Published: August 2021

BackgroundThe Coronavirus disease (COVID-19) outbreak in 2019, has shocked the entire world. As an effort to control the disease spread, the Indian government declared a nationwide lockdown on March 25th, 2020. As dental treatment was considered high risk in the spread of COVID-19, dentistry became one of the most vulnerable professions during this time. Dental professionals had to face job layoffs, salary cuts in professional colleges, closure of private clinics resulting in huge psychological, moral, and financial crises. Studies during the previous and present pandemics have shown mental issues among health care workers necessitating institutional reforms, along with early care and support. A balance in the work-life amongst professionals is the key to better efficiency and, was majorly affected during the COVID-19 pandemic lockdown due to sudden unexpected changes. Hence this study was conducted to understand the changes they underwent both at home and professional front with a hypothesis that physical and mental health, activities, relationship status, and workplace influence the work-life balance.MethodsA pre-validated questionnaire survey was done on dentists across India. Structural Equation Modelling and path analysis were applied to the data collected.ResultsThe results of the study supported the hypothesis that factors like physical and mental health, activities, relationship status, and workplace influenced the work-life balance directly. A significant imbalance was seen amongst the female dentists.ConclusionThe present study proved the unpreparedness among dental professionals. Hence an evolutionary phase in every field with better working protocols, robust mental health support, and a focus on strategies to face future such emergencies is required.

O objetivo do trabalho foi examinar a correspondência dos focos do mosquito Aedes aegypti com dados de altitude e declividade do ambiente citadino de Montes Claros-MG. A partir dos resultados, o assunto poderá contribuir nessa temática necessária, a respeito da qualidade urbana e a geografia da saúde social. Os resultados mostraram um coeficiente de determinação (R²) final igual a 0,973 - o que denotou alto poder preditivo para a combinação das variáveis independentes trabalhadas. O Índice Breteau de 2016 foi aquele com maior peso explicativo (p < 0,01) entre o conjunto de dados para a explicação da infestação larvária ocorrida em 2017. Foi verificado que a altitude média foi significativa nessa associação (p < 0,05), e apresentou correlação negativa conforme o coeficiente parcial de regressão (-6,460 e t = -2,157). Em segundo plano, a altitude máxima foi significativa (p < 0,08). Chegou-se a conclusão de que, numa relação do período anterior com o seguinte, nas áreas de maior incidência larvária, quanto mais baixa é a altitude, maior é a infestação pelo mosquito.
Bissu on Contesting Indigeneity with Islamic Puritanism in the Sacred Arena

Published: August 2021

The presence of Islam in the Bugis Bone tribe not only changes people's beliefs but also traditional activities such as wedding rituals, mappalili (traditional ceremonies before planting rice), guarding arajang (heirlooms). The positions of Bissu, who is an indigenous leader, are very influential in the Bugis Bone community, but nowadays, its existence is discredited by the presence of Islamic hegemony. This research focuses on the transformation of the perseverance of Bissu in the leadership of traditional rituals in the Bugis Bone Tribe, before and after interacting with Islamic religious values. This study uses a descriptive method that describes the social conditions in the life of Bissu, by observation and interview techniques to the Bissu, Muslim leaders, and cultural actor. This study found the fact that the existence of Islam had a dominant influence on the social status of Bissu, which resulted in their role as leaders of traditional rituals being less respected by the community. The role of Bissu in daily activities has become less involved because it has been replaced by the values of religious puritanism. The government needs to educate the history of Bissu and the cultural traditions of Bone to the public and young generation.

Stepwise Markov model: a good method for forecasting mechanical ventilator crisis in COVID-19 pandemic
Authors: Olmos Pablo R. , Borzone Gisella R. 
Published: August 2021

AbstractObjectivesOne important variable influencing day-to-day decisions in COVID-19 pandemic has been an impending shortage of mechanical ventilators due to the large number of people that become infected with the virus due to its high contagiousness. We developed a stepwise Markov model (a) to make a short-term prediction of the number of patients on ventilator, and (b) to determine a possible date for a ventilator crisis.MethodsStarting with the exponential curve of new cases in the previous 14 days, we calculated a Markov model every 5 days thereafter, resulting in a daily estimate of patients on ventilator for the following 25 days, which we compared with the daily number of devices in use to predict a date for ventilator crisis.ResultsDuring the modeled period, the observed and predicted Markov curves of patients on ventilator were very similar, a finding confirmed by both linear regression (r=0.984; p<0.0001) and the near coincidence with the identity line. Our model estimated ventilator shortage in Chile for June 1st, if the number of devices had remained stable. However, the crisis did not occur due to acquisition of new ventilators by the Ministry of Health.ConclusionsIn Chile as in many other countries experiencing several asynchronous local peaks of COVID-19, the stepwise Markov model could become a useful tool for predicting the date of mechanical ventilator crisis. We propose that our model could help health authorities to: (a) establish a better ventilator distribution strategy and (b) be ready to reinstate restrictions only when necessary so as not to paralyze the economy as much.
Study on the effect of microwave roasting pretreatment on nickel extraction from nickel-containing residue using sulfuric acid

Published: August 2021

Abstract
Various means have been proposed to solve problems such as high ash content and complex composition in the recycling of nickel-containing residue produced by battery manufacturing enterprises. Microwave roasting pretreatment is proposed to improve the nickel leaching rate from the residue. The effect of different experimental conditions like microwave roasting temperatures, roasting times, and microwave powers on the nickel leaching rate was studied. It was found that the effect of roasting temperature on the nickel leaching rate was more significant than those of roasting time and microwave power. Meanwhile, after microwave roasting pretreatment, the rate of nickel leaching from the residue could be increased by 20.43%, and weight of the material could also be reduced by more than 21%. After microwave roasting at 450°C, there was no significant change in the main phases of the material, but the surface of the particles exhibited an apparent stratified dissociation phenomenon. Response surface methodology (RSM) was used to optimize the parameters of microwave roasting with nickel leaching rate as the response value. The results showed that the nickel leaching rate could reach 93.11% for roasting at the microwave power of 962 W for 6.2 min under the temperature of 452°C.
A robust hazard ratio for general modeling of survival-times
Authors: Martínez-Camblor Pablo , MacKenzie Todd A. , O’Malley A. James 
Published: August 2021

Abstract
Hazard ratios (HR) associated with the well-known proportional hazard Cox regression models are routinely used for measuring the impact of one factor of interest on a time-to-event outcome. However, if the underlying real model does not fit with the theoretical requirements, the interpretation of those HRs is not clear. We propose a new index, gHR, which generalizes the HR beyond the underlying survival model. We consider the case in which the study factor is a binary variable and we are interested in both the unadjusted and adjusted effect of this factor on a time-to-event variable, potentially, observed in a right-censored scenario. We propose non-parametric estimations for unadjusted gHR and semi-parametric regression-induced techniques for the adjusted case. The behavior of those estimators is studied in both large and finite sample situations. Monte Carlo simulations reveal that both estimators provide good approximations of their respective inferential targets. Data from the Health and Lifestyle Study are used for studying the relationship of the tobacco use and the age of death and illustrate the practical application of the proposed technique. gHR is a promising index which can help facilitate better understanding of the association of one study factor on a time-dependent outcome.
On Police-Military Cooperation in Peacetime: Constitutional and Ethical-Political Memorandum
Authors: Teršek Andraž 
Published: August 2021

Abstract
Among the more important socio-political issues that have appeared on the surface of the public agenda is the question of cooperation between the police and the army. In the article, the author analyzes this issue both in general and in the specific context of the Republic of Slovenia. He explains that the Slovenian Government did not formally declare a “state of emergency,” although the Slovenian Constitution allows it, but officially declared an epidemic and used a special provision in the Defense Act that allows the Slovenian Army to take action in so-called “exceptional” social circumstances and establish police-military cooperation on the ground. The author explains the constitutional dimensions of such cooperation and its ethico-political perspective.
Dynamics of a rotating hollow FGM beam in the temperature field
Authors: Wang Yaolun , Yang Chaofan , Zhang Yongxin , Dong Shipeng , Li Liang 
Published: August 2021

Abstract
Dynamic responses and vibration characteristics of a rotating functionally graded material (FGM) beam with a hollow circular cross-section in the temperature field are investigated in this paper. The material properties of the FGM beam are assumed to be temperature-dependent and vary along the thickness direction of the beam. By considering the rigid-flexible coupling effect, the geometrically nonlinear dynamic equations of a hub–FGM beam system are derived by employing the assumed modes method and Lagrange’s equations. With the high-order coupling dynamic model, the effect of temperature variations under two different laws of motion is discussed, and the free vibration of the system is studied based on the first-order approximate coupling model. This research can provide ideas for the design of space thermal protection mechanisms.

Abstract
In this paper, we consider a new Sylvester-Kac matrix, i.e., Fibonacci-Sylvester-Kac matrix. We discuss the eigenvalues, eigenvectors and characteristic polynomial of this matrix in two categories based on whether the Fibonacci-Sylvester-Kac matrix order is odd or even. Besides, we also give the explicit formulas for its determinant and inverse.
Internethasználat és szubjektív életminőség vizsgálata az idős generációban
Authors: Ercsey Ida 
Published: August 2021

A TANULMÁNY CÉLJA
Napjainkban az internet egyre fontosabb szerepet tölt be az idős generáció életében. A népesség öregedésével párhuzamosan előtérbe került az idősebb korosztály jólléte és életminősége, valamint elégedettségi szintjének felmérése. Nemzetközi kutatási eredmények alapján az időskorúak internetezési és szabadidős tevékenységei között pozitív irányú kapcsolat mutatható ki. A tanulmány célja az idős generáció internet használatának és social media aktivitásának feltérképezése, és a szubjektív életminőségre gyakorolt hatásának vizsgálata.
ALKALMAZOTT MÓDSZERTAN
Az első kutatási kérdés vizsgálatához szekunder forrást használtunk, az IKT és a szubjektív életminőségi adatok másodelemzésével. A második kutatási kérdésben megfogalmazott összefüggés feltárásához pilotkutatást végeztünk. Az adatgyűjtést 2019-ben, online megkérdezési technikával bonyolítottuk le, a Baby Boom generációhoz tartozó alanyok körében. A minta nagysága 105 fő, amelyben 56 nő (53%) és 49 férfi (46%) adott értékelhető válaszokat. Az adatok elemzése statisztikai módszerek alkalmazásával történt.
LEGFONTOSABB EREDMÉNYEK
Megállapítható, hogy a vizsgált európai országokban, az idős generációban az internet aktivitás és az élettel való elégedettség szintje között pozitív lineáris kapcsolat áll fenn, amelynek a mértéke erős. Az eredmények tükrében kijelenthető, hogy a magyar Baby Boomerek életminőségének megítélése és a közösségi médiahasználat mindennapi életükre gyakorolt hatása között pozitív, erős szignifikáns kapcsolat áll fenn.
GYAKORLATI JAVASLATOK
Az internet és a social media használatára vonatkozó mérések igazolják a mennyiségi változást. Azonban látni kell, hogy a különböző mérési eredmények között eltérések vannak, ami a méréshez használt gyakorisági szintek sajátosságaiból erednek. További gondot jelent a minőségi változások generációs megközelítésben történő vizsgálata, ha a minőségi adatok csak korcsoportos bontásban állnak rendelkezésre, vagy más generációs felosztást alkalmaznak. A kutatási téma mélyebb elemzéséhez egyrészt fel kell tárni az internet és social media aktivitást befolyásoló háttérváltozókat, másrészt az aktív részvételt elősegítő egyéni és társadalmi feladatokat.

A digitalizáció és a vevőkapcsolatok kölcsönhatása – egy szerződéses gyártó példáján keresztül
Authors: Szalkai Zsuzsanna , Mandják Tibor , Simon Judit , Hlédik Erika , Neumann-Bódi Edit 
Published: August 2021

A TANULMÁNY CÉLJA
Általánosan elfogadott, hogy a digitalizálás befolyásolja az üzleti kapcsolatokat, következésképpen a vevőkapcsolatokat is. Kevésbé ismert azonban, hogy hogyan történik ez a befolyás. Továbbá, vajon a vevőkapcsolatok befolyásolják-e a digitalizációt? Tanulmányunk célja, hogy a szerződéses gyártás területén feltárja a digitalizálás és a vevőkapcsolatok közötti összefüggéseket. Feltáró kutatásunkban két kutatási kérdésre keressük a választ: 1) Milyen hatással van a digitalizáció a vevőkapcsolatokra? 2) Hogyan befolyásolják a vevőkapcsolatok a digitalizációt?
ALKALMAZOTT MÓDSZERTAN
Kutatásunk keretében esettanulmányt készítettünk és elemeztünk a Videoton Electronic Assembly Services (VEAS) vállalatról és vevőkapcsolatairól. A digitalizáció és a vevőkapcsolatok kölcsönhatását az Industrial Marketing and Purchasing (IMP) Group megközelítésével, az üzleti kapcsolatok funkcióin keresztül elemeztük. Az IMP elmélet szerint az üzleti kapcsolatok funkciói három szinten, azaz vállalati, kapcsolati és hálózati szinten jelentkeznek.
LEGFONTOSABB EREDMÉNYEK
A vevőkapcsolatokat, az üzleti kapcsolatok funkciói szerint vizsgálva azt találtuk, hogy a vállalati szinten tulajdonképpen az egyes vállalati tevékenységeket szükséges digitalizálni (pl. HR, pénzügy), illetve, hogy a HR egyik fontos feladata a munkaerő „digitális átállítása”. Az üzleti kapcsolat szintjén a vevői elvárásokra adandó rugalmas válaszok különböző szintű és típusú digitális megoldásokat igényelnek. A hálózati szinten, a digitalizáció meglévő szintje az új vevőkapcsolatok kialakításának lehetőségét hordozza magában. Megállapítható, hogy a vevőkapcsolatok és a digitalizáció egyfajta „húzd meg, ereszd meg” szituációban vannak, azaz a vevői igények sokfélesége, a vállalat oldaláról pedig az ezeknek való megfelelés lehetősége jelenti a digitális megoldások kulcskérdését.
GYAKORLATI JAVASLATOK
Menedzseri szempontból kutatásunk fontos tanulsága, hogy amennyiben a digitális átállás során, a menedzserek tudatában vannak és odafigyelnek a digitalizáció és a vevőkapcsolatok kölcsönhatásaira, jobban össze tudják hangolni a vállalati célokat a vevői elvárásokkal a megfelelő digitális megoldásokat alkalmazva. Ez azt jelenti, hogy a menedzsereknek tekintettel kell lennie a digitalizáció különböző típusaira (Pagani & PardO 2017) és a vevőkapcsolatok különböző hatásaira, vállalati, kapcsolat és hálózati szinten egyaránt.
Newborn Pulse Oximetry Screening at a Community Hospital: An 8-Year Experience
Authors: Schwartz Bryanna N. , Hom Lisa A. , Von Kohorn Isabelle , Becker Jeffrey , Cuzzi Sandra S. , Clarke Sue Ellin Grier , Kiernan Sharon C. , Martin Gerard R. 
Published: August 2021

OBJECTIVES
To evaluate newborn pulse oximetry screening (POS) outcomes at a large community hospital and the impact of the recommended revised POS algorithm.

METHODS
A retrospective cohort study was performed to evaluate the results of POS in the well-infant nursery between 2012 and 2020. The POS results were obtained from an electronic platform. Chart review was completed for newborns with failed screens. The recommended revision to POS, no second rescreen, was applied to the data to evaluate screening outcomes.

RESULTS
Of the total 65 414 infants admitted to the well-infant nursery during this 8-year period, &gt;99% (n = 64 780) received POS. Thirty-one infants failed POS (4.6 per 10 000 screened). All infants who failed POS were found to have a disorder, with 12 (39%) having critical congenital heart disease (CCHD), 9 (29%) having non-CCHD requiring further follow-up, and 10 (32%) having noncardiac conditions. One false-negative screen result was identified through the Maryland Department of Health Newborn Screening Follow-up Program. The positive predictive value of POS for those screened was 39% for CCHD, with a specificity of 99.97%. Eliminating the second rescreen in the POS algorithm would have resulted in an additional 5 newborns without CCHD failing POS, increasing the false-positive rate from 0.03% to 0.04%.

CONCLUSIONS
POS is an effective tool for identifying CCHD and secondary conditions. POS was successfully implemented with few missed screens and was highly specific. Elimination of the second rescreen in the pulse oximetry algorithm would have resulted in a minimal increase in false-positive results and faster evaluation of newborns with CCHD.
Joint Regional Waveform, First-Motion Polarity, and Surface Displacement Moment Tensor Inversion of the 3 September 2017 North Korean Nuclear Test
Authors: Chi-Durán Rodrigo , Dreger Douglas S. , Rodgers Arthur J. , Nayak Avinash 
Published: August 2021

AbstractThe 3 September 2017 Mw 5.2 North Korean underground nuclear test (DPRK2017) is the largest man-made explosion with surface displacements observed by Synthetic Aperture Radar (SAR) and showed as much as 3.5 m of horizontal permanent deformation. Although regional distance waveform-based seismic moment tensor (MT) inversion methods successfully identify this event as an explosion, the inverted solutions do not fit the SAR displacement field well. To better constrain the source, we developed an MT source-type inversion method that incorporates surface ground deformation (accounting for free-surface topography), regional seismic waveforms, and first-motion polarities. We applied the source-type inversion over a grid of possible source locations to find the best-fitting location, depth, and point-source MT for the event. Our best-fitting MT solution achieves ∼70% horizontal geodetic fit, ∼80% waveform fit, and 100% fit in the first-motion polarities. The joint inversion narrows the range of acceptable source types improving discrimination, and reduces the uncertainty in scalar moment and estimated yield. The method is transportable and can be applied to other types of events that may have measurable geodetic signals such as underground mine collapses and volcanic events.

Published: August 2021

Market share determines the position of revenue and public utilization of Sharia bank. This research aims to examine the internal and external determinant factors of Indonesia Sharia banking market share. The secondary data were obtained from the Financial Services Authority (OJK) and Bank Indonesia (BI). Autoregressive Distributive Lag (ARDL) was used to explore the short and long periods from the inﬂuence of variables, including total of oﬃces, customers, third-party saving (DPK), and promotion. The results showed that the total number of Automated Teller Machines (ATM) had a contrastingly diﬀerent impact. Therefore, this research recommends adding all variables quantitatively.
