Сравнение результатов вычисления функции эффективности с использованием выведенного в следствии соотношения и с помощью известного соотношения для нормального распределения ошибок показало, что результаты совпадают. Построены оптимальные планы эксперимента для различных распределений случайных компонент.
The problem of experimental design under conditions of errors in the explanatory variables is considered. The proposition of the method for calculating the Fisher information matrix elements using the Generalized Lambda-distribution is formulated and proved, the consequence of the method for calculating the efficiency function of the experimental design is proved. This method of calculating the Fisher information matrix takes into account the heterogeneity of the errors in random distribution throughout the planning area. In this paper, studies of the synthesis of optimal experimental designs using proven proposition and consequence under various conditions of computational experiments are presented. The results of calculating the efficiency function using the obtained relation and using the known relation for the normal distribution of errors are compared, it is found that the results coincide. Optimal experimental designs are constructed for various distributions of random components. The results of the synthesis of optimal experimental design showed that when function of efficiency is constant throughout the planning area then the optimal experimental design is equilibrium plan. When there are differences in the values of the efficiency function in the planning area, the optimal plan ceases to be equilibrium

The aim of the article is to identify the characteristics and creative potential of customization in modern design activities, through which the needs for individualization of clothing at the request of consumers are widely realized. The methodological basis of the study is an integrated approach. The method of analysis and synthesis allowed the consideration of customized production as the interaction of producer and consumer, which determines the demand and competitiveness of the design product, its artistic and aesthetic value. Methods of visual-analytical and functional analysis of customized design objects provided an opportunity to establish the potential and prospects of mass customization, to justify it in terms of individualization of things as a specific consumer choice, as well as the principle of designing design objects in the learning process. It is established that, according to most scientists, customization is, first of all, individualization of the producer's relationship with the consumer. Prerequisites for its active use in the fashion industry, in particular, in design activities, are long overdue. It was found that by satisfying individual customer requests, using flexible production systems, etc., mass customization allows companies in the fashion industry to get rid of excess stocks of finished products that become obsolete too quickly, and makes it possible to make products more attractive. It is shown that the concept of "smart (savings) consumption", for which the principles of customization are extremely promising, can be successfully implemented in the process of providing educational services. The article highlights the theoretical aspects of the essence of customization as a "mass individualization" of design products. The existing principles of clothing customization are analyzed. Possibilities and types of customization in the activity of modern designers against the background of real market conditions are characterized. The potential of customizing in design in general and in the educational process of training fashion designers in particular is shown. The obtained results provide an opportunity to systematize the types, principles and techniques of customization as an experience of practical implementation of the concepts of "smart consumption", individualization and personification in clothing design.

The purpose of the publication is to analyze the virtual and augmented reality in the work of Ukrainian artists of the last thirty years. The study digital visual art space is the analytical methods to determine internal trends and prospects of contemporary Ukrainian art. The main methodological approach is the cultural-semiotic analysis of the forms of manifestation of visualization of modern art culture. The application of a systematic approach allowed to study semiotic systems that contribute to the comprehensive disclosure of the problem of semantics of modern forms of visualization. The peculiarities of the use of technologies for the support and demonstration of works of art are revealed, the emphasis is on the emergence of new digital trends in contemporary art, thanks to which visual works function in their own media environment. Virtual and digital realities in the fine arts replace the artist's canvas, and the ironer allows him to immerse himself in other unreal worlds of the author's subconscious. Thus, from a simple fascination with technology, the modern generation of artists quickly moved to quality and content requirements, conceptuality and communication between the author, viewer and work of art, which requires artists to understand modern technology, traditional techniques of painting. The scientific novelty of the work is to identify the main characteristics of the development of modern visual arts with the help of virtual space in the Ukrainian cultural environment. The practical significance of the obtained results is that they can be used as a factual and theoretical basis for the creation of relevant sections in scientific and scientific-methodical publications on the history of contemporary Ukrainian art.

Published: August 2021

Lack of water can cause serious health problems. In reality, some people do not know the amount of water they must drink daily. It's hard to find out the daily water intake needs because it is affected by a lot of things and it will be better to involve a nutritionist or health expert to get the best amount, which may require extra cost. To overcome these problems, it is necessary to have a system that is incorporated in an integrated system with the ability to calculate the ideal level of water needs for the body according to factors that affect the level of water needs and able to remind users to keep their daily needs. IoT-based smart water dispensers that can be integrated with android applications and cloud servers into a single system can be used to help solve these problems. The system has a knowledge base obtained from professionals to determine user water consumption. The system calculates the water consumption using the GPPAQ questioner and Estimated Energy Requirement (EER) formula. The base knowledge is implemented on Android applications, and this application can track the amount of water that has been consumed by the user. The test results show that the system can calculate the amount of water demand based on some factors such as the level of physical activity, age, and body weight. The water dispenser system has an accuracy of recording the amount of air released by 92.6%, so there is a difference in the calculation in the Android application to the amount of air that the user takes from the water dispenser

This study aimed to evaluate the reaction of six grapevine rootstocks (MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4, Salt creek) and two cultivars (Quebranta and Torontel) to three species of the root-knot nematode (Meloidogyne incognita, M. arenaria and M.hapla). The experiment was performed as a completely randomized design with an 8 × 3 factorial scheme and six replicates per treatment. The experimental unit in each replicate comprised a grapevine cutting planted in 3 kg bags with sterilized soil. Cuttings were inoculated with 5000 eggs + juveniles (J2) of M. incognita, M. arenaria and M. hapla. Six months after inoculation, plants were removed from the bags, and the reaction was determined by evaluating the number of galls (NG), number of nematodes per gram of root (NNGR), and reproduction factor (RF). The evaluated rootstocks, MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4 and Salt Creek, were resistant to M. incognita, M. arenaria and M. hapla, except for Salt creek, which was susceptible to the latter. The Quebranta and Torontel cultivars were susceptible to the Meloidogyne species under study.

The decentralization of PBB-P2 in Indonesia is expected to produce a better PBB-P2 administration system. One indicator of a better PBB-P2 administration system is a fair collection of PBB-P2 based on tax base (NJOP) valuation close to market prices. This study examines whether NJOP, as the basis for the imposition of PBB-P2, is in accordance with the market price using the assessment ratio. This study found that the current level of accuracy of the NJOP has not met the standard agreed upon by the IAAO. In addition, this study also found that the NJOP accuracy rate in big cities was slightly better than the NJOP accuracy rate in other cities. In addition, this study also found that there was no positive correlation between NJOP updating activities through SPOP filling and NJOP accuracy.
Desentralisasi PBB-P2 di Indonesia diharapkan menghasilkan sistem penatausahaan PBB-P2 yang lebih baik. Salah satu indikator dari sistem penatausahaan PBB-P2 yang lebih baik adalah pemungutan PBB-P2 yang adil dengan dasar pengenaan pajak (NJOP) yang mendekati harga pasar. Studi ini meneliti apakah NJOP sebagai dasar pengenaan PBB-P2 sudah sesuai dengan harga pasar menggunakan assessment ratio. Penelitian ini menemukan bahwa tingkat akurasi NJOP saat ini belum memenuhi standar yang disepakati oleh IAAO. Selain itu, penelitian ini juga menemukan bahwa tingkat akurasi NJOP di kota besar, sedikit lebih baik dibanding tingkaat akurasi NJOP di kota-kota lainnya. Selain itu, penelitian ini juga menemukan bahwa tidak ada korelasi positif antara kegiatan pemutakhiran NJOP melalui pengisian SPOP dengan tingkat akurasi NJOP.

The study used experimental research design to randomly selected senior high school students in analysing their attitude and achievement in statistics when contextual teaching is implemented. In addition to structured questionnaires, semi-structured interviews with the students were also conducted to provide rich descriptions about learning experiences with contextual teaching. Results revealed that students have positive attitude towards statistics and that students learn better with contextualized instruction than direct instruction. With this, contextualized instruction must be promoted in teaching statistics. By linking it to the real world, students would be able to view statistics more than just a subject. Thus, it makes the statistical hypothesis testing learning more enjoyable and exciting.
Diálogo, separación y suspensión: prácticas de manejo de conflictos en escuelas primarias mexicanas
Authors: Perales Franco Cristina 
Published: August 2021

Este artículo tiene como objetivo dar cuenta del análisis de las características de tres prácticas comunes de manejo de conflicto en dos escuelas primarias públicas mexicanas: el diálogo, la separación de actores y la suspensión, así como valorar sus implicaciones para la convivencia escolar respecto a la construcción de paz, la inclusión y la participación. En su componente metodológico, se presenta la investigación etnográfica de la que se deriva este artículo y el análisis temático y situacional desarrollado. Como marco teórico, se muestra una distinción entre aproximaciones restringidas y amplias de convivencia escolar, y se hace hincapié en los procesos de peacekeeping (mantener la paz), peacemaking (hacer la paz) y peacebuilding (construir la paz) en estas aproximaciones. El resultado central revela que la manera en que se desarrolla el diálogo, la separación y la suspensión da cuenta de una visión restringida de convivencia orientada a controlar los comportamientos inadecuados de los estudiantes, la cual es congruente con un manejo de los conflictos enfocados en el peacekeeping, que restringe la inclusión y la participación de los estudiantes y no conforma acciones sostenibles para transformar los conflictos que lleven a la construcción de paz.

Published: August 2021

Sources of fertilizer are one of the major factors influencing baby spinach leaf texture, sweetness, bitterness and after-taste. However, the effects of fertilizer sources on baby spinach growth performance and consumer preferences are not known. A survey was carried out at the Seke Teachers’ College (SKC) community, Zimbabwe to determine the consumer preferences on the baby spinach grown on the organic fertilizer (cattle, poultry and goat manures) as well as on control inorganic fertilizers (7% N, 14% P, 7% K). The study used 32 females and 30 males as panellists for sensory evaluations. Organoleptic tests were performed for the baby spinach leaves using a panel of 62 testers. An interval line scale (16 cm long) was used to measure the liking for sweetness, colour, bitterness and after-taste. A 9-point hedonic scale was used to decide the overall preferences. Organoleptic tests showed significant differences (P<0.05) in appearance and taste between the inorganic and organic fertilizers used. The baby spinach leaves grown on organic fertilizers was preferred more compared to that grown on inorganic fertilizer (control). Therefore, it is recommended to use organic fertilizers in baby spinach production in order to satisfy consumer preferences.
