Authors: Sun Jihang , Yang Lixin , Zhou Zuofu , Zhang Dan , Han Wei , Zhang Qifeng , Peng Yun
Published: June 2019

Background
The adverse effect of low-dose CT on image quality may be mitigated using iterative reconstructions. The purpose of this study was to evaluate the performance of the full model-based iterative reconstruction (MBIR) and adaptive statistical reconstruction (ASIR) algorithms in low radiation dose and low contrast dose abdominal contrast-enhanced CT (CECT) in children.

Methods
A total of 59 children (32 males and 27 females) undergoing low radiation dose (100kVp) and low contrast dose (270 mgI/ml) abdominal CECT were enrolled. The median age was 4.0 years (ranging from 0.3 to 13 years). The raw data were reconstructed with MBIR, ASIR and filtered back projection (FBP) algorithms into 6 groups (MBIR, 100%ASIR, 80%ASIR, 60%ASIR, 40%ASIR and FBP). The CT numbers, standard deviations, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of liver, pancreas, kidney and abdominal aorta were measured. Two radiologists independently evaluated the subjective image quality including the overall image noise and structure display ability on a 4-point scale with 3 being clinically acceptable. The measurements among the reconstruction groups were compared using one-way ANOVA.

Results
The overall image noise score and display ability were 4.00±0.00 and 4.00±0.00 with MBIR, and 3.27±0.33 and 3.25±0.43 with ASIR100%, respectively, which met the diagnostic requirement; other reconstructions couldn’t meet the diagnostic requirements. Compared with FBP images, the noise of MBIR images was reduced by 62.86%-65.73% for the respective organs (F=48.15-80.47, P<0.05), and CNR increased by 151.38%-170.69% (F=22.94-38.02, P<0.05).

Conclusions
MBIR or ASIR100% improves the image quality of low radiation dose and contrast dose abdominal CT in children to meet the diagnostic requirements, and MBIR has the best performance.

Background

Systemic Inflammatory Response Syndrome (SIRS) criteria are often used to evaluate the risk of sepsis and to identify in-hospital mortality among patients with suspected infection. However, utilization of the SIRS criteria in mortality prediction among geriatric patients with influenza in the emergency department (ED) remains unclear. Therefore, we conducted a research to delineate this issue.

Methods

This is a retrospective case–control study including geriatric patients (age ≥ 65 years) with influenza, who presented to the ED of a medical center between January 1, 2010 and December 31, 2015. Vital signs, past history, subtype of influenza, demographic data, and outcomes were collected from all patients and analyzed. We calculated the accuracy for predicting 30-days mortality using the SIRS criteria. We also performed covariate adjustment of the area under the receiver operating characteristic curve (AUROC) via regression modeling.

Results

We recruited a total of 409 geriatric patients in the ED, with mean age 79.5 years and an equal sex ratio. The mean SIRS criteria score was 1.9±1.1. The result of a Hosmer–Lemeshow goodness-of-fit test was 0.34 for SIRS criteria. SIRS criteria score ≥ 3 showed better mortality prediction, with odds ratio (OR) 3.37 (95% confidence interval (CI), 1.05–10.73); SIRS score ≥ 2 showed no statistical significance, with p = 0.85 (OR, 1.15; 95% CI, 0.28–4.69). SIRS score ≥ 3 had acceptable 30-days mortality discrimination, with AUROC 0.77 (95% CI, 0.68–0.87) after adjustment. SIRS score ≥ 3 also had a notable negative predictive value of 0.97 (95% CI, 0.94–0.99).

Conclusion

The presence of a higher number of SIRS criteria (≥ 3) showed greater accuracy for predicting mortality among geriatric patients with influenza.

Published: June 2019

Popülizm, geçmişten günümüze
farklı ülkelerde farklı siyasal rejimlerde zaman zaman ortaya çıkabilmiştir. Bu
nedenle bu farklı örneklerin genel özellikleri üzerinden popülizm tanımlanmaya
çalışılır. Buna göre popülizmin en belirgin özelliği halkçı söylemlere dayanan
bir ideolojik yaklaşım olmasıdır. Popülizmde sıklıkla halk iradesine vurgu yapılır. Popülizmde halk
iradesinin gerçek temsili savunulur, bu amaçla doğrudan demokrasi çağrıları
yapılır. Hemen her siyasal rejim tipinde ortaya çıkabilen popülizm gerçekte bir
popülist seçkinler hakimiyetini ortaya çıkarır. Çoğu yazar tarafından popülizm
bir ideoloji, politik görünüş ya da siyasi hareket tarzı olarak olumsuz
yorumlanabilmektedir. Kimi yazarlara göre ise popülizm, temsili demokraside ya
da halkın temsilinde eleştirilebilecek noktalar olduğunu hatırlatmaktadır. Bu
noktadan hareketle popülizmin olumlu yanlarına da odaklanılmalıdır. Sıradan
insanın daha güçlü temsilini savunan popülizmin siyasal katılımı artırdığı
söylenebilir. Bu yönüyle demokrasiye katkı sunmaktadır. Çalışmada özellikle
üzerinde durulan nokta popülizmin demokrasiye ve temel hak ve özgürlüklere
tehdit oluşturup oluşturmadığıdır. Popülizm benzer inanç ve düşünceleri taşıyan
insanları bir araya getirerek tekliği ortaya çıkarmaktadır. Buradan hareketle
farklılıkların temsiline olanak veren çoğulcu demokratik anlayışı tehdit edip
etmediği tartışılması gerekli bir konu haline gelmektedir. Bu çerçevede
popülizmin çoğunlukçu demokrasiyle aynı anlama geldiği söylenememekle birlikte
temsili ve çoğulcu demokrasiyi, çoğunlukçu demokrasiye doğru yönlendirdiğine
değinilebilir. Popülist bir hareketin ortaya çıkabilmesi belirli koşullar
gerektirmese de demokrasi var olduğu sürece popülizmin de var olacağı iddia
edilebilir. Zira popülizm halkın temsiliyle ilgilidir. Bu nedenle denilebilir
ki popülizm güncelliğini yitirmeyen bir kavramdır. Çalışmada konunun seçiminde
popülizmin sınır ve zaman tanımayan bir kavram olması etkili olmuştur. Popülizm

Application of water supply operation system to improve efficiency of hydraulic power generation
Authors: Tanaka T. , Kaneko S. , Aoyama N. , Toriyama Y.
Published: June 2019

At various locations in Tokyo, the excess pressure of water entering the water supply distribution reservoirs is adjusted by pressure reducing valves, wasting unused energy. The installation of hydraulic power generation equipment is now promoted in place of the pressure reducing valves. This is a renewable energy source as the method produces no greenhouse gases and reduces fossil fuel use. The results of research into the operation of the hydraulic power generation equipment enable the water supply operating system to optimize the inflow rate for power generation without affecting the stability of the water supply. This has increased the amount of power generated and enabled earlier recovery of total costs.

Authors: Kharazmi Parastou
Published: June 2019

Water and wastewater pipes require some of the highest levels of infrastructure investment; they also deteriorate faster than they can be repaired. The use of alternative rehabilitation technologies, which are quicker and less expensive than pipe replacement, has therefore increased significantly in recent years, worldwide. Field studies on relined wastewater pipes removed from buildings in different parts of Sweden revealed the existence of a variety of common defects, most of which could have been prevented by better installation. Increased quality-focused monitoring could help to ensure that relined pipes reach their expected service life, while comprehensive documentation could assist in providing sufficient information to facilitate progress in the field. This paper includes a brief overview of the technologies used in Sweden, current quality control practices, repeated observed defects related to installation, crucial steps that affect final quality, and recommendations to be considered in the contexts of detailed quality control and quality assurance procedures.

Authors: Michelon William , Pirolli Mateus , Mezzari Melissa Paola , Soares Hugo Moreira , da Silva Márcio Luís Busi
Published: June 2019

The present study assessed the carbohydrate and sugar production from Chlorella spp. biomass harvested from a field scale reactor simulating phycoremediation of swine wastewater. The microalgae biomass was mainly composed by (%): carbohydrates (41 ± 0.4), proteins (50 ± 0.4), and lipids (1.3 ± 0.5). The residual sugar present in the biomass was extracted via acid hydrolysis. Among different concentrations of sulfuric acid tested (i.e., 47, 94, 188, 281 and 563 mM), significantly higher sugar content was obtained with 188 mM (0.496 g-sugar g−1 microalgae-DW). The concentration of sugar present in the microalgae did not differ significantly between the biomasses harvested by either centrifugation or coagulation-flocculation. Two commercially available strains of yeast (i.e., Saccharomyces cerevisiae and S. cerevisiae chardonnay) were tested for their capability to ferment sugar from lyophilized microalgae biomass. S. cerevisiae chardonnay showed a significantly faster consumption of sugar during the exponential growth phase. Both strains of yeast were capable of consuming most of the sugar added ≅ 8 g L−1 within 24 h. Overall, the results suggest that carbohydrate-rich microalgae biomass obtained from the phycoremediation of swine wastewaters can play an important role in green design for industries seeking alternative sources of feedstock rich in sugar.

Appearing not long ago, new psychoactive substances (designer drugs), including synthetic cannabinoids, derivatives of cathinone, phenethylamines, new stimulants, synthetic opioids, tryptamine derivatives, phencyclidine, piperazine, the GABA (A/B) receptors agonists, have become a serious problem for consumers and for physicians. Consumers of these substances are attracted primarily by the intensity of psychoactive effects, and the «legal high» declared by the black manufacturers, which indicates that significant difficulties in a laboratory identification of new surfactants. Designer drugs, when ingested, can be influenced on many neurotransmitter pathways/receptors: dopamine, cannabinoid (CB1), GABA (A/B), 5-HT2A, glutamate, and k-opioid receptors (KOR), the imbalance of which leads to the development of polymorphic psychotic disorders.

The role of impulsivity and impulse control disorders in the formation of addictive disorders
Authors: Dubatova Irina Vladimirovna , Antsyborov Andrey Viktorovich
Published: June 2019

Currently, a lot of researches devoted to the study of the relationship between disorders of impulse control and addictive pathology are published. Attempts to isolate behavioral addictions into a separate group of addictive disorders make it necessary to assess impulsivity and impulse control disorders at different stages of formation, both behavioral and substance use addictions in a new way. This review is based on the results of research and analysis of existing models of addictive disorders, where the dominant position is given to impulsivity and impulse control disorders as predictors of addictive pathology. It contributes to most forms of aberrant management and other disorders included in the current classifications (DSM-V, ICD-10). In our opinion, many existing models of addictive pathology of impulsivity and impulse control disorders is given undeservedly little attention, which in the end leads to an incorrect assessment of substance and behavioral addictions. A model of development of addictive disorders is proposed, where the disorder of impulse control is given a decisive place in the question of «to be or not to be» addictive pathology.

Metabolic Cage for Urine Collection from Small Animals with High Level of Performance and Low Cost
Authors: Tokaruk Nadiya
Published: June 2019

The results of designing the original metabolic cage for urine collection from small laboratory animals consisting of a case, a cylindrical animal chamber with the floor, a funnel, a urine collection vessel and two graded drinking bottles that can be placed at a different height depending on animal age are presented. The case was made of laminated particle board; a cylindrical animal chamber was made of polyethylene terephthalate; a circular floor of the animal chamber was made of stainless steel wire cloth mesh. As a funnel for urine collection, a ribbed glass funnel SIMAX (Czech Republic) was used. To prevent rat feces from entering the urine collection vessel, there were installed two stainless steel wire mesh filter discs, namely a larger disc located on the internal ribbed surface of the funnel and a smaller disc located close to the hole of the funnel tube. To support the urine collection vessel, a metal vessel stand with a deepening was made. Between the vessel and the funnel, there was placed a fine stainless steel metal cylinder preventing urine evaporation.

In addition to low cost, the proposed design of the metabolic cage provides high levels of performance as confirmed by its high ability to allow urine to flow freely, as well as to collect urine, significantly smaller volume of urine evaporated, improved housing conditions for animals and allows us to collect the amount of urine more fully reflecting animal diuresis.

Authors: Serediuk Lesia , Vakalyuk Ihor , Kerniakevych Halyna
Published: June 2019

The objective is to investigate the influence of stress on the clinical and pathogenetic peculiarities of the course of stable coronary heart disease (SIHD) in conjunction with atrial fibrillation (AF).

Materials and methods. The analysis of psychodiagnostic tests, labolatory and instrumental research methods in patients with and without AF has been performed. Patients were divided into three groups: group 1 – patients with stable ischemic heart disease (SIHD) with a constant form of AF (15 patients were examined), group 2 – patients with SIHD with paroxysmal form of AF (16 patients were examined), group 3 – patients with SIHD without AF (15 patients were examined).

Results. According to the analysis of the data obtained, low level of stress was found in 6 (37.50%) patients with a permanent form of AF, whereas in patients without AF, it was observed in 1 (6.67%) person (p1<0.05) (p1 – the reliability of the differences in indicators relative to patients without AF). Moderate somatic disorder in women with paroxysmal AF was significantly higher than in the group of patients with a constant form of AF (p2<0.05) (p2 – the reliability of the differences in the indicators relative to patients with a constant form of AF). It is confirmed in patients with AF there are signs of the average stress level on the perceived stress level-10 (p2<0.05). Among the social factors that may have an impact on health are the influence of the media, the use of alcohol by relatives, the threat of unemployment for relatives and friends. These indicators were most often found in the group of patients with AF rather than without it (p2<0.05). Changes of ECG and echocardiographic parameters in all groups of patients were revealed.

Conclusion. The association of stress with stable ischemic heart disease combined with atrial fibrillation has shown that stress disorders are associated with an increased risk of atrial fibrillation and may worsen their course and predict the risk of developing paroxysm. The dependence between the severity of clinical manifestations, psychodiagnostic tests, laboratory methods, ECG and echocardiographic parameters of the heart on the course of atrial fibrillation is proved.

Published: June 2019

Pollution of the environment with heavy metals, pesticides, nitrates leads to an unceasing deterioration of the population’s health, in particular, the dental one. Excessive intake of salts of heavy metals and nitrites is accompanied by changes in calcium-phosphorus metabolism rates, indicating a disorder of metabolic processes in bone tissue. This necessitates the study of the level of osteotropic elements of the jaw bone tissue.

Materials and methods of research. In the experiment on 80 white outbred male rats, the effects of cadmium chloride, sodium nitrite and their combined action on the content of osteotropic elements in the jaw bone were studied. The control group consisted of 10 intact animals.

Results. It was determined that in the dynamics (1st, 14th, 28th days) of both cadmium-nitrite, nitrite and cadmium intoxication there was observed the accumulation of cadmium and decrease of calcium, copper, zinc levels in bone tissue of animal jaws compared to intact group.

Conclusions.The most significant changes in the level of osteotropic elements in the jaw bones are found in the combined effect of xenobiotics, which is important for understanding of the metabolic processes in the oral cavity.

Published: June 2019

Pellet gun used by law enforcement agencies have the potential to cause grevious or life threatening injuries as metallic projectiles fired at high speeds from pellet gun have potential to damage air containing organs like lungs which occupy a large portion of chest cavity and lie in close approximation to chest wall. Thoracic injury overall is the third most common cause of trauma following injury to the head and extremities.

Objective. The objective of this study was to evaluate lung pellet gun injuries in patients of a conflict zone by a so called non-lethal weapon.

Methods. The study was conducted in post graduate department of Radiodiagnosis and Imaging, Government Medical College, Srinagar Jammu and Kashmir. Our study was performed between the 6th January 2019 to the 22th May 2019. A total of 40 patients with pellet injuries were taken up for study.

Inclusion criteria were patients with pellet gun injuries without any immediate life threatening injury like head injury; patients willing to be part of study. Radiographs of all the patients were studied.  Whenever there was suspicion of severe injury, CT scan was done. We obtained thin-section axial CT scans (0.625– 1.25 mm) with multiplanar reformation with an interval of 3-5 mm.

Results. All of the patients were males with most of patients in age group of 20 to 30 years.

About 14 patients out of 40 had lung injuries. The most common pattern of lung injury was pneumothorax followed by pulmonary hemorrhage.

In conclusion, a so called non-lethal pellet gun used by law enforcement agencies has the potential to cause lung injuries which can sometimes be lethal to life especially when  fired from short distance.

Authors: Kupnovytska Iryna , Romanyshyn Nelia
Published: June 2019

The objective of the research was to study myocardial hemodynamics and contractility, as well as N-terminal pro-brain natriuretic peptide secretion in the patients with chronic coronary artery disease depending on affected coronary artery number according to coronary angiography.

         Materials and methods. The study included 62 patients with chronic coronary artery disease, heart failure with preserved left ventricular ejection fraction. Among the examined patients, males prevailed – 52 (83.9%) individuals. The average age was 61.2±1.2 years. The control group included 15 apparently healthy individuals with preserved gender and age proportions. The patients were randomized by the number of the affected coronary arteries and divided into 2 subgroups according to the results of coronary angiography. Subgroup I included 16 (25.8%) patients with single-vessel coronary artery disease; subgroup II comprised 46 (74.2%) patients with multivessel coronary artery disease.

          Results and discussion. According to Holter monitoring, average and maximum heart rate, extrasystoles and episodes of ST-segment depression/elevation were more often found in the patients with multivessel coronary artery disease (p<0.05). According to echocardioscopy, in the patients with coronary artery disease regardless of affected coronary artery number, hemodynamic indicators were higher as compared to healthy individuals (p<0.001), while left ventricular ejection fraction was lower in the patients with multivessel coronary artery disease (р<0.001). Serum level of N-terminal pro-brain natriuretic peptide exceeded reference value in both single-vessel coronary artery disease and multivessel coronary artery disease (р<0.001); however, the secretion of this peptide increased in multivessel coronary artery disease (р<0.05). There was observed a strong inverse correlation between left ventricular ejection fraction and N-terminal pro-brain natriuretic peptide in the patients with multivessel coronary artery disease and a moderate correlation in the patients with single-vessel coronary artery disease.

         Conclusions. The nature and severity of coronary artery disease clinical course are associated with the number of the coronary arteries affected by atherosclerotic plaques. In multivessel coronary artery disease, according to the results of clinical, functional and laboratory studies, there was observed persistent progression of coronary artery disease and, consequently, chronic heart failure that is the reason for the improvement of schemata for successful treatment of the disease.

Why Do Data Users Say Health Care Data Are Difficult to Use? A Cross-Sectional Survey Study
Authors: Kim Ho Heon , Kim Bora , Joo Segyeong , Shin Soo-Yong , Cha Hyo Soung , Park Yu Rang
Published: June 2019

Background

There has been significant effort in attempting to use health care data. However, laws that protect patients’ privacy have restricted data use because health care data contain sensitive information. Thus, discussions on privacy laws now focus on the active use of health care data beyond protection. However, current literature does not clarify the obstacles that make data usage and deidentification processes difficult or elaborate on users’ needs for data linking from practical perspectives.

Objective

The objective of this study is to investigate (1) the current status of data use in each medical area, (2) institutional efforts and difficulties in deidentification processes, and (3) users’ data linking needs.

Methods

We conducted a cross-sectional online survey. To recruit people who have used health care data, we publicized the promotion campaign and sent official documents to an academic society encouraging participation in the online survey.

Results

In total, 128 participants responded to the online survey; 10 participants were excluded for either inconsistent responses or lack of demand for health care data. Finally, 118 participants’ responses were analyzed. The majority of participants worked in general hospitals or universities (62/118, 52.5% and 51/118, 43.2%, respectively, multiple-choice answers). More than half of participants responded that they have a need for clinical data (82/118, 69.5%) and public data (76/118, 64.4%). Furthermore, 85.6% (101/118) of respondents conducted deidentification measures when using data, and they considered rigid social culture as an obstacle for deidentification (28/101, 27.7%). In addition, they required data linking (98/118, 83.1%), and they noted deregulation and data standardization to allow access to health care data linking (33/98, 33.7% and 38/98, 38.8%, respectively). There were no significant differences in the proportion of responded data needs and linking in groups that used health care data for either public purposes or commercial purposes.

Conclusions

This study provides a cross-sectional view from a practical, user-oriented perspective on the kinds of data users want to utilize, efforts and difficulties in deidentification processes, and the needs for data linking. Most users want to use clinical and public data, and most participants conduct deidentification processes and express a desire to conduct data linking. Our study confirmed that they noted regulation as a primary obstacle whether their purpose is commercial or public. A legal system based on both data utilization and data protection needs is required.

La gloria eres tú y la Revolución sandinista
Authors: Pacheco-Solórzano Carlos Adán
Published: June 2019

La gloria eres tú es una novela histórica del escritor y poeta nicaragüense Manuel Martínez, que recrea con nostalgia el mundo idealizado por la Revolución sandinista. La novela no es un relato de grandes acontecimientos heroicos: es la vida simple de Josué y compañeros de lucha que aman, viven y se desencantan. Para comentar este texto, se parte de tres categorías literarias: héroe o héroes polifónicos, intertextualidad e interdiscursividad, que permitirán desgranar la conciencia del joven guerrillero Josué, que renuncia a su militancia política por los errores del proceso revolucionario. La desilusión del protagonista es simétrica con el proceso revolucionario y también es un llamado a la reflexión para no seguir repitiendo los errores históricos de una utopía que siempre espera ser alcanzada.

Tumors contain a high degree of cellular heterogeneity. Various type of cells infiltrate the organs rapidly due to uncontrollable cell division and the evolution of those cells. The heterogeneous cell type and its quantity in infiltrated organs determine the level maglinancy of the tumor. Therefore, the analysis of those cells through their nuclei is needed for better understanding of tumor and also specify its proper treatment. In this paper, Speeded Up Robust Feature (SURF) is implemented to build a system that can detect the centroid position of nuclei on histopathology image of colon cancer. Feature extraction of each nuclei is also generated by system to classify the nuclei into two types, inflammatory nuclei and non-inflammatory nuclei. There are three classifiers that are used to classify the nuclei as performance comparison, those are k-Nearest Neighbor (k-NN), Random Forest (RF), and State Vector Machine (SVM). Based on the experimental result, the highest F1 score for nuclei detection is 0.722 with Determinant of Hessian (DoH) thresholding = 50 as parameter. For classification of nuclei, Random Forest classifier produces F1 score of 0.527, it is the highest score as compared to the other classifier.

Published: June 2019

In this paper, a controller has been presented by the root locus method based on the state space average model of the boost switching regulator with all of the converterâ€™s parameters and uncertainties. In this model, the load current is unknown and the inductor, capacitor, diode and active switch are non ideal and have an on-state resistance. Furthermore, an on-state voltage drop has been considered for diode and active switch. By neglecting the load current and assuming the ideal elements the simplified model of the regulator has been caddied out. By these complete and simplified models, a step by step method has been proposed to design a single input single output (SISO), second order controller based on roots locus method. In this regard the controller's electronic circuit has been introduced by operational amplifiers. At the end, by simulation of the complete closed-loop system in MATLAB Simulink environment and comparing its results by the results of the regulator and controller circuits in PLECS, the accuracy of the designed controller performance has been shown.

Maintaining the water quality of a pond is one of the main issues on aquaculture management. Water quality represents the condition of a pond based on several water parameters such as dissolved oxygen (DO), temperature, pH, and salinity. All of these parameters need to be strictly supervised since it affects the life-sustainability of cultivated organisms. However, DO is said to be the main parameter since it affects the growth and survival rate of the shrimp. Therefore, a water quality control and monitoring system is needed to maintain water parameters at acceptable value. The system is developed on a mini-PC and microcontroller which are integrated with several sensors and actuator forming an embedded system. Then, this system is used to collect water quality data that is consisting of several water parameters and control the DO as the main parameter. In accordance with the stability needs against the sensitive environment, a fuzzy logic-based controller is developed to maintain the DO rate in the water. This system is also equipped with SIM800 module to notice the farmer by SMS, built-in wifi module for web-based data logging, and improved with Android-based graphical user interface (GUI) to perform user-friendly monitoring. From the experiment results, a fuzzy controller that is attached to the system can control the DO at the acceptable value of 6 ppm. The controller is said to have high robustness since its deviation for long-time use is only 0.12 ppm. Another test shows that the controller is able to overcome the given disturbance and easily adapt when the DOâ€™s set point is changed. Â Finally, the system is able to collect and store the data into cloud storage periodically and show the data on a website.

Published: June 2019

The existing image search system often faces difficulty to find a appropriate retrieved image corresponding to an image query. The difficulty is commonly caused by that the usersâ€™ intention for searching image is different with dominant information of the image collected from feature extraction. In this paper we present a new approach for content-dependent image search system. The system utilizes information of color distribution inside an image and detects a cloud of clustered colors as something - supposed as an object. We applies segmentation of image as content-dependent process before feature extraction in order to identify is there any object or not inside an image. The system extracts 3 features, which are color, shape, and texture features and aggregates these features for similarity measurement between an image query and image database. HSV histogram color is used to extract color feature of image. While the shape feature extraction used Connected Component Labeling (CCL) which is calculated the area value, equivalent diameter, extent, convex hull, solidity, eccentricity, and perimeter of each object. The texture feature extraction used Leung Malik (LM)â€™s approach with 15 kernels.Â  For applicability of our proposed system, we applied the system with benchmark 1000 image SIMPLIcity dataset consisting of 10 categories namely Africans, beaches, buildings historians, buses, dinosaurs, elephants, roses, horses, mountains, and food. The experimental results performed 62% accuracy rate to detect objects by color feature, 71% by texture feature, 60% by shape feature, 72% by combined color-texture feature, 67% by combined color-shape feature, 72 % combined texture-shape features and 73% combined all features.
