    The present study is linked to the Postgraduate Program in Education of UFSCar, under the research line Theories and Practice in School Education. The central theme of this study is the Theatre and Education. The object of the study has as references Theatre of the Oppressed’s working techniques, a theatrical teaching methodology created by Augusto Boal, who seeks to identify the injustices established in oppressed-oppressor’s relations and overcome them through Concrete and Continued Social Actions. Since it is a Library imprint of research, we look for material at dissertation’s bank and Capes’s Theses, who fieldworks were conducted in formal and non-formal learning environments who practices the Theater of the Oppressed methodology. We investigated these theses and dissertations understand the interpretation and the use they make of the Oppressed Theatre. We grouped the works in two (02) themes; School Education (representing formal learning environments) and Social Education Processes (representing informal learning environments). For the development of this research we used the content analysis technique, beyond the presentation of quantitative and qualitative data of theses and dissertations.

    Brazil is the world’s second largest producer and exporter of bovine fresh meat, what in 2014 accounted for about US$23.31 billion in Gross Value of Production (GVP) in a market of US$62.97 billion per year, generating about 7 million jobs. The most evaluated parameters about meat, can be divided into physical-chemical like temperature (T), water activity (Aw), redox potential (Eh), hydrogen ion potential (pH), maturation or tenderization, cooking method and sensorial like color, softness, texture, juiciness and flavor - combination of aroma and taste. As 75% of muscle composition is water, in the muscle conversion into meat there is a release of 2 to 5% of this total water, due evaporation and exudation, characterizing a high Aw value. This obtained solution is rich in amino acids, peptides, nucleotides, sugars and although the vacuum packaging is considered an efficient way to preserve in natura chilled beef, a serious problem, known as blown pack may occur if microbial contamination is significant or not respect the cooling minimum temperature (4 ± 2 °C). Therefore, the reduction of microbial proliferation in food is necessary. The goal of this work was to use a coating based on chitosan at 1% (w/w) and glycerol at 0.5% (w/w) which can be applied to food protection, especially as edible films and coatings. In parallel, was evaluated the effects of extract (PEE) and propolis nanoparticles (PNs) on some bacterial genders commonly found in fresh meat in natura. The permeability of the film produced in this work, respectively to O2 and CO2 gases was 1.53 ± 0.73 • 10-15 g•m•(Pa•s•m2) -1 and 1.20 ± 0.06 • 10-12 g•m•(Pa•s•m2) -1, relatively larger, when compared to literature. This film has relatively high moisture content and low solubility, what is interesting for application in meat, because it keeps its barrier property and integrity, even under high humidity and possible high Aw. Regarding the color (Hue) of meat samples (Longissimus dorsi) used in this experiments, on the 7th day presented a small disadvantage of coated and vacuum samples relative to that were not vacuum. However, on the 14th day, brightness (Chroma) of the samples in this condition was better than the other samples and, there was no significant difference in color. Therefore, this condition yet can be considered more advantageous when we wish to extend the shelf life time. The coating developed in this work, improved water holding capacity (WHC) of meat samples, which helps the desired juiciness of the product. Besides that, this film inhibits the growth of enterobacteria, lactic acid bacteria (LABs) and total psychrotrophic, which certainly can increase the shelf life of the product. The used PEE has a relatively high phenolic content and antioxidant capacity. For all tested concentrations of PEE and PNs with all bacterial species, better results were obtained with PNs.

    Brazil is characterized as an essentially urban country, because more than 80% of the population lives in cities. By the end of the 20 th century, the Brazilian cities, mainly the large and medium ones, started to face problems of difficult solution as a consequence of the overpopulation in the urban centers. Urban centers, which usually shelter the historical and cultural heritage of the city, in other words, its memory, today is constituted by run down areas, harboring slums, deteriorated buildings, decadent commerce, among other problems that intensify the deconstruction of this space. The Statute of the City serves to equip the municipal districts, so that these can develop and execute their urban policies assuring the right to the sustainable city, which involves, among others, the protection, preservation and recovery of the environment as well as of the historical, cultural and landscape heritage. The present study analyzes how the partnership involving the government, the private sector and the estate owners, interacting with each other, destined for the users and the community, can revert the process of degradation of the historical centers through the “Alegra Centro” program, currently on the way in the city of Santos. This study can still be a contribution to revitalization programs of port areas.

    This study aimed to contribute to the understanding of the dynamics of water resources in the watershed of Sorocaba river and establish relationships between availability and water demand. Initially it was proposed a quantitative model of how to distribute the water in the different stages of the water cycle, from the moment of the rains, to flow to your river mouth, considering the intermediate steps between these two events, including human interventions represented by withdrawals of water from springs. For it was carried out the survey and analysis of hydrological data available and estimated those without measurements through the water balance. Set up for the series evaluated the climatological normal temperatures and rainfall and the average flow rate in river mouth, ie the watercourse that is base level of the watershed. The following parameters were estimated: potential and real evapotranspiration, surplus and water deficit. The average rainfall in the basin for the period 2006-2012 was 1,337 mm.year-1 , the average annual temperature 21.2°C, the ETP and ETR 1,011 mm.year-1 and 999 mm.year-1 , respectively, the water surplus 338 mm.year-1 , the average flow in river mouth 360 mm.year-1 and the flow derived and actually consumed by the users of 16 mm.year-1 . The water availability was adopted as the flow with 95% permanence (Q95%), estimated at 24.1 m3 .s-1 and the demands were obtained based on data from granting processes and by other methodologies, enabling a comparison between the results. Demands for major consumptive uses identified in the watershed were calculated with the following results: human supply 6.20 m 3 .s-1 ; industrial 1.83 m 3 .s-1 ; irrigation 3.59 m 3 .s-1 ; and animal consumption 0.24 m 3 .s-1 . The relationship between availability versus demand was considered and the results allowed indicate that the current situation of water resources across its use is very critical.

    This research, elaborated from theoretical grounds in the area of design and ergonomics, has as its object of study an improvement project implemented in a producer of cellulosic fiber packaging (molded pulp) for packaging eggs and fruit, located inside the State of São Paulo. This project aimed to improve the operation conditions of the workers who took care of finishing activities at the apple trays production line. The research question is to discuss how the use of the Ergonomics concepts in the development of workspace design projects can help to prevent against new constrains on the development of activities. Specifically, it seeks to highlight the need of using tools that provide to the design process deep details about the activities involved in carrying out the tasks of the workspace where the improvement project will be implemented. Considering that the Ergonomics in workspace design can contribute for the collective construction to solve problems related to work reducing the probability of new constraints following the implementation of the project. It was used the approach of Situated Ergonomics, the Future of Activity Analysis and the method of Ergonomic Work Analysis. The obtained results showed that the design process used was not built with the effective participation of the users and the interaction between the actors involved in the operation lacked from an important knowledge about “how to do” of the operation. It was observed that the new situation brought difficulties in the development of activity as well as the creation of new constrains. It was concluded that the Ergonomics applied in the development of projects promotes the collective construction between the different actors in the process, resulting in a deep detail of the activities involved to develop the tasks and, as a consequence, better information being possible to design systems that meet the workers needs.

    How a brazilian viola come to its existence inside an artisan and manufacture environment? The materials allocated in such environment of craft arrange under specific conditions variable routes for one task: the precise and risky establishment of material compatibility degrees in each technical circumstance. When contouring the artisan and manufacture environment the object viola refracts the discourses about its existence in favor of the resources which assure its well defined boundaries. Whatever the discourses about the web-frames of that craft surrounding, it is through its functional inboard where the technical activity exposes its irreducibles: the technically articulated resources. A craft environment from Sao Paulo’s countryside thus assign to this research a problem of Comparative Technology, limiting this research to a focal descriptive procedure as a methodological experiment guided by rhytms of construction and repair of brazilian violas inside the craft environment – as far stand its instruments, tools, machinery and products. The frame of this Comparative Technology study is the processes of internal compatibility of a craft environment: the object viola is a process, a topical serie able to reconfiguration.

    The research is linked with the Education StrictuSensu Post-Graduation Program of UFSCar – Sorocaba and started with the participation in a group of homosexual/transgenderparents that used to arrange meetings of mutual help to fight against homophobia in the family context, the GPH, that has been established as a public policy in Sorocaba-SP since April/2013. The investigation was takento find out the limits and possibilities of this homophobia combat space through the presentation and analysis of categories and social conventions that merge there. From the theoretical field of gender and post-structuralistsexuality, it was sought to investigate the relations between families and homosexual/transgender, particularly the lives of the parents with the objective of comprehending and integrating their children. Because learning and investigating this relationship space is a process that cannot be measured to quantifiable variables, this research is qualitative. The methodological work was accomplished through the bibliographical research of documents and field studies, using the following procedures: documental analysis, interviews, prioritizing the participating observation and speech quantitative analysis in the perspective of events that took place in the maternity. The most difficult elements of this journey is the binary speech inheritance – man/woman, male/female, straight/homo – produced and reproduced daily inside the homophobic speech as in those that in some way are favorable to gender diversity and sexual orientation. The difficulties felt and supposedly faced by the GPH parents and the categories and social conventions mobilized in this journey were considered to be linked to differences built – social and culturally – translated in power relationships that rank gender, rendering inferior all forms that do not correspond to the linearity of sex, gender, desire and sexual practice. The implementation and participation at the GPH Sorocaba shown, not only the strength of heteronormativity, but also that the different fugitive form of being and living the genders and sexualities, generally not accepted but tolerated, highlighting that there is no social convention detachment in this context. At the same time, the attribution of new senses, the questioning of built “truths” that, for a long time, were naturalized and reproduced by these LGBT parents shows that public policies aimed to homophobic confrontation in family context have an important role to mitigate it.

    Green Photochemistry: Development of transition metal complexes for activation of luminescent singlet oxygen and its application in the disinfection of wastewaters contaminated with pathogenic microorganisms (Escherichia coli and Enterococcus faecalis). The development of the perylenes derivatives complexes Ru (II) and Re (I) has received increasing attention in energy transfer. Here in we investigated, the synthesis, characterization, energy transfer studies and biological testing of three complexes of Ru (II) and Re (I) cis-RuCl2(PDI1)2, cis-RuCl2(1,10- phen)(PDI1 ), fac-[Re(CO)3(PDI1)Br] and [Ru(1,10-phen)2(PDI2)]2+. The complexes are simple and stable preparation of both solid as well as DMSO solution (in the absence and presence of light) and are resistant to hydrolysis at pH 4 to 8. All compounds were characterized by 1H NMR, IV, elemental analysis and theoretical calculations whose results were consistent with the proposed structural. The complexes exhibit intense absorption in the visible region (500 nm, ε = 20,000 mol-1Lcm-1) and an intense band emission around 600nm, long emission lifetime 500 nsec and a small Stokes shift (600 cm-1), consistent with the rigid structure of the perylene chromophore. We observed that some complexes have paramagnetism ability in the ground state and both solution and on solid medium which was confirmed by RPE and theoretical calculation. These complexes were not able to produce photochemical 1O2. However, [Ru(1,10-phen)2(PDI2)]2+ presented photochemical generation of 1O2 dissolved in methanol, ethanol, acetone and acetonitrile and quantum yield of the formation of this species (Φ1O2) in order 0.30. Thus, we immobilize this complex on silica gel functionalized with aminopropyl group and it produced 1O2 with Φ1O2 around 0.20. The ability microbicide of these complexes were tested against the yeast Candida and values obtained show they are toxic for these microorganisms. These results lead us to believe that the complex can act on wastewater treatment.

    Agile development principles ensure that continuous attention to technical excellence combined with a good design contributes to increased agility ensuring products with higher quality. Usability is one of the quality attributes, and is related to making the experience enjoyable user through an efficient and intuitive interface design. Agile methods are committed to deliver valuable software to the satisfaction of the customer. At times, they deliver only the utility, without covering aspects of usability. Design solutions providing greater usability and more appropriate to the users’ context is the main concern of the Interaction Design (IxD). The IxD is based on user-centered design, which takes into account the users needs and wants, aiming to promote interaction more enjoyable experience. In recent years, the attention in integrating user-centered design practices into agile methodologies has increased. However, a very limited number of contributions have addressed the integration into a broader level, gathering practices and providing guidance to the organization of work within a software development roadmap. This dissertation presents an approach to integrate user interaction design into Scrum process through activities and artifacts. In the first stage of the study, a literature study was performed to determine possible strategies for integrating IxD into Scrum process. Furthermore, an action research approach was applied to define and evaluate the artifacts that would support the ScrumUX integration approach, closely with the professionals in the software development industry. In the second stage, an experimental study was carried out to evaluate the proposed ScrumUX integration compared to traditional Scrum approach. The experiment was carried out in an academic context, in which nineteen students divided into five teams worked in software development projects, in the ERP systems domain. Statistical tests confirmed a significant difference between the experimental and control groups, noting that the teams who used the ScrumUX approach produced software with better degree of usability in the task support perspective, considering ERP systems’ users opinion.

    Poly(vinyl alcohol) - PVA is a high hydrophilic semicrystalline polymer which has excellent properties such as good chemical resistance and high biodegradability and biocompatibility. Due to its semi-crystalline nature, crystalline domains, under controlled conditions, may act as physical crosslinking points, while maintaining the integrity of the structure under swelling. This feature makes PVA hydrogels promising for the development of drug, or other bioactive substances, delivery systems. Another interesting feature of this kind of hydrogels is the ability to form high stable network from crystalline domains formed through freezing and thawing cycles. This method shows the formation of crystallites which act as physical crosslinks while maintaining the insolubility of the material in water. Recently many studies show the use of nanostructures to improve mechanics properties and diffusional behavior of small molecules. Paromomycin is an aminoglycoside antibiotic widely used for cutaneous leishmaniasis therapeutics in Brazil. In the last years some studies have revealed that the patience adhesion to the treatments of cutaneous leishmaniasis with ointments form is low. Therefore hydrogels are an interesting alternative to the ointment forms. As the main objective of this work was the preparation and characterization of poly(vinyl alcohol) hydrogels containing sepiolite nanoparticles for the preliminary feasibility of using as controlled release system for paromomycin, hydrogels were prepared by cryogelation process. This ensures the formation of the hydrogel, as long as the crystalline domains formed during the PVA cycles act as crosslinking points, allowing the membranes water transport measurements of the drug in the presence of sepiolite. In this investigation membranes were characterized by differential calorimetry, thermogravimetry and X-ray diffraction. Furthermore polymer retention, swelling in simulated body fluid, hemocompatibility and drug delivery were studied to establish structure-properties correlations. The results show that cryogelation cycles significantly alter the swelling of the membranes; interactions polymer-nanoparticle increases the rigidity of the amorphous phase. Comparing to pure PVA hydrogels, in nanocomposites hydrogels the hemolysis decreased. Increasing the percentage of nanoparticles the membrane crystallinity decreases. The samples degradation profile, the thermal stability and drug delivery profile are not modified by the amount of nanoparticles incorporated.

    Automatic Multidocument Summarizarion (AMS) is a computational alternative to process the large quantity of information available online. In AMS, we try to automatically generate a single coherent and cohesive summary from a set of documents which have same subject, each these documents are originate from different sources. Furthermore, some methods of AMS select the most important information from the collection to compose the summary. The selection of main content sometimes requires the identification of redundancy, complementarity and contradiction, characterized by being the multidocument phenomena. The identification of complementarity, in particular, is relevant inasmuch as some information may be selected to the summary as a complement of another information that was already selected, ensuring more coherence and most informative. Some AMS methods to condense the content of the documents based on the identification of relations from the Cross-document Structure Theory (CST), which is established between sentences of different documents. These relationships (for example Historical background) capture the phenomenon of complementarity. Automatic detection of these relationships is often made based on lexical similarity between a pair of sentences, since research on AMS not count on studies that have characterized the phenomenon and show other relevant linguistic strategies to automatically detect the complementarity. In this work, we present the linguistic description of complementarity based on corpus. In addition, we elaborate the characteristics of this phenomenon in attributes that support the automatic identification. As a result, we obtained sets of rules that demonstrate the most relevant attributes for complementary CST relations (Historical background, Follow-up and Elaboration) and its types (temporal and timeless) complementarity. According this, we hope to contribute to the Descriptive Linguistics, with survey-based corpus of linguistic characteristics of this phenomenon, as of Automatic Processing of Natural Languages, by means of rules that can support the automatic identification of CST relations and types complementarity.

    Some conservation actions require the knowledge of the geographical distribution of species, however, this knowledge is far from being achieved for most species. The species distribution models (SDMs) have proved a useful tool to predict the distribution of species and guide field research to find new records. The SDMs using field data occurrence and environmental variables to indicate potential sites for the occurrence of a species. The quality and quantity of the data used are important to a successful result prediction models and application to conservation. The choice of environmental data and the algorithm and their settings are important for the development of models, the choice of these variables have directly influences to the quality of the models. Another very important step in modeling is the quality assessment and validation of the model, is that it may decrease the risk of accepting as true models with gross errors. The objective of this study is to evaluate the applicability of models generated by MaxEnt to find new populations of plants considering different data configurations used. For this, considering that the field validation is the most appropriate in the literature, but the most costly, the first chapter proposes a validation methodology of the models as easy application field. The methodology was able to find new records in the field, therefore, indicated for the validation of models. In the second chapter, knowing of the existence of a wide variety of variables that influence the performance of the models, the aim was to test the influence of the sample size, the spatial bias, the set of climate data and settings available for the MaxEnt algorithm in the areas of prediction potential distribution. The results demonstrated that the use of sampling and climate data restricted to the limit of the study area and also the use of soil data generate more accurate models.

    The popularization of mobile devices capable of communicating via wireless network technologies allows us to consider different scenarios in which these devices may autonomously interact with each other. The envisioned communications would occur in a P2P fashion, as each device could simultaneously provide and consume services. A mechanism for dynamically discovering nearby devices and the available services would be necessary. Although a few existing applications already provide the direct interaction among devices they are purpose-specific and rely on pre-configured information for identifying other devices. A service-oriented architecture (SOA), based on HTTP requests and the REST or SOAP protocols, is commonly used in this type of communication. However, automatically finding available known services is still challenging. Service discovery is usually based exclusively on service name, which is not very flexible. This work proposes a new model for the direct interaction between computing devices. In an attempt to facilitate service discovery and selection we propose a content centric model in which interactions are defined according to an object’s type and the action to be applied to it. The proposed approach can workatop of existing discovery protocols, based on extensible metadata fields and on existing service data. Our proposal is evaluated according to i) the viability of direct communication between nearby devices, even when carried by users or associated to vehicles; ii) the proposed service discovery and matching using the content centric approach; iii) the effectiveness of a middleware to support the development of generic applications for direct device communication. Simulation results show our proposed model is viable. A preliminary implementation of the middleware was also evaluated and the results show that spontaneous, opportunistic, service-based interactions among devices can be achieved for different types of services.

    The object of this work was to develop a panel about the installed institutional capacity in the municipalities of Ribeirão Bonito and Dourado – State of São Paulo, while characterized as small municipalities around an important country development center, the city of São Carlos. Therefore, it was made an analysis starting from the polysemic concept of Development, dissociating it from a mere economic growth, but adding to it the New-Developmentalism characteristics experienced in Brazil from the XXI century forth related to income distribution policies and popular empowerment. After that, it explains the difference between this phase and the nationaldevelopmentalism era of the second half of the XX century, when the logic of development was mostly an economic subject. Leather then go to an analysis of the characteristics of the state capacities required to this State in order to understand how this can promote the development of remote or small communities and devoid of endogenous possibilities for social transformation. It concludes with the presentation of a diagnosis of the State presence in these cities, in order to demonstrate how the regional public university, understood as an entity of the federal State, can contribute greatly to the training of agents of those communities in order to promote the development of their territories.

    In this work, a photometer/fluorometer micro-controlled (P2FM) multifunctional, portable, communicated by USB 2.0, robust, easy handling and with low consumption of energy was developed. The P2FM was built using a micro-controlled (PIC-18F2455) as central unit of process (CPU), two tricolors LEDs (470, 528, 621 nm) as source of radiation, a multichannel sensor (TCS3200) and the management program wrote in Visual Studio. One of the two LED was used as radiation source for photometric mode. The TCS-3200 is a multichannel sensor with four photosensitive tracks: 480, 540, 750 e 830 nm, being that selection of track is performed by program controlled. The management program operates sending functions for microcontroller, record of dates and storage of signal (*.txt) through of USB port 2.0 (5.0 VCC, 300 mA). The P2FM is compact, with 3.5 cm × 7.0 cm × 8.5 cm size and 159.4 g of weight, considered as a portable device. In the program is selected of function mode: photometer or fluorimeter. In the analytic performance test by photometric mode, were used three solutions amaranth (AM), blue light (AB) and tartrazine (TT). The detection limits obtained were 1.6 × 10−7, 5.4 × 10−7 e 1.9 × 10−6 mol L−1 for AM, AB and TT, respectively. The quantification limits obtained were 4.8 × 10−7, 1.6 × 10−6 e 5.9 × 10−6 mol L−1 for AM, AB and TT, respectively. The correlation coefficients were AM = 0.997, AB = 0.975 and TT = 0.994. The analytic performance for fluorometric mode was carried using in both fluorescein (FL) and Rodamine 6G (R6G) solutions, were obtained a detection limit of 8.3 × 10−8 and 4.79 × 10−8 mol L−1, respectively for FL and R6G. The correlations coefficients were 0.997 for FL and 0.999 for R6G. Also, the proposed device was successfully used to sulphite determination in drinks, total hardness in water, determination of stability constant and study of stoichiometry of a chromogenic complex, aiming to show any applications of photometer/fluorimeter. The constant of formation obtained was 5.04 × 1018 is concordant with that presented in previous reports 6.2 × 1018. In sulphite determinations on eight samples of drinks, the paired studen’s t-test showed that reference method and photometric method using P2FM was 0.66 times smaller than critic value (2.36, α = 0.05). The total hardness in water was determined by fluorometric method, being that the P2FM showed best sensibility 8.94 × 106 that a determination using the RF5301/PC spectrofluorometer. The paired studen’s t-test (α = 0.05) no showed significant differences, calculated t (0.36) small than tabulated t (2.01).

    A software concern may be defined as a set of requirements related to the same purpose. A CrossCutting Concern (CCC) (or Early-Aspect) is a concern whose requirements cutacross other concern requirements and the inadequate modularization of this type of concern may hinder the software development and evolution. The Aspect-Oriented Requirements Engineering (AORE) area provides more appropriate strategies for CCC identification, representation and composition. A commonly reported issue on AORE approaches is the low effectiveness provided by them, regarding to the concern identification and classification. This is due to two main causes: (i) the lack of a broader understanding about software concerns domain; and (ii) the lack of appropriate resources to support software engineers during the identification and classification of software concerns. This work aims to mitigate the reported issue by dealing with its main causes. To do this, we present: (i) a reference ontology for software concerns domain, called O4C (Ontology for Concerns), that aims to make clear and precise the description of the elements of this domain; (ii) an ontologically-based AORE approach, called ObasCId (Ontologically-based Concern Identification); and (iii) a computational tool, called OBasCId-Tool, that automates some activities of the ObasCId approach. The evaluation of the proposed approach and its computational support was carried out through experimental studies, in order to verify the effectiveness and efficiency of these research products regarding to concern identification and classification. The results indicate the ObasCId approach may contribute positively to the recall of software concerns without harming the precision and the execution time of the approach. Regarding to the ObasCId- Tool, it has been considered approved by its users, regarding to its usefulness and easeof- use features.

    The popularity of social networks have attracted attention of companies. The growing amount of connected users and messages posted per day make these environments fruitful to detect needs, tendencies, opinions, and other interesting information that can feed marketing and sales departments. However, the most social networks impose size limit to messages, which lead users to compact them by using abbreviations, slangs, and symbols. Recent works in literature have reported advances in minimizing the impact created by noisy messages in text categorization tasks by means of semantic dictionaries and ontology models. They are used to normalize and expand short and messy text messages before using them with a machine learning approach. In this way, we have proposed an ensemble of machine learning methods and natural language processing techniques to find the best way to combine text processing approaches with classification methods to automatically detect opinion in short english text messages. Our experiments were diligently designed to ensure statistically sound results, which indicate that the proposed system has achieved a performance higher than the individual established classifiers.

    Background: Shoulder impingement syndrome (SIS) is a common cause of shoulder pain complains and numerous treatment strategies are available in the clinic. Questions remain regarding the effects of Thoracic Spinal Manipulation (TSM) on SIS and concerning the efficacy of available techniques on the treatment of this population. Objectives: In a clinical trial, the objective was to evaluate short-term effects of a TSM on pain, function, scapular kinematics and scapular muscle activity in individuals with SIS. In a systematic review, the objective was to summarize current evidence regarding effectiveness of physical therapy to improve pain, function and range of motion in this population. Methods: In the clinical trial, participants were randomly allocated to TSM group (n=30) or sham-TSM group (n=31) and attended 2 intervention sessions over a 1-week period. Shoulder pain, shoulder function (DASH and WORC questionnaires), scapular kinematics and scapular muscle activity were measured. A blinded assessor evaluated the outcomes at day 1, day 2-pre, day 2-post and day 3. In the review, Pubmed, Web of Science, CINAHL Cochrane, Embase, Lilacs, Ibecs and Scielo databases were searched up to April 2015. Randomized controlled trials investigating different modalities of physical therapy in the treatment of patients with SIS on pain, function/disability or range of motion were included. Results: In the clinical trial, TSM group improved pain (1.1 points) and tended to improve function (5.0 points on WORC) over the sham-TSM group after 2 intervention sessions. Scapular upward rotation increased 4.0°, 5.3° and 3.3° at day 2-pre, day 2-post and day 3, respectively, in the TSM group during lowering of the arm. Changes in scapular internal rotation and tilt were not different between groups. Upper and lower trapezius activity decreased in the TSM group and both groups, respectively, during elevation and lowering of the arm. Serratus anterior activity increased in the sham-TSM group. In the review, sixty-two RCTs were included. The majority had a low to moderate risk of bias. Exercise therapy provided high evidence of improvements to the treatment in the short, mid or long-term. Dynamic humeral centering, proprioceptive exercises and manual therapy associated with conventional exercises enhance the improvements in the short-term. Low-level laser, ultrasound, pulsed electromagnetic field and kinesio taping provided moderate and high evidence level towards no benefits to the treatment of SIS. Microwave diathermy, transcutaneous electrical nerve stimulation and isolated manual therapy or acupuncture provided limited evidence of benefits. Conclusion: TSM may be worthy to achieve short-term reduction of shoulder pain, increase of scapular upward rotation and decrease of upper trapezius activity facilitating the application of other movement-based interventions in individuals with SIS. Exercise therapy should be used as the first choice to improve pain, function and range of motion, and the association of manual therapy should be the best choice to accelerate symptoms decrease and progress exercise therapy quickly. Low-level laser therapy, ultrasound, pulsed electromagnetic field and kinesio taping do not provide significant effects to the therapy and therefore could be avoided. More studies are necessary to improve evidence concerning effects of diacutaneous fibrolysis, microwave diathermy, transcutaneous electrical stimulation, acupuncture and isolated manual therapy techniques in the treatment of SIS.

    The aim of this work is to clarify the problematic relationship between subjectivity and transcendence in the Logical Investigations of Edmund Husserl. To this end, we draw a genesis of this problem, from the period prior of this work in question, until the end of his explicitness on Prolegomena. Such problematic relationship arises in Husserl combat against the psychologists conceptions of the end of sec. XIX, and, we sustain, is the biggest concern of this author throughout the course of the Investigations. What we will show in our work is how at the end of refutation of psychologism, is left to Husserl explain how can subjectivity and transcendence get in relation, since Prolegomena put such instances as separate natures, the legacy problem to the rest of the Investigations is to show how an act of judgment, which is a subjective experience, the subject enters into a relationship with the object judged by this act, the instance that transcends such subjectivity. The Husserl's answer is to present a discipline, phenomenology, which seeks to describe within the subjective, in the experiences of knowledge, the essence of the modes this subjective dimension refer to objects that transcend itself. We will explain how even after denying psychologist attempt, such a notion operates negatively throughout elaboration of the phenomenological method, that is, the phenomenology is as an overcoming of psychologism, in its most fundamental flaws.

    Electricity in Brazil is mostly generated by hydroelectric plants that depend on the volume of water in their reservoirs. Due to the fact that rainfall is decreasing, other methods with higher costs to generate energy are required. These costs are passed to users, increasing the energy bill. Futhermore, the wasting of energy and overconsumption also contribute to increase the energy bill. At the same time, the wasting of energy are not noticed by the user. To avoid such wasting, an alert could be sent as soon as an anomalous event is detected. In this way, we propose a system that sends an alert of any novelty detection in energy consumption through the analysis of the methods Sliding Window, Exponentially Weighted Moving Averages, Clustering, Average per Circle, Average per Stage, Gauss Distribution and Self-Organizing Novelty Detection. Results demonstrate that the methods evaluated are efficient in real time detection of novelties, presenting 90% of accuracy and 10% of recall, besides a low delay to send the alert.
