Authors: De la Peña Portero Alicia
Published: December 2023

En este artículo se presenta un estudio de casos en el que se investiga acerca de la percepción de los participantes (estudiantes universitarios hablantes no nativos de español en estancia de estudios en España) sobre diferentes aspectos de una tarea colaborativa de escritura y evaluación de textos argumentativos con rúbrica. Para ello, se analizan los cuestionarios de percepción y las entrevistas semiestructuradas que se realizaron al término de la tarea. Aunque con ligeras diferencias entre los grupos virtuales y presenciales, los resultados muestran que ambos procesos colaborativos son bien recibidos y que los participantes perciben una mejora en su nivel de español y en el desarrollo de una serie de competencias transversales. Se anima a continuar con investigaciones relacionadas con el desarrollo de la alfabetización académica en la universidad.
Metodologías activas para el tratamiento de errores gramaticales en el aula de ILE
Authors: Chaves-Yuste Beatriz
Published: December 2023

Las metodologías activas ofrecen nuevas formas de comunicar y conexionar la educación con la realidad existente (Giroux, 2008) y mejoran el aprendizaje de lenguas extranjeras. La finalidad de la presente investigación es analizar si el uso integrado de seis metodologías activas (aprendizaje basado en tareas, aprendizaje cooperativo, instrucción basada en contenido, aprendizaje invertido, gamificación y aprendizaje basado en el juego) ayuda a disminuir los errores gramaticales de los estudiantes. Para proceder a tales efectos, se realiza una intervención empírica exploratoria en la asignatura de inglés como lengua extranjera fundamentada en dichas metodologías, tomando como muestra de estudio un grupo de 122 estudiantes de educación secundaria. Se utilizaron como instrumentos de recogida de datos dos test con el formato de entrevista. El análisis de los datos obtenidos confirma las hipótesis, ya que se observa una reducción significativa en el número de errores gramaticales tras el uso integrado de estas metodologías activas.
Intercambios virtuales en formación docente. Estado del arte y desafíos para la enseñanza de la lengua
Authors: De Luca Natalia
Published: December 2023

En este artículo, se presenta una revisión de antecedentes por investigaciones que han tomado como objeto, desde diferentes enfoques y metodologías, una práctica educativa relativamente novedosa: los intercambios virtuales en formación docente. Esta práctica pedagógica requiere de una revisión de la bibliografía especializada que tenga en cuenta esa heterogeneidad constitutiva a la hora de presentar los avances en el campo. En este sentido, el presente artículo se organiza a partir de tres dimensiones: primero, parte de investigaciones de carácter general sobre intercambios virtuales; segundo, se indaga qué se ha estudiado en el ámbito de la formación docente. Y, finalmente, a raíz del recorrido bibliográfico, se señalan los aspectos que convierten a estos proyectos colaborativos interculturales en una práctica significativa de reflexión lingüística y de metacognición para futuros docentes de lengua; así como también las preguntas vacantes que constituyen un promisorio punto de partida para pensar los desafíos en la educación lingüística.
An exploration of linguistic mediation activities in repair sequences: The case of a plurilingual youth participant in an after-school digital storytelling project
Authors: Zhang Miaomiao
Published: December 2023

This article uses Conversation Analysis (CA) to explore the linguistic mediation activities carried out by a plurilingual teenager in interaction with a linguistically and culturally diverse peer group, with a focus on repair sequences. The analysis centres on: 1) the placement of repair, that is, repair that is forward-oriented or backward-oriented; 2) the object of repair, focusing on repair directed at the code and repair directed at the message; 3) procedures by which the linguistic mediator is selected, that is by other-selection or self-selection; 4) interactional procedures for completing repair, focusing on translation and collaborative turn sequences. This study contributes to enhancing understandings of the mechanics of linguistic mediation in contexts of linguistic and cultural diversity from an interactional perspective, and among youth, in the context of an after-school educational program.

Authors: Almeida Danusa Mendes , Rocha Antonia Rozimar Machado e , Martins Ivan Carlos Costa
Published: December 2023

Esta investigação é o recorte de um estudo realizado no estágio pós-doutoral e tem como escopo central analisar a contribuição das pesquisas sobre a fase do associativismo docente para a investigação da organização e da ação coletiva dos professores da educação básica. Trata-se de uma pesquisa do tipo bibliográfica, que utilizou um corpus composto por 34 produções acadêmicas resultantes de um levantamento de dados no site da BDTD e no Catálogo de Teses e Dissertações da CAPES. O estudo constatou que, a despeito de tratar-se de um campo de pesquisa ainda em fase de consolidação, os trabalhos na área têm contribuído para a conformação de novas perspectivas teórico-metodológicas para a investigação da organização e da ação coletiva docente, uma vez que existe uma tendência em indicar o período do associativismo como uma pré-história do movimento sindical docente.

Authors: Borges de Aguiar Claudio Gustavo , Monteiro Patricia Ortiz
Published: December 2023

Esta pesquisa, qualitativa e teórica, investiga o panorama das pesquisas sobre as representações sociais na região amazônica, no Brasil, presentes em teses e dissertações disponibilizadas no banco de dados da Capes. O arcabouço teórico adotado inclui a Teoria das Representações Sociais, bem como a contextualização sobre temas pertinentes à discussão. A análise das teses e dissertações dos últimos sete anos revela uma lacuna na literatura em relação à região amazônica. Diante disso, esta pesquisa tem a intenção de apresentar um panorama do que foi produzido, evidenciando a escassez de estudos, e ajudar a estabelecer uma base para futuras pesquisas. A compreensão das representações sociais pode contribuir para o desenvolvimento de políticas de conservação da biodiversidade e sustentabilidade, incorporando perspectivas locais e profissionais, inspirando pesquisadores, educadores e formuladores de políticas a reconhecerem a importância das representações sociais na construção de um futuro sustentável, tanto para a região quanto para o planeta.
Adoniran Barbosa e a trilha sonora da cultura brasileira nos anos 50: uma perspectiva cultural do desenvolvimento segundo Celso Furtado
Authors: Monção Junior Roberto Gomes , E Silva Fabiana Felix do Amaral
Published: December 2023

Baseando-se na análise da música popular de Adoniran Barbosa, este estudo promove uma discussão sobre cultura e desenvolvimento, de acordo com as ideias de Celso Furtado. Especial atenção é dada às concepções de cultura, criatividade, modernização e desenvolvimento endógeno. Do ponto de vista teórico, a análise do discurso é adotada como uma ferramenta que reconhece o sujeito como parte do coletivo, enfocando o assujeitamento inconsciente ao conhecimento coletivo. A pesquisa qualitativa explora o papel do cantor popular como um cronista que internaliza a visão coletiva, refletindo que neste processo não há apenas tensões e conflitos entre grupos sociais, mas a imposição de uma cultura que se considerava superior e que marginalizou outras culturas. Conclui-se que a busca por alternativas de desenvolvimento exige a defesa do desenvolvimento endógeno, conforme proposto por Celso Furtado, e uma conexão sólida entre esse processo e o sistema cultural.

Published: December 2023

A resistência mecânica do solo é transmitida pelas forças coesivas entre as partículas sólidas e pela resistência ao atrito encontrada entre elas. Neste contexto, este estudo testou a hipótese de que os manejos de plantas invasoras e culturas de cobertura utilizadas como adubos-verdes nas entrelinhas de uma lavoura cafeeira alteram a resistência mecânica do solo à penetração do cone. O estudo foi conduzido no município de Londrina, mesorregião norte do Estado do Paraná, Brasil, na Estação de Pesquisa e Inovação do Instituto de Desenvolvimento Rural do Paraná, IAPAR-EMATER (IDR-Paraná) em uma lavoura cafeeira implantada no ano de 1978 da cultivar Mundo Novo, espaçamento de 3,5 m entre ruas por 2,0 m entre covas com duas plantas por cova. Em agosto do ano de 2008, o experimento foi instalado em blocos casualizados (DBC) com sete tratamentos e quatro repetições. O solo da área de estudo é classificado como LATOSSOLO VERMELHO Distroférrico (LVdf), muito argiloso (82 dag kg-1 de argila, 13 dag kg-1de silte e 5 dag kg-1 de areia total). Os manejos e coberturas nas entrelinhas dos cafeeiros avaliados foram os seguintes: 1-) capina manual operações realizadas com o auxílio de uma enxada (CAPM); 2-) roçadora costal-manual (ROÇA); 3-) herbicidas de pós + pré-emergência (HERB); 4-) planta de cobertura amendoim cavalo - Arachis hypogeae (AMCAV); 5-) mucuna anã Mucuna deeringiana (Bort.) Merr (MANA); 6-) sem capina nas entrelinhas (SCEE); 7-) sem capina nas entrelinhas e na saia dos cafeeiros (CONT). Em outubro do ano de 2010 (26 meses após a instalação do experimento), amostras de solo com estruturas preservada foram coletadas em anéis volumétricos de 5,1 cm de altura por 5 cm de diâmetro (100 cm3), no centro das entrelinhas dos cafeeiros, nas profundidades 2 ― 7 cm, 12 ― 17 cm, 22 ― 27 cm e 32 ― 37 cm, totalizando 112 amostras. Ensaios de resistência mecânica do solo à penetração (RP) foram realizados em cinco pontos adjacentes aos locais de coleta das amostras com estrutura preservada, com o auxílio de um penetrógrafo com haste de 620 mm, diâmetro do cone de 12,83 mm e ângulo do cone 30°. Os valores de densidade do solo para as entrelinhas da lavoura cafeeira para as quatro profundidades podem ser estimados a partir do conteúdo de carbono orgânico total por meio da equação polinomial quadrática: Ds = -0,0049 COT2 + 0,1125 COT + 0,5688, R2 = 0,99, p = 0,049. Os métodos mecânicos de controle de plantas invasoras (Trat 1 - capina manual e Trat 2 - roçadora mecânica portátil) e o cultural Trat. 4 – amendoim cavalo proporcionaram camadas de solo com impedimento ao crescimento radicular valores superiores a 2.000 kPa entre 10–20 cm de profundidade.

Published: December 2023

Este trabalho tem como propósito abordar as usinas termelétricas flutuantes a gás para a geração de energia elétrica. Ao longo dos anos, o gás natural conquistou crescente popularidade e espaço na integração da matriz energética. O Brasil destaca-se como um dos poucos países no mundo dotado de diversas e abundantes fontes naturais de energia renovável. Contudo, apesar do vasto potencial para geração de energia limpa, foi autorizada a instalação de uma usina termelétrica flutuante a gás na Baía de Sepetiba, situada na região da Costa Verde, no Estado do Rio de Janeiro. A empresa Karpowership obteve autorização para atuar como produtor independente de energia e estabelecer e operar quatro usinas termelétricas no país. Para alcançar esse fim, é necessário que a empresa se ajuste às normas vigentes e respeite as regulamentações para garantir o pleno funcionamento das instalações. Assim, este trabalho tem como objetivo principal analisar o mercado global das usinas flutuantes movidas a gás natural liquefeito (GNL) e compará-lo com a termelétrica instalada na Baía de Sepetiba. Dessa forma, foi realizada uma análise para identificar os países que adotam essa tecnologia, juntamente com uma comparação com outras formas de geração de energia elétrica.

Authors: Chiacchio Adolpho Dias , Ramos Giovana Lis Galvão , Costa Alice Freitas , Fonseca Juliana Barros , De Siqueira Sarah Brito , Do Nascimento Guilherme Nobre Lima
Published: December 2023

O presente estudo visa a investigação do potencial antimicrobiano do extrato da folha da planta Guazuma ulmifolia Lamarck, conhecida como Mutamba, evidenciando seu uso medicinal. Explorou-se o método de preparo do extrato etanólico por rotaevaporação e conduziu-se testes de atividade antimicrobiana, incluindo o teste de difusão por poço e a determinação da Concentração Inibitória Mínima (CIM). Os resultados revelaram atividade antimicrobiana apenas contra Staphylococcus aureus, porém em concentrações consideravelmente altas, sugerindo limitações no uso farmacológico eficaz do extrato para ação antimicrobiana ampla. Conclui-se que, pelo fácil cultivo da planta e pela ampla distribuição no Brasil, é importante investigar não só sua possível ação antimicrobiana, mas também outros potenciais efeitos terapêuticos. Recomenda-se, portanto, pesquisas adicionais para compreender melhor seus efeitos terapêuticos e garantir sua segurança antes de sua aplicação como fitoterápico.

RESUMO

Introdução: Os acidentes ofídicos são um problema de saúde pública no Brasil, sendo responsáveis por cerca de 4.553casos por ano no Tocantins. A região norte do país é a mais afetada, representando aproximadamente30% dos casos notificados. Além disso, o Tocantins é um estado localizado na região norte do Brasil, com uma área de 277.620 km² e uma população de cerca de 1,8 milhão de habitantes. Nesse sentido, o objetivo deste estudo foi avaliar o perfil epidemiológico dos acidentes ofídicos no estado do Tocantins, no período de 2017 a 2022. Métodos: Os dados foram obtidos do Sistema de Informação de Agravos de Notificação (SINAN), do Ministério da Saúde. Foram incluídos todos os casos de acidentes ofídicos notificados no estado do Tocantins, no referente período - as variáveis analisadas foram: sexo, idade, ocupação, espécie de serpente, tempo de atendimento e soroterapia. Resultados e discussão: Os resultados deste estudo mostraram que os acidentes ofídicos são um problema de saúde pública importante no estado do Tocantins. A incidência de acidentes ofídicos no estado é superior à média nacional, sendo a segunda maior entre os estados da região norte; de acordo com os dados obtidos, homens serem mais acometidos do que as mulheres é consistente com os resultados de estudos realizados em outras regiões do Brasil; a faixa etária mais acometida 20 - 39 pode ser explicada pelo fato de que esta é mais ativa e está mais exposta a acidentes ofídicos, por meio de atividades como agricultura, pecuária e lazer; quanto à ocupação mais acometida, os resultados são consistentes com a distribuição geográfica das serpentes venenosas no estado, que são mais abundantes em áreas rurais; o gênero de serpente mais notificado é amplamente distribuído no Brasil, e possui um veneno potente. Conclusão:  Os resultados deste estudo indicam que o Tocantins é um estado com alta incidência de acidentes ofídicos. As ações de prevenção e controle deste problema devem ser intensificadas, com foco na educação em saúde, na redução da exposição ao risco e no acesso a serviços de saúde de qualidade.

Dental traumas are seen in the literature as injuries that are caused by impacts on the teeth and/or hard and soft tissues inside or outside the oral cavity. The objective herein is to report the technique performed at the Amazonas State University on a 3-year-old patient, who had necrotic tissue in the anterior region of alveolar and gingival mucosa, due to trauma suffered in this region 14 days previously. Radiographically, the dental elements showed no impairment. First, scraping of necrotic tissue was performed, which resulted in severe exposure of periosteal tissue, followed by tissue synthesis by suturing and the application of surgical cement for the purpose of cicatricial stimulation. The elements 51 and 61 presented mobility, thus semi-flexible containment were performed for stabilization of the elements. The follow-up was carried out over a period of 12 months, and it was concluded that the therapeutic approach was the correct one for the case of dentoalveolar trauma as described above. Emphasis of the importance of the collaboration of those responsible for the child’s oral hygiene and good immune response of the patient resulted in an effective treatment with favorable outcome.

Authors: KELTEN Onur , GÜLDAŞ Abdülmecit
Published: December 2023

The article discusses the increasing interest in natural fibers as a substitute for synthetic fibers in the development of composites due to the depletion of crude oil reserves, environmental concerns and regulations targeting the reduction of carbon emissions. The mechanical properties of natural fibers are closely linked to their chemical composition and structure, which can be influenced by various factors such as harvesting time, growth conditions, storage practices, extraction techniques and pre fabrication chemical treatments. The article also explains the finite element analysis steps for a sandwich structure created using hemp fibers with a 3 mm diameter and 20 mm spacing between two carbon prepreg layers for a 3-point bending test.Finally, numerical analysis outputs of sandwich structures created with hemp fibers at intervals of 10 mm, 20 mm, and 30 mm, and diameters of 2 mm, 3 mm, and 4 mm, are presented graphically to demonstrate the effects of changes in hemp fiber spacing and diameter on stress.
ETHNOBOTANICAL ANALYSIS OF PHYTONYMS AND PLANT-RELATED GLOSSES MENTIONED IN BUJANGGA MANIK, A PRE-ISLAMIC SUNDANESE TEXT (15TH CENTURY JAVA, INDONESIA)
Authors: Mulyanto Dede , Iskandar Budiawati Supangkat , Iskandar Johan , Indrawardana Ira , Aufa Ari Abi
Published: December 2023

This study aimed to identify and analyze ethnobotanical data on phytonym, utilization, and cultural value of plants mentioned in an Old Sundanese text. Since plants are mentioned with their vernacular names, identification was based on an exhaustive bibliographical search of the respective scientific name. A comprehensive investigation led to the identification of a total of 85 Old Sundanese phytonyms, which represented vernacular names for 79 distinct plant species. Furthermore, by considering the number of identified species from the plant-related glosses, 93 species belonging to 57 genera and 44 plant families were registered. Among these plant families, Arecaceae (12 species), Poaceae (nine species), and Fabaceae (six species) exhibited the highest number of identified species. In addition to the phytonyms, 36 phytotoponyms, which utilize vernacular phytonyms to designate settlements, hermitages, ports, mountains, and rivers were identified. It was worth noting that the majority of the plants associated with these phytotoponyms were indigenous. Meanwhile, only 13 species were traced back to the pre-Columbian exchange period during the Austronesian migration and the Indianization-Sinicization era in IndoMalayan history. The result showed that the predominantly mentioned utilization included beverage production, textile manufacturing, vessel craftsmanship, betel quid preparation, perfume creation, and incense production. Among the identified species, Areca catechu emerges as the most frequently mentioned in the text, along with Graptophyllum pictum and Cordyline fruticosa, which were also considered as possessing profound spiritual value due to association with heavenly realms. Furthermore, the text highlighted that the production of plant-based fragrance products, also referenced in the celestial domain, held significant prominence in global trade during the 15th century
The Effect of Coconut Powder on Asphalt Binder Performance under Laboratory Conditions
Authors: Yousif Rana , Tayh Sady , Jasim Abbas F.
Published: December 2023

Bituminous concrete mixture is the most widely used structural layer in flexible pavements. The surface layer of the paving is exposed to repeated loads in addition to changes in temperature, especially during the summer, when the temperature approaches the softness point of the asphalt binder, and therefore, it is subject to multiple types of failure, especially rutting. The properties of asphalt binder and asphalt mixtures can be improved by using various additives. Coconut shell powder, made from the dried husk of coconut fruit, is a popular addition in many industries. As a result of its high strength and stability, this waste material can be recycled into functional structural components such as composite material reinforcement. This study was conducted to evaluate the performance of coconut husk as very fine particles passing through sieve number 200 (0.075 mm) to modify the asphalt binder. The modifier was added at rates of (0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10) by the weight of asphalt binder. Two asphalt binder types, 80/100 and 40/50 penetration grade, were used in this study. All asphalt samples were tested for penetration, softening point, rotational viscosity, and dynamic shear rheology. The results showed that the modified samples had better physical and rheological properties compared to the base asphalt binders. However, (7-8%) replacement of coconut husk powder, regardless of the base asphalt binder, yielded the best performance among the modified binders. In conclusion, coconut powder has significant potential as a road-building material due to its impact on the viability of the road construction sector
Evaluation of Consolidation Degree from CPTu using Rahardjo (2016) Method – Case Study of Consolidating Soil in East Kalimantan
Authors: Lie Edwin
Published: December 2023

A geotechnical investigation comprised 13 CPTu and 23 dissipation testing were performed on a site in East Kalimantan due to landslide triggered by 15 to 30m thick soft clay underlying 75m high overburden embankment. The investigation covers an area of about 250m x 275m wide on the area next to the toe of the embankment. From geological map, the site situated at borders of Balikpapan Formation (Tmbp) and Kampung Baru Formation (Tpkb) with Alluvium (Qa) formation from Heliosen period nearby. Measurement from penetration showed high pore-water pressure higher than the hydrostatic pressure. Result from dissipation testing showed that the soft clay is still consolidating with residual excess pore pressure (uf) still exist. Rahardjo (2016) Method was developed using CPTu data as its basis especially soft clay data to determine overconsolidation ratio (OCR). However, it can also be used to determine the degree of consolidation. The method uses Pore Pressure Ratio (Bq) value, excess pore pressure divided by net cone resistance – Bq = Δu/(qt – σv0), which was obtained when performing CPTu test. The formula proposed was 1/(1.2Bq+0.1). The method stated that the value of Bq=0.75 equals to OCR=1 which is showing a normally consolidated clay. Bq value higher than 0.75 will show a degree of consolidation of a consolidating soil and for Bq value lower than 0.75 will show an OCR value of overconsolidated soil. Applying Rahardjo (2016) Method to the dissipation data performed showed an agreement on soft clay where the soil is still consolidating. However, when applied to over consolidated soil near surface this method will show a greater OCR value.
Statistical Analysis of Core Strength of Deep Cement Mixing Ground
Authors: Namikawa Tsutomu
Published: December 2023

Cement-treated ground by deep cement mixing has been used for several geotechnical structures widely. In quality assurance processes of this method, statistical parameters, mean and standard deviation, of unconfined compressive strength of cement-treated soils are used. The mean and standard deviation are normally used to assure the quality of the improved ground. These parameters evaluated from core strength data are the sample statistical parameters, indicating these parameters involve the statistical uncertainty. Thus the evaluation of the statistical uncertainty is needed when assuring the quality of the improved ground precisely. Moreover, the spatial correlation exists in core strength data. The statistical uncertainty emerging in the evaluation of the population statistical parameters is possibly affected by the spatial correlation. This paper presents the statistical analysis of core strength data observed in several deep cement mixing projects. The mean, standard deviation, and autocorrelation distance, were adopted as the statistical parameters of the strength. The type of the probability distribution of the core strength was investigated by the Kolmogoronv-Smirnov (K-S) test. The goodness fit of the normal and log-normal distributions was examined against the core strength data. The autocorrelation distance, which is the parameter representing the characteristic of the spatial correlation, was calculated from the distribution of the core strength using the maximum-likelihood method. The statistical uncertainty of the statistical parameters was evaluated using a Bayesian inference approach. In the Bayesian inference approach, a Markov chain Monte Carlo method was adopted to calculate the realizations of the population statistical parameters. The analysis results indicated the statistical uncertainty included in the statistical parameters is significantly affected by the spatial correlation.

Pengerang is a municipality in Kota Tinggi district in Johor at the southern tip of the Peninsular Malaysia. It is home for the mega oil and gas hub Pengerang Integrated Petroleum Complex (PIPC) in Southern Johor state, which is one of the region’s largest hubs for oil and gas, petrochemical industries, oil storage and trading activities. The area is experiencing significant development, both residential and commercial in nature. In this development plan, the retaining wall system plays a crucial role in providing a larger development area, enhancing the aesthetic view, and achieving a higher elevation platform. The focus of this paper is on an internally stabilized reinforced soil wall system which involves reinforcing the soil with high stiffness geocomposite reinforcement and utilizing modular segmental blocks as facing elements. This combination creates a 1 vertical: 0.14 horizontal gradient (82°) wall that is implemented for a mixed development at Pengerang. The single-tier reinforced soil wall reaches a height of 13 m. In addition, the maximum 14 m high wall was designed as a two-tier wall and the maximum 19 m high wall was designed as a three-tier wall. The design of the reinforced soil wall includes the evaluation of various potential internal and external failure modes. This paper also discusses the construction sequences employed for the reinforced soil wall. Ultimately, the combination of the high stiffness geocomposite reinforcement with modular segmental blocks has proven successful, resulting in a constructed wall that satisfied the client requirements

Clay shale is a sensitive soil material that easily experiences weathering if exposed to open air, sunlight, water. Weathered clay shale is commonly located near the surface and has a soft consistency due to surface water infiltration. Referring to this condition, weathered clay shale is prone to experience soil movement if backfill work is conducted on the top side of weathered clay shale material. Therefore, to minimize the potential of soil movement during backfilling, soil replacement using soil cement is recommended to be conducted to gain higher soil shear strength and to prevent excessive water infiltration to the fresh clay shale. To gain further understanding, a comprehensive study about the replacement of weathered clay shale using soil cement for bridge approach embankment in Purwakarta was carried out. This study comprises site observation, field data collection, laboratory test, explanation about implementation and quality control. The stages in implementation of soil cement is carried out in several stages such as : evaluation of soil condition on the project site, checking the suitability of local soil for the soil cement stabilization, conducting field test trial mockup followed by quality control, conducting crumb test and mechanical properties test for soil cement mixture. Based on assessment results, the soil cement mixture shall be directly compacted after the soil cement mixture is homogeneous to prevent segregation and shall be given a curing time of at least 3-7 days without additional water to gain better soil shear strength. Furthermore, according to the crumb test result, soil cement material was identified as quite impermeable which is verified by evidence that there was no significant change in water content and the soil cement sample could still stand firm after soaked for 7 days.
A Case Study of Peat Ground Improvement by Vacuum Consolidation in Hokkaido, Japan
Authors: Hayashi Hirochika , Hijiri Hashimoto
Published: December 2023

This paper presents the field performance of vacuum consolidation method on peat ground and some technical learning from the field trial. Peat is well known to be a soft soil which has particular characteristics, including extremely high compressibility and greatly low undrained shear strength. In case of an embankment building over peat ground, sliding failure and large settlement often occur due to the particular characteristics. For actual construction sites on peat ground, therefore, some kinds of ground improvement methods are commonly used. One of the methods is the vacuum consolidation method which can load vacuum pressure with the soft ground by vacuum pumps and prefabricated vertical drains to accelerate the consolidation and increases the strength of soft ground. Peat ground distributed widely in Hokkaido, the northernmost land of Japan. A full-scale trial construction of vacuum consolidation was conducted in a highway project over peat deposit in Hokkaido of Japan to reveal its performance. Although the undrained shear strength of peat ground at the trial construction site was approximately 10 kN/m2 and extremely low, a 10.7 m high embankment was successfully built in only 45 days. This experimental fact implies that the vacuum consolidation method has extremely high effects in improving the stability of peat ground. Based on a result of the trial construction, it also revealed that the increase of undrained shear strength of the peat ground using vacuum consolidation and the suitable spacing of prefabricated vertical drains for peat ground.

Chemical grouting is a method to improve or accelerate the solidification process on a loose soil. The implementation of improper chemical grouting may lead to affect the safety level of groundwater; thus, the technical ability and safety should be analyzed comprehensively to prevent degenerative effect on environment. Volcanic soil is targeted on this research coherent to the abundancy in Indonesia. In this study, a field scale test was conducted to validate leaching test results that were obtained in the lab and to confirm the safety of sodium silicate-based chemical grouting. In addition, the geoelectric survey was conducted to ensure the flowing of groundwater by observing resistivity of soil layer. On laboratory test result, the significance basic pH was observed, in consequence some test revealed an increase in concentration of heavy metals. The bench test was conducted in Jatinangor area’s soil as a representative of Indonesian soil to validate the laboratory result. During the bench test, the pH of ground water was monitored continuously for 5 months, where a slight increase in the pH values of ground water was observed. In addition to that, water samples were collected and analyzed in the laboratory to examine heavy metal contamination in ground water on the 18th day after the chemical grouting injection was started. However, the increased concentration was not found which indicates the pH control shall be the main control of metal leaching. As the conclusion, pH monitoring as early measurement for chemical grouting effect on groundwater is proposed to be set as standard for chemical grouting work.

Introduction: As in almost all medical institutions providing health care service, violence is also one of the serious and vital challenges in emergency deparments (EDs). Researches and reports show that prevalence of violence in EDs is increasing day by day. The aim of this study is to determine reasons, frequency and types of violence applied by patients and their relatives against healthcare professionals and to discuss the possible measures that may be taken.

Material and Method: The health professionals working in EDs of our hospital were asked for filling out surveys voluntarily by talking face to face. Chi-square test was used so as to compare the categorical variables between two groups. Results were presented as mean ±SS or frequency (percent). In 95 %percent confidence interval, p < 0.05 was accepted as significant.

Results: A total of 343 volunteers participated in our study; % 44.3 of them were female (n=152) and %55.7 of them were male (n=191). Mean age was 30.30 ± 7.67 years. Most of the participants were nurses and midwives (n=91, % 26.5). It was realized that %77.6 of staff have been at least one time exposed to violence during their working hours, mostly male patients resorted to the violence (% 83.8) and predominantly they were average of 30-41 age (% 76.7). The most common type of violence was emotional/verbal violence (%84.2). When the violence has been examined according to days and hours, they were mostly exposed to violence every week day (% 26.7); between the hours of 18:00 and 24.00 (% 71.4). Suggestions of the participants to reduce workplace violence in the ED were constitution of heavy punishments, increasing the number of security personnel and making legal arrangements, respectively.

Conclusion: Besides being a deep trouble worsening day by day all over the world, the violence in emergency services has also been turning out an unignorable problem in our EDs. Efficient studies that may be useful and embrace permanent solutions should be carried out so as to prevent violence exposed by health professionals having to work under heavy conditions and to care for a great number of patients.
