Published: July 2023

Nicotine, an oxidizing agent, is certainly one of the most widely used alkaloids in the world.It is, together with its main metabolite, cotinine, responsible for tobacco-dependence. The use oftobacco is closely associated with lung disease, morphological leukocyte modification and generationof oxidant species. The aim of this study was to look for a possible relationship between cotinine,oxidant species generation and oxidative processes. After studying the action of cotinine in somechemical oxidation models and on the enzymatic kinetics of peroxidases (myeloperoxidase andhorseradish peroxidase), we concluded that cotinine does not act directly upon H2O2, HOCl, taurinechloramines, horseradish peroxidase or myeloperoxidase.

Published: July 2023

Physico-chemical properties of 3,4-dimethoxybenzoates of Co(II), Cu(II), La(III) and Nd(III)were studied. The complexes were obtained as hydrated or anhydrous polycrystalline solids with a metalion–ligand mole ratio of 1 : 2 for divalent ions and of 1 : 3 in the case of trivalent cations. Their coloursdepend on the kind of central ion: pink for Co(II) complex, blue for Cu(II), white for La(III) and violetfor Nd(III) complexes. The carboxylate groups in these compounds are monodentate, bidentate bridgingor chelating and tridentate ligands. Their thermal decomposition was studied in the range of 293–1173 K.Hydrated complexes lose crystallization water molecules in one step and form anhydrous compounds,that next decompose to the oxides of respective metals. 3,4 – Dimethoxybenzoates of Co(II) is directlydecomposed to the appropriate oxide and that of Nd(III) is also ultimately decomposed to its oxide butwith the intemediate formation of Nd 2 O 2 CO 3. . The magnetic moment values of 3,4–dimethoxybenzoatesdetermined in the range of 76–303 K change from 4.22 μ B to 4.61 μ B for Co(II) complex , from 0.49 μ Bto 1.17 μ B for Cu(II) complex , and from 2.69 μ B to 3.15 μ B for Nd(III) complex.

Unprocessed native starches are structurally too weak and functionally too restricted for application in today’s advanced food technologies. Processing is necessary to engender a range of functionality. Naturals or natives starches can be modified by using several methods physical, chemical, enzymatic or combined, according industrial purposes. In this work, native corn starch was hydrolyzed by hydrochloric acid solution and investigated by using thermoanalytical techniques (thermogravimetry – TG, differential thermal analysis – DTAand differential scanning calorimetry – DSC), as well as optical microscopy and X-ray diffractometry. After acid treatment at 30 and 50°C, a decrease of gelatinization enthalpy (ΔHgel) was verified. Optical microscopy and X-ray diffractometry allowed us to verify the granules contorn and rugosity typical of cereal starches.
Highly sensitive spectrophotometric methods for the determination of olanzapine
Authors: Revanasiddappa Hosakere Doddarevanna , Veena M. A.
Published: July 2023

Highly sensitive and selective spectrophotometric methods (A and B) were developed for the determination of micro amounts of olanzapine (OLZ). Method A (direct method) is based on the oxidation of olanzapine with a known excess of iodine monochloride (ICl) in an acidic medium. Under the same condition, thymol blue was iodinated by unreacted ICl, and the absorbance of uniodinated thymol blue was measured at 536 nm. The decrease in ICl concentration is a measure of drug concentration. In method B (indirect method), oxidation of OLZ by a known excess of Ce(IV) in sulfuric acid medium followed by the reaction of unreacted Ce(IV) with leuco crystal violet (LCV) to crystal violet (CV), which is measured in an acetate buffer medium ( pH 4.9) at 580 nm. These methods obey the Beer’s law in the concentration range of 0.2-1.6 μg mL-1 (method A) and 0.1-1.4 μg mL-1 (method B). The developed procedures have been successfully applied to the determination of OLZ in pure and in dosage forms. The results exhibit no interference from the presence of excipients. The reliability of the methods was established by parallel determination of OLZ against the reference method.

Propolis is a sticky, gummy, resinous substance collected by honeybees (Apis mellifera L.) from various plant sources, which has excellent medicinal properties. This paper describes the isolation and identification of triterpenoids and anacardic acid derivatives from Brazilian propolis and their antibacterial activity. Their structures were elucidated by 1H and 13C NMR, including uni- and bidimensional techniques; in addition, comparisons were made with data from academic literature. These compounds were identified as: cardanols (1a + 1b), cardols (2a + 2b), monoene anacardic acid (3), α-amirine (4), β-amirine (5), cycloartenol (6), 24-methylene-cycloartenol (7) and lupeol (8). The determination of the position of the double bond after a reaction with Dimethyl disulfide (DMDS) isdescribed for the phenol derivatives. The ethanolic extract was tested in vitro for antimicrobial activity by using the disc diffusion method and it showed significant results against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Shigella spp.
Evaluation of group electronegativities and hardness (softness) of group 14 elements and containing functional groups through density functional theory and correlation with NMR spectra data
Authors: Vivas-Reyes Ricardo , Arias Andersson
Published: July 2023

Quantum Chemical calculations for group 14 elements of Periodic Table (C, Si, Ge, Sn, Pb) and their functional groups have been carried out using Density Functional Theory (DFT) based reactivity descriptors such as group electronegativities, hardness and softness. DFT calculations were performed for a large series of tetracoordinated Sn compounds of the CH3SnRR’X type, where X is a halogen and R and R’ are alkyl, halogenated alkyl, alkoxy, or alkyl thio groups. The results were interpreted in terms of calculated electronegativity and hardness of the SnRR’X groups, applying a methodology previously developed by Geerlings and coworkers (J. Phys. Chem. 1993, 97, 1826). These calculations allowed to see the regularities concerning the influence of the nature of organic groups RR’ and inorganic group X on electronegativities and hardness of the SnRR’X groups; in this case, it was found a very good correlation between the electronegativity of the fragment and experimental 119Sn chemical shifts, a property that sensitively reflects the change in the valence electronic structure of molecules.

The advent of online learning has made it necessary for educators to develop new teaching strategies, particularly in the area of questioning techniques. This study aimed to explore the types of questioning strategies employed by teachers during online reading classes and identify the factors that contribute to the frequent use of a specific approach. The study used observation checklists and interview guidelines based on Bloom's taxonomy and Wragg and Brown's questioning strategies to gather data from second-year English language students enrolled in an online reading class. The research findings revealed that to engage students, evaluate their comprehension, and ensure alignment with the textbook material the teacher primarily utilized "Understand" and "Analyze" questions, along with directed, distributed, responded, and sequenced strategies. The teacher also utilized Zoom's chat box feature to ask questions and enable students to provide direct answers. The results of this study demonstrate the importance of effective questioning techniques in online learning environments. The teacher's use of a variety of questioning strategies had a positive impact on the students' ability to acquire knowledge, demonstrating that a diverse range of strategies can help students achieve deeper levels of understanding. The research findings have important implications for the education sector as it provides insights into effective teaching strategies that can help promote student engagement and enhance their learning outcomes.

Docência masculina: perfil e representações de gênero e bem-estar docente entre profissionais da educação
Authors: Gonçalves Josiane Peres
Published: July 2023

O presente estudo teve como objetivo investigar e analisar a perpectiva de docentes do gênero masculino brasileiros sobre o bem-estar docente. O referencial teórico fundamenta-se nos estudos de gênero e estudos sobre o bem-estar e mal-estar docente. A pesquisa qualitativa utilizou entrevistas semiestruturadas individuais com cinco professores homens, entre 38 e 64 anos, que fizeram a opção pelo magistério como principal profissão. Os resultados apontaram que em outros contextos históricos o trabalho docente era mais valorizado e ser professor era visto como referência para outras pessoas, mas com o tempo isso mudou e, consequentemente, resultou em situações de mal-estar docente. Quanto ao lazer, os professores entrevistados aproveitavam o tempo livre para: ficar com a família, dormir bem, se desligar do trabalho, brincar com os filhos, entre outras iniciativas. Eles acreditavam que fatores como gostar da profissão, ter boas condições de trabalho, investir na formação profissional, ser sujeito ativo do processo educativo, ter o reconhecimento social, entre outras, contribuem para a vivência do bem-estar docente.

Background

The burden of chronic hepatitis B virus (HBV) varies across the European Union (EU) and European Economic Area (EEA).

Aim

We aimed to update the 2017 HBV prevalence estimates in EU/EEA countries and the United Kingdom for 2018 to 2021.

Methods

We undertook a systematic review, adding to HBV prevalence estimates from an existing (2005–2017) database. Databases were searched for original English-language research articles including HBV surface antigen prevalence estimates among the general population, pregnant women, first-time blood donors (FTB), men who have sex with men (MSM), migrants and people in prison. Country experts contributed grey literature data. Risk of bias was assessed using a quality assessment framework.

Findings

The update provided 147 new prevalence estimates across the region (updated total n = 579). Median HBV prevalence in the general population was 0.5% and the highest was 3.8% (Greece). Among FTB, the highest prevalence was 0.8% (Lithuania). Estimates among pregnant women were highest in Romania and Italy (5.1%). Among migrants, the highest estimate was 31.7% (Spain). Relative to 2017 estimates, median prevalence among pregnant women decreased by 0.5% (to 0.3%) and increased by 0.9% (to 5.8%) among migrants. Among MSM, the highest estimate was 3.4% (Croatia). Prevalence among people in prison was highest in Greece (8.3%) and the median prevalence increased by 0.6% (to 2.1%).

Conclusions

The HBV prevalence is low in the general population and confined to risk populations in most European countries with some exceptions. Screening and treatment should be targeted to people in prison and migrants.
Strategies employed for information transfer and relation building in intercultural communication – A cross-cultural study
Authors: Kiliańska-Przybyło Grażyna
Published: July 2023

The aim of the study is to examine strategies used in intercultural encounters by Polish and Turkish students of Foreign Languages (n1=50, n2=50, respectively) who have experienced intercultural communication. Intercultural encounters are viewed as ‘language-in-action’ situations because they provide a rich source of information about linguistic devices used during intercultural exchanges, sources of misunderstanding and miscommunication, and strategies implemented to transfer information or maintain conversational involvement of the interlocutors. This study offers some insights into the frequency and variety of the strategies used in intercultural encounters. It was conducted as a small-scale project, with the Critical Incident Technique and questionnaires administered to collect data. The research participants (C1/C2 levels of proficiency) were supposed to produce written narratives describing the most memorable intercultural encounters and report on intercultural communication strategies. Their narratives were later analysed to identify strategies applied to manage intercultural communication and achieve communicative goals (e.g. maintaining contact and/or conveying necessary information). Research findings show that Proactively seeking clarification and Building intercultural connection or relationship were the most frequent strategies used by these two groups. However, research results also suggest that the choice of strategies depends on such factors as the participants’ level of language proficiency, their cultural background or the quality and quantity of intercultural contacts. Cross-cultural analysis indicates that Turkish students are more socially- and culturally oriented, whereas Polish students display a tendency to focus more on cognitive and linguistic aspects of intercultural encounters. Findings from the study can be of help for educators and trainers involved in researching intercultural communication, strategic involvement and training.
Inner speech as a brain mechanism for preconditioning creativity process

Published: July 2023

The current domain of creativity studies is characterized by a high diversity of psychological and neuroscience techniques and methods researchers use. However, the role of verbal processes, especially inner speech, remains underrepresented in this area. Existing studies point to the heterogeneity of inner speech brain mechanisms involved in creative thinking. While consciously controlled verbalized thoughts are associated with the activity of task-dependent brain networks (TPN), especially lateral-frontoparietal network (L-FPN), non-voluntary, mind-wandering thoughts are supposed to correlate with default-mode networks (DMN) activity. While DMN activity leads to an increased number of creative ideas, L-FPN activity results in fewer ideas but increased idea originality. From this point, rest state and state of getting prepared (preconditioning) to task completion, when both mind-wandering and control thoughts occur, are of specific interest. In our study, 49 volunteers completed divergent thinking tasks with rest state and preconditioning state preceded. We later divided all participants into two groups – with low and high creativity levels based on their performance during divergent tasks. EEG was recorded during rest state and preconditioning state and analyzed based on power spectrum and sLORETA data. Our results show an essential role of preconditioning alpha-2 EEG subband in creative thinking performance. The originality of the task solution correlates with the activity of L-FPN structures, while DMN activity does not differ significantly between the two groups.

Authors: Suhra Sarifa , Rosita Rosita
Published: July 2023

Child marriage remains a persistent issue in Bone County, as evidenced by the high number of cases reported in 2019. While there has been some reduction in child marriage due to government intervention and Unicef cooperation in select villages, the problem persists. NU Muslimat has implemented various strategies to raise awareness and prevent child marriage to combat this. The study employed the ABCD method and found that community service effectively raised awareness among majelis taklim members and their children. Furthermore, the da'iyah training produced professionals capable of counseling against child marriage, while the peer tutor training involved individuals who conducted counseling sessions and created awareness materials. As a result of these interventions, members of the community and students expressed strong determination to avoid child marriage, demonstrating the positive impact of NU Muslimat's initiatives.

Published: July 2023

O comportamento ecotoxicológico de fluidos de perfuração pode ser estudado pela relação entre a ecotoxicidade de um fluido com suas propriedades físico-químicas e a concentração de seus componentes. Por se tratar de uma mistura complexa, os componentes do fluido influenciam de formas diferentes na ecotoxicidade da mistura. De posse de uma base de dados contendo resultados de testes de ecotoxicidade de amostras de fluidos de perfuração conhecidas, pode-se aplicar técnicas de mineração objetivando a previsão e extração de conhecimento, que pode ser empregado em ferramentas de análises de risco e tomada de decisão. Este artigo tem como objetivo elaborar uma revisão sistemática da literatura para responder à questão de pesquisa: qual a previsão do comportamento toxicológico de fluidos de perfuração, conhecida a sua composição e suas propriedades físico-químicas, por meio de técnicas computacionais de análise de dados de testes de ecotoxicidade aguda? Para tanto, foram utilizadas três bases de dados e os resultados mostraram que a toxicologia computacional (in silico) tem sido amplamente utilizada na previsão de toxicidade, contudo não há estudos relacionados a fluidos de perfuração nas bases de dados utilizadas.

O setor da construção tem se tornado um dos grandes motivos de preocupação ambiental, principalmente quando se trata da emissão de dióxido de carbono e geração de resíduos. Uma forma de mitigar tais impactos consiste na substituição de um sistema linear para um modelo de Economia Circular (EC). Nesse modelo, a reciclagem de Resíduos de Construção e Demolição (RCD) consiste em uma prática bastante estudada há mais de 20 anos, enquanto pesquisas sobre o reuso de elementos construtivos a partir da metodologia de projetar para desconstrução (DfD, Design for Deconstruction/Disassembly) tem ganhado destaque apenas nos últimos cinco anos. Dentre tais pesquisas, a avaliação da sustentabilidade por meio de indicadores ambientais é ainda mais escassa. Desta forma, o presente artigo faz uma revisão sistemática da literatura, reunindo trabalhos que apontam os principais avanços da prática DfD, com foco em estruturas de concreto armado sob a perspectiva da Avaliação do Ciclo de Vida (ACV). Com base nos artigos analisados, foi observado que, apesar da ausência de método unificado para quantificar seus benefícios, a prática de DfD se mostrou vantajosa para atenuar os impactos ambientais do setor da construção.

Na atualidade, o uso irracional da água nas cidades torna-se um dos fatores que contribui para agravar várias problemáticas como a poluição e a escassez destes recursos. A literatura aponta vários desafios como o consumo irresponsável, a falta de reservas naturais e ausência de tecnologia adequada. Cabe compreender estas tecnologias e seus sistemas na contemporaneidade. O artigo questiona de que forma a literatura aborda as relações entre a tecnologia, sistemas, água e inteligência. O estudo visa realizar uma revisão da literatura sobre os esforços de pesquisas acerca dos sistemas inteligentes de água. Para a revisão utilizou-se diferentes bases de dados com publicações entre 2020 a 2022. Destes, 18 artigos científicos foram analisados. Notou-se a utilização das tecnologias na oferta de soluções para os problemas ambientais da escassez de água. Apontamos soluções que contribuem para o desenvolvimento da região e das cidades e podem transformá-las em cidades mais inteligentes.

O presente trabalho avalia o impacto ambiental causado por obras de arte especiais (OAE), neste caso, quatro pontes de concreto armado. O principal objetivo foi a avaliação dos impactos considerando o processo de produção de elementos estruturais de concreto armado. As pontes são obras de infraestrutura de cidades e rodovias essenciais para a economia da sociedade. Não há muitos estudos que apresentem resultados de avaliação de impactos ambientais causados por essas construções. Neste contexto, a pesquisa se ateve à avaliação da fase pré-operacional do objeto que visa levantamento dos consumos de materiais utilizados na construção dos elementos estruturais dessas OAE. Utilizou-se da abordagem quantitativa-qualitativa por meio do programa OPENLCA versão 1.11.0 e a base de dados ecoinvent35_APOS_UP_20181210 fornecida pela Ecoinvent. Foi realizada a análise dos impactos apenas para o compósito concreto armado. Nesta análise, tanto o aço quanto o concreto apresentaram contribuição significativa para a degradação do meio ambiente. Percentualmente, o aço se sobressai ligeiramente, sendo responsável por 52,7% das contribuições computadas, enquanto o concreto se responsabiliza por 47,3%.

A dimensão social do Design para a Sustentabilidade possui algumas formas possíveis de abordagem para os diferentes públicos (SANTOS, et al, 2019), sendo que para este trabalho foi preferível a busca de soluções para mulheres em situação de vulnerabilidade social, mais especificamente para adictas de um centro de reabilitação, localizado em Maringá, no noroeste do Paraná.

Com o objetivo de atuar nesse segmento social do design, decidiu-se abordar o desenvolvimento de joias, cuja aplicação é plausível devido à possibilidade de desenvolvimento com valores agregados. A escolha da joalheria é associada pela sua relevância simbólica desde os primórdios, (SALEM, 1998), com importância histórica e valorização simbólica, também como representação de status, pertencimento social, e outros tipos pertinentes a cada cultura que a utiliza (SKODA, 2012).

Além desta, torna-se relevante pela necessidade do desenvolvimento sócio-ambiental e econômico, e potencial de inovação dentro da área do Design (MANZINI, 2008). Sendo que, como foi utilizado estes assuntos para um trabalho de conclusão de curso, focou-se no “Desenvolvimento de processos e técnicas para joalheria sustentável, utilizando resíduos sólidos urbanos, visando a confecção de catálogo para geração de renda de mulheres em situação de vulnerabilidade social” de maneira a propor soluções utilizando resíduos sólidos urbanos, com potencial de reciclagem, da região de Maringá-PR como matéria-prima.

Inclui-se, neste projeto, a importância de repensar sobre os resíduos gerados. Isso pois o caso estudado para o trabalho, que se baseou no método de pesquisas documentais, normativas, de campo com setores envolvidos e também estudos de caso com abordagem prática e curso para comprovação de aplicação projetual com o público escolhido, revelou que os materiais que as mulheres mais possuíam familiaridade eram os que eram envolvidos em centros de reciclagem, local onde muitas trabalharam antes de serem adictas. Portanto, os dados revelaram a possibilidade de confecção de peças ser uma área de sucesso, por terem sido encontrados processos que sejam menos onerosos e que as mulheres conseguiriam desenvolver.

A importância do projeto também está na inserção de pautas mundiais (ONU MULHERES, 2016), sendo que, em 2018, a ONU Mulheres criou um projeto em parceria à Movimento Mulher 360, com o objetivo de contribuir para o empoderamento econômico feminino na indústria de modo geral. Além disso, a questão da igualdade de gênero, incentivo à geração de renda e incentivo a comunidades sustentáveis e produção consciente estão presentes em alguns dos 17 Objetivos de Desenvolvimento Sustentável da ONU.

O pó de balão e a escória de aciaria são dois resíduos gerados na indústria siderúrgica com potencialidade de uso como agregados na construção civil. O bloco de solo-cimento permite realizar construções de mais baixo custo e sustentáveis. O objetivo deste trabalho é quantificar o aumento de desempenho nos blocos de solo-cimento devido a utilização de uma mistura de pó de balão e escória de aciaria. O percentual de incorporação dos mesmos à mistura variou de 0% a 8% do total da massa. Os parâmetros avaliados foram a absorção de água e a resistência à compressão dos blocos. A substituição do resíduo pelo solo não alterou os valores de absorção de água, sendo sempre estes valores os exigidos pela normativa (absorção abaixo de 20%). No caso de substituição do solo pelo resíduo em uma quantidade de 8%, com respeito à massa total do solo, o aumento da resistência à compressão foi de 15%. Para todos os traços estudados a resistência à compressão sempre foi superior à exigida pela normativa (>2,0 MPa). Se conclui que o uso do bloco de solo-cimento nas construções com a utilização deste resíduo gera uma economia da obra e uma melhora nos aspectos ambientais.

Monitoring of phytopathological situation in crops is the basis for biological justification of the need for protective measures, allowing to obtain a yield close to the potentially possible. The results of phytopathological situation monitoring in crops of spring wheat varieties are presented in the paper. Studies were carried out in 2019–2021 in the laboratory of phytopathology and in the experimental field of the Institute of Plant Protection. Standard methods in phytopathology were used during the work. The main criteria for assessing the degree of plant infestation were disease development (%) and area under disease process curve (AUDPC, in conditional units). Analysis of phytopathological state of spring wheat crops showed that during the growing season the crop varieties were affected by diseases of vegetative and generative organs: root and byroot rots, powdery mildew, leaf and ear septoriosis, pyrenophorosis, brown rust, and fusariosis of ear. Root rot, leaf spot disease, septoriosis, and spikelet fusariosis are among the dominant diseases annually present in spring wheat crops. Variety differences in disease incidence are a factor influencing the emerging phytopathological situation in the crop. Cultivation of resistant varieties reduces the risk of epiphytotics. According to the sum of infectious loads experienced by the plants during the whole period of vegetation, the evaluated varieties of spring wheat were ranked in ascending order: Lyubava (60,5 %), Slavyanka (61,9 %), Sudarynya (66,9 %), Laska (71,3 %), and Darya (83,9 %). The results of the studies allow to give preference to the most interesting varieties, based on the available opportunities to ensure the proper level of protection against diseases.

Complaints on unpleasant odor occurring near pig-breeding complexes and frequently, at a considerable distance from them, are one of the key factors that are limiting the development of pig-breeding industry. Unpleasant odor takes place as a result of anaerobic decomposition of the manure and also due to liquid slurry at the pig-breeding facility. Despite the fact, that the effect of unpleasant odor on human health is under-investigated, the people suffer natural aversion to the smell of manure. The smell of swine manure can be an unpleasant factor affecting the quality of the life of people living in the cities close to the pig-breeding complexes and also have an effect on the price of the real estate located within this area. Tightening of standards regulating the level of odor can also be a limiting factor for this branch of industry. Detailed research aimed at the selection of the optional composition of chemical reagents for deodoration and disinfection of liquid slurry waste at a pig breeding complex is presented. It has been determined, that the effect of disinfection and suppression of unpleasant odor for a long time is provided by the composition of ammonium persulphate, peracetic acid and formalin, the composition that contains sulphuric acid, sodium hypochlorite and sodium hydroxide and finally, the composition that contains sodium nitrite and ammonium molybdate. It was showed that the abovementioned mixtures are effective in relation to the samples of manure in laboratory (the volume of manure taken for the experiment was 200-400 ml), as well as semi-industrial conditions (the volume of manure – 80 liters). The manure mixtures obtained as a result of such treatment are environmentally friendly and can be used for the production of organo-mineral fertilizers.

Gangguan kognitif terkait hipertensi memiliki spektrum yang luas, mulai dari gangguan kognitif ringan sampai dengan gangguan kognitif berat pada penderita hipertensi. Hipertensi saat ini diketahui sebagai salah satu faktor risiko untuk terjadinya demensia Alzheimer dan demensia vaskuler. Pada bentuk yang berat, penderita gangguan kognitif akan memiliki ketergantungan yang tinggi kepada anggota keluarganya untuk melakukan aktivitas sehari-hari. Dengan demikian, pasien etrsebut akan menjadi beban sosial dan ekonomi bagi keluarganya. Kegiatan pengabdian kepada masyarakat ini ditujukan untuk meningkatkan pemahaman para penduduk Desa Pulau Maringkik mengenai pentingnya upaya pencegahan dan deteksi dini untuk terjadinya gangguan kognitif terkait hipertensi. Kegiatan ini dilaksanakan di Desa Pulau Maringkik, Kabupaten Lombok Timur, sebagai representasi wilayah pesisir yang umumnya penduduknya memiliki tingkat konsumsi natrium yang tinggi. Kegiatan ini dilaksanakan dalam 3 bentuk kegiatan: penyuluhan kesehatan, penapisan hipertensi, dan deteksi dini gangguan kognitif terkait hipertensi. Kegiatan penyuluhan ini diikuti oleh 53 partisipan. Sebagian besar partisipan adalah perempuan dengan tingkat pendidikan relatif rendah rendah. Dari jumlah tersebut, sebanyak 29 partisipan (54.7%) menderita hipertensi. Pada kegiatan deteksi dini gangguan fungsi kognitif, dari 29 partisipan penderita hipertensi, sebanyak 19 partisipan (65,5%) diantaranya memiliki gangguan fungsi kognitif. Dengan demikian, dalam kegiatan pengabdian kepada masyarakat ini, kegiatan penyuluhan, penapisan hipertensi, dan deteksi dini gangguan kognitif terkait hipertensi berjalan dengan baik. Frekuensi penduduk Desa Pulau Maringkik yang mengalami hipertensi dan penurunan fungsi kognitif terkait hipertensi cukup tinggi. Upaya promotif perubahan kebiasaan konsumsi tinggi garam natrium perlu dilakukan secara berkesinambungan dengan strategi edukasi yang sesuai dengan tingkat pendidikan partisipan.
