Currently, metrology is an important element of any industry. Under these conditions, the accuracy of testing and calibration of measuring devices becomes critical. Due to the high accuracy of modern measuring instruments, human factor can play a significant negative role in the calibration process. Therefore, the use of modern tools, such as a data logger, can significantly improve the quality of the process, reducing staff functions to process control.

In machinery and equipment manufacturing industry, screw is an important part. Not only as a precision screw precision transmission components, but also commonly used for precision measuring devices. Precision screw itself directly affects the accuracy of precision machine tools and precision measuring instruments for transmission, positioning precision and accuracy, and thus the processing and inspection of precision screw is higher demanded. Traditionally, screw inspection is usually done by manual and the quality of inspection is not high, with very low inspection efficiency. To solve these problems, optimized system for screw inspection was designed and implemented. Using the Quartile range method in Statistics to remove outliers, and with the help of kalman filter, systemic error is got rid of. With these methods, raw measurement data is analyzed and processed, and inspection report is generated. The efficiency of screw inspection is highly improved.

The measurement process is the most important part of the production process in the industrial world. Obtaining good measurement results can not be separated from using measuring instruments that are always maintained. Subsequence, the maintenance of calibration procedures must be carried out periodically based on a predetermined time limit. The calibration process is an activity to compare standard quantities between measuring instruments and testers that are in accordance with the measuring instrument and carried out periodically. The implementation of the calibration process often has generates an uneven value where this value is better known as the uncertainty value. This research objective is to determine the uncertainty value of the measuring instrument of a dial indicator using the JIS B 7503 Standard. The calibration can control the quality of the equipment used, and can show whether the tool is feasible or not to be used.

In a global approach about the need of paying attention to staff working with and for older people with dementia and other diseases in residential care, it is necessary to investigate their emotional well-being to provide strategies to improve their quality of life and therefore their quality of patient care. Professional caregivers of people with dementia and other diseases have specific psycho-sociological problems. They are more prone to stress which can sometimes lead to the “burnout” due to specific functions in the workplace. To define the sample was decided to compare two residential centers of two regions, Murcia and Barcelona. We proceeded to the administration of the following measuring instruments: the scale Maslach Burnout Inventory (MBI) and an ad hoc survey conducted for professional caregivers. Finally, the results offer the possibility of carrying out programs to prevent emotional exhaustion in professional carers, as well as the possibility of designing psychoeducational programs for staff care and even future proactive and reactive interventions.

AbstractThis paper describes outcomes of the 2019 Cryo-EM Model Challenge. The goals were to (1) assess the quality of models that can be produced from cryogenic electron microscopy (cryo-EM) maps using current modeling software, (2) evaluate reproducibility of modeling results from different software developers and users and (3) compare performance of current metrics used for model evaluation, particularly Fit-to-Map metrics, with focus on near-atomic resolution. Our findings demonstrate the relatively high accuracy and reproducibility of cryo-EM models derived by 13 participating teams from four benchmark maps, including three forming a resolution series (1.8 to 3.1 Å). The results permit specific recommendations to be made about validating near-atomic cryo-EM structures both in the context of individual experiments and structure data archives such as the Protein Data Bank. We recommend the adoption of multiple scoring parameters to provide full and objective annotation and assessment of the model, reflective of the observed cryo-EM map density.

SummaryWe are still confronted by numerous different nosographic models and problems concerning the objective evaluation of patients progress during treatment. It is interesting to consider the consequences of this situation in psychiatry which still involves a relative diversity of practical methods used in clinical trials. The recommendations of the USA Food and Drug Administration, on the one hand, constitute a highly structured and precise reference. The World Health Organization, on the other hand, promulgates general recommendations resulting from a compromise designed to satisfy the greatest number of clinicians.Despite the apparently diverse principles and the different practical methods they propose, both those sets of recommendations have been useful in inspiring clinicians to reflect upon these different methodological approaches. The qualities of the inclusion criteria used in the study of patients and the sensitivity of the different measuring instruments have allowed psychotropic drug users as well as producers to recognize the need for a certain rigour in clinical trials.The FDA and WHO guidelines have certainly improved the quality of clinical trials in psychopharmacology. However, they also represent a source of resistance to innovation.A series of consensus meetings to first reconcile US and European points of view and later to include new techniques in the recognized sets of methods would therefore be helpful.

Abstract Background Home postpartum care is a major part of midwifery care in Germany. The user perspective plays an increasingly important role in the evaluation of health services, but there is a lack of valid and theoretically based measuring instruments, especially in midwifery care. The aim of this study was to develop and validate an instrument for measuring quality of midwifery care in the postpartum period from the perspective of women. Methods The following steps were taken to achieve this: (1) definition of the goals of midwifery work; (2) literature-based item development; (3) item selection based on a pre-test (n = 16); (4) item reduction and investigation of factor structure by means of explorative factor analysis (EFA; n = 133);(5) second EFA (n = 741) and confirmatory factor analysis (CFA; n = 744) based on a split representative sample survey; (6) hypothesis-based testing of correlations to sociodemographic characteristics of women and to characteristics of care. Results Measurement of Midwifery quality postpartum (MMAYpostpartum) consists of three scales with a total of 17 items which were found to have acceptable internal consistency: Personal Control (Cronbach’s alpha = .80), Trusting Relationship (Cronbach’s alpha = .87) and Orientation and Security (Cronbach’s alpha = .78). CFA verified and confirmed three factors: CFI = .928, TLI = .914, RMSEA = 0.073. Conclusion MMAYpostpartum is a predominantly valid, reliable short tool for evaluating the quality of midwifery care postpartum. It can be used to evaluate midwifery care, to compare different care models and in intervention research. It thus supports the orientation of midwives’ work towards the needs of women and their families.
