Authors: Vineeth Nandhini , Guruprasad H. S. , Sheetal V. A.
Published: November 2021

Imparting quality technical education and training can be expected to be the vision of most engineering institutions globally to build a healthy society. The major stakeholders who contribute to this are students, teachers, industrialists, researchers, and institutes. The current scenario of rapid technological advancements demands engineering students to be dynamic and novel. Considering the heterogeneous intellectual ability of students, institutions frame time-restricted curriculums. Students who want to outperform have a challenge that they cannot be completely dependent on their academic curriculum. The objective of this chapter is to motivate and bring awareness among engineering students to adapt self-learning to excel in their professions. E-learning and project-based learning are identified as the two significant tools that could help students to self-learn. The influence of these tools on engineering students has been proved in this chapter with a case study, surveys, and feedback from students.

Authors: Supekar Bhagyashree B. , Wankhade Vaishali H. , Singh Rajesh P. , Ghanate Tejal D. , Bhat Dharitri
Published: November 2021

Introduction:

Extrapulmonary tuberculosis (EPTB) is a significant health problem in both developing and developed countries. In India, cutaneous TB constitutes about 0.1% to 2% of the total skin diseases attending outpatients.

Aim and objectives:

To study the clinical spectrum and therapeutic outcome in cutaneous TB.

Material and Methods:

Medical records of diagnosed cases of cutaneous TB from June 2015 to June 2018 were analyzed retrospectively with respect to epidemiology, clinical features, investigations, and treatment outcome. Statistical analysis was done using mean, median, and proportion.

Results:

Fifty-two patients with cutaneous TB were recruited. Females (61.53%) outnumbered males. The most common age group affected was 21–30 years (32.69%) followed by 41–50 years (30%). Lupus vulgaris was the most common clinical type with head and neck being the most common site of involvement. Mantoux positivity was reported in 67.30% of patients while raised ESR in 71.15% of patients. Two patients had serology positive for HIV. Conclusive evidence of TB on histopathology was reported in 86.53%. Excellent response was observed in cases of lupus vulgaris, scrofuloderma, and tuberculosis verrucosa cutis.

Conclusion:

This retrospective analysis emphasizes the importance of clinicopathological correlation and therapeutic response in cutaneous TB. Although positive results of ESR, Mantoux reactivity, and TB cultures facilitate the clinical diagnosis, negative results should not exclude the diagnosis of cutaneous TB. This prominent case detection in the era of the Revised National TB Control Programme, in short period of time signifies health burden of cutaneous TB in this part of Maharashtra.

Published: November 2021

Background:

There has been an upsurge in the cases of cutaneous leishmaniasis over the past few years in the pediatric population of Jammu and Kashmir, hitherto a nonendemic area for the disease., The aim of this study was to describe the clinico-epidemiological profile and therapeutic outcome of pediatric cutaneous leishmaniasis (PCL) over a 10-year period in J and K.

Materials and Methods:

An observational study was conducted at two tertiary care hospitals of Jammu and Kashmir over a period of 10 years (July 2010–June 20). Children presenting to the outpatient department with lesions suggestive of CL were enrolled. Patients suspected of having CL based on clinical criteria were subjected to slit skin smears (SSS) and histopathological examination (HPE) for validation of the diagnosis. Intralesional or systemic sodium stibogluconate (SSG) was the treatment modality used for the management of patients. Clinical follow-up was done at intervals of 2 weeks for the first 2 months and monthly thereafter.

Results:

A total of 376 cases of CL in children aged 1.5–15 years (mean age 8.4 ± 1.4 years) were included in the study. The duration of the disease ranged from 8 to 52 weeks (mean 22.52 ± 1.5 weeks). Lesions were noted mainly on exposed parts of the body, with face being the most commonly affected site (89.0%). Nodulo-ulcerative plaques were the predominant clinical presentation (62.76%). The diagnosis was confirmed by the demonstration of Leishman Donovan (LD) bodies in 54.25% on SSS- and 25.79% on hematoxylin and eosin -stained tissue sections. In cases where diagnosis could not be confirmed by demonstration of LD body, a histological pattern conforming to CL and response to a therapeutic trial of SSG provided evidence of leishmanial infection. Complete healing was achieved in 95.02% of the cases at the end of treatment.

Conclusion:

CL is an emerging health problem in the pediatric population of Jammu and Kashmir. Awareness among pediatric health workers regarding this disease and recognition among the differential diagnosis of ulcerated papules or plaques in the pediatric population is imperative.

Authors: Kowe Priyanka A. , Bhushan Ravi , Wankhade Vaishali H. , Singh Rajesh P.
Published: November 2021

Chronic acral hyperkeratotic dermatosis includes several conditions such as lichen simplex chronicus (LSC), hypertrophic lichen planus (HLP), psoriasis vulgaris (Ps), acral acanthosis nigricans, acquired zinc deficiency, and necrolytic acral erythema (NAE). LSC, Ps, and HLP respond to conventional treatments such as topical corticosteroids, immuno-modulators such as tacrolimus, and oral methotrexate. Zinc-responsive acral hyperkeratosis is a novel entity that resembles the above mentioned diagnoses clinically but fails to respond to the above treatment options. NAE is a rare condition, commonly associated with hepatitis C virus infection and manifest similar clinical features of zinc-responsive acral hyperkeratosis, but differs histopathologically. Both conditions show a good response to oral zinc supplementation. As there is a paucity of literature on zinc-responsive acral hyperkeratosis, we are highlighting the case.
Evaluation of the Efficacy of Intralesional Measles, Mumps, and Rubella Vaccine with Intralesional Vitamin D3 as Immunotherapies in the Treatment of Recalcitrant Cutaneous Warts in Adult- A Randomized Placebo-Controlled Study
Authors: Mohta Alpana , Kushwaha Ramesh K. , Agrawal Aditi , Sharma Manoj K. , Gautam Umesh , Jain Suresh K.
Published: November 2021

Introduction:

Currently, various destructive and ablative treatment options are conventionally used for warts, but all of them are limited in some form by their adverse effects, high recurrences, suboptimal effectiveness, and the need to treat every wart. Lately, immunotherapy has emerged as a safe treatment relying on biological substances that modulate the immune system to achieve disease control.

Aims and Objectives:

We aimed at conducting a placebo-controlled study to compare the rate of efficacy of intralesional MMR vaccine with vitamin D3 in the management of recalcitrant extragenital warts in immune-competent adults. Follow-up was done at third and sixth month.

Materials and Methods:

Patients were divided into three groups, namely, group A, B, and C. Groups A, B, and C received intralesional MMR vaccine, vitamin D3 and normal saline, respectively, in the largest wart. The injections were repeated every 2 weeks, for a maximum of four injections.

Results:

Among injected warts, in group A, complete clearance was seen in 29 (87.8%) patients, partial clearance in two (6.1%) and no response in two (6.1%) patients. In group B, 24 (77.4%) patients, five (16.1%) patients, and two (6.5%) patients showed signs of complete, partial, and no clearance, respectively, in injected warts. Complete response in distant warts was seen in 25 (75.7%) patients in group A and 20 (64.5%) patients in group B. There was no statistically significant difference between responses of the two groups. In group C, only three (12.5%) patients had complete clearance in injected warts, and none in distant warts. Recurrence was seen in two (6.4%) patients, each in group B and C. However, for management of verruca plana MMR was found to be superior to vitamin D3.

Limitations:

Our study was limited by a small sample size, absence of immunological analysis, and limited follow-up period.

Conclusion:

MMR vaccine and vitamin D3 are equally effective and safe treatment option for multiple, recalcitrant warts, as well as warts on difficult to treat sites with minimal recurrence.

Authors: Duan Yan , Li Linye , He Yue , Wang Jian
Published: November 2021

This study sought to analyse tyrosinase (TYR) pathogenic variants in a Chinese Mongolian family with progressive symmetric erythrokeratoderma (PSEK). We collected clinical data and peripheral blood DNA samples from the initial patient and his family members for polymerase chain reaction (PCR) amplification and whole-exome sequencing of the coding region of TYR. Genetic analysis showed a TYR insertion (c. 929_930insC; p.Arg311Lysfs*7) in the patient that was not detected in any of the normal family members or in 100 healthy controls. This report provides the first description of this TYR pathogenic variant (c. 929_930insC) in a family; functional studies and further research are needed for an in-depth analysis.

Published: November 2021

Background:

Psoriasis is a multi-system inflammatory disease where skin and joints are the primary targets. Recently, some studies had shown the association of psoriasis with kidney disease.

Aims:

To study the association of psoriasis with chronic kidney disease (CKD) in a tertiary health care center.

Methodology:

The study was conducted in the Department of Dermatology in a tertiary care center in Kerala. The study was a descriptive cross-sectional study for 6 months from August 2017 to January 2018. A total of 104 patients with psoriasis were studied. Clinical data was collected. Glomerular filtration rate (GFR) and albumin creatinine ratio (ACR) were found out to know the presence of CKD. Descriptive and inferential statistical analysis has been carried out in the present study.

Observations:

Of the 104 patients, 14 were diagnosed as having CKD. Of the 14 CKD patients, 12 had severe psoriasis, 2 had moderate psoriasis, and none had mild psoriasis. The risk factors for CKD (presence of diabetes mellitus/hypertension or intake of drugs—non-steroidal anti-inflammatory drugs [NSAIDs]/cyclosporine) were present in 9 out of 14 CKD patients. The duration of psoriasis was more than 10 years in 10 CKD patients.

Conclusion:

Our study demonstrated that psoriatic patients have an increased risk of developing CKD and this risk is found to increase with the severity and duration of psoriasis. Our results require confirmation in large-patient populations in prospective studies or case-control studies.

Authors: Jakhar Deepak , Kaur Ishmeet , Gupta Rakesh K. , Yadav Shakti
Published: November 2021

The application of a dermoscope in the study of mucosal pathologies is increasingly gaining importance. An easy, noninvasive characterization of pathological changes serves as an aid to dermatologists, sometimes even obliviating the need for histopathology. The aim of the present case series was to describe the mucoscopic features of histologically proven oral leukoplakia. Five consecutive cases of histologically proven oral leukoplakia were included for mucoscopy. Polarized mucoscopy shows white-to-pink structureless areas (100%), intervening pink lines (80%), and surface corrugations (60%). The periphery of the lesions showed white clods (100%) and dotted vessels with irregular arrangement (60%).

Authors: Agarwal Uma S. , Randhawa Navneet K. , Singh Arti , Agarwal Puneet
Published: November 2021

Patients with chronic bullous disease of childhood (CBDC) generally respond well to treatment with drugs like Dapsone and oral and topical steroids. Refractory cases are additionally treated with immunosuppressants like azathioprine, methotrexate, ciclosporin, colchicine, tetracycline, and IVIG (Intravenous Immunoglobulin). However, there are few patients who fail to respond to these therapies and pose a challenge both to the patient and the treating physician. Rituximab has been used widely to treat pemphigus cases in adults, but its use in children has not been much reported. We hereby report a case of a 5-year-old child with CBDC, refractory to other treatments, who responded favorably to Rituximab.

The psychological status of phonological analyses
Authors: Eddington David
Published: November 2021

This paper casts doubt on the psychological relevance of many phonological analyses. There are four reasons for this: 1) theoretical adequacy does not necessarily imply psychological significance; 2) most approaches are nonempirical in that they are not subject to potential spatiotemporal falsification; 3) phonological analyses are estab­ lished with little or no recourse to the speakers of the language via experimental psy­ chology; 4) the limited base of evidence which most analyses are founded on is further cause for skepticism.

Il contributo esamina le caratteristiche (fonologiche, morfologiche, solo marginalmente sintattiche e lessicali) del terzo dei principali dialetti istroromanzi (IR), quello della cittadina di Valle (croato Bale) nell'Istria sudoccidentale, quali esse risultano dai testi vallesi recentemente pubblicati nella Antologia delle opere premiate ai Concorsi d'arte e di cultura Istria Nobilissima (voll. XXI-XXIII e XXV, Trieste-Rovigno 1988-1990 e 1992). Si distinguono i tratti comuni a tutto l'IR da quelli specifici del vallese, e i materiali attuali vengono confrontati in modo sistematico con quelli nelle fonti anteriori (1835-1919, 1900, 1986). Il confronto permette interessanti osservazioni sincroniche e diacroniche nonché sociolinguistiche, illustrando nel contempo l'importanza dei testi studiati.Nei volumi XXI (1988), XXII (1989), XXIII (1900) e XXV (1992) dell'Antologia delle opere premiate ai Concorsi d'arte e di cultura Istria Nobilissima (v. bibliografia; d'ora in poi:Istria Nobilissima) sono apparsi alcuni testi in dialetto vallese istroromanzo (IR) (o istrioto) della cittadina di Valle (in croato Bale), tra DignanoNodnjan e Rovigno/Rovinj nell'Istria sudoccidentale.

Marine tourism is a type of special interest tourism, namely by managing and utilizing marine and coastal landscapes, both those that are managed directly such as swimming, boating, snorkeling, diving, or indirectly such as picnics and beach sports. Nusmapi Island has the potential to be developed as a marine tourism object which has the potential for waters and coral reefs that are in good condition. The purpose of this study was to determine the relationship between the level of public perception and the socio-economic conditions of the local community on Nusmapi Island. In October-November 2020 this research was carried out on Nusmapi Island, Manokwari Regency. The descriptive exploratory method is by conducting a survey to the research location. The data collected were analyzed descriptively by tabulating and displayed in the form of pictures, tables, and graphs to provide an explanation of the information obtained in this study. The relationship between the level of perception and socio-economic and cultural aspects of society was analyzed by multiple regression. The variables of age, gender, education, main occupation, and additional work were positively correlated with community perception, while length of stay and ethnic origin were negatively correlated with perceived level. The correlation value between the 7 independent variables (X1-X7) and the dependent variable (Y) is 0.839 which is included in the very strong category. The value of the coefficient of determination 61% explains the variables in the resulting regression model, the remaining 39% is influenced by other factors outside the model. Age is a significant social variable on people's perceptions of the development of marine tourism on Nusmapi Island. The community as the main component in development has an important role in developing local potential that comes from nature, socio-culture or improving the community's economy through the development of marine tourism.

On Steady-State Voltage Stability Analysis Performance in MATLAB Environment
Authors: Veleba Jan , Nestorovič Tomáš
Published: November 2021

Nowadays, electric power systems have been often operated close to their limits due to increased electric power consumptions, vast installments of renewable power sources and deliberated power market policies. This poses a serious threat to stable network operation and control. Therefore, voltage stability is currently one of key topics worldwide for preventing related black-out and islanding scenarios. In this paper, modelling and simulations of steady-state voltage stability problems in MATLAB environment are performed using author-developed computational tool implementing both conventional and more advanced numerical approaches. Their performance is compared with Simulink-based library Power System Analysis Toolbox (PSAT) in terms of solution accuracy, CPU time, and possible limitations. Their use for both real-time and off-line monitoring and assessment of system's voltage stability are also discussed.

Industrial process planning is principally an association between design and development or final production and has vital function in the manufacturing systems. In this paper the under research industry is security vehicle manufacturing industry in Pakistan. First of all a fundamental process plan is developed and then modeled mathematically using progressive closed loop approach. Mathematically modeled process plan is then optimized in order to find optimal or sub optimal solutions. Research then investigates the capability of an innovative optimization technique called stochastic search in handling optimization of manufacturing process plan. This new technique of stochastic, searches the best approximate process planning solution. Finally the research examines the convergence of optimization techniques to an optimal solution for a manufacturing framework.
Impact of the Sampling Period on the Design of Digital PID Controllers
Authors: Tsamatsoulis Dimitris
Published: November 2021

The impact of the sampling period on the parameterization of a digital PID controller in the frequency domain is attempted using three different digital approximations of the integral action. The controller is implemented in the industrial process of regulation of the cement sulphates in the cement mill outlet. The maximum sensitivity, Ms, has been utilized as a main robustness criterion. For the same Ms, proportional and differential gain, a rise of the sampling period leads to a decrease of the integral gain ki for all the three approximations. For the same sampling period, the function between proportional and integral gain differs for the three approximations studied. If the design satisfies two criteria simultaneously, maximum sensitivity and phase margin in the current study, then the permissible PID gains zone becomes narrower.

Methodology for Measuring the Impact of the Privacy Protection Law on the Use of Big Data
Authors: U-Cheol Oh Ky
Published: November 2021

The ICT revolution triggered by the emergence of smart devices, typically represented by the iPhone and the iPad, is migrating into the new domain of ‘big data’ after passing the turning point of ‘SNS Life,’ which is represented by Twitter and FaceBook among others. These developments have brought significant changes in all areas of politics, economy and culture. The stock prices of Apple, Samsung Electronics, FaceBook and Google fluctuate depending on who takes the hegemony in the changes. Meanwhile, such a reform of the ICT sector has generated some new undesirable sideeffects, including online disclosure of personal information, malicious comments, Smishing or other forms of financial scams. As we cannot abandon either big data or privacy protection, it is critical to find a compromise. It seems both evident and selfexplanatory that the use of big data, which is attributable to technical innovation, conflicts with privacy protection based on the idea that individuals should be allowed to determine the disclosure or not of their personal information. Yet, the problem here is that the discussion of countermeasures remains at the level of catching the wind with a net. Therefore, this paper intends to present a framework that can objectively verify what impact the enhanced legal regulation concerning privacy protection has on the use of big data as the first step in exploring a compromise between the use of big data and privacy protection.

Scots pine (Pinus sylvestris L.) is one of the most widespread and economically most important tree species in Latvia. Scots pine forest health and element flow changes have been monitored in Latvia within the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) with assessment of crown condition and damaging agents at 115 Level I monitoring sites (mostly oligothrophic and mesotrophic Vacciniosa, Myrtillosa and Hylocomiosa forests) and with sampling and analyses of environmental samples at three Level II monitoring sites representing typical Scots pine forests (Myrtillosa) in hemiboreal conditions in Latvia. This study summarizes the background information and presents the trends of forest health, carbon turnover and environment condition in Scots pine forest since 2009. In general, defoliation rate in Scots pine stands remains stable for the studied period, with some yearly fluctuations, possibly related to regional insect outbreaks, especially well demonstrated in two Level II plots. The share of damaged trees varied by year from 12.8% to 19% of the total number; the main cause of damage was direct action of man. Chemical element flows in Scots pine forests in Level II monitoring plots have been relatively stable as well except the decreasing trend in total N concentration in deposition and SO4-S concentration in soil solution and increasing trends in DOC concentration in soil solution that is in line with common trends in Europe. Carbon input with above-ground litter was relatively stable during the whole period; however, interannual variations were rather wide.

BRASIL DO “MILAGRE” E “ANTIMILAGRE” ECONÔMICO: A SAÍDA DA CRISE DE 1980 NA INTERPRETAÇÃO DE IGNÁCIO RANGEL
Authors: NOGUEIRA LEANDRO
Published: November 2021

Esse artigo analisa a interpretação que Ignácio Rangel fez da crise econômica brasileira dos anos 1980 e a conclusão a que chega: a necessidade de conceder os serviços de utilidade pública à iniciativa privada como alternativa para sair da maior e mais prolongada crise desde o início da industrialização do país. Segundo Rangel, as mudanças institucionais entorno da concessão viabilizariam a transferência de recursos ociosos presentes no Departamento I (indústria pesada) para a área estrangulada da economia brasileira, os serviços de utilidade pública. Desse modo, criaríamos um forte aparelho de intermediação financeira capaz de levantar e orientar esses recursos ociosos no desenvolvimento do país. Mais do que isso, essa alternativa representaria, na sua interpretação, a última etapa da substituição industrial de importações e a consolidação do capitalismo brasileiro. No entanto, o que assistimos foi a implantação de um modelo que dificultou a continuidade das transformações pelas quais a economia brasileira vinha passando. A partir da sua interpretação do capitalismo brasileiro, Rangel desenvolveu um diagnóstico e propôs uma intervenção, mas a história desenrolou-se na contramão do que ele propunha.

Published: November 2021

Renewable energy generation is no more an alternative rather it becomes a choice for the power generation to meet the upcoming energy demand. Considering the non- renewable energy unavailability, as well as, the environmental impact, renewable energy should be the first choice. Most of the power generation in Bangladesh comes from nonrenewable energy and a noticeable amount of energy is imported from abroad. As a developing country, it is not cost-efficient and never ensures energy security. To ensure long-term energy security, it is time to shift power generation from nonrenewable to renewable energy generation. This paper presents an approximate calculation for the renewable power generating plant cost and returning year. The cost calculation is done in the context of Bangladesh.

Published: November 2021

Outcome-based learning (OBL) is a tried-and-true learning technique based on a set of predetermined objectives. Program Educational Objectives (PEOs), Program Outcomes (POs), and Course Outcomes are the three components of OBL (COs). Faculty members may adopt many ML-based advised actions at the conclusion of each course to improve the quality of learning and, as a result, the overall education. Due to the huge number of courses and faculty members involved, harmful behaviors may be advocated, resulting in unwanted and incorrect choices. The education system is described in this study based on college course requirements, academic records, and course learning results evaluations is provided for anticipating appropriate actions utilizing various machine learning algorithms. Dataset translates to different problem conversion methods and adaptive methods such as one-versus-all, binary significance, naming power set, series classification and custom classification ML-KNN. The suggested recommender ML-based system is used as a case study at the Institute of Computer and Information Sciences to assist academic staff in boosting learning quality and instructional methodologies. The results suggest that the proposed recommendation system offers more measures to improve students' learning experiences.
