As TIC, as práticas de ensino supervisionadas, a investigação e a inovação : os blogues educativos & a segurança na internet

Presentemente, em Portugal, estima-se que a utilização das TIC (Tecnologias da Informação e da Comunicação), pelos designados nativos digitais, corresponde a cerca de 98,S°/o. Considerando que os nativos digitais correspondem aos cidadãos que nasceram somente há 15 anos atrás, significa que toda a atual população escolar vive e convive rodeada de dispositivos e de ferramentas digitais no âmbito das suas rotinas diárias. Contudo, em termos gerais, não se tem verificado a mesma realidade no espaço educativo onde a presença de computadores e de uma ligação à Internet continua a ser muito escassa e incipiente. As Práticas de Ensino Supervisionadas, no âmbito do Mestrado em Educação Pré-escolar e Ensino do 1° Ciclo do Ensino Básico, têm vindo a constituir uma «janela de oportunidades» para a realização de investigações sobre a implementação das TIC no processo de ensino aprendizagem. Apesar de todos os constrangimentos, tem sido possível promover-se uma investigação que se pode considerar inovadora e exploratória pela inexistência de investigações anteriores similares. Para o efeito, é objetivo apresentarem-se os resultados de uma investigação que envolveu a utilização de blogues, no sentido destas ferramentas digitais promoverem novos contextos de aprendizagem e, ainda, com o objetivo de serem uma «ponte» que permitiu a aproximação entre a escola e a família. Um outro exemplo de investigação a apresentar diz respeito à utilização segura da Internet. Dos resultados obtidos foi possível verificar que crianças de 7/8 anos já fazem uma utilização autónoma da internet mas, em vários casos, foi possível averiguar-se que os respetivos pais não têm noção relativamente às utilizações que os seus educandos fazem no chamado ciberespaço. Em termos globais, foi possível apurar-se que as crianças aderem muito facilmente à utilização das tecnologias digitais na sala de aula, os alunos mostraram-se sempre muito envolvidos e motivados. Para terminar, é importante referir que, apesar de todas as vantagens apuradas, quer os alunos quer os pais, continuam a afirmar que a presença dos professores é fundamental e imprescindível no processo de ensino e de aprendizagem.

"Am I Korean American?": beliefs and practices of parents and children living in two languages and two cultures

The purpose of this study is to explore attitudes and practices regarding their heritage language and the dominant English language among Korean American immigrant families. Using the framework of Language Ideology (Silverstein, 1979), I had three research questions: a) why do parents send their children to a Korean language school, b) what attitudes do immigrant parents and their children show toward Korean and English, and c) how are the parents and children involved in the practices of these two languages? I conducted a survey of parents whose children attended a Korean language school in Urbana-Champaign, Illinois, where the number of Korean sojourners (temporary residents) exceeds that of Korean immigrants. Forty participant parents provided demographic information. They described their children's language-use patterns depending on interlocutors as well as their language proficiency in both Korean and English. The reasons for sending their children to the Korean language school were significantly different depending on the respondents' residential status. In comparison to the sojourners, immigrants tended to give more priority to their children's oral language development and Korean identity construction. I also conducted case studies of three Korean immigrant families with 3- to 5-year-old children, using interviews, observations, and photographs of children's work. The collected data were analyzed according to themes such as daily life, parental beliefs about two languages, practices in two languages, children's attitudes toward two languages, and challenges and needs. Despite individual families' different immigration histories, the three families faced some common challenges. Because of their busy daily routines and different lifestyles, the immigrant families had limited interactions with other Koreans. The parents wanted their children to benefit from two communities and build a combined ethnic identity as Korean Americans. I argue that a Korean language school should expand its role as a comfort zone for all Koreans and Korean Americans. This study explores the heterogeneity among Korean sojourner and immigrant families and their language use and identity construction.

Satisfação dos utentes com o tratamento da dor

A dor constitui atualmente um enorme obstáculo no quotidiano de mihares de pessoas em todo o mundo. Por essa razão, é considerada um problema de saúde pública, não só pelas repercussões individuais que provoca, mas também pelas consequências graves aos níveis social e económico. Desta forma, este estudo pretende examinar a satisfação dos utentes com o tratamento da dor, determinando os fatores sociodemográficos, clínicos e psicossociais (personalidade e espiritualidade) que influenciam essa mesma satisfação. Trata-se de um estudo transversal, descritivo-correlacional e quantitativo. A amostra utilizada é constituída por 78 participantes, com idades compreendidas entre os 30 anos e os 82 anos, correspondendo a uma média de idades de 64,88 anos. A maioria é casada/vive em união de fato e possui graus de escolaridade baixos (1º ciclo). Para se proceder á recolha de dados foi aplicado um questionário, cuja finalidade era a caraterização clinica e sociodemográfica dos participantes. Foram também usadas as seguintes escalas: Escala de satisfação para o tratamento da dor (PTSS), Escala de espiritualidade e o Inventário da personalidade (NEO-FFI-20). Os resultados demonstram que a maioria da amostra apresenta dor crónica, de origem músculo-esquelética e o tratamento farmacológico constitui o tratamento de eleição. A maioria (91%) dos participantes refere estar satisfeita ou muito satisfeita com o atual tratamento para a sua dor. Contudo, a análise dos dados revelou a existência de diferenças estatisticamente significativas entre a variável satisfação em diferentes dimensões com as seguintes variáveis sociodemográficas: género (p= 0.003, idade (p=0.010) e estado civil (p=0.045); clínicas: período temporal da dor (p= 0.013 e p=0.014), tipo de tratamento (p=0.011), programa de reabilitação (p= 0.003 e p= 0.005), seguimento em consulta da dor (p≤ 0.05 em cinco sub-dimensões da escala de satisfação), psicossociais: a personalidade em todas as dimensões com exceção da dimensão neuroticismo, e por fim a espiritualidade global (p= 0.008) e também na sua dimensão crenças (p=0.010). Palavras- chave: dor, satisfação com o tratamento, personalidade, espiritualidade.

Lecturas de la prensa popular: Un estudio de recepción del periódico Q'hubo en la localidad de Kennedy en Bogotá

En este trabajo de grado se aborda la relación entre las audiencias y los medios a partir de un estudio de recepción del diario Q’hubo en los sectores populares de Bogotá, específicamente en la localidad de Kennedy de esta ciudad. El estudio reconoce que las formas determinadas de interactuar con los medios están atadas a los contextos, las instituciones y los entornos culturales y sociales desde los que lector construye su realidad y se inserta en la sociedad actual. Por lo mismo, se nutre de estos elementos para entender los procesos de recepción a través de las formas cotidianas de consumo del diario Q’hubo frente al contexto mediático actual. Se sustenta que el Q’hubo se comunica con sus lectores combinando aspectos clásicos de la prensa popular y adaptando aspectos de diseño y lenguaje aportados por los nuevos medios. Lo que a su vez se relaciona con apropiaciones, usos y modos de leer de la audiencia, que reivindica interacciones tradicionales y desarrolla interacciones emergentes gracias a la convergencia de las tecnologías con la cultura letrada, oral y visual.

Effect Of Daily Use Of An Enzymatic Denture Cleanser On Candida Albicans Biofilms Formed On Polyamide And Poly(methyl Methacrylate) Resins: An In Vitro Study.

Candida biofilms on denture surfaces are substantially reduced after a single immersion in denture cleanser. However, whether this effect is maintained when dentures are immersed in cleanser daily is unclear. The purpose of this study was to evaluate the effect of the daily use of enzymatic cleanser on Candida albicans biofilms on denture base materials. The surfaces of polyamide and poly(methyl methacrylate) resin specimens (n=54) were standardized and divided into 12 groups (n=9 per group), according to study factors (material type, treatment type, and periods of treatment). Candida albicans biofilms were allowed to form over 72 hours, after which the specimens were treated with enzymatic cleanser once daily for 1, 4, or 7 days. Thereafter, residual biofilm was ultrasonically removed and analyzed for viable cells (colony forming units/mm(2)) and enzymatic activity (phospholipase, aspartyl-protease, and hemolysin). Factors that interfered with the response variables were analyzed by 3-way ANOVA with the Holm-Sidak multiple comparison method (α=.05). Polyamide resin presented more viable cells of Candida albicans (P<.001) for both the evaluated treatment types and periods. Although enzymatic cleansing significantly (P<.001) reduced viable cells, daily use did not maintain this reduction (P<.001). Phospholipase activity significantly increased with time (P<.001) for both materials and treatments. However, poly(methyl methacrylate) based resin (P<.001) and enzymatic cleansing treatment (P<.001) contributed to lower phospholipase activity. Aspartyl-protease and hemolysin activities were not influenced by study factors (P>.05). Although daily use of an enzymatic cleanser reduced the number of viable cells and phospholipase activity, this treatment was not effective against residual biofilm over time.

Bone quality associated with daily intake of coffee: a biochemical, radiographic and histometric study

Caffeine induces loss of calcium and influences the normal development of bone. This study investigated the effects of coffee on bone metabolism in rats by biochemical measurement of calcium, bone densitometry and histometry. Male rats, born of female treated daily with coffee and with coffee intake since born, were anesthetized, subjected to extraction of the upper right incisor, and sacrificed 7, 21 and 42 days after surgery. Blood and urine samples were taken, and their maxilla radiographed and processed to obtain 5-µm-thick semi-serial sections stained with hematoxylin and eosin. The volume and bone quality were estimated using an image-analysis software. The results showed significantly greater amount of calcium in the plasma (9.40 ± 1.73 versus 9.80 ± 2.05 mg%) and urine (1.00 ± 0.50 versus 1.25 ± 0.70 mg/24 h) and significantly less amount in bone (90.0 ± 1.94 versus 86.0 ± 2.12 mg/mg bone), reduced bone mineral density (1.05 ± 0.11 versus 0.65 ± 0.15 mmAL), and lower amount of bone (76.19 ± 1.6 versus 53.41 ± 2.1 %) (ANOVA; p≤0.01) in animals treated with coffee sacrificed after 42 days. It may be concluded that coffee/caffeine intake caused serious adverse effects on calcium metabolism in rats, including increased levels of calcium in the urine and plasma, decreased bone mineral density and lower volume of bone, thus delaying the bone repair process.

Reviewed evidence about the safety of the daily use of alcohol-based mouthrinses

Current scientific knowledge provides clear evidence that alcohol-based mouthwashes can be beneficial in a daily oral health routine, including dental hygiene and plaque control. Several issues are worth discussing, in spite of the wealth of supporting evidence. Despite some undesirable effects to some people, like burning sensation, and some contraindications, like the use by infants, alcohol addicts and patients with mucosal injuries, there is no reason to avoid the use of alcohol-containing mouthwashes as long as they are used following proper guidance by dental professionals and the manufacturers' instructions. The alleged correlation between oral cancer and alcohol-based mouthrinses presents so little, weak, inconsistent and even contradictory evidence in the literature that any kind of risk warning to patients would be uncalled for. Antimicrobial mouthrinses are safe and effective in reducing plaque and gingivitis, and should be part of a comprehensive oral health care regimen that includes brushing, flossing and rinsing to prevent or minimize periodontal disease.

Perception of difficulties with vision-related activities of daily living among patients undergoing unilateral posterior capsulotomy

OBJECTIVES: To assess the influence of Nd:YAG (neodymium: yttrium-aluminum- garnet) laser unilateral posterior capsulotomy on visual acuity and patients' perception of difficulties with vision-related activities of daily life. METHODS: We conducted an interventional survey that included 48 patients between 40 and 80 years of age with uni- or bilateral pseudophakia, posterior capsule opacification, and visual acuity <0.30 (logMAR) in one eye who were seen at a Brazilian university hospital. All patients underwent posterior capsulotomy using an Nd:YAG laser. Before and after the intervention, patients were asked to complete a questionnaire that was developed in an exploratory study. RESULTS: Before posterior capsulotomy, the median visual acuity (logMAR) of the included patients was 0.52 (range 0.30-1.60). After posterior capsulotomy, the median visual acuity of the included patients improved to 0.10 (range 0.0-0.52). According to the subjects' perceptions, their ability to perform most of their daily life activities improved after the intervention (p<0.05). CONCLUSIONS: After patients underwent posterior capsulotomy with an Nd:YAG laser, a significant improvement in the visual acuity of the treated eye was observed. Additionally, subjects felt that they experienced less difficulty performing most of their vision-dependent activities of daily living.

NONLINEAR PERIODIZATION MAXIMIZES STRENGTH GAINS IN SPLIT RESISTANCE TRAINING ROUTINES

Monteiro, AG, Aoki, MS, Evangelista, AL, Alveno, DA, Monteiro, GA, Picarro, IDC, and Ugrinowitsch, C. Nonlinear periodization maximizes strength gains in split resistance training routines. J Strength Cond Res 23(4): 1321-1326, 2009-The purpose of our study was to compare strength gains after 12 weeks of nonperiodized (NP), linear periodized (LP), and nonlinear periodized (NLP) resistance training models using split training routines. Twenty-seven strength-trained men were recruited and randomly assigned to one of 3 balanced groups: NP, LP, and NLP. Strength gains in the leg press and in the bench press exercises were assessed. There were no differences between the training groups in the exercise pre-tests (p > 0.05) (i.e., bench press and leg press). The NLP group was the only group to significantly increase maximum strength in the bench press throughout the 12-week training period. In this group, upper-body strength increased significantly from pre-training to 4 weeks (p < 0.0001), from 4 to 8 weeks (p = 0.004), and from 8 weeks to the post-training (p < 0.02). The NLP group also exhibited an increase in leg press 1 repetition maximum at each time point (pre-training to 4 weeks, 4-8 week, and 8 weeks to post-training, p < 0.0001). The LP group demonstrated strength increases only after the eight training week (p = 0.02). There were no further strength increases from the 8-week to the post-training test. The NP group showed no strength increments after the 12-week training period. No differences were observed in the anthropometric profiles among the training models. In summary, our data suggest that NLP was more effective in increasing both upper- and lower-body strength for trained subjects using split routines.

Transient effects of stretching exercises on gait parameters of elderly women

This study aimed to analyse the effects of a single stretching exercise session on a number of gait parameters ill elderly participants in all attempt to determine whether these exercises can influence the risk of fall. Fifteen healthy women living in the community Volunteered to participate in the study. A kinematic gait analysis was performed immediately before and after a session of static stretching exercises applied oil hip flexor/extensor muscles. Results showed a significant influence of stretching exercises on a number of gait parameters, which have previously been proposed as fall predictors. Participants showed increased gait velocity, greater step length and reduced double Support time during stance after performing stretching exercises, suggesting improved stability and mobility. Changes around the pelvis (increased anterior-posterior tilt and rotation range of motion) resulting from the stretching exercises were suggested to influence the gait parameters (velocity, step length and double support time). Therefore, stretching exercises were shown to be a promising strategy to facilitate changes in gait parameters related to the risk of fall. Some other gait variables related to the risk of fall remained Unaltered (e.g., toe clearance). The stable pattern of segmental angular velocities was proposed to explain the stability of these unchanged gait variables. The results indicate that stretching exercises, performed oil a regular (daily) basis, result in gait adaptations which can be considered as indicative of reduced fall risk. Other Studies to determine whether regular stretching routines are an effective strategy to reduce the risk of fall are required. (C) 2008 Elsevier Ltd. All rights reserved.

Children’s respiratory health and daily particulate levels in ten non-urban communities

We conducted a study to assess the association between the acute respiratory health of children and the levels of particulates in communities near and away from active opencast coal mines. The study enrolled children aged 1–11 years from the general population of five socioeconomically matched pairs of nonurban communities in northern England. Diaries of respiratory events were collected for 1405 children, and information was collected on the consultations of 2442 children with family/general practitioners over the 6-week study periods during 1996–1997, with concurrent monitoring of particulate levels. The associations found between daily PM10 levels and respiratory symptoms were frequently small and positive and sometimes varied between communities. The magnitude of these associations were in line with those from previous studies, even though daily particulate levels were low, and the children were drawn from the general population, rather than from the population with respiratory problems. The associations among asthma reliever use, consultations with general practitioners, and daily particulate levels were of a similar strength but estimated less precisely. The strength of association between all respiratory health measures and particulate levels was similar in communities near and away from opencast coal mining sites.
