    Papua New Guinea is a developing country with limited resources for specialist mental health services. Little is known about the mental health and treatment services of Papua New Guinea. The aim of this study was to clarify the presenting mental health problems encountered by Papua New Guinean health workers and the common treatment approaches used. A total of 203 Papua New Guinean health workers completed a retrospective quantitative survey about their three most recent mental health patients. The survey asked about presenting symptomatology, diagnoses (including culture-bound diagnoses) and treatment approaches. The major presenting mental health problems for males included schizophrenia, substance use disorder, sorcery and spirit possession. Depression was the most common diagnoses for women, followed by sorcery and somatisation. Over 65% of patients were prescribed psychotropic medication, over 50% received some form of psychological intervention and 28% were receiving traditional treatments. Somatic symptoms are common among both male and female Papua New Guineans; however, males may be more likely to present with psychotic symptoms and females with mood-related problems. Schizophrenia and depression are commonly identified with substance use disorder more problematic among males. Culture-specific explanations and treatment are commonly used. © The Author(s) 2013.

    Previous research suggests that cognitive functioning is associated with the risk of several adult psychiatric disorders. In this study we investigated whether adolescents who perform worse than expected at secondary school are at a higher risk for general mental health problems. In a cross-sectional survey comprising 10,866 Dutch adolescents aged 13 to 16 years, underachievement at secondary school was defined as the discrepancy between predicted school grade and actual grade 1 or 3 years later. Mental health problems were assessed using the Strengths and Difficulties Questionnaire. We investigated the association of underachievement with mental health problems using logistic regression, adjusting for potential confounders. Underachievement was associated with general psychopathology in pupils aged 13 to 14 years (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.47-2.37) and in pupils aged 15 to 16 years (OR, 2.05; 95% CI, 1.67-2.52) in a multivariate analysis including sociodemographic factors. The association between underachievement and mental health problems was attenuated when school factors such as teacher advice and interaction between underachievement and teacher advice were added, but underachievement remained significantly associated with mental health problems in adolescents in the higher educational tracks (pupils aged 13-14 years: OR, 2.22; 95% CI, 1.07-4.60 and OR, 2.41; 95% CI, 1.10-5.30, age 15-16 years: OR, 2.63; 95% CI, 1.38-5.03). In the multivariate analysis including the interaction between underachievement and teacher advice, a significant interaction effect occurs between underachievement and teacher advice in the higher tracks. Values of OR and CI are given for each significant interaction term. In the younger age group (pupils aged 13-14 years) this results in 2 sets of OR and CI. This association was most pronounced for the hyperactivity subscale of the Strengths and Difficulties Questionnaire. Underachievement at secondary school

    Background: Recognizing and appropriately treating mental health problems among new immigrants and refugees in primary care poses a challenge because of differences in language and culture and because of specific stressors associated with migration and resettlement. We aimed to identify risk factors and strategies in the approach to mental health assessment and to prevention and treatment of common mental health problems for immigrants in primary care. Methods: We searched and compiled literature on prevalence and risk factors for common mental health problems related to migration, the effect of cultural influences on health and illness, and clinical strategies to improve mental health care for immigrants and refugees. Publications were selected on the basis of relevance, use of recent data and quality in consultation with experts in immigrant and refugee mental health. Results: The migration trajectory can be divided into three components: premigration, migration and postmigration resettlement. Each phase is associated with specific risks and exposures. The prevalence of specific types of mental health problems is influenced by the nature of the migration experience, in terms of adversity experienced before, during and after resettlement. Specific challenges in migrant mental health include communication difficulties because of language and cultural differences; the effect of cultural shaping of symptoms and illness behaviour on diagnosis, coping and treatment; differences in family structure and process affecting adaptation, acculturation and intergenerational conflict; and aspects of acceptance by the receiving society that affect employment, social status and integration. These issues can be addressed through specific inquiry, the use of trained interpreters and culture brokers, meetings with families, and consultation with community organizations.

    High degrees of premature retirement among teachers warrant investigating the occupational burden and the mental health status of this profession. A sample of 1074 German teachers participated in this study. Two samples of the general population (N = 824 and N = 792) were used as comparison groups. Work distress was assessed with the Effort-Reward-Imbalance questionnaire, and mental health problems were measured with the General Health Questionnaire (GHQ-12). Teachers reported more effort-reward imbalance (M = 0.64) compared with the general population (M = 0.57), and they perceived more mental health problems (GHQ: M = 12.1) than the comparison group (M = 9.5). School type was not associated with work stress and mental health. Teachers with leading functions perceived high degrees of effort and reward, resulting in a moderate effort-reward ratio and no heightened mental health problems. Teachers working full time reported more effort than teachers working part time, but the reward mean values of both groups were similar. This results in a somewhat unfavourable effort-reward ratio of teachers working full time. Moreover, teachers working full time reported more mental health problems. The results support the appropriateness of the effort-reward conception, applied to the profession of teachers. The higher degree of effort-reward imbalance and the level of mental health problems warrant preventive measures. Copyright © 2014 John Wiley & Sons, Ltd. Copyright © 2014 John Wiley & Sons, Ltd.

    Full Text Available BACKGROUND: Satisfaction is widely used to evaluate and direct delivery of medical care; a complicated relationship exists between patient satisfaction, morbidity and age. This study investigates the relationships between complexity of health problems and level of patient satisfaction of older persons with their general practitioner (GP and practice. METHODS AND FINDINGS: This study is embedded in the ISCOPE (Integrated Systematic Care for Older Persons study. Enlisted patients aged ≥75 years from 59 practices received a written questionnaire to screen for complex health problems (somatic, functional, psychological and social. For 2664 randomly chosen respondents (median age 82 years; 68% female information was collected on level of satisfaction (satisfied, neutral, dissatisfied with their GP and general practice, and demographic and clinical characteristics including complexity of health problems. Of all participants, 4% was dissatisfied with their GP care, 59% neutral and 37% satisfied. Between these three categories no differences were observed in age, gender, country of birth or education level. The percentage of participants dissatisfied with their GP care increased from 0.4% in those with 0 problem domains to 8% in those with 4 domains, i.e. having complex health problems (p<0.001. Per additional health domain with problems, the risk of being dissatisfied increased 1.7 times (95% CI 1.4-2.14; p<0.001. This was independent of age, gender, and demographic and clinical parameters (adjusted OR 1.4, 95% CI 1.1-1.8; p = 0.021. CONCLUSION: In older persons, dissatisfaction with general practice is strongly correlated with rising complexity of health problems, independent of age, demographic and clinical parameters. It remains unclear whether complexity of health problems is a patient characteristic influencing the perception of care, or whether the care is unable to handle the demands of these patients. Prospective studies are needed to

    To investigate the relieving effects of hot spring balneotherapy on mental stress, sleep disorder, general health problems, and women's health problems in sub-healthy people, we recruited 500 volunteers in sub-health in Chongqing, and 362 volunteers completed the project, including 223 in the intervention group and 139 in the control group. The intervention group underwent hot spring balneotherapy for 5 months, while the control group did not. The two groups took questionnaire investigation (general data, mental stress, emotional status, sleep quality, general health problems, as well as some women's health problems) and physical examination (height, weight, waist circumference, blood pressure, blood lipid, blood sugar) 5 months before and after the intervention, respectively. After intervention, sleep disorder (difficulty in falling asleep ( P = 0.017); dreaminess, nightmare suffering, and restless sleep ( P = 0.013); easy awakening ( P = 0.003) and difficulty in falling into sleep again after awakening( P = 0.016); and mental stress ( P = 0.031) and problems of general health (head pain ( P = 0.026), joint pain( P = 0.009), leg or foot cramps ( P = 0.001), blurred vision ( P = 0.009)) were relieved significantly in the intervention group, as compared with the control group. While other indicators (fatigue, eye tiredness, limb numbness, constipation, skin allergy) and women's health problems (breast distending pain; dysmenorrhea, irregular menstruation) were relieved significantly in the self-comparison of the intervention group before and after intervention ( P 0.05). All indications (except bad mood, low mood, and worry or irritability) in the intervention group significantly improved, with effect size from 0.096 to 1.302. Multiple logistic regression analysis showed that the frequency, length, and location of balneotherapy in the intervention group were the factors influencing emotion, sleep, and health condition ( P Physical examination found that waist

    Refugees are a particularly vulnerable group in relation to the development of mental illness and many may have been subjected to torture or other traumatic experiences. General practitioners are gatekeepers for access to several parts of the psychiatric system and knowledge of their patients' refugee background is crucial to secure adequate care. The aim of this study is to investigate how general practitioners experience providing care to refugees with mental health problems. The study was conducted as part of an EU project on European Best Practices in Access, Quality and Appropriateness of Health Services for Immigrants in Europe (EUGATE). Semi-structured interviews were carried out with nine general practitioners in the vicinity of Copenhagen purposively selected from areas with a high proportion of immigrants. The analysis of the interviews is inspired by qualitative content analysis. One of the main themes identified in the analysis is communication. This includes the use of professional interpreters and that communication entails more than sharing a common language. Quality of care is another theme that emerges and includes awareness of possible trauma history, limited possibilities for refugees to participate in certain treatments due to language barriers and feelings of hopelessness in the general practitioners. The general practitioners may also choose different referral pathways for refugees and they report that their patients lack understanding regarding the differences between psychological problems and physical symptoms. General practitioners experience that providing care to refugees differs from providing care for patients from the majority population. The different strategies employed by the general practitioners in the health care treatment of refugees may be the result of the great diversity in the organisation of general practice in Denmark and the lack of a national strategy in the health care management of refugees.

    1992-08-08

    The aim of this study was to determine whether the austerely living Trappist and Benedictine monks have a lower prevalence of a number of risk factors and health problems than the general Dutch population. A written questionnaire was submitted to monks of 7 monasteries. The response was 67 per cent (134 monks). The data were compared with data from the national Health Interview Survey of 1989, which used an almost identical questionnaire. Adjustment was made for differences in age and education. Monks consume less alcohol and tobacco and have a more austere diet. Their average Quetelet index is lower. The prevalence of cardiovascular disease is lower. On the other hand, monks more often report a number of other chronic diseases, physical complaints, and problems with activities of daily life. They more often have contact with general practitioners and with consultants. The lower prevalence of a number of risk factors among monks reflects their austere way of life. It is not certain whether the lower prevalence of cardiovascular diseases can be attributed to this way of life. The fact that, in general, health problems are more prevalent among monks suggests that changes in lifestyle do not necessarily lead to compression of morbidity.

    Population exposure in excess of that due to natural radiation background is known to result primarily (to 70-90%) from medical X-rays given in mass screening. Protection of the population is a problem of great concern in present-day radiology and is approached by balancing benefits of diagnostic X-rays against risks presented by the probability of overexposing the patient. An evaluation on such a basis necessitates detailed and accurate information on patient radiation exposure and takes into account factors leading to a population hazard by making assessments in terms of so-called genetically significant doses. Gonad doses have to be carefully analysed, implying a need for studies of various types of X-ray procedures, precautionary measures taken, etc. An important issue in the choice and adoption of an appropriate method for large-scale gonad dose assessments in routine practice. To obtain an estimate of radiation hazard from medical roentgenology in terms of genetically significant doses and identify measures necessary to limit exposure risks, collaborative efforts are needed involving participation of roentgenologists and hygienists, and use of dosimetric, organizational-methodological, and statistical techniques. These efforts should lead to an abrupt reduction in radiation burden to the population from diagnostic X-rays. (author)

    This study aimed to detect striking trends based on a new strategy for monitoring public health. We used data over 4 years from electronic medical records of a large, nationally representative network of general practices. Episodes were either directly recorded by general practitioners (GPs) or were constructed using a new record linkage method (EPICON). The episodes were used to estimate raw morbidity rates for all codes of the International Classification of Primary Care (ICPC). Multilevel Poisson regression models were used to analyse the trend over time for 15 health problems that showed an obvious change over time. Based on these models, we calculated adjusted incidence rates corrected for clustering, sex and age. During 2002-05, both men and women increasingly consulted the GP because of concern about a drug reaction, a change in faeces/bowel movements and urination problems. Men showed an increase in consultations for prostate problems and venereal diseases. The incidence of chronic internal knee derangement decreased for both sexes. Women consulted their GP less frequently about sterilization and fear of being pregnant. The strategy developed proved to be useful to detect trends across a short period of time. Changes in the health care market, such as the increasing availability of over-the-counter drugs and various large advertising campaigns for medications may explain some of the findings. The increasing incidence of health problems in the urogenital area deserves attention as it could reflect increases in the incidence of sexually transmitted diseases (STDs) and urinary tract infections.

    To explore the experiences of family carers of people with cognitive impairment during admission to hospital. Providing appropriate care in acute hospitals for people with co-morbid cognitive impairment, especially dementia or delirium or both, is challenging to healthcare professionals. One key element is close working with family members. Qualitative interview study. Semi-structured interviews with family carers of 34 older people who had been admitted to a UK general hospital and had co-morbid cognitive impairment. Interviews conducted in 2009 and 2010. Analysis was undertaken using Strauss and Corbin's framework. The findings elaborate a core problem, 'disruption from normal routine' and a core process, 'gaining or giving a sense of control to cope with disruption'. Family carers responded to disruption proactively by trying to make sense of the situation and attempting to gain control for themselves or the patient. They tried to stay informed, communicate with staff about the patient and plan for the future. The interaction of the core problem and the core process resulted in outcomes where family members either valued the support of hospital staff and services or were highly critical of the care provided. Family carers are not passive in the face of the disruption of hospitalization and respond both by trying to involve themselves in the care and support of their relative and by trying to work in partnership with members of staff. Nurses need to foster this relationship conscientiously. © 2013 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The objective was to review all available literature concerning Type D (distressed personality among the general population and to discuss its implications for research on health status, disease-promoting mechanisms and work-related problems in non-clinical populations. Methods A computerized search of the literature was performed independently and in duplicate by both investigators on December 21st, 2009. Published research reports were included if they studied Type D personality among the general population. Nineteen articles were selected and they were subjected to an 11-item standardised quality checklist by both investigators. Results The methodological quality of the selected studies was adequate to high. The studies included in this review showed that the presence of Type D characteristics had a negative impact on mental health status (more symptoms of depression, anxiety, post-traumatic stress disorder, mental distress, passive coping, and less social support and physical health status (more somatic complaints, lower health status, more influenza-like illness reporting. Other studies reported on behavioral and biological mechanisms of disease in apparently healthy individuals with a Type D personality. Finally, some studies also showed a negative effect of Type D personality on work-related problems (higher absence-leave, higher levels of vital exhaustion and burnout, and more work-related stress. Conclusions Type D personality is a vulnerability factor for general psychological distress that affects mental and physical health status and is associated with disease-promoting mechanisms and work-related problems in apparently healthy individuals.

    Carey, Hollis L.; Andrews, Carroll B.

    1949-01-01

    Medical care for rural populations is an important problem facing the medical profession nationally and locally. The mechanism for solution lies in the existing American Medical Association and California Medical Association committees on rural medical service and further development of “local health councils.” Additional emphasis on training of physicians for general practice is essential through medical school graduate and postgraduate periods. The problem of providing additional adequately equipped and staffed hospitals must receive much consideration. Recognizing that passiveness invites aggressive non-medical agencies to foster bureaucratic dictation inimical to the practice of medicine, the rural physician must act through medical and community organizations to correct weaknesses in the structure of medical practice.

    The 'Research Agenda for General Practice/Family Medicine and Primary Health Care in Europe' summarizes the evidence relating to the core competencies and characteristics of the Wonca Europe definition of GP/FM, and its implications for general practitioners/family doctors, researchers and policy makers. The European Journal of General Practice publishes a series of articles based on this document. The previous articles presented background, objectives, and methodology, as well results on 'primary care management' and 'community orientation' and the person-related core competencies of GP/FM. This article reflects on the general practitioner's 'specific problem solving skills'. These include decision making on diagnosis and therapy of specific diseases, accounting for the properties of primary care, but also research questions related to quality management and resource use, shared decision making, or professional education and development. Clinical research covers most specific diseases, but often lacks pragmatism and primary care relevance. Quality management is a stronghold of GP/FM research. Educational interventions can be effective when well designed for a specific setting and situation. However, their message that 'usual care' by general practitioners is insufficient may be problematic. GP and their patients need more research into diagnostic reasoning with a step-wise approach to increase predictive values in a setting characterized by uncertainty and low prevalence of specific diseases. Pragmatic comparative effectiveness studies of new and established drugs or non-pharmaceutical therapy are needed. Multi-morbidity and complexity should be addressed. Studies on therapy, communication strategies and educational interventions should consider impact on health and sustainability of effects.

  17. Dimensional reduction of a generalized flux problem

    Moroz, A.

    1992-01-01

    In this paper, a generalized flux problem with Abelian and non-Abelian fluxes is considered. In the Abelian case we shall show that the generalized flux problem for tight-binding models of noninteracting electrons on either 2n- or (2n + 1)-dimensional lattice can always be reduced to an n-dimensional hopping problem. A residual freedom in this reduction enables one to identify equivalence classes of hopping Hamiltonians which have the same spectrum. In the non-Abelian case, the reduction is not possible in general unless the flux tensor factorizes into an Abelian one times are element of the corresponding algebra

    Iraq is faced with large scale public health problems that have been caused by the destruction to their infrastructure during the Gulf war. Humanitarian aid is needed in order to avoid a large scale human disaster. In 1988 73% of Iraq's population lived in urban areas. The loss of electrical generating capacity has affected hospitals, water purification and sewage treatment. Iraq had made great strides int he health of their people with an infant mortality rate of 42/1000 in 1990 and 52./1000 for children under 5. The international study team's survey of over 9000 households revealed surprising evidence of widespread chronic malnutrition. Based on accepted mortality as a baseline, data suggests that mortality among Iraqi infants and children under 5 doubled in 1991. The current food ration provides only half of the energy requirement and with rapidly accelerating inflation, the cost of food while only make the situation worse. The UN Disaster Relief Office has received $1.059 billion from donor countries; but, only half of the requested $14 million has been funded through Unicef. This money is needed to meet basic requirements for water, sanitation, antibiotics, and vaccines. The UN Security Council approved resolutions 706 and 712 which would have allowed Iraq to sell $1.6 billion for foodstuffs, medicines, and materials and supplies necessary to civilian needs subject to monitoring and supervision to ensure equitable distribution. The Iraqi government has not met the requirements of 706 and 712 because of the monitoring conditions, so no money has been issued. More money is needed if humanitarian organizations are to do their work. Only $29 million of the $145 million needed for the 1st half of this year has been pledged.

  19. Algorithm for the Stochastic Generalized Transportation Problem

    2012-01-01

    Full Text Available The equalization method for the stochastic generalized transportation problem has been presented. The algorithm allows us to find the optimal solution to the problem of minimizing the expected total cost in the generalized transportation problem with random demand. After a short introduction and literature review, the algorithm is presented. It is a version of the method proposed by the author for the nonlinear generalized transportation problem. It is shown that this version of the method generates a sequence of solutions convergent to the KKT point. This guarantees the global optimality of the obtained solution, as the expected cost functions are convex and twice differentiable. The computational experiments performed for test problems of reasonable size show that the method is fast. (original abstract

    Full Text Available Introduction:Today, shift work is considered as a necessity in many jobs and for some 24-hour services the use of shift-work is growing. However, shift work can lead to physiological and psycho-social problems for shift workers. This study aimed to determine the effects of shift work on the associated health problems, together with the demographic and job characteristics underlying the problems, among the medical and diagnostic staff of the general teaching hospitals affiliated to Shiraz University of Medical Sciences in 2012. Method:This study was an applied, cross-sectional and descriptive-analytical one. The study employed a sample of 205 employees from the medical and diagnostic staff using stratified sampling proportional to the size and simple random sampling methods. Data were collected using the Survey of Shift workers (SOS questionnaire, validity and reliability of which have already been confirmed. Finally, the collected data were analyzed using SPSS 16.0 software through ANOVA, Chi-square, Independent-Samples T-Test, as well as Pearson Correlation Coefficient. A P<0.05 was considered statistically significant. Results: The results showed that among the demographic and job characteristics studied, the individual, family and social problems had significant associations with work schedules, shift work and job satisfaction. In addition, there were significant associations between musculoskeletal disorders and the satisfaction of shift work; cardiovascular disorders and marital status and occupation; digestive disorders and the work schedules; sleep disorders and the satisfaction of shift work; musculoskeletal disorders, cardiovascular disorders and sleep disorders and age, job experience and shift work experience. And finally, there were significant associations among sleep disorders and age, job experience and the shift work experience.

    Problem solving therapy (PST) is one of the focused psychological strategies supported by Medicare for use by appropriately trained general practitioners. This article reviews the evidence base for PST and its use in the general practice setting. Problem solving therapy involves patients learning or reactivating problem solving skills. These skills can then be applied to specific life problems associated with psychological and somatic symptoms. Problem solving therapy is suitable for use in general practice for patients experiencing common mental health conditions and has been shown to be as effective in the treatment of depression as antidepressants. Problem solving therapy involves a series of sequential stages. The clinician assists the patient to develop new empowering skills, and then supports them to work through the stages of therapy to determine and implement the solution selected by the patient. Many experienced GPs will identify their own existing problem solving skills. Learning about PST may involve refining and focusing these skills.

    This paper aimed to measure the prevalence and outcomes of delirium for patients over 70 admitted to a general hospital for acute medical care and to assess the validity of the Delirium Rating Scale-Revised-98 (DRS-R-98) in this setting. Prospective study in a British acute general hospital providing sole emergency medical services for its locality. We screened consecutive patients over 70 with an unplanned emergency hospital admission and recruited a cohort of 249 patients likely to have mental health problems. They were assessed for health status at baseline and followed over 6 months. A sub-sample of 93 participants was assessed clinically for delirium. 27% (95% confidence interval (CI) 23-31) of all older medical patients admitted to hospital had DRS-diagnosed delirium, and 41% (95% CI 37-45) had dementia (including 19% with co-morbid delirium and dementia). Compared with clinician diagnosis, DRS-R-98 sensitivity was at least 0.75, specificity 0.71. Compared with reversible cognitive impairment, sensitivity was at least 0.50, specificity 0.67. DRS-diagnosed delirium was associated with cognitive impairment, mood, behavioural and psychological symptoms, activities of daily living, and number of drugs prescribed, supporting construct validity. Of those with DRS-diagnosed delirium, 37% died within 6 months (relative risk 1.4, 95% CI 0.97-2.2), 43% had reversible cognitive impairment, but only 25% had clinically important recovery in activities of daily living. Behavioural and psychological symptoms were common and mostly resolved, but new symptoms frequently developed. Delirium is common. Some, but not all, features are reversible. DRS-R-98 has reasonable validity in populations where co-morbid dementia is prevalent. Copyright © 2013 John Wiley & Sons, Ltd.

    Full Text Available We welcome Andrew Haig's critique of our paper, "Disability & Health: A research agenda" in Social Inclusion. Our paper sought to identify research priorities to better understand, provide enhanced services and a better quality of life for people with disabilities, particularly in relation to their health and wellbeing. Haig's critique makes several important points that deserve serious consideration. His comments reflect a view of the relationship between disability and health which is different from the one we have espoused. Specifically, Haig argues that (a disability is a health problem, (b medical rehabilitation should be separated from Community Based Rehabilitation (CBR, and (c the evidence base for medical rehabilitation is much stronger than for CBR. We address each of these points below arguing that while some types of disability clearly result from health problems; often disability is not experienced as a health problem; and sometimes, disability in interaction with restricted access is the cause of health problems.

    Dias, Ulisses; Galvão, Gustavo Rodrigues; Lintzmayer, Carla Négri; Dias, Zanoni

    2014-06-01

    In this paper, we present a general heuristic for several problems in the genome rearrangement field. Our heuristic does not solve any problem directly, it is rather used to improve the solutions provided by any non-optimal algorithm that solve them. Therefore, we have implemented several algorithms described in the literature and several algorithms developed by ourselves. As a whole, we implemented 23 algorithms for 9 well known problems in the genome rearrangement field. A total of 13 algorithms were implemented for problems that use the notions of prefix and suffix operations. In addition, we worked on 5 algorithms for the classic problem of sorting by transposition and we conclude the experiments by presenting results for 3 approximation algorithms for the sorting by reversals and transpositions problem and 2 approximation algorithms for the sorting by reversals problem. Another algorithm with better approximation ratio can be found for the last genome rearrangement problem, but it is purely theoretical with no practical implementation. The algorithms we implemented in addition to our heuristic lead to the best practical results in each case. In particular, we were able to improve results on the sorting by transpositions problem, which is a very special case because many efforts have been made to generate algorithms with good results in practice and some of these algorithms provide results that equal the optimum solutions in many cases. Our source codes and benchmarks are freely available upon request from the authors so that it will be easier to compare new approaches against our results.

    Full Text Available Mentally disabled individuals are at risk of health problems. In fact, health problems are more frequent in mentally disabled individuals than in the general population and mentally disabled individuals less frequently use health care facilities. It has been shown that mentally disabled individuals frequently have nutritional problems. They may suffer from low weight, malnutrition, high weight, pica, iron and zinc deficiencies and absorption and eating disorders. Activities can be limited due to motor disability and restricted movements. Depending on insufficient liquid intake and dietary fiber, constipation can be frequent. Another problem is sleep disorders such as irregular sleep hours, short sleep, waking up at night and daytime sleepiness. Visual-hearing losses, epilepsy, motor disability, hepatitis A infection and poor oral hygiene are more frequent in mentally disabled children than in the general population. The mentally disabled have limited health care facilities, poorer health status than the general population and difficulties in demanding for health care and expressing health problems. Therefore, they should be provided with more health promotion services. [TAF Prev Med Bull 2010; 9(2.000: 145-150

    2012-01-01

    We consider the following geometric alignment problem: Given a set of line segments in the plane, find a convex region of smallest area that contains a translate of each input segment. This can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be turned through 360 degrees within this region. Our main result is an optimal Θ(n log n)-time algorithm for our geometric alignment problem, when the input is a set of n line segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then the optimum placement is when the midpoints of the segments coincide.

    Harrison, Glenn W.; Jessen, Lasse J.; Lau, Morten

    We compare several popular survey instruments for measuring gambling behavior and gambling propensity to assess if they differ in their classification of individuals in the general adult Danish population. We also examine correlations with standard survey instruments for alcohol use, anxiety......, depression and impulsivity. A feature of our design is that nobody was excluded on the basis of their response to a “trigger,” “gateway” or “diagnostic item” question about previous gambling history. Our sample consists of 8,405 adult Danes. We administered the Focal Adult Gambling Screen to all subjects...... and estimate prevalence of gambling problems using sample weights and controlling for sample selection. We find that 95.4% of the population has no detectable risk, 2.9% has an early risk, 0.8% has an intermediate risk, 0.7% has an advanced risk, and 0.2% can be classified as problem gamblers...

    The Lie derivative approach to the Cauchy problem in general relativity is applied to the evolution along an arbitrary timelike vector field for the case where the dynamical degrees of freedom are chosen as the (generally anholonomic) metric of the hypersurface elements orthogonal to the vector field. Generalizations of the shear, rotation, and acceleration are given for a nonunit timelike vector field, and applied to the three-plus-one breakup of the Riemann tensor into components parallel and orthogonal to the vector field, resulting in the anholonomic Gauss--Codazzi equations. A similar breakup of the Einstein field equations results in the form of the constraint and evolution equations for the anholonomic case. The results are applied to the case of a space--time with a timelike Killing vector field (stationary field) to demonstrate their utility. Other possible applications, such as in the numerical integration of the field equations, are mentioned. Definitions are given of three-index shear, rotation, and acceleration tensors, and their use in a two-plus-two decomposition of the Riemann tensor and field equations is indicated

    Full Text Available Background: The purpose of this study was to investigate the relation of optimism with mental health and the affectivity of optimism training on mental health and its components on Yazd University students. Materials and Methods: Fifty new students of the 2008-2009 academic years were randomly selected. The General Health Questionnaire (GHQ-28 and the optimism scale were completed by them. Thirty persons of these students, who had the highest psychological problems based on the general health questionnaire, were divided into two case and control groups through random assignment. The case group was trained for one month, in two 90-minute sessions per week. Pre-tests and follow-up tests were performed in both groups.Results: The results of Pearson correlation coefficients showed that optimism had a negative and significant relationship with mental health, anxiety, social function, and depression scores (p0.005. Multivariate analysis of covariance showed that optimism training had significant impact on mental health and its components in the case group, compared with the control group (p< 0.0001.Conclusion: In general, the findings of this research suggest the relationship between optimism and mental health and the effectiveness of optimism training on mental health. This method can be used to treat and prevent mental health problems.

    Increased intra-subject reaction time variability (RT-ISV) as coarsely measured by the standard deviation (RT-SD) has been associated with many forms of psychopathology. Low-frequency RT fluctuations, which have been associated with intrinsic brain rhythms occurring approximately every 15-40s, have been shown to add unique information for ADHD. In this study, we investigated whether these fluctuations also relate to attentional problems in the general population, and contribute to the two major domains of psychopathology: externalizing and internalizing problems. RT was monitored throughout a self-paced sustained attention task (duration: 9.1 ± 1.2 min) in a Dutch population cohort of young adults (n=1455, mean age: 19.0 ± 0.6 years, 55.1% girls). To characterize temporal fluctuations in RT, we performed direct Fourier Transform on externally validated frequency bands based on frequency ranges of neuronal oscillations: Slow-5 (0.010-0.027 Hz), Slow-4 (0.027-0.073 Hz), and three additional higher frequency bands. Relative magnitude of Slow-4 fluctuations was the primary predictor in regression models for attentional, internalizing and externalizing problems (measured by the Adult Self-Report questionnaire). Additionally, stepwise regression models were created to investigate (a) whether Slow-4 significantly improved the prediction of problem behaviors beyond the RT-SD and (b) whether the other frequency bands provided important additional information. The magnitude of Slow-4 fluctuations significantly predicted attentional and externalizing problems and even improved model fit after modeling RT-SD first (R(2) change=0.6%, Pfrequency bands provided additional information. Low-frequency RT fluctuations have added predictive value for attentional and externalizing, but not internalizing problems beyond global differences in variability. This study extends previous findings in clinical samples of children with ADHD to adolescents from the general population and

    To investigate the effectiveness of psychological therapy in reducing psychological distress for adults with autism spectrum conditions (ASC) and co-morbid mental health conditions in routine clinical practice. To explore the effect of individual characteristics and service factors on change in general distress. In a specialist psychological therapies service for adults with ASC, the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) self-report questionnaire of psychological distress is completed by clients at start and end of therapy. Change over time and reliable and clinical change was assessed for 81 of a total of 122 clients (66.4%). Factors which may influence change over time were explored using available clinical information. Overall, there was a significant reduction in CORE-OM score during therapy with a small effect size. Most clients showed an improvement in psychological distress over therapy (75.4% improved, with 36.9% of these showing reliable changes). Significant and comparable reductions from pre-therapy to post-therapy were seen across the sample, showing that individual differences did not mediate therapy effectiveness. CORE-OM scores mediate the association between age of ASD diagnosis and hours of therapeutic input required, with greater age at diagnosis and higher distress associated with longer therapy duration. Our preliminary findings suggest that psychological therapy may be effective in reducing general distress for clients with ASC and co-morbid mental health conditions and should be routinely offered. Individuals who are diagnosed with ASD in adulthood are likely to require a longer course of therapy when their general distress scores are high. Copyright © 2017 John Wiley & Sons, Ltd.

    Given a set of line segments in the plane, not necessarily finite, what is a convex region of smallest area that contains a translate of each input segment? This question can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be rotated through 360 degrees within this region. We show that there is always an optimal region that is a triangle, and we give an optimal Θ(nlogn)-time algorithm to compute such a triangle for a given set of n segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then placing the segments with their midpoint at the origin and taking their convex hull results in an optimal solution. Finally, we show that for any compact convex figure G, the smallest enclosing disk of G is a smallest-perimeter region containing a translate of every rotated copy of G. © 2013 Springer Science+Business Media New York.

    Full Text Available Background : "Crime" is increasing day by day in our society not only in India but also all over the world. In turn, the number of prisoners is also increasing at the same rate. They remain imprisoned for a long duration or in some cases for the whole life. Living in a prison for long time becomes difficult for all inmates. So they often face adjustment and mental health problems. Recent findings suggest that mental illness rate in prison is three times higher than in the general population. Objective: The aim of the present study was to investigate the adjustment and the mental health problem and its relation in the prisoners. Materials and Methods : In the present study, 37 male prisoners of district jail of Dhanbad District of Jharkhand were selected on purposive sampling basis. Each prisoner was given specially designed Performa - Personal Data Sheet, General Health Questionnaire-12 and Bell Adjustment Inventory. Appropriate statistical tools were used to analyze the data. Results: The results obtained showed poor adjustment in social and emotional areas on the adjustment scale. The study also revealed a significant association between adjustment and mental health problem in the prisoners. Conclusion: The prisoners were found to have poor social and emotional adjustment which has strong association with their mental health.

    Alcohol has long been an integral part of the social life of many Australians. However, alcohol is associated with significant harm to drinkers, and also to nondrinkers. This article explores the role of the general practitioner in the detection and assessment of problem drinking. Excessive alcohol use is a major public health problem and the majority of people who drink excessively go undetected. General practitioners are in a good position to detect excessive alcohol consumption; earlier intervention can help improve outcomes. AUDIT-C is an effective screening tool for the detection of problem drinking. National Health and Medical Research Council guidelines suggest that no more than two standard drinks on each occasion will keep lifetime risk of death from alcohol related disease or injury at a low level. Once an alcohol problem is detected it is important to assess for alcohol dependence, other substance use, motivation to change, psychiatric comorbidities and examination and investigation findings that may be associated with excessive alcohol use. A comprehensive assessment of the impact and risk of harm of the patient's drinking to themselves and others is vital, and may require several consultations.

    Cognitive load theory was used to hypothesize that a general problem-solving strategy based on a make-as-many-moves-as-possible heuristic could facilitate problem solutions for transfer problems. In four experiments, school students were required to learn about a topic through practice with a general problem-solving strategy, through a conventional problem solving strategy or by studying worked examples. In Experiments 1 and 2 using junior high school students learning geometry, low knowledge students in the general problem-solving group scored significantly higher on near or far transfer tests than the conventional problem-solving group. In Experiment 3, an advantage for a general problem-solving group over a group presented worked examples was obtained on far transfer tests using the same curriculum materials, again presented to junior high school students. No differences between conditions were found in Experiments 1, 2, or 3 using test problems similar to the acquisition problems. Experiment 4 used senior high school students studying economics and found the general problem-solving group scored significantly higher than the conventional problem-solving group on both similar and transfer tests. It was concluded that the general problem-solving strategy was helpful for novices, but not for students that had access to domain-specific knowledge.

    To describe medical management by the general practitioner (GP) and occupational physician (OP) of workers sick listed due to mental health problems, and to determine agreement in diagnosis, main cause of sickness absence and obstacles in return to work. A cohort of 555 employees being sick listed for 12 to 20 weeks due to mental health problems was recruited and followed for 1 year. These employees were interviewed about their mental health and contacts with GP, OP, other specialists and employer. In addition, the GP and/or the OP of 72 employees were interviewed about the medical diagnosis and management. Most employees sick listed for 12-20 weeks visited their GP and OP. According to the employees most interventions applied by the GP were medical interventions, such as referral of employees and prescription of medical drugs. Working conditions were seldom discussed by the GP and work-related interventions were never applied. Most interventions applied by the OP were work-related interventions and/or contact with the employer. The OP more often talked about working conditions and conflicts. According to the employees, the communication between GP and OP only took place in 8% of the cases. Agreement in the diagnosis, main cause of sickness absence, and obstacles in return to work reported by the GPs and OPs of the same employee was poor. In addition, similarity in reported diagnosis by GP and/or OP and the employees' scores on valid questionnaires on (mental) health was limited. The lack of communication and agreement by Dutch GPs and OPs in medical diagnosis and management of employees long-term sick listed due to mental health problems are indicators of sub-optimal medical treatment and return-to-work strategies.

    Cross-sectional studies demonstrate that exposure to bullying in the workplace is positively correlated with self-reported health problems. However, these studies do not provide a basis to draw conclusions on the extent to which bullying leads to increased health problems or whether health problems increase the risk of being bullied. To provide better indications of a causal relationship, knowledge from prospective studies on the association between bullying in the workplace and health outcomes is therefore summarised. We conducted a systematic literature review of original articles from central literature databases on longitudinal associations between bullying in the workplace and health. Average associations between bullying and health outcomes are calculated using meta-analysis. A consistent finding across the studies is that exposure to bullying is significantly positively related to mental health problems (OR =1.68; 95% KI 1.35-2.09) and somatic symptoms (OR = 1.77; 95% KI 1.41-2.22) over time. Mental health problems are also associated with subsequent exposure to bullying (OR = 1.74; 95% KI 1.44-2.12). Bullying is positively related to mental health problems and somatic symptoms. The association between mental health problems and subsequent bullying indicates a self-reinforcing process between mental health and bullying. The methodological quality of the studies that were conducted is relatively sound. However, based on the existing knowledge base there are no grounds for conclusions regarding an unambiguous causal relationship between bullying and health.

    Children of parents with mental health problems (CPM) have an increased risk for behavioral and psychological problems. This study investigated the age- and gender-specific course as well as predictors of mental health problems in CPM using the longitudinal data (baseline 1- and 2-year follow-ups) of a German general population sample from the BELLA study. Children and adolescents aged 11-17 years (at baseline) who had a parent with mental health problems (n = 325) were analyzed. The mental health problems of the children were assessed by the self-reported version of the strengths and difficulties questionnaire (SDQ). We used individual growth modeling to investigate the age- and gender-specific course, and the effects of risk as well as personal, familial and social protective factors on self-reported mental health problems in CPM. Additionally, data were examined differentiating internalizing and externalizing mental health problems in CPM. Results indicated that female compared to male CPM showed increasing mental health problems with increasing age. Mental health problems in CPM were associated with lower self-efficacy, worse family climate and less social competence over time. Internalizing problems were associated with lower self-efficacy, less social competence and more severe parental mental health problems. Externalizing problems were associated with lower self-efficacy, worse family climate and lower social competence. The main limitations of the study are the short time period (2 years) covered and the report of mental health problems by only one parent. Our findings should be considered in the development of treatment and prevention programs for mental health problems in CPM.

    Alcohol consumption is associated with several complications of both physical and mental health. Light or moderate alcohol consumption may have beneficial effects on physical or mental health but this effect is still controversial and research in the mental health field is relatively scarce. Our aim was to investigate the association between varying levels of alcohol consumption and the common mental disorders of depression and anxiety in a large international primary care sample. The sample consisted of 5438 primary care attenders from 14 countries who participated in the WHO Collaborative Study of Psychological Problems in General Health Care. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT) and the mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). Light to moderate alcohol consumption was associated with a lower prevalence of depression and generalized anxiety disorder compared to abstinence while excessive alcohol consumption was associated with a higher prevalence of depression. This non-linear association was not substantially affected after adjustment for a range of possible confounding variables, including the presence of chronic disease and the current physical status of participants and was evident in different drinking cultures. The study confirms that excessive drinking is associated with an increased prevalence of depression, but also raises the possibility that light/moderate drinking may be associated with a reduced prevalence of both depression and anxiety. Any causal interpretation of this association is difficult in the context of this cross-sectional study and further longitudinal studies are needed. Copyright © 2013 Elsevier Ireland Ltd.

  20. Numerical solution of pipe flow problems for generalized Newtonian fluids

    International Nuclear Information System (INIS)

    Samuelsson, K.

    1993-01-01

    In this work we study the stationary laminar flow of incompressible generalized Newtonian fluids in a pipe with constant arbitrary cross-section. The resulting nonlinear boundary value problems can be written in a variational formulation and solved using finite elements and the augmented Lagrangian method. The solution of the boundary value problem is obtained by finding a saddle point of the augmented Lagrangian. In the algorithm the nonlinear part of the equations is treated locally and the solution is obtained by iteration between this nonlinear problem and a global linear problem. For the solution of the linear problem we use the SSOR preconditioned conjugate gradient method. The approximating problem is solved on a sequence of adaptively refined grids. A scheme for adjusting the value of the crucial penalization parameter of the augmented Lagrangian is proposed. Applications to pipe flow and a problem from the theory of capacities are given.

    Early childbearing is increasing worldwide, in both the developed and the developing countries. In 1975, 13 million young women became mothers before their 18th birthday. Such early childbearing causes major health, economic, social, and demographic problems. The disadvantages are felt by the young women, their sexual partners, the babies born to these women, and society in general. Reasons why adolescents are engaging in earlier sexual activity and experiencing more early pregnancies are enumerated. The 1st Interhemispheric Conference on Adolescent Fertility, sponsored by the Agency for International Development and other involved organizations, was held in 1976. The Conference participants made recommendations concerned with the legal, educational, and social aspects of early childbearing. Many youth education programs have been established since the Conference. Research projects have been launched to study the social consequences of adolescent pregnancy. Many more family life education and family planning services must be offered. A significant hindrance to such developments is the reluctance of adults around the world to recognize and deal with the problem.

    2017-12-01

    This study aims to explore the interrelationship among maternal oxytocin (OT) responsiveness, maternal mental health, maternal parenting behavior, and mental health of children under a free-play interaction. 61 mother-child dyads were recruited for the study. Maternal mental health problem and parenting self-efficacy were measured using self-reported questionnaires. The mental health problems of children were also evaluated using a mother-reported questionnaire. Furthermore, salivary OT was collected before and after a standardized 10min free-play interaction. Parenting behaviors, including eye gaze and touch, were measured during the free-play interaction. Maternal OT responsiveness was significantly associated with less maternal mental health problem, touch frequency, and mental health problem of children but not with parenting self-efficacy. In the multivariate linear regression analysis that considers maternal OT responsiveness and maternal and children's mental health problems, maternal OT responsiveness was not associated with the mental health problems of children. This result suggested that maternal mental health problem played a mediational role between maternal OT responsiveness and the mental health problem of children. Results supported the assertion that maternal OT responsiveness contributed to the increased risk of maternal mental health problems and, subsequently, the risk of mental health problems of their children.

    1997-01-01

    This study reviews data from a poll conducted in three municipalities of Vojvodina on health and social problems of 60-year old and older people (n = 104). Poverty and illness are the main two problems aged people have to deal with, whereas exhaustion, pains, moving around with difficulty, poor vision, heart and breathing problems, as well as cardiovascular diseases and diseases of the musculoskeletal system are the most frequent health problems. Socializing is poor in the old age. Every third aged person visits nobody, while every fifth aged person is visited by nobody. About 3% of examinees describe their relationships with children as negative. That is why it is necessary to organize a health care of the aged which should maintain health and functional abilities into the old age with adequate social care of both closed and open type as long as possible.

    There is a paradigm shift happening for sepsis. Sepsis is no longer solely conceptualized as problem of individual patients treated in emergency departments and intensive care units but also as one that is addressed as public health issue with population- and systems-based solutions. We offer a conceptual framework for sepsis as a public health problem by adapting the traditional model of primary, secondary, and tertiary prevention.

    2008-10-01

    The aim of this work was to assess the association among oral health, general health, and quality of life (QoL). The Oral Health Impact Profile (OHIP-49) and the RAND-36 were distributed amongst 118 psychology freshmen. Additionally, two single items self-rated general health (SRGH) and self-rated oral health (SROH) - were administered. Kruskal-Wallis and Mann-Whitney U-tests were used to evaluate differences between SRGH and SROH categories, regarding OHIP subscale scores and RAND subscale scores. More than 75% of the subjects rated their oral and general health as good. Mean OHIP scores and RAND scores indicated a relatively good oral- and general health-related QoL respectively. The correlation between oral and general health was weak. Significant differences were found between SRGH categories regarding RAND subscale scores, except for the 'role emotional' and 'mental health' subscales. Significant differences were also found between SROH categories regarding OHIP subscale scores, except for the 'psychological disability' subscale. However, no significant differences were found between SRGH categories regarding OHIP subscale scores, or between SROH categories regarding RAND subscale scores. The findings suggest that oral health, general health, and QoL have different determinants. Furthermore, oral health and general health appear to be mostly unrelated in this seemingly healthy population. It is proposed that if no apparent disease is present, oral and general health must be regarded as separate constructs.

    To identify patient expectations of clinical decision-making at consultations with their general practitioners for distinct health problems and to determine the patient and general practitioner characteristics related to these expectations, with special focus on gender. We performed a multicenter cross-sectional study in 360 patients who were interviewed at home. Data on patients' sociodemographic, clinical characteristics and satisfaction were gathered. General practitioners supplied information on their gender and postgraduate training in family medicine. A questionnaire was used to collect data on patients' expectations that their general practitioner account of their opinion and on expectations of clinical decision making> at consultations with their general practitioner for five problems or hypothetical clinical scenarios (strong chest pain/cold with fever/abnormal discharge/depression or sadness/severe family problem). Patients were asked to indicate their preference that decisions on diagnosis and treatment be taken by: a) the general practitioner alone; b) the general practitioner, taking account of the patient's opinion; c) the patient, taking account of the general practitioner's opinion and d) the patient alone. A logistic regression was performed for clinical decision-making. The response rate was 90%. The mean age was 47.3 + or - 16.5 years and 51% were female. Patients' expectations that their general practitioner listen, explain and take account of their opinions were higher than their expectations of participating in decision-making, depending on the problem in question: 32% wished to participate in chest pain and 49% in family problems. Women had lower expectations of participating in depression and family problems. Patients with female general practitioners had higher expectations of participating in family problems and colds. Most patients wished to be listened to, informed and taken into account by their general practitioners and, to a lesser

    A set of generalized coherent states for the one-dimensional Coulomb problem in coordinate representation is constructed. At first, we obtain a mapping for proper transformation of the one-dimensional Coulomb problem into a nonrotating four-dimensional isotropic harmonic oscillator in the hyperspherical space, and the generalized coherent states for the one-dimensional Coulomb problem is then obtained in exact closed form. This exactly soluble model can provide an adequate means for a quantum coherency description of the Coulomb problem in one dimension, sample for coherent aspects of the exciton model in one-dimension example in high-temperature superconductivity, semiconductors, and polymers. Also, it can be useful for investigating the coherent scattering of the Coulomb particles in one dimension

    2015-09-01

    Full Text Available This paper presents the application of Neutrosophic Set Theory (NST in solving Generalized Assignment Problem (GAP. GAP has been solved earlier under fuzzy environment. NST is a generalization of the concept of classical set, fuzzy set, interval-valued fuzzy set, intuitionistic fuzzy set. Elements of Neutrosophic set are characterized by a truth-membership function, falsity and also indeterminacy which is a more realistic way of expressing the parameters in real life problem. Here the elements of the cost matrix for the GAP are considered as neutrosophic elements which have not been considered earlier by any other author. The problem has been solved by evaluating score function matrix and then solving it by Extremum Difference Method (EDM [1] to get the optimal assignment. The method has been demonstrated by a suitable numerical example.

    2014-01-01

    Full Text Available A polymorphic uncertain linear programming (PULP model is constructed to formulate a class of generalized production planning problems. In accordance with the practical environment, some factors such as the consumption of raw material, the limitation of resource and the demand of product are incorporated into the model as parameters of interval and fuzzy subsets, respectively. Based on the theory of fuzzy interval program and the modified possibility degree for the order of interval numbers, a deterministic equivalent formulation for this model is derived such that a robust solution for the uncertain optimization problem is obtained. Case study indicates that the constructed model and the proposed solution are useful to search for an optimal production plan for the polymorphic uncertain generalized production planning problems.

  2. Radon: A health problem and a communication problem

    Johnson, R.H.

    1992-01-01

    The US Environmental Protection Agency (USEPA) is making great efforts to alert the American public to the potential health risks of radon in homes. The news media have widely publicized radon as a problem; state and local governments are responding to public alarms; and hundreds of radon open-quotes expertsclose quotes are now offering radon detection and mitigation services. Apparently, USEPA's communication program is working, and the public is becoming increasingly concerned with radon. But are they concerned with radon as a open-quotes healthclose quotes problem in the way USEPA intended? The answer is yes, partly. More and more, however, the concerns are about home resale values. Many homebuyers are now deciding whether to buy on the basis of a single radon screening measurement, comparing it with USEPA's action guide of 4 pCi L -1 . They often conclude that 3.9 is OK, but 4.1 is not. Here is where the communication problems begin. The public largely misunderstands the significance of USEPA's guidelines and the meaning of screening measurements. Seldom does anyone inquire about the quality of the measurements, or the results of USEPA performance testing? Who asks about the uncertainty of lifetime exposure assessments based on a 1-hour, 1-day, 3-day, or even 30-day measurement? Who asks about the uncertainty of USEPA's risk estimates? Fortunately, an increasing number of radiation protection professions are asking such questions. They find that USEPA's risk projections are based on many assumptions which warrant further evaluation, particularly with regard to the combined risks of radon and cigarette-smoking. This is the next communication problem. What are these radiation professions doing to understand the bases for radon health-risk projections? Who is willing to communicate a balanced perspective to the public? Who is willing to communicate the uncertainty and conservatism in radon measurements and risk estimates?

The main purposes of this study were to investigate shift work-related health problems and their risk factors among workers of "12-hour shift" schedule.MethodsThis cross-sectional study was carried out at 8 petrochemical industries in Asalooyeh area. Study population consisted of 1203 workers including 549 shift worker (46% and 654 day worker (54%. Data on personal details, shift schedule and adverse effects of shift work werecollected by anonymous questionnaire. Statistical analyses were performed using SPSS, version 11.5. The level of significance was set at 5%.ResultsAlthough, the results showed that health problems among shift workers was more prevalent than day workers, but the differences were just significant in gastrointestinal and musculoskeletal disorders (p<0.05. Multiple linear regressions indicated that in addition to shift working, other variants such as long work hours, type of employment, second job, number of children and job title were associated with health problems.ConclusionPrevalence rates of gastrointestinal and musculoskeletal problems among shift workers were significantly higher than that of day workers. Although, working in shift system was the main significant factor associated with the reported problems, but other demographic andwork variables were also found to have association.

    2010-04-01

    Health disparities exist along lines of race/ethnicity and socioeconomic class in US society. I argue that we should work to eliminate these health disparities because their existence is a moral wrong that needs to be addressed. Health disparities are morally wrong because they exemplify historical injustices. Contractarian ethics, Kantian ethics, and utilitarian ethics all provide theoretical justification for viewing health disparities as a moral wrong, as do several ethical principles of primary importance in bioethics. The moral consequences of health disparities are also troubling and further support the claim that these disparities are a moral wrong. The Universal Declaration of Human Rights provides additional support that health disparities are a moral wrong, as does an analogy with the generally accepted duty to provide equal access to education. In this article, I also consider and respond to 3 objections to my thesis.

    2017-11-01

    Findings from prior research have consistently indicated significant associations between self-regulation and externalizing behaviors. Significant associations have also been reported between children's language skills and both externalizing behaviors and self-regulation. Few studies to date, however, have examined these relations longitudinally, simultaneously, or with respect to unique clusters of externalizing problems. The current study examined the influence of preschool self-regulation on general and specific externalizing behavior problems in early elementary school and whether these relations were independent of associations between language, self-regulation, and externalizing behaviors in a sample of 815 children (44% female). Additionally, given a general pattern of sex differences in the presentations of externalizing behavior problems, self-regulation, and language skills, sex differences for these associations were examined. Results indicated unique relations of preschool self-regulation and language with both general externalizing behavior problems and specific problems of inattention. In general, self-regulation was a stronger longitudinal correlate of externalizing behavior for boys than it was for girls, and language was a stronger longitudinal predictor of hyperactive/impulsive behavior for girls than it was for boys.

  12. An Enhanced Genetic Algorithm for the Generalized Traveling Salesman Problem

    H. Jafarzadeh

    2017-12-01

    Full Text Available The generalized traveling salesman problem (GTSP deals with finding the minimum-cost tour in a clustered set of cities. In this problem, the traveler is interested in finding the best path that goes through all clusters. As this problem is NP-hard, implementing a metaheuristic algorithm to solve the large scale problems is inevitable. The performance of these algorithms can be intensively promoted by other heuristic algorithms. In this study, a search method is developed that improves the quality of the solutions and competition time considerably in comparison with Genetic Algorithm. In the proposed algorithm, the genetic algorithms with the Nearest Neighbor Search (NNS are combined and a heuristic mutation operator is applied. According to the experimental results on a set of standard test problems with symmetric distances, the proposed algorithm finds the best solutions in most cases with the least computational time. The proposed algorithm is highly competitive with the published until now algorithms in both solution quality and running time.

    The Bangladesh Rural Advancement Committee conducted operational research in Bangladesh to examine postpartum health problems. Researchers conducted focus groups, indepth interviews, and observation. More than 40% of the postpartum women had a delivery-related health problem by 2 weeks after delivery. 52% had signs or symptoms of anemia. Body needs after pregnancy, lactation, and blood loss during delivery exacerbate the nutritional anemia common to Bangladeshi women. 17% of the postpartum women had signs of infections. More than 50% had severe malnutrition, worsened by food taboos during the postpartum period. 60% of infant deaths occur in the neonatal period. The mortality risk is elevated in low birth weight (LBW) infants. In this study, more than 50% of the newborns were LBW infants. Many Bangladeshi mothers discard the colostrum and begin breast feeding several days after delivery. 11% of the postpartum women had breast problem (e.g., cracked nipples). Women believed that susceptibility to evil spirits accounted for their being more vulnerable to health problems during the postpartum. They feared leaving the household. These findings show a need for home visits to provide valuable postpartum care.

    2007-02-01

    The present review addresses the perceived stigma associated with admitting a mental health problem and seeking help for that problem in the military. Evidence regarding the public stigma associated with mental disorders is reviewed, indicating that the public generally holds negative stereotypes toward individuals with psychological problems, leading to potential discrimination toward these individuals. The internalization of these negative beliefs results in self-stigma, leading to reduced self-esteem and motivation to seek help. Even if soldiers form an intention to seek help for their psychological difficulty, barriers to mental health care may prevent the soldier from receiving the help they need. An overall model is proposed to illustrate how the stigma associated with psychological problems can prevent soldiers getting needed help for psychological difficulties and proposed interventions for reducing stigma in a civilian context are considered for military personnel.

  16. A Generalized Cauchy Distribution Framework for Problems Requiring Robust Behavior

    2010-01-01

    Full Text Available Statistical modeling is at the heart of many engineering problems. The importance of statistical modeling emanates not only from the desire to accurately characterize stochastic events, but also from the fact that distributions are the central models utilized to derive sample processing theories and methods. The generalized Cauchy distribution (GCD family has a closed-form pdf expression across the whole family as well as algebraic tails, which makes it suitable for modeling many real-life impulsive processes. This paper develops a GCD theory-based approach that allows challenging problems to be formulated in a robust fashion. Notably, the proposed framework subsumes generalized Gaussian distribution (GGD family-based developments, thereby guaranteeing performance improvements over traditional GCD-based problem formulation techniques. This robust framework can be adapted to a variety of applications in signal processing. As examples, we formulate four practical applications under this framework: (1 filtering for power line communications, (2 estimation in sensor networks with noisy channels, (3 reconstruction methods for compressed sensing, and (4 fuzzy clustering.

  17. A General Solution Framework for Component-Commonality Problems

    2009-05-01

    Full Text Available Component commonality - the use of the same version of a component across multiple products - is being increasingly considered as a promising way to offer high external variety while retaining low internal variety in operations. However, increasing commonality has both positive and negative cost effects, so that optimization approaches are required to identify an optimal commonality level. As components influence to a greater or lesser extent nearly every process step along the supply chain, it is not surprising that a multitude of diverging commonality problems is being investigated in literature, each of which are developing a specific algorithm designed for the respective commonality problem being considered. The paper on hand aims at a general framework which is flexible and efficient enough to be applied to a wide range of commonality problems. Such a procedure based on a two-stage graph approach is presented and tested. Finally, flexibility of the procedure is shown by customizing the framework to account for different types of commonality problems.

    2009-01-01

    In recent years, more attention has been paid on artificial life researches. Artificial life(AL) is a research on regulating gene parameters of digital organisms under complicated problematic environments through natural selections and evolutions to achieve the final emergence of intelligence. Most recent studies focused on solving certain real problems by artificial life methods, yet without much address on the AL life basic mechanism. The real problems are often very complicated, and the proposed methods sometimes seem too simple to handle those problems. This study proposed a new approach in AL research, named "generalized artificial life structure(GALS)", in which the traditional "gene bits" in genetic algorithms is first replaced by "gene parameters", which could appear anywhere in GALS. A modeling procedure is taken to normalize the input data, and AL "tissue" is innovated to make AL more complex. GALS is anticipated to contribute significantly to the fitness of AL evolution. The formation of"tissue" begins with some different AL basic cells, and then tissue is produced by the casual selections of one or several of these cells. As a result, the gene parameters, represented by "tissues", could become highly diversified. This diversification should have obvious effects on improving gene fitness. This study took the innovative method of GALS in a stock forecasting problem under a carefully designed manipulating platform. And the researching results verify that the GALS is successful in improving the gene evolution fitness.

    Anderson, Edward

    2017-01-01

    This book is a treatise on time and on background independence in physics. It first considers how time is conceived of in each accepted paradigm of physics: Newtonian, special relativity, quantum mechanics (QM) and general relativity (GR). Substantial differences are moreover uncovered between what is meant by time in QM and in GR. These differences jointly source the Problem of Time: Nine interlinked facets which arise upon attempting concurrent treatment of the QM and GR paradigms, as is required in particular for a background independent theory of quantum gravity. A sizeable proportion of current quantum gravity programs - e.g. geometrodynamical and loop quantum gravity approaches to quantum GR, quantum cosmology, supergravity and M-theory - are background independent in this sense. This book's foundational topic is thus furthermore of practical relevance in the ongoing development of quantum gravity programs. This book shows moreover that eight of the nine facets of the Problem of Time already occur upon ...

    This study highlights the spectrum of general surgical problems necessitating admission on intellectually disabled adult patients. Problems encountered in the management and the ways to overcome various difficulties are highlighted. Prospective collection of data on 63 consecutive developmentally disabled adult patients admitted to the Department of General Surgery, Riyadh Medical Complex (RMC), Riyadh, Kingdom of Saudi Arabia for various indications from January 2000 through December 2004. Demographic details, clinical presentation, diagnostic modalities, associated physical and neurological disabilities, coexisting medical condition, treatment options, morbidity and mortality were analyzed. Various difficulties encountered during the management and mean to overcome these problems are addressed. Sixty-three patients accounted for 71 admissions. Mean age was 26.7 years with a male preponderance (4.25:1). Fifty-four patients were admitted for various emergency conditions. History of pica could be obtained in 33% of the cases. Twenty-seven patients were admitted for acute abdomen. Volvulus of the colon (22.2%) and pseudo-obstruction (18.5%) were the most common causes of acute abdomen. Twenty-one patients were admitted with upper gastrointestinal bleeding. Reflux esophagitis was the most common cause of bleeding (62%). Overall morbidity was 41% for emergency admissions and 22% for elective surgery. Hospital mortality was 21.4% for emergency surgery. There was no death in elective cases. Developmentally disabled patients comprise a special class of patients with peculiar management problems. The treating clinician should be aware of various unexpected conditions not found as frequently in the normal patient population. Apparent lack of pain does not exclude an acute emergency. Possible surgical condition should be suspected if there is vomiting, abdominal distension, fever, increased irritability of recent onset. Male gender and history of pica are added risk factors

    We investigate a generalization of the three-dimensional spring-pendulum system. The problem depends on two real parameters (k, a), where k is the Young modulus of the spring and a describes the nonlinearity of elastic forces. We show that this system is not integrable when k ≠ -a. We carefully investigated the case k = -a when the necessary condition for integrability given by the Morales-Ruiz-Ramis theory is satisfied. We discuss an application of the higher order variational equations for proving the non-integrability in this case

    2011-03-01

    Full Text Available Abstract Background Nepal is one of the largest suppliers of labour to countries where there is a demand for cheap and low skilled workers. In the recent years the Gulf countries have collectively become the main destinations for international migration. This paper aims to explore the health problems and accidents experienced by a sample of Nepalese migrant in three Gulf countries. Methods A cross-sectional survey was conducted among 408 Nepalese migrants who had at least one period of work experience of at least six months in any of three Gulf countries: Qatar, Saudi Arabia and United Arab Emirates (UAE. Face to face questionnaire interviews were conducted applying a convenience technique to select the study participants. Results Nepalese migrants in these Gulf countries were generally young men between 26-35 years of age. Unskilled construction jobs including labourer, scaffolder, plumber and carpenter were the most common jobs. Health problems were widespread and one quarter of study participants reported experiencing injuries or accidents at work within the last 12 months. The rates of health problems and accidents reported were very similar in the three countries. Only one third of the respondents were provided with insurance for health services by their employer. Lack of leave for illness, cost and fear of losing their job were the barriers to accessing health care services. The study found that construction and agricultural workers were more likely to experience accidents at their workplace and health problems than other workers. Conclusion The findings suggest important messages for the migration policy makers in Nepal. There is a lack of adequate information for the migrants making them aware of their health risks and rights in relation to health services in the destination countries and we suggest that the government of Nepal should be responsible for providing this information. Employers should provide orientation on possible health

    2011-03-01

    Obesity in the United States exacts a heavy health and financial toll, requiring new approaches to address this public health crisis. State attorneys general have been underutilized in efforts to formulate and implement food and obesity policy solutions. Their authority lies at the intersection of law and public policy, creating unique opportunities unavailable to other officials and government entities. Attorneys general have a broad range of authority over matters specifically relevant to obesity and nutrition policy, including parens patriae (parent of the country) authority, protecting consumer interests, enacting and supporting rules and regulations, working together across states, engaging in consumer education, and drafting opinions and amicus briefs. Significant room exists for greater attorney general involvement in formulating and championing solutions to public health problems such as obesity.

    ENGLISH ABSTRACT: The Multi-Objective Generalized Assignment Problem (MGAP with two objectives, where one objective is linear and the other one is non-linear, has been considered, with the constraints that a job is assigned to only one worker – though he may be assigned more than one job, depending upon the time available to him. An algorithm is proposed to find the set of Pareto optimal solutions of the problem, determining assignments of jobs to workers with two objectives without setting priorities for them. The two objectives are to minimise the total cost of the assignment and to reduce the time taken to complete all the jobs.

    Full Text Available Abstract Background Psychological problems present a huge burden of illness in our community and GPs are the main providers of care. There is evidence that longer consultations in general practice are associated with improved quality of care; but this needs to be balanced against the fact that doctor time is a limited resource and longer consultations may lead to reduced access to health care. The aim of this research was to conduct a systematic literature review to determine whether management of psychological problems in general practice is associated with an increased consultation length and to explore whether longer consultations are associated with better health outcomes for patients with psychological problems. Methods A search was conducted on Medline (Ovid databases up to7 June 2006. The following search terms, were used: general practice or primary health care (free text or family practice (MeSH AND consultation length or duration (free text or time factors (MeSH AND depression or psychological problems or depressed (free text. A similar search was done in Web of Science, Pubmed, Google Scholar, and Cochrane Library and no other papers were found. Studies were included if they contained data comparing consultation length and management or detection of psychological problems in a general practice or primary health care setting. The studies were read and categories developed to enable systematic data extraction and synthesis. Results 29 papers met the inclusion criteria. Consultations with a recorded diagnosis of a psychological problem were reported to be longer than those with no recorded psychological diagnosis. It is not clear if this is related to the extra time or the consultation style. GPs reported that time pressure is a major barrier to treating depression. There was some evidence that increased consultation length is associated with more accurate diagnosis of psychological problems. Conclusion Further research is needed to

    To estimate the frequency of psychological and social classification codes employed by general practitioners (GPs) and to explore the extent to which GPs ascribed health problems to biomedical, psychological, or social factors. A cross-sectional survey based on questionnaire data from GPs. Setting. Danish primary care. 387 GPs and their face-to-face contacts with 5543 patients. GPs registered consecutive patients on registration forms including reason for encounter, diagnostic classification of main problem, and a GP assessment of biomedical, psychological, and social factors' influence on the contact. The GP-stated reasons for encounter largely overlapped with their classification of the managed problem. Using the International Classification of Primary Care (ICPC-2-R), GPs classified 600 (11%) patients with psychological problems and 30 (0.5%) with social problems. Both codes for problems/complaints and specific disorders were used as the GP's diagnostic classification of the main problem. Two problems (depression and acute stress reaction/adjustment disorder) accounted for 51% of all psychological classifications made. GPs generally emphasized biomedical aspects of the contacts. Psychological aspects were given greater importance in follow-up consultations than in first-episode consultations, whereas social factors were rarely seen as essential to the consultation. Psychological problems are frequently seen and managed in primary care and most are classified within a few diagnostic categories. Social matters are rarely considered or classified.

    Full Text Available Abstract Objectives To address the relative importance of general job-related stressors, ambulance specific stressors and individual characteristics in relation to job satisfaction and health complaints (emotional exhaustion, psychological distress and musculoskeletal pain among ambulance personnel. Materials and methods A nationwide prospective questionnaire survey of ambulance personnel in operational duty at two time points (n = 1180 at baseline, T1 and n = 298 at one-year follow up, T2. The questionnaires included the Maslach Burnout Inventory, The Job Satisfaction Scale, Hopkins Symptom Checklist (SCL-10, Job Stress Survey, the Norwegian Ambulance Stress Survey and the Basic Character Inventory. Results Overall, 42 out of the possible 56 correlations between job stressors at T1 and job satisfaction and health complaints at T2 were statistically significant. Lower job satisfaction at T2 was predicted by frequency of lack of leader support and severity of challenging job tasks. Emotional exhaustion at T2 was predicted by neuroticism, frequency of lack of support from leader, time pressure, and physical demands. Adjusted for T1 levels, emotional exhaustion was predicted by neuroticism (beta = 0.15, p Psychological distress at T2 was predicted by neuroticism and lack of co-worker support. Adjusted for T1 levels, psychological distress was predicted by neuroticism (beta = 0.12, p Musculoskeletal pain at T2 was predicted by, higher age, neuroticism, lack of co-worker support and severity of physical demands. Adjusted for T1 levels, musculoskeletal pain was predicted neuroticism, and severity of physical demands (beta = 0.12, p Conclusions Low job satisfaction at T2 was predicted by general work-related stressors, whereas health complaints at T2 were predicted by both general work-related stressors and ambulance specific stressors.

  14. Origins and development of the Cauchy problem in general relativity

    2015-01-01

    The seminal work of Yvonne Choquet-Bruhat published in 1952 demonstrates that it is possible to formulate Einstein's equations as an initial value problem. The purpose of this article is to describe the background to and impact of this achievement, as well as the result itself. In some respects, the idea of viewing the field equations of general relativity as a system of evolution equations goes back to Einstein himself; in an argument justifying that gravitational waves propagate at the speed of light, Einstein used a special choice of coordinates to derive a system of wave equations for the linear perturbations on a Minkowski background. Over the following decades, Hilbert, de Donder, Lanczos, Darmois and many others worked to put Einstein's ideas on a more solid footing. In fact, the issue of local uniqueness (giving a rigorous justification for the statement that the speed of propagation of the gravitational field is bounded by that of light) was already settled in the 1930s by the work of Stellmacher. However, the first person to demonstrate both local existence and uniqueness in a setting in which the notion of finite speed of propagation makes sense was Yvonne Choquet-Bruhat. In this sense, her work lays the foundation for the formulation of Einstein's equations as an initial value problem. Following a description of the results of Choquet-Bruhat, we discuss the development of three research topics that have their origin in her work. The first one is local existence. One reason for addressing it is that it is at the heart of the original paper. Moreover, it is still an active and important research field, connected to the problem of characterizing the asymptotic behaviour of solutions that blow up in finite time. As a second topic, we turn to the questions of global uniqueness and strong cosmic censorship. These questions are of fundamental importance to anyone interested in justifying that the Cauchy problem makes sense globally. They are

  15. POWERPLAY: Training an Increasingly General Problem Solver by Continually Searching for the Simplest Still Unsolvable Problem

    Directory of Open Access Journals (Sweden)

    Jürgen eSchmidhuber

    2013-06-01

    Full Text Available Most of computer science focuses on automatically solving given computational problems. I focus on automatically inventing or discovering problems in a way inspired by the playful behavior of animals and humans, to train a more and more general problem solver from scratch in an unsupervised fashion. Consider the infinite set of all computable descriptions of tasks with possibly computable solutions. The novel algorithmic framework POWERPLAY (2011 continually searches the space of possible pairs of new tasks and modifications of the current problem solver, until it finds a more powerful problem solver that provably solves all previously learned tasks plus the new one, while the unmodified predecessor does not. Wow-effects are achieved by continually making previously learned skills more efficient such that they require less time and space. New skills may (partially re-use previously learned skills. POWERPLAY's search orders candidate pairs of tasks and solver modifications by their conditional computational (time & space complexity, given the stored experience so far. The new task and its corresponding task-solving skill are those first found and validated. The computational costs of validating new tasks need not grow with task repertoire size. POWERPLAY's ongoing search for novelty keeps breaking the generalization abilities of its present solver. This is related to Goedel's sequence of increasingly powerful formal theories based on adding formerly unprovable statements to the axioms without affecting previously provable theorems. The continually increasing repertoire of problem solving procedures can be exploited by a parallel search for solutions to additional externally posed tasks. POWERPLAY may be viewed as a greedy but practical implementation of basic principles of creativity. A first experimental analysis can be found in separate papers [58, 56, 57].

    Given the increased prevalence of cancer, respiratory diseases, and reproductive disorders, for which multifactorial origins are strongly suspected, the impact of the environment on the population represents a substantial public health challenge. Surveillance systems have become an essential public health decision-making tool. Networks have been constructed to facilitate the development of analyses of the multifactorial aspects of the relationships between occupational contexts and health. The aim of this study is to develop and present an approach for the optimal exploitation of observational databases to describe and improve the understanding of the (occupational) environment–health relationships, taking into account key multifactorial aspects. We have developed a spectral analysis (SA) approach that takes into account both the multi-exposure and dynamic natures of occupational health problems (OHPs) and related associations. The main results of this paper are to present the construction method of the “spectrum” and “spectrosome” of OHPs (range and structured list of occupational exposures) and describe the information contained therein with an illustrative example. The approach is illustrated using the case of non-Hodgkin lymphoma (NHL) from the French National Occupational Diseases Surveillance and Prevention Network database as a working example of an occupational disease. We found that the NHL spectrum includes 40 sets of occupational exposures characterized by important multi-exposures, especially solvent combinations or pesticide combinations, but also specific exposures such as polycyclic aromatic hydrocarbons, formaldehyde and ionizing radiation. These findings may be useful for surveillance and the assessment of occupational exposure related to health risks. PMID:29304043

    Chronic wounds represent a significant burden to patients, health care professionals and the entire health care system. Regarding the healing process, wounds can be classified as acute or chronic wounds. A wound is considered chronic if healing does not occur within the expected period according to the wound etiology and localization. Chronic wounds can be classified as typical and atypical. The majority of wounds (95 percent) are typical ones, which include ischemic, neurotrophic and hypostatic ulcers and two separate entities: diabetic foot and decubital ulcers. Eighty percent of chronic wounds localized on lower leg are the result of chronic venous insufficiency, in 5-10 percent the cause is of arterial etiology, whereas the rest are mostly neuropathic ulcers. Chronic wounds significantly decrease the quality of life of patients by requiring continuous topical treatment, causing immobility and pain in a high percentage of patients. Chronic wounds affect elderly population. Chronic leg ulcers affect 0.6-3 percent of those aged over 60, increasing to over 5 percent of those aged over 80. Emergence of chronic wounds is a substantial socioeconomic problem as 1-2 percent of western population will suffer from it. This estimate is expected to rise due to the increasing proportion of elderly population along with the diabetic and obesity epidemic. It has been proved that chronic wounds account for the large proportion of costs in the health care system, even in rich societies. Socioeconomically, the management of chronic wounds reaches a total of 2-4 percent of the health budget in western countries. Treatment costs for some other diseases are not irrelevant, nor are the method and materials used for treating these wounds. Considering etiologic factors, a chronic wound demands a multidisciplinary approach with great efforts of health care professionals to treat it more efficiently, more simply and more painlessly for the patient, as well as more inexpensively for

    Automatic operation is important for the in-service inspection of nuclear power stations of the decommission of retired plants. Master and slave control will be introduced for work-robot control. It is desirable that the slave possess problem-solving capabilities. In this paper we assume that the slave incorporates the general problem solver (GPS) algorithm. In view of having solved the 'monkey and banana' problem, the slave system is regarded as reasonable alternative which incorporates the capability of problem-solving. Basically, the GPS solves a problem by reducing the difference between the initial state and goal state, and hence the performance of GPS depends on selection of the difference to be reduced. The conventional GPS is given the order of importance of the differences in advance. In this study, the GPS was improved by making use of the rules which determine the order. When several choices are available for the given difference, a fuzzified decision to determine the necessary action is made, as demonstrated in this paper. (author)

    This paper presents an efficient iterative scheme for the generalized Stokes problem, which arises frequently in the simulation of time-dependent Navier-Stokes equations for incompressible fluid flow. The general form of the linear system is where A = {alpha}M + vT is an n x n symmetric positive definite matrix, in which M is the mass matrix, T is the discrete Laplace operator, {alpha} and {nu} are positive constants proportional to the inverses of the time-step {Delta}t and the Reynolds number Re respectively, and B is the discrete gradient operator of size n x k (k < n). Even though the matrix A is symmetric and positive definite, the system is indefinite due to the incompressibility constraint (B{sup T}u = 0). This causes difficulties both for iterative methods and commonly used preconditioners. Moreover, depending on the ratio {alpha}/{nu}, A behaves like the mass matrix M at one extreme and the Laplace operator T at the other, thus complicating the issue of preconditioning.

    Full Text Available Hypertension is considered an important public health problem in Brazil,which is aggravated by its high prevalence and late detection. In addition, it is oneof the major risk factor for cardiovascular and cerebrovascular diseases.Hypertension, considered a “silent murder”, is the largest social problem indeveloped countries and in a large number of developing countries. Despite of knownefficacy and affectivity of various preventive and control measures, including thepharmacological ones, hypertension will continue, for decades, representing oneof the largest health challenges and high cost disease for individuals and society. Ifcontrol of existed cases, as well as control and prevention of risks factors for thisdisease are not implemented, this problematic will affect a large proportion of thepopulation in our country, which, in 2020, will have had increase significantly over60 years of age.Hypertension is a multifactor, multisystem syndrome. It can be cause bymultiple causes, being related to inadequate life style, constitutional factors, suchas: sex, age, race/color and family history; as well as environmental issues, suchas: sedentary lifestyle, stress, smoking, alcoholism, inadequate diet and obesity.Due to its silent course, a person can be surprised by its complications, beingnecessary learn to live with its chronic nature on an every day basis. Nevertheless,this type of problem is influenced by a series of determinants, including personalitycharacteristics, forms to face the disease, self-concept, self-image, experience withthe disease and health care professionals attitudes.One of the difficulties found in the treatment of persons with hypertensionis the lack of adhesion to the treatment, as 50% of the known patients withhypertension don’t treat themselves, and among those who do, few have controlledblood pressure. Between 30 and 50% of persons with hypertension stop treatmentwithin the first year of treatment, and 75% after five

    The automatic operation is important for the in-service inspection of the operating nuclear power station or the decommission of retired plants. The master and slave control will be introduced for work-robot control. It is desirable that the slave involves the capability of problem solving. This paper assumed that the slave involved the general problem solver algorithm. In view of having solved the puzzle of the 'monkey and banana', the slave system is regarded as the reasonable alternative which incorporates the capability of problem solving. Basically, the GPS solves a problem by reducing the difference between an initial state and a goal state, and hence the performance of GPS depends on selecting the difference to be reduced. The usual GPS is given in advance the ordering which indicates the importance of the differences. In this paper, the GPS was improved by making use of the rules which decide the order. When several choices are found on the given difference, the fuzzified decision to determine the action is demonstrated in this paper. (author)

    The master-and-slave control system should be extensively implemented for the in-service inspection of operating nuclear power stations or the decommission of retired plants. The performance of this system depends on the intelligent slave. In this paper the degree of intelligence is approximated by the given amount of prior knowledge or suggestions. This paper aims at improving the general problem solver (GPS) by incorporating the learning process in order to solve the puzzle of the 'monkey and banana'. The monkey in this puzzle may be a reasonable alternative to represent the intelligent slave. Also, this paper deals with fuzzified problem solving since the master's command is not always crisp to the slave. (author)

  3. Some problems in generalized electromagnetic thermoelasticity and wave propagation

    2012-01-01

    The first chapter contains a review of the classical theory of elasticity, the theory of thermodynamics, the theory of uncoupled thermoelasticity, the coupled theory of thermoelasticity, the generalized theory of thermoelasticity with one relaxation time, electromagneto thermoelasticity and an introduction to wave propagation in elastic media. Chapter two is devoted to the study of wave propagation for a problem of an infinitely long solid conducting circular cylinder whose lateral surface is traction free and subjected to a known surrounding temperatures in the presence of a uniform magnetic field in the direction of the axis of the cylinder. Laplace transform techniques are used to derive the solution in the Laplace transform domain. The inversion process is carried out using asymptotic expansions valid for short tines. Numerical results are computed for the temperature, displacement, stress,induced magnetic field and induced electric field distributions. The chapter contains also a study of the wave propagation in the elastic medium. In chapter three, we consider the two-dimensional problem of an infinitely long conducting solid cylinder. The lateral surface of the cylinder is taken to be traction free and is subjected to a known temperature distribution independent of z in the presence of a uniform magnetic field in the direction of the axis of the cylinder. Laplace transform techniques are used. The inversion process is carried out using a numerical method based on Fourier series expansions. Numerical results are computed and represented graphically. The chapter contains also a study of the wave propagation in the elastic medium. In chapter four, we consider a two-dimensional problem for an infinity long cylinder. The lateral surface of the cylinder is taken to be traction free and is subjected to a known temperature distribution independent of φ in the presence of a uniform electric field in the direction of the binomial of the cylinder axis.

    The magnitude which sleep has on personal well-being is similar to the effects of diet and exercise. Sleep deprivation has severe negative effects on an individual's overall health, and this is usually overseen. From 30 to 40 % of the population has presented insomnia at a certain moment of life and from 9 to 15 % have evolved into a chronic and severe insomnia. Recent investigations have related sleep deprivation with obesity, metabolic disorders, heart disease, mental health problems and dementia. Recently, more investigations have focused on the multiple alterations suffered by the immune system in cases of sleep deprivation. In order to make an opportune diagnosis of insomnia, it is vital to obtain a detailed history of the patients' sleep habits. In the physical exam one must search for signs and symptoms which might suggest an organic cause that generates the patient's insomnia. One of the pillars in treatment of these patients consists in acquiring an adequate sleep hygiene based on the optimization of the environment and the behavior that are associated with sleep.

    Mental health problems are common in the work force and influence work capacity and sickness absence. The aim was to examine self-assessed mental health problems and work capacity as determinants of time until return to work (RTW). Employed women and men (n=6140), aged 19-64 years, registered as sick with all-cause sickness absence between February 18 and April 15, 2008 received a self-administered questionnaire covering health and work situation (response rate 54%). Demographic data was collected from official registers. This follow-up study included 2502 individuals. Of these, 1082 were currently off sick when answering the questionnaire. Register data on total number of benefit compensated sick-leave days in the end of 2008 were used to determine the time until RTW. Self-reported persistent mental illness, the WHO (Ten) Mental Well-Being Index and self-assessed work capacity in relation to knowledge, mental, collaborative and physical demands at work were used as determinants. Multinomial and binary logistic regression analyses were used to estimate odds ratios with 95% confidence intervals (CI) for the likelihood of RTW. The likelihood of RTW (≥ 105 days) was higher among those with persistent mental illness OR= 2.97 (95% CI, 2.10-4.20) and those with low mental well-being OR= 2.89 (95% CI, 2.31-3.62) after adjusting for gender, age, SES, hours worked and sick leave 2007. An analysis of employees who were off sick when they answered the questionnaire, the likelihood of RTW (≥ 105 days) was higher among those who reported low capacity to work in relation to knowledge, mental, collaborative and physical demands at work. In a multivariable analysis, the likelihood of RTW (≥ 105 days) among those with low mental well-being remained significant OR=1.93 (95% CI 1.46-2.55) even after adjustment for all dimensions of capacity to work. Self-assessed persistent mental illness, low mental well-being and low work capacity increased the likelihood of prolonged RTW

    Full Text Available Abstract This paper deals with the abstract generalized vector quasi-equilibrium problem in noncompact Hadamard manifolds. We prove the existence of solutions to the abstract generalized vector quasi-equilibrium problem under suitable conditions and provide applications to an abstract vector quasi-equilibrium problem, a generalized scalar equilibrium problem, a scalar equilibrium problem, and a perturbed saddle point problem. Finally, as an application of the existence of solutions to the generalized scalar equilibrium problem, we obtain a weakly mixed variational inequality and two mixed variational inequalities. The results presented in this paper unify and generalize many known results in the literature.

    Full Text Available Abstract Background There is a need for assistance from primary care mental health workers in general practice in the Netherlands. General practitioners (GPs experience an overload of frequent attenders suffering from psychological problems. Problem Solving Treatment (PST is a brief psychological treatment tailored for use in a primary care setting. PST is provided by nurses, and earlier research has shown that it is a treatment at least as effective as usual care. However, research outcomes are not totally satisfying. This protocol describes a randomized clinical trial on the effectiveness of PST provided by nurses for patients in general practice. The results of this study, which currently being carried out, will be presented as soon as they are available. Methods/design This study protocol describes the design of a randomized controlled trial to investigate the effectiveness and cost-effectiveness of PST and usual care compared to usual care only. Patients, 18 years and older, who present psychological problems and are frequent attenders in general practice are recruited by the research assistant. The participants receive questionnaires at baseline, after the intervention, and again after 3 months and 9 months. Primary outcome is the reduction of symptoms, and other outcomes measured are improvement in problem solving skills, psychological and physical well being, daily functioning, social support, coping styles, problem evaluation and health care utilization. Discussion Our results may either confirm that PST in primary care is an effective way of dealing with emotional disorders and a promising addition to the primary care in the UK and USA, or may question this assumption. This trial will allow an evaluation of the effects of PST in practical circumstances and in a rather heterogeneous group of primary care patients. This study delivers scientific support for this use and therefore indications for optimal treatment and referral.

    Berlinguer, G; Falzi, G; Figa-Talamanca, I

    1996-01-01

    Throughout history, the relationship between employers and workers has been subject to the equilibrium of power, to legislative norms, to ethical considerations, and more recently to scientific knowledge. The authors examine the ethical conflicts that arise from the application of scientific knowledge to preventive health policies in the workplace. In particular, they discuss the ethical conflicts in the application of screening practices, in the setting of "allowable limits" of harmful work exposures, and in the right of workers to be informed about work hazards. Ethical problems are also created by conflicting interests in the protection of the environment, the health of the general public, and the health of the working population, and by conflicting interests among workers, and even within the individual worker, as in the case of "fetal protection" policies. The authors emphasize the positive use of scientific information and respect for human dignity in resolving these conflicts.

  11. Synthetic cathinones: a new public health problem.

    New psychoactive substances (NPS) have completely modified the drug scene and the current landscape of addiction. Synthetic substances, such as substituted or synthetic cathinones, also known as « legal highs », are often produced and used to mimic the effects of controlled drugs such as cocaine, methylenedioxymethamphetamine (MDMA, ecstasy), and methamphetamine. The overwhelming majority of synthetic cathinones are produced in China and South East Asian countries. The Internet has emerged as the new marketplace for NPS, playing a major role in providing information on acquisition, synthesis, extraction, identification, and substance use. All these compounds are intentionally mislabeled and sold on-line under slang terms such as bath salts, plant food, plant feeders and research chemicals. They are sometimes labeled « not for human use » or « not tested for hazards or toxicity ». The rapid spread of NPS forces member countries of the European Union to adapt their response to the potential new dangers that may cause. To date, not only health actors but also the general public need to be clearly informed and aware of dangers resulting from NPS spread and use. Here, we review the major clinical effects of synthetic cathinones to highlight their impact on public health. A literature search was conducted from 2009 to 2014 based on PubMed, Google Scholar, Erowid, and governmental websites, using the following keywords alone or in combination: "new psychoactive substances", "synthetic cathinones", "substituted cathinones", "mephedrone", "methylone", "MDPV", "4-MEC", "addiction", and "substance use disorder".

  12. A General Theory of Markovian Time Inconsistent Stochastic Control Problems

    DEFF Research Database (Denmark)

    Björk, Tomas; Murgochi, Agatha

    We develop a theory for stochastic control problems which, in various ways, are time inconsistent in the sense that they do not admit a Bellman optimality principle. We attach these problems by viewing them within a game theoretic framework, and we look for Nash subgame perfect equilibrium points...... examples of time inconsistency in the literature are easily seen to be special cases of the present theory. We also prove that for every time inconsistent problem, there exists an associated time consistent problem such that the optimal control and the optimal value function for the consistent problem...

  13. [Adolescent pregnancy, a public health problem].

    Science.gov (United States)

    Viel Vicuna, B

    1986-01-01

    Throughout Western civilization the fundamental unit of society is the family. The union of a couple guarantees their responsibility to future children. Prior to the renaissance, when life expectancy was very low, the preservation of the human species required reproduction at a young age. Since the beginning of the 19th century, life expectancy has increased greatly. The extremes of reproductive age have been noted to be times when pregnancy carries increase risks, and the risks of grand multiparity have been noted. The sexual revolution has resulted in the loss of previous principles of conduct. Youth are incited by pornography in the media, and without the controlling influence of the traditional family, become sexually active at a younger age. In Chile, as elsewhere, there have always been out of wedlock births, but in 1970 these reached 18.5% of all births. By 1980, it had reached 27.6% of all births and 45.7% of births to mothers under age 20. Since the family is the basic unit of society, this number of illegitimate births indicates a grave social problem. This also represents a public health risk due to the increased risks of young mothers. Illegitimate children of adolescent mothers have the added problem that the fathers are usually also young, so both parents are still in school and cannot assume full responsibility for the child. These babies have a much higher infant mortality than those of older mothers. The only solution is education, and legislation requiring paternal responsibility. School teachers often have an inadequate knowledge of reproduction and sexuality, and can not serve as sources of information to the students. Without supportive education and legislation requiring both parents to be responsible for their children, we will not be able to solve this situation.

  14. SOCIAL NETWORK OPTIMIZATION A NEW METHAHEURISTIC FOR GENERAL OPTIMIZATION PROBLEMS

    2017-12-01

    Full Text Available In the recent years metaheuristics were studied and developed as powerful technics for hard optimization problems. Some of well-known technics in this field are: Genetic Algorithms, Tabu Search, Simulated Annealing, Ant Colony Optimization, and Swarm Intelligence, which are applied successfully to many complex optimization problems. In this paper, we introduce a new metaheuristic for solving such problems based on social networks concept, named as Social Network Optimization – SNO. We show that a wide range of np-hard optimization problems may be solved by SNO.

    1990-01-01

    In the context of a large scale survey of health problems in women aged 50 to 65 years, a study was undertaken on the effects of incontinence on daily life. For this purpose 1442 women randomly selected from the practice files of 75 general practitioners in the eastern part of the Netherlands were interviewed at home (response rate 60%). In cases of moderate or severe incontinence the general practitioner of the woman concerned was asked whether this problem had been diagnosed in general practice. Incontinence was reported in 22.5% of the women. Overall, 77.8% of the women did not feel worried about it and 75.4% did not feel restricted in their activities; even for women with severe incontinence (daily frequency and needing protective pads) only 15.6% experienced much worry and 15.7% much restriction. About a third of the women with incontinence (32.0%) had been identified by their general practitioner. The greater the worries and restrictions owing to incontinence, the greater the chance that the incontinence was known to the general practitioner concerned. Only a small minority of the women who felt severely restricted were not identified by their general practitioner. There was a positive relation between recognized incontinence and a history of hysterectomy. This study contradicts the image of the incontinent woman as isolated and helpless; most women in this study seemed able to cope. PMID:2121179

    To identify the frequency of consumption of alcohol in pregnant women who went to a module of prenatal control; to describe the consumption habits and to identify the number of cases in those that the physician of first level identified the addiction, using the institutional instruments. A descriptive and prospective study was carried out, the study population was selected by means of non randomized sampling of the total of pregnant women who went to receive services of prenatal control, in two units of family medicine of the Mexican Institute of Social Security, of Tapachula, Chiapas, Mexico. The instrument AUDIT (Alcoholism Disorders Identification Test) was used, to identify use-frequency, abuse, dependence and physical/mental damage conditioned by the alcohol. In 132 studied women, it found a frequency of 45.5% of pregnant women with positive consumption and a case of dependence, none of which was identified by the family doctor. The consumption of alcohol in the studied population is high, even bigger than the frequency detected in populations of non pregnant women. The use of detection tests such as the AUDIT and the implementation of measures guided to the training and the personnel's of health sensitization about the magnitude and impact of this problem are recommended.

  18. Is periodontal disease a public health problem?

    Science.gov (United States)

    Batchelor, P

    2014-10-01

    Clinically defined periodontal disease is highly prevalent, has considerable impacts on individuals and society and is costly to treat; the cost of dental care is the fourth highest costs of all diseases and consuming between 5 and 10% of all healthcare resources. Changes in the epidemiology of clinically defined periodontal diseases suggest that the prevalence of severe periodontal disease is low and rates of progression of periodontal destruction tend to be relatively slow. Current periodontal care modalities have a remarkably weak evidence base, with considerable resources allocated to fund interventions that include oral hygiene instruction, scale and polishes through to surgical interventions. The public health problem lies more in the failure in design of a contract between dental professionals and the state. Such a contract needs to recognise both the wider determinants of disease and the role that dental professionals could play: a contract that concentrated on rewarding outcomes, namely a diminution in treatment need, as opposed to one based simply on the number of interventions would be a major step forward.

  19. Spatial Transformation of Equality – Generalized Travelling Salesman Problem to Travelling Salesman Problem

    2018-03-01

    Full Text Available The Equality-Generalized Travelling Salesman Problem (E-GTSP, which is an extension of the Travelling Salesman Problem (TSP, is stated as follows: given groups of points within a city, like banks, supermarkets, etc., find a minimum cost Hamiltonian cycle that visits each group exactly once. It can model many real-life combinatorial optimization scenarios more efficiently than TSP. This study presents five spatially driven search-algorithms for possible transformation of E-GTSP to TSP by considering the spatial spread of points in a given urban city. Presented algorithms are tested over 15 different cities, classified by their street-network’s fractal-dimension. Obtained results denote that the R-Search algorithm, which selects the points from each group based on their radial separation with respect to the start–end point, is the best search criterion for any E-GTSP to TSP conversion modelled for a city street network. An 8.8% length error has been reported for this algorithm.

    Few studies have compared the risks of mental health problems among the adolescents with different levels and different types of bullying involvement experiences. Bullying involvement in 6,406 adolescents was determined through use of the Chinese version of the School Bullying Experience Questionnaire. Data were collected regarding the mental health problems, including depression, suicidality, insomnia, general anxiety, social phobia, alcohol abuse, inattention, and hyperactivity/impulsivity. The association between experiences of bullying involvement and mental health problems was examined. The risk of mental health problems was compared among those with different levels/types of bullying involvement. The results found that being a victim of any type of bullying and being a perpetrator of passive bullying were significantly associated with all kinds of mental health problems, and being a perpetrator of active bullying was significantly associated with all kinds of mental health problems except for general anxiety. Victims or perpetrators of both passive and active bullying had a greater risk of some dimensions of mental health problems than those involved in only passive or active bullying. Differences in the risk of mental health problems were also found among adolescents involved in different types of bullying. This difference in comorbid mental health problems should be taken into consideration when assessing adolescents involved in different levels/types of bullying. © 2014.

    The satisfaction of customer is the main measure and the most important, generally recognized criterion for evaluating the quality of products and services. In the case of education and training, the quality is frequently understood as effectiveness, i.e., the degree to what educational objectives of a training institution are met; the objectives previously formulated on the basis of analyzed and defined demands and expectations of customers (clients). In the first part of the paper: (1) the problems related to the question who in fact is the customer in the context of an institution providing education in public health are discussed; (2) a proposal for resolving these problems is presented; and (3) the main directions of evaluation activities, which should be undertaken under monitoring and effectiveness assessment of postgraduate training in public health are pointed out. In the years 1998-2002, the students' assessment data on educational programs, curriculum contents and subject teachers in the field of postgraduate studies in the School of Public Health, Nofer Institute of Occupational Medicine, Łódź, were collected with the help of specially-designed evaluation questionnaires. The data on the students' self-assessment of gained professional competencies were also collected. All students who completed the School of Public Health in these years were subjected to the evaluation inquiries. The data collected were analyzed. Due to the analysis it was possible to define: the quality of the curriculum contents, as well as the professional and didactic skills of the teaching staff as perceived by the students; the degree to what particular curriculum in public health contributed to the increase in professional competence as perceived by the students; the degree to what particular teaching subjects influenced the students' knowledge of and skills in Public Health. The results obtained provided information very useful in the teaching process, designing of

    Leider, Jonathon P

    2016-01-01

    Accurate information on how much the United States spends on public health is critical. These estimates affect planning efforts; reflect the value society places on the public health enterprise; and allows for the demonstration of cost-effectiveness of programs, policies, and services aimed at increasing population health. Yet, at present, there are a limited number of sources of systematic public health finance data. Each of these sources is collected in different ways, for different reasons, and so yields strikingly different results. This article aims to compare and contrast all 4 current national public health finance data sets, including data compiled by Trust for America's Health, the Association of State and Territorial Health Officials (ASTHO), the National Association of County and City Health Officials (NACCHO), and the Census, which underlie the oft-cited National Health Expenditure Account estimates of public health activity. In FY2008, ASTHO estimates that state health agencies spent $24 billion ($94 per capita on average, median $79), while the Census estimated all state governmental agencies including state health agencies spent $60 billion on public health ($200 per capita on average, median $166). Census public health data suggest that local governments spent an average of $87 per capita (median $57), whereas NACCHO estimates that reporting LHDs spent $64 per capita on average (median $36) in FY2008. We conclude that these estimates differ because the various organizations collect data using different means, data definitions, and inclusion/exclusion criteria--most notably around whether to include spending by all agencies versus a state/local health department, and whether behavioral health, disability, and some clinical care spending are included in estimates. Alongside deeper analysis of presently underutilized Census administrative data, we see harmonization efforts and the creation of a standardized expenditure reporting system as a way to

    Full Text Available Abstract Background In Germany, clinical trials and comparative effectiveness studies in primary care are still very rare, while their usefulness has been recognised in many other countries. A network of researchers from German academic general practice has explored the reasons for this discrepancy. Methods Based on a comprehensive literature review and expert group discussions, problem analyses as well as structural and procedural prerequisites for a better implementation of clinical trials in German primary care are presented. Results In Germany, basic biomedical science and technology is more reputed than clinical or health services research. Clinical trials are funded by industry or a single national programme, which is highly competitive, specialist-dominated, exclusive of pilot studies, and usually favours innovation rather than comparative effectiveness studies. Academic general practice is still not fully implemented, and existing departments are small. Most general practitioners (GPs work in a market-based, competitive setting of small private practices, with a high case load. They have no protected time or funding for research, and mostly no research training or experience. Good Clinical Practice (GCP training is compulsory for participation in clinical trials. The group defined three work packages to be addressed regarding clinical trials in German general practice: (1 problem analysis, and definition of (2 structural prerequisites and (3 procedural prerequisites. Structural prerequisites comprise specific support facilities for general practice-based research networks that could provide practices with a point of contact. Procedural prerequisites consist, for example, of a summary of specific relevant key measures, for example on a web platform. The platform should contain standard operating procedures (SOPs, templates, checklists and other supporting materials for researchers. Conclusion All in all, our problem analyses revealed that

    Full Text Available The paper gives an overview of the problems to be tackled nowadays by occupational health with regards to shift work as well as the main guidelines at organizational and medical levels on how to protect workers’ health and well-being. Working time organization is becoming a key factor on account of new technologies, market globalization, economic competition, and extension of social services to general populations, all of which involve more and more people in continuous assistance and control of work processes over the 24 hours in a day. The large increase of epidemiological and clinical studies on this issue document the severity of this risk factor on human health and well being, at both social and psychophysical levels, starting from a disruption of biological circadian rhythms and sleep/wake cycle and ending in several psychosomatic troubles and disorders, likely also including cancer, and extending to impairment of performance efficiency as well as family and social life. Appropriate interventions on the organization of shift schedules according to ergonomic criteria and careful health surveillance and social support for shift workers are important preventive and corrective measures that allow people to keep working without significant health impairment.

    2016-01-01

    Whereas previous research has indicated that sleep problems tend to co-occur with increased mental health issues in university students, relatively little is known about relations between sleep quality and mental health in university students with generally healthy sleep habits. Understanding relations between sleep and mental health in individuals with generally healthy sleep habits is important because (a) student sleep habits tend to worsen over time and (b) even time-limited experience of sleep problems may have significant implications for the onset of mental health problems. In the present research, 69 university students with generally healthy sleep habits completed questionnaires about sleep quality and mental health. Although participants did not report clinically concerning mental health issues as a group, global sleep quality was associated with mental health. Regression analyses revealed that nighttime sleep duration and the frequency of nighttime sleep disruptions were differentially related to total problems and clinically-relevant symptoms of psychological distress. These results indicate that understanding relations between sleep and mental health in university students with generally healthy sleep habits is important not only due to the large number of undergraduates who experience sleep problems and mental health issues over time but also due to the potential to intervene and improve mental health outcomes before they become clinically concerning.

    International Nuclear Information System (INIS)

    Vacha, J.

    1976-01-01

    On the basis of the present scarce literary data it can be taken as proved that between the numerous properties of the organism usually considered as biologically valuable (high fertility, longevity, higher body weight, resistance to fasting, radiation, and infection agents, certain favorable parameters of CNS) there exist many single and multiple positive correlations. The existence of these correlations allows for the introduction of the working concept of general fitness, stimulating further interdisciplinary research in this field important both in practice and theory. Most correlated manifestations of fitness demonstrated a masked influence of the organism's genotype even though the manner of this manifestation on the phenotype level remains considerably obscure. The efficiency of the haematopoietic system is doubtless one of the mechanisms of general fitness; it is determined by the very complex coordination of several cytokinetic parameters. Important factors are the efficiency of regulation mechanisms at CNS level, the endocrine system, and the regulators of cell populations. Generally highest fitness is connected with a ''balanced'' regulation type, which is characterized by optimal activation of the homeostatic regulation mechanism. In studying the causes of general fitness a systems approach is inevitable which evaluates the levels of individual factors not ''mechanically'' or linearly but from the point of view of the needs of the whole organism and with the application of concepts established by the systems theory (e.g. by the theory of automatic regulation). The sensitivity of an organism to irradiation with ionizing radiation turns out to be a suitable criterion of its general fitness. (author)

    Literature suggests that overweight and obese young people use healthcare services more often, but this awaits confirmation in primary care. To identify health profiles of underweight, overweight and obese young people attending general practice and compare them to normal-weight youth and also to explore the weight-related health risks of eating and exercise behaviour in the four different weight categories. This study used a cross-sectional design with baseline data from a trial including 683 young people (14-24 years of age) presenting to general practice. Through computer-assisted telephone interviews data were obtained on number and type of health complaints and consultations, emotional distress, health-related quality of life (HRQoL) and eating and exercise behaviour. General practitioners (GPs) were consulted more often by overweight (incidence rate ratio (IRR): 1.28, 95% CI (1.04 to 1.57)) and obese youth (IRR: 1.54, 95% CI (1.21 to 1.97), but not for different health problems compared with normal-weight youth. The reason for presentation was seldom a weight issue. Obese youth reported lower physical HRQoL. Obese and underweight youth were less likely to be satisfied with their eating behaviour than their normal-weight peers. Exercise levels were low in the entire cohort. Our study highlights the need for effective weight management given that overweight and obese youth consult their GP more often. Since young people do not present with weight issues, it becomes important for GPs to find ways to initiate the discussion about weight, healthy eating and exercise with youth. ISRCTN16059206.

    We study the correlations of the energy-momentum tensor for classically conformally invariant generalized σ-models in the Wilson operator-product-expansion approach. We find that these correlations are, in general, infrared divergent. The absence of infrared divergences is obtained, as one can expect, for σ-models on a group manifold or for σ-models with a string-like interpretation. Moreover, the infrared divergences spoil the naive scaling arguments used by Zamolodchikov in the demonstration of the C-theorem. (orig.)

    Two global existence conjectures for the Einstein equations are formulated and their relevance to the cosmic censorship conjecture discussed. It is argued that the reformulation of the cosmic censorship conjecture as a global existence problem renders it more amenable to direct analytical attack. To demonstrate the facility of this approach the cosmological version of the global existence conjecture is proved for the Gowdy spacetimes on T 3 X R. (author)

    1992-08-01

    The aim was to examine the scale, source, and relevance of variation between general practices in respect of the rates with which patients consulted with illnesses falling in each of several diagnostic groups. This study involved a general practice morbidity survey conducted over two years, 1970-72. All patients who consulted their general practitioners were identified and the number of these who consulted with diagnoses attributable to each of the 18 main chapters of the International classification of diseases were counted. Patients who consulted for more than one diagnosis within a chapter were counted once only; those who consulted for one or more diagnoses in each of several chapters were counted once for each chapter. This was a national survey involving general practitioners in England and Wales. The study involved 214,524 patients from 53 selected general practices (115 doctors) who were registered with their general practitioners for the whole of the year 1970-71 and for whom their morbidity data had been linked with their social data from the 1971 census. Using the numbers of patients on the practice lists as denominators, practice patient consulting rates (PPCR) were calculated for each practice and for each ICD chapter. Variability in chapter PPCR was examined by calculating coefficients of variation and, after allowance for random variation, coefficients of residual variation. There were large interpractice (doctor) variations in all chapter rates. These variations were only marginally attributable to: chance; different age, sex and social class mixes of practice populations; geographical locations; and practice organisation. The rates were, however, consistent from one year to the next for any one practice. Approximately half of the interpractice (doctor) diagnostic variability was associated with overall patient consulting behaviour. When the effects of this behaviour were discounted, any major residual diagnostic variability was confined largely to

    Full Text Available INTRODUCTION: Literature suggests that good quality health care access can have a positive impact on the health of people with serious mental illness (SMI, but literature relating to patterns of access by this group is equivocal. AIM: This study was designed to explore health care access patterns in a group of people with SMI and to compare them with a general New Zealand population group, in order for health providers to understand how they might contribute to positive health outcomes for this group. METHODS: The study surveyed 404 mental health consumers aged 18-65 years receiving care from one district health board in Auckland about their patterns of health care access. Results were compared with those from the New Zealand Health Survey of the general population. RESULTS: Findings suggest that the SMI consumer respondents had poorer physical health than the general population respondents, accessed health care services in more complex ways and were more particular about who they accessed for their care than the general population respondents. There was some concern from SMI consumers around discrimination from health care providers. The study also suggested that some proactive management with SMI consumers for conditions such as metabolic syndrome was occurring within the health care community. DISCUSSION: The first point of access for SMI consumers with general health problems is not always the family general practitioner and so other health professionals may sometimes need to consider the mental and physical health of such consumers in a wider context than their own specialism.

    Full Text Available All general anesthetics routinely used in clinical practice are noted to have a neurotoxic effect on the brain in different animal species including primates. The negative effects observed both in young and sexually mature animals include apoptotic neuronal cell death, suppression of neurogenesis and gliogenesis, neuroinflammation, as well as learning and memory impairments. A number of epidemiologic surveys have established an association between anesthesia in patients younger than 3 to 4 years and subsequent learning disabilities and language disorders whereas others have not found this link. In middle-aged and elderly patients, anesthesia is frequently associated with the development of postoperative cognitive dysfunction. The key component of its pathogenesis (general anesthesia itself or other factors, such as operative injury, an inflammatory response, pain syndrome, intraoperative complications, underlying disease in a patient remains unelucidated. It is concluded that there is a need for additional experimental and clinical studies of the pathogenesis of these undesirable phenomena to be prevented and corrected.

The Hamilton-Jacobi equation for a test charged particle in GRT is used. The general form of the generalized momentum dependence on the initial values is determined. It is noted that the inverse problem solution of dynamics in GRT contains arbitrariness which depends on the choice of the metric and potential values of the electromagnetic field in the nonsingular point [ru

    Problem gambling attracts considerable public stigma, with deleterious effects on mental health and use of healthcare services amongst those affected. However, no research has examined the extent of stigma towards problem gambling within the general population. This study aimed to examine the stigma-related dimensions of problem gambling as perceived by the general public compared to other health conditions, and determine whether the publicly perceived dimensions of problem gambling predict its stigmatisation. A sample of 2000 Australian adults was surveyed, weighted to be representative of the state population by gender, age and location. Based on vignettes, the online survey measured perceived origin, peril, concealability, course and disruptiveness of problem gambling and four other health conditions, and desired social distance from each. Problem gambling was perceived as caused mainly by stressful life circumstances, and highly disruptive, recoverable and noticeable, but not particularly perilous. Respondents stigmatised problem gambling more than sub-clinical distress and recreational gambling, but less than alcohol use disorder and schizophrenia. Predictors of stronger stigma towards problem gambling were perceptions it is caused by bad character, is perilous, non-recoverable, disruptive and noticeable, but not due to stressful life circumstances, genetic/inherited problem, or chemical imbalance in the brain. This new foundational knowledge can advance understanding and reduction of problem gambling stigma through countering inaccurate perceptions that problem gambling is caused by bad character, that people with gambling problems are likely to be violent to other people, and that people cannot recover from problem gambling.

    1976-01-01

    The use of radioautography for neurotransmitter studies requires two preliminary conditions (in addition to the availability of tritiated molecules): there must be a selective uptake of the neurotransmitter itself, or of a related substance (precursor or false transmitter); the labelled substance must be preserved in situ by fixation and must not be removed by further treatments. Since the putative neurotransmitters are generally small, hydrosoluble molecules, they can be maintained in situ only if they are bound to structure made insoluble by the fixative. The technical indications are summarized so that the successive stages of experimentation can be considered in an attempt to answer the major questions posed by the experimenter

    Watson, Michael

    2008-01-01

    The World Health Organization's Ottawa Charter for Health Promotion has been influential in guiding the development of 'settings' based health promotion. Over the past decade, settings such as schools have flourished and there has been a considerable amount of academic literature produced, including theoretical papers, descriptive studies and evaluations. However, despite its central importance, the health-promoting general practice has received little attention. This paper discusses: the significance of this setting for health promotion; how a health promoting general practice can be created; effective health promotion approaches; the nursing contribution; and some challenges that need to be resolved. In order to become a health promoting general practice, the staff must undertake a commitment to fulfil the following conditions: create a healthy working environment; integrate health promotion into practice activities; and establish alliances with other relevant institutions and groups within the community. The health promoting general practice is the gold standard for health promotion. Settings that have developed have had the support of local, national and European networks. Similar assistance and advocacy will be needed in general practice. This paper recommends that a series of rigorously evaluated, high-quality pilot sites need to be established to identify and address potential difficulties, and to ensure that this innovative approach yields tangible health benefits for local communities. It also suggests that government support is critical to the future development of health promoting general practices. This will be needed both directly and in relation to the capacity and resourcing of public health in general.

    1996-01-01

    During the sixties, governments have installed hot nuclear materials research facilities to characterize highly radioactive materials, to describe their in-pile behaviour, to develop and test new reactor core components, and to provide the industry with radioisotopes. Since then, the attitude towards the nuclear option has drastically changed and resources have become very tight. Within the changed political environment, the national research centres have defined new objectives. Given budgetary constraints, nuclear facilities have to co-operate internationally and to look for third party research assignments. The paper discusses the problems and needs within experimental nuclear research facilities as well as industrial requirements. Special emphasis is on cultural topics (definition of the scope of nuclear research facilities, the search for competitive advantages, and operational requirements), social aspects (overageing of personnel, recruitment, and training of new staff), safety related administrative and technical issues, and research needs for expertise and state of the art analytical infrastructure

    Greenhouse gases and greenhouse effect principles are reviewed and climate changes due to the human activities are discussed: identification of gases, human or natural causes, composition evolution in the atmosphere and relative roles of greenhouse gases. The various tools and calculations methods for evaluating the climate change due to greenhouse effect are presented. Several problems are stated: evolution of the climate structure in 2030, variations of the climatic extremes and the extreme phenomena, augmentation or diminution of the storms on a warmed planet, long term evolution of the climate. Some consequences of a climate change are reviewed: sea level raising, climate change effects on ecosystems. Precision and validity of these predictions are discussed; recommendations for diminishing the uncertainties are proposed

    In the face of limited resources and an aging population with increasingly care needs, healthcare systems must identify community-dwelling older adults with mental health problems at higher risk of adverse outcomes such as institutionalization, hospitalization and death, in order to deliver timely and efficient care. The objectives of this study were to assess the prevalence of mental health concerns and the associated perceived risk of adverse outcomes in a large sample of older patients in primary care (PC). We trained general practitioners and nurses to use the Risk Instrument for Screening in the Community to rank perceived risk of mental health concerns (including neurocognitive and mood disorders) from 1 (mild) to 3 (severe). The mean age of the 4499 people assessed was 76.3 years (SD = 7.3) and 2645 (58.8%) were female. According to the PC team 1616 (35.9%) were perceived to have mental health concerns of whom 847 (52.4%) were mild, 559 (34.6%) were moderate and 210 (13%) were severe. Patients with mental health concerns had higher odds of perceived risk of adverse outcomes (OR = 2.22, 95% CI 1.83-2.69 for institutionalization; OR = 1.66, 95% CI 1.41-1.94 for hospitalization; OR = 1.69, 95% CI 1.42-2.01 for death). These results suggest a high prevalence of mental health concerns among older adults and supports the need for early identification of patients at high-risk of adverse healthcare outcomes.

Aim of this review has been to present the current state of knowledge about the impact of e-cigarette use on health, with an emphasis on Central and Eastern Europe. During the preparation of this narrative review, the literature on e-cigarettes available within the network PubMed was retrieved and examined. In the final review, 64 research papers were included. We specifically assessed the construction and operation of the e-cigarette as well as the chemical composition of the e-liquid; the impact that vapor arising from the use of e-cigarette explored in experimental models in vitro; and short-term effects of use of e-cigarettes on users’ health. Among the substances inhaled by the e-smoker, there are several harmful products, such as: formaldehyde, acetaldehyde, acroleine, propanal, nicotine, acetone, o-methyl-benzaldehyde, carcinogenic nitrosamines. Results from experimental animal studies indicate the negative impact of e-cigarette exposure on test models, such as ascytotoxicity, oxidative stress, inflammation, airway hyper reactivity, airway remodeling, mucin production, apoptosis, and emphysematous changes. The short-term impact of e-cigarettes on human health has been studied mostly in experimental setting. Available evidence shows that the use of e-cigarettes may result in acute lung function responses (e.g., increase in impedance, peripheral airway flow resistance and induce oxidative stress.

    Full Text Available Abstract This paper is dedicated to the introduction a new class of equilibrium problems named generalized multivalued equilibrium-like problems which includes the classes of hemiequilibrium problems, equilibrium-like problems, equilibrium problems, hemivariational inequalities, and variational inequalities as special cases. By utilizing the auxiliary principle technique, some new predictor-corrector iterative algorithms for solving them are suggested and analyzed. The convergence analysis of the proposed iterative methods requires either partially relaxed monotonicity or jointly pseudomonotonicity of the bifunctions involved in generalized multivalued equilibrium-like problem. Results obtained in this paper include several new and known results as special cases.

  19. Is vitamin D deficiency a major global public health problem?

    Palacios, Cristina; Gonzalez, Lilliana

    2014-10-01

    Vitamin D deficiency is a major public health problem worldwide in all age groups, even in those residing in countries with low latitude, where it was generally assumed that UV radiation was adequate enough to prevent this deficiency, and in industrialized countries, where vitamin D fortification has been implemented now for years. However, most countries are still lacking data, particularly population representative data, with very limited information in infants, children, adolescents and pregnant women. Since the number of recent publications is escalating, with a broadening of the geographic diversity, the objective of the present report was to conduct a more recent systematic review of global vitamin D status, with particular emphasis in at risk groups. A systematic review was conducted in PubMed/Medline in April-June 2013 to identify articles on vitamin D status worldwide published in the last 10 years in apparently healthy individuals. Only studies with vitamin D status prevalence were included. If available, the first source selected was population-based or representative samples studies. Clinical trials, case-control studies, case reports or series, reviews, validation studies, letters, editorials, or qualitative studies were excluded. A total of 103 articles were eligible and included in the present report. Maps were created for each age group, providing an updated overview of global vitamin D status. In areas with available data, the prevalence of low vitamin D status is a global problem in all age groups, in particular in girls and women from the Middle East. These maps also evidenced the regions with missing data for each specific population groups. There is striking lack of data in infants, children and adolescents worldwide, and in most countries of South America and Africa. In conclusion, vitamin D deficiency is a global public health problem in all age groups, particularly in those from the Middle East. This article is part of a Special Issue

    We derive a general ansatz for optimizing pseudo-C l estimators used to measure cosmic microwave background anisotropy power spectra, and apply it to the recently proposed pure pseudo-C l formalism, to obtain an estimator which achieves near-optimal B-mode power spectrum errors for any specified noise distribution while minimizing leakage from ambiguous modes. Our technique should be relevant for upcoming cosmic microwave background polarization experiments searching for B-mode polarization. We compare our technique both to the theoretical limits based on a full Fisher matrix calculation and to the standard pseudo-C l technique. We demonstrate it by applying it to a fiducial survey with realistic inhomogeneous noise, complex boundaries, point source masking, and a noise level comparable to what is expected for next-generation experiments (∼5.75 μK-arcmin). For such an experiment our technique could improve the constraints on the amplitude of a gravity wave background by over a factor of 10 compared to what could be obtained using ordinary pseudo-C l , coming quite close to saturating the theoretical limit. Constraints on the amplitude of the lensing B-modes are improved by about a factor of 3

    The principal purpose of this paper is to present a comprehensive overview of generalized information theory (GIT): a research program whose objective is to develop a broad treatment of uncertainty-based information, not restricted to classical notions of uncertainty. After a brief overview of classical information theories, a broad framework for formalizing uncertainty and the associated uncertainty-based information of a great spectrum of conceivable types is sketched. The various theories of imprecise probabilities that have already been developed within this framework are then surveyed, focusing primarily on some important unifying principles applying to all these theories. This is followed by introducing two higher levels of the theories of imprecise probabilities: (i) the level of measuring the amount of relevant uncertainty (predictive, retrodictive, prescriptive, diagnostic, etc.) in any situation formalizable in each given theory, and (ii) the level of some methodological principles of uncertainty, which are contingent upon the capability to measure uncertainty and the associated uncertainty-based information. Various issues regarding both the measurement of uncertainty and the uncertainty principles are discussed. Again, the focus is on unifying principles applicable to all the theories. Finally, the current status of GIT is assessed and future research in the area is discussed

    The aim of this study was to explore people's experiences, concerns and beliefs about disclosing minor mental health problems by focusing on the ways in which such disclosures are interpreted. Approximately half of people with mental health problems do not seek help. The decision to consult represents just one aspect of the process of revealing one's illness to others. People with mental health problems are known to be reluctant to reveal the existence of those problems through fear of how others might then view them. A qualitative approach was employed. In-depth interviews were carried out with 47 users and nonusers of community mental health services. Interviews were tape-recorded, transcribed and analysed. The data suggest that when people reveal minor mental health problems others interpret these in relation to a number of perceived contextual factors. These include perceptions of the severity and duration of any possible causes, the inner 'strength' of the person, the expected ability of the person to either solve or suppress the experience, and the form and context of the expression itself. The data presented included individuals who were seeking help for relatively 'minor' mental health problems (primarily depression and anxiety) and individuals who had no current mental health problems but routinely managed expressions of their own emotions. Throughout the data there appeared to be no distinct difference between these two groups other than one of the severity of psychological experience. The key elements involved in the interpretation of people's expressions of sadness were essentially the same as those involved in the interpretation of expressions of depression. An appreciation of these contextual factors influencing the interpretation and disclosure of minor mental health problems may aid the development of more person-centred mental health services and inform the content of health education in the mental health field.

    The aim of this study was to explore Palestinian mothers' perceptions of child mental health problems and their understanding of their causes; to determine Palestinian mothers' awareness of existing services and sources of help and support; to identify professionals in the community whom Palestinian mothers would consult if their child had mental health problems; and to establish their views on ways of increasing awareness of child mental health issues and services. Checklists exploring the above issues were completed by 249 Palestinian mothers living in refugee camps in the Gaza Strip. Palestinian mothers equally perceived emotional, behavioural and psychotic symptoms as suggestive of mental ill health in childhood. Mothers perceived multiple causes of child mental health problems, including family problems, parental psychiatric illness and social adversity. A substantial proportion (42.6%) had knowledge of local child mental health care services. Overall, mothers preferred Western over traditional types of treatment, and were keen to increase mental health awareness within their society. Despite a different cultural tradition, Palestinian mothers appear open to a range of services and interventions for child mental health problems. As in other non-Western societies, child mental health service provision should be integrated with existing primary health care, schools, and community structures. PMID:16946953

    Full Text Available Globally, the number of life expectancy in worldwide population has increased compared with 1990. In 2014, the mean life expectancy have reached 75 years old, and even above 80 years in several developed countries. The interesting point is women have shown higher increase of live expectancy compared with men, Women have increased 6.6 years compared with men, 5.8 years. Better health welfare, economic  growth, and lifestyle modification suspected to be contributing in higher life expectancy worldwide. Despite the encouraging news that the age of population is increasing, the concern will be whether this longer age come with the better health condition, including oral and dental health. The presence of teeth inside the mouth is one of significant points to support one’s quality of life. This research involved 66 subjects, age between 35–60 years old, divided into two groups, menopause and non-menopause women. The research shown that tooth loss occurred more in non-menopause women than menopause woman, which is 37% woman has lost as many as 12 teeth, compared with post menopausal the toothloss only occurred in 19.6%. The treatment need of non-surgery periodontal care in non-menopausal woman higher by 37.9%, and surgery care is 23.2%, meanwhile in the menopause group, non surgery care is 30.3% and surgery care is only 9.1%. The conclusion is the teeth extractions mostly take place in the period before menopause compared post-menopausal. Treatment need is also higher before menopausal than after menopause. In order to that, the menopausal women need to have adequate dental care by the patient and the dentist as well

    Radiation hygiene problems of industrial radioisotope applications are discussed. The observance of regulations is emphasised. Radiation protection is based on the principle of preventing early radiation damage and limiting late radiation damage to an acceptable level. The basic requirement is that the cumulated dose should be as low as possible, i.e., as low as is practically feasible in considering economic and social aspects. Notices 59/72 and 65/72, Collection of Laws, rule that if the limit of 3/10 of the maximum permissible dose is likely to be reached, control zones should be defined and marked at places of work where radioisotopes are handled. The characteristics of such a control zone are listed and the measures to be taken in case of accident are outlined. (B.S.)

    Ionizing radiation, first as x-rays, later in natural form, was discovered in Europe in the late 1890's. Immediate practical uses were found for these discoveries, particularly in medicine. Unfortunately, because of the crude early equipment and ignorance of the harmful effects of radiation, many people were injured, some fatally. Because of these experiences, committees and regulatory bodies were set up to study the problem. These have built up an impressive fund of knowledge useful in radiation protection.With the recent development of the peaceful uses of atomic energy, sources of radioactivity have appeared cheaply and in abundance. A rapidly growing number are finding industrial application. Because of their potential risk to humans, the industrial physician must acquire new knowledge and skills so that he may give proper guidance in this new realm of preventive medicine.The Radiation Protection Program of one such industry, the Hydro-Electric Power Commission of Ontario, is summarized.

    To assess the availability of on-site mental health professionals (MHPs) in primary care; to examine practice/pediatrician characteristics associated with on-site MHPs; and to determine whether the presence of on-site MHPs is related to pediatricians' comanaging or more frequently identifying, treating/managing, or referring mental health (MH) problems. Analyses included American Academy of Pediatrics (AAP) members who participated in an AAP Periodic Survey in 2013 and who practiced general pediatrics (n = 321). Measures included sociodemographics, practice characteristics, questions about on-site MHPs, comanagement of MH problems, and pediatricians' behaviors in response to 5 prevalent MH problems. Weighted univariate, bivariate, and multivariable analyses were performed. Thirty-five percent reported on-site MHPs. Practice characteristics (medical schools, universities, health maintenance organizations, managed, or referred 5 common child MH problems. Among the subset of pediatricians who reported comanaging, there was an association with comanagement when the on-site MHP was a child psychiatrist, substance abuse counselor, or social worker. On-site MHPs are more frequent in settings where low-income children are served and where pediatricians train. Pediatricians who comanage MH problems are more likely to do so when the on-site MHP is a child psychiatrist, substance abuse counselor, or social worker. Overall, on-site MHPs were not associated with comanagement or increased likelihood of pediatricians identifying, treating/managing, or referring children with 5 common child MH problems.

    Prader-Willi syndrome (PWS) is a genetic disorder which is characterized by severe hypotonia and feeding problems in early infancy. In later childhood and adolescence, this is followed by hyperphagia and extreme obesity if the diet is not strictly controlled. Data on physical health problems in adults with PWS are scarce. We report on the prevalence of physical health problems in a Dutch cohort of adults with PWS in relation to age, BMI, and genetic subtype. Participants (n = 102) were retrieved via the Dutch Prader-Willi Parent Association and through physicians specializing in persons with intellectual disabilities (ID). Details regarding physical health problem spanning the participants' lifespan were collected from caretakers through semi-structured interviews. Cardiovascular problems included diabetes mellitus, hypertension, and cerebrovascular accidents. Respiratory infections were frequent in adulthood. In males, cryptorchidism was almost universal, for which 28/48 males had a history of surgery, mostly orchidopexy. None of the women had a regular menstrual cycle. Sixteen individuals had a diagnosis of osteoporosis. Spinal deformation, hip dysplasia, and foot abnormalities were common. Skinpicking, leg edema, and erysipelas were frequent dermatological problems. The findings in our group support the notion that the prevalence of physical health problems is underestimated. This underscores the importance of developing monitoring programs which would help to recognize physical health problems at an early stage. Copyright © 2011 Wiley-Liss, Inc.

  13. Non-ionizing radiation and health protection problems

    Wavelength and frequency are two closely related properties which determine the characteristics of any particular type of electromagnetic radiation and which can be used interchangeably to describe it. For protection purposes the determination of the energy absorbed (absorbed dose) and of its distribution within living systems, whatever the radiation concerned, is still one of the chief problems to be solved. Therefore, although thermal effects are often prevailing, no appropriate dose-effect relationships could be established in most cases and more particularly as far as non-thermal effects are concerned. The problems associated with the different types of NIR are briefly reviewed. An increasing number of countries is promulgating regulatory measures for limiting exposure to NIR of occupationally exposed individuals and of the general population. Harmonization of basic concepts and internationally acceptable protection standards are therefore urgently needed. IRPA is probably the only international, non-governmental scientific organization able to promote wide international and interdisciplinary cooperation in the field of health protection against NIR. Therefore, after having carefully considered the situation, IRPA felt that it was its responsibility to produce guidance on basic protection criteria and standards and created the International NIR-Committee with the objective of developing background documents and internationally accepted recommendations

    Jane Scott and colleagues have recently published a paper in the International Breastfeeding Journal showing that health professionals are still giving harmful advice to women with mastitis. We see the management of mastitis as an illustration of health professionals' management of wider breastfeeding issues. If health professionals don't know how to manage this common problem, how can they be expected to manage less common conditions such as a breast abscess or nipple/breast candidiasis? There is an urgent need for more clinical research into breastfeeding problems and to improve the education of health professionals to enable them to promote breastfeeding and support breastfeeding women.

    Previous research has found that mental health is strongly associated with life satisfaction. In this study we examine associations between mental health problems and life satisfaction in a birth cohort studied from 18 to 35 years. Data were gathered during the Christchurch Health and Development Study, which is a longitudinal study of a birth cohort of 1265 children, born in Christchurch, New Zealand, in 1977. Assessments of psychiatric disorder (major depression, anxiety disorder, suicidality, alcohol dependence and illicit substance dependence) using DSM diagnostic criteria and life satisfaction were obtained at 18, 21, 25, 30 and 35 years. Significant associations (p life satisfaction and the psychiatric disorders major depression, anxiety disorder, suicidality, alcohol dependence and substance dependence. After adjustment for non-observed sources of confounding by fixed effects, statistically significant associations (p life satisfaction and major depression, anxiety disorder, suicidality and substance dependence. Overall, those reporting three or more mental health disorders had mean life satisfaction scores that were nearly 0.60 standard deviations below those without mental health problems. A structural equation model examined the direction of causation between life satisfaction and mental health problems. Statistically significant (p life satisfaction and mental health problems. After adjustment for confounding, robust and reciprocal associations were found between mental health problems and life satisfaction. Overall, this study showed evidence that life satisfaction influences mental disorder, and that mental disorder influences life satisfaction.

  18. Iodine insufficiency: a global health problem?

    As a result of collaborative efforts with international organizations and the salt industry, many developing and developed countries practice universal salt iodization (USI) or have mandatory salt fortification programs. As a consequence, the prevalence of iodine deficiency decreased dramatically. The United States and Canada are among the few developed countries that do not practice USI. Such an undertaking would require evidence of deficiency among vulnerable population groups, including pregnant women, newborns, and developing infants. Government agencies in the United States rely heavily on data from NHANES to assess the iodine status of the general population and pregnant women in particular. NHANES data suggest that pregnant women in the United States remain mildly deficient. This is important, because the developing fetus is dependent on maternal iodine intake for normal brain development throughout pregnancy. Professional societies have recommended that pregnant and lactating women, or those considering pregnancy, consume a supplement providing 150 μg iodine daily. The United States and Canada collaborate on the daily recommended intake and are also confronted with the challenge of identifying the studies needed to determine if USI is likely to be beneficial to vulnerable population groups without exposing them to harm.

  19. Recycling Biowaste – Human and Animal Health Problems

    Full Text Available Biowaste from the food chain is of potential benefit to use in agriculture. Agriculture in general and organic farming in particular needs alternative plant nutrients. However, the quality concerning hygiene and soil contaminants must be assured. This recycling has to be regulated in a way that harmful effects on soil, vegetation, animals and man are prevented. The problems with heavy metals and organic contaminants have been focused on. Still, maximum threshold values are continuously discussed to avoid an increase of soil concentrations. The effect on the ecosystems of residues from use of medicines needs further attention. There is also a risk for a spread of antibiotic resistant micro-organisms in the environment and then to animals and man. Infectious diseases may be spread from biowaste and new routes of disease transmission between animals and humans can be created. Zoonotic diseases in this context play a central role. Pathogens recently introduced to a country may be further spread when biowaste is recycled. The very good health status of domestic animals in the Nordic countries may then quickly change. The quality of biowaste is of enormous importance if biowaste is to gain general acceptance for agricultural use, especially for organic production. A balance needs to be maintained between risk and advantage for its use.

    Agnès Fleury

    Full Text Available BACKGROUND: The ongoing epidemiological transition in Mexico minimizes the relative impact of neurocysticercosis (NC on public health. However, hard data on the disease frequency are not available. METHODOLOGY: All clinical records from patients admitted in the Instituto Nacional de Neurologia y Neurocirugia (INNN at Mexico City in 1994 and 2004 were revised. The frequencies of hospitalized NC patients in neurology, neurosurgery and psychiatry services, as well as NC mortality from 1995 through 2009, were retrieved. Statistical analyses were made to evaluate possible significant differences in frequencies of NC patients' admission between 1994 and 2004, and in yearly frequencies of NC patients' hospitalization and death between 1995 and 2009. PRINCIPAL FINDINGS: NC frequency in INNN is not significantly different in 1994 and 2004. Between these two years, clinical severity of the cases diminished and the proportion of patients living in Mexico City increased. Yearly frequencies of hospitalization in neurology and psychiatry services were stable, while frequencies of hospitalization in neurosurgery service and mortality significantly decreased between 1995 and 2009. CONCLUSIONS: Our findings show a stable tendency of hospital cases during the last decade that should encourage to redouble efforts to control this ancient disease.

    One of the most significant changes in modern healthcare delivery has been the evolution of the paper record to the electronic health record (EHR). In this paper we argue that the primary change has been a shift in the focus of documentation from monitoring individual patient progress to recording data pertinent to Institutional Priorities (IPs). The specific IPs to which we refer include: finance/reimbursement; risk management/legal considerations; quality improvement/safety initiatives; meeting regulatory and accreditation standards; and patient care delivery/evidence based practice. Following a brief history of the transition from the paper record to the EHR, the authors discuss unintended or contested consequences resulting from this change. These changes primarily reflect changes in the organization and amount of clinician work and clinician-patient relationships. The paper is not a research report but was informed by an institutional ethnography the aim of which was to understand how the EHR impacted clinicians and administrators in a large, urban hospital in the United States. The paper was also informed by other sources, including the philosophies of Jacques Ellul, Don Idhe, and Langdon Winner. © 2015 John Wiley & Sons Ltd.

    Children's mental health has significant implications for functioning across home, school, and community settings. The infant to preschool years has been found to be a crucial stage in a child’s development. As such, problems that arise during these years are likely to impact a child’s social and emotional development if no treatment is sought. Childhood mental health problems affect up to almost one quarter of children globally (Belfer, 2008; Canino, Bird, Rubio-Stipec, & Bravo, 1995; Egger ...

    The Journal presents the Column of Case Studies of Mental Health in General Practice;with aca-demic support from Australian eXperts in general practice,psychology and psychiatry from Monash University and the University of Mel-bourne. The Columnˊs purpose is to respond to the increasing need for the development of mental health services in China. Through study and analysis of mental health cases,we hope to improve understanding of mental illnesses in Chinese primary health settings,and to build capaci-ty amongst community health professionals in managing mental illnesses and psychological problems in general practice. A patient - centred whole - person approach in general practice is the best way to maintain and improve the physical and mental health of residents. Our hope is that these case studies will lead the new wave of general practice and mental health service development both in practice and research. A num-ber of Australian eXperts from the disciplines of general practice,mental health and psychiatry will contribute to the Column. Professor Blash-ki,Professor Judd and Professor Piterman are authors of the teXt General Practice Psychiatry;the Chinese version of the book to be published in 2014. The Journal cases are helping to prepare for the translation and publication of a Chinese version of the book in China. We believe Chi-nese mental health in primary health care will reach new heights under this international cooperation.

    This study was conducted to determine the relationship between prayer attendance and general health among adult urban population in Iran. A total of 470 males older than 17 years, chosen by multistage sampling, were investigated. The results showed that people who did not perform prayers compared to those who said prayers on time and performed Nafilahs (supererogatory prayers) were 2.87 (OR 2.87, 95 % CI 1.23-6.70, p = 0.015) times at risk of general health problems. In conclusion, the findings show that increasing the degree of people's belief in prayer can lead to improve general health.

    Women entering the correctional system represent a population at high risk for mental health and the body of research on the mental health needs of women offenders is growing. These mental health problems pose challenges for women at every stage of the criminal justice process, from arrest to incarceration to community reentry and reintegration. In this article, we examined mental health status among a sample of 142 women leaving confinement and the role that mental health problems played in shaping their reentry outcomes using data collected between 2002 and 2005 in Houston, Texas. In the year after leaving prison, women with mental health problems reported poorer health, more hospitalizations, more suicidal thoughts, greater difficulties securing housing and employment, more involvement in criminal behavior, and less financial support from family than women with no indication of mental health problems. However, mental health status did not increase the likelihood of substance use relapse or reincarceration. The article concludes with a discussion of recommendations for improved policy and practice.

    Full Text Available Abstract Background Little is known about the health status of prisoners in Switzerland. The aim of this study was to provide a detailed description of the health problems presented by detainees in Switzerland's largest remand prison. Methods In this retrospective cross-sectional study we reviewed the health records of all detainees leaving Switzerland's largest remand prison in 2007. The health problems were coded using the International Classification for Primary Care (ICPC-2. Analyses were descriptive, stratified by gender. Results A total of 2195 health records were reviewed. Mean age was 29.5 years (SD 9.5; 95% were male; 87.8% were migrants. Mean length of stay was 80 days (SD 160. Illicit drug use (40.2% and mental health problems (32.6% were frequent, but most of these detainees (57.6% had more generic primary care problems, such as skin (27.0%, infectious diseases (23.5%, musculoskeletal (19.2%, injury related (18.3%, digestive (15.0% or respiratory problems (14.0%. Furthermore, 7.9% reported exposure to violence during arrest by the police. Conclusion Morbidity is high in this young, predominantly male population of detainees, in particular in relation to substance abuse. Other health problems more commonly seen in general practice are also frequent. These findings support the further development of coordinated primary care and mental health services within detention centers.

A positive mental health state indicates that the individual enjoys his routine; there are no undue conflicts. Health reiteration become s more imperative than health maintenanc e, where society’s responsibility is paramount. Health economics enables us to examine the burden caused by illness. In India, 620 million people live in rural area; only 9% of every one billion populatio n is covered under health schemes. Only 2% of GDP is spent on health, where the recommended percentage is 5%. In addition to this only 5% of annual family income is spent on curative health care. In the recent past rapid deterioration in the quality of environment has over - burdened the health problem. Occu pational Health is one of the environmental health sciences, concerned broadly with the health effects of work and of working conditions. Occupational illnesses and injuries have long been a preventable blight to health. A part from occupational diseases t here are some hazards which will impair health of employees in industries. Workers in every Occupation are faced with a multitude of hazards in the work place. Ronald Blake has classified occupational hazards into the following four categories. The most pr essing environmental health problems today, in terms of death and illness worldwide are those associated with poor households and communities in the development countries. According to WHO and the World Bank, environmental improvement at the household and community level would make the greatest difference for global health. This Article also focuses on the lung disease mainly occurring du e to hazards caused by the patient occupation.

    2017-04-01

    Given the many different types of professionals working in public health and their diverse roles, it is likely that their information needs, information-seeking behaviors, and problem-solving abilities differ. Although public health professionals often work in interdisciplinary teams, few studies have explored their information needs and behaviors within the context of teamwork. This study explored the relationship between Canadian public health professionals' perceptions of their problem-solving abilities and their information-seeking behaviors with a specific focus on the use of evidence in practice settings. It also explored their perceptions of collaborative information seeking and the work contexts in which they sought information. Key Canadian contacts at public health organizations helped recruit study participants through their list-servs. An electronic survey was used to gather data about (a) individual information-seeking behaviors, (b) collaborative information-seeking behaviors, (c) use of evidence in practice environments, (d) perceived problem-solving abilities, and (e) demographic characteristics. Fifty-eight public health professionals were recruited, with different roles and representing most Canadian provinces and one territory. A significant relationship was found between perceived problem-solving abilities and collaborative information-seeking behavior (r = -.44, p public health professionals take a shared, active approach to problem solving, maintain personal control, and have confidence, they are more likely collaborate with others in seeking information to complete a work task. Administrators of public health organizations should promote collaboration by implementing effective communication and information-seeking strategies, and by providing information resources and retrieval tools. Public health professionals' perceived problem-solving abilities can influence how they collaborate in seeking information. Educators in public health

    Although the number of Japanese individuals traveling abroad has increased steadily, reaching approximately 17.3 million in 2007, the incidence of various travel-related health problems in Japan remains unknown. The travel-related health problems of Japanese travelers returning to Japan from abroad are analyzed by assessing the records. Data were collected retrospectively on returning travelers who visited the authors' travel clinic during the period from January 2005 through to December 2006 with any health problem acquired overseas. A total of 345 patients were included in this study (200 male, 145 female; average age, 34+/-12.3 years). Reasons for travel included leisure (45.8%); business (39.1%); visiting friends and relatives or accompanying other travelers (8.7%); volunteering (3.8%); and long stays in order to study or live (2.6%). The most visited destination was Asia (n=260), followed by Africa (n=105). The most commonly reported health problems were gastro-intestinal infections (39.1%), followed by respiratory tract infections (16.2%), animal bites (8.1%), and skin problems (5.8%). Together, malaria and dengue accounted for 10% of diagnoses in 125 febrile patients (36.2%). Although the profile of travel-related health problems in Japanese travelers is similar to that of Western travelers, the characteristics of travel were quite different. Therefore Japanese travel advice should be tailored to suit the Japanese traveler.

    2014-01-01

    Full Text Available We first introduce and analyze one multistep iterative algorithm by hybrid shrinking projection method for finding a solution of the system of generalized equilibria with constraints of several problems: the generalized mixed equilibrium problem, finitely many variational inclusions, the minimization problem for a convex and continuously Fréchet differentiable functional, and the fixed-point problem of an asymptotically strict pseudocontractive mapping in the intermediate sense in a real Hilbert space. We prove strong convergence theorem for the iterative algorithm under suitable conditions. On the other hand, we also propose another multistep iterative algorithm involving no shrinking projection method and derive its weak convergence under mild assumptions.

    When adolescents live with a parent with mental illness, they often partly take over the parental role. Little is known about the consequences of this so-called parentification on the adolescents' internalizing and externalizing problems. This survey study examined this effect cross-sectionally and longitudinally in a sample of 118 adolescents living with a parent suffering from mental health problems. In addition, the study examined a possible indirect effect via perceived stress. Path analyses were used to examine the direct associations between parentification and problem behavior as well as the indirect relations via perceived stress. The results showed that parentification was associated with both internalizing and externalizing problems cross-sectionally, but it predicted only internalizing problems 1 year later. An indirect effect of parentification on adolescent internalizing and externalizing problems via perceived stress was found, albeit only cross-sectionally. These findings imply that parentification can be stressful for adolescents who live with a parent with mental health problems, and that a greater awareness of parentification is needed to prevent adolescents from developing internalizing problems. © 2015 Family Process Institute.

    2017-07-01

    The number of migrants and refugees in Europe in the past few years has increased dramatically due to war, violence or prosecutions in their homeland. Migration may affect physical, mental and social health. The objective of this article is to assess migrants and refugees' health problems, and to recommend appropriate interventions. A PubMed search of published articles on health problems of newly arrived migrants and refugees was conducted from 2003 through 2016, focusing on the current refugee crisis in Europe. In addition to communicable diseases, such as respiratory, gastrointestinal and dermatologic infections, non-communicable diseases, including chronic conditions, mental and social problems, account for a significant morbidity burden in newly arrived migrants and refugees. Vaccine-preventable diseases are also of outmost importance. The appropriate management of newly arrived refugees and migrants' health problems is affected by barriers to access to health care including legal, communication, cultural and bureaucratic difficulties. There is diversity and lack of integration regarding health care provision across Europe due to policy differences between health care systems and social services. There is a notable burden of communicable and non-communicable diseases among newly arrived migrants and refugees. Provision of health care at reception and temporary centres should be integrated and provided by a multidisciplinary team Appropriate health care of migrants and refugees could greatly enhance their health and social status which will benefit also the host countries at large. © International Society of Travel Medicine, 2017.

    Concerns about health problems due to the increasing use of mobile phones are growing. Excessive use of mobile phones can affect the quality of sleep as one of the important issues in the health literature and general health of people. Therefore, this study investigated the relationship between the excessive use of mobile phones and general health and quality of sleep on 450 Occupational Health and Safety (OH&S) students in five universities of medical sciences in the North East of Iran in 2014. To achieve this objective, special questionnaires that included Cell Phone Overuse Scale, Pittsburgh's Sleep Quality Index (PSQI) and General Health Questionnaire (GHQ) were used, respectively. In addition to descriptive statistical methods, independent t-test, Pearson correlation, analysis of variance (ANOVA) and multiple regression tests were performed. The results revealed that half of the students had a poor level of sleep quality and most of them were considered unhealthy. The Pearson correlation co-efficient indicated a significant association between the excessive use of mobile phones and the total score of general health and the quality of sleep. In addition, the results of the multiple regression showed that the excessive use of mobile phones has a significant relationship between each of the four subscales of general health and the quality of sleep. Furthermore, the results of the multivariate regression indicated that the quality of sleep has a simultaneous effect on each of the four scales of the general health. Overall, a simultaneous study of the effects of the mobile phones on the quality of sleep and the general health could be considered as a trigger to employ some intervention programs to improve their general health status, quality of sleep and consequently educational performance.

  14. PowerPlay: Training an Increasingly General Problem Solver by Continually Searching for the Simplest Still Unsolvable Problem.

    Most of computer science focuses on automatically solving given computational problems. I focus on automatically inventing or discovering problems in a way inspired by the playful behavior of animals and humans, to train a more and more general problem solver from scratch in an unsupervised fashion. Consider the infinite set of all computable descriptions of tasks with possibly computable solutions. Given a general problem-solving architecture, at any given time, the novel algorithmic framework PowerPlay (Schmidhuber, 2011) searches the space of possible pairs of new tasks and modifications of the current problem solver, until it finds a more powerful problem solver that provably solves all previously learned tasks plus the new one, while the unmodified predecessor does not. Newly invented tasks may require to achieve a wow-effect by making previously learned skills more efficient such that they require less time and space. New skills may (partially) re-use previously learned skills. The greedy search of typical PowerPlay variants uses time-optimal program search to order candidate pairs of tasks and solver modifications by their conditional computational (time and space) complexity, given the stored experience so far. The new task and its corresponding task-solving skill are those first found and validated. This biases the search toward pairs that can be described compactly and validated quickly. The computational costs of validating new tasks need not grow with task repertoire size. Standard problem solver architectures of personal computers or neural networks tend to generalize by solving numerous tasks outside the self-invented training set; PowerPlay's ongoing search for novelty keeps breaking the generalization abilities of its present solver. This is related to Gödel's sequence of increasingly powerful formal theories based on adding formerly unprovable statements to the axioms without affecting previously provable theorems. The continually increasing

    To identify the predictors of self-reported confidence and skills of GPs in management of patients with mental health problems. Cross-sectional survey, with questionnaire presented to 246 GPs working in 62 practices throughout Gippsland. Rural general practices in Gippsland. One hundred and thirty-four GPs across Gippsland. GPs completed a questionnaire assessing self-perception of knowledge and skills in recognition and management of common mental health problems. Of 134 GPs, 45% reported that they have a specific interest in mental health, and 39% of GPs reported that they had previous mental health training. Only 22% of GPs describe having both an interest and prior training in mental health care. Age and years since graduation are not significantly related to self-reported confidence and skills. The results of this study highlight that self-professed interest and prior training in mental health are associated. Self-professed interest in mental health care predicts confidence and self-perceived skills in recognition, assessment and management of common mental health disorders. Similarly, prior training in mental health care predicts confidence and self-perceived skills in recognition, assessment and management of common mental health problems. Self-professed interest in mental health issues is also associated with hours of participation in continuing medical education related to mental health care. Unfortunately, only a minority described having both interest and prior training in mental health care.

    Although studies on the association of job dissatisfaction with mental health have been conducted in the past, few studies have dealt with the complicated links connecting job stress, job dissatisfaction, and stress-related illness. This study seeks to determine how job dissatisfaction is linked to common mental health issues. This study surveyed 3,172 civil servants (2,233 men and 939 women) in 1998, taking poor mental functioning, fatigue, and sleep disturbance as stress-related mental health problems. We examine how psychosocial risk factors at work and job dissatisfaction are associated independently with poor mental functioning, fatigue, and sleep disturbance after adjustment for other known risk factors, and how job dissatisfaction contributes to change in the degree of association between psychosocial risk factors at work and mental health problems. In general, psychosocial risk factors were independently associated with mental health problems. When adjusted for job dissatisfaction, not only was job satisfaction independently associated with mental health problems but it was also found that the association of psychosocial risk factors with mental health problems declined. Our results suggest that, although longitudinal research is necessary, attitudes toward satisfaction at work can potentially decrease the negative effects of psychosocial risk factors at work on mental health.

    To compare children with mental and physical health problems regarding (1) perceived disease severity; (2) the impact of their condition on their families; (3) their utilization of health care services (including satisfaction with care); and (4) parents' health literacy about their child's condition and its treatment. Furthermore, we examined whether parents' health literacy differs between types of mental health condition. Parental reports about their 9- to 14-year-old children with mental (n = 785) or physical health problems (n = 475) were analyzed from the population-based National Survey of Children with Special Health Care Needs in Switzerland. Mental health problems were perceived as being more severe (p mental health problem mentioned having a particular person or place to contact if they needed information or advice regarding the child's condition (p = 0.004) and were satisfied with the health care services their child received (p mental health problems vs. parents of children with physical health problems (OR in the adjusted model = 1.92; 95 % CI 1.47-2.50; p mental health problem (although only a trend was observable for internalizing problems). The large impact of children's mental health conditions on themselves and their families might be reduced by adapting the provision of health care and by increasing parents' health literacy.

    Postpartum mothers experience certain physical health conditions that may affect their quality of life, future health, and health of their children. Yet, the physical health of postpartum mothers is relatively neglected in both research and practice. The purpose of this review is to describe the general health status and prevalence of common physical health conditions of postpartum mothers. The review followed standard procedures for integrative literature reviews. Twenty-two articles were reviewed from searches in scientific databases, reference lists, and an up-to-date survey. Three tables were designed to answer review questions. In general, postpartum mothers self-rate their health as good. They experience certain physical conditions such as fatigue/physical exhaustion, sleep-related problems, pain, sex-related concerns, hemorrhoids/constipation, and breast problems. Despite a limited number of studies, the findings provide a glimpse of the presence of a number of physical health conditions experienced by women in the 2 years postpartum. In the articles reviewed, physical health conditions and postpartum period were poorly defined, no standard scales existed, and the administration of surveys varied widely in time. Those disparities prevented systematic comparisons of results and made it difficult to gain a coherent understanding of the physical health conditions of postpartum mothers. More longitudinal research is needed that focuses on the etiology, predictors, and management of the health conditions most prevalent among postpartum mothers. Instruments are needed that target a broader range of physical conditions in respect to type and severity.

    Nurses are suffering from increasing stress, and nursing is recognized as one of the most stressful job. Their mental health problems are serious and worthy of attention. The purpose of this study was to explore the relationship between resilience and mental health and general well-being among nurses. A cross-sectional survey was conducted in 2014, using a self-reported questionnaire. Participants were asked to complete the measure of resilience, mental health, and general well-being. The method of randomly cluster sampling was used to select nurses as participants. A survey of 365 nurses was conducted to test the hypothesized model. This study showed that resilience, mental health, and general well-being correlated with each other. General well-being was an effective predictor of resilience and mental health, whereas it both can moderate and mediate the relationship. Strategies to increase nurses' general well-being could enhance their resilience and reduce mental health problems. It is important to improve the mental health of nurses and maintain the professional values that ensure career sustainability. © 2017 John Wiley & Sons Australia, Ltd.

    A significant proportion of air travelers experience situational anxiety and physical health problems. Take-off and landing are assumed to be stressful, but anxiety related to other aspects of the air travel process, anxiety coping strategies, and in-flight health problems have not previously been investigated. We aimed to investigate frequency of perceived anxiety at procedural stages of air travel, individual strategies used to reduce such anxiety, and frequency of health problems on short-haul and long-haul flights. A questionnaire measuring the occurrence and frequency of the above was administered to two samples of intending travelers during a 3 month period to: (a) 138 travel agency clients, and (b) 100 individuals attending a hospital travel clinic. Of the 238 respondents, two thirds were women. Take-off and landing were a perceived source of anxiety for about 40% of respondents, flight delays for over 50%, and customs and baggage reclaim for a third of individuals. Most frequent anxiety-reduction methods included alcohol and cigarette use, and distraction or relaxation techniques. Physical health problems related to air travel were common, and there was a strong relationship between such problems and frequency of anxiety. Travel agency clients reported more anxiety but not more physical health symptoms overall than travel clinic clients. Women reported greater air-travel anxiety, and more somatic symptoms than men. Significant numbers of air travelers report perceived anxiety related to aspects of travel, and this is associated with health problems during flights. Airlines and travel companies could institute specific measures, including improved information and communication, to reassure clients and thereby diminish anxiety during stages of air-travel. Medical practitioners and travel agencies should also be aware of the potential stresses of air travel and the need for additional information and advice.

    1989-07-01

    This paper examines 3 major health-related issues: 1) existing health problems and illnesses resulting from physical environmental conditions at workplaces; 2) female workers' perception on illness and health protection; and 3) the relationship between illness and risk factors. The study area is textile factories in Bangkok and its peripheries. Data are drawn from the 1987 Survey of Occupational Health and Textile Industrial Development in Thailand: Effect on Health and Socioeconomics of Female Migrant Workers. This study shows that about 20% of female workers have ill-health problems and illness after a period of working mainly due to high levels of dust and noise, and inadequate light. These conditions are hazardous to the respiratory system (resulting in cough and chest tightness), the hearing system (pains as well as impaired and hearing loss), eye systems (irritation, reduced visual capacity) and skin allergy. Such illnesses are intensified in the long- run. The analysis of variances reveals that education, section of work, perception (particularly mask and ear plug) significantly affect these illnesses. This study concludes that health education and occupational health should be provided in factories with emphasis on health prevention and promotion.

    The general Spitzer-Haerm problem is unfolded through a redefinition of the dependent variable into two separate simpler problems. The first takes the form of a second order differential equation, and the second, that of an integration over the solution of the first problem, which provides the distribution function or, directly, the current and the heat flow. It is shown that the current and the heat flow can in general by synthesized from the solutions of the differential equation for two specific forms of the driving term. (author)

    2004-01-01

    The problem of two gravitational (or Coulombian) fixed centres is a classical integrable problem, stated and integrated by Euler in 1760. The integrability is due to the unexpected first integral G. We introduce some straightforward generalizations of the problem that still have the generalization of G as a first integral, but do not possess the energy integral. We present some numerical integrations showing the main features of their dynamics. In the domain of bounded orbits the behaviour of these a priori non-Hamiltonian systems is very similar to the behaviour of usual near-integrable systems

    The aim of this study was to describe strategies for recruiting participants into an intervention study that focused on improving problem-solving skills in caregivers of children with mental health problems. Caregivers of children with mental health problems report feeling physically and psychologically overwhelmed and have high rates of depression because of the demands of caregiving. Research on the needs of these caregivers and interventions to ameliorate their stress is needed. However, recruiting this population can be particularly difficult because of the stigma of mental illness. Available literature on recruitment of caregivers of persons with physical illness cannot be transferred to caregivers of children with mental health problems because of the different caregiving situations. There is a need to identify effective recruitment strategies to reduce cost and answer research questions. Clinical nurse specialists have the skills to facilitate the recruitment of research participants. We revised and expanded health system referrals, community outreach, and recruiting advertisement (ads). When these strategies did not increase recruitment, radio ads were used. The Andersen's Behavioral Model of Health Services Utilization was selected as a guiding framework. Radio ads were the most effective strategy for recruiting caregivers of children with mental health problems for this study. Recruitment was ultimately successful because we were flexible and made decisions consistent with the Andersen's Behavioral Model of Health Services Utilization. Clinical nurse specialists who study this population of caregivers should really consider the use of radio ads and systematically track which recruitment strategies lead to the greatest number of participants screened, eligible, and enrolled into studies.

    We present a practical branch and bound algorithm for globally solving generalized linear multiplicative programming problem with multiplicative constraints. To solve the problem, a relaxation programming problem which is equivalent to a linear programming is proposed by utilizing a new two-phase relaxation technique. In the algorithm, lower and upper bounds are simultaneously obtained by solving some linear relaxation programming problems. Global convergence has been proved and results of some sample examples and a small random experiment show that the proposed algorithm is feasible and efficient.

    Attending college can be a stressful time for many students. In addition to coping with academic pressure, some students have to deal with the stressful tasks of separation and individuation from their family of origin while some may have to attend to numerous work and family responsibilities. In this context, many college students experience the first onset of mental health and substance use problems or an exacerbation of their symptoms. Given the uniqueness of college students, there is a need to outline critical issues to consider when working with this population. In this commentary, first, the prevalence of psychiatric and substance use problems in college students and the significance of assessing age of onset of current psychopathology are described. Then, the concerning persistent nature of mental health problems among college students and its implications are summarized. Finally, important aspects of treatment to consider when treating college students with mental health problems are outlined, such as the importance of including parents in the treatment, communicating with other providers, and employing of technology to increase adherence. It is concluded that, by becoming familiar with the unique problems characteristic of the developmental stage and environment college students are in, practitioners will be able to better serve them.

    This paper calls for the routine integration of mental health promotion and prevention into UK General Practice in order to reduce the burden of mental and physical disorders and the ensuing pressure on General Practice. The proposals & the resulting document (https://ethicscharity.files.wordpress.com/2015/09/rcgp_keymsg_150925_v5.pdf) arise from an expert 'Think Tank' convened by the London Journal of Primary Care, Educational Trust for Health Improvement through Cognitive Strategies (ETHICS Foundation) and the Royal College of General Practitioners. It makes 12 recommendations for General Practice: (1) Mental health promotion and prevention are too important to wait. (2) Work with your community to map risk factors, resources and assets. (3) Good health care, medicine and best practice are biopsychosocial rather than purely physical. (4) Integrate mental health promotion and prevention into your daily work. (5) Boost resilience in your community through approaches such as community development. (6) Identify people at increased risk of mental disorder for support and screening. (7) Support early intervention for people of all ages with signs of illness. (8) Maintain your biopsychosocial skills. (9) Ensure good communication, interdisciplinary team working and inter-sectoral working with other staff, teams and agencies. (10) Lead by example, taking action to promote the resilience of the general practice workforce. (11) Ensure mental health is appropriately included in the strategic agenda for your 'cluster' of General Practices, at the Clinical Commissioning Groups, and the Health and Wellbeing Board. (12) Be aware of national mental health strategies and localise them, including action to destigmatise mental illness within the context of community development.

  20. Two Efficient Generalized Laguerre Spectral Algorithms for Fractional Initial Value Problems

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available We present a direct solution technique for approximating linear multiterm fractional differential equations (FDEs on semi-infinite interval, using generalized Laguerre polynomials. We derive the operational matrix of Caputo fractional derivative of the generalized Laguerre polynomials which is applied together with generalized Laguerre tau approximation for implementing a spectral solution of linear multiterm FDEs on semi-infinite interval subject to initial conditions. The generalized Laguerre pseudo-spectral approximation based on the generalized Laguerre operational matrix is investigated to reduce the nonlinear multiterm FDEs and its initial conditions to nonlinear algebraic system, thus greatly simplifying the problem. Through several numerical examples, we confirm the accuracy and performance of the proposed spectral algorithms. Indeed, the methods yield accurate results, and the exact solutions are achieved for some tested problems.

    Eigenvalue problems are ubiquitous in computer vision, covering a very broad spectrum of applications ranging from estimation problems in multi-view geometry to image segmentation. Few other linear algebra problems have a more mature set of numerical routines available and many computer vision libraries leverage such tools extensively. However, the ability to call the underlying solver only as a "black box" can often become restrictive. Many 'human in the loop' settings in vision frequently exploit supervision from an expert, to the extent that the user can be considered a subroutine in the overall system. In other cases, there is additional domain knowledge, side or even partial information that one may want to incorporate within the formulation. In general, regularizing a (generalized) eigenvalue problem with such side information remains difficult. Motivated by these needs, this paper presents an optimization scheme to solve generalized eigenvalue problems (GEP) involving a (nonsmooth) regularizer. We start from an alternative formulation of GEP where the feasibility set of the model involves the Stiefel manifold. The core of this paper presents an end to end stochastic optimization scheme for the resultant problem. We show how this general algorithm enables improved statistical analysis of brain imaging data where the regularizer is derived from other 'views' of the disease pathology, involving clinical measurements and other image-derived representations.

  2. The association between childhood autistic traits and adolescent psychotic experiences is explained by general neuropsychiatric problems.

    Studies suggest associations between childhood autistic traits and adolescent psychotic experiences. However, recent research suggests that a general neuropsychiatric problems factor predicts adverse outcomes better than specific diagnostic entities. To examine if the alleged association between autistic traits and psychotic experiences could rather be explained by a general neuropsychiatric problems factor comprising symptoms of ADHD, tic disorder, developmental coordination disorder, and learning disorder, we conducted a prospective cohort study based on the Child and Adolescent Twin Study in Sweden. In addition, we examined the genetic and environmental influences on the associations. A total of 9,282 twins with data on childhood autistic traits and other neuropsychiatric problems, and follow-up data on psychotic experiences at ages 15 and/or 18 years were included. First, psychotic experiences were regressed on autistic traits and second, the general neuropsychiatric problems factor was added to the model. Auditory hallucinations were analyzed separately from the other psychotic experiences. Finally, twin analyses were employed to disentangle genetic from environmental influences in the observed associations. Replicating prior research, significant associations were found between autistic traits in childhood and auditory hallucinations at ages 15 and 18. However, after controlling for the general neuropsychiatric problems factor, the associations between autistic traits and auditory hallucinations disappeared, whereas the association between the general neuropsychiatric problems factor and auditory hallucinations persisted after controlling for autistic traits. Twin analyses revealed that the association between the general neuropsychiatric problems factor and auditory hallucinations was driven by shared genetic influences. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    Functional constipation (FC) is a significant health problem in children and contrary to common belief, has serious ramifications on the lives of children and their families. It is defined by the Rome criteria which encourage the use of multiple clinical features for diagnosis. FC in children has a high prevalence (0.7%-29%) worldwide, both in developed and developing countries. Biopsychosocial risk factors such as psychological stress, poor dietary habits, obesity and child maltreatment are commonly identified predisposing factors for FC. FC poses a significant healthcare burden on the already overstretched health budgets of many countries in terms of out-patient care, in-patient care, expenditure for investigations and prescriptions. Complications are common and range from minor psychological disturbances, to lower health-related quality of life. FC in children also has a significant impact on families. Many paediatric clinical trials have poor methodological quality, and drugs proved to be useful in adults, are not effective in relieving symptoms in children. A significant proportion of inadequately treated children have similar symptoms as adults. These factors show that constipation is an increasing public health problem across the world with a significant medical, social and economic impact. This article highlights the potential public health impact of FC and the possibility of overcoming this problem by concentrating on modifiable risk factors rather than expending resources on high cost investigations and therapeutic modalities.

    Arroyo-Cobo, J M

    2011-01-01

    A review was carried out of scientific literature on health care strategies for mental health problems in the prison environment. Data is given about the main activities put into practice by prison administrations as a response to the worrying information that has come to light in recent epidemiological studies on mental disorders in prison, with figures that, when compared to the general population, give results of double the number of cases of Common Mental Illness (CMI) and four times the number of cases of Severe Mental Illness (SMI) amongst prison inmates. A review was made of the most important bibliographical databases containing health care policies for mental health problems in prison published by prison administrations in the last 10 years. This information was completed with other data obtained from an analysis of the indicators available in Health Care Coordination on its health care strategies for mental health in centres run by the Secretary General of Prisons, in Spain. There is little in the way of scientific literature that clearly states health care policies for mental illness in the prison environment. Those that do tend to agree with a number of affirmations that include the obligation to offer a therapeutic response of equal quality to that received by patients in the community, the need for a multi-disciplinary team responsible for caring for this type of patient, along with a coordinated effort between the medical, social, legal and prison administrations that at a given time have to care for them.

    Full Text Available The aims of the present multi-center study were to investigate the extent of mental health problems in adolescents with a hearing loss and cochlear implants (CIs in comparison to normal hearing (NH peers and to investigate possible relations between the extent of mental health problems of young CI users and hearing variables, such as age at implantation, or functional gain of CI. The survey included 140 adolescents with CI (mean age = 14.7, SD = 1.5 years and 140 NH adolescents (mean age = 14.8, SD = 1.4 years, their parents and teachers. Participants were matched by age, gender and social background. Within the CI group, 35 adolescents were identified as risk cases due to possible and manifest additional handicaps, and 11 adolescents were non-classifiable. Mental health problems were assessed with the Strengths and Difficulties Questionnaire (SDQ in the versions Self, Parent, and Teacher. The CI group showed significantly more Peer Problems than the NH group. When the CI group was split into a risk-group (35 risk cases and 11 non-classifiable persons and a non-risk group (n = 94, increased peer problems were perceived in both CI subgroups by adolescents themselves. However, no further differences between the CI non-risk group and the NH group were observed in any rater. The CI-risk group showed significantly more hyperactivity compared to the NH group and more hyperactivity and conduct problems compared to the CI non-risk group. Cluster analyses confirmed that there were significantly more adolescents with high problems in the CI-risk group compared to the CI non-risk group and the NH group. Adolescents with CI, who were able to understand speech in noise had significantly less difficulties compared to constricted CI users. Parents, teachers, and clinicians should be aware that CI users with additionally special needs may have mental health problems. However, peer problems were also experienced by CI adolescents without additional handicaps

  8. Violence in Mexico: A social or public health problem?

    Science.gov (United States)

    Casas Patiño, Donovan; Rodríguez Torres, Alejandra; Salazar Morales, Mario Rodolfo

    2016-03-08

    This article seeks to explain the importance of violence as a social phenomenon and public health, trying to envision this issue not only from a curative approach to health, but from the social determinants of health, such as economics, politics and the administration of justice. Here, the younger population lacks real opportunities with an “absent State” that fails to provide structure. These frameworks play a fundamental role in the manifestation of violence. Thus, the debate for addressing and resolving violence opens the way to new perspectives regarding social factors as part of a public health, which cannot be oblivious to the state of the collective. Thus, the analysis of this situation shows that we cannot keep overlooking the whole picture of the real problem in the social health of our world instead of focusing on its discordant parts.

    The most extensive and detailed study of the health effects of a nuclear attack on a major urban centre has been recently made of London. Not only hospitals, physicians, nurses, all other health professionals and technicians would be in short supply, but antibiotics, parenteral fluids, bandages, surgical equipment and all the sophisticated medical technology would be similarly lacking. Disrupting of communications, locally and nationally, would contribute to the general chaos following a nuclear attack. 13 refs, 2 tabs

    2012-05-01

    This cross-sectional study estimated the prevalence of work days lost due to health problems and associated factors among industrial workers. The study population was a simple random cluster sample of 3,403 workers from 16 to 65 years of age in the city of Salvador, Bahia State, Brazil. Data were collected with individual home interviews. Among industrial workers, one-year prevalence of work days lost to health problems was 12.5%, of which 5.5% were directly work-related and 4.1% aggravated by work. There were no statistically significant differences when compared to other worker categories. Self-perceived workplace hazards, history of work-related injury, and poor self-rated health were associated with work days lost due to work-related injuries/diseases. The findings showed that work days lost are common among both industrial and non-industrial workers, thereby affecting productivity and requiring prevention programs.

  17. The problem of general Radon representation for an arbitrary Hausdorff space

    1999-10-01

    After the fundamental work of Riesz, Radon and Hausdorff in the period 1909-1914, the following problem of general Radon representation emerged: for any Hausdorff space find the space of linear functionals that are integrally representable by Radon measures. In the early 1950s, a partial solution of this problem (the bijective version) for locally compact spaces was obtained by Halmos, Hewitt, Edwards, Bourbaki and others. For bounded Radon measures on a Tychonoff space, the problem of isomorphic Radon representation was solved in 1956 by Prokhorov. In this paper we give a possible solution of the problem of general Radon representation. To do this, we use the family of metasemicontinuous functions with compact support and the class of thin functionals. We present bijective and isomorphic versions of the solution (Theorems 1 and 2 of §2.5). To get the isomorphic version, we introduce the family of Radon bimeasures.

    After the fundamental work of Riesz, Radon and Hausdorff in the period 1909-1914, the following problem of general Radon representation emerged: for any Hausdorff space find the space of linear functionals that are integrally representable by Radon measures. In the early 1950s, a partial solution of this problem (the bijective version) for locally compact spaces was obtained by Halmos, Hewitt, Edwards, Bourbaki and others. For bounded Radon measures on a Tychonoff space, the problem of isomorphic Radon representation was solved in 1956 by Prokhorov. In this paper we give a possible solution of the problem of general Radon representation. To do this, we use the family of metasemicontinuous functions with compact support and the class of thin functionals. We present bijective and isomorphic versions of the solution (Theorems 1 and 2 of paragraph 2.5). To get the isomorphic version, we introduce the family of Radon bimeasures.

    This research has focused on a parallelization of the mathematical library for a generalized eigenvalue problem for real band matrices on IBM SP and Hitachi SR2201. The origin of the library is LASO (Lanczos Algorithm with Selective Orthogonalization), which was developed on the basis of Block Lanczos method for standard eigenvalue problem for real band matrices at Texas University. We adopted D.O.F. (Degree Of Freedom) decomposition method for a parallelization of this library, and evaluated its parallel performance. (author)

    Left ventricular assist devices (LVADs) are increasingly used to treat patients with end-stage heart failure. These patients may develop acute noncardiac surgical problems around the time of LVAD implantation or, as survival continues to improve, chronic surgical problems as ambulatory patients remote from the LVAD implant. Previous reports of noncardiac surgical problems in LVAD patients included patients with older, first-generation devices and do not address newer, second-generation devices. We describe the frequency and management of noncardiac surgical problems encountered during LVAD support with these newer-generation devices to assist noncardiac surgeons involved in the care of patients with LVADs. We retrospectively reviewed the medical records of consecutive patients receiving LVADs at our institution. We collected data for any consultation by noncardiac surgeons within the scope of general surgery during LVAD support and subsequent treatment. Ninety-nine patients received implantable LVADs between 2003 and 2009 (first-generation, n = 19; second-generation, n = 80). Excluding intestinal hemorrhage, general surgical opinions were rendered for 34 patients with 49 problems, mostly in the acute recovery phase after LVAD implantation. Of those, 27 patients underwent 28 operations. Respiratory failure and intra-abdominal pathologies were the most common problems addressed, and LVAD rarely precluded operation. Patients with second-generation LVADs were more likely to survive hospitalization (P = .04) and develop chronic, rather than emergent, surgical problems. Patients with LVADs frequently require consultation from noncardiac surgeons within the scope of general surgeons and often require operation. Patients with second-generation LVADs are more likely to become outpatients and develop more elective surgical problems. Noncardiac surgeons will be increasingly involved in caring for patients with LVADs and should anticipate the problems unique to this patient

  3. Bioarcheology has a "health" problem: conceptualizing "stress" and "health" in bioarcheological research.

    Temple, Daniel H; Goodman, Alan H

    2014-10-01

    This article provides a critical historical overview of the stress concept in bioarcheological research and critically evaluates the term "health" in reference to skeletal samples. Stress has a considerable history in 20th century physiological research, and the term has reached a critical capacity of meaning. Stress was operationalized around a series of generalized physiological responses that were associated with a deviation from homeostasis. The term was incorporated into anthropological research during the mid-20th century, and further defined in bioarcheological context around a series of skeletal indicators of physiological disruption and disease. Emphases on stress became a predominate area of research in bioarcheology, and eventually, many studies utilized the terms "health" and "stress" interchangeably as part of a broader, problem-oriented approach to evaluating prehistoric population dynamics. Use of the term "health" in relation to skeletal samples is associated with the intellectual history of bioarcheological research, specifically influences from cultural ecology and processualist archeology and remains problematic for two reasons. First, health represents a comprehensive state of well-being that includes physiological status and individual perception, factors that cannot be readily observed in skeletal samples. Second, the categorization of populations into relative levels of health represents a typological approach, however unintentional. This article advocates for the integration of methodological and theoretical advances from human biology and primatology, while simultaneously incorporating the theoretical constructs associated with social epidemiology into bioarcheological research. Such an approach will significantly increase the applicability of bioarcheological findings to anthropological and evolutionary research, and help realize the goal of a truly relevant bioarcheological paradigm.

    This paper describes gambling problems among Ontario students in 2009 and examines the relationship between gambling problems and substance use problems, mental health problem indicators, and delinquent behaviors. Data were derived from the Ontario Student Drug Use and Health Survey of Ontario students in grades 7-12. Gambling problems were measured as 2 or more of 6 indicators of problem gambling. In total 2.8% of the students surveyed endorsed two or more of the problem gambling items. The odds of problem gamblers reporting mental distress was 4.2 times higher than the rest of the sample and the odds of problem gamblers reporting a suicide attempt were 17.8 times greater than the rest of the sample. In addition compared to the rest of the students, delinquent behaviors were also more common among problem gamblers, including theft (OR = 14.5), selling marijuana (OR = 19.6), gang fights (OR = 11.3) and carrying a handgun (OR = 11.2). In a multivariate analysis, substance-use problems, mental health problems, and the participation in a variety of delinquent behaviors remained significantly associated with youth problem gambling behavior. Students who report problem gambling behaviors show increased substance abuse, mental health, and delinquency/criminal problems that are similar to those seen among adult problem gamblers. The association between these problems suggests that these problems could be addressed in a unified manner.

    We propose a Generalized Pattern Search (GPS) method to solve a class of nonsmooth minimization problems, where the set of nondifferentiability is included in the union of known hyperplanes and, therefore, is highly structured. Both unconstrained and linearly constrained problems are considered. At each iteration the set of poll directions is enforced to conform to the geometry of both the nondifferentiability set and the boundary of the feasible region, near the current iterate. This is the key issue to guarantee the convergence of certain subsequences of iterates to points which satisfy first-order optimality conditions. Numerical experiments on some classical problems validate the method.

    We study Green's functions of the generalized Sturm-Liouville problems that are related to each other by Darboux -equivalently, supersymmetrical - transformations. We establish an explicit relation between the corresponding Green's functions and derive a simple formula for their trace. The class of equations considered here includes the conventional Schroedinger equation and generalizations, such as for position-dependent mass and with linearly energy-dependent potential, as well as the stationary Fokker-Planck equation.

    Binns, Colin W; Lee, Mi Kyung; Lee, Andy H

    2018-04-01

    Dietary supplements are a global business worth more than US$100 billion annually. These supplements are taken by up to 50% of adults and perhaps one-third of children in economically advanced economies. Definitions of dietary supplements differ from country to country, and regulation is generally lax and often seems to be directed more toward promoting commerce than protecting public health. Supplements may directly cause toxic reactions or may interact with other supplements or pharmaceuticals. Some supplements are found to have been contaminated with heavy metals, and others do not contain the expected quantities of active ingredients. In general, supplements are not needed except in cases of established deficiencies, and excess of some nutrients can increase cancer rates. There are important public health reasons for taking some supplements, including folate and iodine in pregnancy. This review discusses the public health concerns associated with dietary supplements and suggests directions for further regulation.

    Shen, Peiping; Zhang, Tongli; Wang, Chunfeng

    2017-01-01

    This article presents a new approximation algorithm for globally solving a class of generalized fractional programming problems (P) whose objective functions are defined as an appropriate composition of ratios of affine functions. To solve this problem, the algorithm solves an equivalent optimization problem (Q) via an exploration of a suitably defined nonuniform grid. The main work of the algorithm involves checking the feasibility of linear programs associated with the interesting grid points. It is proved that the proposed algorithm is a fully polynomial time approximation scheme as the ratio terms are fixed in the objective function to problem (P), based on the computational complexity result. In contrast to existing results in literature, the algorithm does not require the assumptions on quasi-concavity or low-rank of the objective function to problem (P). Numerical results are given to illustrate the feasibility and effectiveness of the proposed algorithm.

    This was to study children with early detected externalising behaviour problems compared to matched controls regarding oral health, oral health risk behaviour and the parental evaluation of the child's oral health and dental care. Children aged 10-13 years and with externalising behaviour problems, were compared to matched controls. Behavioural characteristics were based on the Strength and Difficulties Questionnaire. The children and their parents completed questionnaires regarding dental fear, tooth brushing, dietary habits and evaluation of oral health and dental care. Data on dental caries risk assessments, caries, behaviour management problems and dental trauma were obtained from dental files. There were no differences in caries prevalence in children with early detected externalising behaviour problems, compared to controls. However, the former group consumed more sweet drinks when thirsty and brushed their teeth fewer than twice daily; they also had more dental trauma in both dentitions and a higher risk range for dental fear, compared to controls. This study points out potential oral health risk factors in children with early-detected externalising behaviour problems. Although no difference in caries prevalence was observed, externalising behaviour may affect oral health. Therefore, dental professionals should support the families and the children to preserve dental health by offering increased prophylactic measures. There were no differences between children with externalising behaviour problems, compared with controls, regarding the parent evaluation of their child's dental health. However, more parents in the study group evaluated the dental care as poor or not functioning.

  13. Commentary: getting real on addressing health care disparities and other systems problems.

    Physician membership organizations vary in the extent of their engagement in activities to address health disparities. Increasing engagement of those organizations not already highly active in this critical area is, thus, an opportunity. Studies that provide definitional contours of key issues, like disparities, are necessary and must be iteratively refined. However, parallel activities of intervention with measured outcomes to assess the effects of these interventions are necessary to truly address major problems in the health care system. To date, work in the problem definition category exceeds work toward intervention in and mitigation of these problems with measured outcomes. Many problems in health care, including disparities, are now sufficiently understood that it is time to shift focus toward bold intervention with measured outcomes. Optimal approaches that yield superior outcomes generally require collaboration across the provider-payer spectrum and the private sectors, including physicians, hospitals, insurers, etc. Stakeholders are now free to act in such coordinated fashion; it only requires social capital that permits cooperation and compromise. Interventions for problems such as health care disparities can be developed in the private sector and mirrored by government payers if physicians and organizations can get real about collaborating to implement outcomes-based initiatives to improve the health of all patients.

The cognitive domains examined were general cognitive ability and executive abilities.Methods: Three different clinical samples of pupils with school problems were analyzed to assess their cognitive Wechsler Intelligence Scale for Children profiles. In particular, the general cognitive ability index and the executive markers (ie, verbal memory index and processing speed index were of interest. Of the total sample (n = 198, two main groups were contrasted; one met the full criteria for attention deficit hyperactivity disorder (ADHD/subthreshold ADHD, and one was comprised of those with milder attention problems, insufficient to meet the criteria for ADHD/subthreshold ADHD.Results: It could be demonstrated that both groups had a significantly higher score on the general cognitive ability index than on measures of working memory and processing speed. This difference was more pronounced for boys.Conclusion: These types of cognitive differences need to be considered in children with different kinds of learning, behavior, and attention problems; this is also true for children presenting with an average general intelligence quotient and with milder attention problems. Current educational expectations are demanding for children with mild difficulties, and such cognitive information will add to the understanding of the child's learning problems, hopefully leading to a better adapted education than that conventionally available.Keywords: working memory, processing speed, children, learning and

    Reported health hazards from video display units (VDUs) vary from headaches to miscarriage and there is some concern that health problems experienced by VDU users could be associated with extra-low-frequency (ELF) electromagnetic field emissions. While investigating an individual case of 'VDU Syndrome' a procedure was developed which could be used to investigate and evaluate other complaints of a similar type. A relationship between the number of hours monitor work and severity of symptoms was observed along with a cyclic nature to the operator's sensitivity to VDU work. (author)

    The assessment of health effects from low-level exposure to radiation is a matter of considerable controversy. Existing standards for exposure are based primarily on estimates of health effects obtained by extrapolation from effects of high-level exposures such as those experienced at Hiroshima and Nagasaki. Occupational and environmental exposures provide one source of data for this task. A number of studies of populations exposed in this manner have attracted recent attention. Because of the size of most of the groups and the magnitude of the exposures received, the amount that can be learned from such populations is severely limited. A number of the problems involved in analyzing and interpreting such data are addressed. Many of these problems are illustrated by a current study of the effects on mortality of occupational exposure to radiation at the Hanford plant

    Problem-based learning (PBL) has been adopted by many medical schools in North America. Because problem solving, information seeking, and lifelong learning skills are central to the PBL curriculum, health sciences librarians have been actively involved in the PBL process at these medical schools. The introduction of PBL in a library and information science curriculum may be appropriate to consider at this time. PBL techniques have been incorporated into a health sciences librarianship course at the School of Library and Information Science (LIS) at the University of Wisconsin-Milwaukee to explore the use of this method in an advanced Library and Information Science course. After completion of the course, the use of PBL has been evaluated by the students and the instructor. The modified PBL course design is presented and the perceptions of the students and the instructor are discussed. PMID:9681169

    There has been recent controversy about whether aid directed specifically to health has caused recipient governments to reallocate their own funds to non-health areas. At the same time, general budget support (GBS) has been increasing. GBS allows governments to set their own priorities, but little is known about how these additional resources are subsequently used. This paper uses cross-country panel data to assess the impact of GBS programmes on health spending in low-income and middle-income countries, using dynamic panel techniques to estimate unbiased coefficients in the presence of serial correlation. We found no clear evidence that GBS had any impact, positive or negative, on government health spending derived from domestic sources. GBS also had no observed impact on total government health spending from all sources (external as well as domestic). In contrast, health-specific aid was associated with a decline in health expenditures from domestic sources, but there was not a full substitution effect. That is, despite this observed fungibility, health-specific aid still increases total government health spending from all sources. Finally, increases in total government expenditure led to substantial increases in domestic government health expenditures. Copyright © 2012 John Wiley & Sons, Ltd.

    Background and aims Relatively little is known about co-occurring gambling problems and their overlap with other addictive behaviors among individuals attending mental health services. We aimed to determine rates of gambling and substance use problems in patients accessing mental health services in Victoria, Australia. Methods A total of 837 adult patients were surveyed about their gambling and administered standardized screening tools for problem gambling and harmful tobacco, alcohol, and drug use. Prevalence of gambling problems was estimated and regression models used to determine predictors of problem gambling. Results The gambling participation rate was 41.6% [95% CI = 38.2-44.9]. The Problem Gambling Severity Index identified 19.7% [CI = 17.0-22.4] as "non-problem gamblers," 7.2% [CI = 5.4-8.9] as "low-risk" gamblers, 8.4% [CI = 6.5-10.2] as "moderate-risk" gamblers, and 6.3% [CI = 4.7-8.0] as "problem gamblers." One-fifth (21.9%) of the sample and 52.6% of all gamblers were identified as either low-risk, moderate-risk, or problem gamblers (PGs). Patients classified as problem and moderate-risk gamblers had significantly elevated rates of nicotine and illicit drug dependence (p gambling. Discussion and conclusions Patients were less likely to gamble, but eight times as likely to be classified as PG, relative to Victoria's adult general population. Elevated rates of harmful substance use among moderate-risk and PG suggest overlapping vulnerability to addictive behaviors. These findings suggest mental health services should embed routine screening into clinical practice, and train clinicians in the management of problem gambling.

    Since 2013, Georgia enacted Universal Healthcare (UHC) program. Inclusion of uninsured population in the UHC program will have a positive impact on their financial accessibility to the health services. The study aims to analyze the referral rate of the beneficiaries to the health service providers before introduction and after application of the UHC program, particularly, how much it increased the recently uninsured population referral to primary health care units, and also to study the level of satisfaction with the UHC program. Research was conducted by qualitative and quantitative methods. The target groups' (program beneficiaries, physicians, personnel of the Social Service Agency) opinions were identified by means of face-to-face interviews. Enactment of the UHC programs significantly raised the population refferal to the family physicians, and the specialists. Insignificantly, but also increased the frequency of laboratory and diagnostic services. Despite the serious positive changes caused by UHC program implementation there still remain the problems in the primary healthcare system. Also, it is desirable to raise the financial availability of those medical services, which may cause catastrophic costs. In this respect, such medical services must be involved in the universal healthcare program and been expanded their scale. For the purpose of effective usage of the limited funds allocated for health care services provision, the private health insurance companies should be involved in UHC programs. This, together with the reduction of health care costs will increase a competition in the medical market, and enhance the quality of health service.

    Afghanistan has been ravaged by years of conflict. To provide emergency services and restore access health services, the Public Health Ministry with the assistance of partners developed first a package of basic health services delivered by NGO contractors and second a package of essential hospital services. The Ministry's role consists of providing guidance. To reduce the many issues and problems affecting this role, reforms are now being undertaken and a new national health care strategy is being developed within the framework of the National Development Strategy. An institution-building project has been initiated with European Union funding to allow the Health Ministry to carry out its stewardship and management functions with greater effectiveness and transparency. This project is essential for the successful outcome of all future strategies and programs planned by the Health Ministry to enhance its institutional effectiveness. The objectives of this project are to strengthen planning and auditing activities, promote quality assurance, implement funding mechanisms for health-related activities, organize management of human resources, maintain ongoing efforts to reform the administration and fight against corruption, and lay the foundations for managing finances and procurement. The scope of this project underlines the importance of its outcome. However the institution-building process will be long and constantly threatened by political instability and insecurity.

  4. Variational P1 approximations of general-geometry multigroup transport problems

    International Nuclear Information System (INIS)

    1995-01-01

    A variational approximation is developed for general-geometry multigroup transport problems with arbitrary anisotropic scattering. The variational principle is based on a functional that approximates a reaction rate in a subdomain of the system. In principle, approximations that result from this functional ''optimally'' determine such reaction rates. The functional contains an arbitrary parameter α and requires the approximate solutions of a forward and an adjoint transport problem. If the basis functions for the forward and adjoint solutions are chosen to be linear functions of the angular variable Ω, the functional yields the familiar multigroup P 1 equations for all values of α. However, the boundary conditions that result from the functional depend on α. In particular, for problems with vacuum boundaries, one obtains the conventional mixed boundary condition, but with an extrapolation distance that depends continuously on α. The choice α = 0 yields a generalization of boundary conditions derived earlier by Federighi and Pomraning for a more limited class of problems. The choice α = 1 yields a generalization of boundary conditions derived previously by Davis for monoenergetic problems. Other boundary conditions are obtained by choosing different values of α. The authors discuss this indeterminancy of α in conjunction with numerical experiments

    Full Text Available The Problem-Based Learning (Problem-Based Learning - PBL has been recognized worldwide as an approach to promote the acquisition of knowledge by students at the same time that helps them develop skills and professional attitudes desirable. Unlike the conventional methods of teaching that use of application problems after the theory was presented, the PBL uses a problem to start, focus and motivate the learning of new concepts 13. In this approach, the student uses different mental processes, such as ability to raise hypotheses, compare, analyze, interpret, and evaluate and develop the ability to take responsibility for their education 11.12. The methodology of PBL has been a valuable tool in shaping the health care professional, with advantages over the traditional method of teaching. However, for its deployment there is a need for considerable institutional effort. Are necessary adjustments, including changes in the way of evaluation, for changes in mindset about the role of teachers in the process teaching / learning, investment in infrastructure, adaptations of the environment, improvement of libraries and other 19,20,21, 22. The process of change in education will bring many challenges, such as a break with traditional models of education and train health professionals with skills to recover the essential dimension of care: the relationship between humans.

  13. Generalization of the Fourier Convergence Analysis in the Neutron Diffusion Eigenvalue Problem

    International Nuclear Information System (INIS)

    2005-01-01

    Fourier error analysis has been a standard technique for the stability and convergence analysis of linear and nonlinear iterative methods. Lee et al proposed new 2- D/1-D coupling methods and demonstrated several advantages of the new methods by performing a Fourier convergence analysis of the methods as well as two existing methods for a fixed source problem. We demonstrated the Fourier convergence analysis of one of the 2-D/1-D coupling methods applied to a neutron diffusion eigenvalue problem. However, the technique cannot be used directly to analyze the convergence of the other 2-D/1-D coupling methods since some algorithm-specific features were used in our previous study. In this paper we generalized the Fourier convergence analysis technique proposed and analyzed the convergence of the 2-D/1-D coupling methods applied to a neutron diffusion Eigenvalue problem using the generalized technique

    Full Text Available Abstract Background Throughout the economic and political reforms in post-communist countries, significant changes have also occurred in public morality. One of the tasks of the Lithuanian health policy is to create mechanisms for strengthening the significance of ethical considerations in the decision-making processes concerning health care of individuals and groups of individuals, as well as considering the positions of physicians and the health care system itself in a general way. Thus, health care ethics could be analyzed at two levels: the micro level (the ethics of doctor-patient relationships and the macro level (the ethics of health policy-making, which can be realized by applying the principles of equal access, reasonable quality, affordable care and shared responsibilities. To date, the first level remains dominant, but the need arises for our attention to refocus now from the micro level to the patterns of managing and delivering care, managing the health care resources, and conducting business practices. Discussion In attempting to increase the efficiency of health services in Lithuania, a common strategy has been in place for the last fifteen years. Decentralization and privatization have been implemented as part of its policy to achieve greater efficiency. Although decentralization in theory is supposed to improve efficiency, in practice the reform of decentralization has still to be completely implemented in Lithuania.

    High rates of imprisonment among American men and women have motivated recent research on the well-being of children of incarcerated parents. Despite advances in the literature, little is known regarding the mental health status of children who experience maternal relative to paternal incarceration. Accordingly, we examine whether there are differences in mental health needs among children of incarcerated parents. Specifically, we assess whether incarcerated mothers are more likely than incarcerated fathers to report that their children suffer from mental health problems. Using cross-sectional data on children (N = 1,221) compiled from a sample of parents confined in the Arizona Department of Corrections, we find that children of incarcerated mothers are significantly more likely to be identified as suffering from mental health problems. This effect remained even after controlling for additional parent stressors and child risk factors such as exposure to violence, in utero exposure to drugs/alcohol, and parental mental illness. Policy implications and directions for future research are discussed.

    Full Text Available This study explored the health problems of never-married women as they relate to modern social life. In-depth interviews were conducted with a purposive sample of 45 never-married women aged 30–50 working or living in Bangkok and having health problems. It was found that never-married women in this modern era have experienced a variety of illnesses, such as “office syndrome” symptoms, chronic illnesses, and psychological and psychosomatic symptoms. Their social life resulted from the response to the context of modernity and was made through careful thought and deliberation. Whichever choice of social life they make, the consequences may lead them to a state of illness, distress, anxiety, and paranoia. These choices involve work, living conditions/environments, and intimacy aspects of their modern social life. This is the result of procuring by “husky modernity” which seems to be merely a “husk” or superficial modernization and changes so rapidly, but there is no core and it is full of double standards of traditional and new norms that have mixed together and fight against each other. Supporting health-related knowledge and information exchange within the network coupled with experience sharing essential for living in the modern society will enable them to sensibly decide on a path to good health.

  20. Management of common behaviour and mental health problems.

    Science.gov (United States)

    El-Radhi, A Sahib

    Behavioural problems are usually influenced by both biological and environmental factors. Disruptive behavioural problems such temper tantrums or attention deficit hyperactivity disorder are displayed during the first years of childhood. Breath-holding attacks are relatively common and are an important problem. Although the attacks are not serious and the prognosis is usually good, parents often fear that their child may die during an attack. Parents therefore require explanation and reassurance from health professionals. Conduct disorders (often referred to as antisocial behaviours), such as aggression to others or theft, are more serious as they tend to be repetitive and persistent behaviours where the basic rights of others are violated. Emotional problems, such as anxiety, depression and post-traumatic stress disorder tend to occur in later childhood, and are often unrecognised because young children often find it difficult to express their emotions, or it may go unnoticed by the child's parents. This article briefly discusses the most common behavioural problems, including autism, that affect children of all ages.

    Cell phones use electromagnetic, nonionizing radiations in the microwave range, which some believe may be harmful to human health. The present study aimed to determine the effect of electromagnetic radiations (EMRs) on unstimulated/stimulated salivary flow rate and other health-related problems between the general populations residing in proximity to and far away from mobile phone base stations. A total of four mobile base stations were randomly selected from four zones of Jaipur, Rajasthan, India. Twenty individuals who were residing in proximity to the selected mobile phone towers were taken as the case group and the other 20 individuals (control group) who were living nearly 1 km away in the periphery were selected for salivary analysis. Questions related to sleep disturbances were measured using Pittsburgh Sleep Quality Index (PSQI) and other health problems were included in the questionnaire. Chi-square test was used for statistical analysis. It was unveiled that a majority of the subjects who were residing near the mobile base station complained of sleep disturbances, headache, dizziness, irritability, concentration difficulties, and hypertension. A majority of the study subjects had significantly lesser stimulated salivary secretion (P base stations on the health and well-being of the general population cannot be ruled out. Further studies are warranted to evaluate the effect of electromagnetic fields (EMFs) on general health and more specifically on oral health.

  2. Health expectancy and the problem of substitute morbidity.

    1997-12-29

    During the past century, the developed world has not only witnessed a dramatic increase in life expectancy (ageing), but also a concomitant rise in chronic disease and disability. Consequently, the tension between 'living longer' on the one hand and health-related 'quality of life' on the other has become an increasingly important health policy problem. The paper deals with two consequences of this so-called epidemiological transition in population health. The first one concerns the question of how--given the impressive changes--population health can be measured in an adequate and policy relevant present-day fashion. The second one is the so-called phenomenon of 'substitute morbidity and mortality': more and more acute fatal diseases are replaced by non-fatal delayed degenerative diseases like dementia and arthritis. How the phenomenon of substitute morbidity and mortality affects the development of population health is illustrated with the epidemiological transitions, worldwide shifts in the main causes of death, assumptions used in models, adverse consequences of medical technologies and some results from intervention trials. Substitute morbidity and mortality may thwart our disease-specific expectations of interventions and asks for a shift to a 'total population health' perspective when judging potential health gains of interventions. Better understanding of the dynamics that underly the changes in population health is necessary. Implications for data collections are more emphasis on morbidity data and their relation with mortality, more longitudinal studies, stricter requirements for intervention trials and more use of modelling as a tool. A final recommendation is the promotion of integrative measures of population health. For the latter several results are presented suggesting that, although the amount of morbidity and disability is growing with an increasing life expectancy, this is mild unhealthiness in particular. This finding supports the 'dynamic

    Gao Yang; Xu Sipeng; Zhao Baosheng

    2008-01-01

    A theory of general solutions of three-dimensional (3D) problems is developed for the coupled equilibrium equations in 1D hexagonal quasicrystals (QCs), and two new general solutions, which are called generalized Lekhnitskii-Hu-Nowacki (LHN) and Elliott-Lodge (E-L) solutions, respectively, are presented based on three theorems. As a special case, the generalized LHN solution is obtained from our previous general solution by introducing three high-order displacement functions. For further simplification, considering three cases in which three characteristic roots are distinct or possibly equal to each other, the generalized E-L solution shall take different forms, and be expressed in terms of four quasi-harmonic functions which are very simple and useful. It is proved that the general solution presented by Peng and Fan is consistent with one case of the generalized E-L solution, while does not include the other two cases. It is important to note that generalized LHN and E-L solutions are complete in z-convex domains, while incomplete in the usual non-z-convex domains

    Professionals who provide nutrition education and consulting to the public are encouraged to take into account the health, environmental and social contexts that influence health-related attitudes and behaviours in the population. This paper examined the awareness of shifts in population health outcomes associated with the nutrition transition in Vietnam among university nutrition lecturers, health professionals and school education professionals. Most of these professionals held accurate views of the current population health issues in Vietnam. However, they differed in their awareness of the seriousness of overweight and obesity. Although the majority indicated that the prevalence of obesity and non-communicable diseases (NCDs) had increased, nearly half believed that the government should complete its attempts to control undernutrition before trying to control obesity. More health professionals believed that food marketing was responsible for the growing prevalence of children's obesity, and more of them disapproved of the marketing of less healthy food to children. In contrast, the university nutrition lecturers were least aware of food marketing and the seriousness of obesity. Of the three groups, the university nutrition lecturers held less accurate perceptions of nutrition transition problems and their likely drivers. There is an urgent need for greater provision of public nutrition education for all three groups of professionals. © The Author 2016. Published by Oxford University Press. All rights reserved.

    Full Text Available We consider a multiobjective linear fractional transportation problem (MLFTP with several fractional criteria, such as, the maximization of the transport profitability like profit/cost or profit/time, and its two properties are source and destination. Our aim is to introduce MLFTP which has not been studied in literature before and to provide a fuzzy approach which obtain a compromise Pareto-optimal solution for this problem. To do this, first, we present a theorem which shows that MLFTP is always solvable. And then, reducing MLFTP to the Zimmermann’s “min” operator model which is the max-min problem, we construct Generalized Dinkelbach’s Algorithm for solving the obtained problem. Furthermore, we provide an illustrative numerical example to explain this fuzzy approach.

To overcome the difficulties, due to the presence of a proper convex lower semi-continuous function, φ and a mapping g, which appeared in the considered problem, we have used some applications of the resolvent operator technique. We would like to point out that although many authors have proved results for finding solutions of the systems of nonlinear set-valued (mixed variational inequalities problems, it is clear that it cannot be directly applied to the problems that we have considered in this paper because of φ and g. 2000 AMS Subject Classification: 47H05; 47H09; 47J25; 65J15.

Low health literacy is as barrier for understanding medical recommendations, disease prevention and health care. To assess women's health literacy and relative factors in Mashhad (Iran). Women referring to healthcare centers in Mashhad in 2012 and 2013, participated in this cross-sectional study by stratified sampling method. The validated Persian version of Rapid Estimate of Adult Literacy in Medicine-revised questionnaire was used. Vocabulary comprehension and reading scores of health literacy was assessed. Comparisons were done in demographic subgroups by ANOVA, Mann-Whitney U, Kruskal-Wallis, Pearson correlation coefficient, and Chi-Square tests. In total, 250 women with a mean age of 32.1±10.23 years and the mean education level of 10.58±3.67 years were studied. The mean reading score was 11.58±2.51 and the mean vocabulary comprehension score was 17.24±4.73. Participants' health literacy score had positive correlation with age and education, and significant difference in health literacy scores between occupational groups was seen. Housewives' health literacy scores were lower than others (pliteracy was a common problem amongst younger women, especially among women who had less education. These women are at risk of early marriage and child bearing and require more health care. Health care professionals should use effective methods for easier transfer recommendation, also, producing medical information booklets, texts, and videos for different community subgroups through public media or even in cyberspace with clear and common words consisting of essential information.

    Health maintenance and improvement of humans, artifacts, and nature are pressing requirements considering the problems human beings have faced. In this article, the health management technology is proposed by centering cause-effect structure. The important aspect of the technology is evolvement through human-machine collaboration in response to changes of target systems. One of the reasons why the cause-effect structure is centered in the technology is its feature of transparency to humans by instinct point of view. The notion has been spreaded over wide application areas such as quality control, energy management, and healthcare. Some experiments were conducted to prove effectiveness of the technology in the article.

    Equity in health care across all social groups is a major goal in health care policy. Immigrants may experience more mental health problems than natives, but we do not know the extent to which they seek help from primary health care services. This study aimed to determine a) the rate immigrants use primary health care services for mental health problems compared with Norwegians and b) the association between length of stay, reason for immigration and service use among immigrants. National register data covering all residents in Norway and all consultations with primary health care services were used. We conducted logistic regression analyses to compare Norwegians' with Polish, Swedish, German, Pakistani and Iraqi immigrants' odds of having had a consultation for a mental health problem (P-consultation). After accounting for background variables, all immigrants groups, except Iraqi men had lower odds of a P-consultation than their Norwegian counterparts. A shorter length of stay was associated with lower odds of a P-consultation. Service use varies by country of origin and patterns are different for men and women. There was some evidence of a possible 'healthy migrant worker' effect among the European groups. Together with previous research, our findings however, suggest that Iraqi women and Pakistanis in particular, may experience barriers in accessing care for mental health problems.

METHODS: We analyzed data from the 2011 Korean Community Health Survey. From the total of 229,226 participants aged 19 years or above, we excluded 48,679 current smokers, 36,612 former smokers, 3,036 participants with a history of stroke, 2,264 participants with a history of myocardial infarction, 14,115 participants who experienced at least one day in bed per month due to disability, and 855 participants for whom information regarding SHSE or mental health problems was not available. The final analysis was performed with 22,818 men and 100,847 women. Participants were classified into four groups according to the duration of SHSE: none, <1 hr/d, 1-<3 hr/d, and ≥3 hr/d. The presence of depressive symptoms, diagnosed depression, and high stress were measured by questionnaire. RESULTS: After adjusting for demographic factors, lifestyle, and chronic disease, the odds ratio (OR and 95% confidence interval (CI of depressive symptoms with 1-<3 hr/d and ≥3 hr/d SHSE were 1.44 (95% CI, 1.14 to 1.82 and 1.59 (95% CI, 1.46 to 1.74, respectively. However, SHSE ≥3 hr/d had a higher OR of 1.37 (95% CI, 1.20 to 1.58 for diagnosed depression. SHSE was also associated with high stress (1-<3 hr/d: OR, 1.56; 95% CI, 1.38 to 1.76; ≥3 hr/d: OR, 1.33 95% CI, 1.28 to 1.40. However, the association between SHSE and symptoms of depression and stress did not differ significantly by region. CONCLUSIONS: SHSE may be associated with mental health problems such as depression and stress in Korean adults.

    Understanding the developmental course of all health issues associated with preterm birth is important from an individual, clinical and public health point-of-view. Both the number of preterm births and proportion of survivors have increased steadily in recent years. The UK Millennium Cohort Study (n = 18,818) was used to examine the association of gestational age with maternal ratings of general health and behavior problems at ages 5 and 11 years using binary and multinomial logistic regression analyses. The association between mothers' ratings of general health and behavior problems was relatively weak at each time point. Children rated as being in poor general health remained constant over time (4.0 % at age 5, 3.8 % at age 11), but children rated as having behavioral problems increased by almost 100 % (5.6 % at 5; 10.5 % at 11). A gradient of increasing risk with decreasing gestational age was observed for a composite health measure (general health problems and/or behavior problems) at age 5, amplified at age 11 and was strongest for those with chronic problems (poor health at both age 5 and age 11). This association was found to be compounded by child sex, maternal characteristics at birth (education, employment, marital status) and duration of breast feeding. Integrated support to at-risk families initiated during, or soon after pregnancy, may prevent chronic problems and might potentially reduce long term health costs for both the individual and health services.

Data were analyzed from the World Health Organization's World Health Survey (WHS), a population-based survey conducted in 70 countries between 2002 and 2004. 261,547 individuals aged ≥ 18 years from 56 countries. N/A. The presence of psychotic symptoms in the past 12 months was established using 4 questions pertaining to positive symptoms from the psychosis screening module of the Composite International Diagnostic Interview. Sleep problems referred to severe or extreme sleep problems in the past 30 days. Multivariable logistic regression was used to estimate the associations. The overall prevalence of sleep problems was 7.6% and ranged from 1.6% (China) to 18.6% (Morocco). Sleep problems were associated with significantly higher odds for at least one psychotic symptom in the vast majority of countries. In the pooled sample, after adjusting for demographic factors, alcohol consumption, smoking, and chronic medical conditions, having sleep problems resulted in an odds ratio (OR) for at least one psychotic symptom of 2.41 (95% confidence interval [CI] 2.18-2.65). This OR was 1.59 (1.40-1.81) when further adjusted for anxiety and depression. A strong association between sleep problems and psychotic symptoms was observed globally. These results have clinical implications and serve as a basis for future studies to elucidate the causal association between psychotic symptoms and sleep problems. © 2015 Associated Professional Sleep Societies, LLC.

  15. Generalized multiscale finite element methods for problems in perforated heterogeneous domains

    2015-06-08

    Complex processes in perforated domains occur in many real-world applications. These problems are typically characterized by physical processes in domains with multiple scales. Moreover, these problems are intrinsically multiscale and their discretizations can yield very large linear or nonlinear systems. In this paper, we investigate multiscale approaches that attempt to solve such problems on a coarse grid by constructing multiscale basis functions in each coarse grid, where the coarse grid can contain many perforations. In particular, we are interested in cases when there is no scale separation and the perforations can have different sizes. In this regard, we mention some earlier pioneering works, where the authors develop multiscale finite element methods. In our paper, we follow Generalized Multiscale Finite Element Method (GMsFEM) and develop a multiscale procedure where we identify multiscale basis functions in each coarse block using snapshot space and local spectral problems. We show that with a few basis functions in each coarse block, one can approximate the solution, where each coarse block can contain many small inclusions. We apply our general concept to (1) Laplace equation in perforated domains; (2) elasticity equation in perforated domains; and (3) Stokes equations in perforated domains. Numerical results are presented for these problems using two types of heterogeneous perforated domains. The analysis of the proposed methods will be presented elsewhere. © 2015 Taylor & Francis

    Building Our Solutions and Connections (BOSC) focused on enhancing problem-solving skills (PSS) of primary caregivers of children with mental health problems. Aims were determining feasibility, acceptability, and effect size (ES) estimates for depression, burden, personal control, and PSS. Caregivers were randomized to BOSC (n=30) or wait-list control (WLC) groups (n=31). Data were collected at baseline, post-intervention, and 3 and 6 months post-intervention. Three-months post-intervention, ES for burden and personal control were .07 and .08, respectively. ES for depressed caregivers for burden and personal control were 0.14 and 0.19, respectively. Evidence indicates that the intervention had desired effects. Published by Elsevier Inc.

    Primary care paediatricians' perception of migrant children's health in Europe has not been explored before. Our aim was to examine European paediatricians' knowledge on migrant children's health problems, needs, inequalities, and barriers to access health care. European primary care paediatricians were invited by the European Academy of Paediatrics Research in Ambulatory Setting Network country coordinators to complete a web-based survey concerning health care of migrant children. A descriptive analysis of all variables was performed. The survey was completed by 492 paediatricians. Sixty-three per cent of the respondents reported that the general health of migrant children is worse than that of nonmigrants, chronic diseases cited by 66% of the respondents as the most frequent health problem. Sixty-six per cent of the paediatricians reported that migrant children have different health needs compared to nonmigrant children, proper oral health care mentioned by 86% of the respondents. Cultural/linguistic factors have been reported as the most frequent barrier (90%).to access health care. However, only 37% of providers have access to professional interpreters and cultural mediators. Fifty-two per cent and 32% do not know whether one or more of the family members are undocumented and whether they are refugees/asylum seekers, respectively. Updated guidelines for care of migrant children are available for only 35% of respondents, and 80% of them have not received specific training on migrant children's care. European primary care paediatricians recognize migrant children as a population at risk with more frequent and specific health problems and needs, but they are often unaware of their legal state. Lack of interpreters augments the existing language barriers to access proper care and should be solved. Widespread lack of guidelines and specific providers' training should be addressed to optimize health care delivery to migrant children. © 2017 John Wiley & Sons Ltd.

  18. Variational methods for problems from plasticity theory and for generalized Newtonian fluids

    CERN Document Server

    Fuchs, Martin

    2000-01-01

    Variational methods are applied to prove the existence of weak solutions for boundary value problems from the deformation theory of plasticity as well as for the slow, steady state flow of generalized Newtonian fluids including the Bingham and Prandtl-Eyring model. For perfect plasticity the role of the stress tensor is emphasized by studying the dual variational problem in appropriate function spaces. The main results describe the analytic properties of weak solutions, e.g. differentiability of velocity fields and continuity of stresses. The monograph addresses researchers and graduate students interested in applications of variational and PDE methods in the mechanics of solids and fluids.

    Siblings of children with mental health problems (MHPs) have been found to have higher rates of psychopathology and impaired psychosocial functioning compared to control children. It is not yet known how these siblings are managed within the clinical service context (e.g., are they assessed for mental health problems? Do they receive appropriate psychological treatment?). The following brief report describes a pilot study which aimed to explore (a) the rate of caregiver-identified MHPs in siblings and (b) the proportion of siblings receiving psychiatric or psychosocial treatment or support (i.e., treatment utilisation). Eighty-five caregivers of children receiving treatment at CAMHS were interviewed about the mental health and treatment utilisation of their siblings. The findings revealed a high rate of caregiver-identified MHPs in siblings (34.1%) and a high rate of treatment utilisation (85.7%). The findings suggest that, for the vast majority, when siblings of children with MHPs are identified by their caregivers as having MHPs, they are receiving some kind of support and treatment. Implications for mental health service costs are discussed and recommendations for future research are outlined.

    Few individuals have access to mental health services due in part to underdetection. As it is more likely to consult for medical conditions, primary care may be a useful gateway for early detection of mental health problems. Detection of the frequency of mental health problems in four hospital services at the Fundación Santa Fe de Bogotá: Outpatient unit, hospitalization, emergency department, and primary care through a brief detection questionnaire, the Patient Health Questionnaire (PHQ). Cross-sectional study of patients seen at the four services who answered a Demographic Data Questionnaire and the PHQ together with information gathered about current medical diagnosis, history of visits, and hospitalizations during the last year. 1094 patients seen at the four hospital services between September 2010 and May 2011 were selected at random. A mental health problem was detected in 36.7% of the total sample. Major depressive disorder (7.3%), alcohol abuse (14.4%), and any anxiety disorder (7.7%) showed the highest prevalence with the emergency department showing the highest frequency of detection. The usefulness of a brief detection questionnaire such as the PHQ in hospital settings is demonstrated and implications in the design of mental health programs in the general hospital are discussed. The need to replicate this study in other settings and to undertake further research is outlined. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

  1. Vision problems are a leading source of modifiable health expenditures.

    Science.gov (United States)

    Rein, David B

    2013-12-13

    According to recent studies, visual problems represent one of the top contributors to economic health burden in the United States. This burden is divided nearly equally between direct expenditures for the care and treatment of visual problems, and the indirect costs of outcomes caused by low vision, including productivity losses, the cost of care, and incremental nursing home placements. A large amount of academic research is devoted to visual science, the biology of the visual system, and the medical treatment of visual disorders. Compared to the burden, a disproportionate share of this research is devoted to the study of retinal disorders and glaucoma. This is understandable, as research into the retina and optic nerve has the potential to unlock fundamental insights into the nature of sight and visual cognition. However, population visual health and the functionality that depends upon it also may benefit greatly from additional research into areas of prevention, rehabilitation, and adaptation. In addition, comparative research into the benefits of resource allocation across prevention, treatment, and rehabilitative resources could lead to improvements in population health.

    Violence within the family is a significant health problem which threatens the health of the community. The global rates of domestic violence directed at women have been reported as 10%-69% and in Turkey as 25%-30%. The data of our study were obtained from the database of the official internet website of the Turkish Statistics Institute as the data related to violence between 2007 and 2012. In the evaluation of the data, SPSS 11.0 statistics software was used. Although it was determined that women from all groups experienced sexual, physical and emotional violence, higher rates were observed in those living in rural areas compared to those in urban areas, in the eastern region compared to all other regions, in the 45-59 years age group, those with low level of income and with a low level of education. When physicians encounter women who have experienced violence, by evaluating the violence in the context of a legal case, violence is identified and not allowed to become a cycle passed from generation to generation, and in addition to the medical intervention, without forgetting that violence is a public health problem, it is necessary to find a way to provide psychosocial and legal support for the victim.

    Full Text Available An integrated model of health system responses to public health problems is considered to be the most preferable approach. Accordingly, there are several models that stipulate what an integrated architecture should look like. However, tools that can guide the overall process of integration are lacking. This tool is designed to guide the entire process of integration of health system responses to major public health problems. It is developed by taking into account the contexts of health systems of developing countries and the emergence of double-burden of chronic diseases in these settings. Chronic diseases – HIV/AIDS and NCDs – represented the evidence base for the development of the model. System level horizontal integration of health system responses were considered in the development of this tool.

    The paper deals with health problems of working-age population in the Russian Federation. According to foreign and domestic experts reduction of the able-bodied population and its fraction in the general population will be accompanied by ageing of labour force in the nearest two decades. Despite the growth of life expectancy in 2006-2007 demonstrated by disability, mortality and life expectancy indices for the age group of interest, its health status is considered to be critical. Mathematical simulation of mortality rates allowed for the assessment of potential years of life lost (PYLL) from leading causes of death among active working population. The data obtained provide a basis for the elaboration of medical and social programs aimed at increasing life expectancy. The most essential role in current negative tendencies in the health of active working population belongs to the deterioration of work conditions and safety at industrial enterprises coupled to low efficiency of occupational health prevention system accounting for the significantly reduced accessibility of health services. Restoration of occupational health system in Russia is of crucial importance. Experts of the Institute of Occupational Health have elaborated a draft National Action Plan designed to improve health protection of labour force in this country; its implementation would help to solve demographic problems and increase the amount and quality of labour force.

  6. Getting stuck in the blues: persistence of mental health problems in Australia.

    Do episodes of mental health (MH) problems cause future MH problems, and if yes, how strong are these dynamics? We quantify the degree of persistence in MH problems using nationally representative, longitudinal data from Australia and system generalized method of moments (GMM), and correlated random effects approaches are applied to separate true from spurious state dependence. Our results suggest only a moderate degree of persistence in MH problems when assuming that persistence is constant across the MH distribution once individual-specific heterogeneity is accounted for. However, individuals who fell once below a threshold that indicates an episode of depression are up to five times more likely to experience such a low score again a year later, indicating a strong element of state dependence in depression. Low income is a strong risk factor in state dependence for both men and women, which has important policy implications. Copyright © 2013 John Wiley & Sons, Ltd.

  8. Generalization of the geometric optical series approach for nonadiabatic scattering problems

    Herman, M.F.

    1982-01-01

    The geometric optical series approach of Bremmer is generalized for multisurface nonadiabatic scattering problems. This method yields the formal solution of the Schroedinger equation as an infinite series of multiple integrals. The zeroth order term corresponds to WKB propagation on a single adiabatic surface, while the general Nth order term involves N reflections and/or transitions between surfaces accompanied by ''free,'' single surface semiclassical propagation between the points of reflection and transition. Each term is integrated over all possible transition and reflection points. The adiabatic and diabatic limits of this expression are discussed. Numerical results, in which all reflections are ignored, are presented for curve crossing and noncrossing problems. These results are compared to exact quantum results and are shown to be highly accurate

    Despite being an ancient disease, leprosy remains a public health problem in several countries -particularly in India, Brazil and Indonesia. The current operational guidelines emphasize the evaluation of disability from the time of diagnosis and stipulate as fundamental principles for disease control: early detection and proper treatment. Continued efforts are needed to establish and improve quality leprosy services. A qualified primary care network that is integrated into specialized service and the development of educational activities are part of the arsenal in the fight against the disease, considered neglected and stigmatizing.

  13. Implementing primary health care: some problems of creating national programmes.

    Vaughan, J P; Walt, G

    1984-07-01

    While there is a great deal of agreement about the principles underlying Primary Health Care (PHC), there exist many problems, political, planning and management, involved in putting the approach into effect. Some of these difficulties are discussed. It is clear that the PHC approach is essentially political; the way it is implemented in each country will reflect the political priorities and systems of that country. Moreover, ministries of health are not known for their strong position in the ministerial pecking order. Finance and planning ministeries would have to be won over to the importance of the concept of PHC to try to eexpand the health budget and to change the emphasis of existing resource allocation patterns. Costs incurred by a PHC approach ( e.g., expensive transport and communication systems), and resources needed to finance it may be available; however, they may not be channelled to the politically less articulate groups in rural areas. Political implications are not limited to national levels; considerable conflict may exist between different status groups and classes at the village level, thus sabotaging PHC plans. Professional politics will also be played at all levels. It is equally essential to recognize the historical context in which PHC is being introduced. Many countries have inherited colonial infrastructures. Changing the values, perceptions, expectations, administration and organization that accompany such systems is extremely hard, and to put PHC into effect demands radical changes. The planning difficulties which beset PHC are related to the still large private provision of social services like health, and to a flourishing traditional private sector in many developing countries. These may limit the implementation of a national health policy and PHC may thus result in a very patchy service throughout the country. The level of centralized planning will also affect resource allocation and therefore the policy, planning and implementation

    Oelfke, U.; Bortfeld, T.

    1999-01-01

    Rotation therapy with photons is currently under investigation for the delivery of intensity modulated radiotherapy (IMRT). An analytical approach for inverse treatment planning of this radiotherapy technique is described. The inverse problem for the delivery of arbitrary 2D dose profiles is first formulated and then solved analytically. In contrast to previously applied strategies for solving the inverse problem, it is shown that the most general solution for the fluence profiles consists of two independent solutions of different parity. A first analytical expression for both fluence profiles is derived. The mathematical derivation includes two different strategies, an elementary expansion of fluence and dose into polynomials and a more practical approach in terms of Fourier transforms. The obtained results are discussed in the context of previous work on this problem. (author)

    The recent paper by Will (1983) is considered which purports to demonstrate that the gravitational radiation which the authors had computed from their model two-body free-fall system is consistent with the so-called quadrupole formula. It is shown that in fact the system presented by Will is different from the authors and that the illegitimate application of the quadrupole formula to the authors system leads to a smaller flux than that which is correctly deduced using general relativity and a proper consideration of nonlinearities. It is demonstrated that a judicious choice of stress release is propagated through the bodies as a superposition of plane and spherical waves leading to pressure fluctuations to the order in question. This underlines the essential distinction between the authors problem and the Will problem. Various aspects of the problem are also discussed. 25 references

    2000-01-01

    A study is made of the generalized Steiner problem: the problem of finding all the locally minimal networks spanning a given boundary set (terminal set). It is proposed to solve this problem by using an analogue of Morse theory developed here for planar linear networks. The space K of all planar linear networks spanning a given boundary set is constructed. The concept of a critical point and its index is defined for the length function l of a planar linear network. It is shown that locally minimal networks are local minima of l on K and are critical points of index 1. The theorem is proved that the sum of the indices of all the critical points is equal to χ(K)=1. This theorem is used to find estimates for the number of locally minimal networks spanning a given boundary set

    1994-12-31

    The solution of the large, sparse, symmetric eigenvalue problem, Ax = {lambda}x, is central to many scientific applications. Among many iterative methods that attempt to solve this problem, the Lanczos and the Generalized Davidson (GD) are the most widely used methods. The Lanczos method builds an orthogonal basis for the Krylov subspace, from which the required eigenvectors are approximated through a Rayleigh-Ritz procedure. Each Lanczos iteration is economical to compute but the number of iterations may grow significantly for difficult problems. The GD method can be considered a preconditioned version of Lanczos. In each step the Rayleigh-Ritz procedure is solved and explicit orthogonalization of the preconditioned residual ((M {minus} {lambda}I){sup {minus}1}(A {minus} {lambda}I)x) is performed. Therefore, the GD method attempts to improve convergence and robustness at the expense of a more complicated step.

  1. Australian health system restructuring - what problem is being solved?

    Science.gov (United States)

    Dwyer, Judith M

    2004-11-19

    BACKGROUND: In recent years, Australian state and territory governments have reviewed and restructured the health systems they lead and regulate. This paper examines the outcomes of the most recent official published reviews of systems and structures; identifies the common themes; and addresses two questions: what problems are being addressed? And how would we know if the changes were successful? RESULTS: In all the broad, systemic reviews, the main health system problems identified were money, hospital utilisation and a weak primary health care system. The solutions are various, but there is a common trend towards centralisation of governance, often at state health authority level, and stronger accountability measures. Other common themes are hospital substitution (services to avoid the need for admission); calls for cooperation across the Commonwealth:state divide, or for its abolition; and the expected range of current efficiency and effectiveness measures (eg amalgamate pathology and support services) and ideas in good currency (eg call centres). The top-down nature of the public review process is noted, along with the political nature of the immediate catalysts for calling on a review. CONCLUSION: The long-standing tension between the pull to centralisation of authority and the need for innovation in care models is heightened by recent changes, which may be counterproductive in an era dominated by the burden of chronic disease. I argue that the current reforms will not succeed in achieving the stated goals unless they make a difference for people with chronic illness. And if this is correct, the most useful focus for evaluation of the success of the reforms may be their impact on the system's ability to develop and deliver better models of care for this growing group of patients.

  2. A complete basis for a perturbation expansion of the general N-body problem

    International Nuclear Information System (INIS)

    Laing, W Blake; Kelle, David W; Dunn, Martin; Watson, Deborah K

    2009-01-01

    We discuss a basis set developed to calculate perturbation coefficients in an expansion of the general N-body problem. This basis has two advantages. First, the basis is complete order-by-order for the perturbation series. Second, the number of independent basis tensors spanning the space for a given order does not scale with N, the number of particles, despite the generality of the problem. At first order, the number of basis tensors is 25 for all N, i.e. the problem scales as N 0 , although one would initially expect an N 6 scaling at first order. The perturbation series is expanded in inverse powers of the spatial dimension. This results in a maximally symmetric configuration at lowest order which has a point group isomorphic with the symmetric group, S N . The resulting perturbation series is order-by-order invariant under the N! operations of the S N point group which is responsible for the slower than exponential growth of the basis. In this paper, we demonstrate the completeness of the basis and perform the first test of this formalism through first order by comparing to an exactly solvable fully interacting problem of N particles with a two-body harmonic interaction potential

  3. Solving the generalized symmetric eigenvalue problem using tile algorithms on multicore architectures

    KAUST Repository

    Ltaief, Hatem

    2012-01-01

    This paper proposes an efficient implementation of the generalized symmetric eigenvalue problem on multicore architecture. Based on a four-stage approach and tile algorithms, the original problem is first transformed into a standard symmetric eigenvalue problem by computing the Cholesky factorization of the right hand side symmetric definite positive matrix (first stage), and applying the inverse of the freshly computed triangular Cholesky factors to the original dense symmetric matrix of the problem (second stage). Calculating the eigenpairs of the resulting problem is then equivalent to the eigenpairs of the original problem. The computation proceeds by reducing the updated dense symmetric matrix to symmetric band form (third stage). The band structure is further reduced by applying a bulge chasing procedure, which annihilates the extra off-diagonal entries using orthogonal transformations (fourth stage). More details on the third and fourth stage can be found in Haidar et al. [Accepted at SC\\'11, November 2011]. The eigenvalues are then calculated from the tridiagonal form using the standard LAPACK QR algorithm (i.e., DTSEQR routine), while the complex and challenging eigenvector computations will be addressed in a companion paper. The tasks from the various stages can concurrently run in an out-of-order fashion. The data dependencies are cautiously tracked by the dynamic runtime system environment QUARK, which ensures the dependencies are not violated for numerical correctness purposes. The obtained tile four-stage generalized symmetric eigenvalue solver significantly outperforms the state-of-the-art numerical libraries (up to 21-fold speed up against multithreaded LAPACK with optimized multithreaded MKL BLAS and up to 4-fold speed up against the corresponding routine from the commercial numerical software Intel MKL) on four sockets twelve cores AMD system with a 24000×24000 matrix size. © 2012 The authors and IOS Press.

    Zachrisson, Henrik D; Rödje, Kjetil; Mykletun, Arnstein

    2006-01-01

    Background Only a minority of adolescents reporting symptoms above case-levels on screenings for mental health seeks and receives help from specialist health services. The objective of this study was to a) examine help-seeking for symptoms of anxiety and depression in relation to symptom load dimensionally, b) identify the level of specialization in mental health among service-providers, and c) identify associations between mental health problems and contact with different types of health services. Methods This cross-sectional school-based study (response-rate 88%, n = 11154) is based on Norwegian health surveys among 15 and 16 year olds. Results We found a dose-response association between symptom-load and help seeking. Only 34% of individuals with mental symptom-load above 99th percentile reported help-seeking in the last 12 months. Forty percent of help seekers were in contact with specialists (psychiatrists or psychologists), the remaining were mainly in contact with GPs. Mental health problems increased help seeking to all twelve service providers examined. Conclusion It might not be reasonable to argue that all adolescents with case-level mental health problems are in need of treatment. However, concerning the 99th percentile, claiming treatment need is less controversial. Even in the Norwegian context where mental health services are relatively available and free of charge, help-seeking in individuals with the highest symptom-loads is still low. Most help seekers achieved contact with health care providers, half of them at a non specialized level. Our results suggest that adolescents' recognition of mental health problems or intention to seek help for these are the major "filters" restricting treatment. PMID:16480522

    General practice is the corner stone of Danish primary health care. General practitioners (GPs) are similar to family physicians in the United States. On average, all Danes have 6.9 contacts per year with their GP (in-person, telephone, or E-mail consultation). General practice is characterized...... education. The contract is (re)negotiated every 2 years. General practice is embedded in a universal tax-funded health care system in which GP and hospital services are free at the point of use. The current system has evolved over the past century and has shown an ability to adapt flexibly to new challenges...... by 5 key components: (1) a list system, with an average of close to 1600 persons on the list of a typical GP; (2) the GP as gatekeeper and first-line provider in the sense that a referral from a GP is required for most office-based specialists and always for in- and outpatient hospital treatment; (3...

  8. Worker Attitudes towards Mental Health Problems and Disclosure

    CS Dewa

    2014-09-01

    Full Text Available Background: There is a significant proportion of workers with mental disorders who either are struggling at work or who are trying to return to work from a disability leave. Objective: Using a population-based survey of working adults in Ontario, Canada, this paper examines the perceptions of workers towards mental disorders in the workplace. Methods: Data are from a sample of 2219 working adults identified through random digit dialing who either completed a telephone questionnaire administered by professional interviewers or a web-based survey. Results: A third of workers would not tell their managers if they experienced mental health problems. Rather than a single factor, workers more often identified a combination of factors that would encourage disclosure to their managers. One of the most identified disincentives was the fear of damaging their careers. The most pervasive reasons for concerns about a colleague with a mental health problem included safety and the colleague's reliability. Conclusion: Although critical for workers who experience a mental disorder and who find work challenging, a significant proportion do not seek support. One barrier is fear of negative repercussions. Organizations' policies can create safe environments and the provision of resources and training to managers that enable them to implement them. By making disclosure safe, stigma and the burden of mental disorders in the workplace can be decreased.

    The use of addictive substances-tobacco, alcohol, and other drugs-during adolescence interferes with brain development and increases the risk of serious health and mental health conditions, including addiction. Yet, adolescents live in a culture in which family, social, community, and media influences regularly bombard them with pro-substance use messages, creating an environment in which substance use is considered an expected behavior, rather than a considerable health risk. To prevent the significant harm that falls to teens and young adults because of substance use, The National Center on Addiction and Substance Abuse at Columbia University (CASA Columbia) undertook a study to explore how adolescent brain development relates to the risk of substance use and addiction; the cultural influences that create an environment in which substance use is considered normative behavior; individual factors that make some teens more disposed to substance use and addiction; and evidence-based prevention and treatment strategies for addressing this problem. The recently published report Adolescent Substance Use: America's #1 Public Health Problem concludes that risky substance use is a major public health problem that can be ameliorated through evidence-based public health measures, including education about the disease and its risk factors, screenings, and clinical interventions, and that addiction can be treated and managed effectively within routine health care practice and specialty care.

    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

    Full Text Available Abstract Background In order to get sickness benefit a sick-listed person need a medical certificate issued by a physician; in Sweden after one week of self-certification. Physicians experience sick-listing tasks as problematic and conflicts may arise when patients regard themselves unable to work due to complaints that are hard to objectively verify for the physician. Most GPs and orthopaedic surgeons (OS deal regularly with sick-listing issues in their daily practice. The aim of this study was to explore perceived problems and coping strategies related to tasks of sickness certification among general practitioners (GP and orthopaedic surgeons (OS. Methods A cross-sectional study about sickness certification in two Swedish counties, with 673 participating GPs and 149 OSs, who answered a comprehensive questionnaire. Frequencies together with crude and adjusted (gender and working years Odds ratios were calculated. Results A majority of the GPs and OSs experienced problems in sickness certification every week. To assess the patient's work ability, to handle situations when they and the patient had different opinions about the need for sickness absence, and to issue prolongation certificates when the previous was issued by another physician were reported as problematic by a majority in both groups. Both GPs and OSs prolonged sickness certifications due to waiting times in health care or at Social Insurance Office (SIO. To handle experienced problems they used different strategies; OSs issued sickness certificates without personal appointment more often than the GPs, who on the other hand reported having contact with SIO more often than the OSs. A higher rate of GPs experienced support from management and had a common strategy for handling sickness certification at the clinic than the OSs. Conclusion Most GPs and OSs handled sickness certification weekly and reported a variety of problems in relation to this task, generally GPs to a higher extent

  12. Approximation in generalized Hardy classes and resolution of inverse problems for tokamaks

    International Nuclear Information System (INIS)

    Fisher, Y.

    2011-11-01

    This thesis concerns both the theoretical and constructive resolution of inverse problems for isotropic diffusion equation in planar domains, simply and doubly connected. From partial Cauchy boundary data (potential, flux), we look for those quantities on the remaining part of the boundary, where no information is available, as well as inside the domain. The proposed approach proceeds by considering solutions to the diffusion equation as real parts of complex valued solutions to some conjugated Beltrami equation. These particular generalized analytic functions allow to introduce Hardy classes, where the inverse problem is stated as a best constrained approximation issue (bounded extrema problem), and thereby is regularized. Hence, existence and smoothness properties, together with density results of traces on the boundary, ensure well-posedness. An application is studied, to a free boundary problem for a magnetically confined plasma in the tokamak Tore Supra (CEA Cadarache France). The resolution of the approximation problem on a suitable basis of functions (toroidal harmonics) leads to a qualification criterion for the estimated plasma boundary. A descent algorithm makes it decrease, and refines the estimations. The method does not require any integration of the solution in the overall domain. It furnishes very accurate numerical results, and could be extended to other devices, like JET or ITER. (author)

  13. Stigma as a barrier to seeking health care among military personnel with mental health problems.

    Approximately 60% of military personnel who experience mental health problems do not seek help, yet many of them could benefit from professional treatment. Across military studies, one of the most frequently reported barriers to help-seeking for mental health problems is concerns about stigma. It is, however, less clear how stigma influences mental health service utilization. This review will synthesize existing research on stigma, focusing on those in the military with mental health problems. We conducted a systematic review and meta-analysis of studies between 2001 and 2014 to examine the prevalence of stigma for seeking help for a mental health problem and its association with help-seeking intentions/mental health service utilization. Twenty papers met the search criteria. Weighted prevalence estimates for the 2 most endorsed stigma concerns were 44.2% (95% confidence interval: 37.1, 51.4) for "My unit leadership might treat me differently" and 42.9% (95% confidence interval: 36.8, 49.0) for "I would be seen as weak." Nine studies found no association between anticipated stigma and help-seeking intentions/mental health service use and 4 studies found a positive association. One study found a negative association between self-stigma and intentions to seek help. Counterintuitively, those that endorsed high anticipated stigma still utilized mental health services or were interested in seeking help. We propose that these findings may be related to intention-behavior gaps or methodological issues in the measurement of stigma. Positive associations may be influenced by modified labeling theory. Additionally, other factors such as self-stigma and negative attitudes toward mental health care may be worth further attention in future investigation. © The Author 2015.

    Seasonal migration of people in search of Yarsagumba fungus creates a population of collectors that faces hardship and health risks in austere high-altitude settings. In 2016, our 4-person team performed a 2-day health-needs survey of people collecting Yarsagumba fungus near the village of Yak Kharka (4020 m) in the Manang District of Nepal. There were approximately 800 people, both male and female, from age 10 to over 60, collecting Yarsagumba fungus. They had paid high prices for permits, hoping to recoup the cost and make a profit by selling specimens of Yarsagumba, but the fungus seemed scarce in 2016, resulting in a bleak economic forecast. Most collectors were living in austere conditions, walking long hours to the collection areas early in the morning and returning in the late afternoon. Most were subsisting on 1 daily meal. Health problems, including acute mountain sickness as well as respiratory and gastrointestinal illnesses, were common. Yarsagumba has become harder to find in recent years, increasing hardships and risk of injury. Medical care was almost nonexistent. As abundance decreases and demand increases, there is increasing pressure on collectors to find Yarsagumba. The collectors are an economically disadvantaged population who live in austere conditions at high altitude with poor shelter and sanitation, strenuous work, and limited availability of food. Health care resources are very limited. There are significant risks of illness, injury, and death. Targeted efforts by government entities and nongovernmental organizations might be beneficial in meeting the health needs. Copyright © 2017 Wilderness Medical Society. Published by Elsevier Inc.

    2006-11-01

    This paper describes general practitioners' (GPs) experiences of detecting and managing alcohol and alcohol-related problems in consultations. We undertook qualitative research in two phases in the North-East of England. Initially, qualitative interviews with 29 GPs explored their everyday work with patients with alcohol-related issues. We then undertook group interviews--two with GPs and one with a primary care team--where they discussed and challenged findings of the interviews. The GPs reported routinely discussing alcohol with patients with a range of alcohol-related problems. GPs believed that this work is important, but felt that until patients were willing to accept that their alcohol consumption was problematic they could achieve very little. They tentatively introduced alcohol as a potential problem, re-introduced the topic periodically, and then waited until the patient decided to change their behaviour. They were aware that they could identify and manage more patients. A lack of time and having to work with the multiple problems that patients brought to consultations were the main factors that stopped GPs managing more risky drinkers. Centrally, we compared the results of our study with [Thom, B., & Tellez, C. (1986). A difficult business-Detecting and managing alcohol-problems in general-practice. British Journal of Addiction, 81, 405-418] seminal study that was undertaken 20 years ago. We show how the intellectual, moral, emotional and practical difficulties that GPs currently face are quite similar to those faced by GPs from 20 years ago. As the definition of what could constitute abnormal alcohol consumption has expanded, so the range of consultations that they may have to negotiate these difficulties in has also expanded.

    Perceptions about general environmental problems, governmental spending for these problems, and major concerns about the US Department of Energy's Los Alamos National Laboratory (LANL) were examined by interviewing 356 people attending a gun show in Albuquerque, New Mexico. The hypothesis that there are differences in these three areas as a function of ethnicity was examined. We predicted that if differences existed, they would exist for all three evaluations (general environmental problems, government spending, and environmental concerns about LANL). However, this was not the case; there were fewer ethnic differences concerning LANL. Hispanics rated most general environmental problems higher than Whites and rated their willingness to expend federal funds higher than Whites, although all groups gave a lower score on willingness than on concern. Further, the congruence between these two types of ratings was higher for Hispanics than for others. In general, the concerns expressed by subjects about LANL showed few ethnic differences, and everyone was most concerned about contamination. These data indicate that Hispanics attending a gun show are equally or more concerned than others about environmental problems generally but are not more concerned about LANL. The data can be useful for developing future research and stewardship plans and for understanding general environmental problems and their relationship to concerns about LANL. More generally, they indicate that the attitudes and perceptions of Hispanics deserve increased study in a general population

    Collaboration between general practice and mental health care has been recognised as necessary to provide good quality healthcare services to people with mental health problems. Several studies indicate that collaboration often is poor, with the result that patient' needs for coordinated services are not sufficiently met, and that resources are inefficiently used. An increasing number of mental health care workers should improve mental health services, but may complicate collaboration and coordination between mental health workers and other professionals in the treatment chain. The aim of this qualitative study is to investigate strengths and weaknesses in today's collaboration, and to suggest improvements in the interaction between General Practitioners (GPs) and specialised mental health service. This paper presents a qualitative focus group study with data drawn from six groups and eight group sessions with 28 health professionals (10 GPs, 12 nurses, and 6 physicians doing post-doctoral training in psychiatry), all working in the same region and assumed to make professional contact with each other. GPs and mental health professionals shared each others expressions of strengths, weaknesses and suggestions for improvement in today's collaboration. Strengths in today's collaboration were related to common consultations between GPs and mental health professionals, and when GPs were able to receive advice about diagnostic treatment dilemmas. Weaknesses were related to the GPs' possibility to meet mental health professionals, and lack of mutual knowledge in mental health services. The results describe experiences and importance of interpersonal knowledge, mutual accessibility and familiarity with existing systems and resources. There is an agreement between GPs and mental health professionals that services will improve with shared knowledge about patients through systematic collaborative services, direct cell-phone lines to mental health professionals and allocated

    Teenage fecundity rates are an indicator of epidemiological discrimination in developing countries. To study fertility rates of girls under 14 years of age in Chile from 1993 to 2003. Information of children born alive from mothers aged 10 to 15 years, was obtained from the Chilean National Institute of Statistics. Age segmented population data was obtained from the Ministry of Health. Trends were analyzed by regions and single ages. The rates in communities of the Metropolitan Region were compared. Between 1993 and 2003, there was an increasing trend in fecundity rates, ratios and crude numbers. These rates duplicate from 14 to 15 years of age. In the Metropolitan Region, the fecundity ratios of communities with lower economical incomes is seven times greater than those with higher incomes. During 2003, the fecundity rates in Chile were 100 and 10 higher than those of Holland and Sweden in 1981. In developing countries with very low infant mortality rates such as Chile, the high fecundity rates of young girls is an indicator of a deficient human and social development. Sexual Education and Health Services for adolescents are essential to prevent this public health problem.

    Situated in the central region of South Africa, the Vaal Triangle is an area which plays a vital role in driving the economic dynamo of South Africa. Also, because of the concentration of heavy industry, it is an area which provides a challenge in effective air pollution control. The Vaal Triangle lies within the Vaal River Basin, at an altitude of 1 500 m above sea level. Meteorological conditions in the area are highly conducive to the formation of surface temperature inversions, resulting in a poor dispersion potential. Because of multiple sources of air pollution in the area, poor dispersion conditions increase the risk pollution build-up and subsequent adverse impacts. The situation is further exacerbated by the continued combustion of coal in households, even after the electrification of residences. This is particularly chronic in the developing communities and during winter. Vaal Triangle Air Pollution Health Study (VAPS) was initiated in 1990 by the Department of Health, the Medical Research Council and major industries in the area to determine effects of air pollution on the health of the community. The final results of that study summarised in this article, and options to ameliorate problems are addressed. (author)

  3. Singular perturbations of manifolds, with applications to the problem of motion in general relativity

    International Nuclear Information System (INIS)

    Kates, R.E.

    1979-01-01

    This thesis shows that a small body with possibly strong internal gravity moves through an empty region of a curved, and not necessarily asymptotically flat, external spacetime on an approximate geodesic. By approximate geodesic, the following is meant: Suppose the ratio epsilon = m/L 1 - where m is the body's mass and L is a curvature reference length of the external field - is a small parameter. Then the body's worldline deviates from a geodesic only by distances of at most THETA(epsilon) L over times of order L. The worldline is calculated directly from the Einstein field equation using a singular perturbation technique that has been generalized from the method of matched asymptotic expansions. The need for singular perturbation techniques has long been appreciated in fluid mechanics, where they are now standard procedure in problems in which the straightforward expansion in powers of a small parameter fails to give a correct qualitative picture. In part I of this thesis, singular perturbations on manifolds are formulated in a coordinate-free way suitable for treating problems in general relativity and other field theories. Most importantly for this thesis, the coordinate-free formulation of singular perturbations given in part I is essential for treatment of the problem of motion in part II

    Full Text Available Aiming at the problem of ant colony algorithm for solving Job一shop scheduling problem. Considering the complexity of the algorithm that uses disjunctive graph to describe the relationship between workpiece processing. To solve the problem of optimal solution,a generalized ant colony algorithm is proposed. Under the premise of considering constrained relationship between equipment and process,the pheromone update mechanism is applied to solve Job-shop scheduling problem,so as to improve the quality of the solution. In order to improve the search efficiency,according to the state transition rules of ant colony algorithm,this paper makes a detailed study on the selection and improvement of the parameters in the algorithm,and designs the pheromone update strategy. Experimental results show that a generalized ant colony algorithm is more feasible and more effective. Compared with other algorithms in the literature,the results prove that the algorithm improves in computing the optimal solution and convergence speed.

    Past research has shown that among the general public, certain causal explanations like biomedical causes are associated with stronger desire for social distance from persons with mental illness. Aim of this study was to find out how different causal attributions of persons with untreated mental health problems regarding their own complaints are associated with stigmatizing attitudes, anticipated self-stigma when seeking help and perceived stigma-stress. Altogether, 207 untreated persons with a current depressive syndrome were interviewed. Biomedical causes, but also belief in childhood trauma or unhealthy behavior as a cause of the problem, were associated with stronger personal stigma and with more stigma-stress. Similarities and differences to findings among the general population and implications for future research are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available A state of well being in which one realizes own potentials, can cope with every day stressors, can work productively and is able to constructively contribute to community is called mental health. Many stressful and negative events can interfere with these abilities and thus endanger someone’s mental health. Migration is one of them. With its’ pre and post phases/stages, migration represents great sources of stress and stressors. Immigrants need good personal and social resource in order to lessen down negative effects of migration on their mental health. The aim of this study is to explore presence of mental health problems in non clinical population of Bosnian immigrants (N=101, F=48, M=53 in Switzerland. It was assumed that migration stress acts negatively on immigrant’s mental health. General health questionnaire was used to test this hypothesis. Participants mean score results on total GHQ28 questionnaire were M=51.06, S.D. =14.30, its subscales on depression M=10.12 S.D.=3.75, somatic complaints M=13.04 S.D.=4.5, anxiety/insomnia M=13.34 S.D. 4.8, and social dysfunction M=14.37 S.D.=3.5. This indicates presence of mental health problems among Bosnian immigrants. At the same time, the study shows presence of social support seeking (N=83 subjects listed family and friends as primary coping strategy used by Bosnian immigrants while dealing with difficulties and problems rather than seeking professional help (N=3 subjects listed professional help seeking. Thus, social support seeking acts positively on mental health of Bosnian immigrants.

    There is currently much focus on provision of general physical health advice to people with serious mental illness and there has been increasing pressure for services to take responsibility for providing this. To review the effects of general physical healthcare advice for people with serious mental illness. We searched the Cochrane Schizophrenia Group's Trials Register (last update search October 2012) which is based on regular searches of CINAHL, BIOSIS, AMED, EMBASE, PubMed, MEDLINE, PsycINFO and registries of Clinical Trials. There is no language, date, document type, or publication status limitations for inclusion of records in the register. All randomised clinical trials focusing on general physical health advice for people with serious mental illness.. We extracted data independently. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference (MD) between groups and its 95% CI. We employed a fixed-effect model for analyses. We assessed risk of bias for included studies and created 'Summary of findings' tables using GRADE. Seven studies are now included in this review. For the comparison of physical healthcare advice versus standard care we identified six studies (total n = 964) of limited quality. For measures of quality of life one trial found no difference (n = 54, 1 RCT, MD Lehman scale 0.20, CI -0.47 to 0.87, very low quality of evidence) but another two did for the Quality of Life Medical Outcomes Scale - mental component (n = 487, 2 RCTs, MD 3.70, CI 1.76 to 5.64). There was no difference between groups for the outcome of death (n = 487, 2 RCTs, RR 0.98, CI 0.27 to 3.56, low quality of evidence). For service use two studies presented favourable results for health advice, uptake of ill-health prevention services was significantly greater in the advice group (n = 363, 1 RCT, MD 36.90, CI 33.07 to 40.73) and service use: one or more primary

    We consider efficient methods for computing solutions to and estimating uncertainties in dynamic inverse problems, where the parameters of interest may change during the measurement procedure. Compared to static inverse problems, incorporating prior information in both space and time in a Bayesian framework can become computationally intensive, in part, due to the large number of unknown parameters. In these problems, explicit computation of the square root and/or inverse of the prior covariance matrix is not possible, so we consider efficient, iterative, matrix-free methods based on the generalized Golub-Kahan bidiagonalization that allow automatic regularization parameter and variance estimation. We demonstrate that these methods for dynamic inversion can be more flexible than standard methods and develop efficient implementations that can exploit structure in the prior, as well as possible structure in the forward model. Numerical examples from photoacoustic tomography, space-time deblurring, and passive seismic tomography demonstrate the range of applicability and effectiveness of the described approaches. Specifically, in passive seismic tomography, we demonstrate our approach on both synthetic and real data. To demonstrate the scalability of our algorithm, we solve a dynamic inverse problem with approximately 43 000 measurements and 7.8 million unknowns in under 40 s on a standard desktop.

  10. A general approach to regularizing inverse problems with regional data using Slepian wavelets

    Science.gov (United States)

    Michel, Volker; Simons, Frederik J.

    2017-12-01

    Slepian functions are orthogonal function systems that live on subdomains (for example, geographical regions on the Earth’s surface, or bandlimited portions of the entire spectrum). They have been firmly established as a useful tool for the synthesis and analysis of localized (concentrated or confined) signals, and for the modeling and inversion of noise-contaminated data that are only regionally available or only of regional interest. In this paper, we consider a general abstract setup for inverse problems represented by a linear and compact operator between Hilbert spaces with a known singular-value decomposition (svd). In practice, such an svd is often only given for the case of a global expansion of the data (e.g. on the whole sphere) but not for regional data distributions. We show that, in either case, Slepian functions (associated to an arbitrarily prescribed region and the given compact operator) can be determined and applied to construct a regularization for the ill-posed regional inverse problem. Moreover, we describe an algorithm for constructing the Slepian basis via an algebraic eigenvalue problem. The obtained Slepian functions can be used to derive an svd for the combination of the regionalizing projection and the compact operator. As a result, standard regularization techniques relying on a known svd become applicable also to those inverse problems where the data are regionally given only. In particular, wavelet-based multiscale techniques can be used. An example for the latter case is elaborated theoretically and tested on two synthetic numerical examples.

    Positive mental health (PMH) is an integral and essential component of health that encompasses emotional, psychological and social well-being. The Keyes' two continua model of mental health and illness posits that mental health status is not merely the absence of mental health problems, and it can be enhanced regardless of a diagnosis of mental illness. The present study hypothesized that mentally ill patients with higher levels of PMH would be associated with better life satisfaction and general functioning. 218 outpatients with affective disorders at a tertiary psychiatric hospital were recruited and administered the multidimensional Positive Mental Health instrument, which was validated and developed in Singapore to measure PMH. Depression and anxiety severity were also assessed. Associations of positive mental health with life satisfaction and general functioning were investigated in linear regression models. PMH scores varied largely within patients with depressive and anxiety disorders but did not differ statistically across the two diagnoses, except for emotional support. PMH was associated with both life satisfaction and general functioning with little evidence of confounding by sociodemographic and clinical status. The cross-sectional design of the study could not examine causal relationships. Findings may be restrictive to treatment-seeking population with specific affective disorders. Our study provides evidence to support the notion that a good mental health state is not simply the absence of a mental disorder. Mentally ill patients can also have high levels of PMH that possibly have a moderating or mediating effect on the relationship between patients' clinical symptoms and life satisfaction or general functioning.

    Full Text Available Objectives: To assess five-year changes in health behaviours in later life and associations with onset of chronic health problems. The results may inform policy and interventions to promote healthy life years in ageing populations.Methods: Data are derived from the Norwegian study on Life-course, Ageing and Generation (NorLAG, a five-year (2002-2007 panel survey comprising a nation wide community sample. The present analyses include a sample of 1,019 respondents aged 60 years and older. Five-year changes in smoking, alcohol use, physical exercise and Body Mass Index (BMI are assessed according to prevalent and incident chronic health problems. Multivariate logistic analyses of “healthy” behavioural changes are conducted.Results: A total of 453 respondents (45% reported at least one chronic condition and 13% (N=133 reported onset of chronic conditions in the course of the past five years. Over a five-year period, there was an overall reduction in smoking rates and a decrease in regular physical activity. Alcohol consumption in older people slightly increased over time, but the incidence of chronic health problems tended to reduce alcohol intake. Older persons experiencing chronic health problems were less likely to initiate physical activity.Conclusions: The results provide limited support for the assumption that the onset of a chronic health condition triggers improved health behaviours. This suggests that the health care system could do more in targeting a potential “window of opportunity” for individuals to adopt new healthy behaviours in later life.

    Zalaletdinov, R. M.

    1998-04-01

    The averaging problem in general relativity is briefly discussed. A new setting of the problem as that of macroscopic description of gravitation is proposed. A covariant space-time averaging procedure is described. The structure of the geometry of macroscopic space-time, which follows from averaging Cartan's structure equations, is described and the correlation tensors present in the theory are discussed. The macroscopic field equations (averaged Einstein's equations) derived in the framework of the approach are presented and their structure is analysed. The correspondence principle for macroscopic gravity is formulated and a definition of the stress-energy tensor for the macroscopic gravitational field is proposed. It is shown that the physical meaning of using Einstein's equations with a hydrodynamic stress-energy tensor in looking for cosmological models means neglecting all gravitational field correlations. The system of macroscopic gravity equations to be solved when the correlations are taken into consideration is given and described.

    The work presented in this paper is concerned with the development of an efficient MG algorithm for the solution of an elliptic, generalized eigenvalue problem. The application is specifically applied to the multigroup neutron diffusion equation which is discretized by utilizing the Nodal Expansion Method (NEM). The underlying relaxation method is the Power Method, also known as the (Outer-Inner Method). The inner iterations are completed using Multi-color Line SOR, and the outer iterations are accelerated using Chebyshev Semi-iterative Method. Furthermore, the MG algorithm utilizes the consistent homogenization concept to construct the restriction operator, and a form function as a prolongation operator. The MG algorithm was integrated into the reactor neutronic analysis code NESTLE, and numerical results were obtained from solving production type benchmark problems.

    Full Text Available Improving mental health and reducing the burden of mental illness are complementary strategies which, along with the treatment and rehabilitation of people with mental disorders, significantly improve population health and well-being. A Institute of Medicine report describes a range of interventions for mental disorders that included treatment and maintenance, reserving the term “prevention” for efforts that occur before onset of a diagnosable disorder. Mental health problems affect 10&#8211;20% of children and adolescents worldwide. Despite their relevance as a leading cause of health-related disability and their long lasting consequences, the mental health needs of children and adolescents are neglected. Early intervention can help reduce the significant impacts that children and adolescents with serious mental health problems may experience. Screening is the first step in early intervention, recognizing emotional and behavioral problems and providing help at an early stage. It is essential to implement early intervention in a sensitive and ethical manner to avoid any of the negative outcomes.

    Full Text Available Digital technologies have opened a large set of opportunities for new electronic services (e-commerce, e-health, e-studies etc.. There are many considerations that need to be made when programmers are building new application software or system software. The software needs to be attractive enough that people want to look at it. It also needs to contain all necessary information that developers want to share with their readers (customers, users in order to help them achieve the objective for which they came to their website, use their software, or interact with their teaching packages. The oversupply of e-services products has created a need for usability research and development. “Usability means making products and systems easier to use, and matching them more closely to user needs and requirements”. Usability is a key concept of the human-computer interface and is concerned with making computer systems easy to learn and easy to use through a user-centered design process. The in-depth understanding of usability concepts and processes are critical for large-scale acceptance of new e-services and knowledge productivity. Poorly designed software can be extremely annoying to users. Smith and Mayes state that „usability is now recognised as a vital determining factor in the success of any new computer system or computer-based service”. Studies have shown that the main health problems of computer users are repetitive strain injuries, visual discomfort and stress-related disorders. Beside other risk factors, such as poor workstation design, uncomfortable work postures, long hours of computer use every day, stress, etc., also poor design and usability of the computer systems, as well as computer technical problems, add to the pressure felt by the user, which may in turn cause stress-related disorders.

    Background General practitioners (GPs) often see patients presenting with mental health problems, but their training regarding mental health treatment varies. GPs' communication skills are of particular importance in these consultations, and communication skills training of GPs has been found to improve patients' mental health. To tailor a communication skills training by basing it on GPs' learning needs and self-efficacy, thereby maximising learning, we conducted a questionnaire study.

    1973-01-01

    This paper is divided into three parts. Part A presents a historical survey of the development of the system, a brief description of its features and, finally, a critical assessment. ALAM and CLAM have been used in many problems in General Relativity; the vast majority of these belong to a set of standard calculations termed ''metric applications''. However, four large non-standard applications have been attempted successfully and these are described in Part B. CAMAL is the only other system which has been used extensively for work in relativity. CAMAL has played an important role in two research projects and details of these are given in Part C

    A french and an american Ocean General Circulation Models for deep-sea disposal of radioactive wastes are compared on a benchmark test problem. Both models are three-dimensional. They solve the hydrostatic primitive equations of the ocean with two different finite difference techniques. Results show that the dynamics simulated by both models are consistent. Several methods for the running of a model from a known state are tested in the French model: the diagnostic method, the prognostic method, the acceleration of convergence and the robust-diagnostic method

    The theory of generalized Bessel functions has found significant applications in the analysis of radiation phenomena, associated with charges moving in magnetic devices. In this paper we exploit the monomiality principle to discuss the theory of two-variable Laguerre polynomials and introduce the associated Laguerre-Bessel functions. We study their properties (addition and multiplication theorems, generating function, recurrence relations and so on) and discuss the link with the ordinary case. The usefulness of the obtained results to treat problems relevant to the paraxial propagation of electromagnetic waves is also discussed.

    2009-01-01

    Motivated by the important role played by the phase of the fermion determinant in the investigation of the sign problem in lattice QCD at nonzero baryon density, we derive an analytical formula for the average phase factor of the fermion determinant for general topology in the microscopic limit of chiral random matrix theory at nonzero chemical potential, for both the quenched and the unquenched case. The formula is a nontrivial extension of the expression for zero topology derived earlier by Splittorff and Verbaarschot. Our analytical predictions are verified by detailed numerical random matrix simulations of the quenched theory.

    Full Text Available Abstract Background A Community health assessment (CHA involves the use of Geographic Information Systems (GIS in conjunction with other software to analyze health and population data and perform numerical-spatial problem solving. There has been little research on identifying how public health professionals integrate this software during typical problem solving scenarios. A better understanding of this is needed to answer the "What" and the "How". The "What" identifies the specific software being used and the "How" explains the way they are integrated together during problem solving steps. This level of understanding will highlight the role of GIS utilization during problem solving and suggest to developers how GIS can be enhanced to better support data analysis during community health assessment. Results An online survey was developed to identify the information technology used during CHA analysis. The tasks were broken down into steps and for our analysis these steps were categorized by action: Data Management/Access, Data Navigation, Geographic Comparison, Detection of Spatial Boundaries, Spatial Modelling, and Ranking Analysis. 27 CHA professionals completed the survey, with the majority of participants (14 being from health departments. Statistical software (e.g. SPSS was the most popular software for all but one of the types of steps. For this step (detection of spatial boundaries, GIS was identified as the most popular technology. Conclusion Most CHA professionals indicated they use statistical software in conjunction with GIS. The statistical software appears to drive the analysis, while GIS is used primarily for simple spatial display (and not complex spatial analysis. This purpose of this survey was to thoroughly examine into the process of problem solving during community health assessment data analysis and to gauge how GIS is integrated with other software for this purpose. These findings suggest that GIS is used more for spatial

    2009-12-01

    The Problem of Application investigates the multiple viewpoints in defining a critical aesthetic in applied arts practice. Amongst organisations, participants, and facilitators there are varying wants and needs in any creative project with an educational agenda. The product of arts based health initiatives often seek to inform and educate, whereby an aesthetic standard may seem contrary to this participatory approach. This research maintains that an aesthetic approach is a lively portion of the collaborative dialogue, which requires interrogation and consideration for a successful outcome. Through the analysis of a participatory arts project completed in West Africa addressing youth issues and HIV/AIDS, The Problem of Application seeks to uncover the multiple facets surrounding the defining of aesthetics in applied practice. The project entitled Youth Visions: Transforming our Futures Together worked with students aged 17-21 to develop an outdoor mural and a live performance inspired by the traditions of local festivals. With an anthropological approach to aesthetic criticism, Youth Visions revealed the multiple layers that define our focus of appreciation.

    International Nuclear Information System (INIS)

    Mielke, E.W.

    1977-01-01

    Conformal techniques are reviewed with respect to applications to the initial-value problem of general relativity. Invariant transverse traceless decompositions of tensors, one of its main tools, are related to representations of the group of 'conformeomorphisms' acting on the space of all Riemannian metrics on M. Conformal vector fields, a kernel in the decomposition, are analyzed on compact manifolds with constant scalar curvature. The realization of arbitrary functions as scalar curvature of conformally equivalent metrics, a generalization of Yamabe's (Osaka Math. J.; 12:12 (1960)) conjecture, is applied to the Hamiltonian constraint and to the issue of positive energy of gravitational fields. Various approaches to the solution of the initial-value equations produced by altering the scaling behaviour of the second fundamental form are compared. (author)

    2014-01-01

    Many authors have presented studies of multi-choice stochastic transportation problem (MCSTP) where availability and demand parameters follow a particular probability distribution (such as exponential, weibull, cauchy or extreme value). In this paper an MCSTP is considered where availability and demand parameters follow general form of distribution and a generalized equivalent deterministic model (GMCSTP) of MCSTP is obtained. It is also shown that all previous models obtained by different authors can be deduced with the help of GMCSTP. MCSTP with pareto, power function or burr-XII distributions are also considered and equivalent deterministic models are obtained. To illustrate the proposed model two numerical examples are presented and solved using LINGO 13.0 software package.

  7. Some aspects of the inverse problem for general first order systems

    International Nuclear Information System (INIS)

    Sarlet, W.; Cantrijn, F.

    1978-01-01

    In this paper we investigate the most general systems of first-order ordinary differential equations which satisfy the integrability conditions of the inverse problem for canonical formulations, i.e., are derivable from a variational principle. It is shown that they have a structure which is invariant under arbitrary coordinate-transformations. A special class of transformations, called identity-isotopic transformations, is described. It is illustrated how these transformations share all properties with classical canonical transformations except one: the solutions of the system, viewed as transformations from the set of initial values, generally are not identity-isotopic. This failure is shown to be due to the explicit time-dependence of the functions which characterise the system, and the special role of this time-dependence is further clarified using the possibility of a reduction to conventional Hamiltonian systems. All properties are derived here within the framework of an analytic treatment of a system of differential equations

    The aim was to investigate the prevalence of health problems and work environment problems and how these are associated with subjective production loss among women and men at an academic workplace. An additional aim was to investigate whether there were differences between women and men according to age group, years at current workplace, academic rank or managerial position. A questionnaire was sent in 2011 to all employees at a Swedish university (n = 5144). Only researchers and teachers were included in the study (n = 3207). Spearman correlations were performed to investigate differences in health and work environment problems. Employees who reported having experienced work environment or health problems in the previous seven days (n = 1475) were included in the analyses in order to investigate differences in subjective production loss. This was done using Student's t-test, One-way Anova and generalized linear models. The response rate was 63% (n = 2022). A total of 819 academic staff (40% of the population) reported experiencing either health problems, work environment problems or both during the previous seven days. The prevalence of health problems only or a combination of work environment and health problems was higher among women than men (p-value ˂0.05). This was especially the case for younger women, those in lower academic positions and those who had worked for fewer years at their current workplace. No difference was found for work environment problems. The majority of the employees who reported problems said that these problems affected their ability to perform at work (84-99%). The average production loss varied between 31 and 42% depending on the type of problem. Production loss due to health-related and work-environment related problems was highest among junior researchers and managers. No significant difference between men and women was found in the level of production loss. Subjective production loss in academia can be associated

  9. The Meaning and Predictive Value of Self-rated Mental Health among Persons with a Mental Health Problem.

    2018-06-01

    Self-rated health is a valid measure of health that predicts quality of life, morbidity, and mortality. Its predictive value reflects a conceptualization of health that goes beyond a traditional medical model. However, less is known about self-rated mental health (SRMH). Using data from the Medical Expenditure Panel Survey ( N = 2,547), we examine how rating your mental health as good-despite meeting criteria for a mental health problem-predicts outcomes. We found that 62% of people with a mental health problem rated their mental health positively. Persons who rated their mental health as good (compared to poor) had 30% lower odds of having a mental health problem at follow-up. Even without treatment, persons with a mental health problem did better if they perceived their mental health positively. SRMH might comprise information beyond the experience of symptoms. Understanding the unobserved information individuals incorporate into SRMH will help us improve screening and treatment interventions.

    2005-01-01

    The theory of generalized thermoelasticity, based on the theory of Lord and Shulman with one relaxation time, is used to study the electro-magneto-thermo-elastic interactions in an infinitely long perfectly conducting solid cylinder subjected to a thermal shock on its surface when the cylinder and its adjoining vacuum is subjected to a uniform axial magnetic field. The cylinder deforms because of thermal shock, and due to the application of the magnetic field, there result an induced magnetic and an induced electric field in the cylinder. The Maxwell's equations are formulated and the generalized electro-magneto-thermo-elastic coupled governing equations are established. By means of the Laplace transform and numerical Laplace inversion the problem is solved. The distributions of the considered temperature, stress, displacement, induced magnetic and electric field are represented graphically. From the distributions, it can be found the electromagnetic-thermoelastic coupled effects and the wave type heat propagation in the medium. This indicates that the generalized heat conduction mechanism is completely different from the classic Fourier's in essence. In generalized thermoelasticity theory heat propagates as a wave with finite velocity instead of infinite velocity in medium. (authors)

    2016-05-01

    Full Text Available The present paper provides an extensive literature review on water related health issues in Central Asia. Even though the per capita amount of available freshwater is substantial in all Central Asian states the uneven distribution in time and space creates problems for water availability. Due to this, the Central Asian economies are developing under increasing water deficiency. The degradation of water supply systems and sewage treatment plants is often severe leading to potentially high water loss rates and inadequate accessibility to safe water supply. In this context, rural areas are the most affected. Low tariffs in combination with absent metering and low collection rates for water fees mean that operation and maintenance costs for basic services of water supply and sanitation are not covered. Unsafe water supply contains both microbiological and non-microbiological contaminants. Helminthiasis and intestinal protozoa infections are of considerable public health importance in Central Asia. Agricultural and industrial pollution is especially affecting downstream areas of Amu Darya and Syr Darya rivers. In large areas copper, zinc, and chromium concentrations in water exceed maximum permissible concentration. Thus, there is an urgent need to strengthen the environmental monitoring system. Small-scale water supply and sanitation systems need to be developed in line with more efficient public spending on these.

    Full Text Available A survey of sleep schedules, sleep health, and the impact on school performance was conducted in 585 adolescents in a high school in China. A high level of early and circadian-disadvantaged sleep/wake schedules during weekdays was observed. Significantly shorter sleep duration on weekdays was reported ( P < 0.0001. Older teenagers slept significantly less than the younger teenagers ( P < 0.0001. Complaints of inadequate sleep and sleepiness during weekdays were prevalent. Night awakenings were reported in 32.2% of students. Students with a sleep length of less than 7 hours, complaint of inadequate sleep, or excessive daytime sleepiness during weekdays were more likely to report an adverse effect of poor sleep on performance. The present observations are qualitatively similar to those reported in our study in American adolescents, particularly with respect to Chinese adolescents exhibiting a similar sleep deficiency on weekdays. We concluded that sleep deficiency and sleep health problems were prevalent in the participating adolescents in China, and were perceived to adversely affect school performance.

    2006-01-01

    Long-distance travel to provide mental health services for deaf people has implications for efficiency, safety, and equality of service. However, uptake of Telemental Health (TMH) has been slow in both deaf and general mental health services. A quantitative study was used to investigate access to TMH and whether staff confidence, experience, or demographics affect TMH use. It was concluded that staff in neither deaf mental health services nor general mental health services had adequate knowledge of or access to TMH. Staff expressed concerns over TMH's appropriateness in their work. Previous use of videoconferencing was assosciated significantly with confidence, but previous use of videophones was not. Neither staff in deaf services nor deaf staff were more experienced with or more confident about videoconferencing, whereas, within deaf services, deaf staff were significantly more confident about videophone use. Training implications are discussed.

    The development of an animal health barometer, an instrument to measure the general health of the Belgian livestock population on a yearly basis and to monitor its evolution over time, is described. The elaboration of a set of 13 animal health indicators (AHIs) as the basis for the animal health barometer is discussed. These indicators were weighted by experts - including scientists, policy makers and agro-industrial representatives - to determine their relative weight in the barometer. The result of the barometer is expressed as a comparison with a previous year. Based on the results of the 13 AHIs, it is concluded that general animal health in Belgium shows a positive evolution since 2008. The animal health barometer provides a composite view of the status of livestock health in Belgium and is a tool to communicate in an intelligible, comprehensible manner on aspects of animal health to consumers and professional stakeholders in the animal production and food chain. Together with the food safety barometer (Baert et al., 2011. Food Res. Int. 44, 940) and the plant health barometer (Wilmart et al., 2014. Eur. J. Plant Pathol. doi: 10.1007/s10658-014-0547-x), the animal health barometer is one of the three instruments to provide a holistic view on the overall status of the safety of the food chain in Belgium.

    On the basis of the literature review the critical analysis of the recommendations (the letter of Ministry of Health of Russia from 6/11/2012 N 14-1/10/2-3508) on occupation noise-induced hearing loss (HL) assessment is presented. Need of more strict criteria of HL assessment for workers, than for the general population according to ICF (WHO, 2001), in order to avoid growth of accidents and injury rate is proved. The illegitimacy of a deduction of statistical presbiacusia values from individual audiograms as human rights violation is stressed. Some terminological defects are noted. It is necessary to cancel recommendations and to develop the sanitary norms or state standard with the program of hearing conservation at work.

  17. AN ACCURATE ORBITAL INTEGRATOR FOR THE RESTRICTED THREE-BODY PROBLEM AS A SPECIAL CASE OF THE DISCRETE-TIME GENERAL THREE-BODY PROBLEM

    For the restricted three-body problem, we propose an accurate orbital integration scheme that retains all conserved quantities of the two-body problem with two primaries and approximately preserves the Jacobi integral. The scheme is obtained by taking the limit as mass approaches zero in the discrete-time general three-body problem. For a long time interval, the proposed scheme precisely reproduces various periodic orbits that cannot be accurately computed by other generic integrators

    War victims are regarded as one of the highest risk groups for mental disturbances. This study investigated the effects of the Darfur conflict on mental health of 430 internally displaced persons (IDPs) from three camps located around Fasher and Nyala towns. A stratified random sampling technique was used to select participants. Male participants represented 50.6% of the sample while female participants represented 49.4%. The Posttraumatic Stress Disorder Checklist and the General Health Questionnaire (GHQ-28) were used in addition to a questionnaire measuring demographic variables and living conditions. It was hypothesized that high prevalence of posttraumatic stress disorder (PTSD) symptoms and of nonpsychotic psychiatric symptoms will be evident. Results showed a high dissatisfaction rate (72%) with living conditions among IDPs. There was also high prevalence of PTSD (54%) and general distress (70%) among IDPs. Female participants showed more somatic symptoms than their male counterparts. Married participants were more distressed, anxious, and showed more social dysfunction, while single ones reported more avoidance symptoms. Significant differences related to date of displacement were found in PTSD and hyperarousal. The group of IDPs displaced in 2003 scored higher on these scales than those displaced in 2004 and 2005. There was also significant difference related to date of displacement in distress, somatic symptoms, depression, anxiety, and social dysfunction. IDPs displaced in 2003 scored higher on these scales. Results are discussed in light of the study hypotheses and previous findings. It is concluded that three factors might affect the dissatisfaction of IDPs with living conditions inside camps. These are: lack of employment, unsuitability of food items, and lack of security around camps. It was recommended that psychological support services should be among the prime relief services provided by aid agencies.

    To investigate the circumstances that led general practitioners to refer dementia sufferers and their carers to community support services. Qualitative study using semi-structured interviews, carried out between 1 September 1999 and 30 April 2000. 21 live-in carers of patients with dementia referred for the first time to a Western Australian metropolitan Aged Care Assessment Team, and 19 of their referring general practitioners. Most referrals occurred after the carers had been experiencing carer stress, and were precipitated by crisis situations. Carers failed to discuss their difficulties with the referring GP for a variety of reasons, including the belief that they should cope because it was their duty. The doctors found it difficult to know how the carers were coping or when to intervene, and some carers tended to resist their attempts to help. Time constraints were a significant problem for both groups. Attitudinal barriers in both carers of patients with dementia and GPs, combined with time constraints, often lead to inadequate assessment of carer problems. While it is important that strategies to improve communication between carers and GPs are developed, it would be sensible for GPs to assume that dementia carers are at risk of carer stress and should be encouraged to use community care services.

  20. Efficient Greedy Randomized Adaptive Search Procedure for the Generalized Regenerator Location Problem

    Full Text Available Over the years, there has been an evolution in the manner in which we perform traditional tasks. Nowadays, almost every simple action that we can think about involves the connection among two or more devices. It is desirable to have a high quality connection among devices, by using electronic or optical signals. Therefore, it is really important to have a reliable connection among terminals in the network. However, the transmission of the signal deteriorates when increasing the distance among devices. There exists a special piece of equipment that we can deploy in a network, called regenerator, which is able to restore the signal transmitted through it, in order to maintain its quality. Deploying a regenerator in a network is generally expensive, so it is important to minimize the number of regenerators used. In this paper we focus on the Generalized Regenerator Location Problem (GRLP, which tries to innd the minimum number of regenerators that must be deployed in a network in order to have a reliable communication without loss of quality. We present a GRASP metaheuristic in order to innd good solutions for the GRLP. The results obtained by the proposal are compared with the best previous methods for this problem. We conduct an extensive computational experience with 60 large and challenging instances, emerging the proposed method as the best performing one. This fact is innally supported by non-parametric statistical tests.
