The article describes the issues of transport of bulk materials. The knowledge of this process has a key impact on the rational planning of transport tasks. It is necessary to have knowledge about the transport services market and the competition that exists in it. In order to achieve a competitive advantage on the market, enterprises should analyze data on the implementation of transport tasks on an ongoing basis. It is also important that the costs incurred from the conducted activity are minimized, while increasing the quality of services and taking into account the sustainable development of the enterprise. The study analyzes data from a few selected motor vehicles in the period of 3 years of operation, coming from an enterprise specializing in the transport of bulk materials. Moreover, a global sensitivity analysis was performed based on a neural model describing the impact of the analyzed factors on the company’s profit. The results show that the most important factors influencing the company’s profit are the fuel consumption of individual vehicles, the driver (driving style) and the month (average temperature, weather conditions).

The article examines the processes, criteria and factors to ensure the quality of passenger transport services. Object of study - processes to ensure the quality of passenger transport services in the context of European integration of Ukraine. Purpose - a study of the world experience in the formation of the concept of quality of transport services, summarizing the main factors that affect the quality of transport services, as well as the main criteria affecting the qualitative characteristics of the services of the transport. Method study - generalization of fundamental works of Ukrainian and foreign scientists of economists is in the internal checking system, dialectical going, fundamental positions of economic theory, system-logical approach near research of the economic phenomena and processes. Satisfaction the needs of society and economy of passenger transport services depends on the quality and timeliness of those services. Questions of quality passenger transport services are interested in users of transport services, companies providing them. However, the requirements and the basic criteria for assessing the quality they are different. If the passenger transport enterprise interested in providing their services with minimal effort and money, the service users in their assessment pay attention not only on the cost of services, but also on transport safety, comfort, delivery time, etc.. The quality of the transport concept of integrated services, which is constantly being developed and improved. Global trends show that the quality of transport services must ensure the needs and expectations of consumers. Accordingly, it is increasing the importance of defining the qualities that affect the quality of service. Given the transient and dynamic nature of modern society and the lifestyle of the main consumers of the services the system factors and quality criteria must be flexible and dynamic to meet the industry's competitiveness on the European market of services. Awareness of the main criteria for assessing the quality of services will help to identify potential strengths and weaknesses. This will help improve not only the quality but also the process of enterprise management, industry, improve customer satisfaction of services received, will increase competitiveness. The results of the article can be inculcated in-process services of enterprises of a transport complex. KEYWORDS: QUALITY, TRANSPORT SERVICE. CRITERIA of QUALITY, TRANSPORT.

The article examines one of the actual problems of the theory and practice of the logistics systems functioning related to the asymmetry of information in the transport services market. Assessing the level of asymmetry in logistics systems is of fundamental importance to increase the competitiveness of relevant systems. New approach formulated herein estimates the logistics systems asymmetry by taking into account information asymmetry about the quality of transport products, as well as information asymmetry about the quality of products within the boundaries of the corresponding supply chain. This approach allows to take into account its potential capabilities and increase functional stability in the process of logistics systems design.

We investigated the impact of preoperative ultrasonography of the forearm circulation on radial artery conduit selection. Preoperative ultrasound of the forearm circulation was performed routinely in 536 patients planned for radial artery harvesting. The safety assessment of the harvest included the following algorithm of tests: the ultrasound, the Allen test, and pulse oximetry. The quality criteria that were used to exclude a radial artery from harvesting were small size of the artery, diffuse atherosclerosis, calcifications, and severe neointimal hyperplasia. The overall rejection rate due to safety reasons was 16.4%. Seventy-one (13.2%) radial arteries did not fulfill the conduit quality criteria and consequently these arteries were not harvested. In 13.4% of radial arteries, localized arterial wall disease was found in the distal third of the artery. The distal part of the artery was discarded and the rest was used as a conduit. Our results indicate that the ultrasound provides an accurate preoperative insight into the radial artery morphology, enabling selection of the arteries with favorable morphological features.

Explanations about the surrounding world are of particular significance for children since it is a way for them to learn and cognise the environment. However, Legare (2014) maintains that little is known about the impact of explanations on learning. For the past decade, explanations have been one of the major themes in the studies of cognitive psychology. They aim at answering the key questions: what is the nature of the phenomenon (explanation), what is it composed of, what are its quality criteria, how is it constructed and perceived by children (Lombrozo, 2006). Hence, the aim of the current paper is to explore the ability of pre-school and primary school children to assess the quality of explanations. The aforesaid aim was posed in accordance with the methodology developed by the authors (the methodology was designed with reference to the study of Baum, Danovitch, and Keil (Baum et al., 2008). The research involved 61 children: 20 pre-school children, and 41 primary school children (21 children of the second grade, and 20 children of the fourth grade respectively). The main conclusions of this research are: – children’s ability to assess the quality of explanations increases from pre-school age to the second grade of primary school, yet at this period, it remains unchanged (from the second to fourth grade); – despite that the ability to assess the quality of explanations on familiar and unfamiliar topics differs in both age groups (pre-school and primary school), the differences are not statistically significant. It has been determined that, assessing explanation on familiar and unfamiliar topics, pre-school children and fourth grade pupils are able to distinguish circular explanations on familiar topics in a more similar way than assessing explanations on unfamiliar topics. Moreover, older primary learners are more precise in assessing explanations on familiar rather than unfamiliar topics; – the oldest children (fourth grade learners) choose a noncircular explanation as a better one more knowingly and reasonably. Meanwhile, children of pre-school age and second grade pupils cannot often point out why they have chosen a noncircular explanation; – only older children (mostly fourth grade pupils and several second grade learners) are able to recognise and identify the structure of a circular explanation. The conducted research provides insights into the ability of small children to assess the acquired information. It is noteworthy that the assessment and creation of explanations is one of the mechanisms of learning and development (Bonawitz et al., 2008; Legare, & Lombrozo, 2014). Hence, their impact is obvious: explanations give a basis for learning, whereas prior knowledge is fundamental for explanations (Williams, & Lombrozo, 2013).

Recent years have seen a dynamic growth of ecommerce. This links to technological developments, an increase in the number of people who have access to and actively use the Internet, and the use of mobile devices. The aim of the paper is to present the results of a questionnaire survey of the factors behind the development of e-commerce services. Besides, the paper defines the interdependence between the frequency of internet shopping and the logistic aspects of e-commerce. A hierarchy is also established of the degree of satisfaction as regards the quality criteria of e-commerce services. The analysis covers data from a questionnaire survey of 100 customers using ecommerce in Poland. The respondents were customers using e-commerce services aged between 20 and 24. The questionnaire was based on a five-point Likert-type scale of between 1 and 5. The survey was qualitative and nationwide. The analysis was done using the Statistica 10 software. The Pearson correlation was chosen from amongst the methods available to determine the impact between the surveyed variables. Firms that provide e-commerce services aim to fulfil the ever increasing needs and expectations of their customers. They attach a lot of importance to the quality of customer service which is demonstrated by the high scores awarded by the respondents.

When a new product is designed in an industrial context, it must be possible to produce this product with the desired level of quality and at an acceptable cost for the market. One of the important quality criteria is compliance with functional tolerances. To evaluate the impact of manufacturing defects on the quality of parts produced, designers simulate the influence of the error stack-up in different machining operations to check compliance with functional tolerances. This paper builds on the model of manufactured part and the Jacobian–Torsor model and presents a combined approach for analyzing machined part tolerance taking into account the geometrical defects occurring in a multistage machining process (positioning defects and machining defects). This combined approach aims to help designers when evaluating the different process plans by predicting the worst quality of finished parts. This study uses interval arithmetic because it offers the advantage of expressing uncertainties and deviations.

Measuring the impact of orthognathic surgery on quality of life is of significant importance in patients with cleft deformities. Standardized tools such as patient-reported outcome measures (PROMs) are needed to fully comprehend patients’ needs and perceptions. Therefore, the availability of reliable, valid, and comprehensive questionnaires for patients is essential. The aim of this study is to identify PROMs measuring the impact of orthognathic surgery on quality of life in patients with cleft deformities and to evaluate the identified PROMs. A systematic search of the literature was performed according to the preferred reporting items for systematic reviews and meta-analysis guidelines. All validated PROMs, regarding the impact of orthognathic surgery on quality of life in patients with cleft deformities, were identified and assessed according to the quality criteria proposed for measurement properties of health status questionnaires. An electronic search yielded 577 articles. After a full-text review of 87 articles, 4 articles met the inclusion criteria, comprising 58 PROMs. Of these 58 PROMs, 1 PROM (the CLEFT-Q) has been validated to measure the impact of orthognathic surgery on patients with a facial cleft. Evaluation of methodological quality of the included articles and assessment of the measurement properties of the CLEFT-Q show that the CLEFT-Q scores relatively good for all available measurement properties, making it suitable for immediate use. The CLEFT-Q was found to be the only valid instrument so far to measure the impact of orthognathic surgery on the quality of life in patients with cleft deformities.

The world is recently moving towards quality criteria in every field. For this Accreditation process has been introduced in every Discipline, Institute and Program to maintain the standards of quality. Accreditation refers to the authenticity and fairness in achieving the benchmarks of standards of program, a course, a module or an Institution. (Harvey, 2004). Accreditation provides certainty that the course or program will meet the demands and requirements of the quality standards. In order to produce trained professionals’ quality in higher education is required and Accreditation process will provide the Quality Assurance. As the teachers are the roots of every profession, therefore the Accreditation Process is also introduced in the field of teacher Education Program to maintain and improve the quality of Teacher Education Programs. When talking in context of Pakistan, there is always an issue regarding in quality of Education in Pakistan. In order to meet this demand NACTE (National Accreditation Council for Teacher Education) is established so that the quality criteria can be achieved through the process of Accreditation of different Teacher Education Programs in Pakistan. (Shakoor, & Farrukh, 2016). The programs or courses having NACTE Accredited certificate can be accepted globally and thus can serves as a basis of good professional start. The present study aims to find out the comparative analysis of the impacts of NACTE Accredited and Non-Accredited Teacher Education Programs on student's Achievement. The study is conducted on students of B. Ed honors studying in different institutions in Karachi. To carry out comparative analysis MGA (Multigroup Analysis) is carried out on Smart PLS: 3. The analysis done revealed high ‘values of Accredited groups as compared to nonAccredited groups, concluding that there are significant differences in the impact of two types of programs; Accredited and Non-Accredited teacher Education Programs on student teacher`s achievement. The results declared that Accredited Programs
