‘I need a break’: The Effect of Choice of Rest Break Duration on Vigilance

Introduction: Work-related fatigue on workers are usually caused by some factors such as individual characteristics (age, work period, nutritional status) and rest break. This research aims to analyze the correlation between individual characteristics and rest break with work-related fatigue on telecommunication network service workers. Method: This research used an observational analytic and a cross-sectional approach. The population and sample in this research were all 32 workers at I-OAN unit in a telecommunication network service company. The independent variables in this study were age, work period, nutritional status, and rest break, while the dependent variable was work-related fatigue. Data were obtained throughquestionnaires about individual characteristics (age, work period, nutritional status) and rest break filled by workers. The data were also obtained through the Industrial Fatique Research Committee (IFRC) questionnaires filled by workers. All of the data in this study were analyzed with the Spearman correlation test (α = 0.05). Results: The majority of I-OAN unit workers are in the age range of 25-29 years (46.9%), have 3-4 years of work period (56.2%), and have normal nutritional status (40.6%). For the rest break variable, there are16 workers (50%) who have <30 minutes rest break and also 16 workers (50%) who have ≥ 30 minutes rest break. Conclusion: There is a correlation between individual characteristics and rest break with work-related fatigue on telecommunication network service workers.Keywords: individual characteristics, rest break, work-related fatigue

Penelitian ini bertujuan mengetahui hubungan lama aktivitas fisik berat dengan Gejala Back pain pada penduduk usia kerja 18 – 55 tahun di wilayah Pulau Jawa dan Bali. Penelitian ini menggunakan data sekunder Survei Kesehatan Nasional Tahun 2001. Penelitian ini menggunakan desain potong-lintang dengan metode analisis regresi logistik ganda. Hasil penelitian mendapatkan ada hubungan antara aktivitas fisik berat dengan gejala back pain, setelah dikontrol oleh variabel-variabel confounding seperti lama aktivitas fisik duduk atau sedikit berjalan (terkait pekerjaan ataupun tidak), jenis kelamin, dan pendidikan. Responden dengan lama aktivitas fisik berat (bekerja 1-5 jam) memiliki risiko 2,03 kali untuk mengalami gejala back pain dibandingkan kelompok yang tidak melakukan aktifitas fisik berat (95% CI 1,34-3,08). Responden dengan lama aktivitas fisik berat (bekerja >5 jam) memiliki risiko 1,60 kali untuk mengalami gejala back pain dibandingkan kelompok yang tidak melakukan aktifitas fisik berat (95% CI 0,55 - 4,63). Disarankan untuk pemberlakuan regulasi waktu kerja menggunakan metode waktu rehat pendek (short rest break), dimana pekerja yang harus bekerja selama 5-6 jam terus menerus perlu diistirahatkan di pertengahan waktu tersebut selama sekitar 20 menit.Kata kunci: Aktivitas fisik, back painAbstractThe objective of this research is to investigate the relationship between high occupational physical activity with back pain symptoms among working age population (18—55 years olds) in Java and Bali islands. This research used secondary data from National Health Survey 2001. This research was using the crosssectional design and was analyzed by multiple logistic regression. The study result shows that there are a relationship between high occupational physical activity with back pain symptoms after controlled with confounding variables such as: duration of occupational sitting and short walk activity, duration of nonoccupational sitting and short walk, gender and educational status. Respondents with duration of heavy occupational activity of 1-5 hours have 2,03 higher risk to get back pain symptoms compared to those not doing it (95% CI 1,34-3,08). Respondents with duration of heavy occupational activity of >5 hours have 1,60 risk to get back pain symptoms compared to those not doing it (95% CI 0,55 - 4,63).Keywords : Physical activity, back pain

Rest Break

A framework is presented for modelling bud burst phenology of trees from the cool and temperate regions. Three ecophysiological aspects affecting the timing of bud burst are considered: (i) effects of environmental factors on the rest status of the bud, (ii) effect of rest status on the ability for bud burst, and (iii) direct effect of air temperature on the rate of development towards bud burst. Any model for bud burst phenology can be presented within the framework with three submodels, each of them addressing one of the corresponding three ecophysiological aspects. A total of 96 hypothetical models were synthesized by combining submodels presented in the literature. The models were tested in two experiments with saplings of Pinus sylvestris L. growing in experimental chambers at their natural site in eastern Finland. In the first experiment, air temperature and (or) concentration of atmospheric CO2 was elevated. Elevation of the air temperature hastened bud burst, whereas elevation of the concentration of CO2 did not affect it. Several models accurately predicted the timing of bud burst for natural conditions but too early for bud burst at the elevated temperatures. This finding suggests that (i) the risk of a premature bud burst with subsequent frost damage, as a result of climatic warming, was overestimated in a recent simulation study, and (ii) bud burst observations in natural conditions alone are not sufficient for the testing of these mechanistic models. Several models did predict the timing of bud burst accurately for all treatments, but none of them obtained sufficiently strong support from the findings to stand out as superior or uniquely correct. In the second experiment a photoperiod submodel for rest break was tested by exposing the saplings to short-day conditions. The short-day treatment had only a minor effect on the timing of bud burst. These results demonstrated the importance of the concept of model realism: the accuracy of a model can be lost in new conditions (e.g., global warming), unless the model correctly addresses the essential ecophysiological aspects of the regulation of timing of bud burst. Key words: annual cycle of development, chilling, dormancy, field test, photoperiod, rest break.
