Relações Públicas: a importância das relações humanas

This monograph has as objective to study the human relations and the Public Relations in the contemporary time in witch the new technologies of the information got closer to the various existent cultures, but who make of the informative society of the global era, the expansion of the capital and of the culture of the more value. Man kind is backing away from the human relations, because the social interactions in the global world are done by objects such as the television, the internet and the telephone in witch cases the subjectivity and the human contact are traded for the informative quantity, because man kind doesn’t have anymore time to think, reflect and to exchange information. Man kind isolates itself and fills it’s subjective emptiness with the products offered by the neoliberal capitalism. The public relations in the organizations seek the human values created from a complex network of social interactions in all the heterogeneous of the organization. Through the communication the public relations tries to manage the relationships with the dialogical communication, between the public-organization, to harmonize the conflicting differences of the organizational environment. Thus, the public relations has to assume the roll of the information manager, and administrator of the human relations in this new global world, informative and that functions from the capital

Sistemas técnicos agrícolas e cafeicultura científica globalizada no sul de Minas Gerais

The study aims to analyze the mechanization of the main coffee growing region in the south of Minas Gerais, in force, especially from the 1970s. But you get new content from the1990s, with the introduction of new information technologies. The use of machines in production processes appear as one of the great transformations of coffee in the period modern after globalization, requiring a labor more specialized, although resulting in unemployment in rural areas. So in the period of globalization new technologies gradually replace manual work. In the coffee farm, the old ways of the production (that handed down from father to son) aren't accepted by the global scientific agriculture (Santos, 2000:88). They are considered inefficient and low quality, but not attendant of patterns the international market. The national companies producing agricultural machines for coffee with emphasis on the company Pinhalense Agricultural Machinery SA believe that the producers of the region are its biggest customers in the country, considering the degree of mechanization more pronounced compared to other coffee growing regions. Analyze the importance of the coffee region with a contribution in the indicators of export and trade surplus in the Brazil and State of Minas Gerais

Comunicação interna e gestão de pessoas: um olhar para as relações humanas nas organizações

The main purpose of this study is to show how internal communication can be allied to people management in the process of transformation of the organizations. It is known that the advent of new technologies and the information age, consequences of globalization, are provoking deep transformations in organizations and reaching people too. This way there is the human and the social issue that goes beyond the race for profit. The new forms of management are becoming increasingly concerned with the value of human being and communication professionals, more specifically public relations, can facilitate processes and significantly improve the relationships towards positive results

A matemática no ciberespaço: um olhar fenomenológico para a expressão dos sujeitos

With the implementation of new technologies on the world stage of communication, Internet access has become increasingly numerous. Being sought by this means all kinds of information, from knowledge to entertainment. This paper intends to report the experience in two communities of the Internet, particularly in the social network Orkut, entitled I Hate Mathematics and I Love Mathematics, whose members are students, teachers and people who want to express how they feel about mathematics. The goal is to understand what took the members of these communities to hate or love Mathematics, clarifying the nature of the network Orkut and its contribution to mathematics education. For the analysis of data from field work, we use the phenomenological approach. The procedures followed by such approach allowed us to build four open categories: Research and Background, revealing that the research activities allow students to develop strategies, develop creativity and shows that what is learned in classroom is not just an accumulation of knowledge; Teacher's Role shows that it is necessary that the teacher understands the meaning of being a teacher and worry about being a student; Acquisition Technique, it is necessary that students be able to understand what is done and how it is done, and Sense of What is Done, to do is not directly linked to comprehend. The interpretation of these categories helped us understand the investigated giving us source to analyze how Information and Communication Technologies (ICT) can help the teacher understand the student's relationship with Mathematics

O artista plástico e seus públicos na perspectiva da assessoria de relações públicas

This work aims to study and see the importance of building the image and reputation of the artist through a publishing of public relations, public recital, new technologies, media, cultural production and curatorial work. To this, we analyzed the history of the profession of public relations in Brazil. As well as their concepts, practices and definitions. Focus on work of publicist and cultural production sectors. The choice of theme is done by the need to understand the relationships. That intertwines in the art market and what media that best reaches in their audiences. Considering the artist-consumer relationship, and the relationship brand-artist and artist-public. And so, the importance of this advice means less explored public relations, for the creation of the brand concept for the artist before his public. Considered in this work as a gallery, art dealer, curator, media and consumers. In this context an analysis is done on diverse views on the market of the arts through specific interview. This interviews was made with professionals working in the cultural sector. And help to understand the communication segments that exist and the current conditions of the market in the context of competitiveness. As was considered the academic education of the public relations professional, it geared to the cultural context, the interviews with professional future. And then was considered that public relations presents itself as a proposal for better communication in the arts. They are concern to create concepts of brand identity-thinking artist and the best means for the artist to be present in this area

Relações Eficazes: a importância da comunicação eficaz nas organizações

This project aims to study and verify the importance of effective communication in contemporary organizations, considering current factors such as globalization, new technologies and market competition that make companies be always updated. The choice of the theme is due to the necessity to know that it is important to have an integrated communication between the employees and the customers, so that the established functions in the organizations occur positively. In this context, we present the concept of management, communication and organizational culture, focusing on the integration of business communication. The importance of the employee was also a focus of the study, involving the positioning of organizations. In this context, the case study is placed, considering that companies are characterized by carefully reading the feedback and reformulating the communication, making it effective as “Grendene” has done. Opposing to those ideas is “Terra” company. Thus, the project defends the importance to work on the communication, so that it becomes effective. During the project ways and means to manage communication are shown, so that it recognizes this need and become efficient, benefiting organizations and their audiences

Estudo acústico da variação da frase interrogativa, com destaque para o dialeto paulista

With the new computational technology, the studies of acoustic phonetics started to have a special place. This brought a new way of seeing the phenomenon and to deal with it in the phonetics and in the phonology. Such studies have been developing even more, recently, with a facilitated use of computational programs specially developed to the acoustic analysis of speech, such as PRAAT. Programs like this have been very interesting and useful recently. The acoustic models of analysis have influenced the way the researchers came to see and to interpret the prosodic phenomenon. The current project investigates the acoustic production of declarative and interrogative sentences from the “paulista” Portuguese. This study contributes for a more detailed description of the phenomenon, also becoming inserted in the chart of “intonational” descriptions of the Brazilian Portuguese. The subject of this current project is the acoustic study of some intonation aspects from the speaking Portuguese in Brazil, with a special place to the “paulista” dialect. The current project´s purpose is to make a specific study of interrogatives sentences through the acoustic data analysis of “paulista” dialect speakers

Influência da luz LED na cultura celular de Mieloma múltiplo murino–NS1 in vitro

A monoclonal antibody (mAb) is an important tool in medical biotechnology and the production of biopharmaceuticals, especially for disease diagnosis and treatment of infections, because the antibodies have a significant advantage over chemical agents used in conventional therapies . The last thirty years the technology of production of monoclonal antibodies developed mainly the technique of obtaining in vitro, but also of their production is laborious, the cost is high. A major element of the high cost of production is the fact that the long-term culture consumes a large amount of imported inputs with high added value. A major contribution of this work is to promote cell growth more quickly and efficiently. Currently, a great race to discover new technologies and techniques to synthesize new antibodies and significantly increase the production of murine mAbs. New technologies such as laser and LED are innovations and widespread in modern life, so much so that its use has proliferated worldwide, primarily in the medical field. Recent studies show a series of results from the influence of the LED light in biological tissues such as: increasing the rate of cell proliferation, increased production rate of fibroblasts, increasing the rate of synthesis of RNA and DNA synthesis of ATP, etc. To assess the contribution of the LED in the culture of Myeloma NS1murino compared to the standard procedure. - NS1 cells were provided and followed the criteria of culture medium of the Laboratory of Cellular Engineering Center of Botucatu (POPs).

Falência renal aguda em pequenos animais

The pets, mostly dogs and cats are susceptible to a variety of situations that can lead to acute kidney failure, such as infection and intoxication, besides other common causes such as dehydration or other pre-existing diseases. The abrupt decrease in renal function in these animals characterizes a severe clinical condition and requires specialized veterinary medical care since it increases the death. Early diagnosis is an important factor for the survival of these animals and so is the appropriate treatment. New technologies on diagnosis and treatment of serious diseases in veterinary medicine have made acute renal failure successfully reversed by hemodialysis in cases where conventional therapy may not be effective. In cases like that, hemodialysis treatment may be the only chance of survival for the animals, which makes this therapy more and more important and necessary, especially in referral centers of veterinary assistance

Considerações gerais sobre os resíduos eletrônicos

As new technologies improve, people’s lives gain in comfort and accessibility. However, along with these technologies comes a growth in “soon to fall into disuse” product consume, either because they have reached the end of their life cycle, or because they were substituted by newer and more advanced models. These electronic wastes are still with no certain destination, and could be donated to welfare companies, but the majority is thrown in wide open dumping grounds or landfills, where they can contaminate water and soil with their toxic components. This work seeks to evaluate the e-waste concept, their impacts in the environment and human life, as well as the current national and international e-waste management and destination, finally reflecting on international decisions that would be appropriate for the Brazilian system.

As atividades experimentais no ensino de física

This work was developed from a literature search in order to provide teachers of physics theoretical and methodological requirements for the use of experimentation in physics teaching, with the aim of contributing to the teaching practice of these teachers and, consequently, for improving teaching this discipline. Therefore, to deal in the course of this research, the goals and types of practical activities, new information and communication technologies that fit the experimental approaches and the role of the teacher in this context, specifying the variables that influence and relate with experimental activities. Studies are presented on the methodology and planning of experimental activities to draw attention to the teacher and the important issues relevant to the preparation of these activities as, for example, the proposed objectives and types of discourse and existing approaches for the conduct of practical activities. In this sense, the trend is highlighted for walks where the approach of practical activities, within the context of practices interactionist and are pointed out strengths and weaknesses of different types of activities presented. We also highlight aspects of the learning process associated with some theoretical reference that are on that subject, as Piaget, Vigotski and Ausubel, so that the teacher can apply the concepts in their theories worked in the practical lessons of physics

Processamento do compósito de fibra de capim-sapê / epóxi e avaliação da resistência à flexão “t” de Student

In recent years a great worldwide interest has arisen for the development of new technologies that enable the use of products with less environmental impact. The replacement of synthetic fiber plants is a possibility very important because this fiber is renewable, biodegradable and few cost and cause less environmental impact. Given the above, this work proposes to develop polymeric composites of epoxy resin and study the behavior of these materials. Both, the epoxy resin used as matrix in the manufacture of sapegrass fiber composite, as tree composites formed by: epoxy/unidirectional sapegrass long fiber, 75% epoxy/25% short fiber, by volume, and 80% epoxy/20% short fiber, by volume, were characterized by bending, and the composites produced with short fibers random were inspected by Optical Microscopy and Acoustics Inspection (C-Scan). For the analysis of the sapegrass fiber morphology, composites 75% epoxy/25% short fiber (sheet chopped) and 80% epoxy/20% short fiber images were obtained by optical microscope and the adhesion between polymer/fiber was visualized. As results, the flexural strength of composites epoxy/unidirectional long fibers, 75% epoxy/25% short fiber and 80% epoxy/20% short fiber were 70.36 MPa, 21.26 MPa, 25.07 MPa, respectively. Being that composite showed that the best results was made up of long fibers, because it had a value of higher flexural strength than other composites analyzed
