Abstract: Background: Noise is one of the most important forms of environmental pollution among developed and developing countries. A report from UK National Study of Hearing estimated that around 440 million people suffer from noise induced hearing loss in EU countries with 1-1.6 million disability-adjusted life year lost. In China, the Second China National Sample Survey on disability in 2007 revealed that about 27.8 million people suffered from hearing impairment, and 73.4% of which (about 20 million) were diagnosed with disability. The prevalence of hearing impairment was estimated to be 2.1% in the general population, and increased to 11.0% among those aged greater than 65 years. Objective: To find out the effect of earplug on noise induced hearing loss (NIHL), as well as understanding the source and exposure of noise in the industry, to estimate the prevalence of NIHL in factories with noise exposure, to analyze relationships between NIHL and age, sex, dose and duration of occupational noise exposure, type of work, use of hearing protection products, education level and other factors. Significant risk factors identified were used to provide evidence-based recommendations in prevention and control of NIHL. Study Design: Retrospective, cross-sectional study Method: A total of 1874 workers exposed to noise in a compressor factory in Guangzhou, China were included. Between September 2011 and January 2012, physical examination including a screening program of hearing loss, pure tone audiometry test were carried out among workers including information on age, sex, work types, noise exposure level, exposure time, as well as the questionnaire about earplug using status, status of using ear products report by company, smoking status, education level, discharge of ear, history of herpes zoster, history of using ototoxic drugs, history of ear surgery, family history of NIHL, systolic blood pressure, diastolic blood pressure. The outcome variable is the audiometric mean value which reflects hearing status of the subjects. Subgroup differences in mean value of audiometry were compared by independent sample t-test. Multiple linear regression and logistic regression models were used to evaluate associations between earplug use and NIHL, adjusted for other potential confounders. Factors associated with earplug use were also identified. Result: 1873 workers took part in the study (both physical examination and questionnaire) The prevalence of NIHL is 381 (20.3%) from study, and an average noise level of 83.5 dB was detected in the factory across different types of working place. The pure tone audiometric mean value (PTA) is 26.7 dB with a standard deviation of 4.8. The mean PTA value for those using earplug is 25.81 dB, which was significantly lower than those not using earplug with a mean PTA value of 1.54 dB (p Multiple linear regression model showed a dose response effect in use of earplug on NIHL, with an estimated mean PTA 1.49 dB (p-value

This book was released on 2019-11-18 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the early success of some articles as author and co-author, Dr Win Tin has come up with his first book on Noise-Induced Hearing Loss and the Hidden Society Burden. He noticed that everyone needs peace of mind, especially after a long working day. We need to rest, physically and mentally to recoup, working again with enthusiasm the next day. Thus, it is important that we have a certain private, quiet, peaceful serene environment, day or night. But noise is all around us. The sound of grass cutters, the piling of structures nearby, children playing and shouting, or the traffic noise. These can make a lot of noise and the peace shattered. Noise-induced hearing loss is mainly caused by a certain amount of noise which has a deleterious effect on the ear when exposed to long periods of time e.g. years, and usually without the person noticing, as in occupational noise-induced hearing loss or single instances of extreme noise, as in acoustic trauma. This causes not only hearing loss but effects socially, financially, physically and mentally. Its problem is so big with compensation in millions, causing a huge hidden burden to the society, people and government. Yet it should be noted that this is the only preventable cause of sensorineural hearing loss, which can be prevented, while other causes are still not possible. The book introduces various noise, the pathogenesis and causes of noise-induced hearing loss, as seen in various strata of people. Apart from this, there is the Malaysian perspective as written by some researchers from Malaysia. Then there are also effects of noise not only on humans but also in birds and fish. Methods to diagnosis and ways to prevent, with up-to-date researches and treatment are also discussed. Thus, it is a comprehensive one for the knowledge of all levels, professionals and non-professionals. This book is important, and everybody should read or keep as a reference, as they will know in-depth, as most are unaware of the hidden problem. Young people, military, hospital workers, nurses, contractors, builders, architect, engineers, urban planners, public health doctors and everyone can benefit from this book. Hence, this book is useful not only for leisure reading but cherished for life. With the 25th anniversary of UMS, this book can be a milestone, for the wellness of UMS staff and people of Sabah.

Download or read book Corporate Responsibility Coalitions written by David Grayson and published by Routledge. This book was released on 2017-09-08 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significance of business-led corporate responsibility coalitions is indisputable. The WBCSD has 200 member companies with combined annual revenues of US$7 _trillion_; the UN Global Compact has almost 8,000 corporate members, over two-thirds of them from developing countries. It is estimated that there are more than 110 national and international generalist business-led CR coalitions. But there is now urgent need for informed and balanced analysis of their achievements, their progress and their potential. Why did these coalitions start and grow? What have been their impacts? Where are they heading now? Where should they be going? What is the future? In a period of austerity, the business and public sector must decide whether funding these coalitions is a priority. To meet current crises, there will have to be a great deal more business involvement; but efforts of individual corporations will not be sufficient. There is also a need for far more collective action among companies and more collaborative action between different sectors of society. Business-led CR coalitions with their decades of convening experience could play an important role in this process - if they are fit for purpose going forward. Authors David Grayson and Jane Nelson have been actively involved in such coalitions for decades. In Corporate Responsibility Coalitions they first explore the past, present and future of these coalitions: the emergence of new models of collective corporate action over the past four decades; the current state of play, and the increasing number, diversity and complexity in terms of how they not only network with each other but also engage in a much broader universe of institutions that are promoting responsible business practices. In addition, the book provides in-depth profiles of the most strategic, effective and long-standing coalitions, including: Business for Social Responsibility; Business in the Community; CSR Europe; Instituto Ethos; International Business Leaders Forum; the UN Global Compact; and the WBCSD. This book will be required reading for key supporters and potential partners of such coalitions in companies, governments, international development agencies, foundations, non-governmental organizations, academic institutions and think-tanks. It also aims to inspire a future generation of leaders to be more aware of the role of business as a partner in driving more inclusive, green and responsible growth, and to help them develop new types of leadership skills so that they can be effective in finding multi-stakeholder solutions to complex and systemic challenges.

Download or read book Shooting Incident Reconstruction written by Michael G. Haag and published by Academic Press. This book was released on 2011-06-29 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shooting Incident Reconstruction, Second Edition, offers a thorough explanation of matters from simple to complex to help the reader understand the factors surrounding ballistics, trajectory, and shooting scenes. Forensic scientists, law enforcement, and crime scene investigators are often tasked with reconstruction of events based on crime scene evidence, along with the subsequent analysis of that evidence. The use and misuse of firearms to perpetrate crimes from theft to murder necessitates numerous invitations to reconstruct shooting incidents. The discharge of firearms and the behavior of projectiles create many forms of physical evidence that, through proper testing and interpretation by a skilled forensic scientist, can establish what did and what did not occur. Written by the world's most well-respected shooting scene and ballistics experts, the book addresses the terminology, science, and factors involved in reconstructing shooting incident events to solve forensic cases. It covers the full range of related topics including: the range from which a firearm was discharged; the sequence of shots in a multiple discharge shooting incident; the position of a firearm at the moment of discharge; and the position of a victim at the moment of impact. The probable flight path of a projectile and the manner in which a firearm was discharged are also discussed. Case studies illustrate real-world application of technical concepts, supported by over 200 full-color diagrams and photographs. This book will be of value to practicing forensic scientists (firearm and toolmark examiners), ballistics experts, crime scene personnel, police departments, forensic consultants (generalists), attorneys and judges, medical examiners (coroners), and forensic pathologists. - Written by the most well-respected shooting scene and ballistics experts in the world - Contains over 200 full-color diagrams and photographs that support and illustrate key concepts - Case studies illustrate real-world application of technical concepts
