Sistemas de gerenciamento de bibliotecas: riscos decorrentes do processo de migração de dados

This work aims to analyze risks related to information technology (IT) in procedures related to data migration. This is done considering ALEPH, Integrated Libray System (ILS) that migrated data to the Library Module present in the software called Sistema Integrado de Gestão de Atividades Acadêmicas (SIGAA) at the Zila Mamede Central Library at the Federal University of Rio Grande do Norte (UFRN) in Natal/Brazil. The methodological procedure used was of a qualitative exploratory research with the realization of case study at the referred library in order to better understand this phenomenon. Data collection was able once there was use of a semi-structured interview that was applied with (11) subjects that are employed at the library as well as in the Technology Superintendence at UFRN. In order to examine data Content analysis as well as thematic review process was performed. After data migration the results of the interview were then linked to both analysis units and their system register with category correspondence. The main risks detected were: data destruction; data loss; data bank communication failure; user response delay; data inconsistency and duplicity. These elements point out implication and generate disorders that affect external and internal system users and lead to stress, work duplicity and hassles. Thus, some measures were taken related to risk management such as adequate planning, central management support, and pilot test simulations. For the advantages it has reduced of: risk, occurrence of problems and possible unforeseen costs, and allows achieving organizational objectives, among other. It is inferred therefore that the risks present in data bank conversion in libraries exist and some are predictable, however, it is seen that librarians do not know or ignore and are not very worried in the identification risks in data bank conversion, their acknowledge would minimize or even extinguish them. Another important aspect to consider is the existence of few empirical research that deal specifically with this subject and thus presenting the new of new approaches in order to promote better understanding of the matter in the corporate environment of the information units

Relações entre perfil de valores e perfil de uso da tecnologia: Um estudo com os docentes que atuam na modalidade presencial e/ou no ensino a distância

O advento das novas tecnologias e a dinamicidade das mudanças que estas provocam, impactam diretamente em vários aspectos da sociedade, dentre estes, na educação. Novas metodologias e mudanças no processo de ensino-aprendizagem tornam-se práticas cada vez mais frequentes neste campo. O elemento basilar desta nova constituição é o docente, capaz de transformar a utilização desses recursos em ferramentas que favoreçam o processo educativo. Essa readequação do comportamento exigida por essas constantes mudanças é orientada pelos valores pessoais dos sujeitos que vivenciam a situação. Os valores são idealizados como critérios que interferem diretamente nas atitudes, preferências e até mesmo no comportamento humano, influenciando no modo como o indivíduo interpreta as suas próprias atitudes e as dos outros, inclusive no âmbito profissional. Dessa forma, o objetivo geral da presente pesquisa é analisar as relações entre o perfil de uso da tecnologia e os valores dos docentes da UFRN Universidade Federal do Rio Grande do Norte, baseado na escala de valores de Schwartz. Para isso foram utilizados os tipos motivacionais que compõem a teoria de valores de Schwartz, através de questionário aplicado junto aos docentes. Trata-se de uma pesquisa de enfoque analítico quantitativo que utiliza um questionário da escala de valores desenvolvida por Schwartz et al. (2001) conhecida como PVQ (Portrait Values Questionnaire). A pesquisa foi desenvolvida a partir de uma amostra de 200 docentes entre atuantes da modalidade presencial e/ou na modalidade de ensino a distância. A estratégia de análise dos dados utilizou técnicas de estatística descritiva, análise de gráficos, análise das frequências relativas e a técnica estatística MANOVA (Análise Multivariada de Variância). Os resultados apontaram que os docentes utilizam moderadamente os recursos tecnológicos avaliados nesta pesquisa, como ferramenta de apoio pedagógico. Com relação ao perfil de valores, os docentes apresentaram prioridade entre os tipos motivacionais Autodeterminação, Benevolência e Universalismo, enquanto os menos priorizados foram os de Tradição, Realização e Poder, respectivamente. Contudo, não foram identificadas relações significativas entre o perfil de valores e o perfil de uso da tecnologia entre os docentes estudados nesta pesquisa

A implementação de ações de integração na segurança pública: o caso das polícias civil e militar do Rio Grande do Norte

The research aimed to understand the challenges for the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP. This study aimed to explore the gap with regard to the deepening of the possible causes that may hinder the implementation of integrated working between the police in public security, through a specific analysis on the state of Rio Grande do Norte. Was based on a theoretical framework that includes policies: general concepts, the steps of a public policy, the implementation stage , public security : conceptual definitions, policies on security in Brazil, the structure of public security in Brazil and systems police, Military Police x Civil Police: Roles and conflicts , integrating public security: the challenges to be overcome, the Unified public Safety (SUSP) and the main difficulties in the integration of the police. Being classified as to the purposes as an exploratory research on how to approach ranks as qualitative. The research unit was the Center for Integrated Operations Public Safety (CIOSP) through three subjects who were the chief CIOSP, the representative of the military police acting with the CIOSP, and representative civil police also active with the CIOSP. These subjects were chosen because of the understanding that individuals occupying senior positions would have more ability to respond to questions that guide the research problem. Data were collected through a set of interviews, qualitative data analysis was performed based content analysis, based on the definition of categories of analysis, gated time cross. With the results, it was revealed that the main problems of integration between the state police are treatment protocols, lack of political will and lack of infrastructure. The relationship between the Military Police and Civil Police in Rio Grande do Norte has differing cultural aspect, but can be considered as good value, professionalism and integrated operations. The implementation of CIOSP-RN followed the characteristics of the top-down model, the main difficulties in implementing the proposals of the SUSP, lack of own resources, the lack of standardization in public safety and the lack of professional training of public safety. It was concluded that with respect to the challenges to the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP, the actions follow the characteristics of the top-down model, with no autonomy of administrators public to say in decisions, which restricts the view of the public safety of the state

Qualidade do ar interior e conforto térmico : um estudo em espaços de estacionamento em Natal/RN

The recent tendency to utilize parking lots for other purposes has demonstrated that more time has been spent by visitors, mainly in great cities. Therefore, this paper investigates the thermal comfort and the air quality indoors in areas specifically used as parking lots by analyzing the direct relation between such environments and vehicular pollution. The thermal comfort and the quality of air indoors in parking lots with different architectonic typology (ground-floor and underground) are also studied, aiming to contribute to the proposition of suitable new areas designated to human usage. Field research was done, in two distinct periods within different weather conditions (January and July) in, two naturally cooled, parking lots located in Natal - RN. The internal environment agents were measured by using tools for air temperature, humidity, speed and direction; interviews with employees and visitors and chemical analysis through appropriate tools to analyze specific material, carbon monoxide and ozone. The results showed that chemical agents densely concentrate mostly in the closed parking space, aggravated by weather conditions, which dissatisfied the visitors. Still, it was shown that architectonic typology, alongside topographical aspects compromise internal environmental conditions, which increases the retention of pollution, leading to dissatisfactory thermal comfort levels and becoming less suitable for usage by visitors considering air and thermal comfort aspects. Consequently, they are not suitable for human stay due to the poor quality of the indoor air

Influência do tempo e dose de heparina em modelo de peritonite aguda

In the last years, heparin has become target of many studies related to inflammation due its ability of biding to proteins involved on immune response. Recently, it was demonstrated, at our laboratory, using a thIoglycollate-induced peritonitis model, heparin s capacity of reduce cellular influx into the peritoneal cavity, 3 hours after the inflammatory stimulus. Once neutrophilic infiltration is highest around 8 hours after the inflammatory stimulus, at the present work, using the same peritonitis model, it was assessed heparin s ability of keeping the interference on leukocyte infiltration, 8 hours after inflammation induction. Moreover, using cellular differential count, it was evaluated how the cellular populations involved in the inflammatory process would be affected by the treatment. Eight hours after the inflammatory stimulus, only heparin dosage of 1 μg/Kg was able to reduce the cellular influx to peritoneum, 62.8% of reduction when compared to positive control (p < 0.001). Furthermore, heparin dosage of 15 μg/Kg presented a pro-inflammatory effect in whole blood verified by the increase of 60.9% (p < 0.001) and 117.8% (p < 0.001) on neutrophils and monocytes proportion, respectively, when compared to positive control. In addition, this dosage also presented a neutrophilic proportion on peritoneal fluid 27.3% higher than positive control (p < 0.05). This duality between anti- and pro-inflammatory effects at different times corroborates studies that attribute a pleiotropic immunomodulator role to heparin.

Cinemática de partículas em fluidos de viscosidade variável com o tempo e sua aplicação na construção de poços de petróleo: avaliação durante paradas operacionais

The new oil reservoirs discoveries in onshore and ultra deep water offshore fields and complex trajectories require the optimization of procedures to reduce the stops operation during the well drilling, especially because the platforms and equipment high cost, and risks which are inherent to the operation. Among the most important aspects stands out the drilling fluids project and their behavior against different situations that may occur during the process. By means of sedimentation experiments, a correlation has been validated to determe the sedimentation particles velocity in variable viscosity fluids over time, applying the correction due to effective viscosity that is a shear rate and time function. The viscosity evolution over time was obtained by carrying out rheologic tests using a fixed shear rate, small enough to not interfere in the fluid gelling process. With the sedimentation particles velocity and the fluid viscosity over time equations an iterative procedure was proposed to determine the particles displacement over time. These equations were implemented in a case study to simulate the cuttings sedimentation generated in the oil well drilling during stops operation, especially in the connections and tripping, allowing the drilling fluid project in order to maintain the cuttings in suspension, avoiding risks, such as stuck pipe and in more drastic conditions, the loss of the well

Metodologia para avaliação de cinemática de partículas gasosas em fluidos de viscosidade variável com o tempo e sua aplicação na construção de poços de petróleo

Many challenges have been presented in petroleum industry. One of them is the preventing of fluids influx during drilling and cementing. Gas migration can occur as result of pressure imbalance inside the well when well pressure becomes lower than gas zone pressure and in cementing operation this occurs during cement slurry transition period (solid to fluid). In this work it was developed a methodology to evaluate gas migration during drilling and cementing operations. It was considered gel strength concept and through experimental tests determined gas migration initial time. A mechanistic model was developed to obtain equation that evaluates bubble displacement through the fluid while it gels. Being a time-dependant behavior, dynamic rheological measurements were made to evaluate viscosity along the time. For drilling fluids analyzed it was verified that it is desirable fast and non-progressive gelation in order to reduce gas migration without affect operational window (difference between pore and fracture pressure). For cement slurries analyzed, the most appropriate is that remains fluid for more time below critical gel strength, maintaining hydrostatic pressure above gas zone pressure, and after that gels quickly, reducing gas migration. The model developed simulates previously operational conditions and allow changes in operational and fluids design to obtain a safer condition for well construction

Efeito antitrombótico de uma fucana não anticoagulante extraída da alga Spatoglossum Schröederi

Fucan is a term used to denominate a family of sulfated L-fucose-rich polysaccharides. The brown alga Spatoglossum schröederi (Dictyotaceae) has three heterofucans namely fucan A, B and C. The 21 kDa fucan A is composed of a core of β (1-3) glucuronic acid-containing oligosaccharide of 4.5 kDa with branches at C4 of fucose chains α (1-3) linked. The fucose is mostly substituted at C4 with a sulfate group and at C2 with chains of β (1-4) xylose. This fucan has neither anticoagulant (from from 0.1 to 100µg) nor hemorrhagic activities (from 50 to 800 µg/mL). The antithrombotic test in vivo showed the fucan A has no activity in any of the concentrations (from 0.2 to 20µg/g/day) tested 1h after polysaccharide administration. However, when fucan A was injected endovenously 24h before the ligature of the venae cavae, we observed a dose-dependent effect, reaching saturation at around 20g/g of rat weight. In addition, this effect is also time-dependent, reaching saturation around 16h after fucan administration. In addition, regardless of administration pathway, fucan A displayed antithrombotic action. The exception was the oral pathway. Of particular importance was the finding that fucan A stimulates the synthesis of an antithrombotic heparan sulfate from endothelial cells like heparin. The hypothesis has been raised that in vivo antithrombotic activity of fucan A is related to the increased production this heparan. Taken together with the fact that the compound is practically devoid of anticoagulant and hemorrhagic activity suggests that it may be an ideal antithrombotic agent in vivo

Tempo livre de lazer e composição corporal de escolares do meio-oeste catarinense

The aim of this study was to investigate the relationship between free time for leisure and body composition of students in the crucial ninth year. (N = 228) of towns in the Midwest catarinense. We used the Adolescent Behavior Questionnaire of Santa Catarina (COMPAC) to assess lifestyle, considering that Active schoolchildren during the week, accumulated 300 or more minutes of moderate or vigorous physical activity (MVPA). Were used the time to 2 hours or more / day to determine the time of excessive use of TV and computer video game. To analyze body composition were used two criteria: the Body Mass Index (BMI) and sum of skinfolds (EDC). It was observed a proportion of 67.3% of girls and 68.7% of boys assets and more than 98% of students were using excessive TV time, computer and video game. In the classification by EDC, most of the boys showed great or low levels of body composition, while more than half of girls were classified at higher levels. As for BMI, most boys and girls had not overweight. Significant difference in the comparison of total minutes per week of MVPA reported between the groups, the second criterion of EDC and BMI for girls but not for BMI in boys. It is concluded that students with higher accumulation in minutes of MVPA showed better body composition indicators, but no significant difference was found when compared active groups with inactive, according to criteria used.

Visões da cidade : da cidade histórica aos bairros da Cidade Alta e Ribeira em Natal-RN

The present work is an initiative of undertaking a perspective that values the aspects of the city in its diversity. The one that t intends is to discuss the urbanity starting from the aspect of the image, of the history, and about main point, to value the point of the individual's view that lives the urban space in its more several configurations: the house, the street, the neighborhood, and the city in wider scale. The described historical research defines the city as space of the human accomplishments. When analyzing the moments of the most recent history of the urban life the modernity/post-modernity notions they are explored in the sense of illuminating the wealth, continuity and it breaks of patterns of behavior, and on the other hand, to describe a I overfly in the several times of the city. The prominences of aspects of the archaeology and of the descriptive resource they are related, for its time, the most punctual perspective of the practical research, the instance of the neighborhood, specifically High City and Riverside, configuring an immersion in the daily more punctual of the city, valuing forms of being, aiming the perspective of the personal computer as point-of-view. The images of the city assume the paper of representing the documental about the current features of the urbanity. It is without a doubt that at the present time the photographic image already possesses a paper of prominence it is as research instrument, be as main source for a work on files of photos. The photographic images in the present work possess a prominence place, focusing specific places of the city in the time. Finally, the individual's voice valued under the perspective on as the person's knowledge that inhabits and live the urbanity he/she understands the knowledge of the life in the city and, more than in any other place, a middle where the loss of action models is pointed very easily tends in view the dynamic movement of the practices and renewal of new indications; in the same space in that becomes urgent to build marks starting from which the individual can shimmer the future. And in that space the individual's voice is valued as rich source of information on living the scenery of conflicts of the present time

Memória e cultura: os Fulni-ô afirmando identidade étnica

Ce travail s agit du processus d´affirmation de l´identité Fulni-ô et de la mobilisation ethnique du groupe qui sont organisées et maintenues en bénéfice de leurs droits; ceux-ci consistent en la reconnaissance comme indiens devant la société et leurs droits sur le territoire. Le groupe est situé dans la municipalité d´Águas Belas, localisé entre l´ agreste et le sertão de l´état du Pernambuco. Ce sont, en moyenne, 3.676 indiens qui présentent comme signes d´identification ethnique: le Yathê, langue spécifique du groupe qui continue à être utilisée au quotidien; l´Ouricuri, terme qui désigne le rituel qui a lieu pendant le printemps et pendant des périodes spécifiques de l´année; le Toré, danse commune aux indiens du Nordeste. La mémoire et la matière culturelle sont les signes de mobilisation ethnique sélectionnés par les Fulni-ô pour favoriser l´affirmation de leur identité et la protection de leurs droits. Cet aspect sera traité tout au long de ce travail. La mobilisation ethnique est permanente, les Fulni-ô ne cessent d´utiliser des moyens qui peuvent les aider à vivifier leur identité et à protéger l´intégrité de leur territoire. Au travers de la mémoire ou grâce à l´utilisation de signes et de symboles ethniques (comme la langue, le rituel religieux et le Toré) ils consolident l´idée qu´ils sont indiens en même temps qu´ils établissent et défendent leurs frontières ethniques et physiques

Gestão participativa em educação: compasso e descompasso de uma experiência de democracia no espaço escolar

This work aims at investigating the strategies of management used by State School Joaquim Jose de Medeiros, located in the city of Cruzeta - RN, as award practice of "School of Reference in Management", with a state title in 1999 at the beginning of the decade from 2000, being "Outstanding Brazil" from best management strategies nationally. In 2005, it is ranked among the best experiences of the state. It has been become complex by experiencing in that institution, but at the same time an enjoyable practice, mainly by using a social research, in a qualitative and quantitative approach, and a analysis of the institutional performance of two management practices: from 1995 to 2002 and from 2003 to 2007 . To understand the object, a investigative questionnaire was used with representatives of the school community and carried out an analysis of assessment of institutional and documents of institutional organization of the periods above in order to identify management strategies and examine the influences of the share capital, public policies , the institutional evaluation, in the process of democratic construction that has allowed achievements, highlighting Cruzeta, in the Seridó in the state of Rio Grande do Norte, semi-arid northeast, in the national and international juncture of well-successful experiences in management in institutional categories and leadership. This study becomes relevant to allow understand that the cultural practices of seridoenses that symbolize a capital generated by principles of trust, reciprocity, civic culture, as a driving force in overcoming the problems community and the conquest of democratic principles, worked for the school become a national reference in educational administration. Another aspect that made it natural that school was the collective creation of educational project with the participation and civic culture of self-evaluation as a way to understand the institutional practice and establish guidelines to improve the teaching and practice management in its many dimensions educational, social, administrative - financial and legal

Um olhar sociológico sobre a criança e o brincar: espaço e tempo de construção, reinvenção e aprendizagem

This research I discuss the play, also talking with the other subjects that make up the universe in which the play is inserted, such as family, school and culture. The fundamental proposition of this dissertation assumes that the absence of play in children's lives affect their physical structure, psychological, biological, cultural, social, historical and theirs development. The initial questions were: What are the spacetimes reserved in the school for play? What is the importance of play in the development of children? Does the school recognize the importance of play in its social space? How the children perceive and use the spacetimes to play at school? Are there spacetimes at school to play? This is a theoretical and empirical research of exploratory study. The research‟s field was the Municipal School Professor Ulysses Góes, located in district of Nova Descoberta, in Natal, Rio Grande do Norte and, as research techniques, I used: participant observation, photography, structured interviews with students and questionnaires with teachers. The results indicate that for most of children, the school allows the play, few disagree with this preposition.Teachers recognize the importance of play in school, but for various reasons do not provide your practice. The dissertation points the possibility of new studies and developments for the theme.

Em busca do tempo partido: a consciência histórica e o MST

The work that follows is dedicated to the study of the historic time experience by the political militancy from our time. The political militant from the left-wing is the one that denies the state of current things, recovering a historic experience located far before its time and projecting a future beyond the incessant reproduction of the present relations. We chosen the Landless Workers Movement, not as study object, but as specific place where this consciousness is made and can be comprehended. The historic consciousness study of the landless militancy is, for us, the best starting point to understand the magnification of the historical time operated on the change of social relations lived inside an organization. The time division between before and after, as well as the history being understood as a progress isn t a natural given data, but a construction that obeys the contradictions of the present. It, therefore, must understand how the present lived by the militancy operates changes on the consciousness of time. From documents, reference books, formation notebooks and several materials produced by MST, we try to understand the way that the movement tells his history and lists with this wider experience of the struggle for the change of the current social order. Similarly, when we hear reports of history of several militants, we try to comprehend how this wider narrative re-orients the sight over history himself, over the experience of contradictions on before and after making the landless militant
