Design: The BDHS pooled data is used for determining the key outcome variables HAZ, stunting, and severe stunting. Trends, kernel-weighted local polynomial smoothing illustrations, pooled multivariable Linear Probability Model (LPM), Ordinary Least Squares method (OLS), and regression decomposition were used. Participants: Mothers having 0-35 months children, the most critical age range for growth faltering. Results: The mean HAZ increased by 0.91(±1.53) with 0.041 annual average change, while the percentages of stunting (-26.63 ±0.54) and severe stunting (-21.12 ±0.48) showed a reduction with 1.21 and 0.96 average annual changes,...

The pathophysiology of OME is negative pressure due to eustachian tube dysfunction. In children adenoid enlargement is associated with enlargement of the tonsils. Surgical treatment is advocated when conservative treatment fails. Surgical treatment consists of adenotonsillectomy with myringotomy. Negative middle ear pressure is expected to improve after surgical intervention. Objectives: To see the pressure changes after surgical treatment of OME. Methods: Among 68 subjects with OME, 88 ears were operated. Adenotonsillectomy was done in all subjects. In addition myringotomy was done in 65 ears and myringotomy with grommet insertion was done in 23 ears. In post-operative period all patient were followed up at end of 1 month, 3 month and 6 month with tympanometry. Results: Pre operatively type B tympanogram was 67(76.13%) whereas type Atympanogram was 0(0%). At end of 6 month type A curve was 49(61.27%) and type B tympanogram was 9(11.25%) that indicates improvement of middle ear function after operation. Conclusion: Tympanometric improvement was significant after 6 month of surgery.

Infectious diseases are leading causes of child mortality, and lack of exclusive breastfeeding (EBF) among infants aged 0–6 months increases child morbidity and mortality from various infectious diseases in developing countries. However, as per existing literature, no study has been conducted yet to determine the lack of EBF practice effect on child mortality in Bangladesh. With this backdrop, the authors intend to measure the likelihood of infectious diseases due to the lack of EBF of infants aged 0–6 months in Bangladesh. Materials and methods This study used Bangladesh Demographic and Health Survey (BDHS) data over 1996–97 to 2017–18. The mothers of infants aged 0–6 months who were willingly participated in the BDHSs were considered to include in our analysis. Initially, there we...

Those three elements are divide and rule, colonial education, and British laws. The British took some reformative initiatives that ostensibly deserve appreciation such as the development of a predictable legal system, investment in infrastructure development, and education in the late nineteenth and mid-twentieth centuries. However, most colonial policies and reforms were against the will and welfare of the people of India. The British took away India’s resources and introduced the English educational system to create an educated and elite buffer class for its own interests. It also introduced positivistic and predictable laws and repressive and discriminatory measures, including force, to control the natives and prevent anti-British agitation, protests, and armed uprisings in India. Although the consequences of British col...

A sample of 240 homeless children was collected from 12 different locations in the study area during the period from November 2014 to July 2015 by using a structured questionnaire and the simple random sampling method. The anthropometric measurements and background data were collected from these children. Analyses reveal that male children are significantly high in homelessness situation (85%). Nearly two-third of the homeless children were malnourished including about 60.42% were underweight and 6.25% were overweight conditions. Findings also demonstrate that about 63.75% children were able to manage their foods three times in a day and the rest 36.25% were able to manage twice or once meal in a day. Most of the study children (80%) regularly washed their hand before taking a meal and 57.5% taken bath in a daily basis, and about 61.5% of them have been suffered by di...

A 2-stage stratified random sampling design was used to collect the Bangladesh Demographic and Health Survey data during November 1999 to March 2000, in which 5333 living children aged 0 to 59 months and their mothers were weighed and measured to obtain their anthropometric data. The prevalence of wasting was assessed by the z scores approach, using the anthropometric criterion of weight-for-height and following the WHO guidelines and cutoff points. Results reveal that the prevalence of severe and moderate wasting were more common among children, and the overall prevalence of acute malnutrition was about 10%, indicating that it is one of the major public health problems in the country. Multivariate analysis showed that mother's BMI and media exposure, child's age and birth size, and respiratory sickness in childhood were significantly associated...

This project aims to give more autonomy to the elderly people in Colombia offering a comfortable and safe transportation that gives confidence not only to them but also their families. By this system the elderly can be transported and do what they need to do more independently. The main competitive advantage is the combination of transportation and the specialized assistance. The idea was born from the observation of population trends in this country and the world, including: the reduction in the number of children per family; the increase in the life span and the projected population growth of old people. The project was based on the observation of an unmet need in modern society and from this sprang a research process that included a series of primary and secondary investigations, the creating of a business model, a technical operational study, an investigation into the legal aspects and the study of the financial projections. Finally conclusions were drawn and recommendations made. During the development of the business plan, specifically in the valuation of the company, positive results were found, in both the moderate and optimistic scenarios, since it was shown that the payback period of the investment is in the fourth and in the third year respectively. These results showed that financially the project is a unique business opportunity and it is also a project of great interest and social impact.

Data from the Demographic and Health Survey Bangladesh were used to evaluate the influences of several significant socioeconomic, demographic, health system and community factors on the current status of malnutrition among 5333 under-5 years children. Results reveal that older age, smaller birth size and maternal poor nutritional status were most significant factors for high prevalence of malnutrition which was assessed using three standard anthropometric indicators, such as underweight, stunting and wasting each of two kinds severe and moderate, following the WHO guidelines and cut-off points. The variables that were associated with severe as well as moderate underweight and stunting were father’s poor education, household lower economic condition and division of residence. Mother’s poor education and increased age of household ...

However, the scales at which models can be developed, and the subsequent problems they can inform, are often limited by our inability or challenges to effectively understand data that mimic interactions at the finest spatial, temporal, or organizational resolutions. Linear regression analysis is the one of the widely used methods for investigating such relationship between variables. Multicollinearity is one of the major problem in regression analysis. Multicollinearity can be reduced by using the appropriate regularized regression methods. This study aims to measure the robustness of regularized regression models such as ridge and Lasso type models designed for the high dimensional data having the multicollinearity problems. Empir...

Data from the Demographic and Health Survey Bangladesh were used to evaluate the influences of several significant socioeconomic, demographic, health system and community factors on the current status of malnutrition among 5333 under-5 years children. Results reveal that older age, smaller birth size and maternal poor nutritional status were most significant factors for high prevalence of malnutrition which was assessed using three standard anthropometric indicators, such as underweight, stunting and wasting each of two kinds severe and moderate, following the WHO guidelines and cut-off points. The variables that were associated with severe as well as moderate underweight and stunting were father’s poor education, household lower economic condition and division of residence. Mother’s poor education and increased age of household ...

In this paper an attempt is made to estimate the elasticity of substitution^) for the manufacturing sector of Bangladesh and compare them with those of other countries. While estimating the elasticity of substitution we shall compare the results obtained by different models which will provide a test of sensitivity of those estimates to the underlying assumptions of the models.

However, the scales at which models can be developed, and the subsequent problems they can inform, are often limited by our inability or challenges to effectively understand data that mimic interactions at the finest spatial, temporal, or organizational resolutions. Linear regression analysis is the one of the widely used methods for investigating such relationship between variables. Multicollinearity is one of the major problem in regression analysis. Multicollinearity can be reduced by using the appropriate regularized regression methods. This study aims to measure the robustness of regularized regression models such as ridge and Lasso type models designed for the high dimensional data having the multicollinearity problems. Empir...
