Does Digitalization Boost Unemployment: Spatial Effects and COVID-19 Case
Julia Varlamova,Ekaterina Kadochnikova 대한산업공학회 2023 Industrial Engineeering & Management Systems Vol.22 No.3
The labor market always presupposes a collision of the supply and demand forces. Sharp fluctuations in the economic environment can reduce the demand for labor. In the article, the authors discuss how digitalization changes the labor market, increases its efficiency, but also creates negative effects for its equilibrium. The purpose of the study is au-thors` measurement of the impact of digitalization of households on the unemployment rate, taking into account the spatial heterogeneity of Russian regions on panel data for two periods: 2016-2019 and 2020-2021. We used Moran and Geary spatial correlation indices, an econometric model with spatial lags, and the maximum likelihood method. Also, we show clustering of Russian regions by unemployment rate, strengthening of spatial cooperation of regions by unemployment rate and digitalization of households during the coronacrisis. The findings distinguish that the influ-ence of digitalization of households on the reduction of unemployment existed during the coronacrisis, and it absented in the period preceding the pandemic. The scientific novelty of the study is the measuring the impact of household digitalization on the unemployment rate in the regions of Russia, taking into account spatial effects. The main conclu-sions of the investigation can be used in scientific and practical activities for the implementation of institutional measures for the development of regional labor markets, considering spatial differentiation of Russian regions
Verification of mesoscopic models of viscoelastic fluids with a non-monotonic flow curve
Julia L. Kuznetsova,Oleg I. Skul’skiy 한국유변학회 2016 Korea-Australia rheology journal Vol.28 No.1
The non-monotonic flow curve of a 1 wt.% polyacrylonitrile solution in dimethyl sulfoxide is described by two mesoscopic models: the modified Vinogradov-Pokrovsky model and the model proposed by Remmelgas, Harrison and Leal. To obtain an adequate description of the experimental curve, we have selected suitable internal parameters for these models. Analytical solutions for the Couette-Poiseuille flow problems are determined in parametric form, which allows us to plot the distribution of stress components and anisotropy tensor as well as the velocity profiles containing closed loops and weak tangential discontinuities. It is shown that both models predict a similar qualitative picture of structure evolution, but exhibit a significant discrepancy in the quantitative description of the magnitude of molecular chain stretching.

The ideal of the bodhisattva― ‘great compassion’ is fixed as the major idea of the Mahayana. This ideal became the most popular in Buddhist Asia. In Korea Buddhism appears in the end of the 4th century coming from China, where it was practiced from the end of the 1st century. Buddhism came into Tibet in the 7th century. Many people, monks and statesmen, were considered as terrestrial reincarnations of different bodhisattvas. Cults of bodhisattvas are widespread in the countries where people practice the Mahayana tradition. They have many iconographic forms and images.
Pregnancy following vulvar squamous cell carcinoma: a report of two cases
Julia E Palmer,John A Tidy 대한부인종양학회 2009 Journal of Gynecologic Oncology Vol.20 No.4
Pregnancy following squamous cell carcinoma of the vulvar is rare. Its rarity is reflected by a paucity of cases reported in the literature. We report two cases of pregnancy following diagnosis and treatment for vulvar squamous cell carcinoma, and review eleven prior reported cases. In successfully treated vulvar cancer subsequent pregnancy is not shown to increase the risk of disease recurrence, and there appears to be no deleterious effects during the antenatal period. It is possible, when considering prior reports, that prior vulvectomy may increase the likelihood of delivery by caesarean section, though modifications in the surgical management of vulvar carcinoma may have decreased this risk.

Background: Reverse shoulder arthroplasty (RSA), first introduced as a management option for cuff tear arthropathy, is now an accepted treatment for complex proximal humeral fractures. Few studies have identified whether the outcomes of RSA for shoulder trauma are comparable to those of RSA for shoulder arthritis. Methods: This is a retrospective, single-institution cohort study of all patients who underwent RSA at our institution between January 2013 and December 2019. In total, 49 patients met the inclusion criteria. As outcomes, we evaluated the 1-year American Shoulder and Elbow Surgeons (ASES) and Constant shoulder scores, postoperative shoulder range of motion, intra- and postoperative complications, and cumulative revision rate. The patients were grouped based on preoperative diagnosis to compare postoperative outcomes across two broad groups. Results: The median follow-up period was 32.8 months (interquartile range, 12.6–66.6 months). The 1-year visual analog scale, range of motion, and Constant and ASES functional scores were comparable between RSAs performed to treat shoulder trauma and that performed for arthritis. The overall complication rate was 20.4%, with patients with a preoperative diagnosis of arthritis having significantly more complications than those with a preoperative diagnosis of trauma (34.8% vs. 7.7%). Conclusions: Patients who underwent RSA due to a proximal humeral fracture or dislocation did not fare worse than those who underwent RSA for arthritis at 1 year, in terms of both functional and radiological outcomes.

Backgrounds/Aims: Acute pancreatitis is an emergency presentation, which can range from mild to life threatening. Intravenous fluids are the cornerstone of management. Although the WATERFALL trial described the optimal fluid rate in mild/moderate pancreatitis, this trial excluded patients with moderate-severe/severe pancreatitis. The aim of this study was to establish clinical practice regarding intravenous fluid administration in acute pancreatitis and assess its effect on mortality. Methods: Prospective multi-centre audit of patients with acute pancreatitis was conducted. Data were collected regarding intravenous fluid administration within 72 hours of admission. The primary outcome was 30-day mortality. Multivariable logistic regression was used to identify predictors of 30-day mortality. Results: Those with severe pancreatitis received more fluid; median 5.7 L versus 4 L in 72 hours (p = 0.003). Participants with severe pancreatitis who died within 30 days received a median of 2,750 mL in the first 24 hours, compared to 4,000 mL in those who survived. The following factors were significant predictors of 30-day mortality: age, Glasgow score, C-reactive protein, ischaemic heart disease, and pancreatitis aetiology. Overall, volume of intravenous fluid was not associated with mortality. However, the effect of intravenous fluid volume on mortality differed significantly depending on pancreatitis severity. In severe pancreatitis, increased volume of intravenous fluid was associated with significant reductions in mortality (odds ratio = 0.655; 0.459–0.936; p = 0.020). Conclusions: In severe pancreatitis, more aggressive fluid prescription was associated with decreased mortality; however, this was not the case in milder disease. Further prospective trials guiding fluid resuscitation in severe pancreatitis are needed, as the impact of fluid on this population appears to differ from that in those with milder disease.
