Published: January 2022

An eco-friendly and low cost modified mixture of both Wild Carob and Cupressus sempervirens with H3PO4 (Cupcar-H3PO4) was prepared to extract a cationic dye (Crystal Violet) from an aqueous solution in a batch reactor at the laboratory of chemical engineering, Department of Process Engineering, Faculty of Technology, Farhat Abbas Setif University-1. The pH effect, contact time, initial concentration of dye, ionic strength and temperature were investigated in this study. The Maximum adsorption capacity was found to be 117.26 mg/g at 25°C for a natural pH (ph =6.22). The active functional groups of Cupcar-H3PO4. These peak shifts indicated that especially the bonded –OH groups, C–O stretching of ether groups, and C=C group played a major role in CV adsorption onto Cupcar-H3PO4. The new bands of low intensity which appeared at 890 cm−1 and 813 cm-1 after CV adsorption and which could be attributed to a υ (CV-biosorbent) constituted the most striking result. Kinetics of biosorption of crystal violet (CV) was analyzed and the results showed that both pseudo order (PSO) and the pseud nth-order model (PNO) models gave most accurate fit than the pseudo-first-order model (PFO). Isotherm data were analyzed by four classical models, Langmuir and Freundlich with two parameters, Sips and Redlich-Peterson with three parameters. And for more information on the mechanism of CV uptake on the Cupcar-H3PO4 material, three advanced models are applied to isothermal data, Monolayer with one energy (M1), Monolayer with two energies (M2), and Double layer with one energy (M3). For the classical models and in the case of the two parameters models the Langmuir one gives a better fit for the data isotherm according to the R2. In the case of three parameters models, both Sips and Redlich-Peterson accurately described experimental data. Monolayer with two energy sites model (M2) was shown to be the most appropriate advanced statistical physics model for fitting CV biosorption onto the Cupcar-H3PO4 biosorbent, this model suggested that the CV pollutant was adsorbed at two different Cupcar-H3PO4 biosorbent sites, and that a variable number of CV molecules could be adsorbed at each site; from this, the CV dye was adsorbed with 2 different adsorption energies. The changes in the enthalpy, the standard free energy and the entropy were also evaluated and the reaction was found to be spontaneous, endothermic and physical in nature.

Published: January 2022

A 65-year-old male post-CABG surgery presented with history of ventricular storm refractory to antiarrhythmics and requiring multiple DC shocks. He got posted for VATs bilateral cardiac denervation for sympathetic remodulation. Patient was induced with high dose opioids and Etomidate and intubated with 37Fr left double lumen tube. A multidisciplinary approach was planned to tackle peri-operative cardiac event along with the placement of invasive monitors. Events that might lead to sympathetic overactivation because of laryngoscopy, pain, capnothorax, and surgical handling were kept in mind and avoided with optimum depth of anesthesia, analgesia, and pharmacological sympatholysis. There was no major cardiac event intraoperatively as well as in postoperative period.

Authors: Singh Vikrampal , Garg Arun , Singh Gurmeet , Kapoor Samir , Ralhan Sarju , Arya Rajesh , Mohan Bishav , Wander Gurpreet S , Gupta Rajiv K
Published: January 2022

Purpose:

The aim of this study is to analyze anticoagulation-related complications in patients following mechanical valve replacement and factors influencing the outcome.

Materials and Methods:

A total of 250 patients were analyzed during OPD follow-up for anticoagulation-related complications and various factors influencing outcome. Patients received prosthetic valve at mitral and/or aortic or both.

Results:

Out of 250 patients, 48% were male and 52% were female. The mean age was 41.9 ± 14.4. A total of 139 had mitral valve replacement (MVR), 70 had aortic valve replacement (AVR), 40 had double valve replacement (DVR), and 1 patient had triple valve replacement. Valves implanted were mechanical bileaflet valve. The mean international normalization ratio (INR) in the study was 2.4 ± 0.56. A total of 49 events occurred during follow-up, of which 4.5% per patient years were anticoagulation-related hemorrhagic events and 4.8% per patient years were thromboembolic events. Among thromboembolic events, valve thrombosis occurred in 10 patients and cerebrovascular accidents occurred in 11 patients. Mean INR for thromboembolic events was 1.46 ± 0.25 and anticoagulation-related hemorrhagic events was 4.4 ± 1.03. Mortality rate was 1.6% in AVR, 4% in MVR, and 0.4% in DVR groups; about 34% of patients needed dose modification of Acenocoumarol and reason for derangement of INR was associated with infectious process and poor compliance; 85% of cases showed good compliance for daily anticoagulation therapy.

Conclusion:

Anticoagulation for mechanical valve replacement can be managed with INR range of 2.0 to 2.5 in MVR and 1.5 to 2.0 in AVR with acceptable hemorrhagic and thromboembolic events. We must educate and counsel the patients during follow-up for better compliance to optimal anticoagulation.

The Role of Echocardiography in the Management of Structural Valve Degeneration of Transcatheter Valves
Authors: Shabadi Rahul , Desai Pushkar , Al-Kemyani Nasser , Al-Lawati Hatim
Published: January 2022

Transcatheter valve implantation in patients with aortic stenosis has evolved as an acceptable alternative to surgical aortic valve replacement in a subset of patients at excessively high risk from surgery. The structural valve degeneration (SVD) is a known phenomenon in catheter-based valves too, which was hitherto seen with surgical bioprosthetic valves. Echocardiography plays a pivotal role not only in early detection but also in the management of SVD of Transcatheter valves. The goal of this report is to agglomerate our experience of an unusual case of SVD of a catheter-based valve implanted inside the bioprosthetic aortic and mitral valve apparatus and its management with aortic and mitral valve replacement with mechanical valve prosthesis.

Published: January 2022

Objective:

Thoracic Epidural Analgesia (TEA) was compared with ultrasound-guided bilateral erector spinae plane (ESP) block in aorto-femoral arterial bypass surgery for analgesic efficacy, hemodynamic effects, and pulmonary rehabilitation.

Design:

Prospective randomized.

Setting:

Tertiary care centre.

Participants:

Adult patients, who were scheduled for elective aorto-femoral arterial bypass surgery.

Interventions:

It was a prospective pilot study enrolling 20 adult patients who were randomized to group A (ESP block = 10) and group B (TEA = 10). Monitoring of heart rate (HR) and mean arterial pressure (MAP) and pain assessment at rest and deep breathing using visual analog scale (VAS) were done till 48-h post-extubation. Rescue analgesic requirement, Incentive spirometry, oxygenation, duration of ventilation and stay in Intensive Care Unit (ICU) were reported as outcome measures. Statistical analysis was performed using unpaired Student T-test or Mann-Whitney U test. A value of P < 0.05 was considered significant.

Results:

HR was lower in group B than group A at 1 and 2 h post- surgery and at 0.5, 16, 20, and 32 h post-extubation (P < 0.05). MAP were lower in group B than A at 60, 90, 120, 150, 180, 210, 240, 270 minutes and at 0 hour post-surgery and at 4 hours, every 4 hours till 32 hours post-extubation (P < 0.05). Intraoperative midazolam and fentanyl consumption, ventilatory hours, VAS at rest, incentive spirometry, oxygenation, and ICU stay were comparable between the two groups. VAS during deep breathing was more in group A than B at 0.5, 4 hours and every 4 hours till 44 hours post-extubation. The time to receive the first rescue analgesia was shorter in group A than B (P < 0.05).

Conclusion:

Both ESP block and TEA provided comparable analgesia at rest. Further studies with larger sample size are required to evaluate whether ESP block could be an alternative to TEA in aorto-femoral arterial bypass surgery.
Unforeseen Rupture of Pseudoaneurysm of Common Carotid Artery
Authors: Das Devishree , Chauhan Sandeeep , Das Sambhunath , Praveen P.
Published: January 2022

Pseudoaneurysm of the common carotid artery (CCA) is exceptionally unstable and unpredictable; it mandates quick medical attention in order to circumvent neurologic sequelae or hemorrhage. Unanticipated rupture is extremely lethal and a potential provocation for the anesthesia caregiver. It is an arduous challenge for an anesthetist to establish emergency airway when a huge bleeding pseudoaneurysm is compressing and deviating the trachea, securing invasive lines in collapsing vessels, volume and vasopressor resuscitation in deteriorating hemodynamics in order to maintain cerebral perfusion without compromising other vital organs, arranging huge amount of blood and blood products in a short span of time, and transferring an exsanguinating patient for the rapid institution of cardiopulmonary bypass. Not only preoperatively it also necessitates appropriate neuromonitoring and neuroprotection during and after surgery. The association of unforeseen rupture of common carotid artery pseudoaneurysm secondary to the tubercular spine and lifesaving management by the rapid institution of cardiopulmonary bypass (CPB) is a rare occasion. To the best of the authors' knowledge, there is not any similar case in the peer-reviewed literature. Therefore, the authors enumerate the clinical experience of an unexpected rupture of CCA pseudoaneurysm requiring lifesaving CPB and emphasize the “Timely Teamed Effort Approach” that can sustain a life in such an inevitable situation.

Published: January 2022

Extra corporeal membrane oxygenation (ECMO) for refractory out-of-hospital cardiac arrest (OHCA) has been shown to improve outcome in many Western countries. There are no reports of ECMO being used to support OHCA in India till date. We report a case of a young man who developed cardiac arrest (CA) while driving and was given bystander cardiac massage. He was brought to tertiary care center where an ECMO was utilized for refractory CA. The patient subsequently underwent emergency coronary artery stenting and was weaned off ECMO and ventilation. We discuss the case and highlight the role of bystander cardiopulmonary resuscitation.

Authors: Maddali Madan Mohan , Al Shamsi Fathiya , Arora Nishant Ram , Venkatachlam Ramachandhiran , Sathiya Panchatcharam Murthi
Published: January 2022

Background:

Measurement of biomarkers representing sympathetic tone and the surgical stress response are helpful for objective comparison of anesthetic protocols.

Aims:

The primary aim was to compare changes in chromogranin A levels following pump pediatric cardiac surgery between children who received bolus caudal morphine and those who received a conventional intravenous narcotic-based anesthesia regime. The secondary objectives were to compare hemodynamic responses to skin incision and the magnitude of the rise in blood sugar values between the groups.

Settings and Design:

A prospective observational study at a tertiary cardiac center.

Measurements and Methods:

Sixty pediatric cardiac surgical patients were randomized to Group I [n = 30] to receive intravenous narcotic-based anesthesia and Group II [n = 30] to receive single-shot caudal morphine. Baseline and postoperative chromogranin A levels, the hemodynamic response to skin incision, changes in blood sugar levels, and the total intravenous narcotic dose administered were recorded for each participant.

Statistical Analysis:

Pearson's Chi-squared test was used for comparison of categorized variables, and Mann–Whitney test was used for the analysis of continuous data.

Results:

Changes in chromogranin A levels and blood sugar levels were comparable in both groups. Group II received a lower narcotic dosage (P ≤ 0.001), and the response to skin incision as reflected by systolic pressure rise was less (P = 0.006).

Conclusions:

Surgical stress response attenuation was similar to caudal morphine as compared with intravenous narcotic-based anesthesia techniques as reflected by a similar increase in chromogranin A levels.

Authors: Singh Avneet , Kumar Ganesh , Saini Kulbhushan , Prabhakaran Gangadharan
Published: January 2022

Congenital complete heart block (CCHB) has an incidence of one in 20,000 live births and carries a 20% risk of mortality. The hemodynamic instability due to bradycardia and asystole due to the increasing metabolic demands can be avoided by appropriate antenatal planning, timely delivery and initiation of medical treatment and early pacemaker insertion. In this report, we discuss the anaesthetic challenges of permanent epicardial pacemaker insertion with good outcomes in a 32-week gestational age 1380 grams neonate within a few hours of birth.

Authors: Ramachandran Riju , Gunasekharan Vaishnavi , Pillai Anoop Vasudevan , Raja Suyambu , Nair Anjaly S
Published: January 2022

Context:

Minimally invasive sphincter preserving procedures like ligation of intersphincteric fistula tract (LIFT) and video-assisted anal fistula treatment (VAAFT) are being increasingly used in the treatment of fistula-in-ano. The addition of adjuncts like fibrin glue has improved the results for VAAFT. Our unit has used platelet-rich fibrin (PRF) as an innovative adjunct for VAAFT.

Aims:

To compare the effectiveness of two different adjuncts, fibrin glue and autologous PRF, used to fill the treated fistula tracts following VAAFT.

Settings and Design:

Retrospective observational study on a cohort of patients undergoing VAAFT at a tertiary centre between 2015 and 2020 comparing two adjuncts used with VAAFT procedure.

Subjects and Methods:

Data of patients who underwent VAAFT for fistula-in-ano were obtained from the hospital database. Group A included patients treated with fibrin as adjunct and PRF as adjunct in Group B. Patients were followed up at 1, 3 and 6 months post-operatively and by a telephonic interview in 2020 to ascertain recent status. All data were entered into an excel sheet.

Statistical Analysis Used:

Data were analysed using SPSS V20 to test the statistical significance of the difference in the mean healing time between two groups, Mann–Whitney U-test was used and for age, Student's t-test was used.

Results:

There were 41 patients in Group A and 24 in Group B. There was a significant reduction in recurrence rate in Group B (P = 0.032) and in those patients who had a single internal opening (P = 0.045), single external opening (P = 0.03) and complex tracts (P = 0.033). PRF was cheaper than Fibrin glue.

Conclusions:

PRF is more effective and economical with lower recurrence rates.

Published: January 2022

Central nervous system infections are an uncommon cause of acute febrile encephalopathy (AFE) in the elderly. Scrub typhus meningoencephalitis is uncommon and often missed in the elderly. A 70-year-old male presented with complaints of intermittent fever, maculopapular rash, and altered sensorium. Physical examination revealed fever, tachycardia, tachypnea, maculopapular rash on the trunk, and all four limbs, and an eschar on the right thigh. Initial laboratory evaluation revealed anemia, thrombocytopenia, and azotemia. The cerebrospinal fluid revealed lymphocytic pleocytosis, elevated proteins with normal glucose, and adenosine deaminase. Weil–Felix test was positive. The diagnosis of scrub typhus meningoencephalitis with acute kidney injury and atypical pneumonia was established. A prompt treatment with injection doxycycline and tablet rifampicin led to an uneventful recovery. We report the first case of scrub typhus meningoencephalitis as the cause of AFE in the elderly. This case highlights the importance of clinical examination in any febrile encephalopathy presenting in endemic areas or travelers returning from such places.

Authors: Malhotra Tarun , Jha Shymal , Kamal Deep , Thakur Vaidehi
Published: January 2022

Background:

The prevalence of chronic otitis media in the Armed Forces is high. Moreover, management of high-risk perforation and atelectatic ear is an even greater challenge. It is necessary to assess the most viable management approach to achieve an optimal outcome.

Aims and Objectives:

We aimed to compare anatomical and audiological results in tympanoplasty for high-risk perforation and atelectasis using perichondrium-cartilage island (PCI) graft with temporalis fascia (TF) graft.

Materials and Methods:

A retrospective study was carried on 110 patients. Fifty-four patients and 56 patients underwent PCI graft and TF tympanoplasty, respectively. Postoperative graft integration rates and hearing outcomes were compared. Chi-square test was carried out to compare postoperative graft uptake. Postoperative audiological outcomes were compared using t-tests.

Results:

At 2-year follow-up, the graft take-up rate for PCI graft and TF graft was 96.29% and 82.14%, respectively (statistically significant). In the TF group, 17.86% had reperforation and recurrence of retraction pockets. In the PCI group, 3.71% had recurrent perforation. Furthermore, there was a statistically significant in the postoperative long-term improvement in pure-tone average air-bone gap in the cartilage island graft group (15.01 ± 3.53 db vs. 21.96 ± 4.09 db, P < 0.05).

Conclusion:

PCI graft achieves better morphological and audiological results in comparison to TF graft in high-risk perforation and atelectatic ears. It has a higher graft integration rate and better long-term audiological outcomes.

Authors: Saxena Apoorv , Shaw Subhash Chandra , John Biju M. , Adhikari K. M.
Published: January 2022

Background:

The COVID-19 pandemic has forced the world to change its approach to medical education with most of the undergraduate (UG) teaching shifting to online mode. As in other colleges in India, we also switched to online classes for both UG and postgraduate (PG) students in April 2020. We intend to share our preliminary experience about the acceptance and performance of these online classes in Pediatrics.

Methodology:

For UGs, we studied the attendance and marks of term ending summative assessment of batch of 2020 who attended online classes and compared them to the attendance and marks of the term ending summative assessment of the previous three batches (2017, 2018, and 2019). We also obtained a feedback on a prevalidated questionnaire from the UG as well as PG students.

Results:

The mean ± standard deviation (SD) attendance of the batch of 2020 was 81.6 ± 16.2%, while that of the 2017, 2018, and 2019 batch during the same period was 84.9 ± 10.9%, 92.6 ± 4.8%, and 83.0 ± 7.6% respectively. Similarly, the mean ± SD marks for the batch of 2020 was 74.8 ± 6.5% while it was 66.9 ± 9.4%, 58.6 ± 10.1%, and 60.9 ± 9.7% for 2017, 2018, and 2019 batches, respectively. The feedback obtained from both UGs and PGs was satisfactory in relation to the acceptance of the online mode.

Conclusion:

The online classes in Pediatrics are a reasonable alternative to the onsite classes in the prevailing situation.
Assessment of the knowledge, attitude, and practices of OB-GYN consultants and residents on the screening of postpartum depression
Authors: Loquero Cristyne G. , Galbo Pherdes E.
Published: January 2022

INTRODUCTION:

Postpartum depression (PPD) is a major health concern for child-bearing women and has its effects on her children. Advocacies for mental health have paved way for more awareness of conditions such as PPD. Currently, there is no particular screening protocol employed by attending physicians of these women. There is also a lack of data that determines the practices of obstetricians when dealing with patients with PPD or those at risk of developing it.

OBJECTIVE:

This descriptive study evaluated the knowledge, attitudes, and practices of OB-GYN consultants and residents on the screening of PPD.

MATERIALS AND METHODS:

A validated questionnaire was utilized with some modifications made to tailor fit the targeted population. All affiliated consultants and residents of the Philippine Obstetrical and Gynecological Society-accredited training hospitals in a Region VII were included while those retired were excluded. The Google Form link of the questionnaire was disseminated to the different institutions who gave approval to conduct the study. Anonymity and confidentiality of data acquired were maintained throughout the study.

RESULTS:

A total of 110 responses were received. The key findings of the study showed that the respondents have above average knowledge on PPD including its risk factors, symptoms, complications, and treatments. They generally have positive beliefs toward their role in the screening and management of PPD. Moreover, majority of them have already tried screening for PPD although not routinely.

CONCLUSION:

There is a significant relationship between the knowledge, attitude, and practices of the consultants and residents on the screening of PPD. Systems should be put in place to ensure effective treatment and follow-up of patients and thus impact good clinical outcomes.
Struma ovarii-associated pseudo-Meigs− syndrome with concomitant abdominopelvic tuberculosis masquerading as ovarian malignancy
Authors: Dionisio Nicole Anna Marie H. , Jacinto Elizabeth K.
Published: January 2022

Pseudo-Meigs' syndrome (PMS) is a rare disease characterized by the triad of (1) an ovarian neoplasm, other than a fibroma or thecoma, (2) ascites, and (3) pleural effusion. Tumors such as struma ovarii, mucinous and serous cystadenomas, and germ cell tumors have been linked with the condition. Due to its clinical features combined with the elevation of serum cancer antigen 125 (CA-125) levels, it is often mistaken and treated as a malignant ovarian tumor. Ascites or pleural effusion could be massive leading to various life-threatening complications. Despite its presentation, this entity has an excellent prognosis when surgical excision of the tumor is performed. This article presents an unusual case of a 41-year-old gravida 10 para 10 (10-0-0-9) who was diagnosed with a case of struma ovarii associated PMS with concomitant abdominopelvic tuberculosis and elevated CA-125 resembling an ovarian malignancy.

Authors: KILINÇ Hasan Erkan , ÜNVER Banu
Published: January 2022

Objective: Mechanical neck pain is a very common problem in society and can lead to disability. In modern societies, increasing expectations from individuals in work, family and social life have brought along sleep disorders, mental and physical fatigue. The aim of our study was to examine the effects of sleep disorder, mental and physical fatigue on mechanical neck pain.Method: Two hundred fifty-two individuals with mechanical neck pain having a mean age of 28.01±9.97 years were included in our study. Neck Disability Index, Chalder Fatigue Scale, and Pitssburg Sleep Quality Index were applied to all individuals.Results: According to the regression analysis results, only the mental fatigue sub-dimension of the Chalder Fatigue Scale was associated with increased Neck Disability Index score (β=0.169, p=0.036). Pitssburgh Sleep Quality Index and the physical sub-dimension of Chalder Fatigue Scale were found not to have a significant effect on Neck Disability Index score (p>0.05).Conclusion: Mental fatigue was found among the independent determinants of neck disability. Therefore, a more holistic approach including mental fatigue should be adopted in the treatment of mechanical neck pain.

Peneliti melakukan uji perbandingan metode ekstraksi fitur dan leksikon bahasa Indonesia pada analisis sentimen teks di media sosial terkait penanganan Covid-19. Set data yang digunakan berasal dari penelitian sebelumnya yang divalidasi ahli bahasa. Penelitian ini bertujuan mengukur performa kamus sentimen kata dari leksikon InSet dan sentistrength_id terhadap label aktual, berikutnya untuk mengetahui pengaruh pemilihan metode ekstraksi fitur term presence, BoW, dan TF-IDF. Proses penelitian dimulai dengan tahap prapengolahan teks, pemilihan metode ekstraksi fitur, pelabelan kata dengan leksikon, dan klasifikasi sentimen dengan Support Vector Machine (SVM). Evaluasi akhir dilakukan dengan k-Fold cross validation menggunakan data yang disintesis dengan algoritma SMOTE. Pengujian awal menunjukkan bahwa kamus sentimen kata leksikon sentistrength_id menghasilkan skor akurasi sedikit lebih tinggi (64,46%) dibanding InSet (62,65%) saat dikombinasikan dengan TF-IDF. Di tahap evaluasi akhir, kamus sentimen kata sentistrength_id masih menunjukkan performa yang relatif lebih baik berdasarkan rerata nilai akurasi, presisi, sensitivitas, dan f-measure (59,22%, 61,1%, 31,3%, 41,0%) dibanding InSet (58,98%, 62,2%, 26,1%, 36,6%) saat dikombinasikan dengan TF-IDF. Secara umum, performa kedua leksikon memang masih di bawah data dengan label aktual yang mengindikasikan kedua leksikon belum cukup kuat dalam menentukan kelas kata. Penyebabnya bisa karena jumlah data yang relatif sedikit atau karena normalisasi teks belum cukup dilakukan secara maksimal.

Fungos do gênero Candida fazem parte da microbiota normal e pode causar infecções em indivíduos imunocomprometidos, com o auxílio de seus fatores de virulência. Os profissionais da saúde podem ser uma possível fonte de infecção no ambiente hospitalar. Foram avaliados fatores de virulência como atividade de proteinase e fosfolipase, fator hemolítico e a resistência a antifúngicos em 37 isolados de Candida albicans e 10 C. parapsilosis provenientes da saliva de profissionais da saúde. A atividade de proteinase foi observada em 84% dos isolados de C. albicans e 80% de C. parapsilosis e destas, atividade fortemente positiva foram obtidas para 46% e 50% respectivamente. A atividade de fosfolipase foi observada para 80% dos isolados de C. parapsilosis, embora nenhum com atividade fortemente positiva, enquanto 92% dos isolados de C. albicans produziram fosfolipase, sendo que 19% destes apresentaram atividade fortemente positiva. A maioria dos isolados apresentaram hemólise total (beta hemólise) em ágar Sabouraud dextrose suplementado com sangue de carneiro e glicose, com média do diâmetro da hemólise de 2,41 e 2,57 para C. albicans e C. parapsilosis respectivamente. A avaliação da suscetibilidade antifúngica por disco difusão não demonstrou a presença de isolados resistentes ao fluconazol, itraconazol, voriconazol e anfotericina B, porém 8 isolados de C. albicans e 1 de C. parapsilosis se mostraram dose dependente, ao quando avaliados com o itraconazol. A detecção de isolados de C.albicans e C. parapsilosis isolados da saliva de profissionais da saúde, produtores de importantes fatores de virulência, como proteinase, fosfolipase e fator hemolítico, responsáveis pelo estabelecimento da infecção, evidenciam a necessidade de medidas de prevenção para evitar a transmissão exógena destes patógenos, especialmente no ambiente hospitalar.

Published: January 2022

Due to the fact that the pandemic process did not occur in a predictable time frame, various difficulties have arisen in the field of education. This is also true in mathematics education, and concretization has been one of the biggest obstacles. This situation paved the way for concept learning errors that may occur in students. There are some basic problems encountered in teaching the subject of slope. In this study, the purpose was to evaluate the concept learning deficiencies encountered in teaching the subject of slope by using real life problems with the help of Geogebra. The study had an action research design based on a qualitative approach. The participants of the study were 13 8th grade students attending a public school in Turkey. As the data collection tool, the activity named Bicycle-Slope, which was prepared by Kavak (2013) and which was available on the website of Geogebra, was used. In addition, 4 sub-questions were directed to the students. Moreover, the data were photographed with a camera, recorded with a voice recorder and analyzed descriptively. At the end of the study, when the responses of the students were observed, it was seen that there was a decrease in most of the concept learning errors that occurred.

Authors: Kanapathipillai Kumaran , Shaari Aida Binti , Mahbob Nur Nadiah
Published: January 2022

Fundamentally, all employees can recognise the objectives they want to achieve and plan changes they want to implement in an organisation to attain better job performance. However, most employees also understand that commissioning these plans into reality is not easy. Psychologists have identified that workers' self-efficacy plays a significant role in tackling tasks and challenges in organisations. This research illuminates current situations regarding the significance of self-efficacy on employees' job performance in the online retail sector in Malaysia. A total of 511 employees attached to the online retail sector provided the data for this research. Additionally, in-depth literature was assessed, revealing the relationship between self-efficacy, innovative behaviour, and job performance. Moreover, the intervening effect of innovative behaviour on the relationship between self-efficacy and employees' job performance was also investigated to verify the research hypothesis. The findings of this research established a statistically significant relationship between self-efficacy and innovative behaviour as well as employees' job performance. Conclusively, the hypothesis is supported by data and illustrated that innovative behaviour statistically mediates the relationship between self-efficacy and employees' job performance in the online retail sector in Malaysia. This study also validates that employees who have high self-efficacy are willing to embrace innovative behaviour, which then leads to enhanced job performance. In conclusion, self-efficacy with the intervention of innovative behaviour can heighten the employees' job performance in the online retail sector in Malaysia.

POLITICAL LEADERSHIP FROM WILLIAM GOLDING’S PERCEPTION IN LORD OF THE FLIES / LE LEADERSHIP POLITIQUE INSPIRE PAR L'APPROCHE DE WILLIAM GOLDING DANS LORD OF THE FLIES
Authors: Dansou Bertin Yélindo
Published: January 2022

William Golding’s perception of democratic leadership promotion versus dictatorial one for sustainable development has been challenged through times. This relaunches the debate about ideal political leadership for development, in spite of several reforms or changes yet shown successful. The purpose of this analysis is to get inspiration from the writer’s limited view on the issue to demonstrate that sustainable development is rather a matter of good leadership adapted to socio-political, cultural, scientific and economic contexts of societies than that of only well-built democracy versus totalitarianism. Psycho-analytical and historicist approaches have enlightened this study for which it is expected a new form of contextualised and ideal leadership, shaped for the true sustainable development of all the countries of the world.

Le point de vue de William Golding sur la promotion d’un leadership démocratique contre celui dictatorial pour le développement durable a été défié par l’usure du temps. Ceci relance le débat au sujet d’un leadership politique idéal et favorable à ce développement, malgré plusieurs réformes ou changements pourtant démontrés réussis. L’objectif de cette analyse est de partir de la compréhension limitée de l’auteur sur la question pour montrer que le développement durable est plutôt une affaire d’un leadership adapté aux contextes socio-politiques, culturels, scientifiques et économiques des sociétés que celle seulement d’une démocratie bien établie contre le totalitarisme. Les approches psycho-analytique et historiciste ont orienté cette réflexion dont on attend une nouvelle forme contextualisée et idéale de leadership élaborée pour le vrai développement durable des pays et du monde.

Authors: Çilkiz Mustafa , Özdal Mustafa
Published: January 2022

The aim of this study is to examine the effect of cerebral lateralization on drag-flick and shot performance in hockey. For this purpose, 35 elite hockey players participated in the study as subjects. After the lateralization test was applied, the subjects were divided into three groups as dominant right hand, dominant left hand and using both hands, and then shot and drag flick tests were applied to the subjects to determine the effect of lateralization on hockey skills between the groups. The obtained data were analyzed in SPSS 22.0 program. After testing for normality and homogeneity, one-way analysis of variance and LSD correction were performed for multiple groups. When the results were examined, it was determined that hand preference had a significant effect on shooting performance and drag flick performance in favor of right and left hand dominant (p<0.05). As a result, it can be said that the effects of laterization are in favor of the dominant hand in hockey players regardless of whether they are right or left, and individuals using both hands perform negatively in hitting advantageous points.

Authors: Sever Canan , Akcan Fırat
Published: January 2022

It is thought that knowing the situations that minimize the negative effects of Covid-19 on human health will be useful in the fight against the epidemic. In this study, it was aimed to investigate the relationship between the level of physical activity and the effect of Covid-19 on quality of life. 200 people who had previously had Covid-19 participated in the study voluntarily. An international physical activity questionnaire was applied to the participants to determine their pre-disease physical activity levels, and an international quality of life scale was applied to determine the effect of Covid-19 on the quality of life during the disease. SPSS 22 package program was used in the analysis of the data. In the study, the relationship between age, marital status, gender, education and physical activity level and the effect of Covid-19 disease on quality of life was examined. There was no statistically significant difference between the age, gender and marital status of the participants and the scores they got from the quality-of-life questionnaire (p<0.05). On the other hand, there was a statistically significant difference between the education levels of the participants and the scores they received from the quality of life, between those who received high school education and those who received education at the undergraduate level, in favor of those who received undergraduate education, in general health scores and social health scores (p<0.05). On the other hand, the general health score between the physical activity level and the quality-of-life scores, the physical activity level between the active and the very active, in favor of the very active, the general health score between the inactive and the active and the very active, the general health score in favor of the active and very active statistically significant difference was found (p<0.05). As a result, it can be said that those with good educational status and those with active and very active physical activity levels are more advantageous in feeling less of the symptoms associated with Covid-19 and reducing its negative impact on quality of life.
