This paper presents a review of the State-of-the-Art Techniques for Power Flow Analysis (PFA) that are newly proposed. However, some of the existing classical methods for the Power Flow Analysis such as Newton-Raphson method, Gauss-Siedel method, and Fast Decoupled Power Flow Technique were also discussed so as to give a background and a wider view of the improvements recorded so far. From the findings, the State-of-the-Art Techniques such as Particle Swamp Optimization Algorithm for optimal Power Flow Incorporating Wind Farms, Hybrid Firefly and Particle Swamp Optimization Algorithm, Mann Iteration Process Technique for III-Conditioned System, and A New Approach Newton-Raphson Load Flow Analysis in Power System Networks with STATCOM have shown superiority over and above the existing classical methods in terms of accuracy, speed of convergence and overall efficiency. Particularly, there are two newly proposed methods for dc grids: Direct Matrix–Current application (DM-CA) and Direct Matrix-Impedance Approximation (DM-IA) methods that stand out with respect to accuracy, convergence and computational effort which means they can be used for planning, optimization and analysis purposes of practical dc grids.

Authors: Carlos Eduardo Rivera  , Sebastian Canal  , Ankur Seth
Published: March 2023

Abstract Objective: To establish Central Corneal Thickness associations with systemic factors in six cities of Colombia. Methods: A cross-sectional study was conducted in Colombia among hypertensive and diabetic patients. Two thousand sixty-seven subjects older than 50 diagnosed with SH and DM were included. Participants underwent a complete ophthalmic examination, including intraocular pressure (IOP) measurement by Goldmann tonometry, Central Corneal Thickness (CCT), and Blood pressure. The glaucoma diagnosis was confirmed by structural and functional evidence. Results: In multiple regression analysis, a trend of thinner corneal thicknesses was observed, with increasing decades of life, 60 - 69 years (-7.14 microns (μm) p: 0.58), 70- 79 years (-2.05 μm p: 0.38), > 80 years (-7.3 p <0.056) being almost statistically significant only in patients older than 80 years. Female patients had thinner CCT (- 5.04 μm) than male patients. African- Colombian patients had thinner corneas (-9.6 μm) than mestizo patients (P= 0.002). Patients with migraine had thicker CCT (6.83 μm p <0.024) compared with no- migraine patients. Diabetic patients had thicker CCT (3.91 μm) than non-diabetic patients (P= 0.039). Finally, a 0.66 μm increase per mm hg of the systolic pressure (P=0.024) and a 0.99 μm decrease per mm hg of Systolic Perfusion Pressure (P=0.038) was observed, but no association was found between CCT and Systemic Hypertension. Conclusion: Our study highlights the relationship between systemic factors such as age, sex, race, DM, systolic blood pressure, migraine, and systolic perfusion pressure with an ocular biomarker such as CCT
PRIORITIZATION OF TREE SPECIES BASED ON GREEN LEAF NUTRIENT LEACHING: AN APPROACH FOR SUSTAINABLE AGROFORESTRY PRACTICES
Authors: Hasanuzzaman Md. , Hossain Mahmood
Published: March 2023

Nutrients leaching from litter (leaves, bark, needles and twigs) have a major contribution to the supply and cycling of nutrients to crops. Among the litter parts, leaves are the main and quick source of organic matter to the soil whereas, green leaves return more nutrients than other forms of leaves. The return potentiality of K, P and N through leaching from green leaves of the major agroforest tree species: Zizyphus jujuba, Melia azadirachta, Albizia saman, Dalbergia sissoo and Azadirachta indica are presented on this study. Green leaves of the studied tree species were collected and then leached in water (deionized). Nutrient release through a leaching experiment was conducted for 192 hours. Percentage (%) of green leaf mass loss and Total Dissolved Solid with Electrical Conductivity of the collected leaching water showed a curvilinear relationship with time significantly (p < 0.05). NH4, PO4 and K concentration of the collected leaching water of the individual cropland agroforest tree species was significantly (p < 0.05) increased for 72 hours in the initial stage but at the later stage remained constant. Individual tree species showed the same nutrient release (K > NH4 > PO4) pattern. The highest concentration of 5121 ppm NH4 and potassium (13357 ppm) was found for Melia azadirachta and the lowest concentration of 1424 ppm NH4 and potassium (4410 ppm) was observed for Albizia saman. Results from the study highlighted that M. azadirachta was the best among the studied tree species in terms of nutrient return followed by A. indica and D. sissoo.

Stigma, Type D personality, and attitudes to seeking coaching among working people
Authors: Murphy Mike , O’Donovan Hugh , O’Leary Pat
Published: March 2023

Introduction

Whilst a good deal of research has been conducted on predictors of attitudes to seeking counselling and/or psychotherapy, no such work has been conducted in relation to coaching. Type D personality, public stigma and self-stigma are potential significant predictors of such attitudes, with Type D possibly having an indirect effect mediated by stigma. Type D personality may also be linked to increased burnout, in which case those with this personality type might benefit more from coaching support.

Aims

This study aimed to (a) assess the relationships between attitudes to seeking coaching and each of Type D personality, public stigma and self-stigma; (b) examine the possibility of Type D personality having a relationship with attitudes to coaching which is mediated by stigma; and (c) address the relationship of Type D personality to burnout, in a sample of working people.

Method

A cross-sectional, online survey was employed.

Results

Type D personality, self-stigma and public stigma were all significantly negatively correlated with attitudes to seeking coaching. The relationship of Type D personality to such attitudes was fully mediated by public stigma, but not by self-stigma. Type D personality was significantly associated with all dimensions of burnout.

Implications

People with higher Type D personality scores are more likely to experience burnout, and so may stand to benefit more from coaching. They are also more likely to have poorer attitudes to seeking coaching – a relationship mediated by public stigma. Public and self-stigma are also related to poorer attitudes. Thus public material which targets stigma can improve attitudes to seeking coaching generally, with a particular benefit to those with Type D personality.
The use of coaching as a tool to improve coping in victims of workplace bullying
Authors: Quiun Laura , Herrero Marta
Published: March 2023

This pilot study, based on Quiun’s (2017) theoretical model, aimed to improve the wellbeing of victims of workplace bullying through their coping strategies. Ouiun’s (2017) model highlights the importance of rumination in workplace bullying’s psychological effects as well as the negative role of thinking in its development. The program used the reflective nature of coaching and the benefits of autogenous meditation in stress management training to promote coping skills and to reduce activation levels. The participants were people who reported being targets of workplace bullying. They were assessed in the three factors of rumination (Brooding, Reflection and Negative Thinking) and wellbeing levels at pre- post- and three-month after the end of the study to identify change levels resulting from the program. Wilcoxon-Mann-Whitney and the index for reliable change were employed to determine the statistical significance of the change, while Grounded Theory principles were used to explore qualitatively how coaching worked on promoting change. The quantitative analysis showed a significant change in negative thinking level (z=-1.98 p<.048) between post-intervention and three months after the project. The qualitative analysis indicates how coaching improves coping skills, self-esteem and personal growth, with the alliance with the participants and autogenous meditation suggested as the key elements that facilitated this change.

This article seeks to understand and explain the importance of Islamic education in comparison to Western education through a detailed examination of the challenges and expectations as seen through the eyes of Muhammad Iqbal. The research method employs a review of the literature to identify previous sources of relevant articles and journals. In this article, the author adopts the viewpoint of Muhammad Iqbal, a modern Islamic philosopher, writer, and reformer, to examine the benefits and drawbacks of Islamic and Western education. The discussion revealed that there is a significant difference between Islamic education and Western education, particularly in terms of scope and source material used. According to Muhammad Iqbal, Western education produces people with general science intelligence, whereas Islamic education produces people with good character and behavior. A good education must strike a balance between physical and spiritual aspects. Education's goal is to prepare men for life. Islamic education should be taught from childhood to adulthood so that the education provided covers a wide range of scientific topics. In the West, empirical aspects of real-life experience place a greater emphasis on educational resources. Whereas in Islamic education, the source of the value of knowledge comes directly from the creator of the universe rather than from the creation of experts or the elite of society. Because education is an investment in a better future; therefore, the educational process must run smoothly.

Authors: V Balaji , Patil Deepa , S Geetha , Patil Umakant
Published: March 2023

Background: Epilepsy is a disorder of brain function indicating periodic and unpredictable occurrence of seizures. Hypertension is the main cause of intracerebral hemorrhage which is a triggering factor for development of epilepsy. Nebivolol, a β-blocker is an anti-hypertensive drug, could decrease the glutaminergic transmission with addition of antioxidant property as a contributing factor may possibly provide anticonvulsant effect.

Aim and Objective: The aim of the study was to study the anticonvulsant effect of Nebivolol in Albino mice.

Materials and Methods: An either sex of Albino mice weighing between 18 and 22 g were used. Forty-eight animals (n = 48) were divided into eight groups with six in each group; four groups each for maximal electroshock (MES) and pentylenetetrazole (PTZ) models, respectively. Hind Limb Flexion, Hind Limb Extension, Clonus, and Postictal Depression were observed using MES model, Seizure latency and Duration of seizures were observed using PTZ model.

Results: Nebivolol showed anticonvulsant effect with MES convulsions at both 0.25 mg/kg and 0.5 mg/kg but this effect is not equivalent to that of phenytoin in the present study. In terms of duration of tonic hind limb flexion and post-ictal depression, Nebivolol 0.5 mg/kg dose has comparable results to that of phenytoin. In PTZ model, Nebivolol decreased the seizure duration but did not delay the seizure onset, which were comparable to the standard Diazepam.

Conclusion: Nebivolol may possibly be beneficial in treating generalized tonic clonic seizures and absence seizures. However, more extended studies are needed to prove the anticonvulsant effect of Nebivolol and enable its use in clinical practice.

Authors: Prajapati Vipul , Modi Krishna , Mehta Yash , Malhotra Supriya
Published: March 2023

Background: The drug promotional literature (DPL) provided by the medical representative is a crucial source of information for busy medical practitioners. It is frequently the only resource that treating doctors rely on to stay up to date on both new and existing medications. Because pharma companies are promoting the information for their own brand of drugs, there is a possibility of prejudice.

Aims and Objectives: This study was conducted to assess DPL using the World Health Organization (WHO) criteria.

Materials and Methods: This cross-sectional study was conducted by collecting 300 DPLs randomly from private medical hospitals and some pharmaceutical companies’ representative from Ahmedabad. The WHO criteria for drug promotion were used to analysis of all obtained DPLs.

Results: Among 300 DPLs, 251 were included for analysis as per inclusion criteria. Out of 251 DPLs, drugs acting on cardiovascular system (61) were promoted most followed by drugs acting on endocrine system (45), antimicrobial (39), and gastrointestinal tract system (33). Majority of brochures were providing information regarding brand name (249), dosage form (231), uses (225), and dose information (207). Very few literatures mentioned details such as side effects, warning, contraindications, precautions, and interactions. Average 2.91 claims were made for per each DPLs. Out of 83 references, majority of references were from journal articles. Very few DPLs have data that are displayed in scientific figures and tables. Among analyzed DPLs, majority them contain various pictures of medicines, organ part, and women.

Conclusion: Majority of DPL were not following ethical standard as per the WHO guidelines and their purpose seems like commercial gain.

Background: Sperm morphology is the major benchmark in assessment of male infertility. There are limited studies available on frequency of qualitative defects of sperm in patients with normal sperm count. Hence, the present study was done to assess the morphological defects in patients with normal sperm counts who came for infertility work up.

Aims and Objectives: The aim of the study was to evaluate the correlation of qualitative defects of sperm in patients having normal sperm counts.

Materials and Methods: We have collected 70 samples with normal sperm count (≥15 million/mL). After routine sperm count and motility, Smears were fixed in ethanol and stained with Papanicolaou stain. Minimum of 200 spermatozoa were analyzed per sample. We have recorded normal sperm morphology and abnormal morphology and we have further categorized the data. Morphology was categorized as defect in head, middle piece and tail.

Results: Most common morphological abnormalities detected in head region were double head (60%) followed by tapering head (42%). Most common defect observed in middle piece region was thick middle piece (57%) followed by bent neck (48%). Most frequent defect in tail region was coiled tail (14%). We have recorded 40 cases (57%) out of 70 showed multiple morphological defects.

Conclusion: Qualitative defects in sperm play a key role in infertility workup. We must have to acknowledge the importance of morphological assessment of semen.

Background: Chronic obstructive pulmonary disease (COPD) is heterogeneous lung condition presenting with chronic respiratory symptoms. Pathogenesis of the disease process includes exposure to noxious particles and gases starting accelerated inflammation. Individual genetic make-up and environmental factors play role in disease process. COPD shows persistent airflow limitation affecting airways and alveoli. They can be affected individually or at the same time. Hence, each patient experiences COPD as a different amalgamation of bronchitis, bronchiolitis, and emphysema. We set to find out individualized clinical profiles in COPD for same reason.

Aims and Objectives: The aim of the study was to build a clinical and spirometric profile of diagnosed COPD patients presenting to a tertiary health care center in Vadodara.

Materials and Methods: A retrospective analysis of records 425 COPD patients was conducted. Relevant clinical data were collected from excel sheet along with spirometric findings.

Results: Average age of presentation was 58.10 years. Lowest age was 40 years. Out of 425 patients, 352 (82%) were males and 73 (18%) were females. Out of total, 263 (62%) were smokers and 162 (38%) non-smokers. Most common presenting symptom was cough with expectoration in 423 (99.5%) patients followed by breathlessness in 412 (96.9%), fever in 148 (34.8%), and pedal edema in 38 (8.9%). Average forced expiratory volume in 1s at presentation was 43.27 L/min. Out of total admissions, 61 (14.3%) were classified as very severe, 249 (58.5%) as severe, and 115 (27%) as moderate according to COPD Global initiative for obstructive lung diseases severity classification.

Conclusion: COPD is considered as disease of old age and associated with smoking, our study showed more than one-fourth of the population as non-smoker. To avoid under-diagnosis, COPD should be considered in younger age group and non-smokers.

Published: March 2023

A global recession is predicted to occur in 2023. In facing this condition, MSMEs have a key role in maintaining economic growth in Indonesia. Despite the significant potential to contribute to the Indonesian economy, many MSMEs still do not register as taxpayers. As a result, tax revenues in Indonesia have not been optimal. In addition, the phenomenon of MSME tax non-compliance has the potential to increase with the existence of regulations governing VAT rate increases. This study aims to review the potential for MSME tax compliance after the increase in VAT rates. This study uses a qualitative method using a content analysis approach. The data used in this study is MSME data sourced from the Ministry of Cooperatives and Small and Medium Enterprises website. In addition, this panel research data also uses MSME tax compliance data from the Directorate General of Taxes website. A review of data sourced from the content analysis is further elaborated using scoping review. This study concludes that there is potential for an increase in MSME tax compliance following an increase in the VAT rate. The increase in MSME tax compliance is projected to increase Indonesia's overall tax revenue. Thus, MSMEs have a significant role in facing a recession.

The hike in world coal prices that occurred in 2021 is a breath of fresh air for coal mining companies around the world, including Indonesia. This hike is called windfall profit because the hike is influenced by other factors beyond the control of the coal mining entrepreneur. On the other hand, along with this fresh breeze, the Indonesian people's economy has been declining due to the Covid-19 pandemic. The occurrence of this imbalance prompted this research to be conducted to find out whether the windfall profits experienced by coal mining companies in Indonesia can be subject to windfall tax. This research uses qualitative methods with literature study techniques. By looking at the condition of coal mining companies in Indonesia, the application of the windfall tax in other countries, and studying the taxation regulations for coal companies currently in effect in Indonesia, this research results that the application of the windfall tax on coal exports can act as an instrument for a source of state revenue as well as an automatic stabilizer instrument of domestic coal commodities availability. The scheme that can be applied based on this research is taxation of additional income which is temporary for short term purposes and permanent taxation for long term purposes.
Kenaikan harga batu bara dunia yang terjadi pada tahun 2021 merupakan angin segar untuk perusahaan tambang batu bara di seluruh dunia termasuk Indonesia. Kenaikan ini disebut dengan windfall profit karena penyebab kenaikan tersebut dipengaruhi oleh faktor lain di luar kendali pengusaha tambang batu bara. Di sisi lain, berbarengan dengan angin segar tersebut, perekonomian masyarakat Indonesia mengalami penurunan akibat pandemi Covid-19. Terjadinya ketimpangan ini mendorong penelitian ini dibuat untuk mengetahui apakah atas windfall profit yang dialami oleh perusahaan tambang batu bara di Indonesia dapat dikenai windfall tax. Penelitian ini menggunakan metode kualitatif dengan teknik studi literatur. Dengan melihat kondisi perusahaan tambang batu bara di Indonesia, penerapan windfall tax di negara lain, dan mendalami peraturan pemajakan perusahaan batu bara yang sedang berlaku di Indonesia, penelitian ini menghasilkan bahwa penerapan windfall tax atas ekspor batu bara dapat berperan sebagai instrumen sumber penerimaan negara sekaligus instrumen automatic stabilizer ketersediaan komoditas batu bara domestik. Skema yang dapat diterapkan berdasar penelitian ini adalah pemajakan atas tambahan penghasilan yang bersifat sementara untuk tujuan jangka pendek dan pemajakan bersifat permanen untuk tujuan jangka panjang.

El objetivo del presente trabajo fue describir las características clínicas de los pacientes con sospecha o confirmación de COVID-19 hospitalizados en el Centro Médico Docente La Trinidad (CMDT) entre agosto y septiembre del 2020. Metodología: estudio de tipo observacional, serie de casos. La muestra de 144 pacientes se obtuvo por muestreo aleatorio. Resultados: la mayoría fueron pacientes entre 60-79 años (42,1%) a predominio masculino (69%). Se obtuvo confirmación diagnóstica de COVID-19, sólo en el 13,2% de los casos.  El 64% presentaban comorbilidades, predominantemente cardiovasculares y metabólicas. Los principales motivos de consulta fueron disnea (53,5%), fiebre (15,9%) y tos (12,5%); 62,5% recibió tratamiento ambulatorio previa hospitalización. Durante la hospitalización 89,5% recibió esteroides, 91,6% recibió anticoagulantes, y 36,8% tratamiento antiviral. El 11,1% de los pacientes ingresó a la Unidad de Terapia Intensiva (UTI), de los cuales, 56% requirió ventilación mecánica. La mortalidad encontrada, fue de 10.4%, inferior a la reportada en la literatura, y principalmente en UTI (6,3%). Se evidenció elevación del dímero D entre los 7-9 días de enfermedad mientras que los reactantes de fase aguda aumentaron progresivamente el curso de la enfermedad, presentando un pico entre los 13-15 días posterior al inicio de los síntomas. Conclusión: la disnea resultó ser el principal motivo de consulta en este estudio. Considerar los parámetros bioquímicos relacionados a hepatopatía y posibles implicaciones de hipoalbuminemia en el edema intersticial. El seguimiento de reactantes de fase aguda puede predecir la aparición de tormenta de citoquinas entre los días 13-15 de enfermedad.

DULP: complessità , organicità , liquidità
Authors:   University of Rome Tor Vergata - Dip. SPFS, Giovannella Carlo
Published: March 2023

Un intervento che, senza pretese di universalità ontologica, intende contribuire alla costruzione di una visione condivisa sulla natura di un sistema complesso, nella speranza che essa possa fungere da quadro di riferimento, flessibile, entro il quale ragionare del DULP. A partire dalla descrizione di alcuni comportamenti identificativi della natura complessa di un sistema, si procederà nella descrizione di alcuni ingredienti e di alcuni tratti caratterizzanti la complessità sistemica con l’obiettivo di identificare i ‘motori’ delle ‘emergenze’ e le corrispondenze tra sistemi complessi e organici. La presa d’atto della rilevanza del contesto ci condurrà ai concetti di coevoluzione e liquidità sistemica. La mappatura di tale quadro al mondo dell’apprendimento e l’assunto della centralità della persona ci condurranno alla valorizzazione degli approcci ai processi ‘design inspired’ e a discutere alcune delle caratteristiche di quello che potremmo definire una sorta di lento crossover verso l’affermarsi di un nuovo paradigma.
Complex Learning. Un modo possibile di essere DULP
Authors: Guglielman Eleonora
Published: March 2023

La sfida raccolta da DULP richiede un approccio innovativo che consenta di riconsiderare le pratiche e l’idea di formazione, allo scopo di offrire supporto a forme di apprendimento che vanno assumendo un carattere temporale, spaziale e culturale sempre piuÌ ubiquo e che si svolgono in contesti sempre piuÌ liquidi e coevolutivi, in cui l’individuo deve necessariamente apprendere a gestire la propria personale realizzazione e il proprio essere sociale. Il modello di Complex Learning per le sue caratteristiche di apertura, dinamicitaÌ, flessibilitaÌ, ibridazione (tra ambienti, linguaggi e modi di interazione) appare essere una risposta efficace rispetto alla scommessa di accettare la complessitaÌ, l’ “organicitaÌ” e quindi l’imprevedibilitaÌ delle forme, delle strade e degli esiti dell’apprendere. Ma, quanto puoÌ essere DULP il Complex Learning? In che modo consente di ripensare gli schemi e i luoghi noti dell’apprendimento? A partire da una necessaria e preliminare definizione di cosa sia Complex Learning, si propongono, in questo articolo, alcune possibili risposte.
L’apprendimento tra reale e virtuale: percorsi, processi identitari e appartenenze comunitarie
Authors: Volterrani Andrea , Spinelli Angela
Published: March 2023

L’articolo vuole contribuire teoreticamente e metodologicamente al dibattito sulle comunità virtuali come comunità di apprendimento.1 La prospettiva pedagogica e didattica è filtrata dalle lenti della sociologia per proporre una prospettiva in cui individuo e comunità, didattica e tecnologia risultino orientate e finalizzate ad un progetto pedagogico più ampio: costruire e condividere conoscenza attraverso la costruzione e la condivisione di comunità aperte e transitabili, in cui ciascuna identità abbia la possibilità di riconoscersi come progetto individuale e relazionale. L’indirizzo eÌÂ che una nuova relazionabilità sociale è possibile solo in un contesto open, di scambio, ma anche – e soprattutto – di transito e contaminazione. L’idea di comunità “chiusa” come presente in letteratura [1-2], perciò, è oggetto di analisi critica.

Published: March 2023

L’organizzazione di un wiki web a scuola può fornire l’opportunità per un miglioramento delle competenze disciplinari. In questa esperienza la metodologia del learning by doing trova una piena applicazione e diventa spunto di riflessione sui problemi che si incontrano nell’istruire all’uso delle nuove tecnologie e sulla necessità di educare ai corretti comportamenti all’interno dei social network. All’osservazione dello sviluppo dell’attività si affiancano l’analisi delle implicazioni sulle competenze in campo matematico, nonché l’esame delle difficoltà incontrate a livello tecnico e comportamentale.
