Wireless Health Monitoring using Passive WiFi Sensing

This paper presents a two-dimensional phase extraction system using passive WiFi sensing to monitor three basic elderly care activities including breathing rate, essential tremor and falls. Specifically, a WiFi signal is acquired through two channels where the first channel is the reference one, whereas the other signal is acquired by a passive receiver after reflection from the human target. Using signal processing of cross-ambiguity function, various features in the signal are extracted. The entire implementations are performed using software defined radios having directional antennas. We report the accuracy of our system in different conditions and environments and show that breathing rate can be measured with an accuracy of 87% when there are no obstacles. We also show a 98% accuracy in detecting falls and 93% accuracy in classifying tremor. The results indicate that passive WiFi systems show great promise in replacing typical invasive health devices as standard tools for health care.Comment: 6 pages, 8 figures, conference pape

Population ageing in Bangladesh and its implication on health care

In Bangladesh as in other regions of the world, the population ages 60 years and older is growing faster than the total population. Growth in the elderly population relative to other age groups challenges existing health services, family relationships and social security. With continued population ageing, the loss of cognitive function will potentially cause enormous social and economic burden on families, communities and, to the country. Using the census and secondary data, the paper investigates that increasing longevity and declining fertility are combining to convert the population age structure from young to old. This combination is resulting implications on the family health care and unmet need of health care services in the public sector. The support index shows that there will be fewer persons to support elderly population in future with implications in traditional family care. The care index shows the cost of burden for long term care associated with the shift in the population age structure. As a consequence Bangladeshi societies will confront population aging without traditional kin support

Bubble Rise Phenomena Through Newtonian & Non-Newtonian Fluids

The characteristics of bubble rise phenomenon in three liquids were investigated and are reported here. The experimental rig consists of two transparent cylindrical columns – one a polycarbonate tube of 125 mm diameter and the other an acrylic tube of 400 mm diameter. The rig also consists of a lifting device designed to hold a video camera for taking bubble images. Water and two non-Newtonian fluids (0.025% and 0.045% by weight of polyacrylamide solutions) were used in this study. The smaller polycarbonate tube was used to study the velocity and the drag coefficient under vacuum. The bigger acrylic tube was used to study the influence of the size of bubbles

Utilization of antenatal care among pregnant women of urban slums of Dhaka City, Bangladesh

Maternal health services have a potentially critical role in the improvement of reproductive health. The use of health services is related to the availability, quality and cost of the services, as well as to social structure, health beliefs and the personal characteristics of the users. Antenatal care (ANC) is an important determinant of high maternal mortality rate and one of the basic components of maternal care on which the life of mothers and babies depend. It is a key strategy for reducing maternal mortality, but millions of women in developing countries do not receive it. Extracting 3549 women from the 2006-2007 Urban Health Survey, this study assessed the utilization of antenatal care and its related factor in urban slums for pregnant women. A Cross-sectional survey was carried out large, medium and small urban squatter settlements of Dhaka City. Two hundred married women in the age range 15-49 years were interviewed. Socio-demographic characteristics of women who received and who did not receive antenatal care in their previous pregnancy were assessed by frequency distribution and bivariate analysis. Antenatal care used in any of the previous pregnancy among women under study was 861(64.3%). Education and ANC is significantly related suggesting that the higher the level of education the higher is the likelihood of receiving ANC during pregnancy because educated women are aware about the importance of ANC during pregnancy. There is a strong association between the income of the respondents and ANC received by the respondents. This study indicates that overall knowledge about antenatal care was found to be better among women who had utilized antenatal care as compared to women who did not receive antenatal care.. There is also a need to evaluate the services provided by government health facilities and to find out why women are not utilizing the government health services though these services are available at subsidized rate

Comparison between Male and Female Elite Wrestlers: A Psychological Study

Anxiety is recognized one of the main factor that reduces athlete's performance in games and sports but its depend on the nature of anxiety, So many psychological studies and lot of researchers and their research evidences support that high levels of anxiety can have a deteriorating effect on an individual athlete or team performance. This research paper was carried out to examine possible significant differences in cognitive anxiety, somatic anxiety, and self confidence among elite male and female wrestlers. The present investigation was used to form the samples as twenty five (N=25) medalist (12 male and 13 female) randomly selected from different weight categories in All India interuniversity wrestling competition. All subject readily agreed to volunteer as subject for collection of data. For this purpose measuring instruments was used Competitive State Anxiety Inventory - 2 (CSAI-2) Test developed by Martine's et. al (1990) , after that collected data was analyzed by using t- test to find out the significance differences between male and female elite wrestlers on above mentioned sub- psychological variable and the level of significance was set at 0.05 level of confidence .The obtain result advocate that each sub-variable (cognitive anxiety, somatic anxiety, and self confidence)  findings in contrast and that found insignificance difference among elite male and female elite wrestlers
