AbstractThis paper introduces for the first time the equal intercept transformation radar chart—an improved form—to the assessment of soil environmental quality of Nanling commodity grain base. The equal intercept transformation radar chart, a visual graphical data analysis method, translates data from a numerical to graphical format. This visualization enables data presentation, analysis process and results stick out a mile and is capable of fully retaining information contained in data and excavating it in depth from geometry. Moreover, it overcomes pertinently the main defect of the conventional radar chart that the evaluation result depends heavily on the order of arrangement of indicators. The results indicated that the soil environmental quality at depths of 0–60 cm in the low mountain area of the Nanling commodity grain base was the second grade, while that in the hilly and plain areas were both first grade. The indicators of poor soil environmental quality in the low mountain area were exogenous Cd and endogenous As; those in the hilly area were exogenous Cd and endogenous As and Hg; and that in the plain area was exogenous Cd. The results were in line with the actual situation of the study area.

Изучено влияние технологических приемов на качество муки. Определяли качество зерна озимой мягкой пшеницы Краснодарская 57 по ГОСТ 93532016. При определенной технологической схеме 78м двухсортном выходе муки было получено 70 муки 1го сорта и 8 муки 2го сорта. Качество муки соответствует ГОСТ Р 521892003. Мука 1го и 2го сортов обладает пресным вкусом, запахом, свойственным пшеничной муке массовая доля влаги 14,7 (1й сорт) и 13,5 (2й сорт). Наличие минеральной примеси, зараженность вредителями не установлены. Содержание металломагнитной примеси 0,041 мг (1й сорт) и 0,048 мг (2й сорт), что соответствует стандарту. Массовая доля золы в пересчете на сухое вещество составила не более 0,69 для муки 1го сорта и 0,70 для муки 2го сорта, белизна у. е. прибора РЗБПЛ 52,4 (1й сорт) и 30,0 (2й сорт). Качество сырой клейковины для муки 1го и 2го сортов составляет 70,0 и 78,0 у. е. прибора ИДК1 (I группа) соответственно. Определены также крупность помола остаток на сите 2,0 1,9 и 2,2, число падения 200 и 182 с, массовая доля сырой клейковины 30,3 и 26,6, содержание протеина 13,2 и 12,5 для муки 1го и 2го сорта соответственно. Цвет белый для муки 1го сорта и белый с желтоватым оттенком для муки 2го сорта. По органолептическим и физикохимическим показателям пшеничные отруби соответствовали ГОСТ 716966. В результате гидротермической обработки зерна с применением холодного кондиционирования и отволаживанием в течение 4 ч выход сырой клейковины вследствие повышения водопоглотительной способности белков увеличился с 25 до 26,6. Одновременно наблюдалось ослабление клейковины, возрастание ее растяжимости. При отволаживании зерна в течение 6 и 8 ч происходило некоторое увеличение выхода сырой клейковины, : 27,9 и 30,3 соответственно. Качество клейковины составило 70 у. е. прибора ИДК1, что соответствует I группе качества. Выход муки при 4часовом отволаживании составил 64, при 6часовом увеличился до 66. Высокий показатель общего выхода муки 78 был установлен при 8часовом отволаживании. Холодное кондиционирование способствовало улучшению мукомольных и хлебопекарных свойств зерна, увеличению выхода сортовой муки при меньших затратах электроэнергии. The influence of technological methods on the quality of flour has been studied. The quality of winter wheat Krasnodarskaya 57 was determined according to GOST 93532016. At a certain technological scheme with a seventyeight percent twograde flour yield was obtained 70 flour 1st grade and 8 flour 2nd grade. The quality of flour corresponds to GOST R 521892003. Flour of the first and second grades has a fresh taste, the smell characteristic of wheat flour, the mass fraction of moisture 14,7 (1st grade) and 13,5 (2nd grade). The presence of mineral impurities, pest contamination has not been established. The content of metallomagnetic impurities was found to be 0,041 mg (1st grade) and 0,048 mg (2nd grade), which corresponds to the standard. Mass fraction of ash in terms of dry matter was no more than 0,69 for first grade flour and 0,70 for flour of the second grade, whiteness conditional units of the device RZBPL 52,4 (1st grade) and 30,0 (2nd grade). The quality of wet gluten for flour of 1st and 2nd grades is 70,0 and 78,0 units of the device IDK1 (I group) respectively. Were also defined the particle size of grinding the residue on the sieve 2,0 1,9 and 2,2, the falling number 200 and 182 seconds, the mass fraction of wet gluten 30,3 and 26,6, protein content 13,2 and 12,5 for flour 1st and 2nd grade, respectively. The color is white for the flour 1st grade and the white with a yellowish tinge for the flour of the 2nd grade. By organoleptic and physicochemical indicators, wheat bran complied with GOST 716966. As a result of hydrothermal grain treatment with the use of cold conditioning and softening for 4 hours, the yield of raw gluten due to an increase in the waterabsorbing ability of proteins increased from 25 to 26,6. At the same time, a weakening of the gluten was observed, an increase in its extensibility. When softening grain for 6 and 8 hours there is some increase in the yield of wet gluten, : of 27,9 and 30,3 respectively. The quality of gluten was 70 units of the device IDK1, which corresponds to the quality group I. The yield of flour with fourhour softening was 64, with sixhour increased to 66. High total yield of flour of 78 was set when the eighthour softening. Cold conditioning contributed to the improvement of the milling and baking properties of grain, increasing the yield of highgrade flour with less power consumption.

To increase the yield and quality of Paeonia ostii barks, the research of economic income under Juglans regia trees in difference cultivation management treatments were explored. Four treatments were designed in this study, removing flower bud (T1), clip deadwood and root tillers (T2), spraying Bordeaux mixture on the leaves (T3) and commonly management (T4, CK). The results showed that the yield of cortex moutan in total, first grade and second grade were significantly higher (p≤0.05) than CK, among these treatments, T3 reached to 102.1g per tree that was the highest grades. In quality part, T1 and T2 were not significant than treatment CK in paeonol contents, but the T3 was the significantly higher (p≤0.05) than CK and reached to 1.82% contents. In economic input, treatments were obvious higher than CK, and the T3 reached to 67780.5 RMB that was 13935.5 RMB higher than CK. The leaves disease might be main negative factor for yield and quality of cortex moutan in Luoyang area, Henan province, so spraying Bordeaux mixture with concentration bluestone: quicklime: water = 1: 2: 200 (w/w) on the leaves from middle May to harvest of Paeonia ostii interval 20 d at every year was the best methods in this study because it had small difficulty management, lower labour intensity and higher benefit results in suitable for application in the cultivation model of intercropping Paeonia suffruticosa under Juglans regia trees.

We introduce an approach that supports researchers and practitioners to determine the quality of first-time user experience (FTUX) and long-term user experience (LTUX), as well as to identify critical issues with these two types of UX. The product we chose to study is a mobile fitness application. Mobile apps tend to have a much shorter service life than most other products; thus, the developers/designers need to pay great attention to both first-time and long-term user experience. This study is based on a multi-method approach. We employed the AttrakDiff questionnaire to assess users’ first impressions of the app, and the UX Curve method to evaluate how users’ experience of the app has changed over time. Besides the quantitative data, which helped to determine the quality of user experience, we also collected qualitative data during two interviews with participants, and focused on the issues that predominantly deteriorated user experience. A four-coordinate plane tool was designed later in the data analysis process that combined the two kinds of user experience data at the same time, which led to a qualitative positioning of the user experience status of a certain product. The model was further successfully adopted in the identification of user experience issues of an online fitness application.

This paper reports a study into different ways of applying a highly effective technology for making yeast-free bread from wheat flour of the highest, first, and second grades by the accelerated method. The dough mechanical loosening technology was used, which makes it possible to reduce the time to prepare the high-quality dough and bake bread. This study has confirmed that the mechanical loosening technique makes it possible to make high-quality yeast-free bread by an accelerated method without fermentation and proving. Such a technique reduces the time of dough preparation by 3 times, improves the rheological properties of the dough, and reduces baking time by 2 times, as well as improves the quality of bread from flour of the highest, first, and second grade. The results showed that the safety indicators of yeast-free bakery products prepared from flour of the highest, first, and second grade meet the norms established by TR TC 021/2011 of the Technical Regulations of the Customs Union "On Food Safety". In terms of microbiological indicators, the results demonstrated that during storage for 5 days QMAFAnM ranged as follows: in yeast-free bakery products from flour of the highest grade ‒ from 1.2·102 to 1.8·102 CFU/g. In the yeast-free bakery products from flour of the first grade ‒ from 1.5·102 to 2.1·102 CFU/g; in the yeast-free bakery products from flour of the second grade ‒ from 1.9·102 to 3.2·102 CFU/g. In addition, bacteria of the E. coli group were found on all yeast-free bakery products. Thus, applying the highly effective technology of the accelerated dough preparation could significantly improve the quality of bread, reduce the time of baking, and reliably ensure that useful properties are maintained

The purpose of the study, which we started in October 2018 with the support of the Ministry of Education and Science of Ukraine and the intergovernmental Ukrainian-Finnish project “Learning together”, is to analyze the quality of modern textbooks for the first grade of the New Ukrainian School, to identify outdated scientific paradigms, to identify and systematize cultural problems of textbook publication, which should be taken into account during the editorial and publishing of textbooks for the second and third grades. Methodology. At the initial stage of the study, a bibliographic method was used for the identification and systematization of scientific sources, normative legal documents on the problems of textbook creation. The use of methods of discourse analysis, logical, semantic, context analysis of text and visual components of textbooks for the first grade of the New Ukrainian School made it possible to identify the problematic aspects of the textbook publication culture. Typical flaws in the culture of textbook publication for the New Ukrainian School are systematized using methods of scientific generalization and classification. The results of the research showed a number of problems: visualization of outdated Soviet discourse, systematic errors, consistency and logic of presentation of the material, fairly low linguistic culture of publications, and sometimes unsatisfactory quality of artistic design. The solution of these problems requires a complex, systemic and integrative approaches. This includes the training of editors, publishers, authors, the formation of their high social responsibility, the creation of a single scientific and informational space for authors, reviewers and editors based on the leading publishing houses and academic departments of publishing and editing, the organization of seminars, trainings, summer/winter schools, etc. Such work has already begun within the preparatory stage of the international project “Finnish support for a New Ukrainian School”. The results of the research were used during the All-Ukrainian scientific and practical seminar “New textbook for the New Ukrainian School: Requirements, criteria for evaluation, registration” organized by the Institute for the modernization of the content of education for publishers who worked on textbooks for the second grade of the New Ukrainian School (November 22, 2018), training for experts who assessed the textbook for the second grade of the New Ukrainian School (January 21-23, 2019) and training sessions for publishers of textbooks for the New Ukrainian School (March 12-15, 2019), prepared by using experts from the Ukrainian- Finnish project “Learning together.”

Purpose The shortage of doctor of philosophy (PhD)–level applicants to fill academic and research positions in communication sciences and disorders (CSD) programs calls for a detailed examination of current CSD PhD educational practices and the generation of creative solutions. The intended purposes of the article are to encourage CSD faculty to examine their own PhD program practices and consider the perspectives of recent CSD PhD graduates in determining the need for possible modifications. Method The article describes the results of a survey of 240 CSD PhD graduates and their perceptions of the challenges and facilitators to completing a PhD degree; the quality of their preparation in research, teaching, and job readiness; and ways to improve PhD education. Results Two primary themes emerged from the data highlighting the need for “matchmaking.” The first time point of needed matchmaking is prior to entry among students, mentors, and expectations as well as between aspects of the program that can lead to students' success and graduation. The second important matchmaking need is between the actual PhD preparation and the realities of the graduates' career expectations, and those placed on graduates by their employers. Conclusions Within both themes, graduate's perspectives and suggestions to help guide future doctoral preparation are highlighted. The graduates' recommendations could be used by CSD PhD program faculty to enhance the quality of their program and the likelihood of student success and completion.
