Benefícios e dificuldades na adoção de um sistema de gestão da qualidade no Rio Grande do Norte

Taking competitive advantage or satisfy the client are the reasons why companies have been implementing a Quality Management System (QMS). It brings benefits such as the improvement in the processes, products and services; an enhancement in the image of the company (marketing) and satisfaction of the clients. As a whole, this paper aims to evaluate the results obtained from the implementation of the QMS in the certified companies in the ISO 9001 standard, contained in the database of INMETRO, of the Rio Grande do Norte State (RN). In order to achieve the goals, a bibliographical research about the theme quality management system was made and, subsequently a survey was made with the managers of the certified companies in RN, using the online questionnaire. Out of 27 companies that have the certificate in Rio Grande do Norte, 21 responded the data collection instrument. The data analysis was made through techniques of descriptive and multivariate statistics: cluster analysis. The research instrument used contained 20 questions that address the main theme of this dissertation. Using the cluster analysis, four groupings that possessed similarities concerning the survey answers were found. This analysis allowed us to conclude that the QMS boosts significant improvements in the organizations, such as: quality in the reputation of the company and sales increase. On the other hand, it allowed us to identify as main difficulties: the dissemination of the quality culture, lack of commitment of the whole organization and the resistance of the workers

LDPE/EVA Composites for Antimicrobial Properties

Composites with antimicrobial activity are of great interest nowadays and the development of titanium dioxide with these functional properties presents interest in academic and industrial sectors.An approach to develop PE composite containing silver microparticles to have an antimicrobial effect is presented. To obtain such antimicrobial composites, LDPE/EVA were processed with Ag particles on TiO2 particles as inorganic carrier substance. Titanium dioxide nanoparticles (P-25) were covered with silver particles using Turkevich Method or citrate reduction method. The Ag/TiO2 particles were dispersed at concentration of 0,8 wt% and 1% wt% in LDPE/ethylene vinyl acetate copolymer (EVA)-(50% w/w) at the melt state in a Haake torque Rheometer. Silver microparticles were characterized with UV-Vis Spectroscopy. The composites thus prepared were characterized through XRD, Ares Rheometer, Scanning Electronic Microscopy (SEM) and JIS Z 2801 antimicrobial tests to study the effects of the addition of particles on rheological properties, morphological behavior and antimicrobial properties. The results showed that incorporation of silver/titanium dioxide particles on composites obtained systems with differents dispersions. The Ag/TiO2 particles showed uniform distribution of Ag on TiO2 particles as observed by SEM-EDX and antimicrobial tests according to JIS Z 2801 shows excellent antimicrobial properties.

Ionized-air-treated curaua fibers as reinforcement for phenolic matrices

Curaua fibers were treated with ionized air to improve the fiber/phenolic matrix adhesion.The treatment with ionized air did not change the thermal stability of the fibers. The impact strength increased with increase in the fiber treatment time. SEM micrographs of the fibers showed that the ionized air treatment led to separation of the fiber bundles. Treatment for 12 h also caused a partial degradation of the fibers, which prompted the matrix to transfer the load to a poorer reinforcing agent during impact, thereby decreasing the impact strength of the related composite. The composites reinforced with fibers treated with ionized air absorbed less water than those reinforced with untreated fibers.

Assessment of micronutrient extractants from soils of Paraná, Brazil

In Brazil, plant-available micronutrients in the soil can be determined by several chemical extractants, the most common of which are dilute acid and chelating solutions. The purpose of this study was to assess the extractants 0.1 mol L-1 HCl, Mehlich-1, Mehlich-3 and DTPA for analysis of the micronutrients Cu, Zn, Fe, and Mn in soils from the state of Parana. In samples from 12 soils (0-20 cm layer), wheat was planted (Triticum aestivum), grown for 42 days after emergence, and then bean (Phaseolus vulgaris) for 38 days. At the end of each planting period, the soil was sampled again. All extractants tested to assess the availability of Cu, Zn, Fe, and Mn correlated with each other. The efficiency of the extractants HCl, Mehlich-3 and DTPA in assessing plant-available Cu was similar, unlike Mehlich-1, which proved less efficient. The extractants HCl, Mehlich-1 and Mehlich-3 were less efficient in estimating plant-available Zn and Fe, and the most indicated extractant is DTPA. The efficiency of the extractants HCl, Mehlich-1, Mehlich-3 and DTPA in assessing plant-available Mn in soils from Parana was similar.

Extraction methods and availability of phosphorus for soybean in soils from Parana State, Brazil

In studies on the evaluation of methodologies for the analysis of soil, phosphorus (P) has been the single most studied aspect, due to the complexity of this dynamic element in soil. However, these studies have been limited regarding soil conditions in Paranaa. The present study aimed to evaluate the efficiency of the Mehlich-1, Mehlich-3 and ion exchange resin methods in the evaluation of available P for soybean (Glycine max) in the soils of Paranaa State. Twelve soil samples collected from the upper 0-20 cm were planted with soybean for a period of 42 days in the greenhouse. The ability to extract soil P followed the order of decreasing average amount of extracted P: Mehlich-3 > resin > Mehlich-1. The correlation coefficients between the content of P extracted by Mehlich-1, Mehlich-3 and resin and the amount of P accumulated in the plants were 0.86, 0.90 and 0.93, respectively. Mehlich-1, Mehlich-3 and resin showed similar efficiency in the evaluation of P availability to plants and, under conditions of natural fertility and in soils that had received no application of poorly natural reactive phosphates, can be used to quantify the concentrations of P in the soils of Parana State.

Boron adsorption in lowland soils from Parana State, Brazil

Boron adsorption by soil is the main phenomenon that affects its availability to plants. This, the present study investigated the effect of liming on B adsorption by lowland soils of Parana State, and to correlate these values with the physical and chemical properties of the soils. Surface samples of three lowland soils [Gleissolo Haplico (GX), Plintossolo Haplico (FX) and Cambissolo Haplico (CX)], with different origin material and physicochemical properties were used. Samples with or without liming application were incubated during 60 days. Boron adsorption was accomplished by shaking 4.0g soil samples, for 24 h, with 20 mL of 0.01 mol L-1 CaCl2 solution containing different concentrations of B (0, 1, 2, 4, 8 and 16 mg L-1). Sorption was fitted to non-linear form of the Langmuir adsorption isotherm. The adsorption isotherms indicated that the B adsorption increased with its increasing concentration in the equilibrium solution. Maximum adsorption capacity of B ranged from 3.0 to 13.9 mg kg(-1) (without liming) and 14.7 to 35.7 mg kg(-1) (with liming). Liming increased the amount of adsorbed B in Gleissolo Haplico and Plintossolo Haplico soils, although the bonding energy has decreased. The amount of adsorbed B by Cambissolo Haplico soil was not affected by liming application. The most important soil properties affecting the B adsorption in lowland soils were pH, clay content, exchangeable aluminum and iron oxide contents.

A percepção da fiscalização dos contratos de mão de obra terceirizada pelos agentes envolvidos nesse processo no âmbito da Universidade Federal do Rio Grande do Norte: uma análise sob o modelo do principal-agente

Outsourcing has emerged as one of the new ways of guiding the work. For its advantages and be consistent with the paradigms of managerial reform, outsourcing also started to be used in the Public Administration. However, taking into account the particularities of the latter, some issues are relevant when outsourcing concluded with the State. Gains notoriety, for example, the step of monitoring these contracts, to the extent that, from this activity, we can avoid the negative effects of outsourcing like the fact that the state will pay for labor and wage liens that are obligation of the company providing the services. This study aims to understand the perception that this process is under the Federal University of Rio Grande do Norte, from the point of view of different stakeholders, also explaining the motivations that these agents have to perform the supervisory process. As a theoretical basis was used the Agency Theory, which reinforces the supervisory activities as a necessary means to minimize moral hazard and adverse selection, seeking to understand not only the different motivations tax contracts to properly perform their duties, but also analyze other phenomena arising from this contractual relationship. To achieve the proposed objectives, were taken a literature review and a presentation of how to organize the management and oversight of contracts in UFRN. The methodological procedures included questionnaires and interviews with those involved in the process. After analyzing the results obtained in the survey instruments , and also based on the laws, regulations and instructions governing the procurement process within the UFRN, it was concluded that the process of overseeing the outsourcing of labor contracts in UFRN is not fully institutionalized, some points should be strengthened in order to have the consolidation of this process, highlighting the need for training of UFRN servers that act as tax, the knowledge that the contractual penalties are applied effectively, the need that there is a supervisor of tax of contractors and also the realization of the rotation system of outsourced employees

Os significados do tabagismo construídos na dinâmica social

The present study has the purpose of catching the significances of smoking in the social dinamics based on the Theory of Social Representations. It was developed among adults with ages from 20 to 59 years, low social and economic conditions, at Natal RN, Brazil. The Free-words Association Test was applied as the instrument of data collection and a semi-structured interview with the smokers and non-smokers, besides a structured interview with smokers, non-smokers and ex-smokers. All data was analyzed by the descriptive statistics using the Analysis of Content Technique of the thematic kind and by the softwares ALCESTE and EVOC 2000. Elaborations about smoking were marked by social, cultural and historical dimension, however they showed sensibility to changes and revealed positive and negative aspects of the habit. The analysis of the semi-structured interviews showed the following categories and under-categories respectively: Initiation of the habit (Friends and Family and Appreciation and Beauty); Psychosocial Implications of smoking (Personal relationship, Work and Financial); Behavior when facing smoking (Positive, Negative and Neutral); Smoking Effects (Smokers´ health and the other people health); Description about oral diseases ( Bad breath, Oral cancer and Dental problems); Smoking treatment (Physician and psychological, Supernatural and Difficulties). ALCESTE analysis presented 4 classes: Ambivalence between pleasure and get ill, Smoking as a trouble and danger to society, Social discrimination of smokers and Mouth as a place of reaffirmation of the discrimination. Those helped us to understand the psychosocial repercussion of the habit. On the social representation structure we identified as a probable central nucleus of the smoker group the categories Pleasure and Bad to the health and as peripheral elements Alcoholic Drink, Financial damage and Nervousness. For the non-smoker group the category Bad to the health comes first and Stop Smoking comes as a peripheral element. Finally, we hope that the knowledge of these representations can contribute to plan and/or to rethink over the professional practices and public policies related to smoking. Besides that, for an amplified comprehension of the study object the discussions over the identified representations should be deepen and amplified to other population and social groups

Significados de família para crianças em abrigo

This research explores the meanings of family for institutionalized children. It identifies, more specifically, how the relationship between the child and his/ her family is. The field work was developed at a municipal shelter in Natal/RN, which houses children aged between 7 and 11 years old. The subjects of research consisted of three children: two boys and one girl. Besides age-group criterion, which facilitates the use of oral language and the procedures, we took into consideration another selection criterion: children whose family configurations were similar. In order to achieve the objectives, we used toys, pictures, collages and semi-structured interviews. Data were examined under the Thematic Content Analysis, with three thematic categories previously chosen: Configuration of geographic area, family composition and family s internal dynamics. Among the results, we highlight that, for children, the concept of family is based essentially on existence of affection ties, regardless of kinship. Through this study, we hope to contribute to the discussion on the rights of institutionalized children, concerning their need of experiencing family life and living in community

Adolescência e ato infracional: a família em conflito

Numerous studies discuss the issue of adolescent in conflict with the law from the adolescent that committed infraction or from his perceptions. Taking into account the importance of the family in the life of all subject in development, this study sought the look of the families about the infraction of their adolescents under socio-educative measures. For this purpose, semi-open interviews were conducted with 20 families, ten of the boys and equal number of the girls. The institutions where the measures are applied in Natal / RN gave space for most family members to be interviewed. The data collected were arranged in tables and analyzed qualitatively following the socio-historical perspective. The survey revealed that the meanings attributed to the time of conflict with the law of the adolescents differ between the boys families and the girls . Most of the boys families see the infraction as a consequence of the influence of bad company, as a minor provocative of changes in the family s relations, left justified in a context marked by violence. Now for most part of the girls families, the infraction is seen as their responsibility, as generator of transformations within the family both emotional and economic , and inaugurates a search movement for conflicts resolutions. Through the testimonies of these families, it became evident that there was a family reality structured also by a conflicting social, economic and community context. Thus, before there is an infraction that demarcates the conflict in adolescence, there is a family in conflict.

Iniciação sexual e fatores associados: um estudo com adolescentes escolares

A iniciação sexual é um marco significativo na vida do indivíduo, ocorrendo geralmente na adolescência. Importantes transformações biopsicossociais ocorrem nesta fase, denotando vulnerabilidades à vida do adolescente, dentre elas, as decorrentes da iniciação sexual, sendo o risco de infecção pelo HIV/aids a mais grave. A infecção pelo HIV/aids constitui atualmente um importante problema de Saúde Pública, estando os jovens no centro da epidemia mundial. No Brasil, dados do último boletim epidemiológico, lançado em 2013, apontam para a tendência de aumento de sua prevalência na população jovem. Desta forma, o presente estudo teve por objetivo investigar a associação entre iniciação sexual e o perfil sociodemográfico, o indicador de conhecimento das formas de transmissão do HIV/aids e fatores biopsicossociais autoestima e habilidades sociais, em adolescentes de 16 a 19 anos, de ambos os sexos, estudantes do nível médio técnico integrado, do Instituto Federal de Educação, Ciências e Tecnologia do Rio Grande do Norte, Campus Natal. Trata-se de um estudo transversal, cuja amostra foi constituída aleatoriamente por 200 alunos que responderam de forma anônima a quatro instrumentos: perfil sociodemográfico, questionário da Pesquisa de Conhecimentos, Atitudes e Práticas na População Brasileira (PCAP), Escala de Autoestima de Rosenberg e o Inventário de Habilidades Sociais para Adolescentes de Del-Prette (IHSA). A análise estatística dos dados foi realizada através do teste qui-quadrado de Pearson e do exato de Fisher (α <5%). A média de idade para a primeira relação sexual foi de 15,96 anos, com o início mais cedo para o sexo masculino. Verificou-se associações estatisticamente significativas entre iniciação sexual e as seguintes variáveis: idade, sexo, situação conjugal, religião, renda familiar, autoestima e o repertório de habilidades sociais. Observou-se ainda que apenas 11% dos adolescentes possuíam conhecimento correto acerca das formas de transmissão do HIV/aids. Conclui-se que os esforços para a prevenção das DST/aids precisam ser direcionados a campanhas e programas mais eficazes, que considerem não somente o caráter informativo, mas também os fatores psicossociais já que estes mostraram-se associados ao início da vida sexual
