Manufaktur Dan Pemasangan Komponen Avionik Pada UAV Skywalker 1900 Dengan Material Komposit Berpenguat Fiber Carbon

This research is a collaboration between STTKD Yogyakata and Frogs Indonesia, a startup that manufactures flying vehicles, with the aim of making the UAV Skywalker 1900 flying vehicle with Carbon Fiber reinforced composite materials to produce a structure that is stronger than the material commonly used, namely Styrofoam. The initial stage of making the UAV was to work on the Skywalker 1900 UAV design drawings and printed them with 3D printing using PLA Filament, the 3D printing results were then molded using Epoxy resin. From the resulting molding, the structure of the aircraft parts will be made with fiber glass reinforced composite materials using the Vacuum Bagging method. After the structure of the aircraft parts is completed, the electrical and avionic components are installed. The flight test results of the Skywalker 1900 UAV aircraft have a speed of around 15 m/s to 20 m/s, the weakness of this aircraft design is that it is still difficult to control, from the existing analysis this is caused by the aerofoil on the horizontal stabilizer causing lift in the tail of the aircraft of 1 newtons.

Adherence to COVID-19 protocols: A comparative study of public and private hospitals in Ghana

ObjectiveThis study aimed to comparatively examine how public and private hospitals adhered to the COVID-19 safety protocols, and the factors associated with, and barriers to adherence in Ghana. Study designA case study design drawing on quantitative and qualitative methods to determine adherence to, and barrier of adherence to the COVID-19 protocols. MethodA sample of 283 staff participated in the quantitative study, while in-depth interviews were conducted among management staff across the public and private hospitals. Data were analyzed using descriptive statistics, independent t-test to compare differences in adherence and logistic regression model to identify the factors associated with adherence to the COVID-19 protocols. ResultsThe regression results showed that adherence to the COVID-19 protocols in public and private hospitals were significantly associated with staff training on adherence in public (OR = 2.08; p < 0.01) and private (OR = 1.44; p < 0.05), and knowledge on adherence in public (OR = 3.12; p < 0.01) and private (OR = 11.45; p < 0.01) hospitals. Adherence to the protocol varied significantly between public and private hospitals (0.001 > p < 0.05), with an effect size ranging from small to large. Clients’ behavioural factors and poor stocking of PPEs due to financial challenges were reported as barriers to adherence in both hospital types. ConclusionAdherence to the COVID-19 protocols was more pronounced in public hospitals than private hospitals suggesting the need for interventions targeting the latter to promote client and staff safety.

Exploring Multiple Identities in Barack Obama’s Speeches to the African and Arab Audience

Presidential speeches aside, being a type of political discourse is a viable expression of the different types of identities purposively constructed and negotiated to achieve intended communicative outcomes. Using two Barack Obama's speeches to the Arab and African communities, the study seeks to investigate how political actors construct their identities to a wider audience. Using an eclectic theoretical dimension of Stance Taking, Audience Design Theory and drawing insights from Discourse Pragmatics, the study notes that the discursive features of intertextuality, metaphor, rhetorical questions, pronouns, if conditionals, multiple audience, epistemic stance are deliberately deployed to reveal their individual, social, national, and racial identities of political actors to achieve both self and communal positionings. The study concludes that identity is consciously deployed in every form of language used to show both alignment and distinctiveness.

3D-printed Ag–AgCl electrodes for laboratory measurements of self-potential

Abstract. This paper details the design, development, and evaluation of a 3D-printed rechargeable Ag–AgCl electrode to measure self-potential (SP) in laboratory experiments. The challenge was to make a small, cheap, robust, and stable electrode that could be used in a wide range of applications. The new electrodes are shown to offer comparable performance to custom-machined laboratory standards, and the inclusion of 3D printing (fused filament fabrication or FFF and stereolithography or SLA) makes them more versatile and significantly less expensive – of the order of ×40 to ×75 cost reduction – to construct than laboratory standards. The devices are demonstrated in both low-pressure experiments using bead packs and high-pressure experiments using natural rock samples. Designs are included for both male and female connections to laboratory equipment. We report design drawings, practical advice for electrode printing and assembly, and printable 3D design files to facilitate wide uptake.

STUDY ON AUTOMATIC REGISTRATION METHOD OF SOURCE DATA FOR CIM BUILDING MODEL CONSTRUCTION

Abstract. The City Information Model (CIM) is a digital model designed to describe, analyze, and manage urban spatial information. It integrates various urban elements, providing decision support for urban planning, design, and management. This study focuses on the construction of building models in CIM, particularly the issue of automatic registration of source data. We propose an automatic registration method based on DWG-format architectural design drawings and SHAPE-format remote sensing building outline information. This method extracts the axis line information of the building from the plan design drawings, indirectly obtains feature points, and selects registration base points, thereby achieving the registration of real estate subdivision data. Meanwhile, by automatically fitting the outer bounding rectangle of the building and dynamically adjusting the angle, this study realizes the automatic registration of the aligned multilayer real estate subdivision data with the building outline data obtained from remote sensing images. This research provides an effective method for the automatic and batch accurate alignment of data for the construction of CIM building models, thereby enhancing the precision and reliability of the modeling.

DEVELOPING A MULTIMODAL DATABASE OF DIGITAL ARCHIVES FOR CULTURAL HERITAGE SITES – A CASE OF DIGITALLY PRESERVING THE BOROBUDUR TEMPLE OF INDONESIA

Abstract. Digital archives that support the three-dimensional (3D) digitization of cultural heritage sites are gaining popularity and attracting enormous interest as a critical strategy for digital preservation. This paper investigates the construction of a multimodal database for cultural heritage sites, which aims to preserve 3D data, images, videos and other materials along with multilingual text data. 3D scanning is widely used for efficient and accurate digitization of cultural heritages. However, some sites have been damaged entirely or partially, or sometimes, it is impossible to conduct 3D scanning of a portion of a site that is hidden from sight. At the Borobudur temple, a UNESCO World Heritage site, there are buried reliefs that are hidden at the basement and inaccessible for 3D scanning. Currently available data for these inaccessible portions of the site include old photos, computer-aided design (CAD) drawings and historical written descriptions. To digitally reconstruct 3D models of hidden parts, we introduce a method that use a single monocular photo. We constructed “Borobudur Visual Archives” to store, access, view and retrieve Borobudur-related digital assets, including the 3D data that we created.

Research on key process parameters and characteristic vibration of steam turbine shafting

Steam turbines are a major source of vibration and noise when submarines are working. How to improve the technological level of steam turbines and reduce the vibration generated by them so that submarines can achieve the purpose of acoustic stealth has always been a hot topic of research. However, blindly improving the overall technological level of steam turbines will not only increase the manufacturing cost but also prolong the manufacturing cycle of submarines. Therefore, this paper makes a reasonable model of each type of process parameter for a certain type of steam turbine design drawings for ships. Subsequently, a dynamic model of the steam turbine shafting based on the transfer matrix was established, and experiments were designed on five groups of design parameters with strong vibration sensitivity of the steam turbine shafting. The vibration response calculation under multiple process parameters of the steam turbine shafting was carried out in combination with the two. The connection between the key process parameters of the steam turbine shafting and the characteristic vibration was established, and the influence mechanism of the key process parameters of the steam turbine shafting on the characteristic vibration was analyzed.

Design and implementation of the hospital airway resuscitation trial

Guidelines for the management of in-hospital cardiac arrest resuscitation are often drawn from evidence generated in out-of-hospital cardiac arrest populations and applied to the in-hospital setting. Approach to airway management during resuscitation is one example of this phenomenon, with the recommendation to place either a supraglottic airway or endotracheal tube when performing advanced airway management during in-hospital cardiac arrest based mainly in clinical trials conducted in the out-of-hospital setting. The Hospital Airway Resuscitation Trial (HART) is a pragmatic cluster-randomized superiority trial comparing a strategy of first choice supraglottic airway to a strategy of first choice endotracheal intubation during resuscitation from in-hospital cardiac arrest. The design includes a number of innovative elements such as a highly pragmatic design drawing from electronic health records and a novel primary outcome measure for cardiac arrest trials—alive-and-ventilator free days. Many of the topics explored in the design of HART have wide relevance to other trials in in-hospital cardiac arrest populations.

Factors influencing community-facility linkage forcase management ofpossible serious bacterial infections among young infants inKenya.

Despite evidence showing the feasibility and acceptability of implementing the World Health Organization's guidelines on managing possible serious bacterial infection (PSBI) in Kenya, the initial implementation revealed sub-optimal community-facility referrals and follow-up of PSBI cases. This study explores facilitators and barriers of community-facility linkages in implementing PSBI guidelines in Busia and Migori counties, Kenya. We used an exploratory qualitative study design drawing on endline evaluation data from the 'COVID-19: Mitigating Neonatal Mortality' project collected between June and July 2022. Data include case narratives with caregivers of sick young infants (0-59 days old) (18), focus group discussions with community health volunteers (CHVs) (6), and in-depth interviews with facility-based providers (18). Data were analysed using an inductive thematic analysis framework. Between August 2021 and July 2022, CHVs assessed 10 187 newborns, with 1176 (12%) identified with PSBI danger signs and referred to the nearest facility, of which 820 (70%) accepted referral. Analysis revealed several factors facilitating community-facility linkage for PSBI treatment, including CHVs' relationship with community members and facilities, availability of a CHV desk and tools, use of mobile app, training and supportive supervision. However, challenges such as health system-related factors (inadequate providers, stockout of essential commodities and supplies, and lack of transport/ambulance) and individual-related factors (caregivers' refusal to take referrals) hindered community-facility linkage. Addressing common barriers and fostering positive relationships between community health workers and facilities can enhance acceptance and access to PSBI services at the community level. Combining community health workers' efforts with a mobile digital strategy can improve the efficiency of the identification, referral and tracking of PSBI cases in the community and facilitate linkage with primary healthcare facilities.

Adequacy Analysis Using UAV of Heavy Rainfall Disaster Reduction Facilities According to Urban Development in Republic of Korea

Urban development is a project that enhances human life, but its hydrological impact increases runoff by expanding impervious areas. Furthermore, localized and intense rainfall resulting from the effects of climate change is exacerbating damage to urban areas. The Republic of Korea has established detention ponds as reduction facilities for heavy rainfall disasters, and the law stipulates that the impact of disasters that increase due to the development projects will remain unchanged from before. However, ensuring precision in millimeter or centimeter units during the design of reduction facilities is challenging. In this study, our aim is to assess the suitability of using unmanned aerial vehicles (UAVs) for the detention pond, a facility that reduces runoff resulting from urban development. The target area is a detention pond located in Innovation City, Ulsan Metropolitan City, Republic of Korea. We compared and analyzed design drawings and topographical data. The increased runoff due to the development project was 0.59 m3/s, and the effectiveness of disaster reduction was evaluated by the installation of a detention pond. The detention pond’s reduction effect was analyzed to be 1.16 m3/s for the design drawing and 1.57 m3/s for the topographical analysis. The detention pond currently in place in the target area was found to provide additional disaster reduction benefits compared to the original design plan. The findings of this study can be utilized in relevant laws and guidelines as a method to evaluate the suitability of future reduction facilities.

Research on the Application of Flipped Classroom in University Furniture Design Course- Taking Leshan Normal University as an Example

Between the Lines: An Exploration of Online Academic Help-Seeking and Outsourced Support in Higher Education: Who Seeks Help and Why?

The growth in online higher education has seen the ‘unbundling’ of some services as universities have partnered with private companies in an effort to enhance their services. This paper explores university students’ use and perceptions of the third-party online learning support platform, Studiosity, at Dublin City University. Studiosity was engaged to support undergraduate and postgraduate distance students, by offering support beyond existing campus-based services. This research employs a primarily inductive research design drawing on data collected through the third-party provider (2018–2020), supplemented by an in-house online survey (2019). Students were overwhelmingly positive about Studiosity. Postgraduate students, arguably students with good academic skills, used the service more than first-year undergraduate students. However, first-year undergraduates, a group the literature suggests are reluctant users of institutional support, were also strong users. Questions emanating from postgraduate students demonstrated expedient help-seeking. First-year undergraduate students were more concerned with explanations to help their understanding in order to persist with their studies. This paper posits that all other things being equal, those who already have strong academic capital will be the greatest users of academic support services. Proactive, less formal academic support strategies to encourage use by those who need help most, remain critical.

Automation of trimming die design inspection by zigzag process between AI and CAD domains

Quality control using artificial intelligence (AI) has led to considerable improvements in the manufacturing industry. However, inspection of computer-aided design (CAD) drawing to prevent potential errors is still performed manually by engineers. The design inspection which involves sequential and repetitive processes is labor-intensive, time-consuming, and prone to human error. In this study, we developed an automatic design inspection system for CAD data by integrating AI module and CAD software. The target product of this study is automobile trimming die design. The AI modules replace the engineers’ judgment, and the CAD software performs the operations requested by the AI modules. The design inspection is completed through a zigzag interaction between the AI modules and CAD software by a one-click operation without the intervention of experts. In the zigzag interaction process, 3D CAD files are converted to 2D images for interaction from the CAD software to the AI modules, and the output of the AI modules is transferred to the CAD software through VBA macros. The AI modules are designed to be CAD-independent and data-efficient; therefore, they can be easily adapted to other CAD software and achieve a high performance, even when trained with a few trimming dies. The length measurement error is only 2.4 % on average, which is at the 14th place out of 18 grades according to ISO 286–1:1988 standard tolerance. Additionally, the inspection time is reduced to approximately one-fifth of the manual inspection time by experts.

QOL-24. FINANCIAL AID REQUESTS BY BRAIN TUMOR PATIENTS IN ONTARIO THROUGH GOFUNDME

Abstract Brain tumors affect individuals globally including Ontario residents. Numerous Ontario brain tumor patients suffer the unequal burden of responsibility to pay for treatments like oral chemotherapy. In addition to chemotherapy, patients and their families have other costs associated with their diagnosis. However, less is known about other direct and indirect financial costs due to their diagnosis. GoFundMe, an online fundraising platform, provides worldwide brain tumor patients the opportunity to raise money for financial assistance with costs associated with their diagnosis The purpose of this study was to analyze publicly-available data from GoFundMe, an online fundraising platform, to explore the financial needs of brain tumor patients across Ontario, unaware and/or unable to get assistance elsewhere. A qualitative descriptive design drawing on thematic analysis was used to analyze GoFundMe requests to support individuals diagnosed with brain cancer in Ontario between 2014 and 2021. A coding framework was created to determine emerging themes using qualitative data analysis software NVivo 10. A final sample of 154 requests described financial strain from the loss of income experienced by the patient and their caregivers to afford cancer treatments. Requests highlighted 1) an overall lack of awareness of how and where access financial aid and affordable psychosocial support; 2) concerns over the long-term financial well-being of bereaving family members; 3) A call for more public awareness of the financial burden and emotional distress experienced by of those impacted by brain cancer. These GoFundMe requests highlight a connection between financial burden and emotional distress and an overall lack of awareness of where/how to seek financial and emotional support. These results will serve as the foundation to advocate for and raise awareness of the financial assistance needed by brain tumor patients and their families.

DISP-05. UNDERSTANDING THE INDIVIDUAL CHALLENGES AND EXPERIENCES OF YOUNG ADULTS WITH A DIAGNOSIS OF GLIOBLASTOMA AND HIGH-GRADE ASTROCYTOMA

Abstract High-grade gliomas are highly aggressive and fatal primary malignant brain tumors in adults with ineffective existing treatment methods. Older adults are greatly impacted by high-grade gliomas as they are more common among this population. Young adults (individuals aged 18-39) are uniquely impacted by high-grade glioma. However, there are few resources and information available to address these unique needs. The purpose of this study is to explore the lived experience of this population to inform the development of resources to help address their specific needs. A qualitative descriptive design drawing on thematic analysis was chosen to conduct and analyze interviews with young adult high-grade glioma patients at the Princess Margaret Cancer Center. Interviews focused on patient experiences as a high-grade glioma patient at Princess Margaret Cancer Center, the challenges they face and changes they would like implemented. A coding framework was created to determine emerging themes using qualitative data analysis software NVivo 10. To date, 5 interviews (1 men; 4 women; age range 19-37) have been completed. Interviews described the challenges living with high-grade glioma as a young adult and the changes in resources and support services patients would like implemented. Experiences highlighted 1) difficulty accepting this change in life and disruptions brought upon life goals and plans at the young adult age; 2) an overall lack of young adult high-grade glioma specific education, advocacy and support resources 3) A call for more community building and connecting so patients do not feel alone through this diagnosis. These patient interviews highlight a connection between the young adult age and high-grade glioma diagnosis and the challenges experienced and the services required. These results will serve as the foundation to advocate for the creation of tools that cater to patient needs of young adult high-grade glioma patients.

Aplikasi Visualisasi Pembangunan Jalan Baru Menggunakan Augmented Reality

Augmented Reality Technology that combines the real world with the virtual world, is interactive in real time, and is in the form of 3D animation. The Markerless Augmented Reality method is also called the markerless method, with this method the user no longer needs to use a marker to display digital elements. Currently, the construction of a road still uses a lot of rough drawings or designs using paper prints. The problem faced by workers is that drawings for making new roads use design drawings in 2D which are printed on paper, paper is prone to damage if it is always taken to the work site, such as being exposed to water, dust and folding which could damage the image on the printed paper. The research that will be carried out uses Augmented Reality technology which can provide information in the form of 3D road pavement images as well as information about the layers that make up the road pavement.

Application of unmanned aerial vehicles (UAV) in building 2D maps and 3D current status models for planning design

The article presents the topographic survey work using unmanned aerial vehicle (UAV) images to build 2D maps and 3D current status models. This technology has been used in many areas of life, but in Vietnam in planning design, it has not been widely applied.. Planning architects still follow the traditional method of relying on the 2D basemap database plus input data collected from various sources and at the request of the Investor to analyze and design the plan.. The products created from the above inputs are 2D detailed design drawings and 3D design models. It will be difficult to avoid shortcomings and limitations that will affect quality and slow progress due to design adjustments.. The design and application of the results from UAV equipment such as 2D topographic maps, image maps, 3D current status models, digital elevation models (DEM), point cloud data, etc. will improve the quality of design and planning management, in addition to adding an approach to green, sustainable design, responding to climate change and natural disasters.
