AbstractManufacturers and laboratories might benefit from using a modern integrated tool for quality management/assurance. The tool should not be confounded by commutability issues and focus on the intrinsic analytical quality and comparability of assays as performed in routine laboratories. In addition, it should enable monitoring of long-term stability of performance, with the possibility to quasi “real-time” remedial action. Therefore, we developed the “Empower” project.The project comprises four pillars: (i) master comparisons with panels of frozen single-donation samples, (ii) monitoring of patient percentiles and (iii) internal quality control data, and (iv) conceptual and statistical education about analytical quality. In the pillars described here (i and ii), state-of-the-art as well as biologically derived specifications are used.In the 2014 master comparisons survey, 125 laboratories forming 8 peer groups participated. It showed not only good intrinsic analytical quality of assays but also assay biases/non-comparability. Although laboratory performance was mostly satisfactory, sometimes huge between-laboratory differences were observed. In patient percentile monitoring, currently, 100 laboratories participate with 182 devices. Particularly, laboratories with a high daily throughput and low patient population variation show a stable moving median in time with good between-instrument concordance. Shifts/drifts due to lot changes are sometimes revealed. There is evidence that outpatient medians mirror the calibration set-points shown in the master comparisons.The Empower project gives manufacturers and laboratories a realistic view on assay quality/comparability as well as stability of performance and/or the reasons for increased variation. Therefore, it is a modern tool for quality management/assurance toward improved patient care.

AbstractThis is a brief compilation of criteria on analytical quality that are prerequisites for the establishment and use of reference intervals in laboratory medicine. In this context, analytical quality is characterized by the precision, accuracy and long-term stability of laboratory methods performed with diagnostic kits, including their application on various instrument platforms. Systematically, analytical quality can be differentiated into quality of the method and its performance, and quality of long-term use. Factors influencing these types of quality in the development of diagnostic kits are discussed. The responsibility for maintaining analytical quality is shared by the two parties involved in the provision and use of reference intervals: The manufacturers of diagnostic kits are committed to providing complete description and traceability of their methods, whereas users must consider the effects of physiological, biometrical, preanalytical and analytical influences on the reference interval.

Abstract. This paper assesses the quality of IASI/Metop-A (IASI-A) and IASI/Metop-B (IASI-B) ozone (O3) products (total and partial O3 columns) retrieved with the Fast Optimal Retrievals on Layers for IASI Ozone (FORLI-O3) v20151001 software for nine years (2008–2017) through an extensive inter-comparison and validation exercise using independent observations (satellite, ground-based and ozonesonde). IASI-A and IASI-B Total O3 Columns (TOCs) are generally consistent, with a global mean difference less than 0.3 % for both day- and nighttime measurements, IASI-A being slightly higher than IASI-B. A global difference less than 2.4 % is found for the tropospheric (TROPO) O3 column product (IASI-A being lower than IASI-B), which is partly due to a temporary issue related to IASI-A viewing angle in 2015. Our validation shows that IASI-A and IASI-B TOCs are consistent with GOME-2, Dobson, Brewer and SAOZ retrieved ones, with global mean differences in the range 0.1–2 % depending on the instruments. The IASI-A and ground-based TOC comparison for the period 2008–July 2017 shows good long-term stability (negative trends within 3 % decade−1). The comparison results between IASI-A and IASI-B against smoothed ozonesonde partial O3 columns vary in altitude and latitude, with maximum standard deviation for the 300–150 hPa column (20–40 %) due to strong ozone variability and a priori uncertainty. The worst agreement with the ozonesondes and with UV-vis retrieved TOC [satellite and ground] is found at the southern high latitudes. Compared to ozonesonde data, IASI-A and IASI-B O3 products overestimate the O3 abundance in the stratosphere (up to 20 % for the 150–25 hPa column) and underestimates the O3 abundance in the troposphere (within 10 % for the mid-latitudes and ~ 18 % for the tropics). Based on the period 2011–2016, non-significant drift is found for the northern hemispheric tropospheric columns while a small drift prevails for the period before 2011.

The aim of quality management is to ensure that all parts of the organization work together to improve the processes, products, services and corporate culture to achieve long-term success that comes from customer satisfaction. This article was prepared by the author using the system referring to the literature review. The implementation of integrated quality management in education goes through several processes from the preparation, planning, and implementation of the quality of educational services that are expected by education customers. Meeting the expectations of customer education is a quality management paradigm that must be fulfilled, so that those who drop out of school and unemployment can be minimized in the world of our education.

The dielectric properties of cables, reliability and durability depend on quality of production processes, operating conditions and degradation factors, as well. Expected lifetime of cable systems is more than 20-30 years in general. Their failure free operation and long-term stability of properties has a direct impact on the economic return of the investments. According to our experiences the tests in compliance with valid standards are not adequate to verify real life time during operation.

Total Quality Managemen (TQM) in Educational is an effort to improve the quality of education by making continuous and continuous improvements that are customer oriented by involving all members of the organization.In implementing of Total Quality Management (TQM) will face obstacles, because TQM is something new in education. But these obstacles can be overcome by a high commitment attitude that must be shared by all members of the organization. These commitments are long-term

The current mixed-methods study reports the results of a cross-sectional survey of 205 online daters and uses the Investment Model to examine the antecedents of commitment in online dating and users’ decisions to delete their online dating account(s). We hypothesized that the quality of alternatives, investments, and satisfaction with the online dating relationship would mediate the association between online dating intensity and commitment, which, in turn, would predict the intention to terminate an account. The analyses revealed that online dating intensity was associated with greater commitment and a lower likelihood of account termination. There were also specific indirect effects on commitment through the quality of alternatives, investments, and satisfaction, and on termination through investments. Responses to an open-ended question provided more information about users’ decisions to quit online dating. These results point to ways online dating may facilitate the desire for commitment while potentially undermining the long-term stability of relationships.

Integration of Management Total Quality and Information Technology has become very important for countries, businesses, and companies that hope to survive, including educational institutions. The demand for graduates of quality education institutions is increasingly urgent because of the increasing competition in employment, therefore competition in the labor market will be increasingly severe. Integrated Quality Management (Total Quality Management-TQM) is a system of fundamental values and competence in managing organizations with the aim of improving performance in the long term by paying special attention to achieving customer satisfaction while paying adequate attention to meeting the needs of all organizational stakeholders concerned. Quality problems in TQM require the involvement and responsibility of all parties in the organization. Its application in the world of education has had a positive impact, especially in universities. Where to support the implementation and implementation of TQM in an increasingly advanced world, information technology is needed. Information technology is a variety of facilities consisting of hardware and software to support and improve the quality of information for the community quickly and with quality.
