A human-oriented design process for collaborative robotics
The potential of collaborative robotics often does not materialize in an efficient design of the human-robot collaboration. Technology-oriented approaches are no longer enough in the Industry 4.0 era. This work proposes a set of methods to support manufacturing engineers in the human-oriented design process of integrated production systems to obtain satisfactory performance in the mass customization paradigm, without impacting the safety and health of workers. It founds the design criteria definition on five main pillars (safety, ergonomics, effectiveness, flexibility, and costs), favors the consideration of different design alternatives, and leads their selection. The dynamic impact of the design choices on the various elements of the system prevails over the static design constraints. The method has been experimented in collaboration with the major kitchen manufacturer in Italy, which introduced a collaborative robotics cell in the drawers' assembly line. It resulted in a more balanced production line (10% more), a verified risk minimization (RULA score reduced from 5 to 3 and OCRA score from 13.30 to 5.70), and a greater allocation of operators to high added value activities
Tools and Methods for Human Robot Collaboration: Case Studies at i-LABS
The collaboration among humans and machines is one of the most relevant topics in the Industry 4.0 paradigm. Collaborative robotics owes part of the enormous impact it has had in small and medium size enterprises to its innate vocation for close cooperation between human operators and robots. The i-Labs laboratory, which is introduced in this paper, developed some case studies in this sense involving different technologies at different abstraction levels to analyse the feasibility of human-robot interaction in common, yet challenging, application scenarios. The ergonomics of the processes, safety of operators, as well as effectiveness of the cooperation are some of the aspects under investigation with the main objective of drawing to these issues the attention from industries who could benefit from them
Learning impact of education during pulmonary rehabilitation program. An observational short-term cohort study
Background: Among the several components integrating a pulmonary rehabilitation (PR) course, education may contribute to the individual\u2019s recognition of symptoms and worsening of the disease. However, the specific gain of education is far to be clearly documented to the health care providers. Aim of our preliminary study was to assess the learning impact of educational sessions (ES) in Chronic Obstructive Pulmonary Disease (COPD) patients referred to standard PR.Methods: Six ES on 3 areas (Symptoms-Therapies, Aids, Mood) were applied during PR at our clinic. The learning effect was prospectively evaluated by a specific questionnaire (ESQ) in 285 COPD patients (age 69\ub18 years, FEV1 53\ub114 % pred), then grouped into those who have completed ES (Completers group, n=226) or who did not (mean 2\ub11 ES) (Control group, n=59). Total and partial ESQ scores, and PR outcomes (6-minute walking test-6MWD, effort-dyspnoea at Medical Research Council scale-MRC, and health-related quality of life scale-SGRQ) were assessed in a pre (T0) to post (Tend) design.Results: Similar improvement in PR outcomes was recorded in both groups at Tend, whereas ESQ total and partial scores significantly increased in Completers only (p<0.001). ESQ-Aids score improved to a greater extent in Completers than in Control (+0.60\ub11.03 vs +0.27\ub11.27 point respectively, p=0.036). A higher proportion of Completers improved above the median change of both ESQ total and aids scores (p<0.05).Conclusion: Attending educational sessions produces a specific short-term learning effect during rehabilitation of COPD patients

Mitochondrial Function in Antarctic Nototheniids with ND6 Translocation
Fish of the suborder Notothenioidei have successfully radiated into the Southern Ocean and today comprise the dominant fish sub-order in Antarctic waters in terms of biomass and species abundance. During evolution in the cold and stable Antarctic climate, the Antarctic lineage of notothenioids developed several unique physiological adaptations, which make them extremely vulnerable to the rapid warming of Antarctic waters currently observed. Only recently, a further phenomenon exclusive to notothenioid fish was reported: the translocation of the mitochondrial gene encoding the NADH Dehydrogenase subunit 6 (ND6), an indispensable part of complex I in the mitochondrial electron transport system
Draft genome assembly and transcriptome data of the icefish Chionodraco myersi reveal the key role of mitochondria for a life without hemoglobin at subzero temperatures
Antarctic fish belonging to Notothenioidei represent an extraordinary example of radiation in
the cold. In addition to the absence of hemoglobin, icefish show a number of other striking
peculiarities including large-diameter blood vessels, high vascular densities, mitochondriarich
muscle cells, and unusual mitochondrial architecture. In order to investigate the bases of
icefish adaptation to the extreme Southern Ocean conditions we sequenced the complete
genome of the icefish Chionodraco myersi. Comparative analyses of the icefish genome with
those of other teleost species, including two additional white-blooded and five red-blooded
notothenioids, provided a new perspective on the evolutionary loss of globin genes. Muscle
transcriptome comparative analyses against red-blooded notothenioids as well as temperate
fish revealed the peculiar regulation of genes involved in mitochondrial function in icefish.
Gene duplication and promoter sequence divergence were identified as genome-wide patterns
that likely contributed to the broad transcriptional program underlying the unique
features of icefish mitochondria
