Authors: Besli Eugenius
Published: February 2025

This study aims to examine the role of big data analytics as a moderating variable in the relationship between prudence and financial statement fraud. The research was conducted on Indonesian state-owned companies that went public in 2021-2023. Sample selection using purposive sampling technique. The research design uses descriptive quantitative with multiple linear regression analysis methods. Moderation variables are treated as quasi moderation variables and pure moderation variables. The test results show that prudence has a negative effect (-5.486 and -5.198) on financial statement fraud and is significant at the 10% level in the quasi-moderation model and significant at the 5% level in the pure moderation model. The higher the level of application of the principle of prudence the lower the chance of manipulative behavior. The moderating variable of big data analytics consistently has no effect on the research model either as a quasi-moderating variable or as a moderating variable. This is indicated by a significant value of 0.695 in the quasi-moderation model and 0.683 in the pure moderation model. The implementation of big data analytics in the form of software is still very low. The average use of software in state-owned companies going public only 1% of total assets. The low use of big data analytics causes no significant effect on the research model.

Published: February 2025

The high prevalence of gig workers in Indonesia and the preference for workplace flexibility among employees are significant concerns for companies, especially in human resource management. Therefore, this study focuses on job performance, hypothesized to be influenced by gig working and flexible working arrangements, mediated by work environment and work-life balance. The study population comprises all workers in Indonesia, with a sample of 120 respondents selected through purposive sampling. Data were analyzed using SEM-PLS methods. The findings indicate that both gig working and flexible working arrangements have a significant positive impact on employee performance in Indonesia. Gig working directly enhances performance, while flexible working arrangements influence performance through improved work environment and work-life balance. This suggests that the better the experience of gig working or perceived job flexibility among employees, the better their performance. This research can contribute to the improvement of job performance, emphasizing that employees are influenced by various factors in enhancing job performance. The findings of this study also provide practical contributions for companies regarding policies that need to be revised and established to improve job performance.

ABSTRACT
     The average development of palm cooking oil consumption at the household level in Indonesia for the 2015–2020 period shows an increase of 2.32% per year. Used cooking oil applied repeatedly will increase the level of free fatty acids (FFA), and the water content of the oil needs to be reduced to meet the quality standards of the Indonesian National Standard. Separating oil from FFA to meet the Indonesian National Standards (SNI) is generally carried out using a neutralization process, separation with a membrane, and purification using adsorbents. This research aimed to determine the ability of adsorbents to reduce free fatty acid levels from used cooking oil. Bentonite-chitosan and bentonite-chitosan-TiO2 were synthesized and then analyzed using FTIR, XRD, and SEM-EDX. Photodegradation was carried out with variations of adsorbent mass of 1.3 and 5g and time variations of 30, 90, and 180 minutes, and then free fatty acid levels were tested.The FTIR results showed the functional groups Si-O-Si, -OH, Si-O-Al, -CH2, -NH2, and TiO. The XRD analysis met the JCPDS standard data No. 21-1276 and  No. 21-1272. SEM analysis resulted in a clearer morphology, such as chunks that were uneven in size, smooth, and layered. The free fatty acid content obtained the best results of 9.51% at the adsorbent mass of 1 g with a time of 90 minutes

Published: February 2025

Syzygium samarangense mengandung senyawa flavonoid telah terbukti bermanfaat. Penelitian sebelumnya mengungkapkan bahwa aurentiacin, pinocembrin, stercurensin, dan uvangoletin sebagai bahan kimia bioaktif terdapat pada kulit batang tanaman. Senyawa ini terbukti memiliki aktivitas antioksidan yang sangat baik. Namun, belum ada penelitian mengenai potensinya sebagai agen anti melasma dan anti jerawat. Penelitian ini berupaya melihat keempat bahan kimia tersebut berpotensi sebagai penghambat tyrosinase (TYRP1) anti melasma dan penghambat androgen (AR) anti jerawat dengan menggunakan teknologi biokomputasi. Studi ini mencakup analisis druglikeness Lipinski dan molecular docking menggunakan protein TYRP1 dan AR dengan hidrokuinon dan clascoterone sebagai obat kontrol. Analisis lebih lanjut dilakukan dengan prediksi PASS-Online untuk mendukung potensi senyawa. Hasilnya menunjukkan bahwa semua senyawa berpotensi menjadi agen anti melasma dan anti jerawat yang efektif, dengan pinocembrin (-7.4 kkal/mol untuk TYRP1; -8.8 kkal/mol untuk AR) menjadi senyawa yang paling manjur. Senyawa ini memenuhi aturan kemiripan obat Lipinski dan didukung oleh prediksi PASSOnline bahwa senyawa tersebut berpotensi sebagai pemutih kulit dan antagonis androgen. Namun, penelitian lebih lanjut, termasuk penelitian in vitro dan in vivo, diperlukan untuk memastikan potensinya sebagai agen anti melasma dan anti jerawat.

ABSTRACT
      Syzygium samarangense containing flavonoid compounds have been proven to be beneficial. Previous research revealed that the aurentiacin, pinocembrin, stercurensin, and uvangoletin as bioactive chemicals were present in the plant stem bark. These compounds have been found to have excellent antioxidant activity. However, there has been no research on their potential as anti-melasma and anti-acne agents. This research attempts to look into these four chemicals potential as anti-melasma tyrosinase inhibitors and anti-acne androgen inhibitors using biocomputation technology. The study included druglikeness and molecular docking analyses using TYRP1 and AR proteins with hydroquinone and clascoterone as control drugs. Further analysis was carried out with PASS-Online predictions to support the potency of compounds. The results indicated that all compounds have the potential to be effective anti-melasma and anti-acne agents, with pinocembrin (-7.4 kcal/mol for TYRP1; -8.8 kcal/mol for AR) being the most potent compound. These compounds fulfilled Lipinski's druglikeness rules and were supported by PASSOnline's predictions that they have potential as skin whiteners and androgen antagonists. However, further research, including in vitro and in vivo studies, is necessary to confirm their potential as anti-melasma and anti-acne agents.

Published: February 2025

Objective: To analyze the epidemiological situation of oral health in five-year-old schoolchildren in public schools in the municipality of Foz do Iguaçu, Paraná, Brazil, considering sociodemographic markers and place of residence.
 
Theoretical Framework: Studies have revealed a significant reduction in the prevalence of dental caries in the general Brazilian population. However, dental caries in schoolchildren continues to be a challenge to overcome due to its high prevalence.
 
Method: This is a quantitative, cross-sectional study. Between September and November 2022, 395 schoolchildren were evaluated, selected from a random sample considering the number of students per school and health district. Information on the sociodemographic profile was collected from enrollment records. The dental examination was performed by trained dentists (inter-rater agreement had a Kappa coefficient of 0.90). Chi-square and ANOVA tests were used to analyze and compare the indicators.
 
Results and Discussion: Of the sample evaluated, 48.6% of the children had at least one cavity (mean 1.67; standard deviation 2.55), resulting in a ceo-d index of 2.06. The ceo-d mean was associated with the shift, while the proportion was associated with the health district and race/skin color.
 
Research Implications: This study reflects the persistence of a health problem, which proved to be highly prevalent in children. These findings are important for the fields of dentistry and health management.
 
Originality/Value: This study contributes to the literature by highlighting an important oral health indicator that is not always disseminated or analyzed at the local level. This study advances by contributing with an analysis methodology that allows the distinction of the phenomenon within the municipality itself.

Как во Владивостоке «ориентализм» открыли
Authors: КУЗНЕЦОВ Анатолий Михайлович
Published: February 2025

В статье проведено сопоставление основных положений концепции ориентализма Э. Саида и теории этноса С.М. Широкогорова. Основанием для проведения такого сравнительного исследования стал тот факт, что оба исследователя учитывали взаимосвязь ученого, специалиста, дипломата, путешественника, автора и читателя с окружающей средой. У Саида это отношение было выражено через понятие ориентализм («обмирщённость»), у С.М. Широкогорова – через психоментальный комплекс как составной части его теории этноса. При этом важно отметить, что российский учёный сформулировал проблему влияния конкретных условий среды на связанных с ней людей ещё в 1920–1930-е гг. во время его пребывания во Владивостоке и в Китае. О значении идей С.М. Широкогорова и Э. Саида наглядно свидетельствует тот факт, что их идеи сегодня получают развитие в рамках трансдисциплинарного подхода и энактивистского направления.

The article compares the main provisions of the concept of Orientalism by E. Said and the theory of ethnicity by S.M. Shirokogorova. The basis for conducting such a comparative study was the fact that both researchers took into account the relationship of the scientist, specialist, diplomat, traveler, author and reader with the environment. In Said, this attitude was expressed through the concept of orientalism ("worldliness"), by S.M. Shirokogorov – the concept of psychomental complex as an integral part of his theory of ethnos. It is important to note that the Russian scientist formulated the problem of the influence of specific environmental conditions on people associated with it back in the 1920-1930s during his stay in Vladivostok and China. On the meaning of S.M.’s ideas Shirokogorov and E. Said is clearly evidenced by the fact that their ideas today are being developed within the framework of a transdisciplinary approach and an enactivist direction.
Механизмы экономического сотрудничества стран Северо-Восточной Азии
Authors: ИЗОТОВ Дмитрий Александрович

Показаны механизмы торгового и инвестиционного сотрудничества в Северо-Восточной Азии (СВА). Определены сложности в создании трёхстороннего интеграционного формата между странами Большой тройки СВА, вызванные отсутствием консенсуса между Японией с одной стороны и Китаем с Республикой Корея – с другой. При этом страны Большой тройки СВА значительно продвинулись в снижении барьеров инвестиционного сотрудничества. Выявлено, что Республика Корея занимала наиболее активную позицию по расширению интеграционных форматов с зарубежными странами, имея доступ практически ко всем крупнейшим рынкам мира. Указаны причины недостаточной мотивации у российской и монгольской сторон для снижения барьеров со странами СВА, а также специфичные черты экономики КНДР, препятствующие расширению международного торгового и инвестиционного сотрудничества.

The mechanisms of trade and investment interaction in North-East Asia (NEA) are shown. The difficulties in creating CJK FTA between the have been identified, caused by the lack of consensus between Japan on the one hand and China and the Republic of Korea on the other. At the same time, Japan, China and the Republic of Korea have made significant progress in reducing barriers to investment integration. It was revealed that the Republic of Korea was very active in creating integration formats with foreign countries to access the world's largest markets. The reasons for the lack of motivation for Russia and Mongolia to reduce barriers with the NEA countries are indicated. The specifics of the DPRK economy, which hinder the expansion of international trade and investment cooperation, are shown.

Published: February 2025

Subject. Under the impact of exogenous shocks (sanctions, trade wars, etc.), the Russian economy faces intensifying processes of structural deindustrialization and technological primitivization of industrial production. Monoprofile regions, including the Kemerovo Oblast–Kuzbass, demonstrate particular vulnerability. Such challenges become "points of no return", requiring deep changes and stabilization of the main macroeconomic indicators from the current inertial structure of the regional economy.
Objectives. The purpose is to underpin the main essential forces that have a key impact on the structural dynamics of the economy of the producing region.
Methods. The article presents an assessment of structural and technological development of the Kemerovo Oblast–Kuzbass, based on the indicator approach. The empirical basis of the study was Rosstat data and the data from Russian information and analytical agencies.
Results. The measures implemented at the regional government level to structurally transform the economy of the Kemerovo Oblast–Kuzbass and protect key market participants from negative effects of external shocks are significant, but insufficient to achieve a long-term stabilization. The analysis of dynamics of indicators characterizing the structural and technological development of the economy of the said area demonstrates its high vulnerability to external shocks. At the same time, relative to all-Russian trends, regional processes are deeper and more acute.
Conclusions. Given the nature and severity of structural problems specific to the presented types of regions, the determinants of structural transformation of the extractive region’s economy are investments, technologies, institutions, and social groups.
