DECISION-MAKING IN THE FIELD OF IMPROVING DIGITAL SERVICES BASED ON CUSTOMER EXPERIENCE (UX): ТHE IMPACT OF USING ARTIFICIAL INTELLIGENCE TECHNOLOGY
Authors: Myagkova K. G. 
Published: August 2024

By conducting UX research, you can reduce user churn in digital services, identify areas of growth, and offer solutions to improve the user experience and retention. The main benefit of UX research is to understand the needs and expectations of users. UX research helps you analyse user’s behavior, preferences and problems of users, as well as determine which features and capabilities of the application are important. The introduction of artificial intelligence (AI) has sparked a discussion about how to improve the design processes associated with UX design, leading to the emergence of the concepts of ‘artificial design intelligence (ADI)’ and ‘intelligent design’.In this article, the author's approach to conducting UX/UI research using AI technology is developed. The current customer path of the banking section in the bank’s mobile application is compiled and modelled. In-depth interviews were conducted with 20 respondents, in which respondents compared screen forms with and without the use of AI technology. UI/UX studies are described based on the in-depth interviews conducted, followed by a justification of the need to implement AI technology to personalise the user path in a mobile application.In addition, the results of the UI/UX study confirmed the hypothesis that the introduction of a personalised user experience using AI technology (photorealistic images of cars) in the bank's mobile application will lead to improved customer satisfaction and increased engagement, which in turn will increase the bank’s profitability and competitiveness.The proposed recommendations will optimise the user experience in the mobile application and improve the NPS and MAU metrics by a factor of 2, according to the experts.

Published: August 2024

Following a period of social isolation from the COVID-19 pandemic, social interactions may be particularly complicated for individuals with elevated levels of social anxiety. One potential implication relates to the use of face masks. Face masks have been used as an effective tool to prevent the transmission of COVID-19. However, for individuals with elevated social anxiety, face masks may be a form of avoidance and type of safety behavior and discontinued use of face masks may be associated with increases in social anxiety. In response to these possibilities, the purpose of this study was to develop a measure to assess potential anxiety-related reactions to face masks. Participants were 564 nonreferred young adults who completed a measure developed for this study to assess behaviors and reactions to face masks (Reaction to Face Masks Questionnaire), including anxiety and avoidance behaviors. Measures of social anxiety, more general avoidance, and safety behaviors were also included. Based on an exploratory factor analysis, a two-factor model was retained. Safety-Seeking and Avoidance (SSA) measures reductions in social anxiety derived from a feeling of safety when wearing a face mask, and Social Interference measures increases in social anxiety symptoms related to the interference/inhibition of social interactions related to wearing masks. Both subscales were found to be associated with general measures of social anxiety, more general avoidance, and safety behaviors; however, the correlations were more robust for the SSA subscale.Based on the current findings, general social anxiety and common correlates of social anxiety, including safety-seeking behaviors, were found to be associated with face mask anxiety and avoidance. Implications for future research and potential clinical practice are discussed.
Necessity of Da’wa Communication for Reformation in Muslim Guardianship Laws in India
Authors: PAZHAYAKATH NAJLA , Kesari A Vani 
Published: August 2024

The diversity of religions, cultures, and languages is an inherent feature of Indian democracy. These kinds of legal pluralism arrangements are found in the area of personal laws in India. Since 1985, India has witnessed a direct conflict between Muslim personal law and secular laws. Recently, one of the High Courts in India reaffirmed that the mother of the child has no right to be considered as the natural guardian of her child. The gender disparities with the guardianship laws under Islamic law are being exposed again by this decision. Inadequate understanding and interpretation of religious texts usually lead to these kinds of disparities. Da’wa can help refresh and reform Sharia by encouraging Muslims to think closely about how it is used and understood and to seek better solutions to today's problems. The guardianship laws in India now need to be changed in light of modern da’wa communication. This article explains the importance of da'wa communication and how it should be applied to reinterpret Muslim personal laws in India. This article concludes with a comment that modern da’wa communication is necessary to interpret guardianship laws under sharia from a liberal dynamic and forward-looking perspective without rejecting the value of Islamic jurisprudence and the All India Muslim Personal Law Board should take measures to achieve gender parity in Muslim guardianship laws through efficient da'wa communication.
Ethnography of Communication: SPEAKING Analysis on Childbirth Services in Sa'dan, North Toraja
Authors: Weny Lestari  
Published: August 2024

This study aims to identify cultural communication gaps in three common childbirth speech events, namely among the Toraja ethnic community in Sa'dan, North Toraja involving childbirth attendants and different locations, namely (1) childbirth attended by a midwife in a healthcare facility, (2) childbirth attended by a to'mappakianak (traditional birth attendant) at the mother's home, and (3) childbirth with collaborative efforts between a midwife and to'mappakianak in a healthcare facility. To pursue the aim of this study, SPEAKING analysis was used. The SPEAKING analysis (Scene/Setting-Participants-Ends-Act-Key-Instruments-Norms-Genre) is a framework in communication ethnography study developed by Dell Hymes to understand and analyse the society and culture of an ethnic group through communication processes. The results indicated that both midwives and to'mappakianak culturally shared the same goal of safely attending childbirth. However, within the context of different speech community's perspectives, the experiences and cultural nuances of participants, including childbirth attendants, mothers, and families, also conveyed different meanings. These differences could be positive or negative for the involved participants. This study could provide insights for policy of maternal and child health service providers to consider cultural and communication factors in health services for Toraja ethnics in Sa'dan, North Toraja. In short, competent childbirth attendants should be culturally communicative and adhere to safe motherhood principles.

Authors: Nian Sunqi , Tang Shaohua , Shen Shiqian , Yue Wenqiang , Zhao Caiwang , Zou Tiannan , Li Weichao , Li Na , Lu Sheng , Chen Jiayu 
Published: August 2024

Background:
Modic changes (MCs), vertebral end plate and bone marrow damage observed by magnetic resonance imaging, are an independent risk factor for low back pain. The compositions of and interaction between microbiota and metabolites in the lumbar cartilaginous end plates (LCEPs) of patients with MCs have not been identified.

Methods:
Patients with lumbar disc degeneration who were undergoing lumbar spinal fusion surgery were recruited between April 2020 and April 2021. LCEPs were collected for 16S rRNA sequencing and liquid chromatography-mass spectrometry (LC/MS)-based targeted metabolomic profiling. Of the 54 patients recruited, 24 had no MCs and 30 had changes classified as Modic type 2 or 3. The primary goal was to identify specific genera of microbiota associated with MCs, and secondary goals included investigating differences in metabolites between patients with and without MCs and exploring the correlation between these metabolites and microorganisms.

Results:
Investigation of the microbiota community structure revealed that both alpha diversity and beta diversity were significantly different between patients with and without MCs, and the abundances of 26 genera were significantly different between these 2 groups. Metabolomic analysis revealed that 26 metabolites were significantly different between the 2 groups. The unsaturated fatty acid pathway was found to be the main pathway related to MCs. Multiomic correlation analysis suggested that Caulobacteraceae (unclassified) and Mycobacterium, Clostridium, Blautia, and Bifidobacterium at the genus level were linked to dysregulation of fatty acid metabolism, contributing to the pathogenesis of MCs.

Conclusions:
Our study represents a foundational effort to examine the landscape of the microbiota and metabolites in patients with MCs, informing future studies on the pathogenesis of and targeted therapy for MCs.

Radiographic Assessment of Pelvic Inlet and Outlet View Angles in the Ethiopian Population
Authors: Melkamu Solomon , Alemayehu Gabriel , Hailu Samuel 
Published: August 2024

Background:
Accurate radiographic assessment is pivotal in evaluating trauma patients with suspected pelvic ring disruptions. The conventional approach of using anteroposterior, 45° inlet, and 45° outlet radiographs for the evaluation of pelvic injury may not consistently align with varying lumbopelvic anatomy. This study aimed to determine the ideal pelvic inlet and outlet radiographic angles when there is limited access to advanced imaging (e.g., computed tomography [CT]) for assessing clinically relevant pelvic osseous landmarks and to investigate variations based on age, sex, and sacral dysmorphism.

Methods:
This cross-sectional study investigated patients who were ≥18 years of age who had no traumatic injuries or pelvic ring pathology; we reviewed abdominopelvic CT scans that were obtained between January 1, 2023, and June 30, 2023. Midsagittal reconstruction and 3D rendering of 148 CT scans facilitated the measurement of pelvic inlet and outlet angles. Standard techniques that were based on previous studies were used to determine the ideal angles. Statistical analyses investigated mean pelvic inlet and outlet angles as well as correlations with age, sex, and sacral dysmorphism.

Results:
The mean pelvic inlet angle was 23.8° ± 8.4° (95% confidence interval [CI]: 22.4° to 25.2°), and the mean outlet angle was 40.1° ± 5.9° (95% CI: 39.2° to 41.1°). Male patients exhibited greater inlet angles (27° versus 20°), whereas female patients had greater outlet angles (41° versus 39°). Pelves with dysmorphism showed a 3.6° increase in outlet angles when compared with those with normal sacral anatomy. An inverse relationship between age and inlet angle was observed.

Conclusions:
This study highlights that the recommended 45° angle for pelvic inlet and outlet views may not optimally align with the anatomy of the Ethiopian population. The findings suggest that the ideal inlet and outlet angles for this population are 25° and 40°, respectively. Understanding these variations is crucial for optimizing pelvic radiographic views in trauma evaluation, potentially leading to more accurate assessments and improved patient care in this demographic.

ESP Application for High Flow and Deep Wells Using a reduced OD Pump with the Biggest Worldwide Single 562 Series Permanent Magnet Motor Adapting Existing VSD
Authors: Vargas W. Salazar , Archila J. , Perez L. , Muñoz D. , Rodríguez O. 
Published: August 2024

Abstract
A reduced outer diameter (OD) high flow rate pump, a high power permanent magnet motor (PMM) and the most usual Variable Speed Drive (VSD) available in the field were selected. The VSD with minimum capabilities to run the PMM with a "scalar V/Hz" control algorithm were validated. The validation tests were performed in a testing loop where the best parameter configuration was selected to match a proved "vector control" Drive performance from the same motor vendor. Key parameters such as magnetizing current at minimum level were identified.
The system was installed in Tello field, Colombia. It was started and operated without any issues following strict safety procedures and barriers.
This PMM application has delivered energy savings above 15% versus the previous induction motor (IM) application. The energy consumption decreased from 625kWh to 478kWh, 147kWh less, representing a saving of USD 85,000 per year.
The scalar (volts/Hz) control has shown good motor control for the application conditions: high water cut (96%), casing 7" 26#, 8000 ft, deviated well, and rates above 9000 BFPD.
Reliability improvement is established by replacing 990HP induction triple tandem motor (102ft) for a single 980HP Permanent Magnet Motor (34ft). The PMM showed a lower operating temperature and eliminated current peaks during motor start-up. The diameter of the pump was reduced by 0.9" (from 5.38" series pump to 4.49" series pump), providing a faster installation, reducing the risk of MLE damage or ESP equipment stuck due to reduced clearance. The run life of the well increased from less than 6 months to more than 3 years. As expected, this new downhole configuration presented an improvement in reliability compared to conventional ESP equipment.
A second well was installed confirming the benefits of the approach, and the Field Operator Management has approved the PMM massification in the Tello field.
This application proved the option of running and benefiting from reduced OD high flow rate pump and the Permanent Magnet Motor technology utilizing existing surface equipment, facilitating the financial decision, and improving reliability.

Abstract
The conventional sucker rod pump system is comprised of ball and seat-type traveling and standing check valves that use positive displacement to produce oil from the reservoir (Takacs 2015). With the advent of horizontal drilling and fracturing, sucker rod pumps are increasingly landed at greater depths and inclinations from vertical to maximize access to reserves and extend the production life of the well.
This paper builds upon existing downhole vortex valve systems research to test and understand the potential of a vortex fluid flow profile. The Vortex Barbell System (VBS) was designed to establish and elongate a vortex fluid flow profile that sustains fluid velocity in downhole environments. Early field trials with the VBS showed promising capability to land pumps in the curve with production success. This prompted further laboratory testing. The laboratory environment was designed to model downhole fluid conditions and wellbore trajectory. The results were compared to field data from wells running the VBS. The analysis draws connections between laboratory results and field trials to explain how the VBS elongates a vortex flow profile, sustains fluid velocity, and increases pump fillage so that rod pumps can be landed deeper in high inclination wells (in the curve) to retain pump efficiency, increase production, reduce failure frequency, and extend the pump life.
Plunger Fall Velocity for Production Optimization

Published: August 2024

Abstract
Liquid loading is common in high gas-liquid ratio (GLR) wells with low reservoir pressure. Plunger lift is an artificial lift method many operators use to remove liquid accumulation in their wells. It is widely used due to its flexibility and cheap operational cost. Accurate prediction of fall times can help operators maximize production from their wells by reducing unnecessarily long close times. However, many conventional plunger lift systems are run un-optimally because the operators do not completely understand the system’s behavior. This study combined previous literature and experimental work with novel improvements and modeling techniques to develop a new physics-based model for conventional plunger fall velocity. The model’s predictions have been compared with actual plunger fall velocity data from field applications.
