Antioxidant, anti-inflammatory and anti-glycation activities of some 4-aminoantypyrine derivatives: In vitro and in silico study
Authors: Erazua Ehimen Annastasiaa , Babatunde Benjamin Adeleke
Published: June 2024

Aminoantipyrine exhibits antioxidant and anti-inflammatory effects. However, its potential as an anti-glycating agent has not been extensively studied. This research aims to investigate the antioxidant, anti-inflammatory, and anti-glycation properties of specific derivatives of 4-amino antipyrine through experimental and theoretical methods. Thirteen Schiff bases were synthesized by reacting 4-aminoantipyrine with substituted benzaldehydes, and seven ether derivatives were obtained from these Schiff bases via Williamson ether synthesis. The compounds were characterized using FT-IR, UV-visible, EI-MS, and 1H NMR analyses. Cytotoxicity assessments were conducted using brine shrimp and 3T3 mouse fibroblast cell lines. Molecular descriptors were obtained from Density Functional Theory (DFT) calculations, and molecular docking was used to determine binding affinity. Additionally, in-silico ADMET (adsorption, distribution, metabolism, excretion, and toxicity) screening was performed. The synthesized compounds were evaluated for anti-inflammatory, antioxidant, and anti-glycation properties. The results showed promising activities for three compounds in the anti-inflammatory assay. Five compounds demonstrated significant antioxidant effects, while eight exhibited moderate anti-glycation properties. Compounds S1 and S13 show potential inhibition against the anti-inflammatory, antioxidant, and anti-glycation activities. DFT calculations and molecular docking identified S6, S7, and S9 as the most active compounds. All compounds displayed favorable results in terms of oral bioavailability, lipophilicity, pharmacokinetics, and toxicity prediction. These derivatives of 4-aminoantipyrine were non-toxic and showed potential as drug candidates due to their anti-inflammatory, antioxidant, and anti-glycation properties.

Background: Several orofacial tumours affect children, and these tumours pose a major health challenge due to the associated morbidity and mortality, mostly with malignant tumours.
Objective: To determine the clinico-pathologic pattern of childhood orofacial tumours seen in a tertiary health institution in South-south Nigeria.
Method: A cross-sectional retrospective study from the histopathology archives of the Department of Oral and Maxillofacial Pathology and Medicine, University of Benin Teaching Hospital (UBTH), Benin City, over 15 years (2008–2022). All the tumours of the orofacial region histopathologically diagnosed in patients 16 years and below were assessed and reviewed.
Results: A total of 105 cases were included. There were 61 males (58.1%) and 44 females (41.9), giving a male-to-female ratio of 1.4:1. The age range was 2 to 16 years with a mean age of 9.55+3.973 years. The peak age of the tumours was observed in the 13 to 16 years age groups (n=31, 29.5%). The mandible (n=43, 41.0%) was the site most commonly affected, followed by the maxilla (n=18, 17.1%). The lymphomas were the most common tumours observed (n=34, 32.4%), consisting mostly of Burkitt’s lymphoma (n=22, 21.1%). The lymphomas were mostly seen among the 5 to 8 years age group (n=19, 55.9%), with 73.5% of them occurring more in males (n=25) and affecting the mandible (n=13, 38.2%) mostly.
Conclusion: This study shows that orofacial tumours in children are diverse, and the most prevalent were Lymphomas, especially the Burkitt’s type. A good understanding of these tumours in children by clinicians would assist with the timely identification of cases and actions instituted to adequately manage them.

Authors: JAURO Tabitha Sahabo , SOFOLA Oyinkansola Olulola , UTI Omolara Gbonjubola
Published: June 2024

Background: Teething is a normal physiological process which involves the eruption of primary teeth into the oral cavity with minimal local symptoms, but no severe systemic involvement. However, Mothers worldwide associate different severe systemic symptoms with teething and indulge in different teething practices. This misconception leads to delays in prompt diagnosis and treatment of some childhood diseases. Moreover, some of these teething practices are harmful to the children.
Objective: To assess the knowledge, myths, and practices of teething among Nigerian mothers in Pakoto, a rural Local government area in Ogun State.
Methods: This was a cross-sectional study conducted at Pakoto Primary Health Care Centre, Ifo Local Government Area (LGA). Ogun State, Nigeria. Participants were mothers who attended the immunization clinic. Knowledge, myths, and practices for teething in the participants were assessed using a well-structured, pretested, open-ended, interviewer-administered questionnaire.
Results: One hundred mothers participated in this study. The mothers’ ages ranged from 19-51 years. The majority (65%) of the mothers had a fair knowledge of teething and the level of knowledge of teething increased with increasing level of education. 81% of the mothers attributed systemic symptoms with teething. Fever (58%) was the most associated symptom and medication (75%) was the most common teething remedy used by the mothers. These remedies were either self-prescribed or prescribed by nurses in the community.
Conclusion: Very few mothers have good knowledge of teething, most of the mothers have misconceptions about teething and various practices are being done as remedies for teething. Therefore, proper education is required among these mothers.

Coccidiosis is a neglected disease that affects small ruminants, including goats, in sub-Saharan Africa. This study aimed to assess the  prevalence, risk factors, and abomasal morpho-pathological changes associated with sub-clinical Eimeria gilruthi infection in adult goats  from three localities in Oyo and Ogun States, Nigeria. A total of 103 abomasal samples were collected from West African Dwarf (WAD)  goats in the aforementioned states. Data on husbandry system, housing, sex, age, and colour of the animals were recorded. Examination  for the presence of Eimeria schizonts, gross and histopathological analyses were conducted. The overall prevalence of E. gilruthi infection  in WAD goats was 67.0%. Ogun State exhibited a higher prevalence (87.5%) compared to Oyo State (12.5%). Among the three  localities, Ayetoro had the highest prevalence (88.2%), followed by Odeda (86.8%), while Beere had the lowest prevalence (16.1%). The  semiintensive grazing system and housing with wood and scrap materials were associated with higher infection prevalence. Age and skin  color did not significantly influence the infection rate. Gross and histopathological examinations unveiled thickening of the  abomasal wall with prominent nodules. Schizonts, surrounded by inflammatory cells and edema fluid, were observed within enterocytes.  Morphological and morphometric analysis of the schizonts revealed diverse developmental stages and characteristic features. In  conclusion, sub-clinical E. gilruthi infection is prevalent among adult goats in Oyo and Ogun States, Nigeria. This study provides vital  insights into the prevalence, risk factors, and morpho-pathological changes related to sub-clinical coccidiosis in goats, which can  contribute to improved management and control strategies for this disease.

This study was to gather first-hand information on the human capital input of the Nigerian cattle industry. A questionnaire was  administered to 26 cattle farms across Nigeria of which we received a response from each farm. Most of the farm surveyed were owned  solely by individuals 18(69.23%) and the male gender 24(92.31%). There were more farmers 25-50 years 22(84.62%) than those >50 years  4(15.38%). The majority of the farmers had tertiary education 18(69.24%), while 13(50.00%) and 11(42.31%) farmers had >10 years and 5 –  10 years of experience in cattle farming, respectively. Ten (38.46%) farmers each considered cattle farming out of interest and as their  profession. Poor funding 13 (50.00%) was the major challenge to cattle farming. The predominant cattle breeds were indigenous mix  18(75.00%) and improved crossbreed 7(20.78%). Semi-intensive 15(57.69%) was the most common management system, however, the  main farm sizes were small 13(50.00%) and medium-sized 12(46.15%), while boreholes 15(57.7%) and streams/well-water/rivers 11(42.3%)  were the major sources of water. Majority of the cattle farms sometimes 15(57.7%) experience food shortage but never  14(53.80%) water shortage. Nearby veterinary services were present in 22(84.62% farms but absent in 4(15.38%). The study shows that  funding is a challenge to cattle farming in Nigeria. This is evident in the small-sized farms, semi-intensive management practices and the  occasional shortage of food.

The present study was conducted to investigate the differences in susceptibility of the whiteleghorn breed of chicken to the haemo-pathological effects of avian coccidiosis when compared to commercial broilers. An experiment was performed with twenty-day-old  chicks (10 whiteleghorns and 10 broilers) which were grown for 3-weeks before infecting them. The chicks were first confirmed to be free  from intestinal parasites then 5 birds each, randomly selected from the two breeds, were orally inoculated with Eimeria oocyst.  Thrombocyte numbers and packed cell volumes (PCVs) were measured to indicate thrombocytopaenia and anaemia respectively. This was determined from blood obtained from the chicks on the 10th day post-inoculation. An estimate of the effect-size revealed that  coccidiosis produced a negligible effect (a 5% decrease) on the thrombocyte number of white-leghorns. However, no effect was observed  on the PCV of the same breed. On the contrary, a 47% decrease in the thrombocyte number and a 29% decrease in the PCV of broilers can  be attributed to coccidiosis. The extensive system of breeding white-leghorns satisfied the conditions necessary for natural selection  of favourable traits to occur in the breed. This might explain the difference in susceptibility to the haemo-pathological effects caused by Eimeria parasites because commercial broilers that are managed intensively, do not survive long enough, thereby disrupting natural  selection. The difference implies that an apparently healthy flock of white-leghorn may be a reservoir of the infection, which could be  transmitted to susceptible breeds.

Authors: Terfa AJ , Abenga JN , Rabo JS
Published: June 2024

This study was undertaken to determine the prevalence of Trichomonas gallinae and the pathologies associated with it in domestic pigeons in Makurdi, Benue State Nigeria. A total of 310 domestic pigeons comprising 171 (55.2%) males and 139 (44.8%) females were sampled. Of this number, 133 (42.9%) were sampled during the dry season and 177 (57.1%) were sampled during the wet season. Prevalence of infection, deviations in body weight, haematology, serum proteins as well as gross and histopathological changes were investigated. The prevalence was 67.7% (210 pigeons). Based on sex and season distribution, the prevalence of trichomoniasis was significantly higher in males (P < 0.05) (37.7%) than in females (30.0%) and not significantly higher during the wet season (35.5%) than in the dry season (32.3%) (P > 0.05). The mean (± SD) body weight was significantly (P < 0.05) lower in pigeons infected with Trichomonas gallinae (223.3 ± 47.96 g) than in non-infected pigeons (244.0 ± 46.21 g). The total protein and globulin levels of Trichomonas gallinae-infected pigeons were significantly (P < 0.05) lower than those of the non-infected group. The total leukocyte counts, heterophil, monocyte and eosinophil counts were also significantly (P < 0.05) higher in the Trichomonas gallinae infected group than non-infected pigeons. Grossly, the lesions observed included raised caseous materials in the crop, pale areas on the proventricular mucosa and congested liver. Microscopically, marked infiltration of mononuclear inflammatory cells in the mucosa of the crop and proventriculus, with multifocal degeneration and necrosis of the proventricular glands. In conclusion, Trichomoniasis is common in domestic pigeons in Makurdi, Benue State, Nigeria and the parasite is capable of causing marked pathology in tissues.

Purpose: To elucidate the anticancer mechanism and molecular targets of the aqueous fraction from Cotinus coggygria leaf extract in  A375 malignant melanoma cells.
Methods: Aqueous ethanol extract from the leaves of C. coggygria was fractionated into the aqueous and chloroform fractions by solvent–solvent partition. A375 cells were treated with the aqueous fraction at various concentrations and  incubated for 72 h. The effect of the aqueous fraction on programmed cell death by staining with Annexin V/Propidium iodide ias well as  on cell viability and adhesion through labeling with fluorescein diacetate were determined under fluorescence microscopy. In addition,  the clonogenicity assessment, comet assay evaluation of genotoxic properties, characterization of thermodynamic behavior of cells by  differential scanning calorimetry, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) on the expression of genes  involved in processes of apoptosis and cell cycle control were determined.
Results: The number of viable adherent cells was reduced by  38.00 and 85.06 % at 20 and 80 µg/mL, respectively compared to untreated cells. In addition, a significant, dose-dependent reduction in  the clonogenicity of melanoma cells was observed, culminating in an almost complete inhibition of cancer cells colony-forming ability at  40 and 60 µg/mL of the fraction. Treatment with the fraction increased comets of Classes 3 and 4 to 35 %, while comets of Class 5, which  corresponds to the highest level of DNA fragmentation, increased to 2.25 %. Also, the gene damage index (GDI) was highest (1.2) at the concentration of 40 μg/mL. Furthermore, the expression levels of BAX, CASP8 and CDKN1A were upregulated and MYC expression  decreased after treatment with the aqueous fraction.
Conclusion: Cotinus coggygria possesses significant in vitro anti-melanoma  potential. Future studies will be focused on the in vivo assessment of its therapeutic qualities in experimental animals.

Purpose: To investigate the potential antioxidant, anti-inflammatory and antiulcer effects of methanol extract of Ceratonia siliqua (Fabaceae).
Methods: The methanol extract of Ceratonia siliqua pulp was obtained using Soxhlet apparatus. Xylene (20 µL) induced ear  inflammation  administered intraperitoneally and HCl/ethanol solution (1 mL) induced gastric ulceration administered intra-gastrically   were used to induce inflammation and gastric ulcer, respectively. Twenty-four mice were randomly divided into 4 groups (n = 6).   Furthermore, eighteen rats (Sprague Dawley) were divided into 4 groups. Control group received (10 mL/kg of saline), Ceratonia siliqua   group received (250 and 500 mg/kg), and other groups received diclofenac sodium (10 mg/kg; p,o), and omeprazole (30 mg/kg; p,o).   Phytochemical screening was carried out by following standard procedures. The percentage of inhibition, pH, and ulceration index were   measured using pH metric titration and degree of ulceration. The antioxidant capacity was determined in vitro using radical DPPH   scavenging and FRAP assays.
Results: Phytochemical screening reveals the presence of flavonoids, tannins, quinones and sterols. Acute   toxicity assessment showed that methanolic extract of Ceratonia siliqua has a DL50 higher than 5 g/kg. Oral administration of methanolic   extract of Ceratonia siliqua (500 mg/kg) reduced significantly (p < 0.001) the percentage inflammation and ulceration index  in  both assays in comparison to control groups, these effects were comparable to those observed in reference drugs. The extract   possessed a strong antioxidant capacity with low IC50.
Conclusion: Ceratonia siliqua extract has antioxidant, anti-inflammatory and anti- ulcer properties. Standardization of Ceratonia siliqua extract will be required for the development of lead molecules against ulcers and   inflammation.
An analysis of minimal pairs in Igbo using a multimodal approach to speech perception
Authors: Onuoha Chinenye Esther , Uba Ebele Deborah
Published: June 2024

Speech perception is the process by which the sounds of a language are heard, interpreted and understood. The traditional assumption that language is an auditory phenomenon was over ruled by the McGurk effect which proved by the use of experiment that visual signal also assists the auditory signal in the perception of speech sounds of a language. This work aims at examining minimal pairs in Igbo to determine if this theory of multimodal (audio-visual) perception of speech is applicable. The minimal pairs used in this work are extracted ten Igbo native speakers comprising of six females and four males, and from existing Igbo literature on minimal pairs while some are by introspection of the researchers as native speakers of the language under study. The variety of Igbo used in this work is the standard Igbo which is the variety of the variety that is officially recognized. For data analysis, the Multimodal Theory of speech perception was applied. Findings indicate that the native speakers of Igbo do not use visual information in order to properly perceive the sounds of their language, even those that are minimal pairs. The work concludes that the need for visual information for adequate identification, perception and comprehension of speech sounds cannot be said to be a general phenomenon since native speakers of a language could without the visual information, perceive and identify their speech sounds when audio recorded not minding the confusion that usually arises with minimal pairs. This work suggests that the Multimodal Theory of speech perception may only be applied when working with non-native or non-fluent speakers of a language.

An Effective Hybrid Model for Predicting Air Quality of Ankara
Authors: Utku Anıl , Can Ümit
Published: June 2024

Increasing industrialization, population growth, urbanization and increase in fossil fuel consumption lead to air pollution that affects human health by polluting the atmosphere. Particulate matter, known as PM10 and PM2.5, are air pollutants that can remain suspended in the air in solid, liquid or both states. Substances are described according to their aerodynamic diameter, known as particle size. Estimating particulate matter concentrations is very important for human health and the environment. In this study, a hybrid deep learning model was developed for air quality prediction using PM2.5 and PM10 concentration data obtained from Bahçelievler, Demetevler, Sincan and Törekent air quality monitoring stations in Ankara. In the developed model, it was aimed to use the successful features of CNN and LSTM models. The developed CNN-LSTM model was compared with LR, RF, SVM, MLP, CNN and LSTM using MSE, RMSE, R2, and MAE. Experimental results showed that the CNN-LSTM model outperformed the compared models and each station had an R2 of approximately 0.9.

Authors: Şan Uğurcan , Aytekin Mehmet Ersin , Yüce Ali
Published: June 2024

Photovoltaic (PV) efficiency can be defined as the ability of solar cells to generate electricity at the highest rate from light energy. Today, there is a rapid transition from energy production based on fossil fuels, which have irreversible effects on the environment, to energy production with renewable energy sources. The discovery of photovoltaic systems in semiconductor technology and their use in energy production makes energy production with solar energy indispensable. However, the efficiency of PV panels is highly affected by environmental factors. In particular, overheating of the panels reduces the panel efficiency considerably due to the nature of the semiconductor material. On the other hand, another challenge in PV systems is to analyze the performance of the PV system under varying load conditions by considering many parameters such as sunlight intensity, direction/tilt, weather conditions, temperature, and panel at the same time. Therefore, in this study, an Internet of Things (IoT) based PV panel performance test system is designed to facilitate data collection for efficiency analysis of PV systems. Thanks to this system, remote monitoring of PV system performance is realized with IoT. The contribution of the cooling fans placed at specified locations on the panels to the efficiency of the PV panels was investigated. Overheating of PV panels is prevented by using cooling techniques. At the same time, performance data of both the system with and without cooling system were stored in the cloud environment. Thanks to the IoT application, the current, voltage and power values of the PV panel were monitored instantaneously. The data collected in the cloud in the uncooled and active cooling state of the PV panels were analyzed graphically. In the findings, it was observed that there was a 4.7% performance increase in PV panel efficiency using active cooling system.

Zinc deficiency poses a serious threat to numerous crops and global human population. Recently, soil biocharamendment has been promoted as a sustainable farming method. However, its consequence on the bioavailability of Znin cereal crop has not been fully addressed. In the present study, 0.01% Zn-SO4 (w/w) was loaded in fruit waste, farmyardmanure and coconut shell pyrolysis at 400℃, for 2 h to make fruit waste Zn-modified biochar (FWZn-MBC), farmyardmanure Zn-modified biochar (FYZn-MBC) and coconut shell Zn-modified biochar (CSZn-MBC). Except controltreatment, all the modified biochars were applied at 1, 2 and 4% doses on zinc availability, speciation, pearl millet growthand chemical properties in Zn-deficient soil. The obtained results show that Zn mobility in soil was 70.04% withapplication of FYZn-MBC 4% as compared to other treatments. The maximum uptake of Zn in shoot and root by pearlmillet plant was observed by 74.02 and 53% with addition of FYZn-MBC 4% as compared to control soil, due to increaseof soil organic matter. The chlorophyll SPAD values in the pearl millet aerial surface increased from 30.23 to 39.24%with application of FYZn-MBC 4% than control soil. The exchangeable fraction of Zn increased from 7.34 to 14.71%with application of FYZn-MBC 4%. The correlation matrix results indicated that CaCO3 positively correlated with soilpH, and soil organic matter had strong correlation with chlorophyll. Overall, future studies must be carried out to examinethe long-term impact of FYZn-MBC 4% on Zn phyto-availability in Zn-deficient soil

Published: June 2024

Os alunos do ensino secundário desenvolvem durante o seu percurso escolar secundário diversas capacidades de liderança. De facto, esta área de estudo investigacional tem atraído pouca atenção da parte de investigadores portugueses. A fundamentação conceptual para este estudo de investigação baseou-se no modelo da teoria das inteligências múltiplas desenvolvido por Howard Gardner. Os objectivos principais deste estudo foram o de a) analisar as características de liderança dos alunos do ensino secundário em duas escolas (uma urbana e outra rural) da Região Autónoma da Madeira (Portugal) e, b) determinar as diferenças existentes no que concerne ao tipo de escola e ao género dos estudantes em oito domínios distintos: 1) auto-gestão; 2) relações interpessoais; 3) resolução de problemas/tomada de decisão; 4) desenvolvimento cognitivo/análise crítica; 5) organização e planeamento; 6) auto confiança; 7) sensibilidade para a diversidade; e, 8) tecnologia. Foi usado, na recolha de dados, o Student Leadership Outcomes Inventory (SLOI) (Vann, 2004), um instrumento com 60 itens que foi construído para medir os resultados das experiências de liderança dos alunos em oito áreas distintas. Foram encontradas diversas diferenças embora não significativas. Em consequência e, no general, podemos afirmar que os alunos Madeirenses terminam a ensino secundário e chegam à Universidade ou ao mercado de trabalho com diversas características e capacidades de liderança bem desenvolvidas.

Published: June 2024

Perkembangan dan inovasi teknologi berpengaruh secara besar terhadap kehidupan masyarakat saat ini, termasuk dalam ranah industri kreatif. Dampak ini terlihat dengan adanya teknologi blockchain dan Non-Fungible Token (NFT) sebagai sarana untuk mendesentralisasi industri tersebut. Perkembangan ini juga menimbulkan risiko tersendiri, dimana karya cipta dapat disalahgunakan oleh pihak-pihak yang tidak berwenang melalui penciptaan dan transaksi NFT dalam sistem blockchain, sehingga mengakibatkan timbulnya kerugian bagi pencipta, baik secara materiil, maupun secara imateriil. Risiko inilah yang menjadi alasan diperlukannya pengkajian terhadap perlindungan hukum bagi hak pencipta dalam proses penciptaan dan transaksi NFT, baik berdasarkan Undang-Undang Nomor 28 Tahun 2014 tentang Hak Cipta, maupun ketentuan-ketentuan lain yang berlaku dalam proses tersebut agar dapat diketahui secara jelas perlindungan-perlindungan hukum yang diberikan kepada pencipta dalam pelaksanaan proses tersebut, serta dapat memajukan industri kreatif di Indonesia.

الإستشهاد بشعر امرئ القيس في اصول الفقه
Authors: Özdemir Muhittin
Published: June 2024

استشهد عدد كبير من علماء أصول الفقه بكلام امرئ القيس في مختلف مباحث هذا العلم، وأكثر مبحث استُشهد بشعره فيه هو مبحث الألفاظ، بينما كان مبحثا الأدلّة والأحكام الأقلّ استشهادًا بشعره، وأمّا مبحث الاجتهاد فلا يكاد يوجد ممّا يُستشهد بشعره، وهذا يدلّ على أنّ أهمّيّة شعره مقصورة على الألفاظ والبلاغة وما أشبه ذلك من العلوم اللغويّة.
فالعالم الظاهريّ ابن حزم الأندلسيّ (ت .456/1064) بعد ما عرّف الشريعة في اللغة بأنّها «الموضع الذي يتمكّن فيه ورود الماء للراكب والشارب من النهر»، استشهد لمعناها اللغويّ بشعر امرئ القيس.
وكذلك العالم الحنفيّ أبو بكر شمس الأئمّة محمّد بن ابي سهل السرخسيّ (ت. 483/1090) مثّل في مسألتي إعجاز القرآن والتواتر بشعر امرئ القيس، وقيّد العالم الحنفيّ الآخر الشهير بمُلّا الفناري (ت. 834/1531) نفس الشيء.
وذكر العلاّمة سعد الدين مسعود بن عمر التفتازاني (ت. 279/1390) حين تناول مسألة حدّ القرآن شعر امرئ القيس دليلًا له.
واستشهد تاج الدين السبكيّ (ت. 771/1370) عند ذكر قول (لا تثنّى فلتاته) في بيان صفة محاسن رسول للّه صلّى اللّه عليه وسلّم ببيت امرئ القيس.
ويُمثّل باسم امرئ القيس في بعض مؤلّفات أصول الفقه في مبحث القياس عند بيان معناه اللّغويّ فيُقال: "ومن معناه الاعتبارُ، يُقال: قِسْتُ الشّيءَ، إذا اعتبرته قيسًا وقياسًا، ومنه قيس الرأي، وامرؤ القيس لاعتبار الأمور برأيه".
ومن المباحث التي يُستشهد فيها بشعر امرئ القيس مبحث الأحكام الشرعيّة، إلّا أنّ الاستشهادات قليلة في مبحث الأدلّة الشرعيّة، وكذلك الأحكام الشرعيّة، وهذا يدلّ على أنّ الاستشهاد بكلامه مهمّ في العلوم الإسلاميّة عامّة وعلم أصول الفقه خاصّة من حيث الألفاظ، وأمّا بالنسبة إلى المباحث الأخرى فلم يُستشهد بكلامه ألبتّة.
الاستشهاد بشعر امرئ القيس يكاد ينعدم في مبحث الاجتهاد، وهذا يدلّ على أنّ الاستشهاد بشعره يقتصر على اللّغة في علم أصول الفقه.
ومن الألفاظ التي استشهد بشعره فيها: النصّ، المجمل، المفسّر، البيان، المشترك، المترادف، الحقيقة والمجاز، المؤوّل، العموم والخصوص، بالإضافة إلى معاني بعض الكلمات ومعنى الأمر، كما استشهد بشعره فيما لا يدخل تحت عنوان معيّن.
ومن أكثر الموضوعات التي يُستشهد بشعره في مؤلّفات أصول الفقه من بين الألفاظ هي معاني الأمر، وقد استشهد الأصوليّون في مؤلّفاتهم لذلك المعنى بشعر امرئ القيس على اختلاف مناهجهم وحجم آثارهم.
وبالجملة فإنّ شعر امرئ القيس يُعدّ بلا شكّ ركيزة من الركائز الشعريّة المهمّة التّي اعتمد عليها الأصوليّون في استشهاداتهم اللغويّة لاسيّما وهو
SISTEMA DE INFORMAÇÕES DE CUSTOS DO GOVERNO FEDERAL (SIC) NA REDE FEDERAL DE EDUCAÇÃO PROFISSIONAL, CIENTÍFICA E TECONLÓGICA: UMA ANÁLISE DA ACEITAÇÃO E USO DO SISTEMA
Authors: Galindo Valentim Wagner Felipe , Ceolin Alessandra Carla
Published: June 2024

O estudo objetivou analisar quais os fatores que influenciam a aceitação e uso do SIC pelos profissionais de contabilidade, responsáveis pelas setoriais contábeis de órgão das instituições que compõem a Rede Federal, com fundamento na Teoria Unificada de Aceitação e Uso de Tecnologia (UTAUT). Trata-se de pesquisa descritiva, quantitativa na apresentação dos dados e qualitativa na análise dos resultados, com procedimento de coleta survey, aplicado por meio de três questionários estruturados. Foram obtidas 4 respostas das 7 instituições usuárias do SIC e 14 respostas das 35 organizações não usuárias do sistema. Nos resultados os usuários do SIC se mostraram indiferentes em relação aos fatores determinantes da UTAUT. Já, os não usuários, em sua maioria, acreditam que o uso do SIC irá ajudar a alcançar ganhos de desempenho, a maior parte é indiferente em relação à expectativa de esforço, tem baixa percepção acerca da influência social e, para as condições facilitadoras, há variações entre os determinantes do construto. Também foi possível identificar que há poucas instituições da Rede Federal utilizando o SIC. A pesquisa contribui com o conhecimento para a apuração de custos no setor público, que está em formação, e necessita ser consolidada. Também buscou estimular a mudança de comportamento dos gestores públicos, de modo que enviem esforços para a implantação do SIC e uso da informação na tomada de decisões.
FATORES CRÍTICOS DE SUCESSO NA IMPLEMENTAÇÃO DO SISTEMA DE CUSTOS NO SETOR PÚBLICO FEDERAL

A necessidade de utilização de um sistema de custos pelas entidades do setor público no Brasil tem suas raízes históricas relacionadas às recentes crises fiscais e às reformas administrativas. Nesse cenário, esta pesquisa tem como objetivo analisar a influência dos fatores críticos de sucesso na implementação do sistema de custos no setor público, adotando-se como lócus de pesquisa a Administração Pública Federal (APF). Para tratar a questão da pesquisa, foram levantadas evidências empíricas tendo como suporte a teoria da regulação contábil, utilizando-se como ferramentas metodológicas entrevista, questionário e regressão logística multivariada. Inicialmente, a pesquisa contou com depoimentos de especialistas, visando levantar informações de forma exploratória; em seguida, por meio da regressão logística, verificou-se se havia associação entre os fatores críticos analisados e o sucesso da implementação do sistema de custos. Os resultados sugerem que no âmbito da APF os fatores políticos e técnicos e o tamanho da entidade pública tem afetado o sucesso da implementação do sistema de custos, indicando que os stakeholders possuem papel relevante em sua estruturação. Por outro lado, os fatores culturais não se mostraram estatisticamente significativos, revelando a necessidade de que outros estudos sejam feitos para compreender melhor as peculiaridades do ambiente do setor público.
