Authors: Kalphana Dr. K. R.
Published: June 2022

Abstract: In dairy products, cheese is one of the main products consumed by all human beings all over the world. During manufacturing, proper management and maintenance are mandatory to produce quality cheese for human use. This could be achieved through proper monitoring by human resources. Hence manpower consumption is high and mishandling takes place which affects the quality of cheese production. This proposed system by utilizing sensors and its advantages leads to the cheese quality monitoring process. Temperature, gas and humidity sensors are used to monitor the cheese storing environment; these details are easily viewed through an RFID tag. Through this tag cheese, the current environment status is monitored easily and if any change in the temperature, carbon dioxide and humidity will be intimated through a buzzer. Therefore proposed system supports heavily maintaining cheese quality and monitoring its process in an efficient way with less human resource consumption.

Authors: Sujini G Naga
Published: June 2022

Abstract: Deep learning is an important element of data science, which includes statistics and predictive modeling. It is extremely beneficial to data scientists who are tasked with collecting, analyzing and interpreting large amounts of data. It makes this process faster and easier. We present a deep learning system for automatic logo detection in real world images. We base our detector on the popular framework of Faster R-CNNand compare its performance to other models such as Mask R-CNN or RetinaNet. We perform a detailed empirical analysis of various design and architecture choices and show how these can have much higher influence than algorithmic tweaks or popular techniques such as data augmentation. We also provide a systematic detection performance comparison of various models on multiple popular datasets including FlickrLogos-32, TopLogo-10 and recently introduced QMUL-OpenLogo benchmark, which allows for a direct comparison between recently proposed extensions. By careful optimization of the training procedure we were able to achieve significant improvements of the state of the art on all mentioned datasets. We apply our observations to build a detector to detect logos of the Red Bull brand in online media and images. Automatic logo detection and recognition is a challenging computer vision task with many applications. One of the typical purposes of such systems is measurement of brand visibility and prominence in online media or television broadcasts.

Published: June 2022

We report a case of a 14-year-old Korean boy presenting with pain in the left lower quadrant, persisting for over 10 days. Except for the persistent pain, no other symptoms, such as vomiting and diarrhea, were observed. In addition, laboratory findings were normal. He was eventually diagnosed with epiploic appendagitis, a rare disease in children. This case highlights the need for imaging study for early diagnosis of epiploic appendagitis or surgical emergencies in children who visit emergency departments with pain in the left lower quadrant without specific clinical findings.

Published: June 2022

Selection on quantitative traits by divergent climatic conditions can
lead to substantial trait variation across a species range. In the
context of rapidly changing environments, however, it is equally
important to understand selection on trait plasticity. To evaluate the
role of selection in driving divergences in traits and their associated
plasticity within a widespread species, we compared molecular and
quantitative trait variation in Populus fremontii (Fremont cottonwood)
populations throughout Arizona. Using SNP data and genotypes from 16
populations reciprocally planted in three common gardens, we first
performed QST-FST analyses to detect selection on traits and trait
plasticity. We then explored the mechanistic basis of selection using
trait-climate and plasticity-climate regressions. Three major findings
emerged: 1) There was significant genetic variation in traits expressed
in each of the common gardens and in the phenotypic plasticity of traits
across gardens. 2) Based on QST-FST comparisons, there was evidence of
selection in all traits measured; however, this result varied from no
effect in one garden to highly significant in another, indicating that
detection of past selection is environmentally dependent. We also found
strong evidence of divergent selection on plasticity across environments
for two traits. 3) Traits and/or their plasticity were often correlated
with population source climate (R2 up to 0.77 and 0.66, respectively).
This suggests that steep climate gradients across the Southwest have
played a major role in shaping the evolution of divergent phenotypic
responses in populations and genotypes now experiencing climate change.
Microstructuring Process in Oleogels Formulated with Vegetable Oils and Monoglycerides: A Comparison of Non-Isothermal Nucleation Kinetics by Spectrophotometric and DSC Analysis
Authors: Contreras-Ramírez Javier Isaac , Acosta-Gurrola Esperanza , Rosas-Flores Walfred , Gallegos-Infante Jose Alberto , Toro-Vazquez Jorge
Published: June 2022

The initial oleogelation process (microstructuring) as well as the
formulation are determinant to obtain the desired characteristics in
oleogels with potential application in the industry. The
microstructuring process in oleogels has been extensively studied by
means of techniques highly sensitive to thermal variations, such as
differential scanning calorimetry (DSC). However, there are other
readily available techniques and equipment that can be employed to
perform similar evaluations. Non-isothermal nucleation kinetics by
spectrophotometric methods can be used as alternatives to basic
crystallization studies in oleogels. Therefore, in this research a
comparison of both techniques is presented, highlighting their
similarities, advantages and limitations, in the study of the
microstructure of oleogels. Oleogels were obtained with a minimum
concentration of gelator and another saturated one, using vegetable oils
of different degrees of saturation. The crystallization profiles of the
oleogels were obtained by DSC, a non-isothermal nucleation kinetics was
performed from the molten system and the final microstructure was
evaluated by optical microscopy. The Fisher-Turnbull and Avrami model
was used to evaluate the behavior during microstructuring. A gap was
observed during the crystallization process by DSC which can be
evaluated by spectrophotometry. Differences in the microstructuring
process were found in both methods due to the temperature ramp used and
formulation variables. The results obtained by spectrophotometry
indicate that it can be a good alternative, easily accessible in oleogel
crystallization studies, when high sensitivity or very specific thermal
parameters are not required.

Los resultados indican que la media no mostró diferencias estadísticamente significativas y se mantuvo la ansiedad escolar en estos niños en el periodo de tres años. Se apoyó la posibilidad de que se presente como un síntoma estable de los estudiantes, más que responder a eventos puntuales del entorno.
Representing the absent: The limits and possibilities of digital memory and preservation
Authors: Antonijevic Smiljana , Ubois Jeff
Published: June 2022

Digital preservation has significantly expanded over the past few decades,
renewing old and creating new challenges related to provenance, integrity,
completeness, and context in memory and preservation practices. In this
paper we explore how, perhaps counterintuitively, a more extensive digital
historical record offers greater opportunities to misrepresent reality. We
first review a set of concepts and socio-cultural approaches to memory and
preservation. We then focus on the multiplicity of digital memory and
preservation practices today, examining their limits, possibilities, and
tensions; specifically, we explore the challenges of decontextualized data,
personal versus institutional preservation, and ?outsider? digital
collections that are willingly and/or forcibly excluded from official
accounts. Through these discussions, we review examples of what we consider
good digital memory and preservation practices that take new approaches to
context and collaboration. Lastly, we explore the optimism inherent in
seeking to preserve human knowledge over the long term and to make it
accessible to all.
Between history and system. Heinrich Rickert’s concept of culture
Authors: Morrone Giovanni
Published: June 2022

The paper reconstructs the concept of culture that emerges from Heinrich
Rickert?s neo-Kantianism, uncovering its major historical-problematic,
methodological, and philosophical implications. The central theme of the
first section is the idea that modern culture is uniquely characterized by
?fragmentation?. It also unpacks the programme of Rickert?s philosophy of
culture, which pursues the task of reconstructing the lost unity of culture.
The second section explains the methodological implications of the
problematic relationship between value and reality established in cultural
goods and evaluations. Finally, the third section reconstructs the
Rickertian system of values, with its peculiar effort to reconcile
historicity and value absoluteness. The last part develops a critical
discussion of the Rickertian project.

Authors: YİLMAZ Ummihan , PEHLİVANLI Burak , ERKAN Ayşe , KILIÇLI Volkan
Published: June 2022

AISI 4140 çeliği, orta karbonlu düşük alaşımlı çelikler sınıfında yer almakta olup, yüksek sertleşebilirliğe sahip olması ve nispeten ekonomik bir çelik olması nedeniyle endüstride yaygın olarak kullanılmaktadır. AISI 4140 çeliği aynı zamanda nitrürlebilen çelikler arasında yer almaktadır. Nitrürleme işlemiyle, yüzeyde elde edilen sert nitrür tabakası sayesinde sadece aşınmaya dirençli bir yüzey değil aynı zamanda yorulma dayanımında da artış sağlanmaktadır. Bu çalışmada, düşük basınçlı gaz nitrokarbürleme işlemi ve farklı sürelerde son oksidasyon işlemi uygulanmış AISI 4140 çeliğinin mikroyapısal ve yüzey özellikleri araştırılmıştır. Bu amaçla, AISI 4140 çelik numuneler, 850 °C'de 60 dk östenitlenmiş 60 °C’de yağda soğutulmuştur. Soğutma sonrası numuneler 630 °C’de 60 dk temperlenmiştir. Gaz nitrokarbürleme işlem basamakları; 350 °C’de 45 dk ön oksidasyon, 550 °C’de 90 dk nitrürleme ve 550°C’de 480 dk nitrokarbürleme uygulanmış ve ardından numuneler 45-180 dakika aralığında su buharı kullanılarak son oksidasyon işlemine tabi tutulmuştur. Mikroyapısal karakterizasyon çalışmaları optik mikroskop, tarama elektron mikroskobu (SEM), enerji dağılımlı X ışını spektrum analizi (EDX), X ışını kırınımı (XRD) analizi, mikrosertlik ve yüzey pürüzlülüğü ölçümleriyle gerçekleştirildi. X ışını analiz sonuçlarından, numunelerin yüzey katmanının demir nitrür, ɛ-Fe2-3N ve ɣ’-Fe4N fazlarını ve demir oksit (Fe3O4) içerdiği tespit edilmiştir. Son oksidasyon süresi arttıkça, demir oksit (Fe3O4) tabaka kalınlığını arttığı belirlendi. Nitrokarbürlenmiş ve son oksidasyon işlemi uygulanmış AISI 4140 çelik numuneler içerisinde, en iyi sertlik derinliği, yüzey sertliği ve yüzey pürüzlülüğü birleşimi 150 dakikada son oksidasyon uygulanmış elde edilmiştir.
Laser engineering of ITO/ZnO/ITO structures for photodetector applications

Published: June 2022

ZnO nanomaterials have received much attention due to their suitability for applications such as gas sensors, UV detectors, and solar collectors. However, the functionality of ZnO in optical applications is often limited by its wide bandgap (3.15 eV) which restricts the response to shorter wavelengths. In view of this limitation, there has been much interest in tuning the optical properties of ZnO through defect engineering. In this work, we show that processing ZnO thin films with nanosecond (ns) laser irradiation is a simple and effective way to introduce interband defects lowering the bandgap and increasing the sensitivity of ITO/ZnO/ITO photodetector structures at longer wavelengths. In particular, we show that the concentration of oxygen vacancies in ZnO is proportional to laser fluence below 700 mJ/cm2, but that an increase in laser fluence above this value results in thermal heating that anneals the film and lowers the relative abundance of oxygen vacancies. On the other hand, the surface morphology of ZnO does not change significantly even though the fluence reaches 700 mJ/cm2. To illustrate the way in which laser processing can be utilized to improve the optical properties of ZnO films in photodetector applications, we have fabricated transparent ITO/ZnO/ITO stacked structures and measured their response at various optical wavelengths. We find that processing with ns laser radiation is effective in enhancing the responsivity and detectivity of these devices at blue (460 nm) and UV (390 nm) wavelengths. The response of the photodetector is also increased at green wavelengths (570 nm) and red wavelengths (620 nm) when processed with laser fluences in the 480–600 mJ/cm2 range.

Published: June 2022

As the Earth’s changing climate has deepened into a climate crisis, the Arctic region has emerged as one of the clearest indicators of the scale and pace of that change. As the ice melts, opportunities are expanding to exploit the Arctic’s oil and gas reserves, precious metals, fish stocks and maritime routes. Increased access and development will inevitably generate “system-wide environmental impacts” and will pose novel management challenges for the Arctic states. In the quest to find an effective balance between competing ocean activities and actors, marine protected areas (MPAs) and other effective area-based conservation measures (OECMs) have emerged as indispensable tools to achieve ocean health, including in the Arctic. After first introducing these concepts, this article will discuss the Canadian and Russian domestic regimes for the establishment of MPAs and OECMs. The conclusion will then offer some insights into the key challenges confronting both states in the creation of effective networks of MPAs and OECMs in their Arctic regions.

Depopulation of Ukraine
Authors: Coleman David
Published: June 2022

Blessed by its geology but a prisoner of its geography, the inhabitants of Ukraine have suffered repeated destructive depopulation. The population loss in the Ukraine 1914–21 was over five million. The second modern depopulation culminated in 1932 during Stalin’s manmade famine, with estimated total population losses of 4.6 million people. A third depopulation followed as over 7 million Ukrainians lost their lives in the Second World War.
Between the censuses of 1959 and 1970 population of Ukraine recovered briskly. Total fertility remained at about replacement level until the end of the Soviet Union, then declined. A relatively strong recovery of fertility was reversed in 2012, presumably as a consequence of the Russian invasion in Eastern Ukraine, and total fertility dropped to 1.2.
The population in early 2022 was around 37 million. The Ukrainian global diaspora is one of the most widely-distributed populations in the world, with 6.1 million Ukrainians living abroad already in 2020. After Russia’s invasion in February 2022 thousands have died and millions have been forced to flee. The article ends by considering how Ukraine’s demographic situation might evolve in the future.
This issue of the Yearbook was finalised after Russia attacked Ukraine the 24th of February, 2022. In this invited reflection, professor David Coleman provides an overview of Ukraine’s demographic history and previous challenges. (Editor’s note)

Authors: Tymofieiev Oleksii , Ripa Viktoriia , Havlytiuk Diana , Sokoliuk Marta , Kolisnichenko Lesia
Published: June 2022

Purpose: Currently, dental prosthetics on endosseous implants is used in most dental clinics of Ukraine. The incidence of inflammatory complications after the surgical stage of dental implantation, according to different authors, ranges from 0.4 to 5 percent. Therefore, many doctors during the surgical stage of dental implantation are looking for medications that simultaneously have both anti-inflammatory and analgesic effects. The purpose of this study is to determine the effectiveness of the treatment of early post-implantation complications when using the drug “Trachisan®” and compare its effectiveness with the traditionally used therapy.
Materials and Methods: According to our observation, there were 24 patients aged from 20 to 56 years (1st observation group or main group). We prescribed Trachisan to these patients in the post-implantation period for 4 days. The control group consisted of 30 patients (2nd observation group or the control group), who were treated with traditional methods in the post-implantation period (Analgin tablets [metamizole sodium] and conventional antiseptic rinses).
Results: Inflammatory complications in the 1st (main) group were not detected, and in the 2nd (control) group, inflammatory complications were diagnosed in 7 patients (23.3 percent), namely: mucositis – in 4 patients (13.3 percent) and peri-implantitis – in 3 patients (10 percent).
Conclusions: Thus, the drug “Trachisan” should be recommended for widespread use in maxillofacial surgery after the surgical stage of dental implantation to prevent post-implantation inflammatory complications.

Í greininni er fengist við tvær rannsóknarspurningar, annars vegar hvort hægt sé að nota gögn úr mælingum á fyrirtækjamenningu þar sem mælitæki kennt við Denison (DOC‘s) er notað til að leggja mat á þjónustuáherslu, og hins vegar hvaða tengsl séu á milli þjónustuáherslu og árangurs. Gögnin sem notuð eru byggja á sjálfstæðum rannsóknum sem unnar hafa verið í samstarfi við fyrirtæki og stofnanir sl. 15 ár en í gagnagrunninum liggja fyrir mælingar frá 68 skipulagsheildum og er heildarfjöldi svara, þegar þessi rannsókn er gerð, 6.039. Í þessari rannsókn er stuðst við gögn frá níu fyrirtækjum þar sem gagnaöflun átti sér stað árin 2019 og 2020. Gögnin voru sett í einn gagnagrun og eftir hreinsum þeirra stóðu eftir 875 gild svör. Niðurstöður sýna að 23 spurningar úr DOC‘s náðu yfir 30 af 35 spurningum úr SERV*OR en það mælitæki hefur verið sérhannað í þeim tilgangi að leggja mat á þjónustuáherslu og er haft til viðmiðunar hér. Greiningar sýndu að mat á innri áreiðanleika var gott (α = 0,94), margar spurningarnar höfðu fylgni sín á milli sem var hærri en 0,3 og engar höfðu fylgni sín á milli sem var hærri en 0,7. Þá sýndu niðurstöður að þjónustuáhersla sem byggir á DOC‘s útskýrir 47% af breytileikanum í árangri sem meðaltal af þeim sex árangursþáttum sem notaðir eru í DOC‘s. Sterkust eru tengslin við árangursþættina starfsánægju (R2 = 0,40; β = 0,64) og heildarframmistöðu (R2 = 0,40; β = 0,63) en veikust við hagnað/afkomu (R2 = 0,14; β = 0,37). Helstu takmarkanir rannsóknarinnar eru þær að gögnin koma frá fyrirtækjum sem öll hafa skarað fram úr á sínu sviði og fengið margvíslega viðurkenningar fyrir árangur í starfi. Niðurstöðurnar segja því lítið um tengsl þjónustuáherslu við frammistöðu hjá fyrirtækjum sem standa sig síður og eða eru með veikari menningu. Frekari rannsóknir snúa þá að því að skoða slíkan samanburð sem og að greina betur þau sterku tengsl sem eru á milli þjónustuáherslu og starfsánægju.
Áhrif kynjakvóta á stjórnarbrag að mati stjórnarmanna

Published: June 2022

Ísland er eitt þeirra landa sem hefur lögleitt kynjakvóta í stjórnir fyrirtækja. Áhrif þessarar lagasetningar, sem í fræðunum kallast „hörð leið“, hafa takmarkað verið rannsökuð. Við lagasetninguna var tekist á um hvort kynjakvóti í stjórnum fyrirtækja myndi leiða til breyttra stjórnarhátta og hafa áhrif á samkeppnishæfni fyrirtækja. Þessi rannsókn hefur að markmiði að afla þekkingar á viðhorfi stjórnarmanna til upptöku kynjakvóta í stjórnum og viðhorfa þeirra til þess hver fyrstu áhrif á stjórnarbrag eru. Greind eru viðhorf stjórnarmanna til þess hvort stjórnarhættir og ákvarðanataka stjórna hafi breyst með tilkomu kynjakvóta og hvort stjórnir sinni aðhalds- og eftirlitshlutverki sínu með öðrum hætti en áður. Mælingar sem greint er frá í þessari rannsókn fóru fram árið 2014, einu ári eftir að lögin tóku að fullu gildi, og gefa því til kynna fyrstu áhrif lagasetningar að mati stjórnarmanna. Alls svöruðu 244 stjórnarmenn rafrænum spurningalista, 41% svarenda var kvenkyns. Niðurstaða rannsóknarinnar varpar ljósi á að karlkyns stjórnarmenn voru neikvæðari gagnvart kynjakvóta í stjórnum þegar lögin voru upphaflega samþykkt en dregið hafði úr þeim kynjamun þegar lögin höfðu tekið gildi. Niðurstöður sýna jafnframt að skömmu eftir lagasetninguna töldu stjórnarmenn almennt að kynjakvótinn hefði leitt til fjölbreyttari skoðanaskipta við stjórnarborðið og að ferlið við ákvarðanatöku stjórna sé betra en áður. Ofantalið var marktækt fremur skoðun stjórnarformanna, kvenkyns stjórnarmeðlima og þeirra sem jákvæðari voru gagnvart löggjöfinni um kynjakvóta þegar hún var upphaflega sett. Niðurstöður sýna jafnframt að stjórnarmenn telja að betri stjórnarhættir séu stundaðir eftir innleiðingu laganna. Niðurstöður sýna marktækan mun á skoðunum almennra stjórnarmanna til laganna annars vegar og formanna stjórna hins vegar þegar kemur að eftirlitshlutverki stjórna. Jafnframt eru kvenkyns stjórnarmenn ávallt marktækt jákvæðari í viðhorfum sínum gagnvart breytingum í kjölfar kynjakvóta í stjórnum fyrirtækja en karlkyns stjórnarmenn.

Published: June 2022

This research is a type of literature research that aims to examine whether regulations regarding the Income Tax of construction business need to be updated according to various dynamics that occur, including other related regulatory changes. Because there are several arrangements on Income Tax of construction business which tend to be inconsistent and overlapping. The research results indicate that it is necessary to revise the Income Tax regulation for construction services business with several recommendations, namely: (i) the limit for taxpayers who may be subject to Income Tax calculation based on Regulation of The Government Number 23 of 2018 is reduced from Rp.4,800,000,000.00 to Rp.2,500,000,000.00; (ii) the Income Tax Law for construction business in article 23 paragraph (1) letter c. number 2. of the Income Tax Law is abolished, in order to avoid double regulation; (iii) construction business with small qualifications should be subject to Income Tax Law based on Regulation of The Government Number 23 of 2018. Imposition of Income Tax based on Regulation of The Government Number 51 of 2008 which was last amended by Regulation of The Government Number 9 of 2022 only applies to construction business with medium and big qualifications.

Model of a minimal risk portfolio under hybrid uncertainty
Authors: Yazenin Alexander V. , Soldatenko Ilia S.
Published: June 2022

The article is devoted to the development and study of a model of a minimal risk portfolio under conditions of hybrid uncertainty of possibilistic-probabilistic type. In this model, the interaction of fuzzy parameters is described by both the strongest and the weakest triangular norms. The formula for variance of a portfolio is given that allows for estimating its risk. Models of acceptable portfolios are based on the principle of expected possibility or on the basis of fulfilling the restriction on the possibility/necessity and probability of the level of portfolio return that is acceptable to an investor. Equivalent deterministic analogues of the models are constructed and their solution methods are developed. Theorems describing a set of investment opportunities are proven. The obtained results are demonstrated on a model example.
An ant algorithm for the maximum number of 3-cliques in 3-partite graphs
Authors: Schiff Krzysztof
Published: June 2022

The problem of finding the maximum number of d-vertices cliques (d = 3) in d-partite graph (d = 3) when graph density q is lower than 1 is an important problem in combinatorial optimization and it is one of many NP-complete problems. For this problem a meta-heuristic algorithm has been developed, namely an ant colony optimization algorithm. In this paper a new development of this ant algorithm and experimental results are presented. The problem of finding the maximum number of 3-vertices cliques can be encountered in computer image analysis, computer vision applications, automation and robotic vision systems. The optimal solution of this problem boils down to finding a set of 3-vertices cliques in a 3-partite graph and this set should have cardinality as high as possible. The elaborated ant colony algorithm can be easily modified for d-dimensional problems, that is for finding the maximum number of d-vertices cliques in a d-partite graph.
Fasting in mood disorders and its potential therapeutic aspects -narrative review
Authors: Halczuk Izabela , Nowak Katarzyna , Chiriboga Sylvia , Rog Joanna
Published: June 2022

Introduction: Fasting is defined as a period of voluntary abstinence from eating food for religious, therapeutic or political reasons, which is associated with a reduction in the supply of sources (kilocalories) to the body. There are different types of fasting, including short, long or intermittent fasting. It has been shown that the use of different types of fasting can influence the occurrence of mood disorders. The aim of this review was to search for the relationship between the use of fasting and mood disorders and its potential use as a therapeutic method.

Material and method: The available literature was reviewed by searching the PubMed and Google Scholar databases using the following keywords: fasting, intermittent fasting, mood disorders, depression, Ramadan, for studies listed from database inception to November 2021.

Results: A review of the collected scientific articles indicates that the dietary restrictions, including both daily restriction of caloric consumption and the use of intermittent fasting (IF), has potentially numerous health benefits in the co-treatment of mental diseases. However, due to conflicting results, further clinical trials in mentally ill people should be conducted. It is worth remembering that among patients with mental illnesses there are somatically ill. IF in these people may require additional nutritional modifications or discontinuation of therapy.

Conclusions: Dietary restriction and fasting are promising methods in co-therapy of mood disorders treatment. However, implementing therapy needs earlier individual evaluation of their benefits and risk, the same as patient’s feasibility of implementing this type of intervention.
Smart City Readiness in South African Municipalities: A Qualitative Study
Authors: Enwereji Prince Chukwuneme , Uwizeyimana Dominique
Published: June 2022

This study investigated the meaning of a smart city concept, the limitations of municipal role players to adopt the smart city, and the recommendations to facilitate the adoption of a smart city concept in the municipalities of the North West province. A qualitative research approach was adopted to collect data from the participants, which facilitated adequate interactions with the participants through open-ended interviews. Twenty participants were selected purposively to participate in this study through an online platform. Data were analysed using Atlas-ti software (version 8.2), themes and categories were generated and discussed. Findings from the study depict that a smart city concept entails a city that enables communication using advanced technology, big data, the Internet of Things (IoT), and the Industrial Internet of Things (IIoT). Findings further revealed that the limitation of achieving a smart city in South African municipalities includes a lack of financial resources, inadequate infrastructure, delays in the decision-making process, lack of strategic leadership, corruption of role players, inability to implement research outcomes, and lack of investors. The study recommended, inter alia, that the municipal leadership should encourage techno-centric governance, a source for external funding, engage knowledgeable strategic leaders, facilitate public education, and SMME ICT inclusive strategy.
