Donning protective clothing for mitigation of hazard from chemical agents poses a problem in the form of heat stress. When choosing protective clothing, many factors must be taken into account including insulative properties and evaporative resistance. This study calculated and compared Re,T,a for three clothing ensembles at levels of heat stress past the level of compensation for heat gain to determine if Re,T,a values varied or remained the same with changes in heat stress level. A three-way mixed model analysis of variance demonstrated significant differences for estimated Re,T,a values among ensembles, heat stress levels and interactions among ensembles and heat stress levels (p < 0.0001). A significant interaction between heat stress levels and ensembles was identified (p<0.05). The results of the study indicated that Re,T,a values are affected by levels of heat stress such that increasing levels were associated with lower values of Re,T,a. The study also helped to illustrate that Re,T,a values are not a constant associated with clothing, walking speed, and air speed.

Following a review of the stress, distress and coping reported by student health professionals and students in higher education, see Chapters 2 and 3, the hypothesis that a problem existed with distress early in training was confirmed by screening two cohorts of first year student nurses, see Chapter 4. Some 50.5% of students, in Cohort one (N=109, Week 40) and 67.9% of students in Cohort two (N=111, Week 24) suffered significant levels of affective distress. All students were enrolled on the newly implemented 1992 scheme of nurse education in Tayside. The underlying dimensions of situational sources reported by student nurse stress were clarified with the development of the Student Nurse Stress Index, see Chapter 5. A reliable 22 variable solution with oblique structure and non-orthogonal factors of &quot;academic load&quot;, &quot;clinical sources&quot;, &quot;intet/ace worries&quot;, &quot;personal problems&quot; was obtained. This measure showed cross sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions. A stress reduction/management intervention set at individual and interface levels, designed to reduce levels of student nurse distress revealed by the earlier screening study, was implemented during a second series of hospital placements, see Chapter 6. A randomised controlled trial revealed the success of this programme in reducing affective distress in 73 student nurses shown to have experienced significant levels of distress earlier in training. A series of significant treatment x time interactions were found with a range of context-free measures of affective distress, e.g. General Health Questionnaire-30 (Goldberg, 1972), State and Trait Anxiety Inventory (Speilberger, et aI., 1983), Beck Depression Inventory (Beck, et aI., 1987), with situational sources of stress (Beck &amp; Srivastava, 1991), and Domestic Satisfaction (Derogatis, 1980). Similar treatment x time interactions were found with Direct Coping (Parkes, 1984), and Relaxation Potential (Derogatis, 1980). Adaptive changes were confmed to the experimental group alone. In addition, State Anxiety on the morning of an important exam was lower for students receiving stress management (Treatment X= 45.88, Control X =59.09). The intervention had no detectable effect on organisational variables of sickness, absence and examination performance. However, logistic regression and hierarchical multiple regression analysis showed that initial distress at screen did not predict pre or post-treatment changes in sickness or absence, or subsequent examination performance. Stress management delivered in groups reduced affective distress and increased adaptive coping use in both clinical and academic settings. Possible future directions for this research targeting student nurses are outlined in Chapter 7.

Thesis (M.Tech.: Environmental Health)-Dept. ofEnvironmental Health, Durban Institute of Technology, 2005 xv, 144 leaves ; 30 cm / Motivation: Lower back pain (LBP) has been found to affect workers and often result in higher costs to industry than any other musculoskeletal disorder. Traditionally, the most widely investigated risk factors for LBP have been biomechanical demands of the job. By examining LBP, both its prevalence and distribution, it becomes possible to focus on contributory risk factors that bring on its onset. Aim: To identify the selected risk factors associated with prevalence of LBP amongst refuse truck drivers in the eThekwini Municipality, and to evaluate the relationship between the selected risk factors and the prevalence of LBP.
