Published: February 2024

The heavy rainfall during the night of October 28-29, 2019, caused a landslide in the Ngouache 4 neighborhood in Bafoussam in the West Cameroon region. This landslide caused 43 deaths, several missing persons and the destruction of several houses and plantations. The present investigation attempts to find the causesof this landslide. First, the landslide area was identified and heavy dynamic penetrometer surveys were conducted. Next, intact and reworked samples were taken and, finally, slopes were measured on the slide area to determine the soil parameters. The results of the heavy dynamic penetrometer showed the presence of altered clay layers which, when saturated, exert hydrostatic pressure and unbalance the soil. The granulometric analysis noted a soil with more than 50% of grains of ϕ>80µm with liquidity limits between (50-65.3%), a consistency index between (1.01-1.24), a low cohesion between (0.22-0.30 bars) for a high internal friction angle (20.72°-23.86°), slopes between 48° and 56° and a degree of saturation Sr between (80.5° and 139.9°). These characteristics associated with the large water columns of the night of October 28 to 29, 2019 demonstrated that the water had exerted a hydrostatic pressure having made the clay material reach the limit of plasticity to the creep and raised the level of the water table. Thistherefore promoted the saturation of the substrate yet the increase in the water content reduces the cohesion of the materials and that triggered the saturation at the origin of this deadly slide. The results of the present research may help the public authorities in the decision making regarding the characterization and the securing of risk zones.

Dengue virus infections exhibit a spectrum of clinical manifestations, ranging from asymptomatic cases to severe disease, with the potential for fatalities if not managed effectively.
Hematology factors significantly contribute to the severity of dengue virus infection.

 
Abstract
Background: The escalating incidence of dengue cases in Surabaya, Indonesia, underscores the imperative to comprehend the hematology profiles and disease severity in pediatric patients affected by dengue virus infections (DVI). As the prevalence of DVI continues to surge, understanding the nuanced clinical manifestations becomes paramount for effective management and mitigation of the disease burden. Objective: This study aimed to characterize the hematology profiles and the disease severity of dengue virus infections (DVI) among pediatric patients hospitalized at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia throughout 2019. Material and Method: A retrospective descriptive cross-sectional study was conducted using secondary data from medical records. Pediatric patients aged six months to 18 years were enrolled. A total sampling method comprised 67 patients meeting the inclusion criteria. Result: Severe thrombocytopenia was most commonly observed in dengue hemorrhagic fever (DHF) III cases (36.4%), while leukopenia was predominant in DF cases (42.2%). High hematocrit levels were more prevalent in DHF III cases (27.3%), and high hemoglobin levels were most frequently identified in DHF II and DHF III cases (33% in each case). Significant differences in DVI severity were observed in platelets and hemoglobin levels (p=0.0002 and p=0.0066, respectively) but not in leukocyte and hematocrit levels. Conclusion: Mild thrombocytopenia was prevalent in Dengue Fever (DF), while severe thrombocytopenia was most prevalent in Dengue Hemorrhagic Fever (DHF) grade III. Leukopenia was prominent in DF patients, and platelets and hemoglobin levels varied across severity of DVI. These findings provide insights for improved clinical management and diagnostic criteria refinement.

The critical position of concrete plays a decisive role in engineering applications where extreme high-temperature environments severely affect the durability and life cycle of concrete structures. Experiments were conducted to mimic fire and extreme high-temperature environments, using different activities of nano calcium carbonate (NC) and nano silica (NS) to replace cement mixed concrete at 2.5%, 3.0% and 3.5% respectively, and a series of data analysis of nano concrete to derive patterns of performance change and drive new momentum for progress in the concrete industry. Experimental studies were conducted to explore the decaying changes in the mechanical properties of nano concrete after the concrete modified with composite nanomaterials was heated at different temperature environments of 25°C, 200°C, 400°C and 600°C. The results showed that the mechanical compressive strength of the nano concrete increased by 17.05%, 21.81% and 23.00% at 7 days respectively compared to the control concrete, and the nano 3.0% admixture showed excellent mechanical properties in the range of 25°C to 600°C. The results show that the strength checks of the nano-concrete cube and cuboid specimens after heating through different high-temperature environments were similar in rebound tests and no significant differences were found.

Published: February 2024

Application of signalling at junction can make the delay time longer. The delay time at the junction will be related to the amounZt of fuel consumption of vehicles. In this study, research will be conducted on delays with fuel consumption at the Degolan Junction. The purpose of this study was to determine the comparison of vehicle fuel consumption between the unsignalized junction and signalized junction. Junction performance analysis was carried out based on IHCM 1997. The fuel consumption analysis is carried out based on the length of the delay using the equation from LAPI-ITB. Furthermore, data analysis was carried out using linear regression analysis. Based on the results of the analysis, it was found that the average fuel consumption at the Degolan Junction when the junction conditions were not signalled was 9.553 liters/junction. Meanwhile, when signalling is applied to the Degolan junction with details, alternative 1 produces an average fuel consumption of 40,144 liters/ junction, alternative 2 produces an average fuel consumption of 40,646 liters/ junction, and alternative 3 produces an average fuel consumption of 39,937 liters/junction. The results of the analysis show that the performance of the junction in the form of delay has an influence on fuel consumption.

The process of building a new Yogyakarta airport in Kulon Progo District or New Yogyakarta International Airport (NYIA) continues to accelerate. The document on the analysis of environmental impacts (Amdal) is still in the process of preparation. Airport development, has implications for productive land grabbing, settlement evictions, lost probability at the site plan and at the location of supporting infrastructure. In fact, there was no study on tsunami risk reduction in the formulation of environmental impact (Amdal), so there is no guarantee of safety. On the analysis of the risk probability in the pavement runway project is divided into five probabilities of risk for three samples. In calculating risk, it is divided into three project acceleration assumptions, namely the assumption of a duration of 50% or 7 weeks, 40% or 6 weeks and 25% or 4 weeks from normal duration 14 weeks. Risk probability is obtained from the probability of the event and the probability of the impact. The highest loss is in 4 weeks duration (25% assumption) where has a total loss 308,638,309.40 rupiahs. The smallest loss is in normal duration 14 weeks where has a total loss 108,444,489.74 rupiahs. the relationship between probability and project acceleration is found. Where, there is an increase in the probability of a duration of 4 weeks by 0.17459% and a decrease in the probability of a normal duration of 14 weeks by 0.0618%.

Published: February 2024

Pekalongan City is a lowland area and located in the northern part of Java Island. Tidal flooding often occurred at high tide when the wave run-up entered the mainland and inundated several areas in the city of Pekalongan. The inundation area in Pekalongan City reached 618 Ha in 2020. Tidal flooding became a problem because it inundated vital areas such as residential areas, public spaces, and economic centers. The area that often experiences inundation is in the area of the Loji River and the Banger River estuarine, which is a unified system on the Pekalongan River. The inundation due to tidal flooding will be more severe if it coincided with the occurrence of high discharge in the river flow. To control floods and tidal floods in the city of Pekalongan, flood control engineering was needed so a floodway known as the Banger River was built. This approach aims to reduce the area of inundation and protect existing vital areas. This study aims to assess the impact of the Banger River on reducing water level in the Loji River. The methodology used in this study is flood modeling with HEC-RAS 6.1 one dimensional model. The simulation results show that after the Banger river floodway was made, the water level in the Loji river 1.7 meters or 28% of the water level in the Loji River can be reduced.

Published: February 2024

Landslides are disasters that can cause damage to the environment and infrastructure and disrupt community activities, especially in mountainous and hilly areas. Identifying the geometry and some physical characteristics of the landslide material is essential to determining the appropriate mitigation method. This study used electrical resistivity tomography (ERT) to investigate landslides on the spillway slope of Ciawi Dam, West Java. The identification was carried out a 2-D resistivity data along seven profiles over the landslide area using a Dipole-dipole configuration. Borehole data also supported it. Electrical resistivity tomography analysis shows that the northern part of the landslide location is dominated by the water-saturated zone and weathered rocks in the southern part. Borehole data support that the rock at the landslide location consists of tuffaceous sandstone with tuffaceous clay inserts that are moderate to highly weathered. The resistivity data from the line recorded along the axis of the landslide also indicated the failure surface.

Published: February 2024

The Sidoarjo mud volcano is a geological disaster which still erupting after 16 years located in a densely populated. The eruption of Sidoarjo mud volcano is the longest continous disaster that Indonesia has ever experienced. It is known that there is overpressure in subsurface that propagated to the surface throught faults. However, the overpressure generation leads to the increase of pore water pressure, so the effective soil stress decreases. This study aims to estimate the change of pore water pressure and effective stress on the subgrade of Sidoarjo mud volcano due to the subsurface pressure. Furthermore, this study considers the existing embankment and excess pore water pressure due to the consolidation process using Finite Element Method. The results show high active pore water pressure in these area is around -580 kPa, due to the consolidation process is -372 kPa and the contribution of subsurface pressure is -208 kPa. The anomaly of effective stress occur from a depth of -13 m to -30 m. Thus, the reduction of effective stress is around 6%-56% from the ideal conditions with the largest reduction occurred at a depth of -30 m.

Published: February 2024

Over the last few decades, significant damages have been observed in our environment. Being a densely populated country, Bangladesh has also faced significant environmental challenges over the last couple of years. To understand the pattern, researchers have analyzed land coverages in several parts of the world. This study presents an analytical study of the land coverages and land transition maps of the Rajshahi City located in Bangladesh. Our study was focused on the 1990,1998,2007,2014, and 2021 years. The maps were generated using ArcGIS 10.8 software. From our results, we observed that there was significant vegetation loss in the selected region over the years. The reduction in vegetation area is determined by a trend line of 0.8291% per year starting from 1990. Previous studies have shown that trees absorb the pollutants from the air and make the air cleaner. In this study, several graphs showing the decreasing rate of the absorption of air pollutants due to decreasing rate of vegetation are manifested. The increasing rate of air pollutants causes several life-threatening diseases and contributes to the rising temperature. To cope with this vegetation loss, we have proposed a partial solution that is rooftop gardening which supports Urban planning management with greenery.

Research on the bacteria and fungi potentially degrading microplastic in Piyungan Landfill has not been done much. Meanwhile, plastic pollution is one of many environmental problems faced in the Special Region of Yogyakarta. The accumulation of plastic waste is getting more significant daily, and the capacity of landfills is decreasing. Bacterial and fungal testing was carried out by taking soil samples from landfills and isolating dilute Nutrient Broth, Malt Extract Agar, and Nutrient Agar media. Bacterial and fungal were identified by morphology colony and cell, then tested for plastic biodegradation by selected bacterial and fungal. The result of this research, there are 18 bacterial isolate and five isolate fungi, but for the degradation testing, chosen just three bacterial (Isolate A, F, J) degrade Polypropylene for ±30 days and three fungal (Isolate PA, PK, RJ) to degrade LDPE for ±14 days. The indicator for determining plastic degradation is clear-zone formation. The test result showed that isolate F, which had similarity with bacteria in the genus of Micrococcus, had a higher potential to degrade microplastic with clear-zone formation ±1.23 mm. Meanwhile, fungal isolate PK, similar to Penicillium sp., had a higher potential to degrade microplastic, marked by the most significant clear-zone appearance, ±2.3 cm.

The Çamlıca Mosque was built in a combination of Ottoman, Seljuk and modern architectural styles. The purpose of this study is to examine the application of Ottoman, Seljuk, and Modern architectural styles to the Çamlıca Mosque and to examine the character of the components in the Çamlıca Mosque from the aspect of the yard, mihrab, minaret, dome and examines the facade, the structure of the building, and the functions of the mosque. This research is unique because it proves which architectural style stands out the most. The method used in this research is descriptive qualitative exploratory by conducting direct observations to determine the combination of Ottoman architectural style, Seljuk architectural style, and Contemporary architectural style. The results of this study can be explained that the main features of the Çamlıca Mosque still maintain the presence of the yard, mihrab, minaret, dome with other features namely Rewaqs and Iwan. The facade of the Çamlıca Mosque, especially the use of wall materials are concrete, glass, a combination of glass and wood, and contemporary marble, while the shape of the door is a combination of Seljuk, Ottoman, and contemporary architecture with floral motifs, geometry, and calligraphy. The structure of the building, especially the columns, has various shapes, sizes, colors, materials. The functions of the Çamlıca Mosque complex are only a mosque as a place of worship and a library and this is in accordance with the theory of mosque functions in Ottoman Architecture although some functions are absent. Other functions of the Çamlıca Mosque are contemporary functions, namely art galleries, art studios, indoor and outdoor play rooms, gardens, museums, and conference rooms. The conclusion of this study is that the main style that dominates the application of architecture in the Çamlıca Mosque is the contemporary style.

Published: February 2024

During the COVID-19 pandemic for more than two years, there was an acceleration in increasing LDPE household waste, especially from food packaging. The problem of plastic waste is an issue that requires more attention for reuse. Meanwhile, the urban infrastructure growth is followed by the reduction of water catchment areas, so that surface water runoff causes flooding. Responding to this, porous pavement is a solution for infrastructure development, that has a low impact on the environment. However, the fact is that porous asphalt pavement has low stability, so it is applied to low traffic loads such as pedestrian ways. To overcome this problem, a material that binds asphalt and aggregate is needed. This research aims to utilize LDPE waste to improve the performance of porous asphalt mixtures. The method used is experimental by using Marshall parameters. The results of the study with the addition of LDPE and Polyurethane obtained an increase in the value of stability by 17.35% but, decreased the value of flow by 15.18% and permeability index by 12.07%. The optimum value is adding 2% LDPE and 7.5% Polyurethane so that LDPE can be used as additional material to replace some asphalt materials in porous asphalt mixtures.

Published: February 2024

This study aims to understand the changes in management trends among global companies before and after the onset of COVID-19. To achieve this, we employed keyword and topic modeling to analyze 420 CEO messages extracted from the reports of the Fortune Global 100 largest companies. The analysis revealed a noteworthy prevalence of keywords associated with shared culture, such as face-to-face interactions and cooperation, during the initial period. In the subsequent period, we observed a higher frequency of keywords related to community-centeredness and digital trans-formation, including employee health and well-being, inequality reduction, and sustainable cities. Furthermore, we identified common topics before and after COVID-19, such as risk management and competitive advantage. However, the topics that exhibited variation were the significance of corporate leadership and the evolution of digital technologies. This study is significant in that it enables us to analyze CEO messages and deduce the trajectory of corporate management post-COVID-19.

Published: February 2024

The performance analysis of the internal/external flows around a high speed vehicle in near-space is fundamental and critical to the configuration and structure design for high speed aircraft. In this paper, the two-dimensional coupled implicit Reynolds Average Navier-Stokes (RANS) solver and RNG k–ε turbulence model is employed to numerically simulate the flow field of an integrated high speed vehicle. The flow field are divided three parts to solve separately and compared with that solved by integrated simulation. The flow field are decomposed to save computer storage and simulation time. The first part is inlet/isolator, the second part is combustion chamber and the third is nozzle. In the computation process, the outlet condition of isolator is endowed to the inlet boundary of combustion chamber and the outlet boundary of combustion chamber is endowed to the inlet boundary of nozzle, then the whole flow field of integrated high speed vehicle is solved. Aerodynamic characteristic of fragment-computation and integration-computation is comparatively analyzed at different angles of attack, the results show that the maximum deviation of lift coefficient obtained by fragment-computation is less than 3% compared with that by integration, the maximum deviation of drag coefficient fragment-computation is less than 5% compared with that by integration, while pitching moment coefficient deviation less than 12%. However, for simulation time-consumption, the time used by fragment-computation reduces 45% compared with integration-computation. Meanwhile, by components force analysis, it can be concluded that the aerodynamic property of inlet/isolator can been obtained separately and hardly effected by other parts.
Exploring Sustainability through existing and potential GIAHS (Globally Important Agricultural Heritage Systems)
Authors: Yadav Keerti , Jin Jongheon
Published: February 2024

Social, environmental and economic problems are the concern in the agroecological communities. To address these issues, it is important to understand how communities think and act towards existing sustainable practices. There are various agriculture practices which are aboriginal to particular region, and have the knowledge of environment in deep sense thus, locals utilize it for coexisting with nature, by preserving environment and fulfilling the human needs for food alongside protecting the disappearing practices. At present, India has only three designated GIAHS sites and no proposed sites at present, despite having a diverse physical environment and area. Therefore, this paper acknowledges the need to recognize potential indigenous agricultural heritage site as GIAHS and its multidimensional Sustainability and vulnerability by climate change, Traditional value, ecological value, socio cultural values and value-added behavior which can increase the economic value and appeal towards agricultural commodities in later phase. Therefore, this paper aims to investigate the potential AHS site in the north east region of India, which is known as Zabö or Ruza and changes in the LULC of the area. Alongside assessing the present agricultural Heritage systems and changes GIAHS recognition brought to it.
Advancing Crisis Translation And Interpreting: The Design Of The Multilingual Smartphone Application CTermPort For Crisis Settings
Authors: KARAMAN Burcu İlkay
Published: February 2024

Feedback from the earthquake zone in Kahramanmaraş, Turkey has established that the emerging field of Crisis Translation and Interpreting (CTInt) requires a free smartphone application, to enable Crisis Translators and Interpreters (CTIs) to access multilingual terminology resources on-/offline when assisting Search and Rescue (SAR) teams responding to man-made and/or natural disasters.The aim is to design not only a multilingual compilation of Crisis Terminology (CTerm), downloadable to smartphones enabling access when there is a failure in the internet connection, but also a unified search tool which will browse and redirect the user to existing termbanks when the internet is accessible. Nevertheless, terminological records available in the domain of CTerm are inadequate and dispersed, with different interfaces and language combinations, requiring enhancement and harmonisation. Furthermore, automated translation and interpreting software/systems supported by the multilingual compilation of the crisis terminology portal (CTermPort) ideally need to be developed or, alternatively, existing ones integrated into the crisis termbank (CTermBank) collection for those who would lack the support of CTIs.The design of the CTermPort will significantly impact civil societies by providing a lifesaving tool for CTIs who need a reliable terminological reference point and automated translation options, and those unable to be assisted. In this respect, the project also promises strong prospects of sustainability past the project duration, as the tool to be developed will serve international SAR teams working closely with CInts during response times, but also medical staff in field hospitals collaborating with CTIs in rehabilitation and recovery phases, and beyond.
Contention in Carbon Accounting in the Digital Industry: The Need to Move towards Decision-Making in Uncertainty
Authors: Samuel Gabrielle , Lucivero Federica , Knowles Bran , Wright Katherine
Published: February 2024

In this paper, we present findings from a qualitative interview study, which highlights the difficulties and challenges with quantifying carbon emissions, and discusses how to move productively through these challenges by drawing insights from studies of deep uncertainty. Our research study focuses on the digital sector and was governed by the research question: how do practitioners researching, working or immersed in the broad area of sustainable digitisation (researchers, industry, NGOs, and policy representatives) understand and engage with quantifying carbon? Our findings show how stakeholders struggled to measure carbon emissions across complex systems, the lack of standardisation to assist with this, and how these challenges led stakeholders to call for more data to address this uncertainty. We argue that calls for more data to address this uncertainty obscure the fact that there will always be uncertainty, and that we must learn to govern from within it.

The study employed a longitudinal approach, collecting Facebook data from adult users over a 12-month period using the Graph API. Data were divided into 12 monthly segments. Two monthly indicators were calculated: the percentage of textual status updates and the average number of Likes per post. Current and perceived changes in Quality of Life (QoL) were administered as self-report measures. The findings indicated a positive correlation between the frequency of textual Facebook posts and the average received Likes. Furthermore, receivign more Likes was positively associated with a higher current QoL, and perceived improvements in QoL correlated with an increase in Likes over time. The study suggests that online positive social feedback, measured through Likes on Facebook, is associated with both current QoL and perceived improvements in QoL among adult Facebook users. This highlights the potential impact of online social interactions on individual well-being.

Food allergies are common worldwide and have become a major public health concern; more than 220 million people are estimated to suffer from food allergies worldwide. On the other hand, polyphenols, phenolic substances found in plants, have attracted attention for their health-promoting functions, including their anti-allergic effects. In this study, we examined the potential inhibitory effects of 80% ethanol extracts from 22 different vegetables on the degranulation process in RBL-2H3 cells. Our aim was to identify vegetables that could prevent and treat type I allergic diseases. We found strong inhibition of degranulation by the extracts of perilla and chives. Furthermore, we verified the respective efficacy via animal experiments, which revealed that the anaphylactic symptoms caused by ovalbumin (OVA) load were alleviated in OVA allergy model mice that ingested vegetable extracts of perilla and chives. These phenomena were suggested to be caused by induction of suppression in the expression of subunits that constitute the high-affinity IgE receptor, particularly the α-chain of FcεR I. Notably, the anti-allergic effects of vegetables that can be consumed daily are expected to result in the discovery of new anti-immediate allergenic drugs based on the components of these vegetables.

This research aims to evaluate the implementation of industrial class-based experiential learning in Vocational High Schools (SMK) and its impact on increasing student competency, which is considered crucial in facing the challenges of industrial development in Indonesia. This learning approach is expected to provide an authentic and relevant learning experience to the needs of the world of work, proven to increase students' motivation, learning outcomes and practical skills in various subjects through a literature review. However, the high unemployment rate of vocational school graduates and the lack of connection between the school curriculum and industrial demands show the urgency of developing learning models that better integrate education with industrial needs. The Systematic Literature Review (SLR) method was used to analyze ten related previous studies, showing that the experiential learning model had a positive impact on learning motivation and learning outcomes of vocational school students. However, research highlights the limitations of implementing industry-based experiential learning for it requires collaboration between schools, government and industry. Involving industry in the learning process is expected to provide students with direct experience, increasing their readiness to enter the world of work. This research contributes to detailing the benefits of industrial class-based experiential learning in vocational schools and highlights the need for increased implementation of this model. The findings of this research are the basis for further research and efforts to develop vocational education in Indonesia.

The need for the development of instruments for higher-order thinking skills of vocational students related to the demands of the era and the lack of teachers’s capability on arrange it requires a strengthening in the learning evaluation process, especially in measuring the ability of students. SMK in building competence focuses on creating superior human resources to be ready to contribute to the civil sector. Along with the rapid development of the construction world, competitiveness to work in this field has become tight so that graduates must have a differentiator that can be a special attraction to the company. In SMK of building competence, the subject that require an understanding of concepts in solving problems is techincal- mechanical subject. This subject is knowing as a subject that applies derived concepts of mathematics, physics, and logical thinking. This study was conducted as an effort to support the improvement of these capabilities and provide an overview of the preparation of HOTS-based techincal-mechanial instruments in building engineering. This research used Research and Development Methods using the Classical Test Theory approach where after being tested on 574 respondents of vocational school students in several areas in Jakarta it was found that the reliability results were good, and most of the questions had a medium level of difficulty, and high differentiation.

Eficacia clínica del ácido hialurónico en el tratamiento del defecto intraóseo periodontal: una revisión sistemática y meta-análisis
Authors:   , Ostos Aguilar Bertha Ines
Published: February 2024

Objetivo: Esta revisión sistemática tuvo como objetivo evaluar los efectos del ácido hialurónico (AH) solo o en combinación con cualquier sustituto óseo para el tratamiento de los defectos intraóseos (DIO). Material y métodos: Se realizaron búsquedas en seis bases de datos hasta abril de 2022 para encontrar ensayos clínicos aleatorizados que compararán los efectos clínicos del desbridamiento con colgajo abierto (DCA)+AH frente al DCA solo (primer grupo) o DCA+AH + sustitutos óseos frente a DCA + sustitutos óseos (segundo grupo) en el tratamiento de los DIO con un seguimiento de al menos 3 meses. Se utilizaron modelos de efectos aleatorios de diferencias medias para determinar la ganancia del nivel de inserción clínica (NIC), la reducción de la profundidad de sondaje (PS) y el relleno óseo radiográfico (ROR). Resultados: De los 276 estudios identificados, 6 se incluyeron en la síntesis cualitativa y 5 en los metaanálisis. Los metaanálisis del primer grupo mostraron diferencias estadísticamente significativas en la ganancia del NIC (diferencia media [DM]: 1,00; intervalo de confianza [IC] del 95%: 0,65-1,35; n = 2) y la reducción de la PS (DM: 0,76; IC del 95%: 0,34-1,17; n = 2) a favor de AH+DCA a los 6 meses. Sin embargo, en el segundo grupo, los metaanálisis no demostraron un efecto adicional del AH en asociación con el sustituto óseo ni para la ganancia del NIC (DM: 0,57; IC del 95%: -0,30-1,43; n = 2) ni para la reducción de la PS (DM: 1,05; IC del 95%: -0,38-2,47; n = 2), pero sí mostraron diferencias significativas para el ROR (DM: 0,57; IC del 95%: 0,15-0,99; n = 2) a los 12 meses. Conclusiones: En comparación con el DCA solo, la aplicación local de AH en el tratamiento de los DIO proporcionó una ganancia significativa del NIC y una reducción de la PS a los 6 meses. Sin embargo, su combinación con sustitutos óseos no mostró diferencias estadísticamente significativas a los 12 meses. Importancia clínica: El uso de DCA+AH mejora el NIC y la PS en el tratamiento de los DIO en comparación con DCA sólo tras 6 meses de seguimiento. Estos resultados no se mantienen a los 12 meses.
