Authors: Fernandez Miguel A. , Henshaw Freddie , Carlos William J. , Kelly Andrew , Griffin Xavier L. , Costa Matt L. 
Published: January 2025

AimsThere is compelling evidence for the use of cemented hip hemiarthroplasty for displaced intracapsular hip fractures; however, the risks of cement are well reported and in rare cases may be associated with haemodynamic collapse. It is therefore important to improve our understanding of haemodynamic instability, intraoperative monitoring, and strategies to reduce the risk to patients.MethodsWe measured arterial blood pressure using the LiDCOrapid Continuous Non-invasive Arterial Pressure (CNAP) finger cuff during surgery in patients enrolled in the WHiTE 5 trial randomized to cemented or modern uncemented hip hemiarthroplasty at a single recruiting site. We observed the incidence, timing, and magnitude of haemodynamic instability at key stages of the surgical procedure.ResultsWe obtained measurements from 56 patients, of whom 46 had complete recordings and were used in the analysis. Modest falls in systolic blood pressure (20% to 30%) occurred in four patients (15%) who received a cemented hemiarthroplasty and one patient (5%) in the uncemented group. The fall in blood pressure occurred either within five minutes of cementing or at final hip reduction. We observed concurrent drops in cardiac output (CO) and stroke volume (SV).ConclusionWe observed the presence of two potential periods for haemodynamic instability during hip hemiarthroplasty surgery: the first was within five minutes of cementing the femoral canal and the second after final reduction of the prosthesis (observed in both cemented and uncemented hemiarthroplasty). The falls in blood pressure appeared to be driven by reduced CO and SV.Cite this article: Bone Joint J 2025;107-B(1):103–107.

Published: January 2025

AimsThe aims of this study were to develop an automatic system capable of calculating four radiological measurements used in the diagnosis and monitoring of cerebral palsy (CP)-related hip disease, and to demonstrate that these measurements are sufficiently accurate to be used in clinical practice.MethodsWe developed a machine-learning system to automatically measure Reimer’s migration percentage (RMP), acetabular index (ACI), head shaft angle (HSA), and neck shaft angle (NSA). The system automatically locates points around the femoral head and acetabulum on pelvic radiographs, and uses these to calculate measurements. The system was evaluated on 1,650 pelvic radiographs of children with CP (682 females and 968 males, mean age 8.3 years (SD 4.5)). Each radiograph was manually measured by five clinical experts. Agreement between the manual clinical measurements and the automatic system was assessed by mean absolute deviation (MAD) from the mean manual measurement, type 1 and type 2 intraclass correlation coefficients (ICCs), and a linear mixed-effects model (LMM) for assessing bias.ResultsThe MAD scores were 5.7% (SD 8.5%) for RMP, 4.3° (SD 5.4°) for ACI, 5.0° (SD 5.2°) for NSA, and 5.7° (SD 6.1°) for HSA. Overall ICCs quantifying the agreement between the mean manual measurement and the automatic results were 0.91 for RMP, 0.66 for ACI, 0.85 for NSA, and 0.73 for HSA. The LMM showed no statistically significant bias.ConclusionThe results showed excellent agreement between the manual and automatic measurements for RMP, good agreement for NSA, and moderate agreement for HSA and ACI. The performance of the system is sufficient for application in clinical practice to support the assessment of hip migration based on RMP. The system has the potential to save clinicians time and to improve patient care by enabling more comprehensive, consistent, and reliable monitoring of hip migration in children with CP.Cite this article: Bone Joint J 2025;107-B(1):124–132.

Authors: Akinmoye Oluwambe 
Published: January 2025

Abstract
The cluster of small- and medium-scale garment industries in Aba and Onitsha positioned Nigeria to meet her garment needs. Regrettably, the production process is encumbered with manufacturing waste, which hinders competitiveness with their international counterparts. This study identified manufacturing waste in the garment production process in the garment industries in Aba and Onitsha with the view of improving the production performance. A survey research design with the use of a closed-ended questionnaire was used for data collection. In total, 372 questionnaires were administered, and 324 were completed and returned, representing 87% response rate. Descriptive statistics such as mean weighted scores was used to analyze the data for this study with the Statistical Package for Social Sciences, version 16. The result of the investigation revealed that unnecessary motion, overprocessing, inventory, waiting, and defects constitute major lean manufacturing wastes in the garment production process. Therefore, concerted efforts must be intensified by the garment industry to eliminate the identified waste with a view of ensuring the garments are competitive with foreign garments.
Large-scale production of highly responsive, stretchable, and conductive wrapped yarns for wearable strain sensors
Authors: Wang Linyu , Mao Lei , Wei Wei , Kong Lanlan , Zong Kuikui , Xia Chenying 
Published: January 2025

Abstract
Stretchable conductive yarns have received crucial attention in the direction of wearable electronics. Integration of ordinary yarns with conductive phase endows additional functions such as strain sensing. Herein, highly responsive, stretchable, conductive wrapped yarns with different wrapping densities were prepared, using elastane filament as core, co-wrapped with silver-plated nylon filament (SPNF) and polyester filament. It was found that a wrapping density of 750 T·m−1 was an optimal alternative, taking into account tensile and elastic-related properties, keeping the elastane draw ratio constant. By virtue of the helical-interlaced structure and spiral configuration of wrapping components, the optimized yarn can bear up to nearly 200% strain and exhibit larger-strain cyclic robustness. By incorporating SPNF into the wrapped yarn, it can serve as a stretchable conductor, and it is also able to precisely detect body motion (e.g. finger bending) with high responsiveness (shorter response time). Such functional yarns hold tremendous prospects for wearable electronics.

Authors: Han Jianyong , Liu Dong , Zhang Shengze , Chen Yang , Zhang Yongzhong , Zhao Lijun , He Caishan , Zhao Mingcheng 
Published: January 2025

Abstract
A high geo-stress environment severely damages tunnel structures owing to the large deformation of the surrounding rock, thereby threatening their safety. In this study, the Wushaoling highway tunnel group, which passes through a high geo-stress environment, is investigated as a case study. The spatial distribution of different types of tunnel cracks is analyzed based on the site observations. The lining crack variations, such as circumferential and longitudinal cracks, with the factors including grade of the surrounding rock, location of buried depth, and design type of the tunnel lining are investigated. Various structural reinforcement technologies are presented based on the damage degrees of the tunnel linings. Several finite element models of supporting structures are established to reveal the mechanism of tunnel crack control technology. The results show that longitudinal and circumferential cracks are the main characteristics of tunnel lining damage in high geo-stress environments, accounting for approximately 29.4 and 53.2% of the total cracks, respectively. SIVb-, SVc-, and SVd-type linings show numerous longitudinal cracks per kilometer. The longitudinal cracks appear primarily on the tunnel crown and hance. In terms of the lining support types in Grade V surrounding rocks, the number of longitudinal cracks per kilometer increases with the lining grade. The number of tunnel cracks per kilometer tends to increase with the buried depth. Four tunnel structure reinforcement treatment measurements for lining cracks in high geo-stress condition were innovatively proposed, which were proved effective in deformation controlling and strengthening the tunnel lining using numerical investigation. The key contribution of this research is to reveal the characteristics and evolution mechanism of tunnel lining cracks in high geo-stress condition, and provide effective treatments for the tunnel lining cracks. In addition, the findings from the study on the tunnel lining cracks also provide industry practitioners with a comprehensive guide regarding the characteristics and control techniques of the tunnel lining cracks, which can serve as a steppingstone to facilitate the construction technology development of the transportation industry.

Abstract
This study commences by delving into B-spline curves, their essential properties, and their practical implementations in the real world. It also examines the role of knot vectors, control points, and de Boor’s algorithm in creating an elegant and seamless curve. Beginning with an overview of B-spline curve theory, we delve into the necessary properties that make these curves unique. We explore their local control, smoothness, and versatility, making them well-suited for a wide range of applications. Furthermore, we examine some basic applications of B-spline curves, from designing elegant automotive curves to animating lifelike characters in the entertainment industry, making a significant impact. Utilizing the de Boor algorithm, we intricately shape the contours of everyday essentials by applying a series of control points in combination with a B-spline curve. In addition, we offer valuable insights into the diverse applications of B-spline curves in computer graphics, toy design, the electronics industry, architecture, manufacturing, and various engineering sectors. We highlight their practical utility in manipulating the shape and behavior of the curve, serving as a bridge between theory and application.

Published: January 2025

Abstract
The processes of objectification of rational and irrational types of knowledge in the cultural semantics of toponyms as a product of the mental activity of the subject (individual and ethnolinguistic collective) are considered. The analysis is carried out on the material of toponyms that involve colour values, numerals and phytonyms, mythonyms, etc. The rational type of knowledge contains rich empirical information with diverse cultural semantics. The irrational type of knowledge represents mythological, esoteric, animistic, religious ideas, superstitions, customs, and various folk beliefs with profound ethnosemantics. In rational knowledge, various aspects of the economic and practical life of nomads in the development of the surrounding reality are detailed. The irrational type of knowledge concentrates on value orientations, stereotypes and prejudices, and moral and ethical norms of the nomadic Kazakh ethnic community in the past, represented in the cultural semantics of the language matrix of folk geographical names. For the first time, the ethnoecological, ethnobotanical knowledge of the Kazakh people is presented in the language matrix of toponyms, in which the emphasis is shifted not to lexical features, but to the cultural aspect, to cultural semantics.
Liquid gold: assessing groundwater quality at the historic Kolar gold fields, Karnataka, India
Authors: Paulose Jojo , Xavier Jobi 
Published: January 2025

To access the ecological sustainability and resilience, it is necessary to periodically examine various ecological properties in areas with high pollution and contaminant risks. Kolar Gold Fields (KGF) in Kolar, Karnataka, showcases one amongst the India's most contaminated zones because of the extensive gold mining and their lingering effects. In KGF, quality of ground water has severely reduced as there exist extensive mining tailings, locally referred as cyanide dumps, which have been neglected for several preceding years without proper disposal strategies. The current approach focuses on the water pollution caused by heavy metal deposits in the KGF region. Groundwater samples were sampled from Oorgam, an abandoned region in KGF, and subsequently filtered for water quality examinations. The investigation documented concentrations of several metals, including cadmium (0.068 ± 0.0024 ppm), lead (0.288 ± 0.0016 ppm), nickel (0.058 ± 0.0047 ppm), and chromium (0.23 ± 0.0235 ppm) and have met the standard specifications in accordance with World Health Organization (WHO). Prominent pH disparity was documented amongst the experimental samples, with a detectable pH drop in the aqua-purified water on comparison to the positive control. The test results imply that the water samples collected from KGF remains unpotable for consumption or irrigation due the persistence of high levels of heavy metals concentration. This study underscores the urgent requisite for remedial approach to ensure water safety for drinking and irrigation in the area.
Soil magnetic susceptibility analysis as an indicator of landslide-prone areas in Sanggau Regency, West Kalimantan Province, Indonesia
Authors: Muhardi  , Perdhana Radhitya 
Published: January 2025

Sanggau Regency is a highland area that has a rough topography with a relief of undulating hills, causing the potential for landslides. One of the steps to reduce the impact of landslides is to identify the characteristics of landslide-prone areas by conducting magnetic susceptibility analysis in landslide-prone areas. This analysis is a method to identify landslide indicators based on their magnetic properties. This method identifies landslide potential through superparamagnetic grains on the surface soil. The presence of the grain can be known from the frequency-dependent susceptibility . The study was conducted on 40 soil samples taken at a 20-30 cm depth at Jalan Sabang Merah, Sanggau Regency. The results showed that the average values of low-frequency and high-frequency were 5.555 cm3/g and 5.478 cm3/g, respectively. A total of 36 soil samples have a percentage of 0% (containing less than 10% superparamagnetic grains), two soil samples have a percentage of 3.51% and 6.45%, respectively (containing 10%-75% superparamagnetic grains, and two samples have a percentage of 10.48%-12.63% (containing more than 75% superparamagnetic grains). The interpretation results show that soil samples with more than 75% superparamagnetic grains indicate landslide-prone areas in the study site; thus, the areas suspected to have a high level of vulnerability are in the northeastern and southwestern parts of the study site.

A Proposed Conceptual Model for Examining Acceptance of Corporate Massive Open Online Courses (MOOCs): Integrating Social Support and Sense of Belonging in Technology Acceptance Model (TAM)
Authors: Buyut Veronica Clement , Abdullah Salfarina , Abdullah Rusli , Atan Rodziah 
Published: January 2025

MOOCs, or massive open online courses, have become increasingly popular in the last several years to offer employees online training and development opportunities. Traditional methods of training, such as in-house or external trainings, frequently provide several obstacles, including high prices, logistical complications, and time limits. MOOCs have leveled the playing field in online learning by making quality education available to everyone, especially working adults, allowing them to reskill and upskill their work abilities by offering scalable, flexible, and cost-effective alternatives to address issues encountered in traditional methods of training. Even though MOOCs have been the subject of extensive research in educational institutions, there has been relatively little investigation on the acceptance of MOOCs at the organizational level, particularly among employees. The main challenges with MOOCs are their low completion rates and high dropout rates. This research aims to fill a gap in the literature by providing a Corporate MOOCs acceptance model to assess the possibility of employees using MOOCs in corporate settings for reskilling and upskilling. The proposed model was formulated using the Technology Acceptance Model, Social Support Theory, and Theory of Belongingness as the foundations, besides extending the model with four additional constructs: perceived credibility, perceived convenience, digital competence, and perceived learning. Recommendations for conducting empirical research on the model are provided on how the model will be assessed to be successfully used in measuring employees’ acceptance of Corporate MOOCs.

Published: January 2025

Artificial intelligence (AI) has been integrated into various fields, accelerating innovation in existing ones. Consequently, AI has been employed in education to drive changes such as learning analytics and personalized learning. Recently, the development of generative AI has further transformed the educational landscape. Given the increasing use of generative AI in education, this study was conducted to explore its educational applications. We developed an educational program incorporating generative AI based on design thinking principles for high school students. To verify its effectiveness, high school students in Korea were selected as research subjects and divided into an experimental group (n=53) and a control group (n=42). A test tool aligned with the 2022 revised curriculum in Korea measured computational thinking skills. The study results showed that the group receiving AI convergence education using generative AI significantly improved their computational thinking. The improvement in computational thinking was also significant compared to the control group, providing strong evidence of the benefits of AI in education. This study confirmed that AI convergence education, utilizing generative AI grounded in design thinking, effectively develops computational thinking skills in high school students. The findings of this research highlight the potential educational value of integrating generative AI into both AI design thinking and convergence education. The study provides reassurance that generative AI can be a powerful tool in enhancing student learning experience and outcomes, paving the way for future educational innovations.
