Scale an organization's server framework is a task of the most significant area of human resources, however, difficult to implement, since account the work force may not be enough to put people trained in strategic locations or with specific profiles to meet organization's needs. From 2005, with the implementation of the Plan of Careers of technical and administrative positions of Education Federal Institutions, the staff dimensioning it became mandatory task for efficient management, for the preparation of the Technical Development Plan, approved in 2006 requires the adequacy of the server framework from a model of allocation of positions. In the same year of the Technical Career Plan the Federal Government launched the guidelines for implementation of the National Staff Development Policy federal government and brought to the public service, management by competence, whose purpose is to provide improved services to citizen, emphasizing the efficiency, effectiveness through the ongoing development of the server and the adequacy of their skills to the organization's objectives. Considering this context, the research in question had an exploratory nature to seek to discuss the integration of Management Skills with the subsystem staff dimensioning, and, if used the skills mapping to map the skills and delivery of crowded servers in Program graduate of UFPA, in order to qualitatively assist the design. Deliveries were also tested as quantitative variable for use in the calculation matrix. The quantitative results were obtained by means of descriptive statistics, raising the profile of the servers in relation to the link with the UFPA, education, length of service and hours of work. To calculate the matrix was used measures of central arithmetic average and median tendency to check the ideal framework server with the application of the data in a model already used by the UFPA to scale the technical and administrative staff. The work resulted in the mapping of competence and deliveries and staff dimensioning of the secretariats of graduate programs

(Universidade Federal do Pará, 2018-03-20) GALENDE, Ana Beatriz Fernandes; NEVES, Renato Martins das; http://lattes.cnpq.br/6538317425557058; DUARTE, André Augusto Azevedo Montenegro; http://lattes.cnpq.br/1135221873341973
Depreciation and Physical obsolescence of a property are aspects directly related to the useful life of the same. Aging is one of the most immediate causes of depreciation and is unavoidable. However, several factors can contribute to this, in addition, both depreciation and obsolescence are relevant factors and can not be neglected in the procedures of valuation analysis of any movable or immovable property. This work aims to perform the analysis, apply and to validate the consolidated methods for calculating depreciation and to reconcile them to the perceived reality, measuring them in a less subjective and more compatible with reality, in addition to proposing a method based on the Performance Standard in Buildings - NBR 15.575 / 2013. The obsolescence, in turn, is difficult to measure, being in this work analyzed with respect to the influence on depreciation. The research consists of a case study in 4 buildings of the Federal University of Pará, Guama Campus. A bibliographic and documentary research was carried out for the theoretical basis of the theme, followed by survey and visual / photographic inspection in the buildings, where the systems established by NBR 15.575 / 2013 - Structural, Fences, Floor, Cover and Water and Sanitation were evaluated. reports of nonconformities found. The calculation of Depreciation proceeded with the application of the consolidated methods in the literature, Kuentzle, Ross-Heidecke and Linear Depreciation, with the method elaborated based on NBR 15.575 / 2013. With the results, a comparative analysis was performed between the values obtained and the influence of age on the results was verified. There are many differences among the obtained results considering the methods that were used. These differences vary between 5% to 7000%, and subjectivity is a factor that should be treated with care at the time of this decision of some criteria. The results obtained through the method based on NBR 15.575 / 2013 demonstrated that the performance of a building is a factor or variable that must be incorporated in the methods that evaluate the building. Depreciation was verified with greater approximation of the reality when the methods were applied in which the parameters used are more consistent and objective, being the Ross-Heidecke and the NBR 15.575 / 2013 methods more compatible with the researched reality.

Feedback is the most common intervention in analyzing the technique applied to associations (OBM). Feedback is information about a performance that allows the individual to change his or her behavior in the future. Despite the large number of surveys on feedback on OBM, there are still disagreements about which forms, functions and characteristics are the most effective feedback. The present study was intended to compare the effectiveness of the feedback offered before and after the performance of an activity. Participants were assessed for “incompetent” behavior. For that, the participants went to listen to an audio. In the audio, a specific situation was necessary and the studious students, to elaborate a suitable competence. Altogether, students develop 9 skills. Participant 1 (P1) had the feedback offered late after the teaching performance, but immediately before the next performance. In the experimental condition offered to participants 2 and 3 (P2 and P3), feedback was offered immediately after the learning performance but anticipated in relation to the next opportunity to perform the task. The three different performance participants. However, P1 shows a greater growth compared to P2 and P3. The results showed that the feedback given before the realization of the next performance opportunity was more effective compared to the one after the individual's performance, considering a context with a complex task and with long intervals between the next performance opportunity. These results are related to the results in the literature in similar characteristics of task complexity and interval between separate. However, when analyzing the results of this research, limitations must be taken into account, such as the low number of participants and the impossibility of conducting the collection in person.

To evaluate the spatial information in the management of Water Supply System (ATS). For this they were defined and adopted to the survey (Phase 1), being divided into data of actual losses, commercial and operating expenses. In Phase 2, the base map of study area and data used were stored and organized in a Geographic Information System (GIS) using ArcGIS 9.3 software, which built the data model for the study, and defined the topology be used for identification of specialized data, building the database and the creation of georeferenced layers. In phase 3 was calculated from water balance in the main units of SAAs studied with certain losses in raw water supply, treatment, on the reservation, and distribution. In phase four indicators were calculated to evaluate the performance of SAAs, including: coverage index, total index of actual loss, loss index in the collection, rate of loss of business, index of energy consumption in SAA, index of energy costs Electric, among others. In phase 5 was proposed to the spatial and GIS presentation of the results obtained in earlier phases. Thus, considering the data adopted, it was possible to identify the values of actual losses and performance indicators in each sector of the SAA studied, being, for example, sector 9, which presented the highest rate of total loss, reaching 59, 10%, followed by sections 4, 8 and 5. The most significant loss for the system was the loss distribution, with 9 industry to a loss of 57% loss on treatment was 3.4% in the third sector, and sectors with the highest loss of adduction weresectors 6 and 8, with 3.5%. The percentage of water unaccounted were higher in sectors 1 and 5. Sectors 1, 3, 4 and 6 are those with the highest energy consumption per volume of water produced. Therefore, the spatial data in GIS facilitated the visualization and data analysis adopted in this research.

The research that resulted in this dissertation sought to empirically investigate the interaction between leadership and culture, as well as the effect of this interaction on the performance of manufacturing companies in the Amazon region. A multi-method methodological approach was used, starting with a Systematic Literature Review (SLR) on the aforementioned themes and object of investigation. Based on this review, the dimensions of culture and consolidated leadership styles were shown, and how they interact to contribute to companies in terms of improving organizational performance, be it operational, financial or environmental. An article was formatted with the results of the SLR, which was accepted at the XV Colloquium on Organizations, Development, Sustainability & II International Conference on Creative Economy and Public Policies. After the SLR, an empirical survey was conducted with 80 manufacturing companies located in the state of Pará, Amazon region of Brazil. In the discussions of the statistical analyses, Contingency Theory was applied to explore how contextual variables and scarce resources influence performance. The results reveal that the effect on organizational performance measures in view of the interaction between leadership styles and organizational culture adopted by companies in the Amazon Region is not homogeneous. These survey results are organized in detail in an article format.

(Universidade Federal do Pará, 2019-08-16) CARMONA, João Victor Costa; CAVALCANTE, Gervásio Protásio dos Santos; http://lattes.cnpq.br/2265948982068382; BARROS, Fabrício José Brito; http://lattes.cnpq.br/9758585938727609
Multimedia applications have been growing in recent years; new consumptions like online games, video conference, video on demand and IP telephony are some of these. However, there is a greater prominence in the search related to videos and streaming, currently in high resolutions and mostly traffic over wireless networks, mainly due to the proliferation of mobile devices and significant increase of access networks, which make it more comfortable. Providing this information is easy. Thus, as an immediate consequence of this type of flow, there is a need for investments in techniques and mechanisms that provide the end user with the desired quality and satisfaction in the face of high definition content. This work aims to perform the modeling of video quality loss by analyzing their performance in various resolutions, specifically standards in HD and UHD, at 720p, 1080p and 2160p. In this sense, applying a correlation investigation between the metrics extracted from the videos, using Pearson’s correlation coefficient, and fundamentals of the area in question. Also proposing equations for quality loss modeling, based on analysis of metrics associated with packet loss, in which at the end of the study and according to notes made throughout the text, we used for the general modeling equation, the parameters of Loss of PSNR and Loss of Total Frames. The result obtained shows maximum values of RMSE and Standard Deviation of 0.793 dB and 0.810 dB, respectively, making the developed model very good for the tested video set and its resolutions.

(Universidade Federal do Pará, 2015-09-04) CASTILHO, Jessica Janile Monteiro de; ARAUJO, Jasmine Priscyla Leite de; http://lattes.cnpq.br/4001747699670004; FRANCÊS, Carlos Renato Lisboa; http://lattes.cnpq.br/7458287841862567
The proliferation of mobile devices like smartphones and tablets and the changes of user profile caused the exponentially growth of mobile data traffic. Which leads to an overload of network infrastructure responsible for disposing of this traffic. In order to mitigate or even solve this problem some possibility are presented, one of which is the offloading of traffic cellular networks. For this, two technologies have had greater relevance: Femtocell and WLAN. However, the use of Femtocell has been considered panacea. However there is the alternative of WLAN networks, which has a very large legacy infrastructure. In this sense, this work proposes a comparative study through discrete simulation, aiming to analyze the performance of our networks.

A study was conducted to evaluate the effects of Rosewood oil (RO) on performance, carcass and commercial cut yields and microbiology of the gastrointestinal tract of broiler chickens. Five hundred and forty one-day-old male broiler chicks were arranged in a completely randomized design with six treatments and six repetitions consisting of 15 broiler chicks each. The treatments were: inclusion levels of 0.00mL (0.00EO); 0.15mL (0.15 EO); 0.30mL (0.30 EO); 0.45mL (0.45 EO) and 0.60mL (0.60 EO) of RO/kg diet and control (commercial promoter virginiamycin). At 21 and 40 days old, no significant differences in body weight, feed intake, feed conversion and viability of birds were observed when comparing the controls with the different levels of inclusion of RO. The carcass yields of commercial cuts were not affected by treatments. The increased level of RO reduced the relative weight of the intestines. The broilers consuming growth promoter had the highest concentration of Escherichia coli in the intestinal contents, compared to 0.00 EO and 0.30 EO. It was concluded that, Rosewood oil does affect the performance and yield slaughter, but it does reduce the relative weight of the intestines. RO does not show a consistent antimicrobial activity in vivo against Escherichia coli.
