With the need of the companies in becoming more competitive within the market, it arises an incessant search for selective human potential, with a high level of capacity and low rotativity, which motivation results in production raise, quality optimization and waste reduction. This scenario requires a strategy development which advantages the Human Resources Quality Management. This way, the model of the Human System Audit (HSA), developed by the Spanish researchers Ouijano and Navarro, presents itself as an important tool to diagnosis and evaluation, contemplating the environment where the organization is inserted, its strategies, its organizational design, its processes and its organizational effectiveness. In this sense, the present study has identified the existent relation between the professional satisfaction and the Organizational Culture, based in the model HSA. The research has been a quantitative-descriptive one and has had as population the technical-administrative workers from the Federal Center of Technical Education of Rio Grande do Norte (CEFET RN). The data collection has occurred during May, 2008, by means of the application of a questionnaire in the HSA model. The sample was composed by 167 subjects, distributed among the Five units of the institution. It was used the factorial analysis, with the extraction method of main components and orthogonal rotation varimax, in order to extract the dimensions of the satisfaction and of the organizational culture and the calculation of Cronbach s Alpha coefficient, to evaluate the reliability of these dimensions. The factorial analysis of the satisfaction indicators has identified four factors,, all of them showing significance: gratefulness and relationship , self-realization , stability and security and physical conditions and social benefits . The result of the factorial analysis with the indicators of the organizational culture has extracted four factors and among them, three of them have obtained significance: Personal Satisfaction Style , Competitive-Denial-Power Style and the Conventional-Dependent Style . After identifying the dimensions of the satisfaction and culture found at CEFET-RN, it has been notice the existence or not of relation among them, through the application of Pearson s coefficient. It has been verified that all of the dimensions of the Professional satisfaction are correlated with some dimension of the organizational culture, having in outstand position, with higher intensity, the relation between the culture style of Personal Satisfaction and the satisfaction factor referring to the self-realization

The principal purpose of this research was to investigate discriminant factors of survival and failure of micro and small businesses, and the impacts of these factors in the public politics for entrepreneurship in the State of Rio Grande do Norte. The data were ceded by SEBRAE/RN and the Commercial Committee of the Rio Grande do Norte State and it included the businesses that were registered in 2000, 2001 and 2002. According to the theoretical framework 3 groups of factors were defined Business Financial Structure, Entrepreneurial Preparation and Entrepreneurial Behavior , and the factors were studied in order to determine whether they are discriminant or not of the survival and business failure. A quantitative research was applied and advanced statistical techniques were used multivariate data analysis , beginning with the factorial analysis and after using the discriminant analysis. As a result, canonical discriminant functions were found and they partially explained the survival and business failure in terms of the factors and groups of factors. The analysis also permitted the evaluation of the public politics for entrepreneurship and it was verified, according to the view of the entrepreneurs, that these politics were weakly effective to avoid business failure. Some changes in the referred politics were suggested based on the most significant factors found.

This research aims to understand the factors that influence intention to online purchase of consumers, and to identify between these factors those that influence the users and the nonusers of electronic commerce. Thus, it is an applied, exploratory and descriptive research, developed in a quantitative model. Data collection was done through a questionnaire administered to a sample of 194 graduate students from the Centre for Applied Social Sciences of UFRN and data analysis was performed using descriptive statistics, confirmatory factorial analysis and simple and multiple linear regression analysis. The results of descriptive statistics revealed that respondents in general and users of electronic commerce have positive perceptions of ease of use, usefulness and social influence about buying online, and intend to make purchases on Internet over the next six months. As for the non-users of electronic commerce, they do not trust the Internet to transact business, have negative perceptions of risk and social influence over purchasing online, and does not intend to make purchases on Internet over the next six months. Through confirmatory factorial analysis six factors were set up: behavioral intention, perceived ease of use, perceived usefulness, perceived risk, trust and social influence. Through multiple regression analysis, was observed that all these factors influence online purchase intentions of respondents in general, that only the social influence does not influence the intention to continue buying on the Internet from users of electronic commerce, and that only trust and social influence affect the intention to purchase online from non-users of electronic commerce. Through simple regression analysis, was found that trust influences perceptions of ease of use, usefulness and risk of respondents in general and users of electronic commerce, and that trust does not influence the perceptions of risk of non-users of electronic commerce. Finally, it was also found that the perceived ease of use influences perceived usefulness of the three groups. Given this scenario, it was concluded that it is extremely important that organizations that work with online sales know the factors that influence consumers purchasing intentions in order to gain space in their market

Currently the organizations are passing for continuous cycles of changes due to necessity of survival in the work market. The administration of the future points a way to the organizations of today and tomorrow, the search of the competitiveness from loyalty and motivation of its staff. Of this form, the model of the Auditoria do Sistema Humano (ASH), developed for Spanish researchers and that now it is being applied in Brazil, contemplates a series of dimensions about Human Resources management quality in the companies and the organizational effectiveness, such as the environment where the company is inserted, the strategies, the organizational drawing, the psychological and psychosocial processes, e the reached results. In this direction, the present research analyzed the factors of job satisfaction and organizational commitment, making, also, a relation of causality between the same ones. The quantitative-descriptive research had as population the employees of twenty three nourishing industries of the State of Rio Grande do Norte (Brazil), registered in the Federacy of the Industries of the state. The collection of the data occurred for the months of October of 2005 and March of 2006, by means of the application of questionnaire of model ASH. The sample was composed for 197 employees, however it was observed presence of five outliers, that they had been excluded from the analysis of the data. To extract the dimensions of the satisfaction and the commitment and identification the factorial analysis was used, with extraction method of principal components, rotation Varimax and normalization Kaiser. The gotten dimensions had been evaluated with the calculation of the coefficient Alpha of Cronbach. The factorial analysis of the pointers of the organizational commitment and identification had extracted ten factors. Of these, four had gotten significance of the analyses inside: affective commitment, values commitment, continuance commitment and necessity commitment. The result of the analysis of the pointers of job satisfaction indicated four factors: extrinsic, motivations, relation with the friends and auto-accomplishment. To deal with the data the relation between job satisfaction and organizational commitment it was used technique of multiple regression. The correlation between commitment and satisfaction was satisfactory, detaching the affective commitment with bigger index of correlation, followed of the affective one

This study shows the results of an exploratory-descriptive research that aimed to identify the latent dimensions of communication, as well as finding relations between such dimensions and organizational image. The sample came to a total of 267 respondents, being 89 managers or owners and 178 salespeople of clothing and footwear stores that are situated in the main five shopping centers located in Natal, capital of Rio Grande do Norte. The collection of the data was made by the use of two structuralized and validated instruments, being the answers measured in the likert scale of 6 points. For the measurement of communication it was used the instrument developed by Downs and Hazen (2002), made up of 8 latent dimensions and 32 indicators. For the image it was used the model of Mael and Ashforth (1992) that contains 5 indicators. The analysis of the data was made through of the use of statistical techniques of factorial analysis and structural equations modeling. The results of the factorial analysis demonstrated communication as being formed by five latent dimensions. The modeling, on the other hand, demonstrated to exist positive relations between communication and organizational image, whose results revealed that the image is influenced by the communication with the supervisor, by the organizational integration and as being stronger explained by the vertical communication

The present study had as objective translates, to do equivalence and validation of the Utian Quality of Life (UQOL) for the Brazilian population through methods internationally accepted, in which the original questionnaire was translated for the Portuguese by three teachers and the consensual version was translated back for English by two American teachers (back translation). A multidisciplinary committee evaluated all versions and the final version in Portuguese was applied to climacteric women for the process of adaptation. Validation of the instrument was performed by measuring the reliability and validity properties. Construct validity was examined through the comparison between UQOL and the general measuring scale of quality of life Short Form-36 (SF-36). The final version of translation process was easily recognized by the target population, that didn't tell understanding problems. The results obtained for the reliability intra and interobserver showed significant agreement in all of the subjects. The construct validity was obtained through correlations statistically significant among the domains occupational, health and emotional of UQOL with the SF-36 domains. For the exploratory factorial analysis, it was verified that three factors explain 60% of the total variance of the data, the present study allowed concluding that UQOL was appropriately translated and adapted for applicability in Brazil, presenting high reliability and validity. In that way, the executed project provided the involvement of different areas as gynecology, psychology and physiotherapy (interdisciplinary). Thus, this instrument can be included and used in Brazilian studies to assessment the quality of life during the climacteric years

The Nursing Process (NP) is considered as the dynamics of the systemized and inter-related actions of human care. We believe that the nursing manager, as the representative of all the nursing care provided in the hospital setting, is an important agent for the implementation of institutional policies, such as the NP, in the service. However, there is little information in the literature about the NP in the perspective of the nurse manager. The objective of this study was to analyze the viability of the Nursing Process in the hospital context based on the attitudes of the nurse managers toward the Process. We conducted a descriptive-exploratory research study, of quantitative approach, with a population of 45 nurse managers that worked in the state hospitals located in Natal, RN and in the university hospitals of the UFRN. Two instruments were used for the collection of data: a nursing process questionnaire, constructed for use in this study, and the scale for the measurement of the attitudes titled Positions on the Nursing Process. The population is predominantly feminine (91,0%) and have relative nursing practice experience (Mean=17,6 years). However, they have little experience in management (Mean=8,6 years). They express little knowledge of the PE nursing terms and little experience with the Process. They have a positive atitude toward the NP (Mean = 110,9); are favorable to its developement in the service (86,7%); 48,9% indicated little possibility of institutionalization in the service and 37,8% indicated large possibility. The Spearman test for association between the variables of attitude about the NP and the possibility of its institutionalization demonstrated a weak negative association in the total individual scores of the attitudes (-,316) as in the 20 itens of the instrument, with coefficients varying from 0,014 to 0,464. Factorial analysis of the instrument identified three underlying factors to the attitudes of the managers in this study: relevance, operationalization and collaboration, with Cronbach Alpha coeficients of 0,955, 0,844 and 0,807, respectively, and 0,956 for the whole instrument, indicating that the scale and its factorial subscales have internal consistency. We conclude that there is a weak tendency for the managers with a favorable attitude to have a negative perception about the possibility of institutionalization of the NP in the service. The favorable position does not appear to be sufficient for the viability of this methodology in the hospital sector, results that is worrisome for nursing. This situation suggests that the difficulties with the institution of the NP in the hospitals may be related to other factors, including the organizational conditions. We believe that the institucionalization of the NP in a servisse where it is not known and not practiced, constitutes the introduction of an innovative work technology that involves many demands, among them the adherence of the persons to the proposed innovation. This demands time and the institutional adjustments and the human resources necessary. In this process, the involvement of the health professional of the institution is necessary. This situation brings to light the discussions of professional autonomy, the action limits and perspectives, the redefinition of roles, delimiation (or consensus) of the objects of study and of the work processes, among others.

In recent decades higher education in Brazil has gone through several changes. The Programa de Reestruturação e Expansão das Universidades Federais REUNI has been the greatest overhaul performed by the government in public universities in the last years. REUNI is presented as the biggest reform in tertiary education in contemporary times, having as the main goal a gradual increase in the average rate of conclusion in live learning graduation courses up to 90%, as well as a rate expansion of graduating students in face to face classes per professor. This research aims at studying the perception of professors from UFRN concerning the REUNI program in execution from 2008 until 2012. The study seeks to understand how professors evaluate the program and what the dimensions that most influence in this evaluation are. The study made use of a research tool (survey) which was sent through the internal system of the university, SIGAdmin, to all professors of superior teaching from UFRN. The answers generated by the survey were processed using SPSS statistical software (Statistical Package for Social Science). Factorial Analysis and Multiple Linear Regression were used as an analysis technique. 180 answers were obtained, reaching all UFRN Centers and some academic units, as well as some campuses in the countryside of the state. Through the research was possible to analyze how professors from UFRN perceive the REUNI program implemented in the institution. The results point to the program approval by the professors. Statistical tests showed that the average values obtained in the Centers and academic units are basically the same. It was demonstrated that the extent that most influenced in the answers is linked to practical outcomes of the program, whereas the knowledge of REUNI goals was the least that impacted on the marks given to the program. Another dimension which influenced the perception of professors relates to the influence of REUNI in their activities. It was observed that professors from UFRN don t see REUNI as an impediment to them

This work presents the processes and the results of a research concerning the affectivity in children suffering from the Down´s Syndrome (DS). The relevance of the study is justified due to the need of the development of researches, in the area of psychological evaluation of people who suffers from Down´s Syndrome (DS), that are backed by the use of appropriate instruments for such purpose. The thematic discussed focuses the characteristics of the affectivity of children suffering from Down´s Syndrome. Affectivity, conceptually, is considered a wide phenomenon, including several aspects such as emotions, passions, anxiety, anguish, sadness, happiness and even the pleasure sensations and pain. The general objective of the study consisted of investigating the manifestation of the affectivity in children and young with Down´s Syndrome and the parents´ and educators´ perception concerning the expression of the affectivity in the behavior and in the social activities. The specific objectives were: to identify the parents' perceptions about the several manifestations of indicative behaviors of affectivity; to verify in the social atmosphere, outside home, through the teachers' perception, the several forms and intensities of the expression of the affectivity; and, to make possible the use of the technique of Zulliger (Z-test) in people with Down´s Syndrome. 70 (seventy) children and young with Down´s Syndrome participated in the research, in the age group from 04 to 26 years old, which are attended by Institutions of Paraíba and of Rio Grande do Norte. The instruments used were two questionnaires, applied with the parents and teachers, and the projective technique, Z-test, applied, individually, with the children and young with Down´s Syndrome. For analysis of the data of the questionnaires, the program Trideux-Mots was used, with the intention of selecting the main outstanding words for the parents and teachers concerning the expression of the children's affectivity and young with Down´s Syndrome. For so much, it was organized a database that was processed by that program and, soon after, interpreted through the Factorial Analysis by Correspondence (AFC), looking for to clear the modalities of presented answers in an organized way, through a graph. The data of the Z-test were analyzed, taking in consideration the need to characterize the aspects of the affectivity and the elaboration of specific norms for this sample type, through normalized scores. In agreement with the data presented by Tri-deux-Mots, it was observed that in the affective behavior and in the relationship with the other, home and in the school, the children and young with Down´s Syndrome they express your affectivity through positive and negative characteristics, in the same way that any other child that doesn't have to syndrome. The Z-test made possible initial elements to work with that population, however it is necessary that grow other researches with the intention of investigating the reason of the answers they present not the specific categories that you/they are related to the affectivity, since it was well-known the diversity of affective characteristics presented by the researched group

Parenting styles concern overall interaction characteristics between parents and children. To assess them, it is important to build and adapt valid and reliable instruments. The main objectives of this dissertation were to translate, adapt and evaluate the psychometric properties of the Young Parenting Inventory (YPI) for the Brazilian context, as seek associations between the YPI and Familiogram Test (FG). In current study, YPI was adapted to Portuguese by backtranslation method. Content analyses were made by five judges. 920 high school and college students (543 females), whose ages were between 14 and 69 years (M = 21.3, SD = 6.1), filled out the research instruments. Data were collected in Natal, Petrolina and Brasilia cities and Porto Alegre metropolitan region. The results confirmed the existence of five factors. Final version of the YPI was composed by 49 items. Exploratory factorial analysis (principal components) were conducted using oblimin rotation. Five factors extracted explained 45.12% of the maternal scale variance and 47.59% of paternal scale. Each factor explained, at least, 3% of the variance and showed Eigenvalue over than 1.5. All items have factorial loadings values above 0.3. The confirmatory factorial analysis has showed fit statistics reasonably adequate: for maternal scale,  ² [1114] = 4636.38, p < 0.001,  ² / df = 4.16, with GFI = 0.83, AGFI = 0.81 and RMSEA = 0.06; for paternal scale,  ² [1114] = 5133.69 p < 0.001,  ² / df = 4.61, with GFI = 0.81, AGFI = 0.79 and RMSEA = 0,06. Thus, final instrument was composed by the following factors: (I) Disconnection and Rejection ( = 0.89 and 0.90), (II) Affectivity and Emotional Stability ( = 0.85 and 0.88); (III) Overvigilance and Other Directedness ( = 0.83 and 0.85), (IV) Overprotection and Impaired Autonomy ( = 0.78 and 0.79) and (V) Impaired Limits ( = 0.66 and 0.71). Finally, relations between the YPI and FG were assessed. Pearson's correlations between the YPI and FG showed moderated associations, particularly between the factors Affectivity (YPI) and Affection (FG) (r = 0.69 and 0.7 for maternal and paternal scale, respectively); and the factors Disconnection and Rejection (YPI) and Conflict (FG) (r = 0.59 and 0.58). The regression models indicated that over than 40% of variance of factors of FG can be predicted by factors of YPI. Beta coefficients for Affection-Affectivity relation were 0.67 (maternal scale) and 0.53 (paternal scale); for Disconnection-Conflict relation were 0.31 (maternal scale) and 0.44 (paternal scale). We conclude the YPI has adequate psychometric parameters and can be used in future research in this area. However, adjustments in the structure of the YPI were made. Moreover, it is suggested further studies to consider other samples and variables, increasing the knowing of parenting styles and the Young‟s theory in the Brazilian context

Millon describes the normal personality by means of adaptation styles that are effective in normal environments and personality disorders such as unadapted operating styles. To operacionalize his theoretical model, Millon has built several instruments, including the Millon Clinical Multiaxial Inventory III (MCMI-III), wich consists of a self report inventory composed by 175 true or false response items, containing four verification scales, and others scales wich evaluates 14 personality patterns and 10 clinical syndromes. The Substance Dependence scale (T) is placed along with Clinical Syndromes scales. This research is justified by the lack of a Brazilian instrument to assess personality psychopathological aspects, and aims to translate and semantically adapt the MCMI-III to the Brazilian context, checking validity elements of the Substance Dependence scale, and developing a computer application for assisting the evaluation of assessment results. To this intent, 2.588 individuals data was collected, male and female, aged between 18 and 85 years, characterized as belonging to a clinical or non-clinical group, who took part in the survey via the internet or in person. Respondents completed the MCMI-III, a socio-demographic questionnaire and a subgroup also answered to the Goldberg General Health Questionnaire (GHQ). Besides descriptive statistics, we performed the analysis using the Student t test, principal components analysis and internal consistency. Despite difficulties related to translating very specific English terms, the assessment by judges, experts on Millon´s theory, and the back translation, attested the adequacy of the Brazilian version. Factorial analysis indicated the grouping of translated T scale items into three factors (social activities prejudice, lack of impulse control, and oppositional behavior), by presenting a single item on a fourth factor (apparently related to seeking pleasurable stimuli). The Cronbach alpha for this set of items was 0,82, indicating an acceptable scale reliability. The data analysis resulted in distinction of scores between clinical and non-clinical groups and between men and women; the relationship between high scores on the scale T and the other scales; scores of drug users according to the declared used substance; and the relationship between high scores on T and the verification of disorder or risk on GHQ mental health factor, indicating the instrument´s adequate sensistivity in identifying psychopathologies and the relationship between the different disorders or psychopathological personality patterns. Although further studies are necessary to develop the scores transformation factors, the computerized correction tool was adequate.

The process of development of any area is closely linked to teaching and research, and in Tourism it is not different. Thus, in this area in which service is one of the factors intrinsically related to its success , it is observed the need for people with deep and critical training in the various aspects of this activity acting in this sector. However, we can see the existence of some differences between what is offered by the academy from what is required by the market. Therefore, the objective of this research is to verify the relationship between higher education in Tourism and labor market through the perception of the bachelor in this area, graduated in Natal-RN, since it is the tourismologist who makes the link between this two fields. To know the perception of these tourismologists, it was necessary to apply a questionnaire to those ones graduated in the years 2009 and 2010. In accordance with the aim of this study, this research was exploratory-descriptive. Related to the technical procedures, it was a documentary, literature and field research. To have it analyzed, some qualitative and quantitative techniques were applied according to our specific objectives and the types of data collected, such as: content analysis, factorial analysis to synthesize the information and identify the basic dimensions that represent the different variables studied, the standard deviation to verify the variation of the responses in some items and the correlation technique that allows the analysis of the relationship between two variables. In response to the objectives proposed here, we could finally conclude that: the syllabuses of these courses are too general and the graduates themselves consider them so. It was diagnosed that the graduates 1) are mostly female, 2) a very small part of them is working in the area that they are graduated in, and 3) not all of them receive satisfactory wages which contributes to having a negative view of their degree course. Moreover, the educational institution where they studied was not a decisive factor to get a job. It was still diagnosed that most part of them do not have positive perceptions when thinking about the future of their careers as bachelors in Tourism. Many of them, including, if it was possible to change something in their careers so far, they could have chosen another college degree. It was found that, although there is a negative perception about their professional future, almost half of them believe that the course met the needs of the market. However, those ones that are not working have a more positive point of view related to the applicability of higher education. On the other hand, the other ones who already worked in this area have a more negative perception about it and do not believe that the course meets the market's needs. In summary, this study allowed the understanding of the existence of some gaps that exist between higher education in Tourism and the market needs, professionally speaking, thus contributing to the spreading of ideas on that subject for teachers, researchers and the current and future students of the area.

Objectives: To determine the effects of ultrasound therapy on the femur and tibia growth in young rats. Method: Four-week-old male Ratus Norvegicus totaling 115 animals, divided into four groups, were submitted to ultrasound therapy (0.8 MHz, fixed tube head, continuous pulse, for 10 minutes, once a day, ten times) on the medial face of the right knee, with powers of 0.0 W/cm2 (group 31), 0.5 W/cm2 (group G2), 1.0 W/cm2 (group G3), and 1.5 W/cm2 (group G4). Histological slides of the epiphysis, growth plate and metaphysis and the femoral and tibial length measurements were studied in the sixth, thirteenth and twenty-sixth weeks of life. The data were submitted to factorial analysis of variance according to a one-way layout. Results: No statistically significant bone growth alteration was established between any of the three treated groups and the control group. However, alterations in femoral and tibial growth suggesting a decrease in G4 in relation to 02 and G3 were noted. In G4, histopathological alterations, such as cellular necrosis and post-necrosis bone neoformation were found. Conclusion: According to this study, no statistical evidence of bone growth stimulus or inhibition resulting from the application of ultrasound therapy was found when comparing the treated groups with the control group. Histological alterations regarded as pathological were only observed in G4. Also, smaller significant bone growth was found in G4 compared to G2 and G3. Level of Evidence: Level II, cross-sectional study.

This study started from the hypothesis of the existence of a relation between the type of the urban occupation concerning to the sustainability conditions at the proximity of Environment Protected Zones and the occurrence of vectors insects in Natal, Rio Grande do Norte, Brazil. This research, which used data available by the City Administration Health and Urbanization Secretaries (respectively SMS and SEMURB), in the time period of 2006 to 2008, aimed to characterize the study site in terms of urban occupation, relating it to social environmental aspects of land occupation and the occurrence of vectors insects. This study is presented in two papers, the first one linking the occurrence of vectors insects and sustainable development indicators and the second relating the incidence of reported cases of Dengue and Dengue Hemorrhagic Fever (DHF) and the occurrence of larvae infection indexes of Aedes aegypti, in Natal, Rio Grande do Norte State. In the first paper, was made a correlation between Dengue Fever vectors and Visceral and Tegumentar Leishmaniasis vectors and sustainable development indicators, selected from IDS Brasil- 2008. Through factorial analysis a Sustainability Index (SI) was acquired for each region, the northern region of the municipality obtained lower numbers than southern region, which, in its turn, presented better sustainability conditions. Linking this index to vector infestation parameters shows a high significant correlation between the SI and the Breteau Index of Aedes aegypti (p=0,028) as well as with SI and sand flies infestation index (p=0,01). Higher rates in vectors infestation in regions with a lower Sustainable Development Index demonstrates that this index can be used to determine the increasing of probability of Aedes and sand flies occurrence in urban environment. The second paper analyzed the occurrence of the main vector of Dengue and DHF, the Aedes aegypti mosquito, and the relation between larvae infection indexes of this insect and reported cases of the diseases. This study revealed unexpected relation where areas with higher Breteau s Indexes showed lower infection rates of Dengue Fever, although showing high incidence of DHF
