    The paper aims to develop a MAMDANI fuzzy controller for detecting the financial sustainability risk of the assets owned by the company. This type of risk indicates when an asset no longer produces economic benefits to the company, or the benefits are small enough to no longer justify the asset maintaining in working order. The proposed fuzzy controller has as input variables the asset operating expenses and the variation of this category of expenses from one analysis period to another. The controller's objective function is to keep operating costs at their initial state and thus reducing the financial sustainability risk. The controller's output variable is represented by the economic benefits variation, considered to be an essential component in the financial sustainability risk analysis. The obtained results were interpreted taking into account the objective function of the controller as well as the evolution of the input variables. Two simulations for fuzzy controllers were made, with the mention that the variation ranges for the input variables were delimited. In practice, fuzzy controllers can be generated according to company policies to keep under control the expense categories that accompany the asset exploitation

    Background: Total hip arthroplasty (THA) is a procedure that removes damaged bone and car-tilage and replaces it with prosthetic components and is performed by orthopedics. Objective: management of post-operative rehabilitation of THA patients in terms of content and comple-tion criteria of physiotherapy sessions. The research aims to explore the experience of Romani-an physiotherapists about the content and completion criteria of physiotherapy sessions in-volved in the management of postoperative rehabilitation after THA. Methods: The method used in this study was a questionnaire-based survey, with 120 Romanian specialists in the field completing an online screening tool that contained, along with a socio-demographic question-naire, a series of questions about their professional experience. Results: One of the most im-portant results of the study is the identification of statistically significant associations between the completion criteria of physiotherapy sessions and three techniques included in the rehabil-itation program after THA: edema management, gait re-education exercises, and exercises to increase hip mobility. Conclusion: The the research revealed that the experience of Romanian specialists regarding postoperative rehabilitation after THA is concordant with the experience of specialists in the field, and can be used to develop and test an individualized therapeutic protocol and to design continuing professional training programs for physiotherapists in Romania

    The muscle strength of the hip joint can be used as a criterion of quality rehabilitation patients after total hip arthroplasty

    Background: The primary aim of this study is to evaluate the efficacy of rehabilitation following total hip arthroplasty (THA) through the assessment of hip joint mobility parameters, namely abduction, extension, and flexion, at 2, 4, and 6 weeks post-surgery. These evaluations coincide with the implementation of rehabilitation exercises recommended by the physiotherapist. The study intends to analyze the progression of hip mobility during these specific time intervals in conjunction with the prescribed rehabilitation program. By examining the relationship between the performed exercises and the observed improvements in hip mobility, the research aims to provide valuable insights into the effectiveness of the rehabilitation protocol in facilitating post-THA rehabilitation. Material and method: The evaluation of hip joint mobility encompassed measurements of abduction, extension, and flexion utilizing a "Active Force 2" digital dynamometer. In tandem, the functional assessment of patients' health status was conducted through the utilization of the WOMAC index (Western Ontario and McMaster Universities Osteoarthritis Index). Results: The experimental data acquired in the measurement joint mobility during abduction, extension and flexion at 2, 4 and 6 weeks of exercises performed after THA are presented. Pain: mean score decreased from 3.08 to 1.18 (38.31% improvement); physical difficulties: mean score decreased from 3.10 to 1.01 (32.25% improvement) and joint stiffness: mean score decreased from 3.41 to 0.65 (19.06% improvement). These findings highlight the effectiveness of the recovery exercises in reducing pain, improving physical function, and decreasing joint stiffness post-THA. Conclusions: Our research emphasizes the essential contri-bution of physiotherapists to achieving positive outcomes for patients post-THA surgery. Through a personalized physiotherapy regimen administered during follow-up appointments, patients undergoing THA exhibited notable functional improvements. The study's results high-light the efficacy of this approach in alleviating discomfort, expediting recovery, and enhancing patients' overall quality of life, enabling a smoother transition back to normal daily activities

    Scoliotic postural alignment in prepubertal children: somatoscopic analysis of anatomical landmarks and development of a working model to limit spinal changes

    Background. The study aims to perform a somatoscopic analysis on a sample of 100 prepubertal children aged 10-14 years, girls and boys, who are diagnosed with scoliosis. Somatoscopic as-sessment is one of the most commonly used, therefore we thought that making a way of inter-preting the results could be useful to monitor postural attitude in children diagnosed with sco-liosis. Identifying the early onset of physical impairment in the spine with somatoscopy can be a key factor in maintaining optimal postural status. This approach may help in achieving a way of working that limits the negative effects of scoliosis on the subjects. Materials and methods. The selection of subjects is based on exclusion and inclusion criteria related to age, comorbidi-ties, therapeutic approach, and other criteria. Also, aspects that accompany the growth and de-velopment process of children in this prepubertal period and factors that may disturb this pro-cess are described in detail. Also in this context, we will present basic notions of body posture and etiopathogenesis of the onset of scoliotic deficiencies in children during this period of growth and development. Somatoscopic analysis is performed in the orthostatic position and is based on the identification of anatomical landmarks of the body concerning body posture. Re-sults. From the total analyzed scoliosis, n = 100, 74% are type „C” scoliosis and only 26% are type „S” and in terms of gender, 59% are girls and 41% boys; type „C1” (Cobb angle <100) scoliosis n = 60, with an angulation < 100 are 43.24% stabilized, therefore type „C1” scoliosis are more likely to be stabilized. „S”-type scoliosis with an angulation < 150 is only 3 cases repre-senting 11.53%, and those with an angulation from < 200 to < 400 are number 23 cases 88.64% which concludes that „S” type scoliosis is more aggressive and more difficult to manage. Con-clusions. Our study show that only 13% of the subjects had a regression of the angulation fol-lowing the kinetotherapy program, therefore the main objective remains to stabilize the scoli-osis attitude and limit the effects of this pathology. A regular assessment and somatotopic analysis resulting in a physiotherapy exercises program containing corrective postural postures and postural education is the most beneficial approach to stabilize the postural deficit
