Contextual barriers to implementing pandemic HRM in Indian manufacturing SMEs: A comprehensive analysis
Authors: Subramanian Nagamani , Suresh M. , Shah Bhavin
Published: August 2024

BACKGROUND: Existing literature lacks in-depth analyses and identification of barriers to implementing HR practices that affect employee health and well-being, especially during and after the pandemic. Moreover, existing studies primarily focus on large organizations with generic HR contexts. Therefore, this research contributes by evaluating the contextual relationship between barriers to implementing pandemic Human Resource Management (HRM) practices in Indian manufacturing SMEs. OBJECTIVE: The post-pandemic landscape has necessitated a reevaluation of Human Resource (HR) practices, particularly in terms of employee health and well-being while balancing organizational performance goals. This study seeks to identify and evaluate the significant barriers hindering the implementation of re-designed HR policies, focusing on Small and Medium-sized Enterprises (SMEs) in the manufacturing sector in developing countries during and after the pandemic transition. METHODS: The study initially identified ten barriers through a thorough literature review, which was then validated by experts. Subsequently, the interrelationships among these barriers were explored, and their structural hierarchy was established using the Total Interpretive Structural Modelling (TISM) approach. Additionally, a MICMAC (Matriced Impact Croises Multiplication Applique) analysis was performed to assess the driving-dependence power of each barrier. RESULTS: “Manager’s resistance to change” and “employee’s resistance to change” were found to be highly dependent on the other identified barriers. Among these, “lack of skilled managers at affordable costs” and “implementation expenses of new normal HRM practices” emerged as the most critical barriers, with the potential to impact all other barriers in the implementation of re-designed policies. CONCLUSIONS: The study helps owners of manufacturing SMEs and managers to understand the significant barriers to implementing HR policies, particularly in frequent pandemic situations for enhancing employees’ health and well-being while ensuring organizational performance. The planned framework might make it easier for practitioners and decision-makers to comprehend how the various implementation barriers relate to one another. The study’s focus on Indian manufacturing SMEs limits the generalizability of findings to other contexts. Reliance on expert opinions introduces bias, and further validation through empirical research is needed.

Authors: Ashfaq Fouzia , Abid Ghulam , Ilyas Sehrish , Faseeh Ahmed
Published: August 2024

BACKGROUND: The current challenging time necessitates looking beyond designated, traditional, and role-based sources of leadership and instead looking at a range of more inclusive leadership styles. This is the first endeavor to investigate how a sustainable leadership style drives work engagement by mediating the effects of perceived organizational support and mental health. These factors generate unique pathways yet to be assessed in the literature. OBJECTIVE: Drawing on the conservation of resources theory, our study strives to analyze a sequential mediation framework for employee engagement under the influence of sustainable leadership along with the mediating effects of perceived organizational support and mental health. METHODS: Data collection was performed during COVID-19 at different times, with an interval of three weeks, from 365 healthcare workers in Pakistan’s private and public sector hospitals. Data analysis was performed using SEM and PROCESS Macro by Hayes. RESULTS: The study reveals that in overcoming challenges like COVID-19, perceived organizational support and a health worker’s mental health play a vital role in explaining the association between sustainable leadership style and work engagement. CONCLUSION: The findings of the current study will inspire the administration of healthcare institutions to invest resources that foster a supportive environment for their workers by employing sustainable leadership practices, reducing the effects of overwork and pressures faced by frontline workers during the COVID-19 pandemic. If healthcare workers are left on their own to tackle the challenges of the pandemic, disengagement, which leads to higher absenteeism and lower productivity, may topple the whole system.

Authors: Gutierrez Johnny , Kurz Carolin , Sandoval Cosme , Edmonds Rose , Bittner Tobias , Perneczky Robert , Biever Anne
Published: August 2024

Background:

Studies comparing cerebrospinal fluid (CSF) and plasma complement proteins in Alzheimer’s disease (AD) patients versus healthy controls (HC) have yielded inconsistent results. Discrepancies in the preanalytical sample handling could contribute to the heterogeneity in the reported findings.

Objective:

Using qualified immunoassays, we aimed at assessing the impact of preanalytical procedures on complement proteins in blood and CSF from AD patients and HCs.

Methods:

We supplemented HC and AD CSF/plasma with complement stabilizers and measured the complement proteins C4a, C4, C3a, C3, Factor Bb and Factor B by immunoassay. We tested the impact of freeze-thaw (FT) cycles on fluid complement proteins.

Results:

Most complement proteins were mildly impacted by FT cycles in plasma but not CSF, except for C3a which displayed greater sensitivity to FTs in CSF than in plasma. In CSF, the effect of FTs on C3a was reduced but not prevented by the supplementation with EDTA (±Futhan).

Conclusions:

Our findings provide recommendations for CSF/plasma sample handling to ensure robust and reproducible complement biomarker analyses in AD.

Published: August 2024

Background: Cognitive impairment is a clinical manifestation that occurs in the course of dementia like Alzheimer’s disease. The association between cognitive impairment and gut microbiota is unclear. Objective: We aimed to identify gut microbiota characteristics and key gut microbiota biomarkers associated with cognitive impairment in a relatively large cohort of older adults in China. Methods: A total of 229 adults aged ≥60 years from Shenzhen, China were recruited into this cross-sectional study. Participants were divided into cognitive impairment (CI) and no cognitive impairment (NCI) groups according to the results of the Mini-Mental State Examination. Diversity analysis and network analysis were used to characterize the gut microbiota between the two groups. The linear discriminant analysis effect size method and machine learning approaches were sequentially performed to identify gut microbiota biomarkers. The relationship between biomarkers and lifestyle factors was explored using Transformation-based redundancy analysis (tb-RDA). Results: A total of 74 CI participants and 131 NCI participants were included in the analysis. The CI group demonstrated lower α-diversity compared to the NCI group (Shannon: 2.798 versus 3.152, p < 0.001). The density of the gut microbiota interaction network was lower in the CI group (0.074) compared to the NCI group (0.081). Megamonas, Blautia, Pseudomonas, Stenotrophomonas, and Veillonella were key biomarkers for CI. The tb-RDA revealed that increased fruit intake and exercise contribute to a higher abundance of Megamonas, Blautia, and Veillonella. Conclusions: We identified a significantly reduced abundance of certain beneficial gut microbiota in older Chinese adults with cognitive impairment.
Causal Effects of Kidney Function and Chronic Kidney Disease on Alzheimer’s Disease by Analyzing Large-Scale Genome-Wide Association Study Datasets
Authors: Zhao Hainan , Yuan Hongxia , Wang Ermin
Published: August 2024

Background

Alzheimer’s disease (AD) is the leading cause of dementia. Genetic components play an important role in AD and have been widely evaluated by genome-wide association studies (GWAS) and exome sequencing, and some common and rare genetic variants have been identified. In addition to genetic factors, environment factors have a role in AD. Growing evidence from observational studies linked impaired kidney function to cognitive impairment and AD; however, there are inconsistences in these findings.

Objective

To determine the causal effects of impaired kidney function and chronic kidney disease (CKD) on AD.

Methods

Mendelian randomization (MR) methods have been widely used to infer causal associations between exposure and outcome. Here, we conducted an MR study to investigate the causal effects of impaired kidney function and CKD on the risk of AD by analyzing large-scale GWAS datasets from FinnGen and CKD Genetics (CKDGen) Consortium.

Results

We found no significant but a suggestive effect of CKD on decreased risk of AD using inverse-variance weighted (IVW) ( p = 8.46E–02) and simple mode ( p = 7.60E–02) methods. We identified a statistically significant effect of the estimated glomerular filtration rate (eGFR) on increased risk of AD using IVW ( p = 1.11E–02), weighted median regression ( p = 5.60E–03), and weighted mode ( p = 2.45E–02) methods.

Conclusions

Together, our findings indicate that high eGFR levels may increase the risk of AD. These findings need to be verified in future studies.

Published: August 2024

BACKGROUND: The postsecondary vocational outcomes of students with mental health disabilities (MHD) are poor and vocational rehabilitation factors contributing to better outcomes have not been identified. OBJECTIVE: Characterize demographic, service use and service outcome differences between youth with MHD and youth with other disabilities from state vocational rehabilitation agencies (SVRA) and identify factors predicting service use and service outcomes within youth with MHD. METHODS: Data were from 2015–2017 Rehabilitation Services Administration-911 case closure files. The sample consisted of 14–24-year-old SVRA applicants. Cross-disability characteristics, service use and outcomes were compared. Within youth with MHD, multivariate analyses examined factors contributing to having an Individual Plan for Employment (IPE) and successful case closure (i.e., with employment). RESULTS: Youth with MHD were underrepresented, older at application and were less likely to have IPEs and successful closures than youth in other disability groups. Within youth with MHD, application age and SVRA characteristics were the strongest predictors of having an IPE. Education and employment status at application strongly predicted successful closure. CONCLUSION: Youth with MHD, as in previous cohorts, continue to have lower service use and successful SVRA outcomes. Efforts are needed to increase their connection to SVRAs at younger ages. Youth with MHD without employment at application may need additional supports to achieve successful closures. Addressing several SVRA performance characteristics may improve their service use and outcomes.

BACKGROUND: The impact of different stroke types on specific activities of daily living (ADL) is unclear. OBJECTIVE: To investigate how differences between intracerebral hemorrhage (ICH) and cerebral infarction (CI) affect improvement of ADL in patients with stroke within a hospital by focusing on the sub-items of the Functional Independence Measure (FIM). METHODS: Patients with first-stroke hemiplegia (n = 212) were divided into two groups: ICH (86 patients) and CI (126 patients). Primary assessments included 13 motor and 5 cognitive sub-items of the FIM assessed at admission and discharge. Between-group comparisons and multiple regression analyses were performed. RESULTS: Upon admission, the ICH group exhibited significantly lower FIM scores than those of the CI group across various activities, including grooming, dressing (upper body and lower body), toileting, bed/chair transfer, toilet transfer, walking/wheelchair, and stairs. Age and FIM motor scores at admission influenced both groups’ total FIM motor scores at discharge, whereas the duration from onset affected only the CI group. CONCLUSION: Several individual FIM motor items were more adversely affected by ICH than by CI. Factors related to ADL at discharge may differ depending on stroke type. Recognizing these differences is vital for efficient rehabilitation practices and outcome prediction.
Are triage tools effective for detecting cervical spine injury in paediatric trauma patients? – A Cochrane Review summary with commentary
Authors: Capan Nalan
Published: August 2024

BACKGROUND: Pediatric cervical spine injuries (CSIs) from blunt trauma carry a high risk of neurological damage. Accurate diagnosis is vital for preventing harm and aiding recovery, yet the diagnostic accuracy of clinical decision rules (CDRs) remains unclear. OBJECTIVE: To assess the effectiveness of triage tools for detecting CSI in pediatric trauma patients. METHODS: A summary of the Cochrane Review by Tavender et al. (2024), with comments from a rehabilitation perspective. RESULTS: Five studies with 21,379 participants assessed seven CDRs. Direct comparisons showed high sensitivity but low specificity across different CDRs. Indirect comparison studies also demonstrated varying sensitivities and specificities. CONCLUSIONS: Insufficient evidence exists to determine the best tools for deciding if imaging is necessary for diagnosing potential CSI in children. Better quality studies are needed to assess the accuracy of CDRs for cervical spine clearance in this population.
The In Vivo Erythrocyte Sedimentation Rate (ESR) Test: Pandemic Reemergence of Robin Fåhraeus's "Fibrin Coagula"?
Authors: Forsdyke Donald
Published: August 2024

In the pre-antibiotic era, infections were usually more frequent and serious than today. In those times, Fåhraeus reported an _in vivo_ simulation of the clinical erythrocyte sedimentation rate test that was normally carried out _in vitro_ with freshly drawn blood. This led him to propose an explanation for the finding of long white strips (“fibrin coagula”) within the blood vessels of those who had died from infections. The surge of serious infections in pandemic times has likely kindled a reemergence of the phenomenon.
The Moorings of the Intangible: Technology and Social Control
Authors: Quesada Aguilar Juan Sergio
Published: August 2024

Current technological developments lead us to think about the novelty of the social system in which we live. In this paper we address how current technology responds to a conception of order rooted in the liberalism of the late nineteenth and early twentieth centuries, and an updating of its conceptions of work, leisure and welfare that only results in greater productivity, social control and profit. The speed of change and the lack of acceptance of these changes by people and institutions, provides ample opportunity for control and business for companies and governments that act with impunity, in the case of dictatorships, and with slight restrictions in the case of Western democracies. The undeniable advantages of the use of technology have their counterpart in the blurring of all that has to do with liberties and classic liberal rights.

Published: August 2024

Abstract
Adzan is the sound of certain words that indicate that the time for the fadhu prayer has arrived, and iqomah indicates that the prayer is ready to be performed. As a form of worship that falls into the category of sunna, it is not appropriate to sound the iqomah and adhan carelessly. Therefore, it is necessary to carry out community service in the form of training activities that use the Asset Based Community Development (ABCD) approach. The results of the community service show that training in calling the adhan and iqomah is very beneficial in teaching and improving the sounding of the adhan and iqomah properly and correctly, and can broaden children's understanding of the theories underlying the adzan and iqomah.
Keywords: Training, Adzan, Iqomah.

Modelling of the processes inside the nozzle of resistojet and arcjet with molecular propellant
Authors: Nesterenko Serhii , Shuai Peng
Published: August 2024

The first sample of the resistojet, which together with the arcjet belongs to the class of electrothermal thrusters, was developed in 1929-33 by the Ukrainian designer Valentyn Hlushko. Electrothermal thrusters combine the gas-thermodynamic principle of acceleration in a profiled nozzle with the use of electrical energy to heat the propellant. In resistojets, energy is supplied to the gas by an ohmic heater. In arcjets, the source of energy is the arc discharge. The advantage of this type of thruster is the greater value of the specific impulse compared to chemical rocket engines with solid or liquid propellants. In view of the inverse proportionality of the specific impulse to the square root of the molecular weight, hydrogen was initially chosen as the propellant. However, the operation of electric propulsion thrusters involves long-term propellant storage and excludes the use of hydrogen in liquid form. When stored in a gaseous state, due to the significant rarefaction of hydrogen, the mass of the balloon significantly exceeds the mass of hydrogen itself, negating the gain in propellant mass reduction compared to chemical engines. Interest in the development of electrothermal thrusters was revived by the proposal to use molecular propellants: ammonia and hydrazine. A mathematical model and a method for calculating thermochemical processes in the primary dissociation and secondary synthesis reactions of molecular nitrogen and hydrogen in the nozzle of an electrothermal thruster were developed in this work. The calculation method involves the use of continuity, momentum, and energy equations, considering the change in the molecular composition as the gas expands in the nozzle. The problem of lack of equilibrium constants was solved by generalizing the Saha ionization formula to the case of the interaction between nitrogen and hydrogen atoms. The calculation results demonstrate the possibility of obtaining a specific impulse at the level achieved when working on hydrogen. The necessity of using the non-stationary form of the equations during the creation of the process model in the heater or thruster arc is also indicated.

DISTRIBUSI INTESITAS TURBULEN PADA BELOKAN SALURAN DENGAN DASAR TERGERUS
Authors: Sumiadi Sumiadi
Published: August 2024

The flow characteristics on the channel bend are very complex. The Centrifugal force causes an increase in secondary flow. Increased secondary flow triggers changes in the channel bed topography. This phenomenon is very possible to change the flow structure including turbulent intensity. This research aims to determine the distribution of turbulent intensity at eroded-bed channel bend and to compare whether the equations of the turbulent intensity distribution by Nezu (1977) are still valid. This research was conducted at the Hydraulic Laboratory using 180° curved open channels. The bed material is sand with a median diameter, 1 mm and a density of 2.67 gr/cm3. The flow in the approach section is uniform flow and changes to non-uniform flow in channel bend. Measurements were carried out on equilibrium conditions of bed material. 3D instantaneous velocity measurements are carried out at 8 cross sections using Acoustic Doppler Velocimeter (ADV). The results showed that due to the presence of secondary flow in the channel bend caused a change in turbulent intensity distribution. In general, the horizontal turbulent intensity is greater than the vertical turbulent intensity. While the turbulent intensity in the outer bank tends to be greater than the inner bank. Furthermore, the vertical distribution of turbulent intensity in the eroded channel bend does not follow the exponential equation proposed by Nezu (1977).Karakteristik aliran di saluran menikung sangat kompleks. Gaya sentrifugal menyebabkan peningkatan aliran sekunder. Peningkatan aliran sekunder memicu perubahan topografi dasar saluran. Fenomena ini sangat berpotensi mengubah struktur aliran termasuk intensitas turbulen. Penelitian ini bertujuan untuk mengetahui distribusi intensitas turbulen pada belokan saluran dengan dasar tergerus dan membandingkan apakah persamaan distribusi intensitas turbulen oleh Nezu (1977) masih berlaku. Penelitian ini dilakukan di Laboratorium Hidrolika menggunakan flume dengan sudut belokan 1800. Material dasar yang digunakan adalah pasir dengan diameter median 1 mm dan rapat massa 2.67 gr/cm3.Kondisi aliran pada saluran pengarah di upstream adalah seragam dan berubah menjadi aliran tidak seragam pada bagian belokan. Pengukuran dilakukan pada kondisi material dasar equilibrium. Pengukuran kecepatan sesaat 3D dilakukan pada 8 cross section menggunakan Acoustic Doppler Velocimeter (ADV). Hasil penelitian menunjukkan akibat adanya aliran sekunder pada belokan saluran menyebabkan terjadinya perubahan distribusi intensitas turbulen. Secara umum, intensitas turbulen horizontal lebih besar dibandingkan dengan intensitas turbulen vertikal. Sedangkan intensitas turbulen di sisi luar belokan cenderung lebih besar dari sisi dalam belokan. Selanjutnya, distribusi vertikal intensitas turbulen pada belokan saluran dengan dasar tergerus tidak mengikuti persamaan eksponensial yang diusulkan oleh Nezu (1977).

Authors: Rumahorbo Evryanti Elisabeth , Sembiring Sri Gunana
Published: August 2024

The author's project of choice is an educational and leisure center housed in the former Deli Tobacco Hospital. Deli Tobacco General Hospital on Putri Hijau Street, Medan, North Sumatra. is a hospital that was founded in 1908 with the name Veregnide Deli Maatschapy Hospital. This hospital was founded to anticipate the high death rate of plantation workers at that time. The plantation workers are said to be attacked by diseases that are often found in tropical areas, such as beriberi and malaria. And now this building has been closed by PT Perkebunan Nusantara II since January 2012. Co-working spaces, libraries, museums, workshop areas, shops, restaurants, and cafés are all included in the design area's scope. Worship spaces, parks, and playground areas are included as supporting services. The author used tropical architecture in both indoor and outdoor areas when creating this project to address the issues that arose. In and of itself, tropical architecture considers the local climate. It is envisaged that by applying the idea of Tropical Architecture to the project, the author will be able to create architectural solutions that will make users of the Edu-recreational Center more comfortable. The way the area between the internal and outdoor spaces is arranged and laid out subsequently demonstrates how this tropical architecture is being applied.

Medan State Polytechnic (Polmed) Polmed plans to become a green campus by 2025. This research examines Polmed's readiness in accordance with the UI GreenMetric indicators in the transportation category, by collecting primary and secondary data which is analyzed using qualitative and quantitative methods. With a land area of ± 84,420.74 m² and a total campus population of 6,748 people with a distribution of Polmed personnel and academic data, the total number of students is 6,270 people and the number of lecturers, educational staff and administrative staff is 478 people in 2022/2023, producing results research based on the UI GrreenMetric indicator that there is still low availability of environmentally friendly transportation systems in the Polmed campus area, namely the absence of an emission-free vehicle policy and the absence of initiatives to reduce private vehicles in the Polmed campus area. The program to limit or reduce parking areas on campus over the last 3 years has resulted in a reduction in parking areas of 10 - 30%. Even though pedestrian paths are available, only a few areas are said to be safe and comfortable, but are not yet friendly for people with disabilities. From the overall indicator, the score obtained was 725 out of 1,800 or 40.28% in the transportation category. To increase the percentage, efforts can be made to implement the use of electric vehicles, redesign pedestrian paths that are safe, comfortable and accessible for people with disabilities and redesign parking lots by creating multi-level parking

Pengetahuan siswa terkait bagaimana menjaga gigi dan gusi merupakan faktor penting dalam kesehatan anak khususnya pada usia 6 sd 12 tahun, hal ini karena peran orang tuan juga sangat berpengaruh terhadap proses pendidikan anak sejak dini. Orang tua, perlu membiasakan anaknya untuk menjaga kebersihan mulut dengan menggosok gigi secara teratur. Kebersihan dan kesehatan gigi sulung seringkali kurang mendapatkan perhatian dari orang tua, hal ini karena anggapan bahwa kerusakan pada gigi sulung bukan merupakan suatu masalah dan tidak memerlukan perawatan karena akan digantikan oleh gigi permanen. Oleh karena itu Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan edukasi bagaimana cara merawat gisi dan gusi yang baik untuk para siswa-siswa di asdn pulorejo Tembeanga Jombang mengenai kesehatan gigi dan mulut balita. Sebelum kegiatan ini dilaksanakan, dilakukan pembuatan buku panduan yang berisi materi mengenai tumbuh kembang gigi pada anak, ciri gigi sehat, diet sehat serta cara pemeliharaan kesehatan gigi dan mulut balita yang bekerjasama dengan petugas puskesmas tembelang. Metode yang dilakukan adalah melakukan penyuluhan dan edukasi mengenai kesehatan gigi dan mulut balita, pelatihan keterampilan menyikat gigi, bagi siswa kelas 4, 5 dan 6 SDN pulorejo tembelang jombang. Sebelum dilakukan penyuluhan dan edukasi, dilakukan pre testter lebih dahulu untuk menilai pengetahuan awal para siswa mengenai kriteria gigi sehat, cara pemeliharaan kebersihan rongga mulut siswa, serta edkasi makan-makanaan sehat. Setelah diberikan penyuluhan dan pelatihan dilakukan post test dengan soal yang sama. Hasil dari kegiatan ini ialah adanya adanya peningkatan pengetahuan pada 100% peserta dari target 70%, serta 70% peserta lulus uji keterampilan tentang cara menyikat gigi pada siswa yang terpilih. Diharapkan dengan meningkatnya pengetahuan dan keterampilan siswa-siswa di SDN pulorejo dapat diaplikasikan dalam kehidupan sehari-hari sehingga dapat meningkatkan kesehatan gigi dan mulut siswa di SDN pulorejo tembelang jombang.Sebagai kelanjutan dari kegiatan pengabdian masyarakat ini diharapkan dapat dilakukan evaluasi kembali mengenai tingkat pengetahuan dan keterampilan siswa-siswa nantinya, serta dapat dilakukan pembuatan buku dan video edukasi yang berisi cara- cara pemeliharaan kesehatan gigi dan mulut pada siswa-siswiSDN pulorejo tembelang jombang.

Education is a process of maturing the quality of life. Humans carry out education in order to improve and increase their standard of living. Basic mathematics is a branch of mathematics which is often referred to as arithmetic, which studies the arithmetic operations of addition, subtraction, multiplication and division. Based on the results of a survey by conducting interviews with several class II and III students, many class II and III students at SDN Betek I did not master basic multiplication calculations, had difficulty calculating quickly and lacked interest in counting because the learning media was too monotonous and lacked variety. The aim of training in using multiplication smart board learning media is to increase students' interest in counting and provide media that is more fun and interesting for students so that students do not get bored easily when learning to count. Implementation of community service activities uses the Participatory Action Research (PAR) method. Action and participatory methods are implemented in mentoring activities to introduce learning media created by the community service team. The result of this community service activity is that students' abilities have increased after being given training in using learning media in the form of multiplication boards and students are finding it easier to solve problems related to basic arithmetic material, especially multiplication, students are also more likely to solve basic arithmetic story problems in everyday life.

Learning cannot be separated from learning media which functions to facilitate students' learning activities. Training on making learning media. Flat buildings become key chains in the context of P5 (Pancasila Student Profile Strengthening Project) Merdeka Belajar is an innovative way to integrate education with ecopreneurship principles. This training aims to enable MI Asy-Syafiiyah students to memorize flat shapes through ecopreneurship-based learning media, and so that MI Asy-Syafiiyah students can have an entrepreneurial spirit from an early age. The approach method for implementing community service activities includes demonstration and workshop (training) methods. For data collection methods, interviews were used with class teachers and school principals. This training was attended by 30 MI Asy-Syafiiyah students. The results of the training socialization which was carried out in 3 stages, namely the planning stage, implementation stage and evaluation stage, received a good response from the students and teachers of MI Asy-Syafiiyah, marked by an increase in students' understanding of spatial construction and the spirit of ecopreneurship being embedded in the students.

ABSTRACT
Early Childhood Education (PAUD) is a level of education carried out before the basic education level which is an effort to develop children aged 0-6 years. Early childhood education is a form of education that focuses on laying the foundation for growth and development. Based on the results of analysis and observations, the Community Service team from KH University. A. Wahab Hasbullah holds seminars or training on making alphabet calendars to help teachers provide an overview of innovative learning methods. The results obtained from reading skills training using the Alphabet Calendar showed that partners' knowledge about recognizing alphabet letters and making learning media increased after the training. This training indirectly has an impact on the Economic, Social, Health and Education sectors. If this alphabetic calendar is made widely in educational institutions, this training will indirectly improve students' reading skills and reduce environmental pollution caused by waste such as used cardboard.
Keywords: Training, Innovation, Alphabetical Calendar, PAUD.
A Numerical Investigation Into the Natural Frequency Analysis of Delaminated 3D-Printed PLA Beams Including Contact
Authors: Tabe Yousef
Published: August 2024

This report includes the results of experimental and numerical modal analyses, performed to determine the flexural fundamental natural frequency of the 3D-printed PLA beam with delamination. Two types of 3D-printed samples, having 0.1mm and 0.5mm delamination thicknesses, are studied. The results of numerical modal analysis are compared and verified against those obtained experimentally. The Finite Element Analysis (FEA), carried out numerically using ABAQUS software, was performed for six cases. For a sample with 0.1mm delamination thickness, two analyses were performed by first excluding and then in the presence of contact/friction in the delamination zone. Another specimen, with a 0.5mm-thick delamination region, was also investigated, where two sets of studies were conducted. The delamination region was first modeled as uniform and was then refined to include the geometric non-uniformity resulting from the 3D-printing process. The latter model exhibits a more realistic representation of the real sample. In each case, two numerical modal analyses were performed, without and with friction contact in the delaminated segment. At the end, a comparison is made between all these models to show the effect of friction, delamination thickness, as well as uniform vs realistic modeling of the delamination, on the bending fundamental frequency of the PLA delaminated beam.
Liminal Ecologies: A Lexicon and Preliminary Inventory of Liminal Ecologies in the City of Toronto
Authors: Cooke Aylise
Published: August 2024

The existence of liminal ecologies provides an opportunity to reintegrate nature into urban spaces and urban life. Supporting biodiversity and the human nature connection in cities is necessary to mitigate the harms of Global Climate Change. A connection to nature has been linked to environmentally protective behavior and identified as a strategy to grow a more resilient future. Westernized valuation systems of conceptualizing and protecting biodiversity have isolated people from nature. This disconnection from nature disproportionately impacts equity seeking communities in cities. Considering the geographic and policy landscape of the City of Toronto, this paper will demonstrate the opportunity for liminal ecologies to increase equitable access to nature, foster the human nature connection and support urban biodiversity. A lexicon and preliminary inventory will be proposed to facilitate understanding of liminal ecologies and their potential towards reimagining the city. This work will set the foundation for further investigation of liminal ecologies as a catalyst for cultivating our collective relationship to nature in the City of Toronto.
A Design-Oriented Framework for Interactive Digital Narrative (IDN) in Virtual Reality (Focus on Branching Narrative and Agency)
Authors: Soltani Samira
Published: August 2024

Finding a design-oriented framework for interactive digital narrative (IDN) in virtual reality (VR) focusing on branching narrative and agency is the main goal of this research. Incorporating a practice-based research methodology, this study analyzed three virtual reality projects focusing on agency and three products from different media (print, movie, VR experience) focusing on branching narratives. The extracted framework comprises six sections: the interactor, actions, decisions, feedback and acknowledgment, VR features, and Accessibility. This design-oriented framework is applied to a narrative with a fundamental choices branch at the first scene, which makes the interactor's experience different. As explained in the design-oriented framework, all of the branches in this narrative are not determinative for the storylines, and sometimes they just play a vital role in the branching experiences.
