Published: November 2024

This study aims to examine the influence and extent of the impact of price and product reviews on online purchasing decisions in Shopee’s E-commerce platform, specifically among students of Sangga Buana University YPKP Bandung in 2024. The research applies a quantitative approach with a correlational research method, using multiple linear regression to analyze the data. The sample consists of 100 students and Shopee consumers who have conducted purchase transactions on the Shopee platform, selected through random sampling. Data collection was carried out via a questionnaire. Results indicate a multiple linear regression model Y=13,530+0.095X1+0.515X2Y = 13,530 + 0.095 X1 + 0.515 X2Y=13,530+0.095X1+0.515X2. The F test results suggest that all independent variables collectively do not significantly affect online purchasing decisions. Additionally, a simple linear regression model was applied as H1 was rejected, resulting in Y=14.039+0.571X2Y = 14.039 + 0.571X2Y=14.039+0.571X2. The R Square value of 0.198 signifies that price and product review variables contribute 19.8% to online purchasing decisions, while the remaining 80.2% is influenced by other unexamined factors.

Retail companies play an important role in the global economy by meeting the daily needs of consumers. During the general economic crises, these companies demonstrate relatively smaller «setbacks» compared to the market, but, on the other hand, such a factor of stability is also a certain limiter of growth. Therefore, it is very common for companies to collaborate with each other, creating business collaborations to expand their market and achieve joint growth and success. The aim of the study is to develop and implement an algorithm for finding partners for collaboration. The proposed algorithm contains the following steps: formation of the research information base; preliminary statistical analysis of the generated dataset; classification of objects in the multifactorial feature space; assessment of the quality of classification; substantive analysis of the obtained classification; ranking objects within the cluster group and selecting candidates to create a collaboration. The algorithm is implemented for the output dataset of companies in the retail sector, which were part of the SP500 index as of the beginning of August 2024. The initial dataset contained information on the values of such financial and economic indicators as: dividend income, price/net profit ratio, return on assets, return on equity, profit margin, debt-to-equity ratio, price/revenue multiplier, price/money flow multiplier, price/book value multiplier, share of equity capital, current liquidity ratio. The implementation of the algorithm allows you obtaining a quantitative assessment of the suitability of the analyzed company for participation in the collaboration. Such a quantitative assessment is obtained as a result of the implementation of machine learning algorithms, namely, the k-medoids algorithm, which allows classifying the objects of study into relatively homogeneous groups, as well as identifying a representative of each group, whose coordinates play the role of a cluster centroid.

Published: December 2024

The aim of the article is to study and analyze the current state of foreign economic activity of enterprises and determine the impact of the ongoing full-scale aggression on trade and economic relations between Ukraine and the countries of the European Union. Analysis, systematization and generalization of statistical data and the work of many scientists are carried out; the changes that have befallen the foreign economic structure of exports and imports of goods between Ukraine and the countries of the European Union are considered. The impact of military hostilities on the volume of production of goods and services is analyzed and described. An important component of Ukraine’s integration into the European Union is the economic component. With the countries of Eastern Europe, which are part of the European Union, our country shares common borders, history, habits, etc. It is borders that are an important component of trade activity and its complete reformatting during aggression by another State. Therefore, the countries of the European Union have now become the main trading partners of Ukraine. The article compares the volumes of imports and exports of goods and services in 2021, before the full-scale war, and the indicators of 2022 and 2023. A drop in exports of goods by 12.7% and an increase in imports by 12.2% are detected. The influence of military factors on foreign economic activity in the sectors of trade in goods and services is also studied. These factors have a direct and immediate impact on the economy of Ukraine, so they directly affect Ukrainian foreign economic activity. Such factors include: the geography of hostilities, migration of the population, the occupation of part of the territories, war crimes, namely, strikes on electricity generating capacities, and more. These factors have completely changed the structural component of Ukraine’s economic activity and its cooperation with the countries of the European Union. The conclusions of this study can be used in the future to analyze and develop strategies for the post-war development of economic activity aimed at the European integration of Ukraine.

PARAMETRIC ANALYSIS OF ENERGY EFFICIENCY IN DOUBLE SKIN FAÇADES FOR HOT AND DRY CLIMATES: A CASE STUDY OF KEBBI STATE, NIGERIA
Authors: Wurma Gambo Bara'u , Muhammad Abdulsalam Abdullahi
Published: November 2024

This research evaluates the energy and concepts of Double Skin Façades, which were established through computational simulations integrated with some relevant examples. DSF is regarded as one of the best solutions in realizing the interface between the interior and the exterior building spaces. It also allows provides architectural flexibility in the design. Recently, the double-skin façade has received much attention as opposed to the more typically glazed curtain wall. This is for its ability to effectively reduce the thermal transmission (U-value) and solar heat gain (G-value). DSF design comprises assessments of building geometric factors, glazing type, ventilation procedures, shading devices, daylighting aesthetics, and maintenance expenses. However, the concept of DSF is sometimes complicated, and its use and function influence different parameters of the building, but if the approach is overall and the aims to be realized are distinct, then the stated method is flexible enough to reach climatic variations for the greatest types of building use. Besides the fact that large number of researches carried out on the performance of this facade configuration in moderate climates, it is very vital to recognize its performance and viable formations in hot and dry climates. It is therefore a chance to learn about this facade arrangement earlier the technology is transmitted into construction in hot arid areas. Results of the analysis revealed that variation in value by certain degrees and alteration of some parameters has a direct effect in the energy use intensity as well as the illuminance values of an office building...
Asymmetric effects of exchange rate and oil price on export performance and economic growth in WAMZ
Authors: Sanusi Kazeem Abimbola , Kapingura Forget Mingiri
Published: November 2024

The purpose of the study is to explore the effects of exchange rate and oil price asymmetries on export performance and economic growth in the West African Monetary Zone (WAMZ). The study uses monthly data from 1970 to 2022. The study makes use of the asymmetric ARDL approach. Our findings show that there exists a long-run relationship between oil price, exchange rate, export performance, and output growth. We find that depreciation of the exchange rate and increases in oil prices generally hinder the economic prospects of these nations. Furthermore, it was found that currency depreciation did not significantly improve the export performance of these nations, primarily due to the largely stagnant manufacturing sectors and other challenges such as infrastructural decadence that these nations face. The findings imply that these countries, as well as the rest of Africa, still need to implement sincere and significant economic changes. We need to make large-scale investments in infrastructure development, revive the dormant manufacturing sector, actively and transparently combat corruption at all levels, and take other actions to stabilize their currencies and boost export performance, all of which will contribute to economic prosperity. We also recommend a strong institutional framework that will strengthen and support the effective policy outcomes.
Bir Bürokratik Bağımlılık Örneği: Niẓāmülmülk ve Ailesi
Authors: Yazar Nurullah
Published: November 2024

Dünya tarihine damga vuran devletler incelendiğinde güçlerinin zirvesine çıktıkları dönemlerde muktedir hükümdarların başta olduğu görülür. Devletin yegane yöneticisi konumunda kabul edilen bu hükümdarlar ile devletin sahip olduğu güç özdeşleştirilir ve hükümdarlar kudretli simalar olarak görülmeye başlanır. Bununla birlikte yüzeysel okuma ve anlatılardan daha derine inildiğinde hükümdarın başarısının arka planında adı bilinen ancak yaptıklarının farkında olunmayan güçlü devlet adamları görülecektir. Bu isimlerden birisi de Niẓāmülmülk lakabıyla meşhur Ebū ʿAlī Ḳıvāmuddīn Ḫasen b. ʿAlī b. İsḥāḳ et-Ṭūsī’dir (ö. 485/1092). Bürokratik görevine Gazneliler’in Horasan Valisi Ebū’l-Faḍl es-Ṣūrī’nin yanında başlayan Niẓāmülmülk, Dandanakan Savaşı (1040) sonrasında hizmetlerine Büyük Selçuklu Devleti’nde devam etmiştir. Niẓāmülmülk’teki potansiyeli gören Çağrı Bey, huzuruna gelen Niẓāmülmülk’e oğlu Alparslan’ı teslim etmiş, Alparslan’a da Niẓāmülmülk’ü bir baba olarak kabul etmesini ve ona muhalefet etmemesini öğütlemiştir. Merv’de başlayan Selçukluya hizmet, Alparslan’ın Selçuklu tahtına geçmesiyle birlikte vezirlik makamında devam etmiştir. Önce Alparslan sonrasında da Melikşah dönemlerinde yaklaşık 30 yıl kesintisiz bir süreyle Büyük Selçuklu Devleti’nin vezirliğini yapan Niẓāmülmülk, Malazgirt Zaferi hariç, Selçuklu tarihinin en önemli olaylarında yer almış ve karar mercii olmuştur. Sergilediği başarılı vezaret Niẓāmülmülk’ü vazgeçilmez bir isim haline getirmiştir. Tarihin gördüğü en kudretli devletlerden birisi haline gelmesinin ardından Büyük Selçuklu Devleti’nin en büyük talihsizliği iki güçlü figürünü peş peşe kaybetmesidir. Önce kudretli vezir Niẓāmülmülk’ün, kısa bir süre sonra da Sultan Melikşah’ın vefatıyla girilen fetret döneminden çıkış arayışlarında Selçuklu hanedan üyelerinin ilk çözüm yolu güçlü bir vezir bulmaktı. Taht müddeilerinin kendi Niẓāmülmülk’lerini bulmak için ilk baktıkları yer Niẓāmülmülk’ün evlatları olmuştur. Biz de çalışmamızda Niẓāmülmülk’ün Büyük Selçuklu yönetiminde görev alan çocuk ve torunlarına odaklanıp Selçuklu tarihindeki yerlerini tespit etmeye çalışacağız. Böylece Niẓāmülmülk’ün Selçuklu Devlet bürokrasisindeki gücünü kendi ellerinde toplayabilecekleri düşüncesiyle onun soyundan gelenlere devlet kademesinde görev verildiği tespitini paylaşacağız. Netice olarak da varsayımlarla hareket ederek atılan siyasi adımların her zaman hedeflenen sonuca götürmediği sonucunu ortaya koyacağız.

Ineffective erythropoiesis (IE) is defined as the abnormal differentiation and excessive destruction of erythroblasts in the marrow, accompanied by an expanded progenitor compartment and relative reduction in the production of reticulocytes. It is a defining feature of many types of anemia, including beta-thalassemia. GATA1 is an essential transcription factor for erythroid differentiation, known to be implicated in hematological conditions presenting with IE, including beta-thalassemia and congenital dyserythropoietic anemia. However, little is known about the role of GATA1 in the erythropoietic defects recently described in sickle cell anemia (SCA). In the present study, we performed a detailed characterization of the role of GATA1 and ineffective erythropoiesis in SCA using both invitro and in-vivo assay systems. We demonstrate a significant decrease in GATA1 protein levels during SCA erythropoiesis and a concomitant increase in oxidative stress. Furthermore, we found that an increase in the activity of the inflammatory caspase, caspase 1, was driving the decrease in GATA1 levels during SCA erythropoiesis and that, upon inhibition of caspase 1 activity, SCA erythropoiesis was rescued and GATA1 levels partially restored. Our study further elucidates the defect in erythropoiesis in SCA, and may therefore help in the development of novel approaches to normalise the bone marrow niche prior to stem cell transplantation, or facilitate the production of healthy stem cells for gene therapy.

Simulación Geometalúrgica para la Exploración de Ocurrencias Minerales de Oro y Plata
Authors: Alvarez Miguel , Ramos Nelson , Ramos Diego , Calderón-Celis Marilú
Published: November 2024

La exploración de recursos constituye una etapa importante para localizar elementos de interés económico, sin embargo, tradicionalmente solo se evalúan indicadores geoquímicos sin considerar variables que impactan en la cadena de valor de la minería. Por consiguiente, el objetivo de esta investigación consistió en elaborar la simulación geometalúrgica para la exploración de ocurrencias minerales de Au y Ag, mediante información geo-estructural, geoquímica y atributos geometalúrgicos de una zona prospectiva ubicada al NW de Ecuador. Para esto se aplicó el Análisis Composicional a datos geoquímicos de 37 elementos en 448 muestras de sedimentos fluviales, y se conformaron dos grupos multielementales, para indicadores geoquímicos de Au – Ag y otro de perjudiciales en lixiviación. Luego, se elaboró su análisis geoestadístico mediante Simulación Secuencial Gaussiana, ejecutando 100 realizaciones para cada grupo y se eligieron aquellas que reproduzcan mejor las estadísticas y variogramas. Además, se evaluó la probabilidad de ocurrencia por encima del valor umbral. Los resultados anómalos son coherentes con datos de depósitos cercanos que indican una ley de 57.45 g/t Au y recuperación mayor al 90 %; asimismo, existen zonas con alta probabilidad (> 50 %) de ocurrencias de elementos perjudiciales, lo que probablemente afecte negativamente en la recuperación de Au a gran escala. Dada la fuerte correlación entre anomalías geoquímicas con presencia de cuerpos intrusivos, sistemas estructurales de fallas y datos metalúrgicos, se establece una nueva metodología para labores prospectivas que permite definir áreas más precisas para la exploración a detalle, lo cual reduce el riesgo e incertidumbre en etapas iniciales de la minería.
Rate-dependent deformation behaviour of porous sandstones at reservoir conditions: An experimental, numerical and microphysical study
Authors:   , Shinohara Takahiro
Published: November 2024

Extraction of fluids, like oil/gas or geothermal fluids, from the Earth’s crust (1-5 km depth) often leads to surface subsidence and tremors, such as observed in the Dutch Groningen Gas Field. Fluid production leads to reduced fluid pressure in the pores of the reservoir. Together with the weight of the overlying rock this causes the reservoir to compact slightly, resulting in surface subsidence. While reservoir compaction is often assumed to be fully reversible, a substantial portion of compaction has been shown to be permanent and may even be time-dependent, meaning it may continue temporarily even if production is stopped. To reliably evaluate reservoir behaviour after fluid extraction has stopped, it’s key to understand the physical processes that occur within the rock causing compaction.

In my work, I performed laboratory experiments and numerical simulations on various porous sandstones, deformed under conditions relevant to typical gas fields, to identify these processes. Results show that after production is stopped, some limited reservoir compaction may still occur, caused by slow, time-dependent breakage of grains, coupled with grain slip along clay-coated contacts. When lateral displacements are restricted, such as is the case in the crust, compaction is further limited. These observations highlight the importance of including such subtle, grain-scale deformations in models used to assess reservoir deformation. With the energy transition becoming increasingly pressing, this is also relevant to geological storage of CO2, and energy storage (hydrogen, compressed air), which aim to curb anthropogenic CO2 emissions and provide a stable, renewable energy supply.

Authors: Contreras Gatica Yasna , Seguel Calderón Beatriz
Published: November 2024

Se plantea el término violencia interterritorial contra mujeres inmigrantes (VIMI) como una lectura espacial del continuum de violencias sufrido por mujeres migrantes de la región latinoamericana y del Caribe en su viaje y estadía en Chile. Adoptando el término teórico-metodológico de trayectorias migratorias,se analizan testimonios de 30 participantes para indagar la construcción espacio-temporal de su movilidad, alimentada por relatos biográficos. La VIMI refleja su tránsito por regiones con expresiones de violencia que traspasan el territorio de nacimiento, tránsito, espera y permanencia, además de toda frontera político-administrativa. Esta lectura interterritorial de la violencia expone cómo la condición compuesta de mujer-migrante en los territorios habitados determina un posicionamiento particular frente a espacios altamente masculinizados. Concluimos que la VIMI es un aporte a la construcción de políticas migratorias regionales que reconozcan estas violencias y p

Published: November 2024

O artigo aborda a constituição da ideia de arqueologia tecnológica na área de gravura e sua fundamentação como processo metodológico no contexto pesquisa-ensino. Assim, consideramos em retrospecto a forma como essa noção passa a integrar as ações acadêmicas e artísticas na Faculdade de Belas Artes da Universidade do Porto (FBAUP), partindo da constatação de que certos processos gráficos, sequer são introduzidos em espaço oficinal, seja por um apagamento sistemático e histórico, seja pela pouca apetência em fazer correlações com processos usados em caráter comercial, industrial e/ou artesanal em detrimento de uma tradição dogmática ainda presente nas artes.

Published: November 2024

Neste artigo é proposta uma investigação sobre a relevância da gravura na arte contemporânea, em diálogo com outros autores, analisando traços da sua trajetória histórica e sua relação com outras artes e mídias. Iniciando pela análise da gravura no contexto da cultura impressa, são exploradas sua inserção na arte contemporânea, marcada pela pós-disciplinaridade, onde a gravura e as artes impressas têm se tornado cada vez mais onipresentes na arte global, estabelecendo diálogos complexos com outras linguagens artísticas, como a fotografia, a videoarte e as instalações. Sem a pretensão de esgotar o tema, são feitas algumas reflexões sobre questões como a ubiquidade, a invisibilidade da gravura e a “morte do impresso; o mundo artístico pós-mídia/pós-disciplinar/pós-impresso; relação entre a gravura e as novas tecnologias; características da gravura como contato, reversão, repetição e disseminação; redefinições da gravura e suas contaminações e o campo ampliado da gravura. A relação da gravura com outras artes e mídias tem sido fundamental para a sua revitalização, expandindo seus limites e consolidando seu papel na arte contemporânea.

MEMÓRIA VISUAL NA ERA DIGITAL
Authors: Pagatini Rafael
Published: November 2024

O artigo explora o processo de desenvolvimento da obra Manipulações (2016), criada pelo autor, analisando a interação entre imagens digitais e analógicas, com ênfase na memória visual relacionada à ditadura militar no Brasil e às Jornadas de Junho de 2013. Utilizando a técnica da xilogravura, a obra transforma uma imagem digital de baixa resolução, extraída do Facebook, em um objeto físico, destacando as tensões entre a efemeridade do digital e a permanência do analógico. Inspirada pela teórica e artista Hito Steyerl, que descreve certas imagens contemporâneas como "cópias em movimento" que perdem qualidade à medida que circulam amplamente, Manipulações explora essa degradação, ressignificando as imagens por meio de sua materialização. A obra também problematiza o papel dos algoritmos das redes sociais na construção da memória visual, revelando como essas plataformas filtram e priorizam determinadas narrativas, enquanto outras são marginalizadas. Ao evocar práticas de resistência visual e conectá-las às técnicas tradicionais da gravura, Manipulações questiona as narrativas dominantes e sugere novas formas de engajamento afetivo e crítico com a história. A obra busca assim não apenas preservar, mas também transformar as narrativas visuais, demonstrando a relevância contínua da gravura como meio de expressão na era digital. Em última instância, Manipulações busca contribuir para um imaginário cultural mais amplo e inclusivo, capaz de acolher múltiplas vozes e reconfigurar as narrativas visuais contemporâneas.
Navigating an uncertain interregnum
Authors: Boland Neil
Published: December 2024

This article seeks to identify trends in Steiner Waldorf education through the lens of Clarence Beeby’s work on educational myths. Beeby calls myths a form of communication between contemporaries or between generations, ways of conceptualizing education that can be understood quickly yet are flexible enough to accommodate a range of interpretations. A myth holds for a period and then transitions into a new myth that best suits changed times and changed circumstances. I reflect on what the myths of Waldorf education might be and take up Gramsci’s well-known quotation on change, “The crisis consists precisely of the fact that the old is dying and the new cannot be born; in this interregnum a great variety of morbid symptoms appear,” In writing this, Gramsci extended the interregnum beyond its usual papal connotation to include the socio-cultural condition as well. I use the notion to consider if Waldorf education is currently in an interregnum period and is displaying both “morbid symptoms” and promising signs of fresh development. In addition, I contemplate if these promising signs point toward a new myth that will allow Waldorf education to step beyond its century-old, colonial heritage.

Alzheimer’s disease (AD) is a neurodegenerative disorder that severely impacts cognitive function, posing significant physical and psychological burdens on patients and substantial economic challenges to families and society, particularly in aging populations where its prevalence is rising. Current diagnostic and therapeutic strategies, including pharmacological treatments and non-pharmacological interventions, exhibit considerable limitations in early diagnosis, etiological treatment, and disease management. This study aims to investigate the application of artificial intelligence (AI) in the early diagnosis and progression monitoring of AD through a bibliometric analysis of relevant literature. A systematic search in the Web of Science Core Collection identified 530 publications related to AI and AD, consisting of 361 original research articles and 169 review articles, with a notable increase in annual publication rates, particularly between 2019 and 2024. The United States and China emerged as leading contributors, emphasizing the importance of international collaboration. Institutional analysis revealed that Harvard University and Indiana University System are at the forefront, highlighting the role of academic institutions in fostering interdisciplinary research. Furthermore, the Journal of Alzheimer’s Disease was identified as the most influential publication outlet. Key highly cited papers provided essential theoretical foundations for ongoing research. This study underscores the growing relevance of AI in AD research and suggests promising avenues for future investigations, particularly in enhancing diagnostic accuracy and therapeutic strategies through advanced data analytics and machine learning techniques.

Background

Programmed cell death protein 1 (PD-1) inhibitors are commonly used worldwide for the management of non-small cell lung cancer (NSCLC). However, it remains unclear whether pembrolizumab and sintilimab, two of the most widely used PD-1 inhibitors in China, have significantly different effects on patients with NSCLC. A multicenter retrospective cohort study was designed and implemented using propensity-score matching (PSM) analysis to compare the effectiveness and safety profiles of pembrolizumab and sintilimab in patients with advanced NSCLC undergoing comprehensive therapy.

Methods

A total of 225 patients who received comprehensive therapy including pembrolizumab (n = 127) or sintilimab (n = 98), from 1 January to 31 December 2020 and met the eligibility criteria were included. PSM analysis (1:1) was performed to balance potential baseline confounding factors. For both treatments, Kaplan–Meier analysis and Cox regression were used to compare 1-year progression-free survival (PFS), disease control rate (DCR), objective response rate (ORR), and rates of all adverse events (AEs).

Results

PSM analysis resulted in 63 matched pairs of patients. After PSM, the median PFS was 8.68 months in the sintilimab group and 9.46 months in the pembrolizumab group. The 1-year PFS showed no significant difference between the pembrolizumab and sintilimab groups before and after PSM (P = 0.873 and P = 0.574, respectively). Moreover, within the matched cohort, the pembrolizumab group had an ORR of 30.2% and a DCR of 84.1%, whereas the sintilimab group exhibited an ORR of 41.3% and a DCR of 88.9%. There were no significant differences in the ORR and DCR between the two groups (P = 0.248 and P = 0.629, respectively). The incidence of grade 3 or 4 treatment-related AEs was significantly higher in the pembrolizumab group than that in the sintilimab group (42.9% vs. 33.3%, P = 0.043). Multivariable Cox proportional hazards regression analysis indicated that the lines of treatment and regimens significantly influenced the PFS of patients (P <0.05).

Conclusions

This study demonstrated the similar effectiveness of sintilimab and pembrolizumab in the treatment of patients with advanced NSCLC, with sintilimab potentially displaying a superior clinical safety profile.

A review on functional lung avoidance radiotherapy plan for lung cancer
Authors: Yu Jinhui , Tang Xiaofeng , Lei Yifan , Zhang Zhe , Li Bo , Bai Han , Li Lan
Published: December 2024

Lung cancer is the most common malignant tumor in China. Its incidence and mortality rate increase year by year. In the synthesis treatment of lung cancer, radiotherapy (RT) plays a vital role, and radiation-induced lung injury(RILI) has become the major limiting factor in prescription dose escalation. Conventional RT is designed to minimize radiation exposure to healthy lungs without considering the inhomogeneity of lung function, which is significantly non-uniform in most patients. In accordance with the functional and structural heterogeneity of lung tissue, functional lung avoidance RT (FLART) can reduce radiation exposure to functional lung (FL), thus reducing RILI. Meanwhile, a dose-function histogram (DFH) was proposed to describe the dose parameters of the optimized image-guided RT plan. This paper reviews lung function imaging for lung cancer RT plans. It also reviews the clinical applications of function-guided RT plans and their current problems and research directions to provide better guidance for clinical selection.

Published: December 2024

Background

Distant metastasis of gastric cancer can seriously affect the treatment strategy of gastric cancer patients, so it is essential to identify patients at high risk of distant metastasis of gastric cancer earlier.

Method

In this study, we retrospectively collected research data from 18,472 gastric cancer patients from the SEER database. We applied six machine learning algorithms to construct a model that can predict distant metastasis of gastric cancer. We constructed the machine learning model using 10-fold cross-validation. We evaluated the model using the area under the receiver operating characteristic curves (AUC), the area under the precision-recall curve (AUPRC), decision curve analysis, and calibration curves. In addition, we used Shapley’s addition interpretation (SHAP) to interpret the machine learning model. We used data from 1595 gastric cancer patients in the First Hospital of Jilin University for external validation. We plotted the correlation heat maps of the predictor variables. We selected an optimal model and constructed a web-based online calculator for predicting the risk of distant metastasis of gastric cancer.

Result

The study included 18,472 patients with gastric cancer from the SEER database, including 4,202 (22.75%) patients with distant metastases. The results of multivariate logistic regression analysis showed that age, race, grade of differentiation, tumor size, T stage, radiotherapy, and chemotherapy were independent risk factors for distant metastasis of gastric cancer. In the ten-fold cross-validation of the training set, the average AUC value of the random forest (RF) model was 0.80. The RF model performed best in the internal test set and external validation set. The RF model had an AUC of 0.80, an AUPRC of 0.555, an accuracy of 0.81, and a precision of 0.78 in the internal test set. The RF model had a metric AUC of 0.76 in the external validation set, an AUPRC of 0.496, an accuracy of 0.82, and a precision of 0.81. Finally, we constructed a network calculator for distant metastasis of gastric cancer using the RF model.

Conclusion

With the help of pathological and clinical indicators, we constructed a well-performing RF model for predicting the risk of distant metastasis in gastric cancer patients to help clinicians make clinical decisions.
