A Review Paper on Reuse of Plastic Waste as Pavement Construction Material
Authors: Gupta Anjali , Chandrakar Vishal
Published: March 2023

Abstract: The exponential rise in the production of plastic and the consequential surge in plastic waste have led the scientists and researchers look out for innovative and sustainable means to reuse/recycle the plastic waste in order to reduce its negative impact on environment. Construction material, converting waste plastic into fuel, household goods, fabric and clothing are some of the sectors where waste plastic is emerging as a viable option. Out of these, construction material modified with plastic waste has garnered lot of attention. Modification of construction material with plastic waste serves a dual purpose. It reduces the amount of plastic waste going to landfills or litter and secondly lessens the use of mined construction materials, thereby mitigating the negative impact of construction industry on environment. This article summarizes advances related to the use of plastic waste as a component of building materials. The inclusion of plastic waste as a binder, aggregate, fine aggregate, modifier or substitute for cement and sand in the production of bricks, tiles, concrete and roads has been comprehensively considered. The effect of the addition of plastic waste on strength properties, water absorption, durability, etc. was also discussed in detail. Studies reviewed for this review were categorized according to whether they used plastic waste to produce bricks and tiles or concrete for road construction.

Published: March 2023

The learning process must actively involve students and provide opportunities for them to study and prove the theories they learn. This study determined the influence of the application of Project-Besad Learning (PjBL) using a laboratory approach on learning outcomes and critical thinking in marine biology. This study used a descriptive quantitative method, with the independent variable being the implementation of PjBL with a laboratory approach and involved 32 students in the sixth semester of Biology Education at Pattimura University Indonesia enrolled in marine biology courses. The dependent variables were students' learning outcomes and critical thinking, and the data were collected by tests (knowledge and critical thinking) and observations (attitude and skill). The analysis revealed that the integration of the PjBL with a laboratory approach had a weak effect on knowledge (0.003 <p 0.005), a moderate effect on attitude and skill (0.000 <p 0.005), and a strong effect on critical thinking. The regression analysis showed that there was a correlation between the independent variable and student knowledge (R2 = 0.257 or 25%), attitude (R2 = 0.471 or 47.1%), psychomotor/skill (R2 = 0.470 or 47%), and critical thinking (R2 = 0.934 or 93.4%). In conclusion, the implementation of PjBL using a laboratory approach can improve student learning outcomes and critical thinking in marine biology.
Middle school students' errors and its relationship on the concept of number line, number system, and the properties of real numbers
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Hye Young , Kwon Oh Nam
Published: March 2023

Objectives This study explores middle school students' errors in explaining the concept of the number line, number system, and completeness among the properties of real numbers. Furthermore, it aims to explore the relationship between each error.
Methods To conduct this study, 12 middle school students were recruited and interviewed. The students' responses were analyzed and compared with textbooks and tutorials. Through this analysis, the connection between errors in the number line and number system, and the meaning and relationship of the properties of real numbers was examined.
Results As a result, errors in number representation and number systems were found to be linked to improper use of definitions or theorems in explaining completeness. Additionally, errors in the method of mapping irrational numbers on the number line, and the belief that it is impossible to map irrational numbers on the number line were linked to logically improper reasoning in explaining completeness.
Conclusions To address these errors, the study suggests three implications for the direction of textbook narrative and teachers' pedagogical methods. First, it is necessary to present a link that shows that the number line can be enlarged. Second, the distinction between fractions, decimals, and number systems should be emphasized. Third, it is necessary to present various endpoints in the section on the number line, and a method to freely change the perspective of potential and actual infinity. Based on these results, the study derives implications for the direction of textbook narrative and teachers' pedagogical methods.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Eunha
Published: March 2023

Objectives The purpose of this study were presenting the direction of research by identifying the overall research trend and research topic of papers related to reading comprehension for the deaf and hard-of-hearing in Korea.
Methods As a result of selection based on the paper selection criteria in the domestic database, 28 papers were finally selected. The thesis was cross-analyzed according to the research subject, research period, research type, and research topic, and the research content was subdivided and organized.
Results As a result of the analysis, in the overall trend, the number of studies after 2012 decreased significantly compared to studies from 2001 to 2011. Intervention studies were the most common research methods, and research topics could be divided into factors related to reading comprehension, reading instruction, and reading activities. In research content, factors related to reading comprehension can be divided into personal factors and external factors, and reading instruction can be divided into understanding check-based instruction, vocabulary-based instruction, visual cognitive strategies based instruction, and reading instruction according to the pedagogical model. In reading activities, it was found that activities using visual materials were mainly performed.
Conclusions As for the direction of research on reading comprehension for the deaf and hard-of-hearing in Korea, it is judged that it is necessary to expand the characteristics of cognitive strategies and the method of teaching strategies by considering the personal and external factors of the deaf and hard-of-hearing.
The Mediation Effect of Academic Performance and Career Preparation Behavior in the Relationship between Metacognition and Calling in University Students
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Do-Hee , Lee Hyun-Ju
Published: March 2023

Objectives This study aims to observe the relationship between metacognition and the calling of university students to investigate whether academic performance and career preparation behavior mediate that relationship.
Methods Online questionnaires were collected from 239 university students (18-28 years old), and the SPSS and PROCESS Macro programs were used to conduct correlation analysis, hierarchical regression analysis, and mediation model analysis.
Results Metacognition was found to have a significant positive correlation with academic performance, career preparation behavior, and calling. In addition, although the direct effect of metacognition on calling was not found to be significant, it had a positive effect on calling when it was mediated through career preparation behavior. On the other hand, the effect of metacognition on calling through academic performance, and the effect on calling of progressing sequentially through academic performance and career preparation behavior, were not found to be significant. In addition, among the sub-factors of career preparation behavior, self-understanding behavior, and career competency improvement behavior completely mediated the relationship between metacognition and calling, while the mediation effect of career world exploration behavior was not significant. In summary, it shows that the more effectively metacognition is utilized, the greater one’s understanding of oneself, and the more one will participate in activities that prepare one for employment (e.g., club activities, mock practice, career-related volunteer activities, or fieldwork experience). Such career development has a positive effect on calling.
Conclusions The results of this study indicate that metacognition is an important cognitive competency that contributes not only to academic performance but also to career development and calling formation. Therefore, interventions that encourage people to explore values and meaning, efficiently plan their career paths, and promote actions using metacognition can help people live a life of self-fulfillment through their career.

Сонгууль, сонгуулийн үйл явц тэр дундаа сонгуульд нэр дэвшигчийн имижийг бүрдүүлэх явдал нь төлөөллийн ардчилалын нэгэн бүрэлдэхүүн үнэт зүйл юм. Төлөөллийн ардчилалын өөр нэгэн үнэт зүйл бол иргэдийн нийгэм улс төрийн оролцооны асуудал юм. Өөрөөр хэлбэл төлөөллийн ардчилалын зарчмын дагуу иргэд өөрийн сонгосон гишүүнээрээ дамжуулж төрийг удирдах үйл хэрэгт оролцох явдал юм. Энэ талаар эрдэмтэн Gustave A De Cocq “Иргэдийн оролцоо бол ардчиллын оршин тогтнох, сүүлийн тулах цэг”1 хэмээн бичсэн байдаг. Манай улсын хувьд 1992 оноос эхлэн төлөөллийн ардчиллын зарчмын дагуу Улсын Их Хурал, Ерөнхийлөгч, Иргэдийн Төлөөлөгчдийн Хурлын сонгуулийг удаа дараа явуулж иргэдийн үндсэн хуулиар олгогдсон улс төрийн оролцооны хэлбэрийг хангаж ирлээ. Иргэд сонгуульд оролцон саналаа өгөх нь улс төрийн оролцооны нэгэн чухал хэлбэр байдаг хэдий ч өнөөдөр зөвхөн иргэд санал өгөгч, сонгогч байхаас татгалзаж эхэлж байгаа нь тэдний сонгуульд оролцох идэвхээс ихээхэн шалтгаалж байдаг. Иргэдийн улс төрийн оролцоо зөвхөн сонгуулиар хязгаарлагдахгүй нь ойлгомжтой бөгөөд бид оролцооны олон төрлүүдийг ашиглаж сурах нь чухал юм. Мөн сонгуулийн кампанийн үйл явцад нэр дэвшигчийн имиж бүрдүүлэлтийн талаарх асуудлыг судлан дүгнэх хэрэгтэй. Учир нь зарим талаараа иргэд, сонгогчдод тухайн нэр дэвшигчийн имиж таалагдахгүй хүлээн зөвшөөрөхгүйгээс байгаагаас шалтгаалан тэдний улс төрийн оролцоо буурах хандлагатай байж болох юм. Иймд энэхүү өгүүлэлээ сонгуулийн албан ёсны сурталчилгааны үед нэр дэвшигчийн улс төрийн имижийг “шинэ бодлогын” зарчмын дагуу хэрэн бий болгох талаар онол, практикийн зарим асуудлыг хөндөн авч үзэхийг зорив

Authors: Rattes Plínio , Barros José Marcio
Published: March 2023

O presente texto traz uma análise da gestão compartilhada e colaborativa que ocorre no âmbito das três Praças CEU localizadas na cidade de Feira de Santana, na Bahia, a partir de duas chaves conceituais – diversidade e participação social. O programa Praça CEU – Centro de Artes e Esportes Unificados – é uma iniciativa do governo federal, executada em parceria com prefeituras municipais, que abrigam ações voltadas à promoção da cultura, do esporte, do lazer, da assistência social e da qualificação e aperfeiçoamento laboral. O programa foi idealizado para ser gerido, no âmbito governamental, de forma intersetorial e, no âmbito local, de forma compartilhada com a sociedade civil, a partir de um grupo gestor tripartite composto por moradores, entidades e poder público local, com poder deliberativo. Dessa forma, apresentamos nesse trabalho uma análise sobre a efetividade e a aplicabilidade do modelo de gestão proposto e, sobretudo, verificamos em que medida os discursos de participação social e diversidade cultural se materializam ou não nas Praças pesquisadas.
Regularidades discursivas dos casos de feminicídio no Diário do Sertão
Authors: Lacerda Luana , Melo Ricardo , Rabay Glória
Published: March 2023

Este artigo busca compreender como é feita a cobertura jornalística dos casos de feminicídio no Sertão Paraibano, a partir do discurso utilizado pelo veículo Diário do Sertão, um dos mais importantes da região, em relação aos crimes extremos de gênero/patriarcado. Foram analisados todos os sete casos de feminicídios ocorridos no Sertão da Paraíba no ano de 2020 e analisadas as posições discursivo-ideológicas presentes nas matérias. O que se observa é a despolitização do crime, pois nem sempre os assassinatos são retratados como feminicídios, bem como a descontextualização do cenário de violência contra as mulheres. As autoridades policiais são a principal e, na maioria das vezes, a única fonte ouvida. Além disso, há o silenciamento de informações importantes sobre prevenção e disques denúncias.

RESUMEN. Introducción: La regeneración natural es una solución de bajo costo y basada en la naturaleza para restaurar parte de los hábitats degradados por la deforestación. Objetivo: Documentar la composición florística de un fragmento de vegetación en regeneración de bosque muy húmedo premontano. Métodos: Hicimos un inventario florístico en 5,59ha mediante recorridos exhaustivos. Resultados: Identificamos 74 familias, 144 géneros y 170 especies nativas, y 15 familias, 21 géneros y 22 especies introducidas, y un híbrido. Las familias con mayor riqueza de géneros y especies fueron Asteraceae, Fabaceae, Solanaceae, Rubiaceae, Euphorbiaceae, Polypodiaceae, Lauraceae y Pteridaceae. Los géneros con mayor riqueza de especies fueron Solanum, Pleopeltis, Pteris, Croton y Piper. Hallamos dos especies endémicas, Costus montanus y Sechium tacaco. El 95% de las especies son terrestres, 4% epífitas facultativas y 1% holoepífitas; 30% árboles, 29% arbustos, 27% hierbas, 9% lianas y 5% sufrútices. Cerca del 64% son estrictamente heliófitas, y un 36% de las especies pueden tolerar la sombra. 148 especies tiene al menos nombre común. Conclusión: Este bosque se encuentra en un estado temprano de regeneración, con una composición de especies típica de los bosques premontanos del Valle Central costarricense, por lo que es relevante conservarlo.
Rib fracture as a cause of hindlimb lameness in a horse
Authors: Rihuete Pablo Jimenez , Staempfli Simon , Watterhouse Mathew , Martinez Luis M. Rubio
Published: March 2023

A 2-year-old racing Thoroughbred gelding in training was presented with
moderate (6/10) right hindlimb lameness unresponsive to regional
anaesthesia of the right hind limb. Gamma scintigraphic examination
revealed severe, focal, increased radio-pharmaceutical uptake over the
dorsal aspect of the right 18th rib, which had an abnormal contour.
Ultrasonographic examination of this area confirmed the presence of a
complete, displaced fracture of the proximal aspect of the right 18th
rib. Local infiltration with local anaesthetic around the 18th right rib
(10ml cranial and 10ml caudal to the fracture site) abolished the right
hindlimb lameness. A diagnosis of rib fracture causing moderate
ipsilateral hindlimb lameness was made. The horse returned to walking
exercise after 12 weeks of rest and was reported to be sound on the same
limb 12 months after presentation. Caudal rib fractures should be
considered as possible cause of hind limb lameness. Local diagnostic
anaesthesia around the fracture site can aid localise the origin of
lameness.
Afghanistan in the Trap of an Ethnic Security Dilemma: Is There Any Solution on the Horizon?
Authors: Hussaini Sayed Reza
Published: March 2023

Afghanistan represents one of the most complex mosaics of ethnic groups
in the world and its contemporary history has been characterised by
ethnic hierarchy. Pashtuns domination of the country and their
discriminatory policies toward non-Pashtuns have had long-term effects
in destroying inter-ethnic trust. The hierarchical relationships among
ethnic groups have always been an obstacle to creating ethnic harmony
even in pre-war Afghanistan. The paper, by adopting ‘ethnic security
dilemma theory,’ attempts to analyse how and why ethnicity in
Afghanistan was politicised and morphed into fault line that finally
surfaced in the form of civil war in 1990s. It will discuss the impacts
of internecine war on inter-ethnic relations and explores the possible
options to deal with the long-standing ethnic security dilemma. Being
caught in an ethnic trap, the paper argues, only a meaningful
power-sharing mechanism can glue the future Afghanistan together.

deposition, tau tangles, neuroinflammation and neurodegeneration. Some
of the pathological changes could be shown in vivo by positron emission
tomography (PET) and magnetic resonance imaging (MRI) biomarkers which
play a key role in diagnosing AD. Fluorodeoxyglucose positron emission
tomography (FDG-PET) can reflect and predict dysfunction. Aβ-PET was
sensitive for the diagnosis of early AD but cannot distinguish the
severity of AD. Tau-PET can compensate for the deficiency of Aβ-PET. Tau
tangles were positively correlated with the severity of AD, and also
associated with cognitive impairment. Probes targeting neuroinflammation
of AD have been developed, but further study is needed to validate its
effectiveness. Conventional MRI performs high tissue contrast that can
show structural changes and has been routinely applied in clinical
practice, such as evaluation of cerebral atrophy. Advanced MRI sequences
(such as DTI、ASL、MRS、BOLD and QSM) that can provide additional
information beyond structure that includes brain microstructure, blood
perfusion, metabolite concentration, brain activity, connections and
networks between brain regions, iron deposition, etc. The integrated PET
and MR may improve the diagnostic efficiency of AD.

Rabies, a fatal zoonotic viral encephalitis kills tens of thousands of
people each year in India, representing one third of the estimated
global rabies burden. A detailed understanding of the molecular
epidemiology of the Rabies lyssavirus (RABV) in India is limited due to
the low availability of sequences from the country. In this study we
examined the feasibility of direct sequencing of clinical samples
(archived human and canine brain tissues, 10 each), for detection and
recovery of whole genome sequences of RABV, on the MinION – single
molecule nanopore sequencing device. Using an amplicon-based approach,
complete RABV genomes were recovered from all the 20 samples, archived
from 2003 to 2019, from 4 southern states of India. Phylogenetic
analysis revealed that all 20 sequences from this study belonged to the
Arctic-like (AL) 1a lineage. Divergence estimation of sequences revealed
that all the circulating RABV strains within India are diverged in last
60 years from the previous ancestor. The genetic relatedness and close
clustering of the sequences in the study suggests the continued
propagation of AL1a in the region, across state boundaries. Genomic
surveillance can provide unique insights into rabies spread and
persistence that can direct control efforts in India.

Authors: W Gary Chien , Cesar Trevor , Goharderakshan Nathan , Li Qiaowu (Zoe) , Tovar Stephanie
Published: March 2023

Objective: To evaluate patient and healthcare system factors in
telemedicine utilization in a large, diverse population. Data Sources
and Study Setting: Retrospective study of patient visits across Kaiser
Permanente Southern California between January 1, 2019, and June 30,
2021. Study Design: Patient factors included age, gender, ethnicity,
median household income, primary spoken/written language, marital
status, and registration on kp.org. Healthcare factors included type of
visit, provider age, gender, specialty, number of years in practice and
primary language. Data Collection/Extraction Methods: Rates of
utilization compared between office and virtual visits, prior to and
after March 2020, with an interrupted time series and slope analysis.
Principal Findings: There were 177,171,288 visits during the study
period. There was a decrease in patient visits after March 2020
(lockdown), driven by a sharp decline in office visits. Within three
months of lockdown, total visits increased until the end of study, at
2.8 million/month, compared to 2.5 million/month prior to lockdown,
driven by office visits that approached pre-lockdown and high
telemedicine visits. In a multivariate regression analysis, there were
no significant differences in patient age, race, gender, income, marital
status, language, and kp.org registration in telemedicine utilization.
Providers with 6-10 years in practice, aged < 30 utilized the
most telemedicine (p=.01). General surgery, medical specialties, OBGYN,
pediatrics and psychiatry utilized more telemedicine compared to primary
care, but podiatry and surgical specialties utilized less (p <
0.01). Conclusions: In a large, diverse patient population, no
significant healthcare disparities were found in telemedicine
utilization, contrary to what most current literature shows. Results of
this study may prompt more investigation to the role of telemedicine in
various populations.
Research on the Effects of the Global Static Management Policy against COVID-19 in 2022 on Clinical Trials in Shanghai
Authors: Tan Zhaodan , Xu Zengguang , Shi Yan
Published: March 2023

Aims: To improve the countermeasures of clinical trial institutions
against major public health events such as COVID-19. Methods: A
questionnaire was created to investigate the effects of the global
static management policy against COVID-19 on clinical trials in Shanghai
in 2022. And the convenience sampling combined with snowball sampling
were adopted to interview clinical research coordinators (CRC) and
clinical research associates(CRA) on the platform of SOJUMP as well as
WeChat. Results: 156 valid questionnaires were collected, with an
effective recovery rate of 93.98%. 98.07% of the respondents believed
that the effects was severe. The extent of effects on different links of
clinical trials was different (rank sum test P<0.01), being
great on medication/follow-up (76.28% of significant effects),
monitoring/audit (74.36%) and screening/admission (71.79%).The
protocol deviations associated with out of visit window (experienced by
94.23% of respondents, during the static management policy), inspection
(78.85%), medication (67.95%) and withdrawal (62.82%). And the
interviewees reported 49.66% of the exclusion should blame the epidemic
situation. The development of online-office or remote-ethics meetings
alleviated the impact of lockdown policy on approval/ethics/contract and
data cleaning/site closing. 90.98% of oral drugs could be sent by
express delivery, but only 1.28% had the experience of online informed
consent and remote inspection. Conclusions: We shall speed up the
application of the intelligent clinical trial system and remote
monitoring system, realize the transformation to a new model of
patient-centered clinical trial, and improve the ability to cope with
major public health events such as COVID-19.
Continuity of global MODIS terrestrial primary productivity estimates in the VIIRS era using model-data fusion
Authors: Endsley K. Arthur , Zhao Maosheng , Kimball John , Devadiga Sadashiva
Published: March 2023

The NASA Terra and Aqua satellites have been successfully operating for
over two decades, exceeding their original 5-year design life. However,
the era of NASA’s Earth Observing System (EOS) may be coming to a close
as early as 2023. Similarities between the Moderate Resolution Imaging
Spectroradiometer (MODIS), aboard Aqua and Terra, and the Visible
Infrared Imaging Radiometer Suite (VIIRS) sensors aboard the Suomi NPP,
NOAA-20 and NOAA-21 satellites enable potential continuity of long-term
earth observational records in the VIIRS era. We conducted a
comprehensive calibration and validation of the MODIS MOD17 product,
which provided the first global, continuous, weekly estimates of
ecosystem gross primary productivity (GPP) and annual estimates of net
primary productivity (NPP). Using Bayesian model-data fusion, we
combined an 18-year record of tower fluxes with prior data on plant
traits and hundreds of field measurements of NPP to benchmark MOD17 and
to develop the first terrestrial productivity estimates from VIIRS. The
updated mean global GPP (NPP) flux from MOD17 and the new VNP17 for
2012-2018 is 127 ±2.8 Pg C year-1 (58 ±1.1 Pg C year-1), which compares
well with independent top-down and bottom-up estimates. Both MOD17 and
VNP17 depict upward productivity trends over recent decades, with
2000-2018 MOD17 GPP (NPP) rising by 0.47 (0.25) Pg C year-2 but slowing
to 0.35-0.44 (0.11-0.13) Pg C year-2 over 2012-2021, with a greater
reduction in the NPP growth rate. The new VIIRS VNP17 product has the
potential to extend these continuous estimates of global, terrestrial
primary productivity beyond 2030.
Hypersensitivity of Southern Ocean air-sea carbon fluxes to background turbulent diapycnal mixing
Authors: Ellison Elizabeth Catherine , Mashayek Ali , Mazloff Matthew R.
Published: March 2023

The Southern Ocean (SO) is the worlds largest high nutrient low
chlorophyll region and has a plentiful supply of underutilised
macronutrients due to light and iron limitation. These macronutrients
supply the rest of the neighboring ocean basins, and are hugely
important for global productivity and ocean carbon sequestration.
Vertical mixing rates in the SO are known to vary by an order of
magnitude temporally and spatially, however there is great uncertainty
in the parameterization of this mixing, including in the specification
of a background mixing value in coarse resolutation Earth System Models.
Using a biogeochemical-ocean model we show that SO biomass is highly
sensitive to altering the background diapycnal mixing over short
timescales. Increasing mixing enhances biomass by altering key
biogeochemical and physical parameters. An increased surface supply of
iron is responsible for biomass increases in most areas, demonstrating
the importance of year round diapycnal fluxes of iron to SO surface
waters. These changes to SO biomass could potentially alter atmospheric
CO2 concentration over longer timescales, demonstrating the importance
of accurate representation of diapycnal mixing in climate models.
Moment Tensor Estimation of Event S1222a and Implications for Tectonics Near the Dichotomy Boundary in Southern Elysium Planitia, Mars

On May 4th, 2022 the InSight seismometer SEIS recorded the largest
marsquake ever observed, S1222a, with an initial magnitude estimate of
Mw 4.7. Understanding the depth and source properties of this event has
important implications for the nature of tectonic activity on Mars.
Located ~37 degrees to the southeast of InSight, S1222a
is one of the few non-impact marsquakes that exhibits prominent ratio
surface waves. We use waveform modeling of body waves (P and S) and
surface waves (Rayleigh and Love) to constrain the moment tensor and
quantify the associated uncertainty. We find that S1222a likely resulted
from dip-slip faulting in the mid-crust (source depth
~18 – 28 km) and estimate a scalar moment of 3.51015 –
5.01015 Nm (magnitude Mw 4.3 – 4.4). The best-fitting focal mechanism
is sensitive to the choice of phase windows and misfit weights, as well
as the structural model of Mars used to calculate Green’s functions. We
find that an E-W to SE-NW striking thrust fault can explain the data
well, although depending on the choice of misfit weighting, a normal
fault solution is also permissible. The orientation of the best-fitting
fault plane solutions suggests that S1222a takes place on a fault system
near the martian crustal dichotomy accommodating relative motion between
the northern lowlands and southern highlands. Independent constraints on
the event depth and improved models of the (an)isotropic velocity
structure of the martian crust and mantle could help resolve the
ambiguity inherent to single-station moment tensor inversions of S1222a
and other marsquakes.
Large-scale image classification with multi-perspective deep transfer learning
Authors: Wu Bin , Zhang Tao , Mao Li
Published: March 2023

Most research efforts on image classification so far have been focused on medium-scale datasets. In addition, there exist other problems, such as difficulty in feature extraction and small sample size. In order to address above difficulties, this paper proposes a multi-perspective convolutional neural network model, which contains channel attention module and spatial attention module. The proposed modules derive attention graphs from channel dimension and spatial dimension respectively, then the input features are selectively learned according to the importance of the features. We explain how the gain in storage can be traded against a loss in accuracy and/or an increase in CPU cost. In addition, we give the interpretability of the model at multiple scales. Quantitative and qualitative experimental results demonstrate that the accuracy of our proposed model can be improved by up to 3.8% and outperforms the state-of-the-art methods.

Published: March 2023

One of the basic assignments of modern society is preserving the quality of freshwater resources, especially drinking water. Line facilities potentially pose a higher risk to the environment due to the large length of the extension and the diversity of the environment they may affect. Storm water drained from railway could pollute the surrounding land besides railway track. Based on the data from available research, it has been determined that heavy metals (iron, copper, zinc, manganese and chromium), polycyclic aromatic hydrocarbons (PAHs) and herbicides stand out in significant quantities from substances hazardous to the environment. This paper proposes the solutions using some self-sustainable techniques, based on the analysis railway drainage needs. The proposals that have been made refer to the open-air railway and railway station.
Thermal-hydraulic-mechanical coupling mechanical behavior and acoustic emission characteristics of deep sandstone

Published: March 2023

Based on the deep in situ mining environments with ?three high?, a triaxial
compression experiment of water-saturated sandstone under the conditions of
150?C, 110 MPa confining stress and 105 MPa pore water stress was carried
out. The results show that the creep deformation stage produces a surge in
acoustic emission energy when the radial deformation of sandstone changes
from expansion to rapid compression, and the sandstone is sheared by a
single crack when it is damaged. From deformation monitoring and acoustic
emission energy analysis, the thermal-hydraulic-mechanical (THM) coupling
environment will cause irreversible changes to the internal stress
distribution, pore structure and mineral framework of sandstone. In the THM
coupling experiment, the irreversible impact of the rock sample due to the
long-term simulation of the "three high" environment and the difference
caused by the impact on the final experimental results should be considered.

Published: March 2023

Geothermal energy has become one of the new energy sources of great concern
due to its wide distribution, abundant reserves and green, clean and
renewable advantages. In view of the advantages of both geothermal energy
development potential and abundant seawater reserves in the coastal areas,
granite is taken as the research object, and the surface topography under
different temperatures (100?C, 200?C, 300?C, 400?C, and 500?C) and
different thermal shock cycles (0, 5, 10, 15 and 20) is obtained. Based on
3-D scanning technology, the damage details of the surface are
reconstructed, and the roughness parameters of the surface are obtained. The
maximum height, the maximum valley depth and the arithmetic mean height
increase with the increase of the temperature and the number of times, but
the maximum peak height does not change significantly. Based on fractal
theory, the variation law of the fractal dimension is further discussed. The
impact regions that affect the fractal dimension and thermal damage are
divided: the weak impact region, the transition region, and the significant
impact region. It lays a corresponding basic law for the heat exchange
efficiency and strength characteristics of dry hot rock.

The rapid development of technology affects people’s lives, including education, and virtual reality is one of many digital learning media that can be useful for learning. Virtual reality allows users to interact with the environment through a virtual world. With this concept in mind, an application to support gamelan learning based on Virtual Reality was developed called Peking Metagamelan Virtual Reality. Peking is a gamelan instrument made of bronze with rectangular blades. This application needs to know the user’s opinion regarding its performance and usability in its development. Therefore, the Think-aloud method assisted in the usability analysis process in the VR Metagamelan Peking application. The Think-aloud approach helps to express what the user feels and thinks when using the application. The research process involved five respondents from various educational backgrounds and different experiences. Respondents were asked to work on several task scenarios that were ordered. During the task scenario, respondents were asked to convey their thoughts regarding the application they were trying. The results were then analyzed and produced some recommendations for further improvements to the VR Metagamelan Peking application. The recommendations included improving the application interface, adding several features, and reducing the character’s speed.
