Design de Relações entre tecnologias amigáveis e sociabilidades virtuais: um novo campo de investigação para o Design

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

A utilização das tecnologias assistidas por computador como elemento de integração, pesquisa e desenvolvimento nas disciplinas de projeto para a engenharia e design

The use of technologies called computedassisted, such as CAD - (Computed Aided Design), CAM - (Computed Aided Manufacturing) and CNC - (Computed Numerical Control), increasingly demanded by the market, are needed in the teaching of subjects technical drawing and design courses for engineering and design. However its use findl barriers in the more conservative wing of the academy, who advocate the use of traditional drawing, for the settling of the concepts and the development of spatial reasoning. This study aimed to show the results obtained with the design and production of an apparatus for measuring a three-dimensional computer-aided milling machine, interaction, integration and consolidation of concepts, fully demonstrating that the learning of computer-assisted technology is possible, and its use is most appropriate, meaningful and productive, than the use of instruments in the classic design.

O design inserido no vestuário infantil: um estudo sobre as roupas com conceitos lúdicos de aprendizagem

Among the current trends for children’s clothing is clothing that may contribute to the development and children’s learning through interaction with their clothes. For child interaction / clothes from occurring, this dress is appropriate the knowledge of design, which assist in its construction. Thus, this study seeks to investigate design principles that can be adopted for production of clothing that can assist in the development of children, showing how notions of education can be incorporated into costumes, studying the relationships and interactions between design, fashion and education. The study addresses this garment from the perspective of design, so as to provide insights that could contribute to the creation of the pieces. To that end, we developed a theoretical framework that sought to show the infant universe, communication, clothing and design. According to the methodological procedures for the work, there was a case study in ten private schools in Bauru-sp in order to obtain data on experiences with children about their preferences, attitudes and ways of reasoning child’s world.

The aim of this paper was to establish parameters for the creation and management of Digital Learning Objects.

Design e inovação em contexto de ensino-aprendizagem

This paper presents part of the results of a post-doctoral research project which is called "Hypermedia Design involved with the User Experience". The discussion will be undertaken in this article assumes that the use of a hypermedia environment facing the field of Design can facilitate the process of teaching and learning in an undergraduate degree in Design. The theme that guides the paper of the following question: if the education and training in design does not allow access, involvement and knowledge of the technologies in its primary base that practitioners and researchers are forming for the near future? For both this study focuses on the use of a digital environment by reporting of an experiment of using hypermedia digital book "Design, Education and Technology" as a teaching tool in undergraduate courses in design, results and notes on issues involving interactivity and user experience. The methodology has a qualitative bias, developed along the lines of exploratory research in the form of a case study, lectures, and workshops for the dynamic observation, a questionnaire and analysis of results were applied

An introductory informatics theoretical framework, based on an integrable lattice model using quantized function algebras, for studying DNA-ionized gas interaction system

Usually we observe that Bio-physical systems or Bio-chemical systems are many a time based on nanoscale phenomenon in different host environments, which involve many particles can often not be solved explicitly. Instead a physicist, biologist or a chemist has to rely either on approximate or numerical methods. For a certain type of systems, called integrable in nature, there exist particular mathematical structures and symmetries which facilitate the exact and explicit description. Most integrable systems, we come across are low-dimensional, for instance, a one-dimensional chain of coupled atoms in DNA molecular system with a particular direction or exist as a vector in the environment. This theoretical research paper aims at bringing one of the pioneering ‘Reaction-Diffusion’ aspects of the DNA-plasma material system based on an integrable lattice model approach utilizing quantized functional algebras, to disseminate the new developments, initiate novel computational and design paradigms.

EROSION LOSSES FROM RUNOFF: INTERACTION OF SOIL COVER AND EROSION CONTROL PRACTICE

The flow of sediment from cropped land is the main pollutant of water sources in rural areas. Due to this fact, it is necessary to develop and implement technologies that will reduce water and sediment discharges. Accordingly, an experiment was conducted in the Department of Biosystems Engineering - ESALQ / USP, Piracicaba - SP with the objective to evaluate the effect of different soil cover (bean, grass and bare ground) and erosion control practices (wide base terraces and infiltration furrows in slopes (no practices to control erosion)) while measuring water losses in runoff. The statistical design adopted was randomized blocks in a 3x3 factorial scheme resulting in 9 treatments with 3 replicates (blocks). The period of rainfall data collection was December 6, 2007 to April 11, 2008. A 21.1 cm diameter rain gauge was installed in the experimental area. Terraces were the most efficient practices for reducing erosion losses in the treatments with infiltration furrows being better than the control treatment. Bean was more effective than grass in reducing erosion. Bare ground was the least efficient.

Influence of temperature, light and nutrients on the growth rates of the macroalga Gracilaria domingensis in synthetic seawater using experimental design

In the present study, the daily relative growth rates (DRGR, in percent per day) of the red macroalga Gracilaria domingensis in synthetic seawater was investigated for the combined influence of five factors, i.e., light (L), temperature (T), nitrate (N), phosphate (P), and molybdate (M), using a statistical design method. The ranges of the experimental cultivation conditions were T, 18-26A degrees C; L, 74-162 mu mol photons m(-2) s(-1); N, 40-80 mu mol L-1; P, 8-16 mu mol L-1; and M, 1-5 nmol L-1. The optimal conditions, which resulted in a maximum growth rate of a parts per thousand yen6.4% d(-1) from 7 to 10 days of cultivation, were determined by analysis of variance (ANOVA) multivariate factorial analysis (with a 2(5) full factorial design) to be L, 74 mu mol photons m(-2) s(-1); T, 26A degrees C; N, 80 mu mol L-1; P, 8 mu mol L-1; and M, 1 nmol L-1. In additional, these growth rate values are close to the growth rate values in natural medium (von Stosch medium), i.e., 6.5-7.0% d(-1). The results analyzed by the ANOVA indicate that the factors N and T are highly significant linear terms, X (L), (alpha = 0.05). On the other hand, the only significant quadratic term (X (Q)) was that for L. Statistically significant interactions between two different factors were found between T vs. L and N vs. T. Finally, a two-way (linear/quadratic interaction) model provided a quite reasonable correlation between the experimental and predicted DRGR values (R (adjusted) (2) = 0.9540).

Strategies in identifying individuals in a segregant population of common bean and implications of genotype x environment interaction in the success of selection

The objective of this study was to compare the BLUP selection method with different selection strategies in F-2:4 and assess the efficiency of this method on the early choice of the best common bean (Phaseolus vulgaris) lines. Fifty-one F-2:4 progenies were produced from a cross between the CVIII8511 x RP-26 lines. A randomized block design was used with 20 replications and one-plant field plots. Character data on plant architecture and grain yield were obtained and then the sum of the standardized variables was estimated for simultaneous selection of both traits. Analysis was carried out by mixed models (BLUP) and the least squares method to compare different selection strategies, like mass selection, stratified mass selection and between and within progeny selection. The progenies selected by BLUP were assessed in advanced generations, always selecting the greatest and smallest sum of the standardized variables. Analyses by the least squares method and BLUP procedure ranked the progenies in the same way. The coincidence of the individuals identified by BLUP and between and within progeny selection was high and of the greatest magnitude when BLUP was compared with mass selection. Although BLUP is the best estimator of genotypic value, its efficiency in the response to long term selection is not different from any of the other methods, because it is also unable to predict the future effect of the progenies x environments interaction. It was inferred that selection success will always depend on the most accurate possible progeny assessment and using alternatives to reduce the progenies x environments interaction effect.
