Nonlinear optimization algorithm using monotonically increasing quantization resolution
Authors: Seok Jinwuk , Kim Jeong‐Si
Published: May 2022

We propose a quantized gradient search algorithm that can achieve global optimization by monotonically reducing the quantization step with respect to time when quantization is composed of integer or fixed‐point fractional values applied to an optimization algorithm. According to the white noise hypothesis states, a quantization step is sufficiently small and the quantization is well defined, the round‐off error caused by quantization can be regarded as a random variable with identically independent distribution. Thus, we rewrite the searching equation based on a gradient descent as a stochastic differential equation and obtain the monotonically decreasing rate of the quantization step, enabling the global optimization by stochastic analysis for deriving an objective function. Consequently, when the search equation is quantized by a monotonically decreasing quantization step, which suitably reduces the round‐off error, we can derive the searching algorithm evolving from an optimization algorithm. Numerical simulations indicate that due to the property of quantization‐based global optimization, the proposed algorithm shows better optimization performance on a search space to each iteration than the conventional algorithm with a higher success rate and fewer iterations.

Authors: Mohammed Ibrahim , Wondie Ayalew , Mengist Minwyelet
Published: May 2022

The present study was conducted to assess the environmental quality status and macroinvertebrate community structures of wetlands using macroinvertebrates as bioindicators. A multimetric biotic index approach was used for the study. The findings revealed 3,367 macroinvertebrates belonging to 37 families. The percentages of Ephemeroptera, Odonata, and Tricoptera (%EOT), percent Diptera, percent filterercollectors, the ratio of Ephemeroptera, Plecoptera, and Trichoptera to Chironomid (EPT/C), the Biological Monitoring Working Party Score, and the Shannon–Wiener diversity index were all significantly related to human disturbance and could be used to assess water quality. Based on the macroinvertebrate index, human disturbance had a significant impact on Shesher wetland, a relatively lower impact on Avaji and Yitamot, and a moderate impact on Chimba, while Dena and Wonjeta had good habitat quality. Their water quality was very poor, poor, moderate, and very good, in that order. Farming, leather tanning, waste dumping, and effluent discharges were responsible for the poor habitat quality of impacted wetlands. Therefore, unless managed properly, human disturbance activities in the wetlands catchment were threatening macroinvertebrates and the wetlands ecosystem. Hence, implementation of catchment-based management together with continuous health status monitoring and a standalone wetland policy should be established.
Formulation d’une pommade antalgique et anti-inflammatoire à base d’un extrait hydroalcoolique des écorces de racines de Securidaca longepedunculata Fresen (Polygalaceae)
Authors: Dembélé Daouda Lassine , Dénou Adama , Haidara Mahamane , Sanogo Rokia
Published: May 2022

Securidaca longepedunculata is a plant commonly used by African populations. Previous works have identified the main bioactive constituents; study the toxicity, analgesic, anti-inflammatory, antioxidant activities of the root barks. This work aims at developing an Improved Traditional Medicine (ITM) in ointmentbased on the hydroethanolic extract of the root barks. The plant material was analyzed to determine the physicochemical parameters. The hydroethanolic extract was used to formulate ointments with shea butter. The quality parameters of the ointment were determined and the primary irritability was checked in albino rabbits. The local anti-inflammatory activity was evaluated against croton oil and xylem inflammation in mice. It exhibited stability at a temperature of 30°C and showed no skin irritation. It inhibited 27% of the inflammation to croton oil. Triterpenic saponins and antiradical constituents were the main chemical markers identified. These results and the existing data can be used for the development of “SECUDOL ointment”, an ITM against painful and inflammatory joint manifestations.
Die ontwerp en gebruik van ’n generiese akademiese woordelys vir universiteitstudente in die onderrig-leer-konteks

Dit is nodig dat universiteitstudente wat ’n nuwe, uitdagende, onbekende en robuuste omgewing betree, ook oor die nodige akademiese taalvermoë en woordeskat moet beskik om suksesvol in hulle studies te wees (Nagy & Townsend, 2012). Dit is egter makliker gesê as gedaan, want wie is veronderstel om die verantwoordelikheid hiervoor te neem en hoe behoort woordelyste en woordeskatontwikkeling by onderrigleer geïntegreer te word ten einde studiesukses aan te help? Dit is trouens selde die geval dat dosente suksesvol op woordeskatontwikkeling (ingesluit vakterminologie) in hul klasse fokus. Ten einde meer lig op hierdie aangeleenthede te werp, word as teoretiese begronding die model vir kommunikatiewe bekwaamheid en steierwerkteorie in hierdie artikel voorgehou. Aan die hand hiervan word daar aangetoon hoe generiese akademiese woordelyste, in hierdie geval die ICELDA-SADiLaRwoordelys, as ’n ondersteuningsmiddel aangewend kan word, nie net as ’n hulpbron by die skryf van ’n akademiese teks nie, maar ook vir gebruik in die groter onderrig-leer-aanbod.
A qualitative exploration of the management of grammar structures by English language curriculum advisors in concert with FET educators
Authors: Mashiane Mmetlane Valery , Ngoepe Lucia Junia
Published: May 2022

The aim of this paper is to explore the management of grammatical structures by the Limpopo Province (LP) English First Additional Language (EFAL) Curriculum Advisors (CAs) in the Further Education and Training (FET) phase. The majority of English language learners’ language proficiency and accuracy are not at an acceptable level and this brings into close scrutiny the quality of teaching and learning that takes place in English language classrooms, and in particular, the effectiveness of teaching grammar structures in EFAL. The research design is exploratory and the approach is qualitative. A selected number of EFAL CAs in the LP participated in the exploration. The paper is underpinned by an integration of Behaviourism, Mentalism, Cognitive and Universal Grammar theories. Findings indicate that educators need more systematic support regarding addressing grammar structures since interlanguage, grammar permeability, and the inappropriate handling of grammar structures appear inherent.

Un ejemplo clave de analogía persuasiva: consideraciones sobre el nudo mágico.
Authors: Marco Simón Francisco
Published: May 2022

Este trabajo analiza los rasgos esenciales de un tipo de analogía persuasiva omnipresente en los rituales mágico-religiosos: la noción metafórica de nudo o atadura mágicos, tanto en rituales de execración de enemigos o víctimas, como en prácticas apotropaicas tendentes a proteger al cuerpo de la víctima de amenazas externas tanto humanas como sobrenaturales. Se analizan las variantes mejor conocidas correspondientes al mundo antiguo, aunque se contemplan también los paralelos y perduraciones de rituales similares en épocas más recientes.
Womenʼs Rights vs. Gender Justice? Exploring Oppositional Womenʼs Organizations and the Reshaping of Feminist Engagement in De-democratizing Turkey
Authors: Ehrhart Anna
Published: May 2022

Reflective of a wider, global trend of changing civil society space and anti-gender backlash against womenʼs rights, research is increasingly interested in exploring the dynamics and implications of hybrid and authoritarian regimes strategies toward civil society, and womenʼs organizations in particular. Nevertheless, few have focused on studying the role of governmental womenʼs organizations – so-called women-GONGOs - as mechanisms of regime strategies, such as in the case of competitive-authoritarian Turkey where women-GONGOs aim to constrain civil society space and feminist, gender equality-oriented discourse and practice. In this study, the aim is to explore how feminist, oppositional womenʼs organizations, despite their “outsider” positions in Turkeyʼs civil society, use and reshape feminist strategies to adapt, renegotiate or resist women-GONGOs as mechanisms of control, co-optation and regime interference.Based on in-depth interviews with 21 womenʼs organizations in Turkey, the study finds that “outsider”, feminist womenʼs organizations in competitive-authoritarian Turkey perceive the influence of women-GONGOs as central to possibilities and limitations in civil society and womenʼs organizing. Consequently, interviews show that “outsiders” employ a variety of feminist strategies, mostly in combination, to create or maintain their activism and operations within the Turkish de-democratization context, for example turning to grassroots in combination with finding new alliances, or connected to sustaining activities within broader democratization movements. However, the study suggests that the changing space of civil society in Turkey affects these “outsiders” in different ways; for example service-oriented womenʼs organizations are less constrained in their feminist strategies compared to claims-making “outsiders”. Lastly, the study illustrates how the dominant role of women-GONGOs in Turkey impacts feminist discourse and practice of “outsiders”, thereby providing empirical insights and theoretical contributions to better understanding transformations of feminist engagement in Turkey and similar gendered de-democratization contexts across the Mediterranean and beyond.
A Phylosophical view of the Problem of Symbolic Form
Authors: Katušić Krešimir
Published: May 2022

Even if it is a tangible, symbol belongs to the domain of the image because we experience it with sight. It is precisely this original domain that is the link that completes communication, because after all, before language there was an image provided to us by the organ of sight, the eye. We first saw, and only later adopted the language which proves the analogy of the connection of these two forms of communication. What we cannot say with language, we try to convey with a picture. Every culture complemented this communication problem with a symbol that sought to touch the sacred, the unspeakable. At first glance sometimes by a different form, but with a common essence.The course of the development of the symbolic form, what it represented and how man used it in the past and how it is used now, seeks to show within the opinions and research of individual authors who have dealt with the problem of symbolic form.This is also the introductory part of the doctoral thesis “Sculpture as a symbolic form in the artistic-ritual act - Nexus” which sought to prove the universality of the individual creative process as a form that allows man to self-knowledge.
Hybrid News for Hybrid Times
Authors: Fejzić-Čengić Fahira
Published: May 2022

Hybrid genres include infotainment, infomercial, arguetainment, communication stampede, spin, and media spectacle. In altered social circumstances, the usual elements of existence as a society, citizen, and public are transformed into the market, consumerist and commercial. Conventional information education becomes ad hoc commercial education. Instead of genuine media content that seeks a media audience that resonates with it, there is advertising (entertainment) through private media intended for consumers. In a construed reality, media corporation owners are not interested in the citizen, but in profit. The consequences include social spectacularization, the illusion of de-ideologization, celebrity culture, and the fact that we are generally becoming shallow. The pandemic has further intensified these trends, which in the horizons of media philosophy may be primarily considered as a Neronian intensification of fear on a global scale.

The academic system of higher education includes three types of institutions: universities, vocational schools and technical schools. Training programs consist of academic and political subjects. Higher education for further education corresponds to postgraduate and doctoral studies. Also in the DPRK, there are in parallel two sectors of higher education: regular and education for the working population. Higher education is not compulsory in North Korea.
Post Traumatic Stress Disorder (PTSD) Following Craniomaxillofacial Trauma - A Five Year Retrospective Study
Authors: Jeyaraj Priya
Published: May 2022

Introduction: The psychological and psychiatric derangements as well as psychosocial impact that craniomaxillofacial trauma can have upon patients, often goes undetected, ignored and unaddressed. This can adversely affect the mental and physical well-being of the patient, leading to a lifetime of severe debility and incapacitation.

Methods: This retrospective study examined the incidence, severity, predictors and likely predisposing factors for development of PTSD among 378 patients treated for craniomaxillofacial trauma at a tertiary care centre, over a five-year period. It correlated the likelihood of development of PTSD with the mode of injury sustained and analysed the management protocols employed and outcomes achieved.

Results: 31% of the patients demonstrated a positive diagnosis for PTSD and were managed for the same. Self-inflicted maxillofacial trauma patients exhibited the highest risk for developing PTSD, followed by victims of natural disasters, combat associated trauma victims (blast and ballistic injuries), followed thereafter by physical assault and RTA victims. Depending upon the severity of PTSD exhibited by the different patients, counselling, psychotherapy, and/or pharmacotherapy were employed.

Discussion: Careful screening of craniomaxillofacial trauma victims for features of PTSD cannot be overemphasized. Timely and effective management of the same can go a long way towards successful rehabilitation of these vulnerable group of patients. Surgical management of orofacial injuries should integrate case management that addresses psychosocial sequelae as it is not only necessary to restore the integrity of the anatomy and function, but also to provide psychiatric support and therapy for patients experiencing symptoms of PTSD caused by traumatic events.

Published: May 2022

Crises in therapist-patient relationship can also become a challenge in clinical supervision. However, success and failure in establishing and maintaining constructive relationships in therapy and supervision is not only subject to a lucky fit of personal characteristics (therapist A gets along well/badly with client B; supervisee A gets along well/badly with supervisor C). Rather, we can identify determining field conditions in the overall therapeutic and supervisory situation for this outcome. We do not only focus on the persons involved, but also on their environment, the task to be accomplished together, further framework conditions and the power relations resulting from their mutual influence - in the supervised case of therapy as well as in supervision itself. We want to examine the structure and dynamics of these relationships from a genuine Gestalt psychological perspective. What contributes to a cooperative atmosphere? When do goals get out of sight? What can make the atmosphere hostile? How do such developments become accessible in supervision?

Background: Advanced echocardiography using two- and three-dimensional myocardial strain proposes to identify subclinical systolic dysfunction in different clinical conditions. Strain assessment plays an important role in the early diagnosis of diabetic cardiomyopathy in diabetes mellitus (DM). However, the findings of published articles are heterogeneous. Here we conducted a systematic review to analyze the current role of strain assessment in patients with DM. Methods: This systematic review of five databases identified 19 studies that used twodimensional strain and 8 studies that used three-dimensional strain. Results: The studies of two-dimensional strain included 1,774 DM patients (mean age, 57.1 years; median age, 55 years; 47.5% women), while those of three-dimensional strain included 488 DM patients (mean age, 55.7 years; median age, 63 years; 51% women). Global longitudinal strain was the myocardial deformation marker that differed most frequently between the DM and control groups. Conclusion: Myocardial strain imaging by two- and three-dimensional speckle tracking echocardiography allows the identification of subclinical systolic dysfunction in DM patients, and differences become more marked when associated with risk factors and ventricular remodeling.

Good corporate governance can support companies in improving their performance, especially in their financial performance, by assisting in decision making, so it can be said that governance is important for companies. The implementation of good corporate governance can also increase the value of the company and increase investor confidence. Good corporate governance cannot be implemented without good internal control, where internal control supports the implementation of governance so that financial performance can be better. Internal control helps in monitoring so that corporate governance can run well in order to achieve company goals.We investigate the influence of governance on the financial performance of manufacturing companies with the support of internal control. The study was conducted using the annual reports of manufacturing companies listed on the Indonesia Stock Exchange (IDX) in 2016-2018. Moderated Regression Analysis (MRA) was using in this study. The results indicate that corporate governance is able to improve the company's financial performance, but has not been able to prove the moderator role of internal control on the influence of corporate governance on the financial performance.

It includes removing suspended solids, chemical contaminants, and toxic gases from water, wastewater, and other industrial applications. A total of 206 published documents from the Scopus database, authored by 160 scholars across 63 countries, have been analyzed using Harzing’s POP (for analyzing the citations) and VOSviewer (for constructing and visualizing bibliometric networks) program. The findings show that countries from Asia, mainly China, India, and Malaysia, dominate the publication in this field, with the Desalination and Water Treatment topping the journal list, followed by the Journal of Environmental Chemical Engineering and Science of the Total Environment. In terms of co-occurrence, the top author keywords are “agricultural wastes,” “water and wastewater treatment,” and “adsorption.” In addition, five research streams were identified, namely “biomass characterization and optimization,” “adsorbent for water and wastewater quality improvement,” “filtration by activated carbon,” “heat treatment for biochar,” and “bio-adsorbents kinetics, isotherms and thermodynamic.” Finally, the authors suggest potential research directions on filtration modeling for optimization, utilizing agricultural-based media for water and wastewater treatment.
Leaching of Electric Arc Furnace Slag for Selective Recovery of Iron: Effect of Temperature, H2SO4/HCl Acid, and Oxidant Concentration

Published: May 2022

A significant amount of electric arc furnace slag (EAFS) is generated as a by-product from the steelmaking industry. Acid leaching was carried out with both the presence and absence of oxidants to intensify the iron recovery from EAFS in the final product. Oxidative leaching refers to the process whereby the oxidant helps in removing one or more electrons in a chemical reaction. In contrast, non-oxidative leaching means there is no transfer of electrons during the process. In this study, hydrogen peroxide and potassium permanganate were used as the oxidants in the leaching process. The influences of the leaching factors, such as the concentration of leaching reagent (0.5–8 M), leaching temperature (323–363 K), EAFS particle size (50–300 μm) and concentration of the oxidants (0.5–2 M), were also studied. The findings revealed that the particle size, acid dosage and type of oxidants significantly influenced iron recovery. Smaller particle sizes greatly improved the recovery of iron. İn the non-oxidative leaching environment, sulphuric acid exhibited a higher iron recovery than hydrochloric acid. The recovery efficiency was 21.47% higher. For oxidative leaching, the leaching efficiency of iron was more favourable at lower concentrations of hydrogen peroxide in both sulphuric and hydrochloric acid, and the opposite was the case for potassium permanganate. An overdose of hydrogen peroxide can cause radical quenching, which will reduce oxidant utilisation. Oxidative leaching resulted in better iron recovery at optimum leaching conditions with a temperature of 50°C, 5 M H2SO4, 1 M hydrogen peroxide, a leaching time of 60 minutes, a solid to liquid ratio of 1:20 and a stirring rate of 300 rpm.

Heat transfer in engineering applications has shown progress, especially in electronic devices that raise the need for better heat sink designs. In addition, the generation of heat in devices and electronic circuits has also augmented, leading to the problem of heat dissipation. This study investigates the thermal and fluid flow characteristics of different geometrical configurations of pin fin heat sink under natural convection. The heat sink models studied are Hybrid Pin Fin with Connector Heat Sink (HPFWC HS) and Pin Fin with Connector Heat Sink (PFWC HS). All heat sinks models were simulated using CFD Ansys to analyse each heat sink’s thermal performances and flow fields. The results show that adding wings to the HPFWC HS significantly increased heat dissipation. In terms of heat transfer characteristics, the HPFWC HS has about a 5.78% increase in Nusselt number compared with HPFWC HS. The reason is that the heat sink HPFWC HS has wings around it, and these wings help to promote vortex formation around the fins, which leads to a higher heat transfer coefficient. A fin spacing of 15mm is the best spacing for the heat sink compared to other fin spacing.

Published: May 2022

Software fault prediction is an important activity in the testing phase of the software development life cycle and involves various statistical and machine learning techniques. These techniques are useful for making accurate predictions to improve software quality. Researchers have used different techniques on different datasets to build fault prediction in software projects, but these techniques vary and are not generalised. As a result, it creates challenges that make it difficult to choose a suitable technique for software fault prediction in a particular context or project. This mapping study focuses on research published from 1997 to 2020 involving fault prediction techniques, intending to determine a classification of fault prediction techniques based on problem types that researchers need to solve. This study conducted a systematic mapping study to structure and categorise the research evidence that has been published in fault prediction. A total of 82 papers are mapped to a classification scheme. This study identified research gaps and specific issues for practitioners, including the need to classify fault prediction techniques according to problem types and to provide a systematic way to identify suitable techniques for fault prediction models.

Published: May 2022

The development of residential areas in the trend of urbanization and the development of industrial parks and clusters have caused risks to reduce the surface water quality of the Mekong River in An Giang province. This study was conducted by sampling surface water affected by urban areas and affected by industrial parks/clusters (seven sampling points) in June 2021 and analyzing the parameters of temperature, pH, DO, TSS, COD, BOD5, N-NO3-, N-NH4+, P-PO43-, Coliform, As, Pb, Hg, Benzene hexachloride, Dieldrin. The analytical results of water samples were compared with the National Technical Regulation of Vietnam. The water quality index was calculated according to the technical guidelines of the Vietnam Environment Administration (VN_WQI). The results show that domestic and industrial wastewater has polluted the surface water of the Tien River and the Hau River, two important rivers of the downstream Mekong River, flowing through An Giang province. The pollution shows in parameters of TSS, DO, BOD5, COD, N-NH4+, and Coliform that exceeds allowable limits. However, other parameters such as temperature, pH, N-NO3-, P-PO43- are mostly at the acceptable range and within allowable limits. Based on the WQI, most of the water quality at the sampling points is poor. Therefore, it is recommended that people not directly use the Tien River and Hau River water in An Giang for drinking and domestic purposes. It is necessary to apply appropriate water treatment measures. In the coming time, authorities need to monitor and take appropriate measures to treat and manage wastewater from urban areas and industrial parks/clusters.

Published: May 2022

Job-related stress at the workplace has a tremendous effect on employees’ work performance. This study aims to evaluate the effectiveness of the Workplace Health Promotion (WHP) programme on employee sickness absenteeism, medical cost claims and work engagement among blue-collar manufacturing workers in Malaysia. The WHP intervention comprised organisational and individual stress management programmes delivered through the Occupational Stress Management Course and Employee Assistance Programme. Data on sickness absenteeism and medical cost claims were gathered from the records of the Human Resource Department. In addition, work engagement data were collected through the Malay Validated Utrecht Work Engagement Scale (UWES). Eighty-eight employees participated in the study. Most employees worked 45 hours a week, with more than 80% working overtime and shifts. Pre-intervention sickness absenteeism among manufacturing workers varied from 0.98 to 2.57 days. At baseline, medical cost claims ranged from RM92 to RM196 for three months and RM127 to RM359 for six months. After six months of participation in the WHP programme, sickness absenteeism was significantly reduced (d = 0.414) and work engagement was significantly enhanced (d = 1.958) in the intervention group. Medical cost claims, on the other hand, increased significantly post-intervention (d = 0.039). These findings are intended to help organisations and government bodies in recognising the potential of WHP to enhance employee work engagement and reduce sickness absenteeism to improve work organisation and personal development.

Published: May 2022

Background. Asthma is a complex disorder characterized by variable and recurring symptoms, airflow obstruction, bronchial hyperresponsiveness, and an underlying inflammation. Asthma is one of the most common chronic diseases in the world and its burden of disease is exceedingly high. According to current guidelines, the asthma action plan is a cornerstone in the management and control of asthma exacerbations. Written action plans are now recommended for all children with asthma as part of initial home management of acute wheezing episodes and exacerbations. Translating the written asthma action plan to Filipino and testing it for cultural content validity and reliability will make it useful on a wider scale in our country, help reduce morbidity, and improve asthma control in the Filipino pediatric population.

Objectives. To perform content and cultural validation and reliability testing of the Filipino Written Asthma Action Plan (FWAAP).

Methods. The Written Asthma Action Plan was translated to Filipino following conventional translational steps: 1) forward translation, 2) back translation, 3) pilot testing and validation, 4) final translated version. We conducted a cross-sectional study and administered the FWAAP during pilot testing among children and caregivers with asthma attending an asthma clinic.

Results. We included 31 patients. The participants considered the FWAAP to be relevant to their disease, understandable, concise and useful in the management of asthma. The tool was shown to be highly consistent (Cronbach’s alpha coefficient = 0.9235 showing that the. Seigel and Castellan’s Kappa (Inter-rater or Inter-observer consistency) showed inter-rater agreement of 0.9615 (kappa of 0.7787) and 0.923 (kappa of 0.8846) respectively showing adequate inter-rater agreement.

Conclusion. The Filipino asthma action plan is a reliable and valid tool for managing asthma in the home setting.

Published: May 2022

Background. Systemic Lupus Erythematosus (SLE) in children has been estimated to account for 15 to 20% of all SLE cases worldwide. It was described to have more severe disease at presentation including renal, neuropsychiatric, and hematologic involvements; more disease activity over time, and a significantly higher risk of organ damage. Thus, considered a significant risk factor for mortality among adult SLE patients.

Objective. This is a retrospective cohort study aimed to determine the clinical profile, outcome, and survival of SLE among Filipino children.

Methods. All SLE patients, less than 19 years old, diagnosed in the pediatric department of a tertiary hospital from January 2008 to December 2017 were included in the study. Their medical charts were retrieved for data gathering. Demographics, and clinical disease characteristics were collected from admission and on subsequent follow ups. Lost to follow up patients were contacted for updates of their current clinical status.

Results. A total of 261 pediatric SLE patients were gathered. Average age at diagnosis is 14.5 years old (±2.7), with female to male ratio of 16:1. Symptoms starts at 3 months prior to consult (±2.1). Upon diagnosis, most of the patients have fever, malar rash, alopecia, oral ulcers, and proteinuria. Most common systemic organ involvement through time were mucocutaneous, hematologic, and renal. Steroids were the mainstay management for all patients, in which 95% started on oral Prednisone, while 71% needed IV Methylprednisolone in at least once during the disease course. Two patients received biologic treatment. Overall mortality rate was 14.9%, identified to be secondary to sepsis and/or SLE activity. Myocarditis, pleural effusion, and seizures were identified as significant risk factors for mortality. Survival rate at 1 year and 10 years were 92% and 79%, respectively.

Conclusion. SLE in Filipino children mostly presents with mucocutaneous symptoms. Presence of seizures, myocarditis, and pleural effusion at any time of the disease entails risk for mortality. SLE nephritis is a substantial cause of morbidity due to its chronicity. The survival rate of Filipino children with SLE is comparable with the data from other developing countries.

Published: May 2022

Objective. To determine factors predictive of obstructive neonatal cholestasis among Filipino infants and to describe their outcome.

Methods. Jaundiced infants within the first eight weeks of life with liver biopsy were included. Excluded were cholestasis secondary to metabolic or infective causes. Retrospective chart review (2009-2012) and prospective recruitment of patients (2013) were done. A final diagnosis of non-obstructive or obstructive neonatal cholestasis was made on clinical, biochemical, ultrasonographic, and histologic findings, using histology and/or operative cholangiogram as the gold standard. The outcome was assessed on the 6th and 12th months from diagnosis. The crude odds ratio for obstructive jaundice was computed. Multiple logistic regression on significant variables (p-value <0.05) was done.

Results. Two hundred sixty-three (263) patients were included: 161 with non-obstructive and 102 with obstructive cause. Mean age at first consult was higher in those with obstruction. On logistic regression, females (OR:2.3), absence of a family history of idiopathic neonatal hepatitis (OR:4), and persistently pale/acholic stools (OR:13) were predictive of obstruction. 85% of patients with a non-obstructive cause are alive and well, while 80% of patients with obstruction have died.

Conclusion. Among jaundiced infants females, the absence of a family history of idiopathic neonatal hepatitis and persistently pale yellow/acholic stools were predictive of obstruction. The outcome was poor in patients with obstructive jaundice.

Authors: Nyachomba Judy , Achuora John
Published: May 2022

Purpose: This study aimed to assess the determinants of green supply chain management practices on the performance of gas manufacturing companies in Kenya.

Methodology: This research study adopted a descriptive research design approach. The researcher prefers this method because it allows an in-depth study of the subject. There are twenty-eight (28) gas manufacturing firms in Kenya according to the Petroleum Institute of East Africa (PIEA) directory in 2021. The unit of analysis was the individual gas manufacturing firms. The unit of observation was five (5) procurement officers from each of the twenty-eight (28) gas manufacturing firms in Kenya. The total number of respondents was one hundred and forty (140). The study in its data collection used questionnaires. After data collection, quantitative data was coded using Statistical Package for Social Science (SPSS) version 20. Data were analyzed through descriptive statistical methods such as means, standard deviation, frequencies, and percentages. Inferential analyses were used in relation to correlation analysis and regression analysis to test the relationship between the four explanatory variables and the explained variable. Results were presented using tables, graphs, and charts

Results and conclusion: The response rate of the study was 85%. The independent variables reported-value of .775 indicating that there isa perfect relationship between the dependent variable and independent variables. R square value of 0.6   means that 60% of the corresponding variation in performance of gas manufacturing firms can be explained or predicted by green product design, green distribution, green warehousing and reverse logistics, which indicated that the model fitted the study data.

The findings of the study indicated that green product design, green distribution, green warehousing,g, and reverse logistics have a positive relationship with performance in gas manufacturing firms

Policy recommendation: The study recommended that gas manufacturing firms should embrace green supply chain management practices so as to improve performance and furtherresearchs should be carried out in other institutions to find out if the same results can be obtained.
Inteligência artificial no apoio à solução consensual no Poder Judiciário brasileiro

Published: May 2022

Desde 2020, o Centro de Inovação, Administração e Pesquisa do Poder Judiciário da Fundação Getulio Vargas (CIAPJ FGV) acompanha a implementação da inteligência artificial (IA) nos tribunais brasileiros a partir do mapeamento das iniciativas no Conselho Nacional de Justiça (CNJ), no Supremo Tribunal Federal, no Superior Tribunal de Justiça, no Tribunal Superior do Trabalho, nos Tribunais Regionais do Trabalho, nos Tribunais Regionais Federais e nos Tribunais de Justiça. Pelo fato de ser um levantamento bastante dinâmico, uma atualização dos dados foi realizada em 2021. A pesquisa tem natureza exploratória e descritiva e as informações foram levantadas por meio de formulário enviado aos tribunais. Uma análise preliminar dos resultados identificou 54 iniciativas que utilizam IA e um número expressivo desse conjunto (47) é voltado à automação de atividades jurisdicionais. O estudo encontrou duas iniciativas de IA diretamente relacionadas ao índice de conciliabilidade, ambas no âmbito da Justiça do Trabalho. A primeira é o Concilia JT, desenvolvido pelo Tribunal Regional do Trabalho da 12ª Região, o qual tem a finalidade de predição do potencial de acordo dos processos a serem encaminhados à conciliação no tribunal. A segunda é o Índice de Conciliabilidade por Inteligência Artificial (ICIA) que foi desenvolvido pelo Tribunal Regional do Trabalho da 4ª Região para estimar o sucesso da conciliação a partir de informações como o histórico de conciliação das partes, tipos de conflito, perícias realizadas no âmbito do processo, dentre outras. O Relatório Justiça em Números do CNJ, particularmente a edição de 2021, aponta para uma tendência de declínio do índice de conciliação nos dois últimos anos. Diante desse quadro, cabe acompanhar se a IA se confirma como um elemento importante para impulsionar e melhor direcionar os processos para os meios consensuais.
Big Data: a privacidade dos dados em risco
Authors: Cardoso Andressa Alonso de Oliveira
Published: May 2022

Durante a última década, duas grandes evoluções estruturais se cruzaram: a propagação da vigilância diária e a expansão do "big data". Nessa esfera, houve um aumento na análise computacional e vários conjuntos de dados conhecidos como "big data"; o uso de big data em atividades de vigilância policial tem sido objeto de debates na política, na mídia, na regulamentação legal e na academia. No entanto, o discurso sobre o assunto é em grande parte especulativo e foca na possibilidade de monitorar novos tipos de bancos de dados: os bons e os ruins. Desse modo, surge um questionamento sobre a proteção destes dados, pois a inovação criminosa avança de forma rápida, tendo em vista que o big data pode ser utilizado por agências de aplicação da lei que buscam prevenir e interromper ações criminosas, ele também pode ser valioso para os criminosos, permitindo-lhes cometer crimes cibernéticos mais rebuscados. O objetivo do trabalho busca analisar as vulnerabilidades dos dados no big data que podem ser alvo de cibercriminosos. O trabalho consiste em uma pesquisa qualitativa com base no método hipotético-dedutivo, com procedimento bibliográfico e documental. Com o número crescente de dispositivos conectados sem fio, existem oportunidades para hackers e criminosos fraudulentos interceptarem e coletarem dados pessoais. As informações biométricas, como as informações usadas na tecnologia de identificação, estão se tornando mais acessíveis para coletar e processar a grupos e indivíduos do crime organizado. Desta maneira, conclui-se que deve haver garantia que medidas de segurança suficientes estão em vigor para evitar que dados e tecnologias de aplicação da lei desenvolvidas para agências de serviço público estejam à disposição de criminosos.
Interdisciplinary Data-integrated Approaches
Authors: Hensel Michael , Bier Henriette
Published: May 2022

Rapid urbanization with the associated land cover and land use change, as well as resource depletion, contribute to the degradation of ecosystems and biodiversity and have a negative impact on human health and well-being. Societal calls for responses and results pose a significant challenge for research and education in the various fields concerned with the environment. Alongside the current environmental crisis there is a pressing need for developing ‘green solutions’ for the built environment with the help of datadriven methods, workflows and tools.

In view these developments, a shift from narrow disciplinary and domain-specific approaches towards broader interdisciplinary, multi-domain and multi-scalar strategies is required. This includes dataacquisition, data-sharing and data-integration, as well as data-driven modelling to enable the complexity of sustainability problems arising from rapid urbanization to be tackled. While there have been efforts to address the challenges of multi-domain approaches, for instance in the fields of sustainability, the urban and architectural sciences, as well as the interoperability of methods and tools, the actual problem goes deeper, requiring interdisciplinary knowledge exchange to develop adequate shared paradigms, concepts, methods and tools.

Cyber-physical Architecture (CpA) issue 5 addresses these challenges by engaging with experts from a range of disciplines involved in environmental concerns while utilizing data-acquisition, data-sharing and integration, and data-driven modelling in a discourse that identifies modalities for a broader interdisciplinary, multi-domain and multi-scalar approach.
