Muitas histórias, uma imagem: a percepção sócio-ambiental de alunos residentes da Escola Agrícola de Jundiaí

Tendo como base os conceitos de espaço, lugar, ambiente e imagem, sob as vertentes da Arquitetura e Urbanismo, Geografia e Psicologia Ambiental, esta pesquisa teve como objetivo averiguar a percepção de estudantes da Escola Agrícola de Jundiaí (EAJ UFRN) a fim de identificar aspectos das interrelações pessoa-ambiente que diferenciam tal escola de outras instituições. A coleta de dados utilizou multimétodos e investigou um grupo de alunos residentes na Escola que cursavam o ensino médio e técnico em agropecuária em 2006, analisando seus discursos, comportamentos e atitudes de modo a identificar os principais elementos da imagem sócio-ambiental da EAJ. Os resultados apontaram locais, práticas sociais e símbolos representativos da instituição, indicando espaços (construídos e naturais) adequados/inadequados às necessidades/expectativas dos estudantes incluindo a ampliação da interdisciplinaridade no conjunto de suas atividades. Além disso, a fim de incrementar a análise sócio-ambiental em instituições que promovem experiências exitosas, recomenda-se que os aspectos cotidiano e tempo sejam mais profundamente investigados em estudos futuros na área

Emprego dos ácidos graxos de cadeia curta na colite de derivação fecal : estudo em ratos Wistar

Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, after a colostomy. It is postulated that nutritional deficiency of the colonic epithelium by the absence of short-chain fatty acids (SCFA) is one of the factors responsible for the appearance of DC and that their employment could reverse the morphological changes of the mucosa. The treatment of choice for fecal diversion colitis (DC) is the reconstruction of the intestinal tract, although they suggested therapeutic options using enemas. This study evaluates the effect of SCFA in atrophy and inflammation in excluded colonic segments before and after the installation DC. Forty Wistar rats were divided into four groups (n = 10 for each group), submitted colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after postoperative day 40), for 07 days. Histological sections stained with HE were used for histological analysis of the thickness of the colonic mucosa excluded (t- Student p ≤0.05). Inflammatory reaction of the lamina propria and mucosa were measured with scores previously established (Mann Whitney p ≤ 0.05). There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 did not prevent the mucosal atrophy and significant increases in the numbers of lymphocytes (p=0.0006) and 50 eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

Emprego da citometria de fluxo na avaliação do perfil imunofenotípico de pacientes com leucemia linfocítica crônica

Chronic lymphocytic leukemia (B-CLL) is a clonal proliferation of mature B lymphocytes characterized by indolent clinical course. Biologically this clonallity is characterized by low expression of surface immunoglobulin (sIg) with restriction to a single immunoglobulin light chain associated with high expression of CD5 antigen and positivity to B cell antigens lymphocytes such as CD19, CD20 and CD23 and negativity to FMC7. The immunological profile and morphological analysis of lymphoid cells are the main means for the differential diagnosis of B-CLL from other chronic lymphoproliferative diseases. The aim of this study was to evaluate the expression pattern of a variety of membrane antigens in leukemic cells originating from patients with B-CLL. In this study, peripheral blood samples from 80 patients with B-CLL were analyzed by multiparametric flow cytometry in addition to routine hematologic exams, using a panel of monoclonal antibodies (MoAb): CD45/CD14, CD3/CD19/CD45, CD4/CD8 / CD3, CD20/CD5/CD3, CD3/CD16-56/CD45, CD2/CD7, FMC7/CD23, CD103/CD22/CD20, HLADR/CD38, CD10/CD19, CD1a, CD11b and also IgM/gD, kappa and lambda immunoglobulin light chains for the detection of surface immunoglobulin and clonal restriction for immunoglobulin light chain. The Hematological data were obtained from the hematological analyzer and cytomorphological analysis in blood film stained by Leishmann. The study samples consisted of 45 men and 35 women, ages ranging from 55 to 84 years (mean 65 years). Complete white blood count showed count ranging from 10.0 to 42.0 x 109/l. (mean 50.0 x 109/l) and lymphocytes count greater than 5.0 x 109/l in all cases. The neoplastic cells displayed B-CLL phenotype (CD5+/CD19+/CD20+/HLADR+/CD23+) in the vast majority of the cases, associated to failed to stain for T cell markers (CD1a, CD2, CD4, CD3, CD7, CD8), CD103, CD14 and FMC7. Leukemic cells of most patients also expressed low intensity of IgM and IgD with restricted kappa light chain, in most cases (59,7%). This observation highlights the importance of immunophenotyping for correct diagnosis of chronic lymphoproliferative syndromes and the panel of MoAb used was sufficient for diagnostic confirmation of B-CLL

Emprego de redes neurais artificiais supervisionadas e não supervisionadas no estudo de parâmetros reológicos de excipientes farmacêuticos sólidos

In this paper artificial neural network (ANN) based on supervised and unsupervised algorithms were investigated for use in the study of rheological parameters of solid pharmaceutical excipients, in order to develop computational tools for manufacturing solid dosage forms. Among four supervised neural networks investigated, the best learning performance was achieved by a feedfoward multilayer perceptron whose architectures was composed by eight neurons in the input layer, sixteen neurons in the hidden layer and one neuron in the output layer. Learning and predictive performance relative to repose angle was poor while to Carr index and Hausner ratio (CI and HR, respectively) showed very good fitting capacity and learning, therefore HR and CI were considered suitable descriptors for the next stage of development of supervised ANNs. Clustering capacity was evaluated for five unsupervised strategies. Network based on purely unsupervised competitive strategies, classic "Winner-Take-All", "Frequency-Sensitive Competitive Learning" and "Rival-Penalize Competitive Learning" (WTA, FSCL and RPCL, respectively) were able to perform clustering from database, however this classification was very poor, showing severe classification errors by grouping data with conflicting properties into the same cluster or even the same neuron. On the other hand it could not be established what was the criteria adopted by the neural network for those clustering. Self-Organizing Maps (SOM) and Neural Gas (NG) networks showed better clustering capacity. Both have recognized the two major groupings of data corresponding to lactose (LAC) and cellulose (CEL). However, SOM showed some errors in classify data from minority excipients, magnesium stearate (EMG) , talc (TLC) and attapulgite (ATP). NG network in turn performed a very consistent classification of data and solve the misclassification of SOM, being the most appropriate network for classifying data of the study. The use of NG network in pharmaceutical technology was still unpublished. NG therefore has great potential for use in the development of software for use in automated classification systems of pharmaceutical powders and as a new tool for mining and clustering data in drug development

Proteção da relação de emprego sob o prisma da dignidade da pessoa humana

This work aims to show that the protection of the employment relation is one of the determining factors to respect the principle of the human dignity. The goal is initially to show the devaluation of work from antiquity to the early twentieth century, when the constitutions began to standardize protective devices. This way, the consecration of the social labor rights in the Constitution of 1988 represents the culmination of the historical achievements. This work demonstrates that such rights can not be reduced or suppressed by political conveniences, once these rights are included in the list of immutable clauses. It is displayed that to achieve the fundamental right to work is not well advised to encourage the creation of jobs that maculates the worker s dignity. The outsourced work is, therefore, a classic example of the advancement of precarious forms of contemporary labor. It is inferred that the presence of various forms of harassment results in a degradation of working environment, bringing about dire consequences on professional and personal life of the worker. Thus, decent work must be the appropriate benchmark for the creation of new jobs. It is also shown that the flexibilization of the propaganda rights by certain pressure groups has as main goal to reduce or eliminate rights, based on fallacious data depicting an increase of competitiveness and jobs. In addition, the flexibility implies a growth of the precarization of the work - a reality felt by many workers subjected to such a situation due to the unemployment phenomenon whose origin is not in the protectionism of the norms. It is necessary to expand and structure the constitutionally legitimate institutions to monitor and curb the precarized work, as well as all practices that go against the dignity of the worker. It is also shown the loss of power of the sindicates in the last few years as a consequence of the pulverization workes and the capital attacks through the productive restructure whose outsourcings and privatizations are notorious examples

Emprego formal na região nordeste brasileira: seus efeitos na inclusão social

This work aims to study the problem of the formal job in the Brazilian Northeast region and its effect in the social inclusion, taking for base the analysis of variables defined in the Atlas of Social Exclusion, which is based on the 2000 Brazilian Census, choosing the county as unit of analysis. As methodological options, an exploratory data analysis was performed, followed by multivariate statistical techniques, such as weighted multiple regression analysis, cluster analysis and exploratory analysis of spatial data. The results pointed out to low rates of formal job for the active age population as well as low indexes of social inclusion in the Northeast region of Brazil. A strong association of the formal job with the indicators of social inclusion under investigation, was evidenced (schooling, inequality, poverty, youth and income form government transfers), as well as a strong association of the formal job with the new index of social inclusion (IIS), modified from the IES. At the Federative Units, in which better levels of formal job had been found, good indexes of social inclusion are also observed. Highlights for the state of the Rio Grande do Norte, with the best conditions of life, and for the states of the Maranhão and Piauí, with the worst conditions. The situation of the Northeast region, facing the indicators under study, is very precarious, claiming for the necessity of emphasizing programs and governmental actions, specially directed to the raise of formal job levels of the region, reflecting, thus, in improvements on the income inequality, as well as in the social inclusion of the population of Northeastern natives.

O emprego juvenil no limiar do século XXI :estudo a partir da RAIS e dos programas de inserção de jovens no mercado de trabalho de Natal/RN

This study received the title THE JUVENILE EMPLOYMENT IN THE THRESHOLD OF THE XXI CENTURY: study starting from RAIS and of the programs of youths' insert in the labor market of Natal/RN . It presents as main objective to investigate, starting from the officials data of the Ministério do trabalho e emprego - MTE and of the federal and state government programs, the evolution of the formal employment for youths and the difficulties that leads the success of the returned initiatives the youths' insert in the formal market of work in Brazil and in Rio Grande do Norte, in the period from 2000 to 2004. To accomplish the research, it prioritizes the study of the evolution of the formal employment starting from the data of the MTE as form of diagnosing the formal market of the juvenile work. Search a descriptive way to identify the first results of the programs Primeiro Emprego- PPE (federal) and Primeira Chance - PPC (state), to interpret and to identify the existent gaps among the proposal initial of those programs and the first results obtained in the city of Natal. The research has character no-probability and it applies closed questionnaires for youths assisted by the programs. Were interviewed the local representatives of PPE and PPC, besides representatives of the organized civil society all through open structured interview, covering a total of 103 interviews. The results demonstrated that while PPC (state) obtained success inserting youngs, the PPE (federal) just got to insert 1,5% of the amount subsidized by the state program in Natal. That situation demonstrates a clear preference of the companies for PPC (state), in detriment of the federal program

Podem os programas sociais e de transferência de renda influenciar a oferta de trabalho em atividades não agrícolas? uma análise para as famílias em condição de pobreza no meio rural do nordeste

This study aims to analyze the main effect of social programs and cash transfers on the labor supply of non-farm family members in poverty in rural areas of the Northeast. Among the specific objectives, we sought to investigate the effects of these programs and individual characteristics on the decision of participation and allocation of working hours of parents and children in non-agricultural activities. It was assumed, as a theoretical basis, the model of neoclassical labor supply as well as the principle that the decision of allocation of working hours, non-agricultural, is subject to the initial choice of the worker devote or not the non-agricultural employment . The hypothesis assumes that access to social programs and income transfer contributes to the dismay of rural workers, in poverty, in its decision to participate and offer hours of work in non-agricultural activities. To achieve this objective, we applied the models of Heckman (1979) and Double Hurdle, of Cragg (1971), consisting of associating the decision to participate in the labor market with the decision on the amount of hours allocated. The database used was the National Survey by Household Sampling (PNAD) of 2006. The results of the heads of households showed that transfers of income, although they may have some effect on labor supply rural nonfarm, the magnitude has to say that there may be some dependence on benefits. The estimates for the joint children of 10 to 15 years showed that the programs have negatively influenced participation in suggesting an increase in school participation, although for the allocation of working hours the results were not significant on the incidence of child labor

A evolução do emprego formal industrial nas cidades médias do estado do Ceará (Juazeiro do Norte, Crato e Sobral) no período de 1990 a 2010

The work consists in a discussion of the evolution of formal employment in the industrial cities of Ceará state averages from 1990 to 2010, since this period was marked by important changes. It is emphasized that in order to achieve this aim, the present study was based on a survey of relevant literature on the subject, as well as the use of the Annual Report of Social Information (RAIS), published by the Ministry of Labour and Employment (MTE) and the Brazilian Institute of Geography and Statistics (IBGE). The central question to be considered in this study is how we evolved formal employment industry in medium-sized cities (Juazeiro do Norte, Crato and Sobral) of Ceará? The assumption that guides this work is that given the economic policies of the 1990 and 2000 these policies encouraged the relocation, thus implying significant growth in the formal manufacturing employment in these cities. Regarding the results obtained in the survey, it was found that the industrial sector of these cities, showed considerable dynamism in what refers to the expansion of establishments. When observed in percentage terms medium-sized cities (345.5%) had the highest growth in number of establishments in the 1990s with rates higher than the Northeast region (285.9%) and Brazil (167.5%). The highlight was the city of Juazeiro, with the highest concentration of micro and small footwear companies in the state. Regarding the number of formal jobs created in medium-sized cities, it went from 6.596 in 1990 to 41.660 million formal jobs in 2010, with a growth rate of 532%. The sector contributed most to employment generation was the footwear. Although the levels of minimum wages, the 1990 recorded the lowest levels. In the 2000, there were real gains in levels of minimum wages in all cities, however, it may be noted that over the decades there has been significant momentum. However, this momentum was not enough to prevent the end of the study period CMs-Ceará present low wages

Industrialização e emprego formal: uma análise para os municípios da região metropolitana do Cariri nos anos de 1990 e 2000

The Northeast has a record of fighting to reduce disparities. In late 1950, the state intervened through SUDENE, organizing and planning the promotion of development through industrialization. This study aims to identify the characteristics of the industrialization of the Northeast and evolution of formal employment in the metropolitan area of Cariri, located in the southern state of Ceará, in the case of the municipalities of Crato, Juazeiro do Norte and Barbalha (CRAJUBAR) in decades of 1990 and 2000. The assumption permeates the SUDENE with public policies to encourage the industry, causing profound changes in the cities studied. The results indicate that the Cariri since the 1960 has been benefiting the programs implemented by SUDENE. With the implementation of these programs, with in a set of circumstances based on local vocations and state policies, there was a spatial distribution industry, triggering a growth and development on the provision of formal jobs in the industrial sector

Reconfigurações industriais das regiões metropolitanas do Nordeste: uma análise a partir do emprego formal

Industrial development experienced by Brazil from the 1950s, changed the concentration of population in the country. The process of development of domestic industry, concentrated in urban areas, crowded growing portion of the population.The Southeast region during the first stage of industrialization driven by the state, with the implementation of Plan goals, captained the major industrial projects implemented in the period and became the main industrial center of the country.In the decade from 1960 to 1980 the state action was marked by numerous regional development projects, softening the industrial concentration and Brazilian investment redirected to the Northeast.The second National Development Plan implemented in the 1970s led to major investments Northeast.This period marked the widespread urban growth and institutionalization of the first metropolitan areas in Brazil.The change of this developmental process is altered with the fiscal and financial crisis of the state in the 1980s and 1990s and spending cuts aimed at national development, reorienting the economy to liberal policies of economic liberalization and reduction of activity in the economy.Industrial policy was relegated to local development plans from the 1990s to the federating units fitting the wide use of tax incentives, the "war tax" to the continued industrialization process.In this context of the national economy work seeks to analyze the industrial setting in the metropolitan areas of Fortaleza, Recife and Salvador between 1995 and 2010.Although the metropolitan areas of Fortaleza, Recife and Salvador are the main urban centers of the Northeast, responsible for the advancement of industrial development, reconfigurations occurred between 1995 and 2010 by changing the level of industrial specialization built by regional division of labor in these regions.The work will be carried out by the method of descriptive analysis of the literature review on regional and urban development.Constitute quantitative method as the secondary data analysis of formal employment from the Annual Social Information (RAIS) Ministry of Labour and Employment (MTE).Using data RAIS / MTE analyzes the industrial specialization index using the Locational Quotient (LQ).Thus, it is assumed as a parameter analysis QL> 1, when the region has become specialized in a particular sector or QL <1, when the region does not have expertise in industrial sector analyzed.The conclusion of study indicates that there was in these metropolitan areas maintained the same bias hub.Fiscal policies, the states, was not successful in diversifying the productive structure and the Northeast region itself.This result is demonstrated by the need and dependence on state investments in the region to promote development.Industrial policies of recent years have been positive to meet the objectives of employment generation, but there must be specific policies for better diversification of production, in addition to integrating the economy of the Northeast sector and regionally

Fatores que afetam a competitividade na produção de hortaliças orgânicas no Estado do Rio Grande do Norte

The Brazilian organic market has growing year by year, and this commercialization is extremely important to the country, because it allows a bigger preoccupation with the environmental preservation, as well as to create employments and income to the rural workers. However, is necessary that these producers define forms of competition in the market, the way how they will compete, focusing aspects that really matters to the clients. So, the work objective is investigate, based in the rural producers perceptions, the facts which affect the competition the production of organics vegetables in the state of Rio Grande do Norte. With the aim of contribute to the made of strategic decisions related to the production and commercialization of these products in the agriculture scenery norte-rio-grandense, besides to contribute with information about the competition, helping as reference to others important researches. In the methodological view, this study can be qualified as an applied research study, with descriptive objective and quantitative approach. The instrument used was the formulary, resuming to producers of organics products in Rio Grande do Norte state, that grows the segment of organic types of vegetables and greens, been thirty two producers. The data was treated through of the descriptive analyze and the Cluster s analyze. The descriptive research results indicate that the main factors which affect the competition of the organics products in our State are the cost, the diversification and reliability. The Cluster s analyze shows that exists am group of organics producers who uses frequently a specialized technique and they give support to the bigger retail market, as supermarkets

A gestão da qualidade nos cursos de graduação a distância da UFRN/SEDIS : a percepção dos discentes

The management of water resources in the river basin level, as it defines the Law nº 9433/97, requires the effective knowledge of the processes of hydrological basin, resulting from studies based on consistent series of hydrological data that reflect the characteristics of the basin. In this context, the objective of this work was to develop the modeling of catchment basin of the river Jundiaí - RN and carry out the study of attenuation of a flood of the dam Tabatinga, by means of a monitoring project of hydrological data and climatology of the basin, with a view to promoting the development of research activities by applying methodologies unified and appropriate for the assessment of hydrological studies in the transition region of the semiarid and the forest zone on the coast of Rio Grande do Norte. For the study of the hydrological characteristics of the basin was conducted the automatic design of the basin of the river Jundiaí, with the aid of programs of geoprocessing, was adopted a hydrological model daily, the NRCS, which is a model determined and concentrated. For the use of this model was necessary to determine some parameters that are used in this model, as the Curve Number. Having in mind that this is the first study that is being conducted in the basin with the employment of this model, it was made sensitivity analysis of the results of this model from the adoption of different values of CN, situated within a range appropriate to the conditions of use, occupation and the nature of the soil of this basin. As the objective of this study was also developing a simulation model of the operation of the Tabatinga dam and with this flood control caused in the city of Macaíba, it was developed a mathematical model of fluid balance, developed to be used in Microsoft Excel. The simulation was conducted in two phases: the first step was promoted the water balance daily that allowed the analysis of the sensitivity of the model in relation to the volume of waiting, as well as the determination of the period of greatest discharges daily averages. From this point, it was assumed for the second stage, which was in the determination of the hydrograph of discharges effluent slots, that was determined by means of the fluid balance time, on the basis of the discharges effluents generated by a mathematical equation whose parameters were adjusted according to the hydrograph daily. Through the analyzes it was realized that the dam Tabatinga only has how to carry out the attenuation of floods through the regularization of the volume of waiting, with this there is a loss of approximately 56.5% on storage capacity of this dam, because for causing the attenuation effect of filled the shell of this dam has to remain more than 5m below the level of the sill, representing at least 50.582.927m3. The results obtained with the modeling represents a first step in the direction of improving the level of hydrological information about the behavior of the basins of the semiarid. In order to monitor quantitatively the hydrographic basin of the river Jundiaí will be necessary to install a rain gauge register, next to the Tabatinga dam and a pressure transducer, for regular measurements of flow in the reservoir of the dam. The climatological data will be collected in full automatic weather station installed in Agricultural School Jundiaí
