Thread quality control is becoming a widespread necessity in manufacturing to guarantee the geometry of the resulting screws on the workpiece due to the high industrial costs. Besides, the industrial inspection is manual provoking high rates of manufacturing delays. Therefore, the aim of this paper consists of developing a statistical quality control approach acquiring the data (torque signal) coming from the spindle drive for assessing thread quality using different coatings. The system shows a red light when the tap wear is critical before machining in unacceptable screw threads. Therefore, the application could reduce these high industrial costs because it can work self-governance. ; This research was funded by the vice‐counseling of technology, innovation and competitiveness of the Basque Government grant agreements IT‐2005/00201, ZL‐2019/00720 (HARDCRAFT project) and KK‐2019/00004 (PROCODA project).

In order to improve confidence in auditor's report and to reduce an audit expectation gap, it is necessary to ensure an appropriate level of transparency in the audit firms. Greater transparency has a positive impact on clients and third-parties trust in audit's functionality, thus enabling the stakeholders to assess the quality of audit services. Audit firms transparency reports, that contain information about their quality control system, governance structure, annual income, clients of public interest and other mandatory factors to disclose information, can be used as a tool to increase the transparency of audit business. This article examines a problem of transparency in Lithuanian audit market. The main objective here was to investigate whether the audit firms provide sufficient transparency of their audit quality control system in annual transparency reports. This objective was achieved by evaluating whether the transparency reports contain elements disclosing firm's quality control system, description of its politics, procedures and techniques in use. Also, whether the reports are individualized, supported not only by the text of 1th International standard on quality control, and do they provide a clear understanding how an audit quality is achieved and sustained. The author uses qualitative research methods: content analysis, comparison, logical and practical experience analysis. During the study, 19 transparency reports of different audit firms (for the financial year from 2009 to 2013) were analysed and the results show that audit firms do not provide sufficient transparency level of their quality control system. In accordance with set evaluation criteria, only a half of the analysed firms had provided sufficient information that was necessary to understand firm's quality control system and how a quality of audit is achieved. However, the Big 4 of audit firms in Lithuania could be distinguished as providing the most comprehensive and transparent reports. On the contrary, the smaller local audit firms have an issue of vague and incomplete reports, which scarcely contribute to a more effective assessment of a service quality that the audit firms provide. This shows that a major part of the analysed audit firms do not perceive transparency problem as an important issue and do not try to increase the confidence level in their service by making audit practice more transparent.

This article examines the comparability of nursing homes and home health care with respect to the quality-control effects of private litigation and state licensure. It explains that the false assumption of broad comparability between nursing homes and home health care could hamper effective regulation of quality in the delivery of home health care. This article has two main sections, the first of which compares nursing homes and home health care in the context of private litigation. Points of comparison in the litigation context include the barriers to private litigation in long-term care, issues in institutional liability, applicable standards of care, and the availability of statutory private rights of action for violations of state licensure standards. Limitations and obstacles in private litigation, particularly potent for elderly individuals, reveal that although private litigation exerts influence on quality control, it cannot replace government regulation. The second main section makes the nursing home and home health care comparison with respect to state licensure and enforcement mechanisms. It begins by identifying a regulatory model focused on the individual caregiver as best-suited for home health care, using governmental regulation of hospitals and nursing homes as alternative models. Next, it provides an overview of the status of licensures for home health care providers, coverage of state statutes, intermediate sanctions currently available, and the experience of several states in the licensure of home health agencies. Finally, it analyzes the rationale for supporting intermediate sanctions for nursing homes and considers the applicability of such sanctions to home health care. Recognizing that regulatory programs alone do not guarantee quality of care, the article concludes with recommendations for how to best utilize private litigation and state licensure mechanisms to achieve effective quality-control regulation.
AbstractThis paper is a study of quality control systems with flexible adaptivity in the presence of new kinds of uncertainty, due to the changes of the environment as well as a higher aspiration of systems performance. The uncertainties lead both to the diversity of quality and engineering information and to that of quality control activities, and the essential problems there are how to manipulate diversified information and how to coordinate diversified activities. In this paper we introduce the concept of common items of information in order to manipulate diversified quality and engineering information and propose a coordination system which integrates diversified quality control activities. We also present a successful application of the coordination system to a company in heavy industry.
Includes bibliographical references (pages 165-169). ; Classical Statistical Process Control Charts are essential in Statistical Control exercises and thus constantly obtained attention for quality improvements. However, the establishment of control charts requires large-sample data (say, no less than I 000 data points). On the other hand, we notice that the small-sample based Grey System Theory Approach is well-established and applied in many areas: social, economic, industrial, military and scientific research fields. In this research, the short time trend curve in terms of GM( I, I) model will be merged into Shewhart and CU SUM two-sided version control charts and establish Grey Predictive Shewhart Control chart and Grey Predictive CUSUM control chart. On the other hand the GM(2, I) model is briefly checked its of how accurate it could be as compared to GM( I, 1) model in control charts. Industrial process data collected from TBF Packaging Machine Company in Taiwan was analyzed in terms of these new developments as an illustrative example for grey quality control charts.
The use of Total Quality Management (TQM) in a company or organization is one of the actions taken by a company or organization to achieve customer satisfaction. This is usually done by the company by adding quality to the internal company. If the internal can be well, it is expected that the external will also be good. In its aim Total Quality Management (TQM) has a long term, Total Quality Management (TQM) focuses on quality, based on the participation of all its members. Total Quality Management (TQM) uses effective strategies, data and communication to integrate quality discipline into the culture and activities of the company. The basic philosophy of Total Quality Management (TQM) is as an effect of customer satisfaction, a company or organization can experience success. Total Quality Management (TQM) can be widely used in manufacturing, education, government and service industries. So Total Quality Management (TQM) is used by companies to improve internal company in customer satisfaction.
Digital technology for quality control of field demulsifiers based on a numerical algorithm for processing digitized Raman spectra (RS) and infrared (IR) spectra was developed and tested. The width of the acceptance limit of the numerical criterion for deciding on the proper quality of demulsifiers for various values of the specific risk of making a false negative decision was calculated. IR and Raman spectra of active substances (Laprols, Neonols, Amines) used for the production of commercial demulsifiers have been registered. Spectral zones and characteristic lines of absorption (IR spectra) and emission (Raman spectra) specific for Laprols, Neonols, Amines have been determined. Using the characteristic spectral bands of the active ingredients, the compositions of demulsifier samples from different batches were compared.
