DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n1p40 There is evidence demonstrating that prolonged sitting time is relevant risk factors for metabolic and cardiovascular disorders. The aim of this study was to identify the discriminatory power and propose cumulative sitting time cutoff points for overweight, obesity, abdominal obesity and lipid disorders in nursing university students. A cross-sectional study of 137 women, nursing students from a public university in Salvador, Bahia, Brazil. Data were obtained by applying specific forms, laboratory and anthropometric measurements. The predictive power and cutoff points of sitting time for the outcomes of interest were identified by receiver operating characteristic curves (ROC). A 95% confidence interval was established. Sitting time for a day of the week was a good discriminator of abdominal obesity: area under the ROC curve (AUC) = 0.66 (0.57-0.75). No AUC with statistical significance were found to discriminate overweight and total obesity. Sitting time over the weekend showed no discriminatory power for overweight, obesity or abdominal obesity. Sitting time during the week or weekend did not discriminate lipid abnormalities. Sitting time for 8 hours or more a day during the week discriminates the presence of abdominal obesity. The sitting time during the week of 8 hours accumulated per day discriminates abdominal obesity in undergraduate nursing. It is suggested that educational institutions establish measures to encourage a reduction in this sedentary behavior.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n1p50 International studies have shown that motor coordination was inversely associated with adiposity, and directly associated with other health outcomes. However, there are few national studies addressing this issue and the results are divergent. The aim of this study was to analyse the relationship between physical activity and body mass index (BMI) with the level of motor coordination performance in children. This cross-sectional study was performed with children aged 5-7 years old. The level of motor performance was evaluated by normative data of the motor quotients assessed by KTK test. BMI was calculated by body weight and height. The level of physical activity was assessed by a questionnaire applied by interviewers with parents. Statistical analysis was performed by Spearman and Pearson test, and multiple linear regression. The sample included 665 children with mean age of 6.29 (± 0.75) years old, and 52.6% were male. It was verified which total motor quotient (TMQ) was directly related to physical activity score (0.096; p = 0.013) and inversely related to BMI (-0.284; p<0.001). The relationship between BMI and TMQ was moderated by family income. BMI was inversely related to the level of motor performance, and the score of physical activity was directly related to the level of motor performance in children in a higher family income.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n2p150 The human being does not have static development throughout life. From conception to death, there are physical, psychological, social transformations and modifications, being vulnerable to restrictions. Interventions seek to reduce the effects of these restrictions, as children and adolescents are influenced by impoverished motor experiences in the family and school environment. The aim of this study was to evaluate the effects of an intervention program on 8-10-year-old schoolchildren in the public school system of Matinhos/PR, Brazil. Ninety-one 8-10-year-old schoolchildren from the 3rd, 4th and 5th grades were evaluated by the Motor Development Scale (MDS). Fifty-four of them presented risk of delay. Of these, 27 who performed weekly physical education classes were randomized into Control Group (CG), and 27 (Experimental Group - EG) to a psychomotor intervention program twice a week for four weeks. After interventions, EG and CG were reassessed. In the analysis of the General Motor Quotient (GMQ), it was verified that in all grades, EG presented a significant increase compared to the moment of evaluation, which was not observed among children in the CG. There was a significant increase in the averages in the reevaluation of CG and GE, however, EG presented significant differences in the Fine Motor and Balance dimensions. Intervention improved GMQ, Fine Motor and Balance compared to traditional Physical Education class.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p385 The aim of this study was to investigate the effects of 12 weeks of aerobic and resistance training on the maximal and submaximal cardiorespiratory fitness of young people with Down Syndrome (DS). Forty-one individuals of both sexes with Down syndrome (age, 15.51±2.70 y) were divided into three groups: CG (control group) with 10 participants; ATG group (aerobic training group) with 16 participants; and RTG (resistance training group) with 15 participants. The training program lasted 12 weeks, with frequency of 3 days a week for ATG and two RTG, and duration of 50 minutes per session. Aerobic training consisted of exercise on a treadmill/bike at intensity between 50 and 70% of reserve heart rate, while resistance training was composed of nine exercises performed on three sets of 12 maximum repetitions for each exercise. Aerobic and resistance training were not able to increase peak oxygen uptake. However, there was an increase in the maximum ventilation and a decrease of submaximal heart rate only for groups who participated in the training program. Moreover, the aerobic group increased work capacity after training. Training programs led to an improvement in cardiac efficiency during submaximal activities and increased maximum ventilation, which demonstrates a cardiorespiratory improvement.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p406 Considering that handball is a sport that requires physical contact, jumps, and fast movements, it is relevant to create prevention strategies to avoid injuries. It is known that better proprioceptive conditions and muscular balance are associated with reductions in sport injuries. The aim of this study was to analyse the cumulative effect of a twelve-week FIFA11+ training program in addition to conventional handball training on postural balance and isokinetic strength of the knee joint in female handball athletes. Twenty-one athletes (aged 11-14 years) were assessed and divided into two groups: intervention group (IG), composed of girls who practiced FIFA11+ associated with regular handball training, and control group (CG) composed of girls who participated only in team training. Both groups were assessed at pre- and post-intervention including knee muscular power using isokinetic dynamometer. Postural balance was assessed through computerized dynamic posturography, with sensory organization test (SOT), analysis of sensorial systems, and unilateral test. IG performed the FIFA11+ program exercises, twice a week, with sessions lasting 40 minutes on average, during 12 weeks. The results demonstrate an improvement in postural balance in IG group at condition 5 of SOT, and in the use of vestibular system at post-intervention, which did not occur in CG. As far as knee isokinetic muscular power is concerned, both groups showed improvements. In conclusion, the practice of FIFA11+ in addition to conventional handball training demonstrated important contributions on the postural balance of young players.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p436 Inadequate levels in health-related physical fitness components are associated with early cardiovascular mortality in adult life. The aim of this study was to analyze the association between clusters of negative physical fitness indicators with sociodemographic and lifestyle variables in adolescents. The survey was conducted with 866 students (14-19 years) from public schools of São José, Santa Catarina, Brazil. Aerobic fitness was assessed by the modified Canadian aerobic fitness test; muscle strength was measured by handgrip dynamometer; flexibility was assessed by the sit-and-reach test; body fat was measured by the sum of triceps and subscapular skinfolds. Sociodemographic and lifestyle variables were verified by questionnaire. The simultaneity of behaviors was evaluated by the ratio between observed and expected prevalence of inadequate physical fitness levels. The combination of negative physical fitness indicators was analyzed through multinomial logistic regression. The prevalence observed for the simultaneity of four negative physical fitness indicators was 30% higher than expected. Female adolescents were more susceptible to the presence of two, three and four negative physical fitness indicators. Adolescents who presented risk behavior in relation to screen time were more likely to present one, three and four negative physical fitness indicators. Female gender and risk behavior in relation to screen time were factors associated with the simultaneity of negative physical fitness indicators.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p493 The aim of this study was to estimate the prevalence of stages of behavior change (SBC) for physical activity and to verify the associated demographic and economic factors, in adolescents from the Amazon. A total of 2,517 adolescents (aged 14-19 years) from public high schools participated of the study. SBC for physical activity, demographic (sex, age, school year, school shift and residence area) and economic factors (occupational status, family income and maternal schooling) were investigated. The associations between SBC and independent variables were tested by multinomial logistic regression. Most adolescents were in the maintenance stage (40.8%) and the minority was in pre-contemplation stage (9.0%). Female adolescents were more likely of being in the action (OR=1.44; CI95%=1.14-1.81), preparation (OR=2.71; CI95%=2.14-3.44), contemplation (OR=2.89; CI95%=2.25-3.69) and pre-contemplation (OR=2.91;CI 95%=2.16-4.00) stages compared to male adolescents. Adolescents aged 16-17 years were less likely of being in the action stage (OR=0.71; CI95%=0.53-0.94) and those aged 18-19 years were more likely of being in the preparation stage (OR=1.50; CI95%=1.04-2.16) compared to those aged 14-15 years. Family income of six minimum wages or more was associated to higher chances of being in the action (OR=2.09; CI95%=1.38-3.17), preparation (OR=2.02; CI95%=1.31- 3.12) and contemplation (OR=1.87; IC95%=1.18-2.95) stages. Adolescents who worked were less likely of being in the pre-contemplation stage (OR=0.45; CI95%=0.27-0.74), compared to those who do not work. Most of adolescents were in the maintenance stage for physical activity. The factors associated to SBC were female sex, age groups of 16-17 years and 18-19 years, income of six minimum wages or more and work.
Monitoring small reservoirs' storage with satellite remote sensing in inaccessible areas

Published: December 2017

Abstract. In river basins with water storage facilities, the availability of regularly updated information on reservoir level and capacity is of paramount importance for the effective management of those systems. However, for the vast majority of reservoirs around the world, storage levels are either not measured or not readily available due to financial, political, or legal considerations. This paper proposes a novel approach using Landsat imagery and digital elevation models (DEMs) to retrieve information on storage variations in any inaccessible region. Unlike existing approaches, the method does not require any in situ measurement and is appropriate for monitoring small, and often undocumented, irrigation reservoirs. It consists of three recovery steps: (i) a 2-D dynamic classification of Landsat spectral band information to quantify the surface area of water, (ii) a statistical correction of DEM data to characterize the topography of each reservoir, and (iii) a 3-D reconstruction algorithm to correct for clouds and Landsat 7 Scan Line Corrector failure. The method is applied to quantify reservoir storage in the Yarmouk basin in southern Syria, where ground monitoring is impeded by the ongoing civil war. It is validated against available in situ measurements in neighbouring Jordanian reservoirs. Coefficients of determination range from 0.69 to 0.84, and the normalized root-mean-square error from 10 to 16 % for storage estimations on six Jordanian reservoirs with maximal water surface areas ranging from 0.59 to 3.79 km2.
Does nonstationarity in rainfall require nonstationary intensity–duration–frequency curves?
Authors: Ganguli Poulomi , Coulibaly Paulin 
Published: December 2017

Abstract. In Canada, risk of flooding due to heavy rainfall has risen in recent decades; the most notable recent examples include the July 2013 storm in the Greater Toronto region and the May 2017 flood of the Toronto Islands. We investigate nonstationarity and trends in the short-duration precipitation extremes in selected urbanized locations in Southern Ontario, Canada, and evaluate the potential of nonstationary intensity–duration–frequency (IDF) curves, which form an input to civil infrastructural design. Despite apparent signals of nonstationarity in precipitation extremes in all locations, the stationary vs. nonstationary models do not exhibit any significant differences in the design storm intensity, especially for short recurrence intervals (up to 10 years). The signatures of nonstationarity in rainfall extremes do not necessarily imply the use of nonstationary IDFs for design considerations. When comparing the proposed IDFs with current design standards, for return periods (10 years or less) typical for urban drainage design, current design standards require an update of up to 7 %, whereas for longer recurrence intervals (50–100 years), ideal for critical civil infrastructural design, updates ranging between  ∼ 2 and 44 % are suggested. We further emphasize that the above findings need re-evaluation in the light of climate change projections since the intensity and frequency of extreme precipitation are expected to intensify due to global warming.
Bienestar policial: Una mirada a la salud, a la seguridad ocupacional y a la prevención de los riesgos ocupacionales de los policías en El Salvador
Authors: Coca Muñoz Carlos Alberto , Thomas Argueta María Carolina 
Published: December 2017

Poco se escucha y analiza sobre la protección y el cuido del policía en el ámbito laboral. El imaginario colectivo los considera máquinas incansables y les exige una entrega extraordinaria para aniquilar el crimen. Se soslaya la dimensión laboral y personal del policía, se ignora su cansancio y riesgo a perder la vida, sus aspiraciones personales y preocupaciones familiares. Este estudio se ocupa de explorar la labor de la División de Bienestar Policial de la Policía Nacional Civil, específicamente en materia de salud y seguridad ocupacional, para analizar si sus acciones consideran las disposiciones de la Ley General de Prevención de Riesgos en los Lugares de Trabajo y si así se coadyuva a la instauración de entornos laborales sanos. Las premisas son dos: i) el bienestar laboral supone la ejecución de medidas de salud y seguridad ocupacional; ii) la relación directa entre el bienestar laboral de los policías y el desempeño de sus labores.
Peace, Culture and Communication: “Languaging” Post-conflict Disputes
Authors: Edith Ruth Natukunda-Togboa 
Published: December 2017

Language, which is rarely neutral, shapes perception and behavior. Consequently, it plays an important role in relation to conflict and peace. The language of conflict usually functions on the basis of using differences to promote violence. Interviews conducted on land disputes in the post-conflict context of Northern Uganda, showed that language can be used to reduce these differences and affirm dignity thus diffusing tensions. Our preceding studies of conflict discourse within returnee communities have endeavored to show how language use, by imposing certain misrepresentations as legitimate, undermines efforts of social reintegration, perpetuates conditions of negative peace and can pose a threat of returning to conflict.In this study of Gulu elders dealing with post-conflict disputes, language is perceived as a tool of positive peace. Borrowing from the sociocultural theory of mind and its application to concepts of language, the paper shows how language can foster open and inclusive communication and support the pursuit of peaceful cohabitation within returnee communities. It goes on to demonstrate how language, within the cultural institutions of returnee communities, constitutes power that can be used in “languaging” conflict resolution. According to the study, language has embedded within it actual relations of power, so much so that those who control it exercise an enormous influence on how the communities perceive conflict and peace-building and what behaviors they accept in relation to resolving post-conflict disputes.Consequently, the quick revitalization of traditional arrangements of dispute settlement has been possible in the area of Gulu because language is a strong social institution which has enhanced the efforts of peace maintenance in the Acholi post conflict context. Languaging or talking through disputes as an alternative discourse to conflict should be embraced as a strategy of empowering the voiceless. It is an effective and sustainable cost effective strategy for dealing with cyclic disputes especially when applied as complementary to other dispute settlement approaches.

Objective: To characterize the regional and national variation in prescribing patterns in the Medicare Part D program using machine learning and dimensional reduction visualization methods.
Methods: Using publicly available Medicare Part D claims data, we identified regional and national provider prescribing profile variation with unsupervised clustering and t-distributed stochastic neighbor embedding (t-SNE) dimensional reduction techniques. Additionally, we examined differences between regionally representative prescribing patterns for major metropolitan areas.
Results: Distributions of prescribing volume and medication diversity were highly skewed among over 800,000 Medicare Part D providers, and medical specialties had characteristic prescribing patterns. Although the number of Medicare providers in each state was highly correlated with the number of Medicare Part D enrollees, some states were enriched for providers with >10,000 prescription claims annually. Hierarchical clustering and t-SNE dimension-reduction visualization of drug- or drug-class prescribing patterns revealed that providers cluster strongly based on specialty and sub-specialty, with large regional variations in prescribing patterns. Major metropolitan areas had distinct prescribing patterns that tended to group by major geographical divisions.
Conclusions: There is substantial prescribing variation among providers in Medicare Part D both between and within specialties. Large regional variations in prescribing patterns, particularly among major metropolitan areas, were also seen. Unsupervised clustering and t-SNE dimension-reduction are an effective means to examine variation in provider prescribing patterns, including substantial regional and medical specialty variation.
Health and Safety in Podiatric Medicine

Published: December 2017

Background:Much of the research into health and safety in podiatric medicine to date has focused on measuring particular hazards. This study examines legislative awareness and compliance in Irish podiatric medical practices and aspects of health and safety practice.Methods:Podiatric physicians practicing in Ireland completed a cross-sectional questionnaire survey that included measures of health and safety knowledge and awareness, compliance with legislative requirements, perceived risks, and health status.Results:Of 250 podiatric physicians who were contacted, 101 completed the survey (response rate, 40%). Legislative knowledge and compliance were low among respondents. A Student t test revealed that the use of safety control measures was more frequent among podiatric physicians in practice for less than 20 years (P &lt; .05). Musculoskeletal disorders and back injuries were the most frequently reported health concerns.Conclusions:This study demonstrates the need for interventions to increase awareness of legislative requirements among podiatric physicians as a first step to increase levels of regulatory compliance.
