Authors: Hariom  , Sharma Kailash Chandra , Singh Krapal , Singh Dharamender 
Published: April 2024

Objective: The objective of this study is to investigate the continuous-production inventory problem for a single product at a three-level facing a constant deterioration rate. It is anticipated that the customer will make renewal arrangements in accordance with the established and extensively utilized order-up-to policy, and may place orders from two providers with differing prices and levels of consistency.

Theoretical Framework: In this study demand is a linear function of time, and the deterioration rate is persistent. In this model, the shortage is allowed, and partial backlogging. It is expected that the backlog rate is influenced by how long it takes to get the next replenishment. It involves aspects from various areas of scientific knowledge to understand the different perceptions contained in the scientific literature on the phenomenon of Industry 4.0.

Method: The algorithms for this model have been developed in Mathematica Software 9.0. We examine the effects of several difficulty criteria on the best options regarding manufacturing time and replenishment at the store using analytical analysis.

Results and Discussion: Thus, our model offers a novel management insight that aids in achieving the ideal profit level for a production system or business. In reality, we obtain a promising outcome from the numerical case. To compare various solutions, we also carry out very comprehensive numerical experiments.

Research Implications: This research aims to detect the best course of action for reducing overall inventory costs and increasing overall income. We also verified that the total cost and commonly optimal time used to interrupt geometric production systems could be analyzed with a constant production model. This approach is particularly relevant for organizations seeking to improve operational efficiency and customer satisfaction through better risk management.

Originality/Value: This study contributes to our understanding of how and with whom to collaborate by highlighting the relationships among inventory management, innovation performance, and logistics performance. The value of the study is the contribution it makes to the literature on the cost analysis issues. Therefore, the article can be of benefit to the scientific community with an interest in the study of the subject.

Authors: Afifi Mohammad Salva , Dahda Said Salim 
Published: April 2024

. PT XYZ is a palm oil derivative processing company that produces biodiesel / FAME (Fatty Acid Methyl Ester) products. However, there are several obstacles that still occur during the company's production process which causes the acid value (AV) level of FAME products to not meet specifications and there are 3% defective products. Therefore, this study aims to determine the improvement plan by applying kaizen to the Six Sigma improvement stage and reducing outspec products in the FAME production process. The results of the research conducted using the six sigma method show that the company has a DPMO value of 71,459 and a sigma value of 2.96 which is in the average position of the industry in Indonesia based on the results of data processing. While recommendations for improvement by implementing kaizen include training machine operators, making standard operating procedures (SOPs) for machine inspections on each shift, reducing the amount of strearin added to AV raw materials before pre-treatment, maintenance and machine calibration. This step are expected to overcome the main problems identified in the study.

Inverse Domination in X-Trees and Sibling Trees
Authors: Shalini V. , Rajasingh Indra 
Published: April 2024

A set $D$ of vertices in a graph $G$ is a dominating set if every vertex not in $D$ is adjacent to at least one vertex in $D$. The minimum cardinality of a dominating set in $G$ is called the domination number and is denoted by $\gamma(G)$. Let $D$ be a minimum dominating set of $G$. If $V-D$ contains a dominating set say $D^{'}$ of $G$, then $D^{'}$ is called an inverse dominating set with respect to $D$. The inverse domination number $\gamma^{'}(G)$ is the cardinality of a minimum inverse dominating set of $G$. A dominating set $D$ is called a connected dominating set or an independent dominating set of $G$ according as the induced subgraph $\langle D \rangle$ is connected or independent in $G$. The minimum of the cardinalities of the connected dominating sets of $G$ or the independent dominating sets of $G$ is called the connected domination number $\gamma_{c} (G)$ or the independent domination number $\gamma_{i} (G)$ respectively. In this paper, we determine the inverse domination numbers in X-Trees and Sibling Trees. We have also determined the independent domination numbers of both the trees and the connected domination number of Sibling Trees. A result on inverse domination number of some classes of Hypertrees is also included.

The fundamental problem in this research is to explore a more profound understanding regarding both performance and efficiency in quantity computing. Successful implementation of algorithms in computational computing environments can unlock the potential for significant improvements in information processing and neural network modelling. This research focuses on developing the Madaline and Perceptron algorithm using a quantum approach. This study compares the two algorithms regarding the accuracy and epoch of the test results. The dataset used in this study is using a lens dataset. There are four attributes: 1) patient age: young, pre-presbyopia, presbyopia 2) eyeglass prescription: myopia, hypermetropia 3) astigmatic: no, yes. 4) tear production rate: reduced, normal. There are three classes: 1) patients must have hard contact lenses installed, 2) patients must have soft contact lenses installed, and 3) patients cannot have contact lenses installed. The number of data is 24 data. The result of this research is the development of the Madaline and Perceptron algorithms with a quantum computing approach. Comparing these algorithms shows the best accuracy is the Perceptron algorithm, namely 100%. In comparison, Madaline is 62.5%, and the smallest epoch is the Madaline algorithm, namely 4 epochs, while the smallest Perceptron epoch is 317. This research significantly contributes to developing computing and neural networks, with potential applications extending from data processing to more accurate modelling in artificial intelligence, data analysis and understanding complex patterns.

Hop-on Hop-off Spirituality
Authors: Hiiemäe Reet 
Published: April 2024

In contemporary spirituality-related thought and behaviour in Estonia (as well as in a number of other regions), a phenomenon can be observed that I call hop-on hop-off spirituality. This means testing and tasting of various forms of contemporary spirituality (via techniques, courses, lectures, books, etc.) out of curiosity or for fun or just because a friend said that this or that teaching has changed their life. Such experimenting can sometimes result in deeper spiritual involvement or change in worldview but often doesn’t bring along anything that could be defined as deeper spiritual or religious commitment or belonging. Based on interviews, questionnaire responses and written life-history narratives from Estonia from the 1990s to 2020s, I will analyse how the suggested term fits into the context of already existing definitions and terms related to “spirituality”, and how such “hop-on hop-off” participation can be still seen as a learning process that influences one’s values, meaning-making, coping models, and lifestyle.

Mango golek is one of the superior varieties in Indonesia. Utilization of local varieties of mango peel in a fresh form as raw material for functional drinks is not yet available. This study aims to develop ripe mango peel into a ready-to-drink functional beverage product with the addition of red ginger extract and rambutan honey which aims to improve the functional and sensory properties of mango peel extract as an effort to diversify food. The experimental design used a one factor Completely Randomized Design (CRD) with three treatment levels (mango peel extract: red ginger extract: rambutan honey) namely A0 (100%: 0%: 0%), A1 (85%: 10%:5%), and A2 (75%:15%:10%). The analysis included organoleptic tests (sensory and hedonic quality), physical tests (total dissolved solids and pH), and chemical tests (antioxidant activity and total phenol). The decreased levels of mango golek peel extract as well as increase of red ginger and rambutan honey gave a tendency to increased the value of sensory, hedonic quality, total soluble solids, antioxidant activity and total phenol but gave a tendency to decrease the pH value of functional drinks. Selected product of functional drinks based on mango golek peel extract was A2 had a sensory quality of orange color (6.84), uncharacteristic aroma of mango peel (5.50), uncharacteristic taste of mango peel (5.48), non-bitter aftertaste (6.93), turbid appearance (3.35) and uncharacteristic overall of mango peel (5.83) and had a very high level of hedonic preference with a score of 6.18-6.99. The selected formula had a total dissolved solids value of 10.6°Brix; pH 4.83; antioxidant activity 51.07% and total phenol 0.48 mg GAE/g.

Seaweed is the primary source of carrageenan, but it also contains iodine, which can inhibit bacterial activity and growth. The iodine contained in seaweed results from interaction with the marine environment rich in iodine. The research was conducted from June to November 2022 and used iodine from seaweed extraction to test antibacterial activity (Staphylococcus aureus and Salmonella sp). The antibacterial activity test was carried out for 48 hours. The iodine concentration was determined using titration, while the antibacterial activity test used the Disc Diffusion Test. The research showed that Eucheuma spinosum extract contained iodine, 0.38% - 1.22%. The antibacterial activity of seaweed iodine test results revealed an average inhibition zone diameter of 11.5 mm for Staphylococcus aureus and 12 mm for Salmonella sp. This research shows that the iodine in Eucheuma spinosum extract has an inhibitory solid impact on the activity and growth of Staphylococcus aureus and Salmonella sp.

Published: April 2024

The surging popularity of cryptocurrencies presents both opportunities and challenges. While some view it as the future of finance, others remain concerned about investment risks. This uncertainty creates difficulties for consumers and financial institutions. To address this gap, the study assessed consumer perceptions of cryptocurrency investment risks and perceived usefulness, aiming to identify new avenues for transactions and investments. Employing a quantitative descriptive approach, a survey was conducted among 150 individuals from two (2) cities in the Philippines using a validated instrument and the Technological Acceptance Model (TAM). Results showed that consumers perceived moderate risk across trust, privacy, security, and financial aspects. No significant demographic variations were found in risk perception or perceived usefulness. These findings suggest a generally positive consumer attitude toward cryptocurrency investment despite the risks. This implies the possibility of widespread adoption if expectations align with the technology’s actual capabilities. Ultimately, this study offers valuable insights into consumer decision-making, which can inform future risk management strategies in the cryptocurrency landscape. It focuses on a geographically under-researched population (Philippines). This research contributes valuable insights for policymakers and industry leaders developing strategies to promote responsible cryptocurrency adoption across diverse user groups, particularly in emerging markets.

A thorough theoretical and practical preparation is crucial in the education of medical professionals. Present-day knowledge recipients expect a broad range of multimedia and interactive resources in the consumed media. The article discusses examples of such implementations for the nationwide education of a pharmacy technician, massage technician, medical sterilization technician, and occupational therapy technician. These examples were created for the Integrated Education Platform of the Ministry of Education and Science in Poland, as part of an EU-funded project. This study delineates the characteristics of e-materials, such as instructional and educational videos, film sequences, scenario-based learning games, interactive documentation, 3D animations, simulators and virtual tours. We prepared a learner benefit analysis based on the e-materials discussed. We aimed to formulate recommendations and guidelines for designing and developing multimedia and interactive resources, paying special attention to educational values and content for the medical industry. Regardless of the type of multimedia, profession and content, materials should prioritize realism, interactivity and detailed presentation of the situations/cases. The same multimedia rarely achieve different learning objectives and learning outcomes. To design and produce high-quality multimedia, it is necessary to know their characteristics and to work with a team of subject matter experts experienced in e-learning development.

LAY SUMMARY Families offer vital mental health and well-being support to Veterans and public safety personnel. This study offers a model of how families can experience moral distress from service cultures that exclude them, leaving families stuck, exacerbating a sense of moral distress resulting from perceived organizational betrayal felt in the context of families’ help-seeking experiences. The model was informed by in-depth interviews conducted in Australia with 25 family members with experience seeking help and providing support to a family member who is a Veteran or public safety personnel. The interviews provided a detailed description of how embedded and aligned families were to a member’s service role, and their profound sense of betrayal and distress when attempts to support family members’ mental health were thwarted. Families may experience moral distress from identifying the problem and potential support solutions, but having nowhere to go to realize those supports for their family member. The implications for Veteran and public safety organizations as well as health professionals to promote more meaningful involvement of families is discussed.

Published: April 2024

LAY SUMMARY Some family care-partners of Australian Veterans have high levels of distress and feel there is little consideration or acknowledgement of the role they play in supporting Veterans in their day-to-day lives. They also feel limited support is available as a family carer. Family care-partners rarely prioritize their own well-being, leaving them at risk of poor health outcomes. This study extended previous work in South Australia to attempt to understand the physical and mental health status of family care-partners across the country. It sought to identify care-partners’ emotional and practical support needs, determine whether access to supports was available, and discuss the broader impact of the caring role. While fewer care-partners participated than anticipated, the findings suggest that the psychological well-being of family care-partners is impacted by their caring role, and there is a need for accessible supports that are culturally safe, non-judgmental, and promote wellness and early mental health intervention for the care-partner, Veteran, and entire family unit.
