Authors: Berghuijs Joantine , Liefbroer Anke I.
Published: June 2022

Spiritual caregivers often meet clients with another spiritual or religious orientation than their own, as they care for clients from a diversity of backgrounds and for clients who draw from multiple religious traditions. How do spiritual caregivers deal with religious diversity in their own lives? Do they themselves draw from more than one religious tradition? How do they function in a multireligious environment? Are they willing to provide interfaith spiritual care and do they see themselves as able to do so? What challenges do they see for the future? A survey was conducted among spiritual caregivers in healthcare settings, the military and penitentiary institutions in the Netherlands (n=208) to answer these questions. Implications of the results for the future of spiritual care are discussed.

Published: June 2022

This study examines the digital economy shown by internet users with economic growth, education, health, and inflation.This research examines data from 2000 until 2020 to be able to produce "autoregressive vectors" that may be used to evaluate the causal link between variables. Based on secondary data from the World Bank, the following multivariate regression model was used to investigate the causal link between Internet Users, Gross Domestic Product, Education, Health and Inflation in Indonesia. The results of this study are quite surprising where technological literacy in Indonesia actually suppresses GDP, this shows that the use of the internet for Indonesian people in production is not yet optimal. Or most Indonesians use the internet as entertainment and consume digital products from abroad so internet technology literacy suppresses GDP. However, internet literacy supports education in Indonesia where education in Indonesia uses internet technology massively. Education itself encourages internet literacy in Indonesia significantly. However, the literacy of internet users actually suppresses the health sector where the health sector in Indonesia during the research period was dominated by offline and the health sector did not provide a significant boost to internet literacy in Indonesia. The digital economy in Indonesia has been proven to suppress inflation, although not significantly. This illustrates that the digital economy has the potential to suppress inflation and in the current case of Indonesia, the digital economy is not yet optimal currently the majority of internet users in Indonesia are users or consumers of digital products from countries outside Indonesia so they have not been able to encourage domestic economic growth.

Authors: Gonçalves Larissa Galindo , Silva dos Reis Welinton Rafael , Parra Marianna de Paiva , Kassis Elias Naim
Published: June 2022

Introduction: In the context of tooth extraction and aesthetic care, steps are needed for tooth extraction. Alveolar bone resorption after tooth extraction often leads to situations where the long-term function and esthetic success of dental implant restorations is a challenge. Thus, the Socket shield has been described as an alternative technique to maintain the alveolar ridge in the placement of immediate implants. Objective: Conducted a concise systematic review of key considerations and clinical outcomes of minimally traumatic treatment of tooth extraction and dental implants. Methods: The present study followed a concise systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. The present study was carried out from January to March 2022. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 112 articles were found. A total of 47 articles were fully evaluated and 26 were included in this study. The results suggest that the adjunctive use of connective tissue grafting is not mandatory to achieve successful esthetic results for well-planned immediate implant placement with non-functional immediate provisional restoration in a fresh extraction socket. Still, the success/modified success rate, survival, mean resorption of the oral plate, and patient satisfaction, there were no differences between immediate implants placed with a flap or with an envelope flap of minimal thickness.

Medical devices associated adverse events under Materiovigilance Programme of India in a Tertiary Care Hospital of Tribal District of Odisha
Authors: Samal Satyajit , Naik Manas , Behera Sripada
Published: June 2022

Background: A materiovigilance program is a system that is used for the identification, collection, and reporting of possible adverse reactions resulting from the use of medical devices. This monitoring program ensures the safety of patients and aids the post-marketing surveillance process. The Materiovigilance Programme of India (MvPI) was launched on July 6, 2015.

Aims and Objectives: The primary objective of the study was to generate evidence based data on the safety of the medical devices used in our institute and to analyze the risk benefit ratio of reported adverse events of medical devices and to communicate the safety information to the stake holders. The secondary objective was to educate and advocate the concept of MvPI and creating a culture of adverse events reporting among health workers.

Materials and Methods: A retrospective study was conducted after receiving clearance from the Institutional Ethical Committee, Saheed Laxman Nayak Medical College and Hospital (SLN MCH), Koraput. Data about Medical Device-Associated Adverse Events (MDAEs) were collected from MDMC, SLN MCH, Koraput, for the period from October 2019 to February 2022. MDAE reports were collected by a materiovigilance associate during the period from October 2019 to February 2022. Events were reviewed to verify whether or not they were documented in patient’s electronic records and a database of devices was created, which included the events associated with each device. Device-related MDAEs were classified by patient characteristics and the medical devices used.

Results: In the 15-month study period, a total of 56 cases of MDAE were reported to MDMC, SLN MCH, Koraput. Of these, 17.9% MDAEs (10 cases) were adverse events related to surgical gloves, 8.9% (five cases) were associated with pulse oximeters, 7.14% of cases (4 cases) were due to glucometer malfunctioning, and 7.1% were related to HIV diagnostic kits such as false positives and false negatives. Adverse events such as skin rashes, irritation on skin, itching, redness of eyes, and gum bleeding in patients with dental braces were reported. A majority of device defects involved inaccuracy in the data reported by the devices (seen in 10.7% of cases), while six cases were due to device malfunctioning.

Conclusion: This study shows only the tip of iceberg of the reporting trends of MDME. There is inequality in reporting by different grades of health care workers and from different departments. It highlights the necessity of conducting awareness programs, training and workshops regularly. Device-related safety and reporting of device-related adverse events should be subject of attention and further research.

Authors: Gopinath Sangeetha , Murukesan Prasanth , PT Ramani
Published: June 2022

Background: The studies in children regarding the effects of inhaled corticosteroids (ICS) on the carbohydrate metabolism are scant in India. This study was undertaken to determine if there is any effect of inhaled steroids on the glycemic control.

Aims and Objectives: The aim of the study was to analyze the pattern of glycated hemoglobin (HbA1c) levels in children with persistent asthma, before and after using prophylactic doses of ICS and to evaluate and compare HbA1c levels separately in those taking budesonide and in those taking fluticasone or other steroids.

Materials and Methods: It was a prospective and observational study, based on a study proforma. Children of 2–12 years of age, diagnosed with mild-to-moderate persistent asthma, attending the Asthma Clinic at Paediatrics Department of SAT Hospital, Government Medical College, Thiruvananthapuram were included in the study. The diagnosis of asthma and the severity was recorded according to Global Initiative for Asthma guidelines.5 The sample size was calculated to be 40. Type, dose, and frequency of administration of ICS and other coprescribed drugs were recorded on an asthma diary and entered into the study proforma. HbA1c levels were measured in children before they were started on ICS, on the same day of visit using high perfusion liquid chromatography technique and repeated after 6 months. Student’s t-test was used to compare mean values between two groups.

Results: Mean age of patients is 5.75. About 62.5% of patients were males. About 72.5% of the patients had a diagnosis of moderate persistent asthma. The mean HbA1c before the treatment with ICS was 5.36 and after the treatment is 5.37 and the difference was not significant.

Conclusions: There was no significant change in HbA1c levels with the use of ICS.
Awareness and outlook of health-care professionals regarding materiovigilance in a tertiary care teaching hospital in South Rajasthan
Authors: Tantia Ruchi , Atray Meena , Agrawal Apurva
Published: June 2022

Background: Post-marketing surveillance regulates the safety, quality, and performance of medical devices (MDs). Medical professionals play a key role in the monitoring and reporting of MD Adverse Events (AEs). Since the launch of Materiovigilance (MV) Programme of India, very few published studies were found regarding reporting of MDAE.

Aim and Objective: This study aims to know about awareness and outlook of medical professionals regarding MV.

Materials and Methods: A cross-sectional study done among medical professionals of various specialties in a tertiary care teaching hospital in South Rajasthan. A pre-validated questionnaire was circulated to 200 doctors containing questions related to knowledge, attitude and practice of MV.

Results: About 58.6% of the doctors came to know about the term MV during this study. About 76.7% of participants knew that MD could lead to an AE, but only 11.2% of the participants had the correct knowledge of how to report an AE related to MD. About 66.8% of participants had positive attitude regarding reporting of AE, 23.7% reported the event and 66.6% did not report as they found them mild.

Conclusion: Majority of doctors had the knowledge about reporting of AEs, but they were largely unaware of the term MV. Knowledge regarding where to report is very limited. Despite adequate level of knowledge, reporting practices are very limited. Hence, there is a need for regular sensitization and training programs to foster the habit of reporting AE related to MD even if they are mild.

Published: June 2022

Background: In a nationwide survey conducted in the Indian Council of Medical Research- INdia DIABetes study (Phase-1) 2014 on physical activity and inactivity patterns, overall, 392 million individuals in India are physically inactive. Physically active medical students tend to recommend physical activity for patients or at-risk individuals in their future practice. Exercise is a subset of physical activity that is planned, structured, and repetitive which helps in achieving physical fitness.

Aim and Objectives: The aim of the study was to assess the prevalence of physical activity (PA) and physical fitness among medical students and to correlate both.

Materials and Methods: This is a cross-sectional study, in which physical activity level was assessed using Global Physical Activity Questionnaire. Physical fitness using Harvard step test, hand grip dynamometer, sit-up and push-up test, shoulder – flexibility test, body mass index, and body adiposity index was assessed among 150 medical students in a tertiary care hospital.

Results: Physical activity level when analyzed, 16% of students performed low PA, 74% belonged to moderate PA Group, and 10% in high PA group. When mean metabolic equivalent of task min/week attained by study population in three domains of physical activity (work/travel/recreation) was analyzed, results showed no significant difference between males and females in different domains of physical activity.

Conclusion: Although the students met the recommended physical activity as per the World Health Organization, physical fitness was not achieved up to the desired level. No correlation was noted between physical activity and physical fitness among medical students.

Authors: Gowlikar Sai , Konda Jayaprakash , Patnaik Prashanth , S Mahammad
Published: June 2022

Background: Migraine is a most common and highly prevalent neurologic disorder characterized by recurrent moderate-to-severe headaches often in association with a number of autonomic nervous system symptoms. Sodium valproate and topiramate are the two newer antiepileptic agents which are commonly prescribed for the migraine prophylaxis in India.

Aims and Objectives: The aims of the study were as follows: (1) To compare the efficacy of sodium valproate 15–30 mg/kg/day and topiramate 2–3 mg/kg/day as prophylactic therapy for migraine in adults and (2) to study cost-effectiveness and safety profile of sodium valproate and topiramate.

Materials and Methods: It is an open-label comparative study; 100 migraine patients of age group between 20 years and 50 years of both sexes were enrolled in the present study according to the inclusion criteria. Patients were diagnosed as migraine as per the International Criteria For Headache Disorders-3. Before starting treatment and after diagnosis, investigations have done, that is, complete blood picture, liver function test, renal function test, random blood sugar, and thyroid profile. Randomization was done by choosing every alternate patient and study drugs were prescribed. One hundred patients were divided into two groups, Group-A: 50 patients administered Tab. sodium valproate 500 mg twice daily orally and Group-B: 50 patients administered Tab. topiramate 150 mg once daily orally for a period of 6 months.

Results: In Group-A, the severity of pain value before starting treatment was 6.440 ± 2.130 which is reduced to 1.820 ± 1.024 at the end of the treatment which was statistically significant (P < 0.0001) and the frequency of headache value before starting treatment was 4.220 ± 1.298 which is reduced to 1.320 ± 0.7407 at the end of the treatment, P < 0.0001 which was statistically significant. In Group-B, the severity of pain value before starting treatment was 6.200 ± 2.119 which is reduced to 1.840 ± 0.9765 after starting treatment which was statistically significant (P < 0.0001) and the frequency of headache value before starting treatment was 4.300 ± 1.199 which is reduced to 1.340 ± 0.6884 after starting treatment, P < 0.0001 which was statistically significant. In between the two groups severity of migraine pain and headache frequencies the P value was statistically significant.

Conclusion: The results of the present study demonstrated that both sodium valproate and topiramate were well tolerated, having similar efficacy in reducing the severity of the pain, headache frequencies, and improving the quality of life. Sodium valproate is preferred because of cost-effectiveness.

Authors: Balasubramanian Ashwin , Khandelwal Prakash , Zaveri Harshit , Gandhi Miti , Ray Ipseeta , Bhusare Dattatray
Published: June 2022

Background: There exists a treatment dilemma regarding the optimal and effective use of therapeutic drugs (hydroxychloroquine/chloroquine/azithromycin) for COVID-19. Furthermore, with changing guidelines, the data on drug utilization patterns across India are limited. Hence, this study was conducted to assess the prescription pattern and drug utilization trends in COVID-19 patients with the aim to study the drug utilization pattern in patients affected with COVID-19 in a dedicated COVID-19 hospital.

Aims and Objectives: The objectives of the study are as follows: (1) To study drug utilization patterns according to the severity of the disease. (2) To study the prevalence of adverse drug reactions (ADRs).

Materials and Methods: Data were collected retrospectively from 100 medical records of patients ≥18 years irrespective of sex admitted in the COVID ward and ICU of a dedicated COVID hospital from May to August 2020. Pregnant and lactating women were excluded from the study. ADRs reported were also analyzed.

Results: About 71% were mild in this study, 18% were moderate, and 11% were severe COVID-19 patients. Overall, the most common drugs prescribed were multivitamins, followed by pantoprazole, paracetamol, and azithromycin. Hydroxychloroquine was prescribed in 22%, favipiravir in 7%, and remdesivir in 3% of cases. The majority of moderate COVID patients received injectables piperacillin-tazobactam, methylprednisolone, and enoxaparin. The mean number of medications, duration of admission, and number of days on oxygen were higher and significant in moderate compared to mild and severe COVID patients. Overall, ADRs were encountered in 9% of cases.

Conclusion: The prescribed pattern of drugs was by the national standard guidelines. Multivitamins, followed by pantoprazole, paracetamol, and azithromycin dominated the prescription pattern. Polypharmacy was encountered, which needs to be addressed for the rational use of drugs.

Published: June 2022

Severe migraine attacks often required treatment with specific drugs. The study of pharmaceutical services on the patients with migraine headache has still been limited in Thailand.  This study aimed to investigate the pharmaceutical services offered for a severe migraine patient in the community pharmacies. The study was descriptive research and collected data by using a simulated patient with a severe migraine headache. The fifty-seven community pharmacies, in Phayao province, Thailand, were assessed for the pharmaceutical services. The results demonstrated that the simulated patients received the services from 33 pharmacist-pharmacies (57.89%) and 24 non-pharmacist pharmacies (42.11%). The most frequent dispensed medication was the single drug of pain relievers (n = 30, 52.63%). Non-steroidal anti-inflammatory drug (n = 14, 24.56%), ergotamine (n = 8, 14.04%), and paracetamol (n = 8, 14.04%) were top three most dispensed pain relievers, respectively. Combination therapy between analgesics and other medications was found in 13 pharmacies (22.81%). Domperidone was used as an antinausea drug (n = 8, 14.04%). Prophylactic drugs (n = 6, 10.53%) were flunarizine (n = 35.26%), cinnarizine (n = 2, 3.51%), and amitriptyline (n=1, 1.75%). In conclusion, most pharmacy personnel performed inappropriate practice on taking the necessary information from the patient and drug dispensing for severe migraine. Educational interventions should be developed and trained to improve knowledge and practice in the migraine management.
Association, in an Ant, of a Quantity of an Element with the Time Period of Its Learning
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: June 2022

The workers of the ant Myrmica sabuleti detain numerosity abilities, have a notion of the running time, and can acquire operant conditioning. The present work examines if, according to these skills and through conditioning, the workers of this ant can associate a learned quantity of a given element with the time period of its occurrence. We collectively trained such ants from 8 to 19 o’clock to a stand bearing a given quantity of an element and from 20 o’clock to 7 o’clock next day to a stand bearing another quantity of the same element, and we tested them in front of these two amounts at 16 o’clock and 4 o’clock next day. At 16 o’clock, the ants reacted essentially to the amount presented during training from 8 to 19 o’clock, and at 4 o’clock to the amount presented during training from 20 o’clock to 7 o’clock. They thus associated the learned quantity of an element with the period of the day during which this learning occurred. It may be argued that this association simply results from the three cognitive capabilities cited here above, and does not require any other more complex skill. In addition, the ants appeared to have better learned from 20 to 7 o’clock than from 8 to 19 o’clock, i.e., during the time of day corresponding to their period of highest natural activity.
Investigating the Determinants of the Growth of the New Energy Industry: Using Quantile Regression Approach
Authors: Xu Bin , Boqiang Lin
Published: June 2022

ABSTRACT

Expanding the supplies of new energy can not only reduce CO2 emissions, but also alleviate energy shortage. This paper applies the quantile regression to investigate the new energy industry in China. The results show that economic growth exerts the greatest effect on the new energy industry in the lower 10th quantile province. This is because these provinces have the developed economies, demand for a higher ecological environment and new energy resources. Foreign energy dependence has a minimal impact on the new energy industry in the 25th–50th quantile province, due to their minimal oil importation. The contribution of technological progress to the upper 90th quantile province is the lowest, because their R&D capabilities are the weakest. The impact of energy consumption structure decreases in steps from the lower 10th quantile provinces to the upper 90th quantile provinces. The agricultural sector promotes the new energy industry in most provinces.
Efficiency Measurement in Norwegian Electricity Distribution: A Generalized Four-Way-Error-Component Stochastic Frontier Model
Authors: Tsionas Mike G. , Kumbhakar Subal C.
Published: June 2022

In this paper, we introduce a new model to estimate efficiency by generalizing the state-of-the-art panel stochastic frontier model, the salient feature of which is decomposition of inefficiency into a persistent and a transient component. The proposed model introduces an autoregressive process to allow for temporal dependence in transient inefficiency. Both firm heterogeneity and persistent inefficiency components are allowed to be correlated with some exogenous and endogenous covariates in the model. Our model solves the endogeneity problem and it also introduces determinants of both persistent and transient inefficiency. Since the transient component is autoregressive, the likelihood function is not available in closed form. To address this problem we use the Maximum Simulated Likelihood and (Simulated or Bayes) Generalized Method of Moments method to estimate the parameters and several other quantities of interest, including transient and persistent inefficiency. Since the model is dynamic and accommodates determinants of inefficiency, it is useful to production managers who wish to identify how much of their present inefficiency is affected by past inefficiency, as well as how and in what ways efficiency can be improved. We use Norwegian electricity distribution data to showcase an application of our model.
The Thirst for Power: The Impacts of Water Availability on Electricity Generation in China
Authors: An Yao , Zhang Lin
Published: June 2022

Economic development under restricted resource availability has become a complex challenge for both developing and well-established economies. To maintain a sustainable electricity supply and mitigate the impact of water shortage on economic development, it is therefore important to understand how utility firms respond to the change in water availability and unpacks the underlying mechanisms of power outage. By pairing plant-level information with the fine-scale grid monthly meteorological data, we find significant plant-level technology substitution in response to water scarcity: a one-standard-deviation decrease in water availability causes an approximate 205 GWh decline per hydro power plant, a 145 GWh increase per nuclear plant, and a 28 GWh increase per coal-fired plant. This water-induced technology substitution takes place within the grid, and we do not identify cross-grid adjustment. Our estimation shows that the technology substitution is associated with a hidden increase in carbon emission up to 32000 tons per year by plant, resulting in an additional cost of 0.18 million USD. Water scarcity slows down the transition towards renewable energy.

A presente pesquisa tem como objetivo analisar qual a melhor terapêutica no tratamento da gastroparesia diabética. Para tal, será realizada uma Revisão Sistemática da Literatura utilizando a questão PICO “Em pacientes diagnosticados com gastroparesia diabética, qual o tratamento que apresenta o melhor prognóstico com menos reações adversas?”. A seleção dos artigos será realizada mediante o emprego dos descritores (DeCS) “Gastroparesis” AND “Diabetic” AND “Treatment”, os quais serão inseridos nas bases de dados Biblioteca Virtual em Saúde (BVS) e Medical Publisher (PUBMED), utilizando como critérios de elegibilidade publicações nos últimos cinco anos e apenas Ensaios Clínicos Randomizados, relacionados ao tema proposto. Espera-se que o estudo atual esclareça qual o melhor tratamento para o portador de gastroparesia diabética. Após a leitura dos artigos escolhidos foram identificadas diferentes terapêuticas, que em um primeiro momento se mostraram benéficas em melhorar os sintomas da GD, dentre elas estão a prucaloprida, o felcisetrag e a relamorelina. Foi visto que ainda não há nenhum medicamento totalmente específico para a doença, sendo usado medicamentos que favoreçam um aumento da velocidade do esvaziamento gástrico direta ou indiretamente, que conseguem melhorar os sintomas, por isso, faz-se necessário mais estudos na área para que a fisiopatologia seja elucidada corretamente.
Vulnerability of Primary Productivity and Its Carbon Use Efficiency to Unfavorable Climatic Conditions in Jambi Province, Indonesia

Published: June 2022

Climatic conditions and land cover play crucial roles in influencing the process of carbon uptake through vegetation. This study aimed to analyze the effect of climate variability on carbon uptake of four different land covers in Jambi Province, Indonesia. The four land cover types studied were: forest, shrub, grass, and irrigated soybean, based on Community Land Model version 5. Forest was found to have the highest net primary production (NPP) compared to the other land covers. Seasonal climate variability showed no major effect on NPP and gross primary production (GPP). However, GPP and NPP experienced significant declines during El Niño Southern Oscillation (ENSO), particularly in 2015. Carbon use efficiency (CUE = NPP/GPP) was also affected by ENSO, where CUE decreased during El Niño, particularly in October and November with an increased number of days without rainfall. In addition, the difference between latent (LE) and sensible heat (H) flux, denoted as (LE-H), decreased from August to November. This difference was highly correlated with NPP. This result indicates that when water supply is low, stomata will close, thereby reducing photosynthesis and transpiration, and allocating more of the available energy to sensible heat flux rather than latent heat flux.

La violencia de género contra mujeres en el ámbito de la política (VGcMP) es un fenómeno de reciente visualización. Las investigaciones académicas en torno a este tema han sido mayoritariamente cualitativas. Sin embargo, contar con datos e indicadores precisos de la VGcMP es fundamental para analizar las distintas interacciones y dinámicas de la violencia. El objetivo de este texto es presentar y analizar algunos resultados de la encuesta Experiencias en los procesos electorales 2020-2021, realizada en coordinación entre el CIDE, UNAM y AMCEE. Esta encuesta proporciona datos y resultados con respecto a la VGcMP que sufrieron las mujeres candidatas a presidencias municipales, regidurías y sindicaturas en México durante el proceso electoral 2020-2021.
Provocando el Cambio Cultural: La estrategia comunicacional de las ONG para empujar el Matrimonio Igualitario en Chile
Authors: Álvarez Fuentes Mario , Muñoz Arias Camilo
Published: June 2022

Este artículo analiza cómo los voceros de dos organizaciones de la sociedad civil describen el rol de su estrategia comunicacional para conseguir cambios legislativos. El documento surge de entrevistas narrativas con representantes de las dos principales organizaciones que han empujado la aprobación del matrimonio igualitario en Chile. Los entrevistados cuentan su propia experiencia como voceros del Movilh y la Fundación Iguales y su visión de la relación con los medios de comunicación chilenos. De sus descripciones aparecen tres elementos relevantes de su estrategia. Ambos entrevistados definen a los medios de comunicación como aliados, incluso a los más conservadores. Cuando participaron en los medios, buscaron cambiar el encuadre del problema, mostrándolo como la búsqueda de un matrimonio «igualitario» y no como un matrimonio «homosexual», que era la aproximación predominante. Igualmente desplegaron una táctica para tornar la conversación mediática en un territorio hostil para voces conservadoras y homofóbicas. Ambos entrevistados coinciden en que consiguieron un «cambio cultural» en Chile de tal relevancia que la reforma legal se hizo ineludible.

Published: June 2022

With the growth of access to mobile devices, more applications are emerging for the most diverse purposes. In the health area, applications for monitoring patients with some type of dementia facilitate the day-to-day tasks of both patients and caregivers. However, a remaining challenge is to maintain patient loyalty in using the application so that their data can be constantly collected and analyzed, and treatments and follow-ups can be effective. One approach to trying to improve this situation is to customize and adapt the system, bringing it closer to the preferences of each user. This paper presents the conceptual approach and a prototype of a mobile self-monitoring system for patients with Mild Cognitive Impairment (MCI), a pre-dementia condition, which aims to maintain user loyalty in using the system.

O aumento na quantidade de dispositivos móveis vendidos levou ao surgimento de inúmeros exemplares de malware para estas plataformas. Essa situação é especialmente grave no caso do sistema Android, cujas lojas (oficial e alternativas) servem como ponto de infecção para muitos usuários. Com isso, faz-se necessário o desenvolvimento de técnicas para analisar aplicações provenientes das lojas de Android e identificar seus comportamentos maliciosos antes que elas sejam obtidas por usuários. Neste trabalho, apresenta-se um ambiente para análise dinâmica e detecção por aprendizado de máquina de malware de Android. Os testes para validação do ambiente, realizados com milhares de aplicações, resultaram em uma taxa de detecção de 95,45%.
O estado da arte da legislação brasileira sobre a criminalidade cibernética
Authors: Valverde Danielle Novaes de Siqueira , Silva José de Siqueira
Published: June 2022

Este artigo apresenta um estudo sobre os tipos penais e as normas processuais penais brasileiras relativas ao crime cibernético, sob o enfoque da classificação oferecida pela International Telecommunication Union. A primeira conduta relacionada à informática a ser criminalmente tipificada foi a pirataria de software, no ano de 1987, por força de Lei nº 7.646. O combate à pornografia infantil ganhou maior efetividade com a edição das Leis nº 10.764, de 2003 e n° 11.829, de 2008. Mais recentemente, a Lei nº 12.737, de 2012 tipificou criminalmente os primeiros delitos puramente informáticos. O processo penal ainda carece de normas que ofereçam à investigação e à perícia forense mecanismos que facilitem a construção probatória e a identificação do autor do delito.

Authors: Melo Jr. Wilson S. , Prado Charles B. , Carmo Luiz F. R. C.
Published: June 2022

A autenticação de sensores é um desafio que necessita ser tratado de forma apropriada. Neste artigo é proposto o uso de eventos físicos para autenticação de sensores. A imprevisibilidade e unicidade dos sistemas físicos são exploradas para gerar identificadores de evento a partir de dados de sensoriamento. Sendo únicos e difíceis de se deduzir, identificadores de evento podem ser usados para reforçar a autenticação. Além disso, eles proveem evidências de co-alocação e simultaneidade da autenticação, evitando ataques do tipo relay e replay. A viabilidade dessa proposta é demonstrada em sistemas de instrumentação de testes de impacto veiculares, com resultados promissores.

Published: June 2022

Programas maliciosos têm evoluído em sofisticação e complexidade, aumentando a incidência de ataques bem sucedidos contra sistemas computacionais e seus usuários. Como qualquer programa benigno, os programas maliciosos precisam interagir com o sistema operacional de forma a realizar as atividades pretendidas. Assim, faz-se necessário compreender quais das ações efetuadas estão envolvidas em processos de infecção. Tais ações "suspeitas" compõem o comportamento de execução do malware e sua identificação é crucial na detecção desses programas. Neste artigo, propõe-se uma metodologia para detecção de malware baseada em heurísticas comportamentais e apresenta-se os testes e resultados obtidos de sua aplicação em exemplares reais.

Published: June 2022

Atualmente os mecanismos de segurança utilizados para detecção de intrusão em ambientes de automação industrial utilizam dados exclusivos TIC (Tecnologia da Informação e Comunicação) ou TO (Tecnologia da Operação). Este trabalho propõe um IDS (Intrusion Detection System) que integra informações TIC e TO para identificação das cadeias de eventos TIC e TO que ocasionaram a falha no processo industrial. Medições demonstram que o tempo de resposta e a taxa de acerto são linearmente proporcionais ao volume de dados processados permitindo um planejamento prévio da arquitetura ao ambiente de trabalho.
A framework for searching encrypted databases
Authors: Alves Pedro Geraldo M. R. , Aranha Diego F.
Published: June 2022

Cloud computing is a ubiquitous paradigm. It has been responsible for a fundamental change in the way distributed computing is performed. The possibility to outsource the installation, maintenance and scalability of servers, added to competitive prices, makes this platform highly attractive to the industry. Despite this, privacy guarantees are still insufficient for data processed in the cloud, since the data owner has no real control over the processing hardware. This work proposes a framework for database encryption that preserves data secrecy on an untrusted environment and retains searching and updating capabilities. It employs order-revealing encryption to provide selection with time complexity in Θ(log n), and homomorphic encryption to enable computation over ciphertexts. When compared to the current state of the art, our approach provides higher security and flexibility. A proof-of-concept implementation on top of MongoDB is offered and presents an 11-factor overhead for a selection query over an encrypted database.

Published: June 2022

A criptografia completamente homomórfica, uma das áreas da criptografia pós-quântica, é uma das técnicas para o processamento e manipulação de dados criptografados sem decifrá-los. Utilizada em plataformas onde a criptografia tradicional pode não ter a segurança desejada, como o caso da computação em nuvem. Diversos métodos têm sido propostos para viabilizar o uso dessa técnica. Porém, para a sua efetiva utilização, há a necessidade da geração de parâmetros que resultam em chaves com tamanhos extremamente grandes. Este artigo tem como objetivo reduzir o tamanho das chaves públicas usando o algoritmo de otimização por colônia de formigas para ratificação da calibração das variantes de algoritmos já presentes na literatura.

Published: June 2022

A análise dinâmica é uma das principais técnicas utilizadas para caracterização de malware, identificação de suas funcionalidades e desenvolvimento de contra-medidas. Portanto, desenvolvedores de malware buscam continuamente por formas de impedir a execução de seus códigos nesses ambientes, dificultando a detecção. Além disso, avanços nos sistemas operacionais criaram obstáculos para sua instrumentação. Para superar tais problemas, surgiram abordagens de análise assistidas por hardware. Neste artigo, propõe-se um sistema de análise dinâmica de malware baseado em monitoramento de branches com suporte de hardware (monitores dos processadores Intel), alcançando a transparência necessária para evitar a identificação do ambiente e apresentando baixo overhead.
