Resumo O objetivo deste estudo foi avaliar o consumo alimentar, identificar a ingestão de energia e nutrientes da dieta, bem como os hábitos alimentares dos idosos cadastrados no Programa Municipal da Terceira Idade (PMTI), no município de Viçosa-MG. O consumo alimentar foi avaliado em 183 idosos com idade entre 60 e 90 anos, por meio da soma do consumo encontrado entre o Recordatório 24 horas e o questionário de Freqüência Alimentar Semiquantitativo. Para a adequação do consumo de nutrientes e energia, foi utilizado um cálculo baseado na Ingestão Dietética de Referência (DRI). A ingestão energética ficou abaixo da necessidade estimada para quase todos os idosos, observando-se elevada ingestão de energia de fontes lipídicas (52,5%). Verificou-se alta freqüência de inadequação no consumo de vitaminas (vitaminas C, A, B1, B2 e B6). O consumo de cálcio foi 1/3 do valor recomendado. Dos idosos estudados, quase todos apresentaram ingestão energética abaixo da necessidade energética estimada (EER). Observou-se um desbalanceamento na dieta, havendo alta prevalência de inadequação no consumo de proteínas, vitaminas e minerais na alimentação dos idosos estudados.

Published: October 2019

ABSTRACT Objective: to analyze how intensive care nurses practice patient advocacy in view of the need for hospitalization by court order to an intensive care due to bed unviability. Method: analytical exploratory qualitative research. Data were obtained through interviews with 42 nurses, selected via snowball sampling, between January and December 2016. The interviews were analyzed using elements of the Discursive Textual Analysis. Results: two categories emerged: 1) Between obedience to the law and the ethical-moral duty of the intensive care nurse; 2) The position of nurses in the practice of patient advocacy for patients requiring intensive care beds. Conclusions: intensive care nurses exercise sensitivity and moral duty of the care process when defending their patients by informing them of their rights, guiding, acting and talking to and on behalf of patients and their families, valuing care free of judgment and harm to the patient hospitalized by court order.

ABSTRACT Objective: to investigate factors associated with the use and quality of Primary Health Care, as well as the occurrence of pneumonia and diarrhea in children under one year. Method: cross-sectional study conducted with 317 caregivers of 56 Family Health teams from Juazeiro do Norte, Ceará, from August 2014 to October 2015, using the child version of the Primary Care Assessment Tool, child version. Results: in the logistic adjustment, children received assistance (OR: 0.54; 0.32-0.91) and accessibility to the Primary Health Care Unit (OR: 0.49; 0.31-0.76). identified as possible protective factors for episodes of diarrhea. The variables associated with pneumonia were unsatisfactory access (ORaj: 2.13; 95% CI 1.18-3.82), a likely risk factor, and coordination (ORaj: 0.33, 95% CI 0.12-0,94), as a probable protection factor. Conclusion: primary care attendance resulted in a higher chance of avoiding hospitalization for pneumonia, a condition considered sensitive to care in this care model. Complementing family income and children's accessibility to the health unit were protective factors for episodes of diarrhea. The search to ensure the presence and extension of the Primary Health Care attributes has the potential to positively modify the child's health and, therefore, both should be ensured as rights of this population.

ABSTRACT Objective: to identify absenteeism of nursing technicians in an Intensive Care Unit and to verify the association between absenteeism and workload. Method: cross-sectional retrospective study of documentary source and quantitative approach. It was performed in an adult intensive care unit with 4,920 measurements from the Nursing Activities Score in 2017, in order to extract the nursing workload, and control absenteeism, considering the absences recorded in the management register of the department. Descriptive and inferential statistical analysis was performed, dividing the intensive care unit into two groups (ICU I and ICU II), according to team shifts. Results: in the period analyzed, 461 absences were observed, with a higher proportion in ICU II (5.35%, p-value=0.00). This group also had the highest Nursing Activities Score (99.76) average. However, workload and absenteeism showed no statistically significant correlation in the analyzed groups (ICU I, r=0.02 and ICU II, r=0.06). Conclusion: there was no statistically significant association between absenteeism and workload of nursing technicians in the Intensive Care Unit. However, the team with the highest workload was the most absent.

Abstract Introduction: This study is relevant insofar since it provides information on the elements that interfere in the level of physical activity of the elderly that attend the Fitness zone. Objective: Identifying the level of physical activity and its associated factors related to the elderly who usually go to third age fitness centers in Maringá/PR. Method: A cross-sectional study was carried out with 970 elderly users of the Fitness zone of the municipality of Maringá, state of Paraná, Brazil. A sociodemographic questionnaire and the International Physical Activity Questionnaire (IPAQ) was used. The data were analyzed by the Pearson’s Chi-squared, the Binary Logistic Regression and the Hosmer-Lemeshow test (p < 0,05). Results: The data indicates that being married (p = 0,047) and having completed higher education (p = 0,001) is significantly associated with higher physical activity level. The lower use of medication (p = 0,008), the excellent health perception (p = 0,037), and no history of near-falls (p = 0,038) were associated with the physical activity practice. The subjects who had no history of near-falls in the last six months and who did not have osteoporosis were 1.671 [95% CI = 1.009-2.613] and 1.891 [95% CI = 1.008-2.915] times more likely to be active/very active when compared to the elderly who had near-falls in the last semester and who had osteoporosis. Conclusion: It was concluded that sociodemographic variables and health conditions are associated to the physical activity level in the elderly. Further, elderly who reported the absence of a history of near falls and osteoporosis have more chance to be physically active.

Published: October 2019

Abstract Objective: To measure the Quality of Life (QoL) and associated factors in a group of elderly persons receiving care through a health plan operator in the city of São Paulo, Brazil. Method: A cross-sectional study was carried out with 169 elderly persons enrolled in a health plan and who were participants in a program to promote health and prevent risks and diseases. The Bref and Old versions of the World Health Organization Quality of Life (WHOQOL) instruments were adopted for the evaluation of the QoL of the elderly. After descriptive analysis, a comparative analysis was performed through the Student’s t-tests and ANOVA. The Brown-Forsythe test was applied for situations in which no homogeneity was found and the Tukey test for multiple comparisons was applied. Results: The highest mean QoL values were found in the Psychological [72.1 (±14.3)] and Environment [68 (±15.4)] and Intimacy [72.5 (±20.8)] domains, while the worst results were found in the Physical [64.3 (±18)] domain and in the Death and Dying facet [61.2 (±23.2)]. In this group, factors such as obesity, neoplasia and previous hospitalizations were negatively associated with QoL, whereas young elderly, female, widows, carriers of chronic non-communicable diseases and those limited to two morbidities, who practiced physical activity and had clinical care provided by a reference physician had a positive influence. Conclusion: The findings of this research showed high levels of satisfaction with health and QoL, in addition to raising relevant discussions about predictors that influence the QoL of the elderly receiving care from the supplementary sector. It also emphasizes the need for new strategies of action to ensure improvements in the health care of the elderly.

Abstract Objective: To evaluate the effectiveness of a multiple intervention programme for the prevention of falls in older adults from a University of the Third Age (U3A). Method: A quasi-experimental, non-controlled, longitudinal and quantitative study was performed. 69 older adults were allocated into three groups: Control (CG), Physical Exercise (PEG) and Multiple Intervention (MIG). The instruments/tests used were: sociodemographic questionnaire, Geriatric Depression Scale (15-items), Mini-Mental State Examination, Timed-Up and Go (TUG), Sit-to-Stand and Hand-Grip Strength, Falls Efficacy Scale-International and Falls Risk Awareness Questionnaire (FRAQ).The PEG and MIG groups underwent physical training (walking, muscular resistance, and balance) for 16 weeks (2x/week, 60 min/session). In the same period, the MIG also participated in educational sessions (1x/week, 60min/session). Covariance analysis was used for group comparisons. The effect size of the interventions was also calculated. The level of significance was set at p<0.05. Results: 51 older adults (67±6.2 years and 76.3% women), of whom 15 were in the CG, 20 in the PEG and 16 in the MIG, concluded the study. TUG time in both intervention groups was reduced, but FRAQ score improved in the MIG only. Both interventions had a small effect on TUG time, while multiple intervention had a large effect on FRAQ. Conclusion: Multiple intervention brought additional benefits to the older adults from this U3A. In addition to improving balance, the older adults who underwent the multiple intervention increased their knowledge about risk factors for falls.
Drying kinetics and mass transfer properties in the drying of thistle flower
Authors: Guiné Raquel P. F. , Fontes Luísa , Lima Maria João Reis
Published: October 2019

Abstract Thistle flowers, and particularly their stigmas, are used to coagulate milk in the production of a number of traditional Portuguese cheeses due to their high milk-clotting activity provided by the high content of aspartic proteases. The aim of the present work was to determine the mass transfer properties of thistle flower under different drying conditions: natural drying and convective drying. Convective drying took place in a convection chamber set at different temperatures (35 to 65 °C) and the process was terminated when the sample presented a moisture content of about 5% or less. The traditional drying method was also used, placing the thistle flowers in a dry place sheltered from the sun, and leaving them to dehydrate at the variable room temperature. The present work allowed for the conclusion that convective drying was much faster than natural drying, and that the drying rate increased with temperature. The drying curve revealed an initial constant rate period followed by a falling rate. All the five thin layer models tested to fit the experimental data were shown to adequately describe the drying of the thistle flowers, but the best one was the Page model. The drying constant increased with temperature as did the effective diffusivity and the mass transfer coefficient. The results allowed one to estimate the activation energy for moisture diffusion (57 kJ/mol) and for convective mass transfer (78 kJ/mol). Thus this study showed the possibilities for designing efficient drying processes for the thistle flower used for milk-clotting in the manufacture of traditional cheeses.

Published: October 2019

Abstract Yacon syrup (YS) and cashew apple extract (CAE) are products with high concentrations of bioactive compounds such as fructooligosaccharides and carotenoids, which exhibit prebiotic and antioxidant properties. The objective of this work was to evaluate the impact of YS and CAE on the chemical, physical, physicochemical and sensory properties when these products were incorporated into natural yoghurt. Initially, the YS and CAE were characterized by chemical, physical and physicochemical analyses. The bioactive compounds, such as carotenoids, fructooligosaccharides and phenolic compounds, and the antioxidant activity were also determined. After characterization, natural yoghurt was supplemented with YS and CAE in different concentrations as follows: formulation A (non-supplemented yoghurt, as the control), formulation B (yoghurt with the addition of 20% of YS), formulation C (yoghurt with the addition of 20% of YS and 10% of CAE) and formulation D (yoghurt with the addition of 20% of YS and 20% of CAE). The formulations were evaluated for their sensory acceptance (overall acceptance, texture and appearance) and purchase intent, and were then characterized by chemical, physicochemical and physical analyses. The results indicated that the YS and CAE presented high concentrations of bioactive compounds, such as fructooligosaccharides and carotenoids, respectively. In addition, when the yoghurt was supplemented with these products, this induced changes in the chemical, physicochemical and physical properties of the yoghurt. In the sensory analysis, all the formulations presented good acceptance. The results indicated that yoghurt could be considered as an interesting vehicle for YS and CAE, products with high levels of bioactive compounds that may exert beneficial effects on human health.

Published: October 2019

Abstract Aims: To evaluate the nutritional status, resting energy expenditure, caloric and protein intake, and evolution of biochemical parameters in three stages of chronic kidney disease: pre-dialytic, at the beginning of the dialysis treatment, and 30 days after starting treatment. Methods: The chi-square and Student’s t tests were used to compare the variables, and analysis of repeated measurements was used to compare the data obtained in the three moments evaluated. The results were discussed at the 5% level of significance. Results: We evaluated 35 patients, 60% female and 60% with diabetes mellitus. There was a decrease in midarm circumference and serum albumin. Inflammatory state and caloric and protein intake increased. There was no significant difference in resting energy expenditure in the three moments. The serum urea and serum albumin, handgrip strength, and protein consumption after 30 days from the start of dialysis were greater in the peritoneal dialysis patients, when compared to the hemodialysis population. Conclusion: there was a decrease in midarm circumference and serum albumin and an increase in protein intake after dialysis. The peritoneal dialysis patients had higher muscle strength, even with lower protein intake. Resting energy expenditure was not different between dialysis methods and the moments evaluated.
Effectiveness, safety and cost reduction of long-term tunneled central venous catheter insertion in outpatients performed by an interventional nephrologist
Authors: Quintiliano Artur , Praxedes Marcel Rodrigues Gurgel
Published: October 2019

Abstract Introduction: Invasive procedures performed by trained nephrologists can reduce delays in making a definitive vascular access, complications, number of procedures on the same patient, and costs for the Public Health System. Objective: to demonstrate that a long-term tunneled central venous catheter (LTCVC) implanted by a nephrologist is safe, effective, and associated with excellent results. Methods: A retrospective study analyzed 149 consecutively performed temporary-to-long-term tunneled central venous catheter conversions in the operating room (OR) from a dialysis facility from March 2014 to September 2017. The data collected consisted of the total procedures performed, demographic characteristics of the study population, rates of success, aborted procedure, failure, complications, and catheter survival, and costs. Results: the main causes of end stage renal disease (ESRD) were systemic arterial hypertension and diabetes mellitus, 37.9% each. Patients had a high number of previous arteriovenous fistula (1.72 ± 0.84) and temporary catheter (2.87 ± 1.9) attempts until a definitive vascular access was achieved, while the preferred vascular site was right internal jugular vein (80%). Success, abortion, and failure rates were 93.3%, 2.7% and 4%, respectively, with only 5.36% of complications (minors). Overall LTCVC survival rates over 1, 3, 6, and 12 months were 93.38, 71.81, 54.36, and 30.2%, respectively, with a mean of 298 ± 280 days (median 198 days). The procedure cost was around 496 dollars. Catheter dysfunction was the main reason for catheter removal (34%). Conclusion: Our analysis shows that placement of LTCVC by a nephrologist in an OR of a dialysis center is effective, safe, and results in substantial cost savings.
Fluid and hemodynamic management in hemodialysis patients: challenges and opportunities
Authors: Canaud Bernard , Chazot Charles , Koomans Jeroen , Collins Allan
Published: October 2019

Abstract Fluid volume and hemodynamic management in hemodialysis patients is an essential component of dialysis adequacy. Restoring salt and water homeostasis in hemodialysis patients has been a permanent quest by nephrologists summarized by the ‘dry weight’ probing approach. Although this clinical approach has been associated with benefits on cardiovascular outcome, it is now challenged by recent studies showing that intensity or aggressiveness to remove fluid during intermittent dialysis is associated with cardiovascular stress and potential organ damage. A more precise approach is required to improve cardiovascular outcome in this high-risk population. Fluid status assessment and monitoring rely on four components: clinical assessment, non-invasive instrumental tools (e.g., US, bioimpedance, blood volume monitoring), cardiac biomarkers (e.g. natriuretic peptides), and algorithm and sodium modeling to estimate mass transfer. Optimal management of fluid and sodium imbalance in dialysis patients consist in adjusting salt and fluid removal by dialysis (ultrafiltration, dialysate sodium) and by restricting salt intake and fluid gain between dialysis sessions. Modern technology using biosensors and feedback control tools embarked on dialysis machine, with sophisticated analytics will provide direct handling of sodium and water in a more precise and personalized way. It is envisaged in the near future that these tools will support physician decision making with high potential of improving cardiovascular outcome.
Tratamento Diretamente Observado da tuberculose: análise crítica da descentralização
Authors: Junges José Roque , Burille Andréia , Tedesco Jiocasta
Published: October 2019

O presente artigo discute a descentralização do Tratamento Diretamente Observado (TDO) da tuberculose (TB) em um município da região metropolitana de Porto Alegre, RS. Após a implementação da estratégia, as taxas de abandono do tratamento diminuíram, mas o município não alcançou a meta preconizada pela Organização Mundial de Saúde (OMS). Trata-se de uma pesquisa qualitativa que entrevistou profissionais da atenção primária e da vigilância em saúde. Os resultados apontaram que a descentralização apenas do procedimento pode significar somente o acréscimo de mais uma tarefa para a atenção primária e alimentar a compreensão de uma responsabilidade parcial, não coerente com esse nível de atenção. Como possibilidade para diminuir o abandono, sugere-se a descentralização completa do cuidado para atenção primária e a constituição de apoio matricial que envolva profissionais especializados e o núcleo de vigilância.

Published: October 2019

Resumen Indagar sobre experiencias de formación investigativa desde las apreciaciones de docentes en formación a nivel de pedagogía infantil evidencia un problema fundamental: su caracterización, interpretación y actualización desde la tensión que supone su formación académica y su ejercicio profesional. En tal sentido, el artículo analiza las características subyacentes a este proceso desde las estudiantes del curso Opción de grado (periodos académicos 2018-1, 2018-2 y 2018-3) de la Licenciatura en Pedagogía Infantil (Distancia), carrera ofertada por la Corporación Universitaria Minuto de Dios – UNIMINUTO (Colombia) en la Vicerrectoría Regional Bogotá Sur. Para ello, el texto señala el desarrollo de una etnografía educativa por la cual se observaron (diarios de campo), indagaron (cuestionario virtual) y analizaron conceptualmente (resúmenes de análisis documental) las experiencias formativas en investigación de las estudiantes. Los resultados alcanzados, si bien afirman la relevancia del proceso para el desarrollo de sus prácticas pedagógicas, explicitan también una problemática en cuanto a su carácter procedimental, el cual les impide problematizar aquellas prácticas como escenario investigativo. Así pues, el texto infiere la necesidad de visibilizar los saberes adquiridos por las estudiantes en su experiencia formativa y profesional; apropiar como criterio pedagógico el acervo investigativo del docente y su capacidad para desarrollar procesos pedagógicos desde metodologías de formación y mediaciones virtuales diversas; y delimitar marcos conceptuales que permitan actualizar el proceso formativo en investigación con el interés de desplegar capacidades para apropiar los saberes emergentes de las prácticas pedagógicas como realidad investigativa para las docentes en formación.

Published: October 2019

Physical modelling studies of submarine landslides in a 5° slope were conducted to assess the occurrence of hydroplaning and turbidity currents. The centrifuge modelling did not aim to simulate the complete mudflow mechanism, but rather focused on assessing the hydroplaning and the turbidity current conditions. Four tests were performed using kaolin clay in a drum centrifuge (N = 40). The initial water content of the slurry and the pressure associated with the release of the mixture inside the centrifuge were varied during the tests in order to simulate different flow rates. The test results were evaluated by means of pore pressure and total stress measurements at the mudflow−slope interface in order to identify the flow conditions in which hydroplaning takes place. Froude and Reynolds numbers were also used to identify the turbidity current and hydroplaning phenomena. The particle image velocimetry technique was used to obtain the velocity field in order to complement the analysis.

THERMODYNAMIC INTERACTION COEFFICIENTS IN LOW-CONCENTRATED LIQUID BINARY ALLOYS
Authors: Bol’shov L. A. , Korneichuk S. K.
Published: October 2019

The article considers basic expansion of thermodynamics and thermodynamic interaction coefficients of the first, second and third orders of low-concentrated binary alloys. The values of interaction coefficients of the first and second orders in 37 such systems were estimated according to experimental thermodynamic data on the concentration dependence of excess chemical potential of an impurity in liquid alloys of binary systems. Estimates were obtained by the numerical differentiation method. This method is based on Newton first interpolation formula. Calculation formulas for the corresponding estimates are given. A simple theory is proposed that relates the thermodynamic interaction coefficient of the second order with the first-order one in the liquid alloy of certain system. The theory is based on the lattice model of a solution and the principles of statistical mechanics. The FCC lattice is adopted as a model lattice. The model of pair interaction between metal atoms in the alloy was used. The radius of this interaction corresponds to radius of the nearest atomic shell. Using the proposed theory, thermodynamic interaction coefficients of the second-order for all 37 systems considered in this work, as well as the values of the third order interaction coefficients for 23 systems out of 37 mentioned above, were calculated. For these 23 systems, theoretical estimates of the second-order interaction coefficients are in agreement with experimental ones both by sign and by order of magnitude. This circumstance can be considered as evidence of applicability of the numerical differentiation method for estimation of thermodynamic interaction coefficients of the first and second orders in liquid binary alloys. The accuracy of estimating the values of the third derivative by numerical differentiation is insufficient. That makes it impossible to compare the calculated values of the interaction coefficients of the third order with the experimental ones, obtained by this method. It can be assumed that the theoretical calculations just give an idea of the magnitudes’ order of these coefficients.
CALCULATION OF THE THERMODYNAMIC CHARACTERISTICS OF Fe – P SYSTEM BY METHOD OF MOLECULAR DYNAMICS

Published: October 2019

The problem of dephosphorization of iron-carbon alloys is relevant for the metallurgical industry, since a high concentration of phosphorus contributes to the appearance of a number of extremely undesirable phenomena. A lot of experimental work has been devoted to solving this problem, but it has still not been completely possible to cope with it. Any field experiments aimed at studying the process of phosphorus removal, require considerable material and time costs, but at the same time do not guarantee getting the desired result. Therefore, to search for new approaches to solving this problem, it is much more rational to use numerical simulation methods involving the computational capabilities of modern computers. At present, computer experiments are the same recognized research method as theoretical research and real experiment. To study the behavior of phosphorus atoms in iron using a numerical experiment, it is necessary to build a computational model and test it by calculating various characteristics whose values are known in advance. In this paper, the method of molecular dynamics was chosen as the method of computer simulation. Using this method, one can conduct experiments with given atomic velocities and describe dynamics of the studied processes. To describe the interparticle interaction, we used the potential calculated in the framework of the immersed atom method. The study was conducted on a computational cell simulating α-iron crystal with phosphorus substitution atoms. The constructed model demonstrated satisfactory results when calculating the known characteristics of the simulated system. Dependences of changes in such characteristics as temperature coefficient of linear expansion, melting point, latent heat of melting and heat capacity on the concentration of phosphorus atoms, as well as in some cases on magnitude of the applied external pressure were established. Calculations showed that, for example, the phosphorus concentration of 0.5 % leads to an increase in the average thermal coefficient of linear expansion by 9 %, a decrease in temperature and latent heat of fusion by 5 % and a heat capacity by 7 %.
FATIGUE PROCESS OF AUTOMOBILE MATERIALS

Published: October 2019

During operation, the structural elements of cars are exposed to temperatures and vibrations. Overwhelming majority of the destruction of metal structures is caused by their fatigue. It causes economic losses and often human casualties from accidents. Therefore, the task of ensuring the operability of parts and components of automobiles is one of the most relevant in the modern automotive industry. So it is necessary to know the patterns of behavior of metallic materials, obtained by different technologies, when they are exposed to vibration. Destruction of the metal structure directly affects the behavior of the samples deflection, reflecting the competition of two mutually oppositephenomena – hardening and softening. It directly influences structural damageability of the metal. The article is devoted to the study of kinetics of fatigue failure of automotive materials using the calibration of structural damage to their surface with behavior of the curves of changes in current deflection under alternating loading. The paper considers automotive materials (steel grades 20KhI3, 14Kh17N2, 35KhGSА) and model metals and alloys (Copper M1, Brass L63T, aluminum alloy V95pchT2) in different structural state under cyclic loading for low, room and high temperatures with fixation of the sample deflection and structural damage corresponding to it. It is possible to study kinetics of fatigue destruction of the sample material by the deflection curves, which is an integral characteristic of destructive processes occurring under alternating loading. Using these processes, one can track the stages of damage during fatigue of metallic materials – damage to the structure at the initial stage, moment of the macroscopic crack appearance, its subsequent advancement up to complete separation of the structural material. It is probable to identify ratio of the period duration before the appearance of a fatigue crack and its subsequent growth, as well as to determine the average rate at which the fatigue crack moves through the body of the metal sample. It is important that it is also possible to estimate the kinetics of materials destruction under the conditions when direct study of the structural state of the sample surface is impossible, for example, in conditions of cryogenic and high temperatures, and also, for example, in the presence of corrosive media. In combination with fractographic and metallographic analysis of the fatigue process, the deflection curves allow, based on the evaluation of the stages of materials destruction, to carry out selection of the latter for the structural elements of a car taking into account its operating conditions and optimizing the technology of parts manufacturing to increase serviceability and maintainability.

Published: October 2019

The system of legal regulation of the issues of granting governmental and municipal services in present-day Russia is being formed already after determining the main aspects of the public authorities functioning, which predetermines the peculiarities of the legal norms installing into the single composition of the single legal space. The article examines the history of adoption of the Federal Law No. 210-FZ of July 27, 2010 «On Organizing Provision of Governmental and Municipal Services» on the basis of the analyzing the texts of the draft law in three readings, the comments and the amendments to the draft law, as well as other sources. The purpose of analyzing the adoption history of the Federal Law No. 210-FZ, carried out in the article, is to identify the causes of arising the problems associated with its application in practice. The article examines the evolution of the name of the bill, later codified as Federal Law No. 210-FZ, as well as the subject of its legal regulation. The author identifies the causes and consequences of exclusion of a number of definitions from the draft law. The analysis of the provisions of the law in question shows the need for a legislative definition of the concept of «governmental (municipal) function».
Consumers’ Acceptance of Internet of Things Technology
Authors: BUMİN DOYDUK Hande Begüm , BAYARÇELİK Ebru Beyza
Published: October 2019

Recent technological advancements entail immense changes and lead to a new era. One of the main change agents of this new era is internet of things technologies. The term “internet of things” (IoT) indicates objects having an identity and having ubiquitous connection with each other. Notwithstanding the novelty of the concept, it captured the interest of many scholars and practitioners. The subject area has not been analyzed profoundly from the consumers’ point of view. Whenever potential users face a new technology, they experience an acceptation process. In this study, how this new concept is perceived by the consumers is scrutinized. Consumer perspective of IoT is studied through Technology Acceptance Model (TAM). TAM introduced perceived ease of use and perceived usefulness, as signiﬁcant determinants for a potential user to have behavioral intention to use a new technology. Data were analyzed through Structural Equational Modeling (SEM).
La violencia Masculina en la Pareja como Proceso Relacional: Un Desafío de Superación Cultural
Authors: Bustamante Clarisa Martínez , Quintal López Rocío Ivonne , Amarís Macías María
Published: October 2019

The present essay tries to understand the dynamics of domestic violence from the three following angles: masculinity, identity and power relationships as socio-cultural expressions. The first two are approaches to masculinity as a culture construct, its relationship with the process of culture identities and the exercise of violence against the intimate partner as a mechanism of cohesion. The third angle is based upon Bourdieu’s (2000) concept of power and domination, in dialogue with Ramirez's explanatory proposal of power relationships (2005), to finally criticize the approach of the victim / aggressor dichotomy from changes within the gender relationships where the role of men and women take new nuances. From the analysis of these components we reflect on the phenomenon of intimate violence as part of a relational process within globalization's growth, in which both men and women are capable of transcending the “social destiny” by contributing to their generic practices new meanings for its overcoming.

Highlights of a Cursory Study of Behavior of Three Instrumented Buildings during the Mw 7.1 Anchorage, Alaska, Earthquake of 30 November 2018
Authors: Çelebi Mehmet
Published: October 2019

This is a cursory study of the recorded responses of three buildings instrumented by the U.S. Geological Survey (USGS) in Anchorage, Alaska, during the Mw 7.1 earthquake of 30 November 2018. The earthquake caused the strongest shaking in Anchorage since the well‐known 1964 Mw 9.2 Great Alaska earthquake. Since the 1964 event, several structures (buildings and bridges) in Anchorage have been instrumented by the USGS, and their responses have been recorded during multiple events. For each of the three buildings (the 14‐story Frontier Building, the 20‐story Atwood Building, and the 22‐story Hilton Hotel) studied herein, essential dynamic characteristics and significant behavioral aspects such as beating and torsional motions are identified. Recorded peak accelerations and displacements are provided, and average drift ratios are computed using the peak displacements at the roof levels with respect to the ground level. These average drift ratios imply that the motions are at levels expected not to cause damage to the buildings. Visualization videos of both the 14‐story Frontier and the 20‐story Atwood Buildings have been developed to display overall shaking of the buildings during the earthquake.
The Impact of USArray on Earthquake Monitoring in Alaska
Authors: Ruppert Natalia A. , West Michael E.
Published: October 2019

Seismic network coverage in Alaska has fundamentally changed with the presence of the USArray Transportable Array (TA) stations. These new stations provided an unprecedented opportunity to expand earthquake reporting in areas of Alaska that have not previously been instrumented. The Alaska Earthquake Center (AEC) has been incorporating all TA data into its standard earthquake analysis. The TA network is currently the second largest contributor of phase picks in the Alaska earthquake catalog, after the AK network operated by the AEC. Recent increases in reported earthquakes (about 45,000 in 2017 and 55,000 in 2018) are directly attributable to the additional TA stations, especially in the northern and western mainland Alaska. In some regions, the earthquake detection threshold decreased by as much as two units of magnitude. With the TA installation complete in 2017, the detection threshold over the entire mainland Alaska region is M∼1.5. The new stations have also led to a decrease in hypocentral location errors, which are now more uniform over the entire mainland Alaska region. The uniformity of the TA network made it possible, for the first time, to make quantitatively valid comparisons of microseismic activity in different parts of the state. Among other observations, this uniform coverage helped demonstrate that the quiescence that has long been inferred in the central and western Arctic Slope region appears to be real, and not just an artifact of network coverage. This combined network should, with time, provide vastly better data for seismic hazard assessments in an area of increasing national interest.
Türkiye Ekonomisinde Cari İşlemler Açığının Belirleyicileri: Dönemler Arası Yaklaşım
Authors: BENLİ Ali , TONUS Özgür
Published: October 2019

Bu çalışmanın temel amacı Türkiye ekonomisinde cari işlemler açığına neden olan temel makroekonomik, finansal ve yapısal faktörleri betimsel istatistikler ve ampirik analiz yardımıyla araştırmaktır. Türkiye’de özellikle 2001 krizi sonrasında genişleyen ve kalıcı hale gelen cari işlemler açığı konusundaki endişeler artmıştır. Çalışmada kullanılan ampirik model “dönemler arası” ve “esneklikler” yaklaşımlarının bir sentezi niteliğindedir. Cari işlemler dengesini ulusal gelir, bütçe dengesi, döviz kuru ve faiz oranlarının bir fonksiyonu olarak ele almaktadır. Model kısa ve uzun dönemlik analizlere olanak tanıyan ARDL yaklaşımı ile üç aylık frekanstaki veriler kullanılarak tahmin edilmiştir. Bulgulara göre bütçe dengesi, döviz kuru ve faiz oranı cari işlemler dengesi üzerinde uzun dönemde etkiliyken, kısa dönemde sadece GSYH ve bütçe dengesi etkilidir. Bütçe dengesi ile ilgili bulgular Ricardocu Denklik Hipotezinin Türkiye ekonomisinde geçerli olmadığını, İkiz Açık Hipotezinin ise geçerliliğini göstermektedir.
A Case Study on Incorporating Health and Equity into Urban Plans, Transportation, and Land Use Policies

Published: October 2019

In 2017, the Built Environment Program at the Larimer County Department of Health and Environment (Colorado, USA) collaborated with a partner municipal agency to create a health and equity index to be a component of a revitalized sidewalk prioritization model. The Health Equity Index uses indicators that are linked to the determinants of health to spatially understand factors that contribute to an individual or household’s likelihood of being more vulnerable. The data to create the Health Equity Index is publicly sourced at block group level from the United States Census American Community Survey 5-year estimates and at census tract level from the Center for Disease Control and Prevention’s 500 Cities dataset. The score is one of three factors used to determine sidewalk improvement priorities in the City. The new model mapped prioritization and created broader geographic distribution than what was previously used. The creation of the Health Equity Index was a valuable partnership that led to multiple outcomes outside of the sidewalk prioritization process. First, its creation has established a foundation for partnership between two sectors across different government agencies. Second, the Health and Equity Index has also been used as an assessment tool for the adopted City Plan, the guiding comprehensive plan for the municipal agency. Through this process, we have learned that elements of Health Impact Assessment can be a powerful tool for understanding the health impacts of a policy or process on community, as well as for building and developing trusted cross-sector relationships.
