Authors: Elias Henrique Rizek , Ribeiro Rodrigues Silmara , Trevisan André Luis
Published: May 2022

Esta pesquisa possui dois objetivos: (i) analisar o conhecimento matemático para o ensino mobilizado por uma professora quando participa de um ciclo de Estudo de Aula; e (ii) apresentar o processo de construção de uma Tarefa de Aprendizagem Profissional (TAP), elaborada a partir de amostras autênticas da prática obtidas dos dados produzidos durante um ciclo do Estudo de Aula. Fundamentadas na tabela teórica do Conhecimento Matemático para o Ensino (MKT), as análises foram realizadas a partir de dados produzidos no contexto de uma formação continuada de professores que ensinam Matemática nos anos iniciais do Ensino Fundamental. Assim, com base nos subdomínios do MKT, as análises consideram dados produzidos em cada momento de um ciclo de Estudo de Aula: planejamento coletivo de uma aula, desenvolvimento dessa aula por uma professora, Maria, em sua turma de 5º ano do Ensino Fundamental e reflexão dessa aula. Após essa análise, elaboramos uma TAP, cujo objetivo é promover discussões matemáticas e didático-pedagógicas com vistas a mobilizar subdomínios do MKT para o ensino dos números racionais nos anos iniciais. Os resultados indicam que o Estudo de Aula, uma abordagem para a formação de professores estreitamente relacionada com a prática, oportuniza momentos para o desenvolvimento/refinamento do MKT, conforme verificado a partir dos subdomínios mobilizados pela professora Maria. Esta pesquisa também sugere um caminho para se produzir uma TAP, utilizando amostras autênticas da prática a partir dos três momentos do ciclo do Estudo de Aula, inclusive o momento de reflexão da aula feita pelos professores enquanto trabalham colaborativamente.

Authors: Teixeira Paulo Jorge Magalhães
Published: May 2022

Trabalho que objetiva tornar conhecida proposta de ensino aprendizagem acerca de conteúdos básicos de combinatória e probabilidade, por meio de um jogo de tabuleiro nomeado Grelha Retangular 3 x 4. A proposta visa fomentar a apropriação, exercício e desenvolvimento do raciocínio combinatório, enquanto um diagrama de árvore é construído com o objetivo de mostrar possibilidades como uma partida pode se desenrolar a partir de tomadas de decisão dos jogadores por ocasião da movimentação de tampinhas de garrafa pet sobre o tabuleiro. O desenrolar da análise das possibilidades pode se dar logo após o início de uma partida (antes da primeira movimentação) ou a partir de um dado momento de jogo, até que a partida chegue ao seu final. Também fomenta o exercício e o desenvolvimento do raciocínio probabilístico, com o propósito de determinar chances de vitória para cada jogador, e de ocorrência de empate. Em prosseguimento e o consequente reconhecimento das regras do jogo, problemas de probabilidade devem ser propostos aos jogadores, conforme preconiza a teoria de Resolução de Problemas. A proposta do jogo está em consonância com indicações que estão presentes na BNCC – Base Nacional Curricular Comum para o ensino aprendizagem de Matemática nos anos iniciais do Ensino Fundamental. Trata-se de uma pesquisa bibliográfica, que culminou com a proposta do jogo, que tem como objetivo dimensionar a importância da proposição e criação de um jogo que contribua para melhorar o processo de ensino aprendizagem da Matemática de estudantes dos anos iniciais, e dispor um material didático para os seus professores.

Authors: Lima Reinaldo Feio , Nogueira Clélia Maria Ignatius , Boscarioli Clodis
Published: May 2022

Mediante a análise de publicações científicas brasileiras, o objetivo deste estudo exploratório é identificar o que as pesquisas em Educação Matemática Inclusiva que consideram tecnologias digitais apontam sobre a prática pedagógica do professor. Como procedimentos metodológicos, utilizamos pressupostos de um mapeamento na concepção de Fiorentini. Os resultados indicam que a inserção de tecnologias conduz ao deslocamento das práticas pedagógicas, que acontecem em um contexto diferente da sala de aula comum e de forma pontual no momento do desenvolvimento do conteúdo matemático, enquanto a integração de tecnologias na prática pedagógica promove ações pedagógicas compartilhadas, caracterizadas pela interação constante entre professores e estudantes. As análises efetuadas mostram que essas duas práticas pedagógicas podem acontecer concomitantemente no mesmo contexto escolar, pois ambas possibilitam subsídios para a reflexão sobre inclusão digital e o uso gradativo das tecnologias por estudantes assistidos pela Educação Especial.

Published: May 2022

Background: Food allergy is a costly health issue that can have a negative impact on a patient's well-being. The current study aims to evaluate the quality of life of patients with food allergies using the healthcare system, coping strategies, management knowledge, and environmental safety.
Methods: This was a descriptive cross-sectional, survey-based study, including patients with food allergies in the Makkah region, Saudi Arabia. To achieve the study's aim, an online survey with 21-items was created and distributed between April and June 2021. Data were exported automatically to Excel onto Statistical Package for the Social Sciences for analysis.
Results: A total of 90 food allergy patients were included. About two-thirds (67.8%) had anaphylaxis. The most common reported food allergies were eggs and seafood equally (44.4% for each), followed by some types of fruits (41.1%), then nuts (25.6%). Regarding using the healthcare system, (63.3%) were diagnosed with food allergy by a doctor, and only (13.3%) routinely followed up. Excellent management knowledge was detected among (65.6%) of the participants. Around a third (36.7%) have at workplace/school a certified first-aid provider for allergic food reactions. For coping strategies, the patients were open to sharing their health condition with their family and friends (88.9% and 51.1%, respectively) compared to carrying a card or a self-injection of epinephrine (1.1% for each item).
Conclusion: The current study revealed excellent levels of knowledge among food-allergic patients. Nevertheless, poor practices toward the healthcare systems and inadequate environmental safety were observed. Educational projects for food-allergic patients are critical.
Do departmental simulation and team training program reduce medical error and improve quality of patient care? A systemic review
Authors: Almulihi Qasem , Muslim Duaa , Alturki Aminah , Shujaa Asaad
Published: May 2022

Aim: Simulation-based learning programs have become increasingly popular over the past 20 years to improve healthcare professionals' knowledge, skills, and attitudes while protecting patients from unnecessary risks and errors. However, recommended practices for simulations in healthcare are still unknown; hence this systematic review aimed to assess whether human simulations or machine stimulations programs would help prevent medical errors and improve patient safety.
Methods: We searched for all the publications in the Medline, Web of Science, and Google Scholar databases from January 2000 (when the idea of simulation in healthcare to prevent Medical Errors (ME) was employed for the first time by the Institute of Medicine) to Feb 2022 with only English language-based literature. The risk of bias from A randomized controlled trial (RCTs) was assessed through Cochrane's collaboration tool. The Newcastle-Ottawa Scale was used to evaluate the quality of the cohort studies. The main outcome of this review was the improvement in professional skills among healthcare professionals and reduction in medical errors by employing simulation-based training.
Results: Overall, the participants who received simulation-based training for the management of different clinical conditions and for the performance of various diagnostic, therapeutic, and surgical procedures showed better learning than those who were given traditional education and training. Moreover, the studies showed that simulation-based training can improve self-efficacy, confidence, and perceptions among medical professionals. Different simulated adult and pediatric scenarios were created to assess the errors and delays during drug infusion-preparation and administration. The simulation was demonstrated to be an effective way of reducing medical errors.
Conclusions: By incorporating simulation-based training into medical education curricula, the acquisition of knowledge and professional skills can be improved. Moreover, this can help improve patient outcomes and reduce medical errors. Based on our findings, we suggest that simulation can be best used as a complement to the other methods of healthcare professionals' teaching and training.

É trazida à baila a relevância jurídica, os efeitos e consequências deste instituto, o qual, inclusive, já foi alvo de críticas quanto à possibilidade de causar insegurança jurídica no ordenamento pátrio. Com isso, a presente pesquisa também tem por objetivo investigar se o magistrado, dotado de discricionariedade, é limitado quando do uso das cláusulas gerais, caso positivo, quais limites são, bem como se a referida técnica, de fato, contribui para a consolidação jurisprudencial. Por fim, tendo em vista tratar-se de uma técnica legislativa utilizada como fundamentação pelos magistrados em suas decisões, nada melhor que analisar alguns entendimentos jurisprudenciais.
A criação de uma clientela preferencial do direito penal: uma crítica constitucional para o Brasil contemporâneo
Authors: Terra Bibiana de Paiva , Vieira da Silva Filho Edson , Helena Vieira da Silva Marina
Published: May 2022

O presente trabalho tem como objetivo elaborar uma análise crítica acerca da criação de uma clientela preferencial do direito penal no Brasil contemporâneo. Para tanto, primeiramente, explora o direito penal máximo versus o direito penal mínimo, por entender que, cada vez mais, esses modelos penais se entrincheiram em uma disputa acirrada. A partir disso, aborda a teoria do etiquetamento (labeling approach), a clientela preferencial do direito penal e, por fim, o direito penal do inimigo. A pesquisa traz como resultados o entendimento de que o direito, especialmente o penal, deve ser entendido como uma instância subsidiária da gestão do poder em sociedade, sendo que o Estado não pode adotar um modelo repressor que ignora garantias penais e constitucionais para atender a anseios sociais. A seletividade penal é incompatível com um modelo de estado plural, social e democrático, como o adotado pela Constituição de 1988. Foram utilizados como referenciais teóricos da pesquisa Alessandro Baratta e Eugenio Raúl Zaffaroni.

Published: May 2022

The education system requires egalitarian practices of transparency and quality. Formative and Shared Assessment (F&SA) is an educational model that allows students to participate in their learning. Training in F&SA can be provided through In-Service Teacher Education (ISTE) and Action-Research (A-R) cycles. The research objectives are: (a) to analyse the participation of students in all educational stages through F&SA, before and during the COVID-19 confinement; (b) to define the advantages of belonging to a group of ISTE in which A-R is carried out and the proposals for improvement proposed by the participants of the same. A case study was carried out with 24 teachers from an inter-level seminar on ISTE about F&SA. Two questionnaires, a focus group and the minutes of the seminar meetings were used. The results show that the teachers of the seminar value positively the participation of the student in their own assessment, understand the individuality of the students and avoid exclusion with egalitarian practices, especially during the confinement situation, where they used various strategies to ensure that the distance process was followed safely. In terms of the advantages of belonging to the seminar, the collaborative learning between teachers from different stages and the usefulness of A-R systems stand out.

Los objetivos del estudio fueron: (i) estudiar las correlaciones entre las variables de inteligencia emocional (IE) y satisfacción con la vida (SWL); (ii) analizar las diferencias entre IE y SWL en función de la variable sexo; (iii) analizar la relación de predicción de la IE sobre la SWL. Se utilizó un diseño observacional y descriptivo de carácter transversal, con una selección de la muestra de tipo no probabilístico y por conveniencia. Se usaron los siguientes instrumentos: The Emotional Quotient Inventory (EQ-i) y Escala de Satisfacción con la Vida. Partciparon 274 estudiantes de primaria y secundaria (Medad=10.96; DT=2.33). Las diferencias según sexo se calcularon con T de Student, y para valorar la predicción de las subescalas de IE (variables predictoras) sobre la SWL (variable criterio) se realizó un análisis de regresión lineal. Los resultados reflejaron que existen correlaciones significativas entre la IE y la satisfacción con la vida. Además, los valores de inteligencia intrapersonal y adaptabilidad de la IE son significativamente más altos entre los chicos, datos que se diferencian de los obtenidos hasta ahora y que podrían haberse visto influenciados por la pandemia de COVID-19, mientras que en la subescala de adaptabilidad los valores son significativamente más altos en las chicas. En la satisfacción con la vida, los chicos presentan valores significativamente más altos que las chicas. La IE predice satisfacción con la vida, aunque las variables de predicción son diferentes en chicas y chicos.

Published: May 2022

COVID-19 Pandemic has impacted Higher Education worldwide, resulting in school closures to enforce social distancing protocols. Educational Institutions face profound changes in planning, implementing, and assessing their system, particularly in the Philippines. There is meager research on how COVID-19 influenced the educational system in the academic profession. As a result, this study utilized a Qualitative Phenomenology Research Design to explore further the information concerning private tertiary students' experiences learning physical education in the context of the COVID-19 Pandemic. Specifically, this study investigated the Private Tertiary Students’ lived experiences, coping mechanisms, and generated sensible suggestions to better implement the Tertiary Physical Education amidst the COVID-19 crisis. Using purposive sampling technique, 35 participants from private tertiary schools in the Cotabato Province in the Philippines took part in this qualitative research. Using open-ended questions as main instrument for the interviews, the necessary data were gathered and analyzed using the framework developed by Miles and Huberman - data reduction; data display; and conclusion drawing and verification. The findings of this study conclude that the lived experiences of private tertiary students were influenced by resource availability, support, and management, teaching and learning strategy, and student-teacher engagement. Improvements to facilities and equipment must be another focus of the school to increase students' learning experiences and boost their interest in physical education, which is essential for obtaining the desired performance rate and level of physical competence in the curriculum. Thus, this study implies that teachers should work conducive to professional growth and must interact with the learners and utilize adequate and efficient teaching strategies for the online learning of physical education. The findings were then used to develop conclusions and recommendations that can be used to improve and design interventions in online learning of physical education in the Philippine Private Tertiary schools.

Published: May 2022

Every child deserves access to quality education amidst the COVID 19 pandemic. Students face the test of answering modules much more than doing the performances in the physical education classes. One of the challenges they faced was performing different performance tasks and being able to meet the objectives as well as the learning competencies. This study aimed to determine the barriers in learning performances and students’ coping strategies in physical education in modular distance learning which was accompanied by a quantitative approach using a descriptive – survey method of research. The study was conducted in one of the secondary public schools composed of 201 selected junior high school students. Based on the result of the study, the findings were as follows: majority of the of the respondents were female, grade 9 students and 15 years of age. The barriers exprienced by the students were overthinking about their grades, minimal engagement in performance tasks due to lack of equipments and learning materials, discomfort in doing the task because of  distraction at home and unstable internet connection which means it is important to assess and evaluate the learning materials provided in the module to provide accessibility to students capabilities and available materials at home. With regards to students’ coping strategies,  it emphasize in developing skills and abilities even in the confinement of home because learning must continue and students have the grit to do their tasks in their modules which indicates the student's opportunities and resiliency was very important factors for the students’ learning and doing performances. To satisfy the students' needs, school leaders must incorporate real methods into their teaching and address their diversity, as well as provide a variety of instructions and learning resources, lesson exemplars, and assistance for the students. To stimulate creativity and assure excellence in educational offerings, colleagues should be given technical assistance and coaching. Professional development should be prioritized during the pandemic to improve intrinsic competencies to plan, manage, and internalize more effective service delivery.

Published: May 2022

Selective functionalization of indole C3-C bond with aromatic/heteroaromatic 1,2-diketones has been uncovered for the first time. Earth crust abundant first-row transition metal cobalt catalyst has been demonstrated as an effective catalyst for this unusual transformation. Furthermore, the use of easily available weakly coordinating groups such as ketone and ester was found to be effective. The key feature of this methodology is the in-situ generation of water from hexafluoro-2-propanol and the removal of the pivaloyl/ester group in a decarbonylative manner at a lower temperature. In addition, photophysical studies show the potential utility of indole (C3)-acyloin and indolo-fused carbazole, in photovoltaic and optoelectronic applications
Taurine electrografting onto porous electrodes improves redox flow battery performance
Authors: Boz Emre B. , Boillat Pierre , Forner-Cuenca Antoni
Published: May 2022

The surface properties of porous carbonaceous electrodes govern the performance, durability, and ultimately the cost of redox flow batteries. As prepared, commercially available carbon fiber electrode interfaces suffer from limited kinetic activity and incomplete wettability, fundamentally limiting the performance. Here, we propose electrografting as a versatile and facile technique to enable task-specific functionalization of the ubiquitous carbon fiber-based porous electrodes. We elect to investigate taurine as a model molecule as the sulfonic acid group is anticipated to provide hydrophilic and active interfaces whereas the amine group allowing covalent attachment to the carbon surface would enhance stability. We perform hydrodynamic voltammetry and find enhanced kinetic rates of taurine treated model electrodes and flow cell experiments reveal superior mass-transport properties of taurine treated porous cloth electrodes. Additionally, we perform operando neutron radiography to visualize electrolyte infiltration within the electrode in a flow cell setup and find superior wettability of porous electrodes functionalized with taurine. Electrografting emerges as a promising technique to functionalize three-dimensional porous electrodes for redox flow batteries and other electrochemical technologies for energy conversion and storage.
Graph neural network modeling of vacancy formation enthalpy for materials discovery and its application in solar thermochemical water splitting
Authors: Witman Matthew , Goyal Anuj , Ogitsu Tadashi , McDaniel Anthony , Lany Stephan
Published: May 2022

We present a graph neural network modeling approach that fully automates the prediction of the DFT-relaxed vacancy formation enthalpy of any crystallographic site from its DFT-relaxed host structure. Applicable to arbitrary structures with an accuracy limited principally by the amount/diversity of the data on which it is trained, this model accelerates the screening of vacancy defects by many orders of magnitude by replacing the (up to 100s of) DFT supercell relaxations required for each symmetrically unique crystal site. It can thus be used off-the-shelf to rapidly screen 10,000s of crystal structures (which can contain millions of unique defects) from existing databases of DFT-relaxed crystal structures. We demonstrate the model's practical utility by high-throughput screening metal oxides from the Materials Project to identify high potential candidates for solar thermochemical water splitting. Ultimately, this modeling approach provides a significant screening and discovery capability for any application in which vacancy defects are the primary driver of a material's utility.
Paramagnetic NMR Shielding Tensors Based on Scalar Exact Two-Component and Spin-Orbit Perturbation Theory
Authors: Bruder Florian , Franzke Yannick J. , Weigend Florian
Published: May 2022

The temperature-dependent Fermi-contact and pseudocontact terms are important contributions to the paramagnetic NMR shielding tensor. Herein, we augment the scalar-relativistic (local) exact two-component (X2C) framework with spin-orbit perturbation theory including the screened nuclear spin-orbit correction for the EPR hyperfine coupling and g tensor to compute these temperature-dependent terms. The accuracy of this perturbative ansatz is assessed with the self-consistent spin-orbit two-component and four-component treatments serving as reference. This shows that the Fermi-contact and pseudocontact interaction is sufficiently described for paramagnetic NMR shifts, however, larger deviations are found for the EPR spectra and the principle components of the EPR properties of heavy elements. The impact of the perturbative treatment is further compared to that of the density functional approximation and the basis set.

Introduction. The article is devoted to the results of a study of the cutting resistance of road asphalt concrete in the process of removing worn coatings by the working bodies of milling machines. The relevance of the work is due to the emergence of new grades of asphalt concrete and new types of cutting elements, for which it is difficult to predict the loads on the working body when solving the problems of designing new and justifying the operating modes of existing machines.Purpose. To calculate the parameters of the working body of the road milling machine.Materials and methods. The experimental work was carried out by determining the horizontal and vertical components of the resistance force of cutting asphalt concrete. The research was carried out on a mechanical stand with a movable plate, using recording equipment. Four different grades of asphalt concrete were destroyed. A twofactor experiment was conducted for each brand of material. The horizontal and vertical components of the cutting resistance forces were determined depending on the chip cross-sectional area, the grade of asphalt concrete and the type of cutting element.Results. As a result of the experiment, data were obtained that make it possible to reasonably determine the loads on the working body of the road milling machine. It is proved that the dependence of the cutting resistance forces on the chip cross-sectional area of the cutting element has a nonlinear character. The data obtained allow to comprehensively answer questions concerning the justification of the parameters of road milling machines.Discussion and conclusion. The obtained data allow to develop a mathematical model of the asphalt concrete milling process which will make possible to determine not only the loads on the working body and the energy intensity of the process, but also to reasonably approach the placement of cutting elements on the drum, determine the rational range of equipment operating modes and solve the problems of choosing operating modes depending on the type of asphalt concrete.

O avanço das tecnologias móveis, associado à mobilidade crescente dos dispositivos, permitiu a incorporação do ambiente virtual a diversas atividades cotidianas, inclusive no âmbito da saúde, introduzindo conceitos como telemedicina, telessaúde, eHealth e mHealth. Além de apresentar esses novos conceitos, o presente artigo teve como objetivo discutir os avanços e os desafios das tecnologias móveis em saúde a partir de reflexões sobre desenvolvimento, aplicações, legislação e ética. Por seu caráter inovador, as tecnologias móveis em saúde envolvem muitos atores na jornada até o usuário final, focados na concepção, desenvolvimento técnico, regulação sanitária e elaboração de diretrizes clínicas, e têm despertado grande interesse para fins de monitoramento e cuidados em diferentes condições clínicas. Entretanto, na avaliação da efetividade e da segurança das tecnologias móveis em saúde, não se observa o mesmo rigor metodológico exigido para ensaios clínicos de medicamentos e outros produtos de saúde; ainda, o entusiasmo pela inovação se contrapõe às preocupações regulatórias e éticas relacionadas à proteção de dados, à privacidade, ao acesso aos dispositivos móveis e às disparidades tecnológicas e sociais. Apesar das possíveis limitações, as tecnologias móveis, assim como outros recursos da telessaúde, têm alcançado resultados promissores. A atenção digital em saúde tem grande potencial de expansão e representa uma oportunidade para que as práticas tradicionais de saúde sejam revisadas a partir da seleção e da incorporação das tecnologias móveis aos sistemas de saúde, sempre que sejam observados benefícios embasados nas melhores evidências.

This research aims to reveal the financial inclusion that occurs in zakat institutions within zakat distribution and empowerment program in Indonesia and Brunei Darussalam. This study will deliver zakat distribution and empowerment program held by zakat institutions in two countries and then analyze how have financial inclusion process happened to mustahiq in both institutions. The object of this research are the government zakat institution in two countries, namely Indonesia (BAZNAS) and Brunei Darussalam (BAKAZ). This study uses a qualitative method within multiple case strategy. Data collection in this study was carried out through in-depth interviews with several expert informants of BAZNAS and BAKAZ and also mustahiq of each institutions. This study shows that there is mustahiq financial inclusion process on empowerment program held by BAZNAS and BAKAZ by the distribution of zakat for consumption and production needs. Financial inclusion happened in zakat institutions are transferring zakat funds, financing mustahiq business within capital loan, and channeling to financial institutions, so that mustahiq can transform gradually to be bankable and have financial access to scale up their business

Предлагается расширение модели коэффициента интенсивности напряжений на длинные трещины полуэллиптической формы с учетом обобщения Мураками, ограниченного короткими трещинами. Методика позволяет с приемлемой эффективностью рассчитать коэффициент интенсивности напряжений путем использования новой поверхности, возникшей в результате распространения трещины. Предлагаемое расширение модели учитывает два фактора, которые непосредственно влияют на характер распространения указанного типа трещин, - преждевременное закрытие и воздействие нагрузок. Валидация новой модели проведена с использованием результатов усталостного поведения толстых пластин при трехточечном изгибе с тремя коэффициентами нагрузки. Расчет скорости распространения фронта трещины и количества циклов перехода от одного фронта к другому возможен путем адаптации формулы Пэриса к разработанной модели ΔK, которая является репрезентативной для всего фронта трещины, а не только для нескольких выбранных точек. Предложенная методика может рассматриваться как упрощенный метод оценки опасности полуэллиптических трещин, особенно для сосудов под давлением, и открывает новые перспективы использования поверхности трещины в исследованиях усталости материала.

In this work, an extension of the stress-intensity factor model to long semi-elliptic shaped cracks is proposed considering the generalizing of Murakami limited to short cracks. The latter allows the calculation of the stress intensity factor by using the new surfaces of the crack created by propagation with an acceptable efficiency. The extension we propose to take into account the effect of two factors which are directly influencing the propagation behaviour of this cracks type, the premature closure, and the load ratio. The validation of the new model was carried out using the fatigue results reported in literature on thick plates by three-point bending with three load ratios. The calculation of the propagation velocity of the crack front and the number of cycles of the transition from one front to another is possible by adapting the Paris law to the new model of ΔK, that is representative of the entire crack front and not only a few points generally chosen on the front and is considered as a characteristic. This methodology can provide engineers with a simplified method to evaluate the harmfulness of this type of cracks, especially in the case of pressure vessels. It can also open new perspectives on the use of a crack surface in fatigue studies.

This study aims to determine the role of institutions in achieving employee work optimization at the Dinas Ketahanan Pangan Kota Pekanbaru. Optimization is an action or process that makes something better and more effective. If optimization is associated with the role of institutions, then there are institutional norms that encourage the achievement of work optimization. This study used the Hardjanto indicators, namely equality, consensus orientation, participation, and responsiveness. The research method in this study is qualitative. The result shows that the Dinas Ketahanan Pangan Kota Pekanbaru encourages institutional role in running its organization. Leaders liven up certain norms such as giving every employee fair and equal rights and obligations following their duties and functions, prioritizing deliberation in the policy process, respecting active participation, and encouraging a responsive and serving work culture. Of the four indicators, the responsiveness dimension has not worked well, while the other three dimensions have been implemented properly.ABSTRAKPenelitian ini bertujuan untuk mengetahui peran kelembagaan dalam mencapai optimalisasi kerja pegawai pada Dinas Ketahanan Pangan Kota Pekanbaru. Optimalisasi adalah tindakan atau proses yang membuat sesuatu menjadi lebih baik dan lebih efektif. Jika optimalisasi dihubungkan dengan peran kelembagaan, maka ada norma-norma kelembagaan yang mendorong tercapainya optimalisasi kerja. Penelitian ini menggunakan indikator Hardjanto dimana peran kelembagaan ditentukan dari 4 dimensi yang melekat, yaitu equality, consensus orientation, participation, dan responsiveness. Metode penelitian dalam studi ini adalah kualitatif. Hasil penelitian yaitu Dinas Ketahanan Pangan Kota Pekanbaru menghidupkan peran kelembagaan yang kuat dalam menjalankan organisasinya.
