Published: July 2024

Data Envelopment Analysis is a crucial tool for evaluating the performance of insurance companies, considering its ability to handle multiple inputs and outputs. This study provides a comprehensive bibliometric analysis of Data Envelopment Analysis (DEA) application in the insurance industry from 2010 to 2023, examining 405 documents from 432 sources. Materials from academic databases (Web of Science and Scopus) were used for the analysis. The methodological flow included three stages. For analysis, two sets of keywords were identified: one set oriented toward DEA and the other tailored to the Insurance Industry domain. To analyze and visualize the data, VOSviewer software, version 1.6.19, and RSTUDIO were used. This paper highlights the evolution of DEA methodologies, incorporating advanced techniques like Artificial Intelligence and Machine Learning, and addresses emerging trends such as digital transformation, customer-centric assessments, and sustainability. The analysis reveals significant geographical and sectoral differences in efficiency assessments, with higher efficiency levels typically found in developed markets such as North America and Europe compared to emerging markets in Asia and Africa. It also notes the distinctive efficiency patterns between life and non-life insurance firms, influenced by product complexity and market competition. The findings indicate that DEA remains versatile and essential for performance evaluation in the insurance industry, adapting to challenges through methodological advancements.
Real hopes in antiemetic therapy
Authors: Kogoniya L. М.
Published: July 2024

Anticancer drug therapy has made significant progress in the last two decades. However, the correction of adverse events and complications that arise during treatment requires special attention. Most often, special antitumor therapy can cause side effects from the gastrointestinal tract. Chemo-induced nausea and vomiting is the most common adverse event associated with drug therapy of cancer. It significantly worsens the well-being and quality of life of patients. With multiple cycles of chemotherapy, episodes of both acute and delayed nausea/vomiting may occur. There are several pharmacological groups of antiemetics. The most effective regimen for the prevention of chemotherapy-induced nausea and vomiting is a combination of serotonin receptor (5-HT3) and neurokinin receptor (NK-1) antagonists. It provides high symptom control in both the acute and delayed phases of nausea/vomiting. Palonosetron, a new-generation serotonin receptor antagonist, differs from firstgeneration 5-HT3 receptor antagonists in its stronger and longer-lasting antiemetic effect with a comparable safety profile. Oral administration of palonosetron is not inferior in effectiveness to its intravenous administration. An oral combination drug containing the NK-1 antagonist netupitant and the 5-HT3 antagonist palonosetron is highly effective in preventing nausea and vomiting in moderately and highly emetogenic drug regimens. The long half-life of both drugs and their high affinity to their receptors provide a long-lasting and persistent effect even with a single dose. This combination is particularly effective in relieving symptoms of delayed nausea/vomiting. A number of clinical studies have demonstrated that a single oral dose of netupitant/palonosetron combination is significantly more effective than 3-day aprepitant-based regimens in preventing delayed chemotherapy-induced nausea and vomiting. In addition, the netupitant/palonosetron combination may be cost-effective by reducing the cost of managing of complications of poorly controlled nausea and vomiting.

Introduction. The past COVID-19 pandemic has influenced the course of many diseases including endocrine pathology. However, little is known about the clinical and pathogenetic features of thyroid pathology of the post-COVID-19 period.

Aim. Evaluate the clinical and pathogenetic features of thyropathies diagnosed during the post-COVID-19 period.

Materials and methods. A cross-sectional study included 250 patients with newly diagnosed thyroid diseases. 73 participants denied a history of COVID-19 and 177 suffered from it within the previous 9 months. Thyroid status and thyroid ultrasound examination were assessed. IgG SARS-Cov-2 levels were tested in 40 patients with a history of COVID-19. Fine needle aspiration biopsy was performed in 61 patients including 41 with a history of COVID-19. In the main group, all the samples were additionally investigated by immunocytochemical analysis with SARS-CoV-2 protein antibodies.

Results. Among the patients with COVID-19 history higher levels of fT4 (13.6 [12.4; 15.5] vs 12.8 [11.0; 15.3] pmol/l, p = 0.046) and a lower proportion of patients with euthyroidism (122 (68.9%) vs 59 (80.8%), p = 0.037) were detected. In the main group there were more cytological samples with macrophages accumulations (16 (39.0%) vs 2 (10.0%), p = 0.017), however, immu-nocytochemical study did not reveal any SARS-Cov-2-positive samples. During the post-COVID-19 period, approximately 60% of patients with subclinical thyroid dysfunctions experienced spontaneous normalization. There were correlations between IgG SARS-Cov-2 levels and parameters characterizing the structural and functional state of the thyroid gland.

Conclusion. The most typical clinical feature of post-COVID-19 thyropathies was a smaller proportion of individuals with euthyroidism. Mild thyroid dysfunctions identified during the post-COVID-19 period tended to develop spontaneous normalization in 60% of cases. The immunocytochemical tests indicate the absence of SARS-Cov-2 persistence in the thyroid tissue. COVID-19- associated immunopathological reactions are involved in the pathogenesis of post-COVID-19 thyropathies.

Introduction. Lung cancer remains the leading cause of cancer-related deaths worldwide. For the first time in 30 years, the randomized clinical studies employing immunochemotherapy showed a significant increase in median overall survival for patients with advanced small cell lung cancer. However, no significant predictors of the immunochemotherapy effectiveness were identified.

Aim. To improve long-term outcomes of treatment of patients with advanced small cell lung cancer through search for predictors of the immunochemotherapy effectiveness.

Materials and methods. A total of 35 patients (11 women and 24 men) with advanced small cell lung cancer who received immunochemotherapy with atezolizumab combined with etoposide and carboplatin as first-line treatment were included in the analysis. The average age for patients was 61 years. At the immunochemotherapy baseline, 10 patients had stage IVA disease, 24 patients had stage IVB disease, and one patient had stage IIIB disease. We retrospectively assessed the prognostic impact on the median progression-free survival and overall survival of such factors as leukocytosis, thrombocytosis, lactate dehydrogenase level, neutrophil to lymphocyte ratio, fibrinogen level, blood type.

Results. Median progression-free survival was 6.2 (95% CI 4.6–7.8) months, median overall survival was 16.0 (95% CI 9.4– 22.6) months. There was an increasing trend in median progression-free survival, but without statistically significant differences in leukocytosis, thrombocytosis, elevated fibrinogen levels and normal lactate dehydrogenase levels at the beginning of therapy. The neutrophil to lymphocyte ratio at the beginning of therapy had a significant impact on median progression-free survival. There was a statistically significant increase in median progression-free survival from 4.5 (95% CI 3.9–5.1) to 6.9 (95% CI 5.6–8.2) months when the neutrophil to lymphocyte ratio was < 3. A significant decrease in median progression-free survival – 5.0 (95% CI 3.5–6.5) months was also observed in patients with blood group B (III) vs 6.2 (95% CI 4.7–7.7) months for patients with a different blood group (p = 0.047). Factors such as leukocytosis, thrombocytosis, fibrinogen level, lactate dehydrogenase level and neutrophil to lymphocyte ratio did not have a significant impact on overall survival. Patients with blood type B (III) showed significantly worse survival: median overall survival was 12.1 (95% CI 9.3–14.9) months in blood group B (III) and was not achieved in patients with other blood groups (p = 0.017).

Conclusion. The significance of the identified predictors of the immunochemotherapy effectiveness in patients with advanced small cell lung cancer should be confirmed with the larger sampling size using a multivariate analysis. The study continues a recruitment of patients.
Neuroblastoma in children: What has changed in the 21st century
Authors: Volkova A. R. , Vakhitov Kh. M. , Rashitova E. L. , Zakirova A. M.
Published: July 2024

Among the childhood cancers, neuroblastoma ranks fourth. This tumour is considered the most common extracranial malignant neoplasm in children and was first described in 1865 by the German scientist Rudolf Virchow. Neuroblastoma has the unique ability to undergo increased cell differentiation and transform into ganglioneuroma. In some cases, the disease can be asymptomatic and may undergo spontaneous regression or maturation into a benign tumour. However, neuroblastoma often has an aggressive course with early metastasis. Due to the ambiguity of clinical symptoms, the primary diagnosis of neuroblastoma in children requires pediatricians to be acutely aware of oncological emergencies and initial signs such as increased abdominal size and asymmetry, neurological symptoms, pain, and dysuria. In low-risk patients, minimal therapy, including surgery alone, achieves long-term survival in more than 90% of cases. Achieving similarly high survival rates in the intermediate-risk group is possible only with the use of modern polychemotherapy regimens in combination with surgical treatment and, in some cases, radiation therapy. High-risk patients require a combination of the aforementioned methods together with autologous or allogeneic hematopoietic stem cell transplantation, with long-term overall survival rates not exceeding 50%. The most favorable prognosis is seen in patients with localised disease under the age of one year. This article describes the features of tumour development, the course of the disease, and the evolution of diagnostic and therapeutic strategies from the past to the present.

Aim

To synthesize silver nanoparticles (AgNPs) using Terminalia arjuna bark extract (TABE) and investigate their efficacy in controlling Aedes aegypti and Aedes albopictus mosquitoes

Background

This research investigates the utilization of Terminalia arjuna bark extract to produce silver nanoparticles (AgNPs) as a means of controlling disease-carrying mosquitoes Aedes aegypti and Aedes albopictus. The nanoparticles are analyzed using UV-Vis spectrophotometry, XRD, FT-IR analysis, and SEM. In silico studies provide additional investigation into the larvicidal properties of T. arjuna phytochemicals, providing valuable insights into their effectiveness as biocontrol agents.

Objectives

The current research aimed to synthesize silver nanoparticles (AgNPs) using the Terminalia arjuna bark extract (TABE-AgNPs) in controlling the disease-transmitting vectors such as Aedes aegypti and Aedes albopictus.

Methods

The size of the synthesized nanoparticles was determined using the UV-Vis spectrophotometer, XRD, and FT-IR analysis, and the morphology of the particles was measured using the SEM. The size of the synthesized particles ranged from 28.57 to 79.38 nm. An in silico larvicidal and insecticidal potential of Terminalia arjuna chemical constituents are also carried on the key proteins of mosquitoes using the Schrodinger module.

Results

The biosynthesized AgNPs were investigated for larvicidal effect on the dengue-causing vectors such as Aedes aegypti and Aedes albopictus. The AgNPs showed a significant larvicidal impact on the mosquitoes after 24 and 48 hours, with the LC50 of 6.49 and 4.50 ppm, respectively. The in-silico research indicates that the chosen phytochemicals of T. arjuna exhibit larvicidal properties due to their high binding affinities with key mosquito proteins of A. aegypti and A. albopictus. Specifically, leucodelphinidin, mannitol, and leucocianidol were found to exhibit mosquitocidal properties. These revealed their insecticidal effects by showing the binding affinities and docking scores of -7.11584 kcal/mol for FK506-binding protein 12, -7.78699 kcal/mol for Arylalkylamine N-acetyltransferase 7, -5.96534 kcal/mol for salivary protein 34k2, -5.78943 kcal/mol for Odorant-binding protein and -7.21602 kcal/mol for young juvenile hormone-binding protein.

Conclusions

Eventually, the present research concluded that the phytochemicals T. arjuna might act as capping and reducing elements during the fabrication of nanoparticles that lead to the potential larvicidal effects after capping with silver. This study also suggested that green synthesized nanoparticles could be potential biocontrol agents in controlling the populations of disease-transmitting vectors.

Published: July 2024

Background

Despite developments in dental shade selection methods, shade selection is still a challenge affecting aesthetic outcomes. Accurate color evaluation is an important factor in dental restoration procedures. An accurate determination of tooth color is crucial for obtaining a definitive result.

Aim and Objective

This study aimed to evaluate the factors affecting the shade-taking accuracy of digital shade-taking devices. The objective was to evaluate the effect of distance, contact angle, moisture condition, and surrounding light on the shade-taking accuracy of two digital shade-taking devices.

Materials and Methods

Bovine teeth were used and thawed in running tap water. The soft tissue remnants are cleansed using a scalpel and polished using 1500 SiC. The shade and color parameters ∆E were recorded at different distances, angles, moisture, and surrounding light.

Results

One-way ANOVA showed a statistically significant color shifting at 2mm and 3mm measuring distance for both devices (p<0.05). A contact angulation of 150, 300, and 450 significantly shifted the color measurement by both devices(p<0.05). In the case of moisture, both devices showed color shifting in certain conditions, however, VITA5 was less affected by the moisture. In the case of surrounding lightness, adding dental unit light significantly shifted the color parameter for VITA5 (p= 0.004), however, it was statistically insignificant for VITA4 (p=0.537)

Conclusions

The distance, angulation, moisture, and surrounding light can affect the shade-taking accuracy of the digital shade guide. The clinician must maintain a standard condition to accurately take shade using a digital shade guide.

Authors: Liju R. , Rajkumar Eswaran
Published: July 2024

Water is necessary for the growth of humans and all other living things.
Water is becoming scarce due to industrialization and its rapid growth, and the water
ecosystem is negatively impacted by the direct release of wastewater into the
environment. The textile, tanning, coating, plastics, paint, printing, and other industries,
discharge dyes and pigments into the environment. One major problem is to remove
dyes and pigments from industrial wastewater in a inexpensive and environmentally
friendly way. Before they are released into the environment, there are several ways to
mitigate the situation, including chemical, biological, and chemical oxidation
processes. The advanced oxidation process (AOP) is a widely employed technique for
eliminating contaminants from water and wastewater. The dye molecules are broken
down by a Fenton and Fenton-like mechanism, in which the breakdown of hydrogen
peroxide produces hydroxyl radicals. This chapter focuses on the most current
advancements and various strategies used in the Fenton and/or Fenton-like processes
used to degrade the dye molecules.

This chapter deals with degrading dyes using Metal-Organic Frameworks as
a heterogeneous catalyst. Metal-Organic Frameworks (MOFs) are an excellent material
for dye degradation due to their multifunctionalities, such as semiconducting
properties, ease of use with controllable structures, high surface area, and enormous
active sites. MOFs exhibit a promising photocatalytic activity under UV–visible light
irradiation due to band gap presence. Several MOFs show an excellent reusability
performance even after a few consecutive cycles. The MOFs used to degrade dyes are
classified as bare MOFs (Lewis acid MOF, Brønsted Base MOF), MOFs@SiO2
,
magnetic MOFs, MOF nanocomposites, ionic MOFs, bimetallic MOFs, nanoparticles
doped MOFs, etc., The mechanism of dye removal and photocatalytic degradation of
organic dyes using MOFs and the detailed pros and cons of these materials are

Published: July 2024

Cu(In,Ga)Se2 (CIGS) is a promising absorber material for thin film solar cells
because of its excellent thermo-chemical stability and high power conversion efficiency.
Despite the excellent performance, commercialization of CIGS solar cell technology has been
hindered due to issues related to the preparation of the absorber layer. The manufacturing of
CIGS absorbers needs innovative technological development to make them commercially
competitive, simplified and cost-effective. In this connection, the solution process utilizing
CIGS nanomaterial precursor is a non-vacuum, low-cost, non-toxic and scalable approach with
a high potential for developing an absorber layer. The typical processes comprise the synthesis
of high-quality CIGS nanomaterials followed by printing constituent precursors in thin film
form. Subsequently, thermal/photonic post-treatments of the printed precursors transform into
a high-quality photovoltaic-grade absorber. The chapter critically reviews CIGS nanomaterial
synthesis methods and discusses various printing techniques. The discussion follows an
investigation of printed thin film's thermal and photonic processing to realize a high-quality
CIGS absorber layer suitable for thin film photovoltaics. The processing parameters such as
annealing profile, post-treatment, annealing atmosphere, Selenium source, photonic fluences,
and alkali doping are discussed to understand their impact on the absorber's composition,
morphology, and optoelectronic properties. The findings and related reviews afford critical
insight into the absorber thin film design to improve the performance of solution-processed
chalcopyrite solar cells. Finally, current challenges and prospects for effective technology
implementation are discussed.

Published: July 2024

Tebing pasir vulkanik yang cukup curam tersusun dari deposit pasir tersementasi. Pasir tersementasi memiliki fabrik berongga, dimana partikel dan pengikat partikelnya saling mengunci oleh senyawa pengikatnya. Terlepas dari kekuatan tebing pasir vulkanik, keruntuhan pada tebing tersebut biasanya terjadi secara cepat dan tiba-tiba. Penelitian ini mengidentifikasi karakteristik kuat tekan pada model benda uji berupa pasir vulkanik dari longsoran tebing penambangan pasir Gunung Kelud dengan dilakukan serangkaian pengujian di laboratorium. Pengujian gradasi butiran, berat jenis, angka pori, identifikasi bentuk butiran, serta kuat tekan bebas pada model benda uji berdasarkan variasi waktu pemeraman dan waktu pengeringan yang telah ditentukan. Pasir yang diuji merupakan tanah berbutir dan bergradasi baik. Nilai Gs sedikit lebih tinggi dari pasir pada umumnya, karena partikel mikro menempel dan mengisi pori yang lebih besar, sehingga menimbulkan efek tegangan tarik permukaan antarbutiran dimana hal ini akan menambah kuat tekan tanah. Karena didominasi partikel bersudut, gaya friksi antarbutiran menjadi lebih besar dan meningkatkan gaya saling mengunci antarbutiran. Model benda uji diklasifikasikan tanah tersementasi lemah (qu < 30 kPa), dimana perlakuan terhadap waktu pemeraman tidak terlalu berpengaruh terhadap nilai qu. Nilai kadar air berpengaruh terhadap besarnya nilai qu. Keruntuhan benda uji terjadi secara tiba-tiba diawali dengan retakan menunjukkan benda uji memiliki sifat getas.

Published: July 2024

Construction 4.0 technology is an anticipation of the challenges of quality improvement in the construction industry. However, its implementation has not been simultaneous with an evaluation of the benefits and value of investment. For this reason, this research evaluates the benefits and investment feasibility of construction 4.0 technology on 36 projects of the Indonesian construction state-owned enterprise (SOE), PT. XYZ Persero Tbk. during 2020-2022 for Drones, Building Information Modeling (BIM) and Virtual Reality (VR) as individually and integrated. Based on evaluation data on the use of technology and financial data from technology investments obtained, this research quantitatively calculates the value of the benefits of increasing productivity and then calculates the financial evaluation using the Return on Investment (ROI), Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit-Cost Ratio (BCR) methods and implies those results qualitatively. As a result, individually, BIM is the technology that contributes the most in terms of benefits, VR contributes well in terms of investment value, while drones still have development potential. Integration between technologies is still challenging where the use of technology simultaneously does not guarantee significant integration between the three technologies reviewed in this research.

Data from the Rock Health Digital Health Consumer Adoption Survey collected from 2020 to 2022 with 23,974 US participants were analyzed. The sample was US Census–matched for demographics, including age, race/ethnicity, gender, and income. The relationship between sociodemographic factors and wearable ownership was explored using descriptive analysis and multivariate logistic regression.

Results

Of the 23,974 respondents, 10,679 (44.5%) owned wearables. Ownership was higher among younger individuals, those with higher incomes and education levels, and respondents living in urban areas. Compared to those aged 18-24 years, respondents 65 years and older had significantly lower odds of wearable ownership (odds ratio [OR] 0.18, 95% CI 0.16-0.21). Higher annual income (≥US $200,000; OR 2.27, 95% CI 2.01-2.57) and advanced degrees (OR 2.23, 95% CI 2.01-2.48) were strong predictors of ownership. Living in rural areas reduced ownership odds (OR 0.65, 95% CI 0.60-0.72). There was a notable difference in ownership based on gender and health insurance status. Women had slightly higher ownership odds than men (OR 1.10, 95% CI 1.04-1.17). Private insurance increased ownership odds (OR 1.28, 95% CI 1.17-1.40), whereas being uninsured (OR 0.41, 95% CI 0.36-0.47) or on Medicaid (OR 0.75, 95% CI 0.68-0.82) decreased the odds of ownership. Interestingly, minority groups such as non-Hispanic Black (OR 1.14, 95% CI 1.03-1.25) and Hispanic/Latine (OR 1.20, 95% CI 1.10-1.31) respondents showed slightly higher ownership odds than other racial/ethnic groups.

Conclusions

Our findings suggest that despite overall growth in wearable ownership, sociodemographic divides persist. The data indicate a need for equitable access strategies as wearables become integral to clinical and public health domains.

This study examines the information security awareness of university students, focusing on their knowledge, awareness, and practices related to smartphone usage. Using a 35-question survey, data were collected from 1364 students across six universities in China. Descriptive statistics, cross-analysis, and exploratory factor analysis were employed to assess students' security awareness levels. Results indicated that most students preferred Android, expressed concerns about personal finance and privacy risks, and primarily acquired security knowledge through internet media. Despite a satisfactory overall awareness, gaps were found in password setting and Wi-Fi connection practices. Male students performed better in knowledge and practice, while no significant differences were observed across grades. These insights are crucial for enhancing information security education programs.

Published: July 2024

The concepts of bacteriology are still poorly understood by students of the Department of Biology Education, Mulawarman University. Certain ethnic characteristics influence student learning processes and outcomes. A quasi-experiment was carried out at the Department of Biology Education, Mulawarman University in the even semester of the 2022/2023 academic year. The aim of the research was to map members of ethnic-based practicum groups in bacteriology practicum in an effort to empower understanding of bacteriology concepts. Ethnic-based practicum means that the practicum is carried out taking into account the ethnic diversity that exists in each group in the class. The research sample was class A and class B students who were taking a bacteriology practicum program. The research instruments were questionnaires and test questions. Data analysis techniques are percentage and covariance analysis. If there is a significant influence, then proceed with Least Significance analysis Difference. The results of data analysis show that there is a significant influence between the application of the product (a Project-Based Learning-based practicum guide) on understanding the concept of bacteriology as a result of development (p˂0.00). The research sample was class A and class B students who were taking a bacteriology practicum program. For further research, practical material needs to be supplemented with other bacteriological materials, and involve more ethnic types.

This study aimed to determine the difference in environmental literacy skills between the Project-Based Learning (PjBL) learning model and STEM-based PjBL. This research is quantitative research with a quasi-experimental method. The research design used is a non-equivalent pretest-posttest control group design. The dependent variable in this study is environmental literacy skills. The population in this study were all grade X students of State Senior High School (SHS) 7 of Surakarta in the 2023/2024 academic year. The sampling technique used was cluster random, tenth grade (X) A and B. A class consists of 36 students, as a control, using the PjBL model whereas as many as 35 students in B class is an experimental group was learned using the STEM-PjBL model. The data collection technique was carried out using pretest and posttest on the research sample. Data analysis technique using ANCOVA test. Instrument validation techniques using validity tests and reliability tests. The test results using ANCOVA have a significance value of <0.05, indicating differences in students' environmental literacy skills between the implementation of PjBL and STEM-PjBL. These results show that implementing the STEM-PjBL model was superior compared to PjBL only. It can be seen from the difference in learning outcomes of the control class, within the pretest and posttest, which showed an increase of 10.16%. In comparison, the experimental class results showed an increase of 16.94%. STEM-PjBL also helps students to be able to improve their environmental literacy skills in terms of knowledge, cognitive skills, attitudes, and behavior toward environmental problems.

The aim of this study was to analyze the corpus-based construction of the Indonesian Presidents’ speech at the UN. This research method used a descriptive approach. This type of qualitative research was oriented towards historical discourse analysis. This research data consisted of words, phrases, and sentences obtained from speeches by four Indonesian presidents at the UN. The data corpus of the four Indonesian presidents' speeches was obtained from the YouTube channel. The collection of corpus data in this research was carried out through observation to find out whether the videos of the four presidents' speeches were sound and complete. The available data corpus was analyzed based on Wodak's analysis of historical discourse (HDA). The research results indicated that the construction of the four Indonesian presidents’ speeches at the UN included the use of discursive strategies, namely argumentation and nomination. The findings of this research also showed that the argumentation strategy used topics that were divided into the past, present, and future. This topic refers to intrinsic topics in the form of reality, economy, justice, health and urgency, while extrinsic topics include reality, history, economics, threats, justice, health, and urgency. The nomination strategy found the use of personal deixis in the form of I, we, and us as identity markers in the Indonesian presidents’ speeches at the UN. The conclusion of this research indicated that the topic analysis and identity markers used by the four Indonesian presidents were different. This can be seen from the use of the number of words that appear in the four speech data corpus, which showed how the four presidents opened their talks and how they identified themselves, defined their countries, and described their attitudes.

Published: July 2024

The last decade has seen a shift in humanities research, including literature, both in terms of theory and methods. Literature is not only analyzed based on the sociology of literary works, but also the sociology of authors with multidisciplinary theories. Everyone has a position in the social arena on which to concentrate. His position can change from ordinary to extraordinary, Or vice versa. Trajectories can be seen as the result of contestation to obtain symbolic, economic, cultural and social capital. The aim of research on the trajectory of the Indonesian Muhammadiyah figure Nur Cholis Huda (NCH) is to analyze his habitus, capital and arena. This research uses Bourdieu's qualitative descriptive praxis theory. Data collection techniques were carried out through biographical narrative interviews and data validity through triangulation. The research results show that the NCH journey is influenced by : 1). Habitual literacy is acquired from school and does not come from the family structure. 2). The ability to utilize cultural capital and convert it into economic, social and symbolic capital, and 3). Habitus literacy plus strong cultural capital supports his success in competitions in the world of writing.Thus, to understand the success of an agent/figure in an arena, it is necessary to analyze its trajectory.
