Effect Analysis of Material Properties on Thermo-Electric Generator Performance
Authors: Ponangi Babu Rao , Mutagi Megha , Bali Gaurav
Published: September 2024

Residual thermal energy, a by-product of automobiles, contributes notably to climate change and global warming. This energy is produced as exhaust gases in vehicles with internal combustion engines and as heat from batteries and fuel cells in eco-friendly vehicles. A thermo-electric generator (TEG) can transform this waste heat into useful electrical energy. The efficiency of the TEG is influenced by several factors, including the properties of the materials used, the geometrical design (form factor), and the conditions under which it operates.

In this study, we examine how the choice of materials for the semiconductors, electrodes, ceramics, and joining components influences the overall performance of the TEG. We evaluate the TEG’s performance based on output power, and efficiency. The findings from these measurements allow us to determine which material and its properties significantly impact the TEG’s performance. For optimal TEG performance, seek materials with high Seebeck coefficients, low thermal conductivities, and low specific resistivities. For all other components (electrodes, ceramic plates, and thermal interface materials), using higher thermal conductivity materials results in higher TEG performance.
Minimization of Power Consumption in Fuel Cell Air Feed in System in Fuel Cell Electric Vehicle
Authors: Choubey Ayush , Ponangi Babu Rao , Shah Saurabh , Munirajappa Chandrashekara
Published: September 2024

The air supply system in a Fuel Cell Electric Vehicle (FCEV) provides the oxygen needed for the fuel cell to react with hydrogen. The air compressor, being the main component of the air supply subsystem, has the highest power consumption among all auxiliary loads in an FCEV. Therefore, efficient control of the air supply system is critical for improving fuel cell performance.

The air supply system has a slow response to dynamic load changes. Due to its weak transient response, an overshoot in airflow can lead to an increase in auxiliary power loss, while an undershoot can cause a delay in meeting power requirements. Thus, reducing transients is a crucial factor in improving the overall system efficiency.

In conventional control, the battery supplies additional power needed during dynamic load changes. During high dynamic load changes, there is frequent switching between the battery and the fuel cell. This frequent charging and discharging of the battery can impact its longevity.

Currently, the control of the air compressor in the fuel cell is reactive. The proposed solution aims to reduce the losses in the air compressor by predictively tuning the gain parameters of the controller and optimizing the power split between the fuel cell stack and the battery using the predicted vehicle load.

Predictive tuning helps in reducing transients in fuel cell air compressor control, ensuring smooth power transfer and minimal losses due to the air system. The proposed method uses the topography ahead information and other vehicle parameters to estimate the load. The air compressor model, coupled with predictive and adaptive tuning, suggests the controller parameters that minimize the air system losses. The switching strategy between the fuel cell stack power and battery power takes the dynamics in predicted load changes into consideration.

Published: September 2024

With the advent of electric vehicles and advance trends in power train there is an increasing demand in improving the overall cabin comfort level. This is especially true when it comes to electric vehicles as the major source of sound other than the external flows would be from the HVAC systems for the vehicle. The noise source can be further divided on structural noise and flow induced noise; the paper would be focusing on prediction of flow induced noise levels. Flow induced noise by the HVAC’s would be critical since there are significant advancements in the cabin insulations/materials from externally generated noise sources.

Automotive HVAC system consist of complex flow paths, blower, flaps, ducts, and vents which are the main source of noise generation in HVAC systems. With packaging space beneath the IP been premium, changes proposed to improve the noise levels are expensive and are understood at later level/phase of product development cycle. This paper puts forward an approach to evaluate the air induced noise levels for HVAC systems/components which can be used in early phase of development cycle. Computational Aeroacoustics (CAA) is proposed to be used to predict the sound generation and propagation level for the given microphone positions. The noise source can be identified and improved in early phase of development cycle which if done in later phase would require an expensive change.

The process for prediction of noise has been validated and tested with good correlations between the two approaches.

Published: September 2024

In today's fast-paced lifestyle, people spend a maximum amount of time for traveling, leading to a heightened demand for thermal comfort. Automotive HVAC play a crucial role in providing conditioned air to ensure comfort while traveling. Evaluating HVAC systems performance including delivery systems, heat exchanger efficiency, air thermal mixing zones, and temperature distribution are essential to maintain fuel economy and modern vehicle styling. However, accurately predicting cooling/heating performance using CFD simulations poses challenges due to the complex nature of heat exchanger modeling, which demands substantial computational resources and time.

This paper presents the development of CFD modeling capabilities for predicting temperature distribution at duct outlet grills for defrost mode. Additionally, it assesses heater performance under maximum hot conditions. STAR-CCM+ software is employed to model the entire system, with the heater and evaporator core represented as porous regions. The inertial and viscous resistances in these regions are defined using Coil Designer 1-D simulation result data which includes air side pressure drop at different airflow rates for both heater and evaporator.

A dual stream heat exchanger model within STAR-CCM+ is utilized to create the heater topology and establish a heater interface between two fluid regions. One-dimensional simulation result data from the heater, showcasing heat transfer at various airflow rates with a water flow rate of 6 LPM, is imported into the dual stream heat exchanger model. The dual stream heat exchanger methodology enables comprehensive system unit simulation with significantly reduced computational costs and faster solving times.

Authors: Parayil Paulson , Kame Shubham , Goel Arunkumar
Published: September 2024

HVAC is one of the main components on AC system on passenger car. Air flow distribution through the HVAC duct outlet as well as foot outlet is controlled mainly through HVAC kinematic mechanism. Kinematic mechanism mainly controls the air flow distribution and also temperature linearity at the outlet. Blower assembly as well as Kinematic mechanism is mainly two moving components inside HVAC system. Apart from the blower noise, another important noise generating area is kinematic noise. Due to poor cam profile and pin reaction force inside cam profile, there is high reaction force and hence produce noise. Due to different kinematic mode travel (face, foot and defrost), the pin has to be moved inside the cam profile, so pin movement & interference due to the stroke length travel leads a higher noise.

The present paper describes the noise prediction based on simulation methodology of HVAC kinematic mechanism and damper (Doors) movement. First kinematic simulation of baseline model is being conducted considering all design parameters. During simulation, fluid pressure also considered for the simulation for different modes which impacts force on kinematic doors. CAD data from CATIA software is used as parasolid format which is being used for MBD model. MBD model created on motion view software and thereafter solved using motion view. From the result, Torque as well as reaction force also calculated from MBD analysis. The pin reaction force been converted into noise which is been validated with test result.

Published: September 2024

The proposed smart, efficient eco-cooling strategy leverages the AC system's efficiency sensitivity to the vehicle speed and the thermal storage of the cabin to coordinate the AC operation with the vehicle speed profile by actively shifting the AC thermal load toward the more efficient region at higher vehicle speeds.

An investigation is now being conducted on vehicle cabin climate control systems to lower energy consumption and enhance battery electric vehicle range when in pure electric mode. OEMs of electric vehicles are always searching for novel concepts that will extend the driving range of their vehicles. Basically, an air conditioning system needs high-voltage power from high-voltage battery packs to keep the interior of the cabin in a comfortable temperature range during the summer. In order to meet these demands, the AC system in electric vehicles becomes an additional power consumer.

This smart ECO AC system consists of the importance and impact of the various components of the AC system, as well as the techniques followed by researchers to optimize the performance and decrease the power consumption of the AC system to expand the range of vehicles. We also look at the impact of the thermal load and the volume of space that needs to be conditioned. We conclude this review with the different options for the reduction of power consumption with ECO AC to occupant space as the solution for reducing the energy consumption or extending the range of the electric vehicle. Smart, efficient ECO AC systems reduce power consumption by 6–7% in small commercial electric vehicles.

Authors: Gudi Abhay , Bonala Sastry
Published: September 2024

To understand effect of thermal hazards of LIBs during TR event, it is important to study flame propagation behaviour of LIBs during storage and transport applications. The process of flame propagation involves complex phenomena of gas phase behavior of LIBs. Present paper attempts a numerical investigation to portray this complex phenomenon. This paper investigates 18650 lithium cell considering two different chemistries NMC and LFP.

A 3D numerical CFD model has been constructed to predict the gas phase behavior, threshold internal pressure, and cell gas venting of an 18650-lithium cell under thermal runaway conditions. The gas phase processes are modelled using the 4-equation thermal abuse model, while the cell's venting mechanism is modelled using Darcy's equation. Present work is divided into two parts: 1) Venting gas Internal pressure prediction 2) modeling thermal runaway event. Both procedures are implemented on two different cell chemistries to understand and evaluate following parameters: Vent gas internal pressure, Flame propagation during thermal runaway, flame length comparison, total heat prediction and temperature of flame during thermal runaway event. Cells with NMC and LFP chemistries are modeled and compared at 100% SOC condition. The comparison of the above numerical output parameters for both chemistries reveals that, in contrast to 18650 NMC cell, the flame length of the LFP cell after a thermal runaway event is 74% lower. According to the study, the threshold internal pressure at the valve opening of the LFP cell is 68% lower than that of the NMC cell. Thus, researchers and industry professionals can comprehend the 3D nature of flame propagation as well as the mechanics of cell venting thanks to this precise 3D modelling method. The numerical model uses commercial 3D ANSYS FLUENT code to adapt the well-known RANS technique for modelling the thermal runaway event.

Published: September 2024

Automotive cooling module system consists of condenser, radiator and intercooler which is used for thermal management of vehicle. Condenser helps to reject cabin heat, radiator to reject engine heat and intercooler rejects charged air heat to ambient. CRFM (Condenser, Radiator and Fan module) is conventionally packaged under the bonnet of passenger vehicle. Fan circulate airflow through heat exchangers and has primary role of airflow delivery. While performing vehicle level thermal management duty, fan noise is generated from CRFM and fan noise is considered as an important design attribute of CRFM. Many researchers have done fan noise simulation at component level and very limited literatures at vehicle (system) level simulation are available. Customer perceives noise from outside of the vehicle and it is important to predict fan noise at vehicle level at various operating speeds. Such simulations are transient in nature and modeling complexity demands high computational cost. Current paper discusses simulation methodology for component and vehicle level simulation. Results of both scenarios are compared with experimental results and correlation established is discussed in this paper.

Vehicle level and component level fan noise simulations are carried out in LBM (Lattice Boltzman Method) based software and physical tests were conducted in semi anechoic chamber. This paper also demonstrates test and simulation approach used to perform this work. In current process, vehicle level and component level simulation correlation is established. Current methodology can be used for design ranking and will further assist in providing design countermeasures to reduce cooling module fan related noise during early product development.

A Study on Cabin Heat Load Reduction Using Solar Reflective Glasses in Automotive Application
Authors: Kumar Sunny , Venu Santosh , Raj Shivam , Kandekar Ambadas
Published: September 2024

Over the past few decades, there has been a notable increase in stakeholder’s attention on Earth's climate. The automotive industry, being a major contributor to this phenomenon, has been endeavoring to mitigate its impact through various measures. These efforts include reducing emissions in existing internal combustion engine (ICE) vehicles and promoting electric vehicles (EVs) as a feasible alternative for consumers. Despite these initiatives, there remains a persistent challenge in improving the fuel economy and driving range of vehicles.

India, located along the Tropic of Cancer, experiences both tropical and subtropical climates. As a result, a substantial portion of the total heat absorbed is from solar radiation. The higher heat load necessitates extensive use of air conditioning (AC) systems, which significantly contributes to the overall power consumption of vehicles. Various measures are being implemented to mitigate this heat load and enhance the efficiency of AC operations. This study aims to investigate the properties of different types of photochromatic glass and their effects on cabin heat load. Various proposals involving solar-coated glass, including absorptive and reflective types as well as combinations of these types are examined. Digital simulations are conducted to identify the most suitable alternatives for glass and their combinations.

In this study, a combination of the Lattice-Boltzmann (LBM) based Power FLOW solver and the Finite Element based solver is utilized to simulate long transient soak and cool down processes. Furthermore, human thermal physiology is incorporated into the model to account for subjective evaluations of the in-cabin thermal environment. The Berkeley Comfort Model library, available in software, is employed for this purpose. This model addresses vasodilation and vasoconstriction effects based on external ambient conditions, as well as the influence of clothing and passenger metabolic rate. Digital simulations indicate that solar-coated reflecting-type glasses exhibit promising results.

The mentioned glass is installed in vehicles, and various trials are conducted under different conditions, including highway cycles, city cycles, and range trials, in both moderate and severe ambient conditions. Temperatures inside the cabin, at the grill level, and at most of touch points including glass surface are recorded for trials. The rate of rise of temperature during soaking reduced by ~15-18 % at cabin level and by ~32-35 % on touchpoints. In the vehicle-level test results, it is observed that touch point temperatures decrease by ~11-12°C, and air conditioning power consumption reduced by ~9-13%.
CFD Method for Predicting Thermal Cool-Down Behavior of a School Bus Cabin
Authors: Sharma Shantanu , Singh Ramanand , Zucker James , Moore Chris
Published: September 2024

Passenger vehicles like buses tend to soak up heat when they are parked under an open sky. The temperatures inside the vehicle can get very high during daytime due to heating, which reduces the thermal comfort levels. All three modes of heat transfer, i.e., conduction, convection and radiation contribute to the heating process. Cool-down tests are performed to replicate this thermal behaviour and evaluate the time required for cooling the internal bus volume to comfortable temperatures. The phenomenon can also be analysed using CFD, and accounts of numerous such studies are available however, the effects of all three modes of heat transfer for practical application are rarely studied. In view of this, an effort has been made to develop a fast and reasonably accurate transient numerical method to predict the thermal behaviour of the cool-down process for a school bus cabin. The effects of all three modes of heating (conduction, convection, and solar radiation) have been evaluated, and the method has been validated using test data. Comparison of CFD & test data shows that CFD tends to predict faster cooling, which can be attributed to lesser thermal mass inside the bus due to the simplification of the bus model for practical purposes of reducing the simulation time. The overall deviation of the CFD results from the test data is in the order of 3-8%, which was found to be reasonable given the computational time, however, the accuracy of the method can be further improved by evaluating different turbulence models. The method can be used for comparing the cooling performance of various evaporators and evaluate passenger thermal comfort inside the bus cabin, ultimately help in reducing the energy consumption of the vehicle.

Published: September 2024

India features diverse climatic zones, spanning from tropical in south to alpine in north. Since most of the regions are hot, vehicle cabin cooling analysis dominates over heating analysis, creating a notable technology gap that exists in cabin heating. Nonetheless, in colder regions of India and Europe, maintaining optimal cabin heating is crucial for human comfort. Furthermore, in climates prone to mist and frost formation, ensuring the accuracy and effectiveness of cabin heating mechanisms becomes crucial, as it directly correlates with safety considerations that comes prior to mere comfort requirements. To reduce the technology gap and physical testing in cold climatic conditions this work is proposed, which will enable us to predict cabin heating performance of vehicle on highway running as well as in stationary condition for Electric Vehicles (EV) and Internal Combustion Engine Vehicles (ICEV) in 1D Computer Aided Engineering (CAE) software. A detailed Transient Cabin Heating Model (T-CHM) has been developed with an accuracy of > 95%, to predict the temperatures of various components in a vehicle's heating system, including heater core, radiator, engine and Positive Temperature Coefficient (PTC) heater. This model can accurately predict the average temperatures in the vents and cabin during the critical phase when the vehicle is starting in cold climatic conditions. The robustness of model has been evaluated through comprehensive testing under various climatic conditions, with subsequent comparisons made against experimental data for vehicles and then temperatures are predicted for upcoming programs to optimize the components without extensive physical trials. This can be further enhanced for EVs by making an integrated circuit with battery heating and heat pump for efficient Heat Flux Management System (HFMS) which will enable us to predict and improve range of vehicles by minimizing separate power sources for thermal management and hence better energy utilization.

Published: September 2024

A well-designed cooling system is crucial in construction machines for efficient heat dissipation from vital components, including the Radiator(RAD), Oil Cooler (OC) and Intercooler (IC). The radiator ensures optimal engine performance and longevity by maintaining a stable operating temperature. Oil Coolers preserve hydraulic system efficiency. Inter Coolers optimize engine performance through denser intake air. The robust cooling system enhances system reliability, reduces downtime, avoid overdesigned system, and increases operator safety in demanding construction environments. The size and location of heat exchangers are critical in cooling system design. Using 1D simulation tool KULI for cooling system design offers the benefits of comprehensive system simulation, optimization of thermal management, reduced development time and costs, enhanced system reliability, improved integration with other systems, and real-world testing and validation. The tool enables time and cost-effective 1D heat transfer analysis, facilitating design of experiments. This analysis guides the design process to the next level, where the finalized design can be verified using CFD analysis for the optimal case, avoiding multiple 3D simulations which consume a lot of time & cost. This paper talks about KULI software to analyze the sizing and placement of heat exchangers within given size constraints for a new engine packaging in a construction machine. The approach helped to determine the optimal size and positioning of the heat exchangers while considering heat transfer, fluid flow, pressure drops, and temperature distribution. This data-driven approach allowed to design an efficient cooling system that ensures reliable performance of critical components.

Authors: Carnazzo Salvatore Michele , Balconara Desirèe , Comisi Francesco Fabrizio , Ruggieri Martino
Published: September 2024

Seizures and epilepsies pose significant challenges in pediatric populations, necessitating precise classification and effective management. The International League Against Epilepsy updated its classification system in 2017 to standardize epilepsy care. This study investigated melatonin, a neurohormone known for its role in circadian rhythm regulation, and its potential to enhance the diagnosis, management, and quality of life of pediatric epilepsy patients. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review was conducted to explore the relationship between melatonin and pediatric epilepsies. PubMed searches were performed using specific search terms, with eligibility criteria including studies on melatonin’s pathophysiological, biochemical, and therapeutic effects in pediatric epilepsy. Studies involving patients aged 0-18 years were published between 2003 and 2023. Four-teen studies with 898 pediatric patients were included. Melatonin was administered as an adjunct to antiepileptic therapy with the aim of alleviating disorders associated with epileptic encephalopathies or assisting electroencephalogram procedures. Findings were varied: Some studies indicated a reduction in seizure frequency with melatonin, while others provided inconclusive results. Improvements in sleep disorders related to epilepsy were noted with melatonin supplementation, which indirectly enhanced the overall quality of life. Melatonin has potential as an adjunctive therapy for pediatric epilepsy, with positive effects on seizure frequency and sleep quality. However, methodological limitations in some studies and inconclusive data underscore the need for further research to determine the efficacy of melatonin in pediatric epilepsy management. The diverse potential of melatonin in treating neurological disorders highlights the importance of continued, comprehensive research into its therapeutic application.
Jeszcze jeden klerk. Jerzy Kowalski wobec myśli Karola Irzykowskiego
Authors: Sadkowska Katarzyna
Published: September 2024

The author compares Karol Irzykowski’s thoughts on the role of clerks with the project of Radical Intellectualism by Jerzy Kowalski, showing the similarities and differences. Kowalski was a scholar and artist-writer. He assigned intellectuals the most important role in controlling and shaping political power, namely establishing good governance. An intellectual was supposed to be a non-partisan specialist, gaining people’s trust thanks to knowledge and searching for non-ideological, good solutions. Richard Coudenhove-Kalergi’s theory of hyperethics, quoted in the article, explains the contradictions of Irzykowski’s unique attitude towards clerks.
Strażnik snów. O życiopisaniu Karola Irzykowskiego
Authors: Jauksz Marcin
Published: September 2024

The purpose of the article is to trace “relationships with Pałuba” through Karol Irzykowski’s dreams, or rather: the connections between Pałuba and entries in the diary of the aspiring writer from the 1890s, in which self-analysis and reflections on his own work abound with reports of dreams about Zosia Piotrowska, a cousin with whom Irzykowski was in love. The parallel between dreams about love and dreams about creativity is strong, thanks to the neo-Romantic inclinations of the young Irzykowski. It is revealing of his strong rationalism that allows his unfinished project of “dream analysis” to be placed next to Freud’s as one of the key symptoms of modernist revaluation.
Alegoryzacje „dnia Gniewu”. O utworach Jana Kasprowicza pisanych „ginącemu światu”
Authors: Milan Rafał
Published: September 2024

The text is an attempt to indicate the common places in the works published by Kasprowicz as volume VI of his Dzieła poetyckie [Poetic Works]. In the field of research interest, the basic human experiences are – according to Kasprowicz – pain, associated fear and literary strategies for taming them. The cycles Ginącemu światu [To the Dying World] and Salve Regina, as well as the poems from the volume O bohaterskim koniu i walącym się domu [Of the Heroic Horse and the Wrecking House] are read in the perspective of a modern allegory. Detailed interpretations use the concepts of classical psychoanalysis (such as fetish, symptoms, denial). The source of inspiration also comes from Walter Benjamin’s proposed description of the disappearance of experience and the disintegration of significant structures – which can be recognised as phenomena characteristic of modernity.

Published: September 2024

Researchers have explored neurodiversity in terms of gender, gender identity and expression, masking, and more, yet the focus is often on neurodiversity as synonymous with autism. There remains a challenge to expand the body of neurodiversity research that is broader than autism. In my article, neurodiversity will be discussed as an element of the broad human condition, rather than a singular state or condition of impairment isolated to a portion of the population to delineate the paradigm based on neurological variations from medical and social models. This paper was designed to offer a “how to” for conducting research into neurodiversity through an appreciative lens as it serves as an element of human intersectionality, using individual narrative research designs such as autoethnography and Personal Network Analysis (PNA) as tools for inquiry. The potential value of such research is that it may result in calls to action for researchers, practitioners, and educators that serve to lift neurodiversity by gathering stories directly from neurodiverse people to show the common nature of experience shared by all.

This research focuses on developing LegitCheck's website interface by applying the Parallax Scrolling Effect technique, which is considered as a potential solution to support the startup's promotional strategy. LegitCheck, as a startup that needs an effective way to introduce its services and business concept to consumers and brands, requires a website that can serve as an attractive promotional medium as well as a comprehensive information center. The purpose of this research is to examine the effectiveness of the Parallax Scrolling Effect technique compared to a website without the effect in increasing the effectiveness of the LegitCheck website as a promotional tool. The research method used includes the design and implementation of the Parallax Scrolling Effect technique on the LegitCheck website, followed by evaluation using the A/B testing method. The results showed that the implementation of the Parallax Scrolling Effect technique provided significant benefits, including improved information accuracy, service quality, user satisfaction, and company net profit. Although there are constraints related to page loading speed, the majority of respondents prefer websites with Parallax Scrolling Effect because it provides a more interactive and engaging experience. The implication of this study is that the use of Parallax Scrolling Effect can be an effective strategy for startups such as LegitCheck to increase interaction with users, strengthen brand image, and increase the effectiveness of the website as a promotional tool, although it is necessary to pay attention to technical aspects such as page loading speed to minimize potential disruptions to the user experience.

Authors: Tamara Yolanda
Published: September 2024

The digital era has significantly transformed the behavior of Indonesian consumers, particularly with the emergence of shopping trends through live streaming on e-commerce platforms. This study investigates the influence of the Big Five personality traits, financial perception, and external factors on the tendency for impulsive buying during live streaming. By integrating theories from consumer behavior and psychology, this research explores how self-control, money availability, economic well-being, time pressure, and sales promotions affect the tendency for impulsive buying. Using an online survey distributed among Indonesian consumers, this study provides insights into how these factors interact in the context of digital shopping during live streaming purchases. The findings aim to help e-commerce businesses optimize their sales strategies and offer recommendations to enhance consumer satisfaction. The results show a negative influence between self-control and the tendency for impulsive buying, with conscientiousness and extraversion personality traits showing significant effects on impulsive buying. The perception of money availability has a positive influence on the tendency for impulsive buying. From an external factors perspective, sales promotions positively influence purchase intentions, while time pressure negatively affects buying intentions or the tendency for impulsive buying. These insights aim to assist digital marketers and e-commerce businesses in optimizing their sales strategies and improving consumer satisfaction.

Published: September 2024

The implementation of the Regulation of the Minister of Health of the Republic of Indonesia Number 12 of 2017 concerning the Implementation of Immunization in the Context of Fulfilling Children's Right to Health at Integrated Service Posts (Posyandu) in the Cimandala Village area, Bogor Regency is the focus of this research to evaluate the effectiveness of its implementation. This study aims to assess the extent of the implementation of immunization policies in accordance with applicable regulations and analyze the factors that affect immunization coverage in the region. This study uses a descriptive approach with analysis of complete basic immunization coverage data (IDL) and evaluation of the efforts of health workers and health cadres in the implementation of immunization at Posyandu. The implementation of the Minister of Health Regulation Number 12 of 2017 in the Posyandu in the Cimandala Village area has not been optimal. Data shows that IDL coverage is below the national target, which is 75.71% in 2021, 69.83% in 2022, and 67.31% in 2023. Low IDL coverage contributes to the persistence of immunization-preventable cases of diseases, such as tuberculosis, pneumonia, and measles in children under 5 years of age. The efforts of health workers and health cadres in the implementation of immunization have also not met expectations, showing the need for improvement in the implementation of the policy.

The career ladder system has proven to be effective in supporting nurses' professional development. However, its implementation has not been optimal, partly due to nurses' low motivation. Therefore, a strategy to develop an electronically integrated career ladder information management system, SIMCAR LASTRI, is needed to improve career ladder implementation. This study aims to analyze the effect of SIMCAR LASTRI development on nurses' motivation in implementing career ladder in Tanjungpinang. This study used an analytic quantitative method with a pre-post quasi-experiment design without a control group. Application development was conducted through ADDIE (Analyze, Design, Development, Implementation, Evaluation) and RAD (Rapid Application Development) methods. The research subjects were executive nurses (n=76) with total sampling. Bivariate tests were conducted using the Wilcoxon Signed Rank Test. The results showed a significant effect on nurses' motivation before and after using the web-based SIMCAR LASTRI application, with a p value = 0.000 <0.05. The implementation of web-based SIMCAR LASTRI is feasible and has a significant influence on nurses' motivation in implementing career paths. SIMCAR LASTRI application can be implemented in all hospitals.
THE EFFECTS OF MONEY PRIMING ON RISK-TAKING BEHAVIOR
Authors: Okamura Yasuto
Published: September 2024

Studies have found that exposure to money influences human behaviors. This study examines the effects of money priming on risk-taking. When either exposed or not exposed to money priming, participants responded to the likelihood that they would engage in unsafe behaviors and the perceived risk of these behaviors. The results revealed that individuals tended to exhibit more risky behavior when they were exposed to money priming. The theoretical implications of these findings and various directions for further research are discussed.
