Authors: Onuh Willington , Legaspi Olivia M. , Mostajo Susan T. , Malabanan Don S. , Reyes Rosario T.
Published: August 2022

Many published papers provide insights on factors affecting learning performance; however, they do not address how internet connectivity affects students’ capacity to meet assessment and learning expectations. To address this gap in the literature, we draw from a survey of 257 students at the undergraduate level to investigate two questions: (a) To what extent does internet connectivity affect missed assessments? and (b) How do students vary through the distribution of missed assessments? We used a count data model, specifically, negative binomial (NB) regression, to determine incidence rate ratios and odds of missed assessments. The NB results showed that students who indicated poor internet connectivity during the semester had about a five times higher incidence rate of missed assessments than students who did not indicate poor internet connectivity. Surprisingly, despite two-thirds of students reporting poor internet connectivity, the chance of accumulating seven missed assessments during the semester was very minimal. The results may provide insights to faculty and education policymakers at the institutional level on ways to design online learning to meet learning expectations.
The Need for Digital Education in the Teaching Profession: A Path Toward Using the European Digital Competence Framework in Albania
Authors: Miço Heliona , Cungu Jonida Cungu
Published: August 2022

Digital competence is part of 21st Century skills that allow individual teaching professionals to engage in new and flexible ways of learning. Studies have shown that digital competence improves education and equips the teaching staff with expertise on how to use information, communication, and basic problem-solving. The need for digital competence is clearly evident in the current pandemic situation, where digital technologies have taken a more prominent role in communication and education processes. Beyond the digital competence of educators, proper school infrastructure and curricula are needed during pre-service training to help teachers achieve digital competence. To better understand this need, an online survey was developed to analyze digital education in Albania. The survey was designed to analyze the teaching competence of teachers in pre-service and in-service programs, as well as their schools’ curricula and infrastructure. Results from the questionnaire highlighted a need for the acquisition of digital knowledge for teachers according to different age groups. The results of the study found that difficulties teachers encountered in the acquisition of digital knowledge were not only due to deficiencies in teacher training but also other issues such as lack of infrastructure. The study concludes by recommending that providing digital education should be in line with European and national policy and legislation, as well as with national and international organizations. The paper reports findings assessing the level of preparedness of Albanian educators in regard to digital education and explores opportunities and identifies challenges for coping with enhancing digital development.
A Comprehensive Community of Inquiry Framework for Exploring Technology Enhanced Language Learning
Authors: Alvi Irum
Published: August 2022

The use of technology for second language (L2) acquisition has become ubiquitous, but little thought has been given to the factors that impact the language learning experience. This study aims to use the Community of Inquiry (CoI) framework to propose and validate a more comprehensive model for investigating the influence of presence on learners’ L2 learning experience using Technology Enhanced Language Learning (TELL). Data were collected from a sample of language learners (n = 129) studying in the State of Rajasthan, India using an e-questionnaire. To scrutinize the effect of various forms of presence, descriptive and inferential analyses were conducted. The findings suggest strong, positive, and statistically significant associations exist between the original CoI elements (teaching presence, cognitive presence and social presence), the newly added elements (learning presence, emotional presence, and technological presence), and learning experience. These results confirm the idea that presence can hinder and/or enhance L2 learning experiences. No association was found between technical barriers and learning experience. The findings have theoretical and practical implications. The results suggest the value of expanding the CoI framework, scrutinizing the learners’ experience, analyzing the influence of presence, and enriching the application of the technology for language learning. Such results may ensure TELL courses are designed as vigorous learning environs which facilitate language acquisition.
Iterative methods of order four and five for solving non-linear system : A study on local convergence
Authors: John Jinny , Jayaraman Jayakumar
Published: August 2022

In this paper, we develop the local convergence analysis of Newton-like
fourth and fifth order iterative methods for solving a system of
non-linear equations. Earlier studies as in Petkovic (Multipoint methods
for solving nonlinear equations, Elsevier, Amsterdam,2013), Traub
(Iterative methods for the solution of equations, AMS Chelsea
Publishing, Providence, 1982) and Kalyanasundaram et al (International
Journal of Applied and Computational Mathematics 3 3:2213-2230, 2017)
shows that the local convergence was proved using Taylor series
expansion which involved the computation of derivatives of order higher
than one. For the fourth and fifth order iterative methods under
consideration in this paper, it is required that the functions should be
at least five and six times differentiable respectively so that the
method is applicable to find the solution. This restricts the
applicability of the method and also the cost in finding the solution
increases as it involves the computation of higher order derivatives.
The local convergence analysis derived in this paper uses Lipschitz and
ω-continuity conditions which involves only first derivative (present in
the method) to prove the convergence. Moreover, the present study also
provides details about the radii of domain of convergence and also
estimates on error bounds. Therefore, it is evident that the present
study enhances the applicability of the methods under consideration. The
obtained results have been verified with suitable numerical
illustrations.
3D structure - 2D plate - 1D rod interaction problem
Authors: Ljulj Matko , Tambaca Josip
Published: August 2022

In this paper we consider the equilibrium problem of interaction of
three elastic bodies of different elastic properties. The main body is
the unit cube. On top of it is a thin layer/quboid of thickness
$\eps$ of material whose stiffness is of order
$\frac{1}{\eps}$ that in the middle
contains another cuboid which is of width and thickness
$\eps$ that is made of material with elasticity
coefficients of order
$\frac{1}{\eps^q}$ for
$q>0$. We show that the family of solutions of linearized
elasticity problems, when $\eps$ tends to zero,
converges to a solution of a problem that is posed only on the unit cube
with possibly additional elastic terms on the boundary related to the
plate/rod energy of the thin elastic parts. It turns out that there are
five different regimes related to different values of $q$
($q\in \langle 0,
2\rangle, \{2\},
\langle 2,
4\rangle,\{4\},\langle
4, \infty\rangle$) with different limit
problems. We further formulate a model posed on the unit cube that has
the same asymptotics when $\eps$ tends to zero as the
full 3d problem posed on the union of the unit cube and thin cuboids.
This model then can be used as the approximating model in all regimes.

Authors: Küffer Thomas , Haeberlin Andreas , Knecht Sven , Baldinger Samuel , Madaffari Antonio , Seiler Jens , Mühl Aline , Tanner Hildegard , Roten Laurent , Reichlin Tobias
Published: August 2022

Introduction: Contact force-sensing catheters are widely used
for ablation of cardiac arrhythmias. They allow quantification of
catheter-to-tissue contact, which is an important determinant for lesion
formation and may reduce the risk of complications. The accuracy of
these sensors may vary across the measurement range, catheter-to-tissue
angle, and amongst manufacturers and we aim to compare the accuracy and
reproducibility of four different force sensing ablation catheters.
Methods: A measurement setup containing a heated saline water
bath with an integrated force measurement unit was constructed and
validated. Subsequently, we investigated four different catheter models,
each equipped with a unique measurement technology: Tacticath Quartz
(Abbott), AcQBlate Force (Biotronik/Acutus), Stablepoint (Boston
Scientific), and Smarttouch SF (Biosense Webster). For each model, the
accuracy of three different catheters was measured within the range of
0-60 grams and at contact angles of 0°, 30°, 45°, 60°, and 90°.
Results: In total, 6685 measurements were performed using 4x3
catheters (median of 568, IQR 511-606 measurements per catheter). Over
the entire measurement-range, the force measured by the catheters
deviated from the real force by the following absolute mean values:
Tacticath 1.29g ±0.99g, AcQBlate Force 2.87g ±2.37g, Stablepoint 1.38g
±1.29g, and Smarttouch 2.26g ±2.70g. For some models, significant under-
and overestimation of >10g were observed at higher forces.
Mean absolute errors of all models across the range of 10-40g were
<3g. Conclusion: Contact measured by force-sensing
catheters is accurate with 1-3g deviation within the range of 10g to
40g. Significant errors can occur at higher forces with potential
clinical consequences.
CMMSE: A low-dimensional realization algorithm for periodic input/output behavioral systems
Authors: Aleixo José , Rocha Paula
Published: August 2022

The state-space realization of linear systems is of utmost importance in
linear systems theory. After the realization problem for the
time-invariant case has been solved, particular attention was paid to
the case of linear periodic systems (see, e.g. 1,2,3,4,5,6,7,8).
Recently, such systems have regained importance, for instance, in the
context of coding theory (see9), where periodic convolutional encoders
play an important role, 10. The majority of the contributions within
this area concern the realization of transfer functions as well as
impulse responses, thus excluding the case of input/output linear
systems without coprime representations. By the end of the eighties of
the last century, Jan C. Willems (see11,12) suggested an approach
(nowadays known as the behavioral approach) that considers a wider class
of systems and allows to overcome this drawback. According to this
approach, the central object in a system is its behavior which consists
of all the signals that satisfy the system laws (also called system
trajectories). Consequently, the behavior of a system with an
input/output representation that is not coprime, contains more
trajectories than the set of input/output signals defined by the system
transfer function. Our work takes this fact into account. Based on
results already obtained in 13,14, we revisit the problem of the
realization of linear periodic MIMO behaviors and give further insight
into this problem, which allows setting up an algorithm to compute a
low-dimensional state-space realization of a periodic behavior. The
proposed algorithm is based on a chain decomposition of suitable
matrices.

Published: August 2022

Background and Purpose: In recent decades, a focus on the most critical
and fundamental concepts has proven highly advantageous to students and
educators in many science disciplines. Pharmacology, unlike
microbiology, biochemistry or physiology, lacks a consensus list of such
core concepts. Experimental approach: We sought to develop a
research-based, globally relevant list of core concepts that all
students completing a foundational pharmacology course should master.
This two-part project consisted of exploratory and refinement phases.
The exploratory phase involved empirical data mining of the introductory
sections of five key textbooks, in parallel with an online survey of
over 200 pharmacology educators from 17 countries across six continents.
The refinement phase involved three Delphi rounds involving 24 experts
from 15 countries across six continents. Key Results: The exploratory
phase resulted in a consolidated list of 74 candidate core concepts. In
the refinement phase, the expert group produced a consensus list of 25
core concepts of pharmacology. Conclusion and Implications: This list
will allow pharmacology educators everywhere to focus their efforts on
the conceptual knowledge perceived to matter most by experts within the
discipline. Next steps for this project include defining and unpacking
each core concept and developing resources to help pharmacology
educators globally teach and assess these concepts within their
educational contexts.
The glycogen cargo receptor STBD1: from biology to disease targeted therapies
Authors: Tang Qiannan , Liu Meiqing , Zhao Hong , Chen Linxi
Published: August 2022

Glycophagy is a novel selective autophagy characterized by glycogen
degradation via the lysosomal enzyme acid α-glucosidase (GAA).
Starch-binding domain-containing protein 1 (STBD1) is a glycogen cargo
receptor that mediates glycophagy through binding glycogen transport
into lysosomes. STBD1-dependent glycophagy has garnered considerable
interest in the pathology community, because its dysregulation causes
multiple diseases, with cancer being the most serious. Notably,
deletions and/or mutations in STBD1 promote tumorigenesis. In this
review, we first summarized the current understanding of STBD1,
including its structure, subcellular localization, tissue distribution,
and biological functions. Next, we examined the roles and molecular
mechanisms of STBD1-dependent glycophagy in various diseases (e.g.,
Pompe disease, Parkinson’s disease, cardiac diseases, and cancer). Based
on available research, we discussed the promising function and future of
STBD1, including its potential application as a therapeutic target in
glycogen-related diseases. We recommend using real-time diagnostic tools
to observe the progression of STBD1-mediated glycophagy and gain further
insight on the mechanism of action. Such details are needed to
investigate new avenues for glycogen-related disease therapy.

Authors: Palande Dattatray , Ghuge Nilesh , Shrivastwa Rakesh
Published: August 2022

The globe has been compelled to develop other fuels due to tight emission restrictions, poor environmental circumstances, depletion of oil reserves, and rising prices of petroleum fuels. The rapid and rapid development of the automobile sector has resulted in a sharp increase in demand for petroleum-based fuels. Petroleum-based fuels have a finite amount of reserves. Biodiesel, a viable alternative fuel and has qualities that are similar to diesel fuels. By combining it with diesel, it can be a suitable fuel in diesel engines. Biodiesel, which is usually made from non-edible oils like Jatropha karanja oils, has sparked a lot of interest as a diesel engine alternative fuel. When compared to edible oil, non-edible oil is more helpful.Non-edible plants that may be grown in a variety of soils, including degraded woods, road edges, and irrigation canals. The goal of this study is to take review of the performance, combustion, and emission characteristics of Jatropha and Karanja biodiesel fuels in diesel engines in more depth. Researchers will benefit from this comprehensive analysis of the published literature in understanding the suitability of biodiesel as a diesel engine fuel substitute.

Involves the design policy from the possibilities that opens technology around peri - urban mobility, comfort of transport and satisfaction of the user which could combine with subsidies units zero emissions of carbon dioxide to the atmosphere, or alternative transport subsidies that use eco-routes, cycle tracks or pedestrian routes as well as electrified public transport.
Adult ADHD: A Brief Review
Authors: P Gentile Julie
Published: August 2022

In the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD), the psychiatrist may consider both stimulants and non-stimulant medications; in addition, there are some over the counter substances and adjunct medications that may be helpful in mitigation or resolution of symptoms. Behavioral, environmental and psychosocial approaches should be instituted in association with pharmacology and extra caution and conservatism should be used in patients under the age of 18 years and those diagnosed with Substance Use Disorders or Bipolar Disorder. When making clinical decisions, it is important to consider use of both immediate release and sustained release stimulant preparations, in addition to consideration of first line, second line and adjunct agents. It has been long recognized that the prominent central nervous system neurochemicals intimately involved with ADHD symptoms affect dopamine and/or norepinephrine receptor systems. Many consider ADHD to be largely a childhood condition, although there is evidence for two-thirds of patients to continue to experience symptoms into adulthood.

Psychotropics for Treatment of Substance Use Disorders in Adolescents: A Brief Review
Authors: P Gentile Julie
Published: August 2022

Substance use disorders (SUD) remain a long-standing problem for adolescents. Medication assisted treatment (MAT) is now standard treatment for adult SUD but less common in adolescents. This article provides a brief summary of the available psychotropics used to treat SUD in adolescent patients; psychotropics should be considered as one part of a multi-disciplinary approach to treatment of SUD. Due to the growing impact of the opioid public health crisis in the adolescent population, pediatricians have an expanding role in identifying and treatment of opioid use disorders, in addition to other substance use disorders. Pediatricians and adolescent medicine physicians are critically important in the solution to the addiction problem. There is expanding evidence that treatment of SUDs must be integrated into multiple parts of the delivery care system, including primary care settings. Medications Used to Treat Opioid Use Disorders (OUD): Methadone and buprenorphine are the two primary methods of MAT available to treat OUD. Methadone is highly regulated and only available to patients over age 18 in the United States. Buprenorphine/naloxone is FDA-approved for patients age ≥16, with the American Academy of Pediatrics Committee on Substance Use and Prevention (2016) recommending improved pediatrician access to buprenorphine training and MAT consideration for adolescents. Buprenorphine/Naloxone (Suboxone) and Buprenorphine (Subutex): Buprenorphine is a schedule III drug, requiring additional prescriber trainings and requirements. Buprenorphine is a mu-opioid partial agonist with greater safety margins than full agonists and less withdrawal. It is often combined 4:1 with naloxone, an antagonist; Alho, et al. found that this combination reduced “street value”, likely decreasing abuse potential.
A Comprehensive Survey on Role of Learning Approaches in Respiratory Disease Management with Special Focus on Asthma
Authors: MR Pooja
Published: August 2022

Asthma is a heterogeneous disorder with many phenotypes. We discuss the phenotypic characterization of asthma by which disease causality and ultimately management approaches can be developed to improve asthma control while avoiding adverse effects and decreasing the risk of serious outcomes. Thus the discussions would aim at phenotyping asthma based on clinical as well as physiological characteristics as Asthma is defined and diagnosed by a combination of clinical symptoms and physiologic abnormalities by deploying different learning techniques for devising novel approaches, while performing evaluation of the same, which would better define asthma phenotypes that may improve the understanding of the underlying pathobiology of the phenotypes and lead to targeted therapies for individual phenotypes. The approaches developed would serve to cluster, classify and further perform analysis and predict the severity of the disease in future effectively.
Orthoptists Services: A Review of Benefits Paid By Medical Schemes, South Africa
Authors: Mncedisi Willie Michael
Published: August 2022

Background: Orthoptists are specialists in diagnosing and treating ocular movement disorders and problems related to how the eyes work together, known as binocular vision. There is currently about 1 100 orthoptist registered and working in the UK. The comparative figure to South Africa is much lower at only nine registered orthoptists. Study design and objectives: This was a cross-sectional research study of claims paid for Orthoptists services by medical schemes. The study's primary objectives were to assess benefits paid for Orthoptists services, the level of co-payment subjected to members of medical schemes, and the funding model employed by medical schemes. The study entailed secondary data collected from the Council for Medical Schemes Annual Statutory returns. Results: The total number of beneficiaries with at least one orthoptist visit was 204, and the total number of visits paid by schemes was 256. This translates to the average number of one visit per beneficiary per annum. Each visit amounted to an average expenditure of R540. These services attracted a co-payment to the rand amount of R148 per visit. Nearly half of these benefits were paid from the person's medical savings account, accounting for 48% of benefits. Conclusion and recommendations: Coupled with evidence that there are currently no training schools for orthoptists and a low revenue base, this study shows that the demand for the services is lower than in previous years. The study recommends a review of the current model to a more multidisciplinary team across all specialties, particularly seeing that the first world countries still utilise the services of orthoptists in various health sectors, including child development and mainstream schools.

Authors: Mawunu Monizi
Published: August 2022

This study is the first ethnobotanical survey investigating the biodiversity of medicinal plants in the small Songo city (Northern Angola), as well as the indigenous knowledge related to the use of plant resources in healthcare by the local population. The study aims to document and help preserve and pass on this invaluable heritage to future generations. A field study was conducted between March 2020 and September 2021. A total of 522 informants were interviewed using the semi-structured method and random sampling technique. Demographic characteristics of the participants, local names of plants, parts used, and plant preparation methods were investigated and recorded. The database was analyzed using Relative Citation Frequency. The majority (71%) of the medicinal plants in Songo are of exotic origin compared to 29% of the native plants. Of the 62 species identified and considered medicinal according to popular use in the small Songo city, 53 spp. (85.5%) are dicots and 9 spp (14.5%) are monocots. The study recorded 62 plant species belonging to 57 genera and 30 families used as medicines for the treatment of various human diseases in Songo city. The most common families were Fabaceae (7 spp., 11.5%), Solanaceae (6 spp., 9.8%), Asteraceae (4 spp., 6.6%), Malvaceae (4 spp., 6.6%), Poaceae (4 spp., 6.6%), Anacardiaceae (3 spp., 4.9%), and Euphorbiaceae (3 spp., 4.9%). The main morphological forms are shrubs (36.0%), tree (26.1%), and herbs (23.6%). Leaves are the most commonly used organ (69.9%). Decoction (44.4%) and oral intake (60.4%) are the most common modes of remedy preparation and administration (47%), respectively. The main human diseases recorded are cough (10.3%), anaemia (7.9%), malaria (6.9%), diarrhea (6.1%), and yellow fever (5.7%). This high number of medicinal plant species documented shows that herbal remedies are highly utilized to treat various diseases among the local community living in the small city of Songo. Therefore, efforts are needed to improve the level of conservation of these species, and also to preserve traditional knowledge of remedies. We conclude that pharmacological and biological studies are necessary to scientifically support the medical potential of these species in the laboratory since they are constantly used in small city of Songo.

Health Care System Decentralization, the Case of Venezuela Historic Evolution, Results, and Consequences of its Institutional Reversal
Authors: Oletta Lopez Jose Felix
Published: August 2022

The author exposes the political, social, and technical foundations that motivate and justify the decentralization of health care services, as a means, not as an end. He highlights the Venezuelan constitutional and legal framework that establishes the foundations of transference and sets competencies. Throughout the article, the author highlights the fundamental role of the decentralization of modern Health Systems, for the equitable and efficient achievement and quality health services and products, with the participation of the communities, as well as the conditions and requirements for its application; the purposes, objectives, benefits, and new challenges derived from its implementation. A historical recount is made on the experience garnered by the decentralization of the health care sector in Venezuela. The process for the construction of the Decentralization and Transfer of Competencies Agreements is briefly described, as well as the scope, limitations, and implementation results in the Venezuelan health care system. Briefly I explain the process of nonapplication of the Constitutional norm, and later reversal of the decentralization in health care which occurred from 2007, and its consequences. Finally, I pose strategic proposals for the defense of decentralization.
Image-based disease detection and classification in Indian apple plant species by using deep learning
Authors: Wani Sidrah Fayaz , Ashraf Arselan , Sophian Ali
Published: August 2022

Plant diseases are a major threat to food security, but their rapid identification remains difficult in many parts of the world due to the lack of the necessary infrastructure. Traditional farming methods are insufficient to address the impending global food crises. As a result, agricultural productivity growth is critical, and new techniques and methods are required for efficient and sustainable farming practices that balance the supply chain according to customer demand. Even though India is one of the most agriculturally dependent countries, it nevertheless suffers from various agricultural shortages. Plant diseases that go unnoticed and untreated are one such deprivation. Developing an intelligent automated technique for plant disease detection is explored in this research. Deep learning is used to create a smart system for image-based disease detection in Indian apple plant species. Specifically, this study uses a convolution neural network architecture, ResNet-34, to identify diseases in apple plants. Based on 70-30% and 80-20% dataset partition, the proposed model obtained an accuracy of 97.5% and 98.4%, respectively. The results obtained from this study illustrate the productive exploration and utility of the proposed model for future research by implementing various deep learning models and incorporating additional modules that provide cure and preventative measures for the detected diseases.
Redesign of water-diesel emulsion fuel mixer
Authors: Mahadi Abram Anggit , Santoso Budi , Ubaidillah Ubaidillah , Lenggana Bhre Wangsa
Published: August 2022

Emissions and fuel consumption are essential parameters to indicate the working of a combustion engine. This paper discusses the methods to achieve lower emissions and efficient fuel consumption. One of the methods is by making emulsion fuel. The emulsion-making methods are surfactant emulsion, micro-emulsion, ultrasonic emulsion, and real-time emulsion non-surfactant (RTES). In the research, the emulsion fuel is a mixture of B30 Biodiesel and water without surfactant that is supplied in real-time after being mixed in a mixer. The ratio is 85% biodiesel and 15% water. The RTES mixer in the old model has a big size, and high-power consumption of about 150-433,5 W. This research's purpose is to develop a simple design and low power consumption of the RTES Mixer. The new RTES mixer design only needs 150 W motor power. Its dimension is more superficial and produces tiny droplets with a main diameter range between 0.1 to 0.5 ?m, with good-mixed visually.
Investigation of electrical tree stress using colour techniques
Authors: Abderrazzaq Mohammad
Published: August 2022

Treeing is one of the severe problems which cause the deterioration and breakdown of electrical insulation materials. Different approaches have been used to characterise this phenomenon, from experiments to analysis. The results of both methods were criticised for their dependence on the assumptions and applied conditions. In this work, the role of colours in understanding the characteristics of electrical treeing in composite insulation was employed. The relationship between the induced strain, associated with the electrical tree, and the change of colour parameters, represented by hue, saturation, and value indicators, was presented. The images were created by relative retardation orthogonal components of the polarised white light used to illuminate the specimens in the microscope. An image-editing software was used to analyse the tree colours, whereas the MATLAB program was written to determine the colour mapping of examined image. The variation of each colour parameter was linked with the tree distribution. It was then introduced as an indicator of stress at each examined point. Therefore, the contribution of the present paper is summarised as an introduction of a new tool to characterise stress in insulation materials by converting a treed image into a numerical array of data without the need to follow a complex mathematical procedure. Finally, this paper can better assess the treeing phenomenon by correlating the direction of tree growth to the rate of change for each colour parameter in that direction.

Date palm (Phoenix dactylifera) is a plant of the Phoenix palms whose fruit tastes sweet and can be consumed by humans. These fruit seeds usually only become a waste and never be utilised by people. The research tries to reduce the waste of date palm by using the date palm fruit seeds to replace the coffee beans. One of the processes of changing date palm fruit seeds to coffee beans is drying the seeds. Instead of using a traditional drying method, this study has designed a prototype of an Internet of Things (IoT) based monitoring system tools inside the drying room that allow humidity and temperature sensors, heater, fan, and mixer to be monitored through a smartphone in real-time. Hence, the monitoring tools inside the drying room could be controlled easily, and the data could be saved as databases in smartphone applications.

D2 high chromium tool steel is widely used to produce tools and components that work at significant dynamic loads, such as dies, punches and rollers. The steel must have a good combination of strength and toughness, which heat treatment can obtain. Therefore, this study discusses the effect of normalising, hardening, and tempering on the microstructure and hardness of D2 tools. Normalising and hardening were carried out respectively at 1020°C for 30 minutes, followed by rapid cooling using oil. Tempering was realised by reheating the quenched sample at 250°C and 400°C with variations in holding time of 15 minutes, 30 minutes, and 45 minutes. The hardness of the specimens was measured using a Rockwell hardness tester, whereas the microstructure was observed with an optical microscope. The results indicated that the microstructure changes to martensite and carbide after quenching, while the microstructure becomes tempered martensite and carbide after tempering. Normalising and hardening have almost no impact on hardness, and the increase in temperature and holding time causes a decrease in hardness. The reduction in hardness is noticeable for steels tempered to 400 °C and held for 45 minutes.
Human resources and workforce shortages in Jeju Island due to islandness: The challenges faced by former hospitality and tourism professionals
Authors: Dos Santos Luis Miguel
Published: August 2022

Workforce management is a problem in many islands. Although the Jeju tourism department and local business offer attractive promotions and opportunities, due to the demands faced by tourism professionals, many have left their positions in Jeju and returned to the mainland Korean peninsula. The purpose of this study is to explore the motivations, career decisions, and turnover behaviours of a group of former tourism professionals who had previously worked in Jeju for a period of less than two years. Based on social cognitive career and motivation theory, the study was guided by two research questions: 1) Why did the participants leave their positions in Jeju after less than two years of career development? and 2) How did the participants describe their working and living experiences in Jeju as professional tourism workers? The data from 42 participants indicated that overloaded responsibilities and unbalanced schedule, financial consideration, and personal consideration were the three major reasons for leaving Jeju. This study aims to help local businesses and governments to understand employees’ motivations, career decisions, and turnover behaviours. Further, this research seeks fill gaps in the literature regarding workforce shortages and tourism management for islands and remote regions, particularly in East Asia.

The globalization of island studies has resulted in a greater recognition by island studies scholars of the need for more regional-based island research to encompass the diversity of island knowledge and experiences. Island research in East Asia provides examples of both English and native language perspectives across four distinct socio-cultural contexts: Japan, South Korea, the Chinese mainland, and Taiwan. Historical literature and contemporary scholarly research provide a context for understanding: (1) how East Asian researchers engaged with island studies and islandness; and (2) how East Asian socio-economic development policies reflect understandings of islandness locally and across the region. We found similarities among the four East Asian regions, but also variations based on different domestic political perspectives. Given the late start of island research in East Asia, many topics await more detailed future examination.

The use of Information Technology for the information center on the COVID-19 web in Batam city and the COVID-19 web in Indonesia, must be supported by IT Governance which describes the most important factors in the use of IT. In addition, the development of the internet also supports the use of computers. The data on the two websites may still not be used as the main reference data due to differences in data from the national web version and Batam City, also because the data obtained are not aligned and do not intersect, it can cause errors in reporting the data that has been collected in such a way. In this study, an Information System Audit will be carried out with the process of collecting and also evaluating evidence about the accuracy of the available information to determine the level of suitability of the information with the audit standards that have been set and express the results of the examination, based on the information system audit standards. The results of the assessment of aspects of the security system, design, navigation, mobile friendly, speed, content quality and keywords of the two websites show that it is very worthy to say that it is very good.

Keamanan merupakan salah satu aspek yang paling penting dalam jalannya proses pertukaran informasi di masa ini. tidak semua informasi yang dipertukarkan dapat diperbolehkan menjadi konsumsi publik apalagi jika jatuh ke tangan pihak yang tidak bertanggung jawab yang dapat mengubah, memanipulasi dan menyebarkan informasi tersebut tanpa izin. Salah satu bentuk informasi yang perlu dilakukan langkah pengamanan ialah data video streaming. Metode enkripsi adalah pilihan yang paling tepat untuk mengamankan kerahasiaan data tersebut. Enkripsi merupakan sebuah ilmu untuk mengkonversikan sebuah data menjadi bentuk yang tidak dapat dimengerti guna menyembunyikan informasi yang hanya dapat diakses oleh pihak yang berhak. Penelitian ini memanfaatkan algoritma enkripsi AES-Rijndael untuk mengamankan data dan informasi dari video streaming yang dilakukan antara client dan server dengan memanfaatkan protokol transmisi RTP dan RTSP dalam kontrol alur media, enkripsi AES-Rijndael akan digunakan untuk mengubah data dari format file video berekstensi Mjpeg. Algoritma AES-Rijndael mampu mengamankan data dan informasi video dengan baik, ketika client memasukan kunci dekripsi yang berbeda, frame video yang dikirimkan dari server tidak dapat didekripsi dan ditampilkan secara utuh. Pengujian hashing SHA-256 dilakukan pada 25 dan 50 frame dari video untuk mengecek keaslian data berjalan dengan baik tanpa ada perubahan pada data frame yang dikirimkan.
