Published: May 2023

В статье представлены результаты проведенного выборочного исследования рынка труда аудиторов в российских городах - центрах Федеральных округов, в ходе которого выявлен потенциальный риск того, что в скором времени рынок окажется неспособным удерживать высококвалифицированных специалистов с современными цифровыми компетенциями в сфере аудита при условии сохранения текущего уровня оплаты труда таких профессионалов и высоких требований к их компетенциям. Как следствие, на рынке складывается ситуация, которая затрудняет цифровизацию аудиторской деятельности.
The paper presents the results of a sample survey of the labor market of auditors in Russian cities - centers of the Federal Districts. During the research a potential risk was identified that soon the market would be unable to retain highly qualified specialists with modern digital competencies in the field of audit, if the current level of salary of such professionals and high requirements for their competencies remain. As a result, the market is facing a situation that makes it difficult to digitize audit activities.
MODEL ASSESSMENT OF THE MECHANISM OF FUNCTIONING OF FINANCIAL AUTHORITY
Authors: Ерженин Р.В. 
Published: May 2023

Повышение производительности финансовой деятельности относится к одной из наиболее актуальных, но малоизученных направлений в современной теории государственного управления. В данном исследовании предлагается новая концепция, позволяющая решить проблему накопления резервов неэффективности в виде излишней численности специалистов за счет использования системной методологии DEA и принципов междисциплинарной науки сервисологии. Основа предложенной оценки сравнительной эффективности базируется на выявленной в результате анализа современных методик связи между численностью населения муниципального образования (далее - МО) и численностью финансового аппарата. Новая модель оценки позволила получить табличные и визуальные данные как об эффективных механизмах управления, так и о неэффективных, т.е. обладающих резервом неэффективности. Для неэффективных объектов в качестве направления в пространстве производственных возможностей использования информационной технологии обозначены объекты-цели. Разработанная модель оценки может использоваться для оценки эффективности информационных систем различных структур управления, имеющих разветвленную сеть учреждений и выполняющих однотипные функциональные задачи.
Improving the performance of financial activities is one of the most relevant, but little-studied areas in modern theory of public administration. In this study, a new concept is proposed that allows to solve the problem of accumulating reserves of inefficiency in the form of an excessive number of specialists through the use of the DEA system methodology and the principles of the interdisciplinary science of serviceology. The basis of the proposed assessment of comparative efficiency is based on the relationship between the population of the Moscow region and the size of the financial apparatus, revealed as a result of the analysis of modern methods. The new assessment model made it possible to obtain tabular and visual data on both effective management mechanisms and ineffective ones, i.e., having a reserve of inefficiency. For the latter, objects-targets are designated as a direction in the space of production possibilities of information technology. The developed assessment model can be used to assess the effectiveness of information systems of various management structures that have an extensive network of institutions and perform the same type of functional tasks.

Published: May 2023

В наше время все больше финансовых учреждений и сфер бизнес-ритейла переходят на использование микросервисных приложений. Это обусловлено удорожанием поддержки полноценной виртуальной инфраструктуры, удобством микросервисов в обслуживании и обеспечении отказоустойчивости. Однако для создания полноценно защищенной от внешнего или внутреннего воздействия среды микросервисных приложений требуется грамотная настройка кластера. В статье рассмотрено несколько концепций для развертывания нового кластера, в частности в среде Azure Kubernetes Service (AKS).
Nowadays, more and more financial institutions and business retail sectors are switching to the use of microservice applications. This is due to the increased cost of supporting a full-fledged virtual infrastructure, the convenience of microservices in service and ensuring fault tolerance. However, to create a fully protected environment from external or internal impact of microservice applications, competent configuration of the cluster is required. The article discusses several concepts for deploying a new cluster, specifically in an Azure Kubernetes Service (AKS) environment.

Published: May 2023

В условиях глобализации мировой экономики, экономической нестабильности одним из наиболее сложных вопросов, с которым сталкиваются менеджеры компаний, является определение оптимальной структуры капитала, которая будет содействовать достижению основной цели компании – максимизации ее акционерной стоимости и благосостояния ее собственников. В рамках стоимостного подхода к оценке бизнеса в работе была сформулирована экономико-математическая модель оптимальной структуры капитала, позволяющая построить различные сценарии распределения капитала с учетом плановых результатов финансово-хозяйственной деятельности, при которой акционерная стоимость как основной критерий эффективности деятельности компании примет максимальное значение при заданном уровне долговой нагрузки. Нами было рассчитаны доходность собственного капитала по модели CAPM, при расчете ставки использовался глобальный подход, который учитывал несистематические риски, рассчитана средневзвешенная стоимость капитала и стоимость компании для каждого возможного уровня долговой нагрузки. Было проведено сценарное моделирование оптимальной структуры капитала на примере компании-производителя комбикормов.
Given the globalization of the economy and the economic instability, one of the most complex issues facing company managers is the determination of the optimal capital structure that will facilitate the achievement of the company's main goal of maximizing its shareholder value and the welfare of its owners. As part of the value approach to business valuation, an economic and mathematical model of the optimal capital structure was formulated in the work, making it possible to create various capital allocation scenarios taking into account planned financial and business performance, when shareholder value, as the main criterion for the company's performance, takes on the maximum value at a given level of debt burden. We calculated the return on equity under the CAPM model, used the global approach to calculating the rate, which took into account non-systemic risks, calculated the weighted average cost of capital and the company's value for each possible level of debt burden. We performed scenario modeling of the optimal capital structure based on the example of a feed producer.

Keratometry Agreement Between Two Swept-Source OCT Devices in Healthy and Post-refractive Surgery Eyes
Authors: Martínez-Albert Noelia , Nieto-Fernández Juan Carlos , García-Marqués José Vicente 
Published: May 2023

Purpose:
To evaluate the keratometry agreement between two swept-source devices for healthy and post-refractive surgery eyes and compare them.

Methods:
One hundred volunteers between 20 and 55 years of age were recruited for this study including both healthy and post-refractive surgery eyes. Three consecutive measurements of simulated keratometry (Sim K), posterior keratometry (PK), and total keratometry (TK) were obtained with the IOLMaster 700 and Anterion. The agreement was assessed through the Bland-Altman method. Limits of agreement (LoA) were calculated as mean difference ±1.96·SD and it represents the 95% of the differences between devices.

Results:
For both groups, Sim K measurements exhibited a mean difference close to 0 and within a range of ±0.30 and ±0.36 diopters (D) for the control and post-refractive surgery groups, respectively. Meanwhile, the IOLMaster 700 provided flatter PK values (0.30 D on average) for both groups. In general, the post-refractive surgery group exhibited slightly greater mean differences and wider 95% LoA than the control group for Sim K and PK. Steeper TK values were obtained by the IOLMaster in both groups (control = 0.50 D and post-refractive surgery = 0.75 D). TK differences between devices were significantly greater in the post-refractive surgery group (ranging from 0.38 to 1.14 D) compared to the control group (ranging from 0.15 to 0.85 D).

Conclusions:
The IOLMaster 700 and Anterion are not interchangeable for TK measurements and eyes that had corneal refractive surgery even decreased the agreement between devices. Differences between devices for Sim K and PK measurements should be clinically judged, particularly in eyes with previous corneal surgery.

Refractive Changes After Implantation of Reversed Intraocular Lens in Cataract Surgery: A Mathematical Model
Authors: Yang Hongseok , Matinrad Hedieh , Goldbaum Michael H. , Bu Jennifer J. , Fukuoka Hideki , Afshari Natalie A. 
Published: May 2023

Purpose:
To develop a mathematical model that can predict the amount of refractive change caused by implantation of an intraocular lens (IOL) in a reversed position during cataract surgery.

Methods:
A theoretical mathematical formula based on the Gullstrand eye model was constructed to estimate the refractive change of the eye after implantation of a reversed IOL. The refractive change caused by implantation of the IOL in a reversed position was calculated based on the exchange of the anterior curvature with the posterior curvature of the IOL, and the lengthening of the distance between the IOL and the retina. In case of a three-piece IOL with angulation, the amount of refractive change was calculated based on its angle and the total refractive power of the eye, which is dependent on the focal length of the eye.

Results:
Calculated refractive change for one-piece IOLs was less than 0.10 diopter (D). For three-piece IOLs, the calculated refractive change makes the eye on average 0.77 D more myopic and can increase with the total refractive power of the patient's eye. The mathematical model was applied to seven previously published cases of reverse IOL implantation.

Conclusions:
This calculation demonstrates that with an upside-down IOL, there is a small refractive change in the one-piece IOL, including a toric IOL without angulation, but there can be a large refractive change in the three-piece IOL with angulation, especially using a higher power IOL or with a shorter axial length.

Refractive and Visual Outcomes of SMILE for Compound Myopic Astigmatism With the VISUMAX 800
Authors: Reinstein Dan Z. , Archer Timothy J. , Potter Joseph G. , Gupta Ruchi , Wiltfang Rainer 
Published: May 2023

Purpose:
To report the first refractive and visual outcomes of small incision lenticule extraction (SMILE) using the VISUMAX 800 femtosecond laser (Carl Zeiss Meditec AG).

Methods:
This was a retrospective analysis of consecutive eyes treated by SMILE using the VISUMAX 800 femtosecond laser at London Vision Clinic, EuroEyes Group, London, United Kingdom. Inclusion criteria were patients aged younger than 45 years, a corrected distance visual acuity (CDVA) of 20/20 or better, and the 3-month postoperative timepoint data being available for analysis. Standard outcomes analysis and vector analysis by the Alpins method were performed.

Results:
During the study period, 128 eyes of 66 consecutive patients were treated. Three-month data were available for 118 eyes (92%), and 10 eyes (8%) were lost to follow-up. The mean attempted spherical equivalent refraction (SEQ) was −4.65 ± 1.91 diopters (D) (range: −1.90 to −10.05 D) and the mean cylinder was −0.98 ± 0.78 D (range: 0.00 to −4.00 D). The mean age was 30 ± 5 years (range: 20 to 43 years), with 54% women and 46% men. Postoperative SEQ was within ±0.50 D in 86% and ±1.00 D in 100% of eyes. Uncorrected distance visual acuity was 20/20 or better in 91% of eyes. One line of CDVA was lost in 8% of eyes, and no eyes lost two or more lines. There was a small but statistically significant increase in contrast sensitivity at 3, 6, 12, and 18 cpd.

Conclusions:
Early outcomes data for SMILE with the second generation VISUMAX 800 femtosecond laser demonstrated an effective and safe option equivalent to published first generation VisuMax outcomes for the treatment myopia and astigmatism.

Authors: Wallerstein Avi , Gauvin Mathieu , Trottier Pierre , Cohen Mark , Lloyd John , Racine Louis , Albert Darren , Ahmed Iqbal Ike K. , Mimouni Michael 
Published: May 2023

Purpose:
To assess the outcomes of a novel toric trifocal intraocular lens (IOL) for refractive lens exchange (RLE) in a large series of eyes with corneal astigmatism.

Methods:
Consecutive eyes that underwent RLE with the PanOptix Toric IOL (Alcon Laboratories, Inc) were included. Outcomes measures included postoperative distance (UDVA), 60 cm intermediate (UIVA), and 40 cm near (UNVA) uncorrected visual acuity, manifest refraction, spherical and defocus equivalent, efficacy and safety indices, and vector analyses of refractive and toric IOL accuracy.

Results:

A total of 4,933 eyes had a median follow-up of 3 months. UDVA of 20/20 and 20/40 was obtained in 65% and 99% of eyes monocularly and 87% and 100% binocularly, respectively. UIVA at 60 cm of 20/25 and 20/40 was achieved in 70% and 99% of eyes monocularly and in 77% and 100% binocularly, respectively. UNVA at 40 cm of 20/25 and 20/40 was achieved in 85% and 96% of eyes monocularly and in 95% and 100% binocularly, respectively. A total of 67%, 89%, 97%, and 99% of eyes had a SEQ within 0.25, 0.50, 0.75, and 1.00 diopter (D) of intended target (
R

= 0.99). Postoperative refractive astigmatism of 0.50, 0.75, and 1.00 D or less was achieved in 86%, 95%, and 98% of eyes. The vector analysis correction index and index of success were 1.04 ± 0.35 and 0.41 ± 0.31 for toric IOL accuracy and 1.00 ± 0.46 and 0.36 ± 0.55 for refractive accuracy, respectively. The 3- and 12-month post-RLE excimer laser enhancement rates were 1.1% (95% CI: 0.8% to 1.4%) and 7.6% (95% CI: 6.9% to 8.3%), respectively.

Conclusions:
The PanOptix Toric IOL performed well for a wide range of axial lengths and corneal astigmatism in eyes that had RLE. Most patients achieved effective uncorrected binocular near, intermediate, and distance vision for daily functioning.

Influence of the Reference Center on the Calculation of Corneal Higher Order Aberrations
Authors: Smadja David , Greenbaum Assaf , Shoshani Avi , Abulafia Adi , Zadok David , Lavy Itay 
Published: May 2023

Purpose:
To evaluate the differences in corneal wavefront measurements in myopic and hyperopic eyes when calculated using three different reference centers and explore possible influencing factors for such differences.

Methods:
Corneal wavefront measurements were performed in myopic and hyperopic eyes using a GALILEI Placido Dual Scheimpflug Analyzer (Ziemer Ophthalmic Systems AG). Corneal higher order aberrations (HOAs), including total, vertical, and horizontal coma-like aberrations, spherical aberrations, and total corneal HOAs through a 6-mm pupil size, were calculated over three different reference center positions: pupil center, corneal vertex, and limbus to limbus. Values were then compared between the myopic and hyper-opic eyes, and correlations with kappa distance and spherical equivalent were tested.

Results:
A significant decrease in the level of total corneal HOAs (−0.04 ± 0.05 and −0.12 ± 0.09), total corneal coma (−0.07 ± 0.09 and −0.18 ± 0.12), and horizontal coma (−0.07 ± 0.11 and −0.22 ± 0.11) in myopic and hyperopic eyes, respectively, was found when recalculating from pupil center to corneal vertex centration, whereas a significant increase in the same aberrations was observed from pupil center or corneal vertex to limbus to limbus. Significant correlations were found between the kappa distance and changes in total corneal HOAs, total corneal coma, and horizontal coma from the pupil center to the corneal vertex in both groups.

Conclusions:
Corneal vertex centration generated the lowest level of corneal wavefront error in both groups. The differences in corneal aberrations between the reference centers for calculation were highly correlated with the kappa distance in hyperopic eyes.

Lo divino como posibilidad de superación del racionalismo ilustrado en el pensamiento de María Zambrano (1904-1991)
Authors: Núñez Aguilera Miguel Ángel 
Published: May 2023

Dentro de las diversas visiones críticas que de la modernidad se han realizado a lo largo del siglo XX, la malagueña María Zambrano nos ofrece una reflexión original y sugerente sobre el significado y la transcendencia del descubrimiento cartesiano del existente humano como cogito. El hombre nacido de la modernidad ha experimentado una merma progresiva y honda de la amplitud de su ser persona a favor de una consideración de sujeto; con ello, también la realidad ha quedado reducida a mero objeto de razón. El resultado es un hombre abismado, que vive de espaldas a la realidad, y por tanto enemistado con la verdad tal como ella se ofrece en lo real, y en consecuencia cerrado desde dentro a la transcendencia. Frente a los postulados de la modernidad, Zambrano desarrolla una razón radicalmente abierta a la vida y constituida en trascendencia.
