Digital Transformation in Public Administration and Data-Driven Decision-Making: A Review of Turkana County Government
Authors: Onunga Jeremiah , Odongo Paul
Published: January 2025

Digital transformation is increasingly becoming a focal point for organizations and governments worldwide, including Kenya. In Kenya, the 2010 Constitution introduced devolution, decentralizing governance, enabling county-level implementation of government programs, and extending governance to the grassroots. Among the functions devolved to counties is Early Childhood Development and Education (Pre-primary education), aimed at enhancing efficiency, transparency, and accountability in governance. Turkana County, inhabited primarily by the Turkana people with a history of nomadic pastoralism, views Pre-primary education as crucial for initiating academic life. Embracing digital transformation in Pre-primary education implementation represents a significant shift. The study focused on Turkana County Government’s strategies for digital transformation in Pre-primary education and identified key objectives: Assessing digital inclusion in public administration in Turkana County; recommending practical implementation of two systems: Turkana Early Childhood Development Education Management Information System and Continuous Database Updating system; and establishing sustainability measures for data-driven decision-making. The study employed a descriptive research design involving observation and desktop review of county online platforms and libraries. Information gathered affirmed the status of digital transformation in Pre-primary education and guided recommendations. Turkana County Government has implemented two digital systems: Turkana Early Childhood Development and Education Management Information System (a website) and Continuous Database Updating System (Data entry and updating system). The website hosts programs and data related to pre-primary education management, including teacher and learner information, infrastructure development, feeding programs, policy updates, and reports on supervision and evaluation of teachers. Recommendations for successful digital transformation included investing in community engagement for program sustainability, strengthening administrative structures, and enhancing digital technology in Pre-primary education. These measures aim to ensure efficient and effective management of Pre-primary education programs. In conclusion, the Turkana County Government’s adoption of the two digital systems marks a significant step towards modernizing Pre-primary education management. By following the study’s recommendations, Turkana County can achieve enhanced governance and educational outcomes through digital transformation, thereby serving as a model for similar initiatives across Kenya’s counties.

Ferric Carboxymaltose (Ferinject)
Authors: CDA-AMC
Published: January 2025

The Canada’s Drug Agency (CDA-AMC) Canadian Drug Expert Committee (CDEC) recommends that public drug programs reimburse Ferinject for the treatment of iron deficiency anemia if certain conditions are met.
Ferinject should only be covered to treat patients with iron deficiency anemia who are aged 1 year or older when oral iron preparations are not tolerated or are ineffective according to the reimbursement criteria used for IV iron formulations that are currently reimbursed by public drug plans. CDEC noted that patients with underlying risk factors for hypophosphatemia may require monitoring of serum phosphate if they require multiple doses of ferric carboxymaltose for long-term treatment.
Ferinject should only be reimbursed if it is prescribed by a clinician with expertise in managing iron deficiency anemia in adult and pediatric patients aged 1 year and older and the cost of Ferinject is reduced.

Analisis Pengaruh Desain Kumparan 6-Fasa Terhadap Torsi Dan Kecepatan Motor Induksi 3-Fasa Berbasis Desain 3 Fasa Ganda Tak Simetris
Authors: Zuriman Anthony  , Ica Laras Widia  , Erhaneli Erhaneli  , Arfita Yuana Dewi Putra  , Andi Syofian
Published: January 2025

This study aims to examine the impact of a 6-phase design using an asymmetrical dual
3-phase design on the torque and speed of an induction motor, where the newly designed motor still uses a 3-phase power source. The research compares the performance of a conventional 3-phase induction motor with that of an asymmetrical 6-phase induction motor design, focusing on torque and speed. This motor is only designed in terms of its windings, so the motor's position remains unchanged. The 3-phase system applied to the 6-phase induction motor design ensures that the 6-phase motor operates within a 3-phase system. The study also explores performance improvements, particularly in torque and speed, by redesigning the windings of a 3-phase induction motor into an asymmetrical 6-phase motor.
The induction motor used in this research has the following specifications: 3-phase, 2 A, 1390 RPM, 50Hz, 0.75 kW, and 380Y. The study aims to understand the effects of the asymmetrical 6-phase induction motor design, particularly regarding torque and speed. The results show that the torque and speed of the two motors differ due to the asymmetrical 6-phase winding design. In a conventional 3-phase induction motor, the winding coil layer distance is 120°, whereas, in the asymmetrical 6-phase induction motor, the distance between the first and second layers is 30°. Based on this analysis, the asymmetrical 6-phase induction motor design demonstrates better performance compared to the conventional 3-phase induction motor.

Authors: Putu Bagus Adidyana Anugrah Putra  , Septian Geges  , Oktaviani Enjela Putri  , I Made Bayu Artha Pratama
Published: January 2025

Hydroponic plant cultivation is booming, but stock and sales are hard to predict. Poor prediction can cause farmers to overstock and lose money. This study suggests a framework that uses several machine learning models, including Linear Regression (LR), Random Forest (RF), Decision Tree (DT), and Extreme Gradient Boosting. "Ensemble Learning," which combines these models, should yield more accurate and generalizable results than a single model. This framework is assessed using historical hydroponic plant sales data and related factors like price, weather, and market trends. The model's performance is measured by the difference between predictions and actual values using RMSE and MAE metrics. This framework should improve hydroponic plant stock and sales predictions. Farmers can make better production, inventory, and harvest distribution decisions. Besides reducing financial losses, this reduces food waste and improves food security.

Programação metabólica associados ao baixo peso nascer e aos níveis do Hormônio do Crescimento e Fator de Crescimento Relacionado à Insulina: Uma revisão narrativa
Authors: PESSOA MACIEL DINIZ LUCIANA , FERRO CAVALCANTE TAISY CINTHIA , ALVES MARCELINO DA SILVA AMANDA
Published: January 2025

As doenças crônicas não-transmissíveis se referem ao conjunto de patologias de diferentes naturezas clínicas com denominador comum que são alterações metabólicas. O ambiente fetal é um período crítico ao desenvolvimento do indivíduo aumentando o risco de doenças metabólicas na vida adulta. O baixo peso ao nascer é resultado da restrição  nutricional, que pode ocasionar um crescimento rápido intrauterino, aumentando o risco de erros ou imprinting.   Uma teoria para compreender os processos que levam ao imprinting, com consequências metabólicas futuras, é a teoria epigenética.  Trata-se de um conjunto de fatores hereditários que modificam a expressão gênica sem alterar a sequência primária da fita de DNA. Os principais mecanismos epigenéticos são descritos como: metilação de DNA, modificações de histonas e os Micro – RNA. A metilação do DNA, como resultado silencia genes promotores celulares. As histonas, que são proteínas responsáveis pelo primeiro nível de compactação do DNA, podem ser metiladas ou acetiladas, o que pode modificar a expressão gênica. Os Micro - RNA, por fim, são RNAs não codificantes que exercem a função regulatória na expressão gênica transcricional e pós-transcricional.  O eixo hormônio do crescimento / fator de crescimento relacionado a insulina tipo 1, que exerce papel central na homeostase do catabolismo-anabolismo, pode sofrer alterações induzidas pela restrição nutricional que repercutem na ação desses hormônios, ocasionando alterações metabólicas complexas que podem estar associadas a doenças na vida adulta. Como estratégia para minimizar o risco do baixo peso temos a prevenção através do pré-natal e orientação nutricional da gestante e até a primeira infância.

ANALIZA ALTERNATIVNIH ELEKTROENERGETSKIH KONCEPTOV ZA SLOVENIJO Z VIDIKA TRAJNOSTNEGA RAZVOJA
Authors: P. Damijan Jože , Babič Drago
Published: January 2025

Povzetek. Članek prinaša dva glavna izvirna prispevka. Prvi prispevek
je kvantitativna opredelitev potrebnega obsega električne energije za potrebe razvojne dinamike, s katero bi Slovenija do leta 2050 dosegla sedanjo raven razvitih držav EU, in za potrebe energetskega prehoda. Analiza
kaže, da naj bi se skupna poraba električne energije med letoma 2025 in
2050 zaradi zagotavljanja ustrezne ravni blaginje in zaradi energetskega
prehoda podvojila. Drugi prispevek članka je v opredelitvi optimalnega
elektroenergetskega sistema Slovenije, ki bi hkrati zagotovil realizacijo
obeh ciljev in zadostil ključnim kriterijem. V članku primernost treh alternativnih elektroenergetskih sistemov (NEPN OVE, NEPN OVE + jedrska,
SAZU-GZS) presojamo iz petih vidikov. Ugotavljamo, da je koncept SAZU-GZS superioren po vseh petih kriterijih, in sicer glede (1) zadostnega
obsega električne energije, (2) strateške avtonomije Slovenije pri električni
energiji, (3) za polovico nižjih potrebnih investicij na enoto proizvedene
električne energije, (4) za polovico nižje stroškovne cene električne energije, (5) razogljičenja proizvodnje in porabe električne energije v Sloveniji.
Na podlagi tega ugotavljamo, da je za potrebe trajnostnega razvoja pomembna prava kombinacija nizkoogljičnih virov (primarno jedrska in
hidro energija ter dopolnilno OVE viri sonca in vetra) in hranilnikov energije, medtem ko so energetski koncepti zgolj na osnovi OVE virov tehnično
nevzdržni in/ali zahtevajo bistveno višje investicije, hkrati pa ne vodijo k
realizaciji podnebnih ciljev glede razogljičenja. Te ugotovitve so v skladu z
ugotovitvami v literaturi s tega področja.
Ključni pojmi: blaginja, trajnostna rast, nizkoogljični viri energije.
SYNTHESISING RESEARCH FINDINGS – METHODOLOGICAL GUIDELINES FOR CONDUCTING THE CRITICAL INTERPRETIVE SYNTHESIS METHOD
Authors: Višić Maroje , Balenović Antonija , Mesarić Jasna
Published: January 2025

Abstract. Critical interpretive synthesis (CIS) integrates prior research into a theoretical framework to generate new hypotheses, theories, models and typologies. It encompasses both quantitative and qualitative data across various disciplines using a critical, reflexive, recursive and dynamic review approach. CIS favours lines of argument for synthesis and acknowledges authorial voices. Nonetheless, it faces criticism for lacking transparency and systematicity. To address these issues, we propose guidelines to enhance transparency and systematicity throughout the process. The article holds implications for research methodology.
Keywords: critical interpretive synthesis, synthetic argument, authorial voice, lines of argument, research methods, systematicity, transparency.

Povzetek. Članek gradi na tezi, da je način produkcije življenja ljudi ključ do razumevanja razmerja med pravom in politiko. Kapitalizem poganja logika koncentracije kapitala, ki je mogoča samo ob nenehnem procesu privatizacije, tj. pretvorbe vseh oposamljivih stvari v zasebno last. Avtor to linijo argumentacije gradi na predstavitvi idej od Akvinskega do Locka in Smitha. Akvinski že zaznava moč meščanske politike in nastajajočega načina produkcije, ki z Morom dobi poskus alternative v vzpostavljanju skupnega lastništva, z Lockom in Smithom pa se idejno zapre zmago kapitalizma v koncepte, ki so vladajoči še danes. Pravo in politika sta v službi pohitrene koncentracije kapitala in v skladu s tem razvijata rešitve, ki ustrezajo reprodukciji tega svetovnega sistema.

Identifying weather patterns responsible for renewable energy droughts over India
Authors: Dijkstra Isa , Bloomfield Hannah C. , Hunt Kieran M. R.
Published: January 2025

Abstract. Energy systems across the globe are evolving to meet climate mitigation targets. This requires rapid reductions in fossil fuel consumption and significant uptake of renewable generation. Renewable energy sources are weather-dependent, causing production to vary at timescales from minutes to decades ahead. A consequence of this variability is that there will be periods of low renewable energy production, here termed renewable energy droughts. This energy security challenge needs to be addressed to ensure grid stability. India is chosen as a study area as it is a region that has both a large proportion of renewable generation and good subseasonal predictability. In this study, we use synthetic wind and solar photovoltaic production timeseries, previously derived for the Indian energy grid using ERA5 reanalysis from 1979–2022, to identify historical renewable energy droughts. These are defined as periods where wind and solar potential is in the lowest 2.5 % compared to climatology. These events commonly occur from November–February, with the longest historical event being 9 d long. We identify the weather regimes that cause the largest renewable energy droughts over India and investigate potential sources of predictability. Existing large-scale daily weather types and impact-based patterns are used to investigate the different weather patterns causing renewable energy droughts. Renewable energy droughts are caused by low seasonal wind speeds in combination with weather patterns bringing high cloud cover. These are mainly weak northeast monsoon and western disturbances. Sources of potential subseasonal predictability are considered for the largest renewable energy droughts, including the Madden Julian Oscillation and Boreal Summer Intraseasonal Oscillation. Although both have a stronger relationship with high energy potential days, links between phases of these two oscillations and renewable energy drought days are identified. These could help to provide early warnings for challenging security of supply conditions in the future.
Ground-based contrail observations: comparisons with reanalysis weather data and contrail model simulations
Authors: Low Jade , Teoh Roger , Ponsonby Joel , Gryspeerdt Edward , Shapiro Marc , Stettler Marc E. J.
Published: January 2025

Abstract. Observations of contrails are vital for improving our understanding of the contrail formation and life cycle, informing models, and assessing mitigation strategies. Here, we developed a methodology that utilises ground-based cameras for tracking and analysing young contrails (< 35 min) formed under clear-sky conditions, comparing these observations against reanalysis meteorology and simulations from the contrail cirrus prediction model (CoCiP) with actual flight trajectories. Our observations consist of 14 h of video footage recorded over 5 different days in Central London, capturing 1582 flight waypoints from 281 flights. The simulation correctly predicted contrail formation and absence for around 75 % of these waypoints, with incorrect contrail predictions occurring at warmer temperatures than those with true-positive predictions (7.8 K vs. 12.8 K below the Schmidt–Appleman criterion threshold temperature). When evaluating contrails with observed lifetimes of at least 2 min, the simulation's correct prediction rate for contrail formation increases to over 85 %. Among all waypoints with contrail observations, 78 % of short-lived contrails (observed lifetimes < 2 min) formed under ice-subsaturated conditions, whereas 75 % of persistent contrails (observed lifetimes > 10 min) formed under ice-supersaturated conditions. On average, the simulated contrail geometric width was around 100 m smaller than the observed (visible) width over its observed lifetime, with the mean underestimation reaching up to 280 m within the first 5 min. Discrepancies between the observed and simulated contrail formation, lifetime, and width can be associated with uncertainties in reanalysis meteorology due to known model limitations and sub-grid-scale variabilities, contrail model simplifications, uncertainties in aircraft performance estimates, and observational challenges, among other possible factors. Overall, this study demonstrates the potential of ground-based cameras to create essential observational and benchmark datasets for validating and improving existing weather and contrail models.

Abstract. Global Navigation Satellite System (GNSS) radio occultation (RO) is a space-based remote sensing technique that measures the bending angle of GNSS signals as they traverse the Earth's atmosphere. Profiles of the microwave index of refraction can be calculated from the bending angles. High accuracy, long-term stability, and all-weather capability make this technique attractive to meteorologists and climatologists. Meteorologists routinely assimilate RO observations into numerical weather models. RO-based climatologies, however, are complicated to construct as their sampling densities are highly non-uniform and too sparse to resolve synoptic variability in the atmosphere. In this work, we investigate the potential of machine learning (ML) to construct RO climatologies and compare the results of an ML construction with Bayesian interpolation (BI), a state-of-the-art method to generate maps of RO products. We develop a feed-forward neural network applied to Constellation Observing System for Meteorology, Ionosphere, and Climate-2 (COSMIC-2) RO observations and evaluate the performance of BI and ML by analysis of residuals when applied to test data. We also simulate data taken from the atmospheric analyses produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) in order to test the resolving power of BI and ML. Atmospheric temperature, pressure, and water vapor are used to calculate microwave refractivity at 2, 3, 5, 8, 15, and 20 km in geopotential height, with each level representing a different dynamical regime of the atmosphere. The simulated data are the values of microwave refractivity produced by ECMWF at the geolocations of the COSMIC-2 RO constellation, which fall equatorward of 46° in latitude. The maps of refractivity produced using the neural networks better match the true maps produced by ECMWF than maps using BI. The best results are obtained when fusing BI and ML, specifically when applying ML to the post-fit residuals of BI. At the six iso-heights, we obtain post-fit residuals of 10.9, 9.1, 5.3, 1.6, 0.6, and 0.3 N units for BI and 8.7, 6.6, 3.6, 1.1, 0.3, and 0.2 N units for the fused BI&ML. These results are independent of season. The BI&ML method improves the effective horizontal resolution of the posterior longitude–latitude refractivity maps. By projecting the original and the inferred maps at 2 km in iso-height onto spherical harmonics, we find that the BI-only technique can resolve refractivity in the horizontal up to spherical harmonic degree 8, while BI&ML can resolve maps of refractivity using the same input data up to spherical harmonic degree 14.

Abstract. This study investigates the relationship between oxygen isotope ratios (δ18O) in oak tree ring cellulose and past drought variability in Letea Forest, Romania. A δ18O site chronology spanning 1803–2020 was compiled from seven individual time series. δ18O values exhibited a significant negative correlation with moisture-related variables (cloud cover, relative humidity, and precipitation) and a positive correlation with temperature and sunshine duration. This confirms that δ18O from tree rings can be a good proxy for moisture availability. The strongest correlation was found between δ18O and the August Standardized Precipitation Evapotranspiration Index for an accumulation period of 9 months (SPEI9) for central and eastern Europe. This highlights SPEI9 as a superior indicator of drought compared to individual parameters like temperature or precipitation. Using a linear regression model, we reconstructed August SPEI9 variability for the past 200 years. The reconstruction captured interannual and decadal variations, with distinct wet and dry periods. Analysis of large-scale atmospheric circulation patterns revealed a link between high δ18O values (indicating dry conditions) and a high-pressure system over the North Atlantic. Conversely, low δ18O values (indicating wet conditions) corresponded to negative pressure anomalies over Europe. Moreover, extreme values of δ18O are also associated with the prevalence of a hemispheric teleconnection pattern, namely wave number 4. This δ18O chronology and the corresponding August SPEI9 reconstruction offer valuable tools for understanding past climate variability and its relationship with large-scale atmospheric and oceanic circulation patterns.

Abstract. Aviation is an important source of urban air pollution, but the impacts of photochemical processing on the exhaust emissions remain insufficiently characterized. Here, the physical-chemical properties of fresh and photochemically aged emissions from a laboratory-scale jet engine burner operated with JP-8 kerosene were studied in detail with a range of online and offline methods. The fresh emissions contained high amounts of organic matter present predominantly in the gaseous phase. Photochemical aging in an oxidation flow reactor caused substantial formation of oxidized organic aerosol, increasing the particle mass by approximately 300 times. During aging, aromatic hydrocarbons and alkanes in the gas-phase decayed, while gas-phase oxidation products, such as small carbonyls and oxygenated aromatics increased. The composition of organic matter became more complex by photochemical processing, with oxidation state increasingly growing throughout the addressed exposure range (equivalent to 0.2 to 7 days in atmosphere) with a ΔH:C/ΔO:C slope of -0.54. Simultaneously, the near-UV wavelength absorption by the particles increased due to enhanced particulate mass. The imaginary refractory indices of organic particulate matter were 0.0071 and 0.00013 at the wavelength of 520 nm for the fresh and photochemically processed particles, respectively, indicating secondary production of weakly absorbing brown carbon. The direct radiative forcing by the exhaust particles was estimated by a Mie-model, which revealed a prominent shift from warming to cooling climate effect upon photochemical aging. The results highlight the importance in considering secondary aerosol formation when assessing the environmental impacts of aviation.

Abstract. Dissolution-precipitation creep (DPC) is considered as one of the main processes accommodating localized strain in polymineralic shear zones of the Earth’s crust. Extensive field evidence for DPC in natural shear zones supports the importance of this process. The spatio-temporal evolution and the level of compositional heterogeneity that facilitate the nucleation of such polymineralic shear zones remain poorly understood. A series of new experiments was conducted on a granitoid fine-grained ultramylonite to different strains at 650 °C, 1.2 GPa with strain rates varying from 10-3 s-1 to 10-6 s-1. In Type I experiments, a fracture was induced (prior to reaching the P,T-conditions), whereas in Type II experiments, no initial fracture was induced. Consequently, in the Type I experiments viscous deformation localized strictly within the previous fracture in a ~20 µm wide zone, with grain sizes being reduced to 150–10 nm. In the Type II experiments, viscous deformation was distributed in the sample, with grain size being reduced locally to 200–50 nm. This study supports two different hypotheses for shear zone nucleation in nature. In brittle induced strain localization, DPC will be activated and lead to a rapid and strong strain localization, producing a very weak and fast deforming high strain zone. In viscously induced strain localization (without main fracture), deformation concentrates along classical strain gradients, requiring higher shear strains to reach mechanical and microstructural steady state at slower deformation rates compared to brittle-induced strain localization. In both end-member strain localization scenarios, the dominant viscous deformation mechanism in the shear zones is grain boundary sliding combined with pinning-assisted DPC. Our experiments indicate that chemical potentials in the microstructures in combination with different strain localization types may explain the often-observed concentration of strain in fine-grained polymineralic mylonites such as in granitoids but also other polymineralic rocks (e.g. peridotites, granulites etc.) in nature.

Abstract. Global hydrological models are one of the key tools that can help meet the needs of stakeholders and policy makers when water management strategies and policies are developed. The primary objective of this paper is therefore to establish a first-of-its-kind, truly global hyper-resolution hydrological model that spans a multiple-decade period (1985–2019). To achieve this, two key limitations are addressed, namely the lack of high-resolution meteorological data and insufficient representation of lateral movement of snow and ice. Thus, a novel meteorological downscaling procedure that better incorporates fine-scale topographic climate drivers is incorporated, and a snow module capable of lateral movement of frozen water resembling glaciers, avalanches, and wind movement is included. We compare this global 30 arcsec version of PCR-GLOBWB (PCR – Global Water Balance) to previously published 5 and 30 arcmin versions by evaluating simulated river discharge, snow cover, soil moisture, land surface evaporation, and total water storage against observations. We show that hyper-resolution provides a more accurate simulation of river discharge, in particular for smaller catchments. We highlight that global hyper-resolution modeling is possible with current computational resources and that hyper-resolution modeling results in more realistic representations of the hydrological cycle. However, our results also suggest that global hydrological modeling still needs to incorporate land cover heterogeneity and relevant hydrological processes at the sub-kilometer scale to provide more accurate estimates of soil moisture and evaporation fluxes.

Abstract. The large-scale landslide susceptibility assessment (LSA) is an important tool for reducing landslide risk through the application of resulting maps in spatial and urban planning. The existing literature more often deals with LSA modelling techniques, and the scientific research very rarely focuses on acquiring relevant thematic and landslide data, necessary to achieve reliable results. Therefore, the paper focuses on the crucial step of classifying continuous landslide conditioning factors for susceptibility modelling by presenting an innovative comprehensive analysis that resulted in 54 landslide susceptibility models to test 11 classification criteria (scenarios which vary from stretched values, partially stretched classes, heuristic approach, classification based on studentized contrast and landslide presence, and commonly used classification criteria, such as natural neighbour, quantiles and geometrical intervals) in combination with 5 statistical methods. The large-scale landslide susceptibility models were derived for small and shallow landslides in the pilot area (21 km2) located in the City of Zagreb (Croatia), which occur mainly in soils and soft rocks. Some of the novelties in LSA are the following: scenarios using stretched landslide conditioning factor values or classification with more than 10 classes prove more reliable; certain statistical methods are more sensitive to the landslide conditioning factor classification criteria than others; all the tested machine learning methods give the best landslide susceptibility model performance using continuous stretched landslide conditioning factors derived from high-resolution input data. The research highlights the importance of qualitative assessments, alongside commonly used quantitative metrics, to verify spatial accuracy and to test the applicability of derived landslide susceptibility maps for spatial planning purposes.
Fractal analysis of geomagnetic data to decipher pre-earthquake processes in the Andaman–Nicobar region, India
Authors: Prajapati Rahul , Arora Kusumita
Published: January 2025

Abstract. Seismo-electromagnetic (SEM) signatures recorded in geomagnetic data prior to an earthquake have the potential to reveal pre-earthquake processes in focal zones. The present study analyses the vertical component of geomagnetic field data from March 2019 to April 2020 using fractal and multifractal approaches to identify the EM signatures in Campbell Bay (CBY), a seismically active region of Andaman and Nicobar. The significant enhancements in monofractal dimension and spectrum width components of multifractal analysis arise due to superpositioned high- and low-frequency SEM field emitted by the pre-earthquake processes. It is observed that the higher-frequency components associated with microfracturing dominating signatures of earthquakes occurring around the West Andaman Fault (WAF) and Andaman Trench (AT), while the lower frequencies, which result from slower electrokinetic mechanisms, have some correlation with the earthquakes around the Seulimeum strand (SS). Thus, the monofractal, spectrum width, and Hölder exponent parameters reveal a different nature of pre-earthquake processes that can be identified, on average, 10, 12, and 20 d prior to the moderate earthquakes, which holds promise for short-term earthquake prediction.
