Semantikos: proposta de interfaces para aplicativo mediador de técnica de diferencial semântico em mobile tablet

This research aims to systematize a proposal of developing a mobile tablet application in order to help implementing the Semantic Differential technique – SD, under the approach of Participatory Design. In 1975, Osgood et al. created the Semantic Differential technique. Since then, many experiments use it to measure the affective perception of individuals concerning objects and concepts by means of compounded scales of bipolar adjectives, based on the theoretical models that support the technique: the conductible, spatial and metric models. During the application of the technique with potential users, the researcher must simultaneously manage several contexts, that is, audio recorder, when authorized, and observe and record spontaneous reports of the respondent. It is noticeable that often occurs a cognitive overload during this event. Thus, the use of a single application whose interface is assigned to its users and respondents could assist researchers in applying the SD technique. This research aimed to understand the processes inherent to the task of implementing the Semantic Differential technique and obeyed the following steps: a) training of users, b) background questionnaire c) interview with Focus Group, and d) cooperative evaluation. Besides these procedures, one can also observe the degrees of facilitation or difficulty concerning the use of the conventional model, which is the development and application of scales with the aid of printed material, pencil, pens, clipboards, and recorder software for editing the document and data analysis. This paper comprises reactions and impressions from the experiences of users of SD technique. Considering the data recollected from the user’s observation, the hypothesis of the experiment proved to be right. It means that the development of the application for mobile tablet employing the technique of Semantic Differential is viable, since it assembles all the steps in one only tool, increases the accomplishment of the task between user/researcher and user/respondent resulting in their mutual satisfaction.

Explorando a execução de técnicas estendidas no oboé encontradas em quatro peças contemporâneas

This dissertation presents an investigation of the evolutionary process of extended oboe techniques, through literary analysis and practical research. The objective of this work is to provide assistance to oboists interested in learning these techniques. Additionally, this work encourages the student, through the process of experimentation, to explore the questions that may arise around the aesthetics of sound, the concept of gesture as an additional visual and aural element in music, and the collaboration and “real-time” creation processes. Discussed within the work, are the relationship between the instrument (the oboe) and extended techniques, and two possible definitions of extended techniques, provided by Luk Vaes (2009) and Gardner Read (1993). Also explored are the how and why some composers have utilized extended techniques in their compositions, including brief discussions relating to extended techniques in real-time composition (improvisation), extended techniques and technological resources, theatrical gesture as an extended technique, and suggestions of how musicians might approach theatrical gestures in performance. Four works were visited: “I Know This Room So Well” – Lisa Bielawa (2007-9); “Four Pieces for Oboe and Piano” – Ernst Krenek (1966); “In Freundschaft” – Karlheinz Stockhausen (1978); “Atem” – Mauricio Kagel (1969-70); and an exploration of the difficulties and solutions associated with each extended technique found within these pieces, was carried out. The following founding works on extended oboe techniques were used, as a basis for research: books - Heinz Holliger’s Pro Musica Nova (1972); Gardner Read’s Compendium of Modern Instrumental Techniques (1993); Peter Veale & Claus-Steffen Mahnkopf’s The Techniques of Oboe Playing (1994); and Libby Van Cleve’s Oboe Unbound: Contemporary Techniques (2004); and articles - Nora Post’s “Monophonic sound resources for the oboe: Part I – Timbre” (1984), “Part II- Pitch and other techniques” (1984), and “Multiphonics for the oboe” (1982).

"Cantata para louvor e glória", de Cleide Dorta Benjamim: preparo para a execução

This study aims to document the preparation process for the implementation of "Cantata To Praise and Glory"(Cantata Para Louvor e Glória), composed in 1985 by composer Cleide Dorta Benjamin (1936 - ), in order to anticipate and address the possible difficulties faced by future conductors, singers and instrumentalists. Issues that relate to the chosen text as well as its structure and importance in the compositional process, are initially addressed through a brief presentation of the work. Consequently, by addressing every detail of the work, solutions to vocal and instrumental execution difficulties, as well as with the conducting gesture, are analyzed, identified and proposed. The work also presents a report that describes all the practical processes of preparation of the Cantata: reissue of the score; selection and profile of singers and instrumentalists; rehearsals; changes and adjustments to the score; and a brief interview with four singers and two musicians who participated in the process. The interaction with the composer throughout a significant part of the work, brings a notable increase of possible clarifications and idea development, enabling a coherent performance of the work.

Usabilidade da Interface do Sistema Eletrônico de Editoração de Revistas: um estudo da revista BiblioCanto da UFRN

The electronic journals correspond publishing channels and dissemination of scientific information. Through them, users can spread their studies as well as developing new researches. One of the systems used for creation and e-journals management is the Electronic System for Journal Publishing (SEER), used in the construction of periodic portals, as well as the creation of magazines in isolation. In this purport, it is believed that the management systems and creation of e-journals should be developed (internally and externally) according to the needs of its users. In the case of internal development, some of these processes refer to the copyright registration and submission of articles, which, in turn, are relevant tasks in the editorial process. Thus, the proposed study, thematic Usability of scientific journals, aims to analyze the usability of the copyright registration process and submission of articles in the Electronic System for Journal Publishing through BiblioCanto magazine, part of the Electronic Journals Portal of the Federal University of Rio Grande do Norte (UFRN). For the realization of the research, two valuation techniques were used: the Usability Test with a total of twenty participants and the Cooperative Evaluation, with the same number of participants separated in four categories considered target audience of that magazine, namely: undergraduate students, graduate students, teachers and librarians. The results indicated that the two analyzed processes (copyright registration and submission of articles) need improvement. In the case of the registration process, the following needs are: signalizing of the conducting registration ambient; description and exclusion of requested information on the registration form. In the process of article submission, it is emphasized improvement of aspects: the early steps to submission, signaling of required fields, concise description of the steps, minimization and review of the steps. To this end, it is believed that in general idea the SEER partially meets the needs of its users regarding the usability of such software.

Sustentabilidade de empreendimentos econômicos solidários: contribuições e desafios do PITCPES/UFPA a partir da análise da Cooperativa dos Fruticultores de Abaetetuba - COFRUTA

The study aimed to understand how the methodology of hatching contributes to the sustainability of economic enterprises in solidarity. For analysis, we developed a study on the social economy and the incubation methodology, based on the program of teaching, research and extension - Technological Incubator of Popular Cooperatives and Entrepreneurship Solidarity (PITCPES), and as the survey of the Cooperative of Fruit of Abaetetuba - COFRUTA. We started from the exploratory-descriptive approach in a qualitative and quantitative, in order to demonstrate the process of sustainability under the dimensions of different kinds such as: the economic dimension, social dimension, the political dimension, size and scale management training. Based on the analysis of these different dimensions was reached results as: first the recognition that the incubator contributes to the sustainability of COFRUTA, especially with regard to planning, control and the need to diversify production. However, there was suggestion of cooperative for training and technical assistance is continued, to the extent that the performance of projects under the base leaves gaps for the learning and application of social technologies required to the Incubator. It also concluded that the dissertation contributes to the team of the incubator can assess their strengths and weaknesses in their performance

Gestão híbrida em cooperativa de crédito: uma análise a partir do interesse, participação, satisfação e expectativa dos cooperados da COOPERUFPA

The globalization of markets has confirmed for the processes of change in organizations both in structure and in management. This dynamic was also observed in credit unions because they are financial institutions and are under the rules of the Brazil´s Financial System. Given the context of organizational changes in the financial capital has played the traditional management reform is urgent. In organizations credit unions, given its dual purpose, because in the same organizational environment and capitalism coexist cooperative whose logics are antagonistic, but can live through the balance between instrumental rationality and substantive rationality in credit unions. Based on this concept a new form of management should be thought to be able to accommodate the demand of cooperative, community, government and the market. Hybridization has been observed in management practices` COOPERUFPA into dimensions financial, social and solidarity participation with a trend in paradigmatic form of hybrid management, in that it directly or indirectly affect the management decisions in the credit union. The hybrid management is a trend that has been setting the basis for societal transformation, so that credit unions promote actions of welfare oriented cooperative members and the community around the same time that attend the dynamics of market globalization. These actions, in the context of hybrid management should be implemented by COOPERUFPA from the sociability of the remains and the wide diffusion of solidarity culture between cooperative partnership as a way to recover their participation in trade relations, financial and the social collective developement. For the members of COOPERUFPA financial interest is evidenced in greater relevance for the social interest given its dominant relationship as "mere customer" of the credit union, however, the proactive participation of the life of the cooperative credit union is one of its expectative among of participation of to share power in decisions by general meetings. This passivity`s cooperator of the COOPERUFPA in defending the ideals overshadowed the spread of cooperative principles and values of cooperation among them. Thus his conception for COOPERUFPA in the financial dimension, social and solidarity democracy, performed transversely. The COOPERUFPA for not developing an education policy for the cooperation among its members, contributed to a process of collective alienation of cooperative ideals, since the cooperative do not understand the reality that surrounds them as members of an organization whose mission is to social and financial sustainability of its members

Cooperativa habitacional autofinanciável :uma alternativa de mercado à escassez de financiamento

As an example of what happened in Brazil in the 90s, it s noticed in Natal a new system of cooperative housing production which is done by advancing the users resources selffinancing. This system comes as an alternative for the real state market performance since the end of the National Housing Bank (BNH), in 1986. Self-financed housing cooperatives play an important social role by contributing to own housing acquisition by low-income population, without, however, becoming a mechanism of social interest housing production. It is important to consider that Brazil registers a housing deficit of 6.6 million housing units (IBGE 2000/Census), which, compared to 1991, shows an increment of 21.7% to a growth rate of 2.2% a year. This deficit figure has been deepening, mainly with the end of the National Housing Bank (BNH). The self-financed cooperative housing production broadens around the Metropolitan Region of Natal (RMN) and remains as an alternative to the lack of financing in the housing / real state market. In general, the aim of this work is to analyze the role of self-financing housing cooperatives on the housing production in the RMN, in order to identify their role in the real state market, in the own housing promotion and in the housing policy. The Universe of this study is performance of four housing cooperatives - CHAF-RN, COOPHAB-RN, MULTHCOOP e CNH - that work through self-financing. It is considered here an amount of 38 undertakings launched between 1993 and 2002, including 8143 housing units. The methodology adopted consists of bibliographic, documental and field research. As a result, actions like brokerage, marketing, speculation, and the criteria to define places for undertakings and final products, show how close they are to the housing market production. As a matter of fact, this short distance explains why the self-financed cooperative production for social interest housing is still limited. This reinforces the theory that it is necessary to define and implement a subsidized housing policy to serve the low-income Brazilian population

Simulador de dano à formação, aplicado ao Projeto e à execução da perfuração de poços de petróleo

With the high oil price variability, the petroleum and the reservoir engineers are usually face to face on how they can evaluate the well performance and productivity. They can improve high productivity from the well construction to the secondary recoveries, but they have never tried a measurement in the drilling operations about the lower productivity index. As a rule, frequently the drilling operations hear from the reservoir engineering and geology that, if there is a formation damage, probably some drilling operations practices were not done properly or the good practice in petroleum engineering or mud engineering were not observed. The study in this working search is an attempt of how to measure a formation damage just from the project drilling to the drilling operations, with datum from the fields in Brazilian northeast and putting into practice a Simulator developed from the modeling on the theory offered by different experts and sources in formation damage
