuploidy, rearrangements, or deletions. While individuals with chromosomal abnormalities do not demonstrate specific behavioral, psychiatric, or developmental problems relative to other psychiatric patients, our results demonstrate the need for an increased awareness to order chromosomal analysis and fragile X testing in those individuals who have combinations of behavioral/psychiatric, learning, communication, or cognitive disturbance. 5 refs., 1 fig., 2 tabs.

    2015-08-01

    Full Text Available In order to reflect the situation of network security assessment performance fully and accurately, a new network security situation awareness model based on information fusion was proposed. Network security situation is the result of fusion three aspects evaluation. In terms of attack, to improve the accuracy of evaluation, a situation assessment method of DDoS attack based on the information of data packet was proposed. In terms of vulnerability, a improved Common Vulnerability Scoring System (CVSS was raised and maked the assessment more comprehensive. In terms of node weights, the method of calculating the combined weights and optimizing the result by Sequence Quadratic Program (SQP algorithm which reduced the uncertainty of fusion was raised. To verify the validity and necessity of the method, a testing platform was built and used to test through evaluating 2000 DAPRA data sets. Experiments show that the method can improve the accuracy of evaluation results.

    Does situational leadership style impact workers with disabilities? Situational leadership as a model and style of organizational management is defined. With a concentration on workers with disabilities, employer and employee perceptions of the workplace environment are analyzed as a contributing factor to the choice of leadership styles. Leadership style and its potential impact on workers with disabilities are included. Advantages of situational leadership style as an organizational model for managers that matches the intricate needs of workers with disabilities are argued. Methods for increasing awareness of the needs of persons with disabilities in the workplace and improving leadership models are discussed. Implications and potential outcomes for workers with disabilities based on the use of situational leadership by managers are discussed.

  20. Diagnostic orientation in control of disturbance situations

    Hukki, K.; Norros, L.

    1993-01-01

    The object of the study is diagnostic judgement in the control of dynamic processes. The starting point was the known difficulty process operators have in utilizing knowledge of process dynamics in disturbance situations that require both diagnostic and prognostic actions. A model of the diagnostic judgement process as a construction of coherent interpretation of the situation is outlined, and comprehensive data from simulated disturbance handling by 6 crews of a PWR type nuclear power plant was analysed. The phase of analysis included evaluation of the adequacy of task performance, utilization of available process information, and evaluation of the interpretation of disturbance situations. The results suggest that a functional orientation towards task performance allows a more coherent and comprehensive interpretation of the situation and more adequate task performance. Coherence of interpretation seems to be reflected in a higher subjective certainty compared with crews with an incoherent interpretation. (author). 15 refs, 2 figs, 2 tabs

    This report presents methods for continuous measures for Situation Awareness and Workload. The objective has been to identify, develop and test the new measures, and compare them to instruments that require interruptions of scenarios. The new measures are: (1) the Visual Indicator of Situation Awareness (VISA); where Situation Awareness is scored from predefined areas of visual interest critical for solving scenarios. Visual monitoring of areas was recorded by eye-movement tracking. (2) Workload scores reflected by Extended Dwell Time (EDT) and the operator Activity Level. EDT was calculated from eye-movement data files, and the activity level was estimated from simulator logs. Using experimental data from the 1996 CASH NRC Alarm study and the 1997 Human Error Analysis Project/ Human-Centred Automation study, the new measurement techniques have been tested and evaluated on a preliminary basis. The results showed promising relationships between the new continuous measures of situation awareness and workload, and established instruments based upon scenario interruptions. (author)

    CT is capable of demonstrating various venous changes. However, little have been described on this subject in the literature. Examples of various venous abnormalities such as obstructed jugular vein, superior and inferior vena cava (IVC), tumor invasion of IVC and renal vein and venous changes in portal hypertension were presented. It was stressed that noninvasive CT is a good tool in diagnosis of some of venous changes and may be able to eliminate angiography in such cases.

    Chronic heart failure (HF) is associated with morphologic abnormalities of cardiac mitochondria including hyperplasia, reduced organelle size and compromised structural integrity. In this study, we examined whether functional abnormalities of mitochondrial respiration are also present in myocardium of patients with advanced HF. Mitochondrial respiration was examined using a Clark electrode in an oxygraph cell containing saponin-skinned muscle bundles obtained from myocardium of failed explanted human hearts due to ischemic (ICM, n=9) or idiopathic dilated (IDC, n=9) cardiomyopathy. Myocardial specimens from five normal donor hearts served as controls (CON). Basal respiratory rate, respiratory rate after addition of the substrates glutamate and malate (V(SUB)), state 3 respiration (after addition of ADP, V(ADP)) and respiration after the addition of atractyloside (V(AT)) were measured in scar-free muscle bundles obtained from the subendocardial (ENDO) and subepicardial (EPI) thirds of the left ventricular (LV) free wall, interventricular septum and right ventricular (RV) free wall. There were no differences in basal and substrate-supported respiration between CON and HF regardless of etiology. V(ADP)was significantly depressed both in ICM and IDC compared to CON in all the regions studied. The respiratory control ratio, V(ADP)/V(AT), was also significantly decreased in HF compared to CON. In both ICM and IDC, V(ADP)was significantly lower in ENDO compared to EPI. The results indicate that mitochondrial respiration is abnormal in the failing human heart. The findings support the concept of low myocardial energy production in HF via oxidative phosphorylation, an abnormality with a potentially impact on global cardiac performance.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted. PMID:24868489

  9. The handicap of abnormal colour vision.

    Cole, Barry L

    2004-07-01

    All people with abnormal colour vision, except for a few mildly affected deuteranomals, report that they experience problems with colour in everyday life and at work. Contemporary society presents them with increasing problems because colour is now so widely used in printed materials and in computer displays. Equal opportunity law gives them protection against unfair discrimination in employment, so a decision to exclude a person from employment on the grounds of abnormal colour vision must now be well supported by good evidence and sound argument. This paper reviews the investigations that have contributed to understanding the nature and consequences of the problems they have. All those with abnormal colour vision are at a disadvantage with comparative colour tasks that involve precise matching of colours or discrimination of fine colour differences either because of their loss of colour discrimination or anomalous perception of metamers. The majority have problems when colour is used to code information, in man-made colour codes and in naturally occurring colour codes that signal ripeness of fruit, freshness of meat or illness. They can be denied the benefit of colour to mark out objects and organise complex visual displays. They may be unreliable when a colour name is used as an identifier. They are slower and less successful in search when colour is an attribute of the target object or is used to organise the visual display. Because those with the more severe forms of abnormal colour vision perceive a very limited gamut of colours, they are at a disadvantage in the pursuit and appreciation of those forms of art that use colour.

    To determine the prevalence of laryngopharyngeal (LP) abnormalities in hospitalized patients with dysphagia referred for flexible endoscopic evaluation of swallowing (FEES). Retrospective, blinded review by two otolaryngologists of 100 consecutive FEES studies performed and video-recorded by a speech-language pathologist (SLP). Two otolaryngologists reviewed videos of 100 consecutive FEES studies on hospitalized patients with dysphagia for the presence of abnormal LP findings. Sixty-one male and 38 female patients comprised the hospital dysphagia cohort. The mean age was 62. One subject could not be evaluated because of the severity of the retained secretions, leaving 99 subjects in the cohort. Seventy-six percent had been previously intubated, with a mean intubation duration of 13 days. The overall prevalence of abnormal LP findings was 79%. Forty-five percent of the patients presented with two or more findings, which included arytenoid edema (33%), granuloma (31%), vocal fold paresis (24%), mucosal lesions (17%), vocal fold bowing (14%), diffuse edema (11%), airway stenosis (3%), and ulcer (6%). There was a significant difference in LP findings between those individuals who had or had not been intubated. Hospitalized patients with dysphagia are at high risk for LP abnormalities, particularly if they have been intubated, and may benefit from either 1) an initial joint examination by the SLP and otolaryngologist or 2) an otolaryngologist's review of the recorded examination conducted by the SLP. Such otolaryngology involvement could identify airway stenosis patients at an earlier stage, initiate granuloma treatment sooner, enable earlier biopsy of unexpected lesions, and allow follow-up of mucosal and neuromuscular findings that do not respond to medical management.

    Full Text Available Abstract Background Prediabetes (PreDM in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV. Hypothesis Systemic inflammation and glycemia influence circadian blood pressure variability. Methods Dahl salt-sensitive (S rats (n = 19 after weaning were fed either an American (AD or a standard (SD diet. The AD (high-glycemic-index, high-fat simulated customary human diet, provided daily overabundant calories which over time lead to body weight gain. The SD (low-glycemic-index, low-fat mirrored desirable balanced human diet for maintaining body weight. Body weight and serum concentrations for fasting glucose (FG, adipokines (leptin and adiponectin, and proinflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1 and tumor necrosis factor-α (TNF-α] were measured. Rats were surgically implanted with C40 transmitters and blood pressure (BP-both systolic; SBP and diastolic; DBP and heart rate (HR were recorded by telemetry every 5 minutes during both sleep (day and active (night periods. Pulse pressure (PP was calculated (PP = SBP-DBP. Results [mean(SEM]: The AD fed group displayed significant increase in body weight (after 90 days; p Conclusion These data validate our stated hypothesis that systemic inflammation and glycemia influence circadian blood pressure variability. This study, for the first time, demonstrates a cause and effect relationship between caloric excess, enhanced systemic inflammation, dysglycemia, loss of blood pressure control and abnormal CBPV. Our results provide the fundamental basis for examining the relationship between dysglycemia and perturbation of the underlying mechanisms (adipose tissue dysfunction induced local and systemic inflammation, insulin resistance and alteration of adipose tissue precursors for the renin-aldosterone-angiotensin system which generate abnormal CBPV.

  13. Binocular combination in abnormal binocular vision.

    Ding, Jian; Klein, Stanley A; Levi, Dennis M

    2013-02-08

    We investigated suprathreshold binocular combination in humans with abnormal binocular visual experience early in life. In the first experiment we presented the two eyes with equal but opposite phase shifted sine waves and measured the perceived phase of the cyclopean sine wave. Normal observers have balanced vision between the two eyes when the two eyes' images have equal contrast (i.e., both eyes contribute equally to the perceived image and perceived phase = 0°). However, in observers with strabismus and/or amblyopia, balanced vision requires a higher contrast image in the nondominant eye (NDE) than the dominant eye (DE). This asymmetry between the two eyes is larger than predicted from the contrast sensitivities or monocular perceived contrast of the two eyes and is dependent on contrast and spatial frequency: more asymmetric with higher contrast and/or spatial frequency. Our results also revealed a surprising NDE-to-DE enhancement in some of our abnormal observers. This enhancement is not evident in normal vision because it is normally masked by interocular suppression. However, in these abnormal observers the NDE-to-DE suppression was weak or absent. In the second experiment, we used the identical stimuli to measure the perceived contrast of a cyclopean grating by matching the binocular combined contrast to a standard contrast presented to the DE. These measures provide strong constraints for model fitting. We found asymmetric interocular interactions in binocular contrast perception, which was dependent on both contrast and spatial frequency in the same way as in phase perception. By introducing asymmetric parameters to the modified Ding-Sperling model including interocular contrast gain enhancement, we succeeded in accounting for both binocular combined phase and contrast simultaneously. Adding binocular contrast gain control to the modified Ding-Sperling model enabled us to predict the results of dichoptic and binocular contrast discrimination experiments

    Full Text Available The Philadelphia (Ph chromosome and/or Breakpoint cluster region-Abelson leukemia virus oncogene transcript are unique markers for chronic myeloid leukemia (CML. However, CML demonstrates heterogeneous presentations and outcomes. We analyzed the cytogenetic and molecular results of CML patients to evaluate their correlation with clinical presentations and outcome. A total of 84 newly diagnosed CML patients were enrolled in the study. Patients were treated according to disease status. Bone marrow samples were obtained to perform cytogenetic and molecular studies. Clinical presentations, treatment courses, and survival were reviewed retrospectively. Among 84 patients, 72 had chronic phase and 12 had accelerated phase CML. Cytogenetic study showed 69 (82.1% with the classic Ph chromosome, 6 (7.2% with a variant Ph chromosome, and 9 (10.7% with additional chromosome abnormalities. Fifty-four (64.3% cases harbored b3a2 transcripts, 29 (34.5% had b2a2 transcript, and 1 had e19a2 transcript. There was no difference in clinical presentations between different cytogenetic and molecular groups; however, additional chromosome abnormalities were significantly associated with the accelerated phase. Imatinib therapy was an effective treatment, as measured by cytogenetic response, when administered as first- and second-line therapy in chronic phase patients. Survival analysis showed that old age, additional chromosome abnormalities, high Sokal score, and no cytogenetic response in second-line therapy had a significant poor impact (p<0.05. In conclusion, we presented the cytogenetic and molecular pattern of CML patients and demonstrated that the additional chromosome abnormality was associated with poor outcome.

  16. Decoupling, situated cognition and immersion in art.

    Science.gov (United States)

    Reboul, Anne

    2015-09-01

    Situated cognition seems incompatible with strong decoupling, where representations are deployed in the absence of their targets and are not oriented toward physical action. Yet, in art consumption, the epitome of a strongly decoupled cognitive process, the artwork is a physical part of the environment and partly controls the perception of its target by the audience, leading to immersion. Hence, art consumption combines strong decoupling with situated cognition.

    2016-03-01

    Most dental pain is caused by an organic problem such as dental caries, periodontitis, pulpitis, or trauma. Diagnosis and treatment of these symptoms are relatively straightforward. However, patients often also complain of abnormal dental pain that has a non-dental origin, whose diagnosis is challenging. Such abnormal dental pain can be categorized on the basis of its cause as referred pain, neuromodulatory pain, and neuropathic pain. When it is difficult to diagnose a patient's dental pain, these potential alternate causes should be considered. In this clinical review, we have presented a case of referred pain from the digastric muscle (Patient 1), of pulpectomized (Patient 2), and of pulpectomized pain (Patient 3) to illustrate referred, neuromodulatory, and neuropathic pain, respectively. The Patient 1 was advised muscle stretching and gentle massage of the trigger points, as well as pain relief using a nonsteroidal anti-inflammatory and the tricyclic antidepressant amitriptyline. The pain in Patient 2 was relieved completely by the tricyclic antidepressant amitriptyline. In Patient 3, the pain was controlled using either a continuous drip infusion of adenosine triphosphate or intravenous Mg2+ and lidocaine administered every 2 weeks. In each case of abnormal dental pain, the patient's diagnostic chart was used (Fig.2 and 3). Pain was satisfactorily relieved in all cases.

    In nuclear power plants, it is feared that the failure of the installations containing radioactive substances may inflict serious damage on public and workers. Therefore in nuclear power plants, the ensuring of safety is planned by supposing hypothetical accidents which are not likely to occur from engineering viewpoint, and multiple protection measures are taken in the plant constitution. In addition to the safety measures from such hardware aspect, recently in order to prevent the occurrence of accidents by using various safety-confirming means, and to detect early when any accident occurred, the development and putting in practical use of many monitoring equipments have been promoted. In such background, the development of nuclear power generation supporting system was carried out for five years since fiscal year 1980, subsidized by the Ministry of International Trade and Industry, and in this report, the technology of equipment abnormality diagnosis developed as a part of that project and the diagnostic techniques for actual plants are described. The technology of diagnosing nuclear reactor abnormality includes the diagnosis of loose metal pieces and the abnormal vibration of in-core structures. The detection and diagnosis of valve leak and the diagnosis of the deterioration of detectors are also explained. (Kako, I.)

  2. Abnormal Activity Detection Using Pyroelectric Infrared Sensors

    2016-06-01

    Full Text Available Healthy aging is one of the most important social issues. In this paper, we propose a method for abnormal activity detection without any manual labeling of the training samples. By leveraging the Field of View (FOV modulation, the spatio-temporal characteristic of human activity is encoded into low-dimension data stream generated by the ceiling-mounted Pyroelectric Infrared (PIR sensors. The similarity between normal training samples are measured based on Kullback-Leibler (KL divergence of each pair of them. The natural clustering of normal activities is discovered through a self-tuning spectral clustering algorithm with unsupervised model selection on the eigenvectors of a modified similarity matrix. Hidden Markov Models (HMMs are employed to model each cluster of normal activities and form feature vectors. One-Class Support Vector Machines (OSVMs are used to profile the normal activities and detect abnormal activities. To validate the efficacy of our method, we conducted experiments in real indoor environments. The encouraging results show that our method is able to detect abnormal activities given only the normal training samples, which aims to avoid the laborious and inconsistent data labeling process.

    2014-07-22

    Nutritional abnormalities are associated with chronic obstructive pulmonary disease with a frequency ranging from 2 to 50%, depending on the geographical area and the study design. Diagnostic tools include anthropometry, bioelectrical impedance, dual energy radioabsortiometry and deuterium dilution, being the body mass and the lean mass indices the most frequently used parameters. While the most important consequences of nutritional abnormalities are muscle dysfunction and exercise limitation, factors implicated include an imbalance between caloric intake and consumption, and between anabolic and catabolic hormones, inflammation, tobacco smoking, poor physical activity, hypoxemia, some drugs and aging/comorbidities. The most important molecular mechanism for malnutrition associated with chronic obstructive pulmonary disease appears to be the mismatching between protein synthesis and breakdown. Among the therapeutic measures proposed for these nutritional abnormalities are improvements in lifestyle and nutritional support, although the use of anabolic drugs (such as secretagogues of the growth hormone) offers a new therapeutic strategy.

    2003-06-01

    Functional facial deformities are usually described as those that impair respiration, eating, hearing, or speech. Yet facial scars and cutaneous deformities have a significant negative effect on social functionality that has been poorly documented in the scientific literature. Insurance companies are declining payments for reconstructive surgical procedures for facial deformities caused by congenital disabilities and after cancer or trauma operations that do not affect mechanical facial activity. The purpose of this study was to establish a large, sample-based evaluation of the perceived social functioning, interpersonal characteristics, and employability indices for a range of facial appearances (normal and abnormal). Adult volunteer evaluators (n = 210) provided their subjective perceptions based on facial physical appearance, and an analysis of the consequences of facial deformity on parameters of preferential treatment was performed. A two-group comparative research design rated the differences among 10 examples of digitally altered facial photographs of actual patients among various age and ethnic groups with "normal" and "abnormal" congenital deformities or posttrauma scars. Photographs of adult patients with observable congenital and posttraumatic deformities (abnormal) were digitally retouched to eliminate the stigmatic defects (normal). The normal and abnormal photographs of identical patients were evaluated by the large sample study group on nine parameters of social functioning, such as honesty, employability, attractiveness, and effectiveness, using a visual analogue rating scale. Patients with abnormal facial characteristics were rated as significantly less honest (p = 0.007), less employable (p = 0.001), less trustworthy (p = 0.01), less optimistic (p = 0.001), less effective (p = 0.02), less capable (p = 0.002), less intelligent (p = 0.03), less popular (p = 0.001), and less attractive (p = 0.001) than were the same patients with normal facial

    Numerous congenital abnormalities have been reported in association with hemivertebrae (HV). No data exist about their incidence depending on the location of the HV. From 1980 to 2003, 75 patients with 80 HV responsible for evolutive congenital scoliosis were managed by HV resection using a double approach and short anterior and posterior convex fusion. The associated abnormalities were evaluated with MRI, echocardiography and renal ultrasound. Associated genitourinary abnormalities were found in 24% of patients, cardiac abnormalities in 8% and intrathecal abnormalities in 15%. Medullar abnormalities were more frequent in case of vertebral malformations at lumbosacral level.

    1997-01-01

    This study was designed in order to evaluate in a more objective manner than visual inspection, the detection of myocardial inferior wall hypo-fixations in perfusion SPECT. We have studied 90 patients, divided into four groups: GO (7 M, 13 F, 55 ± 21 years) and G1 (9 M, 12 F, 49 ± 26 years) are groups of patients considered as normal; G2 (20 M, 3 F, 60 ± 12 years) corresponds to patients with reversible ischaemia, where the stress examination is abnormal but the resting one is close to normality; G3 (21 H, 5 F, 63 ± 8 years) includes infarcts where both examinations are definitely abnormal. Intra and inter-group statistical comparisons were first done using polar maps (Bull's eye) and an iterative method has then been developed for comparing each image of groups 1, 2 and to the mean normal data (GO). Finally, we have built a ROC (receiver operating characteristic) curves network for determining the best confidence interval and the optimal normality / abnormality criterion (number of pixels located without the confidence interval). The results are expressed in terms of sensitivity and specificity using the most favourable situation derived from the ROC curves. For 2.5 standard deviations, we obtain, for G2 (reversible injury) compared to G1, 78.3 % sensibility and 76.2 % for specificity at rest with at maximum 20 abnormal pixels as normality criterion, and at stress 81 % and 82.6 % for pixels. For G3 (permanent injury) compared to G1, the values are respectively : sensitivity = 88.5 % and specificity = 85.2 % at rest for 40 pixels; sensitivity = 92.3 % and specificity = 85.2 % at stress for 80 pixels. The method developed seems to be applicable on a wider scale, not only limited to inferior area abnormalities. It is able to optimise, for each situation, the confidence interval for an abnormal image definition and the most significant criterion, in terms of number of abnormal pixels, to detect a diseased myocardial area.

  7. Organelle and cellular abnormalities associated with hippocampal heterotopia in neonatal doublecortin knockout mice.

    Directory of Open Access Journals (Sweden)

    Reham Khalaf-Nazzal

    Full Text Available Heterotopic or aberrantly positioned cortical neurons are associated with epilepsy and intellectual disability. Various mouse models exist with forms of heterotopia, but the composition and state of cells developing in heterotopic bands has been little studied. Dcx knockout (KO mice show hippocampal CA3 pyramidal cell lamination abnormalities, appearing from the age of E17.5, and mice suffer from spontaneous epilepsy. The Dcx KO CA3 region is organized in two distinct pyramidal cell layers, resembling a heterotopic situation, and exhibits hyperexcitability. Here, we characterized the abnormally organized cells in postnatal mouse brains. Electron microscopy confirmed that the Dcx KO CA3 layers at postnatal day (P 0 are distinct and separated by an intermediate layer devoid of neuronal somata. We found that organization and cytoplasm content of pyramidal neurons in each layer were altered compared to wild type (WT cells. Less regular nuclei and differences in mitochondria and Golgi apparatuses were identified. Each Dcx KO CA3 layer at P0 contained pyramidal neurons but also other closely apposed cells, displaying different morphologies. Quantitative PCR and immunodetections revealed increased numbers of oligodendrocyte precursor cells (OPCs and interneurons in close proximity to Dcx KO pyramidal cells. Immunohistochemistry experiments also showed that caspase-3 dependent cell death was increased in the CA1 and CA3 regions of Dcx KO hippocampi at P2. Thus, unsuspected ultrastructural abnormalities and cellular heterogeneity may lead to abnormal neuronal function and survival in this model, which together may contribute to the development of hyperexcitability.

    Children of mentally ill parents are exposed to a variety of stress- and harmful life events. To which extent the mental illness of one or both parents affects their children's mental development is barely studied. Therefore, over a period of 6 months 142 patients with children below the age of 18 (n=237 children), who were admitted to the Dept. for Psychiatry and Psychotherapy 1 of the Paracelsus Medical University Salzburg, were questioned for abnormalities in their children's mental development. Additionally all these patients were assessed for their family situation, demographic data and psychiatric disorder. 38.4% (n=91) of the children showed mental abnormalities. The most common one were emotional (n=41), social (n=41) and learning (n=34) disabilities. Parental duration of the illness (p=0.001), age of the children (p=0.044), illness of both parents (p=0.008), longlasting family conflicts (p=0.003) and living with only one parent (p=0.012) were correlated significantly with mental abnormalities in children. The results confirm an increase risk for mental abnormalities in children of psychiatric patients. This risk varies with existing risk and protective factors, which can be partially influenced. Therefore children of mentally ill parents with problems in their mental development should be detected early. Even if genetic risk factors cannot be changed reducing known psychosocial risk factors and promotion protective factors can significantly influence a healthy development of these vulnerable children.

    2009-05-01

    Developmental remnants around the foramen magnum, or proatlas segmentation abnormalities, have been recorded in postmortem studies but very rarely in a clinical setting. Because of their rarity, the pathological anatomy has been misunderstood, and treatment has been fraught with failures. The objectives of this prospective study were to understand the correlative anatomy, pathology, and embryology and to recognize the clinical presentation and gain insights on the treatment and management. Our craniovertebral junction (CVJ) database started in 1977 and comprises 5200 cases. This prospective study has retrieval capabilities. Neurodiagnostic studies changed with the evolution of imaging. Seventy-two patients were recognized as having symptomatic proatlas segmentation abnormalities. Ventral bony masses from the clivus or medial occipital condyle occurred in 66% (44/72), lateral or anterolateral compressive masses in 37% (27 of 72 patients), and dorsal bony compression in 17% (12 of 72 patients). Hindbrain herniation was associated in 33%. The age at presentation was 3 to 23 years. Motor symptoms occurred in 72% (52 of 72 patients); palsies in Cranial Nerves IX, X, and XII in 33% (24 of 72 patients); and vertebrobasilar symptoms in 25% (18 of 72 patients). Trauma precipitated symptoms in 55% (40 of 72 patients). The best definition of the abnormality was demonstrated by 3-dimensional computed tomography combined with magnetic resonance imaging. Treatment was aimed at decompression of the pathology and stabilization. Remnants of the occipital vertebrae around the foramen magnum were recognized in 72 of 5200 CVJ cases (7.2%). Magnetic resonance imaging with 3-dimensional computed tomography of the CVJ provides the best definition and understanding of the lesions. Brainstem myelopathy and lower cranial nerve deficits are common clinical presentations in the first and second decades of life. Treatment is aimed at decompression of the pathology and CVJ stabilization.

    Objective: To illustrate the important complemental function of MRI in dignosing the urinary abnormalities of the fetus by analyzing MR features. Methods: MRI findings in 34 fetal urinary abnormalities were retrospectively analyzed. Results: Upper urinary tract dilatation was found in 12 cases: one case presented obstructed right renal dysplasia and was on the follow-up, postnatal MR imaging proved the duplex anomaly in one case, one case showed left PUJO on postnatal US imaging and prepared to surgery, 7 cases were normal on postnatal US imaging, 2 cases were lost to follow up. Bilateral urinary anomalies were found in 7 cases: Muhicystic renal dysplasia (n=3), Combined horseshoe kidney in 2 fetuses and bilateral renal aplasia in one case. Bilateral renal dysplasia was diagnosed in 2 cases, one was still bom and proved by autopsy and the other was lost to follow up. The case of bilateral renal agenesis displayed the appearance of sirenomelia on general specimen. The case of right renal agenesis associated contralateral kidney dyspalsia (n=1) was lost to follow up. MR imaging showed low signal intensity of lung and oligohydramnios in the bilateral anomalies. Unilateral urinary anomalies was found in 15 cases, including 9 cases of unilateral renal dysplasia. Two fetuses were aborted and 3 fetuses were proved with postnatal US or MR. One was lost to follow up; 3 cases were on the follow-up. There were 4 cases of unilateral renal agenesis, two fetuses were aborted and 2 fetuses were proved with postnatal US or MR imaging. The case of ectopic kidney was proved with postnatal US imaging. One case of urachal cyst was aborted without autopsy. In the unilateral anomalies, the volume of amniotic fluid was normal, and the fetal lung presented homogenious high signal intensity. Conclusion: As a complemental method, MRI is of great value in displaying and dignosing the urinary abnormalities of fetus. (authors)

  11. Wall motion abnormality of myocardial infarction

    Hayashi, Senji; Tsuda, Takashi; Ojima, Kenji

    1984-01-01

    By use of the gated blood pool scan, we divided the left ventricular LAO 45 image into 8 sections with the center of the volume as the basal point, and devised a method of quantitative evaluation of the regional wall motion from 2 aspects: 1) wall movement and 2) phase abnormality. To evaluate the wall movement, we obtained the following indeces from count curves of each section: 1) EF1=(end-diastolic count-end-systolic count)/ end-diastolic count, 2) EF2=(maximum count-minimum count)/maximum count, and 3) the difference of the two (EF2-EF1). As indeces of the phase abnormality, the mean value of phases of the pixels (phase characteristics) and the standard deviation (variation) of each section were calculated. Furthermore, the phase delay of each section was calculated as the difference from the earliest phase value of the 8 sections. Control values and standard deviation were obtained from 8 healthy controls. By this method, we analyzed 20 patients with old myocardial infarction. And following results were obtained: 1. Applying this method, we could evaluate the regional wall motion of the left ventricle more precisely, and we considered it would be useful clinically. 2. The abnormal regional wall motion of old myocardial infarction were classified into 4 typical forms as follows: 1) the wall movement decreased extremely. 2) the wall movement decreased, but no phase delay recognized. 3) the wall movement did not decrease, but phase delay was recognized. 4) the wall movement decreased, and phase delay was recognized.

    Introduction: CHARGE syndrome is a multisystem disorder that, in addition to Kallmann syndrome/isolated hypogonadotrophic hypogonadism, has been associated with anterior pituitary hypoplasia (APH). However, structural abnormalities such as an ectopic posterior pituitary (EPP) have not yet been described in such patients. Objective: The aims of the study were: 1) to describe the association between CHARGE syndrome and a structurally abnormal pituitary gland; and 2) to investigate whether CHD7 variants, which are identified in 65% of CHARGE patients, are common in septo-optic dysplasia /hypopituitarism. Methods: We describe 2 patients with features of CHARGE and EPP. CHD7 was sequenced in these and other patients with septo-optic dysplasia/hypopituitarism. Results: EPP, APH, and GH, TSH, and probable LH/FSH deficiency were present in 1 patient, and EPP and APH with GH, TSH, LH/FSH, and ACTH deficiency were present in another patient, both of whom had features of CHARGE syndrome. Both had variations in CHD7 that were novel and undetected in control cohorts or in the international database of CHARGE patients, but were also present in their unaffected mothers. No CHD7 variants were detected in the patients with septo-optic dysplasia/hypopituitarism without additional CHARGE features. Conclusion: We report a novel association between CHARGE syndrome and structural abnormalities of the pituitary gland in 2 patients with variations in CHD7 that are of unknown significance. However, CHD7 mutations are an uncommon cause of septo-optic dysplasia or hypopituitarism. Our data suggest the need for evaluation of pituitary function/anatomy in patients with CHARGE syndrome.

    Foreign bodies within soft tissues are common in children. They may cause a chronic inflammatory reaction that can result in abnormal findings on radiographs, including lytic or blastic osseous changes. These radiographic findings can mimic both benign and malignant processes. In cases where the history is uncertain and the foreign body is not recognized, magnetic resonance (MR) imaging can make a specific diagnosis and direct appropriate therapy. (orig.)

    1984-12-01

    In view of the lack of ionizing radiation, ability to image in a variety of planes, and high contrast resolution, magnetic resonance (MR) imaging may have a role in obstetrical management. Three fetuses with severe cerebral abnormalities were studied by MR in utero. The findings were correlated with ultrasound examinations and with autopsy results. Ventricular dilatation and progression of hydrocephalus were detected by MR. Although fetal motion may affect image quality, diagnostically useful images were obtained with imaging times of 2.5 min.

  2. Torpedo maculopathy: A primary choroidal capillary abnormality?

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available A 26-year-old healthy male patient's fundus revealed findings consistent with torpedo maculopathy. Swept-source optical coherence tomography (OCT showed a dome-shaped elevation of the retina at the level of ellipsoid zone. On OCT angiography segmented at the level of the choriocapillaris, a cluster of convoluted fine vessels was seen, and further, deeper scans of the larger choroidal vessels showed a slower flow. From these observations along with the embryological correlation of choriocapillaris development, a possibility of an abnormality preventing proper fenestration of the choriocapillaris along the horizontal raphe being responsible for this anomaly is suggested.

  4. Implementation synergies that exploit situational knowledge strategically

    DEFF Research Database (Denmark)

    Quitzau, Maj-Britt; Petersen, Jens-Phillip

    This paper illustrates how strategic and situated forms of knowledge may increase capacity to implement energy strategies in local urban development projects. Through analysis of front runner implementation projects, we show that the involved planners utilize situational learning processes...... strategically to develop more viable implementation trajectories. These findings resonate well with relational and network orienteered research in contemporary planning theory. In the selected case studies, we can see that planners deliberately seek to extend traditional planning approaches, like e.......g. regulation, with broader context‐specific learning processes. In doing so, we argue that – what we call – an implementation synergy is established by interlacing different forms of situational knowledge with strategic knowledge about how to reach a desired energy target. In conclusion, the paper identifies...

    2016-10-01

    Full Text Available Human gait analysis plays an important role in musculoskeletal disorder diagnosis. Detecting anomalies in human walking, such as shuffling gait, stiff leg or unsteady gait, can be difficult if the prior knowledge of such a gait pattern is not available. We propose an approach for detecting abnormal human gait based on a normal gait model. Instead of employing the color image, silhouette, or spatio-temporal volume, our model is created based on human joint positions (skeleton in time series. We decompose each sequence of normal gait images into gait cycles. Each human instant posture is represented by a feature vector which describes relationships between pairs of bone joints located in the lower body. Such vectors are then converted into codewords using a clustering technique. The normal human gait model is created based on multiple sequences of codewords corresponding to different gait cycles. In the detection stage, a gait cycle with normality likelihood below a threshold, which is determined automatically in the training step, is assumed as an anomaly. The experimental results on both marker-based mocap data and Kinect skeleton show that our method is very promising in distinguishing normal and abnormal gaits with an overall accuracy of 90.12%.

    Congenital heart defects represent the most common malformation at birth, occurring also in ∼50% of individuals with Down syndrome. Congenital heart defects are thought to have multifactorial etiology, but the main causes are largely unknown. We have explored the global methylation profile of fetal heart DNA in comparison to blood DNA from control subjects: an absolute correlation with the type of tissue was detected. Pathway analysis revealed a significant enrichment of differential methylation at genes related to muscle contraction and cardiomyopathies in the developing heart DNA. We have also searched for abnormal methylation profiles on developing heart-tissue DNA of syndromic and non-syndromic congenital heart defects. On average, 3 regions with aberrant methylation were detected per sample and 18 regions were found differentially methylated between groups. Several epimutations were detected in candidate genes involved in growth regulation, apoptosis and folate pathway. A likely pathogenic hypermethylation of several intragenic sites at the MSX1 gene, involved in outflow tract morphogenesis, was found in a fetus with isolated heart malformation. In addition, hypermethylation of the GATA4 gene was present in fetuses with Down syndrome with or without congenital heart defects, as well as in fetuses with isolated heart malformations. Expression deregulation of the abnormally methylated genes was detected. Our data indicate that epigenetic alterations of relevant genes are present in developing heart DNA in fetuses with both isolated and syndromic heart malformations. These epimutations likely contribute to the pathogenesis of the malformation by cis-acting effects on gene expression.

  12. Brain Abnormalities in Neuromyelitis Optica Spectrum Disorder

    Directory of Open Access Journals (Sweden)

    Woojun Kim

    2012-01-01

    Full Text Available Neuromyelitis optica (NMO is an idiopathic inflammatory syndrome of the central nervous system that is characterized by severe attacks of optic neuritis (ON and myelitis. Until recently, NMO was considered a disease without brain involvement. However, since the discovery of NMO-IgG/antiaqaporin-4 antibody, the concept of NMO was broadened to NMO spectrum disorder (NMOSD, and brain lesions are commonly recognized. Furthermore, some patients present with brain symptoms as their first manifestation and develop recurrent brain symptoms without ON or myelitis. Brain lesions with characteristic locations and configurations can be helpful in the diagnosis of NMOSD. Due to the growing recognition of brain abnormalities in NMOSD, these have been included in the NMO and NMOSD diagnostic criteria or guidelines. Recent technical developments such as diffusion tensor imaging, MR spectroscopy, and voxel-based morphometry reveal new findings related to brain abnormalities in NMOSD that were not identified using conventional MRI. This paper focuses on the incidence and characteristics of the brain lesions found in NMOSD and the symptoms that they cause. Recent studies using advanced imaging techniques are also introduced.

    2018-05-08

    Alongside various physical symptoms, patients with Cushing's disease and Cushing's syndrome display a wide variety of neuropsychiatric and cognitive symptoms, which are indicative of involvement of the central nervous system. The aim of this review is to provide an overview of the structural brain abnormalities that are associated with Cushing's disease and Cushing's syndrome and their relation to behavioral and cognitive symptomatology. In this review, we discuss the gray matter structural abnormalities found in patients with active Cushing's disease and Cushing's syndrome, the reversibility and persistence of these changes and the white matter structural changes related to Cushing's syndrome. Recent findings are of particular interest because they provide more detailed information on localization of the structural changes as well as possible insights into the underlying biological processes. Active Cushing's disease and Cushing's syndrome is related to volume reductions of the hippocampus and in a prefrontal region involving the anterior cingulate cortex (ACC) and medial frontal gyrus (MFG). Whilst there are indications that the reductions in hippocampal volume are partially reversible, the changes in the ACC and MFG appear to be more persistent. In contrast to the volumetric findings, changes in white matter connectivity are typically widespread involving multiple tracts.

  14. Functional neuroimaging abnormalities in idiopathic generalized epilepsy

    Directory of Open Access Journals (Sweden)

    Megan L. McGill

    2014-01-01

    Full Text Available Magnetic resonance imaging (MRI techniques have been used to quantitatively assess focal and network abnormalities. Idiopathic generalized epilepsy (IGE is characterized by bilateral synchronous spike–wave discharges on electroencephalography (EEG but normal clinical MRI. Dysfunctions involving the neocortex, particularly the prefrontal cortex, and thalamus likely contribute to seizure activity. To identify possible morphometric and functional differences in the brains of IGE patients and normal controls, we employed measures of thalamic volumes, cortical thickness, gray–white blurring, fractional anisotropy (FA measures from diffusion tensor imaging (DTI and fractional amplitude of low frequency fluctuations (fALFF in thalamic subregions from resting state functional MRI. Data from 27 patients with IGE and 27 age- and sex-matched controls showed similar thalamic volumes, cortical thickness and gray–white contrast. There were no differences in FA values on DTI in tracts connecting the thalamus and prefrontal cortex. Functional analysis revealed decreased fALFF in the prefrontal cortex (PFC subregion of the thalamus in patients with IGE. We provide minimum detectable effect sizes for each measure used in the study. Our analysis indicates that fMRI-based methods are more sensitive than quantitative structural techniques for characterizing brain abnormalities in IGE.

    Schizophrenia is associated with several brain deficits, as well as visual processing deficits, but clinically useful biomarkers are elusive. We hypothesized that retinal layer changes, noninvasively visualized using spectral-domain optical coherence tomography (SD-OCT), may represent a possible "window" to these abnormalities. A Leica EnvisuTM SD-OCT device was used to obtain high-resolution central foveal B-scans in both eyes of 35 patients with schizophrenia and 50 demographically matched controls. Manual retinal layer segmentation was performed to acquire individual and combined layer thickness measurements in 3 macular regions. Contrast sensitivity was measured at 3 spatial frequencies in a subgroup of each cohort. Differences were compared using adjusted linear models and significantly different layer measures in patients underwent Spearman Rank correlations with contrast sensitivity, quantified symptoms severity, disease duration, and antipsychotic medication dose. Total retinal and photoreceptor complex thickness was reduced in all regions in patients (P layer (P layer (P layer thickness (R = -.47, P = .005). Our novel findings demonstrate considerable retinal layer abnormalities in schizophrenia that are related to clinical features and visual function. With time, SD-OCT could provide easily-measurable biomarkers to facilitate clinical assessment and further our understanding of the disease.

    Most sudden cardiac problems require rapid treatment to preserve life. In this regard, electrocardiograms (ECG) shown on vital parameter monitoring systems help medical staff to detect problems. In some situations, such monitoring systems may display information in a less than convenient way for medical staff. For example, vital parameters are displayed on large screens outside the field of view of a surgeon during cardiac surgery. This may lead to losing time and to mistakes when problems occur during cardiac operations. In this paper we present a novel approach to display vital parameters such as the second derivative of the ECG rhythm and heart rate close to the field of view of a surgeon using Google Glass. As a preliminary assessment, we run an experimental study to verify the possibility for medical staff to identify abnormal ECG rhythms from Google Glass. This study compares 6 ECG rhythms readings from a 13.3 inch laptop screen and from the prism of Google Glass. Seven medical residents in internal medicine participated in the study. The preliminary results show that there is no difference between identifying these 6 ECG rhythms from the laptop screen versus Google Glass. Both allow close to perfect identification of the 6 common ECG rhythms. This shows the potential of connected glasses such as Google Glass to be useful in selected medical applications.

    This study compared pilot situation awareness across three traffic management concepts. The Concepts varied in terms of the allocation of traffic avoidance responsibility between the pilot on the flight deck, the air traffic controllers, and a conflict resolution automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to fully handle the responsibility of weather avoidance and maintaining separation between ownship and surrounding traffic. In Concept 2, pilots were not responsible for traffic separation, but were provided tools for weather and traffic avoidance. In Concept 3, flight deck tools allowed pilots to deviate for weather, but conflict detection tools were disabled. In this concept pilots were dependent on ground based automation for conflict detection and resolution. Situation awareness of the pilots was measured using online probes. Results showed that individual situation awareness was highest in Concept 1, where the pilots were most engaged, and lowest in Concept 3, where automation was heavily used. These findings suggest that for conflict resolution tasks, situation awareness is improved when pilots remain in the decision-making loop.

Effective leaders anticipate and assess change and adapt quickly and grow with the change, all while leading followers to do the same. As athletic training students' levels of readiness change, clinical instructors also need to transform their leadership styles and strategies to match the students' ever-changing observed needs in different situations. DATA SOURCES: CINAHL (1982-2002), MEDLINE (1990-2001), SPORT Discus (1949-2002), ERIC (1966-2002), and Internet Web sites were searched. Search terms included leadership, situational leadership, clinical instructors and leadership, teachers as leaders, and clinical education. DATA SYNTHESIS: Situational Leadership is presented as a leadership model to be used by clinical instructors while teaching and supervising athletic training students in the clinical setting. This model can be implemented to improve the clinical-education process. Situational leaders, eg, clinical instructors, must have the flexibility and range of skills to vary their leadership styles to match the challenges that occur while teaching athletic training students. CONCLUSIONS/RECOMMENDATIONS: This leadership style causes the leader to carry a substantial responsibility to lead while giving power away. Communication is one of the most important leadership skills to develop to become an effective leader. It is imperative for the future of the profession that certified athletic trainers continue to develop effective leadership skills to address the changing times in education and expectations of the athletic training profession.

    In the present invention, it is judged whether the operation state of equipments used in a plant are normal or not by using learning performances. That is, a plurality of monitoring parameters are measured for an equipment. Previously determined monitoring parameters are extracted. A leaning mode or a monitoring mode is selected. In the leaning mode, based on the values of previously determined monitoring parameters, values of other monitoring parameters during normal states are learned. In the monitoring mode, based on the values of the previously determined monitoring parameters, typical values of other leaned monitoring parameters are outputted. The typical values of other normal monitoring parameters after learning and the values of other parameters at the present time are compared. If the values of the other parameters at the present time are out of normal range, it is judged as abnormal, and the result is alarmed and displayed. (I.S.)

    To investigate possible altered CNS excitability in vaginismus. In 10 patients with primary idiopathic lifelong vaginismus, 10 with vulvar vestibulitis syndrome accompanied by vaginismus and healthy controls we recorded EMG activity from the levator ani (LA) and external anal sphincter (EAS) muscles and tested bulbocavernosus reflex (BCR). Pudendal-nerve somatosensory evoked potentials (SEPs) were tested after a single stimulus. Pudendal-nerve SEP recovery functions were assessed using a paired conditioning-test paradigm at interstimulus intervals (ISIs) of 5, 20 and 40ms. EMG in patients showed muscular hyperactivity at rest and reduced inhibition during straining. The BCR polysynaptic R2 had larger amplitude (pvaginismus. The neurophysiological abnormalities in patients with vaginismus indicate concomitant CNS changes in this disorder.

    The frequency and importance of the evaluation of the posterior fossa have increased significantly over the past 20 years owing to advances in neuroimaging. Nowadays, conventional and advanced neuroimaging techniques allow detailed evaluation of the complex anatomic structures within the posterior fossa. A wide spectrum of congenital abnormalities has been demonstrated, including malformations (anomalies due to an alteration of the primary developmental program caused by a genetic defect) and disruptions (anomalies due to the breakdown of a structure that had a normal developmental potential). Familiarity with the spectrum of congenital posterior fossa anomalies and their well-defined diagnostic criteria is crucial for optimal therapy, an accurate prognosis, and correct genetic counseling. The authors discuss the spectrum of posterior fossa malformations and disruptions, with emphasis on neuroimaging findings (including diagnostic criteria), neurologic presentation, systemic involvement, prognosis, and risk of recurrence.

    Computed tomography (CT) should be the imaging method of choice following plain chest radiographs when a suspected thymic abnormality requires further evaluation. Based upon a six-year experience, including the evaluation of 25 patients with thymic pathology, CT was found useful in suggesting or excluding a diagnosis of thymoma and in distinguishing thymic hyperplasis from thymoma in patients with myasthenia gravis. The thickness of the thymic lobes determined by CT was found to be a more accurate indicator of infiltrative disease (thymic hyperplasia and lymphoma) than the width. CT was helpful in differentiating benign thymic cysts from solid tumors, and in defining the extent of a thymic neoplasms. On occasion, CT may suggest the specific histologic nature of a thymic lesion

    We present our experience in 18 pediatric patients with abnormal neuronal migration. Seven cases of heterotopia of the gray matter, 7 agyria-pachygyria complexes, 1 case of polymicrogyria, 2 cases of schizencephaly and 1 case of hemimegalencephaly were diagnosed by means of ultrasonography, computed tomography and magnetic resonance. The clinical picture was reviewed in each case, with special attention to the occurrence of convulsions, psycho motor development and visual changes. In general, the greater the morphological change, the greater the neurological involvement in these patients. However, the two cases of schizencephaly presented mild clinical expression. Magnetic resonance increases the diagnostic yield in neuronal migration disorders. Nevertheless, either ultrasonography or, especially, computed tomography is useful as a first diagnostic approach in these malformative disorders. (Author)

    Accumulating evidence suggests involvement of the glutamatergic system in the biological mechanisms of posttraumatic stress disorder (PTSD), but few studies have demonstrated an association between glutamatergic system abnormalities and PTSD diagnosis or severity. We aimed to examine whether abnormalities in serum glutamate and in the glutamine/glutamate ratio were associated with PTSD diagnosis and severity in severely injured patients at risk for PTSD and major depressive disorder (MDD). This is a nested case-control study in TPOP (Tachikawa project for prevention of posttraumatic stress disorder with polyunsaturated fatty acid) trial. Diagnosis and severity of PTSD were assessed 3 months after the accidents using the Clinician-Administered PTSD Scale. The associations of glutamate levels and the glutamine/glutamate ratio with diagnosis and severity of PTSD and MDD were investigated by univariate and multiple linear regression analyses. Ninety-seven of 110 participants (88 %) completed assessments at 3 months. Serum glutamate levels were significantly higher for participants with full or partial PTSD than for participants without PTSD (p = 0.049) and for participants with MDD than for participants without MDD (p = 0.048). Multiple linear regression analyses showed serum glutamate levels were significantly positively associated with PTSD severity (p = 0.02) and MDD severity (p = 0.03). The glutamine/glutamate ratio was also significantly inversely associated with PTSD severity (p = 0.03), but not with MDD severity (p = 0.07). These findings suggest that the glutamatergic system may play a major role in the pathogenesis of PTSD and the need for new treatments targeting the glutamatergic system to be developed for PTSD.

  16. Situated learning - beyond apprenticeship and social constructionism

    DEFF Research Database (Denmark)

    Christensen, Gerd

    2016-01-01

    The aim of this paper is to discuss the theoretical and philosophical fundament of Jean Lave & Etienne Wenger’s theory of ’situated learning’. In Denmark, the theory has been categorized under as different paradigms as a theory of learning as ‘apprenticeship’ and as ‘social constructionism......’. This may seem as a theoretical discussion without any implications for an actual practice. But, as it will be argued in the paper, the perception of the theory has fundamental consequences for how it is considered to contribute to the understanding of learning and to analyses of learning in an actual...... context. The paper can, thus, be considered as not only a contribution to a narrow discussion of ‘situated learning’, but also to the wider discussion of how to conceptualize ‘learning’ as such. In addition, the paper discusses some of the analytical perspectives, which are at stake in some of the other...

    2007-01-01

    Leadership depends on the situation. Few social scientists would dispute the validity of this statement. But the statement can be interpreted in many different ways, depending, at least in part, on what one means by leadership. This article begins with a definition of leadership and a brief description of 3 historically important theories of leadership. The most recent of these, contingency theories, is argued to be most consistent with existing evidence and most relevant to professional practice. The Vroom, Yetton, and Jago contingency models of participation in decision making are described in depth, and their work provides the basis for identifying 3 distinct ways in which situational or contextual variables are relevant to both research on and the practice of leadership.

    Cyber defense competitions arising from U.S. service academy exercises, offer a platform for collecting data that can inform research that ranges from characterizing the ideal cyber warrior to describing behaviors during certain challenging cyber defense situations. This knowledge could lead to better preparation of cyber defenders in both military and civilian settings. This paper describes how one regional competition, the PRCCDC, a participant in the national CCDC program, conducted proof of concept experimentation to collect data during the annual competition for later analysis. The intent is to create an ongoing research agenda that expands on this current work and incorporates augmented cognition and gamification methods for measuring cybersecurity situational awareness under the stress of cyber attack.

    2007-01-01

    In the field of precautionary radiation protection and disaster response, the amount of information and the number of its sources is steadily increasing. Central compilation and instant availability of information for all involved authorities becomes more and more important. In this context the structured presentation of documents on a web server in terms of an ''Electronic Situation Display'' (ESD) has been established. In Germany, there are several Electronic Situation Display prototypes run by federal and state authorities for various purposes and using different technical approaches. The systems of the federal states focus on workflow management. They provide emergency log books and information on the implementation of countermeasures for disaster response authorities. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) tasked the Federal Office for Radiation Protection (BfS) to develop the Federal Electronic Situation Display (ELAN) that is mainly used as an information platform for decision making in case of nuclear emergencies. Documents containing radiological data or results from Decision Support Systems are almost automatically integrated into ELAN. Read and write permissions for users are managed by a concept of specific roles. The federal ESD and the systems of the federal states will be coordinated in order to achieve a better harmonisation. Interfaces for data exchange and data processing must be defined. Authorities of the federal states can use protected areas within the federal ESD where information is kept confidential for internal use before it is distributed to other states and federal authorities. In addition, key information of Electronic Situation Displays from the federal states can automatically be integrated into ELAN. Several task groups of the IAEA are working on the development and realization of a prototype for an information platform harmonising ESDs on international level. (orig.)

    The need for assessing internal radiation doses in emergency situations was demonstrated after accidents in Brazil, Ukraine and other countries. Lately more and more concern has been expressed regarding malevolent use of radiation and radioactive materials. The scenarios for such use are more difficult to predict than for nuclear power plant or weapons accidents. Much of the results of the work done in the IRADES project can be adopted for use in various accidental situations involving radionuclides that are not addressed in this report. If an emergency situation occurs in only one or a few of the Nordic countries, experts from the other countries could be called upon to assist in monitoring. A big advantage is then our common platform. In the Nordic countries much work has been put down on quality assurance of measurements and on training of dose assessment calculations. Attention to this was addressed at the internal dosimetry course in October 2005. Nordic emergency preparedness exercises have so far not included training of direct measurements of people in the early phase of an emergency. The aim of the IRADES project was to improve the preparedness especially for thyroid measurements. The modest financial support did not enable the participants to make big efforts but certainly acted as a much appreciated reminder of the importance of being prepared also to handle situations with malevolent use of radioactive materials. It was left to each country to decide to which extent to improve the practical skills. There is still a need for detailed national implementation plans. Measurement strategies need to be developed in each country separately taking into account national regulations, local circumstances and resources. End users of the IRADES report are the radiation protection authorities. (au)

    The main aim of this research was to investigate the decision making process in risky situations. We studied how different types of feedback on risky driving behaviors modulate risk evaluation and risk-taking. For a set of risky traffic situations, participants had to make evaluative judgments (judge the situation as risky or not) and urgent decisions (brake or not). In Experiment 1, participants received feedback with and without negative emotional content when they made risky behaviors. In Experiment 2 we investigated the independent effects of feedback and negative emotional stimuli. The results showed three important findings: First, urgent decisions were faster [F(1, 92) = 6.76, p = .01] and more cautious [F(1, 92) = 17.16, p towards more cautious responses [F(1, 111) = 14.09, p emotional stimuli had an effect only when they were presented as feedback. The results of this research increase our understanding of the processes involved in risky driving behavior and suggest efficient ways to control risk taking through the use of feedback.

    Describe the risk behaviour relationships with road safety in adolescents. Cross-sectional descriptive study. Madrid and Andalusia Regions, representative samples. The sample included 3,612 in secondary school pupils from Madrid (n=1708) and Andalusia (n=1904). The survey was carried out during May and June 2007. The data collected included sociodemographic areas (age, sex, grade, father's profession, birth place, etc.) and risk situation and behaviour (risk behaviour as driver or passenger). 16.2% of the adolescents have been involved in a dangerous situation with motorcycles during the last year. 16.7% never use a helmet when riding a motorcycle and 62% do not wear one when riding a bicycle on the road; 17.4% frequently ride a motorcycle over the speed limit and 24.5% when driving a car. There are significant differences regarding sex, grade and region (Madrid or Andalusia). There are four factors which explain 62% of the variance: drug factor, speed factor, security factor and passenger factor. Two of these have twice the probability of having a dangerous situation when riding a motorcycle: drug factor (OR=1.96; 95% CI, 1.77-2.18) and the speed factor ((OR=2.13; 95% CI, 1.92-2.36). Adolescents in higher grades and living in Andalusia were less road safety conscious. This pattern should be taken into account when designing preventive actions in Road Safety Education. 2009 Elsevier España, S.L. All rights reserved.

    To reduce the severity of injuries and the number of pedestrian deaths in traffic accidents, active safety devices providing pedestrian detection are considered effective countermeasures. The features of car-to-pedestrian collisions need to be known in detail to develop such safety devices. Because information on real-world accidents is limited, this study investigated near-miss situations captured by drive recorders installed in passenger cars. We showed similarities of the contact situation between near-miss incidents and real-world fatal pedestrian accidents in Japan. We analyzed the near-miss incident data via video capturing pedestrians crossing the road in front of forward-moving cars. Using a video frame captured by a drive recorder, the time to collision (TTC) was calculated from the car velocity and the distance between the car and pedestrian at the moment that the pedestrian initially appeared. The average TTC in the cases where pedestrians were not using a pedestrian crossing was shorter than that in the cases where pedestrians were using a pedestrian crossing. The average TTC in the cases where pedestrians emerged from behind obstructions was shorter than that in the cases where drivers had unobstructed views of the pedestrians. We propose that the specifications of the safety device for pedestrian detection and automatic braking should reflect the severe approach situation for a pedestrian and car including the TTC observed for near-miss incidents.

  4. Counterfactual Problem Solving and Situated Cognition

    Full Text Available The paper describes and interprets data of a study on counterfactual problem solving in representatives of modern industrial culture. The study was inspired by similar experiments carried out by A.R. Luria during his expedition to Central Asia. The hypothesis of our study was that representatives of modern industrial culture would solve counterfactual puzzles at a slower rate and with higher numbers of mistakes than similar non-counterfactual tasks. The experiments we conducted supported this hypothesis as well as provided us with some insights as to how to further develop it. For instance, we found no significant differences in time lag in solving counterfactual and ‘realistic’ tasks between the subjects with mathematical and the ones with liberal arts education. As an interpretation of the obtained data, we suggest a two-stage model of counterfactual problem solving: on the first stage, where situated cognition dominates, the realistic situation is transferred into the system of symbols unrelated to this very situation; on the second stage, operations are carried out within the framework of this new system of symbols.

    Recent advances in big data (BD) have focused research on the volume, velocity, veracity, and variety of data. These developments enable new opportunities in information management, visualization, machine learning, and information fusion that have potential implications for space situational awareness (SSA). In this paper, we explore some of these BD trends as applicable for SSA towards enhancing the space operating picture. The BD developments could increase in measures of performance and measures of effectiveness for future management of the space environment. The global SSA influences include resident space object (RSO) tracking and characterization, cyber protection, remote sensing, and information management. The local satellite awareness can benefit from space weather, health monitoring, and spectrum management for situation space understanding. One area in big data of importance to SSA is value - getting the correct data/information at the right time, which corresponds to SSA visualization for the operator. A SSA big data example is presented supporting disaster relief for space situation awareness, assessment, and understanding.

    Communications among MCR operators is an important factor for understanding how and how well MCR operators manage abnormal situations in NPPs. As mentioned by Ujita et al., the performance of MCR operators in emergency situations in NPPs is strongly affected by not only the cognitive process for each operator, but also by communications and collaboration among operators. Many researches have been conducted to find out the relation between the communication of human operators and the performance of them. But, it seems that few researches have been conducted on in what way the communication among MCR operators should be performed to enhance the performance of them. In this paper, we propose an analysis method for evaluating the quality of communications among MCR operators in nuclear power plants (NPPs)

    The clinical usefulness of MRI for the diagnosis of abnormal pregnancies was evaluated. Pelvic MRI was carried out on 29 cases suspected of abnormal pregnancy by ultrasonography and clinical examinations. The abnormal pregnancies were classified into three categories: (1) maternal abnormalities, (2) fetal abnormalities and (3) placental abnormalities. MRI was of great value for the diagnosis of maternal abnormalities, particularly in cases of coexistent pelvic tumor. MRI allowed diagnosis of uterine leiomyomas and dermoid cyst through its excellent tissue characterization and broad range of vision. MRI was useful in making diagnoses of fetal central nervous anomalies and fetal death, since the lack of fetal movement and the lesions were clear enough to be detected by MRI. However, anomalies in the fetal trunk or extremities could only be demonstrated, but not diagnosed, by MRI owing to its inferior spatial and time resolution. MRI showed placenta accreta and placental hematoma. Although accurate diagnosis was difficult because of their rarity, MRI revealed the hemorrhagic component of the lesions, which was not shown by ultrasonography. The author believes MRI has potential usefulness in making diagnoses of placental abnormalities through its tissue characterization. MRI was superior to ultrasonography in the soft tissue characterization, field of view, while MRI was inferior in time and spatial resolution. In summary, MRI hould be used in case of abnormal pregnancies such as pelvic tumors, fetal nervous anomalies and placental hemorrhagic lesions. MRI will become useful for the diagnosis of other abnormalities as its spatial resolution and fast scan technology advances. (author)

    There are few published data on the patterns of parenchymal imaging abnormalities in a context of cerebral venous thrombosis (CVT). The objectives of the present study were to describe the patterns of parenchymal lesions associated with CVT and to determine the lesion sites. We included 44 consecutively hospitalized patients with CVT and parenchymal lesions on magnetic resonance imaging. The diagnosis of CVT had been confirmed by magnetic resonance imaging/magnetic resonance venography. Magnetic resonance imaging patterns for CVT were retrospectively analyzed with regard to the lesion's type, shape, and site. The most frequent stroke subtype was hemorrhagic ischemia (in 56.8% of cases), followed by intracerebral hematoma (in 22.72% of cases) and nonhemorrhagic ischemia (in 20.45% of cases). Although there were no significant differences between these 3 groups with regard to the clinical and radiological characteristics, we observed a nonsignificant trend ( P =0.08) toward a shorter time interval between hospital admission and magnetic resonance imaging for nonhemorrhagic stroke. The CVT parenchymal abnormalities were centered on 6 main foci and were related to the site of venous occlusion: (1) the inferior parietal lobule (n=20; 44.5%), associated mainly with occlusion of the transverse sinus (n=10) or pure cortical veins (n=10); (2) the inferior and posterior temporal regions (n=10; 22.75%), associated mainly with occlusion of the transverse sinus (n=9); (3) the parasagittal frontal region (n=6; 13.6%), associated mainly with occlusion of the superior sagittal sinus (n=4) or the transverse sinus (n=4); (4) the thalamus (n=5; 11.3%) associated with occlusion of the straight sinus (n=5); (5) the cerebellar hemisphere (n=2; 4.5%), associated in both cases with occlusion of the transverse sinus; and (6) the deep hemispheric regions (n=3; 6.8%), associated with occlusion of the superior sagittal sinus in all cases. Parenchymal lesions caused by CVT display specific

    It has been demonstrated that the majority of secreting and nonsecreting adenomas is monoclonal in origin suggesting that these neoplasia arise from the replication of a single mutated cell, in which growth advantage results from either activation of protooncogenes or inactivation of antioncogenes. Although a large number of genes has been screened for mutations, only few genetic abnormalities have been found in pituitary tumors such as allelic deletion of chromosome 11q13 where the MEN-1 gene has been localised, and mutations in the gene encoding the alpha subunit of the stimulatory Gs and Gi2 protein. These mutations constitutively activate the alpha subunit of the Gs and Gi2 protein by inhibiting their intrinsic GTPase activity. Both Gs alpha and Gi2alpha can be considered products of protooncogenes (gsp and gip2, respectively) since gain of function mutations that activate mitogenic signals have been recognized in human tumors. Gsp oncogene is found in 30-40% of GH-secreting adenomas, in a low percentage of nonfunctioning and ACTH-secreting pituitary adenomas, in toxic thyroid adenomas and differentiated thyroid carcinomas. The same mutations, occurred early in embriogenesis, have been also identified in tissues from patients affected with the McCune Albright syndrome. These mutations result in an increased cAMP production and in the subsequent overactivation of specific pathways involved in both cell growth and specific programmes of cell differentiation. By consequence, the endocrine tumors expressing gsp oncogene retain differentiated functions. The gip2 oncogene has been identified in about 10% of nonfunctioning pituitary adenomas, in tumors of the ovary and the adrenal cortex. However, it remains to be established whether Gi proteins activate mitogenic signals in pituitary cells. Since Gi proteins are involved in mediating the effect of inhibitory neurohormones on intracellular effectors, it has been proposed that in pituitary tumors the low expression of

    Abnormal event detection, also known as anomaly detection, is one challenging task in security video surveillance. It is important to develop effective and robust movement representation models for global and local abnormal event detection to fight against factors such as occlusion and illumination change. In this paper, a new algorithm is proposed. It can locate the abnormal events on one frame, and detect the global abnormal frame. The proposed algorithm employs a sparse measurement matrix designed to represent the movement feature based on optical flow efficiently. Then, the abnormal detection mission is constructed as a one-class classification task via merely learning from the training normal samples. Experiments demonstrate that our algorithm performs well on the benchmark abnormal detection datasets against state-of-the-art methods.

    A 1-month-old boy with shortness of extremities on prenatal US was referred to our department with a provisional diagnosis of achondroplasia. His height was normal but he had short extremities and platyspondyly, premature carpal epiphyses on both hands, and short tubular bones with irregular metaphyses on radiographs. Re-evaluation of the patient at the age of 1 year revealed very short height and premature calcification of the costal cartilages and epiphyses. Spondylometaepiphyseal dysplasia (SMED), short limb-abnormal calcification type was diagnosed. This condition is a very rare autosomal recessively inherited disorder, and most of the patients die in early childhood due to neurological involvement. At the age of 2 years and 5 months, a CT scan showed narrowing of the cervical spinal canal. One month later he died suddenly because of spinal cord injury. In conclusion early diagnosis is very important because the recurrence risk is high and patients may die due to early neurological complications. The time of onset of abnormal calcifications, a diagnostic finding of the disease, is at the age of around 1 year in most patients. When abnormal calcifications are not yet present, but radiological changes associated with SMED are present, this rare disease must be considered. (orig.)

    The aims of this study were two: to compare the efficacy of fast MRI (breath-hold fast spin-echo T2-weighted and fast gradient-echo T1-weighted sequence) and ultrafast MRI (half-Fourier acquisition single-shot turbo spin-echo sequence) in evaluation of fetal central nervous system (CNS) abnormalities at late gestational age, and to compare the capability of fast MRI and ultrafast MRI to assess fetal CNS abnormalities with that of prenatal ultrasonography (US). Forty-nine women with fetuses at gestational ages of 26-39 weeks underwent fast MRI (29 patients) or ultrafast MRI (20 patients). In detection of motion artifact, visualization of the lateral and 4th ventricles, and differentiation between gray and white matter in cerebral hemispheres, ultrafast MRI was significantly superior to fast MRI (p<0.0001, Mann-Whitney U test). In 25 of 43 cases, US and MR diagnoses were the same and consistent with postnatal diagnosis. In 10 of 43 cases, MRI demonstrated findings additional to or different from those of US, and MR findings were confirmed postnatally. MRI, particularly ultrafast MRI, is useful for demonstrating CNS abnormalities in situations in which US is suggestive but not definitive. (author)

    The aim in the diagnosis of abnormal uterine bleeding (AUB) is to identify the bleeding cause, which can be classified by the PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy (and hyperplasia), Coagulopathy, Ovulatory disorders, Endometrial, Iatrogenic and Not otherwise classified) classification system. In a gynecologic setting, the first step is most often to identify structural abnormalities (PALM causes). Common diagnostic options for the identification of the PALM include ultrasonography, endometrial sampling, and hysteroscopy. These options alone or in combination are sufficient for the diagnosis of most women with AUB. Contrast sonography with saline or gel infusion, three-dimensional ultrasonography, and magnetic resonance imaging may be included. The aim of this article is to describe how a simple structured transvaginal ultrasound can be performed and implemented in the common gynecologic practice to simplify the diagnosis of AUB and determine when additional invasive investigations are required. Structured transvaginal ultrasound for the identification of the most common endometrial and myometrial abnormalities and the most common ultrasound features are described. Moreover, situations where magnetic resonance imaging may be included are described. This article proposes a diagnostic setup in premenopausal women for the classification of AUB according to the PALM-COEIN system. Moreover, a future diagnostic setup for fast-track identification of endometrial cancer in postmenopausal women based on a structured evaluation of the endometrium is described. Copyright © 2016.

    High-resolution computed tomography (HRCT) is the procedure of choice in the diagnostics of abnormalities of the middle and inner ear. It allows a detailed presentation of anatomical features and achieves the prerequisites for selection of the various therapeutic options. The highly diverse abnormalities can be described using detailed imaging analyses. Malformations with an abnormally developed modiolus are assumed to be early embryological defects, such as the classical Mondini dysplasia. The essential therapeutic option for middle ear deformities is still a cochlear implant. The domain of magnetic resonance imaging (MRI) is not only in the analysis of the cochlear nerve and for exclusion of fibrosis or ossification of the labyrinth but is also able to visualize details of isolated malformations, such as an extended vestibular aqueduct or subtle alterations to the vestibule or can visualize them better in comparison to CT. Radiological diagnostics are used not only for classification but also to recognize typical clinical problem situations and play a key role in the diagnostics of hearing disorders and selection of the optimal therapeutic procedure.

    The thyroid gland is the largest pure endocrine gland in the body and one of the organs most likely to produce clinically significant abnormalities after therapeutic external radiation. Radiation doses to the thyroid that exceed approximately 26 Gy frequently produce hypothyroidism, which may be clinically overt or subclinical, as manifested by increased serum thyrotropin and normal serum-free thyroxine concentrations. Pituitary or hypothalamic hypothyroidism may arise when the pituitary region receives doses exceeding 50 Gy with conventional, 1.8-2 Gy fractionation. Direct irradiation of the thyroid may increase the risk of Graves' disease or euthyroid Graves' opthalmopathy. Silent thyroiditis, cystic degeneration, benign adenoma, and thyroid cancer have been observed after therapeutically relevant doses of external radiation. Direct or incidental thyroid irradiation increases the risk for well-differentiated, papillary, and follicular thyroid cancer from 15- to 53-fold. Thyroid cancer risk is highest following radiation at a young age, decreases with increasing age at treatment, and increases with follow-up duration. The potentially prolonged latent period between radiation exposure and the development of thyroid dysfunction, thyroid nodularity, and thyroid cancer means that individuals who have received neck or pituitary irradiation require careful, periodic clinical and laboratory evaluation to avoid excess morbidity

    Changes in sensory function that have been described in patients with Parkinson disease (PD) can be either 'pure' disorders of conscious perception such as elevations in sensory threshold, or disorders of sensorimotor integration, in which the interaction between sensory input and motor output is altered. In this article, we review the extensive evidence for disrupted tactile, nociceptive, thermal and proprioceptive sensations in PD, as well as the influences exerted on these sensations by dopaminergic therapy and deep brain stimulation. We argue that abnormal spatial and temporal processing of sensory information produces incorrect signals for the preparation and execution of voluntary movement. Sensory deficits are likely to be a consequence of the dopaminergic denervation of the basal ganglia that is the hallmark of PD. A possible mechanism to account for somatosensory deficits is one in which disease-related dopaminergic denervation leads to a loss of response specificity, resulting in transmission of noisier and less-differentiated information to cortical regions. Changes in pain perception might have a different explanation, possibly involving disease-related effects outside the basal ganglia, including involvement of peripheral pain receptors, as well as structures such as the periaqueductal grey matter and non-dopaminergic neurotransmitter systems.

    The presence of brain dysfunction in violent offenders has been frequently examined with inconsistent results. The aim of the study was to assess the EEG of 84 violent offenders by visual inspection and frequency-domain quantitative analysis in 84 violent prisoners. Low-resolution electromagnetic tomography (LORETA) was also employed for theta band of the EEG spectra. Antisocial personality disorder (ASPD) was present in 50 of the offenders and it was absent in the remaining 34. The prevalence of EEG abnormalities, by visual inspection, was similar for both the ASPD group (82%) and non-ASPD group (79%). The brain topography of these anomalies also did not differ between groups, in contrast to results of the EEG quantitative analysis (QEEG) and LORETA that showed remarkable regional differences between both groups. QEEG analysis showed a pattern of excess of theta-delta activities and decrease of alpha band on the right fronto-temporal and left temporo-parietal regions in the ASPD group. LORETA signified an increase of theta activity (5.08 Hz) in ASPD group relative to non-ASPD group within left temporal and parietal regions. Findings indicate that QEEG analysis and techniques of source localization may reveal differences in brain electrical activity among offenders with ASPD, which was not obvious to visual inspection.

    Although abnormal saliva is a well documented finding in PWS, little is known about the saliva in these individuals. We have recently undertaken a study to characterize the salivary composition from PW patients and to see if there is any correlation with their underlying molecular diagnosis (deletion vs. disomy). We have collected whole saliva on 3 patients; 2 had normal high-resolution karyotype analysis (Cases 1 & 3) and 1 had a deletion of 15q11q13 (Case 3). For all parameters, Case 3`s values were notably different from those of his unaffected sibling. The salivary flow rates and concentrations for all 3 PW patients are similar and are significantly different from normal controls (mean {plus_minus} SE) (p<0.05). Although this data is from only 3 PW patients, it provides valuable information. First, decreased flow appears to be due to an effect of PWS and not medications since Cases 2 & 3 are not on any medications. Second, decreased flow appears to be present in younger as well as older individuals. Third, deviations from normal in the salivary composition are evident. It is possible that these alterations are concentration effects relative to a decrease in flow rate. We are currently obtaining saliva from more PW individuals to see if these alterations are present in all PW patients and whether they can be applied as a screening test.

Materials and methods: Forty admitted patients (36 women) who satisfied the 2006 criteria of Wingerchuk et al. for NMO were included in this study. All patients received a neurological examination and MRI scanning including brain and spinal cord. MRIs were classified as normal, nonspecific, multiple sclerosis-like, typical abnormalities. MS-like lesions were too few to satisfy the Barkhof et al. criteria for MS. Confluent lesions involving high AQP-4 regions were considered typical. Non-enhancing deep white matter lesions other than MS-like lesions or typical lesions were classified as nonspecific. Results: Brain MRI lesions were delineated in 12 patients (25%). Four patients (10%) had hypothalamus, brainstem or periventricle lesions. Six (15%) patients were nonspecific, and 2 (5%) patients had multiple sclerosis-like lesions. Conclusion: Brain MRIs are negative in most NMO, and brain lesions do not exclude the diagnosis of NMO. Hypothalamus, brainstem or periventricle lesions, corresponding to high sites of AQP-4 in the brain, are indicative of lesions of NMO.

  6. Normal and abnormal aging in bilinguals

    Directory of Open Access Journals (Sweden)

    Alfredo Ardila

    Full Text Available Abstract Bilinguals use two different language systems to mediate not only social communication, but also cognitive processes. Potential differences between bilinguals and monolinguals in task-solving strategies and patterns of cognitive decline during normal and abnormal aging have been suggested. Main contribution: A research review of the area suggests that normal aging is associated with increased interference between the two languages and tendency to retreat to a single language. General cognitive functioning has been found to be higher in demented bilingual patients if communication is carried out in L1 rather than in L2. Recent research has reported that bilingualism can have a protective effect during aging, attenuating the normal cognitive decline associated with aging, and delaying the onset of dementia. Conclusions: Regardless of the significant heterogeneity of bilingualism and the diversity of patterns in language use during life-span, current research suggests that bilingualism is associated with preserved cognitive test performance during aging, and potentially can have some protective effect in dementia.

  7. Abnormal parietal function in conversion paresis.

    Directory of Open Access Journals (Sweden)

    Marije van Beilen

    Full Text Available The etiology of medically unexplained symptoms such as conversion disorder is poorly understood. This is partly because the interpretation of neuroimaging results in conversion paresis has been complicated by the use of different control groups, tasks and statistical comparisons. The present study includes these different aspects in a single data set. In our study we included both normal controls and feigners to control for conversion paresis. We studied both movement execution and imagery, and we contrasted both within-group and between-group activation. Moreover, to reveal hemisphere-specific effects that have not been reported before, we performed these analyses using both flipped and unflipped data. This approach resulted in the identification of abnormal parietal activation which was specific for conversion paresis patients. Patients also showed reduced activity in the prefrontal cortex, supramarginal gyrus and precuneus, including hemisphere-specific activation that is lateralized in the same hemisphere, regardless of right- or left-sided paresis. We propose that these regions are candidates for an interface between psychological mechanisms and disturbed higher-order motor control. Our study presents an integrative neurophysiological view of the mechanisms that contribute to the etiology of this puzzling psychological disorder, which can be further investigated with other types of conversion symptoms.

    The device of the present invention can specify the leakage of primary coolants from heat transfer pipes in steam generators of a PWR type reactor in an early stage. That is, radiation detectors are disposed to, respectively, a plurality of systems of secondary main steam pipelines. Each of the places where they are disposed is designed so that the pipelines themselves have a shielding effect and radiation rays from other systems than aimed system are decayed. The dose rate changes measured by each of the detectors thus designed are compared and calculated. With such procedures, it is no more necessary to dispose collimaters. If a heat transfer pipe in a steam generator is ruptured in any of the systems to cause leakage in the secondary system, the dose rate change of the radiation detector which is nearest to the pipeline and not shielded by the pipeline itself is greatest. On the other hand, the dose rate change of other radiation detectors shielded by more than 1 to 2 pipelines is small. Accordingly, even if the amount of leakage is small, since the effect from other pipelines than the aimed system can be reduced, an abnormal system can be easily specified. (I.S.)

    Imaging plays a key role in the detection of a diaphragmatic pathology in utero. US is the screening method, but MRI is increasingly performed. Congenital diaphragmatic hernia is by far the most often diagnosed diaphragmatic pathology, but unilateral or bilateral eventration or paralysis can also be identified. Extralobar pulmonary sequestration can be located in the diaphragm and, exceptionally, diaphragmatic tumors or secondary infiltration of the diaphragm from tumors originating from an adjacent organ have been observed in utero. Congenital abnormalities of the diaphragm impair normal lung development. Prenatal imaging provides a detailed anatomical evaluation of the fetus and allows volumetric lung measurements. The comparison of these data with those from normal fetuses at the same gestational age provides information about the severity of pulmonary hypoplasia and improves predictions about the fetus's outcome. This information can help doctors and families to make decisions about management during pregnancy and after birth. We describe a wide spectrum of congenital pathologies of the diaphragm and analyze their embryological basis. Moreover, we describe their prenatal imaging findings with emphasis on MR studies, discuss their differential diagnosis and evaluate the limits of imaging methods in predicting postnatal outcome.

  12. Resource Management in Constrained Dynamic Situations

    Science.gov (United States)

    Seok, Jinwoo

    Resource management is considered in this dissertation for systems with limited resources, possibly combined with other system constraints, in unpredictably dynamic environments. Resources may represent fuel, power, capabilities, energy, and so on. Resource management is important for many practical systems; usually, resources are limited, and their use must be optimized. Furthermore, systems are often constrained, and constraints must be satisfied for safe operation. Simplistic resource management can result in poor use of resources and failure of the system. Furthermore, many real-world situations involve dynamic environments. Many traditional problems are formulated based on the assumptions of given probabilities or perfect knowledge of future events. However, in many cases, the future is completely unknown, and information on or probabilities about future events are not available. In other words, we operate in unpredictably dynamic situations. Thus, a method is needed to handle dynamic situations without knowledge of the future, but few formal methods have been developed to address them. Thus, the goal is to design resource management methods for constrained systems, with limited resources, in unpredictably dynamic environments. To this end, resource management is organized hierarchically into two levels: 1) planning, and 2) control. In the planning level, the set of tasks to be performed is scheduled based on limited resources to maximize resource usage in unpredictably dynamic environments. In the control level, the system controller is designed to follow the schedule by considering all the system constraints for safe and efficient operation. Consequently, this dissertation is mainly divided into two parts: 1) planning level design, based on finite state machines, and 2) control level methods, based on model predictive control. We define a recomposable restricted finite state machine to handle limited resource situations and unpredictably dynamic environments

    The Energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event which the Nuclear Regulatory Commission determines to be significant from the standpoint of public health or safety and requires a quarterly report of such events to be made to Congress. For this reporting period, there was one abnormal occurrence at nuclear power plants licensed to operate involving significant deficiencies in management controls at Slurry Nuclear Power Station. There was one abnormal occurrence under other NRC-issued licenses; the event involved a medical therapy misadministration. One other abnormal occurrence, involving industrial radiography overexposures, was reported by an Agreement State (Texas). 40 refs

    Cigarette smoking is associated with emphysema and radiographic interstitial lung abnormalities. The degree to which interstitial lung abnormalities are associated with reduced total lung capacity and the extent of emphysema is not known. We looked for interstitial lung abnormalities in 2416 (96%) of 2508 high-resolution computed tomographic (HRCT) scans of the lung obtained from a cohort of smokers. We used linear and logistic regression to evaluate the associations between interstitial lung abnormalities and HRCT measurements of total lung capacity and emphysema. Interstitial lung abnormalities were present in 194 (8%) of the 2416 HRCT scans evaluated. In statistical models adjusting for relevant covariates, interstitial lung abnormalities were associated with reduced total lung capacity (-0.444 liters; 95% confidence interval [CI], -0.596 to -0.292; Ppulmonary disease (COPD) (odds ratio, 0.53; 95% CI, 0.37 to 0.76; P<0.001). The effect of interstitial lung abnormalities on total lung capacity and emphysema was dependent on COPD status (P<0.02 for the interactions). Interstitial lung abnormalities were positively associated with both greater exposure to tobacco smoke and current smoking. In smokers, interstitial lung abnormalities--which were present on about 1 of every 12 HRCT scans--were associated with reduced total lung capacity and a lesser amount of emphysema.

    To determine the frequency of metabolic abnormalities in the serum and urine of patients with urinary stones disease. Two hundred patients with either multiple or recurrent urolithiasis diagnosed on ultrasonography and intravenous urography were included in this study. 24 hour urine sample were collected from each patient and sent for PH, specific gravity, Creatinine, uric acid, calcium, phosphate, oxalate, citrate and magnesium. In addition, blood sample of each patient was also sent for serum levels of urea, creatinine, uric acid, phosphate and calcium. Mean age of patients was 38 ± 7.75 years with male to female ratio of 2:1. The main presenting complaint was lumber pain and 82.5% patients were found to have calcium oxalate stones on chemical analysis. Metabolic abnormalities were found in 90.5% patients, whereas there were no metabolic abnormalities in 19 (9.5%) patients. Forty patients (21.5%) only had one metabolic abnormality and 157 (78.5%) patients had multiple metabolic abnormalities. Hyperoxaluria was the most commonly observed metabolic abnormality and was found in 64.5% patients. Other significant metabolic abnormalities were hypercalciuria, Hypercalcemia, hypocitraturia and hyperuricemia. This study concludes that frequency of metabolic abnormalities is very high in patients with urolithiasis and hyperoxaluria, hypercalciuria and hypocitraturia are the most important metabolic abnormalities observed in these patients.

    Human learners can resolve referential ambiguity and discover the relationships between words and meanings through a cross-situational learning (CSL) strategy. Some people with aphasia (PWA) can learn word-referent pairings under referential uncertainty supported by online feedback. However, it remains unknown whether PWA can learn new words cross-situationally and if such learning ability is supported by statistical learning (SL) mechanisms. The present study examined whether PWA can learn novel word-referent mappings in a CSL task without feedback. We also studied whether CSL is related to SL in PWA and neurologically healthy individuals. We further examined whether aphasia severity, phonological processing and verbal short-term memory (STM) predict CSL in aphasia, and also whether individual differences in verbal STM modulate CSL in healthy older adults. Sixteen people with chronic aphasia underwent a CSL task that involved exposure to a series of individually ambiguous learning trials and a SL task that taps speech segmentation. Their learning ability was compared to 18 older controls and 39 young adults recruited for task validation. CSL in the aphasia group was below the older controls and young adults and took place at a slower rate. Importantly, we found a strong association between SL and CSL performance in all three groups. CSL was modulated by aphasia severity in the aphasia group, and by verbal STM capacity in the older controls. Our findings indicate that some PWA can preserve the ability to learn new word-referent associations cross-situationally. We suggest that both PWA and neurologically intact individuals may rely on SL mechanisms to achieve CSL and that verbal STM also influences CSL. These findings contribute to the ongoing debate on the cognitive mechanisms underlying this learning ability. Copyright © 2017 Elsevier Ltd. All rights reserved.

  20. Applying Cognitive Fusion to Space Situational Awareness

    Science.gov (United States)

    Ingram, S.; Shaw, M.; Chan, M.

    With recent increases in capability and frequency of rocket launches from countries across the world, maintaining a state-of-the-art Space Situational Awareness model is all the more necessary. We propose a fusion of real-time, natural language processing capability provided by IBM cognitive services with ground-based sensor data of positions and trajectories of satellites in all earth orbits. We believe such insight provided by cognitive services could help determine context to missile launches, help predict when a satellite of interest could be in danger, either by accident or by intent, and could alert interested parties to the perceived threat. We seek to implement an improved Space Situational Awareness model by developing a dynamic factor graph model informed by the fusion of ground-based ”structured” sensor data with ”unstructured” data from the public domain, such as news articles, blogs, and social media, in real time. To this end, we employ IBM’s Cognitive services, specifically, Watson Discovery. Watson Discovery allows real-time natural language processing of text including entity extraction, keyword search, taxonomy classification, concept tagging, relation extraction, sentiment analysis, and emotion analysis. We present various scenarios that demonstrate the utility of this new Space Situational Awareness model, each of which combine past structured information with related open source data. We demonstrate that should the model come to estimate a satellite is ”of interest”, it will indicate it as so, based on the most pertinent data, such as a reading from a sensor or by information available online. We present and discuss the most recent iterations of the model for satellites currently available on Space-Track.org.

Further technical and physical conditions are considered in the following six chapters, including environmental and safety aspects. A prognosis for energy demand in the Netherlands until the end of the century is presented and five different scenarios are discussed, as means of supplying this demand. Nuclear energy is one of the sources considered throughout the text. (C.F.)

  4. The power situation in Mid-Norway

    International Nuclear Information System (INIS)

    2006-01-01

    The strained power situation in Mid-Norway is in broad terms an energy problem, and the situation is especially precarious in the county of Moere og Romsdal. There is a risk that even in normal years, there will be insufficient energy supply unless new measures are implemented. There is a 50 percent chance that the situation will become more strained than in normal years. In the long term there is a possibility to increase the capacity of the system by increasing the import capacity as well as the production, but this is not realistic before 2011. A gas work at Tjeldbergodden can at the earliest be operative in 2011. The gas work at Skogn can at the earliest be operative in 2009, and needs to be accompanied by fortifications in the distribution net in order to help the situation in Moere og Romsdal. In short term the import capacity to the region will be reduced, and there are limits to how much new production capacity that can be taken in. Therefore, measures have to be made in order to reduce the consumption and increase the import. To make sure the measures will have satisfactory effect, they need to be implemented soon, so they can have effect over a longer period. It is limited how big reduction one can expect from the normal supply consumption. It is estimated that the consumption can be reduced by 10 percent at the maximum, by the use of high prices in the area, but this requires that the consumers expect a prolonged level of high energy prices at 0,80 Nok/kWh, and in addition short-term price fluctuations. Energy-intensive industry may find it profitable to reduce the consumption at prices below 0,80 Nok/kWh, but the potential for this is probably small in Moere og Romsdal. In a dry year it will hardly be possible to meet the energy demand without resorting to measures and in worst case rationing. The costs of rationing are substantially higher than the cost of backup power plants

    The first biosimilar version of a biologic agent used to treat psoriasis (infliximab) entered the Spanish market on February 16 of this year, and more biosimilars can be expected to follow in the coming months and years. Logically, this new situation will have economic repercussions and alter prescribing patterns among dermatologists. In this article, we review regulatory issues related to the approval of biosimilars, with a particular focus on the situation in the European Union. We will examine analytical characterization studies and special considerations for clinical trials with biosimilars, and also look at several somewhat contentious issues, such as the extrapolation of indications, interchangeability, and automatic substitution. Finally, we will review the biosimilars with indications for psoriasis currently in the clinical development pipeline and assess their potential to offer comparable efficacy and safety to the reference product while contributing to the sustainability of the public health care system.

    In 1953, President Eisenhower announced the U.S. ''Atoms for Peace'' program. After slightly more than 30 years, there are in operation, under construction or on order more than 400,000 MW of commercial nuclear power generation capacity located in 35 nations, representing a total investment around a trillion U.S. dollars. The situation is noteworthy in terms of the rate of technical development, deployment and transfer, the magnitude of the financial investment, economic benefits, the favorable impact on public health and safety, and the usual and positive character of cooperation among all concerned. The fundamentals of nuclear power generation with regard to economics, safety and environmental impact are likely to favor the increased use of nuclear power. The future prospect of the nuclear power in the U.S. also will be clarified positively. In many ways, U.S. commercial nuclear power continues to benefit from the Navy nuclear propulsion program. The prospect of supply demand situation in the conversion, enrichment and fabrication of uranium fuel is explained. The amount of spent fuel arising in OECD countries and their storage capability up to 2000 are shown, and the storage capability projected is well in excess. (Kako, I.)

    This publication proposes an overview of the situation of the Fukushima-Daiichi nuclear power station, four years after the accident. It addresses how the situation is managed in terms of evacuation of nuclear fuels, of storage of contaminated water, and of temporary storage of radioactive wastes produced by decontamination activities. It addresses the decontamination of the environment and the return of populations: progress of decontamination, return of populations, and absence of contamination of food products. The next part addresses the perspectives for the Japanese nuclear sector: a strengthened nuclear safety authority, reactors ready to start up again (some reactors seem to be able to be authorized to soon start up again). It describes how French technology is involved at the service of Fukushima-Daiichi through the Onet Technologies project by the CEA (a remote controlled laser cutting process). It evokes the evolutions of safety requirements in France after the Fukushima accident, notably with the introduction of the hard core notion, and of the FARN or Fast Nuclear Task Force

  14. Rational group decision making in risk situations

    International Nuclear Information System (INIS)

    Yoon, M.H.

    1987-01-01

    Risk management has received increasing attention recently as methods of quantifying risk have been evolving. This is considered a legitimate tendency in the context of the entirety of risk evaluation which connotes both risk quantification and decisions making thereon. A risk-free society does not appear possible; neither could one have zero competing risks or cost versus benefit resulting out of a risk-abatement effort. What further complicates the risk-decision problem is that there exists more than a single decision maker, who claim their own interests associated with risk decision. Furthermore, their risk perceptions are not at all same that the threshold risk levels for a particular actions are varying. In this dissertation, a brief survey on existing action levels for various sort of risk situations including carcinogens, toxic chemicals, etc., is reported on, with emphasis on nuclear risk situation. A decision theoretic approach is then adopted in both individual and group-level risk management. For the purpose of exemplification, multiplicative utility theory is applied for nuclear power risk; attributes derived for this specific purpose are discussed

    An assessment of the Radiation Protection of Emergency Exposure Situations in Ghana was carried out in relation to documents provided by the International Atomic Energy Agency (IAEA). As realized in the document of the “Method for Developing Arrangements for Response to a Nuclear or Radiological Emergency” of the IAEA, the National Nuclear and Radiological Emergency Response Plan (NNRERP) of Ghana also discusses the Infrastructural and Functional Requirements necessary for the intervention of a nuclear or radiological emergency. The NNRERP describes the concept of operations for a response designed to facilitate the delivery of coordinated assistance to government authorities such as the National Disaster Management Organisation (NADMO), the Radiation Protection Board (RPB) and other participating organizations. From the NNRERP, practices in Ghana, fall into emergency planning category III and IV. As part of the planning measures, one of Ghana Atomic Energy Commission’s primary functions is to provide technical support with a mechanism for timely, interagency coordination of advice and recommendations to NADMO concerning protective actions, environmental concerns, health matters and other related matters. It has been realized from this assessment that there is an urgent need to upgrade infrastructure with logistics for training, exercises and drills to achieve its optimum expectations which will eventually lead to high level of confidence in meeting the standard of a Radiation Protection Programme in Emergency Exposure Situations.

    Leprosy is a chronic dermato-neurological disease caused by Mycobacterium leprae infection. In 2016, more than 200,000 new cases of leprosy were detected around the world, representing the most frequent cause of infectious irreversible deformities and disabilities. In the present work, we demonstrate a consistent procoagulant profile on 40 reactional and non-reactional multibacillary leprosy patients. A retrospective analysis in search of signs of coagulation abnormalities among 638 leprosy patients identified 35 leprosy patients (5.48%) which displayed a characteristic lipid-like clot formed between blood clot and serum during serum harvesting, herein named 'leprosum clot'. Most of these patients (n = 16, 45.7%) belonged to the lepromatous leprosy pole of the disease. In addition, formation of the leprosum clot was directly correlated with increased plasma levels of soluble tissue factor and von Willebrand factor. High performance thin layer chromatography demonstrated a high content of neutral lipids in the leprosum clot, and proteomic analysis demonstrated that the leprosum clot presented in these patients is highly enriched in fibrin. Remarkably, differential 2D-proteomics analysis between leprosum clots and control clots identified two proteins present only in leprosy patients clots: complement component 3 and 4 and inter-alpha-trypsin inhibitor family heavy chain-related protein (IHRP). In agreement with those observations we demonstrated that M. leprae induces hepatocytes release of IHRP in vitro. We demonstrated that leprosy MB patients develop a procoagulant status due to high levels of plasmatic fibrinogen, anti-cardiolipin antibodies, von Willebrand factor and soluble tissue factor. We propose that some of these components, fibrinogen for example, presents potential as predictive biomarkers of leprosy reactions, generating tools for earlier diagnosis and treatment of these events.

  1. Management of roads with abnormal radiation

    2002-01-01

    Several asphalt concrete (AC) roads in Taoyuan County of Taiwan were found radioactively abnormal in 1994. Atomic Energy Council (AEC), the regulatory agency, was asked to take the samples, to perform the radiochemical analysis and dose evaluation as well as to investigate the source of contamination. The cause of high radiation was due to high uranium and thorium concentration slag used in the AC. The dose rate was approximately 1 μSv/hr at the road surface. The maximum annual dose received by pedestrians was estimated at 0.13 mSv (2.5% of annual dose limit of 5 mSv for the public), or approximately 1/15 of the value of annual natural background radiation in the Taiwan area. Consequently, the AEC suggested that there was no need to implement engineering remedy measures to remove the AC surface of the roads. However, upon consideration of socioeconomic condition and public opinion, the local government still decided to remove the contaminated surface of these roads. The AEC helped to formulate the operational procedures for removal and disposal of the AC including the radiation protection program and the disposal site. To date, all the contaminated AC surface of the roads was removed and properly disposed. The contaminated AC roads are a typical example of improper disposal of wastes containing Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM). A new regulation was promulgated by AEC recently to limit the use of slag, coal ash or any other industrial wastes unless its radiation or activity level is below the limit. (author)

  2. Surrogate Motherhood and Abortion for Fetal Abnormality.

    Science.gov (United States)

    Walker, Ruth; van Zyl, Liezl

    2015-10-01

    A diagnosis of fetal abnormality presents parents with a difficult - even tragic - moral dilemma. Where this diagnosis is made in the context of surrogate motherhood there is an added difficulty, namely that it is not obvious who should be involved in making decisions about abortion, for the person who would normally have the right to decide - the pregnant woman - does not intend to raise the child. This raises the question: To what extent, if at all, should the intended parents be involved in decision-making? In commercial surrogacy it is thought that as part of the contractual agreement the intended parents acquire the right to make this decision. By contrast, in altruistic surrogacy the pregnant woman retains the right to make these decisions, but the intended parents are free to decide not to adopt the child. We argue that both these strategies are morally unsound, and that the problems encountered serve to highlight more fundamental defects within the commercial and altruistic models, as well as in the legal and institutional frameworks that support them. We argue in favour of the professional model, which acknowledges the rights and responsibilities of both parties and provides a legal and institutional framework that supports good decision-making. In particular, the professional model acknowledges the surrogate's right to decide whether to undergo an abortion, and the intended parents' obligation to accept legal custody of the child. While not solving all the problems that arise in surrogacy, the model provides a framework that supports good decision-making. © 2015 John Wiley & Sons Ltd.

    Williams-Beuren syndrome (WBS, OMIM-194050) is a neurodevelopmental disorder with multisystemic manifestations caused by a 1.55-1.83 Mb deletion at 7q11.23 including 26-28 genes. Reported endocrine and metabolic abnormalities include transient hypercalcaemia of infancy, subclinical hypothyroidism in ∼ 30% of children and impaired glucose tolerance in ∼ 75% of adult individuals. The purpose of this study was to further study metabolic alterations in patients with WBS, as well as in several mouse models, to establish potential candidate genes. We analysed several metabolic parameters in a cohort of 154 individuals with WBS (data available from 69 to 151 cases per parameter), as well as in several mouse models with complete and partial deletions of the orthologous WBS locus, and searched for causative genes and potential modifiers. Triglyceride plasma levels were significantly decreased in individuals with WBS while cholesterol levels were slightly decreased compared with controls. Hyperbilirubinemia, mostly unconjugated, was found in 18.3% of WBS cases and correlated with subclinical hypothyroidism and hypotriglyceridemia, suggesting common pathogenic mechanisms. Haploinsufficiency at MLXIPL and increased penetrance for hypomorphic alleles at the UGT1A1 gene promoter might underlie the lipid and bilirubin alterations. Other disturbances included increased protein and iron levels, as well as the known subclinical hypothyroidism and glucose intolerance. Our results show that several unreported biochemical alterations, related to haploinsufficiency for specific genes at 7q11.23, are relatively common in WBS. The early diagnosis, follow-up and management of these metabolic disturbances could prevent long-term complications in this disorder. Published by the BMJ Publishing Group Limited.

    System concepts for network enabled image-based ISR (intelligence, surveillance, reconnaissance) is the major mission of Fraunhofer IITB's applied research in the area of defence and security solutions. For the TechDemo08 as part of the NATO CNAD POW Defence against terrorism Fraunhofer IITB advanced a new multi display concept to handle the shear amount and high complexity of ISR data acquired by networked, distributed surveillance systems with the objective to support the generation of a common situation picture. Amount and Complexity of ISR data demands an innovative man-machine interface concept for humans to deal with it. The IITB's concept is the Digital Map & Situation Surface. This concept offers to the user a coherent multi display environment combining a horizontal surface for the situation overview from the bird's eye view, an attached vertical display for collateral information and so-called foveatablets as personalized magic lenses in order to obtain high resolved and role-specific information about a focused areaof- interest and to interact with it. In the context of TechDemo08 the Digital Map & Situation Surface served as workspace for team-based situation visualization and analysis. Multiple sea- and landside surveillance components were connected to the system.

  6. Parental decision-making after ultrasound diagnosis of a serious foetal abnormality.

    The purpose of this article is to provide clinicians who are involved in the field of foetal medicine with a comprehensive overview of theories that are relevant for the parental decision-making process after ultrasound diagnosis of a serious foetal abnormality. Since little data are available of parental decision-making after ultrasound diagnosis of foetal abnormality, we reviewed the literature on parental decision-making in genetic counselling of couples at increased genetic risk together with the literature on general decision-making theories. The findings were linked to the specific situation of parental decision-making after an ultrasound diagnosis of foetal abnormality. Based on genetic counselling studies, several cognitive mechanisms play a role in parental decision-making regarding future pregnancies. Parents often have a binary perception of risk. Probabilistic information is translated into two options: the child will or will not be affected. The graduality of chance seems to be of little importance in this process. Instead, the focus shifts to the possible consequences for future family life. General decision-making theories often focus on rationality and coherence of the decision-making process. However, studies of both the influence of framing and the influence of stress indicate that emotional mechanisms can have an important and beneficial function in the decision-making process. Cognitive mechanisms that are elicited by emotions and that are not necessarily rational can have an important and beneficial function in parental decision-making after ultrasound diagnosis of a foetal abnormality. Consequently, the process of parental decision-making should not solely be assessed on the basis of its rationality, but also on the basis of the parental emotional outcome. Copyright (c) 2005 S.

    Section 208 of the Energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event which the Nuclear Regulatory Commission determines to be significant from the standpoint of public health or safety and requires a quarterly report of such events to be made to Congress. This report, the eighth in the series, covers the period from January 1 to March 31, 1977. The NRC has determined that during this period: there were no abnormal occurrences at the 63 nuclear power plants licensed to operate; there were no abnormal occurrences at fuel cycle facilities (other than nuclear power plants); and there was one abnormal occurrence at other licensee facilities. The event involved an inadvertent radiation exposure to two painters while working in an area where industrial radiography was being performed. This report also contains information updating previously reported abnormal occurrences

  18. Report to Congress on abnormal occurrences, January--March 1989

    Section 208 of the Energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event which the Nuclear Regulatory Commission determines to be significant from the standpoint of public health and safety and requires a Quarterly report of such events to be made to Congress. This report covers the period January 1 to March 31, 1989. For this reporting period, there were two abnormal occurrences at nuclear power plants licensed to operate. The first had generic implications and involved a plug failure resulting in a steam generator tube leak at North Anna Unit 1. The second involved a steam generator tube rupture at McGuire Unit 1. There were three abnormal occurrences under other NRC-issued licenses. Two involved medical therapy misadministrations and one involved a medical diagnostic misadministration. There were no abnormal occurrences reported by the Agreement States. The report also contains information updating some previously reported abnormal occurrences

    Haematological, ocular and skeletal abnormalities were documented in a samoyed male and its five offspring. Haematological abnormalities, found in repeated tests in all the dogs, included marked eosinophilia, eosinophilic bands and absence of Barr bodies. Two of the dogs had bilateral buphthalmia, retinal detachments and other ocular abnormalities. Three of the dogs had skeletal abnormalities including chondrodysplasia (dwarfism) and brachygnathia (undershot jaw). A similar combination of inherited skeletal and ocular disorders, without the haematological abnormalities, has been described in samoyeds. Acquired causes for the haematological findings, which are similar to the inherited Pelger-Huët anomaly described in several species, have been eliminated. Eosinophilic bands and scarcity of Barr bodies could be a marker, or a previously unreported manifestation, of an inherited disorder in samoyeds

    Section 208 of the Energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event which the Nuclear Regulatory Commission determines to be significant from the standpoint of public health or safety and requires a quarterly report of such events to be made to Congress. This report covers the period from April 1 to June 30, 1988. For this reporting period, there were no abnormal occurrences at nuclear power plants licensed to operate. There were two abnormal occurrences at other NRC licensees: a significant breakdown in management and procedural controls at a medical facility and a medical diagnostic misadministration. There was one abnormal occurrence reported by an Agreement State (Texas) involving radioactive material released during a transportation accident. The report also contains information updating some previously reported abnormal occurrences
