Published: March 2024

Ginseng holds high medicinal and cosmetic value, with stem and leaf extracts garnering attention for their abundant bioactive ingredients. Meanwhile, fermentation can enhance the effectiveness of cosmetics. The aim of this study was to optimize ginseng fermentation to produce functional cosmetics. Ginseng stem and leaf extracts were fermented with five different strains of lactic acid bacteria. Using 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl radical (·OH), and superoxide anion (O2·−) scavenging activities as indicators, the fermentation process was optimized via response surface methodology. Finally, validation of the antioxidant activity of the optimized fermentation broth was performed using human skin cells (HaCaT and BJ cells). Based on the antioxidant potency composite comprehensive index, Lactiplantibacillus plantarum 1.140 was selected, and the optimized parameters were a fermentation time of 35.50 h, an inoculum size of 2.45%, and a temperature of 28.20 °C. Optimized fermentation boosted antioxidant activity: DPPH scavenging activity increased by 25.00%, ·OH by 94.00%, and O2·− by 73.00%. Only the rare ginsenoside Rg5 showed a substantial rise in content among the 11 ginsenosides examined after fermentation. Furthermore, the flavonoid content and ·OH scavenging activity were significantly negatively correlated (r = −1.00, p < 0.05), while the Rh1 content and O2·− scavenging activity were significantly positively correlated (r = 0.998, p < 0.05). Both the 0.06% (v/v) and 0.25% (v/v) concentrations of the optimized broth significantly promoted cell proliferation, and notable protective effects against oxidative damage were observed in HaCaT cells when the broth was at 0.06%. Collectively, we demonstrated that ginseng fermentation extract effectively eliminates free radicals, preventing and repairing cellular oxidative damage. This study has identified new options for the use of fermented ginseng in functional cosmetics.

Published: March 2024

Psoriasis is a common chronic inflammatory disease, but most of its current treatments come with a high risk of side effects. As one of the world’s top three beverages, tea has a traditional history of being used as a treatment for skin conditions due to its high safety profile, anti-inflammatory and other properties. In this study, we investigated the anti-psoriasis effects of ethanol extracts of black tea, green tea and white tea from southeastern China. The compositions of the tea extracts (TEs) were first determined by UPLC-Q-Exactive-Orbitrap MS and then genetic analysis, antibacterial, anti-inflammatory, and immunocompetence assays were performed. Imiquimod was used to establish a mouse model of psoriasis-like dermatitis and treating with the extracts to examine their efficacy. A total of 88 chemical components, mainly phenols and organic acids, were identified from the TEs. These TEs ameliorated skin damage and they all reduced the expression of cytokines IL-17 and TNF-α. By analyzing the genes, TEs may affect the inflammatory signaling pathway by regulating the metabolic changes. In addition, TEs can significantly scavenge ROS, NO, and inhibit cellular inflammation. In conclusion, this study examined the inhibitory effects of three TEs on psoriasis and their potential as nutritional supplements for the treatment of skin inflammation.

(1) Background: Clinical simulation is an educational approach that aims to replicate real-life scenarios. Its primary goal is to help nursing students acquire the necessary knowledge and skills to perform effectively in clinical settings. This study focuses on the relationship between communication skills, evidence-based practice (EBP), and clinical simulation. We aimed to assess how communication skills and EBP competencies affect nursing students’ performance in simulated clinical scenarios. (2) Methods: We conducted an observational, cross-sectional study with 180 third-year nursing students at the University of Murcia. We used validated instruments to evaluate the students’ EBP competencies, communication skills, non-technical skills, and nursing interventions in simulated scenarios. (3) Results: The results showed that the students had varying competencies in EBP and communication skills. However, there was a positive and statistically significant correlation (p < 0.001) between these variables, non-technical skills, and the simulated clinical scenario nursing interventions. Our regression models revealed that communication skills and EBP competence significantly influenced the performance of the student nurses regarding their clinical and non-technical skills in the simulated scenarios. (4) Conclusions: Communication skills and EBP competencies predict performance in simulated scenarios for nursing students.

Published: March 2024

Dredged sediment contaminated with heavy metals can be remediated through phytoremediation. The main challenge in phytoremediation is the limited availability of heavy metals for plant uptake, particularly in multi-contaminated soil or sediment. This study aimed to assess the effect of the nitrogen fertilizers (ammonium nitrate (AN), ammonium sulfate (AS), and urea (UR)), organic acids (oxalic (OA) and malic (MA) acids), and their combined addition to sediment on enhancing the bioavailability and phytoremediation efficiency of heavy metals. The sediment dredged from Begej Canal (Serbia) had high levels of Cr, Cd, Cu, and Pb and was used in pot experiments to cultivate energy crop rapeseed (Brassica napus), which is known for its tolerance to heavy metals. The highest accumulation and translocation of Cu, Cd, and Pb were observed in the treatment with AN at a dose of 150 mg N/kg (AN150), in which shoot biomass was also the highest. The application of OA and MA increased heavy metal uptake but resulted in the lowest biomass production. A combination of MA with N fertilizers showed high uptake and accumulation of Cr and Cu.

Published: March 2024

Under iron (Fe)-limited conditions, plants have developed strategies for acquiring this essential micronutrient. Several Fe sources have been studied as potential fertilizers, with Fe synthetic chelates being the most used to prevent and correct Fe chlorosis in crops. The determination of the activity of the Fe chelate reductase (FCR) enzyme has long been described in the literature to understand the efficiency of Strategy I plants in acquiring Fe from fertilizers under deficient conditions. Other experiments have focused on the translocation of Fe to the plant to define the effectiveness of Fe fertilizers. Yet, both assays are relevant in knowing the capacity of a novel Fe source and other compounds alleviating Fe chlorosis in Strategy I plants. This work reviews the methodologies that are used in FCR assays to evaluate novel Fe fertilizers, including the factors modulating the results obtained for FCR assay activity, such as the Fe substrate, the Fe level during the growing period and during the FCR assay, the pH, the choice of an in vivo or in vitro method, and the plant species. A discussion of the benefits of the concurrence of FCR and Fe uptake assays is then presented alongside a proposed methodology for assessing the effectiveness of Fe fertilizers, emphasizing the importance of understanding chemical and physiological plant interactions. This methodology unifies key factors that modify FCR activity and combines these with the use of the 57Fe tracer to enhance our comprehension of the efficacy of Fe-based fertilizers’ effectiveness in alleviating Fe chlorosis. This comprehensive approach not only contributes to the fundamental understanding of Fe-deficient Strategy I plants but also establishes a robust method for determining the efficiency of novel sources for correcting Fe deficiency in plants.

Amaranthus is a genus of C4 dicotyledonous herbaceous plant species that are widely distributed in Asia, Africa, Australia, and Europe and are used as grain, vegetables, forages, and ornamental plants. Amaranth species have gained significant attention nowadays as potential sources of nutritious food and industrial products. In this study, we performed a comparative genome analysis of five amaranth species, namely, Amaranthus hypochondriacus, Amaranthus tuberculatus, Amaranthus hybridus, Amaranthus palmeri, and Amaranthus cruentus. The estimated repeat content ranged from 54.49% to 63.26% and was not correlated with the genome sizes. Out of the predicted repeat classes, the majority of repetitive sequences were Long Terminal Repeat (LTR) elements, which account for about 13.91% to 24.89% of all amaranth genomes. Phylogenetic analysis based on 406 single-copy orthologous genes revealed that A. hypochondriacus is most closely linked to A. hybridus and distantly related to A. cruentus. However, dioecious amaranth species, such as A. tuberculatus and A. palmeri, which belong to the subgenera Amaranthus Acnida, have formed their distinct clade. The comparative analysis of genomic data of amaranth species will be useful to identify and characterize agronomically important genes and their mechanisms of action. This will facilitate genomics-based, evolutionary studies, and breeding strategies to design faster, more precise, and predictable crop improvement programs.

Published: March 2024

Mulching practices have been used to improve peach growth and production across the globe. However, the impact of mulching on the physiochemical properties and soil characteristics of orchards remains largely unknown. This study aimed to decipher the impacts of various mulching patterns on the soil environment and the quality of Prunus persica fruit in “Zijinhuangcui”. Three treatments were set up, which included black ground fabric mulch (BF) and two living grass mulch treatments (HV: hairy vetch and RG: ryegrass). The results showed that different mulching treatments have different effects on soil, plant growth, and fruit quality. Living grass mulch treatments, especially the HV treatment, significantly improved soil nutrients by enhancing nitrogen-related indicators. Of note, the BF treatment had higher total phosphorus and available phosphorus contents than the HV and RG treatments. The HV treatment had the highest relative abundance of Proteobacteria (33.49%), which is associated with symbiotic nitrogen fixation, followed by RG (25.62%), and BF (22.38%) at the young fruit stage. Similarly, the abundance of Terrimonas, which has a unique nitrogen fixation system at the genus level, was significantly higher in the living grass mulch (HV, 1.30–3.13% and RG, 2.27–4.24%) than in the BF treatment. Living grass mulch also promoted tree growth, increased fruit sugar content, sugar-related components, and sugar-acid ratio, and reduced the acid content. Collectively, the findings of this study show that living grass mulch can promote tree growth and improve fruit quality by improving soil fertility, bacterial diversity, and richness.
Preaching the Ecclesiological Gospel Amidst a Syndemic Context
Authors: Kim Seyeom
Published: March 2024

As the proliferation of new variations of COVID-19 (Coronavirus Disease 2019) continues to increase, it is evident that the COVID-19 pandemic is not over. Indeed, we are living in a world of interrelating and overlapping pandemics—a syndemic. A syndemic accelerates the polarization of access to health care, financial support, and education opportunities in marginalized communities, and the polarization breeds social injustice, violence, and ignorance. What, then, is the Gospel the Church proclaims for those who have experienced the pandemic and are now facing a syndemic? As part of a liturgical response, this paper proposes preaching as a praxis of the ecclesiological Gospel. The ecclesiological Gospel is a term I suggest to highlight the contextual, sacramental, and communal aspects of the Gospel. Highlighting God’s holistic work for salvation represented in baptism and the eucharist, the ecclesiological Gospel yearns to form a church that baptizes people in diversity, that severs evil interconnections, and that welcomes people to the table of hospitality that forms a new covenantal relationship. This paper examines the concept of a syndemic and its significance for preaching in marginalized communities. It contrasts a holistic Gospel perspective with a narrow view, proposes preaching as praxis of the ecclesiological Gospel, and illustrates its application within a particular context in responding to syndemic conditions. I hope this work offers a chance to reorient the meaning of the Gospel and the identity of the Church for people living in fear, grief, and hopelessness, while encouraging them with the unwavering hope revealed in Christ’s suffering, death, and resurrection.
Assessing Financial Stability in Turbulent Times: A Study of Generalized Autoregressive Conditional Heteroskedasticity-Type Value-at-Risk Model Performance in Thailand’s Transportation Sector during COVID-19
Authors: Likitratcharoen Danai , Suwannamalik Lucksuda
Published: March 2024

The Value-at-Risk (VaR) metric serves as a pivotal tool for quantifying market risk, offering an estimation of potential investment losses. Predominantly employed within financial sectors, it aids in adhering to regulatory mandates and in devising capital reserve strategies. Nonetheless, the predictive precision of VaR models frequently faces scrutiny, particularly during crises and heightened uncertainty phases. Phenomena like volatility clustering impinge on the accuracy of these models. To mitigate such constraints, conditional volatility models are integrated to augment the robustness and adaptability of VaR approaches. This study critically evaluates the efficacy of GARCH-type VaR models within the transportation sector amidst the Thai stock market’s volatility during the COVID-19 pandemic. The dataset encompasses daily price fluctuations in the Transportation Sector index (TRANS), the Service Industry index (SERVICE), and 17 pertinent stocks within the Stock Exchange of Thailand, spanning from 28 December 2018 to 28 December 2023, thereby encapsulating the pandemic era. The employed GARCH-type VaR models include GARCH (1,1) VaR, ARMA (1,1)—GARCH (1,1) VaR, GARCH (1,1)—M VaR, IGARCH (1,1) VaR, EWMA VaR, and csGARCH (1,1) VaR. These are juxtaposed with more traditional, less computationally intensive models like the Historical Simulation VaR and Delta Normal VaR. The backtesting methodologies encompass Kupiec’s POF test, the Independence Test, and Christoffersen’s Interval Forecast test. Intriguingly, the findings reveal that the Historical Simulation VaR model surpasses GARCH-type VaR models in failure rate accuracy. Within the GARCH-type category, the EWMA VaR model exhibited superior failure rate accuracy. The csGARCH (1,1) VaR and EWMA VaR models emerged as notably robust. These findings bear significant implications for managerial decision-making in financial risk management.
Efficient Neural Networks on the Edge with FPGAs by Optimizing an Adaptive Activation Function
Authors: Jiang Yiyue , Vaicaitis Andrius , Dooley John , Leeser Miriam
Published: March 2024

The implementation of neural networks (NNs) on edge devices enables local processing of wireless data, but faces challenges such as high computational complexity and memory requirements when deep neural networks (DNNs) are used. Shallow neural networks customized for specific problems are more efficient, requiring fewer resources and resulting in a lower latency solution. An additional benefit of the smaller network size is that it is suitable for real-time processing on edge devices. The main concern with shallow neural networks is their accuracy performance compared to DNNs. In this paper, we demonstrate that a customized adaptive activation function (AAF) can meet the accuracy of a DNN. We designed an efficient FPGA implementation for a customized segmented spline curve neural network (SSCNN) structure to replace the traditional fixed activation function with an AAF. We compared our SSCNN with different neural network structures such as a real-valued time-delay neural network (RVTDNN), an augmented real-valued time-delay neural network (ARVTDNN), and deep neural networks with different parameters. Our proposed SSCNN implementation uses 40% fewer hardware resources and no block RAMs compared to the DNN with similar accuracy. We experimentally validated this computationally efficient and memory-saving FPGA implementation of the SSCNN for digital predistortion of radio-frequency (RF) power amplifiers using the AMD/Xilinx RFSoC ZCU111. The implemented solution uses less than 3% of the available resources. The solution also enables an increase of the clock frequency to 221.12 MHz, allowing the transmission of wide bandwidth signals.

Published: March 2024

Interferometric radars are widely used for monitoring civil structures. Bridges are critical structures that need to be constantly monitored for the safety of the users. In this work, a frequency-modulated continuous wave (FMCW) multiple-input multiple-output (MIMO) radar was used for monitoring an arched bridge in Catanzaro, Italy. Two measurements were carried out; a first standard measurement was made in a monostatic configuration, while a subsequent measurement was carried out in a multimonostatic configuration in order to retrieve the components of the deck displacement. A method that is able to predict the measurement uncertainty as a function of the multimonostatic geometry is provided, thereby aiming to facilitate the operators in the choice of the proper experimental setup. The multimonostatic measurement revealed a displacement along the horizontal direction that was four times higher than the one along the vertical direction, while the values reported in the literature correspond to a ratio of at most around 0.2. This is the first time that such a large ratio detected by radar has been reported; at any rate, it is compatible with the arched structure of this specific bridge. This case study highlights the importance of techniques that are able to retrieve at least two components of the displacement.

Published: March 2024

Background: The Japanese concept of “ikigai” embodies the feeling of having a meaningful purpose in life. It is associated with several positive outcomes. This study aimed to translate and validate the German version of the Ikigai-9 scale (Ikigai-9-G)—and ikigai scores for certain groups of interest were presented. Methods: Data were taken from a quota sample of the German adult population aged 18 to 74 years (n = 5000; representative in terms of age, sex, and state). Data were collected in August/September 2023. The translation process was conducted in accordance with the existing guidelines. Reliability (Cronbach’s alpha; McDonald’s omega) was assessed. Moreover, we evaluated the structure’s soundness using confirmatory factor analysis for construct validity and examined concurrent validity by exploring pairwise correlations between the Ikigai-9-G with life satisfaction, happiness, health-related quality of life, depressive symptoms, and anxiety symptoms. Additionally, we presented ikigai scores for specific sociodemographic groups of interest. Results: Cronbach’s alpha for the Ikigai-9-G equaled 0.88. The results of confirmatory factor analysis supported the original three-factor model as initially proposed. A higher sense of ikigai was associated with less depressive symptoms (r = −0.43, p < 0.001), less anxiety symptoms (r = −0.39, p < 0.001), higher health-related quality of life (r = 0.42, p < 0.001), higher happiness levels (r = 0.62, p < 0.001), and higher satisfaction with life levels (r = 0.57, p < 0.001). Conclusion: The Ikigai-9 scale is a psychometrically sound tool offering the possibility for assessing ikigai among German speakers. Additional translation and validation studies are required to facilitate comparisons across different countries.

Published: March 2024

Architecture principles affect a software system holistically. Given their alignment with a business strategy, they should be incorporated within the validation process covering aspects of sustainability. However, current research discusses the influence of architecture principles on sustainability in a limited context. Our objective was to introduce a reusable process for monitoring and evaluating the impact of architecture principles on sustainability from a software architecture perspective. We sought to demonstrate the application of such a process in professional practice. A qualitative case study was conducted in the context of a Dutch airport management company. Data collection involved a case analysis and the execution of two rounds of expert interviews. We (i) identified a set of case-related key performance indicators, (ii) utilized commonly accepted measurement tools, and (iii) employed graphical representations in the form of spider charts to monitor the sustainability impacts. The real-world observations were evaluated through a concluding focus group. Our findings indicated that architecture principles were a feasible mechanism with which to address sustainability across all different architecture layers within the enterprise. The experts considered the sustainability analysis valuable in guiding the software architecture process towards sustainability. With the emphasis on principles, we facilitate industry adoption by embedding sustainability in existing mechanisms.

Published: March 2024

Summary: For a mathematical model of mobile wireless computer networks, the random process of alternating network connectivity and disconnection was studied using several mobility models: isotropic random walk with reflection from the boundaries of the network location area, partially directed random walk, random walk with elements of vortex motion. The probability distribution functions of the durations of periods of network connectivity and disconnection are found, the ergodicity of the process and the uncorrelated nature of the period durations are shown. A large positive asymmetry of the distributions was noted, indicating the presence of a relatively small number of periods of long duration in the process. The analysis was carried out using simulation methods. The results of the analysis are presented as dependency plots.

The chemical method of deratisation is the main means of regulating the numbers of synanthropic rodents. Low efficiency of deratisation measures can be related both to resistance of rats and mice to blood anticoagulants and to low attractiveness of baits. Thus, low eatability of baits entails insufficient cumulation of poison and, as a consequence, insufficient toxic effect on the animal organism. This paper describes the results of experiments to study the degree of sensitivity of grey rat individuals to the second generation anticoagulants bromadiolone and brodifacoum, most commonly used in deratisation practice. Sensitivity was determined by direct injection of anticoagulant solutions in neutral solvent into the stomach. The mean lethal concentration calculated by Hill’s equation for a single gastric administration was 0.35 mg/kg for bromadialone and 0.182 mg/kg for brodifacoum. The data obtained can be used in calculating the required amount of bait that must be eaten by the rodent to achieve lethality. Keywords: synanthropic rodents, grey rat, deratisation measures, anticoagulants, bromadiolone, brodifacoum.

The development of business strategies, particularly in the marketing of SMEs, requires the utilization of business intelligence as the foundation for objective decision-making. This research aims to develop a business intelligence scheme for SMEs and design targeted assistance strategies for SME support institutions. The implementation of business intelligence involves leveraging transactional data from SMEs to ascertain customer segmentation and correlating it with Customer Relationship Management (CRM) strategies. Transactional data is processed into a Recency, Frequency, Monetary (RFM) data model. Customer segmentation is achieved through a clustering process using the K-Means algorithm, and the results yield distinct profiles for SME customers. Evaluation processes are conducted to determine the optimal solution for the number of customer segments. Evaluation methods, including the Elbow Method, Silhouette Scores, and Davies–Bouldin Index, are employed to determine the optimum cluster. The evaluation results indicate that the optimum cluster is 3, with the best Silhouette Score being 0.548 and Davies–Bouldin Index at 0.76. The first customer segment exhibits the highest shopping frequency and monetary value, categorizing them as active and profitable customers. Special loyalty services are recommended for this segment. The second segment, despite having the largest number of customers, exhibits a shopping frequency of only 1-2 times, with an average recency of approximately the last 2 months. These customers require effective after-sales service. The third segment consists of customers who last shopped more than 6 months ago, making them a low-priority segment. Re-engagement strategies, such as email marketing, are suggested for this segment. Support institutions can focus on CRM assistance targeting these three identified segments.

The concept of sustainable development, which has been recognized by the UN and all countries of the world over the past 30-40 years, has become the consensus official paradigm of the world economy in the 21st century. The changed paradigm of the global economy, the foundation of which became the "Goals of sustainable development, the climate agenda and ESG – the transition created a new mega trend of the financial industry – “sustainable finance or finance of new quality”. “Green finance” is considered as a strategic direction of sustainable financing.

The purpose of the article is to substantiate theoretical and practical conceptual approaches to the definitions of “green economy” and “green finance” in the new paradigm of the global economy, as well as their use in the sustainable investment development of Ukrainian economy.

Results. Key initiatives in the field of sustainable development, as well as conceptual approaches to the definitions of "green economy" and "green finance" are considered. Focused attention on the concept of sustainable finance, the trend of which foresees a revolutionary approach from the classical paradigm of finance to a new paradigm. Financing instruments and mechanisms, such as green bonds, credits and loans, which are not fundamentally new in technical terms, but contain an ecological component, have been analyzed. It is argued that the concept of sustainable development finance acquires both theoretical justification and practical confirmation in the academic discourse. The NBU strategic approaches to the construction and development of sustainable financing, taking into account ESG factors in the European integration vector of Ukraine were studied.

Conclusions. It is justified that the paradigm of sustainable finance should be considered in an inextricable relationship with the notions of sustainable development and sustainable investment, which is correlated with the achievement of sustainable development goals. In further scientific research, it is necessary to pay special attention to the key principles of the development of sustainable financing in Ukraine, especially the implementation of environmental, social and managerial (ESG) factors, which will become mandatory elements of the corporate management systems of financial institutions.
TAX TRANSPARENCY AS ESSENTIAL PRECONDITION OF THE MODERN TAX PAYMENT ADMINISTRATION SYSTEM

Published: March 2024

Introduction. Modern challenges in the field of administration of tax payments have become especially acute for Ukraine in the conditions of the outflow of human capital and the loss of economic potential. Under such conditions, the role of tax transparency is decisive, because during the implementation of the administration process, it is a necessary prerequisite for the implementation of the basic principles of taxation - fairness and certainty.

The purpose of this article is to determine the place of tax transparency in the tax payment administration system.

Results. The evolutionary aspect of the formation of the definition was studied and the author’s definition of the term “tax transparency” was given. The place of tax transparency in the system of administration of tax payments in the context of the implementation of the administration of tax payments is determined, taking into account potentially possible scenarios of the development of events and actions on the part of taxpayers and tax administrations. The current state of implementation of tax transparency in Ukraine in comparison with other countries is studied. The vector of future necessary transformations of relations between taxpayers and the tax service in Ukraine for the implementation of the strategy of tax transparency is outlined.

Conclusions. The dynamics of the development of international taxation, especially in the modern realities of the development of public finances of Ukraine, requires a rethinking of approaches to the process of implementing tax administration. The study of directions for increasing the efficiency of the administration process is the subject of further scientific research through the implementation of tax transparency, in particular, by building a close relationship and trust between taxpayers and the tax service.
Low-field transport properties and scattering mechanisms of degenerate n-GaN by sputtering from a liquid Ga target
Authors: Döring P. , Tschirky T.
Published: March 2024

In this work, degenerate n-type GaN thin films prepared by co-sputtering from a liquid Ga-target were demonstrated and their low-field scattering mechanisms are described. Extremely high donor concentrations above 3 × 1020 cm−3 at low process temperatures (<800 °C) with specific resistivities below 0.5 mΩcm were achieved. The degenerate nature of the sputtered films was verified via temperature-dependent Hall measurements (300–550 K) revealing negligible change in electron mobility and donor concentration. Scattering at ionized impurities was determined to be the major limiting factor with a minor contribution of polar optical-phonon scattering at high temperatures.

Atención y la prefocalización en la lectura de obras literarias
Authors: Cherñavsky Leandro Javier
Published: March 2024

El presente trabajo critica el rol constitutivo que tanto Gérard Genette como Jean-Marie Schaeffer le otorgan a la atención en la relación estética entre un sujeto y una obra literaria. A su vez, el análisis realizado es útil para resignificar el concepto de prefocalización criteriosa de Noël Carroll. A partir de análisis estructurales y narrativos de la obra de arte literaria, se argumenta que la atención estética no es necesaria en la relación estética. Por otra parte, se defiende que los estados afectivos y estéticos generados por la lectura dependen de la relación entre el lector y ciertos elementos formales existentes en la obra. En concordancia, se propone una interpretación de la prefocalización criteriosa que resalta la importancia de la influencia de las elecciones del autor en la respuesta afectiva del lector.

ABSTRACTThere are many ways to stay healthy and strengthen your immune system during this pandemic, immunity can't be built in a day, but the good news is that a balanced diet and drink and being physically and mentally active is usually enough to keep your immune system in good health. Herbal medicine may be an option to strengthen a person's immune system. Jamu is a traditional Indonesian herbal medicine that has been practiced for centuries in Indonesian society to maintain health and treat disease. Even though there are many modern medicines, herbal medicine is still very popular in rural and urban areas (Elfahmi et al., 2020). The aim of this service is to explain and educate about the role of herbal medicine in improving the body's immune system in facing the transition season in Srikuncoro Village, Central Bengkulu. The methods used were in the form of distributing leaflets, counseling through training about the role of herbal medicine to improve the immune system, as well as counseling and training for 50 people, and the service instrument in the form of distributing questionnaires and measuring with a pre-test to measure the participants' initial knowledge. The target of this community service is the entire community in Srikuncoro Village, Central Bengkulu. The results of the frequency data show that before counseling the results were in the good category of 88.46% for 39 respondents, the medium category for 11.54% for 10 respondents and the poor category for 3.85% for 1 respondent. It was concluded that the pre-test results were 88.46% in the good category with 1 respondent in the poor category and 10 respondents in the medium category. The post-test results were 98.2% with 50 respondents in the good category. And there is a significant influence between knowledge before and after the counseling is 0.02. It is hoped that this counseling and training can be applied by PKK mothers to make and consume traditional concoctions to increase endurance both in the family and in the surrounding environment. Keywords:  The Role of Herbal Medicine; Immune System; Transition Season
