Justification of the safe parameters of recreational zones during the reclamation of watered residual quarry spaces

Purpose. To determine the safe parameters of the recreational zones created in the residual space of the quarry taking into account the physical and mechanical properties of waste rocks in a watered state. Methodology. The Bishop Simplified Method is used to determine the influence of the irrigation level of the residual quarry space on the stability of the embankment from different types of mining rocks when creating a recreational area during reclamation works. Findings. The safe parameters of recreational areas during their construction in the watered residual space of the quarry were established taking into account the physical and mechanical properties of embankments made of sand, loam, and crushed rock by determining the stability of their slopes. The obtained results are necessary for the implementation of project works on the development of technological schemes for the reclamation of the residual spaces of construction materials quarry for the recreational direction of post-mining. Originality. The influence of the height of the rock embankment formation on the stable angle of inclination of the watered slope was established, which allowed determining that with an increase in the aggregates embankment height from 20 to 80 m, the safe angle of the slope will decrease from 46 to 26°. It was determined that the lowest FOS indicator is 0.57 when using sand rocks for an embankment height of 80 m at a water content of 40 %. It was established that with partial flooding of the rock embankment by 45–50 % for sandy, loamy and rocky rocks, there is a significant decrease in the coefficient of the reserve of stability by 1.4–1.5 times, in contrast to the absence of water or complete flooding, which confirms the negative impact of partial flooding of embankments and reducing the stability of their slopes. Practical value. It was determined that when forming an embankment 20 m high from loamy rocks, the volume of reclamation works will be 1.34 times less compared to sandy rocks, but 1.02 times larger than rocky rocks. When the height of the embankment increases to 80 m, the volume of reclamation works when replacing loam with sand will increase to 1.87 and 1.12 times when using crushed stone. However, taking into account the market value of materials, when using loam, the cost of construction will decrease by 2.5 times compared to sandy rocks and 3.2 times – to crushed stone, with an embankment height of 20 m. When the embankment height increases to 80 m, the cost of materials will increase by 3.5 and 3.8 times when loamy rocks are replaced by sand or crushed stone, respectively.

Stakeholders’ Perspectives on Rehabilitation Services in KwaZulu-Natal Province, South Africa: A Mixed-method Study

Background and Objectives: South Africa is committed to enhancing rehabilitation services by 2030 through the National Rehabilitation Policy and the United Nations Convention on the rights of persons with disabilities. However, limited research focuses on rehabilitation services in KwaZulu-Natal (KZN) Province, South Africa. This study aims to provide insights from stakeholders on rehabilitation services in KZN Province focused on infrastructure, referrals, human resources, and multidisciplinary practices. Methods: Using mixed methods, we conducted focus group discussions, interviews, and surveys involving 99 stakeholders, including rehabilitation practitioners, district and provincial managers, and social development representatives from eThekwini, AmaJuba, and King Cetshwayo in South Africa. Descriptive statistics and thematic analysis were used for quantitative and qualitative data. Results: Public institutions reported inadequate referral pathways (2.9 out of 5) compared to private institutions (3.4 out of 5). Acute rehabilitation referrals primarily targeted secondary or tertiary facilities. Disjointed pathways, a lack of protocols, delayed referrals due to various factors and insufficient staff were identified. Physiotherapists were disproportionally more prominent, while social workers, psychologists and bio-kineticists were scarce. Both public (93%) and private (73%) care exhibited high doctor-to-patient ratios. Rehabilitation service disciplines were limited and fragmented, especially in rural areas. Thirty-four respondents (81%) stated no designated rehabilitation services units in their respective institutions. Conclusion: Rehabilitation services, though present at all care levels in KZN, mostly begin at tertiary levels. Local-level rehabilitation is non-existent, with the public healthcare system relying on community rehabilitation workers. Referral pathways require standardization, especially at the local level. Enhancing primary healthcare’s rehabilitation focus by bolstering workforce recruitment can significantly improve multidisciplinary practices. Expanding intermediate care facility licenses can alleviate system strain on KZN’s public health sector.

«Владельцы песков»: пескоукрепительные работы на землях кочевых народов Юга России (ногайцев, калмыков и туркмен) в XIX – начале XX веков

The publication examines the organization of sand protection works carried out in semi–desert zones of Southern Russia in the XIX - early XX centuries. Despite separate publications on measures to combat desertification in the Russian Empire, sand protection activities that unfolded in the XIX – early XX centuries on the lands of the nomadic peoples of Southern Russia (Nogais, Kalmyks and Turkmens) did not become the subject of separate works, which determines the nov-elty of the study. The peculiarities of the natural, climatic and geographical living conditions of nomads and their irrational use of arid zones as pasture lands for their livestock were factors that caused the rapid growth of sands in the XIX – early XX centuries. Sand protection works in the south and officials of the sand-ravine parties and the corps of foresters of the Forest Department, under the jurisdiction of the Ministry of State Property, carried south-east of Russia out. The ac-tivities of sand protection organizations included experimental measures to combat desertifica-tion, which included husking and grass sowing on the sands, sowing sandy oats, removing sands from the use of their owners, forestry and horticulture in the steppe. The source base of the study was materials extracted from the State Archives of the Stavropol Territory (GASK) funds: 153 «Forester of the Stavropol sandy-ravine district» and 247 «Stavropol Provincial Forest Protection Committee». Historiographical works on the study of the problem include publications by pre–revolutionary, Soviet and modern researchers involved in combating desertification in Southern Russia in the XIX - early XX centuries. The analysis of materials and sources made it possible to trace the peculiarities of the activities of central and regional authorities, local societies (A.D. – owners of sands), and other organizations that participated in sand protection works during the historical period under consideration. The conclusion is formulated that the sand protection activi-ty that unfolded in the South of Russia in the XIX – early XX centuries. It included many forest reclamation works, the purpose of which was to curb the process of desertification of pasture and agricultural lands of Nogais, Kalmyks and Turkmens, which in turn was a measure of protection and guardianship of the life, health and economic and cultural activities of nomadic peoples with-in the Russian Empire.

Building Resilience through Territorial Planning: Water Management Infrastructure and Settlement Design in the Coastal Wetlands of Northern Apulia (Salpia vetus-Salapia) from the Hellenistic Period to Late Antiquity

This Gulf of Manfredonia has, for millennia, been the primary water feature of the coastal wetland of Northern Apulia, Italy, although modern reclamation works make writing its long-term history challenging. Our recent paleoenvironmental research has reconstructed the evolution of the southern half of this lagoon since the Neolithic period. Here, we write a history of water management and environmental change in this landscape from the perspective of two key urban sites: pre-Roman Salpia vetus and Roman Salapia. The Roman architectural historian Vitruvius recounts the abandonment of Salpia vetus and the refoundation of Salapia. We employ his narrative as a frame for a more complex environmental history, starting from a historiography of this landscape’s study and a summary of our interdisciplinary research agenda, which unifies environmental, topographical, remote sensing, and archaeological approaches. Resilience in this changeable wetland environment was only possible through an integrated and intentional management of water among rivers, the lagoon, and the Adriatic Sea. While Salpia vetus exploited this wetland and thrived for centuries, the settlement eventually collapsed due to human and environmentally impelled factors. Roman Salapia subsequently emerged with a different approach, new infrastructure, and a new location. This blueprint would sustain urban life in this wetland for six centuries and lay the groundwork for the Medieval town.

Mapping annual dynamics of surface mining disturbances in the northeastern Tibetan Plateau using Landsat imagery and LandTrendr algorithm.

The exploitation and utilization of coal resources have significantly contributed to global energy security. However, this mining activity has inflicted considerable damage on the ecological environment, particularly on the Tibetan Plateau, where the impact on ecosystems may be even more detrimental. The implementation of high-intensity mining activities leads to rapid changes in land cover/land use. Consequently, it is essential to accurately and effectively monitor mining disturbances. In this study, we propose an approach to capture surface mining disturbances using spatial-temporal rules and time series stacks of Landsat data. First, a time series of annual mining disturbance probability was generated based on Landsat temporal-spectral metrics and random forest. Second, the Landsat-based detection of Trends in Disturbance and Recovery (LandTrendr) algorithm was employed to segment the time series and detect breakpoints. Finally, mining disturbances were captured by further restricting the output of LandTrendr based on spatial-temporal rules of mining disturbances. This approach was applied and evaluated in the Muli mining area of the northeastern Tibetan Plateau, which experienced large-scale and rapid mining disturbances from 2004 to 2014, and identified a disturbed mining area of 43.62 km2. The mining sites have been reclaimed after mining, and all reclamation work was done after 2016, with a total reclaimed area of 22.28 km2. The validation results indicated that the overall accuracy of mining disturbance and reclamation mapping ranges from 0.7333 to 0.8667, and the F1 scores for mining disturbances and reclamation range from 0.7551 to 0.8723. This study provides a reliable framework for monitoring mining disturbances and reclamation in surface mines, promising to be useful in realizing disturbance monitoring in surface mines for a wide range of mineral types.

Does sexual rehabilitation work for gay and bisexual prostate cancer patients? Acceptability, feasibility, and efficacy results from the Restore-2 randomized controlled trial.

Sexual minority prostate cancer patients have worse health-related quality of life outcomes than heterosexual patients. We conducted the first study to test whether sexual and urinary rehabilitation tailored for sexual minority patients was acceptable, feasible, and efficacious at improving their sexual and urinary function. Restore-2 was a 24-month randomized controlled trial of an online biopsychobehavioral rehabilitation study for sexual minority men treated for prostate cancer experiencing sexual and/or urinary problems. Participants were 401 US sexual minority men treated for prostate cancer and experiencing sexual and/or urinary problems at baseline. Intervention components included phosphodiesterase-5 inhibitors, sexual aids, a pelvic floor exercise regimen and video, a guide to good gay sex following treatment, and coaching. Quality of life assessments were completed at baseline, 3, 6, 12, 18, and 24months. We confirmed good acceptability and feasibility, but only minimal improvement was observed over time and no differences were found between treatment and control arms. We found no evidence that the intervention improved sexual or urinary outcomes for participants. However, we confirmed excellent acceptability and feasibility for a sexual rehabilitation program tailored to sexual minority participants. In addition, participants reported enduring usage and acceptability of sexual aids (including vacuum pump, anal dilators, and penile constriction rings) as well as masturbation and pelvic floor exercises to accommodate their sexual challenges. Sexual "accommodation," rather than "rehabilitation," may be a more accurate and realistic goal for this population. Patients should be provided sexual aids to help accommodate their sexual and urinary challenges. This study was retrospectively registered with ClinicalTrials.gov, study number: NCT03923582; date: 22/04/2019.

Rehabilitating Workers Aged 55 and Over: Professionals' Perspectives and Solutions.

Work disability affects a growing number of workers aged 55 and over (W55 +). While rehabilitation programs have demonstrated efficacy for workers with an average age of 42, they often have not been designed to meet unique needs of aging workers. This study aimed to describe the difficulties encountered by work rehabilitation professionals and explore their solutions for improving services offered to W55 + . This study used a simple descriptive design with purposive sampling. Occupational therapists, physical therapists, and psychologists were mainly recruited in private clinics. An interview guide based on the Work Disability Paradigm was piloted and used with the participants. Qualitative interviews were conducted with work rehabilitation professionals and then transcribed. A thematic analysis was performed. The sample consisted of fifteen participants (average age 38years) with near equal representation across genders and disciplines. Difficulties were identified in relation to the (1) characteristics of W55 + , (2) work environment, (3) compensation system, and (4) communication among stakeholders. Five solutions were proposed to improve the services offered: provide healthcare professionals with access to tools and training, implement communication mechanisms, integrate a return-to-work coordinator, develop a joint action plan for managing W55 + , and implement an integrative prevention approach in workplaces. Our results represent a first step in mapping various stakeholders' needs to ensure better support for W55 + with work disabilities. These results delineate a roadmap for future research that should expand upon these stakeholders' perspectives to provide a more comprehensive description of their needs and potential solutions.

Court-ordered forensic psychiatry treatment in prison: determinants of outcome and risk mitigation.

Court-ordered forensic psychiatry treatments (COT) are specifically designed to reduce the risk of violence in mentally disordered offenders. Given their high costs and ethical issues, mental health professionals need admission criteria to be able to select those candidates with optimal benefit. This study analyses offender-related and treatment-related determinants of COT outcome and risk mitigation. This two-year longitudinal study assessed the evolution of 117 adult offenders admitted to a specialized medium-security forensic psychiatry clinic. Treatment outcome included court-ordered discharge locations and the Historical Clinical Risk Management (HCR) score evolution. Treatment progress was assessed every six months across five time-points including measures of protective factors, work rehabilitation and security. Outcome determinants included psychiatric diagnosis and type of offence. Discharge locations are predicted by pre-treatment risk level. Lower HCR scores are associated with discharge into low-security psychiatry wards independently of the psychiatric diagnosis. Risk reduction follows diagnosis-specific and offense-related patterns and reveals that mentally disordered offenders with Cluster B personality disorders or those sentenced for drug crimes are significantly less prone to benefit from COT. Our findings indicate that criminological characteristics at baseline as well as diagnosis of personality disorders are the main determinants of treatment outcome in our care setting. Inmates with concomitant higher violence risk at baseline and presence of Cluster B personality disorders might benefit the least from court-ordered forensic inpatient psychiatric care in prison.

Moisture Sensitivity Performance of Hot Mix Asphalt Mixture Incorporating Fly Ash Geopolymer (FAG) Asphalt Binder

In Malaysia, Hot Mix Asphalt (HMA) is widely used in asphalt production. HMA is a mixture of asphalt and aggregates that give durability to the road surface for pavement. Due to vehicles excessive traffic loadings that cause road surface damage, this pavement technology frequently undergoes maintenance and rehabilitation work. This study used recycled material as a modified binder and showned the best result in increasing stiffness and better rutting performance with high percentages of additives. This research focuses on the effect of FAG additive on asphalt mixture performance evaluation according to SuperpaveTM mixes design method. The procedures were specified according to the American Association of State Highway and Transportation Officials (AASHTO), American Society for Testing and Materials (ASTM), British Standard (BS) and Malaysian Standard (MS). The granite aggregate type was produced by a local quarry with conventional asphalt binder grade 80/100 and 60/70. Incorporation FAG in modified asphalt binder as levels of 0, 3, 5, 7, 9, and 11% by mass of asphalt binder. The performance of moisture sensitivity showed low moisture damage susceptibility for the mixture based on consistent values of TSR, in which all the specimens met the minimum TSR threshold of 80%. The optimization findings indicated that 9% of fly ash geopolymer might be the ideal content for modifying the asphalt binder. Overall, research findings suggest that using geopolymers may have improved some of the characteristics of asphalt binder and the performance of asphalt binders in pavement applications. Thus, the outcomes of this research were significantly used for further performance test and analysis on the asphalt mixture.

Improving Work Rehabilitation Program at PT. KALPRI

The work rehabilitation program is one of the important efforts made by the company to help employees who are experiencing health conditions that disrupt work productivity to return to work optimally at PT. KALPRI, there has been an increase in the number of employees undergoing work rehabilitation programs accompanied by a low success rate in returning employees to their original positions after undergoing the program. Therefore, this study aims to identify the factors that cause this condition to occur. This research uses a descriptive quantitative approach, using a questionnaire instrument for 71 respondents and conducting in-depth interviews with 5 members of the rehabilitation committee at PT. KALPRI. The collected data is then analyzed to identify the key factors influencing the increase in rehabilitated employees and the program’s low success rate. The research results show that the internal factors causing the rise in the number of employees being rehabilitated are the employees’ unhealthy habits and lifestyles, such as smoking habits, irregular exercise, and rest, which trigger the emergence of various diseases such as cardiovascular, musculoskeletal, and obesity. Externally, the COVID-19 pandemic has also contributed to the increase in the number of employees being rehabilitated due to restrictions on activities that have impacted employee health. Meanwhile, the internal factors that cause the low success rate of the rehabilitation program are the employees’ habits and lifestyles that slow down the healing process, so some employees have to undergo a “long sick” program that extends the rehabilitation period. Externally, the activity restrictions due to the COVID-19 pandemic have also contributed greatly to the low reabsorption of employees after undergoing a rehabilitation program. The findings of this study indicate the need to increase more intensive health interventions and education to change employees’ habits and lifestyles, as well as the need for stronger coordination between the rehabilitation team and management in managing work rehabilitation programs, especially during the pandemic. These efforts are expected to help improve PT. KALPRI’s work rehabilitation program’s success.

Visible body and invisible mind: Bureaucratic performance, self-rehabilitation, and the machinery of Chinese community corrections

Based on a recent ethnographic study of community corrections in two large Chinese cities, this study examines how the rehabilitation work, as the cornerstone of Chinese community corrections, is deployed as a people-processing apparatus that counts offenders’ bodies but almost excludes their agency. In practice, offenders are instrumentalized and disciplined to make up the Chinese community corrections machinery, whose subjectivity is either completely muted or selectively mediated. Given justice actors’ adherence to bureaucratic hierarchy and preoccupation with administrative requirements, offenders are mostly marked as counts and treated more as penal objects utilized to fulfill intricate metrics-related requirements. Justice agents’ formalistic pursuit of, rather than substantive investment in, the well-being of offenders renders their participation in Chinese community corrections symbolic and strenuous. It further breeds offenders’ commitment to self-rehabilitation, a process of relying on self-discipline and personally discovered resources for compliance and reintegration. We contend that the current operation of the Chinese community corrections apparatus, under the rehabilitative guise, exacerbates offenders’ structural disadvantages and reinforces their stigmatized identities. Policy and research implications of this study are discussed.

The moderating effect of altruism on the relationship between occupational stress and turnover intentions: a cross-sectional study of community rehabilitation workers in China

BackgroundIn China, community rehabilitation workers are facing a growing challenge related to heavy occupational stress, which is having an impact on employment turnover. Previous studies have explored the effect of the public service motivation of workers in “helping” jobs on occupational stress or turnover intention, but there is a lack of clarification of the impact of altruism on turnover intention in the case of complex pathways involving various factors.MethodsA stratified sampling method was used, and a total of 82 community rehabilitation workers who assist disabled people from 34 community health centres in Jiangmen city were included in the study from August to October 2022. The turnover intention, occupational stress, burnout, quality of life, altruism, and certain sociodemographic information of community rehabilitation workers were measured using a structured questionnaire. The partial least squares method was employed to construct and test the structural equation model.ResultsAlthough altruism had no direct impact on occupational stress or turnover intention, altruism moderated the effect of occupational stress on burnout (βMod = −0.208) and quality of life (βMod = 0.230) and weakened the mediation of burnout and quality of life between occupational stress and turnover intention.ConclusionsThis study proposes to address the dilemma of “strong function” and “weak specialty” in community rehabilitation services and to conduct positive psychological interventions for community rehabilitation workers through the guidance of altruistic values.

Assessment of Modern Restoration of Biogeocenoses in Reclaimed Areas with Coal Enrichment Waste

It has been found that areas of differentiated and undifferentiated technosoils with plant species diversity (from 21 to 26) are characterized by intense processes of vegetation restoration occurring in them. A gradual increase in the proportion of native species relative to ruderal species, as well as a gradual increase in species diversity, was noted. It was concluded that the ongoing processes of restoration of vegetation cover at the studied sites indicate the effectiveness of the reclamation work carried out using coal benefication waste.

Speech-language performance and comorbid disorders in children with perisylvian syndrome induced by viral encephalitis.

Viral encephalitis is one of the main causes of the perisylvian syndrome, which can cause damage to children's language-speech, feeding, and swallowing functions. Comprehensive assessment of language-speech and swallowing function and comorbidity research on these children will help children's rehabilitation workers to better understand the disease and strengthen the systematic management of comorbid disorders. To describe speech and language pathology and the occurrence of comorbid disorders in children with perisylvian syndrome induced by viral encephalitis. Twenty-two children with acquired perisylvian syndrome were recruited in this study. Language and speech functions, including oral motor function, swallowing function, language ability, and dysarthria were assessed in these patients. Craniocerebral magnetic resonance imaging (MRI), electroencephalogram examination, and intelligence evaluation were performed to determine brain lesions and comorbid disorders. All children exhibited different degrees of oral movement, dysphagia, and speech and language disorders. There was a significant difference between expressive and receptive language ability (P<0.05). There were 10, 8, and 12 children who had an intellectual disability, limb disability, and epilepsy, respectively. In addition to the damage of the peri-tegmental cortex found in MRI, thalamus lesions occurred in 19 cases and white matter involvement in six cases. Children with acquired perisylvian syndrome caused by viral encephalitis are characterized by persistent pseudobulbar dysfunction, speech and language impairment, and orofacial diplegia. They have a high probability of secondary epilepsy and are prone to motor and cognitive impairment, which need systematic management.

Technological innovations in cardiac rehabilitation: effectiveness and impact on patient's quality of life

Introduction: Today, the issue of effective rehabilitation of patients after ischemic damage to the heart muscle is relevant in connection with the annual increase in the number of patients with chronic cardiovascular pathology. The aim of our study was to establish modern effective methods of cardiorehabilitation through a literature search. Methods: A review of the literature on the topic of innovations in cardiorehabilitation using databases: GoogleScholar, PubMed, Web of Science, Scopus was carried out using the survey and system analysis method. These methods provide the possibility of remote monitoring of patients with chronic cardiovascular diseases using telemonitoring, which encourages patients to monitor the state of the cardiovascular system based on ECG, blood pressure, and oximetry. Telecardiorehabilitation is a modern method that has been widely implemented in the last 10 years, and especially during the outbreak of the COVID-19 pandemic. Taking into account that after discharge from the hospital , elderly people sometimes find it difficult to get to rehabilitation centers or work in groups. Development: As an alternative, specialists found the possibility of physical rehabilitation with a set of exercises at home and constant monitoring with the help of smart technologies. The introduction of modern techniques increased the percentage of patients who were involved in cardiorehabilitation, which reduced mortality rates and positively affected the quality of life of patients. Conclusions: The implementation of telemonitoring and telecardiorehabilitation in the conditions of aging population and increasing share of patients with chronic course is a very promising direction of modern rehabilitation

Documentation as part of substance use rehabilitation: how workers account for the significance of documentation during interviews

PurposeThe focus of this article is in documentation in substance abuse inpatient rehabilitation. Our article scrutinizes how workers give accounts of the documentation in the inpatient substance abuse rehabilitation unit and what kind of client information the workers record.Design/methodology/approachThe study focuses on institutional interaction and practices. Our data consist of interviews with substance abuse rehabilitation professionals (N = 15). We analyzed the interviews using content analysis and the account concept in keeping with the ethnomethodological research tradition.FindingsStudy shows how workers account for the significance of documentation. Workers deemed documentation significant in four different ways: in gathering basic and rehabilitation information, in storing and transmitting information, as a tool for analysis and assessment and in supporting linguistic transparency in substance abuse rehabilitation. Workers justified the significance of documentation by the legal requirement to record information about clients. Documented information enables clear management of client information and supports substance abuse rehabilitation work in various ways. Documentation contains descriptions of the client’s situation and work performed. Additionally, documentation serves as a tool for communication among social care professional.Originality/valueThus the research show that documentation plays a significance part in the inpatient substance abuse rehabilitation and are connected to its institutional tasks and practices.

Return to work rate of individuals after cardiac rehabilitation and the demographic and impairment factors that influence return to work in the Western Cape, South Africa

Background Cardiovascular disease (CVD) commonly affects individuals within the working age group, often resulting in unemployment, particularly in low- to middle-income countries. The purpose of the study was to determine the return to work (RTW) rate of individuals with CVD after cardiac rehabilitation (CR) and the impact of impairment and socio-demographics on the individual’s ability to (RTW). Methods A cross-sectional survey, namely the Work Rehabilitation Questionnaire (WORQ) was used to gather the information. The IBM SPSS software (version 25) was used to manage the statistical analysis. Individuals who completed a CR program between the ages of 18 and 64 years made up a sample of 63 research participants. Results The RTW rate reported that only 30 (47.6%) of the participants successfully RTW after CR and 33 (52.4%) of participants did not RTW. The results also indicated that the older the individual and the higher the degree of impairment experienced, the less likely RTW would occur. Conclusion Factors such as the age and level of functional impairment of the individual with CVD must be addressed more aggressively in CR programs, particularly if the goal of the individual with CVD is to RTW.

NDT Data-Supported Structural Reassessments based on Regression Relations in Measuring Data Analysis

Non-destructive Testing (NDT) yields valuable data on actual structural elements, supporting the assessment of existing infrastructures while minimizing additional structural damage caused by inspections. Simultaneously, the uncertainty in measurement, which quantifies the quality of measurement results, plays a crucial role in decisions aimed at, e.g., optimizing maintenance strategies, rehabilitation works and Structural Health Monitoring (SHM) implementations. The Guide to the Expression of Uncertainty in Measurement (GUM) framework has been already applied to non-destructive concrete testing. This necessitates an obligatory process in which extensive measurements with strictly limited scopes need to be conducted by expert personnel. This study aims to simplify and optimize existing NDT data analysis procedures by employing regression analysis, enabling the detection of structural features. The regression analysis yields a modifier for determining the correct depth of an object within the structural element as well as an intercept in the linear input-output formulation, with time of flight serving as the variable and wave velocity as its slope. The method is validated through laboratory experiments, including the use of an ultrasonic measurement system. The introduced method provides unbiased and accurately measured results, while the measurement data can be uncorrelated. Major advantages are faster computations, a wider scope and a notable reduction in the amount of needed information about the measuring process. Furthermore, the study illustrates how the regression relation approach, in combination with ultrasonic data describing the inner structure of a concrete element, can effectively support the reassessment of bridges in operation. To achieve this, the measurable positions of the resisting longitudinal tendons of a bridge structure are varied to investigate the displacement change under dynamic service loads. The findings reveal that the application of the proposed NDT analysis method, with its increased practicability, can enhance the efficiency of NDT data-supported structural reassessments in different scenarios.
