Common Defect

The article presents the results of an estimation of defectiveness level of sour-milk production (on an example kefir), developed on one of dairy factories of region. To assess the level of defect, statistical methods of control are used - a checklist for the registration of defective products, a control p-chart and Ishikava diagram. The initial data were obtained at the stage of quality control of finished product and entered in the developed form of the control sheet for product defects. The most common defect in the production is established - the leakage of the package, which can be assessed visually, and not with the help of measuring instruments. For evaluation and subsequent analysis of the reasons for the appearance of the established defect, a control p-chart was used on an alternative basis, which makes it possible to control the quality of manufactured products by the number of defective products. As a result of the analysis of the obtained data, it was established that the technological process, from the point of view of statistical forecasting, is acceptable, but this does not mean a high production stability and does not exclude the appearance of defective products. The analysis of the main reasons for the emergence of unsealed packaging products, among them the qualification of personnel, the quality of the used materials and the conditions for their storage, the production environment, compliance with production technology, and others. A subsequent study of the impact of each of these factors will prevent the appearance of defective products and ensure the production of consistently high quality products.

The Impact

The task of improving the quality of agricultural tools by improving the technological processes of their functioning, taking into account the kinematic features of the combined impact of working elements of tools on the soil environment is important from a scientific and technical point of view. To form the required structure and density of the soil layer at the depth of sowing, a hammer perforated tillage roller (HPTR) has been developed. The study aim is to improve the quality of post-sowing compaction and structuring of the soil layer in the seed location zone based on the development of an innovative design of HPTR that combines different effects on the treated environment. The object of research is the kinematic mode of operation of the HPTR, equipped with cylindrical hammers installed at the ends of the rod, which, in turn, are radially and pivotally installed on the axis of the gunFeature of offered HPTR is the excitation of hammer vibrations, which changes the kinematic parameters of the tillage tool as a whole. Lagrange equations of the second kind are used to describe the process of HPTR operation, which is represented as a system of material objects with several degrees of freedom. The conducted studies revealed the periodic nature of changes in the strength of the impact of HPTR on the soil. The obtained equations allow us to determine the features of the HPTR movement at different masses of a hollow perforated cylinder and cylindrical hammers. This is of great importance for increasing the efficiency of soil bolster destruction and creating the soil structure recommended for winter crops sown in the Middle Volga region.

The Impact

The chapter explores a methodological approach where creativity is encouraged through the production of multimodal iPad-mediated narrative texts in the English as a foreign language classroom (EFL) in secondary education. The study, which is based on creativity of human language, evaluates the multimodal productions of a group of students of secondary education (Year 7) in Spain, who work with iPads (1:1 context) within a cooperative learning approach, and analyzes this learning experience from the students' point of view. The results show the impact multimodality has on the own students and on their way of working with the foreign language. The quality of their productions, not only regarding language but also as an act of creation, and the way they appropriate the different semiotic modes multimodality offers will also be examined. Finally, the authors suggest some guidelines to encourage multimodal production and creativity in the EFL secondary classroom and show examples which would help teachers and researchers to develop new didactic proposals at this stage.

The Impact

Purpose: Numerous studies across multiple specialties have evaluated the impact of trial registration on quality of study reports and found significant improvements over several domains. However, the impact of mandatory trial registration on the quality of clinical trial protocols remains hitherto unexplored. Methods: We carried out a retrospective cohort study of clinical trial applications submitted to drug regulatory authority of India for initial review with the objective of comparing methodological characteristics of their protocols. Since trial registration was made mandatory in the country in June 2009, we selected two study periods as between January 2007 to May 2009 (Period I) and July 2009 to December 2011 (Period II). Seventy-five protocols were randomly selected using a computer-generated list for each study period, making a total of 150 protocols. Data on twelve key methodological characteristics were collected including clearly defined primary outcomes, randomization, blinding, use of control group, statistical methods, handling of withdrawals amongst others. Results: More than 3/4th of the trial applications in the two study periods were for new chemical entities and nearly 90% were pharmaceutical industry sponsored studies. Comparing the period before and after implementation of mandatory trial registration, description of clearly defined trial outcomes improved from nearly 42% to 80% (p<0.001), sample size justifications increased from 38% to 70% (p<0.001) and use of allocation concealment improved from 24% to 49% (p=0.001). Marked improvement was also noted for blinding, description of statistical methods and handling of withdrawals and dropouts. Remaining characteristics did not change significantly between the two study periods. The mean cumulative scores for the study protocols improved significantly from 7± 0.296 in the first period to 8.93± 0.346 (p<0.001) in the second period. Conclusions: Our study found a significant improvement in the methodological quality characteristics of the protocols particularly in elements related to minimization of bias and statistical methods, which could be attributed to mandatory trial registration. Overall, the significant improvement was limited to global clinical trials, and room for improvement was noted for two quality characteristics – proportion of randomized studies and trials adequately describing the generation of allocation sequence.

What is the impact of crime on the average individual in this country? What is the impact of the fear of crime on the quality of life in the United States? These questions are addressed in this article not from the point of view of an expert, or of an official in the criminal justice system, or of a victim of crime, but from that of an average person whose experience has included no direct encounter with crime of any kind. Those who have been victims of crime and those affected even indirectly by criminal behavior will react, naturally, with predictable concern; crime also has discernible effects on the attitudes and behavior of people generally, and this impact in turn has a corrosive effect on the quality of life in America.

The Impact

Skin diseases have become one of the most relevant problem due to their global prevalence and intensive growth nowadays. Significantly increased the interest in studying of the life quality of patients with acute and chronic dermatological diseases. The life quality of the patient is the most objective characteristic of the impact of the disease on the patient's condition and various areas of his activity. Emotional or social disorders caused by the disease often do not allow the patient to feel full and healthy person even if clinical recovery. The peculiarities of patients' perception of somatic disease significantly affect both on its course and on the effectiveness of therapeutic measures. Skin diseases form an aspect of life quality that can be dangerous for the prognosis. Dermatological diseases can lead to significant limitations in the physical, emotional and social aspects of patients' lives and can interfere with success in learning and at work, as well as in personal life. In dermatology to assess the quality of life of patients are used: general medical scales, special dermatological scales, dermatological scales for certain nosologies. Purpose — to analyze literary datas on the research methods of life quality in children with dermatological diseases. Conclusions. Determining and evaluating indicators of life quality in patients is a valuable and reliable indicator of the general condition, that allows to monitor the effectiveness of treatment depending on the patient's condition and creates an objective picture of the disease. Assessment of quality of life in patients with dermatological diseases makes it possible to understand the essence of the clinical problem, to determine the most rational method of treatment, as well as to assess its expected results by parameters that are at the intersection between the scientific approach and the patient's point of view. No conflict of interest was declared by the author. Key words: assessment of life quality, dermatological diseases, children.

The materials of the article the analysis of periodic research reports on prospects of feed «Aller Aqua» in the diet of rainbow trout. Overview conceptual experience of increasing the volume of production of this important sector of agricultural production as the breeding and rearing of trout. Trout industry is the most productive direction of the coldwater aquaculture. Costs highly specialized feed for growing trout reach 70% of the total cost of the fish, so the features of feeding, nutritional feed and cultivation technology is relevant and of interest to manufacturers. Today on the Ukrainian market sales volume of feed for trout is a leading foreign firms: Aller Aqua, Biomar, Skretting and others. The quality of the manufactured products of domestic manufacturers often inferior to the requirements of the feed for trout, as domestic production is not always withstand competition. Therefore, at the present rate of trout industry as a promising field of fish farming, and the corresponding demand for feed for valuable fish species such high dependence on imports, now greatly reduces the volume of cold-water aquaculture cultivation sites that accordingly obliges producers special animal feed to improve their quality. The basis of our research is tasked with optimizing normalized using feeding trout feed «Aller Aqua» and results analysis and comparative characteristics of growing trout using Ukrainian feed manufacturers. Purpose is to clarify the nature of the impact of feed «Aller Aqua» and physiological metabolism, growth, development, reproduction and obtaining marketable products rainbow trout that could be the basis for conclusions about the appropriateness and use of feed rules «Aller Aqua», and the possibility of alternative feed means in terms of economy.

Health Care Production

This paper uses the Zon and Muysken (2001) model to investigate the effect of increasing the retirement age on health care production, human capital accumulation, and economic growth. All three sectors are interrelated, since the overall level of health affects both workers and the accumulation of human capital, while a higher level of human capital is related to better quality of health. And, finally, health and human capital affect the output of the economy. From the economic growth point of view the results seem to be positive. Increasing labor availability raises productivity in the health sector, which ultimately improves labor productivity, resulting in increased capital accumulation and economic growth. On the other hand, it is estimated a reduction in the propensity to consume and a smaller portion of the labor force allocated in the health sector.

The Impact

The aim of this study was to determine the impact of oral health on adolescent quality of life and to compare the results obtained using standard statistical methods and artificial intelligence algorithms. In order to measure the impact of oral health on adolescent quality of life, a validated Serbian version of the Oral Impacts on Daily Performance (OIDP) scale was used. The total sample comprised 374 respondents. The obtained results were processed using standard statistical methods and machine learning, i.e., artificial intelligence algorithms—singular value decomposition. OIDP score was dichotomized into two categories depending on whether the respondents had or did not have oral or teeth problems affecting their life quality. Human intuition and machine algorithms came to the same conclusion on how the respondents should be divided. As such, method quality and the need to perform analyses of this type in dentistry studies were demonstrated. Using artificial intelligence algorithms, the respondents can be clustered into characteristic groups that allow the discovery of details not possible with the intuitive division of respondents by gender.
