Research on the Influence Maximization Problem in Social Networks Based on the Multi-Functional Complex Networks Model
Authors: Bin Sheng , Sun Gengxin
Published: May 2022

Most of the existing influence maximization problem in social networks only focus on single relationship social networks, that is, there is only one relationship in social networks. However, in reality, there are often many relationships among users of social networks, and these relationships jointly affect the propagation of network information and its final scope of influence. Based on the classical linear threshold model and combined with various relationships between network nodes, in this paper MRSN-LT propagation model is proposed to model the influence propagation process between nodes in multiple relationships social networks. Then, MRSN-RRset algorithm based on reverse reachable set is proposed to solve the problem of low computational performance caused by greedy algorithm in the research process of traditional influence maximization. Finally, the experimental results on real data sets show that the proposed method has better influence propagation scope and greater computational performance improvement.

Published: May 2022

The strong vacuum ultraviolet (VUV) radiation absorption and energy transfer mechanism is detected in SrF2: Gd3+, Eu3+ fluoride phosphor. The phosphor is synthesized by a wet chemical method followed by reactive atmospheric process (RAP). The Powder XRD analysis shows structural purity. The photoluminescence characteristics of SrF2:Gd3+, Eu3+ phosphor is studied using the remote access of 4B8 window (VUV beamline) of the Beijing Synchrotron Radiation Facility (BSRF) China. In this paper the mechanism of Energy transfer from the Gd3+ to Eu3+ through the cross relaxation process is investigated. The down-conversion of energy from VUV (142 nm) to visible with quantum efficiency (QE) around 124% has been detected. The PL excitation and emission characteristics of the prepared phosphor advocates it as a prominent material for the applications in mercury free fluorescent lighting (MFFL) & Plasma Display Panel.

Published: May 2022

Lotus-type porous materials (LTPMs) are considered as a new category of engineering materials. They are porous materials characterized by long, straight, unidirectional cylindrical pores, and are obtained via unidirectional solidification from a melt under hydrogen and argon atmospheres. The anisotropic pore morphology of lotus-type materials results in the anisotropy of their mechanical and physical properties. This study aims at investigating the effect of cross-sectional pore shapes on the effective Young's modulus (EYM) of LTPMs. The representative volume element-based finite element homogenization method was used to compute the effective bulk and shear moduli. Subsequently, the EYM was deduced from the effective bulk and shear moduli. The numerical results of the circular pores were validated by comparing them with experimental results. Because the results indicated that the EYM is extremely sensitive to the variation in the pore shapes, a formula for estimating the EYM of LTPMs by considering the pore shapes was developed and validated.

Published: May 2022

Purpose: Adoption of new technology in the agricultural sector is low. This is similar to the condition in many other sectors as well. Many studies have been conducted to find out reasons for this issue. While some studies have identified similar factors affecting the decision to adopt a technology, some studies revealed factors which were uniqe to their study. Therefore, identification and compilation of these factors will support future studies and researchers.Research Method: An analysis of literature on technology adoption was conducted. Literature originated from numerous sources spanning almost 50 years were taken for the study. The factors identified by different studies were then compiled for this review paper.Findings: The factors identified can be mainly categorized into three; (1) factors related to the user, such as farm size, income, prior experience, gender, education level, and age; (2) factors related to the technology, such as affordability, availability, compatibility, complexity, trialability and observability; (3) institutional factors, such as access to extension services, inputs, markets and credit facilities. The review findings reveal that adoption is a collective and interactive effect of some or all factors. Thus, identification of priority factors and a holistic approach need to be considered to ensure greater adoption.Originality/ Value: This compilation will support practitioners in technology dissemination for proper identification of factors affecting technology adoption, and future research on technology adoption and  diffusion

The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate (HoLEP) in patients presenting benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in Shanghai Ninth People’s Hospital (Shanghai, China) between January 2009 and December 2018. According to the preoperative International Prostate Symptom Score (IPSS), all patients whom we analyzed were divided into Group A (IPSS of 8–18) and Group B (IPSS of 19–35). Peri- and postoperative outcome data were obtained during the 1-year follow-up. IPSS changes were the main postoperative outcomes. The postoperative IPSS, quality of life, peak urinary flow rate, postvoid residual, and overactive bladder symptom score (OABSS) improved significantly. The IPSS improved further in the group with severe LUTS symptoms, but the postoperative IPSS was still higher than that in the moderate LUTS group. OABSSs showing moderate and severe cases after follow-up were more frequent in Group B (9.1%) than in Group A (5.2%) (P < 0.05). There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores, and the medication costs, as well as the total costs, were significantly higher in Group B. In this retrospective study, HoLEP was an effective treatment for symptomatic BPH. For patients with LUTS, earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

Published: May 2022

Background and objectives

Microbial bioconversion of phytosterols produces many compounds especially steroid intermediate hormones. One of the most important transformation reactions is side chain degradation of sterols especially phytosterols β-sitosterol to androstenedione (AD), and androstadienedione (ADD). These compounds are considered to be critical intermediates in the preparation of testosterone, estrogen hormones. The main objective is to study the bioconversion of some agriculture wastes as a cheap source of phytosterols to more valuable products AD and ADD.

Materials and methods

In the present study, phytosterols of some agriculture products especially soybean, rice bran, and wheat bran were used as a substrate for the production of both AD and ADD using locally isolated bacterial strain. Different physiological and biochemical factors were tested as well as qualitative and quantitative estimation of the transformation products were carried out according to a previously recorded method.

Results and discussion

The results showed that screening experiments were carried out to investigate the ability of 12 bacterial isolates to transform plant agriculture wastes phytosterols into steroid hormone intermediates AD and ADD. The results also indicated that only four strains possess this ability. One of which was selected to complete this study according to its high AD and ADD productivity. Different physiological and biochemical tests involving catalase, oxidase, coagulase, indole production, urease, citrate and voges-proskauer, type of the agriculture waste, moisture content, parentage of the waste as well as some additives were tested. The results showed that the best bioconversion (3.98 and 3.37 mg/100 ml of both AD and ADD, respectively) were obtained by using soybean − what bran mixture at a ratio of 1 : 1. Qualitative and quantitative analyses of the transformation products were investigated. The phylogenic analysis was carried out and the results indicated that the new strain referred to is Ochrobactrum anthropi, which is first recorded to be a phytosterol transformer.

Conclusion

The study has indicated that the newly isolated bacterial strain Ochrobactrum is first recorded to perform the side chain degradation of phytosterols presented in soybean and wheat bran to AD and ADD under the above-selected fermentation conditions.
Effectiveness and cost-effectiveness of trastuzumab emtansine in women with HER2-positive locally advanced or metastatic breast cancer
Authors: Yeh Yingchih , Chen Chiehfeng , Ko Yu
Published: May 2022

Background:

Trastuzumab emtansine (T-DM1) is a human epidermal growth factor receptor-2 targeted antibody-drug conjugate that contains a monoclonal antibody, trastuzumab, covalently linked to DM1, a small molecule cytotoxin.

Methods:

We conducted a systematic review and meta-analysis of published trials to examine the efficacy and safety of T-DM1 for patients with HER2-positive metastatic breast cancer. In addition, we systematically reviewed existing economic evaluations of T-DM1. An electronic literature search of online databases (Medline, CENTRAL, and Embase) was performed. Randomized controlled trials that compared T-DM1 with other active treatment agents were eligible for inclusion. In addition, studies that involved T-DM1 as one of the treatment comparators in an economic evaluation were included. Four trials with a total of 2462 participants were included in this meta-analysis.

Results:

Pooled results showed T-DM1 substantially improved overall survival (hazard ratio [HR], 0.75; 95% confidence interval [CI], 0.67–0.85; I2 = 0%) and progression-free survival (HR, 0.67; 95% CI, 0.52–0.85; I2 = 75%). In addition, T-DM1 showed greater association with severe thrombocytopenia and liver dysfunction than other regimens, but a lower rate of neutropenia, leukopenia, febrile neutropenia, asthenia, and diarrhea. All four trials included in the meta-analysis overall had a low risk of bias. Two cost-utility analyses involving T-DM1 were identified, and the overall quality was high.

Conclusions:

T-DM1 is effective for the treatment of patients with HER2-positive metastatic breast cancer, and it demonstrates a tolerable safety profile compared with other active controls. Little evidence was available regarding the cost-effectiveness of T-DM1 so no conclusions can be drawn.

Authors: Kumar Rajesh , Pasricha Rajesh , Gupta Manoj Kumar , Ravi Bina
Published: May 2022

Introduction:

Breast cancer remains a leading cause of unintended death among Indian women. Cancer treatment-induced pain, fatigue, nausea/vomiting, body image, and sexual problems could affect the patient psychosocial well-being and quality of life (QOL). The study aims to determine the QOL and psychosocial well-being among women with breast cancer.

Materials and Methods:

A cross-sectional survey completed by 244 women with breast cancer at a tertiary level teaching hospital. The European Organisation for Research and Treatment of Cancer QOL Questionnaire C30, the Breast Module (QLQ-BR23), and the Hospital Anxiety and Depression Scale (HADS) is used to measure the QOL, and psychological well-being, respectively. Appropriate descriptive and inferential statistics are applied to compute the results.

Results:

The total number of women with breast cancer interviewed was 244, with a mean age of 45.06 (standard deviation ± 11.17) years. The mean global health score was 70.97 ± 15.63. As per the QLQ-C30 scale, “physical functioning” scored the highest (70.54 ± 22.00), and “role functioning” reported the lowest (49.45 ± 36.15) mean score. Further, on the QLQ-C30 symptoms scale, “appetite loss” (45.09 ± 35.09) was the worst reported symptom, followed by “nausea and vomiting” (34.97 ± 38.39). On the BR-23 scale, body image said (68.42 ± 22.28) higher score than other domains and experience of arm-related problems (43.80 ± 26.06) were more frequently reported symptom in women. As per the HADS scale, 24.6% and 36.1% of women were in moderate anxiety and depression, respectively. The mean HADS score was 14.39 ± 5.82. Findings on predictors for the individual patient remained the same as that earlier published literature.

Conclusions and Recommendations:

Women with breast cancer have an overall good QOL and poor psychosocial well-being. However, using a holistic approach, including identifying psychological problems and their time management, signifies the need for the studied population.

Purpose The treatment of male breast cancer (MBC) has been extrapolated from female breast cancer (FBC) because of its rarity despite their different clinicopathologic characteristics. We aimed to investigate the distribution of intrinsic subtypes based on immunohistochemistry, their clinical impact, and treatment pattern in clinical practice through a multicenter study in Korea.Materials and Methods We retrospectively analyzed clinical data of 248 MBC patients from 18 institutions across the country from January 1995 to July 2016.Results The median age of MBC patients was 63 years (range, 25 to 102 years). Among 148 intrinsic subtype classified patients, 61 (41.2%), 44 (29.7%), 29 (19.5%), and 14 (9.5%) were luminal A, luminal B, human epidermal growth factor receptor 2, and triple-negative breast cancer, respectively. Luminal A subtype showed trends for superior survival compared to other subtypes. Most hormone receptor-positive patients (166 patients, 82.6%) received adjuvant endocrine treatment. Five-year completion of adjuvant endocrine treatment was associated with superior disease-free survival (DFS) in patients classified with an intrinsic subtype (hazard ratio [HR], 0.15; 95% confidence interval [CI], 0.04 to 0.49; p=0.002) and in all patients (HR, 0.16; 95% CI, 0.05 to 0.54; p=0.003).Conclusion Distribution of subtypes of MBC was similar to FBC and luminal type A was most common. Overall survival tended to be improved for luminal A subtype, although there was no statistical significance. Completion of adjuvant endocrine treatment was associated with prolonged DFS in intrinsic subtype classified patients. MBC patients tended to receive less treatment. MBC patients should receive standard treatment according to guidelines as FBC patients.

Internationale Studierende in Deutschland: Perspektiven aus Hochschulforschung und Hochschulpraxis
Authors:   Deutscher Akademischer Austauschdienst (DAAD), Kercher Jan
Published: May 2022

Seit dem Beginn des Jahrtausends ist die Zahl der internationalen Studierenden in Deutschland rasant gestiegen: Von rund 126.000 im Wintersemester 2000/01 auf rund 325.000 im Wintersemester 2020/21. Ihr Anteil an allen Studierenden stieg im selben Zeitraum von sieben auf elf Prozent. Selbst die Corona-Pandemie ab dem Frühjahr 2020 führte nicht dazu, dass die Gesamtzahl der internationalen Studierenden in Deutschland abnahm, anders als in vielen anderen wichtigen Gastländern internationaler Studierender weltweit. Es ist somit davon auszugehen, dass Deutschland auch in Zukunft das wichtigste nicht-englischsprachige Gastland internationaler Studierender weltweit bleiben wird; nur die USA, das Vereinigte Königreich und Australien ziehen derzeit mehr internationale Studierende an. Vor diesem Hintergrund thematisieren die Beiträge des Sammelbands Ansätze zur Steigerung der Integration und des Studienerfolgs internationaler Studierender im Studienverlauf, die Einsatzmöglichkeiten digitaler Unterstützungsinstrumente, die Bedeutung und Förderung von Deutschkenntnissen und Deutschlernen sowie die spezifische Unterstützung von Studierenden mit Fluchthintergrund. Anders als bei klassischen wissenschaftlichen Publikationen wird hierbei stets ein enger Praxisbezug gewährleistet, zum einen durch eine möglichst verständliche und praxisnahe Sprache, zum anderen aber auch durch die Beteiligung der Hochschulpraxis selbst. Es ist daher kein Zufall, dass die Mehrzahl der Beiträge des Sammelbands von Hochschulpraktikerinnen und -praktikern stammen, ohne dabei die Perspektive der Hochschulforschung auszuklammern.

Published: April 2022

The Zubair Formation is a prolific oil reservoir in several southeastern Iraq oil fields. The formation comprises thick sandstones with interbedded shales and siltstones of Lower Cretaceous age (Hauterivian to lower Aptian). The environment of the Zubair Formation consists of fluviodeltaic, deltaic, and marine sandstones. In southern Iraq, the area is subdivided into informal members (oldest to youngest). The Lower Shale, lower sand, middle shale, main pay upper sand, and the upper shale. At the W oilfield, the main pay member is an oil producer. The thickness is of the main reservoir about 100 meters thick. A recent study focused on the Main Pay upper sand, which is divided into three informal units. The upper unit H and lower unit L reservoir units are connected by shale intervals (K unit) that extend throughout the field area laterally. There exist four depositional lithofacies of Zubair Formation fluvial, channel, mouth bar, and prodelta depositional lithofacies. Four Facies were defined according to gamma-ray sandstone, shaly sand, sandy shale, and shale Facies. The Zubair formation has four types of rocks (RRT1, RRT2, RRT3, and RRT4) due to heterogeneity. The RRT1 is characterized by 10%-25% porosities and 10-1000 mD permeability. The RRT2 has a similar porosity range to RRT1, 15%–25%, but an order ofmagnitude lower permeability range from 10-100 mD. RRT3 is considered to have high porosity and low permeability is thought to have great storage but poor flow potential. RRT 3 is characterized by 6%-15% porosities and <10 mD permeability. Meanwhile, RRT4 is considered to have low porosity and low permeability. Various rock types showed in the H unit due to heterogeneity, which composed this unit. The K unit unveiled RRT4 due to shale Facies. The rocks types common of unit L are RRT1 and RRT2 where the L unit mostly ranged from sandstone to shaly sand Facies.

Published: May 2022

In the current study, the representations of kindergarten prospective teachers on the rainbow formation phenomenon as well as their interest in implementing rainbow-related activities in their teaching were explored. This study is part of a research perspective that aims to document the difficulties of Early Childhood Education teachers in Physical and Biological Sciences. Rainbow topic was chosen as on the one hand it is often included in curricula along with various other visual phenomena and on the other hand, there is no related research that focuses on teachers’ views about this phenomenon. The research was qualitative and exploratory in nature and was conducted through a semi-structured interview. From data analysis it was found that the kindergarten prospective teachers of the sample have structured mental representations about rainbow which are far from school scientific knowledge. At the same time, they consider the rainbow to be an interesting topic for developing teaching activities in the classroom.

THE MEDIATING EFFECT OF INFORMATION AND COMMUNICATION TECHNOLOGY LEARNING ON THE RELATIONSHIP BETWEEN SOCIAL MEDIA USAGE AND INFORMATION-SEEKING BEHAVIOR OF STUDENTS
Authors: Navales Jolina Maureen P. , Dequito Estela R.
Published: May 2022

This study aimed to determine the mediating effect of information and communication technology learning on the relationship between social media usage and students' behavior from the Bachelor of Science and Technology program at the University of Mindanao. A stratified random sampling method was used, with 300 students serving as respondents. The results of a non-experimental quantitative mediation analysis using a validated questionnaire, mean, regression techniques, and Pearson r revealed a significant relationship between social media usage, behavior, and information and communication technology learning. Results of the study showed that students' level of social media usage was moderate. The study also revealed that students' level of information-seeking behavior was moderate. Further, there was a partial mediation on the effect of information and communication technology learning on the relationship between social media usage and information-seeking behavior. As a result, one of the reasons why social media usage can influence information-seeking behavior is information and communication technology learning. Nevertheless, it cannot wholly account for the relationship between the two variables.

LEARNING TO TEACH IN THE ERA OF UNCERTAINTIES: CHALLENGES AND LESSONS LEARNT BY STUDENT TEACHERS DURING COVID-19 PANDEMIC IN UGANDA
Authors: Omara Polycarp , Akwongo Betty
Published: May 2022

The global impact of the COVID-19 pandemic is not only being felt by different social classes of people, but also across levels of education systems. There was a paradigm shift from the traditional teaching approaches to a more flexible one, including remote teaching. This crisis uncovered the many challenges in the education system such as access and lack of supportive environments for both teachers and learners. The teacher trainees were greatly affected as they could hardly complete their teacher training programme in time. The purpose of this study was to investigate student teachers’ perception of teaching during the COVID-19 pandemic. Specifically, to explore challenges faced by student teachers; document lessons learnt and coping strategies improvised while teaching during the COVID-19 pandemic. A concurrent mixed method design was adopted. Both quantitative and qualitative data were collected from 46-year three student teachers of Muni University. Data were collected using student teachers’ reflective journals and reflective meetings. Challenges experienced by student teachers were related to placement, supervisor-supervisee relationship, inadequate support from school authorities, inadequate skills in classroom room management and time management. Student teachers adopted coping strategies like teamwork, collaborative and adaptive skills, classroom and discipline management. Four categories of lessons learnt were adaptiveness, collaboration, creativity and uniqueness of learners. They learnt how to incorporate modern approaches including those embedded in Bloom’s taxonomy. The study recommended that teacher training institutions should ensure adequate and wholistic preparation of student teachers prior to school practice; school practice supervisors should treat school practice supervision as a non-judgemental exercise meant to enhance student teachers’ professional growth, and school authorities should provide required materials and mentorship to student teachers.

LECTURERS’ PERCEPTIONS OF STUDENT ENGAGEMENT AND THEIR ROLE IN SUPPORTING IT
Authors: Montenegro Aida
Published: May 2022

A positive relationship between emotional engagement and teaching support was reported in a previous quantitative study on students’ perceptions of student engagement in four introductory lecture-based courses at four different German universities. The present qualitative research was designed to collect data from the four German male lecturers who participated in the previous study to explore their perceptions of student engagement and their role in supporting it. The lecturers of varying degrees of experience were observed while lecturing and subsequently interviewed to analyze their motivating teaching behavior. The analysis highlighted that lecturers (1) positioned themselves as committed professionals with a sense of ownership, (2) attributed positioning to students as social scientists, and (3) communicated messages characterized by supporting autonomous motivation. The lecturers implemented motivation strategies to engage their students who exhibited a preference for intentional silence. Certain characteristics of the students attending introductory level courses in Germany, such as having gained self-regulation skills at upper secondary school, highlight the importance of establishing specific goals before attending higher education courses.

Entrustable Professional Activities (EPAs) can be defined as a unit of professional practice that can be entrusted to a trainee after they have obtained adequate competency. EPAs integrate multiple competencies from several domains and are very useful in designing competency-based curricula. Using EPAs to design medical curricula has been widely described, but their application to curriculum design of other health-related undergraduate programs is scarce. This manuscript critically assesses an educational planning experience of using EPAs to simultaneously design three healthcare undergraduate programs (nursing, biomedicine and psychology) at Faculdade Santa Casa BH, Minas Gerais, Brazil. We present the EPAs for each program, curricula frameworks, educational strategies, and assessment methods. Expert groups of professors and educational specialists defined the core professional activities that would be directly assessed and entrusted to trainees from the three different programs. The expert group then defined the required knowledge, skills, and attitudes for each EPA and selected the appropriate assessment tools to be used in entrustment decisions. The expected entrustment level for each training phase guided the course’s distribution of core and elective courses. The experience of designing a curriculum using EPAs was successful and helped focus on the core activities of each profession. It also provided an opportunity to reflect upon formative and summative assessments throughout the course bringing the challenge of reorienting our teaching practices and assessment approaches. Designing undergraduate curricula of health-related professions using EPAs is feasible and might help operationalize competency-based curricula.

Three research questions guided the study. Purposive random sampling technique was used to select 500 Senior Secondary 1 and 2 (SS1 and SS2) Physics students from forty-four (44) schools in three Local Government Areas of Rivers State, which are Obio-Akpor Local Government Area, Port Harcourt Local Government Area and Gokana Local Government Area. The research instrument was a validated researcher-developed questionnaire titled ‘Students’ Physicsphobia Questionnaire’ with a reliability coefficient of 0.79 obtained using the Cronbach alpha formula. The findings of this study showed that Physicsphobia exists in students. The study further revealed some of the causes of Physicsphobia to be rumors and misleading information about Physics, teaching method, the uninteresting nature of physics lessons, as well as abstract, difficult and mathematical nature of Physics. The study also revealed some of the effects of Physicsphobia in students to be anxiety, rapid heartbeat, frustration, depression and a feeling of leaving Physics class. It was then recommended that conscious effort should be made to paint a better picture of physics, especially for students who are about to start the study of Physics.

A CHILDREN’S FESTIVAL DURING THE COVID-19 PANDEMIC
Authors: Riga Vassiliki
Published: May 2022

The DESECE Children’s Festival was launched in 2010 at the Department of Educational Sciences and Early Childhood Education (DESECE) of the University of Patras. It is organised annually by the DESECE students in collaboration with their professors and comprises a variety of educational and creative workshops for children of a preschool age. To date, it has hosted over 10,000 children, and 300 institutions and schools, and has expanded its activities into other areas as well, such as teacher training. In 2020, in response to the COVID-19 pandemic and in order to support the children, parents and teachers, the Children’s Festival sought alternative ways of carrying out the event, creating online activities and a thirty-hour virtual festival over five days. This unprecedented experience offered great satisfaction to the Festival’s Organising Committee, which managed the crisis, and to the volunteer students, who improved their digital skills and gained experience in e‑learning. At the same time, it offered the possibility to people, both in Greece and abroad, to participate in the event, which until then had been limited to local society.

CRITICAL EDUCATION AND INTERCULTURALISM IN THE TEACHING OF CITIZENSHIP EDUCATION: THE CASE OF GREEK PRIMARY SCHOOL EDUCATION
Authors: Vavitsas Theodoros
Published: May 2022

The present research aims to investigate Interculturalism and the Emancipatory Interest in the textbooks of Citizenship Education in the Greek Primary School. Applying Habermas’ theory of Emancipatory Knowledge Interest as a theoretical framework, the research methodology used is interpretive content analysis. The results of the research showed that Intercultural Education is promoted by the textbooks of Citizenship Education in the Greek Primary School, mainly by the one taught in the 6th class, while the Emancipatory Interest is, also, reflected in many cases. The perspective of valorizing the Emancipatory Knowledge Interest derives not only from the textbook of the 6th grade itself, but also from the teacher's contribution, which is to be evaluated as equally crucial. Finally, although the subject of Citizenship Education contributes, clearly, to the reproduction of the dominant ideology, it seems that if we study the content of the textbooks in-depth and, in particular, the concepts it discusses, namely, freedom, justice, equality or solidarity, we can, definitely, identify opportunities for emancipation.

REACHING THE ISOLATED EFL PREP-CLASS STUDENTS VIA GROUP VIDEO TASKS DURING EMERGENCY REMOTE TEACHING: STUDENTS’ PERCEPTIONS
Authors: Yanar Berna Saygıner , Şahinkayası Hamide
Published: May 2022

Due to Covid-19 pandemic precautions, the 2020-2021 academic year was a radical shift from face to face education to online at all levels throughout the world. Students who were newly enrolled to their university from different regions of Turkey started their lessons as EFL Prep-class students without meeting their classmates, feeling isolated. In order to make them feel in a classroom, create their sense of belonging and the rate of participation in lessons during emergency remote teaching, online group video tasks were designed for an EFL prep class. This study aims to investigate students’ perceptions of the effects of online collaborative group video tasks on their English and some 21st-century skills. It has a sequential explanatory design that is a type of mixed-method research. The students were given three group video tasks during the semester. After they finished the tasks, a 4-point Likert-type scale questionnaire was administered to the whole class, groups’ videos were analysed, and in order to get students’ perceptions in-depth, semi-structured online interviews were held with six voluntary students. It was found out that group video tasks through online collaboration were beneficial for the development of the use of English, writing, pronunciation and speaking skills, helped students develop a sense of belonging to their class. These tasks made students learn how to make a presentation, helped them gain some digital skills such as using video-maker programs, as well. It was also found out that Microsoft Teams was a student-friendly platform for online classes.

FACTORS AFFECTING BALL VELOCITY IN WELL-TRAINED FEMALE HANDBALL PLAYERS
Authors: Canli Umut , Kurt Cem
Published: May 2022

In this study, we aimed to analyze whether a relationship between anthropometric and physical performance characteristics and ball velocity in different throwing techniques of well-trained female handball players exists. Twelve well-trained female handball players (age, 22.47±4.57 years; body mass, 66.70±11.05 kg; height, 167.33±7.41 cm; handball experience, 9.91±3.47 years) from a local team that participated in Turkey’s First Women’s Handball League were recruited in this study. Anthropometric measurements, body indexes, physical performance, and ball velocity were evaluated in all subjects. A positive relationship was found between ball velocity in 9-m throw after three steps a jump and arm span, bi-iliac breadth, and bi-acromial breadth (r2=0.49; p=0.03, r2=0.50; p=0.03 and r2=0.57; p=0.02, respectively) as well as between ball velocity in 9-m throw after three steps and a jump and Monourier index (r2=0.52; p<0.04). Ball velocity in 9-m throw after three steps and a jump was negatively related to Cormic index (r2=-0.52; p<0.04). Multiple linear regression analysis showed that all performance parameters affect neither the 7-m throw (R=0.85, R2=0.73; F(4-7)=1.61; p>0.33) nor the 9-m throw three steps after and a jump (R=0.88, R2=0.77; F(4-7)=1.96; p>0.26). However, a moderate positive relationship between 9-m throw after three steps and a jump and grip strength (r=0.54; p=0.03) and vertical jump height (r=0.53; p=0.03) was noted. Neither 7-m standing throw nor 9-m throw after three steps and a jump correlated with other variables. Arm span, bi-iliac breadth, bi-acromial breadth, Monourier index score, Cormic index score, vertical jump height, and grip strength may have a positive or negative effect on 9-m throw after three steps and a jump in well-trained female handball players. The results of this study may be useful in the identification of handball skills.

Recurrent miscarriages are characterized as three or more spontaneous abortions in a row before the 20th week. In the majority of instances, genetic factors, immunological and endocrine factors, infection, and unknown causes are the most common causes of first trimester abortion. Hormonal therapy, heparin injection, and immunotherapy are the available treatments. In this case study, the patient had three abortions during the first trimester. Because all of the tests came out normal, the diagnosis of unexplained recurrent abortions was made. For 40 days before conception, the patient was treated with Ayurvedic medications such as Indukanta Ghrita, Phalghrita. The patient was conceived with these drugs, and later Phalaghrita and other medicines were given for the duration of the pregnancy. Ayurvedic medicine is an effective way to deal with recurring abortions.

Published: May 2022

Neural variation of the brachium constitutes a significant anatomical and clinical entity. The absence of Musculocutaneous Nerve is occasional in humans and accordingly there may be unforeseen clinical implication regarding the atypical innervations of musculature otherwise supplied by the Musculocutaneous Nerve. The present study is an absence of Musculocutaneous nerve observed during our routine educational dissection, where the lateral cord of brachial plexus took over the area of supply of Musculocutaneous Nerve by giving both the muscular and sensory branches. Knowledge of these variations is important in surgeries and during the administration of regional anaesthesia near shoulder joint and upper arm.

Published: May 2022

This study discusses Artificial Intelligence in Library; Managing Bibliographic Data With Knowledge Base System In library activities such as indexing, cataloging, literature selection, archiving and references can be assisted by an expert system. Building an expert system using the Knowledge Base System in the library must be supported by command languages, output formats, database coverage, and the existence of literature search facilities including operations to correct errors when searching for information. The research was conducted by collecting information from various sources, then examining library services that could utilize artificial intelligence and explained descriptively. It is not as easy as turning the palm of the hand to bring artificial intelligence in the library. But once it is done, the library becomes a center of knowledge that is not boring. Even libraries can be present online in cyberspace.
