Meningkatkan literasi dan spiritual kepada anak-anak merupakan tanggung jawab bersama terutama keluarga dan gereja melalui pengajaran pendidikan agama Kristen. Seiring dengan perkembangan ilmu dan teknologi saat ini orang tua harus berupaya memberi layanan pendidikan kepada setiap anak. Dengan kata lain orang tua harus bertanggung jawab mengajar dan menyekolahkan anak-anaknya sampai kepada ke jenjang yang lebih tinggi. Tetapi dalam kenyataannya masih ada anak-anak yang belum menikmati layanan pendidikan sebagaimana mestinya, seperti anak-anak sekolah minggu yang ada di Pulau Teluk Nipah – Batam. Anak-anak yang ada di Pulau tersebut sebagian besar tidak bersekolah karena keterbatasan ekonomi kelurga serta jarak sekolah yang ditempuh cukup jauh dari rumah. Sasaran dalam program pengabdian ini adalah meningkatkan literasi dan spiritual anak-anak sekolah minggu di Pulau Teluk Nipah – Batam melalui penerapan metode pengajaran pendidikan Agama Kristen, sehingga anak-anak memiliki semangat dalam meningkatkan prestasi belajar untuk meraih masa depan yang lebih baik. Berdasarkan hasil pengamatan dan evaluasi terlihat anak-anak sekolah minggu dalam mengikuti kegiatan ini sangat antusias. Peningkatan literasi dan spiritual ini dilaksanakan selama 1 hari yaitu pada tanggal 22 Desember 2021 dengan jumlah peserta yang di rencanakan sebanyak 20 anak sekolah minggu. Setelah mengikuti kegiatan ini, anak-anak sekolah minggu dan orang tua memiliki pemahaman bahwa belajar dan sekolah itu sangat penting untuk masa depan anak.

Flautas de tubo complejo en Los Andes. Nuevos descubrimientos en la organología prehispánica
Authors: Pérez de Arce José
Published: March 2022

Las flautas con tubo complejo, capaces de dar un “sonido rajado”, son conocidas en diversas culturas prehispánicas entre el sur de Perú, el altiplano boliviano, el Noroeste Argentino y Chile Norte y Centro-Sur. Actualmente sólo se conocen entre los mapuches y los bailes chinos, en Chile, y su pasado arqueológico había sido analizado respecto a estas tradiciones vivas. En este artículo queremos entregar nueva información que permite ampliar este panorama hacia los Andes Centrales en tiempos prehispánicos. Se trata de flautas de cerámica correspondientes a diferentes tiempos y sistemas culturales. Estos hallazgos relativizan la diferencia, que hasta ahora hacíamos, entre flautas de un solo tubo (llamadas genéricamente ‘pifilkas’) y las de varios tubos (conocidas genéricamente como ‘antaras’). La interpretación de estos datos abre nuevas perspectivas al panorama sonoro de la región en el pasado, demostrando un gran refinamiento en torno a las propiedades tímbricas del sonido y su uso como parte de la cultura.

Gradiente de vulnerabilidad socio-ambiental en el Partido de Quilmes, Provincia de Buenos Aires, Argentina
Authors: Lacabana Pablo
Published: March 2022

El concepto de adaptación al cambio climático nos remite a posibles actuaciones emprendidas anticipadamente para reducir la vulnerabilidad de un sistema, de una ciudad o de un grupo social. Para generar capacidad adaptativa, es decir poder evitar pérdidas y acelerar la recuperación tras cualquier impacto climático, resulta fundamental, entre otras acciones, contar con información territorial. Detectar a tiempo las vulnerabilidades como fragmentaciones territoriales producidas por la desigualdad socio-ambiental, pueden hacer la diferencia para una eficiente gestión del riesgo. Es por ello, que este trabajo propone un análisis a partir de la propuesta de aplicación de un índice de vulnerabilidad socio-ambiental  para el partido de Quilmes con el propósito de obtener meta datos ambientales necesarios para posibles políticas de adaptación y resiliencia al cambio climático. De esta síntesis se desprende que en los radios censales en peor situación viven 19.749 habitantes en casi 14 km2 con 5.051 hogares. Mientras que los radios menos vulnerables tienen una población de 174.850 habitantes en un área de 24,53 km2 con 61.046 hogares. En el caso de los radios censales con una vulnerabilidad alta hay 115.792 habitantes de 30.122 hogares en 15,39 km2 y en los radios censales con vulnerabilidad media hay 128.495 habitantes de 35.865 hogares en 18,14 km2. A pesar de algunas limitaciones que presenta el índice termina siendo un buen indicador de la diversidad de situaciones sociales y ambientales presentes en Quilmes. Las variables con más peso son hogares no conectados a la red de cloacas, hogares con insuficiente calidad de servicios, hogares sin computadoras, hogares sin gas y hogares con insuficiente calidad constructiva. En los resultados de este estudio está presente la heterogeneidad social y ambiental, incluso dentro de las villas que son los lugares más afectados.

Evaluación de la vulnerabilidad socioecológica: estudio de caso en la Parroquia San Juan Cuenca, del río Chimborazo, Ecuador
Authors: Rosero Erazo Carlos Rolando
Published: March 2022

Los aspectos socioecológicos determinados por un conjunto de variables capturan la vulnerabilidad relativa y actúan como herramientas visuales para identificar aquellas zonas susceptibles a cambios socioambientales.Estos índices son de fácil uso e interpretación, además de ofrecer una orientación para la toma de decisiones políticas dentro de la jurisdicción local, en aspectos tanto económicos como cuestiones de conservación ymonitoreo de los ecosistemas. Las investigaciones más específicas, por otro lado, pueden generar planes para la reducción de riesgos en relación con las adversidades presentes en la zona. Este caso de estudio en particular, relaciona la vulnerabilidad socioecológica con respecto a la sequía como una amenaza, por lo tanto, este artículo busca inquirir, a través de la identificación de aspectos SES, la representación de cada variable, escala, dinámicas e interacciones producidas. El uso del análisis de componentes principales (PCA)como medio de agregación espacial e índices de vulnerabilidad normalizada contribuyeron a la comparativa de distribución espacial de datos, así mismo, se logró identificar características de agregación, más no de dispersión. La vulnerabilidad resultante, en consecuencia, indica la variabilidad de tres componentes únicos y estadísticamente independientes que proporcionan más información en cuanto al índice normalizado, el mismo que fue realizado mediante la suma de todas las variables o criterios SES. Esta herramientaproporciona información relativa de la vulnerabilidad socioecológica, siendo un resultado que subyace a los impactos socioecológicos formados por condiciones ambientales cambiantes en el tiempo, como el clima ycaracterísticas intrínsecas de la colectividad. La presente investigación tiene lugar en la Unidad Hidrográfica nivel 7 del río Chimborazo con 124 km² de extensión, la que se delimitó según el Manual de procedimientos de delimitación y codificación de unidades hidrográficas: Caso Ecuador (SUR UICN, 2009). Éste trabajo se realizó en un periodo de tres años desde el 1 de abril del 2017 al 31 de diciembre del 2020, para la obtención de datos de mayor fidelidad.
Del Crystal Palace a la Tour Eiffel. México en las Exposiciones Universales del Siglo XIX
Authors: Rodríguez Barba Fabiola
Published: March 2022

El propósito de este artículo es argumentar que la participación de México en las exposiciones universales del siglo XIX, puede ser considerada como el antecedente inmediato de lo que en el siglo XX se denominará diplomacia cultural. La evidencia encontrada es que México inició una tradición que repercutió hasta el día de hoy, en donde la proyección de su historia, así como la riqueza y diversidad de su producción artística y cultural fueron su carta de presentación que le permitiría ser apreciado y reconocido a nivel internacional. Con base en los testimonios de personajes que presenciaron esas exposiciones, así como documentos oficiales de la época se describen las características de esas exhibiciones. Para tal efecto, en este texto se expone la participación de México en tres de las más importantes del siglo XIX: la de 1851, la de 1889 y la de 1900. Esto nos permite comparar los distintos contextos en los que se decidió participar; y al mismo tiempo, esa selección nos posibilita observar la evolución de la narrativa exhibida por el gobierno mexicano en esos eventos. Con ello se pretende mostrar que las exposiciones universales fueron para México una oportunidad para darse a conocer y para promover una idea de país que se alineaba a los cánones de esa centuria: progreso, civilidad y paz.

Quantitative analysis of heat-source estimation of high-intensity focused ultrasound using thermal strain imaging
Authors: Obara Nozomi , Umemura Shin-ichiro , Yoshizawa Shin
Published: March 2022

For the clinical application of high-intensity focused ultrasound (HIFU), improvement in monitoring and guidance methods is necessary to enhance the treatment accuracy. Among the ultrasonic imaging techniques, thermal strain imaging has a potential to estimate temperature change based on the linear relationship between the thermally induced strain and temperature change via a tissue-dependent coefficient. In this study, the coefficient was experimentally measured and the temperature rise induced by the HIFU irradiation was estimated based on the measured coefficient in a tissue mimicking material phantom. The temperature rise estimated using the measured coefficient and that simulated based on a bioheat transfer equation showed a good agreement when the spatial averaged effect in the elevational direction was considered. The exponential decay time constants also agreed well within the range of measurement.
Theoretical study of the interfacial properties of carbon nanotube/epoxy resin nanocomposites
Authors: Serizawa Yurika , Yayama Tomoe , Akagi Fumiko
Published: March 2022

We demonstrate the effect of defects in carbon nanotubes (CNTs) on the interfacial interaction of CNT/epoxy nanocomposites by first-principles calculation. Atomistic interface models consisting of single-walled CNT and epoxy (diglycidyl ether of bisphenol A; DGEBA) were used. Total energy, the partial density of states, and electronic charge distributions were investigated. The results indicated a weak interaction between the defect-free CNT and the epoxy. When the DGEBA was placed over the site nearest to the defect on a CNT, it was found to be energetically stable. Moreover, shared charge density, which may result in a stronger interfacial interaction, was observed between the CNT and DGEBA. The presence of the defects is responsible for providing the valence electrons that do not participate in the carbon–carbon bond in the CNTs. Consequently, we conclude that the defects in the CNT are sometimes useful and may enhance interfacial adhesion at the interface of nanocomposites.

Lighting in sacred structures is an important part of architecture as it has physical and psychological impact on visitors and also influences how well a space is perceived. This research study intends to demonstrate that how expressions of light and daylight factor have a significant impact in the structure's design. The study utilizes a mixed method approach, with qualitative and quantitative analysis of lighting levels and visual integration of numerous sacred spaces, studied and compared through case studies. The findings aided in the development of guidelines for individual, collective and sacred lighting of landscapes in order to heighten the sense of sanctity inside the area. Since this study mainly focuses on natural illumination in the horizontal plane, more research can be conducted focused on the use of artificial lighting levels. The vertical plane, which incorporates walls and openings, can also be considered to see how it alters interior illumination.
Aspect-Aware Graph Attention Network for Heterogeneous Information Networks
Authors: Liu Qidong , Long Cheng , Zhang Jie , Xu Mingliang , Tao Dacheng
Published: March 2022

Graph Convolutional Networks (GCNs) derive in spiration from recent advances in computer vision, by stacking layers of first-order filters followed by a nonlinear activation function to learn graph representations. Although GCNs have been shown to boost the performance of many network analysis tasks, they still face tremendous challenges in learning from Heterogeneous Information Networks (HINs), where relations play a decisive role in knowledge reasoning. In addition, there may exist multi-aspect representations for every entity in HINs, and a fifilter learned with respect to one aspect is not guaranteed to behave similarly when applied to another aspect. We address these challenges by proposing the Aspect-Aware Graph Attention Network (AGAT), a model that extends GCNs with learnable weights to incorporate entity and relational information. Instead of learning the best representation for an entity, AGAT is able to learn contextual entity representations, which is more useful in downstream tasks. Experiments on link prediction and semi-supervised classifification verify the effectiveness of our algorithm.

A Dual-Flow Attentive Network with Feature Crossing for Chained Trip Purpose Inference
Authors: Lyu Suxing , Han Tianyang , Li Peiran , Luo Xingyu , Kusakabe Takahiko
Published: March 2022

Trip purpose is essential information supporting tasks in intelligent transportation systems, such as travel behaviour comprehension, location-based service, and urban planning. The observation of trip purpose is a necessary aspect of travel surveys. However, owing to the sampling volume, survey budget, and survey frequency, relying solely on travel surveys in the era of big data is a difficult task. There has long been a demand for an accurate, generalizable, and robust inference method for trip purposes. Although existing studies contributed significant efforts to improve the trip purpose inference, the potential of leveraging the trip chain is insufficient. The spatial correlations and chaining patterns hidden in travelled zones are worthy of further exploration. The unequal importance within trip chains has not been clearly represented. Additionally, complex activity-zone mutual interdependence has not been considered in previous models. Herein, we propose a framework- Dual-Flow Attentive Network with Feature Crossing (DACross), specifically for inferring the chained trip purpose. We form trip chains innovatively that treat trip activities and travelled geographic zones as two chains with mutual interactions. We propose DACross, which consists of two parallel attentive branches and a co-attentive feature crossing module, for fully learning the intra- and inter-chain dependencies. We conducted extensive experiments on four large-scale real-world datasets to evaluate not only the performance of DACross but also the generalizability of the proposed framework among different cities and scenarios. Notably, the Experimental results prove the overall superiority of the proposed DACross.

A comparison of three different electromagnetic scattering models for land surface delay-Doppler maps (DDMs) obtained from global navigation satellite system reflectometry (GNSS-R) along a Cyclone Global Navigation Satellite System (CYGNSS) track in the San Luis Valley, Colorado, USA, is presented. The three models are the analytical Kirchhoff solutions (AKS), the Soil And VEgetation Reflection Simulator (SAVERS), and the improved geometrical optics with topography (IGOT). Common inputs to the three models were defined by using field samples of soil moisture and texture, soil surface roughness measurements, and a digital elevation model (DEM). The resulting peak reflectivity profiles of the models and the CYGNSS data all had a dynamic range of 10 dB along the selected track, mainly due to the influence of topography. The reflectivities obtained from all three models agreed with one another to within 2.4 dB along the full length of the track. The models also showed general agreement with the corresponding CYGNSS data, although the modeled profiles were higher and smoother. Additional characterization of fine-scale surface roughness is identified as an area for future work to improve model fidelity. An intercomparison of DDM structure for three selected acquisitions is also provided.
Accurate and Simple Modeling of Eddy Current Braking Torque: Analysis and Experimental Validation
Authors: Mahfouz Abdullah
Published: March 2022

A simple and a straightforward mathematical modeling of the eddy current generated on a retarded rotating disk (RD) is proposed in this paper. First, the braking magnetic force, which curbs the movement of the disk is evaluated using the basic laws of electromagnetism. Second, the braking torque is related to the braking force through a polynomial function. Third, the equation of motion is derived considering the nonlinear behavior of the aerodynamic drag forces. The proposed model is validated experimentally for constant and alternating magnetic flux profiles with best fit rates (BFRs) more than 85% and 93% for both rotational velocity and braking torque, respectively. Programmable braking application is demonstrated using the proposed approach and its applicability is verified experimentally

To study current trends in the brucellosis epidemic process and perform molecular analysis of Brucella isolates from the territories of Southern and North Caucasian Federal Districts with long lasting unfavorable situation with brucellosis — the Republics of Dagestan (RD), Kalmykia (RK) and Stavropol Krai (SK).Materials and methods. The analysis of the brucellosis incidence in the North Caucasus Federal District and the Southern Federal District was carried out on the basis of data from the Rospotrebnadzor Departments for the period 2011–2020. Total 56 cultures of Brucella melitensis, isolated in 1999–2019 from patients with brucellosis that permanently resided in RD, RK and SK were studied.Results. The key factor contributing to the epidemic manifestations of brucellosis in the south of the European part of Russia is the persistence of epizootic foci in cattle and small ruminants. The leading concomitant factors are as follows: the presence in the region of "hidden" epizootic foci, uncontrolled production of food products of animal husbandry and its illegal sale to customers, unauthorized movement of animals and livestock products, untimely delivery (concealment) of sick cattle for stamping out. Results of molecular analysis of B. melitensis strains indicate the circulation of a mixed population of brucella, which is generally characteristic of the entire region, without a pronounced confinement of isolates to separate administrative territories. At the same time, the entire studied sample of strains can be divided into two groups (72% and 28% of strains) based on MLVA-16 genotypes by the variability in the Bruce 19 locus, which makes it possible to associate a part of the studied strains with the territory of their isolation.Discussion. The data obtained make it possible to scientifically substantiate the possibility of considering the affected territories of the Southern Federal District and the North Caucasian Federal District as a single common persistent active anthropurgic epizootic focus with circulation of a mixed, but typical for the region population of Brucella strains.

Introduction. For more than 10 years, the Tumen Region has been reporting steadily high rates of HIV infection prevalence. Among the groups at risk for HIV infection, a special place is occupied by the group of incarcerated individuals. This group is mostly represented by drug users, men who have sex with men, commercial sex workers. Diseases acquired during imprisonment or exacerbated in a prison setting become a problem not only for released inmates, but also for communities outside the prison system. Epidemiologically, it is critically important to identify the prison-related factors contributing to HIV progression, considering their unequal significance among incarcerated individuals and civilian population.The aim of the study is to identify and assess the risk factors affecting the HIV epidemic process in the high riskgroup density areas.Materials and methods. The study was performed using epidemiological study and stepwise logistic regression methods.Results. Since 2008, the epidemiological situation in prison settings has become increasingly severe, being characterized by higher rates of detection of HIV cases and HIV prevalence among inmates. The situation has also been aggravated by high death rates among HIV-infected inmates. Our study found that the high risk of fatal outcomes in HIV-infected inmates was associated with multiple parameters: the male gender, parenteral (injection drug use) HIV transmission, existing comorbidities – viral hepatitis and thoracic diseases.

The aim of the study was to analyze genetic characteristics of strains belonging to group A rotaviruses (RVA) circulating in Moscow in 2015–2020, including rare strains non-typeable by polymerase chain reaction (PCR).Materials and methods. A total of 289 stool samples were tested; the samples were collected from children aged 1 month to 17 years, hospitalized with acute gastroenteritis. Immunochromatography and real-time reverse transcription-polymerase chain reaction (real-time RT-PCR) assays were used for detection of rotaviruses in the samples. The rotavirus genome sequencing was performed using the Sanger technique and nanopore sequencing.Results and discussion. RVA RNA was detected in 131 clinical samples, and the G/[P] genotype was identified in 125 samples. The general profile showed prevalence of RVA strains with the G9P[8]I1 genotype (37%) followed by G3P[8]I2, G4P[8]I1, G2P[4]I2, G1P[8]I1, and G3P[8]I1 variants (18, 15, 11, 5, and 2%, respectively). Seven (5%) isolates were identified as GxP[8]. In 2015–2020, the region reported a decline in G4P[8]I1 genotype prevalence (from 39% to 9%) and an increase in the proportion of the G9P[8]I1 genotype (from 6% to 37%) as compared to 2009–2014. In 2018–2020, a large number of cases with the previously unknown DS-1-like reassortant strain with the G3P[8]I2 genotype were reported; the above strain has become widely common worldwide in the recent years. Nanopore sequencing was performed to analyze the genome of the G3P[8]I2 strain and the rare G4P[6]I1 strain. It was found that the G4P[6]I1 strain was phylogenetically related to porcine rotaviruses.Conclusion. In the recent years, the genetic diversity of RVA circulating in the Moscow Region has changed significantly. The obtained results prove the importance of continuous monitoring of rotavirus infection and selective sequencing of RVA genes to fine-tune data of the type-specific real-time RT-PCR. The ever-changing genetic composition of the circulating RVA strains calls for regular optimization of RVA genotyping systems based on real-time RT-PCR.

Introduction. The spread of the human immunodeficiency virus type 1 (HIV-1) has become a global concern and has approached the pandemic status. St. Petersburg, a major transportation, tourist, cultural, industrial center, and a border city, is characterized by high migration of the population. The growing number of migrants can contribute to importation and spread of new genetic variants of the virus and trigger recombination processes in the virus population in St. Petersburg and the Leningrad Region.The aim is to characterize the present-day HIV-1 subtype-specific profile and drug-resistance mutations among patients with virological failure on antiretroviral therapy (ART) in the Leningrad Region.Materials and methods. The study performed in 2016–2018 was based on clinical material from HIV-infected individuals living in the Leningrad Region and having confirmed virological failure on ART. The genetic diversity and distribution of drug-resistance mutations of the HIV-1 isolates were assessed through analysis of nucleotide sequences of the virus pol gene fragment that included regions encoding protease and the reverse transcriptase region.Results. In the group (n = 138), most of the patients had sub-subtype A6 (97.4%) common in Russia, though a few patients had subtype B and a recombinant containing circulating recombinant form CRF_03AB and sub-subtype A1. The tests showed that 95.79% of patients had at least one significant drug-resistance mutation; in most cases (73%) the virus was resistant to 2 classes of antiretroviral drugs and in some cases (8%) — to 3 classes. A total of 105 different drug-resistance mutations were found at 35 positions of the virus genome.Conclusions. The high prevalence of HIV-1 drug-resistance mutations among ART patients with virological failure calls attention to surveillance of drug resistance of the virus both among ART-experienced patients and ARTnaïve individuals.

Purulent-septic infections (PSI) of puerperas are one of the leading medical and social problems of modern health care. A significant prevalence, an upward trend, insufficient completeness of their identification and registration, along with a high degree of obstetric aggression — these are the modern features of this group of infections.To study the prevalence of PSI in the postpartum period (sepsis, peritonitis, endometritis, mastitis, and surgical site infections), identify risk factors, and assess the effectiveness of epidemiological surveillance of these infections, the analysis of publications on this topic has been carried out on several information resources: eLibrary, Google Scholar, PubMed, NCBI .Postpartum endometritis was found to be the most common form of PSI in puerperas, accounting for 3 to 20% PSI cases, and up to 40.0–54.3% among patients with postpartum inflammatory complications.Surgical intervention is one of the leading risk factors for the development of PSI after childbirth. For example, a cesarean section increases the risk of PSI by 5–20%.The systems of epidemiological surveillance for PSI of puerperas in different countries differ in the approach both to identifying, recording and registering cases, and to collecting information about the place and time of their highest risk.PSI of puerperas is a dynamically changing interdisciplinary problem at the intersection of obstetrics, gynecology and epidemiology. Despite the data on the prevalence of certain nosologies and their risk factors, there are a number of issues that can be discussed and need to be addressed.
