A Modified Rectal Mucosal Biopsy for the Diagnosis of Hirschsprung’s Disease
Authors: Sholadoye Tunde Talib , Aliyu Halima Oziohu , Mshelbwala Philip Mari
Published: September 2023

Background:

Full-thickness rectal biopsy is often used for the diagnosis of Hirschsprung’s disease (where a suction biopsy kit is not available). This is associated with some challenges such as limited theatre space and the need for general anaesthesia. We aim to highlight the usefulness and sensitivity of a modification of the rectal mucosal biopsy without general anaesthesia in the diagnosis of Hirschsprung’s disease.

Materials and Methods:

This is a retrospective analysis of children with Hirschsprung’s disease who had rectal mucosal biopsy over a 16-year period (January 2004–December 2019). Research was approved with institutional number ABUTHZ/HREC/H22/2022. The patients had the biopsy with small, curved artery forceps, surgical blade, and dissecting scissors. Histological analyses of tissue were done. Clinical data and results were recorded on a structured pro forma, and the data were analysed.

Results:

There were 263 boys and 97 girls with a median age of 10.5 months. Only 37 (10.3%) of the rectal biopsies were done by consultants. Hirschsprung’s disease was confirmed in 279 (75.5%) of the partial-thickness biopsies, whereas 52 (14.4%) biopsies were inadequate specimens. Resident doctors were responsible for 92.2% (47) of inadequate biopsies (P = 0.63), although they did 89.7% of all biopsies. In one (0.3%) patient, the procedure ended as a full-thickness biopsy leading to a significant haemorrhage that required blood transfusion.

Conclusions:

The modified rectal mucosal biopsy is a simple, safe, and effective method for making the diagnosis of Hirschsprung’s disease. This is performed without general anaesthesia and is useful where a suction biopsy kit is unavailable.

Authors: Alsawaf Mohamed Helmi , Shoushan Mohamed M. , Saad Khaled Abd-El Hamid , Nowair Ibrahim M.
Published: September 2023

Purpose

To evaluate the effect of piezo debridement with application of platelet-rich fibrin (PRF) on bone and soft tissue healing in patient with medication-related osteonecrosis of the jaw (MRONJ), both clinically and radiographically.

Patients and methods

At the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Tanta University, a prospective noncontrolled clinical study was carried out on eight patients above 30 years old who are proved to have MRONJ clinically and radiographically. Preoperatively, (ampicillin/sulbactam) with a dosage of 1.5 gm vial IV or IM and (doxycycline) 100 mg/capsule once daily were prescribed for all patients one week before surgery. Intraoperative, after surgical exposure of the affected bone, Surgery divided into resecting all the infected and necrotic bone with the piezoelectric vibrating tips connected to the piezoelectric bone surgery device until bleeding spots appear. Autologous PRF was applied, followed by double layer closure of the flap. All patients had postoperative, clinical evaluation of pain, wound healing and recurrence. Lab investigation, including CBC, ESR, C reactive protein was carried out for all patients. Radiographic evaluation was done using Cone Beam Computed Tomography (CBCT) after one-week and after 3 months postoperatively.

Results

In the first 2 weeks, most patients had complete relief of pain and swelling. Complete healing of the soft tissue was observed in five patients showing normal range of ESR and CRP, and three patients showed partial soft tissue healing and signs of recurrence clinically and radiographically. These findings shown that using piezo debridement combined with PRF has a positive effect on bone and soft tissue healing in patient with MRONJ.

Conclusion

Piezoelectric bone surgery in combination with PRF is an alternative treatment method in treatment of MRONJ as it provides minimally invasive surgical technique, effective in complete debridement of affected bone tissue and soft tissue.

Authors: ElHamid Ahmed R. A. , Masoud Gaber I. , Younes Abeer A.
Published: September 2023

Background

The aim of the study was evaluating of fracture resistance, marginal and internal adaptation of endocrowns using two different heat-press ceramic materials using the universal testing machine for fracture assessment and a scanning electron microscope (SEM) for marginal and internal adaptation assessment.

Methods

40 extracted human mandibular first molars were collected for the study. The teeth were mounted in acrylic blocks using a dental surveyor. All teeth were endodontically treated and prepared for endocrown restorations. All samples were divided into two groups according to the material used (n = 20): group (a) for lithium disilicate glass-ceramic (IPS e.max press) and group (b) for zirconia-reinforced lithium silicate glass ceramic (VITA Ambria). Specimens of each group were subdivided into two subgroups (n = 10): subgroup (1) for assessment of fracture resistance and subgroup (2) for assessment of marginal and internal adaptation. Waxing up all teeth was done using CAD/CAM technology. Endocrowns were fabricated with the heat press method. Bonded endocrown specimens were stored at 37°C and 100% humidity for 24 h in an incubator before testing. The fracture resistance of samples was tested using a universal testing machine. Marginal adaptation and internal adaptation were assessed using a SEM. Quantities variables were expressed as mean and standard deviation using one-way analysis of variance (ANOVA) followed by Tukey’s post
hoc test at (a = 0.05).

Results

The Vita Ambria mean values (2174.99 N±537.65) had more compressive strength than IPS e.max press mean values (1974.33 N±566.35). Considering the marginal adaptation test using SEM, there was no significant difference between both materials (P = 0.656) and there was also no significant difference between either of the materials (P = 0.855) after the internal adaptation test using SEM.

Conclusion

Vita Ambria endocrowns had higher compressive strength than IPS e.max press ceramic endocrowns. During the evaluation of marginal and internal adaptation, there was no significant difference between both materials and their values were within the clinically acceptable values.

Authors: Alsharqawy Maha A. , Etman Wedad M , Salama Mirvat M , Saleh Reda G.
Published: September 2023

Aim

To evaluate and compare initial enamel caries treated by ozone gel with or without nanohydroxyapatite paste or fluoride gel.

Materials and methods

30 intact, noncarious freshly extracted human premolars, were collected, cleaned from all soft debris and/or calculus and polished using prophy polishing paste. Each tooth was sectioned first at cement enamel junction (CEJ) to separate crown after removal of root. Each crown was mesiodistally sectioned to a thickness of 1–2 mm then stored in artificial saliva which was periodically changed. All the specimens were exposed to demineralizing solution at occlusal surface only (the surface of the study) for creation of enamel lesions. All the specimens were examined with, EDX and tested under PLM to evaluate enamel surface. After demineralization the specimens were divided randomly into three equal groups I, II and III consist of 10 specimens of each group. For group I Ozonized olive oil gel was used alone on occlusal surface for 1 min once daily, group II was treated as group I followed by application of 5% nanohydroxyapatite paste, while all specimens in group III were treated as group I followed by fluoride gel application. All the procedures at the three groups were repeated daily for 21 days.

Result

It was found that nonsignificant difference among the mean wt % values of mineral contents (Ca, P, and Ca/P ratio) between the three treatment groups at baseline and after demineralization (P ≥ 0.5), by using ANOVA test at remineralization stage it was found that (group II) recorded the highest mineral content with a mean value of 69.58 ± 1.54 followed by (group III) with a mean value of 69.36 ± 1.04 while the lowest mineral content mean value was 67.43 ± 0.92 which related to (group I). Also, highly statistically significant difference between the three groups was recorded (P = 0.001). Findings using PLM supported the previous results revealing decrease in optical reflectivity and the positive birefringent area which was about to appear broad positively birefringent body after demineralization and disappear after remineralization indicating a great mineral content recovery at all the three groups.

Published: September 2023

Aim

To assess the accuracy of using computer designed genioplasty osteotomy guide and customized repositioning plates in patients with chin deformities.

Methods

This was prospective randomized noncontrolled clinical study that was carried out on eight adult patients suffering from chin deformities as a result of unilateral temporomandibular joint ankylosis. Patients were selected from the outpatient clinic, Department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University. All cases were operated for genioplasty under general anesthesia. The incision was performed on the alveolar mucosa apical to the attached gingiva by 0.5 cm in two planes (mucosal and muscular), The cutting guide was seated to the mandibular dentition, the eight screw holes were then drilled, the cutting guide was temporarily fixed on the mandible by mini screws, once the osteotomy plane was marked by a surgical saw, the cutting guide was removed, osteotomy completed routinely and the customized reposition plates were installed to reposition the chin segment as planned. Finally, after the screws were placed and tightened, the chin segment was automatically moved to its final planned position and secured. Closure was done in two layers (the muscle layer followed by the mucosa).

Results

Genioplasty procedure using customized surgical guide and repositioning plates was performed in every case. Postoperative recovery was satisfactory for all patients. There were no intraoperative or postoperative complications, except self-limiting edema and some small hematomas with no clinical significance. Postoperative pain intensity measured by the Visual Analog Scale was acceptable for all patients. All cases reported full recovery from neurosensory disturbance after three months follow-up periods. Regarding patients’ satisfaction, all the cases were very satisfied (grade I) with a percentage of 100% on the third month postoperatively.

Conclusion

The results obtained from this study show that using customized surgical guide and repositioning plates in performing genioplasty had advantages over conventional technique as they provided greater accuracy, safety, less complication during the surgery with decrease in surgery time, and made the results of genioplasty procedure more predictable. So, using customized surgical guide and repositioning plates simplified the genioplasty procedure.

Patients and methods

Thirty-two patients were randomly divided into two groups of 19 each (group I: glue gun tray, group II: vacuum tray). The brackets were placed in their predetermined positions by reference, the working model with attached brackets was scanned with intraoral scanner images (image 1). After bonding, scanning for the patient teeth with bonded brackets was performed (image 2). Image 1 and image 2 were superimposed to compare the transfer accuracy of both methods. A 5% significance level and χ
2 test were used.

Results

No statistically significant difference was found between the two groups in the transverse and horizontal planes. In the vertical plane, group I was statistically significant higher (P ≤ 0.05) than group II.

Conclusion

The indirect bonding transfer process with glue gun trays resulted in bracket placement with high positional accuracy and a mild distal and gingival bias for all teeth groups.
Applications of Neural Networks to Metallic Flexor Geometry
Optimization of Flat Wipers
Authors: Chu Yi-Tzu , Huang Ting-Chuan , Liao Kuo-Chi
Published: September 2023

In recent years, demands of flat wipers have rapidly increased in the vehicle
industry due to their simpler structure compared to the conventional wipers.
Procedures for evaluating the appropriate metallic flexor geometry, which is one
of the major components of the flat wiper, were proposed in the authors’
previous study. However, the computational cost of the aforementioned procedures
seems to be unaffordable to the industry. The discrete Winkler model regarding
the flexor as the Euler–Bernoulli beam is established as the mathematical model
in this study to simulate a flexor compressed against a surface at various
wiping angles. The deflection of the beam is solved using a finite difference
method, and the calculated contact pressure distributions agree fairly with
those based on the corresponding finite element model. Flexor designs are paired
with various windshield surfaces to accumulate a sufficiently large simulation
database based on the mathematical model. An artificial neural network (ANN)
approach is developed to predict contact pressure distributions of the flexor
much faster than the mathematical model. Geometry of the curved surface is
represented by a shape code obtained via a principal component analysis (PCA)
and used in the ANN model. The ANN algorithm is also applied to efficiently
evaluate the wiping patterns according to the simulated contact pressure
distributions. These patterns are then classified by using a convolutional
neural network (CNN) to identify several suitable flexor designs for the
specific windshield. The flat wiper suggested by the current procedures is
experimentally validated to justify its qualified wiping performances.

Published: September 2023

Low-dimensional materials are essential in optoelectronic, electrical, and contemporary photonics areas because of their specific properties with decreased dimensions. Low-dimensional materials are those with dimensions in the nanoscale range that are between 1 and 100 nm. Halide perovskites of low dimension can be produced inexpensively using solution-processable procedures, unlike usual semiconductor nanomaterials. Since halide perovskite in thin layers may be produced utilizing a variety of solution-based techniques like simple spin coating. It is possible to produce it with a variety of compositions using low-cost, simple, and large-scale procedures. Quantum dots, perovskite nanoplatelets, nanosheets, perovskite nanorods or nanowires, and other low-dimensional perovskites are all examples of such small-dimensional devices that have been created in a range of morphologies (two-dimensional). In this work, a 1D array of perovskite solar cells (methyl ammonium lead halide) is modeled, and a performance study is done using the Finite Element method. It is observed that the proposed 1D array of methyl ammonium lead halide perovskite solar cells gains in recombination rate from 10-2 to 108, compared to 10-11 to 10-6 for the Si array. In addition, other core parameters, like the open circuit voltage Voc, the short-circuit current density Jsc, and peak power Pmax, are included. In this paper, 1-D nano technology is proposed for electric vehicles as coating material on the roofs or doors. Because of their surface to volume ratio, the throughput will serve the vehicle for its purpose.

Published: September 2023

Air pollution is one of the biggest issues facing the planet today. One of the major sources of environmental pollution is car emissions. Reduced use of fossil fuel signals the need to switch to other fuels. Every nation in the world is making numerous efforts to reduce the pollution that vehicles are responsible for. Utilizing alternative fuels effectively can reduce air pollution. Decreased fuel consumption results from increased use of biodiesel. For this study, biodiesel made from karanja oil was combined with additives like methanol, diethyl ether, and ethyl hexyl nitrate (EHN). B10, B15, and B20 blends are created in various compositions. For comparison, several fuel attributes for the aforementioned mixes and diesel were discovered. Biodiesel’s viscosity has been significantly lowered to improve mixture preparation and has a higher calorific value than base fuel. The testing for the aforementioned mixes was carried out on a VCR-style CI engine. Analysis was done on the performance parameters heat release rate, brake thermal efficiency, brake power, and indicated power. B10 has a little greater brake thermal efficiency than diesel fuel (32.57% vs. 31.63%, respectively). The effects of different pollutants, such as HC, CO, CO2, and NOx emissions, were compared to diesel fuel emissions. Compared to pure diesel, there is a reduction in HC, CO, and smoke emissions. However, NOx is more abundant than pure diesel.
Investigation of HVAC Kinematics Mechanism & Door Noise through Acoustical Duct Method
Authors: Sen Somnath , Goel Arunkumar
Published: September 2023

As HVAC noise is becoming one of the key factors to end users in terms of enhanced comfort, it is important to understand and evaluate various noise sources of HVAC in details. With detailed understanding of various sources, it becomes easier to take appropriate countermeasures in design and subsequently eliminate. There are many methods available in industry to investigate the noise sources in details however those options are expensive and time consuming and require deep understanding of the acoustic. Acoustical duct methods are one such method which proves to be very much helpful in identifying the noise sources from different aggregates like kinematics mechanism, door/damper, servomotors, heat exchangers etc. These sources are typically defined minor noise sources.

The present paper describes the detailed investigation of those minor noise sources through the use of acoustical duct method. An existing HVAC from passenger car was considered for this study. In order to take the noise measurement, acoustical duct was prepared as per standard. The HVAC was kept in a semi-anechoic test chamber and desired DC supply was provided to the HVAC. Noise sources from kinematics mechanism, servomotor, door/dampers were marked and measurement was done for those areas. Comparative matrix was prepared out of all the sources and evaluation was done to assess the noise level. This technique is already applied to major noise source identification and comparison like fresh air/recirculation air opening, face, defrost and blower motor. The study showed a remarkable difference between the minor noise sources leading to prominent sources. The method is quite helpful in order to prioritize the noise sources and take appropriate countermeasure to reduce the noise.
Postergamento e transvasamento nas traduções italianas de a relíquia de eça de queirós: em causa uma estética da ironia.
Authors: Pinheiro Duarte
Published: September 2023

Os neologismos da linguagem queirosiana são o ponto de partida para uma análise cuidada das traduções italianas de A Relíquia. Paolo Silenziario e Amina di Munno são os autores dessas traduções, que, apesar de divergirem entre si no tempo, são surpreendentemente convergentes sob o ponto de vista ideológico-morfológico. Veremos, entre outros aspetos linguísticos, como a igual opção dos tradutores em não traduzir os neologismos da prosa de Eça pode colocar em causa o total entendimento da obra, sobretudo no que toca às personagens Topsius e Filomena Raposo, e tornar diluída toda uma estética da ironia, imagem de marca do grande mestre do Realismo português.
Discursos de referência: representação e leitura do mundo através do teatro de wole soyinka
Authors: Figueiredo Rosa
Published: September 2023

Wole Soyinka é uma figura proeminente na literatura mundial contemporânea. Partindo da perspetiva da política de escrita pós-colonial de expressão inglesa, o desafio da complexidade da vida e obra do dramaturgo reside no facto de as meta-narrativas, que de forma imaginativa e discursiva estiveram na base dos grandes movimentos de libertação do século XX, não se apresentarem na escrita Soyinkiana de forma convencional. Acima de todas as lutas desencadeadas por estes movimentos está a luta pela auto-determinação, raíz existencial e expressiva da liberdade humana. Os melhores exemplos desta demanda no teatro Soyinkiano encontram-se em peças como A Dance of the Forests, Kongi’s Harvest, Madmen and Specialists and From Zia With Love. Os ensaios críticos de Soyinka operam, de igual forma, em variadíssimos contextos sociais e intelectuais cobrindo um extraordinário leque de tópicos, que vão desde a crítica literária à teoria estética, do teatro à história cultural, do poder político à ideologia, e mais recentemente, do extremismo religioso à poluição nuclear. Um tipo de atenção que tem sido decisivo na receção da obra de Wole Soyinka é a dos críticos literários profissionais, particularmente no que diz respeito a institucionalização do estudo académico da escrita anglófona do mundo em desenvolvimento na segunda metade do século XX.

Authors: Cunha Daisy , Nunes Ana , Pais Diana , Fernandes António , Lebres Vera
Published: September 2023

Este estudo teve por objetivo avaliar o Estado Nutricional de pacientes internados em Unidades de Longa Duração e Manutenção (ULDM). Para o efeito, foi realizado um estudo observacional, analítico e transversal que envolveu 14 ULDM da Região Norte de Portugal, no qual participaram 265 indivíduos – 147 do género feminino (55,5%) e 118 (44,5%) do género masculino. A média de idades foi 75,5 anos. Foram aplicados dois questionários: o Mini Nutritional Assessment (MNA), da Nestlé Nutrition Institute, para determinar o estado nutricional dos indivíduos; e um segundo questionário, elaborado pelos autores, para avaliar parâmetros relativos à alimentação fornecida ao utente, assim como o tempo de internamento. Os resultados revelaram que 59% dos indivíduos estavam desnutridos, 34,9% estavam em risco de desnutrição e 6,1% apresentavam um estado nutricional normal. Constatou-se ainda que o género, as patologias, a textura da dieta e a suplementação nutricional têm uma influência estatisticamente significativa no Estado Nutricional, uma vez que p-value < 0,05. Por sua vez, a idade e a composição nutricional não influenciam o Estado Nutricional, pois p-value > 0,05. Conclui-se, por isso, que a maioria dos indivíduos internados nas ULDM estavam desnutridos.

Published: September 2023

As Instituições Particulares de Solidariedade Social (IPSS) representam, no panorama nacional, um pilar de sustentabilidade, ao criar instituições com serviços qualificados, de modo a assegurar a prestação de serviços que, de outra forma, o Estado não conseguiria garantir por si só. Também a nível do Distrito da Guarda esta realidade se verifica. A falta de informação sobre os aspetos relacionados com a caracterização da motivação e liderança dos Presidentes das IPSS assume-se como determinante para um entendimento da realidade social do Distrito da Guarda. O objetivo deste estudo é disponibilizarmos essa informação considerada relevante e útil para que a Ação Social, ancorada nos apoios das Câmaras Municipais, Juntas de Freguesia, Instituto de Emprego e Formação Profissional e Centro Distrital, possa, de uma forma mais fidedigna, definir as suas políticas nesta área. O nosso ensejo é que este objetivo seja conseguido e doravante as respostas sociais, dadas às populações mais carenciadas e debilitadas, possam ter uma maior eficácia, fruto de uma melhor sustentação no conhecimento das IPSS do Distrito da Guarda e no perfil dos seus Presidentes.

Procura dos estudantes do ensino superior em turismo: realidade da ESTH/IPG
Authors: Salgado Manuel , Martins José , Godinho Adélia
Published: September 2023

A importância da área científica do Turismo no Ensino Superior (ES) em Portugal requer uma análise e interpretação do seu contexto educativo e formativo. Constata-se que as instituições académicas portuguesas investem significativamente nesta área de estudos desde o ano letivo de 1986/87. Além disso, o Processo de Bolonha conduziu a relevantes mudanças na filosofia e estrutura dos cursos superiores, nomeadamente a nível curricular e do processo de ensino-aprendizagem. Neste trabalho caracteriza-se a instituição e o projeto educativo da Escola Superior de Turismo e Hotelaria (ESTH) do Instituto Politécnico da Guarda e analisa-se informação secundária sobre os principais indicadores da oferta e da procura formativas dos seus cursos. A finalidade desta reflexão visa, sobretudo, interpretar e demonstrar a necessidade e o interesse do estudo da procura dos estudantes desta área de estudos a nível nacional, com particular atenção à realidade da ESTH, para compreender a evolução e as tendências do ES em Turismo. Alguns resultados permitem percecionar uma certa insustentabilidade da rede atual do ES que, naturalmente, se projeta na área científica do Turismo devido, em parte, ao crescimento excessivo do número de cursos a nível nacional que, na nossa perspetiva, condiciona o projeto educativo da ESTH.

Do estudo de validade, podemos concluir que os coeficientes de correlação item/total da escala apresentam valores significativos de serem considerados, destacando-se a consistência interna, medida através do alpha de Cronbach, onde se obteve o valor de (0.92), permitindo valores ajustados à sua utilização para se obter a informação que se pretende junto desta população.
A atividade física como indicador de risco da periodontite. Revisão narrativa
Authors: Serra Nuno , Vila-Chã Carolina , Domingues Elsa
Published: September 2023

A periodontite é uma patologia multifactorial de etiologia bacteriana, caracterizada por uma inflamação crónica que afecta os tecidos de suporte dos dentes. Na literatura tem sido apontada uma possível associação entre a atividade física e/ou aptidão física do indivíduo e a doença periodontal. O objectivo deste artigo foi realizar uma revisão da literatura sobre a relação entre a prática de atividade física e a doença periodontal. Foi efetuada uma pesquisa na base de dados Pubmed, relativa a estudos humanos que avaliassem a influência da atividade física na periodontite. Foram mencionadas quatro teorias que poderiam ligar estes dois conceitos: teoria inflamatória, metabólica, psicossocial e do fluxo sanguíneo. Foram selecionados quatro estudos que relacionaram a aptidão física com a periodontite. Três aludiram a uma relação entre melhores níveis de aptidão cardiorrespiratória e uma melhor saúde periodontal. Noutro sentido, um estudo não relacionou a aptidão física com a periodontite. Identificámos também três estudos que associaram baixos níveis de atividade física a uma frequência aumentada de periodontite. Devido à existência limitada de estudos longitudinais, é difícil considerar a baixa aptidão física e/ou atividade física como um factor de risco para a doença periodontal.

In this study, the spatiotemporal dynamics of the urban environment and thermal environment of Benin City are analysed. The maximum likelihood algorithm for land use and land cover (LULC) analysis was used to categorise Landsat images. The relative transfer equation (RTE) and land surface emissivity (LSE) approaches were used to retrieve the land surface temperature (LST), whereas the Cellular Automata-Markov (CA-Markov) algorithm was used to forecast the LULC for 2030. The findings reveal evolving LULC patterns over time. Built-up areas made up 19.66% of the total area in 1990, bare ground made up 9.25%, and vegetation made up 71.08%. Built-up areas reached 23.40% in 2000, bare land reached 12%, and the vegetation cover dropped to 64.16%. In 2010, there was an increase in the proportion of built-up areas to 44.38%, the proportion of bare land increased to 22.20%, and the proportion of vegetation decreased to 33.42%. Built-up areas reached 61.79% in 2020, compared to 22.29% for bare land and 61.79% for vegetation. Regarding the relationship between the fractional vegetation cover (FVC) and LST, for the years 1992, 2002, 2012, and 2022, R2 is equal to 0.87097, 0.84598, 0.83957, and 0.71838, respectively. Conversely, for the LST and the normalised difference built-up index (NDBI), the R2 values were 0.5975, 0.73876, 0.86615, and 0.90368 for 1992, 2002, 2012, and 2022 respectively. In conclusion, this study evaluates Benin City's metropolitan setting and thermal environment. According to the LULC study, there are more built-up areas and less vegetation. The impact of the changing land cover on urban thermal features is shown through correlation analysis, which links more built-up regions to higher LSTs. These results can support urban design efforts to lessen the effects of climate change. Examining the distribution of the LST and its associations with particular land cover types was the major goal of this study. Future research will undoubtedly use this study as a useful reference when modelling urban terrain and temperature variations.

Background: Adverse effects of weak governance on health, is a serious policy subject matter for policymakers, health experts, and researchers. Therefore, this study examines the effect of governance and health expenditure on under-five and adult mortality in emerging economies between 2000 and 2016. 
Methods: Employing data from World Bank World Development Indicators, the study applied panel procedures namely cross-sectional dependence test, Westerlund cointegration, and cross-section augmented Dickey-Fuller (CADF) panel unit root test that can deal with the effects of cross-sections in the series. The study examined the long-run relationship between governance and health outcomes by using the panel fully modified least squares (FMOLS) and the fixed effects model for a robust check.
Results: The Westerlund cointegration confirmed that the variables are cointegrated. The panel fully modified least squares (FMOLS) and the fixed effects estimation results show that poor governance (corruption) induces adult mortality in most of the panels. However, good governance (political stability) reduces mortality among children under five and adults in all four panels.
Conclusion: The study supports the hypothesis that governance has inordinate consequences on under-five and adult mortality and therefore it has a huge impact on the health outlook of a population. The findings indicate that health expenditure and urbanization affect health outcomes in lower, upper, and high-income countries in changing economies. Different policy implications are therefore offered based on the study outcome.

Коммерциялық ұйымдар өздерінің бәсекелестік артықшылықтарын сыртқы және ішкі ақпаратты пайдалану негізінде анықтай алады. Басқару шешімдерін қабылдауды бухгалтерлік-аналитикалық қамтамасыз етудің негізі ретінде бухгалтерлік есепті жетілдіру арқылы нарық жағдайларына сәтті бейімделуге болады. Бухгалтерлік есептің келешекті және тез дамып келе жатқан бағыттарының бірі-стратегиялық есеп. Шетелде стратегиялық басқару есебі дәстүрлі түрде басқару есебі үшін ең маңызды технологиялардың бірі ретінде қарастырылады.
Мақалада стратегиялық басқару есебінің теориялық негізін зерттеу, əр түрлі ғалымдардың пікірлеріне сараптама жүргізілген, басқару есебінің мəні ашылып көрсетілген. Кəсіпорынды басқару жүйесінде басқару есебінің алатын орны айқындалған. Жалпы басқару есебінің теориялық мəні мен оның кəсіпорынды басқаруда алатын орнын анықтау қажеттілігі тақырыптың өзектілігі болып табылады. Бүгінгі таңда шығындар мен кəсіпорын қызметінің қаржылық нəтижелерін басқару саласында екі негізгі мəселе бар. Біріншісі, қазіргі экономика жағдайында отандық есеп жүйесінің теориясы мен тəжірибесін кəсіпорынды басқару мəселесі алдында тұрған жаңа міндеттерді орындауға қайта бағыттау. Екіншісі, шығындар туралы ақпарат алудың бейімделген жүйесін құру, өзіндік құнды калькуляциялаудың, қаржылық нəтижелерді есептеп шығарудың жаңа амалын, сонымен қатар талдау мен бақылаудың əдістерін қолдану жəне осының негізінде тиімді басқару шешімдерін қабылдау. Осыған байланысты кəсіпорындар үшін басқару есебі жүйесін жете зерттеу аса мəнге ие екендігі аталып өтіледі.
