Authors: Suryadi Awel , Rahman Fuad Ardani
Published: June 2023

According to the national port master plan, Tegal Port is a hub port. In practice, a number of fishing boats crowd the port pool area thereby disturbing the area that should be used for the port loading and unloading process. Full port facilities are not supported by this circumstance. Commercial ships wishing to enter the port must wait for the tide to enter the waters of the port pool because shipping lanes enter the port wisely around 3 LWS. This study aims to examine the relationship between the port facility utilization index and the port facility performance index in several categories of capacity accessibility and satisfactory performance levels, in the categories of safety, order, smoothness and speed, and pollution experienced unsatisfactory performance. This research uses a descriptive method. Data obtained from surveys and analyzed using the SWOT method. The SWOT analysis shows strength-opportunity (SO) conditions where managers must maximize the potential of ports that have facilities. The results of the SWOT analysis show that the right strategy to use for port development is strength-opportunity, namely improving existing facilities as well as possible, such as making repairs to facilities that are not suitable for use and adding facilities at the port and increasing cooperation with stakeholders by making more work agreements, promising and facilitating service users as well as cutting bureaucracy that does not complicate service users.
Review of Outdoor Air Pollution in Sri Lanka Compared to the South Asian Region
Authors: Rathnayake L.R.S.D. , Sakura G.B. , Weerasekara N.A.
Published: June 2023

Air pollution is a significant issue that affects almost all the countries in the world while predominating in South Asian Regional countries due to poverty, less attention, and less awareness towards the implementation and obeying of air quality guidelines in public. As a developing country, Sri Lanka stands at an optimum state of national air quality compared to other SARC because it is an island with a minor population compared to India, Pakistan, Bangladesh, etc. Maldives and Bhutan lie straightforwardly in owing mild air quality in SARC. However, SARC is far behind the world in maintaining optimistic air quality nationwide. Ambient air pollution-attributable deaths have become interim in past decades, a severe burden to the sustainable existence of SARC. A well-established systematic epidemiological, empirical studies and revisions regarding air pollution, strategic planning for mitigating air pollution, and frequent Spatio-temporal pollution monitoring nodes are necessary for Sri Lanka to achieve the sustainable goal. Other South Asian countries: India, Bangladesh, Pakistan, Afghanistan, Nepal, Bhutan, and Maldives, also should pay attention to minimizing outdoor air pollution nationwide for the betterment of future existence.

Authors: Vidhya L. , Vinodha S. , Pradeeba S. J. , Jeyagowri B. , Nirmaladevi V. , Nithiya N.
Published: June 2023

In the current research work, the authors proposed a list of tactics to eliminate Cr (VI) with the help of pig bone biochar. The Cr (VI) was adsorbed in batches onto pig bone biochar to scrutinize the adsorption data. The studies determine the impact of adsorption dose, pH, and concentration. From the results, it was inferred that the optimum pH level was 7 for the removal of metal. The study calculated the adsorption isotherms in terms of affinity and adsorption capacity by leveraging Temkin, Langmuir, and Freundlich equations. According to the reports, the Langmuir model is suitable for the adsorption data, followed by Temkin and Freundlich equations. In this model, rapid adsorption kinetic rates were observed, whereas the equilibrium state was achieved after two hours. There seems to be a perfect collation between the kinetic adsorption data and the pseudo-second-order equation. The researchers determined both Lagergren and Ho’sconstants. When biochar was characterized with SEM (Scanning Electron Microscope), EDX (Energy Dispersive X-ray spectrometer), and FTIR (Fourier Transform Infrared spectrometer), it was revealed that the Cr (VI) ions interacted with the isolated aggregates formed on the biosorbent surface. From the results, it can be understood that the pig bone biochar can be effectively used to eliminate chromium ions from an aqueous solution.

Authors: Salauddin A. , Sandesh C.
Published: June 2023

Heavy metal contamination is one of the significant concerns of environmental pollution. The present study was conducted to find out the correlation between soil and crop/food matrices grown at the exact location for Al, As, Ca, Cd, Cr, Cu, Fe, Hg, K, Mg, Mn, Ni, Na, P, Zn, and Pb elements near the industrial areas of Narol, Changodar, Vatva, Makarpura, Nandesari, and Ankleshwar in Gujarat, India. Soil samples were collected from 64 sampling sites in an industrial area. Twenty of these sites contained crop/food matrices used for the correlation study. The ranges of concentration of Cr (17-74.4 mg.kg-1), Cu (9.6-82.4 mg.kg-1), Ni (10.6-55.9 mg.kg-1), Pb (4.5- 20.7 mg.kg-1), Zn (21.5-112.4 mg.kg-1), and Al (7075-44557.5 mg.kg-1) for Soil and for crop Cr (0.3-0.6 mg.kg-1), Cu (0.3-8.6 mg.kg-1), Zn (1.1-43.5 mg.kg-1), Fe (12.6-69.4 mg.kg-1), and Al (5.8-102.2 mg.kg-1). According to the study, there is a strong correlation between the soil and crop/food matrices at the different locations, like 0.97 for Fe and Ni, 0.94 for Mg, 0.95 for Mn, and 0.55 for Pb and Zn, and very little correlation between K, P, and Ca, while a negative correlation between Al, Cr, Cu, and Na. The DTPA extractable method was used for the elemental analysis, and analysis was done using the ICP-OES instrument following microwave-assisted digestion. The results show that metal contamination transforms from soil to crop/food matrices, which represents a serious concern and requires action to address the metal contamination by industrialization.

Published: June 2023

Wastewater treatment necessitates the use of an appropriate method to achieve satisfactory results. The conventional method of Alum addition has been widely used for years, but it is prohibitively expensive. This study uses Moringa oleifera, an inexpensive and readily available plant, as a natural coagulant to treat wastewater collected from university dormitories. Physicochemical parameters such as pH, Turbidity, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Dissolved Oxygen (DO) were examined based on appropriate standards. Wastewater treatment with varied coagulant dosages of 50, 100, and 150 mg.L-1) was monitored using a standard jar test device with an initial wastewater perturbation at 100 rpm for 5 min was reduced to 50 rpm in 10 minutes with a rest time of 30 min. The results showed that the quality of the physicochemical properties of the water improved. The percentage increase in the water quality is; BOD (92%), COD (92%), and TDS (52-64%), with an increase in Moringa coagulant achieving a reduction of 96% of Turbidity. While the DO improved (79%), the pH remained below acceptable limits (6.73-7.56) for effluent disposal. The treated water showed clarity (colorless) and no odor compared to the wastewater. Hence, Moringa oleifera seeds cake residue can be an effective coagulant for wastewater treatment.

The Impact of High-Concentration Salt Solution on Morphological Changes in a Geosynthetic Clay Liner
Authors: Nisha N. P. , Jose J. Prakash Arul
Published: June 2023

Microscopic examination was used to begin investigating the changes in geosynthetic clay liner (GCL) specimens that had been hydrated with two separate solutions: pure water and a 50 percent concentration NaCl solution. After already being hydrated with NaCl aqueous solution, the GCL samples were examined under an electron microscope. Even though the treated GCL samples’ surfaces mirrored those of the untreated GCL, a crystal deposit was found there. It was found that the bentonite particles in the GCL sample appeared more solid after being hydrated with distilled water as opposed to the NaCl solution using a scanning electron microscope (SEM). It seems that wetting the salt solution decreases the bentonite particles’ tendency to swell. Additionally, it was demonstrated by the energy-dispersive X-ray spectrometer (EDS) data that distilled water hydration had no impact on the distribution of the elements identified in the GCL samples. On the other hand, the presence of bound chlorine demonstrated that the bentonite particles had absorbed the NaCl solution. The hydrated GCL sample’s hydraulic conductivity showed some variation as well.
Assessment of Sodium Chloride (NaCl) Induced Salinity on the Growth and Yield Parameters of Cichorium intybus L.
Authors: Khan A. , Khan A. A. , Samreen S. , Irfan M.
Published: June 2023

The present study was done on the hypothesis that excess sodium chloride (NaCl) in the soil decreases the growth and yield of Cichorium intybus L. To investigate this hypothesis, a pot experiment was conducted in which chicory seeds were sown in garden soil-filled earthen pots and treated with three different doses of sodium chloride (45, 75, and 105 mM kg-1 soil) except the control, and each treatment was replicated three times. The results revealed that all the saline treatments significantly (p≤0.05) reduced the vegetative (including root and shoot length, dry weight, number of leaves, leaf area, number of branches, and photosynthetic pigments) and reproductive (mean fruit number/plant, mean seed number/fruit, and total seed yield/plant) growth parameters of Cichorium intybus. On increasing NaCl concentration in the soil, chlorophyll content significantly (p≤0.05) decreased while proline content in the fresh leaves increased significantly (p≤0.05). From the results, it is concluded that Cichorium intybus L. can tolerate a moderate level of sodium chloride stress (45-75 mM NaCl kg-1 soil) but is sensitive to high doses of sodium chloride stress (105 mM NaCl kg-1 soil).

Published: June 2023

Arsenic, aluminum, iron, lead, chromium, copper, zinc, manganese, and cadmium are some of the heavy metal pollutants in the air that cause severe impacts on the biotic and abiotic environment. This study intended to find the accumulation capacity of the heavy metals on the leaves of tree species such as Terminalia catappa, Syzygium cumini, Saraca asoca, Pongamia glabra, and Ficus religiosa and predict their accuracy by comparing different machine learning (ML) models. The samples were collected at six different locations (likely Vellagate, Cancer Institute, CSI hospital area, Moongilmandapam, Collectorate, and Pallavarmedu) and distributed in a manner within Kanchipuram town, Tamil Nadu, in February and March of 2018 and 2019, respectively. Six ML methods were selected, such as KStar (K*), Lazy IKB, Logistic Regression Algorithm (LR), LogitBoost Classifier (LB), Meta Randomizable Filtered Classifier (MRFC), and Random Tree (RT), for prediction and to compare the efficiency of their predictions. Out of six models, Logistic functions perform well in terms of TP rate when compared to other classifiers (93.21%-99.81% TPR– 0.93–0.99) and Logitboost attained a low TP rate that ranged from 0.76 to 0.82. This study indicates the feasibility of different ML methods in the prediction of species capabilities toward the accumulation of heavy metals.

Published: June 2023

The present study collected anaerobic sludge from a paper mill operating a UASB reactor on agro-based raw material (wheat straw) washings for biogas production. After determining the sludge profile and methanogenic activity of anaerobic sludge, it was further used to determine the anaerobic biodegradability of RCF-based kraft paper mill effluent. The sludge profile of collected anaerobic sludge was found w.r.t. Suspended Solids (SS) 60 g.L-1, Volatile Suspended Solids (VSS) 23 g.L-1, Inorganic content 62% & Organic content 38%. The presence of effective microbes in anaerobic sludge was confirmed by SEM (Scanning Electron Microscope). Degradation of organic matter present in effluent by anaerobic digestion leads to the production of biogas (methane & CO2), a renewable energy source. The sludge profile and methanogenic activity findings supported the anaerobic treatment of kraft paper mill effluent and were positive. The methanogenic activity of anaerobic sludge was determined as 0.832 gCOD.gVSS-1×Day, and the average anaerobic biodegradability of RCF-based kraft paper mill effluent was found to be 71.5%.

Authors: Jadhav Abhijit S. , Nalawade Ravindra
Published: June 2023

Good quality activated charcoals were prepared from areca nutshell and coconut shell using phosphoric acid as a chemical activating agent at 400oC. Physico-chemical properties like iodine number, methylene blue number, and surface area of two activated charcoals were measured to assess the porous nature. A special test called acetic acid number was devised to understand the quality of functional groups on charcoal surfaces. Proximate analysis and physical properties of the two activated charcoals closely matched those of a commercial sample, confirming the good quality of samples prepared in the laboratory. Adsorption of isolated caramel from waste stream obeyed Freundlich isotherm, and the data could be explained based on the physisorption of large size molecules on the walls of mesoporous solid surface. Adsorption of methylene blue involving Coulombic attraction towards the areca nut shell-derived activated charcoal could be predicted and confirmed based on the acetic acid number for the first time.
Denaturing Gradient Gel Electrophoresis (DGGE) Analysis Indicating Increased Microbial Diversity in Landfill Area Near Conserved Wetland
Authors: Chakraborty M. B. , Patgiri S. R. , Rahman A. S. , Dasgupta A. , Pegu G.
Published: June 2023

The ecological balance of an ecosystem has a relation to its biodiversity. Although it has been established that biodiversity and ecological stability are related, generalization about the exact nature of this relation remains elusive and more so in microbial diversity. A growing volume of studies has indicated that anthropogenic activities impact biodiversity, but it is difficult to generalize the impact of anthropogenic activities on microbial diversity. Landfilling by municipal solid waste is one such activity where microbes play a major role, and leachates are released from the landfill, altering the soil’s physical and chemical nature. Change in factors like carbon source, pH, and toxicity of the soil is most likely to affect the indigenous microflora of the soil. The present study was undertaken to compare the microbial diversity of soil receiving landfill leachate with that of the soil not receiving any landfill leachate to assess the impact of the landfilling activity on microbial diversity. The landfill site selected for the study was that of Kamrup Metro District of Assam, located at Boragaon, near the Ramsar wetland called Deeporbeel. By using the Denaturing Gradient Gel Electrophoresis (DGGE) method, it has been found that the microbial diversity of the soil receiving leachate was higher than that of the soil not receiving any leachate from the landfill.

Published: June 2023

Construction activities produce considerable environmental effects and have resulted in a growing demand to implement favorable environmental practices. In this sense, this research aimed to evaluate the effect of the level of compliance with environmental regulations in public civil works in the San Ignacio, Cajamarca, Peru district. Data were obtained through direct observation and structured interviews in 7 selected construction sites. The deductive and analytical method was used. As a result, the level of compliance was obtained. Work 4 had the highest rank, and works 2 and 5 had the lowest. Currently, all the works are in a similar range of compliance. The degree of association between the level of compliance with environmental regulations and the current state of the civil works indicates a probability of 0.0190, which shows that the low level of compliance with environmental regulations in the construction of public civil works in the district of San Ignacio generates a deterioration in the quality of the environment and increases the possibility of administrative sanctions.

Padres de la Iglesia, filosofía pagana y configuración de la identidad cristiana. ¿Un auténtico diálogo entre la fe y la razón?
Authors: Bueno Ávila Antonio
Published: June 2023

El presente artículo estudia la relación entre el cristianismo y la filosofía pagana. Son muchos los cualificados estudios que han abordado esta cuestión con rigor y precisión. Desde el marco que nos ofrecen estas investigaciones, este trabajo analiza una cuestión más específica. Concretamente, examina el papel que ha desempeñado la filosofía pagana en la configuración de la identidad cristiana. Todo ello, sin olvidar la necesaria referencia a la herencia judía.  Para conseguir este fin, el estudio se divide en tres partes: 1) Diálogo patrístico; 2) Diálogo con la filosofía pagana; 3) Diálogo entre la fe y la razón. De este modo, se podrá concluir que el cristianismo, al mismo tiempo que se diferencia del judaísmo y el paganismo, no se puede entender sin la influencia de ambos. Desde esta tensión, se irá configurando, poco a poco y sin caer en un mero sincretismo, la identidad cristiana.
Paisagem urbana e sociedade do espetáculo: Entre vias, fachadas e letreiros em áreas comerciais de Montes Claros/MG
Authors: Gomes João Marcos Agapito Rabello , Santos Gustavo Souza
Published: June 2023

A paisagem urbana é um esteio de vestígios sócio-históricos e espaciais, constituindo as tramas, tessituras e afetos da cidade e seus sujeitos. O consumo e os fluxos produtivos do capital adicionam camadas vivenciais intempestivas sobre a paisagem urbana, coproduzindo a cidade e seus atores. Entre vias, fachadas, letreiros e práticas de consumo, deslizam ideários urbanos e platitudes que espetacularizam seus sentidos e mercantilizam seus processos. Analisa-se aqui as relações entre a produção da paisagem urbana, a estetização do consumo e o discurso publicitário na percepção do espaço e suas dinâmicas de sociabilidade em áreas comerciais centrais da cidade de Montes Claros/MG. Inicialmente, discute-se a produção do espaço urbano sob a lógica do consumo e, a seguir, partindo da premissa da estetização publicitária e socioespacial, discute-se o espetáculo urbano do comércio como potências de manutenção do capital que geram estruturas de manutenção do capital e assujeitamentos citadinos, com base em etnografia urbana aplicada.

Intelligent technology development is gaining traction in the sphere of education. The increasing rise of educational data suggests that standard processing methods may be limited and distorted. As a result, rebuilding data mining research technologies in the education industry has become necessary. Becoming more visible To avoid erroneous assessment findings and to anticipate students' future performance, this research analyses and predicts students' academic achievement using applicable clustering, discriminating, and convolution neural network theories. To begin, this work suggests that the clustering-number determination be optimized by employing a statistic that has never been employed in the K-means approach. The clustering impact of the K-means method is next assessed using discriminate analysis. The Convolutional neural network is presented for training and testing with labeled data. The produced model can be used to forecast future performance. Finally, the efficacy of the constructed model is tested using two metrics in two cross validation procedures in order to validate the prediction findings. The experimental findings show that the statistic not only addresses the objective and quantitative problem of determining the clustering number in the K-means method, but also enhances the predictability of the outcomes.
A SURVEY ON MEDICAL AND DISEASES PREDICTION USING MACHINE LEARNING

Machine learning is a subfield of AI and computer science that seeks to mimic human learning by enhancing its accuracy via exposure to more data and more complex algorithms. To improve software's predictive abilities, it doesn't need to be expressly coded to use machine learning (ML). Predictions from machine learning algorithms are based on past data. Machine learning has the ability to shake up the healthcare sector by providing novel approaches to managing healthcare data, reshaping patient treatment, and reducing back-end administrative tasks. Medical professionals and hospital administrators may benefit financially from the use of machine learning to deliver data-driven clinical decision support (CDS). Better health outcomes can be achieved with the help of machine learning thanks to increased patient participation in the treatment process. When applied to the IoMT, ML can collect more precise patient data and automate message alerts that prompt patients to take action at just the right time.
A SURVEY ON EFFICIENT AUDITING SCHEME FOR SECURE DATA STORAGE IN FOG-TO-CLOUD COMPUTING
Authors: A.Thenmozhi  , Dr.D.Vanathi
Published: June 2023

With the rise of the Internet of Things, fog-to-cloud computing has emerged as a new cutting-edge approach (IoT). Except for the cloud service provider, fog-to-cloud computing necessitates the participation of additional entities, such as mobile sinks and fog nodes (CSP). As a result, fog-to-cloud storage integrity audits will differ from standard cloud storage auditing. Tian et al. has completed the first stage in developing a public auditing system for fog-to-cloud computing. However, because they employ complex public key cryptography techniques like bilinear mapping and proof of knowledge, their system becomes inefficient. We offer a more broad and efficient auditing system based on MAC and HMAC, two prominent private key cryptography algorithms in this study. By implementing MAC and HMAC, we give a real instantiation of our auditing system. Finally, theoretical analysis and actual findings show that our suggested system has lower communication and computing costs.

La prima de la tarifación en un seguro para el sector salud está influenciada por la siniestralidad de sus suscriptores, lo que genera altos niveles de fluctuación e incertidumbre. El objetivo de esta investigación es la aplicación de los modelos actuariales riesgo individual, riesgo colectivo y modelo de credibilidad, junto con la aplicación del modelo tecnológico de tasa de falla y el modelo de opciones financieras de Black-Scholes como herramientas de estimación de la prima de la tarifación para la industria aseguradora y de la salud en Colombia. A partir de las reclamaciones y de los costos totales de los siniestros históricos se aplican los modelos que permita asegurar primas óptimas para una cobertura a las pérdidas agregadas de los siniestros. Al final, se comparan dichos modelos y se aproxima a una definición de un método óptimo. La importancia de la investigación radica en el alto compromiso, responsabilidad e incidencia financiera de gestionar y mitigar el impacto del riesgo actuarial, planteando nuevas metodologías mediante un nivel de estimación óptima en las primas para certificar un correcto funcionamiento a las entidades del sector en temas de costos, sostenibilidad y cumplimiento al servicio en el sector.

This research study aims to obtain empirical evidence to the influence of company characteristics (firm size, profitability, leverage and liquidity) and good corporate governance (audit committee, board size, and public ownership structure) toward the risk management disclosure. This research study uses the Index of Enterprise Risk Management (IERM) as the parameter of risk management disclosure. This research study uses secondary data, the population of Property and Real Estate companies listed on the Indonesia Stock Exchange (IDX) in 2013-2015. The sampling technique was conducted using purposive sampling, which produces 70 listed companies’ samples during the years of observation. The analytical method of this study uses multiple regression analysis of Econometric views 8. This research study concludes that partial testing shows that firm size, audit committees and board size are positively and significantly related to risk management disclosure. Profitability, leverage, liquidity have no significant influence on risk management disclosure. Hypothesis testing uses multiple linear regressions. Data are obtained using Eviews version 8 software application. Data analysis model done with multiple regression model aiming to examine the influence of audit committee size, board of commissioner size, firm size, profitability, and leverage toward risk management disclosure
Based on the research study result that has been analyzed statistically using multiple linear regressions, it can be concluded that variables of firm size, leverage, audit committee, and board of commissioner size positively and significantly affect corporate risk management disclosure.  Meanwhile, variables of profitability, liquidity, and public ownership do not positively and significantly affect risk management disclosure.

Published: June 2023

Estudio de Economía Política, Macroeconomía y Economía Aplicada basado en el enfoque de la Escuela Austriaca sobre los ciclos económicos para aplicarlo al caso español (2002-2014). Se centra la atención en el problema endémico de los ciclos económicos, como periodos sucesivos y distorsionadores de auge y recesión que sufren las economías desarrolladas, como la española. Esta investigación busca encontrar evidencia empírica a favor de la Teoría Austriaca del Ciclo Económico, para el caso concreto de España entre 2002 y 2014, mediante la aplicación de métodos econométricos. En consecuencia, tras revisar la escasa literatura econométrica previa sobre el ciclo austriaco, este estudio tiene como principal objetivo el explicar e ilustrar el auge con la introducción efectiva del euro en 2002, la recesión de 2008-10 y la recuperación de 2014, a la luz de la teoría austriaca del ciclo monetario endógeno y no neutral.
Modelo CAPM para la valoración de acciones de las empresas en el mercado de la construcción durante el periodo 2015 - 2020
Authors: Ossa González Genjis Alberto , Rojas Dominguez Miriam
Published: June 2023

El presente artículo consiste en la aplicación del modelo CAPM sobre las empresas que cotizan en la bolsa de valores y están relacionadas al sector de la construcción en Colombia durante el periodo del 1 de enero del 2015 hasta el 31 de diciembre del 2020. Esta investigación tiene un enfoque cuantitativo con un tipo de investigación descriptiva y longitudinal. Su metodología consistió en la aplicación de mínimos cuadrados ordinarios a las volatilidades diarias del activo en función de la estimación de los betas, los cuales cumplieron en su mayoría con los valores probabilísticos y los interceptos no eran diferentes de 0, lo que es coherente con la hipótesis del modelo. En cuanto a las variables que acompañan el modelo se escogió la tasa libre de riesgo TFIT16240724 y como variable que mide el riesgo de mercado al índice ICOLCAP. Finalmente, obtenidos los resultados, estos fueron evaluados, concluyéndose que el coeficiente beta es un indicador aceptable en la valoración riesgo-rentabilidad del activo durante el periodo en cuestión, más sin embargo como estimador no es efectivo, lo que refleja la poca eficacia del modelo.

The allogeneic hematopoietic stem cell transplant (allo-HCT) represents an important therapeutic strategy for acute leukemias, lymphomas and solid neoplasms, also used in benign diseases, such as aplastic anemia and inborn errors of immunity. This treatment requires myeloablative chemotherapy (conditioning regimen) followed by the infusion of donor-derived hematopoietic stem cells. However, this procedure carries some risks, such as infections, graft versus host disease (GVHD) and conditioning toxicity, which  may result in transplant-related mortality. Over the decades, due to the increasing life expectancy and new advances in medicine,  the cases of patients > 50 years with hematologic diseases that need allogeneic transplant  have grown, requiring a comprehensive geriatric assessment as a mechanism for  the best treatment option choice.

Objective: To apply a clinical frailty score and Karnofsky score in allogeneic hematopoietic stem cell older than 50 years old for three years in Walter Cantídio University Hospital (Fortaleza/Ceará) and in Amaral Carvalho Hospital (Jaú/São Paulo), expecting to recognize the profile of this patients and to demonstrate the relation between the clinical frailty score and overall survived, besides to estimate the contribution of GVHD prophylaxis and relapse in overall survival. Methods: Multicentric, retrospective, descriptive, analytical and quantitative study, acquiring dates by means of exams and medical record from Walter Cantídio University Hospital in Fortaleza/Ceará and Amaral Carvalho Hospital in Jaú/São Paulo. Results: The study selected 252 patients, 147 males and 105 females, sort in gender, disease, HCTCI score, CFS and KPS. In three years, the overall survival in FIT score is 2,46 years, while in FRAILTY score is 1,82 years. About the prophylaxis, the combination of cyclosporine, mycophenolate mofetil, cyclophosphamide had worse results than others prophylaxis. As expected, in case of relapse, there is shorter survival. Conclusion: The elderly population require a geriatric score in order to evaluate the profile of this patients once the allogeneic transplant must happen, then FIT patients has longer survival than FRAILTY patients.
