Co-Designing the MOSAIC mHealth App With Breast Cancer Survivors: User-Centered Design Approach
Authors: Nuseibeh Betsey Zenk , Johns Shelley A , Shih Patrick C , Lewis Gregory F , Gowan Tayler M , Jordan Evan J
Published: October 2024

Background

Breast cancer is the world’s most prevalent cancer. Although the 5-year survival rate for breast cancer in the United States is 91%, the stress and uncertainty of survivorship can often lead to symptoms of depression and anxiety. With nearly half of breast cancer survivors living with stress and symptoms of depression and anxiety, there are a significant number of unmet supportive care needs. New and potentially scalable approaches to meeting these supportive care needs are warranted.

Objective

This study aimed to engage breast cancer survivors and acceptance and commitment therapy (ACT) content experts in user-centered design (UCD) to develop a mobile health app (MOSAIC [Mobile Acceptance and Commitment Therapy Stress Intervention]) using stress intervention strategies.

Methods

We held 5 UCD sessions with 5 breast cancer survivors, 3 ACT content experts, 2 user experience design experts, and 1 stress expert facilitator over the course of 10 weeks. The sessions were developed to lead the 10 co-designers through the 5-step UCD process (eg, problem identification, solution generation, convergence, prototyping, and debriefing and evaluation). Following the fifth session, a prototype was generated and evaluated by the 5 breast cancer survivors and 3 ACT experts using the System Usability Scale, Acceptability E-scale, and a brief set of semistructured interview questions.

Results

The 10 co-designers were present for each of the 5 co-design sessions. Co-designers identified 5 design characteristics: simple entry with use reminders (behavioral nudges), a manageable number of intervention choices, highly visual content, skill-building exercises, and social support. A total of 4 features were also identified as critical to the use of the tool: an ACT and breast cancer–specific onboarding process, clean navigation tools, clear organization of the interventions, and once-per-week behavioral nudges. These requirements created the foundation for the app prototype. The 5 breast cancer survivors and 3 ACT co-designers evaluated the app prototype for 1 week, using an Android smartphone. They rated the app as usable (mean 79.29, SD 19.83) on the System Usability Scale (a priori mean cutoff score=68) and acceptable (mean 24.28, SD 2.77) on the Acceptability E-scale (a priori mean cutoff score=24).

Conclusions

Through the UCD process, we created an ACT app prototype with 5 breast cancer survivors, 3 ACT experts, and 2 UCD designers. The next step in our research is to continue the assessment and refining of the prototype with additional breast cancer survivors. Future work will pilot-test the app to examine the feasibility of a large-scale, randomized control trial. Studies will enroll increasingly diverse breast cancer survivors to broaden the generalizability of findings.

Published: October 2024

Background

Collecting the medical history during a first outpatient consultation plays an important role in making a diagnosis. However, it is a time-consuming process, and time is scarce in today’s health care environment. The computer-assisted history taking (CAHT) systems allow patients to share their medical history electronically before their visit. Although multiple advantages of CAHT have been demonstrated, adoption in everyday medical practice remains low, which has been attributed to various barriers.

Objective

This study aimed to implement a CAHT questionnaire for orthopedic patients in preparation for their first outpatient consultation and analyze its completion rate and added value.

Methods

A multicenter implementation study was conducted in which all patients who were referred to the orthopedic department were invited to self-complete the CAHT questionnaire. The primary outcome of the study is the completion rate of the questionnaire. Secondary outcomes included patient and physician satisfaction. These were assessed via surveys and semistructured interviews.

Implementation (Results)

In total, 5321 patients were invited, and 4932 (92.7%) fully completed the CAHT questionnaire between April 2022 and July 2022. On average, participants (n=224) rated the easiness of completing the questionnaire at 8.0 (SD 1.9; 0‐10 scale) and the satisfaction of the consult at 8.0 (SD 1.7; 0‐10 scale). Satisfaction with the outpatient consultation was higher in cases where the given answers were used by the orthopedic surgeon during this consultation (median 8.3, IQR 8.0‐9.1 vs median 8.0, IQR 7.0‐8.5; P<.001). Physicians (n=15) scored the average added value as 7.8 (SD 1.7; 0‐10 scale) and unanimously recognized increased efficiency, better patient engagement, and better medical record completeness. Implementing the patient’s answers into the electronic health record was deemed necessary.

Conclusions

In this study, we have shown that previously recognized barriers to implementing and adapting CAHT can now be effectively overcome. We demonstrated that almost all patients completed the CAHT questionnaire. This results in reported improvements in both the efficiency and personalization of outpatient consultations. Given the pressing need for personalized health care delivery in today’s time-constrained medical environment, we recommend implementing CAHT systems in routine medical practice.

Scoring the invisible

Published: October 2024

This article discusses the computational and material interplays embedded in the making of [re]capture, a research–creation project combining a bio-inspired installation that materialises particulate matter, together with outdoor sensing instruments that collect atmospheric data in at-risk neighbourhoods (Montreal, Canada). With impacts on health and the environment, habitual and slow forms of exposure to atmospheric pollution (Hsu 2016) outline the relationality of air and the porosity of bodies, both human and more-than-human (Nieuwenhuis 2016; Albano 2022). What kind of technical objects, and material-esthetics can “negotiate a rapprochement” (Gissen 2009, 22) with the invisible materiality of air? At the intersection of critical and bio-design, mechanical engineering, and computer science, [re]capture delves into this question through the lens of ‘filtration,’ simultaneously envisioned as a physical process for attending to atmospheric pollution, and as a generative concept for interpolating technology, materiality, and the city. While the artwork iterates a virtual testing model (Blender and ossia score) with physical prototyping, the article examines how to compose with air through digital simulation and scoring to create new alliances between porous meshes, bioindicators, data, particulate matter, light, wind, and electronics. It also asks How to design installations that embody and materialise the affective properties of air? Attending the speculative trajectory of this process, the article draws on feedback from computer-aided simulation techniques and collaborative experiments in residency spaces to investigate the ‘scoring’ of [im]materiality and explore the spatio-temporality of air.
El robot de Teléfonos Ericsson como representación de tecnología, superioridad y lujo en el México de 1932
Authors: López-León Ricardo
Published: October 2024

En el siglo XX nace el robot, símbolo de la tecnología, la innovación y el futuro. La Revolución Industrial nos heredó la obsesión por la automatización de procesos, pero también el miedo a la pérdida de empleos sustituidos por robots, y el miedo a que la tecnología y las máquinas controlen el destino de los humanos. Desde esta perspectiva, el objetivo de este artículo es mostrar cómo la compañía telefónica Ericsson, a principios del siglo XX, buscaba posicionarse en el público mexicano presentando la figura de un robot. Los hallazgos se muestran en dos anuncios de prensa publicados en 1932 en los que el robot enfatiza lo automático, promoviendo la sustitución del servicio manual, pero también resalta lo seguro que era el servicio para disipar los miedos a las máquinas. Además, persigue posicionar la tecnología como un artículo de lujo, declarando así que, a través del servicio de Teléfonos Ericsson, se podía conseguir distinción social en la sociedad mexicana postrevolucionaria.

Published: October 2024

The stability and reactivity of the five (5) 2-[(benzimidazolyl)methylthio]-4,5-diphenylimidazole derivatives were studied using density functional theory at the B3LYP/6-31+ G (d, p) level. Analysis of the molecular electrostatic potential (MEP) map and determination of the dual descriptor showed that nitrogen N13, sulfur S5 and carbons C19 and C21 are nucleophilic. They are therefore susceptible to electrophilic attack. The nitrogens N2, N3 and N14 are shared between electrophilic and nucleophilic sites. The study of the chemical reactivity of our compounds was carried out based on the analysis of molecular frontier orbitals (HOMO and LUMO), energy gap (ΔƐ), chemical hardness (η), electrophilicity (ω) and chemical softness (S). Compound 1 was found to be the most stable, the least reactive and electron-donating. This study also opens up a new way of synthesizing biologically active molecules by modulating the C19 carbon with inductive electroattractant groups.
Keywords: Benzimidazole, Imidazole, DFT, ESP, reactivity, stability.
Unani Regimenal Therapy for Knee Osteoarthritis (Waja ‘al Rukba): A Comprehensive Scientific Assessment
Authors: Furquan Almas , Begum Mehmooda , Ahmad Ehsaan , Meraj Meraj
Published: October 2024

Pain in the joints has been a common and serious health issue for a long time. In Unani medicine, both inflammatory and non-inflammatory joint problems are grouped under the term "Waja‘al-Mafāṣil," which means joint pain. Osteoarthritis, based on its symptoms, is very similar to a condition in Unani medicine called Waja‘al-Mafāṣil Balghamī. One of the most common types of osteoarthritis is Knee Osteoarthritis (KOA), which is known in Unani medicine as Waja‘al Rukba. This chronic and painful condition is usually treated with non-steroidal anti-inflammatory drugs (NSAIDs), but these drugs can have many side effects. In contrast, the Unani system of medicine uses a more comprehensive approach to manage osteoarthritis. Waja‘al Rukba is managed with Istefragh (evacuation) followed by Tadeel Mizaj (rejuvenation), Taqwiyat (strengthened) and Taskeen (pain is relieved). Istefragh is achieved using specific Unani herbal treatments, like Munzij-Mushil Therapy followed by Tadeel Mizaj using various techniques, including Ḥijāma (cupping), Dalk (massage), Ta‘līq al-‘Alaq (leech therapy), Ḥammām (Turkish Bath), Takmeed (fomentation), Naṭūl (irrigation), Qay‘ (vomiting), and Ḥuqna (enema). Taskeen and Taqwiyat are achieved using either medications or these modalities. This overview focuses on Waja‘al Rukba and its Regimenal management.

Authors: Faizrakhmanov Ilshat Zavdatovich
Published: October 2024

The article is devoted to the study of the issues of participation of service Tatars on the side of government troops during the E.I. Pugachev uprising of 1773–1775. The reasons for the loyal attitude towards the autocratic power or neutrality of the main part of the service Tatars towards Pugachev’s "rebellion" are determined. The role of the Kazan Admiralty in maintaining order in the villages of service Tatars under its control, in places where timber for ships was being prepared, and in defending Kazan from rebels in the summer of 1774 has been clarified. The merits of a small part of service Tatars who actively participated in the suppression of the uprising are shown. The events on the territory of the Kazan district are considered primarily.

Authors: Jamaludin Nurul Atasha , Zaki Hafizah Omar , Ramli Raudha Md. , Suffarruddin Suhaida Herni
Published: October 2024

The COVID-19 pandemic has prompted a shift in payment approaches, with a preference for e-wallets. Despite their potential, Malaysians lag in adopting e-wallets. It is necessary to gain a deeper understanding of the factors influencing e-wallet adoption, especially through Gen Z. Therefore, we conducted this study using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework to explore the factors influencing e-wallet adoption among Gen Z. Interviews with eight members of Gen Z reveal that advantages like time savings and the ability to manage and monitor transactions drive the adoption of the e-wallet payment method. Emergent themes, such as government incentives and the convenience of donating, further delineate the adoption of e-wallets. The adoption of e-wallets will eventually promote sustainable consumption by replacing cash transactions and reducing carbon emissions due to the reduced physical transit of financial resources. This study enhances the UTAUT and suggests prospective avenues for the growth of e-wallets in Malaysia. Practically, the findings are advantageous for financial service providers that are enhancing their e-wallets, as well as for government initiatives to transition to a cashless society and ultimately achieve sustainable development goals.

Published: October 2024

In the past few years, there has been a significant focus on investigating the impact of social media engagement. Although previous studies recognize the importance of social media engagement, there is still a lack of in-depth analysis regarding the specific influences of likes, comments, and shares on consumer behaviour, especially concerning how these engagements affect different platforms. This study aims to examine the relationship between social media engagement metrics (likes, comments, and shares) and consumer purchase intention on two prominent platforms, Facebook and Instagram. By adopting a cross-sectional design, this study employed purposive sampling to gather data from Malaysian university students who have engaged in purchasing activities on social media platforms such as Facebook and Instagram. The analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) based on 265 completed responses, comprising 131 from Facebook users and 134 from Instagram users. The results reveal a significant positive relationship between likes and shares with consumer purchase intention on both Facebook and Instagram. However, comments were not found to be associated with consumer purchase intention on either platform. Furthermore, the study conducted a comparative analysis between Facebook and Instagram and found no significant differences in the relationships between engagement metrics and purchase intention. These findings have practical implications for marketers, emphasizing the importance of fostering engagement through likes and shares to drive consumer purchasing behaviour on social media platforms.

Authors: Acosta Cristina , Ordoñez Mayra , Blanco-Álvarez Hilbert
Published: October 2024

Este estudio tiene como objetivo aportar una visión panorámica de las características de los diseños de actividades matemáticas construidas desde una perspectiva etnomatemática. Se usó una metodología cualitativa y el material empírico analizado fueron artículos de revistas científicas publicados entre el año 2000 y 2019. El análisis fue orientado por las siguientes preguntas: ¿en qué área de las matemáticas se inscriben las actividades?, ¿qué objetos matemáticos son estudiados?, ¿para qué grado o población está diseñada la actividad?, ¿qué contexto se utilizó para el diseño de la actividad?, ¿qué materiales se utilizaron? y ¿en qué país se diseñaron? Para los resultados se realizó un estudio por cada una de las categorías de análisis que son los interrogantes planteados dando así respuesta a estos. Se pudo concluir que hay un mayor porcentaje de actividades en el área de geometría en comparación con áreas como álgebra y aritmética. Por otra parte, las actividades están diseñadas para niños de 5 años hasta adultos. Además, las actividades contemplan elementos del contexto, formas extraescolares de resolución de problemas matemáticos y en varias de ellas participa la comunidad en su creación y gestión en el aula.

Authors: Flórez-Góngora Carlos Humberto , Ramírez-Gamboa Juan Camilo , Márquez-Peñaranda Jorge Fernando
Published: October 2024

En este trabajo se ha investigado el escenario probable de daños producidos por efectos sísmicos en edificaciones de un sector urbano de la ciudad de San José de Cúcuta. Para ello, se aplica un método basado en la asignación de un valor relacionado con la calificación de once variables que incluyen aspectos estructurales clave para calcular el índice de vulnerabilidad relacionado con dos escenarios de máxima aceleración en roca. Como resultado, los datos globales se muestran utilizando un sistema de información geográfica. Dicha representación gráfica muestra que un alto porcentaje de edificaciones de uno a tres pisos tienen índices de daño que pronostican daños medianos y severos. Por lo tanto, es altamente probable que los edificios hechos de mampostería no confinada y pórticos resistentes a momentos de hormigón armado que tengan menos de cuatro niveles deban ser sometidos a refuerzo estructural u otras acciones tendientes a reducir la vulnerabilidad estructural.

La educación es la base del desarrollo del país, uno de los elementos básicos para lograr cambios sociales y beneficiar a la población. Por otra parte, a partir del 25 de marzo de 2020, el gobierno colombiano toma la decisión de implementar un aislamiento preventivo obligatorio, frente a la emergencia sanitaria global provocada por COVID-19, como consecuencia de esto, las personas permanecían aisladas, dando paso a la educación a distancia. Estudio cuantitativo descriptivo, correlacional, sobre las modalidad y calidad educativa durante el periodo de aislamiento por COVID-19 en el año 2020 en Colombia, se utilizaron los datos recogidos en el capítulo G Educación de la Encuesta Nacional de Calidad de Vida - ECV 2021 del Departamento Administrativo Nacional de Estadística -DANE. En el año 2020 durante el aislamiento por COVID-19, el 49,7% considera que la calidad de la educación se empeoró y el 37,7% que se mantiene igual, solo el 9.1% considero que mejoró. A pesar que algunas instituciones cuentan con un entorno informático desarrollado y con equipos necesarios para la realización de clases virtuales, éstas no están a la par con la calidad educativa que genera la presencialidad, por lo cual, el cambio de modalidades educativas afectó significativamente el aprendizaje de los estudiantes. Principalmente, la modalidad virtual fue la que tuvo mayor percepción negativa en cuanto a la calidad educativa, según la población encuestada, lo que demuestra que la calidad de la educación durante la pandemia tuvo un descenso.

Authors: Sojitriya Kalpeshkumar M. , Kalyankar V. D. , Champaneria K. V. , Chudasama G. P.
Published: October 2024

Efforts are made in this article to investigate the thermal and mechanical phenomena by presenting a coupled thermal and structural analysis of SA516 Grade-70 steel. This material has wide applicability in the fabrication of pressure vessels, boilers, etc., due to its excellent weldability and formability. An actual ongoing problem from a reputed industry, related to distortion during the shielded metal arc welding process, is considered and experiments are carried out on the chosen steel. Results are evaluated employing a two- step methodology, involving simulation. The first step encompasses thermal analysis, providing insights into transient temperature distribution, while the subsequent mechanical analysis offers data on residual stresses and distortion. In the case of heat input, a volumetric heat source with double ellipsoidal heat distribution is used whereas a plasticity material model with rate-independent bilinear kinematic hardening is adopted for the structural analysis. Additionally, temperature-dependent material properties are factored into both scenarios. The data derived from numerical analysis align closely with experimental findings, presenting valuable insights for fabricating industries.
Artificial Neural Networks Based Prediction of Penetration in Activated Tungsten Inert Gas Welding
Authors: Acharya Samarendra , Gonda Debasish , Das Santanu
Published: October 2024

Using GTAW, or tungsten inert gas (TIG) welding, weld penetration is usually lesser than the other arc welding processes. ATIG (Activated-flux TIG) welding can be a good alternative to provide deep penetration, and hence, improved productivity. In this work, 304L SS plate of 8 mm thickness was used as base plate, and a flux with a mixture of SiO2, MnO2 and MoO3 was used as a ternary flux in the ratio of 1:1:2. A 2-factor 3-level response surface methodology of central composite design was considered for designing experimental runs. Back Propagation (BP) type Artificial Neural Networks (ANN) model was developed to assess penetration in ATIG welding by using heat input and pulse frequency as the two process parameters. The ANN chosen has 2-10-1 network structure. Results show that the predicted values through ANN are conforming quite well to the experimentally obtained penetration, and hence, the applicability of ANN.
The role of stereotactic radiotherapy in the treatment of the local recurrence of colorectal cancer: A case report
Authors: Radosavljevic Kristina , Ivanov Olivera , Bojovic Marko , Licina Jelena , Protic Mladjan , Prvulovic-Bunovic Natasa
Published: October 2024

Colorectal cancer is one of the most common malignant diseases worldwide. A multidisciplinary approach to treatment involves surgery and chemotherapy, while radiotherapy is used in the treatment of tumors localized in the pelvis. Stereotactic radiotherapy allows the delivery of high, ablative radical radiotherapy doses to target volumes, with a reduced risk to the surrounding organs, making it suitable for irradiating localized disease. A 59-year-old female S.M. presented to the doctor due to the appearance of a perianal fistula. Colonoscopy was performed, revealing a moderately differentiated adenocarcinoma. Magnetic resonance imaging (MRI) examination diagnosed a tumor lesion of the rectosigmoid junction with a perilesional abscess collection and several fistulous channels communicating with the perianal skin. The patient underwent surgery with adjuvant chemotherapy. A follow-up MRI examination 8 months after surgery revealed a soft tissue lesion in the perianal tissue characterized as a recurrence of the disease, and stereotactic body radiotherapy (SBRT) was applied. Six months after SBRT follow-up examinations indicated a complete clinical response to radiotherapy without the recurrence of the primary disease. Stereotactic radiotherapy can be applied as an effective and safe ablative technique, particularly when considering the significant morbidity and impairment of the quality of life in patients after surgical treatment.
Breast imaging Reporting and Data System (BI RADS): Why don’t we use it correctly in the region?
Authors: Prvulovic-Bunovic Natasa , Mastilovic Milica , Stankov Maja , Nikolin Borislava
Published: October 2024

Breast Imaging Reporting and Data System (BI RADS) is used for the standardization of radiological reports in breast imaging, created by the American college of radiology (ACR). Standardized reports allow breast lesion characterization, malignancy risk assessment, and facilitate communication between doctors. The system is made for everyday clinical practice with the aim of improving the quality of diagnostics and anticipate the comparisons of results with colleagues from other health institutions, while in Serbia to assist in communication with colleagues from the region. The BI RADS system is composed of lexicon recommendations for structured radiological reporting and further management. Most health institutions in Serbia and surrounding countries use it, but in everyday clinical practice the system is not correctly implemented in all institutions. During daily imaging procedures we see radiological reports coming from different institutions in the region. Some of them clearly show that the system is misunderstood and not implemented correctly. Our aim is to evaluate the use of the BI RADS system in everyday clinical practice in Serbia and the region, to explain why it is not used correctly, and to point out the most common mistakes with the desire to make the system work adequately.
Foreign direct investment, domestic investment, and the role of institutions in Central, Eastern, and South-Eastern Europe
Authors: Bucevska Vesna , Merdzan Gunter
Published: October 2024

The paper examines the relationship between foreign direct investment (FDI)
and domestic investment in Central, Eastern, and South-Eastern European
(CESEE) countries from 1995 to 2021. The primary hypothesis posits that FDI
exerts a positive influence on domestic investment, with variations observed
across diverse institutional contexts. The research utilises fixed effects
and a one-step difference generalised method of moments (GMM) to determine
whether FDI leads to an increase or decrease in domestic investment in CESEE
countries. The findings indicate that FDI has a favourable and statistically
significant influence on domestic investment. However, the coefficients for
FDI are less than one, indicating that while FDI stimulates overall
investment, it does not create a crowding-in effect where the rise in total
investment surpasses the FDI inflows. When the data is split on the basis of
institutional quality, it is evident that FDI continues to positively impact
domestic investment in high and low-institutional- quality settings. The
coefficients for FDI in both subgroups are less than one, implying that
institutional quality does not substantially change the correlation between
FDI and domestic investment. These results indicate the positive and
significant impact of FDI on domestic investment, without crowding-in
effects for the entire sample of CESEE economies and both subgroups that
differ in institutional quality.
The disability gap in employment in developing economies: Evidence from the Nigerian labour market
Authors: Efayena Oba , Ichoku Eme
Published: October 2024

A viable and functional labour market is a sin qua non for economic
development. This study thus examines the evidence of disability-related
employment discrimination in Nigeria. Utilising the Fairlie decomposition
technique in analysing households? data elicited from wave 4 of the General
Household Survey, the study found that the disability gap in employment was
plausibly existent in Nigeria. The study therefore suggested, among other
viable options, that policies aimed at promoting the elimination of physical
obstacles in workplaces while also ensuring equitable training opportunities
for individuals with disabilities should be rigorously pursued. There is a
need to enact more stringent anti- discriminatory policies in Nigeria, with
individuals having functional difficulties being the focal target.

Published: October 2024

In a declining market, companies must adapt their strategies during the
mature stage to maintain competitiveness. One of the effective approach to
sustaining demand is through targeted promotional efforts, which can extend
the products demand in the market. Additionally, implementing an appropriate
pricing strategy is essential to ensure products are sold before its start
deteriorate or the season ends. This paper explores the role of promotional
efforts in shaping pricing policies for non-instantaneous deteriorating
items in the declining demand scenario. In the model, we consider the demand
as a function of both price and time, incorporating assumptions of partial
backlogging for shortages, losts sales, fixed holding costs, and
deterioration rate. Using these assumptions, we develop an inventory model
that starts with a shortage and ends with zero inventory. The objective is
to maximize expected profit per unit time by optimizing both the selling
price and replenishment schedules. The innovation of this study lies in
integrating promotional efforts with pricing strategies, specifically
designed for deteriorating items in a declining market. We present a
numerical example to demonstrate the model?s effectiveness and conduct a
sensitivity analysis to examine its performance under varying conditions.
Finally, we provide managerial insights and outline potential directions for
future research.
Factors associated with arthrofibrosis-related revision following 14,325 total or unicompartmental knee arthro-plasties: an analysis from the Dutch Arthroplasty Registry
Authors: Van de Ven Myrthe P F , Bongers Joris , Spekenbrink-Spooren Anneke , Koëter Sander
Published: October 2024

Background and purpose: Arthrofibrosis is a fibrotic joint disorder that can impair the results of knee arthroplasty surgery by limiting the range of motion, functionality, and quality of life. We aimed to investigate whether patient and procedural characteristics are associated with arthrofibrosis-related revision following unicompartmental and total knee arthroplasty (UKA and TKA).Methods: A prospective observational study was conducted using data from the Dutch Arthroplasty Registry. We included 14,325 revisions performed in 2014–2022 following primary knee arthroplasty. Demographic and surgical characteristics including age, sex, BMI, smoking status, and prosthesis type (TKA versus UKA) were analyzed. Multiple logistic regression was performed to investigate associations between these factors and arthrofibrosis-related revisions, compared with other reasons.Results: Revisions were due to arthrofibrosis in 711 (5%) patients. There were significantly higher associations for younger age (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.96–0.97)), male sex (OR 1.2, CI 1.0–1.4), lower BMI (OR 0.97, CI 0.95–0.98), non-smoking status (OR 1.7, CI 1.2–2.3), and TKA (OR 7.7, CI 5.2–12), for arthrofibrosis-related revision compared with any other reason for revision.Conclusion: Younger patients, men, non-smokers, patients with a lower BMI, and those who had primary TKA were more often associated with revision due to arthrofibrosis than other reasons for revision.
Influence of robot-guide strategies on the geometry of directed energy deposition components
Authors: Partes Knut , Schmidt Malte
Published: October 2024

Directed energy deposition (DED) for additive manufacturing applications is commonly realized by the usage of industrial robots. The DED processing end effectors are usually mounted on industrial robot systems and can, therefore, be moved and oriented in up to many degrees of freedom. However, the design of the powder nozzle and the programming of the robot can limit the movement options. For this reason, translational movements, as with conventional 3D printers, are still common today. The end effector is usually guided horizontal over the component surface although welding in position (PA) is preferred in general. It may be necessary to tilt the end effector in order to gain advantages during processing due to the constrained position. This is particularly advantageous for overhang structures and is often realized with the help of a turn-tilt positioning table in combination with an industrial robot. However, this approach is, in some cases, not possible due to geometrical constrains. To extend applications in this direction, advanced methods for slicing the components and programming the robot movements are necessary. The main aspect of this work is the development, testing, and evaluation of a multidimensional DED manufacturing approach. This is tested on a thin-walled component with defined overhang areas and compared with conventional approaches. Different strategies are assessed in terms of the geometrical match of the target geometry. Influences of strategies on the results are evaluated. It can be shown that multidimensional path planning approaches lead to a better match of the target geometry.
People with Mental Health Conditions in The Face of Argentine Criminal Law The Rules of Non-Imputability and the Necessary Reform in Light of International Treaties and Law 26557
Authors: C Zalazar
Published: October 2024

The new paradigms in mental health established by international conventions and legislation on the matter in Argentina (law 26557) have not been effectively received in the criminal sphere. This is so since interdisciplinary treatment is not applied for the purposes of determining the non-imputability of people (art. 34 of the Penal Code of Argentina), following the old slogan of psychiatry, nor is the dignity of the person respected. Who suffers from a mental illness? This has determined that in practice provisional or security measures result in the person who suffers from a mental illness and faces the criminal law, spending more time under said law than would have corresponded to him for the crime against him Impute. Human rights and the principle of conventionality require us to modify the matter
Unveiling the Nexus: Elevating marketing strategies for enhancing satisfaction and loyalty in elderly health care services
Authors: Bhuyan Bishal
Published: October 2024

The study aimed to examine whether there is an association of marketing mix, and perception with customer’s satisfaction, and loyalty among elderly people. A total of 400 participants were included in the study. The study population comprised individuals aged 65 years and above from Assam, India including both males and females. Participants were primarily selected from residential homes, old age homes, and various common gathering places such as parks, shops, Namghar (a holy place), and community halls. The study indicated a significant correlation between the dimensions of the marketing mix, perception, satisfaction, and loyalty. Moreover, the findings from the linear regression analysis, revealed customer satisfaction towards the marketing of healthcare services can be attributed to product, price, place, process, and physical evidence (7 P’s) and customer perception (R2=.54; .53 respectively). Additionally, customer loyalty towards the marketing of healthcare services is influenced by product and price (7P’s), and customer perception (R2=.54; .2 respectively). This study contributes to understanding the overlooked aspect of marketing to the elderly population, providing valuable insights for healthcare companies to develop improved marketing strategies. Hence, irrespective of the organization's size, type, or location, whether it's a startup or an established entity, privately owned or government-operated, local or global, the role of business managers is vital in making informed decisions and establishing strategic priorities to allocate resources efficiently in order to meet evolving customer demands and achieve business success. As a result, commercial enterprises need to develop tools, concepts, and strategies to effectively navigate the dynamic and unpredictable marketing landscape.

Authors represent bibliographical review and a clinical case report of Shprintzen-Goldberg syndrome (SGS) in an infant. SGS is a rare genetic disease that has been poorly studied and is of a practical and scientific interest due to the difficulty of its diagnosis, a fairly complex description of the phenotype and clinical polymorphism of manifestations. The purpose for publishing of this particular case report was to familiarize pediatric practitioners with this rare hereditary syndrome since there are no consensual clinical guidelines for the management of patients with SGS as yet. Identification of hereditary diseases accompanied by disruption of the structure and function of the musculoskeletal, cardiovascular and nervous systems would allow determining a more accurate plan for managing of a pediatric patient as well as establishing a possible prognosis for the patient’s further development, which is the number one problem considered by both parents/caregivers and physicians.
