Data Visualization is widely used to facilitate the comprehension of information and find relationships between data. One of the most widely used techniques for multivariate data (4 or more variables) visualization is the 2D scatterplot. This technique associates each data item to a visual mark in the following way: two variables are mapped to Cartesian coordinates so that a visual mark can be placed on the Cartesian plane; the others variables are mapped gradually to visual properties of the mark, such as size, color, shape, among others. As the number of variables to be visualized increases, the amount of visual properties associated to the mark increases as well. As a result, the complexity of the final visualization is higher. However, increasing the complexity of the visualization does not necessarily implies a better visualization and, sometimes, it provides an inverse situation, producing a visually polluted and confusing visualization—this problem is called visual properties overload. This work aims to investigate whether it is possible to work around the overload of the visual channel and improve insight about multivariate data visualized through a modification in the 2D scatterplot technique. In this modification, we map the variables from data items to multisensoriy marks. These marks are composed not only by visual properties, but haptic properties, such as vibration, viscosity and elastic resistance, as well. We believed that this approach could ease the insight process, through the transposition of properties from the visual channel to the haptic channel. The hypothesis was verified through experiments, in which we have analyzed (a) the accuracy of the answers; (b) response time; and (c) the grade of personal satisfaction with the proposed approach. However, the hypothesis was not validated. The results suggest that there is an equivalence between the investigated visual and haptic properties in all analyzed aspects, though in strictly numeric terms the multisensory visualization achieved better results in response time and personal satisfaction.

Objective: Evaluate the work structure and process in Psychos ocial Care Centers (CAPS) and the professionals profile, the satisfaction, conditions and work overload. Methods: Cross - sectional study conducted in five CAPS in Campina Grande city. The study sample consisted of five coordinators, 42 graduate professional s, 26 mid - level (technical and auxiliary nurses, and caregivers), and the medical records pertaining to 413 users followed up. Data were collected using validated questionnaires (CAPSUL - rating CAPS in southern Brazil) and adapted to the study, between July and October 2014. The questionnaires were double entered and submitted to validation in the sub - program “Validate Epi Info 3.5.4” , used along with the “SPSS 17.0” for processing the statistical analyzes. Measures of central tendency and dispersion were ap plied to the descriptive analyzes; “Fisher's” exact test to check the CAPS impact on hospital admissions and the “Bonferroni” adjusted to verify the diagnoses according to sex. 5% significance level was adopted. The study was approved by the Ethics Committ ee of the Rio Grande do Norte Federal University (UFRN), protocol 719.435, of 05.30.2014. Results: From the structure analysis were identified contextual factors that influenced the work process of CAPS professionals, such as: deficiencies with regard to h uman resources; forms of health professionals employment and qualifications; temporary contract existence. As to process dimension, it was found that the home visits performance by health professionals shows to be ineffective, given its insufficiency and i rregularity, which can be explained by the high demand, reduced staff and transportation lack. It was low coverage of items inherent to Therapeutic Individual Project, as the income generation program, insertion at work and home visit. The reference and co unter reference flow are still not satisfactorily organized. There was statistically significant difference for the diagnosis, with a predominance of mood disorders related to stress among women and those related to alcohol and other drugs among men (p <0. 05). There was an association between the degree of health professionals satisfaction and working conditions, overload and factors related to the content and working conditions, the security measures, comfort and CAPS appearance, contact between the teams and users, families treatment by the teams, temporary employment relationship. Conclusion: The data collected indicate the need for the CAPS organization through increased investments in the sector in order to enhance the infrastructure as potentiating el ement of practices with a view to changing the care model for mental health proposed by the Psychiatric Reform. It is hoped therefore that this research will contribute to better planning in CAPS unit management, with another tool to improve the dimensions involving the structure and the professional work process and improve this mental health care model.

This research aims to systematize a proposal of developing a mobile tablet application in order to help implementing the Semantic Differential technique – SD, under the approach of Participatory Design. In 1975, Osgood et al. created the Semantic Differential technique. Since then, many experiments use it to measure the affective perception of individuals concerning objects and concepts by means of compounded scales of bipolar adjectives, based on the theoretical models that support the technique: the conductible, spatial and metric models. During the application of the technique with potential users, the researcher must simultaneously manage several contexts, that is, audio recorder, when authorized, and observe and record spontaneous reports of the respondent. It is noticeable that often occurs a cognitive overload during this event. Thus, the use of a single application whose interface is assigned to its users and respondents could assist researchers in applying the SD technique. This research aimed to understand the processes inherent to the task of implementing the Semantic Differential technique and obeyed the following steps: a) training of users, b) background questionnaire c) interview with Focus Group, and d) cooperative evaluation. Besides these procedures, one can also observe the degrees of facilitation or difficulty concerning the use of the conventional model, which is the development and application of scales with the aid of printed material, pencil, pens, clipboards, and recorder software for editing the document and data analysis. This paper comprises reactions and impressions from the experiences of users of SD technique. Considering the data recollected from the user’s observation, the hypothesis of the experiment proved to be right. It means that the development of the application for mobile tablet employing the technique of Semantic Differential is viable, since it assembles all the steps in one only tool, increases the accomplishment of the task between user/researcher and user/respondent resulting in their mutual satisfaction.

The interprofessional education still represents a great challenge for the health education. This paper aims at implementing the Interprofessional Cardiology Visit (VIC, acronym in Portuguese) as a teaching strategy for the interprofessional education in the undergraduate and graduate courses of UFRN (Federal University of Rio Grande do Norte, acronym in Portuguese). It is a prospective and exploratory study held from March 2013 to November 2014, in the cardiology department of HUOL (Portuguese acronym for Onofre Lopes University Hospital), including health professionals from the mentioned hospital (doctor, psycologist, physiotherapist, dentist, social assistant, nutritionist, pharmacist and nurse), undergraduate and graduate students from the health courses of UFRN. The study happened in three parts: interprofessional activity planning; Implementation of the activity “Interprofessional Cardiology Visit (VIC)”; and Activity evaluation, this last one was made through focus groups. The process of planning and implementation of the VIC was described during the implementation phase: 60 meetings in which 1324 participants discussed one specific patient per meeting. After each case presentation, an interprofessional discussion was held, pointing out each professional’s specific point of view towards improving the overall care of that discussed patient. From the focus group analysis, five categories emerged: Recognition of previous participations in interprofessional activities; Conceptual vision of interprofessional activities; Impacts of the VIC to the patient’s care; Contributions of VIC to the professional training; and Challenges of VIC continuation. The making and planning of VIC process has reached its goals, despite of some health professional’s participation not being systematic due to work overload, such as the nurses’ case, as well as schedule difficulties. The VIC was praised as a successful experience and considered an initiative with positive impact for improving the care of patients with heart diseases. It is clear, from analyzing the discourses, that the VIC is a strategy which positively impacts both the care and the teaching. However, some difficulties remain, such as the lack of human resources and the challenge of making it systematic.

The process mapping is an important tool in the management of organizations, allowing better levels of productivity, quality and reciprocity concerning the implementation and decision-making. It benefits in a clear way the process organization and assures the manager a macro vision of the system. In this sense, the objective of this study is to describe the mapping process as it occurs in the Januario Cicco Maternity School–MEJC. The bibliographic and descriptive research included interviews, observations and researches in many databases. The study analyzed the limiting points of the detected flow trying to find a better comprehension of the flow of patients in the maternity in order to offer the gestors the information necessary to improve the quality of the assistance as well as a general view of the flow of patients and any change detected there. As a result, we believe that the process mapping may become a relevant factor to the organizational management of MEJC, in view that it is an element that can contribute to ease up the management of information studied, considering that the perfect change of information inside a complex system will produce improvements in all spheres of this institution.

The spread of wireless networks and growing proliferation of mobile devices require the development of mobility control mechanisms to support the different demands of traffic in different network conditions. A major obstacle to developing this kind of technology is the complexity involved in handling all the information about the large number of Moving Objects (MO), as well as the entire signaling overhead required to manage these procedures in the network. Despite several initiatives have been proposed by the scientific community to address this issue they have not proved to be effective since they depend on the particular request of the MO that is responsible for triggering the mobility process. Moreover, they are often only guided by wireless medium statistics, such as Received Signal Strength Indicator (RSSI) of the candidate Point of Attachment (PoA). Thus, this work seeks to develop, evaluate and validate a sophisticated communication infrastructure for Wireless Networking for Moving Objects (WiNeMO) systems by making use of the flexibility provided by the Software-Defined Networking (SDN) paradigm, where network functions are easily and efficiently deployed by integrating OpenFlow and IEEE 802.21 standards. For purposes of benchmarking, the analysis was conducted in the control and data planes aspects, which demonstrate that the proposal significantly outperforms typical IPbased SDN and QoS-enabled capabilities, by allowing the network to handle the multimedia traffic with optimal Quality of Service (QoS) transport and acceptable Quality of Experience (QoE) over time.

Preterm birth is a public health problem worldwide. It holds growing global incidence rates, high mortality rates and a risk of the long-term sequelae in the newborn. It is also poses burden on the family and society. Mothers of very low birth weight (VLBW) preterm infants may develop psychological disorders, and impaired quality of life (QoL). Factors related to mothers and children in the postpartum period may be negatively associated with the QoL of these mothers. The aim of this study was to assess factors possibly associated with the QoL of mothers of VLBW preterm newborns during the first three years after birth. Mothers of VLBW preterm answered the World Health Organization Quality of Life (WHOQOL)-bref and the Beck Depression Inventory (BDI) in five time points up to 36 months postpartum, totalizing 260 observations. The WHOQOL–bref scores were compared and correlated with sociodemographic and clinical variables of mothers and children at discharge (T0) and at six (T1), twelve (T2), 24 (T3) and 36 (T4) months after the delivery. We used the Kruskal Wallis test to compared scores across different time points and correlated WHOQOL-bref scores with the sociodemographic and clinical variables of mothers and preterm infants. Multiple linear regression models were used to evaluate the contribution of these variables for the QoL of mothers. The WHOQOL–bref scores at T1 and T2 were higher when compared to scores in T0 in the physical health dimension (p = 0.013). BDI scores were also higher at T1 and T2 than those at T0 (p = 0.027). Among the maternal variables that contributed most to the QoL of mothers, there were: at T0, stable marital union (b= 13.60; p= 0.000) on the social relationships dimension, gestational age (b= 2.38; p= 0.010) in the physical health dimension; post-hemorrhagic hydrocephalus (b= -10.05; p= 0.010; b= -12.18; p= 0.013, respectively) in the psychological dimension; at T1 and T2, Bronchopulmonary dysplasia (b= -7.41; p= 0.005) and female sex (b= 8,094; p= 0.011) in the physical health dimension and environment, respectively. At T3, family income (b= -12.75’ p= 0.001) in the environment dimension, the SNAPPE neonatal severity score (b= -0.23; p= 0.027) on the social relationships dimension; at the T4, evangelical religion (b= 8.11; p= 0.019) and post-hemorrhagic hydrocephalus (b: -18.84 p: 0.001) on the social relationships dimension. The BDI scores were negatively associated with WHOQOL scores in all dimensions and at all times points: (-1.42 ≤ b ≤ -0.36; T0, T1, T2, T3 and T4). We conclude that mothers of preterm infants VLBW tend to have a transient improvement in the physical well-being during the first postpartum year. Their quality of life seems to return to levels at discharge between two and three years after delivery. The presence of maternal depressive symptoms and diagnosis of post-hemorrhagic hydrocephalus or BDP are factors negatively associated with the QoL of mothers. Social, religious and economic variables are positively associated with the QoL of mothers of VLBW preterm.

Los cambios que trae aparejada una ruptura conyugal en las relaciones paterno-filiales es un hecho ampliamente documentado. La literatura especializada sobre el tema ha tendido a analizar estos cambios, desde un lenguaje de la cuantificación, midiendo presencias y ausencias paternas postdivorcio bajo recuentos de contacto y visitas entre padres y progenie. Lo que este tipo de estudios no dan suficiente cuenta es del tipo de expectativas y prácticas parentales que están detrás de ese mayor o menor contacto paterno- filial. Y más concretamente, el tipo de dinámicas postdivorcio asimétricas que se desencadenan a partir de una herencia conyugal de desequilibrio parental. Si bien se ha documentado extensivamente el fenómeno de la "deserción paterna" postdivorcio, enescasas ocasiones se ha profundizado sobre las raíces de esta dinámica parental, unas raíces que han de buscarse en paradigmas de biparentalidad complementarios y asimétricos que en muchos casos se venían ejercitando desde la conyugalidad y en el que el habitus de madre sobrecargada y padre ausente era una dinámica fuertemente asentada. El presente trabajo explora las implicaciones postdivorcio de estas divisiones y habitus parentales en procesos de ruptura conyugal. Sostenemos la tesis de que los desequilibrios parentales matrimoniales no tienden a desaparecer ante un contexto de divorcio, sino que con frecuencia se manifiestan con mayor radicalidad bajo formas trianguladas y en la mayoría de los casos de sobrecarga materna. Es esta mediación y casi obligada presencia materna la que permite comprender en clave cualitativa las resoluciones paterno-filiales postdivorcio y el mayor o menor grado de implicación paterna posterior. Estas conclusiones se extraen de una investigación doctoral que analiza en profundidad las experiencias postdivocio de 20 familias vascas. Sus relatos y vivencias ofrecen evidencia empírica de las complejas y persistentes asimetrías de género que el divorcio termina por consolidar

A Vincristina (VCR) é um quimioterápico amplamente utilizado na clínica. Alteraçoes imunológicas sao alguns dos efeitos do quimioterápico mais apresentados pelos pacientes. O presente estudo tem como objetivo avaliar se o exercício aeróbico prévio (6 semanas de nataçao, 1h/dia, 5 dias/semana, sobrecarga de 5 do peso corporal) poderia melhorar os déficits imunológicos em ratos Wistar posteriormente tratados com o quimioterápico Vincristina. A administraçao da Vincristina foi realizada com dose única semanal de 0,5mg/kg, durante duas semanas, com dose acumulada de 1mg/kg, via intraperitoneal. No 15o dia os ratos foram submetidos à retirada de sangue para análise do sistema imunológico pelo hemograma e dano ao DNA pelo teste Picogreen. Observou-se uma diminuiçao significativa no número de leucócitos, plaquetas e nos níveis de eritrócitos nos ratos tratados com o quimioterápico, assim como significativo dano no DNA celular. No entanto, o exercício foi capaz de proteger dessa diminuiçao das células do sistema imune e do dano causado ao DNA no grupo que praticou o exercício e recebeu o quimioterápico. Portanto, o exercício físico mostrou-se protetor contra a diminuiçao das células do sistema imune e dano ao DNA causado pelo tratamento com o quimioterápico em ratos

A Vincristina (VCR) é um quimioterápico amplamente utilizado na clínica. Entre os efeitos colaterais descritos, devido a sua toxicidade, estao às alteraçoes do equilíbrio e na coordenaçao motora. O presente estudo tem como objetivo avaliar o efeito do exercício aeróbico prévio (6 semanas de nataçao, 1h/dia, 5 dias/semana, sobrecarga de 5 do peso corporal) em aspectos comportamentais de ratos Wistar tratados com o quimioterápico Vincristina. A administraçao da Vincristina foi realizada com dose única semanal de 0,5mg/kg, durante duas semanas, com dose acumulada de 1mg/kg, via intraperitoneal. Um dia e 7 dias depois de cada dose os ratos foram avaliados com testes de equilíbrio (Rotarod), de exploraçao (Campo Aberto) e de força muscular (Grip-Test). Observou-se uma diminuiçao significativa do equilíbrio corporal e do comportamento exploratório nos ratos expostos à vincristina com proteçao significativa do exercício físico. Nao houve diminuiçao significativa da força muscular nos ratos tratados com VCR, porém o exercício por si só aumentou a força muscular e a distancia percorrida pelos ratos que fizeram nataçao. Portanto, o exercício físico mostrou-se protetor contra a perda de equilíbrio e diminuiçao da exploraçao observada nos ratos expostos ao quimioterápico
