Published: March 2022

Male Infertility Oxidative System (MiOXSYS) has been proposed as a rapid and promising technology for the evaluation of sperm oxidative stress. In this case–control study, 134 men with normal sperm parameters (NSP) and 574 men with abnormal sperm parameters (ASP), according to the World Health Organization sperm assessment references values established in 2010, were enrolled. Conventional sperm parameters were evaluated in all patients. Sperm static oxido-reduction potential (sORP) was assessed using the MiOXSYS. Sperm DNA integrity was measured in 604 patients. To ensure that sperm concentration was not a confounding factor in the sORP index ratio, sperm and seminal fluid sORP from 57 randomly selected additional patients were also measured using the MiOXSYS. sORP index (mV/106 sperm/mL) was higher in patients with ASP and seemed to correlate with conventional sperm parameters. Although receiver-operating characteristic analysis revealed that a sORP index cut-off of 0.79 could differentiate normal from ASP with 57.7% sensitivity and 73.1% specificity, these values are much lower than those found in the literature. These values also need to be higher to be applicable in a clinical setting. Furthermore, absolute sORP (mV) was not different in the presence or absence of spermatozoa. sORP index relationships with sperm parameters seem rather be due to sperm concentration, denominator of the sORP index ratio. The establishment of a reliable method using the absolute sORP value, independent of sperm concentration, needs to be addressed. Other oxidative stress biomarkers could be used to validate this method.

Lay summary
The World Health Organization (WHO) has recognized that oxidative stress may have a role in male infertility. Oxidative stress happens when there is an imbalance between the production of molecules containing oxygen and the antioxidants, molecules that neutralize the molecules containing oxygen. The molecules containing oxygen can cause damage to sperm DNA. This damage can be measured using a particular index and this study looked at whether the concentration of the sperm sample might have an impact on results and suggests this should be taken into consideration by clinicians and researchers.

Published: March 2022

Employee competencies are considered to be the most important factor, which determines competitiveness among job seekers and an essential capital in most sectors of the economy. Today, due to the changing conditions in the labor market, the once acquired knowledge and abilities no longer meet the changed requirements, it is becoming important to develop generic and subject specific competencies. The article analyzes the generic and subject specific competencies of future specialists in the Lithuanian tourism sector, which are needed in the labor market of Lithuania from the point of view of employers. Therefore, using a semi-structured in-depth interview, a pilot professional activity field research was carried out in December 2020 – February 2021 in the economically strongest Lithuanian cities. The results of the research showed that due to the ongoing Covid-19 pandemic case, which is resonant and indefinite, the tourism market will never be the same again. It is observed that a person with a broader qualification (i.e. more competencies) easier integrates into the labour market. In this context, priority should be given to the ability of future specialists to be proactive and flexible, entrepreneurial and creative (to understand the specificities, future directions and trends of tourism and recreation services), to use information, smart and other technologies effectively. The specialist will not fear the competition of a professional who already has work experience in tourism sector.
Psicología y emprendimiento
Authors: Ospina Marulanda Daniela , Masmela Laura 
Published: March 2022

En la siguiente presentación se pretende exponer la conexión que hay entre la psicología y el comportamiento emprendedor. Desde sus orígenes y hasta hace no tanto tiempo atrás, la psicología sólo se centraba en la patología, en la debilidad y en el sufrimiento. Actualmente, el acento se pone sobre el bienestar mental o la calidad de vida para que el ser humano pueda, además de vivir saludablemente, salir fortalecido ante las adversidades o crisis que puedan presentársele. Conceptos propios de la psicología positiva como son resiliencia, motivación o felicidad, son cualidades propias del emprendedor, el cual tiene una sensibilidad especial para detectar oportunidades, movilizar recursos, interconectar información o tener ideas innovadoras.
En definitiva, para hallar oportunidades donde otros no las ven o convertir en hechos lo pensado. Tener espíritu emprendedor es hacer las cosas, levantarse con más fuerza cada vez que se cae y ser capaz de convivir con la incertidumbre manteniéndose optimista. Por consiguiente, el estudio del comportamiento y el éxito emprendedor no puede ser correctamente entendido si no se aborda desde la óptica de la psicología positiva.
Ideology in the Time of Pandemic: A Filipino Experience
Authors: Balotol Jr Ruben O. 
Published: March 2022

This paper attempts to hermeneutically explore and understand Filipino moral ideologies in the time of the COVID-19 pandemic. This study frames its ideology from the conceptual tradition of Karl Marx and other philosophers who shared the common idea that ideology has material existence. As Althusser put it, ideology does not exist in the ‘world of ideas’ conceived as a ‘spiritual world,’ but “ideology exists in institutions and the practices specific to them.” This paper discusses first the concept of moral ideology. The discussion focuses morality as ideology that causes a gap between the rich and the poor. Next, it discusses certain Filipino moral ideologies: Utang na Loob (debt of gratitude), Sakop (group)-oriented and Bahala Na. At the same time, it presents how some politicians and high public officials have taken advantage of these ideologies to promote self-interest. Lastly, the relation between Filipino moral ideologies and politics are manifested in the current situation. As a whole, this paper intends to address the question: “what is wrong with the Filipino system that it seems caught unprepared?”

СТУДЕНЧЕСКАЯ СЕМЬЯ В СОВРЕМЕННОЙ РОССИИ: ДЕМОГРАФИЧЕСКИЕ И СОЦИАЛЬНЫЕ ХАРАКТЕРИСТИКИ ПО ДАННЫМ ВЫБОРОЧНОГО ОБСЛЕДОВАНИЯ
Authors: Кучмаева Оксана Викторовна , Золотарева Ольга Анатольевна 
Published: March 2022

Целью исследования является количественная оценка специфики демографических и социально-экономических характеристик молодых семей, имеющих в своем составе студентов, на основе репрезентативной для населения России выборки и определение направлений специализированного выборочного исследования студенческих семей.
Методологическую базу исследования составляют методы демографического и социологического анализа функционирования института семьи, в частности концепция второго демографического перехода, а также методы статистического анализа социологических данных, табличной и графической визуализации данных, расчета дескриптивных статистик и статистических критериев для оценки различий в распределениях.
Результаты исследования. Большая часть молодых людей, получающих профессиональное образование, пока не стремятся вступить в брак и создать семью. Уровень брачности современного российского студенчества незначителен, при этом фактические брачные отношения предшествуют официальной регистрации брака. Данные исследования подтверждают взаимосвязь между официальной регистрацией брака и детностью семей. Однако рождаемость в студенческих семьях значительно ниже, чем в среднем у молодого поколения, а наименьший уровень детности характерен для лиц, получающих высшее образование. Студенты, вступающие в брак, стремятся опираться на свои силы, не рассчитывают на помощь родителей, предпочитают жить отдельно. Это говорит об осознанном подходе к принятию решения о создании семьи. Можно выделить ряд проблем, с которыми сталкивается молодая семья в процессе жизнедеятельности: сложное материальное положение, во многом связанное с рождением детей; жилищные проблемы, которые молодая семья не всегда может решить самостоятельно; начальный этап становления профессиональной карьеры; сочетание семейных и внесемейных ролей. Все это обуславливает нуждаемость в государственной поддержке. Масштабы занятости членов студенческих семей свидетельствуют о необходимости поддержки молодежи на рынке труда: обеспечении гарантий студентов при трудоустройстве, расширении масштабов гибких форм занятости.
Перспективы исследования заключаются в проведении опроса студентов (состоящих и не состоящих в браке) на репрезентативной выборке, учитывающей региональную представительность, формы и направления подготовки. Это позволит определить совокупность факторов, определяющих положение студенческих семей и стратегии поведения молодых супругов, выявить типологические группы респондентов с точки зрения потребности в мерах поддержки.

Целью исследования является актуализация проблемы изучения семьи и социального положения студентов в истории России на примере советских студентов-востоковедов.
Методологическую базу исследования представляют общенаучные и специальные исторические методы исследования. К используемым научным методам относятся сравнительный, причинно-следственный и статистический анализ.
Результаты исследования. Доступные на сегодняшний день исторические источники позволяют начать восстановление исторической картины студенческой семьи и выявления связанных с ней проблем. Материалы из фондов дальневосточных архивов указывают на то, что в первой половине ХХ века большинство студентов-востоковедов во Владивостоке не имели семей, но в документах есть прямые и косвенные указания на состоявших в браке студентов и слушателей. На наличие семейных студентов указывают и их возрастные характеристики. Проблемы, связанные с семьей, не были актуальными для университета во Владивостоке, в отличие от проблем качества обучения или состояния здоровья. Власти и общество контролировали социальное происхождение и социальное положение студентов. В послевоенную эпоху ситуация изменилась. Пример московских вузов показывает, что в это время студенческие семьи стали обычным явлением. Семейные студенты имели некоторые преимущества.
Перспективы исследования заключаются в расширении источниковой базы для комплексного изучения студенческой семьи.
Associated parallels of the initial potential mineralization value of oral fluid and intensity of dental caries in children with cleft lip and palate
Authors: Ashurov Gayur G. , Ismoilov Abdurakhim A. 
Published: March 2022

BACKGROUND: Cleft upper lip and palate is the most common malformation of the maxillofacial region. Despite the huge successes that have been achieved by dental surgeons in eliminating such defects, the issues of studying the initial indicators of the cariesological status in children with congenital cleft lip and palate are still not fully resolved. The study of the above issues will allow us to correct the plan of therapeutic and preventive action, which will lead to effective rehabilitation of children with cleft lip and palate.
AIM: This study aimed to conduct a clinical assessment of the initial mineralizing ability of oral fluids in children with congenital cleft lip and palate depending on the cariology status.
MATERIAL AND METHODS: This study presented the results of the clinical assessment of the initial value of the mineralizing ability of oral fluid depending on the intensity of dental caries in children with congenital cleft lip and palate. To determine the mineralizing ability of mixed saliva, 76 teeth of pediatric volunteers with congenital cleft lip and palate with a high level of mineralization potential of oral fluid, with medium, low, and very low levels of the studied indicator, were examined. The level of the mineralizing ability of mixed saliva was determined by visualization depending on the involvement of functionally oriented groups of teeth with caries.
RESULTS: The general characteristics of the mineralization potential of oral fluids, depending on the intensity of dental caries, help determine that with mild caries, the average value of the studied indicator was 21.9%, at an average intensity level of 31.0%, at a high intensity level of 47.1%.
CONCLUSIONS: An inverse-diameter dependence was found in the intensity level of caries on the mineralizing ability of oral fluids.

Perturbative-Integro-Differential Solution for the Nonlinear Hydraulic Diffusivity Equation for Infinite-Acting-Oil Flow in a Permeability-Pressure-Sensitive Reservoir
Authors: Fernandes Fernando Bastos 
Published: March 2022

Summary
The nonlinear hydraulic diffusivity equation (NHDE) models the isothermal single-phase Darcian flow through porous media considering the variation in the properties of the rock and the fluid present inside its pores. Typically, the dimensionless solution of the linear hydraulic diffusivity equation (LHDE) pD⁢(rD,tD) for constant permeability oil flow in porous media is computed through Laplace and Fourier transform or Boltzmann transformation. For these cases, the dimensionless general solution in cylindrical coordinates is expressed by the transcendental function exponential integral Ei(rD,tD).
This work develops analytically a new coupled perturbative-integro-differential model to solve the NHDE for oil flow in a permeability-pressure-sensitive reservoir with source. The general solution is computed combining a first-order asymptotic series expansion, Green’s functions (GF), and a Volterra’s second kind integro-differential formulation. A set of pore pressure and permeability values for two sandstones samples in an offshore reservoir from Brazil is obtained experimentally using the geomechanical elastic parameters (e.g., the Young’s modulus and Poisson’s ratio in addition to a uniaxial cell). These data are used as input in the computational code to run the analytical model and evaluate the reservoir permeability change. After these data input, the model runs and it allows to compute the instantaneous reservoir permeability values over the well-reservoir life cycle. The model calibration is performed by comparing the developed solution with a numerical porous media oil flow simulator named IMEX®, widely used in reservoir engineering and well-testing field operations and scientific works. The general solution of the NHDE mD(rD,tD) is computed by the sum of the linear solution pD(rD,tD) (constant permeability) and the first-order term of the asymptotic series expansion mD(1)(rD,tD), composed of the nonlinearity present in solution caused by the reservoir permeability variation. The results have shown that the developed solution is accurate, when compared to the numerical simulator, providing to be an attractive mathematical tool to help the well-reservoir management due to its low computational costs, when compared to the numerical simulators acquisition costs.
A Novel Foam Flooding for Enhanced Oil Recovery in Fractured Low-Permeability Reservoirs: Performance Evaluation and Mechanism Study
Authors: Li Xu , Chen Xin , Xu Zhenhua , Pu Chunsheng 
Published: March 2022

Summary
Foam flooding is an effective enhanced oil recovery (EOR) technology and has been widely applied in conventional reservoirs. However, its application in fractured low-permeability reservoirs is rarely reported. Hence, this study has conducted a series of laboratory experiments to investigate the application potential of foam flooding and clarify its EOR mechanism in fractured low-permeability reservoirs. Based on reservoir conditions, our laboratory has developed a novel foam system consisting of nano-SiO2 particles, water-soluble thixotropic polymer (WTP), and sodium dodecyl benzene sulfonate (SDBS). With the aid of nuclear magnetic resonance (NMR) technology, it was found that the foam flooding can significantly enhance the oil recovery in fractured low-permeability cores. The injected novel foams can plug the cracks in core samples and improve the imbibition in nanopores. As a result, more oil would be displaced from the nanopores and micropores. In addition, the foaming agent in the bulk solution can moderately reduce the oil-water interfacial tension (IFT) and alter the wettability of rock surface, improving the flowability of oil and the imbibition effect. Most importantly, the field tests in Ordos Basin have proved a promising EOR potential and appreciable financial rewards of the SDBS/nano-SiO2/WTP foam system applied in fractured low-permeability reservoirs.
Mucosal Injection as treatment for rectal prolapse in children with corrected anorectal malformation
Authors: Murphy Frederike , Märzheuser Stefanie 
Published: March 2022

Abstract
BackgroundThe aim of this study was to explore anal mucosal injection of bulking agents as treatment for rectal prolapse in patients with corrected anorectal malformations. To our knowledge, no prior research has been published on this matter.Despite rectal prolapse being a common occurrence, treatment is poorly standardized due to a small number of cases and the pathogenesis of rectal prolapse differing from that in healthy populations, often rendering usual treatments unsuccessful. Materials and MethodsWe used bulking agents usually used in endoscopic treatment of vesicoureteral reflux (Deflux, Vantris) to treat rectal prolapse in children with corrected anorectal malformations. We retrospectively analyzed pre- and intraoperative characteristics and postoperative outcomes. Patients were recruited from our consultancy for patients with anorectal malformations.Results16 children were included. Average operating time was 31 minutes.No intraoperative complications were recorded. Two patients showed minor bleeding, which ceased without further surgical interventions. Three patients developed local erythema/infection, which improved under a short course of antibiotics. Follow up ranged between 6 weeks and 76 months. One patient showed partial recurrence. No further complications were recorded.ConclusionsMucosal injection of bulking agents is a safe, minimally invasive and feasible treatment for rectal prolapse in this patient collective. In the absence of major complications, surgery time and length of hospital stay proved to be short. Further studies with larger samples, long-term follow up and direct comparison with alternative treatments should be conducted to explore this opportunity further and optimize treatment.
