Background

New technologies create possible new ways of action, interaction, and learning which is extremely relevant in the field of oral health education. There is a lack of protocol in using an immersive interactive ludic-educational interface to motivate oral hygiene practice in children by means of augmented reality.

Objective

This study aims to present a protocol on the development of a serious game to motivate oral hygiene practice in children.

Methods

A serious game will be designed by augmented reality techniques to improve toothbrushing effectiveness of children aged 6 to 10 years. The functional structure of this interface is activated by means of movements recognized by Kinect (Microsoft Corp). The toothbrushing technique will be available in the game, enabling the children to execute the movement in the virtual environment. By identifying errors, this game will be tailored to improve the oral health of children by correcting the technique and teaching the user the adequate toothbrushing method. A template analysis will be performed to identify barriers and facilitators in each scenario.

Results

After the implementation of the virtual interactive and immersive panels, enrollment will begin and evaluations will be made by means of questionnaires distributed to participants who interact with the game. Thus, an analysis of the product efficacy will be conducted. The expected outcome will be to obtain a digital instrument to motivate oral hygiene practice and enhance health awareness in children.

Conclusions

The serious game will support the prevention of oral diseases by sharing scientific research in the school environment and community.

Published: February 2019

BACKGROUND

Although infectious diseases are globally on the decline, they remain a major global public health problem. Among them, the hepatitis B virus (HBV) or hepatitis C virus (HCV) and HIV infection are of primary interest. Valid prevalence data on these infections are sparse in Greece, especially for vulnerable populations.

OBJECTIVE

This study aimed to present the design and methods of Hprolipsis, an integrated viral hepatitis and HIV screening program administered to adults (≥18 years) from the general, Greek Roma, and migrant populations. Its aims were to estimate the prevalence of HBV, HCV, and HIV; assess infectious disease knowledge level; design, implement, and assess population-specific awareness actions; and offer individual counseling and referral when indicated and HBV vaccination to susceptible Roma and migrants.

METHODS

Multistage, stratified, random sampling based on the 2011 Census was applied to select the general population sample, and nonprobability multistage quota sampling was used for Roma and migrant sample selection. Trained personnel made home (general population) or community (Roma and migrants) visits. Collected blood samples were tested for Hepatitis B surface Antigen, Hepatitis B core Antibody, Hepatitis B surface Antibody, Hepatitis C Antibody, and HIV 1,2 Antibody. The surveys were conducted during May 2013 and June 2016. To estimate an HCV prevalence of 1.5% with 0.3 precision, the required general population sample size was estimated to be 6000. As migrants constitute 10% of the whole Greek population, the migrant sample size was set to 600. A feasible sample size of 500 Greek Roma was set.

RESULTS

In total, 6006 individuals from the general population (response rate 72%), 534 Greek Roma, and 612 migrants were recruited. Blood test results are available for 4245 individuals from the general population, 523 Roma, and 537 migrants.

CONCLUSIONS

Hprolipsis is the first nationwide survey on HBV, HCV, and HIV. Its results will enhance our understanding of the health needs and disease burden of these diseases in the 3 studied populations. Its implementation provided useful recommendations for future studies, particularly in vulnerable populations.

Authors: Lindauer Allison , McKenzie Glenise , LaFazia David , McNeill Loriann , Mincks Kate , Spoden Natasha , Myers Marcella , Mattek Nora , Teri Linda L
Published: February 2019

BACKGROUND

Families living with Alzheimer disease and related dementias have more access to support thanks to the development of effective telehealth-based programs. However, as technological science grows, so does the risk that these technology-based interventions will diverge from foundational protocols, diluting their efficacy. Strategies that ensure programs are delivered as intended, with fidelity to guiding protocols, are needed across the intervention spectrum—from development to wide-scale implementation. Few papers address fidelity in their technology-based work. Here, we present our translated telehealth intervention, Tele-STAR, with our fidelity findings.

OBJECTIVE

This study aimed to assess the preliminary efficacy of Tele-STAR on reducing family caregiver burden and depression. Across the implementation phases, we assessed the fidelity of a caregiver education intervention, STAR-C, as it was translated into a telehealth option (Tele-STAR).

METHODS

A total of 13 family caregivers consented to participate in an 8-week, videoconference-based intervention (Tele-STAR). Tele-STAR efficacy in reducing the affective burden of caregiving was assessed using pre- and postintervention paired t tests. Content experts assessed program fidelity by reviewing and rating Tele-STAR materials for adherence to the original STAR-C protocol. These experts assessed treatment fidelity by viewing videos of the intervention and rating adherence on a checklist.

RESULTS

Tele-STAR reduced caregiver burden and retained good program and treatment fidelity to STAR-C.

CONCLUSIONS

We found Tele-STAR reduced caregiver burden and had good fidelity to the original protocol. Assessing fidelity is a complex process that requires incorporation of these procedures early in the research process. The technology used in this study facilitated the accrual of informative data about the fidelity of our translated intervention, Tele-STAR.
Predicting Dropouts From an Electronic Health Platform for Lifestyle Interventions: Analysis of Methods and Predictors (Preprint)
Authors: Pedersen Daniel Hansen , Mansourvar Marjan , Sortsø Camilla , Schmidt Thomas
Published: February 2019

BACKGROUND

The increasing prevalence and economic impact of chronic diseases challenge health care systems globally. Digital solutions can potentially improve efficiency and quality of care, but these initiatives struggle with nonusage attrition. Machine learning methods have been proven to predict dropouts in other settings but lack implementation in health care.

OBJECTIVE

This study aimed to gain insight into the causes of attrition for patients in an electronic health (eHealth) intervention for chronic lifestyle diseases and evaluate if attrition can be predicted and consequently prevented. We aimed to build predictive models that can identify patients in a digital lifestyle intervention at high risk of dropout by analyzing several predictor variables applied in different models and to further assess the possibilities and impact of implementing such models into an eHealth platform.

METHODS

Data from 2684 patients using an eHealth platform were iteratively analyzed using logistic regression, decision trees, and random forest models. The dataset was split into a 79.99% (2147/2684) training and cross-validation set and a 20.0% (537/2684) holdout test set. Trends in activity patterns were analyzed to assess engagement over time. Development and implementation were performed iteratively with health coaches.

RESULTS

Patients in the test dataset were classified as dropouts with an 89% precision using a random forest model and 11 predictor variables. The most significant predictors were the provider of the intervention, 2 weeks inactivity, and the number of advices received from the health coach. Engagement in the platform dropped significantly leading up to the time of dropout.

CONCLUSIONS

Dropouts from eHealth lifestyle interventions can be predicted using various data mining methods. This can support health coaches in preventing attrition by receiving proactive warnings. The best performing predictive model was found to be the random forest.
Exploring the Potential for Use of Virtual Reality Technology in the Treatment of Severe Mental Illness Among Adults in Mid-Norway: Collaborative Research Between Clinicians and Researchers (Preprint)
Authors: Ose Solveig Osborg , Færevik Hilde , Kaasbøll Jannike , Lindgren Martin , Thaulow Kristin , Antonsen Stig , Burkeland Olav
Published: February 2019

BACKGROUND

Virtual reality (VR) technology is not currently used in the treatment of severe mental health illness in Norway.

OBJECTIVE

We aimed to explore the potential of VR as a treatment for severe mental health illness in Norway, through collaborative research between clinicians and researchers.

METHODS

A collaborative research team was established, comprising researchers, the manager at a district psychiatric center, and the manager of the local municipal mental health service. An all-day workshop with eight clinicians—four from specialist mental health services and four from municipal mental health services—was conducted. The clinicians watched three different VR movies and after each one, they answered predefined questions designed to reflect their immediate thoughts about VR’s potential use in clinical practice. At the end of the workshop, two focus group interviews, each with four clinicians from each service level, were conducted.

RESULTS

VR technology in specialist services might be a new tool for the treatment of severe mental health illness. In municipal mental health services, VR might particularly be useful in systematic social training that would otherwise take a very long time to complete.

CONCLUSIONS

We found substantial potential for the use of VR in the treatment of severe mental health illness in specialist and municipal mental health services. One of the uses of VR technology with the greatest potential was helping individuals who had isolated themselves and needed training in social skills and everyday activity to enable them to have more active social lives. VR could also be used to simulate severe mental illness to provide a better understanding of how the person with severe mental illness experiences their situation.
Recruiting Student Health Coaches to Improve Digital Blood Pressure Management: Randomized Controlled Pilot Study (Preprint)
Authors: Vasti Elena , Pletcher Mark J
Published: February 2019

BACKGROUND

Hypertension is a significant problem in the United States, affecting 1 in 3 adults aged above 18 years and is associated with a higher risk for cardiovascular disease and stroke. The prevalence of hypertension has increased in medically underserved areas (MUAs). Mobile health technologies, such as digital self-monitoring devices, have been shown to improve the management of chronic health conditions. However, patients from MUAs have reduced access to these devices because of limited resources and low health literacy. Health coaches and peer training programs are a potentially cost-effective solution for the shortage of physicians available to manage hypertension in MUAs. Activating young people as student health coaches (SHCs) is a promising strategy to improve community health.

OBJECTIVE

This pilot study aims to assess (1) the feasibility of training high school students as health technology coaches in MUAs and (2) whether the addition of SHCs to digital home monitoring improves the frequency of self-monitoring and overall blood pressure (BP) control.

METHODS

In total, 15 high school students completed 3-day health coach training. Patients who had a documented diagnosis of hypertension were randomly assigned to 1 of the 3 intervention arms. The QardioArm alone (Q) group was provided a QardioArm cuff only for convenience. The SHC alone (S) group was instructed to meet with a health coach for 30 min once a week for 5 weeks to create action plans for reducing BP. The student+QardioArm (S+Q) group received both interventions.

RESULTS

Participants (n=27) were randomly assigned to 3 groups in a ratio of 9:9:9. All 15 students completed training, of which 40% (6/15) of students completed all the 5 meetings with their assigned patient. Barriers to feasibility included transportation and patient response drop-off at the end of the study. Overall, 92% (11/12) of the students rated their experience as very good or higher and 69% (9/13) reported that this experience made them more likely to go into the medical field. There was a statistically significant difference in the frequency of cuff use (S+Q vs Q groups: 37 vs 17; P<.001). Participants in the S+Q group reported better BP control after the intervention compared with the other groups. The average BP at the end of the intervention was 145/84 (SD 9/18) mm Hg, 150/85 (SD 18/12) mm Hg, and 128/69 (SD 20/14) mm Hg in the Q, S, and S+Q groups, respectively.

CONCLUSIONS

This pilot study demonstrates the feasibility of pairing technology with young student coaches, although challenges existed. The S+Q group used their cuff more than the Q group. Patients were more engaged in the S+Q group, reporting higher satisfaction with their SHC and better control of their BP.
Mitos y recorridos divinos en la veintena de Panquetzaliztli
Authors: Mazzetto Elena
Published: February 2019

Resumen: En este artículo se estudia el recorrido ceremonial llamado Ipaina Huitzilopochtli que se llevaba a cabo en la veintena de Panquetzaliztli, la fiesta del dios tutelar mexica en el ciclo del calendario solar. Mediante un análisis comparativo tanto de distintas crónicas coloniales en náhuatl y en español, como de las contribuciones modernas, se reflexionan aspectos olvidados por los investigadores. Asimismo, se analizan los distintos espacios por donde los protagonistas transitaban de un lugar a otro, y se examinan las personalidades sobrenaturales involucradas en el recorrido, en relación con la recreación anual del mito del nacimiento de Huitzilopochtli. Los resultados de la investigación sobre estos “múltiples” recorridos apuntan hacia la necesidad del estudio multifacético de la dimensión social y política del Valle de México, y del contexto de creación de las crónicas novohispanas, para el logro de una buena comprensión de acontecimientos religiosos determinados.Summary:This article covers the study of the ceremonial procession known as Ipaina Huitzilopochtli, which took place in the twenty-day cycle of Panquetzaliztli, the festival of the guardian Mexica god in the solar calendar cycle. A comparative analysis, both of different colonial chronicles in Náhuatl and Spanish, and modern contributions, reflects on certain aspects overlooked by researchers. In addition, the different routes along which the main players traveled from one place to another are analyzed and the supernatural characters involved in the journey are examined in relation to the annual recreation of the myth of the birth of Huitzilopochtli. The results of the research into these “multiple” journeys point to the need for a multi-faceted study of the social and political dimension of the Valley of Mexico and of the context of the creation of the Colonial chronicles in order to gain a better understanding of specific religious events.Résumé : Cet article étudie le parcours cérémoniel connu sous le nom d’Ipaina Huitzilopochtli, qui était effectué au cours de la vingtaine de Panquetzaliztli, la fête du dieu tutélaire mexica dans le cycle du calendrier solaire.

La fiesta de Atlcahualo y el paisaje ritual de la Cuenca de México
Authors: Broda Johanna
Published: February 2019

Resumen: Este artículo inicia con el recuerdo de Michel Graulich, con quien compartí el interés por estudiar las fiestas del calendario mexica. En esta aportación se retoman los resultados de numerosas investigaciones que he realizado sobre las fiestas mexicas de los dioses de la lluvia, y las fuentes del siglo XVI que proporcionan información detallada acerca de la realización de ritos en la geografía de la Cuenca. Uno de los aspectos más interesantes de éstos eran los sacrificios de niños que se efectuaban en la estación seca en petición de lluvias. Mediante recorridos de campo en la Cuenca, se registraron los lugares concretos donde estos sacrificios se llevaban a cabo. Se descubre así que estos ritos conformaban un cosmograma de los rumbos del universo y estaban ligados al registro calendárico y la observación astronómica; es decir, estaban basados en las condiciones geográficas y climáticas de la Cuenca en la época mexica.Summary:This article begins by remembering Michel Graulich, with whom I shared the interest in studying the festivals of the Mexica calendar. This contribution picks up on the results of numerous research studies conducted on Mexica festivals of the rain gods and the sources from the sixteenth century that provide detailed information on the rituals held in the Valley area. One of the most interesting aspects of these was the sacrifice of children in the dry season to summon the rains. The exact sites where these sacrifices took place were recorded by making field trips in the Valley. Here, it was discovered that these rituals formed a cosmogram of the bearings of the universe and were linked to calendar registrations and astronomical observations; i.e.; they were based on the geographical and climatic conditions in the Valley during the Mexica era.Résumé : Cet article commence par saluer la mémoire de Michel Graulich, qui partageait mon intérêt pour l’étude des fêtes du calendrier mexica. J’y reprends les résultats de nombreuses recherches que j’ai menées sur les fêtes mexicas des dieux de la pluie, ainsi que les sources du xvie siècle qui fournissent des informations détaillées sur la réalisation de rites dans la géographie du bassin de Mexico. L’un des aspects les plus intéressants de ces rites était le sacrifice d’enfants effectué pendant la saison sèche pour faire venir la pluie. Des visites de terrain nous ont permis de localiser les endroits récis où étaient réalisés ces sacrifices. On a ainsi découvert que les emplacements de ces rites composaient un cosmogramme représentant les directions de l’univers, et qu’ils étaient liés au système calendaire et à l’observation astronomique, ainsi qu’au contexte géographique et aux conditions climatiques du bassin de Mexico à l’époque des Mexicas.

Authors: Ramagopalan Sreeram V , Graham Sophie , Carroll Robert , Raluy-Callado Mireia , Nordstrom Beth L , Donaldson Robert , Colby Chris , Mehmud Faisal , Alikhan Raza
Published: February 2019

Aim:
Nonvalvular atrial fibrillation (NVAF) requires long-term anticoagulation treatment, which may necessitate frequent primary care visits.
Materials & methods:
NVAF patients initiating warfarin or apixaban in 2012–2017 were identified from linked primary (Clinical Practice Research Datalink) and secondary care (Hospital Episode Statistics) data. A propensity score matched Cox regression model compared discontinuation risk. Primary care visits were compared via negative binomial regression.
Results:
A total of 2695 apixaban users were matched to warfarin patients. Discontinuation risk was lower with apixaban than warfarin (hazard ratio: 0.40; 95% CI: 0.35–0.46). Apixaban patients averaged 12.2 annual primary care visits, versus 17.1 for warfarin users (p < 0.001).
Conclusion:
Apixaban was associated with reduced rates of discontinuation and primary care visits compared with warfarin.
La Calidad de la Educación Básica en el Estado de Yucatán: Vista a través de las pruebas nacionales
Authors: Martínez Guzman Elvira , Lugo Lugo Felipe de la Cruz
Published: February 2019

Se realizó un estudio de corte cuantitativo, descriptivo y comparativo a lo largo del tiempo de cada prueba nacional administrada en Yucatán:
EXCALE, ENLACE, IDANIS, OCI y EXANI I .
La muestra proviene de bases de datos de cada prueba, con sujetos en edad escolar de tercero de primaria hasta tercero de secundaria.
El objetivo fue explicar el mejoramiento del logro educativo a través de resultados históricos en las pruebas nacionales de gran escala. Una
generación de EXCALE presentó incremento en el nivel Medio, en español; en cambio ENLACE aumentó los porcentajes de estudiantes en los
niveles Bueno y Excelente en español y matemáticas. Sin embargo un porcentaje importante de estudiantes históricamente estuvo en los niveles
no deseados en ambas pruebas.
No es suficiente difundir resultados; se rquiere de la participación de los involucrados en el análisis e interpretación y hacer uso adecuado de ello,
en aras de propiciar una mejora en las distintas esferas de la educación (Ruiz & Prado, 2018; Muskin, 2015).
El concepto de Calidad Educativa es complejo y multifactorial por tanto se sugiere su revisión en el Modelo de gestión regional de Yucatán. © 2017

Ansiedad ante la cirugía en pacientes oncológicos: Revisión de su evaluación, factores de riesgo e intervención psicológica.
Authors: Rivera-Fong Liliana , Rojas Castillo Edith , Gálvez-Hernández Lizette , Méndez-Meneses Karla Janeth , Aguilar-Ponce José Luis , Galindo Vázquez Oscar , Riveros-Rosas Angélica
Published: February 2019

El cáncer es una de las principales causas de morbilidad y mortalidad mundial, y frecuentemente el tratamiento requerido es multimodal, incluyendo
una o más cirugías con fines diagnósticos, curativos, preventivos o de paliación. Sin embargo, el procedimiento quirúrgico se ha asociado
al desarrollo de reacciones emocionales, como la ansiedad. La presente revisión de literatura reporta la prevalencia de ansiedad asociada a una
cirugía, los factores de riesgo para desarrollarla, su impacto en la evolución del paciente, algunas escalas disponibles para su evaluación y la eficacia
de algunas intervenciones psicológicas para el manejo de dicha sintomatología. Se ha documentado que el 9% de los pacientes oncológicos
que serán sometidos a una cirugía presentarán ansiedad por el proceso, la cual puede ser evaluada mediante instrumentos especializados para
dichos fines. La incidencia e intensidad de la ansiedad asociada a la cirugía está moderada por factores propios de la cirugía como su extensión, objetivo, consecuencias; y, por factores individuales como antecedentes psicológicos y apoyo social. La ansiedad relacionada con la cirugía se asocia con dificultades en la recuperación al procedimiento quirúrgico, por lo que se recomienda el abordaje psicológico mediante intervenciones breves al momento de la anestesia o cirugía que han mostrado mayor efectividad en el control inmediato y a corto plazo de la sintomatología. De esta forma la atención del paciente oncológico es un compromiso multidisciplinario en el que la evaluación y abordaje psicológico en momentos clave, como someterlo a un procedimiento quirúrgico, impacta directamente en su evolución, bienestar y calidad de vida. © 2017 Universidad Nacional Autónoma de México, Asociación Mexicana de Comportamiento y Salud.

Comparación de maneras sustitutivas y presustitutivas de trabajar textos con alumnos de primaria.
Authors: Rocha Leyva Héctor , Mares Cárdenas María Guadalupe , Rivas García Olga
Published: February 2019

Se analizó el efecto de dos maneras de propiciar interacciones con textos sobre la forma de interactuar con un texto diferente. En una de ellas se
formularon preguntas que demandan inferencias y la vinculación del tema con las experiencias del alumno (niveles sustitutivos), en la otra se incorporaron
también preguntas de selección de partes de un texto o de imágenes (niveles presustitutivos). Participaron 75 alumnos de segundo de
primaria inscritos en tres grupos de una escuela pública de México. De manera aleatoria se asignaron los grupos a tres condiciones: Experimental
1 (GE1), Experimental 2 (GE2) y Control (GC). Fase 1, se pidió que los alumnos leyeran un texto y contestaran preguntas y ejercicios ubicados
en diferentes niveles de interacción. Fase 2, el GE1 recibió un entrenamiento en donde durante la lectura se le presentaban preguntas sustitutivas, al GE2 se le presentaban preguntas sustitutivas y presustitutivas, y el GC continuó con la instrucción organizada por su maestra. Fase 3, se procedió de la misma manera que en la fase 1. Se encontraron diferencias significativas entre el grupo control y los experimentales después del entrenamiento, así como entre el GE1 y GE2 en el nivel sustitutivo referencial a favor del GE1. Se discuten las implicaciones para la práctica educativa en diversos niveles de estudio y las implicaciones conceptuales. © 2017 Universidad Nacional Autónoma de México, Asociación Mexicana de Comportamiento y Salud.

Published: February 2019

El trastorno por estrés agudo se caracteriza por sintomatología asociada al trastorno por estrés postraumático durante las primeras
cuatro semanas posteriores al trauma. Existen distintas limitaciones en la definición del constructo y su evaluación. El propósito
del estudio fue validar la Escala de Trastorno por Estrés Agudo en población mexicana mediante análisis factoriales. Se contó con
204 participantes de entre 18 y 59 años de edad. El análisis factorial exploratorio arrojó tres factores donde se agrupan: síntomas de
reexperimentación y activación, síntomas de evitación y síntomas disociativos, con una varianza explicada acumulada de 67.90%,
así como un Alpha de Cronbach .96 para la escala global, y .94, .91 y .89 para cada factor; por último, el análisis factorial confirmatorio
muestra un ajuste adecuado del modelo. Se concluye que la escala es válida y confiable en población mexicana, donde se
sugiere realizar análisis factoriales en distintas poblaciones para una mayor definición. © 2017 Universidad Nacional Autónoma de

Coaching as a Knowledge Mobilization Strategy: Coaches' Centrality in a Provincial Research Brokering Network
Authors: Rodway Joelle
Published: February 2019

Ontario’s Child and Youth Mental Health (CYMH) program is a provinciallysponsored  initiative that aims to build school district capacity for developing research-informed school mental health policies. This article reports findings from a mixed-methods study that employs social network theory and analysis tools to explore the centrality of CYMH coaches within this research brokering network. Overall, CYMH coaches are central within these social networks, although the patterns of interaction differ from the program’s original design, with some coaches being more central than others. While formal CYMH professional development events appear to be the most direct approach to connecting research, policy, and practice, informal social networks provide the support necessary to make sense of research-based materials for use in local policymaking.
Good Governance and Canadian universities: Fiduciary duties of university governing boards and their implications for shared collegial governance.
Authors: Shanahan Theresa Gemma
Published: February 2019

Using a legal framework, doctrinal analysis, critical legal analysis, and fundamental legal research and drawing upon legislation, case law, judicial, and scholarly commentary, this article defines the fiduciary duties of Canadian university governing boards given the unique features of the university as a legal entity. Thelegal  analysis considers the Canadian university as a corporation, distinguishing itfrom other types of corporations, identifying the charitable, not-for-profit, public/private dimensions of universities in Canada, and significantly, considering the judicially recognized “community of scholars” and collegial features of universities. The article argues that all of these features shape the fiduciary duties of governing boards and have implications for shared collegial governance in Canadian universities.
Evolución normativa e institucional de la Acuacultura en México.
Authors: Cuéllar Lugo Martha B. , Asiain Hoyos Alberto , Juárez Sánchez José Pedro , Reta Mendiola Juan L. , Gallardo López Felipe
Published: February 2019

A nivel mundial, la acuacultura ha tenido un crecimiento continuo durante los últimos 40 años, siendo una de las ramas del sector primario con mayor tasa de crecimiento sostenido anual. Paradójicamente, a pesar de que en México existen las condiciones ambientales, económicas y sociales para mantener o superar las tendencias internacionales, cifras oficiales muestran un crecimiento limitado. En este trabajo se plantea como hipótesis que la inestabilidad normativa e institucional, así como la poca continuidad y seguimiento en las políticas enfocadas a la acuacultura, inhiben el crecimiento de este sector productivo. El objetivo fue analizar la evolución normativa e institucional de la acuacultura en México, aplicando el método de la Ciencia Jurídica; se puntualizan de manera cronológica las decisiones presidenciales que determinaron las instituciones, organismos y dependencias que se encargaron de la organización, fomento y desarrollo del sector acuícola. Los resultados permitieron concluir que, debido a la multiplicidad de instituciones y normatividad en la materia, existe un deficiente desarrollo de este sector.
The Current State of Research Capacity in US Family Medicine Departments
Authors: Weidner Amanda , Peterson Lars E. , Mainous Arch G. , Datta Avisek , Ewigman Bernard
Published: February 2019

Background and Objectives: Capacity for conducting family medicine research has grown significantly since the specialty was founded. Many calls to increase this capacity have been published, but there has been no consistent, systematic, and longitudinal assessment. This survey was designed to gather baseline data with an easily replicable set of measures associated with research productivity that can guide and monitor the impact of efforts to build research capacity in US departments of family medicine (DFMs).
Methods: We surveyed family medicine department chairs regarding departmental research capacity using well-established empirical measures of capacity (trained research faculty, infrastructure, research leadership, and funding) and a self-assessment. We used bivariate analyses to assess correlation between the empirical measures and the self-assessed stage of research capacity.
Results: Self-assessed capacity was significantly associated with every empirical measure. High-capacity departments have more research-trained faculty, more faculty effort, utilize more research “laboratories,” have more faculty serving on federal peer-review panels, more faculty as principal investigators, devote more internal funding to research, and garner larger amounts of funding from more external funding sources than moderate or minimal-capacity departments.
Conclusions: US DFMs have made great strides over the past half century in building research capacity. However, much more capacity in family medicine and primary care research is needed to produce new knowledge necessary to improve the health and health care of the nation. Periodic measurement using the simple, replicable, and valid minimum measures of this study provides an opportunity to establish longitudinal tracking of change in research capacity in US DFMs.
A Systematic Approach to Understanding and Implementing Patient-Centered Care
Authors: Stollenwerk Diane , Kennedy Lauren Birchfield , Hughes Lauren S. , O'Connor Malachi
Published: February 2019

In 2014, Family Medicine for America’s Health (FMAHealth) began implementing a specialty-wide strategic plan. The FMAHealth Board of Directors created an Engagement Tactic Team and charged the team with two major objectives: (1) to engage patients as partners in transforming primary care, and (2) to strengthen working alliances with other primary care professions and key stakeholders to speak with a unified voice for primary care. The team’s first objective sought to engage patients as partners to achieve the triple aim. The second objective required the team to explore how best to collaborate with others to align on core values of high-functioning primary care.When it comes to realizing the promise of patient-centered care, aspirational strategic objectives are often easier to declare than to implement. As the team grappled with its charge, it discovered that the approach to achieving each objective became as important as the actions required to accomplish them. The team recognized the value of taking ample time to build an approach to delivering patient-centered care that could be sustained and scaled over time to achieve the two objectives.The team ultimately settled on three projects that leveraged collaborative partnerships with organizations inside and outside the specialty to better understand and advance patient-centered care at three levels: practice transformation, organizational governance, and policy making.

Background and Objectives: The Family Medicine for America’s Health Workforce and Education Team aims to increase the number of medical students choosing family medicine to address the projected primary care physician shortage. This aim can be achieved by developing a well-trained primary care workforce. Our student- and resident-led FMAHealth work group aimed to identify factors that influenced fourth-year medical students’ choice to become family physicians. The secondary objective compared such factors between the 10 medical schools with the highest percentage of students matching into family medicine and non-top 10 medical schools.
Methods: Fourth-year medical students nationwide participated in 90-minute virtual focus groups. Reviewers coded deidentified transcriptions and identified key themes and subthemes that were found to influence student choice.
Results: Fifty-five medical students participated in focus groups over a 2-year period. Three key themes were found to influence students: perspective, choice, and exposure. Subthemes included: (1) the importance of high-quality preceptors practicing full-scope family medicine, (2) the value of a rural experience, and (3) institutional support to pursue family medicine. Physician compensation and loan repayment concerns were not major factors influencing student choice.
Conclusions: Many factors influence student choice of family medicine including preceptors, clinical exposures, and institutional support. These factors varied by institution and many were found to be different between top 10 and non-top 10 schools. Addressing these factors will help increase students’ choice of family medicine and reduce the primary care shortage.

Introduction: Short interpregnancy periods increase the likelihood of preterm delivery and low birth weight,1 both of which are significant causes of infant morbidity and mortality.2 Since nearly half of pregnancies in the United States are unplanned,3 opportunities exist to better understand barriers to contraceptive services. Studying these barriers as perceived by clinical staff can better guide programs to improve interpregnancy spacing.
Methods: Between September and November 2017, 76 staff and 95 primary care clinicians from two family medicine residency practices (Highland Family Medicine (HFM) in Rochester, New York and St Margaret Family Medicine (SM) in Pittsburgh, Pennsylvania) completed surveys. Questions assessed perceived barriers to providing contraceptive services, contraception knowledge, and opportunities for improvement. Survey-based analysis focused on comparative descriptive statistics between staff and provider responses.
Results: Clinicians ranked side effects and patient lack of awareness and misconceptions about contraceptive methods more highly than staff (P=0.0073 and P=0.0001, respectively). Staff identified childcare and work absence as more significant barriers (P=0.0114 and P=0.0380, respectively). Providers felt appointment timing was the largest constraint to contraceptive care. Staff perceived financial limitations and scheduling to be the top barriers. Nonclinician staff exhibited significant knowledge gaps regarding contraception.
Conclusions: Numerous modifiable barriers contribute to difficulty providing contraceptive services. Providers and staff largely agree on the perceived barriers, but there is a significant gap in nonclinician staff knowledge of contraception. Education can address one of the leading concerns, but improvement efforts should also address areas such as availability of devices, scheduling issues, and resident supervision.

Introduction: With the estimated future shortage of primary care physicians there is a need to recruit more medical students into family medicine. Longitudinal programs or primary care tracks in medical schools have been shown to successfully recruit students into primary care. The aim of this study was to examine the characteristics of primary care tracks in departments of family medicine. 
Methods: Data were collected as part of the 2016 CERA Family Medicine Clerkship Director Survey. The survey included questions regarding the presence and description of available primary care tracks as well as the clerkship director’s perception of impact. The survey was distributed via email to 125 US and 16 Canadian family medicine clerkship directors. 
Results: The response rate was 86%. Thirty-five respondents (29%) reported offering a longitudinal primary care track. The majority of tracks select students on a competitive basis, are directed by family medicine educators, and include a wide variety of activities. Longitudinal experience in primary care ambulatory settings and primary care faculty mentorship were the most common activities. Almost 70% of clerkship directors believe there is a positive impact on students entering primary care. 
Conclusions: The current tracks are diverse in what they offer and could be tailored to the missions of individual medical schools. The majority of clerkship directors reported that they do have a positive impact on students entering primary care.

Calculating the number of visitor, in a place or room is not easy. In line, it also occurs when we want to count the number of visitors in library. To know whether the number of visitor in library increases or not, the researcher formulated system that was used to count the visitor. It was Haar Like Features method. This method was used to count the number of visitor in library in a day. In this study, Haar Like Features method was implemented to detect human as object. Beacuse of that, it had function as human object ditector and visotor ditector. By using this method, the librarians felt easier when they counted the visitor in a day. They also could calculate whether the number of visitor in library increased or not.
La continuidad ante la crisis. La trayectoria identitaria del peronismo cordobés y los acontecimientos de 2001 en la Argentina
Authors: Reynares Juan Manuel
Published: February 2019

El siguiente artículo indaga sobre la trayectoria identitaria del peronismo
cordobés durante los años 2001 y 2002, es decir, el período de recrudecimiento del ciclo de protesta y movilización social que alcanzó su auge en diciembre de 2001. La literatura que ha estudiado esta etapa tiende a subrayar que no provocó transformaciones sustanciales en la política provincial. El caso cordobés parece caer dentro de esta regla, ya que el peronismo provincial, a la cabeza de una alianza conocida como Unión por Córdoba (UpC), fue reelecto en 2003. Profundizando en lo que supone esa persistencia, el objetivo aquí es rastrear los modos en que este actor político dio sentido a la crisis y planteó posibles soluciones. La conjetura que estructura este artículo es que en 2001 y 2002 la trayectoria identitaria del peronismo cordobés continuó sobre determinada por un discurso neoliberal que había configurado su propuesta de gobierno provincial a fines de los noventa, y que no varió frente a la crisis. Para fundamentar tal hipótesis, se analizará desde la Teoría Política de Discurso la línea política del peronismo cordobés entre 2002 y 2003, comparándola diacrónicamente con su campaña para la gobernación de 1998 y con su fundamentación de la reforma provincial llevada adelante en 2000, para rastrear la continuidad de su trayectoria ante la proliferación de demandas que eclosionó en 2001.

This paper presents main problems of practical implementation of Field
Oriented Control (FOC) developed for an Interior Permanent Magnet
Synchronous Motor (IPMSM). The main sources of Electromagnetic Interferences
(EMI) noises are discussed and practical aspects when a position sensor is
used are presented. The control system is based on the DSP processing unit,
together with inverter and encoder. The main problem addressed in this paper
is reduction of vibrations in torque and speed response in a real system by
re-placing a hardware device of control system very susceptible to EMI
noises, like encoder, with a soft block in control unit like Sliding Mode
Observer, less sensitive to EMI. The experimental results with this control
structure show considerable ripple reduction at steady state in torque,
speed and current, as a consequence of reduction of sensitivity to EMI
noises.
A novel priority based document image encryption with mixed chaotic systems using machine learning approach

Document images containing different types of information are required to be
encrypted with different levels of security. In this paper, the image
classification is carried out based on the feature extraction, for color
images. The K-Nearest Neighbor (K-NN) method of image classification
technique is used for classifying the query Document with trained set of
features obtained from the Document database. Optical Character Recognition
(OCR) technique is used to check for the presence as well as location of
text/numerals in the Documents and to identify the Document type. Priority
level is assigned in accordance with the Document type. Document images with
different priorities are encrypted with different multi-dimensional chaotic
maps. The Documents with different priority levels are diffused with
different techniques. Document with highest priority are encrypted with
highest level of security but Documents with lower priority levels are
encrypted with lesser security levels. The proposed work was experimented
for different document types with more number of image features for a large
trained database. The results reveals a high speed of encryption for a set
of document pages with priorities is more effective in comparison with a
uniform method of encryption for all document types. The National Institute
of Standards and Technology (NIST) statistical tests are also conducted to
check for the randomness of the sequence and achieved good randomness. The
proposed work also ensures security against the various statistical and
differential attacks.
