The study examined the ocular health of agricultural workers in the fisheries sub sector with the aim of establishing a possible correlation between the work place hazards and their ocular health. A multi-stage random sampling (involving 683 subjects, 358 fishmongers and 325 fishers) was employed. Ocular hazards encountered at the work place included seawater, sand or dust, heat, sunrays and smoke. Exposure to these hazards were found to be associated with ocular irritation (P<0.001), tearing (P<0.001), red eye (P<0.001), gritty sensation (P<0.001), blurred distant vision (P=0.001) and blurred near vision (P=0.001). The development of pterygium was associated with the exposure to sunrays (P=0.042) and heat (P=0.001) among fishmongers. Further analysis using multivariate logistic regression indicated exposure to heat as the most important predictive factor for pterygium (OR=1.951, P=0.003). Exposure to seawater was found to be associated with the development of cataract (P=0.022) among fishermen/fishers. Cataract among fishmongers was rather associated with exposure to heat (P=0.005), sunrays (P=0.035) and sand/dust (P=0.002). Exposure to work place hazards is associated with ocular disorders in the fishing industry of Ghana.

<p>Mental health becomes an major issue and has been of growing concern recently, but only few empirical studies focused on adolescence’s mental health especially in Aceh.  The current study aimed to determine the effect of sex, age, and religiosity on mental health among adolescents in Banda Aceh. A total of 342 students from four high school students in Banda Aceh was selected using Multi-Stage Cluster and Non-Proportionate Stratified Random Sampling. Mental health and religiosity were measured using Mental Health Inventory adapted from Veit and Ware, and Religiosity Scale developed by researchers from Muslim religiosity theory by Hamzah et al., respectively.  Data was analyzed using multiple regression analysis. Result of the study found that religiosity was significantly contributed to adolescents’ mental health (β=0,29, p&lt;0.01), indicated that higher score on religiosity scale was followed by higher score on mental health. Meanwhile, sex (β=-0,04, p&gt;0,05) and age (β=0,04, p&gt;0,05)  did not predict mental health in the present study. It showed that a sense of connectedness to God and higher level of religious involvement play an important role on adolescents’ mental health. Findings of the study give a valuable information  for the development of mental health promotions for adolescents, particularly in Banda Aceh.</p>

The Impact

This Note will discuss the impact of random sampling at elections conducted under the single transferable vote (STV) electoral system in multi-member constituencies in the Republic of Ireland. STV, partly because of its popularity among electoral reformers, has received considerable theoretical scrutiny. It has been given an ‘intermediate’ rating in recent assessment of a number of electoral systems, and dismissed as a ‘perverse social choice function’ because it is subject to non-monotonicity. This shortcoming is also mainly responsible for the low degree of acceptance accorded to it by Brams and Fishburn. Nurmi concludes that STV (like other multi-stage systems) performs poorly, with regard to a number of criteria, in comparison with one-stage systems like approval voting. Black complains that STV ‘is a compound of minor complexities and is difficult to remember’. Others have discussed shortcomings in STV and suggested remedies which can be implemented where the counting of votes is entirely computerized.

Introduction. Building materials industry, including the production of clay and ceramic building bricks, cement, concrete products, saw building stone, sawn wood, granite blocks and rubble, is one of the most important economy units, prompting authors to generalize research data about working conditions and the incidence of occupational diseases in the main production building materials industry/ The data were accumulated during many years. Material and methods. Research methods included a comprehensive study of the working conditions of employees at enterprises of construction materials industry, followed by in-depth periodic medical examination. Then, with statistical methods (determination of the confidence interval index of the binomial distribution) calculated confidence interval for the prevalence of patients with an established diagnosis of occupational diseases in similar enterprises. Results. Results of 40-years research on occupational hazards parameters and physical examination of workers employed at productions of clay and ceramic bricks, cement, armed concrete, saw building stone, lumber wood, granite blocks crush stone were summarized because of the absence of complex estimation of work-place conditions and incidence of occupational diseases in main production of building materials industry. Typical occupational hazards were established for the every production. Many productions show the greatest disadvantage concerning levels of physical overload that was neglected by specialists in occupational health and safety for many years. The prevalence of patients suffering from chronic occupational diseases was predicted for employees of investigated productions and the most relevant forms of occupational pathology were determined. About 7.7% of workers in investigated productions appeared to suffer from occupational diseases that were not timely diagnosed. This figure is approximately 10 times higher than official statistics. The dependence of the prevalence of patients with occupational diseases from the level of technological modernization of production was revealed. If we can accept the proportion of patients with occupational diseases among employees working in the complex automated production (the highest degree of organization of labor) for referent unit than at the enterprises with the other technologies the proportion will be different: automated production - 10, mechanical work - 4, mechanical hand work - 5, hand work - 3.
