Early strength development of mortar with addition of calcium formate and electric field curing in cold climates
Authors: Yang Zhouzhou , Mao Jianghong , Li Bixiong , Li Sili , Qian Wei , Li Hao , Ren Jun
Published: June 2023

The rapid development of early strength of concrete in cold regions is the primary measure to ensure its resistance to frost damage. In this context, this paper incorporates 2 wt% calcium formate into a mortar and electrically cures it by passing an alternating current (AC) at a temperature of −10°C. During testing, a temperature probe monitors the real-time changes in the internal temperature of the mortar under different energisation parameters. The strength of the mortar energised for 1 day is analysed under different energisation parameters. Then, the mortar specimens are moved to a standard curing box to be cured for 3 and 7 days. X-ray diffraction (XRD), TG/DTG (thermogravimetry/derivative thermogravimetry), scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) characterise the hydration products, microstructure and pore structure of the electrically cured mortar specimens. The results show that the initial resistance of the mortar specimen with calcium formate is 25% of that of the mortar without calcium formate. The 3- and 7-day strengths of the calcium formate mortar increase by 59 and 29%, respectively, compared with the mortar without calcium formate under the same energisation parameters. The combined effect of adding calcium formate and applying electrical curing densifies the pore structure of the electrically cured mortar.

Published: June 2023

Analysis of statistics at the micro-level shows that the development trends of a large number of resident entrepreneurial structures of industrial parks are characterised by adverse dynamics. Accordingly, assessment of the performance of entrepreneurial structures and improvement of their management models in the general system of industrial parks become more relevant. This paper presents a methodological approach to the construction of a spatial-rating assessment of the performance of entrepreneurial structures in the system of industrial parks functioning. As a result, two groups of Russian regions were identified, among which a potential resident, when making a decision on the placement of production facilities, can choose a region taking into account its investment attractiveness and industrial activity. Two discriminant groups of industrial parks were determined, the condition of which can be defined as economically inefficient and efficient, by evaluating parks with low and high values of the park rating level in terms of attractiveness for external investors and resident entrepreneurial structures. The proposed methodological approach can be applied to improve the quality of decisions on the formation of differentiated strategies for sustainable development of both individual entrepreneurial structures in the system of industrial parks and their clusters, and regions as a whole. It is recommended for both enterprises and industrial parks when making decisions on the formation of strategies and development scenarios, as well as for federal and regional authorities when designing documents for the territorial development on the strategic and tactical level.
Dios en mi conciencia. La idea de Dios en Juan Ramón Jiménez
Authors: Gutiérrez-Pozo Antonio
Published: June 2023

La poesía de Juan Ramón Jiménez es una poesía religiosa sui generis. La obra poética de Juan Ramón implica un desarrollo evolutivo hacia Dios. Dios es en la realidad. No está más allá, sino en el mundo. La poesía de Juan Ramón conecta con el panteísmo y el misticismo al mismo tiempo. No se interesa por una idea universal y abstracta de la divinidad. Lo que pretende es entender su propia experiencia de Dios, su encuentro personal con él. Acceder a esa experiencia solo es posible si previamente se han eliminado todas las nociones artificiales inventadas y añadidas a aquel encuentro originario con Dios. Esta experiencia primaria y personal de lo divino reside en último término en su conciencia de la belleza. Dios está en la conciencia; es más, es conciencia. Dios, por tanto, está a la vez dentro y fuera de la conciencia del poeta.
El historiador es criatura de civilizaciones que se desintegran: una plática diacrónica entre Ernesto Volkening y Nicolás Gómez Dávila
Authors: Gómez-Arbeláez José Miguel
Published: June 2023

En este texto se examina el fructífero diálogo sobre la naturaleza de la historia consignado en el Diario de lectura que lleva Ernesto Volkening (1908-1983) sobre los Escolios de Nicolás Gómez Dávila (1913-1994). Entre escolios y comentarios se hila una concepción de la historia que, a pesar de ser fragmentaria, guarda una auspiciosa  coherencia. El historiador, el hecho histórico y el individuo son los conceptos centrales respecto a los cuales se compone el pensamiento histórico. Sin embargo, ese pensamiento solo se vislumbra en el diálogo entablado, pues los escolios se ven iluminados por los comentarios de Volkening: quien ante la etérea soledad del escolio suele proponer un acontecimiento histórico o un historiador como ejemplo.
Soplos tramontanos o voces inmanentes. El análisis religioso de la secularización en Nicolás Gómez Dávila
Authors: Gómez Rodas Carlos Andrés
Published: June 2023

En la obra de Gómez Dávila, se manifiesta una genuina teología política, un análisis religioso de la política. El artículo se enfoca en algunas fuentes teológicas del pensamiento moderno desde la óptica de Gómez Dávila, con miras a comprender el proceso de secularización como fenómeno político distintivo de la Modernidad. Para ello, en primer lugar, se explica la importancia del siglo xiii como siglo de rupturas en la cosmovisión católica a partir de la influencia del pensamiento de Averroes. En segundo lugar, se muestra cómo las ideas averroístas tienen eco en Pascal y en el Romanticismo, para ubicar a Gómez Dávila en la disputa averroísta. Por último, se presenta la conclusión, cuya idea principal es que, para Gómez Dávila, solo un fideísta y místico medieval es genuinamente reaccionario, pues el diálogo fe-razón tomista subyace tras la concepción moderna de la política.
Crearse a sí mismo en la escritura. Aspectos filosóficos de la obra ensayística de Hernando Téllez
Authors: Serrano López Federico Guillermo
Published: June 2023

El presente artículo pone en alto los aspectos filosóficos de la investigación sobre sí mismo que realizó el escritor Hernando Téllez (1908-1966) en su obra ensayística. Esto permite señalar la condición híbrida y abierta del género ensayístico, la cual hace posible situar la reflexión de Téllez en un espacio indiscernible entre la literatura y la filosofía con un mutuo enriquecimiento de estas dos formas de pensamiento. A partir de lo anterior, se concluye que es necesario reinterpretar el período previo a la profesionalización de la filosofía en Colombia, ya no solo como un lapso de tránsito a la modernización, sino como un momento de la reflexión literaria y filosófica con sus propias gramáticas de creación, relacionamiento y  divulgación del pensamiento.

Authors: BAĞDA Esra
Published: June 2023

In the present study a new kinetic catalytic method was developed for the sensitive determination of selenium in pharmaceutical formulations. The reaction between basic blue 3 (BB3) and sulphide catalysed by Se (IV) in the presence of acetic-phosphoric-boric acid buffer system. The decrease in the absorbance at 654 nm indicated the reduction of BB3. The presence of selenium (IV) accelerated the reaction rate. The method based on the linear correlation between amount of Se(IV) and reaction rate. Under optimum conditions, the linear calibration range was found as 0.1-2.0 µg ml-1 by the fixed time method for the 0.5-5 min. The tolerance limits of various species was also studied. The interfering effect of some cations such as Cr3+, Fe3+, and Hg2+ was reduced with using cation exchange resin. The proposed method was successfully applied to spiked nasal spray and veterinary drug samples. Besides, total selenium, Se (IV) and Se (VI) speciation also conducted with reducing Se (VI) to Se (IV) with HCl in the synthetic mixtures.

Published: June 2023

In this study, the physicochemical properties and antioxidant activities of the commercially produced 15 pomegranate sour samples and one control sample were determined and their compliance with the TS 12720 (traditional sour pomegranate concentrate standard) was evaluated. Antioxidant activity values of pomegranate sours extracts were determined using 6 different methods. The samples had strong antioxidant capacity, except for N10 and N15. In addition, glucose, fructose, sucrose, HMF and acidity measurements of the same samples did not show compatibility with TS 12720. The pH values of the samples of N7, N8, N10, N11, N14 and N15 were not in accordance with the standard values (2.4-4.0) The titratable acidity values measured in samples of N1, N3, N4, N6, N10, N13, N15 were below the value (>6.0% (m/m)) in the standard. While the brix values of the samples were measured between 59.20-75.70, the brix values of the N12, N13 and N14 samples were determined below the standard brix value (>68%). The highest HMF value of the samples were determined as 8117.66. According to TSE 12720, the HMF content should be not exceed 50 mg/kg. However, the HMF values of the samples were detected above the maximum limit value except for N8 and N16.
UV and UV+ Water Effects on Mechanical, Thermal and Morphological Properties of Thermoplastic Polyurethane Based Composites
Authors: ŞİŞMANOĞLU Sedef
Published: June 2023

The degradation times of composite materials containing petroleum-based polymer matrix are quite long in nature and it causes environmental pollution. Researchers focus on producing alternative composite materials with organic and/or inorganic fillers to reduce degradation times in nature. In addition, the mechanical and chemical properties of polymer matrix composites are affected by heat, light, moisture and surface compatibility between matrix and filler. In the light of this information, many researchers examine the mechanical, thermal, morphological and similar properties of organic and/or inorganic filler composites by using artificial aging processes using one or more of the water, UV and temperature parameters.
In this study, bentonite with surface modification by epoxysilane agent, and bentonite without any surface modification will be added to the thermoplastic polyurethane (TPU) polymer matrix, which has two different segments, and will be mixed in a twin screw extruder and it will then be shaped by the injection molding process. Artificial aging processes of the obtained composites will be done under UV and UV+water for 2 and 4 weeks, respectively. The reason for choosing UV and UV+water processes is that UV and water processes have not been applied together at the same time and there is not much knowledge in the literature on this subject. Mechanical, thermal and morphological properties of composites were investigated.

Published: June 2023

The Urofacial Syndrome or Ochoa is a very rare clinical condition, and is unknown by a large part of the medical community; it is characterized by an inverted facial expression, resulting from abnormal contraction of facial and ocular muscles, especially when smiling, in addition to the presence of urinary abnormalities. Patients with this syndrome are at a higher risk of developing urinary incontinence, changes in the bladder, vesicoureteral reflux, hydroureteronephrosis, and predisposition to severe urinary infections, in addition to chronic kidney disease. This article presents a case of a 22-year-old female, resident of Piauí/Brazil, who presented at the age of 5, the first symptoms of the disease mainly related to the urinary tract (such as urinary frequency), in addition to the sign of inverted face, in which the patient presents the inverted smile characteristic of the disease when commanded to smile, associated with nocturnal lagophthalmos. The patient evolved at 12 years of age, with end-stage chronic kidney disease and a need for renal replacement therapy. This is one of the rare cases of the disease, in which the patient presents the complete characteristics of the inverted smile pathology and complications in the urinary tract. The inverted facial expression is an easily recognized sign, and it is a very characteristic finding of the disease, not finding explanations of morphological alterations or lesions. therefore, it is evident that early diagnosis with the institution of appropriate treatment, avoids possible damage to the urinary tract from childhood, allowing better management and quality of life in these patients.

Objetivo: Este trabalho tem como objetivo analisar a qualidade das notas explicativas acerca da implementação da IFRS 15 no Brasil.

Método: Foram analisadas 429 empresas do mercado brasileiro, comparando as notas explicativas relacionadas ao efeito da IFRS 15. Houve uma classificação desses efeitos quanto aos impactos registrados em notas explicativas, ou falta deles, no ano de 2017 e comparativamente, em 2018, se esses foram maiores ou menores que os estimados ou ainda, se não foram relatados. Também foi construído um índice para medir a Qualidade das Notas Explicativas (IQNE).

Resultados: Verificou-se que mais da metade das empresas apenas reclassificaram contas para melhor apresentação, aumentaram a divulgação em notas ou não tiveram nenhum impacto. Constatou-se, portanto, que a nova norma não trouxe mudanças significativas que causassem tanto impacto, mas ainda assim viabilizou uma maior utilidade e relevância nas informações financeiras prestadas pelas empresas a seus credores e investidores, principalmente em setores como utilidade pública, comunicação e construção civil.

Contribuições: É relevante ao discutir como as empresas lidam com a adoção de uma nova norma no que tange à sua preparação prévia e à análise dos efeitos efetivamente ocorridos. Também contribui para o Post-Implementation Review (PIR) da IFRS 15.

Published: June 2023

Background: Diabetes mellitus (DM) is a chronic metabolic disorder that can lead to multiple long-term complications in the human body including erectile dysfunction (ED). ED is a condition that commonly affects men and may reduce their quality of life. However, ED amongst men with type 2 DM (T2DM) has rarely been assessed and addressed by nurses who have an essential role in providing holistic patient care.Objective: This study aimed to describe ED among men with T2DM based on their demographic characteristics and health profiles.Methods: This was a descriptive study with a cross-sectional approach of 32 male respondents who were selected through convenience sampling in the outpatient department of PKU Muhammadiyah Hospital Yogyakarta, Indonesia. The data was collected by using the erectile function’s domain of Indonesian version of International Index of Erectile Function (IIEF). Descriptive statistics were used to present this study’s findings.Results: The results showed that  62.5% of the participants had uncontrolled blood glucose levels with an average random blood glucose of 207.75 ± 77.21 mg/dl. Only four respondents (12.5%) had received sexual counselling. Twenty-nine respondents (90,6%) had ED which were categorized into mild (17.2%), mild to moderate (6.9%), moderate (24.1%) and severe (51.7%).Conclusion: ED levels varied across age, duration of T2DM, random blood glucose levels, previous history of smoking, current smoking status, sexual counselling experience, complications, and occupation levels. Severe ED was common amongst men with T2DM in this study. Nurses should assess patient’s sexual function regularly and identify the effects of ED in men with T2DM. Early detection of ED could allow nurses to plan adequate intervention and health education to provide better outcomes for men with T2DM.

Authors: Beltran Serrano Erik , Campos González Israel David
Published: June 2023

Several modalities of renal replacement therapy (RRT) are available for the treatment of end-stage renal disease (ESRD). Patients are likely to face complex medical decisions regarding the type of medical therapy they wish to pursue. A prospective, observational, descriptive and cross-sectional survey case series study was carried out in patients with grade 3-5 chronic kidney disease at the General Hospital ‘Dr. Miguel Silva’ without starting renal replacement therapy. We used descriptive statistics to evaluate the frequency of the categorical variables and measures of central tendency and dispersion for the quantitative variables. The total number of patients included was 20, with a mean age of 54.40±15.93 years and an age range between 24 and 78 years; 55% of the patients evaluated obtained a ‘good’ level of knowledge regarding the types of RRT (HD, PD and renal transplantation). All patients received pre-dialysis information before starting the survey. PD was the preferred RRT modality (45%), followed by kidney transplantation (35%) and finally HD (20%). The patient's level of knowledge regarding his chronic kidney disease allows him to make an informed decision about the choice of the ideal treatment. The most preferred renal replacement therapy for previously educated chronic kidney disease patients is peritoneal dialysis. The distance from the hemodialysis center to your home and work activity are important factors in choosing the type of RRT.

Authors: Kohli Saksham , Agrohi Jhalak , G. K. Adarsha , Agrohi Daksh
Published: June 2023

Empyema necessitans (EN) is a rare long-term sequela of poorly or untreated empyema thoracis, characterized by the dissection of pus through the soft tissues and skin of the chest wall, ultimately forming a fistula between skin and pleural cavity. We herein present a male patient in his late 30s, a known case of tuberculosis (TB) on anti-tubercular therapy (ATT) under directly observed treatment short-course (DOTS), who recently came with complaints of backache for 3 days. Chest X-ray showed a massive pleural effusion, in view of which an intercostal drainage tube (ICD) was inserted and 1.5 L of pleural fluid was drained. An ultrasound (USG) back done revealed subcutaneous collection with communication to pleural space, which resolved after pleural fluid drainage. As there was a persistent communication between pleural space and right-sided subcutaneous plane with a massive effusion i.e., EN, he was advised to undergo thoracotomy with decortication and resection of communication which he underwent successfully. This case is presented for its rarity with atypical presentation.

Published: June 2023

Background: Diabetic foot ulcer (DFU) is a dreaded complication holding huge health and socio-economic impacts and negative impacts on quality of life of individual, community and society as a whole yet carrying scope of preventive potential. The objectives were to find out the prevalence of diabetic foot ulcers and to assess gap in knowledge, foot care practices and their determinants.
Methods: A cross-sectional study was conducted over three months among 310 diabetic outpatients of a medical college of an eastern Indian state. Data were collected with a validated questionnaire containing socio-demographics, clinical and behavioral factors, foot care knowledge and practice and SINBAD score was used for assessing diabetic ulcers.
Results: Out of 310 participants, 44 (14.2%) had diabetic foot ulcer and 1/5th of them had SINBAD score ≥3 indicating severity. Knowledge level was poor among 245 (79.0%) and healthy foot habits were among only 70 (22.6%). Addiction, diabetes for ≥5 years, any associated non-communicable diseases, irregular treatment and follow-up care, unhealthy foot condition, improper foot wear, poor knowledge of the disease and unhealthy foot habits had significant association with occurrence of foot ulcers.
Conclusions: Generation of awareness can bring about prevention of development of foot ulceration among diabetic patients and henceforth can avert risk of adverse consequences of it.
Intraarticular versus intravenous tranexemic acid in reducing blood loss after primary total knee arthroplasty
Authors: Gorkhali Rajendra , Humagain Vaskar , C. Dirgha Raj R. , Marhattha Suman Babu , Bista Rishi
Published: June 2023

Background: One of the substantial complications of total knee arthroplasty is major blood loss. Postoperative blood loss can range up to 2000 ml and 10-38% of patients may require blood transfusion. Among the sundry methods of preventing this prob, tranexamic acid, an anti-fibrinolytic, is one of the most effective options. It can be administered directly into the blood or injected locally. The purpose of this study was to compare the hemostatic effects of intraarticular versus intravenous administration of tranexamic acid in primary total knee arthroplasty.
Methods: A prospective comparative observational study was done from done September 2020 to February 2022 at Civil Service Hospital, Kathmandu. 64 patients randomized into two groups: an intraarticular tranexamic acid group (31 patients who received 3.0 grams of intraarticular tranexamic acid) and intravenous tranexamic acid group (31 patients who received 15 mg/kg intravenous tranexamic acid in two instances). The primary measure was the amount of hemoglobin loss. Secondary outcomes included comparison of hemoglobin level pre- and post- operatively at first and fifth day, drain volume at 48 hours and amount of blood transfusion. There were no significant differences in demographics or preoperative laboratory values between the groups.
Results: The baseline data, preoperative hemoglobin, and tourniquet time were similar in both groups. Hemoglobin at first and fifth operative day and drain volume at 48 hours were measured in both categories. There was no significant difference in perioperative blood loss, drain volume, rates of allogeneic blood transfusion between the two groups.  No any thromboembolic complications occurred.
Conclusions: Intra-articular administration of tranexamic acid was found to be as effective and safe as intra-venous administration in reducing blood loss in primary total knee arthroplasty.

Controlled vibration protection systems: optimization and energy efficiency
Authors: Chernyshev V. I. , Polyakov R. N. , Fominova O. V.
Published: June 2023

The energy efficiency of controlled vibration protection systems is defined as the ratio of the vibration safety indicator they achieve to the cost of energy resources necessary to achieve the desired indicator. To solve the optimization problems of controlled vibration protection, a sufficient condition for the optimality of the accepted functional and, accordingly, the minimum principle, was used, the step-by-step implementation of which, in the course of numerical integration of the initial equations of the state of the system, makes it possible to reproduce the optimal control numeric arrays and the related components of the system state. The algorithm of the step-by-step procedure of the minimum principle was used to optimize the dynamic processes in the vibration protection system with indirect control of the viscous resistance damper and the potential energy recuperator. It has been established that the optimal controls that allow eliminating resonant phenomena in these systems are positional functions of a singular type, the relay switching of which in vibration protection systems with a controlled damper and recuperator is associated with a change in the sign of the absolute and relative velocity of the object and with a change in the sign of the velocity and relative displacement of the object.
Effect of Endurance Training on Long-Term Stroke Survivors
Authors: Kanase Suraj
Published: June 2023

Background: Stroke is one of the leading causes of dependency and mortality in India. Chronic stroke is defined as 6 months to years from the time of onset. Structural impairment which occurs in stroke lead to the complex nature of functional limitations. High blood pressure, diabetes mellitus, blood vessel diseases, and obesity are a few risk factors that can cause stroke. Once the patient goes into the chronic phase, a wide range of problems in functional mobility, gait, and Quality of Life may occur. Majority of times the patient survives their remaining life with these disabilities. The survival rate decreases with an increase in time. Only 1% survive 20 years after stroke. Physiotherapy has shown a positive effect on functional outcomes in acute stroke. Its efficacy should be tried on chronic survivors. Method: 36 subjects were included as per the inclusion and exclusion criteria. The treatment protocol was given for 42 days. Pre and post-changes in subjects were analyzed on a modified Barthel index and stroke-specific Quality of Life scale. Result: Data was analyzed using the student’s t-test. Findings showed significant change in outcome measures interns of mobility and quality. Conclusion: Endurance training improves functional mobility and standard of living in chronic stroke survivors.

The research about automatic text summarization is common in English text. According to the previous study, automatic text summarization in Bahasa Indonesia is still challenging due to research in this area, especially the research which discusses TextRank algorithm performance, which is still meagerly. Accordingly, this research observes the performance of the TextRank algorithm to summarize the text in Bahasa Indonesia. The TextRank algorithm summarizes a text by sorting out the essential words and relevant sentences regardless of the source language. This algorithm uses a vertex to represent a word. The similarity measurement process will calculate the overlapping words (the same word between two vertices). These overlapping words are represented by the edge, which connects the vertices. Thus, the text forms a graph. This research focuses on the similarity measurement process to determine relevant sentences in a text. As the similarity measurement is critical for the summarization result, this research switches the original process to the Levenshtein Distance algorithm and observes its performance. This research uses the human-produced summarized text by the expert in Bahasa Indonesia linguistics to evaluate the result. The evaluation method is conducted by using ROUGE-1 and ROUGE-2. The result shows that the average of ROUGE-1 and ROUGE-2 for the TextRank algorithm is 0.439 and 0.3186, respectively. Meanwhile, the modified TextRank obtains 0.3999 and 0.2805, respectively. Both of the algorithms have not shown satisfactory results as expected.

Infections frequently develop because catheter insertion is a case of HAIs (Health Care Associated Infections) that occur as a result of non-compliant procedures and activities by healthcare providers. This research approach is a pre-post design model experiment. The sample was divided into two groups: the treatment group and the control group. Each consists of 20 respondents. An independent sample t-test was used to analyze the data to determine the impact of UTI prevention and control bundles on CAUTI in inpatients. The results showed that no bacterial growth was found in the control group who underwent urine culture examination at the beginning of the catheterization (pre-test), but bacterial growth was discovered after 72 hours (post-test), with candida albicans > 105 CFU/ml found by four respondents (20%), staphylococcus aureus 105 CFU/ml found by one respondent (5%), and Escherichia coli >105 CFU/ml found by one respondent (5%). During the pre-test and post-test, no evidence of bacterial growth was discovered in the treatment group. The findings of the independent sample t-test revealed that the prevention and control of UTI prevention and control bundles had a significant effect on CAUTI in inpatients, with a value of p = 0.000 (p

Stroke is one of the main problems in the medical field, one of the top 3 causes of death in the world. 1) Coronary heart as much as 13%, 2) Cancer as much as 12%, 3) Stroke as much as 7.9%. Stroke often occurs in developing countries, such as Indonesia. One effort to minimize the risk of stroke is to take preventive measures in stroke patients, both before and after a stroke. The way to prevent stroke is by primary and secondary measures. Prevention of stroke symptoms can be avoided with fast and appropriate treatment in stroke care according to medical service standards. This study applies texture analysis and improves the quality of CT-Scan or Magnetic Resonance Imaging (MRI) brain images using the Hybrid Thresholding (HT) method, which is a combination of edge detection methods and P-Files. Differences in the texture of images of brain hemorrhages that indicate stroke and clarify the quality of images of brain hemorrhages that indicate strokes with the parameters of contrast, correlation, energy, and homogeneity. The results of segmentation and feature extraction and texture are then classified using the Backprogation Neural Network (BNN) method with variations in learning rate values. This study produces the best test at a learning rate of 0.1 with an error percentage of 2%. The results of the classification calculation of the area of brain hemorrhage and analysis of image quality in classifying stroke brain with an accuracy level of 27/3 x 100% = 90%.

Retrieving images that are similar to the query image in the image database means determining the similarity between the images. This study aims to use a graph method with region adjacency graph representation in conjunction with a non-graph method in image retrieval. We represented an image as a graph and used the Graph Edit Distance (GED) method to calculate the similarity between two graphs. The feature extraction of the image graph, which exposes the content and the relationships between existing content, is a key step in image retrieval based on the graph method. The extraction of graph features is accomplished by the image segmentation method, which divides the image into regions and represents them as a region-adjacency graph (RAG), in which vertices represent regions and edges indicate two neighboring regions. Image retrieval based on the graph method is combined with low-level approaches like Color Moments, Gray Level Co-occurrence Matrix (GLCM), and Hu Moments to boost accuracy. All obtained features are normalized, weighted, and then compared between images to get the similarity value using Euclidean Distance. An image retrieval prototype based on the combined graph method and non-graph method was successfully created in this work, using four datasets: synthetic, batik, COIL-100, and Wang. The MAP of the four datasets is 67.84 percent, but when combined with the low-level feature approach, it rises to between 79.73 and 89.71 percent. The combination of graph and non-graph algorithms improves image retrieval outcomes.
