Four studies conducted in the light metal, electrotechnical and printing industries are described. The purpose was to determine the applicability of the systems approach to occupational accidents. The data consisted of 291 accidents and 701 controls. The stable characteristics of the workers or the environments were not good predictors of accidents. The clearest differences between the accident...

3D Printing In article number 2202204, Daeha Joung and co-workers present a printed magnet-infused origami platform for cell culture assessments. The enables spatiotemporal control of activities planar vertical proliferation cells in microchannels. This system can propel higher-order capturing conditions at an appropriate scale.
AIMS To quantify occupational ill health resulting from dermatitis in the UK printing industry and to explore links with particular processes and activities. METHODS Approximately 2600 members of the Graphical, Paper and Media Union living in Nottinghamshire were sent a self completion questionnaire. A sample of respondents, both those who reported current skin problems and those who did not,...
Objectives-After an inquiry from the employees of an offset printing plant, a historical cohort study was conducted to investigate cancer mortality among these workers. Methods-The cohort comprised 262 men, who contributed 2771 person-years of observation. 16 deaths were identified during the follow up period (1980-91). Expected numbers of deaths were derived from age specific regional rates. S...
background and objectives: exposure to contaminated needlesticks and sharp devices is an important occupational hazard among healthcare workers. the objective of this study was to gain further insight into prevalence and risk factors of needlestick and sharps injuries among healthcare workers. methods: a cross-sectional survey was carried out among 384 healthcare workers of two hospitals in ne...
One of the challenges in the printing industry is the presence of extra lines in printing design. This problem is due to the improper surface roughness of carved cylinders. This research endeavors to specify and optimize the effective parameters on the surface roughness of chrome coated printing cylinders in the finishing process that is done using a finish star machine. Investigated parameters...
Biofabrication In article number 2101309, Norbert Radacsi and co-workers show that the combination of electrospinning with 3D printing can create scaffolds suitable for cell growth. The electrospun nanofibers help to attract cells due their extracellular matrix-like structure, while 3D-printed parts serve as macroscopic structure material.
