Required Quality

In construction production, the safety of constructing buildings and structures is achieved by ensuring the required quality as a result of systematic construction control based on the implementation of a complex of technical, economic and organizational measures at all stages of the object's life cycle. The article deals with the actual problem of improving the quality of construction products-buildings and structures in conjunction with the activities of construction control bodies. The article presents the advanced foreign and domestic experience of ensuring the quality control at the construction sites, providing for the prevention of the underlying causes of defects and increasing the interest of the contractors directly. On the basis of the analysis of the current situation with quality control at the construction market, ways to improve its efficiency by developing a unified system of technological implementation of relevant requirements for the quality of construction products, determining the rational number and business load of construction control engineers, as well as the active activities of self-regulatory organizations in this area are offered.

The analysis and generalization of theoretical approaches to the formation of the construction quality system, the generalization of the legislative and regulatory framework for quality control in construction. Analysis of the theoretical prerequisites for the formation of quality control of construction revealed that the digital transformation of construction is an integral part of the development of modern society, a prerequisite for changing the system of construction, including control, quality assurance and evaluation of construction processes, works, materials, products and structures. It was found that the quality in construction is directly affected by the following factors: quality and completeness of design documentation; the possibility and obligation to comply with legal requirements; quality of construction processes and works, strict compliance with the requirements of technology and construction organization; quality of construction products and structures; technical ability to provide a given level of quality with the help of machines, mechanisms, means of small mechanization, etc .; the level of qualification of management staff, workers and line ITP. The quality system itself can be presented in the format of a "black box", where the factor will be named at the entrance, and at the exit - buildings and structures that meet a given level of quality throughout the life cycle of the object. It is proposed to consider the construction quality management system in the form of a multicomponent formation and at the same time a dynamic environment, which is constantly changing under the influence of external and internal factors and has a high degree of scholasticism and uncertainty. With the introduction of digital technologies in the organization of construction, including VIM modeling, use of artificial intelligence, cloud services for information storage, quality control tools that can be performed without human intervention, such as drones, robotic elements, surveillance cameras and others, the construction quality assurance system has to change, taking into account the realities of time. Therefore, the system of quality formation in the article is proposed to be considered throughout the life cycle of the object - from pre-project research to liquidation. This will, in contrast to existing approaches, not only combine into a single system all the components of assurance, evaluation and quality control, which are used at the level of all participants in the construction, but also to ensure integrated process management.

The Impact

Measures to reduce the impact of the construction sector on the environment and human health need to be taken at the design stage of the facility and evaluate building materials and products from an ecological and economic aspect. For the research needs, a comparison of floor coverings at the design stage was made to assess their impact during the life cycle. The research uses the life cycle analysis (LCA), a methodology that is the basis for analyzing the impacts during the life cycle of the analyzed construction products. The research covers the life cycle stages from A1 to C4, according to the standard ISO EN 15978: 2011. The software package BEES, the National Institute of Standardization and Technology (NIST), the United States of America is used for the turn. Five types of floor coverings were analyzed, from the aspect of their impact on the environment and human health, but also from the economic point of view. The research has shown that in the design phase, using software packages can be managed with the quality of the environment, and the project design, and hence the quality of the facility. The research also points to the need for a national software package that can analyze construction products and materials. Their application would improve the national construction industry and favored materials that are environmentally and economically acceptable in relation to materials with unfavorable effects on the environment and human health.

This paper addresses human and organization errors (HOE) in the context of quantitative reliability analyses (QRA) that are intended to help improve the quality of offshore structures. A classification of HOE is proposed that addresses individual, organization, equipment/hardware, procedures/software, and environmental considerations. A generic process to address the life-cycle quality characteristics of offshore structures incorporating HOE is discussed. Based on these developments, a probability-based risk analysis is developed that addresses HOE in addition to the structure system aspects. Alternatives for improved management of HOE are discussed including quality assurance and quality control (QA/QC), and design of error-tolerant or “robust” structures. Application of the HOE classification, generic assessment process, QRA formulation, and QA/QC measures are illustrated.

The paper deals with the scientific and methodological approach to quality control of the industrial enterprise development at the strategic level based on adapting the control system to the life cycle stages of the organizational structure and products of the industrial enterprise, through which the transition between the stages of the life cycle and the quality of the enterprises’ development in a strategic term can be detected. In terms of the products’ life cycle, the task of control at the strategic level is to detect promptly the stage when the products no longer meet the needs of the market, and to control the transition efficiency from stage to stage. To solve this task, it is proposed to use the following indicators: the dynamics of sales volumes; the dynamics of the products’ market share; the coefficient of products’ competitiveness; the dynamics of products’ profitability; the coefficient of product expectation on the market, etc.

Summary Background: A clinical registry encompasses a selective set of rigorously collected and stored clinical data focused on a specific condition. Hyponatremia has multiple, complex underlying causes and is one of the most frequent laboratory abnormalities. No systematic registries of hyponatremic patients have been reported in the medical literature. The purpose of this project was to create a registry for hyponatremia in order to obtain epidemiological data that will help to better understand this condition. Objective: This paper describes the creation of a registry for hyponatremia within a single institution that employs industry-based approaches for quality management to optimize data accuracy and completeness. Methods: A prospective registry of incident hyponatremia cases was created for this study. A formalized statistically based quality control methodology was developed and implemented to analyze and monitor all the process indicators that were developed to ensure data quality. Results: Between December 2006 and April 2009, 2443 episodes of hyponatremia were included. Six process indicators that reflect the integrity of the system were evaluated monthly, looking for variation that would suggest systematic problems. The graphical representation of the process measures through control charts allowed us to identify and subsequently address problems with maintaining the registry. Conclusion: In this project we have created a novel hyponatremia registry. To ensure the quality of the data in this registry we have implemented a quality control methodology based on industrial principles that allows us to monitor the performance of the registry over time through process indicators in order to detect systematic problems. We postulate that this approach could be reproduced for other registries.

Introduction. The inevitable of post-registration variations due to the improvement of production processes and quality control related to the integration of the modern technological solutions, replacement of equipment, suppliers of raw, consumables and packaging materials, improvement of form release or composition, administrative changes, as well as obtaining new data on clinical efficacy and safety of immunobiological medicinal products (IMP) during post-marketing studies.Text. The purpose of this work is to analyze the post-registration changes in the life cycle of IMP «Сholera bivalent chemical Vaccine» produced by Russian State anti-plague Research Institute «Microbe», reflecting the harmonization of the documents of the registration dossier with the innovations of the Russian legislation, the optimization of production and quality control. First of all, the changes made to the registration documentation for IMP concerned the updating of the dossier in accordance with the adopted Federal laws and Resolutions of the government of the Russian Federation. The following changes related to the optimization of methods for controlling the limit content of impurities of substances used at different stages of antigen production. Also, the changes were associated with the improvement of consumer properties of the drug, namely the introduction of modern polymer packaging and several drug’s form release, convenient for use in practical health care institutions. The latest change of Pharmacopoeia enterprise article (PEA) R N001465/01-111119 regulates the application of identification means in the form of a two-dimensional bar code (QR-code) on the packaging of medicines, which is due to compliance with the requirements of article 67 «Information on medicines. The system of monitoring the movement of medicines» Federal law N 61 «Оn medicines circulation».Conclusion. Maintaining the required level of quality of IMP when changing production technology or control requires a comprehensive analysis of the proposed changes in order to make them in the documents of the registration dossier. At the same time harmonization of documents of the registration dossier with novelties of the Russian legislation is a necessary condition for implementation of production activity within the legal field.

We developed and implemented an annual online survey to administer to residents exiting residency training in order to (1) assess the quality of the residency experience and (2) identify areas of strength and areas requiring improvement. Long-term goals include program planning, policy-making and maintenance of quality control. Survey content was developed from an environmental scan, pre-existing survey instruments, examination of training criteria established by the CFPC and the CanMEDS criteria established by the RCPSC. The survey included evaluation benchmarks and satisfaction ratings of program director and faculty, preparation for certification and practice, quality of life, quality of education, and work environment. The response rate was 28%. Seventy-five percent of respondents were exiting from Royal College training programs. Results of descriptive statistics determined that the overall educational experience was rated highly, with 98.9% of respondents satisfied or very satisfied with their overall patient care experience. Ninety-six percent of respondents were satisfied or very satisfied with the overall quality of teaching. Preparation for practice was identified as needing improvement, with 26% and 34% of respondents giving an unsatisfactory rating to career guidance and assistance with finding employment, respectively. Although 80% of respondents reported receiving ongoing feedback and 84% discussed their evaluations with their supervisors, only 38% of evaluations were completed by the end of the rotation. The results indicate that residents are generally satisfied with their experiences during residency training, especially with their overall educational experience. Areas of improvement include preparation for practice and timeliness of evaluations. Further iterations of this survey are needed to refine the instrument, identify data trends and maintain quality control in residency training programs. Frank JR (ed.).
