Published: May 2022

In the present paper we used a molecular data set (including mitochondrial partial 16S rRNA and COI gene sequences) to examine the genetic structure ofLepidopleurus cajetanus(Poli, 1791) (Polyplacophora, Leptochitonidae) - a distinctive shallow water chiton and member of the basal branching Lepidopleurida, which is widespread in and adjacent to the Mediterranean. The analyses of the two mt-standard marker fragments resolved two main discrete clusters reported asL. cajetanuss.s. and L. aff. cajetanus, respectively.Lepidopleurus cajetanuss.s. is widespread throughout the area under study, while the second distinct lineage apparently co-occurs on the eastern Spanish mainland coast of the Balearic Sea. This result is discussed comparing our data with those reported, in 2014, by Fernández and colleagues who describedL. cajetanusas exhibiting “a ‘chaotic patchiness’ pattern defined by a high genetic variability with locality-exclusive haplotypes, high genetic divergence, and a lack of geographic structure”. Although genetic data alone are not sufficient to draw any definitive conclusions, nevertheless we believe that present results shed new light onL. cajetanuswhich apparently shows more geographically patterned genetic structure than supposed so far.
Censorship as optimal persuasion
Authors: Kolotilin Anton , Mylovanov Timofiy , Zapechelnyuk Andriy
Published: May 2022

We consider a Bayesian persuasion problem where a sender's utility depends only on the expected state. We show that upper censorship that pools the states above a cutoff and reveals the states below the cutoff is optimal for all prior distributions of the state if and only if the sender's marginal utility is quasi‐concave. Moreover, we show that it is optimal to reveal less information if the sender becomes more risk averse or the sender's utility shifts to the left. Finally, we apply our results to the problem of media censorship by a government.
Markov distributional equilibrium dynamics in games with complementarities and no aggregate risk
Authors: Balbus Lukasz , Dziewulski Pawel , Reffett Kevin , Wozny Lukasz
Published: May 2022

We present a new approach to studying equilibrium dynamics in a class of stochastic games with a continuum of players with private types and strategic complementarities. We introduce a suitable equilibrium concept, called
Markov Stationary Nash Distributional Equilibrium (MSNDE), prove its existence, and determine comparative statics of equilibrium paths and the steady‐state invariant distributions to which they converge. Finally, we provide numerous applications of our results including: dynamic models of growth with status concerns, social distance, and paternalistic bequests with endogenous preferences for consumption.
Two‐stage majoritarian choice
Authors: Horan Sean , Sprumont Yves
Published: May 2022

We propose a class of decisive collective choice rules that rely on a linear ordering to partition the majority relation into two acyclic relations. The first of these relations is used to pare down the set of the feasible alternatives into a shortlist while the second is used to make a final choice from the shortlist.

Rules in this class are characterized by four properties: two classical rationality requirements (Sen's
Expansion Consistency and Manzini and Mariotti's
Weak WARP); and adaptations of two classical collective choice requirements (Arrow's
Independence of Irrelevant Alternatives and Saari and Barney's
No Preference Reversal Bias). These rules also satisfy some other desirable properties, including an adaptation of May's
Positive Responsiveness.
L’Espace animalier dans les maisons rurales en Algérie, territorialité vernaculaire, résurgence informelle et controverses institutionnelles
Authors: Khettabi Latifa
Published: May 2022

Cet article tente de restituer une réflexion issue d’une observation empirique de l’espace animalier dans les maisons rurales en Algérie, en considérant les processus qui interviennent dans leur consolidation vernaculaire et ceux qui participent à leur redéfinition contemporaine. L’espace animalier et son rapport à l’espace domestique sont ainsi questionnés dans la perspective de soulever les enjeux rattachés à la problématique de l’identité de l’habitat rural, au travers des persistances, des mutations et des recompositions des spatialités domestiques, dans les logements des programmes officiels de l’habitat rural en Algérie.La relation de la cohabitation homme-animal est ainsi explorée à partir d’une logique socioculturelle, en confrontation avec les logiques institutionnelles. Le propos développé vise à dresser un constat des tendances nationales pour asseoir et orienter de nouvelles perspectives de recherche sur l’architecture de l’habitat.
A Multinational Study of IS User Satisfaction and User Performance in the Intelligence Community
Authors: Zhou Yilu , Granger Mary J. , Claytor Bobby , Xue Yuan
Published: May 2022

The intelligence community (IC) makes large investments on information systems development every year. However, there is a lack of studies that evaluate their system success. This study looks into the interactions between user satisfaction and subjective and objective user performance within the IC. It differs from the previous research by having both subjective and objective measures constructed from the end-user computing satisfaction (EUCS) survey responses and system-recorded data from a multinational intelligence sharing system called Conjunctis Viribus. It generates several key findings. First, only self-rated performance is closely related to user satisfaction. Second, the subjective and objective user performances have close connections to the frequency of system use. Finally, while individual differences have positive influences on self-rated user performance, the user satisfaction is not subjective to such influences. Besides the theoretical contributions, this study also has tremendous implications to the design and use of future intelligence systems.
Cyclotomic Construction of Sparse Code Multiple Access With Improved Diversity
Authors: Al-Hamdani Hussein , Almamori Aqiel , Mohan Seshadri
Published: May 2022

A number of studies focus on sparse code multiple access (SCMA) to increase the spectral efficiency and support the massive connectivity required for future wireless communications networks. This work reports an improved design for SCMA based on algebraic number field theory and cyclotomic construction of a lattice. The proposed constellation improves the diversity of the SCMA system, which supports the probability of decoding error. We show that the proposed constellation in the uplink transmission of SCMA supports the spectral efficiency by 1 dB gain in SNR when the error probability of SCMA is 0.001 as compared to the proposals in the literature.
Reformed QoE-Based Approach in Bitrate-Adaptation for Dynamic Adaptive Streaming Systems
Authors: Abdelhafez Nada. , Hassan Mohamed S. , Landolsi Taha
Published: May 2022

With the COVID-19 pandemic, the demand for popular streaming applications is expected to soar. Ensuring high user-perceived quality correlates with higher profits for content providers and delivery systems. Dynamic adaptive streaming over HTTP (DASH) is a widely adopted video streaming standard, utilized by service providers to provide competitive quality of experience (QoE). DASH is capable of providing seamless streaming even during uncertain network conditions by switching across different video qualities and their corresponding segment bitrates. This paper introduces a non-complex algorithm that allows smooth step-like transition in the streamed video quality. The proposed approach deploys an optimization model to manage key elements that affect the user-perceived experience such as video quality, re-buffering and quality switching events. The objective is to optimize the QoE metric, which is constrained by the network throughput, segment size and buffer occupancy to continuously select the optimum bitrate levels with low complexity.

Published: May 2022

In the last decades, ICT has been promoting the creation and adoption of new learning and teaching styles. Virtual (computerized) laboratories play vital roles in learning and teaching by overcoming some limitations of conventional hands-on experiments. The number of chemistry (physical) laboratories in the Science Laboratory Technology (SLT) Department in Accra Technical University (ATU), Ghana is inadequate for the current population of students. Consequently, laboratory practice by students is very low. In this paper, we propose a virtual chemistry laboratory with simulated experiments for SLT students in ATU to support their education. To corroborate the research problem, we utilized a quantitative (questionnaire) research method, which involved a sample size of 271 SLT students (n = 271). Evaluation results of the study showed that the majority of students in the SLT Department are willing to use the virtual chemistry lab, and most of the students consider the virtual labs as an educative platform that would help them attain practical knowledge in their chemistry studies.

Authors: Prakasha GS , Benoy Aparna
Published: May 2022

The study attempts to identify what is effective online teaching from teachers and students perspectives. What are the challenges faced by teachers which hampered effective online teaching? Whether perception of effective online teaching differed based on student gender and programme of study. The study employed mixed method research design including a survey questionnaire and semi-structured interview. Study collected data from 500 students out of which 200 are boys and 300 are girls on effective online teaching. Study conducted semi-structured interview with 8 college teachers through snowball sampling. The survey revealed that almost 80% of the teachers are not effective. Girls are less satisfied with online teaching transition of teachers than boys are. Similarly, postgraduates (PG) are not as satisfied as undergraduate (UG) students are. Interview data revealed themes and subthemes on challenges of effective online teaching faced by College teachers. Overall, the perceived online-teaching effectiveness is low and further research may find the causes for the same.
Improved Artificial Bee Colony Algorithm for Multimodal Optimization Based on Crowding Method
Authors: Ma Shijing , Wang Yunhe , Zhang Shouwei
Published: May 2022

Many real-world problems can be transformed into multimodal functional optimization. Each of these problems may include several globally optimal solutions, rendering the solution of the problem progressively more difficult. In our study, we present a crowding artificial bee colony, called IABC, which exploits the concepts of crowding and explores search solutions. A crowding approach formed in niches is used to make it capable of tracking and maintaining multiple optima, resulting in good convergence of the search space with a better chance of locating multiple optima. Two new solution search mechanisms are proposed to increase population diversity and explore new search spaces. Experiments were carried out on 14 benchmark functions selected from previous literature. The results of our experiments show that our method is both effective and efficient. In terms of the quality of the success rate, the average number of optima found, and the maximum peak ratio, IABC performs better, or at least comparably, to other cutting-edge approaches.
Effect of Different Chemical Admixtures on Fresh and Hardened Properties of M30 and M40 Grade Concrete
Authors: Awchat Ganesh , Patil Laxmangauda , More Ashish
Published: May 2022

Researchers in the field of concrete technology with the application of different admixtures are always in search of suitable admixtures to improve the workability as well as the strength of any concrete grade. An attempt was made in the present research to use chemical admixtures (superplasticizers) like sulphonated naphthalene based Apple Chemie AC-MENT-ALPHA-X5, polycarboxylic ether based Fosroc Auramix 350, sulphonated naphthalene based Fosroc Conplast SP 430, modified polycarboxylate based Du-bond DUPLAST PC P 2 and modified lignosulphate based Sika PLASTIMENT BV 40 for concrete grades M30 and M40. A literature survey revealed that all identified chemical admixtures are used for 20–25% reduced water content. A study was done to compare M30 and M40 grade concrete in both fresh and hardened states, taking water reduction into account. Experimental results showed that all admixtures demonstrate good paste-up consistency of up to 1%. As the percentage of admixtures increases, there is an increase in surface pores due to more significant air entrainment. Compressive strength results of 1% admixture content for Apple Chemie, Fosroc, and Du-bond were observed to be close to their characteristic compressive strengths for both grades, but Sika and Fosroc Auramix 350 have good compressive strength with less than 1%. As the grade of concrete improves, Conplast's effect reduces, but the Du-bond and Fosroc Auramix 350 perform excellently for split tensile strength. As the grade rises, all admixtures show increasing flexural strength levels. However, Auramix 350, with a 1.5% content for M30 grade, consistently outperforms Sika, which has a 1% content. It helped to employ up to 1% of all admixtures, but Sika reveals a cost increase of 2.5 to 7.3% for 1% and 1.5% admixture additions. The study found that Fosroc Auramix 350 could be used for both grades and still have good workability and strength.
Yield Response of Rice to Added Phosphorous and Potassium Fertilizer in the Dry Zone of Sri Lanka
Authors: Kodagoda M. M. , Thrikawala S. , De Z. Abeysiriwardena D. Sumith
Published: May 2022

Purpose: Continuous application of Phosphorous (P) and Potassium (K) fertilizer over a long period in rice (Oryza sativa L) cultivation may lead to their accumulation in the soils. So, further addition of such fertilizers may be a waste in rice cultivation and also lead to environmental pollution. Thus, field experiments were carried out to study the yield response of rice to added P and K fertilizer under irrigated conditions in Low Humic Gley soils in the Dry Zone of Sri Lanka. Research Method: For the P response study, an experiment was conducted over three consecutive seasons in a rice field where P fertilizer had not been applied for 10 years before the initiation of the experiment, and for the K response study, an experiment was conducted over two consecutive seasons in a rice field where recommended K fertilizer had been continuously applied before the initiation of the experiment. Data on grain yield and yield components, milling quality, important soil properties, and soil and plant P and K contents were recorded and analyzed statistically. Findings: Grain yield, yield components and milling quality of rice did not respond to added P fertilizer over three consecutive seasons in a rice field where P fertilizer had not been applied 10 years before the initiation of the experiment. Soil P analysis indicated that enough soil P was available to maintain an adequate plant P level so that application of P fertilizer in rice cultivation can be avoided at least for about 11½ years (10 years + three seasons) without affecting grain yield and milling quality in Low Humic Gley soils in the Dry Zone of Sri Lanka while saving the cost for P fertilizer. The short-term response of grain yield in rice to added K fertilizer appeared dependent on the grain yield level obtained. No yield response of rice to added K was observed up to the yield level of about 4 t/ha. Thus, the application of K fertilizer can be avoided over two consecutive seasons without affecting grain yield in rice in Low Humic Gley soils in the Dry Zone of Sri Lanka if the yield level is 4t/ha or lower. Research Limitation: Further studies at different locations in farmers’ fields are needed to confirm the applicability of the findings of the present study in farmers’ fields in the Dry Zone of Sri Lanka. Originality/ Value: Long term (over 11½ years) P response study in rice. Such a long-term P response study in rice has not been reported to date. The short-term K response in rice is dependent on the grain yield level achieved.
Markov Chain Probability Models to Describe Bi-modal Rainfall Pattern in Sri Lanka
Authors: Wimalasiri Eranga M. , Ampitiyawatta A.D.
Published: May 2022

Purpose: Sri Lanka is a tropical island with prominent four monsoonal seasons. The rainfall pattern of the country follows a bi-modal distribution with two peaks centred on two growing seasons. Model the bimodel rainfall distribution of Sri Lanka using the Markov probability chain model was the objective of this study. Research Method: Both first and second-order Markov probability models were developed for Anuradhapura, Badulla, Hambanthota and Katunayake using daily rainfall data for 1981–2011 period and the locations were selected to cover the major parts of the country. The model fit was done using Instat Statistical Programme. Findings: Both first and second-order Markov models successfully described bi-modal distribution of rainfall. In general, both transitional probabilities in the first order (p_rd and p_rr) and three transitional probabilities of second-order except rainfall after dry day and rainy day (p_rrd) followed a bi-modal pattern with two peaks. The sum of the logs of the rainfall amount (lr) and the amount of rainfall on rainy days (r_mean) also showed two peaks for two growing seasons. In both models, stations in the dry zone showed higher agreement in the simulated rainfall. Research Limitations: Lack of continuous long-term rainfall data is one of the major limitations. Originality/ Value: It is evident that both first and second-order Markov chain probability models are very much capable to explain the bi-modal rainfall distribution in Sri Lanka.
The preventive and therapeutic role of physical activity in knee osteoarthritis
Authors: Restuccia R. , Ruggieri D. , Magaudda L. , Talotta R.
Published: May 2022

The aim of this narrative review is to discuss the results of studies investigating the role of physical activity in knee osteoarthritis (OA). We also formulated two evidence-based exercise programs that could be prescribed to patients with symptomatic knee OA or after joint replacement. The PubMed and Google Scholar databases were searched for articles related to knee OA and physical activity. A total of 86 papers written in English and published from 1957 to 2021 were selected. Adapted physical activity, even at high intensity, does not appear to trigger or exacerbate knee OA; on the contrary, it may prevent obesity or lower limb muscle weakness, both of which are considered predisposing factors for the disease. In patients already diagnosed with knee OA, scientific evidence suggests that both land-based and aquatic activities combining aerobics, strength, and endurance programs are safe and effective. Physical interventions tailored to the patient may also accelerate recovery time after knee arthroplasty. Knee OA is a painful and disabling rheumatic disease that is very common in the elderly population. Pharmacotherapy has a modest effect in controlling disease progression, possibly due to the still limited understanding of OA pathogenesis. Non-pharmacologic interventions, including dietary and lifestyle changes and physical activity, may be more effective and safer than drugs in preventing or treating knee OA.
Neurological Manifestations in COVID-19 in three Waves of the Pandemic
Authors: Kulkarni Rahul , Gupta Dulari , Pujari Shripad , Deshpande Vishal , Naphade Pravin , Deshpande Rushikesh
Published: May 2022

Background:

Though severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) virus primarily affects respiratory system, neurological involvement is well known.

Aims:

To describe the neurological manifestations of coronavirus disease 2019 (COVID-19) during three waves of the pandemic.

Methodology:

This was an ambispective observational single-centre study to describe the neurological manifestations of COVID-19 infection among inpatients from a tertiary care referral centre in Western India from March 2020 to January 2022.

Results:

Out of 14,822 patients admitted with COVID-19, 307 (2.07%) had neurological manifestations. Neurological manifestations were seen in 1.87% in first wave (onset to 10 Feb 21); 2.37% in second wave (Feb 11, 2021 to Dec 31, 2021) and 6.26% in third wave (Jan 1, 2022 to Jan 31, 2022). The most common neurological manifestations were encephalopathy (34.5%), ischemic stroke (32.1%), and acute symptomatic seizures (8.8%). Encephalopathy (p = 0.028) was more common in first wave while seizures were more common in third wave (p = 0.001). In patients with encephalopathy, hypoxia (p = 0.0001), shock (p = 0.001), renal involvement (p = 0.002), and sepsis (p = 0.033) were associated with higher mortality; while those with no systemic involvement had better survival (p = 0.0001). Among patients with ischemic stroke, 32.1% did not have any traditional vascular risk factors. These patients were 9 years younger and required 6 days less hospitalization than patients of stroke with vascular risk factors.

Conclusion:

SARS-CoV-2 produces many central and peripheral nervous system manifestations. Encephalopathy was more common in first wave while acute symptomatic seizures were more common in third wave. Encephalopathy was most common neurological manifestation with progressively higher mortality with increased number of systemic comorbidities. Ischemic stroke was seen in patients who had vascular risk factors as well as in patients without them.
Evaluation of Asymptomatic Carotid Artery Stenosis Prior to Coronary Artery Bypass Grafting - A Prospective Observational Study in North Indian Population
Authors: Bose Arghadip , Prasad Krishna , Debi Uma , Singh Harkant , Panda Prashant , Mehrotra Saurabh
Published: May 2022

Background:

Carotid artery stenosis (CAS) is an established risk factor for peri-operative neurological complications in patients following coronary artery bypass grafting (CABG). However, routine pre-surgical screening for CAS is still a matter of debate. This study was conducted to study the prevalence of asymptomatic carotid artery disease in patients undergoing CABG and to determine the predictors of significant carotid stenosis in them.

Methods:

In this prospective observational study, 112 patients, who were planned for CABG, were enrolled, and their demographic details, risk factor profile, and coronary angiogram parameters were analyzed.

Results:

Carotid stenosis was observed in 75.0% of the study population with 11.6% having unilateral and 63.4% having bilateral carotid stenosis. A total of 56.2% of the patients had mild, 14.3% had moderate, and 4.5% had severe carotid stenosis. The presence of significant carotid stenosis showed a correlation with chronic stable angina (P = 0.009), significant left main (LM) disease (P = 0.001), chronic total occlusion (P = 0.043), and coronary vessel calcification (P = 0.004). Multivariate analysis of all the predictor variables in a regression model showed that significant LM disease (Odds ratio (OR):6.5, P = 0.002) and coronary artery calcification (OR: 4.3, P = 0.024) were the only independent predictors of significant CAS in the study population.

Conclusion:

The presence of significant carotid vessel stenosis in patients undergoing CABG in the Indian population has a stronger association with the chronicity of the coronary artery disease rather than the coronary atheroma load (as determined by the modified Gensini score). The presence of significant LM disease and coronary artery calcification may be useful in detecting high-risk patients for significant CAS during the pre-surgical workup.

Published: May 2022

During the coronavirus disease (COVID-19) epidemic, there have been concerns about the impact of vaccines on people's fertility, including the fertility of those who are currently preparing for pregnancy and those who might become pregnant in future. However, there is still a lack of research on the effect of the COVID-19 vaccine on male fertility, and it is not surprising that couples and donors have concerns regarding vaccination. In this study, a retrospective cohort study was conducted to examine semen quality before and after receipt of the inactivated COVID-19 vaccine. There were no statistically significant changes in semen parameters (volume, sperm concentration, progressive motility, and total progressive motile count) after two doses of vaccine (all P > 0.05). In summary, our study updates the most recent studies on the effects of the COVID-19 vaccine on male fertility, and the information from this study could be used to guide fertility recommendations for assisted reproductive technology (ART) patients and donors.
A malignant glomus tumor in the nasal cavity responding to radiation therapy
Authors: Nam Jiho , Park Dahl , Kim Wontaek , Kim Donghyun
Published: May 2022

Malignant glomus tumors of the head and neck are extremely rare, and to our knowledge, a response to high-dose radiation has not been described previously. We report one case in an 80-year-old woman with right nasal cavity mass. Histological examination revealed sheets of atypical round glomus cells. The presence of increased mitotic activity (25 per 10 high-power fields), cellular atypism, and tumor necrosis suggested malignancy. The smooth muscle actin, vimentin, and h-caldesmon immunohistochemistry stains the tumor cells. Two cycles of doxorubicin and cyclophosphamide chemotherapy were done and the tumor size was slightly increased. Salvage radiation therapy (RT) was delivered to the primary mass over 4 weeks (50 Gy in 20 fractions) and leading to nearly complete regression of tumor. Additional investigations are warranted so that we may determine the usefulness of RT in the management of this rare tumor.
Clinicopathological characteristics of oral squamous cell carcinoma arising from oral submucous fibrosis: A systematic review
Authors: Divya Bose , Vasanthi V. , Ramadoss Ramya , Kumar A. Ramesh , Rajkumar Krishnan
Published: May 2022

Oral submucous fibrosis (OSMF) is considered to be a potentially malignant oral disorder with high risk of malignant transformation. Oral squamous cell carcinoma (OSCC) arising from OSMF has peculiar clinical and histopathological features. To assess the clinicopathological features of OSCC arising in the background of OSMF in an attempt to identify the patients with OSMF who are at increased risk of developing OSCC. A systematic review was performed based on PRISMA guidelines to include articles published until May 2021 in English, relating the clinicohistopathological characteristics of OSCC arising from OSMF (OSMF-OSCC) or OSMF associated with OSCC (OSCC-OSMF). All the eligible articles were analyzed and relevant data were extracted. Seventeen articles were included for systematic review after following strict inclusion and exclusion criteria. The malignant transformation rate of OSMF-OSCC ranged from 1.9 to 9.13 and the prevalence of OSCC-OSMF ranged from 2.8 to 66. The mean age of the patients ranged from 36.6 years to 47.2 years and buccal mucosa was the common site to be affected. Majority of the OSCC-OSMF was well-to-moderately differentiated and majority of them did not metastasize to the lymph nodes. OSCC associated with OSMF presents at a younger age with early tumor stage, better differentiation, and better prognosis when compared to OSCC not associated with OSMF. However, more multicentric prospective studies with large sample size are required to determine the true biologic behavior of OSCC arising in the background of OSMF to establish less aggressive treatment strategies considering them as a separate entity.

Published: May 2022

La calidad del agua en la provincia Cotopaxi ha sido objeto de análisis debido a la utilidad de este recurso para la población, lo cual sirve como punto de referencia para la detección de los niveles de contaminación en el río Illuchi. El objetivo del estudio fue determinar el índice de calidad del agua mediante parámetros físicos, químicos y microbiológicos. En los dos primeros se tuvieron en cuenta variables abióticas; mientras que en el tercero se trabajaron variables bióticas, específicamente la identificación taxonómica de diatomeas presentes en los sistemas acuáticos. Se tomaron tres puntos de muestreo: laguna Salayambo (P1), hacienda Noelanda (P2) y barrio Saragosín (P3), identificándose 31 especies de diatomeas epilíticas a lo largo del río. El cálculo del índice de calidad del agua arrojó valores para el punto 1 de 70.18, cuya calificación es regular y de tipo oligotrófico, el punto 2 un valor de 52.2, su estado regular de tipo ?-mesotrófico y el punto 3 de 46.87 con una calidad mala de tipo ?–mesotrófico. Se pudo concluir que existe una relación entre las diatomeas y la calidad del agua; además se evidenció el incremento de la contaminación debido a la agricultura, ganadería y los asentamientos humanos.

EVALUATING UNIVERSITY PEDAGOGY: TEACHER AND STUDENT PERSPECTIVES
Authors: Aikaterini Toka , Gioti Labrina
Published: May 2022

The purpose of the paper is to investigate the field of University Pedagogy and specifically the teaching characteristics and practices adopted in the postgraduate programs of the Alexander Technological Educational Institution (TEI) of Thessaloniki (now International Hellenic University). To this end, we conducted a mixed methodology research (triangulation) by implicating both the students and the teachers of the institution. The data collection methods were: 7 semi-structured interviews with the teaching staff and student questionnaires (n=98). Results show that a lot of the features of teaching are in line with the principles of student-centered and adult learning. Students appear to be satisfied with the teaching and the overall learning experience. They state that the climate is positive, the teachers friendly and accessible. However, despite the use of many teaching techniques (discussion, brainstorming, working in groups), the results show that enriched presentation remains the technique most frequently used. Finally, a significant correlation was found between students' academic background (major) and the way they perceive teaching (teacher-centered or student-centered).

SUSTAINABLE DEVELOPMENT AWARENESS OF SOCIAL SERVICE UNDERGRADUATE STUDENTS
Authors: Kucuk Arzu
Published: May 2022

This study aimed to determine the sustainable development awareness of the students studying in the social service program and to explain the factors that predict it. A survey method was used. Data were gathered with a scale called the "Sustainable Development Awareness Scale” developed by Ozturk-Demirbas (2011). Participants consisted of 55 students studying in the second year of the social service undergraduate program of a state university in Turkey. The measurement tool was applied to the students in an online environment in the first quarter of 2022. It was concluded that sustainable development awareness levels of social service undergraduate students are high in terms of environmental ethics, social factors, and total points and medium in terms of environmental-economic as measured in pre-service teachers in many other studies. Social service students' awareness of sustainable development was higher in the first two dimensions of the scale and lower in the third dimension when compared to the others. It has been revealed that the experiences during the normal flow of life do not have sufficient effect on this awareness. It is an important necessity for students to take action so that they can have concrete experiences in social responsibility projects and gain awareness of sustainable development.

The purpose of this research was to examine the effect of teaching life skills through the volleyball passing skill, of 44 primary school female children and their perceived satisfaction with the program. The sample was randomly assigned into two groups. The life skills group (LSG, n= 23) and the control group (CG, n= 21). All participants followed a six-week practice program aiming the passing skill learning. For the participants of LSG the program was combined with the components of goal setting, problem-solving and positive thinking. The control group received typical teaching and feedback provided by the PE teacher. All participants were evaluated in three measurements: pre-test, post-test and retention test. A qualitative evaluation (five main elements) of the passing technique, which was recorded by the digital camera, was used. Also, a common format for evaluating life skills knowledge perceptions and transfer (10-item questionnaire), which was developed in the Greek population by Papacharisis (2004) based on the work of Hogan (2000), and also a questionnaire for the perceived satisfaction of the students was used (Alexandris, Tsorbatzoudis & Grouios, 2004a, 2004b). Anova repeated measures show that participants of the LSG improved passing skill (p<.05) and showed a positive reception of the program by the students who learned interesting and useful things for their life in general, transferable to other aspects in their life, besides sports. The results of the study support the effectiveness of the life skills program that integrated volleyball passing skill learning, life skills improvement and participants’ perceived satisfaction of the program.

Authors: Navei Nyamawero , Akyem Samuel Yeboah , Diabour Kwame Kyere
Published: May 2022

Formal education becomes most authentic, inclusive, and learner-centred when Art is at its forefront. The Arts provide learners with authentic learning experiences that engage their minds, hearts, hands, and entire bodies. The general relevance of Art education for learners with special educational needs has been variously and solidly argued by previous studies. However, much is not known about the creative artefacts of learners with special educational needs. The focus of this qualitative case study was to artistically appreciate selected visual artefacts produced by hearing-impaired pupils of Tetteh Ocloo State School for the Deaf located at Adjei-Kojo, a suburb of Accra in Ghana. Adopting triangulation of instruments (semi-structured interviews, field observation & photography), the study gathered in-depth data from sixteen (16) purposively sampled respondents with findings analysed using qualitative descriptive tenets. The study ascertained that the Creative Arts subject is dedicatedly taught in Tetteh Ocloo State School for the Deaf by Art specialist teachers. As a result, the study observed that the hearing-impaired primary pupils of Tetteh Ocloo State School for the Deaf were able to produce intriguing Visual artefacts (ranging from drawings/painting, clay work & papercraft). Aesthetic appreciation of some of the artefacts revealed that the works represent the oral accounts of the pupils’ worldview of salient experiences in their immediate social and physical environments. It is recommended that the Art specialist teachers of Tetteh Ocloo State School for the Deaf should continue to teach the Creative Arts subject with dedication as this would nurture and inculcate the needed creative, innovative, and inventive skills onto the pupils for responsible adulthood.

Sowa-rigpa is known as Amchi or Buddhist medicine or Tibetan system of medicine which is primarily based on Buddhist philosophy. It is the fact that basic concepts of Sowa-Rigpa and Ayurveda are almost same and it seems that there is inter-relation among these two traditional systems of Indian Medicine. The description of Tridosha, Panchamahabhuta, seven Dhatus, three Malas, week wise embryological development are same. In Sowa-Rigpa, it has been mentioned that we all are sick due to ignorance as according to Buddhist philosophy, Ignorance is the cause of sufferings. The relation between ignorance and suffering as per the Sowa-Rigpa may be the unique concept which may show the path for human-beings to eradicate all human sufferings i.e., ultimately to walk on the path of Nirvana which is the goal of Buddhist philosophy and Moksha according to Ayurveda.
