Authors: Corona-Rios Fred , Langar Sandeep
Published: May 2024

In recent years, the US population of lower socioeconomic status has had an increased experience of uncertainty in being able to acquire affordable housing, and this issue is only being augmented by the limited innovation in the US residential construction industry. Although there is limited innovation being introduced in the US residential construction sector of the US, 3D printing (3DP) or additive manufacturing, a broader term utilized by industry professionals, has been at the forefront of discussion among Architects, Engineers, Constructors, Owners, and Operators (AECOO) in recent years. Utilizing a literature review, this study identified the 52 obstacles/barriers the construction industry faces in implementing 3D printing in the residential sector. Of the 52 identified barriers impeding 3DP adoption, the top three obstacles were Cost, Training Cost, and Complexity. The research also identified that most identified barriers could be associated with the Relative Advantage of the innovation. One of the practical implications of the study’s findings is that there needs to be collaborative efforts between housing industry stakeholders, policymakers, and technology manufacturers to facilitate incentives and training programs to alleviate some of the obstacles/barriers identified in the research.

Authors: Wu Hongyue , Chen Yunfeng , Zhang Jiansong , Jenkins James L.
Published: May 2024

Work zones are unique construction sites having multiple elements and complex scenarios. Existing studies have utilized crash data to explore the key factors contributing to work zone crashes. However, studies covering various elements comprehensively are missing, especially in Indiana. Also, there is a lack of studies exploring how to identify the representative scenarios from a large number of work zone crashes. Thus, this study aims to investigate the key factors contributing to work zone crashes covering multiple elements and propose a procedure to select representative scenarios based on crash data. Three Indiana crash data resources and the Natural Language Processing method were applied. There are several key findings. The key factors from multiple resources were summarized, including road conditions, work zone elements, and environment. Traffic activities were the top factors, followed by construction vehicles and weather conditions. Then, a seven-step procedure to extract the representative scenarios from crash records was proposed. Applying the procedure, two representative cases were identified from Indiana crash data. The study enhances the comprehensive understanding of work zone crashes based on large- scale data and helps improve safety for workers, drivers, and pedestrians.

A Framework for Model-Based Estimating in Preconstruction: A Scalable Approach
Authors: Pilgrim Brent , Valdes-Vasquez Rodolfo
Published: May 2024

The preconstruction field has struggled to adopt model-based practices and often lags behind in implementing similar BIM-based workflows in the construction industry. Model-based estimating practices provide a mechanism to increase efficiency and improve the overall preconstruction process. However, even as rapid growth in technology continues, current barriers to adoption persist, and the industry is challenged to educate and train the workforce to use these technologies effectively. A simplified model-based estimating framework must be identified and standardized to solve these barriers to adoption. This paper proposes a framework supporting a software-agnostic, standardized BIM-based workflow for preconstruction called the Integrated Estimating workflow, which relies upon five categories: 1) Intentional Model Authoring, 2) Qualitative and Quantitative Data, 3) Integration of Cost, 4) An Estimating Standard, and 5) Application of Automation or Augmentation to either parts of or the whole process. The significance of this framework is to identify an uncomplicated, but standardized model-based estimating workflow, and to create an identifiable distinction between this workflow and others commonly referred to as model-based estimating workflows.

Authors: Wetzel Eric M. , Young Michael , Umer Muhammad
Published: May 2024

Construction materials account for a significant percentage of the resources on a construction site and plays a vital role in the success of the project. By utilizing an experimental methodology, the goal of this research was to execute a proof of concept for autonomous inventory management of construction materials using Ultra-High Frequency passive RFID and a terrestrial autonomous robot. An experiment was administered to identify the reliability (tags read vs. tags placed) of the proposed system in a dynamic environment in autonomous mode. According to the results, the robot was largely able to navigate around and between smaller objects versus larger obstacles. Using Bootstrap simulation, the successful read rate (percent) was found to be [67,88] [LL, UL] at a 95 percent confidence interval. Based on the results, using a Boston Dynamics SPOT with UHF Passive RFID to control building material inventories could be a viable route with additional research. Future research will improve material management through RFID, computer vision, and Bayes Filters for localization.
Feedback Chats: Providing Individualized Feedback in a Construction Management Classroom
Authors: Barnes Andrew
Published: May 2024

Construction management (CM) students need more feedback from their teachers—feedback that is timely, individualized, informational, and edifying. Unsurprisingly, this is very difficult for CM teachers to provide given their constraints in both time and resources. This paper describes one way to offer CM students more feedback using a novel pedagogical method called “Feedback Chats” that applies elements of the flipped classroom and the fishbowl teaching strategy to free up class time for students and teachers to connect individually and regularly. Feedback Chats were first implemented in an undergraduate CM course called Housing and Land Development located at a major university in the southeast United States. Based on thematically analyzed data from end-of-course surveys administered by The University, students felt that Feedback Chats were effective, and they appreciated the direct and routine student-teacher contact that the teaching method provided. Key takeaways from this exploratory study are that feedback needs to be (1) timely, even before an assignment is submitted, if possible, (2) spoken, not written, and (3) committed to by the teacher ahead of time. (4) CM Teachers should recognize that even with Feedback Chats, class time will always be scarce.

Comparing the eCO2 Emissions Effects of Two Slab-on-Grade Screeding Methods
Authors: Cape Carter , Valdes-Vasquez Rodolfo , Dunbar Brian
Published: May 2024

While previous research has been conducted on concrete production to improve sustainability while retaining durability and constructability, this research focuses on construction practices in slab-on- grade screeding and how project management decisions can impact eCO2 emissions. A comparative life-cycle assessment of manual and laser screed was performed in a traditional 100,000 SF slab with 6" thickness. The study aimed to determine the effects of a slab-on-grade's equivalent embodied carbon (eCO2) in commercial projects. Two embodied carbon calculators (EC3 and Green Badger) were used to examine the differences between the two methods. Industry professionals provided actual commercial project data to determine the impact of laser screed compared to manual screeding. This study found that laser screeding reduced schedule, workforce requirement, and concrete waste for the slab-on-grade installation. These results demonstrate an important reduction in embodied carbon due to reduced worker transportation and concrete manufacturing emissions. The findings also indicate that project managers can improve the environmental sustainability of their projects by using alternative techniques, such as laser screed equipment, compared to manual screeding.

Authors: Okunola Akinwale , Akanmu Abiola , Jebelli Houtan
Published: May 2024

Active back-support exoskeleton has gained recognition as a potential solution to mitigate work- related musculoskeletal disorders. However, their utilization in the construction industry can introduce unintended consequences, such as increased fall hazards. This study examines the implications of using active back-support exoskeleton on fall risk during construction framing tasks, incorporating wearable pressure insoles for data collection. Two experimental conditions were established, one involving the simulation of construction framing tasks with exoskeleton and the other without exoskeleton. These tasks encompassed six subtasks: measuring, assembly, nailing, lifting, moving, and installation. Foot plantar pressure distribution was recorded across various spatial foot regions, including the arch, toe, metatarsal, and heel. Statistical analysis, employing a paired t-test on peak plantar pressure data, revealed that the use of active back-support exoskeleton significantly increased fall risks in at least one of the foot regions for all subtasks, except for the assembly subtask. These findings provide valuable insights for construction stakeholders when making decisions regarding the adoption of active back-support exoskeleton in the industry. Moreover, they inform exoskeleton manufacturers of the need to develop adaptive and customized exoskeleton solutions tailored to the unique demands of construction sites.

Published: May 2024

Sustainability in the built environment is often judged by the presence and type of third-party sustainability assessment programs. Third-party rating systems offer independent and verifiable point- based metric systems to assess a building's adherence to a set of sustainable building principles. This study assesses mass timber structures' relationship to third-party rating systems in order to determine how sustainable mass timber structures are. A regression analysis of 370 completed commercial mass timber structures across the U.S. provides strong evidence that mass timber structures correlate with the presence of third-party rating systems, especially LEED. The data shows the presence of third- party certifications in over 36% of projects, a vast majority (64%) being LEED certified. Results highlight the overwhelming percentage of mass timber structures deciding to pursue sustainability certifications. Importantly, researchers gain additional building attribute knowledge relative to this new structural technology.

Güneydoğu Anadolu’daki Ra’sü’l-Ayn Çiftliğinde Tarım ve Hayvancılık Faaliyetleri (19. Yüzyıl)
Authors: Şanda Mehmet Nuri
Published: May 2024

Osmanlı Devleti’nde tarım ve hayvancılık toplumsal hayatı ve ekonomik yapıyı şekillendiren ana unsurlardan biridir. Devlet, farklı konum ve rütbelerdeki memurlara gerçekleştirdikleri hizmetler karşılığında maaş niteliğinde topraklar tahsis etmiştir. Bu durum, devleti hem maaş ödeme gibi büyük bir mali yükümlülükten kurtarmış hem de boş toprakların üretime açılmasını sağlamıştır. Üretime açılan bu topraklar üzerinde birçok tarım ve hayvancılık faaliyeti gerçekleştirilmiştir. Bu araştırmada Ra’sü’l-Ayn Çiftliği’ndeki tarım, meyvecilik ve hayvancılık faaliyetleri üzerinde durulacaktır. Ayrıca çiftlikte tarım alanındaki modernleşme çalışmaları, tohum miktarları, çiftlikte yer alan Maşuk arazisine ait demirbaş listesi, Ra’sü’l-Ayn Çiftliği’nde ipek böceği yetiştiriciliği ve Sur kasabasındaki susuzluk sorununun çiftlik arazisinden geçen akarsu aracılığıyla çözülmesi gibi konular hakkında bilgiler verilecektir. Araştırmada, Osmanlı arşiv belgelerinde yer alan bilgi ve veriler transkripsiyon edildikten sonra içeriğine göre sınıflandırılmış ve yorumlanarak araştırmaya dâhil edilmiştir. Yapılan literatür taramasında Ra’sü’l-Ayn tarihi hakkında bazı tez ve kitap çalışmalarına rastlanmışsa da 19. yüzyılda Ra’sü’l-Ayn Çiftliği’nde tarım, meyvecilik ve hayvancılık faaliyetlerine dair herhangi bir araştırmaya rastlanmamıştır. Bu sebepten dolayı araştırmanın literatürde bir boşluğu dolduracağı düşülmektedir.

Introduction. Prostate cancer (PC) is one of the most frequently diagnosed malignant diseases among men. It is necessary to search for new methods of additional visualization. The most promising modern diagnostic method is histoscanning (HS) with the software «True Targeting», which allows you to perform «targeted» prostate biopsy (PB) in real time. We conducted a comparative observational clinical study with anonymous Internet survey implemented based on the SurveyMonkey program. Material and methods. The survey of urology specialists was initiated from the beginning of the «Moscow program for «Histoffusion» biopsies». The survey was composed of 16 questions. Data were obtained and analyzed on the doctor's work experience, experience in performing pancreatic biopsy, hospital, features of the operation, method of choosing anesthesia, patient position and complications in the postoperative period. Results. The division by hospitals showed that transrectal prostate biopsy is performed under the conditions in one day hospital in 80% of cases. Biopsy takes no more than 19 minutes on average. Half of the respondents had experience about 5 years, and only about 15% about 15 years. About 68% of specialists recommend performing MRI with contrast. However, only 22% of patients perform results. About 16% note the impossibility of performing MRI due to contraindications or other difficulties of the healthcare system. The most common complications are hemospermia and hematuria. In 100% of cases, respondents noted the need to prescribe antibiotic therapy. In 64.9% of cases, doctors note the need for a histoscan-guided prostate biopsy, and 82.1% are sure that in the future it is necessary to standardize the method of performing histoscan-guided prostate biopsy. Conclusion. We note the lack of standardization of histoscan-guided prostate biopsy. We suggest that the results of histoscan-guided prostate biopsy can be improved by developing a standardized follow-up as well as an algorithm aimed at optimizing for each patient.

Introduction. Antibacterial drugs are the basis of pharmacotherapy of lower urinary tract infections (UTI), and there is a growing interest in alternative nonantibacterial methods of their treatment and prevention. Purpose of the study. Quantitative evaluation of the anti-adhesive and antibacterial effects of the dietary supplement «Uronext®» containing D-mannose, vitamin D3 and cranberry extract against uropathogens isolated from patients with recurrent UTI. Materials and Methods. 124 strains of uropathogens isolated from the urine of women with recurrent UTI were studied. At the first stage of the study we determined the sensitivity of microorganisms to Uronext dietary supplement. In its presence, uropathogens were the material for the second stage of the study, during which the minimum inhibitory concentration of «Uronext®», its effect on the adhesion index (AI) of uropathogens, as well as the degree and duration of antimicrobial activity were evaluated. Results. The direct antibacterial effect of «Uronext®» against 53.7% of Gram-negative and 51.7% – of Gram-positive microorganisms strains was revealed. A pronounced anti-adhesive effect of the investigated product was noted, especially against Gram-negative bacteria. The anti-adhesive effect of «Uronext®» was the greatest in the first 4 hours and lasted for the whole 24-hour observation period. The minimum inhibitory concentration of «Uronext®» for Gram-negative bacteria was 8 times lower than for Gram-positive bacteria. Antibacterial activity of «Uronext®» was manifested already 1 hour after the product was added to the cell culture, reached the highest value in 2 hours and remained at the maximum level during 5 hours of observation. The mentioned tendency was characteristic for all investigated microorganisms. Conclusion.

Introduction. Penile skin flap and oral mucosal graft are most often used for augmentation urethroplasty for extended anterior urethral strictures. It seems relevant to conduct a study comparing augmentation urethroplasty techniques using these donor materials. Materials and methods. The review is based on articles published throughout history in scientific peer-reviewed journals included in the databases PubMed (https://www.ncbi.nlm.nih.gov/pubmed/), Embase (https://www.embase.com/landing), Cochrane Library (https://www.cochranelibrary.com/), Scientific Electronic Library eLibrary.ru (https://elibrary.ru/). The search was performed on the following keywords: «urethral stricture», «anterior urethra», «penile urethra», «bulbous urethra», «urethroplasty», «augmentation urethroplasty», «penile skin flap», «oral mucosa graft». At the first stage, 445 sources were found, of which 17 articles were included in the review. Results. A total of 17 original studies were identified with a comparative analysis between one-stage augmentation urethroplasty techniques using a penile skin flap and an oral mucosal graft for penile and/or bulbous urethral strictures. 7 (41,2%) studies were a randomized controlled trial, 10 (58,8%) studies were a retrospective cohort study. The total number of patients in whom a flap or graft was used across all studies was 1426. A penile skin flap was used in 638 (44,7%) patients, and an oral mucosal graft was used in 788 (55,3%) patients. The success of treatment using a penile skin flap averaged 77,8%, and an oral mucosal graft averaged 83,7%. Conclusions. Penile skin flap and oral mucosal graft, when used for augmentation urethroplasty, can achieve a similar treatment success rate. When assessing the outcome of urethroplasty in cohorts of patients with long-term postoperative follow-up and a relatively large sample size, the best results were characteristic of oral mucosal grafts.

Introduction. Bladder obstruction caused by benign prostatic hyperplasia (BPH) is common disease among males with diabetes mellitus (T2DM). Objective. To evaluate lower urinary tract symptoms (LUTS) and clinical outcomes among patients with/without DM2T after undergoing transurethral resection prostate (TURP). Materials and methods. Retrospective study based on medical data throughout 1,5 years (2021–2022 гг.) and participation of 48 diabetic and non-diabetic patients with persistent LUTS who also have underwent TURP for BPH. Results. Patients with DM2T show higher prevalence of cardiovascular diseases (р=0,01). They also show higher need for alpha-blockers during 1-12 months after TURP for urinary dysorders (OR=5,5, 95% CI: 1,42–21,30, р=0,01). Discussion. Wide-population prospective clinical studies are needed for creating of effective personalized strategies. Conclusion. Patients with T2DM more often need alpha-blockers within 1-12 months after TURP. T2DM leads to higher rate of post-surgery urinary retention and worse results compared with non-diabetic patients.

Digital technology is the fastest growing area with major implications for healthcare. In neurology, this can provide better accessibility in consultations, expanding the potential of various diagnostic and therapeutic tools and systems. For example, telemedicine allows expanding access to services, overcoming geographical barriers, thereby providing the opportunity to provide medical care not only to patients, but also to their relatives. The widespread introduction of artificial intelligence elements into the routine practice of a neurologist helps make decisions on diagnosis, treatment, assessment of development and prognosis of various neurological diseases. This article describes digital health technologies for providing care for neurodegenerative diseases, demyelinating diseases, dementia, stroke and epilepsy.

Introduction. Attention deficit hyperactivity disorder (ADHD) is a disease of the group of neuropsychiatric developmental dis- orders, the main symptoms of which are hyperactivity, attention deficit and impulsivity. Behavioral disorders in ADHD, the childhood age of most patients, the need to control the side effects of psychotropic drugs, and limitations in the availability of medical care сan lead to the need for searching for alternative options for the management of patients with this disorder, such as telemedicine and methods of remote monitoring of the disease. The aim of this review is to analyze modern methods of professional medical care for patients with ADHD. Materials and Methods. Literature review was conducted using PubMed, Scopus, and GoogleScholar databases, and the study included literature sources not older than 5 years. Results. We conducted a literature review and analyzed current trends in the management of patients with ADHD using remote technologies. Currently, all these steps can be achieved by using of telemedicine technologies: remote teleconsultations, the use of digitized questionnaires and cognitive tasks, the introduction of psychotherapeutic tools into patients' daily lives through augmented and virtual reality technologies, and the use of apps and wearable devices for symptom tracking. Conclusion. In summary, the analysis has demonstrated the certain aspects of managing patients with attention deficit hy- peractivity disorder using telemedicine technologies. Modern technologies make it possible to achieve control over the course of ADHD, reduce the severity of its symptoms and improve the quality of life of patients with ADHD.
