Nowadays economy has developed very fast, along with the rapid development of science and technology which is increasingly modern makes the competition between companies become more intense. With the intense competition between companies encouraging each company to do a good inventory control in supporting and expediting the production activities. According to Assauri (2008:176) Inventory control is one of the activities of the activities sequence that are closely related to each other in the entire company's production operations in accordance with what has been planned both time, quantity, quality, and cost. In an effort to control inventory one of the methods that can be used is the "Economic Order Quality” (EOQ) analysis. EOQ is the most economical volume or amount of purchases to be made at each time of purchase. In addition to determining EOQ, companies also need to determine the point of order for raw materials to be used or reorder point (ROP) and determine the amount of safety stock. Data sourced from Mie Sinar Sulawesi Cap Dua Angsa Company. It can be seen the results of research conducted show that the difference in quantity and frequency of purchases that are more efficient with a total quantity of 10.910 kg in one order and frequency of 5 orders and reorder point is 2.212 kg while the amount of safety stock is 1.892 kg. By applying the EOQ method, it can make a company able to create economical inventory costs. However, before implementing this method the company must also calculate the important aspects such as capacity, warehouse, capital costs, and the risks of damage that the company must avoid.

Nature of Sense-Reporting in Difference of the Text of Hadith; A Research Study
Authors: Dr. Hafiz Rizwan Abdullah  , Dr. Iftikhar Alam  , Dr. Nisar Ahmad
Published: December 2021

Among different methods of narrating hadith, there is a method which is called Riwayat bil-ma’na (sense-reporting). It means that a narrator narrates a hadith in his own words without uttering the actual words he listened originally from the Prophet (PBUH). The actual rule of narrating hadith was that it was narrated uttering the original wording of the Holy Prophet (PBUH). Whereas it was allowed in utmost circumstances. If some narrator had to make sense-reporting of a Hadith, he needed to use such words which clearly explain that the words being used are not the words of the Holy Prophet (PBUH) but those of the narrator. Sense-reporting was allowed only in specific circumstances. Moreover, only those narrators were allowed to make sense-reporting who had the real sense of the words and their reasoning and were aware of language skills and Sharia, and the sense-reporting of whom would not add or subtract something in hadith and its exact order. In this research article, various kinds of sense-reporting are being analyzed which exist in hadith text. And it is proved here in this article that no kind of amendment occurred due to sense-reporting.

Painting Into A Corner: The Pedagogic Agenda, the Immersive Mediation (and the Overdetermined Experience) of ‘Play Van Abbe 4’
Authors: Bartholomew Angela
Published: December 2021

Play Van Abbe 4: The Pilgrim, the Tourist, the Flâneur (and the Worker) (2011), the final installment of the experimental, Play Van Abbe program at the Van Abbemuseum – invited viewers to play one of four ‘roles’, each of which entailed a different mode of engagement. The pilgrim sought divine inspiration, the tourist an encounter with something unusual. The flâneur strolled along in passive observance while the worker, not merely a consumer of experience, produced in return. To engender these perspectives role-specific ‘tools’ for art mediation were extended to the exhibition’s visitors. While not explicitly fetishized on pedestals or in vitrines, mediation was the overriding object and subject of Play Van Abbe 4. Works such as Richard Long’s Wood Circle (1977), James Lee Byars’ Hear TH FI TO IN PH Around this Chair (1978), and Oliver Ressler’s What is Democracy? (2009), functioned merely as a backdrop. Each of the artworks included could have been exchanged with any other. In such a situation it is imperative to ask: in the midst of so much discursive and immersive mediation is there any space left in the museum for art?
In the Making, of Objects, Artists, and Publics
Authors: Ganz Blythe Sarah
Published: December 2021

In 1818, at the end of a celebrated teaching career, Joseph Jacotot found himself in a curious position. Exiled to Brussels and knowing no Flemish, he faced the predicament of teaching Flemish students who knew no French. Resourcefully turning to a bilingual edition of The Adventures of Telemachus (1699), Jacotot discarded his habitual role of disseminator of knowledge and instead directed the students to the text, from which they successfully instructed themselves. Born of necessity, the teacher-as-explicator model was displaced by the educator-as-facilitator who framed an experience for student-centered learning through individual experience and collaboration. In The Ignorant Schoolmaster, Jacques Rancière recounts Jacotot’s pedagogical adventure and expounds upon the implications of learning being independent from instruction.[1] This includes the conviction that everyone has equal and unlimited potential to learn, beyond existing bodies of knowledge and the delimiting authority of power structures.
Black Mountain and Beyond – Research Practices between Universities and Museums
Authors: Lehmann Annette Jael , Werner Anna-Lena
Published: December 2021

In 2013, everything began with a few general questions. How can universities and museums benefit from each other? How can they complement one another? Where are their thresholds, and where are common grounds? What is their educational agenda? And finally, can they unite theoretical and curatorial endeavors into, well, what exactly? How could they actually bring theory and practice together? In other words, how could students, scholars, curators, and artists cooperate within one project? As a small team based at the Institute for Theater Studies at Freie Universität Berlin—namely Verena Kittel, Annette Jael Lehmann, and Anna-Lena Werner—we wanted to find answers for these questions, and started an in-depth conversation with a part of the curatorial team of Hamburger Bahnhof – Museum für Gegenwart – Berlin, about opportunities to collaborate. The university is in need of practice, of social experiences with people, and of the expertise of preserving and exhibiting. In turn, the museum is in need of research, of alternatives to public programs, and of creating a fundamental analysis of art historical events, aesthetic questions, and philosophical contributions. On both sides there was not only a desire for supplementation, but also a frustration about the growing economization and instrumentalization of educational institutions. What we were looking for might sound idealistic, but we later figured that this attribute was exactly key to our aim: developing a collaborative practice-based research.

Authors: Boušková Marie , Harák Tomáš
Published: December 2021

The Czech Statistical Office (CZSO) changed the calculation of the total volume of waste and also changed the definition of municipal waste compared to the previous methodology. This was made possible by the wider use of the existing administrative data source, the Integrated Environmental Reporting System (ISPOP). The change in the definition of municipal waste was a response to recent Eurostat activities, which led to a more precise definition. The original method no longer meets this definition.

ASTAXANTHIN MENGHAMBAT PERLEMAKAN HATI DAN PENINGKATAN KADAR SERUM GAMMA-GLUTAMYLTRANSFERASE PADA TIKUS WISTAR JANTAN YANG DIBERI MINYAK JELANTAH
Authors: Pangalela Astrid Amanda , I Wayan Weta  , Iin Indrayani Maker
Published: December 2021

ABSTRACT

Non-alcoholic fatty liver can be triggered by used cooking oil consumption due to the formation of free radicals and the accumulation of fatty acids in the body. Astaxanthin is a powerful antioxidant that may be able to inhibit the pathogenesis of fatty liver. This study aims to determine the effect of astaxanthin in inhibiting fatty liver (steatosis) and levels of Gamma-Glutamyltransferase (GGT) in male Wistar rats given used cooking oil.

An experimental study with Post-test Only Control Group Design was conducted on 36 male Wistar rats aged 3.5-4 months with an approximate bodyweight of 200-210 grams divided randomly into 2 groups. The control group was given 0.42 ml of used cooking oil + 0.5 ml of distilled water, and the treatment group was given 0.42 ml of used cooking oil + 0.2 mg of astaxanthin each day for 14 days. On day 15, blood tests and hepatic histopathology were performed to check  GGT serum levels and steatosis. The comparative test was conducted to compare the results of the control and treatment groups.

The results showed that the mean steatosis and GGT levels in the treatment group were significantly lower than the control group. It can be concluded that giving astaxanthin can inhibit fatty liver (steatosis) and increase GGT serum levels in male Wistar rats given used cooking oil.

Desarrollo económico comparativo en un marco teórico Malthusiano:
Authors: Carrasco Estrada Manuel
Published: December 2021

Este trabajo de investigación, en la forma de una tarea de replicación1, evalúa la validez interna del modelo malthusiano de Ashraf and Galor (2011), quienes proporcionan un marco teórico de crecimiento endógeno y emplean data empírica, entre países, para evaluar la teoría malthusiana y sustentar la importancia de factores geográficos en el desarrollo económico de las naciones. Su propuesta forma parte de investigaciones empíricas sobre crecimiento y desarrollo económico que tratan de analizar factores arraigados en la historia a largo plazo, principalmente a través de canales “biológicos (a través de la transmisión genética o epigenética) y culturales (a través de la transmisión conductual o simbólica)” (Spolaore y Wacziarg, 2013: 325).

Mi evaluación se realiza con respecto a la relación causal proporcionada para explicar la densidad poblacional y el ingreso per cápita en el continente americano en el año 1500 CE. Ashraf and Galor (2011) dividieron la región americana en dos subregiones cuya composición, a la luz del argumento de 'reversión de fortuna' no podría ser apropiado. Sus subregiones no tienen en cuenta los diferentes niveles de desarrollo y el pasado colonial de sus miembros. Así, la réplica de regresiones pertinentes mostrará que una nueva clasificación de los países americanos mejora la validez interna del modelo original, pero, sorprendentemente también, favorece enfoques alternativos desde un punto de vista diferente.

A New Emigrant Creation Strategy with Randomized Sources for Parallel Artificial Bee Colony Algorithm
Authors: Aslan Selcuk , Karaboga Dervis , Aksoy Alperen
Published: December 2021

Dividing the whole population into subpopulations or subcolonies then evaluating them simultaneously is one of the most commonly used parallelization approaches to utilize the computational power of the current systems. However, this type of parallelization strategy decreases the population diversity because of the division of the entire population and needs migrations between subpopulations to maintain the solution diversity until the end of the iterations. In this study, we proposed a new emigrant creation strategy in which the parameters of the best food source being migrated to the neighbor subpopulation is modified with the more appropriate parameters of the randomly determined solution or solutions and investigated its effect on the performance of the parallel Artificial Bee Colony (ABC) algorithm. Experimental studies showed that newly proposed emigrant creation strategy based on randomized solutions significantly improved the convergence performance and solution qualities of parallel ABC algorithm compared to the its standard serial and ring neighborhood topology based parallel implementation for which the best solutions are directly used as emigrants.

In this study, our aim was to investigate gender effects on prefrontal cortex oxygenation. Auditory oddball paradigm used as cognitive task. Prefrontal cortex oxygenation is assessed by monitoring changes in blood oxygenation using functional near-infrared spectroscopy (fNIRS). The fNIRS were recorded during the 'oddball' paradigm in which two stimuli (target and standard) were presented in random order. Subjects were asked to press a button in response to the target stimulus. 12 male healthy children and 9 female healthy children were included the study. As a result; it is observed that the males exhibited higher prefrontal activation during auditory oddball task than females. This results suggest that gender had an effect on prefrontal cortex oxygenation therefore gender matching is important for studies of brain function using fNIRS.

Published: December 2021

The work shows the efficiency of using the SСADC reagent as an additive in cement-polymer mixtures. It also outlines physicomechanical properties of the cement slurry and the stone formed on their basis at temperatures of 22 C and 80 C. The main regularities of the formation of structures of various levels in cement-polymer solutions are revealed, depending on the degree of filling and the type of introduced modifications of the SСADC reagent. It was found that an entangled fibrous structure is formed between the hydrated cement minerals and the complex additive SСADC. At a concentration of 0.2%, it provides a self-healing effect for a damaged cement stone, and also improves the properties of cement-polymer grouting mixtures, contributing to a decrease in the filtration rate of the solution to 30%, an increase in bending strength by 25-27% and by 36-42% in ultimate strength for compression.

Yields variability as a determinant of production risk in agriculture
Authors: Smolik Adam
Published: December 2021

Agricultural activity is exposed to a number of adverse external factors known as production risks, which affect the quantity and value of production. One of the measures of production risk assessment in crops production is yields variability. The aim of the study is to determine the scope of the variability of the yields of selected agricultural crops on the basis of various sources of data covering the years 2015–2019. The study uses aggregated official statistics data compiled by Statistics Poland, published in the Statistical Yearbook of Agriculture, and individual data from the Polish Farm Accountancy Data Network (FADN), which takes into account commercial farms. The analysis of the differences in crops variability determined on the basis of different sources of information was carried out using basic statistical parameters: the arithmetic mean, standard deviation and the coefficient of variation. The research shows that the variability of yields in Poland depends not only on the type of crops, but also on the location of the production. Moreover, it indicates a greater stability of crops production among commercial farms when compared with farms in general. The comparison of the values of the coefficient of variation calculated from individual data with the values calculated on the basis of the average yields indicates fundamental differences which should be taken into account when applying the variation coefficient to assess production risk and, consequently, to optimise insurance tools.
COHERENCE OF PUBLIC POLICIES IN POLAND IN THE PERSPECTIVE OF THE PROCESS ON REACHING COMPLETED ADULTHOOD
Authors: Grotowska-Leder Jolanta , Dziedziczak-Foltyn Agnieszka
Published: December 2021

The issue of transition into adulthood, treated as a complex, multi-dimensional and multi-stage social process, is not explicitly an object of interest to public policies, including social policy. The context of the life course policy mentioned in the analyzes is justified by the institutionalization of tasks related to functioning in society typical of completed adulthood: completing education, taking up employment, setting up your own household and family. The so-called delayed transition into adulthood means an increasingly later implementation of these tasks. The barriers to reaching completed adulthood discussed in the article mean that this process becomes a social problem that should be prevented by public activities. The article synthetically summarizes the results of the research “Public policies for full adulthood in Poland” (National Science Center No. 2014/15/B/HS5/03284). The aim of the considerations is to indicate the level of coherence and coordination in the creation and implementation of political and institutional instruments that would support young adult Poles in the process of reaching full adulthood in the above-mentioned dimensions. The conclusions from the research prove the need to separate the transition to adulthood regime in Polish social policy (public policies).
ENVIRONMENT AND LIVING PLACE FOR ELDERLY PEOPLE
Authors: Bojanowska Elżbieta
Published: December 2021

Every person’s place of residence is part of their everyday living environment and largely determines their sense of security, while housing conditions affect the quality of life. Therefore, proper housing conditions, meeting the needs of older people and a friendly local environment have an impact on experiencing old age. The research shows that the elderly want to stay in their own house/flat as long as possible, in a familiar and friendly environment. Therefore, it is equally important to adapt a flat or a house to the possibilities of older people, as well as appropriate shaping of the public space, enabling them to move freely. Moreover, aging in the place of residence should mean the launch of numerous services adapted to the changing needs of this very diverse group of elderly people over time, which is part of the de-institutionalization process.

La cooperación internacional para la paz en Colombia: divergencias y convergencias entre Estados Unidos y la Unión Europea.
Authors: Davide Riccardi  , Taborda Jairo Agudelo
Published: December 2021

Este artículo examina acciones e intenciones de las políticas de cooperación internacional para la paz que Estados Unidos y la Unión Europea implementaron en Colombia durante las últimas dos décadas. Mediante una revisión de la principal literatura especializada sobre el tema, se halla cómo ambos donantes encontraron una proficua oportunidad para experimentar su propio modelo de cooperación internacional. Desde el lado estadounidense, el significativo apoyo militar respondió a lógicas propias de carácter interno (war of drugs) y externo (fortalecimiento del principal aliado regional). Desde la Unión Europea, más allá de la retórica discursiva que rechazó cualquier ayuda militar, las dinámicas de fragmentación interna dada por diferentes posiciones particulares de sus países miembros y los contradictorios intereses económicos, frustraron su posibilidad de consolidarse en Colombia como una “potencia civil global”. Queda en evidencia un importante apéndice en común dado por la firma de acuerdos de libre comercio con este país latinoamericano que, tras entrar ambos en vigor a distancia de pocos años, reforzaron una lógica de “cooperación neoliberal”, funcional al mantenimiento del statu quo económico internacional desigual.

Published: December 2021

Desenvolver tecnologias para crianças Surdas traz desafios inerentes às particularidades delas, bem como desafios aos meios de avaliação dessas tecnologias. Mesmo jogos produzidos por meio de processos colaborativos de design necessitam de avaliação da adequação à proposta original e ao público-alvo. Nesse sentido, este artigo apresenta os resultados do processo de avaliação preditiva de um jogo educacional projetado por e para crianças surdas utilizando duas técnicas: avaliação heurística e avaliação por especialistas. Houve a identificação de mais pontos de melhoria na interação e pôde-se fazer uma reflexão para além da usabilidade, refletindo-se sobre possíveis práticas de aplicação do jogo, como a possibilidade de trabalhar aspectos de cooperação.

Penser la formation, l’insertion professionnelle et l’exercice d’une profession dans le cadre d’un développement durable des ressources humaines : enjeux et perspectives dans un monde sous tension
Authors: Desbiens Jean-François , Mukamurera Joséphine , Perez-Roux Thérèse
Published: December 2021

Le développement durable est un thème d’actualité dont on peut questionner la récupération lorsqu’appliqué au travail destiné à autrui. Les sept contributions de ce numéro thématique s’ancrent dans les domaines de la gestion, de la santé et de l’éducation. Elles examinent, d’une part, comment la formation améliore la préparation à l’exercice d’une profession, cultive le sens de la gestion socialement responsable, module les dynamiques identitaires de même que les reconversions professionnelles. D’autre part, elles questionnent les répercussions d’une certaine culture managériale et professionnelle sur le sens donné par les travailleurs à leur mission, la reconnaissance de leur expertise, leur satisfaction au travail et leur attachement à l’emploi.
