National epilepsy movement in Brazil

Purpose: To establish a social network of epilepsy lay organization in Brazil to provide advocacy for people with epilepsy and eventually forma powerful National Epilepsy movement. Method.-We actively searched for any associations, support groups or organizations related to epilepsy in the country by personal contacts, internet search and by telephone search. Contact was then established with any entity found. Results: The first meeting was held in Campinas in March 2003, and was attended by 270 people, including many people with epilepsy, members of all eleven epilepsy associations found, health professionals and representatives of the Brazilian chapters of IBE and ILAE and the Brazilian Ministry of Health. This first meeting resulted in a National Movement expressed every year through the National Week of Epilepsy and National Meeting of Lay Associations. Discussion: This strategy, developed by ASPE, was simple and effective, and in a very short time a national movement was active. These actions could be reproduced in any country developing a campaign against epilepsy. it is important to consider that this is a process of empowerment, thus people with epilepsy need to take actions into their own hands and to be active participants

Stigma and attitudes on epilepsy - A study with secondary school students

Purpose: To evaluate whether an inappropriate attitude towards a person having an epileptic seizure contributes to the stigma found in society and whether an appropriate attitude helps to diminish it in the short term; to perform a long term investigation about information remembered and stigma perception after an educational lecture. Method. This study was performed in two steps: Step 1. students of first year of high school of two schools in Campinas completed a questionnaire including the Stigma Scale of Epilepsy following a seizure demonstration. They were divided into three groups: a) one group had a demonstration of proper attitudes towards someone having an epileptic seizure; b) one group was shown incorrect procedures; c) control group. After the completion of the questionnaire, an educational lecture about epilepsy was given. Step 2: six months later, the questionnaire was re-administered. Results: The comparison between the four groups (step 1 and step 2) show a significant difference (Anova (3,339)=2.77; p=0.042). Pairwise comparison using Fisher's Least-Significant-Difference Test showed a significant difference between the group shown incorrect procedures (step 1) versus step 2, and the control group (step 1) versus step 2, but no difference between the group shown correct procedures (step 1) versus step 2. Discussion: Exhibiting proper attitudes towards a person experiencing an epileptic seizure may cause significant differences among the subjects' degrees of stigma towards people with epilepsy. It is therefore fundamental that there should be de-stigmatization campaigns provided, to correct information and provide appropriate education

Stigma scale of epilepsy - Validation process

Purpose: To validate a Stigma Scale of Epilepsy (SSE). Methods: The SSE was completed by 40 adult with epilepsy attending an Outpatient Epilepsy Clinic at the University Hospital of UNICAMP, and by 40 people from the community. People were interviewed on an individual basis; a psychologist read the questions to the subjects who wrote the answers in a sheet. The procedure was the same for all the subjects and completion took around ten minutes. Results: The SSE has 24 items. The internal consistency of the SSE showed alpha. Cronbach's coefficient 0.88 for the patients with epilepsy and 0.81 for the community. The overall mean scores of the Stigma Scale of Epilepsy formula were: 46 (SD=18.22) for patients and 49 (SD=13.25) for the community where a score of 0 would suggest no stigma, and 100 maximum stigma. Discussion: The SSE has satisfactory content validity and high internal consistency. It allows the quantification of the perception of stigma by patients and people from community; this can then be used for interventional studies, such as mass media campaign in minimizing the negative facets of stigma

Wide-bandgap high- k Y2 O3 as passivating interlayer for enhancing the electrical properties and high-field reliability of n-Ge metal-oxide-semiconductor capacitors with high- k HfTiO gate dielectric

High- k and wide-bandgap Y2 O3 was proposed as an interlayer in n-Ge metal-oxide-semiconductor (MOS) capacitor with HfTiO gate dielectric for passivating its dielectric/Ge interface, and thus improving its electrical properties and high-field reliability. Results showed that as compared to the Ge MOS capacitor with HfTiO dielectric, the sample with HfTiO/ Y2 O3 dielectric had better electrical properties such as higher dielectric constant (k=24.4), lower interface-state density, and less frequency-dependent C-V dispersion, and also better reliability with less increases in gate leakage and interface states after high-field stressing. This should be attributed to the excellent interfacial quality of Y2 O3 /Ge with no appreciable growth of unstable GeOx at the interface as confirmed by transmission electron microscopy. Moreover, Y 2 O3 can also act as a barrier against the diffusions of Ge, Hf, and Ti, thus further improving the interface quality. © 2009 American Institute of Physics.published_or_final_versio

Training medical students to improve the management of people with epilepsy

Purpose: To evaluate the knowledge, attitude and perception of medical students prior to and after a training course about epilepsy. Methods: We used a KAP questionnaire with sixty-one questions which assesses knowledge, attitude and practice of epilepsy. Questionnaires were completed by 185 medical students, before and after epilepsy training. We compared the answers to see whether the lecture had changed the knowledge, attitude and practice in epilepsy. Results: One hundred and six students completed the questionnaire before an eight hour course on epilepsy and 79 students completed the questionnaire one year after the course. Comparison of the knowledge scores prior to (mean=53.9, standard deviation=11.4) and after the course (mean=63.8, standard deviation=11.9) showed that students had improved knowledge after the course (t-test=5.6, p < 0.001). Discussion: Training course on epilepsy for medical students can promote improvement in the knowledge, attitudes and perception regarding epilepsy, which is maintained one year later. These results highlight the importance of continuous educational programs within the Medical Curriculum

A reliability study on green InGaN-GaN light-emitting diodes

In this letter, the reliability of green InGaN-GaN light-emitting diodes (LEDs) has been analyzed by correlating the defect density of wafers with various device parameters, including leakage current, 1/f noise, and degradation rate. It was found that as the wavelength of green LEDs increases from 520 to 550 nm by increasing the indium content in the quantum wells, the defect density also increases, thus leading to larger leakage current, enhanced noise magnitude, and shortened device lifetime. © 2009 IEEE.published_or_final_versio

Regions of significant influence on unforced global mean surface air temperature variability in climate models

We document the geographic regions where local variability is most associated with unforced global mean surface air temperature (GMT) variability in Coupled Model Intercomparison Project Phase 5 coupled global climate models (GCMs) at both the subdecadal and interdecadal timescales. For this purpose, Regions of Significant Influence on GMT are defined as locations that have a statistically significant correlation between local surface air temperature (SAT) and GMT (with a regression slope greater than 1), and where local SAT variation leads GMT variation in time. In both GCMs and observations, subdecadal timescale GMT variability is most associated with SAT variation over the eastern equatorial Pacific. At the interdecadal timescale, GMT variability is also linked with SAT variation over the Pacific in many GCMs, but the particular spatial patterns are GCM dependent, and several GCMs indicate a primary association between GMT and SAT over the Southern Ocean. We find that it is difficult to validate GCM behavior at the interdecadal timescale because the pattern derived from observations is highly depended on the method used to remove the forced variability from the record. The magnitude of observed GMT variability is near the ensemble median at the subdecadal timescale but well above the median at the interdecadal timescale. GCMs with a stronger subdecadal relationship between GMT and SAT over the Pacific tend to have more variable subdecadal GMT while GCMs with a stronger interdecadal relationship between GMT and SAT over parts of the Southern Ocean tend to have more variable GMT

Spreading-resistance temperature sensor on silicon-on-insulator

A spreading-resistance temperature (SRT) sensor is fabricated on silicon-on-insulator (SOI) substrate and achieves promising characteristics as compared with similar SRT sensor on bulk silicon wafer. Moreover, experimental results show that the maximum operating temperature of thin-film (1.2 μm) SOI SRT sensor can reach 450 °C, much higher than 350 °C of thick-film (10 μm) SOI SRT sensor under the same current level. With complete oxide isolation, this sensor structure can be potentially used in low-power integrated sensors operating at temperatures as high as 450 °C.published_or_final_versio
