Volatilities in the interdependence between stock market, bond market, and foreign exchange market in Vietnam: An empirical investigation
Authors: Nguyen Khac Quoc Bao , Bui Van Hoang
Published: October 2020

This study analyzes volatilities in the relations between stock mar-ket, bond market, and foreign exchange market in Vietnam from April 2014 through December 2015. Particularly, we address the questions of whether there exist sudden changes in correlations be-tween the markets to respond to volatility shocks and whether these changes are temporary or extended. By using VAR(p) – FIEGARCH(1,d,1) – cDCC and PELT approaches in combination with a regression estimation with dummy variables, our empirical results validate the interdependence between the markets, which is found to vary over time. More importantly, volatility shocks give rise to sudden changes in their correlations, and at certain times these are long-lasting. Investors and policy makers in Vietnam should accordingly have due consideration of long-term spillovers.
Determinants of capital structure of listed firms in Vietnam: A quantile regression approach
Authors: Nguyen Thi Canh , Nguyen Thanh Liem , Tran Hung Son
Published: October 2020

This study empirically examines the link between firm characteristics and leverage using the data of Vietnamese non-financial listed firms from 2006 to 2015. In addition to traditional panel data methods, we employ a conditional quantile regression that unveils the behavior of regressors throughout the leverage distribution. The results confirm the non-linear relationship between firm characteristics and leverage at different levels of debt.
Tax revenue, expenditure, and economic growth: An analysis of long-run relationships
Authors: Nguyen Phuong Lien , Su Dinh Thanh
Published: October 2020

Focusing on the investigation of “long-term” relationship between tax revenue, expenditure, and economic growth, this paper employs the Granger causality test and finds that the linkage between tax revenue and spending is a bi-directional causal correlation. Furthermore, applying Persyn and Westerlund’s (2008) co-integration test allows for corroboration of existence of long-run cointegration linkages among outcome of economy and the three variables. In addition, by adopting two-step system generalized method of moments (SGMM) for a dynamic panel of 82 developed and developing countries during 16-year period (2000–2015), this research demonstrates that the impact of tax revenue and spending is substantial and ambiguous, depending on different groups of economies.
Determinants of Vietnam’s outward direct investment: The case of Cambodia
Authors: Võ Thanh Thu , Lê Quang Huy , Lê Thị Bích Diệp
Published: October 2020

This research focuses on the determinants of Vietnam’s outward FDI by studying simultaneously the influence of two pull factors and push factors. In addition, the work examines the differences in assessing the impact of two factors groups on investment decisions by market entry method. The authors conduct qualitative research interviewing six experts as the managers have an important role in the decision to invest directly abroad for their business and quantitative research by multiple regression methods studying samples consisting of 248 enterprises. Push factors group from Vietnam includes competitive pressure of Vietnam market, monetary policy, interest rates of Vietnam, regulations and procedures for licensing investment abroad of Vietnam, incentive policy, and investment incentives to overseas. Pull factors group from host country includes culture–geography, macroeconomics and market, infrastructure, regulations and policies related to investment. Through two groups of factors, the authors withdraw into four groups that impact the Vietnam’s FDI abroad including: (i) culture–geography, (ii) infrastructure; (iii) the macro-economic and market; and (iv) regulations and policies related to investment. The results indicate that two groups of factors, both pull factors and push factors, have impact on Vietnam’s FDI abroad.
Supply chain management: Solutions to improving the competitive advantage of small- and medium-sized enterprises: The case of Danang City
Authors: Lê Thị Minh Hằng
Published: October 2020

Supply chain management (SCM) has been proven to improve the competitive advantage, and increase the effectiveness of operation in small and medium sized enterprises (SMEs) (Chin et al., 2012). This study investigates the measurement of SCM practice in Vietnam with the sample of 148 SMEs in Danang. The research findings exhibit the humble degree of SCM practices within these firms. These activities are in the primary form of SCM practice as supplier’s quality management, customer interaction, and customer satisfaction measurement. The findings also indicate the limitations in practicing SCM in Danang SMEs, and propose implications in policy adjustment to promote SCM practices and advance the competitive advantages of SMEs.
Inflation and the public investment: Growth relationship in Vietnam
Authors: Nguyen Van Bon
Published: October 2020

Public capital spending positively contributes to economic growth and development in many countries worldwide. However, questions concerning the importance of inflation in the public investment–growth relationship are of great interest. This study examines the role of inflation in the public investment–growth relationship in Vietnam using the two-step GMM Arellano-Bond estimators for a balanced panel data of 52 provinces during the period of 2005–2014. More interesting are the empirical findings. First, inflation significantly increases the volume of public capital spending. Second, public investment and inflation enhance economic growth, but their interaction term impedes it. Third, private investment, government recurrent expenditure, and trade openness are the significant determinants of growth. These findings suggest some important policy implications related to public capital spending and inflation in developing countries, specifically the Vietnam government.
Factors affecting net interest margin of joint-stock commercial banks in Vietnam
Authors: Pham Hoang An , Vo Thi Kim Loan
Published: October 2020

This study analyzes factors affecting net interest margin of joint-stock commercial banks in Vietnam. The paper uses the secondary data of 26 banks with 182 observations for the period of 2008–2014 and applies the panel data regression method. The empirical results indicate that lending scale, credit risk, capitalization, and in-terest rate have positive impacts on net interest margin. In contrast, managerial efficiency has a negative effect on net interest margin. However, bank size and loan to deposit ratio are statistically insig-nificant to net interest margin.

The Variation of the Salt Concentration at the Discharge of a River into a Saline Water
Authors: Juncu Gheorghe , Nicola Aurelian , Curcă Elena Stroilă
Published: October 2020

A plume model is used to describe the variation of the salt concentration at the discharge of a river into a saline water. The integral model of the plume behavior consists of a set of ordinary differential equations derived from conservation of mass, momentum and salt concentration. The temperatures of the plume and ambient saline water are considered equal. The concentration of the salt in the river water is null. The saline water is assumed motionless. After release from the river, the concentration of the salt in the plume increases by mixing with the ambient saline water. The rate of mixing depends upon the local plume and ambient fluid properties such as velocity and salt concentration.

Published: October 2020

Let R be a commutative ring and M an R-module. In this article, we introduce the concept of S-2-absorbing submodule. Suppose that S ⊆ R is a multiplicatively closed subset of R. A submodule P of M with (P :
R M) ∩ S = ∅ is said to be an S-2-absorbing submodule if there exists an element s ∈ S and whenever abm ∈ P for some a, b ∈ R and m ∈ M, then sab ∈ (P :
R M) or sam ∈ P or sbm ∈ P. Many examples, characterizations and properties of S-2-absorbing submodules are given. Moreover, we use them to characterize von Neumann regular modules in the sense [9].

Published: October 2020

Background. Conflicts across professional workgroup and hierarchies inundate the clinical workplace. Early Career Doctors (ECDs) are also affected either as victims or as a provocateur/perpetrator. The effects of conflict at their workplaces have both significant positive and negative dimensions and impacts on ECDs. Little has been reported about conflict among ECDs in Nigeria.

Thus, this study explored the issue of conflict and conflict resolution among ECDs in Nigeria, in a bid to elicit information on the causes, consequences, perpetrators and victims.

Method. This was a qualitative study, using Focus Group Discussions (FGD) to explore information on conflict and conflict management among purposively selected key respondents (n = 14) from seven tertiary hospitals in Nigeria. The respondents are ECDs who were leaders and representatives of other ECDs in their various hospitals. Two FGDs were conducted.

Results. The result showed that conflict is inescapable in clinical settings and occurred at different levels. The perpetrators are varieties of health workers, and most are task-related conflicts, although there are relational ones. The conflicts with the government on labour-related issues are also frequent. The lack of job description and specification and power struggle among others were highlighted as the drivers of conflicts between ECDs and other health-workers. Conclusion. The findings of the study were discussed, and suggestions were made to reduce its effect, which would require structural solutions to mitigate at different levels and the diverse players in the health sectors.
Using a game engine to visualize the Main Building of the Warsaw University of Technology in a mobile application
Authors: Marciniak Jacek Bernard , Janicki Hubert
Published: October 2020

The aim of the study presented in this article is to identify and analyse the problems which arise when creating a 3D model based on two-dimensional data and its import into a game engine and then developing algorithms to automate this process. The authors decided that they would use the Unity game engine to create an application presenting the results of modelling the interior of the Main Building of the Warsaw University of Technology. The work was divided into stages in which problems related to the adopted method were identified and the automation of selected activities was suggested. The main tasks performed during the study included processing the source data into a 3D model along with the correction of errors made during this process, detailing the model by adding characteristic elements of the building’s interior, and creating the so-called game scene in the Unity game engine along with the implementation of the application’s behaviour. The developed software can be integrated with indoor navigation systems, and the implemented scripts can be used during the preparation of other models.
COVID-19 – as a global problem of public health
Authors: Drop Bartłomiej , Janiszewska Mariola , Drop Katarzyna
Published: October 2020

Encounter of the globalized world with the pandemic of new coronavirus SARS-CoV-2 presents humanity of almost all countries in an unprecedented, dangerous situation. The new coronavirus is responsible for COVID-19 disease, which is currently the most important, international problem of public health. In the period from 31st December, 2019 to 12th April, 2020 as many as 1 734 913 COVID-19 cases were reported in the world, including 108 192 deaths. In Poland 6674 cases were reported, including 232 deaths.

The coronavirus pandemic is not still under control, neither in the world nor in Europe, and chances for the disappearance of the problem during the next few months are small. The most important in counteraction of the virus transmission are prevention and control of epidemic. The necessary social distance should be maintained, protective masks should be worn and hand-hygiene procedures should be respected. Fast, reliable diagnostics, proper way of procedure in the case of infection, isolation rules implementation and, in the future, protective vaccinations are of a key importance in reduction of virus transmission in the population.

At the same time, together with the COVID-19 pandemic emergence, collapse of the globalization rules may be observed, which manifests in closing borders, avoiding traveling, depending of competing countries on each other in the range of necessary medications or other critical resources. The emergence of the second wave of disease is probable, especially in the case of too early abolition of restrictions preventing virus transmission. Apart from reducing the SARS-CoV-2 pandemic, efforts should be made to elaborate complex measures preventing future epidemics of animal origin.
Crisis within a crisis. Psychological dimension of the pandemic
Authors: Markiewicz Renata
Published: October 2020

The COVID-19 pandemic caused chaos in many countries. The reason of that were mostly lack of knowledge concerning the disease, fear of infection, difficulties in defining its consequences. A reasonable action in fighting the epidemic turned out to be social isolation and suspension of all state institutions. While at the beginning of introduction of those actions the society accepted the restrictions with understanding, the prolonging state of isolation caused in some people increased anxiety, fear and concerns about the future. Reduction of a negative effect of pandemic can be a problem for a long time, especially when we will not be able to adequately interpret a danger, comprehend it and appropriately react.

We further discuss the upper limit on the number of clues in a crossword puzzle with no 2-letter answers, and open questions are given. As a bonus, a mathematically-themed crossword puzzle is included!
Next Level Odd-One-Out Puzzles
Authors: Berger Benjamin
Published: October 2020

A commonly occurring task in intelligence tests or recreational riddles is to “find the odd one out”, that is, to determine a unique element of a set of objects that is somehow special. It is somewhat arbitrary what exactly the relevant feature is that makes one object different. But once that is settled, the answer becomes obvious. Not so with a puzzle popularized by Tanya Khovanova to express her dislike for this type of puzzle. Here, it is a more complicated relation between the objects and the features that determines the odd object, because there is only one object that does not have a unique feature expression. This puzzle inspired me to look for even more complicated relations between objects, features and feature expressions that appear to be even more symmetric, but actually still single out a “special object”. This paper provides useful definitions, a theoretical basis, solution algorithms, and several examples for this kind of puzzle.

The Projected Past: Why Were Translated Certain Historical Novels?
Authors: Engelbrecht Wilken
Published: October 2020

The 140 years between 1850 and 1990 cover an important period from the beginning of modern literature and modern publishing houses in the second half of the nineteenth century till the end of the Communist regime. Over this period some 450 Dutch and Flemish literary works were translated into Czech and some 75 into Slovak. Historical novels and novellas make up a good part of them.

As Connor (2015) has clearly shown, historical novels were a popular genre in Communist times for ideological reasons. They were considered “excellent educational instruments for people not yet apt to understand heavier work like the Communist Manifesto” as the young translator Olga Krijtová wrote to the Communist Dutch writer Theun de Vries in the early 1950s. Reviews, editor’s reports and editorial statements indicate, however, that historical novels had a similar function already before Communism, from the beginnings of Czech and Slovak translation of Dutch written literature.

In this paper, we will discuss several historical novels in Czech translation by Hendrik Conscience, Louis Couperus, Madelon Székely-Lulofs, Theun de Vries, and Harry Mulisch – to illustrate changing ideological views.
O direito ao esquecimento como concretização dos direitos da personalidade em face à liberdade de expressão
Authors: Siqueira Andressa de Bittencourt
Published: October 2020

Tendo como premissa que a personalidade se adequa às novas formas de seu exercício no evoluir dos tempos, emerge a questão do direito ao esquecimento, não raro atrelada ao desenvolvimento das tecnologias. Nesse panorama, surge o seguinte problema de pesquisa: de que forma o então chamado direito ao esquecimento traça seus contornos na sociedade atual, com pano de fundo na sociedade e no ordenamento jurídico brasileiros? Para analisar o problema, parte-se do método de abordagem dedutivo para que o aqui exposto possa ser aplicado em casos concretos, enquanto que o método de interpretação centra-se no sistemático-teleológico, porquanto considera-se o ordenamento jurídico como um conjunto de normas organizadas a satisfazer determinados fins. Como técnica de pesquisa, analisa-se o corpo doutrinário, brasileiro e estrangeiro, bem como o arcabouço legislativo, além dos preceitos constitucionais e da jurisprudência brasileira, sem excluir-se da apreciação outras decisões, a fim de ilustrar-se melhor o problema. Por fim, aponta-se que o direito ao esquecimento está centrado dentro dos direitos da personalidade, como uma das mais variadas formas as quais esta possa ser concretizada, resultando e emergindo a partir da colisão da proteção da personalidade com a liberdade de expressão. Não se trata, portanto, de um novo direito, mas, sim, de uma nova maneira de resguardar a personalidade de um indivíduo.

O tema assume evidência quando das decisões dos Tribunais brasileiros acerca do assunto, tão novo e de muita discussão atualmente. A consequência do tema referido neste trabalho, foi a delonga do direito pátrio em se colocar a par de um assunto que afeta e traz implicações na vida privada das pessoas.
Crimes de sonegação fiscal e o mandado constitucional de criminalização
Authors: Correra Marcelo Carita
Published: October 2020

O presente trabalho busca estudar os crimes de sonegação fiscal em face da Constituição Federal. Foi analisada a existência de mandados constitucionais de criminalização e sua aplicação em face dos crimes de sonegação fiscal. Foi necessário recorrer a conceitos de economia e finanças públicas, especialmente no que tange ao déficit das contas públicas e a inflação decorrente da dominância fiscal. Ao final, determinou-se que, diante da Constituição, há mandado de criminalização implícito que suporta os crimes de sonegação fiscal. Neste contexto, determinou-se que a Lei 10.684/2003, ao estabelecer causa de extinção da punibilidade diante do pagamento do valor devido, violou texto magno. Logo, reputou-se o referido dispositivo inconstitucional. Houve, ainda, a demonstração dos efeitos deletérios do déficit público para o controle da inflação, o que gera prejuízos para toda a sociedade e, dessa forma, legitima a determinação constitucional para utilização do direito penal como garantia do equilíbrio fiscal.

The article considers the organization of urban and rural space in terms of their friendliness towards children and adolescents. The spatial characteristics of places, their assessment is studied in line with a new interdisciplinary direction - the geography of childhood, formed at the intersection of humanitarian geography and social studies of childhood. To collect empirical data, an essay method was chosen that provides children with the opportunity to describe their favorite place in the city. In total, 140 compositions were collected by schoolchildren aged 9–17 from the cities of Komsomolsk-on-Amur, Astrakhan, Kaliningrad, Moscow, St. Petersburg, Cheremkhovo and the village of Dolgorukovo. The presented locations differ in their size, remoteness from the European part of Russia and the socio-economic opportunities for organizing space for children. Through geographical essays of children, which described their favorite places, the problems of studying the territory of residence in terms of spatial, socio-economic and subjective characteristics were solved.

Published: October 2020

The article is devoted to the Constitution of Brazil of 1824, the first in the history of this country. The political structure of the Brazilian Empire described in the article was based on this Constitution, which was in force from its adoption until the proclamation of the First Brazilian Republic (1889). The article analyzes the tasks that stood at the creation of the Constitution and the main changes made to the state structure of Brazil after the law was initiated. It is emphasized that, although the Imperial Constitution did not solve all the problems in Brazilian society, it was the first to identify the issues to be resolved, and that the monarchy lasted longer in Brazil than successive Republican and dictatorial regimes, including thanks to the basic law of the country in the edition of 1824.
Conflict of the Khabarovsk City Duma and the Provisional Government of the Far East in 1920
Authors: Popov F. А.
Published: October 2020

The article analyzes the confrontation between the Khabarovsk city government of the "Kolchak convocation" and the regional government of Primorye formed as a result of the anti-Kolchak coup on January 31, 1920. The parallel existence of several state formations in the Far East created the ground for political instability. The conflict between the Khabarovsk Duma and the Vladivostok government was complicated by an ideological factor: most Duma members belonged to the right, anti-communist camp, while the regional government consisted mainly of socialists. The refusal of both sides to compromise resulted in the unilateral declaration of "independence" of Khabarovsk in August 1920. The evacuation of Japanese troops and the lack of support for the actions of the Duma among the townspeople led to the "separatists" to failure. The conflict was seized by the rivals of Primorye in the unification of the Far East – the Far Eastern Republic and the Soviet Amur Region – the latter's troops, contrary to the protest of the Vladivostok government, occupied Khabarovsk in October 1920.

A Review: Protein Identification by LC-MS: Principles, Instrumentation, and Applications
Authors: Alhendi Abeer Salh
Published: October 2020

This review will focus on protein and peptide separation studies of the period 1995 to 2010. Peptide and protein analysis have developed dramatically after applying mass spectrometry (MS) technology and other related techniques, such as two-dimensional liquid chromatography and two-dimensional gel electrophoresis. Mass spectrometry involves measurements of mass-to-charge ratios of the ionized sample. High-performance liquid chromatography (HPLC) is an important technique that is usually applied before MS is conducted due to its efficient separation. Characterization of proteins provides a foundation for the fundamental understanding of biology aspects. In this review, instrumentation, principle, applications, developments, and accuracy of the measurements of mass spectrometry will be reviewed and discussed. In addition, the principles of HPLC technology will be explained, which is necessary before applying MS.
A Practical Method to Calculate and Model the Petrophysical Properties of Reservoir Rock Using Petrel Software: A case Study from Iraq
Authors: Wali Sarah Taboor , Baqer Hussain Ali
Published: October 2020

Nasiriyah oilfield is located in the southern part of Iraq. It represents one of the promising oilfields. Mishrif Formation is considered as the main oil-bearing carbonate reservoir in Nasiriyah oilfield, containing heavy oil (API 25o(. The study aimed to calculate and model the petrophysical properties and build a three dimensional geological model for Mishrif Formation, thus estimating the oil reserve accurately and detecting the optimum locations for hydrocarbon production.

Fourteen vertical oil wells were adopted for constructing the structural and petrophysical models. The available well logs data, including density, neutron, sonic, gamma ray, self-potential, caliper and resistivity logs were used to calculate the petrophysical properties. The interpretations and environmental corrections of these logs were performed by applying Techlog 2015 software. According to the petrophysical properties analysis, Mishrif Formation was divided into five units (Mishrif Top, MA, shale bed, MB1 and MB2).    A three-dimensional geological model, which represents an entrance for the simulation process to predict reservoir behavior under different hydrocarbon recovery scenarios, was carried out by employing Petrel 2016 software. Models for reservoir characteristics (porosity, permeability, net to gross NTG and water saturation) were created using the algorithm of Sequential Gaussian Simulation (SGS), while the variogram analysis was utilized as an aid to distribute petrophysical properties among the wells.

     The process showed that the main reservoir unit of Mishrif Formation is MB1 with a high average porosity of 20.88% and a low average water saturation of 16.9%. MB2 unit has good reservoir properties characterized by a high average water saturation of 96.25%, while MA was interpreted as a water-bearing unit. The impermeable shale bed unit is intercalated between MA and MB1 units with a thickness of 5-18 m, whereas Mishrif top was interpreted as a cap unit. The study outcomes demonstrated that the distribution accuracy of the petrophysical properties has a significant impact on the constructed geological model which provided a better understanding of the study areaâ€™s geological construction. Thus, the estimated reserve h was calculated to be about 7945 MSTB. This can support future reservoir development plans and performance predictions.

Published: October 2020

In this paper, we propose an Interleave-Division Multiple Access (IDMA) based uplink multi-user system fornext generation WLAN. By minimizing the latency throughaccurate detection per iteration, we were able to design a receiver architecture that meets the latency demands of current IEEE802.11 WLAN. To do this, the proposed system utilizes a novel algorithm for simplified LLR calculation of the soft input soft output demapper needed in the IDMA first stage detection.The proposed system has a maximum of 34.8 bits/s/Hz spectral efficiency for a single spatial stream and can support up to 8 users in a single 20MHz channel. We compare the proposed system to a reference OFDMA system and show its advantages in terms of diversity, flexibility and BER performance.

The architecture of Towani Tolotang’s traditional house has characteristics that represents the identity, activities, social and cultural values ​​of the community. The Towani Tolotang people strongly maintain the relationship of togetherness and unity shown by the architecture of traditional houses. This study discussed and examined the characteristics of micro spatial patterns, functions, and meanings of the Towani Tolotang’s traditional house. The study was conducted in Amparita Village, Sidrap Regency, South Sulawesi. The discussion on the architecture of the traditional house of Towani Tolotang was carried out by applying the naturalistic phenomenological method. This type of research is qualitative with the process of collecting data through participatory observation, in-depth interviews, and document studies. Data analysis was performed using descriptive qualitative, describing in accordance with the natural situation. The results of the study revealed that there were two spaces in the spatial pattern of Towani Tolotang’s traditional house being the characteristics different from Bugis’s houses in general. They were tamping and special rooms. The function of the space was similar to the Bugis’s house in general, except the two spaces. Tamping was functioned as a place to receive guests with the status of ordinary people, and the special room was used as a place for ritual and taking prayer for the people of Towani Tolotang. Every space in the Towani Tolotang’s traditional house has its own meaning, included tamping which means respect for the traditional leader and special room which means the sacred space.

Urinary bladder cancer and its associated factors – An epidemiological overview
Authors: Mishra Varsha , Balasubramaniam Ganesh
Published: October 2020

As per the GLOBOCAN 2018, bladder cancer was estimated to have 549,000 new cases and 200,000 deaths per year and was ranked 10th among all cancers in the world; it contributed 3.4% to the total cancer burden worldwide. In India, there were 18,921 new cases and 10,231 deaths with an incidence rate (per 105) of 2.4 and 0.7 in males and females, respectively, and mortality rates (per 105) as 1.3 and 0.3 in males and females, respectively; it is ranked 17th in incidence and 19th in mortality. The aim of the study is to report incidence rates, mortality rates, and risk factors for bladder cancer with special emphasis to Indian data. It is hypothesized that bladder cancer is likely to increase due to changing lifestyle and environmental factors that would directly impact on the disease burden. This review study on bladder cancer (ICD: C67) is based on various reports and studies published. Incidence and mortality rates are obtained from GLOBOCAN-2018, Cancer Incidence in Five Continents (CI5-XI), and Indian Council of Medical Research publication on Indian Cancer Registry database. There are case–control studies reported in literature that elucidates on risk factors that include age, gender, tobacco consumption, arsenic and nitrate in drinking water, exposure to potential carcinogens at workplace, and family history. Urinary bladder cancer has a wide spectrum of severity from the indolent low grade non-muscle invasive disease to muscle invasive disease which has poor outcomes despite treatment. There seems to be an increasing trend of this cancer in the developing countries, including India. More studies are required to be undertaken to understand this disease, with the underlining importance of public awareness. The review aims to provide some leads to formulate policies for cancer control strategies based on past findings from the literature.

Objectives:

The world is grappling with an ongoing COVID-19 pandemic that has shaken the mankind to the core and disrupted the lives of everyone. The aim of the study was to assess the presence of psychological distress, depression, anxiety, stress, and insomnia experienced by the Indian healthcare workers.

Material and Methods:

A cross-sectional study was conducted in India among 777 doctors to evaluate the mental health of doctors working in Corona wards from April 2020 to May 2020 using a pre-designed, pre-tested validated, semi-structured DASS-21 questionnaire, and the Insomnia Severity Index. Continuous variables between the groups were measured using the Mann–Whitney U-test and the Kruskal–Wallis H test.

Results:

Among the doctors working for the pandemic, around 55% of medical officers in the study reported having moderate levels of depression. With respect to anxiety, it was found that among men as many as 52% reported experiencing severe anxiety and 24% had moderate levels of anxiety whereas females reported as high as 68% and 48% of moderate and severe anxiety, respectively. In our study, around 30% and 44% of male doctors reported mild and moderate levels of stress, respectively, whereas 70% and 56% of female doctors reported mild and moderate levels of stress, respectively. It was also observed that among female doctors the rates of moderate insomnia were especially high (65%), whereas a high level of male participants reported sub-threshold insomnia (52%).

Conclusion:

Early screening targeting the medical workforce and the implementation of psychological interventions is essential for protecting and maintaining the functionality of the health-care system.
Leprosy vaccines – A voyage unfinished
Authors: Ali Lasida
Published: October 2020

Leprosy, a chronic granulomatous disease caused by Mycobacterium leprae, is endemic in many regions of the world. With introduction of multidrug therapy in 1982, there has been a dramatic reduction in the prevalence of leprosy, but new cases continue to appear. There have been more than 200,000 new cases per year for the past 10 years. There is a renewed interest in leprosy vaccines with immunoprophylactic and immunotherapeutic roles. Due to the difficulty in cultivating M. leprae in artificial media, vaccine strategies have centered on the use of cross-sensitizing mycobacteria. Bacillus Calmette–Guerin (BCG) has been the most popular among these, but with a widely varying protective efficacy reported from different parts of the world. In three meta-analyses, BCG has shown strong evidence of efficacy against leprosy. Recently, India has focused interest on another vaccine, Mycobacterium indicus pranii vaccine earlier known as Mycobacterium w. To overcome the limitations of these whole cell vaccines, various recombinant BCGs and subunit vaccines have been developed and studied in experimental models. These often yield inconsistent results. However, a new subunit recombinant vaccine – LepVax holds promise and has completed Phase 1a clinical trials successfully.
"Frau Klara Schumann der besten Sängerin."
Authors: Borchard Beatrix
Published: October 2020

It is well known that Clara Schumann was educated by her father Friedrich Wieck who published his pedagogical essay Clavier und Gesang in 1853. What is less known is that Clara Schumann was not only trained as a pianist, but also as a singer. Furthermore, she had a deep affinity to singers throughout her life. Her own singing competence, her singendes Spiel and the dialogue between Clavier und Gesang – piano and song – which characterized her programme, is also reflected in the piano arrangements of Clara Schumann’s songs.
