Confidence in digital money: Are central banks more trusted than age is matter?
Authors: Koziuk Viktor
Published: January 2021

The virtual nature of digital money is fueling the conflict between usability, functionality and trust in the digital form. Institutional trust drivers should move forward in understanding the nature of confidence in digital money. Do central banks digital money (CBDC – central bank digital currency) and private cryptocurrencies demonstrate the same or different trust patterns? The paper used the general regression method to discover the relationship between trust in different forms of digital money and selected variables that may generate this trust. Simple empirical tests were sufficient to find the fundamental importance of age as a confidence driver relevant to CBDC and cryptocurrencies. It is found that traditional factors associated with the inflation history and quality of monetary order (central banks independence and rule of law) do not play a role in the case of CBDC, but are important in the case of cryptocurrencies. Structural features (like FinTech development or social trust) that should support trust in digital money are not found to be important. Societies with larger fraction of younger generations demonstrate higher confidence in centralized and decentralized forms of digital money. This challenges the traditional approach to money and calls into question the future role of monetary stability institutions in the digital age. Digitalization is perceived as an improvement in welfare only when fiat money institutions become fragile. The efficiency and credibility of central banks are not a bonus to confidence in CBDC. This is a challenge for the institutional design of the future digital-based monetary order.
Geopolitical Aspect of Migration in the Post-Yugoslavian Chronotope: a Historical Sociology Approach
Authors: Vukčević Nemanja
Published: January 2021

Migration processes are complex phenomena. They are consequences of international political movements and power redistribution, which makes it possible to study them in their geopolitical aspect. The article contains a detailed review of historical sociology, substantiated by geopolitical examples from Ancient Rome, Byzantium, Ottoman Empire, World Wars I and II, etc., against the post-Yugoslavian chronotope. The research was based on the methods of historical sociology, as well on the principle of unity of logic and history. The author drew analogies between the abovementioned historical events and the contemporary migration crisis in post-Yugoslavian countries in order to forecast its possible outcome and prevent a social collision. The paper focuses mostly on the case of the Republic of Serbia. Migration management should take into account that history repeats itself: if certain conditions always produce the same result, it is only logical to expect this result next time the same conditions occur. In sociology, this approach remains poorly represented, even though it can produce reliable and long-term solutions in migration management, unlike short-term and superficial ad hoc measures. Previous decisions have led to the ghettoization of migrants, which threatens to escalate into a social conflict. Therefore, achievements of historical sociology can offer a new approach to this problem.
Methodological Approaches to Estimating the Progress of Universities in Lean Production
Authors: Chelombitko Anna
Published: January 2021

The rapid development of lean production in Russian universities needs new methodological approaches to assess the ongoing processes. The research objective was to develop a new methodological approach to the progress assessment of lean production at universities. The approach is based on the effect of principles, tools, and scope of lean production on its qualitative and quantitative indicators, e.g. the number of methods, projects implemented, work standards, etc. This approach makes it possible to determine the development level of lean production systems on the basis of quantitative indicators, as well as to compare different universities with each other. The experiment featured two universities of the Association of Lean Universities, namely Maikop State Technological University and Kuban State Medical University. In terms of the main indicators, both universities appeared to be quite similar: they had almost the same number of implemented projects, mapped flows, and visualizations, as well as the level of time savings and stakeholder satisfaction. This result can be explained by the general policy of implementing lean production, as well as by a shared scientific and methodological basis. Kuban State Medical University had a slightly greater coverage of training in the field of lean production, standardization, etc. Maikop State Technological University proved to be more active in studying the needs of stakeholders and student involvement. Both universities paid insufficient attention to the cost assessment of the results of lean production. They also had poor management indicators for sustainability processes. The developed methodology may be of interest for university management, since it helps to substantiate decisions made on the basis of a comparative analysis. It can also serve as a basis for a new ranking of lean universities.
Dualistic Monarchy: Problems of Identification
Authors:   Irkutsk Institute (Branch), All-Russian State University of Justice, Parfenova Т.А.
Published: January 2021

The purpose of this study is critical understanding the basic, well-established classification of forms of government used in the theory of the state, in terms of identifying the dualistic monarchy. In the scientific and educational literature, there is no unity and certainty in describing the monarchy of the chosen type: some scientists tend to believe that this is a monarchy conditionally and slightly limited, while others believe that this is the format of a modern monarchy with a strong but limited power of the head of a state by Parliament. Against the background of such discrepancies, the term continues to be actively used. The scientific article calls for the development of a unified approach to understanding the dualistic monarchy as a form of government, where there is a dualism of legislative and executive power: on the one hand, the inherited head of a state concentrates executive power in his hands, on the other hand, there is a legislative body formed by the population, capable to exercise its power independently of the monarch. As an independent type, the author proposes to distinguish a quasi-absolute monarchy, where the head of a state has full executive power and a strong influence on the legislative power in terms of its formation and influence through an absolute veto. A quasi-absolute monarchy is not identical with an absolute monarchy: this study was carried out by the author earlier, and there are relevant references in this work.

Authors: Patel Dhaval B. , Parmar Jagruti A. , Patel Siddharth S. , Naik Unnati J. , Patel Hitesh D.
Published: January 2021

The synthesis of ester-containing heterocyclic compounds via multicomponent
reaction is one of the preferable processes in synthetic organic chemistry and medicinal
chemistry. Compounds containing ester linkage have a wide range of biological applications
in the pharmaceutical field. Therefore, many methods have been developed for the synthesis
of these types of derivatives. However, some of them are carried out in the presence of toxic
solvents and catalysts, with lower yields, longer reaction times, low selectivities, and byproducts.
Thus, the development of new synthetic methods for ester synthesis is required in
medicinal chemistry. As we know, multicomponent reactions (MCRs) are a powerful tool for
the one-pot ester synthesis, so in this article, we have reviewed the recent developments in
ester synthesis. This work covers a selected explanation of methods via multicomponent reactions
to explore the methodological development in ester synthesis.

Authors: Zhang Zhen , Que KeTing , You Yu , Zhao XiaoPing , Wen DiGuang , Feng ZhiHao , Liu ZuoJin
Published: January 2021

Objective:

The purpose of this study was to explore the effect of TRAF1 on phenotypic
changes of KCs in I/R in liver transplantation.

Methods:

SD rats were randomly divided into sham group and liver transplantation I/R group. KCs
were extracted from rat livers in each group. KCs were transfected by lentivirus of si-TRAF1 or
si-HOIP, and induced by Lipopolysaccharide (LPS). Flow cytometry was used to detect cell apoptosis.
Western blot and RT-PCR were used to detect the protein and mRNA expression levels.

Results:

Compared with the sham group, the expression levels of TRAF1, TNF-α and IL-1β were
significantly increased in the I/R group (P<0.05). In addition, compared with the control group, the
expression levels of NF-κB (P65 and p-P65) and M1 phenotype (TNF-α and IL-1β) were notably
increased in si-TRAF1 and si-HOIP group (all P<0.05). Furthermore, the levels of Linear Ubiquitin
Complex (LUBAC) were markedly increased in LPS-induced KCs in comparison with the control
group (P<0.05). Moreover, compared with the control group, the expression levels of P65, p-P65,
TNF-α and IL-1β were notably decreased in the si-TRAF1 and si-HOIP group (P<0.05). The expression
levels of P65, p-P65, TNF-α and IL-1β were significantly increased in si-TRAF1 and
si-HOIP group when compared to the control group (P<0.05).

Conclusion:

TRAF1 was an important negative regulator of liver transplantation I/R by inhibiting
the activation of NF-κB in KCs and preventing its M1 phenotype transformation.

Authors: Masoumi Seyedeh Zahra , Oshvandi Khodayar , Rostami-Moez Masoumeh , Shayan Arezoo , Kazemi Farideh
Published: January 2021

Background:

Infertility can cause low marital satisfaction. Marital satisfaction has an
important effect on infertile couples’ health.

Objective:

This study aimed to assess the effect of relationship enrichment training on improving the marital satisfaction
of infertile couples.

Methods:

This randomized clinical trial was conducted on 50 infertile couples in the infertility center
of Fatemiyeh Hospital in Hamadan, Iran in 2018. Participants were matched for demographic
characteristics and randomly assigned to intervention and control groups (each group had 25 couples).
Informed consent was obtained from all participants. The Enrich Marital Satisfaction questionnaire
and demographic information were used to collect data before the study and two months
after the intervention. Two trained midwifery students taught only the intervention group about the
relationship enrichment topics in seven sessions (each session = 90 minutes). The data were analyzed
by SPSS Statistics version 21 using analysis of covariance, independent t-test, chi-square, and
Mann–Whitney. The significance level was set at p ≤ 0.05.

Results:

There was no significant difference in demographic and obstetric information between the
two groups (p >0.05). The mean of marital satisfaction in the intervention group significantly increased
among women and men from 151.00 ±28.61 to 154.88 ±22.62 and from 152.56 ±27.33 to
159.24 ±22.14, respectively, (p <0.001). Conversely, the mean of marital satisfaction decreased
among women and men from 158.13 ±13.86 to 146.25 ±19.53 and from 164.25 ±17.00 to 153.17
±27.50 in the control group (p=0.02).

Authors: Raguzzini Anna , Toti Elisabetta , Bernardi Marco , Castellucci Fabio , Cavedon Valentina , Fedullo Anna Lucia , Milanese Chiara , Sciarra Tommaso , Peluso Ilaria
Published: January 2021

Background::

Interleukin (IL)-6, total antioxidant capacity (TAC) and uric acid (UA) increase after exercise in
able-bodied individuals. Wheelchair Basketball Athletes (WBA), having low muscle mass, could be at risk of post-exercise
ketosis.

Objective::

This study aimed to evaluate the post-exercise ketosis, IL-6 and antioxidant response, in WBA of the Italian
National team, after a simulated match.

Methods::

Dietary intakes, Starvation Symptoms Inventory (SSI), percentage of fat mass (FM%) and basal Respiratory
Exchange Ratio (RER) and Basal Energy Expenditure (BEE), were evaluated. Salivary TAC, UA and IL-6 were measured:
before (PreM), at the end (EM) and 20 minutes after (PostM) the match. Capillary glucose and β-hydroxybutyrate (βHB)
were monitored. Percentage of Heart Rate Reserve (%HRR) was measured to evaluate exercise intensity.

Results::

WBA had low carbohydrates (43.5% of daily energy intake (En)) and high fat (36.3% En) intakes. The increase in
UA at PostM correlated with En (0.810, p<0.01) and was inversely related to βHB at EM (-0.719, p<0.05). Furthermore, at
PostM growing IL-6 levels correlated with BEE (0.778, p<0.05) and inversely related to FM% (-0.762, p<0.5) were found,
which in turn was correlated to SSI (0.781, p<0.05). Also βHB PostM correlated with SSI (0.761, p<0.05) but was inversely
related to RER (-0.745, p<0.05) and En (-0.826, p<0.01).

Conclusions::

Our study suggests that some WBA should improve their dietary habit in order to prevent post-exercise
ketosis and ameliorate the endogenous antioxidant response after exercise.
A Comparative Study of Selected Drug Delivery Systems: Key Emphasis on Cocrystallization
Authors: Dutt Braham , Choudhary Manjusha , Budhwar Vikas
Published: January 2021

:

The low solubility of an active pharmaceutical ingredient particularly biopharmaceutics classification system (BCS) Class II drugs leads to a lower dissolution profile, which in result causes a reduction in the overall bioavailability of drugs. Numerous approaches like nanotechnology, solid dispersion technique, micronization techniques, etc were aimed by scientists in the past to resolve this issue, but still not enough to get the desired outcomes.

:

Key focus of this review is the study of the advantages and disadvantages of cocrystallization, nanotechnology and solid dispersions drug delivery techniques and the benefits of using cocrystallization techniques over the above-mentioned techniques.

:

Various parameters including pharmaceutical, pharmacological and toxicological effects related to these mentioned drug delivery systems have been compared. Their advantages and disadvantages have been elaborated.

:

For drug delivery purpose, the cocrystallization process has numerous advantages over nanotechnology and solid dispersions drug delivery techniques discussed in the text. Cocrystallization is a newer technique that can modify the physicochemical and pharmaceutical properties of active pharmaceutical ingredients (API) with low solubility, low stability or sensitivity toward environmental hazards like temperature, moisture or photostability issues. During cocrystallization, the drug and the coformer interact with each other non-covalently in a fixed stoichiometric ratio. The availability of a large number of coformers makes this technique to be favorable for the researchers in designing cocrystals of newer and older API’s.

:

Although solid dispersions and nanotechnology techniques are being utilized to a larger extent, still there are some drawbacks of these techniques like stability, toxicological factors and protection from environmental factors that need to be considered, while the cocrystallization process drastically modifies the various pharmaceutical parameters without altering the pharmacological properties of API’s. Here in this review, we performed a comparative analysis between nanotechnology, solid dispersion and cocrystallization techniques along with the importance of cocrystallization in the modification of drug profile and various applications in the pharmaceutical and allied industry.
The Impact of Adverse Childhood Experiences (ACEs) on Suicidal Ideation and Suicide Attempts in an Inpatient Adolescent Sample
Authors: Benczkowski Tara , Kostoroski Christine , Stabile Mackenzie , Holler Karen
Published: January 2021

Background:

Suicidal ideation (SI) and suicide attempts (SAs) among adolescents are a significant public health concern worldwide. The current study extends previous research by exploring the association between adverse childhood experiences (ACEs) and SI and SAs in a sample of inpatient adolescents as well as identifying specific predictors for increased risk of SI and SAs.

Methods:

Associations between ACE scores and self-reported SI and SAs were explored in a sample of 154 inpatient adolescents via clinical interview and by analyzing the association between cumulative ACE scores and scores on the Suicidal Tendency scale of a larger personality measure. We also tested for independent relationships between 19 ACEs and SI and SAs to determine unique predictors for suicidality.

Results:

One-way ANOVA analyses revealed that those who attempted suicide reported significantly more ACEs compared to those who did not attempt suicide. Witnessing violence in the home, school, or neighborhood and experiences of discrimination increased one’s likelihood to attempt suicide by two to threefold, while sexual abuse, neglect, and physical abuse increased this likelihood by three-to-fourfold. Stepwise linear regression analyses demonstrated that emotional abuse, living with someone who had mental health problems or attempted suicide were most associated with elevated Suicidal Tendency scores on a personality measure.

Conclusions:

Early identification, education and intervention are imperative to limit or eliminate ACEs from occurring. The impact of cumulative as well as specific ACEs on suicide risk should be closely considered as areas for such intervention. Areas for future research include extending to include more diverse populations such as the LGBTQ community as well as more ethnically and racially diverse populations.

In recent decades, nanoscience and nanotechnology have played a revolutionary role in
the therapeutic domain. Manipulation of atoms and molecules at the nanometric scale endows biomaterials
with specific physicochemical properties. Skin being the largest organ of the human body
and an extensively exploited route for drug delivery, is one of the primary sites for exposure to
nanoparticulate matter. Skin care products and cosmetics also constitute a major source of exposure
to metallic nanoparticles. Metallic nanoparticles are widely used for therapeutic, diagnostic
and cosmetic purposes. The potential risks associated with their use in modern medicine are a subject
of extensive research. The present article aims to discuss the toxicity concerns associated with
the use of metallic nanoparticles in dermatological products, and provide an overview of their in
vitro and in vivo methods of nanotoxicity assessment, as per OECD guidelines. It also presents a
concise account of the lacunae in the existing guideline, which need to be addressed in order to
adapt the prescribed tests to the testing of nanoparticles. The review also gives an insight into the
gaps in the in vitro, in vivo correlation of data furnished by various research groups. It provides a
glimpse of important regulatory aspects applicable to the evaluation of topically applied nanoparticulate
systems. In the end, it discusses the challenges and future perspectives in order to strengthen
the scientific investigations in this domain.

PENERAPAN DOUBLY-FED INDUCTION GENERATOR (DFIG) UNTUK PEMBANGKIT LISTRIK TENAGA ANGIN
Authors: Arindya Radita
Published: January 2021

Wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so using the RSC. However, within the available current capacity the GSC can be controlled to participate in reactive power generation in steady state as well as during low voltage periods. The GSC can supply the required reactive current very quickly while the RSC passes the current through the machine resulting in a delay. Both converters can be temporarily overloaded, so the DFIG is able to provide a considerable contribution to grid voltage support during short circuit periods. This report deals with the introduction of DFIG, AC/DC/AC converter control and finally the SIMULINK/MATLAB simulation for isolated Induction generator as well as for grid connected Doubly Fed Induction Generator and corresponding results and waveforms are displayed.

ABSTRACTThe blackboard is one of the facilities that is still widely used in the learning process in Indonesia. This is because most educational methods have not been fully touched by digital technology, especially in remote areas. In deleting the writings on the board, it takes time, even more draining. We need to know that removing the blackboard is an activity that is not liked by students because it must be done repeatedly. To overcome this problem, one solution that can be done is to make an automatic eraser tool. This whiteboard eraser is based on a sound sensor. The working process is through the voice commands given, the Smart Assistant is designed to make it easier for us to delete the writing on the board. The design of the Smart Assistant is more effective where the program uses a sound sensor system with the Voice Recognation method, so that when we want to erase the whiteboard we just have to sound according to the commands we have programmed on the Arduino Software so the whiteboard will be deleted.ABSTRAKPapan tulis merupakan salah satu sarana yang masih banyak digunakan dalam proses pembelajaran di indonesia. Hal ini dikarenakan sebagian besar metode pendidikan belum sepenuhnya tersentuh teknologi digital terkhusus daerah-daerah terpencil. Dalam menghapus tulisan-tulisan di papan tulis membutuhkan waktu terlebih lagi menguras tenaga. Perlu kita ketahui bahwa menghapus papan tulis merupakan aktivitas yang tidak disenangi oleh para siswa karena harus dilakukan berulang-ulang. Mengatasi masalah ini, salah satu solusi yang bisa dilakukan adalah membuat sebuah alat penghapus otomatis. Penghapus papan tulis ini berbasis sensor suara. Penelitian ini menggunakan jenis penelitian R&D dengan metode waterfall. Proses kerjanya yaitu melalui perintah suara yang diberikan maka Smart Assistant ini dirancang untuk memudahkan kita dalam menghapus tulisan pada papan tulis. Perancangan Smart Assistant ini lebih efektif dimana program ini menggunakan sistem sensor suara dengan metode Voice Recognation, sehingga saat kita ingin menghapus papan tulis cukup dengan kita bersuara sesuai dengan perintah yang telah kita program pada software arduino dengan begitu papan tulis akan dihapus oleh alat tersebut.
