Authors: Kotlarek Katelyn J. , Rogers Katelan , Mason Kazlin N.
Published: December 2023

Purpose:

The purpose of this study was to identify training gaps and continuing education (CE) needs for speech-language pathologists (SLPs) in evaluating and treating children with cleft palate across and among areas of varying population density.

Method:

An anonymous 35-question survey lasting approximately 10–15 min was created in Qualtrics based on a previously published study. The survey information and link were electronically distributed to American Speech-Language-Hearing Association (ASHA)–certified SLPs through ASHA listservs, social media, individual-state SLP organizations, and an e-mail list of publicly listed SLPs. A total of 359 survey responses were collected.

Results:

Respondents varied in terms of age, type of certification, practice location, and clinical experience with cleft palate, with the largest percentage (46.7%) of respondents in a school-based setting. Only 28.5% reported currently feeling comfortable treating children with cleft palate. Respondents reported conventions/conferences (25.4%) and webinars (23.2%) were the most helpful resources, but DVDs were frequently not used for CE. Information from the child's cleft team (84.4%) and mentors/colleagues (70%) were considered high-quality resources. Respondents indicated information on treatment of articulation (79.2%) and resonance (78.4%) disorders as well as specific therapy techniques (76.9%) would be very helpful for clinical practice. Population density significantly influenced how respondents ranked the perceived helpfulness and quality of different resources as well as desired topics for future resources.

Conclusions:

There is a continued need for adequate training and CE opportunities for SLPs, particularly related to assessing and treating children with cleft palate. Increased access to high-quality CE resources will be key to filling educational gaps present for SLPs, especially in areas of low-population density.

Nuclear facilities have a regulatory requirement to measure radiation levels within Post Operational Clean Out (POCO) around nuclear facilities each year, resulting in a trend towards robotic deployments to gain an improved understanding during nuclear decommissioning phases. The UK Nuclear Decommissioning Authority supports the view that human‐in‐the‐loop (HITL) robotic deployments are a solution to improve procedures and reduce risks within radiation characterisation of nuclear sites. The authors present a novel implementation of a Cyber‐Physical System (CPS) deployed in an analogue nuclear environment, comprised of a multi‐robot (MR) team coordinated by a HITL operator through a digital twin interface. The development of the CPS created efficient partnerships across systems including robots, digital systems and human. This was presented as a multi‐staged mission within an inspection scenario for the heterogeneous Symbiotic Multi‐Robot Fleet (SMuRF). Symbiotic interactions were achieved across the SMuRF where robots utilised automated collaborative governance to work together, where a single robot would face challenges in full characterisation of radiation. Key contributions include the demonstration of symbiotic autonomy and query‐based learning of an autonomous mission supporting scalable autonomy and autonomy as a service. The coordination of the CPS was a success and displayed further challenges and improvements related to future MR fleets.
Joint optimization of reconfiguration and traffic planning in time‐triggered networks
Authors: Li Ji , Li Qiao , Xiong Huagang
Published: December 2023

The existing research on time‐triggered network reconfiguration neglects redundant traffic states, posing a challenge in effectively balancing traffic performance and reconfiguration efficiency in practical deployments. In response to these limitations, a novel joint optimization approach is introduced for reconfiguration and traffic planning. Initially, the efficiency of reconfiguration solutions is enhanced by sacrificing the delay performance of redundant flows and prioritizing compressed yet tailored constraints. Subsequently, a tabu‐based optimization algorithm is employed to provide more flexible enhancements to the delay performance of network‐wide traffic. The outcomes demonstrate that the proposed method significantly outperforms incremental reconfiguration, improving the solution efficiency of the reconfiguration recovery phase by over 75.38%. Furthermore, through multiple rounds of reconfiguration, the approach achieves an 8.38% improvement in the average delay performance of all flows, even with redundant flows sacrificed.

Published: December 2023

Purpose The diagnosis of peripheral nerve injuries remains challenging. Electromyography and nerve conduction studies do not allow precise localization of the lesion and differentiation between lesions in continuity and non-continuity in cases with complete axonotmesis. Improved ultrasound technology allows the examination of almost the entire peripheral nervous system. The complex sono-anatomy of the brachial plexus outside of the standard scanning planes makes it difficult to access this region.

Methods On the basis of the Visible Human Project of the National Institutes of Health (NIH), multiplanar reconstructions were created with the 3D Slicer open-source software in the various planes of the ultrasound cross-sections. The ultrasound examination itself and the guidance of the ultrasound probe in relation to the patient were recorded as video files and were synchronized through the audio channel. Subsequently, image matching was performed.

Results Multiplanar reconstructions facilitate visualization of anatomical regions which are challenging to access thereby enabling physicians to evaluate the course of the peripheral nerve of interest in dynamic conditions. Sonographically visible structures could be reproducibly identified in single-frame analysis.

Conclusion With precise knowledge of the ultrasound anatomy, the nerve structures of the brachial plexus can also be dynamically assessed almost in their entire course. An instructional video on ultrasound of the brachial plexus supplements this manuscript and has been published on Vimeo.com.

Authors: Xu Chongxi , He Wenbo , Yi Tong , Zhang Hongtian , Xu Jianguo , Ma Junpeng
Published: December 2023

Background There is still no consensus on whether primary pontine hemorrhage (PPH) should be managed conservatively or treated promptly via surgical evacuation of the hematoma. The purpose of this study was to assess the therapeutic effect of robotic frameless stereotactic aspiration with thrombolysis in the treatment of PPH.

Methods A total of 39 patients with PPH treated between January 2012 and November 2016 were included in the study. Sixteen patients underwent frameless stereotactic surgical treatment (ST group) and 23 patients underwent conservative treatment (CT group). Clinical and radiologic parameters were assessed, and the patient outcomes were analyzed over a 6-month follow-up period.

Results Surgical treatment did not result in any intracranial infections, or complications. Baseline characteristics did not significantly differ between the two groups. At discharge, the average Glasgow Coma Scale (GCS) score and the overall Glasgow Outcome Scale (GOS) score were significantly higher in the ST group compared to the CT group (p < 0.05). The mortality rate (GOS score 1) was significantly lower in the ST group (18.75%, 3/16) than in the CT group (52.17%, 12/23). For patients with hematoma volumes of 5 to 10 mL or GCS scores of 6 to 8, following treatment, the ST group exhibited markedly higher GOS scores in comparison to the CT group.

Conclusion Our study suggests that robotic frameless stereotactic aspiration with thrombolysis is a safe and efficient method for the treatment of PPH. Patients with hematomas of 5 to 10 mL or GCS scores of 6 to 8 could benefit from surgery.

Published: December 2023

Objectives The aim of this study was to determine oral problems and attitude of dental patients toward the effect of the COVID-19 pandemic in Thailand.

Materials and Methods This cross-sectional study used a questionnaire consisting of four parts: demographic data, oral health problems before and during the COVID-19 outbreak, daily behavior and oral hygiene care during the pandemic, and attitudes toward the effects of COVID-19 situations and oral health problems in Thailand. It is randomly distributed to the dental patients at the Faculty of Dentistry, Mahidol University.

Statistical Analysis Descriptive statistics and Pearson's chi-squared test were used to determine the correlation between each individual demographic data and the attitudes toward the COVID-19 effect. McNemar's test was used to examine the association between oral problem before and during the pandemic.

Results Among the total of 409 participants, 59.9% believed that the COVID-19 situation impacted their oral health. The fractions are 64.6 and 50.7% for females and males, respectively. Halitosis and gum bleeding showed significant increase during the pandemic from 9.3 to 15.4% and 5.9 to 10.3%, respectively. Unchanged tooth brushing habit was reported in 86.3% of respondents, while only 44.6% reported unchanged consumption of sugary snacks and/or beverages. COVID-19 caused more difficulty in accessing the dental service for 89.5% of respondents. The majority of the participants were not worried about their safety while receiving dental treatment after the pandemic, but they believed that the pandemic influenced their decision to seek dental treatment.

Conclusion Inadequate oral hygiene appears to be the main reason for the increase in cases of halitosis and gum bleeding during the pandemic. Viral infection preventive measures and protocols greatly affected the patients' decision to visit a dentist. This information could serve as a primary reference for both dentists and administrators in preparing actions in case a similar pandemic occurs in the future.

Authors: Singh Aman , Yadav Awadhesh , Yadav Pritesh , Ojha Bal Krishna
Published: December 2023

Ventriculoperitoneal shunt is one of the commonest neurosurgical procedures associated with a high-rate complication. Moreover, the variety of complications are nonetheless astonishing. Shunt malfunction is considered the most common complication of this procedure, but a cranial migration of shunt leading to malfunction is extremely rare. We present a case of a 6-month-old male child who was initially managed with a right-sided medium-pressure ventriculoperitoneal shunt for aqueductal stenosis with hydrocephalus at the age of 3 months and presented to us with features of shunt malfunction owing to a cranial migration of the shunt assembly. Cranial migration of a ventriculoperitoneal shunt is an extremely rare complication. Its possible mechanism includes a large subgaleal space for the chamber, larger size burr hole, inadequate anchorage of the shunt assembly, and excessive neck movements of the child in the postoperative procedure.

Published: December 2023

The indirect measurement method of extracting the dynamic characteristics of the bridge structure from the dynamic response of passing vehicles is a new method for bridge structure health monitoring, which has the advantage of cost-effectiveness. However, how to improve the accuracy of the indirect measurement method to identify the dynamic characteristics of the bridge is the current research focus. In this paper, combining the characteristics and advantages of bandpass filter (BPF) and wavelet transform (WT), a simple and effective joint filtering method BPF-WT is proposed for indirect identification of bridge dynamic characteristics. This method can eliminate the peak caused by the known vehicle frequency, and realize the layer-by-layer decomposition and reconstruction of the signal through the advantage of WT, to achieve the purpose of automatically executing the packet filtering task. This paper takes a simple trolley as an example to conduct a scaled test study to identify the dynamic characteristics of a bridge and proves that the BPF-WT joint filtering method can perform bridge dynamics under three conditions: different vehicle weights, different driving speeds, and driving on bridge decks with different roughness. Characteristic identification results and their influence rules. According to the research findings, the method of combined filtering suggested in this paper can efficiently filter out the noise produced by the vehicle’s frequency and the surroundings. This method can also distinctly detect the initial three frequencies of the bridge. Therefore, it demonstrates the practicality and efficiency of the BPF-WT combined filtering technique, which has a broad range of potential applications.

Published: December 2023

Metal additive manufacturing has gained popularity due to its significant advancement in minimising waste. The product design using additive manufacturing (AM) does not require mould and less material required, which is less waste. In this way, AM has the potential to transform the manufacturing industries towards greater sustainability. Besides, AM allow more complex designs and shape than conventional manufacturing. Wire arc additive manufacturing (WAAM) is one of the most popular metal AM that has received significant attention due to its usefulness for localising, repairing, and modifying instead of discarding and replacing entire components. However, conventional welding technology faced the issue of significant heat input, low surface quality, and low dimensional accuracy of WAAM components. Micro-plasma arc welding (MPAW) is a new alternative to the WAAM process. The speciality of MPAW is low current provided of 1A to 25A current range, leading to low heat input and energy-efficient manufacturing. The present study shows various metallic structures developed using an MPAW-based WAAM system, and the relative error between the CAD model and four different structures was determined. Overall, the study outcome shows the geometric uniformity of parts produced with an MPAW-based WAAM system and demonstrates smooth surface finish can be obtained.

Municipal solid waste (MSW) disposal has emerged as a major concern in large cities across Indonesia. Waste-to-energy (WtE) incineration is an attractive method that can significantly reduce volume of waste; however it generates residues, namely bottom ash and fly ash. This study presents the characteristics of bottom ash from the MSW WtE incineration pilot plant in Indonesia. The physicochemical characterization of bottom ash was determined X-ray fluorescence (XRF) and scanning electron microscopy-energy dispersive spectrometry (SEM-EDS). The results showed that CaO (46.80%) was the major component, followed by SiO2 (12.30%), Al2O3 (8.80%), and Fe2O3 (8.20%). SEM images showed that the surface morphology of bottom ash appeared flaky, rod-like, and irregular shape. Inert materials, like iron scrap, glass, ceramic, and stone, accounted for 16.7% of the total dry weight of bottom ash. Toxicity characteristic leaching procedure (TCLP) test of 11 heavy metals in bottom ash was carried out, and all of them were detected at very low concentration, indicating that bottom ash possessed a low risk level to human health and environment. This study provides important information on the characteristics of bottom ash from MSW WtE incineration in Indonesia that would be useful in facilitating management and disposal of bottom ash.

Currently, water is a product of economic value because groundwater scarcity is starting to occur everywhere. Improving water quality and efficiency is one of the targets in the sustainable development goals (SDGs). Generally, the batik-making process by Small and Medium Enterprises (SMEs) uses groundwater in the process. It will cause negative environmental impacts. This research examines the water footprint of batik-making SMEs in Laweyan, Surakarta City, Indonesia, which use combination methods and synthetic dyes. Direct groundwater use for making batik cloth resulted a blue water footprint of 1.38 L/m2. Simultaneously, the grey water footprint is calculated by calculating the water needed to dilute COD from production, resulting in a value of 14.60 L/m2. The results showed that the water footprint of the batik-making process requires 15.94 L/m2 of water. The 1st washing requires more water than the other production stages. Reducing the water footprint in the batik industry can be done through proper management of water resources so that not only conserves water for humans and the ecosystem but also preserves batik as a cultural heritage.

Published: December 2023

The use of paper as a media for product promotion is still widely used by companies in introducing their products. Promotional media used include brochures and flyers which are indeed printed to be distributed to potential customers. This way of promotion has an impact on the large number of paper-based promotional media which are then discarded after viewing. As it is known that paper comes from trees, currently, there are many environmental problems originating from illegal logging of forest trees and deforestation, which have an impact on ecosystems and the natural environment. During the current use of technology, the use of product introduction promotional media can use Augmented Reality (AR) technology. With AR, potential consumers can see 3D objects from products being marketed so that paper use can be reduced. In building AR, we use Game Engine Unity and Vuforia to be able to display 3-dimensional objects. This research is also based on Android as the base of the operating system. For the case study, we use four furniture products such as tables, chairs, and sofas as a subject of implementation. The purpose of this research is to reduce the use of paper as a medium for product promotion. The results of the research are in the form of media applications for promotion of Augmented Reality-based furniture products. Testing uses black box testing to test the performance of the AR along with testing various marker conditions, such as in low light and high light condition.

Published: December 2023

Conversion technology will continue to evolve. These developments started from the industrial revolution 1.0 to the industrial revolution 4.0, but in these developments even though technology solves a problem, it has the potential to cause new problems such as environmental problems. Environmental problems that can occur starting from energy conversion that is not environmentally friendly as well as the use of several technologies that cause pollutants that are quite dangerous if high intensity can even cause health problems, acid rain and climate change. The pyrolysis process has been proven capable of converting municipal solid waste (SPP) into bio-oil (BO) where most of the BO produced is hydrocarbon fuel with light oil (naphtha) and diesel types. Many studies have been carried out by various groups, but the raw materials used are single SPP components such as plastic, biomass, tire rubber, paper and not the real SPP. Therefore, this research was conducted to see the effect of using variations in zeolite catalyst concentration on the bio-oil produced. Variations in zeolite catalyst concentration are divided into concentrations of 0.25; 0.5; 0.75 and 1. For the pyrolysis test, it was carried out at a temperature of 400 ° C, with a reaction time of 60 minutes. From the results of experiments that have been carried out, the most ideal concentration for producing the most bio-oil products is at a concentration of 0.5. This indicates that the more catalysts are used in the pyrolysis process, the more syngas products will be produced. So the use of catalysts in the pyrolysis process can increase thermal efficiency and the pyrolysis process can be carried out at low temperatures for the production of bio-oil from mixed waste. If following national oil needs and these reserves continue to be exploited, Indonesia will only have oil reserves for the next 7-8 years or until 2028. Another problem is that the use of conventional fuel oil will produce large amounts of CO2 and will make a major contribution to climate change and global warming.

The isotherms and kinetic adsorption models for lead (II) in the mining pit water at Bangka on Shrimp Shells Waste Chitosan (Sw-Chi) was studied. The Sw-Chi from the dried shrimp (generallyPenaeus semisulcatusspecies) waste were extracted via deproteinization, demineralization, decolorization and deacetylation steps at previous work. The chitin deacetylation values of Sw-Chi was 88.98% determined through FTIR spectra using baseline method. The initial lead (Pb (II)) concentration in this study was 0.41 ppm from open-pit water in Sungailiat district, Bangka Island. The performance of Sw-Chi adsorption on lead in the pit water with the ratio of 1:500 (w/v) in variation contact time while stirring at room temperature. The adsorption isotherms and kinetic models for lead in the mining pit water at Bangka follows the pseudo-second-order (PSO) and the Freundlich isotherm (F-Isoth) model. The adsorption mechanism may be due to Van der Waals forces and formed lead multilayer onto Sw-Chi surfaces.

Batik Cual is one of the archipelago’s traditions in Bangka Belitung Province. As the production of cual batik cloth increases, it is accompanied by an increase in production waste of liquid waste. Cual batik waste contains remasol dye which is carcinogenic. Therefore, proper and safe waste management for the surrounding environment is needed. Electrocoagulation is a method without chemicals in the coagulation process and is able to reduce turbidity and color parameters. The various types of plates (aluminium, copper, and zinc) used in the electrocoagulation process aim to determine the level of improvement in the quality of cual batik wastewater before and after the electrocoagulation process. The test results show that the level of improvement in waste quality for the level of turbidity, color, and pH occurs in copper type plates.

The use of local natural materials as alternative materials in road construction could save construction costs, especially for Maluku Province. One of the local natural materials in Maluku Province is Limestone in Kelan Village and Kaliobar Village. Therefore, this study aims to see how far the use of limestone to be applied as a cement treated base material. Before being applied, the limestone is tested first in the laboratory. After the limestone was applied as a cement treated base (CTB) material, compaction and compressive strength tests were carried out. The number of CTB compressive strength test specimens was 26 samples from STA 4+100 to STA 8+900. The limestone on Larat Island is unique in that it contains the composition CaCO3 (Calcium Carbonate), which is the result of shallow sea sedimentation. The potential of limestone in the work location area has not been utilized optimally to improve the economic level of the community. The test results show that the compressive strength values obtained are still within the interval range, namely between 25 - 40 gr/cm2. Therefore, it can be concluded that the CTB mixture material at this location meets the requirements to be used as a foundation layer for road pavement using local natural materials.

Castor (Ricinus communis) plants have been cultivated. Castor oil has been cultivated and has become one of the world’s major commodities, with the leading producer being India. Castor oil’s primary products and derivatives include Hydrogenated Castor Oil (HCO), polymers, lubricants, and biodiesel. Conventional extraction is usually done using a machine or hot water extraction methods. In large industries, extraction is carried out to obtain high purity with the help of solvents. Organic solvents are suitable for extraction, such as methanol, ethanol, and n-hexane, which are the most commonly used. This research aims to obtain techno-economic feasibility through a simulation of castor oil production using SuperPro Designer version 13.0. The extraction process is carried out in two stages: mechanical extraction followed by water degumming, neutralization, and adsorption with activated carbon. Production capacity and technology used are adjusted to existing companies and literature. From the results of the economic analysis, this production process is feasible with an IRR of 32.11%, a PBP of 3.25 years, and a BC Ratio of 1.05.

Geoid modeling requires accurate and evenly distributed gravity data throughout the study area. Although airborne gravity measurements are getting more massive, some areas are politically restricted areas. Therefore, terrestrial measurements are still needed, such as in Bekasi City and its surroundings. In terrestrial geoid modeling, ideal conditions are often difficult to achieve, because terrestrial measurements can only be made in accessible, safe, and permitted places. These non-ideal conditions result in an uneven distribution of data which can decrease in the accuracy of the resulting geoid. One way to overcome this data acquisition problem is to fill in the data using synthetic data calculated from the global geopotential model data. This study aimed to analyze the effect of using EGM data on geoid accuracy. The data needed for this research were terrestrial gravity data, EGM2008, and SRTM30 Plus, and GEBCO. The geoid was calculated using several calculation modules from Gravsoft. Specific modifications were made using Simply Fortran to facilitate geoid modelling with integral of Hotine. This research was conducted with two scenarios, namely geoid calculations using only terrestrial gravity data and geoid calculations using a combination of terrestrial data and EGM2008. The accuracy of the geoid was analyzed based on the magnitude of the deviation between the local Bekasi geoid and the national geoid represented by INAGEOID2020 2020 version 2. Free Air gravity anomaly provide by Badan Informasi Geospasial were converted to be gravity disturbance data on the earth’s surface. The secondary data gravity disturbance was calculated from EGM2008 with n=360 and n=2190. The geoid calculated from terrestrial geoid data alone produced the largest offset to the national geoid. Combination of terrestrial gravity data and generated data from EGM2008 n=360 performed higher precision geoid.
