    The Ministry of Republic Indonesia launched in 2015 as the national safety culture that every industrial sector was required to implement the safety culture as well. One of the effort to create safety culture in the companies with cultivating the behavior for using personal protection equipment at work. Cooper an expert of safety management explained there were three elements forming safety culture, psychological, behavior, and organization and situation aspect. The main purpose was to analyze the relationship between psychological aspect of workers and organization and a situation aspect with the behavior for using PPE. This is an observational analytic study with cross sectional approach. Data were analyzed with univariate and bivariate. Sample of this research were 25 workers from 32 population that gets by simple random sampling method. Data were collected by questionnaire and observation then analyze in descriptive and use cross tabulating and correlation spearmen test to obtain relationship between variables. The result showed that most of the workers (56%) have low behavior on PPE USAge. There almost all workers have a good motivation and clarified that availability and training about PPE was fair. There were significant correlation between motivation and training with complience of using PPE. Higly recommendation for company to increase the motivation for workers by apply a reward system

    Aims: The interactions of velocity scales on the Sun's surface, from granulation to supergranulation are still not understood, nor are their interaction with magnetic fields. We thus aim at giving a better description of dynamics in the mesoscale range which lies between the two scales mentioned above. Method: We analyse a 48h high-resolution time sequence of the quiet Sun photosphere at the disk center obtained with the Solar Optical Telescope onboard Hinode. The observations, which have a field of view of 100 \arcsec×\times 100 \arcsec, typically contain four supergranules. We monitor in detail the motion and evolution of granules as well as those of the radial magnetic field. Results: This analysis allows us to better characterize Trees of Fragmenting Granules issued from repeated fragmentation of granules, especially their lifetime statistics. Using floating corks advected by measured velocity fields, we show their crucial role in the advection of the magnetic field and in the build up of the network. Finally, thanks to the long duration of the time series, we estimate that the turbulent diffusion coefficient induced by horizontal motion is approximately 430km2s−1430 \mathrm{km}^2 \mathrm{s}^{-1}. Conclusions: These results demonstrate that the long living families contribute to the formation of the magnetic network and suggest that supergranulation could be an emergent length scale building up as small magnetic elements are advected and concentrated by TFG flows. Our estimate for the magnetic diffusion associated with this horizontal motion might provide a useful input for mean-field dynamo models.Comment: to appear in A&A - 8 pages, 13 figures (degraded quality) - Full resolution version available @ http://www.ast.obs-mip.fr/users/rincon/hinode_roudier_aa09.pd
