Authors: Malsaria Anshika , Vyas Pankaj , Kaur Manjit
Published: April 2024

The resilient and secure image encryption method presented in this research combines the benefits of Lorenz maps and double random phase encoding (DRPE) with compressed sensing. The suggested method attempts to maximize the use of storage resources while maintaining the security and integrity of sensitive image data during transmission and storage. Utilizing the energy compaction characteristics of the original image, compressed sensing with discrete cosine transform (DCT) is used in the encryption process to effectively represent and transmit the encrypted data. Lorenz maps are also used to create double random phase masks, adding high unpredictability and key sensitivity to strengthen the encryption scheme’s security. Utilizing a variety of performance indicators, including the PSNR, NPCR, MSE, and SSIM, experimental investigations demonstrate the usefulness of the suggested strategy.

Published: April 2024

Internet of Things (IoT) technology has revolutionized patient monitoring systems by providing real-time health data for better medical care. However, the rise of IoT devices raises privacy concerns about sensitive health data. This study uses Attribute-based Cryptography (ABC) in patient monitoring to address these concerns. The focus is on adapting attribute detail to IoT device features. Conventional encryption methods often struggle to adapt to IoT devices limited resources, which could compromise patient data privacy. This study suggests a tweak to ABC by adjusting the attribute granularity to better fit the limitations of IoT devices. These resource constraints present challenges, but the methodology proposes an innovative approach to handling and analyzing attributes while protecting patient confidentiality. A dynamic attribute granularity(DAG) model that adapts to IoT device capabilities ensures a data privacy-system performance trade-off in the study. The suggested approach optimizes attribute number and complexity to improve privacy-preserving patient monitoring system scalability and performance. The research thoroughly evaluates the modified ABC-DAG systems data privacy, scalability, and energy efficiency. The results show that the system can protect patient data in a healthcare IoT setting while reducing computational load on low-resource devices. The growing field of privacy-preserving healthcare Internet of Things benefits from this research. It addresses IoT attribute granularity challenges with a customized cryptographic method. The results improve ABC theory in healthcare and provide practical advice for secure and efficient IoT patient monitoring systems.
Digital Boundaries: A Review of Clinical and Ethical Issues in Telepsychology among Mental Health Professionals
Authors: Manalili Jeric
Published: April 2024

With the COVID-19 epidemic starting in early 2020, the unintentional mass migration to online therapy has drastically changed the landscape. Because of this, mental health professionals need to be conscious of the fact that their traditional ethical obligations still hold even while using technology to offer a service. This scoping study examined the applicability of telepsychology among mental health practitioners as well as its ethical and clinical concerns. There is general agreement in this study that providing mental health treatments to clients via telepsychology is a realistic and practical option both before and after the epidemic. There was a clear pattern that the most prevalent clinical concerns were restricted nonverbal communication between the therapist and the client, communication difficulties in the therapeutic relationship, unsuitable to some mental health disorders, and clinician exhaustion. On the other side, privacy, and secrecy, insufficient telepsychology training and instruction, boundary-related concerns, insufficient telepsychology rules, and handling emergencies were significant ethical issues. These findings open the door to telepsychology, a workable method of providing mental health and psychosocial treatments that aim to reach clients across geographic boundaries and continue the transformative job of fostering change, healing, and growth among clients. Understanding these problems makes it easier for mental health practitioners to respond to future public health emergencies and other natural catastrophes
An Electrical Power Inventory and Monitoring System
Authors: Bravo Corleto
Published: April 2024

The Inventory Management and Monitoring System is a software that is helpful for the various business sectors that operate in stores, products, and services where storeowners, products and services proprietors keep the records of sales and purchases, supply and demand, and risk and opportunities. A mismanaged inventory means disappointed customers, too much cash tied up in warehouses, slower sales, and sometimes detrimental to the work relation environment, investments and businesses, and most probably financial losses. Inventory control problems often result in record and physical count discrepancies which may ultimately lead to higher than preferred inventory levels. Conversely, accurate inventory records result in lower inventory investment and are the foundation for forecasting, ordering, tracking, vendor evaluation, dead stock, and administration plans and decisions.
 
The researcher observed that most of the application of the inventory system was sales and products. Through this study, the researcher applied inventory in terms of electrical maintenance relations which includes electrical supplies, devices and equipment, services, and electrical power consumption. An Agile software development methodology was used in developing the system. The inventory archive maintenance system was developed using Java, HTML, CSS, PHP, PhpMyAdmin, and MySQL. The Inventory System includes Messaging, Supplies Inventory, Job Orders, Repair Records, and Wattage Consumption. Integration of disciplines made the study finished and the user’s manual was produced for guides and references for the use of the system.

In the Philippines, different sizes and types of pump sets are utilized for shallow tubewells (STW) and low-lift pumps (LLP). Filipino farmers used STW and LLP as main or supplementary sources of irrigation. This study aimed to evaluate the performance of agricultural pumps and pump sets tested by the Agricultural Machinery Testing and Evaluation Center (AMTEC) from 1989 to 2022, based on Philippine Agricultural Engineering Standards (PAES) 115:2000. A total of 486 centrifugal pump sets and 341 bare pumps were used in the study. The selected sizes for both bare pump and pump set (engine-powered) include 50x50mm, 75x75mm, and 100x100mm. These were the common sizes and prime mover used for STWs and LLPs in the Philippines. The performance of the agricultural pumps was evaluated with equal weights using the: a) discharge-to-input power ratio, b) suction lift, c) maximum efficiency, and d) input speed. For all bare pump sizes, non-self-priming (52.99%, 61.05%, 62.21%, respectively) and discharge capacity (7.78lps, 15.78lps, 25.54lps, respectively) have higher pump efficiency than self-priming. All sizes of non-self-priming pumps are driven by diesel engines. Results showed that, generally, for pump sets system efficiency, in general: a) it is relatively higher for non-self-priming than self-priming (same with bare pump efficiency); b) relatively higher for diesel than gasoline engine driven; and c) relatively higher for water-cooled than air-cooled diesel engine. This study has also found that most of the evaluated bare pumps met the criteria of the performance evaluation scheme, including all of the 100x100mm non-self-priming units. On the other hand, most of the 100x100mm self-priming, close-coupled (17/25); 75x75m m self-priming, close-coupled (79/100); 50x50mm selfpriming, V-belt drive (6/6); and 50x50mm self-priming, close-coupled (101/109) pump sets did not meet the criteria of the evaluation scheme. Appropriate tools (i.e. statistical) or systems should be utilized to determine the performance parameters and corresponding performance values for the evaluation of the pumps and pump sets.

Authors:   University of the Philippines Los Baños, Dasco Agerico Neal , Acabal Ma. Camille , Manuel Luther John , Pascual Mary Louise
Published: April 2024

Because of its nutritious qualities and growing demands, an attempt to support the Philippine Guapple industry was enacted through edible coating. Especially those of starch and chitosan formulation, edible coatings are known to develop low-cost and biocompatible resistance from the drastic changes that commodities experience from their surroundings. Thus, becoming a low-cost technology to prevent yield losses and decrease rate of senescence for selected fruits. With the control treatment as the designated Treatment 1, Treatment 2 Guapples are treated with coating concentrations of 2% Alginate + 0.5% Chitosan, and Treatment 3 Guapples are those that have been treated with 2% Alginate + 0.5% Chitosan + 2% Starch. This setup identifies if the variations of Starch and Chitosan concentrations affect the overall postharvest qualities of Guapples. The physico-chemical parameters were measured through non-destructive and destructive tests, as they relate to the overall process of senescence. Replicated four times in ambient conditions (28°C, ~80% RH ), the physico-chemical variables are recorded periodically in a span of one week. It was found that in moisture loss deterrence, the coating from Treatment 2 is the most effective, with significant moisture loss deterrence (vs. Control) found during Day 2. On the other hand, it was found that in preserving the Guapples from Browning, Treatment 3 does it slightly better. No other significant changes were found in terms of other chemical properties of Guapple such as Total Soluble Solids, Titratable Acidity, pH, Firmness, and Ripening Index. Furthermore, the consumer sensory evaluation suggests that they are unable to find any significant preferential difference, except for slight preferences in Visual Quality found in Guapples with Treatment 3. Moving forward, maintaining temperature in the laboratory is recommended as it is determined to be a confounding variable that may have affected results in a warm June climate.

Published: April 2024

Near-infrared spectroscopy (NIRS) coupled with multivariate statistical analysis was assessed as a rapid method of detecting honey adulteration in the Philippines. The sample set contained 288 spectra of authentic and adulterated honey samples obtained from six farms in the provinces of Benguet and La Union. Spectral data were pre-processed using ParLeS software in which partial least squares regression (PLSR) analysis was employed. Multivariate analyses like PLSR, principal component analysis (PCA) and linear discriminant analysis (LDA) were performed to predict the level of adulteration, reducing sugar content, and apparent sucrose content. Calibration models for predicting adulteration level (from none to highly adulterated) gave the best results using PLSR on spectral data without pretreatment (calibration R2 > 0.93, validation R2 > 0.94). Principal components (PCs) of the spectral data were extracted using PCA wherein the NIR absorbance bands for sugar (836-840 nm and 978-980 nm) and water (938-940 nm, 978-980 nm, 984-986 nm and 992-994 nm) in honey were identified. Using LDA, calibration models were able to classify honey based on level of adulteration and apparent sucrose; overall accuracies of 99.5% and 100% were observed, respectively. When validated, however, the LDA models could not detect pure honey (out of 6 and 11 samples, respectively), while 86.7% and 100% of adulterated honey could be detected, respectively. Further sampling is recommended to strengthen LDA models.

Published: April 2024

Social entrepreneurs play a crucial role in addressing entrenching societal problems that are difficult to solve at the individual level. To cultivate future social entrepreneurs, institutions increasingly provide experiential education programs where participants engage directly in social entrepreneurial activities. This study aims to identify psychological factors influencing the development of social entrepreneurial intentions among participants in such programs. Highlighting the challenging nature of a social entrepreneurial career, we propose that participants' learning goal orientation, meaning at work, and bottom-line mentality climate perception shape their intentions to become social entrepreneurs. We collected and analyzed two-wave survey data from 149 university students participating in an intensive experiential social entrepreneurship education program in South Korea. Results indicate that learning goal orientation positively affects meaning at work, which in turn, enhances social entrepreneurial intentions. Furthermore, bottom-line mentality climate perceptions moderate the positive relationship between learning goal orientation and meaning at work, as well as the positive effect of learning goal orientation on social entrepreneurial intentions via meaningful work. This study has several significant implications. First, it proposes and demonstrates that individual participants' learning goal orientation and meaning at work serve as predictors of the development of social entrepreneurial intentions during an experiential entrepreneurial education program. In doing so, it sheds light on the critical role of psychological variables in influencing the outcomes of entrepreneurial education. Second, the study reveals the negative effects of bottom-line mentality climate perception on shaping social entrepreneurial intentions, suggesting the necessity for educational frameworks that incorporate environmental contexts. Finally, this research offers evidence-based insights that educational institutions, policy-makers, and business leaders can utilize in devising strategies and systems to nurture the next generation of social entrepreneurs.

Authors:   The Korean Career·Entrepreneurship & Business Association, Ha Hojung , Koo Inhyouk
Published: April 2024

This study investigates the challenges hindering student entrepreneurs from commercializing their ventures despite having entrepreneurial intentions, and it explores the role of marketing capabilities in overcoming these obstacles. We observed 145 students at University A, which offers a semester-long intensive entrepreneurship course, across three instances to examine their entrepreneurial intentions, marketing competencies, and the journey to business startup post-course. The findings reveal that strong entrepreneurial intentions do not directly lead to business commercialization through business registration. Instead, there is a significant positive correlation between entrepreneurial intentions and marketing capabilities related to understanding markets and customers. Moreover, both general and specialized marketing competencies play a crucial mediating role in bridging entrepreneurial intentions and he actual commercialization of businesses. This research highlights the gap between the intention to start a business and actual startup activities among student entrepreneurs, underscoring the need for educational content and methodologies that bolster marketing skills in university entrepreneurship programs. The study suggests that while it is vital to enhance customer-oriented skills based on fundamental marketing principles, developing specialized abilities to analyze markets and competitors and leveraging these insights in the entrepreneurial process is equally important. The implications of this study point towards the integration of practice-oriented marketing projects and curricula that go beyond basic customer analysis, offering a comprehensive approach to entrepreneurship education.

Authors:   The Korean Career·Entrepreneurship & Business Association, Ji HeaSoon , Lee YoungMin
Published: April 2024

The study aimed to examine job characteristics for middle-aged workers using decision tree analysis. To do this, data from the 25th wave of the Korean Labor Panel (year 2022) was utilized, with a study sample 4,570. First, the factor with the most significant impact on employment according to gender was identified as 'work hours format.' When working full-time, the percentage decreased by 36.5% for women and increased by 63.5% for men. For part-time work, the percentage increased significantly by 85.5% for women and decreased by 14.5% for men. Second, the factor with the most significant impact on employment according to age range was identified as 'highest education level.' For those with a high school education or below, the percentage decreased by 38.2% for ages 40-49 and increased by 61.8% for ages 50-59. For those with a college degree or higher, the percentage increased by 66.0% for ages 40-49 and 70.0% for those with an associate degree. Third, summarizing the study results, the proportion of men is higher for individuals with a college degree or higher, working full-time, and having high job satisfaction. On the other hand, the proportion of women is higher for those working part-time and having a high level of welfare benefits. Additionally, for individuals with an associate degree, stable employment, and job satisfaction, the proportion of those in their 40s is higher. For those with a high school education or below, working in non-office jobs, and having unstable employment, the proportion of those in their 50s is higher. Given that middle-aged workers are more likely to withdraw from the labor market as they age, continuous evaluation of educational training and policy support for job sustainability is necessary. There is a need for support to maintain quality employment even after reemployment.

In accordance with the DUS multiscale scoring standards, a study was conducted at Farmer’s Field in Vadapalani village of Erode district, Tamil Nadu to characterize twenty black turmeric genotypes for sixteen characters. Three of the examined characteristics viz., Leaf color (ventral side), Leaf margin, and Number of mother rhizome were found monomorphic. Seven characteristics were dimorphic and six were polymorphic. Tall plants with lengthy petioles, lamina lengths, and broad leaves were regarded as a plant morphological trait for choosing the best genotype (BTG 6, BTG 11, BTG 12, BTG 15, BTG 16, BTG 17, BTG 19) that are adaptable to local conditions. Black turmeric rhizome variations in inner core color have drawn attention. The inner core of the rhizome’s greenish-blue color can be used to identify the genotype BTG3. Earliness can be a sign for genotypes BTG6, BTG11, BTG15, and BTG19 because they were shown to have short-duration types with less than 210 days. The differences seen with DUS characters provide a clear window for selection based on desired morphological characteristics that may be used for selecting individuals based on particular traits.

Analyzing the Impact of Employee Perks on Organizational Turnover in the Pharmaceutical Sector of Bangladesh
Authors: Jahan Kawsar , Jabin Israt
Published: April 2024

This study explores the impact of employee benefits on organizational earnings within the pharmaceutical sector in Bangladesh, an emerging economy. To conduct this investigation, researchers gathered pertinent data from the annual reports of 26 pharmaceutical companies listed on the Dhaka Stock Exchange (DSE), spanning the period 2017–2021. The primary variable under scrutiny is the employee benefits ratio (EBR), calculated by dividing the total benefits, excluding regular salaries and wages, by the total revenue. Additionally, the study examines the association between the salaries and wages ratio (SWR) and firm turnover. Focusing on these two key variables, the research also incorporates various control factors— namely, leverage, firm age, tangibility, liquidity, firm size, growth, and non-debt tax shield—to enhance the model's robustness. Organizational turnover are measured using return on assets (ROA) and return on equity (ROE) as the dependent variables. The panel-corrected standard error regression analysis reveals that the employee benefits ratio (EBR) and salaries and wages ratio (SWR) exert a significant positive influence on ROA. This implies that increased salaries and additional benefits serve as motivational factors for employees, fostering job satisfaction and enhancing performance. However, these variables do not demonstrate a significant association with ROE. Furthermore, factors such as firm age, leverage, tangibility, liquidity, and firm size exhibit a notable impact on firm performance. These findings collectively contribute to a comprehensive understanding of the relationship between employee benefits, organizational turnover and will help organizations to design their incentive programs effectively.

Comparative Analysis of DG Units with Shunt Capacitive Banks on the Improvement of Voltage Profiles in Distribution Networks.
Authors: Mohammed Haruna , Nwohu M.N.
Published: April 2024

Electrical distribution systems’ reliability is a critical parameter for electrical networks and their end-users. Among the different parameters associated with these systems’ reliability, voltage proﬁle is most commonly affected in the electrical network due to different internal and external parameters such as lines and feeders’ impedance, system overloads, and increments on end-users. A poor voltage profile can have adverse impacts on the end user, such as long-term harm to their electric and electronic devices. For both consumers and companies that provide electricity, a low voltage profile thus leads to a loss of power. The Distributed Generation (DG) system is a viable option to improve voltage profiles while conserving the environment by unlocking the usage of any renewable energies following recent technological advancements and environmental concerns. This article proposes an alternative method to enhance voltage proﬁles in a distribution network (Abuja Electricity Distribution Company, AEDC) by comparing the most effective approach for power losses and voltage profile compensation through DGs and capacitor banks. Detailed simulations are conducted to explain and validate the results with the optimum system voltage improvement and loss reduction. This work has found that the voltage proﬁles are more enhanced with DG units compared to capacitor banks. The power losses were reduced from the initial value of 1196.4 kW to 762.4 kW with a saved energy of 36.3% with DG-unit as compared to FC with a power loss reduction of 1005.2 kW (energy saved of 16.0%).

Abstract. Spatial and temporal variations in the level of dust activity can provide valuable information for policymaking and climate research. Recently, Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol products have been successfully used for retrieving dust aerosol optical depth (DAOD), especially over bright dust source areas, and Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) aerosol reanalysis provides DAOD and additionally other dust-aerosol-related parameters. In this study, spatial and temporal variations in dust activity in Australia were analyzed using MODIS and MERRA-2 combined (M&M) DAOD and MERRA-2 near-surface dust concentrations and estimated PM10 for the period 1980–2020. Validation results show that M&M DAOD has an expected error of ±(0.016+0.15τ) compared to the ground observations at the AErosol RObotic NETwork (AERONET) dust storms on populated areas sites. MERRA-2 near-surface dust concentrations show a power-law relationship with visibility data collected at meteorological stations with an r2 value from 0.18 to 0.44, and the estimated MERRA-2 PM10 shows similar temporal variations and correlates with ground-based PM10 data with an r2 value from 0.14 to 0.44 at six selected stations in Australia. Moreover, MERRA-2 horizontal dust flux shows the same major dust pathways as those in previous studies and similar dust emissions and deposition areas identified using ground-based observations. Dust events based on DAOD over eastern Australia are concentrated in the north in December, are concentrated in the south in February, and can occur anywhere in January. Near-surface dust concentration was found to be the highest (over 200 µg m−3) over the center of Lake Eyre basin in central Australia and radially decreased toward the coast to below 20 µg m−3 via the two main pathways in the southwest and northeast. The ratio of near-surface dust concentration to PM10 shows a similar spatial pattern. Total dust emission was estimated to be 40 Mt (megatonnes) per year over the period 1980–2020, of which nearly 50 % was deposited on land and the rest exported away from the Australian continent.

Abstract. Narrowing surface ozone disparities between urban and nonurban areas escalate health risks in densely populated urban zones. A comprehensive understanding of the impact of ozone photochemistry on this transition remains constrained by current knowledge of aerosol effects and the availability of surface monitoring. Here we reconstructed spatiotemporal gapless air quality concentrations using a novel transformer deep learning (DL) framework capable of perceiving spatiotemporal dynamics to analyze ozone urban–nonurban differences. Subsequently, the photochemical effect on these discrepancies was analyzed by elucidating shifts in ozone regimes inferred from an interpretable machine learning method. The evaluations of the model exhibited an average out-of-sample cross-validation coefficient of determination of 0.96, 0.92, and 0.95 for ozone, nitrogen dioxide, and fine particulate matter (PM2.5), respectively. The ozone sensitivity in nonurban areas, dominated by a nitrogen-oxide-limited (NOx-limited) regime, was observed to shift towards increased sensitivity to volatile organic compounds (VOCs) when extended to urban areas. A third “aerosol-inhibited” regime was identified in the Jiaodong Peninsula, where the uptake of hydroperoxyl radicals onto aerosols suppressed ozone production under low NOx levels during summertime. The reduction of PM2.5 could increase the sensitivity of ozone to VOCs, necessitating more stringent VOC emission abatement for urban ozone mitigation. In 2020, urban ozone levels in Shandong surpassed those in nonurban areas, primarily due to a more pronounced decrease in the latter resulting from stronger aerosol suppression effects and less reduction in PM2.5. This case study demonstrates the critical need for advanced spatially resolved models and interpretable analysis in tackling ozone pollution challenges.

Published: April 2024

Abstract. A new upper stratospheric (35–60 km) temperature data product has been produced using Optical Spectrograph and InfraRed Imager System (OSIRIS) limb-scattered spectra that now spans over 22 years. Temperature is calculated by first estimating the Rayleigh scattering signal and then integrating hydrostatic balance combined with the ideal gas law. Uncertainties are estimated to be 1–5 K, with a vertical resolution of 3–4 km. Correlative comparisons with the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) and the Microwave Limb Sounder on Aura (MLS) are consistent with these uncertainty estimates and generally have no regions of statistically significant drift. The data product has been publicly released as part of the nominal OSIRIS v7.3 processing.

Abstract. Due to large losses of seagrass meadows worldwide, restoration is proposed as a key strategy for increasing coastal resilience and recovery. The emergence of a seagrass meadow is expected to substantially amplify biodiversity and enhance benthic metabolism by increasing primary productivity and respiration. Nevertheless, open questions remain regarding the metabolic balance of aging seagrass meadows and the roles benthic communities within the seagrass ecosystem play in overall metabolism. To address these questions, we investigated a chronosequence of bare sediments and adjacent Zostera marina meadows of 3 and 7 years since restoration alongside a natural meadow located within a high-temperate marine embayment in Gåsö, Sweden. We combined continuous measurements of O2 fluxes using underwater eddy covariance with dissolved inorganic carbon (DIC) and O2 fluxes from benthic chambers during the productive season (July). Based on the ratio between O2 and DIC, we derived site-specific photosynthetic and respiratory quotients, enabling the conversion of eddy covariance fluxes to DIC. We assessed benthic diversity parameters as potential drivers of metabolic flux variability. We observed high rates of gross primary productivity (GPP) spanning −18 to −82 mmolDICm-2d-1, which increased progressively with meadow age. Community respiration (CR) mirrored the GPP trend, and all meadows were net heterotrophic (GPP < CR), with net community productivity (NCP) ranging from 16 to 28 mmolDICm-2d-1. While autotrophic biomass did not increase with meadow age, macrophyte diversity did, elucidating potential effects of niche complementarity among macrophytes on community metabolism. These findings provide valuable insights into how community composition and meadow development relate to ecosystem functioning, highlighting potential tradeoffs between carbon uptake and biodiversity.
