    Full Text Available The Seine river watershed is characterized by a high population density and intense agricultural activities. Data show low microbiological water quality in the main rivers (Seine, Marne, Oise of the watershed. Today, there is an increasing pressure from different social groups to restore microbiological water quality in order to both increase the safety of drinking water production and to restore the possible use of these rivers for bathing and rowing activities, as they were in the past. A model, appended to the hydro-ecological SENEQUE/Riverstrahler model describing the functioning of large river systems, was developed to describe the dynamics of faecal coliforms (FC, the most usual faecal contamination indicator. The model is able to calculate the distribution of FC concentrations in the whole drainage network resulting from land use and wastewater management in the watershed. The model was validated by comparing calculated FC concentrations with available field data for some well-documented situations in different river stretches of the Seine drainage network. Once validated, the model was used to test various predictive scenarios, as, for example, the impact of the modifications in wastewater treatment planned at the 2012 horizon in the Seine watershed in the scope of the implementation of the european water framework directive. The model was also used to investigate past situations. In particular, the variations of the microbiological water quality in the Parisian area due to population increase and modifications in wastewater management were estimated over the last century. It was shown that the present standards for bathing and other aquatic recreational activities are not met in the large tributaries upstream from Paris since the middle of the 1950's, and at least since the middle of the XIXth century in the main branch of the Seine river downstream from Paris. Efforts carried out for improving urban wastewater treatment in terms

    The wide area networks for data transmission are submitting to evolution process by technological progress and unrelated process to the network. The evolution process can be originated by the bottom up integration of different networks that were born to solve specific problems (i.e.: scientific calculations and business administration). The ENET WAN of ENEA had been submitted to the same evolution progress. In this thesis the author analyze all the problems about WAN with emphasis in ENET WAN. The purpose of this research is the analysis of the present situation in particularly links, efficiency, expenses and throughput. The goal is to suggest alternative solutions to optimized the network and to amplify the throughput by new technology. The research suggests in particularly two new wide area networks: ENET{sub C}-LAN95 e ENET{sub S}ERV96. The first one is a mix interconnection solution, that is basis on the public network C-LAN, with the transportation protocol Frame Relay, and on the private links Numerical Direct Channels (CDN). The second one is also a mix interconnection solution, but it is based on two new network services that are supplied by two new public networks just introduce in Italian telecommunications market since `96. Frame Relay and ATM are the transportation protocol employed.

    In a large enterprise it is difficult for cyber security analysts to know what services and roles every machine on the network is performing (e.g., file server, domain name server, email server). Using network flow data, already collected by most enterprises, we developed a proof-of-concept tool that discovers the roles of a system using both clustering and categorization techniques. The tool's role information would allow cyber analysts to detect consequential changes in the network, initiate incident response plans, and optimize their security posture. The results of this proof-of-concept tool proved to be quite accurate on three real data sets. We will present the algorithms used in the tool, describe the results of preliminary testing, provide visualizations of the results, and discuss areas for future work. Without this kind of situational awareness, cyber analysts cannot quickly diagnose an attack or prioritize remedial actions.

    The present situation of investigation and the future problems of floating nuclear power plants in Japan are examined, referring to those in USA. The committee report on a new power generation system in 1970 is quoted. In this report, the site conditions are supposed to be 5 km offshore, 100m water depth, 60 m/sec wind velocity, 10 m wave height, 200 m wave length, 12 seconds wave period 0.2 g earthquake acceleration, and 2.5 knots tide current. The semisubmersible hull of double construction 15 m under water is employed. A pair of 1,000,000 kW BWR reactors are utilized. A sea water desalting unit using bleed steam from turbines is installed. The solid radioactive wastes packed in drums are disposed in the sea. The design and cost estimation were made. The names of the organizations who have made investigation in this field, namely the Civil Engineering Society, the Sience and Technology Agency and other several centers, are reported. The Chubu Electric Power Company is forwarding its project. Referring to the investigations in USA, the project of Atlantic nuclear power station unit is described. A report of plant design has been submitted by O.P.S. to United States Atomic Energy Commission in 1973. The Coastal Area Facilities Act was instituted in New Jersey in 1973. Although the Atlantic nuclear power station has been postponed, it is the most feasible project. For the realization of a floating nuclear power plant in Japan, investigation must be started on the ground construction that can endure the construction of breakwater in water depth of 14 to 30 meter.

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

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

    Scope of medical exposures is studied, these include: exposure to patients as part of their diagnosis or treatment, exposures to persons who knowingly have assisted patients, exposures volunteers included in biomedical research programs. Medical exposures have contributed their benefits for human health improvement: possess a necessary character that people have to be exposed to radiation doses to achieve their goals, convergence of risk and benefit in the same individual is presented, variability is implicated in dose given to patients in terms of size and distribution, have contributed significantly to the doses received by the world population. Despite the above attributes and generally contribute to the direct benefit of the patient, long has been given less attention than other forms of exposure, there still potential for dose reduction to patients as a result of the applications of ionizing radiation. Currently have used for nuclear medicine diagnostic x-ray procedures, exams MN, radiotherapy, tomography, both medical and dental radiology. (author) [es

    Occupational exposure to carcinogens can result in the development of malignancies after a latent period as long as 45 years. New cases are therefore still being detected, although known carcinogens have been banned for some 30 years. Presenting symptoms, investigative techniques, types of bladder carcinoma and methods of spread are all discussed. Criteria for treatment selection are based on the stage of development of the tumor. Radiotherapy requires preliminary localization of the bladder in relation to external marks. A mercury-filled balloon is carefully positioned in the bladder at the internal meatus, and fluoroscopy provides films which are used in final calculations of dose distribution. A dose of 6000 rad is given by a 300 deg rotational technique over 6 weeks to the tumor volume contained within the 90% isodose curves. The advantages of the technique are discussed, and survival rates given for different tumors at various stages of development.

    2001-02-01

    Intensive discussions within the OECD Support Group on 'VVER-440 Bubbler Condenser Containment Research Work' between 1991 and 1994 demonstrated the need for supplementary research work to achieve an adequate level of basic knowledge. In 1994, the European Commission (EC) asked for a specific 'VVER-440/213 Bubble Condenser Qualification Feasibility Study', which was finished early in 1996, confirming the need for additional research in this field. The Feasibility study formed the basis for the Bubble Condenser Experimental Qualification Project (BCEQ) with two separate experimental activities to be executed within the frame of the PHARE/TACIS 2.13/95 project of the European Commission. A first activity served to study the thermal-hydraulic phenomena and the associated structure dynamic interactions. This part of the project was performed at EREC, in Elektrogorsk, Russia. The design of the test facility was based on the prototypical bubbler condenser configuration for the Hungarian Paks nuclear power plant. A second activity addressed the structural integrity of certain components of the bubbler condenser steel structures under DBA-typical conditions. This part of the project was performed at VUEZ, in Levice, Slovak Republic. The design of the components of this facility was based on the structural properties of the Dukovany and/or Bohunice nuclear power plants. A third component of the BCEQ project was specified later asking for analytical studies, which should be supported by a number of small-scale separate effects tests to be performed at SVUSS, in Bechovice, Czech Republic. The main experimental and analytical results of the BCEQ test campaigns have been presented and discussed within the frame of the 4. meeting of the Technical Advisory Committee to the BCEQ (Bubble Condenser Experimental Qualification) Project in Brussels in December 1999 and on occasion of the 11. OECD Support Group Meeting in Berlin in April 2000. The discussions had evidenced several

  12. Sonification of network traffic flow for monitoring and situational awareness

    2018-01-01

    Maintaining situational awareness of what is happening within a computer network is challenging, not only because the behaviour happens within machines, but also because data traffic speeds and volumes are beyond human ability to process. Visualisation techniques are widely used to present information about network traffic dynamics. Although they provide operators with an overall view and specific information about particular traffic or attacks on the network, they often still fail to represent the events in an understandable way. Also, because they require visual attention they are not well suited to continuous monitoring scenarios in which network administrators must carry out other tasks. Here we present SoNSTAR (Sonification of Networks for SiTuational AwaReness), a real-time sonification system for monitoring computer networks to support network administrators’ situational awareness. SoNSTAR provides an auditory representation of all the TCP/IP traffic within a network based on the different traffic flows between between network hosts. A user study showed that SoNSTAR raises situational awareness levels by enabling operators to understand network behaviour and with the benefit of lower workload demands (as measured by the NASA TLX method) than visual techniques. SoNSTAR identifies network traffic features by inspecting the status flags of TCP/IP packet headers. Combinations of these features define particular traffic events which are mapped to recorded sounds to generate a soundscape that represents the real-time status of the network traffic environment. The sequence, timing, and loudness of the different sounds allow the network to be monitored and anomalous behaviour to be detected without the need to continuously watch a monitor screen.

    1991-01-01

    World petroleum demand is expected to increase from about 15 million barrels to 80 million after the year 2000. The resulting necessity to increase the currently over-extended global refining capacity will put a significant burden on financial resources within the industry. This article examines the developments, after a decade of restructuring, which have led to the present situation of the petroleum industry described as having greatly improved operational conditions but beset by worrisome problems with regard not only to capacity, but also to the costly constraints being imposed by new air pollution regulations, especially those relevant to desulfurization in refinery processes

    Nagra (the Swiss National Cooperative for the disposal of radioactive Waste) was established in 1972 by the Federal Government and the operators of nuclear power plants and is responsible for the safe disposal of all categories of radioactive waste in Switzerland. At present, Nagra does not have a permanent visitors centre as such, but this situation may change in the future with the selection of a site for a repository for short-lived wastes. One of our most important tasks is therefore to enhance the acceptance and understanding of radioactive waste management projects. We have to present the true facts; there is nothing to be achieved by manipulating or softening the message to be put across. When presenting information to the public we adhere to the strategy of communicating key points in the right way and at the right time in order to optimize impact

    1987-01-01

    Particle distributions, currents, and the ring current situation prior to the August 1984 launch of the AMPTE Charge Composition Explorer (CCE) are discussed. CCE results which demonstrate the capability of these new measurements to pursue questions of ring current sources, energization, and transport are presented. Consideration is given to various ring current generation mechanisms which have been discussed in the literature, and a two-step generation process which to a certain extent unifies the previous mechanisms is presented. The first in-situ global observations of ring current decay as obtained through the detection of energetic neutral atoms generated by charge exchange interactions between the ring current and hydrogen geocorona are discussed, as well as the possibility of using the detection of energetic neutral atoms to obtain global images of the earth's ring current.

  2. Testing Situation Awareness Network for the Electrical Power Infrastructure

    2016-09-01

    Full Text Available The contemporary electrical power infrastructure is exposed to new types of threats. The cause of such threats is related to the large number of new vulnerabilities and architectural weaknesses introduced by the extensive use of Information and communication Technologies (ICT in such complex critical systems. The power grid interconnection with the Internet exposes the grid to new types of attacks, such as Advanced Persistent Threats (APT or Distributed-Denial-ofService (DDoS attacks. When addressing this situation the usual cyber security technologies are prerequisite, but not sufficient. To counter evolved and highly sophisticated threats such as the APT or DDoS, state-of-the-art technologies including Security Incident and Event Management (SIEM systems, extended Intrusion Detection/Prevention Systems (IDS/IPS and Trusted Platform Modules (TPM are required. Developing and deploying extensive ICT infrastructure that supports wide situational awareness and allows precise command and control is also necessary. In this paper the results of testing the Situational Awareness Network (SAN designed for the energy sector are presented. The purpose of the tests was to validate the selection of SAN components and check their operational capability in a complex test environment. During the tests’ execution appropriate interaction between the components was verified.

    2002-01-01

    Thoughts on environmental actinides, especially transuranium elements, are presented with emphasis on present situation and future researches. It is since 1945 that man has been in direct relationship to the significant quantities of such transuranium elements, although Pu was discovered in 1942 to exist in very small quantities in nature. Substantial amounts of these elements (Np, Pu, Am) have been distributed in the environment mainly as the result of nuclear weapon testing, followed by accident of satellite and release of radioactive substances from nuclear facilities. Chernobyl nuclear power plant accident might serve as a most recent example of such release. Considerable efforts have been devoted to the investigation of the processes involved in the transfer of radionuclides in the environment and how these can be influenced. And, many data (levels and distribution) and knowledge to understand these processes have been obtained and accumulated. The final purpose in all the research was the protection of the human being. The present trends for environmental radioactivity research (or radioecology) involves a further development of models, speciation of radionuclides, tracer studies and countermeasures of other species than man in radiological protection. Joint researches between radioecologists and specialists such as meteorology, oceanography, geology, botany, statistics and so on are more and more needed to make one of the most fascinating environmental sciences. Finally, an effort should be made to develop radioecology into a more hypothesis-oriented science, as mentioned by Platt. (author)

    Manso, F.; Basso, A.

    1999-01-01

    Behavioural and karyotypical results from Anastrepha fraterculus samples received in our laboratory during the period 92-94 are discussed. The work represents the partial situation of this pest in Argentina. Data from guava fruits indicate 1) that the oviposition behaviour does not agree with the autocontrol mechanism via ODP previously described, 2) that a selection mechanism associated to fruit size and quality exists, allowing the female to choose the oviposition site, 3) if different varieties of fruits are available, then the fly shows preference for one of them. The oviposition behaviour in samples of peaches is different from that observed on guava samples and agrees with the ODP mechanism. In some localities, A. fraterculus and C. capitata share the same substrate or fruit (same unit). Samples from commercial oranges do not show evidence of Anastrepha attack. A more frequent karyotype fArg 1 (wild type karyotype) as well as high karyotypic variation, mainly measured through the polymorphism of sexual chromosomes, are present within different geographic populations sharing the same host species. To date, we do not have enough information to associate a particular behaviour to a karyotype. The chromosomal analysis is merely descriptive. (author)

    The main aim of this study is to overview the past and present situations of human taeniases and cysticercosis in Indonesia and including future perspectives. Through joint projects from 1996, we have confirmed the occurrence of Taenia saginata (beef tapeworm) in Bali, of Taenia solium (pork tapeworm) mainly in Papua and sporadically in Bali, and of Taenia asiatica in North Sumatra. These taeniases were caused through eating uncooked pork and pig viscera for T. solium and T. asiatica, respectively, and beef for T. saginata. The distribution of these tapeworms in Indonesia is basically highly restricted by the traditional cultural and religious backgrounds in each island. T. saginata is relatively common in Bali although people consume pork 'lawar' more than beef 'lawar'. Taeniases due to T. saginata or T. asiatica and T. solium and cysticercosis due to T. solium have also been sporadically reported in some other islands. Among these species, T. solium is exceptional since humans can be infected not only by larval stages (cysticerci) in pork but also by eggs released from human tapeworm carriers. Cysticercosis has been confirmed in Indonesia in humans, pigs and even dogs.

  8. Radioactive contamination in Arctic - present situation and future challenges

    International Nuclear Information System (INIS)

    Strand, Per

    2002-01-01

    There is currently a focus on radioactivity and the Arctic region. The reason for this is probably the high number of nuclear sources in parts of the Arctic and the vulnerability of Arctic systems to radioactive contamination. The Arctic environment is also perceived as a wilderness and the need for the protection of this wilderness against contamination is great. In the last decade information has also been released concerning the nuclear situation which has caused concern in many countries. Due to such concerns, the International Arctic Environmental Protection Strategy (IAEPS) was launched in 1991 and the Arctic Monitoring and Assessment Programme (AMAP) was established. AMAP is undertaking an assessment of the radioactive contamination of the Arctic and its radiological consequences. In 1996 IAEPS became part of the Arctic Council. AMAP presented one main report in 1997 and another in 1998. There are also several other national, bilateral and international programmes in existence which deal with this issue. This paper summarises some of current knowledge about sources of radioactive contamination, vulnerability, exposure of man, and potential sources for radioactive contamination within Arctic and some views on the future needs for work concerning radioactivity in Arctic.

    1979-01-01

    The present situation of the radiation exposure of workers, including both employes and subcontractors, in the nuclear power plants in Japan, is presented. Twenty seven nuclear power reactors in operation and under construction are tabulated with the name, the owner, the electric output and the commissioning year of each plant. The results of exposure of the workers in these plants are shown, classifying the dose rate into less than 0.5 rem, 0.5 - 1.5 rem, 1.5 - 2.5 rem, 2.5 - 5 rem and more than 5 rem, and the workers into employes and subcontractors. It is noted that the exposure dose of the subcontractors occupies about 88% of all exposure dose, and the exposure is concentrated during regular inspection period. The exposure dose of about 80% of the workers is less than 0.5 rem, and no one was irradiated more than 5 rem in a year. The total exposure dose, which has especially the tendency of increasing with extended maintenance period and decreasing during plant operation period, shows also the trend of increasing with the lapse of operation years. As for the point of view of whole exposure dose, the value is 0.06 -- 0.43 man-rem/10 6 kWh in 1976 FY. It is considered to be necessary to grasp the total exposure dose of each worker wandering from one plant to another, and the central registration center for the workers in radioactive environment was established in 1978. The whole exposure dose data of each worker are stored in the central computer in this center. This system is highly appreciated in radiation exposure management. The total exposure dose is related to the rate of utilization of nuclear plants, and it is expected to decrease with the decrease of plant outage. (Nakai, Y.)

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

    2012-09-01

    We are going to present a brief introduction to the OWL (Optical Wide-field patroL) network, one of Korean space situational awareness facilities. Primary objectives of the OWL network are 1) to obtain orbital information of Korean domestic LEOs using optical method, 2) to monitor GEO-belt over territory of Korea, and 3) to alleviate collisional risks posed to Korean satellites from space debris. For these purposes, we are planning to build a global network of telescopes which consists of five small wide-field telescopes and one 2m class telescope. The network of small telescopes will be dedicated mainly to the observation of domestic LEOs, but many slots will be open to other scientific programs such as GRB follow-up observations. Main targets of 2m telescope not only include artificial objects such as GEO debris and LEO debris with low inclination and high eccentricity, but also natural objects such as near Earth asteroids. We expect to monitor space objects down to 10cm in size in GEO using the 2m telescope system. Main research topics include size distribution and evolution of space debris. We also expect to utilize this facility for physical characterization and population study of near Earth asteroids. The aperture size of the small telescope system is 0.5m with Rechey-Cretian configuration and its field of view is 1.75 deg x 1.75 deg. It is equipped with 4K CCD with 9um pixel size, and its plate scale is 1.3 arcsec/pixel. A chopper wheel is employed to maximize astrometric solutions in a single CCD frame, and a de-rotator is used to compensate field rotation of the alt-az type mount. We have designed a compact end unit in which three rotating parts (chopper wheel, filter wheel, de-rotator) and a CCD camera are integrated, and dedicated telescope/site control boards for the OWL network. The design of 2m class telescope is still under discussion yet is expected to be fixed in the first half of 2013 at the latest. The OWL network will be operated in a fully

    2005-01-01

    The purpose of this study was to obtain a survey about the present situation including the usage pattern, technical characteristics and the anticipated future of teleradiology in Switzerland. An internet-based questionnaire was made available to all members of the Swiss Society of Radiology. Questions concerning current teleradiology usage, the type of transmitted modalities, the technology employed, security, billing issues and the anticipated future of teleradiology were addressed. One hundred and two (22.67%) of 450 radiologists responded to the survey. Of the total, 41.2% (42) were teleradiology users, 35.3% (36) planned to use teleradiology in the near future and 24.5% (25) did not use or plan to use teleradiology. The mean number of examinations transmitted per month was 198 (range 1-2,000) and the mean distance was 33 km (range 1,250 km). An emergency service was considered the most important purpose (mean score 6.90; minimum 1, maximum 10) for the use of teleradiology, followed by image distribution (mean 6.74) and expert consultation (mean 6.61). The most commonly transmitted modality was computed tomography (mean 8.80), followed by conventional X-rays (8.40) and magnetic resonance imaging (8.32). The most commonly transmitted format was Digital Imaging and Communications in Medicine (DICOM) (66.7%), followed by bitmap/Joint Photographic Experts Group (jpg) (38.1%), using the DICOM send/receive protocol (52.4%), followed by the hypertext transfer protocol (26.2%) and e-mail (21.4%). For security a secure connection (54.8%) followed by encryption (14.3%) and anonymization (9.5%) was used. For the future, image distribution was rated the most important aspect of teleradiology (7.88), followed by emergency (7.22) and expert consultation (6.53). Development of legal regulations is considered most important (8.17), followed by data security guidelines (8.15). Most radiologists believe that insurance companies should pay for the costs of teleradiology (37

    Full Text Available Achieving situation recognition in ubiquitous sensor networks (USNs is an important issue that has been poorly addressed by both the research and practitioner communities. This paper describes some steps taken to address this issue by effecting USN middleware intelligence using an emerging situation awareness (ESA technology. We propose a situation recognition framework where temporal probabilistic reasoning is used to derive and emerge situation awareness in ubiquitous sensor networks. Using data collected from an outdoor environment monitoring in the city of Cape Town, we illustrate the use of the ESA technology in terms of sensor system operating conditions and environmental situation recognition.

  17. On the present situation and future role of nuclear power

    International Nuclear Information System (INIS)

    1990-05-01

    The engaged public debate about the need for, and responsibility of, the continued use of nuclear power goes on unabated between the political parties and other groups of social relevance in the Federal Republic of Germany. And yet, some tentative changes seem to appear in the spectrum of opinions. In this situation, the German public utility companies operating nuclear power plants felt it necessary to express once more in a position paper their attitude with respect to nuclear power for the benefit of those bearing political responsibility at Federal and State Government level and the political parties. Their statements are guided by the responsibility the public utilities have for a reliable, sufficient, environmentally clean, and economic provision of electricity. They are convinced that nuclear power should remain a major constituent part of a comprehensive supply concept also in the future. This supply concept, which is based on the efficient use of power, relies on nuclear energy, run-of-river power, and lignite for the base load and on domestic hard coal for the medium load range; renewable energy sources are included. It underscores the social responsibility of the public utilities in ensuring electricity supply in a way which helps to conserve resources and is compatible with the environment. (orig.) [de

    Swiniarski, R. de

    2002-01-01

    Contrary to the general belief the nuclear medicine (NM) is a rather old science; actually, Henry Becquerel, the discoverer of the natural radioactivity in 1896, is deemed often as the initiator of this science and that would be the first stage. Discovery of artificial radioactivity by Irene and Frederic Joliot-Curie in 1934 marks the second essential stage and as such the initiation of NM. Nuclear medicine recorded significant progress since its inception, essentially after the WW1 due mainly to the advance of nuclear physics, nuclear electronics and the associated information techniques. But, the development of general physics boosted also other new methods of medical imaging as MRI (Magnetic Resonance Imaging), ultrasonic imaging, X-ray scanner, magnetic encephalography (MEG), etc. Several services of nuclear medicine currently functioning in France, in public or private hospitals, are all equipped at least with one Anger chamber, possibly two, what allows making the scintigraphy of most of human organs, or else, planar gamma-scintigraphy or tomo-scintigraphy. Unfortunately, regarding the positron chambers (positron computed tomography-PCT) the situation in France is not satisfactory. For the time being only three centres, particularly designed for research, are equipped with cyclotrons plus PCT technology, namely SHFJ at Orsay, Cyceron at Caen and SERMEP at Lyon (especially devoted to cardiologic investigation). Other two installations will be soon available at Toulouse and at Tenon (Paris). Officials, responsible of health services and medical schools and hospitals have defined a national index for PCT in France. Thus, starting from 2001, a machine for every million of inhabitants is provided, i.e. about 60 PCTs are planned to be installed till 2003 in Lille, Grenoble, Nantes, Rennes and other large French cities. France is committed not to miss the European bus of nuclear oncology of installing this equipment absolutely necessary in cancer detection and

    pathways were taken into account in assessing the doses to people in the identified settlements and the other areas. For the assessment of current doses it was assumed that people lived all year round in the settlements, that those in the vicinity of Lake Balapan spent one hour per day close to the lake and that those in the vicinity of Ground Zero spent one hour per day at the location. The preliminary conclusions are: No more detailed assessment of the radiological situation is required, because the doses today to local populations in the settlements are very low; Access to land with high dose rates within the polygon, namely Lake Balapan and Ground Zero, should be restricted in order to prevent reoccupation; Further specific and systematic studies are needed on the plutonium levels in the soil around Lake Balapan and Ground Zero, and on the levels of radionuclides in drinking water sources of the settlements outside the polygon

Finally, it focuses specifically on the assessment of the construct and provides a brief review of the general and psychometric characteristics of the instruments used in some of the most relevant national and international studies conducted on the subject. This work places special emphasis on the present and future challenges and concludes with a number of general recommendations intended to guide the correct selection and/or construction of assessment instruments in this field of study.

  4. Present Global Situation of Amino Acids in Industry.

    Science.gov (United States)

    Tonouchi, Naoto; Ito, Hisao

    At present, amino acids are widely produced and utilized industrially. Initially, monosodium glutamate (MSG) was produced by extraction from a gluten hydrolysate. The amino acid industry started using the residual of the lysate. The discovery of the functions of amino acids has led to the expansion of their field of use. In addition to seasoning and other food use, amino acids are used in many fields such as animal nutrients, pharmaceuticals, and cosmetics. On the other hand, the invention of the glutamate fermentation process, followed by the development of fermentation methods for many other amino acids, is no less important. The supply of these amino acids at a low price is very essential for their industrial use. Most amino acids are now produced by fermentation. The consumption of many amino acids such as MSG or feed-use amino acids is still rapidly increasing.

    It is reported that the most notable changes on the world energy scene since 1973 concerned the shift in OPEC's role from a base to a swing producer, the disruption of the fast market penetration of nuclear power and the impacts caused by the technical advances at essentially all stages of the energy system. Further, several parts of the world witnessed a strong environmental movement which attracted public attention to the conduct of the energy industry and its social implications and environmental consequences. The lecture illuminates these events in some detail and evaluate their impacts on present and future energy demand, supply and trade patterns. The future energy outlook includes two fundamentally different scenarios. Each scenario in itself appears internally consistent. The diverging projections of future energy demand and supply mixes underlying these scenarios are the result of the inclusion/omission of technical change or dynamics of technology into the analyses. 19 refs, 22 figs

    Hydropower is a clean and renewable energy source. Considering the economic, technical and environmental benefits of hydropower, most countries give priority to its development. China has the richest hydro resources on the planet with a total theoretical hydropower potential of 694 GW. Developing hydropower is of great importance to alleviate the energy crisis and environmental pollution resulting from the rapid economic growth of China in the 21st century. This paper provides a survey of hydropower development in China. Over the last five decades, China's hydropower has developed quickly. The installed capacity of hydropower is 145.26 GW presently. Some large hydropower plants have been in operation and many are still under construction, including the Three Gorges Project (TGP) and pumped-storage power stations. Small hydropower development accelerates rural electrification of this country. (author)

    The case of Forschungszentrum Karlsruhe is presented which had to transform from a centre devoted to nuclear power R and D to one in which this activity is allocated only 20% of the resources. A large number of operating nuclear power reactors coupled with the Government decision to phase out nuclear power is causing serious concerns regarding the availability of human resources for meeting the long term needs of nuclear facilities. The Energy Division of the research centre currently focuses mainly on safety research and on nuclear fusion. Another Division of the centre has nuclear facility decommissioning as one of the programmes. Independent research in areas of essential need for nuclear facilities must be carried out to maintain know how. (author)

    Full Text Available Las quinolonas son los antimicrobianos que han tenido un mayor desarrollo en los últimos años. Después de obtenerse el ácido nalidíxico, en 1962, se desarrollaron varios compuestos con características muy similares, que solo se establecieron como antisépticos urinarios, y que constituyeron la primera generación de quinolonas, hasta que en 1978, mediante la adición de un grupo piperacinil en posición 7 y un átomo de flúor en posición 6 comenzó a desarrollarse un conjunto de agentes antibacterianos llamados piperacinil fluoroquinolonas o simplemente fluoroquinolonas. El primero de ellos fue el norfloxacino, con el cual se logró una mayor actividad antimicrobiana del grupo y su uso sistémico. Durante años las fluroquinolonas fueron consideradas como un grupo homogéneo de antibióticos, con propiedades semejantes y, por tanto, como la segunda y última posibilidad de generación de quinolonas, pero las posibilidades de transformación de su estructura química ha producido un desarrollo vertiginoso de este grupo, que lo ha convertido en el más acelerado dentro de los antibióticos, con compuestos de mayor espectro antibacteriano, penetración tisular y seguridad, y con menor manifestación de resistencia antimicrobiana, demostrada hasta el presente, lo cual ha hecho que actualmente existan 4 generaciones de quinolonas, que se haya ampliado su uso y que continúe su desarrollo. Por tal motivo, se presenta una revisión que incluye espectro y mecanismo de acción, resistencia bacteriana, farmacodinamia y farmacocinética, interacciones medicamentosas, efectos adversos, indicaciones y dosificación de las más usadas.The quinolones are antimicrobial agents that have attained their highest development in the last years.

    Full Text Available The security incidents ion networks are sudden and uncertain, it is very hard to precisely predict the network security situation by traditional methods. In order to improve the prediction accuracy of the network security situation, we build a network security situation prediction model based on Wavelet Neural Network (WNN with optimized parameters by the Improved Niche Genetic Algorithm (INGA. The proposed model adopts WNN which has strong nonlinear ability and fault-tolerance performance. Also, the parameters for WNN are optimized through the adaptive genetic algorithm (GA so that WNN searches more effectively. Considering the problem that the adaptive GA converges slowly and easily turns to the premature problem, we introduce a novel niche technology with a dynamic fuzzy clustering and elimination mechanism to solve the premature convergence of the GA. Our final simulation results show that the proposed INGA-WNN prediction model is more reliable and effective, and it achieves faster convergence-speed and higher prediction accuracy than the Genetic Algorithm-Wavelet Neural Network (GA-WNN, Genetic Algorithm-Back Propagation Neural Network (GA-BPNN and WNN.

    The advantages of using hypothetical situations are one reason they have been widely used to examine adolescents' responses to conflict situations. One frequently used research protocol involves presenting several conflict scenarios to participants during a single session. However, in real-life situations multiple conflicts rarely occur within short periods of time, and the nature of this presentation may be associated with changes in adolescents' reports of conflict behaviors. Trend analyses of emotional, conflict goal, and conflict tactic responses from grade 8, 10, 12, and college students to consecutively presented conflict situations showed that responses were associated with presentation of the hypothetical situations. Findings revealed an increase in reports of assertive conflict behaviors and a decrease in reports of constructive conflict behaviors with successive situation presentation. Results from the current study suggest that researchers must consider trends in responses when examining findings from successive situation presentation methodologies because adolescent reports of conflict behavior may change as situation presentation proceeds.

    In 1989, a Radiological Transmission and Early Warning System (SYTAR) came into being in order to harmonize radioactivity surveillance methodologies and furthermore to trigger off an alert throughout the networks whenever an unusual degree of radioactivity is detected. SYTAR is a remote permanent system linking up a national electronic access and the radiation protection services of nuclear facilities located on the mainland. The structure of the network are particularly presented in the framework of a drill organized on october 1991 in the south-east of France. During this drill, an accident was simulated on a ghost nuclear power plant located in the Cadarache Nuclear Center. A large number of samples were taken from filtered aerosols, soils, grass, milk, vegetables, food stuff; they were contaminated with Caesium 137 and Iodine 131 before to be sent to laboratories for measurements. The results of measurements were transmitted to the actors of the drill using SYTAR network. They permit to determine the exclusion area, the radiological impacts and counter-measures. (author)

To solve the above questions, estimating parameters of super long situation sequence is essential, but very difficult, so this paper proposes a situation prediction method based on historical feature pattern extraction (HFPE). First, HFPE algorithm seeks similar indications from the history situation sequence recorded and weighs the link intensity between occurred indication and subsequent effect. Then it calculates the probability that a certain effect reappears according to the current indication and makes a prediction after weighting. Meanwhile, HFPE method gives an evolution algorithm to derive the prediction deviation from the views of pattern and accuracy. This algorithm can continuously promote the adaptability of HFPE through gradual fine-tuning. The method preserves the rules in sequence at its best, does not need data preprocessing, and can track and adapt to the variation of situation sequence continuously.

Successive reports have documented the fact that the current ad hoc unstructured management of this patient group is associated with considerable avoidable death and disability. The reform of trauma care in England, especially of the severely injured patient, has already begun. Strong clinical leadership is embraced as the way forward. The present article summarises the steps that have been made over the last decade that led to the recent decision to move towards a long anticipated restructure of the National Health Service (NHS trauma services with the introduction of Regional Trauma Networks (RTNs. While, for the first time, a genuine political will and support exists, the changes required to maintain the momentum for the implementation of the RTNs needs to be marshalled against arguments, myths and perceptions from the past. Such an approach may reverse the disinterest attitude of many, and will gradually evolve into a cultural shift of the public, clinicians and policymakers in the fullness of time.

    Zika virus infection is the present global problem. The infection is widely seen in tropical Latin and South American countries and results in several problems in that area. In addition, the previous big outbreak in many island countries in Pacific region brings attention to the further expansion of the infection worldwide. The specific situation of the infection in island countries is very interesting. Here, the current situation (in 2016) of Zika virus infection in Asian island countries in Indian Ocean is summarized and presented. Although there is still no current problem in the Asian island countries in Indian Ocean, the appearance of infection in the sea resorts of countries lining Indian Ocean is a big concern. Due to the high volume of traveler to sea resorts, emergence of the new disease in Asian island countries in Indian Ocean can be expected.

    2016-05-01

    The aim of this article is to present a situation of observation designed for the assessment of family interactions: The PicNic Game (PNG). In this situation, families are invited to play at having a picnic together. This can be done with any number of children, aged from a few weeks to adolescence. A companion assessment tool, the Revised-Picnic Assessment Scale (Re-PAS), allows evaluation of interactions in the family on several dimensions. This article presents the PNG and a preliminary study of the validation of the Re-PAS dimensions in a sample of families (N = 67) with 18-month-old infants and their siblings. The PNG was well-received by the families. Construct validity of the Re-PAS was tested, first against self-reported data by mothers and fathers regarding marital satisfaction, coparenting behavior, and division of household tasks, and then against observed maternal and paternal sensitivity and controlling behaviors assessed during free-play. Results show satisfactory preliminary reliability and validity. Two contrasting cases are presented to illustrate the different interactions highlighted in the PNG. This situation is useful for researchers and clinicians, particularly as a basis for video-feedback work with the family. © 2016 Michigan Association for Infant Mental Health.

    Gibson, William L [Los Alamos National Laboratory; Deborah, Leishman, A. [Los Alamos National Laboratory; Van Eeckhout, Edward [Los Alamos National Laboratory

    2008-01-01

    The authors have developed an enhanced Bayesian analysis tool called the Integrated Knowledge Engine (IKE) for monitoring and surveillance. The enhancements are suited for Rapid Response Situations where decisions must be made based on uncertain and incomplete evidence from many diverse and heterogeneous sources. The enhancements extend the probabilistic results of the traditional Bayesian analysis by (1) better quantifying uncertainty arising from model parameter uncertainty and uncertain evidence, (2) optimizing the collection of evidence to reach conclusions more quickly, and (3) allowing the analyst to determine the influence of the remaining evidence that cannot be obtained in the time allowed. These extended features give the analyst and decision maker a better comprehension of the adequacy of the acquired evidence and hence the quality of the hurried decisions. They also describe two example systems where the above features are highlighted.

  10. Radiation detection and situation management by distributed sensor networks

    2009-01-01

    Detection of radioactive materials in an urban environment usually requires large, portal-monitor-style radiation detectors. However, this may not be a practical solution in many transport scenarios. Alternatively, a distributed sensor network (DSN) could complement portal-style detection of radiological materials through the implementation of arrays of low cost, small heterogeneous sensors with the ability to detect the presence of radioactive materials in a moving vehicle over a specific region. In this paper, we report on the use of a heterogeneous, wireless, distributed sensor network for traffic monitoring in a field demonstration. Through wireless communications, the energy spectra from different radiation detectors are combined to improve the detection confidence. In addition, the DSN exploits other sensor technologies and algorithms to provide additional information about the vehicle, such as its speed, location, class (e.g. car, truck), and license plate number. The sensors are in-situ and data is processed in real-time at each node. Relevant information from each node is sent to a base station computer which is used to assess the movement of radioactive materials

    The author attempts to show the present situation (as of 1979/80) of the Austrian petroleum industry. Section two of the study is, to a certain extent, pointing out the range of activities of the OeMV-AG, which is the most important national petroleum company. Furthermore, the most important data and figures documenting the importance of petroleum and its processing products are mentioned in that section. In many countries the energy source petroleum contributes more than 50% to the total energy supply. Especially for this reason, it is necessary to attribute a certain weight to this energy source in making forecasts. This is considered in detail mainly in the third section, and apart from imports problems and environmental protection also the recent technologies in the field of petroleum production are described. The dissertation ends with a short view to the future energy situation and its problems.

    To analyze the access and accessibility to the healthcare network of women dwelling in rural contexts undergoing violence situation, as seen from the professionals' speeches. A qualitative, exploratory, descriptive study with professionals from the healthcare network services about coping with violence in four municipalities in the northern region of Rio Grande do Sul. The information derived from interviews, which have been analyzed by thematic modality. (Lack of) information of women, distance, restricted access to transportation, dependence on the partner and (lack of) attention by professionals to welcome women undergoing violence situation and (non)-articulation of the network are factors that limit the access and, as a consequence, they result in the lack of confrontation of this problem. To bring closer the services which integrate the confrontation network of violence against women and to qualify professionals to welcome these situations are factors that can facilitate the access and adhesion of rural women to the services.

    Full Text Available It is important to determine the security situations of the all-optical network (AON, which is more vulnerable to hacker attacks and faults than other networks in some cases. A new approach of the security situation assessment to the all-optical network is developed in this paper. In the new assessment approach, the evidential reasoning (ER rule is used to integrate various evidences of the security factors including the optical faults and the special attacks in the AON. Furthermore, a new quantification method of the security situation is also proposed. A case study of an all-optical network is conducted to demonstrate the effectiveness and the practicability of the new proposed approach.

  15. Further Questions: A Way Out of the Present Philosophical Situation (via Foucault

    Directory of Open Access Journals (Sweden)

    Leonard Lawlor

    2011-06-01

    Full Text Available Let us begin by assembling some signs of the present philosophical situation. On the one hand, the most important living French philosopher, Alain Badiou, calls for a “return to Plato,” despite the movement of anti-Platonism that dominated French and German thought in the 20th century. On the other hand, the present moment sees a resurgence of naturalism in philosophy in general (including and especially Anglophone analytic philosophy, despite the criticisms of naturalism that have appeared throughout the 20th century. Phenomenology seems to be at the center of both of these movements. On the one hand, it is the idea of a mathematized ontology that requires the return to Plato, a mathematized ontology constructed without a reflection on its transcendental grounds. On the other, the resurgence of naturalism is so strong that a book could be imagined and published with the bastard name of Naturalizing Phenomenology, as if the transcendental moment of phenomenology did not transform the very meaning of nature. These signs seem to indicate that we have entered into a phase of regression or even decline in philosophical thinking. If this interpretation of the signs is correct, if we have indeed entered into a phase of regression -- a twofold regression toward Platonism and toward naturalism -- we must ask the following question: is it possible for us to define something like a project or even a research agenda that would allow us to define a way of thinking that might lead us out of the present situation, a situation, it must be said, that seems dire for philosophy in general? If we can determine such a research agenda, perhaps we can also begin to understand what the tradition of “continental philosophy” has stood for.

    2017-09-01

    To prevent large interconnected power system from a cascading failure, brownout or even blackout, grid operators require access to faster than real-time information to make appropriate just-in-time control decisions. However, the communication and computational system limitations of currently used supervisory control and data acquisition (SCADA) system can only deliver delayed information. However, the deployment of synchrophasor measurement devices makes it possible to capture and visualize, in near-real-time, grid operational data with extra granularity. In this paper, a cellular computational network (CCN) approach for frequency situational intelligence (FSI) in a power system is presented. The distributed and scalable computing unit of the CCN framework makes it particularly flexible for customization for a particular set of prediction requirements. Two soft-computing algorithms have been implemented in the CCN framework: a cellular generalized neuron network (CCGNN) and a cellular multi-layer perceptron network (CCMLPN), for purposes of providing multi-timescale frequency predictions, ranging from 16.67 ms to 2 s. These two developed CCGNN and CCMLPN systems were then implemented on two different scales of power systems, one of which installed a large photovoltaic plant. A real-time power system simulator at weather station within the Real-Time Power and Intelligent Systems (RTPIS) laboratory at Clemson, SC, was then used to derive typical FSI results.

    Timonen, Jussi; Vankka, Jouko

    2013-05-01

    This paper presents a solution for information integration and sharing architecture, which is able to receive data simultaneously from multiple different sensor networks. Creating a Common Operational Picture (COP) object along with the base map of the building plays a key role in the research. The object is combined with desired map sources and then shared to the mobile devices worn by soldiers in the field. The sensor networks we used focus on location techniques indoors, and a simple set of symbols is created to present the information, as an addition to NATO APP6B symbols. A core element in this research is the MUSAS (Mobile Urban Situational Awareness System), a demonstration environment that implements central functionalities. Information integration of the system is handled by the Internet Connection Engine (Ice) middleware, as well as the server, which hosts COP information and maps. The entire system is closed, such that it does not need any external service, and the information transfer with the mobile devices is organized by a tactical 5 GHz WLAN solution. The demonstration environment is implemented using only commercial off-theshelf (COTS) products. We have presented a field experiment event in which the system was able to integrate and share real time information of a blue force tracking system, received signal strength indicator (RSSI) based intrusion detection system, and a robot using simultaneous location and mapping technology (SLAM), where all the inputs were based on real activities. The event was held in a training area on urban area warfare.

    The mission of I.R.S.N. concerns the metrology of ionizing radiation, the characterisation of exposure and the biological radiation effects, epidemiology, the management of data base, the means in emergency situation, the scientific networks for collaboration. The three directions of effort are: to improve the understanding of effects on man and ecosystems of chronic exposure of low level irradiation, prevention of risks linked to spiteful action, and the ability to answer in the case of radiological emergency, to contribute to evolution of practices in order to give the best possible expertise to workers at their occupational post or to patients in a medical frame. Three stakes emerge, the first one concerns the workers exposed to internal risks (inhalation of alpha emitters) and heterogenous external irradiation (doses at extremities), the second stake is the training of radiation protection actors, the third one is the knowledge of the history of doses received by workers and public because of ionizing radiations.

    A common assumption in organizations is that information sharing improves situation awareness and ultimately organizational effectiveness. The sheer volume and rapid pace of information and communications received and readily accessible through computer networks, however, can overwhelm individuals, resulting in data overload from a combination of diverse data sources, multiple data formats, and large data volumes. The current conceptual framework of network enabled operations (NEO) posits that robust networking and information sharing act as a positive feedback loop resulting in greater situation awareness and mission effectiveness in military operations (Alberts and Garstka, 2004). We test this assumption in a large-scale, 2-week military training exercise. We conducted a social network analysis of email communications among the multi-echelon Mission Command staff (one Division and two sub-ordinate Brigades) and assessed the situational awareness of every individual. Results from our exponential random graph models challenge the aforementioned assumption, as increased email output was associated with lower individual situation awareness. It emerged that higher situation awareness was associated with a lower probability of out-ties, so that broadly sending many messages decreased the likelihood of attaining situation awareness. This challenges the hypothesis that increased information sharing improves situation awareness, at least for those doing the bulk of the sharing. In addition, we observed two trends that reflect a compartmentalizing of networked information sharing as email links were more commonly formed among members of the command staff with both similar functions and levels of situation awareness, than between two individuals with dissimilar functions and levels of situation awareness; both those findings can be interpreted to reflect effects of homophily. Our results have major implications that challenge the current conceptual framework of NEO. In

    Full Text Available National Health Insurance (NHI in Korea has covered Korean medicine (KM services including acupuncture, moxibustion, cupping, and herbal preparations since 1987, which represents the first time that an entire traditional medicine system was insured by an NHI scheme anywhere in the world. This nationwide insurance coverage led to a rapid increase in the use of KM, and the KM community became one of the main interest groups in the Korean healthcare system. However, due to the public's safety concern of and the stagnancy in demand for KM services, KM has been facing new challenges. This paper presents a brief history and the current structure of KM health insurance, and describes the critical issues related to KM insurance for in-depth understanding of the present situation.

    Parnell, James Michael; Robinson, Jennifer C

    2018-06-01

    This paper introduces social network analysis as a versatile method with many applications in nursing research. Social networks have been studied for years in many social science fields. The methods continue to advance but remain unknown to most nursing scholars. Discussion paper. English language and interpreted literature was searched from Ovid Healthstar, CINAHL, PubMed Central, Scopus and hard copy texts from 1965 - 2017. Social network analysis first emerged in nursing literature in 1995 and appears minimally through present day. To convey the versatility and applicability of social network analysis in nursing, hypothetical scenarios are presented. The scenarios are illustrative of three approaches to social network analysis and include key elements of social network research design. The methods of social network analysis are underused in nursing research, primarily because they are unknown to most scholars. However, there is methodological flexibility and epistemological versatility capable of supporting quantitative and qualitative research. The analytic techniques of social network analysis can add new insight into many areas of nursing inquiry, especially those influenced by cultural norms. Furthermore, visualization techniques associated with social network analysis can be used to generate new hypotheses. Social network analysis can potentially uncover findings not accessible through methods commonly used in nursing research. Social networks can be analysed based on individual-level attributes, whole networks and subgroups within networks. Computations derived from social network analysis may stand alone to answer a research question or incorporated as variables into robust statistical models. © 2018 John Wiley & Sons Ltd.

    2011-10-11

    Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls.

    For purpose of investigating the present situation of radiological technologist education for radiation protection and control before leaving school, questionnaires were sent out to 28 school for radiological technologist in Japan. For purpose of characterizing each school, it is permitted by the 'Designation rules for schools and training schools for radiological technologist' to use 500 school hours for any of the subject, mainly special subjects that are selected by the school. In investigating the 500 school hours which are left to the discretion of each school for characterization, some of those hours are used for radiation control-related subjects in 20 schools from which answers to questionnaires were obtained. Briefly, 15 to as many as 210 hours are spent for lessons regarding such subjects. (author)

    With the restart-up of Browns Ferry NPP on May 22, 2007, the US nuclear park comprises now 104 reactors in operation: 35 BWR-type and 69 PWR-type. NPPs are present in only 31 states and mainly in the eastern half of the country. Nuclear energy represents 20% of the US energy mix (coal: 50%, gas: 19%, hydro-power: 6%, petroleum: 3% and other renewable energies: 2%). The highest average availability rate in power generation is reached by nuclear energy (89.9%). The nuclear power generation reached 787.2 TWh in 2006, i.e. the second best result after the 2004 record (788.5 TWh). This document presents also some nuclear safety and radioprotection indicators (number of unplanned outages, failures, injury frequency rate), the programme of licenses extension, the permissions for power increase, the demands for design certification, for early site permit, and for combined construction permit and operating license. The regulation may be different from one state to the other and sometimes not favorable to a re-launch of nuclear energy. The situation of each state in this domain is presented in appendix. (J.S.)

  8. Do power lines and protected areas present a catch-22 situation for Cape vultures (Gyps coprotheres)?

    2013-01-01

    Cape vulture Gyps coprotheres populations have declined across their range due to multiple anthropogenic threats. Their susceptibility to fatal collisions with the expanding power line network and the prevalence of carcasses contaminated with illegal poisons and other threats outside protected areas are thought to be the primary drivers of declines in southern Africa. We used GPS-GSM units to track the movements and delineate the home ranges of five adult (mean ±SD minimum convex polygon area = 121,655±90,845 km(2)) and four immature (mean ±SD minimum convex polygon area = 492,300±259,427 km(2)) Cape vultures to investigate the influence of power lines and their use of protected areas. The vultures travelled more than 1,000 km from the capture site and collectively entered five different countries in southern Africa. Their movement patterns and core foraging ranges were closely associated with the spatial distribution of transmission power lines and we present evidence that the construction of power lines has allowed the species to extend its range to areas previously devoid of suitable perches. The distribution of locations of known Cape vulture mortalities caused by interactions with power lines corresponded to the core ranges of the tracked vultures. Although some of the vultures regularly roosted at breeding colonies located inside protected areas the majority of foraging activity took place on unprotected farmland. Their ability to travel vast distances very quickly and the high proportion of time they spend in the vicinity of power lines and outside protected areas make Cape vultures especially vulnerable to negative interactions with the expanding power line network and the full range of threats across the region. Co-ordinated cross-border conservation strategies beyond the protected area network will therefore be necessary to ensure the future survival of threatened vultures in Africa.

  9. Present situation and future prospects of electricity generation in Aegean Archipelago islands

    Kaldellis, J.K.; Zafirakis, D.

    2007-01-01

    The Aegean Archipelago is a remote Hellenic area, including several hundreds of scattered islands of various sizes. In these islands more than 600,000 people are living mainly in small remote communities. The main economical activities of the islanders are apart from tourism, seafaring, fishery, agriculture and stock farming. One of the major problems of the area is the insufficient infrastructure, strongly related with the absence of an integrated and cost-effective electrification plan. In this context, the present work is concentrated on analyzing the present situation and demonstrating the future prospects of electricity generation in the Aegean Archipelago islands. For this purpose, one should first investigate the time evolution of the corresponding electricity generation parameters (i.e. annual electricity consumption, peak power demand, capacity factor, specific fuel consumption) for the last 30 years. Subsequently, the corresponding diesel and heavy-oil consumption along with the electricity production cost for every specific autonomous power station of the area are investigated. Special attention is paid in order to estimate the contribution of renewable energy sources (RES) in the energy balance of each island. Finally, an attempt is made to describe in brief the most realistic electricity production solutions available, including the operation of hybrid RES-based power plants in collaboration with appropriate energy storage facilities. Additionally, the idea of connecting the islands of the area with the mainland and interconnecting them is also taken into consideration

    Full Text Available Abstract OBJECTIVE To learn the conceptions and actions of health professionals on the care network for women in situations of violence. METHOD A qualitative, descriptive, exploratory study was conducted between April and July 2015 with the participation of 21 health professionals from four primary health care teams in a city of the central region of the state of Rio Grande do Sul. Data were collected by means of individual semi-structured interviews. Content analysis was used for data systematization. RESULTS Health professionals recognized the importance of the health care network for coping with the problem of violence against women. However, their conceptions and actions were limited by the discoordination or absence of integration among professionals and services of the care network.

    Many existing results on fault-tolerant algorithms focus on the single fault source situation, where a trained network is affected by one kind of weight failure. In fact, a trained network may be affected by multiple kinds of weight failure. This paper first studies how the open weight fault and the multiplicative weight noise degrade the performance of radial basis function (RBF) networks. Afterward, we define the objective function for training fault-tolerant RBF networks. Based on the objective function, we then develop two learning algorithms, one batch mode and one online mode. Besides, the convergent conditions of our online algorithm are investigated. Finally, we develop a formula to estimate the test set error of faulty networks trained from our approach. This formula helps us to optimize some tuning parameters, such as RBF width.

    Full Text Available The article discusses analyses and assesses the key proposals how to deal with the situation identification for the heterogeneous service support in vehicular cooperation environment. This is one of the most important topics of the pervasive computing. Without the solution it is impossible to adequately respond to the user's needs and to provide needed services in the right place at the right moment and in the right way. In this work we present our developed real time situation identification model for adaptive service support in vehicular communication networks domain. Our solution is different from the others as it uses additional virtual context information source - information from other vehicles which for our knowledge is not addressed in the past. The simulation results show the promising context exchange rate between vehicles. The other vehicles provided additional context source in our developed model helps to increase situations identification level.

    Full Text Available The research aimed to explore the present situation of the internal quantitative efficiency of Sanhan community college, and to identify the annual cost per student and material waste resulting from failure and dropout. The study depended primarily on the method of restructuring the study life in order to measure the internal efficiency of quantitative indicators for the college.  This was done by building the chart structure of student flow, which allows calculating success rate, failure rate, and the dropout rate for each batch. This enabled the researchers to calculate the indicators of internal quantity efficiency and its level. The study results revealed that the educational system in Sanhan Community college has not reached the required standard, which impacted  the internal quantitative efficiency. In addition, the proportion of quantitative loss resulting from students’ failure and dropout was (50%. Some recommendations were also proposed in order to raise the efficiency and effectiveness level so as to reach the desired standard. Keywords: Internal quantity efficiency, Sanhan Community College, Yemen.

    Field missions were sent to the Semipalatinsk regions to investigate the present radioecological situation as a result of the radioactive fallout from nuclear test explosions carried out at the former Soviet Union's Semipalatinsk nuclear test site (SNTS). For this purpose, surface and core soil samples were collected at more than 60 sites, including several settlements such as Dolon, Chagan and Sarzhal, within and outside the SNTS territory. The radioactivities of long-lived radionuclides, 137 Cs, 238 Pu and 239,240 Pu, and the atomic ratio of 240 Pu/ 239 Pu were determined in combination with non-destructive g-ray spectrometric method and radiochemical separation followed by a-particle spectrometric and/or ICP-MS methods. The results showed a distinction of 137 Cs and 239,240 Pu inventories in soil depending on a sampling sites. Although 137 Cs was within typical environmental levels except for the area near the first nuclear test site and Balapan, 239,240 Pu was at elevated levels in all areas we visited. This high Pu contamination was recognized to be due to the weapons-grade Pu from the SNTS by the measurement of 240 Pu/ 239P u atomic ratio in soil samples. (author)

    Auriol, P.

    1988-01-01

    Mediterranean countries as a whole suffer from a chronic shortage of livestock products, the main reason being the acceleration in demand observed since World War II. This acceleration has been caused by the combination of high rates of population growth and rapid increases in per capita incomes which have gone hand-in-hand with rapid urbanization. The particularly high income elasticity for livestock products has aggravated the situation. The most important constraints on livestock development are the limited amount of feed resources and their seasonality. The introduction of already known techniques and the active search for new ones leave room for substantial development. However, their adoption by the mass of producers will depend on the supply by governments of support services and on a general increase in producer prices for livestock versus plant products. Considering the diminishing political influence of farmers, such an increase can be envisaged only within the context of healthy and expanding national economies and where governments favour indigenous livestock production. In other words, livestock sectors will expand only if national economies recover rapidly from the present world crisis and if governments are able to create a socio-economic environment stimulating livestock producers.

  16. Modeling Air Traffic Situation Complexity with a Dynamic Weighted Network Approach

    Directory of Open Access Journals (Sweden)

    Hongyong Wang

    2018-01-01

    Full Text Available In order to address the flight delays and risks associated with the forecasted increase in air traffic, there is a need to increase the capacity of air traffic management systems. This should be based on objective measurements of traffic situation complexity. In current air traffic complexity research, no simple means is available to integrate airspace and traffic flow characteristics. In this paper, we propose a new approach for the measurement of air traffic situation complexity. This approach considers the effects of both airspace and traffic flow and objectively quantifies air traffic situation complexity. Considering the aircraft, waypoints, and airways as nodes, and the complexity relationships among these nodes as edges, a dynamic weighted network is constructed. Air traffic situation complexity is defined as the sum of the weights of all edges in the network, and the relationships of complexity with some commonly used indices are statistically analyzed. The results indicate that the new complexity index is more accurate than traffic count and reflects the number of trajectory changes as well as the high-risk situations. Additionally, analysis of potential applications reveals that this new index contributes to achieving complexity-based management, which represents an efficient method for increasing airspace system capacity.

    This article presents information on the environmental hazards prevailing in Somalia and recommends a health prophylaxis in connection with a potential deployment of Polish Military Contingent to this part of the world. Somalia is a country located in the eastern part of Africa, in the so-called Horn of Africa. The country has been continuously at war for over two decades. Because of its much-devastated municipal and industrial infrastructure, widespread famine and limited access of the local people to healthcare it is considered one of the countries where living conditions are extremely difficult. Epidemiological indexes in Somalia are the worst in the world, and the Somali citizens are entirely dependent on foreign humanitarian assistance. At present, three different military operations, under the auspices of international organizations, have been carried out on the soil and the territorial waters: the European Union Naval Force Somalia--Operation Atlanta, the NATO Operation Ocean Shield, and the biggest of the three--the UN peacekeeping mission AMISOM with 9,5 thousand African troops, mainly from Uganda and Burundi). Despite their presence, the situation of the civilian population is critical. If the number ofpeacekeeping and stabilization troops deployed to the Horn of Africa is increased, it is very likely that Polish soldiers will also get involved in the military operations in Somalia. because of a strong possibility that following European military contingents are going to be relocated to East Africa to carry out the mandatory tasks, in relation to the occurrence of difficult climatic conditions and low sanitary standards, it is necessary to undertake appropriate preventive measures before the departure (compulsory/recommended vaccinations, antimalarial chemoprophylaxis, stocks of medicines to be taken by soldiers for an extended period of time, prevention and treatment kits), throughout the deployment (acclimatization, avoiding alcohol, water and

  18. NATURE CONSERVATION MOVEMENT IN THE WORLD: ITS HISTORICAL DEVELOPMENT AND PRESENT SITUATION

    Full Text Available Although nature conservation is a well recognized topic at present, it is not a new phenomenon. Throughout history, there are numerous examples of efforts made by governments, rulers, or individual land owners to protect certain land areas that possessed unique natural values. While many of these areas were actually isolated as game preserves for hunting, they were also designed to conserve wildlife. The establishment of Yellowstone National Park in 1972 marks the modern concept of a national park as it was designed on a very large protected natural area. Presently, one of the most efficient ways for nature protection is “area conservation approach” that many organizations have been developing various systems and categories about. Unfortunately, in spite of such improvements and the extension of the protected area network, many of these areas are not properly protected and/or managed in some countries. This study summarizes the historical evolution of nature conservation systems and strategies in the world with the related international legislative aspects as well. As it stated in this paper, USA and Europa have a well known history on nature conservation and show great concern in respect to participating to the international convention and arrangements.

  19. Present situation of Japan's public acceptance of nuclear energy - JAERO's activities

    Electricity demand in Japan is expected to keep increasing without doubt, reflecting her constant economic growth and the rising living standard of the people. The target figure is 20.5% or a capacity of 52 million kW, and 11 nuclear power plants with a capacity of 12 million kW are under construction. Whether such a target is achievable depends on whether or not information activities will succeed in obtaining public consensus to the siting of the new nuclear power plants. According to the result of public opinion poll by the Science and Technology Agency in 1992, 73 % people recognize the necessity of nuclear energy, however, 10% feel uneasy as well. It seems that the scale of damage caused by severe accidents and the distrust against nuclear promoters are major factors to create uneasiness among the people. This presentation describes public information activities by JAERO, the Japan Atomic Energy Relations Organization (JAERO), a non-profit organization established in 1969. There is no secret strategy or specific remedy to obtain public consensus on the nuclear issues, and an immediate effect is in no way expected, either. It is all the more imperative to enhance the safety of nuclear power plants, pursue further the operational safety, and to gain the trust from the general public. We must investigate more effective means for public information activities to gain public consent, and implement them positively and continuously with beliefs. We are prepared to do so. Activities for public acceptance of nuclear energy may vary in line with the situation in each country. It is therefore very meaningful to have the experts' gatherings like this workshop to exchange, views on the public acceptance

    The report contains a general overview of present technology concerning production of biogas through anaerobic breakdown of easily recycled organic material as well as implementation areas for biogas. The work has been done in three parts: description of present situation, technical limitations and development efforts, synthesis. In Sweden there are more than 220 biogas plants for handling crops, sludge and organic residue material. Production of biogas occurs primarily at sewage treatment plants and landfills. Total capacity in 2004 was approx. 300,000 m{sup 3} anaerobic chamber volume, of which approx. 73% was utilised. Planned increase in capacity was approx. 125,000 m{sup 3} or approx. 42%.The substrate brought to the plants was comprised of approx. 45% manure, 30% offal, 10% biowaste from households and 15% other substrates. Calculations based on the energy content of input substrate indicate that approx. 10% of the gas was from manure, 65% from offal, 25% from household waste and 5% from other substrates. In 2005 a total of 1,5 TWh of biogas was produced in Sweden. Biogas is used primarily for heating purposes followed by use as vehicle fuel and in electricity production. More than 55 GWh is torched away. Sewage treatment plants are not included. Interest in using biogas as fuel has increased. The theoretical biogas potential in Sweden has been calculated to be 14-17 TWh per year, of which approx. 80% is found in agriculturally related biomass. Approximately 3 TWh originates from various types of household and industrial waste. Generally it can be said that there is a large potential for improvement and increased efficiency within the whole chain of substrate collection, preparatory treatment of substrates, operational control of biogas plants, upgrade/treatment and use of gas as well as spreading and use of biofertilizer. The greatest increase in substrate will come from the amount of crops from the agricultural sector. The contacts between farmers and plant

    Full Text Available We already acepted that Croatian economical and geopolitical possition can bee improved only with better utilization of coastal area. Under these conditions mariculture also makes a part od sea master plan because demands for mariculture are focused on clean environmental conditions to obtain economic benefits. Increased pressure to the coastal area is global trend and if not planed and organized can provoke conflicts and can affect further development. Under these condition, marine aquaculture is frequent subject of many discussion focused on the environmental impact. Conflict of different interest in coastal area with no argumentation is putting marine aquaculture in worst position related with tourism and industry. Hard argumentations is laying in noneadequate frame of work in some facilities and to take advantake competitors are preasenting marine aquaculture in worst picture. Marine aquaculture product has to be health product, which can be completely damaged because of non-responsible approach of other activity. Mariculture also can suffer from self-pollution as for example tourism and must be well planed and managed. Fecal pollution from towns, pollution from bad controlled tourists activity, industry, influence of intensive and non controlled agriculture in coast line, are also potential danger for quality of all sea products and also cultured products from marine aquaculture. High quality of marine products can be obtained by zoning of coastal area, and in concept of these zoning it is necessary to define the zones for marine aquaculture. Procedure of zoning has to be divided in three steps: deetrmination of present status of area, definition of shore land for making mariculture related shore infrastructure and definitions of areas suitable for mariculture with limits of production. These can make positive situations with avoiding conflicts in exploitation of common resources in future. Zone for marine aquaculture has to be controlled

    1998-01-01

    At present there are 3 facilities (polygons) for the deep-well injection of liquid radioactive waste in Russia, all of which were constructed in the mid60's. These facilities are operating successfully, and activities have started in preparation for decommissioning. Liquid radioactive waste is injected into deep porous horizons which act as 'collector-layers', isolated from the surface and from groundwaters by a relatively thick sequence of rock of low permeability. The collector-layers (also collector-horizons) contain salt waters or fresh waters of no practical application, lying beneath the main horizons containing potable waters. Construction of facilities for the deep-well injection of liquid radioactive waste was preceded by geological surveys and investigations which were able to substantiate the feasibility and safety of radioactive waste injection, and to obtain initial data for facility design. Operation of the facilities was accompanied by monitoring which confirmed that the main safety requirement was satisfied i.e. localisation of radioactive waste within specified boundaries of the geologic medium. The opinion of most specialists in the atomic power industry in Russia favours deep-well injection as a solution to the problem of liquid radioactive waste management; during the period of active operation of defence facilities (atomic power industry of the former U.S.S.R.), this disposal method prevented the impact of radioactive waste on man and the environment. The experience accumulated concerning the injection of liquid radioactive waste in Russia is of interest to scientists and engineers engaged in problems of protection and remediation of the environment in the vicinity of nuclear industry facilities; an example of the utilisation of the deep subsurface for solidified radioactive waste and the disposal of different types of nuclear materials.

    Full Text Available In this study we critically review the internal procedures of the accounting community for generating and disseminating knowledge. We contend that academic journals on accounting research are scarce, publish few articles and apply high rejection rates, and the review process is lengthy and expensive. Additionally, an academic elite has unparalleled predominance in comparison to other business disciplines, reflected in an unusual share of published articles with authors affiliated to a small number of academic institutions, and the predominance of certain topics and methodologies. The discipline does not allow the collaborative, iterative and flexible features of innovative knowledge communities. The discipline’s internal procedures favour restriction, control, slowness, and expiration, rather than participation, speed and renewal. They are ill suited for advancing knowledge and bode badly for successful research. As a result, accounting academics present low research performance and the discipline is facing steady decline. More importantly, the discipline is handicapped in producing innovative knowledge able to contribute to critical research and long term social well-being.We also focus on the Spanish institutional situation, arguing that Spanish requirements for reaching tenured positions are difficult for accountants to meet.We highlight the need to raise awareness of the problem and change the procedures.En este estudio hacemos una revisión crítica de los procedimientos vigentes en la comunidad académica contable para la generación de conocimiento y su publicación. Exponemos que hay pocas revistas académicas para publicar la investigación contable, que éstas publican pocos artículos, aplican elevadas tasas de rechazo y el proceso de revisión es lento y costoso. Además, hay un predominio de una elite académica sin precedentes en otras disciplinas de empresa, lo cual se refleja en un mayor porcentaje de artículos pertenecientes

    The area of Disaster Management is well established among Federal Agencies such as FEMA, EPA, NOAA and NASA. These agencies have well formulated frameworks for response and mitigation based on near real time satellite and conventional observing networks for assimilation into geophysical models. Forecasts from these models are used to communicate with emergency responders and the general public. More recently, agencies have started using social media to broadcast warnings and alerts to potentially affected communities. In this presentation, we demonstrate the added benefits of mining and assimilating the vast amounts of social media data available from heterogeneous hand held devices and social networks into established operational geophysical modeling frameworks as they apply to the five cornerstones of disaster management - Prevention, Mitigation, Preparedness, Response and Recovery. Often, in situations of extreme events, social media provide the earliest notification of adverse extreme events. However, various forms of social media data also can provide useful geolocated and time stamped in situ observations, complementary to directly sensed conventional observations. We use the concept of a Human Sensor Network where one views social media users as carrying field deployed "sensors" whose posts are the remotely "sensed instrument measurements.' These measurements can act as 'station data' providing the resolution and coverage needed for extreme event specific modeling and validation. Here, we explore the use of social media through the use of a Human Sensor Network (HSN) approach as another data input source for assimilation into geophysical models. Employing the HSN paradigm can provide useful feedback in near real-time, but presents software challenges for rapid access, quality filtering and transforming massive social media data into formats consistent with the operational models. As a use case scenario, we demonstrate the value of HSN for disaster management

    New trends of nuclear science and engineering - radiation engineering and radiation technology - have emerged because of the large scale industrial production of artificial radioactive isotopes as well as of the manufacture of electrophysical sources of ionizing radiation. Over 3,500 isotope articles consumed by more than 15,000 enterprises are now manufactured in the USSR. The new trends have subsequently converted into individual branches of the nuclear science and engineering, without which the future technical progress in various fields of industry, medicine, agriculture and scientific research is impossible. Reviewing the situation and trends in the USSR, the following matters are described: tracer method, radiation instrumentation, radiation flaw detection, radiation technology, radiation sterilization, radiation polymerization, radiation modification, radiation and chemical synthesis, food preservation, radiation therapy, radioisotope power engineering.

    1991-09-01

    The World Health Organization does not give any data on the malaria situation in Africa in its regular reports because of the "insufficiency and irregularity of reporting". Estimates on the total number of cases and the number of deaths vary considerably. They range from 35 million to 189 million per year depending on whose figures one uses. An intensive search of the literature using computer-based systems identified more than 1000 titles on the epidemiology of malaria. Out of them and from other sources finally 426 articles were used to describe the current malaria situation and observable trends in Africa. Major findings were that malaria is responsible for about 40% of fever cases, mortality is about 5 per 1000 per year, case fatality ranges from 2% to 24%. Admissions for malaria account for 20% to 50% of all admissions in African health services although only 8% to 25% of persons with malaria visit health services. Self-treatment is more common in urban areas (more than 60%) but an increasing number of people use some form of self protection in rural areas (2% to 25%). The resistance of malaria parasites to chloroquine and other drugs is widespread. Chloroquine resistance has reached a prevalence of about 30% at the RII level in most countries. Malaria incidence shows annual growth rates of 7.3% for Zambia, 10.4% for Togo, and 21.0% for Rwanda. The data for Burkina Faso show a downward trend of--14.7% during the years from 1973 to 1981. Since then malaria incidence is increasing at 11.0% per year. Hospital data reported from Zambia indicate that mortality is rising 5.2% per annum in children and 9.7% per annum in adults. Reasons for the increase of malaria and its role for development are discussed.

    Full Text Available Historically and culturally, water has always been considered to be a critical issue in Mexico- USA agenda. Along the 3 140-km border between Mexico and the United States, there is intense competition over the adequate availability of water. Water uses in urban border areas have continued to increase exponentially due to steadily increasing levels of population growth. Rapid industrialisation and urbanisation have resulted in more intensive patterns of water consumption and use. Agricultural water demands continue to be high. Mexico and the United States have established institutions and agreements to manage and protect rivers in the border region. The Treaty between Mexico and the United States for the Utilisation of Waters of the Colorado and Tijuana Rivers and of the Rio Grande was signed in 1944. With the turn of the century, the growing urban centers along the Rio Grande (Rio Bravo, where the river becomes the international boundary, started increasingly to depend on groundwater. This situation was not specifically addressed in the 1944 Treaty, especially as groundwater use at that time was not so significant.

    Full Text Available The past decade has witnessed increased globalization of the world economy as result of technological changes, trade liberalization and privatization policies. Balkan countries as developing nations are in the realization process of the globalization changes of the world economy. Being in the process for entry into the EU, many changes are being done to integrate with the global economic trends. The research has shown that after the fall of communism in the 1990s the Balkan Region brought significant political and economic changes. The change in attitude led to a removal of direct blockage for FDI. As a result, continued deregulation and privatization has been widespread. However, history of FDI is relatively short for Balkan Region in comparison with other countries. The economy opened up capital inflows only at the beginning of 1990s, and is still showing low shares in the total of Central and Eastern European flow. Despite Balkans competitive advantage due to its geographical location and its resources, it is still far from other Central European countries in achieving the same level of FDI. This situation came as a result of: political instability, low intraregional trade, the small size of national markets, huge institutional corruption and weak judiciary system. Among the more successful Balkan recipients of FDI has been Bulgaria and Romania, while Greece has been a major source of FDI for the transition economies of the Balkan region. Greek investment is driven in part by the availability of low cost labor in the nearby transition economies. The focus of this article is to analyze and evaluate the current performance of FDI in Balkan Region and how the governments can improve this performance.

    The theme of the conference, 'Political and Technical Progress of Geologic Repositories', has drawn world-wide attention and remains a challenging topic facing the nuclear industry. I am delighted to attend this important conference and have the opportunity to state our views. And I would like to express my gratitude to our host Sweden and IAEA. The development of nuclear science and technology and the peaceful uses of nuclear energy is one of the greatest achievements of the mankind in the 20. century. The development and progress of nuclear technology, from application of fission energy to the exploration of fusion energy, embodies the mankind's expectation to the future. It will be the major energy of final settlement of the issue of global sustainable development. The safe and effective treatment and disposal of nuclear waste are of vital importance to the peaceful uses of nuclear energy and technology. The most dangerous and long-lived waste has to be contained and isolated from the human living environment. Construction of geologic repository in appropriate geological formation for radioactive waste disposal is being accepted as a suitable solution and being studied widely. In the International Conference on Geological Repositories held in Denver, U.S.A., in November 1999, senior governmental representatives from more than 20 countries stated related policies and decisions of their respective countries, which caught world-wide attention. I am convinced that this conference, an event about geologic repository following the Denver conference, will produce positive results for the safe and effective disposal of nuclear waste. Now I would like to take this opportunity to brief you on China's current situation and perspectives of geologic disposal of high-level radioactive waste. (author)

    Full Text Available Objectives: Functional magnetic resonance imaging (fMRI is a reliable and non-invasive method with which to localize language function in pre-surgical planning. In clinical practice, visual stimulus presentation is often difficult or impossible, due to the patient’s restricted language or attention abilities. Therefore, our aim was to investigate modality-specific differences in visual and auditory stimulus presentation.Methods: Ten healthy subjects participated in an fMRI study comprising two experiments with visual and auditory stimulus presentation. In both experiments, two language paradigms (one for language comprehension and one for language production used in clinical practice were investigated. In addition to standard data analysis by the means of the general linear model (GLM, independent component analysis (ICA was performed to achieve more detailed information on language processing networks.Results: GLM analysis revealed modality-specific brain activation for both language paradigms for the contrast visual > auditory in the area of the intraparietal sulcus and the hippocampus, two areas related to attention and working memory. Using group ICA, a language network was detected for both paradigms independent of stimulus presentation modality. The investigation of language lateralization revealed no significant variations. Visually presented stimuli further activated an attention-shift network, which could not be identified for the auditory presented language.Conclusion: The results of this study indicate that the visually presented language stimuli additionally activate an attention-shift network. These findings will provide important information for pre-surgical planning in order to preserve reading abilities after brain surgery, significantly improving surgical outcomes. Our findings suggest that the presentation modality for language paradigms should be adapted on behalf of individual indication.

    The awareness of the need to preserve the environment in the local, regional and international spheres has produced a large number of control and prevention rules that constitute the Environmental Law. The contamination of the sea has been the last field to be considered by the States. Since few years ago, marine pollution is appraised as an issue that affects all the States, taking account of its interdependency and the need to establish between governments a greater cooperation network. The radioactive contamination, i.e. the pollution produced by the discharge of radioactive wastes into the sea, is one of the types of contamination. Several discharge systems have been designed, so it is necessary to select in each case the most suitable one taking into account the type of wastes and other factors as the economy and the effectiveness of the method and the application of the radiation protection principles. International rules have evolved to solve different issues since the first United Nation Convention on the Law of the Sea in 1945 to the third Conference in 1982 that produced the United Nation Convention on the Law of the Sea and four Resolutions.

    Recent research has shown that the ubiquitous use of cameras and voice monitoring equipment in a home environment can raise privacy concerns and affect human mental health. This can be a major obstacle to the deployment of smart home systems for elderly or disabled care. This study uses a social robot to detect embarrassing situations. Firstly, we designed an improved neural network structure based on the You Only Look Once (YOLO) model to obtain feature information. By focusing on reducing area redundancy and computation time, we proposed a bounding-box merging algorithm based on region proposal networks (B-RPN), to merge the areas that have similar features and determine the borders of the bounding box. Thereafter, we designed a feature extraction algorithm based on our improved YOLO and B-RPN, called F-YOLO, for our training datasets, and then proposed a real-time object detection algorithm based on F-YOLO (RODA-FY). We implemented RODA-FY and compared models on our MAT social robot. Secondly, we considered six types of situations in smart homes, and developed training and validation datasets, containing 2580 and 360 images, respectively. Meanwhile, we designed three types of experiments with four types of test datasets composed of 960 sample images. Thirdly, we analyzed how a different number of training iterations affects our prediction estimation, and then we explored the relationship between recognition accuracy and learning rates. Our results show that our proposed privacy detection system can recognize designed situations in the smart home with an acceptable recognition accuracy of 94.48%. Finally, we compared the results among RODA-FY, Inception V3, and YOLO, which indicate that our proposed RODA-FY outperforms the other comparison models in recognition accuracy.

    With the restart-up of Browns Ferry NPP on May 22, 2007, the US nuclear park comprises now 104 reactors in operation: 35 BWR-type and 69 PWR-type. NPPs are present in only 31 states and mainly in the eastern half of the country. Nuclear energy represents 20% of the US energy mix (coal: 50%, gas: 19%, hydro-power: 6%, petroleum: 3% and other renewable energies: 2%). The highest average availability rate in power generation is reached by nuclear energy (89.9%). The nuclear power generation reached 787.2 TWh in 2006, i.e. the second best result after the 2004 record (788.5 TWh). This document presents also some nuclear safety and radioprotection indicators (number of unplanned outages, failures, injury frequency rate), the programme of licenses extension, the permissions for power increase, the demands for design certification, for early site permit, and for combined construction permit and operating license. The regulation may be different from one state to the other and sometimes not favorable to a re-launch of nuclear energy. The situation of each state in this domain is presented in appendix. (J.S.)

  5. On the Role of Situational Stressors in the Disruption of Global Neural Network Stability during Problem Solving.

    2017-12-01

    When individuals are placed in stressful situations, they are likely to exhibit deficits in cognitive capacity over and above situational demands. Despite this, individuals may still persevere and ultimately succeed in these situations. Little is known, however, about neural network properties that instantiate success or failure in both neutral and stressful situations, particularly with respect to regions integral for problem-solving processes that are necessary for optimal performance on more complex tasks. In this study, we outline how hidden Markov modeling based on multivoxel pattern analysis can be used to quantify unique brain states underlying complex network interactions that yield either successful or unsuccessful problem solving in more neutral or stressful situations. We provide evidence that brain network stability and states underlying synchronous interactions in regions integral for problem-solving processes are key predictors of whether individuals succeed or fail in stressful situations. Findings also suggested that individuals utilize discriminate neural patterns in successfully solving problems in stressful or neutral situations. Findings overall highlight how hidden Markov modeling can provide myriad possibilities for quantifying and better understanding the role of global network interactions in the problem-solving process and how the said interactions predict success or failure in different contexts.

    The integration of photovoltaic (PV) systems in buildings shows several advantages compared to conventional PV power plants. The main objectives of the present study are the quantitative evaluation of the benefits of building-integrated PV systems over their entire life-cycle and the identification of best solutions to maximise their energy efficiency and CO 2 mitigation potential. In order to achieve these objectives, a simplified life-cycle analysis (LCA) has been carried out. Firstly, a number of existing applications have been studied. Secondly, a parametric analysis of possible improvements in the balance-of-system (BOS) has been developed. Finally, the two steps have been combined with the analysis of crystalline silicon technologies. Results are reported in terms of several indicators: energy pay-back time, CO 2 yield and specific CO 2 emissions. The Indicators show that the integration of PV systems in buildings clearly increases the environmental benefits of present PV technology. These benefits will further increase with future PV technologies. Future optimised PV roof-integrated systems are expected to have an energy pay-back time of around 1-5 years (1 year with heat recovery) and to save during their lifetime more than 20 times the amount of CO 2 emitted during their manufacturing (34 times with heat recovery).

    This invited keynote paper is the most recent among similar reviews published by the author, update to year 2011. In a format similar to that in past reviews, recent estimates and forecasts of the conventional fossil fuel resources and their reserve/production ratio, nuclear power, and renewable energy potential, and energy uses are surveyed. A brief discussion of the status, sustainability (economic, environmental and social impact), and prospects of fossil, nuclear and renewable energy use, and of power generation is presented. Beyond the general review, the paper focuses this year on some of the many important areas that deserve more attention: (1) the recently emerging game-changing developments of postponement of “peak oil”, nuclear power future following the disaster in Japan, and effects of the recent global economy downturn of global sustainability, (2) the potential and impacts of electric cars (3) the often neglected energy status and promising potential of Africa. Some ways to resolve the problem of the availability, cost, and sustainability of energy resources alongside the rapidly rising demand are discussed. The author’s view of the promising energy R and D areas, their potential, foreseen improvements and their time scale, and last year’s trends in government funding are presented.

    The currently dominating research paradigm in evidence-based medicine is expounded and discussed regarding the problems deduced from so-called empirically supported treatments (EST) in psychology and psychotherapy. Prevalent political and economic as well as ideological backgrounds influence the present dominance of the medical model in psychotherapy by implementing the randomized-controlled research design as the standard in the field. It has been demonstrated that randomized controlled trials (RCTs) are inadequate in psychotherapy research, not the least because of the high complexity of the psychotherapy and the relatively weak role of the treatment concept in the change process itself. All major meta-analyses show that the Dodo bird verdict is still alive, thereby demonstrating that the medical model in psychotherapy with its RCT paradigm cannot explain the equivalence paradox. The medical model is inappropriate, so that the contextual model is proposed as an alternative. Extensive process-outcome research is suggested as the only viable and reasonable way to identify highly complex interactions between the many factors regularly involved in change processes in psychotherapy.

    Belgonucleaire has been operating the Dessel MOX plant at an industrial scale between 1986 and 2006. During this period, 40 metric tons of plutonium (HM) have been processed into 90 reloads of MOX fuel for commercial light water reactors. The decision to stop the production in 2006 and to decommission the MOX plant was the result of the shrinkage of the MOX fuel market due to political and commercial factors. As a significant part of the decommissioning project of the Dessel MOX plant, about 170 medium-sized glove-boxes and about 1.200 metric tons of structure and equipment outside the glove-boxes are planned for dismantling. The license for the dismantling of the MOX plant was granted by Royal Decree in 2008 and the dismantling started in March 2009. The dismantling works are carried out by an integrated organization under leadership and responsibility of Belgonucleaire; this organization includes 3 main contractors, namely Tecnubel N.V., the THV ('Tijdelijke HandelsVereniging') Belgoprocess / SCK-CEN and Studsvik GmbH and Tractebel Engineering as project manager. In this paper, after having described the main characteristics of the project, the authors review the different organizational and technical options considered for the decommissioning of the glove-boxes; thereafter the main decision criteria (qualification of personnel and of processes, confinement, cutting techniques and radiation protection, safety aspects, alpha-bearing waste management) are analyzed as well. Finally the progress, the feedback and the lessons learned at the end of August 2013 are presented, giving the principal's and contractors point of view. (authors)

    Full Text Available Vehicle group situation is the status and situation of dynamic permutation which is composed of target vehicle and neighboring traffic entities. It is a concept which is frequently involved in the research of traffic flow theory, especially the active vehicle security. Studying vehicle group situation in depth is of great significance for traffic safety. Three-lane condition was taken as an example; the characteristics of target vehicle and its neighboring vehicles were synthetically considered to restructure the vehicle group situation in this paper. The Gamma distribution theory was used to identify the vehicle group situation when target vehicle arrived at the end of the study area. From the perspective of driver-vehicle feature evolution, the reverse reconstruction method of vehicle group situation in the urban road network was proposed. Results of actual driving, virtual driving, and simulation experiments showed that the model established in this paper was reasonable and feasible.

    To learn the conceptions and actions of health professionals on the care network for women in situations of violence. A qualitative, descriptive, exploratory study was conducted between April and July 2015 with the participation of 21 health professionals from four primary health care teams in a city of the central region of the state of Rio Grande do Sul. Data were collected by means of individual semi-structured interviews. Content analysis was used for data systematization. Health professionals recognized the importance of the health care network for coping with the problem of violence against women. However, their conceptions and actions were limited by the discoordination or absence of integration among professionals and services of the care network. The conceptions and actions of health professionals contribute to the discoordination among the services. It is necessary to reflect on the daily practices of care for women in situations of violence.

A coleta de dados ocorreu mediante entrevistas semiestruturadas e individuais. Para sistematização dos dados, empregou-se a análise de conteúdo. Os profissionais de saúde reconheciam a importância da rede de atenção à saúde no enfrentamento da problemática da violência contra as mulheres. Contudo, suas concepções e ações eram limitadas pela desarticulação ou ausência de integração entre os profissionais e serviços da rede de atenção. As concepções e ações dos profissionais de saúde contribuem para a desarticulação entre os serviços. Faz-se necessário refletir acerca das práticas cotidianas de cuidados

  17. Estimation of the Net Present Value of the Investment Project in the Situation of Fuzzy Initial Data

    Directory of Open Access Journals (Sweden)

    Kotsyuba Oleksiy S.

    2017-03-01

    Full Text Available The article investigates the problem of estimating the net present value of the investment project using a methodology based on the theory of fuzzy sets in the situation when the initial data are described by fuzzy estimates. In the general case the fuzzy-multiple estimation of the specified indicator at a discrete-interval representation of the initial parameters is reduced to a set of homogeneous optimization problems. Often, depending on the characteristics of fuzzy estimates of cash flows of the investment project under consideration, the solutions to these problems can be found directly on the basis of relevant analytical expressions, while other problems require using special optimization methods. In the work there made an attempt to develop the analytical component of the fuzzy-multiple modeling of the net present value indicator. First, we examined the general search and optimization approach, which allows providing a predetermined degree of accuracy, as well as the method for approximate determination of the fuzzy estimate of the net present value on the basis of analytical relationships developed by Сhui-Yu Chiu and Chan S. Park. After that, the situation was analyzed, and the corresponding calculation model was proposed, when fuzzy estimates of the cash flows of the investment project can be interpreted from the perspective of the concept of the money-generating operation formulated by O. B. Lozhkin. Among other things, it allowed to develop a general scheme for determining the fuzzy estimate of the net present value, supplementing it with the situation of this concept. As the main direction of the further development of the problems discussed in the publication there determined the formation of a holistic methodology for evaluating the effectiveness of real investments, which would cover different in their nature and structural characteristics types of uncertainty from unified theoretical positions.

    Space weather forecasting is a very important tool for the space situational awareness to the space objects, the space environment and related threats and risks for manned and non-manned spacecrafts. The global network of ground based multi-directional detectors (GMDN) can be considered as one example of an important emerging Space Situational Awareness program around the world, since its requirements needs global technical, scientific and logistic collab-oration between several countries in different continents. ICMEs accompanied by a strong shock often forms a high-energy galactic cosmic rays (GCRs) depleted region behind the shock known as a Forbush decrease. The ICME arrival also causes a systematic variation in the GCR streaming (i.e. the directional anisotropy of intensity). The magnitude of the streaming is small (about 1 % or less), but its variation is relevant. Some particles from this suppressed density region traveling with about the speed of light leak into the upstream region, much faster than the approaching shock, creating the possibility of being observed at the earth, by a global net-work of ground based multi-directional detectors (GMDN), as precursory loss-cone anisotropy. Loss-cones are typically visible 4-8 hours ahead of shock arrival for shocks associated with ma-jor geomagnetic storms. A multi-directional muon detector for detection of GCR was installed in 2001, through an international cooperation between Brazil, Japan and USA, and has been in operation since then at the Southern Space Observatory -SSO/CRS/INPE -MCT, (29.4° S, 53.8° W, 480m a.s.l), Sao Martinho da Serra, RS, in southern Brazil. The detector's capability and sensitivity were upgraded in 2005. The observations conducted by this detector are used for forecasting the arrival of the geomagnetic storm and their interplanetary coronal mass ejec-tion (ICME) drivers in the near-earth geospace. The detector measures high-energy GCRs by detecting secondary muons produced from the

    Full Text Available The paper is focused on comparing the classification ability of the model with self-learning neutral network and methods from cluster analysis. The emphasis is particularly on the comparison of different approaches to a specific application example of the commitment, the classification of then financial situation. The aim is to critically evaluate different approaches at the level of application and deployment options.The verify the classification capability of the different approaches were used financial data from the database „Credit Info“, in particular data describing the financial situation of the two hundred eleven farms of homogeneous and uniform primary field.Input data were from the methods used, modified and evaluated by appropriate methodology. Found the final solution showed that the used approaches do not show significant differences, and they can say that they are equivalent. Based on this finding can formulate the conclusion that the approach of artificial intelligence (self-learning neural network is as effective as a partial methods in the field of cluster analysis. In both cases, these approaches can be an invaluable tool in decision making.When the financial situation is evaluated by the expert, the calculation of liquidity, profitability and other financial indicators are making some simplification. In this respect, neural networks perform better, since these simplifications in them selves are not natively included. They can better assess and somewhat ambiguous cases, including businesses with undefined financial situation, the so-called data in the border region. In this respect, support and representation of the graphical layout of the resulting situation sorted out objects using software implemented neural network model.

  6. Kin networks and poverty among African Americans: past and present.

    Science.gov (United States)

    Miller-Cribbs, Julie E; Farber, Naomi B

    2008-01-01

    Trends in social welfare policy and programs place increasing expectations on families to provide members with various forms of material and socioemotional support. The historic ability of kin networks of many African Americans to provide such support has been compromised by long-term community and family poverty. The potential mismatch between the expectations of social welfare systems for kin support and the actual functional capacities of kin networks places African Americans living in poverty at great risk of chronic poverty and its long-term multiple consequences. This article reviews historical and contemporary research on the structure and function of African American kin networks. On the basis of evidence of functional decline, the authors argue that social workers must re-examine the a priori assumption of viable kin networks as a reliable source of resilience among African Americans living in poverty. Social workers must focus assessment at all levels of practice on a variety of aspects of kin networks to make accurate judgments about not only the availability of resources, but also the perceived costs and benefits of participation in exchange for resources.

    Field missions were sent to the Semipalatinsk regions to investigate the present radioecological situation as a result of the radioactive fallout from nuclear test explosions carried out at the former Soviet Union's Semipalatinsk nuclear test site (SNTS). For this purpose, surface and core soil samples were collected at more than 60 sites, including several settlements such as Dolon, Chagan and Sarzhal, within and outside the SNTS territory. The radioactivities of long-lived radionuclides, {sup 137}Cs, {sup 238}Pu and {sup 239,240}Pu, and the atomic ratio of {sup 240}Pu/{sup 239}Pu were determined in combination with non-destructive g-ray spectrometric method and radiochemical separation followed by a-particle spectrometric and/or ICP-MS methods. The results showed a distinction of {sup 137}Cs and {sup 239,240}Pu inventories in soil depending on a sampling sites. Although {sup 137}Cs was within typical environmental levels except for the area near the first nuclear test site and Balapan, {sup 239,240}Pu was at elevated levels in all areas we visited. This high Pu contamination was recognized to be due to the weapons-grade Pu from the SNTS by the measurement of {sup 240}Pu/{sup 239P}u atomic ratio in soil samples. (author)

    Full Text Available Abstract During the past two decades, the field of human genetics has experienced an information explosion. The completion of the human genome project and the development of high throughput SNP technologies have created a wealth of data; however, the analysis and interpretation of these data have created a research bottleneck. While technology facilitates the measurement of hundreds or thousands of genes, statistical and computational methodologies are lacking for the analysis of these data. New statistical methods and variable selection strategies must be explored for identifying disease susceptibility genes for common, complex diseases. Neural networks (NN are a class of pattern recognition methods that have been successfully implemented for data mining and prediction in a variety of fields. The application of NN for statistical genetics studies is an active area of research. Neural networks have been applied in both linkage and association analysis for the identification of disease susceptibility genes. In the current review, we consider how NN have been used for both linkage and association analyses in genetic epidemiology. We discuss both the successes of these initial NN applications, and the questions that arose during the previous studies. Finally, we introduce evolutionary computing strategies, Genetic Programming Neural Networks (GPNN and Grammatical Evolution Neural Networks (GENN, for using NN in association studies of complex human diseases that address some of the caveats illuminated by previous work.

    In East European countries (Albania, Bulgaria, Czech, Slovakia, Hungary, Poland, Rumania and former Yugoslavia), energy prices were raised as part of the general price reform in the initial stage of the economic reform. Trade regulations on energy products were relaxed, and prices of tradable energy products were made free. Even in countries such as Rumania and Bulgaria where there still remain controls, the governments aim at perfect liberalization. Thus, this paper first considered the energy situation of East European countries where economy and society are now changing. Described were the overall economy situation and energy supply/demand in East European countries. Next, the paper detailed the energy situation in Hungary and Poland. In conclusion, the paper considered energy and international cooperation, and Pan-european Energy Charter which are important future issues in the energy sector of East European countries. 10 refs., 36 figs., 26 tabs.

    Functional connectivity maps of neuronal networks are critical tools to understand how neurons form circuits, how information is encoded and processed by neurons, how memory is shaped, and how these basic processes are altered under pathological conditions. Current light microscopy allows to observe calcium or electrical activity of thousands of neurons simultaneously, yet assessing comprehensive connectivity maps directly from such data remains a non-trivial analytical task. There exist simple statistical methods, such as cross-correlation and Granger causality, but they only detect linear interactions between neurons. Other more involved inference methods inspired by information theory, such as mutual information and transfer entropy, identify more accurately connections between neurons but also require more computational resources. We carried out a comparative study of common connectivity inference methods. The relative accuracy and computational cost of each method was determined via simulated fluorescence traces generated with realistic computational models of interacting neurons in networks of different topologies (clustered or non-clustered) and sizes (10-1000 neurons). To bridge the computational and experimental works, we observed the intracellular calcium activity of live hippocampal neuronal cultures infected with the fluorescent calcium marker GCaMP6f. The spontaneous activity of the networks, consisting of 50-100 neurons per field of view, was recorded from 20 to 50 Hz on a microscope controlled by a homemade software. We implemented all connectivity inference methods in the software, which rapidly loads calcium fluorescence movies, segments the images, extracts the fluorescence traces, and assesses the functional connections (with strengths and directions) between each pair of neurons. We used this software to assess, in real time, the functional connectivity from real calcium imaging data in basal conditions, under plasticity protocols, and epileptic

    2006-01-01

    In this paper, a neural network based operator support system is proposed to reduce operator's errors in abnormal situations in nuclear power plants (NPPs). There are many complicated situations, in which regular and suitable operations should be done by operators accordingly. In order to regulate and validate operators' operations, it is necessary to develop an operator support system which includes computer based procedures with the functions for operation validation. Many computerized procedures systems (CPS) have been recently developed. Focusing on the human machine interface (HMI) design and procedures' computerization, most of CPSs used various methodologies to enhance system's convenience, reliability and accessibility. Other than only showing procedures, the proposed system integrates a simple CPS and an operation validation system (OVS) by using artificial neural network (ANN) for operational permission and quantitative evaluation

    2016-01-01

    The authorization to operate an installation for the fission of nuclear fuel for the commercial production of electricity was withdrawn for the seven oldest NPPs and NPP Kruemmel in Germany on August 6, 2011 after the events at Japanese Nuclear Power Plant (NPP) Fukushima Daiichi in March 2011. In the meantime, all these NPPs applied for decommissioning. One aspect reflected in the applications for these NPPs is the possibility that spent nuclear fuel elements or fuel rods will still be present in the cooling ponds at least during the first stage of decommissioning, i.a. due to limited availability of spent fuel casks. Although considerable decommissioning experiences are available in Germany, the approach 'decommissioning with fuel elements present' has been the exceptional case so far. The paper highlights the efforts undertaken to strengthen the regulatory framework with respect to decommissioning in Germany taking into account this changed approach. The paper presents a short introduction to the legal and regulatory requirements for decommissioning in Germany. Afterwards, the updates to the Decommissioning Guide, which includes proposals for an appropriate procedure for the decommissioning, safe enclosure and dismantling of facilities or parts thereof as defined in item 7 of the German Atomic Energy Act in respect of the application of the technical rules for planning and preparation of decommissioning measures as well as for licensing and supervision, are highlighted. In addition, the amendments to the Guidelines for the Decommissioning of Nuclear Facilities of the Nuclear Waste Management Commission (ESK), which is complementary to the Decommissioning Guide in a technical sense, are reported as well.

    2013-12-01

    The Earth, as viewed from a physicist's perspective, is a dynamical system of great complexity. Functional complex networks are inferred from observational data and model runs or constructed on the basis of theoretical considerations. Representing statistical interdependencies or causal interactions between objects (e.g., Earth system subdomains, processes, or local field variables), functional complex networks are conceptually well-suited for naturally addressing some of the fundamental questions of Earth system analysis concerning, among others, major dynamical patterns, teleconnections, and feedback loops in the planetary machinery, as well as critical elements such as thresholds, bottlenecks, and switches. The first part of this talk concerns complex network theory and network-based time series analysis. Regarding complex network theory, the novel contributions include consistent frameworks for analyzing the topology of (i) general networks of interacting networks and (ii) networks with vertices of heterogeneously distributed weights, as well as (iii) an analytical theory for describing spatial networks. In the realm of time series analysis, (i) recurrence network analysis is put forward as a theoretically founded, nonlinear technique for the study of single, but possibly multivariate time series. (ii) Coupled climate networks are introduced as an exploratory tool of data analysis for quantitatively characterizing the intricate statistical interdependency structure within and between several fields of time series. The second part presents applications for detecting dynamical transitions (tipping points) in time series and studying bottlenecks in the atmosphere's general circulation structure. The analysis of paleoclimate data reveals a possible influence of large-scale shifts in Plio-Pleistocene African climate variability on events in human evolution. This presentation summarizes the contents of the dissertation titled "Functional network macroscopes for

    Neurocysticercosis (NCC), which is caused by accidental ingestion of eggs of the pork tapeworm, Taenia solium, was common in Bali, Indonesia until the early 1990s. However, improved education on hygiene and sanitation, a move to keeping pigs indoors, and improvement of economic and living conditions have substantially reduced the occurrence of NCC in Bali. Since 2011, T. solium tapeworm carriers (T. solium taeniasis) and heavily infected pigs and dogs have exclusively been detected from villages in mountainous regions of northeastern Bali where NCC and ocular cysticercosis (OCC) cases have also been identified. In response to this continued area of high infection, a one-day workshop was convened to discuss how to prevent and control this potentially lethal zoonotic parasitic infection in Bali. This review presents an overview of the current status of T. solium taeniasis and cysticercosis in Indonesia and proposes a strategy for the prevention and control of this zoonosis in Bali.

    A ''baby cyclotron'' has been developed by the Japan Steel Works, Ltd. Its No. 1 model (proton 9.4 MeV) was delivered to the Nakano Hospital of National Sanatorium in March, 1979. It is being used successfully for the production of 11 C, 13 N and 15 O and labeled compounds. The proton or deuteron particles accelerated in the cyclotron collide on target materials. The target box, which is automatically changeable, is directly installed to the accelerating box, thereby taking the safety measures for any leaking radiation. The following matters are described: the production of short-lived radioisotopes (RI yields and treatment); the processes of production in the Nakano Hospital, with No. 1 baby cyclotron, including the photosynthesis of labeled compounds such as 11 C-labeled glucose; the research on the automation in the synthesis of organic labeled compounds like 11 C-palmitic acid.

    Full Text Available In the present edition of Significação – Scientific Journal for Audiovisual Culture and in the others to follow something new is brought: the presence of thematic dossiers which are to be organized by invited scholars. The appointed subject for the very first one of them was Radio and the invited scholar, Eduardo Vicente, professor at the Graduate Course in Audiovisual and at the Postgraduate Program in Audiovisual Media and Processes of the School of Communication and Arts of the University of São Paulo (ECA-USP. Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”. Andrew Dubber (Birmingham City University regarding the challenges posed by a Digital Era argues for a theoretical approach in radio studies which can consider a Media Ecology. The author understands the form and discourse of radio as a negotiation of affordances and

    The advent of social networking sites has facilitated the dissemination of scientific research. This article aims to investigate the presence of Iranian highly cited clinicians in social networking sites. This is a scientometrics study. Essential Science Indicator (ESI) was searched for Iranian highly cited papers in clinical medicine during November-December 2015. Then, the authors of the papers were checked and a list of authors was obtained. In the second phase, the authors' names were searched in the selected social networking sites (ResearchGate [RG], Academia, Mendeley, LinkedIn). The total citations and h-index in Scopus were also gathered. Fifty-five highly cited papers were retrieved. A total of 107 authors participated in writing these papers. RG was the most popular (64.5%) and LinkedIn and Academia were in 2 nd and 3 rd places. None of the authors of highly cited papers were subscribed to Mendeley. A positive direct relationship was observed between visibility at social networking sites with citation and h-index rate. A significant relationship was observed between the RG score, citations, reads indicators in RG, and citation numbers and there was a significant relationship between the number of document indicator in Academia and the citation numbers. It seems putting the papers in social networking sites can influence the citation rate. We recommend all scientists to be present at social networking sites to have better chance of visibility and also citation.

    Full Text Available Abstract Background In 2000, the national cancer plan for England created 34 cancer networks, new organisational structures to coordinate services across populations varying between a half and three million people. We investigated the availability of data sets reflecting measures of structure, process and outcome that could be used to support network management. Methods We investigated the properties of national data sets relating to four common cancers – breast, colorectal, lung and prostate. We reviewed the availability and completeness of these data sets, identified leading items within each set and put them into tables of the 34 cancer networks. We also investigated methods of presentation. Results The Acute Hospitals Portfolio and the Cancer Standards Peer Review recorded structural characteristics at hospital and cancer service level. Process measures included Hospital Episode Statistics, recording admissions, and Hospital Waiting-List data. Patient outcome measures included the National Survey of Patient Satisfaction for cancer, and cancer survival, drawn from cancer registration. Data were drawn together to provide an exemplar indicator set a single network, and methods of graphical presentation were considered. Conclusion While not as yet used together in practice, comparative indicators are available within the National Health Service in England for use in performance assessment by cancer networks.

    In this paper, the background of performance testing of in-service process flow compressors set in user field are introduced, the main technique barriers faced in the field test are summarized, and the factors that result in real efficiencies of most process flow compressors being lower than the guaranteed by manufacturer are analysed. The authors investigated the present operational situation of process flow compressors in China and found that low efficiency operation of flow compressors is because the compressed gas is generally forced to flow back into the inlet pipe for adapting to the process parameters variety. For example, the anti-surge valve is always opened for centrifugal compressor. To improve the operation efficiency of process compressors the energy efficiency monitoring technology was overviewed and some suggestions are proposed in the paper, which is the basis of research on energy efficiency evaluation and/or labelling of process compressors.

    Through social media and camera phones, users enact selective self-presentation as they choose, edit, and post photographs of themselves (such as selfies) to social networking sites for an imagined audience. Photos typically focus on users' physical appearance, which may compound existing sociocultural pressures about body image. We identified users of social networking sites among a nationally representative U.S. sample (N = 1,686) and examined women's and men's photo-related behavior, including posting photos, editing photos, and feelings after engaging in upward and downward social comparison with others' photos on social networking sites. We identified some sex differences: women edited photos more frequently and felt worse after upward social comparison than men. Body image and body comparison tendency mediated these effects.

    The self-presentation of suicidal acts in social media has become a public health concern. This article centers on a Chinese microblogger who posted a wrist-cutting picture that was widely circulated in Chinese social media in 2011. This exploratory study examines written reactions of a group of Chinese microbloggers exposed to the post containing a self-harming message and photo. In addition, we investigate the pattern of information diffusion via a social network. We systematically collected and analyzed 5,971 generated microblogs and the network of information diffusion. We found that a significant portion of written responses (36.6%) could help vulnerable netizens by providing peer-support and calls for help. These responses were reposted and diffused via an online social network with markedly more clusters of users--and at a faster pace-- than a set of randomly generated networks. We conclude that social media can be a double-edged sword: While it may contagiously affect others by spreading suicidal thoughts and acts, it may also play a positive role by assisting people at risk for suicide, providing rescue or support. More research is needed to learn how suicidally vulnerable people interact with online suicide information, and how we can effectively intervene.

    Full Text Available Brain computer interfaces rely on machine learning algorithms to decode the brain's electrical activity into decisions. For example, in rapid serial visual presentation (RSVP tasks, the subject is presented with a continuous stream of images containing rare target images among standard images, while the algorithm has to detect brain activity associated with target images. Here, we continue our previous work, presenting a deep neural network model for the use of single trial EEG classification in RSVP tasks. Deep neural networks have shown state of the art performance in computer vision and speech recognition and thus have great promise for other learning tasks, like classification of EEG samples. In our model, we introduce a novel spatio-temporal regularization for EEG data to reduce overfitting. We show improved classification performance compared to our earlier work on a five categories RSVP experiment. In addition, we compare performance on data from different sessions and validate the model on a public benchmark data set of a P300 speller task. Finally, we discuss the advantages of using neural network models compared to manually designing feature extraction algorithms.

    Psychological research on gender differences in self-presentation has already revealed that women place higher priority on creating a positive self-presentation, while men are less concerned about the image they present in face-to-face (ftf) communication. Nowadays, with the extensive use of new media, self-presentation is no longer so closely tied to ftf situations, but can also take place in the online world. Specifically, social networking sites (SNS), such as Facebook or MySpace, offer various features such as profile pictures, groups, and virtual bulletin boards with which users can create elaborated online representations of themselves. What remains open is whether this virtual self-presentation on SNS is subject to gender differences. Based on studies emphasizing gender-related differences in Internet communication and behavior in general, it can be assumed that men and women have different motives regarding their SNS usage as well. A multimethodological study, combining results of an online survey and a content analysis of 106 user profiles, assessed users' diverse motives for participating in SNS in general, and their use of specific profile elements or self-presentation in particular. In this sample of StudiVZ users, women tend to be more likely to use SNS for comparing themselves with others and for searching for information. Men, on the other hand, are more likely to look at other people's profiles to find friends. Moreover, women tend to use group names for their self-presentation and prefer adding portrait photos to their profiles, while men choose full-body shots.

    Full Text Available This study aimed to explore the present situation of field training for the students of the accounting education in Saudi Universities, so as to raise its level and make the best use of it to gain practical experience and professional skills in accounting and other relevant field skills. To achieve this, a field study was conducted on trainee students of the Accounting Department – Princess Nourah University. To collect data for the study, a questionnaire consisting of two parts was used and distributed to groups of female students who were selected through the stratified random method. The sample represented students who were expected to graduate from the department, and who were registered in the Field Training Program. The sample involved students from different three academic levels, and various training days. The results showed statistically significant differences at (α =0.05 in the type of training for building accounting knowledge and skills of the students in the accounting department. This is attributed to the different training institutions. The results also revealed that writing graduation research simultaneously with the training program, whose allotted time is inadequate, would reduce the chance of gaining the desired experiences of field training. It was also clear that discontinuous training would hinder the students from getting the appropriate training opportunities, and that conducting training during the summer semester seemed sufficient and appropriate. Keywords: Accounting education, Field training.

    In the present situation of health care, financing has become so complicated that the treating doctor has to know not only his profession but also has to consider the different regulations, laws and book of rules. The work of the physician cannot be carried out only through the fact that he is a master of his art, that is healing. All healing practice, diagnostic abilities, intuition, empathy and other things are in vain: if he is not familiar with the basics of financing he can lead his institution to insolvency. This article tries to give a view of a small part of financing, the output volume limit (OVL) from another aspect. According to the basics of economy and general rules of leadership it tries to show up the practical difficulties of the output volume limit. The study enlightens that by defining the output volume limit one has to consider the shutdown point of the hospital and knowing this, the actual output volume limit should be defined in the way that it does not make the proper activity of the hospital completely impossible.

    Knowledge of epidemiologic research topics as well as trends is useful for scientific societies, researchers and funding agencies. In recent years researchers recognized the usefulness of keyword network analysis for visualizing and analyzing scientific research topics. Therefore, we applied keyword network analysis to present an overview of current epidemiologic research topics in Germany. Accepted submissions to the 9th annual congress of the German Society for Epidemiology (DGEpi) in 2014 were used as data source. Submitters had to choose one of 19 subject areas, and were ask to provide a title, structured abstract, names of authors along with their affiliations, and a list of freely selectable keywords. Keywords had been provided for 262 (82 %) submissions, 1030 keywords in total. Overall the most common keywords were: "migration" (18 times), "prevention" (15 times), followed by "children", "cohort study", "physical activity", and "secondary data analysis" (11 times each). Some keywords showed a certain concentration under one specific subject area, e.g. "migration" with 8 of 18 in social epidemiology or "breast cancer" with 4 of 7 in cancer epidemiology. While others like "physical activity" were equally distributed over multiple subject areas (cardiovascular & metabolic diseases, ageing, methods, paediatrics, prevention & health service research). This keyword network analysis demonstrated the high diversity of epidemiologic research topics with a large number of distinct keywords as presented at the annual conference of the DGEpi.

    Iceland is located on the Mid-Atlantic Ridge and thereby offers a rare opportunity to study crustal movements at a divergent plate boundary. Iceland is not only characterized by the divergence of the Eurasian and North American Plates, as several active volcanoes are located on the island. Moderate size earthquakes occur in the transform zones, causing measurable crustal deformation. In 1999 the installation of a permanent network of continuous GPS stations (ISGPS) was initiated in order to observe deformation due to unrest in the Hengill volcanic system and at the Katla volcano. The ISGPS network has been enlarged over the years and consists today of more than 25 CGPS stations. Most of the stations are located along the plate boundary, where most of the active deformation takes place. Uplift due to post-glacial rebound due to the melting of the largest glacier in Europe, Vatnajökull, is also detected by the ISGPS network. This study presents results from analysis of 9 years of data from the ISGPS network, in the global reference frame PDR05, which has been evaluated by the Potsdam-Dresden-Reprocessing group with reprocessed GPS data only. We thus determine subsidence or land uplift in a global frame. The horizontal station velocities clearly show spreading across the plate boundary of about 20 mm/a. Stations in the vicinity of the glacier Vatnajökull indicate uplift in the range of 12 mm/a, while a station in the central part of Iceland shows uplift rates of about 25 mm/a. Tide gauge readings in Reykjavik and current subsidence rates observed with CGPS agree also quite well.

    regionalized cluster-based water isotope prediction model (RCWIP) which uses fuzzy clustering to delineate regions of climatic similarity, and to determine regionalized regression models for each climatic cluster in order to lower prediction uncertainty of isotope values. Here, we present new data and figures on the spatial and temporal evolution of the GNIP network, including station spatial density and coverage analysis. Moreover, we assess outstanding deficits in the spatial coverage of the GNIP network by applying the clustering structure of the RCWIP approach to identify those regions which would benefit most from an improved GNIP sampling. Finally, we present an updated global meteoric water (GMWL) line based on different calculation methods (ordinary least squares method, weighted least squares, or based on weighted means).

    Artificial neural networks (ANNs) are computer programs used to identify complex relations within data. Routine predictions of presence of colorectal pathology based on population statistics have little meaning for individual patient. This results in large number of unnecessary lower gastrointestinal endoscopies (LGEs - colonoscopies and flexible sigmoidoscopies). We aimed to develop a neural network algorithm that can accurately predict presence of significant pathology in patients attending routine outpatient clinics for gastrointestinal symptoms. Ethics approval was obtained and the study was monitored according to International Committee on Harmonisation - Good Clinical Practice (ICH-GCP) standards. Three-hundred patients undergoing LGE prospectively completed a specifically developed questionnaire, which included 40 variables based on clinical symptoms, signs, past- and family history. Complete data sets of 100 patients were used to train the ANN; the remaining data was used for internal validation. The primary output used was positive finding on LGE, including polyps, cancer, diverticular disease or colitis. For external validation, the ANN was applied to data from 50 patients in primary care and also compared with the predictions of four clinicians. Clear correlation between actual data value and ANN predictions were found (r = 0.931; P = 0.0001). The predictive accuracy of ANN was 95% in training group and 90% (95% CI 84-96) in the internal validation set and this was significantly higher than the clinical accuracy (75%). ANN also showed high accuracy in the external validation group (89%). Artificial neural networks offer the possibility of personal prediction of outcome for individual patients presenting in clinics with colorectal symptoms, making it possible to make more appropriate requests for lower gastrointestinal endoscopy. © 2010 The Authors.

    International Nuclear Information System (INIS)

    2016-12-01

    The radiological monitoring of the environment conducted in Polynesia by the Laboratory for the Study and Monitoring of the Environment (LESE lab), consists in regularly collecting and measuring radioactivity in samples from different environmental natures such as air, water, soil but also foodstuff etc, with which the inhabitants may come in contact. This regular monitoring has been carried out since 1962 on seven islands namely Tahiti, Maupiti, Hao, Rangiroa, Iva Oa, Mangareva and Tubuai representative for the five archipelagos. In 2015, the scope of this monitoring was enlarged by including specific a radiological study, consisting in analyzing local foodstuff in the Raivavae atoll, so as to assess the additional man-made radioactivity through the food chain, and soil samples so as to review the residual amount of "1"3"7Cs and Pu isotopes. A few additional measurements, complementary to the ones already made in 2012, were carried out to develop a map of external exposure all over this Austral atoll. For the second year in a row, the LESE lab took part in the Turbo program leaded by DGA and CEA, organizations in charge of radiological monitoring of the military atolls, by analyzing three ocean samples collected on an atoll shore and offshore from the island Moruroa. Almost all samples were processed and evaluated by the LESE laboratory, located on the Tahiti main land, in Vairao; some of the samples were analyzed in one of IRSN's other laboratories based in a suburb from Paris called Orsay in France. A steady decrease in radioactivity level has been observed since the end of the French atmospheric nuclear tests in 1974; the latest observations (2015) show a stable radiological situation, identical throughout the previous years of observation, and measured at a very low level. This residual radioactivity level comes, for the main part, from the "1"3"7Cs. The efficient annual dose, i.e. the additional man-made radioactivity, is below 5 μSv.y"-"1 (5 micro

    In this paper, we describe the architecture of both the PATS and SAP systems and how these two systems interoperate with each other forming a unified capability for deploying intelligence in hostile environments with the objective of providing actionable situational awareness of individuals. The SAP system works in concert with the UICDS information sharing middleware to provide data fusion from multiple sources. UICDS can then publish the sensor data using the OGC's Web Mapping Service, Web Feature Service, and Sensor Observation Service standards. The system described in the paper is able to integrate a spatially distributed sensor system, operating without the benefit of the Web infrastructure, with a remote monitoring and control system that is equipped to take advantage of SWE.

  5. Emergency situations

    International Nuclear Information System (INIS)

    2007-01-01

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

    been recorded are described and their current situation in Brazil is discussed. Since its introduction in 1900-1910, arracacha has been considered a non-demanding crop, presenting some minor disease problems, especially when compared to other vegetable crops. Many of the recorded arracacha diseases in Brazil and other Latin American countries are poorly described, for there is hardly any information about pathogenicity tests, pathogen identity, crop losses and environmental conditions affecting diseases. Worldwide, 27 genera of fungi, three of bacteria, nine of nematodes and five species of viruses have been recorded. Of these, thirteen fungi and all bacteria and nematodes were recorded in Brazil. So far, no virus has been recorded, although virus-like symptoms have been observed. The most important diseases are the root knot, caused by Meloidogyne spp., and the postharvest soft rot caused by Erwinia spp. Commonly occurring diseases are leaf spots caused by Septoria spp., Cercospora spp. and Xanthomonas campestris pv. arracaciae, as well as plant rots caused by Sclerotium rolfsii and Sclerotinia sclerotiorum. Viruses could become of great importance since this crop is vegetatively propagated, and part of the plantlets are now being produced in nurseries by a new technique (pre-rooting and then disseminated to different areas throughout Brazil. As there is no pesticide officially registered for this crop in Brazil, preventive measures of control must be used, such as crop rotation, suitable fertilization and irrigation, and removal and destruction of diseased plants. Arracacha seems to be suitable for organic cropping systems, since few diseases are considered limitant.

  9. A reliability-based approach of fastest routes planning in dynamic traffic network under emergency management situation

    2011-12-01

    Full Text Available In order to establish an available emergency management system, it is important to conduct effective evacuation with reliable and real time optimal route plans. This paper aims at creating a route finding strategy by considering the time dependent factors as well as uncertainties that may be encountered during the emergency management system. To combine dynamic features with the level of reliability in the process of fastest route planning, the speed distribution of typical intercity roads is studied in depth, and the strategy of modifying real time speed to a more reliable value based on speed distribution is proposed. Two algorithms of route planning have been developed to find three optimal routes with the shortest travel time and the reliability of 0.9. In order to validate the new strategy, experimental implementation of the route planning method is conducted based on road speed information acquired by field study. The results show that the proposed strategy might provide more reliable routes in dynamic traffic networks by conservatively treating roads with large speed discretion or with relative extreme real speed value.

  14. Time-dependent deformation of polymer network in polymer-stabilized cholesteric liquid crystals (Conference Presentation)

    Science.gov (United States)

    Lee, Kyung Min; Tondiglia, Vincent P.; Bunning, Timothy J.; White, Timothy J.

    2017-02-01

    Recently, we reported direct current (DC) field controllable electro-optic (EO) responses of negative dielectric anisotropy polymer stabilized cholesteric liquid crystals (PSCLCs). A potential mechanism is: Ions in the liquid crystal mixtures are trapped in/on the polymer network during the fast photopolymerization process, and the movement of ions by the application of the DC field distorts polymer network toward the negative electrode, inducing pitch variation through the cell thickness, i.e., pitch compression on the negative electrode side and pitch expansion on positive electrode side. As the DC voltage is directly applied to a target voltage, charged polymer network is deformed and the reflection band is tuned. Interestingly, the polymer network deforms further (red shift of reflection band) with time when constantly applied DC voltage, illustrating DC field induced time dependent deformation of polymer network (creep-like behavior). This time dependent reflection band changes in PSCLCs are investigated by varying the several factors, such as type and concentration of photoinitiators, liquid crystal monomer content, and curing condition (UV intensity and curing time). In addition, simple linear viscoelastic spring-dashpot models, such as 2-parameter Kelvin and 3-parameter linear models, are used to investigate the time-dependent viscoelastic behaviors of polymer networks in PSCLC.

    Full Text Available Este artigo apresenta a configuração da rede social das mulheres que vivem em situação de violência doméstica num município da região metropolitana de São Paulo. Foram realizadas entrevistas com nove mulheres e oito profissionais e observação em três serviços que compõem a rede de proteção à mulher. Para a análise utilizou-se os pressupostos teóricos de redes sociais. Verificou-se que a violência impingida às mulheres pelos seus parceiros impossibilita a manutenção dos vínculos sociais, colocando-as em situação de isolamento e fragilidade. As instituições e os profissionais podem exercer um papel fundamental para que as mulheres saiam do ciclo de violência, desde que a rede de atenção e os fluxos entre os serviços sejam organizados. O estudo das redes sociais com o enfoque nos vínculos e trocas entre os atores pode contribuir para ampliar o conhecimento sobre a dinâmica relacional na situação de violência.This article presents the configuration of the social network of women living in domestic violence situations in a city in the metropolitan region of São Paulo, Brazil. Interviews were conducted with 9 women and 8 professionals, in addition to observation in three institutions which constitute the network for protection of women. The analysis was underpinned by the theoretical assumptions of social networks. Results show that violence inflicted upon women by their partners make them unable to establish and maintain social bonds, and thus face isolation and ostracism. Professionals and institutions can play a vital role for getting women out of the cycle of violence provided that care networks and services are well organized. Further studies of social networks, focusing on the nature of the links and exchanges among actors may contribute to acquiring knowledge about the relationship dynamics in situation of violence.

  16. Presentation of a stochastic model estimating the wind energy contribution in remote island electrical networks

    2012-01-01

    Highlights: ► This study estimates the maximum wind energy contribution to an isolated micro-grid. ► An integrated computational tool is developed on the basis of stochastic analysis. ► The probability distribution of the wind energy surplus and deficit is estimated. ► The results indicate that a strict penetration limit is imposed to wind energy. -- Abstract: The electrification in remote islands whose electricity distribution network is not connected to the mainland’s grid is mostly based on Autonomous Power Stations (APSs) that are usually characterized by a considerably high electricity production cost, while at the same time the contribution of Renewable Energy Sources (RES) in these regions accounts for less than 10% of the total electricity generation. This actually results from the fact that despite the excellent wind potential of most of these islands, the wind energy contribution is significantly restricted from limits imposed to protect the remote electrical grids from possible instability problems, due to the stochastic wind speed behavior and the variable electricity consumption. On the basis of probability distribution of the load demand of a representative Greek island and the corresponding data related to the available wind potential, the present study estimates the maximum – acceptable by the local grid – wind energy contribution. For that reason, an integrated computational algorithm has been developed from first principles, based on a stochastic analysis. According to the results obtained, it becomes evident that with the current wind turbine technology, wind energy cannot play a key role in coping with the electrification problems encountered in many Greek island regions, excluding however the case of introducing bulk energy storage systems that may provide considerable recovery of the remarkable wind energy rejections expected.

    This study aims to analyze the role of artificial neural networks (ANNs) in cytopathology. More specifically, it aims to highlight the importance of employing ANNs in existing and future applications and in identifying unexplored or poorly explored research topics. A systematic search was conducted in scientific databases for articles related to cytopathology and ANNs with respect to anatomical places of the human body where cytopathology is performed. For each anatomic system/organ, the major outcomes described in the scientific literature are presented and the most important aspects are highlighted. The vast majority of ANN applications are related to cervical cytopathology, specifically for the ANN-based, semiautomated commercial diagnostic system PAPNET. For cervical cytopathology, there is a plethora of studies relevant to the diagnostic accuracy; in addition, there are also efforts evaluating cost-effectiveness and applications on primary, secondary, or hybrid screening. For the rest of the anatomical sites, such as the gastrointestinal system, thyroid gland, urinary tract, and breast, there are significantly less efforts relevant to the application of ANNs. Additionally, there are still anatomical systems for which ANNs have never been applied on their cytological material. Cytopathology is an ideal discipline to apply ANNs. In general, diagnosis is performed by experts via the light microscope. However, this approach introduces subjectivity, because this is not a universal and objective measurement process. This has resulted in the existence of a gray zone between normal and pathological cases. From the analysis of related articles, it is obvious that there is a need to perform more thorough analyses, using extensive number of cases and particularly for the nonexplored organs. Efforts to apply such systems within the laboratory test environment are required for their future uptake.

    Full Text Available Car-to-car communication makes possible offering many services for vehicular environment, mainly to improve the safety. The decentralized kind of these networks requires new protocols to distribute information. The advantages that it offers depend on the penetration rate, that will be enough only after years since the introduction, due to the longevity of the current cars. The V2X communication requires On-Board Units (OBUs in the vehicles, and Road-Side Units (RSUs on the roads. The proposed application uses the peculiarities of the VANETs to advise danger or emergency situations with V2V and V2I message exchange. IEEE 802.11p is standard on which the communication is based, that provides the physical and the MAC layers. The WAVE protocol uses this standard, implementing other protocols defined by the family of standards IEEE P1609 in the upper layers. They define security services, resource management, multichannel operations and the message exchange protocol in WAVE. The performance of the application will be evaluated through many simulations executed in different scenarios, to provide general data independent from them.

    Full Text Available As people increasingly integrate social network sites (SNSs into their daily lives, they also turn to these sites for timely information following crises. To date, few studies have examined the effects of different types of motivation on participatory behaviours within SNSs following crises. In this study, self-determination theory (SDT is applied to examine how individuals are motivated to participate in SNSs following a crisis and how individuals’ participatory behaviours can better assist them understand a crisis. The Malaysia Airlines Flight 370 (MH370 incident is selected as the context for this study, and data is collected following the incident. The results show that different types of motivation result in different participatory behaviours. Controlled motivation is positively related to browsing content, commenting and sharing content. Conversely, autonomous motivation is positively associated with browsing and sharing content. Besides, browsing content and commenting are positively related to people’s situational self-awareness. The theoretical and practical implications of this study are discussed.

    Cotugno described the clinical entity of sciatica in 1764. However, the association between sciatica and compression of lumbar nerve roots was not realized until the 1920s. Back surgery for herniated nucleus pulposus then became fashionable, and plain radiography and myelography enabled preoperative mapping. Recently other imaging techniques have emerged, such as computerized tomography and magnetic resonance imaging. This has increased the knowledge of the etiology of lumbar root compressions, and invasive therapies for sciatica have become more diversified. It is easy to lose perspective among the available imaging procedures and therapeutic techniques. The aim of this paper is to present the current status from a historical point of view, with special emphasis on the most common imaging methods for the investigation of lumbosacral radiculopathies. 48 refs., 4 figs.

    In present research, in order to clarify the actual condition of contamination, the radioactive concentration of the soil and the plant in Koriyama city was measured. It turned out that the radioactive concentration of soil or plants were heavily polluted by caesium-134 and 137, and iodine-131 was already disappeared by its lifetime. Especially, cesium-134 + 137 was ranged 3400 Bq/kg at the surface of soil in garden, however, it was remarkably decreased in the deeper point at 10 cm and ranged 23 Bq/kg, and we cannot detect the cesium at 15 cm. It is necessary for people in Fukushima to decontaminate for reducing radioactivity level. And it turned out that the evergreen plants have been polluted at high radioactive concentration and decontamination by cutting down the plant was decreased by 14% average. Most of radioactive material is removed by removing soils. (author)

    The accident at the Fukushima Dai-ichi Nuclear Power Plant (NPP) in March 2011 affected not only the terrestrial environment of Fukushima prefecture and the surrounding area, but also the marine area facing the NPP. Our present study is focused on the concentrations of radionuclides in agricultural products of Fukushima and sea-foods collected off Fukushima after the accident. The regulation value for radiocesium in vegetables, meat and fish was revised from 500 Bq/kg-wet to 100 Bq/kg-wet on 1 April 2012. The overall activity of radiocesium in these products was found to be within the limit of tolerance in respect to Japanese and also international regulations, but there is still radiocesium found at activities greater than this level in edible wild plants, wild mushrooms and game such as boar meat. Although the activities of radionuclides exceeding the regulatory limits were not detected in marine products collected off Fukushima after April 2015, the commercial marine fishery has not received approval in the affected areas except for certain species. We learned from the Fukushima accident that long-term kinetic studies of radionuclides in terrestrial and marine environments is extremely important for prevention of internal contamination, since contamination with radionuclides occurs via the food chain in the environment. © World Health Organisation 2016.

    Full Text Available Cet article passe en revue les différents systèmes catalytiques de post-traitement utilisés actuellement sur la plupart des automobiles pour limiter leurs rejets de polluants. Les systèmes sont différenciés par leur mode de fonctionnement, le type de moteur à dépolluer (deux-temps, quatre-temps, diesel ou essence ou par leur mode de réalisation. Les nouvelles orientations, prévues pour respecter les futures réglementations antipollution, sont également décrites. On montre que certains véhicules prototypes, équipés de moteurs à combustion interne, sont capables d'avoir des émissions très proches de zéro tout comme les véhicules électriques. A review is made of the various types of exhaust gas aftertreatment systems presently used on most vehicles to reduce pollutant emissions. The systems are differentiated by their mode of action, according to the engine type to be depolluted (two-stroke, four-stroke, diesel or spark-ignition, and by their type of make-up. The major developments foreseen in the future, in view of compliance with the new legislations, are described. It is shown that some prototype vehicles with internal combustion engines are able to emit pollutant quantities really close to zero, such as electric cars.

    Full Text Available Metabolitos secundários produzidos e libertados por plantas, bactérias e fungos estão envolvidos numa variedade de processos ecológicos, nomeadamente como semioquímicos e alelopatinos. Adicionalmente, e para além das suas possíveis funções ecológicas, muitos dos metabolitos secundários são fitotóxicos, constituindo uma fonte relativamente inexplorada de novos herbicidas. Solanum nigrum (erva-moira é uma infestante importante e muito bem sucedida num grande número de culturas, nomeadamente hortícolas e será usada como exemplo principal das utilizações actuais de aleloquímicos vegetais bem como das perspectivas de utilização deste tipo de compostos como bioherbicidas. Nesse âmbito revêem-se as principais estratégias de pesquisa de bioherbicidas e apresenta-se o estado da arte dos modos de acção de aleloquímicos já comercializados como herbicidas (Bialaphos e PPT, patenteados (AAL-toxina e em investigação, quer produzidos por plantas superiores (sorgoleona e derivados do cineol quer de origem bacteriana (hidantocidina e fúngica (fumonisinas, coletotriquina.Secondary metabolites produced and released by plants, bacteria, and fungi are involved in a number of ecological processes, namely as semiochemicals and allelopathins. In addition, and beside their possible ecological roles, a greater number of secondary metabolites are phytotoxic and represent a relatively unexplored source of new herbicides. Solanum nigrum (black nightshade is an important and successful weed in many crops, namely in horticulture, and will be used as a major example of actual and prospective uses of phytoallelochemicals as bioherbicides. Therefore, the main strategies for bioherbicides search are reviewed and the state of art of the modes of action of allelochemicals is presented, including those already in use as herbicides (Bialaphos and PPT, patented (AAL-toxin, and under investigation, whether produced by plants (sorgoleone and cineol

    SERS investigations and electrical recording of neuronal networks with three-dimensional plasmonic nanoantennas Michele Dipalo, Valeria Caprettini, Anbrea Barbaglia, Laura Lovato, Francesco De Angelis e-mail: francesco.deangelis@iit.it Istituto Italiano di Tecnologia, Via Morego 30, 16163, Genova Biological systems are analysed mainly by optical, chemical or electrical methods. Normally each of these techniques provides only partial information about the environment, while combined investigations could reveal new phenomena occurring in complex systems such as in-vitro neuronal networks. Aiming at the merging of optical and electrical investigations of biological samples, we introduced three-dimensional plasmonic nanoantennas on CMOS-based electrical sensors [1]. The overall device is then capable of enhanced Raman Analysis of cultured cells combined with electrical recording of neuronal activity. The Raman measurements show a much higher sensitivity when performed on the tip of the nanoantenna in respect to the flat substrate [2]; this effect is a combination of the high plasmonic field enhancement and of the tight adhesion of cells on the nanoantenna tip. Furthermore, when plasmonic opto-poration is exploited [3] the 3D nanoelectrodes are able to penetrate through the cell membrane thus accessing the intracellular environment. Our latest results (unpublished) show that the technique is completely non-invasive and solves many problems related to state-of-the-art intracellular recording approaches on large neuronal networks.

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

    1997-01-01

    Heating entrepreneurs are farmers, who usually have a wood-lot of their own, or entrepreneurs, who have undertaken to look after the supply of fuel to real estates and their heating. The TTS- Institute conducted an analysis of the scope of heating enterpreneurship in connection with the project belonging to the national Bioenergy Research Programme. According to the responses obtained in a mail questionnaire study conducted in autumns 1996, and other data obtained on the subject, there were 36 active heating entrepreneur sites in Finland in December 1996. Heating enterpreneurship, usually involving the supply of chipped wood, has become more common during the past few years. In 1994, it was started at ten places, in 1995 at eight places, and in 1996 at twelve places. The majority, nearly three quarters, of the heating enterpreneurship sites at the end of 1996 were school buildings and one fifth were district heating plants. The solid fuel boiler capacity of all the plants in the study was 11.5 MW. The district heating plants were 0.3-2.5 MW in capacity, the school buildings were in the 60-500 kW range, old peoples'' homes had capacities of 300-370 kW. Except for one school building using sod peat as primary fuel, wood chips was the primary fuel used by institutional buildings. The enterprise form was that of an entrepreneur or a pool formed by entrepreneurs in the case of 27 entrepreneurs, a company in the case of 6, and a co-operative society in the case of three. There were 56 heating-enterpreneurship sites at the implementation or planning stage. Four fifths of them involved heat generation capacity of less than 500 kW and one fifth a capacity of 0.5-2.0 Mw Tyoetehoseuran Metsaetiedote. 13 refs., 3 figs

    After having had defined the concept of research and stages of scientific method in the health field, there has been an attempt to deal with the characteristics of radiological research in the last years, as well as current and future guidelines of such. Among those items considered are the concept of teams which would be interdisciplinary and multi-centered (molecular imaging, imaging-guided therapy, early detection of illness using imaging techniques), as well as the need for certain changes in mentality. As such, there would appear a new generation of scientists (with training in molecular biology, bioengineering, physiopathology and pharmacology) who would bring to fruition an integral use of computers to complement research and imaging techniques. Finally, the concept of evidence-based radiology is analyzed, along with its principles and associated repercussions in health care and research. (Author) 15 refs

    2013-01-01

    The purpose of this study is to provide an understanding of how tourists' self-presentation is managed on social networking sites (SNS). Specifically, the study investigated the effects of SNS use on social support and tourism experience and the moderating role of the different tourists' self......-presentation strategies. The results emphasize the importance of SNS use for tourists to seek support from their social network while traveling. The study clarifies the importance of SNS use for tourism experience, in that the more tourists are engaged in social activities through SNS while traveling, the more social...... support they will get, which will contribute positively to their tourism experience. Also, it is argued that social support does not always directly result from the intense SNS use, but rather moderated by tourists' self-presentation strategies....

  9. The Hsc/Hsp70 co-chaperone network controls antigen aggregation and presentation during maturation of professional antigen presenting cells.

    Directory of Open Access Journals (Sweden)

    Nadja Kettern

    Full Text Available The maturation of mouse macrophages and dendritic cells involves the transient deposition of ubiquitylated proteins in the form of dendritic cell aggresome-like induced structures (DALIS. Transient DALIS formation was used here as a paradigm to study how mammalian cells influence the formation and disassembly of protein aggregates through alterations of their proteostasis machinery. Co-chaperones that modulate the interplay of Hsc70 and Hsp70 with the ubiquitin-proteasome system (UPS and the autophagosome-lysosome pathway emerged as key regulators of this process. The chaperone-associated ubiquitin ligase CHIP and the ubiquitin-domain protein BAG-1 are essential for DALIS formation in mouse macrophages and bone-marrow derived dendritic cells (BMDCs. CHIP also cooperates with BAG-3 and the autophagic ubiquitin adaptor p62 in the clearance of DALIS through chaperone-assisted selective autophagy (CASA. On the other hand, the co-chaperone HspBP1 inhibits the activity of CHIP and thereby attenuates antigen sequestration. Through a modulation of DALIS formation CHIP, BAG-1 and HspBP1 alter MHC class I mediated antigen presentation in mouse BMDCs. Our data show that the Hsc/Hsp70 co-chaperone network controls transient protein aggregation during maturation of professional antigen presenting cells and in this way regulates the immune response. Similar mechanisms may modulate the formation of aggresomes and aggresome-like induced structures (ALIS in other mammalian cell types.

    It is common to associate situated activity with concrete, craftlike or manual activity here and now and to reserve theoretical and abstract thinking for activities like theoretical experimentation and systematic planning. Much work has gone into demonstrating that these activities are concrete...... and situated, too. In this presentation it will be argued that the investigation of systematic planning as conflictual cooperation will help us see that situated activity is not only based on the present conditions, but also relates them to events spread out in time and space, thereby opening up for another...... understanding of theoretical thinking. Some material from the empirical research project developed with Klaus Nielsen on the design and engineering of a house will be presented. On this basis a conception of planning will be unfolded. It will be understood differently from the way it is understood...

    The prediction of cyber-threats situation can effectively reflect the macroscopic security situation of power information network in the future time. To realize the accurate prediction of cyber-threats situation, an AdaBoosting algorithm based cyber-threats situation prediction method for information network is proposed. In the proposed method, the values of cyber-threats situation are used to describe the macroscopic security situation of power information network, and the prediction of macroscopic security situation is abstracted to a regression problem, and then the regression problem is solved by AdaBoosting algorithm. Firstly, using the sliding time window a time series sample set is constructed by cyber-threats situation values;then the sample set is input into AdaBoosting algorithm to be trained to obtain a regression analysis model;finally the prediction of cyber-threats situation is completed by the regression analysis model. Finally, the effectiveness of the proposed method is verified by results of replication experiments based on field data.%威胁态势预测可以有效反映电力信息网络在未来时刻的宏观安全状况。为实现威胁态势的精确预测,提出一种基于AdaBoosting方法的网络威胁态势预测方法。该方法采用威胁态势值描述电力信息网络的宏观安全态势,并将威胁态势值的预测抽象为回归问题,进而利用AdaBoosting方法求解。该方法先利用滑动时间窗口将威胁态势值构造成时间序列样本集,再将样本集输入到AdaBoosting方法中训练,以得到回归分析模型,并利用该模型完成威胁态势预测。最后基于现场数据的验证性实验证明了所提方法的有效性。

  15. Neural network retrievals of Karenia brevis harmful algal blooms in the West Florida Shelf (Conference Presentation)

    Ahmed, Samir; El-Habashi, Ahmed

    2016-10-01

    Effective detection and tracking of Karenia brevis Harmful Algal Blooms (KB HAB) that frequently plague the coasts and beaches of the West Florida Shelf (WFS) is important because of their negative impacts on ecology. They pose threats to fisheries, human health, and directly affect tourism and local economies. Detection and tracking capabilities are needed for use with the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite, so that HABs monitoring capabilities, which previously relied on imagery from the Moderate Resolution Imaging Spectroradiometer Aqua, can be extended to VIIRS. Unfortunately, VIIRS, unlike its predecessor MODIS-A, does not have a 678 nm channel to detect chlorophyll fluorescence, which is used in the normalized fluorescence height (nFLH) algorithm, or in the Red Band Difference (RBD) algorithm. Both these techniques have demonstrated that the remote sensing reflectance signal from the MODIS-A fluorescence band (Rrs 678 nm) helps in effectively detecting and tracking KB HABs in the WFS. To overcome the lack of a fluorescence channel on VIIRS, the approach described here, bypasses the need for measurements at 678nm, and permits extension of KB HABs satellite monitoring to VIIRS. The essence of the approach is the application of a standard multiband neural network (NN) inversion algorithm, previously developed and reported by us, that takes VIIRS Rrs measurements at the 486, 551 and 671nm bands as inputs, and produces as output the related Inherent Optical Properties (IOPs), namely: absorption coefficients of phytoplankton (aph443) dissolved organic matter (ag) and non-algal particulates (adm) as well as the particulate backscatter coefficient, (bbp) all at 443nm. We next need to relate aph443 in the VIIRS NN retrieved image to equivalent KB HABs concentrations. To do this, we apply additional constraints, defined by (i) low backscatter manifested as a maximum Rrs551 value and (ii) a minimum [Chla] threshold (and hence an equivalent

    Demand in many industrial buying situations, e.g. project purchases or procurement related to virtual organizations, is discontinuous. In situations of discontinuity, networks are often more of an ad hos informational and social nature, as strong activity and resource links are not present....... Furthermore the governance structure of markets characterized by discontinuous business activities is either that of the "socially constructed market" (Skaates, 2000) or that of the (socially constructed) network (Håkansson and Johanson, 1993). Additionally relationships and actor bonds vary substantially...

    Full Text Available Men are presented with higher facial prominence than women in the media, a phenomenon that is called face-ism. In naturalistic settings, face-ism effects could be driven by gender biases of photographers and/or by gender differences in self-presentation. The present research is the first to investigate whether women and men themselves create this different facial prominence. In a controlled laboratory study, 61 participants prepared a picture of themselves from a half-body photograph, allegedly to be uploaded to their profile for an online professional network. As expected, men cropped their photos with higher facial prominence than women did. However, women and men did not differ in the self-presentational motivations, goals, strategies, and personality variables under investigation, so that the observed face-ism effect could not be explained with these variables. Generally, the higher participants' physical appearance self-esteem, the higher was their self-created facial prominence.

    A questionnaire investigation about the present situation, current problems and countermeasure to be discussed with by material technology groups in the eight chemical companies was carried out. It has become clear from the analysis of answers obtained that the roll of material group has been changing under the diminishing construction of new plant and the increased needs of stable and sustainable plant operation. The present major subjects of material groups, which are pointed out in the answers, are such new technological problems as the plant life estimation, the dissemination and handing down of material technology and the upbringing of technology successors. The countermeasures to meet those requirements made clear are such technology developments as a new monitoring system, preparation of database on material technology and closer cooperation with relatied associations. It is hoped for that the findings of this study would lead to further and more detailed indentification of common problems to be solved and development of practical countermeasures therefor.

    To assess psychosocial characteristics, symptoms and reasons for seeking integrative medicine (IM) care in cancer patients presenting to IM clinical practices. A survey of 3940 patients was conducted at 8 IM sites. Patient reported outcome measures were collected and clinicians provided health status data. This analysis compares 353 participants self-identified as cancer patients with the larger noncancer cohort. Mean age of the cancer cohort was 55.0 years. Participants were predominantly white (85.9%), female (76.4%), and well educated (80.5% completed college). For 15.2% of cancer patients, depression scores were consistent with depressive symptoms, and average scores for perceived stress were higher than normal, but neither were significantly different from noncancer patients. The most prevalent comorbid symptoms were chronic pain (39.8%), fatigue (33.5%), and insomnia (23.3%). In the cancer cohort, perceived stress was significantly associated with depression, fatigue, insomnia, pain, and QOL. Cancer patients who chose an IM clinical practice "seeking healthcare settings that address spirituality as an aspect of care" had significantly higher levels of perceived stress, depression, and pain than those not selecting this reason. Demographic characteristics, depression scores, perceived stress scores, and reasons for seeking integrative cancer care were not significantly different between cancer patients and noncancer patients. Perceived stress may be an important indicator of QOL. The association of perceived stress, depression and pain with seeking spirituality suggests that providing IM interventions, such as effective stress management techniques and pastoral or spiritual counseling, may be helpful to patients living with cancer. © The Author(s) 2014.

    Since 1987, petrochemical industry has jumped into the era of properity and as a whole, been supported by increasing demands. Although it is said that the 21st Century is the age of chemistry, but for petrochemistry the age of 1990 {prime} s is the age of international competition for the survival towards the 21st Century. The scale of individual enterprise of the Japanese chemical industry including petrochemical enterprises still remains small when compared with that of the individual world-wide chemical enterprises of the U.S.A., Germany and the U.K., etc., besides these world-wide enterprises have established their production bases and research facilities in Japan. In addition, there is somewhat uncertainty in the foundation which is supporting the present prosperity. This article scans the present situation of petrochemistry in its preface, explains the present state and trends of individual industry in the chapters covering the environment around the Japanese petrochemical industry, the report (summary) of the Long Term Credit Bank Institute of Management, trends of advance of oil industry into petrochemical business, production capacity of ethylene and new as well as additional plant construction plans. In this industry, is observed the constitution of Japan which is unable to form internationally competitive power irrespective of her recognition of its necessity because of their giving priority to the balance of their business world. 1 tab.

    Patankar, Pallav; Ekstrand, Maria L

    2016-01-01

    Background The affordability of smartphones and improved mobile networks globally has increased the popularity of geosocial networking (GSN) apps (eg, Grindr, Scruff, Planetromeo) as a method for men who have sex with men (MSM) to seek causal sex partners and engage with the queer community. As mobile penetration continues to grow in India, it is important to understand how self-presentation on GSN app is relevant because it offers insight into a population that has not been largely studied. There is very little information about how Indian MSM discuss their sexual preferences and condom preferences and disclose their human immunodeficiency virus (HIV) status with potential sex partners on Web-based platforms. Objective The objective of this study was to describe how self-presentation by Indian MSM on GSN apps contributes to sexual preferences, HIV or sexually transmitted infection (STI) disclosure, and if the presentation differs due to proximity to the Greater Mumbai or Thane region. Methods Between September 2013 and May 2014, participants were recruited through banner advertisements on gay websites, social media advertisements and posts, and distribution of print materials at outreach events hosted by lesbian, gay, bisexual, transgender (LGBT) and HIV service organizations in Maharashtra, India. Eligible participants self-identified as being MSM or hijra (transgender) women, living in Maharashtra, aged above 18 years, having regular Internet access, and having at least one male sex partner in the previous 90 days. Results Indian MSM living inside and outside the Greater Mumbai or Thane region reported an average of 6.7 (SD 11.8) male sex partners in the last 3 months; on average HIV status of the sex partners was disclosed to 2.9 (SD 8.9). The most commonly used websites and GSN apps by MSM living inside Greater Mumbai or Thane region were Planetromeo, Grindr, and Gaydar. Results demonstrated that MSM used smartphones to access GSN apps and stated a preference

    For the purpose of studying the energy supply/demand trend and the environmental problem relating mainly to coal in the APEC region, the paper surveyed the situation from the past to the present and outlooked the beginning of the 21st century. GDP in the whole APEC region increased at an annual rate of 3.4% from 1971 to 1991 and made a rapid growth of an annual rate over 7% especially in the non-OECD region. The supply/demand balance of coal, etc. in the non-OECD region is expected to be tight, and the energy price also to be higher. This will be a major factor causing hindrance to the economic growth of resource-importing countries. It is necessary to prepare the energy infrastructure. With the increasing coal utilization, it is feared that pollutants such as SOx, NOx and CO2 will increase, and it is necessary to introduce energy utilization technology/facilities which are high-efficient and environment-friendly and to expedite introduction of non-fossil energy. The APEC region, where the worldwide growth is expected, is a priming for the world development, and a policy which is well balanced in economic growth, stabilized energy supply, and environmental protection is needed for the region to achieve its sustainable growth. 50 figs., 24 tabs.

    Networking technologies are exponentially increasing to meet worldwide communication requirements. The rapid growth of network technologies and perversity of communications pose serious security issues. In this paper, we aim to developing an integrated network defense system with situation awareness capabilities to present the useful information for human analysts. In particular, we implement a prototypical system that includes both the distributed passive and active network sensors and traffic visualization features, such as 1D, 2D and 3D based network traffic displays. To effectively detect attacks, we also implement algorithms to transform real-world data of IP addresses into images and study the pattern of attacks and use both the discrete wavelet transform (DWT) based scheme and the statistical based scheme to detect attacks. Through an extensive simulation study, our data validate the effectiveness of our implemented defense system.

    2017-02-01

    To construct an artificial neural network (ANN) model that can predict the presence of acute CT findings with both high sensitivity and high specificity when applied to the population of patients≥age 65years who have incurred minor head injury after a fall. An ANN was created in the Python programming language using a population of 514 patients ≥ age 65 years presenting to the ED with minor head injury after a fall. The patient dataset was divided into three parts: 60% for "training", 20% for "cross validation", and 20% for "testing". Sensitivity, specificity, positive and negative predictive values, and accuracy were determined by comparing the model's predictions to the actual correct answers for each patient. On the "cross validation" data, the model attained a sensitivity ("recall") of 100.00%, specificity of 78.95%, PPV ("precision") of 78.95%, NPV of 100.00%, and accuracy of 88.24% in detecting the presence of positive head CTs. On the "test" data, the model attained a sensitivity of 97.78%, specificity of 89.47%, PPV of 88.00%, NPV of 98.08%, and accuracy of 93.14% in detecting the presence of positive head CTs. ANNs show great potential for predicting CT findings in the population of patients ≥ 65 years of age presenting with minor head injury after a fall. As a good first step, the ANN showed comparable sensitivity, predictive values, and accuracy, with a much higher specificity than the existing decision rules in clinical usage for predicting head CTs with acute intracranial findings.

  15. Quantitative Efficiency Evaluation Method for Transportation Networks

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available An effective evaluation of transportation network efficiency/performance is essential to the establishment of sustainable development in any transportation system. Based on a redefinition of transportation network efficiency, a quantitative efficiency evaluation method for transportation network is proposed, which could reflect the effects of network structure, traffic demands, travel choice, and travel costs on network efficiency. Furthermore, the efficiency-oriented importance measure for network components is presented, which can be used to help engineers identify the critical nodes and links in the network. The numerical examples show that, compared with existing efficiency evaluation methods, the network efficiency value calculated by the method proposed in this paper can portray the real operation situation of the transportation network as well as the effects of main factors on network efficiency. We also find that the network efficiency and the importance values of the network components both are functions of demands and network structure in the transportation network.

  18. Multi-perspective workflow modeling for online surgical situation models.

    Franke, Stefan; Meixensberger, Jürgen; Neumuth, Thomas

    2015-04-01

    Surgical workflow management is expected to enable situation-aware adaptation and intelligent systems behavior in an integrated operating room (OR). The overall aim is to unburden the surgeon and OR staff from both manual maintenance and information seeking tasks. A major step toward intelligent systems behavior is a stable classification of the surgical situation from multiple perspectives based on performed low-level tasks. The present work proposes a method for the classification of surgical situations based on multi-perspective workflow modeling. A model network that interconnects different types of surgical process models is described. Various aspects of a surgical situation description were considered: low-level tasks, high-level tasks, patient status, and the use of medical devices. A study with sixty neurosurgical interventions was conducted to evaluate the performance of our approach and its robustness against incomplete workflow recognition input. A correct classification rate of over 90% was measured for high-level tasks and patient status. The device usage models for navigation and neurophysiology classified over 95% of the situations correctly, whereas the ultrasound usage was more difficult to predict. Overall, the classification rate decreased with an increasing level of input distortion. Autonomous adaptation of medical devices and intelligent systems behavior do not currently depend solely on low-level tasks. Instead, they require a more general type of understanding of the surgical condition. The integration of various surgical process models in a network provided a comprehensive representation of the interventions and allowed for the generation of extensive situation descriptions. Multi-perspective surgical workflow modeling and online situation models will be a significant pre-requisite for reliable and intelligent systems behavior. Hence, they will contribute to a cooperative OR environment. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-01-01

    To assess general public exposure to electromagnetic fields from Long Term Evolution (LTE) base stations, measurements at 10 sites in Thessaloniki, Greece were performed. Results are compared with other mobile cellular networks currently in use. All exposure values satisfy the guidelines for general public exposure of the International Commission on Non-Ionizing Radiation Protection (ICNIRP), as well as the reference levels by the Greek legislation at all sites. LTE electric field measurements were recorded up to 0.645 V/m. By applying the ICNIRP guidelines, the exposure ratio for all LTE signals is between 2.9 x 10"-"5 and 2.8 x 10"-"2. From the measurements results it is concluded that the average and maximum power density contribution of LTE down-link signals to the overall cellular networks signals are 7.8% and 36.7%, respectively.

    2011-01-01

    Full Text Available Abstract Background Hybridization or divergence between sympatric sister species provides a natural laboratory to study speciation processes. The shared polymorphism in sister species may either be ancestral or derive from hybridization, and the accuracy of analytic methods used thus far to derive convincing evidence for the occurrence of present day hybridization is largely debated. Results Here we propose the application of network analysis to test for the occurrence of present day hybridization between the two species of brown algae Fucus spiralis and F. vesiculosus. Individual-centered networks were analyzed on the basis of microsatellite genotypes from North Africa to the Pacific American coast, through the North Atlantic. Two genetic distances integrating different time steps were used, the Rozenfeld (RD; based on alleles divergence and the Shared Allele (SAD; based on alleles identity distances. A diagnostic level of genotype divergence and clustering of individuals from each species was obtained through RD while screening for exchanges through putative hybridization was facilitated using SAD. Intermediate individuals linking both clusters on the RD network were those sampled at the limits of the sympatric zone in Northwest Iberia. Conclusion These results suggesting rare hybridization were confirmed by simulation of hybrids and F2 with directed backcrosses. Comparison with the Bayesian method STRUCTURE confirmed the usefulness of both approaches and emphasized the reliability of network analysis to unravel and study hybridization

    The microseismic network of Ferrara was established, in the beginning of 1990 and started its monitoring activity few months before the start of reservoir exploitation, for residential and industrial heating purposes, of the Casaglia geothermal site characterised by fluids of 100 °C: February 1990. The purpose was to monitor the natural seismicity so as to be able to discriminate it from possible induced ones due to exploitation activities which consists of a closed loop system composed of three boreholes: one for re-injection "Casaglia001" and two for pumping hot fluids. The microseismic network started, and still today, its monitoring activities with five vertical 2 Hz and one 3D seismometers model Mark products L4A/C distributed at reciprocal distances of about 5 to 7 km around the reservoir covering an area of 100 km^2. Since its beginning the monitoring activities proceeded almost continuously. However, due to technological limitations of the network HW, although sufficient to capture small magnitude earthquakes (near zero), the exponential increase of anthropogenic and electromagnetic noise degraded the monitoring capability of the network especially for small ones. To this end and as of 2007, the network control passed to the University of Ferrara, Department of Physics and Earth Sciences, the network HD for digitalisation and continuous data transmission was replaced with GURALP equipment's.. Since its establishment, few earthquakes occurred in the geothermal area with Ml 5 km. However, following the Emilia sequence of 2012, and as an example we present and discuss the local earthquake (Ml 2.5) occurred in Casaglia (Ferrara, Italy) on September 3, 2015, in the vicinity of the borehole Casaglia1 used for fluid re-injection. In this case, both INGV national network and OGS NE-Italy regional networks provided similar information, with hypocenter at about 5-6 km North of the reservoir edge and about 16 km of depth. However, the same event, relocated by using

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

    1992-10-01

    The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

    To present a novel and simple graphical approach to improve the presentation of the treatment ranking in a network meta-analysis (NMA) including multiple outcomes. NMA simultaneously compares many relevant interventions for a clinical condition from a network of trials, and allows ranking of the effectiveness and/or safety of each intervention. There are numerous ways to present the NMA results, which can challenge their interpretation by research users. The rank-heat plot is a novel graph that can be used to quickly recognize which interventions are most likely the best or worst interventions with respect to their effectiveness and/or safety for a single or multiple outcome(s) and may increase interpretability. Using empirical NMAs, we show that the need for a concise and informative presentation of results is imperative, particularly as the number of competing treatments and outcomes in an NMA increases. The rank-heat plot is an efficient way to present the results of ranking statistics, particularly when a large amount of data is available, and it is targeted to users from various backgrounds.

  5. Preparing for Emergency Situations

    2010-11-01

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

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

  8. Situational theory of leadership.

    1989-11-01

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

    The demographic and epidemiologic transition resulting from aging and the increase of life expectation means an increment related to chronic conditions. The healthcare systems contemporary crisis is characterized by the organization of the focus on fragmented systems turned to the acute conditions care, in spite of the chronic conditions prevalence, and by the hierarchical structure without communication flow among the different health care levels. Brazil health care situation profile is now presenting a triple burden of diseases, due to the concomitant presence of infectious diseases, external causes and chronic diseases. The solution is to restore the consistence between the triple burden of diseases on the health situation and the current system of healthcare practice, with the implantation of health care networks. The conclusion is that there are evidences in the international literature on health care networks that these networks may improve the clinical quality, the sanitation results and the user's satisfaction and the reduction of healthcare systems costs.

    1977-01-01

    The global water situation is assessed. Movement and distribution of water in the hydrologic cycle is described. Methods of appraising surface water, precipitation, evapotranspiration, groundwater, and water quality are reviewed. The reliability of such appraisals depends greatly on the adequacy of national water observation networks. Global water supplies and quality of lakes, reservoirs, and groundwater are estimated. The effects of runoff, climate, and human activities on supplies are briefly discussed. The use and demand of water for domestic, industrial, agricultural, hydroelectric, transportation, and recreational needs are assessed. Methods of projecting water demand and quality are reviewed. Demand and supply relationships for various regions of the world are presented. Socioeconomic, financial, technical, administrative, legal, and environmental considerations of these relationships are examined. By using available technology and institutional devices, the world water situation can be improved. (1 diagram, 3 graphs, 8 tables)

    The present study investigated whether engaging in sexy self-presentations on social network sites (SNSs) or exposure to sexy self-presentations on SNSs predicts the willingness to engage in sexting. A second aim of the present study was to investigate whether adolescent girls demonstrate stronger relationships between (exposure to) sexy online self-presentations on SNSs and willingness to sext than adolescent boys and young adult men and women. A two-wave panel survey among 953 Dutch adolescents (13-17 years old, 50.7% male) and 899 Dutch young adults (18-25 years old, 43.9% male) showed that engaging in sexy self-presentations on SNSs increased the willingness to engage in sexting, but only among adolescent girls. Exposure to sexy self-presentations of others did not predict the willingness to engage in sexting. The findings call for more research on the role of gender and age in the link between sexy self-presentation and sexting.

    It is often in the social networks where you detect the first signs of a potential crisis situation. Today, many companies decide to be present in social networks to communicate, listen and respond to their audiences openly with immediacy. A simple complaint is visible and propagates through the network in seconds, being capable of generating a negative impact on the corporate image of the organization. The same can happen to the contrary, ie, to praise the performance of a company, which may...

Canada today is our main partner and state support in the international arena. This is evidenced by the active position of Canada on the international stage in the Ukrainian crisis. After the illegal annexation of Crimea by Russia and the conflict in Donbas Canada has consistently supported Ukraine within the framework of international organizations (UN, OSCE, NATO, G7 and at the bilateral level. In addition, Canada has implemented economic and political sanctions against a number of Russian individuals and companies as well as representatives of the so-called «DNR» and «LNR» and separatist leaders. Relations with Canada is a promising destination for foreign policy strategy of Ukraine. Canada supports our country and contribute to its development, and helps to overcome the Ukrainian crisis.

    Cosmetics are consumer products intended to contribute to increasing quality of life and designed for long-term daily use. Due to such features of cosmetics, they are required to ensure quality and safety at a high level, as well as to perform well, in response to consumers' demands. Recently, the technology associated with nanomaterials has progressed rapidly and has been applied to various products, including cosmetics. For example, nano-sized titanium dioxide has been formulated in sunscreen products in pursuit of improving its performance. As some researchers and media have expressed concerns about the safety of nanomaterials, a vague feeling of anxiety has been raised in society. In response to this concern, the Japan Cosmetic Industry Association (JCIA) has begun original research related to the safety assurance of nanomaterials formulated in cosmetics, to allow consumers to use cosmetics without such concerns. This paper describes the activities of the JCIA regarding safety research on nanomaterials, including a survey of the actual usage of nanomaterials in cosmetics, analysis of the existence of nanomaterials on the skin, and assessment of skin carcinogenicity of nano-sized titanium dioxide. It also describes the international status of safety assurance and regulation regarding nanomaterials in cosmetics.

    Strand, P.

    2002-01-01

    There is currently a focus on radioactivity and the Arctic region. The reason for this is the high number of nuclear sources in parts of the Arctic and the vulnerability of Arctic systems to radioactive contamination. The Arctic environment is also perceived as a wilderness and the need for the protection of this wilderness against contamination is great. In 1991, the International Arctic Environmental Protection Strategy (IAEPS) was launched and the Arctic Monitoring and Assessment Programme (AMAP) established. AMAP is undertaking an assessment of the radioactive contamination of the Arctic and its radiological consequences. This paper summarises some of current knowledge about sources of radioactive contamination, vulnerability, exposure of man, and potential sources for radioactive contamination within Arctic and some views on the future needs for work concerning radioactivity in Arctic.

    The gasification of coal and/or residual fuels from refineries together with the use of combined cycle power generation systems represents a technically and economically feasible method for the conversion of poor quality fossil fuels into electric power. The conversion is accomplished with maximum respect for the severest environmental normatives. In addition, foreseen technical improvements for components and plant systems are expected to heighten the marketing potential of gasification/combined cycle power plants. After Italy's moratorium on nuclear energy, the passing eras of conventional fossil fuel and then combined cycle power plants, the need for highly competitive industrial production technologies and the urgency of nation-wide energy conservation appear to be ushering in the new era of gasification with combined cycles

Para tanto, discute como a participação das mulheres foi analisada nos fluxos migratórios e aborda o recente movimento de brasileiros para o exterior, descrevendo as trajetórias de homens e mulheres. O trabalho de campo, tal como a vida desses migrantes, dividiu-se entre dois lugares: a cidade de Criciúma (SC, no Brasil, e a região de Boston, nos Estados Unidos. Os dados coletados a partir das entrevistas e da observação participante têm revelado que as mulheres participam efetivamente desse processo, integrando e articulando redes de migração. Os dados também sugerem que a migração provoca rearranjos familiares e de gênero ao longo do processo.This paper intends to demonstrate that migratory process results not only from individual choices, but also from social networks (family, kingship, friendship, in which men and women are inserted. The work discusses data from fieldwork in Criciúma (SC and the Boston area, in United States. The data emerged from the interviews and participant observation show that women not only wait for their husbands or children, but also participate in the process, integrating and articulating migration networks. The data also highlighted the changes in the family and gender relationships, suggesting that the migratory process rearticulate these relationships. This study therefore evidences that other factors, along with the ones of economic nature, contribute for the decision of migrating and make the history of this flow.

    1993-12-01

    This report presents some aspects of the acoustical situation in the workrooms of the electricity building of the nuclear plant N4 of Chooz. It enables us to draw up a diagnosis of the present situation. This diagnosis will contribute to the choice of the technical solutions, at the conception of this type of building. A particular study is devoted to the kitchen of the building. This study shows the impact of a RRI (intermediary refrigeration circuit), which is responsible for a high noise level in this room. The fixation type of the pipe appears to be the cause of the annoyance. This study justifies the need for the uncoupling between this pipe type and the building structures, at the conception time. Noise levels measured in the different rooms are essentially induced by the ventilation networks. This levels are generally too high, compared with the objectives. This leads us to consider that the installation rules about the ventilation network are still to define. (authors). 7 figs., 2 annexes

    DEFF Research Database (Denmark)

    Quitzau, Maj-Britt; Petersen, Jens-Phillip

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

  5. Threat evaluation for impact assessment in situation analysis systems

    Science.gov (United States)

    Roy, Jean; Paradis, Stephane; Allouche, Mohamad

    2002-07-01

    Situation analysis is defined as a process, the examination of a situation, its elements, and their relations, to provide and maintain a product, i.e., a state of situation awareness, for the decision maker. Data fusion is a key enabler to meeting the demanding requirements of military situation analysis support systems. According to the data fusion model maintained by the Joint Directors of Laboratories' Data Fusion Group, impact assessment estimates the effects on situations of planned or estimated/predicted actions by the participants, including interactions between action plans of multiple players. In this framework, the appraisal of actual or potential threats is a necessary capability for impact assessment. This paper reviews and discusses in details the fundamental concepts of threat analysis. In particular, threat analysis generally attempts to compute some threat value, for the individual tracks, that estimates the degree of severity with which engagement events will potentially occur. Presenting relevant tracks to the decision maker in some threat list, sorted from the most threatening to the least, is clearly in-line with the cognitive demands associated with threat evaluation. A key parameter in many threat value evaluation techniques is the Closest Point of Approach (CPA). Along this line of thought, threatening tracks are often prioritized based upon which ones will reach their CPA first. Hence, the Time-to-CPA (TCPA), i.e., the time it will take for a track to reach its CPA, is also a key factor. Unfortunately, a typical assumption for the computation of the CPA/TCPA parameters is that the track velocity will remain constant. When a track is maneuvering, the CPA/TCPA values will change accordingly. These changes will in turn impact the threat value computations and, ultimately, the resulting threat list. This is clearly undesirable from a command decision-making perspective. In this regard, the paper briefly discusses threat value stabilization

    The wide spread of digital technology in the medical field has led to a demand for the high-quality, high-speed, and user-friendly digital image presentation system in the daily medical conferences. To fulfill this demand, we developed a presentation system for radiological and pathological images. It is composed of a super-high-definition (SHD) imaging system, a radiological image database (R-DB), a pathological image database (P-DB), and the network interconnecting these three. The R-DB consists of a 270GB RAID, a database server workstation, and a film digitizer. The P-DB includes an optical microscope, a four-million-pixel digital camera, a 90GB RAID, and a database server workstation. A 100Mbps Ethernet LAN interconnects all the sub-systems. The Web-based system operation software was developed for easy operation. We installed the whole system in NTT East Kanto Hospital to evaluate it in the weekly case conferences. The SHD system could display digital full-color images of 2048 x 2048 pixels on a 28-inch CRT monitor. The doctors evaluated the image quality and size, and found them applicable to the actual medical diagnosis. They also appreciated short image switching time that contributed to smooth presentation. Thus, we confirmed that its characteristics met the requirements.

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

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

  9. The application of transportation models in emergency situations: Example of a hypothetical city

    Full Text Available Emergency situations, where mass evacuation of people is present, are serious problem that is difficult to resolve. Such events have become more frequent in recent years. The transportation network is a key part of the infrastructure when it comes to events with disastrous consequences, because a large population of people must be effectively evacuated from densely populated urban areas. Therefore, requirements during an evacuation process are made in a relatively short period of time, and available capacity of the road network has become the main resource to be efficiently utilized in order to shorten the time required for evacuation. By using transportation model, the paper presents the simulation of the traffic in a situation when there is a need to evacuate large numbers of people, in order to propose measures that could be efficiently used.

    We introduce a multiparty quantum computation task over a network in a situation where the capacities of both the quantum and classical communication channels of the network are limited and a bottleneck occurs. Using a resource setting introduced by Hayashi [1], we present an efficient protocol for performing controlled-unitary operations between two input nodes and two output nodes over the butterfly network, one of the most fundamental networks exhibiting the bottleneck problem. This result opens the possibility of developing a theory of quantum network coding for multiparty quantum computation, whereas the conventional network coding only treats multiparty quantum communication.

It was only seven years later, in 1984, that ESO initiated the search for a future VLT site that ultimately led to the recommendation in favour of Paranal, the subsequent donation by the Chilean Government and the beginning of the construction, as described above. ESO has never had any doubt on the legality of this donation by the Chilean Government. The Organisation started the work at Paranal in full confidence that this generous act was correct and respected its condition, i.e. to start construction of the VLT observatory within a given time frame. However, in April 1993, when the work at Paranal was already quite advanced, a Chilean family brought a lawsuit against the Chilean State and ESO, claiming that a small part of the land (about 22 sq. km, including the very peak of Paranal) that was inscribed by the state in 1977, had been property of this family. The lawsuit is presently pending with the competent Chilean courts and it is not known when a final judgement will be given. In keeping with its status as an International Organisation and conforming to the international practice of such organisations, ESO decided not to become a party in this lawsuit. The Organisation, therefore, has restricted its involvement to merely invoking the immunity from lawsuit and jurisdiction to which it is entitled (see below). ESO believes that the issue of past ownership is an internal Chilean matter. Nevertheless, it has been widely reported that on January 30, 1995, in response to an appeal by the claimants, a Chambre of the Chilean Supreme Court issued a preliminary decision that may be interpreted as ordering to stop the construction of the VLT during an undetermined period of time. This would seriously delay the entire project and necessarily entail additional, substantial costs. ESO'S IMMUNITIES ESO's relations with its host state, the Republic of Chile, is governed by an international Convention ("Convenio"), signed in 1963 and ratified by the Chilean

    An application of various mobile communication systems to the electric power telecommunication network has been investigated. Among these, the customer information network by PHS (personal handy-phone system) has been proposed. Although great numbers of base stations are required for PHS, it can be applied as the customer information network by connecting to the power controller developed by the Central Research Institute of Electric Power Industry. The geostationary satellite telecommunication has been positively utilized by the electric power industry since the Hanshin-Awaji Great Earthquake. It can be used as the customer information network in the future. Since the radio access is a one-way communication, it cannot be applied to the electric power telecommunication network at present. It can be applied to the simple message communication or relatively low-speed data communication through the two-way communication. Public ground mobile telecommunication in the future includes various mobile telecommunication systems. To start the operation in 2000, the ITU (International Telecommunication Union) is making specifications common in the world. It is required to investigate the utilization as multipurpose systems. The network for PHS can be applied to the telecommunication network without optical cable. 20 refs., 5 figs., 3 tabs.

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

    Graabak, Ingeborg

    1997-01-01

    In Norway, it is expected that owners of electric distribution networks will be required to make it possible for the customers to change supplier each week. This report examines what consequences such a requirement will have for the network owners. An inquiry among nine network owners shows that at present changing supplier implies a great deal of manual work on the part of the network owner since many do not have computer based tools adapted to handle the situation. If the number of weekly changes of suppliers does not increase beyond a few percent of the network owner's total number of customers over 1 to 3 years, the network owner can cope with the situation. However, if for some reason the increase becomes larger, many network owners will have great problems because they lack the necessary computer tools. 1 table

  1. METHODOLOGICAL ELEMENTS OF SITUATIONAL ANALYSIS

    2016-07-01

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

The second principle is limit the discussed issues to such a piece of reality that can be possible for precise description. The third is to avoid introducing such information to the described reality that is not explicitly mentioned by linguistic means. The authors try to following these principles in the present paper. The paper is organized as follows. First, some samples of situations related to present tense are given together with examples of their expressions in four languages: English, (as a reference language and three Slavic languages, representing South slavonic languages (Bulgarian, West slavonic languages (Polish, and East slavonic languages (Russian. Within the same framework the next parts of the paper are constructed, supplying samples of using Past tenses and, finally, future tenses and modalities. The formal tools for description purposes are introduced stepwise, according to needs caused be the described reality.

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

  6. Epileptogenic networks and drug-resistant epilepsy: Present and future perspectives of epilepsy research-Utility for the epileptologist and the epilepsy surgeon

    Directory of Open Access Journals (Sweden)

    Jyotirmoy Banerjee

    2014-01-01

    Full Text Available A multidisciplinary approach is required to understand the complex intricacies of drug-resistant epilepsy (DRE. A challenge that neurosurgeons across the world face is accurate localization of epileptogenic zone. A significant number of patients who have undergone resective brain surgery for epilepsy still continue to have seizures. The reason behind this therapy resistance still eludes us. Thus to develop a cure for the difficult to treat epilepsy, we need to comprehensively study epileptogenesis. Till date, most of the studies on DRE is focused on undermining the abnormal functioning of receptors involved in synaptic transmission and reduced levels of antiepileptic drugs around there targets. But recent advances in imaging and electrophysiological techniques have suggested the role epileptogenic networks in the process of epileptogenesis. According to this hypothesis, the local neurons recruit distant neurons through complex oscillatory circuits, which further recruit more distant neurons, thereby generating a hypersynchronus neuronal activity. The epileptogenic networks may be confined to the lesion or could propagate to distant focus. The success of surgery depends on the precision by which the epileptogenic network is determined while planning a surgical intervention. Here, we summarize various modalities of electrophysiological and imaging techniques to determine the functionally active epileptogenic networks. We also review evidence pertaining to the proposed role of epileptogenic network in abnormal synaptic transmission which is one of the major causes of epileptiform activity. Elucidation of current concepts in regulation of synaptic transmission by networks will help develop therapies for epilepsy cases that cannot be managed pharmacologically.

    The network of social and health care has advanced since its inception. Furthermore, news services have been created and some resources have been adapted within the framework of respective health plans. This article presents the current situation of the different social and health resources in Catalonia, as well as the main changes that have occurred in recent years, more specifically in the period of the Health Plan 2011-2015. This period is characterised by an adaptation of the social and health network within the context of chronic care, for which the development of intermediate care resources has become the most relevant aspect. There is also a need to create a single long-term care sector in which the health care quality is guaranteed. Moreover, in this period, integral and cross-care level is promoted in the health system through a greater coordination between all different levels of care. The social and health network, due to its trajectory and expertise, plays a key role in the quality of care for people with social and medical needs. Copyright © 2017 SEGG.

    International Nuclear Information System (INIS)

    Lee, Hyun Chul; Seong, Poong Hyun

    2009-01-01

    Operators in nuclear power plants have to acquire information from human system interfaces (HSIs) and the environment in order to create, update, and confirm their understanding of a plant state, or situation awareness, because failures of situation assessment may result in wrong decisions for process control and finally errors of commission in nuclear power plants. Quantitative or prescriptive models to predict operator's situation assessment in a situation, the results of situation assessment, provide many benefits such as HSI design solutions, human performance data, and human reliability. Unfortunately, a few computational situation assessment models for NPP operators have been proposed and those insufficiently embed human cognitive characteristics. Thus we proposed a new computational situation assessment model of nuclear power plant operators. The proposed model incorporating significant cognitive factors uses a Bayesian belief network (BBN) as model architecture. It is believed that communication between nuclear power plant operators affects operators' situation assessment and its result, situation awareness. We tried to verify that the proposed model represent the effects of communication on situation assessment. As the result, the proposed model succeeded in representing the operators' behavior and this paper shows the details

Although the rate of investment into real sectors of Russian economics mid 2000 was higher compared to the previous period, annual investment amounts were much lower than in 1990. At present, highest investment amounts are directed to industry extractive branches and to the commerce. Amounts invested to various economy branches do not correspond to their contribution to the country’sGross Added Product; particularly underinvested are manufacturing industry branches. At present, foreign share in the country economy total investment makes 15–18%. Recently, most interesting for foreigners was investment to machine-building branches with overwhelming part (for example, 90% in 2007–2008 of foreign investment into the machine-building industry being directed to creation of new automobile plants. Today, first place in the list of foreign investors’ preferences in Russia is taken by the machine-tool construction sector.

    2007-05-01

    Full Text Available Abstract Background There is an increasing interest to model biochemical and cell biological networks, as well as to the computational analysis of these models. The development of analysis methodologies and related software is rapid in the field. However, the number of available models is still relatively small and the model sizes remain limited. The lack of kinetic information is usually the limiting factor for the construction of detailed simulation models. Results We present a computational toolbox for generating random biochemical network models which mimic real biochemical networks. The toolbox is called Random Models for Biochemical Networks. The toolbox works in the Matlab environment, and it makes it possible to generate various network structures, stoichiometries, kinetic laws for reactions, and parameters therein. The generation can be based on statistical rules and distributions, and more detailed information of real biochemical networks can be used in situations where it is known. The toolbox can be easily extended. The resulting network models can be exported in the format of Systems Biology Markup Language. Conclusion While more information is accumulating on biochemical networks, random networks can be used as an intermediate step towards their better understanding. Random networks make it possible to study the effects of various network characteristics to the overall behavior of the network. Moreover, the construction of artificial network models provides the ground truth data needed in the validation of various computational methods in the fields of parameter estimation and data analysis.

    The brain is organized into networks composed of spatially separated anatomical regions exhibiting coherent functional activity over time. Two of these networks (the default mode network, DMN, and the task positive network, TPN) have been implicated in the performance of a number of cognitive tasks. To directly examine the stable relationship between network connectivity and behavioral performance, high temporal resolution functional magnetic resonance imaging (fMRI) data were collected during the resting state, and behavioral data were collected from 15 subjects on different days, exploring verbal working memory, spatial working memory, and fluid intelligence. Sustained attention performance was also evaluated in a task interleaved between resting state scans. Functional connectivity within and between the DMN and TPN was related to performance on these tasks. Decreased TPN resting state connectivity was found to significantly correlate with fewer errors on an interrupter task presented during a spatial working memory paradigm and decreased DMN/TPN anti-correlation was significantly correlated with fewer errors on an interrupter task presented during a verbal working memory paradigm. A trend for increased DMN resting state connectivity to correlate to measures of fluid intelligence was also observed. These results provide additional evidence of the relationship between resting state networks and behavioral performance, and show that such results can be observed with high temporal resolution fMRI. Because cognitive scores and functional connectivity were collected on nonconsecutive days, these results highlight the stability of functional connectivity/cognitive performance coupling.

In the metro core, we should consider the network should evolved towards the Mesh architecture with ASON function to realize the fast protection and restoration, quick end-to-end service provision, and high capacity cross-connect matrix etc. In the access layer, the network should have the ability to access the 3G services such as ATM interface with IMA function. In addition, the traffic grooming should be provided to improve the bandwidth utility. In this paper, first we present the MCC network situation, the network planning model will be introduced. Then we present the topology architecture, node capacity and traffic forecast. At last, based on our analysis, we will give a total solution to MCC to build their metro optical network toward to the mesh network with the consideration of 3G services.

  4. Integrated situational awareness for cyber attack detection, analysis, and mitigation

    Real-time cyberspace situational awareness is critical for securing and protecting today's enterprise networks from various cyber threats. When a security incident occurs, network administrators and security analysts need to know what exactly has happened in the network, why it happened, and what actions or countermeasures should be taken to quickly mitigate the potential impacts. In this paper, we propose an integrated cyberspace situational awareness system for efficient cyber attack detection, analysis and mitigation in large-scale enterprise networks. Essentially, a cyberspace common operational picture will be developed, which is a multi-layer graphical model and can efficiently capture and represent the statuses, relationships, and interdependencies of various entities and elements within and among different levels of a network. Once shared among authorized users, this cyberspace common operational picture can provide an integrated view of the logical, physical, and cyber domains, and a unique visualization of disparate data sets to support decision makers. In addition, advanced analyses, such as Bayesian Network analysis, will be explored to address the information uncertainty, dynamic and complex cyber attack detection, and optimal impact mitigation issues. All the developed technologies will be further integrated into an automatic software toolkit to achieve near real-time cyberspace situational awareness and impact mitigation in large-scale computer networks.

    1980-01-01

    Visits to four utilities concerned with the use of DSG power sources on their distribution networks yielded useful impressions of present and future approaches to the integration of DSGs into electrical distribution network. Different approaches to future utility systems with DSG are beginning to take shape. The new DSG sources will be in decentralized locations with some measure of centralized control. The utilities have yet to establish firmly the communication and control means or their organization. For the present, the means for integrating the DSGs and their associated monitoring and control equipment into a unified system have not been decided.

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

  18. Mexican energy situation and perspectives

    International Nuclear Information System (INIS)

    Pnce, A.

    1978-01-01

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

    Sun, Xin; Liu, Yan-Heng; Han, Jia-Wei; Liu, Xue-Jie; Li, Bin; Li, Jin

    2012-01-01

    In this paper, a mathematical model for social network worm spreading is presented from the viewpoint of social engineering. This model consists of two submodels. Firstly, a human behavior model based on game theory is suggested for modeling and predicting the expected behaviors of a network user encountering malicious messages. The game situation models the actions of a user under the condition that the system may be infected at the time of opening a malicious message. Secondly, a social network accessing model is proposed to characterize the dynamics of network users, by which the number of online susceptible users can be determined at each time step. Several simulation experiments are carried out on artificial social networks. The results show that (1) the proposed mathematical model can well describe the spreading dynamics of social network worms; (2) weighted network topology greatly affects the spread of worms; (3) worms spread even faster on hybrid social networks

  13. Athletic Training Clinical Instructors as Situational Leaders.

    Science.gov (United States)

    Meyer, Linda Platt

    2002-12-01

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

  14. Interconnected networks

    CERN Document Server

    2016-01-01

    This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

    2005-10-01

    Full Text Available A novel method for the analysis and interpretation of data that describes the interaction between trainee network managers and a network management training tool is presented. A simulation based approach is currently being used to train network managers, through the use of a simulated network. The motivation is to provide a tool for exposing trainees to a life like situation without disrupting a live network. The data logged by this system describes the detailed interaction between trainee network manager and simulated network. The work presented here provides an analysis of this interaction data that enables an assessment of the capabilities of the trainee network manager as well as an understanding of how the network management tasks are being approached. A neural network architecture is implemented in order to perform an exploratory data analysis of the interaction data. The neural network employs a novel form of continuous self-organisation to discover key features in the data and thus provide new insights into the learning and teaching strategies employed.

    Background Multimorbidity, according to the World Health Organization, exists when there are two or more chronic conditions in one patient. This definition seems inaccurate for the holistic approach to Family Medicine (FM) and long-term care. To avoid this pitfall the European General Practitioners Research Network (EGPRN) designed a comprehensive definition of multimorbidity using a systematic literature review. Objective To translate that English definition into European languages and to validate the semantic, conceptual and cultural homogeneity of the translations for further research. Method Forward translation of the EGPRN’s definition of multimorbidity followed by a Delphi consensus procedure assessment, a backward translation and a cultural check with all teams to ensure the homogeneity of the translations in their national context. Consensus was defined as 70% of the scores being higher than 6. Delphi rounds were repeated in each country until a consensus was reached Results 229 European medical expert FPs participated in the study. Ten consensual translations of the EGPRN comprehensive definition of multimorbidity were achieved. Conclusion A comprehensive definition of multimorbidity is now available in English and ten European languages for further collaborative research in FM and long-term care. PMID:25607642

    Full Text Available In this paper, a multi-period model for blood supply chain in emergency situation is presented to optimize decisions related to locate blood facilities and distribute blood products after natural disasters. In disastrous situations, uncertainty is an inseparable part of humanitarian logistics and blood supply chain as well. This paper proposes a robust network to capture the uncertain nature of blood supply chain during and after disasters. This study considers donor points, blood facilities, processing and testing labs, and hospitals as the components of blood supply chain. In addition, this paper makes location and allocation decisions for multiple post disaster periods through real data. The study compares the performances of “p-robust optimization” approach and “robust optimization” approach and the results are discussed.

  13. [Support psychotherapy in traumatic situations].

    Pérez-Sales, Pau; Vázquez Valverde, Carmelo

    2003-12-01

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

  15. A situational approach to the measurement of safety culture

    International Nuclear Information System (INIS)

    Semmer, N.; Regennass, A.

    1997-01-01

    Values and social norms are the main target of most approaches to the study of safety culture and many existing survey methodologies directly ask for these norms and values. However, a number of considerations point to the dangers of limiting the evaluation of safety culture to the analysis of these responses. Therefore the necessity is stressed to also consider how actual situations activate norms and behaviours. This relates to the fact that in any given situation both aspects of the appraisal of reality are present: the objective definition of the situation and its personal evaluation. The latter not only reflects the ''official'' norms and values but also ''basic underlying assumptions''. The situational approach introduced in this paper confronts people with situations which contain a dilemma with conflicting social norms and where various costs and benefits are associated with different types of behaviour. In addition, the prerequisites and limitations of the situational approach are discussed. (author). 9 refs, 1 fig

    Full Text Available It is often in the social networks where you detect the first signs of a potential crisis situation. Today, many companies decide to be present in social networks to communicate, listen and respond to their audiences openly with immediacy. A simple complaint is visible and propagates through the network in seconds, being capable of generating a negative impact on the corporate image of the organization. The same can happen to the contrary, ie, to praise the performance of a company, which may affect the creation or strengthening of the good reputation of the company. However, we know that this does not happen with the same intensity. In this paper we analyze the decisions and actions of two opposing companies, Nestlé and Panrico, in front of a possible crisis situation.

    2015-01-01

    The recent trends in software-defined networking (SDN) and network function virtualization (NFV) are boosting the advance of software-based packet processing and forwarding on commodity servers. Although performance has traditionally been the challenge of this approach, this situation changes with modern server platforms. High performance load balancers, proxies, virtual switches and other network functions can be now implemented in software and not limited to specialized commercial hardware, thus reducing cost and increasing the flexibility. In this paper we design a lossless software-based switch for high bandwidth data acquisition (DAQ) networks, using the ATLAS experiment at CERN as a case study. We prove that it can effectively solve the incast pathology arising from the many-to-one communication pattern present in DAQ networks by providing extremely high buffering capabilities. We evaluate this on a commodity server equipped with twelve 10 Gbps Ethernet interfaces providing a total bandwidth of 120 Gbps...

    International Nuclear Information System (INIS)

    2012-05-01

    Energy production and distribution play a key-role in the evolution of our societies. The resources coming from the Earth's crust are limited and our energy production system has negative impacts on the environment which have to be minimized. Political projects have to take these constraints into consideration with a long-term vision. The French Society of Physics (SFP) approached the experts of the Energy-Environment commission to shade light on the energy debate in France and in the rest of the world. A precise and brief analysis of the French and worldwide energy situation is presented in a first part (situation and prospective, costs, benefits and risks, decarbonization, R and D, energy saving and conservation..). Then, a series of 10 thematic information sheets summarizes different economical, environmental and political aspects of the energy question: resources and reserves, environmental impact of various power generation sources, risks, costs and benefits of the different energy industries, energy costs, production irregularity management, networks and storage facilities, European transportation networks and super-networks for electricity, gas, petroleum and CO 2 , consumption abatement, decarbonization strategies, energy policy choices for France from 2010 to 2050

    2018-02-01

    Distributed energy resources (DERs) are increasingly penetrating the energy system which is driven by climate and sustainability goals. These technologies are mostly connected to low- voltage electrical networks and change the demand and supply situation in these networks. This can cause critical network states. Network topologies vary significantly and depend on several conditions including geography, historical development, network design or number of network connections. In the past, only some of these aspects were taken into account when estimating the network investment needs for Germany on the low-voltage level. Typically, fixed network topologies are examined or a Monte Carlo approach is used to quantify the investment needs at this voltage level. Recent research has revealed that DERs differ substantially between rural, suburban and urban regions. The low-voltage network topologies have different design concepts in these regions, so that different network topologies have to be considered when assessing the need for network extensions and investments due to DERs. An extension algorithm is needed to calculate network extensions and investment needs for the different typologies of generic low-voltage networks. We therefore present a new algorithm, which is capable of calculating the extension for generic low-voltage networks of any given topology based on voltage range deviations and thermal overloads. The algorithm requires information about line and cable lengths, their topology and the network state only. We test the algorithm on a radial, a loop, and a heavily meshed network. Here we show that the algorithm functions for electrical networks with these topologies. We found that the algorithm is able to extend different networks efficiently by placing cables between network nodes. The main value of the algorithm is that it does not require any information about routes for additional cables or positions for additional substations when it comes to estimating

    To examine skin and soft tissue infections presenting at 4 primary care clinics and assess if historical risk factors and examination findings were associated with a positive methicillin-resistant Staphylococcus aureus (MRSA) culture. During the 10-month observational study (April 2007 through January 2008), physicians in 5 practices across South Texas collected history, physical examination findings, culture results, and antibiotic(s) prescribed for all patients presenting with a skin or soft tissue infection. Analyses were conducted to determine the relationship between historical indicators, location of lesions, and examination findings with a positive MRSA culture. Across 4 practices, 164 cases of skin and soft tissue infections were collected during 10 months. Of the 94 with a culture, 63 (67%) were MRSA positive. Patients working in or exposed to a health care setting were more likely to have a culture positive for MRSA, as were those presenting with an abscess. MRSA-positive lesions were also significantly smaller in size. Because of the high prevalence of MRSA skin and soft tissue infections among patients presenting to family physicians, presumptive treatment for MRSA may be indicated. However, increasing levels of resistance to current antibiotics is concerning and warrants development of alternative management strategies.

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

    1990-08-01

    A practical approach to dealing with combinatorial decision problems and uncertainties associated with electronic combat through the use of networks of high-level functional elements called abductive networks is presented. It describes the application of the Abductory Induction Mechanism (AIMTM) a supervised inductive learning tool for synthesizing polynomial abductive networks to the electronic combat problem domain. From databases of historical expert-generated or simulated combat engagements AIM can often induce compact and robust network models for making effective real-time electronic combat decisions despite significant uncertainties or a combinatorial explosion of possible situations. The feasibility of applying abductive networks to realize advanced combat decision aiding capabilities was demonstrated by applying AIM to a set of electronic combat simulations. The networks synthesized by AIM generated accurate assessments of the intent lethality and overall risk associated with a variety of simulated threats and produced reasonable estimates of the expected effectiveness of a group of electronic countermeasures for a large number of simulated combat scenarios. This paper presents the application of abductive networks to electronic combat summarizes the results of experiments performed using AIM discusses the benefits and limitations of applying abductive networks to electronic combat and indicates why abductive networks can often result in capabilities not attainable using alternative approaches. 1.

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

    Current mobile devices allow the execution of sophisticated applications with the capacity for identifying the user situation, which can be helpful in treatments of mental disorders. In this paper, we present SituMan , a solution that provides situation awareness to MoodBuster , an ecological momentary assessment and intervention mobile application used to request self-assessments from patients in depression treatments. SituMan has a fuzzy inference engine to identify patient situations using context data gathered from the sensors embedded in mobile devices. Situations are specified jointly by the patient and mental health professional, and they can represent the patient's daily routine (e.g., "studying", "at work", "working out"). MoodBuster requests mental status self-assessments from patients at adequate moments using situation awareness. In addition, SituMan saves and displays patient situations in a summary, delivering them for consultation by mental health professionals. A first experimental evaluation was performed to assess the user satisfaction with the approaches to define and identify situations. This experiment showed that SituMan was well evaluated in both criteria. A second experiment was performed to assess the accuracy of the fuzzy engine to infer situations. Results from the second experiment showed that the fuzzy inference engine has a good accuracy to identify situations.

    Liang, Xiaoming; Liu, Zonghua; Li, Baowen

    2009-10-01

    We present a network model of coupled oscillators to study how a weak signal is transmitted in complex networks. Through both theoretical analysis and numerical simulations, we find that the response of other nodes to the weak signal decays exponentially with their topological distance to the signal source and the coupling strength between two neighboring nodes can be figured out by the responses. This finding can be conveniently used to detect the topology of unknown network, such as the degree distribution, clustering coefficient and community structure, etc., by repeatedly choosing different nodes as the signal source. Through four typical networks, i.e., the regular one dimensional, small world, random, and scale-free networks, we show that the features of network can be approximately given by investigating many fewer nodes than the network size, thus our approach to detect the topology of unknown network may be efficient in practical situations with large network size.

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

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

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

    An important part of the workshop was a series of invited presentations. The presentations were intended to both provide the participants with an understanding of various organisational approaches and activities as well as to stimulate the exchange of ideas during the small group discussion sessions. The presentation subjects ranged from current organisational regulations and licensee activities to new organisational research and the benefits of viewing organisations from a different perspective. There were more than a dozen invited presentations. The initial set of presentations gave the participants an overview of the background, structure, and aims of the workshop. This included a short presentation on the results from the regulatory responses to the pre-workshop survey. Representatives from four countries (Sweden, Canada, Finland, and the United Kingdom) expanded upon their survey responses with detailed presentations on both regulatory and licensee safety-related organisational activities in their countries. There were also presentations on new research concerning how to evaluate safety critical organisations and on a resilience engineering perspective to safety critical organisations. Below is the list of the presentations, the slides of which being available in Appendix 2: 1 - Workshop Welcome (Per-Olof Sanden); 2 - CSNI Working Group on Human and Organisational Factors (Craig Reiersen); 3 - Regulatory expectations on justification of suitability of licensee organisational structures, resources and competencies (Anne Edland); 4 - Justifying the suitability of licensee organisational structures, resources and competencies (Karl-Fredrik Ingemarsson); 5 - Nuclear Organisational Suitability in Canada (Andre Bouchard); 6 - Designing and Resourcing for Safety and Effectiveness (Germaine Watts); 7 - Organisational Suitability - What do you need and how do you know that you've got it?

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

    Purpose The purpose of this paper is to present a case study of the World Health Organization's Global Healthcare Workforce Alliance (GHWA). Based on a commissioned evaluation of GHWA, it applies network theory and key concepts from systems thinking to explore network emergence, effectiveness, and evolution to over a ten-year period. The research was designed to provide high-level strategic guidance for further evolution of global governance in human resources for health (HRH). Design/methodology/approach Methods included a review of published literature on HRH governance and current practice in the field and an in-depth case study whose main data sources were relevant GHWA background documents and key informant interviews with GHWA leaders, staff, and stakeholders. Sampling was purposive and at a senior level, focusing on board members, executive directors, funders, and academics. Data were analyzed thematically with reference to systems theory and Shiffman's theory of network development. Findings Five key lessons emerged: effective management and leadership are critical; networks need to balance "tight" and "loose" approaches to their structure and processes; an active communication strategy is key to create and maintain support; the goals, priorities, and membership must be carefully focused; and the network needs to support shared measurement of progress on agreed-upon goals. Shiffman's middle-range network theory is a useful tool when guided by the principles of complex systems that illuminate dynamic situations and shifting interests as global alliances evolve. Research limitations/implications This study was implemented at the end of the ten-year funding cycle. A more continuous evaluation throughout the term would have provided richer understanding of issues. Experience and perspectives at the country level were not assessed. Practical implications Design and management of large, complex networks requires ongoing attention to key issues like leadership

    In this thesis, we present Bayesian state estimation and machine learning methods for predicting traffic situations. The cognitive ability to assess situations and behaviors of traffic participants, and to anticipate possible developments is an essential requirement for several applications in the traffic domain, especially for self-driving cars. We present a method for learning behavior models from unlabeled traffic observations and develop improved learning methods for decision trees.

  16. Thoughts on the Postpartum Situation

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

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

  18. The future energy situation in the Netherlands

    International Nuclear Information System (INIS)

    1980-01-01

    This book is the result of a study into the future energy situation in the Netherlands, performed by the electricity companies in the country. The first five chapters sketch the framework within which energy policy is currently forced to operate. Further technical and physical conditions are considered in the following six chapters, including environmental and safety aspects. A prognosis for energy demand in the Netherlands until the end of the century is presented and five different scenarios are discussed, as means of supplying this demand. Nuclear energy is one of the sources considered throughout the text. (C.F.)

    With increased human activity in space, the risk of re-entry and collision between space objects is constantly increasing. Hence, the need for space situational awareness (SSA) programs has been acknowledged by many experienced space agencies. Optical and radar sensors, which enable the surveillance and tracking of space objects, are the most important technical components of SSA systems. In particular, combinations of radar systems and optical sensor networks play an outstanding role in SSA programs. At present, Korea operates the optical wide field patrol network (OWL-Net), the only optical system for tracking space objects. However, due to their dependence on weather conditions and observation time, it is not reasonable to use optical systems alone for SSA initiatives, as they have limited operational availability. Therefore, the strategies for developing radar systems should be considered for an efficient SSA system using currently available technology. The purpose of this paper is to analyze the performance of a radar system in detecting and tracking space objects. With the radar system investigated, the minimum sensitivity is defined as detection of a 1-m2 radar cross section (RCS) at an altitude of 2,000 km, with operating frequencies in the L, S, C, X or Ku-band. The results of power budget analysis showed that the maximum detection range of 2,000 km, which includes the low earth orbit (LEO) environment, can be achieved with a transmission power of 900 kW, transmit and receive antenna gains of 40 dB and 43 dB, respectively, a pulse width of 2 ms, and a signal processing gain of 13.3 dB, at a frequency of 1.3 GHz. We defined the key parameters of the radar following a performance analysis of the system. This research can thus provide guidelines for the conceptual design of radar systems for national SSA initiatives.
