    This paper reports that the computer system for NPP personnel training was developed for training centers in the Soviet Union. The system should be considered as the first step in training, taking into account that further steps are to be devoted to part-task and full scope simulator training. The training room consists of 8-12 IBM PC/AT personal computers combined into a network. A trainee accesses the system in a dialor manner. Software enables the instructor to determine the trainee's progress in different subjects of the program. The quality of any trainee preparedness may be evaluated by Knowledge Control operation. Simplified dynamic models are adopted for separate areas of the program. For example, the system of neutron flux monitoring has a dedicated model. Currently, training, requalification and support of professional qualifications of nuclear power plant operators is being emphasized. A significant number of emergency situations during work are occurring due to operator errors. Based on data from September-October 1989, more than half of all unplanned drops in power and stoppages of power plants were due to operator error. As a comparison, problems due to equipment malfunction accounted for no more than a third of the total. The role of personnel, especially of the operators, is significant during normal operations, since energy production costs as well as losses are influenced by the capability of the staff. These facts all point to the importance of quality training of personnel

    Persons who are exposed to ionizing radiation at their workplace have to be trained in radiation protection. According to the Radiation Protection Ordinance the person with responsibility in radiation protection has to guarantee that the training is performed twice a year. Our training material was created especially for the persons defined in the Radiation Protection Ordinance and the X-ray Ordinance. It enables persons who teach (generally the radiation protection officer) to perform the training without tedious study and preparation of the documents. Our material is not just another textbook for radiation protection but rather a folder with colour transparencies and explanatory texts which make a difference in volume and price in comparison to other existing materials.

    In the Peru, according to the current regulations, people that work with ionizing radiations should have an authorization (individual license), which is granted by the Technical Office of the National Authority that is the technical body of the Instituto Peruano de Energia Nuclear (IPEN) manager of the control of ionizing radiations in the country. The individual license is obtained after the applicant fulfills the requested requirements, as having safety knowledge and radiological protection. Since its founding in 1972, the Centro Superior de Estudios Nucleares (CSEN) of the IPEN has carried out diverse training courses in order to that people can work in a safe way with ionizing radiations in medicine, industry and research, until the year 2013 have been organized 2231 courses that have allowed the training of 26213 people. The courses are organized according to the specific work that is carried out with radiations (medical radio-diagnostic, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear meters, logging while drilling, etc.). In their majority the courses are directed to people that will make use of radiations for first time, but refresher courses are also granted in the topic. The CSEN also carries out the Master degree programs highlighting the Second Professional Specialization in Radiological Protection carried out from the year 2004 with the support of the National University of Engineering. To the present has been carried out 2 programs and there is other being developed. In this work is shown the historical evolution of the radiological protection courses as well as the important thing that they are to work in a safe way in the country. (Author)

    Radiation Protection Training is an important component of Radiation Protection and serves for human radiation safety. According to the Lithuanian Law on Radiation Protection the legal persons and enterprises without the status of legal persons to conduct practices with sources or which workers work under exposure must organize at their own expenses a compulsory training and assessment of knowledge of the workers engaging in activities with the sources and radiation protection officers. Such training has been started in 1999. In Lithuania there are few institutions executing Radiation Protection training. Under requirements of legal act On Frequency and Procedure of Compulsory Training and Assessment Knowledge of the Workers Engage in Activities with the Sources of Ionising Radiation and Radiation Protection Officers these institutions have to prepare and coordinate training programs with the Radiation Protection Center. There are adopted different educating programs for Radiation Protection Training to the Workers and Radiation Protection Officers depending on character of work and danger of sources. The duration of Training is from 30 to 270 hours. The Training shall be renewed every five years passing 30 hors course. To ensure the adequate quality of training a great deal of attention is paid to qualifying the lectures. For this purpose, it was established an Evaluation commission to estimate the adequacy of lecturer's knowledge to requirements of Training programs. After passing exams the lectures get the qualification confirming certificates. The main task of our days is to establish and arrange the National Training Centre on Radiation Protection Training that would satisfy requirements and recommendations of legal documents of IAEA and EU for such kind of institutions of institutions.

    Many Member States are developing or already have developed their own national training programmes. The IAEA is actively involved in promoting training in radiological protection, and this report has been prepared to provide the guidance that may be required in this development. The original version of the report on this subject was published in 1964 as Technical Reports Series No. 31 entitled ''Training in Radiological Protection: Curricula and Programming''. In 1975 a second version was published entitled ''Training in Radiological Protection for Nuclear Programmes'' as Technical Reports Series No. 166. This publication is intended mainly for use by persons who are responsible for organizing training programmes in radiation protection. It also reflects the policy of the Agency to have continuing standardized training in radiation protection. In addition to a small change in the title of the report, some concepts and ideas which are no longer applicable have been omitted and new information included. An important part of this report is the list of courses now offered in many Member States

    1999-01-01

    Program in radiological equipment has incorporated more powerful x-ray sources into the standard Fluoroscopy and CT systems. Expanding use of interventional procedures carries extensive use of fluoroscopy and CT which are both associated with excessive radiation exposure to the patient and personnel. During cases of Intravenous CT Angiography and direct Intraarterial CT Angiography, one may substitute a substantial number of diagnostic angiography checks. Basic training in interventional radiology hardly includes some of the fundamentals of radiation protection. Radiation Protection in Interventional Radiology must be implemented in daily practice and become an integral part of procedure planning strategy in each and every case. Interventional radiological most master all modern imaging modalities in order to choose the most effective, but least hazardous one. In addition, one must be able to use various imaging techniques (Fluoroscopy, CTA, MM and US) as a stand-alone method, as well as combine two techniques or more. Training programs for fellows: K-based simulation of procedures and radiation protection. Special attention should be taken in the training institutions and a basic training in radiation protection is advised before the trainee is involved in the practical work. Amendment of techniques for balloon and stent deployment with minimal use of fluoroscopy. Attention to the differences between radiation protection in cardiovascular and nonvascular radiology with special measures that must be taken for each one of them (i.e., peripheral angiography vs. stenting, Endo luminal Aortic Stent Graft, or nonvascular procedures such as biliary or endo urological stenting or biliary intervention). A special emphasis should be put on the training techniques of Interventional Radiologists, both beginners and experienced. Patient dose monitoring by maintaining records of fluoroscopic time is better with non-reset timer, but is optional. Lee of automated systems that

    The automatic vehicle protection system of the H-Bahn at the Universtiy of Dortmund is responsible for fail-safe operating of the automatic vehicles. Its functions are protection of vehicle operation and protection of passengers boarding and leaving the vehicles. These functions are managed decentrally by two fail-safe operating controllers. Besides the well-known relay-techniques of railway-fail-safe systems, electronics are applied which are based on safe operating URTL-microcontrollers. These are controlled by software stored in EPROMs. A connection link using glass-fibres serves for safe data-exchange between the two fail-safe operating controllers. The experts' favourable reports on 'train protection and safety during passenger processing' were completed in March 84; thus, transportation of passengers could start in April 84.

    Among the several components of distribution systems, protection devices present a fundamental importance, since they aim at keeping the physical integrity not only of the system equipment, but also of the electricians' team and the population in general. The existing tools today in the market that carry out the making of protection studies basically draw curves, and need direct user's interference for the protection devices adjustment and coordination analyses of selectivity, being susceptible to the user's mistakes and not always considering the best technical and economical application. In Brazil, the correct application of the protection devices demand a high amount of time, being extremely laborious due to the great number of devices (around 200 devices), besides the very dynamic behaviour of distribution networks and the need for constant system expansion. This article presents a computational tool developed with the objective of automatically determining the adjustments of all protection devices in the distribution networks to obtain the best technical application, optimizing its performance and making easier protection studies.

  14. Model-Based Reasoning in Humans Becomes Automatic with Training.

    2015-09-01

    Full Text Available Model-based and model-free reinforcement learning (RL have been suggested as algorithmic realizations of goal-directed and habitual action strategies. Model-based RL is more flexible than model-free but requires sophisticated calculations using a learnt model of the world. This has led model-based RL to be identified with slow, deliberative processing, and model-free RL with fast, automatic processing. In support of this distinction, it has recently been shown that model-based reasoning is impaired by placing subjects under cognitive load--a hallmark of non-automaticity. Here, using the same task, we show that cognitive load does not impair model-based reasoning if subjects receive prior training on the task. This finding is replicated across two studies and a variety of analysis methods. Thus, task familiarity permits use of model-based reasoning in parallel with other cognitive demands. The ability to deploy model-based reasoning in an automatic, parallelizable fashion has widespread theoretical implications, particularly for the learning and execution of complex behaviors. It also suggests a range of important failure modes in psychiatric disorders.

    Radiation Protection Programmes are being considered the best way to promote safety culture and to spread and propagate European basic safety standards. It is widely accepted that training is an important tool to upgrade competence for radiation exposed workers. The Spanish Radiation Protection Education and Training Programmes provide a solid and integrated educational model, which takes into account the variety of applied fields, the different levels of responsibilities, the technological and methodological advances, as well as the international tendencies. The needs for a specialised training on Radiation Protection (RP) for exposed workers appears into the Spanish regulation in 1964. National initial training programmes are well established since 1972. Individual certifications, based on personal licences are required for exposed workers. The Spanish regulation also includes continuous and on the job RP training. The educational programmes are being continuously updating and improving. CIEMAT plays an important role in RP Spanish training, improving and modifying the previous RP courses and developing new programmes in order to complete the RP training levels. To achieve Radiation Protection objectives, new technological media for educational methods and material are taking into account. Nevertheless, Spanish RP education and training model has to be improved in some aspects. The purpose of this paper is to analyse the situation and the future needs to be considered in order to complete the RP training processes

    This part treats especially the question of the training in radiation protection. The electro nuclear sector has given an ALARA principle culture and succeeded to sensitize each level of hierarchy, but for small industry, the research and the medical world the same method appears more difficult to use. It seems better to reinforce the importance of the competent person and to include a training in radiation protection on the initial formation in numerous professional categories. (N.C.)

  3. Training in radiological protection for nuclear programmes

    International Nuclear Information System (INIS)

    1975-01-01

    Many Member States are developing or already have developed their own national training programmes. The IAEA is actively involved in promoting training in radiological protection for nuclear programmes. The various types of training are fully discussed, with suggested curricula. An earlier report was published as Technical Reports Series No.31 in 1964. In 1973, new and additional information was received from Member States which is reflected in the present report. Training programmes are classified, according to those requiring training: specialists; persons whose work is closely related to radiological protection (administrators, public health officers and industrial health personnel, safety inspectors and engineers in nuclear installations, public service personnel); persons working with radiation; and the general public. Forms, scope and duration of training are discussed. Different types of training programmes are currently required for training of medical doctors (those providing medical surveillance for radiation workers and others dealing with public health aspects of radiation hazards), for technical supervisors, radiologists, and qualified workers in nuclear medicine, technological staff, administrators, persons working with radiation, and public service personnel. Standard curricula and desirable experiments and exercises are discussed. The organization of training together with the facilities, equipment and teaching staff required are considered, as is follow-up training. Annexes 1 to 4 give examples of training curricula and training courses available in various countries, a suggested syllabus for training of technical supervisors, and a bibliography consisting of 210 references dealing with general topics, nuclear radiation physics, radiochemistry and radiation chemistry, radiation biology and biophysics, dosimetry and health physics and radiation protection, medical aspects and toxicology, and environmental aspects

    We hypothesized that novices will perform better in the operating room after simulator training to automaticity compared with traditional proficiency based training (current standard training paradigm). Simulator-acquired skill translates to the operating room, but the skill transfer is incomplete. Secondary task metrics reflect the ability of trainees to multitask (automaticity) and may improve performance assessment on simulators and skill transfer by indicating when learning is complete. Novices (N = 30) were enrolled in an IRB-approved, blinded, randomized, controlled trial. Participants were randomized into an intervention (n = 20) and a control (n = 10) group. The intervention group practiced on the FLS suturing task until they achieved expert levels of time and errors (proficiency), were tested on a live porcine fundoplication model, continued simulator training until they achieved expert levels on a visual spatial secondary task (automaticity) and were retested on the operating room (OR) model. The control group participated only during testing sessions. Performance scores were compared within and between groups during testing sessions. : Intervention group participants achieved proficiency after 54 ± 14 and automaticity after additional 109 ± 57 repetitions. Participants achieved better scores in the OR after automaticity training [345 (range, 0-537)] compared with after proficiency-based training [220 (range, 0-452; P training to automaticity takes more time but is superior to proficiency-based training, as it leads to improved skill acquisition and transfer. Secondary task metrics that reflect trainee automaticity should be implemented during simulator training to improve learning and skill transfer.

    In compliance with the current laws, radiation protection (RP) training is required during the formative programs of certain Health Sciences specialties. Laws entrust to official bodies in specialized training the adoption of necessary measures to coordinate and ensure a correct implementation. The aim of this study is to describe Community of Madrid experience in RP training to specialists during their formative programs, and to determine the number of residents trained and analyze their satisfaction level with the training. A descriptive cross-sectional study was performed, including all training specialists from the Community of Madrid during the 2007-2011 period. We determined the number of residents trained per year and we evaluated their satisfaction level with the training through a survey. A total of 55 training courses were carried out and 5820 residents have been trained during the 2007-2011 period. the student satisfaction level with the training has increased gradually from 6.1 points in 2007 to 7.0 points in 2011. The development of the RP formative program for residents in the Community of Madrid has meant the start up o the necessary official mechanisms to ensure the quality and adequacy of training in this area, covering the formative needs of the collective.

    Radiation Protection assumes special significance with increasing use of radioactive materials and processes. Scientific and industrial organisations dealing with radioactive materials have prime responsibility of ensuring effective control of all activities which may lead to radiation exposure. Training of all the persons involved in the work associated with radioactivity is absolutely necessary to develop radiation protection skill, radiation measurement proficiency and special precautions to be taken in abnormal situations. NPCIL having responsibility for design, construction, operation and de-commissioning of nuclear power plants, employs about 10,000 workers on several project/station sites all over the country. NPCIL has developed a good training system to accurately control the exposure of workers to radiation. This paper covers the system and other relevant details of radiation protection training organised by NPCIL. (author)

    Several potential problems have been detected in the safety aspects for the practice of interventional radiology procedures: a) An important increase in the number cases and their complexity and the corresponding increase of installations and specialists involved; b) New X ray systems more sophisticated, with advanced operational possibilities, requiring special skills in the operators to obtain the expected benefits;c) New medical specialists arriving to the interventional arena to profit the benefits of the interventional techniques without previous experience in radiation protection. For that reason, education and training is one of the basic areas in any optimisation programme in radiation protection (RP). the medical field and especially interventional radiology requires actions to promote and to profit the benefit of the new emerging technologies for training (Internet, electronic books, etc). The EC has recently sponsored the MARTIR programme (Multimedia and Audio-visual Radiation Protection Training in Interventional Radiology) with the production of two videos on basic aspects of RP and quality control and one interactive CD-ROM to allow tailored individual training programmes. those educational tools are being distributed cost free in the main European languages. To go ahead with these actions, the EC has decided to promote during 2002, a forum with the main Medical European Societies involved in these interventional procedures. (Author)

    The meeting reported in these proceedings was organized to discuss the specific problems of providing information and training on radiation protection to workers exposed to radiation, intervention staff and workers likely to be affected by an activity involving ionizing radiation. Particular emphasis was placed on the need to harmonize basic training on radiation protection in the context of 1992. It seemed advisable for technical training on radiation protection to be introduced into secondary education. To this end, the Commission was asked to draw up a guide for apprentices and students. In view of the growing diversification of activities involving the use of radioactive substances, the Commission was called upon to intensify its efforts in order to ensure that relevant information and training was provided in all firms to workers exposed to ionizing radiation, and to produce guides for specific categories of workers, such as those responsible for the transport of radioactive materials or those likely to be involved in organizing measures in the event of a radiological emergency

    An approach to use the available agricultural parcel information to automatically select training samples for crop classification is investigated. Previous research addressed the multi-evidence crop classification approach using an ensemble classifier. This first produced confidence measures using...... three Multi-Layer Perceptron (MLP) neural networks trained separately with spectral, texture and vegetation indices; classification labels were then assigned based on Endorsement Theory. The present study proposes an approach to feed this ensemble classifier with automatically selected training samples...... approach is named as ECRA (Ensemble based Cluster Refinement Approach). ECRA first automatically removes mislabeled samples and then selects the refined training samples in an iterative training-reclassification scheme. Mislabel removal is based on the expectation that mislabels in each class will be far...

    A new generation of automatic train control systems is currently under development in the commuter-rail transit industry. These systems will utilize radio communication between wayside control computers and trains in order to provide high precision train control beyond the capability of today's automatic systems. The Bay Area Rapid Transit (BART) system is developing such a modern control system in collaboration with Harmon Industries. This system, called the Advanced Automatic Train Control (AATC) system, will allow for precision train locating and control, and will facilitate coordination of the trajectories of multiple trains. This system will be capable of running trains more closely together and decreasing the time a train requires to traverse the system, while simultaneously operating with a more modest traction power infrastructure, and providing a smoother, more comfortable ride to commuters. The authors have collaborated with BART to develop a simulator of the AATC system and the traction power system, and they have utilized this simulator as a testbed for the development of advanced train control techniques. Several train control algorithms, including one employing a neural network for train voltage prediction, have been developed and tested in the simulator. Smoother train trajectories, reduced power infrastructure requirements, and reduced energy consumption have been demonstrated. Improved service reliability is also expected to result.

    The development of a common European radiation protection and safety culture and, based on that, the mutual recognition of radiation protection courses and the acquired competencies of radiation protection experts (RPE) and officers (RPO) is becoming a real need. The ENETRAP project ('European Network for Education and Training in RAdiological Protection') aims at bringing together different ideas and approaches of education and training (E and T) in radiological protection (RP) in order to better integrate and harmonise national E and T activities on a European level. The project started in April 2005. 10 partners are involved in ENETRAP: SCK-CEN (coordinator), CEA-INSTN, FZK-FTU, BfS, ENEA, NRG, CIEMAT, HPA-RPD, UJF and UHI-NHC. These partners have years of experience with established E and T programmes and play an important role in the development of specific techniques such as e-learning or On-the-Job Training (OJT) related to RP. As a result of their fundamental scientific research, collaboration with industry and practical experience, the partners have a solid scientific knowledge of all aspects of RP and are ideally placed to transfer the know-how and estimate the needs in this field. The ENETRAP project aims at establishing a sustainable E and T infrastructure for RP as an essential component to combat the perceived decline in expertise and to ensure the continuation of the high level of RP knowledge. The main objectives of the ENETRAP project are (1) to better integrate existing E and T activities in the RP infrastructure of the European countries in order to combat the decline in both student numbers and teaching institutions, (2) to develop more harmonised approaches for E and T in RP in Europe, (3) to better integrate the national resources and capacities for E and T and (4) to provide the necessary competence and expertise for the continued safe use of radiation in industry, medicine and research. Any such infrastructure must ensure that provision is

    Tractography is the standard tool for automatic delineation of white matter tracts from diffusion weighted images. However, the output of tractography often requires post-processing to remove false positives and ensure a robust delineation of the studied tract, and this demands expert prior knowledge. Here we demonstrate how such prior knowledge, or indeed any prior spatial information, can be automatically incorporated into a shortest-path tractography approach to produce more robust results. We describe how such a prior can be automatically generated (learned) from a population, and we demonstrate that our framework also retains support for conventional interactive constraints such as waypoint regions. We apply our approach to the open access, high quality Human Connectome Project data, as well as a dataset acquired on a typical clinical scanner. Our results show that the use of a learned prior substantially increases the overlap of tractography output with a reference atlas on both populations, and this is confirmed by visual inspection. Furthermore, we demonstrate how a prior learned on the high quality dataset significantly increases the overlap with the reference for the more typical yet lower quality data acquired on a clinical scanner. We hope that such automatic incorporation of prior knowledge and the obviation of expert interactive tract delineation on every subject, will improve the feasibility of large clinical tractography studies.

    A drive train for an electric vehicle includes a traction battery, a power drive circuit, a main contactor for connecting and disconnecting the traction battery and the power drive circuit, a voltage detector across contacts of the main contactor, and a controller for controlling the main contactor to prevent movement of its contacts to the closed position when the voltage across the contacts exceeds a predetermined threshold, to thereby protect the contacts of the contactor. The power drive circuit includes an electric traction motor and a DC-to-AC inverter with a capacitive input filter. The controller also inhibits the power drive circuit from driving the motor and thereby discharging the input capacitor if the contacts are inadvertently opened during motoring. A precharging contactor is controlled to charge the input filter capacitor prior to closing the main contactor to further protect the contacts of the main contactor.

    Full Text Available Train operation is a complex nonlinear process; it is difficult to establish accurate mathematical model. In this paper, we design ATO speed controller based on the input and output data of the train operation. The method combines multimodeling with predictive functional control according to complicated nonlinear characteristics of the train operation. Firstly, we cluster the data sample by using fuzzy-c means algorithm. Secondly, we identify parameter of cluster model by using recursive least square algorithm with forgetting factor and then establish the local set of models of the process of train operation. Then at each sample time, we can obtain the global predictive model about the system based on the weighted indicators by designing a kind of weighting algorithm with error compensation. Thus, the predictive functional controller is designed to control the speed of the train. Finally, the simulation results demonstrate the effectiveness of the proposed algorithm.

    IBM Watson is a cognitive computing system capable of question answering in natural languages. It is believed that IBM Watson can understand large corpora and answer relevant questions more effectively than any other question-answering system currently available. To unleash the full power of Watson, however, we need to train its instance with a large number of well-prepared question-answer pairs. Obviously, manually generating such pairs in a large quantity is prohibitively time consuming and...

  10. Comparison of Radiation Protection Training in European Countries

    2001-01-01

    Full text: Practice and implementation of radiation protection in European countries and in majority of other countries all over the world relies on common principles and recommendations established by international organisations. These principles and recommendations were incorporated in national legislation ensuring similar and compatible standards of protection for occupationally exposed workers and members of the public. One of the basic requirements derived from international recommendations is also formal request for training of occupationally exposed workers. The final goals of the training are defined only indirectly through standards of safety and protection. Therefore national regulation regarding radiation protection training in particular country is a result of general approach to education and training, historical circumstances, influence and importance of nuclear technology and other factors influencing health protection and national well-being in general. The result is variety of national regulations ranging from very stringent and detailed to rather general and flexible. Nevertheless, results of implemented training do not differ sufficiently to significantly affect achieved standards of radiation protection. According to available information European countries implement radiation protection training in dissimilar ways. Institutions and organisations involved, as well as form and duration of training varies from country to country. Therefore, it is not possible to determine common rules just by reviewing radiation protection training in different countries. It is the intention of this contribution to analyse and discuss available information regarding radiation protection training and point out the necessity of international co-operation in this field, especially in the sense of the future trends.

    Diabetic macular edema (DME) is a common vision threatening complication of diabetic retinopathy which can be assessed by detecting exudates (a type of bright lesion) in fundus images. In this work, two new methods for the detection of exudates are presented which do not use a supervised learning step and therefore do not require ground-truthed lesion training sets which are time consuming to create, difficult to obtain, and prone to human error. We introduce a new dataset of fundus images from various ethnic groups and levels of DME which we have made publicly available. We evaluate our algorithm with this dataset and compare our results with two recent exudate segmentation algorithms. In all of our tests, our algorithms perform better or comparable with an order of magnitude reduction in computational time.

  12. An Automatic Identification Procedure to Promote the use of FES-Cycling Training for Hemiparetic Patients

    Directory of Open Access Journals (Sweden)

    Emilia Ambrosini

    2014-01-01

    Full Text Available Cycling induced by Functional Electrical Stimulation (FES training currently requires a manual setting of different parameters, which is a time-consuming and scarcely repeatable procedure. We proposed an automatic procedure for setting session-specific parameters optimized for hemiparetic patients. This procedure consisted of the identification of the stimulation strategy as the angular ranges during which FES drove the motion, the comparison between the identified strategy and the physiological muscular activation strategy, and the setting of the pulse amplitude and duration of each stimulated muscle. Preliminary trials on 10 healthy volunteers helped define the procedure. Feasibility tests on 8 hemiparetic patients (5 stroke, 3 traumatic brain injury were performed. The procedure maximized the motor output within the tolerance constraint, identified a biomimetic strategy in 6 patients, and always lasted less than 5 minutes. Its reasonable duration and automatic nature make the procedure usable at the beginning of every training session, potentially enhancing the performance of FES-cycling training.

    Full text: A sustainable Education and Training (E.T.) infrastructure for Radiation Protection is an essential component to combat the decline in expertise and to ensure the continuation of the high level of radiation protection knowledge in the future. Such infrastructure has to be built in such a way that both the initial training (Education) and the unceasing maintenance of the level of competencies (referred to as 'Training') are available. The E.N.E.T.R.A.P. project intends to develop the E.T. infrastructure mentioned. To achieve the aims of the different tasks and activities, the work programme for the E.N.E.T.R.A.P. Network is divided in eight work packages developed by 11 partners: Each partner will assume responsibility for the W.P.s. C.I.E.M.A.T. is involved in the W.P.-5 'New concepts and new tools for an E.R.P.C.'. The tasks of the W.P.-5 are focussed in the investigation of the electronic tools used in R.P. training and education. This paper presents the first results of this working group. The first task is an approach to the development and usage of learning resources. A review on the e-learning methodologies, the present state of art and its evolution, are being carried out. Results will be used to select the best way to host learning activities in the framework of the E.N.E.T.R.A.P. project. Another important task is to identify, analyse and evaluate the Open and Distance learning tools and material existing for train ing in Radiation Protection. A review on the evolutions, approaches and methodologies aiming to provide education and training in radiation protection, will be carried out. The results of this task will be a summary of links referred to the most interesting R.P. e-learning. Finally, taking in account the previous results a pilot R.P. module of E.R.P.C. should be prepared. (authors)

    Prior to the accident at Three Mile Island, the radiological control training was provided by the health physics and the chemistry departments. The programs that required the input from the health physics department were the Operations Training and the General Employee Training Programs, which were formally organized and presented radiological controls practices as part of the course objectives. The operations training section periodically requested the health physics department management to provide a radiological portion to their operator qualification or operations requalification class. After the accident in 1979, the General Employee Training Program administration was taken over by the operation training department where it underwent changes with a dedicated effort. The Operations Training Program also underwent a change as well as the Radiological Control Technician Training Program. Each group now has a specialty program designed for their specific needs. These programs have been designed using the Institute of Nuclear Power Operations and regulator guidelines

    In Hungary, radiation protection training for radiation workers has been introduced in very early, just following the publication of the ICRP recommendation No. 26. Before that, in some of the institutions, radiation protection training was recommended for technicians and medical doctors working in nuclear medicine, X-ray diagnostic radiology and radiation therapy, as well as in some of industrial applications, but not on regular way. Since 1988, radiation protection training regulated by the Ministry of Health and required for all of the workers in radiation workplaces licensed by the authority the State Public Health and Medical Officers Service (SPHAMOS). Decree No. 16/2000. (VI. 8.) EuM of the Minister of Health on the enforcement of Clauses of the Nuclear Law 116/1996 regulates the radiation protection training of Radiation Workers (RW). Annex 4 of Decree sees radiation protection training and in-service training: Persons performing conducted work in the field of the use of the nuclear energy and any other work within legal relationship shall be educated in training and in-service training at an interval of 5 years. Three levels of the training introduced; basic, extended and comprehensive, based on radiation risk related to the given job. Several institutions are involved in performing radiation protection training, such universities, scientific institutions, Regional Radiological Health Centers (RRHC) of SPHAMOS, private enterprises etc. All training course material is subject to accreditation. Most of the faculties of the universities involved in training of natural sciences and engineering provide subjects on the fundamentals of dosimetry, radiobiology and radiation protection within the courses of physics, biophysics, chemistry, biology, ecology etc. These courses take 5-10 contact hours per week on average. The members of the Hungarian Committee of EUTERP Platform summarize their broad experience collected in the past 20 year. (author)

    2008-07-01

    Time-related capture areas are usually delineated using the backward particle tracking method, releasing circles of equally spaced particles around each well. In this way, an accurate delineation often requires both a very high number of particles and a manual capture zone encirclement. The aim of this work was to propose an Automatic Protection Area (APA) delineation algorithm, which can be coupled with any model of flow and particle tracking. The computational time is here reduced, thanks to the use of a limited number of nonequally spaced particles. The particle starting positions are determined coupling forward particle tracking from the stagnation point, and backward particle tracking from the pumping well. The pathlines are postprocessed for a completely automatic delineation of closed perimeters of time-related capture zones. The APA algorithm was tested for a two-dimensional geometry, in homogeneous and nonhomogeneous aquifers, steady state flow conditions, single and multiple wells. Results show that the APA algorithm is robust and able to automatically and accurately reconstruct protection areas with a very small number of particles, also in complex scenarios.

  19. Design And Development Of An Automatic Single Phase Protective Device Using Ssr

    Full Text Available Since the discovery of energy safety has been a paramount subject matter. This we can see in todays electrical systems where protective devices such as fuse and circuit breakers are used to prevent fire hazards resulting from overload overvoltage and short circuits. However with all the revolution in technology these options may be considered less smart since the fuse made with wire strands calculated for specific current capacity faults permanently when the specified current rating is exceeded. While the circuit breaker which is made up of mechanical switch fails as a result of carbon forming and the wearing away of the contacts because of arcing. As a means of improvement this paper presents the design and development of an automatic single phase protective device using solid state relay SSR. This study is to ensure automatic cut off from power supply in cases of overvoltage above 240 V AC or when overload and short circuit current above 8amps is detected without permanent damage of a fuse placed along current path. Also the design will ensure that there is an automatic close circuit whenever the trigger switch is momentary switch is closed. The system is achieved via the use of PIC micro-controller current sensor and other discrete components. The system is tested and works well inhibiting the frequent faulting of fuses. It also helps to prevent hazard as a result of overvoltage overload and short circuit and ensures a close circuit when the trigger switch is closed.

  20. Using computer-based training to facilitate radiation protection review

    In a national laboratory setting, it is necessary to provide radiation protection overview and training to diverse parts of the laboratory population. This includes employees at research reactors, accelerators, waste facilities, radiochemical isotope processing, and analytical laboratories, among others. In addition, our own radiation protection and monitoring staffs must be trained. To assist in the implementation of this full range of training, ORNL has purchased prepackaged computer-based training in health physics and technical mathematics with training modules that can be selected from many topics. By selection of specific modules, appropriate radiation protection review packages can be determined to meet many individual program needs. Because our radiation protection personnel must have some previous radiation protection experience or the equivalent of an associate's degree in radiation protection for entry level, the computer-based training will serve primarily as review of major principles. Others may need very specific prior training to make the computer-based training effective in their work situations. 4 refs

    The International Community has established a dose limitation system to control the risks due to the ionizing radiation pacific use. The education and training of the occupational exposed workers is necessary to achieve the objectives of this dose limitation system.The second largest contribution to exposures of the individuals worldwide after natural background radiation, comes from medical radiation procedures. For this reason, the radiation protection training of medical workers is essential. In the particular autonomous region of Andalusia, most medical radiation procedures comes from the Public Health Service. Therefore, Andalusia Healthy Service maintains a radiation protection training plan for their occupational exposed workers. This training plan includes: training of the radioactive facilities supervisors and operators in both nuclear medicine and radiotherapy areas; training for medical radiodiagnosis facility management; quality assurance in medical diagnosis and therapy; and update on radiation protection. The training plan is performed with theoretical and practical course homologated by the Spanish Nuclear Safety Council. These courses cover four basic fields related to radiation: Physics, Radiobiology, Radiation Protection and Legislation. These courses have been organised by the Andalusia Healthy System since 1993. A total of 722 medical workers have been trained for radiation protection. Therefore, optimum conditions for the safe and correct use of ionizing radiation have been provided to these workers.

    Abacus-based mental calculation (AMC) is a unique strategy for arithmetic that is based on the mental abacus. AMC experts can solve calculation problems with extraordinarily fast speed and high accuracy. Previous studies have demonstrated that abacus experts showed superior performance and special neural correlates during numerical tasks. However, most of those studies focused on the perception and cognition of Arabic numbers. It remains unclear how the abacus numbers were perceived. By applying a similar enumeration Stroop task, in which participants are presented with a visual display containing two abacus numbers and asked to compare the numerosity of beads that consisted of the abacus number, in the present study we investigated the automatic processing of the numerical value of abacus numbers in abacus-trained children. The results demonstrated a significant congruity effect in the numerosity comparison task for abacus-trained children, in both reaction time and error rate analysis. These results suggested that the numerical value of abacus numbers was perceived automatically by the abacus-trained children after long-term training.

    In the 2010 Nuclear Security Summit, there was a movement to strengthen the international effort to protect nuclear materials and other radioactive materials against malicious acts. By recognizing the importance of human resource development and training in nuclear security, the Republic of Korea (ROK) pledged to establish an international training center on nuclear security. Consequently, the International Nuclear Security Academy (INSA) was established in Korea Institute of Nuclear Nonproliferation and Control (KINAC) in February 2014. The INSA contributes to meet not only the domestic needs but also international needs for nuclear nonproliferation and security training. Meanwhile, since 2012, KINAC is the only physical protection training provider for nuclear facility operators designated by Nuclear Safety and Security Commission (NSSC). In this paper, we are going to introduce our four-year physical protection training activities for nuclear facility operators and describe X-Ray Web-Based Training (WBT) program to be used for physical protection training of nuclear security guards. KINAC/INSA, as the only physical protection training provider for nuclear facility operators designated by NSSC, puts emphasis on delivering effective and high-quality training program. We, open a door for nuclear facility operators to share lessons they learned. Considering the survey result on the training program, we will apply X-Ray WBT program for training of nuclear security guards. Efforts to improve training quality will be continued.

    As stroke being one of the most leading causes of death worldwide, even stroke survivors have to suffer from dysfunctions of limb controls and inabilities of speech or vision. Cognitive neuroscientists have found various forms of automatic behaviours in healthy people, which generally cover motor components of upper limbs and are essential for coordination and mobility relevant activities. Meanwhile, the robot-assisted therapy and functional electrical stimulation have become prominent rehabilitation techniques for patients' rehabilitation after stroke. With the integration of robot-aided therapeutic systems and the functional electrical stimulation, the on-line 'automatic pilot' training of the visual inspired stimulation for upper limbs can offer a feasible treatment for patients after stroke to recover motor performance.

    2016-01-01

    Full Text Available This paper presents a novel method to solve the initial lightning breakdown current by combing ATP and MATLAB simulation software effectively, with the aims to evaluate the lightning protection performance of transmission line. Firstly, the executable ATP simulation model is generated automatically according to the required information such as power source parameters, tower parameters, overhead line parameters, grounding resistance and lightning current parameters, etc. through an interface program coded by MATLAB. Then, the data are extracted from the generated LIS files which can be obtained by executing the ATP simulation model, the occurrence of transmission lie breakdown can be determined by the relative data in LIS file. The lightning current amplitude should be reduced when the breakdown occurs, and vice the verse. Thus the initial lightning breakdown current of a transmission line with given parameters can be determined accurately by continuously changing the lightning current amplitude, which is realized by a loop computing algorithm that is coded by MATLAB software. The method proposed in this paper can generate the ATP simulation program automatically, and facilitates the lightning protection performance assessment of transmission line.

    This set of guidelines applies to radiation protection training programs for all Department of Energy (DOE) contractors, subcontractors, and visitors to DOE contractor facilities. It is to be used as a self-evaluation tool by DOE contractors as they develop and evaluate their training programs. This document is based on good practice guidelines used by a variety of different facilities both within and outside of the DOE contractor system. Good practices are not requirements; they are guidelines that contractors should use as they develop and conduct training programs. The applicability of the contents of the Guide to Good Practice in Radiation Protection Training depends upon each DOE facility's scope and need for radiation safety training. Although the focus of this document is radiation protection training, it is important that the process by which training is developed and implemented be discussed. Therefore, the first section presents guidelines for performance-based training and ideas to be considered regarding the structure and documentation of the training function

    In order to realize radiation protection reliably mandatory protection goals have to be defined. These goals were formulated using the fundamentals of radiation protection and are described by the terms ''justification'', ''dose limitation'' and ''dose reduction and dose minimization''. While there is consensus within Europe with respect to the protection goals the implementation of one of the main components, the radiation protection education and training is regulated in very different ways in European countries. At the same time the necessity of comparable certificates is growing, which will be enhanced by the amendment of the EU BSS (basic safety standards). The authors recommend to study the different approaches to learn from each other.

    Education and training are an important tool to promote safety culture and to upgrade competence. In this sense, Radiation Protection (R.P.) training programmes are a major challenge in order to achieve occupational, public and environmental radiation protection in all applied fields of ionising radiation.The Spanish R.P. Education and Training system provides a solid and integrated educational model. The needs for a specialized training on R.P. for exposed workers appears into the Spanish regulation in 1964. Since then, a wide variety of R.P. initial, continuous and on the job training courses has been carried out, taking into account the diverse applied fields, the different levels of responsibilities, the technological and methodological advances, as well as the international trends. C.I.E.M.A.T., through the R.P. training Unit, has been organizing and developing most of the R.P. training in Spain since 1964, becoming a reference centre. The educational programmes are being continuously updating and improving in order to complete and adapt all R.P. training levels. Initial training, long-life training, updating or upgrading training, as well as other innovative courses related with R.P. are being offered by C.I.E.M.A.T. each year. Another important aspect of R.P. is the information and training to stake holders. C.I.E.M.A. T. is also working in this sense. The purpose of this paper is to analyse the evolution of R.P. training processes since 1964 in Spain, in order to conclude which are the future trends and the changes required to adapt the Spanish R.P. Education and Training system to the current needs and upcoming scene. (authors)

    2017-01-01

    Full Text Available An urban rail transit (URT system is operated according to relatively punctual schedule, which is one of the most important constraints for a URT passenger’s travel. Thus, it is the key to estimate passengers’ train choices based on which passenger route choices as well as flow distribution on the URT network can be deduced. In this paper we propose a methodology that can estimate individual passenger’s train choices with real timetable and automatic fare collection (AFC data. First, we formulate the addressed problem using Manski’s paradigm on modelling choice. Then, an integrated framework for estimating individual passenger’s train choices is developed through a data-driven approach. The approach links each passenger trip to the most feasible train itinerary. Initial case study on Shanghai metro shows that the proposed approach works well and can be further used for deducing other important operational indicators like route choices, passenger flows on section, load factor of train, and so forth.

    This study aimed to develop a computer game for machine vision integrated rehabilitation training system. The main function of the system is to allow users to conduct hand grasp-and-place movement through machine vision integration. Images are captured by a double-CCD camera, and then positioned on a large screen. After defining the right, left, upper, and lower boundaries of the captured images, an automatic spatial positioning technique is employed to obtain their correlation functions, and lookup tables are defined for cameras. This system can provide rehabilitation courses and games that allow users to exercise grasp-and-place movements, in order to improve their upper limb movement control, trigger trunk control, and balance training.

    Iberdrola Ingenieria y Consultoria (Iberinco) has developed some computer applications based in New Technologies, Virtual Reality and Multimedia, with the aim to optimise the formation and training of professionally exposed workers as well as to inform the public. The use of the new technologies could be an important help for the workers training. Virtual Reality Projects developed by Iberinco are: a) CIPRES: Interactive Calculations of Radiological Protection in a Simulation Environmental and, b) ACEWO: Workers Control Access to Nuclear Power Plants, virtual Reality could be directly applicable to several aspects related with Radiological Protection Training, for example. An application that workers could used to learn the main aspects of Radiological Protection related with: a) Physical concepts, b) Regulations, c) Use of protective clothing, d) Access into and exit out controlled areas, e) ALARA criterion. An examples is the project ACEWO. A training program based on Virtual Reality systems with simulations of procedures in which the operators could receive high doses. In this way, the operation time and dose could be minimised according to the ALARA criterion owing to the ability of repeating the exercise, or the work, as many times as be necessary, like project CIPRES. Iberinco has been developed an educational CD multimedia on nuclear energy and the protection measures foreseen in the emergency plans for the Spanish Civil Protection Agency, with the aim of being distributed to all the schools placed near a nuclear power plant.

    2017-01-01

    Full Text Available The article describes solution path of the problem of information automatic copying from web-sites in the Internet, which is implemented using parsing techniques based on regular expressions or function libraries. To protecting against this type of information security threat, it is proposed to dynamically generate and periodically change the object model of the HTML document when generated and sent to the browser. These changes should affect the values of the identifying tag attributes and the structure of the object model tree. As attribute values it is offered to use character sets of limited length obtained as a result of random numbers hashing; change of the structure of the object model should be done by adding of additional tags at the corresponding levels of the hierarchy of the tree representing it. The simultaneous application of these methods excludes the possibility of algorithm compile for the necessary information extraction in the overall structure of the web page.

    Radiation Protection should be included in the programme of studies necessary to confer a bachelor's degree in Medicine, according to the Directive 97/43 Euratom on medical exposures and the Report RP116 published by the European commission on Education and Training in radiation protection for medical exposures. To analyse the present training programmes in radiation protection at the Medical School in different Spanish Universities. The syllabus and the contents of the subjects including radiation protection issues in 27 Spanish Schools of Medicine have been revised. Radiation protection subjects are obligatory at present, only at the Schools of Medicine from Cantabria and Malaga. There is a group of Schools of Medicine where radiation protection is an optional matter with an extension of 4,5 credits (45 hours). It also exists some topics in radiation protection in subjects dealing with Medical Physics and General Radiology (with a range value from 1 to 10 hours), in 10 Schools of Medicine. A wide dispersion among the contents of different subjects and the hours of training allocated by the different School are found. It should be useful the harmonization of the programmes. (Author)

    Automatic detection of adverse drug reaction (ADR) mentions from text has recently received significant interest in pharmacovigilance research. Current research focuses on various sources of text-based information, including social media-where enormous amounts of user posted data is available, which have the potential for use in pharmacovigilance if collected and filtered accurately. The aims of this study are: (i) to explore natural language processing (NLP) approaches for generating useful features from text, and utilizing them in optimized machine learning algorithms for automatic classification of ADR assertive text segments; (ii) to present two data sets that we prepared for the task of ADR detection from user posted internet data; and (iii) to investigate if combining training data from distinct corpora can improve automatic classification accuracies. One of our three data sets contains annotated sentences from clinical reports, and the two other data sets, built in-house, consist of annotated posts from social media. Our text classification approach relies on generating a large set of features, representing semantic properties (e.g., sentiment, polarity, and topic), from short text nuggets. Importantly, using our expanded feature sets, we combine training data from different corpora in attempts to boost classification accuracies. Our feature-rich classification approach performs significantly better than previously published approaches with ADR class F-scores of 0.812 (previously reported best: 0.770), 0.538 and 0.678 for the three data sets. Combining training data from multiple compatible corpora further improves the ADR F-scores for the in-house data sets to 0.597 (improvement of 5.9 units) and 0.704 (improvement of 2.6 units) respectively. Our research results indicate that using advanced NLP techniques for generating information rich features from text can significantly improve classification accuracies over existing benchmarks.

    The information and training of workers in radiation protection should be given priority as a means of preventing the hazards of ionizing radiation. In view of the importance of the human factor in accident prevention, it would be inconsistent not to place more emphasis on the training of workers exposed at work. Training staff should not only have technical knowledge in the field of radiation protection, but should also be properly trained in how to teach adults. Teaching tools should be developed at Community level to make the job of trainers, occupational physicians and radiation protection experts easier. Regularly updated documents should supply the basic information for radiation protection, and not neglect areas of uncertainty, or problems which the experts are still debating. These documents must include the special information referred to in the Directive of 15 July 1980, in particular: . the reasons for limiting the dose for women of child-bearing age and the nature and level of the risks for the embryo and foetus, according to the dose received; . the potential hazards of exceptional exposure. . The information and training of workers should help to improve understanding of occupational risks and not serve as a vehicle for propaganda on the harmlessness of nuclear power. In addition, they should openly recognize the nuclear risks including the difficult problem of low doses, but should not confuse the issue with ambiguous statistics

    Argentina has an extensive background in education and training on Radiation Protection. Since the beginning of the nuclear activity in the country, prominence was given to the aspects related to radiation protection and training of the personnel involved in the use of ionizing radiation. These educative activities have been delivered for more than 50 years, having accumulated an important experience in the field. The Nuclear Regulatory Authority has the statutory obligation to address, among other matters, the control of the aspects of nuclear safety and radiation protection on the whole country, to protect the people of the harmful effects of ionizing radiation resulting from the nuclear activities. This includes the responsibility to develop and enforce the regulations, standards and other requirements, particularly, establishing the requests and promoting activities regarding education and training on radiation protection. Argentina, currently through the Nuclear Regulatory Authority, has performed postgraduate courses on radiation protection and nuclear safety at inter regional and regional level for 28 years without interruption. This important experience has been valued and exploited to form a Regional Center on Education and Training for Latin America and the Caribbean, sponsored by the International Atomic Energy Agency. The Regional Center that in fact has been running in Argentina, trained 404 foreign participants and 327 local participants since 1980, totalizing 731 graduates from our annual post graduate courses. Our commitment is that all the effort made in education and training on radiation protection and nuclear safety contributes to a better use of the benefits of nuclear development. Since 2001 the International Atomic Energy Agency raised the need to develop plans and establish agreements to ensure a long-term sustainability of the education and training programs, allowing a better use of the resources in this area. In order to achieve this goal

    Many nations, Kenya inclusive, have insufficient number of trained personnel to deal with regulatory and technical radiation safety issues. The IAEA Basic safety standards and the 96/29 EURATOM Directive put emphasis on education and training. Both organizations as well as IRPA have been proactive on training and educational issues. The Eastern Africa Association for Radiation Protection (EAARP) in collaboration with some national institutions has also been involved in awareness creation and provision of training and education opportunities for users of radioactive sources as well as the general public on issues related to radiation protection. Experience so far indicates that public demand is high for information and education in this area. In this paper we have identified the educational needs in radiation protection in the region using the Kenyan experience. The paper has also enumerated the available educational and training infrastructures, the human resources, as well as the important stake holders and their roles if a sustainable education and training program were to be developed in the region

    This paper uses a difference-in-differences approach, combined with propensity score matching, to identify the effect of older workers employment protection on French firms' incentives to sponsor training. Between 1987 and 2008, French firms laying off workers aged over 50 had to pay a tax...... to the unemployment insurance system, known as the Delalande tax. In 1999, the measure was subjected to a reform that increased the tax, but only for large firms. We find that this exogenous increase substantially raised firms' incentives to train workers aged 45–49 but had no impact on the training rates among...

    2003-01-01

    Using an Internet Virtual Reality (IVR) technique, a 3-dimensional (3-D) model for the radiation controlled area in a nuclear power plant was developed, and a feasibility study to develop a computational program to estimate radiation dose was performed. For this purpose, a pilot model with a dynamic function and bi-directional communication was developed. This model was enhanced from the existing 3-D single-directional communication. In this pilot model, a plant visitor needs to first pass a series of security checks. If the visitor enters the controlled area and approaches a radiation hazard area, alarms with a warning lamp will be initiated automatically. Throughout the test to connect this model from both domestic and international sites in various time zones, it has proven to perform well. Therefore, this model can be applied to broad fields as radiation protection procedures or radiation protection training with photographic data, and on-line dose assessment programs

    The automation of extracting chemical names from text has significant value to biomedical and life science research. A major barrier in this task is the difficulty of getting a sizable and good quality data to train a reliable entity extraction model. Another difficulty is the selection of informative features of chemical names, since comprehensive domain knowledge on chemistry nomenclature is required. Leveraging random text generation techniques, we explore the idea of automatically creating training sets for the task of chemical name extraction. Assuming the availability of an incomplete list of chemical names, called a dictionary, we are able to generate well-controlled, random, yet realistic chemical-like training documents. We statistically analyze the construction of chemical names based on the incomplete dictionary, and propose a series of new features, without relying on any domain knowledge. Compared to state-of-the-art models learned from manually labeled data and domain knowledge, our solution shows better or comparable results in annotating real-world data with less human effort. Moreover, we report an interesting observation about the language for chemical names. That is, both the structural and semantic components of chemical names follow a Zipfian distribution, which resembles many natural languages.

Panchromatic (1m and multispectral (4m Kompsat-2 images (July 2008 of Karacabey Plain (~100km2, located in Marmara region, are used to evaluate the proposed approach. Due to the characteristic of rich, loamy soils combined with reasonable weather conditions, the Karacabey Plain is one of the most valuable agricultural regions of Turkey. Analyses start with applying an image fusion algorithm on the panchromatic and multispectral image. As a result of this process, 1m spatial resolution colour image is produced. In the next step, the four-band fused (1m image and multispectral (4m image are orthorectified. Next, the fused image (1m is segmented using a popular segmentation method, Mean- Shift. The Mean-Shift is originally a method based on kernel density estimation and it shifts each pixel to the mode of clusters. In the segmentation procedure, three parameters must be defined: (i spatial domain (hs, (ii range domain (hr, and (iii minimum region (MR. In this study, in total, 176 parameter combinations (hs, hr, and MR are tested on a small part of the area (~10km2 to find an optimum segmentation result, and a final parameter combination (hs=18, hr=20, and MR=1000 is determined after evaluating multiple goodness measures. The final segmentation output is then utilized to the classification framework. The classification operation is applied on the four-band multispectral image (4m to minimize the mixed pixel effect. Before the image classification, each segment is overlaid with the bands of the image fused, and several descriptive statistics of each segment are computed for each band. To select the potential homogeneous regions that are eligible for the selection of training samples, a user-defined threshold is applied. After finding those potential regions, the

  12. Guidelines for training and qualification of radiological protection technicians

    International Nuclear Information System (INIS)

    1987-08-01

    These guidelines, used in combination with plant-specific job analysis, provide the framework for a training and qualification program for radiological protection technicians at nuclear power plants. Radiological protection technicians are defined as those individuals, both plant and contractor, who will be engaged in the evaluation of radiological conditions in the nuclear plant and the implementation of the necessary radiological safety measures as they apply to nuclear plant workers and members of the general public. An important aspect of this work is recognizing and handling unusual situations involving radioactivity, including incidents related to degraded core conditions. These guidelines incorporate the results of an industry-wide job analysis and task analysis (JTA) combined with industry operating experience review. However, the industry-wide analyses did not identify all important academic and fundamental knowledge and skills. Further in-depth analysis by subject matter experts produced additional knowledge and skills that were added to these guidelines. All utilities should use these guidelines in conjunction with plant-specific and industry-wide JTA results to develop or validate their radiological protection technician training program. Plant-specific information should be used to establish appropriate training program content. This plant-specific information should reflect unique job duties, equipment, operating experience, and trainee entry-level qualifications. Revisions to these guidelines should be reviewed for applicability and incorporated into the training program using each utility's training system development (TSD) procedures. Plant-specific job analysis and task analysis data is essential to the development of performance-based training programs. These analyses are particularly useful in selecting tasks for training and in developing on-the-job training (OJT), laboratory training, and mock-up training. Qualification programs based on these

    Full Text Available Supervised classification is the commonly used method for extracting ground information from images. However, for supervised classification, the selection and labelling of training samples is an expensive and time-consuming task. Recently, automatic information indexes have achieved satisfactory results for indicating different land-cover classes, which makes it possible to develop an automatic method for labelling the training samples instead of manual interpretation. In this paper, we propose a method for the automatic selection and labelling of training samples for high-resolution image classification. In this way, the initial candidate training samples can be provided by the information indexes and open-source geographical information system (GIS data, referring to the representative land-cover classes: buildings, roads, soil, water, shadow, and vegetation. Several operations are then applied to refine the initial samples, including removing overlaps, removing borders, and semantic constraints. The proposed sampling method is evaluated on a series of high-resolution remote sensing images over urban areas, and is compared to classification with manually labeled training samples. It is found that the proposed method is able to provide and label a large number of reliable samples, and can achieve satisfactory results for different classifiers. In addition, our experiments show that active learning can further enhance the classification performance, as active learning is used to choose the most informative samples from the automatically labeled samples.

    The use of ionizing radiation in biological research has many specific characteristics. A great variety of radioisotopic techniques involve unsealed radioactive sources, and their use not only carries a risk of irradiation, but also a significant risk of contamination. Moreover, a high proportion of researchers are in training and the labor mobility rate is therefore high. Furthermore, most newly incorporated personnel have little or no previous training in radiological protection, since most academic qualifications do not include training in this discipline. In a biological research center, in addition to personnel whose work is directly associated with the radioactive facility (scientific-technical personnel, operators, supervisors), there are also groups of support personnel The use of ionizing radiation in biological research has many specific characteristics.

    A tenet of behavioral education is that interactive training produces superior retention compared with reading. However, this has not often been directly tested and never with practical occupational information in working adults. Adults from diverse occupational backgrounds learned the principles of proper respiratory protection presented (a) in a book, (b) on a computer monitor, (c) through interactive computerized training consisting of textual information and illustrative pictures followed by quizzes and feedback, or (d) passively viewing the information and quizzes in Condition c on a computer monitor. Interactive training produced significantly more correct test answers at immediate posttraining, 1 week, and 2 months. This study demonstrated the superiority of interactive training for teaching occupational safety and health information in working adults.

    Full Text Available Understanding neuronal mechanisms of learned behaviors requires efficient behavioral assays. We designed a high-throughput automatic training system (HATS for olfactory behaviors in head-fixed mice. The hardware and software were constructed to enable automatic training with minimal human intervention. The integrated system was composed of customized 3D-printing supporting components, an odor-delivery unit with fast response, Arduino based hardware-controlling and data-acquisition unit. Furthermore, the customized software was designed to enable automatic training in all training phases, including lick-teaching, shaping and learning. Using HATS, we trained mice to perform delayed non-match to sample (DNMS, delayed paired association (DPA, Go/No-go (GNG, and GNG reversal tasks. These tasks probed cognitive functions including sensory discrimination, working memory, decision making and cognitive flexibility. Mice reached stable levels of performance within several days in the tasks. HATS enabled an experimenter to train eight mice simultaneously, therefore greatly enhanced the experimental efficiency. Combined with causal perturbation and activity recording techniques, HATS can greatly facilitate our understanding of the neural-circuitry mechanisms underlying learned behaviors.

    Recent studies have shown that there is a wide variety of approaches to education and training of the Qualified Expert across the EU. As they stand, such differences are a barrier to the mutual recognition of the Qualified Expert status and, in part, are contributing to a perceived shortage in expertise in radiation protection and safety. The overall aim of ENETRAP is to determine mechanisms that in the longer term will facilitate better integration of education and training activities (with a view to mutual recognition across the EU) and to ensure the ongoing provision of the necessary competence and expertise at the level of the Qualified Expert.

    Deficits in motor movement automaticity in Parkinson's disease (PD), especially during multitasking, are early and consistent hallmarks of cognitive function decline, which increases fall risk and reduces quality of life. This study aimed to test the feasibility and potential efficacy of a wearable sensor-enabled technological platform designed for an in-home music-contingent stepping-in-place (SIP) training program to improve step automaticity during dual-tasking (DT). This was a 4-week prospective intervention pilot study. The intervention uses a sensor system and algorithm that runs off the iPod Touch which calculates step height (SH) in real-time. These measurements were then used to trigger auditory (treatment group, music; control group, radio podcast) playback in real-time through wireless headphones upon maintenance of repeated large amplitude stepping. With small steps or shuffling, auditory playback stops, thus allowing participants to use anticipatory motor control to regain positive feedback. Eleven participants were recruited from an ongoing trial (Trial Number: ISRCTN06023392). Fear of falling (FES-I), general cognitive functioning (MoCA), self-reported freezing of gait (FOG-Q), and DT step automaticity were evaluated. While we found no significant effect of training on FES-I, MoCA, or FOG-Q, we did observe a significant group (music vs podcast) by training interaction in DT step automaticity (Pmusically-contingent SIP training to increase motor automaticity for people living with PD. The training approach described here can be implemented at home to meet the growing demand for self-management of symptoms by patients.

    Proper selection of staff and their special education and training in radiation protection are important factors when assuring faultless man-machine interaction and thereby a reduced likelihood of human factor failure in hazardous practices. University-level institutions can only provide education in the individual partial segments of the multidisciplinary area of radiation protection, whereas the proper practices are learned by graduate personnel on the job, by performing operational tasks at their particular workplace. The scope o expertise of subjects providing radiation protection surveillance and the requirements for their special education and training are outlined. Supervising persons appointed by the radiation source handling licensee to perform a number of operational tasks at the workplace assume a prominent position. Alternatively, systematic supervision at the workplace can be contracted by the licensee from an external body, provided that the latter has acquired appropriate licence from the State Office for Nuclear Safety. The provisions of the Atomic Act and the related implementing regulations with respect to special training and to the examination of professional competence before an expert commission are briefly outlined.

    Radiation protection training for the general employee at the Oak Ridge National Laboratory has undergone a great deal of restructuring in the last two years. The number of personnel totally dedicated to nuclear facilities is less than a fifth of our employees and the percentage of contracted employees who are dedicated radiation workers is much smaller. However, the aging of our facilities and increasing emphasis on environmental control means that everyone needs to understand the basics of radiation protection. In accordance with changing DOE guidelines and internal ORNL policies, greater emphasis has been placed on keeping training focused on current issues, training the total workforce, and requiring some type of testing or feedback mechanism. This report describes efforts to instill respect, but not fear, of radiation in the work environment. Flexible tools are being developed to meet this objective for several diverse general employee populations. Continuing efforts include consideration of computer-based training for retraining, developing additional modules for specialized groups and jobs, and testing/documentation appropriate to each population segment. 6 refs

    Image segmentation is an essential step in quantifying the extent of reduced or absent lung function. The aim of this study is to develop and validate a new tool for automatic segmentation of lungs in ventilation and perfusion SPECT images and compare automatic and manual SPECT lung segmentations with reference computed tomography (CT) volumes. A total of 77 subjects (69 patients with obstructive lung disease, and 8 subjects without apparent perfusion of ventilation loss) performed low-dose CT followed by ventilation/perfusion (V/P) SPECT examination in a hybrid gamma camera system. In the training phase, lung shapes from the 57 anatomical low-dose CT images were used to construct two active shape models (right lung and left lung) which were then used for image segmentation. The algorithm was validated in 20 patients, comparing its results to reference delineation of corresponding CT images, and by comparing automatic segmentation to manual delineations in SPECT images. The Dice coefficient between automatic SPECT delineations and manual SPECT delineations were 0.83 ± 0.04% for the right and 0.82 ± 0.05% for the left lung. There was statistically significant difference between reference volumes from CT and automatic delineations for the right (R = 0.53, p = 0.02) and left lung (R = 0.69, p automatic quantification of wide range of measurements.

    The contribution describes the new measuring and protection system of the VR-1 training reactor. The measuring and protection system upgrade is an integral part of the reactor I and C upgrade. The new measuring and protection system of the VR-1 reactor consists of the operational power measuring and the independent power protection systems. Both systems measure the reactor power and power rate, initiate safety action if safety limits are exceeded and send data (power, power rate, status, etc.) to the reactor control system. The operational power measuring system is a full power range system that receives signal from a fission chamber. The signal is evaluated according to the reactor power either in the pulse or current mode. The current mode utilizes the DC current and Campbell techniques. The new independent power protection system operates in the two highest reactor power decades. It receives signals from a boron chamber and evaluates it in the pulse mode. Both systems are computer based. The operational power measuring and independent power protection systems are diverse - different types and location of chambers, completely different hardware, software algorithms for the power and power rate calculations, software development tools and teems for the software manufacturing.

    The EU Council Directive 97\\/43\\/EURATOM (MED) states that Member States shall ensure that adequate theoretical and practical training is provided for dental practitioners working with ionising radiation; this also includes the provision of continuing education and training programmes, post-qualification. The area of dental radiology is specifically mentioned in this legally binding document. The Department of Medical Physics and Bioengineering, St James\\'s Hospital, Dublin, is particularly interested in the area of radiation protection training and routinely provides educational courses both at national and international levels. A recent review of their dental radiation protection course was undertaken in conjunction with a number of Principal Dental Surgeons within the Health Service Executive in Ireland. The revised course was delivered to over 200 dental staff members at two separate meetings during 2006. The response from attendees was very positive. It is proposed to extend this course to other dental professionals, working both in the Irish private and public health sectors in the future.

It consists of a main server and 3 clients with a software for virtual reality. With this system the trainee could go into the virtual laboratory and handle the radioisotope. In that case he could also experience various accidents such as trivial failure in the experiments, serious hazard, fire, earthquake, etc., which are difficult to suffer in the real laboratory. Hence those who have experienced such a training could come to act rapidly up against any sudden accidents and also the virtual reality system would result decrease in unnecessary radioactive wastes

    The current state and need for radiation protection training in Finland have been surveyed by the Radiation and Nuclear Safety Authority STUK. The survey sought to determine whether the current requirements for radiation protection training had been met, and to promote radiation protection training. Details of the scope and quality of present radiation protection training were requested from all educational institutes and organizations providing radiation protection training. The survey covered both basic and further training, special training of radiation safety officers, and supplementary training. The questionnaire was sent to 77 educational organization units, 66 per cent of which responded. Radiation workers and radiation safety officers were asked about radiation protection knowledge and needs for additional training. The questionnaire was sent to 880 radiation users and 170 radiation safety officers, 70 per cent of whom responded. The survey covered all professional groups and fields of the use of ionizing radiation except nuclear energy. The amount of radiation protection training in basic and further (specialization) training in the same vocational or academic degree varied remarkably by educational organization. The average amounts of radiation protection included in most professional degrees met the requirements. 32 per cent of workers considered their radiation protection training inadequate for their duties, and 48 per cent had completed no supplementary training in radiation protection over the last five years. Nurses working in public sector hospitals and physicians working in health centres had the greatest need for radiation protection training. 78 per cent of radiation workers in industry felt that they had sufficient radiation protection training. Co-operation between educational organizations is necessary to harmonize radiation protection training. Guidance of the Ministry of Education (the competent authority for education) is needed in this

    The CMS ECAL Detector Control System (DCS) features several monitoring mechanisms able to react and perform automatic actions based on pre-defined action matrices. The DCS is capable of early detection of anomalies inside the ECAL and on its off-detector support systems, triggering automatic actions to mitigate the impact of these events and preventing them from escalating to the safety system. The treatment of such events by the DCS allows for a faster recovery process, better understanding of the development of issues, and in most cases, actions with higher granularity than the safety system. This paper presents the details of the DCS automatic action mechanisms, as well as their evolution based on several years of CMS ECAL operations.

    In the Peru, according to the current regulations, people that work with ionizing radiations should have an authorization (individual license), which is granted by the Technical Office of the National Authority that is the technical body of the Instituto Peruano de Energia Nuclear (IPEN) manager of the control of ionizing radiations in the country. The individual license is obtained after the applicant fulfills the requested requirements, as having safety knowledge and radiological protection. Since its founding in 1972, the Centro Superior de Estudios Nucleares (CSEN) of the IPEN has carried out diverse training courses in order to that people can work in a safe way with ionizing radiations in medicine, industry and research, until the year 2013 have been organized 2231 courses that have allowed the training of 26213 people. The courses are organized according to the specific work that is carried out with radiations (medical radio-diagnostic, dental radiology, nuclear medicine, radiotherapy, industrial radiography, nuclear meters, logging while drilling, etc.). In their majority the courses are directed to people that will make use of radiations for first time, but refresher courses are also granted in the topic. The CSEN also carries out the Master degree programs highlighting the Second Professional Specialization in Radiological Protection carried out from the year 2004 with the support of the National University of Engineering. To the present has been carried out 2 programs and there is other being developed. In this work is shown the historical evolution of the radiological protection courses as well as the important thing that they are to work in a safe way in the country. (Author)

    Since its creation in 1967, the Argentine Radiation Protection Society (SAR) promotes all the radiation protection and nuclear safety aspects not only within the scientific, technical and academic areas, but also to general public. To fulfill this objective, SAR organised training and refresher courses, seminars and workshops on RP subjects. During 2002, SAR organised 7 basic and specialized courses regarding the uses of radioactive materials in industrial applications and the course on medical response in radiological accidents, that was attended by Argentine and other Latin American participants. The programmes of the courses are developed in compliance with the legal requirements and also considering specifics needs. In this paper, the characteristics of the courses are enunciated and basic statistics regarding courses and participants are presented. For the 2003 and 2004, SAR foresees the organisation of 18 courses per year and has the capacity to deliver other courses by request. all the courses are delivered in Spanish language. Based on this educational experience SAR consider a priority the inclusion, of a RP module in all the scientific graduate programmes to generate awareness on the importance of RP. Taking into account the migration of professionals to Europe and North America and the Globalization, SAR advocates the harmonization of RP syllabus to attain an international recognition. (Author)

The University is located in close proximity to Pickering, Darlington and Bruce Nuclear Power Plants, the fuel manufacturer Cameco, and a number of regional health centres. As such, the initial program focus was to serve the needs of the power utilities and the health sectors. The first programs envisioned and adopted at UOIT were programs in Nuclear Engineering and Radiation Science/Health Physics. These programs are unique in Canada. The four year Bachelor of Science honours degree programs in Radiation Science curriculum includes medical, industrial, agricultural and material science applications, and emphasizes a strong mathematics and science foundation to the discipline. The four year Canadian Engineering Accreditation Board accredited Bachelor of Nuclear Engineering honours program has a strong emphasis on radiation protection, environmental effects of radioactivity, and risk assessment. Both programs have internship options, and both have 'and Management' options, requiring an additional year of study. One key aspect to the pedagogy at UOIT is web-centric learning. Each student is issued a fully equipped internet-ready laptop for use in classes, tutorials and laboratories. The professors endeavor to integrate technology wherever possible to assist the student learning process, for example with on-line testing and course-work submission. Course materials are provided via learning management system software, and instruction is provided for industry standard computational and simulation tools. For courses in radiation protection and environmental effects, there is great emphasis on 'hands on' experience and realistic field exercises. The first graduating class was in spring 2007, and the indication from industry is that the specially trained radiation protection and

    One of the best ways of protection to operators in any radiation practice is to provide him/her with an adequate level of education and training in radiation protection. There are many international references where this fact is pointed out and particularly it is recognized the importance of the introduction of radiation protection courses previously to their work with ionising radiation. The University of Sevilla (Spain) through its Radioisotope Service has been organizing biannually since 1995 Training Courses for Supervisors and Operators of Radioactive Installations for university investigators that use radioactive sources or radiation equipment. The courses are imparted by teachers from the university radioactive installations, hospital physicist specialists from medical physics services and medical doctors from prevention labour health service; all of them are the authors of this communication. The students are postgraduate students or teachers that need operate with ionising radiation in their research laboratories. Up to date, it has been organized 4 courses series with an average of 30 students per course. These courses are homologated by the Nuclear Security Council and let the student obtain the licence for Supervisors or Operators of Radioactive Installations in each of the following applications fields: a) Laboratories with Non-Encapsulated Sources. This application includes research activities in Biology, Chemistry, Physics, Medicine and Pharmacy. b) Radiation Generator Equipment. This last one includes equipment such as X-Rays apparatus for diffraction studies in physics, chemistry and art sciences, or Particle Accelerator for atomic physics research in the National Accelerator Centre. The practical sessions of the courses are imparted in the radioactive installations of the Seville university. In this study it is described the details of the organization of the courses. (Author)

    Radiological protection is in constant motion, raised by new developments and research in the medical and industrial sectors. Radiation protection and safety associated with the application of ionizing radiation depends strongly on the skills and expertise of the professionals. The International Basic Safety Standard places great emphasis on education and training for all persons engaged in activities relevant to the protection and safety. For the professionals involved the most critical aspect it is the radiation protection. NCRRP is an established research center for education and training in radiation protection. Training is conducted by expert trainers with years of experience in the field of radiation protection. NCRRP organized courses and individual training on topics related to radiation protection: enhancing the qualifications of professionals from the medical and non medical fields; specialized training in radiation protection of different groups of professionals working with ionizing radiation sources; postgraduate education in radiation protection education of PhD within existing academic programs and give guidance to Master Students. In parallel the NCRRP aims to play a role in national and international policy through participation in European programs. Such is “CONCERT European Joint Programme for the integration of Radiation Protection Research”. The NCRRP develops, publish and distribute programs, newsletters, manuals and information materials for the benefit of the society. The implementation of a coherent approach to education and training becomes crucial in a world of dynamic markets and increasing workers’ mobility.

    As a governmental Authority the National Board of Nuclear Safety and Radiation Protection of the GDR is responsible for the organization of radiation protection training in the GDR. In compliance with its statute it has to take itself measures for advanced training. The requirements for qualification in radiation protection vary according to the type of work and responsibility, and are laid down in the Radiation Protection Regulations of the GDR. With regard to their tasks and responsibility, persons having knowledge of radiation protection are classified into three major categories: radiation protection specialists (radiation protection officer/responsible medical officer), leading and other staff members. The theoretical and practical advanced training of these groups is different. Up to now over 6,700 leading staff members, 3,700 radiation protection officers, 900 responsible medical officers and 250 radiologists have been trained in more than 400 courses and further short-term training courses. The greatest part of the 'other staff members' of establishment in which work is with ionizing radiation are trained in accordance with internal radiation protection training programmes which are provided and must be approved by the National Board of Nuclear Safety and Radiation Protection. In the GDR there are more than 40,000 occupationally exposed persons. This system of advanced training has proved useful. At present it is being completed by a cycle of short-term courses for advanced training in which all trained persons shall take part in turns of 2 to 5 years depending on their type of work. From 1977, post-graduate studies of nuclear safety and radiation protection terminating with an additional college diploma, will be introduced for senior specialists. At present a new national training centre is being established at the National Board of Nuclear Safety and Radiation Protection of the GDR

    Education and training is a crucial matter in radiation protection and it is considered a regulatory requirement. For this reason, this project work focused on developing an education and training programme for Radiation Protection Officers whose overall function is to oversee radiation protection and safety at the work place. The developed education and training programme has adopted both the class room based and on the job training methods. Additionally, the programme is organized into 6 modules and focuses on fundamentals of radioactivity; biological effects; legislation; principles of radiation protection; assessment and protection against occupational exposure; medical exposure (only applicable to Radiation Protection Officers in the medical sector) and emergency preparedness and response. The purpose of the programme is to provide Radiation Protection Officers with the basic knowledge and skills to function effectively to meet radiation safety and regulatory requirements. (au)

    In the LHC transfer lines, the beam is extremely well controlled and confined. This is managed through a wide variety of superconducting magnets, which focus, defocus and bend the beam. As for the control part, there are numerous monitoring devices co-operating with the SCADA systems, all working for the protection of the instruments and the people. Our work, in particular, falls under the beam transfer lines, TI2 and TI8, between the SPS and the LHC. The protection devices in the transfer lines need to be set up according to the optics of the beam, namely the trajectory inside the beam-pipe. This means that, depending on the trajectory of the beam inside the beam-pipe and the positioning of the protection devices around the beam-pipe, certain adjustments need to be made, so that the beam will not damage or even affect the monitoring devices.

    2009-11-01

    The Radiation and Nuclear Safety Authority (STUK) carried out a survey on the radiation protection training of radiation safety officers (RSO) in Finland in 2008. The aim of the survey was to obtain information on the conformity and uniformity of the training provided in different training organisations. A previous survey concerning radiation protection training was carried out in 2003. That survey determined the training needs of radiation users and radiation safety officers as well the radiation protection training included in vocational training and supplementary training. This report presents the execution and results of the survey in 2008. According to the responses, the total amount of RSO training fulfilled the requirements presented in Guide ST 1.8 in the most fields of competence. The emphasis of the RSO training differed between organisations, even for training in the same field of competence. Certain issues in Guide ST 1.8 were dealt quite superficially or even not at all in some training programmes. In some fields of competence, certain matters were entirely left to individual study. No practical training with radiation equipment or sources was included in the RSO training programme of some organisations. Practical training also varied considerably between organisations, even within the same field of competence. The duties in the use of radiation were often considered as practical training with radiation equipment and sources. Practical training from the point of view of a radiation safety officer was brought up in the responses of only one organisation. The number of questions and criteria for passing RSO exams also varied between organisations. Trainers who provided RSO training for the use of radiation in health care sectors had reached a higher vocational training level and received more supplementary training in radiation protection in the previous 5 years than trainers who provided RSO training for the use of radiation in industry, research, and

    Any action undertaken in technical training must aim at mastering the know-how appropriate to the work to be done. To develop a training program in radiation protection intended for persons who work in radioactive areas it is necessary to analyze the tasks corresponding to the work to be done then to install the means required to implement them. Evaluating the hazards (second stage training) is the sole responsibility of those in charge of work safety assisted where necessary by a specialist on specific hazard (specialized training). But all the staff, knowing the risks involved, must know how to protect themselves (first-stage training). Stage I and 2 trainings are given in site and call for specific teaching methods. It was necessary to create a further training course for them known as stage 3 training to prepare the instructors [fr

  11. Automatic Content Creation for Games to Train Students Distinguishing Similar Chinese Characters

    Science.gov (United States)

    Lai, Kwong-Hung; Leung, Howard; Tang, Jeff K. T.

    In learning Chinese, many students often have the problem of mixing up similar characters. This can cause misunderstanding and miscommunication in daily life. It is thus important for students learning the Chinese language to be able to distinguish similar characters and understand their proper usage. In this paper, we propose a game style framework in which the game content in identifying similar Chinese characters in idioms and words is created automatically. Our prior work on analyzing students’ Chinese handwriting can be applied in the similarity measure of Chinese characters. We extend this work by adding the component of radical extraction to speed up the search process. Experimental results show that the proposed method is more accurate and faster in finding more similar Chinese characters compared with the baseline method without considering the radical information.

    The need for education and training in the various disciplines of radiation protection has long been recognized by the IAEA, the International Labour Organization (ILO), the United Nations Educational, Scientific and Cultural Organization, the World Health Organization and the Pan American Health Organization (PAHO). This need has been partially met through the many training courses undertaken by these organizations, either individually or in collaboration. The IAEA has assisted developing Member States in the training of specialists in radiation protection and safety through its organized educational and specialized training courses, workshops, seminars, fellowships and scientific visits. Training is an important means of promoting safety culture and enhancing the level of competence of personnel involved in radiation protection activities, and has acquired a place in the IAEA's programme accordingly. For example, the IAEA Post-graduate Educational Course in Radiation Protection and the Safe Use of Radiation Sources is regularly offered in countries around the world, and has been provided in Arabic, English, French, Spanish and Russian. The training provided by the IAEA is primarily aimed at regulators, professionals working in radiation protection and those responsible for the development of training programmes in their own countries. The importance of adequate and appropriate training for all those working with ionizing radiation has been highlighted by the results of the IAEA's investigations of radiological accidents. A significant contributory factor in a number of the accidents has been a lack of adequate training, which gave rise to errors with serious consequences. This report provides assistance in organizing training and complying with the requirements on training of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS).

    Education and training are of primary importance for achieving competence in radiation protection. Unfortunately, one records the absence of a national legislation specifying the training of the qualified expert. On the basis of the observation which there exists in the Faculties of Sciences of Morocco the courses in radiation protection within the framework of preparation of the D.E.S.A;/M.A.S.T.E.R., we will propose to create a master in radiation protection within the framework of the reform of the higher education in progress. This reform proposes three levels: licence, Master, Ph.D. According to the B.S.S., any person who is occupationally exposed to ionising radiation or who may be exposed in the course of the work should receive adequate training in radiation protection. The Nuclear Physics Laboratory of Rabat (N.P.L.R.) has participated in the organisation of IAEA postgraduate educational and training courses in radiation protection and the safety of radiation sources since 1998. It is also pioneer in the preparation of the doctorate thesis in radiation protection. The objective of this work is to present the important points of national strategy for building competence in radiation protection and the role of Radiation Protection Group(R.P.D.), created recently at our Physics department, to ensure the organisation of a radiation protection master.

    In the frame of the amendment of the Swiss radiation protection regulations (StSV) the radiation protection education and training system is checked whether there is a need for improvement measures or the regulations have to be revised. Experiences, the comparison with other education and training systems and international developments were compiled and evaluated The responsible expert group with participants from authorities and instructors decided that no fundamental changes are necessary. In the contribution two items are discussed: The mandatory external consulting of licensees by acknowledged radiation protection experts - as required by the EU BSS (basic safety standards) with the definition of a radiation protection expert (RPE) - bears more disadvantages than advantages. On the other hand the improvement potential with respect to clearness and courtesy of requirements for radiation protection education and training in Switzerland were considered in the frame of WU-BSS revision.

    Training active shape models requires collecting manual ground-truth meshes in a large image database. While shape information can be reused across multiple imaging modalities, intensity information needs to be imaging modality and protocol specific. In this context, this study has two main purposes: (1) to test the potential of using intensity models learned from MRI simulated datasets and (2) to test the potential of including a measure of reliability during the matching process to increase robustness. We used a population of 400 virtual subjects (XCAT phantom), and two clinical populations of 40 and 45 subjects. Virtual subjects were used to generate simulated datasets (MRISIM simulator). Intensity models were trained both on simulated and real datasets. The trained models were used to segment the left ventricle (LV) and right ventricle (RV) from real datasets. Segmentations were also obtained with and without reliability information. Performance was evaluated with point-to-surface and volume errors. Simulated intensity models obtained average accuracy comparable to inter-observer variability for LV segmentation. The inclusion of reliability information reduced volume errors in hypertrophic patients (EF errors from 17 ± 57% to 10 ± 18%; LV MASS errors from -27 ± 22 g to -14 ± 25 g), and in heart failure patients (EF errors from -8 ± 42% to -5 ± 14%). The RV model of the simulated images needs further improvement to better resemble image intensities around the myocardial edges. Both for real and simulated models, reliability information increased segmentation robustness without penalizing accuracy.

    Radiation and its various industrial applications have been growing at approximately 10 percent per year for the past decade in Korea. As a result, the importance of the Education and Training (E and T) in radiation protection is of upmost importance. This paper is intended to investigate the present status of the E and T on radiation protection and safety in Korea and to draw up the improvements of the E and T courses required for building the national radiation safety infrastructure. For these purposes, the E and T data from the six major domestic organizations providing radiation protection training courses were investigated and analyzed. Each of the organizations is offering several kinds of E and T courses based on their own specific functions. These organizations have administrative facilities equipped with the latest technology for E and T in radiation protection. The E and T courses mainly cover the training courses for radiation workers, radiological emergency staff, license applicants, license holders, and regulatory staff. In 2010, a total of 58 E and T courses were carried out across six organizations. The conclusions make a number of observations highlighting challenges such as: establishing a formal feedback mechanism, introducing more practical training sessions, developing training courses tailored to the job categories and target audiences, and designing education and training courses in radiation protection that comply with current obligations as well as future requirements.

    The responsibility for providing the necessary assurance that the use of nuclear energy in Canada does not pose undue risk to health, safety, security and the environment is vested with the Atomic Energy Control Board (AECB). This responsibility has led the Operator Certification Division of the AECB to develop methods to obtain assurance that nuclear power plant operations personnel are well trained and adequately competent to perform their duties. The features of the AECB approach to evaluation of training programmes based on a systematic approach to training is described. An overview of the Canadian nuclear power plants' radiation protection qualification levels is given. The developing evaluation process is contributing to the improvement of licensee radiation protection training programmes. This is making possible the transfer of part of the responsibility for licensed personnel radiation protection qualification assessment to the licensees, thus enabling a reduction in the operator certification division formal qualification activities.

    Full Text Available Noise-induced hearing loss (NIHL is a significant clinical, social, and economic issue. The development of novel therapeutic agents to reduce NIHL will potentially benefit multiple very large noise-exposed populations. Oxidative stress has been identified as a significant contributor to noise-induced sensory cell death and NIHL, and several antioxidant strategies have now been suggested for potential translation to human subjects. One such strategy is a combination of beta-carotene, vitamins C and E, and magnesium, which has shown promise for protection against NIHL in rodent models, and is being evaluated in a series of international human clinical trials using temporary (military gunfire, audio player use and permanent (stamping factory, military airbase threshold shift models (NCT00808470. The noise exposures used in the recently completed Swedish military gunfire study described in this report did not, on average, result in measurable changes in auditory function using conventional pure-tone thresholds and distortion product otoacoustic emission (DPOAE amplitudes as metrics. However, analysis of the plasma samples confirmed significant elevations in the bloodstream 2 hours after oral consumption of active clinical supplies, indicating the dose is realistic. The plasma outcomes are encouraging, but clinical acceptance of any novel therapeutic critically depends on demonstration that the agent reduces noise-induced threshold shift in randomized, placebo-controlled, prospective human clinical trials. Although this noise insult did not induce hearing loss, the trial design and study protocol can be applied to other populations exposed to different noise insults.

The plasma outcomes are encouraging, but clinical acceptance of any novel therapeutic critically depends on demonstration that the agent reduces noise-induced threshold shift in randomized, placebo-controlled, prospective human clinical trials. Although this noise insult did not induce hearing loss, the trial design and study protocol can be applied to other populations exposed to different noise insults.

    The establishment of an inter departmental project, financed by the Spanish Ministry of Education, has made possible the development to specific didactic materials on Radiological Protection and Quality Assurance in Medical Radiodiagnostic Practices. These have been published as a manual and practical notebook. This material constitutes the grounding work for the first continuous tele-education training course via Internet that Spanish professionals exposed to ionising radiation are following. Interactive multimedia training and tele-education may become one of the alternatives that allow health science professionals to receive continuous training, provided that adequate content and aims had been established during undergraduate training.

    Some complex data types are capable of modeling data variability and imprecision. These data types are studied in the symbolic data analysis field. One such data type is interval data, which represents ranges of values and is more versatile than classic point data for many domains. This paper proposes a new prototype-based classifier for interval data, trained by a swarm optimization method. Our work has two main contributions: a swarm method which is capable of performing both automatic selection of features and pruning of unused prototypes and a generalized weighted squared Euclidean distance for interval data. By discarding unnecessary features and prototypes, the proposed algorithm deals with typical limitations of prototype-based methods, such as the problem of prototype initialization. The proposed distance is useful for learning classes in interval datasets with different shapes, sizes and structures. When compared to other prototype-based methods, the proposed method achieves lower error rates in both synthetic and real interval datasets. Copyright © 2016 Elsevier Ltd. All rights reserved.

  11. Training in radiological protection - a pool of practical exercises

    Courses in Radiological Protection have been organised at Leeds by the NRPB since its formation, and prior to that by the Leeds Centre of the Radiological Protection Service. From the outset it seemed essential that such courses should contain a practical element, and accordingly a number of exercises were drawn up. Since that time further exercises have been added, often in response to a specific requirement from a customer or group of customers. Most of the exercises have involved the design and construction of 'one-off' items of equipment, a number of which can be considered to represent interesting approaches towards radiological protection teaching. The construction of a 'second generation' of hardware has focused attention on the objectives and design features of the exercises, which in turn has prompted a desire to publish a series of short papers describing the pool of exercises that is currently available for inclusion in the various courses run by the NRPB Centres. The first of these papers puts the series into context and provides a background to the descriptions of specific exercises. (author)

    International Nuclear Information System (INIS)

    2009-01-01

    Education and training are the two basic pillars of any policy regarding safety in the workplace. Practitioners who work with radiation sources will have a wide range of responsibilities and objectives depending on the radiation practice, but all will have a triple common need: a basic education as well as specific training providing the required level of understanding of artificial and natural radiation and its management; standards for the recognition of skills and experience; an opportunity to refresh, update and test acquired knowledge and competence on a regular basis. International meetings, publications and recommendations covering safety culture in the field of radiological protection increasingly stress the need for education and training. In addition, compliance with the requirements of specific European directives and the international basic safety standards is crucial in a world of dynamic markets and increasing workers mobility, and common approaches to training facilitate the understanding of these requirements. The conference intends to address the largest potential audience, covering policy makers, the medical sector, industrial radiographers, NORM experts, the engineering sector, the non-nuclear industry, social sciences researchers, safety experts, radiation protection experts, radiation protection officers, medical physics experts, regulators and authorities. Furthermore, it aims to reinforce the contacts between various organisations, individuals and networks dealing with education and training policies in radiological protection. Special attention will also be paid to attracting and inviting young professionals to ensure knowledge transfer and to help build the future of radiological protection. (authors)

    Since 1978, Sandia National Laboratories has provided training courses in the systematic design of Physical Protection Systems (PPS). One such course, the International Training Course (TC) on the Physical Protection of Nuclear Facilities and Materials, is sponsored by the Department of Energy`s International Safeguards Division , the International Atomic Energy Agency, and the Department of State. Since 1978, twelve 3- and 4-week classes have been conducted by Sandia for these sponsors. One- and two-week adaptations of this course have been developed for other customers, and, since 1994, nine of these abbreviated courses have been presented in the Russian language to participants from the Former Soviet Union (SU). These courses have been performed in support of the Department of Energy`s program on Material Protection, Control and Accounting (MPC&A) for the Russian Federation and the Newly Independent States. MPC&A physical protection training assumes participants have more narrowly defined backgrounds. In using affective approaches, the overall goal of training in the context of the MPC&A Program is to develop modern and effective, indigenous capabilities for physical protection system design and analysis within the SU. This paper contrasts the cognitive and affective approaches to training and indicates why different approaches are required for the ITC and the MPC&A Programs.

    2008-01-01

    Full text: Radiation protection is the science of protecting people and the environment from the harmful effects of ionizing radiation, which includes both particle radiation and high energy electromagnetic radiation. It includes occupational radiation protection, which is the protection of workers; medical radiation protection, which is the protection of patients; and public radiation protection, which is about protection of individual members of the public, and of the population as a whole. ICT has made possible the development of e-learning and several Virtual Learning Environments (VLEs) which can support a wide range of capacity building requirements, ranging from under-graduate and post-graduate programmes, continuing professional development courses, right through to short subject specific and research courses, thereby eliminating the problems of conventional forms of training / learning, some of which are: limited access, cost effectiveness and language / cultural barriers. This paper focuses on the utilization of these ICT-based training / learning for capacity building in radiation protection framework and concludes with suggestions on implementation strategies.

    The International Basic Safety Standards (BSS) for Protection against Ionizing Radiation and for the Safety of Radiation Sources establish the basic requirements for protection against the risks associated with exposure to ionizing radiation and for the safety of radiation sources that may deliver such exposure. One important aspect of the Safety Standard is education and training of all personnel involved in the activities of radiation and radioactive sources. According to the BSS a Radiation Protection Officer is an individual technically competent in radiation protection matters relevant for a given type of practice who is designated by the registrant or licensee to oversee the application of the requirements of the standards. By this assigned role, radiation protection officers for industrial irradiators should be adequately trained since these facilities involve very high dose rates during irradiation, such that a person accidentally exposed can receive a lethal dose within minutes or seconds and fatalities can occur. This training among others things will enable the radiation protection officers to understand practical application of the IAEA Safety Standard to industrial irradiator facilities, understand the requirements for safety assessments and emergency plans, be able to develop a radiation protection programme for irradiators, be familiar with the different types of industrial irradiators and their applications and understand the safety philosophy and design requirements for industrial irradiators.

    The development of the nuclear applications in Cuba has been accompanied by a strong infrastructure of radiological protection, which includes the regulatory system and diverse scientific techniques services needed by the program. It is recognized the fact, that the preparation of the human resources has played an important role in safety levels reached in the practices accomplished. Presently, the processes of selection, training and authorization of the personnel working with ionizing radiations have been regulated. This paper aims at the development of a strategy to create a national system of sustainable education and training in the field of the radiological protection able to accomplish the demands of the regulatory organizations. Present necessities and the perspective of training were analyzed; in addition involved academic and non-academic institutions were identified. The design of the realistic-based national training program is described as well as the responsibility of each of the involved institutions. (author)

    The Directive 97/43 Euratom on medical exposures and the report RP 116 published by the European Commission on Education and Training in radiation protection for medical exposures, established that interventional radiologists should have a more skilled training for handling X-Ray equipment and a better knowledge about the ways of protecting patients and staff against ionising radiation. To analyse the objectives for training in radiation protection recommended in the European Guideline and to show the most important points and modifications for a better practical application of this guide. An inquiry has been performed into the specific objectives recommended by the European Guideline RP 116 about training on Radiation Protection. Twenty interventional radiologists were requested to fill in the test, pointing out the importance of each objective (0-no necessary, 1-medium importance, 2-very important), and they were encouraged to suggest other more interesting for them not included in the European Guideline. The average scores for each of the objectives included in the European Guideline are shown, and an additional relation of suggested topics has been added to the current list. The scoring system show the priority and importance of the objectives that could be taken into account during the next training courses to be held in Spain and it could be used as a base of discussion in some European meeting in order to improve the European Guideline in the future.

    1981-01-01

    In this, the second of a series of papers, an exercise is described in which the objectives are to illustrate some of the problems and underlying principles related to scattered radiation in industrial radiography situations, although the principles involved can be applied to other situations. A model of a radiography room, with a beta emitter as the source of radiation, is used to demonstrate- (i) the scatter of radiation down a maze entrance. (ii) 'airscatter' over the walls of the room. (iii) the effect of beam collimation on dose rates from scattered radiation. (iv) the minimisation of scattered dose rates by judicious direction of the collimated beam. The exercise is strictly qualitative and course participants are positively warned that the results must not be regarded as having any quantitative value. The exercise provokes discussions on a number of topics; typically regarding the economic benefit (in terms of savings in cost of protection) to be derived from being able to limit the size and direction of the useful beam.

    Full text: Purpose: To introduce the radiation protection training program implemented in the radiation oncology department of the Hotel-Dieu de Quebec. This program seeks to provide an adequate training for all the clinic workers and to fulfill Canadian Nuclear Safety Commission's (CNSC) legislations. Materials and Methods: The radiation protection training program implemented is based on the use of five different education modalities: 1) Oral presentations, when the objective of the formation is to inform a large number of persons about general topics; 2) Periodic journals are published bimonthly and distributed to members of the department. They aim to answer frequently asked questions on the radiation safety domain. Each journal contains one main subject which is vulgarized and short notices, these later added to inform the readers about the departmental news and developments in radiation safety; 3) Electronic self-training presentations are divided into several units. Topics, durations, complexity and evaluations are adapted for different worker groups; 4) Posters are strategically displayed in the department in order to be read by all the radiation oncology employees, even those who are not specialized in the radiation protection area; 5) Simulations are organized for specialised workers to practice and to develop their skills in radiation protection situations as emergencies. A registration method was developed to record all training performed by each member of the department. Results: The training program implemented follows the CNSC recommendations. It allows about 150 members of the department to receive proper radiation safety training. The oral presentations allow an interaction between the trainer and the workers. The periodic journals are simple to write while ensuring continuous training. They are also easy to read and to understand. The e-learning units and their associated evaluations can be done at any time and everywhere in the department. The

    Alzheimer's disease (AD) is a leading cause of death and disability among older adults. Modifiable vascular risk factors for AD (VRF) include obesity, hypertension, type 2 diabetes mellitus, sleep apnea, and metabolic syndrome. Here, interactions between cerebrovascular function and development of AD are reviewed, as are interventions to improve cerebral blood flow and reduce VRF. Atherosclerosis and small vessel cerebral disease impair metabolic regulation of cerebral blood flow and, along with microvascular rarefaction and altered trans-capillary exchange, create conditions favoring AD development. Although currently there are no definitive therapies for treatment or prevention of AD, reduction of VRFs lowers the risk for cognitive decline. There is increasing evidence that brief repeated exposures to moderate hypoxia, i.e. intermittent hypoxic training (IHT), improve cerebral vascular function and reduce VRFs including systemic hypertension, cardiac arrhythmias, and mental stress. In experimental AD, IHT nearly prevented endothelial dysfunction of both cerebral and extra-cerebral blood vessels, rarefaction of the brain vascular network, and the loss of neurons in the brain cortex. Associated with these vasoprotective effects, IHT improved memory and lessened AD pathology. IHT increases endothelial production of nitric oxide (NO), thereby increasing regional cerebral blood flow and augmenting the vaso- and neuroprotective effects of endothelial NO. On the other hand, in AD excessive production of NO in microglia, astrocytes, and cortical neurons generates neurotoxic peroxynitrite. IHT enhances storage of excessive NO in the form of S-nitrosothiols and dinitrosyl iron complexes. Oxidative stress plays a pivotal role in the pathogenesis of AD, and IHT reduces oxidative stress in a number of experimental pathologies. Beneficial effects of IHT in experimental neuropathologies other than AD, including dyscirculatory encephalopathy, ischemic stroke injury, audiogenic

    The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document 'Education and

A system of personnel licenses is established considering two levels of required radiation protection training-supervisor and operator according to responsibilities assigned during the operation of the radioactive facilities. This paper present the major advances already done in the educational web site maintained on the CIEMAT server and accessible through the CSN web. The project includes training material for sixteen applied courses and the design of a educational web site to hold pedagogical material for developing distant learning courses. The main objective of this project is to provide training materials for course organisers, trainers and for professional participants and to promote the exchange of expertise between workers involved in all activities using radiation sources. The project also aims to provide necessary mechanism for standardisation of the radiation protection knowledge made available to the exposed workers, including theoretical and practical training. The developed training material included in the project will cover all uses of radioactive sources including medical diagnosis. The web site is being developed of provide educational material on a modular design and in Spanish. The paper presents the initial results of this useful tool for practitioners. Courses are based on core modules with basic and specific modules involving different targets groups, and the contents can be easily adapted for other target groups. For each one of the modules should be included in the web site: objectives, syllabus, lessons and practical sessions, demo and lab exercises, etc. The project includes training tools for sixteen courses based in the standard syllabus content in the Spanish legal framework. In the next future complete materials for trainers will be available to case courses

    An evident purpose of the radiological protection training is to use suitable protective equipment and to behave correctly if unexpected working conditions happen. A major difficulty of this training consist in having the most realistic reading from the monitoring devices for a given exposure situation, but without using real radioactive sources. A new approach is developed at EDF R/D for radiological protection training. This approach combines different technologies, in an environment representative of the workplace but geographically separated from the nuclear power plant: a training area representative of a workplace, a Man Machine Interface used by the trainer to define the source configuration and the training scenario, a geo-localization system, fictive radiation monitoring devices and a particle transport code able to calculate in real time the dose map due to the virtual sources. In a first approach, our real-time particles transport code, called Moderato, used only an attenuation low in straight line. To improve the realism further, we would like to switch a code based on the Monte Carlo transport of particles like Geant 4 or MCNPX instead of Moderato. The aim of our study is the evaluation of the code in our application, in particular, the possibility to keep a real time response of our architecture. (authors)

    The International School for Radiological Protection, a task force within SCK-CEN, co-ordinates and organises training programs on all aspects of radiological protection. IsRP courses are directed as well to the private sector as to the political and academic world and the general public. International meetings, publications and recommendations with regard to safety culture increasingly stress the importance of education and training in the field of radiological protection. In addition, the need to standardise and harmonise the recognition of skills and practices on a national and European level is emerging. In this sense, the objectives of isRP are threefold : (1) to continue the organisation of open courses and training-on-demand of which the programmes are made up according to the background level and training requirements of the participants, and this for the Belgian medical and industrial sector; (2) to come to a closer cooperation with national universities and high schools and relevant international institutions; (3) to contribute to a better harmonisation of training practice and of skills recognition on a national and European level

    The object of this work is to introduce the training program in Radiation Protection implemented in our Hospital, and its evaluation and follow-up. Material AND Methods: The training program in Radiation Protection implanted by the Department of Radiation Protection in the Hospital de la Ribera consists of three types of training modalities: Annual Seminars: applicable to all the exposed workers and divided in a general part and a specific one for each area; Informative lectures: applicable to a specific department, deal with specific issues of interest without predetermined frequency; Individualised training: applicable to pregnant, new workers, job moves and duties change. The follow-up of the program is carried out by mean of inquiries about general and site-specific knowledge on radiation protection. Results The results of the inquiries are analysed and related with the continuous training program. Conclusion: It is remarkable that departments with workers without academic training in radiation protection (Intensive Care Unit, Surgery, Endoscopy,) need a more dedicated training. The results confirm the validity of the three training modalities: The annual seminar provides a continuous training to all exposed workers; the informative lecture is useful to handle immediately issues of current interest in a specific department and the individual training are useful to acquire specific knowledge about radiation risks and radiation protection rules in new working situations.

    Education and training in the radiological protection of patients has to face many challenges. These stem from the interdisciplinary nature of the personnel involved, their varied backgrounds, the difficult to quantify risk and benefit considerations, concern for quality of the end product, changing attitudes as knowledge develops in fast growing areas of technology and the wide complexity of the equipment used. On the one hand there is a need for giving orientation about the medical exigencies and situations in clinical practice to the radiation protection regulators and, on the other, more and more clinicians without any training in radiation protection are getting involved in the use of high levels of radiation through angiographic procedures. It is hence no wonder that the deterministic effects of radiation have been observed in patients undergoing angiographic procedures. A review of the state of the art in education and training and identifying educational challenges is therefore needed. The medical training of physicians and support personnel in the health care use of ionizing or other radiation in patients is particularly challenging for many reasons, most of which are unique to health care. These include those described in the paper. (author)

    Within the European Community and world-wide there is extensive experience in the principles and practice of radiation protection and radioactive waste management. Nuclear skills and capabilities have grown and evolved since the inception of nuclear technology in the 1940s. However, with the current stagnation of the nuclear industry it is increasingly acknowledged that the skills and expertise held by the generation who grew up with nuclear technology are being passed on to new generations of experts. This poses a significant risk to the community who will need to manage nuclear liabilities for long times into the future in order to protect future society from radiological hazards. Notwithstanding that the state of the art in nuclear waste management is undoubtedly high in many organizations, it is very clear that there is continuous need for the provision of education and training in this area. The various training and education programmes throughout Europe are at different stages of development. There is undoubtedly a need for harmonization of the numerous programmes and there would be great benefit to countries at early stages of development due to the learning experiences from the more developed organizations. The objective of CETRAD is to develop proposals for structuring and delivering both education and training in the management of the geological disposal of long-lived radioactive waste and radiation protection across Europe. This proposal is seen as a forerunner of a more comprehensive pan-European Network in this area, which it is planned, will emerge from this work. The project activities will be carried out in two phases. Phase 1 will involve national evaluations of both the needs for education and training and the existing infrastructure and resources in the field of radiation protection and radioactive waste management. Phase 2 will involve development of specific proposals for education and training based on the needs identified in Phase 1. (authors)

    Full Text Available The issues of consumer rights and consumer welfare are increasingly important, especially in the current economic climate in which the ability to make informed choices represents a real advantage in consumers’ daily life. In order to make their purchases with confidence, both in their country and abroad, consumers need easy access to precise information and to professional advice. Taking into account the fact that education and training are a strategic factor for a sustainable development through contribution to human capital development, within the Romania–Bulgaria Cross-Border Cooperation Program 2007–2013, the Academy of Economic Studies in Bucharest, Romania and the D. Tsenov Academy of Economics in Svisthov, Bulgaria decided to collaborate in the field “Cooperation on human resources development – joint development of skills and knowledge”, through the development of cross-border liaisons and exchanges between the two universities. Our objective is to bring up new methods of training in the field of consumer protection in order to train and to supply the labour market with specialized experts in this field in charge with various issues regarding consumers in enterprises, in organizations in charge with elaborating consumer protection policies and in organizations in charge with market supervision and control and also in consumers’ associations. We consider that in this way we meet both consumers’ and employers’ needs because economic agents need professionals in the field as well, in order to advise them in their quest to protect the rights and interests of consumers. Also, Meglena Kuneva, the European Commissioner for Consumer Protection, noted that studies conducted at European level revealed that there is a high level of interest for recruiting qualified experts in the field of consumer protection shown by large companies, national governments, small and medium enterprises and consumers’ associations.

    The European Commission has published and distributed cost free in the main European languages and interactive CD-ROM for Radiation Protection Training in Interventional Radiology (MARTIR project-Radiation Protection Series N. 119-EC 2002). The CD-ROM allows: a) To select different levels of training; b) To follow a training programme as a regular course (step by step) or looking only for the topics of interest; c) To do some auto evaluation multiple choice questions at the end of the different sections or topics; d) To perform a final examination at the end of the course and to have a certification with the total time dedicated to the training programme and the obtained score in final examination. During 2001 and 2002 the MARTIR material has been distributed for evaluation purpose to different experts and it has been used in different pilot courses. In this paper the experience of using this interactive CD-ROM is discussed. The University Complutense of Madrid offers an optional specific training on Radiation Protection for the students of Medicine during their clinical period (4th to 6th year). About 100 hundred students are enrolled per year, 10% of these students follow the MARTIR CD at home as a pilot course. All of them used the CD at Least during 40 hours, completed the low level step-by-step course and pass the exam (score over 75% for 60 multiple choice questions. 87% of the students after finishing the course stated that this education methodology was very suitable for them.

    The companies that are working in decontamination, dismantling and assessment in nuclear power plants, usually have their employees in different facilities far from its central offices. When there is a training in radiological protection applied to the nuclear field, it is difficult for these people the attendance to the course because of different reasons as the location of the formation centres which sometimes are not near from the nuclear facilities, so they usually cannot attend their daily work with the same effectiveness. In this work we present a postgraduate training in radiological protection supervised by Polytechnical University of Valencia (Spain) applied to nuclear and radioactive facilities by a technological platform developed in collaboration with the university. This platform is adapted and designed to different high level contents and applications in different areas and sections, related to a general part, radioactive facilities, nuclear facilities and advanced concepts. When the student finishes an area, an evaluation has to be done to prove the understanding of the lessons. We have included films of different activities as decontamination devices, radiation detectors..etc with the contents to make the explanations more understandable to the student. The course is complemented with a final review and exam that are not online to guarantee that the training is well finished. In addition the student has some practice related with different items explained during the training as the use of equipment in radiological protection tasks. This type of training is more flexitime and can be adapted to the necessities of each user, avoiding high costs and unnecessary displacements. (author)

    The earliest courses in 'Radiation Protection (RP) Education and Training in the Netherlands' date back to the late fifties, a time which saw major developments especially in both nuclear medicine and nuclear power. The Dutch Society for Radiation Protection (NVS - Nederlandse Vereinigung voor Strahlingshygiene), established in 1960, is in fact the result of one of the first RP courses for medical doctors. The current system of recognition of RP courses was implemented in 1984 in Dutch legislation, based on an advice of the Dutch Health Council from 1972 (.). The recognition system has fundamentally remained unchanged since then. Radiation protection courses in the Netherlands based on this system already started in the seventies. After many discussions in the past decade the system will change in the next years in close relation to the start of a system of registration of RPes. In this paper I will start with a short introduction of the Dutch system of RP education and training. I will consecutively describe the background of the future changes in our system. Finally the major changes will be given. In the end I hope to have convinced you of the fact that although we face some major changes in the near future, the basis of the current system of education and training in RP will remain. (orig.)

    Recent studies have shown that there is a wide variety of approaches to education and training of the Qualified Expert across the European Union. National education and training programmes show often large differences in content, duration, level, the introduction of practical work, etc. As they stand, such differences are a barrier to the mutual recognition of the Qualified Expert status and, in part, are contributing to a perceived shortage in expertise in radiation protection and safety. The overall aim of ENETRAP is to determine mechanisms that in the longer term will facilitate better integration of education and training activities (with a view to mutual recognition across the European Union) and to ensure the ongoing provision of the necessary competence and expertise at the level of the Qualified Expert. The ENETRAP project is a 6FP coordination action. It started in April 2005 and runs over a period of 24 months. (authors)

    Hospitals distant from the immediate site of an incident involving a hazardous materials (HAZMATs) release which could include chemical warfare agents, must develop emergency response plans (ERPs) to protect healthcare professionals if they receive potentially contaminated victims. The ERP must address OSHA, EPA, and JCAHO requirements. The VHA convened groups to develop a hazard and exposure assessment, identify actions for compliance with existing regulatory standards, and review site and operational planning issues. Exposure modeling results were used to derive relationships between operational parameters (time and distance from sites/sources) and potential exposure for healthcare workers. According to exposure modeling, level C personal protective equipment is adequate to protect hospital staff distant from the chemical release site. Decontamination runoff and contaminated clothing should also be controlled to limit exposure. Development and coordination of ERPs must include the local emergency planning committee, with clear assignment of tasks, locations, and training in order to prevent exposures to healthcare workers.

    Acute myocardial infarction (AMI) represents a major cause of morbidity and mortality worldwide. Exercise has been proved to reduce myocardial ischemia-reperfusion (I/R) injury However it remains unclear whether, and (if so) how, exercise could protect against AMI. Mice were trained using a 3-week swimming protocol, and then subjected to left coronary artery (LCA) ligation, and finally sacrificed 24 h after AMI. Myocardial infarct size was examined with triphenyltetrazolium chloride staining. Cardiac apoptosis was determined by TUNEL staining. Mitochondria density was checked by Mito-Tracker immunofluorescent staining. Quantitative reverse transcription polymerase chain reactions and Western blotting were used to determine genes related to apoptosis, autophagy and myocardial energy metabolism. Exercise training reduces myocardial infarct size and abolishes AMI-induced autophagy and apoptosis. AMI leads to a shift from fatty acid to glucose metabolism in the myocardium with a downregulation of PPAR-α and PPAR-γ. Also, AMI induces an adaptive increase of mitochondrial DNA replication and transcription in the acute phase of MI, accompanied by an activation of PGC-1α signaling. Exercise abolishes the derangement of myocardial glucose and lipid metabolism and further enhances the adaptive increase of mitochondrial biogenesis. Exercise training protects against AMI-induced acute cardiac injury through improving myocardial energy metabolism and enhancing the early adaptive change of mitochondrial biogenesis. © 2015 S.

    This work aims to verify the actual conditions for the training of technicians in Radiology, in relation to the knowledge of radiation protection in the field of Medical Diagnostic Radiology. To evaluate the knowledge of professionals was prepared a questionnaire on the topic, having been answered by workers with varied experience. The questionnaire was divided into three parts, being the initial self-evaluation, followed by closed and open issues, all specific knowledge. With a total of 55 questionnaires answered, it was found that 85% of respondents consider themselves able to work in the area performing the function, but when questioned about the technical details regarding the exposure to ionizing radiation, it was found that only 15% of respondents had some knowledge about the subject. In relation to Radiological Protection, was found that little more than 10% of the respondents know about the subject. The results found in this survey outlined the creation of a technical specialization course in radiation protection, which is part of the permanent staff of course of the Polytechnical School of Health of FIOCRUZ, solving, partially, one of the problems pointed out today by health bodies, that is the lack of trained personnel

    The oil and gas industry makes extensive use of radioactive sources potentially dangerous to human health and to the environment if not properly controlled, including: industrial radiography, radioactive gauges, well logging activities, use of radiotracers. In addition, the accumulation of natural radionuclides (T.E.N.O.R.M.) may occur in the Oil and Gas extraction and treatment plants. Eni S.p.A. operates in more than 70 countries, with a staff of 79000 employees, in all climates and environments, including the most arduous conditions, and is continuously challenged to achieve high efficiency of operation while maintaining a high standard of safety, including the radiation protection aspects. Thus, in order to maintain the control over occupational exposures to radiation, to protect the public and the environment, and in order to deal with local rules and authorities, it has been developed a Radiation Protection Professional Model including three different roles (Radiation Protection Management, Radiation Protection Coordination and Operational Radiation Protection) that could be associated with the corresponding functions: Radiation Protection Expert, Radiation Protection Advisor, Radiation Protection Specialist. The Professional Model is a global Eni tool devoted to the know-how and the development of the human resources, including health, safety and environmental aspects, through the identification of detailed skills and knowledge. In order to provide the required knowledge to Eni workers all over the world, it has been developed a programme for education and training in radiation safety in collaboration with Eni Corporate University, the Eni company that manages orientation, recruitment, selection, training and Knowledge Management. Different training courses are organized to provide the training both for the Radiation Protection Coordination role (Radiation Protection Advisor course) and for the Operational Radiation Protection role (Radiation Protection

    In the frame of the amendment of the Swiss radiation protection regulations (StSV) the radiation protection education and training system is checked whether there is a need for improvement measures or the regulations have to be revised. Experiences, the comparison with other education and training systems and international developments were compiled and evaluated The responsible expert group with participants from authorities and instructors decided that no fundamental changes are necessary. In the contribution two items are discussed: The mandatory external consulting of licensees by acknowledged radiation protection experts - as required by the EU BSS (basic safety standards) with the definition of a radiation protection expert (RPE) - bears more disadvantages than advantages. On the other hand the improvement potential with respect to clearness and courtesy of requirements for radiation protection education and training in Switzerland were considered in the frame of WU-BSS revision.

    This document deals with the policies and practices of the Environmental and Occupational Safety Division (EOSD) at the Oak Ridge National Laboratory (ORNL) in regard to the selection, training, qualification, and requalification of radiation protection staff assigned to reactor and nonreactor nuclear facilities. Included are personnel at facilities that: (1) operate reactors or particle accelerators; (2) produce, process, or store radioactive liquid or solid waste; (3) conduct separations operations; (4) engage in research with radioactive materials and radiation sources; and (5) conduct irradiated materials inspection, fuel fabrication, deconamination, or recovery operations. The EOSD personnel also have environmental surveillance and operational and industrial safety responsibilities related to the total Laboratory

    The current regulation, established by NOM-229-SSA1-2002 standard, T echnical requirements for facilities, health responsibilities, technical specifications for equipment and facilities for radiation protection in medical diagnosis with X-rays, t hat should be credited refresher courses, and training in radiation safety in accordance with current regulations, however, has been observed that the assistance and accreditation of courses is basically to cover administrative and regulatory requirements and therefore does not necessarily cover needs of the patient to radiation protection in the use of old and new technologies. David Brenner and Eric Hall claim that between 1.5 and 2% of all cancers in the USA may be attributable to exposure to X-ray computerized tomography techniques, given the intensive use of these techniques and the patient dose ranges in which incurred. While this is not debatable, if it is, the alternative does not seem to be abandoning the use of computerized tomography, because it gives them undoubted benefits with respect to invasive procedures. Deserves mention concerns the use of computerized tomography in children using scanning protocols designed for adults, in which case it incurs in 5 times higher dose. An additional warning about unwarranted use of computerized tomography is a procedure of this technique in abdomen resulting in an equivalent dose to 298 times that of a mammogram. Additional aspects such as biological effects (including deterministic) of both medical staff and patients of interventional procedures further reinforces the idea that there are education programs in radiation protection. Attention must put in the new generations, including in the curricula of medical residencies in radiology, endoscopy, cardiology and orthopedic, the education (no emerging courses) in radiation protection, radiobiology, radiology physics, and other topics, but previously must have medical physicists in radiology available to train new

    Current radiation protection is a very sophisticated and elaborate domain where, once the information about the exposure of persons is known in terms of the quantity of the effective dose, we can predict resulting radiological consequences related to the stochastic risk to the health of the exposed persons without a need for other details. In fact, the effective dose contains all pertinent information including the average organ dose distribution and relevant radiation and tissue weighting factors which take into account the specific effects of different types of radiation and selected tissue radiosensitivity. Since the effective dose cannot be measured directly, one has to rely on the monitoring of other appropriate measurable quantities and then do some conversions. The current structure of radiation protection quantities includes too many quantities, the definitions of some of which are not easy to understand and interpret. Moreover, there are numerous quantities based on the dose equivalent, such as the equivalent dose, effective dose, committed equivalent dose, committed effective dose, collective equivalent dose, collective effective dose, personal dose equivalent, ambient dose equivalent and directional dose equivalent, where the only unit of Sv is used.. There are a number of cases in open literature reflecting the difficulties and mistakes in the use of radiation protection quantities. Even more complicated situations are encountered in the field, where the staff responsible for personal and workplace monitoring is confused because of so many different quantities and where the staff may not be qualified and experienced enough to be able to make the relevant conversions and interpretations. The paper summarizes our experience in teaching students and lecturing in various training courses addressing radiation protection where the primary task was to ensure that all radiation protection personnel understood the quantities and units used in radiation

    Automatic sequences are sequences which are produced by a finite automaton. Although they are not random they may look as being random. They are complicated, in the sense of not being not ultimately periodic, they may look rather complicated, in the sense that it may not be easy to name the rule by which the sequence is generated, however there exists a rule which generates the sequence. The concept automatic sequences has special applications in algebra, number theory, finite automata and formal languages, combinatorics on words. The text deals with different aspects of automatic sequences, in particular:· a general introduction to automatic sequences· the basic (combinatorial) properties of automatic sequences· the algebraic approach to automatic sequences· geometric objects related to automatic sequences.

    Safety in the use of ionising radiation and protection against potential risks due to exposure to radiation sources are not static concepts, rather their evolution runs parallel with an increased knowledge of the technologies and basic concepts employed. Education and training, which are inherently tied to with research, are the means to disseminate the advances made to the scientists and professionals working with ionising radiation. At present, Radiation Protection (RP) training is considered to be the best means to promote a safety culture and to improve the competence of exposed workers. Indeed, progress in both RP teaching and training, which form part of this transfer of technology and specialized knowledge, are fields that are in continuous motion. The first conference on Radiation Protection training was celebrated in Saclay (France) under the slogan Radiation Protection: What are the Future Training needs?. It can be considered as the first such meeting dedicated to the community of professionals, from a wide range of scientific and technological backgrounds, related in some way to Radiation Protection training.

    Non-academic members of research teams, such as community members, can perceive traditional human subjects protection training as lacking in cultural relevance. We present a case exemplar of the development of a human subjects protection training for research staff with limited English proficiency and/or no or limited research experience. Seven modules were adapted for language, cultural examples, etc., from the standard Collaborative Institutional Training Initiative (CITI) human subjects protection training. Non-academic research staff completed a day-long training in human subjects protection (six modules) and our research protocol (one module). We assessed comprehension of content with PowerPoint slides and module quizzes. All participants successfully passed each module quiz with ≥ 80% correct. Questions answered incorrectly were discussed before proceeding to the next module. To meet the increasing demand for collaborative community-engaged research with underserved minority populations, human subjects protection training protocols can be adapted successfully to reflect real-world situations and provide culturally relevant materials to help non-academic research staff better understand the importance and necessity of research ethics.

    According to the rules of safety at the working places in Israel, all radiation employees in Israel should receive once a year a refreshing course in several areas of safety. At the NRC-Negev there are two kinds of radiation employees: the ''hot area'' employees, who work in an environment of radioactive materials or radiation machines and the ''old area'' employees (all the other employees in the NRC-Negev). One of the main goals of the Department of Human Resources Development and Training at the NRC-Negev was to organize safety refresher courses. All ''hot area'' employees received a training program of two days in safety subjects, each year. The ''cold area'' employees received the same course, each second year. The former training program included several lectures in radiation protection, health physics, biological effects of ionizing radiation, etc., as well as same lectures in industrial safety, fast aid, fee fighting, emergency procedures, etc. The safety refresher courses were given by Rental lectures. There were a lot of disadvantages in these frontal lectures: The lecturers are employees of the NRCN who had to stop their routine work in order to lecture; the lecturers had to carry out identical training for each course for a large group of workers; there was a lack of testing methods or any other certification for the employees. Recently, seven safety courseware were developed by the NRC-Negev and the CET (Centre for Educational Technology), in order to perform these safety refresher courses. The courseware are based on an interactive computerized training including tutorials and quiz. The tutorial is an interactive course in each subject. The employee gets a simple and clear explanation (including pictures). After each Morial there is a quiz which includes 7 American style questions. The first two courseware are for all the employees, the next 4 courseware for the ''hot area'' employees, and the seventh for the ''cold area'' employees (the seventh is a

    The General Regulation of Radiological Security establishes in its article 159 that the occupationally exposed professionals will have to count on the authorization of the National Commission of Nuclear Security and Safety (CNSNS) with respect to their training. The Mexican official norm NOM-157-SSA1-1996: Protection and radiological safety in the medical diagnosis with X-rays, indicates that the personnel must receive and accept the information, instructions and training related to the protection and radiological safety, in order to accomplish their work according to the requirements and obligations established in the outstanding procedures. Therefore it was designed an initial training course of instructors in the field of the radiological protection to train occupationally exposed professionals who work in the medical diagnosis establishments with X-rays. The didactic material was elaborated considering a period of training of 10 working days, 8.0 daily hours considering theoretical topics, as well as 11 practical. It is used a conventional radiology equipment, a ionization chamber of brand INOVISIOB model 451 P-DE-SI for increasing the radiation levels, and equipment Radical model 9015 with two ionization chambers of 150 cc and 150 cc respectively, as well as a calibrated plates game of aluminium type 110 and a phantom of acrylic as disperser. To date 73 persons have been trained, from which only 37% approved the initial training course. It has been seen that it is necessary to count on a previous training in the filed of the radiological protection to better profit from this training, since if students do not have good bases it is not possible for them to learn all the content in only 80 hours. To date it has been trained to 73 persons, of alone those which 37.0% approved the initial. (Author)

    The contribution describes the new VR-1 training reactor control and power protection system at the Czech Technical University in Prague. The control system provides safety and control functions, calculates average values of the important variables and sends data and system status to the human-machine interface. The upgraded control system is based on a high quality industrial PC. The operating system of the PC is the Microsoft Windows XP with the real time support RTX of the VentureCom Company. The software was developed according to requirements in MS Visual C. The independent power protection system is a component of the reactor safety (protection) system with high quality and reliability requirements. The digital system is redundant; each channel evaluates the reactor power and the velocity of power changes and provides safety functions. The digital part of the channel is multiprocessor-based. The software was developed with respect to nuclear standards. The software design was coded in the C language regarding the NRC restrictions. Configuration management, verification and validation accompanied the software development. Both systems were thoroughly tested. Firstly, the non active tests were carried out. During these tests, the active core of the reactor was subcritical; the input signals were generated from HPIB and VXI controlled instruments to simulate different operational and safety events. The software for instruments control and tests evaluation utilized Agilent VEE development system. After the successful non active checking, the active tests followed. (author)

    IAEA 's education and training activities in radiation, transport and waste safety follow the IAEA vision, strategy and resolutions of its annual General Conferences and reflect the latest IAEA standards and guidance. IAEA prepared a Strategic Approach to Education and Training in Radiation and Waste Safety (Strategy on Education and Training) aiming at establishing, by 2010, sustainable education and training programmes in Member States, which was endorsed by the GC(45)/RES/10C in 2001. In implementing the strategy, IAEA is organising training events at the regional level and assisting the Member States at the national level by providing them the exemplary quality of training material developed at the IAEA. This work will continue ensuring its completeness in all areas of radiation safety. An Inter Centre Network between the Agency and regional, collaborating national training centres is established to facilitate information exchange, improve communication and dissemination of training material. There is a challenge to enhance the technical capability of the Member States to reach sustainability. This is intended through organising number of Train the Trainers events to develop a pool of qualified trainers. The new developments include establishing E-learning, developing a syllabus for training of Radiation Protection Officers and training materials, information materials for radiation workers. These are aimed at assisting Member States attain self sustainability. (author)

    The level of knowledge provided by the Tbilisi State Medical University (TSMU) standard curriculum modules in 'Medical physics' and 'Radiation risk estimates' was assessed as was the learning outcome of modern standards elective course in 'Radiation protection'. Two groups of medical students were examined: Group 1: 5 y students, participants in elective course 'Radiobiology and radiogenic health risk' and Group 2: 1-2 y students, participants in winter and summer schools. Students were tested before and after training courses with the same tests questionnaire. The results of the tests showed the necessity for improvement of the educational curriculum. The changes needed are the inclusion of a basic radiobiological course in the curricula of the faculty of medicine and expansion of the medical physics course through a more detailed presentation of medical imaging methods.

    Full text: As in other countries, life expectancy is increasing in Brazil, and the number of radiological examinations tends to increase. Old equipment and high technology ones cohabit, radiology technicians are not well prepared to conduct practices, images and doses to patients are not optimized. Digital techniques that began to be introduced in the last years are also an important issue, because, as it is possible to modify the image digitally, there is less concern about the choice of equipment parameters that produce the best-image/lowest-dose compromise. Pediatric radiology, CT and fluoroscopy require attention too, as they are of dosimetric interest or because the patient ages imply higher risks or because the techniques deliver higher doses than the conventional ones. In our opinion, the most important role that we can play is educating and forming people to work in this area: training programs and refreshing courses are a way of facing the problem. This way, we are organizing, in a technical cooperation with IAEA, two training courses in quality assurance and radiation protection in radiology, one designed to physicists (60 h), and the radiological technicians (40 h). An important cooperation with a paediatric and a general hospital made it possible to offer courses with 50% practical lessons, performed both in the University and in hospital equipment. Both courses cover a basic Radiation Physics program, radiation protection, image formation and quality control in conventional and digital equipment, and patient dosimetry. Equipment donated by IAEA facilitate the practical QA and dosimetry lessons. The rationale of our project is making it sustainable through the formation of physicists that will go on in the education process of technicians in technical schools. We present the results of the first two courses (physicists and technicians), considering the selection process, the development of the activities, and the assessment both of the students enrolled

    This paper presents an overview of the different agents that are involved in training on Radiation Protection in Spain. The main circumstances which can introduce new challenges in radiation protection practices are reviewed, namely the planned modifications in the regulation framework, the mobility of European workers, the consequences of deregulation of the electric system, the moratorium of the Spanish nuclear programme and the changes in Spanish studies resulting from implementation of the European Higher Education Area. In relation to the contributions that university groups can develop in this field, the author makes some suggestions according to his own experience in the Technical University of Catalonia. It is emphasized that this contribution must be characterized by its quality, credibility and independence. It should include activities such as development of R and D studies, the implementation of accredited laboratories, organization of post-graduate courses, preparation of teaching materials and technical publications, and collaboration with public institutions, scientific and professional societies and other organizations. Finally, the other new activity that is stressed is related to the efforts required to improve information and communication to the stake holders and a growing social interest. (Author)

    2013-04-01

    A training programme for staff of irradiation facilities especially radiation safety officers at industrial irradiation facilities has been developed. The programme focused on technical and administrative basis for ensuring radiation safety at the practices. It consists of thirteen modules ranging from fundamentals of radiation, biological effects of ionizing radiation as well as the technical and administrative issues pertinent to radiation safety of the sources. The overall objective of this programme was to build competence in the area of radiation protection and raise the confidence level of staff of industrial irradiation facilities. The modules are structured in a manner that attempts to give a good understanding to participants on safety features of irradiators and use of radiation monitoring equipment. Each module has specific objectives and expected outcome and the course content is also stated under each module. The duration of the whole programme is sixteen weeks and the participants are expected to have some working knowledge in radiation protection and safe use of radiation sources. (au)

    This document aims to trace the evolution of the CEC radiation protection programme over its 30 years of existence. During this time, research carried out in the framework of the Community programme has made major contributions to the scientific understanding of the action of ionizing radiation and the protection of man and his environment. This information was crucial for developing better radiation protection management for existing and new technologies and for providing the scientific basis for the regulatory activities of the Commission. One important feature of the programme was the success of bringing together scientists from different Member States to cooperate in the various fields of radiation protection and to integrate different areas of radiation protection research into a coherent approach. The structures thus developed within the programme have enabled research in radiation protection to be conducted in a cost-effective manner on behalf of the Member States. This document aims also to give a synopsis of the most important results of the 1985-89 radiation protection programme. This period was characterized by two challenges, the integration of two Member States into Community research and the impact of the Chernobyl accident. The programme has, in spite of reduced funding, continued to provide a high degree of expertise for the Community in the context of the needs in radiation protection. This has been explicity acknowledged in the evaluation of the 1980-89 programmes carried out by an independent panel

  20. Research on transdisciplinary aspects of education and training in radiological protection

    Due to the typical characteristics of ionising radiation, the radiological risk is a very specific one. Risk governance has to take into account as well scientific uncertainties related to biological effects, the distribution of benefits and burdens as well as different perceptions on the risk and on the usefulness of the specific applications of ionising radiation as such. It is not always easy for theorists and practitioners with a certain responsibility to grasp al the facets and nuances of this risk and of the social dynamics in face of it. As well the nuclear worker, the medical doctor as the policy maker or any other person working within an application field of ionising radiation could face situations requiring action where, apparently, the available factual knowledge does not lead unambiguously to a way forward that is 'justified enough' in relation to the potential risk. And if the solution would be justified for him/her, it could be that others involved have different opinions. Having this in mind, it is clear that education and training in RP - seen as a continuous learning process - should elaborate on as well the socio-technical complexity of 'risk assessment' as on the conditions and methodologies to 'find a way out'. This research aims at developing an argumentation for an approach to education and training in radiological protection (RP) and ALARA practice that is broader than the 'classical' acquiring of factual knowledge related to physics and regulation. As for most other areas where applications of a technology are connected to a certain risk, the complexity of applications of radioactivity and nuclear technology has generally technical as well as social dimensions

    As part of its training and information programme on radiation protection, the Directorate-General for Employment and Social Affairs (Health and Safety Directorate) organized for the third and fourth time (in October 1977 and 1978) seminars on radiation protection on behalf of trade union representatives from the nine Member States; the seminars served in particular as a forum for the exchange of ideas and experiences. The present volume reproduces the papers read on those occasions, covering the following topics: the independence of radiaton protection units; training and information in radiation protection; analysis of the main innovations in radiological protection concepts emerging from ICRP Publication No 26; the protection of occasionally exposed workers; the work of the United Nations Scientific Committee on the Effects of Atomic Radiation; the concept of optimization; future developments in dosimetry. Although the publication is destined mainly for the participants in the two meetings, the information it contains may also be of use to anyone interested in the problems of radiation protection and the spreading of knowledge in this field

    Military activities in hot environments pose 2 competing demands: the requirement to perform realistic training to develop operational capability with the necessity to protect armed forces personnel against heat-related illness. To ascertain whether work duration limits for protection against heat-related illness restrict military activities, this study examined the heat strain and risks of heat-related illness when conducting a military activity above the prescribed work duration limits. Thirty-seven soldiers conducted a march (10 km; ∼5.5 km h -1 ) carrying 41.8 ± 3.6 kg of equipment in 23.1 ± 1.8°C wet-bulb globe temperature. Body core temperature was recorded throughout and upon completion, or withdrawal, participants rated their severity of heat-related symptoms. Twenty-three soldiers completed the march in 107 ± 6.4 min (Completers); 9 were symptomatic for heat exhaustion, withdrawing after 71.6 ± 10.1 min (Symptomatic); and five were removed for body core temperature above 39.0°C (Hyperthermic) after 58.4 ± 4.5 min. Body core temperature was significantly higher in the Hyperthermic (39.03 ± 0.26°C), than Symptomatic (38.34 ± 0.44°C; P = 0.007 ) and Completers (37.94 ± 0.37°C; Pmilitary force. The dissociation between heat-related symptoms and body core temperature elevation suggests that the physiological mechanisms underpinning exhaustion during exertional heat stress should be re-examined to determine the most appropriate physiological criteria for prescribing work duration limits.

    We investigated the impact of mindfulness training (MT) on working memory capacity (WMC) and affective experience. WMC is used in managing cognitive demands and regulating emotions. Yet, persistent and intensive demands, such as those experienced during high-stress intervals, may deplete WMC and lead to cognitive failures and emotional disturbances. We hypothesized that MT may mitigate these deleterious effects by bolstering WMC. We recruited 2 military cohorts during the high-stress predeployment interval and provided MT to 1 (MT, n = 31) but not the other group (military control group, MC, n = 17). The MT group attended an 8-week MT course and logged the amount of out-of-class time spent practicing formal MT exercises. The operation span task was used to index WMC at 2 testing sessions before and after the MT course. Although WMC remained stable over time in civilians (n = 12), it degraded in the MC group. In the MT group, WMC decreased over time in those with low MT practice time, but increased in those with high practice time. Higher MT practice time also corresponded to lower levels of negative affect and higher levels of positive affect (indexed by the Positive and Negative Affect Schedule). The relationship between practice time and negative, but not positive, affect was mediated by WMC, indicating that MT-related improvements in WMC may support some but not all of MT's salutary effects. Nonetheless, these findings suggest that sufficient MT practice may protect against functional impairments associated with high-stress contexts.

    A virtual campus, which web address is http://campus virtual.cv.uma.es/, has been created at the University of Malaga. This web site is based on the Moodle Platformer. It consists on a software system designed to help the teacher to create online teaching easily. The main aim of this work is to evaluate the acceptance of this tool by the students, and to compare its utilization with the grades obtained in the Final Exam of June by these students. The whole entrances in the site of the 145 participating students registered trough the course are 7671, which supposes an average of nearly 53 entrances per year per student. The 11.04% of the students have never entered in this site. The students who have obtained the best grades are the ones who have used more this teaching tool. These tools based on new technologies will be a very important support for radiological protection training, which is recommended by International Organizations (EC Report R116 and IAEA Action Plan 2002-2006).

    The beginning of the Vandellos 1 NPP decommissioning set the starting point of an ambitious communication programme addressed to the different kinds of stake holders which composed the social environment of the site. The National Radioactive Wastes company (ENRESA), as the project performed and the legal responsible for the site, designed a communication plan with a clear formative drive and aimed at total transparency in a event which had not taken place before in Spain. All aspects of Safety became strategic values for the project and, therefore, for its communication activities. This was especially the case with regards to public information and Radiological Protection (RP) training. The seminars for the media, the presentations for the interested organizations and environmental collectives and the informative meetings with the political authorities were accompanied by a discourse and several formative initiatives addressed to the general public, and especially to student visitors. those activities have been developing alongside the decommissioning process, from the organization of visits which made possible an in situ view of the RP procedures to the current offer of a specific RP workshop.

    2004-01-01

    In autumn 2003 the Austrian standard OENORM S 5207 with the title R adiation protection training of intervention persons in the case of radiological emergency situations w ill be published. The standard is directed to persons who have to invent in case of a radiological emergency, security forces and as well training centres. The standard has to fulfil three objectives: 1. Regulation of the minimum requirements for the radiation protection training and education of intervention persons. 2. Harmonization of the radiation protection and training of different security forces, for instance Austrian army, Red Cross Austria, Fire Department, Police Department. 3. Mutual recognition of parts of the education between the different security forces. To fulfil these aims the standard is structured in different education modules. If , for instance, a person attended a special training module at the Austrian military, this part of the education is also valid for a career at the Fire Department. Further the modular structure of the education gives the possibility for persons of a special security force to attend one or more modules at another security force. This will lead to an improved cooperation between the different security forces in case of a radiological emergency situation. The education is structured in four levels. The topics of the standard are: 1. Requirements for training centres 2. Guidelines for the examinations of the candidates 3. Topics and goals of the basic education 4. Topics and goals of the advanced education level one 5. Topics and goals of the advanced education level two 6. Topics and examples of specialised education 7. Obligatory further education once every year. (Author)

    The International Training Course on Physical Protection of Nuclear Facilities and Materials was intended for representatives from the developing countries who are responsible for preparing regulations and designing and assessing physical protection systems. The first part of the course consists of lectures on the objectives, organizational characteristics, and licensing and regulations requirements of a state system of physical protection. Since the participants may have little experience in nuclear energy, background information is provided on the topics of nuclear materials, radiation hazards, reactor systems, and reactor operations. Transportation of nuclear materials is addressed and emphasis is placed on regulations. Included in these discussions are presentations by guest speakers from countries outside the United States of America who present their countries' threat to nuclear facilities. Effectiveness evaluation methodology is introduced to the participants by means of instructions which teach them how to use logic trees and the EASI (Estimate of Adversary Sequence Interruption) program. The following elements of a physical protection system are discussed: barriers, protective force, intrusion detection systems, communications, and entry-control systems. Total systems concepts of physical protection system design are emphasized throughout the course. Costs, manpower/technology trade-offs, and other practical considerations are discussed. Approximately one-third of the course is devoted to practical exercises during which the attendees participatein problem solving. A hypothetical nuclear facility is introduced, and the attendees participate in the conceptual design of a physical protection system for the facility.

    Sleep loss is a risk factor for cardiovascular events mediated through endothelial dysfunction. To determine if 7weeks of exercise training can limit cardiovascular dysfunction induced by total sleep deprivation (TSD) in healthy young men. 16 subjects were examined during 40-h TSD, both before and after 7weeks of interval exercise training. Vasodilatation induced by ACh, insulin and heat (42°C) and pulse wave velocity (PWV), blood pressure and heart rate (HR) were assessed before TSD (controlday), during TSD, and after one night of sleep recovery. Biomarkers of endothelial activation, inflammation, and hormones were measured from morning blood samples. Before training, ACh-, insulin- and heat-induced vasodilatations were significantly decreased during TSD and recovery as compared with the control day, with no difference after training. Training prevented the decrease of ACh-induced vasodilation related to TSD after sleep recovery, as well as the PWV increase after TSD. A global lowering effect of training was found on HR values during TSD, but not on blood pressure. Training induces the decrease of TNF-α concentration after TSD and prevents the increase of MCP-1 after sleep recovery. Before training, IL-6 concentrations increased. Cortisol and testosterone decreased after TSD as compared with the control day, while insulin and E-selectin increased after sleep recovery. No effect of TSD or training was found on CRP and sICAM-1. In healthy young men, a moderate to high-intensity interval training is effective at improving aerobic fitness and limiting vascular dysfunction induced by TSD, possibly through pro-inflammatory cytokine responses.(ClinicalTrial:NCT02820649).

    One of the main goals of the Department of Human Resources Development is to give employees fundamental knowledge, refreshing know-how and increasing safety awareness. In this regard safety deals with risks in operating nuclear facilities, including radiation, industrial risks and fire. Israeli Work Supervision (informing and training employees, 1992) (1) and work safety regulations (industrial safety and health for ionization radiation employees) state the need for training by the employer at least once a year. The employer also must take means to verify that the employees actually understand what they were trained for

    2009-01-01

    The physical security of facilities containing radioactive objects, an already important matter, now has a new aggravating factor: the existence of groups intending to obtain radioactive materials for the purpose of intentionally induce radioactive contamination incidents, as for example the explosion of dirty bombs in populated regions, damaging both people and environment. In this context, the physical security of such facilities must be reinforced so to reduce the possibilities of such incidents. This paper presents a adapted game engine used as a virtual reality system, enabling the modeling and simulation of scenarios of nuclear facilities containing radioactive objects. In these scenarios, the physical protection barriers, as fences and walls, are simulated along with vigilance screens. Using a computer network, several users can participate simultaneously in the simulation, being represented by avatars. Users can play the roles of both invaders and security staff. The invaders have as objective to surpass the facility's physical protection barriers to steal radioactive objects and flee. The security staff have as objective to prevent and stop the theft of radioactive objects from the facility. The system can be used to analysis simulated scenarios and train vigilance/security staff. A test scenario was already developed and used, and the preliminary tests had satisfactory results, as they enabled the evaluation of the physical protection barriers of the virtual facility, and the training of those who participated in the simulations in the functions of a security staff.

    Adaptive features of innate immunity, also termed 'trained immunity', have recently been shown to characterize monocytes of BCG vaccinated healthy volunteers. Trained immunity leads to increased cytokine production in response to non-related pathogens via epigenetic reprogramming of monocytes. Recently, memory-like properties were also observed in NK cells during viral infections, but it is unknown if memory properties of NK cells contribute to trained immunity due to BCG vaccination. BCG vaccination of healthy volunteers increased proinflammatory cytokine production following ex vivo stimulation of NK cells with mycobacteria and other unrelated pathogens up until at least three months after vaccination. In addition, in a murine model of disseminated candidiasis, BCG vaccination led to an increased survival in SCID mice, which was partially dependent on NK cells. These findings suggest that NK cells may contribute to the non-specific (heterologous) beneficial effects of BCG vaccination. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of this paper was to assess the efficacy of process-based cognitive training (pb-CT) combined with reminiscence therapy (RT) in patients with mild Alzheimer's disease (mAD) and mild cognitive impairment (MCI) and in healthy elderly (HE) subjects. This multicenter, randomized, controlled trial involved 348 participants with mAD, MCI, and HE from four European countries. Participants were randomly assigned to two arms of a crossover design: those in arm A underwent 3 months of computerized pb-CT for memory and executive functions combined with RT and 3 months of rest; those in arm B underwent the reverse. The primary outcome was the effect of the training on memory and executive functions performance. The secondary outcome was the effect of the training on functional abilities in mAD assessed with the instrumental activities of daily living. We found a significant effect of the training for memory in all three groups on delayed recall of the Rey Auditory Verbal Learning Test and for executive functions in HE on the phonological fluency test. MCI and HE participants maintained these effects at follow-up. MCI and mAD participants also showed a significant effect of the training on the Mini-mental state examination scale. Participants with mAD showed more stable instrumental activities of daily living during the training versus the rest period. Our results corroborate the positive effect of pb-CT and its maintenance primarily on memory in HE and MCI participants that did not seem to be potentiated by RT. Moreover, our results are very promising for the mAD participants. Copyright © 2015 John Wiley & Sons, Ltd.

    educational problems in area of nuclear materials physical protection, control and accountability (MPC and A) in Russia. General scheme of Russian educational system is considered with main emphasis on the directions under implementation now, namely academic training system, re-training system and specialists qualification upgrade system in MPC and A area. Russian academic training system consists of the educational programs at various levels: Bachelor of Sciences, Master of Sciences, Specialist (also referred to as an Engineer Degree), and professional re-training of the personnel already working in the nuclear field. Currently, only the Master of Sciences Graduate Program is completely developed for the students training. This is taking place at Moscow Engineering Physics Institute (State University, MEPhI), where the fourth generation of Masters has graduated from in May 2003. The graduates are now working at nuclear-related governmental agencies, non-governmental organizations, universities, and nuclear facilities. Development of the system to produce academically trained Russian MPC and A personnel is therefore well underway. MEPhI's MPC and A Engineering Degree Program which currently under development is considered in the paper. Analysis of MPC and A needs at Russian nuclear facilities has demonstrated the Engineering Degree Program is the best way to satisfy these needs and the resulting demands for MPC and A specialists at Russian nuclear enterprises. This paper discusses specific features of the Engineering Degree training required by Russian education legislation and the Russian system of quality control as applied to the training process. The paper summarizes the main joint actions undertaken during the past three years by MEPhI in collaboration with the US Department of Energy and US national laboratories to develop the MPC and A Engineering Degree Program in Russia. These actions include opening a new Engineering Degree specialty, Safeguards and Nonproliferation

    Full Text Available Many active ingredients extracted from herbal and medicinal plants are extensively studied for their beneficial effects. Antioxidant activity and free radical scavenging properties of thymoquinone (TQ have been reported. The present study evaluated the possible protective effects of TQ against the toxicity and oxidative stress of sodium fluoride (NaF in the liver of rats. Rats were divided into four groups, the first group served as the control group and was administered distilled water whereas the NaF group received NaF orally at a dose of 10 mg/kg for 4 weeks, TQ group was administered TQ orally at a dose of 10 mg/kg for 5 weeks, and the NaF-TQ group was first given TQ for 1 week and was secondly administered 10 mg/kg/day NaF in association with 10 mg/kg TQ for 4 weeks. Rats intoxicated with NaF showed a significant increase in lipid peroxidation whereas the level of reduced glutathione (GSH and the activity of superoxide dismutase (SOD, catalase (CAT, glutathione S-transferase (GST and glutathione peroxidase (GPx were reduced in hepatic tissues. The proper functioning of the liver was also disrupted as indicated by alterations in the measured liver function indices and biochemical parameters. TQ supplementation counteracted the NaF-induced hepatotoxicity probably due to its strong antioxidant activity. In conclusion, the results obtained clearly indicated the role of oxidative stress in the induction of NaF toxicity and suggested hepatoprotective effects of TQ against the toxicity of fluoride compounds.

    Purpose: To evaluate the possibilities of Internet-based radiation protection training among referring physicians. Material and Methods: 324 referring physicians underwent an Internet-based radiation protection training course (www.prewise.com/radiationsafetytraining). Two hundred ten of them (96 female, 114 male, aged 25-64 years) filled out the questionnaire, which included questions regarding their expectations for the course, its scope and schedule, and the benefit they derived from the course. In addition, we asked whether it was difficult to learn using the Internet, whether e-learning saved time, and whether they learned more or less effectively in comparison to conventional lectures. Results: 75% found e-learning to be an easy way to study. Nineteen percent had previous experience in e-learning. Sixty-one percent found that it saved time, and 57% stated that they learned more effectively using e-learning in comparison to conventional lectures (22% chose 'could not say'). Ninety-one percent found that the course fulfilled their expectations, and the scope and schedule were found convenient by 91% and 55% of subjects, respectively. Eighty-four percent stated that they benefited from the course, and 94% were willing to study using the Internet in the future. No sex or age differences were found. Subjects working in the open ward (P 0.028) and hospital (P 0.004) found the course to be more timesaving than subjects working elsewhere. Conclusion: Finnish medical doctors are very positive about Internet-based learning. E-learning seems to be a well-accepted and practical learning method in healthcare

    With the proximity of the events of the Olympic Games, Brazil can become a great place of visibility for running dirty bombs or any other radiation mode proliferation by terrorists. Aware of these problems, the government and the organizations created managements of emergencies to ensure that these events elapse in an orderly and safe manner. The management of emergency situations at an event is a complex problem, which involves dynamic, unforeseen and unintended situations, emphasizing the potential complexity of the contexts in which organizations operate and, as a consequence, the people involved in the execution of multiple tasks from activities that require intense cognitive effort, are often challenged to adapt dynamically to maintain the productivity of the organization at satisfactory levels of performance usually impedes these people reflect on the results of their actions and learn from them. Therefore, it is extremely important to create tools that address the methods and techniques of Cognitive Task Analysis (CTA) to assist in the previous training of the security agents, for example, detection and approaches of people who carry radioactive elements. One of the possible ways to accomplish this training is through the use of virtual reality. Virtual environments bring some advantages like reducing costs and risks. The aim of this paper is to present a virtual simulator to evaluate the use in training agents in major events. As a case study, the Maracana and the agents of the National Nuclear Energy Commission (CNEN) was chosen. (author)

    Education in Radiation Protection (RP) should be part of the medicine curriculum, in accordance with the recommendations of the Directive 97/43/EURATOM and Report 116 of the European Commission. The propose of this paper is to show the current situation of the Radiation Protection teaching at the Schools of Medicine in Spain. 27 Spanish Schools of Medicine have been revised. Only in the Cantabria University, the PR constitutes an obligatory subject. In the other Universities, the PR subject appears as an optional matter with 3 to 5 credits. There is disparity among the educational contents on PR that are imparted in the Medicine Degree of the Spanish Schools. We propose the following recommendations: To define the educational objectives accurately, looking for a real interest for any medical student; to unify the contents and programs in the different study plans, and to elaborate an appropriate educational material, including practical cases that facilitate learning.

    Education plays an important role in emergency management to prepare members of all levels of management for the worst case scenario. The mission that organizations have to deal with, is based on the application of fundamental knowledge, accumulated know-how and knowledge of the intersections and abilities of the participating organizations. An effective, safe and resource-saving way to get effective help in preparing disasters are table-top trainings. What great warlords helped to win centuries ago, is now increasingly anchored on a statutory basis and introduced in the emergency planning. (orig.)

    Iberdrola Ingenieria y Consultoria (Iberinco) has developed some computer applications based in New Technologies, Virtual Reality and Multimedia, with the aim to optimise the formation and training of professionally exposed workers as well as to inform the public. The use of the new technologies could be an important help for the workers training. Virtual Reality Projects developed by Iberinco are: a) CIPRES: Interactive Calculations of Radiological Protection in a Simulation Environmental and, b) ACEWO: Workers Control Access to Nuclear Power Plants, virtual Reality could be directly applicable to several aspects related with Radiological Protection Training, for example. An application that workers could used to learn the main aspects of Radiological Protection related with: a) Physical concepts, b) Regulations, c) Use of protective clothing, d) Access into and exit out controlled areas, e) ALARA criterion. An examples is the project ACEWO. A training program based on Virtual Reality systems with simulations of procedures in which the operators could receive high doses. In this way, the operation time and dose could be minimised according to the ALARA criterion owing to the ability of repeating the exercise, or the work, as many times as be necessary, like project CIPRES. Iberinco has been developed an educational CD multimedia on nuclear energy and the protection measures foreseen in the emergency plans for the Spanish Civil Protection Agency, with the aim of being distributed to all the schools placed near a nuclear power plant.

    The astronauts have to spend more time in space and the colonization of the moon and Mars are in the cross hairs of international agencies. The cosmic radiation from which we are protected on ground by atmosphere and by the terrestrial magnetosphere (.4 mSv/year according to Who) become really threatening since 20 km altitude, delivering an average radiation dose of a therapeutic kind to astronauts with peaks related to solar events. It is composed in majority of hadrons: protons (85%) and heavy ions (13%), but also photons (2%) of high energy (GeV/n)). the incurred risks are multiple: early ones(cataract, central nervous system damages, whole body irradiation) but especially delayed ones (carcinogenesis). The astronauts radiation protection turns poor and the rate of death risk by cancer returning from a mission on Mars has been estimated at 5%. The Nasa created in 2004 a summer school aiming to awareness young researchers to the space radiobiology specificities. Areas concerned as follow: radioinduced DNA damage and repair, cell cycle, apoptosis, bystander effect, genome instability, neuro degeneration, delayed effects and carcinogenesis in relation with radiation exposure.

    Developing organisms have the ability to cope with environmental demands through physiologic and morphologic adaptations. Early life malnutrition has been recognized as an environmental stimulus that is related with down-regulation of immune responses. Some of these effects are explained by the epigenetics and the programming of hormones and cytokines impairing the modulation of the immune cells in response to environmental stimuli. Recently, it has been demonstrated that these effects are not deterministic and current environment, such as physical activity, can positively influence the immune system. Here, we discuss the effects of perinatal malnutrition on the immune system and how it can be modulated by physical training. The mechanism includes the normalization of some hormones concentrations related to growth and metabolism such as leptin, IGF-1 and glucocorticoids. Copyright AULA MEDICA EDICIONES 2014.

    From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

    Radiation Protection should be included in the programme of studies necessary to confer a bachelor's degree in Medicine, according to the Directive 97/43 Euratom on medical exposures and the Report RP116 published by the European commission on Education and Training in radiation protection for medical exposures. To analyse the present training programmes in radiation protection at the Medical School in different Spanish Universities. The syllabus and the contents of the subjects including radiation protection issues in 27 Spanish Schools of Medicine have been revised. Radiation protection subjects are obligatory at present, only at the Schools of Medicine from Cantabria and Malaga. There is a group of Schools of Medicine where radiation protection is an optional matter with an extension of 4,5 credits (45 hours). It also exists some topics in radiation protection in subjects dealing with Medical Physics and General Radiology (with a range value from 1 to 10 hours), in 10 Schools of Medicine. A wide dispersion among the contents of different subjects and the hours of training allocated by the different School are found. It should be useful the harmonization of the programmes. (Author)

    The companies that are working in maintenance, decontamination, dismantling and assessment in nuclear power plants, usually have their employees in different facilities far from its central offices. When there is a training in radiological protection applied to the nuclear field, it is difficult for these people the attendance to the course because of different reasons. One of them is the location of the formation centres which sometimes are not near from the nuclear facilities, so it is necessary the displacement of the employees, and the time in displacements to the formation centre and costs increase exponentially. In addition if they go to the courses they usually cannot attend their daily work with the same effectiveness depending on the duration of the course. In this work we present a technological platform that is designed in collaboration with the university of give different courses related with radiological field applied to nuclear and radioactive facilities. This platform is adapted and designed to different contents depending on the course. At the main screen we have included and index and announces of the course, so we have arranged the contents in different areas and sections. When the student finishes an area, an evaluation has to be done to prove the understanding of the lessons. We have included films of different activities as decontamination devices, radiation detectors, etc. with the contents to make the explanations more understandable to the student. The student can access to this platform with private password and follow the course individually. The course is complemented with a final review and exam that are not online to guarantee that the training is well finished. This type of training is more flexitime and can be adapted to the necessities of each user, avoiding high costs and unnecessary displacements. (Author)

    Full Text Available Procedural modeling has proven to be a very valuable tool in the field of architecture. In the last few years, research has soared to automatically create procedural models from images. However, current algorithms for this process of inverse procedural modeling rely on the assumption that the building style is known. So far, the determination of the building style has remained a manual task. In this paper, we propose an algorithm which automates this process through classification of architectural styles from facade images. Our classifier first identifies the images containing buildings, then separates individual facades within an image and determines the building style. This information could then be used to initialize the building reconstruction process. We have trained our classifier to distinguish between several distinct architectural styles, namely Flemish Renaissance, Haussmannian and Neoclassical. Finally, we demonstrate our approach on various street-side images.

    The introduction of 3D analysis of the puborectalis muscle, for diagnostic purposes, into daily practice is hindered by the need for appropriate training of the observers. Automatic 3D segmentation of the puborectalis muscle in 3D transperineal ultrasound may aid to its adaption in clinical practice. A manual 3D segmentation protocol was developed to segment the puborectalis muscle. The data of 20 women, in their first trimester of pregnancy, was used to validate the reproducibility of this protocol. For automatic segmentation, active appearance models of the puborectalis muscle were developed. Those models were trained using manual segmentation data of 50 women. The performance of both manual and automatic segmentation was analyzed by measuring the overlap and distance between the segmentations. Also, the interclass correlation coefficients and their 95% confidence intervals were determined for mean echogenicity and volume of the puborectalis muscle. The ICC values of mean echogenicity (0.968-0.991) and volume (0.626-0.910) are good to very good for both automatic and manual segmentation. The results of overlap and distance for manual segmentation are as expected, showing only few pixels (2-3) mismatch on average and a reasonable overlap. Based on overlap and distance 5 mismatches in automatic segmentation were detected, resulting in an automatic segmentation a success rate of 90%. In conclusion, this study presents a reliable manual and automatic 3D segmentation of the puborectalis muscle. This will facilitate future investigation of the puborectalis muscle. It also allows for reliable measurements of clinically potentially valuable parameters like mean echogenicity. This article is protected by copyright. All rights reserved.

    Clinical narratives, such as radiology and pathology reports, are commonly available in electronic form. However, they are also commonly entered and stored as free text. Knowledge of the structure of clinical narratives is necessary for enhancing the productivity of healthcare departments and facilitating research. This study attempts to automatically segment medical reports into semantic sections. Our goal is to develop a robust and scalable medical report segmentation system requiring minimum user input for efficient retrieval and extraction of information from free-text clinical narratives. Hand-crafted rules were used to automatically identify a high-confidence training set. This automatically created training dataset was later used to develop metrics and an algorithm that determines the semantic structure of the medical reports. A word-vector cosine similarity metric combined with several heuristics was used to classify each report sentence into one of several pre-defined semantic sections. This baseline algorithm achieved 79% accuracy. A Support Vector Machine (SVM) classifier trained on additional formatting and contextual features was able to achieve 90% accuracy. Plans for future work include developing a configurable system that could accommodate various medical report formatting and content standards.

    This paper addresses the problem of classifying minerals common in siliciclastic and carbonate rocks. Twelve chemical elements are mapped from thin sections by energy dispersive spectroscopy in a scanning electron microscope (SEM). Extensions to traditional multivariate statistical methods...... are applied to perform the classification. First, training and validation sets are grown from one or a few seed points by a method that ensures spatial and spectral closeness of observations. Spectral closeness is obtained by excluding observations that have high Mahalanobis distances to the training class......–Matusita distance and the posterior probability of a class mean being classified as another class. Fourth, the actual classification is carried out based on four supervised classifiers all assuming multinormal distributions: simple quadratic, a contextual quadratic, and two hierarchical quadratic classifiers...

    According to the Public Health Code, all the professionals who perform therapeutic or diagnostic acts with ionizing radiation (IR) and the professionals involved in the implementation of these acts and the maintenance of the equipment should be given theoretical and practical training. Such training must focus on the protection of the people exposed to IR for medical purposes. Knowledge should be updated at least every 10 years, under the Nuclear Safety Authority. For the Ministry of Defense, the Military School of the Val-de-Grace offers a training day dedicated to the health-care professionals of the Military Hospitals and the forces using or prescribing examinations requiring ionizing radiation. The objective of the study was to assess the efficiency of this training day on patients' radiation protection organized for the French Armed Forces Health Service; the study was carried out with questionnaires assessing the knowledge and the quality of the interventions. A multicentric prospective study was conducted from September 2013 to November 2014 in four Military Hospitals (Val-de- Grace, St. Anne, Percy and Legouest) on French Armed Forces Health Service professionals who agreed to answer a questionnaire containing 50 multiple choice questions, both at the beginning and at the end of the training day. The analysis was focused on the comparison of the scores obtained before and after the training (overall ratings, by profession and according to the monitoring of previous training or not). The results of the primary care physicians' questionnaires were of particular interest (physicians serving in military units). The results were obtained from a total of 126 respondents over five training sessions in the four Military Hospitals. A significant 18% increase of the overall score after training according to the Student's test with p < 0.001 was observed. However, there was no significant difference between the results obtained by the professionals who

    The LHC makes use of a collimation system to protect its sensitive equipment by intercepting potentially dangerous beam halo particles. The appropriate collimator settings to protect the machine against beam losses relies on a very precise alignment of all the collimators with respect to the beam. The beam center at each collimator is then found by touching the beam halo using an alignment procedure. Until now, in order to determine whether a collimator is aligned with the beam or not, a user is required to follow the collimator’s BLM loss data and detect spikes. A machine learning (ML) model was trained in order to automatically recognize spikes when a collimator is aligned. The model was loosely integrated with the alignment implementation to determine the classification performance and reliability, without effecting the alignment process itself. The model was tested on a number of collimators during this MD and the machine learning was able to output the classifications in real-time.

    In order to keeping personnel doses as low as reasonably achievable, and also to help satisfy requirements of NRC regulations contained in 10 CFR 19, a training program was established to qualify all individuals prior to their use of the OSTR PT systems. Program objectives are directed mainly towards minimizing the spread of radioactive contamination and reducing the potential for unnecessary and inappropriate personnel radiation exposure; however, other operational and emergency procedures are also covered. The PT systems training program described in this report was established approximately 8 to 10 years ago but recently there was an increased interest to use it. Whether or not a PT system training program should be implemented at a specific TRIGA operation (assuming the facility is equipped with a PT system) will undoubtedly be influenced heavily by the nature and frequency of the PT system's use, by who uses the system, and by whether the system is one of the automatic loading and unloading types, or one of the more' commonly encountered manually operated systems. However, from our experience we feel that training commensurate with the type of PT system operation being conducted is a wise investment, and should be a requirement for all system operators

    The aim of this research was to know the protective and risk factors associated with voice strain in teachers. A total of 675 teachers from Castille and León, Spain took part in the research within an age range between 23 and 66 years (from nursery school to university). A cross-sectional, descriptive, and analytic design was applied to data from a self-administered questionnaire. The research showed that 16.4% had suffered some voice disorder and a remarkable percentage had never received any kind of voice training. The bivariate and multivariate analyses show that the size of the classroom, being a primary school teacher, teaching physical education, the noise caused by the students in the classroom, the struggle to keep the order within the class, raising the voice, and bad sleep are risk factors in the voice disorders. Each learning stage features a different risk factor, namely in nursery school, the noise caused by the pupils; in primary education, raising the voice; and in secondary education, the struggle to keep the order within the class. All these risk factors are linked with each other. The preventive measures must provide adequate answers to the voice requirements for every subject and stage, and these preventive measures must be based on the educational psychology principles to help the teachers deal with the problems originated by the lack of authority or the noise made by the students, using the proper voice techniques.

  19. Report of the work-group derived from the permanent radioprotection expert Group on the desirable evolutions for the functions and training of persons with expertise in radiation protection

    International Nuclear Information System (INIS)

    2010-01-01

    This report first discusses the issues of training in radiation protection within the French national context by distinguishing training in relationship with workers' radiation protection (internal training in radiation protection as foreseen in the French Work Code, training in the industrial field, training in the field of radioactive material transportation, training of the person with expertise in radiation protection or PCR), and training in relationship with patient radiation protection (training of the person specialised in medical radio-physics, training in patient radiation protection). It describes the situation and evolution perspectives at the European level by addressing the situation in different countries (Great-Britain, Belgium, Switzerland), the content of the 96/29/Euratom directive, the current evolutions in Europe (European platform EUTERP, European programs ENETRAP, transposition of the 2006-123-CE directive, the 2005-36-CE directive and its revision), and some international aspects. The authors discuss strengths and weaknesses of the person with expertise in radiation protection (PCR), and state reflections and recommendations regarding the evolution of the present PCR arrangement

    Training and information in the radiation protection subject is a legal mandatory as well as an essential tool for the optimisation and quality of the procedures. Accounting for the relevance of the dose to the population due to medical exposures, it seems obvious the necessity of improving this subject in order to design a feasible and efficient strategy. The importance of learning to communicate and to manage on the one hand an excessive perception of the risk to low doses in comparison with other agents, that could be made extensible for judges, lawyers and media, and on the other hand, the relevant doses due to interventional procedures, to TC studies, etc, is one of the basic commitment of a Radiation Protection Service. This paper summarises: - The contents of international recommendations, the European Directives and Spanish legislation related to this topic. - The strategy of training and information to the levels indicated, from the point of view of a referential Radiation Protection Service for a Teaching Hospital and its area associated os specialized attention and primary attention. We can not forget on-going training for owner workers. - The contents of the informative leaflets. (Author) 13 refs

    Most behaviors unfold in time and include a sequence of submovements or cognitive activities. In addition, most behaviors are automatic and repeated daily throughout life. Yet, relatively little is known about the neurobiology of automatic sequence production. Past research suggests a gradual transfer from the associative striatum to the sensorimotor striatum, but a number of more recent studies challenge this role of the BG in automatic sequence production. In this article, we propose a new neurocomputational model of automatic sequence production in which the main role of the BG is to train cortical-cortical connections within the premotor areas that are responsible for automatic sequence production. The new model is used to simulate four different data sets from human and nonhuman animals, including (1) behavioral data (e.g., RTs), (2) electrophysiology data (e.g., single-neuron recordings), (3) macrostructure data (e.g., TMS), and (4) neurological circuit data (e.g., inactivation studies). We conclude with a comparison of the new model with existing models of automatic sequence production and discuss a possible new role for the BG in automaticity and its implication for Parkinson's disease.

    A radiation protection pilot course using Information and Communication Technologies (ICTs) and cooperative tools has been proposed to students at Master level, MSc in Radiation Protection. The objectives and purposes are to introduce ICTs in order to improve the Education and Training (E and T) in Radiation Protection by facilitating the access to resources and services, and the exchanges and collaborative work between learners and teachers. The use of Open and Distance Learning (ODL) is one of the means to ensure the future supply of appropriately educated and skilled personnel for those who use ionising radiations across Europe and secondly, to meet the increasing demand and decreasing number of Radiation Protection Experts available in Europe. Open and Distance Learning contributes by promoting mobility of workers and students throughout the European countries. Assessment of this pilot course points out the benefits and inconveniences of such pedagogical approach in the Radiation Protection domain. This new approach has been considered attractive and efficient by students for specific topics. Students feel more involved in their own training by learning topics whenever they want, at their own pace. Concerning the content, an improvement has to be implemented by integrating Rich Media contents, and a more efficient track of each students knowledge by a tutor. Full complete distance learning seems not to be the best way, because students need to exchange in a face to face environment, with teachers, lecturers and tutors. A blended learning (b-Learning) is preferred by proposing various pedagogical sequences such as face to face, e-Learning, case studies and simulation activities. E-Learning or b-Learning can contribute to the capitalization of already existing good practices in the field of occupational, public and medical exposures. This pedagogical approach will be integrated in a part of the future European Master degree in Radiation Protection which starts in

    Aging of attentiveness affects cognitive functions like perception and working memory, which can seriously impact communication between dogs and humans, potentially hindering training and cooperation. Previous studies have revealed that aged laboratory beagles and pet Border collies (BC) show a decline in selective attention. However, much less is known about the aging of attentiveness in pet dogs in general rather than in specific breeds. Using 185 pet dogs (75 BC and 110 dogs of other breeds) divided into three age groups [late adulthood (6- dogs in order to explore if prior results in BC are generalizable and to evaluate the influence of lifelong training on measures of attention. Each dog’s lifelong training score (ranging from 0 to 52) was calculated from a questionnaire filled in by the owners listing what kinds of training the dog participated in during its entire life. Dogs were tested in two tasks; the first, measuring attentional capture and sustained attention toward two stimuli (toy and human); and the second, measuring selective attention by means of clicker training for eye contact and finding food on the floor. In the first task, results revealed a significant effect of age but no effect of lifelong training on latency to orient to the stimuli. Duration of looking decreased with age and increased with lifelong training. In the second task, while lifelong training decreased the latency of dogs to form eye contact, aged dogs needed longer to find food. BC did not differ from other dogs in any measures of attention except latency to find food. In conclusion, aged dogs showed a decline in attentional capture and sustained attention demonstrating that these tests are sensitive to detect aging of attentiveness in older pet dogs. Importantly, selective attention remained unchanged with age and lifelong training seemed to delay or reduce the aging of attentiveness, further highlighting the importance of lifelong training in retaining general cognitive

    There is no possibility in Germany to serve an apprenticeship in practical radiation protection in nuclear facilities. However, the scope of knowledge required for such activities is defined in a binding 'Directive about Ensuring the Knowledge Required in Persons otherwise Engaged in the Operation of Nuclear Power Plants'. That Directive by far exceeds the scope, in terms of safety, normally applied to a vocation or activity. The Directive implicitly contains three important provisions: Plant operators must ensure that radiation protection workers have all the knowledge they need to do their job safely; that radiation protection workers are autonomous, within certain limits, as a consequence of the depth of knowledge they have; that radiation protection workers are given formal advanced training possibilities. An examination to be taken by radiation protection workers before a Chamber of Industry and Commerce was introduced in 1982 in order to make available personnel trained in the whole range of possible activities as defined in the Directive referred to above. However, persons who have passed the exam before a Chamber of Commerce and Industry no longer automatically fulfill the criteria under the Directive after three years, but must undergo advanced training in a formal program.

  14. A conservative bound for the probability of failure of a 1-out-of-2 protection system with one hardware-only and one software-based protection train

    Redundancy and diversity have long been used as means to obtain high reliability in critical systems. While it is easy to show that, say, a 1-out-of-2 diverse system will be more reliable than each of its two individual “trains”, assessing the actual reliability of such systems can be difficult because the trains cannot be assumed to fail independently. If we cannot claim independence of train failures, the computation of system reliability is difficult, because we would need to know the probability of failure on demand (pfd) for every possible demand. These are unlikely to be known in the case of software. Claims for software often concern its marginalpfd, i.e. average across all possible demands. In this paper we consider the case of a 1-out-of-2 safety protection system in which one train contains software (and hardware), and the other train contains only hardware equipment. We show that a useful upper (i.e. conservative) bound can be obtained for the system pfd using only the unconditional pfd for software together with information about the variation of hardware failure probability across demands, which is likely to be known or estimatable. The worst-case result is obtained by “allocating” software failure probability among demand “classes” so as to maximize system pfd

    Exchange visits offer a bundle of benefits, well beyond just acquiring information. The value of exchange visits of stakeholders in the education and training processes in the area of radiation protection and safety culture is demonstrated on the activities performed within the EC projects NERIS-TP and PREPARE under the umbrella of the European NERIS Platform. The technical visits to the affected regions of Belarus close to Chernobyl NPP as well as Fukushima Mission 2013 on the FAIRDO and ISAP 2013 in Japan illustrate well the methods of wide range of stakeholders engagement and involvement in the area of radiation control and practical radiological culture and their benefit in the education and training process. These visits have created common understanding, relationships forged in the hardships of shared experience, commitments to new approaches, and friendships as foundation for future networking. Technical visits allowed Slovak stakeholders and Belorussian hosts to focus time and attention on a topic, learning deeply, sharing ideas, and assessing the relevance of new approaches in the area of the post-accident management and rehabilitation with the main goal of improvement both national and local plans for preparedness and recovery. The technical or study visits for education and training purpose are valuable in the process of enhancement of the radiation protection and safely culture. (authors)

Assessment of this pilot course points out the benefits and inconveniences of such pedagogical approach in the Radiation Protection domain. This new approach has been considered attractive and efficient by students for topics such as radioactivity, interaction of radiation with matter. Students feel more involved in their own training by learning topics whenever they want, at their own rhythm. Concerning the content, an improvement has to be implemented by integrating Rich Media contents (video, sound, simulation, flash animation) and a more efficient track of the knowledge by a tutor.

    Cervical cancer is known as one of the most prevalent types of cancers and a major public health problem in developing countries which can be detected by Pap test, prevented, and treated. Despite the effective role of Pap test in decreasing the incidence and mortality due to cervical cancer, it is still one the most common causes of cancer-related deaths among women, especially in developing countries. Thus, this study aimed to examine the effect of educational interventions implemented by health volunteers based on protection motivation theory (PMT) on promoting Pap test use among women. This quasi-experimental study was conducted on 60 health volunteers and 420 women. The study participants were divided into an intervention and a control group. Data were collected using a valid self-reported questionnaire including demographic variables and PMT constructs which was completed by both groups before and 2 months after the intervention. Then, the data were entered into the SPSS statistical software, version 19 and were analyzed using Chi-square test, independent T-test, and descriptive statistical methods. PPap test use also increased by about 62.9% among the study women. This study showed a significant positive relationship between PMT-based training and Pap test use. The results also revealed the successful contribution of health volunteers to training cervical cancer screening. Thus, training interventions based on PMT are suggested to be designed and implemented and health volunteers are recommended to be employed for educational purposes and promoting the community's, especially women's, health.

    The establishment of an inter departmental project, financed by the Spanish Ministry of Education, has made possible the development to specific didactic materials on Radiological Protection and Quality Assurance in Medical Radiodiagnostic Practices. These have been published as a manual and practical notebook. This material constitutes the grounding work for the first continuous tele-education training course via Internet that Spanish professionals exposed to ionising radiation are following. Interactive multimedia training and tele-education may become one of the alternatives that allow health science professionals to receive continuous training, provided that adequate content and aims had been established during undergraduate training.

  18. Training for instructor in radiation protection courses in the medical diagnosis with X-Rays in Mexico; Formaacion de instructores para cursos de proteccion raidologica en el diagnostico medico con rayos X en Mexico

    2003-07-01

    The General Regulation of Radiological Security establishes in its article 159 that the occupationally exposed professionals will have to count on the authorization of the National Commission of Nuclear Security and Safety (CNSNS) with respect to their training. The Mexican official norm NOM-157-SSA1-1996: Protection and radiological safety in the medical diagnosis with X-rays, indicates that the personnel must receive and accept the information, instructions and training related to the protection and radiological safety, in order to accomplish their work according to the requirements and obligations established in the outstanding procedures. Therefore it was designed an initial training course of instructors in the field of the radiological protection to train occupationally exposed professionals who work in the medical diagnosis establishments with X-rays. The didactic material was elaborated considering a period of training of 10 working days, 8.0 daily hours considering theoretical topics, as well as 11 practical. It is used a conventional radiology equipment, a ionization chamber of brand INOVISIOB model 451 P-DE-SI for increasing the radiation levels, and equipment Radical model 9015 with two ionization chambers of 150 cc and 150 cc respectively, as well as a calibrated plates game of aluminium type 110 and a phantom of acrylic as disperser. To date 73 persons have been trained, from which only 37% approved the initial training course. It has been seen that it is necessary to count on a previous training in the filed of the radiological protection to better profit from this training, since if students do not have good bases it is not possible for them to learn all the content in only 80 hours. To date it has been trained to 73 persons, of alone those which 37.0% approved the initial. (Author)

    Full text: In expert training on physical protection of nuclear materials (NMPP) an educational and laboratory base has special importance. In these laboratories the students receive practical skills concerning physical protection systems (PPS). The basic requirements for creating such base are formulated in a certain educational program implemented at an educational institution. Thus it is necessary to take into account the following features of a modern nuclear object PPS: restriction of an object visiting with the purpose of acquaintance with features of a certain object PPS; dynamical change of PPS component nomenclature; increase of use of computer facilities for managing all PPS subsystems; increase of integration degree of separate subsystems in a uniform PPS complex; high cost of PPS components. Taking that into consideration a university, which assumes to begin the expert training on NMPP, is compelled to solve the following tasks: creation of its own laboratory base. The implementation of practical occupations with visiting a nuclear object cannot be executed practically; definition of quantity and structure of educational laboratories. Thus the features of the implemented educational plan should be taken into account in addition; optimization of expenses on laboratory creation. The regular updating of laboratory equipment structure is impossible in a practical manner. Therefore unique correct decision is to supply laboratories with the equipment, which uses the typical technological decisions on performing the basic PPS functions (detection, delay, estimation of a situation, neutralization); development of laboratory work conducting procedures (laboratory practical works); technical support of the created laboratories. The certain experience of solving the listed tasks is accumulated at the Moscow Engineering Physics Institute (State University) (MEPhl) while implementing 'Physical Protection, Control and Accountability of Nuclear Materials' master

    Full Text Available This study investigated the effects of long-term simulated weightlessness on liver morphology, enzymes, glycogen, and apoptosis related proteins by using two-month rat-tail suspension model (TS, and liver injury improvement by rat-tail suspension with resistance training model (TS&RT. Microscopically the livers of TS rats showed massive granular degeneration, chronic inflammation, and portal fibrosis. Mitochondrial and endoplasmic reticulum swelling and loss of membrane integrity were observed by transmission electron microscopy (TEM. The similar, but milder, morphological changes were observed in the livers of TS&RT rats. Serum biochemistry analysis revealed that the levels of alanine aminotransferase (ALT and aspartate aminotransferase (AST were significantly higher (p<0.05 in TS rats than in controls. The levels of ALT and AST in TS&RT rats were slightly lower than in RT rats, but they were insignificantly higher than in controls. However, both TS and TS&RT rats had significantly lower levels (p<0.05 of serum glucose and hepatic glycogen than in controls. Immunohistochemistry demonstrated that the expressions of Bax, Bcl-2, and active caspase-3 were higher in TS rats than in TS&RT and control rats. Real-time polymerase chain reaction (real-time PCR showed that TS rats had higher mRNA levels (P < 0.05 of glucose-regulated protein 78 (GRP78 and caspase-12 transcription than in control rats; whereas mRNA expressions of C/EBP homologous protein (CHOP and c-Jun N-terminal kinase (JNK were slightly higher in TS rats. TS&RT rats showed no significant differences of above 4 mRNAs compared with the control group. Our results demonstrated that long-term weightlessness caused hepatic injury, and may trigger hepatic apoptosis. Resistance training slightly improved hepatic damage.

    This study sought to determine the role of physical training (PT) on body weight (BW), energy balance, histological markers of nonalcoholic fatty liver disease (NAFLD) and metabolic gene expression in the liver of ob/ob mice. Adult male ob/ob mice were assigned into groups sedentary (S; n = 8) and trained (T; n = 9). PT consisted in running sessions of 60 min at 60% of maximal speed conducted five days per week for eight weeks. BW of S group was higher from the 4(th) to 8(th) week of PT compared to their own BW at the beginning of the experiment. PT decreased daily food intake and increased resting oxygen consumption and energy expenditure in T group. No difference was observed in respiratory exchange ratio, but the rates of carbohydrate and lipids oxidation, and maximal running capacity were greater in T than S group. Both groups showed liver steatosis but not inflammation. PT increased CPT1a and SREBP1c mRNA expression in T group, but did not change MTP, PPAR-α, PPAR-γ, and NFKB mRNA expression. In conclusion, PT prevented body weight gain in ob/ob mice by inducing negative energy balance and increased physical exercise tolerance. However, PT did not change inflammatory gene expression and failed to prevent liver steatosis possible due to an upregulation in the expression of SREBP1c transcription factor. These findings reveal that PT has positive effect on body weight control but not in the liver steatosis in a leptin deficiency condition.

Concentrated animal feeding operations (CAFOs are growing in number throughout the country. This pilot study explores the perception of risk, receipt of work-related training, provision and usage of personal protective equipment (PPE, and prevention preferences of Latino immigrant hog CAFO workers in Missouri. Forty workers (M age = 36.08 years, SD = 10.04; 92.5% male; 70.0% Mexican were interviewed. Results indicate that most workers did not perceive their job as dangerous. Limited English proficient workers were significantly less likely to report receiving any work-related training. Although most workers had access to employer provided PPE, usage was inconsistent. As the demographic composition of the farmworker population in the Midwest becomes increasingly comprised of hired immigrant workers, it will be imperative to develop occupational safety and health educational and outreach efforts focused on the needs of these workers.

  13. Study of histopathological and molecular changes of rat kidney under simulated weightlessness and resistance training protective effect.

    Directory of Open Access Journals (Sweden)

    Ye Ding

    Full Text Available To explore the effects of long-term weightlessness on the renal tissue, we used the two months tail suspension model to simulate microgravity and investigated the simulated microgravity on the renal morphological damages and related molecular mechanisms. The microscopic examination of tissue structure and ultrastructure was carried out for histopathological changes of renal tissue morphology. The immunohistochemistry, real-time PCR and Western blot were performed to explore the molecular mechanisms associated the observations. Hematoxylin and eosin (HE staining showed severe pathological kidney lesions including glomerular atrophy, degeneration and necrosis of renal tubular epithelial cells in two months tail-suspended rats. Ultrastructural studies of the renal tubular epithelial cells demonstrated that basal laminas of renal tubules were rough and incrassate with mitochondria swelling and vacuolation. Cell apoptosis in kidney monitored by the expression of Bax/Bcl-2 and caspase-3 accompanied these pathological damages caused by long-term microgravity. Analysis of the HSP70 protein expression illustrated that overexpression of HSP70 might play a crucial role in inducing those pathological damages. Glucose regulated protein 78 (GRP78, one of the endoplasmic reticulum (ER chaperones, was up-regulated significantly in the kidney of tail suspension rat, which implied that ER-stress was associated with apoptosis. Furthermore, CHOP and caspase-12 pathways were activated in ER-stress induced apoptosis. Resistance training not only reduced kidney cell apoptosis and expression of HSP70 protein, it also can attenuate the kidney impairment imposed by weightlessness. The appropriate optimization might be needed for the long term application for space exploration.

    2014-01-01

    When there is exposure to ionizing radiation, the probability of developing a stochastic effect increases, and one of the most feared stochastic effects is cancer. Calculations made from data obtained with the population of Hiroshima, showed that these effects have not dose threshold. So it is impossible predict that a specific dose value, will lead to damages and therefore, doses must always be limited. Medical exposures have contributed to the increase in dose received by the populations of countries like Brazil. This is because there was an increase in interventional procedures using ionizing radiation. What has concerned researchers since, many companies did not fit the standards of radiation protection. The proper use of personal protective equipment reduces the exposure of patients and professionals. Trained and knowledgeable of the rules are able to choose the shielding for each type of procedure. So we evaluated the knowledge and radiology professional practice, in protection of patients, who can not be removed from the environment in sinus X-rays and check if the training improves the quality of this service. It was concluded that there is deficiency in knowledge of the rules and failures in protection of patients, and that training with regard to radiological protection increases the level of theoretical knowledge of the professionals involved, and improve their practices with respect to protection, reducing the doses and minimizing the risks involved in medical exposures

    Our book introduces a method to evaluate the accuracy of trend estimation algorithms under conditions similar to those encountered in real time series processing. This method is based on Monte Carlo experiments with artificial time series numerically generated by an original algorithm. The second part of the book contains several automatic algorithms for trend estimation and time series partitioning. The source codes of the computer programs implementing these original automatic algorithms are given in the appendix and will be freely available on the web. The book contains clear statement of the conditions and the approximations under which the algorithms work, as well as the proper interpretation of their results. We illustrate the functioning of the analyzed algorithms by processing time series from astrophysics, finance, biophysics, and paleoclimatology. The numerical experiment method extensively used in our book is already in common use in computational and statistical physics.

Habit strength is conceptualised as a cognitive construct to refer to the psychological...... aspects of the construct, such as routine, inertia, automaticity, or very little conscious deliberation. The data consist of 2962 consumers participating in a large European survey. The results show that habit strength significantly moderates the association between satisfaction and action loyalty, and......, respectively, between intended loyalty and action loyalty. At high levels of habit strength, consumers are more likely to free up cognitive resources and incline the balance from controlled to routine and automatic-like responses....

    The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document &apos

    Gomes, Otávio da F M; Paciornik, Sidnei

    2005-08-01

    A method for automatic classification of the shape of graphite particles in cast iron is proposed. In a typical supervised classification procedure, the standard charts from the ISO-945 standard are used as a training and validation population. Several shape and size parameters are described and used as discriminants. A new parameter, the average internal angle, is proposed and is shown to be relevant for accurate classification. The ideal parameter sets are determined, leading to validation success rates above 90%. The classifier is then applied to real cast iron samples and provides results that are consistent with visual examination. The method provides classification results per particle, different from the traditional per field chart comparison methods. The full procedure can run automatically without user interference.

  3. Automatic target identification using neural networks

    1995-10-01

    Neural network theories are applied to attain human-like performance in areas such as speech recognition, statistical mapping, and target recognition or identification. In target identification, one of the difficult tasks has been the extraction of features to be used to train the neural network which is subsequently used for the target's identification. The purpose of this paper is to describe the development of an automatic target identification system using features extracted from a specific class of targets. The extracted features were the graphical representations of the silhouettes of the targets. Image processing techniques and some Fast Fourier Transform (FFT) properties were implemented to extract the features. The FFT eliminates variations in the extracted features due to rotation or scaling. A Neural Network was trained with the extracted features using the Learning Vector Quantization paradigm. An identification system was set up to test the algorithm. The image processing software was interfaced with MATLAB Neural Network Toolbox via a computer program written in C language to automate the target identification process. The system performed well as at classified the objects used to train it irrespective of rotation, scaling, and translation. This automatic target identification system had a classification success rate of about 95%.

    Becker, Friedhelm; Meier, Gerd E. A.; Wegner, Horst

    1983-03-01

    A system for the automatic evaluation of interference patterns has been developed. After digitizing the interferograms from classical and holografic interferometers with a television digitizer and performing different picture enhancement operations the fringe loci are extracted by use of a floating-threshold method. The fringes are numbered using a special scheme after the removal of any fringe disconnections which might appear if there was insufficient contrast in the interferograms. The reconstruction of the object function from the numbered fringe field is achieved by a local polynomial least-squares approximation. Applications are given, demonstrating the evaluation of interferograms of supersonic flow fields and the analysis of holografic interferograms of car-tyres.

The computing sequence is as follows: normalization of the images; background noise subtraction on both images; evaluation of mercury 197 uptake by the liver and spleen; calculation of the activity fractions on each kidney with respect to the injected dose, taking into account the kidney depth and the results referred to normal values; edition of the results. Automation minimizes the scattering parameters and by its simplification is a great asset in routine work [fr

    A virtual campus, which web address is http://campus virtual.cv.uma.es/, has been created at the University of Malaga. This web site is based on the Moodle Platformer. It consists on a software system designed to help the teacher to create online teaching easily. The main aim of this work is to evaluate the acceptance of this tool by the students, and to compare its utilization with the grades obtained in the Final Exam of June by these students. The whole entrances in the site of the 145 participating students registered trough the course are 7671, which supposes an average of nearly 53 entrances per year per student. The 11.04% of the students have never entered in this site. The students who have obtained the best grades are the ones who have used more this teaching tool. These tools based on new technologies will be a very important support for radiological protection training, which is recommended by International Organizations (EC Report R116 and IAEA Action Plan 2002-2006).

    The results obtained by the Cuban Center for Radiological Protection and Hygiene by using an analytical tree technique to develop its general operational radiation protection program are presented. By the application of this method, some factors such as the organization of the radiation protection services, the provision of administrative requirements, the existing general laboratories requirements, the viability of resources and the current documentation was evaluated. Main components were considered such as: complete normative and regulatory documentation; automatic radiological protection data management; scope of 'on the-job'and radiological protection training for the personnel; previous radiological appraisal for the safety performance of the works and application of dose constrains for the personnel and the public. The detailed development of the program allowed to identify the basic aims to be achieved in its maintenance and improvement. (authors). 3 refs

  9. Automatic Segmentation of Dermoscopic Images by Iterative Classification

    Directory of Open Access Journals (Sweden)

    Maciel Zortea

    2011-01-01

    Full Text Available Accurate detection of the borders of skin lesions is a vital first step for computer aided diagnostic systems. This paper presents a novel automatic approach to segmentation of skin lesions that is particularly suitable for analysis of dermoscopic images. Assumptions about the image acquisition, in particular, the approximate location and color, are used to derive an automatic rule to select small seed regions, likely to correspond to samples of skin and the lesion of interest. The seed regions are used as initial training samples, and the lesion segmentation problem is treated as binary classification problem. An iterative hybrid classification strategy, based on a weighted combination of estimated posteriors of a linear and quadratic classifier, is used to update both the automatically selected training samples and the segmentation, increasing reliability and final accuracy, especially for those challenging images, where the contrast between the background skin and lesion is low.

  10. Automatic readout micrometer

    Science.gov (United States)

    Lauritzen, T.

    A measuring system is described for surveying and very accurately positioning objects with respect to a reference line. A principle use of this surveying system is for accurately aligning the electromagnets which direct a particle beam emitted from a particle accelerator. Prior art surveying systems require highly skilled surveyors. Prior art systems include, for example, optical surveying systems which are susceptible to operator reading errors, and celestial navigation-type surveying systems, with their inherent complexities. The present invention provides an automatic readout micrometer which can very accurately measure distances. The invention has a simplicity of operation which practically eliminates the possibilities of operator optical reading error, owning to the elimination of traditional optical alignments for making measurements. The invention has an extendable arm which carries a laser surveying target. The extendable arm can be continuously positioned over its entire length of travel by either a coarse of fine adjustment without having the fine adjustment outrun the coarse adjustment until a reference laser beam is centered on the target as indicated by a digital readout. The length of the micrometer can then be accurately and automatically read by a computer and compared with a standardized set of alignment measurements. Due to its construction, the micrometer eliminates any errors due to temperature changes when the system is operated within a standard operating temperature range.

  11. Automatic personnel contamination monitor

    1978-01-01

    United Nuclear Industries, Inc. (UNI) has developed an automatic personnel contamination monitor (APCM), which uniquely combines the design features of both portal and hand and shoe monitors. In addition, this prototype system also has a number of new features, including: micro computer control and readout, nineteen large area gas flow detectors, real-time background compensation, self-checking for system failures, and card reader identification and control. UNI's experience in operating the Hanford N Reactor, located in Richland, Washington, has shown the necessity of automatically monitoring plant personnel for contamination after they have passed through the procedurally controlled radiation zones. This final check ensures that each radiation zone worker has been properly checked before leaving company controlled boundaries. Investigation of the commercially available portal and hand and shoe monitors indicated that they did not have the sensitivity or sophistication required for UNI's application, therefore, a development program was initiated, resulting in the subject monitor. Field testing shows good sensitivity to personnel contamination with the majority of alarms showing contaminants on clothing, face and head areas. In general, the APCM has sensitivity comparable to portal survey instrumentation. The inherit stand-in, walk-on feature of the APCM not only makes it easy to use, but makes it difficult to bypass.

    1980-01-01

    General Magnaplate Corporation's pharmaceutical machine is used in the industry for high speed pressing of pills and capsules. Machine is automatic system for molding glycerine suppositories. These machines are typical of many types of drug production and packaging equipment whose metal parts are treated with space spinoff coatings that promote general machine efficiency and contribute to compliance with stringent federal sanitation codes for pharmaceutical manufacture. Collectively known as "synergistic" coatings, these dry lubricants are bonded to a variety of metals to form an extremely hard slippery surface with long lasting self lubrication. The coatings offer multiple advantages; they cannot chip, peel or be rubbed off. They protect machine parts from corrosion and wear longer, lowering maintenance cost and reduce undesired heat caused by power-robbing friction.

    Full Text Available Web applications are becoming an essential part of our everyday lives. Many of our activities are dependent on the functionality and security of these applications. As the scale of these applications grows, injection vulnerabilities such as SQL injection are major security challenges for developers today. This paper presents the technique of automatic query sanitization to automatically remove SQL injection vulnerabilities in code. In our technique, a combination of static analysis and program transformation are used to automatically instrument web applications with sanitization code. We have implemented this technique in a tool named ASSIST (Automatic and Static SQL Injection Sanitization Tool for protecting Java-based web applications. Our experimental evaluation showed that our technique is effective against SQL injection vulnerabilities and has a low overhead.

    2004-01-01

    Automatic sets D part of Z m are characterized by having a finite number of decimations. They are equivalently generated by fixed points of certain substitution systems, or by certain finite automata. As examples, two-dimensional versions of the Thue-Morse, Baum-Sweet, Rudin-Shapiro and paperfolding sequences are presented. We give a necessary and sufficient condition for an automatic set D part of Z m to be a Delone set in R m . The result is then extended to automatic sets that are defined as fixed points of certain substitutions. The morphology of automatic sets is discussed by means of examples

  18. Robust automatic camera pointing for airborne surveillance

    Science.gov (United States)

    Dwyer, David; Wren, Lee; Thornton, John; Bonsor, Nigel

    2002-08-01

    Airborne electro-optic surveillance from a moving platform currently requires regular interaction from a trained operator. Even simple tasks such as fixating on a static point on the ground can demand constant adjustment of the camera orientation to compensate for platform motion. In order to free up operator time for other tasks such as navigation and communication with ground assets, an automatic gaze control system is needed. This paper describes such a system, based purely on tracking points within the video image. A number of scene points are automatically selected and their inter-frame motion tracked. The scene motion is then estimated using a model of a planar projective transform. For reliable and accurate camera pointing, the modeling of the scene motion must be robust to common problems such as scene point obscuration, objects moving independently within the scene and image noise. This paper details a COTS based system for automatic camera fixation and describes ways of preventing objects moving in the scene or poor motion estimates from corrupting the scene motion model.

    The LHC is equipped with a complex collimation system to protect sensitive equipment from unavoidable beam losses. Collimators are positioned close to the beam using an alignment procedure. Until now they have always been aligned assuming no tilt between the collimator and the beam, however, tank misalignments or beam envelope angles at large-divergence locations could introduce a tilt limiting the collimation performance. Three different algorithms were implemented to automatically align a chosen collimator at various angles. The implementation was tested on a number of collimators during this MD and no human intervention was required.

    This alkaloid automated removal machine was developed at Instrumentation Laboratory, Universiti Sultan Zainal Abidin Malaysia that purposely for removing the alkaloid toxicity from Dioscorea hispida (DH) tuber. It is a poisonous plant where scientific study has shown that its tubers contain toxic alkaloid constituents, dioscorine. The tubers can only be consumed after it poisonous is removed. In this experiment, the tubers are needed to blend as powder form before inserting into machine basket. The user is need to push the START button on machine controller for switching the water pump ON by then creating turbulence wave of water in machine tank. The water will stop automatically by triggering the outlet solenoid valve. The powders of tubers are washed for 10 minutes while 1 liter of contaminated water due toxin mixture is flowing out. At this time, the controller will automatically triggered inlet solenoid valve and the new water will flow in machine tank until achieve the desire level that which determined by ultra sonic sensor. This process will repeated for 7 h and the positive result is achieved and shows it significant according to the several parameters of biological character ofpH, temperature, dissolve oxygen, turbidity, conductivity and fish survival rate or time. From that parameter, it also shows the positive result which is near or same with control water and assuming was made that the toxin is fully removed when the pH of DH powder is near with control water. For control water, the pH is about 5.3 while water from this experiment process is 6.0 and before run the machine the pH of contaminated water is about 3.8 which are too acid. This automated machine can save time for removing toxicity from DH compared with a traditional method while less observation of the user.

    A Machine Protection System implemented on the SLC automatically controls the beam repetition rates in the accelerator so that radiation or temperature faults slow the repetition rate to bring the fault within tolerance without shutting down the machine. This process allows the accelerator to aid in the fault diagnostic process, and the protection system automatically restores the beams back to normal rates when the fault is diagnosed and corrected. The user interface includes facilities to monitor the performance of the system, and track rate limits, faults, and recoveries. There is an edit facility to define the devices to be included in the protection system, along with their set points, limits, and trip points.

    2016-01-01

    Full Text Available Modern optimization algorithms typically require the setting of a large number of parameters to optimize their performance. The immediate goal of automatic algorithm configuration is to find, automatically, the best parameter settings of an optimizer. Ultimately, automatic algorithm configuration has the potential to lead to new design paradigms for optimization software. The irace package is a software package that implements a number of automatic configuration procedures. In particular, it offers iterated racing procedures, which have been used successfully to automatically configure various state-of-the-art algorithms. The iterated racing procedures implemented in irace include the iterated F-race algorithm and several extensions and improvements over it. In this paper, we describe the rationale underlying the iterated racing procedures and introduce a number of recent extensions. Among these, we introduce a restart mechanism to avoid premature convergence, the use of truncated sampling distributions to handle correctly parameter bounds, and an elitist racing procedure for ensuring that the best configurations returned are also those evaluated in the highest number of training instances. We experimentally evaluate the most recent version of irace and demonstrate with a number of example applications the use and potential of irace, in particular, and automatic algorithm configuration, in general.

    Automatic license plate recognition (ALPR) is an important capability for traffic surveillance applications, including toll monitoring and detection of different types of traffic violations. ALPR is a multi-stage process comprising plate localization, character segmentation, optical character recognition (OCR), and identification of originating jurisdiction (i.e. state or province). Training of an ALPR system for a new jurisdiction typically involves gathering vast amounts of license plate images and associated ground truth data, followed by iterative tuning and optimization of the ALPR algorithms. The substantial time and effort required to train and optimize the ALPR system can result in excessive operational cost and overhead. In this paper we propose a framework to create an artificial set of license plate images for accelerated training and optimization of ALPR algorithms. The framework comprises two steps: the synthesis of license plate images according to the design and layout for a jurisdiction of interest; and the modeling of imaging transformations and distortions typically encountered in the image capture process. Distortion parameters are estimated by measurements of real plate images. The simulation methodology is successfully demonstrated for training of OCR.

  14. Automatic exposure for xeromammography

    International Nuclear Information System (INIS)

    Aichinger, H.

    1977-01-01

    During mammography without intensifying screens, exposure measurements are carried out behind the film. It is, however, difficult to construct an absolutely shadow-free ionization chamber of adequate sensitivity working in the necessary range of 25 to 50 kV. Repeated attempts have been made to utilize the advantages of automatic exposure for xero-mammography. In this case also the ionization chamber was placed behind the Xerox plate. Depending on tube filtration, object thickness and tube voltage, more than 80%, sometimes even 90%, of the radiation is absorbed by the Xerox plate. Particularly the characteristic Mo radiation of 17.4 keV and 19.6 keV is almost totally absorbed by the plate and cannot therefore be registered by the ionization chamber. This results in a considerable dependence of the exposure on kV and object thickness. Dependence on tube voltage and object thickness have been examined dosimetrically and spectroscopically with a Ge(Li)-spectrometer. Finally, the successful use of a shadow-free chamber is described; this has been particularly adapted for xero-mammography and is placed in front of the plate. (orig) [de

    The importance of operator training using operator training simulator has been recognized intensively. Since 1986, we have been developing and providing many PWR simulators in Japan. We also have developed some training support systems connected with the simulator and the integrated training support system to improve training effect and to reduce instructor's workload. This paper describes the concept and the effect of the integrated training support system and of the following sub-systems. We have PES (Performance Enhancement System) that evaluates training performance automatically by analyzing many plant parameters and operation data. It can reduce the deviation of training performance evaluation between instructors. PEL (Parameter and Event data Logging system), that is the subset of PES, has some data-logging functions. And we also have TPES (Team Performance Enhancement System) that is used aiming to improve trainees' ability for communication between operators. Trainee can have conversation with virtual trainees that TPES plays automatically. After that, TPES automatically display some advice to be improved. RVD (Reactor coolant system Visual Display) displays the distributed hydraulic-thermal condition of the reactor coolant system in real-time graphically. It can make trainees understand the inside plant condition in more detail. These sub-systems have been used in a training center and have contributed the improvement of operator training and have gained in popularity. (author)

    This Practical Radiation Technical Manual is one of a series that has been designed to provide guidance on radiological protection for employers, radiation protection officers, managers and other technically competent persons who have responsibility for ensuring the safety of employees working with ionizing radiation. The Manual may be used with the appropriate IAEA Practical Radiation Safety Manuals to provide training, instruction and information for all employees engaged in work with ionizing radiation. Personal protective equipment (PPE) includes clothing or other special equipment that is issued to individual workers to provide protection against actual or potential exposure to ionizing radiations. It is used to protect each worker against the prevailing risk of external or internal exposure in circumstances in which it is not reasonably practicable to provide complete protection by means of engineering controls or administrative methods. Adequate personal protection depends on PPE being correctly selected, fitted and maintained. Appropriate training for the users and arrangements to monitor usage are also necessary to ensure that PPE provides the intended degree of protection effectively. This Manual explains the principal types of PPE, including protective clothing and respiratory protective equipment (RPE). Examples of working procedures are also described to indicate how PPE should be used within a safe system of work. The Manual will be of most benefit if it forms part of a more comprehensive training programme or is supplemented by the advice of a qualified expert in radiation protection. Some of the RPE described in this Manual should be used under the guidance of a qualified expert

  18. Control of automatic processes: A parallel distributed-processing model of the stroop effect. Technical report

    Cohen, J.D.; Dunbar, K.; McClelland, J.L.

    1988-06-16

    A growing body of evidence suggests that traditional views of automaticity are in need of revision. For example, automaticity has often been treated as an all-or-none phenomenon, and traditional theories have held that automatic processes are independent of attention. Yet recent empirial data suggests that automatic processes are continuous, and furthermore are subject to attentional control. In this paper we present a model of attention which addresses these issues. Using a parallel distributed processing framework we propose that the attributes of automaticity depend upon the strength of a process and that strength increases with training. Using the Stroop effect as an example, we show how automatic processes are continuous and emerge gradually with practice. Specifically, we present a computational model of the Stroop task which simulates the time course of processing as well as the effects of learning.

  4. Clothes Dryer Automatic Termination Evaluation

    Energy Technology Data Exchange (ETDEWEB)

    TeGrotenhuis, Ward E.

    2014-10-01

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    Full Text Available Our paper focuses on the graphical analysis domain. We propose an automatic image recognition technique. This approach consists of two main pattern recognition steps. First, it performs an image feature extraction operation on an input image set, using statistical dispersion features. Then, an unsupervised classification process is performed on the previously obtained graphical feature vectors. An automatic region-growing based clustering procedure is proposed and utilized in the classification stage.

    Diseased skeletal muscle expresses mononuclear cell infiltration in the regions of perimysium. Accurate annotation or segmentation of perimysium can help biologists and clinicians to determine individualized patient treatment and allow for reasonable prognostication. However, manual perimysium annotation is time consuming and prone to inter-observer variations. Meanwhile, the presence of ambiguous patterns in muscle images significantly challenge many traditional automatic annotation algorithms. In this paper, we propose an automatic perimysium annotation algorithm based on deep convolutional neural network (CNN). We formulate the automatic annotation of perimysium in muscle images as a pixel-wise classification problem, and the CNN is trained to label each image pixel with raw RGB values of the patch centered at the pixel. The algorithm is applied to 82 diseased skeletal muscle images. We have achieved an average precision of 94% on the test dataset.

  8. Post-training N-methyl-D-aspartate receptor blockade offers protection from retrograde interference but does not affect consolidation of weak or strong memory traces in the water maze.

    Day, M; Langston, R F

    2006-01-01

    Memory consolidation is the process where labile memory traces become long-lasting, stable memories. Previous work has demonstrated that spatial memory consolidation, several days after training in a water maze had ceased, can be disrupted by a temporary intra hippocampal infusion of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid/kainate antagonist LY326325 (Riedel et al., 1999). Such reversible pharmacological techniques offer advantages over the permanent lesion studies that had first suggested a role for the hippocampus in memory consolidation. However, to date the role of N-methyl-D-aspartate receptors in such systems level processes remains controversial with evidence for impairments and augmentation of performance. Here we investigate the role of post-training hippocampal N-methyl-D-aspartate receptor blockade in rats and mice on the consolidation of weak and strong memory traces using an Atlantis water maze protocol. A hidden Atlantis platform was employed and rats (experiments 1 and 2) and mice (experiment 3) were required to dwell within 20 cm of the trained location to activate and subsequently reveal the escape platform. In experiments 1 and 3 a strong memory trace was established by training rats or mice for several days in the water maze. In experiment 2 a significantly weaker trace was instituted by reducing the training period. N-methyl-D-aspartate receptor blockade was induced after the last training trial and continued for seven days. Reliable memory for the trained platform location in a retention test 15 days after the last training day demonstrated that N-methyl-D-aspartate receptor blockade did not affect memory consolidation in rats or mice. Our results also show that post-training N-methyl-D-aspartate receptor blockade can lead to better performance in further retention tests conducted after the consolidation and drug administration period. Those data suggest that specific post-training N-methyl-D-aspartate receptor blockade

    Diabetic retinopathy (DR) is a disease in which the retina is damaged due to augmentation in the blood pressure of small vessels. DR is the major cause of blindness for diabetics. It has been shown that early diagnosis can play a major role in prevention of visual loss and blindness. This work proposes a computer based approach for the detection of DR in back-of-the-eye images based on the use of convolutional neural networks (CNNs). Our CNN uses deep architectures to classify Back-of-the-eye Retinal Photographs (BRP) in 5 stages of DR. Our method combines several preprocessing images of BRP to obtain an ACA score of 50.5%. Furthermore, we explore subproblems by training a larger CNN of our main classification task.

    To develop a research ethics training course for American Indian/Alaskan Native health clinic staff and community researchers who would be conducting human subjects research. Community-based participatory research methods were used in facilitated discussions of research ethics centered around topics included in the Collaborative Institutional Training Initiative research ethics course. The community-based participatory research approach allowed all partners to jointly develop a research ethics training program that was relevant for American Indian/Alaskan Native communities. All community and clinic partners were able to pass the Collaborative Institutional Training Initiative course they were required to pass so that they could be certified to conduct research with human subjects on federally funded projects. In addition, the training sessions provided a foundation for increased community oversight of research. By using a collaborative process to engage community partners in research ethics discussions, rather than either an asynchronous online or a lecture/presentation format, resulted in significant mutual learning about research ethics and community concerns about research. This approach requires university researchers to invest time in learning about the communities in which they will be working prior to the training. © 2014 Society for Public Health Education.

  12. Automatic Door Access System Using Face Recognition

    2015-06-01

    Full Text Available Abstract Most doors are controlled by persons with the use of keys security cards password or pattern to open the door. Theaim of this paper is to help users forimprovement of the door security of sensitive locations by using face detection and recognition. Face is a complex multidimensional structure and needs good computing techniques for detection and recognition. This paper is comprised mainly of three subsystems namely face detection face recognition and automatic door access control. Face detection is the process of detecting the region of face in an image. The face is detected by using the viola jones method and face recognition is implemented by using the Principal Component Analysis PCA. Face Recognition based on PCA is generally referred to as the use of Eigenfaces.If a face is recognized it is known else it is unknown. The door will open automatically for the known person due to the command of the microcontroller. On the other hand alarm will ring for the unknown person. Since PCA reduces the dimensions of face images without losing important features facial images for many persons can be stored in the database. Although many training images are used computational efficiency cannot be decreased significantly. Therefore face recognition using PCA can be more useful for door security system than other face recognition schemes.

    In recent years the concept of quality assurance in radiology has become as popular as the apple pie. Unfortunately, however, the concept means different things to different people. Furthermore, the methods proposed are very many and diversified. The present article will focus on the quality assurance in the use of the automatic processor equipment. With automatic film processors, there are many factors which can cause a reduction in image quality, but they center on the following: (1) chemical solutions, (2) mechanical parts of the equipment, and (3) faults in processing and its management, which are discussed in some detail. Quality assurance helps to ensure satisfactory performance of the automatic processor equipment for high image quality. The following record keeping is required: - For equipment quality control: 1) daily maintenance record, 2) weekly maintenance record. 3) monthly main tenancy record, and 4) ph value record based on tests with litmus paper. - Training of the personal is required in the following subjects: 1) safety in processing operation, 2) management of the automatic processor equipment (a manual will be used), 3) acquisition and absorption of latest information on the automatic processor equipment system. - The procedures described above are considered necessary for efficient processing operations which will give high and uniform image quality

    Due to the dramatic growth of network and multimedia technology, people can more easily get variant information by using Internet. Unfortunately, it also makes the diffusion of illegal and harmful content much easier. So, it becomes an important topic for the Internet society to protect and safeguard Internet users from these content that may be encountered while surfing on the Net, especially children. Among these content, porno graphs cause more serious harm. Therefore, in this study, we propose an automatic system to detect still colour porno graphs. Starting from this result, we plan to develop an automatic system to search porno graphs or to filter porno graphs. Almost all the porno graphs possess one common characteristic that is the ratio of the size of skin region and non-skin region is high. Based on this characteristic, our system first converts the colour space from RGB colour space to HSV colour space so as to segment all the possible skin-colour regions from scene background. We also apply the texture analysis on the selected skin-colour regions to separate the skin regions from non-skin regions. Then, we try to group the adjacent pixels located in skin regions. If the ratio is over a given threshold, we can tell if the given image is a possible porno graph. Based on our experiment, less than 10% of non-porno graphs are classified as pornography, and over 80% of the most harmful porno graphs are classified correctly.

    1977-01-01

    This paper discuss design and operation of an automatic system for control of skip hoisting in the Barbara-Chorzow black coal mine in Poland. The control system for skip hoists consists of the CKD manual control system and an automatic control system developed in Poland. Number of common elements of the 2 control systems was reduced to a minimum. Main functional elements of the automatic control system are described: a control-point setting element, a hoisting-speed control element, and element for control of hoisting current and for limiting current during stoppage, a relay control and protection element. Design of the elements is shown in 11 schemes and diagrams. The system is characterized by low price and installation cost (550,000 zlotys) in comparison to cost of the ASEA control system (1,800,000 zlotys) or that of the PMUE system (1,200,000 zlotys), high reliability and control efficiency. In spite of increased ambient temperature, temperature of the drive system with the automatic control system was within permissible limits. Performance tests showed that an independent system for manual and automatic control of hoist drive is superior to an integrated control system. 2 refs.

    1978-10-01

    This manual describes and provides trouble-shooting aids for the Automatic Sample Changer electronics on the automatic beta counting system, developed by the Los Alamos Scientific Laboratory Group CNC-11. The output of a gas detector is shaped by a preamplifier, then is coupled to an amplifier. Amplifier output is discriminated and is the input to a scaler. An identification number is associated with each sample. At a predetermined count length, the identification number, scaler data plus other information is punched out on a data card. The next sample to be counted is automatically selected. The beta counter uses the same electronics as the prior count did, the only difference being the sample identification number and sample itself. This manual is intended as a step-by-step aid in trouble-shooting the electronics associated with positioning the sample, counting the sample, and getting the needed data punched on an 80-column data card

  1. Automatic Earthquake Detection by Active Learning

    Science.gov (United States)

    Bergen, K.; Beroza, G. C.

    2017-12-01

    In recent years, advances in machine learning have transformed fields such as image recognition, natural language processing and recommender systems. Many of these performance gains have relied on the availability of large, labeled data sets to train high-accuracy models; labeled data sets are those for which each sample includes a target class label, such as waveforms tagged as either earthquakes or noise. Earthquake seismologists are increasingly leveraging machine learning and data mining techniques to detect and analyze weak earthquake signals in large seismic data sets. One of the challenges in applying machine learning to seismic data sets is the limited labeled data problem; learning algorithms need to be given examples of earthquake waveforms, but the number of known events, taken from earthquake catalogs, may be insufficient to build an accurate detector. Furthermore, earthquake catalogs are known to be incomplete, resulting in training data that may be biased towards larger events and contain inaccurate labels. This challenge is compounded by the class imbalance problem; the events of interest, earthquakes, are infrequent relative to noise in continuous data sets, and many learning algorithms perform poorly on rare classes. In this work, we investigate the use of active learning for automatic earthquake detection. Active learning is a type of semi-supervised machine learning that uses a human-in-the-loop approach to strategically supplement a small initial training set. The learning algorithm incorporates domain expertise through interaction between a human expert and the algorithm, with the algorithm actively posing queries to the user to improve detection performance. We demonstrate the potential of active machine learning to improve earthquake detection performance with limited available training data.

    Protected sleep periods for internal medicine interns have previously resulted in increased amount slept and improved cognitive alertness but required supplemental personnel. The authors evaluated intern and patient outcomes associated with protected nocturnal nap periods of three hours that are personnel neutral. Randomized trial at Philadelphia Veterans Affairs Medical Center (PVAMC) Medical Service and Hospital of the University of Pennsylvania (HUP) Oncology Unit. During 2010-2011, four-week blocks were randomly assigned to a standard intern schedule (extended duty overnight shifts of up to 30 hours), or sequential protected sleep periods (phone sign-out midnight to 3:00 AM [early shift] intern 1; 3:00 to 6:00 AM [late shift] intern 2). Participants wore wrist Actiwatches, completed sleep diaries, and performed daily assessments of behavioral alertness. Between-group comparisons of means and proportions controlled for within-person correlations. HUP interns had significantly longer sleep durations during both early (2.40 hours) and late (2.44 hours) protected periods compared with controls (1.55 hours, P sleep duration was longer only for the late shift group (2.40 versus 1.90 hours, P period were significantly less likely to have call nights with no sleep and had fewer attentional lapses on the Psychomotor Vigilance Test. Differences in patient outcomes between standard schedule months versus intervention months were not observed. Protected sleep periods of three hours resulted in more sleep during call and reductions in periods of prolonged wakefulness, providing a plausible alternative to 16-hour shifts.

    Parkinson's disease (PD) is a neurodegenerative disorder, caused by the gradual loss of cells in substantia nigra. Nitric oxide (NO) plays an important role in a variety of signal transduction pathways that are crucial for maintaining the physiologic functions of nervous system. The aims of this study are: 1) To investigate the expression of the inducible form of NO (iNOS), and compare it to neuronal nitric oxide (nNOS) in the brain of a chronic mouse model of PD and 2) To study the effect of endurance exercise training on the expression of these markers. Mouse models of PD were obtained using 10 doses of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (25 mg/kg) and probenecid (250 mg/kg) over 5 weeks. Forty C57BL /6 albino mice were randomly divided into four groups: sedentary control (SC, N = 10), exercise control (EC, N = 10), sedentary PD (SPD, N = 10), exercise PD (EPD, N = 10). At the end of training program, nNOS and iNOS were evaluated in the striatum in all animal groups using immunohistochemistry. nNOS showed significant increases in striatum (ST) of SPD mice compared to SC mice (P > 0.03). There was also decreased expression of nNOS in EC group compared to SC mice, but this decrease was not significant (P > 0.8). Exercise training significantly decreased the level of nNOS in the EPD compared to SPD, (P > 0.04). Although, iNOS expression followed almost the same trend as nNOS, but exercise training did not significantly decrease the expression of iNOS in both EC and EPD groups, P > 0.2 and 0.3 respectively. The data from this study suggests that 4 weeks of treadmill exercise has a positive impact on the expression of nNOS and iNOS in the striatum of a PD model. This might clear in part the pathogenicity of the diseases and the positive impact of training on PD.

  19. Automatisms: bridging clinical neurology with criminal law.

    2011-03-01

    The law, like neurology, grapples with the relationship between disease states and behavior. Sometimes, the two disciplines share the same terminology, such as automatism. In law, the "automatism defense" is a claim that action was involuntary or performed while unconscious. Someone charged with a serious crime can acknowledge committing the act and yet may go free if, relying on the expert testimony of clinicians, the court determines that the act of crime was committed in a state of automatism. In this review, we explore the relationship between the use of automatism in the legal and clinical literature. We close by addressing several issues raised by the automatism defense: semantic ambiguity surrounding the term automatism, the presence or absence of consciousness during automatisms, and the methodological obstacles that have hindered the study of cognition during automatisms.

    Early identification is crucial for young children with autism to access early intervention. The existing screens require either a parent-report questionnaire and/or direct observation by a trained practitioner. Although an automatic tool would benefit parents, clinicians and children, there is no automatic screening tool in clinical use. This study reports a fully automatic mechanism for autism detection/screening for young children. This is a direct extension of the LENA (Language ENvironment Analysis) system, which utilizes speech signal processing technology to analyze and monitor a child's natural language environment and the vocalizations/speech of the child. It is discovered that child vocalization composition contains rich discriminant information for autism detection. By applying pattern recognition and machine learning approaches to child vocalization composition data, accuracy rates of 85% to 90% in cross-validation tests for autism detection have been achieved at the equal-error-rate (EER) point on a data set with 34 children with autism, 30 language delayed children and 76 typically developing children. Due to its easy and automatic procedure, it is believed that this new tool can serve a significant role in childhood autism screening, especially in regards to population-based or universal screening.

    2001-01-01

    ROOT version 3 (spring 2001) supports automatic class schema evolution. In addition this version also produces files that are self-describing. This is achieved by storing in each file a record with the description of all the persistent classes in the file. Being self-describing guarantees that a file can always be read later, its structure browsed and objects inspected, also when the library with the compiled code of these classes is missing. The schema evolution mechanism supports the frequent case when multiple data sets generated with many different class versions must be analyzed in the same session. ROOT supports the automatic generation of C++ code describing the data objects in a file

    In this paper, we propose a system for automatic design of magazine covers that quantifies a number of concepts from art and aesthetics. Our solution to automatic design of this type of media has been shaped by input from professional designers, magazine art directors and editorial boards, and journalists. Consequently, a number of principles in design and rules in designing magazine covers are delineated. Several techniques are derived and employed in order to quantify and implement these principles and rules in the format of a software framework. At this stage, our framework divides the task of design into three main modules: layout of magazine cover elements, choice of color for masthead and cover lines, and typography of cover lines. Feedback from professional designers on our designs suggests that our results are congruent with their intuition.

    Radioimmunoassay provided dose response curves which showed linearity by the use of logistic transformation (Rodbard). This transformation which was applicable to radioimmunoassay should be useful for the computer processing of insulin and C-peptide assay. In the present studies, standard curves were analysed by testing the fit of analytic functions to radioimmunoassay of insulin and C-peptides. A program for use in combination with the double antibody technique was made by Dr. Kawamata. This approach was evidenced to be useful in order to allow automatic computation of data derived from the double antibody assays of insulin and C-peptides. Automatic corrected calculations of radioimmunoassay data of insulin was found to be satisfactory. (auth.)

    Yu, Zhenwei; Tsai, Jeffrey J P; Weigert, Thomas

    2007-04-01

    An intrusion detection system (IDS) is a security layer used to detect ongoing intrusive activities in information systems. Traditionally, intrusion detection relies on extensive knowledge of security experts, in particular, on their familiarity with the computer system to be protected. To reduce this dependence, various data-mining and machine learning techniques have been deployed for intrusion detection. An IDS is usually working in a dynamically changing environment, which forces continuous tuning of the intrusion detection model, in order to maintain sufficient performance. The manual tuning process required by current systems depends on the system operators in working out the tuning solution and in integrating it into the detection model. In this paper, an automatically tuning IDS (ATIDS) is presented. The proposed system will automatically tune the detection model on-the-fly according to the feedback provided by the system operator when false predictions are encountered. The system is evaluated using the KDDCup'99 intrusion detection dataset. Experimental results show that the system achieves up to 35% improvement in terms of misclassification cost when compared with a system lacking the tuning feature. If only 10% false predictions are used to tune the model, the system still achieves about 30% improvement. Moreover, when tuning is not delayed too long, the system can achieve about 20% improvement, with only 1.3% of the false predictions used to tune the model. The results of the experiments show that a practical system can be built based on ATIDS: system operators can focus on verification of predictions with low confidence, as only those predictions determined to be false will be used to tune the detection model.

    The U.S. government has been assisting the Russian Federation (RF) Ministry of Defense (MOD) for many years with nuclear weapons transportation security (NWTS) through the provision of specialized guard escort railcars and cargo railcars with integrated physical security and communication systems, armored transport vehicles, and armored escort vehicles. As a natural continuation of the NWTS program, a partnership has been formed to construct a training center that will provide counterterrorism training to personnel in all branches of the RF MOD. The Abramovo Counterterrorism Training Center (ACTC) is a multinational, multiagency project with funding from Canada, RF and the U.S. Departments of Defense and Energy. ACTC will be a facility where MOD personnel can conduct basic through advanced training in various security measures to protect Category IA material against the threat of terrorist attack. The training will enhance defense-in-depth principles by integrating MOD guard force personnel into the overall physical protection systems and improving their overall response time and neutralization capabilities. The ACTC project includes infrastructure improvements, renovation of existing buildings, construction of new buildings, construction of new training facilities, and provision of training and other equipment. Classroom training will be conducted in a renovated training building. Basic and intermediate training will be conducted on three different security training areas where various obstacles and static training devices will be constructed. The central element of ACTC, where advanced training will be held, is the 'autodrome,' a 3 km road along which various terrorist events can be staged to challenge MOD personnel in realistic and dynamic nuclear weapons transportation scenarios. This paper will address the ACTC project elements and the vision for training development and integrating this training into actual nuclear weapons transportation operations.

    2012-04-01

    Full Text Available For the Taiwan Power Company (Taipower, the margins of coordination times between the lateral circuit breakers (LCB of underground 4-way automatic line switches and the protection equipment of high voltage customers are often too small. This could lead to sympathy tripping by the feeder circuit breaker (FCB of the distribution feeder and create difficulties in protection coordination between upstream and downstream protection equipment, identification of faults, and restoration operations. In order to solve the problem, it is necessary to reexamine the protection coordination between LCBs and high voltage customers’ protection equipment, and between LCBs and FCBs, in order to bring forth new proposals for settings and operations. This paper applies linear programming to optimize the protection coordination of protection devices, and proposes new time current curves (TCCs for the overcurrent (CO and low-energy overcurrent (LCO relays used in normally open distribution systems by performing simulations in the Electrical Transient Analyzer Program (ETAP environment. The simulation results show that the new TCCs solve the coordination problems among high voltage customer, lateral, feeder, bus-interconnection, and distribution transformer. The new proposals also satisfy the requirements of Taipower on protection coordination of the distribution feeder automation system (DFAS. Finally, the authors believe that the system configuration, operation experience, and relevant criteria mentioned in this paper may serve as valuable references for other companies or utilities when building DFAS of their own.

    Retinopathy of Prematurity (ROP) is an infant disease characterized by increased dilation and tortuosity of the retinal blood vessels. Automatic tortuosity evaluation from retinal digital images is very useful to facilitate an ophthalmologist in the ROP screening and to prevent childhood blindness. This paper proposes a method to automatically classify the image into tortuous and non-tortuous. The process imitates expert ophthalmologists' screening by searching for clearly tortuous vessel segments. First, a skeleton of the retinal blood vessels is extracted from the original infant retinal image using a series of morphological operators. Next, we propose to partition the blood vessels recursively using an adaptive linear interpolation scheme. Finally, the tortuosity is calculated based on the curvature of the resulting vessel segments. The retinal images are then classified into two classes using segments characterized by the highest tortuosity. For an optimal set of training parameters the prediction is as high as 100%.

    2014-01-01

    Full Text Available An approach to automatic hoverfly species discrimination based on detection and extraction of vein junctions in wing venation patterns of insects is presented in the paper. The dataset used in our experiments consists of high resolution microscopic wing images of several hoverfly species collected over a relatively long period of time at different geographic locations. Junctions are detected using the combination of the well known HOG (histograms of oriented gradients and the robust version of recently proposed CLBP (complete local binary pattern. These features are used to train an SVM classifier to detect junctions in wing images. Once the junctions are identified they are used to extract statistics characterizing the constellations of these points. Such simple features can be used to automatically discriminate four selected hoverfly species with polynomial kernel SVM and achieve high classification accuracy.

    1995-02-01

    We have developed a technique for automatically identifying the script used to generate a document that is stored electronically in bit image form. Our approach differs from previous work in that the distinctions among scripts are discovered by an automatic learning procedure, without any handson analysis. We first develop a set of representative symbols (templates) for each script in our database (Cyrillic, Roman, etc.). We do this by identifying all textual symbols in a set of training documents, scaling each symbol to a fixed size, clustering similar symbols, pruning minor clusters, and finding each cluster`s centroid. To identify a new document`s script, we identify and scale a subset of symbols from the document and compare them to the templates for each script. We choose the script whose templates provide the best match. Our current system distinguishes among the Armenian, Burmese, Chinese, Cyrillic, Ethiopic, Greek, Hebrew, Japanese, Korean, Roman, and Thai scripts with over 90% accuracy.

    From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

    Clinicians pose complex clinical questions when seeing patients, and identifying the answers to those questions in a timely manner helps improve the quality of patient care. We report here on two natural language processing models, namely, automatic topic assignment and keyword identification, that together automatically and effectively extract information needs from ad hoc clinical questions. Our study is motivated in the context of developing the larger clinical question answering system AskHERMES (Help clinicians to Extract and aRrticulate Multimedia information for answering clinical quEstionS). We developed supervised machine-learning systems to automatically assign predefined general categories (e.g. etiology, procedure, and diagnosis) to a question. We also explored both supervised and unsupervised systems to automatically identify keywords that capture the main content of the question. We evaluated our systems on 4654 annotated clinical questions that were collected in practice. We achieved an F1 score of 76.0% for the task of general topic classification and 58.0% for keyword extraction. Our systems have been implemented into the larger question answering system AskHERMES. Our error analyses suggested that inconsistent annotation in our training data have hurt both question analysis tasks. Our systems, available at http://www.askhermes.org, can automatically extract information needs from both short (the number of word tokens 20), and from both well-structured and ill-formed questions. We speculate that the performance of general topic classification and keyword extraction can be further improved if consistently annotated data are made available. Copyright © 2010 Elsevier Inc.

    Full Text Available Children who are involved in the child welfare system have experienced trauma, and research indicates that parents of those children also frequently grapple with their own unresolved trauma. In addition, child welfare workers face high rates of secondary traumatic stress. Federal legislation from 2011 requires states to conduct universal trauma screening on children in foster care. The Administration on Children and Families (ACF urges state Child Protection agencies (CPS to become trauma-informed, however, many states still struggle to integrate a trauma focused practice model. This article describes the outcomes of a national, empirically driven, Core Concepts in Child Trauma for Child Welfare curriculum utilized in a Title IV-E university partnership program to teach graduate level child welfare agency supervisors. Findings suggest that the graduate trauma course demonstrates statistically significant gains in confidence, and also has a profound impact on the agency’s transformation into a trauma-informed system

    Full Text Available Abstract Background Curation of information from bioscience literature into biological knowledge databases is a crucial way of capturing experimental information in a computable form. During the biocuration process, a critical first step is to identify from all published literature the papers that contain results for a specific data type the curator is interested in annotating. This step normally requires curators to manually examine many papers to ascertain which few contain information of interest and thus, is usually time consuming. We developed an automatic method for identifying papers containing these curation data types among a large pool of published scientific papers based on the machine learning method Support Vector Machine (SVM. This classification system is completely automatic and can be readily applied to diverse experimental data types. It has been in use in production for automatic categorization of 10 different experimental datatypes in the biocuration process at WormBase for the past two years and it is in the process of being adopted in the biocuration process at FlyBase and the Saccharomyces Genome Database (SGD. We anticipate that this method can be readily adopted by various databases in the biocuration community and thereby greatly reducing time spent on an otherwise laborious and demanding task. We also developed a simple, readily automated procedure to utilize training papers of similar data types from different bodies of literature such as C. elegans and D. melanogaster to identify papers with any of these data types for a single database. This approach has great significance because for some data types, especially those of low occurrence, a single corpus often does not have enough training papers to achieve satisfactory performance. Results We successfully tested the method on ten data types from WormBase, fifteen data types from FlyBase and three data types from Mouse Genomics Informatics (MGI. It is being used in

  9. Effectiveness and Discussion of Ventilation Design with Automatic Revolving Window

    2016-01-01

    Full Text Available This paper aims to improve and discuss the effectiveness of automatic revolving window ventilation on human comfort, where the temperature sensor mounted indoors gives the signal to start the stepping motor of the revolving window. There is a controller for automatic regulation according to the difference between the preset temperature and indoor temperature, where the air flow of ventilating fan imports outside air to take excess heat away from the room, in order to reduce the indoor temperature. The revolving window opening angle is simulated and analyzed, and the impact of different air rates on the indoor temperature is analyzed. This system can regulate the indoor temperature to effectively reach the optimal human comfort temperature, and can reduce the frequency of using air conditioning, in order to attain the goals of energy saving, carbon reduction, and environmental protection.

    Chronic skin diseases like eczema may lead to severe health and financial consequences for patients if not detected and controlled early. Early measurement of disease severity, combined with a recommendation for skin protection and use of appropriate medication can prevent the disease from worsening. Current diagnosis can be costly and time-consuming. In this paper, an automatic eczema detection and severity measurement model are presented using modern image processing and computer algorithm. The system can successfully detect regions of eczema and classify the identified region as mild or severe based on image color and texture feature. Then the model automatically measures skin parameters used in the most common assessment tool called "Eczema Area and Severity Index (EASI)," by computing eczema affected area score, eczema intensity score, and body region score of eczema allowing both patients and physicians to accurately assess the affected skin.

  11. Unification of automatic target tracking and automatic target recognition

    The subject being addressed is how an automatic target tracker (ATT) and an automatic target recognizer (ATR) can be fused together so tightly and so well that their distinctiveness becomes lost in the merger. This has historically not been the case outside of biology and a few academic papers. The biological model of ATT∪ATR arises from dynamic patterns of activity distributed across many neural circuits and structures (including retina). The information that the brain receives from the eyes is "old news" at the time that it receives it. The eyes and brain forecast a tracked object's future position, rather than relying on received retinal position. Anticipation of the next moment - building up a consistent perception - is accomplished under difficult conditions: motion (eyes, head, body, scene background, target) and processing limitations (neural noise, delays, eye jitter, distractions). Not only does the human vision system surmount these problems, but it has innate mechanisms to exploit motion in support of target detection and classification. Biological vision doesn't normally operate on snapshots. Feature extraction, detection and recognition are spatiotemporal. When vision is viewed as a spatiotemporal process, target detection, recognition, tracking, event detection and activity recognition, do not seem as distinct as they are in current ATT and ATR designs. They appear as similar mechanism taking place at varying time scales. A framework is provided for unifying ATT and ATR.

    Most of the institutional and research information in the biomedical domain is available in the form of English text. Even in countries where English is an official language, such as the United States, language can be a barrier for accessing biomedical information for non-native speakers. Recent progress in machine translation suggests that this technique could help make English texts accessible to speakers of other languages. However, the lack of adequate specialized corpora needed to train statistical models currently limits the quality of automatic translations in the biomedical domain. We show how a large-sized parallel corpus can automatically be obtained for the biomedical domain, using the MEDLINE database. The corpus generated in this work comprises article titles obtained from MEDLINE and abstract text automatically retrieved from journal websites, which substantially extends the corpora used in previous work. After assessing the quality of the corpus for two language pairs (English/French and English/Spanish) we use the Moses package to train a statistical machine translation model that outperforms previous models for automatic translation of biomedical text. We have built translation data sets in the biomedical domain that can easily be extended to other languages available in MEDLINE. These sets can successfully be applied to train statistical machine translation models. While further progress should be made by incorporating out-of-domain corpora and domain-specific lexicons, we believe that this work improves the automatic translation of biomedical texts.

    Full Text Available The main objective of this paper was to design a model of automatic keyphrase indexing for Persian. The train model, consisting of six features – “TF”, “TF × IDF”, “RE”, “RE × IDF”, “Node Degree” and “First Occurrence” – were elaborated on. These six features were defined briefly and for each feature, the discretization ranges applied as well as the Yes/No probability scores of being an index term were reported. Finally, the way the model, and each of its components, performed were demonstrated in a step-by-step manner by running the software on a sample full-text article. The ultimate assessment of the software on 75 test articles revealed that it had a very good performance on full-texts (F-measure = 27.3%, Precision = 31.68%, and recall = 25.45% and abstracts (F-measure = 28%, precision = 32.19%, and recall = 26.27% when default was set at 7. The software also proved successful as regards generation of keyphrases rather than single word index terms at default 7. In all, 58.1% of the index terms generated by the software for full-text documents, and 58.67% of those generated for abstracts were phrases. Finally, 78.86% and 74.48% of the keyterms generated for full-texts and abstracts were judged as relevant by an LIS expert.

  15. On automatic machine translation evaluation

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available An important task of developing machine translation (MT is evaluating system performance. Automatic measures are most commonly used for this task, as manual evaluation is time-consuming and costly. However, to perform an objective evaluation is not a trivial task. Automatic measures, such as BLEU, TER, NIST, METEOR etc., have their own weaknesses, while manual evaluations are also problematic since they are always to some extent subjective. In this paper we test the influence of a test set on the results of automatic MT evaluation for the subtitling domain. Translating subtitles is a rather specific task for MT, since subtitles are a sort of summarization of spoken text rather than a direct translation of (written text. Additional problem when translating language pair that does not include English, in our example Slovene-Serbian, is that commonly the translations are done from English to Serbian and from English to Slovenian, and not directly, since most of the TV production is originally filmed in English. All this poses additional challenges to MT and consequently to MT evaluation. Automatic evaluation is based on a reference translation, which is usually taken from an existing parallel corpus and marked as a test set. In our experiments, we compare the evaluation results for the same MT system output using three types of test set. In the first round, the test set are 4000 subtitles from the parallel corpus of subtitles SUMAT. These subtitles are not direct translations from Serbian to Slovene or vice versa, but are based on an English original. In the second round, the test set are 1000 subtitles randomly extracted from the first test set and translated anew, from Serbian to Slovenian, based solely on the Serbian written subtitles. In the third round, the test set are the same 1000 subtitles, however this time the Slovene translations were obtained by manually correcting the Slovene MT outputs so that they are correct translations of the

    We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users\\' fairness. The results, which are obtained for single- and multiple-antenna setups, demonstrate the efficiency of the proposed approach in different conditions. For instance, with a maximum of M retransmissions and single transmit/receive antennas, the diversity gain of a user increases from M to (J+1)(M-1)+1 where J is the number of users helping that user.

  19. Motor automaticity in Parkinson’s disease

    2017-01-01

    Bradykinesia is the most important feature contributing to motor difficulties in Parkinson’s disease (PD). However, the pathophysiology underlying bradykinesia is not fully understood. One important aspect is that PD patients have difficulty in performing learned motor skills automatically, but this problem has been generally overlooked. Here we review motor automaticity associated motor deficits in PD, such as reduced arm swing, decreased stride length, freezing of gait, micrographia and reduced facial expression. Recent neuroimaging studies have revealed some neural mechanisms underlying impaired motor automaticity in PD, including less efficient neural coding of movement, failure to shift automated motor skills to the sensorimotor striatum, instability of the automatic mode within the striatum, and use of attentional control and/or compensatory efforts to execute movements usually performed automatically in healthy people. PD patients lose previously acquired automatic skills due to their impaired sensorimotor striatum, and have difficulty in acquiring new automatic skills or restoring lost motor skills. More investigations on the pathophysiology of motor automaticity, the effect of L-dopa or surgical treatments on automaticity, and the potential role of using measures of automaticity in early diagnosis of PD would be valuable.

    The survival rate of out-of-hospital cardiac arrest in Hong Kong is low. A long delay between collapse and defibrillation is a contributing factor. Public access to defibrillation may shorten this delay. It is unknown, however, whether Hong Kong's public is willing or able to use an automatic external defibrillator. This study aimed to evaluate public knowledge of how to use an automatic external defibrillator in out-of-hospital cardiac arrest. A face-to-face semi-structured questionnaire survey of the public was conducted in six locations with a high pedestrian flow in Hong Kong. In this study, 401 members of the public were interviewed. Most had no training in first aid (65.8%) or in use of an automatic external defibrillator (85.3%). Nearly all (96.5%) would call for help for a victim of out-of-hospital cardiac arrest but only 18.0% would use an automatic external defibrillator. Public knowledge of automatic external defibrillator use was low: 77.6% did not know the location of an automatic external defibrillator in the vicinity of their home or workplace. People who had ever been trained in both first aid and use of an automatic external defibrillator were more likely to respond to and help a victim of cardiac arrest, and to use an automatic external defibrillator. Public knowledge of automatic external defibrillator use is low in Hong Kong. A combination of training in first aid and in the use of an automatic external defibrillator is better than either one alone.

    1989-11-22

    A growing body of evidence suggests that traditional views of automaticity are in need of revision. For example, automaticity has often been treated as an all-or-none phenomenon, and traditional theories have held that automatic processes are independent of attention. Yet recent empirical data suggest that automatic processes are continuous, and furthermore are subject to attentional control. In this paper we present a model of attention which addresses these issues. Using a parallel distributed processing framework we propose that the attributes of automaticity depend upon the strength of a processing pathway and that strength increases with training. Using the Stroop effect as an example, we show how automatic processes are continuous and emerge gradually with practice. Specifically, we present a computational model of the Stroop task which simulates the time course of processing as well as the effects of learning. This was accomplished by combining the cascade mechanism described by McClelland (1979) with the back propagation learning algorithm (Rumelhart, Hinton, Williams, 1986). The model is able to simulate performance in the standard Stroop task, as well as aspects of performance in variants of this task which manipulate SOA, response set, and degree of practice. In the discussion we contrast our model with other models, and indicate how it relates to many of the central issues in the literature on attention, automaticity, and interference.

  3. Towards Autonomous Agriculture: Automatic Ground Detection Using Trinocular Stereovision

    Directory of Open Access Journals (Sweden)

    Annalisa Milella

    2012-09-01

    Full Text Available Autonomous driving is a challenging problem, particularly when the domain is unstructured, as in an outdoor agricultural setting. Thus, advanced perception systems are primarily required to sense and understand the surrounding environment recognizing artificial and natural structures, topology, vegetation and paths. In this paper, a self-learning framework is proposed to automatically train a ground classifier for scene interpretation and autonomous navigation based on multi-baseline stereovision. The use of rich 3D data is emphasized where the sensor output includes range and color information of the surrounding environment. Two distinct classifiers are presented, one based on geometric data that can detect the broad class of ground and one based on color data that can further segment ground into subclasses. The geometry-based classifier features two main stages: an adaptive training stage and a classification stage. During the training stage, the system automatically learns to associate geometric appearance of 3D stereo-generated data with class labels. Then, it makes predictions based on past observations. It serves as well to provide training labels to the color-based classifier. Once trained, the color-based classifier is able to recognize similar terrain classes in stereo imagery. The system is continuously updated online using the latest stereo readings, thus making it feasible for long range and long duration navigation, over changing environments. Experimental results, obtained with a tractor test platform operating in a rural environment, are presented to validate this approach, showing an average classification precision and recall of 91.0% and 77.3%, respectively.

    Mozerov M

    2010-01-01

    Full Text Available A dense matching algorithm that solves the problem of synchronizing prerecorded human motion sequences, which show different speeds and accelerations, is proposed. The approach is based on minimization of MRF energy and solves the problem by using Dynamic Programming. Additionally, an optimal sequence is automatically selected from the input dataset to be a time-scale pattern for all other sequences. The paper utilizes an action specific model which automatically learns the variability of 3D human postures observed in a set of training sequences. The model is trained using the public CMU motion capture dataset for the walking action, and a mean walking performance is automatically learnt. Additionally, statistics about the observed variability of the postures and motion direction are also computed at each time step. The synchronized motion sequences are used to learn a model of human motion for action recognition and full-body tracking purposes.

    Phoropters are the most common instrument used to detect refractive errors. During a refractive exam, lenses are flipped in front of the patient who looks at the eye chart and tries to read the symbols. The procedure is fully dependent on the cooperation of the patient to read the eye chart, provides only a subjective measurement of visual acuity, and can at best provide a rough estimate of the patient's vision. Phoropters are difficult to use for mass screenings requiring a skilled examiner, and it is hard to screen young children and the elderly etc. We have developed a simplified, lightweight automatic phoropter that can measure the optical error of the eye objectively without requiring the patient's input. The automatic holographic adaptive phoropter is based on a Shack-Hartmann wave front sensor and three computercontrolled fluidic lenses. The fluidic lens system is designed to be able to provide power and astigmatic corrections over a large range of corrections without the need for verbal feedback from the patient in less than 20 seconds.

    A remotely controlled automatic special welding machine for piping was developed. This machine is utilized for long distance pipe lines, chemical plants, thermal power generating plants and nuclear power plants effectively from the viewpoint of good quality control, reduction of labor and good controllability. The function of this welding machine is to inspect the shape and dimensions of edge preparation before welding work by the sense of touch, to detect the temperature of melt pool, inspect the bead form by the sense of touch, and check the welding state by ITV during welding work, and to grind the bead surface and inspect the weld metal by ultrasonic test automatically after welding work. The construction of this welding system, the main specification of the apparatus, the welding procedure in detail, the electrical source of this welding machine, the cooling system, the structure and handling of guide ring, the central control system and the operating characteristics are explained. The working procedure and the effect by using this welding machine, and the application to nuclear power plants and the other industrial field are outlined. The HIDIC 08 is used as the controlling computer. This welding machine is useful for welding SUS piping as well as carbon steel piping. (Nakai, Y.)

    Automatic handling device for the steam relief valves (SRV's) is developed in order to achieve a decrease in exposure of workers, increase in availability factor, improvement in reliability, improvement in safety of operation, and labor saving. A survey is made during a periodical inspection to examine the actual SVR handling operation. An SRV automatic handling device consists of four components: conveyor, armed conveyor, lifting machine, and control/monitoring system. The conveyor is so designed that the existing I-rail installed in the containment vessel can be used without any modification. This is employed for conveying an SRV along the rail. The armed conveyor, designed for a box rail, is used for an SRV installed away from the rail. By using the lifting machine, an SRV installed away from the I-rail is brought to a spot just below the rail so that the SRV can be transferred by the conveyor. The control/monitoring system consists of a control computer, operation panel, TV monitor and annunciator. The SRV handling device is operated by remote control from a control room. A trial equipment is constructed and performance/function testing is carried out using actual SRV's. As a result, is it shown that the SRV handling device requires only two operators to serve satisfactorily. The required time for removal and replacement of one SRV is about 10 minutes. (Nogami, K.)

    The use of nuclear emulsions in recent large neutrino experiments is mostly due to the significant results in the developments of this detection technique. In the emulsion films, trajectories of through-going particles are permanently recorded: thus, the emulsion target can be considered not only as a tracking but also as a storing device. If the data readout is performed by automatic scanning systems interfaced to an acquisition computer equipped with a fast frame grabber, nuclear emulsions can be used as very large target detector and quickly analyzed in particle physics experiments. Techniques for automatic scanning of nuclear emulsions have been developed in the early past. The effort was initiated by Niwa at Nagoya (Japan) in the late 70s. The first large-scale application was the CHORUS experiment; then emulsions have been used to search for T neutrinos in a high track density environment like DONUT. In order to measure with high accuracy and high speed, very strict constraints must be satisfied in terms of mechanical precisions, camera speed, image processing power. Recent improvements in this technique are briefly reported

    2014-05-01

    We present a novel framework for the automatic generation of tourist brochures that include routing instructions and additional information presented in the form of so-called detail lenses. The first contribution of this paper is the automatic creation of layouts for the brochures. Our approach is based on the minimization of an energy function that combines multiple goals: positioning of the lenses as close as possible to the corresponding region shown in an overview map, keeping the number of lenses low, and an efficient numbering of the lenses. The second contribution is a route-aware simplification of the graph of streets used for traveling between the points of interest (POIs). This is done by reducing the graph consisting of all shortest paths through the minimization of an energy function. The output is a subset of street segments that enable traveling between all the POIs without considerable detours, while at the same time guaranteeing a clutter-free visualization. © 2014 The Author(s) Computer Graphics Forum © 2014 The Eurographics Association and John Wiley & Sons Ltd.

    When there is exposure to ionizing radiation, the probability of developing a stochastic effect increases, and one of the most feared stochastic effects is cancer. Calculations made from data obtained with the population of Hiroshima, showed that these effects have not dose threshold. So it is impossible predict that a specific dose value, will lead to damages and therefore, doses must always be limited. Medical exposures have contributed to the increase in dose received by the populations of countries like Brazil. This is because there was an increase in interventional procedures using ionizing radiation. What has concerned researchers since, many companies did not fit the standards of radiation protection. The proper use of personal protective equipment reduces the exposure of patients and professionals. Trained and knowledgeable of the rules are able to choose the shielding for each type of procedure. So we evaluated the knowledge and radiology professional practice, in protection of patients, who can not be removed from the environment in sinus X-rays and check if the training improves the quality of this service. It was concluded that there is deficiency in knowledge of the rules and failures in protection of patients, and that training with regard to radiological protection increases the level of theoretical knowledge of the professionals involved, and improve their practices with respect to protection, reducing the doses and minimizing the risks involved in medical exposures.

    De-identification, or identifying and removing protected health information (PHI) from clinical data, is a critical step in making clinical data available for clinical applications and research. This paper presents a natural language processing system for automatic de-identification of psychiatric notes, which was designed to participate in the 2016 CEGS N-GRID shared task Track 1. The system has a hybrid structure that combines machine leaning techniques and rule-based approaches. The rule-based components exploit the structure of the psychiatric notes as well as characteristic surface patterns of PHI mentions. The machine learning components utilize supervised learning with rich features. In addition, the system performance was boosted with integration of additional data to the training set through domain adaptation. The hybrid system showed overall micro-averaged F-score 90.74 on the test set, second-best among all the participants of the CEGS N-GRID task. Copyright © 2017. Published by Elsevier Inc.

    Automatic speed control algorithm is one of the core technologies of train operation control system. It’s a typical multi-objective optimization control algorithm, which achieve the train speed control for timing, comfort, energy-saving and precise parking. At present, the train speed automatic control technology is widely used in metro and inter-city railways. It has been found that the automatic speed control technology can effectively reduce the driver’s intensity, and improve the operation quality. However, the current used algorithm is poor at energy-saving, even not as good as manual driving. In order to solve the problem of energy-saving, this paper proposes an automatic speed control algorithm based on Green CBTC system. Based on the Green CBTC system, the algorithm can adjust the operation status of the train to improve the efficient using rate of regenerative braking feedback energy while ensuring the timing, comfort and precise parking targets. Due to the reason, the energy-using of Green CBTC system is lower than traditional CBTC system. The simulation results show that the algorithm based on Green CBTC system can effectively reduce the energy-using due to the improvement of the using rate of regenerative braking feedback energy.

    The SR-O reactor is an experimental pool-type reactor with a maximum output of 1 MW and maximum thermal neutron flux density of 5.3x10 13 m -2 s -1 . The reactor is described in detail and its specifications are given. The protection and control systems of the reactor permit both manual and automatic operation. The reactor is used for training courses for nuclear power plant operators and for post-graduate study courses for other specialists. Intensive courses for 4 to 6 persons take 15 to 20 days. The course is adjusted to the results of introductory theoretical tests. An optimal teaching method has been developed based on the flowchart algorithmic method, dividing activities into operations (manipulations with controls, issuing commands, making records, etc.) and decision making (information reception and processing).

    This paper presents TeleOphta, an automatic system for screening diabetic retinopathy in teleophthalmology networks. Its goal is to reduce the burden on ophthalmologists by automatically detecting non referable examination records, i.e. examination records presenting no image quality problems and no pathological signs related to diabetic retinopathy or any other retinal pathology. TeleOphta is an attempt to put into practice years of algorithmic developments from our groups. It combines image quality metrics, specific lesion detectors and a generic pathological pattern miner to process the visual content of eye fundus photographs. This visual information is further combined with contextual data in order to compute an abnormality risk for each examination record. The TeleOphta system was trained and tested on a large dataset of 25,702 examination records from the OPHDIAT screening network in Paris. It was able to automatically detect 68% of the non referable examination records while achieving the same sensitivity as a second ophthalmologist. This suggests that it could safely reduce the burden on ophthalmologists by 56%.

    Globally, tuberculosis (TB) remains one of the most deadly diseases. Although several effective diagnosis methods exist, in lower income countries clinics may not be in a position to afford expensive equipment and employ the trained experts needed to interpret results. In these situations, symptoms including cough are commonly used to identify patients for testing. However, self-reported cough has suboptimal sensitivity and specificity, which may be improved by digital detection. This study investigates a simple and easily applied method for TB screening based on the automatic analysis of coughing sounds. A database of cough audio recordings was collected and used to develop statistical classifiers. These classifiers use short-term spectral information to automatically distinguish between the coughs of TB positive and TB negative patients with an accuracy of 78% and an AUC of 0.95. When a set of five clinical measurements is available in addition to the audio, this accuracy improves to 82%. By choosing an appropriate decision threshold, the system can achieve a sensitivity of 95% at a specificity of approximately 72%. The experiments suggest that the classifiers are using some spectral information that is not perceivable by the human auditory system, and that certain frequencies are more useful for classification than others. We conclude that automatic classification of coughing sounds may represent a viable low-cost and low-complexity screening method for TB. © 2018 Institute of Physics and Engineering in Medicine.

  2. Automatic physical inference with information maximizing neural networks

    Compressing large data sets to a manageable number of summaries that are informative about the underlying parameters vastly simplifies both frequentist and Bayesian inference. When only simulations are available, these summaries are typically chosen heuristically, so they may inadvertently miss important information. We introduce a simulation-based machine learning technique that trains artificial neural networks to find nonlinear functionals of data that maximize Fisher information: information maximizing neural networks (IMNNs). In test cases where the posterior can be derived exactly, likelihood-free inference based on automatically derived IMNN summaries produces nearly exact posteriors, showing that these summaries are good approximations to sufficient statistics. In a series of numerical examples of increasing complexity and astrophysical relevance we show that IMNNs are robustly capable of automatically finding optimal, nonlinear summaries of the data even in cases where linear compression fails: inferring the variance of Gaussian signal in the presence of noise, inferring cosmological parameters from mock simulations of the Lyman-α forest in quasar spectra, and inferring frequency-domain parameters from LISA-like detections of gravitational waveforms. In this final case, the IMNN summary outperforms linear data compression by avoiding the introduction of spurious likelihood maxima. We anticipate that the automatic physical inference method described in this paper will be essential to obtain both accurate and precise cosmological parameter estimates from complex and large astronomical data sets, including those from LSST and Euclid.

  3. The role of staff training in the safety of nuclear facilities

    Although nuclear energy largely involves automatic protection systems enabling the effects of human error to be mitigated, the human factor still remains of extreme importance in nuclear risk analysis. Hence, the attainment of the high safety standards sought after for nuclear energy must of necessity entail staff training programmes which take into account the concern for nuclear safety. It is incumbent upon constructors and operators to evolve a training programme suited to each job, and the safety authorities are responsible for assessing whether the programme is satisfactory from the standpoint of safety and, where necessary, for issuing the relevant certificates or permits. The paper makes some comments on the cost of human error and the profitability of investment in training, on the importance of practical training and of the role of simulators, and on the need for operators to note and analyse all operational abnormalities, which are so often an advance warning of accidents. The training of special safety teams is examined, with consideration of three aspects: safety assessment, inspection, and action to be taken in the event of accident. Finally, some information is given on the human reliability studies under way and their implications for nuclear safety and training, with emphasis on the valuable assistance rendered in this matter by international organizations.

    In connenction with the automation of radiation protection in nuclear power plants, an automatic reading device has been developed for the direct input of the readings of pencil dosimeters into a computer. Voltage measurements would be simple but are excluded, because the internal electrode of the dosimeter may not be touched, for operational reasons. This paper describes an optical/electronic conversion device in which the reading of the dosimeter is projected onto a Vidicon, scanned, and converted into a digital signal for output to the computer.

    In this paper, we propose an automatic detection schema including three stages for weld defects in x-ray images. Firstly, the preprocessing procedure for the image is implemented to locate the weld region; Then a classification model which is trained and tested by the patches cropped from x-ray images is constructed based on deep neural network. And this model can learn the intrinsic feature of images without extra calculation; Finally, the sliding-window approach is utilized to detect the whole images based on the trained model. In order to evaluate the performance of the model, we carry out several experiments. The results demonstrate that the classification model we proposed is effective in the detection of welded joints quality.

    Antares is a 24-beam-line CO 2 laser system for controlled fusion research, under construction at Los Alamos Scientific Laboratory (LASL). Rapid automatic alignment of this system is required prior to each experiment shot. The alignment requirements, operational constraints, and a developed prototype system are discussed. A visible-wavelength alignment technique is employed that uses a telescope/TV system to view point light sources appropriately located down the beamline. Auto-alignment is accomplished by means of a video centroid tracker, which determines the off-axis error of the point sources. The error is nulled by computer-driven, movable mirrors in a closed-loop system. The light sources are fiber-optic terminations located at key points in the optics path, primarily at the center of large copper mirrors, and remotely illuminated to reduce heating effects

    In BWR nuclear power stations the Traversing Incore Probe (TIP) system is one of the most important components in reactor monitoring and control. In previous TIP systems, however, operators have suffered from the complexity of operation and long operation time required. The system presented in this paper realizes the automatic operation of the TIP system by monitoring and driving it with a process computer. This system significantly reduces the burden on customer operators and improves plant efficiency by simplifying the operating procedure, augmenting the accuracy of the measured data, and shortening operating time. The process computer is one of the PODIA (Plant Operation by Displayed Information Automation) systems. This computer transfers control signals to the TIP control panel, which in turn drives equipment by microprocessor control. The process computer contains such components as the CRT/KB unit, the printer plotter, the hard copier, and the message typers required for efficient man-machine communications. Its operation and interface properties are described

    An invention is described, relating to a microprocessor based control system for a plurality of movable detectors, e.g. a nuclear reactor flux mapping system, with new system architecture which increases system availability by preventing faults on any of the detection channels from disabling the remaining channels. The system has, say, four drive trains for a number of detectors. Functional separation is realized by having two channels control their associated two drive trains. Redundancy is provided by having dual channels for operator interface. Communications between the functionally separate channels is accomplished by employing two-ported memories in conjunction with multiple microprocessors. (author)

  18. Semi Automatic Ontology Instantiation in the domain of Risk Management

    Science.gov (United States)

    Makki, Jawad; Alquier, Anne-Marie; Prince, Violaine

    One of the challenging tasks in the context of Ontological Engineering is to automatically or semi-automatically support the process of Ontology Learning and Ontology Population from semi-structured documents (texts). In this paper we describe a Semi-Automatic Ontology Instantiation method from natural language text, in the domain of Risk Management. This method is composed from three steps 1 ) Annotation with part-of-speech tags, 2) Semantic Relation Instances Extraction, 3) Ontology instantiation process. It's based on combined NLP techniques using human intervention between steps 2 and 3 for control and validation. Since it heavily relies on linguistic knowledge it is not domain dependent which is a good feature for portability between the different fields of risk management application. The proposed methodology uses the ontology of the PRIMA1 project (supported by the European community) as a Generic Domain Ontology and populates it via an available corpus. A first validation of the approach is done through an experiment with Chemical Fact Sheets from Environmental Protection Agency2.

    Full Text Available - Automatic system has brought many revolutions in the existing technologies. One among the technologies, which has greater developments, is the solar powered automatic shrimp feeding system. For instance, the solar power which is a renewable energy can be an alternative solution to energy crisis and basically reducing man power by using it in an automatic manner. The researchers believe an automatic shrimp feeding system may help solve problems on manual feeding operations. The project study aimed to design and develop a solar powered automatic shrimp feeding system. It specifically sought to prepare the design specifications of the project, to determine the methods of fabrication and assembly, and to test the response time of the automatic shrimp feeding system. The researchers designed and developed an automatic system which utilizes a 10 hour timer to be set in intervals preferred by the user and will undergo a continuous process. The magnetic contactor acts as a switch connected to the 10 hour timer which controls the activation or termination of electrical loads and powered by means of a solar panel outputting electrical power, and a rechargeable battery in electrical communication with the solar panel for storing the power. By undergoing through series of testing, the components of the modified system were proven functional and were operating within the desired output. It was recommended that the timer to be used should be tested to avoid malfunction and achieve the fully automatic system and that the system may be improved to handle changes in scope of the project.
