Authors: Ramezankhani Ali , Bahrambeygi Fatemeh
Published: March 2024

One of the Global strategies to accelerate the elimination of cervical cancer is vaccinated with HPV vaccines by age 15 years by 2030. Recent studies showed that increased vaccine-related knowledge associated with HPV-vaccine acceptance and intention to vaccinate. In other words, insufficient information is the main barriers to vaccination acceptance. Accordingly, interventions that improve understanding of HPV vaccines may increase HPV vaccination coverage. The aim of this study was to summarize educational interventions designed to increase HPV vaccine acceptance in adolescents and their parents. We searched the databases of PubMed, Science Direct and Google Scholar on October-December 2020. We performed a literature search for published articles in English and searched relevant keywords (papillomavirus vaccines and knowledge, acceptance, intervention studies, communication, education). Our search was limited to studies targeting populations from Asian countries. Thirteen interventional studies performed in Asian countries met the inclusion criteria. Five studies used PowerPoint presentation and slide presentation as an educational intervention. Two studies applied written media that was an educational sheet that provided information on HPV vaccines. Two studies used social media and mobile for educational intervention. Two studies designed the educational intervention in 30 minutes and 1 hour lecture which following by question and answer. Two of studies conducted two educational interventions. First one was applied PowerPoint presentation and social media and the second one used lecture and group discussion. HPV vaccine acceptance is varied widely between studies across Asian countries. Increasing public awareness about HPV vaccines, will increase acceptance. Increasing acceptance, will lead to demand people for health policy makers to will introduce HPV vaccines into their national immunization program.

Authors: Eli-Cophie Divine , Annan Reginald Adjetey , Apprey Charles
Published: March 2024

BACKGROUND:

Soccer is a team sport with a high energy and aerobic capacity requirement to sustain alertness and stamina within the stipulated period of play and training. The study aimed at examining the effect of nutrient intake, nutritional status, and hemoglobin (Hb) levels on the cardiorespiratory endurance (CRE) of footballers in the Volta Region of Ghana.

METHODS:

Male soccer players (n = 194) from clubs in the Volta Region of Ghana were recruited to participate in this cross-sectional study. Dietary intake was determined using multiple 24-h recall, Hb levels by use of HemoCue, and maximum oxygen uptake (VO2 max) by Cooper test 12 min run. Descriptive, multiple regression, Pearson’s correlation, and independent samples t-test were performed on the data obtained using the SPSS software.

RESULTS:

Football players of mean age 18.6 ± 4.9 years had an average energy intake of 1374.9 ± 532.6 kcal/day with a deficit of about 1481 kcal/day. Anemia prevalence was 13.5%, and there was a positive correlation (r = 0.411, P < 0.001) between dietary iron and CRE. Calories consumed significantly predicted the VO2 max (F [1, 74] =16.360, P < 0.001) of football players. There was no significant difference in the VO2 max values among the various age groups. About 65% of players had a “very low” to “fair” VO2 max, and 30.4% and 3.8% of the players had “good” and “excellent” levels of VO2 max, respectively.

CONCLUSION:

The overall energy intake of football players in Ghana was associated with dietary iron intake, Hb levels, and CRE, but not enough to meet dietary requirements, support optimal health, and enhance athletic performance.
Malignant potential of neuroendocrine microtumor of the pancreas harboring high-grade transformation: lesson learned from a patient with von Hippel-Lindau syndrome
Authors: Lee Jongwon , Lee Kyung Jin , Hwang Dae Wook , Hong Seung-Mo
Published: March 2024

Pancreatic neuroendocrine microtumor (PNEMT) is a neuroendocrine tumor (NET) < 0.5 cm in diameter, and it is considered benign. We report a PNEMT with high-grade transformation (HGT). A man in his 60s with von Hippel-Lindau syndrome underwent surgical resection of a NET. A second sub-centimeter nodule with a nodule-in-nodule pattern was discovered. The 0.4 cm outer nodule contained clear columnar cells with round nuclei and indistinct nucleoli, while the 0.1 cm inner nodule had eosinophilic cells with an increased nuclear to cytoplasmic ratio, vesicular nuclei, and prominent nucleoli. Tumor cells in the outer and inner nodules were synaptophysin and chromogranin positive. Only the inner nodule was p53 positive, while the outer nodule was exclusively positive for carbonic anhydrase 9 and vimentin. The Ki-67 labeling indices for the outer and inner nodules were 2.1% (grade 1) and 44.3% (grade 3), respectively. This nodule was determined to be a PNEMT with HGT. Our findings suggest that a PNEMT may not always be benign and can undergo HGT.

Acute worsening of microvascular complications of diabetes mellitus during rapid glycemic control: The pathobiology and therapeutic implications
Authors: Blaibel Dania , Fernandez Cornelius James , Pappachan Joseph M
Published: March 2024

While chronic hyperglycaemia resulting from poorly controlled diabetes mellitus (DM) is a well-known precursor to complications such as diabetic retinopathy, neuropathy (including autonomic neuropathy), and nephropathy, a paradoxical intensification of these complications can rarely occur with aggressive glycemic management resulting in a rapid reduction of glycated haemoglobin. Although, acute onset or worsening of retinopathy and treatment induced neuropathy of diabetes are more common among these complications, rarely other problems such as albuminuria, diabetic kidney disease, Charcot’s neuroarthropathy, gastroparesis, and urinary bladder dysfunction are also encountered. The World Journal of Diabetes recently published a rare case of all these complications, occurring in a young type 1 diabetic female intensely managed during pregnancy, as a case report by Huret et al . It is essential to have a comprehensive understanding of the pathobiology, prevalence, predisposing factors, and management strategies for acute onset, or worsening of microvascular complications when rapid glycemic control is achieved, which serves to alleviate patient morbidity, enhance disease management compliance, and possibly to avoid medico-legal issues around this rare clinical problem. This editorial delves into the dynamics surrounding the acute exacerbation of microvascular complications in poorly controlled DM during rapid glycaemic control.
Periodontitis: An often-neglected complication of diabetes
Authors: Kudiyirickal Marina G , Pappachan Joseph M
Published: March 2024

The bidirectional association between type 2 diabetes mellitus (T2DM) and periodontitis is now well established, resulting in periodontal disease being considered as the 6th major complication of diabetes mellitus (DM) after car-diovascular disease, eye disease, neuropathy, nephropathy, and peripheral vascular disease. DM can worsen the virulence and invasiveness of pathogenic oral microbial flora aggravating the local inflammation and infection in those with periodontal disease. On the other hand, the chemical and immunological mediators released into the circulation as part of periodontal inflammation worsen the systemic insulin resistance with worsening of T2DM. Periodontitis if undiagnosed or left untreated can also result in eventual tooth loss. A study by Xu et al in the World Journal of Diabetes examined the predictive factors associated with periodontitis in Chinese patients with T2DM. The prevalence of periodontitis was found to be 75.7% in this study. Based on logistic regression analysis, the predictive factors for higher risk were low tooth brushing frequency [odds ratio (OR) = 4.3], high triglycerides (TG; OR = 3.31), high total cholesterol (TC; OR = 2.87), higher glycated hemoglobin (HbA1c; OR = 2.55), and higher age (OR = 1.05) while higher education level was protective (OR = 0.53). However, the most influential variables were HbA1c followed by age, TC, TG, low education level, brushing frequency, and sex on the random forest model (this model showed higher sensitivity for predicting the risk). A good understanding of the predictors for periodontitis in T2DM patients is important in prevention, early detection of susceptible patients, and intervention to improve periodontal health and enable long-term glycaemic control as observed by Xu et al .
Associations between Geriatric Nutrition Risk Index, bone mineral density and body composition in type 2 diabetes patients
Authors: Zhu Xiao-Xiao , Yao Kai-Feng , Huang Hai-Yan , Wang Li-Hua
Published: March 2024

BACKGROUND

Type 2 diabetes mellitus (T2DM), a fast-growing issue in public health, is one of the most common chronic metabolic disorders in older individuals. Osteoporosis and sarcopenia are highly prevalent in T2DM patients and may result in fractures and disabilities. In people with T2DM, the association between nutrition, sarcopenia, and osteoporosis has rarely been explored.

AIM

To evaluate the connections among nutrition, bone mineral density (BMD) and body composition in patients with T2DM.

METHODS

We enrolled 689 patients with T2DM for this cross-sectional study. All patients underwent dual energy X-ray absorptiometry (DXA) examination and were categorized according to baseline Geriatric Nutritional Risk Index (GNRI) values calculated from serum albumin levels and body weight. The GNRI was used to evaluate nutritional status, and DXA was used to investigate BMD and body composition. Multivariate forward linear regression analysis was used to identify the factors associated with BMD and skeletal muscle mass index.

RESULTS

Of the total patients, 394 were men and 295 were women. Compared with patients in tertile 1, those in tertile 3 who had a high GNRI tended to be younger and had lower HbA1c, higher BMD at all bone sites, and higher appendicular skeletal muscle index (ASMI). These important trends persisted even when the patients were divided into younger and older subgroups. The GNRI was positively related to ASMI (men: r = 0.644, P < 0.001; women: r = 0.649, P < 0.001), total body fat (men: r = 0.453, P < 0.001; women: r = 0.557, P < 0.001), BMD at all bone sites, lumbar spine (L1-L4) BMD (men: r = 0.110, P = 0.029; women: r = 0.256, P < 0.001), FN-BMD (men: r = 0.293, P < 0.001; women: r = 0.273, P < 0.001), and hip BMD (men: r = 0.358, P < 0.001; women: r = 0.377, P < 0.001). After adjustment for other clinical parameters, the GNRI was still significantly associated with BMD at the lumbar spine and femoral neck. Additionally, a low lean mass index and higher β-collagen special sequence were associated with low BMD at all bone sites. Age was negatively correlated with ASMI, whereas weight was positively correlated with ASMI.

CONCLUSION

Poor nutrition, as indicated by a low GNRI, was associated with low levels of ASMI and BMD at all bone sites in T2DM patients. Using the GNRI to evaluate nutritional status and using DXA to investigate body composition in patients with T2DM is of value in assessing bone health and physical performance.
Myosteatosis is associated with coronary artery calcification in patients with type 2 diabetes
Authors: Liu Fu-Peng , Guo Mu-Jie , Yang Qing , Li Yan-Ying , Wang Yan-Gang , Zhang Mei
Published: March 2024

BACKGROUND

Myosteatosis, rather than low muscle mass, is the primary etiologic factor of sarcopenia in patients with type 2 diabetes mellitus (T2DM). Myosteatosis may lead to a series of metabolic dysfunctions, such as insulin resistance, systematic inflammation, and oxidative stress, and all these dysfunctions are closely associated with the acceleration of T2DM and atherosclerosis.

AIM

To investigate the association between myosteatosis and coronary artery calcification (CAC) in patients with T2DM.

METHODS

Patients with T2DM, who had not experienced major cardiovascular events and had undergone both abdominal and thoracic computed tomography (CT) scans, were included. The mean skeletal muscle attenuation was assessed using abdominal CT images at the L3 level. The CAC score was determined from thoracic CT images using the Agatston scoring method. Myosteatosis was diagnosed according to Martin’s criteria. Severe CAC (SCAC) was defined when the CAC score exceeded 300. Logistic regression and decision tree analyses were performed.

RESULTS

A total of 652 patients with T2DM were enrolled. Among them, 167 (25.6%) patients had SCAC. Logistic regression analysis demonstrated that myosteatosis, age, duration of diabetes, cigarette smoking, and alcohol consumption were independent risk factors of SCAC. Myosteatosis was significantly associated with an increased risk of SCAC (OR = 2.381, P = 0.003). The association between myosteatosis and SCAC was significant in the younger patients (OR = 2.672, 95%CI: 1.477-4.834, P = 0.002), but not the older patients (OR = 1.456, 95%CI: 0.863-2.455, P = 0.188), and was more prominent in the population with lower risks of atherosclerosis. The decision tree analyses prioritized older age as the primary variable for SCAC. In older patients, cigarette smoking was the main contributing factor for SCAC, while in younger patients, it was myosteatosis.

CONCLUSION

Myosteatosis is a novel risk factor for atherosclerosis in patients with T2DM, especially in the population with younger ages and fewer traditional risk factors.
Regulatory role of peroxynitrite in advanced glycation end products mediated diabetic cardiovascular complications
Authors: Bala Asis
Published: March 2024

The Advanced Glycation End Products (AGE) binding with its receptor can increase reactive oxygen species (ROS) generation through specific signaling mediators. The effect of superoxide (O2-) and O2- mediated ROS and reactive nitrogen species depends on their concentration and location of formation. Nitric oxide (NO) has anti-inflammatory and anticoagulant properties and a vasodilation effect, but NO can be deactivated by reacting with O2-. This reaction between NO and O2- produces the potent oxidant ONOO−. Therefore, ONOO-'s regulatory role in AGEs in diabetic cardiovascular complications must considered as a regulator of cardiovascular complications in diabetes.

This work covers a numerical analysis of the design and optimization of a thermoelectric cooler (TEC) operated by a thermoelectric generator (TEG). The aim of the work was to design the optimum mini refrigerator for tractors and also to provide cooling using the energy produced in the TEG used in the tractor. Thanks to the TEC powered with the TEG system, farmers will be able to preserve their food during working hours without additional fuel consumption. When the literature is examined, no study has been found in which cooling is done by using the compressor air of turbocharged systems. Therefore, this work will make an important contribution to the literature. According to the numerical results obtained, while the electrical power requirement was 34.78 W at an outdoor temperature of 30 °C, it was 26.54 W at an outdoor temperature of 15 °C. In other words, while the coefficient of performance was obtained as 0.301 at 15 °C, it was determined as 0.219 at 30 °C. In addition, while the electrical power value produced by the TEG system used in the tractor for an outdoor temperature of 15 °C was 50.71 W, it was 38.84 W at an outdoor temperature of 30 °C.

The runoff and sediment produced from a river basin due to effective precipitation depends on the characteristics of its catchment. The catchment characteristic is site-specific and varies from basin to basin. It depends upon the topographic characteristics, climatic parameters, soil properties, geology, and human-induced activities of the catchment. Knowledge of these factors is essential for sustainable management of natural resources, i.e. soil and water and site-specific conservation measures of the basin or watershed. Morphometric parameters of the basin truly reflect the combination of all characteristics, and this is one of the major indicators for the hydrological behaviour of any watershed or catchment. For the present study, Pairi River sub-basin, situated between 81°51'58.7"- 82°26'16.04" E longitude to 19°55'51.9"- 20°55'6.9" N latitude, has been considered for the morphometric analysis using geospatial technique . Results of morphometric analysis revealed that the Pairi sub-basin has seventh order drainage network with a dendritic pattern. The dendritic drainage pattern of the subbasin shows that the basin has homogeneous lithology and a lack of structural control. The drainage density and stream frequency indicates that the sub-basin has a gentle slope and good permeability of sub-surface material. So, this sub-basin is suitable for constructing artificial groundwater recharge structures to improve the groundwater resource. The length of overland flow revealed that surface runoff may reach the stream more quickly within the sub-basin. The bifurcation ratio varies different successive stream orders. The mean bifurcation ratio is low, indicating that the geologic structure does not distort the drainage pattern and produces low to moderate peak flow in the subbasin. The shape parameters such as form factor, circulatory ratioand elongation ratio indicate that the sub-basin is elongated in shape, high infiltration capacity, and flatter hydrograph with low to moderate runoff. This study can be useful for developing and managing natural resources of the Pairi sub-basin, like site-specific soil and water conservation measures such as check dam, percolation tank, water harvesting structure and development and management of groundwater, etc

Soil characterization and classification is crucial to all soil studies, as it is an important tool for understanding the nature of soil along with successful transfer of research results from one study area to another. The proper understanding of the nature and properties of soil and their management based on their potential and problems is important for increasing crop production to the optimum level. For understanding the problems and potentials, detailed soil survey plays an important role which provides adequate information in terms of land form, slope, land use as well as characteristics of soils (viz., texture, depth, structure, stoniness, drainage, acidity, salinity etc.) which can be utilized for the planning and development. The purpose of the study is to classify the soils of Asavru sub-watershed in Mysuru district to categorize the soils into different soil order upto family level of Soil taxonomy Classification and enhance the productivity and profitability of the area. The detailed soil survey was carried out in Asvaru sub-watershed. Seventy two profiles were studied for its different morphology, physical and chemical properties. The subwatershed area was grouped into 75 mapping units consisting of 16 soil series. The soils were shallow to very deep with texture varying from sandy loam to sandy clay. The structure was sub-angular blocky in all profiles with friable consistency. Soil reaction varied from moderately acidic to moderately alkaline and non saline in +2 + + + nature. Exchangeable cations followed the pattern of Ca >Mg >Na >K . The soil series identified in the sub-watershed area were classified under different soil orders (Alfisols and Inceptisols) upto family level according to revision of Soil Taxonomy. Major proportion of the soils of the sub-watershed belonged to Alfisols (Pedons1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12 and 15) and Inceptisols (Pedon5, 13 and 16).

Authors: Waziz Wildan , Fitriani Fajar , Riko Aulia Rachman
Published: March 2024

One of the characteristics of the Dieng geothermal field is the high silica content in the production fluid which causes the appearance of silica scaling. The presence of silica scaling inhibits the energy extraction process and becomes waste that disturbs the environment. The silica scaling can be utilized as a nanosilica product for use as a reinforcing filler. Nano-sized powder is expected to improve the mechanical properties of a product with denser results. This research aims to synthesize nanosilica from geothermal scaling silica using the alkali fusion method. Nanosilica is obtained by reacting alkali KOH with silica scaling which has been reduced in size using ball milling. The fusion process is carried out using heat treatment at varying temperatures of 400, 450 and 500ºC. The fusion results were dissolved in distilled water for titration using 2M HCl with stirring using a magnetic stirrer until gelation was formed which was dried into silica nanoparticles. Characterization of the size of nanosilica powder using the Particle Size Analyzer (PSA) obtained the smallest size data at a fusion temperature of 400ºC with the size tending to increase as the fusion temperature increased, where these results were in line with the analysis of nanosilica images from Transmission Electron Microscopy (TEM) testing using ImageJ software. Compound analysis using Fourier Transform Infra-Red (FTIR) shows the presence of characteristic silica bonds. The results of X-Ray Diffraction (XRD) do not show sharp peaks so the compound has an amorphous phase.

The aim of this research is to determine the effect of engine performance (torque and power), as well as exhaust emissions after replacing the piston. Tests were carried out on a 200CC engine with flat piston specifications with a diameter of 65.0 mm and replaced with a convex piston with a diameter of 65.0 mm using pertalite fuel. The research results obtained by replacing the convex piston (dome) caused the volume of the combustion chamber to decrease resulting in increased torque and power. There was an increase in torque of 0.02607 ft-lbs and an increase in power of 41.95384 HP, then the compression ratio increased by 0.5%. In exhaust gas emissions containing CO, HC, O2, CO2 using a gas analyzer with the results of research on flat pistons and dome pistons, it can be seen that emissions from convex pistons (dome) have increased compared to flat pistons. with the highest increase in stationary of 6.17% in CO emission content due to incomplete combustion residue, which means that the type of piston has a significant influence on exhaust gas emissions. Then the exhaust gas emission test results also show an increase in the O2 emission content on the flat piston at RPM 5000 with a value of 4.24% due to the mixture of oxygen and fuel being more perfect, but on the convex piston (dome) there is a significant increase Compared to a flat piston only at RPM 6500 with a value of 4.53% in O2 emission content. The HC and CO2 emissions content shows unstable or changing values. Apart from that, variations in engine speed also affect the exhaust emissions produced.

TPACK mengacu pada pengetahuan yang mengintegrasikan tiga komponen utama yaitu pengetahuan teknologi, pedagogik dan konten/materi ajar. Penelitian ini bertujuan untuk menganalisis tingkat kemampuan TPACK calon guru vokasional yaitu, mahasiswa yang sedang melaksanakan Praktek Keterampilan Mengajar (PKM) di Sekolah Menengah Kejuruan (SMK) wilayah Jakarta. Metode penelitian menggunakan kuantitatif deskriptif dengan sample purposive sampling sebanyak 36 mahasiswa. Pengumpulan data menggunakan instrument dan observasi yang telah diuji validitas dan reabilitasnya berupa kuesioner penilaian dari guru pengampu (pamong). Hasil penelitian menunjukan bahwa kemampuan Technological, pedagogical and Content Knowledge (TPACK) calon guru vokasional secara kumulatif dalam kategori baik. Mahasiswa perlu untuk meningkatkan kemampuannya terkait pemahaman dan penerapan TPACK dalam mengajar untuk memenuhi tuntutan dari kompetensi guru. Hal ini memberikan gambaran positif terkait kemampuan mahasiswa dalam mengintegrasikan Teknologi, Pedagogik, dan Content dalam konteks pembelajaran vokasi, terutama pada komponen Pedagogik dan Konten.

Amoroso Costa foi um matemático brasileiro, falecido tragicamente em dezembro de 1928, em um acidente de avião no que seria uma homenagem a Alberto Santos Dumont quando do seu retorno ao Brasil. Ele se dedicou a estudos sobre Relatividade Geral, Geometrias não-euclidianas, Teorias de números e combateu o positivismo, doutrina predominante no Brasil Republicano do início do século XX. Arthur Gerhardt Santos, governador do Espírito Santo no início da década de 1970, se dedicou a estudar a vida e a obra deste importante pioneiro da ciência no Brasil. Este texto reproduz os elementos essenciais de uma conversa com Gerhardt Santos sobre Amoroso Costa. Foi uma ocasião para falar de vários outros assuntos paralelos como o positivismo, a ciência e a educação no Brasil.
Mapeamentos de galáxias
Authors: Moraes Bruno Azevedo Lemos
Published: March 2024

Neste artigo, abordamos o desenvolvimento dos mapeamentos de galáxias e a sua importância para a astrofísica extragaláctica e para a cosmologia. Acompanhando a evolução dos telescópios, instrumentos e técnicas de observação astronômica desde o século XIX, discutimos como os avanços tecnológicos permitiram desvelar propriedades fundamentais do universo, tal como sua dinâmica, composição e sua estrutura em grande escala. Os mapeamentos de galáxias também revelaram a presença de matéria escura em diferentes escalas e seu impacto tanto na topologia da teia cósmica quanto nos processos de formação e evolução das galáxias. Observações das diferentes propriedades das galáxias individuais e suas correlações espaciais induzidas pelo ambiente local fornecem evidências para testar diferentes modelos físicos da interação gravitacional e seu impacto nos processos energéticos que contribuem para moldar os diferentes tipos de galáxias e suas características. Simulações de n-corpos possuem um papel crucial na reprodução da formação e evolução das estruturas cósmicas, permitindo contrastar as observações com universos simulados e testar teorias e hipóteses sobre a dinâmica do universo e a formação de galáxias. Em suma, a análise da estrutura em grande escala e dos efeitos ambientais na formação e evolução das galáxias ilustram a conexão complexa entre a cosmologia e a astrofísica modernas e ressalta a importância dos mapeamentos de galáxias para melhor entendê-las, apontando para o potencial de descobertas futuras à medida que as tecnologias e métodos observacionais continuem a evoluir.

The way in which public procurement is carried out affects the whole economy and, indirectly, the quality of people’s live, as a result of public servcies, goods and works acquired. Free competition between tendering economic agents, equity and fairness of procurement tenders must to be guaranteed within the framework of digitalized business-oriented public services. These have to stimulate the development of the business environment by offering contract for supply of public goods, services and works in a framework of transparent, objective and fair competition. Digitalisation of public services offers an advantage in this respect. This present paper proposes an unitary architectural model of the public procurement process within local administrations, one that could serve as a basis for the design of adequate computer software aimed at providing digital formatting to this entire process. The model is unitary within each Romanian local public administration and is also applicable to any of its structures (city councils, regional councils or their subordinated public institutions, other entities financed from public funds) and has been drafted in compliance with the applicable public procurement legislation. Proposing this model is justified not only because it provides a unitary public procurement digitalization process of the contracting authority which, at the moment relies solely on the use of the SICAP national platform, but also because its implementation guarantees the compliance with the principles of free competition between tendering economic agents as well as impartiality and fairness during the tender selection process. Digitalisation provides this advantage to both the public and private sectors, enabling their interaction, an advantage that needs to be properly exploited to generate digitalised services with added value, customized for the business environment, the added value consisting in actually ensuring these principles.
SUSTAINABILITY PERFORMANCE INDICATORS
Authors:   Doctoral School of Economic Sciences, Faculty of Economic Sciences, University of Oradea, Romania, GÖNCZI József
Published: March 2024

Sustainable Balanced Scorecard (SBSC), Organizational Sustainability Performance Index (OSPI), and Corporate Sustainability Index (ISE) are all tools that help organizations measure and manage their sustainability performance. SBSC integrates sustainability considerations into traditional performance management systems, while OSPI and ISE provide sustainability performance benchmarks for organizations to assess their sustainability performance and identify areas for improvement. These indicators reflect a growing emphasis on measuring and managing sustainability performance in organizations and are likely to become increasingly important as stakeholders demand more transparency and accountability in sustainability reporting. Sustainable Management System (SMS), Environmental Management Accounting (EMA), Sustainability Management Accounting (SMA), and the Composite Index of Sustainable Development (ICSD) are all indicators that reflect the growing emphasis on sustainable practices and accounting frameworks in today’s business and economic. SMS helps organizations integrate sustainability considerations into their operations, while EMA and SMA provide tools for identifying and measuring the environmental and social costs and benefits of business activities. ICSD measures a country’s progress towards sustainable development based on various economic, social, and environmental indicators. These indicators suggest a growing recognition of the importance of sustainability in economic development and decision-making processes, and are likely to become increasingly important as organizations and governments continue to prioritize sustainability.

The study investigated the influence of organizational resources on implementation of strategic plans (SPs) in Tanzania’s Local Government Authorities. The idea behind was to establish the influence of available resources (financial, human, material and information) on implementation of SPs in LGAs. The underlying theory on this study was resource-based view. The study opted Pragmatism philosophy which hinges on the mixed methods approach (explanatory sequential design), and the study was a cross- sectional, where data were collected at one point in time. The sample size of 204 respondents was drawn from a target population of 860 employees in five randomly selected LGAs in Morogoro region. The findings revealed that, all predictors (financial, human, material and information resources) had a statistically significant positive relationship with the implementation of SPs in LGAs: Whereby, financial resources had (t=2.147, P=0.033<Alpha=0.05); human resources had (t=1.977, P=0.049<Alpha=0.05); material resources had (t=3.822, P=0.000<Alpha=0.05) and information resources had (t=4.783, P=0.000<Alpha=0.05). Also, the value of R2=0.335 indicated that, 33.5% of variation on the execution of SPs was influenced by all predictors in the model, thus other factors not included in the study model contributed 66.5% of implementation process in LGAs. The study recommends that, LGAs should allocate enough funds, quality employees, enough offices and facilities as well as improved ICT infrastructures for the successful implementation of their SPs.
