Objectives: This study examines whether psychological empowerment plays a role in job crafting and employee well-being for workers who face horizontal educational mismatches. A horizontal educational mismatch could be defined as a mismatch between the field of education and current occupation. This study shows that horizontal educational mismatches which are increasingly commonplace in society, especially in Indonesia, may affect the well-being of workers. Employee well-being describes the overall well-being of employees, such as physical, psychological, and individual aspects.
Methods: The study’s respondents are 361 Indonesian workers with horizontal educational mismatches. The study’s tools are employee well-being scale (EWBS), job crafting questionnaire (JCQ), and psychological empowerment questionnaire (PEQ). The measuring tools were adapted into the Indonesian language, and data was analyzed by Andrew F. Hayes’s simple regression mediation model no.4 PROCESS v4.0.
Results: The study reveals that psychological empowerment facilitates job crafting and employee well-being for workers with horizontal educational mismatches. It also shows that employees who are psychologically empowered are those who are supported in taking responsibility for enhancing their performance and their contribution to the organization. As a result of the increased demand for productivity, employees must enhance their skills and knowledge to achieve higher job demands instead of simply establishing opportunities for well-being and self-development. That is, workers are given the abilities and resources required to compensate for the shortages caused by the horizontal educational mismatch they face.
Conclusions: This study fills in a research gap by shedding light on the indirect effect a horizontal educational mismatch might have on workers’ competence and will-being.

RESPONSIVENESS OF WOMEN’S UNPAID WORK TO FAMILY DEMOGRAPHICS IN TRIBAL AND NON-TRIBAL AREAS OF INDIA
Authors: KUMARI Poonam
Published: May 2024

Across the globe, women are mostly in charge of working in the fields, providing unpaid care, which includes housekeeping and providing care for others in their homes and communities without receiving any specific financial compensation. The present study is aimed at assessing the significance, nature and size of the responsiveness of women’s unpaid work to the various demographic characteristics of families in the tribal and non-tribal areas of India. The impacts of different variables on SNA, ESNA, NSNA, and overall unpaid work of tribal and nontribal women were separately investigated. The Multiple Linear Regression Model was applied using the Microsoft Office Excel Analysis ToolPak. The findings suggest that women are engaged in SNA activities regardless of the family’s demographic structure in both tribal and non-tribal areas. However, the participation of non-tribal women in ESNA activities is more complex and requires further study compared to tribal women. The involvement of tribal and non-tribal women in NSNA activities is influenced by factors beyond demographic variables (except age), such as psychological, social, and cultural factors. In case of the overall unpaid work burden, the impact of the same factors (except for the number of family members) on unpaid work differs between tribal and non-tribal women. However, education demonstrates a strong positive and significant impact on reducing unpaid work burden across both groups.

Published: May 2024

Pos pembinaan terpadu Penyakit Tidak Menular (Posbindu PTM) merupakan program pemberdayaan masyarakat dalam upaya pencegahan dan deteksi dini kasus-kasus PTM dengan sasaran kelompok masyarakat berusia 15 tahun ke atas. Sampai saat ini pelaksanaan posbindu PTM di 20 wilayah kerja puskesmas Kota Bengkulu belum tepat sasaran, hal ini terlihat dari partisipasi masyarakat yang berkunjung ke Posbindu PTM didominasi oleh kelompok usia di atas 47,59 tahun. Penelitian ini melihat dengan aktifnya peserta mengikuti kegiatan Posbindu PTM akan berbanding lurus dengan menurunnya tingkat kunjunagn berobat ke Puskesmas. Tujuan penelitian keaktifan kunjungan peserta Posbindu PTM terhadap kunjungan pengobatan di Puskesmas Kota Bengkulu. Desain penelitian ini adalah eksploratori dengan pendekatan observasional Cross Sectional dengan uji hipotesis untuk mengetahui hubungan kunjungan Posbindu PTM terhadap kunjungan pengobatan ke Puskesmas dan metode kualitatif untuk mengetahui implementasi program Posbindu PTM. Sampel penelitian berjumlah 136 orang dengan teknik Accidental Sampling. Uji validitas dan reabilitas instrument pada peserta aktif Posbindu pada Kabupaten Bengkulu Tengah dan pada peserta bukan Jaminan Kesehatan Nasional.   Hasil penelitian menunjukan tidak terdapat pengaruh kunjungan program Posbindu PTM terhadap kunjungan pengobatan ke puskesmas Kota Bengkulu (p = 0,629). Sejalan dengan peserta posbindu PTM berusia 47,59 tahun ke atas tidak ada pengaruh kunjungan peserta terhadap kunjungan sakit. Analisis implementasi program Posbindu PTM sudah berjalan sesuai SOP dengan kegiatan yang sangat dirasakan bermanfaat bagi peserta terutama dalam hal pemantauan status kesehatan. Namun, masih rendahnya partisipasi masyarakat dalam mengikuti kegiatan Posbindu karena  pelaksanaannya yang mayoritas dilakukan pada saat jam kerja, sehingga sasaran kegiatan didominasi oleh kelompok lansia. Permasalahan lain adalah kurangnya pemahaman masyarakat tentang Posbindu PTM yaitu dengan kegiatan yang dibatasi oleh pemeriksaan kesehatan saja tanpa adanya kegiatan pengobatan lebih lanjut. Diharapkan adanya koordinasi dari pihak puskesmas dan kader dalam mengkomunikasikan mengenai pentingnya program Posbindu PTM kepada masyarakat sebagai upaya meningkatkan kesadaran masyarakat dalam pencegahan dan pemantauan status kesehatan.

Published: May 2024

The foundations of nonlinear optics are revisited, and the formalism is
applied to waveguide modes. The effect of loss and dispersion are
included rigorously along with the vectorial nature of the modes, and a
full derivation of a new version of the nonlinear Schrödinger (NLS)
equation is presented. This leads to more general expressions for the
group index, for the group-index dispersion (GVD), and for the Kerr
coefficient. These quantities are essential for the design of waveguides
suitable for e.g. the generation of optical frequency combs and
all-optical switches. Examples are given using the silicon nitride
material platform. Specifically, values are extracted for the
coefficients of the chi-3 tensor based on measurements of Kerr
coefficients and mode simulations.
5G Positioning: Advantageous Aspects, Taxonomy, State-of-the-art Review and Future Trends
Authors: Sadhukhan Pampa , Mukherjee Nandini , Das Pradip K
Published: May 2024

5G positioning is an essential part of many applications, such as
driverless vehicles, drone tracking, emergency services, location-based
services, etc. Such positioning can attain an accuracy on the order of 1
meter or even lower in both indoor and outdoor settings due to its
several advantageous aspects, which include millimeter wave signal,
multiple input multiple output antennas, device-to-device communication,
etc. Hence, many researchers have paid attention to the development of
5G positioning systems over the past decade. This paper, therefore,
presents a state-of-the-art review of the existing 5G positioning
methods along with their taxonomy and comparative analysis in several
metrics including their merits and demerits. Moreover, the architecture
and advantageous aspects of 5G positioning are also presented in this
paper. Similar to the satellite signals, 5G signals, however, can be
impeded by various obstructions, further declining the accuracy of such
positioning. Moreover, many security concerns and privacy issues are
also associated with 5G positioning. Thus, the development of a precise
and secure 5G positioning system faces a number of challenges.
Therefore, various ways to improve the 5G positioning accuracy and
several solutions to address the security concerns and privacy issues of
such positioning are pointed out in this study.
Optoelectronic Shape Sensing for Flexible Robotic Applications
Authors: Osman Dalia , Noh Yohan
Published: May 2024

Shape sensing in continuum robotics enables stable actuation and control, as estimation of complex curvatures is essential for manoeuvring through complex environments, for applications in the manufacturing, aerospace, and medical industries, as well as space and rescue operations. This paper demonstrates the performance of an optoelectronic based shape sensing system integrated into a two-segment tendon actuated robotic manipulator. The sensing principle is proximity-intensity based sensing and utilises a convex shaped reflector for modulation of proximity during rotation in two degrees of freedom. For improved sensing performance, the shape sensing system utilises a simplified circuit design with features such as power switching properties for elimination of signal interference effects and for significant reduction in consumption of power, as well as inclusion of low friction tubes along the tendon routing paths, for reduced friction during large bending motions. A new streamlined technique for the calibration of the sensors is demonstrated, and a validation of the shape sensing performance shows improved estimates of tip position and orientation as well as shape of the robotic structure.

Authors: Banerjee Sheekar , Kabir Humayun
Published: May 2024

Robot Vision is the technique of enabling robots to process visual data
from the environment by utilizing a combination of camera hardware and
computer algorithms. Advanced deep neural networks have significantly
played a vital role in indulging robots to make more sense out of
complex visual data at different circumstances, especially in object
detection and continuous tracking. In this research, we initiated a
unique and cutting-edge backbone neural network for the conventional
YOLO algorithm which we named as SBHK-Net. The network boosted up the
performance of the existing YOLO algorithm drastically which manifests a
strong potential of improving tracking and recognition accuracies of
other conventional algorithms in the robot vision industry as well. It
has the greatest accuracy 59.2% AP among all known real-time object
detectors with 30 FPS or above on GPU RTX3060, and it outperforms all
other known object detectors in the range of 5 FPS to 160 FPS. We used
YOLOv7 as our reference point for the core research. The
transformer-based detector SWINL Cascade-Mask R-CNN (9.2 FPS A100,
53.9% AP) and the convolutional detector ConvNeXt-XL Cascade-Mask R-CNN
(8.6 FPS A100, 55.2% AP) are both outperformed by the SBHK-Net core
object detector (56 FPS RTX3060, 56.4% AP) in terms of speed and
accuracy, respectively. In terms of speed and accuracy, it surpasses a
number of other object detectors, including DINO-5scale-R50,
ViT-Adapter-B, Scaled-YOLOv4, YOLOv5, DETR, Deformable DETR, and YOLOR
and YoLOX. The source code of this research is available at

Advanced 4.0 Bed Management System, embedded with IoT, Digital Twins and, Cyber Physical System
Authors: Mosca Marco , Mosca Roberto , Briatore Federico
Published: May 2024

Objective: the paper aims to address the surveillance of long-term
bedridden patients. Although often necessary, continuous monitoring
cannot be carried out due to cost constraints and limited personnel
availability. Current solutions involve wearable devices and cameras,
but they have limitations, as discomfort and concerns about privacy.
Method: firstly, a thorough review of existing literature has been
carried out. Then, it was developed the innovative system, focusing on
bed monitoring instead of direct patient control. After identifying
necessary patient condition data, various sensors were tested. To
leverage data potential, the authors explored methods of centralizing
and analyzing information. A platform was designed to assist operators
in anticipating accidents. Finally, Digital Twins and Cyber Physical
Systems were considered for their potential value in the system.
Results: The proposed system monitors patient’s bed without direct
contact, in contrast to wearable devices. This innovative approach
utilizes applied sensors capable of identifying risky behaviors, signs
of specific pathologies, unusual movements, tremors, or abnormal
humidity in the bed. The benefits include improved service levels,
reduced operator surveillance, freeing up time for value-added
activities, timely intervention where necessary, prevention of bed falls
and sores, detection of wet beds, enhancement of sleep quality, and
monitoring of weight trends. Conclusions: Literature indicates that lack
of bed surveillance in healthcare is a global issue expected to worsen
due to the progressive aging of the population. Authors’ 4.0 solution
can effectively address this problem, improving service levels by
monitoring and simulating patient behavior rather than direct
monitoring, thus minimizing patient discomfort.
Mixed Redundancy Strategy for Medium Voltage Modular Multilevel Converters Using Active Submodules in Combination with Standby Spares
Authors: Ahmadi Miad , Shekhar Aditya , Bauer Pavol
Published: May 2024

Modular Multilevel Converter (MMC) is favorable for high-power
grid-connected power electronic applications to achieve efficient
operation. The required number of components significantly increases
when higher modularity is introduced for the given voltage level, thus
reducing the system reliability. This paper suggests a Mixed Redundancy
Strategy (MRS) that combines the operational concepts using active and
redundant spare sub-modules. It is shown that more than 50 % higher
B = 10 lifetime is achievable as compared to
reliability improvement using Fixed-Level Active (FL-ARS), Load-Sharing
Active (LS-ARS), and Standby Redundancy Strategy (SRS) with the same
number of redundant submodules. The trade-off between operational
efficiency and investment cost is explored to define the boundary for
selecting MRS over other redundancy strategies with varying dc-link
voltages and average converter loading considering a 10-year payback
period and equivalent B = 10 lifetime. The results are
discussed for two case studies using load profiles adapted from
available data from a medium voltage substation. The change in viability
boundary for MRS is established with increasing B = 10
lifetime and its sensitivity to power electronic component cost as well
as assumed failure rate.
DAO-FL: Enabling Decentralized Input and Output Verification in Federated Learning with Decentralized Autonomous Organizations
Authors: Majeed Umer , Hassan Sheikh Salman , Han Zhu , Hong Choong Seon
Published: May 2024

In the rapidly evolving landscape of Web3 and blockchain technologies,
decentralized autonomous organizations (DAOs) have emerged as innovative
structures that operate autonomously through blockchain and smart
contracts, eliminating the need for centralized control. The federated
learning (FL) process, akin to an information flow under structured
transparency, involves local models (LMs) as inputs and the global model
(GM) as the output for each global iteration. The lack of transparency
and security in traditional FL systems can be attributed to the
centralized validation of LMs and GM updates. In this paper, we propose
DAO-FL, a smart contract-based framework that leverages the power of
DAOs to address these FL challenges. DAO-FL introduces the concept of
DAO Membership Tokens (DAOMTs) as a governance tool within a DAO. DAOMTs
play a crucial role within the DAO, facilitating members’ enrollment and
expulsion. Our framework incorporates a Validation-DAO for decentralized
input verification (DIV) of the FL process, ensuring reliable and
transparent validation of LMs. Additionally, DAO-FL employs a
multi-signatures approach facilitated by an Orchestrator-DAO to achieve
decentralized GM updates, and thus decentralized output verification
(DOV) of the FL process. We present a comprehensive system architecture,
detailed execution workflow, implementation specifications, and
qualitative evaluation for DAO-FL. Evaluation under threat models
highlights DAO-FL’s out-performance against traditional centralized-FL,
effectively countering input and output attacks. DAO-FL excels in
scenarios where DIV and DOV are crucial, offering enhanced transparency
and trust. In conclusion, DAOFL provides a compelling solution for FL,
reinforcing the integrity of the FL ecosystem through decentralized
decision making and validation mechanisms.

In dit hoofdstuk plaatsen de auteurs het oefenen van een democratische houding in het kader van de maatschappelijke taak van de kinderopvang. Die taak krijgt – naast de economische en de pedagogische functie – veel aandacht in de sector. Zo boog een groep van betrokken mensen uit de kinderopvangsector zich over de pedagogische en maatschappelijke opdracht die de samenleving aan de kinderopvang stelt. Deze Initiatiefgroep Context Kinderopvang stelde een manifest op waarin staat dat kinderopvang bijdraagt aan de ontwikkeling van kinderen tot evenwichtige leden van de samenleving en aan de opvoeding van kinderen tot democratische burgers. Kinderen hebben – naast het recht op zorg en bescherming – ook recht op deze maatschappelijke voorbereiding. De kinderopvang is volwaardig opvoedpartner in de driehoek gezin-school-kinderopvang en biedt kinderen een veilige plek om zich te ontplooien, hun voorkeuren te ontdekken en zich sociaal te ontwikkelen. Het is de maatschappelijke opdracht van de kinderopvang om in de opvoeding aandacht te besteden aan het algemeen belang, om de grondbeginselen van de democratie veilig te stellen. Hoewel de verantwoordelijkheid voor de opvoeding van kinderen primair ligt bij hun ouders, hebben ook andere volwassenen om het kind heen hierin hun taak. Omdat meer dan 90 procent van de kinderen gebruikmaakt van een vorm van formele kinderopvang, heeft de kinderopvang een verantwoordelijkheid tegenover ouders, kinderen en maatschappij. Die krijgt vorm in een volwaardige vervangende opvoedomgeving die ouders in staat stelt te werken en hen waar nodig steunt of adviseert bij de opvoeding. Kinderen vinden in kindercentra een veilige omgeving waar ze verbindingen kunnen aangaan met anderen en leren deelnemen in een democratische leefgemeenschap. Kindercentra opereren hierbij niet solistisch, maar in hun lokale en regionale context en in samenwerkingsverbanden met bijvoorbeeld onderwijs en jeugdzorg.

In this study, the malachite green adsorption process using Amberlite IRC-748 and Diaion CR-11 resins was modelled by artificial neural network method. In the model created for this study, adsorbent dosage, initial malachite green concentration and contact time parameters, which are the independent variables of the adsorption process, were used as input. Adsorption percentage values, which are the dependent variables of the adsorption process, were obtained as output. Mean squared error (MSE) and determination coefficient (R2) values were obtained from the models created using thirty-one experimental data for adsorption of malachite green with Amberlite IRC-748 and thirty-eight experimental data for adsorption with Diaion CR-11. By evaluating these values together, the most appropriate training algorithm, transfer function in the hidden layer and the number of neurons in the hidden layer were defined. Accordingly, for both Amberlite IRC-748 and Diaion CR-11 resins, the optimum training algorithm was determined as Levenberg-Marquardt back-propagation and the optimum hidden layer transfer function as tan sigmoid. The optimum number of neurons in the hidden layer was identified as 13 for Amberlite IRC-748 and 12 for Diaion CR11. The MSE, R2all and R2test values of the models produced with the optimum parameters were obtained as 0.000261, 0.9972, 0.9903 for Amberlite IRC-748 and 0.000482, 0.9932, 0.9931 for Diaion CR11, respectively.

Authors: Langie Roycke Harry
Published: May 2024

Trafficking in Persons is unarguably one of the largest crime industries in the 21st century that demand a concrete and comprehensive legal policy approach. However, as it turns out into practice, trafficking in persons is a low-risk, high-reward form of crime. This is qualitative research using a statutory approach, case and conceptual approaches. The primary legal materials resulted from relevant laws and legislation. The legal material collected is analysed prescriptively. The results showed that the Indonesian National Police's resource support in eradicating the Crime of Trafficking in Persons is currently still inadequate in terms of human resources, budget support, and facilities and infrastructure support. Anticipating the impact of low economic growth in Indonesia and limited employment opportunities in the country resulting in many Indonesians being forced to work abroad. The ideal model (role model) offered is measured based on the establishment of reciprocal cooperative relations between countries will become easier and smoother to support the success of eradicating the crime of trafficking in persons. Realizing the acceleration of settlement times for cross-border Criminal Trafficking in Persons cases. Realizing increased communication and exchange of information related which is useful in preventing and enforcing the law, as well as resolving problems between countries.
"Cardiac Ion Channels: Insights into Mechanisms and Modulation"
Authors: N Poornima , Shabi Mohamed M , Biju Liya , Zuber Md , S Shoaib Pasha
Published: May 2024

Ion channels play crucial roles in cardiac function, regulating the flow of ions across cell membranes in response to various stimuli. These proteins exhibit selective permeability to specific ions such as Na+, K+, Ca++ and Cl− and their gating mechanisms can be voltage-dependent, ligand-dependent, or mechano-sensitive. Sodium channels, for example, are essential for cardiac action potentials and are implicated in various heart pathologies. Mutations in these channels can lead to situations like long QT syndrome and Brugada syndrome. Calcium channels are vital for excitation-contraction coupling, and L-type channels are predominant in cardiac myocytes. They regulate calcium influx, which is crucial for myocardial contraction. T-type channels, although less prevalent in hearts, contribute to pacemaker activity and may influence heart rhythm. Potassium channels, including voltage-gated and inward rectifier channels, are crucial for maintaining the resting membrane potential and regulating action potential duration. Dysfunction of potassium channels are associated with arrhythmias and cardiac pathologies like long QT syndrome. Additionally, the Na+-K+ pump maintains cellular ion gradients essential for various physiological processes. Understanding the structure and function of these ion channels provides insights into cardiac physiology and pathophysiology, guiding the development of targeted therapies for heart disorders.
Design of an Internet of Things (IoT) based Early Fire Prevention System Due to LPG Gas Leakage Using NodeMCU ESP8266 Module
Authors: Atmiasri Atmiasri
Published: May 2024

Gas is a molecule that is unbound, shapeless, invisible, and can transform into liquid or solid forms. Liquified Petroleum Gas (LPG) has become a part of people's lives, especially in cooking, and there are many benefits to using LPG. However, there are dangers posed by leaks of LPG gas that can lead to house fires. Improper installation of regulators is one such risk. Preventive measures against fire hazards caused by leaks can be anticipated by using the design and construction of an Early Warning System for LPG Gas Leaks based on the Internet of Things (IoT) using the Blynk application with the NodeMCU ESP8266 module. This device is equipped with an MQ-2 sensor, a relay, a 12V DC fan, and the Internet of Things. The system works as follows: when the MQ-2 sensor detects the presence of LPG gas, the relay turns on the fan, which will remove the gas from the vicinity of the open flame on the stove. The system can be monitored through the Blynk IOT application, which also provides notifications
Embracing Plural Curricula Amid Neoliberalism in Contemporary Universities in Africa: Asante’s Afrocentric Idea Revisited
Authors: Nyoni Phefumula , Chiramba Otilia
Published: May 2024

This paper focuses on how Asante’s idea of Afrocentricity could assist in the understanding of the main challenges andopportunities associated with curricula in Africa’s post-colonial universities. In terms of methodology, the paper constitutes a conceptual treatise that draws from previous empirical research that focused on Afrocentricity and a plural programme – the extended curriculum programme within a university context where neoliberalism remains dominant. In this regard, the paper combines an extensive review of empirical cases and the authors’ experiences of the extended curriculum programmes in diverse South African universities. Literature was reviewed from a wide range of sources that included Afrocentricity and curriculum transformation through plurality at individual and institutional pedagogic levels. The paper explores the complex nature of pedagogic transformation mainly due to the persistence of Western ideals under a resurgent neoliberal philosophy that shapes practices in contemporary university spaces. The paper thus highlights how Afrocentricity transcends simplistic notions of intellectual discussions as it highlights seriousand practical realities that shape the identities, ideals, aspirations, and values of students from disadvantaged backgrounds. In the process, ways in which pedagogic educational aspirations of the students could be redefined through an Afrocentric approach together with constraints are discussed. The individualist-oriented complications posed by neoliberal ideals that tend to contradictand, in some instances, hinder the Afrocentric core principle of inclusivity have left African universities at a crossroads with little to show in terms of progress in the transformation agenda.

The articles in this Special Issue were selected from responses to a call for abstracts on the theme “Generation of African Scholars andthe Intellectual Legacies”. The idea was originally conceived by the late Professor Michael Cross, pioneer Director of the Ali Mazrui Centre for Higher Education Studies (AMCHES), University of Johannesburg, South Africa, to be a flagship project of the budding centre. It aimed to bring together, outstanding scholars from diverse disciplinary backgrounds and perspectives to critically investigate, analyse and document the intellectual legacies of African scholars, leaders, and institutions. Its central objective was to analyse the nature of African scholars’ contributions to knowledge production with the specific goal of influencing and/or shaping the higher education landscape, discourses, policies, and practices in Africa.
