Introduction. In recent years, there has been a persistent trend towards an increase in the incidence of urolithiasis. The treatment of large and complex kidney stones greatest difficulty is one of the challenges. Such stones, as well as surgical methods of their removal, can have an adverse effect on the functional state of the kidneys, which confers a significant medical, social and economic problem. The purpose of this study is to identify factors affecting the functional state of the kidneys in the postoperative period when using various video endoscopic methods of surgical treatment of patients with large and complex kidney stones. Materials and methods. We analyzed the results of treatment of 97 patients with large and complex kidney stones. Depending on the treatment, all these patients were divided into three groups: 1st – 44 (45,36%) patients who underwent percutaneous nephrolithotripsy in prone position, 2nd – 29 (29,9%) patients who underwent percutaneous nephrolithotripsy in the supine position, 3rd – 24 (24,74%) of the patient who underwent pyelolithotomy with laparoscopic and retroperitoneoscopic approaches. Assessment of the area and density of stones was performed by computed tomography. The glomerular filtration rate (GFR) was calculated by CKD-PI formula and dynamic nephroscintigraphy was used to assess of each kidney function. Results. In the postoperative period, the decrease in GFR was most pronounced in the group of patients after percutaneous nephrolithotripsy in the supine position. Among the most significant factors worsening this indicator were the volume of intraoperative (r=0,410, p<0,001, n=97) and postoperative blood loss (r=0,294, p <0.01, n=97), duration of surgery (r=0,187, p <0,1, n=97), density (r=0,426, p <0,001, n=97) and the area (r=0,554, p <0,001, n=97) of the concretion, as well as the body mass index (r=0,294, p <0,01, n=97). Conclusions. The most significant factors that have a negative impact on the functional state of the kidneys were the density and area of the stone, the patient's body mass index and the volume of intraoperative blood loss. The least deterioration of kidney function in the postoperative period was observed with endoscopic pyelolithotomy, and the greatest – with percutaneous nephrolithotripsy in the patient's back position.

Authors: M Ahmadi  , A Al Nakash
Published: May 2022

This review article discusses the current modern management of adenomyosis. Adenomyosis is common amongst women of child bearing age and it has many implications on quality of life. These women struggle with symptoms of dysmenorrhoea, menorrhagia and infertility. We discuss the medical, interventional and surgical management of adenomyosis. There are numerous medical treatments which involve hormonal and non-hormonal methods. The interventional methods consist of High intensity focus ultrasound (HIFU), percutaneous microwave ablation (PWMA) and radiofrequency ablation (RA). This paper also discusses the role of surgical technique and whether it has a role in the management of adenomyosis, currently surgical options are not routinely offered to patients. There have been promising studies which have identified that surgery has improved fertility, menorrhagia and dysmenorrhea for patients with adenomyosis.

Introduction: Conditions within prisons and high human traffic fuels spread of outbreaks within prisons. Security and ethical-legal dilemma complicates patient management in prisons. Purpose: Assess treatment and isolation outcomes of patients admitted in the prison treatment units. Methods: Cross-sectional and cohort retrospective designs were adopted. All those who tested positive were recruited. Top officials and healthcare workers seconded to prison treatment center were respectively identified for key informant interviews and focused group discussions. Data collection: Data on treatment outcomes was abstracted from medical records while data on staff perception was collected using focused group discussions and key informant interviews. Data analysis: Data was managed in R version R-4.0.3 and both descriptive and inferential statistics were used, summaries were presented in frequency tables and graphs. Results: 117 patients had been admitted into the treatment unit with all being males save for one female. The average length of stay was 18 days. There was an inverse correlation between age and length of stay. (-0.1092). There was observed reduced security risks and cross-infection amongst prison wardens compared to when prisoners were being transferred to the general treatment units. Discussion: Improved patients outcomes with reduced risks of cross-infections amongst prisoners, staffs and staffs to family members enhanced confidence of health care workers. Ethical and legal dilemmas of detaining rumandees released on cash-bail remained a key challenge. Conclusion: Management of outbreaks within prison settings has more benefits compared to when inmate patients are transferred to general treatment centers. Recommendation: Benefits of managing outbreaks within areas of confinement outweighs risks of otherwise. Thus we recommend management of similar cases within prisons.

Published: May 2022

Oxidative stress has been implicated in the initiation and progression of a plethora of diseases including atherosclerosis, diabetes mellitus, rheumatoid arthritis, neurodegenerative diseases, cardiovascular diseases and cancer. Due to the toxic and mutagenic side effects of some synthetic antioxidant compounds, intense interest is recently converged on natural antioxidants. This study therefore aimed at evaluating the antioxidant potential of essential oil extracted from Phoenix dactylifera seed. Phoenix dactylifera seed essential oil (PDEO) was extracted via steam-distillation technique. The antioxidant activity of the essential oil was assessed by radical scavenging, lipid peroxidation and reduction power assays. From the results obtained in this study, P. dactylifera essential oil showed significant concentration dependent antioxidant potential with maximum activity at 500 µg/ml viz: DPPH radical scavenging (76.24 ± 0.12 %), ABTS radical scavenging (68.97 ± 0.36 %), Nitric oxide radical scavenging (67.86 ± 0.16 %), Hydroxyl radical scavenging (68.70 ± 0.26 %), Fe2+ chelating ability (66.74 ± 0.25 %), Ferric reducing antioxidant power (262.29 ± 0.253 mMol FeSO4/g) and inhibition of lipid peroxidation (67.78 ± 0.29 %). Findings from this study revealed that essential oil from Phoenix dactylifera seed elicits substantial antioxidant activity and may serve as a veritable pharmacological candidate towards prevention of free radical related pathological damages.

Published: May 2022

This study identifies and examines drivers and barriers toward effective integrated and sustainable management and governance practices based on ecosystem services’ perspective of the Kurdistan Region of Iraq’s water management area. A combination of a systematic literature review and 28 individuals from Ankawa, Kasnazan, Haran City, Eskan, Bakhtiari, Tairawa, Mastufi, Khabat and Saiudawa were randomly interviewed. The decisions to use residents of these areas are based on their location as well as mixed challenges and conditions regarding water supply and use based on their social and economic statuses. The responses were analysed using NVivo 12 and the results of the study indicated that there have been substantial increases in environmental and ecosystem services awareness has been a key driver of heightening sustainability initiatives in the Kurdistan Region of Iraq. Additionally, the study reveals that lacking coherence between actors and sectors concerning natural resource governance is a major obstacle to undermining sustainable water management initiatives. It is inferred through the established findings that sound leadership, localized, decentralised management structures, and sustainable developments are pivotal for enhancing the water management efforts in the Kurdistan Region of Iraq. Moreover, local water suppliers, residents, farmers and decision-makers are encouraged to adopt additional and sound water monitoring practices to improve ecosystem services and valuable contributions toward improving human beings’ well-being.
Impact of external magnetic and Aharanov-Bohm (AB) Fields on the energy spectra of the Varshni-type potential in arbitrary dimensions
Authors: EB Ettah  , EE Iyeme
Published: May 2022

In this article, the Varshni potential is analyzed taking into consideration the effects of magnetic and AB flux fields within the non-relativistic regime using the Nikiforov-Uvarov-Functional Analysis method (NUFA) method. The energy equation and wave function of the system are obtained in close form. We find that the entirety of effects of these fields removes degeneracy as a consequence and raises the bound state energy of the system. More so, it could be deduced that to regulate the energy spectra of this system, the AB-flux and magnetic field will do so greatly. The results from this study can be applied in condensed matter physics, atomic and molecular physics.

Appendicitis is a pathology characterized by the obstruction of the lumen of the vermiform patient and is considered one of the first causes of acute abdomen that requires emergency surgery to avoid patient mortality, which is why two surgical management alternatives are used: open appendectomy and laparoscopic appendectomy. There are controversies about which is the best approach, but according to various studies it is reported that there is no significant evidence to say which is the best approach, however, it is also established that laparoscopy outperforms the open approach due to its better aesthetic result and less days of hospital stay in the postoperative period, there is less postoperative pain but greater surgical time and probability of residual abscesses in the laparoscopic group, with no difference in mortality in both groups, in addition to this it is reported that in patients approached by laparoscopy presenting a rapid return to daily activities and daily work, presenting a lower frequency of infections at the level of the surgical wound and also a lower rate of postoperative adhesions, with the consequent directly proportional decrease in postoperative complications such as, for example, occlusion by girlfriends and suture dehiscence’s.

Authors: Hilendarov A  , A Georgiev  , LT chervenkov
Published: May 2022

Introduction: Insulinomas are the most common category of pancreatic endocrine tumors, with an incidence of 1-7 cases per million people. Material and Methods: Most are intrapancreatic, benign and solitary. Therefore, they have an excellent prognosis after surgical resection. However, the localization diagnosis of insulinomas still poses a challenge to surgeons and radiologists. Results: We present two cases showing classical appearances on helical CT In these two cases the tumors were occult and could not be found by either abdominal enhanced spiral computed tomography (CT) or ultrasonography. We would like to emphasize the need for performing helical CT whenever the diagnosis is suspected, due to the ability to image the pancreas in the early arterial as well as in the equilibrium phase. Conclusions: We reminded of surgeons that insulinomas represent the most frequently found functioning endocrine tumors .Therefore, they have an excellent prognosis after surgical resection. However, the localization diagnosis of insulinomas still poses a challenge to surgeons and radiologists.

Asesmen Nasional Berbasis Komputer (ANBK) yang akan dilaksanakan di akhir tahun 2021 memberikan tantangan baru bagi dunia pendidikan. Tahap persiapan yang harus dilakukan oleh lembaga pendidikan terutama Sekolah Dasar menuntut adaptasi yang cepat dari semua komponen pendukung di dalam lingkup Sekolah Dasar. Mulai dari perencanaan sarana prasarana, pembiayaan, tenaga kependidikan yang bertugas sebagai teknisi, proktor, dan pengawas, sampai kepada mempersiapkan siswa untuk dapat mengikuti ANBK dengan protokol kesehatan. Penyediaan sarana prasarana ANBK bagi Sekolah Dasar menjadi tantangan besar karena tidak semua lokasi Sekolah Dasar dapat terjangkau internet dengan baik padahal pelaksanaan ANBK membutuhkan akses internet yang baik. Selain itu perangkat komputer yang harus disiapkan juga membutuhkan biaya yang tidak sedikit. Oleh karena itu banyak Sekolah Dasar yang menghadapi masalah dan kendala,sehingga Sekolah Dasar disarankan untuk melaksanakan ANBK dengan menumpang pada sekolah lain terdekat. Pelaksanaan ANBK dengan menumpang juga membutuhkan persiapan untuk mobilisasi siswa. Tahapan-tahapan yang harus dilakukan Sekolah Dasar dalam pelaksanaan ANBK tidak sedikit tetapi informasi detailnya baru bergulir pada pertengahan tahun 2021. Jadi banyak sekolah mengalami kendala dan kesulitan disamping tantangan jaringan listrik yang kadang tidak stabil.
Unexpected deformation processes in the rock mass in surface mining: Emergence factors and prevention capabilities
Authors: Usanov S.V. , Konovalova Yu.P. , Efremov E.Yu. , Kharisova О.D. , Usanova А.V.
Published: May 2022

Unexpected abnormal deformation processes in rock masses lead to disruptions in the operation of mining facilities and endanger human life and health. The studies show that physiographic conditions, physical and mechanical properties of rocks, features of structural and tectonic structure of the rock mass can influence the unexpected character of the deformation phenomena. One of the important parameters that determines the development of catastrophic deformation processes is the geodynamic activity of the rock mass, which forms its stress state. The purpose of the research is to develop methodological approaches to identification of potentially hazardous areas in the rock mass. To do this, experimental studies were carried out in a mine where unexpected abnormal deformations took place, and the role of influencing factors was analyzed. Experiments were performed using geological, geophysical and geodetic methods. As the result of the study, it was established that unexpected emergency deformation processes develop in areas where the maximum number of complicating factors is concentrated. A rating evaluation of the area of surface development has been developed based on a combination of factors affecting the stability of the rock mass. The developed approaches make it possible to diagnose the rock mass and identify areas where geomechanical processes develop according to special parameters. Area zoning can be the basis for the development of automated monitoring system of rock mass deformations to prevent unexpected emergency events.

Authors: Antoninova N.Yu. , Rybnikova L.S. , Slavikovskaya Yu.O. , Shubina L.A.
Published: May 2022

The article assesses available methods of managing mineral grades in mining and possible ways to improve the mining efficiency. Assessment criteria for the ore masses are given depending on mineral and chemical composition, structural and other features. The outcomes are presented of developing a methodology of zoning technological types of ores within an open pit with account of complex evaluation of qualitative characteristics of minerals using modern geoinformation technologies. Two main methods, i.e. express and detailed, are proposed for data interpretation in geoinformation systems, which require preliminary creation of a geological database and allow to make reliable assessment and zoning of ores within an open pit based on qualitative indicators. The methods are different in terms of labour intensity, level of detail and the possibility of adjusting the resulting models depending on established or changed requirements towards the mineral grade. An enhanced mining and geological information system allows zoning of technological types and grades of ores within an open-pit with a high degree of reliability, which contributes to the selection of the most effective ore treatment method as part of the ore grade management for specific mining and geological conditions at the planning stage of mining operations. Examples of zoning technological types of ores within an open pit as well as methodological approaches to selecting effective methods of ore grade management are presented for deteriorating mining and geological conditions of deposits and increasing requirements towards the quality of products.
The main factors affecting the convergence of calculated and actual values of deformations of existing buildings
Authors: Konyukhov D.S. , Kazachenko S.A.
Published: May 2022

A study of the interaction between an underground structure and the soil mass in which it is located is based on mathematical modelling by means of geotechnical software packages. Possible settlement of the foundations that support the foundations of buildings located within the influence area of underground construction is normally calculated with the PLAXIS software package. The actual settlements of these buildings when compared to the simulation results show differences in a wide range from 3 to 75%. Specific values are predetermined by the method of excavation support and the adopted technology of works. The paper analyses the ratio of actual and calculated (by different models, including the Coulomb-Mohr model and various modifications of the Hardening Soil Model as the most frequently used in our country and, therefore, analysed most thoroughly in respect of their advantages and drawbacks) deformations of existing buildings during underground works carried out in the vicinity. Factors influencing the deformations are considered. Numerical discrepancies for different methods and in different soils (sand, loam, clay) are given. Possible reasons for discrepancies are formulated. The deviations are strongly influenced by the adopted calculation scheme. A corresponding study on a detailed level required mathematical modelling, which was carried out using the example of excavation of a construction pit for the entrance hall of the Butyrskaya underground metro station in Moscow and a nearby building.

The article focuses on the issue of improving the efficiency of non-renewable and renewable sources of energy. It is shown that the problem still remains relevant. The key concept is that in order to develop new devices it is necessary to clarify the natural mechanism of electric current generation in the atomic-molecular structure of the current conductors. The aim of the work was to justify the physical phenomena of electric current generation and transport. The authors applied the Quantum theory to address theoretical issues, the results of which were confirmed by experimental studies. The principal differences shown between the various energy processes of electricity generation. Based on the analysis of the molecular structure of copper and the spherical electric field, a conclusion is made that there are no free electrons in the conductor. The hypothesis that the main phenomena of electric current formation occur at the level of electromagnetic energy emission by valence electrons of conductors is of scientific novelty. The electromagnetic energy induced in the magnetic field is the primary energy photon to be absorbed by the conductor electrons. It has been proven experimentally that the solar energy and thermal sources, which are electromagnetic energy with different emission frequencies, are identical. Application of the new knowledge can enhance the competence of the dedicated specialists and the efficiency of electrical energy generating devices.
Contracts versus relationship intention as indicator of customer trust in and commitment to cell phone service providers
Authors: Steyn Derik , Mostert Pierre
Published: May 2022

Social exchange theory postulates long-term customer-company relationships are built on trust and commitment. Cell phone service providers seek to secure the trust and commitment of their customers through service contracts. Relationship intention (RI) is a more precise measure of customer trust and commitment. This paper compares the trust of cell phone service customers and their commitment to cell phone service providers based on customers’ contract status and RI classification. Data from 1,473 cell phone customers from South Africa (n = 589) and the Philippines (n = 884) were analyzed. The study shows for both the South African and Philippine samples that there is no relationship between respondents’ contract status and their trust in or commitment to cell phone service providers and that trust in or commitment to cell phone service providers is significantly higher among high relationship intention (HRI) customers than among low relationship intention (LRI) customers. RI is a stronger indicator of customers’ trust in and commitment to cell phone service providers than contracts in both countries. This makes HRI customers more receptive to relationship marketing strategies than customers with contracts or LRI customers, as HRI customers trust and commit to cell phone service providers significantly more.
FORMAÇÃO EM PSICOPEDAGOGIA: UM ESTUDO COM DISCENTES E PEDAGOGOS EGRESSOS DA UNIVERSIDADE ESTADUAL DO PIAUÍ-UESPI
Authors: Mendes Chaves Barreto Maria dos Remédios
Published: May 2022

O curso de Pedagogia é, sem dúvida, um curso no qual se reflete sobre vários temas dentro desse âmbito educacional. Considerando a importância dos processos que envolvem a educação, tornase necessário o entendimento de algumas dimensões específicas, sobretudo quando nos remetemos a formação no ensino superior. Partindo dessa premissa, a psicopedagogia é um dos componentes fundamentais para a capacitação dos futuros pedagogos, visto que a partir de disciplinas e estágios é que os alunos serão estimulados a analisar, refletir e intervir na realidade dos educandos. Assim, o presente artigo visa refletir sobre algumas questões que envolvem a formação no ensino superior, a área de Psicopedagogia e a prática docente, a saber: Quem é esse profissional psicopedagogo (a)? Qual o seu campo de atuação? Qual deve ser a sua formação? Se o seu papel assume uma grande importância no contexto escolar, porque sua formação ainda é precária, sobretudo, nos cursos de Pedagogia? Essas questões norteadoras servirão de dispositivo para mobilização de uma discussão com vistas a responder nossos objetivos: Analisar as representações sociais de egressos do curso de Pedagogia da Universidade Estadual do Piauí - UESPI, sobre a formação docente na área da Psicopedagogia do referido curso; Descrever como os docentes do curso pesquisado vivenciam a formação em questão, através de suas práticas educativas; Avaliar a contribuição do curso de Pedagogia da UESPI para a constituição profissional do futuro psicopedagogo, na representação dos alunos egressos. Trata-se de uma pesquisa de abordagem qualitativa, elaborada através de pesquisa bibliográfica, descritiva e explicativa, utilizando a teoria das representações sociais em que as análises e os resultados foram apresentados por meio de reflexões dos discursos dos 9 entrevistados, através de entrevista semiestruturada, através da análise de conteúdo e subsidiados pela leitura de obras de autores que têm se dedicado a uma análise profunda dessa temática. Os resultados apontam que a maioria os sujeitos avaliam negativamente a formação acadêmica, pontuando que deveriam ter melhorias na ênfase da Psicopedagogia muito embora reconheçam o esforço docente na em promover um ensino mais inclusivo e significativo. No que se refere a avaliação da contribuição do curso de Pedagogia da UESPI para a constituição profissional do futuro psicopedagogo, na representação dos alunos egressos deixam a desejar quando não procuram investimentos, formação adequada e quando não propiciam uma mudança no sentido do curso ser mais completo em áreas específicas, como a Psicopedagogia.

Hasil yang ditemukan dalam penelitian ini menyatakan bahwa 12 kecamatan di Aceh Tamiang masih menggunakan tradisi Tepung Tawar dalam beberapa prosesi. Ada 4 kecamatan yang melakukan prosesi Tepung Tawar hanya pada kegiatan-kegiatan tertentu saja yaitu Kecamatan Banda Mulia, Sekerak, Seruway, dan Kecamatan Tamiang Hulu. Pada empat kecamatan tersebut, kegiatan revitalisasi tradisi Tepung Tawar dilakukan dengan berkoordinasi dengan Ketua MAA, tetua adat, dan tokoh masyarakat. Setelah dilakukan wawancara dan observasi didapatkan hasil bahwa proses revitalisasi tradisi Tepung Tawar dilakukan dengan lima cara yaitu (1) pengadaan lomba-lomba dalam masyarakat tentang tradisi Tepung Tawar, (2) melatih pemuda desa tentang prosesi Tepung Tawar, (3) menguatkan lembaga adat agar memperhatikan prosesi Tepung Tawar, (4) mengadakan lokakarya, dan (5) membuat buku saku tentang prosesi Tepung Tawar dalam masyarakat Aceh Tamiang. Upaya pemertahan tersebut harus dilakukan untuk mencegah degradasi dan kepunahan budaya di masa yang akan datang.

The phenomenon of delivering messages through mural art occurs in the social life of the Indonesian people, and is used as a medium for social criticism in the public sphere. The purpose of this study is to find the meaning of social criticism that is carried out through the media of mural art and to find the shift in values that occurs in mural art. Based on the research objectives, this research is a qualitative research with a structuralist-constructivism approach from Pierre Bourdieu.

The theories used to understand, criticize, find meaning and find shifts in the value of mural art are the Habitus Theory and the Cultural Production Theory. This study found that social criticism conveyed through the media of mural art has an economic meaning, a meaning of community popularity, and a meaning of freedom. While the shift that occurred, this study found that mural art, which was originally an artist's expression as a monumental work, shifted to a commodified and contemporary work.

Letter to the Editors of Psychological Science: Boosting Understanding is Unlikely to Correct False Beliefs About Most Science Domains: Regarding van Stekelenburg et al. (2021)

Van Stekelenburg and colleagues (2021) show that boosting understanding of scientific consensus reduces false beliefs about genetically modified foods (GMOs). Specifically, demonstrating the value of scientific consensus and providing information about scientific consensus on GMOs helps to correct misperceptions about GMOs being harmful. However, this technique is ineffective in reducing climate change misbeliefs. This is not surprising. We argue that the reported strategy, being a knowledge-based technique, has limited applicability to other contentious science domains. This is because misperceptions of such domains often do not involve poor science knowledge, but rather specific ideologies.
Children use common knowledge to solve coordination problems
Authors: Deutchman Paul
Published: May 2022

Recent work suggests that common knowledge is an important cognitive mechanism for coordinating prosocial behavior, in part because it reduces uncertainty about others’ cooperative behavior. However, it remains unclear whether children also rely on common knowledge to solve coordination problems. Here we examined whether 6-9-year-old children (N = 133) from the US were more likely to attempt to coordinate when they had common knowledge about a joint payoff. Participants saw three vignettes that modeled the structure of a two-player coordination problem and were provided with common knowledge, secondary knowledge, or private knowledge about the mutually beneficial, but risky, joint payoff. By 6-years of age, participants were more likely to attempt to coordinate when they had common knowledge than secondary knowledge, and secondary knowledge than private knowledge. Participants were also most likely to expect the other player to coordinate, and were most certain in their predictions, when there was common knowledge. Results indicate that, by middle childhood, children are able to solve coordination problems by relying on common knowledge, in part because it likely increases their certainty in others’ cooperative behavior. Overall, findings suggest that common knowledge is an important cognitive mechanism for coordinating behavior and that it does so by reducing uncertainty about others’ cooperative behavior.
