Optimization of Biogas Production from Potato Peels and Fish Waste using MATLAB
Authors: Ogur Eric
Published: June 2024

Optimizing biogas production from organic waste is crucial for sustainable energy and waste management. This study investigates the use of potato peels and fish waste as substrates for anaerobic digestion. By integrating mathematical modelling, experimental design, and computational simulations, the research enhances the understanding and optimization of the anaerobic digestion process. A mathematical model based on Monod kinetics and mass balance principles was developed to describe substrate utilization, biomass growth, and biogas production. This model incorporates variables such as substrate concentration, microbial biomass, and biogas production rate, while accounting for factors like temperature and pH. MATLAB was used to solve the equations and validate the model with experimental data. The experimental setup involved a continuous stirred-tank reactor (CSTR) with controlled operational parameters. A detailed experimental design ensured reliability, involving randomization, blocking, and control experiments. Data on substrate and biomass concentrations, volatile fatty acids, chemical oxygen demand, and total solids were collected and analysed. Results showed a strong linear relationship between actual and predicted biogas yields, with an R2 value of 0.99238, indicating high predictive accuracy. Analysis of variance (ANOVA) confirmed the significant impact of substrate composition, temperature, and pH on biogas production. A refined regression model highlighted the positive impact of higher temperatures and pH levels, while revealing a synergistic interaction between substrate composition and pH. Using Design of Experiments (DoE) and MATLAB optimization, the optimal conditions were found to be 72% potato peels, a temperature of 51°C, and a pH of 7.4, resulting in a predicted biogas production rate of 0.49 L/h. These findings highlight the potential for efficient resource utilization and biogas production. This study provides a comprehensive understanding of the anaerobic digestion process, aiding the development of sustainable biogas production strategies. The integration of mathematical modelling, experimental design, and computational simulations proves invaluable in optimizing biogas production from organic waste, supporting global renewable energy and waste management efforts. The insights gained pave the way for practical applications in industrial and municipal settings, fostering a transition towards a more sustainable future.

The high-density elements are harmful even in low quantities such as heavy trace metals; Arsenic, Copper, Cadmium, Lead, Mercury, and Chromium which are hazardous to the natural resources. They enter waterways by industrial operations, mining, urban runoff, agriculture, e-waste, and pesticides and cause cytotoxicity, neurotoxicity, organ damage, cancer, and weak bones. may remedy heavy metal pollution. Some promising methods that could reduce the heavy metal contamination of wastewater are membrane filtration, catalysts, ion exchange, biosorbent, and nanomaterial adsorption. In this study, Datura metel fruit peel biochar (DPB) infused with zinc oxide nanoparticle (ZnO-NP) is used as a nanocomposite for the remediation of Pb2+ and Cd2+ from synthetic wastewater. The best parameters for DPB and DPB-ZnO3 (3% infusion ratio of ZnO-NP) adsorption of Pb2+ and Cd2+ ions in synthetic wastewater were 3% ZnO infusion ratio, 6.75 solution pH, 65 minutes contact time, and 82 mg/l starting heavy metal concentration. Both DPB and DPB-ZnO biosorbents adsorb Pb2+ better than Cd2+ under the indicated conditions. For Cd2+ adsorption, DPB and DPB-ZnO had the greatest capacities of 27.56 and 48.27 mg/g, respectively. DPB and DPB-ZnO had maximal Pb2+ adsorption capabilities of 25.17 and 49.38 mg/g. The current study represents the adsorption capability of the nanocomposite concludes that Pb2+ and Cd2+ can be efficiently remediated from heavy metal contaminated wastewater that gives substantial advantages in terms of environmental protection and human health.

Published: June 2024

Background Uganda experiences high maternal mortality ratios, with suboptimal utilization of maternal health services like antenatal care (ANC), especially in rural areas. Community Health Workers (CHWs), known as Village Health Teams (VHTs), have shown the potential to enhance maternal and child health (MCH) outcomes in Uganda by educating pregnant women in the community. However, their training models need to be refined to boost their performance.Objective We evaluated the effectiveness of a contextually tailored educational intervention delivered by VHTs on the knowledge, attitudes, and antenatal care attendance of pregnant women in Eastern Uganda.Methods We performed a quasi-experimental study using a pre-post-intervention evaluation conducted over six months in Eastern Uganda. We included pregnant women in their first trimester who consented to participate and excluded those in later trimesters. We performed multistage sampling with villages randomly selected and participants enrolled by trained VHTs. The VHTs were trained using a Maternal Newborn Child Health curriculum developed by a multidisciplinary team of healthcare professionals. The VHTs delivered educational sessions to the participants during home visits throughout their pregnancy. Data was collected on pregnant women's knowledge, attitudes, and antenatal care attendance before and after the intervention. A score of ≥ 75% was considered sufficient knowledge. The Chi-square test was used to test the difference in the proportional change in knowledge and attitude of pregnant women. A paired two-sample t-test assessed changes in ANC attendance pre- and post-intervention. A p < 0.05 was considered statistically significant.Results 228 participants were included, with a mean age of 27 ± 5.90 years and gravidity of 2.92 ± 1.47. There was a significant improvement in participant proportions with sufficient MCH knowledge (post-intervention: 80.3% versus pre-intervention: 19.6%, p < 0.001). Attitudes towards healthy MCH behaviors improved post-intervention; 98.7% of women agreed that attending eight or more ANC visits is crucial, compared to 88.1% before intervention (p < 0.001). Additionally, 99.6% of participants recognized a health facility as the best place for ANC post-intervention, compared to 89.9% pre-intervention (p < 0.001). The average number of ANC visits significantly increased from 1.22 to 6.38 (p < 0.001).Conclusion Contextually tailored education delivered by trained CHWS significantly improved maternal health knowledge, attitudes, and ANC attendance among pregnant women in rural Uganda.

Published: June 2024

This study assessed the quality of water for drinking and irrigation purposes on the southern slopes of Mt. Kilimanjaro during the dry season under low flow conditions. Fifty-one samples covering 8 different water types were collected in a snapshot sampling campaign over 10 days in February 2023. First, physical, chemical and biological parameters were analysed and compared with Tanzanian and international requirements for drinking and irrigation water quality. The samples were then ranked according to their suitability for drinking and/or irrigation using water quality indices (WQI). All drinking water quality parameters except for E. coli and turbidity were within the reference standards. A generalized problem of faecal contamination was found in the study area, including in domestic water, which highlights the need to identify sources of contamination and remediate before distribution. The drinking water quality index (DWQI) classified 77% of the samples as unsuitable, 4% as poor or very poor and 19% as good or excellent for drinking. Irrigation water quality parameters were within the guidelines of restriction of use except for pH in 5 samples. All samples were classified as safe for irrigation according to the irrigation water quality index (IWQI). However, five other irrigation indices (Kelley’s Index, Soluble Sodium Percentage, Permeability Index, Residual Sodium Bicarbonate and Magnesium Ratio) showed potential problems with excess of sodium and magnesium. A combination of indices is recommended for assessing water quality for irrigation use.

Authors: Ding Yuan , Zheng Hengyi , Jin Fuming , Chen Dongming , Huang Xinyu
Published: June 2024

This paper proposes an innovative cellular automata model based on the Harris Hawk Optimization (HHO) algorithm. HHO is an intelligent optimization algorithm inspired by the cooperative hunting behavior of Harris's hawks, demonstrating excellent optimization efficiency in spatial searches. Combining the HHO algorithm with the CA model, we establish the HHO-CA model for simulating urban growth in Guangzhou, China. The simulation achieves a total accuracy of 91.95%, an accuracy of urban cells of 82.43%, and a Kappa coefficient of 0.7441, all superior to the Null model. Furthermore, comparing the HHO-CA model with other representative CA models, the HHO-CA model outperforms in total accuracy, accuracy of urban cells, and Kappa coefficient, showcasing significant advantages in using the HHO algorithm to mine transition rules during the simulation of urban growth processes.

Published: June 2024

São apresentados dois novos registros de aves para o estado de Santa Catarina, na região da Lagoa do Mirim, no município de Imbituba, e no Parque Municipal das Dunas da Lagoa da Conceição, em Florianópolis. O primeiro é o registro fotográfico de Cinclodes fuscus (Passeriformes: Furnariidae), que foi relatado para o estado, em 1996, apenas por observação visual, sem documentação. É espécie monotípica e comum no extremo Sul do Brasil, ocorrendo em campos e pastagens do sul da América do Sul, realizando movimentos migratórios para o Norte no inverno. O segundo registro é de Sporophila ruficollis (Passeriformes: Thraupidae), espécie distribuída no sudoeste da América do Sul, também espécie monotípica, com sua população em declínio mundialmente e ameaçada no Brasil, onde inverna em áreas abertas do centro-sul do país. Esses registros foram realizados em áreas úmidas, em um dos grandes complexos lagunares de Santa Catarina, próximo a cultivos de arroz, e no Parque Municipal das Dunas da Lagoa da Conceição, por meio da observação de aves. Foram documentados por meio da ciência cidadã, pesquisa bibliográfica e documental. Infere-se que os indivíduos visualizados são possivelmente vagantes, de partes das populações que migram na época do ano em que foram registrados.
Occurrence of Cteisa hirta Solier, 1835 (Tenebrionidae, Alleculinae) in an abandoned nest of a social wasp (Vespidae: Polistinae)
Authors: De Castro Jacques Gabriel , Carvalho Tavares Maryá Cristina , Coelho Francisco Sheliane Cristina
Published: June 2024

Abandoned nests of social wasps (Vespidae: Polistinae) are often occupied by other arthropods such as ants, spiders, termites, bees, and solitary wasps. However, there are no records of any species of Coleoptera occupying these structures. Therefore, this work aims to report the occurrence of a beetle in an abandoned nest of a social wasp. The presence of the beetle Cteisa hirta (Tenebrionidae, Alleculinae) was observed in a nest of the genus Polistes, at IFMG - Campus Bambuí on March 9, 2023. As only one nest was recorded with the presence of a beetle, it can be suggested that this occupation is casual, but further studies need to be carried out to confirm that the use of abandoned nests by Tenebrionidae, or another family of Coleoptera, is not frequent.

Motivado pela necessidade de exploração de alternativas sustentáveis para materiais de construção, este estudo pioneiro investigou a viabilidade do uso do coproduto de alumina na produção de argamassa, uma área pouco explorada na literatura. Apesar da natureza alcalina do coproduto, sua adição às argamassas demonstrou fornecer resistência adequada e impacto ambiental reduzido. A introdução gradual do coproduto resultou em uma ligeira redução na resistência à compressão, mas de acordo com padrões aceitáveis. As análises químicas revelaram aumentos significativos nos teores de óxidos de ferro, sódio e alumina nas amostras, conferindo características distintivas às argamassas. Ambientalmente, as amostras foram classificadas como classe II-A não inerte, indicando menor impacto ecológico. Os artefatos produzidos com as amostras A2 e A3 apresentaram boa resistência à compressão e acabamento avermelhado, em virtude do óxido de ferro. O trabalho oferece uma perspectiva sustentável e inovadora para a reutilização de resíduos industriais, com benefícios potenciais tanto para a indústria quanto para o meio ambiente.

Published: June 2024

Esse ensaio aborda a complexidade da integração das Lutas/Artes Marciais (L/AM) na Educação Física escolar enquanto unidade temática na busca de analisar a posição muitas vezes contraditórias dessas práticas no currículo da área. De forma específica, investiga-se as tensões entre a rejeição histórica das L/AM, as abordagens de ensino tradicionais, o uso de jogos de oposição e a necessidade de uma pedagogia mais crítica e problematizadora nas aulas de Educação Física. Com uma metodologia de ensaio teórico, o trabalho se aprofunda na análise de argumentos estabelecidos à negação de tal manifestação na escola, contrastando-os com a realidade prática e engajando-se em um diálogo crítico com literatura especializada e com aporte da pedagogia crítica. Nesse contexto, destaca-se a relevância das L/AM não apenas pelo seu valor corporal e de movimento, mas em razão do seu rico substrato cultural e histórico. Sendo assim, discutimos os desafios e potencialidades da inclusão das L/AM na Educação Física escolar, enfatizando a necessidade de superar preconceitos e mal-entendidos associados a essas práticas. O texto conclui que as L/AM devem ser tematizadas nas aulas de Educação Física escolar como parte da cultura corporal, ressaltando a importância de abordagens pedagógicas que respeitem sua complexidade e contribuam à formação integral dos(as) estudantes.

Este estudo teve por objetivo descrever os embates de Luta Marajoara que compõem a festa de corte dos mastros da festividade de São Sebastião, realizada no município de Cachoeira do Arari, ilha de Marajó, Norte do Brasil. Metodologicamente, adotou-se abordagem qualitativa, a Etnometodologia como método, bem como a observação participante, o registro fotográfico, o caderno e o diário de campo como instrumentos para a reunião dos dados. Como resultado, notou-se que, na festa de corte dos mastros, a Luta Marajoara não possui um único espaço delimitado para sua prática. Seu espaço é o capim, a pissarra, a areia. Os lutadores, por vezes, lutam após ingerir bebida alcoólica e os embates ocorrem ao som das folias dedicadas a São Sebastião, carimbó ou músicas carnavalescas. Conclui-se que a festa de corte dos mastros é um momento no qual a Luta Marajoara se faz presente, com performances que a atravessam em diversos momentos e se entrelaçam com outros elementos festivos.

Authors: Sobolev Vladimir , Muminova Madina , Zhukova Olga , Denisova Elena , Soboleva Anna , Potekaev Nikolay , Korsunskaya Irina , Mezentsev Alexandre
Published: June 2024

Background:

Restructuring of dermal microcapillaries is one of the
hallmarks of plaque psoriasis. To control the proliferation of vascular endothelial cells,
vascular endothelial growth factor (VEGF) promotes the remodeling of the existing
blood vessels and angiogenesis.

Objective:

This study aimed to explain the lowering protein and mRNA levels of VEGF
in lesional skin of patients with severe psoriasis (the Psoriasis Area and Severity
Index, PASI > 25).

Methods:

Using the method of qPCR, we assessed the expression of VEGF mRNA in
lesional and nonlesional psoriatic skin. Using ELISA, we also compared the levels of
VEGF in skin homogenates of psoriasis patients and healthy volunteers.

Results:

We found that the exacerbation of psoriasis induced VEGF on mRNA and
protein levels 12 and 20 times, respectively. We also confirmed a strong correlation
between VEGF and PASI score in patients with PASI < 25. In addition, we showed that
several factors, namely HGF, HNRPD, and sFLT1 interfere with the biosynthesis of
VEGF in skin lesions of patients with PASI > 25%.

Conclusion:

Thus, using VEGF as a biomarker to monitor the disease shall be done
cautiously in patients with severe psoriasis.

Authors: Shokri Khadijeh , Farrokhi Naser , Ahmadikhah Asadollah , Safaeizade Mahdi , Mousavi Amir
Published: June 2024

Background:

Gene expression is regulated in a spatiotemporal manner, and the roles of
microProteins (MiPs) in this concept have started to become clear in plants.

Methods:

Here, a microarray data analysis was carried out to decipher the spatiotemporal role of
MiPs in embryo development. The guilt-by-association method was used to determine the corresponding
regulatory factors.

Results:

Module network analyses and protein-protein interaction (PPI) assays suggested 13 modules
for embryo development in the Arabidopsis model plant. Various biological processes such as
metabolite biosynthesis, hormone transition and regulation, fatty acid and storage protein biosynthesis,
and photosynthesis-related processes were prevalent. Different transcription factors (TFs) at different
stages of embryo development were found and reviewed. Furthermore, 106 putative MiPs
were identified that might be involved in the regulation of embryo development. Candidate hub
MiPs (15) at embryo developmental stages were identified by PPI network analysis and their putative
regulatory roles were discussed. Previously reported MiPs, AT1G14760 (KNOX), AT5G39860
(PRE1), and AT2G46410 (CPC), were noted to be present in modules M3 and M8.

Conclusion:

Molecular comprehension of regulatory factors including MiPs and TFs during embryo
development allows targeted breeding of the corresponding traits and genome-based engineering of
value-added new varieties.
Zirconia Cementation: A Systematic Review of the Most Currently Used Protocols
Authors: Batista Adriana , Palacios Nayeli , Ricardo Alvarado Jiménez Omar
Published: June 2024

Objective

A systematic review of the existing literature was conducted and in vitro studies from 2019 to 2023 were analyzed on Zirconia's most resistant cementation protocol.

Methods

A systematic review of studies on the bond strength between zirconia and resin cement was carried out using different surface treatment protocols. The search was performed in two electronic databases, PubMed and Cochrane.

Results

Electronic searches yielded 1225 non-duplicated articles (Fig. 1), of which 388 were chosen after screening the titles and abstracts. After examining the full texts of these articles, a further 340 were excluded. There remained 48 studies to which the selection by inclusion and exclusion criteria was applied, eliminating 31 articles, of which 17 were finally included for the qualitative study.

Conclusion

Under the limitations of the present systematic review, it can be concluded that treating Zirconia with a combination of surface modifying agents, both mechanical and chemical, substantially improves its adhesive ability with resin cement. Aluminum oxide sandblasting, hydrofluoric acid etching, tribochemical silica coating, laser, and etching with a combination of acids in the Zircos E system are micromechanical treatments that improve the bond strength between zirconia and resin cements. MDP silane agent is an effective chemical treatment to improve the bond strength between zirconia and resin cements. Coating exclusively with a silica layer does not improve the bond strength between zirconia and resin cement.
Research on Optimization of Nonlinear Extended State Observer for the
Upper-Limb Rehabilitation Robot Controller
Authors: Zhang Peng , Liu Luyu , Nan FangHao , Wang Peng
Published: June 2024

Background:

In recent years, patents have shown that upper-limb rehabilitation robots
play a significant role in home-based rehabilitation training for stroke hemiplegia patients. Changes
in muscle tension during the flaccid paralysis phase cause the rehabilitation robot to deviate from
the predetermined motion trajectory. This poses a challenge to the mathematical modeling of the
rehabilitation robot and the design of the nonlinear extended state observer (NESO).

Objective:

To address the problem of trajectory tracking errors caused by the rehabilitation robot
when the patient's muscle tension changes, a method based on optimizing the nonlinear function
within the NESO is proposed.

Methods:

First, a mathematical model of the upper-limb rehabilitation robot is established to obtain
the dynamic relationship between the robot's velocity and the input voltage. Second, the nonlinear
function of NESO is optimized by adjusting the gain values of the sine and tangent functions to effectively estimate the muscle tension and reduce the problem of accumulative error due to changes
in muscle tension. Finally, comparative simulations of trajectory tracking including the optimized
nonlinear function as well as the sine, tangent and power functions are performed on the MATLAB
platform.

Results:

NESO is constructed to estimate changes in muscle tension based on sine, tangent, and
power functions, as well as optimized nonlinear functions. The equivalent gain values of each function and the muscle tension estimation curves of NESO are compared. The simulation results show
that the equivalent gain value of the optimized nonlinear function acting in NESO is increased to
more than 8 and the convergence time is reduced by 11.9% accordingly. This conclusion is validated by simulations and practical tests.

Conclusion:

The optimized nonlinear function shortens the estimation time of the NESO for
changes in muscle tension, which can provide a reference value for the design of observers for upper-limb rehabilitation robots of patients in the flaccid paralysis stage.
Things Fall Apart de Chinua Achebe — texto orgulhosamente negro
Authors: Pinto Cristina Ferreira
Published: June 2024

Chinua Achebe, a Nigerian author, has been considered by critics as one of the most impor-tant founders of African literature, in reaction to the literature that until then had been produced on Africa. In the sequence of the most diverse colonial literary texts and the arguments that validated colonialism in Africa, always in a dimension of affirmation of white superiority and black savagery, and in which any value, history, or notion of culture was denied to African peoples, Achebe begins a mission to show the western world that pre-colonial Igbo culture had beauty, philosophy, dignity and viable social, political and judicial structures, and that it was by no means an example of the «blank slate» that many Europeans wanted people to believe. In this sense, Achebe publishes his first novel, Things Fall Apart, still in a colonial context (1958), to make his culture known, realistically and based on internal knowledge, in a counterpoint to this prejudiced and racist European devaluation.
A cor dos textos: possíveis indícios intertextuais de categorização racial
Authors: Lima Rafahel Jean Parintins
Published: June 2024

This study investigates intertextual clues of the role of racial categorisation in the (dis)alignment of the meaning attributed by opinion articles’ authors to the hashtag #SomosTodos-Macacos. The hashtag #SomosTodosMacacos was posted on the Instagram social network by Neymar Júnior on April 27, 2014, in response to a racist incident that occurred on the same day against his then-teammate Daniel Alves during a football match. The study is grounded in socio--cognitivist studies of Textual Linguistics and a socio-historical-cultural perspective on racial categorisation. The methodology involved analysing intertextual features in 10 opinion articles published between April 27 and May 3, 2014, regarding #SomosTodosMacacos. The study’s findings suggest that black authors tend to adopt a critical stance toward the implicitly racist meaning attributed to the #SomosTodosMacacos through intertextual forms of disalignment and other textual constructions.

Authors: Espírito Santo Silvia Maria do , Leonor Cláudia , Lotumolo Jr. José
Published: June 2024

The paper analyses the performance of I had too much coffee, by Ismael Ivo, directed by the German Ralf Schmerberg in 2002. From the audiovisual document, the human values expressed through the dancer’s body language bring forth the concepts of «colonial» and «decolonial». The audiovisual is rich in references to body language and can be interpreted through the concept of intrigue within Paul Ricœur’s narrative framework. The research examines and identifies the social meanings of coffee cultural memory by understanding virtual narratives in times of dystopia and the meanings that emerge from the concept of colonialism. The study utilises the selection of audiovi-sual material and describes the elements of document analysis based on social theory criticism, enabling us to confront contemporary impressions and the chosen memories of the past. The analy-sis yields an understanding that goes beyond the immediate perceptions enabled by entertainment, thus integrating the operative arguments of social reality.

Cold-formed steel is being used as a viable substitute for traditional steel and building materials due to its performance, affordability, convenience, lightweight, and environmental friendliness. The major purpose of this current research is for a reaction to force-deformation at the connection level to be delivered, which is proper for typical cold-formed steel (CFS) screwed beam-column assembly CFS C-section, and to show the influence of the behavior of CFS under bending test. An inner plate, double angle plate, and self-drilling screws are used by a basic beam-column frame idealized CFS to join the beam-column. Fixed support was implemented at the column base, whereas the beam end had free support. A 0.75 mm cold-formed steel C-section with 80mm height and 30mm width was utilized in this study and assembled into an "I" and "box" configuration. 3d and 4d were used to compute screw spacing for self-drilling screws with 4 mm heads and 2 mm bodies. The first type was each angle plate (top and seat angle) screwed with eight screws, whereas the second involves four screws. The CFS section’s thinness led to the use of screw connections, which are essential to their ability to withstand connection failures, to anticipate the failure mode of the connection segment. Numerical simulation by ABAQUS Student Edition and analytical studies have been conducted by AS/NZS 4600:2018 to investigate the capacity of CFS under bending. Quantity and the arrangement of the screws determine the displacement ductility with tighter spacing enhancing performance and reinforcing global and local buckling resistance.

Delays in construction projects are common and persistent. Frequent disputes also make work time inefficient and result in significant cost increases. Therefore, it is necessary to study or investigate events that are useful as a solution to delay claims and have the potential to be used in litigation. This research has been conducted to maximize reliable data sources. The Source Validation Protocol guides the process for ensuring the validity of the source data based on the Forensic Schedule Analysis methodology. According to the Critical Path Method (CPM) schedule analysis, the construction time of the Rusunawa Building (Rent Simple Flat) of the Health Polytechnic of the Ministry of Health Yogyakarta is 73.2 weeks or 511 calendar days. The 2 data source validation protocols, including Validation of Baseline Schedule Selection, Validation and Rectification, and Validation of As-Built Schedule Sources, Reconstruction, and Validation, greatly influenced the project delays.
Seismic Capacity of Reinforced Concrete Eccentric Braced Frame (EBF) With Vertical Link Using 20% GGBFS

EBF-V bracing is highly attractive due to its good seismic performance in high seismic zones. Vertical link beams as a component are capable of high elastic displacement and ductility to absorb lateral forces through shear-bending collapse mechanisms. However, the lateral load capacity of the bracing has to be sacrificed as it tends to decrease. The present study focuses on the capacity and lateral behavior of reinforced concrete eccentrically braced frame (EBF) with vertical link beam and tighter reinforcement spacing in the link beam in combination with GGBFS. GGBFS at 20% can improve the mechanical properties by reducing the pore number of the concrete due to the smaller particle size of OPC.This study uses CBF-V as a control to investigate the seismic behavior of tightly spaced transverse reinforcement (75 mm) in EBFs’s vertical link beam with eccentricities of 15 cm and 25 cm. In addition, the role of GGBFS was also observed through the displacement and ductility of the frame. As a result, the CBF has the highest plasticity. However, the tight reinforcement spacing of the vertical link beam in the EBF-V-15 results in the highest restraint, resulting in excellent stiffness and ductility through earthquake absorption with a shear collapse mechanism. In addition, GGBFS also plays a role in improving the collapse mechanism, which is characterized by large elastic displacement and high ductility.

Objective: to study the frequency and structure of traumatic brain injury in the pre-ovoid, covid and post-ovoid periods in Rostov-on-Don.

Materials and methods: to study the frequency and structure of traumatic brain injury in three years from 2019 to 2021 (in the pre-ovoid, covid and post-ovoid periods) according to the neurosurgical department and the department of combined trauma of the Emergency Medical Hospital No. 2 in Rostov-on-Don. Data processing using the IBM SPSS Statictic program version 26.0 using the χ2-Pearson criterion, in pairwise a posteriori comparative analysis, the χ2-Pearson criterion with Yates correction and likelihood correction were used. If the significance level is p<0.05, the differences are statistically significant.

Results: in the pre-crisis period (2019), household trauma prevailed, the total number of hospitalized with TBI was 1,322. Of these, concussions accounted for 71%, brain contusions accounted for 28%, diffuse brain injury — 1%, street injury — 6.9%, transport injury — 6.81% and intentional injury — 24.1%. In the covid period (2020), the total number of patients admitted to the department decreased by 24%. The structure of the injury remained unchanged (concussions in 70% of cases, brain contusions in 28%, diffuse brain injury in 2%). In 2021 (completion of covid restrictions), the number of inpatient patients with TBI remained reduced (by 23%), the ratio of concussions, bruises, diffuse brain injuries remained the same.

Conclusions: during the period of social isolation, there was a decrease in the number of hospitalized with TBI, which coincides with global indicators. The end of the restrictions associated with the pandemic is also characterized by a decrease in the number of patients admitted to the hospital with TBI. At the same time, a decrease in the ratio of the number of hospitalizations to the total number of deaths from head injury in 2019 and 2020 should be taken into account. from 19.83 to 14.98 in the Rostov region (according to the Federal State Statistics Service on the number of deaths from head injuries in 2019-2020), which reflects the level of accessibility of medical care. There was also a significant decrease in household, street, transport, school, sports and intentional types of TBI (p<0.05), while occupational injuries and trauma, the circumstances of which are unknown, did not significantly differ from the pre-pandemic indicators. Taking into account these results will improve the organization of emergency and emergency medical care for patients with TBI.

Menurut Peraturan Presiden Nomor 82 Tahun 2018 tentang Jaminan Kesehatan, pemberi kerja wajib mendaftarkan diri dan pekerjanya sebagai peserta JKN-KIS. Sayangnya, belum semua badan usaha mendaftar, terutama usaha mikro dan kecil, padahal jumlah badan usaha setiap waktunya terus bertambah. Terdapat 68% badan usaha mikro dan kecil potensial di Kabupaten Jombang yang belum terdaftar JKN-KIS. Tujuan penelitian ini adalah menganalisis partisipasi badan usaha mikro dan kecil dalam Program JKN-KIS di Kabupaten Jombang. Penelitian kualitatif dengan pendekatan deskriptif melalui wawancara. Hasil penelitian menggunakan Teori Perilaku menurut L. Green, menunjukkan bahwa badan usaha yang sudah mendaftar memiliki pengetahuan yang baik dan sikap positif terhadap Program JKN-KIS, serta pernah mendapatkan promosi langsung dari BPJS Kesehatan. Risiko kesehatan tidak mempengaruhi keputusan mendaftar. Badan usaha yang belum mendaftar cenderung mampu membayar premi, namun kemauan membayar rendah. Kebijakan wajib berpartisipasi dan pemberian sanksi dianggap memberatkan bagi badan usaha yang belum mendaftar.

Dalam rangka meningkatkan efektivitas dan optimalisasi proses verifikasi klaim, BPJS Kesehatan membentuk sistem verifikasi klaim digital yang disingkat VEDIKA. Sejak diimplementasikannya sistem Vedika pada tahun 2018, terdapat peningkatan jumlah klaim yang dipending setelah implementasi Vedika di RSUD dr. H. Jusuf SK. Sampai saat ini masih belum ada evaluasi mengenai implementasi Vedika yang telah berjalan lebih dari 5 tahun, baik dari pihak RSUD dr. H. Jusuf SK maupun dari pihak BPJS Kesehatan Cabang Tarakan. Penelitian ini merupakan penelitian kualitatif dengan desain Studi Kasus. Data primer diperoleh dari wawancara mendalam. Data sekunder berupa telaah dokumen pendukung. Dalam pelaksanaan Vedika di RSUD dr. H Jusuf SK Kota Tarakan tahun 2022 terdapat permasalahan klaim yang menyebabkan klaim tidak dibayarkan. Faktor penyebab permasalahan klaim yang paling sering ditemukan adalah faktor verifikator, aplikasi Vedika dan kelengkapan dokumen klaim yang diajukan. Temuan ini dapat menjadi masukan untuk BPJS Kesehatan agar bisa menyeragamkan cara verifikasi yang dilakukan oleh masing-masing verifikator agar hasil verifikasi tidak jauh berbeda. BPJS Kesehatan juga dituntut untuk memperbaiki aplikasi agar permasalahan dalam penerapan Vedika bisa berkurang. Temuan ini juga menjadi masukan bagi RS untuk menyusun dan mengembangkan rekam medis elektronik untuk meminimalisir permasalahan klaim yang disebabkan oleh rekam medis. Dalam penerapan Vedika di RSUD dr. H Jusuf SK Kota Tarakan tahun 2022, ditemukan bahwa masih terdapat klaim-klaim yang ditunda pembayarannya yang disebabkan oleh adanya kasus readmisi, ketidaksesuaian kode diagnosa dan prosedur serta kasus yang masuk dalam penjaminan pihak lain. Selain itu Verifikator BPJS Kesehatan memiliki persepsi yang berbeda-beda terkait proses verifikasi klaim, sehingga hasil verifikasi akan berbeda pada masing-masing verifikator.

Published: June 2024

Pemerintah Indonesia telah menetapkan Perpres Nomor 72 Tahun 2021 sebagai landasan percepatan penurunan stunting di tingkat nasional, yang diikuti dengan RAN PASTI sebagai panduan di tingkat daerah.Akan tetapi, keberagaman kondisi daerah di Indonesia menghasilkan prevalensi stunting yang bervariasi sehingga komitmen pemerintah daerah menjadi kunci utama percepatan penurunan stunting. Namun, masih terdapat implementasi kebijakan stunting di daerah yang belum terlaksana dengan baik. Kabupaten Bulungan berhasil melaksanakan penurunan prevalensi stunting sebesar 7,68% dari tahun 2022 sehingga dapat dijadikan acuan terkait identifikasi praktik baik kebijakan di tingkat daerah. Penelitian ini bertujuan untuk mengidentifikasi keselarasan antara kebijakan nasional dan daerah dalam mengoptimalkan sumber daya untuk mengatasi stunting secara spesifik di tingkat daerah. Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus yang dianalisis menggunakan Teori Segitiga Kebijakan dari Walt dan Gilson melalui hasil studi dokumen, yakni menyandingkan substansi kebijakan nasional dengan kebijakan yang ada di Kabupaten Bulungan. Dokumen kebijakan daerah diperoleh melalui Bappeda Litbang setempat. Kemudian, hasilnya ditriangulasi melalui wawancara mendalam semi terstruktur dengan Kabid Kesmas Dinkes Kabupaten Bulungan. Hasil penelitian menunjukkan bahwa kebijakan yang diimplementasikan oleh Kabupaten Bulungan telah melibatkan lintas sektor dan berbagai aktor yang berbasis pentahelix, serta telah terkoordinasi dengan pemerintah pusat dengan baik. Strategi yang diterapkan bersifat berkelanjutan dan telah terintegrasi dengan program kesehatan nasional yang ada. Kebijakan daerah yang ditetapkan telah mengacu pada kelima pilar strategi nasional dalam Perpres Nomor 72 Tahun 2021. Terdapat juga SK TPPS guna mengatur mekanisme tata kerja TPPS di Kabupaten Bulungan yang telah mengacu pada RAN PASTI. Namun, terdapat beberapa hambatan, seperti kondisi pandemi covid-19, keterbatasan tenaga kesehatan, infrastruktur, dan fasilitas layanan kesehatan, serta persepsi masyarakat yang salah tentang stunting. Meskipun demikian, implementasi kebijakan Kabupaten Bulungan dinilai sudah selaras dengan kebijakan nasional.
