Occupational hazard in Malaysian traffic police: special focus on air pollutants

This paper provides a specific deliberation on occupational hazards confronted daily by Malaysian Traffic Police. Traffic police is a high-risk occupation that involves a wide range of tasks and, indirectly, faced with an equally wide variety of hazards at work namely, physical, biological, psychosocial, chemical, and ergonomic hazards. Thereupon, occupational injuries, diseases, and even death are common in the field. The objective of this paper is to collate and explain the major hazards of working as Malaysian traffic police especially in Point Duty Unit, their health effects, and control measures. There are many ways in which these hazards can be minimised by ensuring that sufficient safety measures are taken such as a wireless outdoor individual exposure indicator system for the traffic police. By having this system, air monitoring among traffic police may potentially be easier and accurate. Other methods of mitigating these unfortunate events are incorporated and addressed in this paper according to the duty and needs of traffic police.

The conceptualization of depression among Filipino seafarers

The Center for Epidemiological Studies – Depression (CES-D) scale is a well-validated and frequently used measure for assessing symptoms associated with depression. This scale was developed primarily on the basis of American populations, however, and previous research has suggested that the original factor structure may not be appropriate for all populations. One such population is the Filipino population. This study represents the first study we are aware of to examine the factor structure of the CES-D scale in a sample of Filipino seafarers. Seafaring is considered a high stress and high risk occupation. Based on data collected from 135 Filipino seafarers, we conducted factor analyses to identify the appropriate factor structure for the CES-D in this population. We found that a three-factor structure better described the responses of Filipinos in our sample than the standard four-factor structure. The Filipino factor structure appears to collapse depressive affect and somatic factors found in previous research, while including a specific factor of social-focused symptoms of depression. This structure maintains the positive affect factor found in previous work. Implications of this for clinical psychology assessment and practice in the Philippines are discussed.

Voice Disorders in Teachers

Voice disorders are a common occupational hazard of teaching school. This article provides an overview of recent epidemiological research surrounding this high-risk occupation, identifies possible mechanisms contributing to voice disorder development including vibration overdose, summarizes recent clinical trials research evaluating treatments for teachers with voice disorders, and discusses primary prevention and the relative inadequacy of “education only” approaches.

Risk of hepatitis B virus in the slaughter house

The study involved 180 Nigerian butchers and 180 traders (controls) selected by multistage stratified sampling who had their sera assayed for HBsAg (hepatitis B surface antigen) by enzyme-linked immunosorbent assay method. The butchers and the controls had an HBsAg sero-prevalence rate of 9.4% and 3.3%, respectively. Various risky practices were more common among the butchers but their hepatitis B antigenaemia was not related to the duration of their occupational exposure. The study shows that the butchers constitute a high risk occupation for hepatitis B viral infection.
