This work presents the results of a survey on narrative features found on contemporary Venezuelan documentary, specifically, the feature and medium length (over 30 minutes) films released in Venezuelan theaters between 2005 and 2013. We go through the work of several film critics who have written about Venezuelan documentary from the 1960s to the 1990s. In the critical review of this framework, we distinguished paradigmatic moments of documentary activity in the country, which unfold in particular forms and practices of representation. These paradigms, practices and forms dialogue with our contemporary corpus and allow us to identify three sets of films: one of leftist and militant documentaries; another, of works revolving a nationalist-populist paradigm; and finally, one we call of "ideological diversity", which moves away from the representation of Venezuelan working classes and the popular culture. The thesis describes ideological, aesthetic, narrative and thematic peculiarities of these three groups of films, and produces a film analysis of three titles, each of them belonging to one of these groups.

Characterization studies on how are being conducted the educational service and the service of social assistance provided to people with disabilities, as well as the way it has been taking place the relationship between these services are still rare. Studies with such outbreaks could contribute to a better understanding of how the sessions are taking place and if they are in line with public policies, achieving the expected goals with people with disabilities and provide insight for the improvement of care. The research aimed to characterize and analyze the educational service and social assistance offered to a group of students with disabilities, from the parents’ perspective and of the teachers of room of resources. Participants were seven mothers of disabled students attending schools in the state system of public education and two resource room teachers, one active in teaching disabled hearing and visually impaired and other disabled in intellectual education. Among the seven students attending the resource room, four were enrolled in primary school and three in high school, aged between 10 and 17 years. Among the students two have hearing loss, two have learning difficulties, one has visual impairment, one has intellectual disabilities and one has multiple disabilities. To collect data we used two interview scripts containing questions regarding the characteristics and assessments of mothers and resource room teachers on the educational service and social assistance provided to students. The results for the educational services indicate that mothers perceive the Specialized Educational Services (SES) held in the resource room as the main teaching condition for the children learning guarantee, moreover, expressed satisfaction with care and with close contact with the SES of teachers. The teachers' reports indicate that the SES seek help students over come difficulties and to support academic learning; indicate the need more time and frequency to meet each student; report that communication with teachers of regular classes is infrequent and the contact from the school personnel with the social worker does not occur, and the teacher considers that the family should be responsible for seeking the service of social assistance. The results show that 57% of students receive social assistance benefits as the Continuous Cash Benefit (CCB) and benefits of Bolsa Família Program (BFP). Discusses the improvements required for the actions of those involved in care remain in line with the actions and objectives set forth in the special education policy and social assistance policy.

The purpose of this work is to check if and how the strategic planning of information technology occurs in organizations of the Federal Public Administration (FPA) from the case study of the elaboration, implementation and control of the Director of Information Technology Plan (DITP) in the Federal Institute of Education, Science and Technology of Sao Paulo. The mandatoriness of preparing this strategic plan comes from the planning needs in public authority in the Federal Constitution of 1988 and also from the prerogatives of the Reform of the Public Management of 1995, which introduced the New Public Management (NPM) character of management from the results in the FPA. The methodology consisted of a case study with members of the Information Technology Committee from the Federal Institute of Education, Science and Technology of São Paulo, whose members are Coordinators of Information Technology (CIT) of all campuses of the organization. This committee is responsible for IT policies and preparing the DITP. The data collection procedure as well as the bibliographic and documentary research were the field research, by carrying out in-depth interview with the Chair of the IT Committee and the questionnaire application with the CIT. The main focus of this research is to verify the perception of the CIT campuses in the studied institution because they are responsible for disseminating the goals prescribed in this planning and for the checking if the goals are being fulfilled in the units in which they work as IT professionals. The main results found that many of the interviewed people are not aware of the DITP and the strategic issue that is linked to this document and that they make it just an operational document reduced to a mere instrument for the legal and bureaucratic compliance with the acquisition of goods and IT services.

The central theme of this study is the technical and administrative work in education of assistant position occupants in administration at the Federal University of São Carlos (UFSCar), São Carlos campus, who have experienced the removal process. We aimed to identify feelings of pleasure and suffering experienced by servers and verify the defensive strategies they used to cope with the feelings of suffering arising from the work environment. Under the theoretical aspect, the study references the dejourian’s Psychodynamics Work, a line of studies that has been used by different areas of knowledge in the characterization of the elements present in the experience of the workers. Suffering at work is a ubiquitous phenomenon of nature, and has been the subject of research in a variety of occupations. From this perspective, the public servant of Federal Institutions of Higher Education (IFES) covers this scenario. In terms of methodology, a study was conducted based on exploratory research, qualitative approach, using the case study method in a sample of eight subjects. The central categories of analysis were suffering, pleasure, labor relations, recognition and defense strategies of the servers facing labor contingencies. A thematic content analysis was made, based on various aspects of the daily work of the administrative assistant, such as the stigma of a public servant; seasonality of managers; patrimonialist behaviors; taking work thoughts home; political influence; bullying; somatization; the intensification of work; and the invisibility of middle activities. These were suffering indicators of servers. Among the pleasure indicators stood out working conditions; the symbolic fee; the public space for discussion; work in an educational institution. In this plot of pleasure and suffering, recognition appears as an essential element. It was possible to point to the ambivalence in labor relations and daily autonomy in the workplace. The main strategies to deal with adversity and suffering were prioritizing the study; verbalize problems; documenting complaints; coping; isolation; and indifference. We consider work as a central element in the ability of the worker to establish himself as a social being. The results allowed the understanding of different aspects of the work of TAE server, from the experiences of pleasure and suffering, passing by the intersubjective relations of the same. In the cutting we made, the removal was successful in most cases, helping this professional category in the redefinition of work, as well as the preservation of health. However, there were also cases where the removal accentuated possible suffering experiences. This study made expanding the universe of work psychodynamics knowledge possible in this professional category, revealing the processes in mental and social-relational scope involving the meanings of work for man.

Prefabricated building systems in Light Steel Frame - LSF are widely used in developed countries like England, Japan and USA. As constructive process, the LSF shows a progress compared to the traditional system is characterized by being an industrial building, rationalized with high productivity and require one skilled labor. The ergonomic point of view, such a system offers significant improvements in employees' working conditions and despite these improvements are significant, we can still identify ergonomic problems related to the activities of workers. In this context, this work aims, through ergonomic work analysis - AET, to survey the critical activities performed during the construction process and a diagnosis of the situations encountered on site. This research is exploratory to be keen to discover and observe phenomena, trying to describe them, classify them and interpret them and their driving was used as a research method, the case study. To capture the data, makes use of ergonomic analysis of manual work - EWA (Ergonomic Workplace Analysis), METs (The standard metabolic equivalent) and OCRA (Occupational repetitive actions) in which the following items were considered: Load-lifting, accident risk, attention, general physical activity, working postures and movements and repetitiveness of the work. Among the main findings stand out: the high risk of this accident carrying out the work due to organizational process of the company, moderate caloric expenditure in the execution of activities and high IE OCRA present in fixing activities (screwing) the structures and the sealing elements.

The dietitian is a generalist professional, acting in all areas of knowledge that food and nutrition are critical to the promotion, maintenance and recovery of health and prevention of diseases of individuals or population groups. According to the National Curriculum Guidelines (DCN – Diretrizes Curriculares Nacionais), you must allow that the proposed curricula are able to develop academic and professional profile with competencies, skills and content, relevant and consistent with national approaches to ensure the performance quality, efficiency and resoluteness, at the National Health System (SUS – Sistema Único de Saúde). This study aimed to analyze the dietitian’ professional formation, in the perspective of their performance in the National Health System. This research has a qualitative nature and the study population consists of the coordinators of nutrition courses in the universities of the State of São Paulo, whose courses have begun before 1988. This study was conducted in two stages: data collection through documentary analysis of the DCNs and the Courses Pedagogical Projects (PPC – Projetos Pedagógicos de Cursos), through a matrix of analytical categories, and semi-structured interviews with the coordinators of the nutrition courses. The interviews were composed by questions about the education of students to act in the SUS and issues relating the courses PPC with the DCN. The interviews were analyzed with the content analysis technique, thematic defined by Minayo. In compliance with the Resolution 466/2012 of the National Health Council, the research was approved by the Ethics Committee on Human Beings Research of the UFSCar and all individuals signed the Free and Informed Consentment Term (TCLE - Termo de Consentimento Livre e Esclarecido). From the nine Nutrition courses that suit to the study inclusion criteria, six courses made their PPC available. The analysis of PPC in the light of DCN demonstrated general suitability with some comments on the more traditional evaluation methods and greater emphasis to health care competencies in detriment to the competencies related to management and education. All PPC analyzed include the health needs and the formation of nutritionists emphasizing the SUS. The interviews were fundamental to verify, with the coordinator or their representatives, the challenges for the PPPs implementation in practice, such as : the involvement of the entire faculty, the organization of the course within the University, maintenance of program content within reduced workload and the qualification of teachers in Public Health Area. It was also identified gaps in the introduction of students and graduates in their actuation field in the SUS: lack of hiring of professionals involved in Health Network and deals with the city governments, as partners in the responsibility of training of professionals and implementation of PPC. It is clearly observed the importance of providing students with a curriculum that addresses the relationship between teaching-research-extension, in order to approximate the student to the job market. But this articulation does not occur effectively when we focus the SUS as acting field.

This work aims to study the relationship between the “teatro de revista” (revue) and the musical comedies made by Luiz de Barros. An important name in the history of Brazilian cinema, Luiz de Barros made dozens of films during his long career as a filmmaker. However, he did not dedicate his activities only to cinema, having established also an important career in "teatro de revista" and other stage shows. Based on researches in periodicals and archives, it was made a survey of the many activities of the director. Full of attractions, the musical comedies used elements of mass culture, like popular music and carnival, to attract the audience, bringing also several aspects of the “teatro de revista” and other artistic forms. Through the analysis of the movies Berlim na batucada (Luiz de Barros, 1944) e Caídos do céu (Luiz de Barros, 1946), this research aims to study how the filmmaker articulated characteristic elements of the “teatro de revista” in his films, both in the narrative level and in relation to production, also investigating the casting of theatrical actors and musicians well known to the public. Thus, this work intends to expand a research field of the history of Brazilian cinema that studies the dialogue with other kinds of entertainment.

This paper discusses the Federal Government Program “Minha Casa Minha Vida” and its implementation in Piracicaba from the perspective of its interaction with the social capital in the “lens” designed by Robert Putnam. In particular, it seeks to understand the actions or reactions of the major social actors resulting from the implementation of the Program, in its context, in Piracicaba. To this end, in addition to market analyzes and their trends about prices, it was identified the main elements of social capital in order to verify their relations with the applicability public policy at the local level. It was also and firstly assumed that real estate and construction companies, in Piracicaba, had a social organization tight enough to gain advantage in the market by overpricing houses or lands and raise funds or subsidies that would be allocated a priori for a program with social order, all disguised in a market logic that legitimate opportunistic actions. As it will be shown, however, the absence of social capital - as the engagement elements, civility and even problems in facing embedded cultural values - can be obstacles to the implementation of an effective policy in solving the problems related to the issue of social housing in the country. It will also be observed that the social organization of the business community, particularly in the real estate entrepreneurs in Piracicaba, do not have enough tight relationships and social organization to confirm the initial proposal that they could have some control on the market prices.

The mechanization of sugarcane harvesting in Brazil has been presenting significant growth since 2007. The machines used in the fields were originally designed in Australia and were transferred to Brazil in the 70 s. Since its original conception, the design has suffered several modifications and improvements. In ergonomics, it is known that the appropriation of artifacts leads to a process of construction and reconstruction of uses and devices, so that the design continues in usage. With this regard, the present study aimed to analyze the process of design in use of sugarcane harvester machines and to contribute to the understanding of how users design. Considering that the machine was originated in Australia, the study also aimed to conduct a comparative study between the two situations, based on the principles of antropotechnology. Furthermore, given the historical participation of users in design process of sugarcane harvesters, the study also aimed to verify whether this participation still exists now that the design is controlled by multi-national equipment manufacturers. For this purpose, three case study were conducted in Brazil and two in Australia, according to the principles of Ergonomic Work Analysis. The obtained results describe the studied situations, the activity and operation, the modifications in machine s design performed by the harvesting teams, the elaboration process and the need for design improvements. The modifications in machines design were divided into three categories: structural, functional and operational. Structural modifications aimed to adapt the technology to Brazilian conditions: the soil characteristics and the duration of the harvesting season in the country. Functional modifications aimed to solve design problems not anticipated by designers during design process. Operational modifications represented the contribution of users and their activity to the design. In Brazil, several modifications were found and they were elaborated through the articulation of competences of two actors: harvester operator and harvester mechanic. Besides the differences in the amount of modifications, other differences between the two countries were the work organization and the harvesting strategies. It can be concluded that: 1) design in use is essential to adapt a technology to local conditions of usage; 2) the genesis of instrumental genesis is in the junction of operators activity and of mechanics inventory to practice bricolage as a way of designing, as well as the existence of social spaces of interaction between these subjects; 3) users participation, which has always been essential to the design of sugarcane harvester machines, is still crucial and can be reached through a dialogical approach of design.

Investigations concerning pre-service teacher education in Chemistry have increasingly been made from the 1990s. Currently, studies that are based on reflective teaching are at the forefront. An alternative to creating a space for future teachers to reflect and discuss is setting up communities on the Internet using blogs. However, research aimed at using blogs in pre-service teacher education in chemistry in Brazil is scarce. In this work, we develop studies concerning the use of blogs in subjects related to the Curriculum stage and Teaching Practice in chemistry, taught on a long distance pre-service teacher education in chemistry. Therefore, we provide space on the blogs to publish and discuss activities carried out in lessons. Data was collected from publications on the blogs and by distributing questionnaires on the concept of teaching, as well as the use and acceptance of technology. We analysed the contributions of using blogs as a support tool for subjects, the evolution of the undergraduates’ teaching models and the perceptions of using blogs. We also detected and classified the levels of the undergraduates’ reflections concerning actions taken during the stages. Based on data analysis, changes from the future teachers’ previous conceptions could be observed regarding teaching and the acceptance of using blogs in education. Furthermore, using blogs helped the undergraduates to share, discuss and reflect on the activities of the subjects and actions taken in the curriculum stage. Finally, based on an extensive literature review carried out for this research and the results from it, we consider the benefits provided by the blogs in the context of pre-service teacher education, as well as the barriers that hinder its use.

The construction industry is the largest consumer of natural resources in their activities. It is estimated that a square meter of construction of a building is consumed an average of one ton of materials, which explains the use of large amounts of cement, sand, gravel, and other inputs during its construction process. Furthermore, the construction is the industry which produces more waste. In Brazil, this situation is aggravated by the construction technology normally applied in new buildings, especially in works of social interest. In these projects, the traditional process of implementation combined with poor quality of production management favors large losses and physical resources waste, which ultimately generate huge amounts of construction waste (RCC) in the beds. For all these reasons, the diagnosis of RCC generation in housing projects of social interest is of great importance, since it can support management strategies of material consumption to reduce waste and costs. In this sense, this paper aims to study the generation of waste from the construction of a housing project of social interest in the city of Taquaritinga-SP, with special focus on the generation rate (kg / m²) of this type of venture. The methodology will be held bibliographical and documentary reviews of the object of study work, and methodologies used by other authors in previous studies to obtain the generation of RCC and their respective generation rate per square meter. It should be noted that in developed countries, this waste production indicator from new construction is around 50 kg / m2, well below the Brazilian indices that revolve around 150 kg / m2. This study showed the rate of 226,28kg / m², demonstrating that the enterprise is slightly above the Brazilian indices. With the completion of this research, we hope to obtain important results for the area of social housing, as the studies of RCC does not include rates for this type of residential development, unlike the indexes extracted in vertical buildings or even reform and demolitions.

Organizational Culture is a theme that has been gaining interest in the academic area and in business management, mostly since the 1980's. Organizational culture can be understood as a set of assumptions, values, and artifacts transmitted between its members, creating a meaning which defines a behavior pattern in an organization. This study aimed to analyze the alignment between cultural and work related values of potential employees in a Brazilian Financial Institution. It was relevant for the studied company to analyze the expectations of the new employees, since these expectations may or may not converge with the present cultural values, influencing these people. Since the organizational culture rules the company and its member's behaviors, according to the definition, it is believed that the analysis of the alignment between work related values and the organizational culture is an important diagnostic tool for strategic actions. The research was developed in a large financial institution, of mixed economy, and because of this fact, it shows the coexistence between public and private values. By performing a survey between the potential employees of that organization (approved in a public examination and summoned to take office), it was possible to identify the values that would orientate their work life and, afterwards, these values were compared to the cultural values already existing in the company. With regard to corporate values (declared by the organization), an alignment in the ones related to safety, accomplishment, universalism, and benevolence was observed. As far as organizational values go (values shared by the organization members), there was an alignment in those related to safety, conformity, and self-determination, as well as a partial alignment in the values related to realization, universalism, and benevolence. Considering both types of values as representatives of the company's organizational culture, we found an alignment in safety values and a misalignment in the values related to power, dominance, and prestige. The lack of alignment in these values must be observed by the company, since that can influence the satisfaction of new employees with their work negatively, contribute to a higher turnover rate, and even influence the financial performance of the company. Additionally, the new employees values can, over time, modify the company's culture itself.

Penaeidae family occurs in all oceans, particularly in tropical regions and represents an important global fishing resource. In Brazil, penaeid species have been shown decline, of their populations, which are considered overexploited. Therefore, a greater knowledge about these species is required for the developing of appropriate conservation actions. However, genetic studies of penaeids, including phylogeography, geographic distribution and phylogeny, are still scarce. In the present work, genetic structure and genetic relationships were characterized for different marine shrimp species belonging to the Penaeidae family, with special emphasis on those of occurrence in the Brazilian coast (Xiphopenaeus kroyeri, Farfantepenaeus paulensis, Farfantepenaeus subtilis and Farfantepenaeus brasiliensis). Mitochondrial and nuclear markers were used in order to clarify aspects related to the geographic distribution and genetic relationships among the studied penaeid species and the implications for conservationist approaches. Specific oligonucleotides were designed to amplify four mtDNA regions (COI, 16S, Cytb and DLoop). The results showed efficient patterns for 16 native species of Brazilian and Mozambican coasts. Numts presence and its implication for penaeid genetics were investigated using specific and universal primers for COI gene. Pseudogenes were detected for some penaeid species. Cytb pseudogene for the Penaeidae family was reported by the first time. DNA barcoding approach was tested in several species from Brazilian coast. The barcoding analysis evidenced a high range of intraspecific distance, suggesting the necessity of taxonomic review into Penaeidae. The existence of species complex was investigated for both X. kroyeri and F. subtilis. Phylogeographical signs and population structure were no observed for F. subtilis along the Brazilian coast. F. paulensis populations, collected in Lagoa dos Patos (RS) and Cananéia (SP), showed genetic structuring by analyzing of COI gene. That data can be reflecting the existence of differentiated-genetically adult stocks or ancient structure. Two recent population expansions, one of them before and the other one after the last period of the maximum glacial, were observed for F. paulensis. mtDNA and RAD-seq data were using to study the species X. kroyeri populations. The mtDNA analysis suggested that the upwelling from Cabo Frio (RJ) consists in a semipermeable barrier to X. kroyeri species, limiting the genetic flow between populations from North and South of Cabo Frio for. The analysis of approximately three thousand SNPs revealed three different genetic stocks, possibly related to the hydrodynamic characteristics of the sampled geographic regions, which may be holding different larvae pools. The study herein brings important information about genetic relationships and population structure for Penaeidae species, mainly those species occurring in Brazil. Such data can be help to foment future actions aiming the conservation of penaeid species, which present ecological and socioeconomic relevance.

The main objective of this work is to make students understand the mathematical foundations for the operation of Global Positioning System (GPS). The research was done in a school in the state of São Paulo with students of the second year of high school and the analysis was done in a qualitative as well as quantitative manner. Two sheets of directed activities, were used so students were induced to understand what happens at the intersection of spherical surfaces and this was carried out in three stages. During the first activity, students reviewed the circles of intersection of ideas, both geometrically and algebraically. In the second activity, these ideas were enlarged to spheres. The operation of the GPS was exposed in the activity three using PowerPoint slides, so goal that students learned a little about the history of the GPS creation and its operation, and the central theorem of this work: "If four spherical surfaces intersect and their centers are not coplanar, then this intersection is a single point." The Didactic Engineering was the methodology used for the survey. The result indicates that although many students present difficulties during the activities, everyone understood the mathematical principles behind the GPS operation.

Cryptography is a fascinating topic, concerning the practical point of view, and it is useful to access bank accounts, e-mails and social networks. According to this perspective, this study aimed to show how simple it may be to make use of cryptography. It was proved, through the work performed, that it is possible for students from elementary and high school to encrypt and decrypt messages using R.S.A. Cryptography, which involves the concept of creating public keys and private keys for the encryption of messages. A simple but powerful activity on the utility view was assigned to show students from the 9th grade of elementary school and from the 1st and 2nd years of high school from a private school in São Paulo State how interesting and pleasurable the use of Mathematics can be. Such activities are not usually present in the traditional didactic materials. The theoretical tools, containing theorem and corollaries, as well as their demonstrations, which mathematically justify the validity of techniques and the algorithm used on R.S.A. Cryptography will be presented. The activities do not assume sophisticated prerequisites and can be applied in the classroom, in real situations, so that the students can appreciate the beauty of Mathematics.

This work has as its theme the Politics of Science and Technology focusing on the city of São Carlos in the State of São Paulo. From a theoretical development of Science and Technology Policy in general in Brazil and locally analyze the case of San Carlos taking as its starting point the perspective of the Science and Technology for Social Development. Highlighting various information of socioeconomic and scientific-technical policy of the municipality, two objects of research, the Technology Park of San Carlos (ParqTec) and the Municipal Sustainable Development, Science and Technology, representing the Municipality, were studied in search up which elements contribute or not to social development. From this study we show that San Carlos is the technological center model because of the multiplicity of actions and institutions with innovative potential, but needs to consolidate to fulfill this role as a development model locally, and a C & T for social development.

In this study, samples of coprolites (fossilized feces) were analyzed in LIBS (Laser-Induced Breakdown Spectroscopy) to evaluate the chemical profile in these samples using hyperspectral images, which enable us to assess the different concentration of several elements in the same image. One of these samples was submitted to analysis by ICP OES (Inductively Coupled Plasma Optical Emission Spectroscopy) separately (rock and coprolites) to assess the actual concentration of each element in both of the arrays. Through the results of both techniques, it was possible to infer the diet of animals that generated the coprolites. The samples correspond to the Oligo-Miocene, Cretaceous, and Permian periods (28, 85 and 260 million years, respectively). Coprolites samples showed positive correlation between the Ca and P elements, indicating the presence of Ca3(PO4)2, compound generally present in carnivorous animal waste. In rock samples, the predominant elements were Al, K, Na and Si. Through a PCA analysis (Principal Component Analysis), it was found that the elements that characterized the samples changed as the age. Through scores graph analysis, it is possible to identify groups of samples in chronological order. The soil samples were analyzed by NIRS (Near-Infrared Spectroscopy) in an attempt to create classification models for soil texture, which is characterized by sand fractions, clay and silt soil. These are differentiated by particle size. Various strategies have been adopted in an attempt to improve the created models and several chemometric tools were utilized, such as SIMCA, KNN and PLS-DA for classification, giving satisfactory results as accuracy 83-100% for the calibration set. PLS to quantify the levels was also tested, but without success. The samples were also subjected to analysis by LIBS and soil encapsulation strategy with a polymer was tested, also without success, since the LIBS generates the spectral profile elements and does not distinguish particle size.

This work handles topics involving geometric transformations and friezes for the study of symmetry. It aimed to present students from the Ninth Grade of a public school in São Paulo State activities, in order to enrich them scientifically, culturally; sharpening their curiosity and critical reasoning. For this, a series of activities related to the theme symmetry was developed: first of all, students solved questions on a diagnosing sheet of paper about translation, reflection and rotation movements on the plan, followed by a slide presentation of these same topics. Then, they watched a video about Alhambra Palace in Spain to motivate them to study the symmetries in decorative friezes. Students solved various problems of OBMEP involving symmetrical situations and they ended up the work building seven patterns of friezes. The analysis of these solutions is presented in order to verify whether there was a contribution to the learning of geometric transformations related to symmetries. Such analysis is based on the researcher’s experience and also on testimonials from the participants.

Millions of surgeries for implants and prosthesis placement are performed annually worldwide. Among these surgical procedures are observed some types of failures. The most worrying complication is the infection that can cause deformity in the region, amputation of body parts, and may progress to osteomyelitis and patient death. In this context, the bactericidal property of the bioactive glasses is being widely studied. The F18 is a new bioglass that was developed at Vitreous Materials Laboratory (LaMaV) and can be manipulated in different forms to be used as auxiliary agent in the medical treatment of infectious processes. The purpose of this study was to investigate the bactericidal activity of F18 in powder form for coating implants and in fibers form to be used in wound healing, on the bacteria Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. In addition, it was proposed to compare the kinetic of bactericidal activity of F18 in powder, F18 in powder doped with silver (F18Ag), and the standard bioglass called 45S5, on S. aureus. The bactericidal activity of F18 was tested using an analysis method based on a standard JIS (Japanese Industrial Standard) Z2801: 2010, where the inoculum was in contact with the material for 24 hours and the reduction of viable cells was observed after this period. For the realization of kinetic tests the powder samples from different materials were placed in contact with the S. aureus suspension and an aliquot of these mixtures was plated in a culture media at different times. The direct count of colony on Petri dishes demonstrated the viable cells reduction. F18 both in powder form and in the form of fibers showed an extremely efficient bactericidal activity. The elimination of the microorganisms was close to 100%. The log of reduction of bacteria was between 5.9 ± 0.4 and 7.0 ± 0.2 log10 CFU ml-1, and the standard considers as a bactericide the material that shows a reduction of 2.0 logs or more. The bactericidal activity of F18Ag began after the first 30 minutes of contact with microorganisms and practically eliminated the bacterial colonies after one hour of contact. The bactericidal action of F18 started after six hours and eliminated viable cells after 24 hours. Both materials demonstrated bactericidal action similar to that presented by the standard 45S5.
