Authors: Druva Patha
Published: June 2023

Abstract: India has established itself as a prominent player in the global agriculture sector and has predominantly relied on an agriculture-based economy. However, a significant number of farmers and individuals involved in agriculture face various challenges due to limited knowledge of agricultural production. These challenges include inadequate farming techniques, insufficient crop materials, improper crop planning, and imbalanced fertilizer usage. This project presents a prototype of a chatbot framework designed to assist individuals, including farmers, in managing their crops and predicting their needs. The chatbot predicts fertilizer requirements, nutrient levels in crops, and provides valuable knowledge to users regarding basic agricultural needs. The structure employs Natural Language Processing and draws information from pre-determined data to deliver responses to user queries. To ensure accuracy, the chatbot analyzes previous interactions and sources data from "The Indian Council of Agricultural Research."
Spam SMS Prediction Using Machine Learning
Authors: Choudhary Esha
Published: June 2023

Abstract: As the popularity of mobile phone devices has increased, Short Message Service (SMS) has grown into a multi-billion dollars industry. At the same time, reduction in the cost of messaging services has resulted in growth in unsolicited commercial advertisements (spams) being sent to mobile phones. In parts of Asia, up to 30% of text messages were spam in 2012. Lack of real databases for SMS spams, short length of messages and limited features, and their informal language are the factors that may cause the established email filtering algorithms to underperform in their classification. In this project, a dataset of real SMS Spams from UCI Machine Learning repository is used, and after pre-processing and vectorization, different machine learning algorithms are applied to the dataset. Finally, the results are compared and the best algorithm for spam filtering for text messaging is introduced and converted into an open-source website. The SMS spam collection set is used for testing the method. After collecting the various supervised learning algorithms, we find that the Multinomial Naïve Bayes algorithm gives us 97.1% Accuracy and 100% Precision

Published: June 2023

Abstract: Web 2.0 and now Web 3.0 has created great heights in the face of the Internet industry. The distance from Web 1.0 to Web 2.0 has been covered for almost a decade. But soon after Web 2.0 a new Web 3.0 evolved which has not only raised the level of interest but also many questions among developers, users, and regulators. Do we need it at this stage, what are the forcing factors, how it is different from Web 2.0 and the Semantic Web, what are its social, moral, and security implications, is it only about personalization, all these questions have made Web 3.0 popular among its stakeholders. In this paper, the primary focus will be on the relationship between Web 2.0, Web 3.0, and the Semantic Web while the second will be on the rising security concerns about rapid and sequential Web developments. However, the changing business models in the future of Web 3.0 will also be highlighted

Published: June 2023

Tanaman karet di Sumatra, Jawa, dan Kalimantan pada beberapa tahun terakhir mengalami gugur daun berkepanjangan. Kesulitan mencari benih untuk batang bawah memunculkan pertanyaan apakah benih dari tanaman muda layak digunakan untuk batang bawah dimana pada kondisi normal tidak dianjurkan. Penelitian ini membandingkan karakteristik fisik, tingkat kesegaran benih, dan daya kecambah dari tanaman muda berumur sembilan tahun dan tanaman dewasa berumur 17 tahun dari klon PB 260 yang mengalami gugur daun berkepanjangan. Penelitian dilaksanakan di rumah kaca Unit Riset Sungei Putih, Pusat Penelitian Karet, Deli Serdang, Sumatra Utara pada bulan Februari sampai Maret 2023. Parameter fisik yang diamati meliputi panjang, lebar, rasio panjang/lebar, dan bobot benih. Uji kesegaran menggunakan 25 sampel benih. Daya kecambah diamati sampai dengan tiga minggu setelah semai. Hasil pengamatan menunjukkan perbedaan nyata antara benih tanaman muda dan dewasa untuk parameter panjang (24,07 + 2,31 mm berbanding 25,58 + 1,74 mm), lebar (22,16 + 2,32 mm berbanding 23,05 + 1,82 mm), dan bobot benih (3,83 + 0,58 g berbanding 4,16 + 0,59 g), sedangkan rasio panjang/lebar tidak berbeda antara kedua umur tanaman (masing-masing 1,09 + 0,06 dan 1,09 + 0,07). Kesegaran benih tidak berbeda nyata antara tanaman muda (33,3 + 7,54%) dan dewasa (41,3 + 4,99%). Perlakuan perendaman satu malam tidak meningkatkan kesegaran benih secara nyata. Daya kecambah tidak berbeda nyata antara benih dari tanaman muda (7,23 + 2,96%) dan tanaman dewasa (21,96 + 13,51%). Penelitian ini menunjukkan bahwa pada tanaman yang mengalami gugur daun berkepanjangan, bentuk benih relatif sama namun ukuran benih tanaman muda lebih kecil. Nilai kesegaran benih dan daya kecambah tidak berbeda nyata antara tanaman muda dan dewasa, keduanya menunjukkan nilai di bawah standar benih normal. Namun demikian, rata-rata daya kecambah benih dari tanaman muda tidak sampai setengah dari nilai daya kecambah benih tanaman dewasa, sehingga penelitian ini mendukung rekomendasi bahwa benih tanaman muda (< 10 tahun) tidak dianjurkan digunakan untuk batang bawah.
A Comparative Study on Sense Utilization of Cathedral and Escorted by Light: Focused on the New Function of Expressionism
Authors:   Institute of Foreign Literature, Tak Hee Yeon
Published: June 2023

This thesis analyzes how ‘expressionism’ is used in contemporary literature through reading Cathedral by Raymond Carver and Escorted by Lighted by hae-jin Cho. ‘Expressionism’ is an art period that appeared in the 20th century and has the aim to express a subjective psychological condition of a character. This thesis limits ‘expressionism’ to the ‘senses’ of humans. The first person and the main character of each two short-story portrays vividly the inner world of themselves through the ‘five senses’, especially the ‘sense of touch’ and the ‘sense of sight’. Furthermore, the utilization of ‘sense of touch’ and ‘sense of sight’ have the feature of the medium of the narrator to understand other people. Eventually, the ‘expressionism’ in contemporary literary works has the hopeful function of suggesting ‘the possibility of solidarity’ and beyond ‘the connection to the community’.

Published: June 2023

Over the last decade, learning and working in medicine have been increasingly influenced by digital tools and the “digital transformation” is now a popular topic. Today’s medical students are growing up in a digital age in which digital tools and devices are a regular part of their professional life. Digital transformation in healthcare is not just about technology but strategy and new ways of thinking. Developing digital competence is essential to health professional education to increase confidence in accessing the best evidence for clinical practice. Healthcare lecturers play a crucial role in promoting the acquisition of digital competencies and therefore need to be digitally competent themselves. This study aims to identify teachers’ digital competence at one medical college using the framework for the Digital Competence of Educators (DigCompEdu). A total of 47 medical college teacher participated. The results confirmed that the self-assessment instrument developed is reliable, valid, and thus suitable for measuring teachers’ digital competence. Generally, values are centred across the four major competence categories, and most participants obtain a score at the intermediate (B1) level. Investing in teacher training aimed at practical work with students is necessary, as the area showing the most significant weaknesses is Area 5: Empowering Learners. In particular, teachers also need to help their students use technologies in their education.

Published: June 2023

Artificial intelligence (AI) has become a popular technology of this era due to its potential to transform businesses. Therefore, various businesses are focused on adopting this technology to enhance their business. However, due to challenges, not all organizations can adopt AI for their business functions. Considering the importance of AI and small and medium-sized enterprises (SMEs) in the economy, this study aimed to examine the challenges and prospects of AI for SMEs. The study performed review-based research to examine past literature to determine the key challenges facing SMEs in AI integration. It was noted in the results that costs and technical requirements of AI remain the topmost challenges for SMEs to implement AI. These challenges remain the major hindrance to the adoption of AI, and thus, this study analyzes these issues deeply to provide organizations with the insight to overcome these problems. The study also noted that the prospects of AI in SMEs are great as the costs of AI are reducing, and with more research and development, AI integration will become more convenient. Therefore, this research provides key details into the problems facing AI adoption contemporarily and how they can be solved in the future.

Correlation between landscape pattern and net primary productivity in arid and semi-arid areas of Northwest China
Authors: Xu Congrui , Xiong Xueting , Li Hong , Ma Yuxin , Zhang Yuna
Published: June 2023

Human activities and environmental changes have affected the changes of
landscape pattern, and then profoundly affected the changes of net
primary productivity (NPP) of vegetation. Understanding the relationship
between landscape pattern and NPP is of great significance for
maintaining the stability of ecosystem and improving ecological
environment. Based on six types of land use in arid and semi-arid areas
of northwest China, this study selected five landscape pattern indexes
at the landscape level and four landscape pattern indexes at the class
level, and analyzed the relationship between landscape indexes and NPP
at the grid scale of 100km×100km by Pearson correlation and multiple
linear regression model. The results showed that the landscape pattern
index and NPP showed different degrees of correlation from 2001 to 2020,
and changed in different degrees in the past 20 years. The correlation
between indicators and NPP is higher at class level than at landscape
level, and the increase of landscape abundance and fragmentation
promotes the increase of NPP. At the landscape level, NP, PR and SHDI
explained 45.4% of NPP changes. At the class level, NP, TE and IJI were
the main influencing factors of NPP in cultivated land, woodland and
grassland. The correlation between landscape index and NPP and multiple
linear regression model can help us to quantitatively understand how the
change of landscape pattern affects the change of NPP, and we should
properly consider the change of landscape pattern in ecological
management, so as to maintain the stability of the ecosystem.

A 72-year-old lady without any conventional cardiovascular risk factors
presented to the emergency room with severe anginal chest pain. ECG
showed lateral wall ST-elevation and serial serum troponins were
elevated. Emergent cardiac catheterization showed spontaneous coronary
artery dissection involving the first diagonal artery with
angiographically normal other epicardial coronary arteries. Left
ventriculogram and echocardiogram showed a moderately reduced left
ventricular systolic function with akinetic mid to distal myocardial
segments and normal basal contraction suggestive of stress-induced
cardiomyopathy. Spontaneous coronary artery dissection presenting with
ST-elevation myocardial infarction and stress-induced cardiomyopathy is
very rare.
Eating Behaviors Associated with Suicidal Behaviors and Overall Risk
Authors: McCord David , Sutphin Terran , Hicks Adam
Published: June 2023

Maladaptive eating behaviors remain prevalent in the U.S. population,
and a significant percentage of U.S. college students acknowledge
engaging in maladaptive eating. Formally defined eating disorders (EDs)
have the highest mortality rate of any other mental illness. Suicide
risk is substantially elevated among individuals diagnosed with EDs, and
even subclinical levels of maladaptive eating behaviors are associated
with suicidality. The current study examined associations between
specific problematic eating behaviors measured dimensionally (e.g.,
purging, binging, laxative use) and specific suicide-related constructs
and behaviors as well as overall suicide risk. College students (n=188;
62% women) completed the EDE-Q, a well-established measure of
dysfunctional eating, as well as several self-report measures of
theoretical components of suicidality, and, finally, a semi-structured
clinical interview. Results showed a general pattern of moderate and
strong associations between the subscales and overall score of the EDE-Q
and core suicide constructs of the interpersonal-psychological theory of
suicide (IPTS). Many substantive correlations were found between
specific eating behaviors and specific suicide-related behaviors; for
example, purging was the highest correlate of overall suicide risk (
ρ = .36). These results are discussed in terms of consistency
with the IPTS as well as practical implications for intervention.
Critical issues in family peer support in a youth mental health service
Authors: Whitson Sarah , Haan Zsofi de , Preece Susan , Swinson Maureen , Williams Sue , Smith Karen , Bité Jennifer , Zbukvic Isabel , Simmons Magenta
Published: June 2023

Background: Family peer workers form connections with family/carers and
can offer emotional support, psychoeducation and referrals based on
their own lived experience. Although an increasing number of family peer
support programs exist in the youth mental health sector, they are
rarely described or reported on. There is a need for greater
documentation of the experiences of family peer workers operating in the
healthcare sector, in order to raise awareness of issues currently
facing the workforce and support organisations to make positive changes.
Methods: We present a detailed description of the family peer support
program at Orygen in Victoria, Australia. In doing so, we highlight
factors that impact effective program implementation and delivery from
the perspectives of four family peer workers and two supervisors.
Findings/Conclusions: Organisations should encourage self-care and
social connections between family peer workers to reduce impacts of
ongoing mental-ill health and workplace burnout and isolation. Staff
should be educated about the field of family peer support to improve
role clarity and foster a positive team environment. It is vital to
develop a comprehensive position description, training program, and
onboarding procedures to ensure new employees are adequately equipped.
To improve staff retention and compensate those with further education,
experience and skills, organisations may consider offering increased
remuneration, negotiate longer-term contracts with a potential for a
greater number of workdays, and should promote/hire senior lived
experience positions. Further research is needed to formally investigate
barriers and facilitating factors of program implementation in mental
health settings.
Leveraging whole genome sequencing to estimate telomere length in plants
Authors: Paez Michelle Zavala , Holliday Jason , Hamilton Jill
Published: June 2023

Changes in telomere length are increasingly used to indicate species’
response to environmental stress across diverse taxa. Despite this broad
use, few studies have explored telomere length in plants. However, rapid
advances in sequencing approaches and bioinformatic tools now allow
estimation of telomere length using whole genome sequencing (WGS) data.
Thus, evaluation of new approaches for measuring telomere length in
plants are needed. Traditionally, telomere length has been quantified
using quantitative polymerase chain reaction (qPCR). While WGS has been
extensively used in humans, no study to date has compared the
effectiveness of WGS in estimating telomere length in plants relative to
traditional qPCR approaches. In this study, we use one hundred Populus
clones re-sequenced using short-read Illumina sequencing to quantify
telomere length using three different bioinformatic approaches,
Computel, K-seek, and TRIP, in addition to qPCR. Overall, telomere
length estimates varied across different bioinformatic approaches, but
were highly correlated across methods for individual genotypes. A
positive correlation was observed between WGS estimates and qPCR,
however, Computel estimates exhibited the greatest correlation. Computel
incorporates genome coverage into telomere length calculations,
suggesting that genome coverage is likely important to telomere length
quantification when using WGS data. Overall, telomere estimates from WGS
provided greater precision and accuracy of telomere length estimates
relative to qPCR. The findings suggest WGS is a promising approach for
assessing telomere length, and as the field of telomere ecology evolves
may provide added value to assaying response to biotic and abiotic
environments for plants needed to accelerate plant breeding and
conservation management.

Published: June 2023

Healthcare worldwide has undergone a tremendous evolution in recent
decades. Due to the evolution of medicine and the explosion of various
ingenious and more expensive examination and treatment options. This
ensures that patients are treated more and more efficiently, and
admission times are drastically reduced. Not only medicine is creating
new challenges, but social developments are also setting the scene for a
renewed healthcare organisation. The healthcare sector and governments
face enormous challenges. The changing landscape is shifting the focus
from episodic acute care to chronic continuous care. Consider the
participation needs of patients, the documentation and accountability of
quality of care, the ageing of the population, evolution towards
supra-regional hospital networks in Belgium and the alignment with-and
substitution of-care to primary care. The nursing profession must evolve
along with it, but the amount of knowledge we expect from nurses both in
terms of knowledge of pathology but also broader knowledge of
informatics, technology makes it particularly complex. In response to
these challenges, AZ Groeninge Belgium has developed a new model of care
in recent years.
The Nationalization of Animation Art: Research on the Experimental Animation Creation of the She Nationality
Authors: Zhang Yuqin , Zhang Shouyong
Published: June 2023

By drawing nutrients from the traditional culture of the She ethnic
group, and by using the unique cultural elements of the She ethnic group
as explicit image carriers to convey the implicit folk customs and
beliefs of the She ethnic group, the animation works are endowed with
the cultural connotations of the She ethnic group, while at the same
time providing a carrier for the inheritance and development of the
traditional culture of the She ethnic group.The animation work “She
Herbs” takes the application of traditional She culture and animation
creation as the main theme, and studies how to reasonably apply
traditional She cultural elements in the script story, character design,
scene design, art style design and sound design in the creation of
animation art, so as to make it an animation design work with regional
cultural characteristics, so that the artistic expression and ideology
can be better integrated in the work. The attempt to combine the rich
and colourful traditional culture of the She people with animation has
brought a rich source of inspiration and creative nourishment to the
creation of the short animated art film “She Herbs”.
Kanały dystrybucji a sytuacja ekonomiczna gospodarstw sadowniczych
Authors: Rysz Maria , Szymańska Elżbieta
Published: June 2023

Celem opracowania było rozpoznanie kanałów dystrybucji, z których korzystają sadownicy oraz próba odpowiedzi na pytanie, czy wyniki ekonomiczno-finansowe zależą od liczby wykorzystywanych kanałów dystrybucji owoców. Analizą objęto 45 gospodarstw z regionów Małopolski i Pogórza, które prowadziły rachunkowość dla potrzeb FADN w 2019 roku i zebrano z nich dane za 2018 rok. Z badań wynika, że większość gospodarstw sprzedawała swoje produkty, korzystając z kilku kanałów dystrybucji, ale były także takie, które korzystały z jednego. W badanej grupie sadowników główną formą zbytu owoców była sprzedaż w punktach skupu. Wiązało się to z dużą ich liczbą w badanych regionach. Inne kanały zbytu owoców to sprzedaż przez pośredników, na rynku hurtowym, do zakładu przetwórczego oraz na lokalnym targowisku. Największe trudności ze zbytem owoców w badanych gospodarstwach wynikały z braku stałych odbiorców czy podpisanych umów kontraktacyjnych. Wyniki ekonomiczne gospodarstw sadowniczych w grupach o różnej liczbie stosowanych kanałów dystrybucji były zróżnicowane. Wyższe wyniki ekonomiczne osiągały gospodarstwa o zdywersyfikowanych formach sprzedaży owoców. Badania wykazały zależność statystycznie istotną między wielkością i wartością produkcji a liczbą wykorzystywanych kanałów dystrybucji.

Published: June 2023

OBJECTIVE

Tirzepatide reduces HbA1c and body weight, and creatinine-based estimated glomerular filtration rate (eGFR) decline. Unlike creatine-derived eGFR (eGFR-creatinine), cystatin C–derived eGFR (eGFR-cystatin C) is unaffected by muscle mass changes. We assessed effects of tirzepatide on eGFR-creatinine and eGFR-cystatin C.

RESEARCH DESIGN AND METHODS

Our primary outcome was eGFR change from baseline at 52 weeks with pooled tirzepatide (5, 10, and 15 mg) and titrated insulin glargine in adults with type 2 diabetes and high cardiovascular risk (SURPASS-4).

RESULTS

Least squares mean (SE) eGFR-creatinine (mL/min/1.73 m2) changes from baseline with tirzepatide and insulin glargine were −2.5 (0.38) and −3.9 (0.38) (between-group difference, 1.4 [95% CI 0.3–2.4]) and −3.5 (0.37) and −5.3 (0.37) (between-group difference, 1.8 [95% CI 0.8–2.8]) for eGFR-cystatin C. Baseline, 1-year, and 1-year change from baseline values significantly correlated between eGFR-cystatin C and eGFR-creatinine. Measures of eGFR changes did not correlate with body weight changes.

CONCLUSIONS

Tirzepatide slows the eGFR decline rate, supporting a kidney-protective effect.

A rectangular isotropic two-layer plate of an irregular structure is considered, the edges of which are freely supported, and a constant temperature is maintained on them. Two-dimensional Kirchhoff-type thermoelasticity equations and two-dimensional heat equations written for an inhomogeneous material were used to study the temperature stresses in the plate. Using the method of double trigonometric series in spatial variables and the Laplace integral transformation over time, the general solutions of boundary value problems of thermoelasticity and heat conductivity for this plate under the action of a locally distributed temperature field specified at the initial moment of time are written down. The normal stresses in the layers of the plate are numerically analyzed depending on the geometric parameters, heat transfer coefficient, and time.

The article focuses on the linear estimation problems of unknown rectangular matrices, which are solutions of linear matrix equations with the right-hand sides belonging to bounded sets. The random errors of the observation vector have zero mathematical expectation, and the correlation matrix is unknown and belongs to one of two bounded sets. Explicit expressions of the guaranteed root mean square errors of estimates for linear operators acting from the space of rectangular matrices into some vector space are given. Guaranteed quasi-minimax root mean square errors of linear estimates are obtained. As the test examples, two options for solving the problem are considered, taking into account small perturbations of known observation matrices.

The evolution scheme phase, in which the genetic algorithms select individuals that will form the new population, had an important impact on these algorithms. Many approaches exist in the literature. However, these approaches consider only the value of the fitness function to differenciate best solutions from the worst ones. This article introduces the parenting fitness, a novel parameter, that defines the capacity of an individual to produce fittest offsprings. Combining the standard fitness function and the parenting fitness helps the genetic algorithm to be more efficient, hence, producing best results.

A model of money income diffusion is constructed taking into account the processes of social comparison and the development of the income formation spatial structure. To implement such model, the analytical theory of continued fractions is used and the corresponding differential equation solution is found in the form of a formal functional continued fraction. The values of the approach fractions of a continuous fraction describing the dynamics of changes in the level of money income give an approximation of the real values with almost predetermined, arbitrarily high accuracy. This allowed us to qualitatively describe the general dynamics of the money income diffusion process.
Impact of traffic volume and composition on the change in the speed of traffic flow
Authors:   Lviv Polytechnic National University, Hrytsun Oleh
Published: June 2023

The problem of the change in the speed of traffic flow at different traffic volumes and compositions is researched in this study. The section of the road network with different geometric parameters (descent, ascent and horizontal section) was chosen for the study. The method of investigation of traffic flow`s speed and factors which have an impact on the reduction of road network capacity are analyzed. The change in the coefficients of the unevenness of traffic flow by hours of the day in the studied area was determined and a graph of the distribution of traffic volume by hours of the day was built. A diagram of the section was built to determine the speed of the traffic flow, on which the movement along the horizontal section, uphill and downhill movement is present. It was established that at a traffic volume of 700-800 p.c.u./h, the traffic flow moves at a constant speed (up to 10-15 km/h). Cumulative curves of traffic flow speed` distribution characterizing modes of traffic flow on the road network were built. It is determined that at volume-capacity ratio 0< z ≤ 0,4 on three investigated sections traffic flow moves with the speed from 35 km/h to 59 km/h. In the specialized software product PTV VISSIM, the simulation of the traffic flow on the horizontal section, ascent and descent has been developed. Using the MATHLAB software environment, it is shown how the speed of the traffic flow changes depending on the volume-capacity ratio and the share of the heterogeneous traffic flow. It was established that the highest speed of the flow is observed during the downhill movement – 58.62 km/h at the volume-capacity ratio – 0.13 and the share of heterogeneous traffic flow – 1.0 (100% cars). At a volume-capacity ratio of 0.88 and existing road conditions, the speed of traffic flow on the horizontal section and during uphill movement is almost the same (the average deviation is 6%). It can be explained by the fact that at a volume-capacity ratio of 0.88, traffic flow is in the traffic jam, hence, the speed of movement on the three sections is the same.

When predicting public transport routes in cities, important indicators should be considered: the duration of stay on the bus route, passenger flow on the bus route, points of attraction and the passenger’s average waiting time at stops. These indicators are the basis for planning the operation of city transport. In particular, predicting the duration of traffic by studying the average passenger’s waiting time at stops is an important planning tool for transport companies. Therefore, this study can improve the quality of scheduled services by reducing the gap between actual and scheduled travel time. This article discusses this relevance and, based on experimental evidence, points to the benefit of using studies of average passenger waiting times, especially considering population groups. In fact, most of the factors which affect public transport operation, as had been proven by previous studies, follow a definite mathematical methodology. The analysis was performed using the data from field studies of passenger flow at bus stops (Lviv, Ukraine). The study of passengers at stopping points makes it possible to improve the quality of public transport services (calculate travel duration between stops and the duration of stay at them more accurately). The duration of stay at selected objects depending on a number of passengers was studied. Also, there are given the results of a study of the waiting time of public transport passengers at bus stops are given. A comparison of the dependence of the bus waiting time on population groups was obtained. After receiving this information, system operators can design and adjust the data according to the estimated trip duration. Nevertheless, it is necessary to carry out research at different types of stops in different parts of cities to clarify these data and for a more detailed analysis.

The movement of motor vehicles at high speeds is impossible without a braking system capable of ensuring high braking efficiency. It has been established that the most unstable link of the braking system is the brake mechanism, since from the energy point of view, braking with friction brakes is the process of converting part of the mechanical energy of the motor vehicle into heat. Braking is a long process during which many counterbody parameters change, in particular, thermophysical parameters due to temperature changes, friction coefficient, etc. If, under these circumstances, the surface and volume temperatures exceed the permissible values, then the frictional properties of the friction pairs and the conditions of the interaction of the parts change, which leads to a change in the characteristics of the brake mechanisms and the brake system as a whole. The standards of most countries and international prescriptions regulate braking performance meters not only for one-time emergency braking with cold brakes but also for emergency braking performed after the conversion of a given amount of energy into heat during a given time. It was found that the preservation of the necessary braking efficiency after the conversion of a given amount of energy into heat will be ensured only if the braking system has sufficient energy capacity. The object of the research is the distribution of heat flows in the elements of the brake mechanism, which determine the critical temperature of the friction surfaces. It was established that F. Charron's formula cannot correctly estimate such a distribution due to taking into account only the thermophysical properties of materials of friction pairs. It is shown that the influence of the design parameters of the brake and its modes of operation on the distribution of heat flows in the drum brake of a motor vehicle can also be estimated on grid thermal models with the involvement of the "Fourier-2xyz" software complex.

The incidence of inconclusive elections in Nigeria has attracted diverse perspectives in recent times. The significance of this discourse to the consolidation of Nigeria’s democracy cannot be ignored considering its consequential effects on the country’s electoral process. In what seems to be an unusual jurisprudential and political development was the case of John Faleke v Independent National Electoral Commission (INEC) & Anor which posed a peculiar scenario that was unprecedented to the evolution of electoral disputes in Nigeria. In line with the Constitution of the Federal Republic of Nigeria (CFRN), the Independent National Electoral Commission is empowered to organize or undertake and to supervise all elections to key offices including those of the President and Vice President, Governor, and Deputy Governor among others. It is in the exercise of this power that the INEC developed the Electoral Act and Election Manual used for all general elections which authorized the INEC to declare elections inconclusive or to schedule a rerun election where appropriate. Several arguments have arisen as to the constitutionality of the declaration by INEC. The first notorious case was the Kogi State Gubernatorial Election held on November 21, 2015, as an inconclusive election. It is against this background that the paper examines the decision of the Supreme Court in the case of James Faleke v INEC, the provision of the Electoral Act 2022 and Election Manual which affirms the legality of the INEC’s power and the correctness of the declaration of inconclusive election. It argues that the declaration of election as inconclusive is in line with the Electoral Act and the Constitution. The paper further posits the fundamental grounds or conditions upon which an election can be declared as ‘inconclusive.’ However, it suggests that there is a need to carefully thread the path of application of the provisions on inconclusive election in order to avoid a situation where it is being deployed as a manipulative tool for the benefit of the ruling party.
A Comparison of Cognitive and Social Presence in Online Graduate Courses: Asynchronous vs. Synchronous Modalities

Over the last decade, online courses have continued to expand, and students in higher education are being offered increased access to technology and communication tools in online learning programs. This action research study analyzed the impact of two distinct types of online course instruction (100% asynchronous and weekly online synchronous meetings) on learning outcomes, including cognitive and social presence, knowledge gained, and student perceptions. Study participants consisted of graduate students enrolled in online sections of a course on program evaluation. Four sections of the course were available: two included a synchronous meeting using web-conferencing, and two used an asynchronous format. A quasi-experimental design was used and included a pre-post test knowledge assessment, a modified version of the Community of Inquiry questionnaire (CoI), and end-of-course student evaluations. The mean ratings of the CoI in this study ranged from 3.75–4.60 out of 5. There was a significant difference in the cognitive presence scores for synchronous (M=4.26, SD=.529 asynchronous (M=4.47, SD=.454) conditions; t(97)=-2.07, p =.041. Our results suggest when students learn in an asynchronous format, they have a higher cognitive presence. The average scores on the knowledge pre-test were the same for both sections but post-test scores were slightly higher in the asynchronous section. Instructor ratings were high for all courses. These findings may offer valuable implications to higher education programs that have recently transitioned to online teaching modalities.
Building a Digital Educational Escape Room Using an Online Design-Thinking Process

Published: June 2023

There is increasing interest in the application of game-based learning approaches to education. Educators across a wide range of contexts are using digital games such as educational escape rooms to promote learner motivation and support skills development. Whilst the literature describes multiple game-based learning theories that can underpin such strategies, there is little practical guidance on how to integrate such conceptual elements into the design of digital educational escape rooms. This study aims to address this gap, outlining the use of an online design-thinking process to plan, build, and test a digital educational escape room. Our findings suggest that this process provides an effective way of harnessing team collaboration and innovation in the development of digital educational resources. The process provides structure for game design teams, enabling them to address complex or “messy” educational development problems. In utilising an online design-thinking process to design games for learning, we make a number of recommendations. These include taking time to establish psychological safety within the design team so as to facilitate creative team processes and supporting team members to adopt a design-thinking mindset throughout (e.g., regularly taking the perspective of the game user, and testing game prototypes early and frequently). Finally, our study offers a detailed description of how the online design-thinking process can be applied in an education context with the aim of offering guidance to educators and students who may want to design, build, and test their own digital educational escape rooms.
The Everydayness of Instructional Design and the Pursuit of Quality in Online Courses
Authors: McDonald Jason K
Published: June 2023

This article reports research into the everydayness of instructional design (meaning designers’ daily routines, run-of-the-mill interactions with colleagues, and other, prosaic forms of social contact), and how everydayness relates to their pursuit of quality in online course design. These issues were investigated through an ethnographic case study, centered on a team of instructional designers at a university in the United States. Designers were observed spending significant amounts of time engaged in practices of course refinement, meaning mundane, workaday tasks like revising, updating, fine-tuning, or fixing the courses to which they were assigned. Refining practices were interrelated with, but also experienced as distinct from, the specialized processes of instructional design or innovation that the designers also applied. Refining played a meaningful role in designers’ pursuit of course quality, both to help them achieve quality, as well as to understand what the ideal of quality meant in specific instances. The article concludes by exploring what implications these findings have for the study and practice of instructional design in the context of online course development.
