IMPLEMENTATION OF PRIVACY PRESERVING AND DYNAMIC SEARCHING MECHANISM WITH BIOMETRIC AUTHENTICATION IN CLOUD STORAGE
Authors: Et. al. Sarita Motghare,
Published: April 2021

In the recent times, cloud storage tends to be a primary storage means for external data. Cloud defense of the data against attacks is the main challenge. Private or semi-private information growth has rapidly expanded over the information network; privacy safeguards have failed to address the search mechanisms. In the field of information networks, privacy protection is an important factor in carrying out various data mining operations with encrypted data stored in different storage systems. A tolerance and protection against data corruption mechanism should be developed which is difficult to achieve. Furthermore, as there is no adequate audit mechanism, the integrity of the stored data become questionable. In addition to this, the user authentication is another challenge. The current solution provides only a remote audit mechanism. It requires data owners to always remain online so that the auditing process is manually handled, which is sometimes unworkable. In this paper, we propose a new, regenerative, public audit methodology accompanied by third-party audits. The existing data search system provides one solution that can be used to maintain the confidentiality of indexing. Documents are stored on a private server in plain word form, which compromise the protection of privacy. So that this system is improved to make the document more secure and efficient, we first store the documents in encrypted form on server, and use the Key Distribution Center (KDC). To generate keys the KDC uses the user's biometric feature. In order to improve the search experience, we also implement TF-IDF, which provides an efficient evaluation of the results. Lastly, we carry out comprehensive data set experiments to evaluate our proposed system performance. Experimental results demonstrate that in terms of safeguarding the privacy, efficient and safe search for encrypted distributed documents the proposed system is better than existing. The methodology suggested also includes an auditing mechanism by third parties to ensure data integrity.
AN INTEGRATED FRAMEWORK FOR SLA-AWARE MULTI-OBJECTIVE TASK SCHEDULING IN CLOUD COMPUTING
Authors: Et. al. Yadaiah Balagoni,
Published: April 2021

Cloud services are offered to consumers based on Service Level Agreements (SLAs) signed between Cloud Service Provider (CSP) and consumer. Due to on-demand provisioning of resources there is exponential growth of cloud consumers. Job scheduling is one of the areas that has attracted researchers to improve performance of cloud management system. Along with the on premise infrastructure, Small and Medium Enterprises (SMEs) also depend on public cloud infrastructure (leading to hybrid cloud) for seamless continuity of their businesses. In this context, ensuring SLAs and effective management of hybrid cloud resources are major challenging issues to be considered. Hence, there is a need for an effective scheduling algorithm which considers multiple objective functions like SLA (deadline), cost and energy while making scheduling decisions. Most of the state of the art schedulers in hybrid cloud environment considered single objective function. However, in real world, it is inadequate for scheduling effectiveness. To overcome this problem, we proposed an integrated framework which ensures SLAs (deadline), cost effectiveness and energy efficiency with an underlying scheduling algorithm known as SCE-TS. This algorithm is evaluated with different workloads and SLAs using a cloud platform. The empirical study revealed that the proposed framework improves scheduling efficiency in terms of meeting SLAs, cost and energy efficiency. It is evaluated and compared with the state of the art and found to be effective in making scheduling decisions in cloud environment.
IMPACT OF THE DIGITAL DIVIDE ON DIGITAL LEARNING IN ASSAM: ECONOMIC CAUSES BEHIND IT.
Authors: Et. al. Salman Hussain,
Published: April 2021

Digital learning is one of the most influential alternatives for mitigating the effects of a pandemic on the teaching-learning process. Especially in the present COVID-19 crisis, digital learning has emerged as a great alternative for continuing academic activities where the physical gathering is completely prohibited. Academic institutions and other online learning platforms take initiatives to promote digital learning process during these days, but the digital divide has stood as the main barrier in the front of it. In this paper, we have found that the digital divide is the main factor responsible for the failure of digital learning in Assam. Though there are different causes of the digital divide existed, we have limited our discussion by focusing explicitly on economic causes of the digital divide in Assam. Illiteracy, lack of skills, inadequate investment in ICT, infrastructural gap, low PCI are the major factors responsible for the digital divide in Assam.
A STUDY ON SOFTWARE DEFECT PREDICTION SYSTEM USING DATA MINING TECHNIQUES
Authors: Et. al. J. Mary Catherine,
Published: April 2021

Defects in software modules are a source of significant concern. Software reliability and software quality assurance ensure the high quality of applications. A software defect triggers software malfunction in an executable product. A number of methods for forecasting machine faults have been suggested, but none have proven to be sufficiently accurate. In the design of software error prediction models, the aim is to use metrics that can be obtained comparatively early in the life cycle of software production to provide fair initial quality estimates of an evolving software framework.Here are various data mining classification and forecasting techniques. Artificial Neural Network (ANN), K-Nearest Neighbor (KNN) have been analyzed and compared for software defect prediction model development. For this paper, the DATATRIEVETM project developed by Digital Engineering, Italy was used to validate the algorithm. The findings revealed that the model was an exceptional statistical model using the NN classification methodology. The main challenges faced in the secure software development process are quality and reliability. There are major software cost violations when a software product with errors in its various components is used on the customer’s side. The software warehouse is commonly used as a record keeping repository, which is often needed when adding new features or fixing bugs. Software errors can lead to erroneous and different results. As a result, software programs run late, are canceled, or become unreliable after use. Different social and technical issues are associated with software failure and software defects are the main reasons for deteriorating product quality. In software engineering, the most active research in software domain is defect prediction.This study discusses the bug-fix time forecast model, pre-release release, post-release error and different measurements to predict failures. Predicted results help developers identify and fix potential vulnerabilities, thereby improving software stability and reliability.
INVESTIGATION OF INTELLIGENT CONTROLLER FOR NON-LINEAR SPHERICAL TANK SYSTEM
Authors: Et. al. Ajith B. Singh,
Published: April 2021

Spherical tanks are used to store fluids in many industries such as petrochemical, effluent treatment, and aerospace. Spherical tanks are used as they are highly resistant to internal pressure making them suitable for storing high-pressure materials due to their large volume, small weight, and strong load-bearing capacity. The spherical tanks have the lowest possible surface area to volume ratio. These tanks are preferred due to their capability of balancing pressure in and out of the tank and their ability to minimize the amount of heat that gets inside the tank wall. It is cost-effective when compared to other tanks. But, controlling the water level in the spherical tank is difficult and a highly challenging one. In this article, the aim is to stabilize the level of the spherical tank by using the PID and FUZZY logic controllers. By controlling nonlinear dynamic behavior, uncertainty, time-varying parameters, frequency disturbances and dead time, the stability of the tank is achieved. The mathematical modelling of the spherical system is obtained using first principles design and the stability of the model is analyzed using various techniques. Then, the simulation is done using MATLAB and the responses are obtained and compared for PID and FUZZY logic. Based on these comparisons made on the performance of the PID and FUZZY logic controllers, the results are concluded
DESIGN OF SQUARE MICROSTRIP PATCH MULTI BAND ANTENNA FOR WIRELESS COMMUNICATION USING EBG STRUCTURE
Authors: Et. al. Suresh Akkole,
Published: April 2021

Application of electromagnetic band-gap (EBG) structure and its use in the design of antenna and microwave integrated circuits is becoming more attractive. The recent electromagnetic band-gap structure method is capturing more importance in antenna design due to its uniqueness properties to suppress the propagation of surface waves in microstrip patch antenna. In this paper a square microstrip antenna is designed and its performance parameters are compared with geometry designed on EBG structure.  The square antenna of 29 mm x29 mm  size is designed at 2.455 GHz and analysis is done using IE3D  simulation software. The proposed work mainly focuses on modification of antenna using electronic band gap structure (EBG). The antenna parameters such as Return loss, VSWR, Gain and Bandwidth, with and without EBG are obtained using IE3D simulation tool. The Electromagnetic band-gap structures have been used to improve the performance of the gain of the antennas and radiation patterns. One of the main advantages of electromagnetic band-gap structure is its ability to suppress the surface wave current present on the microstrip antenna. Combining the square patch with EBG structure, the bandwidth of the antenna has been increased by 34.66%, and attained  gain of 44.44%  at resonant frequency around 2.4 GHz as compared to the antenna without EBG..
ANALYSIS OF DRIVER BEHAVIOR IN VEHICLE FOLLOWING AND LANE CHANGING PARAMETERS ON URBAN MID BLOCK SECTIONS
Authors: Et. al. Sowjanya,
Published: April 2021

In mixed traffic situations, there is weak or no lane behavior of the driver much more complicated where vehicle and driver behavior show a huge difference between them. Road traffic driving behavior on urban midblock sections is one of the most complex phenomena to be examined particularly in heterogeneous traffic conditions. This is often attributed to the capacity of the road section and the traffic flow features at the macroscopic and microscopic level of a road section. Very few researchers have attempted to investigate these features in heterogeneous environments because of the lack of adequate information gathering methods and the amount of complexity involved. In this background, an access controlled mid block road section was selected for video data collection. The main objectives of this study include developing vehicular trajectory data and analyzing the lane changing and vehicle following behavior of driver on the mid block section considering the relative velocities and relative spacing between various types of vehicles under heterogeneous traffic conditions.  The videos were collected from urban roadway in the Kurnool district of Andhra Pradesh. The length of the stretch is 120m and the width is 7.0 m. The data was extracted to know the variations in terms of longitudinal and lateral speeds, velocities, vehicle following and lane changing behavior of the drivers. The data extracted was smoothened by moving average method to minimize the human errors. Lateral amplitude of the vehicles of various types was analyzed. The study revealed that vehicles in the mixed stream, in general and in particular, Bikes and Autos particularly move substantially in the lateral direction.
ARRIVING AT OPTIMAL COST FOR A SUSTAINABLE PRODUCT USING AN INTEGRATED LCA-SCM MODEL
Authors: Et. al. Suparno Bhatta,
Published: April 2021

Globalization has unleashed a new era of prosperity in economic terms. This has completely changed our outlook towards lifestyle. The recent surge of consumption in the past few decades has led to the escalation in the production of goods which in turn puts a huge burden on the environment. The increasing over consumption of resources has created a sense of urgency to track the level of expenditure as well emissions from a product. One of the major concerns related to the development of green products is the cost factor that comes into play while sourcing the alternate green materials. Identifying the alternate green material increases the overall manufacturing cost for the company. There are a lot of Life Cycle Assessment (LCA) models that look into the environmental quality of a product. Similarly, there are many Supply Chain Management (SCM) models that look into the cost of the product. However very few have researched the combination of both LCA and SCM. There is a need to establish a balance between the cost and the environmental quality of a product. This paper investigates the cost of manufacturing sustainable products by looking into existing LCA and SCM models.

Published: April 2021

The entire media and entertainment industry are going through unprecedented changes in this age of digital disruption. The rise of the Over-The-Top (OTT) platform has transformed consumer experience and expectations. OTT players (Netflix, Amazon Prime Video, Hulu, Disney+, etc.) offer a wide array of diverse choices of content while enabling consumers to choose their content, watching time, and place independently. OTT platforms and digital media have already seen increasing popularity across locations and demographics. Adding to the momentum, due to the COVID-19 pandemic, social lives have shifted to online, people are restricted to their homes, so inclination towards OTT and digital media has accelerated significantly. Consumer behavior is undergoing profound change as the world adjusts to this new normal. This study aims to understand the changing consumer behavior towards the adaptation of the OTT platform during the COVID-19 pandemic.
Regional Calibration of Hybrid Ground-Motion Simulations in Moderate Seismicity Areas: Application to the Upper Rhine Graben
Authors: Razafindrakoto Hoby N. T. , Cotton Fabrice , Bindi Dino , Pilz Marco , Graves Robert W. , Bora Sanjay
Published: April 2021

This study presents the coupling of the spectral decomposition results for anelastic attenuation, stress drop, and site effects with the Graves-Pitarka (GP) hybrid ground-motion simulation methodology, as implemented on the Southern California Earthquake Center (SCEC) broadband platform (BBP). It is targeted to applications in the Upper Rhine graben (URG), which is among the seismically active areas in western Europe, yet a moderate seismicity area. Our development consists of three main steps: (1) calibration of regional high-frequency (HF) attenuation properties; (2) modification of the hybrid approach to add compressional waves in the HF computation and examine various strategies to evaluate site amplification factors in the Fourier domain (e.g., VS30-based or site-specific factors); (3) testing of the simulations using earthquake records from the URG (3.7<Mw<5). The validation process of the simulated time histories is performed first on rock sites, and, then subsequently at all stations, whatever their site conditions. The performance of the simulations for rock sites is assessed through the standard validation technique in the BBP (comparison of the waveforms, intensity measures, and estimation of the response spectra model bias). We additionally compare the Fourier amplitude spectrum of the simulations and observations, and compute their corresponding bias. The results show that the simulated ground motions match the general characteristics of the recorded motions, and that the model bias generally fluctuates around zero across the broadband frequency range. Hence, the hybrid ground-motion methodology implemented in the SCEC BBP can be successfully applied outside high-seismicity areas and outside those areas for which it had been generally calibrated. Our results also show that HF modification and calibration were necessary to improve the fits with the observation, and demonstrate the potential benefits of using site-specific amplification factors compared to VS30-based amplification factors.
Antecedentes y viabilidad de alternativas en el actual sistema-mundo
Authors: Tortosa José María
Published: April 2021

El artículo recorre las sucesivas coyunturas del sistema-mundo, desde la Guerra Fría a nuestros días, haciendo ver que las alternativas han estado siempre presentes incluso cuando se las negaba. Con más razón lo están en la actualidad, cuando el sistema se encuentra muy alejado del equilibrio y, por tanto, necesita un menor aporte de energía para que se produzca un cambio en el mismo. Los desequilibrios actuales vienen reflejados por un lado en la aparición de los países emergentes, en la crisis de hegemonía y la existencia novedosa de países en vías de subdesarrollo y, por otro, por la acumulación de crisis interconectadas (económica, alimentaria, energética y ambiental aunque también democrática).

Authors: Fomin I. V. , Vinogradova N. G. , Polyakov D. S. , Pogrebetskaya V. A.
Published: April 2021

Aim    To present clinical characteristics of patients after hospitalization for acute decompensated heart failure (ADHF) and to analyze hemodynamic indexes and compliance with the treatment at two years depending on the conditions of outpatient follow-up.Material and methods    The study included 942 patients with chronic heart failure (CHF) older than 18 years who had been hospitalized for ADHF. Based on patients’ decisions, two groups were isolated: patients who continued the outpatient follow-up at the Center of CHF (CCHF) (group 1, n=510) and patients who continued the follow-up in outpatient multidisciplinary clinics (OMC) at their place of residence (group 2, n=432). The clinical portrait of patients was evaluated after ADHF, and hemodynamic parameters were evaluated on discharge from the hospital. Also, the patient compliance with the treatment was analyzed during two years of follow-up. Statistical analysis was performed with Statistica 7.0 for Windows.Results    The leading causes for CHF included arterial hypertension, ischemic heart disease, atrial fibrillation, and type 2 diabetes mellitus. With the mean duration of hospitalization of 11 inpatient days, 88.1 % and 88.4 % of patients of groups 1 and 2 were discharged with complaints of shortness of breath; 62 % and 70.4 % complained of palpitations; and 73.6 % and 71.8 % complained of general weakness. On discharge from the hospital, the following obvious signs of congestion remained: peripheral edema in 54.3 % and 57.9 %; pulmonary rales in 28.8 % and 32.4 %; orthopnea in 21.4 % and 26.2 %; and cough in 16,5 % and 15.5 % of patients of groups 1 and 2, respectively. For the time of hospitalization, CHF patients did not achieve their targets of systolic BP (SBP), diastolic BP (DBP) and heart rate (HR). Patients of group 1 achieved the recommended values of SBP, DBP and HR already at one year of the follow-up at CCHF. Patients of group 2 had no significant changes in hemodynamic indexes. At one and two years of the follow-up, group 2 showed a considerable impairment of the compliance with the basis therapy for CHF compared to group 1.Conclusions    During the short period of hospitalization (11 inpatient days), the patients retained pronounced symptoms of HF and clinical signs of congestion and did not achieve their hemodynamic targets. The patients who were followed up for a long time at CCHF were more compliant with the basis therapy, which resulted in improvement of hemodynamic indexes, compared to the patients who were managed in OMS at the place of residence.

Published: April 2021

Selenium is an important micronutrient that is essential for the functioning of the human body. Being a component of the active center of several antioxidant enzymes selenium prevents cell injury by free radicals. Decline in selenium-containing enzymes results in progression of oxidative stress and chronic inflammation, which are considered as possible causes for the development of many cardiovascular diseases. This review focuses on mechanisms for prevention of myocardial and vascular injury through the adequate selenium supply to the body. The importance of monitoring and correction of the selenium status in appropriate patients is underlined.

Published: April 2021

Aim    To develop a new, modified protocol for transesophageal atrial electric stimulation (TEAES), which would significantly enhance the diagnostic value of stress echocardiography and reduce the duration of the test in patients with ischemic heart disease (IHD).Material and methods    This study included 101 patients (80 men and 21 women aged 55±9 years) with suspected or documented diagnosis of IHD who were divided into two homogenous groups. Group 1 (51 patients) underwent stress echocardiography (stress-EchoCG) according to a standard protocol (SP) for TEAES and group 2 (50 patients), underwent stress-EchoCG according to a modified protocol (MP). In addition to stress-EchoCG with TEAES, selective coronary angiography was performed for all patients. The development of the new method for evaluating occult coronary insufficiency was based on comparison of SP and MP for TEAES with stress-EchoCG with data of coronary angiography.Results    In both groups, significant differences in values of systolic and diastolic blood pressure were absent. However, the values of achieved heart rate were significantly different: 141±11 (TEAES SP) and 155±10 (TEAES MP) bpm (p=0.01). There was also a difference in the duration of the TEAES protocols: 15±3 and 5±2 min, respectively (p=0.006). The use of the modified TEAES protocol for detecting transient disorders of left ventricular myocardial local contractility increased the sensitivity, specificity and accuracy of the test from 76 %, 87 %, and 80 % to 83 %, 92 %, and 86 %, respectively. The most significant differences were found in the area supplied by the circumflex artery: the SP and MP sensitivities were 63 % and 75 %, respectively (p<0.05) and the SP and MP accuracies were 81 % and 90 %, respectively (p<0.05).Conclusion    Evaluation of occult coronary insufficiency by stress-EchoCG with the TEAES MP as compared to the TEAES SP provides a gentler procedure regimen for the patient due to a shorter duration of the test and at the same time improves the diagnostic significance of this method in IHD patients.
Results of Computed Tomographic Coronary Angiography in Comparison with the Table of Pretest Probability of Chronic Coronary Syndrome
Authors: Chepurnenko S. A. , Nasytko A. D. , Shavkuta G. V. , Kostenko V. L.
Published: April 2021

Aim        To compare results of computed tomography coronary angiography (CTCA) with a table of pretest probability of chronic coronary syndrome (CCS) taking into account the following key variants: abnormality, microvascular damage, nonobstructive or obstructive atherosclerotic damage.

Material and methods        50 patients (39 men, 20 women) aged 30 to 67 years were evaluated with a computed tomography scanner PHILIPS Brilliance iCT SP 128. A high pretest probability of ischemic heart disease was found in 44 % of cases and medium in 40%.

Results   According to CCS data, coronary artery (CA) pathology was not found in 28 % of patients. CA hypoplasia was observed in 4 % of patients. 22 % of patients had muscular bridges narrowing the CA lumen during systole by 40-50%. In 26 % of cases, CA had minimal and early stenoses. Moderate and pronounced stenoses were observed in 20% of cases. In one case, there was a total occlusion of the circumflex branch. Calcinates were found in 9.1 % of patients with muscular bridges, in 61.5 % of patients with minimal and early stenoses, and in 80% of patients with moderate and pronounced stenoses. In the group with “clean” CA and congenital defects, calcinates were absent. The mean value of pretest probability was the highest in the patient group with moderate and pronounced stenoses, 22.5±13.13. It was significantly higher than in the group with muscular bridges (р=0.045) and congenital pathology of CA (р=0.01). At the same time, this value did not significantly differ from the group with “clean” CA and the group with minimal and early stenoses. Based on the study results, 2 bypass surgeries and 5 CA stentings were performed.

Conclusion            Thus, the table of pretest probability of ischemic heart disease does not provide a differential diagnosis and evaluation of the nature of CA damage as compared to results of CTCA.

Published: April 2021

Aim        To compare effects of neuromuscular electrostimulation (NMES) with various intensity of induced muscle contractions on its tolerance and effect on physical work ability in elderly patients admitted for chronic heart failure (CHF).

Material and methods        The study included 22 patients older than 60 years admitted for decompensated CHF. NMES was performed from the 2nd or 3d day of stay in the hospital to the discharge from the hospital. Patients choose the stimulation regimen themselves based on the result of the first session: the high intensity to achieve maximum tolerable muscle contractions (group 1) or the lower intensity to achieve visible/ palpable muscle contractions (group 2). Prior to the onset and after the completion of the training, the 6-min walk test (6MWT) was performed and the general condition of the patient was assessed with a visual analogue scale (VAS).

Results   More patients, mostly women, chose the less intensive NMES (14 vs. 8). The groups did not differ in age, comorbidity, and functional condition. Both groups achieved considerable increases in the 6MWT distance (7.3 [5.6; 176] and 9.8 [7.0; 9.9] %, respectively, p>0.05) and VAS scores without a significant difference between the groups. Among the patients who were compliant with continuing NMES after the discharge from the hospital, 69% were patients of the group of the less intensive stimulation.

Conclusion            The less intensive NMES (with achieving visible muscle contractions) was characterized by better tolerance and better compliance in elderly patients with decompensated CHF compared to the more intensive NMES (with achieving maximum contractions), but the less intensive NMES was not inferior to the more intensive NMES in effectiveness.

Authors: Simon Trishell , James Chanique
Published: April 2021

Gonococcal orbital cellulitis is an infrequent presentation within the pediatric age group, with very few cases reported in literature. Even rarer, is the nonvenereal transmission via fomites. Careful physical examination with detailed social evaluation must always be obtained in any child with a gonococcal infection to look for signs or evidence of sexual abuse. This paper reports a 3-year-old male who developed a left preseptal and postseptal gonococcal orbital cellulitis via a nonsexual mode of transmission.

Authors: S. Shankarlinga , Kyavater Basavaraj S. , Rana Manik
Published: April 2021

Background: Mechanoreceptors plays a vital role in knee mechanics. Since there are controversies surrounding the overall recovery time of proprioception following surgery, it is necessary to define the factors affecting proprioceptive recovery after anterior cruciate ligament reconstruction and to investigate the relationship between proprioception and muscle strength following surgery.

Methods: Current study is combined prospective and retrospective study done at K. S. hospital Koppal, spanning for a period of one year (December 2019 to December 2020). All patients presented with isolated anterior cruciate ligament (ACL) tear were included in the study. Patients were treated by arthroscopic ACL reconstruction with hamstring graft only and followed up for a period of year. Outcome measures include centre of mass proprioception in AP and medio-lateral direction and muscular strength through force gauze in Newton.

Results: 26 patients (mean age 33) were included in the study, all ACL tears were treated by arthroscopic ACL reconstruction with hamstring graft and they underwent varying period of rehabilitation.

Conclusions: This study shows that our understanding of biomechanics of ACL reconstructed knees is still evolving, and proprioception is found to be a key factor in determining post-op recovery. ACL remnant preservation intra-op along with proper mechanical positioning of the graft may help in better proprioception and functional outcome following the reconstruction.

Published: April 2021

When older adults face age‐related life challenges, anticipating what to expect and how to access potential coping strategies can both prevent and provide the possibility of easier recovery from crises. Aging‐Related Preparation (ARP) is defined as the continuum of thoughts and activities about how to age well, often beginning with the awareness of age‐related changes, or the anticipation of retirement, and concluding with specifying end‐of‐life wishes. In the current paper, we introduce the concept of ARP and related formulations regarding plans for aging well, describe both predictors and outcomes of ARP for several the domains of ARP, and consider the elements of ARP within the context of existing social policy. We conclude that ARP is determined by a variety of influences both intrinsic to the older person (e.g., personality, cognitive ability, beliefs about planning, problem‐solving skills), linked to social class and education, as well as dependent on family structures, access to and knowledge of options, services, and local community resources, and social policy. We further provide evidence that ARP has positive effects in the domain of pre‐retirement planning (for retirement adjustment), of preparation for future care (for emotional well‐being), and of ACP (for a good death). However, other domains of ARP, including planning for leisure, housing, and social planning are under‐researched. Finally, we discuss policy implications of the existing research.
Política Criminal de Drogas: afronta a direitos fundamentais e desproporcionalidade sob o argumento de proteção à saúde
Authors: Quadros Doacir Gonçalves de , Figueiredo Daniel José de
Published: April 2021

No imaginário das pessoas, traficantes armados e de pés descalços são responsáveis pela sensação de insegurança que toma conta dos centros urbanos, principalmente os de maior porte. Nossa sociedade de risco tende a flexibilizar direitos e garantias fundamentais em detrimento de uma supervalorização da segurança. No que se refere a drogas, a doutrina aponta ofensas a vários princípios constitucionais: isonomia, liberdade, autonomia do indivíduo, intimidade, vida privada. O Supremo Tribunal Federal, ainda que com o voto de três dos seus onze ministros, direciona-se pela inconstitucionalidade do artigo 28 da Lei de Drogas (Lei 11.343/06). O III Levantamento Nacional sobre o Uso de Drogas traz informações relevantes sobre a situação na população brasileira. Busca-se, por meio de uma revisão da bibliografia, verificar a hipótese desconformidade da política criminal de drogas face a princípios constitucionais como vida, liberdade, autonomia, vida privada e proporcionalidade. Conclui-se pela existência de uma afronta direitos e garantias fundamentais presentes na Constituição de 1988, indicando a necessidade de implementação de medidas de descarceirização, despenalização e legalização, assim como as que estão em curso em outros países.

Igualmente diferentes: a identidade de gênero de crianças e adolescentes no Chile
Authors: Ballesté Isaac Ravetllat
Published: April 2021

Nos últimos tempos, assiste-se ao aparecimento de novas realidades no interior do coletivo trans*, a dar visibilidade a situações ou circunstâncias que, até há poucos anos, eram completamente invisíveis e absolutamente silenciadas. Esse é o caso, sem ir muito além, da questão da transexualidade na infância e na adolescência. Parece que vive-se os momentos iniciais daquilo que se está chamando de uma mudança de paradigma: o deixar de entender a experiência das crianças e adolescentes trans* como uma desordem identitária ou um problema e passar a considerá-la como um conjunto de construções e eleições de caráter personalíssimo, de trajetórias heterogêneas, fluidas e mutáveis, às quais a lei não deve nem pode dar as costas. É por isso que, no presente artigo, se analisará o contexto social e legal que rodeia a vida das crianças e dos adolescentes trans* no Chile atual, incidindo particularmente naqueles aspectos que caracterizam o direito à identidade (de gênero) naqueles casos em que sua titularidade recai sobre uma pessoa menor de idade.

BACKGROUND This case series was conducted to evaluate the intraoperative and post-operative outcomes of fracture shaft of humerus managed by indirect reduction and minimally invasive plate osteosynthesis (MIPO) via anterior approach. METHODS In this case series 26 diaphyseal fractures of the humerus treated with MIPO, between June 2017 and February 2020 at a tertiary care hospital were included. All the patients were followed up for a minimum period of 2 years postoperatively. The objective was to evaluate these cases clinically for shoulder and elbow range of motion and document any complications. Other parameters such as duration of surgery and radiological time for fracture union were also documented. RESULTS The mean duration for surgery was 86.5 minutes. The University of California Los Angeles (UCLA) shoulder scoring system rated 18 patients (69.2 %) as excellent outcome, 07 patients (26.9 %) as good outcome, and 1 patient (3.8 %) as fair outcome. The MAYO Elbow Performance Scoring system rated 20 patients (76.9 %) as excellent outcome and 06 patients (23.1 %) as good outcome. About 96 % of patients achieved fracture union by the end of 16 weeks post-operatively (mean 13.4 weeks). No complications related to infection, iatrogenic radial nerve injury or implant failure were noted in the study. 4 cases had varus angulation deformity but did not affect shoulder or elbow function. CONCLUSIONS MIPO is a safe and effective technique for the management of diaphyseal humerus fractures, with early fracture healing, less risk of complications such as infection and iatrogenic radial nerve injury, along with a cosmetically acceptable scar.

BACKGROUND Significant causes of corneal blindness worldwide are ocular trauma and corneal ulceration that are often under reported. They may be responsible for 1.5 - 2.0 million new cases of monocular blindness every year. Corneal ulceration in developing countries has only recently been recognised as a silent epidemic. Infectious keratitis is one of the leading causes of blindness but in most cases these infections represent preventable or treatable ophthalmic diseases. Important predisposing factors related to corneal ulcers are trauma, chronic ocular surface disease, contact lens usage, ocular surgery, corneal anaesthetics abuse, diabetes mellitus, vitamin deficiency and immuno-deficiencies. This work is proposed to study the prevalence, clinical and lab diagnosis and management of suppurative corneal ulcer. We wanted to study the socio-demographic profile, microbiological investigation and treatment outcome of patients with corneal ulcer. METHODS This is a prospective study conducted among patients presenting with corneal ulcer at a tertiary level Government Medical College, Ajmer, Rajasthan. RESULTS Trauma comes out as a major predisposing factor for the development of corneal ulcer. 18.1 % of the study subjects had bacterial corneal ulcer and 37.7 % had fungal ulcer. More than half of the patients showed good prognosis on follow up. There was good response in most of patients, 51.2 % improved in first week which increased to 57.4 % at the time of second follow up. The most common bacterial species responsible for corneal ulcer was found to be staphylococcus followed by pseudomonas. CONCLUSIONS Bacteria and fungi are a frequent cause of ulcerative keratitis. Microbiological work up is an essential tool in the diagnosis of these infections which should not be under-rated. Timely administration of species-specific treatment certainly results in early resolution of keratitis followed by satisfactory visual outcome. Late or inappropriate treatment worsens the condition resulting in corneal perforation and increased morbidity. KEYWORDS Prospective, Corneal Ulcer, Bacterial, Fungal, Infectious
The Features of the Connective Tissue Morphological Change During a Skin Scar Formation After a Cesarean Section

Published: April 2021

During a skin scar formation morphofunctional change of skin structures takes place. The action of external mechanical factors can lead to prolongation of reparative processes in the scar and to the change in the morphometric parameters of its components.Research goal: to study the features of the skin structural components morphological change in secundipara women during a connective tissue scar formation after a cesarean section.Material and methods. The materials for the study were the fragments of a connective tissue scar with an adjacent area of intact skin taken from 30 women after operative delivery by Caesarean section. On scanning electron microscopy, morphometric parameters were measured, which enabled to assess the cell composition and the changes in the fibrous components of the connective tissue scar.Results. Analyzing the thickness of the fibers in the same age group, the thickening of the fibers was observed in direct proportion to the number of births. Comparing different age groups with the same number of births, the thinning of collagen fibers was observed. The most pronounced changes were observed in women having three or more deliveries.Conclusion. Under the influence of the stretching force in the skin, a structural change of the connective tissue scar occurs. This change is due to the thickening of collagen structures, the decrease in the density of collagen structures location, the increase in the number of lymphocytes and macrophages.

In the modern aspect, the relevance of damage to the medial cutaneous nerve of the arm during surgical interventions in the axilla and brachial region is displayed. Due to the superficial location in the subcutaneous layer, the nerve is most often subject to accidental damage, including in brachioplasty, axillary lymphodissection, breast cancer surgeries and breast augmentation. The material on variant anatomy, macroscopic structure and topography of the nerve is presented. The medial cutaneous nerve of the arm is formed from the medial cord of the brachial plexus, in some cases - from the posterior cord; isolated cases of the absence of the nerve are described. When exiting the axilla at arm level, the nerve penetrates into the deep brachial fascia, passes in the subcutaneous layer medially from the basilic vein of the arm and provides sensitive innervation to the skin of the medial surface of the arm, the skin of the medial epicondyle and the olecranon of the ulna. The medial cutaneous nerve of the arm has an average of 7-8 cutaneous branches, which are characterized by significant variability in the location under the skin. The significance of the medial cutaneous nerve of the arm in clinical practice, namely, in surgical interventions in the arm region, the development of neuropathic pain syndrome, brachial plexus blockages and the diagnosis of nerve damage, medial cord and inferior trunk of the brachial plexus. This review summarizes recent data, which allow to form a more complete picture of the clinical anatomy of the medial cutaneous nerve of arm and the possibilities of its use in reconstructive surgery. An especially relevant area is the possibility of using a medial skin flap of the arm with directed innervation by the medial cutaneous nerve of the arm for reconstruction and restoration of the sensitivity of the nipple-areola complex.

Background and Purpose:Children with acute myeloid leukemia and relapses of leukemia are at high risk of developing fungal infections and need antifungal prophylaxis. This study aimed to compare the efficacy and toxicity of two different dosage regimens of voriconazole (VRCZ) during prophylactic administration in children with malignancyand neutropenia.
Materials and Methods:This prospective study was conducted at the Belarusian Research Center for Pediatric Oncology, Hematology, and Immunology fromMay 2017 to December 2019. The present study included 21 Caucasian patients with malignant hematological diseases (20 patients with acute myeloid leukemia and relapses of leukemia and 1 patient with Non-Hodgkin's lymphoma) aged 2-18 years. All patients were randomly divided into two groups that received different dosage regimens of VRCZ prophylaxis. Patients in the “high-dose” group received VRCZat a dose of 9 mg/kg twice a day PO, or 8 mg/kg twice a day IV without a loading dose (children of 2-11 and adolescents and of 12-14 years old with.
Results:In the high-dosegroup (n=20 episodes of prophylaxis), invasive fungal infections (IFI) signs were recorded in one (5%) case. In the low-dose group (n=20 episodes), IFI signs were observed in six (30%) cases (P=0.0375). The residual serum concentration was significantly higher in patients who received high doses of VRCZ (p <0.0001). Most patients with IFI (n=6, 86%) had a mean value (i.e.,)
Conclusion:The likelihood of IFI was significantly lower in children who prophylactically received VRCZ in high doses (P=0.0375) and had ≥ 0.74 μg/ml residual serum concentration of the medication (P=0.0258). Residual serum concentration of VRCZ reached a plateau by day sixth of the treatment. In children, the dosage was the only highly significant factor affecting the metabolism of VRCZ.
