Clima organizacional e satisfação laboral: um estudo sobre os núcleos hospitalares de epidemiologia de Natal/RN

The Hospital Epidemiology Nucleus (NHE) is a structure that has a specific organizational climate, which influence the level of job satisfaction among professionals working in it. This is a descriptive study with a quantitative approach, aimed to identify the relationship between organizational climate in the NHE regulated in the city of Natal / RN and the job satisfaction among its professionals from the perspective of theoretical issues about Organizational Development. The research was carried out in 13 hospitals with different kinds of sponsorship, 9 public, 3 philanthropic and 1 private. Data were collected using the instrument "organization in hospitals: issues relating to climate and job satisfaction , with 33 professionals appointed and active on NHE. This study obtained an appropriate consent of the Research Ethics Committee of the Hospital of Pediatrics Professor Heriberto Ferreira Bezerra, from the Riograndense Northern League Against Cancer and the Federal University of Rio Grande do Norte. Data collected were organized and treated with simple descriptive statistics. It was observed that from 33 of surveyed people, 93% was female, had an average of 40 years old age, with activity duration between 1 and 2 years (84.9%). Furthermore, 45.5% of industry professionals were nurses. It was identified that professionals working in NHE perceive and experience its work environment as an Organization Structure in construction. It was found that with the exception of the aspects "working life", "socio-cultural" and "organizational culture , the other internal and external factors to the NHE does not have strong expression in the forming of an organizational climate conducive to the development of the sector. It was found that 70% of interviewed perceive the organizational climate as favorable for the industry's progress. Regarding the job level of satisfaction, respondents feel fairly satisfied with the organizational structure. Therefore, the results of this study are suggestive that there is some factor that is greatly contributing to a healthy organizational climate that encourages the industry team members of the NHE present behaviors that identify them as actors committed and satisfied with the work, even face of all obstacles to implementation of epidemiological surveillance. Thus, it is suggested for futures studies to seek to determine how the organizational culture, while significant internal factor, influencing the organizational climate establishment of NHE and therefore the level of job satisfaction and well-being of each members of the team

Uma análise exploratória da jornada flexível de trabalho sob a perspectiva de tutores na educação a distância

Information Age has been providing accelerated development of technologies in teaching, which is making the increase in distance courses and flexibility in the tutors everyday work. In this context, it was aimed to study the influence of flexible work in the development of activities and personal life of the tutors in Distance Education at Universidade Federal do Rio Grande do Norte. More specifically, they have been sought to compare the types of flexibility detected, identifying the extent of the day's work in mentoring; investigating the relationship between flexible working time and productivity; evaluating the Quality of Working Life (QWL) and for Work and Family Relationship of the tutors. Thus, work is justified by the importance of academic and organizational achievement. To meet the goals, it was obtained a sample of 75 respondents (45.73% of the population). The data collection instrument was comprised of 48 variables mainly based by Walton (1975) and Paschoal, Tamayo and Barham (2002). The statistical techniques used were: analysis of frequency, ratio test, factor analysis and regression. The results collected have shown that the presence and distance tutors experience similar realities, but have different profiles; the day of their work is on average three hours daily; in view of the tutors, flexibility has a relation with the production, QWL work-family balance were evaluated in a satisfactory manner and the statistical techniques used have shown significant influence between the QWL and flexible working day. It is therefore concluded that flexibility at work can influence the development of activities and personal life of the tutors. Thus, the flexible working day may be used in a strategy way of routine in many organizations

Obtenção de emulsões asfálticas convencionais e modificadas com argilas e nanoargilas

The increasing demand for asphalt leads to the development of techniques that can improve the quality of products and increase the useful working life of pavements. Consequently, there is a growing application of asphalt emulsions, which are produced from a mixture of petroleum asphalt cement (CAP) with an aqueous phase. The main advantage of asphalt emulsions is its cold application, reducing energy costs. Conventional emulsions are obtained using asphalt, water, solvent, and additives. The modified asphalt emulsion is developed by adding a modifying agent to conventional emulsions. These modifiers can be natural fibers, waste polymers, nanomaterials. In this work modified asphalt emulsion were obtained using organoclays. First, it was prepared a conventional asphalt emulsion with the following mass proportion: 50% of 50/70 penetration grade CAP, 0.6% of additives and 3% of emulsifier, 20% of solvent and 26.4% of water. It was used bentonite and vermiculite (1% and 4%) to obtain the modified asphalt emulsion. Bentonite and vermiculite were added in its raw state and as an organoclay form and as an organoclay-acid form, resulting in 26 experimental runs. The methodology described by Qian et al. (2011), with modifications, was used to obtain the organoclay and the organoclay-acid form. infrared spectroscopy (IR)) were used to characterize the clays and nanoclays. The emulsions were prepared in a colloidal mill, using 30 minutes and 1 hour as mixing time. After, the emulsions were characterized. The following tests were performed, in accordance with the Brazilian specifications (DNER- 369/97): sieve analysis, Saybolt Furol viscosity, pH determination, density, settlement and storage stability, residue by evaporation, and penetration of residue. Finally, it can be concluded that the use of nanoclays as asphalt modifiers represent a viable alternative to the road paving industry
