    1974-01-01

    After briefly describing the methods of production, radioactive, chemical and biological properties of californium-252, its health physics aspects are reviewed in detail. Its external and internal radiation hazards can be minimised through control of radiation and contamination and proper shield design. Use of various shielding materials is evaluated. The following aspects are also discussed : (1) radiation detectors for neutrons and gamma radiation (2) personnel monitoring techniques (3) bioassay and (4) storage and transportation. (M.G.B.)

    Martin, E.B.M.

    1982-01-01

    The health physics aspects of the use of tritium in university laboratories and similar establishments are considered. These aspects include discussion on the behaviour and hazards of tritium in the body, derived limits for contamination, monitoring methods, designation of workers, medical and dosimetric supervision, classification of laboratories, safety precautions, accidents and decontamination, and waste disposal. The radiation hazards from some special uses of tritium, e.g. tritium foil sources, luminous devices, gaseous light sources, are also considered. It was concluded that little harm is likely to come from careful handling of tritium labelled compounds at the millicurie level in a research laboratory. It would, however, be most unwise to be complacent about the use of tritium at the curie level, particularly when high specific activities, organic compounds and chronic exposure over long periods are involved.

    The sodium-potassium reactor coolant removed from the Experimental Breeder Reactor Number One after a partial reactor core meltdown had been stored at the Idaho National Engineering and Environmental Laboratory for 40 years. The State of Idaho considered this waste the most hazardous waste stored in the state and required its processing. The reactor coolant was processed in three phases. The first phase converted the alkali metal into a liquid sodium-potassium hydroxide. The second phase converted this caustic to a liquid sodium-potassium carbonate. The third phase solidified the sodium-potassium carbonate into a form acceptable for land disposal. Health physics aspects and dose received during each phase of the processing are discussed

    1978-01-01

    The EMI computerized tomographic cranial scanner is one of the first radiological systems incorporating an on-line computer. The result is an increase in the ability to visualize such tissues as grey matter and white matter as well as blood pools and tumor volumes. This advance has already begun to revolutionize radiological practice. Because of the totally different configuration of this unit, concern has been expressed over the dosages received by the patient, consequently the health physics aspects of this unit have been studied. Specifically, doses received by the surface of head and interior brain points as well as by the lens of the eye and gonads are reported here. X-ray output, beam half-value layers and barrier shielding requirements are also reported and discussed. (author)

    Full Text Available Aim: to analyze the state of physical education in secondary schools of Ukraine and to observe hygienic requirements during physical education lessons. Material: the study was attended by schoolchildren (n=40, age - 12-13 years and schoolchildren of specialized sports classes (n=40, age - 14-16 years. Studied: the level of physical health; functional state of the respiratory and cardiovascular systems; the state of energy supply of children’s organism; the influence of mobile games on the functional capabilities of the body of children. To study the effects of physical exercises on the development of the muscular system of children, excretion of creatinine with urine was studied. Results: high levels of physical and functional status of young players are noticed. These data are significantly higher than similar data from their peers from non-sports classes. In the course of systematic training and competitions, excretion of creatinine decreases at the end of the season to 0.8 g/l. These changes point to a decrease in energy resources and are consistent with a decrease in the rapid qualities of young players (as a measure of overall physical fitness. In this group of pupils, there were 2-4% lessons in the classes: mostly because of colds. In schoolchildren of ordinary schools, indicators of physical development and functional status were significantly worse. The indicators of the lung capacity were 3500-3800 ml. The distance of 30 m children ran for 5,5±0,4 seconds. The index of the brush dynamometer was 35±1,8 kg. The results of the recovery of the heart rate after the metered loading were from 2 to 3 minutes. There is a shortage of body weight in 12% of schoolchildren. There is an overweight in 1,8% of schoolchildren. Conclusions: in the structure of children’s morbidity a high level of respiratory diseases, gastrointestinal tract, and eyes is allocated. Therefore, when taking physical training, such data should be taken into account. It

    Much research is being carried out into indoor exposure to harmful agents. This review focused on the impact on children's health, taking a broad approach to the indoor environment and including chemical, microbial, physical and social aspects. Papers published from 2006 onwards were reviewed, with regards to scientific context. Most of publications dealt with chemical exposure. Apart from the ongoing issue of combustion by-products, most of these papers concerned semi volatile organic compounds (such as phthalates). These may be associated with neurotoxic, reprotoxic or respiratory effects and may, therefore, be of particular interest so far as children are concerned. In a lesser extent, volatile organic compounds (such as aldehydes) that have mainly respiratory effects are still studied. Assessing exposure to metals is still of concern, with increasing interest in bioaccessibility. Most of the papers on microbial exposure focused on respiratory tract infections, especially asthma linked to allergens and bio-aerosols. Physical exposure includes noise and electromagnetic fields, and articles dealt with the auditory and non auditory effects of noise. Articles on radiofrequency electromagnetic fields mainly concerned questions about non-thermal effects and papers on extremely low-frequency magnetic fields focused on the characterization of exposure. The impact of the indoor environment on children's health cannot be assessed merely by considering the effect of these different types of exposure: this review highlights new findings and also discusses the interactions between agents in indoor environments and also with social aspects.

The subjects were divided into three groups: residents of long-term care institutions (group I, residents of adult day-care homes (group II, and community-dwelling subjects (group III. Each group consisted of 100 subjects. Questionnaires evaluating the following physical and mental dimensions of health were used: SF-36 Health Survey, basic activities of daily living, instrumental activities of daily living, Geriatric Depression Scale, and Mini–mental state examination.Results: It was found that the health aspects of the elderly varied depending on whether care was provided in an institutionalized or a home environment, and the lowest health status was found in the elderly receiving in-home care. Furthermore, home-based elderly indicated significant limitations in performing basic activities of daily living and instrumental activities of daily living, as well as a higher prevalence of depression and cognitive impairment.Conclusion: The elderly in long-term institutionalized care, both in a residential home and adult day-care homes, were characterized by a better physical and mental health status than those receiving in-home care. It seemed that worse health status, including the more frequent depression occurrence and cognitive function disorders in the elderly using the nursing care at their homes

  11. Health physics aspects of the Yale Heavy Ion Linear Accelerator dismantling project

    Price, K.W.; Holeman, G.R.

    1976-01-01

    A program for the disassembly of the Yale Heavy Ion Linear Accelerator was initiated January 1, 1975. The object of the disassembly was to render the accelerator complex free of radioactive contamination in order that the area may be used for other University purposes. In addition, any salvage of metal parts was a desirable goal of the dismantling procedure. A systematic removal of all contaminated material began immediately. Portable survey instruments, swipe surveys, and sodium iodide gamma ray spectra were used as indicators of contamination. Apparatus in the direct beam line seemed to pose the most significant hazard to personnel. As beam components were eliminated, radioactive contamination was significantly reduced. Certain accelerator parts had to be machined in order to salvage non-contaminated metal, and the health physics aspects of this procedure are described. Isotopes found in the surveys included 22 Na, 54 Mn, 60 Co, 65 Zn and 75 Se, which were predominately beam activation products of accelerator components. Final surveys indicated the area free of radioactive contamination

    The aim of the work presented here was to explore differences between pet owners and non-pet-owners concerning aspects of health, physical/leisure activities, work and socio-demographics. The study was based on nationally representative data from the Swedish population (n = 43,589). Associations between pet ownership and background variables were investigated using logistic regression analysis. A total of 39,995 respondents were included in the analysis (non-pet-owners = 25,006; pet owners = 14,989). Pet ownership was associated with both positive and negative aspects of health, physical/leisure activities and socio-demographics. Pet owners had better general health but suffered more from mental health problems than non-pet-owners. Their leisure activities involved a greater interest in nature life and/or gardening than those of non-pet-owners. The logistic regression analysis showed that people who were self-employed, in the age range 35 to 49, of female sex, and suffering from pain in the head, neck and shoulders were more likely to own a pet than others. People physically active at a level sufficient to have a positive effect on their health more often owned a pet than people who were less active. Pet owners differ from non-pet-owners in aspects of socio-demographics, health, physical/leisure activities and work situation. This study, based on a general regional population in Sweden, showed differences of both a positive and a negative kind between non-pet-owners and pet owners concerning aspects of health, physical and leisure activities, and work situation.

    The Pacific Northwest Laboratory is conducting a comprehensive study of the impacts, benefits and effects of decontamination as a precursor to decommissioning for the US Nuclear Regulatory Commission. The program deals primarily with chemical cleaning of light-water reactor (LWR) systems that will not be returned to operation. A major section of this study defines the health physics and industrial hygiene and safety concerns during decontamination operations. The primary health physics concerns include providing adequate protection for workers from radiation sources which are transported by the decontamination processes, estimating and limiting radioactive effluents to the environment and maintaining operations in accordance with the ALARA philosophy. Locating and identifying the areas of contamination and measuring the radiation exposure rates throughout the reactor primary system are fundamental to implementing these health physics goals. The principal industrial hygiene and safety concerns stem from the fact that a nuclear power plant is being converted for a time to a chemical plant which will contain large volumes of chemical solutions

  17. Computerization aspects of the Health Physics' Radiation Control Program at Argonne National Laboratory

    1978-01-01

    Greater public awareness of the potential hazards of ionizing radiation and the more stringent governmental compliance programs have made accountability of radioactive materials an item of increasingly major concern for all radionuclide users. For low-volume (radioisotopically) organizations, manual record keeping techniques may suffice without requiring significant work-hour allocations. When considering high-volume users, the workload contingent with manual inventory is usually excessive from an employee time-allocation standpoint. Therefore, various automation systems are employed, usually with the aid of an in-house or time-purchase computer system. The computer programs developed for these systems often do not allow for future modification without major rewriting. Therefore, to facilitate in program concept, modification, and implementation the Health Physics Section at Argonne National Laboratory chose to design and code its computer program(s) and has instituted a Radiation Administrative Program (RAP) as a major component of the Section's laboratory-wide radiation control program. Coded in ANSI PL/I, RAP provides both flexibility in present concept and allowance for future growth. It requires less than 300K words of computer memory and can be easily incorporated at other organizations with minimal modifications. The modular design provides run cost benefits and versatility of report generation and modification. Through the use of this type of information processing and retrieval system, one can manipulate large amounts of radionuclide data, providing control and identification, while still maintaining commitment of computer costs and employee time at a reasonable level.

    People diagnosed with mental illness have shorter lives and poorer physical health, compared to the general population. These health inequities are usually viewed at an individual and clinical level, yet there is little research on the views of mental health consumers on clinical factors in broader contexts. To elicit the views of consumers of mental health services regarding their physical health and experiences of accessing physical health-care services. Qualitative exploratory design involving focus groups. The research was conducted in the Australian Capital Territory. Participants were consumers of mental health services. The Commission on Social Determinants of Health Framework was drawn on to lead deductive analysis of focus group interview transcripts. Issues impacting consumers included poverty, the neglect of public services and being treated as second-class citizens because of diagnosis of mental illness and/or experiencing a psychosocial disability. These factors were connected with significant barriers in accessing physical health care, including the quality and relevance of health provider communication, especially when the broader contexts of mental health consumer's lives are not well understood. These findings suggest the Commission on Social Determinants of Health Framework could be utilized in research and policy, and may provide an effective platform for exploring better health communication with mental health consumers regarding this neglected health inequity. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Full Text Available The aim of the research "Body image as a part of active life style" was to explore the meaning of several aspects of physical and psychological self and satisfaction with them. We are interested in the degree of meaning, satisfaction, control and chance for change. The article analyses the relation of 866 women (18-60 years old to their own body and health and to the own ideas and feelings. The monitored women feel considerable discrepancy between the importance of several items related to their body and psyche and between the satisfaction with them. The largest disproportion in the evaluation of importance and satisfaction was discovered at the life without fear, fright and tense (49 %. A big discrepancy was founded also at physical activities and fitness (32 %. The control over body and psyche perceive more than 60 % of the women, spirituality is a little more controlled than corporality. Contentment was evaluated less than control, opportunity and importance. More than 60 % of women showed dissatisfaction with the aspects of body and psyche. We have to learn to know the worth of our self and care of own progress in relation and limits of individual occasions. The satisfaction with the self is a ground of physical and psychological well - being.

    By means of semiotics it is studied, how it succeeds in quantum physics to make formulas plausible, the basic physical facts of which are not accessible for a common understanding respectively an understanding in the sense of classical physics. Thereby it deals with a generally acknowledged kind of making understandable of certain physical formulas beyond the individual marking distinctly of abilities of explaining and understanding of social phenomena and historical developments, whereby to these formulas each a certain experiment is put on side. The experiment is thereby such chosen that the physical phenomenon, which is described in the formula, is studied in the experiment, so that the formula then results as evaluation of the experiment.

    I am pleased to be able to attend this symposium in honor of D. Allan Bromley and to see the new accelerator of the Yale University Nuclear Structure Laboratory. My talk on symmetry tests seems appropriate for this occasion: so much of the progress in this field depends on detailed knowledge of nuclear structure. The nuclear ''tricks'' that are played to filter and amplify interactions are possible because the nuclear spectroscopists have cataloged nuclear levels and determined their properties. I will describe how such nuclear structure studies may help to provide a window on physics beyond the standard model. My talk is not a summary of this subfield of nuclear physics. There is simply too much happening today to make a summary talk feasible. Instead, I have chosen four topics that I hope are representative of the field as a whole: parity mixing of nuclear states, time-reversal-odd nuclear moments, the Mikheyev-Smirnov enhancement of solar neutrino oscillations, and a nuclear experiment to monitor the long-term rate of stellar collapse in the galaxy. 39 refs., 5 figs., 1 tab

    Transfer to a contract-bonus system in mines of the Severokuzbassugol' and Leninskugol' associations (USSR) increased coal mining productivity by 42.2-54.4%, but, at the same time, problems concerning miners' health were noted. Presents data on the productivity and labor conditions of contract teams working at coal mining and in development faces. The influence of noise and vibration induced stresses on organisms of underground workers is analyzed. Investigations showed that 3 stages of exhaustion are likely to develop and that the most vulnerable are the cardiovascular system and the respiratory tract. The 3 stages of exhaustion and ability to recover were studied on mining machine operators and drivers of heading machines. Data showed that during the 1985-89 period, 972 miners received disability certificates; the rate of disability was 2.6 miners per 1 Mt of coal; 40.5% of miners over 40 years working on labor-intensive jobs had three or more chronic diseases which could cause permanent disability. In the structure of disability, cardio-vascular system cases accounted for 25%, osseous-muscular system cases for 20% and pulmonary diseases for 13%. Stresses the need for every mine to maintain its own medical center equipped with inhalation therapy, psychological relief, acupuncture and physiotherapy facilities.

    General health aspects of carbon monoxide, lead, nitrogen oxides, unburned hydrocarbons, and aldehydes are described. Unlike spark ignition engines, diesel engines emit but minimal quantities of carbon monoxide. Automotive carbon monoxide may cause chronic poisoning by its combination with hemoglobin. The threshold value beyond which physiological changes occur lies at 2.5 percent carboxyhemoglobin. Nitric oxide, and especially nitrogen dioxide cause pulmonary edema, impaired respiratory function, and chronic bronchitis in very low concentrations. According to regulations implemented in France, a CO concentration of 40 ppM/hr must occur not more than 1 percent of the time on a yearly basis. A level of 15 ppm must not be exceeded for more than 15 percent of the time in any 9-hour period. The maximum allowable 1-hour nitrogen oxide concentration is set at 0.25 ppM. The emission standards implemented, as well as favorable meteorological conditions have resulted in an abatement of the CO concentrations in Paris.

    Fundamental Aspects of Plasma Chemical Physics - Thermodynamics develops basic and advanced concepts of plasma thermodynamics from both classical and statistical points of view. After a refreshment of classical thermodynamics applied to the dissociation and ionization regimes, the book invites the reader to discover the role of electronic excitation in affecting the properties of plasmas, a topic often overlooked by the thermal plasma community. Particular attention is devoted to the problem of the divergence of the partition function of atomic species and the state-to-state approach for calculating the partition function of diatomic and polyatomic molecules. The limit of ideal gas approximation is also discussed, by introducing Debye-Huckel and virial corrections. Throughout the book, worked examples are given in order to clarify concepts and mathematical approaches. This book is a first of a series of three books to be published by the authors on fundamental aspects of plasma chemical physics.  The next bo...

    Tosi, M.P.; Kornyshev, A.A.

    1991-01-01

    This volume collects the proceedings of the Working Party on ''Electrochemistry: Condensed Matter, Atomic and Molecular Physics Aspects'', held for two weeks in the summer of 1990 at the International Centre for Theoretical Physics (ICTP) in Trieste. The goal of the meeting was to discuss those areas of electrochemistry that are accessible to the modern methods of theoretical condensed matter, atomic and molecular physics, in order to stimulate insight and deeper involvement by theoretical physicists into the field. The core of the ICTP Working Party was a set of topically grouped plenary lectures, accompanied by contributed seminars and by the formulation of joint research projects. In the tradition of the ICTP, it was not a meeting of pure theoreticians: about half of the lecturers were professional experimentalists - experts in electrochemistry, physical chemistry, surface science, technical applications. A set of topics was chosen for discussion at the meeting: Liquids, solvation, solutions; The interface (structure, characterization, electric properties, adsorption); Electrodynamics, optics, photo-emission; Charge transfer kinetics (homogeneous and heterogeneous reactions and processes); Superconducting electrodes; Fractal electrodes; Applied research (energy conversion and power sources, electrocatalysis, electroanalysis of turbulent flows).

    International Nuclear Information System (INIS)

    Tolstoy, A.

    2002-01-01

    Full text: Conceptual approaches for designing an expert training program on object physical protection taking into account information security aspects are examined. A special educational course does not only address the immediate needs for an educational support but also ensures that new professionals include new concepts and knowledge in their practice and encourages current practitioners towards such practice. Features of the modern physical protection systems (PPS) and classification of information circulating at them are pointed out. The requirements to the PPS information protection subsystem are discussed. During the PPS expert training on information security (IS) aspects they should receive certain knowledge, on the basis of which they could competently define and carry out the PPS IS policy for a certain object. Thus, it is important to consider minimally necessary volume of knowledge taught to the PPS experts for independent and competent implementation of the above listed tasks. For the graduate PPS IS expert training it is also necessary to examine the normative and legal acts devoted to IS as a whole and the PPS IS in particular. It is caused by necessity of conformity of methods and information protection tools implemented on a certain object to the federal and departmental IS requirements. The departmental normative IS requirements define an orientation of the PPS expert training. By curriculum development it is necessary to precisely determine for whom the PPS experts are taught. The curriculum should reflect common features of the PPS functioning of the certain object type, i.e. it should be adapted to a certain customer of the experts. The specified features were taken into account by development of an educational course 'Information security of the nuclear facility physical protection systems', taught at the Moscow Engineering Physics Institute (State University) according to the Russian-American educational program 'Master in Physical

    Describing non-equilibrium "cold" plasmas through a chemical physics approach, this book uses the state-to-state plasma kinetics, which considers each internal state as a new species with its own cross sections. Extended atomic and molecular master equations are coupled with Boltzmann and Monte Carlo methods to solve the electron energy distribution function. Selected examples in different applied fields, such as microelectronics, fusion, and aerospace, are presented and discussed including the self-consistent kinetics in RF parallel plate reactors, the optimization of negative ion sources and the expansion of high enthalpy flows through nozzles of different geometries. The book will cover the main aspects of the state-to-state kinetic approach for the description of nonequilibrium cold plasmas, illustrating the more recent achievements in the development of kinetic models including the self-consistent coupling of master equations and Boltzmann equation for electron dynamics. To give a complete portrayal, the...

  3. Aspects of Landau condensation in atomic physics

    International Nuclear Information System (INIS)

    Gay, J.C.

    1980-01-01

    Some aspects of Landau condensation in atomic physics are reviewed both as regards current work on Rydberg states under laboratory conditions and from the viewpoint of the prospects of spontaneous decay of neutral vacuum with superheavy elements. The characteristics of the hydrogen-atom spectrum in a strong magnetic field are presented and discussed using essentially semiclassical arguments. Some schematic attempt at a global interpretation of the Rydberg spectrum near the ionization limit is also given. Then the action of an electric field on the quasi-Landau spectrum is discussed. The conditions for spontaneous production of positrons from neutral vacuum decay with superheavy elements are reconsidered for the case when the system experiences ultrastrong magnetic fields, as in pulsars and white dwarfs. It is shown that spontaneous decay of neutral vacuum may occur at lower Z values than 169. The possible importance of such effects during heavy-ion collisions is briefly discussed. We deal with some qualitative trends of the problem of an atom in a magnetic field with particular emphasis on diamagnetic effects. In the last few years, we have had the capability of making accurate experimental investigations of Rydberg atoms, and perhaps in the future we will develop fundamentally new means of studying heavy-ion collisions. Accordingly it seems of interest to make qualitative remarks regarding the present state of the problem and the possible importance of Landau condensation in various domains of atomic physics now under active development.

    Johnson, A.G.

    1970-01-01

    The factors influencing the complexity of a TRIGA health physics program are discussed in details in order to serve as a basis for later consideration of various specific aspects of a typical TRIGA health physics program. The health physics program must be able to provide adequate assistance, control, and safety for individuals ranging from the inexperienced student to the experienced postgraduate researcher. Some of the major aspects discussed are: effluent release and control; reactor area air monitoring; area monitoring; adjacent facilities monitoring; portable instrumentation, personnel monitoring. TRIGA reactors have not been associated with many significant occurrences in the area of health physics, although some operational occurrences have had health physics implications. One specific occurrence at OSU is described involving the detection of non-fission-product radioactive particulates by the continuous air monitor on the reactor top. The studies of this particular situation indicate that most of the particulate activity is coming from the rotating rack and exhausting to the reactor top through the rotating rack loading tube

  6. Nonlinear aspects of quantum plasma physics

    International Nuclear Information System (INIS)

    Shukla, Padma K; Eliasson, B

    2010-01-01

    Dense quantum plasmas are ubiquitous in planetary interiors and in compact astrophysical objects (e.g., the interior of white dwarf stars, in magnetars, etc.), in semiconductors and micromechanical systems, as well as in the next-generation intense laser-solid density plasma interaction experiments and in quantum X-ray free-electron lasers. In contrast to classical plasmas, quantum plasmas have extremely high plasma number densities and low temperatures. Quantum plasmas are composed of electrons, positrons and holes, which are degenerate. Positrons (holes) have the same (slightly different) mass as electrons, but opposite charge. The degenerate charged particles (electrons, positrons, and holes) obey the Fermi-Dirac statistics. In quantum plasmas, there are new forces associated with (i) quantum statistical electron and positron pressures, (ii) electron and positron tunneling through the Bohm potential, and (iii) electron and positron angular momentum spin. Inclusion of these quantum forces allows the existence of very high-frequency dispersive electrostatic and electromagnetic waves (e.g., in the hard X-ray and gamma-ray regimes) with extremely short wavelengths. In this review paper, we present theoretical backgrounds for some important nonlinear aspects of wave-wave and wave-electron interactions in dense quantum plasmas. Specifically, we focus on nonlinear electrostatic electron and ion plasma waves, novel aspects of three-dimensional quantum electron fluid turbulence, as well as nonlinearly coupled intense electromagnetic waves and localized plasma wave structures. Also discussed are the phase-space kinetic structures and mechanisms that can generate quasistationary magnetic fields in dense quantum plasmas. The influence of the external magnetic field and the electron angular momentum spin on the electromagnetic wave dynamics is discussed. Finally, future perspectives of the nonlinear quantum plasma physics are highlighted. (reviews of topical problems)

  7. Anthropological aspects of health psychology

    Directory of Open Access Journals (Sweden)

    Alexander V. Shuvalov

    2015-12-01

    Full Text Available The paper presents the results of a theoretical study carried out in the framework of the research project «Determinants of psychological health of the modern person». The issue of psychological health is considered in the context of the anthropological crisis that affects public body and causes a decrease in synergetic social life. On the level of specific manifestations, it is associated with damage to the spiritual and moral sphere, distortion of personal way of life and interpersonal relationships, which leads to a general decline in viability. A growing number of people, whose subjective state can be described as mentally fit, but personally sick is identified. Secondary symptoms of such conditions are depression, aggression, dependent behaviour. However, their essential characteristics are not captured by the existing social psychological, psychological pedagogical and medical psychological concepts and also do not fit the typical description of psychological emotional and/or behavioural disorders. The author adheres to the hypothesis that these states have specific spiritual and psychological conditions and symptoms that deserve scientific analysis and philosophical reflection. The leitmotif of the paper is the issue of mental health in its scientific and philosophical sense. Representation of health from the standpoint of modern humanitarian knowledge and traditional spiritual culture are generalized. The theory of general psychological health is developed. The main approaches to the problem of psychological health are presented. Comparative analysis of the humanistic and anthropological models of mental health is shown. Correspondence between the anthropological conditions and criteria of mental health concepts of the modern national educational ideal is presented. Educational activity is described as anthropological practice aimed at acquiring by a child the wide range of values as a person. As such, it is the most conducive to

    This book presents an introduction to aspects of ecology and has been quite purposefully restricted to the aspects of interest in connection with civil engineering and physical planning. The various chapters deal with soil, water bodies, air, plants and plant communities, trees in towns, animal life, noise and health, as well as high-energy radiation and its impact on man and environment. The book is intended to make engineers and other interested readers working in the technical professions familiar with ecologic principles and ecologically minded thinking in order to pave the way for ecology-mindedness in civil engineering and physical planning, hopefully contributing to avoiding mistakes and their harmful consequences.

  9. Mathematical and physical aspects of gauge theories

    International Nuclear Information System (INIS)

    Chatelet, G.; Paris-13 Univ., 93 - Saint-Denis

    1981-01-01

    We present here a survey of gauge theories, trying to relate the main mathematical and physical concepts. Part I is devoted to exhibiting parallel transport and connection as the adequate concepts for the constitution of the parametrized internal space of a particle. A covariant derivative provides the differential calculus, which is needed when one leaves the point-like description in microphysics. Part II deals with the so-called pure gauge theory and sketches the construction of the self-dual solutions of Yang-Mills equations. We briefly explain Guersey's method to get SU 2 self-dual potentials as quarternionic analytic maps from S 4 (first quarternionic projective space) into HPsub(n) (n-dimensional quarternionic projective space). Part III is devoted to the Goldstone's theorem and Higgs' mechanism used to provide a mass to gauge mesons. We describe a Salam-Weinberg model to illustrate these techniques. Part IV deals with the perturbative aspect. The Faddeev-Popov method, formerly conceived as a technique to get correct Feynmann rules, actually leads to a systematic study of the affine space of connections factored out by gauge transformations.

  12. Health aspects of cannabis: revisited.

    Science.gov (United States)

    Hollister, Leo E.

    1998-07-01

    Literature pertaining to the effects of cannabis use and health which has been published during the past 11 years has been reviewed. Many older concerns about adverse effects on health (chromosomal damage, 'cannabinol psychosis', endocrine abnormalities, cardiac events, impaired immunity) no longer seem to elicit much interest. Continuing concerns about the adverse cognitive effects of chronic use indicate that these can be demonstrated by proper testing; some studies suggest that they may be long-lasting. Although cannabis does not produce a specific psychosis, the possibility exists that it may exacerbate schizophrenia in persons predisposed to that disorder. However, evidence from retrospective surveys must always be questioned. Tolerance and dependence have occurred in man, confirming previous findings in many other species. Addiction tends to be mild and is probably less severe than with other social drugs. Driving under the influence of cannabis is impaired acutely; how long such impairments last is still unknown. More exacting tasks, such as flying an airplane, may be impaired for as long as 24 hours. While there is no doubt that marijuana smoke contains carcinogens, an increase in cancer among users has thus far been anecdotal. Because of the long latent period between cancer induction and initiation of cigarette smoking, the full story is yet to be told. Marijuana use during pregnancy is not advised although the consequences are usually not greater than those of smoking cigarettes, and far less than those from alcohol use. Whether smoked marijuana should become a therapeutic agent requires a cost-benefit analysis of the potential benefits versus the adverse effects of such use as we now know them.

  13. Health aspects of Antarctic tourism.

    Science.gov (United States)

    Prociv, P

    1998-12-01

    Increasing numbers of seaborne tourists are visiting Antarctica, with most coming from the United States (3503 in 1996-97), Germany (777), and Australia (680; cf. 356 in 1994-95 and 410 in 1995-96). The impression among travel medicine clinicians is that, each year, more prospective travelers seek advice about the health demands of this type of adventure, mostly relating to fitness for travel, exposure to extreme cold, hazards in ice and snow, and other potential health risks. This is a recent phenomenon. While a regular shipping service had been established between the Falklands and the subantarctic islands of South Georgia and the South Shetlands by 1924, the first documented tourists accompanied an Argentine expedition to the South Orkneys in 1933.1 Commercial airline flights over these islands and the Antarctic Peninsula began in 1956, from Chile, and recreational cruises to the Peninsula began in 1958. Tourist numbers subsequently grew slowly, for what was clearly an exclusive and very expensive undertaking, with few ships available for these hazardous voyages. From 1957 to 1993, 37,000 tourists visited by sea, most seeing only the Peninsula.2 The dramatic recent growth in numbers is a consequence of the collapse of the Soviet Union. The small fleet of ice-strengthened research vessels and working icebreakers, which was made redundant by withdrawal of central government support from isolated communities and military activities along the northern coast of Siberia (and from Antarctic research bases), now accounts for the bulk of charter-cruise tourism to Antarctica, at competitive prices. According to the International Association of Antarctica Tour Operators,3 7322 people traveled to Antarctica on commercially organized voyages in the 1996-97 season, and a record 10,000 shipborne visitors were expected for the 1997-98 season (November-March), traveling mainly from South America to the Peninsula on 15 ice-reinforced vessels, each carrying between 36 and 180

  14. Public health aspects of radiation

    International Nuclear Information System (INIS)

    Newcombe, H.B.

    1977-01-01

    The sources and levels of natural and manmade radiation are discussed in this report, and the resulting risks of radiation-induced cancer and hereditary diseases are estimated. The medical uses of X-rays currently increase the average population exposure by something like 35 per cent above natural background radiation. At a future time when nuclear generators will produce one kilowatt of electricity per person it is expected that the additional exposure from this source will not exceed 6 per cent of that from natural background. Acceptability of the risks that these exposures represent must depend upon the benefits with which they are associated, and upon the risks associated with other options open to society including alternative ways of obtaining similar benefits. The public health impact of the radiation from nuclear power generation, for example, is believed to be considerably less than that from the combustion products associated with the production of an equivalent amount of electrical power by conventional coal-fired stations.

    When dealing with radioactive material the health physicist receives innumerable papers and documents within the fields of researching, prosecuting, organizing and justifying radiation protection. Some of these papers are requested by the health physicist and some are required by law. The scope, quantity and deposit periods of the health physics documentation at the Karlsruhe Nuclear Research Center are presented and rationalizing methods discussed. The aim of this documentation should be the application of physics to accident prevention, i.e. documentation should protect those concerned and not the health physicist. (H.K.)

    The records that men have kept over the centuries have made the civilizations of man possible. Recorded history shows that our progress is closely correlated to man's ability to communicate recorded facts to others, and to effectively use knowledge gained by others. During the past few decades our ability to store and use information, and to reach larger audiences has grown dramatically. The advent of computers is discussed and their evolution to the state-of-the-art is described. Data bases, batch and on-line processing, centralized and distributed processing as well as other computer jargon are generally explained and examples are given as they apply specifically to health physics programs. It is proposed that systems designed to manage information cannot be adapted to health physics problems without extensive involvement of the HP who must use the computerized program. Specific problems which arise during the development of a computerized health physics program are explained

    Full text: The activities of the Health Physics Laboratory at the Institute of Nuclear Physics in Cracow are principally research in the general area of radiation physics, and radiation protection of the employees of the Institute of Nuclear Physics. Theoretical research concerns modelling of radiation effects in radiation detectors and studies of concepts in radiation protection. Experimental research, in the general area of solid state dosimetry, is primarily concerned with thermoluminescence (TL) dosimetry, and more specifically: development of LiF:Mg, Ti and CVD diamond detectors for medical applications in conventional and hadron radiotherapy and of LiF:Mg, Cu, P for low-level natural external ionising radiation. Environmental radiation measurements (cosmic-rays on aircraft and radon in dwellings and soil) are also performed using track CR-39 and TLD detectors. The Laboratory provides expert advice on radiation protection regulations at national and international levels. Routine work of the Health Physics Laboratory involves design and maintenance of an in-house developed TL-based personnel dosimetry system for over 200 radiation workers at the INP, supervision of radiation safety on INP premises, and advising other INP laboratories on all matters pertaining to radiation safety. We provide personal and environmental TLD dosimetry service for several customers outside the INP, mainly in hospitals and nuclear research institutes in Poland. We also calibrate radiation protection instruments for customers in southern Poland. The year 2000 was another eventful year for the Health Physics Laboratory. We started three new research projects granted by the Polish State Committee of Scientific Research. Mr P. Bilski co-ordinates the project on the measurements of radiation doses on board of commercial aircraft of Polish LOT Airlines. Dr B.

    Mass motions below the photosphere drive the solar cycle which is association with variations in the magnetic field structure and accompanying phenomena. In addition to semi-empirical models, dynamo theories have been used to explain the solar cycle. The emergence of magnetic field generated by these mechanisms and its expansions into the corona involves many plasma physical processes. Magnetic buoyancy aids the expulsion of magnetic flux. The corona may respond dynamically or by continually adjusting to a quasi-static force-free or pressure-balanced equilibrium. The formation and disruption of current sheets is significant for the overall structure of the coronal magnetic field and the physics of quiescent prominences. The corona has a fine structure consisting of magnetic loops. The structure and stability of these are important as they are one of the underlying elements which make up the corona. (Author)

    Primordial or big bang nucleosynthesis (BBN) is now a parameter free theory whose predictions are in good overall agreement with observations. However, the 7 Li calculated abundance is significantly higher than the one deduced from spectroscopic observations. Nuclear physics solutions to this lithium problem have been investigated by experimental means. Other solutions which were considered involve exotic sources of extra neutrons which inevitably leads to an increase of the deuterium abundance, but this seems now excluded by recent deuterium observations.

    Intraocular melanoma is the most common primary malignancy of the eye. Radiation therapy using ophthalmic plaque has proved successful in the management of various ocular lesions. Although a few centres were using 90 Sr/ 90 Y plaques for shallow turtlours some years ago, eye plaque therapy was not a common practice in India. A revived interest in the use of eye plaque therapy and very high cost of imported sources has led to the development and production of 125 I seed sources by the Radiopharmaceuticals Division, BARC. This report presents a brief description on the clinical, dosimetry and radiation safety aspects of 90 Sr/ 90 Y and 106 Ru/ 106 Rh beta ray and 125 I gamma ray eye plaque applicators. This report has been divided in five Sections. Section I presents general introduction of ophthalmic brachytherapy including the structure of a human eye, types of ophthalmic plaques and characteristics of radioisotopes commonly used in such applications. A brief review of sources, applicators and dosimetry of 90 Sr/ 90 Y and 106 Ru/ 106 Rh beta and 125 I gamma ophthalmic plaques are given in Section II and Section III, respectively. Section IV contains the single seed dosimetry data of BARC OcuProsta 125 I seed as well as dosimetry data of typical eye plaques loaded with BARC OcuProsta 125 I seed. Quality assurance and radiation safety aspects of these eye applicators are described in Section V. A proforma of the application required to be filled in by the user institution for obtaining regulatory consent to start eye plaque therapy has also been appended to this report. (author)

    A one-semester algebra-based physics course is being offered to Boston University students whose major fields of study are in allied health sciences: physical therapy, athletic training, and speech, language, and hearing sciences. The classroom instruction incorporates high-engagement learning techniques including worksheets, student response devices, small group discussions, and physics demonstrations instead of traditional lectures. The use of pre-session exercises and quizzes has been implemented. The course also requires weekly laboratory experiments in mechanics or electricity. We are using standard pre- and post-course concept inventories to compare this one-semester introductory physics course to ten years of pre- and post-course data collected on students in the same majors but who completed a two-semester course.

    In order to carry out the sort of probabilistic analysis referred to by Farmer (Contemp. Phys.; 22:349(1981)), it is necessary to have a good understanding of the processes involved in both normal and accident conditions in a nuclear reactor. Some of these processes, for a variety of different reactor systems, are considered in sections dealing with the neutron chain reaction, the removal of heat from the reactor, material problems, reliability of protective systems and a number of specific topics of particular interest from the point of view of physics or engineering.

    We consider the implications of current LHC data on new physics with strongly interacting sector(s). We parametrize the relevant interaction Lagrangian and study the best fit values in light of current data. These are then considered within a simple framework of bosonic technicolor. We consider first the effective Lagrangian containing only spin-0 composites of the underlying theory, which corresponds to a two Higgs doublet model. With respect to this baseline, the effects of the vector bosons, a staple in strong interacting theories, are illustrated by considering two cases: first, the case where the effects of the vector bosons arise only through their mixing with the electroweak SU(2){sub L} gauge fields and, second, the case where also a direct interaction term with neutral scalars exists. We find that the case with a direct coupling of the composite vector fields to the Higgs allows the tested model to fit the experimental results with goodness comparable to that of the SM.

    Post, D.; Bateman, G.; Houlberg, W.

    1986-11-01

    The Compact Ignition Tokamak (CIT) is a proposed modest-size ignition experiment designed to study the physics of alpha-particle heating. The basic concept is to achieve ignition in a modest-size minimum cost experiment by using a high plasma density to achieve the condition of ntau/sub E/ ∼ 2 x 10 20 sec m -3 required for ignition. The high density requires a high toroidal field (10 T). The high toroidal field allows a large plasma current (10 MA) which improves the energy confinement, and provides a high level of ohmic heating. The present CIT design also has a gigh degree of elongation (k ∼ 1.8) to aid in producing the large plasma current. A double null poloidal divertor and a pellet injector are part of the design to provide impurity and particle control, improve the confinement, and provide flexibility for impurity and particle control, improve the confinement, and provide flexibility for improving the plasma profiles. Since auxiliary heating is expected to be necessary to achieve ignition, 10 to 20 MW of Ion Cyclotron Radio Frequency (ICRF) is to be provided

    'Full-Text:' There is more to education in radiation protection than curricula, courses and certificates. In a broader sense, education implies the provision of knowledge, the development of competence, and the promotion of understanding. These purposes are served by 'Health Physics', the journal of radiation protection. The leading role of the journal is supported by an Advisory Board composed of members of the IRPA Publications Commission. A review is presented of the diversity of material in Health Physics throughout the last few years and set against the historical background. Expansion in the range of topics is described as well as the increase in didactic content both theoretical and operational. The global range of contributions is noted as is the attempt to provide an international perspective on developments in the discipline. Plans for the future are discussed. (author)

  16. Measuring physical neighborhood quality related to health.

    Although sociodemographic factors are one aspect of understanding the effects of neighborhood environments on health, equating neighborhood quality with socioeconomic status ignores the important role of physical neighborhood attributes. Prior work on neighborhood environments and health has relied primarily on level of socioeconomic disadvantage as the indicator of neighborhood quality without attention to physical neighborhood quality. A small but increasing number of studies have assessed neighborhood physical characteristics. Findings generally indicate that there is an association between living in deprived neighborhoods and poor health outcomes, but rigorous evidence linking specific physical neighborhood attributes to particular health outcomes is lacking. This paper discusses the methodological challenges and limitations of measuring physical neighborhood environments relevant to health and concludes with proposed directions for future work.

    The aim of this paper was to explore connection between aspects of self and levels of physical activity among adolescents. An international sample of 501 elementary school students (mean age 14.7 ± 0.9 years, 48.5% males) from the Slovak and Czech Republics completed the Self-competence/Self-liking Scale, the Rosenberg's Self-esteem Scale, the Self-efficacy Scale and a question on their physical activity. Respondents were divided into three groups: (1) no physical activity; (2) infrequent physical activity; (3) everyday physical activity. Data were explored with one-way analysis of variance (ANOVA) separately for each gender. Boys with no physical activity had lower self-liking and social self-efficacy in comparison with boys with everyday physical activity. Girls with no physical activity had lower positive self-esteem, self-liking, self-competence, general and social self-efficacy and higher negative self-esteem in comparison with girls with infrequent and everyday physical activity. Regular physical activity is connected with psychological aspects of self among adolescents, especially girls. Incorporating physical activity into the life of youths on a regular basis might lead to the enhancement of their feelings of self-worth and self-efficacy.

    We discuss aspects of antihydrogen studies, that relate to particle physics ideas and techniques, within the context of the ALPHA experiment at CERN's Antiproton Decelerator facility. We review the fundamental physics motivations for antihydrogen studies, and their potential physics reach. We argue that initial spectroscopy measurements, once antihydrogen is trapped, could provide competitive tests of CPT, possibly probing physics at the Planck Scale. We discuss some of the particle detection techniques used in ALPHA. Preliminary results from commissioning studies of a partial system of the ALPHA Si vertex detector are presented, the results of which highlight the power of annihilation vertex detection capability in antihydrogen studies.

    We study Higgs physics and related issues in the Standard Model (SM) and beyond. In the first part, we present theoretical predictions for Higgs pair production in the SM including higher order corrections in Quantum Chromodynamics (QCD) and the uncertainties on the respective cross sections from various sources. The second part covers supersymmetry. In the framework of the minimal supersymmetric extension of the SM, we investigate decays of light top squarks in the kinematic region where a flavour-changing decay into a charm or up quark and a neutralino or a four-body decay occurs. Furthermore, we discuss the Higgs sector in the next-to-minimal supersymmetric extension of the SM with complex parameters. In particular, we calculate the Higgs boson masses at one-loop order. In addition, we present Higgs boson production cross sections and decay widths. The third part introduces Composite Higgs Models as plausible candidates for physics beyond the SM. We calculate the leadingorder cross section for single and d...

    This paper advocates that mental health promotion receive appropriate attention within health promotion. It is of great concern that, in practice, mental health promotion is frequently overlooked in health promotion programmes although the WHO definitions of health and the Ottawa Charter describe mental health as an integral part of health. It is suggested that more attention be given to addressing the determinants of mental health in terms of protective and risk factors for both physical and mental conditions, particularly in developing countries. Examples of evidence-based mental health programmes operating in widely diverse settings are presented to demonstrate that well designed interventions can contribute to the well-being of populations. It is advocated that particular attention be given to the intersectorial cooperation needed for this work.

As part of this thesis, we suggest a number of activities that exploit this relationship.

  13. Nuclear physics aspects in the parton model of Feynman

    International Nuclear Information System (INIS)

    Pauchy Hwang, W.Y.

    1995-01-01

    The basic fact that pions couple strongly to nucleons has dominated various nuclear physics thinkings since the birth of the field more than sixty years ago. The parton model of Feynman, in which the structure of a nucleon (or a hadron) is characterized by a set of parton distributions, was proposed originally in late 1960's to treat high energy deep inelastic scattering, and later many other high energy physics experiments involving hadrons. Introduction of the concept of parton distributions signifies the departure of particle physics from nuclear physics. Following the suggestion that the sea quark distributions in a nucleon, at low and moderate Q 2 (at least up to a few GeV 2 ), can be attributed primarily to the probability of finding such quarks or antiquarks in the mesons (or recoiling baryons) associated with the nucleon, the author examines how nuclear physics aspects offer quantitative understanding of several recent experimental results, including the observed violation of the Gotfried sum rule and the so-called open-quotes proton spin crisisclose quotes. These results suggest that determination of parton distributions of a hadron at Q 2 of a few GeV 2 (and at small x) must in general take into account nuclear physics aspects. Implication of these results for other high-energy reactions, such as semi-inclusive hadron production in deep inelastic scattering, are also discussed

    1996-01-01

    Cellular mobile telephones are one of the main topics among health aspects of electromagnetic fields. In many countries, the number of people opposing communication towers is on the rise. Lawsuits against telecommunication and power line companies have been filed. All this makes people doubt the safety of electromagnetic fields. With respect to cellular phones, there are two scenarios: * Exposure of the operators of hand-held terminals (HHT). * Exposure of the general public from base stations (BS). In the first case, the transmit antenna of the HHT is very close to the human body. For normal operation, the distance will roughly be 2 - 3 cm. The transmitter power of the HHT is comparatively low, but there is a considerable fraction of the radiated electromagnetic energy penetrating the tissue. Considering the second case, BS transmitter powers are by a factor of 100-1000 higher, but the distance between antenna and the human body is by a factor of 1000-100,000 greater, as far as areas of unrestricted public access are concerned. As the power density of an electromagnetic wave decreases inversely proportional to the square of the distance, exposure of the public is always significantly (by many orders of magnitude) lower than exposure of operators of HHTs. Some well-known interaction mechanisms of microwave radiation with the human body have been very well-established today. In some other areas, there is still a need for further research. This paper summarizes present knowledge on human safety with mobile telephone systems. (author)

    ICRU Report No. 24 states that +- 5% is a reasonable degree of accuracy to strive for in the delivery of absorbed doses to target volumes in radiotherapy. To achieve this quality assurance level, a comprehensive programme comprising both physical and clinical components is needed. The purpose of this paper is to present the rationale and guidelines for implementing a recommended quality assurance programme. It will emphasize the physical aspects pertaining to acceptance and constancy tests using Cobalt-60 teletherapy units. It will also outline a suggested schedule of quality assurance testings including radiation dosimetry, geometry and electrochemical safety. (author).

    Full Text Available The article describes specific questions student learning inverse problems of mathematical physics. When teaching inverse problems of mathematical physics to the understanding of the students brought the information that the inverse problems of mathematical physics with a philosophical point of view are the problems of determining the unknown causes of known consequences, and the search for their solutions have great scientific and educational potential. The reasons are specified in the form of unknown coefficients, right side, initial conditions of the mathematical model of inverse problems, and as a consequence are functionals of the solution of this mathematical model. In the process of learning the inverse problems of mathematical physics focuses on the philosophical aspects of the phenomenon of information and identify cause-effect relations. It is emphasized that in the process of logical analysis applied and humanitarian character, students realize that information is always related to the fundamental philosophical questions that the analysis applied and the humanitarian aspects of the obtained results the inverse problem of mathematical physics allows students to make appropriate inferences about the studied process and to, ultimately, new information, to study its properties and understand its value. Philosophical understanding of the notion of information opens up to students a new methodological opportunities to comprehend the world and helps us to reinterpret existing science and philosophy of the theory related to the disclosure of the interrelationship of all phenomena of reality.

  20. Epidemiology applied to health physics

    International Nuclear Information System (INIS)

    1983-01-01

    The technical program of the mid-year meeting of the Health Physics Society, entitled Epidemiology Applied to Health physics, was developed to meet three objectives: (1) give health physicists a deeper understanding of the basics of epidemiological methods and their use in developing standards, regulations, and criteria and in risk assessment; (2) present current reports on recently completed or on-going epidemiology studies; and (3) encourage greater interaction between the health physics and epidemiology disciplines. Included are studies relating methods in epidemiology to radiation protection standards, risk assessment from exposure to bone-seekers, from occupational exposures in mines, mills and nuclear facilities, and from radioactivity in building materials

    The emphasis of Australian Government policy is on the promotion of good health in later life and positive experiences with ageing. Conceptually, a new gerontology framework has replaced the study of disease, decline, loss and disability. Within this framework, health promotion offers a mechanism by which individuals can be assisted to create environments that offer better opportunities for continued participation in society and improved quality of health and self-care. Oral health is instrumental to older people's health, life satisfaction, quality of life and perception of self. Australia is culturally diverse, composed of numerous ethno-cultural groups coexisting within a larger, predominant culture, creating a multicultural and multiracial society. However, despite this cultural diversity, the well documented ageing profile of the Australian population and repeated calls for comprehensive geriatric assessment, the oral health of older adults remains a challenge for oral health providers and for society. A major challenge will be to translate existing knowledge and experience of disease prevention and health promotion into appropriate programmes for older adults. Health promotion is the key to improving oral health in later life as it encourages older adults to be proactive in regard to their health. Therefore, increased efforts should be directed towards identifying opportunities for health promotion activities and the development of community based models that encourage older people to improve and maintain their oral health. Ignoring opportunities for health promotion may increase inequalities in oral health and may lead to even greater demands for curative and oral rehabilitative services from these groups This article firstly provides a brief rationale for oral health promotion. Its second part explores the influence of culture on health beliefs, behaviours and outcomes in older adults and how oral health can relate to cultural background. The last section

    Operational Health Physics can be comprised of a multitude of organizations, both corporate and at the plant sites. The following discussion centers around Baltimore Gas and Electric's (BG and E) Calvert Cliffs Nuclear Power Plant, located in Lusby, Maryland. Calvert Cliffs is a twin Combustion Engineering 825 MWe pressurized water reactor site with Unit I having a General electric turbine-generator and Unit II having a Westinghouse turbine-generator. Having just completed each Unit's ten-year Inservice Inspection and Refueling Outge, a total of 20 reactor years operating health physics experience have been accumulated at Calvert Cliffs. Because BG and E has only one nuclear site most health physics functions are performed at the plant site. This is also true for the other BG and E nuclear related organizations, such as Engineering and Quality Assurance. Utilities with multiple plant sites have corporate health physics entity usually providing oversight to the various plant programs

    Appropriate physical activity is one of the bases of healthy lifestyle. In fact, physical exercise and playing sport may be associated with both improvements and injury to both general and reproductive health. A biologically normal testosterone secretion appears fundamental in males to guarantee both a physiological exercise adaptation and safe sport participation. The reproductive system is highly sensitive to the effects of exercise-related stress and the reproductive hormones may both increase and decrease after different acute or chronic exercises. Exercise and sport participation may positively or negatively influence andrological health status depending on the type, intensity and duration of performed physical activity and on individual health status. In addition, prohibited substances administration (e.g. androgenic-anabolic steroids, and so forth) in competitive and non-competitive athletes represents the main cause of iatrogenic andrological diseases. Preventing and treating andrological problems in active healthy and unhealthy individuals is as important as promoting a correct lifestyle. Physicians need to be educated on the relationships between the male reproductive system and sport participation and on the great role of the pre-participation physical examination in the prevention of andrological diseases.

    Cross-border activities in health care in the European single market are increasing. Many of these cross-border developments are related to e-Health. E-Health describes the application of information and communication technologies across the whole range of functions that affect the health care sector. E-health attracts a growing interest on the European level that highlights the sharp need of appropriate regulatory framework able to ensure its promotion in the European Union. Some Directives constitute a step in this direction. Both the Data Protection Directive, the E-Commerce Directive, the Medical Device Directive and the Directive on Distance Contracting are some of the most important European legal achievements related to e-Health. Although the directives are not adopted especially for e-health applications, they are indirectly very important for e-Health. Firstly, the Data Protection Directive applies to personal data which form part of a filing system and contains several important principles that have to be complied with by e-Health actors processing personal data concerning health. Secondly, the E-commerce Directive applies to services provided at a distance by electronic means. Many e-Health applications fall within this scope. Thirdly, the Medical Devices Directive is of importance for the e-Health sector, especially with regard to e.g. the medical software that is used in many e-health applications. Finally, the Directive on Distance Contracting applies to contracts for goods or services which make use of one or more means of distance communication; E-Health business may involve the conclusion of contracts. Despite these Directives more developments are needed at the European level in order to make sure that e-Health will play an even more important role in health care systems than is the case today. The new e-Health applications like electronic health records, e-health platforms, health grids and the further use of genetic data and tissue involve new

    2011-02-01

    Patients' medical data have been originally generated and maintained by health professionals in several independent electronic health records (EHRs). Centralized electronic health records accumulate medical data of patients to improve their availability and completeness; EHRs are not tied to a single medical institution anymore. Nowadays enterprises with the capacity and knowledge to maintain this kind of databases offer the services of maintaining EHRs and adding personal health data by the patients. These enterprises get access on the patients' medical data and act as a main point for collecting and disclosing personal data to third parties, e.g. among others doctors, healthcare service providers and drug stores. Existing systems like Microsoft HealthVault and Google Health comply with data protection acts by letting the patients decide on the usage and disclosure of their data. But they fail in satisfying essential requirements to privacy. We propose a privacy-protecting information system for controlled disclosure of personal data to third parties. Firstly, patients should be able to express and enforce obligations regarding a disclosure of health data to third parties. Secondly, an organization providing EHRs should neither be able to gain access to these health data nor establish a profile about patients. Copyright © 2010 Elsevier Ireland Ltd.

    According to the final consensus of a panel of intense discussions, the health care system should/can not be excluded from the economic laws of efficiency. Appropriate adaptation of various methods and instruments of economics make these tools applicable for use in the health care system. Due to errors in the implementation of economic methods, though, the question arises who is economically responsible in the health care system. The answer is found at three different levels of the health care system. The physician plays a leading role, both personally and professionally, in being primarily responsible for the direct medical treatment of the patient. The physician's dependence, however, on the health care system reduces his independence, which markedly affects his decision-making and treatment. Management of and in health care institutions is largely independent of the profession learned. Managers and physicians acting as managers must be appropriately and duly educated in the necessary specific talents and knowledge. The organisation of a health care system should also be reserved for trained specialists where the physicians as well as other professionals are obliged to acquire the skills necessary.

    The ELMO Bumpy Torus (EBT) reactor has the advantage of high-β, steady-state operation. The first reactor study based on the EBT confinement concept was initiated in 1976. It provided the required starting point for continued assessment of the validity of the concept. A new design based on the present physics understanding, practical design approaches, and present and near-term technologies has been established. One of the important factors in an EBT reactor is the large aspect ratio (large toroidal major radius as well). This leads to a power plant with a comparatively large total energy output, usually in the range of 2000-6000 MW(th) for a conventional neutron wall loading of 1-2 MW/m 2 (the high value of β in an EBT device provides a net cost per unit energy roughly equal to or somewhat less than that for a Tokamak system). The large aspect ratio also provides very simple engineering and design requirements because of good access and small force loading asymmetries. Another important factor is the steady-state operation. In an EBT system, less power handling, energy storage, and filtering equipment will be needed. An EBT reactor is less likely to be subject to thermal and mechanical fatigue than reactors with large pulsed magnetic fields and short bursts of fusion power. The details of the key design elements and critical scientific and technology factors which are substantially different from other fusion reactor approaches are described

  15. Physics for Health in Europe

    CERN Multimedia

    CERN Bulletin

    Medicine increasingly relies on cutting-edge techniques for the early diagnosis and treatment of tumours and other serious diseases. The first “Physics for health in Europe” workshop will be held at CERN on 2-4 February 2010. It will aim to open the way to a European roadmap for using physics tools in the development of diagnostic techniques and new cancer therapies. Physics is not new to producing applications for life sciences. Several detection techniques are currently used in diagnosis instruments and hadron therapy is one of the most promising ways of treating tumours which cannot be treated with conventional irradiation techniques since they are either radio-resistant or located very close to critical organs.. However, despite this potential synergy, the two communities – physicists and medical doctors – do not often meet to plan common actions. The “Physics for Health in Europe” workshop is one of the first attempts to get both communities to...

    Kaferstein, F.

    1997-01-01

    Post-harvest losses due to sprouting, insect infestation and spoilage by microorganisms is a serious problem in many countries and commonly aggravates the problem of food shortages. In addition, many developing countries also depend largely on agricultural produce, such as grain, tuber and tropical fruit, as major export crops to earn foreign exchange. The use of ionizing radiation as an effective means of disinfecting and/or prolonging the self-life of several food products has been well documented in a number of developing countries. The World health organization (WHO) encourages its Member States to consider all measures to eliminate or reduce food borne pathogens in food and improve their supplies of safe and nutritious food. In regard to its contribution to food safety, food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection or limitation of this process may endanger public health and deprive consumers of the choice of foods processed for safety.

    2016-12-01

    This study aimed to map the selected indicators of health literacy in the senior population via a qualitative survey that focused specifically on its relationship with autonomy in the context of health literacy among seniors. A qualitative survey focused on the selected indicators of health literacy of seniors living in the South Bohemian Region of the Czech Republic (R1-19). The snowball sampling method was intentionally selected. Completed interviews were transcribed and data was reduced, analyzed, and categorized. The identified categories were 1) information comprehension, 2) decision-making in healthcare, and 3) compliance with nonpharmacologic treatment. The 'information comprehension' category clearly shows that the seniors involved in this study rated the comprehensibility of information provided by medical professionals as being good. An especially positive finding was that seniors do seek information through the internet, print sources, or other media, even though, as one senior (80-year-old woman) said, comprehension of medical information is becoming "more and more complex". The 'decision-making in healthcare' category touched upon opinions regarding informed consent and opinions regarding seniors' own involvement in healthcare. Results from this category suggest that seniors accept informed consent as a routine necessity. Inhibition regarding personal involvement in healthcare was also apparent: "... I come from a family accustomed to not bothering the doctor unnecessarily, so I just stick out my arm..." The last category of 'compliance with nonpharmacologic treatment' clearly shows that respondents are informed regarding lifestyle modifications that would benefit their treatment, although, few respondents had achieved the desired lifestyle changes. Results of this qualitative research show clear health literacy limits among seniors. As shown in this study, age itself could also be a limiting factor of health literacy.

    Full Text Available Introduction: The dynamic development of the automotive industry, transport, and the media means that human life has become much easier. At the same time, the comfortable living conditions have decreased physical activity. Biologically conditioned, the need of activity has been minimised by the ever-increasing pace of life. As a result, it may lead to the loss of physical and mental health. Active recreation is not only an excellent source of activity, but also a source of satisfaction. Youths and adults should therefore spend their free time primarily on various forms of physical activity. Aim of the research : To evaluate the physical fitness of students who regularly practice physical exercise, those who occasionally practice, and those not practicing any form of physical activity. Material and methods : In the research we used a questionnaire of the Ruffier test and an orthostatic test. The study involved a group of 15 people aged 20–25 years. Participation in the study was entirely voluntary and anonymous. The study group consisted only of women. Results obtained from the questionnaire survey were fully reflected during exercise tests performed. Results and conclusions: Only regularly practiced physical activity has an effect on our body. Regular exercise increases our body’s physical capacity. Activity is the best means of prevention of lifestyle diseases. Youths and adults should spend their free time mainly doing various forms of physical activity.

  3. Some health aspects of Canadian uranium mining

    1979-03-01

    The radiological health hazards associated with uranium mining in Canada are reviewed. Radiation hazards to individual members of the general population currently living in the vicinity of the mines appear to be extremely low. The major health hazards are those associated with underground mining. Hazards associated with the inhalation of radon daughters in the mines were estimated from analyses of available data from the U.S.A. and Czechoslovakia. These data can be fitted by various mathematical models including quasi-threshold models. On the reasonable assumption of a linear relationship between dose and effect, the risk would appear to be about 6.1 induced lung cancers per million WLM per year, which, averaged over a period of incidence of 15 years, would be equivalent to a total of about 100 induced cancers per million WLM. This value may be too high for estimation of the most probable risk of radon daughters to the general public. (author)

  4. Health aspects of air pollution in Dublin

    1975-01-01

    A study of the relationship between air pollution and specific health indicators in Dublin from 1970 to 1973 was undertaken using partial correlation analysis. Smoke and sulfur dioxide, accepted as indicators of general pollution conditions, were measured in the study. The indicators of health were deaths and hospital admissions of elderly and chronically ill people due to cardiovascular and respiratory illness, other than influenza and tonsillitis. Because temperature is also known to affect cardiovascular and respiratory illness, maximum daily temperature was chosen as the controlled weather variable. Mortality for cardiovascular disease was significantly correlated with SO/sub 2/ levels within the same 24 hr. Ischemic heart disease was the major component of this correlation. There is a progressive positive correlation at increasing threshold levels. These correlations were not sustained with a lag period of two days nor in relation to smoke indicators at any lag period or threshold level. Mortality for respiratory disease was less consistently associated with air pollution than cardiovascular disease. Levels of SO/sub 2/ up to 75 micrograms/cu m did not produce any significant response in terms of mortality. From 100 micrograms/cu m upwards there is a strong correlation with details from acute respiratory disease, principally acute bronchitis. At 150 micrograms/cu m threshold there is also a strong correlation with deaths from chronic bronchitis, emphysema and asthma. No significant correlations existed for smoke at any threshold or lag period. Implications for community health are discussed.

  7. Design and implementation of a radiotherapy programme: Clinical, medical physics, radiation protection and safety aspects

    International Nuclear Information System (INIS)

    1998-09-01

    It is widely acknowledged that the clinical aspects (diagnosis, decision, indication for treatment, follow-up) as well as the procedures related to the physical and technical aspects of patient treatment must be subjected to careful control and planning in order to ensure safe, high quality radiotherapy. Whilst it has long been recognized that the physical aspects of quality assurance in radiotherapy are vital to achieve and effective and safe treatment, it has been increasingly acknowledged only recently that a systematic approach is absolutely necessary to all steps within clinical and technical aspects of a radiotherapy programme as well. The need to establish general guidelines at the IAEA, taking into account clinical medical physics, radiation protection and safety considerations, for designing and implementing radiotherapy programmes in Member States has been identified through the Member States' increased interest in the efficient and safe application of radiation in health care. Several consultants and advisory group meetings were convened to prepare a report providing a basis for establishing a programme in radiotherapy. The present TECDOC is addressed to all professionals and administrators involved in the development, implementation and management of a radiotherapy programme in order to establish a common and consistent framework where all steps and procedures in radiotherapy are taken into account

    While health is defined as ‘a state of complete physical, mental and social well-being’, physical and mental health have traditionally been separated. This paper explores the question: How can physical and mental health promotion strategies be integrated and addressed simultaneously? A literature review on why physical and mental health are separated and why these two areas need to be integrated was conducted. A conceptual framework for how to integrate physical and mental health promotion st...

    The diagnosis of chronic kidney disease (CKD) in elderly individuals has been increasing. The objective of this study was to evaluate physical, mental and social aspects in longevous elderly patients with CKD. Eighty patients with CKD (stage 4 and 5, not on dialysis) and 60 longevous elderly (≥ 80 years) paired by gender and age living in the community were evaluated. Physical, cognitive, social and quality of life aspects were analyzed according to the following scales: Charlson comorbidity index, Medical Outcomes Study Short Form 36-Item (SF-36), Medical Outcomes Study, Boston Naming Test, verbal fluency test (animal naming), sit-to-stand test, gait speed, and the Mini-Mental state examination. Compared to the control group, the CKD group had a higher mean in the comorbidities index (3.5 ± 1.2 vs. 1.0 ± 1, respectively, p < 0.001). In the multivariate analysis, the CKD group presented worse performance in the SF-36 dimensions: 'physical functioning,' 'general health,' 'emotional functioning,' 'vitality,' and physical component summary. On the other hand, they presented better results for the 'mental health' dimension, in addition to lower  social support, worse verbal fluency and worse results on the sit-to-stand test. Longevous patients with stage 4 or 5 CKD presented worse evaluation in several domains of physical and emotional functioning, lower social support and evidence of worse cognitive performance. These aspects should be taken into account in order to improve the care provided to these patients, improve their quality of life and prevent their morbidity.

    Saforcada, E

    1976-09-01

    This paper reviews some general concepts on Planning, especially in public and welfare sectors, stressing those concerning the major flaws in the argentine system of mental health. The author considers the definition of planning levels, and sets forth three: general plan, program and project. The correlative implementation is also considered. The importance of feed-back from adequate evaluation is stressed, emphasizing three aspects: a) evaluation of dynamics, rate and extent of decrease, increase or stagnation; b) assessment of efficacity of factors involved; c) control and stabilization of goals already attained. The necessity to develop a human ecology, encompassing socio-cultural and psycho-social factors is stressed, together with fostering theoretical research and the use of its results by implementation agents. Several differences among prevailing mental health actions are pointed out which allow a distinction between two typical models: clinical and sanitarist. The main differences between them lye on: standard location of working sites, nature of basic actions, field of action, hypothesis for working, including ethiological and ecological assumptions, theoretical and methodological framework. A series of criteria for evaluating sanitary techniques and strategies are set forth, among which: operative procedures, length of treatments, degree of therapeutic concentration, and general pragmatic criteria. The indicators reviewed are: degree of efficacity, covering, degree of perseverance in treatments, cultural barriers between patient and therapist, delegation of functions into special, first-rate sanitary agents, needs for the training of mental health workers. An attempt is made at developping general evaluation criteria for mental health planning, and several indicators are proposed, among which: a) cost/efficacity ratio, including in costs the use of economical, human and physical resources; b) preventive capacities of the community; c) capacities for the

  16. Pet ownership and physical health.

    Matchock, Robert L

    2015-09-01

    Pet ownership and brief human-animal interactions can serve as a form of social support and convey a host of beneficial psychological and physiological health benefits. This article critically examines recent relevant literature on the pet-health connection. Cross-sectional studies indicate correlations between pet ownership and numerous aspects of positive health outcomes, including improvements on cardiovascular measures and decreases in loneliness. Quasi-experimental studies and better controlled experimental studies corroborate these associations and suggest that owning and/or interacting with a pet may be causally related to some positive health outcomes. The value of pet ownership and animal-assisted therapy (AAT), as a nonpharmacological treatment modality, augmentation to traditional treatment, and healthy preventive behavior (in the case of pet ownership), is starting to be realized. However, more investigations that employ randomized controlled trials with larger sample sizes and investigations that more closely examine the underlying mechanism of the pet-health effect, such as oxytocin, are needed.

    This article is a reflection on how interculturality, understood as the way to improve the health of the Bolivian population and coupled with the concept of living well, is not contributing to improving the quality of life and health of the most vulnerable populations in the country. The discourse is coupled with the intention of saving lives in its broadest sense; however, for this it is necessary to make decisions about environmental health and extractivist policies that are not taken into account in the health issues affecting indigenous communities, a population targeted by the intercultural aspects of the health reform.

  19. Health physics educational program in the Tennessee Valley Authority

    Holley, Wesley L.

    1978-01-01

    In the spring of 1977, the Radiological Hygiene Branch of the Tennessee Valley Authority (TVA) instituted a training program for health physics technicians to ensure availability of qualified personnel for the agency, which is rapidly becoming the world's largest nuclear utility. From this, a health physics education program is developing to also include health physics orientation and retraining for unescorted entry into nuclear power plants, health physics training for employees at other (non-TVA) nuclear plants, specialized health physics training, and possibly theoretical health physics courses to qualify technician-level personnel for professional status. Videotaped presentations are being used extensively, with innovations such as giving examinations by videotape of real-life, in-plant experiences and acted out scenarios of health physics procedures; and teaching health physics personnel to observe, detect, and act on procedural, equipment, and personnel deficiencies promptly. Video-taped lectures are being used for review and to complement live lectures. Also, a 35-mm slide and videotape library is being developed on all aspects of the operational health physics program for nuclear plants using pressurized and boiling water reactors. (author)

    The aim of this manuscript was to review the knowledge about leptin, detailing its relationship with energetic intake and physical activity. Leptin is an adipocyte hormone, recognized mainly for its putative role in control of energy expenditure, food intake, body weight and reproductive function. Leptin has still important peripheral actions, including its role on the ovarian tissue. The intracellular signaling mechanisms are recognized in hypothalamus, but in peripheral tissue are not fully understood. The exercise, when practiced by women, if not appropriately planned according to food intake, can modify the leptin release. When energy imbalances induced by exercise and/or deficient food ingestion occurs, low leptin levels are observed, leading to a reduction in GnRH (gonadotropin-release hormone), in LH (luteinizing hormone) and FSH (follicle-stimulating hormone) in pituitary, and consequently a minor release of ovarian estrogens. This process is named hypothalamic amenorrhea, and has repercussions in the woman's health. In this perspective, it is important to emphasize the need to evaluate the energy expenditure from exercise and to formulate adequate alimentary plans to these individuals.

  1. New directions in health physics

    International Nuclear Information System (INIS)

    Vaughan, B.E.

    1975-04-01

    Present statutory and other requirements placed on health physics groups include many areas besides that of radiological monitoring. It is not unusual for health physics groups to also monitor metal contamination and accidental release of certain toxic chemicals. The general approach in terms of medical surveillance, monitoring, sampling, and measurement technology will be applicable outside the nuclear area. With the creation of the U.S. Energy Research and Development Administration, and with abolition of the former U.S. Atomic Energy Commission, it is clear that technologies beyond strictly nuclear technology will be implemented to meet energy needs of the next decade. The impact of some of these technologies for electric power production on the environment are discussed with emphasis on coal. It is pointed out that coal consumption can be expected to increase, and the scale of operation for individual plants can be unbelievably large. The contributions of nuclear power plants and fossil fuels to meet energy demands by the year 2000 are estimated. Both health and environmental implications of such operations are discussed in relation to anticipated research and monitoring programs. (U.S.)

    In the annual report No.26 (fiscal 1983) are described the activities of health physics including radioactive waste management in Tokai Research Establishment, Takasaki Radiation Chemistry Research Establishment and Oarai Research Establishment. In all the three research establishments, radiation monitoring in nuclear facilities, individual monitoring, environmental monitoring and maintenance of measuring instruments were carried out as in the previous years. There were no occupational exposures exceeding the maximum permissible doses and no releases of radioactive gaseous and liquid wastes beyond the release limits specified according to the regulations. In the environment there were observed no abnormal radioactivities due to facilities. (J.P.N.)

    By means of semiotics it is studied, how it succeeds in quantum physics to make formulas plausible, the basic physical facts of which are not accessible for a common understanding respectively an understanding in the sense of classical physics. Thereby it deals with a generally acknowledged kind of making understandable of certain physical formulas beyond the individual marking distinctly of abilities of explaining and understanding of social phenomena and historical developments, whereby to these formulas each a certain experiment is put on side. The experiment is thereby such chosen that the physical phenomenon, which is described in the formula, is studied in the experiment, so that the formula then results as evaluation of the experiment.

    To identify the aspects of working in Australian primary health care that nurses rate as the most and least satisfying. The nursing workforce in Australian primary health care has grown exponentially to meet the growing demand for health care. To maintain and further growth requires the recruitment and retention of nurses to this setting. Understanding the factors that nurses' rate as the most and least satisfying about their job will inform strategies to enhance nurse retention. A cross-sectional online survey. Nurses employed in primary health care settings across Australia were recruited (n = 1166) to participate in a survey which combined items related to the respondent, their job, type of work, clinical activities, job satisfaction and future intention, with two open-ended items about the most and least satisfying aspects of their work. Patient interactions, respect, teamwork, collegiality and autonomy were identified as the most satisfying professional aspects of their role. Personal considerations such as family friendly work arrangements and a satisfactory work-life balance were also important, overriding negative components of the role. The least satisfying aspects were poor financial support and remuneration, lack of a career path, physical work environment and time constraints. National restructuring of the primary health care environment was seen as a barrier to role stability and ability to work to a full scope of practice. This study has identified a range of positive and negative professional and personal aspects of the primary health care nursing role, which may impact on staff recruitment and retention. Findings from the study should be considered by employers seeking to retain and maximise the skills of their primary health care workforce. Understanding the factors that nurses perceive as being the most and least satisfying aspects of the work is can open up dialogue about how to improve the working experience of nurses in primary health care.

    The whole universe is intermingling into a unit in the period of globalization. Different cultures, life-styles and sciences are co-operating with each other in this situation. World Health Organization is working towards collaborating all prevalent medical sciences for attainment of good health and family welfare for each and every individual by 2020. Astrology is a part of Indian heritage. Astrology means the art of predicting or determining the influence of the planets and stars on human affairs. The origin of this word is from Greek word astron, star + logos (discourse). The account of deeds of good and bad during the present life and previous lives, their consequences of health or ill health during this life i.e. what, when and how the things takes place will be clearly known through Astrology. Highly advanced knowledge related to Astrology on medicine is preserved in Indian scriptures and the knowledge was transmitted from generation to generation. It is also a good source for health promotion, preventive, curative and other medical aspects. Brief direction related to astrological medical aspects is also available in Ayurvedic literature (Carakasamhită, Suśrutasamhhită, Aşţăngasangraha, Aşţăngahŗdaya, Sărngadharasamhită , Băvaprakăśa etc.) Some Ayurvedic practitioners, scholars and scientists realize the need of astrological knowledge related to medicine in the present time. In ancient times physician, astrologer and purŏhita (Hindu priest) simultaneously looked after the health and family welfare of individual, families and country. Astrologer guides medication and suitable time for the better cure of ailments. Even the medicinal herbs were collected and treated at appropriate time for their efficacy. Astrology and Ayurvĕda are inseparable sciences of life. Hence, in this article, a concise astrological evaluation related to health promotion, preventive and curative aspects of Astrology is being presented.

    2017-06-01

    Mental and physical aspects are both integral to health but little is known about the dynamic relationship between them. We consider the dynamic relationship between mental and physical health using a sample of 11,203 individuals in six waves (2002-2013) of the English Longitudinal Study of Ageing (ELSA). We estimate conditional linear and non-linear random-effects regression models to identify the effects of past physical health, measured by Activities of Daily Living (ADL), and past mental health, measured by the Centre for Epidemiological Studies Depression (CES-D) scale, on both present physical and mental health. We find that both mental and physical health are moderately state-dependent. Better past mental health increases present physical health significantly. Better past physical health has a larger effect on present mental health. Past mental health has stronger effects on present physical health than physical activity or education. It explains 2.0% of the unobserved heterogeneity in physical health. Past physical health has stronger effects on present mental health than health investments, income or education. It explains 0.4% of the unobserved heterogeneity in mental health. These cross-effects suggest that health policies aimed at specific aspects of health should consider potential spill-over effects.

  10. Operational Health Physics-Science or Philosophy?

    Carter, M. W.

    2004-01-01

    Operational health physics is concerned with protecting workers and the public from harm due to ionizing radiation. This requires the application of philosophy (ethics) as well as science. Operational health physics philosophy has been dominated by the ICRP. A particular aspect of ICRP's philosophy that is often misunderstood is (As low as reasonably achievable, economic and social factors being taken into account). (ALARA) Although the ALARA philosophy has been interpreted as a cost-benefit approach it is in fact a risk-benefit approach including social considerations as the ICRP has emphasised from time to time. A recent report has accused the ICRP of using a discarded philosophical approach, namely Utilitarianism, as a result of which its recommendations are unethical. The report suggests that a (rights) based philosophy such as Rawls' Theory of Justice would be a more appropriate basis. This paper discusses this accusation, considers some relevant philosophies and concludes that the accusation is not valid and that ICRP's recommendations are ethical but are frequently misinterpreted.

    Full Text Available This article was elaborated in order to analyze issues relating to the judicialization of cases involving health, understanding health as a public policy aimed at to guarantee the fundamental right to it linked, that is, the concept of health that the authos intended to work is not far from that contained in the combined reading of Articles 6 and 196 of the Constitution, consecrators to be the health, universal right and duty of the state, guaranteed through social and economic policies aimed at to reduce the risk of disease and other becomes, ensuring also the universal and equal access to actions and services for its promotion, protection and recovery. With this approach it is intended to analyze the feasibility and consequences of judicial control of social and economic policies of promotion, protection and recovery, access, anyway, the effective flow to the fundamental right. Relating to the methodological aspects employed in the analysis of the issue concerning to the health, it was searched in the interpretation of constitutional provisions that secure the subjective right the starting point of the analysis as well as the unwavering appreciation of inseparability of judicial control in the context of public policy, assessing possible limits of the judicial branch, and then to realize a brief analysis of previous trial in the Supreme Court and extract from this jurisprudencial context the minimum goals for aspects of health judicialization.

    2003-01-01

    Closed macromolecular chains may form physically knotted conformations whose relative occurrence and spatial measurements provide insight into their properties and the mechanisms acting upon them. Under the assumption of a degree of structural homogeneity, equilateral spatial polygons are a productive context within which to create mathematical models of these knots and to study their mathematical and physical properties. The ensembles, or spaces, of these knots are models of the settings within which the knots evolve in ways determined by a physical model. In this paper we describe the mathematical foundation of such models as well as such spatial, geometric, statistical, and physical properties of the configurations as mathematical energies, thickness and ropelength, average crossing number, average writhe, and volumes and surfaces areas of standard bodies enclosing the knots. We present methods with which the energy and ropelength are optimized within the families of spatially equivalent equilateral configurations. Numerical results from our implementation of these methods are shown to illustrate connections between the physical measurements and spatial characteristics of the optimized knot configurations. In addition, these data suggest potentially new connections involving their spatial properties

    The public is aware that nuclear reactors can be made to operate, so this paper treats reactor lattice and core physics as briefly as possible before proceeding to the physical principles of reactor control which currently seems of more public concern. First the role of delayed fission neutrons in slowing down the exponential divergence of a super-critical reactor is outlined. Next the physical basis of the various components of the power coefficient of reactivity is explained together with the methods of adjusting this coefficient toward the desired value. Finally, longer-term reactivity effects are discussed with emphasis on the several effects of Xe-135 'poison' on reactor design and operation. (author)

    Military and social restrictions imposed on Japanese scientific research following the second world war made nuclear or particle physics experiments almost impossible. However, the (Japanese) theoretical achievements of the 1940s considerably buoyed this group, namely two-meson theory, super-many-time theory and covariant renormalization theory. Economic conditions were also difficult with high inflation throughout the 1950s. Printing and distribution problems and paper shortages reduced the circulation of scientific journals, but theoretical work progressed well even in isolation. Within Japan, a circular called Soyrushiron Kenkyu (elementary particle theory research) became a valuable medium for exchange of new ideas and information. A Research Institute for Fundamental Physics, the first of several Japanese research institutes, was opened at Kyoto University in 1953, when a major international conference was held there. The second half of the 1950s was a time of expansion and consolidation for particle physics in Japan. (UK)

This study draws together statements on this phenomenon made in a discourse context hitherto dominated by theoreticians and philosophers of science and points up new perspectives of an interdisciplinary nature discussed here primarily from the viewpoint of cognitive semantics. How do metaphors enter into a discourse with physics? To what extent are the methods used and the issues addressed in physics influenced by metaphors? How do the ubiquitous metaphors of ever

    Full Text Available I discuss possible connections between several scales in particle physics and cosmology, such the the electroweak, inflation, dark energy and Planck scales. In particular, I discuss the physics of extra dimensions and low scale gravity that are motivated from the problem of mass hierarchy, providing an alternative to low energy supersymmetry. I describe their realization in type I string theory with D-branes and I present the main experimental predictions in particle accelerators and their implications in cosmology. I also show that low-mass-scale string compactifications, with a generic D-brane configuration that realizes the Standard Model by open strings, can explain the relatively broad peak in the diphoton invariant mass spectrum at 750 GeV recently reported by the ATLAS and CMS collaborations.

    Full Text Available The article discusses organizational and legal aspects of electronic health information exchange in developed countries, particularly, introduction of electronic medical records in the United States and Europe, as well as topical issues related to standardization of information technologies in health care. We briefly describe the most popular standards used in e-medicine, such as Digital Imaging and Communications in Medicine (DICOM, openEHR and HL7. The questions of syntactic and semantic interoperability in the exchange of electronic medical records and some aspects of the digital signature use are also considered. We suggest mechanisms for implementation of electronic document management and sharing of digital medical information, as one of the most important directions of information technologies in health care. It is noted that today, the main limiting factor in providing the digital exchange of health information in Russian Federation is unresolved legal issues, i.e. the absence of a legal framework of electronic medical records share. At the same time, the level of IT development in our country is quite sufficient to meet current challenges. It is stated that, despite the unresolved number of problems (for example, completeness of medical data on a patient, given to relatives in critical situations, the adoption of a single electronic card is able to bring medical care to a new level, especially in emergency and urgent medicine.

  3. Health physics operations in hospitals

    The special problems of applying the basic principles of radiological protection in the environment of a hospital are outlined, the hospital being not only a workplace but also the temporary home of the patients. In these circumstances, close co-operation is needed between all groups of hospital staff. Many technical innovations have been made over the past 50 years in the applications of both ionizing and non-ionizing radiation for diagnosis and therapy and, at the present time, an intensive development of these applications is in progress. Within that context, the role of health physics has become a major one. There is the need to provide high standards in radiological protection of the staff, of members of the public, and increasingly, of the patient. At the same time, there is the need to provide sound perspective on hazards arising from exposure to various forms of radiation, whether ionizing or non-ionizing, for that perspective will influence future developments in this field.

    In the annual report No. 22 (fiscal 1979) are described the activities of health physics including radioactive waste management in Tokai Research Establishment, Takasaki Radiation Chemistry Research Establishment and Oarai Research Establishment. In all the three research establishments, radiation monitoring in nuclear facilities, individual monitoring, environmental monitoring and maintenance of measuring instruments were carried out as in previous years. There were no occupational exposures exceeding the maximum permissible doses and no release of radioactive gaseous and liquid wastes beyond the release limits specified according to regulations. In the environment there were observed no abnormal radioactivities due to facilities. In Tokai and Oarai Research Establishments radioactive waste management including decontamination works was also carried out and radioactive solid wastes were stored in the same way as in previous years. Construction of the Packaged Waste Storage Facility was completed, and of the Facility of Radiation Standards and the Medium-Level Waste Treatment Facility progressed on schedule in Tokai Research Establishment. In Oarai Research Establishment, construction was completed on the latter project of radioactive waste treatment facilities, starting in 1974. Technical development and research were made as in previous years for improving techniques and methods in monitoring of individuals, facilities and environment and also in waste management and decontamination.

  5. Physical aspects of heavy charged particle beams for radiotherapy

    International Nuclear Information System (INIS)

    Kawashima, Katsuhiro

    1989-01-01

    Physical properties of heavy ion beams are discussed to improve the physical dose distributions in view of radiotherapy. Preservation of the structural and functional integrity of adjacent normal tissue is required to achieve great probability of tumor control. This will be accomplished with the reduction of irradiated volume of normal tissues and with greater relative biological effectiveness (RBE) on tumor cells than that on surrounding normal cells. This suggests the use of heavy ion beams as new source of radiation that increases the therapeutic ratio. The basis of the improvement in the physical dose distribution by use of heavy charged particles is due to the finite range of the beams and to the less multiple coulomb scattering of the particles having a heavier atomic mass than proton. The depth dose distributions and dose profiles of heavy particle beams are discussed in this article. The lateral sharpness of heavy charged particles is comparable to the penumbra of high energy photon and electron beams and is not of clinical concern due to less coulomb scattering of heavy ions to lateral direction in traversing a medium. The dose gradient at the end of range of primary beam is dependent upon the energy spread and range straggling of the particles. The magnitude of range straggling is nearly proportional to the range and inversely proportional to the inverse square root of the particle mass. Heavy ion beams also undergo nuclear interactions, in which the primary beam may produce lower atomic number particles. Therefore, the dose beyond the Bragg peak is due to those fragments. Fragmentation increases as a function of the atomic mass to the 2/3 power and with the energy of the particles. Thus, the production of fragments diminishes the depth dose advantages of heavy ions. The choice of ion for radiotherapy may depend on evaluation of important parameter for tumor control. (J.P.N.)

    To explore nurses' views on the role of nurses in screening and monitoring for physical care of consumers with serious mental illness, at a regional mental health care service. People with serious mental illness experience heightened incidence of preventable and treatable physical illnesses such as cardiovascular disease and diabetes. Screening and monitoring are considered universal clinical safeguards. Nurses can potentially facilitate systematic screening, but their views on physical health care practices are rarely investigated. Qualitative exploratory study. Focus group interviews with 38 nurses of a regional mental health care service district of Australia. To facilitate discussion, participants were presented with a screening system, called the Health Improvement Profile (HIP), as an exemplar of screening of physical health risks by nurses. Inductive data analysis and theme development were guided by a thematic analysis framework. Nurses argued that treatable and preventable physical health problems were common. Four main themes were identified: screening - essential for good practice; the policy-practice gap; 'screening then what?' and, is HIP the answer? Screening and monitoring were considered crucial to proper diagnosis and treatment, however, were not performed systematically or consistently. Nurse readiness for an enhanced role in screening was shaped by: role and responsibility issues, legal liability concerns, funding and staff shortages. Participants were concerned that lack of follow up would limit effectiveness of these interventions. Screening was considered an important clinical step in effective diagnosis and treatment; however, identified barriers need to be addressed to ensure screening is part of a systemic approach to improve physical health of consumers with serious mental illness. Nurses have potential to influence improvement in physical health outcomes for consumers of mental health services. Such potential can only be realised if a

    The purpose of this report is to describe the physical operations which take place within the petroleum and natural gas industries of the US. This information was the basis for the overall network design and the detailed data requirements for the Emergency Management Information System (EEMIS) of the US Department of Energy (DOE). Since EEMIS represents the entire oil and gas systems this report can be used to obtain a basic understanding of the entire energy system, from production to consumption, that is composed of the US oil and gas industries.

  8. The 5th ATLAS Physics Workshop in Rome: Social Aspects

    CERN Multimedia

    Ferrari, P.

    Rome, the political and cultural capital of Italy, hosted the 5th ATLAS Physics Workshop. The attendance of this workshop was larger than any expectation: 450 people participated, making it a great success in terms of informing the broadest possible audience about the achievements of the physics groups in the last two years. The workshop took place at AULA MAGNA of the Literature & Philosophy faculty of the University of Roma Tre. The conference room was bright and large and could easily accommodate the wide audience, and the discomfort of hours of sitting was nicely offset by the frequent coffee breaks with excellent sweets and a large variety of drinks, which always seemed to offer the chance to stand up just in time! Participants listening to a talk in Aula Magna. The workshop started on Monday 6th June 2005 around 12:00 with the registration procedures, followed by a light lunch that was served (as was practically every lunch during the week) just outside the conference room.

    The present work studied the viability of gamma radiation as alternative method of conservation 'minas frescal' cheese through by determining its effect on the physical-chemical properties of this product after irradiation. Cheese elaborated in the Laboratory of Food Irradiation CENA/USP, were exposed to doses of 0 (it controls); 1; 2; 3 and 4 kGy and stored under refrigeration (±5 deg C). The analysis were accomplished in the 1st, 7th and 14th day of storage considered the following parameters: acidity, pH, moisture and level of proteolysis according to methodology of Association of Official Analytical Chemists (A.O.A.C.),1995. The results revealed that the dose of 2 kGy was the most indicated for irradiation of that type of cheese, because after this treatment, the product maintained in good conditions for consumption after 14 days of storage. It was concluded that gamma radiation can be used as a method of conservation of 'minas frescal' cheese, without causing alterations in its physical-chemical characteristics. (author)

    For the storage of BWR fuel elements in a high density fuel rack using boronated steel absorbers and in a fuel rack with a larger pitch without absorber, criticality calculations are performed. The cooling water density is varied for the storage without absorbers. For the selected pitches of 16.5 cm for the high density fuel rack and 25 cm for the fuel rack without absorber respectively the ksub(infinitely) values of 0.933 and 0.748 are obtained. The dependence of the results on different calculational methods and on the influence of the variation of three important design parameters, i.e. of the concentration of boron, of the thickness of the boronated steel and of the watergap is investigated for the high density fuel rack. The average isothermal temperature coefficient is obtained for the high density fuel rack as -4.5 x 10 -40 sup(0)C -1 and as approx. 2.0 x 10 -40 sup(0)C -1 for the fuel rack without absorbers. For both ways of storage the aspects of safety of the results are discussed thoroughly. (orig.) 891 RW/orig. 892 CKA [de

    This is a summary of the proceedings of the Conference on the Health Aspects of the Tsunami Disaster in Asia that was convened by the World Health Organization in Phuket, Thailand from 04-06 May 2005. It contains reviews of the experiences of the health sector and early recovery following the Earthquake and Tsunami with emphasis on what was done well and what could have been done better and the lessons learned that can be incorporated into actions that will mitigate the damage created by future events. It outlines the national and international responses and recovery and the actions taken and not taken by the international community in support of the countries affected. Specific issues addressed include: (1) needs assessments; (2) coordination; (3) filling gaps in essential services, and (4) capacity building at the country level. Each of these aspects is analyzed as to its: (1) appropriateness; (2) adequacy; (3) effectiveness; (4) efficiency; and (5) connectedness. Much of what occurred provided benefits to the stricken population, but there is substantial room for improvement through implementation of the lessons learned. These lessons must be converted into actions in order to mitigate the damage sustained and to enhance our responses to the damage from future events.

    Recent progress in experimental and theoretical studies of edge localized mode (ELM) physics is reviewed for the reactor relevant plasma regimes, namely the high confinement regimes, that is, H-modes and advanced scenarios. Theoretical approaches to ELM physics, from a linear ideal magnetohydrodynamic (MHD) stability analysis to non-linear transport models with ELMs are discussed with respect to experimental observations, in particular the fast collapse of pedestal pressure profiles, magnetic measurements and scrape-off layer transport during ELMs. High confinement regimes with different types of ELMs are addressed in this paper in the context of development of operational scenarios for ITER. The key parameters that have been identified at present to reduce the energy losses in Type I ELMs are operation at high density, high edge magnetic shear and high triangularity. However, according to the present experimental scaling for the energy losses in Type I ELMs, the extrapolation of such regimes for ITER leads to unacceptably large heat loads on the divertor target plates exceeding the material limits. High confinement H-mode scenarios at high triangularity and high density with small ELMs (Type II), mixed regimes (Type II and Type I) and combined advanced regimes at high beta p are discussed for present-day tokamaks. The optimum combination of high confinement and small MHD activity at the edge in Type II ELM scenarios is of interest to ITER. However, to date, these regimes have been achieved in a rather narrow operational window and far from ITER parameters in terms of collisionality, edge safety factor and beta p . The compatibility of the alternative internal transport barrier (ITB) scenario with edge pedestal formation and ELMs is also addressed. Edge physics issues related to the possible combination of small benign ELMs (Type III, Type II ELMs, quiescent double barrier) and high performance ITBs are discussed for present-day experiments (JET, JT-60U, DIII-D) in

    Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and fast transport and charge extraction to counter recombination processes. Ferroelectric materials are able to host a permanent electrical polarization which provides control over electrical field distribution in bulk and interfacial regions. In this review, we provide a critical overview of the physical principles and mechanisms of solar energy conversion using ferroelectric semiconductors and contact layers, as well as the main achievements reported so far. In a ferroelectric semiconductor film with ideal contacts, the polarization charge would be totally screened by the metal layers and no charge collection field would exist. However, real materials show a depolarization field, smooth termination of polarization, and interfacial energy barriers that do provide the control of interface and bulk electric field by switchable spontaneous polarization. We explore different phenomena as the polarization-modulated Schottky-like barriers at metal/ferroelectric interfaces, depolarization fields, vacancy migration, and the switchable rectifying behavior of ferroelectric thin films. Using a basic physical model of a solar cell, our analysis provides a general picture of the influence of ferroelectric effects on the actual power conversion efficiency of the solar cell device, and we are able to assess whether these effects or their combinations are beneficial or counterproductive. We describe in detail the bulk photovoltaic effect and the contact layers that modify the built-in field and the charge injection and separation in bulk heterojunction organic cells as well as in photocatalytic and water splitting devices. We also review the dominant families of ferroelectric materials that have been most extensively investigated and have provided the best photovoltaic performance.

  18. Physical aspects of sensory transduction on seeing, hearing and smelling.

    2013-01-01

    What is the general principle of sensory transduction? Sensory transduction is defined as energy transformation from the external world to the internal world. The energy of the external world, such as thermal energy (heat), electro-magnetic energy (light), mechanical energy (sound) and the energy from molecules (chemicals), is converted into electrochemical events in the animal nervous system. The following five classes of special sense receptors are utilized for energy conversion: vision (photo); audition (sound); taste and smell (chemo); and tactile (mechano). There are also other special sense receptors, including thermo and noxious receptors. The focus of this study is on photoreceptors, sound-receptors and odorant-receptors because the transduction mechanisms of these receptors are explained biochemically and understood by a common physical principle; these biochemical models are well known in neuroscience. The following notable problems are inherent in these biochemical models: the cGMP ionophore model of the vertebrate photoreceptor cannot explain the fast photo-response (∼msec); the tip links connection model of stereocilia in the basilar membrane for opening the K(+) channel on the tip of a hair has difficulty explaining the high frequency vibration of hair cells without a damping of the oscillation, and the odorant shape-specific receptor model for olfactory transduction has difficulty in discriminating the minute differences among similar fragrant smells of essential oils with different molecular shapes. These difficulties might arise from a lack of the physical sense when the transduction models were proposed. This article will reconsider these problems and propose rational models for visual, olfactory and auditory transduction.

  19. Physics aspects of recent and future concepts in radiotherapy

    Georg, D.

    Full text: The development of 3-D conformal radiotherapy (3D-CRT), in which the high dose volume matches as closely as possible the target volume and avoids therefore normal tissue irradiation as far as possible, has been a major theme in radiotherapy for improving the therapeutic window. Conformal radiotherapy is not a new concept but only the technological improvements of the last decade allow its clinical implementation. More recent and advanced forms of 3D-CRT are intensity modulated radiotherapy (IMRT) and stereotactic radiotherapy (SRT). IMRT uses an additional degree of freedom to achieve a new class of conformation: the variation of the primary beam intensity. SRT is based on a three dimensional stereotactic coordinate system which is correlated with the patient and the treatment facility through modern imaging technology. IMRT and SRT are related by common features, e.g. high dose gradients and small fields which require a high geometric precision. A high dosimetric and geometric precision can only be based on a detailed knowledge of the patient specific anatomy. Therefore, IMRT and SRT need to underlie multi-modality imaging studies. Both IMRT and SRT utilize photon beams and multiple field arrangements which increase the volumes of healthy tissue receiving low doses. Photons have a low selectivity along the beam direction implying that the sharp dose gradients are to be compromised. The increased low dose volume as well as the low selectivity of photon beams can be over-come by using proton or ions. Brachytherapy, a form of radiotherapy where encapsuled radioactive sources are placed directly in or in the vicinity of the tumor, is by definition conformal. Endovascular brachytherapy has become a promising new field in radiotherapy for the prevention of (re)stenosis after angioplasty. Although many clinical trials have been performed during the last years specific aspects related to endovascular brachytherapy have not been addressed clearly, such as the

    The safety analysis of lead-cooled fast reactors has been performed for the well-developed concept of BREST-OD-300 reactor. The most severe accidents have been considered. An ultimate design-basis accident has been defined as an event resulting from an external impact and involving a loss of leak-tightness of the lead circuit, loss of forced circulation of lead and loss of heat sink to the secondary circuit, failure of controls and of reactor scram with resultant insertion of total reactivity margin, etc. It was assumed in accident analysis that the protective feature available for accident mitigation was only reactivity feedback on the changes in the temperatures of the reactor core elements and coolant flow rate, and in some cases also actuation of passive protections of threshold action in response to low flow rate and high coolant temperature at the core outlet. It should be noted that the majority of the analyzed accidents could be overcame even without initiation of the above protections. It has been demonstrated that a combination of inherent properties of lead coolant, nitride fuel, physical and design features of fast reactors will ensure natural safety of BREST and are instrumental for avoiding by a deterministic approach the accidents associated with a significant release of radioactivity and requiring evacuation of people in any credible initiating event and a combination of events.

    AVN is a licensed body that performs health physics control in different types of installations, from large nuclear facilities to small dentist cabinets. AVN can also provide medical physics services for the quality control of, for instance, medical devices used in a radiology or nuclear medicine department. Radiation protection for personnel and environment (health physics) and radiation protection for the patient (medical physics) are usually treated separately, using different referential documents, such as the European Directives 96/29/Euratom for health physics and 97/43/Euratom for medical physics. This difference is also clearly reflected in the Belgium legislation (two types of accreditation/licence for inspectors, different chapters in the law,..) From a practical point of view it is sometimes rather difficult to split the task 'on site' during an inspection. An RX system not complying with radiation protection criteria can definitively affect the patient as well as the workers. On the other hand, the hospitals, cannot easily differentiate these two tasks because they are not fully aware of the legislation and they are mixing both. Taking into account the health physics guidelines as well as medical physics guidelines, we have decided to move to an integrated approach of these two concepts. (orig.)

    Some previous studies have reported that survivors of childhood cancer are at an increased risk of developing long-term mental health morbidity, whilst others have reported that this is not the case. Therefore, we analysed 5-year survivors of childhood cancer using the British Childhood Cancer Survivor Study (BCCSS) to determine the risks of aspects of long-term mental health dysfunction. Within the BCCSS, 10 488 survivors completed a questionnaire that ascertained mental health-related information via 10 questions from the Short Form-36 survey. Internal analyses were conducted using multivariable logistic regression to determine risk factors for mental health dysfunction. External analyses were undertaken using direct standardisation to compare mental health dysfunction in survivors with UK norms. This study has shown that overall, childhood cancer survivors had a significantly higher prevalence of mental health dysfunction for 6/10 questions analysed compared to UK norms. Central nervous system (CNS) and bone sarcoma survivors reported the greatest dysfunction, compared to expected, with significant excess dysfunction in 10 and 6 questions, respectively; the excess ranged from 4.4-22.3% in CNS survivors and 6.9-15.9% in bone sarcoma survivors. Compared to expected, excess mental health dysfunction increased with attained age; this increase was greatest for reporting 'limitations in social activities due to health', where the excess rose from 4.5% to 12.8% in those aged 16-24 and 45+, respectively. Within the internal analyses, higher levels of educational attainment and socio-economic classification were protective against mental health dysfunction. Based upon the findings of this large population-based study, childhood cancer survivors report significantly higher levels of mental health dysfunction than those in the general population, where deficits were observed particularly among CNS and bone sarcoma survivors. Limitations were also observed to increase

  4. Physical Activity and Health in Preschool Children

    Christensen, Line Brinch

    Physical activity is beneficial in relation to several life style diseases and the association between physical activity and early predictors of life style diseases seem to be present already in preschool age. Since physical activity and other health behaviours are established during childhood...... and track from childhood into adult life, it is relevant to address physical activity already in the preschool age. The research in preschool children’s physical activity is relatively new, and because of methodological inconsistencies, the associations between physical activity and health are less clear...... in this age group. The objective of this thesis was to contribute to the knowledge base regarding physical activity in preschoolers; How active are preschoolers? Are activity levels related to specific settings during a typical week? And are the activity levels related to a range of health outcomes...

    In response to projected demands for health physics personnel with field training at the bachelor's degree level, the Bionucleonics Department has revised its curriculum in Radiological Health to provide applied training in health physics. The basic program provides a strong background in math, physics, chemistry and biology and an in-depth background in the fundamentals of health physics and field training in applied health physics. The field training is also open to graduate students. The field exercises are coordinated with Purdue's Radiological Control Program and include such tasks as contamination and direct radiation surveys; facility and personnel decontamination; reactor, accelerator, and analytical and diagnostic X-ray monitoring; instrument calibration; personnel monitoring; and emergency planning and accident evaluation. In a weekly discussion period associated with the field exercises, the students evaluate their field experience, discuss assigned problems, and receive additional information on regulations, regulatory guides, and management of radiation protection programs

    Full Text Available Functional foods have been identified as whole foods and fortified, enriched, or enhanced products which have a potentially beneficial effect on health when consumed as part of a varied diet on a regular basis, at effective levels. As consumer awareness on functional food escalates, the interest towards conducting scientific studies in this field has also proportionately increased. Many of the traditional food products are known to possess bioactive components, thus qualifying as functional food. Kombucha tea is produced by fermenting sugared black tea with a mixed culture of yeast and bacteria. Kombucha tea has gained immense popularity in recent times due to many associated health benefits. The therapeutic effects of this beverage are thought to be derived from the chemical composition of this beverage, mainly the polyphenols and secondary metabolites which are produced during fermentation. However, the safety aspects of the beverage also need to be taken into account when qualifying the beverage as a functional food. Nevertheless, Kombucha tea could be easily recognized as a beverage which is able to replace the consumption of carbonated beverages due to its possession of health benefits and therapeutic properties.

    1983-01-01

    For the past decade, the demand for health physics personnel, at both the professional and technical levels, has been increasing, and indeed has become quite acute in recent years. The need for health physics personnel is demonstrated by a summary of projected requirements and potential candidates by the year 1991. Suggestions made for ensuring the availability of qualified health physics personnel includes: 1) a characterization study of health physicists should be conducted, with emphasis on industry, to determine qualifications, job satisfaction factors, and other data pertinent to entry and retention in the field; 2) the curricula currently offered by post-secondary schools should be evaluated for quality and relevance; and 3) an industry standard or protocol for qualification and training of health physics should be developed and implemented

    2018-03-01

    The purpose of the research is to analyze specific problems of the realization of the right to protect the health of people who take narcotic drugs or psychotropic substances. To achieve this goal, statistics have been analyzed on the number of people using narcotic drugs or psychotropic substances (including drug-addicted children) placed on medical records and the number of their applications for medical care. It has been found out that people in this category often face a denial of medical care that causes extremely strong physical and mental suffering. The analysis of the understanding of the legal design of the «right to health care» in the scientific literature, national legislation and international legal documents was made. State institutions and local authorities providing «the right to health care» of people taking narcotic or psychotropic drugs are singled out. The absence of grounds for restricting the right to protect the health of people who take narcotic or psychotropic drugs who are not registered is justified. In the course of the research, it was found out that people who take narcotic drugs or psychotropic substances are more likely than other patients to need medical assistance and, when requesting the right to health care, face a number of problems that require immediate solution: incomplete provision of quality free medical care; unimplementation of rehabilitation programs for such categories of patients; the lack of the right of children who take narcotic drugs or psychotropic substances to make their own decisions at the age of 14 and apply to public health institutions for the treatment of drug addiction; violations of the continuity of SMT programs and their absence in penal institutions for drug dependent people. It was proposed to introduce a number of changes in the relevant normative legal acts.

  16. The forces that shape embryos: physical aspects of convergent extension by cell intercalation

    International Nuclear Information System (INIS)

    Keller, Ray; Shook, David; Skoglund, Paul

    2008-01-01

    We discuss the physical aspects of the morphogenic process of convergence (narrowing) and extension (lengthening) of tissues by cell intercalation. These movements, often referred to as 'convergent extension', occur in both epithelial and mesenchymal tissues during embryogenesis and organogenesis of invertebrates and vertebrates, and they play large roles in shaping the body plan during development. Our focus is on the presumptive mesodermal and neural tissues of the Xenopus (frog) embryo, tissues for which some physical measurements have been made. We discuss the physical aspects of how polarized cell motility, oriented along future tissue axes, generate the forces that drive oriented cell intercalation and how this intercalation results in convergence and extension or convergence and thickening of the tissue. Our goal is to identify aspects of these morphogenic movements for further biophysical, molecular and cell biological, and modeling studies

    1991-01-01

    The impacts on power reactor health physics programs form implementing the revised 10 CFR Part 20 will be extensive and costly. Every policy, program, procedure and training lesson plan involving health physics will require changes and the subsequent retraining of personnel. At each power reactor facility, hundreds of procedures and thousands of people will be affected by these changes. Every area of a power reactor health physics program will be affected. These areas include; ALARA, Respiratory Protection, Exposure Control, Job Coverage, Dosimetry, Radwaste, Effluent Accountability, Emergency Planning and Radiation Worker Training. This paper presents how power reactor facilities will go about making these changes and gives possible examples of some of these changes and their impact on each area of power reactor health physics program

    Ng, V; Norwood, A

    2000-09-01

    The aim of this review is to examine the relationship between trauma, physical health and somatisation. A search was made on the Procite Database at the Department of Psychiatry at the Uniformed Services University of the Health Sciences for research articles with the following key words: posttraumatic stress disorder, somatisation, trauma (the Procite Database holds more than 15,000 articles related to trauma and disaster). A review of the current research findings show a link between prior exposure to traumatic events (such as war, disaster, motor vehicles and industrial accidents, crime and sexual assault, domestic violence and child abuse) and subsequent physical heath and medical care utilisation. Possible mechanisms and conceptualisations which may explain the association between trauma and physical health, such as high-risk health behaviours, neurobiology, alexithymia and culture are discussed. Because traumatised persons show high medical utilisation, good screening, thorough assessment, empirically-based treatment and appropriate referral of such patients are essential.

    Full Text Available Training programs that include aerobics and strength exercises, either at the same session or alternate days are defined as concurrent training (CT. The objective of this study was to verify the effects of a CT program on biochemical parameters,cardiovascular fitness, body composition and neuromuscular aspects. Twenty two elderly women physically active were randomly allocated to one of the five groups: AS (aerobic exercises followed by strength training; n=5, SA (strength activities followed by aerobics exercises; n=5, AG (aerobics exercise only;n=5, SG (strength activities only; n=4, CG (control group; n=3. The program lasted 12 weeks. Tests of dynamic and static strength, flexibility, aerobic power, body composition and biochemical parameters were conducted. In the aerobics power test, AS and SA groups showed differences in the post-test compared to the CG. In dynamic strength test of upper limbs, the groups S, SA, AS showed statistical differences from the CG in the post-test (p=0.009, 0.006 and 0.002 respectively. Only the AS group presented some difference from the pre to post-tests (P=003. AG, SG, SA, AS showed differences in the post-test inrelation to the CG for the lower limbs strength test (p<0.001. From pre to post-test within the same group, the groups SG, SA and AS showed differences (p=0.001, 0.03, 0.02. Stretching, static strength, biochemical factors and body composition showed no association with any of the groups. We concluded that CT was equivalent to the strength and aerobics exercises performed exclusively.

    O'Connell, Brenda H; Killeen-Byrt, Mary

    2018-04-29

    There is now a growing body of research demonstrating the physical health benefits of being grateful. However, research has only just began to explore the mechanisms accounting for this gratitude-health relationship. This study examines the relationship between dispositional gratitude and self-reported physical health symptoms, and explores whether this relationship is explained through reduced levels of perceived loneliness and stress. This study employed a cross-sectional design with a sample of 607 healthy adults. Serial mediation analysis revealed that the positive effect of gratitude on physical health was significantly mediated by lower reported levels of perceived loneliness and stress. These findings are important given evidence that gratitude can be cultivated, and may serve to buffer against stress and loneliness and improve somatic health symptoms in the general population.

  15. Public health aspects of the available electricity sources

    International Nuclear Information System (INIS)

    Rabl, A.; Spadaro, J.V.

    2000-01-01

    This paper presents a summary of recent studies of the safety of energy systems, presenting the results both in physical units of YOLL (years of life lost) and in monetary units. Whereas the earlier studies of the safety of energy systems tended to focus on risks to workers and on accidents, in recent years the importance of public health impacts due to pollution has been recognized, especially thanks to the ExternE (External Costs of Energy) Project of the European Commission. To evaluate the impact and damage cost of a pollutant, one needs to carry out an impact pathway analysis; this involves the calculation of increased pollutant concentration in all affected regions due to an incremental emission (e.g. μg/m 3 of particles, using models of atmospheric dispersion and chemistry), followed by the calculation of physical impacts (e.g. number of cases of asthma due to these particles, using a dose-response function). The entire so-called fuel chain (or fuel cycle) is evaluated and compared on the basis of delivered end use energy. Even though the uncertainties are large, the results provide substantial evidence that the classical air pollutants (particles, NOx and SOx) from the combustion of fossil fuels impose a heavy toll, in addition to the cost of global warming. The external costs are especially large for coal; even for 'good current technology' they may be comparable to the price of electricity. For natural gas the external costs are about a third to a half of coal. The external costs of nuclear are small compared to the price of electricity (at most a few %), and so are the external costs of most renewable energy systems. (authors)

    1995-01-01

    The last Construction Permit to be issued by the U.S. Nuclear Regulatory Commission (NRC) for a U.S. light water reactor (LWR) was granted in the late 1970s. In 1989 the NRC issued 10 CFR Part 52 which is intended to serve as a framework for the licensing of future reactor designs. The NRC is currently reviewing four different future on open-quotes next-generationclose quotes reactor designs. Two of these designs are classified as evolutionary designs (modified versions of current generation LWRs) and two are advanced designs (reactors incorporating simplified designs and passive means for accident mitigation). These open-quotes next-generationclose quotes reactor designs incorporate many innovative design features which are intended to maintain personnel doses ALARA and ensure that the annual average collective dose at these reactors does not exceed 100 person-rems (1 person-sievert) per year.

After their useful life, SPNDs are replaced and are disposed off in Tile holes. The Cobalt SPNDs having activity in the range of 35 to 160 TBq were encompassed in carbon steel canister. The canister having dose 25 to 50 Sv/h at 1 meter were transported in shielded flask for disposal in specially designed Tile hole at Solid Waste Management Facility (SWMF) at Tarapur. To keep personal exposures As Low As Reasonably Achievable (ALARA) the disposal operation was carried out remotely from a shielded cabin placed at a distance of 50 meter from the disposal site. During the disposal radiation measurements were carried out remotely by installing radiations monitors at a distance of 10 m, 25 m, and 50 m from the Tile hole. Estimations of radiation levels were carried out before jobs were taken up. Disposal of 70 numbers of Cobalt SPNDs was carried out by implementing ALARA. The decrease in collective dose is achieved due to improved operational practices, mock-up trials, effective monitoring program and safety compliance at various stages of operation

    The last Construction Permit to be issued by the U.S. Nuclear Regulatory Commission (NRC) for a U.S. light water reactor (LWR) was granted in the late 1970s. In 1989 the NRC issued 10 CFR Part 52 which is intended to serve as a framework for the licensing of future reactor designs. The NRC is currently reviewing four different future on {open_quotes}next-generation{close_quotes} reactor designs. Two of these designs are classified as evolutionary designs (modified versions of current generation LWRs) and two are advanced designs (reactors incorporating simplified designs and passive means for accident mitigation). These {open_quotes}next-generation{close_quotes} reactor designs incorporate many innovative design features which are intended to maintain personnel doses ALARA and ensure that the annual average collective dose at these reactors does not exceed 100 person-rems (1 person-sievert) per year. This paper discusses some of the ALARA design features which are incorporated in the four {open_quotes}next-generation{close_quotes} reactor designs incorporate many innovative design features which are intended to maintain personnel doses ALARA and ensure that the annual average collective dose at these reactors does not exceed 100 person-rems (1 person-sievert) per year.

    Future generation of electrical power using controlled thermonuclear reactors will involve both traditional and new concerns for health protection. A review of the problems associated with exposures to tritium and magnetic fields is presented with emphasis on the occupational worker. The radiological aspects of tritium, inventories and loss rates of tritium for fusion reactors, and protection of the occupational worker are discussed. Magnetic fields in which workers may be exposed routinely and possible biological effects are also discussed

    Developmental models link sexual well-being to physical, mental/emotional, and social well-being, yet little empirical literature evaluates these relationships in adolescents. Better understanding of how and when sexuality complements other aspects of health may yield important points to enhance existing health education and prevention efforts. Data were drawn from a 10-year longitudinal cohort study of sexual relationships and sexual behavior among adolescent women (N = 387; 14-17 years at enrollment). Sexual health data were drawn from quarterly partner-specific interviews and were linked to physical, mental/emotional, and social health information in annual questionnaires. Random intercept, mixed effects linear, ordinal logistic, or binary logistic regression were used to estimate the influence of sexual health on health and well-being outcomes (Stata, v.23, StataCorp, College Station, TX). All models controlled for participant age and race/ethnicity. Higher sexual health was significantly associated with less frequent nicotine and substance use, lower self-reported depression, lower thrill seeking, higher self-esteem, having fewer friends who use substances, higher religiosity, better social integration, lower frequency of delinquent behavior and crime, and more frequent community group membership. Sexual health was not associated with the number of friends who used cigarettes. Positive sexually related experiences in romantic relationships during adolescence may complement physical, mental/emotional, and social health. Addressing specific aspects of healthy sexual development during clinical encounters could dually help primary prevention and health education address other common adolescent health issues.

  7. Multidimensional aspects related to shiftworkers' health and well-being

    Directory of Open Access Journals (Sweden)

    2004-12-01

    Full Text Available The impact of shift and night work on health shows a high inter- and intra-individual variability, both in terms of kind of troubles and temporal occurrence, related to various intervening factors dealing with individual characteristics, lifestyles, work demands, company organisation, family relations and social conditions. The way we define "health" and "well-being" can significantly influence appraisals, outcomes and interventions. As the goal is the optimisation of shiftworkers' health, it is necessary to go beyond the health protection and to act for health promotion. In this perspective, not only people related to medical sciences, but many other actors (ergonomists, psychologists, sociologists, educators, legislators, as well as shiftworkers themselves. Many models have been proposed aimed at describing the intervening variables mediating and/or moderating the effects; they try to define the interactions and the pathways connecting risk factors and outcomes through several human dimensions, which refer to physiology, psychology, pathology, sociology, ergonomics, economics, politics, and ethics. So, different criteria can be used to evaluate shiftworkers' health and well-being, starting from biological rhythms and ending in severe health disorders, passing through psychological strain, job dissatisfaction, family perturbation and social dis-adaptation, both in the short- and long-term. Consequently, it appears rather arbitrary to focus the problem of shiftworkers' health and tolerance only on specific aspects (e.g. individual characteristics, but a systemic approach appears more appropriate, able to match as many variables as possible, and aimed at defining which factors are the most relevant for those specific work and social conditions. This can support a more effective and profitable (for individuals, companies, and society adoption of preventive and compensative measures, that must refer more to "countervalues" rather than to

    2012-09-01

    Full Text Available The main aspects of the control system of training in sport and identified two methodological concepts determine the amount of physical activity during the training sessions. It is established that the physical training and sports activities in the course of employment estimate the value of physical activity mainly due to the reaction rates of the functional systems of the body to an external stimulus. Such an assessment, especially in a narrow range of controllable parameters (for the reaction of the cardiovascular and respiratory systems, is more theoretical in nature and does not allow to clearly define the critical load levels for a particular organism. This problem highlights the need to use a single, integrated, suitable for precise mathematical analysis of the universal, possibly conditional, indicator or criteria for evaluating physical activity. Development of this criterion will optimize the training process at different stages of training opportunities tailored to individual athletes.

    A worker is considered to be hazardous to others when, in the course of performing a specific work task, his/her health problems (e.g., substance dependence, emotional disorders, physical disability, transmissible diseases) pose a risk for other workers' or the public's health and safety, or begins to interfere with ability to function in profession life. The presence of certain illnesses or the fact that a health care worker is impaired because of them do not necessarily imply that he, or she, is hazardous for others. Working in health care increases the probability that an impaired worker being hazardous for others. Management of hazardous workers requires new techniques and procedures, and specific policies. An interdisciplinary group of experts from medical, bioethical, legal and administrative disciplines, together with trade union and employers' representatives, is currently attempting to define a way to put prevention measures into practice in accordance with state laws and individual rights. A consensus document is presented, covering critical aspects such as: social responsibility of the employer, risk management, informed consent, non compliance, confidentiality, responsibility of workers, disclosure of risk to patients, non-discrimination, counselling and recovery of impaired workers, effectiveness of international guidelines. Occupational health professionals are obliged to adhere to ethical principles in the management of "hazardous" workers; the assessment of ethical costs and benefits for the stakeholders is the basis for appropriate decisions.

    Goals of this study were to examine the mental health processes whereby everyday discrimination is associated with physical health outcomes. Data are drawn from a community health survey conducted with 1299 US adults in a low-resource urban area. Frequency of everyday discrimination was associated with overall self-rated health, use of the emergency department, and one or more chronic diseases via stress and depressive symptoms operating in serial mediation. Associations were consistent across members of different racial/ethnic groups and were observed even after controlling for indicators of stressors associated with structural discrimination, including perceived neighborhood unsafety, food insecurity, and financial stress. © The Author(s) 2015.

    2013-01-01

    Full Text Available The paper deals with one of the priority tasks of Russian educational system – developing the health responsibility. The recent health deterioration trend among children and adolescents calls for the complex health care measures, equally affecting the learning outcomes. The authors argue that there is a need for proper definition and specification of the key term of health care quality. However, the analysis of the available scientific and documentary recourses demonstrates the absence of such unified definition. The authors describe the existing approaches to defining the health care quality, and examine structural components of the health care activity, their interrelations and interdependence. In authors’ opinion, the synthesis of the available research materials provides the basis for further studies in the theory and practice of quality management activities regarding the health protection of children, adolescents and young adults in educational institutions.

    Full Text Available Several studies have indicated that motivational level and prior expectations are relevant aspects to increase commitment to physical activity. Moreover, these aspects are not properly described in terms of proximal (Self Determination Theory and distal (evolutionary explanations in the literature. This paper aims to verify if level of motivation (BREQ-2 and expectations regarding regular physical exercise (IMPRAF-54 before starting a one-year exercise program could determine likelihood of completion. Ninety-four volunteers (53 women included a completed protocol group (CPG n=21 and drop-out group (DG n=73. The IMPRAF-54 scale was used to assess six different expectations associated with physical activity, and the BREQ-2 inventory was used to assess the level of motivation in five steps (from amotivation to intrinsic motivation. Both questionnaires were assessed before the regular exercise program. The CPG group presented higher sociability and lower pleasure scores according to IMPRAF-54 domains. A logistic regression showed that a one-point increment on sociability score increased the chance of completing the program by 10%, and the same one-point increment on pleasure score reduced the chance of completing the protocol by 16%. ROC curves were also calculated to establish IMPRAF-54 cutoffs for adherence (Sociability - 18.5 points – 81% sensibility/50% specificity and dropout (Pleasure – 25.5 points – 86% sensibility/20% specificity of the exercise protocol. Our results indicate that an expectation of social interaction was a positive factor in predicting adherence to exercise. Grounded in SDT and its innate needs (competence, autonomy, relatedness, physical exercise is not an end; it is a means to achieve autonomy and self-cohesion. The association of physical activity with social practices, like in hunter-gathering groups, can engage people to be physically active and can provide better results in adherence exercise programs for the

Why practitioners of recreational physical activities do not make systematic use of a particular sports facility ?, Why some sports facility remains almost always empty? Why it is continued unnecessarily reversed large sums of material resources for maintenance? For the simple reason that sports facilities were from the beginning that were not well conceived and designed architecturally, where among other things, not sporting habits and population size of the place properly examined. Similarly, we have witnessed criteria issued regarding the performance of a specific sports field, far from contributing to the extension and improvement of the practice of recreational physical and sports activities in its various manifestations, its null or poor continuous maintenance contributing negatively to limit the sporting life and lacerate mental and physical welfare of the inhabitants of the environment.

    At its meeting on April 23, 1965 in Paris the Bureau of IUTAM decided to have a Symposium on the Irreversible Aspects of Continaum Mechanics held in June 1966 in Vienna. In addition, a Symposium on the Transfer of Physical Characteristics in Moving Fluids which, orig­ inally, had been scheduled to take place in Stockholm was rescheduled to be held in Vienna immediately following the Symposium on the Irre­ versible Aspects of Continuum Mechanics. It was felt that the subjects of the two symposia were so closely related that participants should be given an opportunity to attend both. Both decisions were unanimously approved by the members of the General Assembly of IUTAM. Prof. H. PARKUS, Vienna, was appointed Chairman of the Symposium on the Irreversible Aspects, and Prof. L. I.

    Full Text Available Appropriately trained Human Resources for Health (HRH are key inputs into One Health. ‘… more than 50% of all infectious diseases of humans originate from animals and that, of the emerging diseases about 75% could be traced back to animal origin’ (Rweyemamu et al. 2006. A comprehensive understanding of the social determinants of health, through an appropriate training model for HRH, is a key input. This study aimed to explore if human and veterinary medical schools were using such a model or providing time for this model in their curricula. Specific objectives were to: determine the time that human and veterinary medical schools’ curricula provide for subjects or courses related to the social determinants of health; analyse the curricula contents to establish how they relate to the social determinants of health; and explore how a bio-medical model may influence the graduates’ understanding and practice of One Health. A review of human and veterinary graduate-level medical schools’ curricula in East Africa was performed in April 2013 and May 2013. The findings were: in the curricula, SDH contents for knowledge enhancement about One Health are minimal and that teaching is Germ Theory model-driven and partisan. Out of the total training time for physicians and veterinarians, less than 10% was provided for the social determinants of health-related courses. In conclusion, the curricula and training times provided are inadequate for graduates to fully understand the social determinants of health and their role in One Health. Furthermore, the Germ Theory model that has been adopted addresses secondary causes and is inappropriate. There is a need for more in-depth model. This article suggests that a vicious cycle of ill-health model must be taught.

    2017-12-01

    There is a strong link between mental health and physical health, but little is known about the pathways from one to the other. We analyse the direct and indirect effects of past mental health on present physical health and past physical health on present mental health using lifestyle choices and social capital in a mediation framework. We use data on 10,693 individuals aged 50 years and over from six waves (2002-2012) of the English Longitudinal Study of Ageing. Mental health is measured by the Centre for Epidemiological Studies Depression Scale (CES) and physical health by the Activities of Daily Living (ADL). We find significant direct and indirect effects for both forms of health, with indirect effects explaining 10% of the effect of past mental health on physical health and 8% of the effect of past physical health on mental health. Physical activity is the largest contributor to the indirect effects. There are stronger indirect effects for males in mental health (9.9%) and for older age groups in mental health (13.6%) and in physical health (12.6%). Health policies aiming at changing physical and mental health need to consider not only the direct cross-effects but also the indirect cross-effects between mental health and physical health.

  5. [The importance of physical activity and fitness for human health].

    Science.gov (United States)

    Brandes, M

    2012-01-01

    The decline of physical activity is considered to play an important role in the deterioration of health predictors, such as overweight, and the associated increase of cardiovascular and all-cause mortality. Therefore, most interventional strategies aim for increasing physical activity. Instead of physical activity, some studies use physical fitness as a key variable. Though physical fitness is influenced by genetic factors, physical fitness has to be developed by physical activity. As recent reports demonstrate the prospective associations between physical fitness and health and mortality, these associations are not reported for physical activity. Due to the fact that physical fitness-in contrast to physical activity-is evaluated with standardized laboratory measurements, it appears advisable to assess physical fitness for prospective health perspectives. Although physical fitness is determined by genetics, physical activity is the primary modifiable determinant for increasing physical fitness and should be aimed for to improve physical fitness in interventional strategies.

    DOE Order 5700.6C, Quality Assurance, stipulates QA requirements for all DOE activities. This order is now codified as 10CFR830.120, Nuclear Safety Management, Quality Assurance Requirements, which is applicable to DOE nuclear facilities. A Quality Assurance Management Plan (QAMP) was developed by the Health Physics Operations Group (ESH-1) at Los Alamos National Laboratory (LANL). The goal of the ESH-1 QAMP is to ensure that operational radiation protection activities meet the criteria outlined in DOE Order 5700.6C, DOE-ER-STD-6001-92 and 10CFR830.120. The ten required elements are QA Program, Personal Training and Qualifications, Quality Improvement, Documents and Records, Work Processes, Design, Procurement, Inspection and Acceptance Testing, Management Assessment and Independent Assessment. The QAMP has been useful for the development of QAMPs at nuclear facilities and has helped ensure uniformity of institutional requirements where Health Physics services are deployed to facilities. To implement a subset of QAMP requirements, a Quality Assurance Self-Evaluation Program (QASE) was established. This program provides a novel self-audit mechanism for the formal identification and correction of non-conforming items related to Operational Health Physics. Additionally, the QASE is a useful management tool for Radiological Control Technician Supervisors and staff and provides a tracking mechanism for ongoing problem areas. Data have been Collected for two calendar years on a number of concerns that fall into four general categories: radiological posting and labeling, instrumentation, monitoring requirements, and radiological documents/records

    2015-03-01

    In the past 3 years, the Health Information Technology for Economic and Clinical Health Act accelerated the adoption of electronic health records (EHRs) with providers and hospitals, who can claim incentive monies related to meaningful use. Despite the increase in adoption of commercial EHRs in pediatric settings, there has been little support for EHR tools and functionalities that promote pediatric quality improvement and patient safety, and children remain at higher risk than adults for medical errors in inpatient environments. Health information technology (HIT) tailored to the needs of pediatric health care providers can improve care by reducing the likelihood of errors through information assurance and minimizing the harm that results from errors. This technical report outlines pediatric-specific concepts, child health needs and their data elements, and required functionalities in inpatient clinical information systems that may be missing in adult-oriented HIT systems with negative consequences for pediatric inpatient care. It is imperative that inpatient (and outpatient) HIT systems be adapted to improve their ability to properly support safe health care delivery for children.

The second goal is to examine the aspects of congregational life that is associated with a benevolent image of God. Data from a new nationwide survey (N = 1774) are used to test the following core hypotheses: (1) people who attend worship services more often and individuals who receive more spiritual support from fellow church members (i.e., informal assistance that is intended to increase the religious beliefs and behaviors of the recipient) will have more benevolent images of God, (2) individuals who believe that God is benevolent will feel more grateful to God, (3) study participants who are more grateful to God will be more hopeful about the future, and (4) greater hope will be associated with better health. The data provide support for each of these relationships.

    Women with fibromyalgia (FM) describe great difficulties in managing work. Reported work ability in women with FM varies from 34 to 77 percent in studies from different countries. Many factors are suggested to affect the ability to work in women with FM, including pain, fatigue, impaired physical capacity and activity limitations. However, it is difficult to define to which extent symptom severity can be compatible with work. The aim of this study was to investigate which aspects of health differ between working women with FM and nonworking women with FM. A cross-sectional study of 129 women of working age with FM which included clinical assessment, structured interviews, questionnaires and performance-based tests. The women were categorized as working or nonworking. Aspects of health are presented according to the International Classification of Functioning, Disability and Health (ICF).

    System Health Management functionality is an essential part of any space launch system. Health management functionality is an integral part of mission reliability, since it is needed to verify the reliability before the mission starts. Health Management is also a key factor in life cycle cost reduction and in increasing system availability. The degree of coverage needed by the system and the degree of coverage made available at a reasonable cost are critical parameters of a successful design. These problems are not unique to the launch vehicle world. In particular, the Intelligent Vehicle Highway System, commercial aircraft systems, train systems, and many types of industrial production facilities require various degrees of system health management. In all of these applications, too, the designers must balance the benefits and costs of health management in order to optimize costs. The importance of an integrated system is emphasized. That is, we present the case for considering health management as an integral part of system design, rather than functionality to be added on at the end of the design process. The importance of maintaining the system viewpoint is discussed in making hardware and software tradeoffs and in arriving at design decisions. We describe an approach to determine the parameters to be monitored in any system health management application. This approach is based on Design of Experiments (DOE), prototyping, failure modes and effects analyses, cost modeling and discrete event simulation. The various computer-based tools that facilitate the approach are discussed. The approach described originally was used to develop a fault tolerant avionics architecture for launch vehicles that incorporated health management as an integral part of the system. Finally, we discuss generalizing the technique to apply it to other domains. Several illustrations are presented.

    Basic studies on the process of isotope separation by laser-induced selective ionization have started about fifteen years ago. In the present time, the interest in this process is considerably increased since some countries' decision of funding a substantial R and D program with the ultimate goal of a possible industrial production of reactor grade uranium in the late nineties'. Several hundreds of professionals in the world are now exploring the science of the process, the components technology and the optimal way of industrialization. This review paper is restricted to the physical aspects of the process as they can be understood from the published literature. 55 refs

    Populations affected by armed conflict have experienced severe public health consequences mediated by population displacement, food scarcity, and the collapse of basic health services, giving rise to the term complex humanitarian emergencies. These public health effects have been most severe in underdeveloped countries in Africa, Asia, and Latin America. Refugees and internally displaced persons have experienced high mortality rates during the period immediately following their migration. In Africa, crude mortality rates have been as high as 80 times baseline rates. The most common causes of death have been diarrheal diseases, measles, acute respiratory infections, and malaria. High prevalences of acute malnutrition have contributed to high case fatality rates. In conflict-affected European countries, such as the former Yugoslavia, Georgia, Azerbaijan, and Chechnya, war-related injuries have been the most common cause of death among civilian populations; however, increased incidence of communicable diseases, neonatal health problems, and nutritional deficiencies (especially among the elderly) have been documented. The most effective measures to prevent mortality and morbidity in complex emergencies include protection from violence; the provision of adequate food rations, clean water and sanitation; diarrheal disease control; measles immunization; maternal and child health care, including the case management of common endemic communicable diseases; and selective feeding programs, when indicated.

    Increasingly, Information and Communication Technology (ICT) applications enter the daily lives of consumers. Availability of various multimedia interfaces offers the opportunity to develop and adjust ICT solutions to all aspects of society including health care. To address the challenges of the ongoing adaptive progress of ICT, decision makers profit from estimates of expectable merits and risks of future technological developments. The aim of the present study was to assess the prevailing opinions and expectations among Austrian stakeholders regarding ICT-assisted health promotion. In total, 73 experts (74% males) engaged in the Austrian health care sector participated in a biphasic online Delphi survey. Panellists were assigned to three groups representing medical professionals, patient advocates, and administrative personnel. In a scenario-based questionnaire, experts evaluated potential advantages and barriers as well as degree of innovation, desirability, and estimated date of implementation of six future ICT scenarios. Scenario-specific and consolidated overall opinions were ranked. Inter-group differences were assessed using ANOVA. Panellists expected the future ICT-supported health promotion strategies to especially improve the factors living standard (56%), quality of health care (53%), and patient's knowledge (44%). Nevertheless, monetary aspects (57%), acceptance by patient advocates (45%), and data security and privacy (27%) were considered as the three most substantial hampering factors for ICT applications. Although overall mean desirability of the scenarios was quite high (80%) amongst panellists, it was considerably lower in medical professionals compared to patient advocates and administrative personnel (p=0.006). This observation suggests a more precautious attitude of this specific interest group regarding technological innovations. The present Delphi survey identified issues relevant for successful implementation of ICT-based health care

    Full Text Available Low maternal vitamin D levels during pregnancy have been linked to various health outcomes in the offspring, ranging from periconceptional effects to diseases of adult onset. Maternal and infant cord 25(OHD levels are highly correlated. Here, we review the available evidence for these adverse health effects. Most of the evidence has arisen from observational epidemiological studies, but randomized controlled trials are now underway. The evidence to date supports that women should be monitored and treated for vitamin D deficiency during pregnancy but optimal and upper limit serum 25(OHD levels during pregnancy are not known.

    People diagnosed with serious mental illness have higher rates of physical morbidity and decreased longevity, yet these people are not adequately served by health care systems. Nurses may provide improved physical health support to consumers with serious mental illness but this is partly dependent on nurses having necessary skills and interest in training opportunities for this component of their work. This survey investigated Australian nurses' interest in training across areas of physical health care including lifestyle factors, cardiovascular disease, and identifying health risks. A nation-wide online survey of nurse members of the Australian College of Mental Health Nurses. The survey included an adapted version of a sub-section of the Physical Health Attitudes Scale. Participants were asked to indicate their interest in various aspects of physical health care training. Most (91.6%) participants viewed educating nurses in physical health care as of moderate or significant value in improving the physical health of people with serious mental illness. Interest in training in all areas of physical health care was over 60% across the health care settings investigated (e.g. public, private, primary care). Forty-two percent sought training in all nine areas of physical health care, from supporting people with diabetes, to assisting consumers with sexually-related and lifestyle issues. The findings suggest that nurses in mental health services in Australia acknowledge the importance of training to improve physical health care of consumers with serious mental illness. Training programs and learning opportunities for nurses are necessary to reduce inequalities in health of people with serious mental illness. Copyright © 2013. Published by Elsevier Ltd.

    Background and aims A considerable body of literature has emerged over the past two decades assessing the relationship between problematic or addictive use of the Internet and various indices of psychological well-being. Conversely, comparatively little research has assessed the relationship between problematic or addictive use of the Internet and one's physical health. Method The current study assesses this relationship using a sample of college students (N = 133) who responded online to two questionnaires: the Problematic Internet Use Questionnaire (PIUQ; Demetrovics, Szeredi&Rózsa, 2008) and the SF-36v2 Health Survey (Ware et al., 2008). Results The findings indicate that problematic Internet use is associated with poorer physical health. These results are consistent with other data that assessed the relationship between these two variables. Furthermore, this relationship supersedes the influence of the number of hours spent online per day. Conclusions The findings are discussed in terms of the limitations of the study design and conclusions that can be drawn from this preliminary empirical effort.

    To determine whether demographic factors and coping strategies are related to quality of life in heart transplant candidates. Participants were 50 inpatients being evaluated for heart transplant. Coping was measured using the COPE Inventory (1) (J Pers Soc Psychol, 56, 1989, 267). Quality of life was assessed using the SF-36 (2) (Health Survey: Manual and Interpretation Guide, Quality Metric Inc, Lincoln, RI, 2000). Higher education and less seeking of social support were independently associated with better physical functioning. Higher use of denial was associated with poorer mental health functioning. In patients with significant physical limitations, years of education appears to be protective. Less seeking of social support was associated with better physical functioning perhaps because individuals who feel better physically do not feel the need to elicit support. Alternatively, the tendency to not seek assistance could stem from personality characteristics such as avoidance or optimism. Denial was associated with worse mental health functioning. Denying the existence of a stressor may be a high risk coping strategy for patients who are pre-transplant and even more dangerous for those who are post-transplant given the need to be alert to symptoms. Proactive identification of patients at risk for poorer quality of life will allow for more timely psychosocial interventions, which could impact post-transplant outcomes.

    In consistency with the increasing requests from Member States for establishing radiotherapy programmes, an IAEA Technical Co-operation project was initiated in Latin America aimed at improving the physical aspects (as a complement to the clinical issues) of quality assurance in radiotherapy; this ARCAL XXX project (RLA/6/032) was classified as a Model Project of the IAEA. Among the important outcomes of the project were (i) the training of a considerable number of medical physicists in hospitals of the region, (ii) the development of a protocol for quality control procedures, and (iii) the organization of quality audit site visits (to the participant countries) where the implementation in hospitals of the developed quality control procedures is verified. The present publication is the protocol for quality control of the physical aspects of radiotherapy. It contains detailed procedures on what should be measured by a medical physicist in a radiotherapy treatment unit and related equipment, and how this should be made. The latter is made through several appendices, which make the document rather unique. The protocol was developed by medical physicists of the region for the professionals of the region, and it is the first document of this kind ever written in Spanish. A training course was organized in November 1998 (Havana, Cuba) where its practical implementation was taught. There are plans to have this document translated into different languages for the various regions having similar TC projects. (author)

    Several studies have indicated that motivational level and prior expectations influence one’s commitment to physical activity. Moreover, these aspects are not properly described in terms of proximal (SDT, Self Determination Theory) and distal (evolutionary) explanations in the literature. This paper aims to verify if level of motivation (BREQ-2, Behavioral Regulation in Exercise Questionnaire-2) and expectations regarding regular physical exercise (IMPRAF-54) before starting a 1-year exercise program could determine likelihood of completion. Ninety-four volunteers (53 women) included a completed protocol group (CPG; n = 21) and drop-out group (n = 73). The IMPRAF-54 scale was used to assess six different expectations associated with physical activity, and the BREQ-2 inventory was used to assess the level of motivation in five steps (from amotivation to intrinsic motivation). Both questionnaires were assessed before starting a regular exercise program. The CPG group presented higher sociability and lower pleasure scores according to IMPRAF-54 domains. A logistic regression analysis showed that a one-point increment on sociability score increased the chance of completing the program by 10%, and the same one-point increment on pleasure score reduced the chance of completing the protocol by 16%. ROC curves were also calculated to establish IMPRAF-54 cutoffs for adherence (Sociability – 18.5 points – 81% sensibility/50% specificity) and dropout (Pleasure – 25.5 points – 86% sensibility/20% specificity) of the exercise protocol. Our results indicate that an expectation of social interaction was a positive factor in predicting adherence to exercise. Grounded in SDT and its innate needs (competence, autonomy, relatedness), physical exercise is not an end; it is a means to achieve autonomy and self-cohesion. The association of physical activity with social practices, as occurs in hunter-gathering groups, can engage people to be physically active and can provide

    The nuclear insurance pools, through American Nuclear Insurers (ANI) and the Mutual Atomic Energy Liability Underwriters (MAELU), have been providing the third-party liability insurance required of the nuclear industry by the Price-Anderson Act since 1957. Records of claims of radiation injury have been kept for twenty-five years, and a recent upsurge of the claim rate has been noted. An explanation for this new trend is postulated and some examples are discussed. The use of health physics records as evidence in litigation is described, and specific examples of the types of records required to defend against past and future claims are given

    Full Text Available The aim of this study was to analyze the discourse of health managers on aspects related to delay in tuberculosis diagnosis. This was a qualitative research study, conducted with 16 Family Health Unit managers. The empirical data were obtained through semi-structured interviews. The analysis was based on the theoretical framework of the French school of discourse analysis. According to the managers’ statements, the delay in tuberculosis diagnosis is related to patient and health service aspects. As for patient aspects, managers report fear, prejudice and lack of information as factors that may promote a delayed diagnosis. Regarding health service aspects, structural problems and lack of professional skills were reported. The discourse of managers should be considered to qualify tuberculosis control actions and to prevent delays in diagnosis.

    Meat is an integral part of the human diet. Besides essential amino acids and nutritive factors of high quality and availability, meat provides often overlooked components of importance for human health. These are amino acids and bioactive compounds that may be very important in i) preventing muscle wasting diseases, such as in sarcopenia, ii) reducing food and caloric intake to prevent metabolic syndrome, iii) blood pressure homeostasis via ACE-inhibitory components from connective tissue, and iv) maintaining functional gut environment through meat-derived nucleotides and nucleosides. In addition, meat could be an important source of phytanic acid, conjugated linoleic acids and antioxidants. Further, it becomes increasingly apparent that design of in vitro meat will be possible, and that this development may lead to improved health benefits from commercially viable and sustainable meat products.

    Full Text Available Spirulina, now named Arthrospira, is a microscopic and filamentous cyanobacterium that has a long history of use as a safe food lacking toxicity. It is commercially produced in large outdoor ponds under controlled conditions. The aim of this review article is to summarize available recent information concerning human clinical potential and applications of Spirulina, as well as clinical data related to the safety and side effects of Spirulina. Potential health benefits of Spirulina are mainly due to its chemical composition, which includes proteins (the highest protein content of any natural food, 55%-70%, carbohydrates, essential amino acids, minerals (especially iron, essential fatty acids, vitamins, and pigments. In this respect, three major bioactive components of Spirulina, the protein phycocyanin (a biliprotein pigment, sulfated polysaccharides and gamma linolenic acid seem to play significant role in imparting improved human body functions. Furthermore, new experimental evidence supports the immunomodulation and antiviral effects of Spirulina supplementation. According to the Dietary Supplements Information Expert Committee of United States Pharmacopeial Convention the available clinical evidence does not indicate a serious risk to health or other public health concerns for Spirulina. However, a few cases of severe side-effects have been reported.

    A detailed analysis of data on current employment and projected need indicates that there is a serious impending shortage of qualified professional health physicists within the U.S. Because of the withdrawal and curtailment of Federal financial support, health physics programs at the Master of Science degree levels at many of the nation's colleges and universities are on the decline. Estimates are that during the next 5 to 10 yr, the number of graduates from these programs will be sufficient to meet only about half the projected requirements. Through the Energy Reorganization Act of 1974, a major responsibility for addressing this problem at the Federal level has been assigned to the U.S. Energy Research and Development Administration.

  19. Human radiation experimentation: a health physics perspective

    International Nuclear Information System (INIS)

    Kathren, R.L.

    1996-01-01

    This paper observes ethical human experimentation can be considered in terms of two basic principles or tests: informed, willing and knowledgeable subjects; and expectation of benefits. A number of human experiments are evaluated in terms of these principles, including a sixteenth century toxicology experiment, the deliberate exposure by an x-ray pioneer, and the plutonium injection cases of the 1940's. The following rational ethic is proposed for the practice of health physics with respect to human radiation experimentation: At all levels, the health physicist has a professional as well as personal obligation to ensure that proper human requirements, including proper informed consent and willing subjects, arc carried out with respect to human radiation experimentation, and must be convinced that the real or potential benefits to be derived from the experiment clearly exceed the potential detriment and risk.

    Due to new, previously unknown, properties attributed to engineered nanoparticles many new products are introduced in the agro-food area. Nanotechnologies cover many aspects, such as disease treatment, food security, new materials for pathogen detection, packaging materials and delivery systems. As with most new and evolving technologies, potential benefits are emphasized, while little is known on safety of the application of nanotechnologies in the agro-food sector. This review gives an overview of scientific issues that need to be addressed with priority in order to improve the risk assessment for nanoparticles in food. The following research topics are considered to contribute pivotally to risk assessment of nanotechnologies and nanoparticles in food products. Set a definition for NPs to facilitate regulatory discussions, prioritization of research and exchange of study results. Develop analytical tools for the characterization of nanoparticles in complex biological matrices like food. Establish relevant dose metrics for nanoparticles used for both interpretation of scientific studies as well as regulatory frameworks. Search for deviant behavior (kinetics) and novel effects (toxicity) of nanoparticles and assess the validity of currently used test systems following oral exposure. Estimate the consumer exposure to nanoparticles.

    Among the bacteria, viruses and parasites which may be found in waste-water and polluted waters, those that are pathogenic to man are briefly described. The efficiency of different conventional waste-water treatments in removing the pathogens is reviewed, as well as additional factors of importance for the presence of micro-organisms in recipient waters. It is concluded that at present for treated waters no conventional treatment results in an effluent free from pathogens if they are present in the original waste-water. This is also true for sludges apart from pasteurization. The importance to public health of the presence of pathogens in recipient waters is briefly discussed. (author)

    2016-06-01

    Few studies have examined the health-related consequences of gardening among older adults. This scoping review summarizes and characterizes current research that examines the relationship between physical health and participation in planned gardening activities, including establishing, maintaining, or caring for plants. Six databases were searched. Eligible studies were published between 2000 and 2013, were published in English, and assessed different aspects of physical health (e.g., functional ability, energy expenditure, injury) for older adults who had participated in a planned gardening activity. Of the eight eligible studies identified with these criteria, four assessed energy expenditures and four assessed physical functioning. Studies assessing energy expenditures documented that the majority of gardening tasks were classified into low-to-moderate intensity physical activity. The current literature does not provide sufficient evidence of the physical functioning consequences of gardening. Future studies should consider how specific gardening interventions help older adults meet physical activity guidelines. © The Author(s) 2014.

Vilentas in the 16th–17th cc. K. Sirvydas’ trilingual (Polish-Latin-Lithuanian dictionary “Dictionarium trium linguarum”, the first edition of which appeared in1620, had a great influence on the development of standard language lexis. However, the terminology of physics began to develop much later. Its evolution can be divided in three stages:1 the middle of the 19th c – the end of the 19th c, when the first articles, published in Keleivis (1849–1880 and Aušra (1883–1886, and the first Lithuanian physics textbook of P.

    1975-01-01

    The intensive use of inanimate energy in industrialized or high-energy society has subsidized research, development, and higher education and has brought about changes in nutrition and life-style that have led to great advances in public health and medicine. The emergence of high-energy society, however, has brought with it a new set of health problems, within which the direct effects of measurable pollution may turn out to be more easily dealt with than some of the indirect and hard-to-calculate consequences of high energy use. High-energy society is critically dependent on energy-intensive transport systems, and these systems in turn are dependent upon a continual supply of petroleum products. In the short-term, the aorta of any industrialized nation is its petroleum-supply network. In the longer run, high-energy society faces the depletion and exhaustion of all the nonrenewable resources on which it has fed. Even if technology provides adequate substitute energy systems, high-energy society may deteriorate socially from inability to cope with affluence

  16. Physical aspects of pseudo-Hermitian and PT-symmetric quantum mechanics

    International Nuclear Information System (INIS)

    Mostafazadeh, Ali; Batal, Ahmet

    2004-01-01

    For a non-Hermitian Hamiltonian H possessing a real spectrum, we introduce a canonical orthonormal basis in which a previously introduced unitary mapping of H to a Hermitian Hamiltonian h takes a simple form. We use this basis to construct the observables O α of the quantum mechanics based on H. In particular, we introduce pseudo-Hermitian position and momentum operators and a pseudo-Hermitian quantization scheme that relates the latter to the ordinary classical position and momentum observables. These allow us to address the problem of determining the conserved probability density and the underlying classical system for pseudo-Hermitian and in particular PT-symmetric quantum systems. As a concrete example we construct the Hermitian Hamiltonian h, the physical observables O α , the localized states and the conserved probability density for the non-Hermitian PT-symmetric square well. We achieve this by employing an appropriate perturbation scheme. For this system, we conduct a comprehensive study of both the kinematical and dynamical effects of the non-Hermiticity of the Hamiltonian on various physical quantities. In particular, we show that these effects are quantum mechanical in nature and diminish in the classical limit. Our results provide an objective assessment of the physical aspects of PT-symmetric quantum mechanics and clarify its relationship with both conventional quantum mechanics and classical mechanics

    Preventive mental health measures can be properly planned only if the various factors leading to the adolescent's personality structure are extensively investigated. Starting with the specific attitudes of a couple towards genetic counselling, the disadvantages of urbanization and of the dissolution of the traditional extended family are discussed with regard to their effect on the younger members. Data are produced concerning the child-rearing practices of Greek in comparison to American parents and their effect on the adolescent's emotional life. Extreme dependence on the family, pressure for school achievements, lack of sexual education, etc. are characteristic of the stresses a Greek adolescent undergoes. Socio-cultural conditions, like immigration, adoption, etc. are shown to have a different psychological effect on an adolescent in Greece than in America. Specific stresses regarding the adolescent's future, like preparing for university entrance examinations, are discussed and preventive measures are proposed.

    Diverse microorganisms are able to grow on food matrixes and along food industry infrastructures. This growth may give rise to biofilms. This review summarizes, on the one hand, the current knowledge regarding the main bacterial species responsible for initial colonization, maturation and dispersal of food industry biofilms, as well as their associated health issues in dairy products, ready-to-eat foods and other food matrixes. These human pathogens include Bacillus cereus (which secretes toxins that can cause diarrhea and vomiting symptoms), Escherichia coli (which may include enterotoxigenic and even enterohemorrhagic strains), Listeria monocytogenes (a ubiquitous species in soil and water that can lead to abortion in pregnant women and other serious complications in children and the elderly), Salmonella enterica (which, when contaminating a food pipeline biofilm, may induce massive outbreaks and even death in children and elderly), and Staphylococcus aureus (known for its numerous enteric toxins). On the other hand, this review describes the currently available biofilm prevention and disruption methods in food factories, including steel surface modifications (such as nanoparticles with different metal oxides, nanocomposites, antimicrobial polymers, hydrogels or liposomes), cell-signaling inhibition strategies (such as lactic and citric acids), chemical treatments (such as ozone, quaternary ammonium compounds, NaOCl and other sanitizers), enzymatic disruption strategies (such as cellulases, proteases, glycosidases and DNAses), non-thermal plasma treatments, the use of bacteriophages (such as P100), bacteriocins (such us nisin), biosurfactants (such as lichenysin or surfactin) and plant essential oils (such as citral- or carvacrol-containing oils).

    Sugarcane (Saccharum officinarum Linn.) is an important perennial grass of Poaceae family, indigenous to tropical South Asia and Southeast Asia. It is cultivated worldwide due to the economical and medicinal value of its high yielding products. Sugarcane juice is well known as a raw material for the production of refined sugar and its wax is considered as a potential substitute for the expensive carnauba wax, which is of cosmetic and pharmaceutical interest. Refined sugar is the primary product of sugarcane juice, but during its processing, various other valuable products are also obtained in an unrefined form, such as, brown sugar, molasses, and jaggery. Sugarcane juice is widely used in India in the treatment of jaundice, hemorrhage, dysuria, anuria, and other urinary diseases. Herein, we have summarized the different phytoconstituents and health benefits of sugarcane and its valuable products. The phytochemistry of sugarcane wax (obtained from the leaves and stalks of sugarcane), leaves, juice, and its products has revealed the presence of various fatty acid, alcohol, phytosterols, higher terpenoids, flavonoids, -O- and -C-glycosides, and phenolic acids. The future prospective of some of the sugarcane products has been discussed, which needs a phytopharmacological study and has a great potential to be a valuable medicinal product.

    Veterinary herd health management (VHHM) programmes have been shown to be economically effective in the past. However, no current information is available on costs and benefits of these programmes. This study compared economics and farm performance between participants and non-participants in VHHM programmes in 1013 dairy farms with over 40 cows. Milk Production Registration (MPR) data and a questionnaire concerning VHHM were used. Based on the level of participation in VHHM (as indicated in the questionnaire), costs of the programmes were calculated using a normative model. The economic value of the production effects was similarly calculated using normative modelling based on MPR data. Participants in VHHM had a better performance with regard to production, but not with regard to reproduction. Over 90 per cent of the VHHM participants were visited at least once every six weeks and most participants discussed at least three topics. In most farms, the veterinarian did the pregnancy checks as part of the VHHM programmes. There was a benefit to cost ratio of about five per cow per year for VHHM participants, and a mean difference in net returns of €30 per cow per year after adjusting for the cost of the programme. This portrays that participation in a VHHM programme is cost-efficient. There is, however, much unexplained variation in the net returns, possibly due to diverse approaches by veterinarians towards VHHM or by other factors not included in this analysis, like nutritional quality or management abilities of the farmer.

    The storage of wood fuel chips, in general, leads to the establishment of microbial activity in the pile. Fungi are one of these microorganisms which can grow vigorously in stored forest products. Different types of fungi are commonly present on wood chip pile; rot fungi, blue stain fungi and moulds. Each fungis has its optimum temperature and humidity. Fungi also differ in their ability to utilize different components of the biofuel; moulds are unable to degrade lignin and only few species can degrade cellulose. Rot fungi on the other hand can attack all parts of the substrate and degrade it to varying degrees. Sporulation in fungi is their mechanisms for reproduction and survival. The spores are produced asexually in special spore carriers which are specific for each type of fungi. In stored wood chip pile the sporulation of moulds is the source of health hazard due to its ability to produce very large numbers of microspores in a short period. These microspores are usually airborne and they are almost always present in air but their numbers differ with time, weather and location. Most people can tolerate the presence of these microfungi at concentrations up to 10{sup 6} spore/m{sup 3} air, but a more intense exposure of 10{sup 10} spores/m{sup 3} air con provoke allergic reactions in certain individuals causing allergic alveolitis. The growth of different fungi on stored wood chips pile depends on the time and the system of storage that is used for that pile. In general, indoors storage, high moisture contents and excess of fine fractions are factors that could lead to intensive fungal activity. Handling of such material necessitate the use of protective helmet to avoid the risks of allergic reactions. (4 refs.) (au).

    Full Text Available Phenylketonuria is a rare metabolic disorder that occurs due to the lack of liver enzyme phenylalanine hydroxylase. Untreated it leads to mental retardation, delayed development of speech, microcephaly, epilepsy, behavioral problems etc. Its treatment consists of strict diet, very low in phenylalanine content. The aim of this study was to determine the health safety and suitability of 17 selected foods labeled as „low in protein" respectively „foods low in phenylalanine". Analyses were focused on their phenylalanine content and aminoacid representation. The other aim was to compare phenylalanine measured with the content declared by the producers on their label. By product origin, the largest amount of foodstuffs originated from Poland (59%, followed by Germany (23% and equal representation (6% had Slovakia, Hungary and Sweden. Automatic analyzer AAA 400, using ion exchange chromatography, analyzed the samples. The lowest determined phenylalanine content was 1 mg.100g-1 (in rubber candy and the highest 299 mg.100g-1 (in paté. Powdered egg alternative was monitored as the second highest source of phenylalanine. Phenylalanine content in the monitored foods ranged from 1 to 299.6 mg. 100 g-1 respectively, and increased in the following order: Gum candies (1 mg.100g-1 < Cherry jelly (1.4 mg. 100g-1 < Flour (5.8 mg.100g-1 < Flour (5.9 mg.100g-1 < Spaghetti (8.7 mg.100g-1 < Pasta (9.9 mg.100g-1 < Waffle (14.2 mg.100g-1 < Salty sticks (23.8 mg.100g-1 < Chocolate (24.1 mg.100g-1 < Bread (26 mg.100g-1 < Breadcrumbs (27.1 mg.100g-1 < Sticks with salt (30.3 mg.100g-1 < Ice Cornets (30.8 mg.100g-1 < Walnut cookie (37.2 mg.100g-1 < Instant soup with noodles (46.1 mg.100g-1 < Powdered egg alternative (58 mg.100g-1 < Pate (299.6 mg.100g-1.

    1977-01-01

    In the Federal Republic of Germany knowledge in health physics is imparted mainly as a supplement training in courses of some days up to a few weeks duration. This may be adequate for strictly defined sectors, although it is not sufficient as to the education of a true health physicist. Already in the early sixties the necessity of such special training was recognized at the Karlsruhe Nuclear Research Center and training was started of 'health physics assistants' as this profession is called. Significant details are given about training, the contributions of the individual training institutions (Karlsruhe Nuclear Research Center, nuclear medical hospital, Euratom institute, S.C.P.R.I.) examinations and subjects examined, experience regarding future employments and activities

    1985-08-01

    An assessment is made of the biological effects and physical hazards of static and time-varying fields associated with the NMR devices that are being used for clinical imaging and in vivo spectroscopy. A summary is given of the current state of knowledge concerning the mechanisms of interaction and the bioeffects of these fields. Additional topics that are discussed include: (1) physical effects on pacemakers and metallic implants such as aneurysm clips, (2) human health studies related to the effects of exposure to nonionizing electromagnetic radiation, and (3) extant guidelines for limiting exposure of patients and medical personnel to the fields produced by NMR devices. On the basis of information available at the present time, it is concluded that the fields associated with the current generation of NMR devices do not pose a significant health risk in themselves. However, rigorous guidelines must be followed to avoid the physical interaction of these fields with metallic implants and medical electronic devices. 476 refs., 5 figs., 2 tabs.

    Health physics education and training (HPET) are close counterparts for an effective enforcement of radiation protection (RP) regulations and development of an advanced RP infrastructure in a country. The related history in Iran dates back to over 30 years ago advancing towards promotion of a 'Sustainable Training Program' (STP) through programs such as academic courses, intensive courses, research, on-the-job training and media training. The STP has been effective in development of an advanced national infrastructure for effective enforcement of regulations in different applications and provision of self-sustained national services. In this paper, the elements of a long-term national STP are discussed with a hope it could act as a model in developing countries. (author)

  14. Health physics instrumentation - a progress report

    Maushart, R.

    1992-01-01

    Health Physics Instruments have changed rather dramatically in the past decade. On the one hand, technological innovations like Microprocessors, data storage facilities and imaging displays have altered shape, size and appearance of the classical devices, particularly the hand-held ones. On the other hand, instruments are increasingly being considered as an integral part of Radiation Protection procedures and organizations, supporting a smooth and reliable implementation of all necessary measures. This implies ease of operation, and extensive self-checking and performance control features. Since there are different categories of users with quite different degrees of motivation and training, the measuring instruments of the future will have to be adapted to specific types of users. Instruments for 'professional' radiation protection - for example in nuclear power plants and nuclear technology - will differ from instruments used in the radionuclide laboratory, where radiation protection will necessarily have to be done as a 'side-job'.

    1994-02-01

    The Health Physics Positions (HPPOS) Data Base of the Nuclear Regulatory Commission (NRC) is a collection of NRC staff positions on a wide range of topics involving radiation protection (health physics). It consists of 328 documents in the form of letters, memoranda, and excerpts from technical reports. The HPPOS Data Base was developed by the NRC Headquarters and Regional Offices to help ensure uniformity in inspections, enforcement, and licensing actions. Staff members of the Oak Ridge National Laboratory (ORNL) have assisted the NRC staff in summarizing the documents during the preparation of this NUREG report. These summaries are also being made available as a {open_quotes}stand alone{close_quotes} software package for IBM and IBM-compatible personal computers. The software package for this report is called HPPOS Version 2.0. A variety of indexing schemes were used to increase the usefulness of the NUREG report and its associated software. The software package and the summaries in the report are written in the context of the {open_quotes}new{close_quotes} 10 CFR Part 20 ({section}{section}20.1001--20.2401). The purpose of this NUREG report is to allow interested individuals to familiarize themselves with the contents of the HPPOS Data Base and with the basis of many NRC decisions and regulations. The HPPOS summaries and original documents are intended to serve as a source of information for radiation protection programs at nuclear research and power reactors, nuclear medicine, and other industries that either process or use nuclear materials.

  17. HOTSPOT Health Physics codes for the PC

    Energy Technology Data Exchange (ETDEWEB)

    Homann, S.G.

    1994-03-01

    The HOTSPOT Health Physics codes were created to provide Health Physics personnel with a fast, field-portable calculation tool for evaluating accidents involving radioactive materials. HOTSPOT codes are a first-order approximation of the radiation effects associated with the atmospheric release of radioactive materials. HOTSPOT programs are reasonably accurate for a timely initial assessment. More importantly, HOTSPOT codes produce a consistent output for the same input assumptions and minimize the probability of errors associated with reading a graph incorrectly or scaling a universal nomogram during an emergency. The HOTSPOT codes are designed for short-term (less than 24 hours) release durations. Users requiring radiological release consequences for release scenarios over a longer time period, e.g., annual windrose data, are directed to such long-term models as CAPP88-PC (Parks, 1992). Users requiring more sophisticated modeling capabilities, e.g., complex terrain; multi-location real-time wind field data; etc., are directed to such capabilities as the Department of Energy`s ARAC computer codes (Sullivan, 1993). Four general programs -- Plume, Explosion, Fire, and Resuspension -- calculate a downwind assessment following the release of radioactive material resulting from a continuous or puff release, explosive release, fuel fire, or an area contamination event. Other programs deal with the release of plutonium, uranium, and tritium to expedite an initial assessment of accidents involving nuclear weapons. Additional programs estimate the dose commitment from the inhalation of any one of the radionuclides listed in the database of radionuclides; calibrate a radiation survey instrument for ground-survey measurements; and screen plutonium uptake in the lung (see FIDLER Calibration and LUNG Screening sections).

    People with serious mental illness have increased rates of physical ill-health and reduced contact with primary care services. In Australia, the Mental Health Nurse Incentive Program (MHNIP) was developed to facilitate access to mental health services. However, as a primary care service, the contribution to physical health care is worthy of consideration. Thirty-eight nurses who were part of the MHNIP participated in a national survey of nurses working in mental health about physical health care. The survey invited nurses to report their views on the physical health of consumers and the regularity of physical health care they provide. Physical health-care provision in collaboration with general practitioners (GPs) and other health-care professionals was reported as common. The findings suggest that the MHNIP provides integrated care, where nurses and GPs work in collaboration, allowing enough time to discuss physical health or share physical health activities. Consumers of this service appeared to have good access to physical and mental health services, and nurses had access to primary care professionals to discuss consumers' physical health and develop their clinical skills in the physical domain. The MHNIP has an important role in addressing physical health concerns, in addition to the mental health issues of people accessing this service. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

  2. Confinement physic study in a small low-aspect-ratio helical device CHS

    The configuration parameter of the plasma position relative to the center of the helical coil winding is very effective one for controlling the MHD stability and the trapped particle confinement in Heliotron/Torsatron systems. But these two characteristics are contradictory to each other in this parameter. The inward shifted configuration is favorable for the drift-orbit-optimization but it is predicted unstable with the Mercier criterion. Various physics problems, such as electric field structure, plasma rotation and MHD phenomena, have been studied in CHS with a compromising intermediate position. With this standard configuration, CHS has supplied experimental results for understanding general toroidal confinement physics and low-aspect-ratio helical systems. In the recent experiments, it was found that the wide range of inward shifted configurations gives stable plasma discharges without any restriction to the special pressure profile. Such enhanced range of operation made it possible to study experimentally the drift-orbit-optimized configuration in the Heliotron/Torsatron systems. The effect of configuration improvement was studied with plasmas in a low collisionality regime. (author)

  3. Mutually exclusive aspects of information carried by physical systems: Complementarity between local and nonlocal information

    Complex physical systems contain information which, under some well-defined processes can differentiate between local and nonlocal information. Both these fundamental aspects of information are defined operationally. Local information is locally accessible and allows one to perform processes, such as physical work, while nonlocal information allows one to perform processes such as teleportation. It is shown that these two kinds of information are complementary in the sense that two parties can either gain access to the nonlocal information or to the local information but not both. This complementarity has a form similar to that expressed by entropic uncertainty relations. For pure states, the entanglement plays the role of Planck's constant. We also find another class of complementarity relations which applies to operators and is induced when two parties can only perform local operations and communicate classical (LOCC). In particular, observables such as the parity and phase of two qubits commute but under LOCC, they are complementary observables. It is also found this complementarity is pure in the sense that it can be ''decoupled'' from the uncertainty principle. It is suggested that these complementarities represent an essential extension of Bohr's complementarity to complex (distributed) systems which are entangled

    Full Text Available The working world is a sphere of life that most people at some point in life you willexperience. Thus, it becomes essential to know and explore the views of workersabout their experiences and issues related to welfare and health. This study objective of this study is to identify and analyze the perceptions of workers about the physicaland social environment. Research participants were 12 subjects who became ill on the job and have been removed or needed psychological help from organizations of different segments. After approval of the research project by the Ethics Research was conducted to collect data through a script of semi-structured interview about personal, professional, social worker and perceptions about what the work represents in your life. The responses were analyzed qualitatively and quantitatively. The accounts of the participants indicated the need for relief in relation to work on aspects of work flow and division of tasks with lower load. Other things that annoy workers refer to social relations, especially complaints of leadership posture in which they feel somewhat devalued. This research contributes to the expansion of knowledge about the subject and the need to encourage more investment in the area, to enable greater well-being of workers in general, particularly the bio psychosocial aspects.

    E-health is an emerging field on the intersection of medical information technologies, public health and business, referring to health services and information delivered or enhanced through the Internet and related technologies. Portal technology, allowing services to be accessible over the Internet is a perfect tool for providing e-health services. The use of portal technologies has had deep influence on the architecture of the whole e-health system, both regarding new subsystems and older ones which we want to integrate with the portal. Portals provide new possibilities for creating novel types of e-health applications as well. In this paper we provide a brief overview of e-health systems and portal technologies, and present many technical aspects of portal technology application for e-health systems such as the architecture of portal-based e-health systems, graphical user interfaces, access to various e-health systems' resources, personalization, security and privacy.

    2004-01-01

    The Japan Health Physics Society set an ad hoc working group (hereinafter 'the Working Group') to investigate the proposals presented by Professor Roger Clarke, chairman of the ICRP, 111 1999 towards new ICRP recommendations, and to make suggestions from the standpoint as an academic society for radiological protection in Japan. The Working Group discussed the present situation of the system of radiation protection and the ICRP Proposals with regard to the items oh definition of dose, health effect of radiation, dose and dose level, category of exposure, optimisation and role of stakeholder, collective dose, exclusion and exemption, and medical exposure. The basic policy of the Working Group is that the philosophy and criteria of the system of radiation protection, which are now effectively used for relevant regulations or some other purposes and are functioning well, should be basically retained unless there are positive reasons for revising them on specific; grounds. The ICRP Proposals, an individual-oriented radiation protection concept, should basically be coherent with present protection system, a societal-oriented radiation protection concept, and should have enough rational scientific grounds. The Working Group: (1) suggests there is a need for scientific rationality in any newly introduced criteria or standards for the system of radiation protection; (2) understands, for the present, that there is no other option but to adopt the linear no-threshold (LNT) hypothesis relating dose and risk of health effects at low level radiation exposures. This is the precautionary principle as applied to radiological protection; (3) recommends the role of stakeholders be explained as an example of one of the steps in the optimisation process; (4) suggests protective action level or dose limits should he related to radiation risk, even though these levels indicate only when to begin considering protective actions; and (5) believes that establishing a system of radiation

    2014-12-01

    This study examined the effects of social network characteristics on physical health among people with serious mental illness using social transactions that are reciprocal, and the combination of objective and subjective health measures. The sample consisted of a probability sample of 231 adults with serious mental illness who resided in permanent supportive housing in Philadelphia, Pennsylvania. Path analyses were conducted to examine the relationships between social network characteristics and two aspects of medical comorbidity, objective health and subjective health. Bivariate statistics showed that individuals with medical comorbidity were more likely to have contact with their network members and had a higher level of reciprocal positive tangible support when compared to those who did not have medical comorbidity. The results of the path analyses revealed that none of the social network characteristics were associated with better physical health. The lack of a significant relationship between social networks and better physical health is contrary to prior research findings. However, this is the first study to include both types of social transactions simultaneously as predictors of better physical health for individuals with serious mental illness. A longitudinal study would provide more insight into the temporal relationship of social networks and physical health conditions of people with serious mental illness. Furthermore, the transactional nature of social relationships, particularly for those with mental health issues, requires greater exploration.

    Lakey, S.R.A.; Gibbs, D.C.C.; Marchant, C.P.

    1980-01-01

    The Royal Naval College has devised a number of computer aided learning programmes applicable to health physics which include radiation shield design and optimisation, environmental impact of a reactor accident, exposure levels produced by an inert radioactive gas cloud, and the prediction of radiation detector response in various radiation field conditions. Analogue computers are used on reduced or fast time scales because time dependent phenomenon are not always easily assimilated in real time. The build-up and decay of fission products, the dynamics of intake of radioactive material and reactor accident dynamics can be effectively simulated. It is essential to relate these simulations to real time and the College applies a research reactor and analytical phantom to this end. A special feature of the reactor is a chamber which can be supplied with Argon-41 from reactor exhaust gases to create a realistic gaseous contamination environment. Reactor accident situations are also taught by using role playing sequences carried out in real time in the emergency facilities associated with the research reactor. These facilities are outlined and the training technique illustrated with examples of the calculations and simulations. The training needs of the future are discussed, with emphasis on optimisation and cost-benefit analysis. (H.K.)

  15. RPL dosimetry. Radiophotoluminescence in health physics

    International Nuclear Information System (INIS)

    Perry, J.A.

    1987-01-01

    The luminescence phenomena described in this book are those that are most likely to be of practical use; RPL is particularly suitable for the measurement of absorbed dose resulting from interactions with ionising radiations. The book examines the phenomena of radio-photoluminescence and proceeds to describe particular materials which exhibit the necessary fluorescence, their behaviour, dosimetric properties and the wide range of alternative measurement techniques that may be applied to them in a variety of monitoring environments. The emphasis is primarily on implementation in health physics as a personal and environmental monitor and particular reference is made to the use of RPL as a research tool for radiotherapy treatment planning and in the context of civil defence. The author reviews the design, operation and basic operational principles of some of the readers currently in service or being developed. The logistics of operating small and large monitoring services are considered and there is a useful comparison between glass, thermoluminescence and film methods of dosimetry to enable potential users to evaluate the merits of each from a theoretical and practical point of view.

    Yaffe, M; Hill, M

    2012-06-01

    To describe the current state of dual energy contrast-enhanced digital mammography, to discuss those aspects of its operation that require evaluation or monitoring and to propose elements of a program for quality assurance of such systems. The principles of dual-energy contrast imaging will be discussed and tools and techniques for assessment of performance will be described. Many of the elements affecting image quality and dose performance in digital mammography (eg noise, system linearity, consistency of x-ray output and detector performance, artifacts) remain important. In addition, the ability to register images can influence the resultant image quality. The maintenance of breast compression thickness during the imaging procedure and calibration of the system to allow quantification of iodine in the breast represent new challenges to quality assurance. CESM provides a means of acquiring new information regarding tumor angiogenesis and may reveal some cancers that will not be detectable on digital mammography. It may also better demonstrate the extent of disease. The medical physicist must understand the dependence of image quality on physical factors. Implementation of a relevant QA program will be required if the promise of this new modality is to be delivered. © 2012 American Association of Physicists in Medicine.

  19. Aspects of artificial neural networks - with applications in high energy physics

    Roegnvaldsson, T.S.

    1994-02-01

    Different aspects of artificial neural networks are studied and discussed. They are demonstrated to be powerful general purpose algorithms, applicable to many different problem areas like pattern recognition, function fitting and prediction. Multi-layer perceptron (MPL) models are shown to out perform previous standard approaches on both off-line and on-line analysis tasks in high energy physics, like quark flavour tagging and mass reconstruction, as well as being powerful tools for prediction tasks. It is also demonstrated how a self-organizing network can be employed to extract information from data, for instance to track down origins of unexpected model discrepancies. Furthermore, it is proved that the MPL is more efficient than the learning vector quantization technique on classification problems, by producing smoother discrimination surfaces, and that an MPL network should be trained with a noisy updating schedule if the Hessian is ill-conditioned - A result that is especially important for MPL network with more than just one hidden layer. 81 refs, 6 figs

  20. Effectiveness of the endotracheal tube cuff on the trachea: physical and mechanical aspects

    Directory of Open Access Journals (Sweden)

    Maira Soliani Del Negro

    2014-12-01

    Full Text Available Introduction: The inflation pressure of the endotracheal tube cuff can cause ischemia of the tracheal mucosa at high pressures; thus, it can cause important tracheal morbidity and tracheal microaspiration of the oropharyngeal secretion, or it can even cause pneumonia associated with mechanical ventilation if the pressure of the cuff is insufficient. Objective: In order to investigate the effectiveness of the RUSCH® 7.5 mm endotracheal tube cuff, this study was designed to investigate the physical and mechanical aspects of the cuff in contact with the trachea. Methods: For this end, we developed an in vitro experimental model to assess the flow of dye (methylene blue by the inflated cuff on the wall of the artificial material. We also designed an in vivo study with 12 Large White pigs under endotracheal intubation. We instilled the same dye in the oral cavity of the animals, and we analyzed the presence or not of leakage in the trachea after the region of the cuff after their deaths (animal sacrifice. All cuffs were inflated at the pressure of 30 cmH2O. Results: We observed the passage of fluids through the cuff in all in vitro and in vivo experimental models. Conclusion: We conclude that, as well as several other cuff models in the literature, the RUSCH® 7.5 mm tube cuffs are also not able to completely seal the trachea and thus prevent aspiration of oropharyngeal secretions. Other prevention measures should be taken.

    Breast cancer is the major cause of mortality among female population in Serbia. It is presumed that the introduction of screening programme will reduce mortality and therefore, 47 new mammography units were installed for the purpose of population-based screening program in 2011. In parallel, Quality assurance and Quality control (QC) in mammography has received increasing attention as an essential element of the successful breast cancer campaign that is for the first time initialed in Serbia. The purpose of this study is to investigate the need for and the possible implementation of the comprehensive QC programme for the mammography screening in Serbia, with special focus on physical and technical aspect. In the first phase, a QC protocols containing list of parameters, methodology, frequency of tests and reference values for screen-film, computed radiography and full-filed digital mammography) units, were developed. The second phase is focused on the initial implementation of these protocols. The paper presents results of tests of the selected parameters in 35 mammography units, with special emphasis on patient dose and image quality descriptors. After initial implementation at the beginning of the population based breast cancer screening campaign, it is essential to establish system of regular and periodic QC equipment monitoring and to ensure high quality mammograms with minimal possible radiation dose to population included in the screening.

    2014-01-01

    Low levels of physical activity are a global health concern for all children. Children with cerebral palsy have even lower physical activity levels than their typically developing peers. Low levels of physical activity, and thus an increased risk for related chronic diseases, are associated with deficits in health-related physical fitness. Recent research has provided therapists with the resources to effectively perform physical fitness testing and physical activity training in clinical settings with children who have cerebral palsy, although most testing and training data to date pertains to those who walk. Nevertheless, based on the present evidence, all children with cerebral palsy should engage, to the extent they are able, in aerobic, anaerobic and muscle strengthening activities. Future research is required to determine the best ways to evaluate health-related physical fitness in non-ambulatory children with cerebral palsy and foster long-term changes in physical activity behavior in all children with this condition.

    2014-01-01

    Full Text Available Background. Physical activity is associated with better physical health, possibly by changing biological markers of health such as waist circumference and inflammation, but these relationships are unclear and even less understood among older Latinos—a group with high rates of sedentary lifestyle. Methods. Participants were 120 sedentary older Latino adults from senior centers. Community-partnered research methods were used to recruit participants. Inflammatory (C-reactive protein and metabolic markers of health (waist circumference, HDL-cholesterol, triglycerides, insulin, and glucose, physical activity (Yale physical activity survey, and physical performance (short physical performance NIA battery were measured at baseline and 6-month followup. Results. Eighty percent of the sample was female. In final adjusted cross-sectional models, better physical activity indices were associated with faster gait speed (P<0.05. In adjusted longitudinal analyses, change in self-reported physical activity level correlated inversely with change in CRP (β=-0.05; P=0.03 and change in waist circumference (β=-0.16; P=0.02. Biological markers of health did not mediate the relationship between physical activity and physical performance. Conclusion. In this community-partnered study, higher physical activity was associated with better physical performance in cross-sectional analyses. In longitudinal analysis, increased physical activity was associated with improvements in some metabolic and inflammatory markers of health.

  14. [Psychological benefits of physical activity for optimal mental health].

    Science.gov (United States)

    Poirel, Emmanuel

    Mental health is a worldwide public health concern, as can be seen from the WHO's comprehensive mental health action plan 2013-2020 which was adopted by the 66th World Health Assembly. According to the Mental health commission of Canada (2012), one in five Canadians will personally experience a mental illness in their lifetime, and the WHO shows that mental illness represents the second most prevalent risk of morbidity after heart disease. Physical activity certainly provides an answer to this problem. Physical activity has been shown to improve physical health but it is also one of the most natural and accessible means to improve mental health. The aim of the present article is to propose a biopsychosocial model on the basis of a literature review on the psychological benefits of physical activity. In view of the findings we assume that physical activity increases mental well-being and optimal mental health as opposed to poor mental health. Hence, physical activity provides a state of well-being that enables individuals to realize their own potential, and that helps to cope with the normal stresses of life or adversity. The model certainly opens the way for research and new hypothesis, but it also aims at the promotion of the benefits of physical activity on psychological well-being for optimal mental health.

    Sexual minorities experience higher rates of several physical health problems compared to their heterosexual counterparts. The present study uses Meyer's Minority Stress Model (Psychological Bulletin, 129(5): 674-697, 2003) to examine physical health indicators among 250 adults who identified as sexual minorities. Study hypotheses include that sexual minority stress is predictive of two physical health indicators (i.e., engagement in a health-promoting lifestyle and number of physical health problems) and that planning (i.e., problem-focused) and social support coping will partially mediate the relationship between sexual minority stress and each physical health indicator. Results showed that as level of sexual minority stress increased, engagement in a health-promoting lifestyle decreased and the number of physical health problems increased. Planning and social support coping did not mediate these relationships; however, as levels of coping increased, engagement in a health-promoting lifestyle increased. These findings have implications for researchers and healthcare professionals in their efforts to promote the physical health of sexual minorities.

  16. Healthy hearts--and the universal benefits of being physically active: physical activity and health.

    Although ancient thinkers suggested that physical activity is good for health, systematic research on the topic did not begin until the middle of the 20th century. Early reports showed that individuals in active occupations had lower rates of heart disease than individuals in sedentary occupations. Investigators then began to evaluate leisure-time physical activity and health and found similar results. Later research used objective measures of cardiorespiratory fitness as the exposure, and found even stronger associations with health outcomes. Recent research has extended the earlier findings on activity or fitness and heart disease to a wide variety of health outcomes. We now know that regular physical activity of 150 minutes/week of moderate intensity physical activity reduces the risk of numerous chronic diseases, preserves health and function (both physical and mental) into old age, and extends longevity. The current challenge is to develop programs and interventions to promote physical activity for all in our increasingly sedentary societies.

  17. O Some Aspects of the Relationship Between Quantum Physics, Gravity and Thermodynamics.

    Science.gov (United States)

    Stephens, Christopher Rhodes

    In this dissertation an attempt is made to shed some new light on various aspects of the relation between quantum physics, gravity and thermodynamics. The well known Hawking-Unruh effect is explored and reviewed and some original results found. It is found that the noise spectrum for a massless scalar field along an accelerated trajectory in odd dimensional Minkowski space has a (pseudo) -Fermi-Dirac form contrary to expectations. Ambiguous questions about covariance that have arisen when considering the physics of accelerated observers are addressed critically. It is found that if one is careful about specifying just what "observer" means then no ambiguities can arise. The idea of what constitutes a "particle" is also critically discussed. The uniqueness of the gravitational field vis a vis thermal effects is investigated. It is found that pair production in a uniform electric field admits of a thermal interpretation, (one with some interesting subtleties), thereby showing the non-uniqueness of gravity in this respect. The notion of intrinsic entropy remains a singular feature of gravity however. A corollary of the above is that the Unruh effect is an integral part of a quantum field theory and not some additional baggage. In treating the above questions some very interesting techniques are developed. The PTPI formalism allows a relativistic quantum field calculation to be performed without ever mentioning a quantum field(!) by reformulating such a problem into a quantum mechanical analog. As the problem is now finite dimensional, one loop determinants can be calculated using the method of Jacobi fields, rather than as infinite dimensional functional determinants. In general the methodology allows one to obtain covariances of partial differential equations from the covariances of ordinary differential equations!. The thermal effects discussed herein are seen to be just a small part of a much broader phenomenon--finite size effects. Such effects have been

  5. Different aspects of nuclear physics from low energies up to intermediate energies

    International Nuclear Information System (INIS)

    Lallouet, Y.

    2011-12-01

    This study focuses on different aspects of nuclear physics from low energies to intermediate ones. For the low energies, the nuclear matter is essentially constituted from interacting nucleons. Part I is on the fusion-fission of super-heavy elements, while Part II is on the Skyrme interactions associated sum rules. In the case of the intermediate energies, where the nuclear matter is considered as being an hadronic phase mainly constituted from pions, Part III is focused on nuclear matter relativistic hydrodynamics with spontaneous chiral symmetry breaking. In Part I, the formation and the deexcitation of super-heavy nuclei are being studied. The memory effect must be taken into consideration within the super-heavy nuclei formation dynamics. Therefore we analyzed the formation of compound nuclei including the memory effects. As for the intermediate memory effects some oscillations appear, which is very different from the Markovian dynamics. For super-heavy nuclei deexcitation, the existence of isomeric state within the potential barrier cannot explain the results of experiments performed at GANIL with the crystal blocking technique, and this despite of the fact that it modifies the deexcitation dynamics and increases the fission time. However, this latter study could be useful for the study of the actinides fission. In Part II, the phenomenological Skyrme effective interactions-associated M 1 and M 3 sum rules are being calculated based on their intrinsic definitions. We identify then M 1 up to the tensorial level and M 3 with central potential. In Part III, as for the hadronic matter hydrodynamics being applied to heavy ions collisions, and as a first approach only, we can neglect spontaneous chiral symmetry but certainly not the dissipative impact.

  6. Legal aspects of public health: difficulties in controlling vector-borne and zoonotic diseases in Brazil.

    Mendes, Marcílio S; de Moraes, Josué

    2014-11-01

    In recent years, vector-borne and zoonotic diseases have become a major challenge for public health. Dengue fever and leptospirosis are the most important communicable diseases in Brazil based on their prevalence and the healthy life years lost from disability. The primary strategy for preventing human exposure to these diseases is effective insect and rodent control in and around the home. However, health authorities have difficulties in controlling vector-borne and zoonotic diseases because residents often refuse access to their homes. This study discusses aspects related to the activities performed by Brazilian health authorities to combat vector-borne and zoonotic diseases, particularly difficulties in relation to the legal aspect, which often impede the quick and effective actions of these professionals. How might it be possible to reconcile the need to preserve public health and the rule on the inviolability of the home, especially in the case of abandoned properties or illegal residents and the refusal of residents to allow the health authority access? Do residents have the right to hinder the performance of health workers even in the face of a significant and visible focus of disease transmission? This paper argues that a comprehensive legal plan aimed at the control of invasive vector-borne and zoonotic diseases including synanthropic animals of public health importance should be considered. In addition, this paper aims to bridge the gap between lawyers and public health professionals and to facilitate communication between them. Copyright © 2014 Elsevier B.V. All rights reserved.

    2015-07-01

    Full Text Available Multiple sclerosis (MS patients, in general, show reduced physical function, physical activity, and quality of life. Positive associations between physical activity and quality of life have been reported. In particular, we were interested in the relation between physical activity and mental health in MS patients without limitation of physical function, since limitations of physical function may influence both physical activity and quality of life. Assessment comprised the Baecke questionnaire on physical activity, the Short Form 36 Health Survey (SF-36, and Beck Depression Inventory (BDI. We ranked our sample according to physical activity into four groups and performed an ANOVA to analyze the relationship between levels of physical activity and health-related quality of life (HRQoL. Then we performed a subgroup analysis and included patients with unlimited walking distance and a score of less than 18 in the BDI. Most active vs. inactive patients were compared for the mental subscales of the SF-36 and depression scores. From 632 patients, 265 met inclusion criteria and hence quartiles were filled with 67 patients each. Active and inactive patients did not differ considerably in physical function. In contrast, mental subscales of the SF-36 were higher in active patients. Remarkable and significant differences were found regarding vitality, general health perception, social functioning and mental health, all in favor of physically active patients. Our study showed that higher physical activity is still associated with higher mental health scores even if limitations of physical function are accounted for. Therefore, we believe that physical activity and exercise have considerable health benefits for MS patients.

    This study aims to: (1) examine rates of obesity and physical health complaints among 911 telecommunicators; and (2) document the role of emotion dysregulation, psychological inflexibility, duty-related distress and dissociation, and psychopathology in predicting obesity and physical health complaints in this population. The sample consisted of 911 telecommunicators from across the country (N = 758). Participants completed an online survey assessing their mental and physical health functioning. A total of 82.5% of the sample reported a body mass index that fell within the overweight or obese category and an average of 17 physical health complaints within the past month. Peritraumatic reactions (distress and dissociation), emotion dysregulation, and psychological inflexibility had effects on physical health largely through psychopathology (alcohol abuse, post-traumatic stress disorder, and depression). Development of adapted prevention and intervention efforts with this population is needed.

    2005-01-01

    Even though mathematics and physics have been related for centuries and this relation appears to be unproblematic, there are many questions still open: Is mathematics really necessary for physics, or could physics exist without mathematics? Should we think physically and then add the mathematics apt to formalise our physical intuition, or should we think mathematically and then interpret physically the obtained results? Do we get mathematical objects by abstraction from real objects, or vice versa? Why is mathematics effective into physics? These are all relevant questions, whose answers are necessary to fully understand the status of physics, particularly of contemporary physics. The aim of this book is to offer plausible answers to such questions through both historical analyses of relevant cases, and philosophical analyses of the relations between mathematics and physics.

    Physical therapists' familiarity, perceptions, and beliefs about health services utilization and health seeking behaviour have not been previously assessed. The purposes of this study were to identify physical therapists' characteristics related to familiarity of health services utilization and health seeking behaviour, and to assess what health seeking behaviour factors providers felt were related to health services utilization. We administered a survey based on the Andersen behavioural model of health services utilization to physical therapists using social media campaigns and email between March and June of 2017. In addition to descriptive statistics, we performed binomial logistic regression analysis. We asked respondents to rate familiarity with health services utilization and health seeking behaviour and collected additional characteristic variables. Physical therapists are more familiar with health services utilization than health seeking behaviour. Those who are familiar with either construct tend to be those who assess for health services utilization, use health services utilization for a prognosis, and believe that health seeking behaviour is measurable. Physical therapists rated need and enabling factors as having more influence on health services utilization than predisposing and health belief factors. Physical therapists are generally familiar with health services utilization and health seeking behaviour; however, there appears to be a disconnect between what is familiar, what is perceived to be important, and what can be assessed for both health services utilization and health seeking behaviour.

  15. Reflections on Physical Activity and Health: What Should We Recommend?

    Science.gov (United States)

    Warburton, Darren E R; Bredin, Shannon S D

    2016-04-01

    The health benefits of regular physical activity are irrefutable; virtually everyone can benefit from being active. The evidence is overwhelming with risk reductions of at least 20%-30% for more than 25 chronic medical conditions and premature mortality. Even higher risk reductions (ie, ≥ 50%) are observed when objective measures of physical fitness are taken. International physical activity guidelines generally recommend 150 minutes per week of moderate- to vigorous-intensity physical activity. A critical review of the literature indicates that half of this volume of physical activity might lead to marked health benefits. There is compelling evidence to support health promotion strategies that emphasize that health benefits can be accrued at a lower volume and/or intensity of physical activity. Public health policies are needed that reduce the barriers to physical activity participation such that everyone can reap the benefits of physical activity. It is also important to highlight that sedentary time (particularly sitting time) carries independent health risks. The simple message of "move more and sit less" likely is more understandable by contemporary society and is formed on the basis of a strong body of evidence. For practitioners who work directly with clients, it is recommended that an individualized prescription (dosage) that takes into consideration the unique characteristics and needs of the client is provided. Physical activity or exercise promotion should not be done in isolation; it should be part of an integrated approach to enhance healthy lifestyle behaviours.

The mentioned questionnaire (15 social questions, 14 historical questions, 11 cultural questions was constructed through a guide study and making subsequent revisions and editions. The opinions of the scope of experts were used in order to determine face and content validity and chronbach’s a was used in order to determine the reliability of the questionnaire. Appropriate descriptive and inferential statistics (ANOVA one- way, MANOVA and the Scheffe Hoc test were used. The findings demonstrated that the viewpoints of the members of the physical education were significantly different from those of the other two groups. The Scheffe Hoc test also demonstrated a significant difference between the ideas of the physical education members and those of the other two groups. The superiority of the physical education members in social part consisting of questions involving nationalism, Doping, professional sport, advertisement, commercialism, multimedia and communications was not due to their knowledge of Olympic chart but their involvement with these subjects in the society. Their superiority in historical questions was owing to the role of multimedia in covering the news and increasing the knowledge of the people in this respect. One of the reasons for the superiority of the physical education members in cultural section was that the addressees of multimedia got information on medals more than the cultural

This study aims to identify, classify and discuss social, cultural and educational factors relating to the health and quality of life of the elderly, establishing relationships with the motives for which they join and adhere to regular physical exercise programs in public areas. This was a field study employing descriptive quantitative and qualitative methodology and for which 120 participants from two physical exercise programs in Recife were interviewed. The results indicate that the most important motives for participation were as follows: to improve health (84.2%, to improve physical performance (70.8%, to adopt a healthy lifestyle (62.5%, to reduce stress (60.8%, to comply with doctor’s orders (56.7%, to recover from injury (55%, to improve self-image (50.8% and to enhance self-esteem and relax (47.5%. The most important motives for continuing to attend such programs were: to improve posture (75%; to promote a feeling of wellbeing (74.2%; to keep fi t (70.8%; to experience pleasure (66.7%; to become stronger and be motivated by the instructor (62.5%; to experience a feeling of well-being produced by the social environment (60%; and to experience self-realization and receive attention from the instructor (57.5%. For the men (35.1%, the habit of performing physical exercise in their youth had no bearing on their joining such programs.

    Full Text Available Abstract Background The benefits of a recommended level of physical activity on physiological health indicators such as morbidity and mortality are well-accepted, but less research has addressed whether or not the association between the recommended level of physical activity and a health-related quality of life (HRQOL exists in the Japanese population. Thus, the present study examined whether the recommended physical activity would be associated with HRQOL in the general Japanese middle-aged population. Methods Data were obtained from 1211 male and female respondents (39.4 ± 10.9 year, mean ± SD from an Internet-based survey of registrants of an Internet research service. Physical activity level was estimated from the short form of the International Physical Activity Questionnaire. HRQOL was assessed with the Medical Outcomes Survey Short Form-8 questionnaire (SF-8. Based on the current national guidelines for exercise in Japan, respondents were divided into a recommended group, an insufficient group, and an inactive group according to their estimated weekly physical activity level. Multivariate analyses of covariance were utilized. Results Across both genders, the recommended group had significantly higher physical functioning (PF scores than the inactive group (p Conclusion Individuals who attained the recommended level of physical activity had better scores on some dimensions of HRQOL than those who did not, suggesting that the recommended level of physical activity may be applicable not only to the physiological objective outcomes but also to some dimensions in both the physical and mental aspects of HRQOL.

    Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes.

    Improved physical health care is a pressing need for patients with schizophrenia. It can be achieved by means of a multidisciplinary team led by the psychiatrist. Key priorities should include: selection of antipsychotic therapy with a low risk of weight gain and metabolic adverse effects; routine assessment, recording and longitudinal tracking of key physical health parameters, ideally by electronic spreadsheets; and intervention to control CVD risk following the same principles as for the general population. A few simple tools to assess and record key physical parameters, combined with lifestyle intervention and pharmacological treatment as indicated, could significantly improve physical outcomes. Effective implementation of strategies to optimise physical health parameters in patients with severe enduring mental illness requires engagement and communication between psychiatrists and primary care in most health settings.

    2016-10-01

    People with mental illness have a significantly lower life expectancy and higher rates of chronic physical illnesses than the general population. Health care system reform to improve access and quality is greatly needed to address this inequity. The inclusion of consumers of mental health services as co-investigators in research is likely to enhance service reform. In light of this, the current paper reviews mental health consumer focussed research conducted to date, addressing the neglect of physical health in mental health care and initiatives with the aim of improving physical health care. The international literature on physical healthcare in the context of mental health services was searched for articles, including mental health consumers in research roles, via Medline, CINAHL and Google Scholar, in October 2015. Four studies where mental health consumers participated as researchers were identified. Three studies involved qualitative research on barriers and facilitators to physical health care access, and a fourth study on developing technologies for more effective communication between GPs and patients. This review found that participatory mental health consumer research in physical health care reform has only become visible in the academic literature in 2015. Heightened consideration of mental health consumer participation in research is required by health care providers and researchers. Mental health nurses can provide leadership in increasing mental health consumer research on integrated care directed towards reducing the health gap between people with and without mental illness. © 2016 Australian College of Mental Health Nurses Inc.

    2009-03-01

    This study examined the effect of health worry (i.e., cognitive aspect of anxiety resulting from concern for health) on walking difficulty in a nationally representative sample (N = 7,527) of older adults (M age = 76.83 years). The study further tested whether physical activity mediates the effect of health worry on walking difficulty in a 6-year follow-up design. Results of a mediation analysis using structural equation modeling showed that people with a high degree of health worry engaged in less physical activity (beta = -.24, p < .001), and people who participated in less physical activity were more likely to report walking difficulty at the 6-year follow-up (beta = -.22, p < .001). There was a significant indirect effect from health worry to walking difficulty through physical activity (beta = .05, p < .001), controlling for demographic, psychosocial, and health related factors. Results suggested that inducing threat and worry may not be effective for physical activity promotion in the older population. More promising coping and regulation strategies are discussed.

    Patients with mental illnesses are at high risk for physical disorders and death. The aim of this study is to describe mental health nurses' attitudes and practice toward physical health care for patients with mental illnesses. A descriptive cross-sectional design was used to collect data using self- reported questionnaire from 202 mental health nurses working in mental health settings in Jordan. The study adopted translated version of Robson and Haddad Physical Health Attitudes Scale to the Arabic language. There was significant positive correlation between the participants' positive attitudes and their current practice (r = .388, p = .000), mental health nurses who have more positive attitudes regarding physical health care involved physical health care more in their current practice. Mental health nurses' attitudes affect the quality of care provided to patients with mental illnesses. The results provide implications for practice, education, and research.

    2016-03-01

    This article explores the use of a physical examination assignment in a mental health general nursing clinical placement course that addresses the poor physical health of people with mental illness and the barriers traditionally impeding health care provision for this population. A descriptive qualitative approach utilizes inductive content analysis to investigate 145 student survey responses. The assignment assists student nurses in understanding that physical and mental well-being are intrinsically linked. Students report increased comfort performing a physical examination on patients with mental illness post assignment. Students' initial bias towards this population was minimized post the clinical assignment. Poor physical health is common among people with mental health problems. Many view the provision of care as a major public health issue. Nurses are the front line caregivers of mental health service consumers and are well positioned to assess their physical needs. Their assessment may be the first step in recognizing health care issues in this population. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Physical activity in adolescence may contribute to the development of healthy adult lifestyles, helping reduce chronic disease incidence. However, definition of the optimal amount of physical activity in adolescence requires addressing a number of scientific challenges. This article reviews the evidence on short- and long-term health effects of adolescent physical activity. Systematic reviews of the literature were undertaken using a reference period between 2000 and 2004, based primarily on the MEDLINE/PubMed database. Relevant studies were identified by examination of titles, abstracts and full papers, according to inclusion criteria defined a priori. A conceptual framework is proposed to outline how adolescent physical activity may contribute to adult health, including the following pathways: (i) pathway A--tracking of physical activity from adolescence to adulthood; (ii) pathway B--direct influence of adolescent physical activity on adult morbidity; (iii) pathway C--role of physical activity in treating adolescent morbidity; and (iv) pathway D - short-term benefits of physical activity in adolescence on health. The literature reviews showed consistent evidence supporting pathway 'A', although the magnitude of the association appears to be moderate. Thus, there is an indirect effect on all health benefits resulting from adult physical activity. Regarding pathway 'B', adolescent physical activity seems to provide long-term benefits on bone health, breast cancer and sedentary behaviours. In terms of pathway 'C', water physical activities in adolescence are effective in the treatment of asthma, and exercise is recommended in the treatment of cystic fibrosis. Self-esteem is also positively affected by adolescent physical activity. Regarding pathway 'D', adolescent physical activity provides short-term benefits; the strongest evidence refers to bone and mental health. Appreciation of different mechanisms through which adolescent physical activity may influence adult

    Full Text Available Objective: This study aimed to evaluate the quality of life, through the “Medical Outcomes Study 36 - Item Short - Form Health Survey” (SF-36 questionnaire, of a group of elderly involved in physical activities scheduled and the impact of physical activity time. Methods: We assessed 143 elderly engaged in physical activity programmed by Universidade Federal de Uberlândia. As a data collection tool, we used the SF-36 and a sociodemographic questionnaire, applied at the time of the interview. Statistical analysis was performed using Kruskal-Wallis, for analysis between domains, and Mann-Whitney test, to verify the relationship between health status and physical activity level. Results: The average age was 70.5 years. The mean score for the SF-36 of the elderly people who participated in the research was 73.3. The best result was in the Social Aspects domain (81.7, followed by Mental Health (78.9. Approximately 76% had at least 150 minutes of physical activity per week, being classified as a more active population. Most (70.6% of the elderly had a good perception of their general health. There was statistical difference in the General Health domain among groups that performed physical activity for a period of less than one year and those who have been engaging in regular physical activity for over 10 years. Conclusions: The Social Function and Mental Health domains had the highest scores, with significant documentation of a better general health in the group that have practiced consecutive physical activity for over ten years.

    Health-related quality of life (HRQoL) has been characterized as the ultimate goal for health interventions such as physical activity (PA). We assessed how frequency, duration, and intensity of PA were related to HRQoL in younger (physical and mental health. HRQoL was measured by SF-8 Health Survey. Frequency and duration were assessed by items validated in a previous HUNT study, and intensity was assessed by Borg RPE scale. Associations between PA and physical and mental health were estimated using general linear modeling. A total of 4500 participants (56% females), age 19-91 yr, with mean age of 53±15 yr, were included. Of these, 40% were less active than recommended by international guidelines. In general, mean physical health (PCS-8) in females and males was 47.4±9.7 and 48.8±8.9, and mental health (MCS-8) was 50.5±8.0 and 51.9±7.3, respectively. Age-adjusted association between PA and HRQoL was stronger for physical than mental health in both genders and age groups. The largest differences were between no exercise and exercise groups at any level for frequency, duration, and intensity of PA. We found no substantial gender differences in association between PA and HRQoL, but association was stronger in older (≥65 yr) than younger (physical and mental health in both genders compared with no exercise, particularly among the older individuals.

    American Indian (AI) boarding school attendance is related to poor physical health status; however, little is known about how specific aspects of this experience contribute to poor health. Five experiences (age of first attendance, limited family visits, forced church attendance, prohibition on practicing AI culture and traditions, and punishment for use of AI language) may be independently associated with physical health status in adulthood. We expected the effect to be greater for those who began boarding school at older ages. Data on AI boarding school attenders (n = 771) came from the AI-Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project. Multiple linear regression models examined the association of these five experiences with physical health status. Additionally, we conducted a separate set of regressions to test for an interaction effect of age of first attendance. Each of the five experiences noted above were independently associated with poorer physical health status compared to those who did not have these experiences. An interaction effect for those punished for use of AI language and who were aged 8 or older was confirmed. Findings are consistent with reports that boarding school attendance is related to poor AI adult health. To inform AI health programs, the relationship of specific diseases and boarding school attendance should be considered.

    Previous studies have described various associations between tax policy and health. Here we propose a unifying conceptual framework of 'Five R's' to stimulate awareness about the importance of tax to health improvement. First, tax can improve representation and democratic accountability, and help make governments more responsive to the needs of its citizens. Second, tax can create a revenue stream for a universal pool of public finance for health care and other public services. Third, progressive taxation when combined with appropriate public spending can help redistribute wealth and income and mitigate social and health inequalities. Fourth, the re-pricing of harmful products (e.g. tobacco, alcohol and unhealthy food) can help reduce their consumption. Fifth, taxation provides a route by which certain harmful industries can be regulated. The paper also discusses the barriers that hinder the full potential for taxation to be used to improve health, including: weak tax administrations, large 'shadow economies', international trade liberalisation, tax avoidance, transfer pricing by transnational corporations and banking secrecy. We suggest that a greater awareness of the manifold associations between tax and health will encourage health practitioners to actively promote fairer and better taxation, thereby helping to improve health and reduce health inequalities.

    Full Text Available Considering the worker’s health one of the Unified Health System (SUS tasks, the Primary Health Care (PHC and the Family Health Strategy (FHS play an important role in the development of health actions in the field health-work. In Brazil, where the number of informal and domiciled jobs is high, the FHS becomes a reference in the workers’ health actions. Therefore, if the FHS is not attentive to the relation between professional occupation and disease, several diseases that affect workers can overload the system without obtaining a cure. The aim of this study is to evaluate doctors and nurses recognition of the Family Health Strategy on occupational diseases in Aparecida de Goiânia. This is a qualitative descriptive study and the data analysis was done by content analysis. The setting for this study contemplates FHS units in the municipality of Aparecida de Goiânia, Goiás. There were 8 Basic Health Units and 16 health professionals were interviewed. The data was collected in the participants of the interview workplaces, from February through April, 2013, after being approved by the Ethics and Research Committee. The discourses were analyzed according to Minayo (2007, using thematic analysis. The interviews were recorded and later transcribed for analysis. Among the 16 professionals interviewed we observed that only 3 (18.75% received professional training on occupational health in their Institution, however the aim of the courses were towards situations of biological hazards and not about workers care. Practitioners reported lack of knowledge in the occupational health area, and also observed that the area is still undervalued and underexplored in the academic and professional fields, and even by the Municipality health management. Evaluating the academic education it is possible to observe the inadequacy of the subject workload, where professionals reported the lack of knowledge in the area and the low workload of the subject in the

    Cities with a Mediterranean-type climate (Med-cities) are particularly susceptible to health risks from climate change since they are located in biogeographical hot-spots that experience some of the strongest effects of the changing climate. The study aims to highlight health impacts of climate change in Med-cities, analyze local climate adaptation plans and make adaptation policy recommendations for the Med-city level. We identified five Med-cities with a climate change adaptation plan: Adelaide, Barcelona, Cape Town, Los Angeles and Santiago. Beyond their similar Med-climate features (although Santiago's are slightly different), the cities have different socio-economic characteristics in various aspects. We analyzed each plan according to how it addresses climate change-related drivers of health impacts among city dwellers. For each driver, we identified the types of policy adaptation tools that address it in the urban climate adaptation plans. The surveyed cities address most of the fundamental climate change-related drivers of risks to human health, including rising temperatures, flooding and drought, but the policy measures to reduce negative impacts vary across cities. We suggest recommendations for Med-cities in various aspects, depending on their local needs and vulnerability challenges: assessment of health risks, extreme events management and long-term adaptation, among others.

    Full Text Available Extracellular matrix can influence stem cell choices, such as self-renewal, quiescence, migration, proliferation, phenotype maintenance, differentiation, or apoptosis. Three aspects of extracellular matrix were extensively studied during the last decade: physical properties, spatial presentation of adhesive epitopes, and molecular complexity. Over 15 different parameters have been shown to influence stem cell choices. Physical aspects include stiffness (or elasticity, viscoelasticity, pore size, porosity, amplitude and frequency of static and dynamic deformations applied to the matrix. Spatial aspects include scaffold dimensionality (2D or 3D and thickness; cell polarity; area, shape, and microscale topography of cell adhesion surface; epitope concentration, epitope clustering characteristics (number of epitopes per cluster, spacing between epitopes within cluster, spacing between separate clusters, cluster patterns, and level of disorder in epitope arrangement, and nanotopography. Biochemical characteristics of natural extracellular matrix molecules regard diversity and structural complexity of matrix molecules, affinity and specificity of epitope interaction with cell receptors, role of non-affinity domains, complexity of supramolecular organization, and co-signaling by growth factors or matrix epitopes. Synergy between several matrix aspects enables stem cells to retain their function in vivo and may be a key to generation of long-term, robust, and effective in vitro stem cell culture systems.

    To explore nurses' views of their role in the screening and monitoring of the physical care needs of people with serious mental illness in a mental health service provider. There is increasing awareness through research that people with serious mental illness disproportionately experience and die early from physical health conditions. Mental health nurses are best placed as front-line workers to offer screening, monitoring and interventions; however, their views on physical care interventions are not studied often. Qualitative exploratory study. The study was carried out in a mental health inpatient centre in England. Volunteer sampling was adopted for the study with a total target sample of (n = 20) nurses from three inpatient wards. Semistructured interviews were conducted with (n = 10) registered mental health nurses who had consented to take part in the study. Inductive data analysis and theme development were guided by a thematic analytic framework. Participants shared a clear commitment regarding their role regarding physical health screening and monitoring in mental health settings. Four themes emerged as follows: features of current practice and physical health monitoring; perceived barriers to physical health monitoring; education and training needs; and strategies to improve physical health monitoring. Nurses were unequivocal in their resolve to ensure good standard physical health monitoring and screening interventions in practice. However, identified obstacles have to be addressed to ensure that physical health screening and monitoring is integrated adequately in everyday clinical activities. Achieving this would require improvements in nurses' training, and an integrated multiservice and team-working approach. Attending to the physical health needs of people with serious mental illness has been associated with multiple improvements in both mental and physical health; nurses have a vital role to play in identifying and addressing causes of poor

Correlation analysis showed that parental social class, childhood cognitive ability, education and occupation, and two personality traits (Emotional Stability/Neuroticism, and Conscientiousness were all significantly associated with adult physical health variables. Structural equation modelling showed that health conditions and personality traits were significantly, and inversely, associated with physical health (indicated by good daily physical functioning, relative absence of pain, perceived health, and low level of limitations at work due to physical health. Parental social status, childhood intelligence, educational and occupational attainment were all modestly, but significantly and directly, associated with adult physical health. The effect of childhood intelligence on adult physical health was, in part, mediated through Emotional Stability and Conscientiousness. After controlling for health conditions Emotional Stability was the strongest predictor of physical health. Implications and limitations are discussed.

    To review the literature on the effects of parental divorce over the psychological maladjustment and physical health problems in children of divorced parents, thus contributing to the integration of existing scientific knowledge based on the biopsychosocial model of the impact of divorce on children's physical health as proposed by Troxel and Matthews (2004). Review of the literature using MEDLINE and PsycInfo (1980-2007) databases, selecting the most representative articles on the subject. Special attention was paid to contributions by internationally renowned investigators on the subject. Divorce may be responsible for a decline of physical and psychological health in children. The developmental maladjustment of children is not triggered by divorce itself, but rather by other risk factors associated with it, such as interparental conflict, parental psychopathology, decline in socio-economic level, inconsistency in parenting styles, a parallel and conflicting co-parenting relationship between parents and low levels of social support. Such risk factors trigger maladjusted developmental pathways, marked by psychopathological symptoms, poor academic performance, worst levels of physical health, risk behavior, exacerbated psychophysiological responses to stress and weakening of the immune system. Clear links were observed between experiencing parental divorce and facing problems of physical and psychological maladjustment in children. Divorce is a stressor that should be considered by health professionals as potentially responsible for maladjusted neuropsychobiological responses and for decline in children's physical health.

    The provision and receipt of emotion work-defined as intentional activities done to promote another's emotional well-being-are central dimensions of marriage. However, emotion work in response to physical health problems is a largely unexplored, yet likely important, aspect of the marital experience. We analyze dyadic in-depth interviews with husbands and wives in 21 mid- to later-life couples to examine the ways that health-impaired people and their spouses provide, interpret, and explain emotion work. Because physical health problems, emotion work, and marital dynamics are gendered, we consider how these processes differ for women and men. We find that wives provide emotion work regardless of their own health status. Husbands provide emotion work less consistently, typically only when the husbands see themselves as their wife's primary source of stability or when the husbands view their marriage as balanced. Notions of traditional masculinity preclude some husbands from providing emotion work even when their wife is health-impaired. This study articulates emotion work around physical health problems as one factor that sustains and exacerbates gender inequalities in marriage with implications for emotional and physical well-being.

    2017-10-01

    This study compared mental health and physical health literacy using five health problems from each area. The aim was to determine whether the same group had better physical than mental health literacy Method: A sample of 263 participants completed an online questionnaire requiring them to name a problem/illness described in 10 vignettes and suggest treatment options. Five vignettes described mental health problems (anxiety, bipolar-disorder, depression, OCPD and schizophrenia) and five physical problems (angina, COPD, diabetes, a heart attack, and sinusitis). Participants were also asked to rate their sympathy and estimates of prevalence for each disorder. Recognition of the mental health disorders was superior compared recognition of the physical disorders. Analysis of treatment beliefs, sympathy and prevalence ratings also showed significant differences between disorders. Results highlight the importance of education and the lack of public knowledge regarding major physical health conditions.

    Aim: To examine the existing situation, barriers and consequences of the intercultural communication in health institutions and to offer training models for strengthening and improving communication skills of health professionals in the Republic of Macedonia. Methods: A cross-sectional survey was conducted to assess the relationship between patients and health professionals. A total of 813 health professionals (302 physicians and 511 other medical staff) from different healthcare institutions, and 1016 patients participated in cross-sectional survey performed in autumn 2010. Results: The research has showed that each third examined patient thought that his/her physician or the other medical personnel had no understanding for his/her emotions and gave no answer to all of his/her questions. From the other side, 60% of the physicians declare that they have a good communication with patients speaking other language than their mother tongue. Only 60% of physicians said that they know good the culture of their patient and 52% of the other medical staff said that they adjusted the treatment to the patient culture (religion, attitudes, language, life style). Conclusion: There are some gaps in current provision of health care practice in an aspect of effective interactions and communication skills of health professionals to meet patient needs in a multicultural and multilingual setting. A training model is proposed for strengthening communication skills of health professionals. PMID:24511268

    Much recent interest has focused on the relationship between physical activity and health and supported with an abundance of scientific evidence. However, the concept of Exercise is Medicine™ copromoted by the American College of Sports Medicine and American Medical Association and similar august bodies worldwide is far from new--the importance of exercise for health has been reported for centuries. Participation in regular physical activity and exercise provides numerous benefits for health with such benefits typically varying according to the volume completed as reflected by intensity, duration, and frequency. Evidence suggests a dose-response relationship such that being active, even to a modest level, is preferable to being inactive or sedentary. Greatest benefits are commonly associated with the previously sedentary individual assuming a more active lifestyle. There is an apparent linear relationship between physical activity and health status and as a general rule, increases in physical activity and fitness result in additional improvements in health status. This narrative review provides a selective appraisal of the evidence for the importance of physical activity for health, commencing with a baseline historical perspective followed by a summary of key health benefits associated with an active lifestyle. © 2015 Elsevier Inc.

      Ever since pioneers like Rolf Wideröe and Ernest Lawrence built the first particle accelerators in the 1920s and 30s, particle physics has contributed to advances in medicine. Today, over half of the world’s particle accelerators are used in medicine, and more and varied uses are being found for them all the time. The same is true for particle detector technology. In the 1970s, CERN played an important role in the emerging technology of positron emission tomography (PET), building prototype scanners in a collaboration with Geneva’s hospital. That tradition continues to this day, with crystal technology developed for LEP, coupled to electronics developed for the LHC, pointing the way to combined PET/MRI scanners. It’s a proud track record by any standards, but we can do better. In the past, the transfer of knowledge and technology between the biomedical professions and physics has been sporadic: based on chance rather than strategy. That’s why...

    Along with the digital revolution, information and communication technology applications are currently transforming the delivery of health and social care services. This paper investigates prevailing opinions toward future technology-based healthcare solutions among Austrian healthcare professionals. During a biphasic online Delphi survey, panelists rated expected outcomes of two future scenarios describing pervasive health monitoring applications. Experts perceived that the scenarios were highly innovative, but only moderately desirable, and that their implementation could especially improve patients' knowledge, quality of healthcare, and living standard. Contrarily, monetary aspects, technical prerequisites, and data security were identified as key obstacles. We further compared the impact of professional affiliation. Clearly, opinions toward pervasive healthcare differed between the interest groups, medical professionals, patient advocates, and administrative personnel. These data suggest closer collaborations between stakeholder groups to harmonize differences in expectations regarding pervasive health monitoring.

  5. The role of law in addressing mental health-related aspects of disasters and promoting resilience.

    2012-01-01

    Law plays a critical role in emergency preparedness and disaster response by establishing an infrastructure for the response and facilitating coordination among the federal, state, and local governments. Once a disaster occurs, certain legal mechanisms are activated to ensure that individuals' needs for mental health care are met, both for pre-existing and emergent conditions. This includes the rapid deployment of mental health care personnel and the implementation of crisis counseling programs in affected regions. By facilitating an influx of resources, including personnel, supplies, and financial assistance, the law can help communities quickly rebound and return to a sense of normal. Drawing on examples from the United States, this article illustrates the diverse ways in which the law simultaneously addresses mental health-related aspects of disasters and promotes resilience within affected communities.

    Compromised physical health and raised levels of morbidity and mortality are experienced by young people (16-24 years) with mental illness, and are compounded by psychotropic medication. How this group conceives and experiences physical health is not well understood. We investigated the meanings, beliefs, and endeavours of young people that impact their physical health understandings and behaviours. The present study formed the qualitative phase of a sequential mixed-methods study, and incorporated semistructured interviews with 12 hospitalized young people. Qualitative content analysis was used to analyse data. Participants held a holistic ideal of physical health that they did not meet. Weight change, poor sleep, and limited exercise adversely impacted their lives and self-image. Sedentary behaviour, reduced energy, and limited health literacy compromised effective management of physical health. Young people needed structure and support to assist them in addressing their physical health needs when amotivation overwhelmed their internal resources. Nurses are well placed to help young people increase their competency for health management. Individualized information and methods to promote good physical health are required for this group in jeopardy from physical morbidity and mortality. © 2016 Australian College of Mental Health Nurses Inc.

    2016-01-01

    Temperament traits and mental illness have been linked to varying degrees of imbalances in neurotransmitter systems of behavior regulation. If a temperament model has been carefully structured to reflect weak imbalances within systems of behavior regulation, then in the presence of mental illness, these profiles should exhibit distinct patterns consistent with symptoms of mental illness. In contrast to other temperament models used in studies of anxiety disorders, the Functional Ensemble of Temperament (FET) model differentiates not only between emotionality traits, but also between traits related to physical, social-verbal and mental aspects of behavior. This paper analyzed the predictions of the FET model, which maps 12 functional aspects of behavior to symptoms of generalized anxiety disorder (GAD) as described in the DSM/ICD. As an example, the paper describes a study of the coupling of sex, age and temperament traits with GAD using the FET framework. The intake records of 116 clients in treatment with confirmed diagnosis of GAD in a private psychological practice were compared using ANOVA against records of 146 healthy clients using their scores on the FET-based questionnaire, in age groups 17-24, 25-45, 46-65. Patients with GAD in all age groups reported significantly lower Social Endurance, Social Tempo, Probabilistic reasoning (but not in physical aspects of behavior) and higher Neuroticism than healthy individuals, however, no effects on the scales of Motor Endurance or Tempo were found. These findings show the benefits of differentiation between motor-physical and social-verbal aspects of behavior in psychological assessment of mental disorders.

    Turner syndrome (TS) is a complex medical condition with specific cognitive and psychosocial characteristics and frequent medical morbidity. Few studies have investigated the influence this has on health status, education and ability to work. To explore health status, level of education, work participation, medical conditions, physical activity, satisfaction with life and aspects of sexual functioning in adult TS women and compare with a matched control group. A questionnaire was sent to 168 adult women with TS >18 years registered in a database of Frambu Resource Centre for Rare Disorders and The TS Association in Norway. We assessed health status with Short Form 36, education with Norwegian Standard Classification of Education, and employment with The General Nordic Questionnaire. Life satisfaction was measured with LiSat-9, and questions on psychological strain during life phases were included. Eighty women with TS (34.0 +/- 11.7 years) and 214 controls (32.9 +/- 10.6) responded. The TS group reported significantly more health problems and impaired health status in the two subscales "physical functioning" and "general health" (P education and work participation was similar among TS and controls. TS moved away from their parents' home later than controls (20.4 +/- 4.0 vs. 18.7 +/- 2.1, P = 0.001). Age at sexual debut differed significantly (21.2 +/- 4.3 vs. 17.3 +/- 2.4 years, P education and level of employment as controls, they report more frequent occurrence of medical conditions, but scored lower on only two subscales in the SF-36. Despite considerable medical morbidity, TS seem to cope well with life.

This monograph describes the multidisciplinary study of aspects of childhood health and its relationship to cognitive and brain function, and scholastic performance. Specifically, we focus on physical activity and physical fitness along with nutrition and obesity; interconnected aspects of health that have declined over the past 30 years in children of industrialized nations. Although much emphasis has been placed on correcting physical aspects of these public health concerns, it is only more recently that attention has been paid to the relation between physical health and cognitive health among school age children. The monograph begins with an overview of current behavioral trends that compete with physical activity engagement and contribute to the failure to achieve the public health recommendations for physical activity among children in the United States. Following the epidemiological overview, the relation of childhood fitness to brain structure and function is examined among children with varying fitness levels. The observed dissimilarities between higher- and lower-fit children are discussed within the context of typical brain development. To broaden the scope of research presented herein, the relation of nutrient intake--among both undernourished and well-nourished children--and obesity on cognition and brain are discussed. Next, novel empirical data are presented from a correlational study that indicates a differential relation between childhood fitness and adiposity on various aspects of cognition. In an effort to provide a more comprehensive review, a later chapter is dedicated to describing a small body of literature investigating the relation of physical activity to special populations of children, including those with learning disorders. In doing so, practical applications as well as challenges and limitations of implementing physical

    To better understand the combined influence of employee engagement, health behavior, and physical health on job performance and absenteeism. Analyses were based on 20,114 employees who completed the Healthways Well-Being Assessment from 2008 to 2010. Employees represented three geographically dispersed companies in the United States. Employee engagement, health behavior, and physical health indices were simultaneously significantly associated with job performance and also with absenteeism. Employee engagement had a greater association with job performance than did the health behavior or physical health indices, whereas the physical health index was more strongly associated with absenteeism. Specific elements of the indices were evaluated for association with self-rated job performance and absenteeism. Efforts to improve worker productivity should take a holistic approach encompassing employee health improvement and engagement strategies.

    Research development is needed in physical activity and sedentary behaviour and their associations with mental health in young people. In Western countries the weather is a key contributing factor of sedentary behaviour in youth. The likely contributing factor of sedentary behaviour among African youth has not been explored. This study examined the association between sedentary behaviour and mental health in African young people. Participants were 296 adolescents (150 males, 146 females) aged 13 to 18 years (mean = 14.85 years) living in Ghana. Participants' physical activity levels were assessed using the Physical Activity Questionnaire for Older Adolescents (PAQ-A) and sedentary behaviour, using the Adolescents Sedentary Activity Questionnaire. Depression was assessed using the Children Depression Inventory and aspects of self-esteem were measured with the Physical Self-worth test and Body Image Silhouette test. There was a significant negative correlation between physical activity and mental health independent of sedentary behaviour [depression (r =-0.78, p < 0.001); physical self-worth (r = 0.71, p < 0.001); body dissatisfaction (r =-0.76, p < 0.001)]. Moreover, sedentary behaviour was significantly associated with higher depression (r = 0.68, p < 0.001). Affluence was a significant contributing factor of sedentary behaviour in African young people [t (294) =-7.30, p < 0.001]. The present study has found that sedentary behaviour is highly prevalent among African adolescents especially among adolescents from affluent homes. Low levels of physical activity as well as sedentary behaviour is significantly associated with mental health problems among African youth, which is consistent with reports from studies among Western young people. The present research, therefore, contributes new information to the existing literature. Increased physical activities can improve the mental health of adolescents.

    The health of a carer is a key factor which can affect the well-being of the child with disabilities for whom they care. In low-income countries, many carers of children with disabilities contend with poverty, limited public services and lack assistive devices. In these situations caregiving may require more physical work than in high-income countries and so carry greater risk of physical injury or health problems. There is some evidence that poverty and limited access to health care and equipment may affect the physical health of those who care for children with disabilities. This study seeks to understand this relationship more clearly. A mixed methods study design was used to identify the potential physical health effects of caring for a child with moderate-severe motor impairments in Kilifi, Kenya. Qualitative data from in-depth interviews were thematically analysed and triangulated with data collected during structured physiotherapy assessment. Carers commonly reported chronic spinal pain of moderate to severe intensity, which affected essential activities. However, carers differed in how they perceived their physical health to be affected by caregiving, also reporting positive benefits or denying detrimental effects. Carers focussed on support in two key areas; the provision of simple equipment and support for their children to physically access and attend school. Carers of children with moderate-severe motor impairments live with their own physical health challenges. While routine assessments lead to diagnosis of simple musculoskeletal pain syndromes, the overall health status and situation of carers may be more complex. As a consequence, the role of rehabilitation therapists may need to be expanded to effectively evaluate and support carers' health needs. The provision of equipment to improve their child's mobility, respite care or transport to enable school attendance is likely to be helpful to carers and children alike. © 2012 Blackwell Publishing Ltd.

    To assess aspirations for physical health over 18 months. To examine whether maintained importance of aspirations for physical health mediated and/or moderated the effect of an intensive intervention on long-term tobacco abstinence. Participants were randomly assigned to an intervention based on self-determination theory or to community care, and provided data at baseline and at 18 and 30 months post-randomization. Aspirations for physical health were better maintained over 18 months among participants in the intervention (mean change=.05), relative to community care (mean change=-.13), t=2.66, p<.01. Maintained importance of aspirations for physical health partially mediated the treatment condition effects on seven-day point prevalence tobacco abstinence (z'=1.68, p<.01) and the longest number of days not smoking (z'=2.16, p<.01), and interacted with treatment condition to facilitate the longest number of days not smoking (beta=.08, p<.05). Maintained importance of aspirations for physical health facilitated tobacco abstinence. Smokers may benefit from discussing aspirations for physical health within autonomy-supportive interventions. Patients may benefit from discussing aspirations during counseling about therapeutic lifestyle change and medication use.

  15. Potential Moderators of Physical Activity on Brain Health

    Full Text Available Age-related cognitive decline is linked to numerous molecular, structural, and functional changes in the brain. However, physical activity is a promising method of reducing unfavorable age-related changes. Physical activity exerts its effects on the brain through many molecular pathways, some of which are regulated by genetic variants in humans. In this paper, we highlight genes including apolipoprotein E (APOE, brain derived neurotrophic factor (BDNF, and catechol-O-methyltransferase (COMT along with dietary omega-3 fatty acid, docosahexaenoic acid (DHA, as potential moderators of the effect of physical activity on brain health. There are a growing number of studies indicating that physical activity might mitigate the genetic risks for disease and brain dysfunction and that the combination of greater amounts of DHA intake with physical activity might promote better brain function than either treatment alone. Understanding whether genes or other lifestyles moderate the effects of physical activity on neurocognitive health is necessary for delineating the pathways by which brain health can be enhanced and for grasping the individual variation in the effectiveness of physical activity interventions on the brain and cognition. There is a need for future research to continue to assess the factors that moderate the effects of physical activity on neurocognitive function.

    Considering the worker's health one of the Unified Health System (SUS) tasks, the Primary Health Care (PHC) and the Family Health Strategy (FHS) play an important role in the development of health actions in the field health-work. In Brazil, where the number of informal and domiciled jobs is high, the FHS becomes a reference in the workers' health actions. Therefore, if the FHS is not attentive to the relation between professional occupation and disease, several diseases that affect workers can overload the system without obtaining a cure. The aim of this study is to evaluate doctors and nurses recognition of the Family Health Strategy on occupational diseases in Aparecida de Goiânia. This is a qualitative descriptive study and the data analysis was done by content analysis. The setting for this study contemplates FHS units in the municipality of Aparecida de Goiânia, Goiás. There were 8 Basic Health Units and 16 health professionals were interviewed. The data was collected in the participants of the interview workplaces, from February through April, 2013, after being approved by the Ethics and Research Committee. The discourses were analyzed according to Minayo (2007), using thematic analysis. The interviews were recorded and later transcribed for analysis. Among the 16 professionals interviewed we observed that only 3 (18.75%) received professional training on occupational health in their Institution, however the aim of the courses were towards situations of biological hazards and not about workers care. Practitioners reported lack of knowledge in the occupational health area, and also observed that the area is still undervalued and underexplored in the academic and professional fields, and even by the Municipality health management. Evaluating the academic education it is possible to observe the inadequacy of the subject workload, where professionals reported the lack of knowledge in the area and the low workload of the subject in the academic field. There is

    Purpose: To describe the physical and clinical aspects of the dynamic intensity modulated radiotherapy of 21 patients. Methods and Materials: Dynamic, intensity modulated radiotherapy (IMR) was given to 21 patients with advanced or recurrent disease. 13 patients were immobilized with head screws, and 8, with non-invasive thermoplastic masks. The system was selected because it was designed de novo from a well established simulated annealing optimization model (SA), and with stringent leakage requirements and rapid leaf transit time for a multi leaf collimator (MLC). The system included a 6 MV linear accelerator (linac), an MLC, a quad processing computer system with SA software, a computer MLC controller with inclinometers and interlocks to stop radiation upon potential MLC or linac gantry fault detection, and immobilization devices attached to CT and treatment tables. The MLC was built around a 2 x 20 array of leaves with 9 half value layers of attenuation of the primary beam (99.8%). Over a trillion (2 40 ) beamlet patterns were dynamically changeable per deg. of linac gantry rotation. With all leaves shut, transmission was within a secondary collimator standard of < 0.5% of the primary beam. MLC control was via touch screen computer, and a disk drive which read beam pattern sequences from a disk generated by the planning system. Planning included 3D CT and magnetic resonance localization of regions of interest (ROI). The SA cost function incorporated idealized dose-volume parameter sets of up to 21 ROI/patient. Relative importance and spatial pre-eminance of each ROI were quantified into the constraint set, together with an instrument data file (IDR) built from depth dose and crossplot data of 8 x 8 to 20 x 200 mm field sizes and patterns measured with small diodes in a water tanc phantom. Planner output included dose volume histograms, tabulated dosimetry statistics, 2D dose distributions, and 3D translucent renderings of patient surfaces with underlying colored

  20. Reconciling "stress" and "health" in physical anthropology: what can bioarchaeologists learn from the other subdisciplines?

    The concepts of "stress" and "health" are foundational in physical anthropology as guidelines for interpreting human behavior and biocultural adaptation in the past and present. Though related, stress and health are not coterminous, and while the term "health" encompasses some aspects of "stress," health refers to a more holistic condition beyond just physiological disruption, and is of considerable significance in contributing to anthropologists' understanding of humanity's lived experiences. Bioarchaeological interpretations of human health generally are made from datasets consisting of skeletal markers of stress, markers that result from (chronic) physiological disruption (e.g., porotic hyperostosis; linear enamel hypoplasia). Non-specific indicators of stress may measure episodes of stress and indicate that infection, disease, or nutritional deficiencies were present in a population, but in assessing these markers, bioarchaeologists are not measuring "health" in the same way as are human biologists, medical anthropologists, or primatologists. Rather than continue to diverge on separate (albeit parallel) trajectories, bioarchaeologists are advised to pursue interlinkages with other subfields within physical anthropology toward bridging "stress" and "health." The papers in this special symposium set include bioarchaeologists, human biologists, molecular anthropologists, and primatologists whose research develops this link between the concepts of "stress" and "health," encouraging new avenues for bioarchaeologists to consider and reconsider health in past human populations.
