AbstractLearning to pray at RA Miftahul Ulum Ngemplak is taught not so optimally. This can be seen from the movement of students there is still something wrong when asked to practice prayer. The mistakes made by students vary from the position of the hands during takbiratul ihram, the position of the feet during prostration, and errors in the sequence of prayer movements. In addition, when learning prayer, students tend to be less interested. The lack of stimulation that has not been able to attract the attention of students has resulted in reduced motivation to learn to pray. The purpose of this study is to improve students' prayer learning skills through serial image media at RA Miftahul Ulum Ngemplak for the 2020/2021 academic year. The research method used is classroom action research (CAR). This research was conducted in an odd semester starting from October 12, 2020 to October 28, 2020. The subjects of this study were the RA group, which consisted of 20 children consisting of 12 boys and 8 girls.Keywords: Early Childhood, Learning to pray, picture series.AbstrakPembelajaran shalat di RA Miftahul Ulum Ngemplak diajarkan belum begitu maksimal.

The purpose of the research is to establish the need for maintenance logging in artificial 16-19-year-old plantings of various compositions using a comprehensive evaluation indicator. The purpose of the research work is to increase the durability of artifi cially created plantings in the study area based on the improvement of methods of logging maintenance. The data obtained will make it possible to assess the effectiveness of forestry measures. The species composition of the green zone of the city of Nursultan is mainly represented by plantings of elm, ash-leaved maple, tree willow, narrow-leaved loch, warty birch, common pine. There are practically no practical recommendations for carrying out forestry care for these species growing in the steppe zone, the subzone of dry tipchak-kovyl steppes with a sharply continental climate. Work on the study of the impact of logging care in plantings of various formations of the green zone of the city of Nursultan has not been carried out before, which determines the scientifi c novelty of the project. The practical signifi cance of the work is that the results obtained can be used to predict the growth and productivity of plantings in similar forest growing conditions.
Safety of operation of the fastening plates of the downstream

Published: March 2022

The purpose of the research was to study the conditions for maintaining the stability of the fastening plates under the infl uence of the hydrodynamic load in the downstream, ensuring the safety of its operation. Emergency situations at hydraulic structures often occur due to the loss of stability and subsequent destruction of fastening plates in the downstream of structures, which require signifi cant costs for their reconstruction. Ensuring the reliability and safety of the fastening plates of the downstream of hydraulic structures is closely connected with their stability during operation. The main reason for destruction of the fastening plates of the hearth and apron is the effect of the hydrodynamic load on them during the operation of the hydraulic structure. The methods for calculating the structures of the downstream fastening, providing for the weighting of the fastening plates, do not fully guarantee their stability and safety. The internal structure of prefabricated fasteners, where individual elements are connected by fl exible ties, allow their insignifi cant vertical and angular displacements and create the possibility of some deformation of the fastening without destruction. The process of vertical displacements of fastening plates in the period of their oscillations under the infl uence of a hydrodynamic load, described by a second-order linear differential equation with variable coeffi cients and a random right-hand side, is considered. The method of numerical solution of the equation is applied. It was found that the mathematical expectation of the position of the slab is practically independent of the ratios of the natural vibration frequency of the fastening plates and the driving frequency of the load pulsation, as well as the variation of the damping coeffi cients. The research results make it possible to change the approach to the design scheme of fastening plates during design, to make a forecast of the state of stability of the fastening plates depending on the current hydrodynamic load, and to identify the moment of loss of stability.

The paper presents the results of theoretical and experimental substantiation of the use of injection fl ow regulators with a new form of fl ow part. A distinctive feature of the structures is a complete change in the end section of the regulator. The output cross-section of the transit water outlet is placed in the downstream and has a diaphragm with edges cut down the stream and partial lateral fl ow clamping. There is no diffuser at the end section, the output of the fl ow into the volume of the downstream takes place directly from the prismatic mixing chamber, which has a constant area. A method for theoretical calculation of hydraulic parameters of injection fl ow regulators with a diaphragm without diffuser output areas has been developed. The validity of the use of theoretical dependencies to determine the hydraulic characteristics of the structure and the effectiveness of the proposed changes in the form of the fl owing part have been proven. Injection regulators without diffusers are capable of taking up to 30% of the excess from the downstream fl ow and ensuring its circulation between the outlet section of the outlet and the mixing chamber. The increase in the regulating capacity compared to existing designs of injection water outlets is due to the optimization of the diaphragm design.
PACKING OF THE SOIL SURFACE AS A WAY TO OPTIMIZE THE HYDROTHERMAL REGIME OF THE ARABLE LAYER
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, BEKHOVYH Y. V.
Published: March 2022

The research goal was to study changes in the hydrothermal regime of the arable soil layer after packing its surface. Leached chernozem was chosen as an object for the study of the hydrothermal regime. The experimental plots were located in the climatic zone of the arid splitting steppe. The objectives of the study included: to monitor changes in soil moisture when packing its surface and to consider the impact of this agricultural technology on moisture conservation in the arable layer as well as to study the tendency of changes in the temperature regime of the arable soil layer when packing its surface and, based on this, to consider the possibility of using this agricultural technique for thermal soil reclamation. The conducted studies have shown that on the packed surface of the black steam, in contrast to the surface without packing, a noticeable layer of the dried soil is formed, which has a moisture-saving effect on the underlying layers. Reducing the parameters of the pore space of the soil and improving the conductive thermal conductivity when rolling contributes to faster warming of the soil compared to the site without rolling. The revealed features allow us to say that packing as an agricultural technology can be used to preserve moisture in the arable layer, especially in spring, as well as to increase the amount of active temperatures in the arable layer.
Changes in the water regime of the Vakhsh river in the “Tigrovaya Balka” location as a result of the construction of the Nurek and Rogun reservoirs

Published: March 2022

The purpose of the study is to evaluate the current and historical situation with water flow in the nature reserve “Tigrovaya Balka” before and after the Nurek and Rogun reservoirs and to identify the influence of the distribution of the annual runoff and sediments of the Vakhsh river below the dam ocation. The problem of protection and preservation of the unique ecosystem of the “Tigrovaya Balka” reserve becomes urgent due to the change in the water regime of the Vakhsh river. This impact began from the date of filling the reservoirs of Nurek (the late 60s of the 20th century) and its subsequent operation. The results of the data analysis are presented, which show the impact of changes in the distribution of water flow of the Vakhsh River below the dam location on the state of the reserve. The article also examines the impact of the commissioning of the reservoirs on changes in sediment discharge and water turbidity of this river in the Tigrovaya Balka section, for instance, the amount of sediment decreased by 11.3 times and turbidity 7.05 times. These led to intensive erosion of the river channel, a decrease in the water level in lakes and the level of groundwater in the reserve, a violation of long-term natural modes of sedimentation, formation, as well as the entire hydrological regime of the river in the reserve “Tigrovaya Balka”. The influence of the commissioning of the reservoirs on changes in the flow of sediments and the water turbidity of this river in the site of the “Tigrovaya Balka” is considered – the amount of sediments decreased by 11.3 times, and the turbidity by 7.05 times, which leads to the intensive erosion of the riverbed, decrease in the water level in the lakes and the level of groundwater in the reserve, violation of long-term natural regimes of sedimentation, channel formation, as well as the entire hydrological regime of the river in the “Tigrovaya Balka” reserve. To solve the above environmental problems, the article proposes solutions.
Seismic Assessment of Tall Buildings Designed According to the Turkish Building Earthquake Code
Authors: Ergunes Orhan Ilkay , Aksu Ozkul Tulay
Published: March 2022

For the first time, the 2018 edition of the Turkish Building Earthquake Code has added a dedicated chapter for the design of high-rise buildings in earthquake-prone areas. Keeping in view the widely practised design option of rigid shear walls at the centre of a high-rise structure, the latest code has additionally defined limits for shear-wall axial forces in high-rise buildings. The new shear-wall axial force limits have not been independently investigated for optimal design and criticality. This calls for a detailed investigation of the newly defined axial force limits for the design of high-rise buildings in Turkey, where seismic activity has historically remained high. This study, therefore, investigates the effect of variation in limit values of shear wall axial forces on the collapse prevention of such buildings. A high-rise building designed entirely according to the code was chosen as the base model. The location of the building is in Istanbul, which has the highest number of tall buildings as compared to other cities in Turkey. A total of 7 alternative models were created by changing the concrete material class and the thickness of shear walls. This approach allowed us to quantify the effect of shear-wall thickness and its criticality against another important design consideration, i.e., the compressive strength of concrete. Forty different earthquake ground motion records were used to analyse the models to determine how critical the axial force ratio of the shear walls is in terms of collapse probability. The method proposed in the Federal Emergency Management Agency (FEMA) document FEMA P695 was followed to determine the collapse levels for the high-rise structures. A nonlinear analysis was performed to analyse the failure safety of the models. Results indicate that an increase or decrease in the axial force ratios by more than 15% renders the structure either overdesigned or deficient. Doi: 10.28991/CEJ-2022-08-03-011 Full Text: PDF

Published: March 2022

This study aims to determine the material composition and dimensions of X-block, develop a slope reinforcement model using X-block, evaluate the mechanical behavior of slopes that are reinforced with rock-bound by X-block, and analyze the performance of slope reinforcement using X-block. This research was conducted at Hasanuddin University's soil mechanics and civil engineering structure laboratory. The model scale test was employed in this study. The geometrical speciation of the test box is 150 cm in length, 60 cm in width, and 100 cm in height. The X-block model was produced using concrete with a FC of 25 MPa. The X-block was divided into two types: X-block type 1 and X-block type 2. Tensile strength testing is performed on the X-block. The slopes are made of clay soil and have a slope angle of 70 degrees. The loading test was conducted in three stages: without block, with X-block type 1, and with X-block type 2. The loading test uses a hydraulic pump equipped with a load cell and LVDT. The tensile strength of X-block type 1 is 2.56 MPa, whereas X-block type 2 has a tensile strength of 4.35 MPa. The development of the type X-block design, which is used as a retaining wall material, has shown that it can effectively withstand landslides on the slopes under consideration. The slope safety factor rose dramatically after being reinforced with type X-blocks, reaching 2.73 for both X-block type 1 and X-block type 2. Doi: 10.28991/CEJ-2022-08-03-014 Full Text: PDF

Published: March 2022

The China-Pakistan Economic Corridor (CPEC) is a massive in-progress construction project in Pakistan that connects more than 70 countries via multiple trade channels such as highways, railways, roads, and fiber optics. This project also involves the development of local infrastructure and industrial zones in Pakistan, which demands the discovery of new resources of aggregate to facilitate the construction. Therefore, physical characterization research was carried out on the Kirman hill region (Jurassic limestone), District Kurram, Pakistan, to investigate their suitability for utilization as construction materials using site investigation and laboratory studies. The results outline that all typical engineering parameters are within acceptable limits set by international standards like BS, ASTM, and AASHTO. Bituminous tests revealed that Jurassic limestone is appropriate as an aggregate for asphalt wearing coarse. Likewise, the petrographic study performed shows proper matching with engineering tests. The petrographic analysis of Jurassic limestone showed a minute amount of deleterious content; as a result, it is resistant to Alkali silica reaction (ASR) and Alkali carbonate reaction (ACR) expansions. Based on engineering and petrographic analysis, the Jurassic limestone, Kirman hill region, District Kurram, Pakistan is recommended as a potential aggregate for (i.e., base course, subbase course, cement concrete, and asphalt) and other mega and minor civil construction projects. Doi: 10.28991/CEJ-2022-08-03-02 Full Text: PDF

Se reconoce en la literatura que un camino legítimo para garantizar el crecimiento y desarrollo de la empresa es el intraemprendimiento. En este sentido se identificó la necesidad de una comprensión profunda de las condiciones que generan el fenómeno en entornos considerados hostiles, a fin de determinar factores que fomenten o inhiban tal comportamiento. Para lograr lo anterior, se planteó un método de investigación cualitativo, de diseño no experimental y alcance exploratorio, cuyo diseño de campo consistió en el análisis documental y en la aplicación, transcripción, codificación y análisis de 11 entrevistas realizadas a personas altamente relacionadas al fenómeno intraemprendedor de algunas ciudades del norte, centro y sur del estado de Tamaulipas, México. El método empleado permitió el reconocimiento de factores subyacentes que detonan, potencializan o inhiben el intraemprendimiento, algunos de los cuales, han sido poca o nulamente abordados en investigaciones previas, tales como la influencia de apoyos gubernamentales, cuestiones referentes a la percepción de los altos mandos en materia de seguridad y factores del comportamiento de los mandos inferiores.

Responding to COVID-19: What we learned in 2020
Authors: Reid Mary Anne , Forrest Kirsty
Published: March 2022

Introduction: This article summarises a report published in July 2021 by Medical Deans Australia and New Zealand (Medical Deans), the peak body representing the 23 medical programs in Australia and New Zealand. It explores how medical schools responded to the early impacts of COVID-19 in 2020, and how they might build on some of the changes to achieve fundamental improvements in medical education in Australia and New Zealand.
Methods: The Medical Deans report was based on: Responses to a survey midway through 2020 of its member schools about their experiences during the initial lockdowns; the contributions of presenters at the Medical Deans 2020 Annual Conference; subsequent discussions among communities of practice.
Results: Innovations introduced in response to the pandemic, included greater equity of learning opportunities across geographical locations; health services taking more responsibility for clinical placements; greater emphasis on competencies and less on clinical rotations in specific disciplines; strong collaboration between medical schools, and with providers in the medical training and research pipeline. Challenges include balancing the benefits of online learning with the need for human connection and a chronic lack of clinical training opportunities in community-based care.
Conclusion: While the impact of the pandemic on medical education and training was costly for all involved – both financially and personally – the scale of disruption provided a unique opportunity for step change. To fully realise this potential moving forward, medical schools will need to work in partnership with all those involved: students, health services, prevocational training, specialist colleges, regulators and governments.

Authors: Ho Ming-Jung , Chang Yu-Che , Kanter Steven L.
Published: March 2022

Introduction: The COVID-19 pandemic forced medical schools worldwide to transition online. While there are ample reports about medical education adaptations to this crisis, there are limited studies evaluating the impact.
Methods: This study includes a case study of how Taiwanese medical school deans maintained in-person education during the COVID-19 pandemic. Additionally, it demonstrates how SWOT analyses can help medical educators reflect on adaptations during the COVID-19 pandemic and future crises. This study employed two online surveys and a semi-structured interview regarding curricular adaptations. Eligible participants were deans or associate deans of all medical schools in Taiwan.
Results: Through a SWOT analysis, this study identified Strengths as strong leadership, prior experience with SARS, and ability to promptly adapt curriculum; Weaknesses as lack of faculty confidence in online education, limited numbers of administrative staff, and inability to rapidly add new topics; Opportunities as centralised anti-epidemic policies, inter-institutional collaborations, and educational innovations; and Threats as concerns from parents, patients, and teaching hospitals. It is reported that the quality of education was maintained as students’ evaluations of courses, performances in written exams, clerkship supervisors’ assessments, national OSCE, and national board exams remained comparable to pre-COVID times. Strengths and Opportunities such as strong leadership and centralised anti-epidemic policies can overcome Weaknesses and Threats, such as lack of confidence in online education and familial pressure to suspend hospital-based education.
Conclusion: This study recommends that medical school leaders conduct SWOT analyses as early as possible to plan strategies to continue safe and quality medical education during COVID-19 and future crises.

Published: March 2022

Introduction: The transition from medical student to houseman is well recognised as a stressful period for newly qualified doctors. This stress is likely to be heightened when the transition occurs during a pandemic. We aimed to evaluate the perceived stress levels of housemen as they begin housemanship and explore their sentiments and preparedness in starting work amidst the coronavirus disease 2019 (COVID-19) pandemic.
Methods: Housemen starting work at a tertiary institution in Singapore in May 2020 completed the following: (1) Perceived Stress Scale, (2) open-ended questions on perceived challenges and concerns and (3) questionnaire on preparedness and confidence in starting work. Descriptive statistics were used to analyse quantitative data and modified thematic analysis performed for qualitative data.
Results: Sixty-one housemen participated. Thirty-five (57.4%) reported high perceived stress. The themes for perceived challenges in this transition included coping with constant change, lack of reliable information from authorities, dealing with disappointment, physical fatigue, and loss of autonomy. The themes for concerns in beginning housemanship elicited relate to clinical competence, transitioning into new responsibilities, risk of infection with COVID-19, senior expectations, physical fatigue and training-related concerns. Despite these challenges and concerns, housemen were prepared to begin work during this pandemic.
Conclusion: Housemen transitioning during this pandemic experienced additional stressors and unique challenges pertaining to working in a pandemic. Encouragingly, they remain prepared to start work. Institutions and departments should be mindful of the specific concerns and challenges so that appropriate support can be put in place to support these junior doctors.

The Practice of Hajj Substitution in Indonesia: The Search for Legal Certainty through Usul al-Fiqh Approach
Authors: Nurdin Roswati , Rajab H.
Published: March 2022

This article discusses the issue of legal certainty of the practice of hajj substitution (badal haji) in Indonesia for the prospective pilgrims who have died before the pilgrim season or have suffered from chronic diseases hindering them from performing the planned hajj from the perspective of uṣūl al-fiqh approach. Despite the fact that Hajj substitution has been widely practiced, there are problems with regards to both legal basis and actual practices. From the fiqh point of view, the issue is subject to dissent between the scholars and jurists. As for its actual practice, there is a wide opportunity for abuse from irresponsible parties. Along with this background, in seeking for legal certainty, this article employs bayānī (textual), taʻlīlī (causation), and istiṣlāḥī (public interest) reasoning of uṣūl al-fiqh upon the relevant literature. Through bayānī reasoning, this article concludes that hajj substitution is obliged by some texts of hadith. Taʿlīlī reasoning reveals that the obligation applies only to the people who are at some point had reached the level of istiṭāʿa in their life. Finally, istiṣlāḥī reasoning unveils a number of adverse situations that one should take into consideration when planning for a hajj substitution on behalf of another, such as the issue of trust with the substitute of the hajj. Accordingly, this article argues that hajj substitution is allowed to be performed under the specific provision and trustworthiness.
Friends of the Lake? Ontological Politics and the Megacolector Conflict
Authors: May Timothy
Published: March 2022

There is growing recognition that radical ontological difference underlies Indigenous communities’ opposition to extractivist development within their territories. Scholars writing from a political ontology (PO) framework excitedly posit the possibility of the pluriverse emerging from the ‘ontological openings’ (de la Cadena 2015a) that these struggles are forming in the project of modernity. While such accounts are useful in elucidating how such struggles are more than ‘mere resource conflicts’ (Coombes et al. 2012a), they also risk reifying ontological difference and losing sight of the power asymmetries which shape its pragmatic and strategic articulation. More than just a matter of academic debate, overstating the ontological difference of Indigenous opposition to extractivism is a ‘cosmopolitical risk’ (Cepek 2016) that has the potential to limit Indigenous communities’ particular aspirations for self-determination. As a consequence, this article suggests a way forward can be found in ‘ontologizing political economy’ (Burman 2016) whilst also paying closer attention to the contingent nature of worlding, as well as ontological ambiguities and ‘partial connections’ (de la Cadena 2015a). This article fleshes out these theoretical concerns through drawing upon my ethnographic research about an ongoing ‘resource’ conflict in Guatemala. Over the last few years, the Maya Tz’utujil community of San Pedro la Laguna has been strongly opposing the ‘megacolector’ – a wastewater megaproject being advanced as a solution to Lake Atitlan’s contamination by the environmental NGO ‘Asociación de Amigos del Lago de Atitlán’ (Association of Friends of Lake Atitlán). Through engaging with a range of Pedrano community members, I reflect upon the usefulness of a PO framework for understanding the megacolector conflict’s ontological dimensions and the motivations of San Pedro’s opposition movement.
The Triumph of the Will of Athletes in Infinite Jest
Authors: Redgate James
Published: March 2022

In 1995, in the introduction to Tennis and the Meaning of Life: A Literary Anthology of the Game, Jay Jennings lamented that there were still “no great” tennis novels. Had the collection been published just a year later, a revision would have been in order. David Foster Wallace’s Infinite Jest (1996), the encyclopaedic masterpiece set around the grounds of Enfield Tennis Academy, is a great tennis novel. Yet, when critics discuss Wallace’s work on tennis, the focus is usually on his essays and tends to fall into one of two camps: either emphasizing the bodies of Wallace’s dumb jocks, or the divine inspiration that helps them play so well. Once we recognise that Wallace’s treatment of character was itself always dualistic, we can begin to reconcile these two apparently conflicting points of view. Doing so will shed new light on Wallace’s treatment of tennis as a stress-test of the connection between body and soul, and will raise difficult questions about the fate of a country where that test is so necessary.
Mediation Effect of Insomnia Symptoms on Relation Between Stress and Quality of Life

Objective Among various causes of insomnia, stress is the most common and representative cause. Insomnia is also known to negatively affect the quality of life (QoL). The objective of this study was to explore the effect of stress on QoL and the mediating role of insomnia symptoms in the relationship between stress and QoL.Methods In this study, the mediating effect of insomnia symptoms on the relationship between stress and QoL was analyzed by enrolling 3,714 participants from the Ansung and Ansan cohorts of the Korea Association Resource project from 2001 to 2004. These cohort participants were asked about how much they felt stressed during their everyday life. Insomnia symptoms were evaluated by asking participants whether they had trouble sleeping such as difficulty in falling asleep, disrupted sleep, and early morning awakening due to the lack of a validated questionnaire for this cohort. QoL was evaluated using the World Health Organization QoL Scale Brief Version.Results In total, stress was positively associated with insomnia symptoms, which in turn predicted QoL. The same result could be derived from subgroup analysis according to sex, and it was confirmed that insomnia symptoms acted as a mediating factor more significantly in female than in male.Conclusion In this study, insomnia symptoms were confirmed to act as a significant mediating factor between stress and QoL, suggesting that insomnia symptoms should be actively identified and controlled to alleviate the negative effect of stress on QoL in clinical practice.
Rainwater harvesting for enhancing upland agriculture: Lessons and experiences in selected upland farming communities in Albay Province, Philippines

The upland farming communities in the Philippines are among the vulnerable sectors to climate change impacts. Their agricultural production is generally rainfed, and their farms are in marginal upland areas with steep slopes prone to soil erosion. Water scarcity is a common and perennial problem. To address the need expressed by the smallholder farmers, 11 rainwater harvesting facilities (RWHFs) were established in three upland farming communities in Albay Province, Philippines. The project team facilitated the establishment of RWHFs from two state universities, three local government units, and farming communities. Capacity development and participatory project planning and implementation were the important project approaches. This project generated several lessons. These include the essence of multisectoral collaboration, comprised of local government units, farming communities, and state colleges and universities; the value of collective action of farmers; effectiveness of cross-farm visits and on-site training; tapping locals for project monitoring; integration of sustainable land use management system to sustain RWHFs; and, the importance of resource sharing in carrying out project activities. The project experiences and lessons could be used as a reference by other development programs in replicating this initiative in other upland farming communities in the country.

Introduction: Solid pseudopapillary neoplasms (SPN) and pancreatic neuroendocrine tumors (NET) are rare diseases that are generally incidental findings in imaging tests. SPN is a low-grade tumor with good prognosis that more commonly affects young female patients. Pancreatic NET has a significant variability in outcomes, with low malignant potential in non-progressing tumors that are welldifferentiated. Both tumors may appear very similar in imaging tests and immunohistochemical (IHC) evaluation, which makes the differential diagnosis challenging, especially in small lesions. Case report: The authors present the case of a 34-year-old male with a medical history of a primary mediastinal germ cell tumor. The patient had no symptoms. Follow-up abdominal CT scan evidenced a single, well-delimited nodular lesion in the pancreatic neck, measuring 17mm in diameter. The patient was submitted to an endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNA) and after IHC analysis, there was a diagnostic suspicion of low-grade pancreatic NET. Central pancreatectomy (CP) was performed and complete lesion analysis evidenced a pancreatic SPN. Conclusion: The SPN can mimic low-grade nonfunctioning pancreatic NETs in imaging tests and EUSFNA IHC evaluation.

Introdução: O câncer de mama, excluindo as neoplasias de pele, é o tumor maligno mais comum na população feminina. O diagnóstico de metástase gastrointestinal secundária ao câncer de mama é extremamente raro. Apesar da maior prevalência do subtipo ductal invasivo, a metástase gastrointestinal ocorre com maior frequência em pacientes com carcinoma lobular invasivo. Relato do caso: Nesse relato, é reportado o caso de uma mulher de 72 anos, que iniciou com sintomas dispépticos, náuseas e vômitos 4 meses após o diagnóstico de carcinoma ductal invasivo de mama. Após investigação, evidência de metástase gástrica com invasão da raiz do mesentério, sem indicação de ressecção cirúrgica, sendo encaminhada para tratamento hormonal e quimioterápico. Conclusão: Nesses casos, apesar da raridade de metástases do câncer de mama para o trato gastrointestinal, é importante realizar o diagnóstico correto, a fim de avaliar o melhor tratamento para cada caso.
