Abstract The aim of this paper is to highlight the fact that there is a significant relationship between design quality and process quality, and then the quality of the finished products (internal quality) and the later use of the products by the consumers (external quality). The paper outlines the model of the synergy between design management and process management. Since design quality is the first link in this chain of creating quality, it is necessary to adequately carry out the design process, or provide high-quality design. High-quality design includes connectivity and collaboration between functions that can contribute to the design process, such as: research and development, production, marketing and supply. In order to achieve this, it is important to continuously work on education and training of employees. In addition, it is necessary to apply the tools characteristic for providing quality design, but also the common tools important for quality management. Accordingly, the subject of the paper is examining the impact of employee training, the implementation of quality management tools and application tools for quality design as a factor in establishing links between business functions that should be included in the design process. Based on the application of tools such as regression analysis, cluster analysis and correlation analysis, the results of empirical research suggest that these factors affect the establishment of links between the observed business functions, and facilitate providing the quality of the design process.

The Impact

Quality of plum jerkum is significantly associated to the profile of volatile compounds. Therefore, we decided to assess the impact of various fermentation types on selected properties of plum jerkums, especially compounds which contribute to the aroma of the finished product. We used the following yeast strains: S. cerevisiae S1, H. uvarum H2, and Ethanol RED (S. cerevisiae). Moreover, we considered spontaneous fermentation. S. cerevisiae and H. uvarum strains were isolated during the fermentation of Čačanska Lepotica or Węgierka Dąbrowicka (plum cultivars), respectively. As for fermentation type, spontaneous fermentation of H. uvarum H2 provided the best results. It could be associated to the fact that plum juices fermented with H. uvarum H2 presented the highest concentration of terpenoids, esters, or some higher alcohols. In the current paper, application of indigenous strains of yeasts resulted in the required oenological characteristics, e.g., highest fermentation efficiency and concentration of ethanol was determined in juices fermented with Ethanol RED (S. cerevisiae) and also with S. cerevisiae S1. Our results suggested that indigenous strains of yeasts present in plums demonstrate great potential for the production of plum jerkums of high quality.

This study aimed to describe the health-related quality of life of elderly women with experience in fall treatment as well as to prepare basic data for the development of interventions to improve the quality of life for this group. The study was based on raw data from the 2019 Korea Community Health Survey. Using the SPSS program, the characteristics of the subjects were tested by frequency, percentage, and chi-square test. To establish the impact of fall experience on the health-related quality of life of elderly women, the OR and 95% CI were calculated using multiple logistic regression analysis. Of the 4260 people surveyed, 44.7% of the elderly women said they had a high quality of life, whereas 55.3% of the elderly women said they had a low quality of life. A younger age was associated with a better-rated health-related quality of life. Those who lived in a city and had a high level of education tended to describe a high quality of life. The quality of life was considered high by those who exercised, but low by those who were obese or diabetic. The results of this study can lead to a better understanding of the experiences of elderly women who have experienced falls, and they can be used as basic data for the development of related health programs.

One of the main concerns in companies is quality management and its relationship to firm performance. Recently a growing interest in research is the important role of the business environment in the competitive strategy choices of companies. By proposing a conceptual framework for a general model that explains the quality management practices-firm performance link and the business environment-firm performance link, we test the moderating role of competitive strategy in the two links empirically. A survey was conducted of 229 pork-processing firms in the emerging economy of China. We find that specific quality management practices contributing to higher performance include in-company quality management, supplier quality management, employee involvement in quality management and process management, while quality design and customer quality management are not included. Findings also indicate that the business environment (government support in our research) has a positive relationship to firm performance. Competitive strategy only strengthens the relationship between firm performance and quality design, process management, supplier quality management and customer quality management.

Web Real-Time Communication (WebRTC) combines a set of standards and technologies to enable high-quality audio, video, and auxiliary data exchange in web browsers and mobile applications. It enables peer-to-peer multimedia sessions over IP networks without the need for additional plugins. The Opus codec, which is deployed as the default audio codec for speech and music streaming in WebRTC, supports a wide range of bitrates. This range of bitrates covers narrowband, wideband, and super-wideband up to fullband bandwidths. Users of IP-based telephony always demand high-quality audio. In addition to users’ expectation, their emotional state, content type, and many other psychological factors; network quality of service; and distortions introduced at the end terminals could determine their quality of experience. To measure the quality experienced by the end user for voice transmission service, the E-model standardized in the ITU-T Rec. G.107 (a narrowband version), ITU-T Rec. G.107.1 (a wideband version), and the most recent ITU-T Rec. G.107.2 extension for the super-wideband E-model can be used. In this work, we present a quality of experience model built on the E-model to measure the impact of coding and packet loss to assess the quality perceived by the end user in WebRTC speech applications. Based on the computed Mean Opinion Score, a real-time adaptive codec parameter switching mechanism is used to switch to the most optimum codec bitrate under the present network conditions. We present the evaluation results to show the effectiveness of the proposed approach when compared with the default codec configuration in WebRTC.

The Impact

Most of the existing studies on the impact of disclosure quality of listed companies on the investment efficiency of enterprises are based on the static level, and the article investigates the evolution of disclosure quality on the investment efficiency of enterprises from the dynamic level by dividing the life cycle of enterprises. Taking the data of Shenzhen civil engineering companies from 2013-2017 as the research sample, it uses multiple regression analysis to empirically test the impact of disclosure quality of listed companies on the investment efficiency of enterprises at different life cycle stages. The results show that when no distinction is made between life cycle stages, high quality disclosure can significantly inhibit the inefficient investment behavior of firms; in the growth and maturity samples, high quality disclosure can significantly inhibit underinvestment and overinvestment; in the recessionary samples, high quality disclosure can significantly inhibit underinvestment and has no significant effect on overinvestment.

The Impact

The long lifecycle, also known as durability and the permanence / invariability in the quality of papers and cardbords for graphic art, are today the basic requirements, imposed by printed art in terms of high quality parameters. These two factors are a manifestation, depending on different internal chemical-composition properties of the paper consistency and external influences of the ambience. Longevity and permanence are perceived as a function of aging and are actually observed at a later point in time. It is important to clarify that they are terms with different contents where „durability” is perceived as the ability of the paper or cardboard to resist the impact of wear during use, and the „permanence” is the possibility of product to remain chemically and physically stable for a long period of time.
