Various studies on the issues regarding economic and environmental sustainability in inventory management have been investigated by many researchers in recent years. However, the integration of ergonomics as an aspect of social sustainability in an inventory model is still scarce. This paper presents an extension of ergonomic inventory modeling with a new mathematical model which integrates relaxation allowance and endurance time to the ergonomic inventory model. The rest allowance is determined by endurance time, contraction time, and relative force based on several items such as weight, and it helps to prevent ergonomic risks and fatigue of the back muscles. The model has been analyzed in a numerical work based on our specific simulator and parameteric analysis to present validness in different scenarios. Consequently, our results show that optimization with ergonomics in production line material supply provides notable advantages as it increases overall productivity.

Известный немецкий теоретик музыки XVII века Вольфганг Каспар Принц в труде „Historische Beschreibung der edelen Sing- und Kling-Kunst“ («Историческое описание благородного искусства вокальной и инструментальной музыки», 1690) назвал Генриха Шютца, Иоганна Германа Шейна и Самуэля Шейдта тремя лучшими композиторами их времени в Германии. Композиторское письмо двух из упомянутых Принцем персон, Шейна и Шейдта, остается малоизученным в отечественном музыкознании. В статье рассматривается малая имитационная форма в хоральных концертах Шейдта из собрания „Geistliche Concerte“ («Духовные концерты»), четыре части которого были опубликованы в 1631, 1634, 1635 и 1640 годах. Тридцатилетняя война (1618–1648), непосредственно коснувшаяся Шейдта, стала причиной обращения композитора к разновидности вокального духовного концерта для небольшого состава, включающего несколько вокальных голосов (в концертах Шейдта это, как правило, три партии) и бассо континуо. Исследуются тексто-музыкальные единицы, образующиеся на основе строки или сегмента строки хорала и становящиеся материалом для имитации, раскрываются особенности имитационной техники, выявляется связь свободной части малой имитационной формы с типом обработки — Cantionalsatz, типологизируются структуры, различающиеся порядком поступления материала строки в малую имитационную форму. В конце статьи прослеживаются изменения, которые претерпевает малая имитационная форма в хоральных концертах по сравнению с хоральными мотетами из первого собрания вокальной музыки Шейдта “Cantiones sacrae” («Священные песнопения», 1620). The famous German music theorist of the 17th century, Wolfgang Caspar Printz, in his work „Historische Beschreibung der edelen Sing- und Kling-Kunst“ (“Historical Description of the Noble Art of Vocal and Instrumental Music”, 1690) named Heinrich Schütz, Johann Hermann Schein and Samuel Scheidt as the three best composers of their time in Germany, the compositional technique of two of them, Schein and Scheidt, remaining poorly studied in Russian musicology. The article examines the small imitation form in Scheidt’s chorale concertos from the „Geistliche Concerte“ (“Sacred Concertos”) collection, four parts of which were published in 1631, 1634, 1635 and 1640. The Thirty Years’ War (1618–1648), which directly affected Scheidt, caused the composer to turn to a kind of vocal sacred concerto for a small cast, including few voices (in Scheidt’s concertos, these are, as a rule, three parts) and basso continuo in the organ. The textual-and-musical units that are formed on the basis of a chorale line or a segment of a line and become the material for imitation are investigated; the features of the imitation technique are revealed; a connection of the free part with the type of arrangement — Cantionalsatz, is established, mapping the structures that differ in the order in which the line material arrives in the small imitation form. At the end of the article, the changes are traced that the small imitation form has undergone in chorale concertos in comparison with chorale motets from Scheidt’s first collection of vocal music “Cantiones sacrae” (“Sacred chants”, 1620).

One of the external obstacles of students is the learning media used by teachers. Learning achievement will be more developed if students actively participate in learning activities. This study aims to improve mathematics learning achievement at line material. The methodology used in this study is an experimental research methodology. The subjects of this study were 7th class students of SMP Negeri 2 Limpung with class VII A as the experimental group and class VII B as the control group. The results showed that the mathematics learning model assisted by Geogebra at  line material is effective to be used, this was seen from the completeness of learning outcomes, the influence of reasoning and communication skills to learning achievement with a regression equation = 36,203 + 0,591x  and a coefficient of determination is 68.7%. Mathematical learning strategies by Geogebra are also better than learning mathematics without Geogebra. Thus Geogebra-assisted learning on line material can be used as an alternative method of learning in order to add the variety of teaching methods in an effort to train students' reasoning and communication skills and increase student learning outcomes..

This research is a Classroom Action Research (CAR) which is the main problem of the low level of mathematics learning outcomes of class III students of MI Datok Sulaiman Palopo City. The research subjects were MI Datok Sulaiman third grade students in the odd semester of 2018/2019 school year with 28 students. This study was carried out in two cycles with number line material. Data collection techniques used consist of tests, observations, and documentation. Data processing and analysis techniques used are quantitative data analysis and qualitative analysis. The results showed that the learning outcomes with the number line material obtained by the average learning outcomes of students in cycle I was 64.85 including the category of not achieving the KKM score (Minimum Completeness Criteria) with the number of students completing learning were 11 people with a percentage of 39%, and learning outcomes in the second cycle on average obtained 82.89 including very good category with the number of students completing 26 with a percentage of 93%. This research was declared successful with the use of concrete media to improve mathematics learning outcomes.

This article will be consider the main areas of cooperation between Soviet departments and religious organizations in international politics from the mid-1950s to the mid-1980s. Contacts of the representatives of the churches of the USSR steadily expanded in geographical and religious terms at that time. The article shows that the establishment of contacts under the religious line, material support and promotion of international relations of religious organizations of the USSR were part of “people’s democracy”. This was used as “soft power” to spread the Soviet ideological project. Religious diplomacy contributed to the reduction of international tension, was a channel of alternative relations between the two opposing superpowers in a bipolar world. At the same time, the Soviet Union continued the ideological struggle against religion and its institutions, and the socially significant activities of Soviet religious leaders were addressed only to foreign audiences.
