However, due to the low literacy and awareness rates among rural population of Bangladesh, the service is not much effective. This paper represents a study on the awareness of the rural population of telemedicine service in Bangladesh and few key findings indicate how the awareness could be increased. The research also suggests that utilizing blockchain technology can enhance the data security and privacy. The research reveals some of the findings which can raise the awareness and popularity of telemedicine service among rural population. We have proposed implementation of blockchain technology which can vastly improve the security issue.

In developing countries like Bangladesh, disease classification process mostly remains manual, time consuming and sometimes erroneous. Designing an E-health system comprised of disease identification model would be a great aid in such circumstances. The automation of identifying the diseases with the help of machine learning will be more accurate and time-saving. In this paper, Decision Tree, Gaussian Naive-Bayes, Random Forest, Logistic Regression, k-NN, MLP, and SVM machine learning techniques are applied for three diseases: Dengue, Diabetes, and Thyroid. MLP for Dengue, Logistic Regression for Diabetes, and Random Forest for Thyroid performed the best with accuracies of 88.3%, 82.5%, and 98.5% respectively. Additionally, a medical specialist recommendation model and a medicine suggestion model are also integrated in the proposed E-Health system.

We compared the efficacy of endoscopic duodenal stent placement with that of gastrojejunostomy for treating patients with pancreatic cancer who are candidates for intensive combination chemotherapies as the first line of treatment. Methods This retrospective observational study included 100 patients from 18 institutions in Japan. Inclusion criteria were as follows: (1) cytologically or histologically confirmed adenocarcinoma of the pancreas, (2) good performance status, (3) gastric outlet obstruction scoring system score of 0–1 and (4) no history of treatment for pancreatic cancer. Results There was no significant difference in the background characteristics of patients in the endoscopic duodenal stent placement (n = 57) and gastrojejunostomy (n = 43) groups. The median overall survival in the endoscopic duodenal stent placement and...

It results in better properties than those of the individual components used alone. In contrast to metallic alloys, each material retains its separate chemical, physical, and mechanical properties. By combining materials different properties of the materials can be enhanced to a desired limit. The two constituents are known as reinforcement and matrix. The main advantages of composite materials are their high strength and stiffness. They also have the property of low density, when compared with bulk materials, allowing for a weight reduction in the finished part.

Human Factors (HFs) experts and ergonomists are employed in various companies including oil and gas industries. However, it is a great challenge how these professionals contribute their skills to the design of products and systems that are ethically standard. There is also a need to ensure that the workers are safe and healthy in a productive environment. The choices of individuals practising HFs should thus be encouraged through the concept of professional liability, accountability and ethics that tell about the best practice we must do things as an ergonomist or behave properly to be HFs expert. It is about how our practices impact our society, and how we should be liable to our work. In terms of professional accountability and liability, we are facing tremendous challenges in our profession. As HFs experts, we are practicing to deal wi...

Most scientists accept the neurological impact of the infection are indirect and after that effect of either oxygen starvation to the cerebrum (the "upbeat hypoxia" showed by numerous patients), or the result of the body’s inflammatory response (the popular "cytokine storm"). Researchers believe the neurological effects are “cytokine-mediated”.

S i n c e w e l i v e i n a s o c i e t y w h i c h i s o r g a n i s e d predominantly along daytime activity, therefore working in the night shift may deeply disrupt our social and family life. It is also a well-known fact that night shift causes fatigue and circadian disruption. The basic manifestation of fatigue and circadian rhythm has been linked to health a n d s a f e t y pr o b l e ms , i n v o l v i n g d e c r e m e n ts i n psychophysical and physiological functions, plus subjective complaints. In this context quantitative relationships between shift work and circadian rhythm need to be assessed to explore suitable time schedule, and to minimise sleep depth and fatigue. There is also a great need to discuss circadian disruption, sleepiness and the increasing cost of work related illness among night workers. In this regard, some aspects of fatigue and circadian disruption caused from night shift work are revealed in this paper aiming to increase workers' health, safety and well being as well as productivity. Light / dark cycle and social stimuli issues acting on the circadian timing systems are also explored to solicit opinions and discussion on the controversy of night work. Suggestions are therefore likewise given to enhance workers' adaptation to night shift and synchronization process.

An assistive device usually provide alternatives to functional limitations imposed by the client's disorder, and thereby minimising rehabilitation costs. It is therefore important to know about how assistive technology will function in all the po ssible as pects of su ch di sabili ti es and impairements. When designing a technical device, particularly in conjunction with the target user group, ergonomic issues are therefore important to find out the extent to which an assistive device is convenient or not, and to check the quality performance of assistive technology. Since the question of the match or mismatch of an assistive device and a disabled person requires much attention, it is therefore suggested that paying attention on how an assistive device be ergonomically designed and developed is important. Ergonomic applications are to be applied for increasing motivation of prospective customers through innovative performance of AT. The authors believe that there are opportunities in ergonomic applications to manufacture an assistive device as unique, cost saving, and allows less exertation and reduces energy consumption when it is used. Hence this paper highlights human factors and/or ergonomics consideration in the process of design and development of assistive devices synchronising with gerontechnological research and development aiming to emphasise user's requirement.

The intention of making a house in such a way that it solves basic problems of fixture and fittings. However the construction phase of a good house is a critical to design inside and outside structures. Often the builders do not know all the factors to be considered that can maintain a safe, hygienic and healthy environment. It is believed that when housing is ergonomically furnished, then a maximum benefit will be achieved. To meet with an individual's specific needs, an analysis of user's requirement is the most important factors to be considered in the design of special houses. Users' data such as anthropometric dimension, users' choices and preferences are also necessary to design a suitable living environment. In this regard, this paper illustrates some ergonomic features to design and develop good houses in terms of how people with restricted mobility and communication can truly be helped residing in their homes and performing their daily living activities. Users' social, medical and engineering needs are highlighted following the process of disability, ageing, or impairments to achieve the maximum level of benefits, and ensuring safe and sound living.
