Authors: Kyalo Juliana
Published: November 2023

Purpose: The purpose of this study was to examine the role of information technology in strategy implementation within Kenya's Government Tourism Agencies

Materials and Methods: The study adopted a positivist research philosophy and utilized explanatory and descriptive research designs. The target population for the study consisted of the tourism industry, including the ministry of tourism, which oversees the operations of tourism agencies. This resulted in a total of 10 areas of study. To determine the sample size, a total of 327 participants were selected using a specific formula. The study collected primary data through the use of questionnaires and interview guides, allowing for the collection of both qualitative and quantitative data. Quantitative data was analyzed using scientific methods using the statistical package for social sciences (SPSS version 22), while qualitative data was analyzed thematically. The analysis began with descriptive statistics, which examined the demographic factors of the respondents through the use of frequencies and charts. Additionally, inferential statistics such as correlation and multiple linear regression analysis were employed to test the relationships among the variables as hypothesized in the study.

Findings: Adopting information technology in functions and organizational decision making processes was also found to have significant effect on the process of strategy implementation. In a nutshell, the organizational leadership, organizational structure, organizational culture, resource allocation and extent of IT integration in an organization influence the way strategies are implemented in organizations.

Implications to Theory, Practice and Policy: Theoretically, it enriches the stakeholder theory by elucidating how different stakeholders, influenced by information technology, impact strategy implementation in the public sector, particularly in the context of a developing country. This study adds a new dimension to force field analysis by integrating IT aspects, showing how technological forces act as either drivers or barriers in strategic implementation. Practically, it provides valuable insights for managers and policymakers in Kenyan tourism agencies, highlighting how IT can be leveraged to align stakeholder interests and overcome resistance in strategy execution. For policy, it underscores the critical role of IT in modern governance and strategic management, suggesting policy reforms for enhancing IT infrastructure and capabilities in government agencies.

Published: November 2023

A school is a sub-organization of the community, and both are important for developing the other; a school alone cannot achieve success without the cooperation of the community. Hence, the school needs to obtain the cooperation of the community for the growth of the students’ education. The objectives of this study were to measure the present status of the community contribution to improving the academic achievement of students, evaluate actions taken by schools to increase community contribution, analyze the relationship between actions taken by schools and community contribution, and analyze the impact of the community contribution on the academic achievement of students. This study was conducted in a quantitative domain with a descriptive survey design. Questionnaires and documents were used to gather data. Ten principals, ten deputy principals, forty teachers, twenty parents, and twenty past pupils were selected as samples using purposive sampling techniques. A descriptive analysis method was used to analyze the data. The following results have been obtained: the present status of community contribution was at a low level, the actions taken by the school to increase community contribution were high, and the actions taken by schools had a moderately positive impact on community contribution. Also, the community contribution had a moderately positive impact on the academic achievement of students. As a result, there will be a positive impact on the academic achievement of students if the schools have an effective relationship with their community.

Published: November 2023

Credit card churn, where customers close their credit card accounts, is a major problem for banks and other financial institutions. Being able to accurately predict churn can allow companies to take proactive steps to retain valuable customers. In this review, we examine how machine learning and deep learning techniques can be applied to forecast credit card churn. We first provide background on credit card churn and explain why it is an important problem. Next, we discuss common machine learning algorithms that have been used for churn forecasting, including logistic regression, random forests, and gradient boosted trees. We then explain how deep learning methods like neural networks and sequence models can capture more complex patterns from customer data. The available input features for churn models are also reviewed in detail. We compare the performance of different modeling techniques based on past research. Finally, we discuss open challenges and future directions for predictive churn modeling using machine learning and deep learning. Our review synthesizes key research in this domain and highlights opportunities for advancing the state-of-the-art. More robust churn forecasting can enable companies to take targeted action to improve customer retention.

Concrete is the most widely used construction material in the world. It is now possible to construct structures out of concrete because this durable compound that consists of water, aggregate, and Portland cement not only gives us many scopes of design but also has a very high compressive strength at a low cost. This paper deals with alternative materials for the most common construction material, cement-based concrete and polymer concrete (PC), containing waste tin fibres. The study covers the fabrication of polymer concrete and the execution of three tests: compressive strength, flexural tensile, and splitting tensile. Tests were conducted to determine the mechanical properties of the PC, and the results were analysed and evaluated on several PC specimens with different ratios of waste tin fibre. The results showed that using waste tin as fibre reinforcement in PC would substantially enhance the overall mechanical performance. Specifically, the optimum amount of waste tin as reinforcement in PC was 0.16% for compressive and splitting tensile strengths, while 0.20% was the optimum fibre loading for the flexural tensile strength. In this case, a positive outcome was found at a constant resin-to-filler ratio of 40:60 by volume and a matrix-to-aggregate ratio of 1:1.35 by weight.

On the 22nd of December 2018 tsunami waves generated by the flank collapse of the Anak Krakatau volcano in Indonesia flooded the shorelines of the nearby Sumatra and Java islands. The authors conducted a field survey of the Krakatau group of islands to clarify the volume of the collapsed flank and the run-up of the tsunami around the island themselves. To aid with the simulation of this complex tsunami and document the current situation of the islands, bathymetric surveys, aerial drone and panoramic video mapping were also carried out. The results show that while much of the source directionality was towards the SE of Anak Krakatau, significant wave run-ups were also measured towards the NW, indicating that further numerical modelling is needed to fully explain this event.
Numerical investigations of ship forces during lockage
Authors: Thorenz Carsten , Schulze Lydia
Published: November 2023

The evaluation of ship forces for planned or existing navigation lock systems is essential for a sound design in terms of safety, cost and speed. It is a complex task that requires knowledge in physical understanding and modelling of the ongoing hydraulic processes during the lock filling. In this case study, focus is put on the ability to analyse the magnitude of the ship forces with a three-dimensional computational fluid dynamics (CFD) model based on the OpenFOAM software package. The inhouse state-of-the-art of the ship force evaluation during levelling with the means of three-dimensional numerical modelling is presented. The results are compared to physical model tests in scale 1:25 and discussed. The outcome showed a very good agreement in terms of flow rates and longitudinal ship forces. The results for the transversal ship forces are promising because the system behaviour is reproduced but the accuracy of the peak values is still to be enhanced. An analysis shows several possible sources for these discrepancies.
Field measurements of very oblique wave run-up and overtopping with laser scanners

Published: November 2023

This paper presents the first field measurements with an innovative laser scanner system, during an actual severe winter storm with very oblique wave attack. The goal of this paper is to validate this innovative system for measuring wave run-up and wave overtopping parameters during storms with very oblique wave attack. The paper describes the analysis of the run-up and overtopping data obtained during storm Ciara (10 - 12 February 2020) and validates the results with data from overtopping tanks and video recordings. Storm Ciara was a highly unique and complex storm, with offshore-directed wind and alongshore-directed waves at the dike. This posed large challenges for measuring the front velocities. The wave run-up heights and the overtopping discharges could be measured accurately with the laser scanners. Reasonable results were achieved for the run-up depths. This has led to several new insights into the probability distribution of oblique wave run-up and the run-up depths of up-rushing oblique waves. Larger deviations were found for the 2D front velocities and wave angle of incidence, which could not be determined as well for storm Ciara. This arose from the highly complex conditions during Ciara with very oblique wave attack. The mobile system is now ready to be used at several different locations in the measurement campaign in this area over the coming years.
Rock Armour Slope Stability under Wave Attack; the Van der Meer Formula revisited
Authors: VAN DER MEER JENTSJE
Published: November 2023

The Van der Meer formula for rock slope stability under wave attack has been in use now in research and design for more than thirty years. This paper takes the original formula as a basis and then explores into a larger field of application, as investigated by various authors, or includes improved insights in parameters to be used. The spectral period has become the leading wave period over the mean or peak period in the field of wave overtopping. First the Van der Meer formula has been rewritten to include this spectral wave period, based on original data.

A guideline how to compare new research in extending application areas has been developed, including how to come to a modification of the formula. First the essence of the Van der Meer formula is given, such as a gradually developing damage curve according to a power function and the relationship between damage development and storm duration. Each new research should be validated for these relationships before a direct comparison is possible. Such comparison can be done along graphs of damage versus the breaker parameter (including wave period and slope angle), including the original data of the Van der Meer formula.

Possible modifications to the formula are best described if using multiplication coefficients for plunging and surging waves that directly show the influence on the original formula by the deviation from the value 1.0. Two significant investigations have then been re-analysed along the developed guidelines, one on rock shape and one on rock placing.

The research on rock shape was performed with a significant thinner armour layer, so it actually included two effects: rock shape and a thinner armour layer. The two effects have been divided and can be described by adjusted multiplication coefficients.

Individually placed rock with three points of contact, or placed with a dense packing, increase stability significantly and may always be seen as a good measure. The damage curve, however, is not gradually developing, but shows a kind of brittle failure. Direct comparison with the Van der Meer formula is not possible then. A brittle failure needs a safety coefficient, showing for design similar stone sizes as with the formula.
Formulation of a Surf-Similarity Parameter to Predict Tsunami Characteristics at the Coast

Published: November 2023

To calculate tsunami forces on coastal structures it is of great importance to determine the shape of the tsunami front reaching the coast. Based on literature reviews, analytical reasoning, video footage, and numerical modelling it is concluded that both the continental shelf slope and the bay geometry have a significant influence on the transformation of a tsunami wave near the coastline. After conducting 1D and 2DH wave simulations, a distinction is made between three types of tsunami waves; a non-breaking front (surging), a breaking front and an undular bore breaking front. Tsunami waves transform into these three wave types over a steep continental shelf, an intermediate sloped continental shelf, and a gentle sloped continental shelf, respectively. A new tsunami surf-similarity parameter is proposed to quantitatively predict the type of wave at the coastline, which was validated based on observations during the 2011 Tohoku Earthquake and Tsunami.
Investigating Wave Transmission through Curtain Wall Breakwaters under Variable Conditions

Published: November 2023

Coastal erosion has become a pressing problem all over the world, especially in areas where the hinterland is only slightly elevated over the sea level. The ongoing progression reveals the urging need for engineered coastal protection measures like breakwaters. Amongst others, curtain wall breakwater types (CWB) have proven their potential to dissipate the wave energy in multiple studies. Their application is often considered in situations where only a partial protection of the coast is needed (e.g. to maintain a hydraulic connectivity or enable sediment transport for land reclamation). Due to their slender design, they are assumed to offer an economical alternative in comparison to massive breakwater constructions, while their pillar-based foundation shows advantages for applications under soft soil conditions. Within the development process of a detached breakwater to face coastal erosion in the Mekong Delta, different types of CWB configurations have been investigated under regular wave conditions. Several characteristics of CWB structures such as the inclination and thickness of the wall, the height of the structures, the rate of submergence and emergence were examined for different water depths and wave parameters. The wave-structure interaction was analyzed using FLOW3D software, which is capable of simulating wave transformation. It showed a high agreement in comparison with own experimental investigations and the wave theory. The results showed a continuous reduction of the wave transmission coefficient with increasing inclination from 90° to 135°, whilst the orientation of the inclination (e.g. 60° vs 120°) only showed a minor effect regarding the wave reduction. All CWB arrangements showed increasing performance with decreasing wave periods. Besides, the wave transmission was mainly impacted by the level of submergence together with the amount of supporting piers and the thickness of the structures. Water depth changes due to tidal influence revealed an increase in wave transmission coefficient once the wave started to overtop the structure.

Os saberes para a docência em Matemática: o que dizem professores formadores?
Authors: Scopel Boff Daiane , Bonato Gabriela Costa
Published: November 2023

Esta pesquisa investiga os saberes docentes descritos e mobilizados por professores formadores que desenvolvem a docência em curso de Licenciatura em Matemática. A questão de pesquisa, explicitada por: Que saberes são mobilizados nas docências desenvolvidas em cursos de Licenciatura em Matemática e de que maneira os professores reconhecem esses saberes como necessários à docência em Matemática?, foi construída no tensionamento das discursividades do presente sobre a identidade profissional e os saberes necessários à docência em Matemática. O material analítico, produzido a partir de entrevistas semiestruturadas realizadas com doze professores de diferentes áreas do conhecimento, foi descrito e analisado a partir das pesquisas de Tardif (2014), Pimenta (2012) e Gauthier et al. (2013). Com inspiração analítica na análise de discurso (Bardin, 1977), são construídos dois grupos de sentido a partir da materialidade, ambos forjados nas falas dos professores formadores: o primeiro, mostra que a docência se constitui em movimento, sendo permeada por múltiplos saberes e, o segundo, apresenta a sala de aula, considerada como o locus da experiência docente, como um espaço propício para a construção de diferentes aprendizagens. Assim, no movimento analítico realizado, os saberes disciplinares, relativos ao conhecimento matemático, são considerados essenciais; entretanto, outros saberes também são potencializados, em especial, os construídos na experiência, no exercício da profissão docente, o que faz da sala de aula um laboratório de aprendizagem.

Published: November 2023

O Estágio Curricular Supervisionado é considerado uma fase da formação de grande importância para aproximação do estagiário de sua futura prática docente e segue sendo abordado em diversas pesquisas. Entretanto, detectamos que a atividade supervisiva não vem sendo explorada nestas pesquisas e carece de clareza em suas atribuições (Maciel, 2015; Benites, Sarti e Neto, 2015). Com o intuito de compreender como se compõe e estabelece esta atividade, realizamos entrevistas semiestruturadas (Boni, Quaresma, 2005) com quatro professores de Matemática da Educação Básica, experientes na supervisão de estagiários em suas salas de aula. Realizamos uma análise comparativa entre estes depoimentos e resumidamente o que encontramos a) a compreensão dos supervisores de sua atividade como aproximação dos estagiários da prática docente, mas falta clareza do que consiste a atividade supervisiva; b) ausência de diálogo entre as instituições universidade e escola campo; c) falta de incentivo e condições para o exercício de tal atividade.

Authors: Machado Vanessa Noguez , Rover Suliani
Published: November 2023

Este artigo tem como objetivo analisar a influência do enforcement dos países no conservadorismo contábil das empresas de capital aberto dos países membros do G20. Para tanto, foram analisadas 33.228 empresas não financeiras de capital aberto no período de 2016 a 2020, sendo classificadas de acordo com seu desenvolvimento econômico nos países analisados (Desenvolvidos e Emergentes), bem como o regime jurídico adotado por essas economias (Common Law e Civil Law). Para análise, foi realizada regressão de dados em painel, utilizando os modelos de conservadorismo condicional propostos por Basu (1997) e Ball e Shivakumar (2006). A partir da análise comparativa dos resultados, foi possível evidenciar que países desenvolvidos tendem a apresentar maior conservadorismo em seus números contábeis, assim como países com sistema legal de Common Law, constatando que um enforcement mais rigoroso tende a fazer com que as empresas apresentem maior conservadorismo em seus resultados.

Private and Secure Post-quantum Verifiable Random Function with NIZK Proof and Ring-LWE Encryption in Blockchain
Authors: Kim Bong Gon , Wong Dennis , Yang Yoon Seok
Published: November 2023

We present a secure and private blockchain-based Verifiable Random Function (VRF) scheme addressing some limitations of classical VRF constructions. Given the imminent quantum computing adversarial scenario, conventional cryptographic methods face vulnerabilities. To enhance our VRF’s secure randomness, we adopt post-quantum RingLWE encryption for synthesizing pseudo-random sequences. Considering computational costs and resultant on-chain gas costs, we suggest a bifurcated architecture for VRF design, optimizing interactions between on-chain and off-chain. Our approach employs a secure ring signature supported by NIZK proof and a delegated key generation method, inspired by the Chaum-Pedersen equality proof and the Fiat-Shamir Heuristic. Our VRF scheme integrates multi-party computation (MPC) with blockchain-based decentralized identifiers (DID), ensuring both security and randomness. We elucidate the security and privacy aspects of our VRF scheme, analyzing temporal and spatial complexities. We also approximate the entropy of the VRF scheme and detail its implementation in a Solidity contract. Also, we delineate a method for validating the VRF’s proof, matching for the contexts requiring both randomness and verification. Conclusively, using the NIST SP800-22 of the statistical randomness test suite, our results exhibit a 98.86% pass rate over 11 test cases, with an average 𝑝-value of 0.5459 from 176 total tests.

The use of thermal imaging and computer vision has seen a sharp increase in recent years. This paper presents the current state of the art concerning these fields. Thus, a review of research articles studying the combination of these technologies for pattern recognition is established. After presenting an overview of the topic, a bibliometric analysis is selected based on 1160 articles extracted from the Scopus database, which allows assessing the temporal evolution of the publications and the study of their most relevant sources, authors, keywords, trend topics, and publishing countries. Besides, a particular focus is given to the issue of defect detection using thermal imaging and computer vision. The related articles are analyzed and classified into their primary domains. The results confirm that combining thermal imaging with computer vision techniques has become commonly used in several fields. However, the defects detection case studies using these technologies are focused on a few application fields. Thus, more contributions are required regarding this specific issue in more innovative applications. This review will help to guide future research contributions within all fields where creative uses of infrared thermal imaging and computer vision can be developed to recognize different patterns and issues.

Günümüzde tanı ve girişimsel tedavilerdeki büyük ilerlemelere rağmen kalp damar hastalıkları mortalite yanında önemli iş gücü ve ekonomik kayıplara da neden olmaktadır. Bu olumsuzlukların önüne geçebilmek ve/veya en aza indirebilmek için yaşam tarzı değişiklikleri ile uygun beslenme ve düzenli egzersiz programları yaygın şekilde önerilmelidir. Hastaya özel yapılandırılmış fiziksel aktivite programları ile klinik durumun stabilize edilmesi, semptomatik kontrolün sağlanması, fonksiyonel durumun iyileştirilmesi, aerobik egzersiz kapasitesinin geliştirilmesi, kanıta dayalı kardiyovasküler tedavinin optimizasyonu, mesleki ve rekreasyonel aktivitelere katılımın artırılması, psikososyal iyilik halinin geliştirilmesi, engellilik halinin önlenmesi, iş ortamına geri dönüşün sağlanması ve mortalite riskini azaltılması sağlanabilmektedir. “Spor Kardiyolojisi ve Kalp Damar Hastalıkları” kitabımızdan ümit edilen, kalp damar hastalığına sahip her bireyin kendisine uygun fiziksel aktivite programlarını benimseyerek kendisini günlük yaşam aktivitelerinden uzak bırakmamasıdır.
Kardiyovasküler Sistem ve Egzersiz
Authors: Fuat Sönmez Osman
Published: November 2023

Kardiyovasküler sistem sistemik ve pulmoner dolaşımdaki kanın kesintisiz olarak damar sistemi içinde akmasını sağlar. Bu sayede vücut sistemlerinin ihtiyaç duyduğu oksijen ve besin maddeleri sağlanırken dokular tarafından üretilen metabolik atıklar ortamdan uzaklaştırılır. Kardiyovasküler sistem fonksiyonları, vücut üzerinde stres oluşturan egzersiz gibi faktörlere bağlı olarak değişiklikler gösterir. Egzersiz sırasında vücudun artan oksijen ihtiyacı ve metabolik artıkların birikmesi gibi faktörlere bağlı olarak kardiyovasküler sistem fonksiyonları hızlanır. Kardiyovasküler fonksiyonlarında görülen bu değişikliğin seviyesi, egzersize katılan kas gruplarının kütlesi, egzersizin yoğunluğu, süresi, egzersizin yapıldığı ortam koşulları gibi çeşitli faktörlere bağlıdır. Egzersiz sırasında kardiyovasküler sistemde görülen değişikliklerin bir kısmı hemen egzersiz sırasında ortaya çıkarken, bir kısmı ise uzun dönemde düzenli egzersiz yapılması sonucu ortaya çıkar.
Sporcu Kalbi
Authors: Altan Mehmet
Published: November 2023

Düzenli fiziksel egzersizlerin bir sonucu olarak sporcuların kalplerinde gözlenen işlevsel, yapısal ve elektrofizyolojik adaptasyonlar sporcu kalbi olarak tanımlanır. Egzersize yanıt olarak gözlenen bu adaptasyonlar fizyolojik özelliktedir ve kardiyak fonksiyonların gelişimine katkıda bulunarak sonuç olarak egzersiz performansını artırır. Bununla birlikte, bu fizyolojik değişiklikler bazen patolojik değişikliklerle karıştırılabilir ve bu durumun ayırt edilmesi, sporcu sağlığı ve kariyeri açısından büyük önem taşır. Düzenli fiziksel egzersizin sporcu kalplerinde meydana getirdiği adaptasyonlar, neredeyse her zaman sportif faaliyetlere ara verilmesiyle gerileme gösterir.
Kalp Kapak Hastalıkları ve Spor Kardiyolojisi

Kalp kapak hastalıkları, egzersiz yapmak isteyen bireyler için önemli bir endişe kaynağıdır. Egzersiz, kalp kapak hastalıklarının seyrini nasıl etkiler ve bu hastaların spor katılımı nasıl olmalıdır soruları, spor kardiyolojisinde araştırma ve kılavuzlar yoluyla ele alınmıştır. Herhangi bir düzeyde egzersiz yapan bireylerin %1’den fazlasında kalp kapak hastalığı tespit edilmiştir ve egzersizin artan atım hacmi, güçlü miyokard kontraksiyonu ve kronotropi gibi etkileri kapak disfonksiyonunu hızlandırabilir. Ancak, bu konudaki kanıtlar sınırlıdır. Kalp kapak hastalığı olan bireylerin spor katılımı değerlendirilirken semptomlar, fonksiyonel kapasite, kapak hastalığının doğası ve kardiyak yapının etkileri göz önünde bulundurulmalıdır. Tüm bireylerin öykü, fizik muayene, elektrokardiyografi, ekokardiyografi ve egzersiz stres testi ile değerlendirilmesi önerilir. Aort kapak darlığına sahip sporcularda ciddiyet derecesi genel popülasyonla aynıdır. Hafif düzeyde aort kapak darlığı olan bireyler, tüm rekreasyonel ve yarışmalı sporlara katılabilirler. Orta düzeyde aort kapak darlığı olan kişilerin uygun şartlar altında düşük yoğunluklu rekreasyonel sporlara katılımları düşünülebilir. Semptomatik ciddi aort kapak darlığı olan bireylerin spor katılımı önerilmez, ancak düşük düzeyde egzersiz düşünülebilir. Mitral ve triküspit kapak yetersizliği olan bireylerin spor katılımı da bireyselleştirilmelidir. Hafif yetersizliği olanlar rekreasyonel ve yarışmalı sporlara katılabilir. Ciddi yetersizlikte, semptomlar ve diğer faktörler göz önünde bulundurularak spor katılımı önerilmez. Kalp kapak hastalıklarıyla ilgili spor kardiyolojisi önerileri, bireyselleştirilmiş yaklaşımlar gerektirir. Egzersizin kalp kapak hastalıkları üzerindeki etkileri, hastanın durumu, semptomları ve test sonuçlarına bağlı olarak değerlendirilmelidir. Bu öneriler, hastaların sağlıklı ve güvenli bir şekilde spor yapmasını sağlamak için klinik uzmanlık ve multidisipliner bir yaklaşımın gerekliliğini vurgular.”

Kardiyomiyopatiler, genç bireylerde ani kardiyak ölüm ve ani kardiyak arest riskini artırabilen ciddi kalp hastalıklarıdır. Bu hastalıklarda egzersizin potansiyel riskleri ve faydaları dikkate alınarak egzersiz önerileri belirlemek önemlidir. Bu metin, farklı kardiyomiyopati tipleri (hipertrofik, aritmojenik, sol ventrikül nonkompaksiyon ve dilate kardiyomiyopati) ile ilgili spor yapma konusundaki önerileri ve riskleri ele almaktadır. Özellikle hipertrofik kardiyomiyopati, ani kardiyak ölüm riskini artırabileceği için yarışmalı sporlardan kaçınılması önerilirken, bazı bireylerde daha esnek bir yaklaşım düşünülebilir. Aritmojenik kardiyomiyopati durumunda da yüksek yoğunluklu egzersizin ani kardiyak ölüm riskini artırabileceği göz önünde bulundurulmalıdır. Sol ventrikül nonkompaksiyon kardiyomiyopatisi ve dilate kardiyomiyopati durumlarında ise egzersiz önerileri daha farklılık gösterebilmektedir. Sol ventrikül nonkompaksiyon kardiyomiyopatili bireylerde, sol ventrikül sistolik disfonksiyon veya ani kardiyak ölüm riski varsa egzersiz kısıtlanmalıdır. Dilate kardiyomiyopatide ise egzersizin kardiyak fonksiyon üzerindeki etkisi dikkate alınarak, uygun bireyler için egzersiz programları düşünülmelidir. Metinde belirtilen her bir kardiyomiyopati türü için önerilen yaklaşımlar ve takip süreçleri, hastaların bireysel durumlarına göre uyarlanmalıdır. Her hastanın risk faktörleri, semptomları ve klinik özellikleri göz önünde bulundurularak kararlar alınmalıdır. Bu tür kararlar, kardiyoloji uzmanları tarafından verilmelidir ve hasta güvenliği en üst düzeyde tutulmalıdır

Aterosklerozdan sonra aortada en sık görülen patoloji aortanın anevrizmasıdır. Anevrizmalar artmış kardiyovasküler olay sıklığı ile ilişkili olabildiği gibi aort anevrizması olan hastalarda da eşlik eden kardiyovasküler risk faktörleri ve sekonder olay sıklıkları yüksek olabilmektedir. Torasik aort anevrizması klinik spektrumu asemptomatikten aorta diseksiyonu ve hayatı tehdit eden durumlara kadar değişkenlik gösterebilmektedir. Bu hastalarda fiziksel egzersiz ve tedavi rejimi konusunda komorbid hastalıklar (bağ dokusu hastalıkları gibi), yapısal kalp problemleri, aile öyküsü, geçirilmiş cerrahi öyküsü ve sistemik hastalıklar gibi eşlik eden durumların detaylıca değerlendirilmesi sonrasında hastaya özgü olarak karar verilmelidir.
