Torrenting values, feelings and thoughts : cyber nursing and virtual self care in a breast augmentation forum

Earlier research shows that breast augmentation is positively correlated with positive psychological states. The aim of this study was to explore the shared values, feelings, and thoughts within the culture of breast enlargement among women visiting Internet-based forums when considering and/or undergoing esthetic plastic surgery. The study used a netnographic method for gathering and analyzing data. The findings show that the women used the Internet forum to provide emotional support to other women. Through electronic postings, they cared for and nursed each others’ anxiety and feelings throughout the whole process. Apart from the process, another central issue was that the women's relationships were frequently discussed; specifically their relationship to themselves, their environment, and with the surgeons. The findings suggest that Internet forums represent a channel through which posters can share values, feelings, and thoughts from the position of an agent of action as well as from a position as the object of action. These dual positions and the medium endow the women with a virtual nursing competence that would otherwise be unavailable. By introducing the concept of torrenting as a means of sharing important self-care information, the authors provide a concept that can be further explored in relation to post modern self-care strategies within contemporary nursing theories and practice.

Teaching Intercultural Communication in Foreign Language Education through Video Conferencing

Since 1980s, Western linguists and specialists on second language acquisition have emphasized the importance of enhancing students’ intercultural communication competence in foreign language education. At the same time, the demand for intercultural communicative competence increased along with the advances of communication technology with its increasingly global reach and the process of globalization itself.In the field of distance language education, these changes have resulted in a shift of focus from the production and distribution of learning materials towards communication and learning as a social process, facilitated by various internet-based platforms. The current focus on learners interacting and communicating synchronously trough videoconferencing is known as the fourth generation of distance language education. Despite the fact that teaching of Chinese as a foreign language (CFL) faces the same or even greater challenges as teaching other languages, the intercultural communication perspective is still quite a new trend in CFL and its implementation and evaluation are still under development. Moreover, the advocates of the new trends in CFL have so far focused almost exclusively on classroom-based courses, neglecting the distance mode of CFL and leaving it as an open field for others to explore. In this under-researched context, Dalarna University (Sweden), where I currently work, started to provide web-based courses of the Chinese language in 2007. Since 2010, the Chinese language courses have been available only in the distance form, using the same teaching materials as the previous campus-based courses. The textbooks used in both settings basically followed the functional nationalism approach. However, in order to catch up with the main trend of foreign-language education, we felt a need to implement the cross-cultural dimension into the distance courses as well. Therefore in 2010, a pilot study has been carried out to explore opportunities and challenges for implementing a cross-cultural perspective into existing courses and evaluating the effectiveness of this implementation based on the feedback of the students and on the experience of the teacher/researcher.

Increase in severity of molar-incisor hypomineralization and its relationship with the colour of enamel opacity: a prospective cohort study

Background. Predicting risk of posteruptive enamel breakdown (PEB) of molar-incisor hypomineralization (MIH) opacity is a difficult but important clinical task. Therefore, there is a need to evaluate these aspects through longitudinal studies.Objective. The aim of this longitudinal study was to analyse the relationship between colours of MIH opacity of children aged 6-12 (baseline) and other clinical and demographic variables involved in the increase in severity of MIH.Materials and methods. A blinded prospective 18-month follow-up was conducted with 147 individuals presenting mild MIH. Tooth-based incidence of increase in severity of MIH (PEB or atypical restorations) was used as dependent measurement. Enamel opacities were recorded according to colour shades of white, yellow and brown, allowing assessment of susceptibility to structural loss over time, according to colour of MIH opacity. Poisson regression models were used to adjust the results for demographic and clinical variables.Results. Brown and yellow MIH opacities were at higher risk for PEB and atypical restorations than those of white ones, even after adjustment for clinical and demographic variables.Conclusion. Teeth presenting mild MIH severity associated with yellow and brown enamel opacities were at high risk for increase in severity of MIH than lighter ones. This result could help clinicians determine a risk-based treatment for children with MIH.

Vase Life of New Tropical Cut Foliage: Cordyline terminalis

Cordyline terminalis is a tropical ornamental with high decorative value due its variety of colors and foliar patterns. This ornamental is new in the Brazilian market and has large potential to be exported. The lack of studies on postharvest aspects is a problem for new crops, and the development of good post-production techniques can reduce costs due to loss of unsalable, damaged plants. The present work aimed to characterize the vase life of red and green cultivars of C. terminalis. Conservation techniques, such as pulsing with gibberellic acid (GA(3)), wax spray, and cold storage for 10 and 20 days at 5, 10, and 13 degrees C were tested. Also, macro-and micronutrients concentration was tracked during the senescence process. In the water-based treatment (control), both cultivars had a vase life of 21 days. Vase life was not influenced by wax spray, GA pulsing, or cold storage for 10 days at 5, 10 or 13 degrees C. In both cultivars, the postharvest techniques used did not improve the vase life on this species. on the other hand, by cold storing the foliage for 20 days in any of the tested temperatures, the vase life was shortened one week, with a total of 14 days longevity compared with all other treatments. Color changes were not correlated with senescence of the foliage. Nutrients did not change during the evaluation period. C. terminalis had a vase life long enough for export, supported by cold storage up to 10 days, which did not shorten the vase life.

Motivações em competição na variação sociolinguística: o plural dos predicativos na variedade de São José de Rio Preto

O objetivo deste trabalho é o de submeter a um tratamento variacionista, de base quantitativa, dados de marcação variável de plural no SN e no SA em contexto de predicativo, obtidos em córpus coletado na região de São José do Rio Preto. O trabalho procura examinar se a marcação de pluralidade nos predicativos pode ser explicada com base em motivações exclusivamente formais, ou exclusivamente funcionais, ou ainda, com base na interação entre ambas, que consistiriam, assim, em motivações em competição. Os resultados indicam que nem as motivações funcionais, nem as motivações formais regem solitariamente o fenômeno, que aparece fortemente condicionado por uma restrição externa específica, o grau de escolaridade. Por essa razão, a explicação mais plausível para a marcação de pluralidade nos predicativos é a de que há motivações em competição, nos termos de Du Bois (1985), e é a marcação de pluralidade o bem limitado, pelo qual forças múltiplas, as motivações formais ou internas e funcionais ou externas, competem entre si.

Ozone therapy in medicine and dentistry

Aim: The purpose of this review is to present the potential for the incorporation of ozone therapy into the practice of dentistry. Background: Ozone gas has a high oxidation potential and is 1.5 times greater than chloride when used as an antimicrobial agent against bacteria, viruses, fungi, and protozoa. It also has the capacity to stimulate blood circulation and the immune response. Such features justify the current interest in its application in medicine and dentistry and have been indicated for the treatment of 260 different pathologies. It can be used for the treatment of alveolitis as a replacement for antibiotic therapy, as a mouthwash for reducing the oral microflora, as well as the adherence of microorganisms to tooth surfaces. Ozone has been shown to stimulate remineralization of recent caries-affected teeth after a period of about six to eight weeks. Conclusion: The future of ozone therapy must focus on the establishment of safe and well-defined parameters in accordance with randomized, controlled trials to determine the precise indications and guidelines in order to treat various medical and dental pathologies. Scientific support, as suggested by demonstrated studies, for ozone therapy presents a potential for an atraumatic, biologically-based treatment for conditions encountered in dental practice.

O ensino de oncologia em enfermagem: um panorama do Brasil, Estados Unidos e outros países

The incidence of neoplasias has increased worldwide every year, and the training of qualified nurses for quality care provision to oncologic patients is necessary. This study aimed at identifying, in the literature, how oncology has been taught in the curricula of several undergraduate nursing programs in Brazil, the United States and other countries. The articles were located on Internet-based databases, namwly Lilacs and Scopus, from which 35 publications were found, and 18 articles were included. In Brazil, oncology is taught in undergraduate nursing programs in an isolated and punctual fashion, and it is not included in curricula. Parallelly, in the other countries included in the study, similarity was found as to this aspect; however, there is evidence of the implantation of elective and extracurricular courses. It is noteworthy that, in Brazil, there is evidence of government policies for oncology teaching and cancer control; nevertheless, such guidelines have not been concretized in curricula. The study showed a scenario in which oncology teaching in undergraduate nursing programs is insufficient or inexistent both in Brazil and in other countries, which compromises the training of future qualified professionals that will be attentive to that theme, since cancer is a frequent pathology, and the presence of nurses is fundamental for the care of such patients from diagnosis to cure, or even during occasional death

Avaliação da eficácia dos biocurativos em ratos wistar com lesões de pele causadas por queimaduras

Accidents caused by thermal, chemical, electrical or radioactive agents cause skin lesions causing burns of varying degrees. The therapeutic approach aims to restore damaged tissues and involves a wide range of products on the market. This study aims to evaluate the use of biological dressing, biotech product developed at the Blood Center of Botucatu / UNESP obtained from fresh frozen plasma or platelet concentrate with in vitro addition of thrombin and calcium gluconate. This addition in the platelet concentrate, intended to release the active growth factors of the platelets granules on the healing process. The study of the effectiveness of Platelet Gel home made in Wistar rats was established, in agreement with scald burns, comparing efficacy and cost of Platelet Gel with usual hospital -based treatment collagenase + chloramphenicol plus cost analysis through pharmacoeconomics. We used 25 Wistar rats were divided into 3 treatment groups: Group A, Collagenase + Chloramphenicol; Group B, Platelet Gel and C, control. The products were applied every other day for 30 days in animals. In group A, there was the presence of erythema and crust in all animals. The exudates was indentified 2/10 animals. For the Group B, we observed the presence of erythema and crust at all and no presence of exudates. In group C all the animals showed erythema with no presence of exudates and scab occurred in 1/10. Statistical analysis showed significant difference ( p < 0.0 ) for crust formation between Groups B and C. In the histological analysis, group A showed a slight amount of blood vessels and collagen fibers, moderate amounts of macrophages and fibroblasts was observed while B and C groups showed moderate amounts of blood vessels, macrophages and fibroblasts and discreet presence of collagen fibers. The re-epithelialization occurred in most animals of all groups without significant statistical differences. For the aspects of pharmacoeconomics, the platelet gel presented a better cost - effectiveness in relation to treatment based on collagenase / chloramphenicol. In light of the ethical aspects of the raw material is the result of spontaneous blood donation, the proposal should have biological dressings productions the responsibility of public blood transfusion centers for free distribution. This may point to the production chain of Brazilian blood banks like special blood components for use no intravenous.

Research Blogging: Indexing and Registering the Change in Science 2.0

Increasing public interest in science information in a digital and 2.0 science era promotes a dramatically, rapid and deep change in science itself. The emergence and expansion of new technologies and internet-based tools is leading to new means to improve scientific methodology and communication, assessment, promotion and certification. It allows methods of acquisition, manipulation and storage, generating vast quantities of data that can further facilitate the research process. It also improves access to scientific results through information sharing and discussion. Content previously restricted only to specialists is now available to a wider audience. This context requires new management systems to make scientific knowledge more accessible and useable, including new measures to evaluate the reach of scientific information. The new science and research quality measures are strongly related to the new online technologies and services based in social media. Tools such as blogs, social bookmarks and online reference managers, Twitter and others offer alternative, transparent and more comprehensive information about the active interest, usage and reach of scientific publications. Another of these new filters is the Research Blogging platform, which was created in 2007 and now has over 1,230 active blogs, with over 26,960 entries posted about peer-reviewed research on subjects ranging from Anthropology to Zoology. This study takes a closer look at RB, in order to get insights into its contribution to the rapidly changing landscape of scientific communication.

Advances in primary immunodeficiency diseases in Latin America: epidemiology, research, and perspectives

Primary immunodeficiencies (PIDs) are genetic disorders of the immune system comprising many different phenotypes. Although previously considered rare, recent advances in their clinical, epidemiological, and molecular definitions are revealing how much we still need to learn about them. For example, geographical and ethnic variations as well as the impact of certain practices influence their frequency and presentation, making it necessary to consider their study in terms of regions. The Latin American Society for Immunodeficiencies was established as an organization dedicated to provide scientific support for basic and clinical research and to develop tools and educational resources to promote awareness in the medical community. Initiatives such as these are positively influencing the way PIDs are tackled in these countries, as shown by recent reports and publications. This paper provides a historical compilation and a current view of the many issues faced by scientists studying these diseases in these countries, highlighting the diverse scientific contributions and offering a promising perspective for the further developments in this field in Latin America.

Towards a hybrid approach for adapting web graphical user interfaces to heterogeneous devices using context

Ubiquitous Computing promises seamless access to a wide range of applications and Internet based services from anywhere, at anytime, and using any device. In this scenario, new challenges for the practice of software development arise: Applications and services must keep a coherent behavior, a proper appearance, and must adapt to a plenty of contextual usage requirements and hardware aspects. Especially, due to its interactive nature, the interface content of Web applications must adapt to a large diversity of devices and contexts. In order to overcome such obstacles, this work introduces an innovative methodology for content adaptation of Web 2.0 interfaces. The basis of our work is to combine static adaption - the implementation of static Web interfaces; and dynamic adaptation - the alteration, during execution time, of static interfaces so as for adapting to different contexts of use. In hybrid fashion, our methodology benefits from the advantages of both adaptation strategies - static and dynamic. In this line, we designed and implemented UbiCon, a framework over which we tested our concepts through a case study and through a development experiment. Our results show that the hybrid methodology over UbiCon leads to broader and more accessible interfaces, and to faster and less costly software development. We believe that the UbiCon hybrid methodology can foster more efficient and accurate interface engineering in the industry and in the academy.

Hydrochemical variability at the Upper Paraguay Basin and Pantanal wetland

Compartmentalization is a prerequisite to understand large wetlands that receive water from several sources. However, it faces the heterogeneity in space and time, resulting from physical, chemical and biological processes that are specific to wetlands. The Pantanal is a vast seasonally flooded continental wetland located in the centre of South America. The chemical composition of the waters that supply the Pantanal (70 rivers) has been studied in order to establish a compartmentalization of the wetland based on soil-water interactions. A PCA-based EMMA (End-Members Mixing Analysis) procedure shows that the chemistry of the rivers can be viewed as a mixture of 3 end-members, influenced by lithology and land use, and delimiting large regions. Although the chemical composition of the end-members changed between dry and wet seasons, their spatial distribution was maintained. The results were extended to the floodplain by simple tributary mixing calculation according to the hydrographical network and to the areas of influence for each river when in overflow conditions. The resulting map highlights areas of high geochemical contrast on either side of the river Cuiaba in the north, and of the rivers Aquidauana and Abobral in the south. The PCA-based treatment on a sampling conducted in the Nhecolandia, a large sub region of the Pantanal, allowed the identification and ordering of the processes that control the geochemical variability of the surface waters. Despite an enormous variability in electrical conductivity and pH, all data collected were in agreement with an evaporation process of the Taquari River water, which supplies the region. Evaporation and associated saline precipitations (Mg-calcite, Mg-silicates K-silicates) explained more than 77% of the total variability in the chemistry of the regional surface water sampling.
