Published: May 2021

This study examined ten sustainable business strategies that more experts have advised use running a business in the new normal era. Many findings went publication on a variety of profitable business strategies. However, very little has discussed in a balanced proportion between gaining profitable business and design with high sustainable value. Conditionally, running a business requires a variety of strategic approaches that are sustainable following the policy of the COVID-19 protocol. Understanding which strategies align with the above expectations, we have conducted a series of online literature studies using qualitative methods based on a phenomenological approach. Then, they were analyzed using the conceptual framework of higher education research skills. Through this process, the authors ensured that these findings are valid and reliable. Finally, we summarized ten relevant, sustainable business strategies that are relevant to be applied in the new normal business era in Indonesia. They include continuity strategy, business to business, opportunity strategy, rethinking, lesson learned strategies, working from home, affected policies, new thinking patterns, flexibility strategies, and understanding of new processes. Therefore, these findings will provide profound insight for business people and academicians to work on business practices' sustainability to facing the pandemic disruption.

The Placenta is an important organ that perform for the exchange of nutrients and oxygen which is needed by the fetus through retro-placenter blood circulation. The poor maternal environment has an impact on placental development and growth in the fetus, one of them is exposure to electric cigarette vapors as a free radicals. A protection that can neutralize free radicals namely lemon as an antioxidant. This study aims to find out the effects of infused of lemon water (Citrus Limon) in preventing increased levels of mice placental Malondialdehyde (MDA) in pregnant mice (Rattus novergicus) that exposed to electric cigarette vapor.The experimental research design uses the Randomized Post Test Only Control Group Design. 30 animals were split into 5 groups,KN,KP, and the 3 treatment group was exposed to electric cigarette vapor and had been infused with lemon water P1=25; P2=50; P3=100 gr lemon/100 ml water. Lemon water infusion and electric cigarette vapor were given on the 18th day, the 19th day was surgically removed, and MDA levels were measured. Most average placental MDA level KN 0.1162; KP 0.5820; P1 0.3106; P2 0.1828; P3 0.2218 ng/100mg. Anova OneWay results have shown there are differences in placental MDA levels between groups p = 0,000 p <0.05. The KP group was significantly different from KN, the P1 group was significantly different from KN, the P1, P2 and P3 groups were significantly different from the KP. However, there has been no significant difference between P3 and P1. In KN there is no difference between P2 and P3, P2 there is no significant difference with P1, and there is no significant difference between P3 and P2. Lemon water infusion can reduce MDA levels in the placenta of pregnant rats exposed to electric cigarette vapor.

At the time toddler, this is the right time for parents to teach children to perform toileting. Children who have not been able to perform toileting properly because of the ability of a child who is not robust like, not yet accustomed to sitting or squatting on the toilet, have not been able to remove his trousers, and some children do who do not know how toileting, requires a method or way that is easily understood by children in teaching toileting, one of which is by video modeling. This study uses Analytical Experimental Design with one-group pretest-posttest design conducted on 34 respondents. The sampling technique uses probability sampling with a simple random sampling method. The instruments used were toileting ability questionnaire and video modeling. The results showed that the ability of child toileting before being given video modeling most of the respondents had sufficient ability, and after being given video modeling almost all respondents had good abilities. This is evidenced by the Wilcoxon test obtained p-value = 0,000 (α <0.05) where 0,000 <0.05 then there is an influence of video modeling on the ability of toileting toddler children in the Bunda Padasan Permata study group. From the results of this study, it can be concluded that video modeling can be used as an alternative to toileting learning media in toddler-age children.

Motorbike gang network in Yogyakarta: Socio-cultural studies between the relation of moral and religion habituation of local teenagers
Authors: Birsyada Muhammad Iqbal , Kintoko Kintoko , Mehta Kunal
Published: May 2021

The study of the phenomenon of the Motorcycle Gang known as Klithih in Yogyakarta at this time is very important and urgent to conduct in order to find various shifts in moral and religious values experienced by adolescents who are members of the Klithih Gang, especially from the perspective of social and religious studies. Thus, this research is expected to provide a solution, especially for the Yogyakarta local government, to overcome various motorcycle gang behavior models, mostly carried out by the school-age youth community. The differences between the previous study and this study are; First, this research focused on the Motorcycle Gang case in Yogyakarta, which has not been studied much by other researchers. Second, this study used a qualitative approach with a phenomenological framework to get a deeper picture of the motor gang involvement process in social and educational aspects. Third, the research locus was in the city of Yogyakarta. Fourth, this study used a combined theoretical conception of social theory and moral values to analyze the interpretation of the research results. The findings of this study are described as follows. First, the Motorcycle Gang's behavior occurs because of the failure to internalize moral and religious education in the family. Psychological and physical violence that occurs in the families of motorcycle gang perpetrators affects children's brain and psychological development. The condition of the two parents who experienced a divorce (broken home) made the children feel traumatized, so they look for an environment that accepts them outside. Second, the influence of their friendly environment is very dominant in triggering teenagers to join the Motor Gang group. Third, the community's social and religious lack control in preventing activities of Motorcycle Gangs around their places of residence. Fourth, students or alumni who are involved in the Motorcycle Gang network indicated a lack of preventive action from schools. Fifth, the shift in socio-religious values in the Gang Motor community occurred because of an appeal for the Klithih group to get recognition from other Motorcycle Gang groups by showing the level of their mental strength among the Gang members.

The purpose of this study was to explore the correlation between Heath Carter somatotype component factors that affect physical fitness. This study was a cross-sectional research design was used with 43 athletes in PB Djarum Kudus who were selected purposively to be the respondents. The data on Heath Carter somatotype was obtained from anthropometric measurements to generate somatotype scores, namely endomorphy, mesomorphy, and ectomorphy. Cardiorespiratory endurance data were obtained using Balke test, power using vertical jump, and agility using court agility. The somatotype component types of all athletes are central (4.2-4.1-3). Male athletes are of central type (3.5-4-3.5) and females are of mesomorph-endomorph type (5-4-2). Both endomorphy and ectomorphy components showed significant correlation with cardiorespiratory endurance except mesomorphy component. Endomorphy component showed significant correlation with power except for mesomorphy and ectomorphy components. The ectomorphy component with a slender body shape with long arms and legs, low body fat percentage and strong muscle in the arms make it easier for badminton athletes to move in all positions combined.

This paper proposes a Wind Turbine Emulator (WTE) using an Indirect Field Oriented (IFO) Induction Motor (IM). The IM drive can be controlled as a conventional prime mover in speed mode, or a wind turbine in torque-speed mode via robust observed torque control. This paper presents key issues for establishing a high-performance IFO IM drive. Further, this study develops a wind turbine load Interior Permanent-Magnet Synchronous Generator (IPMSG) followed by a three-phase Vienna Switch-Mode Rectifier (SMR). It receives mechanical driven power from the WTE and establishes a 400V DC-link for the DC micro-grid. The good generating characteristics are achieved through proper controls of both the IPMSG and SMR. Various wind turbine torque-speed and power-speed characteristic curves under different wind speeds can be emulated by the developed WTE. The designed results are verified by simulations. The measured results indicate that the errors are within 1.5% and 1.0%, respectively, for the torque and the power compared to the designed ones. The maximum power point tracking (MPPT) function with good performance for the PMSG with Vienna SMR is achieved using the perturb and observation (P&O) approach. The dynamic and steady-state operating characteristics of the developed whole turbine emulator driven PMSG system are assessed experimentally.

Because lithium metal exhibits high specific capacity and low potential, it is the best candidate for fabricating anodes for batteries. Rechargeable batteries fabricated using lithium anode exhibit high capacity and high potential cathode; these can be potentially used to fabricate high energy density batteries (>500 Wh kg–1) that can be used for the development of next-generation electric vehicles. However, the formation and growth of lithium dendrites and the low coulombic efficiency recorded during lithium plating and stripping under conditions of high current density hinder the use of lithium metal as the anodic material for the development of practical rechargeable batteries. In this short review, we outline the current status and prospects of lithium anodes for fabricating batteries in the presence of non-aqueous liquid, polymer, and solid electrolytes operated under conditions of high current density.
Toxicological and ecotoxicological pressure assessment on the use of synthetic pesticides in Sancti Spíritus, Cuba
Authors: Lopez-Dávila Edelbis , Houbraken Michael , De Rop Jasmine , Du Laing Gijs , Romero Romero Osvaldo , Spanoghe Pieter
Published: May 2021

A study to quantify the toxicity and ecotoxicological pressure of pesticides in the Sancti Spíritus province, Cuba, was carried out between 2011 and 2014. A longitudinal descriptive work was designed for the study period to identify potential risks to the environment and also to human health associated with the use of pesticides in the country. The Spread Equivalents (ƩSeq) and Pesticide Occupational and Environmental Risk (POCER) indicators, as well as the Toxic Load (TL) methodology of Instituto Cubano de Sanidad Vegetal, were used to determine the toxicity and ecotoxicity of pesticide use. One hundred and twenty-four active ingredients corresponding to 62 chemical families were applied in the province during the study period. Organophosphates, triazoles, sulfonylurea, pyrethroids, inorganic compounds (such as copper), carbamates, dithiocarbamates, neonicotinoids, aryloxyphenoxypropionates, and organochlorines predominated due to their use frequency. The use of toxic pesticides, and the lack of personal protection equipment, among others, made workers, residents, and applicators the toxicological modules with the highest risk of exposure. On the other hand, aquatic organisms, and the persistence of the pesticides in the soil and in groundwater, are the modules with the highest ecotoxicological pressure. By using the POCER and ƩSeq indicators, a more accurate toxicity and ecotoxicity assessment for certain pesticides can be performed in Cuba, in comparison to the one obtained when using only the TL equation currently employed in the country. In addition, substituting the most toxic pesticides (e.g., parathion, endosulfan, bifenthrin, copper oxychloride, mancozeb, paraquat, diquat, and ametryn) with less toxic ones (e.g., cypermethrin, tebuconazole, triadimenol, and bispyribac-sodium) could help reduce synthetic pesticide pressure on humans and the environment.
Mobile Apps for Drug–Drug Interaction Checks in Chinese App Stores: Systematic Review and Content Analysis
Authors: Shen Chunying , Jiang Bin , Yang Qilian , Wang Chengnan , Lu Kevin Z , Gu Meng , Yuan Jing
Published: May 2021

Background

As a computerized drug–drug interaction (DDI) alert system has not been widely implemented in China, health care providers are relying on mobile health (mHealth) apps as references for checking drug information, including DDIs.

Objective

The main objective of this study was to evaluate the quality and content of mHealth apps supporting DDI checking in Chinese app stores.

Methods

A systematic review was carried out in November 2020 to identify mHealth apps providing DDI checking in both Chinese iOS and Android platforms. We extracted the apps’ general information (including the developer, operating system, costs, release date, size, number of downloads, and average rating), scientific or clinical basis, and accountability, based on a multidimensional framework for evaluation of apps. The quality of mHealth apps was evaluated by using the Mobile App Rating Scale (MARS). Descriptive statistics, including numbers and percentages, were calculated to describe the characteristics of the apps. For each app selected for evaluation, the section-specific MARS scores were calculated by taking the arithmetic mean, while the overall MARS score was described as the arithmetic mean of the section scores. In addition, the Cohen kappa (κ) statistic was used to evaluate the interrater agreement.

Results

A total of 7 apps met the selection criteria, and only 3 included citations. The average rating score for Android apps was 3.5, with a minimum of 1.0 and a maximum of 4.9, while the average rating score for iOS apps was 4.7, with a minimum of 4.2 and a maximum of 4.9. The mean MARS score was 3.69 out of 5 (95% CI 3.34-4.04), with the lowest score of 1.96 for Medication Guidelines and the highest score of 4.27 for MCDEX mobile. The greatest variation was observed in the information section, which ranged from 1.41 to 4.60. The functionality section showed the highest mean score of 4.05 (95% CI 3.71-4.40), whereas the engagement section resulted in the lowest average score of 3.16 (95% CI 2.81-3.51). For the information quality section, which was the focus of this analysis, the average score was 3.42, with the MCDEX mobile app having the highest score of 4.6 and the Medication Guidelines app having the lowest score of 1.9. For the overall MARS score, the Cohen interrater κ was 0.354 (95% CI 0.236-0.473), the Fleiss κ was 0.353 (95% CI, 0.234-0.472), and the Krippendorff α was 0.356 (95% CI 0.237-0.475).

Conclusions

This study systematically reviewed the mHealth apps in China with a DDI check feature. The majority of investigated apps demonstrated high quality with accurate and comprehensive information on DDIs. However, a few of the apps that had a massive number of downloads in the Chinese market provided incorrect information. Given these apps might be used by health care providers for checking potential DDIs, this creates a substantial threat to patient safety.
THE RELATIONSHIP BETWEEN URIC ACID LEVELS AND GRAFT FUNCTION IN RENAL TRANSPLANT PATIENTS WHO DISCONTINUED STEROID THERAPY

Published: May 2021

Introduction: High uric acid levels are commonly encountered in kidney
transplant recipients, and can be associated with allograft dysfunction.
Our study aims to examine the relationship between UA levels and graft
function in patients discontinuing steroids. Methods: In this
single-center-retrospective study, 56 patients from among 678 RT
patients transplanted from living donors between 1999-2020 were
included. Causes of steroid discontinuation, creatinine levels
concurrent with uric acid levels before and after steroid
discontinuation (mean 3.9 ± 2.1 years), acute rejection numbers,
demographics, durations of dialysis and transplantation, medications
(d.a. use of immunosuppressive, antihypertensive), laboratory data,
human leukocyte antigen (HLA) mismatch numbers, blood-pressure [BP],
body mass index, late acute rejection (LAR) numbers (3 months
post-transplantation) were all recorded. Results: Creatinine and uric
acid levels were seen to have increased after steroid discontinuation,
there was a significant relationship between them (p<0.001).
Statistically significant correlation was found between increased
creatinine levels after steroid discontinuation and graft survival with
higher HLA mismatch; 39 (69.6%) patients with mismatch ≥2, and 17
patients with mismatch <2 (30.4%) (p=0.049) . No significant
relationship was found between LAR numbers before and after steroid
discontinuation, and creatinine levels after steroid discontinuation. In
conclusion, per model obtained as a result of multivariate linear
analysis, hyperuricemia and HLA mismatch numbers (p= 0.048 and p= 0.044,
respectively) are independent predictive factors for graft dysfunction
in patients discontinuing steroids. Accordingly, negative effects of
modeling should be kept in mind for long-term graft survival in patients
who plan to continue with steroid-sparing regimens.

oral-fecal and a very low oral dose is enough to infect susceptible
pigs, causing devastating consequences in production. A 10,000-sow
farrow-to-wean farm located in northwest Mexico was infected with PEDV.
After the observation of the first clinical signs, an outbreak
investigation take into place to determine the most probably source of
infection. A systematic collection of samples including rectal swabs,
gestation and lactation feed, surface swabs from the interior or feed
bins and many points of the feed truck delivering the implicated feed
was performed. Samples were tested for PEDV polymerase chain reaction
(PCR). Positive PCR results showed the evidence of PEDV RNA in lactating
feed, the interior walls of the feed bins and in the interior of the
auger boom of the feed truck. This, connected with the location of first
clinical signs point that the most probably incursion of PEDV in to this
breeding herd was contaminated feed. This paper shows how feed or feed
transport can be a potential source of PEDV infection in farms and
highlight the importance of stablishing biosecurity programs to mitigate
the risk of PEDV infections.

Objective To compare the cumulative live birth rate per egg retrieval
between time lapse imaging (TLI) incubators and standard culture (SC)
incubators both using a single-step culture medium Design Retrospective
cohort study Setting A tertiary level fertility-centre Population Women
undergoing an IVF cycle between November 2015 and December 2017 Methods
Comparison was done between 1219 IVF cycles using TLI and 1039 cycles
using SC after accounting for confounding factors such as age and number
of oocytes retrieved. Main outcome measure Cumulative live birth rate
per egg retrieval Results The live birth rate per egg retrieval
following fresh embryo transfer was noted to be higher for TLI cycles
(TLI 39.87% vs SC 38.02%, aOR 1.20, 95% CI 1.01 to 1.44). More
embryos were available for cryopreservation in the TLI arm (MD 0.08
embryos, 95% CI 0.10 to 0.41). The live birth rate per frozen embryo
transfer was not significantly different. The cumulative live birth rate
per egg retrieval was significantly higher in the TLI arm (TLI 50.29%
vs SC 46.78%, aOR 1.24, 95% CI 1.04 to 1.48) Conclusions With the use
of single step medium, there appears to be a greater benefit of TLI
through a reduced interruption in embryo culture conditions, resulting
in a higher number of embryos available for cryostorage which in turn
appears to improve the cumulative live birth rate. Funding No funding
was obtained for this study Keywords Time lapse imaging, cumulative live

The article is devoted to the increasing role and prospects for the development of e-learning in modern transformation of higher polytechnic education. In the context of preventing the spread of coronavirus infection COVID-19 and the transition of universities to various forms of distance education, this issue is of particular relevance. The aim of the study is to assess the process of introducing e-learning into the educational process of higher technical educational institutions in Russia. The methodological basis of the work was the analytical and systematic approach to the study of the object of research using methods of data systematization, evaluative analysis and forecasting, as well as logical generalization. The authors come to the conclusion that the introduction of e-learning in technical universities in Russia until recently played a supporting role in the reorganization and optimization of the processes of training engineering personnel. The development of e-learning helped to reduce the costs of the educational process, reduce the number of employees, as well as solve the problem of the classroom fund. An important role in the development of e-learning was played by the desire to increase the rating indicators. The desire to expand non-budgetary sources of funding for modern technical universities and the possibility of implementing new learning models were only additional incentives for expanding the e-learning system. The results of this study can be used in further studying the digitalization of higher education and assessing the prospects for the development of professional training in Russia.

Moods and metabolism modulate each other. High comorbidity of depression and metabolic disorders, such as diabetes and obesity, poses a great challenge to treat such conditions. Here we report the therapeutic efficacy of brain-derived neurotrophic factor (BDNF) by gene transfer in the dorsal raphe nucleus (DRN) in a chronic unpredictable mild stress model (CUMS) of depression and models of diabetes and obesity. In CUMS, BDNF-expressing mice displayed antidepressant- and anxiolytic-like behaviors, which are associated with augmented serotonergic activity. Both in the diet-induced obesity model (DIO) and in db/db mice, BDNF ameliorated obesity and diabetes, which may be mediated by enhanced sympathetic activity not involving DRN serotonin. Chronic activation of DRN neurons via chemogenetic tools produced similar effects as BDNF in DIO mice. These results established the DRN as a key nexus in regulating depression-like behaviors and metabolism, which can be exploited to combat comorbid depression and metabolic disorders via BDNF gene transfer.
Osäkerhetens politik i praktiken: Presidentvalet 2020 som förändrade Belarus

Abstract: ‘The Politics of Uncertainty’ in Practice: The 2020 Presidential Election that Changed BelarusUp until 2020 Aleksandr Lukashenka’s authoritarian regime had ruled Belarus for 26 years without major challenges. Thus, the popular mobilization that took shape in connection with the August 2020 presidential election came as a surprise. It was not the first time that elections in Belarus were not fair – but it was the first time that large sectors of the population reacted openly. Six months later, Belarusians all over the country were still contesting the falsified results. What contributed to this mobilization and politicization of a previously largely apolitical society? Why does that development represent such a serious threat to the authoritarian system? This study sees the Belarusian presidential election and its aftermath as illustrating the ‘politics of uncertainty’ of electoral authoritarian regimes. Because of the intrinsic insecurity of authoritarian systems, all regular elections in that context entail risks, which in theory might lead to change. In Belarus, the emergence of latent threats to the regime’s legitimacy in the form of social cleavages and an economic crisis, combined with the fundamental dynamics of the ‘election game’, amplified this instability. The election served as the starting point for a process of transformation that became the most serious threat ever faced by the Lukashenka regime.

“Defender of the West”: Henri Massis against Spengler, Hitler and Germany
Authors: Molodiakov Vasily E.
Published: May 2021

This article analyzes the position on German civilization and different political regimes in Germany of the French conservative political philosopher Henri Massis (1886-1970). Catholic and French nationalist, follower of Maurice Barrès and Charles Maurras, Massis during all his life remained a Germanophobe and saw Germany, as well as Russia, not belonging to European civilization and being a dangerous enemies of the “West”. According to Massis ‘the West’ was limited to the Roman-Catholic part of Europe with France in the center, as the inheritor of Hellenized Christian Rome. Massis considered that civilization as the sole ‘authentic’ one. For many years Massis critisized the views of Oswald Spengler as representative of the “catastrophic theory of history” and precursor of national socialism.
