Authors: Tjandraningsih Dewi
Published: May 2024

The notaries who are suspected of committing acts of malpractice in their official duties, either intentionally or through negligence and violating Law No. 2 of 2014 concerning the Position of Notaries, can result in losses for the parties and can complain to the Notary Honorary Council and the police. This research aims to determine and analyze the authority of notaries in making authentic deeds, and legal certainty for the parties in an authentic deed. The research method uses normative legal research with a legislative approach that uses legal sources with library methods which are then analyzed to obtain a conclusion. The results and conclusions of the research are that a Notary is a public official who has the authority to make an authentic deed based on attribution or Law No. 2 of 2014, apart from that, authentic deeds are required by statutory regulations in order to create legal certainty, order and legal protection, so that the meaning of legal certainty will be properly actualized if the parties understand what is the purpose of the deed.

ResumoObjetivou-se, com esse estudo, analisar o perfil de resistência antimicrobiana e a capacidade de formação de biofilme de Enterococcus spp. isolados de queijo de coalho. Foram analisadas 36 amostras de queijo de coalho confeccionado com leite pasteurizado, comercializados em hipermercados da cidade do Recife-PE. Após isolamento e identificação por meio da técnica de coloração de Gram, do VITEK2® e testes bioquímicos, observou-se 36 isolados de Enterococcus spp., sendo 44,4% (16/36) Enterococcus faecalis, 44,4% (16/36) Enterococcus faeciume 11,2% (4/36) Enterococcus durans. Destes, 22,2% (8/36) apresentaram resistência à eritromicina, 25% (9/36) à nitrofurantoína, 22,2% (8/36) à tetraciclina e 2,7% (1/36) à vancomicina. Observou-se também que 22,2% (8/36) foram classificados como moderados formadores de biofilme e 77,8% (28/36) como fracos formadores. A ocorrência de cepas de Enterococcus spp. resistentes a antimicrobianos e formadoras de biofilme nas amostras de queijo de coalho avaliadas podem representar um risco à saúde pública, já que estes microrganismos são considerados emergentes e estão cada vez mais relacionados a casos de infecção hospitalar. Além disso, o monitoramento da resistência a antimicrobianos sintéticos mostra ser importante no controle de cepas de Enterococcus spp. resistentes às drogas disponíveis no mercado, que representam um dos maiores problemas de saúde pública mundial.

Published: May 2024

A insuficiência do ligamento cruzado cranial (ILCr Cra) completa ou parcial, resulta na perda de estabilização da articulação do joelho, sendo esta uma das principais causas de claudicação do membro pélvico, devido principalmente à dor intensa causada. Ainda, a insuficiência do ligamento cruzado cranial é uma afecção de casuística considerável em cães cuja causa é considerada multifatorial, sem predisposição sexual, com maior prevalência em cães de grande porte e obesos. Além do distúrbio clínico, o rompimento do ligamento cruzado cranial (LCCr) pode levar a complicações que incluem inflamação da membrana sinovial, osteoartrites, lesão do menisco e da doença articular degenerativa. O diagnóstico é realizado através do teste de gaveta cranial e compressão tibial, além de confirmação radiográfica. Uma das técnicas cirúrgicas para correção do rompimento do LCCr é a osteotomia de nivelamento do platô tibial (TPLO), que tem como objetivo morfofuncional de alterar a angulação anatômica através da osteotomia, rotação e estabilização da porção proximal da tíbia. A alteração da biomecânica restringe a ativação da articulação, fazendo com que ocorra a neutralização dinâmica do estímulo tibial cranial. Diante dos dados, o trabalho tem como objetivo apresentar uma TPLO realizada em uma cadela, SRD (sem raça definida), de nove anos, com resultado efetivo sem apresentação de complicações pós-operatórias.

Published: May 2024

O megaesôfago é uma enfermidade ocasionada pela hipomotilidade e dilatação esofágica parcial ou total, podendo ser congênito ou adquirido e subdivididos em primário, secundário, ou idiopático. Na forma congênita a patogenia não está totalmente esclarecida, mas, a sintomatologia inicia-se após o desmame e o filhote da ninhada apresenta subdesenvolvimento. O principal sinal clínico desta doença é a regurgitação após a ingestão de alimento e de água. O diagnóstico definitivo baseia-se no histórico, exame clínico e exames complementares de imagem. O tratamento é conservador, sendo necessário mudar o manejo alimentar e tratar as complicações que podem ser ocasionadas. Além disso, os cães mais acometidos são os médio a grande porte. Sendo assim, o objetivo deste trabalho é relatar um caso de um megaesôfago congênito em cão da raça Pinscher, filhote, com histórico de regurgitação desde o desmame, apetite voraz e retardo no desenvolvimento. Após o diagnóstico através de radiografia simples e contrastada foi iniciado o manejo alimentar e o paciente demonstrou melhora clínica.

Published: May 2024

O jabuti-piranga (Chelonoidis carbonaria), espécie de quelônio, apresenta particularidades anatômicas e fisiológicas que tornam a anestesia um procedimento desafiador. Somado a isso, existem poucos relatos de casos e de protocolos anestésicos seguros a serem seguidos para esses pacientes. O presente artigo teve como objetivo relatar as técnicas e procedimentos anestésicos empregados em um exemplar de jabuti-piranga, pesando 1,71 kg, submetido a celiotomia para retirada de corpo estranho. O paciente apresentava inquieto e com sinais de dor, como vocalização e exposição de pênis há 6 meses. Na anamnese foi observado presença de secreção nasal e ruído respiratório, casco disforme e lesões superficiais. Pelo exame radiográfico foi evidenciada uma estrutura afilada radiopaca, medindo 3,3 cm de comprimento de permeio, condizente com formato de um prego. Diante do quadro, optou-se por tratamento cirúrgico. Como medicação pré-anestésica, fez-se o uso de metadona (0,2 mg/kg; IM) e midazolam (0,5 mg/kg; IM) e administração de propofol (7 mg/kg IV). Após relaxamento muscular, o animal foi intubado com tubo endotraqueal número 2,0 (sem cuff) e infusão contínua de propofol (0,05-0,6 mg/kg/minuto). Para analgesia foi realizado o bloqueio local com a técnica splash block em cavidade abdominal com bupivacaina 0,5% sem vasocontritor (0,7 mL) após incisão cirúrgica. Os parâmetros fisiológicos monitorados, como frequência cardíaca e respiratória, temperatura cloacal, oximetria e capnografia se mantiveram estáveis durante todo o procedimento anestésico. Ao final da anestesia foi administrado flumazenil (0,05 mL IV) doxapram (0,5mL IV) e adrenalina (0,05mL IM). O procedimento anestésico escolhido foi seguro, obteve sucesso e não houve intercorrências.

Descrevem-se os achados clínicos, patológicos e histopatológicos de um caso de amiloidose com ruptura hepática em um gato, sem raça definida, macho, de quatro anos de idade, com histórico de anorexia, dor à palpação abdominal e vocalização há dois dias. O animal foi internado e na avaliação clínica verificou-se, além dos sinais clínicos relatados, mucosas oculares e oral pálidas, desorientação, midríase e disfagia. A evolução clínica foi de dez dias e, mesmo com a instituição do tratamento sintomático, o animal morreu e foi encaminhado para realização da necropsia. Macroscopicamente, foi observado hemoperitônio na cavidade abdominal, fígado aumentado de volume, difusamente pálido, friável, com superfície capsular irregular, áreas multifocais de fissuras no parênquima associadas a coágulos cruóricos. A principal lesão microscópica caracterizou-se por dilatação sinusoidal difusa por material eosinofílico hialino, amorfo, opaco e abundante, e áreas multifocais de hiperplasia de células epiteliais de ductos biliares. Na coloração histoquímica de Vermelho Congo esse material corou-se em vermelho alaranjado, confirmando o diagnóstico de amiloidose. A doença representa um desafio na Medicina Veterinária (UFRPE), principalmente para felinos, pois tem um caráter progressivo, difícil diagnóstico clínico, tratamento ineficaz e geralmente com prognóstico desfavorável e sinais clínicos tardios, surgindo apenas quando há comprometimento grave nos órgãos. Dessa forma, é essencial o reconhecimento de mais casos da doença para melhor compreensão da etiopatogenia e auxílio terapêutico.

Published: May 2024

As particularidades anatômicas cranianas das aves são fundamentais para entender os aspectos filogenéticos, contribuindo para a identificação das espécies e na compreensão dos hábitos de vida do animal. Em relação ao contexto clínico veterinário, o conhecimento da região craniana torna-se ainda mais essencial no atendimento mais preciso destes animais, especialmente na análise e interpretação fidedigna de exames de imagens. Desta forma, objetivou-se descrever macroscopicamente a órbita óssea e os acidentes ósseos na corujinha-do-mato (Megascops choliba), utilizando 15 exemplares adultos, sexos indeterminados, advindos por mortes naturais a partir do Hospital Veterinário da Universidade Federal do Paraná - Setor Palotina. Todos os animais foram dissecados para seus crânios serem macerados em água. Posteriormente, estes foram imersos em solução de peróxido de hidrogênio e expostos ao sol para clareamento. Para análise e descrição, utilizou-se uma lupa circular de luz fria e olho desarmado. Assim, observou-se que a órbita se encontrava alongada no sentido rostrocaudal com a presença de uma proeminência supraorbital curta, um processo postorbital largo, um arco suborbital incompleto e um septo interorbital delgado com diversos forames, em que o de maior proporção foi o forame do nervo óptico. Assim, a partir das análises realizadas fornece-se uma descrição mais minuciosa com novas contribuições para a anatomia descritiva da órbita óssea da espécie nativa de coruja, M. choliba, em que se destaca a necessidade de compreender de maneira mais assertiva sobre a singularidade da anatomia da órbita óssea entre as diferentes espécies aviárias e sua anatomia comparativa.

Published: May 2024

A osteomielite é uma doença infecciosa sistêmica grave, caracterizada pela inflamação óssea destrutiva e progressiva, que geralmente possui origem bacteriana, e, ocasionalmente, viral ou fúngica. Objetivou-se relatar o caso de um cão com osteomielite fúngica, detalhando o diagnóstico e a evolução do tratamento. Foi atendido no Hospital Veterinário da Universidade Federal de Uberlândia (HOVET-UFU) um cão, macho, 8,9 kg, mestiço, quatro meses de idade, apresentando hipertermia, hiporexia, linfonodos reativos, claudicação e ferida aberta em membro torácico direito (MTD), além de secreção purulenta e exposição óssea. A radiografia evidenciou fraturas Salter Harris I em cartilagens fisárias da ulna direita e sinais de lesão óssea agressiva poliostótica em MTD. As culturas fúngica e bacteriana isolaram Enterococcus sp., Penicillium sp. e Acremonium sp. O diagnóstico obtido foi osteomielite fúngica. Com base no antibiograma e antifungigrama, foram utilizados os fármacos amoxicilina com clavulanato de potássio, omeprazol e itraconazol e o animal foi acompanhado radiograficamente a cada 30 dias. Após 150 dias os sinais de remodelamento ósseo da articulação e ossos adjacentes eram mais evidentes e o tratamento foi finalizado. O cão permaneceu por 28 meses livre de recidivas. Ressalta-se que a conduta médica diante de uma ferida não deve ser direcionada somente à cicatrização, sendo necessária a realização de radiografia e, em casos de suspeita de osteomielite, exames para exclusão dos diagnósticos diferenciais, bem como, para a escolha do fármaco mais eficaz em cada caso.

Published: May 2024

This case study investigated a multidrug-resistant Staphylococcus pyoderma infection in a pet Rattus norvegicus. The clinical presentation involved a range of clinical signs, including pruritus, inflammation, pustules, and crusts on the skin, indicative of bacterial pyoderma. Conventional and molecular techniques were used, and the pathogen was identified as Staphylococcus chromogenes. The suspected transmission route was through a bite from another rat, although the aggressor was not tested. Initial treatment with enrofloxacin proved ineffective. Subsequently, an amoxicillin + potassium clavulanate treatment resulted in temporary improvement. Nevertheless, the infection relapsed after 30 days, necessitating a repeated course of treatment. The findings underscore the importance of accurate diagnosis, appropriate testing, and adherence to prescribed treatments for bacterial infections. The zoonotic potential of multidrug-resistant Staphylococcus highlights the need for better education of pet owners on transmission risks and treatment compliance. Additional research is essential to explore the transmission routes of this infection, the potential risks to pet owners, and to gain a more comprehensive understanding of Staphylococcus chromogenes pyoderma in domestic rodents.

Published: May 2024

Neoplasias gástricas são incomuns em cães e representam menos de 1% de todos os tumores diagnosticados nesta espécie. Em um levantamento de tumores gastrointestinais em cães, constatou-se que 90% das neoplasias malignas ocorrem no estômago, sendo os tumores epiteliais mais frequentes do que os de origem mesenquimal. O diagnóstico de neoplasias gástricas é difícil e muitas vezes ocorre tardiamente, tornando o prognóstico desfavorável. Em tumores mesenquimais do trato gastrointestinal, a análise imuno-histoquímica é essencial. Este estudo teve como objetivo relatar um caso de leiomiossarcoma gástrico em um cão com morte súbita. O animal foi encaminhado para necropsia no Serviço de Patologia Veterinária da Faculdade de Ciências Agrárias e Veterinária da Universidade Estadual Paulista “Júlio de Mesquita Filho” (FCAV – UNESP) e foram observados dois nódulos no cárdia, cada um com 2,0 cm de diâmetro, esbranquiçados, arredondados e firmes. O estômago apresentava um conteúdo alimentar sanguinolento, e em toda a extensão intestinal o conteúdo era enegrecido. A causa da morte foi choque hipovolêmico. No exame histopatológico, a massa correspondia a uma proliferação de células mesenquimais com leve atipia, cujo diagnóstico foi sugestivo de leiomiossarcoma gástrico. Um tumor estromal gastrointestinal (GIST) é o principal diagnóstico diferencial, então secções histológicas dos nódulos gástricos foram submetidas à análise imuno-histoquímica (IHC). As células neoplásicas foram positivas para S100, 1A4, Desmina e HHF35 e não expressaram DOG1, excluindo a origem das células tumorais de GIST. Este relato demonstra a importância do exame necroscópico para determinar a causa da morte e a técnica imuno-histoquímica para confirmar o diagnóstico de neoplasias mesenquimais.

Published: May 2024

Fish can be regarded as a promising protein ingredient for food fortification and
enrichment. This study aimed to investigate the potential application of Nile tilapia fish as
a dietary supplement. Fish powder was fortified in 0 (control), 5, 10 and 15% levels in dry
ingredients by replacing wheat flour and other ingredients were kept constant. Then,
biscuits were prepared and the proximate composition, physical and texture properties
were determined, as well as sensory acceptance. The addition of fish had a statistically
significant (p < 0.05) effect on moisture, ash, fat, protein, carbohydrate, total energy,
color, water activity, hardness and sensory acceptance. The protein content increased as
much as 2.4-4.6 times as more fish was added. Results show that up to 5% fortification
level, the biscuits were acceptable with improved functional properties compared to the
control. There were significant changes in physical transformation in the biscuits
packaged with polyethylene and aluminum foil at 25°C and 35°C, respectively.
Fortification of fish powder could be used in the production of high-protein biscuits.

Published: May 2024

Rickshaw drivers have a high risk of respiratory disease, especially in the COVID-19
pandemic which is very risky to the respiratory system. The purpose was to determine the
effect of antioxidant intake in food on the lung function of pedicab drivers in Surabaya.
This study was a cross-sectional design, in May-July 2019. The variables of this study
were lung function value and intake of foods containing antioxidants (vitamins A, C, and
E). The research respondents were pedicab drivers in the Surabaya area. The method used
a structured interview method, used the 24-hour recall method. The chi-square test was
used to determine whether there was a difference between the value of lung function and
the classification of intake of vitamins A, C, and E. The respondents of this study were 62
people with decreased lung function, and 62 people without decreased lung function. there
were only 6 respondents who had vitamin A intake per day, while as many as 108
respondents had less level of vitamin A intake per day (87.10%). While the intake of
vitamins C and E was still at a lower level in all respondents (100%). The average intake
of vitamins A, D, and E on holidays was higher than on weekdays. Vitamin A intake has
been shown to affect lung function. There was had significant relationship between dietary
vitamin A intake and lung function in FEV1/FVC value. In addition, further research is
needed to determine other dietary factors and other lifestyles to be able to maintain the
quality of lung health for pedicab drivers.

Published: May 2024

The purpose of this study was to use concentrated feed alternatives with other less
expensive feed alternatives in feeding the Awassi ewes and the impact on milk
composition and matured cheese. A total of twenty Awassi ewes were used, they were
selected in the middle of lactation and divided into two homogeneous groups with weights
(47±1.7 kg) and aged 3-4 years, given two different servings of feed (1.5 kg/sheep/day)
Milk composition was measured weekly, to make cheese, raw milk control (CON) and
Citrus aurantium leaves and tomato pomace (CALTP) is kept separately and chilled.
Results indicated that fat and total solid content were high in milk and cheese
manufactured in the diet that contained CALTP; the proportion of medium-chain fatty
acids (c10-c16) and free fatty acids was lower compared to the diet (CON). While the
proportion of unsaturated fatty acids (UFA) in the diet increased CALTP. Therefore, the
inclusion of CALTP in the diet is helpful because it has a positive impact on the
composition of milk and mature cheese, reduces the cost of the diet and helps recycle byproducts.

Published: May 2024

Adulteration or counterfeiting of food products raises public concerns about the halal
issue. Many issues related to food products such as meatballs, sausages, and corned beef
use pork for counterfeiting. This study aimed to determine a direct polymerase chain
reaction (dPCR) technique for pork DNA detection in processed meat products such as
meatballs, sausages, and corned beef in a short time and at a low cost using specific
primers, ND4 and D-Loop. The study used a direct PCR technique with variations in the
incubation time and temperature of the lysis process on the sample. The concentration of
DNA obtained from the lysis results with variations in incubation time and temperature in
fresh meat and processed meat products was 66.17-469.23 ng/µL, and the purity of DNA
in fresh and processed meat products was 1.70-2.25. ND4 primer was more sensitive to
DNA amplification than D-Loop in processed meat products using direct PCR. Meatballs,
sausages, and corned beef products written on the packaging using beef did not detect any
mixing or addition of pork. Direct PCR can detect pork DNA in processed meat products
such as meatballs, sausages and corned beef.
UTILIZING WASTE FOUNDRY SAND FOR THE DEVELOPMENT OF AFFORDABLE CONCRETE REPRESENTS AN EVOLUTIONARY STEP IN CONSTRUCTION

Published: May 2024

The construction sector is currently experiencing massive expansion and is implementing new methods for efficient and comfortable field labor. As a building material, concrete is important to this sector of the economy. Utilizing natural resources to make concrete comes at a considerable—almost prohibitively high—cost. These problems compel us to either replenish natural resources or find alternative solutions. As a byproduct of the metal casting industry, waste foundry sand currently causes a number of environmental problems. Utilizing this garbage as construction material could lessen the strain on the environment. In the metal industry, foundry sand is a premium, uniformly sized silica sand that is used to create molds for casting both ferrous and non-ferrous metals. Metal casting requires sand that is finer than regular sand. Once it is no longer functional, it is taken out of the foundry and disposed of as "waste Foundry Sand." Concrete made with leftover foundry sand substituted partially for fine aggregate is strong, lightweight, and reasonably priced. Cement, water, additives, fine and coarse aggregate, and cement make up concrete. Each of these components strengthens the concrete in some way. Consequently, a partial or percentage replacement of material will have an impact on the various properties of concrete. It is possible to turn environmentally hazardous waste materials into inexpensive, green building materials. In this work, an experimental investigation is conducted to produce inexpensive and ecologically friendly concrete by varying the percentage of fine aggregate with foundry sand.

RESUMO: O Brasil é o único país do mundo que produz e exporta cera da palmeira nativa carnaúba (Copernicia prunifera). Em 2019, foram produzidas 19.465 toneladas de pó de carnaúba, com valor total de US$ 42,92 milhões. Essas populações de carnaúba de importância socioeconômica têm sido ameaçadas pela invasão biológica da espécie de planta introduzida Cryptostegia madagascariensis, comumente chamada de unha-do-diabo, que pode matar plantas de C. prunifera. Este trabalho investiga os impactos sociais, econômicos e ambientais na cadeia produtiva da carnaúba causados pela invasora C. madagascariensis. Selecionamos dois sítios localizados nos municípios de Granja e Jaguaruana, no estado do Ceará. Foram entrevistados 40 participantes maiores de 18 anos que trabalham ou já trabalharam com a utilização de produtos de C. prunifera. A maioria dos entrevistados tinha idade acima de 41 anos, era do sexo masculino, com baixo nível de escolaridade. Cryptostegia madagascariensis está presente em todas as propriedades, com extensão de invasão de até 75%. O método de controle anual usual para C. madagascariensis é principalmente por meio de corte e queima, mas isso não tem sido eficiente. O controle efetivo da unha-do-diabo teria um forte impacto positivo na biodiversidade e na economia.

In France, blood donations are tested in pools of 96 samples for parvovirus B19 (B19V) DNA to discard plasma for fractionation when it contains high viral loads. Between January 2015 and March 2024, B19V-positive donations decreased during the COVID-19 pandemic, followed by a strong rebound in 2023 and unusually high circulation during winter 2023/24 (ca 10 times higher December 2023–March 2024 vs the pre-pandemic period). Variations over time are probably related to measures implemented to limit SARS-CoV-2 spread.

Authors: Habibi Omid , Youssef Tarik , Naseri Hamed , Ibrahim Khalid
Published: May 2024

In reinforced concrete (RC) structures, accurate prediction of the punching shear strength (PSS) of slab-column connections is imperative for ensuring safety. The existing equations in the literature show variability in defining parameters influencing PSS. They neglect potential variable interactions and rely on a limited dataset. This study aims to develop an accurate and reliable model to predict the PSS of slab-column connections. An extensive dataset, including 616 experimental results, was collected from earlier studies. Six robust ensemble machine learning techniques—random forest, gradient boosting, extreme gradient boosting, adaptive boosting, gradient boosting with categorical feature support, and light gradient boosting machines—are employed to predict the PSS. The findings indicate that gradient boosting stands out as the most accurate method compared to other prediction models and existing equations in the literature, achieving a coefficient of determination of 0.986. Moreover, this study utilizes techniques to explain machine learning predictions. A feature importance analysis is conducted, wherein it is observed that the reinforcement ratio and compressive strength of concrete demonstrate the highest influence on the PSS output. SHapley Additive exPlanation is conducted to represent the influence of variables on PSS. A graphical user interface for PSS prediction was developed for users’ convenience. Doi: 10.28991/CEJ-SP2024-010-01 Full Text: PDF

Published: May 2024

The utilization of nanosilica and cellulose nanocrystals (CNCs) in cement geopolymers remains challenged by intricacies and uncertainties regarding their concentration, posing difficulties in the formulation of systematic geopolymer mix designs. This study aims to formulate models based on Artificial Neural Networks (ANN) capable of forecasting the compressive strength of geopolymers through the utilization of experimentally acquired data. Nanosilica was applied at concentrations of 2%–4% and CNCs at 1%–3%. ANN was modeled using MATLAB to predict the compressive strength of the geopolymer. The results indicated an effect of nanosilica and CNCs on the compressive strength of geopolymer at 2%–4% concentration and 1%–3% CNCs. The best ANN was the GDX training function, purelin activation function, LGD and LGDM learning functions, Lr 0.1 and 0.01 at the number of epochs 3812 out of 25000 and 1774 out of 25000, resulting in the best correlation values of 0.994 and 0.959; the lowest RMSE values are 0.022 and 0.110. The results of the ANN model built based on actual data prove that the model is helpful for accurate simulation to predict the compressive strength of geopolymer cement. This study contributes novelty by optimizing the design model for Geopolymer Cements incorporating nanosilica and CNCs. Doi: 10.28991/CEJ-SP2024-010-03 Full Text: PDF

Recycled concrete aggregate (RCA), derived from waste concrete, can serve as a coarse aggregate in concrete production. However, compared to natural aggregates, RCA exhibits distinct characteristics, including lower strength, higher water absorption, and an increased angular and rough surface. These properties may influence concrete’s workability, compressive strength, and durability. This research investigates the influence of RCA on the properties of High-Fly-Ash Self-Compacting Concrete (SCC). The study explores various replacement levels of natural coarse aggregate with RCA (0%, 50%, 75%, and 100%), alongside a 50% volume fraction of fly ash. Key concrete properties evaluated include workability, compressive strength, flexural strength, and chloride ion permeability. The findings reveal that using 100% RCA in combination with a high fly ash content (50%) produces SCC that meets workability requirements according to EFNARC standards. However, there are trade-offs: the compressive strength decreases by 4.61%, the flexural strength decreases by 3.1%, and chloride ion permeability increases by 57.57% compared to the control sample (using natural aggregates). Notably, the chloride ion permeability of SCC using 100% RCA falls into the category of low permeability. Doi: 10.28991/CEJ-SP2024-010-04 Full Text: PDF

Published: May 2024

Over the years, investigating the behavior of soft soil, stabilized using different techniques, has been recognized as a critical priority for geotechnical engineers. Numerous soil constitutive models have been utilized to simulate stabilized soil behavior, improve strength and ductility, and analyze load-deformation responses. However, further investigation is required to study stabilized soil's time-dependent strength and stiffness, especially at an early curing age. Early strength and stiffness development is crucial in engineering construction for improving building quality and efficiency and minimizing crack risk. Furthermore, estimating UCS from an early age aid in safety evaluation and ground-improvement analysis. Researchers are increasingly recognizing palm oil fuel ash (POFA) as an eco-friendly alternative to traditional soil stabilizers due to its abundant availability. This study proposes an advanced concrete constitutive model to simulate the time-dependent strength and stiffness of POFA-stabilized and cement-stabilized soil due to pozzolanic interactions. The model accurately measures strength and stiffness improvement from an early curing age to 28 days using finite element analysis (FEA) before then comparing the experimental results. Based on the experimental results, the UCS values of palm oil fuel ash-stabilized soil grew to 3.18 MPa and 3.89 MPa after seven and 28 days with an optimum content of 30% (POFA): 10% Magnesium Oxide (MgO). It exhibited a significant increase in early strength with 64.02% compared with cement-stabilized soil. For stiffness results, a slight increment of 9.26% was observed. Employing FEM, the sensitivity of the parameters to stress-strain behavior was investigated. Finally, the validity of the concrete constitutive model to predict the time-dependent strength and stiffness of stabilized soil was proved. Doi: 10.28991/CEJ-SP2024-010-05 Full Text: PDF

Published: May 2024

The multi-planar steel pipe joints are widely used in communication towers, industrial structures, and offshore platforms. The current design formulas consider this joint as a uniplanar joint and account for the multi-planar effect using empirical correction factors. Recent studies deal with this multi-planar joint as a 3D joint but considering certain loading conditions. Hence, the aim of this research is to develop more general AI-based predictive models for the ultimate capacity of multi-planar gapped KK steel pipe joints, considering both symmetric and asymmetric loading conditions. Three AI techniques were applied to a database of previously published works. These techniques are “Genetic Programming” (GP), “Artificial Neural Network” (ANN), and “Evolutionary Polynomial Regression” (EPR). The prediction accuracies of the developed AI models were compared against two previously published formulas. The results indicated that the developed AI models are much more accurate than the previously published formulas. Also, the results showed that both the ANN and EPR models have almost the same level of accuracy (about 92%), but the EPR model has the advantage of presenting a closed-form equation that could be implemented either manually or using software. Doi: 10.28991/CEJ-SP2024-010-07 Full Text: PDF

The purpose of this study was to review the effectiveness of Reduced Working Hours Strategies (RWHS) such as The Four Day Week and explore Irish construction industry perception of how implementing such strategies might impact employee health, safety, well-being, recruitment, retention, and productivity. A mixed-methods research approach was used to uncover any perceptions of benefits, drawbacks and feasibility of RWHSs. The employer’s perspective was based on semi-structured interview data from market leading international construction companies. This was triangulated with survey data from the employee’s perspective to generate richer insights

Results suggested RWHSs could significantly improve working and personal lives of on-site employees. Employees were working on average above 50 hours per week and are aware of the potential benefits of RWHSs particularly with regard to health, accidents, retention and work- life balance. The research indicates that from employer perspective, the study concluded that management personnel were wary of widespread implementation of RWHSs but regarded their implementation feasible in specific aspects of the construction process such as pre-fabrication. Furthermore, they felt increased use of BIM and innovative procurement might facilitate such strategies. Exploring the use of RWHSs was generally perceived as necessary and potentially beneficial, particularly given the industry’s recruitment, retention and productivity issues.

Authors: Wen Jing , Gheisari Masoud
Published: May 2024

Recognizing a severe workforce shortage, the construction industry is now keen on diversifying its talent pool, particularly by attracting female students to construction science, engineering, or management (CM) programs. Despite previous efforts to engage female students in construction, they have not yielded the desired results. To address this issue, this study created a series of stories about women in construction, drawing from interviews with over 30 women currently active in the field. These narratives aim to inspire more female students to consider careers in construction and boost female participation. The stories, integrated with interview content, were disseminated online and subsequently assessed by 53 female undergraduate students. The findings indicated a positive impact, revealing that the stories played a pivotal role in boosting the confidence of these students in pursuing careers in construction. By offering a nuanced perspective into the diverse paths within CM professions, the stories empowered these potential female professionals, enabling them to envision and strive for success in an industry traditionally dominated by males. Offering a tangible and relatable portrayal of women's experiences in the industry, this study provided an easily accessible resource for individuals, organizations, and educational institutions interested in promoting gender diversity in construction.

Published: May 2024

The construction industry in the US is projected to see tremendous growth in the coming decade. However, decreasing high school graduation rates may pose challenges in meeting the increasing demands for a qualified construction workforce. This underscores the need to strengthen the construction management (CM) education platforms across all higher education institutions to equip future graduates with the necessary knowledge and skills. This paper proposes a framework for a collaborative co-teaching model between a university and community colleges to enhance the articulation of the University’s four-year Construction Management and the Community Colleges’ two-year associate degree program. The co-teaching initiative aims to leverage the unique strengths and expertise of each institution to provide students with a comprehensive educational experience grounded in both theory and practice. The study employs a mixed methods approach, including quizzes, surveys, and direct observations, to evaluate the impact of the co-teaching model on student engagement, knowledge retention, and learning outcomes. The paper outlines the design, implementation procedures, and data analysis plans to assess the effectiveness of the collaborative approach. The framework provides a model for integrating industry trends, and diverse instructional perspectives to strengthen construction management education through university-community college collaborations. The study has implications for developing innovative pedagogies to prepare construction management graduates for the evolving real-world demands.
Comparing Two Artificial Intelligence Language Modeling to Evaluate Construction Schedule Understanding
Authors: Sulbaran Tulio
Published: May 2024

Construction schedules are critical for construction projects. Creating a construction schedule is complex. Because it requires a keen ability to understand construction documents and methods. Furthermore, a single construction project could be completed following multiple construction schedules. The preparation of construction schedules is currently done by humans. However, with the advent of Artificial Intelligence (AI), it is possible to think of a future where humans could be assisted by an AI to develop construction schedules. An important step toward having an AI assisting humans in the creation of construction schedules is for the AI to understand construction schedules. Thus, this paper presents the comparison of two language modeling to evaluate an AI's ability to understand construction schedules. This comparison was done following a quantitative experimental research methodology where the independent variables were two AI language models (the Bidirectional Encoder Representation Transformers and the Masked and Permuted Pre-training for Language Understanding) and the dependent variables were accuracy, precision, recall, and F1 scores of the language modeling to understand construction schedule activities. The results demonstrate the impact of language models on the ability of the AI to understand construction schedules. The Masked and Permuted Pre-training for Language Understanding language model had an overall superior performance in understanding construction scheduling activities. This is important as supports the need to expand research projects as the one presented in his paper to identify the best language modeling and improve it for the construction industry.

Authors: Posillico John
Published: May 2024

This research presents a profile of the sought-after competencies of construction managers in leading United Kingdom (UK) construction organizations. In doing so, the work contextualizes the construction organizations influence in terms of revenue and employability; conducts a textual analysis of interpersonal and technical competencies from construction manager job advertisements to ascertain the specific competencies desired by construction organizations; and provides a ranking of said competencies to establish a competencies hierarchy in order to inform curriculum development processes.

Research findings demonstrate that interpersonal competencies have around 70% importance within the role of construction manager. There exists; however, a prevalent vernacular imprecision within the job advertisements about the specific technical competencies for the role exist. Specifically, the lack of digital-esque skills is profound. Thus, a misalignment is present between current educational provision and industry practice regarding the core foundational competencies required of the construction management profession.

This research constitutes an attempt to conduct a textual analysis of descriptive metadata contained within construction manager job advertisements from leading UK construction organizations. Emergent findings revealed specific competencies that are essential to the core of the modern construction manager’s role.
College Credit Earned in High School – A Pilot Study for a Construction Management Program
Authors: Farrow C. Ben , Burt Richard , Smith Katie
Published: May 2024

This pilot study explored Dual Enrollment (DE) and Advanced Placement (AP) credit earned by 130 first-year students into a construction management (CM) degree program at Auburn University. 70% of credits were earned through dual enrollment; 30% of the credits earned were in English Composition, and this credit counted toward the CM degree program. However, for math, history, science, and other social science classes, relatively small percentages of the overall credits earned counted toward the CM degree. These findings suggest that DE and AP credit can be a valuable way for construction management students to advance in their studies. However, some courses may not be accepted by all universities, and some courses may not align with the specific requirements of CM programs. Given the continued rise in DE and AP credit coupled with the high cost of education, it is important for CM programs to explore ways to assist students in utilizing credit earned. This may include expanding the credit offered and providing students with personalized academic advising to help them plan their coursework. By taking these steps, CM programs can help students to make the most of their DE and AP credit.
