Authors: Anwer Izza , Yousuf Irfan
Published: June 2024

Autonomous vehicles (AVs) are going through many phases of trail and testing in advanced countries. Though the technological aspects are progressing, yet the social aspects of AVs related to users from developing countries are under-studied. Therefore, this study aimed to investigate the grounds for prospects of AVs in evolving countries. From users’ perspective, technical, regulatory, and social challenges were addressed for smoother inclusion of AVs in mainstream traffic and markets. The research methodology involved the development of a questionnaire, which was piloted and was ethically approved. 600 subjects from metropolitan city of evolving country were recruited through random sampling technique. The collected data was analyzed through multiple methods including correlation and descriptive analysis following multiple linear regression techniques. A few findings on the awareness were that 52.5 % respondents had minor understanding of AVs whilst 47.5% were not aware of AVs at all. 25.6 % respondents were attracted to the fact that AVs have less human engagement factor, 25% were aware and hopeful that AVs are support for those who cannot drive due to physical disabilities, physical mobility constraints, 24% were aware of its self-parking features, 24% considered AVs a symbol of status for elite members of society. Regarding barriers towards AVs were also evaluated that presents the main reasons for AVs not yet being thought about or implemented. Results showed that 26% respondents were concerned about the poor infrastructure to support inclusion of AVs, 29.7% were about higher capital cost, 25% were about cyber security issues, 24% were about reduction in drivers' employment, and 27% were about the absence of legislative framework and pre-hand measures to adopt AVs. Based on the detailed study and its findings, the study shows an in-depth picture of the understanding and concerns of the people which was required to understand. The study recommended that the policymakers and industry stakeholders should focus on increasing awareness about the benefits of AVs whilst addressing concerns about cost and infrastructure. It is also required to design comprehensive frameworks regarding complex issues related to legislations, transport system’s existence and upgradation requirements, transport policy inclusive of AVs and promotion of incentives for early adopters. The study is useful for academicians, researchers, engineers, managers, and policy makers of evolving countries.
Improving the Usability of Intelligent Interface Designs
Authors: Drzyzga Gilbert
Published: June 2024

Rapid advances in artificial intelligence (AI) have led to its widespread integration into various aspects of daily life. To create user-centred experiences, it is critical that AI methodologies incorporate usability principles to ensure effective, efficient and satisfying interactions for users. However, challenges arise from the complexity of real-world scenarios and the limitations of established design practices, requiring careful evaluation during system development. This study aims to investigate potential evaluation criteria for the usability assessment of AI-based software systems. The methodology involves synthesising findings from relevant research, defining characteristics of derived principles, condensing information into guidelines, and validating their relevance and structure. By synthesising these efforts, a set of initial guidelines is presented to improve the understanding of how to enhance usability in AI-integrated systems. The proposed considerations aim to establish a more human-centred relationship with AI systems by personalising outcomes while respecting privacy and configuration preferences, with the goal of improving usability and natural interaction between humans and AI.

Published: June 2024

The term UX is usually applied in the software field, but it is also used in the hardware product, space and service at present. Apart from the relatively mature UX evaluation methods in the automotive field, the construction of the UX evaluation system in the smart home appliance field is not perfect enough, and there is no exclusive, flexible, and universal evaluation system.One is that smart home appliances are different from traditional products, such as beds and office chairs, and do not require much brain thinking. Smart home appliances still have interfaces to interact with, but they are different from software products, such as mobile phones and computers, which require long-term interaction; Secondly, different household appliances also have their own characteristics, such as washing machines placing more emphasis on interface interaction, refrigerators placing more emphasis on space capacity, and water heaters placing more emphasis on installation; Thirdly, the usage tasks of existing household appliances are constantly changing according to lifestyle trends, and the emergence of new scenarios leads to changes in the task of evaluating smart household appliances. In addition, many evaluation systems have not been effective in improving the R&D process of household appliance in practice. Due to a lack of understanding of the product development process, the R&D design is unable to address the identified issues and truly assist in improving the product experience.In these cases, an evaluation system and application process mechanism for smart household appliances were built. This paper mainly studies four directions: (1) Combining industry analysis and home appliance attributes, define exclusive UX index specifically for home appliances. (2) Expanding UX index into a dynamic evaluation system, which can be reflected in: ① being applicable to different categories of household appliances, assigning index weights based on user, R&D personnel, and market feedback; ② It can be applied to users with different physical states, such as the elderly and ordinary people, to adjust the difficulty of passing the index; ③ It can be applied in different scenarios and tasks, analyzing lifestyle trends and market feedback, predicting the occurrence of new usage scenarios and tasks, and adjusting evaluation system testing tasks. (3) Integrate the UX evaluation system into the development process of new products, form a complete design and testing process, and help products achieve experience optimization continuously. (4) Based on three successful cases, point out the feasibility of the UX evaluation system for improving the home appliance experience and its positive impact on the market.

Authors: Lu Lu , Chen Chien-Hsiung
Published: June 2024

With the popularity of smart home central control system, the visual design of their user interfaces has become increasingly important. However, the current user experience for smart home central control system user interface design is still lacking. The specific variables of this study are interface layout (i.e., symmetry and asymmetry) and gender (i.e., male and female) of the smart home center control. A total of 40 participants were recruited to participate in the experiment via convenience sampling methods. The results of this study are as follows: (1) The performance of symmetry layout was faster than asymmetry layout. (2) The symmetric layout was more flexible than the asymmetry layout. (3) There existed a significant difference in the task performance of different genders when operating the smart home center control system. Females had better performance than males. (4) In the symmetry layout, males felt that operating this smart home central control system would increase the amount of operations more than females, while the opposite was true in the asymmetry layout. In summary, there existed gender differences in the operation of smart home user interfaces, and they were affected by the user preferences of the interface layout.
Challenges and Opportunities of Low-Code Figma and Modul-F for Use within the Public Sector
Authors: Vanhauer Marleen , Raimer Stephan
Published: June 2024

Low-code/no-code applications becoming more and more popular would especially within the public sector foster faster digitalization of public services. Working with these applications requires no programming skills and therefore, professionals within their domain can easily implement digital prototypes independent of designers and software developers. Respectively, public administrative employees and executives often have a deep understanding of the actual digital public services to be implemented. Low-code development tools have been evaluated within the healthcare sector (Ness et al., 2019), educational sector (Khosrojerdi et al., 2021), whereas Gottschick et al. (2023) applied a software development approach using low-code/no-code for implementation of a public sector cloud service. Lethbridge (2021) stated a need to first provide proper low-code platforms, to have an impact on faster development of digital services. This led us to the question: Which low-code prototyping tools exist and what their opportunities and challenges are when used by public sector employees? By expert evaluation (Harley, 2019), we compared Figma (Figma, 2016) and the Figma-Low-Code plugin (Figma Community, 2020) with the customized low-code platform Modul-F (Senatskanzlei Hamburg, 2023) for the public sector. We found an advanced maturity in structure, layout and functions of both low-code platforms. According to Nielsen’s (2023) usability quality criteria, learnability of Modul-F was fast (high), and learnability of Figma with Low-Code plugin was rated neutral (medium). The efficiency of the Modul-F Editor was high, it was low for Figma with the low-code plugin. However, memorability was low for both platforms. Running the Figma-Low-Code plugin did require programming skills. Building a prototype with the Modul-F Editor did not allow to design individual user flows. In the future, usability studies should be conducted to assess flaws and satisfaction during actual use by public administrative employees, executives, and designers having no programming skills. Moreover, we anticipate that a nation-wide public service design system with component library, e.g. KERN UX-Standard (Senatskanzlei Hamburg, 2024), would fully leverage the potential of any low-code/no-code platform. To conclude, using low-code/no-code platforms requires interdisciplinary teams of administrative staff and designers working together on digital concepts on a professional daily basis.
The Influence of Parent-child Toys and Time of Playing Together on Children’s Problem-Solving Skills in the Early Post-COVID Years
Authors: Yeh Tien-ling
Published: June 2024

The COVID-19 pandemic has significantly impacted family lifestyles, children's capabilities, and parent-child interactions. This study aimed to explore the influences of parent-child interactions with toys and playing time on children’s problem-solving abilities in post-COVID-19. The research process included two phases: (1) Literature Review: The relationship among playtime, toy types, and children’s capability to solve problems.; and (2) Questionnaire Analyses. The questionnaire focuses on the influences of different types of parent-child toys and the time of playing together for age 2-6 kids on problem-solving skills. Choosing 32 questions from Social Problem-Solving Questionnaire (SPSQ) and Problem-Solving Style Questionnaire (PSSQ), preschool education specialists designed this questionnaire. Questionnaires were distributed in December 2023, and 30 of them were collected. The results are as follows. (1) Learning toys with numbers and symbols that aid in reading can help develop children’s logical thinking, thereby enhancing problem-solving skills. When parents and children engage in studying picture or illustration books together, it nurtures children's language capabilities and fosters interest in learning. Furthermore, sensory-motor playthings have a significant impact on the language development of children.; and (2) Children from families with accompanying playtime during 17:00-18:00 (before school time) or 21:00-22:00 (before/during bedtime) showed good analytical problem-solving capabilities. When faced with a complex problem, these children could identify the most crucial factor and, if they encountered a bottleneck, they would review the problem's context and related conditions to devise alternative solutions.
In-depth analysis based on the phenomenon of pedestrians entering the scene when tourists take photos: Designing interactive reminder devices
Authors: Xie Jiaci , Li Menghan
Published: June 2024

This study aims to observe and analyze the behaviour and motivation of pedestrians who accidentally enter the camera frame when tourists are taking photos in the scenic area. Meanwhile, to enhance the photographic experience of tourists, a friendly interactive device is designed to remind pedestrians to avoid the photo-taking area. User interviews and experimental designs are used to analyze the behavioural characteristics of tourists and pedestrians during photo-taking. It is found that both tourists who are interrupted from taking photos and choose to wait silently and pedestrians who interrupt tourists from taking photos exhibit relatively obvious characteristics. Also, the experiments measured that the easiest distance to be interrupted is 2.5-3m from the photographer to the photographed person, and the easiest form of interaction to attract pedestrians' attention is ground projection and sound interaction. To solve the problem of being interrupted while taking photos, this study utilizes machine learning technology to successfully identify tourists' photo-taking actions and combines it with Arduino, Processing, madmapper to initially implement the desired interactive device design to remind pedestrians to avoid the camera frame, thereby increasing tourists' photographic experience and overall scenic area visit comfort.
An Inclusive design methodology for smart home products good for market performance

Published: June 2024

In the background of the rapid development of technology and intelligence, intelligent technology has brought more novel and convenient experiences to most users when using home appliances. It is because young users have become accustomed to the smart products, but it has also increased the difficulty for special groups such as the elderly and disabled. Home appliances are very daily products for the elderly, however the emergence of new forms and technologies of home appliances has lead them being unable to use basic functions properly. Large smart screens with tons of functions has made it difficult for users to find the key to access; voice operations have made it difficult for them to know how to speak, and so on. The era of intelligence has brought unprecedented technological panic to these special groups.However, despite the fact that the home appliance industry began addressing the issue of product usage for special groups as early as 2000, there has always been a significant challenge. The problem is that once the home appliance design meets the needs of a special group, the product will have "awkward shape", such as the washing machine's buttons being too large to accommodate more functions; The small size of the refrigerator is only for the convenience of elderly people to access, but it affects the volume for daily life required. In a word, although it meets the needs of the special population, it sacrifices the user experience of most people and even affects market sales.The main reason for the problems is the lack of practical and feasible inclusive research and design methodologies for smart home appliances. The main popular methodology is “Microsoft's inclusive design”, but it mainly focuses on software without a specific methodology for smart home products that combine software and hardware. This paper built a research and design methodology for innovative smart home products targeting special and healthy populations.And based on the know-how of R&D, we attempt to overcome this challenge and ensure that products that have been designed by this methodology can meet the needs of special populations for accessible use, while also covering healthy users as much as possible. While gaining a good reputation for humanity design in the market, it can also ensure market efficiency. Finally, the article introduces three successful cases of applying this methodology.

Published: June 2024

With the comprehensive development of the Internet, a plethora of new products continue to emerge. Among these, online education products, serving as crucial tools for knowledge acquisition in the information age, have garnered significant public attention. This article delves into the present state of college students' engagement in online education, with a specific emphasis on the design strategy of self-directed learning platforms within online educational products. By delving into the theoretical underpinnings of the learning process and executing a qualitative analysis of users through Kahle's concept of the list of value (LOV), we have obtained the design model of the self-directed learning platform. Furthermore, we scrutinize and probe into the platform's requirement, function, behavior, structure, and form from a user experience standpoint, culminating in a design model for self-directed learning platforms. And combined with Choudary's platform canvas, the platform architecture of the self-directed learning platform was analyzed. Lastly, we analyzed several typical products, offering invaluable insights for future product development.
The Impacts of Accounting Information on the Cost of Capital of a Company
Authors: Shah Dr. Heer M.
Published: June 2024

The cost of capital is heavily influenced by a company's accounting information. The cost of capital is the rate of return that investors want in exchange for putting their money into a business. Accounting information has an indirect effect on society via things like disclosure and openness. Companies get more trust from investors and the public when they make their financial data easily accessible and easy to understand. Since investors will have a clearer picture of the company's financial performance, they may be more willing to lend money at a reduced interest rate as a result of this greater openness. Another abstract influence is the appraisal of financial success. Investors and lenders use financial statements and other forms of accounting information to assess a company's profitability and financial health. Investors may get a sense of a company's profitability, asset management, and cash flow capabilities by looking at the company's income statement, balance sheet, and cash flow statement. A reduced cost of capital may be possible if financial performance indicators provide a positive picture of the company's financial health. Risk may be better evaluated with the use of accounting data. Financial data is used by investors in assessing the safety of a firm. Investors may get a sense of the company's financial health, leverage, and liquidity by examining financial statements and ratios. A reduced cost of capital is more likely to be offered by investors to a firm that has a good financial position and a low risk profile. In addition to improving openness and easing the evaluation of financial performance and risk, accounting information also affects the cost of capital. The cost of capital might be reduced if investors have more faith in a company because of the transparency it displays in its financial dealings.

Published: June 2024

Food poisoning (FP) has emerged as a global public health concern. Knowledge, attitudes, and practices (KAP) play pivotal roles in mitigating the occurrence of foodborne illnesses. This study aimed to assess the prevalence of KAP in relation to FP prevention and its associated factors among medical students. This cross-sectional study used an online survey platform to select participants through convenience sampling using a structured self-administered questionnaire. Out of 3,126 students, the response rate was approximately 49%. Among the 1,534 participants, 63.0% were females, and the average age was 20.62 ± 1.98. The percentages of participants with good knowledge, good attitudes, and good practices regarding FP prevention were 28.2%, 44.1%, and 68%, respectively. In the multivariate logistic regression analysis, grade level (Year 3 [AOR= 1.98; 95%CI: 1.31-2.99], Year 4 [AOR= 2.30; 95%CI: 1.53-3.46], Year 5 [AOR= 1.52; 95%CI: 1.01-2.30], Year 6 [AOR= 2.59; 95%CI: 1.80-3.72] compared to Year 1), previous participation in courses or subjects related to FP (AOR= 1.66; 95%CI: 1.29-2.14), and hearing about an FP outbreak (AOR= 1.67; 95%CI: 1.24-2.24) were significant factors associated with good knowledge. Females (AOR= 1.28; 95%CI: 1.03-1.59) and participants who had previously participated in courses or subjects associated with FP (AOR= 1.32; 95%CI: 1.04 -1.68) showed significantly good attitudes. Females (AOR= 1.63; 95%CI: 1.29-2.06), participants with no previous history of FP illness (AOR= 0.65; 95%CI: 0.52-0.84), and those with good attitudes (AOR= 3.64; 95%CI: 2.85-4.64) were significantly associated with good practices. This is the first study to provide new insights into the prevalence of KAP towards FP prevention and the contributing factors among Vietnamese medical students. Various health interventions are necessary, primarily focusing on health education targeting key relevant factors.

Hypertension is linked with an increased risk of cardiovascular disease and is the leading modifiable risk factor for morbidity and mortality globally. Lipoprotein (a) is an independent risk factor for atherosclerotic cardiovascular disease. It has been suggested to contribute to increased risk for atherosclerosis in hypertensive patients. This study was to investigate the levels of Lp (a) in hypertensive patients and correlate them with other risk factors of cardiovascular disease. This was a hospital-based cross-sectional study conducted between October 2022 and December 2023 at the Delta State Central Hospital, Warri. The study involved 200 hypertensive patients and 100 healthy controls. The lipoprotein (a) levels in the hypertensives ranged from 5.2 – 89.0 mg/dl with a mean of 32.8 ± 16.6 mg/dl. The controls had a range of 1.1 – 63.2 mg/dl with a mean of 16.9 ± 13.9 mg/dl. The difference in mean Lp(a) levels was statistically significant (p <0.001). In the hypertensives, Lp(a) correlated positively with body weight (r = 0.522, p = 0.001), BMI (r = 0.553, p = 0.002) and waist circumference (r = 0.628, p = 0.001).Serum Lp (a) levels were significantly higher in the hypertensive patients than in the normotensive controls. There was a positive correlation between serum Lp (a) and BMI and waist circumference in the hypertensive group.

Administering the appropriate type and rate of fluids is crucial for pediatric patients. Young patients should be given isotonic solutions, as they are safer than hypotonic solutions for fluid maintenance. However, limited studies exist on the efficacy and complications of isotonic solutions for treating acutely ill pediatric patients with mild dehydration. This study aimed to compare isotonic and hypotonic solutions in such cases. A stratified randomized controlled trial was conducted on patients aged 6 months to 15 years with acute illness and mild dehydration in two disease groups: acute gastroenteritis and other diseases. The trial involved administering intravenous fluids, either isotonic or hypotonic solution, for at least 24 hours. Pre and post-treatment serum sodium levels and treatment complications were assessed and compared between patients who received isotonic and hypotonic solutions. A total of 144 patients were randomly assigned to receive either isotonic solution or hypotonic solution. Of the 144 patients, 72 received isotonic and 72 received hypotonic solutions. The isotonic group comprised 51.4% males with a median age of 27.5 months. On the other hand, the hypotonic group comprised 56.9% males with a median age of 38 months. At baseline, both groups' sodium levels were similar at 136.2±2.5 and 136.8±2.5 mmol/L, respectively. After 24 hours, the isotonic group had a statistically significant increase in sodium levels (138.8±2.2 mmol/L; increased median 2.3) compared to the hypotonic group (138.1±2.0 mmol/L; increased median 1.5). In conclusion, no cases of hypernatremia, drowsiness, or seizures were observed, suggesting isotonic solutions can be safely used in these selected groups of acutely ill pediatric patients with mild dehydration.
Towards Humanitarian Action that Intentionally Promotes Peace in South Sudan

Humanitarian action that promotes peace and addresses the causes of conflict is vital for food security and community resilience in South Sudan. In Upper Nile state, the South Sudan Red Cross (SSRC) has the potential to promote peaceful coexistence and social cohesion, although the peace impacts of its Humanitarian Response (HR) Project are currently unintentional. This paper proposes four theories of change for intentional peacebuilding: The first relates to livelihood opportunities and keeping children in school. The second concerns the connectedness between diverse ethnicities and communities through conflict-sensitive volunteerism. The third consists in helping socialized programme volunteers transition into leadership roles for greater transformational impacts. The fourth involves vertical and horizontal integration with broader development and peacebuilding efforts. Social cohesion could increase if the HR Project has measurable impact in these four areas. This paper provides actionable recommendations that would strengthen the SSRC’s peacebuilding impact while upholding the fundamental principles of the Red Cross and Red Crescent movement.

Justice is one of the attributes of Yahweh. Judges were appointed in ancient Israel by Yahweh for the Israelites to live in peace and harmony with one another. However, it was observed that the Judges in ancient Israel did not live to expectation. Leviticus 19: 15 was chosen as a text of investigation to determine the response of Yahweh to the Judges and its implications for Judges in Nigerian democratic Context. Historical and Phenomenological methods were used for the research. It was discovered that one of the organs that is expected to play crucial roles in governance is the judiciary. The study revealed that Judges and leaders in ancient Israel failed Yahweh. Also, since the inception of Democracy in Nigeria, the Judiciary has played and is playing important roles to protect the system. One of the major roles of the Judiciary is justice and equity for all and sundry in all election petitions, disputes in political parties, removal and reinstatement of elected officer. It was observed that some members of the judiciary are not living to the expectation of the law and the people. Some of them compromise justice for pecuniary gains. Some Nigerians opined that Judiciary has been compromised and as such cannot be trusted in the events of manipulations of electoral process or results by the politicians and the electoral body that has the responsibility of conducting elections. In view of this, many Nigerians no longer have trust in the Judiciary and this has brought the vocation in to disrepute.
A NEW APPROACH TO WIRELESS CHARGING AND ON-DEMAND DATA GATHERING (SSWCODDG) FOR RWSN
Authors: Chandra Pankaj , Santosh Soni
Published: June 2024

These days, WSNs (wireless sensor networks) are all about collecting data and reducing energy use. Mobile sinks and chargers can visit Cluster Heads (CHs) to gather data and recharge their batteries, respectively. A mobile VAN (MV) combines a mobile charger and sinks to improve the energy efficiency of a WSN. Determining the CHs’ guest instructions for wireless data collecting and charging is difficult. In response to these problems, the authors of this study present SSWCODDG (Santosh Soni Wireless Charging and on Demand Data Gathering), a new approach to wirelessly charging and data collection for rechargeable wireless sensor networks. Utilizing mobile VAN, the proposed algorithm gathers data from CHs and charges them according to their choices and needs. Here, Mobile VAN maintains a routing table and, in response to requests, visits CHs. To divide the network into clusters, the proposed method employs the LEACH clustering algorithm. One full cycle is executed by the LEACH (Low Energy Adaptive Clustering Hierarchy) algorithm. To back up its claims, this study compares the recently created SSWCODDG algorithm to the SPSS and M2C algorithms that came before it. In addition, SSWCODDG outperforms SPSS (Single path scheduling scheme) and M2C (Mobile to Cluster) for a range of sensor node densities by 38.62 and 25.78 percentage points, respectively.

Authors: Horpibulsuk Suksun , Suksan Aniroot
Published: June 2024

In this paper, the performance of cement stabilized recycled asphalt pavement (RAP)-Lateritic column inclusion in soft clay was investigated via a physical model. The load-settlement response and bearing capacity of the composite ground was studied at various cement contents (0%, 1% and 3%) and at 30% RAP replacement ratio. The soft clay was consolidated in the PVC mold in a diameter of 150 mm and 300 mm high while the stabilized RAP-lateritic soil column with a diameter of 50 mm was used as a column at the center of the soft clay. The results showed that the bearing capacity of the composite ground significantly increased with the increased shear strength of column. The purposed bearing capacity equation derived from the unconfined compressive strength of column and undrained shear strength of soft clay was found to predict the bearing capacity of the composite ground satisfactorily.

As técnicas construtivas de drywall e bloco cerâmico apresentam características distintas, adaptando-se a diferentes necessidades arquitetônicas e funcionais. O drywall, constituído por placas de gesso acartonado fixadas em estruturas de aço galvanizado, destaca-se pela rapidez na execução, leveza e flexibilidade, permitindo modificações e instalações elétricas e hidráulicas com facilidade. É amplamente utilizado em divisórias internas e forros, proporcionando acabamentos lisos e uniformes. Por outro lado, a construção com blocos cerâmicos envolve a alvenaria tradicional, onde os blocos são assentados com argamassa, oferecendo robustez e isolamento térmico e acústico superiores. Esse método é ideal para estruturas externas e paredes portantes, conferindo durabilidade e resistência ao edifício. Ambas as técnicas possuem vantagens específicas, sendo escolhidas conforme os requisitos do projeto e as condições do local de construção. O artigo aborda a comparação entre as técnicas construtivas de drywall e bloco cerâmico para alvenaria de vedação em projetos de edifícios, com foco em um empreendimento localizado em Vitória da Conquista, Bahia. O objetivo geral é fornecer uma análise abrangente que auxilie na tomada de decisão para a escolha da técnica mais adequada. Especificamente, busca-se avaliar essas técnicas em termos de custo, desempenho, sustentabilidade e praticidade de aplicação, levando em consideração as condições climáticas e as demandas específicas da região. A questão de pesquisa é: Qual técnica construtiva oferece a melhor relação custo-benefício, considerando os fatores econômicos, ambientais e de qualidade da construção? A metodologia adotada é bibliográfica, envolvendo a revisão e análise de fontes relevantes sobre o tema. Os resultados mostram as vantagens e limitações de cada técnica, contribuindo para a otimização do processo de construção e para a qualidade final do edifício.

Introdução: A hipertensão e o diabetes compartilham fatores de risco que levam a uma série de complicações, que resultam em morbilidade e mortalidade prematura. Nesse contexto, o presente estudo possui como objetivo geral avaliar como a hipertensão e a diabetes se comportam no Estado do Piauí. Metodologia: Trata-se de um estudo epidemiológico na base de dados do Datasus, no Estado do Piauí, compreendendo os anos de 2011 a 2013. Foi adotado pacientes hipertensos, com diabetes mellitus tipo 1 (DM1), diabetes mellitus tipo 2 (DM2) e pacientes hipertensos e diabéticos simultaneamente. Referencial Teórico: A HAS é uma doença multifatorial, podendo ser atribuída a várias condições que determinam essa síndrome, dentre ele os fatores genéticos. O sedentarismo, o sobrepeso e a obesidade também tem intima relação com estabelecimento da hipertensão. Além disso, as complicações da DM são sistêmicas e insidiosas e acometem, principalmente, aqueles indivíduos que não fazem uso adequado da terapia, levando a uma importante redução da expectativa de vida nessas pessoas. Resultados e Discussão: Uma parcela dos novos casos de HA atribuíveis ao sobrepeso e obesidade foi de 40% nesta investigação. Além disso, os hábitos de vida desfavoráveis levam ao excesso de peso e, juntos, interferem de maneira significativa na prevalência desses fatores, com consequente aumento da incidência de desfechos cardiovasculares, tais como morte súbita, acidente vascular encefálico (AVE), infarto agudo do miocárdio (IAM), insuficiência cardíaca, doença arterial periférica e doença renal crônica. Conclusão: Percebeu-se que a maior parte das pessoas que possuem hipertensão, apresentam, também, diabetes. Ademais, sobre os fatores de risco estudados, observou-se que todos contribuem para o desenvolvimento da diabetes e hipertensão.
