Authors: Zećo Mirsada , Videnović Marina , Žmukić Maja
Published: December 2023

The authors were engaged in creating activities for workshops in which sound improvisation was combined with artistic expression and introduced to a student-level classroom. The aim of this research is two-fold. The first aim was to examine how students experienced this type of work through workshops. The second was the analysis of students’ drawings following the sound improvisation performance. The workshops were attended by 135 students, aged 19 to 24, from three different faculties. The main research question was if art content can, through sound improvisation and image, significantly awaken positive emotions in students by means of two different mediums. Internalising and developing a positive self-image in students show that there is a correlation between the content of music and art, as well as their influence on the intensity of aesthetic experience. The results showed that the students felt relaxed during the workshop and that they were willing to once again participate in a similar activity. Additionally, the drawings they produced during the workshop were analysed. As a conclusion, it is desirable to integrate content in music and art classes as its aim is to intensify experience, process of development and creation of a safe and positive learning environment. This explorative research showed that it is essential to work on developing experiences of social and emotional content through sound and image, as well as mutual connection strategies of learning and emotionally-aesthetic expression. Key words: sound improvisation, drawing, artistic speech, intensity of feelings

Authors: Chandel Divyank Singh , Pandey Vijaykant
Published: December 2023

Abstract: Heat exchanger that heats up to two or more processing fluids. Heat exchangers have a range of domestic and commercial applications. Use in steam plants, manufacturing plants, heat and air conditioning facilities, transportation, and cooling systems. Through analysis, Ordinarily, the presence of Cu+Al2O3 nanoparticles in the base fluid increases the properties of convective heat transfer and is thus more efficient than Al2O3 nanoparticles (at a steady concentration of volume). The findings revealed that the average heat transfer coefficient increases in line with the Reynolds number. Analysis has shown that the average thermal transfer coefficient value for hybrid nanofluid is 12 percent greater than the average for a single nanofluid. In the case of hybrid nanofluid compared to Mono nanofluid, the value of Nusselt is 18 per cent higher.
CIP Leadership Concept, Analysis on Domestic and Overseas Research a nd E xploring F uture Research Objectives
Authors:   Korean Academy of Leadership, Jung Han Yong , Jeon Ki Seok
Published: December 2023

The purpose of this study is to examine the domestic research trends on the CIP leadership model, explain the concept, and to suggest future research directions. The starting point of the CIP leadership model is a study by Mumford & Van Doorn (2001) on the American historical leader, politician Benjamin Franklin. Mumford (2006) then compared the pathways to outstanding leadership on several important dimensions, and then classified them into three: ‘charismatic leaders’, ‘ideological leaders’, and ‘pragmatic leaders’. Mumford presented the results of classifying 120 historically prominent leaders into six types (20 each), such as [charismatic, ideological, and pragmatic leaders] × [socialized and individualized orientation], using an historiometry method. After the CIP model was introduced to the academic field, research papers are continuously being published in famous overseas journals. However, there are only four papers related to the CIP leadership model in Korea so far, and none of the four papers deal with the CIP model in detail. We look at domestic research trends, introduce the CIP leadership model in detail, and suggest the limitations of the model and future research directions. Through this, it is hoped that the interest of Korea leadership researchers in the CIP leadership model can be enhanced and the leadership research method can be expanded.

Published: December 2023

Objective: To study the significance of Depth of invasion (DOI), and the degree of differentiation (DOD) as predictors of cervical nodalmetastasis in oral squamous cell carcinoma. To determine a cut-off depth beyond which there is a high risk of cervical metastasis. Todetermine whether the DOI can be is alone enough as predictor for lymphatic metastasis despite the DOD.
Methods: Forty-eight patients with OSCC were included in the study 28 males and 20 females ranging between 25 to 80 years. Alltreated in Ghazi Al-Hariri hospital for surgical specialties in Baghdad Medical city between 2017 to 2019. Slides were examined afterimmunohistochemical staining. Depth of invasion was measured according to the criteria of AJCC, and the WHO system of grading was, all histopathological parameters were recorded after immunohistochemical staining.
Results: The depth of invasion ranged between 2 and 13 mm with a mean of 6.58 mm and SD of ± 2.56 mm and it was found to be ahighly significant predictor for lymphatic metastasis (P-value = 0.001), the cut-off point with a significant risk of metastasis was 5 mm. Thedegree of differentiation was also a significant predictor for cervical metastasis (P-value = 0.024) with poorly differentiated SCC carrying the highest risk of cervical metastasis despite the depth of the tumor invasion.
Conclusion: DOI and DOD were significant histological parameters that predict the behavior of the well and moderately differentiated oral squamous cell carcinoma and hence the management of the neck in OSCC. However, the depth of invasion was not significance in cases of poorly differentiated OSCC. Therefore, we recommend that elective neck dissection should be done in cases of poorly differentiated OSCC despite the DOI.

Authors: Haidar Salman Maha , Mujahid Al-Shuwaikh Arwa
Published: December 2023

Background: In 1997, Torque Teno virus (TTV) discovered for the first time in Japanese patients who suffer from hepatitis. Then, it is detected in healthy individuals without causing harmful effects. Also, it is a part of our microbiome, with a high rate in all populations. This virus belong to a large viral family called Anelloviridae. Today, there are many suggestions to use TTV as a novel biomarker for medical and environmental purposes.

Objective: To determine the rate of TTV infection in Iraqi blood donors. And evaluate any association with demographic and risk factors.

Methods: This cross-sectional study conducted on serum samples from 359 participants who attended the blood donation unit of Al-Imammain Al-Kadhimain Medical City Hospital and National Blood Transfusion Center in Baghdad. The study sample consists of 351  males and only 8 females; their mean age is (36.04 ± 9.35 SD). For a period from  November 2022 to January 2023. A nested polymerase chain reaction (PCR) was used to detect TTV untranslated region.

Results: The TTV virus was detected in 93.9% (337 out of 359) of blood donors. However, no significant association was found between demographic data (sex, age) and risk factors such as history of (medical surgery, tattooing, cupping practice, marital status, multiple sexual partners,  animal husbandry , travel history), under line medical condition (diabetes mellitus and  hypertension), viral hepatitis co-infection  and occupation with TTV infection rate.

Conclusion: This study showed a high prevalence of TTV among healthy blood donors with no significant association with demographic data and risk factors. These results support that TTV as a part of the human virobiome and normally found in the majority of  populations.

Published: December 2023

Introduction: Iron deficiency anemia is the most common cause of anemia worldwide, and increased iron requirement during pregnancy increases the risk of anemia. Anemia in pregnancy is associated with adverse pregnancy outcomes such as low birth weight, preterm and intrauterine growth restriction. This study used a Rule-based Intelligent Classification Models to predict socio-demographic, nutritional, antenatal care and obstetric factors on iron deficiency anemia during pregnancy
Methods: This retrospective study was a secondary analysis of a community-based cross-sectional study conducted between January and June 2019 in the province of Elazig in eastern Turkey. Data of 495 pregnant women were included in the study iron deficiency anemia was defined as hemoglobin  < 11 g/dl, and ferritin < 30 µg/L. Rule-based machine learning methods were used to predict factors associated with anemia during pregnancy.
Results: The mean age of 495 pregnant women were 30.06 ± 5.15 years. The prevalence of anemia was 27.9% in study population. Maternal age, educational status, occupation, nutrition education status, nutritional property, gravida, and parity were significantly related to anemia. Jrip, OneR, and PART algorithms estimated factors associated with anemia with 96.36%, 85.45%, and 97.98% accuracy, respectively.
Conclusion: Rule-based machine learning algorithm may offer a new approach to risk factors for iron deficiency anemia during pregnancy. With the use of this model, it is possible to predict the risk of anemia both before and during pregnancy and to take preventative measures.

Authors:   Smolensk State University, ROZANOVA N.N.
Published: December 2023

The purpose of the research in presenting its results within the framework of this article is to determine the peculiarities of the content of the reputation of the Russian power in the regions of the Russian Federation, taking into account the national and religious factors of its formation. The object of the study is the Russian political space on the axis of interaction "power – society". Subject – the reputation of large-scale institutional subjects - Russian power in general (state and municipal power of the Russian Federation - public power) and various levels and branches of power (by the example of the reputation of the state executive power of the subject of the Russian Federation). The results of a sociological study of the population opinion of 10 regions are presented. National and religious factors of reputation formation are interpreted based on the degree of predominance of single- or multi-ethnic composition of the region and one of the two most widespread religions practiced in Russia: Orthodoxy or Islam. The fundamental unity in the "filling" of the content of the reputation of the Russian power in the presence of regional peculiarities in the part of setting slightly different priorities in the choice of reputational characteristics is determined; no direct dependence on the studied factors is revealed.
SOCIAL AND ECONOMIC DEVELOPMENT OF RUSSIA. UPS AND DOWNS. OPPORTUNITIES AND PROSPECTS
Authors:   Russian Academy of Sciences, AGANBEGYAN A.G.
Published: December 2023

At the beginning the outstanding achievements of the USSR in solving the atomic problem, space exploration, development of education and life extension, which the new Russia inherited, are examined. After the catastrophic deterioration of socio-economic and demographic indicators during the transformation crisis in the new Russia (1991-1998), there was a recovery and the implementation of national programs “Demography” and “Health” which greatly improved our indicators and overcame depopulation. The greatest attention is paid to the last period starting with the crisis of 2009, the post-crisis increase and seven years of stagnation. Then in 2020-2021 the coronavirus pandemic followed, greatly increasing the mortality rate of the population, and later there was the holding of the SWO in Ukraine (2022-2023). The economy and social indicators were stagnant during this period. But we managed to eliminate the record high mortality rate. A large section is about perspectives, where concrete examples of regions, industries, and best enterprises show world-class socio-economic achievements that need to be disseminated. Conclusion: Russia is a country of great opportunities, capable of conquering high peaks.
Elementos para uma reflexão sobre o jornalismo declaratório
Authors: Araújo Arthur Silva
Published: December 2023

Este artigo parte de uma percepção da ausência de reflexão teórica sobre o que seria o fenômeno usualmente denominado de jornalismo declaratório e seu posicionamento enquanto categoria dos estudos de jornalismo. O trabalho pretende, portando, realizar uma proposta de reflexão sobre a prática baseada em cinco dimensões: visibilidade e circulação, tensionamento da declaração, notoriedade da fonte, relevância do tema e percepção de nocividade da declaração para o debate público. Propõe-se, ainda, a manutenção da categoria enquanto parte da crítica às práticas jornalísticas, rejeitando seu enquadramento como especialidade do jornalismo ou como tipologia textual. O trabalho traz revisão bibliográfica sobre o tema e utiliza exemplos de produção noticiosa para sustentar sua argumentação, seguindo proposta de “inversão metodológica” semelhante a Silva (2013).
Representações da educação no jogo digital Pokémon Scarlet
Authors: Lopes Albuquerque Bastos Lucas , Farbiarz Alexandre
Published: December 2023

Os sujeitos na contemporaneidade recebem crescente influência das mídias em suas negociações de sentidos sobre a realidade social, contexto esse no qual jogos digitais se inserem. Entre as esferas culturais e políticas sobre as quais os jogos estabelecem retóricas encontra-se a educação. O problema de pesquisa é como a educação é representada, enquanto valor cultural e político, no game Pokémon Scarlet. Pretendemos analisar diálogos entre essas representações e perspectivas de letramento midiático crítico. Como metodologia, combinamos a abordagem dos Valores em Jogos Digitais, de Mary Flanagan e Helen Nissenbaum, e os esquemas de análise de jogos de Clara Fernández-Vara. Concluímos que o objeto representa a educação por processos e signos alinhados a abordagens pedagógicas tradicionais, desassociando-a do pensamento crítico e da ação libertadora.
Entre a sina trágica e a sanha violenta: narrativas jornalísticas de feminicídios no contexto da pandemia de Covid-19
Authors: Lage Leandro Rodrigues
Published: December 2023

O texto discute a relação entre a pandemia de Covid-19 e os casos de feminicídio registrados no Pará, a partir da análise de narrativas jornalísticas publicadas pelo portal G1 Pará entre 2020 e 2021. O ponto de partida argumentativo é a constatação da ausência de sistematização dos registros de feminicídios e violências contra mulheres durante a pandemia. Em seguida, discute-se o caráter estrutural das violências de gênero, e o feminicídio como expressão máxima dessas opressões. O exame da cobertura jornalística revelou dois aspectos principais: primeiro, a maioria das notícias aborda o feminicídio enquanto destino trágico de suas vítimas, jogando ênfase às cenas desses crimes; segundo, apenas as matérias de levantamentos de registros e ocorrências construíram um nexo entre o aumento de feminicídios e os impactos da pandemia de Covid-19.

Authors: Heller Barbara , Santa-Cruz Lúcia , Perazzo Priscila Ferreira , Faber Rosana Henrique , Neves Teresa Cristina
Published: December 2023

Heimat (1999), novela gráfica de Nora Krug, é o relato pessoal sobre sua família e a ascensão do nazismo na Alemanha. O objetivo de nossa reflexão consiste em analisar como as memórias construídas no processo de escrita do livro acionam uma nostalgia propositiva e provocam uma memória-ação, possibilitando reconciliação e perdão. A metodologia consiste em pesquisa documental, com análise interpretativa. A estrutura teórica se baseia em conceitos de autores de estudos de memória (Ricoeur, Pollak, Íñiguez-Rueda), nostalgia (Keithley, Pickering, Kalinina), filosofia e psicanálise (Heidegger e Freud). Concluímos que, ao recuperar seu passado por meio do exercício nostálgico propositivo, Nora Krug consegue perdoar e tolerar seus familiares, reconciliar seu passado e imaginar novos futuros.
Checagens sobre a covid-19 e enquadramento temático nas agências Fato ou Fake e Lupa
Authors: Martins Allysson , Teixeira Juliana
Published: December 2023

Este artigo, que integra uma pesquisa mais ampla, busca identificar quais são os padrões de fake news propagadas no processo de desinformação sobre a covid-19 e avaliadas pelas agências brasileiras de fact-checking Fato ou Fake e Lupa. Para isso, consideram-se as estratégias de espalhamento das informações falsas sobre a covid-19 no período de janeiro até setembro de 2020. Como metodologia, utilizamos parte dos procedimentos associados às análises do enquadramento midiático, focando sobretudo nas temáticas e etiquetas das informações checadas. Dos assuntos mais recorrentes na desinformação avaliada pelas agências, pode-se dizer que Política e Morte foram as duas principais, seguidas de perto por temáticas relacionadas à cura e à prevenção, envolvendo ainda as personalidades. A alta frequência de Política revela a polarização ideológica que se vive no Brasil, resvalando até numa crise sanitária global como a pandemia do novo coronavírus.
Earnings Management and Bank Liquidity Creation in an Emerging Market
Authors: Huynh Japan
Published: December 2023

This paper empirically examines the impact of bank earnings opacity on liquidity creation. Using a sample of commercial banks in Vietnam from 2007 to 2019, we find that more opaque banks tend to reduce liquidity creation growth. We further offer sharp evidence that the impact of earnings management on bank liquidity creation depends on bank-specific characteristics. More precisely, the negative impact of bank earnings management on banks’ core function is stronger for banks that are more poorly capitalised, less liquid, smaller and less profitable. With these findings, our work display implications on the supply-side effect (i.e., the limited access to funding of financially weak banks).
Exploring the Puzzles in Comparing Reliability Surrogate Measures for Water Distribution System Design: From the Dual Perspectives of Equal-Cost and Consistency
Authors: Huang Yuehua , Zhou Qianqian , WANG Qi , Zhao Zhiwei
Published: December 2023

Various reliability surrogate measures (RSMs) have emerged over last
three decades to design water distribution systems (WDSs). However,
there has yet to be a consensus on their rationalities. In this work, we
proposed a novel dual-perspective framework to examine RSMs’
rationalities, including the equal-cost perspective (ECP) by comparing
RSMs’ performance at three comparable equal-cost levels and the
traditional consistency perspective (TCP) widely used in other
comparative studies. RSMs’ performance was evaluated by the mechanical
reliability score (MRS) and the normalized resilience score (NRS). The
former compared fewer pipe failures under a snapshot scenario, while the
latter considered more comprehensive pipe failures using global
resilience analysis. We compared five well-known RSMs from the
literature, i.e., Network Resilience Index (NRI), Diameter-Sensitive
Flow Entropy (DSFE), Redundancy (REDU), Pipe Hydraulic Resilience Index
(PHRI) and Combined Entropy-Resilience Index (CERI). We verified their
performance for the multi-objective design of two medium-scale,
single-source WDSs, i.e., Hanoi and Fossolo. Results reveal that NRI is
the most rational measure. The rankings from NRS are similar to those
from MRS under the ECP; however, the two rankings vary significantly
under the TCP. The ECP is more reasonable than the TCP because it
measures network resilience and reliability from practical performance.
We recommend using the MRS+ECP framework to compare RSMs since it
reflects the critical aspect of global resilience with lower
computational overhead. Furthermore, some meta information, e.g., nodal
pressure head and demand, has the most significant impact on the
rankings of RSMs, inspiring the development of new and better RSMs.
Pan-Antarctic assessment of ice shelf flexural responses to ocean waves
Authors: Liang Jie , Pitt Jordan P.A , Bennetts Luke George
Published: December 2023

Ice shelves flex in response to surface ocean waves, which imposes
stresses and strains on the shelves that promote iceberg calving.
Previous modelling studies of ice shelf responses to ocean waves have
focussed on highly idealised geometries with uniform ice thickness and
flat seabeds. This study leverages on a recently developed mathematical
model that incorporates spatially varying geometries, combined with
measured ice shelf thickness and seabed profiles, to conduct a
statistical assessment of how fifteen Antarctic ice shelves respond to
ocean waves over a broad range of relevant wave periods, from swell to
infragravity waves to very long period waves. The results show the most
extreme responses at a given wave period are generated by features in
the ice shelves and/or seabed geometries, depending on the wave regime.
Relationships are determined between the median ice shelf response and
the median shelf front thickness or the median cavity depth. The
findings provide further evidence of the role of ocean waves in
large-scale calving events for certain ice shelves (particularly the
Wilkins), indicate a possible role of ocean waves in calving events for
other shelves (Larsen C and Conger), and the relationships determined
provide a method to assess how ice shelf responses are evolving with
climate change and project future scenarios.
Sea Ice and Ocean Response to a Strong Mid-Winter Cyclone in the Arctic Ocean
Authors: Watkins Daniel Mark , Persson Ola P G , Hutchings Jennifer K , Stanton Timothy P , Solomon Amy
Published: December 2023

Sea ice mediates the exchange of momentum, heat, and moisture
between the atmosphere and the ocean. Cyclones produce strong gradients
in the wind field, imparting stress into the ice and causing the ice to
deform. In turn, increased sea ice drift speeds and rapid changes in
drift direction during the passage of a cyclone may result in enhanced
momentum flux into the upper ocean.  During the year-long MOSAiC
expedition, an array of drifting buoys was deployed surrounding the R/V
Polarstern, enabling the characterization of sea ice motion and
deformation across a range of spatial scales. In addition, autonomous
sensors at a subset of sites measured the atmospheric and oceanic
structure and vertical fluxes. Here, we examine a strong cyclone that
impacted the MOSAiC site during January and February, 2020, while the
MOSAiC site was near the North Pole. 

The cyclone track intersected the MOSAiC buoy array, providing
an opportunity to examine spatial variability in sea ice motion during
the storm in unprecedented detail. A key feature of the storm was the
formation of a low-level jet (LLJ), first in the warm sector of the
storm, then growing to eventually encircle the central low. The highest
rates of ice motion and deformation coincide with effects of LLJ
transitions. Analysis of deformation using the Green’s theorem approach
indicates divergence and cyclonic vorticity as the LLJ enters the
region, and convergence and anticyclonic vorticity as the LLJ leaves;
maximum shear strain rate is enhanced throughout the LLJ’s passage.
While the vorticity signal is particularly clear, floe structure and
internal ice stresses result in high spatial variability in the
magnitude of divergence and shear strain rates, especially at smaller
scales. Increased current speed and shear in the upper layer of the
ocean during the passage of the LLJ resulted from ice drag forcing the
ocean mixed layer current. The results suggest an important role for
cyclone-forced ocean mixing in pack ice during the Arctic winter.
Detailed Bathymetry and Seafloor Backscatter Image Dataset for Monitoring Ecosystem Environment: Southern Ulleungdo
Authors: Choi Soon Young , Kim Chang Hwan , Kim Won Hyuck , Park Chan Hong
Published: December 2023

We obtained a detailed bathymetry dataset using multi-beam echo sounder around Neunggeol located at Southern part in Ulleungdo. The survey period was from September 1, 2019 and the bathymetry survey was carried out by RV Jangmok No2 of Korea Institute of Ocean Science and Technology. The instrument equipment used for the survey were Kongsbergs’s EM2040 (multi-beam echo sounder). The detailed bathymetry of the study area shows gradually depth change from about 4 to 190 m. The study area has relatively gentle slopes from the coast to 25 m and below about 125 m in depth, but a steep slope from about 25 to 125 m. The rocky bottom zones identified from detailed bathymetry and backscattered seafloor images are distributed in the northeastern sea of the coastal area, the central sea, and around Neunggeol. In particular, Neunggeol and the near large outcropping rock are tumulus-like submarine landforms, forming big vertical walls. The submarine cable buried between Ulleungdo and the Korean mainland appears in the northern seafloor of the survey area. Stopper stones and gravels sediment are distributed around it. The rocky bottom zone has a strong and irregular reflection intensity in the seafloor backscattered image and the sandy sediment zone has a relatively weak reflection intensity and a uniform pattern, so the two zones are well divided. We classified the sediment zones into fine-grained sediments, sandy sediments, and gravel-like sediments by using the different reflection intensities due to differences in sediment particle size in the seafloor image. Detailed bathymetry and seafloor backscattered image dataset around Neunggeol can be used as a basic data for habitat environment mapping.

Authors: Hwang Jeong Ho , Ko Myeong-Hun , Jung Sungmin , Yun Jong-Hak
Published: December 2023

The vertical connectivity of the river aquatic ecosystem was evaluated based on fish and artificial structures in Dorim stream, an urban stream in Seoul. As a result of a survey in the downstream area in 100.0 m of a total of 71 artificial structures, 13,728 individuals of fishes belonging to five orders, seven families, and 25 species were investigated, with the dominant species Zacco platypus and the subdominant species Rhynchocypris oxycephalus. As for endemic species, seven species were investigated and in terms of feeding characteristics, omnivorous species were the most common with 17 species (68%). Also an alien species, Poecilia reticulata was found. Fish species tended to decrease as the survey was conducted to upstream. Based on the movement characteristics of the fish species and the features of artificial structure survey results, the longitudinal continuity of each artificial structure was evaluated as 43 continuity, two damaged, 19 discontinuity, and seven absent. In inclined structures, stream velocity was found to be the main factor for discontinuity. In vertical structures, the down depth and head drop appeared to be the main factors for discontinuity. The results of this survey are expected to serve as basic data for the conservation of river aquatic ecosystems in the future.

Authors: Hicks Melanie , Bishop Jessica , Bicknell Brenton T. , Grayson Jessica , Woodworth Bradford A. , Cho Do-Yeon
Published: December 2023

Acute invasive fungal sinusitis (AIFS) is a rapidly progressing, life-threatening infection. The advent of immunomodulatory therapies has expanded the population susceptible to AIFS. In this case report, we describe a patient who defies the conventional profile of AIFS. This 70-year-old woman is immunocompetent and non-diabetic, with a history of multiple sclerosis (MS) and ongoing treatment with glatiramer acetate (GA), immunomodulator. She came to the emergency room due to acute vision changes, and images revealed an enhancing mass in the left pterygopalatine fossa. The diagnosis of AIFS was confirmed by biopsy in the operating room. Subsequently, anti-fungal therapies were initiated with a follow-up operative debridement. Follow-up magnetic resonance imaging (10 months since treatment) showed no progression of AIFS. GA was discontinued since the diagnosis, and MS has remained stable. Recognizing this unique group of atrisk patients is crucial, as early detection and treatment play a pivotal role in preventing significant morbidity and mortality.
Genetic and epigenetic aspects of the KISS1 and KISS1R genes in pubertal development and central precocious puberty: A review
Authors: Kwon Ahreum
Published: December 2023

The onset of puberty is a pivotal developmental milestone, and the release of gonadotropin-releasing hormone (GnRH) and luteinizing hormone is a key factor in the initiation of puberty. Both kisspeptin and its receptor (KISS1) and KISS1 receptor (KISS1R) play significant roles in regulating GnRH release, and consequently, the initiation of puberty. Central precocious puberty (CPP) is a condition in which the development of puberty is driven by the premature activation of the hypothalamic-pituitary-gonadal axis. In girls, CPP is primarily idiopathic, and genetic and epigenetic aspects of KISS1 and KISS1R have been implicated in its etiology. This review aimed to provide an overview of the current knowledge regarding mutations and polymorphisms in KISS1 and KISS1R associated with CPP. Additionally, this study provides a comprehensive review of the epigenetic regulation of the KISS1 gene in the context of puberty onset and CPP.
