Published: March 2022

O objetivo deste estudo foi analisar a associação da exposição à poluição atmosférica e as internações hospitalares por doenças respiratórias (CID‑10: J00-J99) de residentes em Volta Redonda (RJ), no período de 2013 a 2015, bem como estimar seus custos. Foram considerados dados do Instituto Estadual do Ambiente (INEA) para partículas totais em suspensão (PTS), PM10 e ozônio (O3) e dados disponíveis no DATASUS referentes à morbidade por doenças respiratórias por faixa etária (total, crianças e idosos). Para estimar tal associação, foi utilizado o modelo aditivo generalizado de regressão de Poisson. Observou-sea elevação do risco de admissão hospitalar para a elevação de 10 μg/m3 de PM10 para o total de internações — lag 2: 1,39% (IC95% 0,23–2,55%) e lag 3 1,36% (IC95% 0,21–2,52%) — e para os idosos — lag 3: 1,89% (IC95% 0,02–3,69%) e lag 4 1,9% (IC95% 0,02–3,85%) —, de PTS para o total de internações — lag 2 0,84% (IC95% 0,40–1,64%) — e para crianças menores que 5 anos (lag 4: 2,2% (IC95% 0,05–4,02%) — e de O3 para os idosos (lag 6: 2,41% (IC95% 0,31–4,57%). Destaca‑se que as associações ocorreram mesmo quando os níveis de poluentes não ultrapassaram os limites estabelecidos pela legislação. Do total de internaçõespara o período, 99 foram atribuídas à exposição ao PM10, gerando custo de R$ 115.165,25 para o Sistema Único de Saúde. Espera-se que essas informações contribuam para a discussão da problemática ambiental na região.
Replacement Method of Main Parts of Mining and Earth Moving Equipment: Current Situation and Prospect of Machinery Industry
Authors:   Zambia, Galatia Dyson
Published: March 2022

The dynamic production budgets and the volatile metal prices in the current mining industry have stimulated and strengthened a continuous search for operating efficiency in all areas of the production process, with reliability of the earth moving equipment being one of the core aspects. Unpredicted breakdown of earth moving machine major components usually cause serious consequences such as loss of production, extra cost and deviation from mine plans. From a financial perspective, these components are one of the key cost drivers among the top Mine cost centers and success in managing them (achieving expected life cycle and operational cost) is essential in meeting maintenance and production cost (cost/ton) of the equipment. Whereas relatively small and frequent repairs largely affect availability, operational cost is directly affected by major component failure. In trying to maximize the operating efficiency of earth moving equipment, various maintenance strategies and methodologies have been tried, tested and initiated. However, the challenge in most, if not all operations, has been to find an accurate method to determine the exact expected replacement point of major components. This phenomenon has been challenging, though a number of operations engage in a time-based replaced strategy as recommended by most equipment manufacturers, replacement schedules are rarely executed as panned. The norm however, has been to draw up a calendar of parts to be replaced each year during budgeting time and scheduled intervals of replacement are set following the Original Equipment Manufacturers’ (OEM) recommendation. Nevertheless, these schedules have not conclusively determined the point at which the replacement is economically justified. This study therefore, highlights the challenges of the traditional time-based component replacement strategy and recommends an approachbased on condition assessment.The data used in this study are obtained from different Mines as well as the experience of the researcher(ethnological study in the industry). The study concludes that, to realize optimum utility from a component, a component management strategy must start right from equipment selection and purchase decisions. Thus, criticalcomponents, which require preventive replacement, need to be identified and monitored through condition monitoring. Condition inspections must bescheduled in such a way that they do not adversely affect the availability of the equipment.

Loss of teeth affects both an individual's appearance and functioning, with a negative impact on psychological and social wellbeing. Implant-supported prosthesis has proven advantages like increased masticatory efficiency, maintenance of the bone, improved function, phonetics, aesthetics, etc. There is a variation in the level of awareness about dental implant treatment among people. As NSS volunteers are mostly involved in creating awareness about several aspects among the population, there is a requirement of assessment of their knowledge about dental implants to improve the efforts to be taken to upgrade their awareness about the same. The aim of this study was to assess the awareness of dental implants among NSS volunteers of Bhubaneswar city, Odisha State, India using a questionnaire survey. A questionnaire survey was conducted among 1500 NSS volunteers of Bhubaneswar city, Odisha State, India through a printed questionnaire comprising of 12 close-ended questions to evaluatethe awareness of dental implant treatment between Dec-Jan 2019-20.Statistical analysis was done using SPSS 23 software. Among 1500 subjects, a total of 587(39.1%) population was aware of dental implant treatment, 1270 (84.7%) believed that high cost and lack of knowledge was a limitation for implant treatment, 1189 (79.3%) felt that dental implants had better longevity.

Published: March 2022

Communication, behavioral and attitudinal skills are an integral part of teaching behavior management to dental undergraduate students. Due to the complexity of these skills, clinical teaching through didactic method imparts minimal capacity for adopting deep approach to learning. The implication of role play and group discussion could be an opportunity to facilitate such learning outcome. The objectives of this study were to evaluate and compare the efficacy of role play and group discussion as teaching-learning methods for behavior management in pediatric dentistry. The study was carried out with ninety-two final BDS undergraduate students at Sharad Pawar Dental College & Hospital, INDIA. Tell-Show-Do, non-pharmacological behavior management technique was taught to intervention and control group by role play and group discussion method respectively. To assess knowledge gain, pre-test and post-test was conducted. To evaluate acquisition of communication, behavioral and attitudinal skills, students were made to perform a clinical procedure i.e. placement of pit and fissure sealant in primary molars. Each student was evaluated by direct observation using a check-list.  Role play method was found to be highly effective as significant difference was observed in knowledge gain (p=0.020) and acquisition of behavioral and attitudinal skills (p= 0.027) among intervention and control group.

The aim of this study evaluate the salivary alkaline phosphatase levels in tobacco users to determine its role as a biomarker in oral potentially malignant disorders. This prospective observational study comprised 60 individuals aged between 18 and 70 years who were categorized into four   groups. For Group II, Group III and Group IV, individuals with the habit of smoking/tobacco chewing for a minimum period of 6 months were included in this study.  The mean values for S‑ALP were found to be about 19.00 IU/L (SD 12.37) for Group I (range from 7 to 50 IU/L), 8.50 IU/L (SD 3.35) for Group II (range from 2 to 14 IU/L), 5.60 IU/L (SD 1.01) for Group III (range from 1 to 8 IU/L) and 65.90 IU/L (SD 50.70) for Group IV (range from 10 to 146 IU/L). Comparison of S‑ALP between the groups showed a statistically significant difference (P < 0.001) using Kruskal–Wallis’ ANOVA. To know if there is any difference in S‑ALP levels between tobacco users and nonusers (Groups I and II and Groups I and III) and among the different forms of tobacco users (Groups II and III), the mean S‑ALP levels were compared using Mann–Whitney U‑test.

Knowledge Gaps in Curricular Guidance for ICS Security
Authors: Ngambeki Ida , McBride Sean , Slay Jill
Published: March 2022

Industrial Control Systems are an essential mechanism to manage complex computer systems necessary for modern life. These include everything from water treatment and transportation to energy systems and manufacturing. These systems are becoming increasingly integrated and more complex, and they are being used to manage even more of the elements that make our everyday lives possible. They are therefore becoming both more attractive to cyber criminals and more vulnerable to cyber-attacks. More attention needs to be paid to increasing resources and capability in industrial cybersecurity (ICSS). A major element of this is to significantly improve both the quality and availability of education in this area. The process of development of these educational initiatives is aided by curriculum guidance documents. Of necessity ICSS has largely evolved in industrial settings. This exploratory study examines the curricular guidance available for ICSS research and compares it to industry requirements to identify gaps in curricular guidance. Specifically, this paper looks at the three leading guiding documents, the NICE Cybersecurity Workforce Framework, the Joint Task Force on Cybersecurity Education curriculum guidance, and the NSA CAE knowledge units. These are then compared to requirements identified from ICSS related job postings. We found that the primary cybersecurity curriculum guidance documents do not sufficiently address industry requirements for ICSS.

This work presents LUCID Network Monitoring and Visualization Application (LNMVA), a comprehensive visualization software application for cyber security visualization. The application consists of five component types: components for monitoring network traffic, components for reporting various network messages, data storage components plus a visualization component and an automated animation reporting component. LNMVA can serve as an aid in teaching complex concepts in cybersecurity or to visually demonstrate active security events on a network to an audience or participants in the classroom or cyber defense competitions at near real-time speed. Its flexibility enables it to visualize different kinds of cybersecurity concepts, protocols and ideas. LNMVA is a sub-system of LUCID, a visualization and broadcasting system that aims to improve understanding and sense-making to participants or an audience. The system is targeted to intermediary or expert users engaged in cyber security exercises. Preliminary results from subject testing show that LNMVA with embodied virtual commentator provided an engaging environment to improve participants’ understanding and sense-making in active security events.
Using Complexity Theory to Identify K-12+ Pedagogical Misalignment With a Security Mindset
Authors: Hanna Holly , Blanken-Webb Jane
Published: March 2022

The current state of growing connectivity in society calls for a security mindset for K-12 and post-secondary (K-12+) populations. A security mindset offers an important approach to support security and can usefully be understood through the lens of complexity theory. Complexity theory also provides a helpful lens for identifying limitations inherent within some common pedagogical frameworks and practices in K-12+ education systems that may pose challenges for the cultivation of a security mindset. Hence, this paper brings awareness to examples of some of the most prominent pedagogical frameworks and practices that stand in potential misalignment with a security mindset when they are implemented in an imposing, monolithic manner. These include: rigid, prescriptive curricula; binary thinking, compliance, and standardized assessments; and disciplinary constraints. By identifying ways that common pedagogical practices stand to potentially undermine the cultivation of a security mindset, this paper contributes to clearing the way forward for K-12+ educational systems to design for emergence in support of building a more secure society.
Ginés Andrés de Aguirre (1727-1800). Un pintor entre España y América
Authors: López Ortega Jesús
Published: March 2022

A día de hoy, la figura de Ginés Andrés de Aguirre carece de un exhaustivo estudio monográfico que abarque de forma completa toda su trayectoria artística. Han pasado más de cuarenta años desde que José Luis Morales y Marín publicase el único trabajo en conjunto que se conoce sobre el pintor. Desde entonces, las investigaciones que se le han dedicado han sido parciales y, a excepción de unas pocas, apenas se han ocupado de aspectos cruciales de su carrera. Este trabajo intenta, con los límites impuestos, paliar en gran medida esta falta. Con un importante acopio de material de archivo inédito y el estudio e interpretación de documentos, fuentes y publicaciones, se abordan las dos etapas cruciales en las que ha quedado constituido su periplo vital: España y México; recogiendo una gran parte de sus obras documentadas e incorporando otras, que se han podido ir sumando a su catálogo.

O relato de experiência do evento ‘’I Simpósio sobre doenças tropicais negligenciadas’’ tem como objetivo demonstrar o silogismo utilizado durante o projeto, através do contexto sobre a atual situação de saúde pública no Brasil. Durante o simpósio foram descritas doenças tropicais que, ainda que possuam incidência significativa, são comumente negligenciadas. Outrossim, correlacionou essas enfermidades com a pandemia de Covid-19 e com questões sociais, físicas e mentais envolvidas nesse tema, visto que é de extrema importância o conhecimento dessa situação pelos médicos e acadêmicos brasileiros. O evento ocorreu nos dias 19 a 21 de abril de 2021, e foi realizado online através da plataforma StreamYard com transmissão simultânea via Youtube, na qual os espectadores puderam tirar dúvidas pelo chat. As doenças abordadas foram hanseníase, oncocercose, esquistossomose, leishmaniose, micetoma e doença de Chagas. Ao final de cada palestra, os participantes responderam um questionário, via Google Formulários, o qual foi comparado com outro formulário de pré-evento para avaliação de impacto do simpósio.   
A correlação com a Covid-19 é de extrema importância para a formação médica atual, tendo em vista seus impactos econômicos, sociais, culturais e políticos, sendo essencial que, conjuntamente a esse cenário, sejam desenvolvidas estratégias que atendam às necessidades de saúde de populações vulneráveis em nosso país. Ademais, os desafios envolvendo este grupo de enfermidades são grandes, pois são múltiplos os fatores que tornam o diagnóstico e tratamento das doenças tropicais negligenciadas um entrave para o sistema de saúde brasileiro. Portanto, o evento ‘’ I Simpósio sobre doenças tropicais negligenciadas’’ além de mostrar-se um espaço de aprendizado para a formação acadêmica e pessoal dos estudantes, torna-se uma ferramenta para a aplicação de ações futuras em relação ao manejo e prevenção dessas enfermidades no Brasil.

Introduction. Epilepsy is one of the most common chronic nervous system disorders. Epilepsy in a child requiring physical, psychological and speech therapy significantly reduces its scope and decreases the likelihood of recovery.
The aim of the study was to assess the efficacy and safety of a rehabilitation programme for young children with movement disorders and concomitant epilepsy.
Materials and methods. Simple randomization was used to divide 123 children aged 924 months into four groups: three main groups and one comparison group. Patients in group 1 received traditional massage, excluding the cervical region, as their rehabilitation. Patients in group 2 received kinesiotherapy (Vojta therapy) in addition to traditional massage. Children in group 3 participated in a comprehensive programme, including traditional massage and kinesiotherapy (Vojta therapy). Children in the control group did not receive rehabilitation.
Results. A statistically significant improvement in the psychomotor development parameters was observed after a course of medical rehabilitation. It was more significant when the epileptic focus was localized in the right hemisphere or the patient had generalized epilepsy. The outcome was less favourable in multifocal epilepsy and when the epileptic focus was present on the convex surface of the left hemisphere. The third group noted a statistically significant improvement in the GMFCS scores by the end of the comprehensive rehabilitation course. There were no epileptic seizures seen on repeat EEG recordings during the medical rehabilitation and one month after its completion.
Conclusion. A comprehensive approach to planning a course of rehabilitation ensures its efficacy. The location of the epileptic focus and the distribution of epileptic activity along the convex surface of the brain determines the outcome of medical rehabilitation. An increased epileptiform activity index on EEG without signs of clinical deterioration requires more careful patient monitoring but, nevertheless, is not a reason to completely cancel rehabilitation measures.

Accuracy of the Electrocardiogram in Identifying Chronic Heart Failure due to Left Ventricular Systolic Dysfunction
Authors: Altalhi Hanan G. K , Abdalgbar Asgad  A
Published: March 2022

There is a common assumption that a normal electrocardiography rules out chronic heart failure due to left ventricular systolic dysfunction (LVSD). In this research work, an assessment of the value of electrocardiography in identifying patients with chronic heart failure due to LVSD was investigated.

Patients admitted to Al-Bayda central hospital with suspicion of heart failure for clinical assessment and electrocardiography, echocardiography; the accuracy of each screening tests were calculated for left ventricular systolic dysfunction and heart failure. A total of 120 patients' aged between 36-100 years was assessed; 22 patients had impaired left ventricular systolic function, among them 21 patients had major electrocardiography abnormalities (Left bundle branch block, pathological Q wave, Left ventricular hypertrophy, poor R wave prog-ression, Ischemic ST-T changes, Left anterior fascicular block, IV conduction defect). Out of 98 patients with normal left ventricular systolic function, 38 had major electrocardiography abnormalities. In conclusion, the study showed that left ventricular systolic dysfunction is un likely to be present if the electrocardiography is normal (or shows only minor abnormalities); conversely, there is usually a major electrocardiographic abnormality in the presence of left ventricular systolic dysfunction.

The objective of the present work is to study the effect of machining parameters on the straightness error of cylindrical parts of high carbon steel (SAE 1095) having hardness 210 BH produced in a lathe machine. The considered turning parameters that affect the straightness error are cutting speed ,feed rate and depth of cut at three levels for each parameter with two replicates of different length by diameter ratio for instance there are 3x3x3x2= 54 specimens to be  machined. The straightness error are measured for each specimen and statistical analysis are carried out .The analysis of variance performed on the measured data shows that the cutting speed is the most significant factor affecting  straightness error, secondly  the feed rate and lastly the depth of cut. Also, the interaction cutting speed-depth of cut  and cutting speed-feed rate-depth of cut  affect the straightness error of the machined work piece too. The present work is provided with three dimensional surface graphs which show low straightness error at high cutting speed for each considered level of  feed rate and depth of cut.

Published: March 2022

Tobacco smoking use is widely spread throughout the world. Tobacco smoking has been claimed to cause a wide variety of health problems such as atherosclerosis, mutagenesis of exposed cells and cancer. The effects of smoking on human health are serious and in many cases, deadly. The present study was done to investigate the effect of cigarette smoking on some hematological parameters in male smokers. The study is carried out on thirty Libyan male smokers, who smoked at least 10 cigarettes per day for at least15 years. Their age ranged between 30-60 years. Control (non-smokers) group was collected with the same range of age for statistical comparison. The results of the study revealed a significant increase of hematological parameters (Hb: Hemoglobin; PCV: Packed cells volume; RBC: Red blood cell and WBC: White blood cell) in smoker group when compared with the control. No significant difference of the platelet count was recorded in smoker group when compared with control. Furthermore the level of malondialdehyde (MDA), which is an indicator of lipid peroxidation and oxidative stress significantly increased in cigarette smokers group when compared with control group. To conclude, cigarette smoking leads to oxidative stress by free radical generation (Reactive oxygen species-ROS) by the mechanism of lipid peroxidation. Smoking exerts negative influence on the hematological parameters and these are the contributing factors that lead to cardiovascular and atherosclerosis that usually occur in cigarette smokers and cause of death.

أجريت هذه التجربة على عقل غضة وعقل خشبية لأربعة أنواع من نباتات الزينة هي: الهيبسكس واللانتانا (عقل خشبية) والمرجريتا والشيرانيا (عقل غضة) وبعد حوالي أسبوعين من زراعة العقل لوحظت براعم ورقية جديدة على بعض العقل من نباتات الشيرانيا والمرجريتا والهيبسكس واللانتانا مما يدل على نجاح عملية التجذير وبعد مضي 45 يوماً من الزراعة تم إزالة جميع العقل من بيئة الزراعة وتم عد وقياس أطوال الجذور في كل عقلة. وجد أن عدد الجذور وطولها في نبات الشيرانيا كان أكثر بدون إستخدام هرمون التجذير (NAA) منه في حالة استخدام التركيز الموصى به (0.4% w/w) أو نصف التركيز (0.2% w/w) حيث كان عدد الجذور في معاملة الشاهد يفوق معاملة 50% من تركيز الهرمون بمقدار أكثر من ستة أضعاف ويفوق معاملة التركيز الكامل للهرمون بمقدار تسعة أضعاف. أما بالنسبة لطول الجذور فلقد بلغت معاملة الشاهد 13 ضعف لمعاملة 50% من تركيز الهرمون و 39 ضعف معاملة التركيز الكامل للهرمون. وبالنسبة لنبات المرجريتا فقد أظهر إستجابة واضحة فيما يتعلق بتنشيط التجذير بواسطة الهرمون، حيث تفوقت معاملات 50%، 100% من تركيز الهرمون على معاملة الشاهد (بدون هرمون)، فقد تضاعف عدد الجذور في معاملة 50% من تركيز الهرمون بأكثر من ثلاثة أضعاف الشاهد وتضاعف عدد الجذور بمقدار 19 مرة في معاملة التركيز الموصى به للهرمون عن معاملة الشاهد، كما لوحظ أيضا أن أطوال الجذور بلغ في حالة نصف تركيز الهرمون مرتين معاملة الشاهد وحوالي 13 مرة في حالة التركيز الكامل للهرمون. وفي نباتي الهيبسكس واللانتانا حيث أستخدمت فيهما العقل الخشبية كانت أعداد وأطوال الجذور فيهما قليلة جداً مقارنة بنباتي الشيرانيا والمرجريتا اللذان استخدم فيهما العقل الغضة. أظهرت عقل الهيبسكس إستجابة ضعيفة لتركيزات الهرمون وبدون فروقات معنوية واضحة فيما يتعلق بأطوال الجذور بينما لم تظهر معاملة الكنترول أي استجابة، وفي حالة عقل اللانتانا كانت معاملات الهرمون أقل من إستخدام العقل بدون هرمون على طول الجذور وبدون أي فروق معنوية بينها.
Monitoring land use /land cover using multi-temporal Landsat images in Al-Jabal Al-Akhdar area in Libya between 1984 and 2003
Authors: Masoud Moussa
Published: March 2022

This study investigated the change in land cover of Al-Jabal Al-Akhdar from 1984 to 2003 by using satellite images. Four categories of land-cover (forest, rangeland, urban area and desert) were studied to determine the change between 1984 and 2003. Supervised classifications were performed on the Landsat 5 images. The land resources database showed that the rangeland and forest recorded negative change over the years under study while it was a significant positive change in the urban areas. The most significant change was the desert expanding. Rangeland surface proportions were 43.34% in 1984 but were decreased to 28.63% in 2003. Forest surface proportions were 22.13% in 1984 but were decreased to 10.17% in 2003. This can be attributed to human activities, which includes over- grazing, indiscriminate bush burning, fire and urban areas. This is a clear indication of an increase in population and infrastructure development in the study area, regardless of use or pattern. Information from satellite remote sensing can play a useful role in understanding the nature of land use and land cover changes (LULCC), where they are occurring, and projecting possible or likely future changes.
Survival and metabolic characteristics of Lux-Marked Escherichia coli O157:H7 in different types of milk
Authors: Lahmer Rabya A. , Jones Davey L. , Williams Prysor
Published: March 2022

Escherichia coli O157:H7 is a potentially lethal pathogen which has been responsible for several outbreaks of milk-borne illness in recent years. The objective of this study was to evaluate the survival and metabolic activity (indexed by bioluminescence) of a chromosomally lux-marked strain of E. coli O157:H7 in raw, pasteurized and microfiltered pasteurized milk at 4 and 20°C for up to 14 d. Results showed that the population of E. coli O157:H7 and its metabolic activity decreased in all samples during storage at 4°C, with no significant differences in numbers observed between the different milk types; but the metabolic activity was significantly higher (P<0.05) in the microfiltered pasteurized milk than that in raw milk. At 20°C, E. coli O157:H7 counts and cell activity peaked at day 2, and then declined progressively. At 20°C, survival and metabolic activity were significantly lower in raw milk compared with pasteurized milk. We conclude that storage temperature is more important in regulating the survival of E. coli O157:H7 in contaminated milk than its origin/pre–treatment conditions.

Published: March 2022

Congenital heart diseases (CHD) are one of the most frequent malformations at birth. The aims of this study were to assess the prevalence of congenital heart disease, their different types, and their detection rate among children in Aljabal Alakhdar, Eastern part of Libya. The study was conducted during three-year period (September 2009- October 2012). The prevalence of CHD in Althawra Hospital Albaida was studied. The diagnosis of structural defects was based on echocardiographic study. Age groups from neonates till adolescent were included.In the study period, 342 children were found to have CHD; 299 patients were neonates and infants. Total prevalence of CHD over the study period was 8.9 per 1,000 live-born. The prevalence increased from 8.6 to 9.2 per 1,000 live births between 2009 and 2012. Isolated ventricular septal defect (34 %) was the most frequent non cyanotic anomaly, and Tetralogy of Fallot (3.5 %) was the most frequent cyanotic anomaly.The Prevalence rate of CHD in this region compare to the international standard is almost similar. Increasing incidence of CHD might be attributed to easier diagnosis with more regular and fixed dates of pediatrics cardiac clinic in the hospital in last few years or it may indicate a real increase in the defects, which might need further studies to know the possible causes.

Published: March 2022

PCOS(Poly Cystic Ovarian Syndrome) is a hormonal disorder that affects women during their reproductive years (18-30year ).It is a condition that affects ovulation and the ovaries.Many fluid-filled sacs develop inside the ovaries in PCOS.These are follicles,each of which contains an immature egg.The egg is never mature enough to cause ovulation to occur. Important alterations in ovarian vascularization at the level of introvarian arteries occur in PCOS patients. Objective: Is colour Doppler ultrasonography is helpful in evaluation of PCOS. Method: An electronic database search with data range from 1999-2021 was performed(Science Direct, Google Scholar, PubMed, Springer).28 articles were found.All studies fully available evaluating PCOS ondoppler ultrasound. Results: Performance of Doppler ultrasound diagnosis was evaluated. PCOS patients had decreased ovarian artery pulsatility index (PI), resistance index (RI), and SD ratios and increased uterine artery pulsatility index (PI), resistance index (RI), and SD ratios. Conclusion: It is concluded that lowest ovarian stromal resistance levels were found in the patients than the controls.
