Autism is a neurodevelopmental disorder where genetic factors play causal role. This case-control study explored the association between perinatal and socioeconomic status with risk of autism. It was a case control study among children who came from different areas of the country during the period of 2005 to 2015 for assessment in the outdoor facility of Bangabandhu Sheikh Mujib Medical University. One hundred children were diagnosed autism by Autism Diagnostic Observation Schedule (ADOS)-Generic. Among them 79 were boys and 21 were girls. Another one hundred children without autism were taken as control, 65 of them were boys and 35 were girls. Perinatal and socioeconomic risk factors were analyzed in these two groups, using medical records. Mean age of the ASD children was 3.51+1.58 year and control was 3.80+1.53. Male predominance was observed in ASD children. After univariate analysis three significant variables identified to pose as risk for autism. These were parental advanced level of education (P=<0.001), urban residence (P=<0.001) and neonatal jaundice (P=<0.001). Variables like male sex, occupation as service holder and low birth weight at birth approached significance at the 0.05 level. Results suggested that parental profile as well as perinatal environment are associated with risk of autism and this factors act independently.
Spatial justice in relation to the urban amenities distribution in Austin, Texas

In addition to enhancing our theoretical grasp of justice, thinking spatially about it can also reveal important new insights that broaden our practical understanding in order to advance justice and democracy. On the other hand, these opportunities won’t be as obvious if the spatial equities aren’t made apparent and strong. Austin city has experienced a fast-urban growing in the past decades. As urban areas grow, the public facilities should increase. The purpose of this paper investigates Facilities in terms of public facilities. Even though we said that the concept of justice is very complex, it is possible to get an understanding of it by using a quantitative method. This paper explores the condition of urban justice and opportunities for accessibility to public facilities for all residents in Austin by using GIS data and the Fuzzy logic model. The facilities and services maps were made in GIS and after the Euclidean Distance and Reclassify function in Arc Map, the Fuzzy Logic model was used to analyze spatial justice. The result shows the facilities are distributed properly. Spatial justice is in the context of Austin and residents enjoy spatial justice.

The new wave of wireless technologies, fitness trackers, and body sensor devices can have great impact on healthcare systems and the quality of life. However, there have not been enough studies to prove the accuracy and precision of these trackers. The objective of this study was to evaluate the accuracy, precision, and overall performance of seventeen wearable devices currently available compared with direct observation of step counts and heart rate monitoring. Methods: Each participant in this study used three accelerometers at a time, running the three corresponding applications of each tracker on an Android or iOS device simultaneously. Each participant was instructed to walk 200, 500, and 1,000 steps. Each set was repeated 40 times. Data was recorded after each trial, and the mean step count, standard deviation, accuracy, and precision were estimated for each tracker. Heart rate was measured by all trackers (if applicable), which support heart rate monitoring, and compared to a positive control, the Onyx Vantage 9590 professional clinical pulse oximeter. Results: The accuracy of the tested products ranged between 79.8% and 99.1%, while the coefficient of variation (precision) ranged between 4% and 17.5%. MisFit Shine showed the highest accuracy and precision (along with Qualcomm Toq), while Samsung Gear 2 showed the lowest accuracy, and Jawbone UP showed the lowest precision. However, Xiaomi Mi band showed the best package compared to its price. Conclusions: The accuracy and precision of the selected fitness trackers are reasonable and can indicate the average level of activity and thus average energy expenditure.
SCREENCAST VIDEOGRAPHY: ONLINE CONSUMER BEHAVIOUR METHODOLOGY
Fatema Kawaf 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06
If a picture speaks a thousand words, imagine what kind of story a video could tell… The need for videography in Consumer Research has been recognised and endorsed by the ACR Film Festival, which has been growing for more than a decade. Belk and Kozinets (2012) argue “As industry increasingly embraces videographic techniques for representing consumer realities and portraying their marketing research findings, it is useful for our field to follow suit and, in many ways, lead the charge towards finding new, rich forms for understanding the consumer”. Indeed the ACR film festival has showcased incredible research that highlights the importance of videography, the rich data it provides and the captivating presentation and storytelling of consumer research (e.g. Hietanen, Schouten, & Vaniala, 2013; Kawaf, 2014; Rokka, Rousi, & H?m?l?inen, 2014; Seregina, Campbell, Figueiredo, & Uotila, 2013; Veer, 2014) This research takes videography to a new level in consumer research, an unavoidable move toward studying the ever-growing arena of digital consumption. Therefore, this abstract presents screencast videography as a method of studying consumer behaviour in the specific context of online fashion shopping. With the rapid evolving nature of technology, various experiences have moved completely or partially to the digital world. New experiences and opportunities arise everyday for the average individual as well as for businesses of all sizes. This is apparent in the rapid growth of ‘netnography’ as a method for studying ‘the field behind the screen’ by Kozinets (2002). This method has allowed an infinite number of possibilities for studying online communities in digital ethnographic fashion. Similarly, if visual ethnographies and videography research such as Burning Man, ESPN and Nike Town (Kozinets, 2002a; Kozinets et al., 2004; Penaloza, 1998) allowed such rich understanding of observable experiences, so far the same has not been possible in the context of online experiences. The consumption experience of online fashion websites along with browsing, shopping or interacting with web atmospherics occur within the personal and private space of the individual; and so there is currently no method in the literature that allows for such work to be done in studying online experiences and behavioural decision making processes. Therefore, my proposition in this abstract is to introduce screencast videography as a form of videographic interpretive approach to studying the consumption experience of digital spaces. Screencasting is defined, in Information Technology research, as “a method of presenting digitally recorded playback of computer screen output which often contains audio narration” (Brown, Luterbach, & Sugar, 2009, p.1748). The use of screencasts is most popular in education and particularly in virtual learning environments. Brown et al. (2009, p.1748) argue, “Because screencasting captures desktop activity along with audio commentary, it can be a particularly effective method of explaining computer-based procedures”. I work on employing this method in understanding the consumption experience in online context; the empirical use of this method has been presented at the ACR film festival (Kawaf, 2014). Similar videography, this approach allows for the production of natural data (Knoblauch, Schnettler, Raab, & Soeffner, 2006) and is indeed less obtrusive since the hindering camera effect argued by Belk and Kozinets (2005) is not present in this approach.
An Initial Study for Finite Element Analysis of Residual Stress for Butt Welding Joint
Chowdhury Fatema,Kim Myung Hyun 대한조선학회 2011 대한조선학회 학술대회자료집 Vol.2011 No.11
Welding plays an important role as an efficient joining process in engineering construction field. During welding residual stresses are caused by localized heating followed by rapid cooling in the weld bead and heat affected zone of the base metal. It is of great consideration to estimate the residual stress which is induced in the welded region to predict the behaviors of welded structures for achieving the reliable design and safest design. This paper describes the numerical method, using commercial simulation software Msc Marc 2007, to predict residual stresses in butt welded structure containing multi pass welds for mild steel. Coupled thermo-mechanical analysis has been carried out to evaluate the magnitude and distribution of residual stresses induced at two similar plates of full penetration weld. Multi-pass weld has been simulated, with thermal loading applied to the model on a pass by pass basis for plane strain solid element. The results of this finite element analysis are compared with the obtained value of experimental residual stress data to confirm the accuracy of the method.
