Authors: Amalina Amalina , Samat N.A , Warmansyah Jhoni
Published: February 2025

This study aims to identify the influence of smartphone usage duration and frequency on smartphone addiction in early childhood. With the increasing use of technology among children, it is crucial to understand how these factors affect addiction levels. The study employs binary logistic regression to analyze data collected randomly from 100 parents of children aged 4 to 5 years who attend kindergarten in Padang, Indonesia. Smartphone usage duration is measured in hours per day, while frequency of use is measured by the number of uses per day. The analysis results indicate that both the duration and frequency of smartphone use have a significant impact on smartphone addiction. However, based on the odds ratio value, the duration of smartphone use has a more significant influence compared to frequency on addiction levels. These findings provide valuable insights for parents, educators, and policymakers in developing strategies to manage and limit smartphone use in early childhood to prevent addiction risks that could affect their development. This study is expected to serve as a reference for further research and more effective interventions in managing technology use among children.

Munawatul Khair Arabic School is one of the madrasah that played pivotal role in the history of Islamic education in Lampung during 1930-1950. This madrasah began in Tanjung Agugn, Bengkulu in 1925, founded by K.H. Hosen bin Abd Syukur. The madrasah is centered in Tanjung Karang, Bandar Lampung in 1930. This study is a form of literature research using historical and philosophical approach. The data source was collected from primary and secondary data. Primary data of this study is based on the records of the madrasah. While secondary data was similar researches from other researchers. This research used historical method, (1) Heuristic: data collection from primary and secondary data, (2) Criticism source, related criticism given internally or externally, (3) Interpretation involves combining various data sources to interpret a study, (4) Historiography, the historian’s endeavor to reconstruct a history by writing it into a research.The result of this study aims to enrich the value of education history, especially Islamic education in Lampung, focusing on the significant role of Madrasah Munawatul Khair Arabic School as a leading institutionof its time. Little history is yet to be discovered regarding education in Lampung, specifically detailing the development of education in Lampung. The establishment of Munawatul Khair Arabic School in Lampung and Bengkulu provided Islamic education for the indigenous people of Indonesia. This action was particularly significant given the limited access to Islamic education during the colonial and post-colonial eras. While little impact this madrasah had provided globally, its influence was felt locally, especially among marginalized communities who had limited access to government-run schools during that period.

Флористическая и анималистическая метафора в российском публицистическом дискурсе 2022–2023 гг.
Authors: Громенко Е. С.
Published: February 2025

В статье проведен анализ актуализированных в российском медийном дискурсе 2022–2023 гг. наи-менований, ассоциативно связанных с военной техникой, используемых в СВО. Актуальность исследования фитонимических и анималистических метафор определяется, во-пер-вых, тем, что метафорические номинации растительного мира играют одну из важнейших ролей в нашей жизни и находит своеобразное отражение в системе знаний человека. Во-вторых, такие метафоры регулярно используются в политическом дискурсе, языке СМИ. Кроме того, важность исследования метафорических номинаций определяется тем, что метафора помогает передать ин-формацию, которую автор по тем или иным причинам не считает возможным обозначить прямо, при помощи непосредственных номинаций.

Цель исследования – проследить развитие новых значений у флористической и анималистиче-ской лексики в контексте военных действий новейшего периода. Материалом исследования послу-жили обнаруженные в текстах массмедиа 2022 года семантические неологизмы, областью-источни-ком метафорического переноса которых являются номинации, так или иначе связанные с миром растений и животных. Кроме того, эта группа лексики также была ограничена областью цели мета-форического переноса – сферой вооружения.

В медийном дискурсе 2022 году произошла активизация и актуализация анималистической метафоры, обусловленная темой используемого Украиной вооружения НАТО (FV430 «Bulldog», «Wolfhound», «Dingo ATF», «COBRA», «Cougar», «Leopard 2A6», «Leopard-1A5s», «Mastiff», «Lynx», «Husky»). Совокупность номинаций натовской военной техники, отсылающих к представителям различных животных становится поводом для обыгрывания этой группы лексики. Одной из самых частотных метафорических реализаций этой языковой ассоциации становятся номинации зоопарк и зверинец.

Принцип наименования единиц российской военной техники через названия цветов (САУ 2С3 «Акация», 2Б9 «Василек», САУ «Гвоздика», БПЛА «Герань-2», САУ 2С5 «Гиацинт», 2С7 «Пион», 2С4 «Тюльпан», 9П157 «Хризантема-С»)) послужил в российском медийном пространстве в 2022 г. ос-новой для ассоциативной реализации флористической метафоры разного уровня. В отношении к видам вооружения Российской Федерации в 2022 году в СМИ, его использованию начинает широ-ко употребляться флористическая лексика, представленная такими, например, существительными, как букет, геранька, рассада, росток, цветник, цветок; прилагательными гераневый, геранеподоб-ный, цветочный; глаголами распускаться, расти, расцветать, цвести.

Представляется, что использование авторами текстов СМИ невоинственной, заведомо неагрес-сивной флористической лексики для описания военного столкновения между Россией и Украиной, а также избегание возможных агрессивных анималистических метафор при описании стороны противника был сделан для смягчения военного дискурса, для снижения уровня напряжения при помощи образных описаний, адресатом которых является гражданское население.
GESTALT ALGI İLE EN İYİ FİLM DALINDA ÖDÜL ALMIŞ YAPIMLARIN AFİŞ ÇÖZÜMLEMESİ
Authors: Orkan Serra
Published: February 2025

Görsel kültür içerisinde yer alan medya araçlarından biri de afiştir. Günümüz afişlerinde fotoğraf ve baskı teknolojilerinin izleri vardır. Ayrıca filmi en iyi şekilde yansıttığı düşünülen göstergeler yer almaktadır. Tüketici ile iletişim kurarken afişteki amaç öncelikle dikkat çekmek, eğitmek, teşvik etmek, ikna etmek vb. niyetlerle oluşturulan eylemlerdir. Renk, şekil, tipografi ve düzen unsurları ile bir afişin genel olarak değerlendirilmesi mümkündür. Multidisipliner bir yöntem olan Gestalt prensipleri ile biçimsel ve içerik anlamlandırma süreci daha kolay ve doğru ilerleyebilmektedir. Bu sebeple çalışmada yöntem olarak Gestalt algı prensipleri ile çözümlemeden yararlanılmıştır ve 2019 senesinden itibaren her yıl en iyi film Oscar ödülünü almış yapımların afiş çözümlemesi yapılmıştır. Afişlerin tamamı şekil-zemin ilişkisine göre değerlendirilebilmiş; ancak tüm Gestalt prensipleri afişlerin hepsinde gözlemlenmemiştir. Bilimkurgu unsurlarının yer aldığı film afişlerinde efekt ve illüstrasyondan yararlanılmış, dram türünü yansıtan filmlerde, afişlerde tek fotoğraf karesi ile içerik aktarılmıştır. Afişler; Gestalt algı prensibi olan “bütün parçalar toplamından başka ve daha fazla bir şeydir.” savını da desteklemektedir.
RUSÇADAN BAŞKURTÇAYA GEÇEN SÖZCÜKLERDE GÖRÜLEN FONETİK DEĞİŞİMLER
Authors: Tay Sevilay
Published: February 2025

Bu çalışmada, Başkurt şair ve yazar Zeyneb Biişeva’nın Kämhetelgändär romanından ve Başqort Teleneñ Hüẕlege I-II adlı sözlükten tespit ettiğimiz Rusça alıntı sözcüklerde görülen fonetik değişimleri inceledik. Çalışma, Başkurt Türkçesine geçen Rusça alıntı sözcüklerin, Rusçanın gramer kurallarından ve fonetik özelliklerinden ne denli farklılaştığını ve bunları ne düzeyde koruduğunu tespit etmeyi amaçlamaktadır.Dilsel ilişkiler yönünden bakıldığında, kaynak dilden geçen alıntı sözcüklerin birçoğunun alıcı dilin morfolojik, fonetik ve gramatik kurallarına uyum sağladığı görülür. Bunu yaparken de kimi zaman sözcükler anlam genişlemesine, anlam daralmasına veya çok anlamlılığa evrilebilir. Öyle ki, bu çalışmadaki bazı alıntı sözcüklerde de bu durum dikkatimizi çekmiştir, ancak burada fonetik bir inceleme söz konusu edildiğinden semantik inceleme yapılmayacaktır. Bu çalışmada, ünlü ve ünsüzlerin durumunu ve ses olaylarını incelerken şu yöntemler kullanılmıştır: Başkurt Türkçesindeki ünlü ve ünsüzlerle ilgili kısaca bilgiler aktarıldıktan sonra, alıntı sözcüklerle ilgili ses değişimlerine geçilmiştir. Sözcüklerin Başkurt Türkçesinde transkripsiyon harfleriyle yazılışı ve parantez içerisinde romanın kısaltması ile sözcüğün geçtiği sayfa numarası verilmiştir. Ardından, çift tırnak içerisinde kelimenin Türkçe karşılığı ve parantez içerisinde, kullanılan sözlük kısaltması ile sayfa numarası yer almıştır. Aynı yöntem sözcüğün Rusçası için de uygulanmıştır.Sonuç olarak, Rusçadan Başkurt Türkçesine geçen 92 adet alıntı sözcüğün fonetik olarak incelendiği bu çalışmada, çoğunlukla ünlülerin değişime uğradığı tespit edilmiştir. Aynı zamanda, bu değişimlerin sıklıkla ilk ve orta hecelerde meydana geldiği görülmüştür. Başkurt Türkçesinin, alıntı sözcüklere kendi fonetik kurallarını yoğun biçimde uygulaması, bu dilin alıntı sözcüklere olan pozitif tutumuyla ilgili olarak da fikir vermektedir. Öyle ki, Başkurt Türkçesi hem kendi gramer özelliklerini hem de Eski Türkçenin temel özelliklerini uygulama ve muhafaza etme temayülü göstermektedir.
Antibacterial Effect of Phenylboronic Acid on Escherichia coli and Its Potential Role as a Decontaminant of Fresh Tomato Fruits

Published: February 2025

Research background. Food safety is threatened by the contamination of fresh fruits and vegetables by pathogenic bacteria, among which the particularly widespread ones are coliform bacteria. Due to the continuous increase in the incidence of severe diseases caused by the consumption of fresh (tomato) fruits contaminated with Escherichia coli, antimicrobial postharvest measures are needed. The problem is that many active antimicrobial compounds have a weak and short-lasting effect and/or are not environmentally friendly. Recently, the antibacterial and antifungal activity of environmentally friendly agent phenylboronic acid (PBA), including on a couple of tomato pathogens, was reported.
Experimental approach. This study aimed to determine the antibacterial effect of PBA on E. coli and three enteropathogenic Enterobacterales, and to check its ability to serve as a bacterial decontaminant of fresh tomato fruits.
Results and conclusions. The minimal inhibitory concentration (MIC) of PBA against E. coli, as well as Shigella sonnei, Salmonella enteritidis, and Yersinia enterocolitica were 1.0, 1.2, 1.0 and 0.8 mg/mL, respectively. Moreover, we have shown that PBA has a bacteriostatic effect on E. coli at lower concentrations and a bactericidal effect at higher (>3.0 mg/mL) concentrations. Importantly, the study found that an E. coli strain resistant to seven commonly used antibiotics, as well as strains producing extended-spectrum beta-lactamases (ESBL), is as sensitive to PBA as the wild-type strain lacking any resistance, suggesting that PBA’s mechanism of action differs from that of all these antibiotics. Finally, we have shown that washing and incubating contaminated tomato fruits in PBA solution reduces the growth of E. coli washed from fresh tomato fruits in a dose- (0.5–3.0 mg/mL) and time-dependent manner, while having no adverse effect on the tomato fruits.
Novelty and scientific contribution. This is the first report of PBA’s antibacterial effect on medically important bacteria E. coli, S. enteritidis, S. sonnei and Y. enterocolitica. Moreover, we show that PBA kills multiple-antibiotic resistant E. coli, including those producing ESBL, revealing it as a promising agent against such bacteria. Finally, PBA is shown to be an effective decontaminant of E. coli on fresh tomato fruits.
Supported Employment for people with mental disabilities in South Africa: cost calculation of service utilisation
Authors: Engelbrecht Madri , Van Niekerk Lana , Coetzee Zelda , Hajwani Zerina
Published: February 2025

Introduction: Supported Employment (SE) is a strategy that facilitates positive employment outcomes for people with mental disabilities in open labour market settings. SE's cost-effectiveness has been established internationally, but not in South Africa. This paper reports on the cost and affordability of SE services offered to people with mental disabilities in South Africa.Method: A longitudinal descriptive study was used to determine the cost of SE service components utilised by people with mental disabilities, from two programmes in the Western Cape. The utilisation of service elements was captured in 15-minute time units. Data collection continued for 12 months, commencing when a job had been identified and preparation for placement had ensued. Time utilisation data were used to calculate cost, using a government sessional salary (R189/hour) and a medical aid reimbursement rate (R367/hour) of occupational therapists acting as job coaches.Findings: The findings show SE services to be less than 10% of the cost of a monthly disability grant, and 10% - 21% lower than the current subsidy per consumer in a protective workshop.Conclusion: Evidence from the study thus reflects the cost of SE services to people with mental disability as substantially lower than the current government investment in disability grants and protective workshops subsidies.Â Key words: psychiatric disability; intellectual disability; vocational rehabilitation; reasonable accommodation; return to work
"We all need employment" - An exploration of the factors which influence the return to work after a severe traumatic brain injury

Published: February 2025

Introduction: While individuals with mild and moderate traumatic brain injury (TBI) manage to achieve some degree of successful return-to-work, individuals with severe TBI have a reduced chance of returning to work. This study aimed at investigating how personal factors, workplace environment and vocational rehabilitation influenced the return-to-work and assumption of the worker role of individuals with severe TBI.Method: A phenomenographic study design with purposive sampling was used to select 11 participants. Data were collected through semi-structured interviews using the Worker Role Interview as a guide. Data were thematically analysed using Clarke and Braun's six phases of thematic analysis.Results: Two themes emerged: It's all about me, which addressed the internal aspects of the role of a worker and The support for me which focused the external factors of personal, work and rehabilitative support.Conclusion: Results showed that rehabilitation, personal factors and work support were critical for successful return-to-work for survivors of severe TBI. Results indicated that participation in work was as important in developing self-worth as participation in any other area of daily living. With regard to personal factors, rehabilitation and support were vital in maintaining self-worth after an injury. This could be enhanced through vocational rehabilitation.

A STEADY-STATE BEHAVIOUR OF AN M/M/1 QUEUE WITH OPTIONAL DIFFERENTIATED WORKING VACATIONS, SERVER BREAKDOWN, AND CUSTOMER BALKING
Authors: Muthukumar S. , Bagyam J. Ebenesar Anna
Published: February 2025

This paper analyses the steady-state behaviour of an queueing system incorporating optional differentiated working vacations, server breakdowns, and customer balking. Following a busy period, the server might transition into an optional I or II working vacation, leading to a reduction in the service rate. Customers may balk when the server is on vacation or experiencing a breakdown. The model’s stable solution is derived using probability-generating functions, enabling the evaluation of key performance metrics. A cost optimization framework is employed to minimize the cost by balancing system parameters. Numerical examples demonstrate the impact of varying arrival and service rates on customer queue length and waiting times.
Semiotic analysis of visual images in modern Ukrainian social posters
Authors:   Beketov National University of Urban Economy in Kharkiv, Kharkiv, Ukraine, Sosnytskyi Yurii
Published: February 2025

Background. The article examines the role of contemporary Ukrainian social posters as a powerful tool of visual communication that not only shapes national identity but also conveys contemporary social values. In particular, it analyzes how visual strategies, compositional solutions, and the use of archetypes contribute to influencing public consciousness. Special attention is given to exploring posters as a cultural phenomenon that reflects socio-political processes and cultural dynamics in Ukraine through symbols and images. The study emphasizes the significance of social posters as a means of strengthening social cohesion and national spirit.

Methods. The research adopts a comprehensive approach that integrates several methodologies. Semiotic analysis was employed to uncover the multilayered meanings of symbols and visual images in social posters, designed to establish an emotional connection with the audience. Content analysis of poster archetypes identified key images that have the most significant impact on viewers. Visual analysis was used to explore the compositional, coloristic, and aesthetic decisions that ensure the effectiveness of posters in audience perception. Each method contributed to revealing the specifics of the visual language of Ukrainian social posters.

Results. The findings indicate that contemporary Ukrainian social posters exhibit high aesthetic and communicative effectiveness through the thoughtful integration of visual and semantic elements. Artistic and expressive principles, such as the use of symbolism, typography, and color schemes, enhance the emotional impact of posters. Particular attention is drawn to psychological methods employed to shape public opinion and mobilize viewers. The study also highlights the active use of visual archetypes, such as the "hero," "defender," "mother," "home," and "land," which are integral to national and cultural identity. Persistent stereotypes, rooted in collective perceptions and cultural codes, further amplify communication effectiveness.

Conclusions. Based on the conducted analysis, it can be concluded that contemporary Ukrainian social posters are a vital component of cultural discourse, effectively combining emotional and rational influences on the audience. The use of archetypes and symbols ensures a deep emotional connection with viewers, fostering national identity, shaping civic awareness, and stimulating social dynamics. Social posters in Ukraine demonstrate substantial impact through the integration of visual and semiotic elements, making them universal tools of communication and influence.

Robotic Additive Manufacturing (RAM) represents an innovative approach to 3D printing, utilizing multi-axis industrial robots to execute complex printing tasks. This study focuses on path planning and the investigation of key parameters affecting the print quality of thin-walled tubes printed using a planar method. The experiments analyzed the effects of cooling, robot movement speed, material feed rate, and the number of perimeter layers on print quality. The results indicate that the combination of these parameters influences the quality and overall success of the printing process. Path generation was based on G-code created in open-source slicers, which was adapted for the ABB IRB 120 industrial robot. Future research will focus on expanding the study to the printing of non-planar curved tubes.
Comparative analysis of the outcomes of high tibial osteotomy performed with different techniques
Authors: Magomedov M. Sh. , Chugaev D. V. , Kulyaba T. A. , Petukhov A. I.
Published: February 2025

Introduction Opening- and closing wedge osteotomies are the two most commonly used variants of high tibial osteotomy in medial gonarthrosis associated with varus deformity.

Purpose Based on a retrospective analysis of the results of surgical treatment of patients with medial gonarthrosis associated with varus deformity of the proximal tibia, to evaluate functional and radiological outcomes of high tibial osteotomy performed with two different surgical techniques.

Material and methods The study included 37 patients (26 men and 11 women) aged 20 to 54 years (42.84 ± 9.1) with meadial gonarthrosis associated with varus deformity in the frontal plane. The first group included 23 patients with 25 operated limbs who underwent open wedge osteotomy (OWO), the second group included 14 patients who underwent closed wedge osteotomy (CWO).

Results Comparison of MPTA, LDTA, aPPTA and MAD in both groups after surgery did not show a statistically significant difference (p > 0.05), but in the closing wedge group, the recorded values had an extremely wide range. The results on the Lisholm-Tegner scale after surgery compared between the two groups showed a statistically significant difference (p = 0.05), this parameter showed that the opening-wedge osteotomy was more effective.

Discussion Opening wedge osteotomy is a more predictable surgical procedure compared to closing wedge osteotomy. In opening wedge osteotomy, there are significantly fewer cases with excessive or insufficient correction of reference angles and lines than after closing wedge osteotomy.

Conclusion Absence of specific surgical complications in the studied patients demonstrates the safety of  both surgical techniques. The study showed an extremely wide range of MPTA and LDTA values in the closed wedge osteotomy group, which were beyond the preoperative planning. The CWO group had the highest number of patients who underwent hypercorrection of the mechanical limb axis, which was beyond the reference values. It is possible to use a small allograft or not to use it at all in OWO, which makes it a more manageable technology for correcting limb bone deformity.

Published: February 2025

Introduction Elevated concentrations of serum calprotectin and lactoferrin were observed to make prediction about microvascular changes in patients with bone fractures.

The aim of the present study was to assess the diagnostic value of serum calprotectin and lactoferrin in the development of inflammatory response in patients with bone fractures.

Material and Methods Seventy patients were included in the study between October 2021 and January 2022; of these, 40 had bone fractures and 30 were healthy participants (control group). Calprotectin and lactoferrin were measured by immunosorbent assay.

Results 12 patients (30 %) had open bone fractures while 28 (70 %) had closed bone fractures. The study revealed that levels of serum calprotectin significantly increased in patients with bone fractures as compared to healthy subjects, while lactoferrin exhibited a borderline but not significant increase (P = 0.06). Patients with open bone fractures had higher levels of serum calprotectin compared to those with closed fractures (P = 0.05). The correlation matrix exhibited that there was a strong positive correlation between calprotectin and lactoferrin in patients with bone fractures.

Discussion Calprotectin is classified as a potent pro-inflammatory marker that has been noted to be elevated in  chronic inflammation such as irritable bowel syndrome (IBS), atherosclerotic lesions, different types of arthritis, and immunological rejection. The present study may only confirm an increase in calprotectin in patients with bone fractures. Recently published studies indicate the potential new role of calprotectin in bone healing and fracture risk.

Conclusion High serum calprotectin and lactoferrin indicate a strong inflammatory status in bone fracture patients, especially in those with open fractures.
Scaphoid nonunion and SNAC treatment
Authors: Shchudlo N. A. , Kuttygul Sh. K.
Published: February 2025

Introduction Scaphoid nonunion can result in progressive scaphoid nonunion advanced collapse (SNAC) and  have an impact on the quality of life in younger patients. The social significance of the pathological condition induces original research and literature analysis.

The objective was to identify methods for preventing scaphoid nonunion and improving treatment outcomes for SNAC patients based on the literature on etiology, diagnosis and treatment of the disease.

Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www.elibrary.ru) and the National Library of Medicine (www.pubmed.org) and using the  keywords: scaphoid nonunion, scaphoid, bone grafting, scaphoid nonunion, vascularized bone graft. The  search yielded 355 results. Literature searches included both Russian and English studies published between 1984 and 2024. Inclusion criteria included original articles, systematic reviews, meta-analyses relevant to the search topic. Non-inclusion criteria included a case report, case/control, and articles available only on a fee-paying basis. There were 67 articles identified.

Results and discussion The topography of the scaphoid is associated with a high incidence of avascular necrosis, delayed healing and fracture nonunion. Clinical testing and imaging are essential for diagnosis of scaphoid fractures in the acute period of injury, and fracture instability would be important for surgical indications. There is a classification of scaphoid nonunions that is practical for the choice of a surgical treatment (osteosynthesis with compression screws, debridement and bone grafts or “salvage” operations). Scaphoid nonunions treated with the Ilizarov method employing no open approaches or grafts was reported in  a few publications. Treatment of SNAC patients is traditionally based on the stage of the disease: 1 —  scaphoid reconstruction, resection of the styloid process of the radius; 2–3 — 4-corner arthrodesis or the proximal row carpectomy. Meta-analyses highlight the need for the research into the effectiveness of  various treatments. Arthroscopic techniques are common in wrist surgery improving diagnostic capabilities and minimally invasive interventions.

Conclusion Timely healing of a scaphoid fracture is essential for preventing carpal instability and SNAC. The choice of SNAC treatment is associated with the stage of the disease and functional needs of the patient.

Published: February 2025

Research aims: This research aims to analyze the flypaper effect on regencies and municipalities in Indonesia, considering the medium-term expenditure framework and their economic conditions.Design/Methodology/Approach: Quantitative methodology with secondary data from 226 regencies/municipalities in Indonesia was used. The first hypothesis testing was to find whether there was a different expenditure mean value, and if there were any, hypothesis testing about flypaper occurrence would be performed.Research findings: The results show that there was no difference in capital expenditure mean value because there was a target of capital expenditure set for every local government. Therefore, flypaper effect occurrence hypothesis testing was not performed, and there was different operational expenditure mean values. The flypaper effect did not occur in rich local governments but in poor ones.Theoretical contribution/Originality: This research fills the research gap of flypaper effect occurrence on capital expenditure and operational expenditure based on local governments’ economic conditions.Practitioner/Policy implication: This research implies that intergovernmental transfers should be used accordingly, and local governments should increase their local own-source revenue so that they wouldn’t be dependent on the transfers from the central government.Research limitation/Implication: The limitations of this study were related to the data period (abnormal condition of COVID-19) and statistical data (further explanation from primary data needed).

Published: February 2025

Latar Belakang: Perusahaan atau manajemen menjalankan suatu tindakan yang mampu membuat pelaporan keuangan perusahaan terlihat bagus, atau bisa dikatakan perusahaan memanipulasi laba agar perusahaan berjalan dengan baik, dan dapat menarik perhatian pihak luar. Pada riset ini manajemen laba riil dengan proksi independen diusulkan sebagai variable moderasi untuk mengetahui apakah dewan suatu perusahaan dapat mengarahkan perusahaan dan melaksanakan pemantauan kinerja manajemen
Tujuan: Untuk memberikan gambaran apakah perusahaan melakukan manajemen laba riil atau melakukan manipulasi laba melalui aktivitas kas operasi dan menurunkan harga pokok penjualan untuk meningkatkan angka laba, juga untuk mengetahui apakah fungsi monitoring dewan komisaris berjalan dengan sebagai mana mestinya.
Metode Penelitian: Populasi yang digunakan adalah perusahaan manufaktur yang menerbitkan laporan keuangan pada periode 2020-2022. Penelitian ini menggunakan uji linier berganda untuk menjawab hipotesis yang diajukan.
Hasil Penelitian: Hasil penelitian ini menunjukkan bahwa ukuran perusahaan berpengaruh signifikan negatif terhadap manajemen laba riil, sementara leverage, pengungkapan sukarela, dan arus kas bebas tidak menunjukkan pengaruh signifikan terhadap manajemen laba riil. Selain itu, kepemilikan manajerial (sebagai moderator) hanya sedikit memoderasi hubungan antara ukuran perusahaan dan manajemen laba riil, namun tidak memoderasi variabel lainnya secara signifikan.
Keaslian/Kebaruan Penelitian: Paper ini memberikan penyegaran atas isu krusial bahwa manajemen laba riil dapat diatasi apabila dewan komisaris independen menjalankan tugasnya.

Background: Efficient utilization of anticancer agents is crucial for effective malignancy treatment and cost management. WHO Prescribing Indicators provide a standardized measure for assessing drug usage. This study aimed to evaluate anticancer drug utilization patterns in a specialized oncology hospital using these indicators.
Methods: A cross-sectional analysis involved reviewing medical records of anticancer drug prescriptions at a designated cancer treatment facility. Key WHO prescribing indicators, including drug per prescription average, proportions of anticancer drugs and generics usage, were assessed.
Results: Analysis of 900 prescriptions revealed an average of 8.36 drugs per prescription, with 2.27 being anticancer drugs and 4.93 adjuvants. Notably, 71% of medications were prescribed generically 85% were on the Essential Medicines List. Opportunities for enhancing efficiency, like promoting generic drugs and reducing injectable anticancer agents, were identified.
Conclusions: This study highlights the value of WHO Prescribing Indicators in analysing anticancer drug utilization trends. Addressing prescribing deficiencies can refine treatment protocols, promote judicious pharmaceutical use and elevate patient care standards. Future efforts should focus on targeted strategies to rectify these shortcomings, emphasizing ongoing research and quality improvement in oncologic pharmacotherapy.

Background: Krishna Chaturmukha (KMC) is an ayurvedic formulation predominantly used as a traditional medicine in the rural population to get relief from various neurological disorders.
Methods: The acute pharmacological test of KMC recorded no death or any signs of effectivity even at the highest dose of 4000 mg/kg body weight. The effect of chronic administration of KMC on hematological parameters was determined by administrating chronically to the male Sprague-Dawley rats at a dose of 100 mg per kg body weight for 40 days.
Results: There was a (10.12 %) decrease in the number of white blood cell count of the male rats, which, although not statistically significant yet it was prominent (p=0.248). Similarly, a negligible (0.12 %) decrease in the red blood cell count was observed, which was not statistically significant at all (p=0.965). Conversely, the platelets count showed a (4.99 %) increase in the experimental animals, while this increase was not significant, yet it was prominent (p=0.296). Furthermore, a (1.89 %) decline was observed in the platelet volume distribution width of the experiment rats, which, although not significant, yet it was noticeable (p=0.076).
Conclusions: From this study, it is evident that there is no significant change in the hematological parameters in the body of the treated rats, therefore it is safe to use in usual dose. Further research and analysis with biochemical parameters should be done to reconfirm the safety of this ayurvedic medicine.

Published: February 2025

Background: Type 2 diabetes mellitus (T2DM) and hypertension (HTN) are common comorbid conditions that pose significant management challenges due to drug-related problems (DRPs), which can adversely affect clinical outcomes. This study aimed to evaluate the prevalence and types of DRPs in T2DM and HTN patients, analyse drug utilization patterns and identify factors influencing DRPs.
Methods: A prospective observational study was conducted over six months at a multi-specialty hospital in Bengaluru. Data from 110 adult patients with T2DM and HTN were collected, including demographics, clinical history and medication records. DRPs were identified using the Pharmaceutical Care Network Europe (PCNE) and Hepler-Strand classifications.
Results: The mean age of the participants was 63.45±13.66 years, with a nearly equal gender distribution. Monotherapy (37.27%) and dual therapy (33.63%) were the most common T2DM treatments, while calcium channel blockers (37.27%) and beta blockers (36.36%) were the predominant antihypertensives. DRPs were observed in 36.36% of patients, with untreated indications (14.54%) and drug-drug interactions (13.63%) being most common. Factors such as smoking and alcohol consumption were associated with higher DRP prevalence.
Conclusions: DRPs significantly impact the management of T2DM and HTN, highlighting the need for regular medication reviews and targeted interventions to optimize therapeutic outcomes in these patients.
