Authors: Almoshantaf Mohammad Badr , Swed Sarya , Alibrahim Hidar , Bohsas Haidara , Nasif Mohmad Nour , Hafez Wael
Published: March 2023

Background:  The worldwide burden of cancer continues to rise, mainly due to global demographic changes and an increase in cancer-causing habits, such as smoking, epically in low-income countries. The Syrian National Cancer Registry (SNCR)estimates that 17,599 new cancer cases were diagnosed before the start of the war in 2011. According to statistics from the Al Bairouni 2020 hospital-based registry, which includes data on more than 60% of Syrian cancer patients, the number of cancer diagnoses has been rising in Syria. There is no research conducted in Syria to determine people’s knowledge about cancer and risk factors, symptoms, and signs. This research aims to determine how well-informed Syrians were on the following topics:(i) the age-related risk and prevalence of cancer; (ii) cancer signs and symptoms; and (iii) cancer risk factors. In addition, determining how well-informed different demographic categories.
 
Method: This is a cross-sectional study which was conducted in Syria. Participants who were eligible to participate in the study who were residents of Syria irrespective their age or gender. The instrument of survey was a structured questionnaire the content of which was adapted from the validated cancer awareness measure (CAM) the cam was translated to Arabic and a scoring system was applied to the questionnaire. The questionnaire was distributed via several social media platforms.
 
Results: A total of 1463 participants completed the questionnaire. There were 768 respondents (52.5%) said that there is no relation between age and cancer. Almost all the participants (85.6%) thought that the breast cancer is the most common cancer among women, while around half of the participants (55.1%) reported that the prostate cancer was the most common cancer among males. The most frequently reported cancer symptom was unexplained weight loss (73.2%), followed by unexplained swelling/lump (66.5%). The level of knowledge about cancer signs/symptoms among the participants were good in 623 (42.6%), fair in 594 (40.6%), and poor in 246 (16.8%). The most commonly recognized risks of cancer were smoking (83.5%).
 
Conclusion: According to this research, taking into consideration the war and the bad economic situation that Syria is facing, Syrians’ knowledge towards cancer is acceptable. However, it is not meeting the ideal expectations. More research should be held to dig deeper into this issue.
Prenatal Diagnosis of a Fetus with Partial Duplication and Deletion of Chromosome 18 Due to Maternal Pericentric Inversion 18
Authors: Vásquez Salguero Manuel Alejandro , Saldarriaga Gil Wilmar
Published: March 2023

The phenotype of structural chromosome 18 mutations is highly heterogenous, clinical manifestations may range from mild to severe, they have been widely studied in the literature, however, there are few cases where two or more mutations are present in the same individual, reports where these alterations are caused by a maternal pericentric inversion and diagnosed prenatally are even rarer. Affected individuals are generally characterized by low birth weight, intellectual disability, heart defects, musculoskeletal abnormalities, craniofacial anomalies, among others. We describe the case of a masculine fetus from a non-consanguineous marriage obtained at week 29 of gestation. 27-year-old mother, G2C1, she started antenatal care at week 11 of pregnancy in the Hospital Universitario del Valle, in Cali, Colombia. Ultrasound at the 11th week of gestation showed a 3.9 mm nuchal translucency (>95p), subsequently at week 18th a new ultrasound found a 6mm nuchal translucency (>95p); suspecting a chromosomal aberration an amniocentesis was carried out at week 18th, a 756-band resolution karyotype reported: 18 partial trisomy (from 18p.11.2 to the centromere and from 18q11.22 to 18qter), and chromosome 18 partial monosomy (from 18pter to 18p11.2 and from the centromere to 18q11.2). The parents also underwent genetic testing, the karyotype of the mother exhibited a pericentric inversion of the 18 chromosome (46,XX,inv(18)(p11.2q11.2), no abnormalities were found in the father’s genetic material. At week 24 of gestation detailed anatomy ultrasound showed left diaphragmatic hernia, multicystic dysplastic kidney, and polyhydramnios. After explaining the diagnosis and providing genetic counseling, the patient requested voluntary interruption of pregnancy as established by the c-355/06 law of the Colombian constitutional court. A 1,180 g fetus as obtained. The structural rearrangement of this case may be explained by an error in maternal meiosis, oogenesis. During meiosis 2 an anomalous disjunction in the chromosome 18 took place, where the two short arms were separated from the long arms, the latter isochromosome was the one that the fetus received, thus, leading to the described mutation. The aim of this case report is to provide to the scientific literature the first case of prenatal diagnosis of a fetus with partial trisomy and partial monosomy of specific bands of the chromosome 1, due to maternal pericentric inversion, while also highlighting the value of early prenatal diagnosis, in order to make choices regarding voluntary interruption of pregnancy, pregnancy follow up, or planning the delivery method, allowing adequate genetic and reproductive counseling for future pregnancies.

Published: March 2023

This practice report highlights changes made to a first-year unit in an Urban and Regional Planning degree, designed to enhance students’ levels of cultural competency. We briefly discuss the history of cultural competency highlighting a lack of application in the field of urban planning. We report on a practical case study where six strategies were developed to enhance students’ cultural competency. We reflect on the experience of designing and delivering a unit called Diversity and Cultural Planning. The results from 38 students who completed a cultural competency survey at the start and at the end of term, revealed an increase in overall self-assessment scores of around 12%. As cities become more diverse, this practical case study highlights the need and benefits of enhancing the cultural competency of those who both teach and learn about urban planning.

Published: March 2023

Issue 1 of Volume 14 is published at an exciting and challenging time for education.  The availability of generative artificial intelligence (AI) tools is causing disruption across sectors.  Responses range from complete bans in some compulsory education and tertiary institutions, to putting in place creative ways to deploy these new technologies as productive learning and work tools.  The concerns about the risks to integrity of assessment and reputational risks to institutions and sectors are valid and also require close attention.  In a short time, a lot of advice has been offered and forums discussing approaches to integrating generative AI into work as well as assessment practices abound.   The Student Success team has been watching these developments with great interest. We believe these tools have utility for both learning practice and helping build students’ capacity to succeed.  We look forward to receiving evidence-based submissions on this important topic for future issues.  In this general issue we present a broad spectrum of articles and practice reports on student engagement, this time with authors from Australia, South Africa, Canada and the US.

Authors: Gonçalves Ângelo Ricardo Kruger , Silva André Luiz Ferreira , Fontoura Luís Henrique Salla , Lopes Gustavo Rodrigues , Vasconcelos Ana Lorena Souza de , Borges Yan Ohana Oliveira Costa
Published: March 2023

A principal limitação deste estudo foi o fato de que o SUS não SUS não possui ainda um registro abastecido com os dados epidemiológicos sobre a cirurgia bariátrica na região Norte e da natureza clínica dos pacientes submetidos à cirurgia bariátrica tanto regional quando em cenário nacional. Outro fator é que a Autorização de Internação Hospitalar (AIH) disponibiliza apenas sexo e idade e neste estudo não foi possível verificar essas variáveis. Além disso, informações acerca do IMC e comorbidades prévias são fundamentais para identificar os perfis dos pacientes operados e entender dados relacionados ao acesso, mortalidade, tempo de internação, entre outras variáveis, objetivou-se assim traçar o perfil epidemiológico dos pacientes submetidos à cirurgia bariátrica na região Norte e comparar com outras regiões do Brasil As publicações sobre cirurgia bariátrica são inúmeras na literatura internacional. Entretanto, nosso estudo verificou que existem poucos trabalhos nacionais sobre o assunto, e destes raros envolvem a descrição correta por região. Além disso, há uma falta importante no abastecimento das bases de dados com informações sobre esse procedimento principalmente na região Norte quando comparado às demais regiões brasileiras. Há necessidade também de uma articulação com os demais serviços presentes na rede de atenção à saúde, objetivando instituir uma linha de cuidado mais efetiva e que abarque, não apenas a cirurgia bariátrica, mas também que seja possível um acompanhamento em saúde dos indivíduos com obesidade em cada região do Brasil, destacando a importância da Atenção Primária à Saúde para essas finalidades.

Determination of Vs_30 from existing geophysical investigation data
Authors: Ranguelov Boyko , Borg Ruben Paul , Spassov Edelvays , Shadiya Fathimath , Frantzova Antoaneta
Published: March 2023

The Vs_30 refers to the velocity of transversal seismic waves in the upper earth crust (surface shallow depths) in the 0-30 m interval. This parameter reflects the integral ground properties and is used in almost all seismic hazard assessment software. The determination of Vs_30 is important, especially in the case of urban territories, where in-situ measurements are very difficult and sometimes impossible due to dense urban areas, large anthropogenic noise and the need of expensive boreholes. The paper presents a methodology for extracting necessary data and information from archival sources, mainly geophysical measurements frequently executed for different prospecting purposes. The methodology for assessment of the integral values of Vs_30 is proposed for the definition of seismic hazard maps in Bulgaria. The methodology proposed, based primarily on archive data, represents an effective approach with significant results, especially for the intensive urbanized town territories located in high seismic areas.

Conducta médica frente al diagnóstico prenatal de trisomía 18: ¿se aproxima un cambio de paradigma?
Authors: Grimaux Guadalupe , Páez Gustavo
Published: March 2023

El objetivo del trabajo es analizar dos conductas médicas opuestas en la vida prenatal de los niños con trisomía 18: el aborto y los cuidados paliativos perinatales. Se realizó una búsqueda bibliográfica en PubMed a partir de los términos “trisomy 18”, “abortion” y “palliative care”. Actualmente, están cambiando las conductas médicas dirigidas a los niños nacidos con trisomía 18, debido a que ya no se la considera una enfermedad incompatible con la vida. Este cambio de paradigma en la conducta médica posnatal debería reflejarse en la conducta prenatal, para ofrecer a los padres alternativas distintas al aborto. Los cuidados paliativos fetales y perinatales constituyen una respuesta ética válida para el tratamiento de niños con trisomía 18.

Published: March 2023

Agriculture plays a significant role in the economic sector in Limpopo province in terms of its contribution to the economy, and the number of employment opportunities it produces within local communities. The majority of people involved in agricultural practices are emerging farmers and smallholder/small scale farmers. The aim of the study was to determine and profile factors influencing production and market participation among smallholder tomato growers in Madibong and Manganeng Villages, Makhuduthamaga Municipality in Greater Sekhukhune District, South Africa. A purposive sampling technique integrated with a random sampling technique were used to collect primary data from 100 smallholder tomato farmers using structured questionnaires. The Multiple Linear Regression and the Logistic Regression models were used to analyse the socio-economic factors that influence tomato production and market participation among smallholder tomato farmers in the study area. The results of the study revealed that extension access, fertiliser application, marital status, income from production and use of agricultural equipment positively influence tomato production. While, the educational level, gender of the farmer, farming experience, marital status and farm size positively influence market participation, market distance negatively influences market participation among smallholder tomato farmers. Based on the findings of the study, it is recommended that there should be a comprehensive producer support programme that focuses primarily on subsidising smallholder farmers when purchasing production inputs.

Published: March 2023

A fiatalok önkéntes aktivitásának fejlesztését, vizsgálatát – mind az európai unióban, mind pedig Magyarországon – az ifjúsági és önkéntes stratégiák irányozzák elő. A tanulmány célja egyrészt, hogy bemutassa a 15-29 éves magyar önkéntes fiatalok jellemzőit, másrészt kitérjen azokra a módszertani kérdésekre, problémákra, amelyek az önkéntesség vizsgálata során felmerülnek. Mindezekből következően egyfelől ismertetem a legújabban elérhető Magyar Ifjúság 2020 adatbázisán végzett másodelemzés segítségével a hazai 15-29 éves korosztályban a magukat önkéntesnek valló fiatalok jellemzőit: áttekintve általános demográfiai, társadalmi rétegződésbeli és iskolai, valamint foglalkozási mobilitásbeli állapotukat. Másfelől az adatbázis adta lehetőségeken belül, részletesen kitérek az általuk végzett önkéntesmunka jellegének, típusának, megjelenésének elemzésére. A kutatás eredményei szerint a 15-29 évesek közül mindössze 8 százalék végzett önkéntességet a kérdezést megelőző egy évben, míg korábbi kutatások ennél inkább háromszor, de akár ötször nagyobb arányokat is kimutattak már. Ezt az ellentmondást értelmezve és magyarázva a tanulmány második részében az elmúlt másfél évtized önkéntes kutatásaira támaszkodva kitérek az ifjúság körében (vagy őket is érintő) önkéntességet (is) mérő kutatások módszertani megközelítéseire, rámutatva, hogy vélhetően nem az önkéntesek aránya ingadozott számottevően, hanem a kérdésfeltevés módszertanára érzékeny egyes válaszadók képlékeny önkéntesidentitása.

Routine clinical investigations in the memory clinic may identify a degree of cognitive impairment that does not reach threshold criteria for a dementia diagnosis. A mild cognitive impairment may be the beginnings of a progressive decline for some people. How should services respond to those people, for whom a MCI is the beginning of a progressive decline and ensure a timely diagnosis is ultimately provided? This article describes our attempt at a solution.
Experimental Device Design and Load Test of PDC Single Cutter Scraping Considering Cyclotron Motion
Authors: Ren Xinyu , Yang Yingxin , Niu Shiwei
Published: March 2023

The rotary motion of the bit caused by the lateral force imbalance of the bit leads to premature failure of the bit, mainly because the side of the cutter makes contact with the rock and participates in breaking rock. The rotating motion of the bit causes the bit to form an irregular spiral bottom hole.A lot of research and experiments have been done to eliminate the cyclotron phenomenon. However, whether it is conventional PDC cutter or special-shaped PDC cutter single cutter rock breaking experiment simulation or laboratory experiment, it is based on the way of replacing circular cutting of cutter with linear scraping, and almost does not consider the radial scraping motion of cutter under circular motion, which is still different from the actual working state of the bit. Therefore, in order to further understand the rock breaking characteristics of the cutter under irregular or circular motion, it is necessary to carry out a single rock breaking study considering the combined circumferential and radial scraping motion.
Analysis of Sealing Performance of Cone Reamer
Authors: Li Bing , Ji Yafei
Published: March 2023

When the cone reamer is working, the upper end face of the piston contacts the drilling fluid. The sealing structure is used to isolate the drilling fluid at the upper and lower end faces of the piston, thus ensuring the differential pressure between the upper and lower end faces, so as to realize the axial downward movement of the piston. The sealing between the piston and the body will have a direct impact on the expansion quality of the reamer, and affect the subsequent reaming quality. At the same time, the seal ring may be squeezed into the gap between the body and the piston during the dynamic sealing process, resulting in. Therefore, this section carries out simulation analysis on the sealing structure, discusses its sealing performance and optimizes the structure.

Analysis and Correction of Precipitation Observation Error in Henan Province
Authors: Zhang Puning
Published: March 2023

Accurate precipitation data is the basis for studying regional hydrological cycle and climate change, and correcting the precipitation observation error can effectively improve its accuracy. Therefore, based on the daily observation data (including snow and rain types) of 111 meteorological stations in Henan Province from 1960 to 2017, the precipitation observation error correction equation obtained from the precipitation error comparison observation experiment conducted in the Urumqi River Basin of China in the International Cooperation Project on Solid Precipitation Observation carried out by the World Meteorological Organization in 1980 was used to systematically correct the dynamic loss, wetness loss and trace loss of precipitation at 111 meteorological stations from 1960 to 2017. The main conclusions are: (1) The absolute error of each season decreases from south to north, the average absolute error in summer is the largest, 47.30mm, and the winter is the smallest; while the relative error is the opposite, the largest in winter and the smallest in summer. (2) The absolute error of the average annual precipitation in the entire region is above 60mm, gradually increasing from north to south, and the error in most areas is 70-160mm; The relative error varies little from region to region, and the error range is 10%-16%. (3) The average annual rainfall before the correction was 761.92mm, and the average annual rainfall after the correction was 881.1mm, and the corrected value was 119.18mm. There was a decreasing trend in rainfall before and after the correction from 1960 to 2017, but the trend of reduction in the revised rainfall series was greater than that in the measured series.

Authors: Li Deshen , Yang Hai
Published: March 2023

With the development of current information technology, it has become a common demand to obtain accurate location information quickly. However, in the indoor environment where people generally live, GPS signals are partially occluded, and the INS of inertial navigation system will significantly increase the error due to the integral accumulation error. In view of the problems of poor robustness and low accuracy of the existing loose combination positioning methods, a GPS/INS/WIFI personnel tight combination positioning method was proposed by using the WIFI network signals with wide coverage at present. Firstly, the characteristics of WIFI positioning technology were analyzed, and the INS positioning error model was established. The measurement equation under tight coupling was established by using the pseudo range value of GPS and the RSSI parameters of WIFI system, and the state equation was established by using the INS error model, so as to realize the establishment of the combined GPS/INS/WIFI positioning state space equation. Then, based on unscented Kalman filter theory, a GPS/INS/WIFI based compact combined position solution model is established. Finally, the human wearable combined positioning experiment platform was used for experimental verification. The experimental results show that the GPS/INS/WIFI based tight combined positioning method can significantly adapt to the indoor environment with complex interference, has high positioning stability and positioning accuracy, and the maximum positioning error is 0.45m. Compared with the extended Kalman filter and Kalman filter, the positioning accuracy of unscented Kalman filter is improved by 56% and 89% respectively, which can meet the requirements of field use.

Discussion on the Necessity of Soil Organic Carbon Mineralization in Degraded Forest Land in Aeolian Sand Beach Area
Authors: Meng Tingting , Wang Xue
Published: March 2023

Soil organic carbon is the largest carbon pool in terrestrial ecosystem, and its dynamic change is an important factor affecting the carbon budget balance of terrestrial ecosystem and the global carbon cycle. The forest land is extremely sensitive to the change of soil carbon pool. The wind-sand beach area in the north of Jingbian is located at the southern tip of the Mu Us Desert, and the ecological environment is fragile. The shelterbelt has been seriously degraded and fragmented, forming a large area of fragmentated forest, which has gradually changed from the original carbon sink into a carbon source. In addition, this region is dry, less rain and more wind-blown sand, which determines that temperature and moisture are the key factors affecting the mineralization and stability of soil organic carbon in this region. This paper analyzed and summarized the influencing factors of soil organic carbon mineralization, such as water, temperature and organic carbon components, and discussed the necessity of studying soil organic carbon mineralization in degraded forest land.

Published: March 2023

While the manufacturing process of ceramics is complex and each link is important to the ceramic, we focus on the sintering process of ceramics and construct models and algorithms to investigate the temperature of the ceramic sintering process in order to improve the yield of the ceramic sinter. We make full use of the ceramic sintering process node temperature and ceramic product problem data, adopt factor analysis for data dimensionality reduction, and use principal component analysis to extract factors to improve efficiency for subsequent optimisation. The random forest algorithm of integrated machine learning is used to investigate the effect of different nodal temperature rates on the ceramic product, and a decision tree is derived to identify the more influential temperature rates. These obtained important temperature factors affecting ceramic sintering can be used as a reference for the ceramic sintering process, thus achieving a study of the temperature of the ceramic sintering process.

Authors: Chen Jiazhao , Wang Xueren
Published: March 2023

The paper, by experiment of physical simulation, researched the leakage and diffusion law of N2O4 in a specific closed space. To simulate N2O4 leakage, the experiment pumped a certain amount of N2O4 gas into a specific space from a simulated leak point. And some electrochemical sensors were used to detect the concentration of N2O4 gas in some places in the space. The result showed that N2O4 diffused in the space, and the sensors facing to and near to the leak point sensed N2O4 gas at first. In the beginning, N2O4 diffused faster in the places below than above, and the bigger the leakage amount, the higher the concentration. After a while, N2O4 gas got even by diffusion, and the bigger the leaked amount was, the bigger the even concentration. If the environmental temperature was high, the even concentration in the lower part was higher a bit than that in the upper part. And the specific distribution of concentration was decided by the shape of the space.
