Published: May 2021

Introduction: Diabetes mellitus is a metabolic disease that is a primary public health consideration. Low Vitamin D levels are linked to type 2 diabetes (T2DM), diminished insulin release, and enhanced insulin resistance in humans and animals. Vitamin D is also involved in the regulation of calcium and phosphorus homeostasis. Oxidative stress and antioxidant imbalances are important for the progression of diabetes as well. In this endeavor, the levels of vitamin D, calcium, phosphorus, and evaluation of the oxidant- antioxidant factors of malondialdehyde (MDA) and total antioxidant capacity (TAC) in healthy and diabetic people were compared.Methods: This descriptive-analytical study was conducted in 2020 in Shiraz, Fars province, Iran. The population included 40 T2DM patients (with HbA1c equivalent 6-8) without comorbidities, 20-60 years old for both genders, and 40 healthy individuals (female and male between 20-60 years old without comorbidities). The high-performance liquid chromatography (HPLC) method was adopted for measuring Vitamin D and for measuring other levels, the colorimetric method was used. Using SPSS 22, statistical analysis was performed. The Mann- Whitney U test for quantitative data was applied. P<0.05 was deemed significant.Results: There was a statistically significant difference between the two groups when it came to the means of vitamin D and MDA. In the diabetic group, vitamin D levels were lower (p=0.001) and MDA levels were higher (p<0.001). Comparing the level of calcium and phosphorus in diabetics and healthy people revealed no significant difference. This result was also true for the TAC test.Conclusions: According to our results, the mean of vitamin D in T2DM was significantly lower than healthy people and MDA in T2DM significantly increased compared to the control group, suggesting that increasing the activity of this enzyme in the development of secondary complications in diabetic patients is a predisposing factor.Keywords: Vitamin D, Diabetes mellitus, HPLC, Oxidative stress
Does Dictionary Use Affect Iranian EFL Learners’ Lexical Density in Writing?
Authors: Abdi Reza
Published: May 2021

An important, but rare question in EFL writing is whether learners should use dictionaries or not. The problematic state of this question prompted the present study. This study assesses research on the question of "does dictionary use affect Iranian EFL learners' lexical density or not". In order to answer the above question, a total of seventy four Iranian EFL intermediate learners (male and female aged from 17 to 26) from Nasr English Institute, Ardabil, Iran took part in this research study. The participants were high school and college students whose L1 was Azari-Turkish. They were appointed to three experimental groups and one control group randomly. Since this research explored the effect of dictionary use on learners' writing, the three experimental groups were labeled as EPD, PED and EED. The study had a pre-test, post-test 1 and post-test 2 design. All four groups took a proficiency test named Solutions Placement Test. ANOVAs proved their homogeneity (F=.002, p=1.000). Then the participants completed three pieces of writing, each including a writing task with similar level and number of words but a different topic. Experimental groups had two treatment sessions after pre-test and they had a two-week interval after post-test 1. During the test, experimental group one (EPD) used English-to-Persian dictionary, meanwhile, experimental group two applied Persian-to-English dictionary and finally, experimental group three took the advantage of English-to-English dictionary. Nevertheless, the compassion group received no dictionary and no treatment sessions. To fulfill the purpose of the study, a One-way ANOVA was applied to figure out the differences among the performance of the four groups. Although, there observed tangible improvement in the scores, the results ran counter to the expectations and showed no significant difference.
Acquisition of Future Perfect Progressive Tense by Persian L2 Learners of English: The Interpretability Hypothesis
Authors: Sadri Zahra , Khosravi Anahita
Published: May 2021

The issue of non-native speakers’ divergence from L2 input has gained popularity in the field of second language acquisition during the previous decades. Many significant scholars have joined the discussion and tried to explain this phenomenon through various models and frameworks. In this regard, the present study discussed domains of divergence within the framework of interpretability hypothesis. To this end, syntactic structures of future perfect progressive tense were compared in English and Persian. To examine the validity of Interpretability Hypothesis (IH), 30 Iranian L2 learners at intermediate and advanced levels were selected based on the oxford quick placement test. Further, learners were required to answer two translation tests containing English to Persian (comprehension test) and Persian to English (production test) sentences. Results revealed that learners had no problem in comprehension of this tense; however, when it came to production, they experienced some instances of divergence. Based on the findings, underpinnings of IH are supported in the sense that the logically interpretable English future perfect progressive tense poses little problem for learners whose L1 lacks the tense phonologically. Moreover, the results showed that Persian learners resort to some other compensatory tenses to express futurity in their L1.
A Crosscultural Study on the Correlation Between Achievement Levels and Motivational Types of Values of Language Learners
Authors: Cubukcu Feryal
Published: May 2021

Most social scientists view values as deeply rooted, abstract motivations that guide, justify or explain attitudes, norms, opinions and actions. Values are basic orientations presumed to underlie and influence individual variation on many of the constructs that researchers from different disciplines wish to study. Since 1950s the main features of the conception of basic values implicit in the related literature are: 1. Values are beliefs, cognitive structures that are closely linked to affect. 2. Values refer to desirable goals. For example, social equality, fairness and helpfulness are all values. 3. Values transcend specific actions and situations. Obedience and honesty, for example, are values that may be relevant at work or in school, in sports, business and politics, with family, friends or strangers. 4. Values serve as standards or criteria. 5. Values are ordered by importance relative to one another. Cultures and individuals can be characterized by their systems of value priorities. Among all the scales, The Schwartz Value Survey (SVS) (1992) is currently the most widely used by social and cross-cultural psychologists for studying the individual differences in values. Schwartz derived ten, motivationally distinct, broad and basic values from three universal requirements of the human condition: needs of individuals as biological organisms, requisites of coordinated social interaction, and survival and welfare needs of groups. The ten basic values are intended to include all the core values recognized in cultures around the world (power, achievement, hedonism, stimulation, self-direction, universalism, benevolence, tradition, conformity, security). To primarily showcase whether there is a correlation between the success levels of the language learners and their motivational type of values, and secondly to explore whether this is culture specific or not, 56 language learners participated in the study and The Schwartz Values Questionnaire was administered. The study is expected to yield insight into the pursuit of the correlation between the proficiency levels of the language learners and their motivational types of values.

Published: May 2021

Coronavirus disease 2019 (COVID-19), the highly contagious infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease has shown to put an enormous burden on the society and is a challenge to the physician owing to its infectivity, complications, morbidity and absence of proper medication. As medicine is an ever-changing science new research and clinical experience broaden our knowledge and bring changes in drug therapy. COVID-19 is now spreading throughout the world because of its high infectivity and communicability. Also there is a lack in the proper management of the disease. Because there is no definite and specific treatment for patients with COVID-19, some antiviral agents are prescribed to the patients, depending on their condition and location. It is widely accepted that the world will not return to its prepandemic normalcy until safe and effective vaccines become available and a global vaccination programme is successfully implemented. As COVID-19 is new to humankind and the nature of protective immune responses is poorly understood, it is unclear which vaccine strategies will be most successful. This review attempts to educate the readers about the molecular and structural complexity of COVID-19 virus; its clinical manifestations in humans; immune responses and a special reference on the various adaptive immune responsive strategies including vaccines and its limitations.

Anomaly Detection is system which identifies inappropriate human behavior. One of the major problems in computer vision is identifying inappropriate human behavior. It is crucial as activity detection can help many numbers of applications. It can benefit applications like image monitoring, sign language recognization, object pursue and many more. Many alternatives are there such as low-cost depth sensors, but they do have some drawbacks such as limited indoor use also with lower resolution and clamorous depth information from deep images, it becomes nearly impossible to assess human poses. In order to resolve the above issues, the proposed system plans to utilize neural networks. One of the major research area is to recognize suspicious human behavior in video monitoring, in the field of computer vision. Several surveillance cameras are situated at places like airports, banks, bus station, malls, railway station, colleges, schools, etc to detect suspicious activities such as murder, heist, accidents, etc. It is a tedious job to detect and monitor these activities in crowded places, to trace real time human behavior and classify it into ordinary and unexpected scenarios the system needs to have a smart video surveillance. The experimental results show that the proposed methodology could assuredly detect the unexpected events in the video.

The world we live in today has become very advanced today. As we can see in the past we used lock and key system for centuries to lock the doors. In many cases we as humans have lost our keys and for getting in we had to break the door and which would be much costlier repairing or installing a new door. Robberies were also a security threat and making living away from the house more frustrating and stressful. But as we are advancing technologies in various fields our locks also need to be upgraded. Keeping that in mind we have designed a facial recognition-based security lock system using Raspberry pi as the main controller of the system. Our system uses a camera which is attached to the raspberry pi and the controller is programmed using opencv in such a way that only the registered faces could open the door.

Published: May 2021

The trend of healthy eating determines several areas of modern consumer trends: the Ukrainian buyer pays more attention to the naturalness of ice cream and more carefully analyzes the ingredient composition of the product. More popular is ice cream, which does not contain synthetic dyes and flavors and is lower in sucrose. The article substantiates the use of dates processing products in ice cream technology. The aim of the work was to develop ice cream technology with partial and complete replacement of sucrose with date paste and date syrup. The research was conducted at the Department of Milk and Dairy Products Technology at Stepan Gzhytskyi National University of Veterinary Medicine and Biotechnologies Lviv. The raw materials used for research met the requirements of current regulations in terms of quality and safety. Date paste was made independently, hazelnut oil was added to it. Organic date syrup was used under the trademark Bio Planet. Four ice cream recipes were developed and technological operations of ice cream production with dates processed products were worked out. Denise 855 was used as a stabilizer and emulsifier in the ice cream recipe, which gives an unsurpassed creamy taste and homogeneous structure and provides the initial air distribution and stable whipping. In the study of organoleptic characteristics of ice cream, it was found that all samples had a similar sense of aroma and taste – with the taste of dates. The addition of date syrup improved the taste of ice cream. Taste indices increased significantly with increasing concentration of date syrup. Complete replacement of granulated sugar with date syrup significantly lowered the pH and increased acidity. In addition, the replacement of sucrose with date processed products has been shown to increase the viscosity of ice cream. The lowest viscosity value was observed in the control sample, while the highest viscosity value was obtained when the sugar was completely replaced with date syrup.

Published: May 2021

Currently, the creation of a range of new products that improve human nutritional status is a timely and urgent problem facing scientists in the food industry. In food technology it is effective to use functional ingredients that have enhanced protective and improved technological properties. It is possible to confidently attribute the components of plant origin, namely, dietary fiber and plant phospholipids, to such substances. Phospholipids are a group of essential substances that are irreplaceable and enter the human body only with food. Phospholipids cannot be formed independently in the human body, but perform important functions that have a positive effect on the body: they restore cell walls; they are involved in lipid metabolism, as well as reducing the risk of cholesterol formation; they actively participate in the delivery processes of biologically active substances to cells, etc. A rich source of biologically active substances are flax seeds, its medicinal properties have been known for centuries and are recognized by official medicine. The influence of flax seed mucilage and phospholipids in the formulation of red main sauce on rheological and physical parameters was investigated. Samples of sauces with replacement of 50 and 100% of flour for flax polysaccharides and 30 % of animal fat for vegetable phospholipids were developed. The change of effective viscosity and density of the developed sauces is investigated. It was found that at a shear rate of 0.3333 s-1 the viscosity of the control sample is 14.32 Pa·s, of the same one with the replacement of 50 % flour and 10 g of fat and 100 % flour and 10 g of fat, respectively, is 16.49 and 19.6 Pa·s. This replacement in the experimental samples is accompanied by a slight increase in density. In order to substantiate the functional orientation of sauces in the introduction of herbal additives, studies were conducted to determine the antioxidant activity (AOA) of the developed sauces and their components. It was found that the maximum AOA a sauce with herbal additives has, which for 90 minutes is able to “quench” 89 % of the radicals formed in these conditions in the model system. Adding sauces to ready meals, even in small quantities, help to increase the nutritional value and attractiveness of the consumed food. Therefore, the effect of additives on the consumer characteristics of sauces was investigated. It is established that the developed types of sauces have a characteristic structure, creamy and homogeneous consistency, pronounced taste and aroma. The conducted complex of researches allows to state with confidence that use of available vegetable raw materials instead of the ingredients possessing the raised food value, allows to reduce energy value and to expand the range of sauces of functional orientation for restaurant enterprises.
Dignidade Da Pessoa Humana: Por Um Conteúdo Mínimo Apreensível Pelo Direito
Authors: Nascimento Amanda Pinheiro
Published: May 2021

O Direito iniciara o seu nascimento no “mundo” dos saberes pela pretensão de pureza e isenção. Logo, reduziria o ordenamento jurídico a um encadeamento lógico de proposições. Ocorre que, na esteira do tempo – vide as duas grandes guerras mundiais – o Direito fora evocado para resolver demandas complexas, as quais uma ciência purista seria incapaz de resolver. Daí o estudo do direito passara por uma nova mutação, por intermédio da qual, o mesmo deve ser permeado pela moral e pela ética. Contudo, exsurge uma nova problemática, a saber, dentre as inúmeras morais possíveis, qual delas deve ser utilizada pelo Direito. A dúvida repousa na possibilidade de uma apreensão objetiva, entre as diversas moralidades existentes. Procuramos de forma sucinta defender a ideia de que é possível ao menos uma hierarquização mínima de valores morais ou de princípios éticos, a exemplo da declaração de Direitos Humanos. Para tal intuito, utilizamo-nos do estudo comparativo entre as obras dos escritores e filósofos Martha Nussbaum e Heidegger, pois acreditamos que os autores “conversam” quando enxergam no tempo uma importante chave cognitiva acerca da manifestação dos conceitos, para Nussbaum, e da verdade para Heidegger. Isso quer dizer que, é possível encontrar valores mais nobres, em detrimento dos menos nobres, em determinado espaço de tempo, que estejam presentes em diversas culturas. Sendo assim, apresentamos a conclusão de que haveria a possibilidade de estabelecer um conteúdo mínimo moral, referente à dignidade da pessoa humana, a ser aplicado aos seres humanos universalmente, como fruto de um constructo social, ainda que tal moral possa ser passível de uma revalidação futura, em virtude da apresentação de novos eventos, como defendem os autores.

Cet article présente une analyse de la propagation du SRAS-CoV-2 à Amapá en utilisant trois approches. Dans le premier, le modèle ICL de la pandémie appliqué au Brésil a été utilisé pour mettre en œuvre une projection linéaire comparative pour la population Amapá. La deuxième approche a été développée avec la solution à court terme du modèle SIR standard, où il a été montré que le comportement exponentiel typique décrit de manière satisfaisante les données pour les premières semaines de l’épidémie, mais peu de temps après, il y a des écarts précoces dus à une soudaine décélération de l’évolution temporelle nombre de cas dû aux mesures d’isolement. Ce nouveau régime est décrit de manière appropriée avec la troisième approche qui est basée sur le modèle vSIR qui est une variante du modèle SIR. Les résultats présentés permettent, d’une part, de mieux comprendre les scénarios déjà rencontrés par la population et, d’autre part, de fournir des projections à court terme qui seront constamment mises à jour sur le lien [11].
IS GENDER PLAYS A ROLE IN WORKPLACE?
Authors: Thiranagama Waruni
Published: May 2021

Women participation in the workplace has increased dramatically in recent years, yet the women in the the highest positions of the organizations are still rare. Women face greater barriers that are different from those of their male counterparts when moving up the career ladder. Glass-ceiling refers to situations where the advancement of a qualified person within the hierarchy of an organization is halted at a particular level. The paper discusses the glass ceiling of women employees and the nature of the glass ceiling among the women in society. Further it provides a critical analysis on the glass ceiling by giving empirical evidence from different authors. Evidence shows that glass ceiling is still prevalent around the world. However, cooperates do not believe the existence of glass ceiling, which makes the situation worse by hiding reality. They argued that glass-ceiling effect is a myth created by society. Moreover, it is argued that the lack of women employees in the top positions of the organizations is not because of the glass-ceiling was there but because the factors within the women employees hinder their movements to the top positions in the organizations. Hence glass ceiling remains still debatable.

This paper aims to study the transformation of money in the United States using qualitative content analysis and predict the stability of the internal exchange rate of money by comparing the internal exchange rate of commodity money proxied by gold against crude oil internally. The exchange rate of fiat money proxied by the USD against crude oil and the internal exchange rate of synthetic money proxied by bitcoin against crude oil use the autoregressive threshold (TAR) method in the exchange period. In the great depression, fiat standards, subprime mortgage crisis, Europe experienced a debt crisis until 2017 (1960 - 2017). We compare the internal stability of money for each period in the aggregate using TAR to describe the overall fluctuation of internal exchange rate stability. So it can be seen that the behavior of data movements based on the crisis period experienced is the basis for predicting the stability of the internal exchange rate in the future.
Studying the Rise and Fall of Powers: Insights From Neo-Khaldunian Thought
Authors: Gamal Shehab El-Mekdad
Published: May 2021

This paper sheds the lights on the ideas of Ibn Khaldūn in conjunction with the thoughts of Malik ibn Nabi on the rise and fall of powers and posits that the psycho-sociological analysis of Ibn Khaldūn can be applied to the rise and fall of the contemporary political powers. the paper argues that this validity stems from the comprehensiveness of the Ibn Khaldūn analysis which explains how the political power generates from the stage of the idea, flowing to the stage of states, reaching ultimately to the civilization which is the most progress status sought by any power. by combing the ideas of these two scholars, this paper proposes what can be called the “Neo-Khaldūnian” approach to study the rise and fall of the powers in the modern world.

This study evaluated the heavy metals hazard of palm wine from Raphia species sold in Wilberforce Island, Bayelsa State Nigeria. Triplicate samples were obtained from six locations in Wilberforce Island and analyzed using atomic absorption spectrophotometer. The health risk associated with heavy metal contaminants was calculated following standard protocol. Results of heavy metals in palm wine were in the range of 0.157–0.319mg/L, 0.554–0.983mg/L, 0.000– 0.2289mg/L, and 0.123–0.5299mg/L for zinc, iron, cobalt, and copper respectively. There were significant discrepancies (p < 0.05) in the palm wine samples across various locations for the different parameters. Metals such as cadmium, chromium, nickel, and lead were not detected in palm wine, indicating that toxicity related to them is non-existent. However, zinc, cobalt, and copper were observed at low concentrations, while iron levels exceeded regulatory comparison. This is possibly an indication of iron-rich soils which are prevalent in the area. It may also have resulted from activities releasing this metal within the study area. Average daily intake and hazard quotient and health index (< 1) indicate no adverse acute health effect. To forestall potential health risks associated with heavy metals in palm wine, there is a need to regularly evaluate heavy metal concentrations.

Ovaj rad bavi se međuodnosom političkih preferencija i političkih orijentacija studenata i njihovih roditelja. Rad je teorijski organiziran u okvirima sociologije znanja s posebnim osvrtom na određene
dimenzije političke socijalizacije kao dinamičnog procesa – konstantne dijalektike primarnih i sekundarnih socijalizacijskih aktera. U radu se istraživala važnost određenih aktera u životima studenata u formiranju njihovih političkih identiteta. Provedeno je istraživanje nad populacijom studenata Sveučilišta u Zagrebu. Uzorak je obuhvaćao 500 studenata s fokusom na ispunjenje kvota po spolu i području studijskog programa. Samo istraživanje polazilo je od tri osnovna istraživačka pitanja; (1) U kojoj mjeri i na koji su način povezane političke preferencije studenata i roditelja? (2) U kojoj mjeri su povezani političko ideološki stavovi (političke orijentacije) roditelja i studenata (u smislu lijevo/centar/desno)? (3) U kojoj mjeri su povezani politički stavovi (preferencije i orijentacija) studenata sa stavovima očeva te stavovima majka? Istraživanje je pokazalo kako su, u ponuđenim
akterima, najveće značenje za formiranje političkog identiteta za studente i dalje imali njihovi roditelji. Potvrđena je i statistički značajna povezanost političke orijentacije studenata i one njihovih roditelja. U deskriptivnom smislu, veća usklađenost i političkih orijentacija i političkih preferencija vidljiva je na desnom političkom spektru nego li je to slučaj s lijevim političkim spektrom (iako i tamo postoji povezanost).

Glavni je cilj ovog rada istražiti koliko su hrvatski novinari upoznati s
profesionalnim standardima novinarstva, postoji li povezanost između obrazovanja i radnog iskustva novinara i poštovanja profesionalnih načela, koji unutarnji i vanjski faktori imaju presudan utjecaj na njihov rad, kakvim pritiscima su izloženi u svakodnevnom radu te postoji
li urednička cenzura u hrvatskim medijima zbog koje novinari ne poštuju
profesionalna pravila ponašanja. Da bi se dobili odgovori na istraživačka pitanja provedeno je istraživanje metodom ankete na uzorku novinara i urednika dnevnih novina, elektroničkih i online medija.
Pragmalingvistički pristup
analizi humorističnog sadržaja o COVID-19 pandemiji
Authors: Borić Iva , Hadžić Jelena
Published: May 2021

Pojava pandemije COVID-19 rezultirala je mnogim neobičnim i neočekivanim
situacijama kojima su gotovo svi stanovnici Republike Hrvatske bili izloženi na svim područjima života. Navedena promjena društvene situacije uzeta je kao primjer toga da kontekst mijenja značenje jezičnog iskaza, odnosno, osim uobičajenih značenja sadržaja, pojavljuju
se i nova značenja koja prije pojave pandemije nisu postojala. Za pragmalingvističku analizu sadržaja koja je primijenjena u ovom radu, ključ je kontekst po kojem dešifriramo značenje. Svrha rada je istražiti
vrste razgovornih maksima koje se krše u jezičnim iskazima humorističnog sadržaja, prikupljenog tijekom ožujka 2021. Sadržaj se sastoji od primjera prikupljenih iz vrela interpersonalne i grupne komunikacije.

Upotreba jezika kroz humor kao narativ u prvi plan stavlja i samu snagu tropa, kao što su metafora, metonimija, sinegdoha, implikatura itd. Bez njih se gubi mogućnost „širenja horizonta“, odnosno istraživanje teritorija između običnog i neobičnog. Budući da većina humora već samom formiranju krši neke od maksima, moguće interpretacije proučavanih
humorističnih jezičnih iskaza, primjeri su kako kontekst i kršenje maksima, kao osnovnih pretpostavki racionalnog razgovora dovode do novog
značenja i humorističnog efekta (ili dodatnog humorističnog okidača, različitog od postojećeg, u novom kontekstu).

Published: May 2021

Purpose. The justification of environmentally significant indicators for information knowledge base of specialized GIS the formation to control and management of metallurgical slag waste. The research methodology provided for the scientific substantiation of the selection of certain ecologically significant characteristics and indicators of metallurgical slags on the basis of systematization and generalization of known data on their properties, as well as analysis of the values of certain indicators or ranges of their possible changes necessary to determine the resource potential of the slags and their environmental hazard. Research results. The concept of control and management of slag waste based on the corresponding specialized GIS is proposed. In its knowledge base, indicators and characteristics of steelmaking, cupola and the most massive – blast furnace metallurgical slag were selected. The resource potential of slags is envisaged to be assessed by the volume of their accumulation and the possibility of utilization or use in certain industries, and the environmental hazard – by chemical composition. Scientific novelty is as follows: - when determining the resource potential of slags, its mass in the dump is recommended to be determined by their volume obtained by GIS tools, taking into account the density of the slag material, on average – 2850 kg/m3 ± 5%. - the process of emission of iron and manganese into distilled water reaches a relative level of 0.95 already at the end of the first day and is maintained at the beginning of the third, after which it turns into a decreasing sigmoid curve, reaches an asymptote maximum value, after about a tenth day, and then changes little; the emission of vanadium and titanium in an aggressive solution has the form of an exponential. - the granulometric composition of slags, determines the volumes of its storage through the effect on the bulk density, it is proposed to characterize the minimum and maximum size of particles or lumps for waste slag – 1.6 mm and 250 mm, and for granulated blast-furnace slag and silicomanganese slag with an average median size of granules – 1.31 ± 0.15 mm and 1.54 ± 0.2 mm, respectively. Practical value. Specific values or ranges of possible changes in indicators of slags resource potential, as well as their environmental hazard to the environment by factors that, in aggregate, determine the migration of pollutants from the slag into waste water, have been determined, soil filtration, and emissions into the atmosphere.
