The H-index is an unreliable research metric for evaluating the publication impact of experimental scientists
Authors: Akhtar M. Kalim
Published: February 2024

Research metrics are often used to assess the reputation of scientists. One commonly employed research metric is the H-index. It measures the publication impact of scientists. But how is it conceivable for a scientist with no distinguished track record in an experimental field to generate greater publication impact than prize-winning scientists? The answer, by resorting to a publishing strategy which places less focus on experimental innovations. I make the case here that the H-index is an abysmal metric for evaluating experimental researchers and that an alternative experiment-oriented metric is sorely needed to quantitate the work of experimental scientists.

Published: February 2024

The study evaluated the antioxidant properties of a crude methanolic extract (CME) from Rhaebo guttatus poison in mice over a period of 7 and 30 days. The mice were divided into groups and treated with different concentrations of the extract (0; 8 μg mL-1; 16 μg mL-1 and 32 μg mL-1 or vehicle; 100 μL/animal/day; via gavage). The liver samples were analyzed for status redox parameters as catalase (CAT), glutathione-S-transferase (GST), reduced glutathione (GSH) and thiobarbituric acid reactive substances (TBARS). The results showed that the CME caused changes in the levels of various antioxidants and oxidative stress markers. At 7 days, there was an increase in TBARS levels (8 μg mL-1 dose) and GST activity (16 μg mL-1 dose), and a reduction in GSH levels (32 μg mL-1 dose) compared to the control group. At 30 days, TBARS and GSH levels returned to control values in the same period, but GSH increased (32 μg mL-1 dose) compared at 7 days; GST activity remained high after 30 days for 32 μg mL-1 dose compared other groups and time of treatment (7 days). Overall, the study suggests that the extract modulates antioxidant properties per se that can affect various markers of status redox in the liver of mice, mainly 16 μg mL-1 dose demonstrated  to act under antioxidant enzymes in different times (7 or 30 days).

Published: February 2024

The Klampok River is one of the rivers that crosses the Bandungan, Bawen, Bergas and Pringapus Districts. The increase in the number of residents in the river basin which is not matched by the availability of land encourages the conversion of land functions that are not in accordance with their designation. The existence of the Klampok River as a water body receiving wastewater resulting from anthropogenic activities has caused the Klampok River to become polluted. Thus, it is important to study the water quality and water quality status of the Klampok River for nature conservation. This study aims to determine the water quality status of the Klampok River using the water quality index method, namely the National Sanitation Foundation – Water Quality Index (NSF-WQI) with reference to class II river water quality standards. NSF-WQI is a method that uses several specific parameters to determine river water quality.DO, fecal coliform, pH, BOD, nitrate, phosphate, temperature, turbidity, and total solids.The 2018 water quality index using the NSF-WQI method is in the range54.13 – 65.38with medium-good quality status. Meanwhile, the water quality index for 2019 using the NSF-WQI method is within the range35.47 – 66.60with moderate status, except for sampling point 6 which has bad status.

Published: February 2024

Actualmente, los rescatistas y el personal de emergencias que asiste a la comunidad en situaciones de desastre no cuentan con un tratamiento adecuado que proteja su salud mental. Las técnicas más ampliamente utilizadas como el debriefing y el defusing resultarían inefectivas para tal fin, e incluso perjudiciales a largo plazo. En el presente estudio se llevaron adelante dos cuasiexperimentos con 42 rescatistas bolivianos y 39 peruanos, para probar los efectos de la aplicación grupal de la técnica de Procesamiento Asistido en Situaciones Estresantes Recientes (PASER) en la reducción de los niveles de reactividad ansiosa vinculados al recuerdo de labores de rescate. Se utilizó el inventario de Autopercepción del Estado Emocional (APEEM), para evaluar la intensidad del recuerdo. Los resultados indicaron que la asistencia externa a la memoria de trabajo a través de la aplicación de la técnica PASER redujo significativamente la autopercepción de los niveles de perturbación emocional asociados al recuerdo en rescatistas peruanos t(38) = 6.642; p < .0001 y bolivianos t(24) = 7.452; p < .0001. Estas primeras observaciones indican que la técnica PASER,
aplicada de forma temprana y grupal a rescatistas y personal de emergencias, resultaría adecuada para la prevención de trastornos de ansiedad y estrés derivados de las tareas tensionantes de sus labores. La reducción temprana de esta sintomatología evitaría los frecuentes problemas de comorbilidad que conllevan los síntomas de ansiedad no tratados. Resultan necesarios nuevos estudios longitudinales para verificar la eficacia de esta intervención a largo plazo.

„Chwylowizm” Mykoły Chwylowego: szkoła literacka czy „zboczenie” ideologiczne?
Authors: Nowacki Albert
Published: February 2024

The works of Mykola Khvylovyi – one of the most recognizable writers of the 1920s – has many blank spots, which is why it is still the subject of scientific research in literary studies, political science and history. There is no doubt that the ideas of this Ukrainian writer significantly influenced not only the course of Ukrainian literary discussion but also the shape of contemporary Ukrainian literature. The aim of this article is to attempt to examine the phenomenon known as “khvylovism” and to prove that it is a phenomenon artificially created by the ideologists of the communist party in the 1920s. The author pays particular attention to the fact that “khvylovism” cannot be treated as a system of the writer’s political views but as a concept for the development of independent Ukrainian literature
Investigating translanguaging strategies and online self-presentation through internet slang on Douyin (Chinese TikTok)
Authors: Li Ziqi , Wang Li
Published: February 2024

This study explores the translanguaging strategies used in internet slang on Douyin, a popular social media platform in China. By analyzing 331 examples (encompassing 313 translanguaging strategies), we investigate how individuals utilize various translanguaging resources, including multimodal, multilingual, multisemiotic, and multisensory resources, to manage their online self-presentation. Our findings suggest that multilingual resources, such as new Chinglish, Pinyin initialism, and hybrid words (combining Chinese, English, and Arabic numerals), were the most frequently used strategies. Additionally, we found that multisensory resources, including homophonic puns and modal particles, were also commonly utilized. In contrast, multimodal resources, such as emojis, and multisemiotic resources, such as keyboard-generated emoticon, hashtag, and punctuation mark, were less frequently employed. These findings reveal that Chinese internet users display a high degree of creativity and adaptability in their online communication, drawing on a wide range of linguistic and semiotic resources to express their identities and project their desired image. Overall, this study highlights the importance of translanguaging in online communication and its role in shaping self-presentation in the digital age.

Authors: Eichinger Michael , Shah Karan , Palt Niklas , Eichlseder Michael , Pichler Alexander , Zoidl Philipp , Zajic Paul , Rief Martin
Published: February 2024

Objectives

Blood gas analysis, including parameters like lactate and base excess (BE), is crucial in emergency medicine but less commonly utilized prehospital. This study aims to elucidate the relationship between lactate and BE in various emergencies in a prehospital setting and their prognostic implications.

Methods

We conducted a retrospective analysis of prehospital emergency patients in Graz, Austria, from October 2015 to November 2020. Our primary aim was to assess the association between BE and lactate. This was assessed using Spearman’s rank correlation and fitting a multiple linear regression model with lactate as the outcome, BE as the primary covariate of interest and age, sex, and medical emergency type as confounders.

Results

In our analysis population (n=312), lactate and BE levels were inversely correlated (Spearman’s ρ, −0.75; p<0.001). From the adjusted multiple linear regression model (n=302), we estimated that a 1 mEq/L increase in BE levels was associated with an average change of −0.35 (95 % CI: −0.39, −0.30; p<0.001) mmol/L in lactate levels. Lactate levels were moderately useful for predicting mortality with notable variations across different emergency types.

Conclusions

Our study highlights a significant inverse association between lactate levels and BE in the prehospital setting, underscoring their importance in early assessment and prognosis in emergency care. Additionally, the findings from our secondary aims emphasize the value of lactate in diagnosing acid–base disorders and predicting patient outcomes. Recognizing the nuances in lactate physiology is essential for effective prehospital care in various emergency scenarios.

Authors: Rosen Aviana O. , Bergam Lauren , Holmes Ashley L. , Krebs Emma , Moreno Melanie , Muñiz Geycel S. , Huedo-Medina Tania B.
Published: February 2024

Introduction

LatinX youth in the U.S. are disproportionately affected by HIV and STIs, commonly attributed to a lack of diagnostic testing and regular physician consultations to address sexual health. These disparities have been exacerbated by the COVID-19 pandemic. This meta-analysis seeks to assess the efficacy of behavioral interventions among LatinX youth in the U.S. that aim to increase engagement in sexual health services (i.e., STI/HIV testing, physician consultations).

Content

Following PRISMA guidelines, seven electronic databases were searched. We systematically extracted data with a coding form, and effect sizes were obtained from each study on HIV/STI testing outcomes and physician consultation. Moderator analyses were run for demographic and intervention characteristics.

Summary and Outlook

Of nine included studies, the interventions created a small-to-moderate effect on increased engagement of sexual health services (d
+=0.204, 95 % CI=0.079, 0.329). Moderator analyses showed that interventions including the following characteristics were most efficacious at facilitating care services: community-based or online setting, access to diagnostic testing, social media/remote components, parental involvement, and longer session duration. This meta-analysis provides informative results regarding behavioral interventions that have proven efficacious in facilitating engagement in sexual health services among LatinX youth. Most prominently, interventions that are remote or through social media, community-based, and incorporated parents had large positive effects. These findings prove useful for the ongoing COVID-19 pandemic situation and provide guidance for targeting LatinX youth to engage them in sexual health services as primary and secondary STI and HIV prevention.

The new era of cardiovascular research: revolutionizing cardiovascular research with 3D models in a dish
Authors: Yang Yuan , Yang Hao , Kiskin Fedir N. , Zhang Joe Z.
Published: February 2024

Cardiovascular research has heavily relied on studies using patient samples and animal models. However, patient studies often miss the data from the crucial early stage of cardiovascular diseases, as obtaining primary tissues at this stage is impracticable. Transgenic animal models can offer some insights into disease mechanisms, although they usually do not fully recapitulate the phenotype of cardiovascular diseases and their progression. In recent years, a promising breakthrough has emerged in the form of in vitro three-dimensional (3D) cardiovascular models utilizing human pluripotent stem cells. These innovative models recreate the intricate 3D structure of the human heart and vessels within a controlled environment. This advancement is pivotal as it addresses the existing gaps in cardiovascular research, allowing scientists to study different stages of cardiovascular diseases and specific drug responses using human-origin models. In this review, we first outline various approaches employed to generate these models. We then comprehensively discuss their applications in studying cardiovascular diseases by providing insights into molecular and cellular changes associated with cardiovascular conditions. Moreover, we highlight the potential of these 3D models serving as a platform for drug testing to assess drug efficacy and safety. Despite their immense potential, challenges persist, particularly in maintaining the complex structure of 3D heart and vessel models and ensuring their function is comparable to real organs. However, overcoming these challenges could revolutionize cardiovascular research. It has the potential to offer comprehensive mechanistic insights into human-specific disease processes, ultimately expediting the development of personalized therapies.

The effects of viscosity on the structure of shock waves in a van der Waals gas
Authors: Anand Raj Kumar , Singh Sewa
Published: February 2024

The structure of viscous shock-front has been investigated in a van der Waals gas between the boundary conditions for x = −ε and x = +ε considering the flow of a gas to be viscous and one-dimensional. The exact solutions for the flow parameters, fluid velocity, pressure, temperature, and change-in-entropy in the shock transition region have been found in view of the equation of state for van der Waals gases. The effects due to the coefficient of viscosity, shock strength, and nonidealness parameter have been analyzed on the structure and flow variable in the shock transition region. The results confirm that the thickness of shock-front increases with increasing value of the coefficient of viscosity and decreases with increasing value of the shock strength and nonidealness parameter of the gases.
Establishment and Operation Methods of Contemporary Seowon: Focusing on ‘Hwasan Seowon’ in Chilgok-gun
Authors:   Institute of Korean Cultural Studies Yeungnam University, Chung Jaeyoung
Published: February 2024

This paper examines the construction process, activities, and operation methods of contemporary Seowon, focusing on Hwasan Seowon located in Chilgok-gun. Hwasan Seowon is characterized by its relocation and maintenance of Hwasanseodang, its predecessor, to Yeungnam University Folk Village, and the restoration of the Seowon building.
The Hwasan Seodang clan formed the Hwasan Seowon Preservation Society while restoring Hwasan Seowon. The Hwasan Seowon Preservation Society secured the efficiency of the operation of the seowon by separating all roles related to the seowon from the Hwasan Seodang clan.
However, the role of this preservation society is rather helping the clan's activities. The formation of the Preservation Society can be seen as the establishment of a dual operating system in a complementary relationship between the Hwasan Seodang clan and the Hwasan Seowon Preservation Society. This is a strategic separation of complementary relationships. In other words, it is a complementary separation.
In addition to the management of seowon, the role of the preservation society in fair and efficient management of the property of the clan increased due to urbanization is recognized as important.
This methods of operation of seowon contributes to establishing a modernized identity of ethnic groups in contemporary urban society and securing emotional stability.
The Formation and Division of Bonglim-sanmun in the Era of Late Silla and Early Goryeo
Authors:   Institute of Korean Cultural Studies Yeungnam University, Bae Sang-hyun
Published: February 2024

The era from late Silla to Early Goryeo Dynasty was a period requiring enormous transition to a new society in which armed conflicts occurred in every corners of the politically-divided states and men of local influence tried to gain political power. It was also a time when a con sequen tial priority should be given to stabilize the local refugees and relieve the starved people. In these circumstances Zen monks were committed to practical asceticism.
Bonglim-sanmun was founded by Simhui, a Buddhist disciple of Monk Hyeonuk, in the long course of pilgrimage. It was divided and developed by his followers who studied in Tang Dynasty and returned to their homeland with the royal devotion of Silla and strong support of King Taejo of Goryeo. This thesis aims to understand the process focusing on the epitaphs of the monks Chungdam, Chanyu and Hongjun as well as their social activities.
The religious division of Bonglim-sanmun began in earnest during the funeral in memory of his life and death after Simhui’s visit to Gyeongju. This trend, not irrelevant to the policy to actively embrace Buddhism in Goryeo era, is understood as Simhui’s diagnosis on the religion at the time the influence of positive will to redeem all the lives in the world. The campaign led to the formation of independent Buddhist sects such as Godalwon, Heungbeop Zen Institution and Gyeongcheong Institution, besides Bonglim Temple.
The religious segment of Bonglim-sanmun is understood as the priest’s Zen spirit to widen Buddhist teachings to the fullest. It also explains his disciples’ cooperation with King Taejo’s efforts for national unification. Such activities are seen to have much in common with the open and practice-oriented Zen ideology of the key priests.
Change of a Lineage Village and Urban History of Gyeongsan-Si
Authors:   Institute of Korean Cultural Studies Yeungnam University, Jang Minyoumg , Lee Chang Un
Published: February 2024

This study examines the changes experienced by a lineage village near Gyeongsan City, adjacent to a major urban center, during the process of urbanization. To understand the impact of urbanization on the social and economic aspects of rural areas near Gyeongsan City and its various effects on lineage organization, this study applies a research method of urban history, focusing on correspondence in response to urbanization over different periods.
The cultivation of cash crops and an increase in diversified farming accelerated the outflow of lineage members to the city, leading to the influx of outsiders and the formation of autonomous cooperative groups among those who were traditionally marginalized in the lineage community. As urbanization progressed, the structure of intra-lineage property changed, resulting in organizational transformations to effectively manage it. Consequently, the traditional functions and aspects of lineage communities focused on hierarchy and lineage have diminished, giving rise to intensified conflicts among lineage members over the management and disposal of intra-lineage property. The study suggests that the implications of these changes in suburban lineage villages due to urbanization highlight the need for institutional mechanisms applicable to the realistic functional shifts within lineage communities and the management of intra-lineage property in contemporary society.

On the other hand, this study can be said to be an attempt to understand the stone pagodas by focusing on the presentness of stone pagodas, and using legends of the people who have lived together with stone pagodas, as a mean. Therefore, this study investigates around 40 stone pagodas with their own legends, categorises those legends, and examines the significance of the legends in the study of stone pagodas in terms of era, region and people.
As a result, it is found that the majority of stone pagodas having their legends, were constructed during Goryeo period in the era aspect, in the Chungcheong-do and Jeolla-do in the regional perspective. In addition, it becomes aware that the people felt more familiar to the appearance of stone pagodas with local characteristics an d un ique design than on es with formalized and general shape, through the facts that non-mainstream stone pagodas such as Baekje style stone pagodas and Stone brick pagodas, which have a regional cluster, occupy most of legends of the stone pagodas. It is seen that, in terms of the people, the historical consciousness of the people was reflected to legends of the stone pagodas, and those were used to commemorate a specific object or to be in folk belief aspect. This study has the differentiation from previous ones by not limiting a way of a study of stone pagodas to the buddhistic approach, and the style and chronology.

Beausejour, JP, Guinto, G, Artrip, C, Corvalan, A, Mesa, MF, Lebron, MA, and Stock, MS. Successful powerlifting in a unilateral, transtibial amputee: A descriptive case series. J Strength Cond Res 38(5): e243–e252, 2024—There are no reports in the literature of powerlifting success after amputation. We had the unique opportunity to characterize functional outcomes, strength, muscle contractility and size, and corticospinal excitability in an accomplished, competitive powerlifter (best competition squat = 205.0 kg, deadlift = 262.7 kg) with a unilateral, transtibial amputation relative to amputee controls. Four men (age range = 23–49 years) with unilateral, lower-limb amputation (3 transtibial, 1 transfemoral) participated in 1 laboratory visit. We assessed 10-m gait speed, the timed up and go (TUG) test, 5-time sit-to-stand performance (5TSTS), contractile properties of the vastus lateralis (VL) and medial gastrocnemius by tensiomyography, and VL cross-sectional area (CSA) by ultrasonography. Unilateral assessments for the intact limb included isokinetic knee extension and flexion torque and power and transcranial magnetic stimulation derived corticospinal excitability. An interview with the powerlifter provided contextual perspective. Compared with the control subjects, the powerlifter performed the 5TSTS faster (6.8%), exhibited faster VL contraction times (intact limb = 12.2%; residual limb = 23.9%), and showed larger VL CSA for the intact limb (46.7%). The powerlifter exhibited greater knee extension and flexion peak torque and mean power, particularly at 180°·s−1, as well as greater corticospinal excitability for the intact VL (65.6%) and tibialis anterior (79.6%). By contrast, the control subjects were faster in the TUG (18.3%) and comfortable (13.0%) and fast (21.4%) in the 10-m walk test. The major themes of our interview included needing to modify lifting mechanics, persistence, and remarkable pain tolerance. Our findings highlight the impressive neuromuscular adaptations that are attainable after lower-limb amputation.

Published: February 2024

In brief

Seahorses exhibit male pregnancy and are thus valuable comparative models for the study of the physiology and evolution of pregnancy. This study shows that protein is transported from fathers to developing embryos during gestation, and provides new knowledge about paternal contributions to embryonic development.

Syngnathid embryos (seahorses, pipefishes and seadragons) develop on or in the male in a specialised brooding structure (brood pouch). Seahorse brood pouches supply nutrients, including lipids, to developing embryos (patrotrophy). We tested the hypothesis that proteins, vital for gene regulation and tissue growth during embryogenesis, are also transported from father to embryos, using the Australian pot-bellied seahorse, Hippocampus abdominalis. We used dry masses and total nitrogen content to estimate the total protein content of newly fertilised egg and neonate H. abdominalis. Neonates contained significantly greater protein mass than newly fertilised eggs. This result indicates that paternal protein transport to developing embryos occurs during H. abdominalis pregnancy. This study is the first to show paternal protein transport during pregnancy in seahorses, and furthers our understanding of paternal influence on embryonic development in male pregnant vertebrates.
Divulgación de la literatura infantil a través de cuentas de influencers en Instagram: factores que influyen en el nivel de engagement
Authors: López Verdejo Miguel , Hoster-Cabo Beatriz , Sánchez-Canales Vanesa
Published: February 2024

Se analiza el uso que hacen de Instagram autores de cuentas con alto impacto relacionadas con divulgación de literatura infantil y las respuestas de sus seguidores a los distintos tipos de publicaciones mediante el engagement para comprobar su interés por el contenido. La muestra se extrae de 220 publicaciones correspondientes a 11 cuentas sin ánimo de lucro relacionadas con divulgación de literatura infantil. Se realiza un estudio exploratorio mixto, identificando las características de las cuentas y analizando su contenido mediante la adaptación de un instrumento de recogida de información previamente validado. Los datos se recolectan y analizan en Excel y se comparan las cuentas con mayor y menor engagement. Entre otros resultados, destaca que generalmente presentan lecturas recomendadas junto a materiales docentes varios para educación infantil y el engagement decrece al aumentar el número de seguidores. Discusión y conclusiones: las recomendaciones suelen limitarse a referencias bibliográficas y una somera alusión al contenido; aquellas publicaciones que obtienen mayor interacción contienen, de manera general, reels, alusiones a poesía infantil o pretenden ayudar en la elaboración de recursos didácticos. El procedimiento utilizado es aplicable a otras muestras.

Reactivity is an important quality parameter form some grades of pulp, but its estimation is usually complex and time demanding. The study verified the possibility to utilize an alternative rheological approach to investigate pulp reactivity rapidly and with limited effort. 12.5 mL of pulp at 1.5% consistency was dissolved in 12.5 mL bis(ethylenediamine) pulp copper (II) hydroxide solution (CED) 1M The reaction was monitored by a torque rheogram and its two indices: the optimal dissolution time (ODT) and the initial dissolution rate (IDR). The method used to assess pulps either hornified to different extents or subjected to enzymatic hydrolysis. ODT was shown to decrease with increasing pulp swelling, while IDR reported the opposite trend. Both the indices were shown to be sensitive to pulp treatments. However, the ODT showed larger differences between hardwood and softwood pulps. The method had reasonable statistical reliability and required only 1.5 h per measurement.

Published: February 2024

This paper is concerned with practical fixed-time (FT) stabilization problem of discretetime impulsive switched port-controlled Hamiltonian systems (DISPCH). First, starting with discrete-time port-controlled Hamiltonian systems, a novel controller is presented to achieve practical FT stability of the obtained closed-loop system. Moreover, in order to well handle the abrupt changes at switch moments in practical switched systems, another novel controller is presented in terms of positive-order Lyapunov functions approach and range dwell time method to make discrete-time impulsive switched port-controlled Hamiltonian system practical FT stable. Ultimately, the validity of proposed methods is illustrated by simulations.
Scales, belts, and pyramids: back to the future of digital healthcare
Authors: Jones Graham B
Published: February 2024

Adoption of digital health technologies has been relatively limited despite their potential to have meaningful impact on health. For deployment to improve patient adherence, it is imperative to link desired behavioral changes to patient value chains, many of which are instilled at an early age. There exists a clear opportunity for parents, schools, and communities to play a mentoring role in the deployment of digital health tools by future generations, ahead of their journey to becoming patients in the managed healthcare system. In addition, for existing adult populations and senior citizens, appropriate motivating factors can be deployed to inspire effective use of digital adherence tools and contribute to enhanced health outcomes in the immediate future. Coupled with new approaches in managed care and health insurance provisions the full promise of digital health technologies might then be realized in the nearer term.
THE IMPACT OF COVID-19 ON PREGNANCY OUTCOMES AND ITS EFFECTS ON OXIDATIVE STRESS – MINI REVIEW
Authors: Al Dahwi Rafaah S. Jasem
Published: February 2024

Viral infections during pregnancy are not uncommon and may cause different complications both: 1) on the fetus; depending on which trimester when the woman gets infected, in addition to the 2) maternal complications.
During the last decades, several cases of coronavirus like SARS, MERS have been identified in different regions of the world especially in the Middle East and Africa. According to the clinical experience of pregnancies that were complicated with infection by these types of coronaviruses, has led to pregnant women being considered potentially vulnerable to severe SARS-CoV-2 infection.
The impact of SARS-CoV-2 in pregnancy remains to be found , and researches are required to determine the effects on implantation, fetal growth and development, labor, and neonatal health and the role of the infection during pregnancy on the oxidative stress.

We report the ﬁrst record of Pontoporia blainvillei (Gervais & d’Orbigny, 1844), Franciscana or La Plata River Dolphin, along the coast of Arraial do Cabo, southeastern Brazil. On 8 October 2017, a newborn was stranded in the surf zone of Prainha Beach and was returned to the sea. Although an occasional record, ﬁlls a distribution gap of the species’ occurrence on the coast of Rio de Janeiro state and, consequently, helps clarify the distribution pattern of P. blainvillei along the coast of the Brazil.
The Role of Political Party Elites in Reconciling Identity Political Conflicts After the 2019 Presidential Election: A Consensus Perspective
Authors: Ulum Bahrul
Published: February 2024

The research aims to analyze the role of political party elites in reconciling identity political conflicts after the 2019 presidential election carried out by political party elites from the perspective of Ralf Dahrendorf's social conflict theory. The research approach used is qualitative with descriptive methods. The data was collected using documentation, namely journal articles and news articles about reconciliation after the 2019 presidential election—news articles taken from kompas and detik.com. The analysis used is content analysis. The findings from this research are that the consensus agreed upon by the political party elites that intersect has a significant influence on society, which previously experienced polarization due to the strengthening use of identity politics in the 2019 presidential election. This research is useful in the realm of political sociology and also social development. Based on the research findings, this research is novel in the perspective that conflicts that occur between groups can be negotiated and made mutual agreements for the progress of a larger organization.
