Published: September 2022

With the rapid development of the Internet, GSM (Global System for Mobile Communications) is gradually developing towards “centralization, standardization, informationization, and refinement”. Since 2011, China has carried out smart city construction projects and awarded nearly 200 cities as pilot cities for smart cities. Smart cities gradually begin to expand and build, and with it comes the generation of a large amount of smart city public information. It is urgent to realize the rational mining and analysis of information, and it is urgent to provide practical solutions to solve the practical problems faced by smart cities. Smart city management and services. This paper constructs a smart city public information mining system based on GSM wireless network. The system is independent of the mobile network. By migrating computing and storage capabilities and business service capabilities to the edge of the network, applications, services, and content can be localized and distributed in close proximity. The deployment and development prospects are broad. A smart city video network service platform based on mobile edge computing, relying on edge computing technology, introduces GSM offload gateways in the deployment, reconstructs mobile networks, uses 5G edge computing capabilities to calculate videos, stores and forwards them to the edge computer processing space, changing the mobile network Economic form. In addition to the task scheduling problem of the system environment in this paper, a distributed multi-user computing task scheduling algorithm with the goal of achieving Nash equilibrium is proposed. Game theory and mathematical derivation are used to prove that the system overhead has an upper limit of convergence and to quantify several efficiency factors for centralized optimization performance. The system makes full use of part of the existing mobile network resources, combines traditional network optimization technology with advanced information mining and analysis tools, has complete information management capabilities, and guarantees the service quality of the entire smart city public information platform.

The objective of this study was to evaluate the prevalence and diversity of Enterococcus spp. and antibiotic-resistant Enterococcus faecalis and Enterococcus faecium isolates in different foods worldwide. This study used meta-analytical methods. Besides, Web of Science (n= 705), Medline (n= 6), and Scopus (n= 1338) were searched for studies in the years 1995–2021 using related keywords. Results showed that the pooled prevalence for Enterococcus spp. and antibiotic-resistance of E. faecalis and E. faecium isolates were 0.41 (95% C.I. 0.34–0.47), 0.25 (95% C.I. 0.13–0.38), respectively. According to the results of the subgroup analysis, the lowest and highest prevalence of Enterococcus spp. in food types were calculated for red meat (0.56), and fermented foods (0.29). Also, as a result of subgroup analyses by country the highest prevalence of Enterococcus spp. was calculated in studies conducted in Slovakia (0.74). In contrast, the lowest prevalence was calculated in studies conducted in Georgia (0.07). The meta-analyses improved our understanding of the prevalence of Enterococcus spp. and the antibiotic resistance of E. faecalis and E. faecium isolates in different foods and provided results that can be useful as input for quantitative microbiological risk evaluation modeling.

Authors: Pszczółkowska Beata , Bijok Michał , Brzozowska Beata
Published: September 2022

Introduction: The aim of this work was to study the influence of the applicators used for cervical cancer patients treated with high dose-rate brachytherapy (HDR-BT) in the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland on doses in the tumour volumes and organs at risk.

Material and methods: The treatment was carried out using Iridium-192 in 4 fractions (7.5 Gy each) given in weekly intervals. Two types of applicators were used for comparison: fletcher and ring. The standard dose distribution parameters, read from the system Oncentra Brachy (version 4.5, Elekta), for bladder, rectum, and sigmoid (D2 cc) and tumour (HRCTV D100, D98, D90) were studied. Patients were divided into two groups (240 treatment plans) depending on the type of applicator used and into four groups according to the tumour volumes (HR-CTV < 25 cm3 or HR-CTV ≥ 25 cm3). The collected data were analysed using the PQStatSoftware (version 1.8.2).

Results: The treatment plans prepared with all types of applicators fulfil the dose distribution requirements, however, the dose delivered to the tumour using the ring applicator was found to be the highest. For the bladder and sigmoid the optimal dose distribution was obtained when using the fletcher applicator, while for the rectum the ring applicator gave the smallest dose value. The D2 cc parameter for sigmoid obtained for fletcher treatment has smaller values in the case of patients with small tumour volume and for this type of applicator was observed a statistically significant difference when compared with the ring.

Conclusions: The ring applicator gives the optimal parameters of the dose distribution independently on the tumour volume with respect to the fletcher applicator, which is however more often used in clinical practice.

Authors: Ounoughi Nabil , Dribi Yamina , Boukhellout Abdelmalek , Kharfi Faycal
Published: September 2022

Introduction: Oxygen (16O) ion beams have been recommended for cancer treatment due to its physical Bragg curve feature and biological property. The goal of this research is to use Monte Carlo simulation to analyze the physical features of the 16O Bragg curve in water and tissue.

Material and methods: In order to determine the benefits and drawbacks of ion beam therapy, Monte Carlo simulation (PHITS code) was used to investigate the interaction and dose deposition properties of oxygen ions beam in water and human tissue medium. A benchmark study for the depth–dose distribution of a 16O ion beam in a water phantom was established using the PHITS code. Bragg’s peak location of 16O ions in water was simulated using the effect of water’s mean ionization potential. The contribution of secondary particles produced by nuclear fragmentation to the total dose has been calculated. The depth and radial dose profiles of 16O, 12C, 4He, and 1H beams were compared.

Results: It was shown that PHITS accurately reproduces the measured Bragg curves. The mean ionization potential of water was estimated. It has been found that secondary particles contribute 10% behind the Bragg peak for 16O energy of 300 MeV/u. The comparison of the depth and radial dose profiles of 16O, 12C, 4He, and 1H beams, shows clearly, that the oxygen beam has the greater deposited dose at Bragg peak and the minor lateral deflection.

Conclusions: The combination of these physical characteristics with radio-biological ones in the case of resistant organs located behind the tumor volume, leads to the conclusion that the 16O ion beams can be used to treat deep-seated hypoxic tumors.
Psychomotor Abilities as Predictors of Actions of Handball Goalkeepers During Saves
Authors: Krawczyk Paweł , Bodasiński Sławomir
Published: September 2022

Introduction.
The aim of this study was to determine whether the level of selected psychomotor abilities is a predictor of goalkeepers’ actions performed when saving throws made by the attacker in and without contact with the defender depending on the court area from which the throws are made.

Material and Methods.
The study included ten leading goalkeepers of the Polish PGNiG Superleague. The research material was a video recording of 1369 goalkeeper saves during throws without contact between the attacking player and the defender and 898 with contact. To assess goalkeepers’ actions, the observation method categorized according to Norkowski’s concept was used. The level of selected psychomotor abilities was assessed using the Vienna Test System. RT (ver.S.1) – simple reaction time, RT (ver.S.3) – reaction time with choice; ZBA (ver.S.3) – time-space anticipation. The statistical test used was the regression analysis.

Results.
The research results presented indicate that selected psychomotor abilities are the predictors of goalkeepers’ actions in the context of the court area from which a throw is made depending on the contact between the thrower and the defender. Predictors of the effectiveness of interventions during throws from pivot positions (without contact with the defender) are simple reaction time, motor time and time anticipation (y = 0.40326RTSRT - 0.66451MTSRT - 0.62533TA - 0.18835RTCRT + 69.58). The predictor of the effectiveness of interventions during throws from backcourt position from the first line (without contact with the defender) is reaction time with choice (y = -0.15796RTCRT + 70.92).

Conclusions.
Specific psychomotor abilities should be developed to increase goalkeepers’ effective actions and reduce errors that result in ineffective saves, i.e. the loss of goals.

Published: September 2022

The aim of the present study was to examine the antitumor and toxicity effects of ruthenium(II) complexes, [Ru(Cltpy)(en)Cl][Cl] (Ru-1) and [Ru(Cl-tpy)(dach)Cl][Cl] (Ru-2) on heterotopic murine colon carcinoma model.

For tumor induction, 1×106 CT26 cells suspended in 100 μl of DMEM were injected subcutaneously into flank of male BALB/c mice. Treatment groups were as follows: Ru-1, Ru-2, oxaliplatin and control (saline). The intraperitoneal administration of the tested complexes began on 6th day after CT26 cells inoculation. Each complex was administered at dose of 5 mg/kg, twice weekly, four doses in total. To assess toxicity, serum values of urea, creatinine, AST and ALT were determined and histopathological analysis of organs and tumor were performed. In order to assess the effects of Ru(II) complexes on markers of oxidative stress and antioxidant defense system, we determined the TBARS, GSH, SOD and CAT in the homogenate of tumor, heart, liver, lungs and kidney tissues.

The findings indicate that Ru-1 and Ru-2 exerts equal or better antitumor activity in comparison with oxaliplatin, but with pronounced toxic effects such as reduced survival rate, cardiotoxicity, nephrotoxicity and hepatotoxicity. The increased index of lipid peroxidation in the tissues of the kidneys and heart, but decreased in tumor tissue, after Ru(II) complexes administration, indicates the importance of the induction of oxidative stress as a possible mechanism of nephrotoxicity and cardiotoxicity, but not the mechanism by which they realize antitumor activity.

Additional studies are needed to elucidate the mechanism of antitumor activity and toxicity of the Ru(II) complexes.

Published: September 2022

Until the 13th Party Congress, the term/concept of "Social development management" has been increasingly perfected in terms of both content and policy and management implications. Nevertheless, the process of advocacy, development and practical manifestation of "development management" in Vietnamese social life is taking place rapidly. How does that process happen, especially in the context of national digital transformation? The relationship between social development management and digital transformation needs to be studied, supplemented and perfected from real life.

From a macro perspective (considering national development orientations) and given document analysis (Party guidelines, State policies), the purpose of the article is to provide connotation of development management and social development in the new period (context of digital transformation ) in a wide range of aspects such as basic characteristics or content of the undertakings and policies. In doing so, it hopes to contribute to a better understanding of the term/concept of “social development management/governance".

Influence of Temperature and Pressure on the Lattice Constant of SrTiO3 Perovskite by the Statistical Moment Method with Improved Interatomic Potential
Authors: Phuong Cao Huy , Hung Vu Van
Published: September 2022

Temperature and pressure dependence of lattice constants of a cubic Strontium Titanate (SrTiO3) has been investigated using the statistical moment method. The lattice constants at various temperatures is derived in closed analytic form by including the anharmonic effects of the lattice vibrations explicitly. The potential with the partial charge model and Morse function is used. The numerical lattice constants at high temperatures by the statistical moment method are in good and reasonable agreement with the other theories and the experimental data. Variations of the lattice parameter of SrTiO3 with the temperature are obtained at 1 atm, 8.2 GPa, and 15.2 GPa.  Increasing of the lattice constants with increasing temperature is due to enhancing atomic anharmonic fluctuations in SrTiO3 lattice crystal at higher temperature. A decrease of the lattice constants with increasing pressure can be demonstrated by the reduction of atomic vibrations in SrTiO3 crystal lattice at higher pressures.
Calculation of the Dynamic Responses of Rails Subjected to Moving Loads on Ballasted Railway Track
Authors: Le Hung Tran , Dinh Duc Nguyen
Published: September 2022

The dynamical responses of railway track has been carried out by different ways. In this work, by developing an analytical model for the ballasted railway track which includes two rails connected to the railway sleeper, a fast method to calculated the dynamic responses of the two rails is presented. The rail is modelled as the infinite beams posed on the periodically supports which are rested on a viscoelastic foundation. We consider the dynamic equation in the steady-state of rails subjected to the moving loads. By using Fourier transform together the periodically conditions, a relation between the reaction force and the beam displacement in the frequency domain has been demonstrated. Then, by performing this relation into the dynamic equation of sleeper laying on viscoelastic foundation, the dynamic responses of the two rails can be obtained with a help of Green’s function. The numerical example demonstrates the effect of the support on the beam responses.

We have built the research model of the dual resonant frame parameter generator based on the actual circuit diagram implemented in the laboratory to evaluate the mechanism of the dual resonant frame, two-frequency generator. The dual resonant frame parameter oscillator produces the desired frequency w2 which depends on the pump frequency and frequency w1. On the basis of the research model, we have successfully tested the mechanism of the dual-frequency transmitter, which makes it possible to manufacture RF oscillators with low phase noise, thereby improving stability. The output frequency stability w2 depends on the stability of the pump frequency and the frequency w1.

A molecular dynamics (MD) simulation has been carried out to explore the microstructure and diffusion pathway in amorphous vanadium pentoxide (V2O5) materials at room temperature and ambient pressure. We showed that the simulated model is a mix of basic units VO5 and VO6 connected to each other via 2 or 3 bridging oxygens. In the simulated model, there exist regions without atoms (cavity) in the form of clusters or channels. We found that 87% large pores, larger than or equal to oxygen atoms, overlap to form the largest tube.

PREVISÕES ENTRE OS ADVENTISTAS AO LONGO DOS TEMPOS: O CONTEXTO DE MARCAÇÃO DE DATAS PARA VOLTA DE JESUS
Authors: Tadeu Xavier Érico
Published: September 2022

As previsões em torno da segunda volta de Jesus no contexto adventista ocorreram desde o início do movimento millerita. Neste trabalho são apresentadas as marcações de datas e o contexto em que estas ocorreram entre os primeiros adventistas e os adventistas do sétimo dia atuais. Na perspectiva de compreender esse contexto, este artigo se propõe a apresentar um pouco da história adventista a respeito da marcação de datas para o retorno de Cristo tendo em vista demonstrar o posicionamento da Igreja Adventista do Sétimo Dia sobre essas marcações. Utiliza-se o método histórico-bibliográfico para atender ao objetivo proposto. Analisando o contexto histórico do movimento millerita observa-se que a marcação de datas para o retorno de Cristo, inicialmente, derivou dos estudos das profecias dos tempos escrita por Daniel e afirmada em Apocalipse, que gira em torno do cumprimento dos 2.300 dias previstos para a purificação do Santuário. E se conclui que alguns adventistas, desde o início e ainda hoje continuam a fazer previsões sobre a volta de Cristo e o fim dos tempos independentemente do posicionamento da Igreja Adventista do Sétimo Dia como instituição.

Published: September 2022

This article presents a descriptive approach whose objective is to explain theological models present in academic publications (theses and dissertations). It is not intended to be a systematic analysis or even a hermeneutic-exegetical study, but rather a narrative approach to the theologies present in the consulted material. This is a narrative review of the literature, and the steps for elaboration and organization derived from other studies. It was operationalized according to the following steps: identification of the theme, bibliographic survey, selection of texts, annotations, preliminary structuring and logical structuring of the study. We sought to provide an understanding of current knowledge on the theme “hospital chaplaincy”, highlighting possible gaps and suggesting an agenda of investigations to be undertaken. The TQO strategy (theme, qualifier, object) was used to formulate the research question, which is indicated for narrative reviews, resulting in the issue: which theological models are present in theses and dissertations available in the Brazilian context? The searches were online in the theses and dissertations database of the Coordination for the Improvement of Higher Education Personnel (Capes), carried out in 2020, using the descriptor “chapel*/hospital chaplaincy”, without restrictions on the year of publication or any other. The titles of interest related to the theme were included, in order to answer the proposed question. Data were organized in tables, with qualitative and quantitative summaries. Thirteen productions were retrieved. Among the main results, it is highlighted that approaches of anthropological and praxiological origin prevailed, associated with theological models/concepts such as “imago Dei”, “poimenics” and “theodicy”.

Objetivo: Compreender a visão dos estudantes de medicina sobre os cuidados paliativos. Revisão bibliográfica: A forma com que o estudante de medicina lida com a morte está ligada a diversos fatores de modo integral, de acordo com as experiências vividas por cada indivíduo ao longo da sua vida. Além disso, ao longo da sua jornada de trabalho, o processo de adoecimento e morte é um fator inevitável a todos pacientes, a capacidade de reconhecê-lo como natural se torna imprescindível pelo profissional. Esta carência de abordagem teórica acerca do tema impossibilita que os estudantes de medicina consigam manejar corretamente, tanto cognitiva, quanto emocionalmente, o paciente que esteja nos momentos finais de sua vida. Portanto, a introdução do tema ao longo do curso propicia com que a medicina seja individualizada a cada paciente de acordo com o seu modelo biopsicossocial e não apenas sob o panorama da doença propriamente dita. Considerações finais: Apesar de ser uma necessidade amplamente conhecida, a mudança necessária de cenário ainda não acontece no meio acadêmico, dessa forma estudantes de medicina em sua maioria não se sentem preparados para lidar com pacientes em estado terminal.
Spinal meningiomas in pediatric patients – A case series and literature review
Authors: Piątek Paula , Kwiatkowski Stanisław , Milczarek Olga
Published: September 2022

Background:

Meningiomas are the most frequent intracranial tumors in the adult population; however, they are rare in pediatric patients. In children, meningiomas often require further diagnosis of genetic comorbidities. As many as, 50% of young patients with meningiomas suffer from neurofibromatosis type 2 (NF2). Spinal meningiomas include only 10% of pediatric meningiomas.

Case Description:

Between 2000 and 2017, three children were hospitalized in the Neurosurgery Department. The patients reported prolonged periods of increasing neurological symptoms. In each case, a total gross tumor resection was performed. Histopathology result in each patient was meningioma psammomatosum. Only one girl required adjuvant radiotherapy (RTH) due to recurrent tumors. Magnetic resonance imaging (MRI) showed spinal nerves schwannomas and bilateral vestibular schwannomas in two patients with NF2.

Conclusion:

A slow tumor growth is characteristic of spinal meningiomas. Back pain is a frequent initial symptom of a slowly growing tumor mass. Subsequently, neurological deficits gradually increase. Patients require a long follow-up period and control MRI-scan. Children with diagnosed spinal meningioma should be strictly controlled because of the high risk of their developing other tumors associated with NF2. Surgical resection is the primary treatment modality of meningiomas. Adjuvant RTH should be recommended only for selected patients.
Calvarial metastasis from malignant pheochromocytoma associated with multiple endocrine neoplasia
Authors: Hernandez Mary Angeline Luz Ubias , Khu Kathleen Joy O
Published: September 2022

Background:

Malignant pheochromocytoma is a rare neuroendocrine tumor that may metastasize to the bones, liver, lungs, kidneys, and lymph nodes. Cerebral and skull metastases are even rarer, with only 17 cases reported in the literature. To the best of the authors’ knowledge, this is the first reported case of a purely calvarial metastasis from malignant pheochromocytoma associated with multiple endocrine neoplasia type 2A (MEN2A).

Case Description:

A 31-year-old Filipino man diagnosed with MEN2A was found to have elevated urine metanephrine on routine surveillance, and workup revealed right adrenal and hepatic masses and a focus of intense tracer accumulation on the right frontal bone on metaiodobenzylguanidine I-123 scan. All the newly discovered lesions were resected to achieve tumor control. Histopathology revealed a diagnosis of pheochromocytoma for the calvarial lesion.

Conclusion:

Malignant pheochromocytoma may give rise to indolent metastatic foci that can easily be missed without a thorough examination. Misdiagnosis and delays in management of this disease can be detrimental, resulting in irreversible complications and death.

Penelitian ini bertujuan untuk mencari pola ketersediaan pangan dan gizi makro yang menentukan prevalensi stunting di 23 negara Asia dalam 3 kawasan.
Metode, Desain penelitian studi ekologi dengan menggunakan data sekunder dari Food Balances Sheet dari Badan Pangan FAO yang diunduh melalui internet.
Hasil, Ketersediaan energi, protein, dan lemak di Asia Tenggara dan Asia Selatan lebih rendah dibandingkan Asia Barat yang mempunyai prevalensi stunting <15%. Semakin rendah ketersediaan gizi makro semakin tinggi prevalensi stunting.
Kesimpulan, Ketersediaan pangan dan gizi makro yang mendekati proporsi pola konsumsi sehat merupakan pemungkin lingkungan bagi penurunan stunting.
HACIA UNA HISTORIA DE LAS TENDENCIAS TROTSKISTAS DESPUÉS DE TROTSKY
Authors: Gaido Daniel
Published: September 2022

La historia de las tendencias trotskistas después de Trotsky sigue siendo, más de 80 años después de la muerte de Trotsky, en gran parte terra incognita o, más exactamente, un bazar para que todo tipo de sectas vendan sus mitos. Solo de vez en cuando surge una obra que saca la historia del trotskismo del ámbito de la mitología y nos proporciona los elementos que necesitamos para reconstruir la experiencia real de los militantes trotskistas en un tiempo y lugar determinados. En este sentido, esta breve obra no tiene otro propósito que brindar un panorama general de experiencias internacionales vinculadas al trotskismo de la segunda mitad del siglo XX a fin de avanzar en una comprensión circunstanciada de su historia y desarrollo.
Case Study and Patient Counseling for Elderly Patient on Psoriasis Vulgaris
Authors: Ch. Sri Lakshmi Mallika
Published: September 2022

The origin is characterised by skin and nail spots. It is considered a serious skin condition that affects around 100 million people worldwide. In 2016 - 2017, around 2% of the global population and 0.44-2.8% of the Indian population were affected  with psoriasis. The five most common kinds of psoriasis are plaque, guttate, inverted, pustular, and erythrodermic. Plaque psoriasis, also known as psoriasis vulgaris, is the most prevalent type of illness (about 90% of cases) and is characterised by  red patches covered with white scales. A 75-year male case with raised lesions on both legs from 6 months with fever arrived at the hospital on 03-MAR-2022. He had a history of raised scaly lesions on both the legs, trunk and upper limbs for 6  months. Multiple hyperpigmented scaly plaques of varying sizes on a trunk, back, both upper limbs, and huge plaques on both the lower limbs. Due to psoriasis, young adults with relatively stable plaque psoriasis experience feelings of embarrassment, impairments in daily activities, deteriorating physical health and decreased work productivity. Female patients, those with a high BMI, and those with a longer duration of illness appeared to be more severely impaired. The  observations suggest that the clinical patterns and pathogenesis of psoriasis in the elderly may differ from those in the middle-aged onset group. To fully understand psoriasis that occurs in this age group, additional epidemiological and genetic  research is required.

Published: September 2022

This study aimed to perform an in vitro assessment of probiotic properties and to select
lactic acid bacteria (LAB) strains that can produce the bioactive compound, gammaaminobutyric acid (GABA). A total of seven LAB strains of various species were
examined for probiotic properties. These strains produced antimicrobial substances to
inhibit the growth of target pathogenic bacteria. All selected LAB strains could withstand
GI tract conditions. The strains showed bile salt hydrolase (BSH) activities. An antibiotic
susceptibility test revealed that all examined strains were susceptible to ampicillin,
chloramphenicol, erythromycin, gentamycin, penicillin and tetracycline, whereas they
were resistant to kanamycin, norfloxacin, streptomycin and vancomycin. All strains of
LAB in the current study gave high adhesion to Caco-2 cells ranging from 23.32-75.48%.
Moreover, all tested LAB cells could inhibit Salmonella enterica serovar Enteritidis
invasion of Caco-2 cells. Additionally, the tested LAB cells and cell-free supernatants
(CFS) showed low cytotoxicity to inhibit the proliferation of Caco-2 cells. Moreover,
three LAB strains, L. curvatus FJNP12, L. plantarum SKKL1 and W. cibaria SFM5,
clearly showed GABA production based on the TLC results. Additionally, these strains
also yielded high amounts of GABA according to an HPLC method, 15.66, 11.76 and 5.62
g/L, respectively. The open reading frame (ORF) of the gadB gene of L. plantarum
SKKL1 revealed that it was 1,407 bp in length, encoding a polypeptide of 469 amino
acids, with a molecular weight of 53.56 kDa and an isoelectric point (pI) of 5.58 predicted
using the ExPASy program. These strains could be used in starter cultures for value-added
agricultural products.
