Abstract A dose audit of 16 facilities in 11 countries has been performed within the framework of the Forum for Nuclear Cooperation in Asia (FNCA) quality assurance program. The quality of radiation dosimetry varies because of the large variation in radiation therapy among the participating countries. One of the most important aspects of international multicentre clinical trials is uniformity of absolute dose between centres. The National Institute of Radiological Sciences (NIRS) in Japan has conducted a dose audit of participating countries since 2006 by using radiophotoluminescent glass dosimeters (RGDs). RGDs have been successfully applied to a domestic postal dose audit in Japan. The authors used the same audit system to perform a dose audit of the FNCA countries. The average and standard deviation of the relative deviation between the measured and intended dose among 46 beams was 0.4% and 1.5% (k = 1), respectively. This is an excellent level of uniformity for the multicountry data. However, of the 46 beams measured, a single beam exceeded the permitted tolerance level of ±5%. We investigated the cause for this and solved the problem. This event highlights the importance of external audits in radiation therapy.

Inspection Process

A successful quality assurance program in any organization needs good measurement systems. The concept of measurement system refers to the manpower, machines, materials, methods and mother nature involved in obtaining measurements. Measurement system analysis (MSA) is a set of procedures which are used to determine the amount of variation due to the measurement system and if the measurement data are valid. Most problematic measurement system issues come when the results of a measurement system are qualitative values such as “pass” or “fail” (attribute data) rather than quantitative values (variable data). Because in industry many measurement systems deal with qualitative data, the assessment of the visual inspection process is a contemporary approach for quality assurance in most manufacturing organizations. The aim of this paper is to apply the MSA attribute study in a local company from the Sibiu region supplying products for automotive industry, to ensure the quality of the visual inspection process for one of their parts, respectively the exterior lighting projectors (Day Running Light, DRLs). The output data were analyzed using Minitab software. The conclusion was that the visual inspection process must be improved by appraisers training and developing panel with samples for the most common defect types of DRLs.

Intended Use

Quality does not mean compliance with a checklist of standards but rather “fitness for use.” Compliance with a checklist of standards will only assure quality if the standards specifically address the intended use of the final results. In the design of a quality assurance program, the emphasis is upon quality controls and monitoring schedules for those aspects of the study that significantly alter the variability of the final results and alter the variability to the extent that the final results are no longer useful. Therefore, the principal researcher in conjunction with the quality assurance staff contribute to the quality of a study by applying combined expertise in the design of specific reference standards that both address the fitness for use criterion and the more comprehensive government standards.

We present an overview of key aspects of the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility (ACRF) data quality assurance program. Processes described include instrument deployment and calibration; instrument and facility maintenance; data collection and processing infrastructure; data stream inspection and assessment; problem reporting, review and resolution; data archival, display and distribution; data stream reprocessing; engineering and operations management; and the roles of value-added data processing and targeted field campaigns in specifying data quality and characterizing field measurements. The paper also includes a discussion of recent directions in ACRF data quality assurance. A comprehensive, end-to-end data quality assurance program is essential for producing a high-quality data set from measurements made by automated weather and climate networks. The processes developed during the ARM Program offer a possible framework for use by other instrumentation- and geographically-diverse data collection networks and highlight the myriad aspects that go into producing research-quality data.

Key Concepts

Quality assurance programs have become an integral part of the health delivery processions during the past quarter century. They generally focus on the appropriateness and adequacy of services provided, with the objective of identifying and correcting deficiencies of service. Appropriateness and adequacy are assessed by the degree of adherence of practices to explicit standards, and these in turn relate to criteria of structure, process, outcome and efficiency. The key concepts and methodologies of quality assurance programs are reviewed, and it is suggested that they can be readily applied to Canadian universities. A quality assurance program within a university could be a powerful administrative and curricular development tool that would serve to define and enhance the quality of educational experiences of students.

Model Combining

The aim of this article is to discuss the conceptual connections between virtue, ethics, and quality of care, suggesting that there is a profound connection between virtue and quality. Virtue is discussed as a basic concept in caritative caring ethics, reflecting on the fundamental idea of quality, resulting in a model combining the two of them. This forms a solid basis for any quality assurance program and is, thus, of an abstract, general nature.
