    An image processing system fitting in an X-ray television circuit for tomography is described. The profiles registered by the X-ray television circuit are projected on the screen of an afterglow cathode ray tube which registration is convoluted in an analogue system with the help of either a one-dimensional or a two-dimensional convolution function after which it is stored or processed further such that a clear tomogram is obtained

This paper discussed the construction of the image of the candidate of the Institutional Revolutionary Party (PRI, Enrique Peña Nieto, during the last mexican presidential election, for five vehicles online local news. The newspapers were analyzed daily by the Electoral Communication Research Group, Federal University of Paraná (UFPR during the election period of 73 days, generating 365 reports qualiquantitatives. As Mexico is comprised of a population of very heterogeneous ethnic origin, religion that highly values and is based on traditional moral values, we seek to outline what the main values of the candidate are highlighted by the press. Furthermore, we aim to identify which of the feelings of 'empathy, projection and identification', the press related to the then-candidate. With the data, we can identify which picture Peña Nieto was designed by Mexican press during the period.

  5. THE SOCIAL CONSTRUCTION OF THE PUBLIC HEALTH

    Directory of Open Access Journals (Sweden)

    N. G. Osipova

    2016-01-01

    Full Text Available The article analyzes the role of sociology in the scientific management of society — namely — the social construction aimed at the prevention of adverse events and the creation of social realities desirable for the individual and society. One of the areas of social reality, as well as the most important sphere of social life which are subject to social construction is public health. Public health is considered as an integrated expression of the dynamics of individual levels of the health of all members of society. The author emphasizes that the public health of the people is formed by the interaction of two groups of factors — endogenous (sex, biological age, race, body type, heredity and type of the human nervous system and exogenous (natural and social factors. The last are created by people themselves in the course of their ability to live and are operated, that is socially designed. The author analyzes the negative processes related to public health, the most important of which is a complex situation in the health system, lack of faith in the possibility of human medicine. An equally important role belongs to the deterioration of environmental significant share of people’s living conditions and social stress. If earlier scientists did not specify, in what degree of threat of infringement of global ecosystems are connected with a state of health and features of diseases of the population now it is established that various forms of irreversible change of environment are directly dangerous to public health. From an antiquity the effect of discrepancy of the wished (abstractly and actually arising future wished (abstractly — effect of human activity is known: people wish one, however actually all terminates differently, practically, on the contrary. And these characteristics of a public sincere, mental condition can be extremely inconsistent in relation to knowledge. They are the basis of so-called “involuntary behaviors

  9. Moving image compression and generalization capability of constructive neural networks

    Science.gov (United States)

    Ma, Liying; Khorasani, Khashayar

    2001-03-01

    To date numerous techniques have been proposed to compress digital images to ease their storage and transmission over communication channels. Recently, a number of image compression algorithms using Neural Networks NNs have been developed. Particularly, several constructive feed-forward neural networks FNNs have been proposed by researchers for image compression, and promising results have been reported. At the previous SPIE AeroSense conference 2000, we proposed to use a constructive One-Hidden-Layer Feedforward Neural Network OHL-FNN for compressing digital images. In this paper, we first investigate the generalization capability of the proposed OHL-FNN in the presence of additive noise for network training and/ or generalization. Extensive experimental results for different scenarios are presented. It is revealed that the constructive OHL-FNN is not as robust to additive noise in input image as expected. Next, the constructive OHL-FNN is applied to moving images, video sequences. The first, or other specified frame in a moving image sequence is used to train the network. The remaining moving images that follow are then generalized/compressed by this trained network. Three types of correlation-like criteria measuring the similarity of any two images are introduced. The relationship between the generalization capability of the constructed net and the similarity of images is investigated in some detail. It is shown that the constructive OHL-FNN is promising even for changing images such as those extracted from a football game.

    This article argues for the need for foresight and planning to achieve sustainable development in the construction of public buildings. Reasons why sustainable development fails are highlighted, and the key factors that go to make a development sustainable are listed and involve the choice and layout of the site, site services, the fitting of spaces to the required purpose, the arrangement of rooms to achieve maximum use of natural light, heat and air, and the choice of construction materials and finishes. The balancing of short and long-term costs, and the use of life-cycle costs in every project are discussed.

  13. The development of public and private construction procurement systems in the Malaysian construction industry

    Directory of Open Access Journals (Sweden)

    Mastura Jaafar

    2012-12-01

    Full Text Available As demand on building construction projects rises, various procurement methods have been adapted to suit with unique project requirements. However, poor industry performance and rapid developments within it indicate the need for a research on the procurement systems in the industry. In order to explore the development of procurement systems in Malaysia, a discussion on different economic phases which influence the routes of procurement systems and its evolution in Malaysia's construction industry is initiated. Subsequently, based on a questionnaire survey collected from 73 public and 68 private parties, the significant and dominant role of traditional procurement system used by both the public and private sectors in Malaysia can be confirmed. Further, compared to the public sector, the private sector is observed to be more aggressive in adapting alternative systems such as design and build (D&B and Turnkey. Further elaboration on the research findings is covered in the discussion section.

    A method for constructing an object support based on K-means clustering of the object-intensity distribution is newly presented in diffractive imaging. This releases the adjustment of unknown parameters in the support construction, and it is well incorporated with the Gerchberg and Saxton diagram. A simple numerical simulation reveals that the proposed method is effective for dynamically constructing the support without an initial prior support.

    2009-11-01

    Full Text Available One of the possible models of the construction and use of sports objects, especi- ally indoor facilities (sports centres, halls, swimming pools, shooting alleys and others is the cooperation of the public and private sector, by the investment model of PPP (Pu- blic-Private Partnership. PPP (Public-Private Partnership construction is the new form of securing civil works, already known in the developed countries, in which the job of planning, construc- tion, functioning and financing is done by the private sector – in the scope of a precisely elaborated cooperation with the state. The state engages the private sector for the administering of the civil works. By public adverstisements and contests they will find the investors who accept the administe- ring of certain public works by themselves or with the help of project partners with their own resources (with 60-85% of bank loans, secure the conditions for conducting certain services (by using the objects, halls, etc until the expiration of the agreed deadline. The essence of PPP construction is the fact that an investor from the private sec- tor, chosen through a contest, realizes the project using its own means. The object beco- mes the property of the investor and it secures the regular functioning of the object with exclusive rights. The income from the functioning belongs to the investor, in return the costs of the functioning of the object, the upkeep, as well as the costs of the personnel and public utilities are the responsibility of the investor. The public use of the object is realised by the means that the authorised ministry and the partner from the contest in an agreement of the realization and functioning of the object accurately define the time of maintenance and the duration of the services on the behalf of social interest. From the time specified in the agreement the investor doesn’t charge precisely defined users for general and specific services. As Sebia, with all its

  20. Constructing public oral health policies in Brazil: issues for reflection.

    Science.gov (United States)

    Soares, Catharina Leite Matos

    2012-01-01

    This paper addresses the construction of public oral health policies in Brazil by reviewing the available literature. It includes a discussion of the social responses given by the Brazilian State to oral health policies and the relationship of these responses with the ideological oral health movements that have developed globally, and that have specifically influenced oral health policies in Brazil. The influence of these movements has affected a series of hegemonic practices originating from both Market Dentistry and Preventive and Social Dentistry in Brazil. Among the state activities that have been set into motion, the following stand out: the drafting of a law to regulate the fluoridation of the public water supply, and the fluoridation of commercial toothpaste in Brazil; epidemiological surveys to analyze the status of the Brazilian population's oral health; the inclusion of oral health in the Family Health Strategy (Estratégia de Saúde da Família - ESF); the drawing up of the National Oral Health Policy, Smiling Brazil (Brasil Sorridente). From the literature consulted, the progressive expansion of state intervention in oral health policies is observed. However, there remains a preponderance of hegemonic "dental" practices reproduced in the Unified Public Health Service (Sistema Único de Saúde - SUS) and the Family Health Strategy.

  2. The selling of Sellafield (the public image)

    International Nuclear Information System (INIS)

    White, David.

    1986-01-01

    The advertising campaign planned to restore the public image of Sellafield is discussed. Two aspects of the Sellafield site are being promoted especially, the first is that the discharges of long life radioactivity are being reduced. The second is the 'site accessibility' of Sellafield -BNFL is trying to encourage visitors to see for themselves what goes on at Sellafield. There is evidence that this will allay the fears and suspicions of the public. It is suggested, however, that providing information about nuclear power may be counter-productive as the concept of nuclear disaster may receive greater attention. The Sellafield site is difficult to promote whilst it continues to suffer leaks and it is suggested that the only way to promote Sellafield successfully may be by appealing to nationalism as the French have done in their nuclear campaign.

  3. Application of MCM image construction to IRAS comet observations

    Science.gov (United States)

    Schlapfer, Martin F.; Walker, Russell G.

    1994-01-01

    There is a wealth of IRAS comet data, obtained in both the survey and pointed observations modes. However, these measurements have remained largely untouched due to difficulties in removing instrumental effects from the data. We have developed a version of the Maximum Correlation Method for Image Construction algorithm (MCM) which operates in the moving coordinate system of the comet and properly treats both real cometary motion and apparent motion due to spacecraft parallax. This algorithm has been implemented on a 486/33 PC in FORTRAN and IDL codes. Preprocessing of the IRAS CRDD includes baseline removal, deglitching, and removal of long tails due to dielectric time constants of the detectors. The resulting images are virtually free from instrumental effects and have the highest possible spatial resolution consistent with the data sampling. We present examples of high resolution IRAS images constructed from survey observations of Comets P/Tempel 1 and P/Tempel 2, and pointed observations of IRAS-Araki-Alcock.

  5. The image of you: constructing nursing identities in YouTube.

    Science.gov (United States)

    Kelly, Jacinta; Fealy, Gerard M; Watson, Roger

    2012-08-01

    This article is a report on a descriptive study of nursing identity as constructed in the Web 2.0 site YouTube. Public images of the nurse carry stereotypes that rely on the taken for granted gender category of the nurse as woman. Nursing images represent a form of public discourse that has the capacity to construct nursing identity. Critical discourse analysis was used to describe, analyse and explain how nurse and nursing identity were constructed in a purposive sample of ten video clips accessed on 17 and 18 July 2010. The ten most-viewed videos depicting the nurse and nursing on YouTube offered narratives that constructed three distinct nursing identity types, namely nurse as 'a skilled knower and doer', nurse as 'a sexual plaything' and nurse as 'a witless incompetent' individual. Nursing identities recoverable from the texts of YouTube images propagate both favourable and derogatory nursing stereotypes. To mitigate the effects of unfavourable nursing stereotypes in such areas as interprofessional working and clinical decision-making, nursing professional bodies need to act to protect the profession from unduly immoderate representations of the nurse and to support nurses in their efforts to maximize opportunities afforded by YouTube to promote a counter discourse. © 2011 Blackwell Publishing Ltd.

    Gomes, Antonio Marcos Tosoli; Oliveira, Denize Cristina de

    2005-01-01

    The object of this study is the professional image constructed by public health nurses and the objective is to describe and analyze the professional images present in the representations of nurses who deliver direct care to this clientele. The theoretical-methodological reference framework adopted was Social Representations Theory. A qualitative study was developed in Petrópolis-Rio de Janeiro/Brazil, through in-depth interviews with 30 nurses. Alceste 4.5 software was used for the lexical analysis. The results reveal the existence of a professional self-image with three groups of meanings: being a reference for the team, the non-specific image and the image of plaster; and a professional hetero-image with four groups of meanings: administrator, invisible, positive image and superposition. The study of the professional image reflects the construction of the nurse's identity in itself and emphasizes Social Representations Theory as a useful tool for nursing research development.

  13. Construction of a homogeneous phantom for radiographic image standardization

    International Nuclear Information System (INIS)

    Pina, Diana Rodrigues de

    1996-01-01

    The principle of radiodiagnosis consists in the fact the X-ray beam is attenuated at different degrees by distinct tissues. For this reason, the anatomical structures have distinct radiological opacities, that produce the radiographic image. The progresses in radiology are related to the development if new radiographic image formation systems that enable an amplification in the quality, with low dose and/or risk to the patient. The objective of this work is the sensitometric valuation of a screen-film combination, that is still the most used, for the standardization, of radiographic images. Thinking about this, were constructed homogeneous phantoms of the chest, skull and pelvis, for the calibration of X-ray beams, with the purpose of obtaining radiographic images of good quality, basing in the routine of a radiodiagnosis service and in the scientific knowledge. Questions were approached about the choice of the suitable equipment, that allow the obtention of k Vp and m As combinations, to produce radiographic images of good quality, and the reproduction of these combinations to any conventional equipment of diagnostic X-rays. Also presented are the comparison of the doses imparted by these combinations and those used in routine of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto's radiodiagnosis service.

    Response strategy is a key for preventing widespread corruption vulnerabilities in the public construction sector. Although several studies have been devoted to this area, the effectiveness of response strategies has seldom been evaluated in China. This study aims to fill this gap by investigating the effectiveness of response strategies for corruption vulnerabilities through a survey in the Chinese public construction sector. Survey data obtained from selected experts involved in the Chinese public construction sector were analyzed by factor analysis and partial least squares-structural equation modeling. Analysis results showed that four response strategies of leadership, rules and regulations, training, and sanctions, only achieved an acceptable level in preventing corruption vulnerabilities in the Chinese public construction sector. This study contributes to knowledge by improving the understanding of the effectiveness of response strategies for corruption vulnerabilities in the public construction sector of developing countries.

    Full Text Available The methodology presented here developed out of work required to convert the hard-copy illustrations submitted to Internet Archaeology for publication of the 1975 excavations at Cricklade. The publication (and digital image preparatory work was funded by English Heritage and was, in part, an experiment designed to explore some of the possibilities presented by digital image publication. Various challenges in how to transform the drawings on permatrace to a digital format were encountered. While a full exploration of the potential of all areas of digital image preparation and publication was not possible, some interesting technical options were evaluated. This short article explains the processes applied in creating the images that were finally incorporated within the publication. It also examines some other avenues regarding the presentation of archaeological drawings that could be explored in both future Internet Archaeology content and other digital publications.

The segmentation process is performed by painting tomographic images and attributing a different color for each organ or tissue. A voxel-based head and neck phantom was built using this new approach. The way as the data are stored allows an increasing in the performance of the radiation transport code. The program that calculates the radiation transport also works with image files. This capability allows image reconstruction showing isodose areas, under several points of view, increasing the information to the user. Virtual X-ray photographs can also be obtained allowing that studies could be accomplished looking for the radiographic techniques optimization assessing, at the same time, the doses in organs and tissues. The accuracy of the program here presented, called MCvoxEL, that implements this new approach, was tested by comparison to results from two modern and well-supported Monte Carlo codes. Dose conversion factors for parallel X-ray exposure were also calculated. (author)

  3. Religion, popular culture and social media: the construction of a religious leader image on Facebook

    Full Text Available Despite the emergence of religions on Internet and the importance of social media, research dedicated to religious leaders’ construction of symbolic image on social media, is hard to find. Starting from the 2013 Applebee’s social media crisis, which was triggered by a pastor, the present study investigates the frames and themes Facebook users employed in order to give meaning to the crisis, attribute responsibility, and more importantly, define the role of a religious leader in daily life. This study shows the existence on social media of an active religious literate public, a public clearly troubled in their religious faith and convictions by the non-Christian behavior of the pastor. This shows that in a post-secular society the religious imaginary is not only a “canopy” inherited and kept because of convenience, but a cultural frame of signification the real and a vector of dialogue in a (online micro and macro public sphere.

    Public health nurses (PHNs) have declined as a proportion of both the nursing and the public health workforces in the past 2 decades. This decline comes as 30 states report public health nursing as the sector most affected in the overall public health shortage. Taken together, these data point to a need for renewed recruitment efforts. However, the current public images of nurses are primarily those of professionals employed in hospital settings. Therefore, this paper describes the development of a marketable image aimed at increasing the visibility and public awareness of PHNs and their work. Such a brand image was seen as a precursor to increasing applications for PHN positions. A multimethod qualitative sequential approach guided the branding endeavor. From the thoughts of public health nursing students, faculty, and practitioners came artists' renditions of four award-winning posters. These posters portray public health nursing-incorporating its image, location of practice, and levels of protection afforded the community. Since their initial unveiling, these posters have been distributed by request throughout the United States and Canada. The overwhelming response serves to underline the previous void of current professional images of public health nursing and the need for brand images to aid with recruitment. © 2010 Wiley Periodicals, Inc.

    Good image is the basis of trust. It is imminent to build good public image as our society and the public pay close attention to the negative information of relevant government departments which directly or indirectly affects the public image of the government departments in recent years. In order to promote the public image of the government regulatory department, it is required for all staff to figure out how to conscientiously fulfill social responsibility, how to respond to and properly handle emergencies, and how to establish and improve a full-time public relations team. Based on nuclear and radiation safety regulatory task, this paper discussed the necessity of government departments to set up the public image, and how to shape the public image of the nuclear and radiation safety regulatory organization.

    Studies on experts' understanding of the public have mainly focused on the views of scientists. We add to the literature on constructions of the public by analyzing the views of decision-makers, professional science communicators and scientists involved in 'space' communication on the public and public participation in policy. Findings show that contextual situations and roles determine the way the public is conceptualised: the public is sophisticated and knowledgeable to participate in space activities/citizen science, but in matters of policy, a gullible image of the public is brought up. Despite the democratic talk on participation, practitioners delimited public involvement in policy in some way or other to protect their own power and decision-making capabilities. This conception of the public competes with the stated aims of scientific and political institutions for public engagement and the substantive value of public participation, leaving a limited role for the public in space policymaking. © The Author(s) 2015.

    In the field of nursing in Switzerland, educations have experienced a fundamental reorganization with the implementation of the new law on Vocational and Professional Education and Training (2004). Among other things, this change affects professional images. To show how the different professional images in the field of nursing are being constructed in the descriptions of professions by graduates after the reshaping of the educations and the occupational field in general. In 110 semi-structured interviews, healthcare assistants and registered nurses (college diploma and Bachelor of Science) in their early careers were asked to explain their professional image. The participant's answers were analysed based on a qualitative content analysis and considering the theoretical background of Berger and Luckmann (1977). The interviews show that professional images emerge on the interaction of societal attributes and individual processes of adoption and revision. Graduates are challenged to adjust stereotypes and to achieve a balance between their own professional image and a missing or inappropriately perceived societal image. There should be further emphasis on the differentiation between the professions and the different educations in the field of nursing in order to achieve a better public perception of the different professions.

    2015-05-01

    In image-based three-dimensional (3-D) reconstruction, one topic of growing importance is how to quickly obtain a 3-D model from a large number of images. The retrieval of the correct and relevant images for the model poses a considerable technological challenge. The "image vocabulary tree" has been proposed as a method to search for similar images. However, a significant drawback of this approach is identified in its low time efficiency and barely satisfactory classification result. The method proposed is inspired by, and improves upon, some recent methods. Specifically, vocabulary quality is considered and multivocabulary trees are designed to improve the classification result. A marked improvement was, indeed, observed in our evaluation of the proposed method. To improve time efficiency, graphics processing unit (GPU) computer unified device architecture parallel computation is applied in the multivocabulary trees. The results of the experiments showed that the GPU was three to four times more efficient than the enumeration matching and CPU methods when the number of images is large. This paper presents a reliable reference method for the rapid construction of a free network to be used for the computing of 3-D information.

    The voxel models representing human anatomy have been developed to calculate dose distribution in human body, while the density and elemental composition are the most important physical properties of voxel model. Usually, when creating the Monte Carlo input files, the average tissue densities recommended in ICRP Publication were used to assign each voxel in the existing voxel models. As each tissue consists of many voxels with different densities, the conventional method of average tissue densities failed to take account of the voxel's discrepancy, and therefore could not represent human anatomy faithfully. To represent human anatomy more faithfully, a method was implemented to assign each voxel, the densities of which were derived from CT number. In order to compare with the traditional method, we constructed two models from the cadaver specimen dataset. A CT-based pelvic voxel model called Pelvis-CT model was constructed, the densities of which were derived from the CT numbers. A color photograph-based pelvic voxel model called Pelvis-Photo model was also constructed, the densities of which were taken from ICRP Publication. The CT images and the color photographs were obtained from the same female cadaver specimen. The Pelvis-CT and Pelvis-Photo models were both ported into Monte Carlo code MCNP to calculate the conversion coefficients from kerma free-in-air to absorbed dose for external monoenergetic photon beams with energies of 0.1, 1 and 10 MeV under anterior-posterior (AP) geometry. The results were compared with those of given in ICRP Publication 74. Differences of up to 50% were observed between conversion coefficients of Pelvis-CT and Pelvis- Photo models, moreover the discrepancies decreased for the photon beams with higher energies. The overall trend of conversion coefficients of the Pelvis-CT model agreed well with that of ICRP Publication 74 data. (author)

  15. CT image construction of a totally deflated lung using deformable model extrapolation

    International Nuclear Information System (INIS)

    Sadeghi Naini, Ali; Pierce, Greg; Lee, Ting-Yim

    2011-01-01

    Purpose: A novel technique is proposed to construct CT image of a totally deflated lung from a free-breathing 4D-CT image sequence acquired preoperatively. Such a constructed CT image is very useful in performing tumor ablative procedures such as lung brachytherapy. Tumor ablative procedures are frequently performed while the lung is totally deflated. Deflating the lung during such procedures renders preoperative images ineffective for targeting the tumor. Furthermore, the problem cannot be solved using intraoperative ultrasound (U.S.) images because U.S. images are very sensitive to small residual amount of air remaining in the deflated lung. One possible solution to address these issues is to register high quality preoperative CT images of the deflated lung with their corresponding low quality intraoperative U.S. images. However, given that such preoperative images correspond to an inflated lung, such CT images need to be processed to construct CT images pertaining to the lung's deflated state. Methods: To obtain the CT images of deflated lung, we present a novel image construction technique using extrapolated deformable registration to predict the deformation the lung undergoes during full deflation. The proposed construction technique involves estimating the lung's air volume in each preoperative image automatically in order to track the respiration phase of each 4D-CT image throughout a respiratory cycle; i.e., the technique does not need any external marker to form a respiratory signal in the process of curve fitting and extrapolation. The extrapolated deformation field is then applied on a preoperative reference image in order to construct the totally deflated lung's CT image. The technique was evaluated experimentally using ex vivo porcine lung. Results: The ex vivo lung experiments led to very encouraging results. In comparison with the CT image of the deflated lung we acquired for the purpose of validation, the constructed CT image was very similar. The

    Full Text Available We address the performance evaluation practices for developing medical image analysis methods, in particular, how to establish and share databases of medical images with verified ground truth and solid evaluation protocols. Such databases support the development of better algorithms, execution of profound method comparisons, and, consequently, technology transfer from research laboratories to clinical practice. For this purpose, we propose a framework consisting of reusable methods and tools for the laborious task of constructing a benchmark database. We provide a software tool for medical image annotation helping to collect class label, spatial span, and expert's confidence on lesions and a method to appropriately combine the manual segmentations from multiple experts. The tool and all necessary functionality for method evaluation are provided as public software packages. As a case study, we utilized the framework and tools to establish the DiaRetDB1 V2.1 database for benchmarking diabetic retinopathy detection algorithms. The database contains a set of retinal images, ground truth based on information from multiple experts, and a baseline algorithm for the detection of retinopathy lesions.

    There are many variables that public clients need to consider in their bidding procedure to enhance efficiency in their procurement for construction services. This paper focusses on the competitive bidding process for public sector procurement of construction services in Singapore. A distinctive feature of the Singapore government competitive bidding process is that full bidding feedback information is released to all competing bidders (and public). The specific objectives are: (i) to examine the degree of competition in the construction markets; and (ii) to examine the bidding performance of competing bidders. Based on a collection of bidding data for a 15-month period, the results show the market environment of the Singapore public sector construction contracting is highly competitive with long bidder lists. In selection of contractors, only 50% of the contracts were awarded to lowest bidders. The results also show that the competing contractors can be broadly classified into three groups based on their bidding performance in terms of number of bidding attempts, bidding success rate and bidding competitiveness. These results provide a useful insight into the bidding competition in the Singapore public sector construction contracting, especially to new market entrants and foreign contractors who want to bid for jobs in Singapore.

    Magnetic resonance is the most powerful, and presents the greatest potential, among diagnostic imaging methods. These features of IMR imaging arise to a grand extent from its multi-parametric condition. IMR images are formed by the contribution of four independent physical tissue parameters: time relaxation constant T1 and T2, proton density and flow. This work presents, analyzes, and explains some of the physical principles of IRM. The purpose of this paper is to offer a trans disciplinary vision of the intricate way from proton to image.

    The mass media has a powerful impact on public attitudes about mental health and psychiatry. The question of identity of psychiatry as a medical profession as well as of the future of psychiatry has been the subject of much controversial discussion. Psychiatry today has the historical opportunity to shape the future of mental health care, medicine and society. It has gained in scientific and professional status by the tremendous increase of knowledge and treatment skills. Psychiatry should build up new transdisciplinary and integrative image of a specialized profession, promote it and make it public. Good public relations are very important for the future of psychiatry.

    Monteiro, Marko

    2015-01-01

    This article offers a reflection on the question of the image in science, thinking about how visual practices contribute towards the construction of knowledge and territories. The growing centrality of the visual in current scientific practices shows the need for reflection that goes beyond the image. The object of discussion will be the scientific images used in the monitoring and visualization of territory. The article looks into the relations between visuality and a number of other factors: the researchers that construct it; the infrastructure involved in the construction; and the institutions and policies that monitor the territory. It is argued that such image-relations do not just visualize but help to construct the territory based on specific forms. Exploring this process makes it possible to develop a more complex understanding of the forms through which sciences and technology help to construct realities.

  3. Spinal fusion-hardware construct: Basic concepts and imaging review

    Nouh, Mohamed Ragab

    2012-01-01

    The interpretation of spinal images fixed with metallic hardware forms an increasing bulk of daily practice in a busy imaging department. Radiologists are required to be familiar with the instrumentation and operative options used in spinal fixation and fusion procedures, especially in his or her institute. This is critical in evaluating the position of implants and potential complications associated with the operative approaches and spinal fixation devices used. Thus, the radiologist can play an important role in patient care and outcome. This review outlines the advantages and disadvantages of commonly used imaging methods and reports on the best yield for each modality and how to overcome the problematic issues associated with the presence of metallic hardware during imaging. Baseline radiographs are essential as they are the baseline point for evaluation of future studies should patients develop symptoms suggesting possible complications. They may justify further imaging workup with computed tomography, magnetic resonance and/or nuclear medicine studies as the evaluation of a patient with a spinal implant involves a multi-modality approach. This review describes imaging features of potential complications associated with spinal fusion surgery as well as the instrumentation used. This basic knowledge aims to help radiologists approach everyday practice in clinical imaging. PMID:22761979

    Su, W G; Su, F Z; Zhou, C H

    2014-01-01

    Nowadays, most remote sensing image classification uses single satellite remote sensing data, so the number of bands and band spectral width is consistent. In addition, observed phenomenon such as land cover have the same spectral signature, which causes the classification accuracy to decrease as different data have unique characteristic. Therefore, this paper analyzes different optical remote sensing satellites, comparing the spectral differences and proposes the ideas and methods to build a virtual satellite. This article illustrates the research on the TM, HJ-1 and MODIS data. We obtained the virtual band X 0 through these satellites' bands combined it with the 4 bands of a TM image to build a virtual satellite with five bands. Based on this, we used these data for image classification. The experimental results showed that the virtual satellite classification results of building land and water information were superior to the HJ-1 and TM data respectively

    Directory of Open Access Journals (Sweden)

    Catherine Happer

    2013-12-01

    Full Text Available The media play a central role in informing the public about what happens in the world, particularly in those areas in which audiences do not possess direct knowledge or experience. This article examines the impact the media has in the construction of public belief and attitudes and its relationship to social change. Drawing on findings from a range of empirical studies, we look at the impact of media coverage in areas such as disability, climate change and economic development. Findings across these areas show the way in which the media shape public debate in terms of setting agendas and focusing public interest on particular subjects. For example, in our work on disability we showed the relationship between negative media coverage of people on disability benefit and a hardening of attitudes towards them. Further, we found that the media also severely limit the information with which audiences understand these issues and that alternative solutions to political problems are effectively removed from public debate. We found other evidence of the way in which media coverage can operate to limit understanding of possibilities of social change. In our study of news reporting of climate change, we traced the way that the media have constructed uncertainty around the issue and how this has led to disengagement in relation to possible changes in personal behaviours. Finally, we discuss the implications for communications and policy and how both the traditional and new media might help in the development of better informed public debate.

    Over recent years, the issue of corruption in the public construction sector has attracted increasing attention from both practitioners and researchers worldwide. However, limited efforts are available for investigating the underlying factors of corruption in this sector. Thus, this study attempted to bridge this knowledge gap by exploring the underlying factors of corruption in the public construction sector of China. To achieve this goal, a total of 14 structured interviews were first carried out, and a questionnaire survey was then administered to 188 professionals in China. Two iterations of multivariate analysis approaches, namely, stepwise multiple regression analysis and partial least squares structural equation modeling were successively utilized to analyze the collected data. In addition, a case study was also conducted to triangulate the findings obtained from the statistical analysis. The results generated from these three research methods achieve the same conclusion: the most influential underlying factor leading to corruption was immorality, followed by opacity, unfairness, procedural violation, and contractual violation. This study has contributed to the body of knowledge by exploring the properties of corruption in the public construction sector. The findings from this study are also valuable to the construction authorities as they can assist in developing more effective anti-corruption strategies.

    In June 2010, Basic Energy Plan was approved in a Cabinet meeting. It says that Japan aims to construct more than 14 atomic power plants by 2030. Today, there are 12 plans of construction of atomic power plant, but it is hard to say that their plans easily come off. That's because public acceptance of atomic power plant is low in Japan, for example local residents wage opposition campaigns. This study conducts a survey in the form of a questionnaire and analyzes it by Analytical Hierarchical Process (AHP). Analytic Hierarchy Process is a structured technique for dealing with complex decisions. A questionnaire using AHP is very easy to answer and analyze. This survey was conducted in 2 areas. First area is Hohoku-cho, Yamaguchi Pref. that had a plan of construction of atomic power plant and the plan was demolished by opposition campaigns. Second area is Kaminoseki-cho, Yamaguchi Pref. that has a plan of construction of atomic power plant now and the plan is working order. Public acceptance can be calculated from survey data of 2 areas, and it helps to understand why first area disapproved a plan of atomic power plant and second area approves it. We consider a model to analyze public acceptance. (author)

    Cloud computing promises medical imaging services offering large storage and computing capabilities for limited costs. In this data outsourcing framework, one of the greatest issues to deal with is data security. To do so, we propose to secure a public cloud platform devoted to medical image sharing by defining and deploying a security policy so as to control various security mechanisms. This policy stands on a risk assessment we conducted so as to identify security objectives with a special interest for digital content protection. These objectives are addressed by means of different security mechanisms like access and usage control policy, partial-encryption and watermarking.

In order to compare with the traditional method, we have constructed two models from a same cadaver specimen date set. A CT-based pelvic voxel model called Pelvis-CT model, was constructed, the densities of which were derived from the CT numbers. A color photograph-based pelvic voxel model called Pelvis-Photo model, was also constructed, the densities of which were taken from ICRP Publication. The CT images and color photographs were obtained from the same female cadaver specimen. The Pelvis-CT and Pelvis-Photo models were ported into Monte Carlo code MCNP to calculate the conversion coefficients from kerma free-in-air to absorbed dose for external monoenergetic photon beams with energies of 0.1, 1 and 10 MeV under anterior-posterior (AP) geometries. The results were compared with those of given in ICRP74. Differences of up to 50% were observed between conversion coefficients of Pelvis-CT and Pelvis-Photo models, moreover the discrepancies decreased for the photon beams with higher energies. The overall trend of conversion coefficients of the Pelvis-CT model were agreed well with that of ICRP74 data. (author)

    With advances in technology, a large part of our cultural heritage is becoming digitally available. In particular, in the field of historical document image analysis, there is now a growing need for indexing and data mining tools, thus allowing us to spot and retrieve the occurrences of an object of interest, called a pattern, in a large database of document images. Patterns may present some variability in terms of color, shape, or context, making the spotting of patterns a challenging task. Pattern spotting is a relatively new field of research, still hampered by the lack of available annotated resources. We present a new publicly available dataset named DocExplore dedicated to spotting patterns in historical document images. The dataset contains 1500 images and 1464 queries, and allows the evaluation of two tasks: image retrieval and pattern localization. A standardized benchmark protocol along with ad hoc metrics is provided for a fair comparison of the submitted approaches. We also provide some first results obtained with our baseline system on this new dataset, which show that there is room for improvement and that should encourage researchers of the document image analysis community to design new systems and submit improved results.

    Full Text Available In the search for high efficiency in root studies, computational systems have been developed to analyze digital images. ImageJ and Safira are public-domain systems that may be used for image analysis of washed roots. However, differences in root properties measured using ImageJ and Safira are supposed. This study compared values of root length and surface area obtained with public-domain systems with values obtained by a reference method. Root samples were collected in a banana plantation in an area of a shallower Typic Carbonatic Haplic Cambisol (CXk, and an area of a deeper Typic Haplic Ta Eutrophic Cambisol (CXve, at six depths in five replications. Root images were digitized and the systems ImageJ and Safira used to determine root length and surface area. The line-intersect method modified by Tennant was used as reference; values of root length and surface area measured with the different systems were analyzed by Pearson's correlation coefficient and compared by the confidence interval and t-test. Both systems ImageJ and Safira had positive correlation coefficients with the reference method for root length and surface area data in CXk and CXve. The correlation coefficient ranged from 0.54 to 0.80, with lowest value observed for ImageJ in the measurement of surface area of roots sampled in CXve. The IC (95 % revealed that root length measurements with Safira did not differ from that with the reference method in CXk (-77.3 to 244.0 mm. Regarding surface area measurements, Safira did not differ from the reference method for samples collected in CXk (-530.6 to 565.8 mm² as well as in CXve (-4231 to 612.1 mm². However, measurements with ImageJ were different from those obtained by the reference method, underestimating length and surface area in samples collected in CXk and CXve. Both ImageJ and Safira allow an identification of increases or decreases in root length and surface area. However, Safira results for root length and surface area are

  20. Individual Travel Behavior Modeling of Public Transport Passenger Based on Graph Construction

    2018-01-01

    Full Text Available This paper presents a novel method for mining the individual travel behavior regularity of different public transport passengers through constructing travel behavior graph based model. The individual travel behavior graph is developed to represent spatial positions, time distributions, and travel routes and further forecasts the public transport passenger’s behavior choice. The proposed travel behavior graph is composed of macronodes, arcs, and transfer probability. Each macronode corresponds to a travel association map and represents a travel behavior. A travel association map also contains its own nodes. The nodes of a travel association map are created when the processed travel chain data shows significant change. Thus, each node of three layers represents a significant change of spatial travel positions, travel time, and routes, respectively. Since a travel association map represents a travel behavior, the graph can be considered a sequence of travel behaviors. Through integrating travel association map and calculating the probabilities of the arcs, it is possible to construct a unique travel behavior graph for each passenger. The data used in this study are multimode data matched by certain rules based on the data of public transport smart card transactions and network features. The case study results show that graph based method to model the individual travel behavior of public transport passengers is effective and feasible. Travel behavior graphs support customized public transport travel characteristics analysis and demand prediction.

    Collagen fibers play an important role in the biomechanics of the blood vessel wall. The objective of this study was to determine the 3D microstructure of collagen fibers in the media and adventitia of coronary arteries. We present a novel optimal angle consistence algorithm to reform image slices in the visualization and analysis of 3D collagen images. 3D geometry was reconstructed from resliced image space where the 3D skeleton was extracted as the primary feature for accurate reconstruction of geometrical parameters. Collagen fibers (range 80-200) were reconstructed from the porcine coronary artery wall for the measurement of various morphological parameters. Collagen waviness and diameters were 1.37 ± 0.19 and 2.61 ± 0.89 μm, respectively. The biaxial distributions of orientation had two different peaks at 110.7 ± 25.2° and 18.4 ± 19.3°. Results for width, waviness, and orientation were found to be in good agreement with manual measurements. In addition to accurately measuring 2D features more efficiently than the manual approach, the present method produced 3D features that could not be measured in the 2D manual approach. These additional parameters included the tilt angle (5.10 ± 2.95°) and cross-sectional area (CSA; 5.98 ± 3.79 μm2) of collagen fibers. These 3D collagen reconstructions provide accurate and reliable microstructure for biomechanical modeling of vessel wall mechanics.

    One of the first tasks in starting a construction project is to estimate the total cost of building a project. In Indonesia there are several standards that are used to calculate the cost estimation of a project. One of the standards used in based on the Ministerial Regulation of Public Work No. 11/2013. However in a construction project, contractor often has their own cost estimation based on their own calculation. This research aimed to compare the construction project total cost using calculation based on the Ministerial Regulation of Public Work No. 11/2013 against the contractor’s calculation. Two projects were used as case study to compare the results. The projects were a 4 storey building located in Pantai Indah Kapuk area (West Jakarta) and a warehouse located in Sentul (West Java) which was built by 2 different contractors. The cost estimation from both contractors’ calculation were compared to the one based on the Ministerial Regulation of Public Work No. 11/2013. It is found that there were differences between the two calculation around 1.80 % - 3.03% in total cost, in which the cost estimation based on Ministerial Regulation was higher than the contractors’ calculations.

    NOAA's National Centers for Environmental Information (NCEI) manages the most comprehensive, accessible, and trusted source of environmental data and information in the US. It archives data from the depths of the ocean to the surface of the sun and from million-year-old sediment records to near real-time satellite observations. NCEI has a wealth of knowledge and experience in long-term data preservation with the goal of supporting today's scientists as well as future generations. In order to reduce fragmentation of data, publications, images, and documentation, and to improve preservation, curation, and stewardship of data, NCEI continues to partner with the NOAA Central Library (NCL). NCEI and NCL have long-established linkages between data metadata, published reports, and data or archival information packages (AIP). We also have analog AIPs that are stored and maintained in the NCL collection and discoverable in both NCEI and NCL collections via the AIP identifier. We are currently working with NCL to establish a workflow for submitting reports to their Institutional Repository and linking the data and report via digital object identifiers. We hope to establish linkages between images of physical samples and the NCL Photo Collection management infrastructure in the future. This presentation will detail how NCEI engages with the NCL in order to fully integrate documentation, images, publications, and data in preservation practices and improve the discovery and usability of NOAA's billion dollar investment in environmental data and information.

  11. Public acceptance of constructing coastal/inland nuclear power plants in post-Fukushima China

    2017-01-01

    Risk perception and public involvement have become more and more important in post-Fukushima accident era. A survey had been carried out about public acceptance of constructing coastal/inland Nuclear Power Plants (NPPs) in China. We examined impact factors of public acceptance of nuclear energy and also carried out a comparison between China and OECD. The study revealed that the public still took relatively optimistic attitude although there was a slight decrease just after Fukushima and the public's confidence recovered four years later. The ratio of inland NPPs opponents reached to quite a high level and “not-in-my-back-yard” still reflected an obvious syndrome. We also found public acceptance is mainly affected by benefit and, to a lesser extent, by knowledge, education and age. Moreover, the study suggested government is still a creditable information resource due to its authority but most of respondents felt little or no well-informed about nuclear safety, which means a significant communication gap exists between government and the public. As China is the most ambitious country to develop nuclear energy, it is proposed to introduce a transparent and open system of third-party evaluation, which mainly consists of scientists and non-profit research institutions, to ensure the healthy and sustainable development of nuclear energy. - Highlights: • The public are more optimistic about nuclear energy in China than in OECD. • The ratio of inland nuclear power plants opponents reaches to quite a high level. • Government is still a creditable information resource due to its authority. • Third-party evaluation is proposed to intervene in nuclear safety supervision.

    2009-09-01

    The Societe d'Energie Riviere Sheldrake Inc. has proposed the construction of a hydroelectric facility on the Sheldrake River at Riviere-au-Tonnerre in the regional municipality of Minganie in Quebec. The project involves the construction of a headrace canal, intake, tunnel, powerhouse, access roads, electrical transmission line, spillway, weir and a bridge over the Sheldrake River. The proposed development was subject to an environmental evaluation process and public consultation. Quebec's environmental public hearing board held a public hearing on the draft development of the project to hear the concerns and views of the public and stakeholders. The hearing focused on a number issues, such as reasons for the project, its location and socio-economic impacts. The cumulative environmental effects of the project were also examined. The primary concerns were the economic repercussions of the project and its effect on tourism and fish, including salmon. The Board determined that the project would create jobs in a region affected by unemployment and the decay of its municipalities and that it would stimulate the local and regional economy. However, the Board determined that changes to the project are required to minimize impacts on the natural environment. The project proponent must monitor instream flows to ensure that fish passage facilities meet regulations. In addition, since the proposed project crosses 3 bogs, the developer must compensate for lost wetlands. A 10-year follow-up is required to assess the recovery of these environments. The developer must also maintain the aesthetic quality of the Courbe du Sault Falls in order to maintain the eco-tourism in the region. refs., figs.

    Full Text Available Impairments of retrospective memory and cases of retrograde amnesia are often seen in clinical settings. A measure of the proportion of memories retained over a specified time can be useful in clinical situations and public events questionnaires may be valuable in this respect. However, consistency of retention of public events memory has rarely been studied in the same participants. In addition, when used in a research context, public events questionnaires require updating to ensure questions are of equivalent age with respect to when the test is taken. This paper describes an approach to constructing and updating a Public Events Questionnaire (PEQ for use with a sample that is recruited and followed-up over a long time-period. Internal consistency, parallel-form reliability, test-retest reliability and secondary validity analyses were examined for three versions of the PEQ that were updated every six months. Versions 2 and 3 of the questionnaire were reliable across and within versions and for recall and recognition. Change over time was comparable across each version of the PEQ. These results show that PEQs can be regularly updated in a standardised fashion to allow use throughout studies with long recruitment periods.

    2015-01-01

    Studies on experts’ understanding of the public have mainly focused on the views of scientists. We add to the literature on constructions of the public by analyzing the views of decision-makers, professional science communicators and scientists involved in ‘space’ communication on the public and public participation in policy. Findings show that contextual situations and roles determine the way the public is conceptualised: the public is sophisticated and knowledgeable to participate in space activities/citizen science, but in matters of policy, a gullible image of the public is brought up. Despite the democratic talk on participation, practitioners delimited public involvement in policy in some way or other to protect their own power and decision-making capabilities. This conception of the public competes with the stated aims of scientific and political institutions for public engagement and the substantive value of public participation, leaving a limited role for the public in space policymaking.

    1989-01-01

    A volumetric reconstruction of a three-dimensional (3-D) object has been at the forefront of exploration in medical applications for a long time. To achieve this goal, a prototype system for an image intensifier(II)-based volume computed tomography (CT) imager has been constructed. This research has been concerned with constructing and evaluating such a prototype system by phantom studies. The prototype system consists of a fixed x-ray tube, a specially designed aluminum filter that will reduce the dynamic range of projection data, an antiscatter grid, a conventional image intensifier optically coupled to a charge-coupled device (CCC) camera, a computer controlled turntable on which phantoms are placed, a digital computer including an A/D converter and a graphic station that displays the reconstructed images. In this study, three different phantoms were used: a vascular phantom, a resolution phantom and a Humanoid reg-sign chest phantom. The direct 3-D reconstruction from the projections was performed using a cone beam algorithm and vascular reconstruction algorithms. The image performance of the system for the direct 3-D reconstruction was evaluated. The spatial resolution limits of the system were estimated through observing the reconstructed images of the resolution phantom. By observing the images reconstructed from the projections, it can be determined that the image performance of the prototype system for a direct 3-D reconstruction is reasonably good and that the vascular reconstruction algorithms work very well. The results also indicate that the 3-D reconstructions obtained with the 11-based volume CT imager have nearly equally good resolution in x, y and z directions and are superior to a conventional CT in the resolution of the z direction

    2017-10-01

    Growing demand to increase the investment volume in modernization and development projects for transport infrastructure define the urgency of the current study. The amount of private sector investments in the field is insufficient to implement the projects for road construction due to their significant capital intensity and long payoff period. The implementation of social significant infrastructure projects on the principles of public-private partnership is one of the key strategic directions of growth for transport facilities. The authors come up with a concept and methodology for modeling the investment and innovation activity in the transport facility construction. Furthermore, there is developed a model to find the balance between public and private sector investments in implementing construction projects for transport infrastructure with involvement of PPP (further - public-private partnership). The suggested concepts aim to improve the efficiency rate of the investment and innovation activity in the field of transport facility construction on the basis of public and private sectors collaboration.

  6. Patch-based image segmentation of satellite imagery using minimum spanning tree construction

    Energy Technology Data Exchange (ETDEWEB)

    Skurikhin, Alexei N [Los Alamos National Laboratory

    2010-01-01

    We present a method for hierarchical image segmentation and feature extraction. This method builds upon the combination of the detection of image spectral discontinuities using Canny edge detection and the image Laplacian, followed by the construction of a hierarchy of segmented images of successively reduced levels of details. These images are represented as sets of polygonized pixel patches (polygons) attributed with spectral and structural characteristics. This hierarchy forms the basis for object-oriented image analysis. To build fine level-of-detail representation of the original image, seed partitions (polygons) are built upon a triangular mesh composed of irregular sized triangles, whose spatial arrangement is adapted to the image content. This is achieved by building the triangular mesh on the top of the detected spectral discontinuities that form a network of constraints for the Delaunay triangulation. A polygonized image is represented as a spatial network in the form of a graph with vertices which correspond to the polygonal partitions and graph edges reflecting pairwise partitions relations. Image graph partitioning is based on the iterative graph oontraction using Boruvka's Minimum Spanning Tree algorithm. An important characteristic of the approach is that the agglomeration of partitions is constrained by the detected spectral discontinuities; thus the shapes of agglomerated partitions are more likely to correspond to the outlines of real-world objects.

    Full Text Available This article argues that much of the postmodern discourse on the Muslim woman and her veil is symptomatic of what I call the “essentialist paradigm”. The world is seen through the prism of a group’s religious/cultural identity and eventually constructs a Muslim identity – and with it an image of the Muslim Woman. The image of the oppressed veiled Muslim Woman and the treatment of a piece of cloth as synonymous with her whole identity and being are products of this paradigm of thought. Using an interdisciplinary approach that combines discourse analysis and a case study of the construction of the British Muslim community, this article argues that the essentialist paradigm ignores the context of its subject matter with all its accompanying power structures, political and social factors, and the roles played by both the state and fundamentalist Islam in constructing a Muslim identity and with it the Muslim Woman and her dress code.

  9. The International Criminal Court and the construction of International Public Order

    Full Text Available Envisioning an international public order means envisioning an order sustained by a legal and institutional framework that ensures effective collective action with a view to defending fundamental values of the international community and to solving common global problems, in line with the universalist vision of international law. Envisioning the construction of an international public order means considering that this framework, which embraces and promotes the respect for human rights focused particularly on human dignity, is consolidating and evolving based on the International Criminal Court (ICC. The establishment of the ICC added an international punitive perennial facet to international humanitarian law and international human rights law and linked justice to peace, to security and to the well-being of the world, reaffirming the principles and objectives of the Charter of the United Nations (UN. Nevertheless, the affirmation process of an international criminal justice by punishing those responsible for the most serious crimes of concern to the international community as a whole, faces numerous obstacles of political and normative character. This article identifies the central merits of the Rome Statute and ICC’s practice and indicates its limitations caused by underlying legal-political tensions and interpretive questions relating to the crime of aggression and crimes against humanity. Finally, the article argues for the indispensability of rethinking the jurisdiction of the ICC, defending the categorization of terrorism as an international crime, and of articulating its mission with the "responsibility to protect", which may contribute to the consolidation of the ICC and of international criminal law and reinforce its role in the construction of an effective international public order.

    2015-04-01

    Full Text Available This paper discusses the formation process of CSR images from a customer perspective. It analyses the influence of company-CSR coherence, motivational attribution and corporate credibility in the way customers evaluate CSR images in the banking industry. It also describes the impact of customer gender, age and educational level on the formation of CSR images. Results show that CSR images are based on customer perceptions of the company-CSR coherence, the attribution of altruistic motivations and corporate credibility when developing CSR initiatives. The findings also demonstrate that gender, age and educational level do not allow identifying differences in the way customers construct CSR images. Thus, they are not useful in segmenting customers for the design of better CSR and communication strategies.

    Neuroradiology has become indispensable in detecting the pathophysiology in syringomyelia. Constructive interference in steady-state (CISS) magnetic resonance (MR) imaging can provide superior contrast at the sub-arachnoid tissue borders. As this region is critical in preoperative evaluation, the authors hypothesized that CISS imaging would provide superior assessment of syrinx pathology and surgical planning. Based on records collected from a database of 130 patients with syringomyelia treated at the authors' institution, 59 patients were prospectively evaluated with complete neuroradiological examinations. In addition to routine acquisitions with FLAIR, T1- and T2-weighted, and contrast-enhanced MR imaging series, the authors obtained sagittal cardiac-gated sequences to visualize cerebrospinal fluid (CSF) pulsations and axial 3D CISS MR sequences to detect focal arachnoid webs. Statistical qualitative and quantitative evaluations of spinal cord/CSF contrast, spinal cord/CSF delineation, motion artifacts, and artifacts induced by pulsatile CSF flow were performed. The 3D CISS MR sequences demonstrated a contrast-to-noise ratio significantly better than any other routine imaging sequence (p CSF flow voids. Constructive interference in steady-state MR imaging enables the neurosurgeon to accurately identify cases requiring decompression for obstructed CSF. Motion artifacts can be eliminated with technical variations.

    Xiaozhou Fan

    Full Text Available To facilitate prostate cancer imaging using targeted molecules, we constructed ultrasonic nanobubbles coupled with specific anti-PSMA (prostate specific membrane antigen nanobodies, and evaluated their in vitro binding capacity and in vivo imaging efficacy. The "targeted" nanobubbles, which were constructed via a biotin-streptavidin system, had an average diameter of 487.60 ± 33.55 nm and carried the anti-PSMA nanobody as demonstrated by immunofluorescence. Microscopy revealed targeted binding of nanobubbles in vitro to PSMA-positive cells. Additionally, ultrasonography indicators of nanobubble imaging (including arrival time, peak time, peak intensity and enhanced duration were evaluated for the ultrasound imaging in three kinds of animal xenografts (LNCaP, C4-2 and MKN45, and showed that these four indicators of targeted nanobubbles exhibited significant differences from blank nanobubbles. Therefore, this study not only presents a novel approach to target prostate cancer ultrasonography, but also provides the basis and methods for constructing small-sized and high-efficient targeted ultrasound nanobubbles.

    The digital signature is a key technology in the forthcoming Internet society for electronic healthcare as well as for electronic commerce. Efficient exchanges of authorized information with a digital signature in healthcare information networks require a construction of a public key infrastructure (PKI). In order to introduce a PKI to healthcare information networks in Japan, we proposed a development of a user authentication system based on a PKI for user management, user authentication and privilege management of healthcare information systems. In this paper, we describe the design of the user authentication system and its implementation. The user authentication system provides a certification authority service and a privilege management service while it is comprised of a user authentication client and user authentication serves. It is designed on a basis of an X.509 PKI and is implemented with using OpenSSL and OpenLDAP. It was incorporated into the financial information management system for the national university hospitals and has been successfully working for about one year. The hospitals plan to use it as a user authentication method for their whole healthcare information systems. One implementation of the system is free to the national university hospitals with permission of the Japanese Ministry of Education, Culture, Sports, Science and Technology. Another implementation is open to the other healthcare institutes by support of the Medical Information System Development Center (MEDIS-DC). We are moving forward to a nation-wide construction of a PKI for healthcare information networks based on it.

    Full Text Available This paper addresses the role of imagery and tourism experiences (TEs in the construction of tourism destination image (TDI. It highlights the importance of the construct imagery at all stages of consumption, because of the intangibility that characterizes tourism and services in general. This aspect gains importance since it is impossible for tourists to experience the desired holidays prior to visitation, leading the way for imagery to become an essential element to inspire and to influence them during the decision-making process, and consumption before, during and after the experience. A conceptual model resulting from the literature review and the potential theoretical contribution of the model are discussed.

    Full Text Available We developed an algorithm to determine a combination of satellite images according to observation extent and image quality. The algorithm was for testing necessity for completing coverage of the search extent. The tests excluded unnecessary images with low quality and preserve necessary images with good quality. The search conditions of the satellite images could be extended, indicating the catalogue could be constructed with specified periods required for time series analysis. We applied the method to a database of metadata of ASTER satellite images archived in GEO Grid of National Institute of Advanced Industrial Science and Technology (AIST, Japan. As indexes of populated places with geographical coordinates, we used a database of 3372 populated place of more than 0.1 million populations retrieved from GRUMP Settlement Points, a global gazetteer of cities, which has geographical names of populated places associated with geographical coordinates and population data. From the coordinates of populated places, 3372 extents were generated with radiuses of 30 km, a half of swath of ASTER satellite images. By merging extents overlapping each other, they were assembled into 2214 extents. As a result, we acquired combinations of good quality for 1244 extents, those of low quality for 96 extents, incomplete combinations for 611 extents. Further improvements would be expected by introducing pixel-based cloud assessment and pixel value correction over seasonal variations.

    Image processing is an important quantitative technique for neuroscience researchers, but difficult for those who lack experience in the field. In this paper we present a web-based platform that allows an expert to create a brain image processing pipeline, enabling execution of that pipeline even by those biomedical researchers with limited image processing knowledge. These tools are implemented as a plugin for Midas, an open-source toolkit for creating web based scientific data storage and processing platforms. Using this plugin, an image processing expert can construct a pipeline, create a web-based User Interface, manage jobs, and visualize intermediate results. Pipelines are executed on a grid computing platform using BatchMake and HTCondor. This represents a new capability for biomedical researchers and offers an innovative platform for scientific collaboration. Current tools work well, but can be inaccessible for those lacking image processing expertise. Using this plugin, researchers in collaboration with image processing experts can create workflows with reasonable default settings and streamlined user interfaces, and data can be processed easily from a lab environment without the need for a powerful desktop computer. This platform allows simplified troubleshooting, centralized maintenance, and easy data sharing with collaborators. These capabilities enable reproducible science by sharing datasets and processing pipelines between collaborators. In this paper, we present a description of this innovative Midas plugin, along with results obtained from building and executing several ITK based image processing workflows for diffusion weighted MRI (DW MRI) of rodent brain images, as well as recommendations for building automated image processing pipelines. Although the particular image processing pipelines developed were focused on rodent brain MRI, the presented plugin can be used to support any executable or script-based pipeline.

    Tomographic models are currently the most complete, developed and realistic models of the human anatomy. They have been used to estimate organ doses for diagnostic radiation examination and radiotherapy treatment planning, and radiation protection. The quality of original anatomic images is a key factor to build a quality tomographic model. Computed tomography (CT) and magnetic resonance imaging (MRI) scan, from which most of current tomographic models are constructed, have their inherent shortcomings. In this study, a tomographic model of Korean adult male head was constructed by using serially sectioned photographs of cadaver. The cadaver was embedded, frozen, serially sectioned and photographed by high resolution digital camera at 0.2 mm interval. The contours of organs and tissues in photographs were segmented by several trained anatomists. The 120 segmented images of head at 2mm interval were converted into binary files and ported into Monte Carlo code to perform an example calculation of organ dose. Whole body tomographic model will be constructed by using the procedure developed in this study

    Human hydatid disease (cystic echinococcosis, CE) is a chronic parasitic infection caused by the larval stage of the cestode Echinococcus granulosus. As the disease mainly affects the liver, approximately 70% of all identified CE cases are detected in this organ. Optical molecular imaging (OMI), a noninvasive imaging technique, has never been used in vivo with the specific molecular markers of CE. Thus, we aimed to construct an in vivo fluorescent imaging mouse model of CE to locate and quantify the presence of the parasites within the liver noninvasively. Drug-treated protoscolices were monitored after marking by JC-1 dye in in vitro and in vivo studies. This work describes for the first time the successful construction of an in vivo model of E. granulosus in a small living experimental animal to achieve dynamic monitoring and observation of multiple time points of the infection course. Using this model, we quantified and analyzed labeled protoscolices based on the intensities of their red and green fluorescence. Interestingly, the ratio of red to green fluorescence intensity not only revealed the location of protoscolices but also determined the viability of the parasites in vivo and in vivo tests. The noninvasive imaging model proposed in this work will be further studied for long-term detection and observation and may potentially be widely utilized in susceptibility testing and therapeutic effect evaluation.

    The purpose of this study was to use three-dimensional (3-D) printing techniques to construct liver and brain phantoms having realistic pathologies, anatomic structures, and heterogeneous backgrounds. Patient liver and head computed tomography (CT) images were segmented into tissue, vessels, liver lesion, white and gray matter, and cerebrospinal fluid (CSF). Stereolithography files of each object were created and imported into a commercial 3-D printer. Printing materials were assigned to each object after test scans, which showed that the printing materials had CT numbers ranging from 70 to 121 HU at 120 kV. Printed phantoms were scanned on a CT scanner and images were evaluated. CT images of the liver phantom had measured CT numbers of 77.8 and 96.6 HU for the lesion and background, and 137.5 to 428.4 HU for the vessels channels, which were filled with iodine solutions. The difference in CT numbers between lesions and background (18.8 HU) was representative of the low-contrast values needed for optimization tasks. The liver phantom background was evaluated with Haralick features and showed similar texture between patient and phantom images. CT images of the brain phantom had CT numbers of 125, 134, and 108 HU for white matter, gray matter, and CSF, respectively. The CT number differences were similar to those in patient images.

    Construction site monitoring is an essential task for keeping track of the ongoing construction work and providing up-to-date information for a Building Information Model (BIM). The BIM contains the as-planned states (geometry, schedule, costs, ...) of a construction project. For updating, the as-built state has to be acquired repeatedly and compared to the as-planned state. In the approach presented here, a 3D representation of the as-built state is calculated from photogrammetric images using multi-view stereo reconstruction. On construction sites one has to cope with several difficulties like security aspects, limited accessibility, occlusions or construction activity. Different acquisition strategies and techniques, namely (i) terrestrial acquisition with a hand-held camera, (ii) aerial acquisition using a Unmanned Aerial Vehicle (UAV) and (iii) acquisition using a fixed stereo camera pair at the boom of the crane, are tested on three test sites. They are assessed considering the special needs for the monitoring tasks and limitations on construction sites. The three scenarios are evaluated based on the ability of automation, the required effort for acquisition, the necessary equipment and its maintaining, disturbance of the construction works, and on the accuracy and completeness of the resulting point clouds. Based on the experiences during the test cases the following conclusions can be drawn: Terrestrial acquisition has the lowest requirements on the device setup but lacks on automation and coverage. The crane camera shows the lowest flexibility but the highest grade of automation. The UAV approach can provide the best coverage by combining nadir and oblique views, but can be limited by obstacles and security aspects. The accuracy of the point clouds is evaluated based on plane fitting of selected building parts. The RMS errors of the fitted parts range from 1 to a few cm for the UAV and the hand-held scenario. First results show that the crane camera

    Monitoring urban changes is important for city management, urban planning, updating of cadastral map, etc. In contrast to conventional field surveys, which are usually expensive and slow, remote sensing techniques are fast and cost-effective alternatives. Spaceborne synthetic aperture radar (SAR) sensors provide radar images captured rapidly over vast areas at fine spatiotemporal resolution. In addition, the active microwave sensors are capable of day-and-night vision and independent of weather conditions. These advantages make multi-temporal SAR images suitable for scene monitoring. Persistent scatterer interferometry (PSI) detects and analyses PS points, which are characterized by strong, stable, and coherent radar signals throughout a SAR image sequence and can be regarded as substructures of buildings in built-up cities. Attributes of PS points, for example, deformation velocities, are derived and used for further analysis. Based on PSI, a 4D change detection technique has been developed to detect disappearance and emergence of PS points (3D) at specific times (1D). In this paper, we apply this 4D technique to the centre of Berlin, Germany, to investigate its feasibility and application for construction monitoring. The aims of the three case studies are to monitor construction progress, business districts, and single buildings, respectively. The disappearing and emerging substructures of the buildings are successfully recognized along with their occurrence times. The changed substructures are then clustered into single construction segments based on DBSCAN clustering and α-shape outlining for object-based analysis. Compared with the ground truth, these spatiotemporal results have proven able to provide more detailed information for construction monitoring.

    The purpose of this study is to use 3D printing techniques to construct a realistic liver phantom with heterogeneous background and anatomic structures from patient CT images, and to use the phantom to assess image quality with filtered backprojection and iterative reconstruction algorithms. Patient CT images were segmented into liver tissues, contrast-enhanced vessels, and liver lesions using commercial software, based on which stereolithography (STL) files were created and sent to a commercial 3D printer. A 3D liver phantom was printed after assigning different printing materials to each object to simulate appropriate attenuation of each segmented object. As high opacity materials are not available for the printer, we printed hollow vessels and filled them with iodine solutions of adjusted concentration to represent enhance levels in contrast-enhanced liver scans. The printed phantom was then placed in a 35×26 cm oblong-shaped water phantom and scanned repeatedly at 4 dose levels. Images were reconstructed using standard filtered backprojection and an iterative reconstruction algorithm with 3 different strength settings. Heterogeneous liver background were observed from the CT images and the difference in CT numbers between lesions and background were representative for low contrast lesions in liver CT studies. CT numbers in vessels filled with iodine solutions represented the enhancement of liver arteries and veins. Images were run through a Channelized Hotelling model observer with Garbor channels and ROC analysis was performed. The AUC values showed performance improvement using the iterative reconstruction algorithm and the amount of improvement increased with strength setting.

    The public image of the nurse constitutes an important factor for recruitment into the profession, retention, and also for work satisfaction. The aim of this qualitative study was to disclose the way nurses internalize their professional public image and professional worth, as well as nurses' feelings about that image. Findings showed that although nurses have made a tremendous effort to improve the public image of their profession, negative nursing stereotypes still persist. Therefore, nurses have to actively participate in policy making and enhance their educational and cultural profile through the media.

    Introduction: Assessment of image interpretation competency is commonly undertaken through review of a defined image test bank. Content of these image banks has been criticised for the high percentage of abnormal examinations which contrasts with lower reported incidences of abnormal radiographs in clinical practice. As a result, questions have been raised regarding the influence of prevalence bias on the accuracy of interpretive decision making. This article describes a new and novel approach to the design of musculoskeletal image test banks. Methods: Three manufactured image banks were compiled following a standard academic menu in keeping with previous studies. Three further image test banks were constructed to reflect local clinical workload within a single NHS Trust. Eighteen radiographers, blinded to the method of test bank composition, were randomly assigned 2 test banks to review (1 manufactured, 1 clinical workload). Comparison of interpretive accuracy was undertaken. Results: Inter-rater agreement was moderate to good for all image banks (manufactured: range k = 0.45–0.68; clinical workload: k = 0.49–0.62). A significant difference in mean radiographer sensitivity was noted between test bank designs (manufactured 87.1%; clinical workload 78.5%; p = 0.040, 95% CI = 0.4–16.8; t = 2.223). Relative parity in radiographer specificity and overall accuracy was observed. Conclusion: This study confirms the findings of previous research that high abnormality prevalence image banks over-estimate the ability of observers to identify abnormalities. Assessment of interpretive competency using an image bank that reflects local clinical practice is a better approach to accurately establish interpretive competency and the learning development needs of individual practitioners. - Highlights: • High prevalence image test banks over-estimate the ability of observers. • Clinical workload test banks may better reflect image interpretation competency.

    Full Text Available This article will focus on cognitive and mental borders that find expression in perceptions of the foreign other. Perceptions and mental images demonstrate the exchange function of borders. Borders – whether political or cultural – are constructed on the basis of concepts of alterity. For historians of Latin America, the main pole of alterity has been Europe; historians have traditionally concentrated on processes of perception in relation to the “Old World”. From a European perspective, America – at the point of its discovery – constituted a monolithic “New World”.

  4. Justifying molecular images in cell biology textbooks: From constructions to primary data.

    2016-02-01

    For scientific claims to be reliable and productive they have to be justified. However, on the one hand little is known on what justification precisely means to scientists, and on the other the position held by philosophers of science on what it entails is rather limited; for justifications customarily refer to the written form (textual expressions) of scientific claims, leaving aside images, which, as many cases from the history of science show are relevant to this process. The fact that images can visually express scientific claims independently from text, plus their vast variety and origins, requires an assessment of the way they are currently justified and in turn used as sources to justify scientific claims in the case of particular scientific fields. Similarly, in view of the different nature of images, analysis is required to determine on what side of the philosophical distinction between data and phenomena these different kinds of images fall. This paper historicizes and documents a particular aspect of contemporary life sciences research: the use of the molecular image as vehicle of knowledge production in cell studies, a field that has undergone a significant shift in visual expressions from the early 1980s onwards. Focussing on textbooks as sources that have been overlooked in the historiography of contemporary biomedicine, the aim is to explore (1) whether the shift of cell studies, entailing a superseding of the optical image traditionally conceptualised as primary data, by the molecular image, corresponds with a shift of justificatory practices, and (2) to assess the role of the molecular image as primary data. This paper also explores the dual role of images as teaching resources and as resources for the construction of knowledge in cell studies especially in its relation to discovery and justification. Finally, this paper seeks to stimulate reflection on what kind of archival resources could benefit the work of present and future epistemic

    The article discusses a set of pictures that illustrate public health activities, practices, and campaigns against malaria in Brazil from 1918 through 1956. Exemplary of certain key moments in this history, the illustrations belong to three archives from the Casa de Oswaldo Cruz/Fundação Oswaldo Cruz collection: Arquivo Belisário Penna, Arquivto Fundação Rockefeller ("Serviço de Malária do Nordeste" series), and Arquivo Rostan Soares. The article links these photographic records to their specific historical-public health contexts and to the campaign models and strategies represented by each archive. It also draws relations with the 20th -century history of the photographic medium itself. It is argued that these images of malaria constitute prime sources in constructing a visual history of the disease in 20th -century Brazil and of the country's public health history.

    Recently, an electronic delivery for various documents is carried out by Ministry of Land, Infrastructure, Transport and Tourism in construction fields. One of them is image data of construction photography that must be delivered with information of photography management items such as construction name or type of works, etc. However, there is a problem that a lot of cost is needed to treat contents of these items from characters printed and handwritten on blackboard into these image data. In this research, we develop the system which can treat contents of these items by extracting contents of these items from the image data of construction photography taken in various scenes with preprocessing the image, recognizing characters with OCR and correcting error with natural language process. And we confirm the effectiveness of the system, by experimenting in each function of system and in entire system.

    Full Text Available In the respect of value, public procurement in the construction industry belongs to one of the largest ones in the domestic market. Therefore, green procurement for construction works should become the center of attention of public authorities in a broad sense, due to its scale and importance for the sustainable development. The authorities and contracting entities who spend public money should have the opportunity to apply such legal articles and instruments that allow them to both optimize public expenditures and consider the environmental factor, such as decreasing carbon emission. To make the idea of sustainable development a reality as European Union’s the most vital aim, EU law is implemented in Poland. Local authorities’ duty is to appropriately shape their policies and use the vital instrument of sustainable development, namely green public procurement. This paper presents a comparative analysis of legal regulations to illustrate the actual Polish and EU laws concerning the construction industry. Even though the generally applicable law allows to implement the idea of sustainable development efficiently, local self-government units in their regional policies do not report any need for specific solutions, or they do so only occasionally.

  12. Computer-Aided Panoramic Images Enriched by Shadow Construction on a Prism and Pyramid Polyhedral Surface

    Directory of Open Access Journals (Sweden)

    Jolanta Dzwierzynska

    2017-10-01

    Full Text Available The aim of this study is to develop an efficient and practical method of a direct mapping of a panoramic projection on an unfolded prism and pyramid polyhedral projection surface with the aid of a computer. Due to the fact that straight lines very often appear in any architectural form we formulate algorithms which utilize data about lines and draw panoramas as plots of functions in Mathcad software. The ability to draw panoramic images of lines enables drawing a wireframe image of an architectural object. The application of the multicenter projection, as well as the idea of shadow construction in the panoramic representation, aims at achieving a panoramic image close to human perception. The algorithms are universal as the application of changeable base elements of panoramic projection—horizon height, station point location, number of polyhedral walls—enables drawing panoramic images from various viewing positions. However, for more efficient and easier drawing, the algorithms should be implemented in some graphical package. The representation presented in the paper and the method of its direct mapping on a flat unfolded projection surface can find application in the presentation of architectural spaces in advertising and art when drawings are displayed on polyhedral surfaces and can be observed from multiple viewing positions.

  13. The Prevalence of Inappropriate Image Duplication in Biomedical Research Publications

    2016-01-01

    ABSTRACT Inaccurate data in scientific papers can result from honest error or intentional falsification. This study attempted to determine the percentage of published papers that contain inappropriate image duplication, a specific type of inaccurate data. The images from a total of 20,621 papers published in 40 scientific journals from 1995 to 2014 were visually screened. Overall, 3.8% of published papers contained problematic figures, with at least half exhibiting features suggestive of deliberate manipulation. The prevalence of papers with problematic images has risen markedly during the past decade. Additional papers written by authors of papers with problematic images had an increased likelihood of containing problematic images as well. As this analysis focused only on one type of data, it is likely that the actual prevalence of inaccurate data in the published literature is higher. The marked variation in the frequency of problematic images among journals suggests that journal practices, such as prepublication image screening, influence the quality of the scientific literature.

    2017-06-01

    Contemporary research is expanding understandings of occupation beyond that of the individual's doing, including the shared and social nature of occupation. The concept of collective occupation has been introduced to capture this broader understanding. This study aimed to explicate the concept of occupation in a Greek town. Ethnographic methodology was used and primary data were collected through observation, participation, and informal interviews. Analysis involved a hermeneutic process to develop a narrative of occupation in the town, including action, setting, and plots. Occupation, a dynamic and multidimensional process, served to maintain the self, family, and social fabric and balance between and within them. Collective occupation maintained the social fabric through three forms: informal daily encounters in public spaces, organization and associations, and celebration and commemoration. Occupational therapists may consider engaging with the potential power of such collective occupation when working toward social change to enable just and inclusive societies.

    To discuss the actual public image of nurses and other factors that influence the development of nurses' self-concept and professional identity. Nurses have become healthcare professionals in their own right who possess a great deal of knowledge. However, the public does not always value the skills and competences nurses have acquired through education and innovation. Discussion paper. We identified 1216 relevant studies by searching MEDLINE, CINAHL and PsycINFO databases in the period 1997-2010. Finally, 18 studies met our inclusion criteria. The included studies show that the actual public image of nursing is diverse and incongruous. This image is partly self-created by nurses due to their invisibility and their lack of public discourse. Nurses derive their self-concept and professional identity from their public image, work environment, work values, education and traditional social and cultural values. Nurses should work harder to communicate their professionalism to the public. Social media like the Internet and YouTube can be used to show the public what they really do. To improve their public image and to obtain a stronger position in healthcare organizations, nurses need to increase their visibility. This could be realized by ongoing education and a challenging work environment that encourages nurses to stand up for themselves. Furthermore, nurses should make better use of strategic positions, such as case manager, nurse educator or clinical nurse specialist and use their professionalism to show the public what their work really entails. © 2013 John Wiley & Sons Ltd.

    Picture Archiving and Communication System (PACS) has been the main paradigm in supporting medical imaging workflows during the last decades. Despite its consolidation, the appearance of Cross-Enterprise Document Sharing for imaging (XDS-I), within IHE initiative, constitutes a great opportunity to readapt PACS workflow for inter-institutional data exchange. XDS-I provides a centralized discovery of medical imaging and associated reports. However, the centralized XDS-I actors (document registry and repository) must be deployed in a trustworthy node in order to safeguard patient privacy, data confidentiality and integrity. This paper presents XDS for Protected Imaging (XDS-p), a new approach to XDS-I that is capable of being outsourced (e.g. Cloud Computing) while maintaining privacy, confidentiality, integrity and legal concerns about patients' medical information.

  18. Homogeneous Canine Chest Phantom Construction: A Tool for Image Quality Optimization.

    Directory of Open Access Journals (Sweden)

    Ana Luiza Menegatti Pavan

    Full Text Available Digital radiographic imaging is increasing in veterinary practice. The use of radiation demands responsibility to maintain high image quality. Low doses are necessary because workers are requested to restrain the animal. Optimizing digital systems is necessary to avoid unnecessary exposure, causing the phenomenon known as dose creep. Homogeneous phantoms are widely used to optimize image quality and dose. We developed an automatic computational methodology to classify and quantify tissues (i.e., lung tissue, adipose tissue, muscle tissue, and bone in canine chest computed tomography exams. The thickness of each tissue was converted to simulator materials (i.e., Lucite, aluminum, and air. Dogs were separated into groups of 20 animals each according to weight. Mean weights were 6.5 ± 2.0 kg, 15.0 ± 5.0 kg, 32.0 ± 5.5 kg, and 50.0 ± 12.0 kg, for the small, medium, large, and giant groups, respectively. The one-way analysis of variance revealed significant differences in all simulator material thicknesses (p < 0.05 quantified between groups. As a result, four phantoms were constructed for dorsoventral and lateral views. In conclusion, the present methodology allows the development of phantoms of the canine chest and possibly other body regions and/or animals. The proposed phantom is a practical tool that may be employed in future work to optimize veterinary X-ray procedures.

    Zhang, B.; Sang, Jun; Alam, Mohammad S.

    2013-03-01

    An image hiding method based on cascaded iterative Fourier transform and public-key encryption algorithm was proposed. Firstly, the original secret image was encrypted into two phase-only masks M1 and M2 via cascaded iterative Fourier transform (CIFT) algorithm. Then, the public-key encryption algorithm RSA was adopted to encrypt M2 into M2' . Finally, a host image was enlarged by extending one pixel into 2×2 pixels and each element in M1 and M2' was multiplied with a superimposition coefficient and added to or subtracted from two different elements in the 2×2 pixels of the enlarged host image. To recover the secret image from the stego-image, the two masks were extracted from the stego-image without the original host image. By applying public-key encryption algorithm, the key distribution was facilitated, and also compared with the image hiding method based on optical interference, the proposed method may reach higher robustness by employing the characteristics of the CIFT algorithm. Computer simulations show that this method has good robustness against image processing.

    1977-01-01

    The full-scale, three-dimensional presentation of material defects by means of acoustical holography is limited on the one hand by an insufficient resolving power in depth of the procedure and, on the other hand, by the fact that the defects of the material to be examined often reflect mirror-like. Examined is the possible range of reducing these limitations by means of constructing shadow images of defects in ultrasonic testing without - as it is usually done - reconstructing the sonic field reflected by the flow but reconstructing the sonic field diffracted at the flow by means of acoustical holography. It has been shown that acoustical holography, during which the amplitude information is always analyzed as well as - on principle - the phase information, improves the efficiency of ultrasonic testing to a large extent.

Sidoarjo mud volcano phenomena which coincident with drilling activity in 29 May 2006 is making people and government anxious for development a new infrastructure such as high rise building, toll road etc. An understanding of a geological hazard which can be single, sequential or combined events in their origin is the main key importance in subsurface imaging. Geological hazard can be identified by geophysical, geological, geotechnical method. The prompt selection of geophysical method to reveal subsurface condition is very important factor instead of survey design and field data acquisition. Revealing subsurface condition is very important information for site investigation consists of geological, geophysical and geotechnical data, whereas data analysis will help civil engineer design and calculate the construction safety.

    The advancement of technology in recent years has provided the production of increasingly sophisticated devices, aiming to acquire medical images with high technical level and also facilitate the operational readiness of the equipment. In order to ensure the most accurate diagnosis with minimum dose without exposing patients to obtain data and verify the performance of a radiographic system for quality control purposes we use the so-called phantoms. Phantoms are physical or computational models used to simulate the transport of ionizing radiation, their interactions in the tissues of the human body and evaluate the deposition of energy. Besides, they are made from materials with behavior similar to human tissues when exposed to ionizing radiation - the so-called tissue-equivalent materials. This paper describes the construction of a physical phantom that allows the execution of the main acceptance tests of the quality control protocols in digital radiography

    This study investigated how women constructed body image following cancer. Four women, aged 32-67 years, who had experienced breast or bowel cancer took part in a 2-hour, in-depth focus group. Discourse analysis revealed that women orientated to positive aspects of the post-treatment body (silhouette, trust, acceptance) while acknowledging that their experiences were also traumatic (hair loss, scarring, sickness, swelling). Bodies and illness were concealed from public judgment, and women developed new trust in their bodies due to overcoming cancer; post-cancer bodies were accepted despite opportunities for normalisation. Implications for those wanting to support women during and after cancer are discussed.

    The fear of speaking is often cited as the world's most common social phobia. The rapid growth of computer technology enabled us to use virtual reality (VR) for the treatment of the fear of public speaking. There have been two techniques used to construct a virtual environment for the treatment of the fear of public speaking: model-based and movie-based. Virtual audiences and virtual environments made by model-based technique are unrealistic and unnatural. The movie-based technique has a disadvantage in that each virtual audience cannot be controlled respectively, because all virtual audiences are included in one moving picture file. To address this disadvantage, this paper presents a virtual environment made by using image-based rendering (IBR) and chroma keying simultaneously. IBR enables us to make the virtual environment realistic because the images are stitched panoramically with the photos taken from a digital camera. And the use of chroma keying allows a virtual audience to be controlled individually. In addition, a real-time capture technique was applied in constructing the virtual environment to give the subjects more interaction, in that they can talk with a therapist or another subject.

  15. Evaluation of polynomial image deformation for matching of 3D- abdominal MR-images using anatomical landmarks and for atlas construction

    1999-01-01

    The aim of this study is to compare and evaluate the potential usability of linear and non-linear (polynomial) 3D-warping for constructing an atlas by matching abdominal MR-images from a number of different individuals using manually picked anatomical landmarks. The significance of this study lies in the fact that it illustrates the potential to use polynomial matching at a local or organ level. This is a necessary requirement for constructing an atlas and for fine intra-patient image matching and fusion. Finally 3D-image warping using anatomical landmark for inter-patient intra-modality image co-registration and fusion was found to be a very powerful and robust method. Additionally it can be used for intra-patient inter- modality image matching.

  16. THE USE OF PUBLIC RELATIONS IN PROJECTING AN ORGANIZATION'S POSITIVE IMAGE

    Directory of Open Access Journals (Sweden)

    Ioana Olariu

    2017-07-01

    Full Text Available This article is a theoretical approach on the importance of using public relations in helping an organization to project a positive image. The study of the impact information has on the image of organisations seems to be an interesting research topic. Practice has proved that the image of institutions has a patrimonial value and it is sometimes essential in raising their credibility. It can be said that an image is defined as the representation of certain attitudes, opinions or prejudices concerning a person, a group of persons or the public opinion concerning an institution. In other words, an image is the opinion of a person, of a group of persons or of the public opinion regarding that institution. All specialists agree that a negative image affects, sometimes to an incredible extent, the success of an institution. In the contemporary age, we cannot speak about public opinion without taking into consideration the mass media as a main agent in transmitting the information to the public, with unlimited possibilities of influencing or forming it. The plan for the PR department starts with its own declaration of principles, which describes its roles and contribution to the organisation.

    2002-01-01

    Full Text Available This paper shows how a New Zealand company, Fletcher Construction, created wealth in partnership with the state. The first Labour government was elected in 1935 with a firm commitment to full employment and a broad social security system. Because Labour’s determination to get things done through local industry coincided with James Fletcher’s, and then his son’s, drive for company expansion and profits. Fletchers’ design or construction of roads, wharves, saw-mills, flour mills, pulp mills, paper mills, factories, railway stations, university buildings, hospitals, department stores, office blocks, houses, and ownership and management of stone quarries, brickworks and forests, left a mark in almost every town and city in the country. Many projects required building methods and materials new to New Zealand, the innovative use of traditional materials, large-scale plant, specialist, skilled staff and technical know-how from United States and British construction and engineering firms. In this way Fletcher projects drew together many different suppliers, equipment makers, skilled tradesmen and financiers. As a provider of employment in construction and manufacturing, with easy access to established business and political leaders and a powerful influence on policy making, the company became a potent force in New Zealand’s full employment welfare state.

    As lead author of the scientific image processing software package AstroImageJ (AIJ), I will discuss the reasoning behind why we decided to release AIJ to the public, and the lessons we learned related to the development, publication, distribution, and support of AIJ. I will also summarize the AIJ code language selection, code documentation and testing approaches, code distribution, update, and support facilities used, and the code citation and licensing decisions. Since AIJ was initially developed as part of my graduate research and was my first scientific open source software publication, many of my experiences and difficulties encountered may parallel those of others new to scientific software publication. Finally, I will discuss the benefits and disadvantages of releasing scientific software that I now recognize after having AIJ in the public domain for more than five years.

  1. Public foetal images and the regulation of middle-class pregnancy in the online media: a view from South Africa.

    Science.gov (United States)

    Macleod, Catriona; Howell, Simon

    2015-01-01

    Ultrasonography images and their derivatives have been taken up in a range of 'public' spaces, including medical textbooks, the media, anti-abortion material, advertising, the Internet and public health facilities. Feminists have critiqued the personification of the foetus, the bifurcation of the woman's body and the reduction of the pregnant woman to a disembodied womb. What has received less attention is how these images frequently intersect with race, class, gender and heteronormativity in the creation of idealised and normative understandings of pregnancy. This paper focuses on the discursive positioning of pregnant women as 'mothers' and foetuses as 'babies' in online media targeted at a South African audience, where race and class continue to intersect in complex ways. We show how the ontologically specific understandings of 'mummies' and 'babies' emerge through the use of foetal images to construct specific understandings of the 'ideal' pregnancy. In the process, pregnant women are made responsible for ensuring that their pregnancy conforms to these ideals, which includes the purchasing of the various goods advertised by the websites. Not only does this point to a commodification of pregnancy, but also serves to reinforce a cultural understanding of White, middle-class pregnancy as constituting the normative 'correct' form of pregnancy.

    In order to actualize the social sharing and service of the emergency-response information for sudden pollution accidents, the public can share the risk source information service, dangerous goods control technology service and so on, The SQL Server and ArcSDE software are used to establish a spatial database to restore all kinds of information including risk sources, hazardous chemicals and handling methods in case of accidents. Combined with Chinese atmospheric environmental assessment standards, the SCREEN3 atmospheric dispersion model and one-dimensional liquid diffusion model are established to realize the query of related information and the display of the diffusion effect under B/S structure. Based on the WebGIS technology, C#.Net language is used to develop the sudden environmental pollution public service platform. As a result, the public service platform can make risk assessments and provide the best emergency processing services.

    To examine the possibilities for research into news reporting and its role in reflecting and informing public and political beliefs and action in relation to alcohol and drinking practices. Studies on media and alcohol, focusing on the role of media in relation to alcohol consumption and drinking-related practices, policies and beliefs. Most research on alcohol and media has focused on either advertising or entertainment media content, rather than on news reporting and its wider social implications. The role of news reporting could usefully be widened. We offer a framework for analysing the role of news media in relation to public debate and practice with regard to alcohol and drinking.

  7. Collective symbolic coping with new technology: Knowledge, images and public discourse.

    Wagner, Wolfgang; Kronberger, Nicole; Seifert, Franz

    2002-09-01

    Using data from policy analyses, media analyses and a European-wide survey about public perceptions of biotechnology conducted in 1996 and again in 1999, it is shown how a country's public develops an everyday understanding of a new technology (genetic modification) construed as potentially harmful by the media. To understand the reliance on images and related beliefs, we propose a theory of collective symbolic coping. It identifies four steps: first, the creation of awareness; second, production of divergent images; third, convergence upon a couple of dominant images in the public sphere; fourth, normalization. It is suggested that symbolic coping occurs in countries where a recent increase in policy activity and of media reporting has alerted the public; that this public show a high proportion of beliefs in menacing images; that these beliefs are relatively independent of pre-existing popular science knowledge; and that they are functionally equivalent to scientific knowledge in providing judgmental confidence and reducing self-ascribed ignorance. These propositions are shown to be true in Austria and Greece. Several implications of the theory are discussed, including social representation theory and public understanding of science.

    The construction of public rental needs much money and usually takes a long time , thus it can not only rely on limited financial investment , so financing becomes a bottleneck restricting the construction of public rental .At present, bank loans and project financing are two main financing models of the public rental , while PPP, REITs and other ways are rarely used .This paper introduces the traditional financing methods , focusing on the PPP and REITs . The paper summarizes the pros and cons of nine financing models and concludes that bank loans , project financing , BT, BOT, PPP, TOT, bonds, public rental REITs and ABS can pave the way for opening up social capital into the field of investment and construction of public rental channel .It is suggested that China raise housing finance though multiple channels , and seek to comply with China's specific situation of public rental financing model .%公租房建设资金需求量大、占用时间长,依靠有限的财政投入难以满足,因此,公租房融资成为制约公租房建设的瓶颈。目前,公租房融资主要使用银行贷款、项目融资等方式,而其他市场化融资方式使用较少。为拓宽公租房融资渠道,应积极引入并大力发展REITs、PPP等模式。其中,REITs模式的市场化程度较高,专业性更强,要求有完善的法律体系作保障;而PPP模式强调在政府引导下引入私人资本,以分担风险和成本。总体来说,REITs、PPP都将是中国公租房融资有益尝试。

  9. New gonad protector for public survey X-ray images

    Energy Technology Data Exchange (ETDEWEB)

    Joos, M.

    1976-01-01

    A new gonad shield intended to be used for pubic survey X-ray images is introduced. This protector is mounted on the light sight and produces a shadow free of central radiation on the patient's body. The shield provides such a shape that in women the area limited by the terminal line and in which 95% of the ovaria are situated, is covered, and that in men the region below the pubic angle is protected. The 2 mm thick lead shield has dimensions of 4.0 to 2.5 cm and is inserted into a plexiglass ruler which lies freely movable on a plexiglass plate under the light sight. This shield was tested on the water phantom and on 125 patients. With this protector it was possible to lower the surface dosages calculated by film dosimeters to 20% in women, and also to reduce the gonade dosages to 9% of the dosages without protection. The position of the new gonad protector at a distance from the body provides several advantages: the shield does not alter its position when the patient moves, the protector does not slip off the abdomen in adipose female patients, the radiation protected region has always the same extent, independent from the abdominal curvature of the female patient, the hygienic problems are eliminated, and the shield can be used for both sexes.

    Research shows that constraining aspects of male gender norms negatively influence both women's and men's health. Messaging that draws on norms of masculinity in health programming has been shown to improve both women's and men's health, but some types of public health messaging (e.g., Man Up Monday, a media campaign to prevent the spread of sexually transmitted infections) can reify harmful aspects of hegemonic masculinity that programs are working to change. We critically assess the deployment of hegemonic male norms in the Man Up Monday campaign. We draw on ethical paradigms in public health to challenge programs that reinforce harmful aspects of gender norms and suggest the use of gender-transformative interventions that challenge constraining masculine norms and have been shown to have a positive effect on health behaviors.

    1977-01-01

    One of the urgent problems now confronting the atomic power development is to search a legal measure for obtaining the public acceptance with the premise of understanding and cooperation, and it is discussed. Attention is paid to the present status of Japan, in which the legal system is incomplete, and the administrative process unspecified in laws and ordinances must be considered seriously. The first section deals with the public hearing and its problems concerning the installation of reactors. The list of twelve main problems that were pointed out in the manual of holding the public hearing by the council of Japanese scientists is given. The most important points are as follows: (a) the public hearing must be held at such time that the feed back is possible to reflect the points of discussion to the final determination; (b) enough data and information must be provided and noticed beforehand, and the sufficient opportunity of discussion must be ensured; and (c) the scientists recommended by local inhabitants must be included in order to assist laity, and the points of discussion must be adjusted scientifically. The second section deals with the popular participation in fact. In conclusion, it is said that there are several traps in the ''inhabitant participation'', and it is the danger to change into the ''engineering of consent'' which fulfill buffer functions for expecting and avoiding the repulsion and criticism of inhabitants against the administration. It may be only eyes of scientists to check the dark reversal from the conveyance of will and ideas of inhabitants to the authority. (Iwakiri, K.)

  12. Constructing Public Relations as a Women’s Profession IN Russia / Construyendo las relaciones públicas como una profesión de mujeres en Rusia

    Directory of Open Access Journals (Sweden)

    Katerina Tsetsura

    2014-10-01

    Full Text Available This study examines how public relations can be understood, perceived, and ultimately constructed as a profession through professionals’ everyday discourses. The article explores what it means for public relations practitioners to be considered professionals in the field that is actively developing in many parts of the world. The goal was to expand the understanding of what constitutes the profession of public relations through a qualitative analysis of work-centered discourses of practitioners. The results demonstrated that, specifically in Russia, similar to many other countries, public relations is often seen as a profession that is better suited for women than men due to historical, socio-economic, and societal factors as well as due to pre-conceived notions about public relations. This study contributes to a new theoretical understanding of public relations as a socially constructed profession and demonstrates how construction of this profession can both propel and slow down the development of the practice.

    2014-08-01

    A key challenge of preconception healthcare is identifying how it can best be delivered at a population level. To review current strategies of preconception healthcare, explore methods of preconception healthcare delivery, and develop public health models which reflect different preconception healthcare pathways. Preconception care strategies, programmes and evaluations were identified through a review of Medline and Embase databases. Search terms included: preconception, pre-pregnancy, intervention, primary care, healthcare, model, delivery, program, prevention, trial, effectiveness, congenital disorders OR abnormalities, evaluation, assessment, impact. Inclusion criteria for review articles were: (1) English, (2) human subjects, (3) women of childbearing age, (4) 1980–current data, (5) all countries, (6) both high risk and universal approaches, (7) guidelines or recommendations, (8) opinion articles, (9) experimental studies. Exclusion criteria were: (1) non-human subjects, (2) non-English, (3) outside of the specified timeframe, (4) articles on male healthcare. The results of the literature review were synthesised into public health models of care: (1) primary care; (2) hospital-based and inter-conception care; (3) specific preconception care clinics; and, (4) community outreach. Fifteen evaluations of preconception care were identified. Community programmes demonstrated a significant impact on substance use, folic acid supplementation, diabetes optimization, and hyperphenylalaninemia. An ideal preconception visits entail risk screening, education, and intervention if indicated. Subsequently, four public health models were developed synthesizing preconception care delivery at a population level. Heterogeneity of risk factors, health systems and strategies of care reflect the lack of consensus about the best way to deliver preconception care. The proposed models aim to reflect differing aspects of preconception healthcare delivery.

    The wavelet transform multi-resolution analysis for articles has revealed the lines of thought. The articles have carried in papers concerning a local referendum about the construction of a nuclear power station in a residential area, a seaside, a farm and a town. Employing this new method has clarified the line of thought in these four areas has been clarified. In the seaside three strong support opinions appeared in the first, middle and last part of the press, with a small number of adverse opinions at the beginning and at the end. In the town no adverse opinion was found but a small number of supporting opinions appeared in the middle of the article. Our method contributes to establishing an objective social consensus because the lines of thought would be based on interviewer's knowledge that contributes to mutual understandings. (author)

  16. Evaluation of public and worker exposure due to naturally occurring asbestos in gravel discovered during a road construction project.

    Perkins, Robert A; Hargesheimer, John; Vaara, Leah

    2008-09-01

    During a repair and reconstruction project of an unpaved highway in a remote region of Alaska, workers discovered, after construction had commenced, that the materials used from a local material site contained asbestos (variously described as tremolite or actinolite). The regional geology indicated the presence of ultramafic rock, which often contains asbestos. Evaluation of asbestos exposure to workers, their equipment, and living quarters was required, as was the possible future exposure of workers and the general public to asbestos already used in the roadway construction. In addition, a decision was needed on whether to use materials from the contaminated site in the future. Of the almost 700 breathing zone air monitoring samples taken of the workers, 3% of the samples indicated exposures at or near 0.1 f/cc by the National Institute for Occupational Safety and Health (NIOSH) 7400 phase contrast microscopy (PCM) procedure. Thirty-six of the PCM samples underwent transmission electron microscopy (TEM) analysis by the NIOSH 7402 procedure, which indicated that about 40% of the fibers were asbestos. After classifying samples by tasks performed by workers, analysis indicated that workers, such as road grader operators who ground or spread materials, had the highest exposures. Also, monitoring results indicated motorist exposure to be much less than 0.1 f/cc. The design phase of any proposed construction project in regions that contain ultramafic rock must consider the possibility of amphibole contamination of roadway materials, and budget for exploration and asbestos analysis of likely materials sites.

    Full Text Available Abstract: In this paper we analyze the visual cultures surrounding HIV and AIDS; we are especially interested in tracking the actors, discourses and visual cultures involved in AIDS prevention in Mexico for a period of twenty years: from 1985 to 2005. We use media studies to better comprehend how HIV and AIDS further medicalized human bodies by mobilizing specific discourses, metaphors and visual resources that, though promoting a better understanding of how HIV could be acquired and how it could be prevented, also generated new representations of sexuality, bodies and persons living with HIV or AIDS often biased in favor of different systems of value. Moreover, we try to offer a general characterization of the different publics that were targeted and preconceptions involving ethnicity, gender, sexual orientation, geography and membership in different sociocultural groups.

    2007-07-15

    The aim of this study was to evaluate three-dimensional Fourier transformation-constructive interference in steady-state (CISS) imaging as a preoperative anatomical evaluation of the relationship between the placode, spinal nerve roots, CSF space, and the myelomeningocele sac in neonates with lumbosacral myeloschisis. Five consecutive patients with lumbosacral myeloschisis were included in this study. Magnetic resonance (MR) CISS, conventional T1-weighted (T1-W) and T2-weighted (T2-W) images were acquired on the day of birth to compare the anatomical findings with each sequence. We also performed curvilinear reconstruction of the CISS images, which can be reconstructed along the curved spinal cord and neural placode. Neural placodes were demonstrated in two patients on T1-W images and in three patients on T2-W images. T2-W images revealed a small number of nerve roots in two patients, while no nerve roots were demonstrated on T1-W images. In contrast, CISS images clearly demonstrated neural placodes and spinal nerve roots in four patients. These findings were in accordance with intraoperative findings. Curvilinear CISS images demonstrated the neuroanatomy around the myeloschisis in one slice. The resulting images were degraded by a band artifact that obstructed fine anatomical analysis of the nerve roots in the ventral CSF space. The placode and nerve roots could not be visualized in one patient in whom the CSF space was narrow due to the collapse of the myelomeningocele sac. MR CISS imaging is superior to T1-W and T2-W imaging for demonstrating the neural placode and nerve roots, although problems remain in terms of artifacts. (orig.)

    Full Text Available The article presents a method for recognising qualitative and quantitative dimensions of open urban space in the user’s perceptual image. It stems from the hypothesis that the open urban space in mental perception isn’t a uniform continuum, which in general applies to its physical phenomenon. It discloses where and how users experience the limits of real open public space that they occupy and what they perceive as the neighbourhood of such a place. Therefore it researches rules applied by the user to mentally structure physically continuous space into smaller units and then reassemble these into a network. Knowledge of such rules enables expansion of open urban public spaces, which user’s experience as positive, into the wider area, thus revitalising those neighbouring spaces that are perceived as negative or are completely absent in the mental image and consequentially unused. The presence of people is in fact the essential component of quality public spaces.

    This study discusses the role of public relations for image creating in health services. Hospitals require public relations activities to distinguish them from competitors, provide bidirectional communication between the society and the hospital, and assist to create of a strong hospital image and culture. A satisfaction survey was conducted on 264 patients who have received health services at Maltepe University Hospital. The research focused on how the Hospital's examination, care, catering and physical services; doctor and nurse politeness towards patients and patient relatives, their attitudes and behaviors; examination, check-in, bedding and discharge operations; public relations activities in and out of the hospital were perceived. Another subject of the study was the degree of recommendation of patients who have been served by the hospital's health services to prospective patients seeking treatment.

  6. Insights in public health: systems thinking: basic constructs, application challenges, misuse in health, and how public health leaders can pave the way forward.

    The strengthening of health systems is fundamental to improving health outcomes, crisis preparedness, and our capacity to meet global challenges, such as accelerating progress towards the Millennium Development Goals, reducing maternal and child mortality, combating HIV, malaria and other diseases, limiting the effects of a new influenza pandemic, and responding appropriately to climate change. To meet these complex needs, the Association of Schools and Programs in Public Health, the World Health Organization, and the Institute of Medicine promote systems thinking as the only sensible means to respond to issues that greatly exceed the normal capacity of health and medical services. This paper agrees with the application of systems thinking but argues that health organizations have misunderstood and misapplied systems thinking to the extent that the term has become meaningless. This paper presents the basic constructs of systems thinking, explains why systems thinking has been misapplied, examines some misapplications of systems thinking in health, and suggests how the concept can be applied correctly to medicine and public health to achieve the reason it was adopted in the first place.

  7. News Media Power and Public Policy: The Mediatized Construction of Women Trafficking for Sexual Exploitation

    2018-04-01

    Full Text Available Like other areas of violence against women, sex trafficking has become in the last decade increasingly politicized in Portuguese society, with the news media attaching important visibility to it, both for public awareness purposes and government reaction. This happened after the dismantling of a chain of striptease clubs, suspected of hosting trafficking activities. Known as the “Passerelle case”, this event attracted great media attention and brought to the public sphere the problem of trafficking in women for sexual purposes. This article looks at the Portuguese press to understand in what ways the news coverage of the case paved the way for the social and political acknowledgment of this issue, and to what extent it favored an understanding capable of making a real difference in the lives of women. It argues that, despite the news media’s undeniable involvement in sociopolitical changes claimed by feminism, its emancipatory potential remained unexplored. Tal como outras áreas da violência contra as mulheres, o tráfico para exploração sexual tornou-se na última década crescentemente politizado na sociedade portuguesa, com os media de informação a concederem a esta prática uma importante visibilidade, tanto no domínio da conscientização pública como no plano da reação governamental. Isso aconteceu após o desmantelamento de uma cadeia de clubes de striptease, suspeita de atividades de tráfico. Conhecido como o “caso Passerelle”, este acontecimento atraiu elevada atenção mediática e fez aflorar no espaço público o tráfico para fins sexuais. Este artigo analisa a imprensa portuguesa para compreender de que forma a cobertura noticiosa do caso abriu caminho para o reconhecimento social e político deste problema e em que medida favoreceu uma compreensão capaz de fazer diferença na vida das mulheres. Defende-se que, apesar do inegável envolvimento dos meios de comunicação nas mudanças sociopol

  10. The non-display of authentic distress: public-private dualism in young people's discursive construction of self-harm.

    Scourfield, Jonathan; Roen, Katrina; McDermott, Elizabeth

    2011-07-01

    This article draws from focus groups and interviews investigating how young people talk about self-harm. Some of the research participants had personal experience of self-harm but this was not a prerequisite for their inclusion in the study. Thematic coding was used initially to organise and give an overview of the data, but the data were subsequently analysed using a discourse analytic approach. The article focuses on the young people's constructions of deliberate self-harm such as 'cutting'. Throughout the focus groups and interviews, a dichotomy was set up by the young people between authentic, private self-harm which is rooted in real distress (and warrants a sympathetic response) and public, self-indulgent attempts to seek attention. This dualistic construction is discussed in some detail and located in various socio-cultural contexts. It is argued that the dualism illustrates contemporary ambivalence about mental health and youth. © 2011 The Authors.

  11. Images of eyes enhance investments in a real-life public good.

    Directory of Open Access Journals (Sweden)

    Damien Francey

    Full Text Available A key issue in cooperation research is to determine the conditions under which individuals invest in a public good. Here, we tested whether cues of being watched increase investments in an anonymous public good situation in real life. We examined whether individuals would invest more by removing experimentally placed garbage (paper and plastic bottles from bus stop benches in Geneva in the presence of images of eyes compared to controls (images of flowers. We provided separate bins for each of both types of garbage to investigate whether individuals would deposit more items into the appropriate bin in the presence of eyes. The treatment had no effect on the likelihood that individuals present at the bus stop would remove garbage. However, those individuals that engaged in garbage clearing, and were thus likely affected by the treatment, invested more time to do so in the presence of eyes. Images of eyes had a direct effect on behaviour, rather than merely enhancing attention towards a symbolic sign requesting removal of garbage. These findings show that simple images of eyes can trigger reputational effects that significantly enhance on non-monetary investments in anonymous public goods under real life conditions. We discuss our results in the light of previous findings and suggest that human social behaviour may often be shaped by relatively simple and potentially unconscious mechanisms instead of very complex cognitive capacities.

    Public spaces in a planned housing is a place of social interaction for every visitor of public space. The research on public space image uses four public spaces that meet the criteria of public space such as pedestrian sidewalks, public park, water front and worship place. Research on the perception of public space is interesting to investigate because housing development is part of the forming of a society that should design with proper architectural considerations. The purpose of this research is to know the image of public space on the planned housing in Medan City based on the mapping of environmental and behavior cognition and to know the difference between the image that happened to four group respondent. The research method of architecture used in this research is a descriptive qualitative method with case study approach (most similar case). Analysis of data used using mental maps and questionnaires. Then the image of public space is formed based on the elements of public space, wayfinding, route choice, and movement. The image difference that occurs to the housing residents and architecture students, design and planning are outstanding, visitors to the public housing space is good, people who have never visited the public space is inadequate.

    The topographic measurement of muddy tidal flat is restricted by the difficulty of access to the complex, wide-range and dynamic tidal conditions. Then the waterline detection method (WDM) has the potential to investigate the morph-dynamics quantitatively by utilizing large archives of satellite images. The study explores the potential for using WDM with BJ-1 small satellite images to construct a digital elevation model (DEM) of a wide and grading mudflat. Three major conclusions of the study are as follows: (1) A new intelligent correlating model of waterline detection considering different tidal stages and local geographic conditions was explored. With this correlative algorithm waterline detection model, a series of waterlines were extracted from multi-temporal remotely sensing images collected over the period of a year. The model proved to detect waterlines more efficiently and exactly. (2) The spatial structure of elevation superimposing on the points of waterlines was firstly constructed and a more accurate hydrodynamic ocean tide grid model was used. By the newly constructed abnormal hydrology evaluation model, a more reasonable and reliable set of waterline points was acquired to construct a smoother TIN and GRID DEM. (3) DEM maps of Bohai Bay, with a spatial resolution of about 30 m and height accuracy of about 0.35 m considering LiDAR and 0.19 m considering RTK surveying were constructed over an area of about 266 km2. Results show that remote sensing research in extremely turbid estuaries and tidal areas is possible and is an effective tool for monitoring the tidal flats.

    The enhancement of the energy efficiency reduces the life cycle costs of real estates, and is an important component in achieving global climate goals. In the construction and operation of public building constructions, the state has to assume the function of a role model. Due to the budgetary position of the public authority continuously in deficit, the alternative form of procurement public-private partnerships will become increasingly important. The author of the contribution under consideration reports on the design of building construction projects of public-private partnerships in order to guarantee an energy efficient operation. A reference model with process descriptions for the single phases of the project is developed. The author describes the possible benefit of this model by means of an application example.

    Purpose: To assess image quality and radiation dose reduction in abdominal CT imaging, physical phantoms having realistic background textures and lesions are highly desirable. The purpose of this work was to construct a liver phantom with realistic background and lesions using patient CT images and a 3D printer. Methods: Patient CT images containing liver lesions were segmented into liver tissue, contrast-enhanced vessels, and liver lesions using commercial software (Mimics, Materialise, Belgium). Stereolithography (STL) files of each segmented object were created and imported to a 3D printer (Object350 Connex, Stratasys, MN). After test scans were performed to map the eight available printing materials into CT numbers, printing materials were assigned to each object and a physical liver phantom printed. The printed phantom was scanned on a clinical CT scanner and resulting images were compared with the original patient CT images. Results: The eight available materials used to print the liver phantom had CT number ranging from 62 to 117 HU. In scans of the liver phantom, the liver lesions and veins represented in the STL files were all visible. Although the absolute value of the CT number in the background liver material (approx. 85 HU) was higher than in patients (approx. 40 HU), the difference in CT numbers between lesions and background were representative of the low contrast values needed for optimization tasks. Future work will investigate materials with contrast sufficient to emulate contrast-enhanced arteries. Conclusion: Realistic liver phantoms can be constructed from patient CT images using a commercial 3D printer. This technique may provide phantoms able to determine the effect of radiation dose reduction and noise reduction techniques on the ability to detect subtle liver lesions in the context of realistic background textures

    Collective images of ageing influence attitudes towards ageing and health- related activities. The aim of this study was to explore images of ageing and old age in magazines published by public health institutions, namely health insurance companies and pharmacies. A standardized content analysis was conducted covering age-related articles (n=146) and accompanying photographs (n=218) of public health institutions. The stock of material comprises age-related articles of all magazines published 2012-2013 of 2 public health insurance companies (Allgemeine Ortskrankenkasse: "Bleib gesund", Barmer Ersatzkasse: "Gesundheit konkret"), 2 private health insurance companies (Gothaer Versicherung: "Gothaer magazin", Deutsche Krankenversicherung: "DKV impulse") and 2 consumer magazines of pharmacies ("Apothekenumschau","Senioren Ratgeber"). Illness turns out to be the most often focused main theme and key issue of age-related articles. With reference to the central dimensions of somatic culture - health, body-centered performance and appearance - most of the articles focus on deficits of old age, in particular illness and decrease of performance, and thus communicate a negative image of ageing. The visual presentation of elderly people is much more positive. There are various differences in the communication of images of ageing between the 2 types of magazines, with the consumer magazines of the pharmacy covering a broader spectrum of topics, referring more often to a healthy lifestyle and prevention and communicating a more multifaceted image of old age and ageing in comparison to the membership magazines of health insurance companies. Institutions of public health have many duties and responsibilities. One of these is to strengthen health competencies and locus of control of the population - in our case - elderly people. As images of ageing influence attitudes towards ageing and health-related activities, it seems to be sensible and of good economic sense to communicate a

    Recently, optical asymmetric cryptosystem (OACS) has became the focus of discussion and concern of researchers. Some researchers pointed out that OACS was not tenable because of misunderstanding the concept of asymmetric cryptosystem (ACS). We propose an improved cryptosystem using RSA public-key algorithm based on existing OACS and the new system conforms to the basic agreement of public key cryptosystem. At the beginning of the encryption process, the system will produce an independent phase matrix and allocate the input image, which also conforms to one-time pad cryptosystem. The simulation results show that the validity of the improved cryptosystem and the high robustness against attack scheme using phase retrieval technique.

    This paper describes the construction of a static 3D ultrasonography image by tracking the radiation beam position during the handy operation of a 1D array probe to enable point-of-care use. The theoretical model of the transformation from the translational and rotational information of the sensor mounted on the probe to the reference Cartesian coordinate system was given. The signal amplification and serial communication interface module was made using a commercially available sensor. A test phantom was also made using silicone putty in a donut shape. During the movement of the hand-held probe, B-mode movie and sensor signals were recorded. B-mode images were periodically selected from the movie, and the gray levels of the pixels for each image were converted to the gray levels of 3D voxels. 3D and 2D images of arbitrary cross-section of the B-mode type were also constructed from the voxel data, and agreed well with the shape of the test phantom.

    Trunk voxel phantom was constructed by using whole body CT images and tumor doses were calculated by using Monte Carlo method after simulating situation of radiotheraphy treatment planning. The whole body CT images of VHP (Visual Human Project) man were acquired from National Library of Medicine of USA. 153 slices of trunk part were extracted from whole body CT images and MCNP4B, a general purpose Monte Carlo code, was used for dose calculation. Gray scale of CT images were converted into density of medium and processed into trunk voxel phantom ported to MCNP4B input deck. The conversion method was verified by comparing cross sectional images of voxel phantom with original CT images. Tumor volumes with diameter of 3 cm were defined in liver, stomach and right lung and irradiated with 5, 10 and 15 MeV gamma beam with diameter of 6 cm. The technical basis for 3D dose calculation was established through this study for localization of 3D RTP system.

    We propose an unbiased implicit-reference group-wise (IRG) image registration method and demonstrate its applications in the construction of a brain white matter fiber tract atlas and the analysis of resting-state functional MRI (fMRI) connectivity. Most image registration techniques pair-wise align images to a selected reference image and group analyses are performed in the reference space, which may produce bias. The proposed method jointly estimates transformations, with an elastic deformation model, registering all images to an implicit reference corresponding to the group average. The unbiased registration is applied to build a fiber tract atlas by registering a group of diffusion tensor images. Compared to reference-based registration, the IRG registration improves the fiber track overlap within the group. After applying the method in the fMRI connectivity analysis, results suggest a general improvement in functional connectivity maps at a group level in terms of larger cluster size and higher average t-scores.

    One of the main characteristics of the Internet era we are living in, is the free and online availability of a huge amount of data. This data is of varied reliability and accuracy and exists in various forms and formats. Often, it is cross-referenced and linked to other data, forming a nexus of text, images, animation and audio enabled by hypertext and, recently, by the Web3.0 standard. Our main goal is to enable historians, architects, archaeolo- gists, urban planners and affiliated professionals to reconstruct views of historical monuments from thousands of images floating around the web. This paper aims to provide an update of our progress in designing and imple- menting a pipeline for searching, filtering and retrieving photographs from Open Access Image Repositories and social media sites and using these images to build accurate 3D models of archaeological monuments as well as enriching multimedia of cultural / archaeological interest with metadata and harvesting the end products to EU- ROPEANA. We provide details of how our implemented software searches and retrieves images of archaeological sites from Flickr and Picasa repositories as well as strategies on how to filter the results, on two levels; a) based on their built-in metadata including geo-location information and b) based on image processing and clustering techniques. We also describe our implementation of a Structure from Motion pipeline designed for producing 3D models using the large collection of 2D input images (>1000) retrieved from Internet Repositories.

    Entomological studies conducted in large hydroelectric infrastructure projects are a tool for the prevention and control of vector-borne diseases. These diseases emerge as a consequence of changes made to the terrain that often increase the natural and artificial mosquito larval habitats. Many of these insects are of public health importance and population increases result in an increased risk of disease transmission. The culicine (mosquito) and phlebotomine (sand fly) populations were characterized in the area of the Porce II and Porce III hydroelectric projects of Antioquia between 1990 to 2009. Periodical entomological samplings were made in the area of impact, in the workers camps, and construction sites. Adult specimens were captured with nets, Shannon light traps, CDC light traps, and protected human bait. Mosquito larvae of the following species were identified: Culex coronator, Culex nigripalpus, Culex corniger, Culex quinquefasciatus and Limatus durhami. The most frequently identifiers of larval habitats were low tanks, waste cans, tires, and aquatic plants. Aedes aegypti specimens were captured in only two rural locations from two municipalities within the area of influence. Specimens from the following mosquito genera were captured in forest areas: Aedes, Mansonia, Culex, Psorophora, Wyeomyia, Phonyomyia, Uranotaenia, Haemagogus and Sabethes. The most important mosquito found was Haemogogus janthinomis, an efficient yellow fever vector in Colombia. The area has been endemic for leishmaniasis and in the current study, 20 species of Lutzomyia sand flies, potential vectors, were identified. Among malaria vectors, the most important species found in the area were Anopheles nuneztovari and Anopheles pseudopunctipennis. A wide variety of vectors were discovered in the area of the Porce II and Porce III hydroelectric projects, and many of these were relevant for public health. Further monitoring will be necessary to minimize disease transmission risks among the

    The principle of radiodiagnosis consists in the fact the X-ray beam is attenuated at different degrees by distinct tissues. For this reason, the anatomical structures have distinct radiological opacities, that produce the radiographic image. The progresses in radiology are related to the development if new radiographic image formation systems that enable an amplification in the quality, with low dose and/or risk to the patient. The objective of this work is the sensitometric valuation of a screen-film combination, that is still the most used, for the standardization, of radiographic images. Thinking about this, were constructed homogeneous phantoms of the chest, skull and pelvis, for the calibration of X-ray beams, with the purpose of obtaining radiographic images of good quality, basing in the routine of a radiodiagnosis service and in the scientific knowledge. Questions were approached about the choice of the suitable equipment, that allow the obtention of k Vp and m As combinations, to produce radiographic images of good quality, and the reproduction of these combinations to any conventional equipment of diagnostic X-rays. Also presented are the comparison of the doses imparted by these combinations and those used in routine of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto`s radiodiagnosis service.

    Özkaya, Sait Ismail

    2002-04-01

    KINKFOLD is an AutoLISP program designed to construct geological cross-sections from borehole image or dip meter logs. The program uses the kink-fold method for cross-section construction. Beds are folded around hinge lines as angle bisectors so that bedding thickness remains unchanged. KINKFOLD may be used to model a wide variety of parallel fold structures, including overturned and faulted folds, and folds truncated by unconformities. The program accepts data from vertical or inclined boreholes. The KINKFOLD program cannot be used to model fault drag, growth folds, inversion structures or disharmonic folds where the bed thickness changes either because of deformation or deposition. Faulted structures and similar folds can be modelled by KINKFOLD by omitting dip measurements within fault drag zones and near axial planes of similar folds.

    Ladar system simulation is to simulate the ladar models using computer simulation technology in order to predict the performance of the ladar system. This paper presents the developments of laser imaging radar simulation for domestic and overseas studies and the studies of computer simulation on ladar system with different application requests. The LadarSim and FOI-LadarSIM simulation facilities of Utah State University and Swedish Defence Research Agency are introduced in details. This paper presents the low level of simulation scale, un-unified design and applications of domestic researches in imaging ladar system simulation, which are mostly to achieve simple function simulation based on ranging equations for ladar systems. Design of laser imaging radar simulation with open and modularized structure is proposed to design unified modules for ladar system, laser emitter, atmosphere models, target models, signal receiver, parameters setting and system controller. Unified Matlab toolbox and standard control modules have been built with regulated input and output of the functions, and the communication protocols between hardware modules. A simulation based on ICCD gain-modulated imaging ladar system for a space shuttle is made based on the toolbox. The simulation result shows that the models and parameter settings of the Matlab toolbox are able to simulate the actual detection process precisely. The unified control module and pre-defined parameter settings simplify the simulation of imaging ladar detection. Its open structures enable the toolbox to be modified for specialized requests. The modulization gives simulations flexibility.

    2016-12-01

    Full Text Available The aim of this study is to explore the means, the methods, and the techniques of public diplomacy that a country in crisis, such as Greece, should use. The paper addresses the very issues of whether a country in crisis can conduct public diplomacy and whether it should be recognized as a legitimate and powerful actor in the field. In a broader sense, it focuses on the processes that a country should follow and how a better understanding and framing of its situation, principles, and policy can be provided. A crucial factor for such countries is the choice of communication channels, which includes traditional tools like press releases, letters to editor, editorials, interviews, or more active tools like social media, events, campaigns, and networking. In this paper, three dimensions of public diplomacy are examined, and appropriate tools to be developed in the short, medium and long-term are proposed. The results of the study are based on case studies, methods, and tools employed by Greece during the last years that the country has faced a huge economic crisis. There is a short presentation on the methods that Greece tries to adopt in order to enhance its image worldwide.

    Some former research have been made for obtaining a new type of wavelet. In case of iris recognition using orthogonal or biorthogonal wavelets, it had been obtained that Haar filter is most suitable to recognize the iris image. However, designing the new wavelet should be done to find a most matched wavelet to extract the iris image features, for which we can easily apply it for identification, recognition, or authentication purposes. In this research, a new biorthogonal wavelet was designed based on Haar filter properties and Haar's orthogonality conditions. As result, it can be obtained a new biorthogonal 5/7 filter type wavelet which has a better than other types of wavelets, including Haar, to extract the iris image features based on its mean-squared error (MSE) and Euclidean distance parameters.

    Diabetic macular edema (DME) is a common vision threatening complication of diabetic retinopathy. In a large scale screening environment DME can be assessed by detecting exudates (a type of bright lesions) in fundus images. In this work, we introduce a new methodology for diagnosis of DME using a novel set of features based on colour, wavelet decomposition and automatic lesion segmentation. These features are employed to train a classifier able to automatically diagnose DME through the presence of exudation. We present a new publicly available dataset with ground-truth data containing 169 patients from various ethnic groups and levels of DME. This and other two publicly available datasets are employed to evaluate our algorithm. We are able to achieve diagnosis performance comparable to retina experts on the MESSIDOR (an independently labelled dataset with 1200 images) with cross-dataset testing (e.g., the classifier was trained on an independent dataset and tested on MESSIDOR). Our algorithm obtained an AUC between 0.88 and 0.94 depending on the dataset/features used. Additionally, it does not need ground truth at lesion level to reject false positives and is computationally efficient, as it generates a diagnosis on an average of 4.4 s (9.3 s, considering the optic nerve localization) per image on an 2.6 GHz platform with an unoptimized Matlab implementation.

    Previous studies have reported equivocal findings concerning the impact of wearing a hijab, or Islamic head- and body-cover, on Muslim women's body image. Here, we sought to examine that impact using a larger sample of Muslim women than has been relied upon and a wider range of body image measures. A total of 587 British Muslim women completed a battery of scales assessing their frequency and conservativeness of hijab use, body image variables, attitudes towards the media and beauty ideals, importance of appearance, and religiosity. Preliminary results indicated that 218 women never used the hijab and 369 women used some form of the hijab at least rarely. Controlling for religiosity, women who wore the hijab had more positive body image, lower internalization of media messages about beauty standards, and placed less importance on appearance than women who did not wear the hijab. Among women who wore the hijab, hijab use significantly predicted weight discrepancy and body appreciation over and above religiosity. These results are discussed in terms of the possible protective impact among British Muslim women of wearing the hijab. © 2013 The British Psychological Society.

    Research was conducted to acquire knowledge of the ultraviolet and visible spectrums from 300 -800 nm of some common varieties of Japanese citrus, to investigate the best wave-lengths for fluorescence excitation and the resulting fluorescence wave-lengths and to provide a scientific background for the best quality fluorescent imaging technique for detecting surface defects of citrus. A Hitachi U-4000 PC-based microprocessor controlled spectrophotometer was used to measure the absorption spectrum and a Hitachi F-4500 spectrophotometer was used for the fluorescence and excitation spectrums. We analyzed the spectrums and the selected varieties of citrus were categorized into four groups of known fluorescence level, namely strong, medium, weak and no fluorescence.The level of fluorescence of each variety was also examined by using machine vision system. We found that around 340-380 nm LEDs or UV lamps are appropriate as lighting devices for acquiring the best quality fluorescent image of the citrus varieties to examine their fluorescence intensity. Therefore an image acquisition device was constructed with three different lighting panels with UV LED at peak 365 nm, Blacklight blue lamps (BLB) peak at 350 nm and UV-B lamps at peak 306 nm. The results from fluorescent images also revealed that the findings of the measured spectrums worked properly and can be used for practical applications such as for detecting rotten, injured or damaged parts of a wide variety of citrus.

    The laser interferometer space antenna (LISA) is a future space-based interferometric gravitational-wave detector consisting of three spacecraft in a triangular configuration. The interferometric measurements of path length changes between satellites will be performed on optical benches in the satellites. Angular misalignments of the interfering beams couple into the length measurement and represent a significant noise source. Imaging systems will be used to reduce this tilt-to-length coupling. We designed and constructed an optical test bed to experimentally investigate tilt-to-length coupling. It consists of two separate structures, a minimal optical bench and a telescope simulator. The minimal optical bench comprises the science interferometer where the local laser is interfered with light from a remote spacecraft. In our experiment, a simulated version of this received beam is generated on the telescope simulator. The telescope simulator provides a tilting beam, a reference interferometer and an additional static beam as a phase reference. The tilting beam can either be a flat-top beam or a Gaussian beam. We avoid tilt-to-length coupling in the reference interferometer by using a small photo diode placed at an image of the beam rotation point. We show that the test bed is operational with an initial measurement of tilt-to-length coupling without imaging systems. Furthermore, we show the design of two different imaging systems whose performance will be investigated in future experiments. (paper)

    In radiography there is generally a conflict between the best image quality and the lowest possible patient dose. A proven method of dosimetry is the simulation of radiation transport in virtual human models (i.e. phantoms). However, while the resolution of these voxel models is adequate for most dosimetric purposes, they cannot provide the required organ fine structures necessary for the assessment of the imaging quality. The aim of this work is to develop hybrid/dual-lattice voxel models (called also phantoms) as well as simulation methods by which patient dose and image quality for typical radiographic procedures can be determined. The results will provide a basis to investigate by means of simulations the relationships between patient dose and image quality for various imaging parameters and develop methods for their optimization. A hybrid model, based on NURBS (Non Linear Uniform Rational B-Spline) and PM (Polygon Mesh) surfaces, was constructed from an existing voxel model of a female patient. The organs of the hybrid model can be then scaled and deformed in a non-uniform way i.e. organ by organ; they can be, thus, adapted to patient characteristics without losing their anatomical realism. Furthermore, the left lobe of the lung was substituted by a high resolution lung voxel model, resulting in a dual-lattice geometry model. "Dual lattice" means in this context the combination of voxel models with different resolution. Monte Carlo simulations of radiographic imaging were performed with the code EGS4nrc, modified such as to perform dual lattice transport. Results are presented for a thorax examination.

    Large-scale public infrastructure projects have featured in China's modernization course since the early 1980s. During the early stages of China's rapid economic development, public attention focused on the economic and social impact of high-profile construction projects. In recent years, however, we have seen a shift in public concern toward the environmental and ecological effects of such projects, and today governments are required to provide valid environmental impact assessments prior to allowing large-scale construction. The official requirement for the monitoring of environmental conditions has led to an increased number of debates in recent years regarding the effectiveness of Environmental Impact Assessments (EIAs) and Governmental Environmental Audits (GEAs) as environmental safeguards in instances of large-scale construction. Although EIA and GEA are conducted by different institutions and have different goals and enforcement potential, these two practices can be closely related in terms of methodology. This article cites the construction of the Qinghai-Tibet Railway as an instance in which EIA and GEA offer complementary approaches to environmental impact management. This study concludes that the GEA approach can serve as an effective follow-up to the EIA and establishes that the EIA lays a base for conducting future GEAs. The relationship that emerges through a study of the Railway's construction calls for more deliberate institutional arrangements and cooperation if the two practices are to be used in concert to optimal effect.

    To identify the prevalence of body image dissatisfaction and associated factors among students in Salvador, Brazil. A cross-sectional study involving a random sample of 1,494 (852 girls and 642 boys) adolescents between 11 and 17 years of age who were students in the public schools in Salvador, Brazil. Participants completed the Body Shape Questionnaire and the Eating Attitudes Test-26. Body image was characterized as satisfactory or unsatisfactory. We obtained demographic, anthropometric and economic information and information regarding the stage of maturation, self-perception of body weight, and consumption of sweetened beverages and diet soft drinks. To identify associated factors we used Poisson regression analysis. Body image dissatisfaction was present in 19.5% of the adolescents, with a prevalence of 26.6% among the girls and 10% among the boys. Independent of sex, the prevalence of body image dissatisfaction was higher among adolescents who were overweight or obese (girls, PR: 1.38, CI: 1.09-1.73 and boys, PR: 2.26, CI: 1.08-4.75), higher among those who perceived themselves as fat (girls, PR: 2.85, CI: 2.07-3.93 and boys, PR: 3.17, CI: 1.39-7.23), and higher among those who had negative attitudes toward eating (girls, PR: 2.42, CI: 1.91-3.08 and boys, PR: 4.67, CI: 2.85-7.63).. A reduction in body image dissatisfaction was only identified among underweight girls (PR: 0.12, CI: 0.03-0.49). A high occurrence of body image dissatisfaction was observed among the adolescents, and biological and behavioral factors were associated with this dissatisfaction.

  5. Information security system based on virtual-optics imaging methodology and public key infrastructure

    Science.gov (United States)

    Peng, Xiang; Zhang, Peng; Cai, Lilong

    In this paper, we present a virtual-optical based information security system model with the aid of public-key-infrastructure (PKI) techniques. The proposed model employs a hybrid architecture in which our previously published encryption algorithm based on virtual-optics imaging methodology (VOIM) can be used to encipher and decipher data while an asymmetric algorithm, for example RSA, is applied for enciphering and deciphering the session key(s). For an asymmetric system, given an encryption key, it is computationally infeasible to determine the decryption key and vice versa. The whole information security model is run under the framework of PKI, which is on basis of public-key cryptography and digital signatures. This PKI-based VOIM security approach has additional features like confidentiality, authentication, and integrity for the purpose of data encryption under the environment of network.

    In this paper, a novel image encryption system with fingerprint used as a secret key is proposed based on the phase retrieval algorithm and RSA public key algorithm. In the system, the encryption keys include the fingerprint and the public key of RSA algorithm, while the decryption keys are the fingerprint and the private key of RSA algorithm. If the users share the fingerprint, then the system will meet the basic agreement of asymmetric cryptography. The system is also applicable for the information authentication. The fingerprint as secret key is used in both the encryption and decryption processes so that the receiver can identify the authenticity of the ciphertext by using the fingerprint in decryption process. Finally, the simulation results show the validity of the encryption scheme and the high robustness against attacks based on the phase retrieval technique.

    One objective for risk communication is to improve the understanding of public values and concerns. This paper examined the perceptions of nuclear power plant engineers of an electric power company, about public values and concerns regarding nuclear power generation (image of public opinion), and compared them with actual public opinion. The image of public opinion was surveyed by questionnaire method. In the questionnaire, the subjects were asked to estimate the most preferred answer given to questions posed to the Japanese public. For some questions, subjects were asked to estimate the percentage of Japanese who selected a certain answer for a question or the distribution of the answers. The results showed: (1) Nuclear power plant engineers correctly recognized the existence of high anxiety in the public's mind concerning nuclear power generation. (2) Engineers were apt to underestimate the percentage of Japanese who think nuclear power generation is useful in our society. (3) The majority of Japanese assume that when nuclear power plant accidents occur radioactive leakage is so severe that it affects the health of inhabitants. However, the engineers were apt to estimate that the majority of Japanese think radioactive leakage is not so severe. (4) Engineers correctly recognized that the majority of Japanese think it is a realistic option to use the nuclear power generation. However, they incorrectly estimated that only 40% of Japanese think it is a realistic option to use the nuclear power generation when in fact 67% think so. These gaps between public opinion and the image of public opinion by the engineers were classified into two groups, one that stems from the cognitive bias when people estimate public opinion and one that is inherent in the engineers of nuclear power plants.

    Simultaneous PET–MR acquisition reduces the possibility of registration mismatch between the two modalities. This facilitates the application of techniques, either during reconstruction or post-reconstruction, that aim to improve the PET resolution by utilising structural information provided by MR. However, in order to validate such methods for brain PET–MR studies it is desirable to evaluate the performance using data where the ground truth is known. In this work, we present a framework for the production of datasets where simulations of both the PET and MR, based on real data, are generated such that reconstruction and post-reconstruction approaches can be fairly compared. -- Highlights: • A framework for simulating realistic brain PET–MR images is proposed. • The imaging data created is formed from real acquisitions. • Partial volume correction techniques can be fairly compared using this framework

  11. 2D and 3D GPR imaging of structural ceilings in historic and existing constructions

    Science.gov (United States)

    Colla, Camilla

    2014-05-01

    GPR applications in civil engineering are to date quite diversified. With respect to civil constructions and monumental buildings, detection of voids, cavities, layering in structural elements, variation of geometry, of moisture content, of materials, areas of decay, defects, cracks have been reported in timber, concrete and masonry elements. Nonetheless, many more fields of investigation remain unexplored. This contribution gives an account of a variety of examples of structural ceilings investigation by GPR radar in reflection mode, either as 2D or 3D data acquisition and visualisation. Ceilings have a pre-eminent role in buildings as they contribute to a good structural behaviour of the construction. Primarily, the following functions can be listed for ceilings: a) they carry vertical dead and live loads on floors and distribute such loads to the vertical walls; b) they oppose to external horizontal forces such as wind loads and earthquakes helping to transfer such forces from the loaded element to the other walls; c) they contribute to create the box skeleton and behaviour of a building, connecting the different load bearing walls and reducing the slenderness and flexural instability of such walls. Therefore, knowing how ceilings are made in specific buildings is of paramount importance for architects and structural engineers. According to the type of building and age of construction, ceilings may present very different solutions and materials. Moreover, in existing constructions, ceilings may have been substituted, modified or strengthened due to material decay or to change of use of the building. These alterations may often go unrecorded in technical documentation or technical drawings may be unavailable. In many cases, the position, orientation and number of the load carrying elements in ceilings may be hidden or not be in sight, due for example to the presence of false ceilings or to technical plants. GPR radar can constitute a very useful tool for

    The excised rat kidney slices were investigated using a simplified diffraction-enhanced imaging (DEI) configuration with only two crystals: the first one working as monochromator and the second one working as analyzer in the Bragg geometry that was developed at Beijing Synchrotron Radiation Facility (BSRF). Many fine anatomic structures of the sliced rat kidneys with thickness of 2mm and 120{mu}m can be distinguished clearly in the DEI images that were obtained at the shoulder of a rocking curve. The authors would like to emphasize that the thick and thin slices DEI provides very different images; in the thick sample only the structure with the big density gradient or that near the surface where X-ray comes out can be distinguished, while in the thin ones some fine structures, which can not be distinguished at the thick sample under the same condition, can be seen very clearly. The reason related with the counteraction of {delta}(x,y,z) gradient in the integral process along the X-ray path inside the thick sample is discussed.

    Digital radiographic imaging is increasing in veterinary practice. The use of radiation demands responsibility to maintain high image quality. Low doses are necessary because workers are requested to restrain the animal. Optimizing digital systems is necessary to avoid unnecessary exposure, causing the phenomenon known as dose creep. Homogeneous phantoms are widely used to optimize image quality and dose. We developed an automatic computational methodology to classify and quantify tissues (i.e., lung tissue, adipose tissue, muscle tissue, and bone) in canine chest computed tomography exams. The thickness of each tissue was converted to simulator materials (i.e., Lucite, aluminum, and air). Dogs were separated into groups of 20 animals each according to weight. Mean weights were 6.5 ± 2.0 kg, 15.0 ± 5.0 kg, 32.0 ± 5.5 kg, and 50.0 ± 12.0 kg, for the small, medium, large, and giant groups, respectively. The one-way analysis of variance revealed significant differences in all simulator material thicknesses (p optimize veterinary X-ray procedures.

    An automatic photographic system of the after-glow colour images (AGCI), which give very useful information related to crystal defects and impurities in white inorganic materials, has been developed. The present system consists of a combination of a photographic part installed in a dark bag with a control personal computer through an interface board. Thus, the photographic procedure of the successive and clear AGCIs could be accomplished from the direct contact of a colour film with an X-rays irradiated rock slices for desired exposure periods and interval times. By using this system, some AGCIs of ammonite fossil showed interesting changes of orange patterns due to structural fossil calcite. (author)

  16. Publics in the making: mediating different methods of engagement and the publics these construct : commentary on: "Technologies of democracy: experiments and demonstrations".

    Science.gov (United States)

    2011-12-01

    The potential for public engagement to democratise science has come under increasing scrutiny amid concerns that conflicting motivations have led to confusion about what engagement means to those who mediate science and publics. This raises important yet relatively unexplored questions regarding how publics are constituted by different forms of engagement used by intermediary scholars and other actors. It is possible to identify at least two possible 'rationalities of mediation' that mobilise different versions of the public and the roles they are assumed to play, as 'citizens' or 'users', in discussions around technology. However, combinations of rationalities are found in practice and these have significant implications for the 'new' scientific democracy.

    Full Text Available The paper presents the analysis of the II Underground Line construction’s impact on the Warsaw Scarp with the use of the electrical resistivity imaging (ERI, also known as the electrical resistivity tomography and further total station position measurements.The underground passes under the scarp perpendicular in the area of Dynasy Street 6, in Down-town district.The electrical resistivity imaging was performed for recognition of the geological structure and a potential land slide surface or zone.The gradient system was used during the prospection. In these analyses, the longitudinal section was 40 m long, and the depth of survey amounted to 6 m. In the case of the 200 m long transverse section, the resulted depth of survey was 30 m.The geophysical image of the longitudinal section,does not contain loosening soil zones,which could indicates lip surface.Next, total station measurements, which were tied to the archival geodetic observations’ results, were carried out. The aim of the measurements was to verify the activity of the horizontal and vertical displacements. The TBM excavation process led to summary vertical displacements up to approx. 24 mm and horizontal displacements amounting to approx. 13 mm. To sum up, the current land surveys reveals minor under ground line’ s construction impact on the scarp displacement. Nevertheless, the sensitive urban environment requires further monitoring, especially that the operation loads can result in displacement rate change.

    A decision-making framework for image-guided radiotherapy (IGRT) is being developed using a Bayesian Network (BN) to graphically describe, and probabilistically quantify, the many interacting factors that are involved in this complex clinical process. Outputs of the BN will provide decision-support for radiation therapists to assist them to make correct inferences relating to the likelihood of treatment delivery accuracy for a given image-guided set-up correction. The framework is being developed as a dynamic object-oriented BN, allowing for complex modelling with specific subregions, as well as representation of the sequential decision-making and belief updating associated with IGRT. A prototype graphic structure for the BN was developed by analysing IGRT practices at a local radiotherapy department and incorporating results obtained from a literature review. Clinical stakeholders reviewed the BN to validate its structure. The BN consists of a sub-network for evaluating the accuracy of IGRT practices and technology. The directed acyclic graph (DAG) contains nodes and directional arcs representing the causal relationship between the many interacting factors such as tumour site and its associated critical organs, technology and technique, and inter-user variability. The BN was extended to support on-line and off-line decision-making with respect to treatment plan compliance. Following conceptualisation of the framework, the BN will be quantified. It is anticipated that the finalised decision-making framework will provide a foundation to develop better decision-support strategies and automated correction algorithms for IGRT.

    2008-12-01

    Questions of diversity and multiculturalism are at the heart of many discussions on European supranational identity within contemporary anthropology, sociology, cultural studies, linguistics and so on. Since we are living in a period marked by the economic and political changes which emerged after European unification, a call for a new analysis of heterogeneity, cultural difference and issues of belonging is not surprising. This call has been fuelled by the European Union's concern with "culture" as one of the main driving forces for constructing "European identity". While the official European policy describes European culture as common to all Europeans, Europe is also-seen as representing "unity in diversity". By analysing contemporary European MEDIA policies and programs this article attempts to contribute to a small but growing body of work that explores what role "language" and "visual images" play in the process of constructing European culture and supranational European identity. More specifically, the article explores the complex articulation of language and culture in order to analyse supranational imaginary of European identity as it is expressed through the simple slogan "Europe: unity in diversity". We initially grounded our interest in the politics of identity within the European Union within theoretical frameworks of "power and knowledge" and "identity and subjectivity". We consider contemporary debates in social sciences and humanities over the concepts of language", "culture" and "identity" as inseparable from each other (Ahmed 2000; Brah 1996, 2000; Butler 1993, Derrida 1981; Gilroy 2004; Laclau 1990). Cultural and postcolonial studies theorists (e.g. Brah 1996; Bhabha 1994; Hall 1992, 1996, among others) argue that concepts of "culture" and "identity" signify a historically variable nexus of social meanings. That is to say, "culture" and "identity" are discursive articulations. According to this view, "culture" and "identity" are not separate

    We report on the set-up and performance of a dilution-refrigerator based spectroscopic imaging scanning tunneling microscope. It operates at temperatures below 10 mK and in magnetic fields up to 14T. The system allows for sample transfer and in situ cleavage. We present first-results demonstrating atomic resolution and the multi-gap structure of the superconducting gap of NbSe(2) at base temperature. To determine the energy resolution of our system we have measured a normal metal/vacuum/superconductor tunneling junction consisting of an aluminum tip on a gold sample. Our system allows for continuous measurements at base temperature on time scales of up to ≈170 h.

    A proximity focusing Cherenkov imager called CHERCAM, has been built for the charge measurement of nuclear cosmic rays with the CREAM instrument. It consists of a silica aerogel radiator plane across from a detector plane equipped with 1,600 1'' diameter photomultipliers. The two planes are separated by a ring expansion gap. The Cherenkov light yield is proportional to the charge squared of the incident particle. The expected relative light collection accuracy is in the few percents range. It leads to an expected single element separation over the range of nuclear charge Z of main interest 1 {<=} Z{approx}<26. CHERCAM is designed to fly with the CREAM balloon experiment. The design of the instrument and the implemented technical solutions allowing its safe operation in high altitude conditions (radiations, low pressure, cold) are presented.

    Full Text Available In global environment, understanding and managing multiculturalism mean recognizing similarities and differences among various cultures and use this cultural diversity to achieve one’s goal. Therefore, it is important to study the impact of cultural contrast upon some practical aspects such as: language; method of communication; cultural as well as management cultures. Culture influences the way in which people interact with one method and has direct impact upon communication patterns. If communication patterns are influenced by culture differences, it is important for public relations managers to be aware of individual behavior. The myth and reality of the Indonesian culture in its unique pluralistic characteristics known as “Bhinneka Tunggal Ika” (Unity through Diversity represent the Asian society. Dreaming upon the traditional Asian and uniquely Indonesian cultural values, the Indonesian managers of 2001 appear to be successfully working within the cultural boundaries of Asian and Western corporate values. This paper discusses the relationship between cultural and Public Relations practice in Indonesia embracing the trend of 2001—focused on image and possible cultural sensitivity building by means of blending the Asian and Western values to create a synergeticorganizations in practicing Public Relations At 21st centuries.

Participants 2022 medical imaging tests were extracted from the radiology information system in February and March of 2014. MRI and ultrasound examinations were excluded. Primary and secondary outcome measures Five outcomes were set independently by at least two researchers according to four guidelines: (1) appropriate; (2) inappropriate; (3) inappropriate due to repetition, if the timing to carry out next diagnostic tests was incorrect according to guidelines; (4) not adequately justified, if the referral form did not include enough clinical information to allow us to understand the patient’s clinical condition; and (5) not included in the guidelines, if the referral could not be matched to a clinical scenario described in the guidelines. We estimated the prevalence of the five categories according to relevant clinical and sociodemographic variables and the effective radiation dose and costs for each category. Results Approximately half of the imaging tests were deemed as appropriate (967, 47.8%) while one-third (634, 31.4%) were considered inappropriate. 19.6% of the effective dose and 25.2% of the cost were associated with inappropriate tests. Women were less likely than men to have an imaging test classified as appropriate (adjusted OR 0.70,95% CI 0.57 to 0.86). Imaging tests requested by general practitioners were less likely to be considered appropriate than those requested by central services (adjusted OR 0.60, 95% CI 0.38 to 0.93). Mammography and CT were more likely to be appropriate than conventional X-rays. Conclusion There was a significant frequency of inappropriateness, which resulted in a high percentage of associated effective radiation dose. Percentage of inappropriateness depends on

In this work, raw data were obtained through measurements in selected points on a square regions in order to detect specific organic / inorganic compounds on biological samples. Gold nano stars samples were prepared and coated with membrane markers (CD 10+ and CD 19+) and diluted in leukemic B lymphocytes. Each data block was evaluated independently by the method of principal component analysis (Pca) in order to find representative dimensionless values (Cp) for each Raman spectrum in a specific coordinate. Each Cp was normalized in a range of 0-255 in order to generate a representative image of 8 bits of the region under study. Data acquisition was performed with Raman microscopy system Renishaw in Via in the range of 550 to 1700 cm-1 with a 785 nm laser source, with a power of 17 m W and 15 s of exposure time were used for each spectrum. In preliminary results could detect the presence of molecular markers CD 10+ and CD 19+ with gold nano stars and discrimination between both markers. The results suggest conducting studies with specific concentrations organic and inorganic materials. (Author)

    Full Text Available The focus of this article are interesting rarities from the collection of the State Hermitage Museum - swords of the 17th-18th centuries with inscriptions in Greek and Slavonic, with images of Christian saints inlaid in gold. The authors offer the general characteristics of 17 exemplars of this kind of arms which are divided into several groups according to the shape of the hilt. A brief overview of the relatively few publications on this subject includes articles by Vasilii Prokhorov (1877; data from the Index of the Medieval Department of the Imperial Hermitage published by Nikodim Kondakov (1891, a catalogue of Count Sergei Sheremetev's collection of arms compiled by Eduard Lenz (1895, and a monograph by E. Astvatsaturian on Turkish arms from the collection of the State Historical Museum (2002. The authors pay special attention to the description and analysis of two swords from the Hermit- age collection. One of them belonged to Count Michail Miloradovich, and was presented to him in 1807 from the city of Bucharest. The second sword came to the Hermitage after the Bolshevik Revolution from the Marble Palace, the residency of the Grand Dukes Konstantinovichi. Besides the traditional inscriptions and images of the Virgin with Child crowned by angels, the blade bears a unique image of Byzantine Emperor Nikephoros Phokas blessed by Jesus Christ with both hands. There are also two cartouches with quotations from Psalms in Greek. The extremely rich décor of this sword and the unique depiction of the Byzantine Emperor leave no doubt that they were made on a special order. The authors connect the sword to the Greek Project initiated by the Russian Empress Catherine the Great. The main idea of the project was a restoration of the Byzantine Empire with Constantinople-Istanbul as its capital, where Grand Duke Konstantin, Catherine the Great's grandchild, would be ascended to the throne. This article is a preliminary publication of a project in process

    The size distribution of aggregates has direct and important effects on fundamental properties of construction materials such as workability, strength and durability. The size distribution of aggregates from construction and demolition waste (C&D) is one of the parameters which determine the degree of recyclability and therefore the quality of such materials. Unfortunately, standard methods like sieving or laser diffraction can be either very time consuming (sieving) or possible only in laboratory conditions (laser diffraction). As an alternative we propose and evaluate the use of image analysis to estimate the size distribution of aggregates from C&D in a fast yet accurate manner. The effectiveness of the procedure was tested on aggregates generated by an existing C&D mechanical treatment plant. Experimental comparison with manual sieving showed agreement in the range 81-85%. The proposed technique demonstrated potential for being used on on-line systems within mechanical treatment plants of C&D. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Lakhujani, Vijay; Badapanda, Chandan

    2017-06-01

    QIIME (Quantitative Insights Into Microbial Ecology) is one of the most popular open-source bioinformatics suite for performing metagenome, 16S rRNA amplicon and Internal Transcribed Spacer (ITS) data analysis. Although, it is very comprehensive and powerful tool, it lacks a method to provide publication ready taxonomic pie charts. The script plot_taxa_summary . py bundled with QIIME generate a html file and a folder containing taxonomic pie chart and legend as separate images. The images have randomly generated alphanumeric names. Therefore, it is difficult to associate the pie chart with the legend and the corresponding sample identifier. Even if the option to have the legend within the html file is selected while executing plot_taxa_summary . py , it is very tedious to crop a complete image (having both the pie chart and the legend) due to unequal image sizes. It requires a lot of time to manually prepare the pie charts for multiple samples for publication purpose. Moreover, there are chances of error while identifying the pie chart and legend pair due to random alphanumeric names of the images. To bypass all these bottlenecks and make this process efficient, we have developed a python based program, prepare_taxa_charts . py , to automate the renaming, cropping and merging of taxonomic pie chart and corresponding legend image into a single, good quality publication ready image. This program not only augments the functionality of plot_taxa_summary . py but is also very fast in terms of CPU time and user friendly.

  2. Public financing of research projects in Poland – its image and consequences?

    Full Text Available Both the size of appropriation as well as their distribution have had a profound impact on the shape and activities of the science sector. The creation of a fair system of distribution of public resources to research that will also facilitate the effective implementation of the pursued scientific policy goals represents a major challenge. The issue of the determination of the right proportions of individual distribution channels remains critical. Despite this task being the responsibility of the State, establishing cooperation in this respect with the scientific community is desirable. The implementation of solutions that raise the concerns of scientists leads to system instability and reduced effectiveness which is manifest among others in a lower level of indicators of scientific excellence and innovation in the country. These observations are pertinent to Poland where the manner in which scientific institutes operate were changed under the 2009–2011 reform. A neoliberal operating model based on competitiveness and rewarding of top rated scientific establishments and scientists was implemented. In light of these facts, the initiation of research that will provide information on how the implemented changes are perceived by the scientific community seems to be appropriate. The aim of this article is in particlar presenting how the project model of financing laid down under the reform is perceived and what kind of image has been shaped among Polish scientists. In order to gain a comprehensive picture of the situation, both the rational and emotional image was subject to analysis. The conclusions regarding the perception of the project model were drawn on the basis of empirical materials collected in a qualitative study the specifics of which will be presented in the chapter on methodology. Prior to that, the author discusses the basic models for the distribution of state support for science and characterises the most salient features of the

  3. Monitoring Urban Tree Cover Using Object-Based Image Analysis and Public Domain Remotely Sensed Data

    Full Text Available Urban forest ecosystems provide a range of social and ecological services, but due to the heterogeneity of these canopies their spatial extent is difficult to quantify and monitor. Traditional per-pixel classification methods have been used to map urban canopies, however, such techniques are not generally appropriate for assessing these highly variable landscapes. Landsat imagery has historically been used for per-pixel driven land use/land cover (LULC classifications, but the spatial resolution limits our ability to map small urban features. In such cases, hyperspatial resolution imagery such as aerial or satellite imagery with a resolution of 1 meter or below is preferred. Object-based image analysis (OBIA allows for use of additional variables such as texture, shape, context, and other cognitive information provided by the image analyst to segment and classify image features, and thus, improve classifications. As part of this research we created LULC classifications for a pilot study area in Seattle, WA, USA, using OBIA techniques and freely available public aerial photography. We analyzed the differences in accuracies which can be achieved with OBIA using multispectral and true-color imagery. We also compared our results to a satellite based OBIA LULC and discussed the implications of per-pixel driven vs. OBIA-driven field sampling campaigns. We demonstrated that the OBIA approach can generate good and repeatable LULC classifications suitable for tree cover assessment in urban areas. Another important finding is that spectral content appeared to be more important than spatial detail of hyperspatial data when it comes to an OBIA-driven LULC.

    Scanning probe microscopy (SPM) such as atomic force microscopy (AFM) is widely known for high-resolution imaging of surface structures and nanolithography in two dimension (2D), which provides important physical insights in surface science and material science. This work reports a new algorithm to enable construction and display of layer-by-layer 3D structures from SPM images. The algorithm enables alignment of SPM images acquired during layer-by-layer deposition, removal of redundant features, and faithfully constructs the deposited 3D structures. The display uses a "see-through" strategy to enable the structure of each layer to be visible. The results demonstrate high spatial accuracy as well as algorithm versatility; users can set parameters for reconstruction and display as per image quality and research needs. To the best of our knowledge, this method represents the first report to enable SPM technology for 3D imaging construction and display. The detailed algorithm is provided to facilitate usage of the same approach in any SPM software. These new capabilities support wide applications of SPM that require 3D image reconstruction and display, such as 3D nanoprinting, and 3D additive and subtractive manufacturing and imaging.

    2016-07-01

    Full Text Available Suitable and sustainable buildings have increased demands for design and for the transfer of design requirements to realization. That causes an increase of risk connected with the differences between planned and real parameters of the buildings. This article will outline the main theme comparison between DBB and DB projects concerning contractor’s risk management level. This comparative analysis explains, using the RIPRAN method, the hidden risks in each type of delivery method. The comparison identifies numerous contractual topics and risks included in both and gives deeper insight into risk management, both for the contracting party and also for public procurement. Applying risk analysis strategies and tools to the process will help decision-makers evaluate and select the suitable delivery method consistently and defensibly. This paper gives generic risk factors related to both project types. The results indicate risk factors with influence on the price, probability of occurrence and unfavourable impact on the project and help allocate risk level more properly in accordance with its high, middle or low probable impact. Public investment is a significant part of the public budget, the application of design-build can help with the reduction of corruption, and the public sector can benefit from the usage of DB projects to help eliminate the mistakes made by contracting authorities.

    The design and construction of wide FOV imaging polarimeters for use in atmospheric remote sensing requires significant attention to the prevention of artificial polarization induced by the optical elements. Surface, coatings, and angles of incidence throughout the system must be carefully designed in order to minimize these artifacts because the remaining instrumental bias polarization is the main factor which drives the final polarimetric accuracy of the system. In this work, we present a detailed evaluation and analysis to explore the possibility of retrieving the initial polarization state of the light traveling through a generic system that has inherent instrumental polarization. Our case is a wide FOV lens and a splitter device. In particular, we chose as splitter device a Philips-type prism, because it is able to divide the signal in 3 independent channels that could be simultaneously analyze to retrieve the three first elements of the Stoke vector (in atmospheric applications the elliptical polarization can be neglected [1]). The Philips-type configuration is a versatile, compact and robust prism device that is typically used in three color camera systems. It has been used in some commercial polarimetric cameras which do not claim high accuracy polarization measurements [2]. With this work, we address the accuracy of our polarization inversion and measurements made with the Philips-type beam divider.

  9. The Use of Personal Value Estimations to Select Images for Preservation in Public Library Digital Community Collections

    Directory of Open Access Journals (Sweden)

    Andrea Copeland

    2014-05-01

    Full Text Available A considerable amount of information, particularly in image form, is shared on the web through social networking sites. If any of this content is worthy of preservation, who decides what is to be preserved and based on what criteria. This paper explores the potential for public libraries to assume this role of community digital repositories through the creation of digital collections. Thirty public library users and thirty librarians were solicited from the Indianapolis metropolitan area to evaluate five images selected from Flickr in terms of their value to public library digital collections and their worthiness of long-term preservation. Using a seven-point Likert scale, participants assigned a value to each image in terms of its importance to self, family and society. Participants were then asked to explain the reasoning behind their valuations. Public library users and librarians had similar value estimations of the images in the study. This is perhaps the most significant finding of the study, given the importance of collaboration and forming partnerships for building and sustaining community collections and archives.

    Regulations intended to reduce the number of accidents at nuclear plants and the discharge of sulfur and particulate wastes at coal-fired power plants have become an important cause of construction cost escalation. Measuring the costs of these regulatory interventions is a difficult research task. The three-unit Bruce Mansfield coal-fired plant and the two-unit Beaver Valley nuclear power station located in Shippingport, Pennsylvania, provide a unique opportunity for a case study of the costs of regulation in the construction of both kinds of plants. The units of each plant were built sequentially over a period of intensifying regulation. The method used to measure the costs of public safety regulation in the construction of each kind of plant is to determine the connections between the issuances of the regulatory agencies (EPA and NRC) and cost escalations of succeeding units. The small cost escalations of the Mansfield 3 unit, in comparison to the massive costs of the Beaver Valley 2 unit, suggest that the design and construction of new coal-fired plants are not disrupted by regulatory interventions nearly as extensively as are nuclear units. Certain technical features of Beaver Valley 2, especially its small size and a design that is identical to the first unit's, further contribute to its cost escalations

    The Single Stimulus (SS) method is often chosen to collect subjective data testing no-reference objective metrics, as it is straightforward to implement and well standardized. At the same time, it exhibits some drawbacks; spread between different assessors is relatively large, and the measured ratings depend on the quality range spanned by the test samples, hence the results from different experiments cannot easily be merged . The Quality Ruler (QR) method has been proposed to overcome these inconveniences. This paper compares the performance of the SS and QR method for pictures impaired by Gaussian blur. The research goal is, on one hand, to analyze the advantages and disadvantages of both methods for quality assessment and, on the other, to make quality data of blur impaired images publicly available. The obtained results show that the confidence intervals of the QR scores are narrower than those of the SS scores. This indicates that the QR method enhances consistency across assessors. Moreover, QR scores exhibit a higher linear correlation with the distortion applied. In summary, for the purpose of building datasets of subjective quality, the QR approach seems promising from the viewpoint of both consistency and repeatability.

    The need to create in the Argentine public opinion new positives symbols and images on nuclear energy and on the benefits of its peaceful applications, is al present so important as the development of new technical tools to improve the nuclear industry. These positives symbols and imagines on nuclear energy must be created in the framework of a joint strategy of all the country's nuclear institutions as well as other public organizations, in view of the new nuclear plan recently announced. This joint strategy will permit to create not only the new positives symbols and images in the public opinion, but also to obtain the support of the mass media and new spaces for negotiation in the national, provincial and municipal levels.

    Lee, Joseph G. L.; Dworkin, Shari L.

    2014-01-01

    Research shows that constraining aspects of male gender norms negatively influence both women’s and men’s health. Messaging that draws on norms of masculinity in health programming has been shown to improve both women’s and men’s health, but some types of public health messaging (e.g., Man Up Monday, a media campaign to prevent the spread of sexually transmitted infections) can reify harmful aspects of hegemonic masculinity that programs are working to change. We critically assess the deployment of hegemonic male norms in the Man Up Monday campaign. We draw on ethical paradigms in public health to challenge programs that reinforce harmful aspects of gender norms and suggest the use of gender-transformative interventions that challenge constraining masculine norms and have been shown to have a positive effect on health behaviors.

    This article is the product of research that analyzed the work of bus drivers of a public transportation company that is considered a benchmark reference in its field of operations, in which it strives to achieve operating excellence. Within this context, the authors sought to understand how such a company has managed to maintain a policy that is capable of reconciling quality public transport while also providing working conditions compatible with the professional development, comfort and health of its workers. Ergonomic work analysis and activity analysis were the guiding elements used in this study. Initial analyses indicate that the activity of drivers includes serving a population and providing mobility for it, which depends on driving the vehicle itself and on relationships with colleagues, users, pedestrians, drivers and others.

  18. The effect of public or private structures in wastewater treatment on the conditions for the design, construction and operation of wastewater treatment plants.

    2004-01-01

    Organised in public or private structures, wastewater services have to cope with different framework conditions as regards planning, construction, financing and operation. This leads quite often to different modes of management. In recent years there has been a push for privatisation on the water sector in general, the reasons for which are manifold, ranging from access to external know-how and capital to synergistic effects through integration of wastewater treatment into other tasks of similar or equal nature. Discussed are various models of public/private partnership (PPP) in wastewater treatment, encompassing for example the delegation of partial tasks or even the proportional or entire transfer of ownership of treatment facilities to private third parties. Decisive for high performance and efficiency is not the legal or organisational form, but rather the clear and unmistakable definition of tasks which are to be assigned to the different parties, customers and all other partners involved, as well as of clear-cut interfaces. On account of the (of course legitimate) profit-oriented perspective of the private sector, some decision-making processes in relation to project implementation (design and construction) and to operational aspects will differ from those typically found on the public sector. This does apply to decisions on investments, financing and on technical solutions too. On the other hand, core competencies in wastewater treatment should not be outsourced, but remain the public bodies' responsibility, even with 'far-reaching' privatisation models. Such core competencies are all efforts geared to sustainable wastewater treatment as life-supporting provision for the future or as contribution to the protection of health and the environment and to the development of infrastructure. Major areas of wastewater treatment and other related tasks are reviewed. The paper concludes with a list of questions on the issue of outsourcing.

    Poor health outcomes from insufficient physical activity (PA) are a persistent public health issue. Public transit is often promoted for positive influence on PA. Although there is cross-sectional evidence that transit users have higher PA levels, this may be coincidental or shifted from activities such as recreational walking. We use a quasi-experimental design to test if light rail transit (LRT) generated new PA in a neighborhood of Salt Lake City, Utah, USA. Participants (n=536) wore Global Positioning System (GPS) receivers and accelerometers before (2012) and after (2013) LRT construction. We test within-person differences in individuals' PA time based on changes in transit usage pre- versus post-intervention. We map transit-related PA to detect spatial clustering of PA around the new transit stops. We analyze within-person differences in PA time based on daily transit use and estimate the effect of daily transit use on PA time controlling for socio-demographic variables. Results suggest that transit use directly generates new PA that is not shifted from other PA. This supports the public health benefits from new high quality public transit such as LRT.

    To evaluate the role of three-dimensional constructive interference in steady state (3D-CISS) sequences and phase-contrast magnetic resonance imaging (PC-MRI) in patients with arrested hydrocephalus. A prospective study of 20 patients with arrested hydrocephalus was carried out. All patients underwent PC-MRI and 3D-CISS for assessment of the aqueduct. Axial (through-plane), sagittal (in-plane) PC-MRI, and sagittal 3D-CISS were applied to assess the cerebral aqueduct and the spontaneous third ventriculostomy if present. Aqueductal patency was graded using 3D-CISS and PC-MRI. Quantitative analysis of flow through the aqueduct was performed using PC-MRI. The causes of obstruction were aqueductal obstruction in 75% (n = 15), third ventricular obstruction in 5% (n = 1), and fourth ventricular obstruction in 20% (n = 4). The cause of arrest of hydrocephalus was spontaneous third ventriculostomy in 65% (n = 13), endoscopic third ventriculostomy in 10% (n = 2), and ventriculoperitoneal shunt in 5% (n = 1), and no cause could be detected in 20% of patients (n = 4). There is a positive correlation (r = 0.80) and moderate agreement (κ = 0.509) of grading with PC-MRI and 3D-CISS sequences. The mean peak systolic velocity of cerebrospinal fluid was 1.86 ± 2.48 cm/second, the stroke volume was 6.43 ± 13.81 μL/cycle, and the mean flow was 0.21 ± 0.32 mL/minute. We concluded that 3D-CISS and PC-MRI are noninvasive sequences for diagnosis of the level and cause of arrested hydrocephalus. Copyright © 2016 Elsevier Inc. All rights reserved.

  1. Corporate Image and Public Health: An Analysis of the Philip Morris, Kraft, and Nestlé Websites

    Science.gov (United States)

    SMITH, ELIZABETH

    2012-01-01

    Companies need to maintain a good reputation to do business; however, companies in the infant formula, tobacco, and processed food industries have been identified as promoting disease. Such companies use their websites as a means of promulgating a positive public image, thereby potentially reducing the effectiveness of public health campaigns against the problems they perpetuate. The author examined documents from the websites of Philip Morris, Kraft, and Nestlé for issue framing and analyzed them using Benoit’s typology of corporate image repair strategies. All three companies defined the problems they were addressing strategically, minimizing their own responsibility and the consequences of their actions. They proposed solutions that were actions to be taken by others. They also associated themselves with public health organizations. Health advocates should recognize industry attempts to use relationships with health organizations as strategic image repair and reject industry efforts to position themselves as stakeholders in public health problems. Denormalizing industries that are disease vectors, not just their products, may be critical in realizing positive change. PMID:22420639

    We studied the brain activation patterns in two visual image processing tasks requiring judgements on object construction (FIT task) or object sameness (SAME task). Eight right-handed healthy human subjects (four women and four men) performed the two tasks in a randomized block design while 5-mm, multislice functional images of the whole brain were acquired using a 4-tesla system using blood oxygenation dependent (BOLD) activation. Pairs of objects were picked randomly from a set of 25 oriented fragments of a square and presented to the subjects approximately every 5 sec. In the FIT task, subjects had to indicate, by pushing one of two buttons, whether the two fragments could match to form a perfect square, whereas in the SAME task they had to decide whether they were the same or not. In a control task, preceding and following each of the two tasks above, a single square was presented at the same rate and subjects pushed any of the two keys at random. Functional activation maps were constructed based on a combination of conservative criteria. The areas with activated pixels were identified using Talairach coordinates and anatomical landmarks, and the number of activated pixels was determined for each area. Altogether, 379 pixels were activated. The counts of activated pixels did not differ significantly between the two tasks or between the two genders. However, there were significantly more activated pixels in the left (n = 218) than the right side of the brain (n = 161). Of the 379 activated pixels, 371 were located in the cerebral cortex. The Talairach coordinates of these pixels were analyzed with respect to their overall distribution in the two tasks. These distributions differed significantly between the two tasks. With respect to individual dimensions, the two tasks differed significantly in the anterior--posterior and superior--inferior distributions but not in the left--right (including mediolateral, within the left or right side) distribution.

    A questionnaire survey about the public's image of radiation was performed after the Fukushima Daiichi nuclear power plant (FDNPP) accident. The survey was taken by general citizens (200 and 1,640 in Fukushima and 52 outside of Fukushima) and doctors (63 in Fukushima and 1,942 outside of Fukushima (53 in Oita, 44 in Sagamihara and 1,845 in Kitakyushu) in and outside of Fukushima and second year medical students in the University of Occupational and Environmental Health, Japan. The questionnaire surveys were performed during lectures about radiation. The response rates were 86% for the general citizens in Fukushima, 91% for the general citizens outside of Fukushima, 86% for doctors in Fukushima, 85% and 86% for doctors in Sagamihara and Oita, respectively. The questionnaire surveys were sent to clinics and hospitals in Fukushima where the general citizens answered with a response rate of 50%. When the questionnaire surveys were sent to clinics and hospitals in Kitakyushu, doctors answered, with a response rate of 17%. The percentages of anxiety about future radiation effects after the FDNPP accident were the highest among the general citizens (71.6% in Fukushima and 40.4% outside of Fukushima), in the middle among the doctors (30.2% in Fukushima and 26.2% outside of Fukushima) and the lowest among the medical students (12.2%). The doctors in Fukushima and the medical students were anxious about food and soil pollution. The general citizens and the detectors outside of Fukushima were anxious about health problems and food and soil pollution. We concluded that a high level of education about radiation decreased the anxiety about the radiation effects. It is important to spread knowledge about radiation. (author)

    The Final Environmental Impact Statement (FEIS) (Volume 1), was prepared by the Nuclear Regulatory Commission (NRC) in accordance with regulation 10 CFR Part 51, which implements the National Environmental Policy Act (NEPA), to assess the potential environmental impacts for licensing the construction and operation of a proposed gaseous centrifuge enrichment facility to be built in Claiborne Parish, Louisiana by Louisiana Energy Services, L.P. (LES). The proposed facility would have a production capacity of about 866 metric tons annually of up to 5 weight percent enriched UF 6 , using a proven centrifuge technology. Included in the assessment are co on, both normal operations and potential accidents (internal and external events), and the eventual decontamination and decommissioning of the site. In order to help assure that releases from the operation of the facility and potential impacts on the public are as low as reasonably achievable, an environmental monitoring program was developed by LES to detect significant changes in the background levels of uranium around the site. Other issues addressed include the purpose and need for the facility, the alternatives to the proposed action, potential disposition of the tails, the site selection process, and environmental justice. The NRC staff concludes that the facility can be constructed and operated with small and acceptable impacts on the public and the environment, and proposes to issue a license to the applicant, Louisiana Energy Services, to authorize construction and operation of the proposed facility. The letters in this Appendix have been divided into three sections. Section One contains letters to which the NRC responded by addressing specific comments. Section Two contains the letters that concerned the communities of Forest Grove and Center Springs. Section Three is composed of letters that required no response. These letters were generally in support of the facility

  7. Protection of third parties. The protection of third parties affected by building or plant construction permits under the public construction law, the emission control law, or the atomic energy law

    1993-01-01

    Building construction permits just like plant construction permits under the Federal Emission Control Act or the Atomic Energy Act are typical cases representing the administrative order with a dual effect, or an effect on third parties: decisions supporting the interests of the project owner always affect third parties. Third party protection therefore is a major topic of public construction law or the environmental protection law to be applied to industrial installations. Although actions brought by third parties have become something ordinary for the administrative courts, substantive third party protection continues to pose specific problems. The book in hand develops and explains a way out of the dilemma created by third party protection. The solutions presented are founded on a sound dogmatic basis and take into account the Federal Constitutional Court's rulings in matters of civil rights. The starting point adopted by the authors is the third party rights warranting protection, with the objective protection provided for by the law in general gaining effect as subjective rights as far as the protection is based on the civil rights of the constitution. The scope of protection affordable depends on the individual case and the reconciliation of terests of all parties concerned. The problem solutions set forth very extensively rely on the jurisdiction in matters of third party protection and on approaches published in the relevant literature, so that the book also may serve as a guide to current practice and a helpful source of reference for readers looking for information about the issue of third party protection.

    Full Text Available The issues related to the role of the family in the process of creating relationships with ill and disabled people are discussed in the article. All individuals posses concepts of the disabled that form their attitudes towards such people. The image of a disabled person is responsible for one’s attitude towards the handicapped. The family should create an environment where children observe and learn positive patterns of behaviour towards people with disabilities which, in turn, form the basis upon which children’s attitudes are shaped. The process of perception of other people is dependent on many factors – one of them is the family. The author draws attention to the issue of gender in disability. The term “disabled person” turns out to be gender neutral. Women with disabilities consider themselves to be treated as a “third sex”. The discrimination of disabled women results from a lack of sensitivity to the sex of the disabled. This points out the need to change the attitudes towards people with disabilities in early childhood as well as the necessity to pay more attention to the gender of disabled children. Sex becomes a matter which is forgotten, perhaps even becoming irrelevant. Women and their function are pushed into the background, which results in the gender-related stereotyping of their social roles, a more difficult way of career advancement (the so-called “glass ceiling effect”, lower wages for women working in the same positions as men, and the low participation of women in public life.

    The National Institutes of Health have placed significant emphasis on sharing of research data to support secondary research. Investigators have been encouraged to publish their clinical and imaging data as part of fulfilling their grant obligations. Realizing it was not sufficient to merely ask investigators to publish their collection of imaging and clinical data, the National Cancer Institute (NCI) created the open source National Biomedical Image Archive software package as a mechanism for centralized hosting of cancer related imaging. NCI has contracted with Washington University in Saint Louis to create The Cancer Imaging Archive (TCIA)-an open-source, open-access information resource to support research, development, and educational initiatives utilizing advanced medical imaging of cancer. In its first year of operation, TCIA accumulated 23 collections (3.3 million images). Operating and maintaining a high-availability image archive is a complex challenge involving varied archive-specific resources and driven by the needs of both image submitters and image consumers. Quality archives of any type (traditional library, PubMed, refereed journals) require management and customer service. This paper describes the management tasks and user support model for TCIA.

  11. LINGUISTIC FEATURES OF NATO’S MEDIA IMAGE (THE CASE STUDY OF BRITISH ONLINE PUBLICATIONS

    Directory of Open Access Journals (Sweden)

    Valuyskaya Olga Ruslanovna

    2014-12-01

    Full Text Available The paper investigates linguistic specific means of NATO's image making in online British leading newspapers. The case study involves news reports and analytical articles that represent explicit and implicit evaluation of the North Atlantic Treaty Organization. The investigation is based on the principles of the media linguistic approach and suggests the structural peculiarities of a media image that can be analyzed as a three-sided unit including positive, negative and neutral structural elements of image introduction into a media text. The NATO's image can be viewed as that of a geopolitical actor, creating its Natoland. Certain media topics are analyzed as creating positive and negative images of the NATO as a military organization. A finite list of positive and negative constituents to the Alliance's image is presented in the paper. It is assumed that the simplistic writer-reader model of interaction shapes certain elements of a media image that can be interpreted by a reader. The author distinguishes in the paper the principle constituents of an international organization in general, and the NATO in particular. Findings of the study demonstrate that the NATO's media image is interpreted by the readers as the conceptual entity of two key images: a peacemaker and a hawk that are restored on lexical and intertextual levels.

    Results of microvascular decompression (MVD) for trigeminal neuralgia (TN) and hemifacial spasm (HFS) may be improved by accurate preoperative assessment of neurovascular relationships at the root entry/exit zone (REZ). Constructive interference in steady state (CISS)-three-dimensional Fourier transformation (3DFT) magnetic resonance (MR) imaging was evaluated for visualizing the neurovascular relationships at the REZ. Fourteen patients with TN and eight patients with HFS underwent MR imaging using CISS-3DFT and 3D fast inflow with steady-state precession (FISP) sequences. Axial images of the cerebellopontine angle (CPA) obtained by the two sequences were reviewed to assess the neurovascular relationships at the REZ of the trigeminal and facial nerves. Eleven patients subsequently underwent MVD. Preoperative MR imaging findings were related to surgical observations and results. CISS MR imaging provided excellent contrast between the cranial nerves, small vessels, and cerebrospinal fluid (CSF) in the CPA. CISS was significantly better than FISP for delineating anatomic detail in the CPA (trigeminal and facial nerves, petrosal vein) and abnormal neurovascular relationships responsible for TN and HFS (vascular contact and deformity at the REZ). Preoperative CISS MR imaging demonstrated precisely the neurovascular relationships at the REZ and identified the offending artery in all seven patients with TN undergoing MVD. CISS MR imaging has high resolution and excellent contrast between cranial nerves, small vessels, and CSF, so can precisely and accurately delineate normal and abnormal neurovascular relationships at the REZ in the CPA, and is a valuable preoperative examination for MVD.

  14. Security of Color Image Data Designed by Public-Key Cryptosystem Associated with 2D-DWT

    Mishra, D. C.; Sharma, R. K.; Kumar, Manish; Kumar, Kuldeep

    2014-08-01

    In present times the security of image data is a major issue. So, we have proposed a novel technique for security of color image data by public-key cryptosystem or asymmetric cryptosystem. In this technique, we have developed security of color image data using RSA (Rivest-Shamir-Adleman) cryptosystem with two-dimensional discrete wavelet transform (2D-DWT). Earlier proposed schemes for security of color images designed on the basis of keys, but this approach provides security of color images with the help of keys and correct arrangement of RSA parameters. If the attacker knows about exact keys, but has no information of exact arrangement of RSA parameters, then the original information cannot be recovered from the encrypted data. Computer simulation based on standard example is critically examining the behavior of the proposed technique. Security analysis and a detailed comparison between earlier developed schemes for security of color images and proposed technique are also mentioned for the robustness of the cryptosystem.

  16. General Approach to Identifying Potential Targets for Cancer Imaging by Integrated Bioinformatics Analysis of Publicly Available Genomic Profiles

    2011-03-01

    Full Text Available Molecular imaging has moved to the forefront of drug development and biomedical research. The identification of appropriate imaging targets has become the touchstone for the accurate diagnosis and prognosis of human cancer. Particularly, cell surface- or membrane-bound proteins are attractive imaging targets for their aberrant expression, easily accessible location, and unique biochemical functions in tumor cells. Previously, we published a literature mining of potential targets for our in-house enzyme-mediated cancer imaging and therapy technology. Here we present a simple and integrated bioinformatics analysis approach that assembles a public cancer microarray database with a pathway knowledge base for ascertaining and prioritizing upregulated genes encoding cell surface- or membrane-bound proteins, which could serve imaging targets. As examples, we obtained lists of potential hits for six common and lethal human tumors in the prostate, breast, lung, colon, ovary, and pancreas. As control tests, a number of well-known cancer imaging targets were detected and confirmed by our study. Further, by consulting gene-disease and protein-disease databases, we suggest a number of significantly upregulated genes as promising imaging targets, including cell surface-associated mucin-1, prostate-specific membrane antigen, hepsin, urokinase plasminogen activator receptor, and folate receptors. By integrating pathway analysis, we are able to organize and map “focused” interaction networks derived from significantly dysregulated entity pairs to reflect important cellular functions in disease processes. We provide herein an example of identifying a tumor cell growth and proliferation subnetwork for prostate cancer. This systematic mining approach can be broadly applied to identify imaging or therapeutic targets for other human diseases.

  17. High Resolution 3d Imaging during the Construction of National Radioactive Waste Repository from BÁTAAPÁTI, Hungary

    2012-12-01

    The Hungarian National Radioactive Waste Repository is being built in the neighborhood of the village called Bátaapáti. The program of the new disposal facility for the low- and intermediate-level wastes (L/ILW) is conducted by PURAM (Public Limited Company for Radioactive Waste Management). The Bátaapáti underground research program began in February 2005, with the excavation of the two inclined exploratory tunnels. These tunnels have 30 m distance between their axes, 10% inclination and 1.7 km length, and have reached the 0 m Baltic sea-level in the Mórágy Granite Formation. The safety of nuclear repository mainly is influenced by the ground behaviour and its fracturing hence mapping of the geological features has a great importance. Because of the less stable ground, the cavern walls were shotcreted after every tunnelling advance. The site geologists were required to make the tunnel mapping after every drill and blast cycle. The time interval was short and the documenting work was unrepeatable due to the shotcrete supported walls, so it was very important to use a modern, precise system to create 3D photorealistic models of the rock surfaces on the excavated tunnel walls. We have chosen the photogrammetric method, because it has adequate resolution and quality for the photo combined 3D models. At the beginning, we had used the JointMetriX3D (JMX) system and subsequently ShapeMetriX3D (SMX) in the repository chamber excavation phase. From the acquired 3D images through geological mapping is performed as the system allows directly measuring geometric information on visible discontinuities such as dip and dip direction. Descriptive rock mass parameters such as spacing, area, roughness are instantly available. In this article we would like to continue that research having made by JMX model of a tunnel face of "TSZV" access tunnel and using SMX model of a tunnel face from "DEK" Chamber. Our studies were carried out by field engineering geologists on further

    Full Text Available The This Ph.D. study tries to answer the question "Do history textbooks have an impact on people's ideas about other cultures?", by comparing the contents of a large sample of in- fluential history textbooks and curricula (covering 1945- 1984 with the results of a wide array of public opinion surveys about the Third World and immigrants (covering 1949- 1987. The theoretical part reviews ethnocentrism, cultural relativism and racism as dimensions of cultural images, focuses attention on the phenomenon and mechanism of influence, and assesses the place of the textbook in the complex network of factors acting upon youngsters and adults, inside and outside the school. The methodological part discusses the value of the two sources (relevance, validity and reliability of surveys; availability and use of history textbooks; comparability of both. Univer- ses of both sources are constructed and samples drawn from them. These samples are analysed with mutually attuned question batteries. The double empirical analysis leads to two series of conclusions and trends that are compared with each other. Five parallel trends are found in textbooks and surveys (dominant but decreasing ethnocentrism; decreasing nationalism; absence of racism; poor awareness of other cultures; social-evolutionist thinking. They coincide in time, while, for textbooks to have influence, trends there should precede these in the public. Four other trends only partially coincide, or diverge. In the case of still two other trends, mutual influence could be plausibly postulated. In globo, no firm evidence was found for the thesis that history textbooks autonomously influence the public. It rather is the general climate of opinion that, with years of delay, acts upon the textbook authors. The role of these authors, the immediate influences upon them (editors, curricula planners, academics, inspectors, teachers, parents and pupils, their biographies and their degree of representativeness

    Little is known about how to reduce unnecessary imaging for low back pain. Understanding clinician, patient and general public beliefs about imaging is critical to developing strategies to reduce overuse. To synthesise qualitative research that has explored clinician, patient or general public beliefs about diagnostic imaging for low back pain. We will perform a qualitative evidence synthesis of relevant qualitative research exploring clinician, patient and general public beliefs about diagnostic imaging for low back pain. Exclusions will be studies not using qualitative methods and studies not published in English. Studies will be identified using sensitive search strategies in MEDLINE, EMBASE, CINAHL, AMED and PsycINFO. Two reviewers will independently apply inclusion and exclusion criteria, extract data, and use the Critical Appraisal Skills Programme quality assessment tool to assess the quality of included studies. To synthesise the data we will use a narrative synthesis approach that involves developing a theoretical model, conducting a preliminary synthesis, exploring relations in the data, and providing a structured summary. We will code the data using NVivo. At least two reviewers will independently apply the thematic framework to extracted data. Confidence in synthesis findings will be evaluated using the GRADE Confidence in the Evidence from Reviews of Qualitative Research tool. Ethical approval is not required to conduct this review. We will publish the results in a peer-reviewed journal. CRD42017076047. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

  20. Measuring Co-Presence and Social Presence in Virtual Environments - Psychometric Construction of a German Scale for a Fear of Public Speaking Scenario.

    Poeschl, Sandra; Doering, Nicola

    2015-01-01

    Virtual reality exposure therapy (VRET) applications use high levels of fidelity in order to produce high levels of presence and thereby elicit an emotional response for the user (like fear for phobia treatment). State of research shows mixed results for the correlation between anxiety and presence in virtual reality exposure, with differing results depending on specific anxiety disorders. A positive correlation for anxiety and presence for social anxiety disorder is not proven up to now. One reason might be that plausibility of the simulation, namely including key triggers for social anxiety (for example verbal and non-verbal behavior of virtual agents that reflects potentially negative human evaluation) might not be acknowledged in current presence questionnaires. A German scale for measuring co-presence and social presence for virtual reality (VR) fear of public speaking scenarios was developed based on a translation and adaption of existing co-presence and social presence questionnaires. A sample of N = 151 students rated co-presence and social presence after using a fear of public speaking application. Four correlated factors were derived by item- and principle axis factor analysis (Promax rotation), representing the presenter's reaction to virtual agents, the reactions of the virtual agents as perceived by the presenter, impression of interaction possibilities, and (co-)presence of other people in the virtual environment. The scale developed can be used as a starting point for future research and test construction for VR applications with a social context.

    2018-01-01

    To critically examine surveillance practices of health visitors (HV) in the UK and public health nurses (PHNs) in Canada. The practice and meaning of surveillance shifts and changes depending on the context and intent of relationships between mothers and HVs or PHNs. We present the context and practice of HVs in the UK and PHNs in Canada and provide a comprehensive literature review regarding surveillance of mothers within public health systems. We then present our critique of the meaning and practice of surveillance across different settings. Concepts from Foucault and discourse analysis are used to critically examine and discuss the meaning of surveillance. Surveillance is a complex concept that shifts meaning and is socially and institutionally constructed through relations of power. Healthcare providers need to understand the different meanings and practices associated with surveillance to effectively inform practice. Healthcare providers should be aware of how their positions of expert and privilege within healthcare systems affect relationships with mothers. A more comprehensive understanding of personal, social and institutional aspects of surveillance will provide opportunities to reflect upon and change practices that are supportive of mothers and their families. © 2017 John Wiley & Sons Ltd.

    Full Text Available To design a fast and accurate semi-automated segmentation method for spinal cord 3T MR images and to construct a template of the cervical spinal cord.A semi-automated double threshold-based method (DTbM was proposed enabling both cross-sectional and volumetric measures from 3D T2-weighted turbo spin echo MR scans of the spinal cord at 3T. Eighty-two healthy subjects, 10 patients with amyotrophic lateral sclerosis, 10 with spinal muscular atrophy and 10 with spinal cord injuries were studied. DTbM was compared with active surface method (ASM, threshold-based method (TbM and manual outlining (ground truth. Accuracy of segmentations was scored visually by a radiologist in cervical and thoracic cord regions. Accuracy was also quantified at the cervical and thoracic levels as well as at C2 vertebral level. To construct a cervical template from healthy subjects' images (n=59, a standardization pipeline was designed leading to well-centered straight spinal cord images and accurate probability tissue map.Visual scoring showed better performance for DTbM than for ASM. Mean Dice similarity coefficient (DSC was 95.71% for DTbM and 90.78% for ASM at the cervical level and 94.27% for DTbM and 89.93% for ASM at the thoracic level. Finally, at C2 vertebral level, mean DSC was 97.98% for DTbM compared with 98.02% for TbM and 96.76% for ASM. DTbM showed similar accuracy compared with TbM, but with the advantage of limited manual interaction.A semi-automated segmentation method with limited manual intervention was introduced and validated on 3T images, enabling the construction of a cervical spinal cord template.

Finally, at C2 vertebral level, mean DSC was 97.98% for DTbM compared with 98.02% for TbM and 96.76% for ASM. DTbM showed similar accuracy compared with TbM, but with the advantage of limited manual interaction. A semi-automated segmentation method with limited manual intervention was introduced and validated on 3T images, enabling the construction of a cervical spinal cord template.

    To explore nursing students' perceptions of how their profession is portrayed on medical television programmes. Recruitment and retention in nursing have been linked to the image of the profession in society. Images of nursing in popular media frequently draw on stereotypes that may damage the appeal of nursing for potential students and denigrate the value and status of the profession. A growing body of work analyses how nursing is portrayed in popular media, but less research asks nursing students themselves to reflect on this area. Convergent parallel mixed methods. Data were collected in 2011 from surveys of 484 undergraduate nursing students at a large university in New South Wales, Australia, that included demographic data, their viewing habits of medical television programmes and their opinions of how the shows handled nursing ethics and professionalism and the image of nursing on television and nursing role models. Most students watch medical television programmes. Students who do not speak English at home watched fewer programmes but were more positive about the depictions of professionalism. The qualitative data showed students were concerned that television can have a negative influence on the image of nursing, but they also recognized some educational and recruitment value in television programmes. It is important for nurses, educators and students to be critically engaged with the image of their profession in society. There is value in engaging more closely with contemporary media portrayals of nursing for students and educators alike. © 2013 John Wiley & Sons Ltd.

    Advanced robotic vehicles are increasingly being used by oceanographic research vessels to enable more efficient and widespread exploration of the ocean, particularly the deep ocean. With cutting-edge capabilities mounted onto robotic vehicles, data at high resolutions is being generated more than ever before, enabling enhanced data collection and the potential for broader participation. For example, high resolution camera technology not only improves visualization of the ocean environment, but also expands the capacity to engage participants remotely through increased use of telepresence and virtual reality techniques. Schmidt Ocean Institute is a private, non-profit operating foundation established to advance the understanding of the world's oceans through technological advancement, intelligent observation and analysis, and open sharing of information. Telepresence-enabled research is an important component of Schmidt Ocean Institute's science research cruises, which this presentation will highlight. Schmidt Ocean Institute is one of the only research programs that make their entire underwater vehicle dive series available online, creating a collection of video that enables anyone to follow deep sea research in real time. We encourage students, educators and the general public to take advantage of freely available dive videos. Additionally, other SOI-supported internet platforms, have engaged the public in image and video annotation activities. Examples of these new online platforms, which utilize citizen scientists to annotate scientific image and video data will be provided. This presentation will include an introduction to SOI-supported video and image tagging citizen science projects, real-time robot tracking, live ship-to-shore communications, and an array of outreach activities that enable scientists to interact with the public and explore the ocean in fascinating detail.

    Recognizing the value and unmet need for label-free kinetic cell analysis, Phase Holograhic Imaging defines its market segment as automated, easy to use and affordable time-lapse cytometry. The process of developing new technology, meeting customer expectations, sources of corporate funding and R&D adjustments prompted by field experience will be reviewed. Additionally, it is discussed how relevant biological information can be extracted from a sequence of quantitative phase images, with negligible user assistance and parameter tweaking, to simultaneously provide cell culture characteristics such as cell growth rate, viability, division rate, mitosis duration, phagocytosis rate, migration, motility and cell-cell adherence without requiring any artificial cell manipulation.

  7. New Analysis Method Application in Metallographic Images through the Construction of Mosaics Via Speeded Up Robust Features and Scale Invariant Feature Transform

    Full Text Available In many applications in metallography and analysis, many regions need to be considered and not only the current region. In cases where there are analyses with multiple images, the specialist should also evaluate neighboring areas. For example, in metallurgy, welding technology is derived from conventional testing and metallographic analysis. In welding, these tests allow us to know the features of the metal, especially in the Heat-Affected Zone (HAZ; the region most likely for natural metallurgical problems to occur in welding. The expanse of the Heat-Affected Zone exceeds the size of the area observed through a microscope and typically requires multiple images to be mounted on a larger picture surface to allow for the study of the entire heat affected zone. This image stitching process is performed manually and is subject to all the inherent flaws of the human being due to results of fatigue and distraction. The analyzing of grain growth is also necessary in the examination of multiple regions, although not necessarily neighboring regions, but this analysis would be a useful tool to aid a specialist. In areas such as microscopic metallography, which study metallurgical products with the aid of a microscope, the assembly of mosaics is done manually, which consumes a lot of time and is also subject to failures due to human limitations. The mosaic technique is used in the construct of environment or scenes with corresponding characteristics between themselves. Through several small images, and with corresponding characteristics between themselves, a new model is generated in a larger size. This article proposes the use of Digital Image Processing for the automatization of the construction of these mosaics in metallographic images. The use of this proposed method is meant to significantly reduce the time required to build the mosaic and reduce the possibility of failures in assembling the final image; therefore increasing efficiency in obtaining

    Active shape models bear a great promise for model-based medical image analysis. Their practical use, though, is undermined due to the need to train such models on large image databases. Automatic building of point distribution models (PDMs) has been successfully addressed and a number of autolandmarking techniques are currently available. However, the need for strategies to automatically build intensity models around each landmark has been largely overlooked in the literature. This work demonstrates the potential of creating intensity models automatically by simulating image generation. We show that it is possible to reuse a 3D PDM built from computed tomography (CT) to segment gated single photon emission computed tomography (gSPECT) studies. Training is performed on a realistic virtual population where image acquisition and formation have been modeled using the SIMIND Monte Carlo simulator and ASPIRE image reconstruction software, respectively. The dataset comprised 208 digital phantoms (4D-NCAT) and 20 clinical studies. The evaluation is accomplished by comparing point-to-surface and volume errors against a proper gold standard. Results show that gSPECT studies can be successfully segmented by models trained under this scheme with subvoxel accuracy. The accuracy in estimated LV function parameters, such as end diastolic volume, end systolic volume, and ejection fraction, ranged from 90.0% to 94.5% for the virtual population and from 87.0% to 89.5% for the clinical population.

    Full Text Available Negative refraction properties of a two-dimensional phononic crystal (PC, made of a triangular lattice of steel rods embedded in epoxy are investigated both experimentally and numerically. First, experiments have been carried out on a prism shaped PC immersed in water. Then, for focusing purposes, a flat lens is considered and the construction of the image of a point source is analyzed in details, when indices are matched between the PC and the surrounding fluid medium, whereas acoustic impedances are mismatched. Optimal conditions for focusing longitudinal elastic waves by such PC flat lens are then discussed.

  16. Deictic Reference as a Means for Constructing the Character Image in a Dubbed Cartoon Snow Postman: Comparative Analysis of the Lithuanian, Russian and English Versions

    Directory of Open Access Journals (Sweden)

    Danguolė Satkauskaitė

    2015-06-01

    Full Text Available The article aims at examining how the main character Snowman’s image is constructed by applying an abundant number of deictic expressions in the Lithuanian, Russian and English versions of the cartoon Snow Postman. The research was based on M. Consten’s conception of direct and indirect reference and the model of visual-verbal cohesion proposed by N. Baumgarten. The study has revealed that in both, Russian and Lithuanian versions of the cartoon, the main character’s dialogues are loaded with deictic expressions which mark the same referents. In this way, the main character is shaped as a dull, forgetful being, unable to store and process a huge amount of information in his head. In the English version, deictic instances are sparsely used, thus the character image is quite different here: the snowman is less absent-minded and fuzzy.

    2011-01-01

    The design and construction of a PET camera module with high sensitivity, full 3-D spatial reconstruction and very good energy resolution is presented. The basic principle consists of an axial arrangement of long scintillation crystals around the Field Of View (FOV), providing a measurement of the transverse coordinates of the interacting 511 keV gamma ray. On top of each layer of crystals, an array of Wave-Length Shifter (WLS) strips, which collect the light leaving the crystals sideways, is positioned orthogonal to the crystal direction. The signals in the WLS strips allow a precise measurement of the z (axial) co-ordinate of the 511 keV gamma-ray gamma impact. The construction of two modules used for demonstration of the concept is described. First preliminary results on spatial and energy resolution from one full module will be shown.

    Compared with traditional confocal microscopy, two-photon fluorescence microscopy (TPFM), which excites a two-photon (TP) fluorophore by near-infrared light, provides improved three-dimensional image resolution with increased tissue-image depth (>500 μm) and an extended observation time. Therefore, the development of novel functional TP fluorophores has attracted great attention in recent years. Herein, a novel TP fluorophore CM-NH2, which have the donor-π-acceptor (D-π-A)-structure, was designed and synthesized. We further used this dye developed a new type of TP fluorescent probe CM-NO2 for detecting nitroreductase (NTR). Upon incubated with NTR for 15 min, CM-NO2 displayed a 90-fold fluorescence enhancement at 505 nm and the maximal TP action cross-section value after reaction was detected and calculated to be 200 GM at 760 nm. The probe exhibited excellent properties such as high sensitivity, high selectivity, low cytotoxicity, and high photostability. Moreover, the probe was utilized to image the tumor hypoxia in live HeLa cells. Finally, using the CM-NO2 to image NTR in tissues was demonstrated.

    The initial conditions of the darkroom and X rays films processing of two public hospitals, called A and B hospitals, at Aracaju-SE city had been evaluated. This evaluation was performed to define the actions for an Quality Assurance Program (QAP) aiming to improve the radiographic images quality and costs reduction for both hospitals. The evaluation of the initial conditions of the hospital B showed that a large reduction in the film rejection index and in its radiographic image artifacts can be obtained after the QAP deeds be accomplished. In the A hospital, the actions that have been deployed by the AQP resulted in a reduction of about 50% of the costs associated to chemical products consumption and improved the radiographic image quality. It was demonstrated by a decrease in the radiographs rejection index of 7 % to 5%. The results also revealed that the presence of a medical physicist able to follow the QAP is essential, because, without him, the program, in general, is neglected. (author)

  2. Image charge models for accurate construction of the electrostatic self-energy of 3D layered nanostructure devices

    Barker, John R.; Martinez, Antonio

    2018-04-01

    Efficient analytical image charge models are derived for the full spatial variation of the electrostatic self-energy of electrons in semiconductor nanostructures that arises from dielectric mismatch using semi-classical analysis. The methodology provides a fast, compact and physically transparent computation for advanced device modeling. The underlying semi-classical model for the self-energy has been established and validated during recent years and depends on a slight modification of the macroscopic static dielectric constants for individual homogeneous dielectric regions. The model has been validated for point charges as close as one interatomic spacing to a sharp interface. A brief introduction to image charge methodology is followed by a discussion and demonstration of the traditional failure of the methodology to derive the electrostatic potential at arbitrary distances from a source charge. However, the self-energy involves the local limit of the difference between the electrostatic Green functions for the full dielectric heterostructure and the homogeneous equivalent. It is shown that high convergence may be achieved for the image charge method for this local limit. A simple re-normalisation technique is introduced to reduce the number of image terms to a minimum. A number of progressively complex 3D models are evaluated analytically and compared with high precision numerical computations. Accuracies of 1% are demonstrated. Introducing a simple technique for modeling the transition of the self-energy between disparate dielectric structures we generate an analytical model that describes the self-energy as a function of position within the source, drain and gated channel of a silicon wrap round gate field effect transistor on a scale of a few nanometers cross-section. At such scales the self-energies become large (typically up to ~100 meV) close to the interfaces as well as along the channel. The screening of a gated structure is shown to reduce the self

    To assess the value of 3 dimensional fourier transformation interference in steady state magnetic resonance imaging(3DFT CISS MRI) in depicting the inner ear and vascular structures. Using 3DFT CISS axial and coronal MRI scans of both ears with 17.1msec/8.0msec/50 degree(TR/TE/FA) and 0.9mm in nominal thickness, we studied 68 normal ears of 34 volunteers aged between 15 and 54 years. We assessed the visualization of the membranous labyrinth, and of cranial nerves VII and VIII in the inner ear canal. We analyzed the location of the vascular loop of the anterior inferior cerebellar artery in relation to cranial nerves VII and internal auditory canal. To define the three-dimensional images of the membranous labyrinth, MIP reconstruction of axial images was carried out. The very high signal of the intralabyrinth fluid enabled one hundred percent of the membranous labrynth to be seen There was a lack of contrast between soft tissue and bone such as the facial verve canal, vestibular aqueduct and canal of the subarcuate artery. In 25% of cases, the vascular loop was recognized in the porus acusticus, and in 6% of cases, inside the internal auditory canal. 3DFT CISS MRI is useful for determining the detailed anatomy of the inner ear and the nearby vascular loop. This special MR technique can be added as a routine protocol in the study of diseases of the inner ear

    Cardiac computer models can help us understand and predict the propagation of excitation waves (i.e., action potential, AP) in healthy and pathologic hearts. Our broad aim is to develop accurate 3D MR image-based computer models of electrophysiology in large hearts (translatable to clinical applications) and to validate them experimentally. The specific goals of this paper were to match models with maps of the propagation of optical AP on the epicardial surface using large porcine hearts with scars, estimating several parameters relevant to macroscopic reaction-diffusion electrophysiological models. We used voltage-sensitive dyes to image AP in large porcine hearts with scars (three specimens had chronic myocardial infarct, and three had radiofrequency RF acute scars). We first analyzed the main AP waves' characteristics: duration (APD) and propagation under controlled pacing locations and frequencies as recorded from 2D optical images. We further built 3D MR image-based computer models that have information derived from the optical measures, as well as morphologic MRI data (i.e., myocardial anatomy, fiber directions and scar definition). The scar morphology from MR images was validated against corresponding whole-mount histology. We also compared the measured 3D isochronal maps of depolarization to simulated isochrones (the latter replicating precisely the experimental conditions), performing model customization and 3D volumetric adjustments of the local conductivity. Our results demonstrated that mean APD in the border zone (BZ) of the infarct scars was reduced by ~13% (compared to ~318 ms measured in normal zone, NZ), but APD did not change significantly in the thin BZ of the ablation scars. A generic value for velocity ratio (1:2.7) in healthy myocardial tissue was derived from measured values of transverse and longitudinal conduction velocities relative to fibers direction (22 cm/s and 60 cm/s, respectively). The model customization and 3D volumetric

    2010-12-01

    Despite the salience of health disparities in media and policy discourse, little previous research has investigated if imagery associating an illness with a certain racial group influences public perceptions. This study evaluated the influence of the media's presentation of the causes of type 2 diabetes and its implicit racial associations on attitudes toward people with diabetes and preferences toward research spending. Survey participants who viewed an article on genetic causation or social determinants of diabetes were more likely to support increased government spending on research than those viewing an article with no causal language, while participants viewing an article on behavioral choices were more likely to attribute negative stereotypes to people with diabetes. Participants who viewed a photo of a black woman accompanying the article were less likely to endorse negative stereotypes than those viewing a photo of a white woman, but those who viewed a photo of a glucose-testing device expressed the lowest negative stereotypes. The effect of social determinants language was significantly different for blacks and whites, lowering stereotypes only among blacks. Emphasizing the behavioral causes of diabetes, as is common in media coverage, may perpetuate negative stereotypes. While drawing attention to the social determinants that shape these behaviors could mitigate stereotypes, this strategy is unlikely to influence the public uniformly.

    Hip fractures due to osteoporosis are increasing progressively across the globe. It is also difficult for those fractured patients to undergo dual-energy X-ray absorptiometry scans due to its complicated protocol and its associated cost. The utilisation of computed tomography for the fracture treatment has become common in the clinical practice. It would be helpful for orthopaedic clinicians, if they could get some additional information related to bone strength for better treatment planning. The aim of our study was to develop an automated system to segment the femoral neck region, extract the cortical and trabecular bone parameters, and assess the bone strength using an isotropic volume construction from clinical computed tomography images. The right hip computed tomography and right femur dual-energy X-ray absorptiometry measurements were taken from 50 south-Indian females aged 30-80 years. Each computed tomography image volume was re-constructed to form isotropic volumes. An automated system by incorporating active contour models was used to segment the neck region. A minimum distance boundary method was applied to isolate the cortical and trabecular bone components. The trabecular bone was enhanced and segmented using trabecular enrichment approach. The cortical and trabecular bone features were extracted and statistically compared with dual-energy X-ray absorptiometry measured femur neck bone mineral density. The extracted bone measures demonstrated a significant correlation with neck bone mineral density (r > 0.7, p computed tomography images scanned with low dose could eventually be helpful in osteoporosis diagnosis and its treatment planning. © IMechE 2016.

    Nanotechnology is the design and assembly of submicroscopic devices called nanoparticles, which are 1-100 nm in diameter. Nanomedicine is the application of nanotechnology for the diagnosis and treatment of human disease. Disease-specific receptors on the surface of cells provide useful targets for nanoparticles. Because nanoparticles can be engineered from components that (1) recognize disease at the cellular level, (2) are visible on imaging studies, and (3) deliver therapeutic compounds, nanotechnology is well suited for the diagnosis and treatment of a variety of diseases. Nanotechnology will enable earlier detection and treatment of diseases that are best treated in their initial stages, such as cancer. Advances in nanotechnology will also spur the discovery of new methods for delivery of therapeutic compounds, including genes and proteins, to diseased tissue. A myriad of nanostructured drugs with effective site-targeting can be developed by combining a diverse selection of targeting, diagnostic, and therapeutic components. Incorporating immune target specificity with nanostructures introduces a new type of treatment modality, nano-immunochemotherapy, for patients with cancer. In this review, we will discuss the development and potential applications of nanoscale platforms in medical diagnosis and treatment. To impact the care of patients with neurological diseases, advances in nanotechnology will require accelerated translation to the fields of brain mapping, CNS imaging, and nanoneurosurgery. Advances in nanoplatform, nano-imaging, and nano-drug delivery will drive the future development of nanomedicine, personalized medicine, and targeted therapy. We believe that the formation of a science, technology, medicine law-healthcare policy (STML) hub/center, which encourages collaboration among universities, medical centers, US government, industry, patient advocacy groups, charitable foundations, and philanthropists, could significantly facilitate such

    Full Text Available The practice of yoga in Bogotá has a particular vision of the body that promotes a form of co-implicit, holistic and totalizing existence, inserted into the constant logic of a spiritual experience materialized in the individual body. This vision is directly related to a reciprocal concept of health and disease, which establishes its limits beyond the atomized and institutionalized corporal vision of Western biomedical medicine. Eastern spirituality promotes “new forms” of experiencing health and sickness, which find a commercial resonance with complimentary health service providers that grow more influential within a local context; additionally, they have also found fertile ground in the urban imaginary of Bogotá, appearing on scene with a certain body-psychic-spiritual ideal related to something beyond just well-being; an image promoted by the publishing industry and market logic in the different mass communication media

    2012-01-01

    Due to its late incorporation into the national State, the social, economic and political setting of the Argentine province Tierra del Fuego differed from that of the rest of the national territory. In the construction of dependent otherness, objectifications and representations were imposed by state-related and non-state-related institutions, among other agencies. In this context, the Salesian mission of La Candelaria and Ushuaia's Jail for recidivists stand out as spaces in which biopolitics was concretised. The native population and criminals in Tierra del Fuego were those to be subjugated. The thesis of the extinction of the Indian and the simultaneous exaltation of the criminal as the subject of progress identified the scientific and political mechanisms by which the exclusion of certain social groups (Tierra del Fuego's indigenous population) and the inclusion of others (criminals) were regulated.

    This work presents a new approach in the construction of voxel-based phantoms that was implemented to simplify the segmentation process of organs and tissues reducing the time used in this procedure. The segmentation process is performed by painting tomographic images and attributing a different color for each organ or tissue. A voxel-based head and neck phantom was built using this new approach. The way as the data are stored allows an increasing in the performance of the radiation transport code. The program that calculates the radiation transport also works with image files. This capability allows image reconstruction showing isodose areas, under several points of view, increasing the information to the user. Virtual X-ray photographs can also be obtained allowing that studies could be accomplished looking for the radiographic techniques optimization assessing, at the same time, the doses in organs and tissues. The accuracy of the program here presented, called MCvoxEL, that implements this new approach, was tested by comparison to results from two modern and well-supported Monte Carlo codes. Dose conversion factors for parallel X-ray exposure were also calculated. (author)

    We compared contrast-enhanced T1-weighted and 3D constructive interference in steady state (CISS) sequences for demonstrating possible prognostic factors in hearing-preservation surgery for vestibular schwannoma. We studied 22 patients with vestibular schwannomas having hearing-preservation surgery. Postoperatively six (27%) had a facial palsy and eight (36%) had hearing loss. There was a significant correlation between the size of the tumour and facial palsy (r=-0.72). Both techniques adequately demonstrated all tumours. Involvement of the fundus of the internal auditory canal (IAC) and a small distance between the lateral border of the tumour and the fundus were correlated significantly with hearing loss (r=-0.81 and -0.75, respectively). The 3D-CISS sequence, by virtue of its high contrast resolution was superior to T1-weighted images (P<0.05) for detection of the fundal involvement. The direction of displacement of the facial nerve did not correlate with facial palsy or hearing loss. We think that 3D-CISS images better show the features influencing surgical outcome, but that contrast-enhanced T1-weighted images are required for diagnosis. (orig.)

    Full Text Available Abstract The present work describes setting up a laboratory unit for supercritical fluid extraction. In addition to its construction, a survey of cost was done to compare the cost of the homemade unit with that of commercial units. The equipment was validated using an extraction of annatto seeds’ oil, and the extraction and fractionation of fennel oil were used to validate the two separators; for both systems, the solvent was carbon dioxide. The chemical profiles of annatto and fennel extracts were assessed using thin layer chromatography; the images of the chromatographic plates were processed using the free ImageJ software. The cost survey showed that the homemade equipment has a very low cost (~US$ 16,000 compared to commercial equipment. The extraction curves of annatto were similar to those obtained in the literature (yield of 3.8% oil. The separators were validated, producing both a 2.5% fraction of fennel seed extract rich in essential oils and another extract fraction composed mainly of oleoresins. The ImageJ software proved to be a low-cost tool for obtaining an initial evaluation of the chemical profile of the extracts.

    This protocol describes the production and operation of a microfluidic dissection platform for long-term, high-resolution imaging of budding yeast cells. At the core of this platform is an array of micropads that trap yeast cells in a single focal plane. Newly formed daughter cells are subsequently washed away by a continuous flow of fresh culture medium. In a typical experiment, 50-100 cells can be tracked during their entire replicative lifespan. Apart from aging-related research, the microfluidic platform can also be a valuable tool for other studies requiring the monitoring of single cells over time. Here we provide step-by-step instructions on how to fabricate the silicon wafer mold, how to produce and operate the microfluidic device and how to analyze the obtained data. Production of the microfluidic dissection platform and setting up an aging experiment takes ~7 h.

    We describe the front-end electronics for the Cherenkov Ring Imaging Detector (CRID) of the SLD at the Stanford Linear Accelerator Center. The design philosophy and implementation are discussed with emphasis on the low-noise hybrid amplifiers, signal processing and data acquisition electronics. The system receives signals from a highly efficient single-photo electron detector. These signals are shaped and amplified before being stored in an analog memory and processed by a digitizing system. The data from several ADCs are multiplexed and transmitted via fiber optics to the SLD FASTBUS system. We highlight the technologies used, as well as the space, power dissipation, and environmental constraints imposed on the system. 16 refs., 10 figs

    A new gonad shield intended to be used for pubic survey X-ray images is introduced. This protector is mounted on the light sight and produces a shadow free of central radiation on the patient's body. The shield provides such a shape that in women the area limited by the terminal line and in which 95% of the ovaria are situated, is covered, and that in men the region below the pubic angle is protected. The 2 mm thick lead shield has dimensions of 4.0 to 2.5 cm and is inserted into a plexiglass ruler which lies freely movable on a plexiglass plate under the light sight. This shield was tested on the water phantom and on 125 patients. With this protector it was possible to lower the surface dosages calculated by film dosimeters to 20% in women, and also to reduce the gonade dosages to 9% of the dosages without protection. The position of the new gonad protector at a distance from the body provides several advantages: the shield does not alter its position when the patient moves, the protector does not slip off the abdomen in adipose female patients, the radiation protected region has always the same extent, independent from the abdominal curvature of the female patient, the hygienic problems are eliminated, and the shield can be used for both sexes.

    Ajou University School of Medicine made the serially sectioned anatomical images from the Visible Korean Human (VKH) Project in Korea. The VKH images, which are the high-resolution color photographic images, show the organs and tissues in the human body very clearly at 0.2 mm intervals. In this study, we constructed a high-quality voxel model (VKH-Man) with a total of 30 organs and tissues by manual and automatic segmentation method using the serially sectioned anatomical image data from the Visible Korean Human (VKH) project in Korea. The height and weight of VKH-Man voxel model is 164 cm and 57.6 kg, respectively, and the voxel resolution is 1.875 x 1.875 x 2 mm 3 . However, this voxel phantom can be used to calculate the organ and tissue doses of only one person. Therefore, in this study, we adjusted the voxel phantom to the 'Reference Korean' data to construct the voxel phantom that represents the radiation workers in Korea. The height and weight of the voxel model (HDRK-Man) that is finally developed are 171 cm and 68 kg, respectively, and the voxel resolution is 1.981 x 1.981 x 2.0854 mm 3 . VKH-Man and HDRK-Man voxel model were implemented in a Monte Carlo particle transport simulation code for calculation of the organ and tissue doses in various irradiation geometries. The calculated values were compared with each other to see the effect of the adjustment and also compared with other computational models (KTMAN-2, ICRP-74 and VIP-Man). According to the results, the adjustment of the voxel model was found hardly affect the dose calculations and most of the organ and tissue equivalent doses showed some differences among the models. These results shows that the difference in figure, and organ topology affects the organ doses more than the organ size. The calculated values of the effective dose from VKH-Man and HDRK-Man according to the ICRP-60 and upcoming ICRP recommendation were compared. For the other radiation geometries (AP, LLAT, RLAT) except for PA

    A two-day-old female Toggenburg goat with thoracic ectopia cordis (EC) was diagnosed via radiography and computed tomography. The goat was born with EC, defects of the sternum and a supra-umbilical abdominal wall, but without the presence of Cantrell's syndrome. Necropsy and histopathological findings indicated the affected kid had malformation of the heart with an enlarged left ventricle. The findings showed the heart (9 x 5 x 5 cm) stayed outside the thorax, and was covered by a semitransparent membrane. This report is the first to describe a case of thoracic EC in a goat whose sternum was not developed fully and was not connected to the ribs. It is also the first paper to describe three-dimensional images of this condition constructed from computed tomography scans.

    We report the development and validation of an intravascular rotary catheter for bimodal interrogation of arterial pathologies. This is based on a point-spectroscopy scanning time-resolved fluorescence spectroscopy technique enabling reconstruction of fluorescence lifetime images (FLIm) and providing information on arterial intima composition and intravascular ultrasound (IVUS) providing information on arterial wall morphology. The catheter design allows for independent rotation of the ultrasonic and optical channels within an 8 Fr outer diameter catheter sheath and integrates a low volume flushing channel for blood removal in the optical pathways. In the current configuration, the two channels consist of (a) a standard 3 Fr IVUS catheter with single element transducer (40 MHz) and (b) a side-viewing fiber optic (400 μm core). Experiments conducted in tissue phantoms showed the ability of the catheter to operate in an intraluminal setting and to generate coregistered FLIm and IVUS in one pull-back scan. Current results demonstrate the feasibility of the catheter for simultaneous bimodal interrogation of arterial lumen and for generation of robust fluorescence lifetime data under IVUS guidance. These results facilitate further development of a FLIm-IVUS technique for intravascular diagnosis of atherosclerotic cardiovascular diseases including vulnerable plaques.

    In the project of China's First National Geographic Conditions Census, millions of sample data have been collected all over the country for interpreting land cover based on remote sensing images, the quantity of data files reaches more than 12,000,000 and has grown in the following project of National Geographic Conditions Monitoring. By now, using database such as Oracle for storing the big data is the most effective method. However, applicable method is more significant for sample data's management and application. This paper studies a database construction method which is based on relational database with distributed file system. The vector data and file data are saved in different physical location. The key issues and solution method are discussed. Based on this, it studies the application method of sample data and analyzes some kinds of using cases, which could lay the foundation for sample data's application. Particularly, sample data locating in Shaanxi province are selected for verifying the method. At the same time, it takes 10 first-level classes which defined in the land cover classification system for example, and analyzes the spatial distribution and density characteristics of all kinds of sample data. The results verify that the method of database construction which is based on relational database with distributed file system is very useful and applicative for sample data's searching, analyzing and promoted application. Furthermore, sample data collected in the project of China's First National Geographic Conditions Census could be useful in the earth observation and land cover's quality assessment.

    The evaluation of candidate materials and designs for soft tissue scaffolds would benefit from the ability to monitor the mechanical remodeling of the implant site without the need for periodic animal sacrifice and explant analysis. Toward this end, the ability of non-invasive ultrasound elasticity imaging (UEI) to assess temporal mechanical property changes in three different types of porous, biodegradable polyurethane scaffolds was evaluated in a rat abdominal wall repair model. The polymers utilized were salt-leached scaffolds of poly(carbonate urethane) urea, poly(ester urethane) urea and poly(ether ester urethane) urea at 85% porosity. A total of 60 scaffolds (20 each type) were implanted in a full thickness muscle wall replacement in the abdomens of 30 rats. The constructs were ultrasonically scanned every 2 weeks and harvested at weeks 4, 8 and 12 for compression testing or histological analysis. UEI demonstrated different temporal stiffness trends among the different scaffold types, while the stiffness of the surrounding native tissue remained unchanged. The changes in average normalized strains developed in the constructs from UEI compared well with the changes of mean compliance from compression tests and histology. The average normalized strains and the compliance for the same sample exhibited a strong linear relationship. The ability of UEI to identify herniation and to characterize the distribution of local tissue in-growth with high resolution was also investigated. In summary, the reported data indicate that UEI may allow tissue engineers to sequentially evaluate the progress of tissue construct mechanical behavior in vivo and in some cases may reduce the need for interim time point animal sacrifice.

    Service failure frequently occurs. This affects customer expectations which lead to complaint. However, not all dissatisfied customers actually complain. Without customer feedback, it would be impossible for a company to know whether they needed a change for improvement. Thus, complaint management brings a learning experience to organization in order to provide better service. Therefore, it is important to identify customer dissatisfaction through a systematic complaint handling or management. The study proposes a model of systematic complaint management which applied to academic library as a tool of service recovery. As such, the main purpose of this study is to investigate the critical success factors of complaint management towards service quality, customer satisfaction, customer loyalty and the impact to organizational image at academic library. Three academic libraries have been identified and selected for this project, the Library of Tun Sri Lanang, UKM, UTeM and UNIMAS. Using the justice theory, this study investigates the perception of customers on complaint management in terms of outcomes they receive, procedures used by organization and interpersonal treatment. In this study, there are five factors of complaint management identified, which includes speed of recovery, management system, empowerment, culture and psychology and tangible compensation. A questionnaire was designed and used as the data gathering instrument. A total of 600 respondents participated in this study. Ten hypotheses were used to test the relationships between complaint management, service quality, customer satisfaction, customer loyalty and organizational image. To measure the construct relationships, Structural Equation Model (SEM) approach was used. The results show that management system (b = 0.210; p 0.05) do not influence service quality. The second part of this study uses confirmatory factor analysis (CFA) to analyze and confirm the conceptual model proposed in this research

    2013-06-01

    Full Text Available This paper examines the way authors of three medieval Islamic biographical dictionaries portrayed the lives, behavior and characteristics of three key figures of Greco-Roman medicine, Asclepius, Hippocrates and Galen. Particular attention was given to the vocabulary and phrasing used in the biographies, and associations with other literary genres or figures. An analysis of these biographies demonstrates a significant resemblance between the portrayal of these Greco-Roman physicians and the lives of prophetic figures in Islam, and especially that of the Prophet Muḥammad. In addition, these biographies align with features attributed to pious Muslims. This study demonstrates that Muslim biographers constructed these biographies as part of a general tendency to associate medicine with Islam, and the origins of medical knowledge with prophetic wisdom. This study mantains that the connotations and use of this particular terminology allows for a positive view of the science of medicine in these Islamic compositions in which they were included.Este artículo analiza la manera en que los autores de tres diccionarios biográficos islámicos medievales retrataron la vida y características de las tres figuras más destacadas de la medicina greco-romana: Asclepio, Hipócrates y Galeno.

El análisis de estas biografías revela un considerable parecido entre el retrato de estos tres médicos greco-romanos y la vida de algunos profetas en el Islam, especialmente la del Profeta Muḥammad. Asimismo, estas biografías presentan elementos atribuidos a musulmanes piadosos.

    Imaging-based total bacterial count and type identification of bacteria play crucial roles in clinical diagnostics, public health, biological and medical science, and environmental protection. Herein, we designed and synthesized a series of tetraphenylethenes (TPEs) functionalized with one or two aldehyde, carboxylic acid, and quaternary ammonium groups, which were successfully used as fluorescent materials for rapid and efficient staining of eight kinds of representative bacterial species, including pathogenic bacteria Vibrio cholera, Klebsiella pneumoniae, and Listeria monocytogenes and potential bioterrorism agent Yersinia pestis. By comparing the fluorescence intensity changes of the aggregation-induced-emission (AIE) materials before and after bacteria incubation, the sensing mechanisms (electrostatic versus hydrophobic interactions) were simply discussed. Moreover, the designed AIE materials were successfully used as an efficient artificial tongue for bacteria discrimination, and all of the bacteria tested were identified via linear discriminant analysis. Our current work provided a general method for simultaneous broad-spectrum bacterial imaging and species discrimination, which is helpful for bacteria surveillance in many fields.

  13. The construction and legitimation of workplace bullying in the public sector: insight into power dynamics and organisational failures in health and social care.

    Health-care and public sector institutions are high-risk settings for workplace bullying. Despite growing acknowledgement of the scale and consequence of this pervasive problem, there has been little critical examination of the institutional power dynamics that enable bullying. In the aftermath of large-scale failures in care standards in public sector healthcare institutions, which were characterised by managerial bullying, attention to the nexus between bullying, power and institutional failures is warranted. In this study, employing Foucault's framework of power, we illuminate bullying as a feature of structures of power and knowledge in public sector institutions. Our analysis draws upon the experiences of a large sample (n = 3345) of workers in Australian public sector agencies - the type with which most nurses in the public setting will be familiar. In foregrounding these power dynamics, we provide further insight into how cultures that are antithetical to institutional missions can arise and seek to broaden the debate on the dynamics of care failures within public sector institutions. Understanding the practices of power in public sector institutions, particularly in the context of ongoing reform, has important implications for nursing. © 2014 John Wiley & Sons Ltd.

    Full Text Available Public procurement may be examined from different perspectives. Using the Czech Republic as an example, this study is devoted to examining the impact of decisions made by the contracting authority regarding a public tender on the tender process itself and on the outcomes of the tender. The contracting authority addresses a number of decision-making issues regarding public procurements. For example, it needs to decide between two types of criteria (choosing between a single-criterion evaluation or rather opting for several evaluation criteria. At the same time, the authority is free to choose among different types of award procedures while adhering to certain restrictions imposed by the Act on Public Contracts. Using a sample of 1,027 construction work contracts awarded in the Czech Republic, the study examines, in more detail, the impacts of individual choices made by the contracting authority (namely the type of evaluation criteria chosen and the type of procedure for awarding contracts on the estimated and final price of public contracts. Recommendations on how to streamline the process of public procurement can be drawn from conclusions from the empirical analysis.

  4. KARATE WITH CONSTRUCTIVE LEARNING

    Full Text Available Any conventional learning process involves the traditional hierarchy of garnering of information and then recall gathered information. Constructive learning is an important research area having wide impact on teaching methods in education, learning theories, and plays a major role in many education reform movements. It is observed that constructive learning advocates the interconnection between emotions and learning. Human teachers identify the emotions of students with varying degrees of accuracy and can improve the learning rate of the students by motivating them. In learning with computers, computers also should be given the capability to recognize emotions so as to optimize the learning process. Image Processing is a very popular tool used in the process of establishing the theory of Constructive Learning. In this paper we use the Optical Flow computation in image sequences to analyze the accuracy of the moves of a karate player. We have used the Lucas-Kanade method for computing the optical flow in image sequences. A database consisting of optical flow images by a group of persons learning karate is formed and the learning rates are analyzed in order to main constructive learning. The contours of flow images are compared with the standard images and the error graphs are plotted. Analysis of the emotion of the amateur karate player is made by observing the error plots.

    Red brick and interlocking brick are the building materials that are often used for wall installation work on houses construction. In the development of building materials technology and cost savings, interlocking brick can be alternative to replace red bricks. In Aceh Province, the use of interlocking bricks is less popular compared to other big cities in Indonesia. Interlocking brick is made from a mixture of clay, concrete sand and compacted cement and one of the environmentally friendly materials because it does not burn the process like red brick material. It is named interlocking brick because the installation method is locked together and it serves as a structural and partition wall of residential buildings. The aims of this study are to compare the cost of building a house in Banda Aceh City using red brick and interlock brick building materials. The data were obtained from interviews and questionnaires distributed to respondents who had built houses in Banda Aceh City. The results concluded that the house construction cost using interlock brick offer lower construction cost at comparable quality rather than using red brick.

    Full Text Available Procurement instruments by Public Private Partnerships (PPP have shown their amazing capacity in procuring public works from around the globe. Their success rate has been immense as they are known to bring efficiency, quality, innovation, experience, funds, and most importantly, the art of risk sharing to developed projects. This research aims to pinpoint the critical success factors (CSFs that are needed to implement PPPs in transitional economies. We have taken UAE as a case study and will be comparing its results with that of the UK’s; a developed country. Relevant data was collected through a questionnaire to establish the PPP critical success factors for the each of the two countries. In this questionnaire, data was collected from 30 participants residing in the UAE and 62 participants residing in the UK. A comparative analysis between the results of the UK and UAE showed a great deal of similarity between the two in PPP practice trends in the critical success factors. Both countries ranked the same nine factors as the most significant ones out of the eighteen critical success factors for implementing PPPs. These factors were commitment of public and private parties, appropriate risk allocation, committed and competent public agency, transparent procurement process, strong private consortium, competitive procurement process, political support, detailed cost/benefits assessment, and good governance. Whereas, the major differences were related to local financial market, macro-economic conditions, and favourable legal framework. The findings were validated through a small sample of practitioners using the Partnering Performance Index, and were found to be comprehensive, objective, reliable, practical, replicable, and adaptable.

    This study was undertaken to compare the entrance surface dose (ESD) and image quality of adult chest and abdominal X-ray examinations conducted at general practitioner (GP) clinics, and public and private hospitals in Malaysia. The surveyed facilities were randomly selected within a given category (28 GP clinics, 20 public hospitals and 15 private hospitals). Only departmental X-ray units were involved in the survey. Chest examinations were done at all facilities, while only hospitals performed abdominal examinations. This study used the x-ray attenuation phantoms and protocols developed for the Nationwide Evaluation of X-ray Trends (NEXT) survey program in the United States. The ESD was calculated from measurements of exposure and clinical geometry. An image quality test tool was used to evaluate the low-contrast detectability and high-contrast detail performance under typical clinical conditions. The median ESD value for the adult chest X-ray examination was the highest (0.25 mGy) at GP clinics, followed by private hospitals (0.22 mGy) and public hospitals (0.17 mGy). The median ESD for the adult abdominal X-ray examination at public hospitals (3.35 mGy) was higher than that for private hospitals (2.81 mGy). Results of image quality assessment for the chest X-ray examination show that all facility types have a similar median spatial resolution and low-contrast detectability. For the abdominal X-ray examination, public hospitals have a similar median spatial resolution but larger low-contrast detectability compared with private hospitals. The results of this survey clearly show that there is room for further improvement in performing chest and abdominal X-ray examinations in Malaysia. (authors)

    This paper examines the advantages of the use of excretory urography for diagnosis. According to the authors, excretory urography remains the basic radiologic examination of the urinary tract and is the foundation for the evaluation of suspected urologic disease. Despite development of the newer diagnostic modalities such as isotope scanning, ultrasonography, CT, and magnetic resonsance imaging (MRI), excretory urography has maintained a prominent role in ruorradiology. Some indications have been altered and will continue to change with the newer imaging modalities, but the initial evaluation of suspected urinary tract structural abnormalities; hematuria, pyuria, and calculus disease is best performed with excretory urography. The examination is relatively inexpensive and simple to perform, with few contraindictions. Excretory urography, when properly performed, can provide valuable information about the renal parenchyma, pelvicalyceal system, ureters, and urinary bladder

    2011-01-01

    Current subjective image quality assessments have been developed in the laboratory environments, under controlledconditions, and are dependent on the participation of limited numbers of observers. In this research, with the help of Web 2.0 and social media technology, a new method for building a subjective image quality metric has been developed where the observers are the Internet users. A website with a simple user interface that enables Internet users from anywhere at any time to vote for a better quality version of a pair of the same image has been constructed. Users' votes are recorded and used to rank the images according to their perceived visual qualities. We have developed three rank aggregation algorithms to process the recorded pair comparison data, the first uses a naive approach, the second employs a Condorcet method, and the third uses the Dykstra's extension of Bradley-Terry method. The website has been collecting data for about three months and has accumulated over 10,000 votes at the time of writing this paper. Results show that the Internet and its allied technologies such as crowdsourcing offer a promising new paradigm for image and video quality assessment where hundreds of thousands of Internet users can contribute to building more robust image quality metrics. We have made Internet user generated social image quality (SIQ) data of a public image database available online (http://www.hdri.cs.nott.ac.uk/siq/) to provide the image quality research community with a new source of ground truth data. The website continues to collect votes and will include more public image databases and will also be extended to include videos to collect social video quality (SVQ) data. All data will be public available on the website in due course.

    Full Text Available This paper aims to give description about how to use frame analysis in Public Relations (PR research. The author use two framing models: Entman and Pan & Kosicki. The object is organization official statement about particular issue. Frame analysis method rarely used in Public Relations research. This methods commonly use in journalism study, to analyse the news in media. Meanwhile, the key word of framing is the social construction of reality. Organization can make social construction of realty in their official statement. In acacemic term, frame analysis in PR research is useful to know how organization positioned themselves in particular situation. Other benefit is use to evaluat whether the organization frame is conformable with the public opinion or agenda setting media or not. In practical term, frame analysis give benefit for PR practitioner to create the message that can be undserstood by public, also give positive image for organization.

    Full Text Available The goal of this study is to deal with some ethical causes in the public administration, that aim the avoidance of negative phenomenon’s as theft, corruption, etc. In this direction, the debates about ethics are becoming more and more a global tendency, as an implement through which would be found the way to get out of the crisis. The success in the reforms of the public administrations in major part depends, on the public functionaries and their willingness to make fundamental changes in the way they work. In this direction, the State should strengthen and modernize the public service, should realize an employment system, which should reflect more the merits on its service. For this reason, the government’s attempts should be concentrated on the construction of a positive image for the state and its administration as professional objective, which is oriented to the services. Being aware for the practical restrictions of this study, we firstly chose to concentrate on the local public administrations ethics. The study will be focused on the practical comparative analysis of the city of Shkodra and Durres by the realization of a questionnaire by each of these municipalities and the Agency of Legalization and Urbanization of Informal Zones (ALUIZNI in Shkodra.

    Full Text Available Intellectual stimulation is one of the manifestations of transformational leadership. Intellectual stimulation is the aspect of leadership where the leader encourages teams’ ingenuity, creativity and innovative thinking, urging them to keenly question the status quo in order to make discoveries. The purpose of this study was to explore the Influence of intellectual stimulation and conflict resolution on projects implementation. The objective was to determine the Influence of intellectual stimulation and conflict resolution on projects implementation. The study used Expost facto design. Multifactor leadership Questionnaire, Thomas Kilman Instruments, Interview, and documentary analysis were used as tools for data collection. The probability sampling used was stratified and simple random sampling technique. Data was analyzed both quantitatively and qualitatively. Multiple linear regression analysis was used as tool of analysis to test for significance in the hypothesis. One hypothesis was formulated and subsequently tested in the study in order to establish the influence of conflict resolution thereof, in hypothesis H1,( H0: The strength of the relationship between intellectual stimulation and implementation of CDF construction projects does not depend on conflict resolution., it was concluded that the strength of the relationship between intellectual stimulation and implementation of CDF construction projects depends on conflict resolution(P=0.001˂P=0.05,using multiple linear regression analysis the following results were obtained- F value of 7.788,d.f (2,59 and (P-value 0.00˂P= 0.05 significance level which was statistically significant. It was therefore concluded that there is a regression relationship between intellectual stimulation with conflict resolution and implementation of CDF projects.

    2017-04-01

    Among the many "firsts" of the Juno mission is the open enlistment of the public in the operation of its visible camera, JunoCam. Although the scientific thrust of the Juno mission is largely focused on innovative approaches to understanding the structure and composition of Jupiter's interior, JunoCam was added to the payload largely to function in the role of education and public outreach (E/PO). For the first time, the public was able to engage in the discussion and choice of targets for a major NASA mission. The discussion about which features to image is enabled by a continuously updated map of Jupiter's cloud system while Jupiter is far enough from the sun to be observable by non-professional astronomers. Contributors range from very devoted astrophotographers to telescope and video 'hobbyists'. Juno therefore engages the world-wide amateur-astronomy community as a vast network of co-investigators, whose products stimulate conversation and global public awareness of Jupiter and Juno's investigative role. Contributed images also provide a temporal context to inform the Juno atmospheric investigation team of the state and evolution of the atmosphere. The contributed images are used to create s global map on a bi-weekly basis. These bi-weekly maps provide the focus for ongoing discussion about various planetary features over a long time frame. Approximately two weeks before Juno's closest approach to Jupiter on each orbit ("perijove" or PJ), starting in mid-November of 2016 in preparation for PJ3 on December 11, the atmospheric features that have been under discussion and available to JunoCam on that perijove were nominated for voting, and the public at large voted on where to point JunoCam's "elective" features. In addition, JunoCam provides the first close-up images of Jupiter's polar regions from a non-oblique viewpoint for the first time in over 40 years since the passage of Pioneer 11 over Jupiter's north pole. The Juno mission science team also provides

  4. Earthquakes, public spaces and (the social construction of environmental disasters. The role of public space for risk mitigation and urban redevelopment and the role of environmental disasters for re­ assessing the ‘space of the Public’.

    Directory of Open Access Journals (Sweden)

    Barbara Pizzo

    2014-02-01

    Full Text Available This paper stems from long­lasting research dedicated to urban risk reduction through a planning approach. It focuses on public space, proposing an inversion of the usual perspective: instead of considering public spaces for risk mitigation and urban redevelopment, here the imperatives of environmental safety and urban resilience can be instrumental for exploring the meaning and role of the public space from a different, rather compelling point of view. One starting point is the concept of SUM, Strategic Urban Structure (or Framework, from the Italian “Struttura urbana minima”, which has been introduced in order to set out the contents of urban risk reduction in local administration agendas and particularly into ordinary planning processes. The SUM has been conceived both as an analytical and a normative/planning tool. Public spaces are the backbone of both urban structure and of the SUM. From their features, localization, distribution within thesettlement, and their systemic characters, largely depend the capacity of a town to positively react to a seismic event. Six case­studies of small and medium­size historic towns in the Umbria Region (one of the many Italian Regions with a high level of seismic risk, help to understand the complexities and problems related to seismic prevention within historical centres, and the conflicts between conservation of the heritage and the imperatives of environmental safety. In order to overcome possible criticalities identified in a SUM, it is necessary to provide alternatives to its functioning through redundant elements. The concept of redundancy, which is strictly related to that of uncertainty, is very interesting and promising in this field of research.

    Full Text Available Crisis communication models contain strategies to rehabilitate an organization's image, but do not deal with strategies used to damage the image of another player or competitor. Using qualitative content analysis of 178 items published by Palestinian Information Center (PIC, the Hamas's leading website, the purpose of this manuscript is to examine Hamas's efforts to run offensive PR and to harm Israel's image restoration efforts at the time of the flotilla crisis in May 2010. We discover that Hamas deployed a strategy that consisted of five elements: evidence of existence of the crisis event, damages, victims, performance history and undermining the competitor's response.

    Because of the outdated facilities and equipment, and poor operation efficiency in the largest public hospital in Lesotho named Queen Elizabeth II, Lesotho government urgently sought the solution to replace this public hospital for many years. After completing the repair of this hospital, the management of all facilities, equipment and delivery of all clinical services have been totally carried out by a private institutional operator. An independent institution conducts regular assessment of the new hospital and clinics, and the government will pay the bills based on the assessment results. The contract between the government and the private institutional operator lasts for 18 years. The application of this public-private partnerships (PPP) in health service network and the contracting mechanism have increased accountability for health service quality, where the government strengthened its strategic role, and may benefit other public health institutions in Lesotho. If the project can achieve success, the Lesotho government will consider applying PPPs in the reform of other public health institutions.%由于莱索托最大的Queen Elizabeth II公立医院设施、设备陈旧及运行效率低下,莱索托政府多年来迫切寻求可以替代该公立医院的解决方案。对该院进行了修缮,完成后全权由私立机构经营者进行设施、设备的管理和提供医疗服务,由独立机构对新的医院和门诊定期进行评估,政府根据评估的结果来支付费用,政府与私立机构经营者签订的合同为18年。创建政府与私立机构合作(PPP)的卫生服务网络和承包机制增加了对医疗服务质量的问责制,政府在其中加强了其战略性地位,并且这种模式可以让莱索托其他的公共医疗机构受益。如果这个项目能够成功,莱索托政府会考虑将PPPs模式用于其他公共卫生机构的改造。

    Full Text Available This study deals with the concept of „social representation”, a mental construct performing a cognitive function which, at the same time, is perceived as a form of cultural expression and a means to the re-construction of reality. The basic idea is that the build-up of identity as well as the public image makes appeal to the construction of representations both by direct perception and by conveying information in the communication process.

    Full Text Available The purpose of this study was to examine the relationship between job satisfaction and turnover intent of executive level central office administrators in Texas public school districts. For the intent of this study, executive level central office administrators were defined as staff members who serve in one of the following roles in a school district: assistant, associate, area, or deputy superintendent. The data were collected from a random sample of 234 participants in which survey instruments of job satisfaction and turnover intent were used. Each instrument was created on a five-point Likert scale. Based on the results of the study, it was concluded that a moderate inverse relationship exists between job satisfaction and turnover intent and job satisfaction explained 41.3% of an executive level central office administrator’s intent for turnover. Research related to this employee group is lacking. Therefore, not much is known regarding how it relates to their attitude towards work-related factors. Learning more about job satisfaction and turnover intention of these individuals could have long term implications since it relates to mitigating the shortage of superintendent candidates available to fill the growing number of vacancies as well as recruitment, retention, and increased work productivity of these staff.

    Full Text Available This study is situated in the broader identity-construction literature. Bringing discourse community theory to examine teachers’ postings on Facebook Timelines, we explored how teachers discursively construct socially desirable identities to fit into the Timeline community. Data were gathered from the Status updates and Comments on 29 Timelines belonged to Malaysian English language teachers who were purposively chosen as they often posted and commented on teaching-related issues on their Timelines. The analysis shows that the commonest form of identity construction on the teachers’ Timelines was as an engager which had been carefully constructed to portray positive self-image. This paper concludes that when participating on a public networking site, the teachers were being strategic as not to construct identities which could tarnish their professional image.

    Full Text Available Abstract Purpose and background: despite outstanding breakthroughs in medical sciences, breast cancer is still considered one of the most important disease and the most prevalent women cancer and the second reason of death among them. The present study was conducted aiming to compare public health and marital satisfaction among breast cancer patients with breast evacuation, breast keeping and normal women in Tehran. Material and methods: the method of the present study, due to the lack of interference to alter the research variables, was causal comparative. The statistical population included all women with breast cancer and normal women in the city of Tehran. From these people in each group (breast cancer patients with breast evacuation, breast keeping and normal people 80 individuals were selected through available sampling from clients of medical centers and special hospitals in Tehran during October 2012 to December 2013. The applied instruments were the questionnaires of public health, body image, and marital satisfaction. The achieved data were analyzed via one-way ANOVA and Tukey test by SPSS software. Findings: the results of the analysis showed that there is a significant difference between the mean scores of marital satisfaction, body image and public health in three groups (women with cancer who evacuated their breast, those who didn't and normal ones(p<0.01. Conclusion: according to the findings of the present study the women with breast cancer are in more different state in variables of marital satisfaction, mental health and body image comparing to normal group. So it seems necessary for cancer treatment centers to consider psychological treatment courses for these people.

    Human anatomical models have been indispensable to radiation protection dosimetry using Monte Carlo calculations. Existing MIRD-based mathematical models are easy to compute and standardize, but they are simplified and crude compared to human anatomy. This article describes the development of an image-based whole-body model, called VIP-Man, using transversal color photographic images obtained from the National Library of Medicine's Visible Human Project for Monte Carlo organ dose calculations involving photons, electron, neutrons, and protons. As the first of a series of papers on dose calculations based on VIP-Man, this article provides detailed information about how to construct an image-based model, as well as how to adopt it into well-tested Monte Carlo codes, EGS4, MCNP4B, and MCNPX

    Many species of Tephritidae are damaging to fruit, which might negatively impact international fruit trade. Automatic or semi-automatic identification of fruit flies are greatly needed for diagnosing causes of damage and quarantine protocols for economically relevant insects. A fruit fly image identification system named AFIS1.0 has been developed using 74 species belonging to six genera, which include the majority of pests in the Tephritidae. The system combines automated image identification and manual verification, balancing operability and accuracy. AFIS1.0 integrates image analysis and expert system into a content-based image retrieval framework. In the the automatic identification module, AFIS1.0 gives candidate identification results. Afterwards users can do manual selection based on comparing unidentified images with a subset of images corresponding to the automatic identification result. The system uses Gabor surface features in automated identification and yielded an overall classification success rate of 87% to the species level by Independent Multi-part Image Automatic Identification Test. The system is useful for users with or without specific expertise on Tephritidae in the task of rapid and effective identification of fruit flies. It makes the application of computer vision technology to fruit fly recognition much closer to production level. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    A close-to-ideal blend of suburb and city, speedy construction of towers of Babylon, the sparkling proportion of glass and steel buildings’ facade at night showcase the wisdom of humans. They also witness the footsteps, sweats and tears of architects and engineers. Unfortunately, these signatures of human civilizations are swathed in towering figures of construction accidents. Fretting about these on sites, different countries adopt different measures on sites. This book firstly sketches the construction accidents on sites, followed by a review on safety measures in some of the developing countries such as Bermuda, Egypt, Kuwait and China; as well as developed countries, for example, the United States, France and Singapore. It also highlights the enormous compensation costs with the courts’ experiences in the United Kingdom and Hong Kong.

    The present work expresses some ideas on certain characteristics of the public opinion in Argentina with regard to the perception that one has of the use of the nuclear energy and the care of the environment. The work tried to explain the reasons that although Argentina has a long tradition and a considerable international prestige in the generation, investigation and controls of the nuclear energy, at the same time, the argentinean public opinion has not shown in favor of the development of the same one, perceiving that the use of this energy would bring problems for the environment. In the work it was to explain some of the reasons of this opinion state that takes it as a psychological state of people, and that would have elements, symbols and negative interior images in people that work as strongly ingrained beliefs so that the fellows ponder to the nuclear option as the one that less it is wanted for the development of the country. The idea was also developed that these images and negative symbols toward the development of the nuclear energy could have origin in information of the massive media of communication, among other sources that could be persuading to the public opinion through the repetition and to study in depth of these messages toward psychological states contrary to the development of the nuclear energy. The present work tried to explore and to describe this internal universe of the argentinean public opinion with the objective of outlining mechanisms, strategies or action plans from the institutions linked to the nuclear energy that try to open the internal space of people toward an approach more positive with the perception of the development of the nuclear energy in its links with the environment. On this objective, the present work outlined the idea that the opening of the perceptive mark in people would have that to generate it 'not in opposition to the existent beliefs' but trying to win alternative mental spaces in the people.

    2006-06-01

    Full Text Available The use of airborne scanners involves geo-referencing problems, which are difficult because of the need to know the exact platform position and attitude for each scan line. The errors of the onboard navigation system are normally corrected using ground control point on the image. This post-processing correction procedure is too long in case of multiple flight campaigns, and besides it implies the need to have available 1:10000 orthophotoimages or maps in digital format. To optimize the above procedure a new method to correct MIVIS navigational data in the post-processing phase has been implemented. The procedure takes into consideration the GPS stream in Rinex format of common knowledge and findable on the web, acquired at the ground stations of the Geodetic Data Archiving Facilities provided by ASI. The application of this correction entails the assumption that the environmental variables affecting both onboard and geodetic GPS equally affect the position measurements. The airborne data correction was carried out merging the two data sets (onboard and ground station GPS to achieve a more precise aircraft trajectory. The present study compares the geo-coded images obtained by means of the two post-processing methods.

  11. Reconstructing 3D Face Model with Associated Expression Deformation from a Single Face Image via Constructing a Low-Dimensional Expression Deformation Manifold.

    Wang, Shu-Fan; Lai, Shang-Hong

    2011-10-01

    Facial expression modeling is central to facial expression recognition and expression synthesis for facial animation. In this work, we propose a manifold-based 3D face reconstruction approach to estimating the 3D face model and the associated expression deformation from a single face image. With the proposed robust weighted feature map (RWF), we can obtain the dense correspondences between 3D face models and build a nonlinear 3D expression manifold from a large set of 3D facial expression models. Then a Gaussian mixture model in this manifold is learned to represent the distribution of expression deformation. By combining the merits of morphable neutral face model and the low-dimensional expression manifold, a novel algorithm is developed to reconstruct the 3D face geometry as well as the facial deformation from a single face image in an energy minimization framework. Experimental results on simulated and real images are shown to validate the effectiveness and accuracy of the proposed algorithm.

    Full Text Available La identidad o esencia de las enfermeras no coincide con su imagen social pues continua plagada de estereotipos, y el público sigue percibiendo una imagen dependiente y poco profesional de las enfermeras. Esa discordancia entre identidad e imagen, en parte se debe a que las propias enfermeras no se han preocupado suficientemente, de modo individual y colectivo, por comunicar eficazmente su verdadera identidad a la sociedad. Y para transmitir la identidad de las enfermeras estas deben comunicar a la sociedad su función y quehacer, para lo cual conviene que las instituciones enfermeras cuenten con gabinetes de comunicación eficientes y bien estructurados, y que las enfermeras integren en su práctica profesional el uso de recursos de la comunicación pública, tales como aplicar las nuevas tecnologías en su práctica diaria, difundir científica y masivamente su producción intelectual, divulgarla e informar a los medios de actividades enfermeras susceptibles de convertirse en producto informativo.The identity or essence of nursing does not match their social image as this profession continues to be full of stereotypes and the general public still retains the idea of dependence and lack of professionalism of nurses. This lack of concordance between image and identity is partly due to the fact that nurses themselves have not cared enough, both individually and as a group, to communicate effectively their true identity to society. In order to transmit the identity of nursing, these professionals must explain their tasks and functions to society. In this sense, nursing institutions should have at their disposal efficient and well organized communication departments. Also, nurses should include in their daily practice the use of public communication resources such as the application of ITCs to their tasks, the mass divulgation of their intellectual production in scientific publications, the broadcasting of nursing activities which could become

    Tomographic breast imaging techniques can potentially improve detection and diagnosis of cancer in women with radiodense and/or fibrocystic breasts. We have developed a high-resolution positron emission mammography/tomography imaging and biopsy device (called PEM/PET) to detect and guide the biopsy of suspicious breast lesions. PET images are acquired to detect suspicious focal uptake of the radiotracer and guide biopsy of the area. Limited-angle PEM images could then be used to verify the biopsy needle position prior to tissue sampling. The PEM/PET scanner consists of two sets of rotating planar detector heads. Each detector consists of a 4 × 3 array of Hamamatsu H8500 flat panel position sensitive photomultipliers (PSPMTs) coupled to a 96 × 72 array of 2 × 2 × 15 mm3 LYSO detector elements (pitch = 2.1 mm). Image reconstruction is performed with a three-dimensional, ordered set expectation maximization (OSEM) algorithm parallelized to run on a multi-processor computer system. The reconstructed field of view (FOV) is 15 × 15 × 15 cm3. Initial phantom-based testing of the device is focusing upon its PET imaging capabilities. Specifically, spatial resolution and detection sensitivity were assessed. The results from these measurements yielded a spatial resolution at the center of the FOV of 2.01 ± 0.09 mm (radial), 2.04 ± 0.08 mm (tangential) and 1.84 ± 0.07 mm (axial). At a radius of 7 cm from the center of the scanner, the results were 2.11 ± 0.08 mm (radial), 2.16 ± 0.07 mm (tangential) and 1.87 ± 0.08 mm (axial). Maximum system detection sensitivity of the scanner is 488.9 kcps µCi-1 ml-1 (6.88%). These promising findings indicate that PEM/PET may be an effective system for the detection and diagnosis of breast cancer.

Each detector consists of a 4 x 3 array of Hamamatsu H8500 flat panel position sensitive photomultipliers (PSPMTs) coupled to a 96 x 72 array of 2 x 2 x 15 mm{sup 3} LYSO detector elements (pitch = 2.1 mm). Image reconstruction is performed with a three-dimensional, ordered set expectation maximization (OSEM) algorithm parallelized to run on a multi-processor computer system. The reconstructed field of view (FOV) is 15 x 15 x 15 cm{sup 3}. Initial phantom-based testing of the device is focusing upon its PET imaging capabilities. Specifically, spatial resolution and detection sensitivity were assessed. The results from these measurements yielded a spatial resolution at the center of the FOV of 2.01 {+-} 0.09 mm (radial), 2.04 {+-} 0.08 mm (tangential) and 1.84 {+-} 0.07 mm (axial). At a radius of 7 cm from the center of the scanner, the results were 2.11 {+-} 0.08 mm (radial), 2.16 {+-} 0.07 mm (tangential) and 1.87 {+-} 0.08 mm (axial). Maximum system detection sensitivity of the scanner is 488.9 kcps {mu}Ci{sup -1} ml{sup -1} (6.88%). These promising findings indicate that PEM/PET may be an effective system for the detection and diagnosis of breast cancer.

    There is a lack of research examining whether smoking cues in anti-tobacco advertisements elicit cravings, or whether this effect is moderated by countervailing message attributes, such as disgusting images. Furthermore, no research has examined how these types of messages influence nicotine withdrawn smokers' cognitive processing and associated behavioral intentions. At a laboratory session, participants (N = 50 nicotine-deprived adults) were tested for cognitive processing and recognition memory of 12 anti-tobacco advertisements varying in depictions of smoking cues and disgust content. Self-report smoking urges and intentions to quit smoking were measured after each message. The results from this experiment indicated that smoking cue messages activated appetitive/approach motivation resulting in enhanced attention and memory, but increased craving and reduced quit intentions. Disgust messages also enhanced attention and memory, but activated aversive/avoid motivation resulting in reduced craving and increased quit intentions. The combination of smoking cues and disgust content resulted in moderate amounts of craving and quit intentions, but also led to heart rate acceleration (indicating defensive processing) and poorer recognition of message content. These data suggest that in order to counter nicotine-deprived smokers' craving and prolong abstinence, anti-tobacco messages should omit smoking cues but include disgust. Theoretical implications are also discussed.

    Overall quality in radiological protection and medical image depend largely on keeping certain safety standards and technical procedures in good levels. In this way, in June 1998, the Ministry of Health published the document 453 - Guidelines of Radiological Protection to Medical and Dental Practices, defining different levels of actions and responsibility for radiological installation where the critical starting point was the necessity of a previous quality assurance program (QAP) into the radiological service. Preliminary results of a QAP realized in the Department of Radiology of a high complexity Hospital in Rio de Janeiro has showed that, although the importance of 453 Regulation be recognized, there is a few motivation for implementing it. Besides, during 1999 it was possible to identify film losses of 14,9 % related only to the repetition of exposures in the patients, reflecting in terms of cost about U$ 100,000 a year. Results suggest that losses of 64% of total film are due to under or over exposures and 15% are due to inadequate positioning of either film or patient, evidencing the need for training the technical and medical staff .

    Full Text Available The PISA tests applied by OECD in 2012 had a strong impact in Colombia because of the low scores obtained by students . The news had more coverage in the press. In order to establish how they can shape public opinion on the subject because of the manner and direction in which they were addressed, were analyzed news , editorials, opinion columns and letters from readers (total 39 information units appeared in two Colombian daily newspapers in two and a half months. Recognizing the evaluation as a social fact , the analysis focused around : quality of information sources used , breadth of perspective on the evidence by reference to the evidence and formulate action alternatives . The basic conclusions are : the sources of information to give opinion are very limited, they aren´t criticized and the focus is on the scores ; these show a very negative picture that is extended to all the country's education ; teachers are largely responsible for the failure. The opinion that the media contribute to form is negative.

    The performance of functional polymer nanomaterials is a vigorously discussed topic in polymer science. We devoted ourselves to investigating polymer nanomaterials based on near-infrared (NIR) fluorescence imaging and polymer prodrug in this study. Aza-boron dipyrromethene (BODIPY) is an important organic dye, having characteristics such as environmental resistance, light resistance, high molar extinction coefficient, and fluorescence quantum yield. We incorporated it into our target monomer, which can be polymerized without changing its parent structure in a polar solvent and copolymerized with water-soluble monomer to improve the solubility of the dye in an aqueous solution. At the same time, the hydrophobic drug camptothecin (CPT) was designed as a prodrug monomer, and the polymeric nanoparticles (NPs) with NIR fluorescence imaging and prodrug were synthesized in situ in reversible addition-fragmentation chain transfer (RAFT)-mediated aqueous dispersion polymerization. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) revealed the final uniform size of the dual-functional polymeric NPs morphology. The dual-functional polymeric NPs had a strong absorption and emission signal in the NIR region (>650 nm) based on the fluorescence tests. In consideration of the long-term biological toxicity, confocal laser scanning microscopy (CLSM) results indicated that the dual-functional NPs with controlled drug content exhibited effective capability of killing HeLa cells. In addition, in vivo imaging of the dual-functional NPs was observed in real time, and the fluorescent signals clearly demonstrated the dynamic process of prodrug transfer.

    The definition of body image has evolved within research; however, less is known about the layperson's understanding of the construct. This study explored how members and student trainees of an exercise facility (designed for older adults, people with physical disability, and those with cardiac complications) defined body image. Nineteen participants completed a one-on-one interview, and seven of those participants took part in six additional focus group meetings. The following main themes were found: stereotypical assumptions about body image (e.g., it is solely a person's weight or merely a woman's issue), body image continua for positive and negative body image, degree of complexity of body image dimensions, broad considerations of body image (e.g., it is self-esteem), and limited knowledge about body image. These findings suggest a need for knowledge translation between researchers and the general public which informs future body image program design. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2009-07-01

    Full Text Available Catalonia, in common with other nations, has long been concerned with the question of identity and difference. Its problematic relationship with Spain has led to an emphasis on differentiating itself from its larger neighbour (if we are to accept, as most Spaniards do not, that Catalonia is not Spain, a situation complicated by the loss of the Spanish colonies of Cuba and The Philippines in 1898, and the Spanish Civil War and subsequent dictatorship from 1936 to 1976. Beginning in the late nineteenth century, the construction of a Catalan identity followed a similar route to that taken by other European nations such as England, Ireland and, indeed, Spain, including an emphasis on rural values, activities and the countryside, and the conversion of specifically local traditions into national past times. It is only in the last ten years or so that this model of Catalan identity has been recognised for what it is – a model constructed and encouraged for and by specific nationalist political interests. Ironically, Catalonia’s identity abroad has also been constructed and manipulated for political purposes, but from quite a different perspective. Orwell’s /Homage to Catalonia/ (1938 narrates an extremely blinkered version of the Spanish Civil War which has achieved iconic status as a result of cold war politics. Subsequent portrayals of the Spanish Civil War – Valentine Cunningham’s /The Penguin Book of Spanish Civil War Verse/ (ed., Penguin, 1980, or Ken Loach’s 1995 film /Land and Freedom/ base their arguments unquestioningly on /Homage to Catalonia/, perpetuating a view of the nation’s recent history that is both reductive and inaccurate

    2009-12-01

    Full Text Available Sustainable construction is a way for the building and infrastructure industry to move towards achieving sustainable development, taking into account environmental, socioeconomic and cultural issues. Differing approaches and differing economic markets lead to different priorities. This paper presents the construction scenario of Malaysia and the developments in sustainable construction taking place in this country. Barriers to the implementation of sustainable construction are discussed. A list of recommendation was proposed to drive sustainable construction in this country. In conclusion, the status of sustainable construction in Malaysia is still in its infancy. The lack of awareness, training and education, ineffective procurement systems, existing public policies and regulatory frameworks are among the major barriers for sustainable construction in Malaysia. Besides the needs for capacities, technologies and tools, total and ardent commitment by all players in the construction sectors including the governments and the public atlarge are required in order to achieve sustainable construction in Malaysia.

    2016-06-15

    Purpose: Ultrasound (US) is a noninvasive, nonradiographic imaging technique with high spatial and temporal resolution that can be used for localizing soft-tissue structures and tumors in real-time during radiotherapy (inter- and intra-fraction). A detailed methodology integrating 3D-US within RT is presented. This method is easier to adopt into current treatment protocol than current US based systems and reduces user variability for image acquisition, thus eliminating transducer induced changes that limit CT planning system. Methods: We designed an in-house integrated US manipulator and platform to relate CT, 3D-US and linear accelerator coordinate systems. To validate the platform, an agar-based phantom with measured densities and speed-of-sound consistent with tissues surrounding the bladder, was rotated (0–45°) resulting in translations (up to 55mm) relative to the CT and US coordinate systems. After acquiring and integrating CT and US images into the treatment planning system, US-to-US and US-to-CT images were co-registered to re-align the phantom relative to the linear accelerator. Errors in the transformation matrix components were calculate to determine precision of this method under different patient positions. Results: Statistical errors from US-US registrations for different patient orientations ranged from 0.06–1.66mm for x, y, and z translational components, and 0.00–1.05° for rotational components. Statistical errors from US-CT registrations were 0.23–1.18mm for the x, y and z translational components, and 0.08–2.52° for the rotational components. Conclusion: Based on our result, this is consistent with currently used techniques for positioning prostate patients if couch re-positioning is less than a 5 degree rotation. We are now testing this on a dog patient to obtain both inter and intra-fractional positional errors. Additional design considerations include the future use of ultrasound-based functionality (photoacoustics, radioacoustics

    Recent advances in cell therapy and tissue engineering opened new windows for regenerative medicine, but still necessitate innovative noninvasive imaging technologies. We demonstrate that high-resolution magnetic resonance imaging (MRI) allows combining cellular-scale resolution with the ability to detect two cell types simultaneously at any tissue depth. Two contrast agents, based on iron oxide and gadolinium oxide rigid nanoplatforms, were used to "tattoo" endothelial cells and stem cells, respectively, with no impact on cell functions, including their capacity for differentiation. The labeled cells' contrast properties were optimized for simultaneous MRI detection: endothelial cells and stem cells seeded together in a polysaccharide-based scaffold material for tissue engineering appeared respectively in black and white and could be tracked, at the cellular level, both in vitro and in vivo. In addition, endothelial cells labeled with iron oxide nanoparticles could be remotely manipulated by applying a magnetic field, allowing the creation of vessel substitutes with in-depth detection of individual cellular components.

All these are clearly more critical in developing countries. A non-exhaustive set of potential drivers and common barriers to construction industry development is identified from previous research. These suggest the usefulness of consolidating a cluster of recent proposals and exercises aiming at (a construction organization development in terms of an over-arching management support system model, as well as improved information and knowledge management; and (b project team development in the context of relationally integrated teams and supply chains, joint risk management and ‘technology and knowledge exchange’ in joint ventures, as well as longer term public private partnerships. These apparently disparate research thrusts are threaded together into a pattern that may inspire, if not feed, specific research and development (R & D agendas for construction industry development in different countries according to their own priorities, constraints and stages of infrastructure and national development.

  5. Sustainable Construction Risk Perceptions in the Kuwaiti Construction Industry

    2018-06-01

    Full Text Available Sustainable construction is fundamentally different than traditional construction because it requires whole systems thinking, early collaboration across stakeholders, and core principles like reducing resource consumption, eliminating toxins, and applying life cycle costing. Construction professionals unfamiliar with this mindset and approach may perceive sustainable construction as risky. One of the global regions in need of more sustainable construction is the Middle Eastern and North African (MENA region. The MENA region is one of the fastest developing in the world. However, it is the slowest one in implementing sustainable construction practices. Kuwait, in particular, contributes 53% more carbon emissions per capita than the United States. To understand how the Kuwaiti construction industry perceives risks associated with more sustainable construction, a survey was developed with 52 risk elements in which 131 industry professionals responded. The results indicate that industry professionals perceive a lack of public awareness as the risk element with the highest probability of occurrence. The risk element with the highest possible negative impact on future projects is designers’ and contractors’ inexperience with sustainable construction. Other risks were found to include a high initial cost for materials and overall project costs. Educational interventions, changes in risk allocation, and behavioral science to reframe upfront costs as long-term savings are offered as possible solutions.

    The advancement of technology in recent years has provided the production of increasingly sophisticated devices, aiming to acquire medical images with high technical level and also facilitate the operational readiness of the equipment. In order to ensure the most accurate diagnosis with minimum dose without exposing patients to obtain data and verify the performance of a radiographic system for quality control purposes we use the so-called phantoms. Phantoms are physical or computational models used to simulate the transport of ionizing radiation, their interactions in the tissues of the human body and evaluate the deposition of energy. Besides, they are made from materials with behavior similar to human tissues when exposed to ionizing radiation - the so-called tissue-equivalent materials. This paper describes the construction of a physical phantom that allows the execution of the main acceptance tests of the quality control protocols in digital radiography.

    Our goal was to build a probabilistic atlas and anatomical template of the human cervical and thoracic spinal cord (SC) that could be used for segmentation algorithm improvement, parametric group studies, and enrichment of biomechanical modelling. High-resolution axial T2*-weighted images were acquired at 3T on 15 healthy volunteers using a multi-echo-gradient-echo sequence (1 slice per vertebral level from C1 to L2). After manual segmentation, linear and affine co-registrations were performed providing either inter-individual morphometric variability maps, or substructure probabilistic maps [CSF, white and grey matter (WM/GM)] and anatomical SC template. The larger inter-individual morphometric variations were observed at the thoraco-lumbar levels and in the posterior GM. Mean SC diameters were in agreement with the literature and higher than post-mortem measurements. A representative SC MR template was generated and values up to 90 and 100% were observed on GM and WM-probability maps. This work provides a probabilistic SC atlas and a template that could offer great potentialities for parametrical MRI analysis (DTI/MTR/fMRI) and group studies, similar to what has already been performed using a brain atlas. It also offers great perspective for biomechanical models usually based on post-mortem or generic data. Further work will consider integration into an automated SC segmentation pipeline.

    America’s first planetaria all opened in the 1930s, and each was the distinctive product of local circumstances. In Los Angeles, the populist sensibilities of Griffith J. Griffith prompted him to value the transformative power of a personal encounter with a telescope, and he quickly embraced the idea of a public observatory with free access to all. Griffith Observatory and its planetarium emerged from that intent. Authenticity, intelligibility, and theatricality were fundamental principles in Griffith’s thinking, and they were transformed into solid and enduring scientific and astronomical values by those who actually guided the Observatory’s design, construction, and programming. That said, the public profile of Griffith Observatory was most defined by its inspired hilltop location, its distinctive, commanding architecture, and its felicitous proximity to Hollywood. The Observatory is theatric in placement and in appearance, and before the Observatory even opened, it was used as a motion picture set. That continuing vocation turned Griffith Observatory into a Hollywood star. Because entertainment industry objectives and resources were part of the Los Angeles landscape, they influenced Observatory programming throughout the Observatory’s history. Public astronomy in Los Angeles has largely been framed by the Observatory’s fundamental nature. It has exhibits, but it is not a museum. It has a planetarium, but it is essentially an observatory. As a public observatory, it is filled with instruments that transform visitors into observers. This role emphasized the importance of personal experience and established the perception of Griffith Observatory as a place for public gathering and shared contact with the cosmos. The Observatory’s close and continuous link with amateur astronomers made amateurs influential partners in the public enterprise. In full accord with Griffith J. Griffith’s original intent, Griffith Observatory has all been about putting

  11. Surveying for migration pathways in the granitic rock using nuclear track detectors, autoradiography and digital image analysis as an aid to construct the basis for heterogeneous diffusion modeling

    Radioelement migration within a rock matrix under natural long-term conditions is a complex process controlled by various parameters. Pure physical parameters such as porosity, hydraulic conductivity and diffusivity are usually sufficient to describe transport in well-defined laboratory systems. In natural rock matrices transport is influenced by physical pore properties such as pore size distribution, connectivity, tortuosity, constrictivity and petrological and chemical nature and charge on the fluid-rock interface. The overall characterization of heterogeneous rock structures is needed for the accurate heterogeneous diffusion modeling. Here we describe a method for the detection of α-particles from uranium in cm-scale rock samples based on the analysis of the tracks formed in organic polymer, CR-39. On the other hand the uranium tracks were compared with the migration pathways and porosity distribution produced with the 14 C-polymethylmethacrylate impregnation method ( 14 C-PMMA). For analyzing mineral specific uranium occurrence and porosities the staining methods were used to produce the mineral map of the rock sample. Digital image analysis techniques were applied to the different cm-scale pictures of rock samples. Scanning electron microscopy and energy dispersive X-ray analysis (SEM/EDS) were performed in order both to study the pore apertures of grain boundaries and fissures in greater detail and to detect the uranium phases. The high uranium content was found to be congruent with the porous mineral phases; altered plagioclase and biotite grains, and the intra- and intergranular fissures detected with the 14 C-PMMA technique. Plenty of microfractures transsecting potassium feldspar and quartz grains were filled with calcite together with precipitated uranium. Copyright (2001) Material Research Society

  12. Lattice Boltzmann methods applied to large-scale three-dimensional virtual cores constructed from digital optical borehole images of the karst carbonate Biscayne aquifer in southeastern Florida

    Digital optical borehole images at approximately 2 mm vertical resolution and borehole caliper data were used to create three-dimensional renderings of the distribution of (1) matrix porosity and (2) vuggy megaporosity for the karst carbonate Biscayne aquifer in southeastern Florida. The renderings based on the borehole data were used as input into Lattice Boltzmann methods to obtain intrinsic permeability estimates for this extremely transmissive aquifer, where traditional aquifer test methods may fail due to very small drawdowns and non-Darcian flow that can reduce apparent hydraulic conductivity. Variogram analysis of the borehole data suggests a nearly isotropic rock structure at lag lengths up to the nominal borehole diameter. A strong correlation between the diameter of the borehole and the presence of vuggy megaporosity in the data set led to a bias in the variogram where the computed horizontal spatial autocorrelation is strong at lag distances greater than the nominal borehole size. Lattice Boltzmann simulation of flow across a 0.4 × 0.4 × 17 m (2.72 m3 volume) parallel-walled column of rendered matrix and vuggy megaporosity indicates a high hydraulic conductivity of 53 m s-1. This value is similar to previous Lattice Boltzmann calculations of hydraulic conductivity in smaller limestone samples of the Biscayne aquifer. The development of simulation methods that reproduce dual-porosity systems with higher resolution and fidelity and that consider flow through horizontally longer renderings could provide improved estimates of the hydraulic conductivity and help to address questions about the importance of scale.

  13. Construction of Gender Identity in Political Discourse

    Directory of Open Access Journals (Sweden)

    Elizaveta D. Butsyk

    2015-01-01

    Full Text Available The article regards the phenomenon of political communication from the perspective of the particularities of constructing gender identity by politicians. As far as the influence of the gender factor on politicians' speech is concerned, the most relevant approach among many others is the discourse approach formed within the paradigm of cognitive linguistics, which considers political discourse as the object of study. The paper deals with the notion of political discourse and examines a hypothesis that gender factor might have a number of manifestations in political communication. It is noted that studying the specificity of constructing gender identity by politicians in discursive practices is becoming a highly topical issue as the importance of female participation in public and political life is growing. Political decision-making has long been considered the prerogativeofmen, but now the necessity of studying the female factor in this sphere is obvious. The author dwells upon the historical background of linguistic gender studies and summarizes the main stages of their development focusing mainly on the theory of the social construction of gender. The founders of this theory advance the thesis that an individual's gender identity is shaped in the process of constructing gender relations in communicative interaction. Further in the article we analyse a few devices of creating the images of masculinity and femininity by famous English and American politicians. As structural components of gender identity, masculinity and femininity turn out to be modifiable parameters depending on the pragmatic attitudes of communicators. Traditional androcentrism of political discourse may account for modifying the female speech style towards masculinity to achieve certain communicative aims.

    Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

    Studies have suggested associations between personality dimensions and body image constructs, but these have not been conclusively established. In two studies, we examined direct associations between the Big Five dimensions and two body image constructs, actual-ideal weight discrepancy and body appreciation. In Study 1, 950 women completed measures of both body image constructs and a brief measure of the Big Five dimensions. In Study 2,339 women completed measures of the body image constructs and a more reliable measure of the Big Five. Both studies showed that Neuroticism was significantly associated with actual-ideal weight discrepancy (positively) and body appreciation (negatively) once the effects of body mass index and social status had been accounted for. These results are consistent with the suggestion that Neuroticism is a trait of public health significance requiring attention by body image scholars. © 2012 The Authors.

O objetivo é entender o contexto social e cultural mais amplo no qual essa questão é mantida sob permanente tensão, em especial em razão de algumas mudanças que o marcam acentuadamente: a emergência de novos agrupamentos familiares que, por diferirem dos arranjos nucleares tradicionais, demandam um reordenamento das relações criança-adulto; a desterritorialização do capitalismo e sua concentração no consumo; a fragmentação da vida cotidiana; a construção de uma política de vídeo e a inversão sofrida nos âmbitos públicos e privados; o lugar central hoje ocupado pela mídia e a constatação de que há uma hegemonia das tecnologias eletrônicas e virtuais nos processos de comunicação, bem como a pulverização dos espaços de saber. Nesse contexto, os meios audiovisuais- entre eles a televisão - têm compartilhado cada vez mais com a família e com a escola sua função educativa, ocasionando para ambas um grande desconforto: faz-se necessário, mais do que nunca, repensar o lugar social que ocupam.This research has, as its main focus, the relationship established between child and publicity on TV.

    Full text: Current studies have been performed with the aim to find the correlation of radon concentration in the air and used construction materials. At the first stage of the measurements different samples of materials used in civil construction were studied as a source of radon in the air and at the second step it was studied the radon infiltration insulation using different samples of finishing materials. For 222 Rn concentration measurements related to different construction materials as well as for the studies of radon emanation and its reduction, the sealed cell chambers, of approximately 60 x 60cm 2 , have been built using the ceramic and concrete blocks. This construction has been performed within protected and isolated laboratory environment to maintain the air humidity and temperature stable. These long term measurements have been performed using polycarbonate alpha track passive detectors. The exposure time was set about 15 days considering previous calibration performed at the Institute of Radiation Protection and Dosimetry (IRD/CNEN), where the efficiency of 70% was obtained for the density of alpha particle tracks about 13.8 cm -2 per exposure day and per kBq/m 3 of radon activity concentration. The chemical development of alpha tracks has been achieved by electrochemical etching. The track identification and counting have been done using a code based on the MATLAB Image Processing Toolbox. The cell chambers have been built following four principle steps: 1) Assembling the walls using the blocks and mortar; 2) Plaster installation; 3) Wall surface finishing using the lime; 4) Wall surface insulation by paint. Making the comparison between three layers installed at the masonry walls from concrete and ceramic blocks, it could be concluded that only wall painting with acrylic varnish attended the expectation and reduced the radon emanation flow by the factor of 2.5 approximately.

    In general, image interpolation is required when the surface configurations of such structures as bones and organs are three-dimensionally constructed from the multi-sliced images obtained by CT. Image interpolation is a processing method whereby an artificial image is inserted between two adjacent slices to make spatial resolution equal to slice resolution in appearance. Such image interpolation makes it possible to increase the image quality of the constructed three-dimensional image. In our newly-developed algorithm, we have converted the presently and subsequently sliced images to distance images, and generated the interpolation images from these two distance images. As a result, compared with the previous method, three-dimensional images with better image quality have been constructed. (author)

    At Nuclear Regulatory Authority of the Slovak Republic (NRA SR), the public relations belongs to the secretariat of the Chairman, and are a part of the policy of carefully planned and purposeful efforts to establish mutual relations between the authority and the public. A spokesmen of NRA SR is in charge of the public relations. The spokesman is ready, without a useless filibuster and based on a particular requirement, to inform governmental bodies, other national bodies and organizations, embassies and international organizations, the public and news media in case of an event at a nuclear installation. To provide for communications activities, NRA SR constructed and opened the Information centre with a particular equipment in autumn 1995, that has already started communications with some dailies, broadcasting, television and Press Agency SR. It has been envisaged that there will be press conferences held in the Information centre a few times a year, or NRA SR senior staff may be interviewed here on extraordinary events at NPPs, or on some other important occasions in NRA SR. In 1995, NRA Sr issued the Annual report in a few variants - each suitable for different use - on NRA SR activities and nuclear safety of Slovak nuclear power plants as of 1994. The NRA SR's Bulletin has started to be published with periodicity of 3 times a year, focusing on NRA SR activities both in Slovakia and abroad. NRA SR Information centre provides foreign visitors with independent propagation and information materials about the issue of nuclear safety enhancement at operational Slovak NPPs. Furthermore, the Information centre provides both the NRA SR's residences in Bratislava and Trnava with daily press monitoring of topical news

    Full Text Available Russia and China are two big players in the international system, both of which share interests and concerns and compete for preponderance and affirmation at the regional level. As a framework for political-military cooperation, the Shanghai Cooperation Organisation (SCO frames this relationship in an institutional setting that might be understood as a tool for rapprochement between Moscow and Beijing or as a strategic manoeuvre for balancing an unbalanced international order. Thus the following question arises: is Russian-Chinese cooperation discourse mere political rhetoric or does it imply the intentional forging of a goal-orientated partnership? The relationship between Russia and China in political and security terms reveals identifiable common concerns, such as counter-terrorism or the fight against organised crime, while simultaneously masking the underpinning drivers, based on realpolitik dynamics and image construction on both sides (power projection, regional affirmation. This means that the strategic partnership dialogue between Moscow and Beijing is still far from being real. Realpolitik considerations rise above institutional goals, showing the lines of (discontinuity in discourse and practice in this bilateral relationship. Russland und China sind zwei wichtige Mitwirkende im internationalen System wobei sie dieselben Interessen und Bedenken teilen und im Wettbewerb um Vormachtstellung und Bestätigung auf regionaler Ebene stehen.

    This paper reports a receiver operating characteristic (ROC) experiment conducted to compare the diagnostic performance of a compressed bone image with the original. The compression was done on custom hardware that implements an algorithm based on full-frame cosine transform. The compression ratio in this study is approximately 10:1, which was decided after a pilot experiment. The image set consisted of 45 hand images, including normal images and images containing osteomalacia and osteitis fibrosa. Each image was digitized with a laser film scanner to 2,048 x 2,048 x 8 bits. Six observers, all board-certified radiologists, participated in the experiment. For each ROC session, an independent ROC curve was constructed and the area under that curve calculated. The image set was randomized for each session, as was the order for viewing the original and reconstructed images. Analysis of variance was used to analyze the data and derive statistically significant results. The preliminary results indicate that the diagnostic quality of the reconstructed image is comparable to that of the original image
